JP-A-7-103504

  In the above-described conventional technology, the humidified air passing through the humidified air passage in the air passage is heated by the thermoelectric conversion element. Therefore, when humidified air becomes high temperature, there exists a problem that a high temperature humidified air is blown out from a humidified air channel | path, and the user of a dehumidifying / humidifying device gives discomfort. As a means for solving such a problem, there is a method of newly adding a cooling means for cooling the humidified air. However, if a cooling means is newly added, the size of the dehumidifying / humidifying device becomes large, and the configuration of the dehumidifying / humidifying device is increased. There is a problem of complexity. Further, as another means for solving the above-mentioned problem, it is conceivable to use an adsorbent having a low moisture release temperature, but since an adsorbent having a low release temperature has low adsorption performance, it is necessary to use a large amount of adsorbent, There is a problem that the physique of the dehumidifying / humidifying device becomes large.

  Accordingly, the present invention has been made in view of the above-described problems, and an object thereof is to provide a dehumidifying / humidifying device capable of adjusting the temperature of humidified air with a simple configuration.

  The present invention employs the following technical means in order to achieve the aforementioned object.

The present invention comprises a casing (1) in which a humidified air passage (80) through which humidified air passes and a dehumidified air passage (90) through which dehumidified air passes,
A blowing means (2) for blowing air into the casing;
An air-conditioning means (3) provided in the casing for humidifying and dehumidifying the air blown by the blowing means, which is formed in a plate shape, and one of the surface portions in the thickness direction is the heat absorbing portion. A first Peltier element (30A) that functions as one of the Peltier elements (30A), the other surface part of which functions as a heat radiating part, and that adsorbs and releases moisture based on the temperature of one of the Peltier elements. ), And an air conditioner having a second adsorbing element (31B) provided on the other surface portion of the Peltier element and adsorbing and releasing moisture based on the temperature of the other surface portion;
Provided on the downstream side of the first adsorption element, the air after passing through the first adsorption element passes, and adsorbs and releases moisture based on the temperature of the air after passing through the first adsorption element. A first adsorption part (51A);
Provided on the downstream side of the second adsorbing element, air after passing through the second adsorbing element passes, and adsorbs and releases moisture based on the temperature of the air after passing through the first adsorbing element. A second adsorption part (51B);
Air that has passed through the first adsorbing section is guided to the humidified air passage, and air that has passed through the second adsorbing section is guided to the dehumidifying air passage, and air that has passed through the first adsorbing section is guided to the dehumidifying air passage. And a dehumidifying / humidifying device comprising: a state in which the air that has passed through the second adsorbing portion is guided to the humidified air passage; and a flow path switching means (4) that switches over the state.

  According to the present invention, the humidified air humidified by the air conditioning means passes through the first adsorption part or the second adsorption part, and passes through the humidified air passage by the flow path switching means. The first adsorption unit and the second adsorption unit (hereinafter, these two adsorption units may be collectively referred to as “cooling adsorption unit”) adsorb and release moisture based on the temperature of the air passing therethrough. Therefore, the air humidified by the air conditioning means can be further humidified by the first adsorption unit or the second adsorption unit. In this way, since the humidification is further performed by the cooling adsorption unit, the temperature of the passing air can be lowered by the latent heat of vaporization when water is released. As a result, the temperature of the humidified air can be adjusted. Further, the dehumidifying / humidifying device of the present invention can be realized with a simple configuration in which a cooling adsorbing portion that is a means that does not need to be operated electrically and mechanically is provided without newly providing a cooling means.

In the present invention, the first adsorption element, the second adsorption element, the first adsorption unit, and the second adsorption unit have the same absolute humidity.
The lower discharge limit temperature, which is the lowest temperature in the release temperature range for releasing moisture in the first adsorption unit and the second adsorption unit, is lower than the lower release temperature of the first adsorption element and the second adsorption element. To do.

  According to the present invention, the lower limit discharge temperature of the first adsorption element and the second adsorption element (hereinafter, these two adsorption elements may be collectively referred to as “air-conditioning adsorption element”) is heated by the Peltier element. Is set based on the temperature of the surface portion to be applied. Therefore, the air humidified by the air conditioning adsorption element is equal to or higher than the lower limit discharge temperature of the air conditioning adsorption element. In addition, the cooling adsorption unit adsorbs and releases moisture based on the temperature of the ambient air passing through, but the cooling adsorption unit passes by making the lower emission lower limit temperature of the cooling adsorption unit lower than the lower release temperature of the air conditioning adsorption element. The adsorbing part for cooling can be set to the discharge lower limit temperature or higher by the humidified air. In this way, the humidified air passes through the cooling adsorption unit, so that the cooling adsorption unit is warmed, the moisture adsorbed by the cooling adsorption unit is released, and the humidified air can be reliably cooled.

In the present invention, the first adsorption element, the second adsorption element, the first adsorption unit, and the second adsorption unit have the same absolute humidity.
The adsorption upper limit temperature which is the maximum temperature in the adsorption temperature range for adsorbing moisture in the first adsorption unit and the second adsorption unit is lower than the adsorption upper limit temperatures of the first adsorption element and the second adsorption element. To do.

  According to the present invention, the air dehumidified by the air conditioning adsorption element is equal to or lower than the adsorption upper limit temperature of the air conditioning adsorption element. The cooling adsorption unit adsorbs and releases moisture based on the temperature of the air passing therethrough, but dehumidification passes by making the upper limit adsorption temperature of the cooling adsorption unit lower than the upper adsorption temperature of the air conditioning adsorption element. The cooling adsorption part can be brought to the adsorption upper limit temperature or less by the wind. In this way, the dehumidifying air passes through the cooling adsorption unit, whereby the cooling adsorption unit is cooled, and the cooling adsorption unit can further adsorb moisture. Thereby, it can be set as the dehumidification wind with little water | moisture content.

  Furthermore, the present invention is characterized by further including a heat insulator (50) that insulates the first adsorbing portion and the second adsorbing portion.

  According to the present invention, since the first adsorbing portion and the second adsorbing portion are insulated by the heat insulator, even if the humidified air passes through one adsorbing portion, the other adsorbing portion is humidified air. Can be prevented from being heated. Thereby, the adsorption part for cooling can adsorb | suck and discharge | release a water | moisture content based on the temperature of the humidification air or dehumidification air which passes. By using the heat insulator in this way, it is easy to adjust the temperature at which the cooling adsorption unit can exhibit a desired dehumidifying / humidifying function.

  In addition, the code | symbol in the bracket | parenthesis of each above-mentioned means is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan sectional view showing a dehumidifying / humidifying device 100 according to the first embodiment. FIG. 2 is a side sectional view of the dehumidifying / humidifying device 100. The dehumidifying / humidifying device 100 of the present embodiment is applied to, for example, a vehicle dehumidifying / humidifying device 100 that is mounted in a vehicle interior of a vehicle and takes in the vehicle interior air and blows out dehumidified air and humidified air. The dehumidifying / humidifying device 100 is used for supplying dehumidifying air for defogging to the inner surface side of the vehicle front window glass and supplying humidified air to the occupant side, for example, in winter when the outside air dries. The dehumidifying / humidifying device 100 is installed, for example, on a ceiling portion in a vehicle interior. The dehumidifying / humidifying device 100 includes a casing 1, a blower 2, an adsorption module 3, a cooling module 25, a flow path switching unit 4, an actuator 7, and a control device (not shown).

  The casing 1 forms a flow path through which air flows. The casing 1 is formed in a longitudinal shape so as to extend along the flow direction in which air flows. In the casing 1, the adsorption module 3 and the flow path switching unit 4 are sequentially arranged along the air flow direction. The casing 1 can be designed in various shapes depending on the installation location. For example, the casing 1 is formed in a flat, substantially rectangular parallelepiped box shape in which a thickness portion corresponding to the height is designed to be thin in order to be installed on a ceiling in a vehicle interior. The Further, the casing 1 may be formed with a curved outer shape according to the ceiling shape. The casing 1 is made of resin, for example.

  Hereinafter, the direction in which the casing 1 extends and the direction in which air flows is referred to as the length direction Y (left-right direction in FIG. 1), and the direction orthogonal to the length direction Y is the width direction X (up-down direction in FIG. 1). The direction perpendicular to the length direction Y and the width direction X may be referred to as a thickness direction Z (direction perpendicular to the paper surface of FIG. 1).

  In the casing 1, a main passage 26, a humidified air passage 80 and a dehumidified air passage 90 are formed as passages through which air blown from the blower 2 flows. The main passage 26 is provided upstream of the humidified air passage 80 and the dehumidified air passage 90. The air that has passed through the main passage 26 is sent to the humidified air passage 80 and the dehumidified air passage 90, respectively. A suction port 10 that opens outward is formed at one end in the length direction Y of the casing 1 in order to send air to the main passage 26.

  The humidified air passage 80 is formed by an inner wall portion of the casing 1 and is a passage through which air flows separately from the dehumidified air passage 90. In other words, the humidified air passage 80 and the dehumidified air passage 90 are formed as independent passages by the inner wall portion of the casing 1. Therefore, the humidified air flowing through the humidified air passage 80 does not flow through the dehumidified air passage 90. The other end of the casing 1 in the length direction Y (the left side in FIG. 1), which is the downstream end of the air flow, flows down the humidified air outlet 8 from which the humidified air that has flowed down the humidified air passage 80 and the dehumidified air passage 90 flow down. The dehumidified air outlet 9 from which the dehumidified air blown out is provided side by side in the width direction X. The humidified air outlet 8 and the dehumidified air outlet 9 are defined by a partition wall 11 formed integrally with the casing 1. In this embodiment, the humidified air outlet 8 is formed smaller than the humidified air outlet 9. Yes. The humidified air outlet 8 is connected to, for example, a face outlet duct (not shown) directed toward the passenger side, and the dehumidified air outlet 9 is connected to a defroster outlet duct (not shown) directed to, for example, a vehicle front window glass. ) Is connected.

  The blower 2 is a blowing means, and is provided at one end of the casing 1 in the longitudinal direction Y (right side in FIG. 1). The blower 2 is a centrifugal blower 2 including, for example, a multiblade fan 21, a radial fan, a turbo fan, and the like, and is configured to blow out the air sucked from the rotational axis direction outward in the radial direction. The blower 2 according to the present embodiment includes a flat scroll casing 20 formed of resin, a multi-blade fan 21 disposed therein, and a blower motor 22 that drives the multi-blade fan 21.

  The scroll casing 20 forms an outlet 24 for the multiblade fan 21 to send out air. The scroll casing 20 is a wall portion facing the radial direction of the multiblade fan 21. The scroll casing 20 surrounds the multiblade fan 21 from the outside in the radial direction, and forms a spiral flow path that gradually expands toward the air outlet 24.

  An opening 23 for allowing air from outside to flow into the scroll casing 20 is formed in the lower surface portion of the scroll casing 20 in the other thickness direction Z (downward in FIG. 2). As a result, the air flowing into the scroll casing 20 from the opening 23 is rectified in the radial direction and the circumferential direction by the spiral flow path, and is sent from the outlet 24 toward the other side in the length direction Y. The blower outlet 24 of the blower 2 is connected to the suction port 10 formed on one side in the length direction Y of the casing 1, and supplies the sucked air into the casing 1.

  Next, the adsorption module 3 will be described with reference to FIG. FIG. 3 is a perspective view showing the adsorption module 3. The adsorption module 3 is provided in the main passage 26. The adsorption module 3 is configured to allow air to pass through. The adsorption module 3 is air conditioning means, and humidifies and dehumidifies the air blown by the blower 2. The adsorption module 3 includes a Peltier element 30, a first adsorption element 31A, and a second adsorption element 31B.

  The Peltier element 30 is a plate-like thermoelectric element that utilizes the Peltier effect. When energized, the Peltier element 30 performs an endothermic action on the one end face side in the thickness direction Z and exerts a heat dissipating action on the other end face side in the thickness direction Z. It is. In the Peltier element 30, a large number of P-type semiconductors and N-type semiconductors are arranged between two types of metal plates, one metal plate forms an NP junction, and the other metal plate forms a PN junction. In such an element, heat transfer occurs when an electric current is passed through the PN junction, an endothermic phenomenon occurs in one metal plate, and a heat dissipation phenomenon occurs in the other metal plate. The Peltier element 30 is formed in a plate shape, and two plate surface portions 30a and 30b orthogonal to the thickness direction Z function as a heat absorbing portion and a heat radiating portion.

  The first adsorption element 31 </ b> A is provided on one plate surface portion 30 a in the thickness direction Z of the Peltier element 30. The second adsorption element 31B is provided on the other plate surface portion 30b in the thickness direction Z of the Peltier element 30. Since the first adsorbing element 31A and the second adsorbing element 31B have substantially the same configuration, only the first adsorbing element 31A will be described, and the description of the second adsorbing element 31B will be omitted. The first adsorption element 31 </ b> A adsorbs and releases moisture based on the temperature of one plate surface portion 30 a of the Peltier element 30. When the first adsorption element 31A is cooled, the amount of moisture absorption increases, absorbs moisture, and dehumidifies the passing air. Further, when the first adsorption element 31A is heated, the amount of moisture absorption is reduced, moisture is released, and the passing air is humidified.

  The first adsorption element 31 </ b> A includes an air conditioning substrate 32 and an air conditioning fin 33, and an air conditioning adsorbent is applied to the surfaces of the air conditioning substrate 32 and the air conditioning fin 33. The air conditioning substrate 32 and the air conditioning fins 33 are formed of a metal having excellent thermal conductivity such as aluminum. The air conditioning substrate 32 has a flat plate shape and is provided so as to be stacked on the plate surface portion 30 a of the Peltier element 30. A plurality of air conditioning fins 33 are provided so as to protrude outward in the thickness direction Z from the air conditioning substrate 32. A plurality of air conditioning fins 33 are provided so as to extend along the length direction Y, and are provided so as to be separated in the width direction X.

  The air-conditioning adsorbent is preferably a material that readily adsorbs moisture at a low humidity and can easily desorb at a low temperature, such as zeolite. In the adsorption module 3, the adsorption elements 31 </ b> A and 31 </ b> B generate heat and cold generated by the Peltier element 30 with respect to the plate surface portions 30 a and 30 b of the Peltier element 30 without interposing an air layer or other heat insulation elements. It only needs to be disposed so as to be transmitted by conduction, and may be disposed via a heat conductive material such as silver paste or heat transfer grease.

  The adsorption module 3 is configured such that the direction of the current flowing in the Peltier element 30 is reversed at time intervals according to the adsorption and desorption operations of the adsorption elements 31A and 31B, for example, at intervals of 5 minutes to 10 minutes. Control is performed so that the heat absorption function and the heat radiation function in the surface portions 30a and 30b are interchanged. In the adsorption module 3, the direction of the current is reversed before the adsorption element on the heating side completely releases moisture.

  Next, the cooling module 25 will be described. The cooling module 25 is provided in the main passage 26 and is provided adjacent to the other side in the longitudinal direction Y of the adsorption module 3. The cooling module 25 is configured to allow air to pass through. The cooling module 25 further humidifies and dehumidifies the air that has passed through the adsorption module 3. The cooling module 25 includes a heat insulator 50, a first suction part 51A, and a second suction part 51B. The cooling module 25 has the same configuration as that of the suction module 3 described above, and a heat insulator 50 is arranged instead of the Peltier element 30 of the suction module 3 described above. The cooling module 25 has substantially the same external shape as the adsorption module 3 shown in FIG.

  The heat insulator 50 is a plate-like member having heat insulation properties, and the first suction portion 51A and the second suction portion 51B are provided on the two heat insulation surface portions 50a and 50b orthogonal to the thickness direction Z, respectively. The heat insulator 50 is provided adjacent to the other side in the length direction Y of the Peltier element 30. The external shape of the heat insulator 50 is substantially the same as the external shape of the Peltier element 30, and the two heat insulating surface portions 50 a and 50 b of the heat insulator 50 are arranged so as to be flush with the two plate surface portions 30 a and 30 b of the Peltier element 30. Is done. The heat insulator 50 is air that has passed through the adsorption module 3, and the air that has passed through the first adsorption element 31A and the air that has passed through the second adsorption element 31B do not move and mix in the thickness direction Z. It is provided so as to partition the inside of the casing.

  The first suction portion 51 </ b> A is provided on one heat insulating surface portion 50 a in the thickness direction Z of the heat insulating body 50. The second adsorption portion 51B is provided on the other heat insulating surface portion 50b in the thickness direction Z of the heat insulating body 50. The air that has passed through the first adsorption element 31A passes through the first adsorption unit 51A. The air that has passed through the second adsorption element 31B passes through the second adsorption unit 51B. The first adsorption unit 51A adsorbs and releases moisture based on the temperature of the air that has passed through the first adsorption element 31A. Similarly, the second adsorption unit 51B adsorbs and releases moisture based on the temperature of the air that has passed through the second adsorption element 31B. Accordingly, the temperature of the air passing through the adsorption portions 51A and 51B differs greatly depending on whether the adsorption elements 31A and 31B are heated or absorbed. Based on this temperature, the adsorption portions 51A and 51B Adsorb and release moisture.

  Next, the configuration of the first suction unit 51A will be described. Since the first suction part 51A and the second suction part 51B have substantially the same configuration, only the first suction part 51A will be described, and the description of the second suction part 51B will be omitted. 51 A of 1st adsorption | suction parts contain the board | substrate for cooling (not shown) and the fin for cooling (not shown), and the adsorption material for cooling (not shown) is apply | coated to the surface of the board | substrate for cooling and the fin for cooling. Is done. The cooling substrate and the cooling fin are formed of a metal having excellent thermal conductivity such as aluminum. The cooling substrate has a flat plate shape and is provided so as to be laminated on the heat insulating surface portions 50 a and 50 b of the heat insulating body 50. A plurality of cooling fins are provided in a shape protruding from the cooling substrate outward in the thickness direction Z. The cooling fin has a shape extending along the length direction Y, and the plurality of cooling fins are provided so as to be separated in the width direction X.

  Next, the adsorption characteristics of the first adsorption unit 51A will be described. The adsorption characteristic of the first adsorption unit 51A is determined by the adsorption characteristic of the cooling adsorbent applied to the cooling substrate and the cooling fin. The adsorption characteristic of the second adsorption part 51B is the same as that of the first adsorption part 51A because the same cooling adsorbent as that of the first adsorption part 51A is used. The cooling adsorbent is preferably a material such as zeolite that can easily adsorb moisture at low humidity and easily desorb at a low temperature.

  FIG. 4 is a graph showing an example of the adsorption characteristics of the cooling adsorbent and the air conditioning adsorbent. The horizontal axis of the graph shown in FIG. 4 indicates temperature (° C.), and the vertical axis indicates the amount of adsorption (g) per 1 g of the adsorbent dry weight. In FIG. 4, the waveform of the air-conditioning adsorbent is when the absolute humidity is 0.014 g / g (the waveform M3 indicated by the solid line among the three waveforms on the right side of FIG. 4) and when the absolute humidity is 0.010 g / g. (A waveform M2 indicated by a one-dot chain line among the three waveforms on the right side in FIG. 4) and 0.006 g / g (a waveform M1 indicated by a broken line among the three waveforms on the right side in FIG. 4). Show. In FIG. 4, the waveform of the cooling adsorbent is 0.006 g / g when the absolute humidity is 0.014 g / g (the waveform L2 shown by the solid line of the two waveforms on the left side of FIG. 4). (The waveform L1 indicated by a broken line among the two waveforms on the left side in FIG. 4).

  As shown in FIG. 4, the waveforms L1, L2 of the adsorbent for cooling and the waveforms M1, M2, M3 of the adsorbent for air conditioning are both waveforms having inflection points. The adsorbent for cooling has a state in which the amount of adsorption is large when the temperature is lower than the transition temperature range, for example, the amount of adsorption is 0.15 g or more, based on the transition temperature range including the inflection point. Further, the air-conditioning adsorbent has a state in which the amount of adsorption is large when the temperature is lower than the transition temperature range, for example, the amount of adsorption is 0.22 g or more, based on the transition temperature range including the inflection point.

  The adsorbent for cooling and the adsorbent for air conditioning are in a state where the amount of adsorption is small, for example, the amount of adsorption is 0.03 g or less, when the temperature is higher than the transition temperature range based on the temperature in the transition temperature range. Thus, the temperature lower than the transition temperature range is an adsorption temperature range for adsorbing moisture, and the temperature higher than the transition temperature range is a release temperature range for releasing moisture. The minimum temperature in the transition temperature range is an adsorption upper limit temperature that is the maximum temperature in the adsorption temperature range where a large amount of moisture is adsorbed. The maximum temperature in the transition temperature range is the lower limit release temperature that is the lowest temperature in the release temperature range that releases a large amount of moisture.

  As shown in FIG. 4, the cooling adsorbent is located at a temperature at which the inflection point is lower than that of the air-conditioning adsorbent at the same absolute humidity. The temperature at the inflection point is the temperature at the center of the transition temperature range. Therefore, at the same absolute humidity, the adsorption upper limit temperature of the cooling adsorbent is lower than the adsorption upper limit temperature of the air conditioning adsorbent, and the cooling lower limit release temperature of the cooling adsorbent is lower than the lower release temperature of the air conditioning adsorbent.

  Next, the cooling adsorbent and the air-conditioning adsorbent will be described using an example of the numerical values shown in FIG. The amount of humidification necessary to make the passing air into humidified air is, for example, 1 g of moisture. The absolute humidity before humidification is, for example, 0.006 g / g, and the absolute humidity after humidification is, for example, 0.014 g / g. The temperature of the air before humidification is set to 25 ° C., for example, and the temperature of the air after humidification is set to 50 ° C., for example.

  As a first comparative example, only the cooling adsorbent is used, and the amount of the cooling adsorbent necessary for satisfying the humidification condition described above is obtained. The adsorbent for cooling has an adsorption amount of about 0.18 g / g at a temperature of 25 ° C. and an absolute humidity of 0.006 g / g (see waveform L1) before the air passes through. The cooling adsorbent has a temperature of 50 ° C. and an absolute humidity of 0.014 g / g (see waveform L2) after the passage of air, so the adsorption amount is 0.02 g. Therefore, the amount of moisture that can be humidified per 1 g of the adsorbent for cooling is 0.16 g / g because the difference between the two values is δ1 (= 0.18−0.02). Thus, the amount of the adsorbent required for cooling is about 6.3 g because it is a value obtained by dividing the required humidification amount (1 g) by the moisture amount (0.16 g / g) that can be humidified per 1 g.

  As a second comparative example, only the air-conditioning adsorbent is used to determine the amount of air-conditioning adsorbent necessary to satisfy the above-described humidification conditions. The air-conditioning adsorbent has an adsorption amount of about 0.26 g / g at a temperature of 25 ° C. and an absolute humidity of 0.006 g / g (see waveform M1) before the air passes through. Further, since the air-conditioning adsorbent has a temperature of 50 ° C. and an absolute humidity of 0.014 g / g (see waveform M3) after the passage of air, the adsorption amount is 0.20 g. Therefore, the amount of moisture that can be humidified per gram of the air-conditioning adsorbent is 0.06 g / g because the difference between the two values is δ2 (= 0.26-0.20). As a result, the necessary amount of the air-conditioning adsorbent is approximately 16.7 g because it is a value obtained by dividing the required humidification amount (1 g) by the moisture amount (0.06 g / g) that can be humidified per 1 g.

  As a third comparative example, in order to maximize the performance of the air-conditioning adsorbent using only the air-conditioning adsorbent, the temperature of the air after humidified air is set to 80 ° C., and the amount of air-conditioning adsorbent required Ask for. The air-conditioning adsorbent has an adsorption amount of about 0.26 g / g at a temperature of 25 ° C. and an absolute humidity of 0.006 g / g (see waveform M1) before the air passes through. Further, since the air-conditioning adsorbent has a temperature of 80 ° C. and an absolute humidity of 0.014 g / g (see waveform M3) after the passage of air, the adsorbed amount is 0.02 g. Therefore, the amount of moisture that can be humidified per 1 g of the air-conditioning adsorbent is 0.24 g / g because the difference between the two values is δ3 (= 0.26 to 0.02). As a result, the necessary amount of the air-conditioning adsorbent is approximately 4.2 g since it is a value obtained by dividing the required humidification amount (1 g) by the moisture amount (0.24 g / g) that can be humidified per 1 g.

  In this way, when the above three comparative examples are compared, the third comparative example requires the least amount of adsorbent, but in the third comparative example, the temperature of the humidified air is as high as 80 ° C. It is high temperature to supply humidified air.

  In the present embodiment, as described above, both the cooling module 25 having the cooling adsorbent and the adsorption module 3 having the air conditioning adsorbent are used. Accordingly, in the present embodiment, first, for example, 0.5 g is humidified out of 1 g of the humidification amount necessary to make the air passing through the air-conditioning adsorbent into humidified air, and then the cooling adsorbent is used. Then, the remaining 0.5 g of the required 1 g of humidification is humidified. In such a case, the amount of the adsorbent for cooling and the adsorbent for air conditioning is obtained.

  In the state before the air passes, the adsorbent for air conditioning has an adsorption amount of about 0.26 g / g at a temperature of 25 ° C. and an absolute humidity of 0.006 g / g (see waveform M1) as described above. In order to maximize the performance of the air-conditioning adsorbent, the air-conditioning adsorbent has a temperature of 80 ° C. after the passage of air, and the absolute humidity is approximately halfway between 0.014 g / g and 0.006 g / g. Since the value is about 0.010 g / g (see waveform M2), the adsorption amount is 0.02 g. Therefore, the amount of moisture that can be humidified per 1 g of the air-conditioning adsorbent is 0.24 g / g because the difference between the two values is δ3 (= 0.26 to 0.02). Accordingly, the necessary amount of the air-conditioning adsorbent is about 2.1 g because it is a value obtained by dividing the required humidification amount (1 g) by the moisture amount (0.24 g / g) that can be humidified per 0.5 g.

  The air humidified by 0.5 g as described above then passes through the cooling module 25. As described above, the adsorbent for cooling of the cooling module 25 is about 0.18 g / g at a temperature of 25 ° C. and an absolute humidity of 0.006 g / g (see waveform L1) as described above. It is. The cooling adsorbent has a temperature of 50 ° C. and an absolute humidity of 0.014 g / g (see waveform L2) after the passage of air, so the adsorption amount is 0.02 g. Therefore, the amount of moisture that can be humidified per 1 g of the adsorbent for cooling is 0.16 g / g because the difference between the two values is δ1 (= 0.18−0.02). As a result, the amount of the adsorbent required for cooling is about 3.1 g because it is a value obtained by dividing the required amount of humidification (1 g) by the amount of water (0.16 g / g) that can be humidified per 0.5 g.

  In the present embodiment, the total amount of the necessary adsorbent for air conditioning and the adsorbent for cooling is about 5.2 g. Therefore, as described above, the amount of adsorbent required is smaller than in the first comparative example and the second comparative example, and the air temperature after humidification can be set to 50 ° C.

  Thus, since the humidification air which passed the adsorption | suction module 3 is further humidified by the cooling module 25, the temperature of the air which passes by the latent heat of vaporization when the cooling module 25 discharge | releases a water | moisture content can be made low. As a result, the temperature of the humidified air can be adjusted.

  Next, the flow path switching unit 4 will be described. FIG. 5 is a perspective view showing the flow path switching unit 4. FIG. 6 is a side view showing the flow path switching unit 4. The dehumidifying / humidifying device 100 alternately switches the adsorption operation and desorption operation of the adsorption elements 31A and 31B of the adsorption module 3 every 5 to 10 minutes. Therefore, in the present embodiment, the humidified air is continuously blown out from the humidified air outlet 8 and the dehumidified air is continuously blown out from the dehumidified air outlet 9, as shown in FIG. The flow path switching unit 4 is disposed on the side.

  The flow path switching unit 4 is a flow path switching unit, and is configured to switch the destination of the air that has passed through the adsorption module 3 and the cooling module 25. The flow path switching unit 4 distributes the air that has passed through the first adsorption element 31A and the first adsorption unit 51A to the humidified air passage 80, and the air that has passed through the second adsorption element 31B and the second adsorption unit 51B. The state of distributing to the dehumidifying air passage 90 and the air passing through the first adsorbing element 31A and the first adsorbing portion 51A are distributed to the dehumidifying air passage 90 and passed through the second adsorbing element 31B and the second adsorbing portion 51B. The state in which air is distributed to the humidified air passage 80 is switched.

  As shown in FIG. 2, air that has passed through the first adsorption element 31 </ b> A and the first adsorption unit 51 </ b> A flows into the flow path switching unit 4 by the partition plate 40 disposed on the downstream side of the cooling module 25. It is partitioned into a first inflow space 3A and a second inflow space 3B into which air that has passed through the second adsorption element 31B and the second adsorption portion 51B flows.

  As shown in FIG. 2, the downstream side of the partition plate 40 is divided into a humidified air passage 80 connected to the humidified air outlet 8 and a dehumidified air passage 90 connected to the dehumidified air outlet 9 by a partition wall 11 formed integrally with the casing 1. The section of the humidified air passage 80 is smaller than that of the dehumidified air passage 90. Thereby, the air volume of the humidified air blown out from the humidified air outlet 8 is smaller than the air volume of the dehumidified air blown out from the dehumidified air outlet 9.

  The flow path switching unit 4 includes a plurality of flow path switching doors 6 and a shaft 60. The flow path switching door 6 is disposed between the partition plate 40 and the partition wall 11. The shaft 60 is integrally provided with the flow path switching door 6. The shaft 60 is rotatably provided along the width direction X of the casing 1.

  The shaft 60 is provided with four flow path switching doors 6, two humidifying side doors 61 a and 61 b and two dehumidifying side doors 62 a and 62 b. In order to reduce the rotation range θ (about 60 degrees in this embodiment) of the flow path switching door 6, two humidifying doors 61a and 61b and two dehumidifying doors 62a and 62b are provided. The humidifying doors 61a and 61b communicate with the humidified air passage 80 and the first inflow space 3A according to their angular positions, and block the communication between the humidified air passage 80 and the second inflow space 3B. On the contrary, the humidified air passage 80 and the second inflow space 3B are communicated with each other and the communication between the humidified air passage 80 and the first inflow space 3A is closed. Similarly to the humidifying side doors 61a and 61b, the dehumidifying side doors 62a and 62b communicate the dehumidifying air passage 90 and the first inflow space 3A in accordance with the angular positions thereof, and the dehumidifying air passage 90 and the second inflow space 3B. A state in which the communication with the dehumidifying air passage 90 and the second inflow space 3B are communicated with each other, and a state in which the communication between the dehumidifying air passage 90 and the first inflow space 3A is obstructed. Switch.

  The door areas of the humidifying doors 61a and 61b and the dehumidifying doors 62a and 62b are substantially proportional to the passage cross-sectional areas of both flow passages 80 and 90, and the dehumidifying doors 62a and 62b are large. Is getting smaller. Further, a lever plate 63 for rotating the flow path switching door 6 is provided at one end side of the shaft 60, and the lever plate 63 is configured to protrude to the outside of the casing 1. On the outer surface of the casing 1, an actuator 7 such as a servo motor that is connected to the end of the lever plate 63 and switches the flow path switching door 6 is disposed.

  Next, the operation of the flow path switching unit 4 will be described. 7 and 8 are diagrams for explaining the mechanism of channel switching, in which (a) is a sectional view taken along the line aa in FIG. 1, and (b) is a sectional view taken along the line bb in FIG. FIG. 7 shows a state in which the flow path switching unit 4 is at the first flow path switching position. FIG. 8 shows a state where the flow path switching unit 4 is in the second flow path switching position.

  When the flow path switching unit 4 is in the first flow path switching position, the humidifying side doors 61a and 61b block communication between the humidified air passage 80 and the first inflow space 3A, and the humidified air passage 80 and the second It is in a state of communicating with the inflow space 3B. The dehumidifying side doors 62a and 62b communicate with the dehumidifying air passage 90 and the first inflow space 3A, and close the communication between the dehumidifying air passage 90 and the second inflow space 3B.

  Therefore, as shown in FIG. 7A, on the humidified air outlet 8 side, the humidified air that flows out to the second inflow space 3B flows out to the humidified air outlet 8 as it is, and the dehumidified air that flows out to the first inflow space 3A is Since the flow path to the humidification air outlet 8 is closed by the humidification side door 61b, it flows in the first inflow space 3A to the other side in the width direction X (the front side in FIG. 7) and moves to the dehumidification air passage 90 side. From there, it flows out to the dehumidifying air outlet 9.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 7B, the dehumidifying air flowing out to the first inflow space 3A directly flows out to the dehumidifying air outlet 9, and the humidified air flowing out to the second inflow space 3B is dehumidified. Since the flow path to the air outlet 9 is blocked by the dehumidifying side door 62b, it flows in the second inflow space 3B in the width direction X one side (the back side in FIG. 7) and moves to the humidified air passage 80 side. From there, it flows out to the humidified air outlet 8.

  In a state where the flow path switching unit 4 is at the second flow path switching position, it is in a state opposite to the first flow path switching position described above, and the humidifying side doors 61a and 61b are connected to the humidified air passage 80 and the first flow switching position. The first inflow space 3A is in communication with the humidified air passage 80 and the second inflow space 3B. Further, the dehumidifying side doors 62a and 62b are in a state where the communication between the dehumidifying air passage 90 and the first inflow space 3A is blocked and the dehumidifying air passage 90 and the second inflow space 3B are in communication.

  Therefore, on the side of the humidified air outlet 8 in FIG. 8A, the humidified air that has flowed out to the first inflow space 3A directly flows out to the humidified air outlet 8, and the dehumidified air that has flowed out to the second inflow space 3B is 8 is closed by the humidifying side door 61a, so that it flows in the second inflow space 3B to the other side in the width direction X (the front side in FIG. 8) and moves to the dehumidifying air passage 90 side. It flows out to the dehumidifying wind outlet 9.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 8B, the dehumidifying air flowing out into the second inflow space 3B directly flows out into the dehumidifying air outlet 9, and the humidified air flowing out into the first inflow space 3A is dehumidified. Since the flow path to the air outlet 9 is closed by the dehumidifying side door 62a, it flows in the first inflow space 3A in the width direction X one side (the back side of the drawing in FIG. 8) and moves to the humidified air passage 80 side. From there, it flows out to the humidified air outlet 8.

  The control device (not shown) is a control means, and controls the blower 2, controls the current of the Peltier element 30 in the adsorption module 3, and controls the actuator 7 in the flow path switching unit 4. The control device is realized by a microcomputer, for example.

  The control device controls the flow path switching door 6 to rotate according to the reversal of the current of the Peltier element 30, and the destination of each air processed by the adsorption module 3 is one of the humidified air outlet 8 From the dehumidifying air outlet 9 to the humidifying air outlet 8. The operation timing of the flow path switching door 6 is from when the current of the Peltier element 30 is reversed until the temperature of each plate surface portion 30a, 30b of the Peltier element 30 is reversed in high and low, and usually after the reversal of the current. This is a period until a time of about 30 seconds to 60 seconds elapses. The control device can generate the dehumidified air and the humidified air more efficiently by operating the flow path switching door 6 and switching the destination after a while after the current reversal.

  Next, the operation of the dehumidifying / humidifying device 100 will be described. The dehumidifying / humidifying device 100 operates as follows, for example, in winter when the outside air is dry. The blower 2 sucks in the air in the passenger compartment and sends the air to the first adsorption element 31A and the second adsorption element 31B of the adsorption module 3, respectively. In the adsorption module 3, for example, one plate surface portion 30a of the Peltier element 30 functions as a heat absorbing portion, and the other plate surface portion 30b functions as a heat radiating portion.

  For this reason, the first adsorption element 31A is cooled by one plate surface portion 30a, the adsorption operation of the air conditioning adsorbent provided in the air conditioning fin 33 proceeds, and the moisture in the air passing through the air conditioning fin 33 To adsorb. The second adsorption element 31B is heated by the other plate surface portion 30b of the Peltier element 30, and the desorption operation of the air-conditioning adsorbent provided on the air-conditioning fin 33 of the second adsorption element 31B proceeds. Moisture is released to the air passing through the fins 33.

  The air that has been dehumidified after passing through the first adsorption element 31A of the adsorption module 3 passes through the first adsorption part 51A of the cooling module 25 and flows out to the first inflow space 3A. The first adsorbing part 51A of the cooling module 25 is cooled by the air dehumidified by the first adsorbing element 31A, and the adsorbing operation of the adsorbing material provided in the cooling fin proceeds and passes through the cooling fin. Adsorbs moisture in the air. The air that has been humidified by passing through the second adsorption element 31B of the adsorption module 3 passes through the second adsorption portion 51B of the cooling module 25 and flows out into the second inflow space 3B. The second adsorption part 51B of the cooling module 25 is heated by the air humidified by the second adsorption element 31B, and the desorption operation of the cooling adsorbent provided in the cooling fin proceeds, so that the cooling fin is removed. Releases moisture into the passing air. The air that has passed through the cooling module 25 in this way is sent to the humidified air passage 80 by the flow path switching door 6 and is blown out from the humidified air passage 80, and the dehumidified air is sent to the dehumidified air passage 90. It is turned around and blown out from the dehumidifying air outlet 9.

  Next, in the adsorption module 3, when the adsorption operation and the desorption operation are performed for a predetermined time, the voltage applied to the Peltier element 30 is reversed, and the heat absorption part and the heat dissipation part of the Peltier element 30 are switched. In other words, one plate surface portion 30a functions as a heat dissipation portion, and the other plate surface portion 30b functions as a heat absorption portion. Then, by switching the functions of the plate surface portions 30a and 30b of the Peltier element 30, the adsorption operation and desorption operation of the air-conditioning adsorbent are reversed in the adsorption elements 31A and 31B, respectively.

  Accordingly, the first adsorbing element 31A desorbs the water vapor that has been adsorbed so far by heating the air-conditioning fin 33 that has been cooled. The second adsorption element 31B starts adsorption of water vapor when the heated air conditioning fin 33 is cooled. As a result, the first adsorbing element 31A releases and vaporizes water vapor into the air passing therethrough, and the second adsorbing element 31B adsorbs and dehumidifies the water vapor in the air passing therethrough. Similarly, also in the cooling module 25, the first adsorption unit 51A releases and humidifies the water vapor to the air passing therethrough, and the second adsorption unit 51B adsorbs the water vapor in the air passing therethrough. To dehumidify. Thereby, the humidified air flows out to the second inflow space 3B, and the dehumidified air flows out to the first inflow space 3A.

  When the voltage applied to the Peltier element 30 is reversed, the flow path switching door 6 rotates from the first flow path switching position to the second flow path switching position to switch the flow path. Therefore, for example, the flow path switching door 6 is switched from the state shown in FIG. 7 to the state shown in FIG. For this reason, the air humidified by passing through the first adsorption element 31A of the adsorption module 3 flows out into the first inflow space 3A, and the air dehumidified through the second adsorption element 31B is in the second inflow space. 3B, the air that has been humidified by the flow path switching door 6 is directed to the humidified air passage 80 and blown out from the humidified air outlet 8, and the dehumidified air is directed to the dehumidified air passage 90 and is supplied to the dehumidified air outlet. 9 is blown out.

  The dehumidifying / humidifying device 100 reverses the adsorption operation and desorption operation at a certain timing in the adsorption module 3 as described above, and in accordance with this, the dehumidifying / humidifying device 100 flows through the blow-off flow path between the dehumidified air and the humidified air. Switching is performed by the road switching door 6. Thereby, the dehumidified air can be continuously blown out from the dehumidified air outlet 9, and the humidified air can be continuously blown out from the humidified air outlet 8. Then, the dehumidified air is used for anti-fogging of the window glass, and the humidified air is used for improving comfort.

  As described above, in the dehumidifying / humidifying device 100 of the present embodiment, the humidified air humidified by the adsorption module 3 passes through the cooling module 25 and passes through the humidified air passage 80 by the flow path switching unit 4. Since the first adsorbing part 51A and the second adsorbing part 51B constituting the cooling module 25 adsorb and release moisture based on the temperature of the passing air, the air humidified by the adsorbing module 3 is converted into the first adsorbing part 51B. It can be further humidified by the adsorption part 51A or the second adsorption part 51B. Since the cooling module 25 further humidifies in this way, the temperature of the air passing therethrough can be lowered by the latent heat of evaporation when moisture is released. As a result, the temperature of the humidified air can be adjusted. In addition, the present embodiment can be implemented with a simple configuration in which a cooling module 25 that is a means that does not require a drive source, that is, a means that does not need to be operated electrically and mechanically, is provided without newly providing a cooling means. The humidifier 100 can be realized.

  Moreover, in this Embodiment, the discharge | release minimum temperature of the adsorption material for an air conditioning is set based on the temperature of the surface parts 30a and 30b heated by the Peltier device 30. FIG. Therefore, the air humidified by the air conditioning adsorbent becomes equal to or higher than the lower limit discharge temperature of the air conditioning adsorbent. The adsorbent for cooling adsorbs and releases moisture based on the temperature of the air passing through it, but the adsorbent for cooling passes by making the lower limit temperature of the adsorbent for cooling lower than the lower limit temperature of the adsorbent for air conditioning. The adsorbing material for cooling can be set to the discharge lower limit temperature or higher by the humidified air. In this way, the humidified air passes through the cooling adsorption unit, so that the cooling adsorption unit is warmed, the moisture adsorbed by the cooling adsorption unit is released, and the humidified air can be reliably cooled.

  Moreover, in this Embodiment, the air dehumidified with the air-conditioning adsorbent becomes below the adsorption upper limit temperature of the air-conditioning adsorbent. The adsorbing material for cooling adsorbs and releases moisture based on the temperature of the air passing therethrough, but the dehumidifying gas passing therethrough is made lower by setting the upper limit temperature of the adsorbing material for cooling lower than the upper limit temperature of the adsorbing material for air conditioning. The cooling adsorbent can be made to be below the upper limit adsorption temperature by the wind. In this way, the dehumidified air passes through the cooling adsorbent, so that the cooling adsorbent is cooled, and the cooling adsorbent can be further adsorbed by moisture. Thereby, it can be set as the dehumidification wind with little water | moisture content.

  Moreover, in this Embodiment, since the 1st adsorption | suction part 51A and the 2nd adsorption | suction part 51B are thermally insulated by the heat insulator 50, even if it is a case where humidified air passes through one adsorption | suction part, the other adsorption | suction It is possible to prevent the portion from being heated based on the humidified air. Accordingly, the cooling adsorbent can adsorb and release moisture based on the temperature of the humidified or dehumidified air passing therethrough. By using the heat insulator 50 as described above, it is easy to adjust the temperature at which the cooling adsorbent can exhibit a desired dehumidifying / humidifying function.

  Moreover, in this Embodiment, as demonstrated in relation to FIG. 4, the total amount of the adsorbent for air conditioning required and the adsorbent for cooling can be decreased. Thereby, even if it is the structure provided with the adsorption | suction module 3 and the two cooling modules 25, the dehumidification / humidification apparatus 100 can be reduced in size.

  Further, the dehumidifying / humidifying device 100 of the present embodiment is formed in a flat, substantially rectangular parallelepiped box shape in which a thickness portion corresponding to the height is designed to be thin so as to be suitable for installation on a ceiling in a vehicle interior. Thus, since the dehumidifying / humidifying device 100 has a thin shape, the ceiling portion of the vehicle can also be embedded. Accordingly, the dehumidifying / humidifying device 100 can be provided in the vehicle without eroding the internal space for the passenger of the vehicle.

  Further, since the dehumidifying / humidifying device 100 has a thin shape, the humidified air passage 80 and the dehumidified air passage 90 provided by being divided in the thickness direction can be formed thin. As a result, the humidified air passage 80 and the dehumidified air passage 90 can be routed by being embedded in a ceiling portion in the vehicle up to a desired location.

  Further, since the only part of the dehumidifying / humidifying device 100 that needs to be supplied with power is the multi-blade fan 2 and the adsorption module 3, the dehumidifying / humidifying device 100 can be controlled by being provided in the vehicle without using complicated electrical wiring. . Further, by reducing the thickness dimension of the multiblade fan 2, the dehumidifying / humidifying device 100 can be designed to be thin.

  In this embodiment, a pair of fixed adsorbing elements 31A and 31B provided with an air-conditioning adsorbing material are directly arranged on the plate surface portions 30a and 30b that function as heat absorbing portions and heat radiating portions of the Peltier element 30, respectively. The adsorption module 3 is configured. The adsorption module 3 functionally replaces the heat absorption part and the heat dissipation part by reversing the current flowing to the Peltier element 30, switches the cooling and heating for the adsorption elements 31A and 31B, and reverses the adsorption operation and the desorption operation. The path switching door 6 is used to switch the destination of the air that has passed through the first adsorption element 31A and the air that has passed through the second adsorption element 31B according to the reverse of the adsorption operation and the desorption operation.

  Accordingly, the dehumidifying / humidifying device 100 does not need to be provided with a rotation driving unit as in the adsorption rotor system, and the adsorption elements 31A and 31B are directly arranged on the Peltier element 30 to heat and cool the adsorption elements 31A and 31B. Since the thermal conductivity between the Peltier element 30 and the adsorption element is high, the adsorption elements 31A and 31B and the Peltier element 30 can be further downsized. As a result, the apparatus configuration can be simplified and the entire apparatus can be further reduced in size.

  Further, the flow path switching unit 4 can switch the destination of each air by rotating by the actuator 7. Therefore, since the channel switching can be realized with a simple configuration, the channel switching unit 4 can be miniaturized.
