[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating toilet seat and a heating toilet seat device. More specifically, the present invention relates to a heating toilet seat that reduces heat radiation from the toilet seat surface when not in use, and a heating toilet seat device that includes a toilet seat cover on the heating toilet seat and starts toilet seat heating without operating a switch.
[0002]
[Prior art and its problems]
Various heating toilet seats with improved energy saving effects have been proposed. For example, Japanese Patent Laid-Open No. 11-309089 discloses a toilet seat provided with a toilet seat cover (toilet lid) having a hollow portion inside a heating toilet seat in which a heat storage material is arranged on the upper surface or the lower surface of a heater unit installed in the toilet seat. An apparatus is disclosed. This toilet seat device stores heat in the nighttime zone where power demand is small and inexpensive, and warms the toilet seat by heat radiation of the heat storage material during the daytime. Moreover, since the hollow part is provided in the toilet seat cover, there is little heat radiation from the toilet seat cover, and energy saving can be achieved.
[0003]
However, although the heat insulating effect by the toilet seat cover is recognized to some extent, the air layer between the toilet seat cover and the toilet seat is also connected to the toilet side, and heat diffusion from the toilet seat surface due to convection cannot be sufficiently prevented, resulting in energy loss. It was.
[0004]
On the other hand, Japanese Patent Laid-Open No. 11-87953 discloses a toilet seat device including a toilet seat sealing portion formed in a shape that forms a sealed space together with the upper surface of the toilet seat. In this toilet seat device, since a sealed space is formed on the upper surface of the toilet seat when not in use, heat diffusion from the surface of the toilet seat is reduced, and heat dissipation when not in use can be reduced to save energy.
[0005]
However, in any of these toilet seat apparatuses, heat dissipation from the toilet seat surface is hardly taken into consideration, and energy loss due to forgetting to close the toilet seat cover or the toilet seat sealing portion is large.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic configuration diagram of a heating toilet seat device A according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional configuration diagram showing an embodiment of a heating toilet seat 1 used in the heating toilet seat device A. A heating toilet seat device A shown in FIG. 1 includes a heating toilet seat 1, a toilet seat cover 2 that covers the seating surface 18 of the toilet seat body 11 of the heating toilet seat 1, an open / close detection means 5 that detects opening and closing of the toilet seat cover 2, and the toilet seat cover. And a control unit 3 that detects the opening and closing of the heating toilet 1 and controls the supply and exhaust of the heating toilet seat 1.
[0021]
The heated toilet seat 1 includes a hollow toilet seat body 11, a gas contraction chamber 12 that expands by air supply when not seated, and contracts so that the inner surfaces are almost in close contact with each other when seated, and a radiator 20 that warms the toilet seat surface 18. And an air supply / exhaust means 4 for supplying and exhausting the gas contraction chamber 12.
[0022]
The toilet seat body 11 is formed in a hollow shape from a seating member 11a serving as a seating surface 18 and a bottom member 11b placed on the toilet bowl. The toilet seat body 11 is made of a heat-resistant hard plastic so as to be able to withstand the load at the time of sitting, but a material having relatively good thermal conductivity is preferably used in consideration of the temperature rise at the time of sitting.
[0023]
In the toilet seat body 11, a heat dissipating body 20 serving as a heat source for warming the seating surface 18 and a gas contraction chamber 12 for controlling heat dissipation from the heat dissipating body 20 to the seating surface 18 are provided. In the heating toilet seat 1 shown in FIG. 2, the gas contraction chamber 12 is made of a resin bag 13 and is exhausted so that the inner surface is almost in close contact when exhausted. In addition, the gas contraction chamber 12 is arranged so that the heat radiating body 20 contacts the back surface of the seating surface 18 via the bag 13 (gas contraction chamber 12). For this reason, the bag body 13 is partly joined to the back surface of the seating surface 18 by, for example, an adhesive having a good heat transfer property, and the heat sink 20 is brought into contact with the back surface of the seating surface 18 at the joining position. Heat conduction from the body 20 to the seating member 11a is ensured.
[0024]
The gas contraction chamber 12 expands when a gas such as air is sent from the air supply / exhaust means 4 such as an air pump, and forms a heat insulation layer between the heat radiator 20 and the seating member 11a. Further, when the gas inside is discharged, the gas contraction chamber 12 is contracted and the inner surfaces are almost in close contact with each other, and the radiator 20 and the seating member 11a are in contact with each other through the gas contraction chamber 12. That is, the gas contraction chamber 12 controls the heat dissipation from the radiator 20, and if the inside of the gas contraction chamber 12 is exhausted and the gas contraction chamber 12 contracts, two resin films are interposed and the radiator 20 and the seating member 11 a. And the seating surface 18 is warmed, and if the gas contraction chamber 12 expands, the heating of the seating surface 12 stops. The material of the bag 13 is not particularly limited as long as it is made of resin, but a thin film and durable against expansion and contraction is preferably used, and rubber or the like can be used in consideration of expansion and contraction of the gas contraction chamber. Somewhat elastic is preferably used. The air supply / exhaust means 4 is provided, for example, in an installation box 8 for installing the toilet seat body 11 to a toilet bowl, and is connected to the gas contraction chamber 12 by an air supply / exhaust pipe 19.
[0025]
The heat radiator 20 includes a heater 22, a heat storage material 21 disposed on the seating surface 18 side of the heater 22, and a heat insulating material 23 disposed on the side surface opposite to the seating surface 18 of the heater 22. The heat storage material 21 temporarily stores heat from the heater 22 and repeats heat storage and heat dissipation. The material of the heat storage material 21 is not particularly limited, but is preferably one that has an excellent heat dissipation effect when in contact with the seating member 11a. In addition, a bag in which a heat storage material such as calcium chloride, sodium sulfate, sodium thiosulfate, polyethylene glycol, or paraffin is wrapped can be used.
[0026]
The heating toilet 1 is provided with a power supply unit (not shown) in the installation box 8 to control power supply to the heater 22. The power supply unit has, for example, a timer unit, and controls to automatically energize at night and to stop energization at daytime. Or you may make it energize so that the emitted-heat amount may be suppressed compared with the time of the night at the time of daytime, and also may carry out manual stop of energization. Thus, the heat stored in the heat storage material 21 by cheap electric power is used for heating the seating member 11a. Of course, the energization may be automatically controlled according to the heat storage amount.
[0027]
The air supply / exhaust means 4 is controlled by the control unit 3 and exhausts the gas in the gas contraction chamber 12 when sitting, and supplies the gas into the gas contraction chamber 12 when standing. That is, when seated, the air supply / exhaust means 4 is turned on, and the gas is exhausted until the inner surfaces of the bag bodies 13 stick together to form a thin film. Thus, at the time of sitting, the heat storage material 21 and the back surface of the seating member 11a come into contact with each other through the gas contraction chamber 12 (bag 13), and the seating surface 18 is warmed by the heat radiation of the heat storage material 21 (FIG. 2A). On the other hand, when standing, the air supply / exhaust means 4 is turned on again, and gas is supplied until the bag 13 swells and the radiator 20 is sufficiently separated from the back surface of the seating member 11a. In this way, the heat insulation layer by gas is formed and the heat dissipation from the heat storage material 21 is stopped (FIG. 2B).
[0028]
Thus, the air supply / exhaust means 4 starts the exhaust operation by turning on the switch when sitting, and starts the air supply operation by turning on the switch again when standing, but in the heating toilet seat device A shown in FIG. The operation of the air supply / exhaust means 4 is controlled by detecting the opening / closing of the toilet seat cover 2. That is, in the heating toilet seat device A, the toilet seat cover 2 is supported by the rotary shaft 6 for opening and closing together with the toilet seat body 11, and the open / close detection means 5 such as a limit switch provided on the rotary shaft 6 detects the opening and closing of the toilet seat cover 2. is doing. When the toilet seat cover 2 is opened, the control unit 3 detects the detection signal (opening operation) of the open / close detection means (limit switch) 5 and starts the exhaust operation of the air supply / exhaust means 4. When the toilet seat cover 2 is closed, the control unit 3 detects the detection signal (closing operation) of the open / close detection unit 5 and starts the supply of air to the air supply / exhaust unit 4. Thus, the start / stop of toilet seat heating is controlled without manual switch operation.
[0029]
Further, a temperature sensor 7 is provided in the vicinity of the seating surface 18 of the toilet seat body 11, and the temperature of the seating surface 18 is detected. The controller 3 controls the air supply / exhaust means 4 so that the temperature of the seating surface 18 becomes a constant temperature near the body temperature according to the detected temperature. More specifically, if the seating surface temperature tends to be higher than the body temperature in the in-use state where the gas contraction chamber 12 is contracted, the control unit 3 starts the air supply operation of the air supply / exhaust means 4. The gas contraction chamber 12 is slightly inflated. Then, the heat radiation from the radiator 20 to the seating surface 18 is suppressed, and the temperature of the seating surface 18 decreases. Further, if the seating surface 18 temperature tends to be lower than the body temperature during use, the exhaust operation is started to contract the gas contraction chamber 12 to bring the radiator 20 and the seating member 11a into contact with each other. Then, heat is radiated from the radiator 20 and the temperature of the seating surface 18 rises. In this way, the seating surface 18 can be kept at a constant temperature.
[0030]
As described above, according to the heating toilet seat 1 of the present invention, heat is radiated from the radiator 20 to the seating member 11a only when seated, and the seating surface 18 is warmed. Further, when not in use, there is almost no heat radiation from the toilet seat surface, and the energy loss from the toilet seat surface is greatly reduced if the toilet seat cover 2 is forgotten to close.
[0031]
FIG. 3 is a schematic cross-sectional configuration diagram of the heating toilet seat 1 according to the second embodiment. The gas contraction chamber 12 in the heating toilet seat 1 is composed of the resin film 14 and the back surface of the seating member 11a, the periphery of the resin film 14 being joined to the back surface of the seating member 11a by a heat-resistant adhesive or the like. It is only different from the first embodiment. Thus, since the gas contraction chamber 12 is constituted by the resin film 14 without using the bag 13, the heat storage material 21 and the seating member 11 a come into contact with each other through the single resin film 14. , Heat transfer is improved, energy loss is reduced, and responsiveness is improved. Further, the material cost can be reduced as compared with the case where the bag 13 is used, and the manufacturing cost can be reduced.
[0032]
FIG. 4 is a schematic cross-sectional configuration diagram of the heating toilet seat 1 according to the third embodiment. In the heating toilet seat 1, the periphery of the resin film 14 is joined to the back surface of the seating member 11a through a heat insulating material 15 such as a foam material. For this reason, the amount of heat dissipated through the resin film 14 is reduced regardless of whether the user is seated or not, and further energy saving is achieved.
[0033]
FIG. 5 is a schematic sectional view of a heating toilet seat 1 according to the fourth embodiment. In the heating toilet seat 1, a heat insulating boundary portion 16 made of a heat insulating material is provided on the seating surface 18 side of the seating member 11 a along the outer periphery of a region in contact with the gas contraction chamber 12, and when the gas contraction chamber 12 contracts. It is separated into a main seating surface 18a that contacts the heat storage material 21 and a seating surface 18b in another region. That is, in the example shown in FIG. 5, the bag 13 is joined to the back surface of the main seating surface 18a. When the gas contraction chamber 12 is constituted by the resin film 14 and the seating member 11a as in the second embodiment, the periphery of the resin film 14 is joined to the back surface of the heat insulating boundary portion 16. For example, as shown in FIG. 6, the main seating surface 18 a is formed in a region (contact region with the buttocks) where most people are supposed to sit when an adult is seated. In addition, the dashed-dotted line shown in FIG. 6 shows a person's seating position. Therefore, heat transfer to other than the main seating surface 18a is blocked by the heat insulating boundary portion 16, and only the region is quickly warmed. In this way, not only does the responsiveness at the time of seating feel faster when seated, but also wasteful heat dissipation from other areas is reduced.
[0034]
Since the heat insulating boundary 16 is used to separate the main seating surface 18a and other regions as described above, it is provided with a predetermined width from the front side or the back side of the seating surface 18 in a band shape with a constant width, Preferably, it is formed so as to penetrate through the seating member 11a with the same thickness as the seating member 11a. The heat insulating boundary portion 16 may be formed by insert-molding a heat insulating material so as to be integrally formed with the seating member 11a or a structure in which the main seating surface 18a and the heat insulating material can be assembled separately as separate parts.
[0035]
Even when the gas shrinkage chamber 12 is formed using either the bag 13 or the resin film 14, the resin film 14 and the bag 13 are joined in a region wider than the main seating surface 18a, for example, as shown in FIG. The gas contraction chamber 12 may be formed as in the fifth embodiment. Also in this case, it is the back surface of the main seating surface 18a that is in contact with the heat storage material 21, and the main seating surface 18a is quickly warmed to suppress heat dissipation from other regions.
[0036]
However, when the heat insulating boundary 16 is provided by the heat insulating material 23 as in the fourth embodiment, the seating surface 18b other than the main seating surface 18a is hardly warmed and moves the buttocks (especially a toilet seat with a cleaning function) When the cleaning mechanism is activated, the coldness will be felt. Therefore, in the fifth embodiment, the heater 22 is disposed in a wider range than the region where the heat storage material 21 is disposed, and the peripheral portion of the heater 22 that protrudes from the region where the heat storage material 21 is disposed is joined to the resin film 14. That is, in the fifth embodiment, the gas contraction chamber 12 is formed in a region wider than the main seating surface 18a, and when the gas contraction chamber 12 contracts, the heat storage material 21 contacts the back surface of the main seating surface 18a. The heater 22 in a range wider than the region where the heat storage material 21 is disposed warms the seating surface 18b around the main seating surface 18a. Accordingly, even if the hips are moved out of the main seating surface 18a, there is no feeling of coldness.
[0037]
FIG. 8 is a schematic cross-sectional configuration diagram of the heating toilet seat 1 according to the sixth embodiment. In the heating toilet seat 1, the thickness of the seating member 11a on the main seating surface 18a is thinner than the thickness of the seating member 11a on the seating surface 18b in the other region. That is, the heat capacity in the region of the main seating surface 18a is small, and the heat from the heat storage material 21 quickly spreads over the main seating surface 18a.
[0038]
FIG. 9 is a schematic sectional view of a heating toilet seat 1 according to the seventh embodiment. In the heating toilet seat 1, the heating toilet seat 1 according to the fifth embodiment shown in FIG. 7 is provided with a damper 17 that lifts the main seating surface 18 a when not seated. The main seating surface 18a is separated from the seating surface 18b in the other region and is completely separated. Below the periphery of the main seating surface 18a, in order to support the damper 17, a support portion 18c that is integrally extended in a substantially L shape from the lower surface of the seating surface 18b in the other region is provided. The damper 17 is provided as if it is sandwiched between the support portion 18c and the main seating surface 18a. The damper 17 supports the main seating surface 18a in a lifted state when not seated, and other regions by the human load when seated. The main seating surface 18a is lowered so that there is almost no difference from the seating surface 18b. The damper 17 is made of, for example, a rubber member, and is disposed so that there is no gas leakage from the gas contraction chamber 12. Furthermore, the heat insulation boundary part 16 which consists of heat insulating materials is formed in the boundary of the seating surface 18b and the main seating surface 18a of another area | region.
[0039]
In this heated toilet seat 1, when a person tries to sit down, the damper 17 extends and the main seating surface 18a is lifted as shown in FIG. 10 (a). The contraction chamber 12 contracts and the damper 17 contracts, and the heat storage material 21 contacts the back surface of the main seating surface 18a. Moreover, the heater 22 arrange | positioned around the thermal storage material 21 contacts the back surface of the seating surface 18b of another area | region. When the seating is completed, the main seating surface 18a is lowered to a position where there is no step with the seating surface 18b in the other region as shown in FIG. In addition, the dashed line shown in each figure shows the position of the buttocks. Thus, in this heated toilet seat 1, first, the main seating surface 18a that contacts the human buttocks is warmed by the heat dissipation of the heat storage material 21, and when the seating is finished, the seating surface 18b around the main seating surface 18a. Is heated by the heater 22. Therefore, at the moment of sitting, only the warmed main seating surface 18a is touched, and even if the buttocks move and touch the seating surface 18b other than the main seating surface 18a when sitting down, the coldness is not felt.
[0040]
Thus, in the heated toilet seat 1 of the present invention, the seating surface 18 is warmed only during use, and heat dissipation from the seating surface 18 is suppressed when not in use. In particular, when not in use, since a heat insulation layer is formed between the heat storage material 21 and the seating surface 18 (the seating member 11a), the amount of heat radiation is remarkably suppressed, and a heating toilet seat with a high energy saving effect is provided. Moreover, it is only necessary to energize and store heat only when there is no heat stored in the heat storage material 21. For example, if heat is stored when the electricity rate in the nighttime is low, running cost is reduced, and the balance of power demand day and night is improved. Can also contribute.
[0041]
Next, the heating toilet seat apparatus B shown in FIG. 11 will be described. The heating toilet seat apparatus B includes a heating toilet seat 1 shown in FIG. 2 and a toilet seat cover 2, a driving device 10 that opens and closes the toilet seat cover 2, and a human detection sensor 9. The drive device 10 is composed of, for example, a pump device, and not only opens and closes the toilet seat cover 2 but also serves as the air supply / exhaust means 4. Further, the control unit 3 detects the sensor signal from the human detection sensor 9 and controls the driving device 10. That is, when the human detection sensor 9 detects the approach of a person, the control unit 3 drives the driving device 10 to open the toilet seat cover 2 and exhausts the gas contraction chamber 12. If the gas contraction chamber 12 is exhausted and contracts, the heat storage material 21 and the seating member 11a come into contact with each other and the seating surface 18 is warmed. When the human detection sensor 9 detects that the person is moving away, the driving device 10 is driven again to close the toilet seat cover 2 and supply air to the gas contraction chamber 12. When the gas contraction chamber 12 is supplied with air and expands, the heat storage material 21 is separated from the seating member 11a and heat dissipation is stopped. Thus, since the person detection sensor 9 is provided, toilet seat heating is started just by approaching a person, and the seating surface 18 is warmed to an appropriate temperature when sitting. In addition, toilet seat heating is stopped simply by leaving and useless toilet seat heating is prevented. Moreover, the toilet seat cover 2 is automatically opened and closed, which is extremely convenient. Also, structurally, the drive mechanism of the air supply / exhaust means 4 and the toilet seat cover 2 is sufficient as a single device, the configuration of the entire device is simplified, and the cost can be reduced.
[0042]
The toilet seat cover 2 is not limited to the shape described in the above publication, but may have a simple structure with a single lid covering the entire toilet seat body 11. This is because the heating toilet seat 1 of the present invention reduces the energy loss when the toilet seat cover 2 is forgotten to be closed, and can be without the toilet seat cover 2. Further, in the heating toilet seat device described as the embodiment, the toilet seat cover 2 is provided with a function of a switch for starting and stopping the toilet seat heating. For example, a remote control can be provided with a switch mechanism that sometimes performs an exhaust operation. In addition, a limit switch may be provided on the lower surface of the toilet seat body, and heating may be started simultaneously with the seating. For example, in the case of the configuration of the sixth embodiment, the seating surface 18 is immediately warmed, so Absent.
[0043]
【The invention's effect】
The heated toilet seat according to claim 1, wherein the seat is inflated by air supply when not seated, and contracts so that the inner surfaces are in close contact with each other by exhaust when seated, and the toilet seat body when the gas contraction chamber contracts A heat storage material disposed so as to be in contact with the back surface of the seating surface via the gas contraction chamber, a heater disposed in contact with a surface opposite to the gas contraction chamber side of the heat storage material, and the gas contraction chamber Since the air supply / exhaust means for supplying and exhausting air is provided, the seating surface is warmed only during use, heat dissipation from the seating surface is suppressed when not in use, and energy loss when not in use can be greatly reduced. Further, no energy loss occurs regardless of forgetting to close the toilet seat cover, and it is possible to provide a heating toilet seat with high energy saving effect even without the toilet seat cover.
[0044]
In addition, since heat is supplied from the heat storage material to the seating surface, if it is supplied to the heat storage material at a time when the electricity rate is low, such as at night, the running cost will be reduced. It can also contribute to the improvement of power demand imbalance.
[0045]
At this time, in the heating toilet seat according to claim 3, the gas contraction chamber is constituted by a resin bag, and in the heating toilet seat according to claim 4, the periphery of the resin film is joined to the back surface of the seating surface. Thus, the contact between the heat storage material and the back surface of the seating surface can be controlled with a relatively simple configuration. In particular, in the latter configuration, since the contact between the heat storage material and the back surface of the seating surface involves only one resin film, the material cost is reduced and the seating surface is quickly warmed. In this case, useless energy loss can be further suppressed by bonding the periphery of the resin film to the back surface of the seating surface via a heat insulating material.
[0046]
Further, in the heating toilet seat according to the fifth aspect, since the heat insulating material is provided on the surface opposite to the seating side surface of the heater, wasteful heat radiation from the heat storage material can be suppressed, and the energy saving effect is further enhanced.
[0047]
Further, in the heating toilet seat according to claim 6, when the gas contraction chamber contracts, a heat insulating boundary part that separates the main seating surface that the heat storage material contacts via the gas contraction chamber and the seating surface of the other region is formed.

[0049]
Furthermore, in the heating toilet seat according to claim 8, since the seating surface thickness of the main seating surface is thinner than the seating surface thickness of other regions, the heat capacity of this portion is reduced, and the main seating surface is quickly warmed and cooled. You can sit without feeling.
[0050]
The heating toilet seat according to claim 9 is the heating toilet seat according to claim 7 or 8, further comprising a damper in which the main seating surface is divided from the seating surfaces of other regions, and the main seating surface is lifted when not seated.
