Description

  The present invention is not only in a state of being separated from the humidifier body, but can be filled with water freely through the water inlet at the upper part of the water tank as it is connected. An upper position sensor is provided separately, and the operation of the heater and vibrator for heating the atomizing water and the heater for heating the water to an appropriate temperature can be controlled automatically according to the water level of the atomizing tank. The present invention relates to a water supply type humidifier.

  Humidifiers are household electrical appliances that humidify indoor air that is hot and dry, especially in winter, so that the indoor environment can be maintained comfortably. A sound wave type, a fan type, and a composite type in which the advantages of each of these are mixed are known.

  A heating humidifier heats water with a heater or electrode rod to generate steam, and an ultrasonic humidifier ultrasonically vibrates a vibrator located in water with an electrical signal of a specific frequency generated through an electric circuit. Each type of humidifier can be submerged in the air according to each specific method, such as atomizing water using a fan generated by rotating the fan installed on the water surface at high speed. Will supply moisture.

  Of the various humidifiers that humidify the air by the various methods described above, the ultrasonic humidifier most widely used in each home will be described as follows.

  As shown in FIG. 1, an ultrasonic humidifier (hereinafter referred to as “humidifier”) includes a main body 11 in which a spraying device (not shown) is incorporated, and a water tank that sits on one side of the upper surface of the main body 11. 12, an injection pipe 13 through which atomized water is injected, and a cover that covers the entire upper surface of the main body 11 in a state where the water tank 12 and the injection pipe 13 are seated.

  At this time, the injection pipe 13 can be integrally formed with the water tank 12, and can also serve as a cover while the outer peripheral surface of the water tank 12 is exposed as it is without a cover.

  The water tank 12 is provided with an inlet I for filling water on its bottom surface, a lid C is detachably coupled to the inlet I, and a needle valve V operated by a spring at the center of the lid C. The water supply and atomization process is as follows.

  If the water tank 12 is placed in the water tank seating groove G on one side of the upper surface of the main body 11, the needle valve V provided at the center part of the lid C of the water tank 12 with the protrusion E at the center of the seating groove G is connected to the water tank 12. By pushing up inside, the water in the water tank 12 flows into the seating groove G while the needle valve V is opened, and the water is provided in the vibrator 11A from the seating groove G through the channel F on the upper surface of the main body 11. After flowing into the atomized tank G ′, the water atomized by the vibrator 11 </ b> A is dispersed in the air outside the humidifier through the injection pipe 13.

  Reference numeral “S” is a water level sensor. When there is no water in the atomizing tank G ′, this is detected and the power input to the vibrator 11A is cut off.

  The conventional ultrasonic humidifier as described above is a lower water supply type in which the inlet I is provided on the bottom surface of the water tank 12, but when the water tank 12 runs out of water, the water tank 12 is always separated from the seating groove G. Then, there is an inconvenience that the water tank 12 cannot be filled with water without opening the inlet I with the water tank 12 returned.

  That is, when the water tank 12 is lifted, the needle valve V is closed by the spring. If the water tank 12 is not returned and the lid C is not separated with the needle valve V closed, the inlet I can be filled with water. However, there is a disadvantage that water cannot be replenished when the water tank 12 is seated on the main body 11.

  In order to eliminate the inconvenience of water injection as described above, a water tank for a humidifier having a new structure is being developed. 'And' the water replenishment structure of the water tank of the humidifier are each posted.

  The above two utility models are upper water supply type humidifiers having a water inlet provided on the upper surface of the water tank, and have the advantage that water can be injected into the water tank while the water tank is seated on the body of the humidifier. .

  However, in the registered utility model No. 359947, the grounding sensor and the microcomputer, which are important components for detecting the opening and closing of the lid provided at the water tank inlet, are not shown on the sectional view. The exact operation effect is not known, and the water tank is generally separable from the humidifier body for cleaning, etc., but the connection between the ground sensor and the microcomputer built in the body is a contact type Therefore, malfunctions associated with poor contact can be caused by repeated use over a long period of time.

  That is, the registered utility model No. 359947 has a structure in which a water tank is simply filled with water because the water tank is provided with a ground sensor, and the ground sensor is considerably damaged in cleaning. Not only is it cumbersome to pay attention to, but it also has the disadvantage of requiring management of the contact area so that the contact connection between the ground sensor and the microcomputer can be maintained.

  A sensor is provided at the water tank inlet. After the water tank is filled with water, the lid is closed and the electronic open / close valve is opened while the sensor is activated. When water flows into the humidification tank (or atomization tank) through the electronic open / close valve, the humidifier does not work unless the lid is closed after the water tank is filled with water. That is, the lid must be closed after filling the water tank.

  The above registered utility model No. 359948 has a structure in which the interior space of the water tank is separated into upper and lower rooms by a separator, and the upper and lower rooms are connected by a vertical pipe line to which a water regulating flow member is coupled. When the water adjustment flow member is manually rotated to supply water to the humidifier body by flowing the water in the upper room into the lower room, the water adjustment flow member must be supplied one by one each time water supply is required. There is a hassle that you have to rotate.

  The present invention has been devised in order to solve various problems of conventional lower water supply type or upper water supply type humidifiers. The structure of the water tank is simple, and the water tank is removed from the humidifier body. In addition to being able to inject water into the water tank without separation, normal atomization is possible even without closing the water tank lid so that the water can be heated to an appropriate temperature and the heater is activated. An object of the present invention is to provide an upper water supply type humidifier capable of controlling the water level sensor with a water level sensor.

  The above-described object of the present invention can be achieved by a pair of water level sensors for detecting the water level step by step and a sealing structure for the bottom water supply port of the water tank.

  The upper water supply type humidifier of the present invention is an ultrasonic type humidifier, in which the water tank is coupled to the humidifier body, not to inject water into the water tank, but after injecting water, the lid of the water tank is not closed. Normal operation of the humidifier is possible even in the state, with a water supply from the elutriator according to the water level of the atomization tank where the water is atomized by the vibrator, a heater for heating the water to an appropriate temperature, and water fog Even the operation of the vibrator to be converted is automatically controlled by the water level sensor.

  As described above, the upper water supply type humidifier according to the present invention improves the operation accuracy because the operation of the heater and the vibrator and the water supply are automatically performed by the pair of water level sensors, and the water supply port and the sealing are improved. Even when the lid of the water tank is opened due to the coupling structure of the members, the humidifier can be operated normally without water overflow and water can be injected into the water tank.

  The upper water supply type humidifier of the present invention as described above has structural features in the pair of water level sensors provided in the atomization tank and the bottom water supply port sealing structure of the water tank as compared with the conventional upper water supply type humidifier. Each of them is described as follows.

  The pair of water level sensors includes a water supply sensor for controlling an electronic open / close valve that allows water to flow into or from the water tank to the atomization tank, and water flowing into the atomization tank at a temperature of less than 100 ° C. And a heater / vibrator operating sensor for controlling the operation of a vibrator for atomizing water and a heater for atomizing water.

  At this time, each water level sensor stands on the bottom of the atomization tank, and the post-shaped outer peripheral surface of the post is moved upward and downward by the water level in the state that the central part is penetrated by the post with the switch built in the inside. When the float is in the proximity of the float, the switch inside the post is turned on / off.

  Of the above two sensors, the water supply sensor serves to control the opening / closing of the electronic open / close valve coupled to the flow path connected from the water tank to the atomization tank by the water level. The operation sensor serves to turn on / off a heater and a vibrator for heating water flowing into the atomization tank depending on the water level.

  As described above, the two sensors for controlling the operation of the electronic opening / closing valve and the heater / vibrator according to the water level are different in the position of the highest point and the lowest point of each float locus. Where the water level detection height increases in the order of float lowest point → float lowest point of heater / vibrator actuation sensor → heater / vibrator actuation sensor float highest point → electronic open / close valve actuation sensor float highest point The operation of the two sensors will be described as follows.

  Since there is no water in the atomization tank, when the floats of the two sensors are all at the lowest point, the heater and vibrator are in a stopped state, but the electronic opening and closing of the flow path connected to the atomization tank from the water tank When the valve is in an open state and the water tank is filled with water, the water in the water tank flows into the atomization tank through the opened electronic opening / closing valve.

  When the water flows in, the float of the two sensors rises together with the electronic open / close valve being continuously opened. The float of the heater / vibrator operating sensor is at its lowest point. The vibrator and the heater are operated by moving up from the position.

  Of the two floats that rise together, the heater / vibrator actuation sensor float reaches the highest point first, but the electronic open / close valve actuation sensor float reaches the highest point. When there is no state, the water of the water tank is continuously supplied to the atomization tank through the electronic opening / closing valve.

  By continuously supplying water to the atomization tank, the float of the sensor for operating the electronic open / close valve reaches its highest point while the float of the heater / vibrator operating sensor maintains the highest point. If the float of the sensor for operating the electronic opening / closing valve reaches the highest point, the water supply is interrupted while the electronic opening / closing valve is closed.

  That is, during normal operation of the humidifier, the heater / vibrator activation sensor float will maintain the highest point, and the water will be atomized and sprayed outside the humidifier to operate the electronic open / close valve. The electronic open / close valve is repeatedly opened and closed while the float of the sensor moves between its highest point and the immediate lower part close to the highest point.

  When the water supply to the atomization tank is stopped even though the electronic open / close valve is in an open state because there is no water in the water tank, water is injected to cause the electronic open / close valve operation sensor to After the float is initially lowered alone, both the float of the sensor for operating the electronic opening / closing valve and the float of the heater / vibrator sensor are lowered, and the float of the heater / vibrator sensor is at the lowest point. By reaching, the operation of the heater / vibrator is stopped.

  At this time, the float of the sensor for operating the electronic opening / closing valve cannot reach the lowest point and maintains the same height as the float of the sensor for operating the heater / vibrator. This is because water does not decrease due to atomization while stopping, and if the water level becomes low due to natural evaporation or the like, the float of the sensor for operating the electronic on-off valve can be further lowered.

  That is, the heater / vibrator is stopped with water remaining in the atomization tank, and of course, the electronic opening / closing valve is kept open.

  In addition, the pair of sensors can be integrated into one sensor, but both the electronic open / close valve operation switch and the heater / vibrator operation switch can be incorporated in the post.

  In the above case, the electronic on / off valve operating switch coupled to the inside of the post should be coupled to the upper part, and the heater / vibrator operating switch should be coupled to the lower part, which corresponds to the moment when the electronic on / off valve is closed. This is because the heater / vibrator cannot be operated stably unless the highest water level of the atomization tank is set higher than the highest float position of the heater / vibrator operating sensor.

  However, a single post structure in which a pair of sensors or two switches are both incorporated is not adopted, and a single post structure in which only one switch is incorporated, as in a conventional general humidifier, may be applied. In such a case, it is desirable to use a microcomputer with a built-in control circuit in such a case.

  In other words, a water level sensor with only one switch is used as a heater / vibrator operation sensor, and after a certain time has elapsed after the heater / vibrator is activated by the heater / vibrator sensor, the electronic open / close valve is closed. The operation can be controlled by the microcomputer in time, and by controlling the time from when the vibrator is activated to when the electronic open / close valve is closed, it is above the maximum water level of the vibrator operation sensor float. The amount of water supplied can be adjusted.

  Of course, if the water level of the atomization tank is lowered by atomization and the heater / vibrator sensor detects the lowest point, the electronic stop valve is opened and the vibrator stops after a certain time has passed. .

  However, if water is supplied through an electronic valve opened within a certain time, the water level in the atomization tank increases, and if the heater / vibrator sensor detects the highest point, after a certain time has passed, The electronic closing valve is closed.

  The humidifier of the present invention that operates as described above is capable of injecting water into the water tank by opening the inlet lid on the upper part without separating the water tank from the humidifier body, and injecting the water tank. Water does not overflow through the seating groove or atomization tank of the humidifier body to which the water tank can be separated without closing the palate. This is the sealing between the electronic valve and the water tank and the humidifier body. Achieved by structure.

  That is, a water supply port provided with a needle valve is provided on the bottom surface of the water tank constituting the humidifier of the present invention, and this water supply port is detachably inserted into the seating groove of the humidifier body. A sealing member made of a flexible elastic material such as silicon or rubber is coupled to at least one of the outer peripheral surface of the water supply groove or the inner peripheral surface of the seating groove, thereby being seated on the outer peripheral surface of the water supply port. The outflow of water through the inner peripheral surface of the groove is prevented.

  For example, if the water supply port is inserted into the seating groove while the inner peripheral surface of the pipe-type sealing member is tightly coupled to the outer peripheral surface of the water supply port, the outer peripheral surface of the sealing member is the inner periphery of the seating groove. The sealing member is not separated from the water supply port, and the water supply port must be easily inserted and separated from the seating groove. It is desirable to project and form a large number of flexible ring-shaped sealing projections having elastic force along an arc.

  That is, when the water supply port is inserted, the sealing protrusion of the sealing member is elastically deformed along the vertical direction while being in close contact with the inner peripheral surface of the seating groove. A gap through which water can flow out is not formed between the water supply port and the outer peripheral surface, so that the water tank is connected to the humidifier body and the lid is not connected to the inlet at the top of the water tank. The water supply and the humidifier can be operated even in the state where it is left standing.

  In addition, when the weather is cold, the heater is for heating water supplied to the atomization tank in order to humidify with warm water, and is operated by a heater / vibrator operating sensor. Even when the heater is not required to operate, a separate heater main switch is provided to prevent the sensor from continuing to operate, and only when the main switch is in the ON state, the heater / vibrator operation sensor is provided. It is desirable to allow the heater to operate.

  Details regarding the effects and effects of the present invention including the objects and technical configurations of the present invention should be clarified by the following description with reference to the drawings illustrating preferred embodiments of the present invention.

As illustrated, the upper water supply type humidifier of the present invention, includes an upper inlet I _U of upper lid C1 is detachably coupled, the water supply port D of the spring s operating the needle valve V is mounted on the central portion the lower inlet I _L of the lower lid C2 is detachably coupled is a water trough 21 formed respectively on the top and bottom, of the upwardly open type equipped with a pair of water level sensors S1, S2 and the transducer 22A to the bottom surface An atomizing tank G ′ is formed on one side of the upper surface, and a cylindrical water inlet I _W having a needle valve V opening projection E on an inner diameter portion into which the water supply port D of the water tank 21 is repeatedly inserted is separable. while projecting the central portion of the bottom surface, the electron-off valve V 'duct pipe is bound F' water inlet I _W is connected to the atomization tank G ', repetition is lower lid C2 coupled to water trough 21 Upward open type seating groove that is separably inserted and connected The humidifier body 22 is formed on the other side of the upper surface, and the inner peripheral surface is elastically tightly coupled to the outer peripheral surface of the water supply port D of the water tank 21, and along the arc direction of the outer peripheral surface at regular intervals in the axial direction. projects, and at its outer peripheral edge, water inlet I _W of the inner peripheral tubular multiple ring sealing protrusions E 'is protruded to elastically close contact with the surface sealing member 23.

Reference numeral “24” is a “heater” for heating the water flowing into the atomization tank G ′, and “25” is a “blower” for injecting the atomized water to the outside of the humidifier. "It is.
The pair of water level sensors S1 and S2 reciprocate up and down the floats F1 and F2 along the outer peripheral surfaces of the posts P1 and P2 as the water level changes. One of the two sensors S1 and S2 is a heater / vibrator operating sensor, and the other S2 is an electronic open / close valve operating sensor.

  The heights of the lowest point and the highest point that the floats F1, F2 of the two sensors S1, S2 will reach are the lowest point of the float F2 of the sensor S2 for operating the electronic opening / closing valve → the sensor S1 for heater / vibrator operation. Float F1 lowest point → heater / vibrator actuation sensor S1 float F1 highest point → electronic open / close valve actuation sensor S2 float F2 highest point.

  At this time, the electronic opening / closing valve operating sensor S2 opens the electronic opening / closing valve V ′ from the lowest point of the float F2 to immediately before the highest point and closes it at the highest point, and the heater / vibrator operating sensor S1 The heater / vibrator is stopped at the lowest point of the float F1, and the heater / vibrator is operated from immediately after the lowest point to the highest point.

  The sealing member 23 coupled to the water supply port D and the outer peripheral surface of the water supply port D operates normally without closing the upper lid C1 of the water tank 21 seated in the seating groove G of the humidifier body 22. However, a gap through which water can flow out must not be formed between the outer peripheral surface of the water supply port D and the inner peripheral surface of the seating groove G.

  Further, as shown in FIG. 5, the diameter of the upper and lower steps of the water supply port D is made larger between the upper and lower steps, that is, the diameter of the central portion, and the outer peripheral surface of the central portion having a small diameter has elasticity. When the outer peripheral surface of the central portion of the water supply port D and the inner peripheral surface of the sealing member 23 are brought into close contact with the inner diameter portion of the sealing member 23 and the inner peripheral surface of the sealing member 23 is brought into close contact, the sealing member 23 is more stably connected to the upper and lower step portions J. It is also desirable to be able to maintain it.

  In addition, the cross-sectional shape of the ring-shaped sealing protrusion E ′ formed on the outer peripheral surface of the sealing member 23 in multiple stages in the upward and downward directions is preferably a wedge shape or a triangular shape that decreases in width toward the outside. The maximum outer diameter of the sealing protrusion E ′ of the sealing member 23 in the state of being coupled to the outer peripheral surface of D must be larger than the inner diameter of the seating groove G.

  That is, when the water supply port D to which the sealing member 23 is coupled is inserted into the seating groove G, the outer end portion in the width direction of the sealing protrusion E ′ is elastically deformed upward, and the sealing protrusion E deformed upward is deformed. When 'is in close contact with the inner peripheral surface of the seating groove G by elastic force, no gap is formed between the inner peripheral surface of the seating groove G and the outer peripheral surface of the water supply port D.

The lower lid C2 is coupled to the lower inlet I _L of water bucket 21, can be integrated with water bucket 21, it was configured this way in a separate, by reducing the size of the upper lid C1 better aesthetics, and, in order to facilitate cleaning of the inside of the water bucket 21, in order to form a larger bottom inlet I _L diameter.

However, the lower cover C2 integral with the water bucket 21, and, as it is easy to clean the inside of the water bucket 21 can also be extended form the upper inlet I _U and the lower lid C2.
