Description

Built-in dehumidifier

The present invention relates to a dehumidifier, and more particularly, to a buried dehumidifier installed in a ceiling.

A dress room is a place to store clothes. If there is a lot of pests or moisture in the dress room, the clothes will be damaged. It is therefore important that the dressing room is not exposed to pests or humidity. To control the humidity in the dress room, you can use a dampener or open or close the door frequently. It is also possible to control pests that damage fibers such as insects by using medicines such as naphthalene.

However, the above methods have a problem in that it is necessary to check the replacement time of the dampener or the pesticide every time and replace it on time. If you do not exchange on time, the clothes in the dress room will be damaged. In order to solve the above problems, a dehumidifier can be installed in the dressing room. Dehumidifiers adjust the temperature and humidity to create an environment in which microorganisms such as pests and fungi can not be inhabited. Therefore, clothes stored in the dressing room can be stored hygienically.

However, since the conventional dehumidifier is bulky and heavy, it is difficult to embed and install the dehumidifier.

1 to 5, the buried dehumidifier 100 includes a housing 10, a dehumidifying unit 30, an intake fan 40, and a water receiver 50.

The inner space of the housing 10 is partitioned by the vertically formed partition walls into the intake chamber 11 and the exhaust chamber 12. The lower side of the housing 10 is opened. The housing 10 may have a substantially rectangular parallelepiped shape. A flange portion 10a for fastening a screw or the like may be provided on the lower edge of the housing 10 so that the housing 10 can be embedded and fixed in the ceiling. The housing 10 may be manufactured by injection molding plastic or by pressing a metal. The housing 10 may be partitioned into an intake chamber 11 at the center and an exhaust chamber 12 provided at both sides of the intake chamber 11. [

The dehumidifying unit (30) is installed inside the housing (10) to remove moisture of air. 6, the dehumidifying unit 30 includes a thermoelectric element (not shown), a cooling fin 33 coupled to the heat absorbing portion of the thermoelectric element, a radiating fin 31 coupled to the heat generating portion of the thermoelectric element, And a heat insulating material 32 provided between the fin 33 and the heat dissipating fin 31. The heat insulating material 32 may have a rectangular shape with a central portion corresponding to the size of the thermoelectric element. The thermoelectric element may be a general thermoelectric element that absorbs heat or generates heat by the Peltier effect. The thermoelectric element can direct the heat generating portion to the upper side and the heat absorbing portion to the lower side. The radiating fins 31 are provided across the intake chamber 11 and the exhaust chamber 12 so that the intake chamber 11 and the exhaust chamber 12 communicate with each other.

The intake fan 40 is provided on the upper side of the radiating fin 31 so that the air introduced into the intake chamber 11 enters the upper portion and passes through the radiating fin 31 and then is discharged to the exhaust chamber 12. [ The air passes through the radiating fins 31 and absorbs the heat of the radiating fins 31. The air having absorbed the heat of the radiating fin (31) is discharged to the outside through the exhaust chamber (12).

The water receiver (50) is installed at the lower part of the dehumidifying unit (30) and stores condensed water generated in the heat absorbing unit of the dehumidifying unit (30). The water receptacle 50 may be formed in a rectangular box shape having an open top. The drip tray can be made of plastic or made of metal with an exterior coating so that it does not rust by stored water.

The operation of the embedding type dehumidifier according to the present invention will be described with reference to FIG. 7 shows the flow of air in the dehumidifier shown in Fig.

When the dehumidifier is operated and the intake fan 40 is rotated, the outside air enters the upper portion of the intake fan 40 through the intake chamber 11. The air introduced into the upper portion of the intake fan 40 passes through the heat-radiating fins 31 of the dehumidifying unit disposed at the lower portion of the intake fan 40 to perform heat exchange with the heat-radiating fins 31. Accordingly, the temperature of the heat generating portion of the thermoelectric element coupled to the radiating fin 31 and the radiating fin 31 is lowered, and the air is heated. Since the temperature of the heat generating portion is lowered, the heat absorbing portion that keeps a constant temperature with the heat generating portion by the Peltier effect is also cooled. Therefore, the moisture of the air around the cooling fins (33) coupled to the heat absorbing portion is condensed on the surface of the cooling fins, and the condensed water formed on the cooling fins is collected by the water receiving fins (50).

On the other hand, air heated by heat exchange with the radiating fins 31 is exhausted to the outside of the housing 10 through the exhaust chamber 12. At this time, the air from the radiating fins 31 to the cover frame 20 can be connected to the exhaust duct 70 so that the air flowing into the exhaust chamber 12 through the radiating fins 31 can be well discharged to the outside.

The embedding type dehumidifier configured as described above has the advantage that it is simple in structure and light in weight. Further, since the thickness is small, it can be buried even in a thin ceiling.

The dehumidifier may further include a condensed water discharge unit for discharging the condensed water stored in the water receiver 50 to the outside. The condensate discharge unit may consist of a pump 60 for drawing water from the water receiver 50 and a pipe 61 for guiding the movement of the water. The condensed water discharge unit discharges the condensed water stored in the water receiver 50 to the outside, so that the size of the water receiver can be reduced. When the water receiver is made smaller, the size of the entire product can be reduced. On the other hand, although not shown, the condensate discharge unit may include a check valve to prevent the discharged condensed water from flowing backward. Further, a water level sensor may be disposed inside the water receiver to control the operation of the pump. The water level sensor senses the water level inside the water receiver, and when the water level is above a certain level, a control signal is applied to the pump so that the pump can operate.

The dehumidifying unit (30) can be inclined so that one side faces downward. In this case, since the intake fan 40 is inclined, the outside air can flow into the intake fan 40 more well than when the intake fan 40 is placed horizontally. Therefore, the air and the radiating fins 31 actively exchange heat, and the radiating fins can be cooled well. In this case, the dehumidifying ability of the dehumidifying unit is improved. Also, the condensed water generated in the heat absorbing portion of the dehumidifying unit 30 can be collected in one place.

The water receptacle 50 may be formed in a rectangular box shape having an open top. The gutter can be made of plastic material or made of metal so that it can not be rusted by the stored water.

In addition, the buried dehumidifier may further include a cover frame 20 having a plurality of holes and being detachably coupled to the lower side of the housing 10. By providing the cover frame 20 having a plurality of holes, the foreign matter mixed in the air flowing into the intake chamber 11 can be filtered. The foreign matter mixed in the air discharged to the outside through the exhaust chamber 12 can be filtered.

The holes are formed by a plurality of first wings 20a formed along the major axis direction of the cover frame 20 and a second wing 20b formed along the minor axis direction of the cover frame 20 perpendicular to the first wings 20a, 3 wings 20c. The second wing 20b is formed in the intake chamber 11 and the third wing 20c is formed in the exhaust chamber. The third wing 20c formed at the portion of the exhaust chamber 12 may be inclined so that air is discharged in a direction away from the intake chamber 11. [ In this case, it is possible to prevent the problem that the temperature of the air introduced into the intake chamber comes into contact with the exhausted air and the dehumidifying effect is lowered.

In addition, the flush type dehumidifier may further include a humidity sensor (not shown) that senses humidity and transmits a sensing signal to the controller. The humidity sensor senses the humidity contained in the air introduced into the intake chamber and transmits a detection signal to the control unit. The control unit receives the detection signal from the humidity sensor and stops the device when the humidity falls below a predetermined level, thereby reducing unnecessary energy waste.

An ionizer (not shown) may be installed in the exhaust chamber. The ionizer discharges active hydrogen and anion to remove airborne germs and viruses, so that the inside of the dressing room can be made comfortable. The dresser dehumidifier further including the ionizer can perform air purification functions such as antibacterial, sterilizing, and deodorizing in addition to dehumidification, thereby keeping the dressing room in a comfortable state.

Further, it may further include an LED (not shown) for informing the user of the operation state of the dehumidifier although not shown. In this case, the user can intuitively know when the dehumidifier does not operate due to failure or the like. Therefore, the user can take appropriate measures to prevent damages caused by the dehumidifier not operating.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. There will be. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
