Description

TECHNICAL FIELD

[0001] One or more example embodiments relate to a dehumidifier.

BACKGROUND ART

[0002] In general, a dehumidifier is an apparatus for removing moisture contained in air, and has been provided with various types of dehumidifying systems.

[0003] In most cases, there has been widely used a cooling dehumidifier that removes humidity by condensing moisture contained in air while the air passing through an evaporator based on a refrigeration cycle.

[0004] Such dehumidifier may include a case that forms an appearance, a fan installed in the case to suction external air, a dehumidifying mean that removes moisture by condensing humidity contained in the suctioned air, and a water tank in which water generated in the dehumidifying mean is stored.

[0005] The dehumidifying mean may include a compressor that compresses a gaseous refrigerant at a high temperature and a high pressure, a condenser that condenses the refrigerant gas discharged from the compressor with the high temperature and the high pressure, and an evaporator that evaporates a low-pressure refrigerant having passed through the evaporator and a capillary (inflation tube).

[0006] In such dehumidifier, a refrigerant is circulated by the compressor from the evaporator, through the condenser and the capillary, to the evaporator again.

[0007] In this instance, when air is suctioned into a case due to rotation of the fan, the suctioned air may be cooled by the refrigerant to be below the dew point while passing the evaporator and condensed such that moisture contained in the air is formed to be waterdrop, and then removed.

[0008] As the use of the dehumidifier becomes common, research on the dehumidifier has been actively carried out. For example, Korea Patent Application No. 2011-0098956 filed on Sep. 29, 2011 discloses a dehumidifier for home using.

[0036] Referring to FIGS. 1 and 2, a dehumidifier 10 may include a body 100 that suctions air through an inlet 110 and discharges the air through an outlet 120, a heat exchanger 200 that includes an evaporator 210 and a condenser 220 and removes moisture in the air suctioned through the inlet 110, a blower 300 that guides the air dehumidified in the heat exchanger 200 to the outlet 120, and a cooler 400 disposed between the inlet 110 and the heat exchanger 200. The cooler 400 may absorb heat from the suctioned air to reduce a temperature of the suctioned air.

[0037] The dehumidifier 10 may further include an accommodator 500 disposed below the heat exchanger 200 to collect a portion of dehumidification water falls from the heat exchanger 200, a compressor 600 disposed below the accommodator 500 to compress a gaseous refrigerant at a high temperature and a high pressure, and a water tank 700 detachably attached to the body 100 and located in a front part of the body 100. Dehumidification water generated in the evaporator 210 may be collected in the water tank 700.

[0038] Referring to FIG. 3, the cooler 400 may include a cooling element 410 that absorbs heat of air F suctioned through the inlet while the suctioned air is passing through the cooling element 410, and a heat dissipation element 420 disposed below the cooling element 410 to receive the heat absorbed by the cooling element 400 and dissipate the heat.

[0039] In addition, the cooler 400 may further include a Peltier element 430 disposed between the cooling element 410 and the heat dissipation element 420 to connect the cooling element 410 and the heat dissipation element 420 such that heat moves therebetween.

[0040] A lower end of the cooler 400 may be immersed in the dehumidification water collected in the accommodator 500. For example, a portion of the heat dissipation element 420 may be immersed in the dehumidification water collected in the accommodator 500.

[0041] The Peltier element 430 may be a thermoelement. When two different metals are in contact with each other with a contact point, a metal surface of one side may absorb heat and a metal surface of another side may release the heat in response to a direct current (DC) voltage being applied to both ends of the two metals.

[0042] In this example, the cooling element 410 connected to the metal surface absorbing the heat of the Peltier element 430 may absorb the hear from the air passing through the cooling element 410 to reduce the temperature of the air. Also, the heat dissipation element 420 connected to the metal surface releasing the heat of the Peltier element 430 may release the heat absorbed from the cooling element 410 to the dehumidification water collected in the accommodator 500.

[0043] An operation state of the dehumidifier 10 having the above structure will be explained in the following description.

[0044] In the dehumidifier 10, the inlet 110 may be formed in a rear surface of the body 100. However, a location of the inlet 110 is not limited thereto, and the inlet 110 may also be formed in a front surface of the body 100. Also, a replaceable filter may be attached to the inlet 110 to prevent foreign objects such as dust from entering the body 100.

[0045] The air F suctioned into the body 100 through the inlet 110 may be thermally dissipated by the cooling element 410 of the cooler 400 while passing through the cooler 400 disposed between the inlet 110 and the heat exchanger 200. Through this, the temperature of the air F suctioned into the body 100 may be reduced.

[0046] In this example, the heat absorbed by the cooling element 410 may be transmitted to the heat dissipation element 420 by the Peltier element 430. The heat dissipation element 420 may release the heat to the dehumidification water collected in the accommodator 500. A portion of the heat dissipation element 420 may be immersed in the cold dehumidification water of the accommodator 500 so as to allow more efficient heat dissipation.

[0047] As such, the dehumidifier 10 may reduce the temperature of the air F suctioned from an outside by arranging the cooler 400 to be between the inlet 110 and the heat exchanger 200. The temperature-reduced air may be cooled in the evaporator 210 so that condensate water is formed. Through this, the air may be dehumidified. While the dehumidified air is passing through the condenser 220, the temperature of the dehumidified air may increase. Thereafter, the dehumidified air may be guided by the blower 300 to the outlet 120, and then discharged to the outside. In this example, a portion of the dehumidification water condensed in the evaporator 210 may be collected in the accommodator 500 and a remaining portion of the dehumidification water may be collected in the water tank 700.

[0048] As described above, the dehumidifier 10 including the cooler 400 disposed between the inlet 110 and the heat exchanger 200 may reduce the temperature of the air F suctioned from the outside. Accordingly, a cooling efficiency in the evaporator 210 may be improved, and an overall dehumidification efficiency of the dehumidifier 10 may be improved.

[0049] Hereinafter, another example of the dehumidifier 10 will be described. For brevity, repeated description will be omitted.

[0050] Referring to FIG. 4, a dehumidifier 10 may include a body 100 that suctions air through an inlet 110 and discharges the air through an outlet 120, a heat exchanger 200 that includes an evaporator 210 and a condenser 220 and removes moisture in the air suctioned through the inlet the inlet 110, a blower 300 that guides the air dehumidified in the heat exchanger 200 to the outlet 120, and a cooler 400 disposed between the heat exchanger 200 and the blower 300. The cooler 400 may absorb heat from suctioned or discharged air to reduce a temperature thereof. The dehumidifier 10 may further include the accommodator 500, the compressor 600, and the water tank 700 described herein.

[0051] Referring to FIG. 5, a humidity of the air may be reduced while the air is passing through the evaporator 210. Also, the temperature of the air may be increased while the air is passing through the condenser 220. Thereafter, the cooler 400 may reduce the temperature of the air.

[0052] In other words, high-temperature air dehumidified by the heat exchanger 200 may be thermally dissipated by the cooling element 410 of the cooler 400 while passing through the cooler 400 disposed between the heat exchanger 200 and the blower 300. Through this, a temperature of air F' discharged from the body 100 through the outlet 120 may be reduced.

[0053] In this example, the heat absorbed by the cooling element 410 may be transmitted to the heat dissipation element 420 by the Peltier element 430. The heat dissipation element 420 may release the heat to the dehumidification water collected in the accommodator 500.

[0054] As described above, the dehumidifier 10 including the cooler 400 disposed between the heat exchanger 200 and the blower 300 may reduce the temperature of the air F' discharged to the outside, thereby providing an environment in which a user feels comfortable.
