Description

TECHNICAL FIELD

Embodiments of the present disclosure relate to a dehumidifier configured to be used as to lower the humidity of an indoor space.

BACKGROUND

In general, a dehumidifier is an apparatus configured to remove moisture in air. The dehumidifier may be largely distinguished into a drying-type dehumidifier and a cooling-type dehumidifier. The drying-type dehumidifier is a type of the dehumidifier configured to perform a dehumidification by absorbing or adsorbing the moisture in the air by using dehumidifying agent, while the cooling-type dehumidifier is configured to condense the moisture in the air by cooling the temperature of the air below dew point by use of a cooling cycle apparatus.
The cooling-type dehumidifier, at an inside of a case forming an exterior appearance, includes components of the cooling cycle, such as a compressor, a condenser, an expansion apparatus, and an evaporator, and a draft fan configured to have air at an indoor space move through the case by generating inlet force and draft force. By having the air of the indoor space pass through the evaporator at an inside of the case, the moisture included in the air is condensed on a surface of the evaporator, and thus the dehumidification is performed.
In the dehumidifier in general, the air that is dehumidified after passing through the evaporator i s provided to pass through the condenser configured to condense refrigerant. The air that is de humidified is heated by absorbing heat from the refrigerant of the condenser while passing throu gh the condenser, and thus the air of the indoor space is provided with reduced humidity and hi gher temperature at the same time while passing through the evaporator and the condenser at a n inside of a housing.

Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged humidifier. Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
Referring to FIG. 1, a conventional dehumidifier 10 includes a case 11 having an inlet hole 12 and an outlet hole 13, a compressor 90 to compress refrigerant, a condenser 40 to condense the refrigerant and radiate latent heat to an outside, a cooling cycle apparatus having an expansion apparatus 91 to expand the refrigerant and an evaporator 20 to absorb the latent heat of the outside by evaporating the refrigerant and condense the moisture in the surrounding air, and a draft fan 50 to inlet air through an inlet hole 12 and move the inlet air to be outlet through the outlet hole 13 after dehumidified through the evaporator 20 and then heated while passing through the condenser 40.
The dehumidifier is provided such that the air 80 entered through the one inlet hole 12 is outlet to the one outlet hole 13 after passing through the evaporator 20 and the condenser 40, and thus heat Q transferred from the condenser is concentrated at the one outlet hole 13. Therefore, a user may feel inconvenience by the air 80 being outlet at higher temperature than the surrounding temperature.
Referring to FIG. 2, a dehumidifier 100 includes an outer case 111 having a first inlet hole 112, a first outlet hole 113, a second inlet hole 114 (FIG. 9), and a second outlet hole 115. In addition, the dehumidifier 100 includes a compressor 190 to compress refrigerant, a first condenser 140 and a second condenser 141 to condense refrigerant and radiate latent heat to an outside, and a cooling cycle apparatus having an expansion apparatus 191 to expand refrigerant and an evaporator 120 to absorb latent heat of an outside by evaporating refrigerant and condense moisture of the surrounding air. In addition, the dehumidifier 100 includes a first draft fan 150 to inlet air through the first inlet hole 112 and move the inlet air to be outlet through the first outlet hole 113 after the inlet air is dehumidified through the evaporator 120 and then heated while passing through the first condenser 140, and a second draft fan 151 to inlet air through a second inlet hole 114 and move the inlet air to be outlet through the second outlet hole 115 after the inlet air is heated while passing through the second condenser 141.
As illustrated on FIG. 9, the second inlet hole 114 may be provided at a side surface of the dehumidifier 100, or may be provided at a random direction other than the direction that is identical to the second outlet hole 115.
