The present application is related to and claims the benefit of the Korean Patent Application No. 10-2015-0022536, filed on Feb. 13, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
Embodiments of the present disclosure relate to a dehumidifier configured to be used as to lower the humidity of an indoor space.
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 is provided to pass through the condenser configured to condense refrigerant. The air that is dehumidified is heated by absorbing heat from the refrigerant of the condenser while passing through the condenser, and thus the air of the indoor space is provided with reduced humidity and higher temperature at the same time while passing through the evaporator and the condenser at an inside of a housing.
To address the above-discussed deficiencies, it is a primary object to provide, for use in a dehumidifier having a structure configured to adjust the temperature of the air being outlet from an outlet hole of the dehumidifier.

Referring to
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
As illustrated on
The dehumidifier 100 according to the present disclosure is provided such that the air that is inlet through the second inlet hole 114 is outlet through the second outlet hole 113 after passing through the second condenser 141, and the air that is inlet through the first inlet hole 112 is outlet through the first outlet hole 115 after passing through the first condenser 140, and thus energy is dispersed to two units of outlet holes Q1 and Q2. Therefore, as the temperature of the air being outlet from the first outlet hole 113 toward a user is lowered, the user may be provided with further comfortable atmosphere.
Furthermore, the dehumidifier 100 according to the present disclosure is configured to provide a driving condition of three modes including a warm air dehumidification mode, general dehumidification mode, and a cool air dehumidification mode so that a user may adjust the temperature of the air being outlet through the first outlet hole 113 as desired.

During the general dehumidification mode, heat exchange at high temperature may be performed first at the second condenser 141 by opening the second compressor-exit-valve 172 and by closing the first compressor-exit-valve 171, as the heat exchange at high temperature is performed at the condenser at which refrigerant is directly received from the compressor. Through the above, as heat exchange at low temperature is performed at the first condenser 140 disposed at a moving path 180 of the air moved by use of the first draft fan 150, the air having moderately warm temperature is outlet from the first outlet hole 113.

Referring to
During the warm air dehumidification mode, heat exchange is performed only by use of the first condenser 140 by opening the first compressor-exit-valve 171 and by closing the second compressor-exit-valve 172, and air at high temperature is outlet through the first outlet hole 113.
