Patent ID: 8312640

Claim:
A cloth dryer comprising: (a) a tub for accommodating clothes; (b) a heat exchange air-flow path for circulating air in the tub; (c) a heat pump disclosed in the heat exchange air-flow path, the heat pump including: a compressor for compressing a refrigerant; a heat radiator for exchanging heat between air in the heat exchange air-flow path and the refrigerant which has been compressed by the compressor and turned into a high temperature and high pressure state so that the refrigerant can radiate heat; a throttling section for decompressing the refrigerant which has radiated the heat in the heat radiator and turned into a high pressure state; a heat absorber for exchanging heat between the air in the heat exchange air-flow path and the refrigerant which has been decompressed in the throttling section and turned into a low temperature and low pressure state so that the refrigerant can deprive the ambient air of heat; and a pipe line for connecting the compressor, the heat radiator, the throttling section, and the heat absorber and (d) a blower for supplying the air heated in the heat radiator into the tub, wherein the heat radiator and the heat absorber include a stack of common fins for integrating the heat radiator and the heat absorber into one body, and the integrated heat radiator and absorber is disposed in the heat exchange air-flow path, wherein the heat absorber and the heat radiator are each formed with a refrigerant pipe , and the pipe forms meanders and extends through the fins generally in a stacking direction of the fins, wherein a heat-transfer reducing section is formed in the respective fins between a portion of the fins defining the heat absorber and a portion of the fins defining the heat radiator such that the heat-transfer reducing sections extend along the same direction as the pipe extends, and wherein the stack of common fins is slanted around an axis extensive in the stacking direction so that a lowest part of the heat absorber is positioned lower than a lowest part of the heat radiator.
