Abstract
A dryer is provided. The dryer may include a second condenser integrally provided with an evaporator and employing a heat pump to maximize a condensation effect so as to enhance heat exchange efficiency, thereby enhancing dehumidifying capability. The dryer may be a circulation type heat pump dryer including a cabinet, a drum, a drying duct to circulate dry air back to the drum, an evaporator having a heat pump, a first condenser, a compressor, an expansion apparatus, and a second condenser to condense refrigerant condensed by the first condenser again so as to supercool the refrigerant during the refrigerant cycle, thereby enhancing dehumidifying capability in the evaporator.
Claims18
A dryer, comprising:
- a cabinet;
- a drum rotatably provided within the cabinet;
- a drying duct provided in the cabinet to circulate air discharged from the drum back into the drum;
- an evaporator and a first condenser sequentially provided on a flow path formed by the drying duct, the evaporator comprising a plurality of heat dissipation fins;
- and
- a compressor and an expansion apparatus configured to form a refrigerant cycle together with the evaporator and the first condenser,
- wherein the evaporator comprises a second condenser configured to receive refrigerant condensed by the first condenser and to condense the received refrigerant again, wherein a refrigerant pipe of the evaporator and a refrigerant pipe of the second condenser are formed in the same heat dissipation fins.
A dryer, comprising:
- a cabinet;
- a drum rotatably provided within the cabinet;
- a drying duct provided in the cabinet and connecting an exhaust port and an inlet port of the drum;
- and
- an evaporator and a first condenser sequentially provided on a flow path formed by the drying duct, wherein the evaporator comprises:
- a first refrigerant pipe arranged on at least one of a plurality of heat dissipation fins of the evaporator and forming a first flow path for refrigerant flowing through the evaporator;
- a second condenser configured to receive refrigerant condensed by the first condenser and to condense the received refrigerant again;
- and
- a second refrigerant pipe arranged on the at least one of the plurality of heat dissipation fins and forming a second flow path for refrigerant flowing through the second condenser,
- wherein the first refrigerant pipe forms a zigzag pattern arranged in a plurality of vertical columns.
