Abstract

The invention discloses a clothes treatment apparatus, including a drum rotatably provided within a cabinet to accommodate washing and drying objects; and a heat pump module including an evaporator, acompressor, a condenser, and an expansion valve, through which a refrigerant is circulated, to provide heat to air discharged from the drum and circulated to the drum, wherein the heat pump module further includes an internal heat exchanger configured to exchange heat between the refrigerant discharged from the condenser and the refrigerant passing through the evaporator.

Description

technical field [0001] The present disclosure relates to a laundry treating device having a heat pump system. Background technique [0002] The laundry treating apparatus generally refers to a washing machine that performs a function of washing laundry, a clothes dryer that performs a function of drying laundry that has been washed, or a washing machine and a dryer that perform both washing and drying functions. [0003] A laundry treating apparatus including a drying function is provided with a hot air supply unit for supplying hot air to items to be dried put into the laundry receiving portion. According to the type of heat source for air, hot air supply units can be classified into gas heaters, electric heaters, and heat pump systems. [0004] A heat pump system includes a compressor, condenser, expansion valve, and evaporator. The high-temperature and high-pressure refrigerant compressed in the compressor circulates through the condenser, expansion valve, evaporator, a...
