Clothes dryer

A clothes dryer, comprising a housing, a tumbler and a heat exchange component, wherein

• the housing has an air cavity therein, the air cavity located below the tumbler,
• the air cavity and the tumbler form a closed-loop air duct,
• a blower impeller for driving air in the closed-loop air duct to flow is provided in the housing, the blower impeller is adjacent to a first end of the air cavity,
• the heat exchange component comprises a compressor, and a condenser and an evaporator, wherein
• the condenser and the evaporator are placed inside the air cavity,
• the compressor is used to compress a working medium into a high temperature and high pressure state,
• the condenser communicates with the evaporator through a throttle capillary,
• the heat exchange component further comprises a reversing valve, wherein
• the reversing valve is configured to switch between a first mode and a second mode,
• in the first mode, the working medium flows from the compressor to the condenser via the reversing valve, the working medium in the condenser flows into the evaporator, and the working medium in the evaporator flows back to the compressor via the reversing valve, and
• in the second mode, the working medium flows from the compressor to the evaporator via the reversing valve, the working medium in the evaporator flows into the condenser, and the working medium in the condenser flows back to the compressor via the reversing valve,
• a blower cover installed at a back of the housing, the blower cover covers the first end of the air cavity near to the blower impeller and a first end of the tumbler, and a second end of the tumbler communicates with a second end of the air cavity, and
• a mesh filter located in the air cavity and disposed in the air cavity between the condenser and the blower impeller, the mesh filter disposed directly adjacent to the condenser and the blower impeller.
