A washer-dryer with heat pump drying and dehumidification functions

Abstract

The invention discloses a washing and drying machine with heat pump drying and dehumidification functions, which comprises an outer cylinder, an inner cylinder coaxially arranged inside the outer cylinder, a heat pump system, and a drying circulation air path between the outer cylinder and the heat pump system. The drying circulation air path successively passes through the heat pump air outlet, the outer cylinder air inlet, the inside of the outer cylinder, the outer cylinder air outlet, the heat pump air inlet, the heat pump system and then to the heat pump air outlet. The humid air inlet and dry air outlet of the humid air flow from the outside to the outside through the humid air inlet, heat pump inlet, heat pump system, heat pump outlet, dry air outlet and then to the outside to form a dehumidification circulation air path. There is a switching mechanism between the drying and dehumidification circulation air passage to realize the switching between clothes drying and dehumidification functions. The drying circulation air passage and the dehumidification circulation air passage are equipped with the same double-layer lint filter. The washing and drying machine of the invention has multiple functions, and can not only dry clothes, but also dehumidify and dry rooms.

Description

technical field [0001] The invention relates to a washer-dryer, in particular to a washer-dryer which is dried by a heat pump, especially a washer-dryer capable of dehumidifying the surrounding environment. Background technique [0002] Generally, the washing machine is used in the bathroom, and the surrounding space has a lot of moisture and high humidity. In addition, in the room during the rainy season, the indoor quilts and clothes will also become moldy, smelly, or even rotten due to the high humidity of the air. With the improvement of living standards, people are increasingly pursuing a comfortable living environment. Air humidity directly affects people's daily life. Excessive humidity can make people feel damp and stuffy, and prolonged exposure to humid environments can also damage people The health of the body causes many diseases and causes things to rust, mold and deteriorate. [0003] At present, the electrical equipment related to drying clothes and dehumidifi...

AI Technical Summary

Problems solved by technology

[0005] The heat pump drying method has the following disadvantages: Insufficient lint filtration will lead to clogging of the aluminum sheet of the evaporator in the heat pump module, resulting in a reduction in drying efficiency; the functions are relatively single, only used as drying clothes, while the existing refrigerated dehumidifier It is not suitable for use in residential houses or hotels, but only in some special occasions, such as laboratories, precision equipment rooms, etc.
