The present invention relates to a technical field of household appliances, and more particularly to a heat pump module for a laundry treatment device and the laundry treatment device.
A washer-dryer is an intelligent novel washing machine, provided with an additional drying function based on an automatic washing machine, and thus combining many functions, such as washing, spinning and drying, into a single machine in one. The washer-dryer may have two types, namely, an air-vented washer-dryer and a condensation-based washer-dryer. The air-vented washer-dryer works in such a principle that air is heated by a heater to heat clothes and then becomes wet hot air to be exhausted, thereby carrying away moisture in the clothes in such a circulation and achieving a purpose of drying the clothes. The condensation-based washer-dryer works in such a principle that air enters a drum to heat clothes after heated by a heater, the drum is filled with wet hot air which is condensed into water by a condensation system and then collected in a water storage box, and hence moisture in the clothes is taken away in such a circulation, so as to achieve a purpose of drying the clothes.
A heat pump washer-dryer belongs to the condensation-based washer-dryer, in which installation space for a cooling fan of a compressor is very limited due to a space problem.
The present invention aims to solve at least one of the problems existing in the related art. Thus, embodiments of the present invention provide a heat pump module for a laundry treatment device that has advantages of simple structure and excellent performance.
