Abstract

The invention discloses a heat pump clothes dryer, and relates to the technical field of clothes dryers. The heat pump clothes dryer comprises a drying cylinder, a fan and an air channel. A heat pump system is arranged in the air channel and comprises an evaporator, a throttling valve, a condenser and a compressor which are sequentially connected end to end, the evaporator is connected with the condenser, and the condenser is connected with an air inlet of the drying cylinder; a cooling chamber is connected between an air outlet of the drying cylinder and the evaporator, and a cooling device is arranged in the cooling chamber and used for pre-cooling hot and humid air discharged out of the drying cylinder. According to the heat pump clothes dryer, on one hand, moisture condensation is accelerated through the cooling chamber, the dehumidifying efficiency of the evaporator is improved, the clothes drying time is shortened, the system operation power consumption is reduced, and energy is saved; on the other hand, after hot and humid air is pre-cooled through the cooling chamber, the temperature of the condenser can not rise too fast, and thus the system temperature is balanced.

Description

technical field [0001] The invention relates to the technical field of clothes dryers, in particular to a heat pump clothes dryer. Background technique [0002] With the changes in Chinese people's lifestyles and the enhancement of health awareness, the public's demand for clothes dryers is gradually emerging. The heat pump dryer works on the principle of heat pump and drying, and is divided into two types: open cycle and closed cycle. Among them, the closed cycle is composed of heat pump cycle and air cycle. The heat pump circulation system is mainly composed of compressor, cooler, throttle valve, evaporator and so on. Air circulation is composed of drying cylinder, air duct, circulation fan, etc. After the clothes dryer is turned on, the humid air in the air duct is driven by the circulation fan, passes through the cooler and absorbs the heat released by the cooler, and its temperature rises. The relative humidity decreases, and then enters the drying cylinder to releas...
