Abstract

The invention discloses a control method of a heat pump dryer cooling fan and a heat pump dryer. The heat pump dryer comprises a heat pump unit, a drum driving unit, an air supply fan, a control unit and a cooling fan, wherein the heat pump unit comprises a compressor, a condenser, a throttling device and an evaporator, and the control unit is provided with a time module and a storage module. Before the heat pump unit is operated, whether the cooling fan is turned on or not is judged according to the temperature of testing environment. The temperature of a condenser coil of the heat pump unit is detected during operation, and the cooling fan is controlled to be turned on or off according to detected different temperature points so as to regulate the workload of the heat pump unit. The control method has the advantage that the drying control mode can be effectively regulated, thereby reducing energy consumption and drying time in the process of drying and increasing the drying efficiency.

Description

technical field [0001] The invention relates to a clothes drying device and a clothes drying method, in particular to a method for controlling a cooling fan of a heat pump clothes dryer capable of adjusting the work load of a heat pump and the heat pump clothes dryer. Background technique [0002] The following air circulation channel is arranged in the existing heat pump type clothes drying device: the heated air heated by the condenser in the heat pump cycle system is sent into the drying room containing the clothes, and the moist air which has taken moisture from the clothes is It is sent back to the evaporator for cooling and dehumidification, and the dehumidified air is heated by the condenser again and sent to the drying room. [0003] Chinese Patent Application No. 200610153406.9 discloses a clothes drying device capable of stabilizing the operation of a heat pump generating drying air circulating between the drying chamber and the heat pump. Among them, the air heat...
