Abstract

The invention discloses a control method of a cooling fan of a heat pump dryer and the heat pump dryer. The heat pump dryer includes a heat pump unit, a drum drive unit, an air supply fan, a control unit and a cooling fan. The heat pump unit includes Compressor, condenser, throttling device and evaporator, the control unit is equipped with a time module and a storage module. Before the heat pump unit works, judge whether to turn on the cooling fan according to the detected ambient temperature; detect the temperature of the condenser coil of the heat pump unit during work, and control the opening and stopping of the cooling fan according to the detected temperature points to adjust the work of the heat pump unit load. The invention can effectively adjust the drying control mode, thereby reducing the energy consumption and drying time of the drying process, and improving 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...
