Abstract

The invention relates to the technical field of clothes treatment, in particular to a drying control method of a drying system. The problems that an existing drying control method is long in drying time and high in energy consumption are solved. To achieve the purpose, the drying control method comprises the steps that in the operation process of a draught fan, the actual humidity Rh of a drying cavity is obtained; based on the humidity interval where the actual humidity Rh belongs, the operation frequency f of a compressor is determined; and the compressor is controlled to operate at the operation frequency f, wherein the actual humidity Rh is in direct proportion to the operation frequency f. According to the drying control method of the drying system, the drying energy consumption can be considered while the drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of clothes treatment, in particular to a drying control method of a drying system. Background technique [0002] In order to realize the rapid drying of clothes, the existing washing machine is equipped with a heat pump drying system. The heat pump drying system mainly includes refrigerant circulation and humid air circulation. Among them, the refrigerant cycle mainly includes a compressor, a condenser, a throttling device and an evaporator, and the wet air cycle includes an air duct and a fan. Set in the air duct. During operation, the humid air in the washing drum enters from one end of the air duct driven by the fan, and returns to the washing drum from the other end of the air duct after flowing through the evaporator and condenser in sequence. When the humid air passes through the evaporator, heat exchange occurs with the evaporator, the moisture in the humid air condenses into water droplets and the...
