Problems solved by technology

[0002] In related technologies, various methods can be used to dry objects; in the scheme of using a heat pump system to dry objects, the auxiliary heating of auxiliary heating equipment can be used to speed up the drying speed of objects; The cooling fan cools down the compressor of the heat pump system to prevent the compressor from overheating; in related technologies, the auxiliary heating equipment and the cooling fan are controlled in linkage, for example, when the outlet temperature of the compressor reaches a set threshold, the cooling fan is controlled Start to work and control the auxiliary heating equipment to stop working at the same time; even if the cooling fan is turned on, the outlet temperature of the compressor will need to go through a period of temperature rise before cooling down. After it is turned on, the outlet temperature of the compressor will also increase, which is prone to overheating of the compressor, which reduces the operation safety of the heat pump system; in addition, when the cooling fan is turned on, the auxiliary heating equipment is turned off, which will also reduce the drying efficiency.

Abstract

The embodiment of the invention discloses a drying device, a clothes dryer, a washing-drying all-in-one machine and a drying method. The drying device comprises a first heating device, a heat pump system, an accommodating apparatus, a fan, a first heating device, a controller and a cooling device, wherein the heat pump system comprises a compressor and a condenser; the controller is used for obtaining a drying instruction, and controlling the fan, the first heating device and the heat pump system to start working, controlling the first heating device to stop work while a compressor outlet temperature is determined to be greater than or equal to a first temperature threshold value or a condenser outlet temperature is determined to be greater than or equal to a second temperature threshold value, and controlling the cooling device to start working while the compressor outlet temperature is determined to be greater than or equal to a fifth temperature threshold value, wherein the fifth temperature threshold value is smaller than the first temperature threshold value or the second temperature threshold value. In this way, the drying device prevents compressor from overheating, improvessafety of the drying device, prevents auxiliary heating device from shutting down in advance, and improves drying efficiency.
