Washing and drying integrated machine and its drying control method and device

Abstract

The invention discloses a washer-dryer and its drying control method and device. The method includes the following steps: when the washer-dryer executes a drying program, the temperature of an outlet is detected, and the heating tube is controlled according to the temperature of the outlet Open or close; get the adjacent drying time decrease value, and judge the drying period of the washer-dryer according to the adjacent drying time decrease value; if it is in the early stage of drying, control the motor to drive during the closing period of the heating tube The drum performs rotary drum heat rejection work, and / or controls the drainage pump to run at the first preset rotation-stop ratio; if it is in the later stage of drying, control the motor to drive the drum to perform low-speed shake-off work during the closing of the heating pipe, and / or The drain pump is controlled to run at the second preset rotation-stop ratio. This method divides the drying process into different periods, and controls the motor to run at different speeds and drain pumps with different rotation and stop ratios according to the drying period, thereby improving the drying efficiency and drying of the washer-dryer. Dry effect.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, and in particular to a drying control method of an integrated washer-dryer, a drying control device of an integrated washer-dryer, and an integrated washer-dryer. Background technique [0002] At present, when the all-in-one washer-dryer executes the drying program, the motor of the all-in-one washer-dryer is generally controlled to run at a constant low speed during the drying period, and the drain pump is controlled to run at a constant turn-to-stop ratio. [0003] Because the water output rate is higher in the early stage of drying than in the later stage of drying, controlling the drainage pump to operate at a constant turn-off ratio cannot meet the drainage requirements of the washer-dryer, which affects the drying effect. And the whole process controls the motor to run at low speed, which affects the separation effect of moisture and load, thus affecting the drying efficiency....

AI Technical Summary

Problems solved by technology

[0003] Due to the higher water output rate in the early stage of drying than in the late stage of drying, controlling the drainage pump to operate at a constant turn-off ratio cannot meet the drainage requirements of the washer-dryer, which affects the drying effect

And the whole process controls the motor to run at low speed, which affects the separation effect of moisture and load, thus affecting the drying efficiency
