Problems solved by technology

[0003] Among them, the electric heating type is widely used in the market because of its simple structure, high drying efficiency, and easy maintenance; while the drying system dries the clothes for a long time, it will inevitably absorb the lint of the clothes, causing the drying effect to change. Poor, in severe cases, it may even lead to unit failure
[0004] The cleaning of the drying system of the electric heating type washer-dryer on the market mainly depends on the manual cleaning of the after-sales personnel, which is not only complicated, but also laborious
At present, the self-cleaning of the drying system in the market is completely blank

Embodiment 1

[0036] like figure 1 As shown, the self-cleaning control method of this embodiment is applied to the integrated washer-dryer, mainly to add self-cleaning control to the drying system of the integrated washer-dryer. The self-cleaning control method includes the following steps.

[0037] Step S11: Detect the actual rotational speed S of the drying fan at the end of each drying procedure. In this embodiment, after each unit of the integrated washer-dryer is dried by the drying fan of the drying system, the actual rotation speed S of the drying fan is detected.

[0038] Step S12: judging whether the actual rotational speed S of the drying fan is less than or equal to the set threshold. In this embodiment, the set threshold value is 95% of the rated speed S1. Wherein, among S / S1≤95%, the value of 95% can be adjusted according to needs, and the adjusted range belongs to the application scope of the invention.

Embodiment 2

[0049] see figure 2 , the self-cleaning control method of the drying system in the washer-dryer in this embodiment is similar to the corresponding method in Embodiment 1, and the method in this embodiment includes the following steps.

[0050] Step S21: Detect the actual rotational speed S of the drying fan at the end of each drying procedure. In this embodiment, after each unit of the integrated washer-dryer is dried by the drying fan of the drying system, the actual rotation speed S of the drying fan is detected.

[0051] Step S22: judging whether the actual rotational speed S of the drying fan is less than or equal to the set threshold. In this embodiment, the set threshold value is 95% of the rated speed S1. Wherein, among S / S1≤95%, the value of 95% can be adjusted according to needs, and the adjusted range belongs to the application scope of the invention.

[0052] When the actual rotation speed of the drying fan is less than or equal to 95% of the rated rotation spee...

Abstract

The invention discloses a self-cleaning control method and device for a drying system of a washing and drying integrated machine and the washing and drying integrated machine. The self-cleaning control method includes the following steps that the actual rotating speed of a drying fan is detected at the end of each drying process; whether or not the actual rotating speed of the drying fan is smaller than or equal to a set threshold value is judged; when the actual rotating speed of the drying fan is smaller than or equal to the set threshold value, the drying system enters a self-cleaning mode.By means of the self-cleaning mode of the drying system, the service life of the drying system can be prolonged, the failure rate of a unit can be reduced, the drying experience of a user can be improved, and the drying efficiency can be improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a self-cleaning control method for a drying system in an integrated washing and drying machine, a control device and the integrated washing and drying machine. Background technique [0002] The all-in-one washer-dryer has developed rapidly in recent years. Because it integrates a washing machine and a clothes dryer, it has attracted the attention of consumers in the market. At present, the drying system of the washing and drying machine in the market is mainly divided into two types, one is the heat pump type, and the other is the electric heating type. [0003] Among them, the electric heating type is widely used in the market because of its simple structure, high drying efficiency, and easy maintenance; while the drying system dries the clothes for a long time, and inevitably absorbs the lint of the clothes, resulting in a change in the drying effect. In severe cases, it may even lead to u...
