A second aspect of the invention proposes a computer-readable storage medium.

A third aspect of the present invention provides a control system of a laundry treating apparatus.

A fourth aspect of the present invention proposes a control system for a laundry treating apparatus.

A fifth aspect of the present invention provides a laundry treating apparatus.

A sixth aspect of the present invention provides a laundry treating apparatus.

In view of this, a first aspect of the present invention proposes a control method of a laundry treatment apparatus comprising: acquiring working parameters of the clothes treatment device in the running process of the dehydration program; determining that the working parameters meet preset conditions; controlling a motor of the laundry treatment apparatus to stop operating, and controlling the laundry treatment apparatus to drain water; controlling the motor to start; and the time length from the moment when the motor stops running to the moment when the motor is started is less than or equal to 120 s.

The control method of the clothes treatment device provided by the invention obtains the working parameters of the clothes treatment device in the running process of the dehydration program, when the working parameters meet the preset conditions, the working parameters show that a large amount of foam exists in the clothes treatment device due to the fact that a user inputs more detergent or the foamability of the detergent is higher, the motor of the clothes treatment device is controlled to stop running, the drainage of the clothes treatment device is controlled to accelerate the drainage of foam water, then the motor is controlled to start, and the step of obtaining the working parameters of the clothes treatment device is further carried out, so that the recycling detection of the foam amount in the clothes treatment device after the drainage operation is carried out is realized. The control method of the clothes treatment device reasonably sets the basis for detecting whether the foam exists and stops running by controlling the motor under the condition that a large amount of foam exists in the clothes treatment device, and drains water, so that the foam is discharged out of the clothes treatment device by means of gravity and the flow of water flow, and the foam is recycled and detected again under the operation of finishing the discharged foam, thus, the power of the motor is ensured to be in a safe use range in the dehydration process, the temperature rise cannot be influenced, and the normal use working condition of the motor is further ensured.

Further, the motor stops running and the drainage is based on the operation which is performed under the condition that the working parameters meet the preset conditions, and the condition that the rotating speed of the motor cannot be increased to the preset rotating speed due to the existence of foam is described, so that the dehydration operation cannot be continuously performed under the current condition, and redundant foam should be timely drained. The problem of in the correlation technique, not taking the foam volume as the benchmark but all adopt the mode of standing for a long time to come from the defoaming and bring the dehydration procedure serious consuming time and can't guarantee the validity that the foam discharged is solved. Meanwhile, the time length from the time when the motor stops running to the time when the motor is started is reasonably set, so that the time length is less than or equal to 120s, namely, the foam is discharged in a standing mode in a short time, namely, the foam water is naturally discharged by utilizing a short time to further achieve the defoaming effect, the influence on the running time length of a dehydration program is reduced, and the next re-dehydration operation is facilitated. If the time between the time when the motor stops running and the time when the motor starts is more than 120s, the running time of the dehydration program is greatly prolonged, and the discharged foam amount is not obviously increased when the time is more than 120s, so that the waste consumption of resources is only caused.

Furthermore, the control method of the clothes treatment device realizes effective detection and effective discharge of the foam amount, further promotes the automation degree of the product while ensuring the dehydration effect, realizes accurate foam detection, further effectively adjusts the dehydration program according to the foam amount, and promotes the service performance and market competitiveness of the product.
