Embodiment Construction

[0023] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0024] see Figure 1 to Figure 5 , the embodiment of the present invention provides a control method for detecting the drainage of the washing machine. The timing starts from the drainage, and the initial water level is recorded, and the water level is detected once every preset time interval, and the current water level is compared ...

Abstract

The invention discloses a control method for detecting drainage of a washing machine and the washing machine, and belongs to the technical field of washing. The control method includes the steps of starting timekeeping from the moment of drainage and recording the initial water level; performing water level detection once every preset time; comparing the current water level with the previous waterlevel; if the water level change value is smaller than a constant K, giving an alarm. The washing machine is controlled by the control method. By performing detection once every preset time, the detection frequency is increased, breakdown can be found in time, and long-time waiting is avoided; if the comparison between the current water level and the previous water level indicates that the waterlevel changes, it is shown that drainage is being preformed; the set constant K is used for detecting whether the drainage amount is normal or not so as to prevent blockage of a drainage pipe.

Description

technical field [0001] The invention relates to the technical field of washing, in particular to a control method for detecting the drainage of a washing machine and the washing machine. Background technique [0002] At present, the drainage control method of the fully automatic washing machine mostly adopts the method of directly pulling the drainage valve to drain to the set water level by the drainage pump or by the traction motor. The current program control method is to set a certain drainage time, such as 8 minutes. After the washing machine enters the drainage program, after the timer reaches 8 minutes, the water level sensor starts to detect and judge whether the water level is below the reset water point. If it reaches or is lower than the reset water level, it can enter the dehydration program. If it does not reach the reset water level, it will start draining. Call the police. [0003] The drainage control method of the above-mentioned fully automatic washing ma...
