Washing machine as well as water drainage device and water drainage control method thereof

Abstract

The invention discloses a washing machine as well as a water drainage device and water drainage control method thereof. The control device comprises a water drainage assembly, a water level detection end and a detection unit, wherein the water drainage assembly is used for draining water in the washing machine; the water level detection end is arranged in the water drainage assembly to detect the water level of the water drainage assembly; the input end of the detection unit is connected with the water level detection end and the output end of the detection unit is connected with a main control unit of the washing machine; the detection unit is used for generating a detection signal according to the water level of the water drainage assembly and outputting the detection signal to the main control unit so that the main control unit controls the water drainage assembly according to the detection signal. The water drainage assembly is controlled to drain water or stop draining water according to the water level of the water drainage assembly, thus being capable of reducing the working hours of the water drainage assembly under the condition that the water drainage requirement is met, reducing the noises generated when the washing machine carries out dehydration, promoting the user experience, reducing the energy consumption of the washing machine and prolonging the service life of the water drainage device.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a washing machine drainage device, a washing machine with the device and a washing machine drainage control method. Background technique [0002] The washing machine in the related art will generate a lot of noise during dehydration, especially in the final stage of dehydration, because the residual water in the pump chamber of the drain pump is small, the centrifugal force generated by the impeller cannot discharge the residual water to the outside of the washing machine, and the water will The circulating back flow back to the pump body, so repeated circulation, resulting in loud noise of the drainage pump. However, there is no effective method in the related art to reduce the noise generated during drainage, which easily causes user complaints, and the drainage pump continues to work, resulting in high energy consumption of the washing machine and reducing the se...
