Washing machine and dewatering control method thereof

Abstract

The invention discloses a washing machine which comprises a tank body, a washing and dewatering drum, a pressure detector, a dewatering motor, and a controller, wherein a hanging rod is arranged in the tank body; the washing and dewatering drum is hung in the tank body through the hanging rod; the pressure detector is arranged on the hanging rod and is used for detecting stress of the hanging rod and generating a pressure detection value; the dewatering motor is used for driving the washing and dewatering drum to rotate for dewatering; the controller acquires the pressure detection value fed back by the pressure detector in real time after detecting that a dewatering procedure is started, and controls the dewatering motor according to the pressure detection value. According to the washing device disclosed by the invention, unnecessary energy waste and motor loss can be avoided, and the dewatering performance is guaranteed. The invention further discloses a dewatering control method for the washing machine.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine and a dehydration control method of the washing machine. Background technique [0002] At present, most washing machines control the draining process before dehydration by setting the time. For example, in the dehydration program, a fixed time is set to control the washing machine to drain water, so that dehydration can be performed after the water is drained. However, due to the unreasonable setting of the drainage time, the water in the washing machine has been drained, but the drainage time has not been used up, and it is necessary to wait for the remaining time, thereby increasing the time consumption of dehydration. In addition, after entering high-speed dehydration, it is often set a fixed time for high-speed maintenance. However, when there are fewer clothes, the clothes have already been dehydrated, but the set high-speed dehydration time has n...

Problems solved by technology

However, often due to the unreasonable setting of the drainage time, the water in the washing machine has been drained, but the drainage time has not been used up, and it is necessary to wait for the remaining time, thus increasing the dehydration time.

In addition, after entering high-speed dehydration, it is often set a fixed time for high-speed maintenance. However, when there are fewer clothes, the clothes have already been dehydrated, but the set high-speed dehydration time has not been exhausted, and most manufacturers will dehydrate. The maintenance time is set relatively long, which causes unnecessary energy waste and motor loss, and affects the service life of the washing machine; when there are many clothes, the discount appears that the set dehydration time has ended before the clothes are dehydrated, resulting in dehydration. Non-drying phenomenon, causing user dissatisfaction
