At the same time, the volume of the fixed cavity 3 can be changed, thereby changing the volume of the detergent which is put in each time.
According to the washing machine, water is fed into the constant volume valve cavity by using the negative pressure channel of the throat part of the venturi tube in the water inlet water channel, the constant volume valve cavity is cleaned by using the constant volume valve, the constant volume valve is emptied by using a siphon effect, the water flow of the water inlet generates negative pressure by using the venturi effect, the detergent in the detergent box of the washing machine is pumped into the constant volume valve cavity, and then the detergent in the constant volume valve cavity is flushed into the washing bucket by using the negative pressure channel of the throat part of the venturi tube in the water inlet water channel. When the detergent is put in, residual liquid in the cavity of the constant volume valve is discharged first, so that the accuracy of the amount of automatically added detergent is ensured. The cleaning pipeline is omitted, and the washing agent is flushed into the washing bucket by using water inlet of the negative pressure channel of the venturi tube, so that the water inlet time is saved, and the washing period is shortened.
