Water supply system and water supply method for washing machine, washing machine

Abstract

The invention provides a water supply system for a washing machine, a water supply method and a washing machine. The water supply system includes a water supply pipeline and a pressure water storage tank arranged on the water supply pipeline, a frequency conversion pump, a valve assembly and a control system, wherein: the water supply pipeline is connected to the washing bucket and is used to supply water to the washing bucket; the frequency conversion pump , which is arranged on the water outlet pipe of the water supply pipeline, and is used to provide the water supply lift; the pressure water storage tank is arranged between the frequency conversion pump and the washing tub; the valve assembly includes a first solenoid valve and a second solenoid valve, wherein The first solenoid valve is arranged on the water inlet pipe of the water supply pipeline on the inlet side of the frequency conversion pump, and the second solenoid valve is between the pressure water storage tank and the washing tub; Pressure, the water pressure of the water supply pipeline and the actual water level of the washing bucket control the disconnection of the valve assembly and the speed of the variable frequency pump. The invention replenishes water quickly, and ensures that the washing machine can not stop running water when there is a temporary water shortage or insufficient water supply pressure.

Description

technical field [0001] The invention relates to a washing machine, in particular to a water supply system and a water supply method for the washing machine, and the washing machine. Background technique [0002] With the continuous development of the urban population, the population density continues to increase. People often face the embarrassing situation of low water pressure and insufficient water during peak water consumption. In places where water resources are scarce, water is supplied in a time-period manner, and people often face the embarrassment of having no water when they need water. [0003] At present, when washing machines on the market are faced with temporary water shortage or insufficient water pressure, people are at a loss what to do, resulting in the problem of prolonged laundry time. Because the existing washing machine faces the defects of long water intake time and replenishment time during the laundry process. Therefore, it is necessary to provid...
