Pump, washing machine and control method of washing machine

Abstract

The pump comprises a pump cavity, a water inlet, a drainage outlet and a circulating water outlet are formed in the pump cavity, a valve block rotating along the inner wall of the pump cavity is arranged in the pump cavity, and the valve block is connected with a driving device for controlling the valve block to rotate to different positions so as to correspondingly open and close the drainage outlet or the circulating water outlet. The invention further discloses a washing machine provided with the pump, the washing machine comprises an outer barrel containing washing water, a drainage pipeline and a circulation pipeline, one end of the drainage pipeline is communicated with the outer barrel, and the other end of the drainage pipeline is communicated with a drainage port; one end of the circulating pipeline is communicated with the outer barrel, and the other end is communicated with the circulating water outlet. The pump has the functions of water drainage and water circulation, the size of the pump body is reduced, the space of a washing machine body is saved, other parts can be conveniently assembled, the assembling efficiency is improved, and the production cost is reduced. The invention further discloses a control method applied to the washing machine. The invention further discloses a control method applied to the washing machine.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a pump, a washing machine and a control method for the washing machine. Background technique [0002] Along with the raising of living standard, washing machine has become one of indispensable household appliances in people's life. According to their different washing principles, washing machines are generally divided into pulsator washing machines and washing machines. The pulsator washing machine washes clothes by operating the water flow generated by the pulsator in the washing tub, while the drum type washing machine washes clothes by vertically falling clothes caused by the rotation of the drum. For washing clothes. [0003] At present, most pulsator or drum washing machines have the function of circulating water. The treated wastewater is transported to the body of the washing machine for secondary use through the circulating water pump. The circul...

AI Technical Summary

Problems solved by technology

[0003] At present, most pulsator or drum washing machines have the function of circulating water. The treated wastewater is transported to the body of the washing machine for secondary use through the circulating water pump. The circulating water pump and the drain pump are usually set at the bottom of the outer tub of the washing machine, and There are also components such as a reducer and a drainage motor installed at the bottom, and the installation of a circulating water pump results in a tight space at the bottom of the outer tub, which affects the installation of other parts of the washing machine and reduces the assembly efficiency of the washing machine, which is not conducive to the industrial production of the washing machine

[0004] For example, the Chinese patent discloses a washing machine, which includes a body, an inner cylinder, a filter assembly, a circulation pump assembly, and a drain pump. The filter assembly has a water inlet, a water outlet, and a drain that communicate with the filter chamber, and the circulation pump assembly is connected to the filter assembly. And it is connected to the water outlet, and the drainage pump is connected to the filter assembly and connected to the drainage outlet. However, the circulation pump assembly and the drainage pump are both installed at the bottom of the outer tub, so that the space at the bottom of the outer tub is seriously insufficient, which affects the installation of other parts of the washing machine.
