Impeller, impeller assembly and washing machine

Abstract

The invention relates to the technical field of washing machines, and discloses an impeller, an impeller assembly and a washing machine. A protruding part is formed on one side of the impeller, a cavity is formed in the other side of the impeller, and a mounting part is arranged in the cavity; in the height direction of the impeller, a distance between the bottom end surface of the mounting part and the plane where the opening at the lower end of the cavity is located is kept, a water through hole is not formed in the side cavity wall of the cavity, and a sealing structure used for providing aseal for the top end of the cavity is arranged at the top end of the protruding part, so that a sealed pressure air cavity is formed by means of the seal provided by the sealing structure and a waterseal spilling over the opening at the lower end of the cavity after the impeller is mounted; water cannot go into the mounting part and soak the mounting part, so that the situation that the mountingpart is in contact with water and clothing debris is effectively avoided, and the problems are avoided that dirt forms below the impeller and the surface of a metal insert in the mounting part is corroded.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a pulsator, a pulsator assembly and a washing machine. Background technique [0002] At present, with the improvement of people's quality of life, the penetration rate of washing machines is getting higher and higher. For example, the pulsator washing machine on the market. [0003] The central area of ​​the pulsator of the pulsator washing machine protrudes toward the laundry washing side to form a raised part, thereby forming a cavity on the opposite side of the pulsator, and a mounting part connected to the power drive shaft is arranged in the cavity. At the same time, the screw passes through the raised part and is connected to the power drive shaft assembled with the mounting part. [0004] However, after the pulsator washing machine with such a structure is used for a long time, because the pulsator is soaked in water for a long time, clothing debris will remain ...

AI Technical Summary

Problems solved by technology

[0004] However, after the pulsator washing machine with such a structure is used for a long time, because the pulsator is soaked in water for a long time, clothing debris will remain on the pulsator, especially in the central area of ​​the pulsator, forming dirt, breeding mold, and polluting the clothes.

In addition, the pulsator insert connected to the power drive shaft in the installation part is generally made of aluminum alloy. When washing clothes, they will be soaked in the water under the pulsator for a long time, and the surface will also have corrosion problems.

In addition, if the screws connecting the pulsator and the power drive shaft are soaked in water for a long time, dirt will form on the surface, and even rust will occur, resulting in reduced reliability and difficult maintenance.
