Description

Sealing structure for drum door body of washing machine and washing machine

technical field

The present invention relates to washing machine equipment in household appliances, in particular to a top-loading drum washing machine, in particular to a drum washing machine whose drum is composed of a non-porous inner cylinder without dehydration holes and whose top is provided with a clothes feeding port .

Background technique

Washing machines can generally be classified into pulsator type, agitator type and drum type washing machines. Generally speaking, washing machines remove stains from laundry through the action of water and detergent.

The pulsator washing machine performs washing operations by rotating a pulsator in the center of the washing tub left and right. The agitator washing machine uses the friction between the water flow and the laundry to perform the washing operation by rotating the rotating blade in the center of the washing tank left and right. The drum type washing machine beats the clothes by rotating the drum to perform the washing operation.

A drum-type washing machine generally has a casing, an outer cylinder for containing washing water is installed inside, a drum for containing laundry is arranged inside the outer cylinder, and a motor and shaft for rotating the above-mentioned drum are arranged on the back of the outer cylinder.

In addition, there is also a control unit for controlling the laundry process, generally a control panel, water inlet and drainage mechanisms, and the like. The drum type washing machine removes stains contained in the laundry using the frictional force between the washing water stored in the water tank and the laundry in the drum, and the chemical action of the detergent contained in the washing water.

As an important part of the washing machine, the washing drum is not only used to accommodate the washing, constitute the washing container, but also participate in the washing work, especially the drum washing machine, which mainly relies on the rotation of the washing drum to lift and throw the clothes to form a beating effect At the same time, the washing drum also has a certain rubbing effect on the clothes, thus relying on beating and washing to create the washing effect; and in addition to the pulsator washing, many existing pulsator washing machines also use the washing drum to wash at the same time, such as the popular on the market. The so-called "dual power" washing machine.

Compared with the pulsator washing machine, the weakness of the drum washing machine is that since the door is set on the front side, it is inconvenient to open the door to add clothes again after entering the water, and to put or take out the clothes, one has to bend down or squat down to get the clothes. It is very inconvenient for the elderly or pregnant women. Thus there has been a top-loading drum washing machine, which has the advantages that the drum washing machine is clean and wears little, and the upper opening of the pulsator washing machine takes and places clothes and can add clothes midway.

In view of this, the present invention is proposed.

The ribs 10 are arranged alternately with the limiting ribs 9 .

In this embodiment, the two ends of each rotating rib 10 are respectively in limited contact with the corresponding ends of the adjacent limit ribs 9 on both sides, so as to further improve the stability of the door body 300 during rotation, and effectively prevent the door body 300 from producing a shaft. to the displacement.

In this embodiment, the rotating shaft 14 sequentially passes through the perforation provided at the end of the rotating shaft groove 15, the perforation provided on the rotating rib 10 on the corresponding side of the door body 300, and the perforating provided on the limiting rib 9 in the rotating shaft groove 15; preferred , Each perforation set on the rotating shaft groove 15, the rotating rib 10 and the limiting rib 9 is coaxially arranged. Also, in this embodiment, the two ends of the rotating shaft 14 are fixedly connected to the corresponding side walls of the rotating shaft groove 15, so that the rotating shaft 14 is fixedly installed in the rotating shaft groove 15, so that the door body 300 can rotate around the rotating shaft 14, and the rotating shaft 14 It does not penetrate into the inside of the drum 200, which not only ensures the tightness of the drum at the joint of the rotating shaft 14, but also realizes the purpose of the door body 300 rotating around the shaft.

In this embodiment, the rotating shaft groove 15 is sunken toward the inside of the drum 200, and the perforations on both sides of the rotating shaft groove 15 communicate with the inside of the drum 200, and a dynamic seal is provided at the perforation, so that the end of the rotating shaft 14 is connected to the end of the rotating shaft groove 15 through a dynamic seal. Set perforation phase fixed installation. The above descriptions are only preferred embodiments of the present invention, and do not limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology of this patent Without departing from the scope of the technical solution of the present invention, personnel can use the technical content of the above prompts to make some changes or modify them into equivalent embodiments with equivalent changes. Technical Essence Any simple modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the solutions of the present invention.
