Description

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

Technical Field

The invention relates to washing machine equipment in household appliances, in particular to a top-opening type drum washing machine, in particular to a drum washing machine, wherein a drum consists of a pore-free inner drum without a dewatering hole, and a clothes feeding port is arranged at the top of the drum.

Background

Washing machines can be largely classified into pulsator type, agitator type, and drum type washing machines. Generally, a washing machine removes stains from laundry by the action of water and detergent.

The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub in a left-right direction. The pulsator type washing machine performs a washing operation by using a frictional force between a water current and laundry by rotating a rotation fin at the center of a washing tub in a left-right direction. The drum type washing machine performs a washing operation by rotating a drum to beat laundry.

In general, a drum type washing machine has a housing in which an outer tub for accommodating washing water is installed, a drum for accommodating laundry is provided inside the outer tub, and a motor and a shaft for rotating the drum are provided at the rear surface of the outer tub.

In addition, there are control parts for controlling the progress of the laundry, typically a control panel, and water inlet and drainage mechanisms, etc. The drum type washing machine removes stains contained in laundry by using friction between wash water stored in a tub and the laundry in a drum and chemical action of detergent contained in the wash water.

The washing drum is used as an important part of the washing machine, is not only used for containing washings to form a washing container, but also can participate in washing work, in particular to the drum washing machine, mainly lifts and throws clothes by virtue of the rotation action of the washing drum so as to form a beating effect, and meanwhile, the washing drum has a certain rubbing effect on the clothes, so that the washing effect is achieved by virtue of beating and washing; in addition to pulsator washing, many existing pulsator washing machines also use a washing drum for washing, such as so-called "double-power" washing machines, which are popular in the market.

Compared with the pulsator washing machine, the drum washing machine has the weakness that the machine door is arranged at the front side, so that after water enters, the machine door is inconvenient to open, clothes are added again, the clothes are contained or taken out, and the clothes are taken out by bending down or squatting down, so that the drum washing machine is inconvenient for old people or pregnant women. The top-opening type drum washing machine has the advantages of being small in washing and abrasion of the drum washing machine, and capable of taking and putting clothes through an upper opening of the pulsator washing machine and adding the clothes in the middle.

The present invention has been made in view of this.

In this embodiment, the rotating shaft 14 sequentially passes through the through hole provided at the end of the rotating shaft groove 15, the through hole provided on the rotating rib 10 at the corresponding side of the door 300, and the through hole provided on the limiting rib 9 provided in the rotating shaft groove 15; preferably, the rotating shaft groove 15, the rotating rib 10 and each perforation arranged on the limiting rib 9 are coaxially arranged. In this embodiment, the two ends of the rotating shaft 14 are fixedly connected with 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, the door 300 can rotate around the rotating shaft 14, and the rotating shaft 14 does not penetrate into the drum 200, thereby not only ensuring the tightness of the drum at the joint of the rotating shaft 14, but also achieving the purpose of rotating the door 300 around the shaft.

In this embodiment, the shaft groove 15 is recessed toward the inside of the drum 200, and the perforations provided on both sides of the shaft groove 15 are communicated with the inside of the drum 200, and the perforation is provided with a dynamic seal, so that the end of the shaft 14 is fixedly mounted with the perforation provided on the shaft groove 15 through the dynamic seal. The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present invention without departing from the scope of the invention.
