Problems solved by technology

[0002] The tripod is installed between the inner cylinder and the outer cylinder of the inner cylinder washing machine, and is one of the important parts of the inner cylinder washing machine. In the prior art, the tripod of the inner cylinder washing machine generally adopts aluminum castings. When washing, the inner cylinder is completely immersed in water. Make the tripod contact with sewage and dirt for a long time, and even dirt will accumulate on the tripod. Sewage and dirt will corrode the tripod. It is difficult to replace the position of the tripod. Once it is corroded and damaged, the staff needs to disassemble the body. heavy workload
[0003] In addition, the lint, fluff and other dirt produced during the washing process adhere to the tripod and the flange of the inner cylinder, which will breed a lot of bacteria, endanger the health of users, and affect the user experience
[0004] The Chinese patent No. 201521131602.7 discloses that a sealing strip is installed between the flange and the tripod to solve the problem of accumulated dirt between the flange and the tripod, but the washing water will also corrode the tripod, which cannot completely solve the corrosion of the tripod question
[0005] The Chinese patent No. 201610838923.3 discloses that a plastic sealing cover is installed on the outside of the tripod. During the washing process, the plastic sealing cover will also absorb dirt and produce bacteria, which cannot fundamentally solve the dirt on the tripod and the rear flange of the inner cylinder.

Embodiment 1

[0055] Such as Figure 1 to Figure 6 As shown, two sealing structures are provided in the area between the inner cylinder 1 and the outer cylinder 2 in this embodiment, including the first sealing structure 3 and the second sealing structure 4, which divide the area between the inner cylinder 1 and the outer cylinder 2 into The first sealing part 30 , the communicating part 10 and the second sealing part 40 are arranged in sequence along the axial direction of the inner cylinder 1 and are isolated from each other.

[0056] In this embodiment, a dehydration hole 9 is provided on the side wall of the inner cylinder 1, and the dehydration hole 9 communicates the interior of the inner cylinder 1 with the communicating portion 10, and the first sealing structure 3 is arranged on the side wall close to the closed end of the inner cylinder 1, and the The first sealing portion 30 is separated from the dehydration hole 9; the second sealing structure 4 is arranged on the side wall near...

Embodiment 2

[0065] Such as Figure 3 to Figure 5As shown, the sealing structure described in this embodiment includes a ring-shaped first sealing ring disposed on the outer wall of the inner cylinder 1 and a second sealing ring disposed on the inner wall of the outer cylinder 2 respectively. The first sealing ring and the second sealing ring The rings are in the same section, and the outer peripheral surface of the first sealing ring is in limited contact with the inner peripheral surface of the second sealing ring, so that the contact between the first sealing ring and the second sealing ring is sealed during the rotation of the inner cylinder 1 .

[0066] In this embodiment, the outer peripheral surface of the first sealing ring is provided with at least one ring of grooves 6 extending in the circumferential direction of the sealing ring and recessed inward along the radial direction of the sealing ring, and the inner peripheral surface of the second sealing ring is provided with Each g...

Abstract

The invention discloses a drum washing machine, which comprises an inner drum and an outer drum, wherein the outer drum sleeves the inner drum; a sealing structure is arranged between the inner drum and the outer drum; the sealing structure divides an area between the inner drum and the outer drum into a sealing part and a communicating part; the sealing part is a closed area; and the communicating part communicates with the inside of the inner drum through a dewatering hole arranged in the wall of the inner drum. A tripod, a flange plate, a motor shaft and the like are arranged at the rear end of the inner barrel. The sealing structure is additionally arranged between the inner barrel and the outer barrel, the direct contact between the washing water and the flange plate, the tripod and the motor shaft at the rear end of the inner barrel is isolated, the dirty and corrosion problems are thoroughly solved, the washing water cannot enter a sealing part, and the unnecessary water consumption is reduced.
