Embodiment 1

[0034] like figure 2 , image 3 As shown, the sealing ring 3 of the present invention is a flat annular structure, and an annular sealing rib 4 is provided on the upper surface and / or the lower surface of the sealing ring 3 . Due to the large radius of the sealing ring installed at this position, the ordinary sealing ring is easily displaced or rolled up and deformed by force during installation, and the sealing effect cannot be achieved. The above-mentioned flat ring structure of the present invention increases the stability of the sealing ring during installation , to avoid deformation and displacement, and at the same time use the annular sealing rib on the surface to effectively achieve the sealing effect.

Embodiment 2

[0036] like Figure 5 , Image 6 As shown, the upper surface and / or the lower surface of the sealing ring 3 are respectively provided with two annular sealing ribs 4 .

Embodiment 3

[0038] like image 3 As shown, the sealing ring 3 and the flange 2 in this embodiment are provided with a matching positioning structure.

[0039] The positioning structure includes a positioning protrusion 5 provided on the sealing ring 3 and a positioning groove (not shown) provided on the flange 2 to match the positioning protrusion.

[0040] More preferably, the positioning protrusion 5 integrally protrudes from the outer periphery of the sealing ring 3 , and the notch integrally formed on the outer periphery of the limiting sinker 8 constitutes the positioning groove.

[0041] The positioning structure can ensure that the sealing ring 3 does not shift radially and along the circumference when the sealing ring 3 is squeezed by the inner tub bottom 1 and the flange 2 and is subjected to a torque force when the washing machine is working. Ensure the sealing effect of the sealing ring 3.

Abstract

The invention relates to a flange sealing and installing structure of a washing machine inner cylinder bottom. The flange sealing and installing structure comprises the inner cylinder bottom, a flange and a seal ring, wherein an annular limiting sedimentation groove is formed in a binding face of the flange and the inner cylinder bottom; and the seal ring is clamped in the limiting sedimentation groove in a positioning manner. The seal ring in the flange sealing and installing structure of the washing machine inner cylinder bottom is of a flat annular structure; and at least one lap of annular seal convex ribs is arranged on the upper surface and / or the lower surface of the seal ring. According to the invention, the flange sealing and installing structure does not have radial-directional and movement deformation under the stress condition, so that the advantage that the sealing effect of the inner cylinder bottom and the flange is ensured during the working process of the washing machine is realized. The flange sealing and installing structure has the characteristics of high convenience and rapidity in installation, simple structure and good sealing effect.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a sealing structure for a washing machine inner tub bottom, in particular to a flange sealing installation structure for a washing machine inner tub bottom. Background technique [0002] In the existing pulsator type washing machine, when doing laundry, the space between the inner tub and the side wall of the outer tub needs to be filled with water, so the structure of the inner tub does not need to be sealed, especially the bottom of the inner tub. There are also gaps, and even on the basis of ensuring the strength of the bottom of the inner bucket, water outlet holes will be added. [0003] In the pulsator washing machine with this structure, this part of water between the inner and outer tubs does not participate in washing, and the water that actually participates in washing is only the part in the inner tub, which causes a large waste of water resources. In addition, too much...
