Description

Notched seal structure of outer bucket of washing machine

Technical Field

The utility model relates to a seal structure, especially an outer notched seal structure of bucket of washing machine.

Background

In the prior art, in the washing stage of the drum washing machine, the larger the height difference formed by the inner drum is, the more powerful the clothes are beaten, and the better the washing effect is; in the dehydration stage, the larger the diameter of the inner drum is, the larger the centrifugal force generated by the clothes is, the better the dehydration effect is, and the lower the moisture content of the clothes is. However, when the drum type washing machine is operated, since the inner tub rotates at a high speed to generate a local excessive centrifugal force to the laundry to cause vibration, a random deviation phenomenon of the center of mass is inevitably caused, and the vibration caused by the inner tub is transmitted to the outside of the drum type washing machine through the outer tub and the cabinet; in order to prevent the vibration from being transmitted from the inner barrel to the machine shell through the outer barrel, the existing roller washing machine needs to be provided with a gap between the inner barrel and the outer barrel and a gap between the outer barrel and the machine shell for arranging a vibration-proof device for buffering and damping the vibration of the outer barrel so as to ensure that the washing machine has sufficient space to generate shaking displacement during high-speed rotation; therefore, under the condition of standard casing width (600 mm), the diameter of the inner cylinder of the mainstream drum washing machine (for example, the capacity is 10 kg) on the market at present is about 500mm mostly, and the diameter cannot be larger.

In order to enlarge the diameter of the inner cylinder, the outer cylinder is relatively fixed to reduce the gap between the outer cylinder and the machine shell, although the diameter of the inner cylinder can be enlarged to a certain degree, because the displacement of the vibration of the inner cylinder cannot be avoided, a gap of about 25mm is still left between the inner cylinder and the outer cylinder, the diameter of the inner cylinder can only be about 520mm, and compared with the diameter of the inner cylinder of the existing mainstream product drum washing machine, the improvement is not obvious.

Therefore, the applicant can enlarge the size of the outer barrel in the width direction of the shell to be equal to the width of the shell by cutting the outer barrel into the notch, and effectively enlarge the size of the inner barrel in the width direction of the shell by enlarging the outer barrel, so that the diameter of the inner barrel can be increased to the maximum extent under the condition that the size of the shell of the washing machine is not changed; however, how to seal the cut to ensure the convenience of assembly and disassembly, and reduce the vibration transmitted to the casing by the movement of the outer barrel along with the inner barrel is a problem to be solved in the present washing machines.
