Helical corrugation flexible rubber water sealing envelope

Abstract

This invention provides a spiral ripple soft rubber water sealing cover corresponding to the washing machine' s case and barrel incorporating together which has special requirement for the water sealing, it includes outer circle part, spiral ripple part, insider circle part which configures as the bowl. Its characteristic is that the spiral ripple part is a protruding water ripple worm which circumrotates from inside to outside. When it is applied, it can try its best to prevent the transform of the inertial body' s vibration to the barrel and base because the spiral ripple soft rubber water sealing can flex along three dimension directions and is suitable to the characteristic of the inertial body twisting movement, when the automatic wave wheel washing machine drains the water, the water in the ripple channel can automatically flow out along the spiral ripple and not stay. So the stable case barrel and the moving driving cover axes of the washing machine can connect by the spiral ripple soft rubber water sealing cover, it can satisfy the up and down of the inertial body, reduce the vibration and attach the aim of connecting the case barrel and driving caver axes.

Description

technical field [0001] The invention relates to a sealing member, in particular to a spiral corrugated flexible rubber water sealing sleeve used in a full-automatic pulsator washing machine integrating a shell and a barrel to connect a shell and barrel with a drive sleeve shaft. Background technique [0002] Existing full-automatic pulsator washing machine consists of a water storage bucket, dehydration bucket, pulsator, electric drive and clutch device to form a motion inertial system. This inertial body is the main vibration source in the washing machine's work; The bucket in the middle is connected with the drive sleeve shaft through a hard rubber water seal sleeve. [0003] The fully automatic pulsator washing machine with shell and barrel has eliminated the shell of the existing full-automatic pulsator washing machine, and combines the traditional shell and the bucket into one, that is, the shell is also the bucket, and the bucket is also the shell (referred to as: She...

AI Technical Summary

Problems solved by technology

The dehydration bucket, pulsator, electric drive and clutch device of the shell-tub-in-one automatic pulsator washing machine form a motion inertia system. Similarly, this inertial body is the main vibration source in the work of the shell-tub in-one automatic pulsator washing machine; This inertial body has the following motion characteristics in the shell-tub-in-one automatic pulsator washing machine: the inertial body will rise and fall due to different weights in different working stages, such as adding dry clothes, it will increase, and it will become lighter after water injection ( buoyancy effect), the heaviest before dehydration after draining (wet clothes), and gradually become lighter after dehydration (gradually dry); the vibration generated by the inertial body is the strongest during the dehydration working stage, and the vibration is caused by the biased clothes with the high speed of the dehydration bucket It is caused by rotational motion, which is a composite motion of rotation (dehydration barrel), horizontal swing (revolution) and vertical vibration; therefore, the sealing water connection method between the stationary shell barrel and the drive sleeve shaft that moves with the above-mentioned inertial body cannot be used. The traditional hard rubber sealing water jacket is connected, otherwise, the severe vibration will be transmitted to the shell and bucket through the hard rubber sealing water jacket, so that the shell and bucket in one automatic wave wheel washing machine cannot work normally, and may even be damaged by the vibration
