Embodiment Construction

[0035] Such as figure 1 As shown, the air sealing device of the washing machine of the present invention, its basic principle is to utilize Boyer's theorem that "the pressure of the gas will increase with the shrinkage of the volume", and in combination with the principle of liquid circulation "the liquid is in a stationary object, The trend of its filling is an upward trend to maintain a horizontal state".

[0036] The sealing device is arranged between the bottom of the inner tub 1 and the bottom of the outer tub 2 of the pulsator washing machine, the motor shaft sleeve 3 extends between the bottom of the inner tub 1 of the pulsator washing machine and the bottom of the outer tub 2, and surrounds the motor shaft 4 and the motor shaft sleeve at the bottom of the inner tub 1 3. There is a chamber 5 with a circumferential closed bottom opening facing the bottom of the outer tub. The opening of the chamber 5 is facing the bottom of the outer tub 2. The upper end of the motor sha...

Abstract

The invention discloses an air sealing method and an air sealing device for a washing machine. A sealing structure is designed by using the gap between an air sealing motor shaft and a motor shaft sleeve, adopting the principle that pressure intensity and volume are in an inverse ratio in the Boyle law and consulting the principle that air is sealed on a horizontal plane; annular convex ribs of certain height are arranged at the bottom of an inner drum of the washing machine to form a semi-closed chamber; when the water is continuously fed, a compressed air cavity can be formed in the chamber; and when the sealing port at the end of the motor shaft sleeve is positioned in the air cavity sealed by the water, the air in the air cavity can play a good role in sealing the water. By using the simple structure, seal between the motor shaft and the motor shaft sleeve of the washing machine is realized; the device has low production cost and good sealing effect; and improvement on seal between the motor shaft and the motor shaft sleeve of the washing machine can be realized without increasing high improvement cost on the conventional washing machine production line.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine shaft sealing device, in particular to an air sealing method and device for a pulsator washing machine. Background technique [0002] In existing washing machines, the seal between the assembly hole in the middle of the inner and outer barrels and the motor shaft is generally realized by structures such as rubber sealing rings. This structure adds another structure between the inner and outer barrels and the motor shaft. On the one hand, the rubber material The structure of the machine is easy to age, and on the other hand, it puts forward higher requirements for the machining accuracy of the hole and the shaft, which increases the cost of the machine. Many manufacturers have improved the shaft seal of the washing machine. [0003] The Chinese patent application number 200810186973.3 discloses a rotating shaft sealing device of a washing machine and a washing machine using ...
