Embodiment Construction

[0019] exist figure 1 In , indicated as a whole by numeral 1 is a sealing assembly for a drum of a washing machine (laundry washer).

[0020] Washing machines are known per se and are therefore not described or illustrated for the sake of brevity.

[0021] Essentially, the washing machine comprises a washing chamber 2, a drum 3 housed in the washing chamber 2 (known and figure 1 Only schematically shown in ) and a motor (not shown), the motor drives the drum shaft 4 integrally connected to the drum 3 via a specific transmission system (not shown), so that the drum 3 rotates.

[0022] Shaft 4 extends along axis A and turns about axis A (axis of rotation) and is arranged through hole 5 of wall 6 of the washing machine which separates washing chamber 2 from an auxiliary compartment 7 housing the motor.

[0023] A sealing assembly 1 separates the washing chamber 2 from a compartment 7 housing the motor in a liquid-tight manner.

[0024] In addition to the shaft 4, the sealing a...

Abstract

The invention relates to a sealing component (1) for a drum (3) of a washing machine and the washing machine with the same. The sealing component comprises a drum shaft (4), a supporting member (10) for supporting the drum, and a sealing element (11), wherein the drum shaft (4) extends along an axis (A), rotates around the axis and passes through a hole (5) on a wall (6) of the washing machine; the supporting member (10) is fixed to the drum and is integrally connected to the drum shaft so as to rotate the drum; and the sealing element (11) seals the hole (5) in a liquid-tight mode and is provided with a pair of radial sealing lips (21 and 22) and at least one axial sealing lip (24); the pair of radial sealing lips (21 and 22) are arranged side by side along the axis (A) and are in sliding fit with a cylindrical sealing surface (23) which is arranged around the drum shaft (4); the axial sealing lip (24) is matched with a front sealing surface (25); and the front sealing surface (25) is carried by the supporting member (10) and is basically vertical to the axis (A).

Description

technical field [0001] The present invention relates to a sealing assembly for a drum of a washing machine, and to a washing machine having a drum provided with said sealing assembly. Background technique [0002] A washing machine (clothes washer) with a drum usually includes a washing chamber, a drum accommodated in the chamber, and a motor that drives a shaft through a specific transmission system so as to rotate a cross member integrally connected to the drum; In a compartment separate from the washing chamber, the shaft is provided through a hole in said wall; a sealing element must therefore be mounted to seal this hole and separate the washing chamber from the compartment housing the motor in a liquid-tight manner. [0003] According to a general solution, the sealing element is provided with a pair of radial sealing lips slidingly cooperating with the side surfaces of the shaft (or of a bush embedded on the shaft). This sealing element can have various forms and con...
