Description

Ring seal for a washing machine and machine dryer and a washing machine and / or dryer machine with a gasket annul such.

The invention relates to an annular gasket for a washing machine and / or dryer machine, as well as a machine washer and / or dryer machine with such an annular seal.

Washing machines present in the common of the cases a frame, which forms an outer part or a housing of the washing machine. The frame has an anterior opening or Top to load and unload clothes. The opening is closable through a door. Inside the frame is arranged a lye receptacle or also called a wash tank, which contains water and cleaning agent during the operation, for washing clothes. Inside of lye receptacle, a drum is installed. The drum is loaded with clothes, for washing clothes. For the regime of washing the drum is filled with water and the cleaning agent and rotates around an axis of rotation. The drum is operated for rotation, by means of an engine or something similar. To avoid water and clothing manage to penetrate a space between the receptacle of bleach and the frame, an annular gasket is arranged between the Lye receptacle and frame. This ring joint also serves to dampen vibrations, which are generated by means of drum rotation, particularly during high speeds.

WO 2007/063072 A1 discloses an annular joint for a washing machine. The ring seal has a flange anterior and a posterior flange. Between the anterior flange and the posterior flange there are two areas in the essential U-shaped, which join the two flanges with each other. Anterior flange It is intended for mounting to the frame of the washing machine. He rear flange is intended for mounting to the receptacle bleach of the washing machine. The anterior flange and the flange later they are configured continuously in direction perimeter. The ring seal has an area on the flange posterior, which extends inward in radial direction. During a washing machine operation the drum rotates above this area, in sliding contact.

To ensure that the ring seal does not move or it may not rotate during machine operation washing machine, it must be mounted fixed to the bleach receptacle. For hold the ring gasket to the bleach receptacle safely, the bleach receptacle may have a previous area nerve, essentially in the form of J. For the assembly of the joint annular, it must be stretched above the nerve of the lye receptacle.

In other known solutions, the ring seal, which is normally produced from rubber or some other material appropriate rubbery elastic, has a nerve, which serves to the clamping of the ring seal to the bleach receptacle. This type of annular joints is easier to assemble, but does not present the resistance force against rotation, such as ring joints described above.

At the moment there is for that reason the problem, that with the increase in resistance force, which provides for annular joints against rotation, it becomes the Ring joint mounting much more difficult. This refers first of all to those ring joints, which are configured relatively rigid at least in that area, which is stretched above the nerve of the lye receptacle.

It is a task of the invention, to cite a meeting cancel for a washing machine and / or dryer machine, which is Easy to assemble, it has a sufficient resistance force against a rotation during operation of the washing machine and / or dryer machine and has excellent sealing properties; a washing machine and / or dryer machine must also be created with such an annular seal.
