Problems solved by technology

The above two options for strengthening the end wall have rather narrow limits as stronger plastic would basically make the barrel more expensive and strengthen the end wall as well as build up of material due to stress relief structures
In modern machines with a centrifuge rotation speed of more than 1500 rpm and a load of more than 8 kg, in particular the rotating drum, it is not possible to use the existing structure of the bucket with a reinforced structure made only of plastic

Embodiment Construction

[0043] figure 1 The rear part of the plastic tub 1 is shown from the front in a perspective view. This component comprises the end wall 3 and is produced in one piece by injection moulding. In subsequent operation, this member 1 is firmly connected to the cylinder of the tub 1 , also made of plastic.

[0044] The hollow cylindrical cavity-free bearing mounting 2 is formed centrally in the end wall 3 . This bearing mount is intended to receive a fluid-tight bearing, not shown, for the drive shaft of a laundry drum, also not shown, which is arranged in the tub 1 . The more detailed embodiment of the hollow cylindrical bearing mount 2 is dictated by the corresponding exact design of the bearing to be used, which is not important here. In any case, the bearing mount 2 consists of dense plastic without cavities, since the bearing mount must withstand the forces of the rotating washing drum, which may be adversely affected by unbalanced loads, and must accordingly Designed to be...

Abstract

The invention relates to a plastic suds tub (1) for a washing machine, particularly for a washing machine having a front side opening for loading and unloading the device with items to be washed, said plastic suds tub (1) comprising a cylindrical jacket (7) and an end side wall (3) closing the jacket (7) and having a hollow, cylindrical, void-free bearing mount (2) for a bearing of a shaft of a washing drum that can rotate in the suds tub (1), and having stabilizing means (5), characterized in that the end side wall (3) has an additional stabilizing component (5) mounted on the outside thereof as a stabilizing means (5). The suds tub (1) is characterized by exceptional strength, which is sufficient to withstand the high mechanical loads transferred to the suds tub during operation of washing machines having large drum volume and high loads.

Description

technical field [0001] The invention relates to a plastic tub for a washing machine, in particular a washing machine with a front opening for loading and unloading laundry, said plastic tub having a cylindrical housing and an end wall closing the housing, said end wall There is a hollow cylindrical solid bearing mount for the bearing of the shaft of the washing drum that can rotate in the tub and structure for reinforcement. Background technique [0002] The invention is based on a washing machine having a housing and a washing assembly suspended within the housing on springs, wherein the washing mechanism comprises a cylindrical plastic tub, a washing machine supported for rotation within the tub, A drum and a driving motor, the axis of the washing drum is arranged substantially horizontally, and the driving motor drives the laundry drum directly or from the outside via an intermediate pulley. The end wall of the tub has bearing mounts for supporting the drum shaft. [00...
