Drum of a machine for the careful treatment for clothes

Abstract

A drum of a machine for the treatment of clothes is provided and includes a drum casing, which is essentially cylindrical in its basic form, with a central cylinder axis that forms an axis of rotation about which the drum can rotate. The drum casing has a tubular main casing portion with a first and a second front wall, which are connected to a first and second axial edge region of the main casing portion, and a reinforcing piece. The reinforcing piece surrounds the main casing portion over the outside circumference of the drum and counteracts the bulging of the main casing portion during the rotation of the drum under the influence of the centrifugal force, wherein the reinforcing piece has a cord-like component that encircles the outside circumference of the main casing portion.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a drum of a machine for the careful treatment of clothes, particularly of a washing machine, a washer-dryer, a tumble dryer or suchlike according to the pre-characterizing part of claim 1. The invention also relates to a machine for the careful treatment of clothes with a drum of this type.PRIOR ART[0002]EP 1,568,812 A2 and EP 1,505,188 A2 describe such a drum (200 in FIG. 12) of a washing machine according to the pre-characterizing part of claim 1, with a drum casing (400) which is in principle cylindrical in its basic form, with a cylinder axis forming the axis of rotation (A), about which the drum casing (400) can rotate. The drum casing (400) has a tubular main casing part (400a), with a first and second front wall (400b, 400c), which are connected to a first and second axial edge region of the main casing part (400a). The drum (200) also has at least one reinforcing piece that surrounds the main casing part ...

AI Technical Summary

Benefits of technology

[0009]The cord-like component can also be encircled in the pretensed state, around the outside circumference of the main casing part and fixed in this state in a relatively simple way without costly procedures. Due to the ductility of the cord-like component, it can also be easily mounted around the main casing part in several turns or passes and at one or more angles of tilt, and in this way it can reach, if necessary, different points on the outside circumference of the main casing part. This makes it possible to reinforce the drums in a simple and effective form and manner at the points that are subjected to particularly strong forces. The cord-like component can also be used for reinforcing drums of different sizes and / or drums of different types of machines for the careful treatment of clothes, without calling for an essential adaptation or modification of the cord-like component or for tools for fitting it. The production of the drum according to the invention is therefore simpler, more effective and more economic than that of known drums. Furthermore, the component acts by securely and reliably counteracting the undesirable bulging of the main casing part during the rapid rotation of the drum (for example at a speed of 1400 rpm or more).

[0013]The machine for the careful treatment of clothes basically makes it possible to achieve the same technical advantages as those set out above in connection with the drum according to the invention.

Problems solved by technology

Although the reinforcing strip (500) basically offers a high-quality solution, the production of the reinforcing strip (500) and the fitting of strip (500) in the drum are quite complicated and expensive as far as the production and fitting methods are concerned, and call for special tools and machinery.

Such reinforcing strips (500) therefore cannot be adapted to drums of different shapes and sizes, or can only be adapted to them by the use of extremely strong forces, for example in different washing machines or machines for the careful treatment of clothes.
