Drum for a laundry treatment machine

Abstract

In order for a drum (1) of a laundry treatment machine to generate a different effect in accordance with the direction of rotation of the drum (1) which is rotatably mounted within a housing of the laundry treatment machine and has at least one bottom disk (3) and a jacket (5) that are individually or jointly provided with a curved structure, the flood holes should also be arranged and distributed in a way that is more gentle to the laundry than in prior art. Furthermore, the structure should have an inherent scooping effect which allows water to be scooped from an amount of water stored at the bottom of the lye container when the drum rotates and be conducted onto the laundry from above. For this purpose, the curved structure consists of at least two rows of prism-type embossings (6) which encompass at least part of the drum (1) and have a substantially rectangular base. The prism surface (10) oriented in the circumferential direction (7) of the drum (1) extends at a steep angle while the opposite surface (9) extends at a flat angle relative to the drum jacket (5). The lateral faces (25) of the embossings extend at least nearly at 90 degrees from the jacket (5). Flood holes (8) required for treating the laundry are located within the steep surface (10).

Description

technical field [0001] The invention relates to a drum for a laundry treatment machine, wherein the drum is rotatably mounted in a housing of the laundry treatment machine and has at least one chassis and a sleeve, wherein the chassis and the sleeve are individually or together provided with a curvature Structure. Background technique [0002] A roller of this type is known from patent publication DE 10 2006 010 179 A1. The individual elements with a curved structure are each arranged circumferentially aligned within the drum sleeve, the contours of which extend along the drum sleeve alignment forming a surface with a plurality of arc-shaped borders extending continuously to each other and having only a single symmetry axis, which axis of symmetry extends at least approximately in the circumferential direction of the roller sleeve. Attached to the wall of each element, said wall being raised highest relative to the cover of the drum sleeve, is the exchange between the insi...

AI Technical Summary

Problems solved by technology

The roller known from DE 10 2006 010 179 A1 cannot achieve this effect to a suitable degree because the number of elements is too low for this purpose

On the other hand, roller sleeves with a purely corrugated and / or ribbed structure are not sufficiently stable and also pose major problems from a manufacturing point of view, because sleeve plates with a corrugated or ribbed structure Can only be attached to the bottom of the drum with difficulty
