Device for the wet treatment of items to be washed

Abstract

An inline washing system to be formed from a tunnel-type washing machine (10) which only washes the items of laundry. Rinsing and also water removal are then performed in the downstream water-removal press (18). It has been found that the rinsing performance is better and fresh water can be saved as a result of this. It is therefore also possible to wash relatively small amounts of laundry using a tunnel-type washing machine (10) in an economical manner because the tunnel-type washing machine (10) can be designed without a rinse zone.

Description

STATEMENT OF RELATED APPLICATIONS[0001]This application is a division of and claims the benefit of U.S. patent application Ser. No. 11 / 815,717 having a 35 USC 371(c) date of 21 May 2008, which is the US National Phase under Chapter II of the Patent Cooperation Treaty (PCT) of and claims the benefit of PCT International Application No. PCT / EP2006 / 000433 having an International Filing Date of 19 Jan. 2006.1. TECHNICAL FIELD[0002]The invention relates to a method for the wet-treatment of items of laundry in which the items of laundry are washed in a washing device and water is at least removed in at least one downstream water-removal device, and to an apparatus for the wet-treatment of items of laundry.2. RELATED ART[0003]Liquids are used for the wet-treatment of laundry, in particular for washing and rinsing items of laundry, with said liquids substantially being fresh water in the case of rinsing. The rinse result is also dependent on the quantity of fresh water used. However, for en...

AI Technical Summary

Benefits of technology

[0005]The object of the invention is to provide a method and an apparatus for the wet-treatment of items of laundry in an economical manner. The method and the apparatus should preferably also permit economical wet-treatment of relatively small batches of laundry.

[0006]One method for achieving this object is a method for the wet-treatment of items of laundry in which the items of laundry are washed in a washing device and water is at least removed in at least one downstream water-removal device, comprising the steps of both (a) rinsing the items of laundry and (b) removing water from the items of laundry in the at least one water-removal device, wherein the water-removal device is a water-removal press. Since the respective water-removal device is in the form of a water-removal press and not only removes water from the laundry but also rinses the laundry in the respective water-removal press, the rinsing process can be transferred from the washing device to the water-removal device. As a result, the rinse zone can be omitted from the washing device, as a result of which the washing device can be of simpler construction, in particular takes up less space. Above all, the washing device no longer has to be designed to generate a counter-current of the treatment liquid. Since the respective water-removal press is required in any case, the method according to the invention provides a space-saving inline washing system overall. In addition, it has surprisingly been found that the laundry can be rinsed in water-removal presses far more effectively than in the washing device. In this way, the rinsing performance is improved and fresh water is saved.

Problems solved by technology

As a result, the known tunnel-type washing machines have a relatively complicated structure, and so tunnel-type washing machines are used only where large amounts of laundry are to be washed.

On account of the at least three successive zones, the drum has to have a relatively long length, as a result of which the known tunnel-type washing machines take up a great deal of space in the laundry facility.
