Description

The invention relates to a device for washing textiles, in particular items washing system, with a subdivided into individual chambers washing drum, wherein the washing drum is at least partially surrounded by an outer drum. Furthermore, the invention relates to a method for manufacturing a corresponding device.

Devices for washing textiles of the type mentioned are known for many years from practice. Only by way of example on the DE 39 03 458 C2 directed. The known device comprises an open at both ends, horizontal, rotatably mounted and divided into individual chambers washing drum, which is surrounded by a wash liquor receiving the washing tub. The washing process is carried out by reversing partial rotations of the washing drum, the laundry promotion from chamber to chamber is carried out at a full rotation of 360 degrees in one direction.

The length of the washing drum requires both the clock and the capacity of the post-washing system, in practice washing drums with a length of over 10 m are quite applicable.

The known washing drums have the disadvantage that they are extremely complicated and time-consuming in production. Once the desired length of the washing drum has been determined, the "inner workings" - such as, for example, drivers, dividing walls, blades - are placed in a tube corresponding to the length of the washing drum. For this purpose, the workers have to crawl into the washing drum and do the necessary work in a confined space. In addition to the high expenditure of time and the associated costs, this work also carries health risks for the workers who have to move in the interior of the pipe over a long period in a stooping position during welding work. Another disadvantage is that the laundry drums are made individually according to customer requirements time, from order intake to completion, and finally to deliveries.

Further, by way of example, the DE 23 45 943 A1 and the DE 25 27 502 A1 directed.

The present invention is therefore based on the object, a device for washing textiles and a method for manufacturing such a device of the type mentioned in such a way and further develop that the device by means of simple design means with little effort and time individual wishes are made accordingly can.
The above object is solved by the features of claim 1. Thereafter, the generic device for washing textiles is characterized in that the washing drum of prefabricated modules, which are interconnected, is constructed.

In accordance with the invention, it has been recognized that the construction of the washing drum from prefabricated modules - according to the "modular principle" - the time from order to delivery can be significantly reduced. Due to the modular design, the length of the post-washing system and thus the capacity and timing in the simplest way - according to the customer's request - be varied. Another advantage is that the production of the modules does not necessarily have to be done at the place where the washing drum is finally assembled. In terms of module production, therefore, there is the possibility of "outsourcing", ie to make the modules cheaper, for example, abroad. The modular design also has the consequence that the pipe sections to be machined are now much shorter. The resulting work can be done from the outside, which improves the working conditions and the time required for this work is significantly lower
Advantageously, the washing drum comprises at its one end an input module to which a raceway module connects. The raceway module will follow at least a center module, which again a raceway module and finally a dispensing module are arranged downstream. The length of the washing drum is determined by the number of middle modules. Furthermore, it is conceivable that the washing drum only at one of the two ends has a raceway module or that between two middle modules also another raceway module is attached. In a particularly advantageous manner, the lateral surface of the center modules is partially or completely perforated. In a preferred embodiment, the lateral surface in the washing area on a hole, while in the transport area, the lateral surface is not perforated.

In order to keep the textiles during the reversing movement of the washing drum during the washing process within a central module, the central modules have at their base a partition that includes a passage opening in the transport area to promote the textiles after a completed washing process. Depending on whether the center module two functional chambers - for example, prewash and main wash - separated or not, the partition is designed with or without holes.

With regard to the connection of the individual modules with each other, there are several possibilities. In a particularly advantageous manner, the individual modules are connected to each other via welds or welds. Furthermore, it is conceivable to glue the modules together or to apply them via clamping devices, i. to connect with each other by tension. In a further advantageous manner, the individual modules can have a flange in their connection region, so that they can be screwed together.

In order to "hang" the fabrics during the reversing partial rotations that the washing drum performs during the washing process to a certain height, so that they are twisted through, the modules have to "hang" the drivers so that they are twisted through, the modules have drivers , which are preferably mounted in the form of a rib radially on the drum inner wall.

With regard to the axial conveyance of the textiles from the input module through the washing drum to the output module, the individual modules have blades on, which promote the textiles in the axial direction with a rotation of the washing drum by 360 degrees.

There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the claims subordinate to claim 1 and on the other hand to refer to the following explanation of a preferred embodiment of the invention with reference to the drawings. In conjunction with the explanation of the preferred embodiment of the invention with reference to the drawing, generally preferred embodiments and developments of the teaching are explained. In the drawing show

Fig. 1 shows in a simplified schematic representation of the individual parts of the washing drum 1, which is surrounded by an outer drum, not shown. The washing drum 1 has at its one end an input module 3 for charging with the textiles to be washed and at the other end an output module 5, where the washed textiles are removed. In the operating state, the washing drum 1 is mounted on the raceway modules 4 and not shown drives, which act on the raceway modules 4 rotatable in both directions. The middle region of the washing drum 1 is formed by the central modules 2, which divides the washing drum 1 into functional chambers. This can, for example Chambers for prewash, main wash, rinsing or possibly strengthening the textiles be present. In the embodiment chosen here, the middle region of four central modules 2 is formed, wherein the number of center modules 2 can be varied as desired. The number of center modules 2 significantly determines the clock and the capacity of the post-washing system.

in Fig. 2 the individual modules (2-5) are connected to each other - for example via welds, by gluing, via clamps or a flange connection - so that they form the washing drum 1.

At the in Fig. 3 shown middle modules, the partition wall 7 is not perforated, so that the modules 2 are suitable to separate, for example, the pre-wash chamber of the main laundry chamber. Furthermore, it can be seen that the lateral surface 6 has a perforation in the washing area and is unperforated in the transport area. In the transport area, the passage opening 8 is further educated, through which the textiles are conveyed by means of the blades 10 in the axial direction. To "hang" the textiles during the reversing movement of the washing drum 1 during a washing process to a certain height, so that they are whirled through, drivers 9 are provided.

If one of the chambers - for example, to rinse - composed of several central modules 2, so as to achieve the desired length, find the center modules 2 Fig. 4 Application. Here, the partition wall 7 is perforated, so that wash water or wash emulsion can flood through the entire chamber and does not remain in the individual center modules 2. Otherwise this corresponds to in Fig. 4 shown center module 2 in its embodiment the in Fig. 3 shown center modules 2.

With regard to further features, which can not be inferred from the figures, reference is made to avoid repetition to the general part of the description.

Finally, it should be noted that the embodiment discussed above is merely illustrative of the claimed teaching, but is not limited to the embodiment.
