Abstract

The invention relates to cycle washing machines for the disinfectant treatment of laundry, consisting of lined-up in the axial direction treatment segments. The aim of the invention is therefore to develop a known clock washing machine so that consequential damage is avoided as a result of Abflieszens not germ-free wash liquor from the clock washing machine. The invention has for its object, taking into account the variability of the number of processing compartments with low construction costs to create a clock washing machine with reliable disinfection of the laundry and germ-free wastewater. This object is achieved according to the invention by the fact that at least one drum is imperforated in the direct current range and is thus liquid-tight, and that the transfer device of these drums likewise has no perforation. Housing the segments with unperforated drums are subjected to a liquid medium and there is an indirect heating of the drums, and preferably the erfindungsgemäisz the hot, exiting from the final wash clearwash region wash liquor is used.

Description

Title of the invention:

Clock washing machine for disinfecting laundry

Field of application of the invention:

The invention relates to cycle washing machines for the disinfection treatment of laundry, consisting of lined-up in the axial direction treatment segments with soaking, washing and rinsing zones.

Characteristic of the known technical solution ;

In the WP DO 6 17218 284 a Taktwaachmaschine for disinfecting treatment is described _s in which the laundry from the input side starting the individual segments cyclically through and passes through the treatment areas soaking, washing with chemical and thermal disinfection and rinsing happens. Here, in the area of soaking and prewashing, the DC process and in the area of clear washing and rinsing, the countercurrent process is realized. Following the DC region or the countercurrent region, a drain is in each case attached, through which the treatment liquor leaves the clock washing machine. To realize the chemical disinfection in the DC range, the laundry and treatment liquor remains for a certain time

certain temperature "with the addition of disinfectant detergents"

At o.g. Invention has been found in the field of chemical disinfection following disadvantage:

During the BeladeVorganges enters the laundry with the one-rinse water, which is also used as soaking water and prewashing, highly germ-laden in the first segment. As a result of this addition of liquid, in the first segment there first occurs a rise in the level, which normalizes as a result of the overflow and adjusts to the required level. The same happens in the second and each further segment until the outflow of the DC region. Due to this possible flow of a part of the highly germ-laden Einspülwassers over the overflows to the drain in a much shorter time than the cycle time, the transport of not killed germs on this way is possible because the exposure time of the disinfectant was exceeded.

This does not ensure that completely germ-free off, water leaves the clock washing machine to avoid environmental damage had to be collected by additional effort in an additional container, the wash liquor of the DC area and rendered germ-free by the addition of disinfectant v / ground.

Object of the invention:

The aim of the invention is therefore to weiterzuentwiekeln a known clock washing machine that consequential damage is avoided as a result of draining non-germ-free wash liquor from the clock washing machine.

Explanation: the essence of the invention:

The invention has for its object, taking into account the variability of the number of processing compartments with low construction costs to create a clock washing machine with reliable disinfection of laundry and germ-free wastewater «

This object is achieved in that at least one drum unperforated in the DC region and thus formed liquid-tight and that the Übergäbevorrichtung these drums also have no perforation.

According to the invention, the housings of the segments are loaded with imperforate drums with a liquid medium in order to achieve indirect heating of the liquor within the drums via the drum casing. For the application of the housing of the imperforate drums with liquid heating medium, preferably and according to the invention, the hot vaporizing liquor emerging from the final wash zone of the countercurrent process is used wholly or partly.

To dispense the disinfectant coming from the dosing station disinfectant line opens in the input tray of the laundry.

The invention ensures that a reliable disinfecting treatment of the laundry takes place and that the treatment liquor leaves the cycle washing machine absolutely germ-free both from the direct current region and from the countercurrent region. Thus, on the one hand, the carryover of living pathogens, e.g. On the other hand, further elaborate measures are unnecessary from germ-freeing the effluent 'wash liquor.

Embodiment:

Further features of the invention will be explained in more detail below with reference to an embodiment. The drawing shows a longitudinal section of a clock washing machine according to the invention as a schematic representation.

This consists of arranged within a housing 16, juxtaposed in the axial direction and combined into a rotatably mounted washing drum segments The separation of the pure from the impure side takes place through the partition 6. In the segments 4.1, 4.2, 4.3, 4.4 and 4.5 is the DC method and in the segments 4 x 6 to 4 x 12, the countercurrent process is realized.

About the input hopper 1, the laundry enters the clock washing machine, already here is added via the disinfectant line 2, the disinfectant from the dosing 3 the laundry items. In segments 4.1 to 4.4 are the unperforated drums 17.1, 17.2, 17.3 and 17.4. Together with the soaking water, which passes from the reservoir 11 via pump 12 and Einspülleitung 13 into the hopper 1, the laundry item is conveyed into the drum 17.1. This drum is imperforate, the entire liquor acts at 35 ⁰ C and added disinfectant on the laundry to be treated. An advance of germs is not possible, since there is no fluent running of the plot. Only after completion of the full cycle time, the fleet is promoted together with the laundry items in the drum 17.2, which is also unperforated. In the cases 16.2, 16.3 and 16.4 is a liquid heating medium to heat the liquor in the associated drums 17.2, 17.3 and 17.4 to the required Flottentenperatur of 60 ⁰ C for chemical disinfection.

This heating medium is preferably and according to the invention from the segment 4 »6 via the drain 14 and 14a via the line branched off liquor from the countercurrent at a temperature of 85. ⁰ C ITichticht not required for heating liquor is discharged via outlet 14b. For the starting operation and insufficient heat supply through the fleet via line 14 a is a heating and temperature control device 21 is present. At the end of the cycle time, the laundry item with the exactly assigned wash liquor is conveyed through the imperforate transfer device to the unperforated drum 17 * 3 and after the cycle time has ended in the drum 17.4 *

By the joint transport of laundry items and associated liquor and the corresponding disinfectant is guaranteed that the contact time of the disinfectant on laundry and wash liquor is accurately maintained and no germ-bearing liquor components can get into the drain 15 of the DC region by detours ·

After the laundry and liquor have been treated in the unperforated drum 17.4, the laundry with the entire associated treatment liquor is conveyed into the drum 17.5, which is provided with a perforation in a known manner.

Here, the treatment liquor passes through the perforation in the housing 16.5 and, leaves via drain 15 completely germ-free, the DC region of the clock washing machine.

Leakage water is passed in a known manner via the leak water line 8 and 9 Leckwassersammelleitung in the sump 11 and the fan 5 a certain air circulation is achieved, the fresh water supply 7 and the line for diverted rinsing water 10 are also mounted in a known manner.
