Definitions
- the invention relates to a device for cleaning lamella curtains, which are in the hanging and pushed together.
- Such devices are used in particular in the service area of room maintenance.
- Such devices are already known. In principle, they consist of a supply device and a spray device.
- the supply device has a mobile container which is equipped with some functional elements such as a pump, a filter, a heater and corresponding operating elements.
- the supply device is connected via one or more connecting lines to the spray device, which consists of a spray head with one or more nozzle strips and with a tubular jacket film.
- a device for cleaning is now known, in which the described supply device consists of a first and a second supply device.
- the first supply device has the basic equipment described above of a pure washing machine and is therefore filled exclusively with a washing liquid.
- the second supply facility is also formed as a mobile container and has only its own pump and a supply line which is connected to a distributor valve of the first supply device.
- This second supply device is designed as a dishwasher and is therefore filled with a washing liquid.
- the lamella curtain is first washed with the first supply device over a certain period of time.
- the washing liquid is conveyed into the spray head, where it emerges from the nozzles and runs down the slats and is collected again by the open container of the first supply device.
- the second supply device is connected to the first supply device.
- the rinsing liquid is then conveyed to the spray head via the distributor valve of the first supply device.
- the returning rinsing liquid also gets into the container of the first supply device.
- one of the two supply devices always remains unused, since the second supply device is not required during the washing process and the first supply device is bound during the washing process and cannot be used for another slat curtain.
- Another disadvantage is that after the termination of the Cleaning the washing and rinsing liquid is mixed in the container of the first supply device and therefore cannot be used for further cleaning.
- This device consists of a trolley, each with a storage container for washing liquid and rinsing liquid, as well as a pump and a heater.
- the trolley also has a common supply container which can be deposited on the ground level on site.
- the common supply container from the respective storage container is filled with the washing liquid or rinsing liquid. From here, the liquid is conveyed to the spray head and collected again as a dirty liquid.
- the supply container has to be raised above the level of the corresponding storage container and to be filled again with the clean rinsing liquid below the level of the other storage container.
- This fiddling with the storage container is cumbersome and thus unreasonable and, on the other hand, time-consuming and therefore expensive.
- the expenditure on equipment in relation to a cleaning process is too high.
- the possibility of using the same supply device for the washing process and for the rinsing process lowers the acquisition costs and simplifies the handling of this device.
- the device can be used variably and reduces the changeover times between the two cleaning processes.
- the rinsing liquid can also be preheated.
- the spray head is easy to handle and inexpensive to manufacture due to its simple construction.
- FIG. 1 shows a diagram of the subject matter of the invention
- FIG. 2 shows a diagram of the subject matter of the invention with an additional collecting container
- FIG. 3 shows a spray head in perspective
- FIG. 4 shows the spray head in a view
- FIG. 5 shows a nozzle in section.
- the device for cleaning a lamella curtain consists of a supply device 1 and a spray device 2.
- the supply device 2 is mainly formed from a mobile supply container 3, which for this purpose has two wheels 4 on one Axis and on the upper edge is equipped with a fixed handpiece 5 and a pivotable handpiece 6.
- the supply container 3 is kept open at the top and has a control panel 7, a driven pump 8, a double, overhead distributor 9 and a heating unit 10.
- the heating unit 10 is equipped with a temperature fuse switch, which in the unfilled state of the supply container 3 Heating unit 10 and the pump 8 keeps out of function.
- the pump 8 is connected directly to the distributor 9 via a pressure line 11 and to the heating unit 10 via a bypass line 12.
- the spray device 2 is composed of a spray head 16, a tubular jacket film 17 and two pressure lines 18.
- the jacket film 17 encloses the slat curtain 19 pushed together in a watertight manner.
- the spray head 16, as also shown in FIGS. 3 and 4, is formed from a cuboid base body 20 which is kept open at the bottom and on a short side. The surface above is provided with a slot 21, the open end of which lies on the open side of the base body 20. On the lower edges of the two long sides of the base body 20, a nozzle strip 22 is attached.
- the nozzle bar 22 is formed from a closed hollow profile body which is equipped with a connection for the pressure line 18 and a row of equally spaced nozzle bores 23. 5, the nozzle bores 23 are located on the respective inner side of the nozzle bar 22, have an exit angle of approximately 90 ° and are enclosed with notches 24 held horizontally.
- FIG. 2 shows an application when the supply device 1 cannot be pushed directly under the lamella curtain 19. This occurs when the slatted curtain 19 ends on a window sill, a radiator or on the floor. In these cases, the use of a separate collecting container 25 is necessary.
- This collecting container 25 has a .2-fold distributor 26, which is connected to the distributor 9 of the supply container 3 via a pressure line 27. Furthermore, the collecting container 25 is connected via a return line 28 to one of the connections 14 or 15 of the supply container 3.
- the lamella curtain 19 is first drawn together on a block.
- the spray head 16 with its pressure lines 18 is pushed over the lamella process 19 by the base body 20 with its slot 21 being guided past the vertical retaining rings of the lamellae and resting on the horizontal lamella carrier.
- the jacket film 17 is pulled over the lamella curtain 19 and attached to the spray head 16.
- the supply container 3 is placed under the slat curtain 19 and the pressure lines 18 are connected to the distributor 9 of the supply device 1. In this state, the jacket film 17 projects into the open supply container 3.
- the washing process is now started.
- the pump 8 conveys the washing liquid through the pressure line 11 via the distributor 9 into the pressure lines 18. Then the washing liquid emerges from the nozzle bores 23, hits the upper ends of the individual slats, runs down the slats and collects again in the supply container 3. In parallel to this circuit, washing liquid is pumped over the heating unit 10 on the short path and heated to a desired temperature.
- the pressure lines 18 are separated from the distributor 9 and the supply container 3 is pushed under a second lamella curtain 19.
- this second lamella curtain 19 is prepared and washed as just described.
- a second supply container 3 filled with a detergent is pushed under the first lamella curtain 19 and connected to the pressure line 18 of the first spray device 2.
- the rinsing process has the same technical sequence as the washing process. So the rinsing process can also be carried out with either cold or warm rinsing liquid.
- each lamella curtain 19 is cleaned. Since the washing process generally takes a longer period of time than the rinsing process and the preparation work for the washing process takes longer, for logistical reasons the use of two or more supply containers 3 for the washing process and the rinsing process is appropriate.
- the ratio of the supply containers 3 for the washing process and for the rinsing process is determined solely by the selected or required washing and rinsing times.
