Description

The invention relates to a cleaning device for tarpaulins surfaces with a pumping device for conveying a cleaning liquid from a tank and targeted delivery via a spray head the area to be cleaned with a pump actuation on a work handle and a cleaning plate hinged to it.

For cleaning or maintaining surfaces, in particular of floors, tiled walls Windows, etc., it is necessary in addition to the necessary moisture also a cleaning liquid applied. Applying the cleaning liquid to the one to be cleaned area still takes place as a rule in that this cleaning liquid a tank or container is poured uncontrollably onto the surface to be cleaned and then a wipe or sponge attached to a corresponding device on the surface to rub.

In order to facilitate this work process and to ensure a dosed application of the cleaning liquid, is in the DE-OS 19 34 380 describes a cleaning device in which the cleaning liquid can be poured into the work handle designed as a tank and is sprayed by the latter via a pump device in the handle through a spray head into the area of a cleaning plate attached to the work handle. The pump device is designed as a deformable hollow handle. However, it has been shown that this cleaning device cannot meet the expectations of housewives. The transfer of the cleaning liquid into the handle designed as a tank is too cumbersome, the handle itself becomes too voluminous and the handling of the pump in the form of an elastic handle contradicts the ergonomic requirements for a woman's hand.

Another cleaning device in this Art became known through the German utility model 1 755 947, in which the pumping device with tank on the work handle respectively are attached to the cleaning plate. This has the disadvantage that the cleaning device is unwieldy will and in its aesthetic Appearance does not meet the requirements of a modern household.

The object of the invention is a cleaner according to the generic term of claim 1 to create that with easier targeted dosing Cleaning fluid is easy to use and easy to produce, taking the cleaning liquid not cumbersome decanted must become.

This task is done with the characteristic Features of claim 1 solved. By integrating the pumping device and the actuation connection a pleasing appearance of the cleaning device is achieved with the handle in the work handle. The tank for the cleaning liquid can be favorable in terms of focus nearby the cleaning plate can be provided so that an ergonomically safe Handling the cleaning device guaranteed is.

In a further embodiment of the invention is the housing the pump device at its lower end at the same time Bracket designed to hold the cleaning plate. This reduces the Assembly effort and thus the manufacturing costs. At the same time in this housing the spray head integrated so that none disturbing Parts protrude.

In a further embodiment of the invention is on this case the adapter for a container for the cleaning fluid (Tank) molded. This adapter consists of a tubular collar, into which the neck of the tank can be inserted and locked. At the same time, a spring-loaded valve and one that influences it Mandrel provided, optionally the mandrel on the adapter and the valve can be provided on the tank or vice versa.

The invention is based on the two Drawings closer explained. Show it:

1 a schematic representation of a cleaning device and

2 a detailed embodiment of the housing with tank in section.

The cleaning device according to 1 consists essentially of a tubular work handle 1 with one hand 2 at the upper end 3 , a pumping device 4 with a cleaning plate 5 at the bottom 6 and a tank 7 to absorb the cleaning liquid.

The pumping device 4 is via an operating lever 8th in the handle 2 activated. The operating lever 8th is over a peg 9 connected to the pump device and is by a spring 10 in his working position, as in 1 shown, held. The pole 9 is at least about sections in waves 11 for guidance on the inner wall 12 of the handle 1 educated.

The pumping device 4 is in one case 13 arranged that in the lower end 6 of the handle 1 is inserted. To this case 13 is an adapter 14 to hold the tank 7 and a bracket 15 to accommodate the cleaning plate 5 formed.

Of course the tank can 7 also in a different way on the work handle 1 be attached and an adapter in the form of a line 16 with the pumping device 4 , as in 1 shown, be connected. The Tank 7 can be designed as a refill tank or as a disposable bottle. The tank is preferably arranged essentially in the working direction, ie with its main volume fraction, in front of the stem. This results in a cheaper center of gravity and thus better handling of the cleaning device, and the path from the tank to the nozzle can be kept very short in this way, so that on the one hand less material for the line of Cleaning fluid is required and on the other hand there is only a minimal path pressure loss.

The pumping device 4 consists essentially of one in a cylinder 17 , the part of the housing 13 is guided piston 18 that has a piston extension 19 with the pole 9 is connected to an inlet valve 20 between the tank 7 and the cylinder 17 and an exhaust valve 21 between the cylinder 17 and also in the case 13 integrated spray head 22 , The spray head 22 is via a pressure line 23 with the cylinder 17 and the tank via a suction line 16 ( 1 ) respectively 24 ( 2 ) with the tank 7 connected.

In the embodiment 2 is the tank 7 over a neck 25 with a collar 26 that to the adapter 14 or the housing 13 is molded, connected snap. The collar 26 is with the suction line 24 connected and has a thorn 27 that one over a spring 29 pressurized valve 28 when inserting the tank 7 into the adapter 14 or the collar 26 opens.

During the cleaning process, the cleaning device is guided over the surface to be cleaned with the cleaning plate, which can be provided with a clamp for cleaning wipes or with a sponge. If there is a corresponding accumulation of dirt, the operating lever 8th on the handle 2 tightened, causing the rod to become 9 , and thus the piston 18 in the cylinder 17 in the direction 30 moved down and in the cylinder 17 builds up a pressure. This pressure opens the outlet valve 21 , so that the cleaning liquid over the spray head 22 in front of the cleaning plate 5 is sprayed. Will the operating lever 8th released again, presses the spring 10 the pole 9 with piston 18 against the direction 30 up, the inlet valve 20 opens and sucks via the line 16 or suction line 24 Cleaning liquid from the tank 7 in the cylinder 17 so that liquid is available again for the next cleaning or spraying process. Spraying is preferably carried out at a minimum pressure, advantageously 4 bar, the pump sealing off at a pressure below the minimum or limit pressure, here 4 bar, so that there is no rinsing or dripping of cleaning fluid, but instead the detergent always flows out vacuum.
