Electric window cleaner

The invention relates to a window cleaning device hit a cleaning head that can be brought into contact with the surface to be cleaned.

Known window cleaning devices of this type have one the glass pane movable cleaning head, which consists of a Standing container is supplied via a hose connection cleaning liquid, the cleaning liquid by means of an elastic sealing lip stripped from the window and over another hose line is led back to the jar. This device is quite complex.

The object of the invention is to create a window cleaning device of the type described at the outset, which is easy to use, has a simple structure and is inexpensive to manufacture.

This object is achieved according to the invention in that the cleaning head has a heated work surface that can be brought into contact with the surface to be cleaned and covered with a cleaning cloth. The working surface is preferably be heated to about 100 ⁰ C to bring the moisture to a moistened cleaning cloth for evaporation. The steam loosens the dirt which is then picked up by the cleaning cloth. After cleaning a more or less large window area, depending on the degree of soiling, the cleaning cloth is exchanged for a new one.

The cleaning cloth stretched on the tile work surface is advantageously moistened several times with a new cloth before being replaced. The device described has a device-wise significantly less effort than those described above known window cleaning device and is very effective and easy to use.

To attach a cleaning cloth to the cleaning head, the latter can have a substantially circumferential groove as well as one in the Have a groove engaging tightening band for fixing the edge areas of the cleaning cloth. With a suitable design of the groove becomes smooth by applying the tension band to the cleaning cloth stretched across the work surface.

The cleaning device advantageously has an auxiliary device to apply and / or moisten the cleaning cloth. in fact, this can be one to accommodate the cleaning surface Have dimensioned shaft and a clamping device for the tensioning band that preferably surrounds this shaft. Further can the auxiliary device a preferably arranged in the shaft humidifying device z. B. in the form of a sponge! to have a cleaning cloth. :

Veiter, the auxiliary device can have a storage space for cleaning cloths, which is accessible by removing a bottom cover or opening a side flap. Such: auxiliary device combined more or less convenient functions in itself, thus reducing the number in the window \ cleaning tools or equipment required.

The cleaning head 2 shown in FIGS. 1 to 3 has a sole 4 designed as an aluminum injection-molded part the inside of which by means of clamping screws 6, leaf springs 8 and a

Pressure plate 10, a surface heating element 12 is held in contact. Two of the clamping screws 6 are made longer and are also used to attach a cover 14 made of heat-resistant plastic to the back of the sole 4. On the Pressure plate 10, a temperature controller 16 is arranged.

A handle 18 used for handling the cleaning head has an electrical connection line 20 and a handle on its front end arranged cross tube 22, with which it is pivotably mounted in the cover.

The sole 4 has a wedge-shaped tapering outward circumferential edge portion 26, which together with a tapered lower edge portion 28 of the cover 14 one around the Groove 30 running around the cleaning head 2 forms. When cleaning the window, the outside forming a work surface 32 is applied the sole 4 stretched a moistened cleaning cloth 34 by a tension band in the form of a revolving spiral spring 36 clamps the edge areas of the cleaning cloth 34 in the groove 30.

In Figures 4 to 7 is an auxiliary device for application and wetting the cleaning wipes shown, which has a base body 40 with a top cover 42 and a Lower cover 44 is provided and together with the lower cover 44 a storage space 46 for unused cleaning dishes forms. The lower cover 44 can be removed when in use and have a sufficiently high side edge to be used as Serving storage bowl for the unused cleaning wipes. Buttocks of a modified embodiment, not shown, can the storage space 46 have a lateral closure flap.

The base body 40 has in its central area an elongated trough or a shaft 48 for receiving a moistened Sponge 50 on. The side wall 52 of the chute 48 faces in its uppermost area along the long sides of the shaft a shoulder 54, the vertical depth of which is just sufficient, around the spiral spring inserted therein as shown in FIG

withhold when these hooked under outwardly projecting hooks 56 on the narrow sides of the shaft and thus is stretched downwards. Starting from the shoulder 54, the edge region of the base body 40 rises towards its outer longitudinal sides towards to merge into a paragraph 60 for receiving the upper lid.

FIGS. 8 to 10 show the use of the auxiliary device described above when applying and moistening the cleaning cloths. To apply a new cleaning cloth, the spiral spring 36 forming the tensioning band is first hung under the two hooks 56 ar the end faces and then stretched along the long sides behind the shoulders 54 (FIGS. 6 and 7). A fresh cleaning cloth 34 is then placed on the auxiliary device 39 and the cleaning head 2 is held centrally over the shaft 48 with the sponge 50 and then pressed down into the position shown in FIG . The spiral spring 36 is then released from the hooks 56 by hand, whereby it also jumps down from the shoulders 54 and presses the cleaning cloth into the circumferential gutter 30 of the cleaning head and thus tightly clamps it around the sole 4 with the work surface 32. By pressing the cleaning cloth against the moistened sponge 50, which exerts a counter-pressure effect due to its elasticity, the cleaning cloth 34 is moistened during this process at the same time.

Various textiles, sponge cloths or nonwovens can be used as cleaning cloths.
