Abstract

The automatic window cleaning system comprises a computer-controlled box (9) which moves up and down on racks (4) on either side of the window. This carries a squeegee (6) and rotating brush (7) and a sucker (8) for removing dirty water.

Description

The The invention relates to an automatic window cleaning system for vertical and sloping Windowpanes.

Usually be windows by washing with water and detergent as well followed by Wipe cleaned to remove cleaning fluid. at a manual solution this is usually done through one with cleaning fluid soaked body (e.g., sponge) and then by a flexible wiper element (e.g., rubber scraper).

It Automatic cleaning devices have also been described e.g. with robot control equipment the entire facade of a skyscraper should clean.

These solutions required however - besides the complicated computer control - large management equipment which the cleaning system precise from window to window. In addition to the optical disorder of Facade, which through this large management systems was caused this to the disadvantage that already at a low malfunction the system does not clean the entire façade surface could.

at other known automatic cleaning devices is a on ropes hanging rack proposed, on which the cleaning head is attached. On the Frame are the necessary aggregates such as water tanks, Power generators, lines, etc.

The Rack is now with ropes on a crane or on a trolley suspended which can be moved on rails, which are located on the roof of the building. The crane moves Now the frame from window line to window line, so that there the cleaning operations are carried out can.

Here the same disadvantages as in the above-described solution can be seen.

Of the solution according to the invention now the task is based, an automatic window cleaning system to create the time-consuming, tedious manual window cleaning replaced, provides a robust and not prone to failure solution, without the facade or the glass roof surface visually disturbing and by miniature construction in the window frame or in the shutter area is integrable and above as a retrofit kit is usable.

The inventive task is solved by that pro Window unit an autonomous window cleaning system exists, wherein the functional elements are integrated in a system box and toothed racks placed to the right and left of the window pane for cleaning the glass surface can be driven up and down.

at a preferred solution according to the invention the guide rail attached to the window frame, alternatively, the attachment here also be made on the window reveal or - depending on Window system - too be integrated in the roller shutter box.

at inventive developments is the dirty water tank as well as the detergent container also integrated in the roller shutter box.

Other Solutions of the invention see the Installation of the two containers accessible in the wall area from the inside of the house or outside the house.

To the Transport of cleaning fluid to the cleaning brush is a capillary tube provided, which is connected to the detergent container and a preferably small amount of cleaning fluid applied to the preferably rotating cleaning brush. The rotatory Movement of cleaning brush is provided by the immanent electric drive.

at further variants of the invention can the cleaning brush be subjected to a horizontal intermittent cleaning movement, wherein the rotational movement and the horizontal movement also superimposed can be.

The lateral racks, which for the realization of the cleaning stroke are required to be fixed and guided by a bezel Guide rail, so that the Movement dream is mechanically predefined. To improve the Optics and prevention of corrosion is involved in a solution according to the invention Anodized aluminum or alternatively corrosion-resistant plastics worked.

A inventive solution shown in the drawings. Show it:

Here is a top view of the windowpane ( 2 ) with window frames ( 1 ) as well as the system box ( 9 ) recognizable. On the right and left vertical frame menteil ( 1 ) is ever a rack ( 4 ) and the associated gear ( 10 ). The dirty water tank ( 13 ) as well as the detergent container ( 14 ) can be accommodated in the masonry.

On the windowpane ( 2 ) sits the rubber lip ( 6 ), as well as the cleaning brush ( 7 ) as well as the dirty water extractor ( 8th ). The wetting of the cleaning brush ( 7 ) with the cleaning liquid from the detergent container ( 14 ) via the capillary tube ( 11 ) and ends in the capillary tube ( 12 ). The toothed rack ( 4 ) is bordered by the cover strip with guide rail ( 5 ) to improve the appearance and precise guidance of the gear ( 10 ).
