Cleaning system designed to be installed on a surface that is exposed to poor weather conditions

Abstract

The invention teaches a cleaning system designed to be installed on a surface exposed to poor weather conditions or on a roof. Said system comprises a plurality of reactive surfaces consisting of a metal surface, preferably containing copper, said surface producing, combined with water, compounds having a cleaning, preferably fungicidal and/or bactericidal, action. When they are dissolved, said compounds can cover the roof at least partly. The inventive system is characterized in that it comprises at least one partly metallic layer, at least one partly metallic layer arranged on the surface to be cleaned and at least one partly metallic intermediate layer partly, at least two layers being separated from one another over at least part of their surface by spacers such that between the coats gaps are formed wherein natural moisture can infiltrate.

1 . A Cleaning device ( 1 ) for fitting to a surface exposed to the weather, in particular a roof, a roof surface, a solar system surface or a facade, the cleaning device having reactive surfaces, which are arranged in layers and have a metallic, preferably copper-containing, surface which, in conjunction with water, generate cleaning, preferably fungicidal and/or bactericidal compounds which, dissolved in water, can at least partly wet the roof, characterized in that at least one outer layer ( 1   .n ), a lower layer ( 1 . 1 ) and at least one intermediate layer ( 1 . 2 - 1   .n - 1 ) are provided, at least two layers being separated from each other, at least over a sub region of their area, by spacers ( 2 ) in such a way that spaces ( 14 ) are formed between the layers, into which natural moisture, in particular rainwater, can flow and can be rinsed out again.

       6 . The cleaning device according to  claim 1 , characterized in that the at least two layers ( 1   .x ) are arranged conically in relation to one another with the aid of the spacers ( 2 ).  
   
   
       7 . The cleaning device as recited in  claim 1 , characterized in that the spacers ( 2 ) between two layers touch a layer ( 1   .x ) only in the manner of a point or in the manner of a line.  
   
   
       8 . The cleaning device as recited in  claim 1 , characterized in that the spacers ( 2 ) represent part of a deformed layer ( 1   .x ) and are preferably produced by a punching tool.  
   
   
       9 . The cleaning device according to one  claim 1 , characterized in that at least one layer ( 1   .x ) has a bead ( 8 ) and/or hinge for at least one layer ( 1   .x+ 1) arranged above it, which supports the at least one layer ( 1   .x+ 1) arranged above it at the ends, preferably at least sectionally in the manner of a line.  
   
   
       10 . The cleaning device are recited in  claim 1 , characterized in that it is formed as a roof ridge slab.  
   
   
       11 . The cleaning device as recited in  claim 1 , characterized in that its contour and/or surface are matched to known roof slabs and roof tiles.  
   
   
       12 . The cleaning device as recited in  claim 1 , characterized in that the spacers ( 2 ), at least in the upward region, effect a minimum spacing of preferably more than 1 mm, preferably 2 mm to 3 mm, in which capillary action with respect to penetrating water can be disregarded.  
   
   
       13 . Cleaning device according to one of the preceding Patent  claims 1  to  12 , characterized in that at least two intermediate layers ( 1 . 2 - 1   .n - 1 ) are provided, preferably exactly two intermediate layers ( 1 . 2 ,  1 . 3 ).  
   
   
       14 . The cleaning device a as recited in  claim 1 , characterized in that all the layers ( 1   .x ) are separated from one another by spacers ( 2 ).  
   
   
       15 . The cleaning device as recited in  claim 1 , characterized in that the spacers ( 2 ) have different heights.  
   
   
       16 . The cleaning device as recited in  claim 1 , characterized in that, at least between two layers, the water inlet gap ( 6 ) is larger than the water outlet gap ( 12 ).
