Cooking appliance door with an inner borosilicate glass door pane and cooking appliance with said door

Abstract

The cooking appliance door has an inner door pane made of borosilicate glass and a paint layer applied to a surface on one side of said inner door pane. The paint layer is made by printing high-temperature-resistant non-enamel paint with an organic or inorganic binder on the surface on the inner door pane, preferably by a screen printing technique. In order to prevent the deformation of the printed inner door pane during hardening, the paint layer consists of a plurality of individual paint spots with a predetermined maximal geometric shape. The individual paint spots are arranged in a predetermined pattern with a predetermined paint-free spacing from each other on the inner door pane.

1 . A cooking appliance door comprising 
 an inner door pane comprising a borosilicate glass;    at least one paint layer applied to a surface on one side of said inner door pane, wherein said at least one paint layer comprises a high-temperature-resistant non-enamel paint with an organic or inorganic binder and said at least one paint layer consists of a plurality of individual paint spots with a predetermined maximal geometric shape, wherein said individual paint spots are arranged in a predetermined pattern with a predetermined paint-free spacing from each other on said surface on said one side of said inner door pane.    
     
     
         2 . The cooking appliance door as defined in  claim 1 , wherein said paint spots are arranged in a grid pattern comprising a plurality of rows arranged one above the other.  
     
     
         3 . The cooking appliance door as defined in  claim 1 , wherein said predetermined pattern of said paint spots is a grid-structured raster.  
     
     
         4 . The cooking appliance door as defined in  claim 3 , wherein said grid-structured raster of said paint spots comprises a plurality of rows of said paint spots arranged one above the other and neighboring rows of said paint spots are displaced with respect to each other by a predetermined displacement.  
     
     
         5 . The cooking appliance door as defined in  claim 4 , wherein said predetermined displacement amounts to half a raster line spacing.  
     
     
         6 . The cooking appliance door as defined in  claim 1 , wherein said paint spots have different geometric shapes and are arranged in an irregular line-shaped pattern.  
     
     
         7 . The cooking appliance door as defined in  claim 1 , wherein said paint spots each have a circular shape.  
     
     
         8 . The cooking appliance door as defined in  claim 1 , wherein said paint spots each have an oval shape.  
     
     
         9 . The cooking appliance door as defined in  claim 1 , wherein said paint spots each have a rectangular shape or each have a square shape.  
     
     
         10 . The cooking appliance door as defined in  claim 1 , wherein said paint spots each have a largest dimension in a range from 1 to 5 mm.  
     
     
         11 . The cooking appliance door as defined in  claim 1 , wherein said paint-free spacing between said paint spots has a size approximately equal to a largest dimension of each of said paint spots.  
     
     
         12 . The cooking appliance door as defined in  claim 1 , wherein said paint spots are printed on said inner door pane.  
     
     
         13 . The cooking appliance door as defined in  claim 1 , wherein said paint spots are printed on said inner door pane by a screen printing technique.  
     
     
         14 . A cooking appliance comprising 
 a cooking compartment with an opening for introducing cooking materials; and    a cooking appliance door for closing said opening of the cooking compartment;    wherein said cooking appliance door comprises an inner door pane of borosilicate glass and at least one paint layer applied to a surface on one side of said inner door pane, wherein said at least one paint layer comprises high-temperature-resistant non-enamel paint with an organic or inorganic binder and said at least one paint layer consists of a plurality of individual paint spots each having a predetermined maximal geometric shape, wherein said individual paint spots are arranged in a predetermined pattern with a predetermined paint-free spacing from each other on said surface on said one side of said inner door pane.    
     
     
         15 . The cooking appliance as defined in  claim 14 , wherein said shape of each of said paint spots is circular, oval, rectangular or irregular, said paint spots each have a largest dimension in a range from 1 to 5 mm and said paint-free spacing between said paint spots has a size approximately equal to said largest dimension of each of said paint spots.  
     
     
         16 . The cooking appliance as defined in  claim 14 , wherein said predetermined pattern is in the form of a grid comprising a plurality of rows of said paint spots arranged one above the other.  
     
     
         17 . The cooking appliance as defined in  claim 14 , wherein said predetermined pattern is in the form of an irregular line-shaped pattern.
