Cooking oven with a cooled door that permits pyrolysis

Abstract

A cooking oven includes a heatable oven chamber that can be loaded with product from the outside area through a loading port. An oven door serves to close off the loading port of the oven chamber from the outside area. An inner pane faces the oven chamber, an outer pane faces the outside area, and one or several intermediate panes are positioned between the inner pane and the outer pane. An outer cavity is between the outer pane and the neighboring intermediate pane and an inner cavity space is between the inner pane and the neighboring intermediate pane. A cooling system moves cooling air through the outer cavity while thermally insulating air can be held stationary in the inner cavity.

1 . A cooking oven, including: 
 a heatable oven chamber that can be loaded with product from an outside area through a loading port;    an oven door that serves to close off the loading port of the oven chamber from the outside area, the door including an inner pane facing the oven chamber, an outer pane facing the outside area, and at least one intermediate pane positioned between the inner pane and the outer pane, with an outer cavity provided between the outer pane and the neighboring intermediate pane and an inner cavity provided between the inner pane and the neighboring intermediate pane;    two mutually parallel support posts that extend vertically when the oven door is closed to secure the inner pane and the at least one intermediate pane together; and    a cooling system by means of which cooling air can be moved through the outer cavity while thermally insulating air can be held stationary in the inner cavity.    
   
   
       2 . An oven as set forth in  claim 1 , in which the cooling system includes air ducting that serves to guide the cooling air, primarily from an outside area that is at least at one of a location below the door and to the side of the door, into the outer cavity and through a top portion of the door to the outside area, and to entrap thermally insulating air in the inner cavity for at least one of a location at the top portion of the door and the sides of the door.  
   
   
       3 . A cooking oven, including: 
 a heatable oven chamber that can be loaded with product from an outside area through a loading port;    an oven door that serves to close off the loading port of the oven chamber from the outside area, the door including an inner pane facing the oven chamber, an outer pane facing the outside area, and at least one intermediate pane positioned between the inner pane and the outer pane, with an outer cavity provided between the outer pane and the neighboring intermediate pane and an inner cavity provided between the inner pane and the neighboring intermediate pane; and    a cooling system by means of which cooling air can be moved through the outer cavity while thermally insulating air can be held stationary in the inner cavity,    in which the cooling system includes air ducting that serves to guide the cooling air, primarily from an outside area that is at least at one of a location below the door and to the side of the door, into the outer cavity and through a top portion of the door to the outside area, and to entrap thermally insulating air in the inner cavity for at least one of a location at the top portion of the door and the sides of the door, and    in which the air ducting includes two mutually parallel longitudinal supports which laterally separate the inner cavity from the outer cavity.    
   
   
       4 . An oven as set forth in  claim 2 , in which the air ducting includes a transverse support which from the top separates the inner cavity from the outer cavity.  
   
   
       5 . An oven as set forth in  claim 4 , in which the transverse support has a U-shaped cross section with a longer outer leg that is attached to an inside surface of the outer pane and with a shorter inner leg that bounds a gap with the inner surface of the outer pane and that delimits a top of the inner cavity.  
   
   
       6 . An oven as set forth in  claim 5 , in which a cross member of the transverse support connects the legs the cross member is provided with air exit openings, and at least some of the air exit openings are oriented toward the oven.  
   
   
       7 . An oven as set forth in  claim 6 , in which the transverse support includes a channel that is aligned with the outer cavity and connects the outer cavity to the air exit openings.  
   
   
       8 . An oven as set forth in  claim 4 , in which the transverse support is positioned on top of longitudinal supports.  
   
   
       9 . An oven as set forth in  claim 4 , in which the transverse support and longitudinal supports have interconnection portions that provide for detachability of the interconnection portions.  
   
   
       10 . An oven as set forth in  claim 9 , including cement to affix the transverse support and the longitudinal supports to the outer pane.  
   
   
       11 . An oven as set forth in  claim 10 , wherein at least one of the longitudinal and the transverse supports has a U-shaped cross section with a longer outer leg that is cemented to the outer pane.  
   
   
       12 . An oven as set forth in  claim 11 , in which the cement is provided as a series of spots.  
   
   
       13 . An oven as set forth in  claim 2 , in which the air ducting includes a connection between the bottom end of the outer cavity and the outside area.  
   
   
       14 . An oven as set forth in  claim 1 , in which the cooling system includes at least one cooling blower that draws the cooling air primarily from the outside area through the outer cavity and to blow it back into the outside area.  
   
   
       15 . An oven as set forth in  claim 14 , in which the blower is connected respectively to an intake channel that leads to air exit openings of the oven door and to an exhaust channel that leads to the outside area through an opening above the oven door.  
   
   
       16 . An oven as set forth in  claim 1 , further comprising a transverse support detachably connected to the support posts.
