Abstract

The present invention relates to a sealing system for an oven cavity (10) of an oven, in particular of a cooking oven. The sealing system includes an outer steam-tight gasket (20) attachable or attached at a front frame (26), which encloses a cavity frame (12) of the oven cavity, which in turn encloses a front opening of said oven cavity (10). The sealing system includes an inner heat resistant gasket (18) attachable or attached at the cavity frame (12) and/or at the front frame (26), so that the inner heat resistant gasket (18) is aligned at least partially at the cavity frame (12) and at an inner panel (16) of an oven door (14) for closing the oven cavity (10) in a closed state of said oven door (14). The sealing system includes a gap sealing (19) arrangeable or arranged within a gap between the cavity frame (12) and the front frame (26), so that the gap sealing (19) encloses completely or partially the cavity frame (12). The inner heat resistant gasket (18) and the outer steam-tight gasket (20) are attachable or attached in such a way, that said inner heat resistant gasket (18) and outer steam-tight gasket (20) are aligned at the inner panel (16) of the oven door (14) at least in the closed state of said oven door (14).

         8 . The sealing system according to  claim 1 , wherein the inner heat resistant gasket is attachable or attached at the cavity frame and/or the front frame, wherein at least one contact line is formed between said inner heat resistant gasket and the inner panel of the oven door in the closed state of the oven door. 
     
     
         9 . The sealing system according to  claim 6 , wherein the inner heat resistant gasket is attachable or attached at the inner panel of the oven door or at the cavity frame, respectively, by clips, bolts, screws or the like. 
     
     
         10 . The sealing system according to  claim 1 , wherein the outer steam-tight gasket is attached or attachable at the front frame enclosing the cavity frame of the oven cavity. 
     
     
         11 . The sealing system according to  claim 1 , wherein the outer steam-tight gasket is coated by a heat resistant layer. 
     
     
         12 . A cooking oven comprising at least one sealing system according to  claim 1 , wherein:
 the oven comprises at least one oven cavity,   the oven cavity includes a cavity frame enclosing a front opening of said oven cavity,   the oven cavity includes a front frame enclosing the cavity frame of said oven cavity,   front sides of the cavity frame and the front frame extend within one plane,   the oven comprises at least one oven door for closing the front opening of said oven cavity, and   at least that portion of an inner side of the oven door arranged in front of the cavity frame and front frame in a closed state of the oven door extends within one plane.   
     
     
         13 . The oven according to  claim 12 , wherein the inner side of the oven door extends within one single plane. 
     
     
         14 . The oven according to  claim 12 , wherein the cavity frame and the front frame are thermally isolated from each other. 
     
     
         15 . A cooking oven comprising: a cavity frame enclosing a front opening of an oven cavity, a door adapted to close the front opening of the oven cavity in a closed state thereof, a front frame enclosing the cavity frame in a vicinity of said front opening, an outer steam-tight gasket clamped between the cavity frame and the front frame, said steam-tight gasket extending completely around the front opening of the oven cavity and sealing against an inner glass panel of said door in the closed state thereof, and an inner heat-resistant gasket formed separately from the outer steam-tight gasket and extending at least partially along the front opening of the oven cavity, the steam-tight gasket being adapted to provide a heat seal between the cavity frame and an inner glass panel of said door in said closed state, said heat-resistant gasket being either:
 a) fixed to said cavity frame and extends forward thereof so that in the closed state of said door the heat-resistant gasket is brought into contact with the inner glass panel along a contact line therebetween to provide said seal between the cavity frame and the inner glass panel;   b) fixed to the inner glass panel of said door and extends rearward therefrom so that in the closed state of said door the heat-resistant gasket is brought into contact with the cavity frame along a contact line therebetween to provide said seal between the cavity frame and the inner glass panel; or   c) fixed to said steam-tight gasket such that in the closed state of said door said heat-resistant gasket contacts each of the cavity frame and the glass panel of said door along respective contact lines disposed respectively therebetween, which cooperate to provide said seal between the cavity frame and the inner glass panel;   wherein the inner heat-resistant gasket thermally shields the outer steam-tight gasket in the closed state of said door when the cooking oven is in operation to cook food within the oven cavity.
