Oven door architecture and method of assembly

Abstract

Provided is an oven door architecture capable of efficient cooling and one-directional assembly. The oven door assembly comprises an outer glass pane with mounting columns adhered to it. In one embodiment, a door shield is coupled to door shield locating features of the mounting columns. A glass pack comprising two more glass panes is then coupled to the door shield. A door liner is fastened over top of the assembly. The architecture of the assembly provides for two internal chambers capable of fluid communication with one another, an air intake, and an exhaust. In another embodiment, the oven door assembly has only an outer glass pane and an interior glass pane with a main chamber between them. This main chamber is in fluid communication with an intake and an exhaust, enabling the door to cool. All embodiments are capable of assembly in one direction with substantially no lateral movement. Moreover, the embodiments are highly configurable due to shared assembly interfaces and can be used on a variety of ranges, wall ovens, and the like.

         5 . The oven door assembly of  claim 4 , wherein an unobstructed airflow channel is provided between the outer glass pane and the door liner and is configured to allow air entering the at least one intake opening to flow unobstructed to the at least one exhaust opening. 
     
     
         6 . The oven door assembly of  claim 1 , wherein the oven door assembly is adapted to be assembled substantially along a single direction. 
     
     
         7 . An oven door assembly comprising:
 an outer glass pane;   first and second mounting columns coupled to the outer glass pane, each mounting column having at least one door shield locating feature;   a door shield coupled to the first and second mounting columns via the door shield locating features, the door shield having a glass pane locating feature;   a first glass pane coupled to the door shield, the glass pane locating feature configured to restrict lateral movement of the first glass pane when coupled to the door shield; and   a door liner coupled to the door shield.   
     
     
         8 . The oven door assembly of  claim 7 , wherein the door shield includes mounting column locating features configured to mate with the door shield locating features on the first and second mounting columns. 
     
     
         9 . The oven door assembly of  claim 7 , further comprising a second glass pane and a plurality of glass pack brackets secured between the first and second glass panes. 
     
     
         10 . The oven door assembly of  claim 9 , wherein the plurality of glass pack brackets includes first and second vertical brackets and first and second horizontal brackets. 
     
     
         11 . The oven door assembly of  claim 9 , wherein the door shield includes a plurality of bracket locating features and each of the plurality of glass pack brackets includes at least one mating feature configured to mate with a corresponding bracket locating feature. 
     
     
         12 . The oven door assembly of  claim 9 , wherein the plurality of glass pack brackets are configured to restrict lateral movement of the second glass pane during assembly. 
     
     
         13 . The oven door assembly of  claim 7 , comprising a first air flow chamber formed between the door liner and the door shield and a second air flow chamber formed between the outer glass pane and the door shield, the first and second air flow chambers being in fluid communication. 
     
     
         14 . The oven door assembly of  claim 13 , wherein airflow can be diverted from the second air flow chamber into the first air flow chamber via vents provided in the door shield. 
     
     
         15 . The oven door assembly of  claim 13 , wherein air moving through the second chamber travels at a higher speed than air moving through the first chamber. 
     
     
         16 . An oven door assembly comprising:
 an outer glass pane;   a door shield coupled to the outer glass pane, the door shield comprising at least one air intake vent;   a glass pack coupled to the door shield; and   a door liner secured to the door shield;   an intake opening positioned at a lower portion of the oven door assembly;   an exhaust opening positioned at an upper portion of the oven door assembly;   a first chamber defined between the door liner and the door shield; and   a second chamber defined between the outer glass pane and the door shield,   the second chamber being in fluid communication with the first chamber; and   the intake opening and the exhaust opening being in fluid communication with the first chamber and the second chamber; wherein a volume of air entering the intake opening would be divided and travel through the first chamber and the second chamber, and exit through the exhaust opening.   
     
     
         17 . The oven door assembly of  claim 16 , wherein:
 the first chamber is smaller than the second chamber, so less than half of the volume of air entering the intake opening would travel through the first chamber; and   the remaining volume of air would travel through the second chamber.
