Cooking appliance having a component formed from a thin rigid sheet material

Abstract

A cooking appliance includes: at least one first component formed from a thin rigid sheet material. The at least one first component has a through-hole for receiving a screw of a screw connection between a second component and the at least one first component. The at least one first component includes at least two layers of the thin rigid sheet material in a region of the through-hole. Interengaging collars of the at least two layers of the thin rigid sheet material are formed around the through-hole.

1 . A cooking appliance, comprising:
 at least one first component comprises a thin rigid sheet material,   wherein the at least one first component has a through-hole configured to receive a screw of a screw connection between a second component and the at least one first component,   wherein the at least one first component comprises at least two layers of the thin rigid sheet material in a region of the through-hole, and   wherein interengaging collars of the at least two layers of the thin rigid sheet material are formed around the through-hole.   
     
     
         2 . The cooking appliance of  claim 1 , wherein the interengaging collars comprise a plunged hole through the at least two layers of the thin rigid sheet material. 
     
     
         3 . The cooking appliance of  claim 1 , wherein the at least two layers are formed by folding the thin rigid sheet material over itself. 
     
     
         4 . The cooking appliance of  claim 1 , wherein the at least one first component is welded to a third component. 
     
     
         5 . A method for manufacturing the cooking appliance of  claim 1 , the method comprising:
 placing the at least two layers of the thin rigid sheet material on top of each other;   forming a core hole through the at least two layers of the thin rigid sheet material; and   pushing a mandrel having a target diameter through the core hole to form the through-hole.   
     
     
         6 . The cooking appliance of  claim 1 , wherein the cooking appliance comprises an oven. 
     
     
         7 . The cooking appliance of  claim 4 , wherein the third component comprises a thin rigid sheet material.
