Door assembly and cooking device having the same

Abstract

The present disclosure discloses a door assembly and a cooking device including the door assembly. The door assembly includes a first frame, a second frame and shielding members; the second frame fits the first frame and is provided with flanges along edges thereof, the flanges are provided with notches at corners of the first frame, and the flanges shield an outer side of edges of the first frame; and the shielding members are arranged on an outer side of the flanges and detachably fit the flanges to close the notches. The second frame is formed by cutting and bending a metal plate, and there are notches at corners of the second frame formed by the cutting and bending. When the first frame fits the second frame, the first frame is spaced apart from the second frame.

What is claimed is:

         2 . The door assembly according to  claim 1 , wherein the shielding member comprises:
 a first plate-shaped portion, which abuts against an outer surface of the flange and closes the notch; and   at least one positioning portion, which is provided on the first plate-shaped portion, and which fits a positioning hole on the flange.   
     
     
         3 . The door assembly according to  claim 2 , wherein the shielding member further comprises a first clamp-fit portion, the flange is provided with a second clamp-fit portion, and the first clamp-fit portion and the second clamp-fit portion fit each other by clamping. 
     
     
         4 . The door assembly according to  claim 3 , wherein the first clamp-fit portion is an elastic clamping joint, the second clamp-fit portion is a clamping hole communicating with the notch, and the elastic clamping joint fits an inner wall of the clamping hole. 
     
     
         5 . The door assembly according to  claim 2 , wherein a side of the flange away from the second frame is provided with a folded edge penetrated by the notch; the folded edge and the second frame are both located on the same side of the flange; the second frame, the flange and the folded edge form an installation space, and the first frame is arranged in the installation space. 
     
     
         6 . The door assembly according to  claim 5 , wherein the shielding member further comprises a second plate-shaped portion connected with the first plate-shaped portion, and the second plate-shaped portion abuts against the folded edge to close at a position where the folded edge is penetrated by the notch. 
     
     
         7 . The door assembly according to  claim 6 , wherein the door assembly further comprises fasteners, the folded edges are provided with first holes, the second plate-shaped portion is provided with second holes arranged corresponding to the first holes, and the fasteners pass through the second holes to fit the first holes so that the shielding member is fixed. 
     
     
         8 . The door assembly according to  claim 7 , wherein a number of the first holes is two, two first holes are respectively arranged on both sides of the position where the folded edge is penetrated by the notch, and a number of the second holes and a number of the fasteners are each consistent with a number of the first holes; and
 the fasteners are rivets.   
     
     
         9 . The door assembly according to  claim 1 , wherein the shielding member is a high-temperature resistant alloy member; and
 the door assembly further comprises a first glass pane, which is embedded on the first frame; and   the door assembly further comprises a second glass pane, which is embedded on the second frame.   
     
     
         10 . A cooking device, comprising:
 a door assembly, comprising:   a first frame;   a second frame, which fits the first frame and which is provided with flanges along edges thereof, the flanges being provided with notches at corners of the first frame and the flanges shielding an outer side of edges of the first frame; and   shielding members, which are arranged on an outer side of the flanges and which detachably fit the flanges to close the notches; and   a cabinet, which is provided with a cooking cavity, the door assembly being pivotally arranged on the cabinet to open or close the cooking cavity.
