Door of electric oven

Abstract

Disclosed herein is a door of an electric oven, which has an improved configuration to prevent the escape of heat from a cooking compartment to the outside during cooking or self-cleaning of the cooking compartment. The door, which serves to selectively open or close a cooking compartment of an electric oven, includes a front glass installed to a front surface, a rear glass installed behind the front glass, and a porous plate interposed between the front glass and the rear glass. The porous plate serves to prevent the escape of heat from the cooking compartment to the outside and includes a plurality of view holes to enable observation of the cooking compartment from the outside.

         2 . The door according to  claim 1 , wherein the rear glass includes a first rear glass installed adjacent to the porous plate and a second rear glass installed behind the first rear glass. 
     
     
         3 . The door according to  claim 2 , wherein the second rear glass is provided with a heat-reflective coating surface to reflect heat so as to prevent the escape of the heat from the cooking compartment to the outside. 
     
     
         4 . The door according to  claim 3 , wherein the porous plate is installed between the front glass and the first rear glass. 
     
     
         5 . The door according to  claim 3 , wherein the porous plate is installed between the front glass and the first rear glass so as to come into close contact with the first rear glass. 
     
     
         6 . The door according to  claim 3 , wherein the porous plate is installed between the first rear glass and the second rear glass. 
     
     
         7 . The door according to  claim 1 , wherein the porous plate includes a body having a plurality of view holes, and extensions protruding from left and right sides of the body toward the rear glass. 
     
     
         8 . The door according to  claim 7 , wherein the body of the porous plate includes a view portion provided with the plurality of view holes and a shield portion provided above the view portion. 
     
     
         9 . The door according to  claim 8 , wherein all surfaces of the shield portion of the porous plate are hermetically sealed to prevent the escape of heat from the cooking compartment to the outside through a door grill. 
     
     
         10 . The door according to  claim 8 , wherein the plurality of view holes of the porous plate has a circular form. 
     
     
         11 . The door according to  claim 7 , wherein the body of the porous plate and the extensions protruding from the body define an air path therebetween, and air passes through the air path from the bottom to the top of the porous plate. 
     
     
         12 . A door of an electric oven to selectively open or close a cooking compartment, comprising:
 a front glass installed to a front surface;   a rear glass including a first rear glass and a second rear glass sequentially arranged behind the front glass; and   a porous plate interposed between the front glass and the rear glass, the porous plate including a body provided with a plurality of view holes and extensions protruding from left and right sides of the body toward the rear glass,   wherein the body of the porous plate and the extensions protruding from the body define an air path therebetween, and air passes through the air path from the bottom to the top of the porous plate.   
     
     
         13 . The door according to  claim 12 , wherein the second rear glass is provided with a heat-reflective coating surface to reflect heat so as to prevent the escape of the heat from the cooking compartment to the outside. 
     
     
         14 . The door according to  claim 12 , wherein the porous plate is installed between the front glass and the first rear glass. 
     
     
         15 . The door according to  claim 12 , wherein the porous plate is installed between the first rear glass and the second rear glass. 
     
     
         16 . The door according to  claim 12 , wherein the body of the porous plate includes a view portion provided with the plurality of view holes and a shield portion provided above the view portion. 
     
     
         17 . The door according to  claim 16 , wherein all surfaces of the shield portion of the porous plate are hermetically sealed to prevent the escape of heat from the cooking compartment to the outside through a door grill. 
     
     
         18 . The door according to  claim 16 , wherein the plurality of view holes of the porous plate has a circular form. A door of an electric oven to selectively open or close a cooking compartment, the door comprising:
 a porous plate interposed between a front glass and a rear glass,   wherein the porous plate serves to prevent the escape of heat from the cooking compartment to the outside and includes a plurality of view holes to enable observation of the cooking compartment from the outside,   wherein the rear glass includes a first rear glass and a second rear glass installed behind the front glass, and   wherein the porous plate is installed between the front glass and the first rear glass so as to come into close contact with the first rear glass.
