ABSTRACT:
A door assembly for a cooking apparatus is provided that prevents heat generated in a cooking chamber from being released to the outside while also being as thin as possible. The door assembly may include a glass support that supports a first glass panel on a front side, and a second glass panel on a rear side. The second glass panel may be supported by a seating protrusion and catching protrusions formed on the rear side of the glass support. A door frame may be coupled to the rear side of the glass support, with a third glass panel coupled to either a front or rear side thereof. A cover frame may be coupled to the rear side of the glass support to enclose the first, second and third glass panels and the door frame.
