As the preferred scheme of the utility model, outside glass door subassembly's glass door on be equipped with the glass heat insulating membrane. The glass heat insulation film of this scheme is current product, and is similar with the reflection heat insulation film, and the totality is transparent, also has the ability of absorption and reverse radiation long wave infrared ray, sets up glass heat insulation film on outside glass door subassembly, has reduced outside glass door subassembly's temperature more.

As the utility model discloses preferred scheme, chamber door frame bottom both sides be equipped with articulated base respectively, articulated base be equipped with articulated dead lever, articulated dead lever one end articulated with articulated base, the articulated dead lever other end stretch into in the electric oven box and fixed with the electric oven box. The long end of the hinged fixing rod is fixed in the electric oven box body, and the electric oven box body can be internally provided with a corresponding guide structure, so that the electric oven is simple and convenient to install.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses in, the chamber door adopts glass door, can be to the better observation of the inside baking situation of electric oven box, overall structure is simple, excellent in use effect.

2. The utility model discloses in, the chamber door adopts four layers of glass settings, and inboard glass door subassembly, outside glass door subassembly are thermal-insulated effectual double glazing structure, have still set up the heat dissipation through-hole on the chamber door frame, and a large amount of heats are taken away in the accessible air convection for outside glass door subassembly surface temperature keeps in safe temperature range.
