The lower bracket 24 is formed into a U shape and is arranged at the lower part of the inner wall of the door glass 1 corresponding to the inverted U-shaped structure formed by the upper left corner bracket 21, the upper bracket 23, and the upper right corner bracket 22, and there is a spacing between the two U-shaped structures. The left side bracket 25 is vertically connected between the second support plate 212 and one end of the corresponding lower bracket 24, and the right side bracket 26 is vertically connected between the fourth support plate 222 and the other end of the corresponding lower bracket 24. The cross-sections of the left side bracket 25 and the right side bracket 26 are both L-shaped and are arranged relatively on the door glass 1, so that the upper left corner bracket 21, the upper right corner bracket 22, the upper bracket 23, the lower bracket 24, the left side bracket 25 and the right side bracket 26 together enclose a circular structure. In the above structure, the upper left corner bracket 21 and the upper right corner bracket 22 are fixed to the door glass 1 by gluing and screwing and welded to the upper bracket 23, the left side bracket 25 and the right side bracket 26 are respectively arranged on the door glass 1 by gluing, the door inner panel 3 is fixedly connected to the left side bracket 25 and the right side bracket 26 by screws, the upper bracket 23 and the lower bracket 24 are fixed to the door glass 1 by gluing and screwing, the rear end of the door body latch 6 is fixed to the upper left corner bracket 21 / upper right corner bracket 22 by welding, the connection between the door inner glass 5 and the door inner panel 3 is glued to avoid air leakage and water leakage, the door inner panel 3 and the above components are made of stainless steel, which is not easy to be deformed by heat to avoid microwave leakage. The lower left corner bracket 27 is arranged at the lower left corner of the inner wall of the door body glass 1 and has a first support plate 271 capable of supporting the lower left bend of the lower bracket 24. The lower right corner bracket 28 is arranged at the lower right corner of the inner wall of the door body glass 1 and has a second support plate 281 capable of supporting the lower right bend of the lower bracket 24. The lower left corner bracket 27 and the lower right corner bracket 28 are respectively welded to the door inner panel 3. This structure makes the entire door inner panel 3 and the bracket assembly 2 form a whole, avoiding air leakage, water leakage, and microwave leakage.

[0036] The inner wall surface of the door body glass 1 is connected with a hinge 7 that can be connected to the cooking box. The hinge 7 is arranged on the outer side of the lower left corner bracket 27 and the lower right corner bracket 28.

[0037] The bottom of the lower bracket 24 of this embodiment is provided with a connecting plate 241 extending along the length direction of the door glass 1, and the bottom of the connecting plate 241 is provided with a guiding silicone strip 29 that can pour condensed water into the cooking box when the door is closed relative to the cooking box. The guiding silicone strip 29 includes a horizontally arranged connecting piece 291 and a guiding piece 292 extending backward and downward from the rear edge of the connecting piece 291, and the rear side surface of the guiding piece 292 is formed as an arc surface arched forward.
