[0038] When the box door 200 is rotated to close the opening 111A, the box door 200 drives the net rack assembly 300 to move backward, so that the abutting of the net rack assembly 300 and the abutting piece 400 is removed, the second material receiving surface 331 moves backward relative to the first material receiving surface 311 and moves to the initial position (i.e. the second material receiving surface 331 moves to the rear side of the first material receiving surface 311 and is located at the same horizontal plane with the first material receiving surface 311), and the specific arrangement is shown in FIG. 5.

[0039] It can be understood that, referring to FIG. 5, when the box door 200 is in the closed state, the first material receiving surface 311 and the second material receiving surface 331 are both retracted into the heating cavity 111.

In this regard, on the one hand, the whole grid assembly 300 moves forward with the cabinet door 200 being rotated to open, so as to facilitate the user to take the materials on the first material receiving surface 311 and the second material receiving surface 331; on the other hand, the second material receiving surface 331 moves forward relative to the first material receiving surface 311 and above the first material receiving surface 311 on the basis of moving forward with the whole grid assembly 300. Therefore, when the user takes the materials on the second material receiving surface 331 (i.e. when the user takes the materials on the rear side of the grid assembly 300), the extent to which the user reaches into the heating cavity 111 is reduced, so as to reduce the risk of the user being scalded due to accidentally touching the wall of the heating cavity 111.

[0043] When the cabinet door 200 is rotated to open the opening 111A, the cabinet door 200 drives the grid assembly 300 to move forward through the first grid 310, so that the connecting rod assembly 320 abuts against the abutting member 400, so as to make the second grid 330 swing forward relative to the first grid 310.

[0044] When the cabinet door 200 is rotated to close the opening 111A, the cabinet door 200 drives the grid assembly 300 to move backward through the first grid 310, so that the abutting of the connecting rod assembly 320 and the abutting member 400 is released, so as to make the second grid 330 swing backward relative to the first grid 310 under the action of its own gravity, and abut against the rear side of the first grid 310 again.

[0045] In some embodiments, the net rack assembly 300 comprises a first net rack 310 and a second net rack 330, the first net rack 310 is slidably arranged in the heating cavity 111, the first net rack 310 is connected with the box door 200, the second net rack 330 is slidably arranged in the first net rack 310, the second net rack 330 abuts against the first net rack 310, the first net rack 310 and the second net rack 330 are respectively provided with the first material receiving surface 311 and the second material receiving surface 331, wherein when the box door 200 is rotated to open the opening 111A, the box door 200 drives the net rack assembly 300 to move forward through the first net rack 310, so that the second net rack 330 abuts against the abutting piece 400, so that the second net rack 330 slides forward along the inclined direction relative to the first net rack 310.
