Thus, the first partition plate 93 can prevent cold air entering from the front side air inlet and hot air discharged from the front side air outlet 94 from mutually mixing, and prevent hot air discharged from the front side air outlet 94 from directly entering the front side air inlet and then entering the box body 10, so as to play a good buffering role, namely, the hot air is firstly radiated between the hot air and the outside air after being discharged from the front side air outlet 94, and then enters the box body 10 after passing through the front side air inlet; in addition, the hot wind discharged from the front side wind outlet 94 may be reflected toward the front upper side of the case 10 by the first partition 93, and thus may not be easily sucked by the front side wind inlet.

Further, referring to fig. 3 to 6, a lateral surrounding edge 95 is disposed on a side of the top wall of the cooking cavity 12, which is far away from the door body 20, the lateral surrounding edge 95 is attached to the top cover plate 115, and two ends of the lateral surrounding edge 95 are disposed at an interval with the first side cover plate 112 and the second side cover plate 113, respectively. Thus, the transverse surrounding edge 95 separates the hot air assembly 50 from the variable frequency power supply 43 and the magnetron 41, and heat generated by the hot air assembly 50 can be prevented from jumping to the variable frequency power supply 43 and the magnetron 41 behind the transverse surrounding edge 95, so that normal operation of the variable frequency power supply 43 and the magnetron 41 is affected.

Further, referring to fig. 3 to 6, the lateral surrounding edge 95 includes a main surrounding edge 951 and an arc surrounding edge 952 connected to one end of the main surrounding edge 951, and the arc surrounding edge 952 is used for guiding wind to the first partition area.

In this way, a part of the wind discharged from the second fan 44 flows along the lateral surrounding edge 95 and enters the first spaced area, and is then discharged from the front side outlet hole 61 of the front plate 60; another part of the wind discharged from the second fan 44 enters the top of the cooking chamber 12 through the ventilation gap 97, then flows through the hot wind assembly 50 and enters the first gap area, and is also discharged out of the front side air outlet 61 of the front plate 60.

Further, referring to fig. 8 to 11, the drawer type microwave oven further includes a side heat insulation plate 46 disposed at the second interval region and a bottom heat insulation plate 47 disposed at the fourth interval region. The side heat insulation plates 46 are positioned between the side walls of the cooking cavity 12 and the second slide rails 32, and the bottom of the side heat insulation plates 46 is connected with the bottom heat insulation plate 47. In this way, the side heat insulation plates 46 and the bottom heat insulation plate 47 can prevent the heat on the cooking cavity 12 from being transferred outwards to some extent, so that the temperatures of the second slide rail 32 and the driving motor 33 are not too high.

Further, the front end of the fixed rail 321 of the second slide rail 32 is connected to the front plate 60, and the rear end of the fixed rail 321 of the second slide rail 32 is fixedly connected to the side edge plate 123 of the cooking cavity 12.

Further, referring to fig. 8 to 11, an upper edge plate 124 extends from the top wall of the cooking cavity 12 towards the second side cover plate 113, an upper bent edge 461 connected to the upper edge plate 124 is disposed at the top of the side heat insulation plate 46, and a lower bent edge 462 connected to the bottom heat insulation plate 47 is disposed at the bottom of the side heat insulation plate 46. The side of the side heat insulation plate 46 is provided with a pressing edge 463 which is pressed against the side wall of the cooking cavity 12. In this way, the side heat insulation plate 46 can be stably installed on the wall of the cooking cavity 12, thereby being advantageous to ensure the stability of the driving motor 33. In addition, the pressing edge 463 can form a space between the side heat insulation plate 46 and the cavity wall of the cooking cavity 12, and can prevent heat on the cavity wall of the cooking cavity 12 from being conducted to the side heat insulation plate 46.

Further, referring to fig. 8 to 11, the drawer type microwave oven further includes a mounting bracket 98, and the connecting portion 34 is connected to a bottom side of the fixed rail 321 of the second slide rail 32. The driving motor 33 is installed on the mounting bracket 98, and the mounting bracket 98 is connected to the lower bending edge 462 and the connecting portion 34 respectively. Specifically, the mounting surface of the connecting portion 34 for connecting with the mounting bracket 98 and the mounting surface of the lower bent edge 462 for connecting with the mounting bracket 98 are flush with each other and on the same plane, so that the mounting bracket 98 can be mounted more stably.

Further, referring to fig. 8 to 11, the connecting portion 34 includes a first connecting plate 341 and a second connecting plate 342. The first connecting plate 341 is connected to the fixed rail 321 of the second slide rail 32, and the second connecting plate 342 is connected to the first connecting plate 341. The first connection plate 341 abuts against the side heat insulation plate 46 or is disposed adjacent to the side heat insulation plate 46. Thus, the driving motor 33 can be stably installed on the one hand, and the first connection plate 341 can be prevented from being bent on the other hand. In addition, the driving motor 33 is located just at a position where the second and fourth spaced areas meet. The close proximity is that there is a distance between the first connection plate 341 and the side heat insulation plate 46, and the distance is small enough, for example, 1mm to 5mm, and the specific size of the distance may be set according to the actual situation, which is not described in detail.

In order to avoid the heat on the wall of the cooking cavity 12 being conducted to the first sliding rail 31 and causing the temperature of the first sliding rail 31 to be too high, the drawer-type microwave oven also comprises a side heat insulation plate 46 disposed at the first interval region. The side heat insulation plates 46 of the first interval region are positioned between the side wall of the cooking cavity 12 and the first slide rail 31, and the bottom of the side heat insulation plates 46 of the first interval region is connected with the bottom heat insulation plate 47. In this way, the side and bottom heat insulation panels 46 and 47 can prevent heat on the cooking cavity 12 from transferring outwards to some extent, so that the temperature of the first sliding rail 31 is not too high.
