The two oil fume passages 32 are respectively located on the opposite outer sides of the cavity component 21. The number of the smoke inlets 111 is two. The two smoke inlets 111 are arranged at intervals in the left-right direction, and the two smoke inlets are respectively connected to the two oil fume passages to correspond to the use of a double burner.

[0033] Reference Figures 1-5 Referring to

[0034] Reference Figures 5-6 , the housing assembly 11 includes a U-shaped smoke collecting plate 111, two smoke guiding plates 112, a front smoke collecting plate 113 and a rear smoke collecting plate 114. The U-shaped smoke collecting plate 111 is composed of a smoke collecting bottom plate and two smoke collecting side plates. Two smoke suction ports 1111 are arranged at intervals in the left-right direction on the smoke collecting bottom plate. The two smoke guiding plates 112 are respectively connected to the upper ends of the two smoke collecting side plates, and the two smoke guiding plates 112 jointly enclose an "eight" shape. The front smoke collecting plate 113 is arranged above the U-shaped smoke collecting plate 111 and is respectively connected to the two smoke guiding plates 112 and the upper end of the U-shaped smoke collecting plate 111. An air inlet hole group for cold air to pass through is provided at the lower end of the front smoke collecting plate 113, and the air inlet hole group is composed of a plurality of air inlet holes 1131 arranged at intervals. The rear smoke collecting plate 114 is arranged behind the U-shaped smoke collecting plate 111, and the upper and lower ends of the rear smoke collecting plate 114 are respectively connected to the U-shaped smoke collecting plate 111 and the two smoke guiding plates 112.

[0035] The housing assembly 11 further includes a seal 115. The seal 115 can be sound-absorbing cotton, sponge, oil-absorbing cotton or sealing ring, and is fixedly installed on the inner surface of the rear smoke collecting plate 114. A positioning groove 1151 is provided at the position of the seal 115 corresponding to the cavity assembly 21, and the rear end of the cavity assembly 21 is inserted into the positioning groove 1151, see Figures 3-4 , so that the rear end of the cavity assembly 21 can be quickly pre-positioned and protected by the seal 115, ensuring that the rear end of the cavity assembly 21 is not interfered by oil fume or oil stain.

[0036] Reference Figures 2-8 , the heat insulation assembly includes a heat insulation plate 131. The heat insulation plate 131 is arranged between the blower assembly 12 and the top of the cavity assembly 21, and the front and rear ends of the heat insulation plate 131 are respectively abutted against the front and back of the housing assembly 11. A receiving cavity with a downward opening is provided on the heat insulation plate 131, and the receiving cavity and the top of the cavity assembly 21 jointly enclose an installation space 31. In this embodiment, the top of the heat insulation plate 131 includes a front plane 1311, a transition connection surface 1312 and a rear plane 1313 connected in sequence. The rear plane 1313 is higher than the front plane 1311, so that the installation space 31 is arranged with a lower front end and a higher rear end. In this way, while facilitating the arrangement of the microwave assembly 23, it effectively reduces the influence of the setting of the microwave assembly 23 on the placement space of the blower assembly. The blower assembly 12 is arranged in front of the rear plane 1313, and its bottom is abutted against or in clearance fit with the front plane 1311, so that the blower assembly 12 and the heat insulation assembly 13 are arranged in a layered and offset manner, reasonably distributing the space, reducing the overall height of the machine. In addition, it ensures a larger placement space for the blower assembly, facilitating the installation of a blower assembly with a larger size or stronger wind force in the housing assembly 11, and effectively ensuring the smoking effect of the equipment for stir-frying.

[0037] In this embodiment, a clearance portion 121 is recessed at a position on the back surface of the fan assembly 12 corresponding to the transition connection surface 1312, and the height of the clearance portion 121 is less than the height of the transition connection surface 1312. A profiling portion (not shown in the figure) is provided on the transition connection surface 1312, and the profiling portion is inserted into the clearance portion 121. Refer to Figure 2 , in this embodiment, the profiling portion is profiled according to the height of the microwave assembly 23 to better meet the installation of the microwave assembly 23. It can be seen that by designing a local avoidance at the lower end of the back surface of the fan assembly 12, the installation of the heat insulation assembly 13 and the microwave assembly 23 can be better satisfied, and at the same time, the influence on the air volume performance is ensured to be small.

[0038] Specifically, the profiling portion includes at least one layer of steps 1302, and the steps 1302 are profiled according to the height of the microwave assembly 23, that is, profiled according to the height of at least one of the waveguide 231, the magnetron 232, and the motor 233. In this embodiment, the profiling portion includes one layer of steps 1302, and this layer of steps 1302 is profiled according to the height of the waveguide 231 in the microwave assembly 23. The height of the clearance portion 121 is 53 ± 3 mm, and the depth is 43 ± 3 mm. In this embodiment, the clearance portion 121 is arranged with a larger lower end and a smaller upper end. A vertical surface and an inclined surface are formed on the surface of the clearance portion 121 facing the transition connection surface 1312. The distance H1 between the vertical surface and the back surface of the fan assembly 12 is 43 ± 3 mm, and the height H2 of the vertical surface is 33 ± 3 mm. The lower end of the inclined surface is fixedly connected to the upper end of the vertical surface, and the inclined surface is inclined downward and forward, and the inclination angle is 25 ± 5°. In this way, while the clearance portion 121 meets the avoidance requirements, it can play a guiding role in the airflow or fluid, which is beneficial to reducing the airflow noise.

[0039] Refer to Figures 2-8 , since the rear plane 1313 is higher than the front plane 1311, the installation space 31 is arranged with a lower front end and a higher rear end. In this embodiment, the microwave assembly 23 includes a waveguide 231, a magnetron 232, and a motor 233. The waveguide 231 is horizontally arranged at the top of the cavity assembly 21 in the front-rear direction. A waveguide port (not shown in the figure) is provided at the front end of the waveguide 231. The magnetron 232 is arranged in the rear end of the installation space 31 and is connected to the rear end of the waveguide. At this time, the magnetron 232 is located behind the lower end of the fan assembly 12, and the two form a staggered arrangement. Refer to Figure 2。The motor 233 is arranged inside the front end of the installation space 31 and is located between the front end of the waveguide and the top of the heat insulation component 13. The output end of the motor 233 is arranged in the waveguide opening. At this time, the motor is directly below the fan assembly. Thus, by installing the motor 233 and the magnetron 232 at the front and rear ends of the installation space 31 respectively, and arranging the magnetron 232 behind the lower end of the fan assembly 12, the magnetron 232 and the fan assembly 12 are arranged in a staggered and layered manner, rationally distributing the space, ensuring that the magnetron 232 will not affect the placement space of the fan assembly 12, and thus facilitating the reduction of the overall height of the equipment.

[0040] In this embodiment, the waveguide opening of the waveguide 231 is arranged directly opposite the exact middle of the top of the cavity assembly 21. Refer to Figure 2 , to ensure that higher microwave energy efficiency can be obtained. The waveguide 231 includes a vertical section 2311 and a horizontal section 2312 connected in an "L" shape. The vertical section 2311 is arranged between the magnetron 232 and the motor 233 and is connected to the magnetron 232. In this embodiment, the vertical section 2311 is arranged corresponding to the profiling part on the heat insulation component 13 to meet the requirement of the horizontal arrangement of the microwave component 23 in the front-rear direction, ensure the efficiency of the microwave, and reduce the influence of the microwave component on the placement space of the fan assembly 12. The horizontal section 2312 is horizontally arranged in front of the vertical section and is located between the top of the heat insulation component 13 and the top of the cavity assembly 21. The motor 233 is arranged on the top of the horizontal section.

[0041] Refer to Figures 1-9 , the microwave module 2 further includes a heat dissipation component 24. The heat dissipation component 24 is arranged in the installation space 31 and is provided with a cold air outlet. The air outlet direction of the cold air outlet faces the microwave component 23. In this embodiment, the air outlet direction of the cold air outlet faces the magnetron 232 to dissipate heat from the magnetron 232. At the position on the front face of the outer shell assembly 11 corresponding to the installation space 31, there is an air inlet hole group, which is composed of a plurality of air inlet holes 1131 arranged at intervals. The installation space 31 is connected to the outside atmosphere of the outer shell assembly 11 through the air inlet hole group, so that external cold air can flow into the installation space 31 through the air inlet hole group. On the side wall of the heat insulation component 13, there is a heat dissipation hole group, which is composed of a plurality of heat dissipation holes 1301 arranged at intervals. The installation space 31 is connected to the oil fume channel 32 through the heat dissipation hole group, so that the heat generated by the operation of the microwave component 23 can flow into the oil fume channel 31 through the heat dissipation hole group and then be taken away by the fan assembly 12.

[0042] Specifically, the front and rear ends of the heat insulation component 13 are respectively abutted against the front face and the back face of the outer shell assembly 11. At the position on the front face of the heat insulation board 131 of the heat insulation component 13 corresponding to the air inlet hole group, there is a ventilation opening 1303. The air inlet hole group is connected to the inside of the installation space 31 through the ventilation opening 1303.

[0043] Refer toFigures 1-9 Moreover, the microwave module 2 further includes a heating component 25 and a hot air component 26. The heating component 25 is disposed at the bottom of the cavity component 21 for heating the interior of the cavity component 21. The hot air component 26 is disposed on the outer sidewall of the cavity component 21, and the hot air outlet of the hot air component 26 is communicated with the interior of the cavity component 21. In addition, the microwave module 2 further includes a heat preservation component 27. The heat preservation component 27 is sleeved outside the cavity component 21 and is located below the heat insulation component 13. The heat insulation component 13 is hermetically connected to the top of the heat preservation component 27, and an installation space 31 is formed between the top of the heat preservation component 27 and the heat insulation component 13. The heating component 25 is disposed between the bottom of the cavity component 21 and the bottom of the heat preservation component 27.

[0044] The above are only some embodiments of the present invention.
