Under the action of the fan 40, the oil smoke enters the cavity through the suction port 31, the oil smoke in the cavity directly enters the first air channel and the second air channel through two ends of the opening 32 under the action of air flow, and no object is used for blocking the oil smoke to flow in the process, so that the energy loss in the oil smoke flowing process is effectively reduced.

Further, the suction unit 30 of this embodiment connects the bottom of front plate 35 with the bottom of backplate 33, and the top of front plate 35 is connected with the bottom plate 12 of casing 10, thereby make front plate 35 set up towards the slope of cooking utensils 200, make the induction port 31 be close to cooking utensils 200 setting more, reduced the oil smoke and got into the route in the suction unit 30, the oil smoke that produces when cooking utensils 200 during operation promptly can be more quick gets into in the suction unit 30, thereby guarantee before the oil smoke diffusion with the oil smoke all inhale in the cavity of suction unit 30, reach better oil smoke absorption effect.

As shown in fig. 4, the cooking apparatus 100 of the present embodiment further includes a rotating unit 50. The rotating unit 50 includes a rotating shaft 51. Wherein, the rotating shaft 51 is provided at the connection position of the back plate 33 and the back plate 13 of the housing 10, and the back plate 33 is rotatably connected to the housing 10 through the rotating shaft 51. By arranging the rotating shaft 51, the air suction unit 30 is rotatably arranged at the bottom of the heating cavity 20, so that when oil smoke needs to be exhausted, the air suction unit 30 is rotated to the position shown in fig. 1, the back plate 33 of the air suction unit 30 is flush or basically flush with the back plate 13 of the housing 10, and the suction port 31 faces and is close to the cooker 200, thereby effectively absorbing the oil smoke. When the oil smoke is not to be exhausted, the suction unit 30 is rotated in the black arrow direction of fig. 4 to make the front plate 35 approach toward the bottom plate 12 of the housing 10 and finally make the back plate 33 flush with the bottom plate 12, thereby increasing the overall height of the suction unit 30 and improving the appearance of the cooking apparatus 100.

As shown in fig. 4, the rotating unit 50 of the present embodiment further includes a telescopic rod 52, one end of the telescopic rod 52 is connected to the housing 10, and the other end of the telescopic rod 52 is connected to the back plate 33. The automatic rotation of the air suction unit 30 is realized by arranging the telescopic rod 52, and the air suction unit 30 can be controlled to rotate according to a preset angle by further arranging the length of the telescopic rod 52, so that the arrangement angle of the suction inlet 31 relative to the stove 200 after rotation at every time is ensured, and the oil fume exhaust effect is ensured. Specifically, the telescopic rod 52 of the present embodiment is an electrically controlled hydraulic rod, and can rotate the air suction unit 30 at any time as required.

As shown in fig. 5, since the first air duct and the second air duct are respectively disposed at two sides of the heating cavity 20 according to the present embodiment, the fan 40 disposed above the heating cavity 20 needs to suck air in the first air duct and the second air duct at the same time. In this embodiment, the number of the blower 40 is one, the blower 40 includes a motor 41 and two volutes 42, output shafts are disposed at two ends of the motor 41, the two volutes 42 are respectively disposed at two ends of the motor 41, and a wind wheel 43 is disposed inside any one of the volutes 42. The wind wheel 43 is connected with the output shaft, the air inlet ends 44 of the two volutes 42 are respectively communicated with the first air channel and the second air channel, and the air outlet ends 45 of the two volutes 44 are respectively communicated with the outside of the shell 10. The rotation of the motor 41 drives the wind wheels 43 in the two volutes 42 to rotate, and the rotation of the wind wheels 43 makes the oil smoke enter the volutes 42 at the two ends of the motor 41 along the first air channel and the second air channel respectively, and finally is discharged to the outside of the housing 10 through the air outlet end 45, thereby completing the process of sucking and discharging the oil smoke.

Under the action of the fan 40, the oil smoke generated by the cooker 200 can enter the inside of the air suction unit 30 through the air suction port 31 in the direction shown by the arrow in fig. 7, and is finally discharged to the outside of the housing 10.

Further, in order to reduce the space occupancy of the cooking apparatus 100 and improve the oil smoke suction effect, the cooking apparatus 100 of this embodiment further includes a lifting unit (the lifting unit is disposed inside the housing, not shown in the drawings). The lifting unit is connected with the air suction unit 30, and the lifting unit is used for controlling the air suction unit 30 to move towards or away from the cooker 200, so that when oil smoke generated by the cooker 200 needs to be sucked, the air suction unit 30 is lowered to the position shown in fig. 7 through the lifting unit, the suction port 31 is arranged close to the cooker 200, and the oil smoke is effectively sucked. When the oil smoke does not need to be sucked, the air suction unit 30 is lifted by the lifting unit, so that the end plate at the bottom of the air suction unit 30 is flush with the bottom plate 12 of the housing 10, thereby reducing the space occupancy rate of the cooking apparatus 100 and improving the overall appearance effect of the cooking apparatus 100. Since the lifting unit is a technical means well known to those skilled in the art, it will not be described herein. Specifically, a hydraulic driving structure may be adopted, such that an output end of the hydraulic driving structure is connected to the end plate, and a fixed end of the hydraulic driving structure is connected to the internal structure of the housing 10, thereby completing the lifting process of the air suction unit 30.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
