Specifically, as an example, the frying plate 140 is provided with a plurality of oil leakage holes, which can filter grease and prevent grease from accumulating at the bottom of the food material, and the food material is too greasy.
Further, in order to enable the hot wind blown out from the second outlet 250 located above to be blown onto the food material, in some embodiments, as shown in fig. 4 and 12, the second outlet 250 is inclined downward, and the inclination angle α 8 of the second outlet 250 is 30 ° to 60 °.
In these embodiments, the provision of the second outlet 250 in an inclined configuration can serve to direct the airflow within the air cavity 260, such that the circularly rotating airflow in the air cavity 260 can be directed obliquely downward into the container body 110, such that the airflow can flow to the food material located on the fry vat 140 of the container body 110. Further, the inclination angle α 8 of the second air outlet 250 is defined within a range of 30 ° to 60 °, in which the hot air blown into the container body 110 via the first air outlet 240 can be made to reach the center of the food material distribution position, and the resistance of the hot air entering from the first container air inlet 1101 rising upward is overcome, so that the inside of the container body 110 is heated uniformly; specifically, if the inclination angle is too small, the wind may reach the surface of the food material in advance, may not reach the central range of the food material in the container body 110, may form a rotation inside the container body 110, and then may be thrown toward the sidewall of the container body 110, causing uneven heating, resulting in a central temperature lower than the outer periphery; if the inclination angle is too large, the wind can delay to reach the central range of the food material, and can exceed the central range of the food material in the container body 110, and then rotate in the container body 110, and further throw the food material to the side wall of the container body 110, so that uneven heating is caused, and the central temperature is lower than the periphery.
For the specific arrangement of the first outlet port 240 and the second outlet port 250, in some embodiments, as shown in fig. 12, the distance H3 between the first outlet port 240 and the second outlet port 250 in the vertical direction is 40mm to 80 mm. Within this range, the distance H3 between the first outlet 240 and the second outlet 250 is ensured to be appropriate, so that the problem that the food is too close to the first outlet and the second outlet is burnt and the like due to too close distance is avoided, and the problem that the cooking time is long and the food is difficult to cook due to too far heating efficiency is also avoided.
In some embodiments, as shown in fig. 12, the length W1 of the first air outlet 240 in the vertical direction is less than the length W2 of the second air outlet 250 in the vertical direction. Since the hot air rises upward, the second outlet 250 needs to be blown obliquely downward, the pressure required is greater, and thus the length W2 of the second outlet 250 in the vertical direction is set to be greater.
As shown in fig. 12, in some embodiments, the length W1 of the first air outlet 240 in the vertical direction is 1.5mm to 5 mm. In this range, the air output can be ensured, and the air speed through the first air outlet 240 is increased, so that the air flow can be distributed to most of the space in the container body 110, and the heating efficiency is ensured; specifically, if the length W1 of the first air outlet 240 in the vertical direction is too large, the flow rate of the wind is increased, the wind speed is reduced, and the hot wind cannot be blown to the surface of the food material; if the height is too small, the flow rate is reduced, the wind speed is increased, and the heating efficiency is low.
In some embodiments, the first container intake vent 1101 is 2mm to 7mm in length in the vertical direction. Within this range, the size of the first outlet port 240 can be better matched and slightly larger than the first outlet port 240, thereby reducing the leakage of the hot wind as much as possible.
As shown in fig. 12, in some embodiments, the length W2 of the second air outlet 250 in the vertical direction is 2mm to 6 mm. In this range, the air output can be ensured, and the air speed through the second air outlet 250 is increased, so that the air flow can be distributed to most of the space in the container body 110, and the heating efficiency is ensured; specifically, if the length W2 of the second air outlet 250 in the vertical direction is too large, the flow rate of the wind is increased, the wind speed is reduced, and the hot wind cannot be blown to the surface of the food material; if the height is too small, the flow rate is reduced, the wind speed is increased, and the heating efficiency is low.
In some embodiments, the second container intake vent 1102 has a length in the vertical direction of 2mm to 7 mm. Within this range, the size of the second outlet 250 can be better matched and slightly larger than the second outlet 250, thereby reducing the leakage of hot air as much as possible.

In some embodiments, the air outlet direction of the air supply member 310 is tangential to the inner wall of the air cavity 260. By the arrangement, the air blown out by the air supply member 310 flows more smoothly in the annular air cavity 260, and the wind resistance is reduced.
In some embodiments, as shown in fig. 24, in the horizontal cross section, the minimum distance L7 between the air supply member 310 and the annular center line of the air cavity 260 ranges from 5mm to 25 mm. Within this range, a certain safety distance can be kept between the air supply member 310 and the heating member 320, and the air supply member 310 is prevented from being too close to the heating member 320 and being damaged due to too high temperature.
