In this embodiment, the hot air mechanism 130 includes a motor 132 and a fan blade 134, the motor 132 is fixed on the body 110, the fan blade 134 is disposed on a rotating shaft of the motor 132, and the motor 132 drives the fan blade 134 to rotate after being electrified. The hot air mechanism 130 further includes a second heating element 136, where the second heating element 136 is disposed on the body 110, and the second heating element 136 heats the fan blades 134 after being electrified.

After the hot air mechanism 130 is started, the rotating high Wen Shanshe generates high-temperature air flow, and the high-temperature air flow blows to the materials contained above the bearing part 120 so as to meet the high-temperature cooking requirement or the high-temperature disinfection requirement of the materials by contacting the surfaces of the heated materials.

The rotating fan blades 134 have a faster moving speed of the outer ring portion and a slower moving speed of the inner ring portion, and the airflow flowing toward the central area of the supporting portion 120 is correspondingly slower, and the airflow flowing toward the peripheral area around the central area is quicker. In contrast, the concave part 140 corresponding to the inner ring area of the fan blade 134 and the heating mechanism 150 of the heating support part 120 are arranged to compensate the wind speed difference, so that the heating uniformity and the heating efficiency of the materials are improved.

As shown in fig. 1 and 3, in some embodiments of the present utility model, optionally, the fan blade 134 includes: a shaft 1342 connected to the motor 132, and a recess 140 disposed opposite to the shaft 1342; the first vane 1344 has one end connected to the shaft 1342 and the other end extending toward the circumference of the shaft 1342.

In this embodiment, the fan blade 134 includes a shaft 1342 and a first blade 1344, a first end of the first blade 1344 is connected to a circumferential side of the shaft 1342, and a second end of the first blade 1344 extends toward a circumferential side region of the shaft 1342. The shaft 1342 is connected to an output shaft of the motor 132, and the motor 132 drives the shaft 1342 and the first fan 134 to rotate synchronously through the output shaft, so that the rotating fan 134 fans air, thereby generating an air flow blowing toward the support 120.

Specifically, the shaft 1342 does not fan air, and the root region of the first blade 1344 moves at a slower speed, so that the flow rate of the air flow between the inner ring of the fan blade 134 and the supporter 120 is slower. The outer ends of the first blades 1344 move at a high speed, and thus have a high fanning effect on the air, so that the flow rate of the air flow between the outer ring of the blades 134 and the supporter 120 is high.

On this basis, by disposing the concave portion 140 in alignment with the shaft 1342, the heating mechanism 150 can intensively heat the concave portion 140 having a low air flow speed, so as to compensate for the difference in flow rate between the inner and outer air flows by heat concentration of the concave portion 140. And further, the structural layout of the heating assembly 100 is optimized, and the technical effects of heating uniformity and reliability of the heating assembly 100 are improved.

Wherein, in the radial direction of the shaft body 1342, the length of the first blade 1344 is longer than the length of the second blade 1346, i.e. the first blade 1344 is a long blade and the second blade 1346 is a short blade. Meanwhile, the second blade 1346 is disposed opposite the recess 140.

After the motor 132 is started, the shaft body 1342 drives the first blade 1344 and the second blade 1346 to rotate synchronously, and the rotating second blade 1346 can cooperate with the first blade 1344 to accelerate the air secondarily at the inner ring of the fan blade 134, so as to improve the flow velocity of the air flow output by the inner ring of the fan blade 134, reduce the difference of the flow velocity of the air flow between the inner ring and the outer ring of the fan blade 134, and further reduce the heating temperature difference of the hot air in the central area and the peripheral area of the bearing part 120.

Therefore, by arranging the second blades 1346, the difference between the inner wind speed and the outer wind speed above the tray can be further reduced by matching with the concave portion 140, so as to achieve the technical effects of improving the heating uniformity and the reliability of the heating assembly 100, and improving the cooking or drying effect of the materials.

The second electric heating member is disposed at the circumferential side of the fan blade 134, and the energized second electric heating member heats the fan blade 134 in the center and the surrounding air by heat radiation to output high temperature air flow.

As shown in fig. 1 and 3, in some embodiments of the present utility model, optionally, the hot air mechanism 130 further includes: the cover 138 covers the periphery of the fan blade 134 and includes a through hole.

In this embodiment, the hot air mechanism 130 further includes a housing 138, where the housing 138 is disposed on a peripheral side of the fan 134 to separate the fan 134 from the supporting portion 120. Wherein, the cover 138 is provided with a plurality of through holes, and the plurality of through holes are uniformly distributed on the cover 138 to ensure that high-temperature air flows can penetrate through the cover 138 and blow to the supporting part 120.
