The overall shape of the heat shield 14 substantially conforms to the overall shape of the inner wall surface of the lining member 13, and the heat shield 14 is fitted in the recessed region 131 of the lining member 13 with a gap between the heat shield 14 and the lining member 13, thereby forming the heat insulating sandwich 16. In the assembled state, the opening of the heat shield 14 is also downward, the inner cavity of the heat shield 14 itself is a first accommodating chamber 141 for accommodating the heating unit 30, and more specifically, a second accommodating chamber 142 for accommodating the thermal circulation fan 32 is formed on the top of the first accommodating chamber 141 in a concave manner, wherein the diameter of the first accommodating chamber 141 is larger than that of the second accommodating chamber 142. That is, in a natural state, the thermal circulation fan 32 of the air supply unit is located above the heating unit 30, so that in the working process, the thermal circulation fan 32 can send the heat generated by the heating unit 30 into the inner cavity of the pot body 20 below, so that the food material in the pot body 20 is heated more uniformly, and the cooking effect is improved.

The wall of the recessed region 131 of the lining member 13 has a mounting slot 132 (see fig. 7 for details), and the outer periphery of the heat shield 14 has a flange 144 (see fig. 8 for details) extending outward and turning upward. During assembly, the turned edge 144 of the heat shield 14 can be embedded in the mounting groove 132 of the lining member 13 to limit the position of the two in the vertical direction, and then the two can be fixed by screw members.

The wall of the recessed region 131 of the lining member 13 also has an annular wall 133 extending downward to rest on the outer wall of the heat shield 14, thereby ensuring the overall strength of the lining member 12 when assembled. Moreover, the annular wall 133, the lining member 13 and the heat shield 14 together define a third housing chamber 15 for housing a cooling fan (described below).

With continued reference to fig. 4, a limiting step 143 is formed between the first accommodating chamber 141 and the second accommodating chamber 142 of the heat shield 14, the limiting step 143 is used for placing the oil filter screen 50, specifically, the area of the oil filter screen 50 is substantially consistent with the open area of the second accommodating chamber 142, and the oil filter screen can cover the second accommodating chamber 142, so that the thermal circulation fan 32 placed in the first accommodating chamber 141 is shielded at the lower part, and the contact with oil stains is reduced. The limit step portion 143 of the heat shield 14 has a screw hole 147 therein, and the oil strainer 50 is screwed into the screw hole 147 in the limit step portion 143.

The drive motor 31 is provided on the upper portion of the lining member 13, and an output shaft thereof passes through the lining member 13 and the heat shield 14 and is connected to the heat cycle fan 32. Wherein, the driving motor 31 is located at a position corresponding to the second accommodating chamber 142 in the up-down direction. In addition, a cooling fan 33 is further disposed in the third accommodating chamber 15 defined by the annular wall 133 of the lining member 13, the lining member 13 and the heat shield 14, and the cooling fan 33 is also connected to an output shaft of the driving motor 31. That is, the heat circulation fan 32 and the cooling fan 33 are driven by the same drive motor 31.

The heating unit 30 of this embodiment is a heating pipe member wound in a ring shape and fixed to the inner wall of the heat shield 14 by a connecting member.

Fig. 5 shows a cross-sectional view at B-B in fig. 3, and fig. 6 is a perspective cross-sectional view at another angle of view in fig. 5, and it can be seen that the lining member 13 further has an air inlet 134 and an air outlet 135, the air inlet 134 is communicated with the third accommodating chamber 15, specifically, the air inlet 134 is an air inlet hole 1340 (see fig. 7) distributed on the lining member 13, and preferably, the air inlet hole 1340 is distributed at a position adjacent to the driving motor 31, so as to dissipate heat of the driving motor 31. The annular wall 133 of the lining element 13 has a notch 136 communicating the third receiving chamber 15 with the air outlet 135. In the operation process of the cooling fan 33, the airflow can sequentially flow out through the air inlet 1340, the third accommodating chamber 15 and the air outlet 135, so as to dissipate heat and cool the internal corresponding components.

The wall of the second receiving chamber 142 of the heat shield 14 further has a hot air outlet 146, and the hot air outlet 146 faces the air outlet 135 of the lining member 13. The hot air heated by the heating unit 30 is blown into the inner cavity of the pot body 20 below through the thermal circulation fan 32 to heat the food material placed therein, and finally the hot air is discharged to the outside atmosphere through the hot air outlet of the heat insulation cover 14 and the air outlet 135 of the lining member 13 in sequence.
