[0036] Please refer to Figures 1 to 3 , in an embodiment of the present invention, an air fryer oven with a convective heat transfer structure includes a box body 1, a fryer 2, a lifting and shaking component 3, and a convective heat transfer component. Among them, multiple fryers 2 are arranged in a circumferential arrangement in the box body 1 in a manner that can be offset and shaken by the lifting and shaking component 3;

[0037] The convective heat transfer component includes a convective fan blade, a heating pipe 9, and a second deflector plate 14. Among them, the two second deflector plates 14 are symmetrically arranged in the box body 1, so as to sequentially divide the box body 1 from left to right into a first gas rising space, a heating space, and a second gas rising space. The convective fan blade can suck the air in the heating space, send it to the first gas rising space and the second gas rising space after being heated by the heating pipe 9, and then converge back to the heating space. The convective heat transfer component further includes a partition plate 4, and the partition plate 4 is horizontally arranged at the bottom of the box body 1. Among them, there is a certain gap between the bottom of the deflector plate 14 and the partition plate 4, and there is a certain gap between the top of the deflector plate 14 and the inner top wall of the box body 1 to facilitate the internal air circulation;

[0038] The middle part of the partition plate 4 is recessed upward to form a receiving groove, and the receiving groove can accommodate part of the convective fan blade;

[0039] A plurality of air suction holes 7 are opened on the bottom of the receiving groove, and the range occupied by the plurality of air suction holes 7 matches the range occupied by the convective fan blade;

[0040] A plurality of air outlet holes 8 corresponding to the positions of the first gas rising space and the second gas rising space are symmetrically opened on both sides of the partition plate 4. In a specific implementation, when the convective fan blade rotates, it can suck the air in the heating space, send it to the position of the air outlet hole 8 after being heated by the heating pipe 9, and send it to the first gas rising space and the second gas rising space through the air outlet hole 8.

[0041] As a preferred embodiment, a convective motor 5 capable of driving the convective fan blade to rotate is fixed in the gas passage formed by the partition plate 4 and the bottom of the box body 1, and a heat insulation sleeve 6 is fixed outside the convective motor 5.

[0042] In this embodiment, a gas supplementing component is further included. The gas supplementing component includes a gas supplementing motor 10 and a retaining plate 12. The retaining plate 12 is in an inverted ︺ shape, and its front and rear end faces are respectively connected to the front and rear faces of the box body 1, so as to form a retaining channel between the retaining plate 12 and the box body 1;

[0043] The retaining plate 12 on the left side is arranged above the partition plate 4 and has a certain distance from the partition plate 4. A gas supplementing fan blade is placed between the retaining plate 12 on the left side and the box body 1. The gas supplementing fan blade is rotatably arranged on the box body 1 by a shaft body, and the gas supplementing fan blade is driven to rotate by a gas supplementing motor fixed on the box body 1.
