[0006] An inner shell is arranged in the outer shell, the front end of the inner shell is open, and an air-cooling interlayer is formed between the outer shell and the inner shell; after the pot body is inserted from the front end opening of the inner shell, the upper vent is communicated with the upper side of the air-cooling interlayer, and the lower vent is communicated with the lower side of the air-cooling interlayer;

[0007] The inner shell is provided with a partition, thereby dividing the inner shell into a front cavity and a rear cavity, and there is a gap between the partition and the upper panel of the inner shell; the pot body is inserted into the front cavity, and the lower part of the rear cavity is provided with a centrifugal fan blade, and the centrifugal fan blade, the rear cavity and the upper end space of the front cavity form a centrifugal fan, and the upper end space of the front cavity is provided with an air inlet inclined from top to bottom to front; the lower bend of the rear cavity is provided with an inner cold air inlet, and the lower bend of the outer shell is provided with an outer cold air inlet corresponding to the inner cold air inlet; the lower part of the pot body and the lower part of the partition are provided with a hot air outlet corresponding to the centrifugal fan blade;

[0012] Furthermore, an air guide plate folded forward is provided at the upper end of the partition.

[0013] When the utility model is in use, heat is generated by the electric heating body, and after the centrifugal fan blades rotate, the centrifugal fan starts to work. According to the general principle of the centrifugal fan, the hot air is blown from the gap between the partition and the upper panel of the inner shell to the upper end space of the front cavity, and blown into the pot body under the guidance of the air guide plate. At the same time, due to the rotation of the centrifugal fan blades, the external cold air is sucked from the external cold air inlet and the internal cold air inlet, and a negative pressure area is formed at the rear of the air-cooled interlayer, so that the air in the cavity of the pot panel also flows toward the air-cooled interlayer through the upper vent and the lower vent, respectively, so as to form an air-cooling effect in the entire air-cooled interlayer, and finally the cold air flows out from the cold air outlet. The hot air blown into the pot body enters the rear cavity from the hot air outlet, and finally mixes with part of the cold air under the action of the centrifugal fan and flows out through the mixed air outlet channel and the mixed air outlet.

[0014] The beneficial effects of the utility model are: providing a rear-heat-conducting air fryer with a brand-new structure, adopting a centrifugal fan and a rear-placed electric heating body, achieving the effect of hot air blowing into the pot body and air cooling, and having a simple structure.
