Optionally, the plurality of air guiding protrusions 530 may be spirally disposed around the central axis of the heating cavity 110, in other words, similar to the air guiding ribs 316, the first ends 532 and the second ends 533 of the air guiding protrusions are circumferentially distributed on circular arcs of concentric circles with different radii, so that the air flow flowing out of the air outlet 510 can form a spiral air flow, and the outer wall of the inner container is cooled by strong cold-hot convection.

Of course, in other alternatives of the present embodiment, the air outlet 510 may be formed in a spiral shape or an inclined strip shape instead of the air guiding protrusion 530, so that the cool air flowing out from the air outlet 510 may form a rotating air flow with a uniform direction.

In this embodiment, when the heating element adopts the heating plate 400 and the air outlets 510 are disposed on the heat insulation cover 120, the distribution of the plurality of air outlets 510 is similar to that of the air outlets 510 disposed on the electromagnetic coil 300, and will not be described herein.

It should be noted that the cooking appliance in the embodiment of the present utility model may be an electric cooker or an electric pressure cooker, or may be other electric products for cooking food, and the cooking appliance in the embodiment of the present utility model may have various functions such as cooking porridge, cooking soup, and the like, in addition to the function of cooking rice.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
