By the arrangement, on one hand, air convection circulation can be formed between the heating cavity and the inner heat insulation cavity, steam is driven to circulate in a convection manner between the heating cavity and the inner heat insulation cavity, and uniform heating is facilitated; on the other hand, because the air outlet sets up around the air intake, when steam gets into the heating chamber from interior thermal-insulated chamber, can follow the extension all around of heating chamber, promote the efficiency that steam transfer to the different positions of heating chamber, avoid the food in the heating chamber to be heated unevenly in a local part.
