The prior art realizes the changeable cavity size by at least one of the upper heat conducting plate and the lower heat conducting plate being a lifting movable heat conducting plate. However, the prior art still has structural deficiencies, and it has only one heating cavity, which greatly wastes the cavity space, has a low space utilization rate, and has no air frying function, and cannot realize the air frying function while the baking function.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content
