Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a heating device and cooking equipment. Background Art

[0002] Due to the structural layout of the integrated stove steam oven, the heating tube and the circulating fan cannot be installed on the back of the inner pot. In order to achieve the effect of multi-sided heating and hot air baking, in addition to the upper and lower heating tubes, heating tubes and circulating fans are generally installed on the left and right sides. The inner pot of the integrated stove steam oven has a large left-right span, and it is difficult to achieve a uniform temperature on the left and right sides by installing the heating tube on one side.
