Abstract: Since the implementation of energy efficiency, the heat efficiency of gas stove has been constantly updated, and the energy-saving index has become the focus of competition in the cookers industry. How to improve the heat efficiency of gas stove has become an important research direction of every enterprise. In addition to the direct relationship between the heat efficiency of gas stove and the burner itself, the pan support has a great impact on the heat efficiency, especially for some high-efficiency cooking utensils nowadays, the pan support plays a vital role in improving the heat efficiency. In order to study the relationship between the pan support and the heat efficiency so as to improve the heat efficiency of the gas stove, analyzes from the perspective of heat transfer, obtains the relationship between the pan support and the improvement of the heat efficiency and carries out practical verification. Finally, it is concluded that the size of the pan support energy accumulation plate, the smoke exhaust gap and the number of layers of the energy accumulation plate can all affect the heat efficiency of the gas stove.
