In recent years, as the standard of living of people increases, the number of household cookers has rapidly increased, and is also increasing at a rate of about 7% per year. In the gas appliance market, a gas cooker has become one of kitchen appliances indispensable to homes, and has occupied a mainstream position. With the continuous research of different manufacturers on gas cookers, the problems caused by the inherent deficiency of the gas cooker design technology are more and more emphasized by research personnel, and the main technical problems are as follows: the national standard stipulates that the heat efficiency of the embedded gas cooker is more than 50%, the heat efficiency of the table type gas cooker is more than 55%, in the actual product development test, the actual test heat efficiency of the embedded type household gas cooker is between 50% and 54% on average (the completely premixed type combustion appliance adopts an infrared combustion principle or adopts a blowing mode to prevent external convection wind from influencing and accumulating heat energy, and the embedded type household gas cooker and the table type household gas cooker of the technology are not included), the heat efficiency is about five percent lower than the actual test heat efficiency of the table type household gas cooker on average, and the test comparison calculation shows that the heat loss of the table type household gas cooker is about nine percent higher than the average of the table type household gas cooker. Because of the limitation of the design structure, when the embedded gas cooker is actually combusted, the supplied air is always lower than that of the table household gas cooker, therefore, in order to ensure that the concentration of CO in the combustion flue gas does not exceed the standard, the height of the pot support is generally designed to be increased so as to be beneficial to the air supply, although the concentration of CO in the combustion flue gas does not exceed the standard, the thermal efficiency of the embedded gas cooker is difficult to reach the standard of the thermal efficiency of the table gas cooker, which is a development difficulty in the combustion technology.
