Energy-saving gas stove capable of adjusting space size and sealing degree of combustion heat exchange chamber

Abstract

The invention relates to the technical field of commercial kitchenware, in particular to an energy-saving gas stove capable of adjusting the space size and the sealing degree of a combustion heat exchange chamber. A user can conveniently and rapidly adjust and change the vertical relative height of a combustion mechanism in real time by controlling an adjusting mechanism, a burner assembly and thebottoms of different cookware can be tightly attached together, a cake-shaped relatively-closed heat conversion space is formed between the burner assembly and the bottoms of the different cookware,and mixed gas burning flame transversely flowing out of a flame spreader is attached to the bottom face of the cookware for heat conversion, mixed gas is subjected to high-temperature and high-strength combustion reaction in a high-airtightness small-volume large-area combustion heat exchange environment, the bottom of the cookware nearly synchronously absorbs and uses heat in a large-temperature-difference high-strength direct mode, combustion tail gas flows to the periphery through a narrow-slit flue adjusted by an annular narrow-slit discharge port and is tightly attached to the bottom faceof the cookware to flow to the outside, and the cookware can further absorb and utilize waste heat in the tail gas, so that the overall heat energy conversion efficiency of the gas stove is greatly improved.

technical field [0001] The invention relates to the technical field of commercial kitchen utensils, and specifically discloses an energy-saving gas stove capable of adjusting the space size and sealing degree of a combustion heat exchange chamber. Background technique [0002] Gas cookers are commonly used heating equipment in chemical industry, food processing and catering enterprises. The burner is used to organize the mixed combustion of gas and air, and heat the material through the heat conduction of the pot. Because the effective heat exchange area at the bottom of the pot for absorbing and transferring heat is relatively small, It is difficult to greatly improve the gas heat conversion efficiency of this type of combustion heat exchange structure. Under the condition that the pan has a limited heat exchange area and cannot be changed, the combustion reaction temperature of the gas-air mixture is increased, and the distance between the flame temperature and the frying p...

[0002] Gas cookers are commonly used heating equipment in chemical industry, food processing and catering enterprises. The burner is used to organize the mixed combustion of gas and air, and heat the material through the heat conduction of the pot. Because the effective heat exchange area at the bottom of the pot for absorbing and transferring heat is relatively small, It is difficult to greatly improve the gas heat conversion efficiency of this type of combustion heat exchange structure. Under the condition that the pan has a limited heat exchange area and cannot be changed, the combustion reaction temperature of the gas-air mixture is increased, and the distance between the flame temperature and the frying pan is increased. The temperature difference is an effective way to improve the efficiency of heat energy conversion. At present, the main factor that restricts the improvement of gas heat energy conversion efficiency is that the burner organizes the mixed combustion of gas and air to release heat and the process of heat absorption and conduction by the pot is not direct, that is to say, the burner is divided into fire parts. There is a burning flame flow distance of tens of millimeters between the fire outlet and the bottom plate of the heat exchange pot. The heat needs to flow from the fire outlet of the burner to the bottom plate of the pot for a long distance, and then diffuse and transfer to the periphery of the bottom plate after the resistance in the central area of ​​the bottom plate of the pot. And a relatively open combustion environment, so that the combustion flame and heat flow and spread over a long distance, the temperature and heat volume density are greatly reduced when reaching the bottom of the pot, and the temperature difference between the heat that can be absorbed and the bottom of the pot becomes smaller, so many Unfavorable factors are not conducive to high-quality combustion reaction, nor to high-intensity concentrated effective heat energy conversion, which greatly reduces the utilization rate of gas heat energy of combustion heat exchange equipment
