Improved gas stove with secondary air channel

Abstract

The invention relates to an improved inward-turning-for-firing gas stove with a secondary air channel. The gas stove comprises a panel, a bottom case, an inward-turning-for-firing burner and a pan bracket, wherein the pan bracket comprises a bottom ring seat and legs, and the legs comprise supporting legs and horizontal legs; the gas stove further comprises a separating cover; the separating cover is provided with a central hole; a clearance is formed between the inner wall of the central hole and the periphery of the inward-turning-for-firing burner; a clearance is formed between the separating cover and the panel; and the clearance between the separating cover and the panel and the clearance between the inner wall of the central hole and the periphery of the inward-turning-for-firing burner constitute the secondary air channel. When the gas stove is in operation, the separating cover isolates gas fume completely from replenishing air, and the fume generated after gas combustion is discharged through rotation of vanes; and meanwhile, the heat absorbed by the surface of the separating cover can be radiated through the surface of the separating cover so as to heat a pan to be heated, and at the same time the internal temperature of the gas stove is reduced, which is favorable for protecting the inner devices and components of the gas stove. Through the function of the separating cover, by using special gas stove ware, the structural defects of existing embedded stoves are avoided, and the heating efficiency is improved.

Description

technical field [0001] The invention relates to a gas stove. Background technique [0002] In the current prior art, a gas stove includes a panel, a bottom shell, an internal swirling fire burner and a pot support. The pot support includes a bottom ring seat and a foot. Evenly distributed; the internal swirling fire burner includes a fire cap. The problem is: during the gas combustion process, while the high-temperature flame is heating the pot, the combustion flue gas and the combustion-promoting air are constantly mixed near the gas stove top, resulting in the low oxygen content of the secondary air supplemented by the flame root, and the gas The flame is elongated, the high-temperature area extends to the outside of the heating pot, and the heating efficiency decreases; secondly, the continuous mixing of the combustion smoke and the combustion-promoting air also reduces the temperature of the flame, the heating capacity of the flame decreases, and the heating efficiency ...

The problem is: during the gas combustion process, while the high-temperature flame is heating the pot, the combustion flue gas and the combustion-promoting air are constantly mixed near the gas stove top, resulting in the low oxygen content of the secondary air supplemented by the flame root, and the gas The flame is elongated, the high-temperature area extends to the outside of the heating pot, and the heating efficiency decreases; secondly, the continuous mixing of the combustion smoke and the combustion-promoting air also reduces the temperature of the flame, the heating capacity of the flame decreases, and the heating efficiency decreases; thirdly, the flame Heating the gas cooktop will directly cause heat loss, and at the same time affect the life of the electronic components of the cooker; fourth, the primary air supplemented by the furnace surface and the heating pot channel also contains smoke components, which make the gas combustion flame elongate and heat up. Reduced efficiency
