A burner for a gas stove

Abstract

The invention relates to a burner for a gas stove, which is characterized in that it includes a base, the base has an inner wall and an outer wall arranged at intervals inside and outside, the inner wall surrounds a central cavity for replenishing gas, and the inner wall and the outer wall share the same Surrounded by a peripheral cavity and a connecting body arranged on the base, the connecting body has a gas channel communicating with the peripheral cavity, and the inner wall of the gas channel forms an annular cavity surrounding the central hole and a flow guide provided in the annular cavity The secondary air in the central cavity can be guided into each inner fire hole by means of the flow guide. Compared with the prior art, the advantage of the present invention lies in the flow guide provided in the annular cavity surrounded by the inner wall of the gas channel. It effectively solves the current situation of insufficient secondary air replenishment in the inner wall area of ​​the burner fire cover. Each flow guide is aligned with the inner fire holes of each fire cover one by one, so that the secondary air can be supplemented accurately, and the gas combustion efficiency can be improved. At the same time The deflector can preheat the secondary air, which helps to improve the thermal efficiency of the burner.

Description

technical field [0001] The invention relates to a burner, in particular to a burner for a gas stove. Background technique [0002] At present, the fire cover of the gas stove usually includes an inner ring fire cover and an outer ring fire cover, and the heating method for the pot body is basically a combination of an outer ring flame and an inner ring flame, and the distance between the outer ring flame and the inner ring flame is The distance between the center of the bottom of the pot is relatively far, and the outer annular flame is sprayed outwards, so the bottom of the pot cannot be heated intensively, and the smoke formed by combustion stays at the bottom of the pot for insufficient time, resulting in low efficiency and waste of resources. In order to solve the above problems, a patent application No. CN201310295581.1 (authorized announcement No. CN103438453A) Chinese invention patent "an internal injection burner for gas cooker" which provides a burner, which include...

Problems solved by technology

[0002] At present, the fire cover of the gas stove usually includes an inner ring fire cover and an outer ring fire cover, and the heating method for the pot body is basically a combination of an outer ring flame and an inner ring flame, and the distance between the outer ring flame and the inner ring flame is The distance between the center of the bottom of the pot is relatively far, and the outer annular flame is sprayed outwards, so the bottom of the pot cannot be heated intensively, and the smoke formed by combustion stays at the bottom of the pot for insufficient time, resulting in low efficiency and waste of resources. In order to solve the above problems, a patent application No. CN201310295581.1 (authorized announcement No. CN103438453A) Chinese invention patent "an internal injection burner for gas cooker" which provides a burner, which includes a base, injection pipe, connecting ring, Furnace head, flue gas hood, ejector pipe are fixedly connected with the base, and the base is provided with connecting ring, furnace head and flue gas hood from bottom to top. The flame of the hole is sprayed inward, which can make the flame heat the bottom of the pot intensively and improve the thermal efficiency. However, the secondary air required for combustion in the fire hole on the inner wall of the burner of this kind of burner is often insufficient, and the current integrated fixed structure of the gas mixing chamber is not enough. Conducive to the cleaning of the cooker, especially the inside of the gas mixing chamber and the inside of the waist-shaped hole. There are more and more complaints from users that the gas mixing chamber is not easy to clean, and it is also prone to uneven heating of the bottom of the pot
