Problems solved by technology

[0002] Although the burner combined by the infrared burner and the atmospheric burner has the effect of high efficiency and low pollution to a certain extent, as far as the existing technology is concerned, the technology still has the following problems: 1. The combination method is too Simple, the atmospheric combustion structure and the infrared combustion structure act independently, without forming a complementary organic combination, resulting in the improvement of the burner efficiency mainly relying on the function of the infrared burner, and the lifting space is limited; 2. Under heavy load conditions , the infrared burner is easy to cause tempering, causing safety hazards

Embodiment Construction

[0024] The burner fire cap, burner and gas stove involved in the present invention are described in detail below with reference to the accompanying drawings.

[0025]

[0026] Such as Figures 1 to 5 As shown, the burner 10 includes a burner cap 20 , an air mixing chamber 30 , an injection pipe 40 and a mounting part 50 .

[0027] The burner cap 20 is installed on the top of the gas mixing chamber 30, and it includes a central concentrating burner cap unit 21 and two outer ring concentrating burner cap units 22.

[0028] The central energy-concentrating burner fire cover unit 21 comprises a central atmosphere type fire cover 211 and a center infrared type fire cover 212.

[0029] The central atmospheric fire cover 211 is arranged in the center in a disc shape, and the surface is densely covered with fire holes.

[0030] The central infrared fire cover 212 is arranged around the central atmospheric fire cover 211 in a ring shape, and its height is 1.3 times the height of th...

Abstract

The invention provides a burner fire cover, a burner and a gas stove. The combustion efficiency can be improved, and the backfire phenomenon can be avoided. The burner fire cover comprises a central energy-gathered burner fire cover unit and at least two outer ring energy-gathered burner fire cover units; the central energy-gathered burner fire cover unit comprises a central atmosphere type fire cover arranged in the center and a central infrared type fire cover arranged around the central atmosphere type fire cover; the at least two outer ring energy-gathered burner fire cover units are sequentially arranged around the central energy-gathered burner fire cover unit from inside to outside; each outer ring energy-gathered burner fire cover unit comprises an annular atmosphere type fire cover arranged on the inner side and an annular infrared type fire cover arranged on the outer side; the height of the central infrared type fire cover is 1.2-1.5 times that of the central atmosphere typefire cover; the height of the annular infrared type fire cover is 1.2-1.5 times that of the annular atmosphere type fire cover; the shapes of fire holes in the central infrared type fire cover and the annular infrared type fire cover are both in thin kidney shapes with the inner diameters gradually decreased and then gradually increased from the bottoms of the fire holes to the upper sides.

Description

technical field [0001] The invention belongs to the field of combustion equipment, and in particular relates to a burner fire cover, a burner and a gas stove. Background technique [0002] Although the burner combined by the infrared burner and the atmospheric burner has the effect of high efficiency and low pollution to a certain extent, as far as the existing technology is concerned, the technology still has the following problems: 1. The combination method is too Simple, the atmospheric combustion structure and the infrared combustion structure act independently, without forming a complementary organic combination, resulting in the improvement of the burner efficiency mainly relying on the function of the infrared burner, and the lifting space is limited; 2. Under heavy load conditions , Infrared burners are easy to cause tempering, causing safety hazards. Contents of the invention [0003] The present invention is made to solve the above problems, and aims to provide ...
