Problems solved by technology

The existing combined burners on the market are all dominated by atmospheric combustion, supplemented by far-infrared combustion, and are subject to certain restrictions in terms of energy saving and exhaust emissions.
[0004] In addition, whether it is an atmospheric burner, an infrared burner, or a combination of thick and light burners on the market, the ignition needle and the induction needle are either placed in the center of the burner fire cover or placed between the inner and outer ring fires. This design will not only lead to a large number of heating blind areas on the upper surface of the fire cover, but also make the ignition needle and induction needle endure high temperature heating for a long time, resulting in a reduction in the service life of the ignition needle and induction needle

Embodiment 1

[0042] Such as figure 1 with figure 2 As shown, the present invention provides a burner, including an inner ring fire burner and an outer ring fire burner, at least one of the inner ring fire burner and the outer ring fire burner is composed of the first burner body and the second burner Body composition, wherein the first burner body is a partially premixed atmospheric burner, and the second burner body is a fully premixed infrared burner. The inner ring fire burner and the outer ring fire burner may also comprise only the first burner body or the second burner body.

[0043] In this embodiment, in order to improve the combustion efficiency and achieve better energy-saving efficiency, the burner preferably includes four burner bodies, which are respectively the first burner body 1 of the inner ring, the second burner body 2 of the inner ring, and the second burner body 2 of the outer ring. The first burner body 3 and the second burner body 4 of the outer ring, that is, the...

Embodiment 2

[0061] Such as image 3 As shown, the structure of the burner and burner cap in this embodiment is basically the same as that of Embodiment 1, the difference is that the first outer ring air mixing chamber 31 and the outer ring second air mixing chamber 41 are divided into upper and lower layers However, the first air mixing chamber 31 of the outer ring and the second air mixing chamber 41 of the outer ring communicate with each other through the vent 8, and only one vent 8 may be provided, or multiple vents 8 may be provided.

[0062] The first gas mixing chamber 31 of the outer ring communicates with the first injection pipe 33 of the outer ring, and the premixed gas is sprayed and burned from the first outer ring fire cover 32 at the top through a plurality of gas channels 34. The port 8 enters the second gas mixing chamber 41 of the outer ring on the upper layer, and sprays and burns from the second outer ring fire cover 42 on the top.

[0063] Since the first air mixing ...

Embodiment 3

[0065] Such as Figure 4 with Figure 5 As shown, the structure of the burner and the burner fire cover in this embodiment is basically the same as that of Embodiment 1, the difference is that the center of the inner ring fire burner has a central through hole 9 that penetrates up and down, and the inner ring first The second fire cover 22 is arranged around the central through hole 9 , and the ignition pin 5 and the induction pin 6 are installed in the central through hole 9 . Since the ignition needle 5 and the induction needle 6 are arranged at the center of the burner cap, there is no need to additionally arrange the permanent flame channel 7 in the first embodiment.

[0066] The burner fire cover of the inner ring fire and the burner fire cover of the outer ring fire in this embodiment are still an integral structure, wherein, the second fire cover 22 of the inner ring and the second fire cover 42 of the outer ring are the same infrared combustion plate, the combustion ...

Abstract

The invention relates to a combustor fire cover, a combustor and a gas stove. The combustor comprises an inner ring fire combustor and an outer ring fire combustor; the inner ring fire combustor and / or the outer ring fire combustor consist of first combustor bodies and second combustor bodies; the first combustor body and the second combustor body are an atmospheric combustor and an infrared combustor; the first combustor body consists of a first gas mixing cavity, and one or more first fire covers arranged at the top of the first gas mixing cavity; the second combustor body consists of a second gas mixing cavity, and one or more second fire covers arranged at the top of the second gas mixing cavity; and the first fire cover is mounted in the second fire cover in an embedding manner. The combustor fire cover is higher in utilization rate of the heating area, and hardly has heating blind area; atmospheric combustion is adopted in an infrared combustion area, infrared combustion is adopted in an atmospheric combustion area, and the two combustion modes are fused to greatly improve the combustion efficiency; and the firepower is higher, so that Chinese food is cooked more properly.

Description

technical field [0001] The invention relates to a gas stove, in particular to a combined burner and a burner fire cover installed on the gas stove and integrating atmospheric combustion and infrared combustion. Background technique [0002] Existing burners are generally in two forms, one is an atmospheric burner, and the other is an infrared burner. Among them, the atmospheric burner belongs to the partial premixed combustion method, and the high-temperature flame generated mainly heats the heating object by means of convective heat exchange. There are chemical heat loss and physical heat loss in the process of heating the heating object by the flame. Because the concentration of the premixed gas is relatively high, the stability of the atmospheric burner is better during use, and the heat load adjustment is relatively large. The infrared burner belongs to the complete premixed far-infrared radiation combustion method. The gas uses the entire amount of air required for the...
