Description
Technical Field
The invention relates to a burner for a stove, in particular to a burner with a good flame stabilizing effect.
Background
At present, the fire lid of gas-cooker usually comprises roof, annular inside wall and annular lateral wall, and it has a plurality of main fire hole to open along its circumferencial direction on the annular lateral wall of fire lid, and only including the single row fire hole on the annular lateral wall of current gas-cooker fire lid, this type of patent document can refer to the chinese utility model patent of patent number ZL200520014838.2 for a gas-cooker combustor toper fire lid (grant No. CN2842216Y), can also refer to chinese utility model patent of patent number ZL201120246965.0 for a combustor fire lid (grant No. CN 202149492U). The single main fire hole combustion mode disclosed above has the disadvantages that the flame is easy to jump after combustion, the combustion area is unstable, meanwhile, the single row of fire holes not only make the combustion thermal efficiency of the gas stove low, but also make the combustion of the gas insufficient, which causes the emission of carbon monoxide gas, and aggravates the environmental pollution, for this reason, in order to stabilize the main fire holes, it is often adopted to arrange the flame stabilizing holes capable of pulling the main fire holes above and/or below the main fire holes, for example, the Chinese utility model patent ZL201621024734.4 (No. CN205979785U) of the applicant forms a gas mixing chamber between the annular top surface of the body and the inner ring wall and the outer ring wall respectively extending downwards from the inner side edge and the outer side edge of the annular top surface, a plurality of main fire holes communicated with the gas mixing chamber are arranged on the body at intervals, the annular top surface of the gas mixing chamber is provided with an inner ring part and an outer ring part, the top end of the inner ring part is higher than the top layer end of the outer ring part, each main flame hole is circumferentially arranged on the outer ring part, a plurality of flame stabilizing holes communicated with the gas mixing chamber are circumferentially arranged on the inner ring part, the outlet of each flame stabilizing hole faces the main flame hole, and the outlet of each flame stabilizing hole is positioned above the outlet of the main flame hole, wherein the flame stabilizing holes face the main flame holes, the flame in the flame stabilizing holes faces the root of the flame in the main flame holes and burns, the problem of backfire is solved, the flame stabilizing holes can be combined with the main flame, the heating efficiency is improved, but the holes of the flame stabilizing holes of the flame cover are relatively small compared with the main flame holes and are easily blocked by soup overflow liquid, and the user hardly cleans the flame stabilizing holes thoroughly, so that the main flame holes are unstable, are used for a long time and are often flameout accidentally.
Disclosure of Invention
The first technical problem to be solved by the present invention is to provide a burner, in which the flame stabilizing hole is not easily blocked by the overflow, in view of the above-mentioned prior art.
A second technical problem to be solved by the present invention is to provide a burner that is easy to clean even when a flame stabilizing hole is clogged with a spill, in view of the above-mentioned state of the art.
The technical scheme adopted by the invention for solving the technical problems is as follows: this a combustor for gas-cooker, including outer ring gas mixing chamber, outer ring gas mixing chamber is including being the annular and concentric inner circle wall and the outer lane wall that sets up of interval and the diapire of connecting inner circle wall and outer lane wall, inner circle wall and outer lane wall top cover have outer ring fire lid, outer ring fire lid is including annular body, the annular top surface of body with respectively from the inboard edge of this annular top surface, outside edge downwardly extending with the inner ring wall that the inner circle wall offseted, with the outer ring wall that the outer lane wall offseted, its characterized in that: the outer ring wall and the outer ring wall form a flame stabilizing channel which is communicated with the outer ring gas mixing chamber and has a V-shaped section.
