Description
Technical Field
The utility model belongs to the technical field of gas stoves, and particularly relates to a burner fire cover for a gas stove and a burner using the burner fire cover.
Background
The burner of the existing gas cooker is generally provided with an outer ring fire cover and an inner ring fire cover, wherein the inner ring fire cover is generally a cylinder, a plurality of round fire holes are formed in the side wall of the cylinder along the circumferential direction, and the included angle between the inclined angle of the fire holes and the horizontal plane is generally 20-40 degrees. When the burner works, the flame of the inner ring is obviously sprayed outwards in an inclined way, and an annular heating ring is formed when the flame contacts with the bottom of the pan, so that the bottom of the pan is heated unevenly. In addition, the inner ring fuel gas of the burner is directly sprayed out from the fire hole of the inner ring fire cover without buffering, so that the air flow speed at the fire hole is high, and the inner ring flame is not easy to stabilize. An inner ring fire cover for a gas stove, as disclosed in chinese patent No. ZL201020103772.5 (issued to publication No. CN 201599854U), is an inner ring fire cover comprising a ring-shaped cover base and a protective cover disposed on top of the cover base, wherein the outer annular wall of the cover base is uniformly provided with a plurality of fire holes along the circumferential surface. In order to improve the combustion efficiency of the fuel gas input to the inner ring fire cover, the fuel gas is combusted more fully, a plurality of central through holes isolated from the fuel gas chamber are arranged in the inner ring fire cover, and secondary air supply required by the fuel gas combustion is achieved through the circulation of air in the central through holes. However, in the actual use process, since the inner ring fire cover is positioned at the center of the bottom of the pan, for a common frying pan, the distance between the inner ring fire cover and the bottom of the pan is closest, so that the effective space above the central through hole of the inner ring fire cover is very narrow, the effect of secondary air supply is reduced, and sometimes the bottom of the pan is excessively close to the central through hole of the inner ring fire cover to almost block the central through hole, so that the central through hole does not play any role. On the other hand, in the actual use process, dirt often drops on the inner ring fire cover along the bottom of the pan, or directly drops into the gas stove through the central through hole, so that the internal structure of the gas stove is polluted, and the gas stove is not easy to clean.
In addition, the structure of the separation design of the inner ring fire cover and the outer ring fire cover of the existing kitchen range burner has the following problems: 1. after the inner ring fire and the outer ring fire are separately designed, the flame stabilizing structure of the inner ring fire cover and the flame stabilizing structure of the outer ring fire cover are required to be respectively designed, so that the structure of the whole burner is relatively complex, the cost is increased, the flame stabilizing effect is not ideal, the flame stabilizing holes are easy to block, once the flame stabilizing holes are blocked, the phenomena of flame release, ignition failure and flame extinction are easily caused, and the thermocouple is difficult to maintain. 2. Because there is the problem of inner and outer ring fire, in order to make the inner ring fire fully burn, need design secondary air intake to supplement the inner ring fire, the combustor on the market at present mainly adopts from chassis to supplement and from the panel to supplement two modes to solve the secondary air intake problem, to the combustor of supplementing the secondary air from the chassis, it is comparatively difficult to lead to secondary air intake clean.
