Description

Fire cover for gas stove

Technical Field

The utility model relates to a combustor of gas cooking utensils especially relates to a fire lid for gas-cooker.

Background

At present, most of the traditional burner fire covers sold in the market are milled in one groove, namely, a fire striking groove is milled in the top of the fire cover body, and the burner fire cover is easily deformed due to the fact that the fire cover body is disconnected in the fire striking groove, so that the fire striking effect is influenced. For example, a similar fire transfer structure is disclosed in a chinese utility model patent "gas furnace end with fire transfer device and flameout protection function" with a patent number of 201220464214.0 (with a publication number of CN 202813375U), wherein an outer ring fire spray ring is provided with a plurality of outer ring fire spray holes, and the outer ring fire spray holes are further provided with an outer ring fire transfer device, the outer ring fire transfer device is composed of a fire striking table arranged on the inner side wall of the outer ring fire spray ring, outer ring fire transfer holes arranged on the fire striking table and the outer ring fire spray ring, and an outer ring fire transfer groove, the outer ring fire transfer holes are communicated with the outer ring fire transfer groove, the outer ring fire transfer holes and the outer ring fire transfer groove are communicated with one outer ring fire spray hole, thereby realizing rapid fire transfer; this pass fire groove of structure is open, has to pass fire and is the linear type promptly to pass the fire groove and expose at outer ring fire lid surface, such design has a benefit, exactly passes the supply of fire inslot secondary air very abundant, and open passes fire groove can guarantee to pass the supply of secondary air when fire inslot flame burns, is favorable to flame burning and passes fire, has the quick characteristics of passing fire.

However, the open fire transfer slot has two disadvantages: firstly, the method comprises the following steps: the fire transfer groove is easy to block, namely soup flowing from the bottom of the pan is easy to flow into the fire transfer groove, and the fire transfer performance is influenced after the soup is blocked, which is also the main reason for the blockage and maintenance of the current fire transfer groove; secondly, the method comprises the following steps: the open type fire transfer groove has high requirements on the air door of the stove, and after the air door is opened to a large extent, too much air can cause too high air flow speed, so that fuel gas at the ignition port of the fire transfer groove is diluted to cause flame leaving or flame dropping during combustion, therefore, the structural characteristic of the open type fire transfer groove is poor in flame stabilizing property, and therefore, the fire transfer groove of the fire cover of the burner needs to be further improved.
