Description
Technical Field
The utility model belongs to the field of gas stoves, and particularly relates to a burner fire cover for a gas stove.
Background
The existing kitchen range burner generally uses the traditional fire cover, the structure of the traditional fire cover is generally an annular fire cover, it is formed by annular top wall, annular inner side wall and annular outer side wall, the bottom of the annular fire cover is formed with the annular through groove, open along its circumferencial direction on the annular outer side wall of the annular fire cover has a plurality of main fire holes. In order to pursue higher efficiency, each manufacturer is improving primary air injection coefficient when developing the combustor, and flame is serious after primary air injection coefficient is improved.
In order to eliminate the above-mentioned drawbacks, there are also flame stabilizing devices provided on the flame cover, such as the flame stabilizing device disclosed in the external flame cover of burner disclosed in patent No. ZL201210418583.0 (issued publication No. CN 102913911B), which can perform the flame stabilizing function to some extent, but the flame stabilizing effect is still affected if the velocity of the flame stream for stabilizing flame flowing out from the flame stabilizing passage is too high. And because the flame stabilizing channel and the horizontal surface form an acute angle of 0-60 degrees, the overflow liquid easily flows into the flame stabilizing channel to cause blockage in the use process of the kitchen range; in addition, because the inner end of the flame stabilizing channel is communicated with the gas mixing chamber, the overflow liquid can enter the gas mixing chamber through the flame stabilizing channel, and the overflow liquid or dirt accumulated after a long time can cause adverse effect on the circulation of air flow in the gas mixing chamber, so that the ignition and the flame transfer are poor, and the normal combustion of fuel gas is further affected.
As shown in the patent publication No. ZL201621253862.6 (issued publication No. CN 206361752U), the flame separation preventing mechanism comprises a fire cover body and a disc-shaped cover plate covered on the fire cover body, main fire holes distributed at equal intervals in circumference are formed in the annular side wall of the fire cover body, first protrusions corresponding to the main fire holes are arranged on the upper end surface of the fire cover body, grooves are formed between adjacent first protrusions, second protrusions are arranged on the upper surface of the first protrusions, which is close to one end of the inner side wall of the fire cover body, the inner surface of the disc-shaped cover plate is attached to the upper surface of the second protrusions, and a flame stabilizing groove is formed in a gap between the disc-shaped cover plate and the outer side wall of the fire cover body.
As can be seen from the figure, the edge of the disc-shaped cover plate of the patent extends downwards to form a blocking edge which is blocked above the main fire hole and the flame stabilizing groove, so that overflow can be prevented from flowing into the main fire hole or the flame stabilizing groove. However, the distance between the blocking edge and the fire cover is not precisely designed, and if the distance is too large, the gas flow flowing out of the main fire hole easily collides with the blocking edge, so that the flow speed of the gas flow is influenced; if the distance is too small, there is still a risk that the spillover falls into the main fire hole.
In addition, the flow speed of the gas flow flowing out of the flame stabilizing groove cannot be controlled, and if the flow speed of the gas is large, the flame stabilizing effect is poor.
Or as shown in the patent publication No. ZL201310059405.8 (the issued publication No. CN 103162292B), the outer fire cover of the burner is provided with a flaring section to reduce the flow velocity of the fuel gas and improve the flame stabilizing effect; the lower end surface of the baffle part is provided with an inclined surface with high inside and low outside so as to prevent the overflow from blocking the main fire channel and the flame stabilizing channel. The fire cover connects adjacent main fire holes into a whole through the strip-shaped flame stabilizing holes, and can achieve a better flame stabilizing effect. However, the flame stabilization of the main flame is mainly due to the stabilization of the flame base, and the flame stabilization flame of the patent cannot be aligned with the main flame base for heating.
In view of the above, the current burner fire cover needs to be improved in terms of flame stabilization and prevention of overflow from blocking the fire hole.
Disclosure of Invention
The present utility model has been made in view of the above-mentioned problems occurring in the prior art, and an object of the present utility model is to provide a burner fire cover for a gas range, which can achieve a better flame stabilizing effect by ensuring that a gas flow for flame stabilizing is directed at a main flame root.
Another technical problem to be solved by the present utility model is to provide a burner fire cover for a gas stove, which can achieve the purpose of flame stabilization by reducing the flow rate of the gas flow for flame stabilization.

In order to achieve good anti-blocking and flame stabilizing effects, the gap distance d is 0.5-1.5 mm. The gap between the baffle edge and the cover body enables the overflow liquid to drop vertically without falling into the main fire channel and the flame stabilizing channel, but the gap cannot be too large, otherwise, the air flow of the main fire channel is impacted to influence the air flow speed, and the gap cannot be too small, otherwise, the anti-blocking effect is reduced.
Preferably, the gap distance d is 0.8-1.2 mm.
In order to further improve the anti-blocking and flame stabilizing effects, the bottom end surface of the blocking edge is higher than the upper edge of the main fire channel, so that the flame stabilizing air flow can impinge on the blocking edge to be downwards diffused, the root of the main flame is heated, and the air flow of the main fire hole cannot impinge on the main fire hole to influence the air flow speed.

In order to enable the combustion gas flow for stabilizing the flame to smoothly flow out of the annular groove, the top of the inner side wall of the annular groove is higher than the top of the outer side wall of the annular groove. The structure has the functions of facilitating the flow of the fuel gas for stabilizing the flame from the groove, preventing the interruption of the fuel gas and affecting the flame stabilizing effect; on the other hand, even if the overflow liquid enters the annular groove, the overflow liquid can not flow into the flame stabilizing channel.

The fuel gas for stabilizing flame flows from the inner flame stabilizing groove to the outer flame stabilizing groove, the flow area is increased, the pressure is reduced, the flow speed is reduced, and the flame stabilizing effect can be very good.
In order to control the size of the flame stabilizing fire, the vertical distance D3 between the bottom end surface of the baffle edge and the outer flame stabilizing groove is larger than D1 and smaller than D2, and the D3 is arranged between the D1 and the D2, so that the flame stabilizing gas flow can be impacted to the baffle edge and then spread in the direction of the main fire channel, and is aligned to the gas root of the main flame for heating, and the flame stabilizing effect is better; and the size of D3 can determine the size of the flame stabilizing flame, and the flame stabilizing effect on the main flame can be influenced due to the fact that the flame stabilizing flame is too large or too small.
One structure of the main fire channel is as follows: the main fire channel is a main fire hole formed in the peripheral wall of the cover body, and the main fire hole is inclined from inside to outside and has the effect of self-stabilizing flame.
