Description

Burner fire cover

Technical Field

The utility model relates to a domestic gas cooking utensils field especially relates to a domestic gas stove's inner ring fire lid.

Background

At present, a fire cover of a gas stove generally comprises an inner ring fire cover and an outer ring fire cover, and the heating mode of a pot body is basically a mode of combining outer ring flame and inner ring flame, wherein when the gas stove is used, the appeal of a plurality of users is that the firepower of the inner ring and the outer ring can be synchronously changed, and the minimum fire can be made very small. The function of synchronous small fire is realized to the improvement from the valve body generally to prior art, but because the regulation of the outer lane in the current valve body makes the gas passageway of outer lane belong to different passageways, need adjust the inner lane little unchangeably earlier in rotatory regulation, then continue to rotate and then adjust the outer lane little slowly thereby realize synchronous small fire, can't realize all being synchronous regulation at the arbitrary in-process of adjusting little. In addition, because the range of the maximum load and the minimum load of the inner ring is relatively large, the small fire cannot be made very small, such as about 500W, but cannot be made within 200W, and therefore, the inner ring fire cover needs to be further improved.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present invention is to provide a burner fire cover capable of reducing the load of the inner ring fire cover in view of the above-mentioned current situation of the prior art.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: this combustor fire lid, including the fire lid body, the fire lid body is including roof and by the outer rampart of this roof periphery downwardly extending, its characterized in that: the fire-fighting device is characterized by further comprising an inner ring wall arranged at intervals with the inner side and the outer side of the outer ring wall, a central cavity is formed by the inner ring wall and the outer ring wall, a peripheral cavity is formed by the inner ring wall and the outer ring wall, first fire outlets communicated with the peripheral cavity are formed in the outer ring wall at intervals along the circumferential direction, at least two fire outlets are formed in the top wall at intervals along the circumferential direction, inlets of the fire outlets are formed in the inner ring wall, outlets of the fire outlets are formed in the outer ring wall, outlets of the fire outlets are located above the first fire outlets, and the outlet caliber of each fire outlet is smaller than the aperture of the first fire outlet.

The fire protection device further comprises a fire protection channel positioned below the fire outlet channel, an air inlet of the fire protection channel is arranged on the inner ring wall, an air outlet of the fire protection channel is arranged on the outer ring wall, and an air outlet of the fire protection channel is positioned below an outlet of the fire outlet channel. Because each fire outlet channel can realize the small-load combustion of the inner ring fire cover, wherein each fire outlet channel is communicated with the central cavity, and the fire protection channel is also communicated with the central cavity, the intensity of a fire hole formed by the air outlet of the fire protection channel can be changed little in the using process, and the fire hole is not easy to leave flame, so that the burner has better and more stable fire protection capability than the conventional burner, and particularly when the minimum fire is the small-load combustion.

Furthermore, the outlet of the fire outlet channel comprises a first outlet and a second outlet which are positioned at two sides of the air outlet of the fire protection channel, and the first outlet and the second outlet and the air outlet of the fire protection channel jointly form a fire protection part corresponding to the thermocouple. The first outlet, the second outlet and the air outlet of the fire protection channel are distributed according to the positions of the equilateral triangles, and the purpose is as follows: if the inner ring fire cover rotates left and right in the placing process, flame can be well and uniformly burnt to the thermocouple head, so that the temperature of the thermocouple head cannot be too high or too low.

Furthermore, the outer ring wall of the fire cover body is circumferentially provided with a groove below the first fire outlet, and the outer ring wall is also provided with a flame stabilizing hole intersecting with the groove, and the flame stabilizing hole penetrates through the groove and is communicated with the first fire outlet. The pressure stabilizing part consisting of the groove and the flame stabilizing hole can effectively stabilize the first fire outlet, thereby obviously improving the combustion efficiency of the gas stove.

In order to realize that the inner ring fire cover can form double fire, preferably, every other one or more than one first fire outlet holes are also provided with at least two second fire outlet holes communicated with the peripheral cavity at intervals.

Compared with the prior art, the utility model has the advantages of form central cavity and the periphery cavity that has independent center fire and periphery fire between the interior rampart of ring fire lid and interior rampart and the outer rampart, wherein the center fire is gone out the fire passageway by each of intercommunication central cavity and is formed the little load burning in order to realize the inner ring fire lid, and the holistic burning load of inner ring fire lid then comprises center fire and periphery fire, under the prerequisite that satisfies the whole burning load that does not change the inner ring fire lid, can also realize the little load burning.
