Abstract

The utility model relates to a household gas stove burner cover comprising a burner cover body and the side surface of the burner cover is provided with a plurality of main fire holes. The lower end surface of the burner cover body is provided with a mixing chamber; the mixing chamber is communicated with the main fire holes; over or under the main fire holes are provided with a flame stabilizing groove; the inner end surface of the flame stabilizing groove is provided with a plurality of flame stabilizing holes connected with the flame stabilizing groove; and the flame stabilizing holes are communicated with the mixing chamber. The household gas stove burner cover is characterized in that the flame stabilizing groove is a horizontal or annular groove with a structure of a low outside and high inside. With the employment of the horizontal or annular flame stabilizing groove with the structure of the low outside and high inside, discharged liquid is less likely to enter the flame stabilizing groove during cooking; the external diameter of the upper surface of the flame stabilizing groove is larger than the external diameter of the lower surface thereof; and the communication between the flame stabilizing groove and the main fire holes further reduces possibility that the flame stabilizing groove is blocked due to entrance of the discharged liquid.

Description

A kind of household gas range fire cover

Technical field

The utility model relates to gas stove burner technical field, especially refers to a kind of household gas range fire cover with steady flame effect.

Background technology

Existing cooker burner is generally used traditional fire cover, the structure of tradition fire cover is generally ring-shaped fire cover, it consists of annular upper wall, annular inboard wall and annular outboard wall, the bottom of ring-shaped fire cover is formed with annular through groove, on the annular outboard wall of described ring-shaped fire cover, along its circumferencial direction, have several main fire holes, because traditional fire cover, adopt single fire hole, so there is the unstable easy circuit fire phenomenon of air-flow.In order to eliminate above-mentioned defect, also there is at present fire cover to be provided with steady flame device, if Chinese patent Granted publication number is the steady flame device disclosed in the < < burner outer fire cover > > of CN102913911A, adopt such structure, although can play to a certain extent steady flame effect, but because steady flame passage is horizontal by the acute angle of 0～60 °, cause the steady flame passage of the in use easy inflow of discharge of kitchen range to result in blockage; In addition, because the inner end of steady flame passage is communicated with mixing chamber, so discharge can enter mixing chamber by steady flame passage, discharge or the dirt of long-time rear accumulation can cause harmful effect to the circulation of air-flow in mixing chamber, and then affect the normal combustion of combustion gas.Therefore,, for current cooker burner fire cover, still need further improvement.

Utility model content

Technical problem to be solved in the utility model is the present situation for prior art, and a kind of household gas range fire cover with better steady flame effect is provided.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of household gas range fire cover, comprise the fire cover body with multiple main fire holes, this fire cover body lower surface is provided with mixing chamber, this mixing chamber is communicated with main fire hole, above or below main fire hole, be provided with a steady flame groove, this steady flame groove inner face is provided with the stable flame hole that several are attached thereto, this stable flame hole is communicated with mixing chamber, it is characterized in that the cannelure that described steady flame groove is level or outer low and inner high structure, so that the discharge in cooking process is not easy to enter steady flame groove and then by its obstruction.

As further improvement of the utility model; the upper surface external diameter of described steady flame groove is greater than lower surface external diameter; adopt such structure; when discharge is because Action of Gravity Field is when dirty; the upper surface of steady flame groove can form " umbrella " with the effect of blocking to the external port of steady flame groove, further reduces discharge and enter the probability of steady flame groove.

Further, described steady flame groove communicates with described main fire hole, can make the discharge that enters on a small quantity steady flame groove flow away by main fire hole, thereby the probability that steady flame groove stops up is reduced.

Described stable flame hole can be arranged at intervals between main fire hole, being also symmetricly set between main fire hole of determined number not.

Compared with prior art, the utility model has the advantage of: owing to having adopted the steady flame groove of annular of level or outer low and inner high structure, so that the discharge in cooking process is difficult for entering steady flame groove, in addition, the upper surface external diameter of steady flame groove is greater than lower surface external diameter, and the design that steady flame groove communicates with main fire hole has further reduced that discharge enters steady flame groove and then by the probability of its obstruction.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

Embodiment 1, as shown in Figures 1 to 5, this household gas range comprises that by fire cover side has the fire cover body 1 of multiple main fire holes 11, this fire cover body lower surface is provided with mixing chamber 2, this mixing chamber 2 is communicated with main fire hole 11, below main fire hole 11, be provided with a steady flame groove 12, these steady flame groove 12 inner faces are provided with the stable flame hole 13 that several are attached thereto, and this stable flame hole 13 is communicated with mixing chamber 2.

As shown in Figure 3, the cannelure that steady flame groove 12 is horizontal structure, so that the discharge in cooking process is not easy to flow into steady flame groove 12.The upper surface outer diameter D of steady flame groove 12 is greater than lower surface outside diameter d, adopts such structure, and when discharge is because Action of Gravity Field is when dirty, the upper surface of steady flame groove 12 can form and block effect its external port, further reduces discharge and enter the probability of steady flame groove 12.As shown in Figure 5, above-mentioned steady flame groove 12 communicates with main fire hole 11, can make the discharge that enters on a small quantity steady flame groove 12 flow away by main fire hole 11, thereby the probability that steady flame groove 12 stops up is reduced.

In the above-described embodiments, described stable flame hole 13 communicates with described mixing chamber 2, thereby make the combustion gas of steady flame can by stable flame hole 13, arrive from mixing chamber 2 the steady flame groove 12 communicating with it, fuel gas flow occurs to turn and the sudden enlargement meeting of circulation area decreases air velocity, thereby make the air velocity of combustion gas and burning velocity reach steady in the exit of steady flame groove 12, and the combustion gas of flowing out steady flame groove 12 is not steadily from flame when burning, and the steady flame scope that had both increased flame also can play the effect of the main fire hole combustion gas root temperature of heating.

Preferably, stable flame hole 13 can be arranged at intervals between main fire hole 11, being also symmetricly set between main fire hole 11 of determined number not.

Embodiment 2, is with the difference of embodiment 1: as shown in Figure 6, the cannelure that steady flame groove 12 is outer low and inner high structure, so that the discharge in cooking process is difficult to flow into steady flame groove 12 and then by its obstruction.
