Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 and 2, is a preferred embodiment of the present invention. The burner fire cover for the gas stove comprises a fire cover body 1, and comprises a top wall 11 and a side peripheral wall 12 extending downwards from the outer edge of the top wall 11, the top wall 11 and the side peripheral wall 12 jointly enclose a gas mixing cavity 13, a downward-recessed area 14 is arranged in the center of the top wall 11, at least two convex parts 2 protruding upwards are arranged on the recessed area 14 at intervals along the circumferential direction, an inner peripheral wall 21 and an outer peripheral wall 22 of each convex part 2 are provided with an inner fire outlet 211 and an outer fire outlet 221 communicated with the gas mixing cavity 13, and at least two outer fire outlets 121 communicated with the gas mixing cavity 13 are arranged on the side peripheral wall 12 at intervals along the circumferential direction. The convex parts 2 of the fire cover are arranged at intervals along the circumferential direction, and the convex parts 2 are simultaneously provided with the inner fire outlet holes 211 and the middle fire outlet holes 221, so that the fire cover has two ring fires of a middle ring fire and an inner ring fire, and the side peripheral wall 12 of the fire cover also has the fire outlet holes capable of forming an outer ring fire, thereby making up the defect of heating the pot bottom area between the existing inner ring fire cover and the existing outer ring fire cover and heating the pot bottom more uniformly; in addition, the provision of the recessed region 14 can reduce the difference in height between the inner fire outlet holes 211 of the projecting portion 2 and the outer fire outlet holes 121 of the side peripheral wall 12.

Specifically, in order to realize the fire transmission of each protrusion 2, each protrusion 2 of the present embodiment includes a first connecting wall 23 and a second connecting wall 24 that connect the inner peripheral wall 21 and the outer peripheral wall 22, a fire transmission channel 25 for transmitting the flame formed by the inner fire outlet 211 to the middle fire outlet 221 is opened on the first connecting wall 23 and/or the second connecting wall 24, wherein the top wall 11 is provided with a fire transmission platform 3 for transmitting the flame of the middle fire outlet 221 to the outer fire outlet 121 on the outer top wall 11 outside the recessed area 14, a hole wall of the inner side opening 31 of the fire transmission platform 3 extends toward the middle fire outlet 221, and the outer side opening 32 of the fire transmission platform 3 is located on the side peripheral wall 12, which is favorable for realizing the transmission of the middle fire outlet 221 of each protrusion 2 to the outer fire outlet 121. In addition, the internal perisporium 21 that sets up interior fire outlet 211 in the fire lid body 1 has inclined end face 20, the bottom of this inclined end face 20 is closer than the top from the center of fire lid body 1, and the contained angle alpha that forms between the line of the top of inclined end face 20 and bottom and the central line that interior fire outlet 211 is located is the acute angle, can realize like this that the gas mixture that interior fire outlet 211 spun of each bulge 2 and primary air constitute can gather together to the centre, can utilize an ignition needle can light the gas mixture that interior fire outlet 211 spun of each bulge 2, realize the effect of being igniteed simultaneously.

The interior fire hole 211 of this embodiment is provided with two, sets up the upper and lower both sides at the inclined end face 20 of fire lid body 1 respectively, and the inclined end face 20 of fire lid body 1 still is provided with the fire hole 26 that communicates with fire transfer passageway 25 between interior fire hole 211. The arrangement mode that the fire transfer holes 26 are communicated with the fire transfer channels 25 is adopted, so that the ignited flame of the inner fire outlet hole 211 is conducted to the middle fire outlet hole 221. In order to ensure stable combustion of the fire transfer holes 26, the fire transfer holes 26 are positioned at the positions which are partially inwardly contracted along the inclined end surface 20 of the fire cover body 1 in the radial direction to form the inwardly contracted part 10, the fire transfer inlets 251 of the fire transfer channels 25 are arranged to intersect with the inwardly contracted part 10, and the fire transfer outlets 252 of the fire transfer channels 25 are communicated with one of the fire outlet holes 221. The position of the fire transfer hole 26 can be locally retracted in the radial direction, a pressure stabilizing part can be formed between the upper and lower inner fire outlet holes 211, and the pressure stabilizing part is communicated with the fire transfer inlet 251 of the fire transfer channel 25, so that the combustion efficiency of the gas stove can be obviously improved while fire transfer is stabilized. The arrangement of the depressed region 14 enables the integral fire cover body 1 to form a shape with a high periphery and a low center, overflowing liquid generated in the cooking process is easy to accumulate in the depressed region 14, in order to avoid the accumulating of the overflowing liquid, the center of the depressed region 14 is provided with a discharge port 141 for discharging the overflowing liquid, and the discharge port 141 is also provided with an ignition needle for ignition. The overflow is discharged through the discharge port 141 to avoid the accumulation of the overflow, and the discharge port 141 is arranged at the position which is just the area surrounded by the inner peripheral wall 21 of each convex part 2, so that the mixture gas sprayed from the inner fire outlet 211 of each convex part 2 can be ignited, and the effect of being ignited at the same time is realized.

To sum up, the burner fire cover of the present embodiment ignites the inner fire hole 211 of each protrusion 2 by the ignition needle, and then the fire of the inner fire hole 211 is transmitted to the middle fire hole 221 through the fire channel 25 of each protrusion 2, and at the same time, the fire is transmitted to the outer fire hole 121 by the fire transmitting platform 3, so that the burner fire cover forms three ring fires of inner, middle and outer to uniformly heat the pot bottom, and finally the overflow generated in the cooking process can be discharged through the discharge port 141.
