Detailed Description

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

As shown in FIGS. 1 to 4, the preferred embodiment of the present invention is shown. The burner fire cover for the gas stove comprises a fire cover body 1, at least two upper fire cover bodies 2 are formed on the upper surface of the top of the fire cover body 1 at intervals along the circumferential direction, each upper fire cover body 2 protrudes out of the upper surface of the top of the fire cover body 1, and a groove 11 for guiding overflowing liquid and/or secondary air is formed between the adjacent upper fire cover bodies 2 and at the position adjacent to the inner end. This combustor fire lid has two at least protrusions in the lid body 2 of firing of going up of 1 upper surface of fire lid body on fire lid body 1, the fire hole top-down of each lid body 2 of going up fire is the echelonment and distributes generally, lower fire hole is located the root position of going up the fire hole, when great pressure or great primary air flow rate appear to the fire lid, strengthen the steady flame effect of combustor, in addition between the adjacent lid body 2 of going up fire, the position adjacent inner has the recess 11 that is used for water conservancy diversion overflow and/or guide secondary air, can avoid the influence of overflow to each fire lid body 1 on the one hand, on the other hand can accelerate the replenishment of secondary air, can more promote the abundant burning of each fire lid body 1.

Specifically, each ignition cover body 2 comprises an outer side wall 12 far away from the groove 11, a first inner side wall 13 and a second inner side wall 14 adjacent to the corresponding groove 11, wherein at least two inner ignition holes 131 are formed in the first inner side wall 13 and/or the second inner side wall 14, and at least two outer ignition holes 121 are formed in the outer side wall 12. The outer fire holes 121 and the inner fire holes 131 can be independently controlled by the outer ring gas channel and the inner ring gas channel respectively, so that a user can conveniently and independently control the inner fire holes 131 to be used for heating the small pot when the outer fire holes 121 are closed. In this embodiment, only have and seted up two at least interior fire holes 131 on the first inside wall 13, each interior fire hole 131 is from low to high echelonment gradually from bottom to top, wherein, the flame of whole interior fire hole 131 of whole burner fire lid presents from bottom to top, by outer and interior ladder distribution, lower fire hole is located the root position of going up fire hole, when great pressure or great primary air flow rate appear to the fire lid, strengthen the steady flame effect of combustor, reduce and take off a fire and take place, and the arrangement of the first inside wall 13 at each interior fire hole 131 place has different fire hole depths, the fire hole that the fire hole depth is great has increaseed air flow resistance, can avoid this type of fire hole to take off a fire when pressure is big or primary air flow rate is big, and then maintain the normal combustion of all the other fire holes. In order to prevent the ignition lid body 2 from being clogged with the spilled liquid, the top end of each ignition lid body 2 has a guide slope 21, and the guide slope 21 is gradually inclined from high to low toward the second inner side wall 14. The top end of each upper fire cover body 2 is provided with a guide slope 21, and the guide slope 21 is gradually inclined towards the second inner side wall 14 from high to low, so that overflowing liquid generated in the cooking process can be more inclined to flow towards the side of the second inner side wall 14 without the fire holes, and in addition, each upper fire cover body 2 can also be used as a 'pot support' for supporting a pot.

In order to heat the pot bottom more uniformly in the radial direction of the fire cover body 1, preferably, the fire cover body 1 further includes an outer peripheral wall 15 extending downward from the outer edge of the top, the outer peripheral wall 15 is provided with at least two fire holes 151 at intervals along the circumferential direction, and the fire holes 151 are provided with ignition holes 1511 communicated with the inner fire holes 131 and/or the outer fire holes 121 of the upper fire cover bodies 2. The fire outlet hole 151 of the fire cover body 1 comprises the ignition hole 1511, and each ignition hole 1511 is communicated with the inner fire hole 131 and/or the outer fire hole 121 of the upper fire cover body 2, so that the quick ignition can be realized by quickly transmitting fire to each upper fire cover body 2 in the state that the ignition hole 1511 is ignited, and the quick ignition can be realized. In order to achieve the ignition of the fire outlet 151 and the ignition hole 1511, it is preferable that the ignition hole 1511 is communicated with the inner fire hole 131 and/or the outer fire hole 121 of the upper fire cover 2 through the strip seam 16. The ignition hole 1511 conducts fire through the strip-shaped seam 16 communicated with the inner fire hole 131 and/or the outer fire hole 121 of the upper fire cover body 2, and has the characteristic of quick fire conduction. In order to realize the flame stabilization of the inner fire holes 131 of the upper fire lid 2, the first inner sidewall 13 of the upper fire lid 2 is provided with a flame stabilizing groove 132, and the flame stabilizing groove 132 intersects with the strip-shaped slot 16. Firstly, the flame holding groove 132 can be arranged to enable the inner fire hole 131 on the first inner side wall 13 to have better flame holding effect, and secondly, the strip-shaped slits 16 intersect with the flame holding groove 132 to accelerate the flame transfer speed to the first inner side wall 13. Finally, in order to prevent the overflow liquid remaining in the groove 11 from blocking the inner fire holes 131 on the first inner side wall 13 of the upper fire cover 2, the center lines of the inner fire holes 131 on the first inner side wall 13 of the upper fire cover 2 and the outer fire holes 121 on the outer side wall 12 are both disposed obliquely upward (refer to fig. 3 and 4). The center lines of the inner fire holes 131 and the outer fire holes 121 are both inclined upward. Each upper fire cover body 2 is in a cone shape with a small upper part and a big lower part. Each upper fire cover body 2 is in a cone shape with a small upper part and a big lower part, so that the fire holes of the upper fire cover are generally distributed in a ladder shape from top to bottom, the lower fire holes are positioned at the root positions of the upper fire holes, and when the fire cover has larger pressure or larger primary air flow rate, the flame stabilizing effect of the combustor is enhanced.
