Background
At present, most of the traditional burner fire covers sold in the market are formed by milling a groove, namely, a igniting groove is formed in the top of the fire cover body, and the fire cover of the burner is easy to deform because the fire cover body is disconnected at the igniting groove, so that the igniting effect is affected. The invention discloses a similar fire transmission structure, as in a Chinese patent with the patent number 201220464214.0 (bulletin number CN 202813375U), wherein an outer ring fire-spraying ring is provided with a plurality of outer ring fire-spraying holes, and an outer ring fire-spraying device is also arranged on the outer ring fire-spraying weight, the outer ring fire-spraying device consists of a boss arranged on the inner side wall of the outer ring fire-spraying ring, an outer ring fire-spraying hole and an outer ring fire-spraying groove which are arranged on the boss and the outer ring fire-spraying ring, the outer ring fire-spraying hole is communicated with the outer ring fire-spraying groove, and the outer ring fire-spraying hole and the outer ring fire-spraying groove are communicated with one outer ring fire-spraying hole, so that quick fire transmission can be realized; the fire transfer groove of the fire transfer structure is open, the fire transfer groove is in a linear shape, namely, the fire transfer groove is exposed on the surface of the outer ring fire cover, so the design has the advantages that the secondary air in the fire transfer groove is sufficiently supplied, the open fire transfer groove can ensure the supply of the secondary air when the flame in the fire transfer groove burns, the flame burning and the fire transfer are facilitated, the fire transfer structure has the characteristic of quick fire transfer, but the open fire transfer groove has two bad parts, the first and the open fire transfer grooves easily cause the blockage of the fire transfer groove, namely, soup flowing from the bottom of a pot easily flows into the fire transfer groove, and the blockage influences the fire transfer performance, which is also the main reason for the blockage maintenance of the current fire transfer groove; the second, open fire transfer groove is very high to the cooking utensils air door requirement, because the air door is opened after big, and the air flow velocity is too big that once air can cause to leave the flame or take off the fire when causing the burning, therefore open fire transfer groove's structural feature is the steady flame characteristic relatively poor, consequently needs to guarantee open fire transfer groove's fire transmission performance, basically all is very little with the air door closing, but the air door is closed little to be unfavorable for the combustion efficiency of cooking utensils, also is unfavorable for the emission of flue gas, has greatly influenced the performance of cooking utensils. For this reason, further improvements to the flame propagation groove of the burner flame cover are required.
Disclosure of Invention
The invention aims to solve the technical problem of providing a burner fire cover of a gas cooker, which can improve the strength of a fire cover ignition structure and reduce the blocking probability of an ignition part.
The technical scheme adopted for solving the technical problems is as follows: the burner fire cover of the gas cooker comprises a fire cover body, wherein a gas mixing cavity is formed between an annular top wall of the fire cover body and an inner annular wall and an outer annular wall which extend downwards vertically or obliquely from the inner side edge and the outer side edge of the annular top wall, a transverse ignition hole is formed in the inner part of the fire cover body along the radial direction, and a through hole communicated with the gas mixing cavity is formed in the bottom of the transverse ignition hole, and the burner fire cover is characterized in that: the outer side of the transverse ignition hole is opened on the outer annular wall, the inner side of the transverse ignition hole is opened on the inner annular wall, and a boss is formed on the inner annular wall in a radial extending mode towards the center of the fire cover body at the peripheral wall corresponding to the inner side opening of the transverse ignition hole; the included angle alpha between the center line of the through hole and the center line of the transverse ignition hole is an acute angle, and the through hole is inclined downwards and gradually approaches the boss from the air inlet communicated with the air mixing cavity to the air outlet communicated with the transverse ignition hole.
Because the transverse ignition hole is hidden in the fire cover body, the anti-blocking performance of the ignition hole can be improved, but the problem of insufficient combustion caused by the air quantity reduction of the transverse ignition hole can be solved, and therefore, a notch is formed on the vertical end face of the boss at the lower part of the inner side opening of the corresponding transverse ignition hole. And secondary air is supplemented to the transverse ignition holes through the gaps, so that air supplement in the transverse ignition holes is improved, combustion in the transverse ignition holes is stabilized, and fire transfer performance is improved.
In order to prevent the overflow from entering the transverse ignition hole through the opening at the inner side of the transverse ignition hole, the part of the upper edge of the notch gradually inclines upwards outwards along the radial direction of the fire cover body.
Preferably, the transverse ignition hole is gradually inclined upward from an inner side opening thereof to an outer side opening thereof. The design of the inclined angle of the transverse ignition hole can strengthen the suction effect on the outside air and improve the air supply speed; on the other hand, the slope design of the transverse ignition holes has a directional flow guiding effect on secondary air, ensures that the secondary air passes through the fire outlet holes of the inner ring fire cover right opposite to the secondary air after passing through the gas mixing chamber, reduces the supply resistance of the secondary air to the inner ring flame, and ensures that the secondary air is supplied more rapidly; meanwhile, overflows entering the transverse ignition part can be prevented from entering the through hole.
In order to guide the overflow liquid, the top of the boss is downwards sunken to form a groove for guiding the overflow liquid.
Preferably, the grooves are gradually inclined downward from top to bottom.
In order to guide the overflow flowing down from the groove to flow out along the inner annular wall of the fire cover body, the groove comprises a base part integrally connected with the peripheral wall of the inner annular wall and a free part extending radially from the base part towards the center of the fire cover body, and a necking is further arranged at the joint of the base part and the inner annular wall.
Further, the groove gradually slopes downward from its free portion to its base portion.
Further, the connection part between the outer walls of the two sides of the boss and the inner annular wall is provided with an arc-shaped guide groove connected with the necking, the arc-shaped guide groove comprises a first end close to the necking and a second end far away from the necking, and the arc-shaped guide groove gradually inclines downwards from the first end to the second end.
In order to prevent the overflow flowing down from the arc-shaped guide groove from entering the inner opening of the transverse fire guiding hole through the bottom wall of the boss, the bottom wall of the boss is adjacent to the inner edge of the fire cover body, and the lowest point of the bottom wall of the boss is higher than the highest point of the second end of the arc-shaped guide groove. Meanwhile, the bottom wall of the boss is located at the edge of the inner side of the fire cover body at a distance, so that the fire transmission distance can be effectively reduced, and the fire transmission is faster.
Preferably, the distance d between the bottom wall of the boss and the inner side edge of the fire cover body is more than or equal to 0.8mm and less than or equal to 1mm. The distance that this interval that both exist can shorten the fire transmission distance of whole horizontal fire hole, simultaneously, two vertical walls of boss inwards are sunken to be formed with the breach, and this breach supplies the secondary air to get into horizontal fire hole, has improved the air supply in the horizontal fire hole, stabilizes the burning in the horizontal fire hole, improves the fire transmission performance.
The included angle alpha between the central line of the through hole and the central line of the transverse ignition hole is 30 degrees or more and less than or equal to 50 degrees. Because the transverse ignition hole is hidden in the fire cover body, on one hand, the air door can be opened greatly, so that the primary air quantity entering the through hole and the transverse ignition hole is increased, the speed is increased, further secondary air is sucked into the transverse ignition hole, and the gas, primary air and secondary air are mixed into a mixed gas and then can directly collide with the top of the boss, so that the mixing uniformity of the gas and air in the mixed gas is improved, the flow speed is reduced, and the flame stabilizing performance is improved. If the angle is too large, the area where the mixed gas and the boss collide is easily caused to be too small, and if the angle is too small, the path of the primary air quantity entering the through hole and the transverse ignition hole is easily caused to be too long, so that secondary air is not easy to be sucked.
Compared with the prior art, the invention has the advantages that the transverse ignition hole is of the hidden fire transmission groove structure hidden in the fire cover body, so that the air door can be opened to enlarge the primary air quantity entering the through hole and the transverse ignition hole, the speed is enlarged, more secondary air can be sucked into the transverse ignition hole, meanwhile, the peripheral wall of the inner opening of the inner annular wall corresponding to the transverse ignition hole radially extends towards the center of the fire cover body to form a boss, the included angle alpha between the center line of the through hole and the center line of the transverse ignition hole is an acute angle, so that the mixed gas of the fuel gas, the primary air and the secondary air can directly collide with the top of the boss, the mixing uniformity of the fuel gas and the air in the mixed gas is improved, the flow velocity is reduced, the flame stabilizing performance is improved, the flame stabilizing effect on the flame at the transverse ignition hole is realized, the secondary air supply of the internal fire transmission groove is ensured, the flame combustion in the fire transmission groove is ensured, the blockage of soup is effectively prevented, the applicability of the opening of the air door is enhanced, and the fire transmission performance is ensured under the condition that the opening of the air door is larger.

Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Example 1
As shown in fig. 1 to 4, is a preferred embodiment of the present invention. The burner fire cover of the gas cooker in the embodiment comprises a fire cover body 1, wherein a mixing cavity 13 is formed between an annular top wall of the fire cover body 1 and an inner annular wall 11 and an outer annular wall 12 which extend vertically or obliquely downwards from an inner side edge 110 and an outer side edge of the annular top wall, a transverse ignition hole 14 is formed in the inner part of the fire cover body 1 along the radial direction, a through hole 141 communicated with the mixing cavity 13 is formed at the bottom of the transverse ignition hole 14, an outer side opening 142 of the transverse ignition hole 14 is formed in the outer annular wall 12, an inner side opening 143 of the transverse ignition hole 14 is formed in the inner annular wall 11, a boss 2 is formed in the inner annular wall 11 by extending radially towards the center of the fire cover body 1 from a peripheral wall corresponding to the inner side opening 143 of the transverse ignition hole 14, and the through hole 141 extends obliquely downwards and gradually approaches the boss 2 from an air inlet communicated with the mixing cavity 13 to an air outlet communicated with the transverse ignition hole 14. And the important point is that the included angle alpha between the center line of the through hole 141 and the center line of the transverse ignition hole 14 is an acute angle alpha which is 30 DEG.ltoreq.alpha.ltoreq.50 deg. Because the top of boss 2 is sealed for horizontal fire hole 14 hides in fire lid body 1 completely, on the one hand can open the air door big, make the one-time air volume that gets into through-hole 141 and horizontal fire hole 14 increase simultaneously the speed grow, thereby can more be with the secondary air entrainment get into horizontal fire hole 14, can directly strike with the top of boss 2 after gas, one-time air and secondary air mix into the gas mixture, improved the misce bene of gas and air in the gas mixture, reduced the velocity of flow simultaneously again, improved steady flame performance. If the angle is too large, the area where the mixture gas collides with the boss 2 is likely to be too small, and if the angle is too small, the path of the primary air amount entering the through hole 141 and the lateral ignition hole 14 is likely to be too long, which is unfavorable for entrainment of secondary air. The angle of the acute angle α in this embodiment is preferably 40 °.
Because the transverse ignition hole 14 is hidden in the fire cover body 1, the anti-blocking performance of the ignition hole can be improved, but the problem of insufficient combustion caused by the reduced air quantity of the transverse ignition hole 14 can be solved, and therefore, a notch 21 is formed on the vertical end surface of the boss 2 at the lower part of the opening 143 corresponding to the inner side of the transverse ignition hole 14. The notch 21 allows secondary air to enter the transverse ignition hole 14, and the part 22 at the upper edge of the notch 21 gradually inclines outwards and upwards along the radial direction of the fire cover body 1, so that overflow can be prevented from entering the transverse ignition hole 14 through the inner opening of the transverse ignition hole 14, and secondary air is supplemented to the transverse ignition hole 14 through the notch 21, so that air supplement in the transverse ignition hole 14 is improved, combustion in the transverse ignition hole 14 is stabilized, and fire transfer performance is improved. Preferably, the transverse pilot hole 14 is inclined gradually upwards from its inner opening 143 to its outer opening 142. The inclined design of the transverse ignition holes 14 can strengthen the suction effect on the outside air and improve the air supply speed; on the other hand, the inclined design of the transverse ignition holes 14 has a directional flow guiding effect on secondary air, ensures that the secondary air passes through the fire outlet holes of the inner ring fire cover right opposite to the secondary air after passing through the gas mixing chamber, reduces the supply resistance of the secondary air to the inner ring flame, and ensures that the secondary air is supplied more rapidly; at the same time, the overflow liquid entering the lateral ignition portion can be prevented from entering the through hole 141.
In addition, since the lateral fire hole 14 is hidden in the fire cover body 1 to improve the anti-clogging performance of the fire hole, it is necessary to avoid the overflow from entering the lateral fire hole 14 as much as possible, for this reason, the top of the boss 2 is concavely formed with a groove 23 for guiding the overflow, and at the same time, in order to guide the overflow flowing down from the groove 23 to flow out along the inner annular wall 11 of the fire cover body 1, the groove 23 includes a base 111 integrally connected with the peripheral wall of the inner annular wall 11 and a free portion 112 extending radially from the base 111 toward the center of the fire cover body 1, the groove 23 is gradually inclined downward from the free portion 112 to the base 111 thereof, and the junction of the base 111 and the inner annular wall 11 is further provided with a shrinkage opening 231, and the junction of the outer walls of the both sides of the boss 2 and the inner annular wall 11 is further provided with an arc-shaped guide groove 232 connected with the shrinkage opening 231, the arc-shaped guide groove 232 includes a first end 2311 near the shrinkage opening 231 and a second end 2312 far from the shrinkage opening 231, in order to better guide the overflow.
In addition, after the gas, primary air and secondary air are mixed into the mixed gas, the mixed gas can directly collide with the top of the boss 2, the mixed gas can flow out from the inner side opening of the transverse ignition hole 14 after turning through the part 22 at the upper edge, so that the air flow speed of the mixed gas flowing out of the transverse ignition hole 14 is effectively reduced, the gas at the transverse ignition hole 14 is not easy to leave flame during combustion, and the ignition of the combustor is more stable. Meanwhile, in order to prevent the overflow flowing down from the arc-shaped guide groove 232 from entering the inner opening of the transverse fire guiding hole 14 through the bottom wall 24 of the boss 2, the lowest point of the bottom wall 24 of the boss 2 is located at a position higher than the highest point of the second end of the arc-shaped guide groove 232, and the bottom wall 24 of the boss 2 is adjacent to the inner edge 110 of the fire cover body 1 and has a certain interval d of 0.8mm less than or equal to d less than or equal to 1mm, in the embodiment, d is 0.9mm, the interval between the two is capable of shortening the fire transmission distance of the whole transverse fire guiding hole 14, meanwhile, a notch 21 is formed on the vertical end surface of the boss 2 at the lower part of the inner opening 143 of the corresponding transverse fire guiding hole 14, the notch 21 is used for allowing secondary air to enter the transverse fire guiding hole 14, air supply in the transverse fire guiding hole 14 is improved, combustion in the transverse fire guiding hole 14 is stabilized, and fire transmission performance is improved.
Therefore, the burner fire cover structure of the gas cooker optimally designs the structure of the hidden transverse ignition hole 14, and can effectively prevent the transverse ignition hole 14 from being blocked on the basis of improving the fire transmission performance.
