Fire cover for gas stove
Technical Field
The invention relates to a burner of a gas cooker, in particular to a fire cover for a gas cooker.
Background
At present, most of traditional burner fire covers sold in the market are milled through a groove, namely a fire ignition groove is milled through the top of the fire cover body, and the burner fire cover is easy to deform due to the fact that the fire cover body is disconnected at the fire ignition groove, so that the fire ignition effect is influenced. For example, a similar fire transfer structure is disclosed in the chinese patent invention "gas furnace head with fire transfer device and flameout protection function" with patent No. 201220464214.0 (publication No. CN202813375U), wherein an outer ring fire spraying ring is provided with a plurality of outer ring fire spraying holes, and an outer ring fire transfer device is further provided on the outer ring fire spraying right, the outer ring fire transfer device is composed of a boss installed on the inner side wall of the outer ring fire spraying ring, an outer ring fire transfer hole and an outer ring fire transfer groove provided on the boss and the outer ring fire spraying ring, the outer ring fire transfer hole is communicated with the outer ring fire transfer groove, the outer ring fire transfer hole and the outer ring fire transfer groove are communicated with one outer ring fire spraying hole, so as to realize rapid fire transfer; the fire transfer groove of the fire transfer structure is open, the fire transfer groove is linear, namely the fire transfer groove is exposed on the surface of the outer ring fire cover, the design of the design has a benefit that the secondary air in the fire transfer groove is sufficiently supplemented, the open fire transfer groove can ensure the supplement of the secondary air during the flame combustion in the fire transfer groove, the flame combustion and the fire transfer are facilitated, and the open fire transfer groove has the characteristic of quick fire transfer, but has two disadvantages, the first open fire transfer groove and the open fire transfer groove are easy to cause the blockage of the fire transfer groove, namely soup flowing from the bottom of a pan is easy to flow into the fire transfer groove, the fire transfer performance is influenced after the blockage, and the main reason for the blockage maintenance of the current fire transfer groove is also included; secondly, the open fire transmission groove has high requirements on the air door of the stove, and after the air door is opened to a large extent, too much air can cause too high air speed, so that flame is separated or flame is released during combustion. For this reason, further improvements in the fire transfer slots of burner fire covers are desired.
Disclosure of Invention
The invention aims to solve the first technical problem of providing a fire cover for a gas stove, which can reduce the gas speed at a fire ignition part.
The second technical problem to be solved by the invention is to provide the fire cover for the gas stove, which can improve the fire transfer efficiency of the ignition part.
The technical scheme adopted by the invention for solving the technical problems is that the fire cover for the gas stove comprises a fire cover body, wherein an annular top wall of the fire cover body, an inner annular wall and an outer annular wall which vertically or obliquely extend downwards from the inner side edge and the outer side edge of the annular top wall form a gas mixing cavity, the upper surface of the fire cover body radially and outwards extends from the inner annular wall to the outer annular wall towards the center of the fire cover body to form a fire transfer chamber, and the top wall of the fire transfer chamber is provided with a fire ignition groove.
Furthermore, the ignition groove is provided with a boss which is relatively isolated from the ignition groove, a gap is arranged between the bottom of the boss and the ignition groove, and at least one pair of through holes penetrate through the boss. The gas that does not flow out with the through-hole that the boss link up then flows through the interval between boss and the ignition groove to effectively reduce the gas speed that the through-hole flows out.
In order to ensure that the fuel gas flowing out of the through hole communicated with the boss can flow out of the inner side opening and the outer side opening on the two sides of the ignition groove, the top end of the boss is provided with a flow guide inclined plane which gradually inclines upwards from bottom to top.
In order to avoid that the through holes communicated with the gas mixing chamber are all communicated with the boss, no gas flows out from the space between the boss and the ignition groove, so that the phenomenon of fire transfer blocking possibly occurs, and the bottom of the ignition groove is provided with a gas inlet hole communicated with the gas mixing chamber on at least one side of the boss. The arrangement of the air inlet hole can ensure smooth fire transfer.
In order to prevent the gas outlet speed of the gas inlet hole from being too high, at least one side of the top opening of the ignition slot extends with a convex edge along the circumferential direction and corresponding to the position of the gas inlet hole, and the center line of the gas inlet hole is perpendicular to or intersected with the convex edge. The setting up of this chimb makes the gas that gets into the gas pocket can be with the chimb looks offset to make gas and air mix can be directly after the gas mixture with the chimb striking, improved gas, primary air, secondary air's mixing uniformity in the gas mixture, reduced the velocity of flow simultaneously again, improved the flame stabilization performance.
Further, the convex edge is connected with the flow guide inclined plane. In order to ensure that the fuel gas flowing out through the through hole communicated with the lug boss is uniformly distributed along the ignition groove from inside to outside.
Furthermore, the ignition groove is provided with an inner side opening facing the center of the fire cover body, and the fire transfer chamber is provided with an air outlet communicated with the air mixing chamber under the inner side opening. The air outlet hole can supplement air to the inner side of the ignition groove so as to avoid unsmooth fire transfer caused by insufficient air at the starting position of the ignition groove.
Preferably, the air outlet is inclined inwards and gradually approaches the inner side port from the air inlet end communicated with the air mixing chamber to the air outlet end communicated with the fire transfer chamber.
Furthermore, the outer ring wall is provided with at least two fire outlets communicated with the gas mixing cavity along the circumferential direction.
In order to stabilize the flame and fire outlet, at least two flame stabilizing holes communicated with the gas mixing cavity are formed in the outer ring wall below the fire outlet along the circumferential direction.
In order to stabilize the pressure and flame stabilizing holes, grooves which are intersected with the flame stabilizing holes and/or the flame outlet holes are formed in the outer ring wall below the flame outlet holes along the circumferential direction. The pressure stabilizing part formed by the groove can obviously improve the combustion efficiency of the gas stove while stabilizing flame and holding the flame stabilizing hole and the fire outlet hole.
Preferably, the center lines of each pair of through holes intersect at an angle α, the angle α is obtuse, the angle α is obtuse to further increase the strength of the through holes in each pair, and the angle α may be acute.
Compared with the prior art, the invention has the advantages that through the through holes communicated with the gas mixing chamber are arranged in the ignition slot, the central lines of the through holes are intersected, and the gas flowing out from the through holes are oppositely flushed, so that the mixing uniformity of the gas and the air in the ignition slot is improved, the flow rate is reduced, and the flame stabilizing performance is improved, thereby solving the problem that the ignition slot is an open type communicated with the outside, the flame transfer blocking phenomenon caused by the overhigh speed of the gas is easily generated, playing a good flame stabilizing role on the flame at the ignition slot, ensuring the secondary air supply of the internal flame transfer slot, namely ensuring the flame combustion in the flame transfer slot, and simultaneously enhancing the applicability of the opening degree of the air door, namely ensuring the flame transfer performance under the condition of larger opening degree of the air door.
