Description
Technical field
The present invention relates to ring fire covers in gas-cooker field more particularly to a kind of anti-blocking burner.
Background technique
Existing gas burner generally comprises two fire covers of inner and outer rings, offers fire hole in the fire cover, and together with point
The elements such as fiery needle, thermocouple, which are realized, to be generated flame, maintains the functions such as flame.There is bottom pot waters, the bottom of a pan for traditional interior ring fire cover
Long-term greasy dirt inlet point fire hole and the risk for blocking fire hole.Thus existing interior ring fire cover is generally integrally formed with umbrella,
Ignition electrode is protected by the umbrella.Such as application No. is 201010135138.4 (application publication number CN
101832560 A) Chinese invention patent disclose a kind of gas-cooker central flame cap and application and have the burner of the central flame cap,
The central flame cap includes cylinder and the end cap on the cylinder, and the side of the end cap forms the protection for covering ignition electrode
It covers (i.e. umbrella), accordingly, ignition electrode is then located at the protection lower position, plays the role of protection.However, when greasy dirt,
It when water droplet etc. drops to umbrella top surface, can enter in the fire hole below umbrella along wall, and then block fire hole, cause to light a fire
Bad error.
Summary of the invention
The technical problem to be solved by the present invention is to for the prior art and provide it is a kind of can effectively avoid igniting hole plug
Anti-blocking burner in ring fire cover.
The technical scheme of the invention to solve the technical problem is: ring fire cover in a kind of anti-blocking burner, including
The fire cover ontology of tubular and end cap set on the fire cover ontology top, the end cap and fire cover ontology enclose and set to form mixed air cavity, the end
The side of cap is provided with umbrella, offered on the side wall of the fire cover ontology below the umbrella be connected to above-mentioned mixed air cavity go out
Fire hole, which is characterized in that the anti-blocking groove being recessed inwardly is provided on the side wall of the fire cover ontology below the umbrella, this is anti-
The both ends of stifled groove are located at the two sides of umbrella.
Preferably, offering the auxiliary ignition holes being connected to above-mentioned mixed air cavity on the cell wall of the anti-blocking groove.Pass through
Be arranged auxiliary ignition holes, in this way when light a fire hole plug when, auxiliary firing can be carried out by the flame in the auxiliary ignition holes, this
Outside, the flame in auxiliary ignition holes can carry out calcination to the drop dripped from umbrella, realize automatically cleaning, discharge is avoided to block
Anti-blocking groove thoroughly prevents a possibility that liquid overflows into fire hole from anti-blocking groove again.
Preferably, the anti-blocking groove is extended internally by the sidewall horizontal of fire cover ontology, the auxiliary ignition holes
It is provided on the cell wall opposite with the opening of anti-blocking groove.It can smoothly be rested on after the anti-blocking groove of drop inflow so anti-blocking recessed
In slot, and auxiliary ignition holes are arranged on the cell wall opposite with the opening of anti-blocking groove, and auxiliary ignition holes can not only be made to spray
Flame is preferably sprayed from the notch of anti-blocking groove, and is avoided that the drop into anti-blocking groove to auxiliary ignition holes Flame
Burning have an impact.
Further, it is preferable that the duct of the auxiliary ignition holes along anti-blocking groove cell wall horizontal extension, it is auxiliary so as to make
Help the flame direct-injection of fire hole in the notch of anti-blocking groove, so as to improve auxiliary ignition holes ignition success rate, this external enwergy into
The discharge for entering anti-blocking groove carries out direct calcination, and such part discharge has been sprayed by auxiliary ignition holes before not entering anti-blocking groove
Flame calcination removal.
Further, it is preferable that the umbrella is integrated with end cap, and the duct of the auxiliary ignition holes is along anti-blocking groove
Cell wall extend straight down, so as to make auxiliary ignition holes flame direct-injection anti-blocking groove roof, and the anti-blocking groove
Roof is end cap, can be preheated in this way to umbrella by the upward direct-injection flame of auxiliary ignition holes, discharge drops to guarantor
It can evaporate, and then lose flowability because of high temperature when protecting umbrella.
Preferably, the longitudinal section of the anti-blocking groove is square or arc-shaped.
Preferably, the fire hole is provided with the lower section of anti-blocking groove, the lower lip of the notch of the anti-blocking groove is downward
It is recessed and is formed and assist anti-blocking slot, the anti-blocking slot of the auxiliary is opposite with umbrella, and the partial hole of superposed each fire hole
Road is located in the anti-blocking slot of the auxiliary.Anti-blocking slot is assisted by setting, to increase going out for the fire hole for being located at fire cover body upper part
The area of burner, and then surface tension of the liquid at the crater is reduced, prevent discharge from blocking fire hole.
Preferably, the peripheral side of the bottom surface of the umbrella is recessed upwards and is formed the diversion trench of annular.Such discharge
Dropping to when umbrella flow to umbrella bottom surface along wall can be guided in diversion trench, and discharge is avoided to be dripped by the middle part of umbrella bottom surface
It influences to light a fire to ignition electrode.
Preferably, the anti-blocking groove is recessed inwardly by the upper end of fire cover ontology corresponding with umbrella, this
Sample is thoroughly avoided droplets from and is crossed along fire cover body surface by that can flow directly into anti-blocking groove on umbrella along the drop that wall flows down
Anti-blocking groove and flow in fire hole or fire output hole.
Compared with the prior art, the advantages of the present invention are as follows: it is provided with anti-blocking groove on the interior ring fire cover in the present invention, and
And the both ends of the anti-blocking groove are located at the two sides of umbrella, in this way when greasy dirt, water droplet etc. drop to umbrella top surface, and edge
It when the surface of umbrella wall and fire cover ontology flows down, can not flow into fire hole, and flow into anti-blocking groove, effectively avoid liquid
Drop instills fire hole and leads to hole plug of lighting a fire.
