Description
Technical field
The present invention relates to a kind of for using the igniter in the gas burner assemblies of cooking apparatus.The present invention is especially
It is related to a kind of gas burner assemblies with built-in ignitor device.
Background technology
Using inflammable gas（Such as liquefied petroleum gas (LPG)）Gas cooking apparatus in, usually utilize pilot spark
Plug（Also referred to as igniter）To light the gas flowed out from the gas vent of gas burner assemblies.Igniter is generally included by porcelain
Manufactured high temperature insulation shell, the electrode for generating pilot spark and the cable for high-voltage electricity to be supplied to the electrode.
Igniter is usually built at the position close to gas vent in gas burner assemblies.Electrode is usually prominent from the tip of shell
Go out.However, electrode is most important for gas ignition performance relative to the position of gas vent.If electrode is insufficient close
Gas vent then the firing delay of gas or falls flat.In the case of delay, especially in high capacity gas burner group
In part, gas starts the rapid aggregation near gas vent and leads to high-explosive when it is finally lighted.It is such quick-fried
The fried safety and health to user constitutes dangerous.Therefore, the appropriate installation utmost importance of igniter.
03/058126 A1 of WO disclose a kind of cooker.The cooker includes one or more burner assemblies.Often
A burner assembly includes the burner chassis with gas access, the burner cap with flame export port and has
The spark plug of stopper.Recess installs spark plug in flame export near ports are formed to burner chassis.It is installing
When burner assembly, is inserted the sparkplug into first into the through-hole of connector and be subsequently fitted in the recess on burner chassis.
Burner cap is placed on burner chassis.
The shortcomings that above-mentioned cooker, is that utilizing for connection assist increases manufacturing step and lead to extra cost.It is logical
Often, when by part assembled with one another number increase when, igniter suitably installs the risk being compromised during assembly
Inevitably increase.Therefore, in the case of misalignment, ignition performance can be easy to degrade.
Invention content
It is an object of the present invention to provide a kind of igniters for being used to use in gas burner assemblies and one kind having institute
The cooking apparatus for stating igniter overcomes the disadvantages mentioned above of the prior art, and it realizes the simple and reliable installation of igniter
And improved ignition performance.
This target is by igniter according to the present invention, gas burner assemblies according to the present invention and according to this hair
Bright cooking apparatus is realized.
For the igniter of the present invention suitable for use gas burner assemblies, the gas burner assemblies include burning
Device base portion, the burner base include the through-hole for being inserted into igniter.The gas burner assemblies of the present invention include with spiral shell
Line mode can mount to the burner head of burner base.The burner head include be the radially projecting of circular shape
Lower edge and the radially projecting top edge for being also circular shape.The outer diameter of top edge is more than the outer diameter of lower edge.The present invention's
There is igniter flange of taking one's seat, lower surface to be tilted relative to the longitudinal direction of the shell of igniter.It is inserted into when igniter
In state when in through-hole and when burner head is threadably installed to burner base, flange of taking one's seat is tilted with it
Flush against the upper horizontal surface of burner base, the upper periphery of shell abuts top edge, and flange portion of taking one's seat for lower surface
Ground is interposed between the lower edge of burner head and the upper surface of burner base.
In embodiment, flange of taking one's seat has lateral flat part, and when shell is inserted into through-hole, the transverse direction is flat
Part abuts the flat wall part of burner base.Therefore, when burner head is threadably installed to burner base,
It can be easy to prevent igniter from rotating.
Through the invention, it has eliminated to assisting connecting element（Such as clamping piece, insertion piece or the like）Needs.And
And by inclined lower surface and top edge, can correctly be determined when installing igniter pre- between electrode and burner head
Fixed constant distance, and therefore, it can permenant guarantee ignition performance.In particular, when burner head is closely screwed to burning
When in device base portion to take one's seat flange can caused by any deformation（Such as it squeezes）Do not lead to the misalignment of shell, because shell
Upper periphery and top edge keep rigid contact and ensure optimum spark gap for igniting.Therefore, eliminated igniting delay and
Both failures, and obtained appropriate operating condition.
