Description
Affiliated technical field
The utility model relates to the improvement of household gas utensils, especially the improvement to embedded infrared line gas kitchen ranges ignition system.
Background technology
In recent years, built-in type cooker, because of its plurality of advantages such as succinct, high-grade, attractive in appearance, easy to clean, is more and more subject to consumer's selection and accreditation, and has replaced table type kitchen range to become the main product in market.And that embedded infrared line gas kitchen ranges has more in performance is energy-efficient, environment protection health, the superiority such as safe and reliable, sells well gradually and be promoted universal on market.As everyone knows, because the burner of embedded infrared line gas kitchen ranges adopts fully premixed combustion system, its required air that burns all relies on the energy of combustion gas to suck and carries out whole premixs, if it is more difficult directly to light main ignition combustor with electric spark under larger primary air ratio, easily produce detonation or light a fire unsuccessfully, generally design independently the start-up burner structure main ignition combustor that ignites.And for good looking appearance and the structural requirement of embedded infrared line gas kitchen ranges, most of start-up burners are general adopts following several version: start-up burner is arranged on main ignition combustor bottom and takes necessarily for vertical angle, arrives main fiery combustion front by the baffle directs ignition flame of main ignition combustor mesoporous channels; Start-up burner is vertically mounted on main ignition combustor mesoporous channels, and start-up burner forms ignition flame and then the main ignition combustor that ignites.But this type of ignition structure and working method are deposited defect in the following areas on the market:
(1) start-up burner is installed in bottom or the center of burner, in the time that ignition flame meets obstructions or tempering occurs, in the time that ignition point can not ignite main ignition combustor, ignition flame will cause burner bottom, easily burn out the internal wirings such as feedback pin, affect product reliability and have certain potential safety hazard.
(2) start-up burner flame emission direction is mutually vertical with main fiery combustion front; ignition flame need to overcome the structural drag such as baffle plate, Wen Yangaihuo center over cap and be passed to combustion front; when pipe network gaseous-pressure is lower, easily occur that ignition flame cannot overcome resistance and arrive main fiery combustion front.When pipe network gaseous-pressure is higher, the flue gas that the air in central passage is produced by ignition flame is drained rapidly, lacks the transmission of oxygen restriction flame in passage.
(3) start-up burner fixture structure complexity, while being independently installed on burner bottom or center, be difficult for ensureing with the relative position of main ignition combustor, when the reliability of installing and accuracy are poor, easily there is the burning velocity of ignition flame and the spouting velocity difference over balance point of gaseous mixture, and then produce ignition flame tempering or from flame phenomenon, and cannot overcome structural drag and cause lighting a fire unsuccessful.
(4) adopt end igniting or mesopore sparking mode straight up, be subject to the impact of infrared burner bulkiness, the general employing of gas conduct pipe that start-up burner connects and the fixed form of kitchen range drain pan, used the easy oxide etch of gas conduct pipe for a long time, has air-tightness potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is, for the deficiency of existing embedded infrared line kitchen range ignition structure and working method, to provide a kind of igniter that is fixed on infrared burner, to ensure ignition success rate.
The utility model adopts following technical scheme to realize:
An igniter for infrared ray gas range, it has igniting distributor (1), porcelain Needle shield (2), flame inductive needle (3), ignition electrode (4), gas mixing pipe (5), igniting copper pipe (6), fixed head (7).It is characterized in that described igniting distributor (1) is fixed on the central duct of infrared burner (8), its top is provided with the protective cover that is enough to protect ignition electrode (4) entirety and flame inductive needle (3) end.
The fire hole of described igniting distributor (1) flushes or a little more than main fiery combustion front, contributes to improve the transmission of ignition success rate and ignition flame, and stops the potential safety hazard that ignition flame causes to kitchen range internal delivery.
Described igniting distributor (1) can be set to single row or multiple rows fire hole.
Described igniting distributor (1) surface is provided with the passage (9) with infrared burner (8) up/down perforation, and passage can be arranged to single or multiple circles, the difformity such as square, trapezoidal according to the difference of structure.
Described porcelain Needle shield (2) can take different modes to be fixed in igniting distributor (1), or described porcelain Needle shield (2) can be one-body molded with igniting distributor (1), can effectively prevent that greasy dirt from dropping onto on flame inductive needle (3) and ignition electrode (4).
Described gas mixing pipe (5) takes fixed head (7) to be installed in infrared burner (8) central passage, coordinates with gas mixing pipe (5) upper end in air ejection hole the effect that reaches injection primary air and carry Air-fuel mixing gas with igniting distributor (1).
It is upper that described igniting copper pipe (6) takes flange to be connected to fixed head (7), and it does not contact with kitchen range housing, effectively reduces or stop to use for a long time copper pipe (6) oxide etch that causes lighting a fire of drain pan contamination.
The utility model has the advantage of: 1, contribute to improve ignition success rate and arrive ignition flame spread speed.2, can prevent that ignition electrode (4) and flame inductive needle (3) end are by pollutions such as water stain, greasy dirts.3, can effectively reduce or the oxidized corrosion of copper pipe (6) of stopping to light a fire, thereby ensure safety in utilization.4, can ensure the assembly reliability of igniter and main ignition combustor, and then improve ignition success rate.
