Description
Technical field
The utility model relates to a kind of gas-cooker, relates to the improvement technology of ignition function and flame inducing function on the gas-cooker in particular.
Technical background
Since 2002; all embedded gas-cookers of national standard mandatory provision must have flame-out safety guard; the now normal gas combustion range flameout safety guard that adopts has two classes: a class is to survey the thermoelectric (al) type protective device (being commonly called as the thermocouple mode) of flame temperature, another kind of flame induction mode based on direct detection flame (being commonly called as the ion induction mode).Because of the reliability of ion induction mode and security and life-span will be higher than thermoelectric (al) type, so the safety guard that adopts on gas-cooker is many based on the ion induction mode.But the igniting of the ion induction type safety guard that adopts on gas-cooker at present and flame sensing part are separately installed with each one of igniting pin and flame inductive needle, to satisfy the required requirement of igniting and flame induction respectively.This gas-cooker is realized igniting and flame inducing function respectively because of needing igniting pin and inductive needle, make the structure of kitchen range become complicated, and for many more also easy the breaking down more just of electrical structure components and parts, the fault rate and the maintenance rate that can cause kitchen range improve, and the while also exists certain potential safety hazard to the use of gas-cooker.
The utility model content
Problem to be solved in the utility model is, overcome the shortcoming and defect of existing gas-cooker, a kind of single needle gas-cooker is provided, this gas-cooker realizes that on the conducting metal pin composite members of a tape insulation layer igniting and flame responds to dual-use function, makes that the gas-cooker structure is simpler, reliability and security be higher.
The utility model can be achieved through the following technical solutions its purpose.
A kind of gas-cooker, comprise plug valve, burner, electronic control system and magnetic valve that is electrically connected with control system and power switch, magnetic valve is arranged on the air inlet pipe, power switch is installed on the plug valve, it is characterized in that: the described burner outside or inboard installing have the igniting inductive needle of igniting and flame induction dual-use function, and the igniting inductive needle is electrically connected with control system.
Described igniting inductive needle is the conducting metal pin composite members of single head formula tape insulation layer, or the conducting metal pin composite members of bullhead tape insulation layer.
Described igniting inductive needle is arranged on around the burner fire hole in the 10mm scope, is fixed on gas-cooker base or the burner.The utility model has just solved igniting and the required requirement of flame induction because of only having adopted a heatproof metal needle, makes that the structure of kitchen range is simpler, and electric property is more stable, reliable, and outward appearance is more beautiful.
For security and the reliability that improves gas-cooker, and make the structure of gas-cooker more succinct, gas-cooker of the present utility model redesigns electronic control system.
Electronic control system of the present utility model mainly comprises high-voltage pulse drive circuit and the flame sensor circuit that connects the igniting inductive needle, connects the driving circuit for electromagnetic valve of magnetic valve, and the switch interface circuit that connects power switch.
After described igniting inductive needle is lighted combustion gas, produce little current signal and feed back in the electronic control system, flame sensor circuit output high level signal to driving circuit for electromagnetic valve to keep the opening of magnetic valve; Perhaps, after combustion gas was extinguished, igniting lost little current signal on the inductive needle, flame sensor circuit output low level signal to driving circuit for electromagnetic valve with closed electromagnetic valve.
That is to say, electronic control system starts according to the break-make of power switch or cuts off ignition drive circuit and flame sensor circuit and driving circuit for electromagnetic valve, and has or not according to the flare up fire of sensing on the igniting inductive needle and to control driving circuit for electromagnetic valve and be in the state of opening or closing by magnetic valve.
The utility model has following substantive distinguishing features and progress with respect to prior art.
1. provide a kind of ignition function and flame inducing function have been integrated into the gas-cooker of realizing on the igniting inductive needle, made the structure of gas-cooker integral body more simple, attractive in appearance.
2. reduce the fault rate of kitchen range electrical safety performances, improved security, reliability and the stability of gas-cooker.

The specific embodiment
Below in conjunction with accompanying drawing single needle gas-cooker of the present utility model is described further.
Gas-cooker as shown in Figure 1, 2, be fixed with two burners 3, air inlet pipe 4, electronic control system 6, plug valve 7 on the base 1 and be fixed on power switch 62, power supply 8 on the plug valve 7, be fixed on magnetic valve 61 on the air inlet pipe, be fixed with igniting inductive needle 63 in 10mm scope around the gas apparatus fire hole, be connected with between plug valve 7 and burner 3 and connect tracheae 5, panel 2 shown in Figure 1 is installed on the base 1.
This gas-cooker can adopt the bullhead igniting inductive needle 63B as the single head formula of Fig. 3 igniting inductive needle 63A or Fig. 4, and they are made up of metal needle, insulating barrier and connecting line respectively, another connecting line of inductive needle 63B bottom shell of meeting sb. at the airport.
Electrical connection diagram as shown in Figure 5, electronic control system 6 connects the combustion gas break-make that magnetic valve 61 is used to control whole gas-cooker, electronic control system 6 is connected the break-make that is used to control electronic control system 6 power supplys with power switch 62, and electronic control system 6 connects igniting inductive needle 63 and is used for igniting and induction flame.
Electrical schematic diagram as shown in Figure 6, IC1, IC2, R1, R2, R3, R4, R5, R6, R8, R9, R12, R13, R14, R15, R16, C1, C2, C3, C4, C7, D1, D2, D3, D4, D8 and B1, B2, T1, Q1, Q2, Q3 form high-tension ignition and flame sensor circuit, R10, R11, C6, D5, D6, D7 and Q4, Q5 form driving circuit for electromagnetic valve, K1 is a power switch, and C5 and R7 form the clear circuit of IC1.
