Description
The utility model relates to the igniter that a kind of gas range, gas heater are used.
Common ignition can send the electrion spark when starting gas range, coal gas is lighted.Yet, gas fire because of wind, pot in, after soup overflows and extinguish, can not light automatically, must rekindle by the people.
The purpose of this utility model is the ignition that proposes the automatic resume combustion of a kind of energy.The flame of gas range, gas heater etc. rekindles coal gas overflowing etc. former because of wind or soup thereby can sending the electrion spark automatically during unexpected extinguishing.
This automatic resume combustion ignition comprises an inductance type electro coupled oscillator and a controllable silicon impulse generator, electro coupled oscillator comprises generator triode and oscillation transformer, the output winding of oscillation transformer is received the input of controllable silicon impulse generator, the grounded emitter of generator triode, colelctor electrode with receive power cathode after the oscillator coil of oscillation transformer is contacted mutually, it also comprises a thermoswitch, the feedback coil of oscillation transformer with receive between the base stage of power cathode and generator triode after thermoswitch is contacted mutually.
When this automatic resume combustion ignition uses thermoswitch is installed near the burner of gas range or gas heater.Connect power supply, after coal gas was lighted, thermoswitch disconnected because of being heated, the generator triode open base, and triode is not worked, the ignition no-output.When gas burner overflows because of wind, soup or other accidental cause when extinguishing, thermoswitch Yin Wendu reduces and connects generator triode work, produce oscillator signal, be transferred to the controllable silicon impulse generator through oscillation transformer, make it produce the electrion spark, coal gas is rekindled.
Accompanying drawing 1 is the basic structure schematic diagram of this automatic resume combustion ignition;
Accompanying drawing 2 is the another kind of structure chart of this igniter;
Accompanying drawing 3 is a kind of structure chart of thermoswitch;
Accompanying drawing 4 is the structure chart of another kind of thermoswitch.
As shown in Figure 1, (3) be the inductance type electro coupled oscillator, comprise generator triode (12) and oscillation transformer (5), the output winding of oscillation transformer (6) is received the input of controllable silicon impulse generator (7), the grounded emitter of generator triode (12), colelctor electrode with receive power cathode after the oscillator coil (13) of oscillation transformer (5) is contacted mutually, (2) be thermoswitch, it be connected between the base stage of power cathode and generator triode (12) after the feedback coil (4) of oscillation transformer (5) is contacted mutually.(11) be battery, (1) is power switch.After power switch closes, if coal gas is unignited, thermoswitch (2) is in closure state, the oscillating voltage that oscillator produces outputs to the controllable silicon pulse by output winding (6) and sends out device (7) after oscillation transformer (5) boosts, be rectified into direct current through commutation diode (14), to electric capacity (17), (24) charging.Electric capacity (17) charging interval is longer, when voltage is charged to diac (8) conducting when enough high, trigger controllable silicon (9) conducting, electric capacity (24) is exported an electrion spark by pulse of controllable silicon (8) discharge generation after step-up transformer (10) boosts.Charging once more goes round and begins again like this behind the charge discharge on electric capacity (17) and (24), constantly exports the electrion spark, until coal gas is lighted.After coal gas was lighted, thermoswitch (2) was subjected to thermal cutoff, oscillating circuit failure of oscillation, no high tension spark output.As long as power switch (1) is in closure state, igniter just is in the preparation state always, in case gas burner extinguishes thermoswitch closure, i.e. output igniting high-voltage pulse.Resistance among the figure (25) is the operating point that is used for determining triode (12).
As shown in Figure 2, this automatic resume combustion ignition can also comprise a control triode (16), receive between the base stage of power cathode and generator triode (12) behind feedback coil (4) polyphone of colelctor electrode, emitter stage and the oscillation transformer of this control triode, thermoswitch (2) is received between the base stage and power cathode of control triode, and the base stage of control triode links to each other with ground by a resistance (15) again.The service behaviour of the thermoswitch in this ignition should be a closure when being heated, and disconnects during cooling, is open in usual.When flame ignition, thermoswitch is heated and closed, and the base stage of control triode (16) is by feedback coil (4) and emitter stage short circuit, and the control triode ends, generator triode failure of oscillation, dead-beat output.When fray-out of flame, thermoswitch disconnects, and the base stage of input triode (16) and emitter stage disconnect, the conducting of control triode, generator triode (12) vibration, igniter output high-voltage pulse ignition voltage.
As shown in Figure 3, the thermoswitch of this automatic resume combustion ignition can be made with bimetal leaf, the shell (18) and the central electrode (19) that comprise a metal, central electrode and shell fix by insulator (22), and mutual insulating, at least one window (20) is arranged on the shell, be welded with a bimetal leaf (21) in the window.When the free end of bimetal leaf contacts with central electrode, the thermoswitch closure.When the free end of bimetal leaf and central electrode broke away from, thermoswitch disconnected.Change the different coefficient of expansion faces of bimetal leaf towards, thermoswitch is become be heated closure or be subjected to the form of thermal cutoff.Structure shown in the figure is the form that disconnects when being heated, i.e. normally closed type.
As shown in Figure 4, thermoswitch also can be made on two relative sides of the metal shell (18) at it respectively a window (20), weldering one bimetal leaf (21) in each window can make the relative both sides of central electrode be subjected to the pressure of bimetal leaf simultaneously like this, and is stressed more even.Can also open several windows (23) on the metal shell in addition, to accelerate the speed of heat radiation, to improve the sensitivity of thermoswitch.Thermoswitch shown in the figure is a structure open in usual.
