Abstract
The utility model relates to an accidental flameout protector with an electronic impulse automatic igniter for household gas ranges. Electronic pulse automatic ignition is adopted, an electromagnetic valve is used for controlling a gas passage, and an independent controllable power switch is adopted to control the ignition, the extinguishment and the accidental flameout protection monitoring of a cooking range. A flame sensing needle is arranged at an inner ring of a burner and forms a flame sensing part together with the burner, an electronic control circuit is utilized to monitor the burning state of the cooking range, and if accidental flameout occurs, the electromagnetic valve is controlled to cut gas immediately to prevent the leakage of the gas. The utility model has the advantages of sensitive response and no inertness, and simultaneously, the corresponding mechanical structures of cooking ranges are simplified to make the work of cooking ranges safer.
Description
The utility model relates to a kind of pulse automatically igniting and protector of accident extinguishing, and the electronic impulse that particularly relates to a kind of domestic gas (coal gas, liquefied petroleum gas, natural gas, biogas) kitchen range is unexpected flame-out protective device in igniting and the combustion process automatically.
Existing thermocouple---electromagnetic type gas kitchen ranges protector of accident extinguishing; include gas electromagnetic valve of a temperature-difference thermoelectric even summation; utilize thermoelectricity on a rare occasion to hold and be heated back generation electromotive force; " the temperature-difference thermoelectric effect " that cooling back electromotive force disappears controlled the open and close of gas electromagnetic valve, reaches the purpose of accident extinguishing protection.But existing thermocouple---there is following deficiency in the electromagnetic type protector of accident extinguishing:
1, because thermocouple has the electromotive force of bigger thermal inertia, its output can not light and moment of putting out produces immediately or disappears at kitchen range, response lag, make the adhesive and the dispose procedure of magnetic valve produce delay, so after accident extinguishing occurring, magnetic valve can not in time cut out, still have gas leakage in a period of time.
2, because the electromotive force that thermocouple produces is less, deficiency is so that magnetic valve nature adhesive and must cause the corresponding mechanical part complex structure of protective device by means of external force, the heavier and fault rate height in use of feel during manipulation.
The purpose of this utility model provides a kind of combustion position to gas kitchen ranges and is quick on the draw; the gas kitchen ranges protector of accident extinguishing that control is reliable and the simple charged subpulse of frame for movement is lighted a fire automatically; it can not only be when kitchen range be opened; the output high-voltage pulse produces electric spark and lights kitchen range; and reliable rapidly in to the monitor procedure of kitchen range combustion position, thereby its gas electromagnetic valve need not rely on external force to make corresponding frame for movement more simple in opening process.
The purpose of this utility model is achieved in that whole device by electronic control circuit, and spray point, flame sensing part, magnetic valve and gas control valve are formed.Electronic control circuit is made up of power supply, power switch, power supply indicator, delay circuit, firing circuit, flame inductive control circuit and solenoid valve control circuit.Can control lighting of kitchen range by power switch, extinguish and the accident extinguishing protection.Power switch is installed on the kitchen range control panel; The flame sensing part is that ring is provided with the flame inductive needle as an electrode in burner, and will encircle the bottom in the burner as another electroplax, utilizes " thermoelectronic effect " that the combustion position of burner is sampled, for electronic control circuit supplies detection signal; Magnetic valve is an executing agency, and it is controlled by electronic control circuit; Can regulate the size of firepower in the kitchen range combustion process by gas control valve, have suffered the control procedure divided combustion, extinguish, three kinds of situations of accident extinguishing are respectively described below:
1, the burning control procedure: connect power switch-→ power supply indicator is bright-→ delay circuit picks up counting-→ firing circuit connects, the output firing pulse and by spray point produce discharge spark-→ when connecting with firing circuit, solenoid valve control circuit also connect and control electromagnetic circuit opening of valves output fuel gas-→ fuel gas through gas control valve on burner, lighted by electric spark-→ kitchen range take fire-→ be installed in burner in the flame inductive needle by the ring detect the burning signal-→ the flame inductive needle with detection signal deliver to the flame inductive control circuit-→ the flame inductive control circuit removes to control solenoid valve control circuit according to detected signal, make its opening that still can output current after delay circuit cuts out keeps magnetic valve-→ 2-3 after second delay circuit close-→ firing circuit cuts out-→ the kitchen range normal combustion, the flame inductive control circuit is monitored combustion position by the flame inductive needle.
2, kitchen range extinguish control procedure: the powered-down switch-→ power supply of The whole control circuit is cut off-→ closed electromagnetic valve, cut off combustion gas-→ fray-out of flame on the burner: delay circuit resets in the time of powered-down, for igniting next time is prepared.
3, accident extinguishing control procedure: gas kitchen ranges is in the normal combustion process; be subjected to being arranged on the monitoring of the flame sensing part on ring side in the burner; in case of accident extinguishing-→ the flame inductive needle immediately detected signal is delivered to the flame inductive control circuit-→ the flame inductive control circuit according to detection signal go to control solenoid valve control circuit-→ solenoid valve control circuit cut off immediately the electric current of electromagnetic valve coil-→ closed electromagnetic valve cuts off combustion gas, reaches the purpose of blowout protection.
Owing to adopt such scheme; power switch (igniting, flame-out) separates with gas control valve; the unlatching of magnetic valve does not need by external force; simplify corresponding frame for movement, reduced the fault rate in manufacture difficulty and the use, need not wait for duration of valve opening during igniting; make operation more convenient; and blowout protection circuit reaction agility does not have inertia, the unlatching of magnetic valve and close with the kitchen range combustion position and keep having stopped the leakage of combustion gas fully synchronously.Make kitchen range work safer reliable.
