Description of drawings
Fig. 1 is a principle schematic of the present invention.
The specific embodiment
Below through concrete embodiment and combine accompanying drawing that the present invention is described in further detail.
Fig. 1 is a principle schematic of the present invention:
Gas furnace energy-saving safe automaton of the present invention comprises power supply, sampling section, control section and operating part, and sampling section comprises that sensor is connected with sensing controler, and control section is to survey controller, and operating part is igniter and gas electromagnetic valve; Sensor is connected with sensing controler, surveys controller and is connected with the gas electromagnetic valve control circuit with igniter respectively; The output of sensing controler is connected with electronic switch; Electronic switch is connected on the ac power supply loop of control section and operating part.K is a power switch.
Particularly, survey controller and comprise control module, induction type blowout protection module and solenoid valve control circuit, the output of control module is connected with the gas electromagnetic valve control circuit with igniter.The probe of induction type blowout protection module is installed in flame zone, and the input of control module is connected with induction type blowout protection module; Induction type blowout protection module connects the gas electromagnetic valve control circuit through control module.
Particularly, at emergent gauge tap DJ of device ac power supply loop series connection.Emergent gauge tap DJ is the normally closed type switch.The effect of emergent gauge tap DJ is: when kitchen range are also on cooking stove, artificially close gas flame-out after since this moment device power supply operate as normal; Because the effect of induction type blowout protection module; Need restart the igniting program, at this moment, as long as kitchen range are removed; Sensor signals and starts sensing controler and survey controller work, and device control igniting supervisor gets into operate as normal; But, if kitchen range inconvenience is removed, utilize emergent gauge tap DJ that power supply is broken off, can the starting ignition program.
Preferably, said induction type blowout protection module adopts thermocouple flame detecting module, and the probe of thermocouple flame detecting module is installed in the burner combustion chamber.
Preferably, the preferred infrared sensor of described sensor comprises infrared transmitter, infrared remote receiver, and infrared transmitter and infrared remote receiver are installed in the both sides of kitchen range respectively.
Preferably, the control module of surveying controller comprises first delayer, and first delayer is with the ignition signal time-delay 0.1～0.3 second that is as the criterion, and its output connects gas electromagnetic valve control circuit, guarantees fire back gas earlier, prevents that dryness-fire or combustion gas from rushing down earlier.
Preferably; The control module of described detection controller comprises second delayer; The control module of surveying controller comprises second delayer, and second delayer connects induction type blowout protection module, to receive ignition signal 2～3 seconds induction type blowout protection modules of time-delay work that is as the criterion.Receiving delays time behind the ignition signal connected induction type blowout protection module in 2～3 seconds, and induction type blowout protection module is through control module control gas electromagnetic valve control circuit.
2～3 seconds induction type blowout protection modules of delaying time work can be worked earlier by the guarantee point firearm, guarantees normal ignition; Behind gas electromagnetic valve unlatching, the normal ignition; Whether induction type blowout protection module begins to detect can flame normal; If flame is undesired; Induction type blowout protection module is issued the control module of surveying controller with signal, and the control module control gas electromagnetic valve control circuit of surveying controller turn-offs gas electromagnetic valve, and preventing not have fire has gas to leak.
