S3, when burner combustion, described control device is the more whether completing combustion of the amount ratio of the temperature of temperature sensor and used combustion gas, if imperfect combustion execution in step S5 then, if completing combustion then shows combustion power and stove fire temperature.
S4, when burner combustion, whether the result that the temperature of the continuous detected temperatures sensor of control device and flame ion sensor detect normal, if arbitrary undesired then execution in step S5.
S5, control device send signal and go to cut off combustion gas.
Implement the safety device that igniting, extinguishing of the present invention cuts off combustion gas, have following beneficial effect:
The safety device that described igniting, extinguishing of the present invention cuts off combustion gas comprises that the detection burner combustion produces the flame ion sensor of flame ion, is the igniter of burner igniting, the temperature sensor and the control device of the described burner combustion temperature of detection; Described control device is provided with IC, described control device for temperature that described temperature sensor is detected and the desired temperature in the described IC relatively and work as temperature that described temperature sensor detects and the desired temperature in the described IC and exceed preset range and just send the control device that signal removes to control fuel gas shutoff.Such structure can determine that burner whether in burning, will not avoid the generation of accident in very short time internal cutting off combustion gas if do not burn by the difference of C.T.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation that igniting, extinguishing of the present invention cuts off safety device first embodiment of combustion gas.
The specific embodiment
As shown in Figure 1, cut off among first embodiment of safety device of combustion gas at igniting, extinguishing of the present invention, the safety device that described igniting, extinguishing cuts off combustion gas comprises the flame ion sensor that detects burner combustion and produce flame ion, is the igniter of burner igniting, the temperature sensor and the control device of the described burner combustion temperature of detection; Described control device is provided with IC, described control device for temperature that described temperature sensor is detected and the desired temperature in the described IC relatively and work as temperature that described temperature sensor detects and the desired temperature in the described IC and exceed preset range and just send the control device that signal removes to control fuel gas shutoff.
Wherein, the flame ion sensor is the circular shaft shown in the Reference numeral 50, comprises the upper and lower, and the outside of its underpart is provided with pottery 30, and the effect of pottery 30 is heat insulation.Offer dead slot 20 in the inside, flame ion sensor 50 bottoms, dead slot 20 the insides are equipped with the temperature sensor 42 of the temperature of measuring burner combustion.Temperature sensor 42 is arranged at the upper end of 20 li of dead slots, be arranged on the outer Reference numeral 41,40 of dead slot and be two lead-in wires of temperature sensor, Reference numeral 44 is the lead-in wire of flame ion sensor 50, Reference numeral 41,40,44 is connected with the control device (not shown), and the control device the inside is provided with IC.
Described temperature sensor 42 can also be arranged at the side of described flame ion sensor 50, and described temperature sensor 42, flame ion sensor 50 are arranged in the described burner.
Certainly, we also can be placed on temperature sensor 42 outside of flame ion sensor 50, and it is more convenient when mounted more accurate with result that measure just to be placed on the inside.
The safety device using method that igniting, extinguishing of the present invention cuts off combustion gas comprises the steps:
