Further, flame detector is ultraviolet flame detectors 5.
Ultraviolet flame detectors 5 adopts the narrow spectral signal track to track collection of UV185～260nm flame, the design of overall pulse analytical technology, has avoided the weakness being easily disturbed of conventional detectors.Adopt slope increment signal detection technique to monitor acquisition environment, improved stability and the lasting usability of detector.Ensure that detector, in reducing wrong report, completes the ability of the flame identification detection condition of a fire fast as far as possible, by CPU, sound-pipe has been monitored, extended the service life of sound-pipe.
Ultraviolet flame detectors 5 is applicable to all kinds of: when the fire such as oil depot, Jiu Ku, hangar, chemical industry equipment place, military equipment place, liquefied gas station, power station is sprouted without the stage of glowing or the less stage of glowing, and directly to produce naked light as main place.There is higher antijamming capability, not affected by wind and rain, high temperature, high humidity and natural artificial light source etc., can works fine in indoor or outdoors environment.
Due to kitchen brick kitchen range burner hearth enclose inside, but easily moist, therefore, in the time that brick kitchen range uses the utility model, flame detector is selected ultraviolet flame detectors 5.
Further, in controller 6, be provided with six control points;
Wherein,
Control point L and control point N connect power supply;
Control point 1 and control point 2 connect ultraviolet flame detectors 5, for ultraviolet flame detectors 5 is powered;
Control point 3 connection control point, one end L, the other end connects one end of the first switch 7;
The other end of the first switch 7 connects the one end at control point 4;
The other end at control point 4 connects one end of the first magnetic valve YV1;
The other end of the first magnetic valve YV1 connects control point N.
After control point L and control point N switch on power, for controller 6 is powered; Control point 1 and control point 2 are flame detector power supply; Control point 3 and control point 4 are controlled the first magnetic valve YV1 by the first switch 7.
Manual unlocking the first valve F1 and the second valve F2, firing point lighted torch 2, ultraviolet flame detectors 5 detects the flame of fire rod 2, give controller 6 feedback signals, control point 3 and the control point 4 of controller 6 are connected, and the first magnetic valve YV1 opens, and sub-fire is lighted, open the 3rd valve F3, main fire is lighted; After group fire, main fire all extinguish, ultraviolet flame detectors 5 is surveyed less than flame, gives controller 6 feedback signals, and control point 3 and the control point 4 of controller 6 disconnect, and the first magnetic valve YV1 disconnects, and fuel gas supply all cuts off.
Further, flame detector is ion probe 13, as shown in Figure 3.
Be not subject to the interference of light, thermal and magnetic etc. using ion probe 13 as the safety guard of flame detection resources, be quick on the draw, be swift in motion, have advantages of very large.But, if pollute or moist environment in, will cause electrode insulation resistance to decline, when insulaion resistance drops to while approaching flame internal resistance, circuit can cannot be distinguished real flame current or leakage current, may cause misoperation.Therefore, ion probe 13 need to use in dry environment.
Fry kitchen range and steam box in open space, therefore can use ion probe 13 flame detectors to carry out flame monitoring.Frying kitchen range and steam box adopts ion probe 13 to monitor flame, judge by the weak current between ion probe 13 and the earth whether flame burns, after judgement, result is transferred to controller 6, controller 6 is controlled opening of the first magnetic valve YV1 and is disconnected, thereby further controls gas flow.
Further, gas kitchen ranges safety guard also comprises the second magnetic valve YV2;
One end connexon fire-fighting head 3 of the second magnetic valve YV2, the other end connects Gas Pipe 1;
The second magnetic valve YV2 is in parallel with described the first magnetic valve YV1;
One end of the second magnetic valve YV2 is connected with power supply L by switch S Q, and the other end is connected with power supply N.
Add the second magnetic valve YV2, in use, can first light son fire, connect afterwards the first magnetic valve YV1, refire main fire, can further increase like this safety in utilization of this device.
Further, switch S Q is reset switch.
Reset switch is exactly that one can automatically reset switch in simple terms, and reset switch can be cylindrical, can be also square etc., and what difference it and common switch do not have in shape, but different in function.After reset switch presses down, hand unclamps replys original state.Reset switch and point driving switch are very similar, and it is also the one of point driving switch strictly, but reset switch different from common point driving switch be that the seed selection of reset switch is longer, contact is not a point, but a stroke.
Because the second magnetic valve YV2 is unsuitable long turn-on time, if forget that the situation of disconnection occurs after using self-lock switch may cause closing a switch, therefore the switch S Q in the utility model embodiment has adopted reset switch.
Further, in controller 6, be provided with five control points;
Wherein,
Control point 5 is connected respectively power supply L and power supply N with control point 6;
7 one end, control point connect power supply L, and the other end connects one end of second switch 8;
The other end of second switch 8 connects the one end at control point 8;
The other end at control point 8 connects one end of the first magnetic valve YV1;
The other end of the first magnetic valve YV1 connects power supply N;
Control point 9 connects described ion probe 13.
Control point 9 is inductor, and ion probe 13 detects after flame, has micro-current delivery to 9 places, control point, after 9 energisings of control point, controls second switch 8 closures, thereby is the first magnetic valve YV1 power supply, now, unclamps reset switch SQ, the second magnetic valve YV2 power-off.
Manual unlocking the first valve F1 and the second valve F2, pin reset switch SQ, light son fire with fire rod 2, ion probe 13 detects flame, produce the micro-electric current of 8mA with the earth, the control point 7 of controller 6 and control point are connected for No. 8, and now the first magnetic valve YV1 connects, manual unlocking the 3rd valve F3, main fire is lighted, unclamp reset switch SQ, the second magnetic valve YV2 disconnects automatically, and sub-fire-fighting head 3 is supplied with combustion gas by the first magnetic valve YV1; After group fire, main fire all extinguish, ion probe 13 is monitored less than flame, and 8mA current vanishes between the earth, and control point 7 and the control point 8 of controller 6 disconnect, and the first magnetic valve YV1 disconnects, and fuel gas supply all cuts off, and reaches the effect of blowout protection.
The utility model gas kitchen ranges safety guard; reduce safety mechanical to hold up and become electronic control; respond to flame by flame detector; access control device 6 in the line again; can control magnetic valve; thereby efficiently solve the defect that mechanical device cannot be opened, avoided the situation that the main fire of kitchen range cannot be lighted to occur.
This gas kitchen ranges safety guard is the innovation achievement of developing voluntarily completely; maintenance cost has been saved in the application of this device; more crucial is to have eliminated the potential safety hazard such as gas leakage, fire, not only has good promotion prospect, and has higher commercial value.
On market, only there is the flame-out protection device of thermojunction type and ionic formula for household cooker; but not yet ultraviolet flame detector is used for to kitchen range safeguard protection; therefore; ion probe 13 and ultraviolet flame detector will have more development aspect family expenses, commercial kitchen range safeguard protection; in conjunction with leakage alarm, the interlock of blower fan function, will usher in a new era for the security developments of gas kitchen ranges on this basis.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
