Description

Safety controlling device for domestic gas cooker

The utility model relates to a kind of domestic gas cooking stove control and security fields.Household electrical appliance cooking stove in the market, have and when gas leakage, adopt electronics olfactory organ and the control exhaust gas leakage combustion gas of ventilating fan one and olfactory organ is housed on smoke exhaust, drain gas with smoke exhaust, reach safety measure, but shortcoming is that just to have lost the control function when having a power failure be not have a power failure, because valve is not closed, combustion gas is leaked in a large number, ventilating fan have to constantly be got rid of, and causes gas to waste in a large number.

Kitchen range of supplying on the above-mentioned market and smoke exhaust are all failed to solve smoke evacuation and are closed interlocking automatically with the control cooking stove, therefore safety just can't guarantee when combustion gas is hit the back and meeting of going out and had a power failure by spilling water, thereby combustion gas causes fire and the great pernicious casualty accident of generation when leaking in a large number.

The purpose of this utility model provides a kind of no electrical safety devices, can prevent to hit the combustion gas of going out when spilling water is flowed out, and burnt gas switch is closed automatically, the control gas-cooker, stop the generation of gas leakage and pernicious casualty accident, and can play safe and reliable safety effect, guarantee safe handling.

Task of the present utility model is achieved through the following channels: the domestic gas cooking stove and the safety control thereof that are provided, it is by safety guard 1, safety board 2, furnace shell 22 gaps 3, spilling water bucket 5, lever 4 and gauge tap 6, balance pivot 7, spring 8, prerotation vane 9, rationed marketing 10, guide pin bushing 11, counterweight 12, untie-sell hole 13, burnt gas switch 14, adapter sleeve 15, driving wheel 16, control spring 17, shift fork 18,19, nut 20, chassis 21, timer 23, turn-knob 26, timing pin 24, the collar 25 compositions such as grade, when spilling water flows to safety board 2 outsides through safety guard 1 when kettle wall portion overflows, promptly flow on the furnace shell 22, spilling water is flowed in the spilling water bucket 5 accurately, when spilling water bucket 5 spilling waters that are hung in lever 4 tail ends reach a certain amount of or by artificial, close burnt gas switch 6 when making its whereabouts certain distance by its lever middle part downwards, it is fixed in lever termination rationed marketing 10 by balance pivot 7, when extracting by guide pin bushing 11, make control spring 17 resiliences of driving wheel 16 inside, driving driving wheel 16 rotates, make and be installed in driving wheel 16, shift fork 19, counterweight 12 forces it to be fixed on the coaxial burnt gas switch 14 of going up, shift fork 18 rotates together, and burnt gas switch is closed.

Timer 23 is equipped with at 21 middle part on the chassis, its axle is equipped with timing pin 24, hangs the bucket 5 except installation at the tail end of lever 4, is fixed with the collar 25 and matches with timing pin 24 on the timer 23, knob 26 is fixed on the pin collar 25 lower ends and plays position-limiting action, to reach dual fail-safe.

Advantage of the present utility model: cooking stove is equipped with automatic safe closes gas combustion apparatus, makes spilling water overflow difficult combustion gas is hit in back and goes out, and under no electric situation, can play the effect of safe and reliable dual fail-safe, stops the generation of gas leakage and pernicious casualty accident.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a domestic gas cooking stove control safety device stereogram;

Fig. 2, the 3rd, domestic gas cooking stove control safety device structure control figure;

Fig. 4, the 5th, domestic gas cooking stove control safety device timing means schematic diagram;

The utility model gas stove control safety device stereogram, as shown in Figure 1, formed by safety guard 1, safety board 2, gap 3, furnace shell 22, lever 4, spilling water bucket 5, gauge tap 6, burnt gas switch 14, driving wheel 16, prerotation vane 9, timer 23, timing pin 24, spilling water canal 27, conduit 28.When cold water is boiled, the water that overflows is by safety guard 1, furnace shell 22 flows into gap 3 along spilling water canal 27, the oral area of gap 3 is equipped with conduit 28, spilling water is flowed in the spilling water bucket 5 accurately, when spilling water reaches a certain amount of, weight in the bucket increases, force the tail end of lever 4 sagging reach certain apart from the time, will close automatically, be equipped with the switch 6 of closing combustion gas control driving wheel 16 in the middle and upper part of lever 4, prerotation vane 9 is equipped with burnt gas switch 14 at driving wheel 16 middle parts, and burnt gas switch is closed automatically, tail end at lever 4 also is equipped with timer 23 and timing pin 24, reaches the dual fail-safe effect.

The utility model domestic gas cooking stove structure control figure, as Fig. 2, shown in Figure 3, formed by lever 4, spilling water bucket 5, gauge tap 6, balance pivot 7, spring 8, prerotation vane 9, rationed marketing 10, guide pin bushing 11, counterweight 12, untie-sell hole 13, burnt gas switch 14, adapter sleeve 15, driving wheel 16, control spring 17, shift fork 18,19, nut 20, chassis 21.In the middle and upper part of lever 4 burnt gas switch 6 is installed, spring 8 and prerotation vane 9 are equipped with in the bottom, are fixed on the chassis 21.After lever 4 is subjected to external force and rotates, because of its afterbody links to each other with spilling water bucket 5, must move upward by its lever portion fulcrum 7 and the rationed marketing 10 that is fixed on the termination, rationed marketing this moment 10 must be by after extracting in the untie-sell hole, top 13 on fairlead 11 driven pulleys 16, this moment, driving wheel 16 was equipped with control spring 17 because of its inside, its end be fixed on driving wheel 16 in put, one is fixed on the chassis 21, before opening burnt gas switch, must rotate earlier driving wheel 16 and reach 180 when spending, meet with rationed marketing 10 in untie-sell hole 13, because lever 4 is under the effect of spring 8, pin with rationed marketing 10 in untie-sell hole 13, energy storage capacity has also produced bounce to control spring 17 thereupon because manpower rotates this moment, if the spilling water bucket that lever 4 hangs strengthens weight, rationed marketing 10 just can break away from untie-sell hole 13, this moment, driving wheel 16 internal control springs 17 produced screen resilience, driving driving wheel 16 rotates, because driving wheel 16 is rotatably installed in the counterweight 12 on it, shift fork 19 rotates together, thereby causes rotating with shift fork 18 coaxial burnt gas switch 14 burnt gas switch 14 is closed automatically, also burnt gas switch 14 lockings is got up simultaneously, this is the effect of control spring surplus energy, thereby reaches the purpose of automatic self-closing gas switch 14.On the axle of burnt gas switch 14 shift fork 18 is housed, burnt gas switch 14 all is contained in the centre bore of moving opinion 16, and adapter sleeve 15 is fixed together by chassis 21 with nut 20.

The utility model domestic gas cooking stove timing means schematic diagram, shown in Fig. 4,5, it is made up of timer 23, pin 30, timing pin 24, the collar 25, turn-knob 26, reverse 29 etc.Afterbody at lever 4 is fixed with the collar 25, there be reverse 29 at the bottom of the collar, pin 30 on it and the timer 23 matches, timing pin 24 is coaxial with pin 30, and on the chassis timer 23 is equipped with at 21 middle part, axial region is equipped with pin 30 and matches with the turn-knob 26 of the collar 25 lower ends, and position-limiting action is played in the collar 25 lower ends.

The safety guard 1 of the utility model gas stove control safety device must be greater than the size of safety board 2, safety board 2 is installed in the fire door oral area, its angle is the 5-10 degree, water that overflows like this and steam are unlikely to be splashed in the fire door, and can flow into gap 3 smoothly, reach the purpose of control fuel gas buring.
