Below again in conjunction with Fig. 5 and Fig. 1 circuit link, using method: divide three kinds of operating positions under " need not use timer " and " needing the use timer " and the power failure situation to be further described.

In the time need not using timer, earlier timer turn-knob 35 is gone to " ON " position, 2 contacts of this moment A, B, the C point is charged, and the D point is charged all the time, the E point is also charged all the time.Suppose to use earlier left side kitchen range, press stove and accessory valve turn-knob, counterclockwise rotation, leverage action, contact 5 is upturned, and slip over mutually with the contact on the right, contact in a flash, emitter 4 on-off circuits are connected, send the signal instruction of " driving valve ", receiver 9 is received signal, circuit turn-on, and the power supply indicator 10 on the cover is glittering, valve solenoid 12 energisings before the kitchen range, the suction that produces sees through dividing plate 13, and armature 14 is picked up, and drives ratchet and pushes away for 18 times, ratchet 20 is half-twist immediately, make the through hole of the preceding valve core 19 of kitchen range, aim at the combustion gas of valve body two ends and import and export, combustion gas is admitted to kitchen range.After the right and left circuit trigger contacts in a flash and slips over, the contact 5 on the left side arrives the position of " F ", circuit disconnects immediately, signal stops, and the electromagnetic coil circuit of valve also disconnects immediately before the kitchen range, and armature 14 left ends fall, and ratchet 18 is upwards mentioned, be tapped in two ratchets, wait for next " closing " signal instruction.After the gas circuit conducting in a flash, continue inverse clock rotation stove and accessory valve turn-knob, stove and accessory is lighted a fire, the left side stove and accessory state that comes into operation.

After if left side stove and accessory comes into operation, use the stove and accessory on the right again simultaneously, then counterclockwise rotation the right stove and accessory valve turn-knob, 5 of the contacts of the right quarter butt bar do not contact with left side contact 5, and slide into the position of " G ", and combustion gas still keeps clear, the right stove and accessory igniting, state comes into operation.

When supposing to close earlier left kitchen range, the circuit trigger 5 on the left side is got back to original position, does not contact with the right circuit trigger 5 that is in " G " position, and combustion gas is still being passed through, and the kitchen range on the right is still using.When closing right kitchen range, the circuit trigger 5 on the right slips over of short duration again contact of the contact 5 on the left side, the another moment connection of emitter 4 on-off circuits, send the instruction of " closing " signal, receiver 9 conductings, valve electromagnetic mechanism and transmission mechanism are worked immediately before the kitchen range, air flue is cut off and close.The circuit trigger on the right is got back to original position again, treats to use next time.

Again the operation principle and the specific operation process of timer is described further below.

Open stove and accessory valve point fire earlier, rotary timer turn-knob 35 goes to and needs the setting-up time position clockwise again, in process regularly, A, B contact all the time, in case reach setting-up time, brake bar 32 is pushed ratchet 28 open, and 2 of A, B pop up simultaneously, and contact with the E point, transmitter circuitry is connected automatically, the receiver conducting, and valve is worked immediately before the kitchen range, blast tube is closed, the stove and accessory fray-out of flame, 3 still contacts of A, B, the E in the timer at this moment, armature 14 is still held, and send the buzzing sound, the prompting user " time is up! Fire is closed ".Give the correct time sound about 30 seconds, the elasticity tip 26 is shifted peak to brake bar 32 onto, and brake bar moment falls in the middle of the concave point of runner 36, and A, B, 3 of E separate simultaneously, and transmitter circuitry interrupts, and signal stops, and buzzing is given the correct time and is also stopped thereupon.At this moment earlier stove and accessory valve turn-knob is turned off, again the turn-knob of timer is gone to " ON " position, make 2 contacts of A, B in the timer, so that use gas kitchen ranges next time.

Again the use of kitchen range under the power down mode is made an explanation below: when having a power failure, the turn-knob 22 that earlier valve face before the kitchen range is covered by prior art changes 90 ° clockwise to the position of opening, stove and accessory is used in igniting again, when closing fire, close the stove and accessory valve earlier, this moment, valve cut out automatically before the kitchen range if there is electricity to send here, if no electricity is sent here, the turn-knob 22 that then valve face before the kitchen range is covered changes 90 ° of positions to the pass clockwise and gets final product.

The present invention reaches on the basis of " multifunctional fuel automatic safety device " in former patent " combustion gas nature safety valve "; realized wireless control again from wired control; realized again that from original pneumoelectric separation the kitchen range electricity separates; signal transmitter installation and signal receiver apparatus have been increased; that has set up stove top, combustion chamber lid prevents that spilling water is flame-out, windproof flame-out draining protective cover and hurricane globe unique construction.Timing control apparatus except can make the user feel to use very convenient, also have and save combustion gas and the flame-out function of protection automatically.The automatic switch of valve, hand switch, the anti-flame-out special type structure of burner and timing automatic closing before the kitchen range, automatically alarming then, the combination of multiple function, so just formed one not only easy to use but also have a powerful camp that maltilevel security is protected.

The utility model utilization electric signal automatic control technology, make the general gas kitchen range enter electronization, intelligent Automatic Control, more preceding two patents are compared, and the utility model technology content is higher, function is comprehensive more, structure is more perfect, safety has higher guarantee, moulding also exquisite more.Cheap cost cost is easily accepted by market, and multiple safeguard protection can further improve people's quality of life, can provide more strong guarantee for the safety of vast combustion gas user lives and properties.
