Synchronous fuel gas stove

Affiliated technical field

The present invention relates to a kind of multiple function that has; the gas-cooker of new generation of comprehensive, three-dimensional safeguard protection; include electronics, machinery, regularly, the blowout protection interlocking system; and supporting design has the preceding valve of automatic kitchen range; supporting design and installation automatic cooking fume exhauster; (or exhaust fan) realizes " interlock of three machines ", reaches the purpose that works asynchronously with gas-cooker.Belong to gas kitchen ranges, special valve, special-purpose timer, electronic production technology field.

Background of invention

The mankind have experienced the historical process in thousands of years from burning bavin, burning coal until modern use combustion gas, and along with China's transfering natural gas from the west to the east strategy implementation, it is universal widely to use combustion gas to obtain, and its wholesomeness, convenience are subjected to welcoming widely.Yet, the development that the gas-cooker technology still is out of step with the times, many although security protection technology has improved, single protection can't resolve the security incident that multiple reason causes.Serious accidents such as poisoning, fire, blast still happen occasionally, and people's lives and properties are often suffered unnecessary heavy losses.Still can not find effective method at present and thoroughly effect a radical cure the gas leakage accident, and only way is: each big city gas company is spared no high price, month after month point out at dusk the user every day on TV: ", please in time closing the kitchen range early gate after the use combustion gas " for you and family's wellbeing throughout the year! But leakage accident still happens occasionally!

The various leakage accident analyses of causes

Soup extinguished combustion gas under overflowing when a. gas-cooker was worked, and caused accident to take place.

B. use and forget behind the kitchen range and close valve before the kitchen range, the kitchen range sealing is bad, hose aging, joint are loosening, causes accident to take place.

C. gas-cooker is not put and is caught fire, and the user does not find, causes accident to take place.

Supply gas again after stopped the supple of gas or steam by accident when d. gas-cooker is worked, or wind is flame-out, causes accident to take place.

E. gas-cooker when work user forgets and opens smoke exhaust ventilator, and (or exhaust fan) produces a large amount of pernicious gases accumulation, causes intoxication accident to take place.

F. in gas-cooker when work,, the user leaves and forgets and close, and dry combustion method takes place, and causes food vessel damage accident.

G. people's reason of being comprises suicide, deliberately destroys, and (pull out sebific duct, open valve venting before the kitchen range) causes the generation of the great serious accident of gas leakage.

The prior art background

The gas-cooker that has blowout protection in the market mainly contains two kinds of styles: a kind of is gas-cooker with the thermocouple sensing device, and another kind is the gas-cooker of band ion pulse induction installation.Because the thermocouple reaction time is too slow, need pin turn-knob about seven seconds after the igniting, taking place needs just can close magnetic valve tens of seconds when flame-out, exists and leaks hidden danger, and the user uses also inconvenient.The gas-cooker of band ion pulse induction installation is comparatively advanced at present a kind of style, but remains in certain defective, the ion pulse device with kitchen range work up to closing, battery power consumption is big, need often to change battery, when making troubles, increase customer using cost.Because the gas-cooker of above-mentioned two kinds of styles; its magnetic valve is installed on the main breather pipe; when a burner takes place to stop working; the burner of another work of burning is also closed simultaneously; and kitchen range valve turn-knob is still located open mode; just in case the generation mechanical breakdown might cause new potential safety hazard, and the gas-cooker of these two kinds of styles can only be considered to only have the gas-cooker of single defencive function.

The former patent No. of applicant: 00232756.2 " multifunctional fuel automatic safety device ", the patent No.: the solution that 01230969.9 " multifunction electronic intelligent and safe gas-cooker " is successful valve can not the automatic switch technical barrier before the pipeline kitchen range.Original applying number: what 02125024.3 " RF-type intelligent electronic gas stove with high protection function " was successful provides a kind of without electric energy; with the flame-out protection device under spilling water self gravitation, the centrifugal force effect; but foregoing invention has only solved the part technology; remain in certain deficiency, can not stop the gas leakage security incident comprehensively.

The present patent application people is through for many years investigation; at the various cause of accident labors of gas leakage; for fundamentally stopping gas leakage accident potential, the design of the single defencive function of gas-cooker that breaks traditions has proposed a kind of brand-new design idea " ultimate protection " design concept.Design content comprises gas-cooker, automatically valve, smoke exhaust ventilator before the kitchen range, (or exhaust fan) with the kitchen range igniting, regularly, close and four projects of blowout protection in, realize " interlock of three machines ", reach the purpose that works asynchronously with kitchen range.Make comprehensive, the three-dimensional of domestic gas safeguard protection, disposable putting in place with this safety of guaranteeing people's lives and properties, exempted hundreds of millions family's trouble and worry, promotes combustion gas industry health and develops smoothly.

As seen from Figure 10: heat memory driving switch 68 includes memory metal sheet 79, bimetal leaf 80, porcelain knob 77; the bimetal leaf circuit is a normally-closed contact; be installed in the cavity of porcelain knob, the lower end is fixed on the porcelain knob, and is connected with electronic ignition blowout protection music circuit 83.(as shown in Figure 9) a slice top curved and stretching out wherein in the outside of porcelain knob window 78, memory metal sheet one end is fixed on the porcelain knob top, and the other end is downwards crooked and press an end that stretches out sheet metal bending outside porcelain knob, and the bimetal leaf circuit is connected.After combustion gas is lighted or is extinguished, under the driving of memory metal sheet, bimetal leaf under self elastic force, disconnect voluntarily or closed circuit.Because the bimetal leaf circuit contact is installed in the porcelain knob cavity, be not subjected to that high temperature scorches, spilling water corrodes, it is durable in use to be difficult for oxidation, can guarantee the circuit long-term stable operation.

Below again in conjunction with Figure of description Fig. 1, Fig. 5, Fig. 7, Fig. 9, Figure 10, the using method branch " need not use timer ", " needing to use timer ", " water-collecting tray blowout protection interlinked mechanism operation principle ", " the heat memory driving switch blowout protection course of work and unexpected sudden and violent the leakage are cut off source of the gas automatically " reach " using method under the power down mode " and make further instruction:

Before kitchen range use, smoke exhaust ventilator hand switch 18 should keep the breakdown state under normal conditions, when using kitchen range, should push the insurance push button 2 at two ends to left end earlier, lever ratchet 47 blocks the recess of motion bar 41, locate anodontia neutral gear 38 positions between tooth bar 39 and the half cycle ratchet 37, spring ratchet interlinked mechanism 44 is under stable safety position of director's phase under compression spring 42 effect.(as Fig. 5, shown in Figure 6) is in the time need not using timer 32, regularly turn-knob 6 should be in the position of " ON ", (as shown in Figure 1) resilient key 35 of timer is in the below of lever ratchet 47A end, (as shown in Figure 5) suppose the stove fire of use left end earlier, then press left end kitchen range valve turn-knob 4, the counterclockwise rotation, left end leverage 7 interlocks, circuit trigger 8 is upturned.And rub mutually with right-hand member leverage circuit trigger and to slip over, flashy contact, emitter 13 circuit are connected, indicator lamp 14 is glittering, sends the instruction of " breakdown " electric signal, and receiver 20 is received electric signal, executive circuit work, power supply indicator 19 is glittering on the cover, the equal triggering and conducting of unidirectional, bidirectional triode thyristor, and smoke exhaust ventilator 17 (or exhaust fan) enters the running duty.Simultaneously, electromagnet coil 16 circuit of valve are connected before the kitchen range automatically, and the suction of generation picks up armature 21, drive ratchet and push away for 30 times, and ratchet 26 revolves immediately and turn 90 degrees, and the combustion gas at through-hole alignment valve body 27 two ends of poppet shaft 29 is imported and exported, and combustion gas is admitted to kitchen range.When the circuit trigger 8 of leverage contact in a flash slip over after, the contact of left end slides into the position of " F ", (as shown in Figure 8) circuit disconnects immediately, signal stops, the circuit of electromagnet coil 16 disconnects simultaneously, and armature 21 left ends fall, and ratchet 30 is upwards mentioned, be tapped in two gear teeth, wait for the signal instruction of next " closing ".And the preceding valve of automatic kitchen range this moment has been in no power consumption ventilation duty.When kitchen range valve turn-knob rotates, electronic igniting circuit K switch 1 and kitchen range valve interlock, firing circuit is connected, spray point 65 discharges, music integrated circuit 84 work are sent music or voice suggestion as " light a fire, the user please notes! " after combustion gas lighted, heat memory driving switch 68 disconnected bimetal leafs 80, (as shown in figure 10) voice suggestion stops, and can regulate this moment to the firepower size.

After if the stove fire of left end comes into operation, need use the stove fire of right-hand member again simultaneously, pressing right-hand member turn-knob counterclockwise rotates, right-hand member leverage circuit trigger does not contact with the left end contact, and slide into the position of " G ", (as shown in Figure 8) right-hand member and left end use and all to have above-mentioned functions, the right-hand member stove fire state that comes into operation.Suppose to close earlier the left end stove fire, the salient point 82 of turn-knob end face promotes an end of long lever 11, and the circuit trigger of left end arrives original position together, and does not contact with the contact of right-hand member, and the right-hand member stove fire is still in normal use, when closing the stove fire of right-hand member, the contact of right-hand member and the contact of left end rub mutually and slip over, the another moment connection of transmitter switch circuit, send the instruction of " closing " signal, receiver circuit is triggering and conducting simultaneously, and the valve electromagnetic mechanism is worked immediately before the kitchen range automatically, cuts off gas circuit and closes.The oily machine of smoking simultaneously also cuts out immediately.After kitchen range cut out, the circuit trigger of right-hand member was got back to original position, (as shown in Figure 8) at the same time firing circuit K switch 1 disconnect simultaneously because stove fire temperature sharply disappears, heat memory driving switch 68 sets back, bimetal leaf 80 closings of circuit are used to treat next time again.

Now the operation principle and the specific operation process of timer are made an explanation:

Divide " using a timer " to reach the method for operating of " using two timers simultaneously ".

When using a timer 32, open an end kitchen range valve point fire earlier, regularly turn-knob 6 clockwises go to setting-up time again, and the resilient key 35 of timer slips over the A end of lever ratchet 47 at this moment, enters definition status.When reaching setting-up time, under the effect of winder 10, working arm 33 revolutions, resilient key 35 is pushed lever ratchet 47A end open, the upper end gets loose, motion bar 41 is under the effect of compression spring 42, and drive tooth bar 39 is pushed to right-hand, and tooth bar promotes half cycle ratchet 37 clockwises and rotates, drive kitchen range valve turn-knob 4 interlock leverage 7 actions simultaneously, circuit trigger rubs mutually and slips over, and the transmitter switch circuit is connected, and valve and smoke exhaust ventilator are closed simultaneously with kitchen range before the kitchen range automatically.At this moment earlier the timing turn-knob is gone to the position of " ON ", make resilient key be in the below of lever ratchet A end, (as shown in Figure 5) will be insured push button 2 again and push right-hand member to, so that use next time.Use the insurance push button if the user forgets, tooth bar will block the half cycle ratchet, kitchen range uses of can't lighting a fire, and have the function of the operation of preventing, correct a mistake, guarantee the user security use.When the user need use two timers simultaneously, suppose to open earlier the right-hand member stove fire, regularly ten minutes, opened the left end stove fire more regularly 20 minutes, right-hand member stove fire setting-up time one arrives, and right-hand member spring ratchet interlinked mechanism starts, and the right-hand member stove fire is closed.The left end stove fire is still continuing use, when left end stove fire setting-up time one arrives, left end spring ratchet interlinked mechanism starts closes the left end stove fire, (valve and smoke exhaust ventilator are closed simultaneously before the kitchen range automatically) at this moment forwards the timing turn-knob to " ON " position respectively, pushes the insurance push button at two ends to left end again and gets final product.(as shown in Figure 1)

Now again water-collecting tray blowout protection interlinked mechanism operation principle is made an explanation:

When the user cooking or the process of heating up water in leave; or set regularly long; cause boiling water to overflow down; when dangerous situation takes place to stop working; first heavily protection spilling water is directly arranged to furnace bottom by groove 74 by waterproof burner 63 and draining stone or metal plate for standing a stove on as a precaution against fire 73; spilling water is connected in the water-collecting tray 61 of burner below by receipts; and flow to water-collecting tray than the B at end end; B end weight constantly increases; because the effect of gravity; the B end is downward-sloping; under the effect of gravitation, the steel ball 53 of water-collecting tray both sides rolls the end to B along steel ball box 55 rapidly, and the weight of B end increases suddenly; water-collecting tray; steel ball is pressed an end of interlock lever 56 rapidly together with the weight of spilling water; the B end of the other end jack-up lever ratchet 47 that the interlock lever is bent upwards is (as Fig. 5; shown in Figure 7) ratchet unclamps, and spring ratchet interlinked mechanism starts immediately; the kitchen range valve cuts out automatically (valve before the automatic kitchen range; smoke exhaust ventilator is closed simultaneously)

The blowout protection post-processing approach is to set like this: earlier the kitchen range front end is upturned with hand, steel ball 53 is rolled into steel ball box 55A end original position, wipes the spilling water on the clean kitchen range top routinely, kitchen range is kept flat down again, and this moment, water-collecting tray was located plateau under steel ball weight.To insure push button 2 again and push left end to, kitchen range enter safety position once more.If the user has used timer, setting-up time is long, causes boiling water to overflow down, and when producing the flame-out harm of spilling water dangerous situation, water-collecting tray blowout protection interlinked mechanism, spring ratchet interlinked mechanism will move in advance, in time the kitchen range valve cut out.(valve, smoke exhaust ventilator are also closed simultaneously before the kitchen range automatically) at this moment goes to " ON " position with timing turn-knob 6 earlier, handles getting final product again as stated above.

Now again the heat memory driving switch blowout protection course of work is made an explanation:

After the kitchen range normal ignition uses; if supply gas again after stopped the supple of gas or steam by accident or stove fire is extinguished in wind; (comprising that spilling water is flame-out) is when producing the gas leakage dangerous situation; because of temperature sharply descends; heat memory driving switch 68 is worked immediately; memory metal sheet 79 sets back; and press and stretch out a sheet metal one end outside window 78; bimetal leaf 80 is in contact with one another closure; circuit is reclosed, and (as shown in figure 10) firing circuit restarts, the spray point discharge; music integrated circuit is played music again and is pointed out the user; within the several seconds if misfire the delay circuit conducting in the circuit, the 49 energising work of electromagnetism pull-in winding; driving spring ratchet interlinked mechanism 44 is (as Fig. 5; shown in Figure 6) close kitchen range valve (automatic valve before the kitchen range; smoke exhaust ventilator is closed simultaneously) reach " interlock of three machines " blowout protection purpose.

Now again the using method under the power down mode is made an explanation:

When having a power failure, automatically valve, smoke exhaust ventilator can't start before the kitchen range, the manual Ji of lampblack absorber can be closed 18 turns off, now by prior art with automatic kitchen range before the position that goes to out of turn-knob 31 clockwises that cover of valve face, kitchen range are used in igniting again, when closing stove fire, close the kitchen range valve earlier, this moment is if there is electricity to send here, automatically valve cuts out simultaneously before the kitchen range, opens smoke extractor hand switch 18 again, if no electricity is sent here, the position that then valve turn-knob clockwise before the automatic kitchen range is gone to the pass gets final product, and opens smoke exhaust ventilator hand switch 18 again and uses to treat next time.

Now leak reason and cut off the source of the gas operation principle automatically and make and further specifying combustion gas is unexpected sudden and violent again:

In the gas leakage harm that multiple reason causes, it is comparatively rare that the sudden and violent phenomenon of leaking takes place, but still the time report for work, its mainly produce former because: combustion gas sebific duct two ends snap close does not connect the jail, suffer accidental release, commit suiside or artificial intentional destruction, (mainly show as and pull out the combustion gas sebific duct, valve is exitted before opening kitchen range), cause combustion gas to leak the generation of serious accident cruelly.One family leaks, and jeopardizes neighbours, even all will cause serious consequence to entire building room and whole sub-district.For preventing the existence of this type of serious accident hidden danger, before automatic kitchen range of the present invention in the inlet end of valve body 27, setting is placed with a movable anti-riot pearl 25, (as shown in Figure 1) anti-riot pearl is made by light and soft matter rubber of anti-solvent the or plastics, when in case the great dangerous situation of above-mentioned sudden and violent leakage takes place, a large amount of combustion gas in the pipeline before kitchen range the valve gas outlet spouting, under the gas-flow of relatively high pressure, anti-riot pearl is blown to the through hole of the less end of valve body inlet end rapidly, blast tube is tightly blocked, can guarantee in time to cut off whole source of the gas passage, prevent the generation of great pernicious gas leakage accident.

The present invention is on the basis of preceding several patents, collecting five technology elite is one, gas-cooker, the preceding valve of kitchen range, three of smoke exhaust ventilators separately use different technical products in the last hundred years, interlock combination by present technique utilization hyundai electronics, mechanical technique, become a brand-new technology integral body, can open or close the valve of two different technologies of a blast tube automatically.Waterproof burner of the present invention can effectively be reduced to bottom line with the flame-out harm of spilling water.Water-collecting tray blowout protection interlinked mechanism is original in style especially, the humble pressure that does not need any electric energy spilling water can be produced, and moment is converted to relatively high pressure, automatic self-closing gas kitchen range, solved and account for flame-out reason 80% above accident rate.Electronic ignition blowout protection music circuit compared with prior art; have very big advantage, the gas-cooker stove fire is the no power consumption monitor state in place when work, and does not need at the kitchen range airway magnetic valve to be set; simultaneously all can be at igniting, blowout protection with the voice suggestion user, and directly drive and close the kitchen range valve.

The present invention is lever-linked mechanism, spring ratchet interlinked mechanism, timing means, water-collecting tray blowout protection interlinked mechanism, electronic ignition blowout protection music circuit; streamlined electronics, mechanical interlocking system have been formed by valve, the whole mechanisms of smoke exhaust ventilator before the automatic kitchen range of signal transreceiver structure handle; every kind of existing independent function of use of mechanism; can protect by the overall co-ordination interlock again; the interlock combination of multiple function has realized that gas-cooker " interlock of three machines " is synchronous

The purpose of work has high automaticity, puts the safeguard protection of comprehensive, three-dimensional in place for the user provides disposable.

The present invention has broken through the design of the single defencive function of prior art, and is novel, unique, practical, and the creativeness of very outstanding inventive point and macroscopic view is arranged.Can on the prior art basis, further provide more function and higher safeguard protection for the user!

The present invention is suitable for kitchen range, special valve, special-purpose timer, electronic technology manufacturer Development and Production.
