Description

A kind of boiling with gas oven on-off control system and device thereof

Technical field

The present invention relates to stove and accessory, particularly fast and security is good boils with gas oven on-off control system and device thereof about a kind of speed of ignition.

Background technology

The occupation mode of known gas oven, nothing more than adopting following dual mode, first kind is that the switching knob of pushing earlier on the stove and accessory then rotates, second kind does not then need the push switch knob and rotation at once, the closd rod that dual mode must make gas switch inside is the Valve plug of pushing tow magnetic valve forward, allow outside gas source flow in the Switch main body via the gas source inlet, the hole shunting gas source of closing son periphery by adjustment flows into female fiery passage and burner respectively encircles in the passage separately again, finishes burner and lights operation.The igniting triggering mode of these gas switch, not that the quartzy bump generation of utilization spark is exactly that the continuous discharge that utilizes microswitch to produce is lighted female fiery, after female fire ignited and ignite each ring of gas burner, the user still need continue to press switching knob 2～3 seconds this moment.

This known mode of operation, be to set in advance and sense the magnetic valve that high temperature could become thermal power transfer electric current and reach switch inside through electric wire at the other thermocouple of burner, make the electromagnet in the magnetic valve adsorb the valve rod that a inner is provided with iron plate, allowing contracts in the Valve plug of passage because of the valve rod outer end in the gas switch keeps unimpeded, continue to provide the burner gas source, move because of magnetic valve this moment, and the user just can decontrol switching knob fully.In other words, and even one of the function of above-mentioned magnetic valve be to provide outside gas to flow into continually on the burner of gas switch inside; From another point of view, when closing stove fire or gas stove fire when being put out by wind or soup juice, magnetic valve can't obtain enough electric currents because of end flue temperature continues decline this moment, make Valve plug be subjected to the spring pushing tow and get back to the blocking-up gas channel the position, reach the second kind of function that leaks in automatic closed gas source.The magnetic valve of this collocation thermocouple temperature sensitive uses so far and has for many years, though can meet the security regulations demand basically, but be cooled to the time that thermocouple produces response signal and then allows the magnetic valve Valve plug seal when burner is flame-out, usually need tens of seconds, even 1 minute, therefore the situation that still has gas to leak during this section is not improved part to the greatest extent for using the gas switch of magnetic valve at present.

Secondly, when above-mentioned known safety switch uses, when rotary switch knob pushing tow magnetic valve Valve plug, female fiery gas and stove fire gas all flow into switch inside from same gas inlet, closing sub-angle by control again makes gas branch to female fiery passage and burner separately respectively to encircle passage with feeder gas burner outside lock in time almost, therefore if female fire can't be put right in the several seconds smoothly, near the high concentration gas of then accumulating and accumulating in the burner successfully produces unexpected loud noise with a bang, very danger because of afterwards igniting easily.What is more, if the ignition module fault of gas switch promptly can cause burner gas to leak in a large number at short notice and make us uncomfortable situation.In other words, the female fiery gas of known gas oven burner, stove fire gas source flow into the inner burner outside of also flowing out simultaneously of gas switch synchronously by same gas inlet, at short notice at a large amount of gas of burner periphery accumulation, have the problem on the safety easily.

The above-mentioned electromagnetic type gas switch that is all present use is in the igniting of control burner and the reply burner is flame-out or burst not attaining when flame-out improved part.

Summary of the invention

Main purpose of the present invention is to provide a kind of and boils with gas oven on-off control system and device thereof, and it has the advantages that speed of ignition is fast and security is good.

Another object of the present invention is to provide a kind of and boil with gas oven on-off control system and device thereof, gas switch inside does not need to be provided with magnetic valve, can effectively improve long and easy out of order shortcoming of magnetic valve reaction time.

The specific embodiment

For purpose of the present invention, characteristic and effect further are described, after enumerating two preferred embodiments and conjunction with figs. below and being illustrated in.

At first, as Fig. 1～shown in Figure 4, be used in the situation of twoport gas oven for gas switch control system of the present invention, but be not can only be applied on the twoport stove, the gas oven of all single port, three mouthfuls even more mouthfuls also can use native system, in other words, this on-off control system is applicable to that various boiling use Gas cooker.In the present embodiment, it includes: a gas source pipeline 10; One gas shunt conduit 20, corresponding in the present embodiment twoport gas oven are divided into the first gas shunt conduit 20A, and the second gas shunt conduit 20B deciding according to what of burner quantity when practical application fully.Two gas shunt conduit 20A, 20B are not connected, have stopped up a bolt respectively on the top of two gas shunt conduit 20A, 20B, avoid methane gas to leak from top end.Two gas pressure differential disc 30A, 30B, its structure is identical, is separately positioned on first and second gas shunt conduit 20A, 20B stage casing aperture position.As shown in Figure 4, be example with 30A, each gas pressure differential disc, include a housing 31A, have a gas source inlet end 32A, which is provided with a Valve plug 33A, be provided with a film 34A in housing 31A inside, film 34A is divided into positive and negative pressure two rooms with housing 31A inner area.One side gas channel 35A is communicated with positive and negative pressure two rooms, is used for flowing into negative pressure room from gas source inlet end 32A through the malleation room for the gas source.Whether one plug part 36A is subjected to a magnetic valve 37A interlock, is used for opening or closed gas valve port 38A, can flow in the negative pressure room with control gas source.Film 34A both sides are subjected to the positive and negative pressure gas from the gas source often, mutually the balance not inclined to one side state of maintaining a neutral stance.One female burning things which may cause a fire disaster copper pipe 39, one ends are connected in addition side outlet end of gas pressure differential disc 30A housing 31A, are communicated with the female fiery gas of the negative pressure room in the pressure differential disc 30A, the other end then communicate with gas switch (chatting again after the appearance).

As shown in Figure 2, two gas tube connector 40A, 40B divide to be located at the terminal both sides of first and second gas shunt conduit 20A, 20B, and the gas source and course after each pressure differential disc 30A, 30B switch is gone in the gas inlet of gas switch.The structure of two gas switch 50A, 50B identical (following only represent explanation) with 50A, a corresponding gas burner 70A, 70B are provided with respectively, extremely shown in Figure 9 as Fig. 5, gas switch 50A has the associated component identical with known gas switch substantially, gas inlet 51A as switch one side, the conical chamber 52A of body interior, close assemblies such as sub-53A, closd rod group 60, specifically it includes: a holder 54A, in be provided with an axis hole 541A; One body 55A and holder 54A link, and it is axially arranged with a conical chamber 52A coaxial with holder 54A, then are provided with a primary fire pipe road 56A and number stove fire pipeline 57A at conical chamber 52A periphery; Close sub-53A, coincideing is contained among the conical chamber 52A, as shown in Figure 7, closes sub-53A week side and is provided with female fire hole 531A, number stove fire hole 532A.As Fig. 5, shown in Figure 8, a closd rod group 60, in the present embodiment, it is used for pushing tow and rotation is closed sub-53A and carried out suitable angle adjustment, but therefore do not limit its manner of execution, can adopt the gas opening structure (belong to prior art, do not repeat them here) of direct rotation yet.Yet above-mentioned two kinds of gas switch opening ways all need an additional microswitch 95, the configuration scenario of microswitch 95 as shown in figure 14, it utilizes a cam 89 action triggers on the closd rod group 60, opens and closes power supplys for as shown in Figure 2 IC control module 84.The difference part of the present invention and known gas switch is, on each gas switch body 55A, laterally be provided with one and be communicated with perforation 63 outside and that communicate with the conical chamber 52A of Switch main body 55A inside, perforation 63 is connected with the other end of female burning things which may cause a fire disaster copper pipe 39, closes relative 63 the position of boring a hole of sub-53A periphery and also is provided with a through hole 66.Shown in Figure 10 A, Figure 10 B, with present embodiment, the cross section of through hole 66 does not communicate and design a little backward with perforation 63 usually, at rotation 63 communicate with through hole 66 (shown in Figure 11 A, Figure 11 B) that then bore a hole after the suitable angle, mandatory declaration be, during manufacturing, if the through hole 66 that closes sub-53A is deviation to some extent, and depart from through hole 66 position (shown in Figure 12 A) that local or whole communication bores 63 take place, but since primary fire pipe road 56A not yet with close the female fire hole 531A of sub-53A and communicate, therefore do not have the situation that gas leaks at ordinary times, shown in Figure 12 B yet.On the other hand, when user's push switch knob rotates, the female fiery gas source that transports by female burning things which may cause a fire disaster copper pipe 39 of pressure differential disc, then can be via perforation 63, through hole 66 flows into and closes among the sub-53A, as Fig. 5, shown in Figure 6, closd rod group 60 is by first gas-tight ring 601 of front end at this moment, corresponding second gas-tight ring 602 that closes the inner taper hole 59A of sub-53A position of arranging in pairs or groups again, utilize first, two gas-tight rings 601,602 are closing the inner sealing room 69 that forms of sub-53A when flat, the perforation 63 of the by chance corresponding gas switch body of sealing room 69 55A, make of the transmission of the female fiery gas of pressure differential disc, by perforation 63 via copper pipe 39, through hole 66 flows in the sealing room 69 that closes son.Therefore pass through the design of first and second gas-tight ring 601,602 of sealing room 69 2 sides, female fiery gas is blocked at ordinary times, do not communicate with the primary fire pipe road 56A of gas switch.

Via above-mentioned design, gas switch control system of the present invention and device thereof, when opening such as Fig. 8, shown in Figure 9, the closd rod group 60 of gas switch is revolved or is rotated forward because of the pressure of switching knob and passes, make the female fiery gas that is closed room 69 sealings break away from the state that seals taper hole 59A because of second gas-tight ring 602, flow into voluntarily and close among female fire hole 531A of sub-53A, and then the primary fire pipe road 56A of outflow Switch main body 55A, flow out again burner outside with one trigger igniting induction installation 80 and trigger igniting induction operation, as shown in Figure 1, it is the electric power source 81 of a dry cell batteries that triggering igniting induction installation 80 includes one, in fact also can connect a rectifier and suitable home-use AC power; One discharging rod 82; One inductive needle 83 and an IC control module 84.After in case the discharging rod 82 of gas switch is lighted female fire, be positioned at 83 other of inductive needles of burner and produce signal notice IC control module 84 at once, and the plug spare 36A shutoff valve port 38A of brake pressure difference dish inside flows in the negative pressure room to interrupt gas immediately, so, the film 34A of pressure differential disc makes Valve plug 33A by the valve 25 (as shown in Figure 3) of drawing and then unlatching gas shunt conduit 20A because of negative pressure disappears, make a large amount of gas moment flow into the gas inlet 51A of gas switch and even inner and then flow out burner and of the inferior sequential mode mixed combustion of the female fire of gas, wholely finish the burner operation of burning with several no time differences via the gas tube connector 40A of correspondence.Therefore, the present invention makes female fiery gas be introduced into the mode that gas switch is lighted and the activation of perception synchronously stove fire gas follows up immediately with the independent tubes design, and the reaction of the sensitive no time difference of collocation pressure differential disc makes burner burning operation of the present invention very quick.

Relatively, when the user closes burner or suffers from the undesired situation of burner when flame-out, then inductive needle 83 can be sensed flame at once and not have (can not arranged the stand-by period as the thermocouple induction temperature), send signal notice IC control module 84 immediately and the plug spare 36A of pressure differential disc is upspring again, the gas source is flowed in the negative pressure room once more, and the film that makes pressure differential disc is replied equilibrium condition, make Valve plug 33A block the valve 25 of gas shunt conduit 20A again, no matter be stove fire gas (because of Valve plug 33A ejects sealing shunt conduit valve 25) or female fiery gas source (because of being closed in the sealing room 69) this moment, can not flow out burner, reach and effectively finish the effect of cutting off gas immediately.

Again as shown in figure 13, schematic diagram for the present invention's second preferred embodiment, the difference of itself and the foregoing description is that the female fiery gas of the negative pressure of pressure differential disc is to make in the mode of external copper pipe 90, different with the built-in mode of gas channel 35A of the foregoing description, all the other functions are all consistent, do not repeat them here.

In sum, the present invention utilizes the female fiery gas drainage design of the independence of gas switch, make female fiery gas via the design of perforation with through hole that closes son and sealing room, the pressure differential disc and the IC control module of the brand-new configuration of collocation, improving known gas switch fully, to utilize magnetic valve and thermocouple to open and close gas burner induction speed slow, the shortcoming of poor stability.
