First and second flow control valves 10,11 and an operating parts 13 are connected and are controlled.This operating parts 13 comprises an executive component 14 and follows a lobe plate 15 of these executive component 14 actions.From the outstanding pin P1 of each flow control valve 10,11, P2 be provided be used for lobe plate 15 on cam path 16,17 engage.Under this structure, depend on the operational ton of executive component 14, first and second flow control valves 10,11 with respect to the valve opening 6a that is arranged in each gas passage 6,7, and the position of 7a can be regulated, thereby can control and infeed each burner 1a, the fuel among the 1b (coal gas).
In more detail, first flow control valve 10 is provided with an aperture 10a, an one throttling part 10b and a closed portion 10c, aperture 10a is used for determining minimum amount of restriction, throttling part 10b is used for regulating several 6a of valve in the gas passage 6 and the flow between the first flow control valve 10, and the gas passage 6 that closed portion 10c communicates with big capacity burner 1a matches and is used for cutting off the fuel that infeeds among the big capacity burner 1a.Second flow control valve 11 is provided with and is used for determining that the aperture 11a of minimum amount of restriction and several 7a of valve that are used for in the gas passage 7 match to regulate the throttling part 11b of flow.
Above-mentioned main valve 12a is installed on the valve rod 22, and valve rod 22 passes gas passage 9, and its rearward end is placed in the place ahead of button ignition switch 20.When valve rod 22 when the start position A of button ignition switch 20 shifts terminal position B onto, main valve 12a opens.Electromagnetic valve 12b also is opened by the promotion of valve rod 22 front ends.When the electric power as the thermocouple of flame detector 21 surpassed predetermined value, electromagnetic valve 12b was opened.
The engaging mechanism of the motion below label 23 expressions are carried out.That is to say that when pressing elastic force that button ignition switch 20 overcomes backspring 24, being pressed onto terminal position 13 from start position A, when then decontroling button, button ignition switch 20 is bonded on centre position C.When arriving off-position D when pressing button ignition switch 20 once more, just from the engagement state of centre position C throw off, so under the thrust of backspring 24, button ignition switch 20 is got back to start position A.Engaging mechanism 23 comprises a cam bit 26 and a joint element 27, this cam bit 26 has a cam path 25, and be arranged on the button ignition switch 20, the bottom of joint element 27 is supported in the guide cylinder 18 that resin makes swingably, and the front end of joint element 27 engages with cam path 25 by the side channel 18a in the guide cylinder 18.The front end of joint element 27 fits by the bottom surface of a hairspring 19 with cam path 25.
As shown in Figure 6, cam path 25 is cannelures, and it is by first to the 3rd slot part 25a of step, 25b, and 25c and the 4th slot part 25d constitute.The other point of contact of first to the 3rd slot part is O, P, and Q and R, the start position of these points and button ignition switch 20, terminal position B, centre position C is corresponding with off-position D, and the 4th slot part 25d is point of contact R and O.When button ignition switch is shifted onto terminal position B from start position A, joint element 27 is because the relative motion of itself and cam bit 26 moves to a P from an O via the first slot part 25a.When button ignition switch 20 under the effect of backspring 24 when terminal position B returns, joint element 27 moves to the corresponding position Q with centre position C via the second slot part 25b, and is bonded on the C of centre position.Touch the button 20 the time when pressing, joint element 27 moves to the corresponding position R with off-position D via the 3rd slot part 25c again.Subsequently if unclamp button ignition switch 20,27 of joint elements turn back on the A of start position via the 4th slot part 25d.
The elastic force that overcomes backspring 24 with button ignition switch 20 when start position A is pressed onto terminal position B, main valve 12a just opened before button ignition switch 20 arrives centre position C, when button ignition switch 20 arrives terminal position B, electromagnetic valve 12b is open, and is connected in the switch S closure in the igniter (not shown) operating circuit.When arrive at button ignition switch 20 terminal position B near the time when unclamping button ignition switch 20, button 20 just is bonded on the C of centre position, and unclamps the pushing to electromagnetic valve 12b, but main valve 12a stays open.When pushing button ignition switch 20 once more, unclamp with engaging of centre position C, when button 20 was got back to start position A, main valve 12a removed open mode and closes.
Distance between off-position D and the start position A is nearer than the distance between it and the terminal position B, and therefore when pushing button ignition switch 20 once more, switch S is not worked.
The executive component 14 of above-mentioned formation operating parts 13 is made a lever, and the one end is supported on the upper surface of valve chamber 3 rotationally.Be arranged on the side that the one end is supported on valve chamber 3 rotationally by the lobe plate 15 of executive component 14 operation.The projection 15a that gives prominence to outside lobe plate 15 is bonded among the hole 14a of executive component 14 insertedly, and therefore along with the motion of executive component 14, cam bit 15 can be swung around axle 15e.
According to this configuration, when the lobe plate 15 that constitutes operating parts 13 was in the throttle position of second flow control valve 11, if button ignition switch 20 is shifted onto terminal position B from start position A, second flow control valve 11 just is pushed to opened side.
At this moment, even the pushing button, first flow control valve 10 is not opened yet and is kept closing.
In this embodiment, lobe plate 15 is provided with one and receives piece 15d, it is facing to the motion track of projection 20a outstanding from button ignition switch 20, and their structure makes when projection 20a withstands reception piece 15d, and cam bit 15 is swung and made second flow control valve 11 towards its lateral movement of opening.
Above-mentioned electromagnetic valve 12b is contained in the gas passage, by it being inserted in the resinous cylinder 29 as shown in Figure 8.One end of this cylinder 29 has an aperture 29a, and valve rod 22 inserts in this aperture.Because the front end of valve rod 22 is installed by this aperture 29a, so the front end face of valve rod 22 is facing to electromagnetic valve 12b.Front end at valve rod 22 is provided with a junction piece 22a, and it prevents that valve rod 22 from skidding off aperture 29a.One spring 31 is set between the end of spring base 22b on the valve rod 22 and cylinder 29.
The following describes the operation of apparatus of the present invention.
When executive component 14 is in position shown in Fig. 9 (a), lobe plate 15 is in the position shown in Figure 11 (a), therefore, first and second flow control valves 10,11 make gas passage remain on the state of standard-sized sheet, knot is looked into, and shown in Figure 10 (a), the fuel that is in maximum infeeds the state among capacity burner 1a and the low capacity burner 1b.When executive component 14 moves to position shown in Fig. 9 (b) subsequently, lobe plate 15 promptly moves to the position shown in Figure 11 (b).Shown in Figure 10 (b), second flow control valve 11 keeps standard-sized sheet, and low capacity burner 1b is in the state that infeeds maximum fuel.First flow control valve 10 then makes gas passage 6 throttlings, and the fuel that infeeds big capacity burner 1a is by the gap between aperture 10a and valve opening 6a and the first flow control valve 10, and the flow that maintenance limits.
When executive component 14 moves to position shown in Fig. 9 (c) subsequently, lobe plate 15 will turn to the position shown in Figure 11 (c).Shown in Figure 10 (c), second flow control valve 11 keeps standard-sized sheet, and small container burner 1b is in the state that infeeds maximum fuel.First flow control valve 10 is then closed gas passage 6 with its closed portion 10c.Thereby cut off fuel supply to big capacity burner 1a.
Subsequently, when executive component 14 moves to position shown in Fig. 9 (d), lobe plate 15 will move to the position shown in Figure 11 (d) thick line.Shown in Figure 10 (d), gas passage 7 is by 11 throttlings of second flow control valve, thereby is in the state of the fuel limit of low capacity burner 1b in the limit amount that is infeeded by the aperture 11a that is arranged in second flow control valve 11.The fuel that infeeds big capacity burner 1a still is cut off.
The ignition operation of apparatus of the present invention will be described below.When the elastic force that overcomes backspring 24 button ignition switch when start position A shifts terminal position B onto, before just will arriving centre position C, main valve 12a opens, and opens electromagnetic valve 12b near terminal position B the time.The switch S that is connected in the igniter (not shown) function circuit is closed.No matter where executive component is in, and fuel is fed among the low capacity burner 1b at least, and fuel is by the spark ignition of igniter (not shown).
When discharging button ignition switch 20 subsequently, under backspring 24 effects, button ignition switch is got back in the A process of start position, and button ignition switch 20 is engaged mechanism and is bonded on centre position C, and main valve 12a stays open in this position.
In the time will closing fire extinguishing, can push button ignition switch 20 again, the joint of button ignition switch 20 will get loose, and turn back to start position A.Thereby close main valve 12a, stop supplies fuel.
When executive component 14 is in the position shown in Fig. 9 (d), when lobe plate 11 (d) was in position shown in Figure 11 (d), second flow control valve 11 will be to gas passage 7 throttlings, shown in Figure 10 (d).Therefore fuel is fed among the low capacity burner 1b via the aperture 11a in second flow control valve 11 with throttle.Under this throttle, for the electric power that increases sharply and produce as the thermocouple of flame detector 21, thereby the ignition operation that makes electromagnetic valve 12b open and carry out success rapidly, fuel quantity is inadequate.Therefore, when executive component 14 is in above-mentioned state, if operation button ignition switch 20 just with button ignition switch 20 when start position A shifts terminal position B onto, just following situation can take place.Just, projection 20a promotes to be arranged on the reception piece 15d on the lobe plate 15, thus make lobe plate 15 from evolution shown in Figure 11 (d) to the position shown in Figure 11 (c).As a result, shown in Figure 10 (c), second flow control valve 11 is transformed into full open position and first flow control valve 10 remains closed.Adopt this structure, the fuel (coal gas) that always can be implemented in maximum infeeds under the state of low capacity burner 1b and lights a fire.
In this example, be designed to a kind of like this structure, if second flow control valve 11 is in state to gas passage 7 throttlings when promptly lighting a fire, then second flow control valve 11 can be switched to full open position and carries out igniting.But,, also be enough if infeed with the required minimum fuel of successfully lighting a fire for low capacity burner 1b.In this example, only be that the position arrangement one-tenth of second flow control valve is opened fully.
Behind ignition operation, second flow control valve 11 keeps just being in the state of all opening as ignition operation.Even after ignition operation was finished, operating parts still is in one stayed open down second flow control valve.Therefore, even under the bigger situation of the difference of the difference of the quantity combusted in different burners or flame size, do not reduce the therefore misjudgment that can not put out a fire rapidly finishing igniting after-combustion amount.
For throttling after igniting or minimizing infeed fuel quantity among the low capacity burner 1b, executive component 14 can turn back to the position shown in Fig. 9 (d).
In Figure 12, curve X representative infeeds the restriction characteristic of the fuel among the big capacity burner 1a, and curve Y representative infeeds the restriction characteristic of the fuel among the low capacity burner 1b.
Below an example is described, in this example, separately be provided with gas passage 6,7, first and second flow control valves 10 of being with gas exit 4,5 respectively.11 are connected in the passage respectively.But to shown in 14 (d), following modification example also can be carried out same control as Figure 13 and Figure 14 (a).Just, in a single gas passage 30, the gas exit 4,5 that is connected with big capacity burner 1a and low capacity burner 1b respectively is set.Holistic clavate valve body 32 is set in gas passage 30, and it has the first flow control valve 10 and second flow control valve 11.In corresponding figure, be marked with same label with element same in the above-mentioned example or the element that plays same purpose.
In more detail, the first flow control valve is made of a dilation, and it matches with the O shape circle valve seat 30b of the bottom that is located at valve chamber 3.Second flow control valve 11 is made of the flange portion that the second gas exit 32b slightly downstream forms in the valve body 32 of side.
Upstream side at gas passage 30 is provided with a valve opening 30a, and it matches with second flow control valve 11 in being arranged on valve body 32; Also have a gas exit 5, it is positioned on the wall of the valve opening 30a that is partial to the downstream a little, and is connected with low capacity burner 1b; Also be provided with O shape circle valve seat 30b, it is positioned at slightly downstream side of gas exit 5, and matches with first flow control valve 10; Also have gas exit 4, it is located in the wall of the O shape of side circle valve seat 30b slightly downstream and with big capacity burner 1a and is connected.
The leading section of valve body 32 is provided with the first gas exit 32a, and it determines the minimum throttling of low capacity burner, and always remains on open mode, also has the second gas exit 32b, and it matches with the valve opening 30a and second flow control valve 11 and opens and closes.
If make valve body 32 with the situation that links as the lobe plate 15 of aforesaid operations spare 13 under, mobile a little, and second flow control valve 11 is in throttle, then when operation button ignition switch 20, just with button ignition switch 20 when start position A moves to terminal position B, second flow control valve 11 is transformed into full-gear.
In this remodeling embodiment, a thermocouple is as flame detector 21, and the electric power that thermocouple produces works to electromagnetic valve 12b, and it is opened.But, for example also can be with a flame rod as flame detector 21, the electric power that makes thermocouple produce is higher than a predetermined value, can supply an electric energy to electromagnetic valve and go to open it.
In addition, in the above-described embodiments, first flow control valve 10 is arranged to identical with the glide direction of button ignition switch with the glide direction of second flow control valve 11.Be that they always do not require identical entirely.
Figure 15 to 24 shows another embodiment of the present invention.To be described below.In relevant figure, be marked with same label with same element of above-mentioned example or the element that plays same purpose.Below structure and the foregoing description that what there is no is different especially.That is to say that in the embodiment with Fig. 1 to 12 had first and second flow control valves 10,11 with spline structure, second flow control valve 11 was operated part 13 and opens gradually, from minimum flow position to progressively increasing the quantity combusted that is fed to the low capacity burner 1b.After second flow control valve 11 was opened fully, first flow control valve 10 was opened gradually and is progressively increased the fuel quantity infeed the big capacity burner 1a from closing position.
But in this embodiment, valve chamber 3 is provided with tank bracket plate 3a, and operating parts 13 is formed by this frame plate 3a with by the executive component 14 that flame board is supporting rotationally.From the outstanding pin P of flow control valve 10,11
1, P
2Engage with the cam path 16,17 that is formed on the frame plate 3a.In this structure, first and second flow control valves 10.11 with respect to the valve opening 6a that is respectively formed in the gas passage 6,7, and the position of 7a is adjusted according to the operational ton of executive component 14, infeeds burner 1a so can control, the fuel quantity among the 1b.
In more detail, obviously as seen, frame plate 3a covers that part of outside that flow control valve 10,11 is set in the valve chamber 3 by metallic plate bending to form from Figure 20.Left surface part 3a-1 along valve chamber 3 left sides is provided with a cam path 16, and it engages with the pin P1 that gives prominence in first flow control valve 10 outsides.Right surface portion 3a-3 along the right side of valve chamber 3 is formed with a cam path 17 (as shown in figure 22), and it engages with the pin P2 that gives prominence in second flow control valve, 11 outsides.Label 3a-2 represents along the front portion of the front surface of valve chamber 3.From Figure 20 to 23 obviously as seen, executive component 14 is by respectively along left surface part 3a-1, three part 14a of front part 3a-2 and right surface portion 3a-3,14b and the 14c formation of frame plate 3a.The sidepiece 14b of executive component 14 is supported on rotationally by axle 40 on the front surface portion 3a-2 of frame plate 3a, can do upper and lower swing around axle 40.With pin P1, the groove 33,34 that P2 engages is respectively formed at along the part 14a of the executive component of the left-hand face part 3a-1 of frame plate 3a and right lateral surface part 3a-3, on the 14c.
Then, at pin P1, when P2 was mobile simultaneously, the 16a of hopper portion that inclines was corresponding mutually with horizontal slot part 17b, and space segment 16b is corresponding mutually with the 17a of tipper department.
As the embodiment of explanation in front, open to keep electromagnetic valve 12b as the electric power of the thermocouple of flame detector 21 in order to increase sharply, low capacity burner 1b by the situation of throttling under, the fuel quantity during igniting is with deficiency.Therefore, in this embodiment, fork 35 a usefulness axles 35c is supported on the valve chamber 3 rotationally, between the projection 20a that protrudes in projection 14d outside the executive component 14 and button ignition switch 20, make that an end 35a of fork 35 is relative with projection 14d, and other end 35b is relative with projection 20a.

In Figure 18, label 37 is illustrated in a groove that forms among the frame plate 3a.Rive that the part bending forms and protrude in that projection 14a outside the executive component 14 engages with groove 37 and the hunting range that limits executive component 14 by the part of executive component 14.
In Figure 15, label 76 expressions are communicated with the upstream side of second flow control valve 11 and the passage of gas passage 6.Label 38 was represented to get fire or transmit the start-up burner that flame makes big capacity burner 1a igniting.Label 39 expressions are located at the part of getting fire among the big capacity burner 1a.Label 35d is illustrated in a through hole that forms in the fork 35 among Figure 21, makes the front end of screwdriver can touch screw 41.Fixing in order to the cover piece 47 that covers gas passage by screw 41.
The connector that label 42 expression couples together the coil of electromagnetic valve 12b and thermocouple 21.As shown in figure 24, valve chamber 3 is provided with projection 43 and 44, and 10 outstanding pin P1 engage with projection 43 from the first flow control valve, has from second flow control valve, 11 outstanding pin P2 and projections 44 directly to close.These projections play pin P1, and the positioning action of P2 when frame plate 3a is placed on the valve chamber 3, helps pin P1, and P2 injects in the cam path 16,17 that forms among the frame plate 3a.
In Figure 20, an asessory shaft of label 45 expression forks 35.In other words, when this device is the left side burner of two kitchen range gas ranges or gas burner and right side burner when shared, can be by putting valve chamber 3 upside down conversely with the relation of the lateral position between button ignition switch 20 and the executive component 14.For example, require executive component 14 is placed on the outside of left burner 1 and right burner 1, perhaps require executive component 14 to be placed on the inside of left burner 1 and right burner 1, and, make first and second flow control valves 10 by executive component 14, when 11 throttling direction places same direction, can do following arrangement.Just, valve chamber 3 is put upside down, and an independent blocks frame plate 3a is set, and frame plate 3a is provided with the cam path 17 symmetrical with a cam path 16 of cam path shown in Figure 17 16 symmetries (being symmetry with respect to dotted line L) and and cam path shown in Figure 22 17.In addition, also be provided with another executive component 14 with executive component 14 symmetries shown in Figure 18 thick line, and with a fork 35 of fork 35 symmetries shown in Figure 21.Executive component 14 is supported among Fig. 8 on the axle 40 shown in the chain-dotted line rotationally, and fork 35 is being supported rotationally by asessory shaft 45.
According to a first aspect of the present invention, can obtain following advantages. That is: when button ignition switch from The start position is shifted terminal position onto, just with the button ignition switch operation of lighting a fire, and operation When element was positioned at the position of the second flow control valve throttling, executive component can guarantee necessarily Can be promoted by button ignition switch. In this operating process, second flow control valve is operated To opening side. Therefore, the igniting operation always can be in second flow-control of low capacity burner Valve is in to be finished under the state of opening. In addition, because super in the electric power of flame detector Be located at the upstream side of flow control valve when crossing predetermined value with regard to the electromagnetic valve that stays open, and Flame detector is in the position of being heated by the low capacity burner, so the quantity combusted that receives increases The added-time flame detector is just heated by the low capacity burner. Therefore, can reach fast the maintenance electricity The magnetic safety valve is opened the required electric power that is higher than certain certain value, and carries out successful igniting.
In addition, even behind the igniting end of operation, executive component still remains on and makes second flow Control valve stays open. Therefore, though the difference between strong burning and weak burning In the big situation, quantity combusted can rapid decrease yet, is judged as and does not put out so do not have mistake The possibility of fire.
According to a second aspect of the present invention, following advantage is arranged. When operating parts is in the throttling shape Attitude, and button ignition switch is shifted terminal position onto and is made second flow control valve by behaviour from the start position Workpiece moves to when opening side, and the first flow control valve remains closed. When second flow-control Valve is in when being lighted a fire on the position of operating parts throttling, does not supply fuel to big capacity combustion Burn in the device. Therefore, when igniting, do not consume excessive fuel, and, successfully light a fire Only increase minimum fuel, the shortcoming that does not exist the food that boils burning too to be heated.
