The adjusting of the anglec of rotation of rotary body 61 is undertaken by the firepower adjusting knob 7 on every side that is arranged on a fire button 5.As shown in Figure 4, firepower adjusting knob 7 is on the base portion 70a by the hollow cylinder shape cover 70b of ring-type to be installed and to constitute.
The end pitch in accordance with regulations of the 1st inner passage 11a side of firepower adjusting knob 7 is provided with cutting, and this cutting part 71 is with gear 72 engagements chimeric with an end of the rotary body of giving prominence to from part 2 11b 61.Thus, the rotary body 61 and the rotary manipulation of firepower adjusting knob 7 are synchronously rotated.
Here, when gas burner 23a, 23b ignition operation, for reliably to fuel gas igniting, preferably to gas burner 23a, 23b supply with firepower that fuel gas makes gas burner 23a, 23b for example for strong or in.
In addition, consider security, make the discharge cell action in order not make mistake touch point fire button 5 such as children, so-called children's locking mechanism can be set, if but lock operating portion then can cause cost to increase because children's locking is provided with children in addition.
With reference to Fig. 2 to Fig. 6, in the present embodiment, when forming cam path 73 from the inner peripheral surface in the place ahead of the outstanding firepower adjusting knob 7 of front panel 24, the outer peripheral face of the some fire button 5 that fore-and-aft direction moves the firepower adjusting knob 7 of hollow in is provided with and constitutes the right the 1st with cam path 73 and protrude sheet 51 to constitute the pressure rotating mechanism.In this occasion, the 1st protrudes sheet 51 is being installed in the radial hole 52 of the outer peripheral face that is arranged on a fire button under the state of the radial outside application of force by spring 53.
Thus, for the igniting of gas burner 23a, 23b, from closing valve position will put fire button 5 and be pressed into operation the time, then the 1st protrudes sheet 51 and becomes driving link, will be formed with the position that rotates to regulation as the firepower adjusting knob 7 of the cam path 73 of driven member.
In this occasion, owing to utilize the operation that is pressed into of some fire button 5 that firepower adjusting knob 7 is rotated,, can make simplifying the structure of controller for gas so for example do not need that increasing contracts and be located at the application of force of the spring 17 between a fire button 5 and the part 1 11a.
In addition, the operation that is pressed into that forms along with a fire button 5 of the wall face height of cam path 73 reduces from a side towards the opposing party.From close valve position carry out a fire button 5 be pressed into operation the time, then along with the moving an of fire button 5, the 1st protrudes sheet 51 is accommodated in the above-mentioned hole 52, arrives from cam path 73 to par 74 that length direction extends.
When further being pressed into operating point fire button 5, then being housed in the 1st in the above-mentioned hole 52 and protruding sheet 51 and 74 move and arrive ignition location along the par.Then, make discharge cell action, after gas burner 23a, the 23b igniting, when removing the pushing of some fire button 5, then put fire button 5 and under the application of force of spring 5c, arrive and drive valve position by heart type cam mechanism 5b guiding.
With to drive valve position corresponding, form and 74 conplane rotations guiding roads 75, par at the inner peripheral surface of firepower adjusting knob 7, firepower adjusting knob 7 is along rotation guiding road 75 to clockwise direction or rotation counterclockwise freely.
In this occasion, the 1st protrusion sheet 51 that is housed in the hole 52 does not engage with cam path 73.And, rotary body 61 rotation, so that when firepower adjusting knob 7 rotated toward the clockwise direction, gas flow was reduced, when counterclockwise rotating, gas flow increases.
In this occasion, because the rotating range to firepower adjusting knob 7 limits, in case will be arranged on firepower adjusting knob 7 base portion 70a periphery wall protuberance (not shown) towards rotation counterclockwise up to be arranged on stove 21 on brake component (not shown) engage till, then to be configured to each elongated slot 62b, 62c of the 2nd, the 3rd and the 4th, 62d consistent with each communication channel 15b, 15c, 15d respectively for rotary body 61, makes the gas quantity that flows to combustion gas outflow portion 16 become maximum.
On the other hand, the 1st elongated slot 62a only with the 1st communication channel 15a consistent location on, the rotation brake spare 76 that will contact with the protuberance 56 on the end that is arranged on a fire button 5 is arranged in the rotation guiding road 75 (with reference to Fig. 6).
Thus, driving valve position, firepower adjusting knob 7, only in the gas flow that flows to combustion gas outflow portion 16 firepower of gas burner 23a, 23b that is little little firepower, the gas flow that flows to combustion gas outflow portion 16 for the firepower of hour gas burner 23a, 23b when maximum is the such firepower adjustable range of strong strong firepower rotation freely, an end in rotation guiding road 75 and rotation brake spare 76 formation rotating range limiting mechanisms.
At this, regulate for cooking person carries out firepower easily, for example also can make firepower at gas burner 23a, 23b and be weak and in the position send card tower sound.
As shown in Figure 3, protrude sheet 51 with respect to the 1st, be provided with the 2nd at the outer peripheral face of a fire button 5 and protrude sheet 54.This occasion than the 2nd little protrusion sheet 54 of the 1st protrusion sheet 51 diameters, is being installed in the radial hole 55 of the outer peripheral face that is arranged on a fire button 5 under the state of the radial outside application of force by spring 56.
In addition, only on the assigned position in rotation guiding road 75, form respectively and can protrude the 1st and the 2nd recess 77,78 radially that sheet 54 engages with the 2nd.For example, firepower adjusting knob 7 is rotated towards counter clockwise direction from minimum discharge (in this occasion, the firepower of gas burner 23a, 23b is little), in case the 2nd protrusion sheet 54 engages with the 1st recess 77 then sends card tower sound.In this occasion, except that the 1st elongated slot 62a, the 2nd elongated slot 62b is consistent with the 2nd communication channel 15b, has increased the gas flow that flows to combustion gas outflow portion 16, and gas burner 23a, 23b burn down.
Further firepower adjusting knob 7 is rotated towards counter clockwise direction, engage, then send card tower sound in case the 2nd recess 78 and the 2nd protrudes sheet 54.In this occasion, except the 1st and the 2nd elongated slot 62a, 62b, the 3rd elongated slot 62c is consistent with the 3rd communication channel 15c, increases the gas flow that flows to combustion gas outflow portion 16, during the firepower of gas burner 23a, 23b becomes.
Thus, needn't be because of the other setting operation portion of children's locking mechanism, push also towards ignition location and can not move from closing valve position even will put fire button 5, form the latched position that the ignition mechanism of gas burner is failure to actuate.
But, the occasion of children's locking mechanism is set, preferably can make cooking person discern children's lock function easily and work.In the present embodiment, as shown in Figure 7, when the top of the firepower adjusting knob 7 that enters cooking person's sight line easily is provided with the 7a of window portion, on the assigned position of rotary body 61, put on red-label.And in case firepower adjusting knob 7 rotates to latched position, then this red-label is just in time consistent with the 7a of window portion.
Below, utilize gas burner 23a that the action of controller for gas 1 of the present invention is described.When pass valve position shown in Figure 2 is pressed into operating point fire button 5, then make 7 rotations of firepower adjusting knob by the 1st effect of protruding sheet 51 and cam path 73.
In this occasion, rotary body 61 is rotated by gear 72, in this position, 1st, each elongated slot 62b, 62c of the 2nd and the 3rd, 62d are consistent with the 1st, the 2nd and the 3rd each communication channel 15b, 15c, 15d respectively, and the fuel gas of the gas flow of the firepower that makes gas burner 23a in being flows to combustion gas outflow portion 16 (with reference to Fig. 6 (d) and Figure 11).
When being pressed into of continuation point fire button 5 operated, then as shown in Figure 8, action bars 4 is pushed towards the rear by pressing lever 5a, main valve is driven valve, make valve body 32 arrive the ignition location that pushed away absorption sheet side.
After arriving ignition location, gas burner 23a is carried out ignition operation by discharge cell.Then, when being arranged on the flame that flame detecting element 26 (with reference to Fig. 1) on the gas burner 23a limit detects gas burner 23a, then magnetic valve 3 is undertaken excitatory by the signal from the control unit and keeps opening the valve state.
In case after having confirmed gas burner 23a igniting, remove pushing of some fire button 5, then put fire button 5 and arrive the valve position of opening shown in Figure 9 by heart type cam mechanism 5b guiding.Driving valve position, when main valve kept out valve under the pushing effect of action bars 4, firepower adjusting knob 7 rotated freely in the firepower adjustable range.
And, in order to strengthen the firepower of gas burner, from the moderate heat position, will be arranged on firepower adjusting knob 7 base portion 70a periphery wall protuberance towards rotation counterclockwise up to be arranged on stove 21 on brake component engage till, then each elongated slot 62b, 62c of the 2nd, the 3rd and the 4th, 62d are consistent with the 2nd, the 3rd and the 4th each communication channel 15b, 15c, 15d respectively, and the firepower that makes gas burner 23a is that the fuel gas of strong gas flow flows to combustion gas outflow portion 16 (with reference to Fig. 6 (e) and Figure 10).
On the other hand, in order to reduce the firepower of gas burner 23a from moderate heat, with firepower adjusting knob 7 rotation toward the clockwise direction again, up to the 2nd protrude sheet 54 engage with the 1st recess 77 send card tower sound till, then each elongated slot 62a, 62b of the 1st and the 2nd are consistent with each communication channel 15a, 15b of the 1st and the 2nd respectively, and the firepower that makes gas burner 23a is that the fuel gas of weak gas flow flows to combustion gas outflow portion 16 (with reference to Fig. 6 (c) and Fig. 3).
Then, firepower adjusting knob 7 rotated toward the clockwise direction up to the 1st protrude sheet 51 and till rotation brake spare 76 contacts, then only the 1st elongated slot 62a is consistent with the 1st communication channel 15a, and the firepower that makes gas burner 23a is that the fuel gas of little minimum gas flow flows to combustion gas outflow portion 16 (with reference to Figure 12 and Fig. 6 (b)).
With the occasion of gas burner 23a fire extinguishing, in the time of will putting fire button 5 and rearward be pressed into operation from driving valve position, then heart type cam mechanism b resets, point fire button 5 is subjected to the application of force of spring 5c, retreats the pass valve position of giving prominence to from firepower adjusting knob shown in Figure 27.
In this occasion, removed the action bars 4 that pressing lever 5a pushes, be subjected to the application of force of spring 34 and backward directions move, close main valve.In case main valve is closed, then the supply of the fuel gas of gas burner 23a is stopped and putting out a fire.Recognize that by flame detecting element 26 flame extinguishes when control module, then close valve magnetic valve 3.
At last, closing valve position, firepower adjusting knob 7 is surpassed the firepower adjustable range and when clockwise direction rotate along cam path 73, then the 1st protrudes sheet 51 and engages with the 73a of wall portion of cam path 73, puts fire button 5 can not push, and becomes children's lock-out state.

The 2nd protuberance 502 form a fire button 5 drive valve position, in case when firepower adjusting knob 7 rotated toward the clockwise direction, then with the 1st protuberance 501 butts (with reference to Figure 15 (a)).In this occasion, only the 1st slotted hole 62a of rotary body 61 is consistent with the 1st communication channel 15a.Therefore, the 2nd protuberance 502 plays as the function to the rotation brake spare that flows to the firepower adjusting knob 7 that minimum gas flow that gas-flow goes out portion 16 sets.
With firepower adjusting knob 7 when the position of the 2nd protuberance 502 and the 1st protuberance 501 butts is further rotated toward the clockwise direction, the 2nd protuberance 502 on the inclined plane 501a of the 1st protuberance 501, slide (with reference to Figure 15 (b)) then.
In this occasion, will put fire button 5 and be pressed into towards the place ahead, when the 2nd protuberance 502 passes through on the inclined plane 501a of the 1st protuberance 501, heart type cam mechanism 5b reset (with reference to Figure 15 (c)).In this occasion, some fire button 5 is subjected to the application of force of spring 5c and the pass valve position (with reference to Figure 15 (d)) of reentry point fire button 5.
Thus, except that be pressed into operating point fire button 5 make gas burner 23a, 23b the fire extinguishing, because each protuberance 501,502 of the 1st and the 2nd becomes the pressure travel mechanism of a fire button 5, with firepower adjusting knob 7 towards rotation can make the fray-out of flame of gas burner 23a, 23b once the side, so can improve the ease of use of Gas appliance.
But, in this 1st and the 2nd embodiment, make firepower adjusting knob 7 and rotary body 61 rotation synchronously by gear mechanism 71,72, but be not limited thereto, also can use belt mechanism etc. that rotary body 61 and firepower adjusting knob 7 are rotated synchronously.
In addition, also can as shown in figure 16 motor 8 be set, make gear 81 and rotary body 61 engagements on the rotating shaft that is installed in this motor, by motor 8 rotary manipulation rotary bodies 61.
Structure yet shown in Figure 17, the occasion in that operation firepower adjusting knob 7 sharply reduces gas flow does not make gas burner 23a, 23b flame-out.In this occasion, the 2nd inner passage 12b between gas flow outlet 14 and the flow control valve 6 is separated by the barrier film 9 of spring 91 towards the gas flow outlet 14 direction application of forces, is provided with by-pass 93 between the gas outlet 16a of air cavity 92 that separates and combustion gas outflow portion 16.
Sharply reducing the gas outlet 16a that occasion produced of gas flow and the pressure official post barrier film 9 of gas flow outlet 14 moves, supply with gas outlet 16a by the fuel gas that is trapped in the air cavity 92 by by-pass 93, can prevent stopping working of gas burner 23a, 23b.
And, as shown in figure 18, also can the consistent control valve 200 of gas pressure that make fuel gas be set between gas flow outlet 14 and flow control valve 6, in addition, also can as shown in figure 19 1 magnetic valve 210 be set in addition except that magnetic valve 3 between gas flow outlet 14 and flow control valve 6.
