Explanation to the air inlet cross section and the cross section of giving vent to anger: as shown in figure 39, combustion gas air admission hole 73 is the air inlet cross section with the intersection of air inlet cross section regulating tank 74 (regulating tank that the abcdefga curve surrounds); As shown in figure 50, combustion gas air admission hole 73 is the air inlet cross section with the intersection of air inlet cross section regulating tank 94; The rest may be inferred for other.Regulating tank can be different shape.

The specific embodiment

Fig. 1 is described to be a kind of gas-cooker chief component overall construction drawing, and the fire hole that every circle burns on the head among the figure has several.Twisting worm screw 15 can drive and the 4th regulating sleeve rotation of enclosing burning head and the 3rd a circle burning band helical gear that links to each other or worm gear, the air inlet pipe that promotes to match with the regulating sleeve internal thread rises or descends, move up or down thereby promote to burn head, the operation principle that moves up and down sees Figure 17 to Figure 18 for details.Burn direct drive of a helical gear that links to each other with the 3rd circle when worm screw is rotated and burn a helical gear that a links to each other rotation, thereby make second circle burn head rising or decline with second circle.With the 4th circle burn the pitch of the internal thread of the corresponding regulating sleeve of head＞with the 3rd circle burn the pitch of the internal thread of the corresponding regulating sleeve of head＞with the pitch that second circle burns the internal thread of the corresponding regulating sleeve of head, therefore the 4th a circle burning rate of climb＞3rd encloses a burning rate of climb＞second and encloses a burning rate of climb.The shape and the up-down adjustment mode of burning head have a lot, see Fig. 2 to Figure 31 for details.Every circle burns the corresponding induction tunnel of head, the corresponding combustion gas nozzle of each induction tunnel.Flame and/or thermic load control device have a lot, see Figure 35 to Figure 71 for details.Each carriage is connected with master carrier (not drawing among the figure) among the figure, and the annexation of flame control device and carriage slightly.For making this figure clear, the location drawing of the perpendicular pole of a kind of adjustable support that only draws, adjustable support and operation principle thereof see Figure 72 to Figure 91 for details.

Fig. 2 to Fig. 7 is that burner burns first kind of structural representation, has omitted two broken circles among the figure, i.e. the outline line of fire hole circle.To be embedded in the fire hole circle that fire-resistant heat insulating material is made (the also available fire-resistant heat insulating material of this burning framework is made) on the burning framework that the cross section made from metal material is the U font, and the gap is shut with toothpaste or clay etc., has only a circle fire hole on the fire hole circle of this embodiment, aeroscopic plate is positioned at the mixed air cavity middle part on air inlet pipe top, and intersect at air inlet pipe axis and aeroscopic plate center.Its operation principle is: the combustion gas and the Air mixing gas (hereinafter to be referred as gaseous mixture) that flow into the gaseous mixture air inlet pipe from induction tunnel flow in the space of gaseous mixture frame and aeroscopic plate composition, flow to both sides again, respectively be divided into two strands again after flowing through aeroscopic plate, one flows into aeroscopic plate top, from each fire hole, flow out again, one continues to go in ring, and flows out from fire hole.The effect of aeroscopic plate is that the interior air-flow of gaseous mixture frame is evenly distributed, and makes the gaseous mixture speed that flows out from each fire hole close.If do not establish aeroscopic plate, then the gaseous mixture that flows out from the fire hole that faces air inlet pipe is fastest, the gaseous mixture speed that flows out from distance air inlet pipe fire hole farthest is the slowest, gas speed is inhomogeneous cause burning undesired, when the combustion gas nozzle velocity is maximum (during maximum heating load), the fire hole that has can take off fire, and when thermic load was reduced to a certain degree (in the scope at needs), the fire hole that has can tempering.This is an exemplary block diagram of burning head moving up and down.This kitchen range have a burning head need not move up and down, and then will burn head and induction tunnel and make integral body, and its structure chart is seen Figure 19 to Figure 20.Backstay is inserted in the carriage positioning hole corresponding, and its effect is to rotate when the burning head moves up and down Shi Burang burning head.Only having enumerated section among the figure is the burning head of U font, section be parabola shaped or the burning head of semicircular arc or other semiclosed pattern curves the rest may be inferred.

The described second kind of burning head of Fig. 8 to Figure 10 is made up of three parts, head cap burns by the annular that fire-resistant heat insulating material is made in first, crossing the section that the cutting plane in the axle center of this cap cuts out is the n font, this section can also be designed to parabola shaped, or semicircular arc, or a lot of shapes such as other semiclosed pattern curves, a kind of shape of only drawing among the figure, other shapes are by that analogy.Burn head cap top or side several fire holes are arranged; Second portion is that the main body that is made of metal is an annular burning base, and burning a base bottom has two backstays and a gaseous mixture air inlet pipe, and the gaseous mixture air inlet pipe is outer can screw thread; Third part is fan-shaped aeroscopic plate; Burn head cap and burn between the base, aeroscopic plate is installed between burning at the bottom of head cap and the burning headstock with glue or splicing clay.The front view of this burning head is identical with the Fig. 2 that has omitted fire hole circle outline line, and Fig. 9 and Figure 10 are the profiles in this burning two places.Only having enumerated section among the figure is the burning head of n font, and section is that the rest may be inferred for the burning head of semicircular arc or parabola shaped or other semiclosed pattern curves.

It is basic identical with second kind that described the third of Figure 11 to Figure 12 burns head, and just burning head cap and burning the position of installing between the base has any to change.

Described the 4th kind of burning head of Figure 13 to Figure 15 mainly made by fire-resistant heat insulating material, can increase its intensity as skeleton with metal material, or burning crown portion fire hole of increase endless metal thin slice (when burning fire hole in side endless metal thin slice on do not establish fire hole) corresponding with burning a fire hole, burning head is annular, its axial line is a vertical direction, the section that the cutting plane of a burning axial line cuts out is a square shape, or it is circular, or the shape of other sealings, burn crown portion or side several fire holes are arranged, burn a bottom gaseous mixture air inlet pipe and two backstays are arranged, connect with flexible pipe between gaseous mixture air inlet pipe and the induction tunnel, or the gaseous mixture air inlet pipe is inserted the induction tunnel inwall be slidingly connected, or induction tunnel is inserted the gaseous mixture air inlet pipe be slidingly connected, or increase another sleeve pipe and be slidingly connected by them.Only having enumerated section among the figure is the burning head of the degree of lip-rounding, section be circular or other close-shaped burning heads the rest may be inferred.

The described induction tunnel of Figure 16 (contain the band regulating sleeve and not with the induction tunnel of regulating sleeve) generally has only an elbow, and the needs of arranging sometimes can have two elbows, promptly in the axis horizontal face of induction tunnel one turn round, interior one of perpendicular turns round; One section of this induction tunnel vertical direction has screw thread to be convenient to link to each other with regulating sleeve.

In the described structure of Figure 17, the regulating sleeve outside is a helical gear, endoporus is a screw thread, and the screw thread of the first half is opposite with the thread rotary orientation of Lower Half, when rotary worm, helical gear then rotates, regulating sleeve then has relative rotation with induction tunnel and air inlet pipe, because the top and the bottom thread rotary orientation is opposite, so regulating sleeve is when descending or rising with respect to induction tunnel, air inlet pipe also descends or rises with respect to induction tunnel, thereby can allow the burning head move up and down.When using pan, each burning head drops on the carriage, and their horizontal level is identical.When with the curved surface pot, first to the 3rd circle (at least the first to second circle) can be burnt head toward raising, be beneficial to culinary art, the burning head that this time shift is got on has left carriage, supports by induction tunnel and regulating sleeve, does not rotate by it by backstay and locating hole.Worm screw is linked to each other with the axle of motor, then become manual adjustments and be motorized adjustment.Or the gear of regulating sleeve outside become spur gear, the gears engaged of on the axle of motor spur gear and regulating sleeve being installed also can realize motorized adjustment.Because of motorized adjustment just increases electronic part, very simple, so do not draw in addition.

Figure 18 burns head to move up and down second kind of structure chart, and different with Figure 17 is that helical gear can change worm gear into; The regulating sleeve bottom is a unthreaded hole, and induction tunnel outer wall top also is light pipe, does not produce during the regulating sleeve rotation to move up and down, and has only air inlet pipe to move up and down.Worm gear can change helical gear into herein.It is adjustable to have two circles to burn when adopting the scheme of Figure 11, because worm gear can not drive the 3rd helical gear or worm gear that burns head again, changes helical gear into and then can.

The described induction tunnel of Figure 19 to Figure 20 has two sections, and one section is horizontal direction, and one section is vertical aspect, and two sections junctions are elbow (being connected as a single entity).The induction tunnel of horizontal direction also can design elbow as the case may be, and promptly induction tunnel can have two elbows, and the center line of two elbows is not in same plane, and in mutually perpendicular two planes.One section center line of general each induction tunnel horizontal direction should be positioned on the same horizontal plane, and respectively burns crown face not in same horizontal plane, thereby a segment length of induction tunnel vertical direction has nothing in common with each other, and outermost one circle burns a section the longest of induction tunnel vertical direction of head.Also can the Design of length of each induction tunnel vertical direction is equally long, then the axis and the horizontal plane of flame and/or thermic load control device form an angle.The thermic load of burning head different owing to each, and therefore the induction tunnel thickness of each burning head is different.The β angle is arbitrarily angled among the figure, determines according to actual needs.The length of induction tunnel horizontal direction and hard Nogata to length determine according to actual needs.Induction tunnel is identical with existing induction tunnel with the part (end face) of combustion gas nozzle contact, can disclose Fig. 6 induction tunnel end face in 02138920.9 referring to Chinese patent application.It is in full accord that this burns among internal structure and Fig. 2 to Figure 14 burning.

The described burning of Figure 21 up-down adjustment structure adopts hydraulic regulation, active hydraulic stem applied thrust is allowed initiatively oil pressure rises in the hydraulic cylinder, and oil pressure promotes passive hydraulic stem and rises, and rises thereby make second and third circle burn head.When the active hydraulic stem was applied pulling force, initiatively oil pressure descended in the hydraulic cylinder, and oil pressure also descends in the then passive hydraulic cylinder, forced passive hydraulic stem to descend.Hydraulic pressure adopts prior art, and Figure 92 to Figure 95 has only done to briefly introduce to hydraulic pressure.Only active hydraulic cylinder front portion is linked to each other with oil pipe with passive cylinder lower among Figure 21, can also increase hydraulic oil pipe, be about to active hydraulic cylinder rear portion and link to each other with oil pipe with passive hydraulic cylinder top, passive like this hydraulic stem rises or descends and adds freely.

The described burning of a Figure 22 up-down adjustment structure adopts the screw thread selective gear to regulate, the twisting axis normal is in the conical gear handle of paper, can drive another conical gear rotation, thereby drive another coaxial roller gear rotation, drive other four gears rotation again, the axle of other four gears has screw thread, and these can rise or descend when rotating in the screwed hole of several fonts burning head brackets, thereby makes the burning head on the carriage rise or descend.On the burning head backstay is set, does not tilt when making it rising or decline.In addition, burn thread pitch on the corresponding gear shaft of head greater than burning thread pitch on the corresponding gear shaft of head with second circle with the 3rd circle, the amplitude of the 3rd rising is big when they rise.

The described burning of Figure 23 up-down adjustment structure adopts cam adjustment, and every circle burns corresponding two the identical cams of head, the shape of cam as shown in figure 24, its outline line is an Archimedes spiral, profile is a figure-six, the left and right sides is asymmetric.The helical pitch of two cams corresponding with the 3rd circle burning head is big among Figure 23, and the helical pitch of burning two corresponding cams of head with second circle is little, but their basic circle is identical.Waveform carriage 6 is orthogonal with camshaft 49 among the figure, burns a bottom backstay is set, and on the waveform carriage locating hole is set, held stationary when the burning head is moved up and down.

The described burning of a Figure 24 up-down adjustment structure also adopts cam adjustment, the waveform carriage 6 vertical with step carriage 52 determines to burn the home positions of head, promptly allow the burning head be in earlier in the same horizontal plane, the backstay that burns a bottom inserts in the locating hole of waveform carriage 6, makes held stationary (referring to Figure 32) when regulating.Clockwise shearing camshaft 49, then cam 50 promotes step carriages 52, and this carriage promotes the 3rd circle earlier and burns uply, promotes the 3rd circle again and burns head and second circle to burn the head while up.On the camshaft limit rotary device can be set, can not continue clockwise shearing after making cam arrive maximum helical pitch, can only twist to extreme lower position by the another mistake hour hands.

More than several structures all be to make second and third circle burn head to move up and down.

The described burner of Figure 25 by burn 55, gaseous mixture air inlet pipe 36, flexible pipe 54 and induction tunnel 53 form, when adopting the described structure of Figure 21 to Figure 24 and Figure 27 to Figure 31 to regulate to burn upper-lower position, can adopt this burner, the flexible pipe available metal, also available nonmetallic.

Figure 26 is the another kind of mode that induction tunnel connects with the gaseous mixture air inlet pipe of burning head, and promptly light pipe connects, and the gaseous mixture air inlet pipe 57 of burning head can slide up and down at the inwall of induction tunnel 56, and because the gap is little, gaseous mixture can not spill, and faying face is answered fine finishining.The described burning of Figure 21 to Figure 24 and Figure 27 to a Figure 31 up-down adjustment structure can adopt the burning head and the induction tunnel of this connecting mode.

The described structure of Figure 27 is regulated first and second circle and is burnt a upper-lower position, adopts hydraulic regulation, and its principle is identical with Figure 21.

The described structure of Figure 28 to Figure 29 is regulated first and second circle and is burnt a upper-lower position, step carriage 52 is held the 3rd circle and is burnt head, locating hole is set on this carriage is used to insert the backstay that first and second circle burns head, two groups of cams are held first and second circle and are burnt head, the cam top was identical with the distance at axle center when two groups of cams reached maximum helical pitch, but the basic circle difference of two groups of cams, the cam base circle corresponding with first lap burning head is less.When cam forwarded extreme lower position (being that the basic circle place contacts with the burning head) to, it is minimum that first lap burns a position, and second circle burns a position between first lap and the 3rd encloses.

The structure that first and second circle of the described adjusting of Figure 30 to Figure 31 burns a upper-lower position adopts hydraulic means to join step carriage 52 and waveform carriage 6, when three circle burning heads are in the same horizontal plane, step carriage 52 is held the 3rd circle and is burnt head, waveform carriage 6 is held first, second and third circle simultaneously and is burnt head, and waveform carriage 6 is lived by two velamen hydrodynamic pressure mastheads.The waveform carriage also descends when passive hydraulic stem, and first and second circle burns head and descends simultaneously, no longer descends when head is fallen on the step carriage when second circle burns, and the first lap head continues to descend till falling on the step carriage.Three circle burning heads can be transferred in the same horizontal plane again when passive hydraulic stem rises again.

Figure 32 burns head to be placed on the structure chart that burns on the head bracket, burning head among the figure is the simple technique of painting, figure (seeing Fig. 4, Fig. 5 etc. for details) after cutting open does not in detail draw, when each burning head is in same horizontal plane, each burns the head bottom and is then held by waveform burning head bracket, when first, second and third circle burnt the head rising, then burning the head bottom had a segment distance with the burning head bracket, and each backstay can slide in the hole of carriage.With the purpose of bracket design waviness is to be convenient to auxiliary air enter in the flame from bottom to top.

Figure 33, Figure 34 are described to be worm screw location structure figure, and worm screw is installed in two axle sleeves, can only rotate, and can not move along axis direction.Two axle sleeves are installed on the fixed head, and two installing holes 2 are arranged on the fixed head, and available bolt is through in two installing holes, and fixed head is locked on the carriage 22.

Figure 35 to Figure 40 is first kind flame and/or first kind of structure chart of thermic load control device, and this structure chart is an example to control four burning heads.The connected mode of shell and flame control device carriage slightly can be welded a metallic plate (this metallic plate also can be cast as one with shell) among the figure on shell, holes on the metallic plate, with screw rod this plate and carriage is linked together again.The shell of this device has four combustion gas ventholes, and an igniting combustion gas venthole is arranged, and a combustion gas air admission hole is arranged on the end cap.Five corresponding cross section regulating tanks of giving vent to anger are arranged on the rotating shaft curved surface, and each regulating tank communicates with the rotating shaft center hole by intercommunicating pore; Rotating shaft one end has an air inlet cross section regulating tank, and this groove communicates with centre bore.When the intercommunicating pore of the cross section regulating tank of giving vent to anger faced corresponding with it venthole, the intercommunicating pore of other each regulating tanks was also facing to corresponding with it venthole.At this moment the area maximum that overlaps with air admission hole of air inlet cross section regulating tank, the cross section maximum of promptly ventilating.Before the igniting, rotating shaft is not to be arranged in the figure position, and air admission hole and each venthole are all closed at that time, i.e. the place that do not overlap of each regulating tank and each hole.Just be arranged in the figure position after rotating 90 °, at this moment air admission hole that each regulating tank is corresponding with each or venthole overlap the area maximum.When rotating rotating shaft, the fork of driving part is stirred the bump rod of electronic striking, the compression spring, fork breaks away from the bump rod when rotation reaches 90 °, and bump rod bump piezoelectric element produces electric energy, makes the igniting pin produce spark, each venthole conducting simultaneously, lighted a fire pin mark combustion of igniting combustion gas, flame is sprayed onto and burns on the head, each is burnt head light.If use pulse ignition device, connect power supply and promptly produce spark, then do not need the combustion gas of lighting a fire, can cancel the igniting combustion gas cross section regulating tank of giving vent to anger on the rotating shaft, can cancel igniting combustion gas venthole on the shell.It is other also can be installed in big burning head to the igniting pin when adopting impacting type electronic striking device, the combustion gas part of so also can not lighting a fire.After the air admission hole conducting, combustion gas enters air inlet cross section regulating tank from air admission hole, enters centre bore again, enters each intercommunicating pore again, enters each regulating tank again, enters each venthole again.When being among the figure position, the flame maximum, the igniting combustion gas is in burning, and after continuing to rotate to an angle, the igniting combustion gas is closed, and at this moment the steel ball of feel device drops in the corresponding locating slot 83.Be rotated further, air inlet cross section regulating tank sharply reduces the air inlet cross section, and each flame that burns on the head begins to reduce when reducing to a certain degree, up to less than half, first lap burns the fray-out of flame on the head when being rotated further again, and at this moment the steel ball of feel device then drops in the corresponding locating slot 84.When steel ball dropped in the locating slot 85, second circle burnt head and extinguishes; When steel ball dropped in the locating slot 86, the 3rd circle burnt head and extinguishes; When steel ball dropped in the locating slot 87, the 4th circle burnt and has only a minimum circle fire on the head.Flame all extinguishes to continue to rotate then again, each air inlet/outlet Close All at this moment, and steel ball drops in the locating slot 88.In the rotating shaft rotation process, the air inlet cross section begins sharply to reduce earlier, slowly reduces again, closes at last.The characteristics that this control device is regulated flame are: all reduce flame → continue earlier simultaneously and reduce the flame that first lap burns on the head and reduce the flame that second circle burns on the head and reduce the flame that the 3rd circle burns on the head and reduce the 4th circle and burn flame on the head to low baking temperature state → Close All until closing → continuing until closing → continuing until closing → continuing.The part that the abcdefga curve surrounds among Figure 39 is an air inlet cross section regulating tank, the 73rd, air admission hole is when rotating shaft rotates and the relative position of air inlet cross section regulating tank, change the variation in air inlet cross section as can be seen from relative position, this variation requires consistent with the variation and the flame in the cross section of giving vent to anger of Figure 40.Radius is that the off-centre operation of R can change Archimedes spiral among Figure 39.Another group chain-dotted line place can be provided with another group give vent to anger cross section regulating tank and two groups of air inlet cross section regulating tanks among Figure 40, but that the axle in the shell needs is shorter than shell.

Figure 41 be the rotating shaft air inlet cross section regulating tank of first kind flame and/or second kind of structure of thermic load control device to diagrammatic sketch, other parts of this control device with similar first kind identical.The characteristics that its regulates flame are: air inlet cross section regulating tank does not work to regulate flame substantially, only plays to greatest extent the conducting air admission hole and closes combustion gas, and the cross section regulating tank of respectively giving vent to anger is regulated the flame on each self-corresponding burns separately.The flame adjustment process is: turn down first lap burn on the head flame until close → turn down again second circle burn on the head flame until close → turn down the 3rd circle burn on the head flame until close → turn down the 4th circle burn flame on the head until the low baking temperature state until closing.When closing first lap flame, the second circle flame can be constant, also can reduce a part, decides according to the regulating tank relative length, designs relative length as required.Wherein the part that surrounded of abcdefga curve is an air inlet cross section regulating tank, the 73rd, and air admission hole is when rotating shaft rotates and the regulating tank relative position of air inlet cross section.

Figure 42 to Figure 43 is that the rotating shaft end face air inlet cross section regulating tank of the second class flame and/or the third structure of thermic load control device is to diagrammatic sketch and the rotating shaft curved surface cross section regulating tank expanded view of giving vent to anger, this structure is combined by two kinds of control methods, top is first kind of the first kind, there are four regulating tanks of giving vent to anger the lower part, and two kinds of methods can natural transition.After using first kind of regulating tank, turn round the low baking temperature state, continue the twisting rotating shaft again, then the flame on the 4th circle burning head can reach maximum, continue the twisting rotating shaft again, the 3rd circle burns head and goes up initial burning and reach maximum gradually, like this, twist rotating shaft always, up to first lap burn head fight and reach maximum.Continue the twisting rotating shaft again, each fire that burns on the head diminishes again simultaneously, up to all extinguishing.Do not burn fray-out of flame on the head if do not allow, oppositely twist rotating shaft, then the principle of second kind of flame of the function of lower part regulating tank and the first kind and/or thermic load control device is identical.Rotating shaft both can be rotated in the forward 360 °, but 360 ° of reverse rotations again but can only be rotated in the forward when needing electronic striking to light, if with pulse firing then no matter positive and negative rotation all can.The part that the abcdefghijka curve is surrounded among Figure 42 is an air inlet cross section regulating tank, and wherein the ij section is an eccentric arc, can change Archimedes spiral into.

The shell of feel device and counter-sunk screw, spring do not draw (seeing Figure 36 for details) among Figure 44, and when steel ball was stuck in a certain locating slot, corresponding flame (burning flame on the head or the igniting combustion gas) just extinguished, or is in the low baking temperature state.Firmly big slightly when at this moment twisting rotating shaft, could allow steel ball skid off locating slot, so hand is just felt.

Figure 45 is a low baking temperature fuel gas hole schematic diagram (amplification), and the combustion gas in the rotating shaft center hole is introduced into low baking temperature fuel gas hole 92, enters expanded bore 91 again, enters venthole again.The purpose of design expanded bore is to prevent that lubricating oil on the rotating shaft from entering the low baking temperature fuel gas hole and stopping up this hole.

Figure 46 is the another kind of arrangement figure of locating slot on the rotating shaft and since when being arranged on the line between each groove distance too little, be not easy to processing and regulate flame, therefore divide two to arrange and put.Corresponding therewith, the feel device also should have two, and rotating shaft suitably extends.

Figure 47 to Figure 48 is that the air inlet cross section regulating tank of end face of rotating shaft of first kind flame and/or the 4th kind of structure of thermic load control device is to the cross section regulating tank expanded view of giving vent to anger of diagrammatic sketch and rotating shaft curved surface.This rotating shaft is combined by two cover flames and/or heat load adjustment groove, and first kind of the top and the first kind are identical, and second kind of the lower part and the first kind are identical.Can spontaneous combustion carry out the transition to second kind of flame by first kind of flame.Promptly first kind of flame arrives the low baking temperature state, continue the twisting rotating shaft again, the then whole conductings of the regulating tank of giving vent to anger of second kind of flame, it is maximum that flame reaches, by being conducting to maximum a process is arranged, but tolerance very much not can not burnt during conducting just, acquires a certain degree and could burn, but very little from being conducting to the torsion angle that reaches maximum flame situation.Continue the twisting rotating shaft again, its Principles of Regulation are identical with second kind.Two kinds of flame control methods of design adapt to the cooking needs more on a control device.This rotating shaft can also reverse, during the second portion counter-rotating, can forward maximum flame to by minimum flame, each flame that burns on the head reduces simultaneously when continuing counter-rotating again, continue counter-rotating again, three maximum circle flames extinguish simultaneously, but enter the low baking temperature state of first's flame, continue counter-rotating, each burns head and upward progressively begins to light flame by ringlet to great circle, and add big flame simultaneously until maximum flame status, and continuing counter-rotating again, flame all reduces until closing simultaneously simultaneously.Three kinds of structures of first kind flame and/or thermic load control device first, second and third this rotating shaft that all can reverse is regulated flame, does not repeat them here.The part that abcdefghlija surrounded among Figure 47 is an air inlet cross section regulating tank, and the ij section is an eccentric arc, can change Archimedes spiral into.

Figure 49 to Figure 52 is first kind flame and/or the thermic load control device second group structure chart, wherein Figure 49 is an outline drawing, the air admission hole of this structure is opened on the shell curved surface, and air inlet cross section regulating tank is also opened on the rotating shaft curved surface, and other parts are identical with the various structures of the first kind.Figure 50 to 52 has enumerated three kinds of air inlet cross sections of rotating shaft regulating tank expanded view of this structure, wherein Figure 50 and Figure 51 can with the supporting use of cross section regulating tank of giving vent to anger of Figure 40, Figure 52 can be used with Figure 43.

Figure 53 to 57 is the second class flame and/or first kind of structure chart of thermic load control device, form by anterior device and these two parts of posterior means, anterior device mainly adopts existing electronic ignitor switch or pulse ignition switch, but a combustion gas venthole only is set, igniting combustion gas venthole then is set when adopting the electronic striking device, the combustion gas person in charge communicates with the air inlet pipe of anterior device, the venthole of anterior device communicates with the air admission hole of posterior means, the twisting rotating shaft can be enabled the sparking function, and can regulate whole intake velocity, each burns the thermic load of head thereby regulate burner simultaneously; Posterior means is made up of shell, end cap, adjustable combustion gas nozzle, pilot plunger, connecting plate, location-plate, adjusting screw(rod), handle and total air admission hole, pilot plunger and connecting plate pass through thread connection, pilot plunger can be inserted in the air admission hole of adjustable combustion gas nozzle, adjusting screw(rod) and handle pass through thread connection, total air admission hole communicates with the venthole of anterior device, the length of pilot plunger has nothing in common with each other, and the plunger that burns the more little correspondence of head is long more; The twisting handle can promote adjusting screw(rod) and move with the mobile adjustable plate of integral body, therefore can mobile simultaneously pilot plunger, successively to change each nozzle air inlet cross section, thereby successively change each combustion gas nozzle jet velocity and burn a thermic load to change each, can enclose → close the 4th and enclose → turn down the 3rd and enclose → close the 3rd circle according to turning the 4th down ... rule regulate flame, when regulating and closing the 4th circle, the 3rd circle can slightly be turned down, can not turn down yet, determine according to two plungers lengths relation; Can also twist certain plunger separately to regulate the corresponding flame that burns on the head; Three kinds of regulation schemes can use separately separately, also can use simultaneously; The cancellation anterior device increases ignition device on posterior means, also can control flame and/or thermic load.Location-plate by up and down two form, its effect is that handle is rotated in its hole, does not move axially and do not produce.Location-plate and gas-cooker main framing connected mode are slightly.Utilize existing electronic ignitor switch (making improvements slightly) among Figure 53, the part that wherein drives rotating shaft is not drawn.

Figure 58 is the 3rd class flame and/or second kind of structure chart of thermic load control device, and this structure is also identical with similar first kind of structure first, just second portion structure difference.Its operation principle with similar first kind identical, just the shape of combustion gas nozzle and shell has been done a little variations, does not repeat them here.In addition, more than in two kinds of structures cooperating between plunger and combustion gas nozzle both can be unthreaded hole and polished rod, can be again screw thread.When adjustment structure difference when the screw thread, do not repeat them here, because of total principle is by the advancing and move back the air inlet cross section of regulating air nozzle of plunger, and the specific embodiment is a lot.

Figure 59 to Figure 64 is the first kind and the second class flame and/or thermic load control device drive part structure chart, and the relevant portion of this part and existing electronic ignitor switch is basic identical.Its operation principle is: handle is moved up, and the compression spring promotes safety collar simultaneously and leaves trough, and handle is promptly rotatable, and drives the driven shaft rotation, thereby by the rotation of bevel gear driven rotary axle.Driven shaft drives the shift fork rotation simultaneously, shift fork is stirred bump rod (not drawing among the figure) the compression spring (not drawing among the figure) of electronic striking device, when driven shaft rotates about 90 °, shift fork breaks away from the bump rod, the bump rod is bump pressure sensitivity battery under the elastic force effect, thereby the spark pin produces spark, all conductings of combustion gas and combustion gas of at this moment lighting a fire, and kitchen range take fire.This device with have the electronic ignitor switch difference now and be: this device is can positive and negative rotation arbitrarily angled, and the positive and negative rotation of existing apparatus has only in 180 °; This device is connected by bevel gear with flame and/or thermic load control device, and the driven shaft and the rotating shaft of existing electronic ignitor switch are same axises.Can also do other design to this device, be about to driven shaft and rotating shaft and unite two into one, then driving shaft and rotating shaft axis then can omit driven shaft and bevel gear point-blank, but the rotation direction of twisting handle is different with existing technology.Need to prove, the understanding of existing electronic ignitor switch is derived from dismounting analysis to material object, do not find pertinent literature, rise so the title of its each parts is inventors.This drive unit only is fit to the first kind and the second class flame and/or thermic load control device.There are driving and ignition device in the first of the 3rd class flame and/or thermic load control device.
