Description

Gas-cooker

Technical field

The present invention relates to a kind of gas-cooker that is used for the cooking field, specifically, relate to the support (hereinafter to be referred as support) of burner, flame and/or the thermic load control device of gas-cooker and supporting pot, kettle etc.

Background technology

The burner of existing gas-cooker generally has two to burn head (being linked to be an integral body), three circle fire holes, the flame of a wherein minimum circle fire hole is controlled by a combustion gas nozzle, another flame to two circle fire holes is controlled by another combustion gas nozzle, control the size (burner that has has three circle fire holes, but has only a combustion gas nozzle) of whole burner flame by the tolerance of two nozzle ejections of a switch control.In addition, the height of gas-cooker support is changeless.This gas-cooker has following significant disadvantages: 1, pyrosphere less (the general 10cm of a big burning diameter of burner), and pyrosphere quantity is few, and corresponding optimal heat load is also little.Under and the situation that quantity is few little at pyrosphere if design thermic load very greatly, then the spray orifice of combustion gas nozzle must be very big, and jet velocity is very big, and big load takes off fire easily when burning, and the too concentrated auxiliary air that causes of flame is difficult to enter flame inside, is easy to generate black smoke and carbon monoxide.2, the adjustable range of thermic load and/or flame size is little, can not satisfy the culinary art needs.Be transferred to minimum thermal when load from maximum heating load, the variation of thermic load is not continuous, little load a lot " gear " transfer less than.Because bigger flame of corresponding two circles of combustion gas nozzle, and the thermic load of the flame that this two circle is bigger accounts for about 85% of whole burner thermic load, when turning this two circles flame down, little of to a certain degree then the speed of a fire hole is too little that the phenomenon that tempering is extinguished takes place owing to combustion gas and Air mixing gas blowout go out to burn, flame is little also need to continue to turn down flame during to the tempering limit, then can only allow this two circles fray-out of flame, therefore less than the tempering limit of two bigger circle flames greater than the thermic load of another ringlet flame just transfer less than.And when the bigger flame of two circles was transferred near the tempering limit, because combustion gas nozzle jet velocity is very low, the little air that entrainments was easy to generate black smoke and carbon monoxide.3, burner heat absorption and the heat transfer rate made such as cast iron is fast, heat by burner and induction tunnel thereof to around transmit, the kitchen range thermal efficiency is reduced.4, every circle fire hole all is on the same horizontal plane, when with the culinary art of pan, kettle, when heating up water, (draw a vertical ray from the fire hole top center intersects with pot or kettle bottom the vertical distance of fire hole bottom pot, kettle, intersection point and the distance of fire hole top center abbreviate fire hole and vertical distance at the bottom of pot or the kettle as) all equate, can reach preferably burn, heat-transfer effect; When with the curved surface pot of sphere or other shapes, each fire hole is inequality with the vertical distance of pot, the fire hole of the interior circle flame is minimum with the vertical distance of pot, the fire hole of outermost one circle flame is maximum with the vertical distance of pot, then flame combustion situation and heat-transfer effect are just not good, and being heated everywhere of pot is different, thereby temperature is different, the influence culinary art.5, the height of the support of existing gas-cooker is changeless, also is unfavorable for culinary art.The height of support is fit to when flame is big; But when flame hour, flame is too big with the distance of pot, kettle, heat-transfer effect is poor, heat loss is big; Need support shorter during with pan, when with the curved surface pot, but require support higher.Obviously, the height of the support incompatibility cooking requirements of one's work that immobilize.

Positive meaning: 1, the adjusting of flame and/or thermic load can be satisfied the cooking requirements of one's work.Load can be realized continuous adjusting substantially from the maximum heating load to the minimum thermal; Flame profile also can be selected, and the flame of three kinds of shapes can be arranged under the promptly equal thermic load situation.Burn flame on the head as both can turn each earlier down comprehensively, again from maximum burn head turn down one → close this ... the minimum flame on surplus minimum burn only; Again can from maximum burn head turn down one → close this ... the minimum flame on surplus minimum burn only; Can also turn down simultaneously and respectively enclose flame until closing simultaneously.Three kinds of methods can be transferred to the minimum thermal load from maximum heating load, go up the flame profile difference but burn head in the adjustment process, to adapt to different cooking needs.2, the thermal efficiency increases.The fire hole circle is made with fire-resistant heat insulating material, and its heat transfer derivative is significantly less than metal material, therefore conducts heat and the radiation loss minimizing; Part is burnt head and support can up-down adjustment, can adapt to the variation of the shape of the variation of flame and/or thermic load and pot or kettle, is convenient to better to pot or kettle heat transfer.The maximum head that burns of at least two circles can make each burn head and be arranged to matrix, so that each fire hole equates with the vertical distance in the bottom of a pan to rise when with the curved surface pot; When with pan, again each is burnt head and transfer in a horizontal plane (is benchmark to burn crown face).When support being heightened when very big with curved surface pot or flame; When support being turned down when very little with pan or flame.3, combustion position improves, and helps improving the thermal efficiency.Gas-cooker is in the market chewed by a main jet and is controlled about 85% thermic load, and then injection diameter is big to reach very big thermic load, must reduce jet velocity when turning flame down, because injection diameter is constant.If the thermic load of this nozzle is transferred to 30% by 100%, then gas speed is also reduced to 30% (falling low gas velocity by reducing air pressure), at this moment jet velocity is too little, entrainment the ability of air, it is insufficient to cause burning, combustion gas that sprays simultaneously and Air mixing gas speed too low (being lower than burning velocity) can produce carbon monoxide and black smoke, if then can be extinguished in tempering from fire hole.If become three but main jet chewed by one, then the nozzle diameter diminishes, and jet velocity slightly reduces, but total jet amount remains unchanged.When turning flame down, turn off the nozzle that two great circles burn head, the less nozzle that burns head of an only surplus circle, three circle thermic loads can be transferred to below 30% by 100%, yet the gas speed of the nozzle of the less burning head of that circle is constant, therefore this figure flame combustion situation is constant, carbon monoxide and black smoke can not occur, also can tempering.The gas speed of this nozzle is suitably reduced a part more also can normal combustion.In a word, under the equal thermic load condition, the combustion position of big injection diameter, stingy speed is poorer than the combustion position of little injection diameter, atmosphere speed.Therefore, design several circles burning heads and several combustion gas nozzle more and help improving medium and small flame burning situation, also help improving the thermal efficiency.

Fig. 1 is described to be gas-cooker important component part overall construction drawing, and the fire hole that every circle burns on the head among the figure has several, and about fire hole diameter 1.5-3mm, the thick more then fire hole of fire hole circle diameter is big more.Four volumes burn in the head, having first to three circle to burn head can move up and down, promptly twist worm screw 15 and can drive the regulating sleeve rotation of burning 3 a band helical gear that link to each other or worm gear with the 1st circle burning the 1 and the 2nd circle, 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 10 to Figure 11 for details.The helical gear that links to each other with the 2nd circle burning head when worm screw is rotated directly drives the 3rd helical gear and rotates.The pitch of burning the internal thread of the corresponding regulating sleeve of head with first lap〉pitch of burning the internal thread of the corresponding regulating sleeve of head with second circle〉pitch of burning the internal thread of the corresponding regulating sleeve of head with the 3rd circle, so a first lap burning rate of climb second enclose a burning rate of climb the 3rd enclose a burning rate of climb.The external diameter that a maximum circle burns head should burn the too little needs that can not satisfy cooking of head greater than 15cm.Burning head at specific combustion gas (as liquefied petroleum gas) design can design fire hole greatlyyer, allows lifting burn, and promptly flame leaves fire hole and pasting the bottom of a pan burning.Burning the head caloric receptivity like this reduces.Every circle burns the corresponding induction tunnel of head, the corresponding combustion gas nozzle of each induction tunnel, the flame control device can by reduce simultaneously respectively enclose flame or thermic load → continue again to reduce first lap flame until close first lap → continue again the to reduce second circle flame until close → continue again reduce the 3rd circle flame until close → continue again reduce the 4th circle flame until the low baking temperature state until the rule control flame status and the thermic load of closing, change the flame control device, can be according to turning down first lap flame → close first lap flame → turn down the again second circle flame → the close second circle flame ... turn down the 4th circle flame and control each until the rule of closing whole flames and burn head and go up flame profile and hot load state.More than two kinds of devices during reverse rotations, can reduce each simultaneously and burn the flame on the head and close simultaneously.Above two kinds of control methods can also be combined, in a control device, both can control flame, also can control flame by second method by first method.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, adjustable support only draws and erects the location drawing of pole, and adjustable support and operation principle thereof see Figure 44 to Figure 48 for details.Allow the layout of kitchen range chief component vertical direction put in order from top to bottom to be: the highest parts are the ordinary stents that are embedded on the adjustable support, the secondth, burn head, the 3rd is to regulate the regulating sleeve and the worm screw of burning a position, and the 4th is induction tunnel, flame and/or thermic load control device; The 5th is regulating sleeve and the worm screw of regulating adjustable support mobile jib position, and minimum is stent foot.

Fig. 2 to Fig. 9 is that burner burns head (and induction tunnel) structural representation, to be embedded in the fire hole circle that fire-resistant heat insulating material is made and burn on the framework, and with toothpaste etc. with the gap sealing of hole, has only a circle fire hole on the fire hole circle, general 5-the 10mm of fire hole circle thickness, 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 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, the general continuation gone in ring, and flows out from fire hole.The effect of aeroscopic plate is that the interior air-flow of mixing 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 one to two 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 50 to Figure 51.Induction tunnel (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.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.

In the described structure of Figure 10, 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.

Figure 11 burns head to move up and down second kind of structure chart, and different with Figure 10 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.

Figure 12 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 for details) after cutting open does not in detail draw, when each burning head is in same plane, each burns the head bottom and is then held by the 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.

Figure 13, Figure 14 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 15 to Figure 20 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 53.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 54.When steel ball dropped in the locating slot 55, second circle burnt head and extinguishes; When steel ball dropped in the locating slot 56, the 3rd circle burnt head and extinguishes; When steel ball dropped in the locating slot 57, 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 58.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 abcdefga surrounds among Figure 19 is an air inlet cross section regulating tank, the 43rd, 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 20.

Figure 21 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 abcdefga surrounded is an air inlet cross section regulating tank, the 43rd, and air admission hole is when rotating shaft rotates and the regulating tank relative position of air inlet cross section.

Figure 22 to Figure 23 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 abcdefghijka surrounded among Figure 22 is an air inlet cross section regulating tank.

The shell of feel device and counter-sunk screw, spring do not draw (seeing Figure 16 for details) among Figure 24, 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 25 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 62, enters expanded bore 61 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 26 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 27 to Figure 28 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 abcdefghija surrounded among Figure 27 is an air inlet cross section regulating tank.

Figure 29 to Figure 32 is the second class flame and/or thermic load control device structure chart, and wherein Figure 29 is an outline drawing, and 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 30 to 32 has enumerated three kinds of air inlet cross sections of rotating shaft regulating tank expanded view of this structure, wherein Figure 30 and Figure 31 can with the supporting use of cross section regulating tank of giving vent to anger of Figure 20, Figure 32 can be used with Figure 23.

Figure 33 to 36 is the 3rd class flame and/or first kind of structure chart of thermic load control device, this device divides two parts to regulate flame, and first and present switch are basic identical, just have only two gas outlets, one communicates with second portion, and another is the igniting gas outlet.Switch in the market generally has two combustion gas outlets (corresponding with two induction tunnels), an igniting gas outlet.Second portion mainly is made up of combustion gas nozzle, plunger, shell and end cap, its operation principle is: first can be by the twisting rotating shaft, regulate the air inlet cross section and the cross section of giving vent to anger, thereby regulate the combustion gas speed that enters the second portion shell, it can be transferred the jet velocity of each combustion gas nozzle simultaneously big or turn down, thereby the flame that each can be burnt on the head is transferred simultaneously greatly or turned down.Second portion changes the air inlet cross section that enters nozzle by the position of mobile pilot plunger in the combustion gas nozzle, thereby regulates the nozzle jet velocity, regulates flame size.Four plungers are linked to be integral body among the figure, and the twisting handle can make plunger move forward simultaneously or move backward.The length of pilot plunger has nothing in common with each other, burning head with maximum, corresponding indirectly (plunger is corresponding with the combustion gas nozzle, combustion gas nozzle and induction tunnel and to burn head corresponding) plunger the longest, the shortest with the plunger that minimum burning head is corresponding indirectly, by mobile pilot plunger, successively change each nozzle air inlet cross section, thereby change the nozzle jet velocity and burn a thermic load to change each, can be according to turning first lap → close first lap → turn second down to enclose → close second circle down ... rule regulate flame, regulate and when closing first lap, second circle can slightly be turned down, also can not turn down, determines according to two plungers lengths relation; Two kinds of control methods can use separately separately, can also use simultaneously.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 33, the part that wherein drives rotating shaft is not drawn.

Figure 37 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 38 to Figure 43 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.

Figure 44 to Figure 48 is the adjustable support structure chart, transfers the principle under raising identical with the principle of an adjusting burning upper-lower position among Figure 10 to Figure 11 on support.The screw thread of the main support of adjustable support is opposite with the thread rotary orientation of stent foot.Regulating sleeve endoporus top screw thread is identical with the screw thread of main support, and lower thread is identical with the stent foot screw thread.Regulating sleeve top or bottom can be unthreaded hole, and main support with matching or stent foot then are polished rod.But the polished rod lower end should have the shaft shoulder to hold regulating sleeve (referring to Figure 11), and when adjusting trepanning bottom was unthreaded hole, helical gear can change worm gear into.Rotary worm promote the regulating sleeve rotation, and main support and stent foot does not rotate, so regulating sleeve and main support and stent foot have axially and relatively move, thereby main support can move up and down.Because thread rotary orientation is opposite up and down for regulating sleeve, so governing speed is very fast, the effect of locating rack, the one, the stroke of control main support is to guarantee that main support does not break away from regulating sleeve; The 2nd, do not allow support rotate.The simple rack of Figure 48 (i.e. support in the market) is embedded in the groove of perpendicular pole.

Figure 49 to Figure 51 is a matrix burner schematic diagram, and this burner is made up of four (is example with four) independent burning heads, and every circle burns head to be had an induction tunnel and have only a circle fire hole.Burn head and be arranged in matrix, the face position, the burning crown that is the diameter maximum is the highest, taking second place in the face position, the burning crown of diameter second, takes second place again in the face position, the burning crown of diameter the 3rd, and the face position, the burning crown of diameter minimum is minimum, the end face of each burning head is parallel to each other, each burning head is placed on the stepped ramp type carriage, and each burns fire hole end face mid point and forms curved surface profile jointly, and this curved surface is generally sphere, can be other curved surfaces, and this curved surface and curved surface pot adapt.Induction tunnel 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 Fig. 7 burning.This matrix burner is adapted at top and places the curved surface pot and be used for cooking.Present gas-cooker is generally the dual-range-head gas-cooker, and therefore can be designed to the matrix burner on one side and be fit to the curved surface pot, can be designed to plane burner suitable pan, kettle on one side.The flame of two kinds of burners and/or thermic load control device all can adopt above-mentioned all control device.

Figure 52 to Figure 53 is described to be adjustable nozzle structural representation.This adjustable nozzle mainly is made up of the support of nozzle, adjustable plate, spring, mounting spring, support and adjusting bolt with threaded hole, and the adjustable plate right-hand member is a curved surface, and adjustable plate is pressed in nozzle gas and flows out on the end face of an end, and by spring compression.When the twisting bolt, adjustable plate moves to left or moves to right, thereby makes the jet cross section of nozzle reduce or increase, thus the thermic load of regulating gas-cooker.
