United States Patent (USP) numbering 6,093,018 is issued to A Foxiao Farnham " gas burner " by name on July 25th, 2000 and discloses an improved gas burner.This burner combines the importing of control auxiliary air and the method for mixing.Patent has been used one and has been covered the structure at burner top with the coaxial cap in burner top.Be used to spray the mist of coal gas and primary air and draw into flame and this top structure has numerous side direction spouts.When using the improved burner of this kind, the auxiliary air with exact amount is the bottom of directly being sneaked into flame.The high efficiency with high-temperature characteristic of flame and the process of completing combustion have so just been obtained.

In addition, well-known gas burner with two to three flame combustion circles is also arranged.And on each burning circle numerous traditional side direction gas ports are arranged all.A common less less important burning circle that is located in the burner center is used to heat.And the main burning circle at the middle part externally or that also have is used for the cooking.Relevant for application the burner of a plurality of burning circles is arranged, visible United States Patent (USP) numbering 6,132,205 was issued to " the enclosed gas burner with a plurality of burning circles " by name of Mike Hallett on October 17th, 2000.Two burning circles that are in the center of this burner are used to heat.And the 3rd be in peripheral burning circle, is used to cooking food under other burning circle collaborative.

The gas burner of current family expenses according to the mounting structure of gas burner on furnace table surface, can be divided into the assembling of the burner of fully closed and open-type.Preceding a kind of described assembling can be described with two United States Patent (USP)s.First patent number 5,923, the 756th, be issued to name such as Harmer on June 28th, 1994 and be " device of totally-enclosed burner " (following be Harmer patent) and second patent number 6,505, the 621st, be issued to " device of totally-enclosed gas burner " (the following ripple door patent that does good) by name of being apt to the ripple door, (seeing Fig. 1 and Fig. 2 and explanation among the application) on January 14th, 2003.

From the device relevant for gas burner for cooking of above narration, can find in existing technology, also to have lacked a kind of device that can control the directed transmission of flame heat regulating.This device is a detachable, can be placed on the table top of gas burner around the superstructure of a burner, supports a cooker simultaneously again.The heat radiation that produces from flame in when cooking and the kenel of convection current can fully be controlled like this, thereby can be used to directed and heating cooker effectively.For this purpose, Application No. 11/811,521 (521 patent application) discloses the device that can control the flame heat regulating transmission of a kind of detachable of this invention.This patent application has also proved after having used this device with experimental result, can increase the efficiency of heating surface of flame when the cooking significantly.

Yet, must be clear and definite be that for reaching the purpose that increases the efficiency of heating surface, using this device is a passive scheme.This is meant that this device is just that to energy-conservation contribution the heat of controlling the flame that has generated transmits.Yet cause the form of this flame of thermal loss to be determined by traditional burner already with side direction spout.

By the patent of above-mentioned Jie Nisi and Mike Hallett as can be known, the popular traditional side direction gas port of existing in the western market gas burner.(the seeing Fig. 1 of Mike Hallett patent) that this spout is normally circular, or rectangular (seeing the Fig. 2 and the 2a of Jie Nisi patent) are again that to go to point to each relevant laterally be horizontal direction for the outside that radially penetrated the burning circle.Like this, use conventional burners just caused the mixed combustible gas body after going out many spouts of burner to each horizontal direction flow (but this mixed combustible gas body is by the generation through mixing after in burner of primary air and coal gas with supply pressure).Thereby the corresponding many flame kernels that form at the many spouts of burner place also burn towards the corresponding horizontal direction.When certain this phenomenon is the most tangible, be when the mist at spout place has by the selected Peak Flow Rate of the user of gas burner (or pressure).

Again as seen by the Fig. 2 in the Jie Nisi patent and 2a, when the top of flame and burner nozzle have one apart from the time, the top of flame is to point to corresponding oblique upper.This is because after burning mixture flows out spout, the cause that the pressure that is acted on gas promptly disappears, thereby weakened the transverse movement of gas sharp.

A cooker be positioned in flame above the time, compare with the sort of shape that makes progress naturally of flame, the cooker that the shape of the flame of being controlled by traditional side direction burner nozzle is existed has been changed.This phenomenon is discussed in 521 patent applications of the U.S. to some extent, and the flame burning that promptly is under the cooker bottom prolongs towards the corresponding horizontal direction.This is that bottom because of cooker has stopped the upwards passage of burning of flame top.Thereby force the flame that is under the cooker for effusion to the extension more of horizontal direction.

As seen, when flammable mist had the Peak Flow Rate of being supplied with (or pressure), the extending transversely of this flame had also reached maximum degree simultaneously.When this state,, also have two kinds of main shortcomings even used of the present invention control after the device that flame heat regulating transmits.They can have influence on the efficiency of heating surface to cooker negatively, particularly the efficiency of heating surface of the cooker of diameter between 15 centimetres to 20 centimetres that those are used the most extensive in daily life and most probable.

Described first kind of shortcoming is, flame top partly be that the heat of representative can just outwards escape from the gap of being made up of the top of cooker bottom and this device before they are delivered to the bottom of cooker with radiant heat and advection heat, this has just caused the loss of heat energy.Such heat-energy losses must take place.Can not look after all situations that when the cooking, comprise the Peak Flow Rate of burning mixture actually because have the device of fixed dimension.In fact this device size comprises the diameter of inner disc top circumference, is to design according to qualifications after the most probable situation of having considered when using this device in the cooking.This situation has comprised the applicability of this device, wherein comprises again being used the adaptability of cooker size and the factor of energy savings degree by the most extensive and most probable ground.

Described second kind of shortcoming be, the major part on flame top is forced outwardly extends the bottom surface of removing to contact cooker, partly is all towards outer garden week of cooker bottom surface and those are touched.This has just caused outward extending at the center of cooker bottom surface " cold temperature area ", thereby just has influence on the efficiency of heating surface.In addition, if the bottom surface of cooker is placed on when being higher than the position that the flame top can reach, the prolongation phenomenon of flame more can be aggravated the cooling phenomenon of flame.This is because the flame top with maximum temperature can not directly touch the cause of kind at the bottom of the cooker.The cooling phenomenon of this kind flame must be negative for the high efficiency of heating surface that will obtain when cooking like this.

It must be understood that according to the above-mentioned explanation of first kind of shortcoming to loss heat energy, except the factor of the horizontal sensing of burner nozzle, the oversized dimensions factor of other flame (outward) circle also can cause the heat-energy losses when cooking.Even when the burning circle of those oversized dimensions had the spout that makes progress, this heat-energy losses also will inevitably take place.In above conclusion, the oversized dimensions of flame circle is meant that the size that is used cooker with the size of apparatus of the present invention and those inconsistent the most extensive and most probable.The most of burners that for example are included in the gas burner on the Chinese market in the Asia have the structure of two flame circles.Wherein have a undersized burning circle and that is in central authorities to be in peripheral large-sized burning circle, this large-sized burning circle has the circular or square spout of side direction.Yet the size of the sort of outer flame circle is all very big usually, and wherein Zui Da diameter can reach 12.5 centimetres.The burning circle that uses the sort of structure must cause the loss of heat energy when the cooking.

Be the efficiency of heating surface of further improving when the cooking like this, the present invention must be conceived to have (outside) flame circle of the burner of novel jet nozzle passage and optimum size.It can be used to can control the device that flame heat regulating transmits in conjunction with what invented, thereby optimization ground adapts to the cooker that those are used size with having the most extensive and most probable.

The novel jet nozzle passage of the burner in the imagination has the angle structure with respect to horizontal direction, and it can be used to guide flowing and completing combustion of burning mixture.Can there be certain structure to guarantee to produce the flame kernel that optimum stabilization is arranged again in the novel jet nozzle channel outlet.Thereby can prevent that flame kernel breaks away from the phenomenon that burning is enclosed and flame kernel jumps repeatedly around the spout outlet when burning.

Obviously, compare with the passive technical scheme that device provided that can control the flame heat regulating transmission of disclosed the sort of detachable in the U.S.'s 521 patent applications, burner nozzle is comprised that it points at the change of inner structure and the optimum size of definite burning circle, is a kind of technical scheme of active for improving flame heat efficient.The present invention just can propose a complete technical scheme that improves flame heat efficient when the cooking after in conjunction with these two kinds of schemes like this.

The material that the present invention also can be conceived to select to have corresponding big thermal capacity is made the device that this control flame heat regulating transmits.Like this, also be a kind of additional efficiency factor for the thermal efficiency that improves when cooking.

House gas boiler is the utensil that people widely use.Use gas furnace to expend the fuel gas of enormous quantity, also made a large amount of carbon dioxides simultaneously.The carbon dioxide of this manufacturing is to be incorporated among all carbon dioxides with greenhouse effects of human society manufacturing.

Like this, there is tangible demand in current society: the burner that the novel jet nozzle passage is arranged that provides a kind of of the present invention and controlled heating capacity transfer device to combine to gas burner, thus greatly improve the efficient of flame heat.The present invention simultaneously also can bring additional benefit, comprises the fuel gas that saving consumes, and it helps reducing cost; With the carbon dioxide that greenhouse effects are arranged that minimizing is produced when cooking, it helps protecting environment.

Summary of the invention

The purpose of this invention is to provide the burner that the novel jet nozzle passage is arranged that a kind of and controlled heating capacity transfer device combines.This device be detachable, an inner disc and periphery arranged.Numerous novel jet nozzle passages divide Fabric on the superstructure of a burner.The present invention is intended to be used to improve the efficiency of heating surface and the heating that prevents the cooker handle of flame when the cooking.

Inner disc of the present invention is the thin-walled ringwall that stretches obliquely upward of a hollow.Top margin with top end opening of the base of bottom end opening of a reduced size and a large-size.This inner disc is run through by numerous holes that is used as gas communication, yet with respect to dividing for the Fabric than the more sparse hole of upper part at inner disc, has denser hole to divide Fabric in the position down at inner disc.Under a preferred construction, this inner disc has inner sunken face to comprise paraboloidal garden annular shape.

Periphery of the present invention has the upwardly extending structure of a plurality of minutes Fabric on its top margin, and is run through by the hole that is used as gas communication of numerous even minute Fabric.In addition, place outside and also have a plurality of supporting constructions, they are that the additional cooker that is used to fix several detachables supports.Like this when cooking if needed, this cooker supports and can be used to support undersized cooker.

This inner disc and periphery have shape garden shape or symmetry, can be made by durable metal or metal alloy.Yet when the thermal capacity of considering the making material especially and thermal conductivity, also can make of ceramic material.This is because high thermal capacity that ceramic material had and low thermal conductivity help improving the efficient of heating.

This inner disc and periphery are placed on the furnace table surface simultaneously.Inner disc has centered on the superstructure of a flame burner.The periphery is again around this inner disc, supports again simultaneously to be placed in it and to extend upward a cooker on the top.This extends upward and can be used as the handle that flame baffle is protected cooker in addition, makes it can not be subjected to unnecessary heating when the cooking.

Use the present invention and can improve when the cooking flame the efficiency of heating surface of cooker.Inner disc has been to control the convection of heat of flame generation and the kenel of radiation to the contribution that improves the efficiency of heating surface.In control during thermal-radiating kenel, the downward and outside heat radiation that inner disc deviates from the cooker bottom to flame focus reflection is again removed heating cooker to the bottom of cooker.In the control thermal convection current, when comprising the kenel of convection current of air, this inner disc has guided auxiliary air with lower temperature ambient flow around the flame to go to participate in flame burning to flame.This auxiliary air is mainly by flowing into by the approach than small flow resistance that hole provided at intensive minute Fabric of inner disc lower position.Inner disc has surrounded air with higher temperature and burnt gas that the burning back produces again, it is upwards flowed controlledly remove heating cooker.

Peripheral contribution for the raising efficiency of heating surface is that its barrier wall as a heat has stopped by inner disc to extraradial heat.It has in addition extend upward provide the cooker bottom and should the periphery between a gap, thereby make the air of higher temperature and the waste gas that the burning back produces outwards upwards to flow out by this gap, and the outer wall of cooker is heated continuously.

The superstructure of burner has garden, a detachable top lid and a hollow stem that makes progress that is fixed on the furnace table surface by the present invention's design.The neck of hollow is a round ring wall that makes progress, and has the horizontal garden ring and the vertical centre gangway at a top.Its centre gangway is used for mixing the burning mixture that the back forms by primary air and fuel gas.The garden is stamped a horizontal top and has been connected a downward round ring wall, thereby has drawn into the inner interior concave space under shed of garden lid.The round ring wall has an outer surface (or outside anchor ring), an inner surface (or interior side ring surface) and to be in the horizontal garden ring as the bottom surface of bottom.And the garden ring on the garden of top cover bottom ring and neck top matches.

In addition, numerous identical vertical slots under shed are arranged on the round ring wall of top cover.They are radially along the garden ring that divides Fabric, lid bottom, cut-out garden garden week.Each groove contains: have one the space of big outwardly open one bigger continuous expansion connected have one less to one of inner opening less space.This bigger space includes one again outwards also obliquely upward to the inner surface that points to.This outside opening than large space is to be on the outer surface of top cover ringwall.And this less space is to be on the inner surface of ringwall to inner opening, thereby has connected the interior concave space of top cover.

When garden shape top cover was positioned on the neck and matches with it, this just will the numerous downward vertical slot on top cover be transformed into the novel gas port passage of corresponding burner of the present invention.Wherein the outside bigger opening of each vertical slot becomes the gas outlet of each spout passage.The inside less opening of each vertical slot becomes the air inlet of each spout passage.Each novel spout passage contains the bigger space of expansion gradually and has connected a less space like this.This less space is used for by having the burning mixture of big flow velocity.And this bigger extending space has slowed down the flow velocity of the mist that flows into gradually, and guides its direction of pointing to obliquely upward along this space inner surface to flow.When being lighted in this novel passage gas outlet, the mist with low flow velocity just can form stable flame kernel like this.

This retention flame center along the direction of the sensing oblique upper of this extending space, developed into along this equidirectional burned flame.And from the surrounding space of flame and the auxiliary air that comes, after having passed through to control the hole of flame heat regulating transfer device, supported the completing combustion of this flame.The flame top that has maximum combustion temperature has so just directly contacted the bottom surface of a cooker, thereby has greatly increased the efficiency of heating surface of flame when the cooking.

Have annular outstanding limit in a side direction garden minor official on the shape top cover of the garden of burner superstructure of the present invention again, it has obliquely upward to the garden annular bottom surface that points to.The outstanding limit of this side direction is minor official to be to be in the outer ring surface of garden lid and to extend laterally along the garden hd top face, and should the minor official base ring face in outstanding limit is the inner surface direction of pointing to obliquely upward along many spout passages of correspondence.In addition, one is to be placed in the minor official part that is connected with garden bezel ring, shape exterior wall in this outstanding limit to the garden of under shed annular groove.This projecting edge is used for preventing to cause owing to splashing down of liquid the phenomenon of knock down the flame when the cooking.The garden annular groove that this centers on is the burning that is used for stablizing flare, and particularly stable user when gas burner selects burning mixture to light when minimum pressure (flow velocity) and the flare that produces.

In another embodiment, the sensing as the less space of the usefulness of air inlet of novel jet nozzle passage of the present invention has the angle from zero degree to nine ten degree with respect to lateral.

Two parts that openly comprised of the present invention.First partly relates to the device that can control the flame heat regulating transmission that is produced by conventional burners.This burner has the gas port of side direction.The same United States Patent (USP) 521 that discloses of first part is applied for identical.Second partly relates to the burner of (outward) pyrosphere with novel jet nozzle passage and suitable dimension, and it combines with above-mentioned device.Thereby the efficiency of heating surface of the present invention's flame when just having proposed a complete technical scheme and improving the cooking.

(I) can be used to control the device that flame heat regulating transmits.

The structure of the boiler face of the modern gas burner known to Fig. 1 and Fig. 2 have illustrated.By shown in Figure 1, boiler face has four burner and two independent fence of installing by full-closed structure.Each fence is placed on the boiler face, has covered the superstructure of a flame burner.Described Fig. 1 has duplicated United States Patent (USP) numbering 5,323,759 disclosed Fig. 1.Used parts label in former figure in the copy pattern.

Fig. 2 is the plane that the boiler face of lengthening fence is arranged.It is that duplicating of Fig. 2 by United States Patent (USP) numbering 6,505,621 forms.Used the parts label in former figure in the copy pattern.Fig. 2 has illustrated the fence 40 of having settled a lengthening on boiler face 32, and this fence extends to the back of boiler face from the front of boiler face, and has numerous single-ended horizontal stretching structures to support two cookers.

From the boiler face structure of existing gas burner illustrated in figures 1 and 2, can see that it lacks the device that can control the detachable of flame heat regulating transmission.This device can be placed on the efficiency of heating surface that also increases flame on the boiler face around the superstructure of a burner, supports cooker and the unnecessary heating that prevents the cooker handle.

The transmission of well-known flame heat regulating is to carry out by two approach of radiation and convection current.So under the effect of the burner that the novel jet nozzle passage is arranged that a kind of and controlled heating capacity transfer device of the present invention combines, the control that the radiation of heat and the kenel of convection current can improve, thereby can effectively heat cooker.The present invention just can reach and promote the purpose of flame to the efficiency of heating surface of cooker like this.

Fig. 3,4 and 5 has introduced the detachable device 100 that transmits according to the of the present invention first concrete flame heat regulating of implementing controlled.This device is made up of the annular surface hollow inner disc 102 and peripheral 130 of the quadrangle that are placed on the boiler face 166.Inner disc 102 is positioned to the superstructure 178 around a gas burner, and itself is centered on by this periphery 130.Simultaneously peripheral 130 support a cooker 168 with bottom surface 174 again, this cooker 168 is to be placed on the burner.

As shown in Figure 4, annular inner disc 102 is thin-walled ringwalls that stretch obliquely upward of a hollow, an outer surface 106 is arranged, inner surface 108, the circumference 110 of top end opening and the circumference 112 of bottom end opening.Hollow inner disc 102 from the circumference 112 of bottom end opening upwards and extend outwardly into garden week 110 of top end opening, so the size of top circumference 110 greater than the size of bottom circumference 112, they have same centre rotational axis 114 simultaneously.When the direction inner disc 102 that is prolonging from rotating shaft 114 to inner surface 108, this hollow inner disc has the inner surface 108 of a recessed bent annular.Certainly optimal scheme is that the card of this indent is a parabola corresponding to centre rotational axis 114.

Should be clear and definite be that paraboloidal inner disc is especially designed according to the kenel of purpose control radiation of heat of the present invention and convection current in this annular inner concave or the annular.

The annular inner disc 102 of this indent or interior parabolical can deviate from heat radiation cooker bottom surface 174, the outside and downward bottom of this cooker of reflected back again comprising by what flame produced.In above-mentioned outside and downward thermal-radiating direction is for the cooker bottom surface on being placed in flame.As everyone knows, radiation of heat is a three dimensions around the center directive from a thermal source.It is downward and outside in the heat radiation that is produced by flame part being arranged like this, and this just means that the heat radiation of this part directly is not used for heating cooker.After the inner disc 102 that annular hollow indent of the present invention is housed, can be reflected back heating cooker downwards and to the heat of extraradial flame, this is the present invention, than there not being inner disc of the present invention to cause the low efficiency of heating surface, can obtain one of reason of the high efficiency of heating surface.

Again as shown in Figure 4, this hollow ring inner disc 102 has numerous holes 116 by disk body again.These numerous holes 116 have been divided into two groups.Hole in first group is to divide Fabric equably on the circumference 118 of the higher position on the inner disc, and the top circumference 110 of disk body is approached in the position of this circumference 118.Hole in second group is to divide Fabric equably on the circumference 120 of the lower position on the inner disc, and the bottom circumference 112 of disk body is approached in the position of this circumference 120.But as described in Figure, hole 116 is different in two circumference 118 of the inner disc branch Fabric density on 120.

This uneven hole divides Fabric to be described by different distance " A " and " B " between two adjacent holes in Fig. 4.Distance A is the distance between two adjacent holes on the lower position circumference 120.Apart from B is distance between adjacent two holes on the higher position circumference 118.Distance A obviously is less than distance B.So another architectural feature of inner disc of the present invention is, than hole denser branch Fabric is arranged at higher position at the hole of this inner disc lower position.

Should be clear and definite, it is the present invention's special setting for the convection current of controlling flame heat regulating that this inhomogeneous hole divides the feature of Fabric.And the convection current of flame heat regulating is the convection current that has relied on air.As can be known, the convection current of this air occurs in the flame space on every side that comprises the shared space of flame.

When cross-ventilation, the air with lower temperature has bigger proportion, thereby has occupied the space at position down.In contrast, the air with higher temperature has less proportion, thereby has occupied the space than the upper part, has also comprised the space that flame is occupied certainly.The characteristics determined of this proportion the form of natural convection air: promptly cold air has the surrounding space of lower temperature from flame, flows to flame via the spatial channel that occupies lower position, goes to participate in flame burning.The air of heat has higher temperature, and it occupies higher position, space, from the flame diffluence that makes progress.

The inner cover hole of the denser minute Fabric in position down that is arranged on of the present invention like this is to mobile the provide less resistance of colder auxiliary air to the superstructure 178 of burner.Auxiliary air is vital for burning, because contained oxygen forms the burning of burning mixture and is absolutely necessary the flame in this auxiliary air that flows.And this mist is formed by the mixing of the fuel gas of primary air and supply in burner.

The quadrangle periphery 130 that Fig. 4 narrated is made up of four identical plates of upwards settling 132.Every plate also has outer surface 134 and inner surface 136 except height " H2 " is arranged.These four plates 132 connect successively and form peripheral 130, the tetragonal horizontal top margin 138 of its tool and a base 140 and a central symmetry axis 142.There is numerous hole 144 to divide Fabric equably on each piece plate in addition.Comprise according to one of described purpose of the present invention and can control cross-ventilated kenel, as can be known the number of the hole 144 by the quadrangle exterior wall many than by inner disc hole 116.Its essence is that the gross area of placing hole outside is greater than the gross area on inner disc.

By Fig. 4, the every plate of upwards settling has an extended structure that makes progress 146 on top margin 138 position intermediate again.This structure also has first and second sides that make progress 148 and 150 compositions of equal height " H3 " by top 152.As described in Figure, the height of dual-side " H3 " is the height " H2 " that is lower than every plate.The length of side of dual-side 148 and 150 generally is longer than on the top 152 that extends upward structure in addition, extends upward 146 functions with thermal barrier properties like this.

After cooker is placed on the burner, it is contemplated that extend upward structure 146 can stop by flame produce outwards, flow to the hot-fluid of this extended structure.If there is no this structure, this hot-fluid that outwards flows can change the hot-fluid that upwards flows into.So upwards the hot-fluid that flows can be placed on the flame one, and heats with object and parts that this hot-fluid that upwards flows orientation is intersected.As described in Fig. 4 A and 5, cooker 168 is to be placed on the extending upward on the structure 146 of quadrangle periphery, and one parts handle 170 is to be on the same vertical plane with the center of structural top 152 and peripheral symmetry axis 142.Extend upward the handle 170 that structure 146 can prevent cooker 168 like this and be subjected to unnecessary heating.

By shown in Figure 5, except this function, this structure 146 that extends upward is to be designed to support a kind of cooker that planar base surface 174 is arranged by the present invention, perhaps have convex bottom face as frying pan and so on cooker.

By Fig. 4, first group being in than the upper part with than descending the fixing with structure 162 and 164 of position arranged on the inner surface 136 of upper sheet space again at each.Should than the upper part fixing with structure 162 be dispose near and be lower than horizontal top margin 138 to upper sheet space, and should be that disposal is on close horizontal base 140 to upper sheet space with structure 164 at the fixing of position down.Should fixing be positioned in and extend upward simultaneously on the link position of 146 first side 148 with structure 162 and 164.The fixing of equally second group also disposed on the inner surface 136 of upper sheet space with structure 163 and 165.Be to dispose at approaching laterally top margin 138 than the fixing of upper part with structure 163, the fixing of position is to dispose on approaching horizontal base 140 with structure 165 under.They are positioned in and extend upward on the link position of 146 second side 150.

Above-mentioned as can be known fixing with structure, for example semicircle garden ring is that the additional cooker that is used for fixing the first and second identical detachables on peripheral 130 supports 154 and 156.Like this, undersized cooker can be placed in when the cooking on additional cooker supports.As described in Figure 4, the first additional cooker supports 154 and has the shape that resembles inverted " U ", is made up of with the identical first and second downward structure 154b and 154c a horizontal top 154a.This support 154 can be made by metal flat bar or garden rod.

When using cooker to support 154, the first downward structure 154b is inserted in first group fixing using in the structure 162 and 164 of first plate 132, and the second downward structure 154c is inserted in second group fixing using in the structure 163 and 165 of second plate 132.As described in Figure, this second plate is close to down after first plate 132 in the direction of the clock, and this clockwise direction is the symmetry axis 142 according to the periphery again.And the connection of the first and second plate formation an angle of 90 degrees.Under above-mentioned connection, two top margins 138 of the top 154a of first cooker support 154 and the first and second adjacent plates form a right angle triangle, and this top 154a is the hypotenuse of right angled triangle.

In the same manner, second cooker can be installed and support 156.By shown in Figure 3, the top 156a that so just causes the top 154a that first cooker supports and second cooker to support parallels and narrower interval is arranged.Undersized like this pan can be placed on this two parallel top structure 154a and 156a easily.

Can be sure of that owing to exist in fixing with structure 163 and 165 with structure 162 and 164 and second groups of on the respective plates first group fixing, selectable additional cooker supports the type shape that various deformation can be arranged.This distortion can be narrated by Fig. 4 A and 4B.

Fig. 4 A has narrated the another kind of selectable cooker supporting construction of quadrangle periphery 130.It has four supports 157,158,159 and 160 identical, that the shape that resembles inverted " U " is arranged.Every identical support 157 has a horizontal top 157a and the identical first and second downward structures (all not having expression among the figure).When using this to support 157, the first downward structure is to be inserted into second group of first plate 132 fixing with structure 163 and position fixing with (not drawing among the figure) in the structure down than the upper part, and the second downward structure is to be inserted into first group of second plate 132 fixing with structure 162 and position fixing with (not demonstration among the figure) in the structure down than the upper part.The horizontal top 157a of such first support 157 and adjacent first and second plates, two top margins 138 are formed on a right angle triangle of the northwest corner of periphery 130, and wherein laterally top 157a is the hypotenuse of triangle perpendicular type.

According to identical order, the horizontal top 158a of second cooker support 158 is the hypotenuses at the right angled triangle of the northeast corner of quadrangle wall 130.The horizontal top 159a of the 3rd support 159 is the hypotenuses at the right angled triangle of southeast corner.The horizontal top 160a of the 4th support 160 is the hypotenuses at the right angled triangle of southwest corner.Horizontal like this top 157a, 158a, 159a and 160a form a tetragonal structure and support undersized cooker.

Shown in Fig. 4 B, also has another additional cooker supporting construction.It supports 157 ', 158 ', 159 ' and 160 ' by four cookers identical, that the shape that resembles inverted " U " is arranged and forms.This structure of being narrated by Fig. 4 B with the object structures of being narrated by Fig. 4 A roughly the same.Only among Fig. 4 B, to support 157 ' top 157 ' a be the transversary of crooked 90 degree to cooker, it is different from the rectilinear horizontal top 157a among Fig. 4 A.Have the crooked horizontal top 157 ' a of 90 degree like this, 158 ' a, the cross that 159 ' a and 160 ' a form a hollow supports the small size cooker.

Though be appreciated that Fig. 4,4A and 4B have showed that the additional cooker of numerous forms supports, and the variation of spiritual and purpose, this form is hard-core according to the present invention.In fact, it all is suitable that the cooker of any form supports, as long as it is detachable, can fixingly is installed in quadrangle with structure and places outward by using again.

Fix with structure 162,164,163 and 165 in addition and can be positioned in every on the medial surface 136 or lateral surface 134 of upper sheet space.Also have according to spirit of the present invention and purpose, identical at least one fixedly structure of usefulness can be arranged on upper sheet space 132 at every.

Fig. 5 has illustrated that using first kind of enforcement of the present invention can control the device that flame heat regulating transmits.The boiler face 166 that the hollow inner disc 102 of loop concave at first is positioned in gas furnace gets on around the superstructure 178 of a burner.Tetragonal peripheral 130 are positioned in boiler face 166 again gets on around this inner disc.Such arrangement makes that the rotating shaft 114 of inner disc is consistent with symmetry axis 142 coincidences of quadrangle periphery, and has aimed at the center of superstructure top cover 180.The combustion gas spout 182 that divides numerous side direction of Fabric along circumference is arranged on the ringwall of this top cover 180.In addition, a bottom surface 174 with cooker 168 of cylindrical outer surface 176 is to be placed on peripheral each to extend upward on the top 152 of structure 146.Under such arrangement, the position in garden, the top week 110 of inner disc 102 is the positions that are higher than the superstructure top cover 180 of burner, and peripheral 130 quadrangle top margin 138 is be placed equally high with garden, the top week 110 of inner disc 102 at least.

By extending upward the gap 172 between the bottom surface 174 of tetragonal top margin 138 and cooker that structure 146 caused enough height are arranged in addition.This gap 172 allows outwards to be flowed out by the waste gas of the heat of flame combustion generation and air with not stopped, and continues to make progress mobile along the outer surface 176 of cooker.So just can come heating cooker 168 by the heating outer surface.Can imagine that owing to exist sufficiently high gap 172 just can not produce an outside pressure with regard to the hot gas, this outside pressure can make flame ejection gap 172 and cause flame to burn outside the gap.As at that rate, the flame outside the quadrangle exterior wall can not farthest be used for to the heating of cooker 168.Therefore, to be with the structure 146 that extends upward of enough height outward be very heavy for the efficiency of heating surface that improves when the cooking to quadrangle.

The theory of flame thinks that the highest temperature is arranged at its top.Minimum temperature is arranged at its bottom, and exists the core of flame there.Under being participation at oxygen, the burning of fuel gas in the core of flame takes place.According to the description to gas range burner frame for movement that is seen everywhere, the core of flame is the spout that is connecting burner in addition, because flowed out the burning mixture that pressure is arranged there.In by aforesaid air theory, the surrounding air with lower temperature has bigger proportion in addition, and it by at lower position, space, goes participate in flame burning from flowing to the bottom of flame of flame as auxiliary air all around.

Detachable of the present invention can be controlled first kind of enforcement of the device of flame heat regulating transmission and follow these well-known flame theories just, and the kenel by control radiation of flame heat regulating and convection current obtains the high efficiency of heating surface when the cooking.

Fig. 5 has also set forth the convection of heat of being controlled by inner disc 102 and has comprised cross-ventilated kenel.Auxiliary air 190 with minimum temperature goes to get involved flame burning from 198 bottoms 188 that flow to flame 184 all around of burner.This auxiliary air 190 is the hole 144 by quadrangle periphery 130 at first, main and then by divide Fabric inner disc 102 down the position near the hole 116 of the intensive minute Fabric in garden, bottom week 112.

The air that part enters inner disc 102 has participated in forming flame from the burning of the burning mixture 183 of burner head ejection, and the burning that produces flame waste gas is the top 186 of continuously carrying out until flame 184.As shown in the figure, the top 186 of flame is under the bottom surface 174 of cooker.A part enters the air 190 of inner disc and does not get involved burning, continues then upwards to flow but be heated, and becomes the air 196 with maximum temperature.This temperature is identical with the temperature that burning produces waste gas.Under this situation, heat the bottom surface 174 of cooker earlier at the hottest air 196 and the top of flame 186.The waste gas 189 that the hottest then air 196 and flame combustion produce outwards flows out by gap 172 from the top 186 of flame, continues upwards along the cylindrical outer surface 176 of cooker mobile and away from flame 184.Simultaneously it is also by to the heating of cooking utensils outer surface and to the heating of cooker 168.When the cooking, can reach high efficiency heating like this by the kenel of control convection of heat.And in this controlled convection of heat, the flowing of the hottest air and waste gas, the bottom surface 174 and the outer surface 176 that all are centered around cooker carry out,

When estimating above-mentioned flame convection of heat to the contribution of high efficiency heating, the inner disc 102 of loop concave mesopore of the present invention has greatly been controlled the flame convection of heat and has been comprised cross-ventilated kenel.First dense distribution is at inner disc 102 hole at positions down, and the superstructure 178 that the auxiliary air 190 of lower temperature is flowed to burner provides less flow resistance.Oxygen in this auxiliary air is absolutely necessary to the formed flame burning of burning mixture, and it also helps to reach the completing combustion of fuel gas.It two is that the air 196 of the heat in inner disc and waste gas 189 that burning produces are surrounded by inner disc 102, and is forced to flow upward.They at first to bottom surface 174 heating of cooker, flow out cooking utensils outer surface 176 heating by gap 172 then continuously.

The kenel of this controlled convection of heat is extremely important for the high efficiency of heating surface that will obtain when cooking, and particularly has only under the situation of very limited spatial altitude between the bottom surface 174 of burner top cover 180 and cooker.The burning mixture that pressure and high flow rate are arranged 183 of ejection combines with oxygen in the auxiliary air at once and burns from the spout 182 of burner.The flame waste gas of its generation has make progress high-speed, but the bottom surface of cooker 174 has stopped the approach that upwards flows of the thermal current that comprises waste gas and air.In this case, the feature of the free convection of normal foregoing flame is understood destroyed and is caused most hot gas laterally outwards to flow.There is the hot gas of part to move towards boiler face 166 simultaneously downwards.If do not settle loop concave mesopore inner disc 102 of the present invention like this on the boiler face, will cause the low efficiency of heating surface, and become sharp contrast with the obtained high efficiency of heating surface of the present invention to cooker.

What can also confirm in addition is, except the kenel of above-mentioned convection of heat by inner disc 102 controls, also the high efficiency of heating surface has been played important contribution by the gap 172 of the peripheral 130 enough height that provide.Because obtained controlled flame heat and cross-ventilated kenel have been facilitated in gap 172 that should enough height.

Except the kenel of control convection of heat, inner disc 102 of the present invention also can be controlled the thermal-radiating kenel of narrating as preceding.The radiation of heat of this control is also worked to the efficient heating in the cooking.

In addition, well-known thermal-radiating emission is always pointed to the surrounding environment that it has lower temperature from an object with higher temperature.So the outer surface 106 of heated loop concave mesopore inner disc is always outwards launched heat radiation in the cooking.But since exist tetragonal peripheral 130, because of it has centered on inner disc 102, thus by the outside heat radiations of the outer surface 106 of inner disc by peripheral 130 stopped.Peripheral like this 130 just help to maintain high temperature in superstructure 178 peripheral regions of burner as an insulated wall, yet this described zone all is to be under the cooker 168, and the 130 pairs of high efficiencies of heating surface in quadrangle periphery have additional contribution like this.

More than the principle of the high efficiency of heating surface that can be obtained by apparatus of the present invention being explained in when cooking of narration can be confirmed by the result of test.The result of this test exemplifies illustration (I) part in present patent application.

Can see that from the above disclosed first concrete structure of implementing its structure can have multiple variation in addition, such as a crimping or the limit is minor official can be added in the collar 110 of inner disc and the mechanical strength that inner disc 102 is strengthened in foundation ring 112.

Not to be restricted to only be the structure of annular to this inner disc 102 simultaneously.In fact any symmetrical structure shape all is suitable.For example, the inner disc 102 of this loop concave hollow can be polygonal, such as quadrangle, pentagon, hexagon etc.Same reason, quadrangle periphery 130 also can be the polygonal of any symmetry.

By shown in Figure 7, it has explained orally the distortion 132 ' of upwards settling plate 132.The plate of upwards settling 132 in disclosed of the present invention first concrete the enforcement, this is deformed into a rare downward pillar 139, and it is to be placed on each base 140 ' of upwards settling plate 132 '.This pillar 139 is in order to supporting this plate 132 ', thereby supports whole periphery.In addition, a super heated rubber part 141 can be installed in the bottom of each pillar 139, and the smooth surface in order to the protection boiler face makes it avoid frictionally damage.

Of the present inventionly can control device that flame heat regulating transmits 100 included annular indent mesopore inner disc 102 and quadrangle periphery 130 the most handy durable metal or metal alloys, comprise that iron and steel make, in addition, can do suitable surface treatment to the surfaces externally and internally 108 and 106 of inner disc, comprise face coat.Surface treatment helps the control to the kenel of heat radiation and convection current, and the durability that increases this device.Surface treatment can comprise method chemistry, electrochemical or ceramic.The color on the surface of handling is black or white preferably.The inner surface and the outer surface 136 and 134 of same quadrangle periphery also can be done same surface treatment.

Fig. 6 has described the of the present invention second concrete enforcement 200, and it has comprised the inner disc 202 and the annular periphery 230 of the loop concave of hollow.

Can confirm that the inner disc 202 of this hollow ring concave surface is with inner disc 102 striking resemblances in first concrete the enforcement, so each architectural feature of this inner disc 202 can not narrated again.Its architectural feature is by the digital representative that 3 figure places are arranged.It is same as the same structure in first concrete the enforcement for a structure, describes digital identical in first and second numeral and first enforcement in the middle of the numeral of this structure.Different is that tertiary numeral is to be replaced with 200, rather than in first implements 100.

As described in Figure, the height of annular peripheral 230 is " H12 ".It also has an outer surface 234, inner surface 236, the top margin in garden, top week 238 and the base in garden, bottom week 240 and a rotating shaft 242 that they are common.When combination, this rotating shaft 242 overlaps consistent with the rotating shaft 214 of inner disc.Moreover numerous holes 244 divides Fabric equably and penetrates this periphery 230.According to spirit of the present invention and purpose, be number more than hole on inner disc 202 at the number of hole on the annular peripheral 230.

Having three on this peripheral top margin 238 at least, identical Fabric's extend upward structure 246 by dividing uniformly in garden week.This structure 246 has horizontal top 252 and has first and second sides 248 and 250 that make progress of equal height " H13 ".Certainly the height " H13 " of this side is to be designed to be lower than peripheral height " H12 ".In addition, the length that extends upward the horizontal top 252 of structure is longer than the length of dual- side 248 and 250.

Each identical extended structure 246 has following three functions like this: the firstth, and support has the cooker of flat or sunken bottom; The secondth, provide one outwards and the approach that upwards flows to the hot-fluid of the waste gas that comprises flame and air; The 3rd is to come the block heat may be to the heating of cooker handle as a thermal resistance plate.Be understandable that in addition this periphery 230 must have at least three extensions that make progress to support cooker flat or sunken bottom.

Should outer be with the fixedly structure of usefulness.Fig. 6 has narrated fixing with structure 262 and fixing with structure (not drawing among the figure) at position down than the upper part that divides Fabric first group on annular peripheral inner surface 236, for example likes semicircular hook.Two fixing with structure be positioned to be parallel to and to right-hand near a median vertical line 247 that extends upward structure 246.In addition, structure 262 is to approach peripheral top margin 238, and the fixing of position approaches peripheral base 240 with structure under.Same second group be in than the upper part fixing with structure 263 and down the fixing of position be to be placed to be parallel to and with structure (not drawing among the figure) to close this median vertical line 247 of left.Structure 263 is positioned to again and approaches top margin 238.The fixing of position is to approach base 240 with structure under.

This comprise semicircle hook fixing is to be used for fixing three identical cookers that add to support 256,258 and 260 on annular peripheral 230 with structure.Undersized cooker can be placed in the additional support when the cooking like this.As can be seen from Figure 6, first cooker supports 256 the shape that resembles inverted " U ", and a horizontal top 256a and the identical first downward structure 256b and the second downward structure (not drawing among the figure) are arranged.

When installation first cooker supported 256, the first downward structure 256b of this support at first was inserted in second group two fixing using in the structure that extend upward structure 246 near first.The second downward structure is to be inserted near second to extend upward 246 first group two fixing using in the structure then.Shown in figure, second extends upward 246 and is arranged in first in the direction of the clock and extends upward after 246.Similarly, the second and the 3rd cooker support 258 and 260 also can so be installed.Their horizontal top 256a, 258a and 260a have formed the supporting construction of an equilateral triangle, can place undersized cooker easily in leg-of-mutton top like this.

Mandatory declaration be, be positioned near each upwardly extending median vertical line 247 with structure fixing, just can obtain the cooker supporting construction of the equilateral triangle of a minimum dimension.Littler like this cooker can be placed on this minimum triangular structure above.

Obviously, thisly fixingly can be placed on peripheral 230 Anywhere, so long as can fixingly justify the additional support of deciding cooker by these with structure with structure.In addition, each group is fixing can contain at least one structure with structure.

Owing to there is first and second groups the fixing structure of using, multiple additional cooker supports and can be formed by the example conversion of above narration, and one of them is identical with the structure of describing among Fig. 4.So description that the disclosure is no longer done to repeat to them.

Also have, as pillar shown in Figure 7 139 and rubber parts 141, periphery 230 also can have on base 240 in order to support three the downward pillars and the corresponding super heated rubber part in the bottom of peripheral and protection boiler face at least.

Example (I)

Following discloses be that the present invention is used in the example on the gas burner burner.It only is in order to confirm that above-mentioned the present invention can improve the elaboration of the efficiency of heating surface that this example is provided, rather than for restriction of the present invention.

(1) makes the device that to control the flame heat regulating transmission.

One can control the device of flame heat regulating transmission according to the of the present invention first concrete made of implementing.Its inner disc 102 and peripheral 130 of quadrangle by a loop concave mesopore is formed.Inner disc has the circumference 110 of a top end opening, and the diameter of its circumference length of side is about the circumference 112 of 19.3 centimetres and a bottom end opening, and the diameter of its circumference length of side is about 7.3 centimetres.The difference in height of two garden peripheries is 3 centimetres.

Two groups of cavities 116 of running through inner disc are formed by boring, and the aperture is about 6 millimeters.First group hole divides Fabric to be on inner disc is about 18.2 centimetres than the diameter of upper position the circumference 118 at one equably, and this circumference is lower than 110 1 centimetres of inner disc top circumference.The distance in adjacent two holes is about 3 centimetres on circumference 118.Second group hole is to divide Fabric to be about at a diameter than the bottom on 15 centimetres the circumference 120 equably by circumference, and its bottom circumference 112 that is higher than inner disc is about 0.7 centimetre.Distance between adjacent two holes on garden week 120 is about 1.5 centimetres.

(4) Ce Shi result.

Table one: to the result of experiment and check sample test

Listed the result of test successively by table one.It has proved than using the needed time of commercial gas burner, has used device of the present invention back the heating of the cooker of less and larger container has all been improved the efficiency of heating surface more than 14.6 at least percent.The result who increases the efficiency of heating surface proves that for saving fuel gas, the heat radiation of control flame and the kenel of convection current are vital.The result of test also proves simultaneously, has used the device that can control the flame heat regulating transmission of the present invention greatly to reduce fuel gas that is consumed and the carbon dioxide that greenhouse effects are arranged that is produced when the cooking.

In above-mentioned open expression, the of the present invention first and second concrete argumentations of implementing be at boiler face the gas burner of closed type combusting device structure is installed.Yet can determine that the present invention also is suitable for the gas burner that boiler face is equipped with the open-type burner structure.

In addition, according to spirit of the present invention and purpose, the periphery 130 or 230 of the control device that heat is transmitted can be the structure of a prolongation, and it can be used for around 2 gas burners that are arranged side by side.

According to spirit of the present invention and purpose, the inner disc 102 of this device or 202 and pairing peripheral 130 or 230 can be made into integrated again.For the structure of incorporate inner disc 102 and peripheral 130,110 whiles of garden, top week of inner disc are connected to upper sheet space 132 with each of periphery.Its junction 137 as described in Figure 4, be at each on upper sheet space inner surface 136.This junction 137 is positioned to the median vertical line of upper sheet space 132 and is lower than the intersection of the parallel lines of its top margin 138 slightly.After integrated, the rotating shaft 114 and the peripheral symmetry axis 142 of inner disc coincide.Inner disc 102 and peripheral 130 can both stand on the boiler face separately like this.

For the second concrete incorporate structure of implementing, the top circumference 210 of inner disc 202 is to be connected on the circumference than the upper part that is in peripheral 230 inner surfaces 236.This circumference is parallel to peripheral top margin circumference 238, and the rotating shaft 214 of inner disc and peripheral rotating shaft 242 coincide like this.In addition, incorporate model can have the change on the more structural.

A kind of change is periphery 130 or 230 to be dwindled into the parts of a plurality of support cookers.These numerous parts have the support cooker, and preventing provides a function that outwards reaches the gap of upwards leaving away to the heating of cooker handle with to hot gas.Under this principle,, can dwindle into and have at least three identical upwards fillets such as the periphery 230 of square peripheral 130 or annular.They are according to all uniformly-spaced being connected with the inner disc of annular, and each fillet has the horizontal top 152 of equal length.In addition, each fillet has upper sheet space 132 maximum height equally in the same way, and its bottom is to be supported on the boiler face simultaneously.The top of such three fillets can be used for supporting a cooker bottom surface, and prevents the heating to the cooker handle.

Will also be appreciated that in addition the device of control flame heat regulating of the present invention transmission only includes the inner disc of annular surface hollow.Under this structure, this inner disc is to be placed on the superstructure that centers on a flame burner of gas burner on the boiler face, and existing commercialization fence is used to support cooker.

As for selecting which type of material to make this device with, ceramic material also is a suitable selection.Comprising aluminium oxide, silicon nitride, carborundum, titanium carbide, magnesia and silica, or their combination.Selecting ceramic material is because it has good thermal property, comprises high melting point, big thermal capacity, low thermal conductivity and heat expansion.It also has the favorable mechanical performance and comprises hardness, and compression strength and corrosion resistance are in interior durability.In addition, the fracture toughness of ceramic material can be improved greatly by fibre-reinforced ceramic composite, and this composite has been used fibre-reinforced manufacturing process and made.These character of ceramic material are satisfied with making the requirement of this device material requested.

Like this, for the high temperature that maintains following space, cooker bottom, comprise inner disc and the peripheral device made of ceramic material have positive effect.This also has superiority to the high efficiency of heating surface when cooking that the present invention will obtain.

(II) has the burner of fuel gas of (outward) pyrosphere of novel jet nozzle passage and suitable dimension.

Be appreciated that above disclosed device is to combine existing burner with fuel gas of sideward directed spout.The architectural feature of this kind spout is narrated in above " narration prior art " joint.Two kinds of main shortcomings of spout have also been narrated in addition and for the negative effect that the high efficiency of heating surface had that will obtain, comprising the phenomenon of the most extreme flame extending transversely when burning mixture has maximum stream flow (pressure) especially.

Like this, for most widely used general and most probable the high efficiency of heating surface that will obtain when being used the cooker of size, particularly again when application has the flame that burning mixture produced of maximum pressure, a kind of suitable countermeasure of the present invention is exactly to allow flame go burning along one with respect to horizontal angle direction.In this state, the flame burning direction is the direction from the through bottom surface to cooker of the spout of the fuel gas of correspondence, and the top of flame is directly to have contacted the cooker bottom surface.The shortcoming that has comprised large-area cold temperature area and cooling effect that phenomenon caused that this flame of just having eliminated existing burner prolongs to horizontal direction.Under this countermeasure, the present invention has changed the structure that existing commercial burner nozzle comprises their sensing.

Fig. 8 has shown the superstructure 300 of burner of the present invention, and it has numerous novel fuel gas spout passages 314.This superstructure 300 that is placed on the gas furnace furnace table surface is made up of dismountable garden lid 302 and one hollow stem that makes progress 340 that is fixed on the furnace table surface 166 at a top.And the arrangement of garden lid 302 is the necks 340 of this hollow that coincide to getting off.

This garden is stamped a horizontal top 304 and has been connected a downward annular sidewall 306, thereby has at the inner interior concave space 330 under shed of garden lid.This abutment wall has the bottom surface 312 of outside anchor ring 308, interior side ring surface 310 and annular.In addition, also has numerous vertical slots 314 under shed.Vertical slot radially arranges and has cut the part abutment wall 306 of the garden ring 312 that comprises lid bottom, garden by the circumference of garden bezel ring, wall.Should hollow stem 340 upwards be the annular walls 342 that contain a middle blast tube 344 and garden, top ring 346.The annulus 346 on its top matches with garden, the end ring 312 of garden lid 302.The center-aisle 344 of this neck can be connected with the interior concave space 330 of garden lid like this.This center-aisle 344 is to be used for the fuel gas by having pressure and the mist 360 of primary air.

Shown in Fig. 8 and Fig. 8 A, this novel burner nozzle passage derives from the vertical slot 314 under shed with narrow width.It is one less to one of inner opening 322 less space 314b that vertical slot has the bigger space 314a of expansion gradually with a bigger outside opening 326 to connect to have.This less space has the symmetry axis 332 of a side direction.This outside opening 326 and inside opening 332 are to be placed in respectively on the lateral surface 308 and medial surface 310 of annular sidewall.

The space 314a of this expansion also has the transversely arranged downward bottom opening 318 and identical downward two sides of the inner surface that points to obliquely upward 316, that is represented as the top.Like this, be reference with the symmetry axis 322 of this less space 314b, the top inner surface 316 that this oblique upper points to has an angle " D ".In an embodiment preferred, this angle " D " is 45 degree.In addition these downward two sides have as shown in Fig. 8 A, should be than shape of the right-angled trapezium of the vertical cross section of large space 314a.This less space 314b has one to be represented as the rectangle inner surface 324 and the two downward sides 328 on top, and then forms downward opening 320.

Continuation is by shown in Fig. 8 and Fig. 8 A, is in the lateral surface 308 that high-end side 316a has connected top cover ringwall 306 than one of the inner surface 316 of large space.The side 316b of another low side has connected the inner top surface 324 of less space 314b.Under this structure, the length of inner top surface 324 has been represented the width of this vertical slot 314.In addition, should be than the bottom end opening that has formed vertical slot 314 under shed 320 that has laterally connected this less space 314b of large space 314a under shed 318, it has radially cut garden, the end ring 312 of top cover 302.

Like this, when top cover 302 be positioned to match with hollow stem 340 after, those vertical slots just are converted into corresponding novel gas spout passage 314 of the present invention, and wherein the outside opening of vertical slot is exactly the outside gas vent 326 of passage, and vertical slot is exactly the gas feed 322 of passage to inner opening.

As seen from Figure 8, enter into an internal cavity of the burner superstructure of mainly forming when burning mixture 360 after by the interior concave space 330 of garden lid 302 with pressure, this has the gas 360 of pressure at first to pass through the less space 314b of the novel passage of the present invention, enters into the bigger space 314a of expansion gradually then.The sensing of wherein less space 314b is consistent with the sensing of the symmetry axis 322 of side direction.

According to hydromechanical principle, be appreciated that to such an extent that be, when the burning mixture 360 of the centre gangway 344 that enters neck has the selected pressure (or flow velocity) of gas burner user, burning mixture 360 has flow velocity faster in less space 314b, and it has slack-off gradually slower flow velocity in big extending space.This is because of the less vertical section than less space 314b, should have and the bigger vertical section that enlarges gradually that exports 326 plane parallel than large space 314a.This structure leading down, can draw into mist and in than large space 314a, have steady flow than jogging speed.On gas outlet 326 positions of this gas, just formed stable flame kernel when lighting like this by an electronic ignition device (not having to show) at novel jet nozzle passage 314.

In addition, the hole that has passed through to control the flame heat regulating transfer device from the auxiliary air of flame surrounding space participates in flame burning, and promptly it has also supported to form this stable flame kernel.The present invention like this when the burning mixture of supplying with has maximum pressure, can be formed with the flame of stable center especially.

It must be understood that again, the preferred angle of 45 degree that the burning meeting of flame kernel is had along the inner surface 316 of novel passage 314, this has also just guided the whole flame also can be along this angle direction burning.When the cooking, heating cooker is effectively come in the bottom surface that this flame that has angle to point to will directly touch cooker.This reasoning can be confirmed by the experimental result of enumerating in the following table two.

Example (II)

Following discloses be that the present invention is used in the example on the gas burner burner.It only is in order to confirm that above-mentioned the present invention can improve the elaboration of the efficiency of heating surface that this example is provided, rather than for restriction of the present invention.

According to the above-mentioned architectural feature in Fig. 8 and 8A, the present invention has made a top cover 302 with 32 new gas spout passages 314.The height of this top cover is 1.1 centimetres.The diameter of its outer ring surface 308 is 6.4 centimetres, and the diameter of inner ring surface 310 is 5.1 centimetres, and promptly annular sidewall thickness is 0.65 centimetre.Wherein the diameter of the high and inner ring surface of top cover is identical with the diameter of the height of existing goods top cover and inner ring surface, and this commodity top cover has 24 laterally square type spouts of sensings.Novel jet nozzle width of channel 324 is about 0.3 centimetre, and the height of its outside opening 326 is about 0.5 centimetre, and it is about 0.5 centimetre than large space 314a bottom to the length of under shed 318.In addition, the length to downside 328 of less space 314b is about 0.15 centimetre, equals the height of this less space 314b.And the width of the inner top surface 324 in this space and bottom end opening is about 0.3 centimetre, promptly is the width of this less space 314b.

Like this, 32 air inlets 322 with said structure on top cover 302 have altogether and are about 1.44 square centimeters area, and the gross area of 24 square air inlets of this quadrature and commodity top cover is close (being about 0.25 centimetre of size that multiply by 0.25 centimetre because of its each square air inlet has) for 1.50 square centimeters.The flow velocity of 24 air inlets that the flow velocity that the burning mixture 360 that ought have a pressure like this flows into 32 air inlets 322 making top covers 302 and the mist with uniform pressure flow into the commodity top cover is approaching identical.

In addition, the experimental procedure in example (II) with those in example (I), exemplify basic identical, only early the time finishes in the afternoon in the experiment of example (II).In this period, the variation of the town gas pressure of the use of can ignoring.

In addition, other different experimental status is as follows:

(1) only uses hollow inner disc 102 in example (I) separately, only used employed teapot in example (I) again.Therefore the prolongation fence of marketable coal steam stove is to be used for supporting this teapot.Be about 3 centimetres by the upper topside 316a of novel jet nozzle passage gas outlet 326 to the distance of teapot bottom surface like this.

(2) in test, the mist after the fuel gas that the city that having used has maximum pressure (flow) is supplied with to mix with an air, its correspondence commercial gas flow control handle point to a mark " HI " on the gas burner table top.And the combustible gas of determining this use have maximum pressure (flow) be according to control handle be in a latched position of formulating by knob manufacturer and judge.

(3) Ce Shi order is to measure check sample twice earlier, has used the top cover (simply being C-Cap) of commercial manufacturing at that time.Experiments of measuring sample again, the top cover (simply being I-Cap) that has used the present invention to make at that time.

In the test experiments sample, can be observed the stable and intense flame that has generated.This flame and horizontal direction are into about the angle that is 45 degree, and the top of flame directly touches the bottom surface of kettle.Has drawn into a pyrosphere at the top of the flame that comes from 32 novel jet nozzle passages 314 like this.Its diameter is about 13 centimetres, is significantly less than 19.3 centimetres of the diameters of teapot bottom surface.And the top of the flame that forms from the novel jet nozzle passage at first from oblique upper behind the bottom surface that has contacted kettle, change radially horizontal branch Fabric then into and draw into the garden ring of a flame.The garden ring of this flame continues to contact till it disappears with the bottom surface of kettle.The flame that the traditional spout from the commodity top cover in contrast generates has presented in corresponding prolongation in a lateral direction.This kind flame almost is parallel with corresponding horizontal direction, and the top of flame does not directly touch the bottom surface of kettle.

The experimental result of enumerating in table two proves, uses inner disc of the present invention to combine with the burner with novel jet nozzle passage to obtain to improve percent 10.91 the efficiency of heating surface.This efficient be sure of, particularly according to only having the fact of very little percentage error percent 0.6 as the result of twice sample for reference of test.

Table two: to the result of experiment sample (I-Cap) and check sample (C-Cap) test

Be appreciated that what have the expansion of pointing to oblique upper inner surface 316 not only changes the flow velocity that has delayed burning mixture than large space 314a, but also has changed the flow direction of burning mixture.Make it from the angle direction during to the space 314a of expansion with respect to the zero degree angle to 45 of horizontal direction degree by admission space 314b.So for the present invention, the other technologies scheme that changes gas flow by the sensing that changes admission space 314b also exists.Below having under the purpose of flows at angles in order to obtain burning mixture, all schemes that are different from above disclosed scheme are discussed.

Fig. 8 B discloses and has been different from another embodiment 314 ' the spout passage 314 shown in Fig. 8 A, novel jet nozzle passage of the present invention.In this scheme, the sensing of admission space 314 ' b has an angle " G " with respect to horizontal direction.This angle can be represented by its symmetry axis 332 '.Accordingly, this spout passage 314 ' has just become a through hole that penetrates top cover ringwall 306.Like this this more gradually the basal surface 318 ' of extending space 314 ' a with respect to the base ring face of top cover one angle " E " is arranged.And the sensing oblique upper in this space has an angle " F " as the inner surface 316 ' of top cover.As seen from the figure, angle " F " is greater than angle " E ".According to this architectural feature, be appreciated that according to spirit of the present invention and purpose, in any case change the orientation angle of less admission space 314 ' b, the gas outlet 326 ' in the space of this bigger expansion must be greater than the air inlet 322 ' in this less space, and angle " F " is always greater than angle " E ", and using this structure is in order to form stable flame kernel.

Also have by shown in Fig. 8 C another novel jet nozzle passage 314 " be up and radially to divide Fabric horizontal top 304 at garden lid 302.Have a upwards symmetry axis 322 " novel jet nozzle passage 314 " by a less space 314 " b connected the space 314 of a bigger expansion " a.Less space 314 as air inlet " b and symmetry axis 322 " direction orientation consistent, it is with respect to one 90 angles of spending are laterally arranged.And the air inlet 322 of this admission space " connected the indent zone 330 of this superstructure ".This expansion than large space 314 " a also is directed upwards towards.It has the 304 lip-deep gas outlets 326 at the top cover top " and two inner surfaces 316 that stretch obliquely upward ".

To the structure type shown in Fig. 8 C, be appreciated that novel jet nozzle passage of the present invention also can have the architectural feature of garden shape from Fig. 8 A.Specifically, the spout passage 314 shown in Fig. 8 C " contain an extending space 314 that inverted symmetrical garden frustum shape arranged " a has connected one coaxially that the less space 314 of garden cylindricality as air inlet arranged " b.And shown spout passage 314 can be by above-mentioned passage 314 in Fig. 8 A " half and the structure of oriented under shed replaced.As for concerning at the spout passage 314 ' shown in Fig. 8 B, this bigger extending space 314 ' a can be the space 314 ' b that an asymmetrical inverted garden frustum has connected a less garden cylindricality.

To Fig. 8 C, the less space that the invention also discloses the novel jet nozzle passage changes the architectural feature of its sensing from Fig. 8 A.This sensing is from changing to 90 degree with respect to horizontal zero degree.The structural change of the position of the change of this sensing is also just corresponding spout passage from the ringwall that is in top cover to the top of top cover.

From an optimized technical scheme, the disposal of this kind spout channel position can reduce three classes: (1) is if the angle in this less space " G " is that this spout passage can be disposed on the ringwall 306 of top cover between zero degree to four 15 degree; (2) if this angle " G " is 45 when spending, this passage can dispose at the top cover top 304 with the intersection of top cover ringwall 306; (3) if this angle is to spend when 90 spend greater than 45, this passage can be disposed the top 304 at top cover.Yet as aforesaid, according to spirit of the present invention and purpose, no matter how this scheme changes the orientation angle in less space and the position of spout passage, this includes an outlet of pointing to the bigger extending space of inner surface obliquely upward must be greater than the import in this less space.

In addition, other structural change also exists.By Fig. 8 A as seen, except connecting the structure of less space 314b by this bigger extending space 314a, this novel jet nozzle passage is the space of this expansion, and promptly the other end 316b of the inner surface 316 that points to of this oblique upper extends and is connected to the inner ring surface 310 of ringwall 306.Like this, this passage is that a space of expanding includes a bigger outlet, the inner surface that a less inlet and points to obliquely upward.

Moreover, except it is disposed the selection on the top cover 302, also this novel jet nozzle passage can be disposed and on the ringwall 342 of hollow stem 340, obtain identical effect.Also have, this novel jet nozzle passage can be disposed simultaneously on top cover 302 and neck 340.In the sort of structure, the spout passage has cut the base ring 312 of top cover and the apical ring 346 of neck simultaneously.Yet being understandable that, these alternative CONSTRUCTED SPECIFICATIONs, is conspicuous for a people with ordinary skill level, so the present invention no longer does the description that repeats to it.

Fig. 8 D discloses the constructional variant of relevant top cover 302.Ring-like laterally projecting limit minor official 344, one garden is to be on the outer ring surface 308 of top cover ringwall 306, and with the hanging at top cover top 304.Minor official bottom surface 348, this limit is garden rings, and it is consistent to the sensing of the interior top end surface 316 that points to obliquely upward with all spout passages 314.During to the angle burning pointed to, just can not change angle along this oblique upper when flame like this because of the influence that is subjected to the minor official existence in this outstanding limit.In addition, an annular groove 346 under shed is to dispose in the junction of this outstanding limit minor official 344 with the top cover ringwall.

Should outstanding limit minor official 344 be design be used for preventing in the cooking if when having soup juice to splash down the phenomenon of the fray-out of flame that may cause.This downward annular groove 346 is to be used for stablizing faint flare.This flare is the burning mixture during by the selected minimum flow velocity of gas burner user (or pressure) and drawing.

Can see,, also can combine simultaneously by the modification of the disclosed cap structure of Fig. 8 D and to draw into a kind of new cap structure with modification by the spout passage shown in Fig. 8 B according to spirit of the present invention and purpose.

Yet, still according to first kind of reason that may cause heat-energy losses in aforementioned chapters and sections " prior art background ", analyzing, can reasoning to a burner (outside) when pyrosphere has oversize, even be when upwards disposing at the spout of this pyrosphere, also can cause the loss of heat energy.Such reasoning is based on the factor of a reality, and the diameter dimension of the cooker that is used has a scope promptly the most general and most probable, for example from 15 centimeters to 20 centimeters.This size has also just determined the optimum size of inner disc 102 or 202 top cover circumference.The device that has the control flame heat regulating transmission of a fixed dimension so just can not stop because the loss of (outward) heat that pyrosphere caused of oversized dimensions.

So, for being intended to obtain the best efficiency of heating surface when cooking, obtaining the size of (outward) pyrosphere, the uniformity of the size in inner disc top garden week and the size of cooker is very important.

The data of the experimental result of following discloses are used for confirming above relevant pyrosphere, the Analysis of Importance of inner disc top and cooker dimensional uniformity coordinated.

Example (III)

Following discloses be that the present invention is used in the example on the gas burner burner.It only is in order to confirm that above-mentioned the present invention can improve the elaboration of the efficiency of heating surface that this example is provided, rather than for restriction of the present invention.

This experiment has used one at made in China gas burner burner with open-type burner by assembling structure.This burner is made up of less central pyrosphere and bigger outer burning ring.Outer burning ring has an annular top cover, and it has overall diameter to be about 10.5 centimeters, and it is 2 centimeters with ring width that interior diameter is about 6.5 centimeters.20 linear openings are arranged on the top cover, its arrange by garden week and radial cuts the top of top cover be used as the gas port that is directed upwards towards.Every linear spout has width, and to be about 0.1 centimeter and length be 2 centimeters.The equivalent inlet-duct area of all 20 spouts is 4 square centimeters like this, under this structure, is 10.5 centimeters along all diameters in the formed garden of the outermost position of each spout.This diameter of 10.5 centimeters also is after burning mixture flows out the spout of outer burning ring, by the diameter of the annular flame that is in outermost position of lighting and forming.

Correspondingly with it be, an annular top cover that is used to test of making has with the identical size of this commodity top cover, but different with its 20 all linear spouts, and experiment has 30 identical upwards spout passages with top cover.They are that to have diameter be that 8 centimeters garden in the middle of one on the top cover top is on week along being arranged in one garden week equidistantly.

Each identical upwards spout passage 314 " have as structure at the disclosed vertical section of Fig. 8 C, it is by the space 314 just as the expansion of an inverted circular cone on top " a connected the space 314 of the garden cylindricality of a bottom " b.The diameter of the garden cylindrical space of this bottom is about 0.4 centimeter, and height is 0.3 centimeter, is the jet pipe of using as air inlet.Its bottom surface 322 " be the air inlet of burning mixture.This upper space 314 " height of a is about 0.2 centimeter.Its top is that diameter is about 0.75 centimeter garden, is used as the gas outlet of spout passage.The extending space 314 of this upper cone platform shape " b is used for reducing the flow through speed in this space of burning mixture.Like this, when having burning mixture than low velocity in shape gas outlet, garden 326 " just formed stable flame kernel when being lighted.

As can be known, have an air inlet 322 of 30 identical spout passages of this structure " area altogether be about 4 square centimeters, the gross area that advances (going out) gas port with the commodity top cover equates.Like this, the speed of burning mixture when it flows into these 20 linear spouts is with the air intake 322 of 30 spout passages of its inflow " time speed identical.This state that is equal to is according to a prerequisite, and promptly when top cover was the top cover of commodity top cover and experiment making, the burning mixture 360 with identical flow velocity (or pressure) flowed into the upwards centre gangway 344 of neck 340.

Experimental procedure in example (III) coexists identical among example (I) and (II) basically.Different: (a) experiment is to carry out having crossed small hours in Chinese Shanghai.This is that the pressure of the town gas of can ignoring changes because finish in the section at that time of experiment; (b) measure the temperature of water with a mercurial thermometer, meter was decided to be the terminal point of test when set water temperature reached 80 degrees centigrade again.

In addition, other relevant experiment situations are as follows:

(1) experiment cooker.

The stainless-steel pan of one garden cylindricality is used as the cooker that is filled with water.It highly is about 15.5 centimeters and diameter and is about 19.7 centimeters.The glass roof of this pot is stamped a central hole.By this central hole, thermometer extend in the pot, till the mercury head of thermometer is immersed in half depth location of water layer.At this moment, will clamp the medium position of thermometer with being placed on rubber stopper on the top cover again.In experiment, be used as the weighing apparatus of institute's water consumption with a bottle.Each water of measuring is that water with a whole bottle comes mark.

(2) make the incorporate device 200 that to control the flame heat regulating transmission.

Make the device that can control the flame heat regulating transmission according to the of the present invention second concrete enforcement 200, it has inner disc 202 and peripheral 230.This inner disc has diameter to be about 18.8 centimeters garden, top week 210, and it is 3.4 centimeters to the height of bottom that diameter is about garden, bottom week 212 of 12.8 centimeters and top.

Three groups of diameters that this inner disc is used as ventilating air in addition are 0.6 centimeter hole 216.Hole in first group is to be distributed in inner disc to be about than a diameter of upper part on garden week 218 of 18 centimeters, is lower than in this garden week inner disc top garden week 210 to be about 0.7 centimeter.Be about 4 centimeters in the distance between adjacent two holes on garden week 218.Hole in second group is that the diameter that is distributed in the inner disc middle part is about 16 centimeters garden on week, and this garden week is higher than 1.3 centimeters of inner disc bottom garden Zhou Yuewei.Be about 2.5 centimeters in the distance between adjacent two holes on this garden, centre week.Hole in the 3rd group be distributed in inner disc down a diameter at position be about on garden week 220 of 14 centimeters, be higher than in this garden week and inner disc bottom garden week 212 be about 0.4 centimeter.Be about 2 centimeters in the distance between adjacent two holes on this low garden week 220.

The height " H12 " of the periphery 230 of this device is about 4 centimeters.Top margin is that diameter is about 18.8 centimeters garden week 238, and its diameter with garden, base week 240 is identical.On peripheral 230, the diameter that has numerous even distributions to be used as ventilating air again is 0.5 centimeter a hole 244.As aforementioned.The number of the hole 244 on peripheral 230 is greater than the number in the cavity on inner disc 202 216.This periphery and have three high be about 1.2 centimeters extend upward structure 246.They are distributed on the peripheral top margin 238 to be used for supporting cooker.In addition, again this inner disc and peripheral corresponding top margin 210 and 238 are fixed together.

In when experiment, will control flame heat regulating transfer device 200 earlier and be placed in the gas burner table top and get on around the superstructure of burner, then bowl is placed on extending upward on the structure of this device.The bottom of a pan face and spout passage gas outlet 326 like this " distance be about 2.3 centimeters, this distance approaches 2.5 centimeters of the distances that measure on marketable coal steam stove structure.

(3) check sample, experiment sample and testing sequence.

Check sample is meant the time of required heating whole bottle water in pot when the structure of commodity in use gas burner.This structure comprise as cooker support to upper supporting column, the little pyrosphere of central authorities and have the outer burning ring of 20 linear opening top covers.Experiment sample one (real one) is meant and is coming around the central authorities and the outer burning ring of marketable coal air burner and when supporting cooker with the flame heat regulating transfer device 200 of controlling of the present invention, the time of required heating whole bottle of water in pot.Experiment sample two (real two) be meant after the top cover of making of the present invention replaces the commodity top cover of outer burning ring, come around gas burner central authorities and outer burning ring and when supporting cooker with the flame heat regulating transfer device 200 can controlled of the present invention again, the time of required heating whole bottle of water in pot.Experiment sample three (real three) be meant after the top cover of making of the present invention has replaced the commodity top cover of outer burning ring, when supporting cooker with former commodity cooker pillar, and the time of the whole bottle water of required heating in pot.

Test is in order: check sample (contrast), real, real two and real three and carry out.

(4) flow velocity (or pressure) of selected burning mixture.

The flow velocity of employed burning mixture (or pressure) is selected by following method in experiment.After the situation of application testing check sample defined, rotate coal gas control handle (on this knob, being carved with lines in advance), make outermost garden that the flame top of outermost touches the cooker bottom surface during week, the flow velocity of flow velocity in whole experiment, using of the fuel gas during then selected this state.Another mark lines are down drawn in the sensing of the mark lines of alignment knob then on furnace table surface.Like this, as long as behind the mark lines that are aligned at the mark lines on the knob on the furnace table surface, just can obtain the flow velocity (or pressure) of identical burning mixture.Also observe the flame situation that is produced during the flame situation that produced approaches to allow at this knob with the flow velocity of experiment usefulness time the maximum gas flow rate in addition.

Only knock down the flame once changes the top cover that original commodity top cover and the present invention make for being used for body in whole experiment.Body changes at the test experiment sample one (real) that finishes and carries out afterwards.In other institutes sometimes, keeping the burning of fuel gas under selected flow velocity always.Reduce the error of the gas speed that may cause like this because of rotation coal gas knob.In the whole process of experiment, correspondingly keep the burning of flame on the little pyrosphere of central authorities in addition always.

Can observe in experiment, the flame that the novel jet nozzle passage on the outer burning ring top cover that the present invention makes is produced has formed a diameter that has that makes progress and has been about 9.5 centimeters flame ringwall.The top of flame had directly contacted the bottom surface of cooker before this, turned to outward direction radially then and the fire ring that forms a transverse plane continues the bottom surface of contact cooker till flame disappears.

In addition, one additional for after confirming to use the present invention, in whether the bottom surface of cooker exists the experiment of significantly " cold temperature area ", observe, the water in pot at first is to come to life along a garden week that is about 9.5 centimeters diameters.Water changes the boiling at the bottom of whole cooker very fast into then.This phenomenon illustrated the bottom of a pan do not have tangible thermograde in the radial direction, neither have the phenomenon of " cold temperature area ".

(5) experimental result

Table three: to the result of experiment sample (reality) and check sample (contrast) test

The experimental result that exemplifies in the table three shows, has used the annular collar with spout passage of the present invention in (real three), and it is percent 18.6 that the previous status of commodity burner (being check sample) has produced significant heat-energy losses.According to the architectural feature of original commodity collar, can analyze, first reason that causes heat-energy losses is the outer burning ring because of oversized dimensions.The diameter of the outermost flame ringwall that the flame of its generation is formed is at least greater than 10.5 centimeters.Second reason is because of its linear spout.

We can say that perhaps the contrast test of being formed from check sample and experiment sample three has shown that suitable pyrosphere size and novel advanced person's spout passage is very necessary for the efficiency of heating surface that improves flame.This novel advanced person's spout passage comprises that the less space with a less air inlet has connected and has big gas outlet and space one of an inner surface that points to obliquely upward bigger expansion.This just makes burning mixture slow down its flow velocity gradually in this extending space.Burning mixture with low flow velocity the gas outlet, again with the participation of auxiliary air under the flame that drawn, than the formed flame of existing goods pyrosphere, can have combustion reaction completely.And then make that formed flame can have higher flame temperature in the experiment sample two (real two) of the annular collar that uses the present invention to make and three (realities three).Caused that like this obvious energy-saving effect is arranged when adding hot water.

If compare with the result of test experiments sample three (real three), test experiments sample two (real two) shown have extra percent 4.1 energy-conservation.This is the contribution owing to apparatus of the present invention, because of it has controlled the kenel of heat radiation and convection current.Meaningfully, than check sample, the test of experiment sample one (real) has shown it almost is identical with percent 4.1 percent 3.9 energy-saving effect.And in the test of experiment sample one and check sample, all related to the upwards form of flame that the existing goods top cover produces.Thereby can conclude, this in experiment sample one percent 3.9 energy-conservation, be to come from the cause of having used apparatus of the present invention 200 equally.

Again from than used apparatus of the present invention at example (I), energy-conservation largely (II) (greater than percent 14.55, with 10.9 percent) with in example (III) by real two with energy-conservation (percent 4) of the real three less degree of comparing, can be clear that, compare with the burner novel jet nozzle passage of the present invention with being directed upwards towards that points to obliquely upward, the spout of sideward directed has caused extremely significant heat-energy losses.

The experimental result of more than enumerating is inferred consistent with the theory according to spirit of the present invention and purpose.Promptly be exactly the efficiency of heating surface that novel jet nozzle passage of the present invention has greatly strengthened flame in the cooking,, thereby prevented a large amount of heat-energy losses because of it has controlled the kenel of flame.In addition, device of the present invention has still been contributed the energy-conservation of part.Like this, result of experiment has just proved that the burner that the novel jet nozzle passage is arranged that the present invention combines with controlled heating capacity transfer device is to obtain a complete technical scheme of the best efficiency of heating surface when cooking.

In addition, it must be understood that from above disclosed experimental result, the present invention can formulate one group of structural coefficient.This group coefficient extremely helps to establish about the device of optimizing structure and the superstructure of burner, again according to having the most extensive and most probable ground is used the size of cooker, thereby obtains the efficiency of heating surface of the best when cooking.This group significant data comprises that the optimization diameter in inner disc top garden week is 19 centimeters, and the diameter in all the pairing one maximum garden weeks of gas port channel outlet on one (outward) pyrosphere is 8 centimeters.And a high some position of the numerical value of these the two kinds of diameters described gas outlet that is corresponding to the optimization distance of cooker bottom surface be 2.5 centimeters to 3 centimeters and the most extensive and most probable the cooker that is used diameter is arranged is 15 centimeters to 20 centimeters.

The maximum garden week that this diameter is 8 centimeters is according to result in example (III) and reasoning.This garden week is along producing upwards each novel jet nozzle passage gas outlet 326 of combustion flame at outer burning ring " center 322 " formed.Yet it must be understood that this maximum gauge also is applicable to one (outward) pyrosphere for 8 centimeters.It is just like the spout passage 314 of the outlet 326 described in Fig. 8 A, and these spout passages of disposing on the ringwall of burner superstructure have been controlled the miter angle degree with respect to horizontal direction that flame had.Condition when having maximum pressure (or flow velocity) according to 2.5 centimeters to 3 centimeters of above-mentioned optimization distances and burning mixture again, the collar diameter that can expect the wall with flues that an annular of generation points to obliquely upward is about 14 centimeters.14 centimeters diameter of this expectation is still less than above specified most probable be used 15 centimeters to 20 centimeters diameter of cooker the most widely.Like this, still, can heat the cooker of this kind selected size efficiently.

Moreover, must be clear that, wait until in the cooking, having that the burning mixture of elevated pressures is used by the most extensive and most probable ground.The diameter on the ring-like wall with flues of this kind that is produced top can be less than 14 centimeters that estimate at that time.Can expection obtain gratifying energy-saving effect like this.This prediction is to have prevented additionally that according to the inner disc that is provided in the example (I) experimental result of the loss of heat energy from coming reasoning.

Also have to have for a short time during at burning mixture, also can expect satisfied energy-saving effect to middle pressure.Because this time, device of the present invention is the loss that has prevented heat energy fairly obviously.

People also it must be understood that, if according to above-mentioned coefficient sets (disregarding the coefficient of cooker), and when having used the Chinese style frying pan with protruding bottom, also can expect to obtain gratifying energy-saving effect.This be because, the less floor space that is had with the garden cylindrical pot and having in the architectural features that are connected of 90 degree of basal surface and lateral surface is compared, the outer surface of frying pan has bigger area and smooth curve usually.Like this, after having used the present invention and the burner that the novel jet nozzle passage is arranged that controlled heating capacity transfer device combines, according to hydromechanical principle, after flame directly touches frying pan, all can flow along the outstanding outer surface of frying pan or burning through the waste gas with higher temperature of burning generation and the top of air and flame.Frying pan will be heated effectively like this.

After having determined above-mentioned coefficient sets, also must see the chance of optimizing other structural coefficients in addition.Adjust those outlets and size inlet such as picture, and the sensing of regulating the big extending space of spout passage, obtain a kind of energy-saving effect of the best.
