United States Patent (USP) numbering 6,851,420 is issued to Jie Nisi (Jie Nisi patent) " burner with directed spout " by name on February 8th, 2005 and discloses an improved burner, and it has some identical structure divisions.Burner nozzle in each several part is all parallel and crossing with the direction of a setting.
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 and the method for mixing of control auxiliary air.
In addition, well-known gas burner with two to three flame combustion circles is arranged also, numerous traditional lateral gas spouts are all arranged on each burning ring.For example United States Patent (USP) numbering 6,132,205 was issued to " the enclosed gas burner with a plurality of burning ring " by name of Mike Hallett on October 17th, 2000.Two burning ring that are in the center of this burner are used to heat.And the 3rd be in peripheral burning ring, under other burning ring collaborative, is used to cooking food.
The gas furnace of current family expenses according to the mounting structure of burner on furnace table surface, can be divided into the assembling of the burner of fully closed and open-type.Before a kind of described assembling can describe 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 " and second patent number 6,505,621st, be issued to be called " device of totally-enclosed gas burner " of kind ripple door on January 14th, 2003.
From the device relevant for gas furnace for cooking of above narration, can know in existing technology, also to have lacked a kind of flame heat regulating of controlling directionally from flame burner to the device of the transmission of cooker in use.This device is a detachable, can be placed on the table top of gas furnace around the superstructure of a burner, supports a cooker simultaneously again.When the cooking, can fully be controlled from the heat radiation of flame generation and the form of thermal convection current like this, promptly this device can focus on heat on the cooker, improves the efficiency of heating surface to cooker from the loss that prevents heat.For this purpose, United States Patent (USP) 7,708,006 (006 patent) discloses the device that the flame heat regulating controlled of a kind of detachable of this invention transmits.This invention has also proved after using this device and existing burner with gas spout of sideward directed matches with experimental result, can when the cooking, increase the efficiency of heating surface of flame significantly.
Yet, must be clear and definite be, to use this device and be a passive scheme for reaching the purpose that increases the efficiency of heating surface.This is meant that this device just is to control the heat that generates flame to energy-conservation contribution and transmits.
Patent by above-mentioned Jie Nisi and Mike Hallett can know, and is popular in the western market normally circular, or the gas spout of rectangular side direction.These spouts radially are distributed in the periphery of a burning ring.Like this, use burners in prior and just caused mixed combustible gas body phenomenon to each lateral flow after going out many spouts of burner.Thereby the corresponding flame kernel that forms at each spout place is also towards corresponding side direction burning.When certain this phenomenon is the most tangible, be that the combustion gas in the mist at spout place has by in the selected Peak Flow Rate of the user of gas furnace (or pressure).
Visible by the Fig. 2 in the Jie Nisi patent and 2a again, when the top and the spout of flame have one apart from the time, the top of flame is the corresponding oblique upper of sensing.This is because after burning mixture flows out spout, the cause that the pressure that on gas, is acted on has promptly disappeared, thereby weakened the lateral movement of gas sharp.
A cooker be positioned in this flame above the time, compare with the sort of natural shape of flame, the cooker that the shape of the flame of being controlled by existing side direction spout is existed has changed.This phenomenon is discussed in the U.S.'s 006 patent to some extent, and the flame burning that promptly is under the cooker bottom prolongs towards corresponding side 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 side direction.
It is thus clear that when the combustion gas in the burning mixture 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 understand the efficiency of heating surface that has influence on cooker negatively, particularly to those in daily life the most extensively and most probable the efficiency of heating surface of the cooker of diameter between 15 centimetres to 20 centimetres that be used.
Described first kind of shortcoming is; The flame top of part 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 be 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.Because the device with fixed dimension comprises all situations of the Peak Flow Rate of burning mixture in the time in fact can not looking after in the cooking.In fact this device size comprises the diameter of inner disc top end opening, is after the most probable situation of having considered when using this device in the cooking, to design according to qualifications.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, and those parts that contacted are all towards the excircle of cooker bottom surface.This has just caused by the center of cooker bottom surface outward extending large-area " cold temperature area ", thereby 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 have the cause that the flame top of maximum temperature can not directly touch the cooker bottom surface.It is thus clear that the cooling phenomenon of this kind flame must be negative for the high efficiency of heating surface that when cooking, will obtain.
What it must be understood that is, according to the explanation of above-mentioned first kind of shortcoming to loss heat energy, except the factor of the horizontal sensing of burner nozzle, the oversized dimensions factor of (outward) flame combustion circle (pyrosphere) in addition also can cause the heat-energy losses when cooking.Even when the burning ring of those oversized dimensions had spout upwards, this heat-energy losses also will inevitably take place.In above conclusion, the oversized dimensions of pyrosphere be meant with the radial dimension of apparatus of the present invention with those the most extensively and most probable to be used the radial dimension of cooker inconsistent.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 combustion circles.Wherein have one to be in large-sized outer burning ring that central undersized interior pyrosphere and is in the periphery.Yet the size of outer burning ring is all very big usually, and wherein maximum diameter can reach 12.5 centimetres.Use the sort of outer burning ring when the cooking, must cause the loss of heat energy.
Be the efficiency of heating surface of further improving when the cooking like this, must be conceived to have (outward) pyrosphere of the burner of new gas spout passage and optimum size.The device that it can be used to combine the flame heat regulating controlled invented to transmit, thus optimization ground adapt to those have the most extensively and most probable be used the cooker of size.
For this reason, to two kinds of above-mentioned shortcomings; Patent Application No. 12/313; 940 (940 patent applications) disclose the pyrosphere with new gas spout passage and preferred diameter; It also combines with the device of controlled heating capacity transmission, breathe out as its divide ground adapt to those have the most extensively and most probable be used the cooker of size.This spout passage has the structure with respect to the angle that raises up on outer flame circle plane of living in, so can guide burning mixture flowing along this angle direction that raises up.Thereby guaranteed in the stability of the flame kernel of spout channel exit, promptly to prevent that flame kernel breaks away from burning ring and flame kernel centers on the phenomenon that the spout channel outlet is jumped repeatedly.
Obviously; Compare with the passive technical scheme that device provided of the flame heat regulating the controlled transmission of disclosed the sort of detachable in 006 patent; Burner nozzle is comprised its structural modification pointed to and the optimum size of confirming outer flame circle, is a kind of technical scheme of active for improving flame heat efficient.Such 940 patent applications just propose a technical scheme preferably that when the cooking, improves flame heat efficient after combining these two kinds of schemes.
940 patent applications also disclose the ceramic material of selecting to have big thermal capacity and have made the device that can control the flame heat regulating transmission, also are a kind of effective factors for the thermal efficiency that improves when cooking.
But 940 patent applications fail to disclose the primary structure of a complete combustion furnace, comprise and two structures that subject under discussion is relevant energy-conservation and attractive in appearance.First relates to the substructure of burner, because of it helps in the cooking, to practice thrift combustion gas.Second relates to the structure that gas furnace has top panel, because of its device that can be used to cover the controlled heating capacity transmission of upwards settling makes gas furnace that smooth furnace roof face arranged.The gas furnace with smooth furnace roof face like this can incorporate a modern kitchen that requires utensil that effect attractive in appearance and excellent function are arranged.This means that if do not cover this device gas furnace does not just have significant market value.This is because the vertical visual effect of this device is not consistent with the plane visual effect at the top of settling the gas furnace sales counter, and does not possess the effect of beautifying the kitchen.
Must see that two above-mentioned subjects under discussion have same importance for a gas furnace with market value, because it is be equipped with the main place that the kitchen of gas furnace is a house, closely bound up with the main activities of one family.
House gas boiler is the utensil that people widely use.The carbon dioxide of enormous quantity has also been made in the combustion gas of using gas furnace to expend enormous quantity simultaneously, and it is the part in the carbon dioxide with greenhouse effects of whole human society manufacturing.Therefore, current society not only can be energy-conservation to invention and also the new kind of gas burners that helps kitchen attractive in appearance tangible demand is arranged.Use this new kind of gas burners can be so that the public can reduce expenditure and strengthens enjoying modern life style and enjoyment to the protection of environment with from the aspect of the aesthetic measure that promotes a modern kitchen from practicing thrift combustion gas.

The specific embodiment
Though concrete enforcement of the present invention can be in following narration after with reference to accompanying drawing, must be clear and definite be that the few in the many kinds of concrete manifestations of the spiritual and purpose of the present invention is only represented in these practical implementations.Numerous distortion and improvement to this practical implementation are conspicuous for the people who has at same ken.These distortion and improvement all are related with the present invention, thereby these distortion and improvement all are confirmed to be among the expressed spiritual purpose of the claim that is included in application of the present invention and the imagination.
Three parts that openly comprised of the present invention.First relates to the device that can control the flame heat regulating transmission that is produced by conventional burners.This burner has the gas spout of side direction.Second portion relates to the burner of (outward) pyrosphere with new gas spout passage and suitable dimension, and it combines with above-mentioned device.Disclosing with 940 patent applications of first and second part is identical.Third part relates to the primary structure of a complete gas furnace.The innovation burner of this stove has the gas mixer of air mixture and air, disperses the gas distributor of combustion gas and novel gas spout passage.Burner is centered on by the device of above-mentioned controlled heating capacity transmission and reaches focusing heat energy in the effect of cooker.And the top panel of gas furnace has been covered this device, thereby makes gas furnace that the visual effect attractive in appearance of smooth furnace roof face arranged.
First: be used to control the detachable device that flame heat regulating transmits.
From the boiler face structure of Fig. 1 with the existing gas burner shown in Figure 2 of United States Patent (USP) numbering 6,505,621 of United States Patent (USP) numbering 5,323,759, can see the device of its flame heat regulating controlled that lacks detachable transmission.This device can be placed on the superstructure that also centers on a burner on the boiler face increases the efficiency of heating surface of flame to cooker, has again to support cooker and the effect that prevents the heating of cooker handle.
The transmission of well-known flame heat regulating is to carry out through two approach of radiation and convection current.So under the effect of controlled heating capacity transfer device of the present invention, the control that the radiation of heat and the form of convection current can improve, thereby can implement effectively heating to cooker.The present invention just can reach and promote the purpose of flame to the efficiency of heating surface of cooker like this.
Fig. 1,2 and 3 have introduced the device 100 that the flame heat regulating controlled according to the detachable of first embodiment of the present invention transmits.This device by the inner disc 102 that is placed in the annular curved surface hollow on the boiler face 166 and one tetragonal peripheral 130 form.Inner disc 102 is positioned to the superstructure 178 around a burner, and itself is centered on by this periphery 130.Simultaneously peripheral 130 support again one have a bottom surface 174 cooker 168, this cooker 168 is to be placed on the burner.
As shown in Figure 2, inner disc 102 is thin wall circular walls to the oblique upper stretching, extension of a hollow, and an outer surface 106 is arranged, and inner surface 108, the edge of the annular that top end opening forms are that the edge of the top margin 110 and the annular of bottom end opening formation is base 112.Inner disc from the base 112 upwards and extend outwardly into top margin 110, so the size of top margin 110 greater than the size on base 112, they have same centre rotational axis 114 simultaneously.When along 108 the direction from rotating shaft 114 to inner surface, inner disc 102 has the inner surface 108 of the recessed song of an annular.Certainly optimal scheme is that the inner surface of this recessed song is a parabola corresponding to centre rotational axis 114.
Should be clear and definite be that the inner disc of inner surface of parabolic of inner surface or annular with recessed song of this annular is to design according to the heat radiation of the object of the invention control flame and the form of thermal convection current especially.
The inner disc 102 of this shape can deviate from radiations heat energy 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 photothermal 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 like this part being arranged, and this just means that the radiant heat of this part directly is not used for heating cooker.After the inner disc 102 that is mounted with annular curved surface hollow of the present invention; Can be reflected back heating cooker downwards and to extraradial heat; 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.
As shown in Figure 2 again, inner disc 102 has again and has been divided into two groups, numerous holes 116 that run through inner disc.Hole in first group is to be evenly distributed on the circumference 118 of a higher position of inner disc, and the top margin 110 of inner disc is approached in the position of this circumference.Hole in second group is to be evenly distributed on the circumference 120 of a lower position of inner disc, and the base 112 of inner disc is approached in the position of this circumference.But as scheme saidly, hole 116 has different distribution densities at two circumference 118 of inner disc on 120.
This uneven hole distributes and can be described by different distances A between two adjacent holes and B in the drawings.Distance A is the distance between two adjacent holes on the lower position circumference 120, is the distance between adjacent two holes on the higher position circumference 118 apart from B, and distance A obviously is less than apart from B.So another architectural feature of inner disc of the present invention is, than hole denser distribution is arranged at higher position at the hole of this inner disc lower position.Its essence is that the gross area at the hole of lower position is greater than the gross area at the hole at higher position.Should be clear and definite, the characteristic that this inhomogeneous hole distributes is the present invention's special setting for the convection current of controlling flame heat regulating.And the convection current of flame heat regulating is the convection current that has relied on air.Can know that the convection current of this air occurs in the space around the flame 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 lower temperature, and its surrounding space from flame flows to flame via the spatial channel that occupies lower position and 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 disc more densely distributed hole at position down that is arranged on of the present invention like this is to being used as mobile the provide less resistance of surrounding air auxiliary air, that lower temperature is arranged to the superstructure 178 of burner.Auxiliary air is vital for burning, is absolutely necessary the flame because wherein contained oxygen forms the burning of burning mixture.Can know that this burning mixture is formed by the mixing of the combustion gas of primary air and supply in burner.
Fig. 2 narrated tetragonal peripheral 130 is made up of four identical upwards 132 of plates of height " H2 " that settle, that top margin is arranged.Every plate has horizontal top margin 138 and base 140, outer surface 134 and inner surface 136.Four plates connect successively and are formed with tetragonal top margin, the periphery 130 of base and central symmetry axis 142.There is numerous hole 144 to be evenly distributed on the every plate in addition.According to one of the object of the invention comprise can control air the form of convection current, the number that can know the hole 144 that has run through peripheral is more than the hole that has run through inner disc 116.Its essence is that the gross area of placing hole outside is greater than the gross area of hole on inner disc.
By Fig. 2, the every plate of upwards settling has one to extend upward structure 146 on top margin 138 position intermediate again.This structure also has first and second sides 148 that make progress and 150 compositions of equal height " H3 " by top margin 152.As scheme saidly, the height of dual-side " H3 " is the height " H2 " that is lower than the top margin of every plate.The top margin 152 that extends upward structure in addition is longer than the length of side of dual- side 148 and 150, extends upward the function that structure 146 has 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 not this structure, this hot-fluid that outwards flows can change the hot-fluid that upwards flows into.The hot-fluid that should upwards flow like this can be placed on the flame one, and the object that intersects with this hot-fluid that upwards flows orientation and the parts of object heat.Of Fig. 3, cooker 168 is to be placed on peripheral extending upward on the structure 146, and the handle 170 of cooker is to be on the same vertical plane with the center of structure top margin 152 and the symmetry axis 142 of periphery.Extend upward structure 146 like this and can prevent that cooker handle 170 from receiving unnecessary heating.
By shown in Figure 3, except this function, this structure 146 that extends upward is the cookers that are designed to be supported with planar base surface 174 by the present invention, perhaps has the cooker like frying pan and so on of convex bottom face.
Again by Fig. 2, have on the inner surface 136 of every plate first group be on and position fixing down with structure 162 and 164.Than upper part fixing be with structure 162 near and be lower than on the position of horizontal top margin 138 of plate, and be near on the position on the horizontal base 140 of upper sheet space with structure 164 at position down fixing.These two fixing are alignd with upwardly extending first side 148 with structure simultaneously.Same also have on inner surface 136 second group fixing 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 also align with upwardly extending second side 150.
Can know above-mentioned fixing with structure, for example semicircular annulus is that the cooker that adds that is used for placing outside fixing identical first and second detachables supports 154 and 156.Like this, undersized cooker can be placed in additional cooker and supports when the cooking.
Of Fig. 2, first additional cooker support 154 has the shape of the letter " U " of image inversion, is made up of with the identical first and second downward structure 154b and 154c a horizontal top 154a.This cooker supports 154 and can be made by metal flat bar or pole.
When using cooker to support 154; The first downward structure 154b is inserted in first group of first plate 132 fixing with among structure 162 and 164, and the second downward structure 1554c is inserted in second group of second plate 132 fixing with among structure 163 and 165.As scheme saidly, and second plate is being close to first plate 132 in the direction of the clock down, and this clockwise direction is the symmetry axis 142 according to the periphery, and first and second plates are formed with the connection of an angle of 90 degrees again.Under above-mentioned connection, the projection that two top margins 138 of the top 154a that first cooker supports and first and second adjacent plates make progress forms a right angle triangle, and this top 154a is the hypotenuse of right angled triangle.
Identically, second cooker can be installed and support 156.By shown in Figure 1, this just causes top 154a that first and second cookers support and 156a to parallel and narrower interval is arranged.This moment, undersized pan can be placed on this two parallel top 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, the cooker that can select to add is supported with the shape of various deformation.But the variation according to the present invention spirit and purpose, this form is hard-core.In fact, it all is suitable that the cooker of any form supports, as long as it is detachable, is to be installed in tetragonal outer placing with structure by application of fixed again.
Fixing in addition with structure 162,164,163 and 165 can be positioned on the outer surface 134 of every plate.Also have according to spirit of the present invention and purpose, on every identical plate 132, can have at least one fixedly to use structure.
Fig. 3 has explained the device of the flame heat regulating the controlled transmission of using first kind of embodiment of the present invention.The boiler face 166 that the inner disc 102 of annular curved surface hollow at first is positioned in gas furnace gets on around the superstructure that includes dome 178 of a burner.Tetragonal peripheral 130 are positioned in boiler face 166 again gets on around this inner disc.Such arrangement makes the rotating shaft 114 of inner disc overlap with peripheral symmetry axis 142, and has aimed at the center of superstructure dome 180.On the ringwall of dome 180, have along the gas spout 182 of numerous side direction of circle distribution.In addition, one have the cooker 168 of cylindrical outer surface 176 bottom surface 174 be to be placed on peripheral each to extend upward on the top margin 152 of structure.Under such arrangement, the position of inner disc top margin 110 is the positions that are higher than the superstructure dome 180 of burner, and peripheral quadrangle top margin promptly be the top margin 138 of plate be placed at least with the equally high position of the top margin 110 of inner disc.
By extending upward the gap 172 between the bottom surface 174 of tetragonal top margin 138 and cooker that structure 146 caused enough width are arranged in addition.This gap 172 allows outwards not flowed out to blocked by the waste gas of the heat of flame combustion generation and air, and continues to make progress mobile along the outer surface 176 of cooker.So just can come heating cooker 168 through the heating outer surface.Can imagine that owing to exist enough wide gap 172 just can not produce an outside pressure with regard to the hot gas, this outside pressure can make flame spray gap 172 and cause the burning of flame outside the gap.As at that rate, the flame outside the periphery can not farthest be used for to the heating of cooker 168.Therefore, the structure 146 that extends upward that is with enough height outward is crucial for the efficiency of heating surface that improves when the cooking.
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.Burning at burning mixture in the core of flame is to take place under the participation at oxygen.According to the description to the frame for movement of burner that is seen everywhere, the core of flame is the spout that is connecting burner, because flowed out the burning mixture that pressure is arranged there in addition.And for example in aforesaid air flowed, the surrounding air with lower temperature had bigger proportion, and it through 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 embodiment of the device of flame heat regulating transmission and follow these well-known flames theories just, obtains the high efficiency of heating surface when cooking through the radiation of control flame heat regulating and the form of convection current.
For this reason, Fig. 3 has also set forth the convection of heat of being controlled by inner disc 102 and has comprised cross-ventilated form.Auxiliary air 190 with minimum temperature around the burner 198 flow to flame 184 bottom 188 go to get involved flame burning.This auxiliary air 190 is at first through peripheral hole 144, and then mainly through be distributed in inner disc down the position near the hole 116 of the dense distribution on base 112.
Part gets into the air of inner disc and has participated in the burning of the burning mixture 183 of ejection from the burner top and formed flame 184; The burning that produces flame waste gas is the top 186 of continuously carrying out until flame, and the top of flame is to be under the bottom surface 174 of cooker.A part gets into the air 190 of inner disc and does not get involved burning, continues then upwards to flow but be heated, and becomes the hot-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 top 186 of hot-air 196 and flame.Hot-air 196 outwards flows out through gap 172 from the top 186 of flame with the waste gas 189 that flame combustion produces then, and is upwards mobile and away from flame 184 along the cylindrical outer surface of cooker 176.It also continues heating cooker 168 through the outer surface of heating cooker simultaneously.When the cooking, can reach the cooker efficient heating like this through the form of control convection of heat.And in this controlled convection of heat, the flowing of hot-air 196 and waste gas, carry out with outer surface 176 bottom surface 174 that all is centered around cooker.
When estimating above-mentioned flame convection of heat to the contribution of high efficiency heating, inner disc 102 of the present invention has greatly been controlled the flame convection of heat and has been comprised cross-ventilated form.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 burning of burning mixture, and also helps to reach the completing combustion of burning mixture because of it.It two is that the hot-air 196 that burning produces is surrounded thereby is forced to flow upward by inner disc 102 with waste gas 189.They are at first to 174 heating of the bottom surface of cooker, flow out through gap 172 then and continuously to outer surface 176 heating of cooker.
The form of this controlled convection of heat is extremely important for the high efficiency of heating surface that when cooking, will obtain, and particularly between the bottom surface 174 of burner dome 180 and cooker, has only under the situation of very limited spatial altitude.The burning mixture that pressure and high flow rate are arranged 183 that from the spout of burner, sprays at once with auxiliary air in oxygen combine and burn.The flame waste gas that burning produces 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, natural kenel normal, foregoing thermal convection current can be destroyed and cause 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 inner disc of the present invention like this on the boiler face, will cause the low efficiency of heating surface, and become sharp contrast with the high efficiency of heating surface that the present invention is obtained to cooker.
What can also confirm in addition is, except the form of above-mentioned convection of heat by inner disc 102 controls, also the high efficiency of heating surface has been played important contribution by peripheral 130 gaps that enough width are arranged 172 that provide.Because of it has facilitated the form of the controlled convection of heat that is obtained.
Except the form of control convection of heat, inner disc 102 of the present invention also can be controlled the thermal-radiating form of narrating as preceding.The radiation of heat of this control has also been played effect to the efficient heating in the cooking.
Well-known heat radiation is to have the surrounding environment of lower temperature from an object sensing with higher temperature.So the outer surface 106 of heated inner disc is always outwards launched radiant heat in the cooking.But owing to exist tetragonal peripheral 130 and centered on inner disc 102, thus the radiant heat that outwards sends by the outer surface 106 of inner disc by peripheral 130 stop.Peripheral like this 130 just help to maintain the high temperature in the peripheral region of superstructure 178 of burner as an insulated wall, yet should all be under the bottom surface 174 of cooker in the zone, and tetragonal so peripheral 130 pairs of high efficiencies of heating surface have additional contribution.
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 is set forth in instance of the present disclosure (I) part.
In addition, can see that from the structure of above disclosed first embodiment it can have multiple structural change, can be added in the top margin 110 of inner disc and the mechanical strength that inner disc 102 is strengthened on base 112 such as a crimping or frame.
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, this inner disc 102 can be polygonal, such as the quadrangle of symmetry, pentagon, hexagon etc.Same reason, peripheral 130 also can be the polygonal of any symmetry.
Fig. 5 has explained orally the distortion 132 ' of the plate of upwards settling 132.Than above-mentioned plate 132, this distortion has at least one downward pillar 139, and it is positioned on the base 140 ' of every plate 132 '.This pillar 139 is used to support this plate, thereby supports entire 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.
Device that flame heat regulating the transmits 100 included inner disc 102 and peripheral 130 the most handy durable metal or metal alloys controlled of the present invention comprises that iron and steel make.In addition, can do suitable surface treatment, comprise face coat inside and outside surperficial 108 and 106 of inner disc.Surface treatment helps the control to the form of heat radiation and thermal convection current, and the durability that increases this device.Surface treatment can with comprise the chemistry, electrochemical, or the pottery method.The color on the surface of handling is black or white preferably.Likewise, peripheral inside and outside surface promptly is that inside and outside surperficial 136 of plate also can be cooked identical above-mentioned surface treatment with 134.
Fig. 4 has described second embodiment 200 of the present invention, it comprised an annular curved surface hollow inner disc 202 and a hollow columniform peripheral 230: promptly be the columniform ringwall that makes progress.
Can confirm that inner disc 202 is with inner disc 102 striking resemblances in first embodiment, so each structure of inner disc 202 can not narrated again.The structure of inner disc 202 in Fig. 4 by there being three-figure numeral to represent.A structure for inner disc 202 is same as the same structure in inner disc 102 because of it, digital identical with in inner disc 102 of first and second numeral in the middle of the numeral of this structure of mark.Different is that tertiary numeral is replaced with 200, rather than in inner disc 102 100.
As scheme said; Columniform peripheral 230 have the height of a top margin to be " H12 "; And an outside cylinder 234 is arranged is outer surface, and inboard cylinder 236 is an inner surface, the top margin 238 of the annular that the top circular open forms; The base 240 of the annular that the bottom circular open forms, and a peripheral rotating shaft 242.When combination inner disc and periphery, this rotating shaft 242 overlaps consistent with the rotating shaft 214 of inner disc.Moreover numerous holes 244 distributes equably and has penetrated the periphery.According to spirit of the present invention and purpose, the number of hole is the number more than hole on inner disc 202 on peripheral 230.
On the top margin 238 of periphery, there are at least three identical circumference to comprise the equally distributed structure 246 that extends upward of top margin by the periphery.This structure 246 has horizontal top margin 252 and first and second sides 248 and 250 that make progress with equal height " H13 ".Certainly the height " H13 " of this side is the height " H12 " that is designed to be lower than peripheral top margin.In addition, the length that extends upward the horizontal top margin 252 of structure is longer than the length of dual-side 248 and 250.

The result of test successively who has been listed by table one proved than the needed time of burner of using the commercial combustion gas stove, used device of the present invention back the heating of cooker that less and larger volume are arranged 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 practicing thrift combustion gas, the heat radiation of control flame and the form of thermal convection current are vital.The result of test has also proved simultaneously, has used the device of controlling the flame heat regulating transmission of the present invention greatly to reduce combustion gas that when the cooking, is consumed and the carbon dioxide that greenhouse effects are arranged that is produced.
Above-mentioned open in, the argumentation of first and second embodiments of the present invention is to be directed against the gas furnace that boiler face is equipped with the burner of closed installing structure.Yet the confirmable the present invention of being also is suitable for the gas furnace that boiler face is equipped with the burner of open-type installing structure.
In addition, according to spirit of the present invention and purpose, above-mentioned periphery 130 or 230 can be the structure of a prolongation, can be used to around two burners that are arranged side by side.
According to spirit of the present invention and purpose, inner disc 102 or 202 and pairing peripheral 130 or 230 can be made into incorporate structure again.For the structure of incorporate inner disc 102 and periphery 130, the top margin 110 of the annular of inner disc is connected with the every plate 132 of periphery simultaneously.Its junction comprises that 137 is of Fig. 2, is on every plate inner surface 136, and 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.The rotating shaft 114 of incorporate inner disc coincides with peripheral symmetry axis 142, and inner disc 102 can both stand on the boiler face with peripheral 130 separately like this.
For the incorporate structure of second embodiment, the top margin 210 of the annular of inner disc 202 comprises it being to be connected on the circumference than the upper part that is in peripheral 230 inner surfaces 236.This circumference is parallel to the top margin 238 of peripheral annular, and the rotating shaft 214 of inner disc coincides with peripheral rotating shaft 242 like this.In addition, incorporate model can have more change structurally.
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 tetragonal peripheral 130 or hollow columniform peripheral 230.They are according to all uniformly-spaced being connected with the inner disc of annular, and every fillet has the horizontal top margin 152 of equal length.In addition, every fillet has with the same maximum height of plate 132, and its bottom is to be supported on the boiler face simultaneously.The top margin of at least three fillets can be used for supporting a cooker like this, and prevents the heating to the cooker handle.
Will also be appreciated that in addition the device of controlling the flame heat regulating transmission of the present invention only includes the inner disc of annular curved surface hollow.Under this structure, this inner disc is placed on the superstructure that centers on a flame burner of gas furnace on the boiler face, and existing commercialization fence is used to support cooker.
As for selection is made this device with which type of material, 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 property.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 by fibre-reinforced ceramic composite greatly, and this composite has been used fibre-reinforced manufacturing process and processed.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 with ceramic material have positive effect.This to the present invention the high efficiency of heating surface in when cooking that will obtain also have superiority.
Second portion: burner with (outward) flame combustion circle of new gas spout passage and suitable dimension.
Be appreciated that above disclosed device is to have combined existing burner with fuel gas of sideward directed spout.The architectural feature of this kind spout is narrated in " narration prior art " of the present disclosure joint.Two kinds of main shortcomings of this spout have also been narrated in addition and for the negative effect that the high efficiency of heating surface had that will obtain, the phenomenon of the most extreme flame extending transversely when having maximum stream flow (pressure) comprising special combustion gas in burning mixture.
Like this; For the high efficiency of heating surface that when being used the cooker of size, will obtain with using the most extensive and most probable; Particularly again application have maximum stream flow the flame that combustion gas produced the time, a kind of suitable countermeasure of the present invention be exactly let flame along one with respect to horizontal angle direction go the burning.In this state, the flame burning direction is the direction from the gas spout of correspondence to the bottom surface of cooker, 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. 6 has shown the superstructure 300 of burner of the present invention, and it has numerous novel gas spout passages 314.This superstructure 300 that is placed on the gas furnace furnace table surface is made up of 340 of the hollow stem that makes progress that the dome 302 and at a dismountable top is fixed on the furnace table surface 166.And the arrangement of dome 302 is the necks 340 of this hollow that coincide to getting off.
Dome has a horizontal circular top 304 to connect a downward cylindrical shape ringwall 306, thereby has at the inner interior concave space 330 under shed of dome.This ringwall has outside anchor ring 308, interior side ring surface 310 and horizontal end anchor ring 312.In addition, also has numerous vertical slots 314 under shed.Vertical slot radially arranges and has cut the part ringwall 306 that comprises anchor ring 312 at the bottom of the dome with the compartment of terrain by the circumference of dome ringwall.Hollow stem 340 is the cylindrical shape ringwalls 342 that contain a central gas channel 344 and tip circle anchor ring 346, and this central gas channel is used for through the mist 360 of combustion gas with pressure and primary air.Therefore, the central gas channel 344 of neck can be connected with the interior concave space 330 of dome the tip circle anchor ring 346 of hollow stem matches with the end anchor ring 312 of dome 302.
Shown in Fig. 6 and Fig. 6 A, this novel jet 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.Outwards opening 326 and are outside anchor rings 308 of being placed in cylindrical ringwall respectively to inner opening 332 with interior side ring surface 310 on.Less space 314b has the symmetry axis 332 of a side direction, also 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.
The space 314a of expansion also have one be represented as the top the transversely arranged downward bottom opening 318 and identical downward two sides of the inner surface that points to oblique upper 316.Like this, be reference with the symmetry axis 322 in less space, this has an angle " D " to top inner surface 316 that oblique upper points to.In an embodiment preferred, this angle " D " is 45 degree.Downward in addition two sides have shown in Fig. 6 A, than the shape of the right-angled trapezium of the vertical cross section of large space 314a.
Continuation is by shown in Fig. 6 and Fig. 6 A, is in the outside anchor ring 308 that high-end side 316a has connected ringwall 306 than one of the inner surface 316 of large space.Another side 316b at 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, than the bottom end opening that has formed vertical slot 314 under shed 320 that has laterally connected less space under shed 318 of large space, it has radially cut the end anchor ring 312 of dome.
Like this; When the dome 302 at top be positioned to match with hollow stem 340 after; Those vertical slots just are converted into corresponding novel body gas blowout mouth passage 314 of the present invention, and wherein the outside opening of vertical slot is exactly the gas vent 326 of passage, and vertical slot is exactly the gas access 322 of passage to inner opening.
Visible by Fig. 6; Enter into an internal cavity of the burner superstructure of mainly forming when the burning mixture with pressure 360 after by the interior concave space 330 of dome 302; Gas 360 has at first passed through the less space 314b of novel jet nozzle 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 combustion gas in the burning mixture 360 of the central gas channel that gets into neck has the selected pressure (or flow velocity) of gas furnace 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.Dominating down of this structure, can form mist and in than large space 314a, have steady flow than jogging speed.On gas vent 326 positions of this mist, just formed stable flame kernel when lighting like this by an electronic ignition device (not having to show) at the novel jet nozzle passage.
In addition, passed through to control the hole of flame heat regulating transfer device from the auxiliary air of flame surrounding space and participated in flame burning, 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.
What it must be understood that is again, the preferred angle of 45 degree that the burning meeting of flame kernel is had along the inner surface 316 of novel jet nozzle passage 314, and 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.
Instance (II)
Following discloses be that the present invention is used in the instance on the gas range 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 instance is provided, rather than for restriction of the present invention.Yet in order to reduce length, the following open result who only narrates instance.Details relevant for instance can be checked Patent Application No. 12/313,940.
Table two: to the result of experiment sample (I-Cap) and check sample (C-Cap) test
Test Sample Cooker Time (branch) Time difference (branch) The % of check sample Increase efficient %
1 C?Cap Teapot 10.38 ? ? ?
2 C-Cap Teapot 10.50 ? ? ?
3 I-Cap Teapot 9.38 -1.14 89.09 10.91
The experimental result of in table two, enumerating proves, uses the burner with novel jet nozzle passage of the present invention 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.
Be appreciated that, have the inner surface 316 that points to oblique upper expansion not only slowed down the flow velocity of burning mixture than large space 314a, but also 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 through 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.Having under the purpose of flows at angles in order to obtain burning mixture, discussion is different from above-mentioned disclosed all schemes to get off.
Fig. 6 B discloses and has been different from another kind of embodiment 314 ' the spout passage 314 shown in Fig. 6 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 dome ringwall 306.The inner bottom surface 318 ' of extending space 314 ' a has an angle " E " with respect to the end anchor ring of top cover so more gradually, and the inner surface 316 ' that points to oblique upper in this space has an angle " F ".Visible by 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 vent 326 ' in the space of this bigger expansion must be greater than the gas access 322 ' in this less space, and angle " F " is always greater than angle " E ", and using this structure is to comprise in order to form stable flame kernel.
Also have by shown in Fig. 6 C another novel jet nozzle passage 314 " be the horizontal top 304 that radially is distributed in dome 302 up with by a circumference of dome with the compartment of terrain.Have upwards symmetry axis 332 " novel jet nozzle passage 314 " by a less space 314 " b connected the space 314 of a bigger expansion " a.The less space of using as air inlet 314 " b and symmetry axis 32 " the direction orientation consistent, it is with respect to one 90 angles spent are laterally arranged.And the gas access 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 vents 326 at the dome top " and two inner surfaces 316 that stretch to oblique upper ".
To the structure type shown in Fig. 6 C, be appreciated that novel jet nozzle passage of the present invention also can have circular architectural feature from Fig. 6 A.Specifically, the spout passage 314 shown in Fig. 6 C " contain one inverted symmetrical truncated cone shape arranged extending space 314 " a coaxial be connected one downwards the cylindrical less space of using as air inlet 314 arranged " b.And the spout passage 314 that in Fig. 6 A, is shown can be by above-mentioned passage 314 " structure half the and oriented under shed replace.As for concerning at the spout passage 314 ' shown in Fig. 6 B, this bigger extending space 314 ' a can be that an asymmetrical inverted frustum of a cone has connected less columniform space a 314 ' b.
To Fig. 6 C, the less space that the invention also discloses the novel jet nozzle passage changes the architectural feature of its sensing from Fig. 6 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 dome to the top of dome.
From an optimized technical scheme, the position of spout passage can reduce three types: (1) is if the angle in this less space " G " is that the spout passage can be disposed on the ringwall 306 of dome between zero degree to four 15 degree; (2) if this angle " G " is 45 when spending, passage can dispose at the dome top 304 with the intersection of dome ringwall 306; (3) if this angle is to spend when 90 spend greater than 45, passage can be disposed the top 304 at dome.Yet as aforesaid, according to spirit of the present invention and purpose; No matter how this scheme to change the orientation angle in less space and the position of spout passage, this includes one must be greater than the gas access in this less space to the gas vent of the bigger extending space of oblique upper sensing inner surface.
Other structural change is also arranged in addition.Visible by Fig. 6 A; Except being connected the structure of less space 314b by this bigger extending space 314a, this novel jet nozzle passage is the space of this expansion, promptly this is connected to the interior side ring surface 310 of ringwall to other end 316b of the inner surface of oblique upper sensing extension.Like this, this passage is that the space of an expansion includes a bigger gas vent, the inner surface that a less gas access and is pointed to oblique upper.
Moreover, except it is disposed the selection on the dome 302, also can this novel jet nozzle passage be disposed and on the ringwall 342 of hollow stem, obtain identical effect.Also have, this novel jet nozzle passage can be disposed simultaneously on dome 302 and neck 340.In the sort of structure, the spout passage has cut the end anchor ring 312 of dome and the tip circle anchor ring 346 of neck simultaneously.Yet it is understandable that, the details of these alternative structures, be conspicuous for the people of the level that in the gas furnace manufacturing industry, possesses skills, so the present invention no longer does the description of repetition to it.
Fig. 6 D discloses the malformation of relevant dome 302.The horizontal projecting edge 344 of one annular is to be on the outside anchor ring 308 of dome ringwall 306, and aligns with the top at dome top 304.The bottom surface 348 of this projecting edge is an anchor ring, and it is consistent to the sensing of the inner surface 316 that points to oblique upper with all spout passages 314.Like this when flame along this oblique upper during to the angle burning pointed to, just can not change angle because of receiving the influence that this projecting edge exists.In addition, an annular groove or a cavity 346 under shed is to dispose in the junction of this projecting edge 344 with the dome ringwall.
This projecting edge 344 be design be used for preventing in the cooking because of have soup juice splash down the phenomenon of the knock down the flame that possibly cause.This annular groove 346 under shed is to be used for stablizing faint flare.The combustion gas of this flare during by the selected minimum flow velocity of gas furnace user (or pressure) forms.
Can see,, also can combine simultaneously by the distortion of the disclosed dome structure of Fig. 6 D and to form a kind of new dome structure with distortion by the spout passage shown in Fig. 6 B according to spirit of the present invention and purpose.
Yet; Still according to first kind of reason that possibly cause thermal loss in aforementioned chapters and sections " prior art background ", analyzing; Can reasoning to a burner (outside) when the flame combustion circle has oversize, even be when upwards disposing at the spout of this pyrosphere, also can cause the loss of heat.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 top margin of the annular of inner disc 102 or 202.The device that has the flame heat regulating the controlled 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 of inner disc top margin 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 the dimensional uniformity of inner disc top and cooker coordinated.
Instance (III)
Following discloses be that the present invention is used in the instance 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 instance is provided, rather than for restriction of the present invention.Yet in order to reduce length, the following open result who only narrates instance.Details relevant for instance can be checked Patent Application No. 12/313,940.
Table three: to the result of experiment sample (reality) and check sample (contrast) test
Test Sample Cooker Time (branch) Time difference (branch) The % of check sample The efficient % that increases
1 Contrast Pot 6.17 ? ? ?
2 Real one Pot 5.93 -0.24 96.1 3.9
3 Real two Pot 4.77 -1.40 77.3 22.7
4 Real three Pot 5.02 -1.15 81.4 18.6
The experimental result of giving an example in the table three shows, in experiment sample real three, has used the annular top cover with spout passage of the present invention, and it is percent 18.6 that the previous status of commodity burner (being check sample) has produced significant thermal loss.According to the architectural feature of original commodity top cover, can analyze, first reason that causes thermal loss 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 gas spout.
We can say that perhaps the contrast test of being formed from check sample and experiment sample real three has shown that suitable pyrosphere size and novel gas spout passage are very necessary for the efficiency of heating surface that improves flame.This novel gas spout passage comprises that the less space with a less gas access has connected and has one than atmospheric outlet and space one of the inner surface that points to oblique upper bigger expansion.This just makes burning mixture in this extending space, slow down its flow velocity gradually.Burning mixture with low flow velocity gas vent, again with the participation of auxiliary air under formed flame, than the formed flame of the top cover of existing goods outer burning ring, can have combustion reaction completely.And then make that formed flame can have higher flame temperature in the experiment sample real two and real three of the top cover of the annular that uses manufacturing of the present invention.Caused that like this obvious energy-saving effect is arranged when adding hot water.
If compare with the result of test experiments sample real three, test experiments sample real two shown have extra percent 4.1 energy-conservation.This is the contribution owing to the controlled heating capacity transfer device 200 of the present invention, because of it has controlled the form of heat radiation and thermal convection current.Meaningfully, than check sample, the test of experiment sample real has shown it almost is identical with percent 4.1 percent 3.9 energy-saving effect.And in the test of experiment sample real 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 real 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 instance (I); Energy-conservation largely (II) (greater than percent 14.6; With 10.9 percent) with in instance (III) by energy-conservation (percent 4) of the real two less degree compared with real three; Can be clear that, compare that the gas spout of sideward directed has caused extremely significant heat-energy losses with the burner new gas spout passage of the present invention that points to oblique upper with being directed upwards towards.
The experimental result of more than enumerating is consistent with theoretical supposition: promptly be exactly the efficiency of heating surface that new gas spout passage of the present invention has greatly strengthened flame in the cooking, because of it has controlled the form of flame, thereby prevented a large amount of heat-energy losses.In addition, device of the present invention has still been contributed the energy-conservation of part.Like this, result of experiment just proved, the burner that the novel jet nozzle passage is arranged that the present invention combines with controlled heating capacity transfer device is to a complete sum obtaining the best efficiency of heating surface when cooking technical scheme preferably.
In addition, what it must be understood that is 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, is used the size of cooker according to having the most extensively with most probable ground again, thereby obtains the efficiency of heating surface of the best when cooking.These group data comprise that the optimization diameter of top margin of the annular of inner disc is 19 centimeters, and the diameter of the pairing largest circumference of gas vent of all the spout passages on one (outward) pyrosphere is 8 centimeters.And a peak position of the numerical value of these the two kinds of diameters said gas vent 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 largest circumference that this diameter is 8 centimeters is according to result in instance (III) and reasoning.This circumference is along producing the upwards gas vent 326 of each novel jet nozzle passage of combustion flame at outer burning ring " center 322 " formed.Yet what it must be understood that is; 8 centimeters spout passages 314 that also are applicable to one (outward) pyrosphere of this maximum gauge just like the gas vent 326 described in Fig. 6 A, and these dispose the spout passage of burner superstructure controlled that flame had with respect to comprising of horizontal direction the angle of 45 degree.Condition when having maximum pressure (or flow velocity) according to 2.5 centimeters to 3 centimeters of above-mentioned optimization distances with burning mixture again, an annular that can expect generation is about 14 centimeters to the collar diameter of the wall with flues that oblique upper points to.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, can heat the cooker of this selected size efficiently.
Moreover, must be clear that the burning mixture of waiting until elevated pressures in the cooking, having is used by the most extensive and most probable ground.The diameter on the annular wall with flues top that is produced at that time can and can expection be obtained gratifying energy-saving effect less than 14 centimeters that estimate.This prediction is to have prevented additionally that according to the inner disc that in instance (I), provided the experimental result of the loss of heat energy from coming reasoning.
Also have to have for a short time during in combustion gas, also can expect satisfied energy-saving effect to middle pressure.Because this time, the device of controlled heating capacity transmission 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 cylindrical pot also has the architectural feature of spending at 90 of basal surface and lateral surface that is connected to compare, the outer surface of frying pan has bigger area and smooth continuous curve usually.Like this, after having used the present invention and the burner that new gas spout 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.

As the distortion that extends upward structure 146 by four of the periphery of Fig. 2 narration or by at least three distortion that extend upward structure 246 of the periphery of Fig. 4 narration, gas furnace of the present invention has been used a plurality of (more than three or three) cooker eyelid retractor 514 identical, that " T " shape shape is arranged.They comprise that by the circumference of periphery top margin is at a distance of distributing and can removably being connected on the outside anchor ring of periphery 506 through comprising the securing member such as screw and nut.Each identical eyelid retractor 514 has comprised that one has the vertical pillar 522 of bottom 524.When in the outer toroid connected in star 467 that pillar 522 and peripheral 506 is positioned in the burner dash receiver, the position on this pillar top is the top margin 510 a little more than the periphery.See again that the top of pillar has connected the horizontal platy structure 518 that makes progress, connected the horizontal platy structure 516 that tilts to oblique lower direction on the top of platy structure.The junction of such two platy structures has just formed a straight top margin 520 of this cooker eyelid retractor.Shown in Fig. 8 A and 9A, the width of the platy structure 518 that should make progress is the width much larger than this vertical pillar 522.This horizontal platy structure 518 can be used as the thermal resistance baffle plate like this, when the cooking, prevents that the handle of cooker from receiving unnecessary heating.
A plurality of cooker eyelid retractors of this dispersion also can be made into the structure of an integration.A plurality of eyelid retractors in this structure comprise that by the circumference of periphery top margin has connected one at top and the annulus in the horizontal arrangement of bottom simultaneously at a distance of distributing.Annulus on top is the place slightly down, top that is connected vertical pillar 522, the annulus of bottom be fixed on vertical pillar bottom slightly on locate.It is additionally to have strengthened the periphery that this kind has one of the advantage of the cooker eyelid retractor of integrated structure, comprises the mechanical strength of the periphery of particularly using ceramic material, this be because when its with peripheral being connected after make the periphery have the mechanism of enhancing structural behaviour.
In addition, upwards can being made into horizontal platy structure 518 and 516 to oblique below of cooker eyelid retractor has with peripheral 506 identical architectural features that comprise circular arc.Use cooker eyelid retractor of the present invention particularly in order to cooperate the periphery that is used as insulated wall that comprises with ceramic material.The cooker eyelid retractor made from metal or metal alloy that is somebody's turn to do " T " shape is an optimum structure of supporting cooker, and the top margin 520 that it is straight can be used for being supported with the cooker of planar base surface.And the platy structure 516 of its oblique inclination can be supported with the cooker that comprises the Chinese style frying pan of convex bottom face, also can be used for supporting the flat cooker of small size diameter.As the distortion of the horizontal platy structure 516 that tilts to oblique lower direction, it can be the radially fillet shape structure that tilts to oblique lower direction.As distortion further, the horizontal platy structure 518 that makes progress of cooker eyelid retractor also is a fillet shape structure upwards, and then the distortion that has formed eyelid retractor is that a vertical pillar has connected a radially fillet shape structure to oblique lower direction inclination.Likewise, the dispersion of these a plurality of distortion or the cooker eyelid retractor in the structure of integrating removably be connected with the periphery.In addition, according to spirit of the present invention and purpose, dismountable cooker that other adds supports: the support 256,258 and 260 such as in the narration of disclosure first also is applicable to above disclosed gas furnace.
Shown in Fig. 8 A and the 9A is how to settle inner disc 496, periphery 506 and cooker eyelid retractor 514.The peripheral base 512 and the bottom 524 of eyelid retractor are to be among the outer toroid connected in star 467, and have been prevented from their moving in groove.This is because the present invention can be designed with the structure that restriction is peripheral and the cooker eyelid retractor moves in groove.Inner disc 496 has surrounded the superstructure of burner, and this structure includes the annular top cover 530 at outer burning ring top and the gas receiver 574 at middle part, the top dome 554 of interior pyrosphere and the hollow cylinder 614 at middle part.In addition, inner disc is positioned in the medium pore 414 of gas furnace top panel after removably being combined with peripheral top margin 502 and 510 again, and aligns with the end face of this removable panel.Like this top panel 412 just visually covered peripheral 506 with inner disc 496, thereby make the present invention have the end face of a smooth gas furnace.The visual effect of this flat top surface is consistent with the flat top surface visual effect that the gas furnace sales counter is installed.
What in this case, have only the cooker eyelid retractor is to be on the plane of top panel with oblique two platy structures 518 and 516 upwards.Yet according to the structure in the optimization of 940 patent applications, this two platy structure just exceeds peripheral 1 centimeter, promptly also only exceeds 1 centimeter of the end face of panel 412.Like this, just can not have influence on the visual effect attractive in appearance on the plane of gas furnace of the present invention.Be appreciated that the advantage of this scheme is anyly to have that large diameter flat cooker can be placed on the top margin of this eyelid retractor and the drawback that can not cause the outlet of blocking the waste gas that produced by burning and hot-air.
As the second embodiment 400A of gas furnace of the present invention, the top margin 520 that Fig. 8 B and 9B disclose the cooker eyelid retractor of " T " shape is designed to align with the end face of top panel 412.When implementing this scheme, only need to increase many abutment walls 440,442,444 and 448 and the height of additional abutment wall 450, reach remodeling to the superstructure 434 of gas furnace.The advantage of this embodiment is, the top margin that comprises the cooker eyelid retractor is all covered by panel and reached the effect of plane visual completely of gas furnace.Its shortcoming is when using the flat cooker of super-large diameter size, because of the diameter of its bottom surface is equal to, or greater than the diameter of medium pore 414, so must remove top panel 412.Yet be appreciated that among the life style in modern times that the chance of using this oversize cooker is fewer, and it is also very convenient to remove top panel, so these two kinds of embodiments 400 all are that the present invention recommends with 400a.
The base 504 of inner disc 496 is positioned to and is higher than and aligns with the center circumferential of interior toroidal cavity 465.When in the cooking, overflowing if any soup like this, soup at first can be contained by inner disc 496 and receive and flow down along its inner surface, in being collected into then among the toroidal cavity.Gas furnace of the present invention so just can be from toroidal cavity in the easy cleaning and removable inner disc, and has the advantage of easy cleaning.Inner disc 496 can also have additional structural in addition, and it is removably combined with peripheral 506.For example inner disc has the frame of outwards routing up on top margin 502, and this frame can be hung on the peripheral top margin 510, and inner disc is integrated with peripheral.And for example, can use some dismountable securing members and pass the purpose that reaches integration near the place of peripheral and inner disc top margin 510 and 502.
Be appreciated that according to disclosed second embodiment of having only inner disc in first, gas furnace of the present invention also can be used the scheme that this device has only inner disc 496.This moment, this inner disc was again removably to be connected with the cooker eyelid retractor of the cooker eyelid retractor that comprises distortion above-mentioned a plurality of dispersions or in the structure of integrating, hung over such as the frame that turns up with the inner disc top margin on the horizontal annulus than top of cooker eyelid retractor of integration.
Second the device 492a that likewise, matches with the second burner 526b can be positioned in and receive on second dull and stereotyped central protrusion round platform 460a.Because of its arrangement is same as above-described two embodiments, so just no longer be repeated narration.
As previously mentioned, gas furnace of the present invention has two purposes, and first purpose is relevant for the effect attractive in appearance of gas furnace.Reaching this purpose is the structure that depends on gas furnace of the present invention, comprises having used two top panels 412 and 420.Be placed in the visual effect that gas furnace on the sales counter of kitchen has flat top surface because of its device that can cover vertical controlled heating capacity transmission makes, thereby coordinate mutually with the main visual effect of the transverse plane that comprises counter top in kitchen.
Second purpose is to improve the efficiency of heating surface of flame to cooker, is carbon dioxide thereby in the cooking, can practice thrift combustion gas with reducing emission greenhouse effect gas.For reaching the high efficiency of heating surface, must solve the relevant issues of this purpose of the left and right sides.
First problem is relevant for the loss that how to reduce heat in heat transfer process.Address this problem mainly is to rely on the device of the controlled heating capacity transmission of having used detachably and having removed and novel gas spout passage; Because this device can focus on the heat of flame on the cooker and this gas spout passage can be controlled the type of the flame of proper angle.
Second problem is relevant for how making the heat conduction become the principal mode in the cooker heating heat is transmitted.Address this problem is to have used to have the novel gas spout passage that points to inner surface to oblique upper.Form from this spout passage like this, promptly have with the identical top of this passage and just directly contacted the bottom of cooker to the flame of oblique upper orientation angle, thereby make have big during, heat conduction to become the principal mode that cooker is heated using combustion gas to the highest flow.This effective heat transmission for the cooker that is made of metal especially has superiority, because metal is the good conductor of heat, and the flame top that has maximum temperature in the case is the bottom that has directly contacted metal cooking appliance.In contrast, heat radiation and thermal convection current become the main form that the heat of the gas furnace of prior art is transmitted, thereby do not have the available heat transmission to metal cooking appliance.This is because there is many adverse factors, comprises that extending transversely, the cooling effect of flame and the cooker that is made of metal are photothermal bad absorbers.
The 3rd problem is relevant for when burning, how improving the clean-burning degree of burning mixture through having additional supply of auxiliary air.Address this problem and to set about from the notion that reduces the flow velocity of burning mixture when the ejection gas spout, reduce flow velocity in fact can using new gas spout passage of the present invention.Because this spout passage has the vertical section with the spout passage gas flow quadrature, that increase gradually by having the inner top surface that points to oblique upper.This space characteristics makes burning mixture reduce flow velocity gradually when in the spout passage, flowing, thereby has also just formed the low flow velocity that burning mixture had at the spout channel exit.
Burning mixture with low flow velocity has two big advantages for improving the efficiency of heating surface.The firstth, make the chemical reaction that more surrounding air participates in burning as auxiliary air.This advantage is vital for the abundant burning that obtains burning mixture, because than the speed of burning, the speed of supplying secondary air is the restraining factors in the kinetics of burning burning mixture.The flame that forms than the flame that is formed by burn incompletely, burning comparatively fully in addition has higher temperature, thereby can obtain the higher efficiency of heating surface to cooker.The second, therefrom the thermal medium that includes waste gas and air that produces also has corresponding low flow velocity, and this has just increased the time that this thermal medium contacts with cooker when the cooking, thereby has also just additionally increased the efficient of heating.
Three problems more than setting forth are obtaining solution by in 940 patent applications open, and the existing experimental result that can improve the efficiency of heating surface 23%.A kind of embodiment that is shown by Fig. 7 A like this; The present invention is provided with on the periphery of two top panels 412 and can selects that use, numerously lateral opening 416 and 417 accordingly, and it is used as to the burner superstructure provides the passage as the surrounding air of auxiliary air to reach the clean-burning purpose of burning mixture.
Attractive in appearance according to the present invention includes in interior spirit and purpose, except above-mentioned being placed in the air duct on two top panels, also have other embodiment.Said by Figure 17 A, numerous holes 415 has run through the downward frame 412a that is in positive front of first panel 412 '.Be placed in the 419 last times of shelf of the platy structure of gas furnace like this when the bottom of frame 412a, many holes 415 just can be used as the passage that surrounding air flows to the burner superstructure.Identically, also be connected downward frame with hole on positive back and the right of first top panel (promptly near burnt gas switch plate 436).Because of second top panel 420 ' and first top panel minute surface symmetry,, comprised illustrated hole 425 on the frame 420a of its front so many holes have also run through the downward frame of second panel.
Different with the pore space structure shown in Figure 17 A, Figure 17 B discloses and has been connected first top panel 412 " front edge 412x on the extended structure 413 of numerous downward weak point, such as similarly being downward short column.When the bottom of these extended structures is positioned in 419 last times of interior shelf of platy structure, just formed the passage that flows to the burner superstructure for surrounding air.Same extended structure (not diagram) also is connected on the positive back edge 412z and edge, right side 412y of this plate.This extended structure also can be arranged to second top panel 420 " the edge on.The smooth surface of shelf in the bottom that in addition, disclosed super heated rubber part 141 also can be positioned in extended structure respectively in Fig. 5 is protected.According to the imagination of above structure, the present invention can design particular structural on interior shelf 419, such as similarly being the top panel 412 ', 412 that groove limits said structure ", 420 ' and 420 " move, keep flowing of sufficient air simultaneously.At this moment, if needed, the surface of above-mentioned top panel can be designed to a little more than around the apparent height of frame 401.
The 4th problem is relevant for the uniformity that increases air mixture and primary air, because of mixed uniformly fuel gas is to obtain clean-burning fundamental.For address this problem, the present invention used the combustion gas disperser 636 and 642 that can broadly be defined as the combustion gas dispersal device; Broadly be defined as the gas mixer of air mixture and primary air, include the structure of the truncated cone hole connection cylindrical cavity in the gas-air inlet tube.
Fig. 8 A and 10A narrated use gas-air inlet tube 587, about the function of air mixture and primary air.According to aerodynamic principle, combustion gas 800 when in the truncated cone hole 600 of inlet tube 587, flowing to cylindrical cavity 592, has increased the flow velocity that upwards flows after spray nozzle of the gas supply 482 ejections.This is because of the truncated cone hole, in the cause that has reduced its area perpendicular to the horizontal section on combustion gas 800 flow directions gradually.Again according to aerodynamic principle, increased vacuum suction that the combustion gas 800 of flow velocity produced near be in the inlet tube 587 surrounding airs 802 got in the truncated cone hole 600 of this pipe, this inhaled air is so-called primary air.So just form the initial mixing of combustion gas 800 and primary air 802, and produced product gas: included the mixture of combustion gas and primary air and not mixed combustion gas and primary air.
Yet, when product gas flows through the interface 604 of two holes and after entering into cylindrical cavity 592, compares with its flow velocity in the truncated cone hole, it has reduced the speed that upwards flows sharp.This is the variation of area that comes from, changed into suddenly by the area of the less horizontal tangent plane of inner circumferential edge 602 representatives the bigger horizontal tangent plane of cylindrical cavity 592.In cylindrical cavity 592, near horizontal interior anchor ring 604 places, just produced the eddy current of gas this moment.And the phenomenon that forms eddy current has been aggravated the mixing of combustion gas 800 and primary air 802, helps producing mixed uniformly fuel gas.
The method of making gas-air inlet tube 587 as for other being used to is, can make a hollow cylinder in advance, and it has above-mentioned truncated cone hole 600.Process described gas-air inlet tube 587 among then this cylinder being pressed into ready-made in advance another cylindrical cylindrical cavity 592 in both sides.
It is understandable that the structure that connects cylindrical cavity except above-mentioned truncated cone hole; Other multiple structure also can be used to form the eddy current of gas, such as similarly being coarse inner surface of hole and the numerous horizontal protrusion on the vertical inner surface of hole, settled.So according to spirit of the present invention and purpose, any structure all is suitable, so long as they can promote to produce the mixing that the eddy current of gas strengthens combustion gas and primary air.In addition, these structures need to have flowing of barrier gas significantly.Under this regulation, can broadly define the gas mixer that these structures are air mixture and primary air.
Approach according to above-mentioned gas flow; The present invention has designed as disclosed numerous holes 433 in Fig. 7 B; They are positioned on the abutment wall of substructure 430 of gas furnace shell, and being utilized for surrounding air is the gas-air inlet tube 636 that flows to burner of primary air and 587 passage.
Know that again in the time of in just going into above-mentioned truncated cone hole, upwards the combustion gas 800 of flowing is the rotating shaft dense distribution along this hole, disperses to side direction gradually and naturally then.Because used combustion gas disperser 636 in the present invention, just at first can then be forced to disperse by the bottom tip 640 of disperser by its flank 638 along the combustion gas of upwards flowing 800 of rotating shaft dense distribution.Produce dispersed combustion gas like this, helped itself and the mixing of primary air.
It is favourable using the combustion gas disperser in the present invention, particularly helps when using liquefaction vapour, obtains all even well-mixed burning mixture.This is that liquefied gas has bigger mean molecule quantity because of the less mean molecule quantity than town gas, so they are not easy to be disperseed naturally after the container combustor that pressure is arranged.Here it is when using existing gas furnace, often causes the reason of burn incompletely because of bad gas-air troubled water.Under the effect of combustion gas disperser, gas furnace of the present invention can solve the phenomenon of liquefied gas burn incompletely, thereby makes it be applicable to liquefied gas and town gas.
Above-mentioned disclosed combustion gas disperser 636 can have various deformation.The first, it can have at least two flanks.The second, each sheet flank of at least two has the resemblance as the properller.The 3rd, according to spirit of the present invention and purpose, any frame for movement all is fit to, as long as it can disperse, but flowing of barrier gas significantly.On this meaning, above-mentioned structure can broadly be defined as the combustion gas dispersal device.
Be appreciated that, novel combustion gas spout passage of the present invention is not only on the top cover that is positioned in pyrosphere.As that kind of in second portion of the present disclosure, being narrated, they can also be positioned in and comprise on " ringwall 342 of the hollow stem 340 of burner " and obtain same effect.Described by Figure 15 A and 15B is the burner 650 of second embodiment of the present invention, has comprised bigger outer burning ring 651 and less interior pyrosphere 714.They have the above-mentioned position feature relevant for the arrangement of spout passage.
