Tehnični problemA technical problem

Glede na pomanjkljivosti dosedaj znanih plinskih gorilnikov, ki so v tem, da imajo sorazmerno velike dimenzi je po višini, zaradi česar niso primerni za vgradnjo v kuhalnike, ki zahtevajo čimbolj ploščato konstrukcijo; goril2 niki znanega tipa imajo prehode za dovod primarnega zraka odprte navzdol, kar povzroča, da je njihova montaža in centriranje težavna, razen tega pa imajo gorilniki po montaži slabo stabilnost in so izpostavljeni nehotenim premikom; nadalje je pomanjkljivost znanih gorilnikov v tem, da omogočajo brezhibno zgorevanje le pod določenimi pogoji pritiska in količine plina, se pred izumitelja postavlja tehnični problem, s kakšnimi konstrukcijskimi ukrepi ustvariti čimbolj ploščato konstrukcijo plinskega gorilnika, ki jo bo mogoče brez težav montirati in razstaviti in ki bo omogočala delovanje gorilnika pod različnimi tlaki in količinami plinaConsidering the disadvantages of the gas burners known so far, which are relatively large in size, they are tall in size, making them unsuitable for installation in cookers that require a flatter construction; burners of the known type have downstream intakes for the primary air inlet, making their mounting and centering difficult, except that the burners have poor stability after assembly and are subject to unintentional movement; furthermore, the disadvantage of known burners is that they allow flawless combustion only under certain conditions of pressure and gas, the inventor faces a technical problem with what design measures to create as flat a gas burner construction that can be easily mounted and disassembled and which will allow the burner to operate under different pressures and gas volumes

Stanje tehnikeThe state of the art

Znani so različni tipi plinskih gorilnikov za štedilnike in kuhalnike, ki pa imajo med drugim tudi to pomanjkljivost, da imajo sorazmerno velike dimenzije po višini, zaradi česar niso vedno primerni in se ne uporabljajo za take svrhe na področju kuhalnikov, kjer mora biti konstrukcija čim bolj kompaktna in ploščata.Various types of gas burners are known for cookers and cookers, but they also have the disadvantage of having relatively large dimensions in height, making them not always suitable and not used for such purposes in the field of cookers, where the construction should be as large as possible compact and flat.

Razen tega imajo gorilniki znanega tipa prehode za dovod primarnega zraka odprte navzdol ali točneje pod kuhalno ploščo oz. proti pečici, v primeru štedilnikov, v katerih je predvidena pečica, oz. proti komori ali kakršnekoli potrebne dovode, ki so izvedeni pod kuhalno ploščo.In addition, burners of a known type of primary air intake passage are open downwards or more precisely below the hob or. against the oven, in the case of cookers in which the oven is provided, or. against the chamber or any necessary inlets that are made under the hob.

Zaradi navedenega je montaža in centriranje gorilnikov znanega tipa zahtevna in težavna, razen tega pa imajo gorilniki po montaži dokaj slabo stabilnost in so izpostavljeni nehotenim premikom.Due to the above, the mounting and centering of burners of the known type is demanding and difficult, except that the burners have rather poor stability after installation and are subject to unintentional movements.

- 3 Razen tega je pri montaži in demontaži šobe ali plinskega injektorja sorazmerno težaven dostop in zahteva odstranitev ali dvig zgornje plošče priprave ali odstranitev čelnega dela, zaradi Česar to operacijo nikakor ni mogoče opraviti na lahek način.- 3 In addition, access and mounting of the nozzle or gas injector is relatively difficult to access and requires removal or lifting of the upper appliance panel or removal of the front end, making this operation in no way easy.

Navedeni znani gorilniki imajo razen tega sorazmerno toge možnosti delovanja in sicer v tem smislu, da omogočajo brezhibno zgorevanje le pod določenimi pogoji pritiska in količine plina, kar preprečuje prilagajanje takih gorilnikov na vsako pripravo in zahteva, da imamo celo vrsto različnih gorilnikov, ki bi lahko ustregli različnim zahtevam.These known burners also have relatively rigid operating capabilities in that they allow flawless combustion only under certain conditions of pressure and gas volume, which prevents the adaptation of such burners to any device and requires that we have a range of different burners that could meet different requirements.

Opis rešitve tehničnega problema s primeri izvedbe ter seznamom slikA description of the solution to a technical problem with examples of execution and a list of images

Glede na predhodno obravnavani tehnični problem bo le-ta rešen s plinskim gorilnikom za štedilnike in kuhalnike, ki bodo v splošnem sestavljeni iz elementov z enostavno kombinacijo, ki bodo lahko dostopni, ki jih bo mogoče brez težav razstaviti in ki ne bodo imeli predhodno navedenih pomanjkljivosti dosedaj znanih izvedb.In view of the technical problem discussed above, it will be solved with a gas burner for cookers and cookers, which will generally consist of easy-to-access, easily disassemble elements that do not have the foregoing disadvantages known performances to date.

Nadalje je rešitev v smislu izuma v tem, da ustvari gorilnik za predhodno navedene namene, pri čemer bo sestavljen iz elementov, ki so izoblikovani za dosego t.im. venturijevega učinka pri mešanju in razdeljevanju plina, pri čemer bo navedeni učinek dosežen v bistvu med nosilcem elementa za razdeljevanje plamena in samim elementom za razdeljevanje plamena, pri čemer prostor, ki je omejen s predhodno omenje4 nima elementoma poteka v radialni smeri in v krožnem smislu začenši od središča ter odtok proti luknjam navedenega elementa za razdeljevanje plina. To omogoči znatno prilagodljivost uporabe gorilnika, kar omogoča vzdrževanje brezhibnega in popolnega zgorevanja tudi pri znatnih variacijah tlaka plina in pri kakršnikoli vrsti plina. Razen tega je gorilnik mogoče prilagoditi kakršnikoli zahtevi uporabe in sega lahko uporabi v poljubnem štedilniku ali kuhalniku.Further, the solution of the invention is to create a burner for the aforementioned purposes, wherein it will consist of elements designed to achieve the so-called. venturi effect in gas mixing and distribution, said effect being achieved essentially between the carrier of the flame dispenser and the flame dispensing element itself, wherein the space limited by the foregoing 4 does not have radial and circular starting elements from the center and the drain against the holes of said gas distribution element. This allows for considerable flexibility in the use of the burner, which enables the maintenance of flawless and complete combustion even with significant variations in gas pressure and in any type of gas. In addition, the burner can be adapted to any requirement of use and can be used in any stove or cooker.

Nadaljnji namen izuma je, da ustvari plinski gorilnik zelo zmanjšanih dimenzij po višini, tako da ga bo mogoče s pridom uporabiti za'kuhalnike, ki morajo biti ploski in ki morajo imeti čim manjšo višino, ki se bo skladala z zahtevami namestitve samega kuhalnika.It is a further object of the invention to create a gas burner of very small dimensions in height, so that it can advantageously be used for cookers which must be flat and have a minimum height that meets the requirements of the installation of the cooker itself.

Rešitev v smislu izuma je nadalje v tem, da se ustvari gorilnik, ki bo omogočil sesanje primarnega zraka mešanice od zunaj in direktno nad ploščo štedilnika ali nad ploščo kuhalnika, s čimer odpade potreba po izoblikovanju zaprte in ločene komore ali dovodov zraka pod navedeno ploščo, kar je bila običajna izvedba pri konvencionalnih plinskih gorilnikih.The solution according to the invention is further to create a burner which will allow the primary air of the mixture to be sucked in from outside and directly above the cooker hob or above the hob, thus eliminating the need to create a closed and separate chamber or air inlet under said hob, which was the usual design for conventional gas burners.

Nadaljnji cilj izuma je, da ustvari plinski gorilnik za predhodno omenjene namene, ki ga bo lažje namestiti, centrirati, ki bo bolj stabilen bodisi pri neposredni uporabi na kuhalni plošči štedilnika ali na kuhalniku, bodisi da je nameščen na prečki, ki je predvidena pod navedeno ploščo. Gorilnik po izumu je razen tega lahko opremljen z elementom za razdeljevanje plamena običajne izvedbe, zaradi česar ga je mogoče brez težav nabaviti.It is a further object of the invention to create a gas burner for the aforementioned purposes which will be easier to install, centering, which is more stable either when used directly on the hob or on the stove, or mounted on the crossbar provided under the foregoing plate. The burner of the invention may furthermore be provided with a flame dispenser of the conventional design, making it easily obtainable.

Nadaljnji cilj in prednosti gorilnika v smislu izuma bodo podrobneje obrazloženi v nadaljnjem opisu na osnovi izvedbenega primera in pripadajočih načrtov, v katerih kaže sl. 1 izvedbeni primer kuhalne plošče, opremljene s plinskimi gorilniki, sl. 2 sklop gorilnika po izumu, nameščenega neposredno na kuhalni plošči s sesalnimi prehodi primarnega zraka, katerih odprtine so nad kuhalno ploščo, sl. 3 delni prerez po črti III-III iz sl. 2.The further object and advantages of the burner according to the invention will be explained in more detail in the following description based on the embodiment and associated plans, in which FIG. 1 shows an example of a hob equipped with gas burners; FIG. 2 shows an assembly of a burner according to the invention mounted directly on the hob with primary air intake ports whose openings are above the hob, FIG. 3 is a partial section along line III-III of FIG. 2.

Gorilnik po izumu obsega injektor ali šobo 1 za plin, ki je montirana na nosilcu 2, ki ima vod 3, ki je s pomočjo cevnega priključka 4 povezan s cevjo (ki v načrtu ni prikazana) za dovod plina.The burner according to the invention comprises a gas injector or nozzle 1 mounted on a carrier 2 having a conduit 3 connected to the gas supply pipe (not shown) by a pipe connection 4.

Pri izvedbi po sl. 2 in 3 je injektor ali šoba 1 nameščena v komori 5, ki jo določa del tulke 6, katere os poteka vertikalno. Navedena komora 5 je navzgor odprta, njeno dno pa je zaprto s steno 7. Tulka 6 ima po obodu navzven štrlečo izvedeno prirobnico 8, s pomočjo katere je pritrjen nosilec 2 s šobo 1 na ploščo 9, ki tvori zgornjo ploščo plinskega štedilnika ali kuhalno ploščo 9 v pravem pomenu bsede. Pritrditev prirobnice 8 na navedeno ploščo 9 je izvedena z vijaki 10 z vmesno vstavitvijo tesnila 11.In the embodiment of FIG. 2 and 3, the injector or nozzle 1 is housed in a chamber 5 defined by a portion of the sleeve 6 whose axis extends vertically. Said chamber 5 is open upwards and its bottom is closed by wall 7. The hub 6 has a projecting flange 8 extending outwards, by means of which a carrier 2 is attached with a nozzle 1 to the plate 9 which forms the top plate of the gas cooker or hob. 9 in the truest sense. The mounting of the flange 8 to said plate 9 is accomplished by screws 10 with the intermediate insertion of the seal 11.

Tulki 6 nosilca 2 je na razstavljiv način pridruženo telo 12, ki služi kot nosilec za razdelilnik 13 plamena, ki je po sebi znan. Navedeno telo 12 ima središčni cevni del 14, ki omejuje prehodno luknjo 15, katere os poteka vertikalno in ki ima na zunanji strani centrirna radialna rebra 16.The sleeve 6 of the carrier 2 is in a disassociable manner an associated body 12 that serves as a carrier for the flame distributor 13, which is known in itself. Said body 12 has a center tube portion 14 which restricts the through hole 15, the axis of which extends vertically and which has centering radial ribs 16 on the outside.

- 6 Cevni del 14 poteka navzdol in sega v komoro 5 nosilca 2, ne da bi prispel do stene 7 dna. Navedena radialna rebra 19 služijo za centriranje cevnega dela 14 v tulki 6, pri čemer omejujejo med seboj vertikalne prehode 16*.- 6 The tubing 14 extends downwards and extends into the chamber 5 of the carrier 2 without reaching the bottom wall 7. Said radial ribs 19 serve to center the tubing 14 in the sleeve 6, limiting the vertical crossings 16 *.

Telo 12 ima del z robom 17, ki je obrnjen navzdol, tako da je nasproti plošče 9, od katere je sicer oddaljen, tako dao mejuje obodni krožni prehod 18 za vstop primarnega zraka, ki je potreben za ustvaritev mešanice zrale in plina in za zgorevanje plina.The body 12 has a portion with the edge 17 facing down so that opposite the plate 9, from which it is otherwise spaced, thus circumscribes the circumferential circular passage 18 for the intake of primary air required to create a mixture of grain and gas and for combustion gas.

Pod telesom 12 med središčnim cevnim delom 14 in obodnim delom so izvedena radialna rebra 19, ki tvorijo naslonsko ravnino za telo 12, na zgornjem robu tulke 6 nosilca 2, ki nosi šobo 1. Navedena rebra 19 omejujejo radialne prehode 19* tako da od zunaj vsesani zrak, ki vstopa skozi obodni krožni prehod 18 prehaja preko zgornjega robu tulke 6 in nato teče navzdol skozi prehode 16‘proti dnu komore 5, od koder se dviga skozi središčno luknjo 15 telesa 12.Below the body 12 between the center tube 14 and the circumferential part, radial ribs 19 are formed, forming an abutment plane for the body 12, at the upper edge of the sleeve 6 of the carrier 2 carrying the nozzle 1. The said ribs 19 restrict the radial crossings 19 * so that from the outside the intake air entering through the circumferential circular passage 18 passes through the upper edge of the sleeve 6 and then flows down through the passages 16 'towards the bottom of the chamber 5, from which it rises through the center hole 15 of the body 12.

Tok primarnega zraka je v sl. 2 nakazan s puščicami.The primary air flow is in FIG. 2 indicated by arrows.

Na ta način se primarni zrak sesa od zunaj gorilnika neposredno nad kuhalno ploščo 9, s čimer so doseženi uvodoma omenjeni cilji in s čimer je dobljena mešanica plina in zraka v komri 5 in v luknji 15 razdelilnika 13 plamena.In this way, the primary air is sucked in from the outside of the burner directly above the hob 9, thereby achieving the above-mentioned goals and thus producing a gas / air mixture in the chamber 5 and in the hole 15 of the flame distributor 13.

Navedeno telo 12 ima razen tega v svojem srednjem zgornjem delu centrirni krožni sedež 20, v katerega oblikovno sklepno vprijema in ob katerem je centriran razdelilnik 13 plamena, ki pokriva središčno luknjo 15.In addition, said body 12 has a centered circular seat 20 in its upper middle region, into which it forms a joint and which has a centered flame distributor 13 covering the center hole 15.

V smislu izuma sta zunanja ploskev 12’ telesa 12 in notranja ploskev 13’ razdelilnika 13 plamena, ki sta druga nasproti druge glede na zahteve tlaka plina, ki je predviden za zgorevanje, glede na vrsto plina itd. , lahko izvedeni tako, da potekata paralelno ali pa konvergentno začenši od središča proti zunanjosti oz. proti vrsti lukenj 21 razdelilnika 13 plamena. V obeh slučajih navedeni površini 12’ in 13’, ki si stojita druga nasproti druge omejujeta radialni prehod 22, skozi katerega priteka mešanica plina in zraka, ki se ustvari v središčni luknji 15 in se dovaja k razdelilniku plamena, kjer se izvrši zgorevanje in po venturijevem učinku zmanjša hitrost ter pridobi na pritisku, bodisi zaradi oblike prehoda 22, kadar je ta izveden divergent no, bodisi zato, ker se presek prehoda veča v odvisnosti od radija, ki se začenja v središču in poteka navzven. Na ta način bo mešanica razdeljena in njeno zgorevanje je pravilno in popolno, tudi če imamo opravka z znatnimi spremembami tlaka in ne glede na to, kakšen je plin, ki ga uporabljamo.According to the invention, the outer face 12 'of the body 12 and the inner face 13' of the flame distributor 13 are opposite to each other according to the pressure requirements of the gas to be combusted, depending on the type of gas, etc. , can be designed to run in parallel or converge from the center to the outside or. against a series of holes 21 of the flame distributor 13. In both cases, said surfaces 12 'and 13', facing each other, limit the radial passage 22 through which the gas / air mixture generated in the center hole 15 flows and is fed to the flame distributor for combustion and the venturi effect is reduced in speed and obtained by pressure, either because of the shape of the passage 22 when it is divergent, or because the cross section of the passage increases depending on the radius starting at the center and extending outwards. In this way, the mixture will be distributed and its combustion is correct and complete, even when dealing with significant pressure changes and no matter what kind of gas we use.

V središču luknje 15, ki je omejena s cevnim delom 14 telesa 12 je lahko smotrno nameščen regulator primarnega zraka, pri čemer je ta regulator izveden kot pomična puša 23, ki jo je mogoče pozicionirati v navedeni luknji 15 s pomočjo blokirnega vijaka 24, s katerim se spreminja višina oz. oddaljenost puše 23 od dna komore 5, kot kaže sl. 2.In the center of the hole 15, which is bounded by the tubular portion 14 of the body 12, a primary air regulator may be conveniently mounted, the regulator being configured as a movable sleeve 23, which can be positioned in said hole 15 by means of a locking screw 24, by which the height or height changes. the distance of the bush 23 from the bottom of the chamber 5, as shown in FIG. 2.

V zgornjem delu luknje 15 je lahko predviden tudi ovratnik ali nastavek ki omejuje premaknitev puše 23 navzgor, tako da ta puša ne more popolnoma zapreti prehod 22.An upper collar or attachment may also be provided in the upper portion of the hole 15, which restricts the movement of the bush 23 upwards so that this bush cannot completely close the passage 22.

V vsakem primeru in kot je bilo predhodno že opisano in prikazano v načrtih, ima gorilnik po izumu zelo majhno višino, razen tega pa je po odstranitvi razdelilnika 13 plamena ter pripadajočega pridruženega telesa 12 lahko brez težav prižgati plin neposredno na šobi 1 v primeru njene zamenjave, ne da bi pri tem morali spremeniti položaj plošče 9. Na isti način so brez težav dostopna od zgoraj tudi sred stva za regulacijo količine plina, ki npr. obstoje iz loput 30, ki je vstavljena v dovod 3 plina, kot je to prikazano v sliki 3.In each case, and as previously described and shown in the drawings, the burner according to the invention has a very small height, except that after removal of the flame distributor 13 and the associated associated body 12 it is easy to ignite the gas directly on the nozzle 1 in case of replacement , without having to change the position of the plate 9. In the same way, gas regulators are easily accessible from above. exist from the flaps 30 inserted into the gas inlet 3, as shown in Figure 3.

Navedba o najboljšem izumitelja znanem načinu za gospodarsko izkoriščanje izumaAn indication of the best inventor of the known method for the economic exploitation of the invention

Pri realizaciji plinskega gorilnika za štedilnike in /In realization of gas burner for cookers and /

kuhalnike po izumu je potrebno upoštevati naslednje:The cookers according to the invention should take into account the following:

Soba 1 za plin je izdelana iz vlečene okrogle medeninaste palice, pri kateri ima material iz medenine oznako 0T58 po italijanskem standardu UNI 2012. Obdelava je izvršena na stružnici, izvrtine so vrtane in kalibrirane s prevlečnim strugalom na stroju TransfertThe gas room 1 is made of a drawn round brass rod with brass material marked 0T58 according to the Italian standard UNI 2012. The work is performed on a lathe, the holes are drilled and calibrated using a transfert coated lathe.

Nosilec 2 je izveden v enem kosu na način brizganega liva iz zlitine GD-AL Si 12 Cu 2Fe po italijanskem standardu UNI 5076-74. Ulitek je nato obdelan na strojih Transfert samo na mestih, kjer so predvideni navoji.The carrier 2 is made in one piece in the manner of injection molded cast iron alloy GD-AL Si 12 Cu 2Fe according to the Italian standard UNI 5076-74. The casting is then treated on Transfert machines only at the locations where the threads are provided.

Telo 12 je izvedeno iz zlitine Pyral N.2 po italijanskem standardu UNI 6253/68 na način brizganega livanja. Ulitek je nato stružen ter brušen in poliran na zunanji strani Razdelilnik 13 plamena je izveden iz medenine v kvaliteti DT58 po italijanskem standardu UNI 2012, z ekstrudiranjem. Ekstrudirani polizdelek se nato obdela na stružnici, nakar je vrtan na specialnem vrtalnem stroju s krožno razporeditvijo vrtalnih glav.The body 12 is made of Pyral N.2 alloy according to the Italian standard UNI 6253/68 by injection molding. The cast is then turned and sanded and polished on the outside. The flame distributor 13 is made of brass in DT58 quality according to the Italian standard UNI 2012, by extrusion. The extruded semi-finished product is then machined on a lathe, after which it is drilled on a special drilling machine with a circular arrangement of drilling heads.

Pomična puša 23 regulatorja primarnega zraka je izdelana iz polizdelka - železne cevi, ki ne potrebuje nobene posebne naknadne obdelave.The movable sleeve 23 of the primary air regulator is made of a semi-finished product - an iron pipe that does not require any special post-processing.

V naslednjem bomo podali izdelovalne tolerance pri posameznih elementih plinskega gorilnika po izumu:In the following we will give manufacturing tolerances for individual elements of the gas burner according to the invention:

-ΛΟTolerance šobe 1 za plin so 6 g po italijanskem standardu UNI 5542.65. Na navoju + 0,1 na celotno dolžino in +_ 3% na vrednost kaiibrirane izvrtine-ΛΟTolerance nozzles 1 for gas are 6 g according to the Italian standard UNI 5542.65. On thread + 0.1 on full length and + _ 3% on value of calibrated bore

Tolerance za nosilec 2 in telo 12 so: + 0,15 na linearne dimenzije in _+ 30’ na kotne izmere.The tolerances for bracket 2 and body 12 are: + 0.15 on linear dimensions and _ + 30 'on angular dimensions.

Tolerance za razdelilnik plamena so: +-0,1 na višino, + 0 0,2 na zunanje premer in + 0,03 na izvrtine.The tolerances for the flame distributor are: + -0.1 in height, + 0 0.2 in outside diameter and + 0.03 in bore.

Pomična puša 13 regulatorja primarnega zraka nima nekih posebnih toleranc za vstavitev v luknjo 15.The movable sleeve 13 of the primary air regulator does not have any special tolerances for insertion into the hole 15.

Zaporedje pri montaži posameznih elementov je naslednje: Najprej se šoba 1 uvije na nosilec 2, nato se kontrolira tesnenje tega uvitega spoja s tem, da se zamaši kalibrirano izvrtino šobe 1, dočim se skozi cevni priključek dovaja zrak za preizkušanja tesnosti uvitja šobe 1 v nosilcu 2.The sequence of mounting of the individual elements is as follows: First, the nozzle 1 is screwed onto the carrier 2, then the sealing of this twisted joint is controlled by clogging the calibrated bore of the nozzle 1, supplying air through the pipe connection to test the tightness of the twisting of the nozzle 1 in the carrier 2.

Sestavljeni sklop nosilca 2 s šobo 1 se nato s pomočjo vijakov 10 pritrdi na ploščo 9 štedilnika. Pri tem se v telo 12 predhodno vstavi pomično pušo 23 za reguliranje primarnega zraka in se jo pritrdi z radialnim vijakom 24. Nato se od zgoraj na nosilec 2 montira telo 12, končno pa se na telo 12 centrirno namesti razdelilnik 13 plamena.The assembled carrier assembly 2 with nozzle 1 is then secured to the plate 9 by the screws 10. In this case, a movable sleeve 23 is first inserted into the body 12 for regulating the primary air and secured by a radial screw 24. The body 12 is then mounted on top of the carrier 2, and finally a flame distributor 13 is centrally mounted on the body 12.

SUMMARY

The invention relates to a gas burner for cookers and cookers, which solves the problem of the operation of the burner under different pressures and different amounts of gas and offers the most flat design gas burner, which allows easy installation and disassembly and consisting of a carrier 2 in the bottom of which is wound nozzle 1 for gas extending into the gas line 3, and that on the outside of the carrier 2 bounding the chamber 5, a flange 8 is attached to the plate 9 of the cooker. In the sleeve 6 of the carrier 2 is a tube part 14 of the associated body 12 whose radial ribs 16 are adjacent to the inner wall of the sleeve 6, and its horizontal radial ribs 19 are resting against the upper edge of the sleeve 6, thereby determining the circumferential circular passage 18 for air between associated bodies 12 and hob 9.

In the pipe section 14, the height adjustable o

bushing 23, which is secured by a screw 24 screwed into the rib 16 and the pipe portion 14. The associated body 12 has a passage hole 15 at the upper center in the center for passage of the gas / air mixture, and a centered circular seat 20 is formed at the upper part, in which engages the flame distributor 13, which covers the central passage hole 15, and with the associated body (12) limits the radial passage 22 for the air-gas mixture.
