Abstract

Onto the lid (14) of the lower part of the electric hotplate (11) there's a side connecting sheet metal (20) attached by riveting or similar. The penetrating part (25) or other functional part is located in the lid (14) openings (26, 27) and the side connecting sheet metal (20) in such a way, that it rests with appropriately side staggered adapters (32, 35) each time on one of both sheet metal parts, so that by connecting both parts it is attached together with them. This way it creates a mounting unit suitable for automating the installation of hotplates.

Description

Običajna izvedba kuhalne plošče (DE-B-26 51 848 ustrezno AU-A-512 394) ima na spodnjem pokrovu stransko štrlečo priključno pločevino, na katere koncu je nameščeno priključno sredstvo, npr. izolacijsko telo z vijačnimi priključki. Skozi odprtino v pokrovu in priključni pločevini, ki sta v področju odprtine medsebojno povezani s prepogibom jezikov, štrli prehodno sredstvo v obliki izolacijskega telesa s prehodnimi odprtinami za priključne vodnike, ki se opira na spodnjo stran kuhalne plošče in je s tem pričvrščeno. Postalo je tudi znano, da se pričvrsti na ta način druge funkcijske sestavne dele, ki prehajajo skozi pokrov, torej prehodna sredstva, npr. temperaturni omejilnik (EP-B-45 007 ustrezno US-A-43 86 263). Pričvrstitev prehodnega sredstva je bila izvedena tudi že brez opiranja na notranjo stran neposredno na pokrovu brez na njem predvidene priključne pločevine z v poglobitve vprijemajočimi jeziki na prekrivni pločevini (DE-A-36 29 549 ustrezno US-A-48 08 797). Nadalje obstajajo prehodna sredstva, ki jih držijo v položaju samo priključni vodniki, ki potekajo skozi njih (DE-A-26 20 004 ustrezno US-A-41 22 330).Typically, the hob (DE-B-26 51 848 corresponding to AU-A-512 394) has a side projecting terminal plate on the lower lid, at the end of which a connection means is mounted, e.g. insulating body with screw connections. Through the opening in the lid and the connection plates, which are interconnected in the area of the opening with the tongue bend, protrude a transitional means in the form of an insulating body with transitional openings for the connection leads, which rests on the underside of the hob and is thus secured. It has also become known that other functional components that pass through the cover, i.e. transitional means, e.g. temperature limiter (EP-B-45 007 corresponding to US-A-43 86 263). Attachment of the transient means was also carried out without relying on the inside directly on the cover without the connecting plate provided with recessed tongues on the cover plate (DE-A-36 29 549 corresponding to US-A-48 08 797). Furthermore, there are transient means which are held in position by only the connecting conductors passing through them (DE-A-26 20 004 corresponding to US-A-41 22 330).

Vsa ta oprema je glede na funkcijo brez pripomb, vendar se naj bi pri izdelavi in montaži poboljšala. Posebno avtomatična montaža je ovirana s tem, da sta potrebna pri nekaterih izvedbah dva poteka pritrjevanja, namreč za priključno pločevino in za prehodno sredstvo, in je pri drugih izvedbah potrebna, deloma pred namestitvijo pokrova, vstavitev in natančno pozicioniranje prehodnega sredstva.All of this equipment is unremarkable in function, but it is expected to improve in production and installation. Particularly automatic installation is hampered by the fact that in some embodiments, two fixing runs are required, namely for the connection plate and the transient means, and in other embodiments, partly before the cover is fitted, the insertion and precise positioning of the transient means.

Naloga izuma je poenostavitev montaže pri električni kuhalni plošči. Rešena je z zahtevkom 1.It is an object of the invention to simplify the installation of an electric hob. It is solved by claim 1.

Prehodno sredstvo je zaradi povezave med pokrovom in priključno pločevino oblikovno-sklepno med obema zapahnjeno. To bi se lahko izvedlo s prirobnico, ki je vključena med pločevine. Prednostno pa je, da se izvede za izmenoma navzgor in navzdol usmerjena oporna ramena zapahnitev na nastavkih prehodnega sredstva praktično v eni ravnini. Ta izvedba se lahko izvede posebno enostavno tudi v keramičnem materialu, npr. steatitu in zahteva samo različno oblikovane prehodne odprtine skozi pokrov in priključno pločevino, da bi se izvedlo zapahnitev avtomatično, ne da bi bile za to potrebne izbokline ali podobno.Due to the connection between the cover and the connection plate, the transition means is locked between the two joints. This could be done with a flange included in the sheet metal. It is advantageous, however, to lock the support arms alternately upward and downward at locking points of the transient means in virtually one plane. This embodiment can also be made particularly easy in ceramic material, e.g. steatite and requires only differently shaped openings through the lid and the connection plate to lock it automatically without the need for bulges or the like.

S tem se lahko pokrov, zaključna pločevina in prehodna sredstva pred njihovo namestitvijo na kuhalno ploščo zajamejo v povezano montažno enoto. Če vsebujejo prehodna sredstva prehode za priključne vodnike, je potrebno to enoto samo natakniti na narobe ležečo kuhalno ploščo tako, da preidejo priključni vodniki skozi odprtine. Izognemo se nizanju posamičnih delov in naknadni povezavi. V odvisnosti od oblikovanja prehodnih sredstev, pokrova in priključne pločevine lahko poteka montaža prehodnega sredstva s poljubne strani in sicer prednostno popolnoma avtomatično. Povezava pokrova in priključne pločevine, ki pričvrščuje istočasno prehodno sredstvo, lahko poteka z zakrivitvijo pločevinastih jezikov v robnem področju odprtin ali tudi s kovičenjem na drugem mestu, prednostno s kovičanjem z enakim materialom.In this way, the lid, the end plate and the transitional means can be captured in a connected mounting unit before being mounted on the hob. If the transient means for the conductors are connected, it is only necessary to attach this unit to the wrong hob so that the connection cables pass through the openings. Avoiding picking up individual parts and subsequent connection. Depending on the design of the transient means, the cover and the connection plate, the transitional means can be mounted from any side, preferably fully automatic. The connection between the lid and the connecting plate, which secures the transition material at the same time, can be achieved by curving the sheet tongues in the edge region of the openings or by riveting elsewhere, preferably by riveting with the same material.

Te in nadaljne značilnosti prednostnih nadaljnjih oblikovanj izuma izhajajo razen iz zahtevkov tudi iz opisa in risb, pri čemer se lahko posamične značilnosti uresničujejo pri izvedbeni obliki izuma in na drugih področjih vsakokrat same zase ali več skupaj v obliki podkombinacij in lahko predstavljajo prednostne ter same zase zaščite sposobne izvedbe, za katere se tukaj zahteva zaščita. Izvedbeni primeri izuma so prikazani v risbah in bodo v nadaljnjem podrobneje pojasnjeni.

Sl. 1 prikazuje električno kuhalno ploščo 11 s telesom 12 kuhalne plošče in v položaju uporabe zgoraj nahajajočo se kuhalno ploskvijo 13. V položaju uporabe spodnja, v risbah pa vsakokrat gornja stran kuhalne plošče je zaprta s pokrovom 14, obstoječim iz profiliranega pločevinastega štancanega dela, ki se opira z zunanjim robom 15 znotraj vlivnega roba 16 na spodnjo stran kuhalne plošče, to je vložitven prostor ogrevanja. Pričvrstitev poteka prek uvitega središčnega sornika 17, prek katerega poteka tudi pritrditev kuhalne plošče na kuhalno korito ali štedilnik s pomočjo matice 18. Prekrivna pločevina je lahko oblikovana različno, tako da lahko nalega npr. tudi na robu 16 ali pa je pričvrščena središčno z drugimi pritrdilnimi sredstvi.FIG. 1 shows the electric hob 11 with the hob body 12 and in the position of use above the hob 13. In the lower operating position, in each drawing, the upper side of the hob is each closed by a lid 14 made of profiled sheet metal part which it rests with the outer edge 15 inside the pouring edge 16 on the underside of the hob, which is the space for heating. The attachment is via a twisted center bolt 17, through which the hob is mounted on the hob or cooker by means of a nut 18. The overlay can be formed in different ways so that it can fit e.g. also at edge 16 or attached centrally by other fasteners.

Na izbočenju 19 pokrova 14 je pritrjena priključna pločevina 20, ki ima stranske ojačitvene zapognitve 21 in štrli od svojega pritrdilnega mesta, ki leži relativno daleč izven središča kuhalne plošče, približno radialno navzven. Na svojem prostem koncu je nameščeno priključno sredstvo 22 v obliki izolacijskega kosa, ki vsebuje npr. vijačne sponke, s katerimi se lahko na že nekoliko izven visokotemperaturnega področja ležečem mestu povežejo masivni priključni vodniki 23 kuhalne plošče s tokovnimi dovodniki 24. Priključno sredstvo lahko vsebuje poljubne priključne naprave, kot vtične priključke itd. in/ali sprejme tudi temperaturna tipala itd., ki so priključena na kuhalno ploščo oz. njene dovode.On the protrusion 19 of the lid 14 is attached a connecting plate 20 having lateral reinforcing bends 21 and projecting from its attachment position, which lies relatively far beyond the center of the hob, approximately radially outwards. At its free end is mounted an attachment means 22 in the form of an insulating piece containing e.g. screw terminals, which can be used to connect to the outside of the high temperature area a massive connection conductors 23 of the hob with the current feeders 24. The connection means may contain any connection devices, such as plug connections, etc. and / or accepts temperature sensors, etc., which are connected to the hob or. her leads.

Na tistem koncu priključne pločevine 20, ki je na strani kuhalne plošče, štrlijo priključni vodniki 23 skozi skoznjiško sredstvo 25, ki je oblikovano kot telo iz toplotno obstojnega izolacijskega materiala, npr. steatita ali drugih keramičnih materialov. To štrli skozi odprtini 26, 27 v pokrovu 14 in priključni pločevini 20 in je s tem pričvrščeno (sl. 9).At that end of the connection plate 20, which is on the side of the hob, the connecting conductors 23 protrude through the through means 25, which is formed as a body of heat-resistant insulating material, e.g. steatite or other ceramic materials. This protrudes through the openings 26, 27 in the cover 14 and the connection plate 20 and is thereby fastened (Fig. 9).

Pričvrstitev je prikazana na osnovi sl. 2 do 8. Odprtina 26 v pokrovu 14 ima obliko podolgovate luknje, ki obsega na svojih obeh vzdolžnih straneh po en razširjujoč se izrez 28.The attachment is shown on the basis of FIG. 2 to 8. The opening 26 in the lid 14 is in the form of an elongated hole, comprising on one of its longitudinal sides one extending recess 28.

Odprtina 27 v priključni pločevini 20 ima razpotegnjeno pravokotno obliko z zaobljenimi vogali z večjo širino, kot so izmere podolgovate luknje odprtine 26 v robnem področju in izstopajoči odseki 29 v vzdolžnem središčnem področju, tako da je odprtina 27 tam ožja kot odprtina 26 v področju izreza 28.The opening 27 in the connecting plate 20 has a rectangular extension with rounded corners of greater width than the dimensions of the elongated hole of the opening 26 in the edge region and the protruding sections 29 in the longitudinal center region so that the opening 27 there is narrower than the opening 26 in the cutout area 28 .

Oblika prehodnega sredstva 25 je razvidna iz sl. 3 in 5 do 7. Gre za sorazmeroma ozko telo, v katerem so predvidene v vrsti štiri okrogle prehodne odprtine 30, ki se v smeri navzdol lijakasto širijo in obsegajo uvajalne poševnine. V področju, ki je v risbi zgoraj (v položaju uporabe spodaj), se nahajajo na ozkih straneh 31 kot prirobnica oblikovani nastavki 32, katerih spodnje strani tvorijo oporna ramena 33. Ti segajo samo malo v področje vzdolžnih strani 34, v katerih središčnem področju je na vsaki strani predviden nastavek 35, ki se razteza od druge (v sliki spodnje) strani navzgor in ima v isti ravnini z opornimi rameni 33 svojo gornjo omejitev, ki prav tako tvori oporno ramo 36. Dodatno je v področju višine nastavkov 33 v priključku na nastavek 35 predvidena še majhna poglobitev 37 vzdolžnih strani 34. Oblika prehodnih sredstev je razvidna tudi iz v različnih ravninah izvedenih prerezov (sl. 6 in 7).The shape of the transient means 25 can be seen in FIG. 3 and 5 to 7. It is a relatively narrow body in which there are four circular passage openings 30 arranged in a row, which extend funnelwise downwards and comprise introductory slopes. In the area shown in the drawing above (in the position of use below), there are flanges 32 formed on the narrow sides 31, with the lower sides forming the support arms 33. These extend only slightly into the area of the longitudinal sides 34, in which the central area is provided on each side is a nozzle 35 extending from the other (in the lower picture) upwards and having its upper rest in the same plane with the supporting shoulders 33, which also forms a support arm 36. Additionally, in the area of the height of the nozzles 33 in the connection to nozzle 35 provides a slight recess 37 of the longitudinal sides 34. The shape of the transitional means is also evident from the cross sections made in the different planes (Figs. 6 and 7).

Oblika priključne pločevine 20 v področju odprtin je razvidna iz sl. 4. V področju odprtine je nekoliko trapezasto razširjena in ima razen ojačitvenih zapognitev 21 ojačitvene obrobke 38.The shape of the connecting plate 20 in the area of the openings is shown in FIG. 4. In the area of the opening, it is slightly trapezoidal and, with the exception of reinforcement barriers, 21 has reinforcing edges 38.

Oblika odprtin 26, 27 je v sodelovanju s tisto od skoznjiškega sredstva 25 izbrana tako, daje možen naslednji montažni postopek: prehodno sredstvo 25 se lahko uvede od zgoraj v odprtino 26. Pri tem preide spodnji del telesa 39 prehodnega sredstva in oba stranska nastavka 35 skozi odprtino 36 (torej v sl. 7 v preseku prikazan odsek), dokler ne nalegajo ozkostranska robna področja 40 od odprtine 26 na opornih ramenih 33.The shape of the openings 26, 27, in cooperation with that of the bypass means 25, is selected such that the following assembly procedure is possible: the passage means 25 may be introduced from above into the opening 26. In doing so, the lower part of the body 39 of the passage means and the two side attachments 35 through aperture 36 (thus the section shown in section in cross-section) until the narrow-angled edge regions 40 of the aperture 26 on the support arms 33 rest.

Zatem se položi priključna pločevina 20 od zgoraj prek skoznjiškega sredstva, kar je možno, ker je v področju nastavkov 32 ustrezno veliko izrezana. Opira pa se sicer s svojimi izstopajočimi odseki 29 na opornem ramenu 36 nastavka 35, tako da nastopa sedaj opiranje na po enega od obeh pločevinastih delov 14, 20 v druga proti drugi nasprotnih smereh, in sicer na osnovi druga proti drugi nasprotno usmerjenih opornih ramen 33 in 36.Thereafter, the mounting plate 20 is laid over from above through the through means, which is possible because it is adequately cut in the region of the attachments 32. However, it rests with its protruding sections 29 on the support arm 36 of the attachment 35, so that it now relies on one of the two sheet metal portions 14, 20 in opposite directions, based on each other against opposite support arms 33 and 36.

Stransko vodenje poteka s prilagoditvijo oblike preseka prehodnega sredstva 25 in odprtin 26, 27, pri čemer se lahko ustrezno sl. 10 z v obliki ovratnika navzgor zapognjenimi pločevinastimi odseki 41 doseže še boljše stransko vodenje in zmožnost uvajanja. Vidi pa se tudi, da se lahko z ustrezno poševnino stranskih sten uvajanje še nadalje izboljšuje.The lateral guidance is made by adjusting the cross-sectional shape of the passage means 25 and the openings 26, 27, whereby the corresponding FIG. The collar-shaped section 10 with upwardly folded sheet sections 41 achieves even better lateral guidance and deployment capability. However, it can be seen that the introduction of the sloping side walls can further improve the introduction.

Pokrov in priključna pločevina sta medsebojno povezana s točkami 42 kovičenja. To so lahko običajne kovice ali pa iz enega materiala izštancani in za drugim zapognjeni jeziki, prednostno pa se uporablja tehnika povezave s kovicami, ki je poznana pod blagovno znamko ΤΟΧ. Pri tem se lahko s posebnim oblikovanjem matrice in patrice v oba drug prek drugega položena materiala oblikuje točka kovičenja, katere presek je prikazan v sl. 8. Tako nastaneta dve korespondirajoči, druga v drugo vstopajoči izboklini, ki se lahko s stranskim spajanjem materiala med seboj povežeta tudi oblikovno-sklepno.The cover and the connection plate are interconnected with the rivet points 42. These may be ordinary rivets or tongues extruded from one material and bent after the other, preferably using the riveting technique known under the trademark ΤΟΧ. In this case, by means of a special molding of the die and the die, a rivet point can be formed in both materials placed over each other, the cross section of which is shown in FIG. 8. In this way two corresponding, protuberant protuberances, which can be connected with the lateral joining of the material, can also be connected with the shape-joint.

V sl. 4 so razvidne tri takšne točke kovičenja, ki so nameščene na obeh straneh odprtin 26, 27 in imajo zaradi dobre učvrstitve veliko širino osnove. S povezavo pokrova in priključne pločevine se istočasno oblikovno-sklepno v obeh smereh pričvrsti tudi prehodno sredstvo 25.In FIG. 4 shows three such rivet points, which are located on both sides of the openings 26, 27 and have a large base width due to their good fixation. By connecting the cover and the connection plate, a transitional means 25 is attached at the same time to the joint in both directions.

Pri ustreznem oblikovanju, npr. z zamenjavo oblik luknje med pokrovom in priključno pločevino bi se lahko v ostalem na enak način izvajala tudi vgradnja prehodnega sredstva od spodaj. Tudi v ostalem bi bilo lahko prehodno sredstvo oblikovano različno. Pomembno je, da nastopata na njem dve področji z druga proti drugi nasprotno usmerjenimi opornimi rameni, pri čemer je možno vsakokrat v smeri vriskanja (smer središčne osi 43 prehodnega sredstva) vriskanje do naležnega ramena 33, 36.In proper design, e.g. by replacing the hole shapes between the lid and the connection plate, the installation of the transient means from below could be carried out in the same way. In the rest, the transitional means could be designed differently. It is important that there are two areas facing each other in opposite directions with the support arms, whereby it is possible each time in the direction of the scream (direction of the center axis 43 of the transient means) to scroll to the contact shoulder 33, 36.

Nadaljnja montaža je potem zelo preprosta. Iz pokrova 14, priključne pločevine 20 in od te obdanega in pričvrščenega prehodnega sredstva 25 sestoječa montažna enota se lahko dovaja električni kuhalni plošči kot celota in v danih pogojih natakne avtomatično prek takrat še pokončno stoječih priključnih vodnikov 23, ki se šele zatem zapognejo. Ta namestitev je primerna tudi čisto posebno za razporede, pri katerih štrijo priključni vodniki 23 samo malo iz prehodnega sredstva 25 in so tam povezani npr. z varjenjem s stransko potekajočimi priključnimi vodniki.Further installation is then very easy. From the cover 14, the connection plate 20, and from this enclosed and secured transition means 25, an existing mounting unit can be fed to the electric hob as a whole and automatically inserted under the conditions through the then upright connecting cables 23, which are then folded. This arrangement is also particularly suitable for schedules in which the connection conductors 23 are only slightly out of the passage means 25 and are connected there e.g. by welding with side-running connection wires.

Sl. 11 in 12 prikazujeta izvedbo, ki je v načelu in tudi v osnovni obliki enaka že opisani. Tam pa je povezava med pokrovom in priključno pločevino izvedena s pločevinastimi jeziki 44, ki sestojijo iz materiala, ki štrli v odprtino 27 in ki je preostal. Uporabi se lahko enaka oblika prehodnega sredstva 25. V področju med nastavki 32 in 35, v katerem ne obstajajo nobena podporna ramena, prehajata skozi skupaj vsakokrat dva pločevinasta jezika 44, pri čemer bi stala v montažnem stanju v sl. 11 navpično navzdol in bi se potem prekrivila v prikazano obliko. Tudi ta tehnika povezovanja ne potrebuje nobenih tujih materialov. Bilo bi tudi možno, da se predvidi jezike na pokrovu 14, tako da bi se potem v risbah prekrivili na gornjo stran.FIG. 11 and 12 show an embodiment which is in principle and in basic form identical to the one already described. There, however, the connection between the lid and the connection plate is made by sheet metal 44 consisting of a material projecting into the opening 27 and remaining. The same shape of the transitional means 25 may be used. In the area between the nozzles 32 and 35, in which no supporting arms exist, two sheet metal tongues 44 are passed through each at one time, with the mounting condition in FIG. 11 vertically downwards and would then overlap into the shape shown. Also, this stranding technique does not require any foreign materials. It would also be possible to anticipate the tongues on cover 14 so that they would then overlap in the drawings above.

Sl. 13 in 14 kažeta, da je pritrditev prehodnega sredstva po velikost spremenljiva. Pri prehodnem sredstvu 25a po sl. 14, ki ima samo dve prehodni luknji 30 in je temu ustrezno bistveno krajše, se lahko kljub temu uporablja prekrivno pločevino, ki je predvidena tudi za izvedbo s štirimi prehodnimi luknjami in ima temu ustrezno odprtino 26 po sl. 2. Pri v ostalem ustrezno krajšem oblikovanju je treba paziti samo na to, da je nastavek 35 tako širok, da so njegovi zunanji robniki 50 vodeni na zunanjih robnikih 51 izreza 28 v sl. 2. S tem je kljub bistveno manjši širini podano brezhibno vodenje prehodnega sredstva v odprtini 26. Prirobnica 32 nalega na površini. Priključna pločevina 20 ima izrez 27a (sl. 13), ki je po obliki in velikosti prilagojen prehodnemu sredstvu 25a po sl. 14. Dolžina nastavkov 29 tu nima nobene vloge, ker se pri natikanju priključne pločevine 20 izvede vodenje prek zunanjih robnikov prirobnice 32.FIG. 13 and 14 indicate that the attachment of the transition agent is variable in size. In the transition means 25a of FIG. 14, which has only two transition holes 30 and is substantially shorter, may, however, use an overlay sheet, which is also intended to be designed with four transition holes and has a corresponding opening 26 according to FIG. 2. In other suitably shorter designs, care should be taken only to ensure that the nozzle 35 is so wide that its outer edges 50 are guided at the outer edges 51 of the recess 28 in FIG. 2. In spite of the considerably smaller width, a smooth guiding of the transient means is provided in the opening 26. Flange 32 rests on the surface. The connecting plate 20 has a recess 27a (FIG. 13) adapted in shape and size to the transition means 25a of FIG. 14. The length of the attachments 29 does not play any role here, since the guide plate 20 is guided through the outer edges of the flange 32.

Vidi se torej, da je ta način pritrjevanja zelo variabilen in da omogoča vgradnjo kar najbolj različnih prehodnih sredstev v enako prekrivno pločevino. To zmanjšuje potrebno raznolikost tipov. Ni nujno, da prevzame vodenje v prekrivanju ali priključni pločevini zunanja oblika prehodnega sredstva, temveč se lahko poseže tudi po notranjih sredstvih vodenja, kot robnikih 50, 51. Priključna pločevina 20 po sl. 13 prekriva v tem primeru v pokrovu 14 večjo odprtino 26.Therefore, it can be seen that this method of fastening is very variable and that it allows the installation of as many different transitional means as possible in the same covering sheet. This reduces the required variety of types. It is not necessary to assume the control of the overlay or the connecting plate by the exterior of the transient means, but may also resort to internal means of control such as curbs 50, 51. The connecting plate 20 of FIG. 13, in this case, in the cover 14, a larger opening 26.

Claims
