Description
Elektrisk varmeanordning. Electric heating device.
Denne oppfinnelse angår elektriske opphetere, spesielt av den art hvor elektriske opphetningselementer er montert på glassplater. This invention relates to electric heaters, especially of the kind where electric heating elements are mounted on glass plates.
I en vanlig elektrisk oppheter, hvor det anvendes en glassopphetningsplate, In an ordinary electric heater, where a glass heating plate is used,
blir platen fastholdt i en omgivende ramme ved hjelp av atskilte klemelementer eller -ører, som er løsbart forbundet med rammen eller med den bak platen anbragte reflektor. Fjærer eller fjærende puter blir også anvendt sammen med klemelementene. Da det kreves verktøy for å feste eller the plate is held in a surrounding frame by means of separate clamping elements or lugs, which are releasably connected to the frame or to the reflector placed behind the plate. Springs or resilient cushions are also used in conjunction with the clamping elements. As tools are required to attach or
fjerne klemelementene er den vanlige praksis å forsende slike opphetere med glassplatene montert på plass, men dette er kostbart fordi fraktnoteringene er de som gjelder for glass, og disse er høyere enn de som gjelder for metall. Enn videre inntrer den ulempe at hvis en glassplate må utskiftes, eller at oppheteren er blitt tatt i bruk, er det ofte vanskelig for en vanlig husholder å foreta en slikt utskift-ning. remove the clamping elements, the usual practice is to ship such heaters with the glass plates fitted in place, but this is expensive because the shipping quotes are those for glass, and these are higher than those for metal. Furthermore, the disadvantage arises that if a glass plate has to be replaced, or if the heater has been put into use, it is often difficult for an ordinary householder to carry out such a replacement.
Blant oppfinnelsens formål er å skaffe Among the purposes of the invention is to provide
en elektrisk oppheter som ikke krever noe verktøy for montering av en glassheterplate i dennes ramme, eller for å fjerne platen fra rammen, og hvor atskilte festedeler for en plate av en hvilken som helst an electric heater requiring no tools for mounting a glass heater plate in its frame, or for removing the plate from the frame, and where separate attachment parts for a plate of any
ønsket lengde er unødvendige, og hvor oppheterplatene lett kan plasseres av nær sagt hvilken som helst person. the desired length is unnecessary, and where the heating plates can be easily placed by almost any person.
I henhold til oppfinnelsen har opp-heterrammen en bakvegg og en åpen front. Inne i rammen er det anbragt en konkav, rektangulær reflektor i form av en metall-plate, som vender mot rammens åpne front. Festedeler forbinder reflektorens midtre parti med bakveggen. Ovenfor og nedenfor festedelene er reflektoren buet fremover og har topp- og bunnkantpartier som er bøyet slik at de griper over topp-og bunnpartiene av en vertikal glassopp-heterplate. Reflektoren er tilstrekkelig fjærende til at minst en av dens kanter fjærer bort fra den annen kant, slik at en oppheterplate kan innføres mellom kan-tene resp. tas bort fra disse. På denne måte griper selve reflektoren platen og holder denne på plass. According to the invention, the heater frame has a rear wall and an open front. Inside the frame is a concave, rectangular reflector in the form of a metal plate, which faces the open front of the frame. Fixing parts connect the middle part of the reflector to the rear wall. Above and below the attachment parts, the reflector is curved forward and has top and bottom edge portions which are bent so as to grip over the top and bottom portions of a vertical glass heater plate. The reflector is sufficiently springy that at least one of its edges springs away from the other edge, so that a heating plate can be introduced between the edges or are taken away from these. In this way, the reflector itself grips the plate and holds it in place.
En foretrukken utførelsesform av oppfinnelsen er vist på den vedføyede tegning, hvor A preferred embodiment of the invention is shown in the attached drawing, where
fig. 1 er et frontoppriss av oppheteren, fig. 1 is a front elevation of the heater,
og and
fig. 2 viser et vertikalsnitt etter linjen fig. 2 shows a vertical section along the line
II—II i fig. 1. II—II in fig. 1.
Oppheterens ramme består av plate-metall og kan ha en hvilken som helst ønsket størrelse resp. lengde. Den kan monteres i eller på en vegg, og kan er-statte en del av eller hele veggplaten. Fortrinnsvis er rammen dannet av minst tre deler, nemlig en toppseksjon 1 og en bunn-seksjon 2, som er forbundet med hverandre ved en midtre vertikal plate 3. Bunnseksjonen er fremstilt av en metallstrimmel som er ombøyd slik at den danner en bunn 4, en bakvegg 5, en frontflens 6, samt en skrå innervegg eller skillevegg 7 som tjener som et slags klammer. Rommet mellom bakveggen og skilleveggen kan nyttes som kanal for gjennomføring av de elektriske ledninger 8. Den øvre seksjon 1 er utformet på stort sett samme måte som bunnseksjonen. Disse to seksjoner er anordnet i avstand fra hverandre vertikalt, The heater's frame consists of sheet metal and can have any desired size or length. It can be mounted in or on a wall, and can replace part or all of the wall plate. Preferably, the frame is formed of at least three parts, namely a top section 1 and a bottom section 2, which are connected to each other by a middle vertical plate 3. The bottom section is made of a metal strip bent so as to form a bottom 4, a rear wall 5, a front flange 6, as well as an inclined inner wall or partition 7 which serves as a kind of clamp. The space between the rear wall and the partition wall can be used as a channel for the passage of the electrical cables 8. The upper section 1 is designed in largely the same way as the bottom section. These two sections are arranged at a distance from each other vertically,

As the plate is supported continuously throughout its length, heaters of any length can be used, which makes the present invention particularly important in connection with air-ice heaters. A further advantage is that the glass plate can be produced
