(54) Elektrisk radiator.(54) Electric radiator.

Opfindelsen angår en elektrisk radiator af den art, som er indrettet til at danne fodpanel i det rum, den skal opvarme, og som har et aflangt, fladt, kasseformet hus af metalplade, der består af to halvparter, som har forbindelsesorganer til snapindgreb med hinanden, og øvre og nedre bæreorganer for et elektrisk varmelegeme, der i en siksak-linie strækker sig fra radiatorens ene ende til den anden.BACKGROUND OF THE INVENTION The present invention relates to an electric radiator of the kind adapted to form a foot panel in the space to be heated, which has an elongated, flat, box-shaped metal plate housing consisting of two half-pieces having snap engagement connectors and upper and lower supports for an electric heater extending in a zigzag line from one end of the radiator to the other.

O En elektrisk radiator af denne art vil være tilbøjelig til at af- Ξ give en vis støj, der i det lange løb kan være højst generende for ~ de personer, der skal opholde sig i det af radiatoren opvarmede :$· -j. rum. Denne støj skyldes den ved opvarmning og afkøling af varme- t 3 2 144110 legemet frembragte bevægelse af metaldelene, og såfremt det drejer sig om en radiator, der strækker sig over en væsentlig længde, f.eks. en stor del af rummets vægge, vil selv en svag støj pr. længdeenhed af apparatet kunne danne en samlet sum, der kan virke generende.O An electric radiator of this kind will tend to give Ξ some noise which in the long run can be extremely troublesome for ~ the persons who must stay in the heater heated: $ · -j. room. This noise is caused by the movement of the metal parts by heating and cooling the body, and in the case of a radiator extending over a considerable length, e.g. a large part of the walls of the room, even a slight noise per night will. length unit of the apparatus could form a total sum that may seem bothersome.

En væsentlig støjkilde er, at husets to halvparter sædvanligvis fremstilles af forskellige materialer, idet bagparten som oftest fremstilles af galvaniseret stål, medens forparten fremstilles af lakeret stål, og de to materialer vil antage forskellige temperaturer, fordi deres evne til varmeabsorption og reflektion er forskellig, og den af varmelegemet fremkaldte strålevarme vil derfor ved tænding og slukning medføre forskellig varmeudvidelse og sammentrækning i de to halvparter. Såfremt halvparterne er forbundet med hinanden på en sådan måde, at de omtalte kræfter ikke kan fremkalde indbyrdes bevægelser i radiatorens plan, vil der fremkomme spændinger og derved tendenser til buledannelse med deraf følgende knitrende lyde.A major source of noise is that the two halves of the housing are usually made of different materials, the rear most often being made of galvanized steel, while the front part is made of lacquered steel, and the two materials will assume different temperatures because their ability to heat absorption and reflect is different. and the radiant heat generated by the heater will therefore cause different heat expansion and contraction in the two halves upon switching on and off. If the halves are interconnected in such a way that the said forces cannot induce mutual movement in the plane of the radiator, then tensions and consequent tendencies of bulging will arise with the resulting crackling sounds.

Tilsvarende støj kan frembringes, hvis radiatorens bagvæg er spændt tæt op imod rumvæggen, således at forskydning er forhindret.Similar noise can be produced if the rear wall of the radiator is clamped tightly up against the room wall so that displacement is prevented.

En tredie støjkilde er selve varmelegemet, der som oftest er fremstillet af en tråd, der er viklet i skruelinieform og anbragt efter en siksak-linie. Ved udvidelse og sammentrækning kan der frembringes en svag klingende lyd.A third source of noise is the heater itself, which is usually made of a thread wound in helical form and arranged along a zigzag line. By expansion and contraction, a faint sounding sound can be produced.

Det er formålet med opfindelsen at tilvejebringe en radiator af den angivne art, som er således indrettet, at den omtalte støj elimineres, således at radiatoren kan anvendes som et langt panel i et opholdsrum og styres termostatisk med deraf følgende mange strømstarter og strømafbrydelser uden støjgener for de i rummet værende personer. Dette opnås ved, at husets to halvparter har parallelle og i konstant afstand fra hinanden værende, plane pladedele, som kun er forbundet med hinanden ved hjælp af mod hinanden vendende øvre og nedre flanger, som er udformet til at snapindgribe således med hinanden,at pladedelene kan forskydes i forhold til hinanden i radiatorens længderetning, at de elektriske varmelegemer består af bøjelig modstandstråd, som er indlejret i en glasfiberkappe og er op 3 144110 hængt i øskenagtige organer på den ene halvpart, hvis plane pladedel danner radiatorens bagvæg, og at der på radiatorens bagvæg findes navorganer for fastgørelsesskruer til ophængning af radiatoren på en væg.SUMMARY OF THE INVENTION It is an object of the invention to provide a radiator of the kind specified so as to eliminate said noise so that the radiator can be used as a long panel in a living room and is thermostatically controlled with the resultant many power starts and interruptions without noise nuisance. the people in the room. This is achieved by having the two halves of the housing have parallel and at a constant distance from each other, flat plate parts, which are connected only to each other by means of facing upper and lower flanges, which are designed to snap-engage so that the plate parts can be displaced relative to one another in the longitudinal direction of the radiator, that the electric heaters consist of flexible resistance wire embedded in a fiberglass sheath and hung up in desirable bodies on one half, the flat plate part of which forms the rear wall of the radiator, and that on the rear wall of the radiator there are additional means for fastening screws for hanging the radiator on a wall.

Ved denne udformning af radiatoren vil husets to halvparter, efter at de er forbundet med hinanden ved snapindgreb mellem flangerne, kunne glide i radiatorens længderetning i forhold til hinanden, således at der ikke opstår spændinger i materialet eller støj, når halvparterne udvider sig forskelligt under opvarmning. Den fra det elektriske varmelgeme stammende støj fjernes ved, at varmelegemets tråde er indlejret i glasfiber, således at svingninger, der kan medføre klingende lyde, undgås. Endelig afhjælper navorganerne i forbindelse med fastgørelsesskruerne den fra radiatorens montering hidrørende støj, idet navorganerne for det første holder radiatorens bagvæg i afstand fra rumvæggen og endvidere på en sådan måde, at små bevægelser i retninger paralelle med bagvæggens plan muliggøres, specielt når skruediameteren er lidt mindre end navets lysningsdiameter.In this design of the radiator, the two halves of the housing, after being connected to each other by snap engagement between the flanges, will be able to slide in the longitudinal direction of the radiator relative to each other, so that no tension in the material or noise arises when the halves expand differently during heating. . The noise emanating from the electric heater is removed by the wires of the heater being embedded in fiberglass so as to avoid oscillations which may cause sounding sounds. Finally, the secondary means associated with the fastening screws remedies the noise emitted by the radiator mounting, the first means keeping the rear wall of the radiator away from the room wall and furthermore in such a way that small movements in directions parallel to the rear wall plane are possible, especially when the screw diameter is slightly smaller. than the hub diameter of the hub.

Den omstændighed, at modstandstråden kun er i forbindelse med radiatorens ene halvpart og den anden halvpart blot er en simpel plan plade, medvirker også til at dæmpe støj hidrørende fra varmeudvi-delser.The fact that the resistance wire is only in connection with one half of the radiator and the other half is merely a simple flat plate also contributes to dampening noise resulting from heat expansions.

I det følgende forklares opfindelsen under henvisning til tegningen, hvor fig. 1 viser en del af et radiatorhus set i perspektiv delvis i snit, fig. 2 en radiator udformet som fodpanel set i perspektiv og fig. 3 et snit efter linien III-III i fig. 1 i større målestok.In the following, the invention is explained with reference to the drawing, in which 1 is a partial perspective view of a part of a radiator housing; FIG. 2 is a perspective view of a radiator formed as a foot panel; and FIG. 3 is a sectional view taken along line III-III of FIG. 1 on a larger scale.

nadiatoren, som ifølge fig. 2 virker som fodpanel i en stue, er fremstillet af sektioner, der hver består af en indre skinne 1, der har en plan central del 2 og to kantflanger 3, som står vinkelret på den centrale del 2, samt en ydre skinne k, der også har en central del 5, og to vinkelret derpå stående kantflanger 6.the nadiator, which according to FIG. 2 acts as a foot panel in a living room, made up of sections, each consisting of an inner rail 1 having a planar central portion 2 and two edge flanges 3 perpendicular to the central portion 2, as well as an outer rail k which also has a central portion 5 and two perpendicular flanges 6 perpendicular thereto.

De to skinner er samlet således som det fremgår af fig. 1 og 3, 144110 4 hvor flangerne 6 griber ind over flangerne 3 og med en nedadgående flig 7 fastholdes ved snapvirkning. Skinnerne 1 og 4 er fortrinsvis fremstillede af bukket metalplade.I den centrale del 5 findes der foroven og forneden luftcirkulationshuller 8.The two rails are assembled as shown in FIG. 1 and 3, where the flanges 6 engage over the flanges 3 and with a downward flap 7 are retained by snap action. The rails 1 and 4 are preferably made of bent metal sheet. In the central part 5 there are upper and lower air circulation holes 8.

På flangerne 3 for den indre skinne 1 er der fastgjort nogle bærekonsoller 9, som bærer nogle rørstykker 10,fortrinsvis af isolerende materiale, f.eks. keramik eller formstof. Gennem rørstykkerne 10 er der ført et trådformet varmelegeme 11, som består af en elektrisk modstandstråd, der eventuelt kan være dannet som en skruelinie, og som er omsluttet af en kappe af isolerende materiale, f.eks. et glasmateriale, som er bøjeligt og i hovedsagen ustrækbart.On the flanges 3 of the inner rail 1 are attached some support brackets 9 which carry some pipe pieces 10, preferably of insulating material, e.g. ceramic or plastic. Through the pipe pieces 10 is passed a wire-shaped heater 11, which consists of an electrical resistance wire, which may be formed as a helical line, and which is enclosed by a sheath of insulating material, e.g. a glass material which is flexible and substantially non-stretchable.

Som det fremgår af fig. 1, kan tråden 11 være anbragt i zig-zag udefter det af skinnerne 1 og 4 dannede hus, men tråden kan være anbragt på enhver ønsket måde, f.eks. som en kombination af sektioner, der strækker sig parallelt med flangerne 3,og sektioner, der strækker sig vinkelret på disse, eller tråden kan være ført alene i husets længderetning. Tråden kan være ophængt på ethvert passende bæreorgan, som er øskenagtigt eller krogagtigt, således at det kan holde tråden i stilling.As shown in FIG. 1, the wire 11 may be arranged in zig-zag along the housing formed by the rails 1 and 4, but the wire may be arranged in any desired manner, e.g. as a combination of sections extending parallel to the flanges 3 and sections extending perpendicular thereto, or the thread may be guided alone in the longitudinal direction of the housing. The thread may be suspended from any suitable carrier which is oily or hook-like, so that it can hold the thread in position.

På den centrale del 2 af den indre skinne 1 er der fastgjort navorganer 12 for fastgørelsesskruer 13, ved hjælp af hvilke den indre skinne 1 kan fastgøres direkte på en væg 14 som vist på fig. 3. Den ydre skinne 4 fastholdes som nævnt ved snapvirkning, men hvis det forlanges kan der let anbringes skruer, der forbinder de to skinner med hinanden.On the central portion 2 of the inner rail 1, secondary members 12 for fastening screws 13 are secured by means of which the inner rail 1 can be fixed directly to a wall 14 as shown in FIG. 3. The outer rail 4 is retained as mentioned by snap action, but if required screws can easily be attached connecting the two rails to each other.

Under den nedre flange 6 er der anbragt en tætningsliste 15, som udfylder rummet imellem radiatoren og gulvet 16 i det opvarmede rum, og som kan være af et forholdsvis elastisk formstof.Underneath the lower flange 6 is a sealing strip 15 which fills the space between the radiator and the floor 16 in the heated space and which may be of a relatively elastic resin.

Som nævnt kan et gulvpanel 17 opbygges af sektioner af huse dannet af skinner 1 og 4, og på fig. 1 er med punkterede linier vist en del af en sektion, som er samlet med den med fuld streg viste sektion, hvilket kan ske ved indskydning af skinnerne i hinanden eller eventuelt ved hjælp af en art forbindelsesmuffe. Ved hjælpAs mentioned, a floor panel 17 can be constructed of sections of houses formed by rails 1 and 4, and in FIG. 1 is a fragmentary sectional view of a section which is assembled with the section shown in full line, which can be accomplished by sliding the rails into each other or possibly by means of a kind of connecting sleeve. Through

Claims

5 mm of junction boxes 18, the resistance wires of the various sections can be easily connected to each other so that the sections are electrically connected in series. As shown by arrows in FIG. 1 and 3, through holes 8 there will be provided an upward flow of air, which is promoted by the chimney effect of the narrow housing, and which substantially increases heat release by convection. A particular advantage of a radiator according to the invention and of the nature described is that it will often be appropriate to use a radiator housing which contains a heating element for a limited part of its length. This will be particularly advantageous, since the radiator is designed as a foot panel, in which case the radiator can extend along all the walls of the room, while only heating elements corresponding to the heating demand are placed. The heat will propagate through the housing, especially the front rail 4, from the gones where there are heaters to the zones without heaters, thereby lowering the temperature of the radiator, thus improving the economy and providing a comfortable heat distribution in the room. The inner rail 1 may be divided into sections, partly provided with heaters and partly not, while the outer rail 4 may be continuous from one corner of the room to the other, thus covering several sections of the inner rail 1. If If the outer rail is made of aluminum or an aluminum alloy, a good heat-conducting connection can be obtained between the parts of the radiator provided with heaters and the other parts. Claims.
