Description

'fßüöwé-fe 10 15 20 25 30 35 2 memediet, ärti linje med husdelen, uppnås en stor värme- överföring från värmemediumkanalerna till livet och därifrån till rummet, som skall uppvärmas, så att en hög verkningsgrad erhålles. In the line with the housing part, a large heat transfer is achieved from the heating medium channels to the life and from there to the room, which is to be heated, so that a high efficiency is obtained.

En ytterligare fördel är att man utan svårighet och utan större omkostnader kan anbringa en elektrisk värmekropp i en värmeapparat, som för övrigt är anordnad för användning av ett äng- eller vätskeformat medium, så att effekten av fotpanelsvärmeapparaten kan ökas på speciellt utsatta ställen, exempelvis under ett fönster, och det kan också vara fördelaktigt att under vissa årstider nöja sig med elektrisk uppvärmning under vissa tider av dygnet- Enligt en speciell utföringsform av uppfinningen är det angivna huset utformat med organ för montering av åtminstone ett uttag för anslutning av kablarna till en plugg på en ledning som sträcker sig till en förbruk- ningsenhet.A further advantage is that an electric heater can be fitted without difficulty and without major costs in a heating apparatus, which is otherwise arranged for use of a meadow or liquid-shaped medium, so that the effect of the foot panel heater can be increased in particularly exposed places, for example under a window, and it may also be advantageous in certain seasons to be satisfied with electric heating during certain times of the day. According to a special embodiment of the invention, the indicated housing is formed with means for mounting at least one socket for connecting the cables to a plug. on a line that extends to a consumption unit.

Genom utformningen kan värmeapparaten utan speciel- la omkostnader anordnas att bilda skärm för elektriska starkströms- eller svagströmskablar till rummets försörj- ning med ström, exempelvis till lampor, hushållsappara- ter eller televisionsapparater.Due to the design, the heater can be arranged without special overheads to form a screen for electrical high-current or low-current cables for the room's supply of power, for example for lamps, household appliances or television sets.

Uppfinningen beskrivs närmare i det följande med hänvisning till de bifogade ritningarna, som visar före- dragna utföringsformer. Fig l visar en del av en husdel sedd i perspektiv och i tvärsektion. Fig 2 är en sektion genom en utföringsform av en värmeapparat enligt uppfin- ningen monterad på en rumsvägg. Fig 3 är en andra utfö- ringsform av en värmeapparat enligt uppfinningen sedd från sidan. Fig 4 är en sektion genom värmeapparaten i fig 3 fastgjord på en rumsvägg. Fig 5 är en vy liknande den i fig 3 av ännu en utföringsform av värmeapparaten.The invention is described in more detail below with reference to the accompanying drawings, which show preferred embodiments. Fig. 1 shows a part of a housing part seen in perspective and in cross section. Fig. 2 is a section through an embodiment of a heating apparatus according to the invention mounted on a room wall. Fig. 3 is a second embodiment of a heater according to the invention seen from the side. Fig. 4 is a section through the heater of Fig. 3 attached to a room wall. Fig. 5 is a view similar to that of Fig. 3 of yet another embodiment of the heater.

Fig 6 är en sektion genom apparaten i fig 5 fastgjord på en rumsvägg.Fig. 6 is a section through the apparatus of Fig. 5 attached to a room wall.

En värmeapparat enligt uppfinningen har, såsom vi- sas i fig 4, en första husdel k, som är framställd i ett _ ...u vaoezos-4 3 stycke, företrädesvis genom strängsprutning av en lämp- lig metallegering. Den första hnsdelen 1 har ett lodrätt liv 2, på vilket två längsgående vulster 3 är utformade, vilkas hàlrum 4 bildar längsgående kanaler.A heater according to the invention has, as shown in Fig. 4, a first housing part k, which is made in one piece, preferably by extruding a suitable metal alloy. The first hand part 1 has a vertical web 2, on which two longitudinal beads 3 are formed, the cavities 4 of which form longitudinal channels.

Den första husdelen l uppbära av en andra husdel 5, som har ett lodrätt, med hjälp av skruvar 8 på en rums- vägg ? fastgjort liv 6 och som har bockade flänsar 9, vilka genom snäppverkan kan ingripa med de bort från varandra vända, krökta ovanytorna av vulsterna 3.The first housing part 1 supported by a second housing part 5, which has a vertical, by means of screws 8 on a room wall? attached web 6 and which has bent flanges 9, which by snap action can engage with the curved upper surfaces of the beads 3 facing away from each other.

Husdelen l har vidare en övre fläns 10, som sträcker sig mot rumsväggen 3, samt en nedre fläns ll, vilken har en vinkelformad tvärsektion och anligger mot golvet 12 i rummet.The housing part 1 further has an upper flange 10, which extends towards the room wall 3, and a lower flange 11, which has an angular cross-section and abuts against the floor 12 in the room.

I fig l visas husdelen l dels i perspektiv, dels i sektion. Samtidigt med strängsprutningen av husdelen l frambringas upptill två och nedtill ett längsgående spår 13, i vilka efter strängsprutningen rader av hål upptages, som tjänar till att åstadkomma en viss luftcirkulation genom husdelen och förbi de tvâ vulsterna 3.Fig. 1 shows the housing part 1 partly in perspective and partly in section. Simultaneously with the extrusion of the housing part 1, a longitudinal groove 13 is produced at the top two and at the bottom, in which after the extrusion rows of holes are accommodated, which serve to provide a certain air circulation through the housing part and past the two beads 3.

Utföringsformen i fig 1 är anordnad för uppvärmning med hjälp av ett äng- eller vätskeformat värmemedium eller möjligtvis ett liknande kylmedium, och fotpanelen är tänkt att sammansättas av sektioner av profilskenor av det i fig l visade slaget med hjälp av passande rörkopplingar, som kan förbinda kanalerna 4 i de mot varandra anliggande sektionerna med varandra.The embodiment in Fig. 1 is arranged for heating by means of a meadow or liquid-shaped heating medium or possibly a similar cooling medium, and the foot panel is intended to be composed of sections of profile rails of the type shown in Fig. 1 by means of suitable pipe couplings which can connect the channels. 4 in the abutting sections with each other.

Vid utföringsformen i fig 3 och 4 är husdelen l ut- formad med två längsgående spår 14 på de mot varandra vända sidorna av vulsterna 3, och i dessa spår mottages flikar 15 på en profilskena 16 med stegformad tvärsektion, varvid fyra avdelningar 17 bildas för elektriska kablar 18, av vilka några kan vara förbundna med uttagsdosor 19 på den utvändiga sidan av livet 2. Kablarna l8, vilka kan vara förbundna med belysníngsnätet eller en tillförselkälla för svagström, tjänar till att leverera ström till hus- hållsutrustning, såsom lampor, elektriska apparater, tele- ?$062@6~ ål un 10 15 20 4 visionsapparater etc, och husdelen l tjänstgör således som bärorgan och skärm för dessa elektriska ledningar samt bär- organ för uttaget 19 och strömställare för strömmen. vid utföringsformen i fig 6 användes spåren lå för att mottaga en skivformad, elektrisk värmekropp 20, vilken 5åS0m framgår av fig 5 förlöper i sicksack genom husets längd- rlktnlng och vilken tjänar till att utfylla eller ersätta värmeeffekten från värmemediumkanalerna 4. På värmekroppen finns ett förbindningsorgan 21, som är anordnat att för- binda värmekroppar hos tvâ mot varandra anliggande apparat- sektioner med varandra, Utföringsformen i fig 2 är anordnad för uppvärmning dels genom ett äng- eller vätskeformat värmemedium i kanalerna 4, dels genom en elektrisk värmekropp 20, som uppbäres av husdelen l på samma sätt som visas i fig 6.In the embodiment in Figs. 3 and 4, the housing part 1 is formed with two longitudinal grooves 14 on the facing sides of the beads 3, and in these grooves tabs 15 are received on a profile rail 16 with a stepped cross-section, four compartments 17 being formed for electrical cables 18, some of which may be connected to sockets 19 on the outside of the web 2. Cables 18, which may be connected to the mains or a low-power supply, serve to supply power to household equipment, such as lamps, electrical appliances , tele-? $ 062 @ 6 ~ ål un 10 15 20 4 vision devices etc, and the housing part 1 thus serves as a support means and shield for these electrical wires as well as support means for the socket 19 and switches for the current. in the embodiment of Fig. 6, the grooves were used to receive a disc-shaped, electric heating element 20, which 5 as shown in Fig. 5 zigzags through the longitudinal direction of the housing and which serves to fill or replace the heating effect from the heating medium channels 4. On the heating body there is a connecting means 21, which is arranged to connect heating bodies of two abutting apparatus sections to each other. The embodiment in Fig. 2 is arranged for heating partly through a meadow or liquid-shaped heating medium in the channels 4, partly through an electric heating body 20, which is supported of the housing part 1 in the same way as shown in Fig. 6.

Dessutom är apparaten anordnad att innehålla elektriska kablar 18 på samma sätt som vid utföringsformen i fig 4, och kablarna uppbäres av en profilskena 22 med stegformad tvärsektion, vars ändflikar ingriper med de mot varandra vända ovanytorna av vulsterna 3.In addition, the apparatus is arranged to contain electrical cables 18 in the same way as in the embodiment in Fig. 4, and the cables are supported by a profile rail 22 with a stepped cross section, the end flaps of which engage with the facing upper surfaces of the beads 3.
