Den foreliggende opfindelse angår et køleskab med kondensator og af den art, hvor en væsentlig del af kondensatoren er udformet som en rørslange, hvor rørslangen er anbragt indvendigt i god varmel edende forbindelse med skabets svøb ved køleskabets bagside.The present invention relates to a refrigerator with a capacitor and of the kind in which a substantial part of the capacitor is designed as a pipe hose, the pipe hose being arranged internally in good heat-sealing connection with the enclosure of the cabinet at the rear of the refrigerator.

Der kendes køleskabe af denne art, hvor køleskabets bagside er plan. Sådanne køleskabe opstilles med en bestemt minimumsafstand fra den væg, op ad hvilken køleskabet anbringes, nemlig således at der bag køleskabet tilvejebringes en luftgennemstrømningspassage med tilstræk-10 keligt gennemstrømningsareal til, at den gennemstrømmende luft kan fjerne den fornødne del af den af kondensatoren udviklede varme. Da det såkaldte "indbygningsmål" som regel er standardiseret, d.v.s. at køleskabets forside ikke bør befinde sig længere fra den væg, ved hvilken køleskabet er opstillet, end en forudbestemt afstand, indebærer 15 overholdelsen af minimumsafstanden mellem skabets bagside og væggen en begrænsning, hvad angår køleskabets nyttevolumen.Fridges of this kind are known where the back of the refrigerator is flat. Such refrigerators are arranged at a certain minimum distance from the wall up to which the refrigerator is placed, such that an air flow passage with sufficient flow area is provided behind the refrigerator to allow the flowing air to remove the required part of the heat generated by the condenser. Since the so-called "built-in target" is usually standardized, i.e. that the front of the refrigerator should not be further from the wall at which the refrigerator is placed than a predetermined distance, compliance with the minimum distance between the back of the cabinet and the wall implies a restriction on the utility volume of the refrigerator.

Køleskabet ifølge den foreliggende opfindelse er ejendommeligt ved, at køleskabets bagside er udformet med en tilnærmelsesvis plan del og med 20 til begge sider for denne forløbende bagsidedele, der befinder sig nærmere skabets forside end den plane del. Beregninger, som ligger til grund for den foreliggende opfindelse, har vist, at et skab, der er udformet som angivet, kan anbringes med den plane del umiddelbart ved væggen, idet de sidekanaler, som tilvejebringes mellem den pågældende 25 væg og det opstillede skabs bagsidedele, giver den fornødne luftcirkulation, og muligheden for at anbringe køleskabets plane bagsidedel umiddelbart ved væggen medfører samtidig, at skabets nyttevolumen kan forøges.The refrigerator of the present invention is characterized in that the rear of the refrigerator is formed with an approximately planar portion and 20 on both sides for this extending rear side portion which is closer to the front of the cabinet than the planar portion. Calculations which form the basis of the present invention have shown that a cabinet designed as indicated can be placed with the planar portion immediately adjacent to the wall, the side channels provided between the respective wall and the rear of the set cabinet , provides the necessary air circulation, and the possibility of placing the refrigerator's flat back part immediately at the wall simultaneously increases the utility volume of the cabinet.

30 En særlig simpel udførelsesform for skabet ifølge opfindelsen er ejendommelig ved, at den plane del udgøres af en lodret midterdel af bagsiden og af de til siden for den plane midterdel forløbende bagsidedele udgøres af plane sidedele, der danner ens mod skabets forside åbne, stumpe vinkler med den plane midterdel, 35A particularly simple embodiment of the cabinet according to the invention is characterized in that the planar part is made up of a vertical center part of the back and of the rear side parts which extend to the side of the planar part are made of flat side parts which form equal to open, obtuse angles to the front of the cabinet. with the plane center portion, 35

Ifølge opfindelsen kan den stumpe vinkel ligge mellen ca. 130-165' fortrinsvis mellem ca. 140-160' og er hensigtsmæssigt ca. 150*.According to the invention, the blunt angle may be between about 130-165 'preferably between ca. 140-160 'and is suitably approx. 150 *.

Ifølge en yderligere udførelsesform for opfindelsen kan i det mindsteAccording to a further embodiment of the invention, at least

2 de til begge sider for den plane del forløbende bagsidedele være udformet af materiale, der pr. areal enhed har stor varmefylde. Herved opnås det, at de nævnte bagsidedele er i stand til at virke som varme-akkumulatorer, idet de ved start af køleskabet vil kunne optage en del 5 af kondensatorvarmen, og de vil, efter at skabet er stoppet, kunne afgive den akkumulerede varme, hvorved den tid, som varmeafgivelsen varer, kan forøges ud over den periode, hvori kompressoren arbejder, hvorved kondensatorkapaciteten forøges.2, the rear portions extending to both sides of the planar portion are formed of material which is per unitary. area unit has high heat density. Hereby it is obtained that the said rear parts are capable of acting as heat accumulators, in that, upon starting the refrigerator, they will be able to absorb part 5 of the condenser heat and, after the cabinet has been stopped, will be able to supply the accumulated heat. whereby the time that the heat release lasts can be increased beyond the period in which the compressor operates, thereby increasing the capacitor capacity.

10 Til opnåelse af den store varmefylde kan bagsidedelene ifølge opfindelsen være udformet af forholdsvis tykt metalplademateriale. Som eksempel på sådant materiale kan nævnes stål plade med en tykkelse på ca.To achieve the high thermal density, the backing parts of the invention may be formed of relatively thick metal sheet material. An example of such material is steel plate having a thickness of approx.

Ifølge opfindelsen kan kondensatoren være udformet som en rørslange med i lodret retning forløbende bugter.According to the invention, the capacitor can be designed as a pipe hose with bends extending vertically.

For at opnå en forøget kondensatorvarmeafgivelse langs sidedelene kan 20 kondensatorens rørstrenge være anbragt tættere ved siden af hinanden ved de til siden for den plane del forløbende bagsidedele end ved den plane del.In order to achieve increased capacitor heat release along the side portions, the capacitor tubing strings may be positioned closer to one another at the lateral portion of the planar portion than at the planar portion.

Ifølge opfindelsen kan den samlede bredde af sidedelene udgøre ca.According to the invention, the total width of the side portions may be approx.

25 20-50% hensigtsmæssigt mellem ca. 25-35% og fortrinsvis ca. 28% af skabets samlede bredde.20 to 50% conveniently between approx. 25-35% and preferably approx. 28% of the total width of the cabinet.

Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor 30 fig. 1 viser en udførelsesform for køleskabet ifølge opfindelsen set bagfra, fig. 2 det i fig. 1 viste køleskab set fra oven, fig. 3 det i fig. 1 viste køleskab set fra venstre, 35 fig. 4 det i fig. 1 viste køleskab vist perspektivisk, og fig. 5 et vandret snit gennem køleskabet svarende til den i fig. 2 viste cirkel A.The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 is a rear view of an embodiment of the refrigerator according to the invention; FIG. 2 shows the embodiment of FIG. 1 is a top view of the refrigerator; FIG. 3 shows the embodiment of FIG. 1, seen from the left, FIG. 4 shows the embodiment of FIG. 1 is a perspective view of the refrigerator, and FIG. 5 is a horizontal section through the refrigerator similar to that of FIG. 2, circle A.

3 Køleskabet har plane sidevægge 3,4, og dets bagside er betegnet med 5.3 The refrigerator has flat side walls 3,4 and its rear side is marked with 5.

Denne har en plan del 6, og til begge sider for denne forløber der bagsidedele 7,8, der befinder sig nærmere skabets fordør 2 end bagsidedelen 6, idet sidedelene 7,8 strækker sig under en stump vinkel i 5 forhold til den plane del 6. Denne vinkel er ved den på tegningen viste udførelsesform ca. 150" men kan ligge mellem ca. 130-165* og fortrinsvis mellem ca. 140-160*.This one has a flat part 6, and on both sides of this one there are rear side parts 7,8 which are closer to the front door 2 of the cabinet than the rear side part 6, the side parts 7,8 extending at a blunt angle in relation to the flat part 6 This angle, in the embodiment shown in the drawing, is approx. But may be between about 130-165 * and preferably between about 140-160 *.

Ved den på tegningen viste udførelsesform udgør sidedelenes bredde to-10 talt ca. 30% af skabets totale bredde, men sidedelenes bredde kan variere mellem ca. 20-50% fortrinsvis mellem ca. 25-35% af den totale bredde.In the embodiment shown in the drawing, the width of the side parts is approximately two. 30% of the total width of the cabinet, but the width of the side parts can vary between approx. 20-50% preferably between about 25-35% of the total width.

Skabet er forsynet med et køleaggregat, der i det viste tilfælde udgø-15 res af en kompressor 10, hvortil der hører en kondensator 11, Denne udgøres af en rørslange med lodret forløbende rørstrenge således som vist skematisk med punkteret linie i fig. 1. Ved den på tegningen viste udførelsesform findes der som vist i fig. 2 fem kondensatorrørstren-ge ved den plane del 6, en streng ved overgangen til hver af sidedele-20 ne 7,8, en streng ved hver af sidedelene 7,8, en streng ved bagkanten af hver sidevæg 3,4 og en streng ved hver af disse bagkanter. Som det fremgår af fig. 5 er rørkondensatoren 11 anbragt indvendigt i forhold til skabets svøb eller yderbeklædning 14 og står i god varmeoverførende forbindelse med denne, idet rørslangen er fastklæbet ved hjælp af 25 en godt varmel edende, klæbende masse 15.The cabinet is provided with a cooling unit, which in the illustrated case is comprised of a compressor 10, to which a capacitor 11 is attached. This consists of a pipe hose with vertically extending pipe strings as shown schematically in dotted line in FIG. 1. In the embodiment shown in the drawing, as shown in FIG. 2 are five capacitor tube strings at the plane portion 6, one strand at the transition to each of the side portions 7.8, one strand at each of the side portions 7.8, one strand at the trailing edge of each side wall 3,4, and one strand at each of these trailing edges. As shown in FIG. 5, the tube capacitor 11 is disposed internally with respect to the enclosure or outer casing 14 and is in good heat-transferring relationship therewith, the tube hose being adhered by means of a well-heat-sealing adhesive mass 15.

Som det fremgår af fig. 5 består sidedelen 8 af plademateriale, der i det viste tilfælde udgøres af en 2 mm tyk stål plade. Den anden sidedel 7 er udformet på tilsvarende måde. Skabets svøb 14 består iøvrigt af 30 stål plademateriale med en tykkelse på ca. 0,6 mm.As shown in FIG. 5, the side part 8 consists of sheet material, which in the illustrated case is constituted by a 2 mm thick steel sheet. The second side portion 7 is formed in a similar manner. The enclosure 14 also consists of 30 steel sheet material with a thickness of approx. 0.6 mm.

Pladedelene 7,8 er forbundet med de hosværende pladekanter f.eks. ved svejsning eller på anden måde, som giver en tæt forbindelse. Skabet er iøvrigt forsynet med en ikke-vist isolering, som støder op mod inder-35 siden af yderbeklædningen.The plate parts 7,8 are connected to the present plate edges e.g. by welding or otherwise which provides a close connection. Incidentally, the cabinet is provided with a non-visible insulation which abuts the inner side of the outer covering.

Den plane del 6 er foroven forbundet med en skrå oversidedel 16, og oversiden af skabet udgøres iøvrigt af en plan topdel 17. Forneden går den plane del 6 over i en skrå bagvægsdel 18, der ender i et loft 19The flat part 6 is connected at the top to a sloping top part 16, and the top of the cabinet is otherwise formed by a flat top part 17. Below, the flat part 6 goes into a sloping rear wall part 18 which ends in a ceiling 19

4 til en niche 20, hvori kompressoren 10 er anbragt.4 to a niche 20 in which compressor 10 is disposed.

Det viste skabs virkemåde er som følger: 5 Skabet opstilles med den plane bagsidedel 6 tæt ved en væg, der er antydet ved hjælp af en linie 21 i fig. 2. Derved fremkommer der i tværsnit kileformede kanaldele 22,23 mellem bagsidedelene 7,8 og væggen 21. Såfremt køleskabet anbringes f.eks. i et køkken, kan disse kanaldele 22,23 udadtil godt være begrænset af ved siden af skabet 10 værende køkkenmøbler.The operation of the cabinet shown is as follows: 5 The cabinet is positioned with the flat back side 6 close to a wall indicated by a line 21 in FIG. 2. Thus, in cross-section, wedge-shaped duct portions 22, 23 appear between the back portions 7,8 and the wall 21. If the refrigerator is placed e.g. in a kitchen, these duct portions 22.23 externally may well be limited by 10 kitchen furniture next to the cabinet.

Under skabets drift vil der fremkomme opadgående luftstrømme gennem kanaldelene 22,23, som vil kunne køle bagsidedelene 7,8. Ved beregninger og forsøg, som ligger til grund for den foreliggende opfindelse, 15 har det vist sig, at selv om der ikke findes nogen strømningskanal af betydning mellem den plane bagsidedel 6 og væggen 21, opnås der alligevel en kondensatorkapacitiet, som er tilstrækkelig. Det skal dog i denne forbindelse bemærkes, at selv om den plane del 6 er anbragt tæt ved væggen 21, vil der alligevel ske varmeafgivelse fra den plane del 20 6 nemlig i form af stråling/ledning til væggen 21. Hvis der er anbragt møbler til siden for køleskabet 1, vil der også ske køling af de der værende kondensatordele ved stråling/ledning.During cabinet operation, upward air flows will appear through duct portions 22.23, which will be able to cool the back portions 7.8. In calculations and experiments which form the basis of the present invention, it has been found that, although no significant flow channel exists between the planar backside portion 6 and the wall 21, a sufficient capacitor capacity is still obtained. However, it should be noted in this connection that although the planar part 6 is placed close to the wall 21, heat emission from the planar part 20 6 will nevertheless take place, namely in the form of radiation / conduction to the wall 21. If furniture is arranged for next to the refrigerator 1, there will also be cooling of the existing capacitor parts by radiation / conduction.

For imidlertid af forøge kondensatorkapaciteten er skabet ifølge den 25 viste udførelsesform udformet med de tidligere forklarede relativt tykke pladedele, der udgør bagsidedelene 7,8. Disse pladedele har en vis varmeakkumulerende evne, hvilket indebærer, at de kan akkumulere en del af den kondensatorvarme, der skal afgives, og afgive denne varmemængde efter, at skabskompressoren er standset. For at opnå en rela-30 tiv stor varmeafgivelse til bagsidedelene 7,8 kan kondensatorrørets rørstrenge være anbragt med mindre deling langs disse end ved den plane bagsidedel 6.However, in order to increase the capacitor capacity, the cabinet according to the embodiment shown is designed with the previously explained relatively thick plate parts, which form the back side parts 7,8. These plate parts have some heat accumulating ability, which means that they can accumulate part of the capacitor heat to be emitted and emit this amount of heat after the cabinet compressor is stopped. In order to obtain a relatively large heat release to the backside portions 7,8, the capacitor tubes of the capacitor tube may be arranged with less pitch along them than at the flat backside portion 6.

Som følge af den tætte anbringelse af den plane bagsidedel 6 mod væg-35 gen 21 kan skabets dybde forøges ud for bagsidedelen 6 svarende til det mellemrum, som ellers foreskrives for køleskabe under samtidig overholdelse af en forudbestemt indbygningsdybde, altså således, at skabets fordør 2 ikke kommer til at rage længere frem end, hvad der svarer til et køleskab med mellemrum langs hele bagsiden.Due to the close arrangement of the flat back side 6 against the wall 21, the depth of the cabinet can be increased beyond the back side 6 corresponding to the space otherwise prescribed for refrigerators while simultaneously maintaining a predetermined installation depth, so that the door of the cabinet 2 is not going to protrude further than the equivalent of a refrigerator at intervals along the entire back.
