Definitions

  • the present invention relates to a refrigerator comprising a refrigerator cabinet having a front side and a rear side, a mantle for said cabinet and a condenser comprising a pipe coil which is arranged at the inner side of the mantle at said rear,side of the cabinet in good heat conducting connection therewith.
  • Refrigerators of the kind referred to above are known from common use, wherein the reverse side of the cabinet is planar. Such refrigerators are installed at a predetermined minimum distance from the wall along which the refrigerator is arranged, viz. in such a way that an air flow passage is formed behind the refrigerator having a flow area sufficient for the flowing air to remove the necessary part of the heat generated by the condenser. Due to the fact that the so-called "built-in measurements" as a rule are standardized, which means that the front surface of the refrigerator should not be positioned further away from the wall along which the refrigerator is arranged than a predetermined distance, the observance of the minimum distance between the reverse side of the cabinet and the wall constitutes a limitation as regards the usable volume of the cabinet.
  • the refrigerator according to the present invention is characterized in that the rear side comprises a generally planar part and rear side parts extending laterally at both sides of the planar part and being positioned closer to the front side than the planar part, the pipe coil being arranged at the inner side of the mantle at said planar part and at the rear side parts.
  • a particularly simple embodiment of the refrigerator is according to the invention characterized by the planar part being constituted by a vertical central part of the rear side and by the rear side parts extending laterally with respect to the planar central part being constituted by planar side parts defining equal, toward the front side of the cabinet open, obtuse angles together with the planar central part.
  • the obtuse angle may lie between approximately 130-165°, preferabley between approximately 140-160° and, more preferably, being approximately 150°.
  • At least the rear side parts extending laterally with respect to the planar part may be constituted by material having a high heat capacity per unit of area being of a value which ensures that said rear side parts will be able to act as heat accumulators because they, when the refrigerator is started, will be able to accommodate a part of the condenser heat and after the refrigerator has been stopped, they can emit the heat accumulated whereby the period during which the emission of the heat lasts, may be increased beyond the period during which the compressor works whereby the capacity of the condenser will be increased.
  • the rear side parts may according to the invention consist of metal sheet material having a thickness being larger than the thickness of the sheet material for the remaining part of the mantle.
  • metal sheet material having a thickness being larger than the thickness of the sheet material for the remaining part of the mantle.
  • such material steel having a thickness of approximately 2 mm may be mentioned as compared with a thickness of the sheet material for the remaining part of the mantle of the cabinet of 0.6 mm.
  • the condenser may be shaped as a pipe coil having vertically extending pipe strings.
  • the pipe strings of the condenser may be arranged closer adjacent each other at the rear side parts extending laterally with respect to the planar part than at the planar part.
  • the total width of the side parts may constitute between approximately 20-50%, preferably between approximately 25-35% and, more preferably, may constitute approximately 28% of the total width of the cabinet.
  • the cabinet has planar side walls 3,4 and the reverse side is indicated by the numeral 5.
  • the reverse side comprises a planar part 6 and along both sides of the planar part 6 rear side parts 7,8 extend, which are arranged closer to the front door 2 of the cabinet than the rear side part 6 because the side parts 7,8 extend under an obtuse angle with respect to the planar part 6.
  • This angle is according to the embodiment shown in the drawings approximately 150° but may lie between approximately 130-165° and, preferably between approximately 140-160°.
  • the total width of the side parts constitutes approximately 30% of the total width of the cabinet but the width of the side parts may vary between approximately 20-50%, preferably between approximately 25-35% of the total width.
  • the cabinet is provided with a refrigerating assembly which according to the embodiment shown comprises a compressor 10 to which a condenser 11 belongs.
  • the condenser is constituted by a pipe coil having vertically extending pipe strings as indicated schematically with broken lines in fig. 1.
  • five condenser pipe strings are provided at the planar part 6 as indicated in fig. 2, one string is arranged at the transition to each of the side parts 7,8, one string is arranged along each of the side parts 7,8, one string along the rear edge of each side wall 3,4 and one string along each of these rear edges.
  • the pipe condenser 11 is arranged inwardly with respect to the mantle or outer covering 14 of the cabinet and is connected with the mantle or outer covering in a good heat conducting way because the pipe coil is adhered by means of good heat conducting adhesive mass 15.
  • the side part 8 consists of sheet material which in the case illustrated is constituted by a steel plate having a thickness of 2 mm.
  • the other side part 7 is shaped correspondingly.
  • the remaining part of the mantle 14 of the cabinet consists of steel sheet material having a thickness of approximately 0.6 mm.
  • the side parts 7,8 are connected with the adjacent sheet edges e.g. by welding or in any other way, which results in a sealed connection. Furthermore, the cabinet is provided with an insulation, not shown, which ajoins the inner surface of the outer coating.
  • planar part 6 is connected with an inclined top side part 16 and, furthermore, the top surface of the cabinet is constituted by a planar top part 17.
  • planar part 6 merges into an inclined rear wall part 18 which ends at a ceiling 19 for a recess 20 wherein the compressor is arranged.
  • the refrigerator shown operates in the following way:
  • the cabinet is installed with the planar rear side part 6 in the immediate vicinity of a wall which is indicated by means of a line 21 in fig. 2.
  • duct parts 22,23 having wedge shaped cross sections are formed between the rear side parts 7,8 and the wall 21. If the cabinet is arranged for instance in a kitchen, the duct parts 22,23 may laterally be limited by adjacent kitchen furniture.
  • the refrigerator in order to increase the capacity of the condenser the refrigerator according to the embodiment shown is provided with the comparatively thick plate parts which, as previously explained, constitute the rear side parts 7,8.
  • These plate parts have a certain heat accumulating capacity and, accordingly, they may accumulate a part of the condenser heat to be emitted and they may emit this heat after the compressor of the cabinet has been stopped.
  • the pipe strings of the condenser pipe may be arranged with a smaller pitch along the rear side parts 7,8 than along the planar rear side part 6.
  • the depth of the cabinet may be increased in front of the rear side part 6 corresponding to the gap which otherwise is prescribed for refrigerator cabinets and, simultaneously, a predetermined building-in depth may be respected, viz. in such a way that the front door 2 of the cabinet does not extend further forward than corresponding to a cabinet arranged with a gap between the reverse side and the wall along the full width of the rear side.
