Definitions

  • the present invention relates to an improved cooling system for a refrigerator, preferably a domestic refrigerator, comprising a cell in which is located at least one compartment for the storage of food below freezing point, with said compartment being cooled by means of at least one wire tube evaporator arranged on at least one wall of said cell.
  • a refrigerator cooling system of the aforementioned type is known.
  • the drawback of this solution lies in the fact that, with the method described, the usable volume of the refrigerator is greatly reduced.
  • the object as set above is achieved according to the present invention in a manner that a wire tube evaporator arranged in the interior of a refrigerator cell being linked hydraulically with a tube evaporator extending in a form similar to a coil along the outer periphery of said compartment.
  • said tube evaporator can extend in a meander-like manner in the plane of at least one of the walls of said cell of the refrigerator. Said tube evaporator furthermore extends entirely in the insulation of said cell. It is provided for, according to the invention, that said tube evaporator is installed in the refrigerator before the installation of the insulation and before the assembly of the refrigerator.
  • said wire tube evaporator is installed in said refrigerator when the latter is completely assembled, with each free end of said wire tube evaporator being hydraulically connected to each free end of said tube evaporator projecting inside the cooling area of the refrigerator. Furthermore, each said free end of said wire tube evaporator is connected hydraulically with each said free end of said tube evaporator by means of a cold junction provided by mechanical deformation.
  • the refrigerator according to the invention comprises a cell 1, inside which is located a refrigerating space 2 being divided vertically into several compartments where drawers for the freezing and/or storage of food are located. Each said compartment and drawer, respectively, is separated in a manner known per se by means of a wire tube evaporator 3, 4, 5, each of which is preferably arranged in a horizontal plane. Said cell 1 of the refrigerator is surrounded by an insulation not shown. In order to improve the efficiency of the refrigerator, said cell 1 is surrounded in a form similar to a coil 6 by a tube evaporator 7, extending entirely within the insulation of said cell 1. Obviously, it is understood that, without departing from the spirit and scope of the invention, said tube evaporator 7 can extend in a meander-like manner in the plane of at least one of the walls of said cell 1.
  • first end 8 of said wire tube evaporator extends from a condenser not shown into the cell 1 in a manner known per se. Said first wire tube evaporator 3 then extends into the second wire tube evaporator, which is shown on the diagram as the middle wire tube evaporator 4, and extends onward into the third wire tube evaporator, which is shown on the diagram as the lower wire tube evaporator 5.
  • the free end of said lower wire tube evaporator 5 is connected in the area of the wall to the tube evaporator 7, which at the point 10 passes through the wall of said cell 1 and exits said cell 1 and, as already mentioned, in the manner similar to the coil 6 winds around said cell 1 in the insulation of the cell 1.
  • the free end 11 of said tube evaporator 7 at the point 9 passes through the wall of the cell 1 and extends in a manner known per se either into the refrigeration unit or the compressor of the refrigerator.
  • the path of the cooling medium may also be inverted. This means that the first end 8 of the first wire tube evaporator 3 extends from the compressor not shown into the cell 1 in a manner known per se, and the free end 11 of said tube evaporator 7 passing through the wall of the cell 1 at the point 9, extends into the condenser in a manner known per se.
  • said tube evaporator 7 is wound around said cell 1 before installation of the insulation and before assembly of the refrigerator. It is also provided for that each of said wire tube evaporators 3, 4, 5 are installed in the refrigerator when the latter is entirely assembled.
  • connection between the wire tube evaporator 5 and the tube evaporator 7 is formed by means of a cold junction provided by plastic deformation.
