Definitions

  • the invention relates to an evaporator for a refrigerator and / or freezer.
  • an inner container for a freezer part of a refrigerator and / or freezer which has an aluminum jacket at the top, side and bottom that serves as an evaporator surface.
  • This aluminum jacket is made from various parts, such as the front frame, back section and aluminum sheet sheaths, with a comparatively large amount of manual work (e.g. masking the butt edges, etc.).
  • Internal evaporators are usually provided in the inner container.
  • the object of the present invention is to provide an inexpensive evaporator system, in particular for the freezer parts of a refrigerator and / or freezer, which is as easy to clean as possible and in which the entire interior should be usable.
  • an evaporator for a cooling and / or Freezer from an evaporator tube attached to a one-piece inner container made of deep-drawn plastic, which is applied in an intimate connection to the surface, the inner container being insulated from the outside with foamed plastic.
  • This solution according to the invention creates a smooth inner container surface. Since there are no gaps in which, for example, fungal cultures can form, the device is easy to clean. Since there are no evaporator tubes in the interior, the entire interior volume can be used. When defrosting, the evaporator is protected from damage. There are few interfering contours.
  • a thin evaporator surface made of heat-conducting material can be applied to the one-piece inner container made of deep-drawn plastic.
  • This advantageously consists of a metal foil, for example aluminum or copper.
  • a metal foil can also be arranged as a cover between the tube and the plastic foam.
  • the inner container with two cooling compartments or cooling chambers is advantageously deep-drawn.
  • the evaporator tube can be heated directly or indirectly for targeted defrosting of the freezer or freezer compartment. This makes defrosting particularly easy and quick.
  • the tube is advantageously embedded in thermal paste.
  • the evaporator surface can be formed by means of an aluminum or copper strip laminated on one side on an adhesive layer.
  • Fig. 1 a schematic representation of the inner container of a refrigerator and freezer in a schematic representation
  • FIG. 1 shows a detail of a refrigerator and freezer combination known per se in its construction. Since it is sufficient to present the present invention, only the deep-drawn inner container made of polystyrene 10 is shown, which, starting from a plastic plate 12, has a deep-drawn inner container part 14 for the cooling device and a deep-drawn inner container part 16 for the freezer. On the outer surface of the inner container part 16, which forms the freezer part, an evaporator winding 18 is applied, which essentially consists of an evaporator tube 20 wound side by side in turns.
  • FIG. 2 The structure of the evaporator according to the invention is shown in FIG. 2.
  • a thin aluminum layer 24 laminated on one side is wound into strips.
  • the aluminum layer is laminated with an adhesive that enables gluing between the polystyrene layer 22 and the strip-shaped aluminum layer 24.
  • the strip-shaped aluminum layer 24, which is wound up next to one another, produces an aluminum evaporator surface in a fully automated manner in a simple manner and by automatic winding using a winding machine.
  • On the aluminum evaporator surface is outside an evaporator tube 20 spirally wrapped around the inner container 16 to form the evaporator tube winding.
  • the evaporator tube 20 is embedded in a heat transfer paste 26.
  • a plastic film is wrapped from the outside as the outer skin.
  • the unit consisting of aluminum strip 24, evaporator tube 20, heat-conducting paste 26 and cover 28 can be particularly advantageously simultaneously and automatically wound onto the outer polystyrene skin 22 of the freezer inner container 16 by means of a winding machine.
  • the interior is easier for the customer to clean. Due to the corresponding arrangement of the evaporator, the interior also has a larger interior volume.
