Definitions

  • the invention relates to a refrigerator according to the preamble of claim 1.
  • Refrigerators have a closed interior, which is cooled by a refrigerant circuit.
  • a compressor is provided on the outside of the refrigerator, which compresses the gaseous refrigerant and thereby heated.
  • the condenser which is also attached to the outside, usually on the rear wall, the refrigerant releases its heat to the ambient air and is thereby liquefied.
  • the pressurized liquid refrigerant expands into the evaporator in the interior of the refrigerator. It cools down strongly and returns to the gaseous state.
  • the air In the cooled interior of a refrigerator, the air, the z. B. When the door is opened, it cools down and condenses the moisture it contains. In order to dissipate the condensation, a channel is usually provided on the rear wall of the interior, which at its lowest point has a drain to the outside of the rear wall. There, the condensed water is introduced into an evaporation tray, which is arranged at a warm point, for example, over the compressor.
  • the size of the evaporation tray depends on the speed with which the condensate can evaporate. In order to keep the evaporation tray as small as possible, the condensate must therefore be supplied as much heat. It has therefore proven to be beneficial to lead a pipe section of the hot tube condenser through the evaporation tray so that it heats the condensate and thus rapid evaporation is stimulated.
  • the invention has for its object to form a refrigerator so that a pipe section of the tube condenser with a clamp securely in the
  • Evaporation tray can be attached. Furthermore, the clip should be inexpensive to manufacture.
  • Tube section enclosed by three sides and therefore can not slip past the holding section over. Since the channel is pressed by the clamp down to the bottom of the evaporation tray, the pipe section is enclosed by four sides and can not leave this closed channel even with tensile forces occurring.
  • the clip is U-shaped and is slipped over the outer wall of the evaporation tray. In this way one obtains access to the outside of the evaporation tray and the holding action of the clip is not limited exclusively to a clamping fixation on a wall.
  • the extending on the outside of the evaporation shell leg of the clip ends in a hook, which is supported on the underside of the evaporation tray.
  • the clamp so to speak, surrounds the bottom of the evaporation tray by pressing the channel-shaped holding section from above and the hook from below against the floor.
  • a simple removal or release of the clip can thus be excluded.
  • the hook has a bevel on its front. Through this slope, the hook slides well over the edge between the side wall and bottom of the evaporation tray. Also, a protrusion provided on the ground or an extension of the side wall beyond the ground can be overcome so well.
  • a kink is provided in the extending on the outer wall of the evaporation shell leg of the clip. By pressing on the kink, the leg can be minimally extended during assembly of the clip until the hook has taken its final detent position.
  • an extension is provided on the channel-shaped holding portion with which the clamp is supported on the inside of the outer wall in the vicinity of the upper edge. Since the outer leg is also at the top of the evaporation tray in contact with this, a secure and defined fit of the clip is guaranteed.
  • the clip is made of plastic. This means that the clamp is absolutely corrosion resistant and has a much longer life than a spring steel clamp.
  • the clip can be inexpensively manufactured as an injection molded part. However, the production is even cheaper when a corresponding plastic Profi I is extruded. From this profile then the brackets can be cut to the required width.

  • the tube 2, which is flanged to the compressor, not shown here, is guided into the evaporation tray 4 as far as possible directly.
  • the pipe section 8 remains in the bottom region of the evaporation tray 4, a certain vertical pressure must be exerted on the pipe section 8, but not allowed to be too strong.
  • the gaseous refrigerant is compressed by the compressor and thereby heated. Consequently, the gaseous refrigerant has its highest temperature immediately after the compressor. On its way through the condenser 1, the refrigerant cools and liquefies before the throttle. 6
  • the arranged below the condenser 1 evaporation tray 4 should evaporate in the shortest possible time from the cooled interior condensate.
  • the evaporator shell 4 is connected to the compressor by pulling a tube piece 8 filled with the hot refrigerant over the bottom 9 of the evaporator shell 4. So that the pipe section 8 remains permanently in the region of the bottom 9 of the evaporator shell 4, it is secured in the vertical direction by means of a pipe clamp 5, which latches with the evaporator shell 4.
  • FIG. 2 shows, as a detailed drawing, the pipe clip 5 latched into the evaporator shell 4 with the pipe section 8.

  • the stiffener 12 also rotates at right angles to the underside of the evaporator shell 4 and is slightly offset from the outer wall 10 inwards.
