Definitions

  • the present invention refers to a container for a refrigerator and relative refrigerator.
  • Current refrigerators for domestic use normally comprise at least two compartments at different temperatures, one at a higher temperature (typically between +3°C and +6°C) for fresh foodstuffs and the other at a lower temperature (typically -18°C) for frozen and deep-frozen food.
  • Each of the two compartments is equipped with a respective evaporator, or with a respective portion of the same evaporator, which forms part of a normal refrigerating circuit with compressor and condenser.
  • refrigerators are generally "frost-free", i.e. equipped with means capable of preventing the formation of frost. For this reason a so-called “ventilated” evaporator, i.e. one which is subjected to forced air circulation, is provided in the lower-temperature compartment.
  • the object of the present invention is to provide a container for a refrigerator which allows the above disadvantages to be overcome.
  • this object is achieved by means of a container capable of being refrigerated by a frost-free refrigerator, said refrigerator comprising at least one first and one second opening and said container being capable of containing food to be refrigerated, characterised by the fact of being thermally insulated and of comprising at least one eutectic plate, an opening for the inflow of cold air connectable to said first opening on the refrigerator and a further opening for the outflow of said air from the container connectable to said second opening of the refrigerator.
  • a container for a refrigerator is shown in accordance with a first embodiment of the present invention.
  • the container comprises a compartment 1 capable of housing food to be refrigerated and another compartment 2 into which flows cold air coming from a refrigerating apparatus through a port 3; the cold air flows out through another port 4.
  • Ports 3 and 4 consist of insulated tubular elements preferably made of plastic.
  • Compartment 1 is separated from compartment 2 by means of a plurality of eutectic plates 5 arranged in the manner of a separating wall; the plates 5 are arranged on a plurality of elements 6 connected to the lower wall 7 of the container.
  • the elements 6 are arranged in such a way as to force the cold air coming from opening 3 along a particular path 8 inside the container.
  • Path 8 is preferably of serpentine type and consequently the elements 6 are arranged substantially parallel to each other and parallel to the lateral walls 9 of the container; the serpentine path means a longer stay for the cold air inside the container and therefore faster cooling of the eutectic plates 5.
  • the container is provided with a removable cover 10.
  • the container is thermally insulated so as to maintain a constant temperature for a determinate period of time; the eutectic plates 5 contribute to maintaining said temperature constant for a longer period of time. In this way the container is capable of preserving foodstuffs for a determinate period of time.
  • the container is also fitted with closing stoppers and/or valves with quick connections 11 for ports 3 and 4, preferably in polyethylene, to avoid possible falls in temperature through contact between the interior of the container and the external environment after the container has been refrigerated.
  • FIGS 5-8 a container for a refrigerator is shown in accordance with a second embodiment of the present invention.
  • the container in figures 5-8 differs from the container in figures 1-4 in that compartment 1 has a removable insulated tent-like cover 20.
  • the cover 20 is supported by a frame 21 of adjustable height so as to utilise the minimum volume in relation to the quantity of food to be kept.
  • Cover 20 has a sealing rim 22 capable of engaging with a suitable rim on the container for sealing container 1.
  • the container has an overall size variable between a minimum shown in figure 5 and a maximum shown in figure 6 .
  • Figures 9 and 10 show a refrigerator equipped with a container as described above; the container from figures 1-4 is shown by way of example.
  • the refrigerator is of the frost-free type and includes a freezer compartment 100 and a refrigerator compartment 200 at a lower temperature than the freezer compartment 100.
  • the refrigerator comprises preferably two pipes 300 and 400 connected to the refrigerating circuit 500; the openings in pipes 300 and 400 engage uniquely with ports 3 and 4 on the container for the inflow and outflow of cold air.
  • Cold air coming from the refrigerating circuit 500 is forced through pipe 300, while air flows out through pipe 400 towards the refrigerating circuit 500.
  • the refrigerator can include a first and a second opening in the pipes for the inflow and outflow of the forced air from the refrigerating circuit 500 inside the refrigerator; in said first and second openings, ports 3 and 4 on the container in figure 1 or figure 5 engage.
