Definitions

  • the present invention refers to a modular refrigeration apparatus.
  • 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 food 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 refrigeration circuit with compressor and condenser.
  • refrigerators are generally "frost-free", i.e. equipped with means capable of preventing the formation of frost on the wall of the evaporator. 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 refrigeration apparatus which is always appropriate to the needs of the user.
  • a modular refrigeration apparatus comprising a refrigeration device provided with a refrigerating circuit of frost-free type, characterised by the fact of comprising at least one thermally insulated external container, separated from said refrigeration device and capable of containing food to be refrigerated, said container comprising a first and a second port and said refrigeration device comprising at least one opening for the emission of cold air into the inside of the container through said first port and at least one other opening for the intake of air from the container through said second port, said apparatus comprising connection means between the openings in said refrigeration device and the ports on at least one said container.
  • the modular apparatus comprises a refrigeration device 100 comprising a refrigerating circuit 110 ( figures 2 and 3 ) of frost-free type and one or more containers 200 for preserving and freezing foodstuffs, located above device 100.
  • a refrigerating circuit 110 figures 2 and 3
  • containers 200 for preserving and freezing foodstuffs located above device 100.
  • Refrigerating circuit 110 of refrigeration device 100 includes in known manner an evaporator, a compressor, a filter, a condenser and flow laminators.
  • a fan 101 activated cyclically by a suitable electric motor, allows the circulation of air inside the containers 200 relating to the refrigerator. Said fan is capable of aspirating the air which passes through the evaporator and is capable of directing the chilled air to the inside of the containers 200.
  • Refrigeration device 100 comprises one or more ports 102 for the output of cold air and one or more ports 103 for air intake.
  • a modular refrigeration apparatus is shown in accordance with a second embodiment of the present invention.
  • the modular apparatus of said second embodiment differs from that of the first embodiment in that the refrigeration device 300, comprising the refrigerating circuit 110 and openings 102 and 103, is of vertical type and the containers 200 for preserving and freezing foodstuffs are located in proximity to device 300.
  • the containers 200 may also be located at a distance and linked by special connections and remote controls.
  • Both the refrigeration device 100 and the refrigeration device 300 may be equipped with a handle 105 for transport into suitable environments.
  • a container 200 is shown for the modular apparatus shown in figures 1 and 4 .
  • 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 food for a determinate period of time.
  • the container is also fitted with closing stoppers 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.
  • FIG. 11-13 another container 200 is shown.
  • the container in figures 11-13 differs from the container in figures 6-10 in that compartment 1 has a removable 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 11 and a maximum shown in figure 12 .
  • FIGS 14-17 show a kitchen including a modular refrigeration apparatus as shown in figures 1-13 .
  • the kitchen includes a refrigeration device 100 normally located under a work surface 500 while the container 200 is normally located above the work surface, preferably set up as a wall unit or inside a wall unit.
  • the refrigeration device 100 may be made up of a domestic refrigerator with external openings 102 and 103 for the delivery of cold air and the intake of recirculated air.
  • the modular refrigeration apparatus comprises connection means 150 for the flow of cold air from the ports 102 to the ports 2 on container 200 and for the outflow of air from the ports 3 on container 200 to the ports 103 on device 100.
  • Said connection means are preferably tubular pipes, thermally insulated.
  • Figures 18 and 19 show a refrigeration device 100 made up of a domestic refrigerator with external openings 102 and 103 for the delivery of cold air and the intake of recirculated air.
