Definitions

  • the present invention refers to a refrigerator appliance with refrigeration grid provided with eutectic plates, in particular to a freezer. Even more in particular the present invention refers to a household freezer.
  • EP-A-1 006 324 and WO 01 27551 A show a refrigerator shelf made up of a cooking serpentine and tool elements which form a grid structure with passages into which a container of eutectic mixture is inserted.
  • scope of the present invention is to realise a refrigerator appliance that allows to obtain an energy consumption lower than the known freezers.
  • a vertical freezer comprising a cabinet 1 and a refrigeration grid 2 according to the present invention.
  • the refrigeration grid 2 is arranged along the entire width and the length of the cabinet 1 so as to define horizontal shelves 3 that are arranged at a certain distance the ones from the others and made up of a cooling coil 4.
  • Such shelves 3 are transversally connected the ones with the others by means of rods 5 and 6 that are transversally welded below and above the cooling coil 4 and that are fastened to the side walls of the freezer by means of supports 7.
  • the cooling coil 4 of the shelves 3 forms external folds 8 with a small length of coil and folds 9 with a greater length of coil so as to create appropriate housings 20 that are suitable to receive eutectic plates 10 of a first type that are arranged horizontally, as shown in Figures 3a, 3b.
  • Such eutectic plates 10 are removably fastened to the cooling coil 4 of every shelf and precisely they are connected with the folds 9 so as to occupy a space almost equal to one time and a half the housing 20.
  • the plates 10 are coupled to the coil 4 in order to have considerable contact points both with the same coil 4 as well as with the rods 5 and 6 that are welded to the coil 4 so as to facilitate the thermal exchange.
  • Such eutectic plates 10 have a small thickness but wide lateral surfaces, they are made up of a container generally made of plastic material and they contain an amount of eutectic solution of approximately 0.6 litres.
  • shelves 3 are also present that are provided with eutectic plates 11 of a second type that are smaller than the eutectic plates 10 and inserted horizontally each one in every housing 20 of the folds 9 of the coil 4 in an extractable way, as shown more in detail in Figures 4a, 4b.
  • eutectic plates 11 are coupled to the coil 4 too, in order to have considerable points of contact with it and with the rods 5 and 6 that are welded to the coil 4 and they have a smaller extension of the lateral surfaces.
  • Such plates 11 are made up of a container that is generally made of a plastic material and they contain an amount of eutectic solution of approximately 0.14 litres.
  • the refrigeration grid 2 that is part of a refrigerating circuit (not visible in the figures) comprising an opportune compressor and a condenser, allows to have shelves, each having equal temperature, at various temperatures, and precisely at increasing temperature from the top towards the bottom in cabinet the 1 of the freezer. Therefore it is possible to have shelves 12 to deep freeze food with temperature at -30°C, shelves 200 for quick freezing with temperature at -26°C, medium freezing shelves 13 with temperature at -22°C, storage shelves 14 with temperature at - 18°C.
  • At least one shelf 15 at differentiated and sectorial eutectic temperature on a same shelf 3 by using eutectic plates 10, 11 at a different temperature on the same shelf 15.
  • the shelves provided with eutectic plate 10, 11 are arranged vertically at a given distance the ones from the others so as to define respective containers 40-45 for the cooling of foods inside the cabinet 1.
  • Such containers 40-45 are closed by respective doors 50-55 while the entire cabinet 1 is closed by a door 60.
  • the eutectic plates 10 and 11 allow a homogenisation of the temperature in the different shelves, that, especially when the compressor is cyclically in pause, allow an increase in times of temperature raise, thus diminishing the energy consumption.
  • the eutectic plates 10 and 11 have various colours according to the type of eutectic solution contained and they can have the temperature directly stamped on the container.
  • the cooling coil 4 defines housings 20 for eutectic plates 10, 11 with a constant pitch.
  • each one of the shelves 3 comprises the same number of housings 20 for eutectic plates 10, 11.
