Definitions

  • This invention relates to a static (ie not forced-air) refrigerator provided with a plate evaporator or an evaporator embedded in insulating material for cooling a refrigeration compartment or chamber.
  • An object of the present invention is therefore to enable static refrigerators of the initially specified type to produce ice blocks, cubes or similar pieces.
  • a further object of the present invention is to enable these specific refrigerators to produce ice pieces by simple relatively economical means of small overall size and at least in part removable, which utilize the cold generated by the evaporator to form said pieces and to preserve them in the solid state, even during refrigerator defrosting, by virtue of a cold accumulation principle.
  • the reference numeral 1 indicates overall a static refrigerator comprising a refrigeration chamber 2 bounded by walls 3a, b, c.... pertaining to an inner liner 4.
  • This inner liner is contained in but spaced from an outer housing 5, between the two there being provided insulating material 6 in which there is embedded a hairpin coil 7 forming the evaporator of the refrigerator refrigeration circuit and positioned against the outer face 8 of the walls 3a, b, c of the inner liner 4, but preferably prevalently against the wall 3b and only partly against the walls 3a and 3c.
  • support and positioning means 9 in this example in the form of a dovetail or undercut guide of aluminium or another good heat conducting metal
  • a container 10 of relatively thin plastic material which is provided with counter-means 10A corresponding to the means 9, for its removable support and positioning.
  • the container 10 which is hence maintained in contact with the cold wall 3b, contains a known eutectic mass which preferably has a solidification point not less than -7°C, and comprises in its upper part a series of cells 11 to contain the water to be transformed into ice pieces (for example cubes or the like).
  • the container preferably has a wedge-shaped cross-section.
  • the cells 11 pertain to a tray 12 which can be inserted into and extracted from a corresponding cavity 13 present in the eutectic container.
  • the embodiment shown in Figure 4 (in which equal or corresponding parts have the same reference numerals as heretofore) relates to a static refrigerator in which the evaporator is in the form of a substantially flat plate or body 14, comprising in known manner a channel or duct for the refrigeration fluid.
  • This plate is situated, ie extends, within the refrigeration chamber 2, almost against the inner face of the wall 3b and supported by the latter by known fixing means indicated by 15.
  • the eutectic container 10, which can comprise incorporated cells 11 as in Figure 2 or have the cells provided in a removable tray as in Figure 3, differs from the containers of these figures only by comprising hook-like appendices 16 for suspension from the upper edge 17 of the plate evaporator 14.
  • the container 10 When water has been fed into the cells 11, the container 10 (or tray 12) is positioned in the refrigeration chamber 2 as shown in the figures. During the time in which the evaporator produces cold, the eutectic passes to the solid state and the water is transformed into ice. During the defrosting of the evaporator, in the course of which it does not provide cold, the eutectic may pass to the liquid state, transferring considerable cold to the ice pieces and hence preserving them in this state.
  • the user When the user wishes to procure the ice pieces, he removes the container 10 (in the case of the containers of Figures 2 and 4) or the tray 12 (in the case of Figure 3) and separates these pieces by deforming the container 10 or tray 12, possibly heating and softening the container under a water jet from a tap.
