Definitions

  • the present invention refers to refrigerators having at least two chambers which are operated at different temperatures.
  • the systems according to the invention comprise a deep freezing chamber which is accessible from above and surrounded by cooling elements in which a refrigerant evaporates and from which is derived the cold required in an adjacent chamber in which the temperature is higher than in the deep freezing chamber.
  • An apparatus according to the invention is suitable, for example, for short-time storage and conservation at temperatures above zero of quickly perishable food stuffs, as well as for freezing food such as meat, poultry, fruit, vegetables, liquids, etc., at below zero temperature. It is also suitable for producing ice cream, ice cubes, quick cooling of liquids, mixing and simultaneously cooling liquids, etc.
  • a further object of the invention resides in the provision of improved arrangements of the cooling chambers, of the cooler, of the drive mechanisms for mixers, agitators, and the like, and in the provision of controls for air circulation and temperature in the refrigeration and deep freezing chambers.

It is preferably cylindrical, although it may be angular or oval if desired, and comprises a flat bottom plate 29 on the lower side of which is a cooling coil 30 which continues as a cylindrical cooling coil II. The latter may be protected on the inside by a perforated sheet 3
  • the chamber formed by cooler 4 may be covered by a removable lid 33.
  • Cooler 4 is intended for storing foods requiring a temperature below zero, for freezing victuals, such as meat, poultry, fruit, and vegetables, as well as for making ice cubes.
  • a container 41 having a partition 48 for sub-dividing it into a plurality of separate receptacles as shown in Fig. 6 may be inserted in cooler 4.
  • Figs. 7 and 8 illustrate diagrammatically a mechanism adapted to be inserted in cooler 4 for making ice cream, and for mixing and simultaneously cooling liquids.
  • a drum 34 is placed on the bottom plate 29. Inside the drum is a conventional agitator or stirrer 35 having a hub portion 36 which is slipped over a shaft 31 and tightened thereon by a screw 38. The lower end of shaft 31 protrudes from the bottom of drum 34 so far as to also extend through plate 29 and coil 30 and is coupled to the top of shaft 6 (Fig. 1).
  • Shaft 3'! is preferably made of material of low heat conductivity. This device can be used in connection with all illustrated arrangements.
  • cooler 4 which is shown diagrammatically in Fig. 9, the bottom coil 30 is laid in recesses 38' provided in the lower side of plate 29. The part of the recesses not taken up by the pipes 30 is filled with material 39 having good heat conductivity.
  • This modification of the deep freezing chamber can be used with all arrangements shown in the drawings.
  • the walls of the cooler 4 may be made hollow as shown in Fig. 10, and the refrigerant may be evaporated therein instead of in cooling pipes.
  • cooling pipes ll may be accommodated inside the hollow walls and the space left may be filled with eutectic brine. This is shown in Fig. 11.
  • chamber 3' comprises a jacket I2 lining the side and bottom walls of the chamher and separating it from chamber 2.
  • the jacket is filled with eutectic brine which is cooled or frozen by refrigerant evaporating in pipes 13 disposed inside the jacket.
  • the latter communicates with a jacket l4 lining the side and bottom walls of chamber 2.
  • throttle means are provided such as a damper IS.
  • the top of both chambers 2 and 3 is closed by a removable cover l6.
  • An aperture l1 extends through the bottom wall and the adjacent jacket of chamber 3 for accommodating a drive shaft such as is designated by numeral 6 in Fig. 1.
  • cooling pipes iii are embedded in portions of the insulating casing l forming the side and bottom walls of chamber 3 and are ing chambers 2 and 3.
  • freezing cooler 4 is constructed as a container similarly to the one shown in Fig. 1, cooling pipes l I being disposed adjacent to the bottom and side walls.
  • the cooler is disposed in the upper part of a container I and separated from the lower part of the container by air flow throttling means shown as shutters 8.
  • the shutters are operated by a thermostat 9'.
  • the container of cooler 4, as well as the top part of the interior of container I" are accessible through a lid 23 which is hinged at 24 to container or casing I.
  • Chamber 2' in the lower part of casing I is accessible through door 22'.
  • An engine compartment 4' is arranged below the chamber 2'.
  • Lid 23 has an aperture 25 for receiving a shaft '6 extending down from a mo- ,tor 26 and adapted to be coupled at 2'! to the shaft of an agitator or stirrer 28 for making ice cream or liquid mixes.
