Definitions

  • This invention relates to a plurality of cold-storage elements for a chest freezer, each element comprising a casing of plastics material, for example polyethylene, containing a eutectic solution, for example, based on sodium and/or ammonium salts.
  • these elements are used in chest freezers in order to maintain suitably low temperatures for reasonably lengthy periods in the event of failure of the electricity supply which feeds the freezer compressor.
  • the storageelements can be used in such a manner that the eutectic solution becomes frozen by practically continuous operation of the compressor during those (night) hours in which the mains electricity is sold at reduced tariff.
  • the thermal energy stored by these elements is.then utilised during those (day) hours in which the mains electricity is sold at full tariff, so avoiding operation of the freezer compressor during these hours.
  • the storage elements constitute a structural part of the chest freezer in the sense that they are incorporated in the structure of the chest freezer structure in a non-removable manner.
  • This constitutes a drawback in that it compels freezer manufacturers to produce freezers both with and without cold storage because there is a user requirement for both types of freezer.
  • it is not possible to change the overall storage capacity of a freezer fitted with cold storage, should the user so desire.
  • the present utility model invention provides a plurality of cold-storage elements which are each constructed to be removably mounted in a chest freezer in contact with a refrigerated wall thereof so as to extend over at least a portion of this wall, and are provided with means whereby they can be fitted to one another by inosculation, and with means for remoably connecting them to the freezer.
  • the invention also provides a cold-staage element for use in the plurality of such elements, the element comprising a casing of plastics material containing a eutectic solution, characterized in that the storage element is constructed to be removably mounted in the freezer in contact with a refrigerated wall thereof so as to extend over at least a portion of this wall, and is provided with means whereby it can be fitted to another storage element by inosculation, and with means for removably connecting it to the freezer.
  • the sealable apertures 15 for changing the element with the eutectic solution and the cup-shaped stiffening recesses 16 each of the curved-end storage elements 4, as shown in Figures 7 to 10, also comprises a central vertical hollow rib 20 on one of its minor vertical sides, and on the other minor vertical side a pair of spaced vertical hollow ribs 21 which between them define a groove 22 to receive the hollow rib 13 of an adjacent flat element 3.
  • the rib 20 of each curved-end storage element 4 fits between the hollow projections 14 of the other adjacent flat element 3.
  • the storage elements 3, 4 are mounted in the chest 8 of the freezer 1 by first hanging them one at a time on the upper edges 7 of the walls of the chest by means of their flanges 9, then fitting them laterally into each other by. the aforesaid inosculation means, and finally inserting the flat grids or braces 10 into the grooves 12 in the flat storage elements 3.
