Definitions

  • the invention regards a vertical freezer, particularly for household use.
  • a freezing compartment wherein the evaporator is being made of a compact and preferably ventilated battery, which is mounted in correspondence of the upper portion of the same compartment, but it will be intended that what explained may be identically implemented and so valid even for more general use, where a wide interchangeability between the mounting and the containment devices of the evaporating batteries is appreciated.
  • a freezer comprising an evaporator mounted in correspondence of an upper portion of a freezing compartment
  • DE 87 12 962 discloses a freezer, comprising an housing, thermally insulated with rigid plastic foam, whose front opening is lockable by a door; inside the housing there is an inner container where there is placed a box evaporator, under which is placed a drip tray.
  • EP 1 479 987 discloses a refrigerator provided with a preservation compartment and with an evaporator formed from extendable spiral-wound tube of engineering polymer, such as to be able to be elastically lengthened, i.e. in the manner of a spring; this enables the user to obtain a required (for example different) temperature distribution within the refrigerator.
  • This solution provides a refrigerator having a evaporator which, when in use, is able to assume different locations and sizes based on the practical utilization requirements of the refrigerator.
  • JP 2001 272152 discloses a freezer provided with a cooler chamber in which a cooling unit and a fan is placed; as can be seen in Figure 2 of JP 2001 272152 , the thermal insulation of the upper wall of the cooler chamber is reduced in correspondence to the whole cooling unit and to the fan.
  • JP 11 101562 disclosed a refrigerator provided with a compartment according to the preamble of claim 1, in which upper part it is defined a cooling section comprising a cooler and a fan.
  • a number of types of evaporating batteries have been developed and proposed, which have to maintain a basically similar mechanical solution, and in the same time have to be designed to be combined both from the point of view of the mechanical interface to the relevant different freezing compartments, and of their performances.
  • a compartment 1 of a vertical freezer is basically composed by:
  • said battery is supported, and for esthetical reasons even closed, by an outer envelope 5 closing it at least frontally and from the bottom, and usually also laterally.
  • thermal exchange i.e. a cold transfer from a generic evaporator to an outer environment
  • the most used and up to now obliged way of proceeding is to provide a specific evaporating battery and a respective specific envelope, to be mounted inside a respective compartment.
  • envelopes With reference to the implementation of the envelopes, it essentially consists in the designing and engineering of a unique type of envelope Nx, having proper size to lodge a pre-defined range of different evaporating batteries, and able to be identically mounted on the upper wall of a pre-defined plurality of freezing compartments.
  • the present solution therefore offers an useful solution to review the design and the industrial engineering of the evaporating batteries which are to be included in the method, so as to increase the number of said batteries which can take advantage of the production standardization and optimization.
  • such method consists in the design of some evaporating batteries so that they show basically the same size in width and in length, but not in height; this allows to achieve the greatest difference between the thermal exchange of the less powerful battery and the thermal exchange of the most powerful battery.
  • the figures 4a and 4b do show in a simplified way an example of a common envelope Nx associated to two different evaporating batteries B1, B2, showing respective different heights H1, H2.
  • the evaporating battery 2 is mounted so that its front side shows a slight inclination upwards; such a feature is due to the fact that, in this simple, cheap and safe way the defrost water of the evaporator 2 is automatically conveyed by gravity in a proper gutter placed in the back side of the compartment, from where it is being discharged to the outside by known means.
  • an improvement of the invention consists in implementing a cavity 6 in said upper wall, which is open downwards and has geometry, size and position able of lodging an upper portion 8 of the underlying evaporating battery 2.
  • the fig. 6 shows a different embodiment of the compartment of fig. 5 , wherein in the same cavity 6 two different envelopes, here identified with V1 and V2 and with different heights A1 and A2 , can be lodged; this means that, reciprocally to what previously explained, in the same cavity 6 a plurality of envelopes can be associated as well, in addition to the circumstance that one envelope only may contain a plurality of evaporating batteries showing different heights (provided that said heights are limited to a certain difference).
