Definitions

• the invention regards an improved method for producing freezing compartments of vertical freezers, particularly for household use, implemented by a special combination of components which allow an high interchangeability and modularity.
• 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 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.
• - fig. 1 shows a simplified and transversal sectional view of the compartment of a vertical freezer, according to the prior art
• - fig. 2 symbolically shows a schematic of the logical assembly of some main components of the freezer compartment of fig. 1 ,
• - fig. 3 symbolically shows a schematic of the logical assembly of the main components of the freezer compartment according to the present invention
• - figures 4a and 4b show respective simplified exploded views of two possible different embodiments of this invention
• each envelope is able to the double function both of containment of the respective evaporating battery Bl, B2 B3, and of its mounting to a respective type of compartment Cl, C2, C3, as exemplarily and schematically shown in fig. 2.
• 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 predefined 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 instant 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 Bl, B2, showing respective different heights Hl, 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.
• a solution implies that an about prismatic room
• an improvement of the invention consists in implementing a cavity 6 in said upper wall, which is open downwards and having geometry, size and position able of lodging inside it 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 Vl and V2 and with different heights Al 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) .
