Description

1 AN INSTALLATION FOR PIPING IN FRIDGES 3 2 This invention is an

installation for fridge piping that has at least one tubular pipe positioned inside the body-wall of the refrigerator, the ends of which use cells of the latter for communication; the body-wall is provided with at least one hole on the inside of its sheet-wall; in which one of the ends of the pipe is situated in such a way as to connect at least two elements of the fridge through the interior of the bodywall.

In the construction of fridges in a traditional way, the elements are situated in specific areas of the inner wall, always in view. Several of these elements (for example the evaporator and the thermostat) have to be in contact. At present, these connectionelectric are attached to the inside wall of the fridge with the consequent occupation of space and risk of deterioration, The present method envisages a new installation for fridge piping, in which in the interior of the fridge wall during its manufacture-at least one interior pipe is included which puts at least two basic elements of the fridge in communication with each other, (for example the thermostat and the evaporator).

If, as is happening in recent times, the evaporator is situated in the body-wall of the fridge, a solution envisaged for the 0 device for model 8702466 of the same application- there is only one hole for the interior sheet-wall, in the area attached to the thermostat. If, on the other hand the elenents are in view, there will be two access holes. In the event of the interconnetion of more than two exterior elements being required, it is sufficient to make more access holes, as lon- as the interior pipes are kept.

0 Figure 1 shows a general scheme of the installation for piping in fridges as in the invention, f or the case of only one hole (22) to the exterior - evaporator (4) hidden.

Figure 2 shows a general schematic wiew of the installation for piping in fridges as in the invention, similar to figure 1 for the case of two holes (22), (23) to the exterior-evaporator (4) in view.

A case of this being carried out in practice, unlimited, is described below. Other ways of carrynS out this such as models that introduce accesory changes that in no way alter their working, are by no means ruled out this invention does in fact include all the variations.

In accordance with that which has been shown and according to the present achievement, the installation f or fridge piping basically contains:

- At least one pipe (1) inside the wall (2) of -the fridge.

- At least one hole (22), (23) to the outside of the same wall (2), made in the sheet-wall inside of the fridge.

The inside piping (1) is inserted or shaped into the wall durinS the process of manufacture (2) and the connections of elements (3) pass through the interior, (4) in the example where the thernastat (3) and evaporator of a fridge is made.

0 q This piping (1) assumes at least one hole (22) to the 1 - ' A C-= e,-,zvisared Ln the i.-',er4or 121) t--^ t- 1 - ' t- 0 --- -----Z:1-,2 --7 1h - 3 connect exterior element (s) (3) attached to the wall (2) or with interior elements (4) inserted in the fridge wall-a practical construction show in figure 1.- In this construction the piping (1) reaches the evaporator bulb being set onto a mouth-piece (5), on the bulb of the evaporator (4) inserted in the body of the wall (1) during the manufacturing process and which defines the entrance hole, at least (5) where the tubular pipe rests (1) and a rear hole (50) on which a thermic insulating plug (52) is placed, which on being renoved opens to the bulb of the evaporator (4) from the rear exterior face (24) of the aforementioned sheet-wall (2).

Without altering the basic nature of the invention in any way, and preserving the configuration of the installation as it was visualized, it can, in accordance with the needs., a) Connect two or more interior elements (4) it is sufficient to remove holes (22), (23), b) Connet two or more exterior elements (3), making more than one hole (22), (23) in sheet-wall (21).

c) Connet two or more elements, some exterior (3) and other interior (4) making holes (22), (23) that are necessary in each case.

In particular, and for the example of construction described, the elements (3), (4) to be connected are the thermostat (3) and evaporator (4) of a fridge.

Claims (4)

CLAIMS-:-

1. Installations for refrigerator piping, characterised because it contains at least one tubular pipe situated internally in the body-wall of the fridge and whose ends r ely on elements of this for connection; this body-wall is provided with at least one hole in the interior sheet- wall in which one of the ends of the pipe is situated in such a way that at least two elements of the fridge come into contact through the interior of that body-wall.

2. Installations for fridge pipes, as in claim 1 characterised because at least one of the constituent elements of the fridge that come into contact is outside the body-wall of the fridge.

3. Installation for fridge pipes, as claimed in claim 1 or 2 characterised because at least one of the tubular pipe situated inside the body-wall of the fridge, rests on a mouth-piece, supporting the evaporated bulb, inserted in the body-wall and structured in:

a) a cap for holding the bulb, which also contains the internal tubular piping. b) An insulating thermal plug, set in the cap which allow access to the bulb from the outside face of the aforementioned bodv-wall.

4. Installation for fridge piping, as in claim 1, -9 or 3 characterisecd by the fact that those elemen-('-s o-F the fridge Tk 11 to make contact are the thermostat and the evaporator bulb.
