Abstract

The present patent application relates to a system, which can be possibly mounted in a traditional refrigerator, designed to vacuum pack one or more removable containers used for fresh food preservation.

Description

Description
System for vacuum preservation of food in domestic environment.
The present patent application for industrial invention relates to a system for the vacuum preservation of food in domestic environment.
As it is known, most fresh foods tend to degrade when stored inappropriately.
Cold preservation has been traditionally considered as a very efficacious solution to preserve foods for medium-long periods of time.
Recently, vacuum preservation of fresh foods, such as vegetables, ham, meat, cheese, etc., has become popular.
In fact, a large number of shops offer similar foods in vacuum packages. To carry out such an activity, special machines are used to seal the food to be preserved inside plastic bags, after extracting the air contained in said bags.
It is worthless saying that perfect preservation is guaranteed when the two aforementioned technologies are combined, that is to say food is vacuum packed and stored in refrigerated condition.
However, it must be noted that the current vacuum packing technology is not able to satisfy the needs of potential customers at best, especially in a domestic environment.
So far, only shops equipped with the aforementioned vacuum packing machines can preserve food in this way, and not final consumers who have bought a product that was not originally vacuum packed.
Another negative situation is encountered when the user has bought a vacuum packed product and wants to open the package to use part of said product, without the possibility of closing the package and vacuum packing the remaining product.
A careful examination of these problematic issues has resulted in the system of the invention, the main purpose of which is to allow final consumers to vacuum pack and/or vacuum preserve any type of food, regardless of the fact that the same was sold or not in vacuum package.
In particular, the system of the invention comprises a preferably parallelepiped supporting structure, which includes two different spaces, a front space adapted to preserve foods and accessible for the final user, and a back space adapted to contain the means for the operation of the same system and not accessible for the final user.
The front space is provided with a plurality of compartments, each of them exactly housing a basically parallelepiped rigid container for preservation of fresh foods that can be closed hermetically.
The back wall of each container is provided with a fast-coupling valve for connection with a corresponding pneumatic nozzle that protrudes from the front wall of said "technical" compartment of the system of the invention.
In fact, each nozzle is connected with a vacuum pump housed in the back space of the system of the invention, together with the electrical and electrically-operated electronic parts that guarantee correct operation.
It appears evident that first of all the user of such a system must store foods in one of said containers, and then insert it in one compartment of said front space of the system of the invention, in such a way that the back valve is connected with said pneumatic nozzle.
A similar connection causes the automatic operation of the pump contained in the back space of the system of the invention, rapidly obtaining vacuum packing of said container.
It must be noted that the valve provided on the back space of the system is of unidirectional type, so that vacuum packing is maintained until the airtight lid is not removed from the container by the final user.
Until said operation is not carried out, after checking the production of vacuum packing, the final user can remove said container from the system of the invention and place it in a different location, without the risk of food deterioration at least until the lid is opened again.
Evidently, the best location of a similar system is inside a refrigerator, since in such a case the final user of a similarly equipped refrigerator can take advantage of the benefits of cold and vacuum packing for food preservation.
In such a case, the system of the invention can be possibly positioned in the "main" compartment of a refrigerator or in the quick-freezing compartment if longer preservation is needed.
Considering that the various containers of the system of the invention can be also extracted from the corresponding space after being vacuum packed, even if longer preservation is needed, the system of the invention can be positioned in the "main" compartment of the refrigerator and the containers can be moved to the quick-freezing compartment only after they have been vacuum packed.
Finally, it must be noted that the system of the invention can be installed inside a refrigerator during the manufacturing process of the refrigerator, thus creating a basically new type of "bivalent" household appliance.
Nevertheless, the system of the invention can be advantageously mounted also in traditional refrigerators as optional accessory.
In fact, the system of the invention is completely independent in functional and structural terms, with the only need to have an electrical connection to power the operational parts.
Such a connection can be obtained by means of the electrical cables that power the devices that are normally provided in the refrigerator compartment, such as the internal lamp or the switch used to turn on or off the lamp when opening or closing the door of the refrigerator compartment. For purposes of clarity, the description of the invention continues with reference to the enclosed drawings, which are intended for purposes of illustration only and not in a limiting sense, wherein:
- figure 1 is a partially cross-sectioned exploded axonometric view of the system of the invention inside the refrigerator equipped with it; - Figure 2 is a side view that basically corresponds to said cross-sectioned detail of figure 1 ;
- Figure 3 is a block diagram of the system of the invention. - A -
As mentioned above, Figures 1 and 2 show a cabinet (M) equipped with the system of the invention (1 ); preferably, said cabinet consists in a traditional refrigerator.
The system has a basically parallelepiped structure that comprises two spaces (2, 3) separated by a transversal wall (4).
The back space (2) with lower depth is a closed space that houses the parts used to operate the system of the invention, whereas the front (3), which is open on the front, houses food containers (6) with parallelepiped structure inside horizontal compartments (5). In central position on the back wall of each container (6) a unidirectional valve is horizontally mounted (6a) to provide fast coupling with a pneumatic nozzle (4a) that protrudes on the front of the wall (4) that closes the front space (3) of the system (1 ) on the back.
To favor the sliding of each parallelepiped container (6) inside the corresponding compartment (5), the latter is provided in central position on the lower wall with a longitudinal groove (5a) adapted to cooperate with a rectilinear guide (6b) provided under the container (6).
It must be noted that the cooperation modes of the container (6) with the corresponding compartment (5) are such that an energetic thrust exerted on said container (6) from outside towards the inside also favors the stop of the entire container (6) perfectly inside the corresponding compartment (5), in addition to the coupling of the valve (6a) with the pneumatic nozzle (4a).
To extract the container (6) from the compartment (5), the user must simply exert a small thrust on the front of said container (6) to subject it to the thrust of a spring positioned between the back wall and the wall (4), which favors the uncoupling of the pneumatic nozzle (5) and pushes it shortly outside of the container (6).
Fig. 3 illustrates the structure and operation modes of the operational parts mounted inside said back space (2) of the system (1 ). The back space (2) houses a vacuum pump (7), a control and management unit (8), a pressure controller (9) connected with the pneumatic conduit (10) that connects said vacuum pump (7) with said pneumatic nozzles (4a) inserted in the wall (4).
When the user of the system (1 ) connects the valve (6a) of a container (6) with the corresponding pneumatic nozzle (4a), such a coupling is used to open said unidirectional valve (6a). In this way the pressure controller (9) that cooperates with said nozzle
(4a) detects the pressure drop along the conduit (10) caused by putting in communication the conduit (10) with the internal space of the container (6) when opening the valve (6a).
This information is immediately transmitted to the control and management unit (8) that is suitably interfaced with said pressure controller (9).
Accordingly, the unit (8) immediately activates the pneumatic pump (7) to generate vacuum inside the container (6).
When the pressure controller (9) detects the restoration of a set pressure value along the conduit (10), the unit (8) deactivates the pump (7).
As mentioned above, the extraction of the container (6) from the corresponding compartment (5), after uncoupling the pneumatic nozzle (4a), does not impair the vacuum condition because of the seal guaranteed by said unidirectional valve (6a).
