【Example】

 Referring to the figure, a refrigerator or freezer comprises a cabinet 1 including a normal refrigerating compartment and freezing compartments 2 and 3, said compartments having respective closing doors 4 and 5. The refrigerator comprises a vacuum pump 6, which is driven by an electric motor 7, from which a pipe 8 extends and terminates in an additional chamber 10 between the refrigerator compartment 2 and the freezer compartment 3. The pump is placed in a chamber 9 below the freezer compartment 3.

The chamber 10 is maintained at substantially 0 ° C. in a known manner and is connected to the refrigerating chamber 2 by a duct 11. The chamber 10 has its own door 12. The door connects to a support or basket 14 which slides on a guide 15 associated with the wall 16 of the chamber. As an alternative to this "pull-out" embodiment, the door can be hinged to the refrigeration cabinet 1.

A container 17 that creates a vacuum is removably placed in the basket. In detail, the container has a lower box part 18 which is hermetically closed with a lid 19. The box part 18 has a pipe (not shown) in the rear wall 22, which is connected to an adsorbing element (or adsorber) 23, which is arranged outside the part 18 and is known to it. Fix with the method. The duct opens into the free end 26 of the adsorber. The free end is arranged to cooperate with the plate 27 and the pipe 8 connected to the vacuum pump 6 opens into the plate through a suitable opening (not shown). The useful filter 27 is effectively associated with the plate 27.

According to a feature of the invention, the plate 27 is supported by an elastically deformable substantially L-shaped bracket 30, said L-shaped bracket being mounted on an element 31 arranged transversely above the container 17. It is fixed and fixed in a known manner to the wall 16 of the chamber 10.

In particular, the curved portion 32 of the bracket 30 supports the plate 27 on the side 33 facing the container 17 and on the opposite side a connecting element 35 for connecting to the pipe 8. An additional duct (not shown) is provided in the curved portion 32 for connecting the pipe 8 to the opening of the plate 27.

The bracket 30 supports a pin 37 that is fixed to a non-curved portion 38 that extends above the container. This pin projects from said portion 38 towards the container 17 and is arranged to cooperate with a preferably fork-shaped member fixed to the lid 19 when said container is inserted into the chamber 10. The pin 37 acts as a stop for this insertion.

Another feature of the invention is that the lid 19 laterally supports two elements or pins 40, which are cams or guide tracks on a panel 42 fixed to the wall 16 of the chamber 10. Sliding inside 41. Alternatively, the cams are provided on their own wall 16.

According to another feature of the invention, the traversed element supports a bracket-shaped support 45, the support projects from the element 31, and a first pin 46 is fixed to the support. To do. A first, for example, forked free end 47 of a substantially cylindrical member 48 is pivotally attached to each pin 46. The opposite free end 49 is connected to the second pin 50 fixed to the lid 19.

A compression spring 51 is provided around each member 48, the free end of which acts on the end element 52 of each member 48. The other end acts on the forked end 47 of the member. Finally (see FIG. 2), the gasket 55 located along the edge of the lid 19 has a first part 56 with two overlapping parallel plane parts (this part has a fork-shaped view in the sectional view of FIG. 2). Eggplant). The portion 56 is mounted on the edge of the lid. The gasket has a second part 57 which cooperates with the box part 18 of the container 17. Such a gasket provides a complete seal, prevents air from entering and leaving a complete vacuum in the container.

Other gaskets 60, 61 are provided on the wall 62 of the door 12 facing the front wall 1A of the refrigerator cabinet. In this case it is assumed that the door or drawer 12 is closed and the container 17 inside the chamber 10 is inserted therein and the adsorber 23 is in contact with the plate 27. At this time, if the vacuum pump 6 is driven (for example, by a normal push button on the front face 1A of the refrigerator cabinet 1), the suction force generated by the pump acts on the adsorber 23 through the pipe 8 and the adsorber ( Therefore, pull the container). The container is then placed in a basket 14 associated with the door 12. The door is completely closed to the refrigerator cabinet 1.

Due to the bracket 30 and its elasticity, excellent engagement can be obtained between the suction device 23 and the plate 27. After contact is obtained between the adsorber and the plate, a vacuum is established in container 17 as is known. If access to the container 17 is now required, pull the grip (shown at 12A in FIG. 2) provided on the door 12 to open it.

As the door pivots and opens, the container 17 (fixed to it) moves within the chamber 10. First, the adsorber 23 and the plate 27 are in contact with each other and associated with each other, the movement of the container causes the bracket 30 to bend, and this bending continues until the elasticity of the bracket returns it to its original position, so that the adsorber The separation between the plate and the plate occurs. Therefore, the vacuum in the container 17 is released. The absence of vacuum in the container means that the lid 19 separates from its box portion 18 as the door 12 continues to open.

This takes place by means of a pin or lateral element 40 sliding in a guide track 41. The track has the shape of guiding the element upwards (relative to the chamber 10), and as a result of the movement of the container 17, the lid 19 is lifted from the box part 18.

The lid moves with the box portion 18, but the adsorber 23 is still associated with the plate 27. In this condition, the member 48 pivots about the pins 46, 50, this pivoting continuing until its axis (the axis passing through the pins) is parallel to the transverse element 31.

When the adsorber separates from the plate 27 and the vacuum is broken, the member has already passed even a slight parallel position with the element 31 (known as the equilibrium position). At this time, the spring 51 acts by pressing the ends 47, 52 of the member 48, so that said member pivots around the pins 46, 50 and thus the lid 19 moves independently of the box part 18.

In this way, by completely opening the door 12 and pulling out the container 17 from the chamber 10, it is necessary to open the lid without being disturbed by the lid 19 remaining in the chamber 10. Without, a direct access to the part 18 of the container is possible. This is extremely useful, especially when the user's hands are constrained, as it allows easy access to the interior of the container.
