Description
- The present invention relates to a refrigerator provided with a refrigeration compartment containing a chamber for preservation at temperatures different from those of the compartment. Such a refrigerator is disclosed in US-A-4 793 145. In the refrigeration compartment of refrigerators, it is known to provide a chamber, known as a crisper, for containing vegetables, fruit or other food to be preserved at a temperature higher than that in the rest of the compartment.
- Relatively frequently, this chamber has a volume insufficient to contain those vegetable and fruit quantities which satisfy the requirements of a normal family, especially during periods of particular availability and cheapness.
- Even a single conventional packet of salad or spinach occupies most of the crisper so that the remaining free part is inadequate for containing other different but likewise voluminous packages (for example of carrots, courgettes, peppers, peas or aubergines), without even considering melons and water melons. It is true that to avoid excessive damaging compression within the crisper, the user can solve the problem by locating the excess packages or products on the refrigerator shelves, however in this situation they are preserved under unsuitable temperature conditions, such as to negatively affect the preservation and organoleptic characteristics of the preserved food.
- From-the aforegoing it is clear that under certain conditions the user requires the availability of chambers of greater capacity which are still at a temperature different from that of the refrigeration compartment and more suitable for preserving specific types of food.
- The main object of the present invention is therefore to provide a refrigerator with a chamber able to satisfy the said user requirement.
- This requirement is satisfied by a refrigerator in accordance with the teachings of the accompanying claims.
- The invention will be more apparent from the ensuing detailed description of some preferred embodiments thereof provided by way of non-limiting example and illustrated in the accompanying drawings, in which:
- Figure 1 is a schematic partly sectional view of the lower region of one embodiment of the refrigerator of the invention, this region being concerned in the invention;
- Figure 2 is a more constructional perspective partial view of the aforesaid region relative to the same embodiment of the invention;
- Figure 3 is a schematic transparent perspective view of the same embodiment;
- Figure 4 is a view similar to that of Figure 3 but showing another embodiment of the invention;
- Figures 5A and 5B are schematic views taken from different angles of the embodiment of Figure 4, shown in two different positions of use;
- Figure 5 is a schematic perspective view of a third embodiment of the invention.
-
- With reference to the first three figures, the
reference numeral 1 indicates the lower part of a refrigerator. - The refrigerator comprises a conventional refrigerated
preservation compartment 2, bounded by the door (not shown), byside walls 3, by arear wall 3A, by abottom wall 3B and by a top wall (not shown). At predetermined heights, each of itsside walls 3 presents projecting support elements or supportingshelves wall 3 is, for support purposes, coplanar with one on the other opposite wall. The consecutivelowest pairs - The invention provides a removable structure, to rest on one or the other of the pairs of
support elements support elements 4B, or by 5' if resting on theunderlying support elements 4A. - This removable structure defines, or rather serves to delimit, together with the
walls refrigerator preservation compartment 2, two chambers of different capacities, the smaller of which applies when the structure in question rests on theelements 4A. - To visualize these capacities, of which the larger incorporates the smaller, this latter is defined by dotting and the larger by crosses.
- The refrigerator hence comprises a chamber of variable volume, which depends on the location of the structure.
- The
structure 5, 5' (shown in Figures 1, 2, 3) comprises a glass plate 6 (which always acts as the upper wall independently of its capacity) surrounded by aplastic frame 7, which on the interior of the twosides slide guides 8 for the so-called "door" of the chamber and which in the specific example is similar to aroll shutter 10 which can consist of a plurality of bars, for example of plastic material, hinged or pivoted to each other. - The structure in question presents at its front, substantially as an extension of each
side 7A, 78, a telescopicallyextendable leg 9 the components of which are indicated by 9A and 98, saidslide guides 8 extending longitudinally into these components via aconnection region 11, to enable theroll shutter 10 to be slid along thelegs 9 and hence close the front of the chamber when in either possible capacity, or to open it by movement in the opposite direction. - To use the smaller chamber capacity, the
telescopic legs 9 are set in their retracted position and the structure is placed with itsframed plate 6 on thelower support elements 4A; in Figure 1 the structure is indicated with this capacity by 5'. When the user requires a larger capacity the structure is supported on theupper support elements 4B (as indicated by 5) and thelegs 9 are extended. - The legs can be removably retained in their retracted position by any known releasable catches, possibly elastic (Figure 1 shows a catch operating member, indicated by 12.
- Figures 4, 5A and 5B (in which equal or corresponding parts are indicated by the same reference numerals plus an apostrophe) show a refrigerator with a variable volume chamber obtained by means of a structure which differs from that of the preceding figures in that the
telescopic legs 9 are lacking and the movable wall for closing and for gaining access to the interior of the chamber (which in the preceding figures is represented by the roll shutter 10) is here replaced by twopanels panel 21 is provided with a suitable surround and is hinged at 22 to the front side of the frame 7' of the cover plate 6'. - The
panel 21 is provided at its sides withslide guides 23 for thepanel 20. - In a manner similar to the aforestated, the removable structure is rested with its cover plate 6' on the conventional support elements, here not shown, provided on the side walls of the refrigerator.
- The support elements selected are those which correspond to the capacity required by the user. Figures 4 and 5B represent the structure position for providing the larger capacity, whereas Figure 5A represents that for the smaller capacity. When in the larger capacity position, the two
panels panel 20, by virtue of its ability to be slid along theguides 23, is superposed on thepanel 21. When the user requires access to the chamber interior, he rotates the twopanels hinge 22. - Figure 6, in which parts equal or corresponding to those of the preceding figures are indicated by the same reference numerals plus a double apostrophe, shows a structure similar to that of Figures 4, 5A, 5B, the only difference being that the two
panels 20". 21" are hinged together at 24, in the manner of a book. When in the smaller capacity position the two panels are superposed by rotation about the hinge 24 (and can be retained thereat for example by magnets and counter-magnets or conventional temporary retention means positioned in walls forming total or partial surrounds about the twopanels 20" and 21"). - When in the larger capacity position the two panels are both used to close the chamber. The function of the
hinge 22" is to enable the two plates to be rotated for access to the chamber, as indicated in the preceding embodiment. - The
framed plate structure 5, 5' presents at one end approximately hook-shaped means 30, 30" to cooperate, for suitable longitudinal retention of thestructure 5, 5', with counter-means provided at thesupport elements
