Description

Freezer with cold storage.

The invention relates to a freezer cabinet with a freezer enclosure arranged inside its housing heat-insulated within which several containers are provided arranged one above the other that can be removed from the enclosure freezer, as a drawer, to store products to freeze, where at least one of the containers serves to Receive cold accumulators.

It is known to store in devices refrigerators a few containers generally of form parallelepipedic, full of an eutectic solution, the so-called cold accumulators, and freeze the eutectic solution of these cold accumulators The cold accumulators cooled during the operating time of the freezer serves in first place to be able to maintain the proper temperature in the cold room for a certain period of time in the in the event of a power failure in the device, and prolong the heating time of the enclosure in this way refrigerator compared to a refrigerated enclosure that is not equipped with cold accumulators. Cold storage cooled also have the function of serving as elements chillers for cooling drinks or food products transported in a refrigerator bag. When a factory refrigerator cabinet, cold storage batteries they supply at the same time as an accessory in one of the drawer-like containers intended to receive products to freeze. The cold stores that are delivered together with the freezer are disposed loose in the container intended for them, or are subject within the space of container with additional fixing means. In the case of that are loose inside the container, the accumulators cold filled with liquid can move during transport of the refrigerator cabinet, for example, for the delivery thereof, of uncontrolled and unimpeded form due to accelerations and decelerations that act on them during the process of transport, which cannot exclude the possibility that cold accumulators, consisting mainly of a plastic container, may suffer deformation or damage. Yes additional fixing means are used to immobilize the cold accumulators inside the container space prevents the problem described above, if the fixation is correct, but instead additional fixing parts are needed that not only they suppose some additional costs of the pieces but also a additional time wasted to fix them. You also have to check provided that the fixing means are correctly anchored to hold the cold stores.

The invention aims to avoid the inconveniences of the state of the art in a freezer cabinet, according to the preamble of claim 1, with measures Simple constructive

This objective is achieved, in accordance with the invention, by the fact that the cold accumulators have of means that can act together with means of clamping provided in the container housing intended for fixing the cold accumulators inside the accommodation enclosure, largely for a positive adjustment and / or not positive

By using fasteners and clamping that act together, arranged by a party in the cold accumulators and on the other in the housing of the container, it is obtained for the accumulators of cold, without need for additional fixing parts, one fixing non-slip inside the housing of the container in a fast and economical way, since you can dispense with the anchoring of the cold accumulators inside of the housing enclosure using fixing parts additional.

The means and fasteners can be manufacture and assemble especially easily and in accordance with a preferred embodiment of the object of the invention it is foreseen that the means are made as accommodation or projections within which the fastening means can fit made as highlights or accommodations in the enclosure of container housing.

The accumulators of cold with the housings are they can manufacture especially easily and economically in large quantities, e.g. by deep drawing or similar yes, according to a following advantageous embodiment of the object of the invention, it is provided that the housings are made as recesses formed on the enveloping surface of The cold accumulators. Thanks to the means made in form of recesses a surface is also obtained that facilitates the handling of the cold storage batteries.

According to a following embodiment preferred object of the invention, with accumulators of cold made with a shape at least similar to a parallelepiped, it is planned that the recesses are formed in the two large opposite surfaces of the parallelepiped, the recesses located on one of the surfaces of the parallelepiped in the longitudinal direction of the parallelepiped, displaced in parallel with respect to the recesses located on the other surface of the parallelepiped.

In this way, the possibility of a different positioning of the accumulators of cold inside the container housing space, so that this can be used as needed in addition to the storage of products to freeze.

According to another embodiment preferred of the object of the invention is provided that one of the large surfaces of the parallelepiped present, in addition to the recesses, some protrusions in the form of busty, that are facing the recesses on the other surface of the parallelepiped, and be arranged in accordance with the subdivision and disposition of recesses

By means of cold accumulators formed by this way you get the possibility of stacking them on others saving space, leaving the accumulators of cold stacked and at the same time linked together anti-slip.

The cold stores are subject to especially safe, both individually and in disposition stacked, within the housing space of the container if, of according to another preferred embodiment of the object of the invention, it is provided that on each of the major surfaces of the parallelepiped are provided for at least four recesses, whose disposition and disposition of the highlights correspond each.

The recesses are made in a way especially advantageous if according to another embodiment advantageous of the object of the invention is that the recesses They are shaped like blind holes.

According to another embodiment preferred of the object of the invention is provided that the means clamping be formed at the bottom of the space accommodation.

In this way you not only get one especially economical and adequate manufacturing of means of support for large series in the consumer goods industry but at the same time an especially simple fixation of these, simply achieved by the accumulator's own weight of cold.

According to a last embodiment preferred of the object of the invention is provided that the means clamps are made as lugs that can fit in the surface recesses of the parallelepiped, being provided the breasts in two groups of four, next to each other in the bottom of the accommodation space.

In this way you have the possibility of being able to arrange at the bottom of the container, in a non-slip way, next to each other, the two cold accumulators provided generally to maintain the proper temperature inside of the freezer enclosure during a power outage, in order to take advantage of the space above for the storage of products to be frozen that have a large surface. To store refrigerated products of high format there is also the possibility of stacking the accumulators of cold over each other, so that the space next to it of them inside the container housing space be available for the storage of refrigerated products High format

By arranging the lugs in the bottom of the container accommodation space is created, in combination with the projections provided on one of the surfaces older than the parallelepiped, a unique correspondence for the Anti-slip arrangement of the cold accumulators in the inside the accommodation space, so that cold accumulators can be placed in the accommodation space directly in its correct position barriers.

The invention is explained in the description. following using an exemplary embodiment depicted of Simplified form in the attached drawing.

In this one you can see:

Figure 6 the cold store of Figure 5, in a perspective view from below, and

Figure 7 the cold store according to the figures 5 and 6 represented in section, according to the section line VII-VII of Figure 6.

According to figure 1 it is shown, in a simplified and partial schematic representation, an apparatus two temperature refrigerator 10 represented without door with a heated housing 11, in which there is a compartment refrigerator 12 and below it and separated by a wall intermediate heat exchanged 13 a freezer compartment 14. The freezer compartment 14 is equipped with containers for the products to be frozen 15 to 18 that can be taken out of compartment, like drawers, of which the container for the products to be frozen 18 located in the highest place, inside the freezer compartment 14, it is realized as what It is called a berry tray.

As can be seen especially in the figure 2, the container for the products to be frozen 18 is made one piece. The container for products to be frozen 18 which is manufactured, for example, as an injected piece of plastic, it has a housing 19 that is limited by container walls 20 and a container bottom 21. The container bottom 21 is provided with the lugs 20 directed to the inside the housing 19, which are made up of the same piece with the bottom of the container 21, and that in the In this case, they form two groups of four, I and II, located one next to each other parallel to each other, arranged in the form of a rectangle, whose vertices are determined by the studs 22. The projections 22 by way of lugs arranged in the two groups of four, I and II, serve for the non-slip positioning of 23 cold accumulators 23 made of plastic in the form of parallelepipeds, from preformed halves joined by welding. The cold accumulators 23 have a first face 24 large area of the parallelepiped with some recesses 25, which at just like the 22 studs are arranged in a group of four forming a rectangle, corresponding to the group of four, in as for its disposition, with the one of the projections 22 in the form of big tits In addition to the large surface area 24 of the parallelepiped, the cold store 23 has a second one in front of it face 26 of large area of the parallelepiped, which like the side 24 of the parallelepiped has recesses 27, arranged as groups of four as a rectangle. Displaced in parallel in the longitudinal direction they are provided on the face 24 of the parallelepiped, some protrusions 28 in the form of a stud, which at same as the recesses 27 on the face 26 of the parallelepiped are arranged as groups of four in the form of a rectangle, the projections 28 of the group of four being provided with a distance from each other equal to that of recesses 27, so that the arrangement of the projections 28 in the form of a brass corresponds to that of the recesses 27. The projections 28 are located directly above the recesses 25 of the face 24 of the parallelepiped.

As is especially apparent from Figure 2, two accumulators can be placed in the accommodation space 19 cold 23 ready, next to each other, being assured of non-slip form within the accommodation space 19, in a first arrangement variant, thanks to the joint action of the recesses 25 arranged on the face 24 of the parallelepiped with the corresponding projections 22 in the form of a stud at the bottom of the container 21.

In the case that because of the provision of the cold accumulators 23, as represented in the first arrangement shown in figure 2, it was no longer possible storage of a product to freeze high format in housing 19, due to lack of space existing now for the product to be frozen, you can stack one over another the cold accumulators 23 in a second variant of arrangement as can be seen in figure 3. For this purpose it is placed one of the cold accumulators 23 with its face 24 of the parallelepiped oriented towards the bottom of the container 21, on the face 26 of the parallelepiped of the other cold accumulator 23, with which the recesses 25 provided on the face 24 of the parallelepiped they can act together with the projections 28 located directly above, on the face 26 of the parallelepiped of the second cold accumulator 23. In this stacked position, the accumulators of  cold 23 overlap in a congruent position.

Another variant to stack the accumulators of cold 23 one on top of the other in the housing 19 you can see in figure 4. In this stacking process one of the cold accumulators 23 resting on the bottom of the container 21 as depicted in Figure 2, 180 ° around a vertical as well as 180º around a horizontal. TO continuation of this, the cold accumulator 23 removed from the bottom of the container 21 and rotated is placed in the bottom of the container 21 on the cold accumulator 23 resting in its position original. During this stacking process, the highlights 28 provided on the face 26 of the parallelepiped, of the accumulator of cold 23 lifted from the bottom of container 21 and rotated, fit in the recesses 27 provided on the face 26 of the parallelepiped of the second cold accumulator 23 resting on the bottom of the container 21, whereby the projections provided on face 26 of the parallelepiped of this again act in conjunction with the recesses 27 arranged on the face 26 of the parallelepiped of the cold accumulator 23 raised from the bottom of container 21 and turned. With this form of stacking of the cold accumulators 23, minimizes the height of stacking, since in the accumulator of cold 23 stacked in the upper position no protrusions 28, front faces facing each other other than cold accumulators 23.

Against the exemplary embodiment represented and described it is also possible to provide at the bottom of the container 21 instead of the studs 22 some recesses and shape corresponding, on the face 24 of the parallelepiped of the accumulator of cold 23, a few big tits 22 instead of the recesses 25.

In addition to this there is also the possibility of provide in the container 18 some clamping measures that can act with a positive or non-positive adjustment, for example, with some housings arranged on the front faces of the accumulators of cold.
