Definitions
- the present invention relates to a refrigerating apparatus according to the preamble of the first claim appended hereto.
- Prior-art refrigerating apparatuses often comprise a plurality of refrigerated cells or chambers operating at different temperatures.
- Another problem of known household refrigerating apparatuses arises when a user must, for example, unfreeze a food, or more in general a product, so that it can be used.
- the user will first have to open the freezer cell where the food is stored, remove the product from the freezer and put it in a suitable place, keeping it there until it is unfrozen (all this must be done a few hours before meal time).
- the present invention is based on the idea of providing a refrigerating apparatus comprising at least a first chamber and a second chamber operating at different temperatures, wherein the two chambers are adjacent to each other and are separated by at least one movable thermoinsulating wall, and wherein the apparatus comprises moving means for moving a product at least from the first chamber to the second chamber.
- one of the two chambers is a freezer cell and the other one is a defreezer cell, which allows the user to let the foods unfreeze inside the refrigerating apparatus itself, without having to use other kitchen cabinets.
- the moving means may be servo-assisted and remotely controllable, e.g. through an Internet connection, a mobile telephone or the like, thus allowing the user to defreeze a product even when he/she is distant from the refrigerating apparatus.

- Fig. 13 shows a first alternative embodiment of the variant of Fig. 11;
- Fig. 14 shows a second alternative embodiment of the variant of Fig. 11;
- Fig. 15 shows a modular refrigerating apparatus according to the present invention
- Figs. 16-18 show a module for the refrigerating apparatus of Fig. 15.
- a refrigerating apparatus 1 equipped with refrigerated cells which are kept at refrigerator temperature, which is normally around 3 or 4°C, and at freezer temperature, which is normally -12°C or lower, preferably -18°C; the refrigerating apparatus 1 is preferably of the so-called "no-frost" type, wherein cell cooling is provided by air conveyed by fans into thermal exchange contact with a cooling coil and then delivered into the refrigerated cells.
- Said refrigerating apparatus comprises at least one refrigerator compartment and one freezer compartment.
- the refrigerator compartment may comprise internally a separator element which can be positioned at different heights to implement an energy saving functionality in the presence of a smaller load than the rated one, said functionality following the teachings of patent application EP2182310.
- the door 2 on the front side of the refrigerating apparatus 1 allows access to the region of the latter shown in detail in Fig. 2.
- first chamber 3 In this region there are a first chamber 3 and a second chamber 4, separated by a movable thermoinsulating wall 5.
- the two chambers are kept at different operating temperatures; preferably, the chamber 3 is a freezer cell, and is therefore kept at a temperature equal to or lower than
- the second chamber 4 is a defreezer chamber, and is therefore kept at higher temperatures ranging between 5°C and 60°C, preferably between 25°C and 40°C.
- the temperature in the first chamber 3 can be maintained through the cooling system of the refrigerating apparatus 1, whereas the temperature in the second chamber 4 can be adjusted by means of an adjustment system which comprises temperature sensors, a control unit, ducts opening into the outside environment, cooling ducts and possibly also electric heating resistors.
- the adjustment system control unit keeps the chamber 4 at temperatures suitable for defreezing foods, from time to time activating the various temperature adjustment devices as necessary, such as electric heating resistors (which can raise the temperature in the chamber 4 up to 60°C) arranged in neighbouring locations with respect to the second chamber 4, but with the least possible interference with the first chamber 3.
- the various temperature adjustment devices such as electric heating resistors (which can raise the temperature in the chamber 4 up to 60°C) arranged in neighbouring locations with respect to the second chamber 4, but with the least possible interference with the first chamber 3.
- the wall 5 is thermo insulating because it must allow the temperature difference between the adjacent chambers 3 and 4 to be maintained without wasting energy.
- FIGs. 2 and 3 there are shown the moving means that allow moving a product from the first chamber to the second chamber without the second chamber being exposed to the outside environment.
- said moving means have a number of specific features.
- both chambers 3 and 4 are housed in a drawer 6, which can be extracted wholly or partially from the cabinet 7 of the refrigerating apparatus 1.
- the freezer chamber 3 (or in general the one of the two chambers 3 and 4 which is kept at a lower temperature) is farther away from the door 2, which in this example constitutes the front wall of the drawer 6.
- This feature allows the user to gain access to the chamber 4 (at a higher temperature) without necessarily having to open the chamber 3 to the outside environment (at a lower temperature): when the drawer 6 is extracted partially, in fact, the front chamber 4 opens to the outside environment, but the rear chamber 3 stays inserted in the cabinet 7 without getting in contact with the air of the outside environment, which is normally warmer and more humid.
- retaining means may be provided which can be deactivated by the user and which stop the movement of the drawer 6 in a position where only the chamber 4 is outside the volume of the refrigerating apparatus 1.
- the moving means comprise the thermoinsulating wall 5 itself, which is shaped like an "L”, as shown in Figs. 2 and 3, and is rotatable about a horizontal axis coinciding with a rotation pin 8 adjacent to the bottom of the drawer 6.
- the movable wall 5 extends at least partly horizontally and constitutes at least a portion of the bottom of the first chamber 3 or the second chamber 4, depending on its position.
- the movable wall 5 comprises two perpendicular branches having the same length, between which a product container 3 can be housed, so that said container 9 can be transferred from the first chamber 3 to the second chamber 4 when the wall 5 is turned.
- the containers 9 can be removably associated, through suitable housings, with the wall 5 between its two perpendicular branches, so that the container 9 can be brought from the first chamber 3 to the second chamber 4 (and vice versa) simply by turning the wall 5 about its horizontal axis.
- the wall 5 is moved automatically, e.g. by means of an electric motor selectively acting upon the pin 8 and controllable from a suitable interface or remotely through a data connection line (whether wired or wireless): the user can thus control the rotation of the wall 5 (and hence the movement of the product containers 9) by operating the interface or a remote control terminal even without physically accessing the apparatus 1 and without opening the drawer 6.
- Said remote control terminal may be a portable telephone, a computer or the like, or, more simply, a control interface arranged externally to the apparatus 1, e.g. on the cabinet 7 thereof.
- Fig. 3 As regards the wall 5 and the containers 9 associable therewith, reference will now be made to Fig. 3: as can be seen, the wall 5 is subdivided into a plurality of vertical sectors 5 A, 5B, 5C, each rotatable independently of the adjacent one.
- Each vertical sector 5A, 5B, 5C is also shaped like an "L" and is associated with a respective container 9A, 9B, 9C.
- the user thus can, either manually or in a servo-assisted manner, select the container to be moved from the first chamber 3 to the second chamber 4 (or vice versa), while leaving the positions of the other containers unchanged, simply by acting upon the vertical sector 5A, 5B, 5C associated with the container 9A, 9B, 9C that contains the product to be moved.
- An example of such an operating situation is shown in Fig. 3 in its different actuation steps: from an initial condition wherein all containers are positioned on the same side of the wall 5, turning the vertical sector 5C leads to a condition wherein the container 9C is positioned on the opposite side with respect to the other containers.
- each vertical sector 5A, 5B, 5C there are gaskets the function of which is to prevent or limit heat losses to the adjacent vertical sector and upwards.
- the pin is articulated, and even only portions thereof, corresponding to respective containers, can be rotated.
- each container is associated with the pin through a hinge, so that it can be turned while leaving the positions of the other containers unchanged.
- containers 9 can be of different typologies 9', 9" e 9" ', as shown by way of example in Figs. 4-10.
- Figs. 4-7 show a first typology 9' which is particularly suited to containing solid products, such as meat or fish portions.
- the container 9' comprises side walls 91 made of food-grade silicone which are secured to a perimetral frame 92, e.g. made of rigid plastic.
- the side walls 91 may be elastic to allow the container to be filled with solid food which is then kept compressed between the walls, thus preventing it from accumulating by gravity on the bottom of the container 9' when it is not yet frozen.
- the perimetral frame 92 is made up of two symmetrical halves, each associated with a corresponding side wall 91, which can be closed one onto the other so that the container 9' can be opened by simply separating the two halves.
- the container 9 comprises a support box 93 that houses removable containers 94, which can be closed with a cover so that they can be filled with a liquid and left to freeze.
- a third container typology 9" ' suitable in general for various types of food, is the one shown in Fig. 10: it comprises a box 95 which can be closed by a horizontally-pivoted cover 96.
- Figs. 11 and 12 show a detail of a variant 10 of the refrigerating apparatus.
- the first chamber 30 is arranged on top of the second chamber 40, and the two chambers are separated by the movable thermo insulating wall 50, which separates the first chamber 30 horizontally from the second chamber 40 and which is rotatable about at least one horizontal axis when pushed downwards by the weight of a container 90, so as to allow the latter to pass from the first chamber 30 to the second chamber 40.
- the movable wall 50 forms at least a portion of the bottom of the first chamber 30 and is separated into two parts, each secured to an inner wall of the refrigerating apparatus and rotatable about a horizontal axis, so that it can be opened downwards like a trap door, i.e. towards the second chamber 40, as shown in Fig. 12.
- the characteristics relating to the operating temperatures (as well as to the obtainment and maintenance thereof) of the first 30 and second 40 chambers, are similar to those of the chambers 3 and 4 of the above-described example and will not therefore be discussed any further.
- the products (or foods) preserved in the first chamber 30 are contained in containers 90 which can be removably secured to one of the inner walls of the first chamber 30, in particular to the top wall of the first chamber 30.
- this removable fixing takes place by means of permanent magnets placed on the container 90, which cooperate with electromagnetic bases arranged on the inner wall of the first chamber 30: when the electromagnetic base is de-energized, the magnetic attraction force that holds the container 90 against the vertical wall is lost; the container 90 will then fall by gravity onto the movable wall 50 and, due to its weight, will cause it to open towards the second chamber 40 and let the container 90 fall into the latter.
- the movable wall may be provided with elastic elements, such as springs or the like, allowing it to return to the position in which it closes the passage between the two chambers 30 and 40 when the container 90 is no longer resting on the wall 50.
- an alternative embodiment 100 of the variant illustrated in Figs. 11 and 12 is the one shown in Figs. 13 and 14.
- the first chamber 300 extends all around the second chamber 400, and the movable thermo insulating wall 500 is made as one piece.
- the system operates by gravity, since the container 900 gets detached and falls onto the wall 500, thus causing the latter to rotate towards the inside of the chamber 400 until the container 900 slides down into it; an elastic element, e.g. a spring, will then bring the wall 500 back to its original position, thus separating again the two chambers 300 and 400.
- an elastic element e.g. a spring
- Both the variant of Fig. 11 and the alternative embodiment thereof shown in Fig. 13 use gaskets on the edge of the movable wall 50, 500 in order to improve the thermal insulation between the two chambers 30,300 and 40,400, which operate at temperatures that may differ by up to 80°C.
- the movable wall 5,50,500 may advantageously comprise a layer of highly thermally insulating material, such as aerogel (which is a per se known material and will not therefore be described any further) and/or a vacuum layer.
- a layer of highly thermally insulating material such as aerogel (which is a per se known material and will not therefore be described any further) and/or a vacuum layer.
- the refrigerating apparatus may advantageously be equipped with a control unit including a timer and/or a clock, which can be put in communication with a local user interface (e.g. applied to the apparatus itself) and/or a remote user interface (e.g. a mobile telephone, a computer or other similar devices).
- a local user interface e.g. applied to the apparatus itself
- a remote user interface e.g. a mobile telephone, a computer or other similar devices.
- the user can receive information about the products contained in the freezer compartment, i.e. type, remaining or elapsed preservation time, quality, quantity, best-before date or other information.
- Such information may be entered into a memory unit of the refrigerating apparatus through a user programming procedure to be executed when the user puts the products into the containers, or it may be contained in suitable labels applied to the products or to the containers, e.g. bar code labels or RFID (Radio Frequency IDentification) tag labels, which are per se known and will not therefore be discussed any further herein; in this case, the refrigerating apparatus must comprise a radio frequency scanner suitable for this purpose. Thanks to this information (specifically, product quality and quantity), the apparatus control unit can calculate the defreeze time of each product in each container.
- suitable labels applied to the products or to the containers e.g. bar code labels or RFID (Radio Frequency IDentification) tag labels, which are per se known and will not therefore be discussed any further herein; in this case, the refrigerating apparatus must comprise a radio frequency scanner suitable for this purpose. Thanks to this information (specifically, product quality and quantity), the apparatus control unit can calculate the defreeze time of each product in each container.
- RFID Radio Frequency
- control unit When the user selects a product through the interface, the control unit will calculate, based on said information, the time required for defreezing the product and will tell the user when the product should be ready, if the defreezing process is started immediately by moving the product from the freezer chamber to the defreezer chamber as taught above.
- control unit will calculate the defreeze time and control the transfer of said product from the freezer chamber to the defreezer chamber in a manner such that at the time selected by the user the product will have just been unfrozen and will be ready for being cooked or eaten.
- control unit can provide the user with all product-related information by sending it to the control interface, whether local or remote, so that the user has the possibility of checking the frozen products, the defreeze times, the best-before dates and other information, thus being able to properly handle the steps necessary for preparing, preserving and supplying foods.
- the method comprises the steps of:
- step c d- calculating the time necessary for defreezing said selected product based on the information retrieved in step c
- the removable fixing obtained through magnets and electromagnetic bases may be replaced with mechanical servo-assisted couplings, which can disengage the container
- Such mechanical couplings may comprise, for example, a hook constrained to the container
- hooks may be applied to a side wall of said first chamber, the profile of which is complementary to connection means obtained on said container.
- the present invention is applicable to modular refrigerating apparatuses, i.e. refrigerating apparatuses having one or more specialised compartments used for additional functions, which can be customised according to the user's needs and wherein the temperature can be automatically adjusted as a function of such customisation.
- FIGs. 15 to 18 A refrigerating apparatus of this type is shown in Figs. 15 to 18.
- the refrigerating apparatus 10 comprises two modular compartments, one of which houses a device D for the preparation of vegetables in general, whereas the other one houses a freezer/defreezer module as previously described.
- the device D comprises two compartments 51 and 52 placed one on top of the other and having a substantially coinciding plan shape; the upper compartment is intended for containing vegetables, preferably leaf vegetables such as salad and the like.
- the upper compartment may optionally be subdivided into multiple sectors, e.g. the sectors 51 A, 5 IB and 51C, by means of corresponding vertical septa.
- a water dispenser (not shown), intended for letting a certain quantity of water drop onto the vegetables stored in the upper compartment in order to wash them.
- Each sector of the upper compartment can be run by a corresponding thrust piston 55 (the drawing only shows one) or, as an alternative (when the upper compartment is not subdivided into multiple sectors), a single piston 55 moves vertically up and down in the compartment 51 to push downwards the vegetables contained therein.
- a passage which can be closed by a removable bottom wall and which can be intercepted by one or more rotary blades 56 rotating about a vertical axis.
- the lower compartment 52 is rotatable about a vertical axis and comprises a grid 57 arranged horizontally over the bottom wall.
- the system operates as follows: the user places vegetables into the upper compartment through a suitable access opening (not shown); the vegetables rest on the removable bottom wall, which is in the condition wherein it intercepts the passage between the upper compartment 51 and the lower compartment 52.
- the dispenser then sprays the vegetables with water (to which a hygienisation agent may have been added), thus washing them.
- the removable bottom wall is then moved, and the piston 55 and the rotary blades 56 are actuated; the piston 55 pushes the vegetables into the passage intercepted by the rotary blades 56, which cut the leaves into smaller pieces, e.g. suitable for preparing a salad.
- the cut vegetables then falls by gravity into the lower compartment 52, where it rests on the grid 57.
- the lower compartment 52 is rotated and any water drops remaining on the vegetables are removed by centrifugal force: in fact, they get detached from the vegetables through the effect of centrifugal force and accumulate onto the side walls of the lower compartment 52; from there, they glide downwards and gather into the space between the grid and the bottom wall of the lower compartment 52.
- the user can then pick up the cut and dried vegetables directly from the lower compartment 52, which for this purpose is fitted with a reclosable access opening (not shown).
- modules may be installed in the refrigerating apparatus 10, such as, for example, an ice-cream module or dispenser modules for dispensing fruit-juice or yogurt preserved at controlled temperatures.
