Definitions
- the present invention relates to a refrigerating appliance according to the preamble of the first claim, and typically applies to freezers and refrigerator-freezers, in particular to upright no-frost freezers, used for preserving and/or storing foodstuffs.
- the term “freezer” refers to refrigerating appliances operating at temperatures below 0 °C, preferably between -5 °C and -30 °C; furthermore, the term “no-frost” refers to refrigerating appliances wherein foodstuffs cooling is ensured by cold air conveyed into the refrigerating cell by a forced ventilation system; the circulating air is cooled by an evaporation-type exchanger, or evaporator, by thermal exchange with a colder refrigerating fluid.
- the section through which the user can reach inside the refrigerating cell is a vertical one.
- the freezer and its refrigerating circuit are nonetheless sized for the heaviest operating conditions, which implies that they are not sized appropriately for small loads in the refrigerated compartment.
- the refrigerating apparatus described therein comprises a compartment provided in its upper region with a cold air inlet duct and a removable insulating wall, which is inserted into the compartment in order to subdivide it into two distinct chambers; each chamber includes drawers located at a distance from one another and from the back wall of the compartment, so as to create interspaces for the circulation of the cold air flow coming from the upper lamellar pack.
- the insulating wall is inserted, the air flow within the refrigerating apparatus is stopped and only the upper chamber is cooled.
- a drawback of this solution is that when no drawers are placed in the apparatus it is not possible to obtain a proper air circulation in the chambers: in fact, if the chambers are empty, no air will be directed into the interspaces provided between the drawers, so that the air will follow a random path within the chamber without ensuring a homogeneous cooling effect.
- the present invention aims at improving this state of the art by providing a refrigerating appliance consisting of a freezer or a refrigerator-freezer characterized by features that allow to reduce the energy consumption when the load conditions of the appliance change, while at the same time also being flexible to use because it can be used without distinction in a configuration with drawers or in a configuration without drawers.
- the object of the present invention is a refrigerating appliance equipped with compartments cooled by cold air produced by an evaporator and conveyed into the compartments through a distribution duct communicating therewith and housing at least one flow regulator capable of intercepting the cold air flow in order to cool one or more compartments.
- a freezer 1 in particular an upright freezer, the inner space of which is subdivided into two compartments 2, 3 separated by a separator wall 4 made of insulating material, e.g. polystyrene, polyurethane foam or the like.
- insulating material e.g. polystyrene, polyurethane foam or the like.
- Separator wall 4 may appropriately consist of a fixed component of freezer 1; as an alternative, it may be a removable component of freezer 1, so that it can be cleaned more easily.
- a condensate collector (not shown because per se known) connected through a drain tube to a basin arranged above the compressor, for discharging any condensate that may form on the separator wall.
- Two compartments 2, 3 may be accessible to a user by means of either a single door 20 or two distinct doors.
- each compartment 2 and 3 houses drawers 5 of a per se known type, which are adapted to contain foodstuffs; compartments 2, 3 may however accommodate no drawers, but be fitted, for example, with shelves for supporting the foodstuffs, without any detriment to the operation of the refrigerating appliance according to the present invention, as will be explained below.
- Freezer 1 is of the no-frost type, in accordance with the meaning provided above: for this purpose, it comprises an evaporator 6 included in the refrigerating pack, which cools an air flow produced by a fan 8.
- a distribution duct 7 provided in the form of a walled canalization at the back wall of the cell.
- the distribution duct consists of an interspace adjacent to back wall 16 of the cell which is in fluid communication with compartments 2 and 3 through apertures 11 and 11A.
- Flow regulator 9 is equipped with a shutter 10 which, in the example shown in Figs. 1 and 2 , consists of a bulkhead rotating about an axis perpendicular to duct 7, thereby intercepting the port of the duct so as to either stop the cold air flow or allow it to pass from upper section 71 to lower section 72 of distribution duct 7.
- flow regulator 9 consists of an electromechanical valve commonly known as "damper", i.e. a bulkhead that can rotate about an axis, as shown in Figs.
- a “damper” may be included in separator wall 4, said separator wall 4 being mechanically connected to distribution duct 7 in a manner such that the damper can act upon distribution duct 7 in order to open and/or close a section thereof.
- the "damper” is an advantageous example of an actuator which can be controlled electronically in a very simple manner.
- Separator wall 4 is illustrated in more detail in Fig. 13 , and may comprise at least one region also equipped with a flow regulator 90, similar for example to flow regulator 9 and adapted to allow cold air to flow along its return path 50 towards evaporator 6, which region will be described in more detail later on.
- a flow regulator 90 similar for example to flow regulator 9 and adapted to allow cold air to flow along its return path 50 towards evaporator 6, which region will be described in more detail later on.
- the cold air flow produced by fan 8 is conveyed into distribution duct 7, and from there it is distributed homogeneously into compartments 2 and 3 through apertures 11 and 11A, respectively.
- flow regulator 9 can also be actuated for closing the section of duct 7 only partially: by varying the degree of opening of flow regulator 9, the flow rate of the cold air conveyed into compartment 3 is changed accordingly, resulting in a temperature variation within that compartment.
- Flow regulator 90 arranged on wall 4 is controlled in the same manner as flow regulator 9 of distribution duct 7: when the latter closes duct 7, flow regulator 90 is also controlled for closing air return path 50, in order to insulate the two adjacent compartments thermally. Likewise, flow regulator 90 may also close or open the air passage section partially.
- control and actuation units may be either built in, e.g. when the flow regulator is actuated manually, or separate, e.g. when the shutter is actuated by a drive unit such as an electric motor, which is controlled by a control element such as a push-button or a lever that can be operated by a user.
- the air circulation in the freezer is illustrated through downward-pointing arrows in duct 7 and upward-pointing arrows (which designate a return path 50 in which flow regulator 90 of separator wall 4 is located) alongside door 20: the air, cooled by evaporator 6, is pushed by fan 8 into upper section 71 of duct 7, and then enters duct 2 through apertures 11; if flow regulator 9 is open, the remaining cold air flow is pushed downwards into second section 72 of duct 7 and enters lower compartment 3 through corresponding apertures 11A.
- return path 50 comprises an interspace obtained between separator wall 4 and the door's inner panel; in another embodiment which is more efficient from the energetic point of view, said interspace is kept to a minimum and return path 50 comprises a canalization obtained within separator wall 4 and adapted to put compartment 3 in communication with compartment 2.
- flow regulator 9 When only the upper compartment 2 must be cooled, flow regulator 9 is closed in order to stop the downward-directed cold air flow, and also flow regulator 90 is closed in order to prevent any thermal dispersion towards compartment 3, which requires no cooling.
- duct 7, which is distinct from compartments 2 and 3, is preferably arranged behind back wall 16 of said compartments, which is opposite to door 20, thus improving the compactness of freezer 1.
- Figs. 3 to 6 show some different types of flow regulators which are especially advantageous when housed in duct 7.
- a first type of regulator which is light, inexpensive and easy to install is the one illustrated in Figs. 3 and 4 in its two operating conditions (closed and open), i.e. a grid-type flow regulator 9'.
- the latter is made up of two overlaid grids 10'A, 10'B which can translate parallel to each other, so as to open or close the air passage (for simplicity, the air flow is indicated by arrows in Figs. 3 and 4 ); in this case, the flow regulator may be actuated simply and effortlessly by a user's hand.
- FIG. 5 Another type of flow regulator 9" is illustrated by way of example in Fig. 5 : in this case, the flow regulator simply consists of a slide 10" that slides perpendicularly to the axis of duct 7, so as to interrupt the continuity thereof; in this case as well, the flow regulator can be manufactured easily and economically.
- flow regulator 9"' is a butterfly unit which comprises a shutter 10'" of the same size as duct 7 in which it is inserted, which can rotate about an axis perpendicular to the axis of the duct 7, and which, in the embodiment illustrated herein by way of example, is fitted with actuation units 15 such as, for example, a direct-current electric motor that can be controlled by a user through a push-button or the like; motor 15 shutter 10'" to rotate, thus opening or closing the port of duct 7.
- actuation units 15 such as, for example, a direct-current electric motor that can be controlled by a user through a push-button or the like; motor 15 shutter 10'" to rotate, thus opening or closing the port of duct 7.
- These types of flow regulators in particular the grid type 9', may also be used on wall 4 by arranging them along the air return path 50 to the evaporator 6, and therefore preferably in the front region of wall 4 near the door, as shown in Figs. 8 and 13 .
- FIGs. 1 and 2 show a freezer 1 having only two compartments 2 and 3, it is nonetheless possible to apply the teachings of the present invention more in general to a refrigerating apparatus comprising three or more compartments cooled by cold air conveyed thereto through a distribution duct in fluid communication therewith, which houses at least one flow regulator for intercepting the cold air flow in order to cool one or more compartments.
- FIG. 7 illustrates a no-frost refrigerating appliance 1' with three compartments 21, 22 and 23, in which a distribution duct 7 conveys into compartments 21, 22 and 23 the cold air produced by a heat exchanger and pushed by a fan; the compartments have different volumes, and while compartments 21 and 23 are provided with drawers 5, remaining compartment 22 has no drawer, without any detriment to the operation of the appliance: in fact, the cold air is supplied to compartments 21, 22 and 23 through apertures 11, 11A and 11B, respectively; compartments 21, 22 and 23 are separated by separator walls 4 and 40 similar to separator wall 4 described above.
- distribution duct 7 is subdivided into three sections 71, 72 and 73, which communicate with compartments 21, 22 and 23, respectively, through apertures 11, 11A and 11B; along duct 7, between different sections 71, 72 and 73, there are two flow regulators 9 and 99 as described above; refrigerating apparatus 1' operates in the same way as well, with the only difference that by controlling flow regulators 9 and 99 a user can choose whether to cool all the compartments or only two of them, i.e. intermediate compartment 22 and upper compartment 21, or alternatively only upper compartment 21, depending on the quantity of foodstuffs stored therein.
- the separator walls are equipped with flow regulators 90, the latter will also close accordingly in order to insulate the cooled compartment(s) thermally from the uncooled compartment(s), or from those compartments which are cooled differently, as will be described below.
- flow regulator 90 may be omitted, with the only drawback of a slight thermal insulation loss when either one of two compartments 2, 3 is left uncooled, but to advantage in terms of production costs of the refrigerating appliance.
- the refrigerating appliance may even have no drawers, as shown in Fig. 8 ; for example, it may alternatively be fitted with shelves without any operational drawback.
- duct flow regulator 9 and/or wall flow regulator 90 are equipped with electric actuation units, it is conceivable to control them by using the information acquired by sensors 30 and 31, in particular by sensor 31 (preferably consisting of a temperature sensor) located in compartment 3, the cooling of which depends on the opening of distribution duct 7 by flow regulator 9, as a function of user-defined parameters (such parameters comprising, for example, a Boolean indicator attesting whether the user wants to use compartment 3 or not, or the desired temperature value within compartment 3, e.g. a simple two-position button).
- sensor 31 preferably consisting of a temperature sensor located in compartment 3
- the cooling of which depends on the opening of distribution duct 7 by flow regulator 9 as a function of user-defined parameters (such parameters comprising, for example, a Boolean indicator attesting whether the user wants to use compartment 3 or not, or the desired temperature value within compartment 3, e.g. a simple two-position button).
- the refrigerating apparatus comprises a control panel communicating with at least sensor 31 and the actuation units, and having a user interface through which it can set those parameters depending on which, once a certain temperature threshold has been detected by sensor 31, the actuation units either open or close distribution duct 7, or alternatively increase or decrease the air passage cross-section (as described above), so as to adjust the cold air flow rate and consequently the temperature in compartment 3.
- distribution duct 7 may be a simple canalization having any cross-section; for example, in Fig. 9 distribution duct 7' consists of an interspace behind wall 16 provided with an aperture 11C, in Fig.
- the duct 7" is a circular-section tube arranged behind back wall 16 and communicating with the compartments through outlets 11D
- duct 7' is a trapezoidal-section tube arranged behind back wall 16 and communicating with the compartments through outlets 11E
- duct 7"" is a circular-section tube arranged in front of back wall 16 (i.e. within the cell of the refrigerating appliance) and communicating with the compartments through outlets 11F (duct 7"" may of course have a square, rectangular or trapezoidal cross-section).
- flow regulators 9 and/or 99 of the distribution duct are respectively secured to separator walls 4,40 on the side thereof that faces duct 7 in the assembled condition: in this case, duct 7 has a hole in which flow regulator 9 is inserted as shown in Fig. 14 , wherein the flow regulator is a grid-type flow regulator 9' integral with separator wall 4 and inserted in the hole of duct 7.
- grid-type regulator 9' is preferable because it is very easy to install and can be interfaced at best with non-circular ducts, as is the case when duct 7 is provided as an interspace or as any non-circular-section duct (as described above). Should control efficiency have to be privileged over installation simplicity, grid-type regulator 9' may advantageously be replaced with a "damper" of the above-described type.
- walls 4, 40 are fixed, tests have shown that it is advantageous to provide a volume distribution such that, for an appliance with two compartments like the one shown in Figs. 1 and 2 , the upper compartment takes up about 60% of the total inner volume, while the lower compartment takes up the remaining 40% of the total inner volume.
- walls 4, 40 are movable, they shall be fitted with slide guides, e.g. shaped as simple fins projecting from the side walls of the inner compartment of the appliance; insulating wall 4, 40 is supported by and can slide over said fins, and may be provided with a gasket or equivalent sealing means on its side edges for thermal insulation purposes.
- Apertures 11 may be fitted with deflectors for conveying the cold air flow into the compartments in a predetermined direction.
- evaporator 6 or fan 8 which in the example provided herein are shown in the upper portion of refrigerating apparatus 1, may likewise be arranged in the lower portion thereof: in this latter case, the cold air pushed by the fan will first follow an upward-directed path within the distribution duct, and then it will flow down again towards the evaporator and back to the fan for a new cycle; of course, in this case it will be possible to stop the cooling of the upper compartment while maintaining the cooling of the lower compartment.
- the refrigerating appliance is an upright no-frost freezer 1", which is therefore suitable for keeping the whole inner space at a temperature substantially lower than 0°C, and an electric resistance 60 is installed in lower compartment 3 for warming said compartment to a temperature between 0°C and 10°C, as shown by way of example in Fig. 8 : with flow regulator 9 in the open condition, lower compartment 3 is cooled by cold air to a temperature between -5°C and -30°C, typically -18°C; should it be desirable to turn the lower compartment 3 into a refrigerator compartment (i.e. operating at a higher temperature between 0°C and 10°C, typically 5°C) or into a higher-temperature freezer compartment (e.g.
- -12°C which temperature is particularly appropriate for preserving foodstuffs to be taken within a short time from freezing or for optimally preserving particular types of foodstuffs, such as ice-cream, for which the traditional 18°C freezing temperature is not recommended), it will be sufficient to turn on the electric resistance, which will then generate heat, thus increasing the compartment temperature to the desired value (i.e. about -12°C or above 0°C, according to the user's preferences).
- This solution allows to obtain a refrigerating apparatus which, while being equipped with a single evaporator of the type adapted to be installed in freezers, has a compartment that can alternatively be kept at ambient temperature or cooled like any traditional freezer compartment (i.e. substantially to -18°C), or else cooled like a higher-temperature freezer compartment (i.e. substantially to -12°C) or like a refrigerator compartment (i.e. substantially operating at temperatures higher than 0°C). It follows that this refrigerating appliance offers wide flexibility of use.
- lower compartment 3 may be converted into a variable-temperature compartment by providing that, within the refrigerating appliance architecture illustrated in Fig. 1 , flow regulator 9 has several degrees of opening, each of which corresponds to a predetermined refrigerating power level supplied to compartment 3.
- flow regulator 9 has several degrees of opening, each of which corresponds to a predetermined refrigerating power level supplied to compartment 3.
