[0026] Referring to FIG. 2, a first embodiment of the inventive drawer 20 is shown. The drawer 20 includes a body 22 which is made up of a front panel 24, a rear panel 26, two side panels 28, and a floor panel 30. A hub 32 extends upward from a centerpoint of the floor panel 30. In the embodiment illustrated in FIG. 2, the drawer 20 includes four dividers 34 which are pivotably mounted to a bottom portion of the hub 32. In alternative embodiments, the drawer 20 may include fewer or more dividers 34, dividing the drawer 20 into two or more compartments, depending on the number of dividers placed in a use, or upright, position.

[0027] As shown in the embodiment of FIG. 2, one divider extends between hub 32 and the front panel 24. Another divider 34 extends between hub 32 and rear panel 26. A third divider 34 extends between hub 32 and a first side panel 28 and a fourth divider 34 extends between hub 32 and a second side panel 28.

[0028] In FIG. 2, all of the dividers are shown in a use position, thereby dividing body 22 into four substantially equally sized compartments 23. However, in alternative embodiments, the dividers 34 may be positioned as to divide the body 22 into differently sized compartments. In FIG. 3, two of the dividers 34 are in use position and two of the dividers 34 are in non-use position. In a non-use position, a divider 34 lays substantially flat on the floor panel 30. The dividers 34 may pivot upward to a use, or upright, position. The dividers 34 may be held in use position with any means, such as magnetic strips, or clips (not shown). The dividers 34 are sized and configured such that when in the use position, the dividers 34 reach from the floor panel 30 to a lower surface of a ducted cover 36 enclosing the drawer body 22. In FIGS. 2 and 3, the ducted cover 36 is show in partially exploded view. It will be understood that the ducted cover 36 is positioned to serve as a roof of the body 22 and sits atop and may be, in some embodiments, connected to a top edge of the body 22. As shown in the embodiment in FIGS. 2 and 3, when all four dividers 34 are placed in the use position, the body 22 is divided into four compartments 23. Likewise, when three of the dividers 34 are in the use position the drawer body 22 is divided into three compartments 23 and when two of the dividers 34 are in use position, the drawer is divided into two compartments 23 (as is shown in FIG. 3). The dividers 34 in some embodiments may include seals or gaskets along top, bottom and/or side edges in order to prevent air leakage between compartments of the body 22.

[0029] The ducted cover 36 includes a channel 38 providing a fluid connection between an air supply duct (not shown) or an air return duct (not shown). In the embodiment shown in FIG. 3, the ducted cover channel 38 connects to four fans 40 which are located so as to be in fluid connection with each of the four possible compartments of the body 22. As previously mentioned, body 22 may include fewer or more dividers than shown in the Figures. The number of fans and channel divisions may vary depending upon the number of dividers and the maximum number of possible compartments into which the body 22 may be divided. Each of the fans 40 are in electrical communication with a user interface and/or a refrigerator controller. Also located within the body 22 are temperature sensors (no shown), one temperature sensor located within each of the compartments 23 into which the body 22 can be divided. It will be readily understood that when the drawer body 22 is divided into less than the maximum number of compartments, at least one of the compartments will include more than one temperature sensor. Any temperature sensor capable of measuring temperatures within the typical range for refrigerating appliances may be used. Fans 40 place the drawer body 22 in fluid communication with the channel 38.

[0030] FIG. 4 is a perspective view showing the rear side of the drawer 20 shown in FIGS. 2 and 3, in assembled condition. A channel end opening 42 of channel 38 is shown. Opening 42 connects to either an air supply duct or an air return duct. In the embodiment shown in FIG. 4, channel end opening 42 would generally connect to an air supply duct so that cold air may be drawn into the body 22 and any compartments 23 formed therein by the dividers 34. FIG. 4 also illustrates a top surface of the ducted cover 36 being capped with a top cover 58.

[0031] Referring now to FIG. 5, a second embodiment of the inventive drawer 50 is shown in which a ducted floor 51 is illustrated. Ducted floor 50 includes four bottom fans 52 which are in fluid communication with the body 22 and a bottom channel 54 positioned on a lower surface of the ducted floor 51. Ducted floor 51 includes one or more bottom channel end openings 56 which are configured to communicate with and/or connect with an air supply duct and/or an air return duct. The second embodiment further includes dividers 34, hub 32, temperature sensors and drawer body 22 as discussed in connection with FIGS. 2 and 3. As shown in FIG. 5, the second embodiment may include a simple top cover 58 in lieu of a ducted cover 36. In some embodiments, a bottom surface of the ducted floor 51 and the bottom channel 54 may be covered and enclosed with a bottom cover 59.

[0032] FIG. 6 illustrates one embodiment of a hub 32, the hub 32 configured to accommodate up to four dividers 34. In such embodiment, hub 32 includes a center support 60 having a generally square or rectangular cross section. The center support 60 further includes four flanges 62 extending outwardly from each face of center support 60. At least one face of the center support 60 in each possible compartment further includes, in some embodiments, an indentation 64 running along the height of the center support 60. The indentations 64 provide additional means for fluid communication between the body 22 or compartments 23 and either or both of channel 38 of ducted cover 36 and bottom channel 54 of ducted floor 51. Hub 32 further includes means (not shown) for pivotably mounting dividers 34 at a bottom end of hub 32. Such means may include, for example, a depression (not shown) on each face of the center support 60, the depression configured to accept a pin (not shown) protruding from a bottom inner side edge a divider 34. In alternative embodiments, the hub 32 could have any closed cross sectional shape, such as circular, rectangular, or octagonal. In one embodiment, the hub is integrally molded with a floor panel 30 of the body 22. In an alternative embodiment, the hub and dividers may form a removable unit which can be removably placed inside the body 22. In yet another embodiment, the hub 32 may be integrally formed with a top cover 58, a ducted floor 51, and/or a ducted cover 36. In yet another alternative embodiment, the hub 32 is removably attached to a floor panel 30, a top cover 58, a ducted floor 51, and/or a ducted cover 36, such as by bolt, screw, fastener or adhesive.

[0033] FIG. 7 illustrates, in exploded perspective view, a third embodiment of the inventive drawer 70 including both a ducted floor 51 and a ducted cover 36. Drawer 70 further includes a top cover 58, body 22, dividers 34, hub 32, and bottom cover 59. In such embodiment a floor panel 30 is optional. If present, the floor panel 30 includes a grill (not shown) to permit fluid communication between the bottom channel and the body 22 by way of bottom fans 52.

[0034] In view of the first, second and third embodiments illustrated herein, it will be readily understood that any combination of a ducted cover and ducted bottom are within the scope of the invention. Moreover, it should be understood that while the embodiments are illustrated with four dividers 34, the drawer 20, 50, or 70 could alternatively be provided with two, three, or more dividers 34.

[0035] An exemplary but non-limiting user interface 80 is shown in FIG. 8. The user interface 80 may connect directly or indirectly with fans 40 and/or bottom fans 52, the temperature sensors in each compartment, and/or a refrigerating appliance controller. As used herein, refrigerating appliance controller may include any controller used in a refrigerating appliance, such as a main refrigerator controller, a main freezer controller or a subcomponent thereof, such as a drawer controller. As shown in FIG. 8, the user interface 80 may allow a user to select a temperature, temperature range, and/or end use for the drawer 20, 50, or 72 as a whole or for each compartment 23. For example, buttons 81-84 may be used when a drawer is divided into four compartments, allowing the user to select one of four different options for temperature range or intended use for each compartment. Such temperature ranges/end uses may include, for example, meat and seafood, cold drinks, deli goods and snacks, and wine. Alternative options could include, for example, alcoholic beverages, fruits, vegetables, and dairy products. As shown in FIG. 8, rather than selecting an end use, a user may be permitted to select a temperature, including for example, 28° F./−2° C., 32° F./0° C., 37° F./3° C., or 45° F./7° C. In alternative embodiment, an end user may be given an option to choose a temperature range rather than a set temperature. The user interface may be located on a front panel of the drawer or on a refrigerating appliance control center located remotely from the drawer.

[0036] The invention further provides any of the foregoing embodiments, further including a drawer 20, 50, or 72 positioned in a freezer compartment. In such uses, the end uses which may be selected by a user may include, for example, quick freeze, frozen dairy, uncooked meats, frozen vegetable, and frozen prepared foods. Likewise, the user interface for a divisible and temperature controlled drawer in the freezer compartment may be permitted to select a set temperature or temperature range.

[0037] As illustrated in the appended figures, the drawers 20, 50, and 72 are illustrated as having a rectangular shape with a certain relative depth. However, it should be understood that the invention relates to a divisible drawer with temperature control by use of temperature sensors and fans. The inventive drawer may have any configuration and relative depth. For example, inventive drawer may be rectangular and shallow, rectangular and deep, square and shallow or square and deep.

[0038] The temperature within the inventive drawer as a whole or within the compartments thereof may be controlled by forcing air from an air supply duct into the drawer or compartments with passive outflow of air from the drawer or compartments. In an alternative embodiment, air may be sucked out of the drawer or compartments with passive inflow of cold air into the drawer or compartments. In yet another alternative embodiment, the temperature of the drawer or compartments may be regulated by forced air, by use of fans, from an air supply duct into the drawer or compartments in conjunction with forced air venting, by use of fans, from the drawer or compartments into an air return duct and/or into the fresh food compartment.

[0039] In some embodiments, all fans are operated while in other embodiments, each fan is independently operable. The fans may be single speed fans or alternatively, variable speed fans. The fans may be all of a single type or different types of fans.

[0040] While the appended figures illustrate certain components as transparent and other components as opaque, it will be understood that any of the elements may be opaque, translucent, transparent, or any combination thereof.

[0041] The invention has been described with reference to the example embodiments described above. Modifications and alterations will occur to others upon a reading and understanding of this specification. Example embodiments incorporating one or more aspects of the invention are intended to include all such modifications and alterations insofar as they come within the scope of the appended claims and their equivalents.
