DETAILED DESCRIPTION OF THE INVENTION

[0027] Referring now to the figures, it is seen that the invention consists of a new sectorized cooling arrangement of selected and controlled temperature for products that require so, particularly beverages, and mainly beverages that require a selected temperature range, such as beer, allowing them to be deposited and removed without having to open other cooling chamber of the refrigerator and thus avoiding the heat input to the same that may harm other products. This, of course, helps to reduce the power consumption of the refrigerator.

[0028] It is so, in accordance with FIGS. 1 to 8, the sectorized cooling arrangement of the present invention can be used in a refrigerator 1 of the type having a main cooling sector 2 with a main access door 3 to the main sector 2 and a freezer or cooling chamber sector 4 with an access door 5 for the same, wherein said access door 5 has a sectorized compartment 6 having a plurality of packaging containers sectors 7 of consumer products, which are defined by a plurality of partitions 8 forming separated housings 9 for said containers 7, as best illustrated in FIG. 5.

[0029] Each of said separated housings 9 for said containers 7 may present a cold air passage regulator towards housings 9. In the preferred embodiment of FIGS. 1 to 8, each regulating device comprises an exhaust fan/air blower 10 which may be a fan. In turn, each air passage regulator or exhaust fan/air blower 10 has a suction side that faces said cooling chamber 4 and one blowing side that faces said sectorized compartment, thereby allowing the entry of cold air inside the housings 9 so as to maintain the desired temperature of the containers disposed thereon. Likewise, said sectorized chamber presents an inner wall 11 which separates said cooling chamber 4 and having a plurality of slots 12 through which cold air flows from the cooling chamber towards the sectorized compartment.

[0030] The arrangement of slots 12 as illustrated in FIG. 6, do not indicate that the invention is limited thereto, but other arrangements such as in the top, side or bottom part of the inner wall 11 can also be considered and used for the slots 12 without any problem. Thus, the cold air passes through the slots 12 and flows into the top of the housings 9 wherein the exhaust fan/air blowers 10 are arranged so that they maintain the temperature of the containers, wherein the air returns to the cooling chamber through the lower end of the housing 9, as best illustrated in FIG. 8. Alternatively, however, and to facilitate the circulation of cold air, each housing 9 may have at least one slot (confirm if well) in one of the walls.

[0031] On the other hand, said sectorized compartment is formed by a compartment structure defined by a plurality of frames 13, 14, 15 and 16 mounted on respective lateral supports with “L” profile 17, a lower support 18 and a top support 19, said compartment being closed towards cooling chamber by said inner wall 11 and being closed outwards by a front panel 20 of said at least one access door 5 refrigerator 1.

[0032] Said front panel 20 of the access door 5 of the refrigerator 1, said compartment structure and said inner wall 11 form a pivot assembly in the refrigerator 1 through at least a first assembly opening hinge 21 for accessing the cooling chamber 4 while said front panel 20 of the access door 5 of the refrigerator is pivotally connected to said compartment structure via at least one second door opening hinge 22 for accessing the sectorized compartment where the containers 7 are arranged.

[0033] In accordance with FIGS. 1 to 5, the first hinge in the upper right corner of the refrigerator 1 is illustrated, while the second hinge 22 is arranged on the left side of the sectorized compartment. This arrangement of the hinges 21 and 22 generates that the access door has to be opened to the right for accessing the cooling chamber 4, or to the left for accessing the sectorized compartment where the containers 7 are. However, this disposition of the hinges is merely illustrative and not limiting to the invention, the arrangement of the hinges may vary in accordance with each manufacturer and specific requirements of each client, to thereby allow the opening of the access door 5 towards both left to right side for accessing the cooling chamber and its corresponding complementary opening movement for accessing the sectorized compartment. That is, the access door 5 of the present invention may have the following opening configurations: [0034] Opening to the right for accessing to the cooling chamber and opening to the left for accessing the sectorized compartment; or else, [0035] Opening to the left for accessing the cooling chamber and opening to the right for accessing the sectorized compartment.

[0036] Although the opening of the access door has been exemplified to the left or right for accessing the cooling chamber, with subsequent opening to the left or right for accessing the sectorized compartment, this does not imply that the invention is limited to such configurations, but the invention also contemplates the opening of the access door up and down for accessing the cooling chamber with its correlative opening up or down for accessing the sectorized compartment.

[0037] It is emphasized that, said at least one access door 5 with a sectorized compartment is the freezer door. Likewise, said sectorized compartment can have at least one temperature sensor (not shown) while said front panel 20 may have at least one visual access window 23 for such consumer products housed in the housings 9 of the sectorized compartment said window 23 being together with a transparent sheet 24 which may be glass or any plastic material well known in the art field.

[0038] In turn, the front panel 20 is mounted in said compartment structure through a top cap 25, a bottom cap 26 and said second hinges 22 which are fixed to said top cap 25 and bottom cap 26. In turn, front panel 20 has at least one gripping/opening arrangement 27 to facilitate the opening/closing thereof and at least one temperature display screen 28 within said sectorized compartment. It is emphasized that, said main access door 3 also has a gripping/opening arrangement 29 to facilitate the opening/closing thereof.

[0039] According now to FIGS. 9 to 14, an alternative of the invention is illustrated, in which compartment 6 with housings 9 is provided with airflow-regulating devices, also known as cold air passage regulators from the cooling chamber to the interior of the sectorized compartment, also all in accordance with the invention.

[0040] It is noteworthy that in FIGS. 9 to 14 the same reference numbers of FIGS. 1 to 8 will be used to describe those equal parts, while reference numbers from 101 will be used to describe the pertinent parts to the regulating device.

[0041] In accordance with this embodiment of the present invention, the airflow-regulating device is indicated by the general reference 101 and it comprises at least one rotating cap 102 having a window 103, at least a gripping element 104, a pair of indicators comprising a form of “+” 105 and “−” 106 arranged on either side of gripping element 104 and an internal thread 107. While it has been indicated that indicators have a shape of “+” and “−”, this does not mean that the invention is limited thereto, but other forms and arrangements can be considered and used without any problem in the present invention to indicate a greater or lesser opening of the air regulation passage.

[0042] Also, the device of the invention has at least a main body 108 having an upper end 109 with a face 110 provided with a window 111, and an open lower end 112. The main body 108 is threaded to rotating cap 102 by an external thread 113 formed in a portion of upper end 109. Furthermore, the present invention is provided with at least one base 114 comprising a base platform 115, a projection 116 which is coupled to the inside of lower end 112 main body 108 and a central through hole 117, wherein said base platform 115 presents a section greater than the projection section 116.

[0043] In accordance with FIGS. 9 and 10, we can observe that the device of the invention is mounted between respective holes 118 made in one of the walls of the housing 9 and the inner wall 11. Thus, the base platform 115 is facing the cooling chamber 4 while the rotating cap 102 is facing the interior of the housing 9 of the sectorized compartment.

[0044] Thus, the flow rate or airflow no longer enters forcibly by fan 10 through the top of the housing 9, as illustrated in FIG. 1, but the air flow entering through the device of the invention, FIG. 9, i.e., the air flow enters through the central through hole 117 of the base 114, flows through the inside the main body 108, passes through the windows 111 and 103 of the face 110 and the rotating cap 102 respectively, and enters the housing 9 to carry out the cooling of the container.

[0045] While the illustrated device of the present invention comprises a cylindrical structure, this does not imply that the invention is limited thereto, but other forms can also be considered and used.

[0046] Regarding the air flow regulation, the same is illustrated schematically in FIGS. 12 to 14. The air flow regulation depends on the position of the window 103 of the rotating cap 102 with respect to the face 110—window 111 of the main body 108. In FIG. 12, an intermediate position for the air intake can be seen, in which the window 103 of the cap 102 comprises one half of the face 110 and one half of the window 111 of the main body 108.

[0047] If one desires to reduce or restrict the air flow, cap 102 must be rotated by gripping the gripping element 104, counterclockwise in accordance with FIG. 13. In this case, window 103 covers a greater portion of face 110 of window 111. Otherwise, if one desires to increase or enhance the air flow, cap 102 must be rotated clockwise as illustrated in FIG. 14. In this case, window 103 covers a larger portion of window 111 than of face 110.

[0048] In this way, we can carry out the regulation of the air flow entering the housing, in a practical, quick and easy way.

[0049] It is noteworthy that, although it has been described that counterclockwise rotation of the top allows a reduction of air flow, and that the clockwise rotation of the cap allows an increase of air flow, this does not imply that the invention is limited thereto, but the invention can be modified and adapted to reverse the directions of rotation without any inconvenience.

[0050] Thus, the sectorized cooling arrangement for refrigerators of the present invention is incorporated and built, where the same allows creating a space of selected and controlled temperature for products that require so, with direct access to these products without having to open other cooling chambers of the refrigerator. Also, the invention does not reduce the available space for product storage nor varies the consuming cooling category, using the same standard cooling source of any refrigerator.
