For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.

Referring to FIGS. 1-5, a refrigerator 10 is generally shown as a single door refrigerator. The refrigerator 10 includes a cabinet 12 in which stored items such as food and drink are cooled. The cabinet 12 includes a top panel 14, a bottom panel 16, a rear panel 18, and opposing side panels 20 and 22. A door 24 is hinged to the cabinet 12 and includes a top panel 26, a bottom panel 28, a front panel 30, and opposing side panels 32 and 34 partially enclosed by a door frame 36. The door 24 may include a handle, a recessed grip, or other conventional structure to enable a user to access the contents of the cabinet 12. As is known, the cabinet 12 and the door 24 may define a fresh food compartment and a freezer compartment, and stored items may be placed on shelving or inside drawers provided by the cabinet 12 and/or the door 24. In some embodiments, the cabinet 12 and/or the door 24 may be vacuum-insulated.

The door 24 is hinged to the cabinet 12 using one or more hinge assemblies exemplarily shown as first hinge assembly 38A and second hinge assembly 38B. As depicted, hinge assembly 38A is generally provided at a front upper right corner of the refrigerator 10 and hinge assembly 38B is generally provided opposite hinge assembly 38A at a front bottom right corner of the refrigerator 10. In such a configuration, the door 24 opens and closes in a counterclockwise and clockwise direction, respectively. Hinge assemblies 38A, 38B each include a corresponding mounting block 40A, 40B, hinge bracket 42A, 42B, and hinge pin 44A, 44B.

Mounting blocks 40A and 40B are located at a front right corner of the door 24 and are coupled to respective top and bottom panels 26, 28 of the door 24 through a cutout 46 of the door frame 36. It is contemplated that the mounting blocks 40A, 40B may be welded to the door 24 or otherwise secured thereto. Hinge brackets 42A and 42B are coupled to respective top and bottom panels 14, 16 of the cabinet 12 via a corresponding hinge support bracket 48A, 48B using one or more mechanical fasteners 49 or other coupling means. Hinge support brackets 48A and 48B are directly coupled to the respective top and bottom panels 14, 16 of the cabinet 12 using one or more mechanical fasteners 50 or other coupling means. In alternative embodiments, the hinge brackets 42A, 42B may be directly coupled to the cabinet 12. Hinge pins 44A and 44B are each disposed between a corresponding mounting block 40A, 40B and a corresponding hinge bracket 42A, 42B. The resulting couplings enable the entirety of the hinge pins 44A, 44B to be external to the door 24. Additionally, the hinge pins 44A, 44B are free from having to be directly secured to the door 24. Such an arrangement provides several advantages. For example, by locating the hinge pins 44A, 44B external to the door 24, there is no need to alter the door 24 to provide a recess or other accommodation for receiving the hinge pins 44A, 44B. In embodiments where the door 24 is vacuum-insulated, recesses or other accommodations formed in the door 24 may compromise the vacuum seal of the door 24. Accordingly, the hinge assemblies 38A, 38B described herein may aid in preserving the integrity of vacuum-insulated structures.

Optionally, additional mounting blocks 40C and 40D are located at a front left corner of the door 24 and are provided opposite to mounting blocks 40A and 40B, respectively. The mounting blocks 40C and 40D are coupled (e.g., welded) to respective top and bottom panels 26, 28 of the door 24 through a cutout 51 of the door frame 36. In this way, hinge pin 44A and hinge bracket 42A may be engaged to mounting block 40C and hinge pin 44B and hinge bracket 42B may be engaged to mounting block 40D if desiring to change the direction in which the door 24 is opened and closed, for example, from a counterclockwise and clockwise direction to a clockwise and counterclockwise direction, respectively. The hinge brackets 42A, 42B may be engaged to the corresponding hinge support brackets 48A, 48B or directly engaged to the respective top and bottom panels 14, 16 of the cabinet 12 as described herein.

Referring to FIGS. 6 and 7, hinge assembly 38A is shown in greater detail along with an assembly process thereof. It will be understood that hinge assembly 38B is similar to hinge assembly 38A and may be assembled in like fashion. In assembly, mounting block 40A is coupled (e.g., welded) to the top panel 26 of the door 24. In alternative embodiments, mounting block 40A may be engaged to the top panel 26 via mechanical fasteners or other coupling means. Mounting block 40A includes an opening 52 for receiving a lower peg 53 of hinge pin 44A. In the depicted embodiment, hinge pin 44A includes the lower peg 53, an upper peg 54, and a shoulder 56 dividing the lower and upper pegs 53, 54. The upper peg 54 is received in an opening 58 in portion 60 of hinge bracket 42A and a bushing 63 is disposed between the shoulder 56 of hinge pin 44A and portion 60. Portion 60 is vertically offset and cantilevered from portion 62 of hinge bracket 42A. As depicted, portion 60 is raised relative to portion 62, which is engaged to hinge support bracket 48A via one or more weld studs 64 received through corresponding openings 66 in the lower portion 62 and engaged to corresponding hinge nuts 68. It is contemplated that hinge support bracket 48A may be welded to the top panel 14 of the cabinet 12 or engaged thereto using one or more mechanical fasteners 50.

Referring to FIG. 8, hinge bracket 42A of hinge assembly 38A is shown in a planar configuration. Hinge bracket 42A is directly engaged to the top panel 14 of the cabinet 12 via one or mechanical fasteners 70 or other coupling means. Hinge bracket 42A includes a cantilevered portion 72 engaged to the upper peg 54 of hinge pin 44A and extending over the door 24. Hinge pin 44A may be configured according to any of the embodiments described herein and is further engaged to mounting block 40A, which may be welded to the door 24 or otherwise coupled thereto. In the depicted embodiment, hinge pin 44A is external to the door 24 and the door 24 may be vacuum-insulated. The cantilevered portion 72 includes an upward extending flange 74 that spans a width of the cabinet 12 and is coplanar with the front panel 30 of the door 24. The flange 74 is configured as a cosmetic cover and may be used to conceal a gap 76 between the refrigerator 10 and a cabinetry 78 positioned above the refrigerator 10 as exemplarily shown in FIG. 9.
