Referring to FIGS. 1-9, reference numeral 10 generally refers to a vacuum-insulated door for a cooling appliance 12. The vacuum-insulated door 10 includes an outer skin 14 defining a vacuum-insulated cavity 16. A vacuum port 18 is in fluid communication with the vacuum-insulated cavity 16 through the outer skin 14. A vacuum inlet housing 20 is connected to the vacuum port 18 and extends from the outer skin 14. A vacuum port cover assembly 22 includes a bracket 24 connected to the outer skin 14 that includes a first pocket 26 for locating the vacuum inlet housing 20. A cover 28 is connected to the bracket 24.

With reference now to FIGS. 1 and 2, the cooling appliance 12 may be configured as a refrigerator, a freezer, or a combination refrigerator and freezer. The cooling appliance 12 may include one, two, or more vacuum-insulated doors 10. The vacuum-insulated door 10 includes an outer layer 30 that wraps around at least part of the vacuum-insulated door 10. The cooling appliance 12 may include a body 32 that connects to the vacuum-insulated door 10 via a hinge 34. The vacuum-insulated door 10 may include a handle 36 that facilitates moving the vacuum-insulated door 10 between an open position and a closed position. The vacuum-insulated door 10 includes an outer perimeter defined by upper and bottom edges 38 that are spaced vertically by side edges 40. The vacuum-insulated door 10 includes a front surface 42 facing the handle 36 and a rear surface 44 facing the body 32.

With reference now to FIG. 3, the vacuum port 18 may be defined by the rear surface 44. For example, the vacuum port 18 may be located near the bottom edge 38 on the rear surface 44. A sensor 46 may be in fluid communication with the vacuum-insulated cavity 16 through the outer skin 14 for measuring an internal pressure of the vacuum-insulated cavity 16. In some embodiments, the bracket 24 further includes a second pocket 48 for locating the sensor 46. The bracket 24 includes an outer perimeter frame 50 defining an opening and a center support 52 extends across the opening between opposite sides of the outer perimeter frame 50 to divide the opening into the first pocket 26 and the second pocket 48. The vacuum inlet housing 20 and the sensor 46 are horizontally aligned along the bottom edge 38 of the outer skin 14. A vacuum inlet tube 54 may be connected to the vacuum inlet housing 20. The vacuum inlet tube 54 may include a section 56 that extends along the outer skin 14 and the first pocket 26 sized to accommodate the section 56. In this manner, the first pocket 26 may be larger than the second pocket 48. More particularly, the first pocket 26 may extend in a horizontal direction (e.g., in a direction between opposite side edges 40) further than the second pocket 48.

With reference now to FIG. 4, the outer perimeter frame 50 of the bracket 24 includes a pair on longitudinal edges 58 (e.g., a top and lower longitudinal edge) spaced by a pair of lateral edges 60 (e.g., left and right lateral edges). A pair of wings 62 that are located on diametrically opposite sides of the bracket 24 (e.g., on opposite lateral edges 60). The bracket 24 includes a front bracket face 64 configured to face the outer skin 14 and a rear bracket face 66 configured to face the cover 28. The front bracket face 64 of the bracket 24 and the rear surface 44 of the outer skin 14 may include matching contours. For example, both the front bracket face 64 and the rear surface 44 may be substantially planar. The rear bracket face 66 may include an outer lip 68 that extends around the outer perimeter frame 50 and wings 62. The rear bracket face 66 may further include an inner perimeter lip 70 that extends around the first and second pockets 26, 48. The outer lip 68 and inner lip 70 provide rigidity to the bracket 24 and facilitate connection between the bracket 24, the outer skin 14, and the cover 28.

With reference now to FIGS. 5 and 6, the bracket 24 further includes a plurality of slots 72 and the vacuum-insulated door 10 includes a plurality of tabs 74 that are engaged with the slots 72. More particularly, the vacuum-insulated door 10 may include an outer rim 76 that extends at least partially around the outer perimeter (e.g., the whole outer perimeter or the bottom edge 38). The plurality of tabs 74 may align with the lower longitudinal edge 58 of the bracket 24 and the wings 62. The plurality of tabs 74 may include two or more tabs 74, four or more tabs 74, or six or more tabs 74. In the illustrated example, the vacuum-insulated door 10 includes eight tabs 74 along the bottom edge 38 and portion of the side edges 40 proximate the bottom edge 38. The bracket 24 may define an equal number of slots 72 as the number of tabs 74. The tabs 74 may be L-shaped with an interface portion 77 that interlocks with the outer lip 68.

With continued reference to FIGS. 5 and 6, the bracket 24 may further include a plurality of spring fingers 78 that bias the bracket 24 relative to the outer skin 14 and facilitate alignment between the outer skin 14 and the bracket 24. The spring fingers 78 may include groups of two or more spring fingers 78, with each group located on opposite ones of the wings 62. The spring fingers 78 may interlock the outer rim 76 (e.g., a portion of the outer rim 76 associated with the side edges 40). A plurality of studs 80 may extend from the outer skin 14 and the bracket 24 may define a plurality of apertures 82 for receiving the studs 80. In some embodiments, the plurality of studs 80 are welded directly to the outer skin 14. The plurality of studs 80 may each define a threaded body that receives one of a plurality of nuts 84 that lock the bracket 24 to the plurality of studs 80.

With reference now to FIGS. 7-9, the cover 28 may include a plurality of hooks 86 and the bracket 24 may define a plurality of engagement portions 88 that are configured to engage the hooks 86 upon linear movement between the bracket 24 and cover 28 (FIG. 8). More particularly, the cover 28 may include a front cover face 90 that defines the plurality of hooks 86 and a rear cover face 92 that defines a rear, viewable surface to a user. The rear cover face 92 may be substantially planar and lead to a skirt 93 that extends in a direction towards the outer skin 14. In this manner, the cover 28 is connected to the bracket 24 such that the bracket 24 is encased (e.g., non-visible to a user) between the cover 28 and the outer skin 14. Each of the hooks 86 may include an L-shape with a leg portion 94 that overhangs in a direction towards the bracket 24. The engagement portions 88 on the bracket 24 may be defined by recesses along the longitudinal edge 58 that interlock with leg portion 94 by overlapping the leg portion 94 over the engagement portion 88. The leg portions 94 of the plurality of hooks 86 may each face generally the same direction to facilitate linear connection between the bracket 24 and the cover 28. In the illustrated embodiment, a pair of hooks 86 are further aligned with opposite ones of the lateral edges 60 (e.g., the wings 62) and a plurality of hooks 86 are aligned along the top longitudinal edge 58 of the bracket 24. In some embodiments, the wings 62 may each define hook pockets 96 with engagement portions 88 on the perimeter of the hook pockets 96 for connecting to additional hooks 86.

With reference now to FIG. 9, the cover 28 may further include a projection 98 that centers and aligns the cover 28 relative to the bracket 24. The projection 98 may extend between a ramp side 100 and a lock side 102. The ramp side 100 may facilitate connection between the bracket 24 and the cover 28 while the lock side 102 facilitates static connection between the bracket 24 and the cover 28 once connected. The vacuum port cover assembly 22 may further include a central guide 104 that centers and aligns the cover 28 relative to the bracket 24 during connection. More particularly, the central guide 104 may include a first indicia 106 (e.g., a slot or groove) on the bracket 24 and a second indicia 108 (e.g., a slot or groove) on the cover 28 that, when aligned, indicates that the cover 28 and bracket 24 can be connected with linear movement. During assembly, the bracket 24 may be initially connected to the outer skin 14 and, after connection of the bracket, 24, the cover 28 may be connected to the bracket.
