Filling ports for insulated structures incorporated within an appliance
An appliance includes an outer wrapper and an inner liner that form a structural cabinet having an insulating cavity defined between the inner liner and the outer wrapper. An elliptical insulation port is defined within the outer wrapper, wherein the elliptical insulation port is configured to allow passage of a cylindrical insulation conduit when the insulation conduit is positioned at an oblique angle relative to the structural cabinet. An insulation material is disposed within the insulating cavity. A sealing cap covers the elliptical insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity.
1 . An insulated structure for an appliance comprising:
an outer structure that defines an insulating cavity within the outer structure;
an insulation port defined within the outer structure, wherein the insulation port is defined by a perimetrical flange that extends perpendicularly from an aperture defined within the outer structure;
an insulation material that is disposed within the insulating cavity; and
a sealing cap that covers the insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity, wherein the insulation port and the sealing cap cooperate to define a bracket receptacle, wherein an inner surface of the perimetrical flange receives the sealing cap, wherein the sealing cap includes a vacuum port that extends through the sealing cap.
2 . The insulated structure of claim 1 , further comprising:
a hinge bracket that is attached to the bracket receptacle, wherein the hinge bracket conceals the sealing cap and the insulation port from view.
3 . The insulated structure of claim 1 , wherein the insulation port includes a reinforcing member that reinforces the outer structure at the sealing cap.
4 . The insulated structure of claim 3 , wherein the reinforcing member is disposed on an interior surface of the outer structure.
5 . The insulated structure of claim 1 , wherein the perimetrical flange extends from the aperture and away from the insulating cavity.
6 . The insulated structure of claim 1 , wherein the vacuum port is sealed to define an at least partial vacuum within the insulating cavity.
7 . The insulated structure of claim 6 , wherein the vacuum port of the sealing cap is crimped to define a substantially air-tight seal.
8 . The insulated structure of claim 6 , wherein the vacuum port is sealed with a plug that is disposed within the vacuum port.
9 . The insulated structure of claim 6 , wherein a reinforcing member surrounds the sealing cap, wherein the reinforcing member supports the bracket receptacle of the sealing cap.
10 . The insulated structure of claim 9 , wherein a filter is disposed on the sealing cap proximate the vacuum port, the filter configured to prevent the insulation material from infiltrating the bracket receptacle.
11 . The insulated structure of claim 1 , where the vacuum port is integrally formed with the sealing cap and is disposed within the bracket receptacle.
12 . An insulated structure comprising:
an outer structure having an interior surface that defines an insulating cavity therein, wherein an insulation port is defined within the outer structure; and
a sealing cap that covers the insulation port, wherein the sealing cap includes a protrusion that extends at least partially through the insulation port to define a bracket receptacle, wherein the sealing cap includes a vacuum port that extends through the sealing cap within the bracket receptacle.
13 . The insulated structure of claim 12 , further comprising:
a hinge bracket that is disposed within the bracket receptacle and is attached to the outer structure, wherein the hinge bracket conceals the sealing cap and the vacuum port.
14 . The insulated structure of claim 12 , wherein the vacuum port is integrally formed with the sealing cap.
15 . The insulated structure of claim 13 , further comprising an insulating material that is disposed within the insulating cavity.
16 . The insulated structure of claim 13 , wherein the outer structure defines a structural cabinet, and wherein the hinge bracket includes a portion of a hinge that extends to a rotationally operable door panel.
17 . The insulated structure of claim 12 , wherein the insulation port is defined by a perimetrical flange that extends perpendicularly from an aperture defined within the outer structure, wherein an inner surface of the perimetrical flange receives the sealing cap.
18 . The insulated structure of claim 17 , wherein the perimetrical flange extends away from the insulating cavity.
19 . An insulated structure for an appliance comprising:
an outer structure having an interior surface that defines an insulating cavity therein;
an insulation port defined within the outer structure;
a sealing cap that covers the insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity, wherein the insulation port and the sealing cap cooperate to define a bracket receptacle;
a vacuum port that extends through the sealing cap, wherein the vacuum port is sealed to define an at least partial vacuum within the insulating cavity; and
a hinge bracket that is disposed within the bracket receptacle and conceals the sealing cap and the insulation port from view.
20 . The insulated structure of claim 19 , further comprising an insulating material that is disposed within the insulating cavity, wherein the protrusion is configured to engage the insulating material within the insulating cavity.
