Abstract

An insulated structure comprises a first panel and a second panel coupled to the first panel. The first and second panels define an insulating cavity therebetween. A port is defined by the second panel. The port is an opening into the insulating cavity. A connector is coupled to the second panel. A tube is coupled to the connector and extends parallel along the second panel.

First claim

What is claimed is:

1. An insulated structure for an appliance, comprising:
a first panel;
a second panel coupled to the first panel;
an evacuation port defined by the second panel;
a connector coupled to the second panel and disposed over the port;
a servicing tube coupled to the connector and extending along the second panel, the servicing tube including an attachment end, a maintenance portion, and a stepped portion therebetween; and
a sensor coupled to the connector.

2. The insulated structure of claim 1 , wherein the sensor outwardly extends from the connector and is parallel with the second panel.

3. The insulated structure of claim 2 , wherein the sensor is a pressure sensor configured to monitor the internal pressure of the insulated structure.

4. The insulated structure of claim 1 , wherein the connector, the port, and the servicing tube define a servicing assembly, and wherein the servicing assembly is selectively covered by a cap.

5. The insulated structure of claim 1 , wherein the attachment end is coupled to the connector adjacent to the second panel, and wherein the maintenance portion extends from the stepped portion parallel to the second panel to define a unique space.

6. The insulated structure of claim 1 , wherein the connector is cylindrical and defines an aperture, and wherein the servicing tube is positioned within the aperture, and wherein the connector further defines a base coupled to the second panel and covering the port.

7. A vacuum insulated structure for an appliance, comprising:
a liner;
a wrapper coupled to the liner to form a structural enclosure;
a port defined by the structural enclosure;
a connector defining at least one aperture and coupled to the wrapper covering the port;
a tube coupled to the connector and extending parallel to the structural enclosure, wherein the connector and the tube define a servicing assembly of the vacuum insulated structure; and
a cap coupled to the structural enclosure, wherein the servicing assembly is selectively covered by the cap.

8. The vacuum insulated structure of claim 7 , further including:
a sensor, wherein the sensor is configured to detect a pressure change within the structural enclosure.

9. The vacuum insulated structure of claim 8 , wherein the at least one aperture includes a first aperture and a second aperture, and wherein the sensor is disposed within the first aperture and the tube is positioned within the second aperture.

10. The vacuum insulated structure of claim 7 , wherein the tube includes a repeated-use maintenance portion.

11. The vacuum insulated structure of claim 10 , wherein the repeated-use maintenance portion defines an initial-use length and a reuse length, and wherein the initial-use length is longer than the reuse length.

12. An insulated structure, comprising:
a first panel;
a second panel coupled to the first panel, wherein the first and second panels define an insulating cavity therebetween;
a port defined by the second panel, wherein the port is an opening into the insulating cavity;
a connector coupled to the second panel; and
a tube coupled to the connector and extending parallel along the second panel, wherein, the port, the connector, and the tube define a servicing assembly for the insulated structure, and wherein a cap selectively covers the servicing assembly.

13. The insulated structure of claim 12 , wherein the tube includes an attachment end, a repeated-use maintenance portion, and a stepped portion therebetween, and wherein the stepped portion and the repeated-use maintenance portion define a unique space relative to the second panel.

14. The insulated structure of claim 12 , wherein the tube includes a repeated-use maintenance portion for repeatedly sealing and unsealing the insulated structure.

15. The insulated structure of claim 14 , wherein the repeated-use maintenance portion defines an initial-use length and a reuse length, wherein the initial-use length is longer than the reuse length.

16. The insulated structure of claim 12 , further including:
a sensor outwardly extending from the connector parallel with the second panel.
