## Abstract

An insulated structure for an appliance includes a plurality of walls, a cavity defined by the plurality of walls, and an aperture defined by one of the plurality of walls. The aperture is employed in evacuating the cavity to establish a less-than-atmospheric pressure within the cavity. A base structure is coupled to an interior surface of the one of the plurality of walls that defines the aperture. The base structure is aligned with the aperture. A pressure sensor is received by the base structure. The base structure and the pressure sensor together define a pressure-sensing assembly.

## Claims

### Claim 1

An insulated structure for an appliance, comprising:
a plurality of walls;
a cavity defined by the plurality of walls;
an aperture defined by one of the plurality of walls;
a base structure coupled to an interior surface of the one of the plurality of walls that defines the aperture, wherein the base structure is aligned with the aperture;
a pressure sensor received by the base structure, wherein the base structure and the pressure sensor together define a pressure-sensing assembly; and
a cover that is removably coupled to the aperture, wherein a position of the pressure-sensing assembly remains constant independent of whether the cover is in a coupled state or a decoupled state relative to the aperture.

### Claim 2 (depends on 1)

The insulated structure for an appliance of claim 1, wherein the pressure-sensing assembly fits below the cover when the cover is in the coupled state.

### Claim 3 (depends on 1)

The insulated structure for an appliance of claim 1, wherein the aperture is employed in evacuating the cavity to establish a less-than-atmospheric pressure within the cavity.

### Claim 4 (depends on 1)

The insulated structure for an appliance of claim 1, wherein the base structure defines one or more channels.

### Claim 5 (depends on 4)

The insulated structure for an appliance of claim 10, wherein the second channel receives the pressure sensor.

### Claim 12 (depends on 11)

The insulated structure for an appliance of claim 11, wherein the first channel and the second channel are oriented perpendicular to one another.

### Claim 13 (depends on 10)

The insulated structure for an appliance of claim 10, wherein the first channel and the second channel are in fluid communication with one another.

### Claim 14

An insulated structure for an appliance, comprising:
a plurality of walls;
a cavity defined by the plurality of walls;
an aperture defined by one of the plurality of walls, wherein the aperture is employed in evacuating the cavity to establish a less-than-atmospheric pressure within the cavity;
a base structure coupled to an interior surface of the one of the plurality of walls that defines the aperture, wherein the base structure is aligned with the aperture, wherein the base structure defines one or more channels, wherein at least one of the one or more channels is positioned over the aperture;
a pressure sensor that is received by the base structure, wherein the base structure and the pressure sensor together define a pressure-sensing assembly, and wherein the pressure sensor is a microelectromechanical system; and
a cover that is removably coupled to the aperture, wherein a position of the pressure-sensing assembly remains constant independent of whether the cover is in a coupled state or a decoupled state relative to the aperture, wherein the pressure-sensing assembly fits below the cover when the cover is in the coupled state.

### Claim 15 (depends on 14)

The insulated structure for an appliance of claim 14, wherein at least one of the one or more channels receives the pressure sensor, and wherein the one or more channels comprises a plurality of diameters.

### Claim 16 (depends on 14)

The insulated structure for an appliance of claim 14, further comprising:
a first polymeric plate; and
a second polymeric plate adhered to the first polymeric plate, wherein electrical leads of the pressure sensor extend through the first polymeric plate and the second polymeric plate.

### Claim 17 (depends on 16)

The insulated structure for an appliance of claim 16, wherein the one or more channels comprises a first channel and a second channel, and wherein the first channel is positioned over the aperture.

### Claim 18 (depends on 17)
