Abstract

A laundry appliance includes a motor that operates a rotating drum for processing laundry. A rear wall of a cabinet is located behind the rotating drum. An interior wall is offset from the rear wall and defines a cavity. First and second insulating members are positioned in an offset configuration within the cavity.

Claims

1. A laundry appliance comprising:

a motor that operates a rotating drum for processing laundry;

a rear wall of a cabinet that is located behind the rotating drum;

an interior wall that is offset from the rear wall and that defines a cavity therebetween; and

first and second insulating members that are positioned apart from one another in an offset configuration within the cavity, wherein an interior support extends through the cavity and between the rear wall and the interior wall, and wherein the interior support extends through each of the first and second insulating members and maintains the first and second insulating members in a parallel configuration within the cavity, wherein the first insulating member is attached to the rear wall and the second insulting member is attached to the interior wall.

2. The laundry appliance of claim 1, wherein the first and second insulating members are oriented in a parallel configuration within the cavity.

3. The laundry appliance of claim 1, wherein a gap is defined between the first and second insulating members, and wherein the gap and the first and second insulating members cooperate to absorb vibrations generated by the rotating drum during operation of the motor.

4. The laundry appliance of claim 3, wherein the gap has a thickness of approximately 15 millimeters.

5. The laundry appliance of claim 1, wherein the interior wall is coupled to a base pan, wherein the base pan at least partially supports the rear wall from below.

6. The laundry appliance of claim 5, wherein the base pan and the interior wall are integrally formed as a single structural member.

7. The laundry appliance of claim 1, further comprising:

an upper insulating member that is positioned on the rear wall near the motor for the rotating drum.

8. The laundry appliance of claim 1, wherein the first and second insulating members are damping asphalt sheets.

9. A laundry appliance comprising:

a base pan and a rear wall that are connected to partially form an appliance cabinet;

a motor that rotates a drum within the appliance cabinet;

a first insulating member that is attached to the rear wall; and

a second insulating member that is attached to a vertical portion of the base pan;

wherein

the first and second insulating members define a gap therebetween;

the gap and the first and second insulating members cooperate to absorb vibrations generated by the drum during operation of the motor;

an interior support extends through the gap and between the rear wall and the vertical portion of the base pan; and

the interior support extends through each of the first and second insulating members and maintains the first and second insulating members in a parallel configuration.

10. The laundry appliance of claim 9, wherein the gap has a thickness of approximately 15 millimeters.

11. The laundry appliance of claim 9, further comprising:

an upper insulating member that is positioned on the rear wall near the drum, wherein the upper insulating member includes a recess that at least partially encircles the motor for the rotating drum.

12. A laundry appliance comprising:

a base pan and a rear wall that are connected to partially form a cavity within an appliance cabinet;

a motor that operates a rotating drum within the appliance cabinet;

first and second insulating members that are positioned within the cavity and define a gap therebetween, the first and second insulating members attached to the rear wall and a vertical portion of the base pan, respectively;

an interior support that extends through the cavity and between the rear wall and the vertical portion of the base pan, and wherein the interior support extends through each of the first and second insulating members and maintains the first and second insulating members in a parallel configuration; and

an upper insulating member that is positioned on the rear wall near the rotating drum, wherein the upper insulating member and the first and second insulating members cooperate to absorb vibrations generated by the rotating drum during operation of the motor.

13. The laundry appliance of claim 12, wherein the upper insulating member includes a recess that at least partially encircles the motor for the rotating drum.

14. The laundry appliance of claim 12, wherein the first and second insulating members at least partially engage a blower that directs process air through the rotating drum.
