Dishwasher having sound attenuating structures
First Claim
1. A dishwasher configured to clean dishware comprising:
- a tub configured to receive and hold the dishware; and
a first panel of an acoustic composite membrane including a layer of an acoustic tape, the acoustic tape comprising a plurality of first fibers extending in a first direction and a plurality of second fibers extending in a second direction, the acoustic tape being positioned and configured to convert at least a portion of a sound power level generated by the dishwasher into heat such that the sound power level outside the dishwasher is reduced, wherein the first and second directions perpendicular to each other forming a grid-like pattern,wherein the acoustic composite membrane further includes a first foam layer configured to absorb at least a portion of the sound power level and to reduce the speed of the sound power level prior to the sound power level reaching the acoustic tape, andwherein the acoustic composite membrane further includes a second foam layer and a vinyl layer between the first and second foam layers, the vinyl layer being configured to convert at least a portion of the sound power level into heat.

Abstract
Embodiments of dishwashers with sound attenuating properties are provided. The dishwashers include one or more laminated structures for attenuating sound. The structure may include a layer of an acoustic tape having a plurality of bi-direction fibers configured to redirect and convert sound generated by the dishwasher into heat such that the sound perceivable outside the dishwasher is reduced. The structure may further include one or more layers of foam for absorbing sound and one or more layers of vinyl for converting sound into heat. Panels of the laminated structure may be positioned in, around, and along the toe plate assembly, the door assembly, the base and tub of the dishwasher, and framing elements of the dishwasher.

9. A dishwasher configured to clean dishware comprising:
-
a tub configured to receive and hold the dishware; and a laminated structure positioned and configured to attenuate a sound power level generated by the dishwasher, the laminated structure including a layer of an acoustic tape, the acoustic tape comprising a non-fibrous layer and a plurality of fibers mounted thereon, and wherein the plurality of fibers is configured to convert at least a portion of a sound power level generated by the dishwasher into heat such that the sound power level outside the dishwasher is reduced, wherein the laminated structure further includes first and second foam layers configured to absorb at least a portion of the sound power level and to reduce the speed of the sound power level prior to the sound power level reaching the acoustic tape and a vinyl layer between the first and second foam layers, the vinyl layer being configured to convert at least a portion of the sound power level into heat. - View Dependent Claims (10, 11, 12)

13. A method of attenuating sound generated from a dishwasher, the method comprising:
-
providing a dishwasher, including a tub configured to receive and hold dishware, a door assembly configured to provide access to an interior of the tub, a frame including a base configured to support the tub and one or more framing elements extending from the base around the tub; placing an acoustic composite membrane in a position external to the tub, the acoustic composite membrane configured to convert at least a portion of the sound generated by the dishwasher into heat, the acoustic composite membrane comprising a layer of an acoustic tape, the acoustic tape including a plurality of first fibers extending in a first direction and a plurality of second fibers extending in a second direction, wherein the acoustic composite membrane further comprises a first foam layer configured to absorb at least a portion of the sound and to reduce the speed of the sound prior to the sound reaching the acoustic tape, and wherein the acoustic composite membrane further comprises a second foam layer and a vinyl layer between the first and second foam layers, the vinyl layer being configured to convert at least a portion of the sound power level into heat. - View Dependent Claims (14, 15, 16, 17)
