A dishwasher having a treating chamber with one or more sprayers through which liquid is recirculated into the treating chamber, whereby the impact of the spray emitted from the sprayers impacts the structure forming the treating chamber to generate noise. Damping material is applied to structure forming the treating chamber to reduce the sound level of the impact exterior of the dishwasher.

Dishwasher with sound attenuation

An automatic dishwasher can include a tub having a bottom and at least partially defining an open face treating chamber, a base supporting the bottom of the tub and defining a mechanical area beneath the bottom of the tub, at least one sprayer emitting liquid into the treating chamber, and a rotating inlet filter assembly fluidly coupling the treating chamber to the at least one sprayer. A mounting bracket can be provided to secure the rotating inlet filter assembly to the base.

Mounting bracket for a dishwasher

A mounting arrangement secures a refrigerator compressor to a support base member through a plurality of elastomeric mounts secured on pin elements with retainers. The mounts include head portions which extend through openings provided in an elongated plate fixed to the compressor. The mounts are specifically formed with a rounded bottom to pre-load the mounting arrangement and prevent vibration transmission through cores of the mounts. In addition, each mount includes a plurality of vertically spaced rings which provide shock protection against a large impact force by deflecting and potentially contacting each other, while normal vertical isolation occurs by deflection of an uppermost one of the rings. The mounts are formed with various undercuts which allow the mounts to be optimized for the mass and operational frequency of the compressor.

A refrigeration appliance includes an insulated cabinet having a side wall and a machine compartment positioned adjacent the side wall. An aperture is provided through the first side wall to allow air to flow into the machine compartment. An air vent is provided at the exterior surface of the side wall so as to cover the aperture. The air vent having a first set of louvers. A sound barrier is provided at the interior surface of the side wall at the aperture. The sound barrier has a second set of louvers, where the second set of louvers are positioned with respect to the first set of louvers such that there is no mechanical access to components in the machine compartment through the air vent, and such that sounds from within the machine compartment are dampened while still allowing air to flow through the air vent.
