Abstract: A laundry appliance includes a rotating drum for processing laundry. A heat pump system has a heat exchanger that is positioned within an air conditioning chamber. A blower directs process air through an air path that includes the rotating drum and the air conditioning chamber. An insulating member positioned between a top portion of the heat exchanger and an underside of a cover member for the air conditioning chamber. The insulating member directs the process air through the heat exchanger and away from the underside of the cover member and absorbs sound and vibration generated by movement of process air through the heat exchanger.

Abstract: A drive motor for a laundry appliance includes a stator having a plurality of windings that extend around teeth of the stator. A rotor is in electromagnetic communication with the stator. The rotor is coupled to a drive shaft that extends through the stator. When the winding of the stator is electrically energized, the rotor rotates relative to the stator at a predetermined range of rotational frequencies that includes a baseline natural frequency of the rotor. A harmonic-modulating member is attached to the rotor that modulates the baseline natural frequency of the rotor to be a modulated natural frequency. The predetermined range of rotational frequencies is free of the modulated natural frequency of the rotor.

Abstract: A laundry appliance includes a cabinet having a rotating drum operably positioned therein for processing fabric. At least one transducer is positioned proximate the drum that provides an ultrasonic resonance that is directed into an interior chamber of the drum. The ultrasonic resonance is adapted to be directed into damp fabric being treated within the interior chamber. The ultrasonic resonance serves to modify water trapped within the damp fabric into a substantially gaseous form.

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.
