Abstract
A dishwasher includes a frontal frame, a tub having a plurality of walls collectively define a washing chamber, and a door pivotally mounted to the frontal frame for sealing the washing chamber. During a washing operation, sound generated by operation of a mechanical pump escapes from below the dishwasher. To minimize sound from escaping and to provide a more enjoyable environment, a sound sealing system is mounted at a bottom portion of the dishwasher door. The sound seal system includes a sound tray that extends across the frontal frame below a bottom edge portion of the door. The sound tray can be directly, pivotally attached to the door, or an additional flexible seal is employed to span and seal a gap between the sound tray and the bottom portion of the door.
