Whirlpool Corporation - Benton Harbor MI

International Classification:

B08B 3/00

US Classification:

134200, 134114, 134201

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.

Assignee:

Maytag Corporation - Benton Harbor MI

International Classification:

B08B 3/02

US Classification:

134 252, 134111

Abstract:

A dishwasher includes a pump assembly having a chopper blade and apertured plate arrangement which function to chop soil particles entrained in a flow of washing fluid. The chopper blade floats or axially slides relative to a drive member from a first position spaced from the apertured plate to a second position closer to the apertured plate in order to macerate the soil particles. The chopper blade is actually mounted to a hub member including a shaft portion that extends into and abuts an inner portion of an impeller to maintain a desired spacing between the chopper blade and the apertured plate, while transferring drive from the drive member to both the chopper blade and impeller.

Assignee:

Maytag Corporation - Newton IA

International Classification:

B08B 300

US Classification:

134 56D

Abstract:

The dishwasher of the present invention is adapted to skip a drain cycle if the water in the dishwasher is clean enough. The invention uses a turbidity sensor to sense the turbidity of the water. If the sensed turbidity is below a threshold value, the drain motor and the water valve are disabled to prevent the water from being drained and to prevent additional water from being introduced into the dishwasher.
