  • Patent number: 5284523
    Abstract: A fuzzy logic based control method reduces the amount of water used by a washing machine or dishwasher during a cycle. A sensor detects when the washer has adequate water by monitoring the behavior of the washer pump motor as fresh water is coming in. There is a characteristic oscillation of the magnitude of the motor current as the pump cavitates during this operation, which diminishes when the washer is properly filled. By using fuzzy logic to sense this point of diminished or ceased cavitation and shutting off the incoming water, substantial savings of water can be achieved.

  • Patent number: 5203044
    Abstract: A substantially self-contained system and corresponding method provides practical spot cleaning of soiled garments without requiring the use of chlorinated solvents. A soiled garment may optionally be pretreated with a water base, nonchlorinated cleaner. Thereafter, a relatively high level of vacuum force is applied to the soiled garment to be cleaned while steam is directed onto the spot. The steam comprises the main cleaner when no pretreatment is used, and comprises the flushing agent whenever a water-based pretreatment cleaner is used. Drying effects obtained with the vacuum force may be augmented by the addition of compressed air directed onto the garment. A self-contained workstation practicing such methodology may include an electric water boiler for generating steam and an industrial grade vacuum pick-up with a waste collector for generating the relatively high vacuum force, preferably at least about 80 inches of mercury of static pressure.

  • Patent number: 5199127
    Abstract: The present invention provides a method of rinsing fabric in a washer having a wash chamber rotatable about a vertical axis. Water is added to the wash chamber while rotating the wash chamber about its vertical axis a number of revolutions sufficient to cause the fabric, rinse water and wash chamber to rotate at approximately the same speed. The wash chamber is periodically decelerated to cause the fabric and rinse water to move relative to the wash chamber due to rotational inertia of the fabric and rinse water. The fabric is caused to tumble within the wash chamber as the wash chamber decelerates by impinging the fabric on structures in the wash chamber as the fabric is moving relative to the wash chamber. A spray of rinse water is directed onto the fabric during a first period of time as the fabric is rotating with and tumbling in the wash chamber. The rinse water is then drained from the wash chamber. Finally, the rinse water is removed from the fabric by spinning and draining the wash chamber.

  • Patent number: 5191667
    Abstract: A method of washing fabric in a washer having a wash chamber rotatable about a vertical axis and charged with a detergent solution is provided. The wash chamber is rotated about its vertical axis a number of revolutions sufficient to cause the fabric and detergent solution within the wash chamber to rotate at a speed approximately the same as the wash chamber. The wash chamber is periodically decelerated to cause the fabric and detergent solution to move relative to the wash chamber due to rotational inertia of the fabric and detergent solution. The fabric is caused to tumble within the wash chamber by impinging the fabric on structures in the wash chamber as the fabric is moving relative to the wash chamber. The steps of rotating, decelerating, and tumbling are repeated for a predetermined first period of time. A recirculating spray of concentrated detergent solution is directed on to the fabric during the first period of time as the fabric is rotating with and tumbling in the wash chamber.

  • Patent number: 5191668
    Abstract: The present invention contemplates a rinse process which can be used with any cycle, but which has particular utility following a wash cycle have a highly concentrated detergent solution.The method of rinsing fabric provided by the present invention is useful in a washer having a wash chamber rotatable about a horizontal axis. The steps undertaken in the method begin with loading fabric to be washed into the wash chamber of the washer. The fabric is then washed in a detergent solution while rotating the wash chamber about its horizontal axis for a first period of time. Next the detergent solution is drained from the wash chamber. The fabric is then rinsed by adding water to the wash chamber while spinning the wash chamber at a speed to effect more than a one gravity centrifugal force on the fabric such that the fabric will not tumble within the wash chamber as it spins. Finally, the wash chamber is drained of the rinse water.

  • Patent number: 5191669
    Abstract: An improved wash process is provided for a horizontal washer wherein a concentrated detergent solution is applied to a spinning wash load, the load is spun to effect a greater than one gravity force to maintain the clothes load against the basket wall, and the concentrated detergent solution is recirculated through the clothes load for a first period of time. After the first period of time, the detergent solution is diluted somewhat, although the concentration remains above a normal concentration of 0.06 to 0.28%. The wash chamber will then be spun to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble in the wash chamber. The lesser concentrated detergent solution will then be recirculated on to the fabric during a second time period.
