摘要： A control for an automatic washing machine with a reversing permanent split capacitor (PSC) drive motor. Separate ferrite core sensors surround each of two PSC motor windings. A sense winding is threaded through both sensors. A brief output voltage is generated whenever the alternating current in either PSC motor winding passes through a zero-crossing and when the sense winding is wound with proper mutual polarity, an output voltage is generated in response to zero-crossings of a brief, residual alternating current which flows in both PSC motor windings and the capacitor when the rotating PSC motor is cycled OFF. The circuitry, in combination with the sensors, samples the leading or lagging phase angle of the PSC motor auxiliary or main winding, respectively, at a sample rate of two-times the line frequency when the PSC motor is ON; and further monitors the PSC motor braking phenomena by counting the residual current alternations when the PSC motor is cycled OFF following the powered portion of each CW or CCW agitator stroke. The raw PSC motor phase data is used in microcomputer programs to compute motor start time or load torque dither. This computed information and the PSC motor braking data, is used by other software programs to automatically control various functions of the washing machine such as the fill water level and agitator stroke angle; to control events in an operational sequence such as the duration of the agitation and spin operations; and to provide diagnostic information such as spin off-balance detection.

摘要： An improved wash process is provided wherein during a low speed spin portion of the wash process, the wash chamber or wash basket is rotated about its horizontal axis at a spin speed to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble in the wash chamber. During this tumbling action a recirculating spray of highly concentrated detergent solution, preferably in the range of at least 0.5% to 12% by weight is directed onto the fabric 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 .28%. The wash chamber will again 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.

摘要： A clutch mechanism is provided for the drive system of an automatic washer having a vertical axis agitator, a concentrically mounted wash basket, and a motor drivingly connected to the agitator to selectively oscillate or rotate the agitator about a vertical axis. The clutch mechanism selectively drivingly connects the wash basket with the motor for simultaneous rotation of the wash basket with the agitator during a water extraction mode of the washer. The clutch mechanism includes a first clutch member drivingly connected to the motor, and a second clutch member drivingly connected to the wash basket and selectively axially actuable for driving engagement with the first clutch member. A stationary cam housing is located adajcent the second clutch member, and a rotatable ring is disposed between the cam housing and the second clutch member. Cam elements are provided between the ring and the cam housing for selectively actuating the second clutch member into driving engagement with the first clutch member upon rotation of the ring within the cam housing. Opposing engagement surfaces of the clutch members are provided with alternating radially extending splines and grooves having a generally sawtooth profile. The splines of one of the clutch members are provided with squared tips, and the grooves of the other clutch member are provided with squared recesses, so that the shape of the corresponding splines and recesses provide an easily achieved yet secure connection when the clutch members are drivingly engaged.

摘要： An automatic washer is provided for performing a concentrated wash process in which there is a rotatable wash basket in a motive apparatus for rotating the wash basket about a generally vertical axis as well as being operable to oscillate the wash basket to impart an agitation force to the wash load carried in the basket. Vertical fins and spray inlets are provided adjacent the peripheral wall of the basket to impart an agitation force to the wash load. Also, a central post is mounted within the basket for rotation with the basket and a spray device is mounted on the post for directing a detergent solution against the wash load.
