摘要： The present invention contemplates a rinse process which can be used with any wash 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.

摘要： 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 .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.

摘要： A control for a clothes dryer with an induction drive motor and an electric resistance heater element. A single sense winding is threaded through sensors monitoring drive motor current and heater current, generating an output voltage each time the alternating motor or heater current passes through a zero-crossing. The control monitors the ON/OFF condition of the heater and samples the lagging phase angle of the motor current, to provide an improved means of detecting when the clothes load is dry by measuring variation in motor torque due to minute differences in the way that the clothes load is tumbling from one drum revolution to the next revolution, ignoring cyclical, repetitive variation due to uneven drum rotational friction. The control provides a clothes cooldown period with controlled moisture regain as per the user dryness selection. In addition, numerous diagnostic conditions are monitored at the start of each cycle, or, throughout each cycle, including: 208 or 240 VAC service voltage identification; motor start detection; drum acceleration detection; empty drum detection; motor or heater open/short circuit detection; open door detection; broken belt detection; and restricted air flow detection.

摘要： A motor controller for a single phase induction motor (SPIM), wherein the SPIM is driven by a square wave above or below rated frequencies. The square wave may be shaped by introducing one or more notches to eliminate or suppress undesirable harmonics, to reduce the amplitude of the fundamental, to provide desirable voltage control, or to provide desirable voltage to frequency control. The control topology may include switches, main winding taps and switchable capacitors to accommodate selection between line and square wave driving, temporary capacitance increases, or other advantages.

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. 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： PA-5740-O-AW-USA A method for rinsing a textile wash load is provided for use in a vertical axis washing machine in which a plurality of initial spray rinses are used in which the released water is discharged directly to drain and a plurality of subsequent spray rinses are used in which the water is recirculated through the spinning clothes load for a predetermined length of time before being discharged to drain. Enhanced detergent and soil removal with less water usage is achieved with this method. 29

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： A relay control for a cooking appliance having a heating element includes a sensor for detectirg the occurrence of an arc upon a change of state of a relay coupled between the heating element and a power supply. Upon detecting an arc, the sensor provides a timing signal which is coupled to a microprocessor that controls the energization and deenergization of the relay. The microprocessor is responsive to the timing signal from the sensor to determine the time delay between the last energization/deenergization of the relay and the changing of the relay's state. From the time delay, the microprocessor determines a delay constant. Subsequently, the microprocessor energizes the relay at a time after the detection of a zero crossover point of the power supply signal, wherein the time is equal to the determined delay constant to cause the relay to change state at or slightly before a zero crossover point of the power supply signal. The sensor may take the form of an optical sensor, such as a phototransistor, mounted inside the housing of the relay or outside of, but within optical range of, the housing, in which case the housing would be transparent to the optical wavelength of an arc. Alternatively, the sensor may include an electromagnetic or RF pick-up coil for sensing an electromagnetic or RF signal in the radio frequency (RF) range radiated upon the generation of an arc. Such an RF pick-up coil may be mounted inside the housing of the relay or outside of the housing but within the range of the housing, in which case the housing would be formed of materials that would not interfere with the RF signal from an arc. Alternatively, the sensor may be a vibration sensor, such as a piezoelectric transducer, capable of detecting vibrations associated with the opening or closing of the relay contacts.
