摘要： A method and apparatus for sensing the level of fluid present in a dispenser, such as a detergent or fabric softener dispenser, of a washing machine appliance and to detecting an out of balance condition for such appliance is provided. A pressure sensor is used to determine the level of fluid present and to provide indications of the same at various levels of use of the fluid. One or more pressure sensors can also be used to detect an out of balance condition when the appliance is a washing machine.

摘要： A washing machine appliance, such as a consumer washing machine, includes a casing, and a tub disposed within the casing. A wash basket is received within the tub and is configured for receipt of articles to be washed. A diffuser plate defines a continuous bottom of the wash basket and includes a plurality of passages defined therethrough. An impeller system is operably configured within the tub below the diffuser plate and includes at least one impeller that is rotationally driven during a wash cycle to direct high velocity wash water through the passages with sufficient energy to move and wash articles within the wash basket.

摘要： Systems and methods for detecting an out of balance condition for a washing machine are disclosed. The wash basket of the washing machine is rotated at a constant predetermined rotational speed. If the washing machine has an unbalanced load, the wash tub will strike the cabinet as the basket rotates in the wash tub. The tub strikes cause the wash basket to lose momentum. The inverter drive control system causes the inverter to provide more current through the motor phases to the motor to maintain constant speed. From the value of the current, the severity of the tub strikes during a test period can be determined. An out of balance condition can be detected and measured based at least in part on the severity of the tub strikes.

摘要： A method of braking a washing machine from an operational speed to a reduced non-zero speed is provided (as well as a washing machine incorporating the method) for a washing machine driven by one of a synchronous or asynchronous motor. Upon receipt of a speed reduction signal, the motor rotating magnetic fields are collapsed for a defined time period. After the defined time period, DC braking voltage is applied to the motor stator windings at a controlled ramp-up rate to an amplitude to generate a controlled ramped braking torque on the motor until the motor has slowed to a defined reduced speed. Thereafter, the amplitude of the DC braking voltage is set to 0V and the motor is soft started to an amplitude and reduced frequency needed to maintain the defined reduced speed.

摘要： A method of braking a washing machine from an operational speed to a zero speed is provided (as well as a washing machine incorporating the method) for a washing machine driven by one of a synchronous or asynchronous motor. Upon receipt of a stop signal, collapsing the motor rotating magnetic fields are collapsed for a predefined time period. After the predefined time period, DC braking voltage is applied to the motor stator windings at a controlled ramp-up rate to a fixed amplitude to generate a controlled ramped braking torque on the motor. The braking torque is applied until the motor is stopped.

摘要： The present subject matter relates to methods and apparatus for controlling operation of a washing machine motor. Different control algorithms may be used during different time periods of operation of the motor where each algorithm is configured to provide different operating characteristics of the motor based on the needs of the washing machine system. The method and apparatus both provide for changing from one motor control algorithm to another algorithm while the motor is spinning. For certain type motors, a time period may be established between operation of the motor under a first or second control algorithms where no energy is supplied to the motor but the motor is permitted to continue to spin. During this period of time for these type motors, magnetic fields in the motor are permitted to subside prior to application of the second control algorithm.

摘要： The present subject matter relates to methods and apparatus for measuring energy usage in an appliance, particularly a washing appliance. A display, that may be a home energy monitor, is associated with the appliance. The appliance may include an AC-DC power supply and a controllable inverter configured to supply power to a motor associated with the appliance. Real power consumption is calculated by a controller that may also be used to control the inverter and other operational aspects of the appliance and causes the calculated real power to be displayed on the display.
