Washing machine appliances and methods of using counterweight amplitude to limit basket speed
A washing machine appliance, including one or more methods of operation, is provided herein. The washing machine appliance includes a wash basket rotatably mounted within a wash tub and being supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining a front displacement amplitude, a rear displacement amplitude, and a wobble angle of the wash tub. Based at least in part on these measured values, front and rear bearing force amplitude thresholds and virtual bearing force values are calculated and compared. If the virtual bearing force value of either the front or rear bearing exceeds the respective bearing force amplitude threshold, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.
Modular laundry system
A modular laundry system includes a washing machine defining a single width and a single width horizontal module below the washing machine. The single width horizontal module below the washing machine includes a cabinet capable of supporting the washing machine thereupon and having an open face. A drawer is slidably mounted to the cabinet for movement between an opened and closed position relative to the open face. A tub is provided within the drawer, and a wash chamber is provided within the tub.
Systems and methods for predicting and preventing a cabinet strike event in a washing machine appliance
Systems and methods for predicting and preventing a cabinet strike event in a washing machine appliance are provided. An exemplary method includes ramping a target speed of a motor from a first speed to a second speed over a ramping period. The method includes computing an average deviation of an observed speed of the motor from the target speed over the ramping period. The method includes computing an average power consumption by the motor over the ramping period. The method includes determining whether both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes rebalancing the load if both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes performing one or more standard operations if both conditions are not satisfied.

If the virtual bearing force value of either the front or rear bearing exceeds the respective bearing force amplitude threshold, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.
Method for detecting a low water level in a washing machine appliance
A washing machine appliance includes a wash tub defining a wash chamber for receipt of a load of articles for washing and a water control valve for regulating a flow of water from a water supply into the wash chamber. A controller is configured for detecting a low water level in the wash chamber, e.g., due to a low water supply pressure, by obtaining a target volume and a fill volume; obtaining an underfill limit based at least in part on the fill volume; obtaining a tub water level after attempting to fill to the target volume; obtaining a new fill level if the tub water level is less than the underfill limit; and filling the wash tub to the new fill level.

Laundry system
A laundry system includes at least one laundry appliance and at least one laundry module below the laundry appliance. The laundry module has a height that is less than the height of the laundry appliance and has a drawer, a tub within the drawer, a wash chamber within the tub for receiving fabric items to be washed, and a control panel for the selection of a wash cycle.
Laundry washing machine and method for controlling a laundry washing machine
Laundry washing machine (1) having an outer casing (2), a washing tub (3), arranged inside the casing (2), a rotatable drum (4), arranged in axially rotating manner inside the washing tub (3) and designed to receive laundry to be washed, and a detergent dispensing assembly (12), designed for supplying laundry detergent into the washing tub (3). The washing machine also has a water softening system (14), designed to receive fresh water from a water mains (13) and reduce the hardness degree of the fresh water in order to supply softened water the detergent dispensing assembly (12) and/or to the washing tub (3), during one or more softened water laundry washing phases, and a control panel (28) configured to allow operator to input information associated with washing performance/s. A controller (15) is configured to control the water softening system (14) in order to perform a washing program comprising one or more softened water laundry washing phases based on input washing performance/s information.
Laundry treatment apparatus
A laundry treatment apparatus includes a tub configured to receive washing water, a drum rotatably disposed in the tub, a water supply unit configured to supply washing water to the tub, and a softener supply unit configured to supply softener to the tub. The water supply unit is in fluidic communication with the softener supply unit.
Washing machine and method of controlling the washing machine
Disclosed herein are a washing machine including a moving mechanism and a method of controlling the washing machine. The washing machine includes a cabinet, a tub disposed inside the cabinet, a drum rotatably provided inside the tub, a front panel which is located at one side of the cabinet and comprises an opening through which laundry is inserted and taken out, and a driving unit which moves the tub to change a space between the tub and the front panel. It is possible to prevent oscillation from being transferred by spacing the front panel and the tub apart during washing. Also, it is possible to provide convenience for a user by arranging the front panel and the tub adjacent to each other while inserting or taking out laundry.
