A washing machine includes a power source, a drum, and a transmission. The transmission is configured to deliver power from the power source to the drum. The transmission includes a housing, a shaft, and a bushing. The housing defines a cavity. The shaft is disposed within the cavity and is configured to receive power from the power source. The bushing is disposed about the shaft. The bushing defines grooves that establish fluid communication between the cavity and a space that is defined between an inner diameter of the bushing and an outer diameter of the input shaft.

A laundry treating appliance includes a tub defining a tub interior and a basket rotatably mounted within the tub interior. The basket can include an upper basket portion defining a basket interior, as well as a lower base portion coupled to the upper basket portion and including at least one spoke.

Basket for a laundry treating appliance

A laundry treating appliance comprises a rotatable basket with a spin tube, a rotatable clothes mover located within the rotatable basket, a motor having a drive shaft extending through the spin tube and operably coupled to the clothes mover, and a drive system selectively rotatably coupling the spin tube and the drive shaft and comprising a first threaded ring located about the spin tube, a second threaded ring threaded about the first threaded ring wherein at least one of the first threaded ring and the second threaded ring is axially movable relative to the other, and a gear assembly rotationally coupled to the drive shaft.

An example laundry treating appliance includes a tub, a rotatable drum disposed in the tub and defining a treating chamber in which laundry is received for treatment according to a cycle of operation, a treating chemistry dispenser having an outlet and a cup having a siphon, configured to dispense a treating chemistry into at least one of the tub or the drum, a sensor, and a controller configured to at least: introduce a predetermined amount of liquid into the cup sufficient to activate the siphon if a predetermined amount of the treating chemistry is present in the cup; detect whether the siphon activates in response to the predetermined amount of liquid based on an output of the sensor; and modify cycle of operation based on whether the siphon activates in response to the predetermined amount of liquid.

Methods and apparatus to detect treating chemistries in laundry appliances

A laundry treating appliance having a tub defining an interior, a basket located within the interior and rotatably mounted within the tub, a clothes mover rotatably mounted within the basket, a motor drivingly coupled to the clothes mover to selectively oscillate or rotate the clothes mover, and a loss motion device having a clutch configured to move among a set of indexed positions in response to rotation of the clothes mover, with the loss motion device being configured to rotationally couple the clothes mover and the basket after the clutch moves through the set of indexed positions.

Laundry treating appliance with indexing tang clutch

A method of determining load type in a laundry treating appliance having a treating chamber for receiving laundry, a rotatable laundry mover, and a motor operably coupled to the rotatable laundry mover includes steps to apply a perturbation force to the laundry in the treating chamber by rotating the laundry mover with the motor; determine the response of the motor torque to the perturbation force during the rotating of the laundry mover; and determine a load type based on the determined response.
