A washing machine includes a drum, a drum motor coupled to the drum; a driving circuit and a processor. The driving circuit is configured to supply a driving current to the drum motor so that the drum motor rotates. The processor is configured to control the driving circuit to accelerate the drum motor from the first rotational speed to a second rotational speed based on a gradient of the fluctuating magnitude of the driving current supplied to the drum motor while controlling the driving circuit to rotate the drum motor at a first rotational speed.

Laundry treating appliance and methods of operation

Methods of reducing a likelihood of contact between a rotating laundry-container, such as a basket or drum, located within a tub of a laundry treating appliance where the method includes rotating the drum during a measurement period, determining a torque, speed, acceleration, and position of the drum, using a parameter estimator to estimate the position of a mass relative to an imbalance of laundry and accelerating the rotation of the drum when the mass is determined to be angularly spaced from the relative position of the imbalance of laundry.

WASH ARTICLE ENTRAPMENT DETECTION FOR LAUNDRY WASHING MACHINES

A method for detecting entrapment of an article between a laundry machine door and bellows, comprising: identifying a maximum startup motor torque value of the drum motor while accelerating the drum from a stop to a target rotation speed; identifying a maximum operating motor torque value while rotating the drum at the target rotation speed; comparing a difference between the maximum startup motor torque value and the maximum operating motor torque value to a predetermined torque difference value; and terminating operation if the difference exceeds the predetermined torque difference value. A laundry washing machine configured to perform the method is also provided.

WASH ARTICLE ENTRAPMENT DETECTION FOR LAUNDRY WASHING MACHINES

A method for detecting entrapment of an article within a laundry washing machine. The method includes rotating the drum to a target rotation speed, determining a respective drum motor torque value for each rotation, determining a distribution characteristic value of the drum motor torque values, comparing the distribution characteristic value to a predetermined threshold value, performing a correction operation to address an entrapment condition upon determining that the distribution characteristic value is above the predetermined threshold value, and proceeding with the laundry washing cycle upon determining that the distribution characteristic value is below the predetermined threshold value.

METHOD FOR IMPROVED TUMBLING OF CLOTHES IN A WASHING MACHINE APPLIANCE

A method of operating a washing appliance includes obtaining images of a wash chamber using a camera assembly while the wash basket is tumbling a load of clothes positioned therein. The one or more images are analyzed using a machine learning image recognition process to determine a tumble condition of the load of clothes in the wash basket, e.g., whether the clothes are tumbling in the wash basket in a manner that generates suitable mechanical washing action. The motor assembly is then used to adjust a basket speed based at least in part on determining that the tumble condition deviates from a target tumble condition.

AUTONOMOUS LAUNDRY WASHING AND DRYING DEVICES, SYSTEMS, AND METHODS OF USE

An autonomous system for washing and drying household laundry includes a plurality of autonomous combination washer and dryers each including a perforated drum disposed within a tub mated thereto at a drive end opposite an opening. A first air orifice is disposed through the tub. A detachable door includes a second air orifice configured to receive an air conduit such that air flows through the first and second air orifices during a drying cycle while the door seals the opening. A controller is configured to instruct a drive motor to spin the drum about a spin axis extending between the drive end and the opening. A driven carrier in operable communication with the controller slides along a raised rail disposed adjacent the plurality autonomous combination washer and dryers and retrieves, holds, and reseats a door in an opening of one of the plurality of autonomous combination washer and dryers.
