A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a tub and a rotatable basket within the tub. A volume of water is flows into the tub, causing a load of articles in the basket to be wetted.

A water extraction operation is performed after measuring the first weight of the load of articles. A second weight of the load of articles is measured after the water extraction operation. A load type of the load of articles is determined based on the first weight and the second weight.

Provided are a method and apparatus for determining a blockage of a filter of a clothes dryer and a clothes dryer. The clothes dryer includes a motor. The method includes following steps. An actual rotational speed of the motor is acquired, and an electrical parameter corresponding to a rotational speed range to which the actual rotational speed belongs is determined as a first threshold corresponding to the actual rotational speed; an actual clothes volume in the clothes dryer is acquired, and the first threshold is corrected according to a correction coefficient corresponding to a clothes volume range to which the actual clothes volume belongs so that a second threshold is obtained; and an actual electrical parameter of the motor is acquired, and when it is detected that the actual electrical parameter is less than the second threshold, it is determined that the filter of the clothes dryer is blocked.

A laundry treatment appliance includes a tub; a laundry basket rotatably mounted within the tub; a sensor positioned within the laundry basket; and a controller operably coupled to the sensor and configured to perform an operation. The operation includes detecting a load size of the laundry load at a completion of a recently performed washing cycle; obtaining a plurality of operational parameters from the recently performed washing cycle; determining a maximum drying cycle length of time for the laundry load based on the detected load size and the plurality of operational parameters; detecting a failure of the sensor; and directing a drying cycle according to the maximum drying cycle length of time in response to detecting the failure of the sensor.

A method and system for setting parameters of a treatment cycle in a household appliance is provided. First a model establishing a relationship between sets of configuration parameter values of achievable treatment performance is obtained. Then a target treatment performance for the treatment cycle is obtained. Values for a subset of a configuration parameter are fixed, the subset comprising at most all configuration parameters but a remaining configuration parameter. Then, a value for the remaining configuration parameter is determined. For this value, a difference between the target treatment performance and an achievable treatment performance predicted by the model using said value is below a predetermined threshold. Finally, the parameters of the treatment cycle, which can be setting parameters of the treatment cycle in the household appliance are output. The parameters comprise the determined value and the fixed values.

A method for controlling a laundry treating apparatus includes an air supplying step of supplying heated air to the drum through the heat exchange part and a first motion executing step executed while the air supplying step is in progress. The first motion executing step alternately executes a first acceleration mode of rotating the drum at an rpm inducing a centrifugal force equal to or greater than 1G along one of a clockwise direction and a counterclockwise direction and a first deceleration mode of rotating the drum at an rpm inducing a centrifugal force smaller than 1G in a direction equal to a rotational direction set for the first acceleration mode.

A washing apparatus is provided. The washing apparatus includes a main body having a door, a spin basket disposed inside the main body and rotating about a rotary shaft, a motor providing power to the rotary shaft, a spring clutch including a first core rotating in conjunction with the motor and a second core rotating in conjunction with the rotation shaft, and selectively transmitting power of the motor to the spin basket, a processor, and a sensor that measures revolutions per minute (RPM) of the spring clutch, and when the driving of the motor based on an input signal is completed, the processor controls to stop the driving of the motor, and after stopping the driving of the motor, controls the motor to be re-driven for a preset driving time based on a measurement value of the sensor.

A washing machine includes a drum, a pulsator, a motor including a stator, a first rotor connected to the drum and second rotor connected to the pulsator, an inverter circuit connected to the motor, and at least one processor configured to control the inverter circuit to selectively drive the motor based on a plurality of driving modes, the plurality of driving modes including a first driving mode to rotate only the first rotor, a second driving mode to rotate only the second rotor, or a third driving mode to rotate both the first rotor and the second rotor, control the inverter circuit to stop both the first rotor and the second rotor in response to changing from one of the plurality of driving modes to an other one of the plurality of driving modes, and control the inverter circuit to drive the motor based on the changed driving mode.

A laundry treating apparatus includes a pressure vessel configured to receive fluid and to maintain a pressure therein to be higher than an atmospheric pressure, a separator that divides the pressure vessel into a first chamber and a second chamber, a drum rotatably disposed in the first chamber and configured to accommodate laundry therein, a driver configured to rotate the drum, and a pump configured to cause the fluid to flow between the first chamber and the second chamber.

Method for controlling a spin cycle of a washing machine and washing machine comprising a suspended group (10) including a rotative drum (11) contained in a dampened enclosure (12) supported on a suspension mechanism (20), a two axes accelerometer (30) supported on the suspended group (10), the method comprises the steps of capturing and analyzing vibration data (40) relative to the vibration of the suspended group (10) detecting a vibration data variation (43) over time indicative of a weight variation of the clothes due to the loss of water and determining a stabilization of the vibration data variation (43) over time indicative of the steadiness of the weight variation of the clothes due to end of the loss of water.

A method of autonomously washing and drying at least one deformable article with a combination washer and dryer includes receiving, at a controller in communication with the combination washer and dryer, a request to begin a washing and drying cycle, instructing a pivot motor to rotate the combination washer and dryer upward such that an opening of the combination washer and dryer faces upward to receive the at least one deformable article therein; instructing the pivot motor to pivot the loaded combination washer and dryer to a washing and drying angle in a range of between about 0 degrees to 20 degrees from horizontal, and instructing, in response to a sensor output signal indicating the combination washer and dryer being pivoted to the washing and drying angle, an autonomous door loader disposed adjacent to and detached from the combination washer and dryer to seat a removable door in the opening.
