20220372684 · 2022-11-24 ·

The present invention relates to a washing machine and a spin-drying control method for the same, the washing machine including an inner tub, a drain pump, a motor and a control unit that controls the drain pump and the motor and carries out a spin-drying cycle including a sub spin-drying cycle and a main spin-drying cycle. The control unit changes a preset rotation time of the inner tub in the main spin-drying cycle according to the rotation speed of the inner tub during the sub spin-drying cycle, or determines whether to change the spin-drying time of the main spin-drying cycle according to a current value of the drain pump during the main spin-drying cycle, thereby improving spin-drying efficiency.

Optimizing soak time in a washing machine appliance

A method of operating a washing machine appliance is provided. The washing machine appliance includes a rotatable basket and a motor configured to drive the rotatable basket. The method includes sensing an attribute of articles in the basket. The method also includes determining a pause duration for an agitation operation based at least in part on the sensed attribute of the articles in the basket. The method further includes performing the agitation operation for a period of time. The agitation operation includes activating a motor of the washing machine appliance to agitate the articles within the basket for an agitation duration and deactivating the motor of the washing machine appliance for the pause duration. The period of time is equal to the sum of the agitation duration and the pause duration.

FOREIGN PARTICULATE ALGORITHM FOR A LAUNDRY APPLIANCE

A laundry appliance includes a cabinet having a user interface. A drum is disposed within the cabinet and is operably coupled to a motor that rotates the drum. A blower delivers process air through an airflow path that includes the drum. A controller is communicatively coupled to the user interface, the motor, and the blower. The controller is configured to selectively operate a foreign particulate cycle that includes at least a soft-start feature.

WASHING MACHINE VENTILATION SYSTEMS AND METHODS

Washing machine appliance ventilation systems and methods include rotating a wash basket of the washing machine appliance for an ON period, whereby a flow of ambient air is drawn through an aperture in the washing machine appliance from an ambient environment into the wash basket. The systems and methods also include comparing a humidity within the washing machine appliance to a reference humidity value. When a difference between the humidity within the washing machine appliance and the reference humidity value is greater than a threshold, the step of rotating the wash basket for the ON period is repeated. When the difference between the humidity within the washing machine appliance and the reference humidity value is less than or equal to the threshold, the ventilation cycle or method is terminated.

CLOTHES TREATING APPARATUS AND CONTROL METHOD THEREOF

The present disclosure relates to a clothes treating apparatus including a drum, a door to open and close the drum, an opening/closing switch to output a signal in response to opening or closing of the drum by the door, a motor to rotate the drum, a controller to generate a control command for controlling a rotational speed of the motor, a driving device including an inverter to convert power applied to the motor and an inverter driver to output a control signal of the inverter in response to the generated control command, and a protection switch connected between the opening/closing switch and the inverter driver to be turned on or off by the signal output by the opening/closing switch, wherein the inverter driver turns off the inverter when a voltage applied by the protection switch is less than or equal to a reference voltage.

Method for controlling washing machine

A method of controlling a washing machine that includes a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine, the method including: operating the washing motor to rotate the drum in a first rotational direction while repeatedly alternating between an acceleration and a deceleration of the drum so that laundry in the drum alternates between maintaining contact with an inner surface of the drum during acceleration, and separates from the inner surface of the drum during deceleration; and operating a circulation pump motor in the circulation pump, while the drum rotates in the first rotational direction, to accelerate a pump speed of the circulation pump during the acceleration of the drum, and to decelerate the pump speed during deceleration of the drum.
