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.

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.

A driving device for a washing machine includes: a shaft including an inner shaft and an outer shaft surrounding the inner shaft; a motor assembly including a stator, a rotor that surrounds the stator, a modulator that surrounds the rotor, and a magnetic gear rotating body that surrounds the modulator; a first fixation body that connects between the inner shaft and the magnetic gear rotating body; a second fixation body having one end connected to the stator and the other end connected to a tub; and an electronic clutch that disconnects the outer shat and the rotor or connects the inner shaft and the rotor according to an operation mode of the washing machine. The modulator adjusts a speed and torque of the magnetic gear rotating body. The driving device may make a motor drive area highly efficient and may reduce electric consumption.

A laundry treating apparatus includes a body provided with a laundry inlet; and a door configured to open or close the laundry inlet, wherein the door includes a door frame having a first opening portion facing the laundry inlet and a second opening portion corresponding to a display module mounted at an inside in a state that the door is closed; and a door cover coupled to the door frame to form an appearance of the door, the door cover includes a non-light-transmitting region, and a first light transmitting region corresponding to the first opening portion and a second light transmitting region corresponding to the second opening portion within the non-light-transmitting region, and a mounting guide for an alignment between the first opening portion and the first light transmitting region and an alignment between the second opening portion and the second light transmitting region is provided on at least one of the door frame and door cover during mutual coupling.

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.

A washing machine includes a water tank provided to store washing water in a cabinet, a rotating tub rotatably provided in the water tank, a pulsator provided in the rotating tub and rotated by a washing shaft, a driving motor configured to generate a rotational force for rotating the washing shaft, a clutch configured to selectively transmit the rotational force generated by the driving motor to a dewatering shaft for rotating the rotating tub and includes a housing through which the washing shaft and the dewatering shaft pass, a pulley including a first pulley rotated by the driving motor and a second pulley connected to the washing shaft, is connected to the first pulley by a belt, and configured to rotate the washing shaft, a bracket coupled to the second pulley and to which magnets are fixed, and a sensor unit coupled to the housing and configured to detect the number of rotations of the driving motor by detecting the magnets.

Disclosed herein is a laundry machine. More particularly, a laundry machine for generating steam by an induction heater and a control method thereof are disclosed. According to an embodiment, the laundry machine may include a tub, a drum rotatably arranged in the tub to accommodate an object and provided with a through hole on an outer circumferential surface, an induction heater provided to the tub and configured to heat a heating surface of the drum opposing the induction heater on an outer surface of the drum, a motor driven to rotate the drum, a spray nozzle configured to spray water onto the heating surface of the drum opposing and heated by the induction heater to generate steam, and a processor configured to rotate the drum such that the steam is introduced into the drum through the through hole of the drum in a space between the tub and the drum.

A washing apparatus is provided. The washing apparatus includes a tub, a drum configured to be rotatable in the tub, a pulsator configured to be rotatable in the drum, a driver configured to drive the drum and the pulsator, and a controller configured to control the driver to rotate the pulsator to a second direction while rotating the drum to a first direction. The controller controls the driver to drive the pulsator based on a position of laundry accommodated in the drum during a rotation of the drum.
