The present invention relates to a washing machine configured to have a drum, into which cloth is loaded, that is rotated around a horizontal axis. The washing machine includes a plurality of protrusions which are extended in a front and rear direction on an inner circumferential surface of the drum, and are spaced along a circumferential direction, and the protrusion has a height protruding inwardly into the drum is 2.0 to 6.0% of a diameter of the drum.

A washing machine according to one aspect of the disclosure comprises: a body having a laundry input port; a water tank provided inside the body and for storing water; a drum rotatably provided inside the water tank; a pulsator provided inside the drum and rotating in the direction opposite from the rotational direction of the drum; a first motor providing a driving force to the pulsator; a second motor providing a driving force to the drum; a first inverter controlling a current applied to the first motor; a second inverter controlling a current applied to the second motor and having a temperature sensing function; and a control unit controlling the first inverter such that the rotational speed of the first motor and/or the rotation time per period of the first motor is reduced if the temperature of the second inverter reaches a predetermined first temperature.

A drive apparatus includes: a drive unit; a controller that obtains an application including a plurality of blocks, and executes the application to control the drive unit in accordance with the plurality of blocks; a first sensor; and a second sensor. Each of the plurality of blocks includes a parameter and an end condition. When, during execution of a first block, the first driving state detected by the first sensor meets the end condition of the first block and the second driving state detected by the second sensor meets a parameter change condition, the controller: changes the parameter of a second block that is executed after the first block; and controls the drive unit in accordance with the second block including the changed parameter.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A motor assembly is mechanically coupled to the wash basket for selectively rotating the wash basket and a camera assembly is mounted within the cabinet in view of the wash chamber. A controller is configured to obtain a series of image frames using the camera assembly during a wash cycle, identify a tracking point on a clothing article, generate a motion path of the tracking point over the series of image frames using an optical flow technique, estimate a turnover rate of the load of clothes based at least in part on the motion path of the clothing article, and implement responsive action in response to determining that the turnover rate falls below a predetermined threshold rate.

A method may include receiving a two-dimensional image of a laundry chamber and identifying a laundry article based on the received two-dimensional image. The method may further include selecting a prior-user profile corresponding to the laundry appliance in response to identifying the laundry article and directing a found-article message to the prior-user profile following selecting the prior-user profile.

A laundry treating apparatus may include a main body, a door, a driver, a water supplier, a drain, an internal sensor, a controller, and a display. The internal sensor may measure at least one factor from among a temperature, a humidity, and a contamination degree inside the washing tub. The controller controls operations of the driver, the water supplier, and the drain, and receives input of the at least one factor measured by the internal sensor to derive a recommended take-out time of washed laundry. The display displays the recommended take-out time derived by the controller.

A washing machine appliance includes a wash tub positioned within a cabinet, a wash basket rotatably mounted within the wash tub and defining a wash chamber configured for receiving a load of clothes, and a camera assembly positioned in view of the load of clothes. A controller is configured to obtain one or more images of the load of clothes to be washed during a wash cycle, analyze the one or more images using an image recognition process to identify an outlier garment in the load of clothes, determine that the outlier garment is not on a safelist, and implement a responsive action in response to identifying the outlier garment that is not on the safelist.
