Abstract: The present disclosure relates to a washing machine configured to rotate a cylindrical drum formed by processing a metal sheet about a horizontal axis. The drum includes a lifter, formed by processing the metal sheet, respectively provided at a plurality of points spaced along a circumferential direction, when viewed from a front side. The lifter includes a front lifter which is formed by protruding the metal sheet into the drum, and pressurized to be extended in a longitudinal direction of the drum, and a rear lifter disposed in a rear side of the front lifter. The rear lifter is disposed to form a certain phase angle with respect to the front lifter.

Abstract: A control method of washing machine includes: a first detection step of acquiring amount of laundry accommodated in a washing tub; a first washing step of performing washing based on a first laundry amount, when the first laundry amount acquired in the first detection step is equal to or larger than a preset first threshold value; a second detection step of, acquiring the laundry amount accommodated in the washing tub by an output of an output layer of an artificial neural network while using a current value inputted to a motor for rotating and acceleration of the washing tub as an input data of an input layer of the artificial neural network previously learned by machine learning; and a second washing step of performing washing based on a second laundry amount, when the second laundry amount acquired in the second detection step is smaller than the first threshold value.

Abstract: Disclosed is a heating circulation type drying module of a dishwasher using a fan module and PTC heaters. The dishwasher includes a cabinet defining the external appearance, a tub provided in the cabinet, a door for opening or closing the tub, a flow-path unit for circulating air inside the tub through a suction port and an exhaust port, which communicate with the tub, a suction duct for communicating with the suction port, an exhaust duct for communicating with the suction duct and the exhaust port, at least two heaters provided inside the exhaust duct for heating the air, and a fan for supplying the air to the heaters. The dishwasher may achieve improved drying performance via adjustment in the temperature of air to be discharged, and may reduce power consumption via omission of a rinsing water heating course.
