Abstract: A method for controlling a washing machine supplying water to at least a portion of the drum in the tub, performing a first operation in which the water contained in the tub is heated by operating a heater and the drum is rotated at a first set speed, draining the tub, supplying water to submerge at least a portion of the drum in the tub, and performing a second operation for heating the water in the tub by the heater and rotating the drum. The second operation includes rotating the drum at a second set speed lower than the first set speed, and repeating a first drum cleaning operation in which the drum is rotated at a third set speed lower than the second set speed, and a second drum cleaning operation in which the drum is rotated at a fourth set speed lower than the third set speed.

Abstract: A method of controlling a washing machine includes washing laundry received in the drum by water mixed with detergent, performing a spin dry operation, and performing a rinse operation. The spin dry operation includes rotating the drum at a spin dry speed to allow the laundry to rotate along with the drum without falling from a highest point of the drum, and draining water from the tub while rotating the drum at the spin dry speed. The rinse operation includes decelerating the drum from the spin dry speed to a laundry adherence speed lower than the spin dry speed, supplying a first water supply to the drum, draining the first water supply from the tub, and supplying a second water supply to the drum.

Abstract: A sensor is disclosed. The sensor according to an embodiment of the present invention may include a substrate; a first electrode pattern disposed on one side of the substrate to form a layer; a second electrode pattern disposed on the one side of the substrate to form a layer and separated from the first electrode pattern; a sensing layer located on the one side of the substrate and covering the first electrode pattern and the second electrode pattern and containing a semiconductor; a protective layer located on the one side of the substrate and covering at least a part of the sensing layer, and containing a material different from that of the sensing layer; a first electrode pad disposed on the one side of the substrate to form a layer and electrically connected to the first electrode pattern; a second electrode pad disposed on the one side of the substrate and electrically connected to the second electrode pattern; and a housing accommodating the substrate and including a filter spaced apart from the substrate, wherein the substrate includes an opening formed adjacent to an outer boundary of the first and second electrode patterns.
