Abstract: The present disclosure relates to a washing machine. The washing machine includes a tub, a drum rotatably provided in the tub, and a pump for draining and circulating wash water. The pump includes a pump housing, a drain chamber formed in the pump housing, a drain pump mounted in the drain chamber and provided with a drain impeller for generating a drain pressure in the drain chamber, a first drain hose connector extending from the upper portion of the drain chamber to drain the wash water in response to rotation of the impeller in one direction, a second drain hose connector extending from the lower portion of the drain chamber to drain the wash water in response to rotation of the impeller in the opposite direction, a first drain hose connected to the first drain hose connector, and a second drain hose connected to the second drain hose connector.

Abstract: Disclosed is a method of controlling a washing machine configured such that a drum having on a front surface thereof an inlet through which laundry is put is rotatably provided in a tub containing water. The control method includes (a) a step of supplying water to submerge at least a portion of the drum in the tub; (b) a step of performing at least once an 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; (c) a step of draining the tub; (d) a step of supplying water to submerge at least a portion of the drum in the tub; and (e) a step of performing at least once an operation in which the water contained in the tub is heated by operating the heater and the drum is rotated. The step (e) includes a step of rotating at least once the drum at a second set speed which is lower than the first set speed; and a step of repeating a first drum cleaning operation in which the drum is rotated at least once at a third set speed lower than the second set speed, and a second drum cleaning operation in which the drum is rotated at least once at a fourth set speed lower than the third set speed.

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.
