Abstract: A vacuum cleaner includes a cleaner main body including a suction motor for generating a suction force; a suction unit that is in communication with the cleaner main body and sucks air and dust; and a battery that supplies power to the suction motor. The vacuum cleaner also includes a battery management system (BMS) that detects a status of the battery; and a controller that controls an operation of the suction motor. If a voltage of the battery detected by the BMS reaches a changeable reference voltage, the controller stops the suction motor.

Abstract: A laundry treating apparatus includes a housing, which includes first and second wash units within the housing. The first and second wash unit include first and second tubs, first and second drums mounted inside the first and second tubs, and first and second drive units configured to drive rotations of the first and second drums, respectively. The laundry treating apparatus also includes a valve assembly that is configured to receive tap water and that is configured to control a supply of the tap water to each of the first wash unit and the second wash unit within the housing. The laundry treating apparatus further includes at least two supply lines configured to supply the tap water from the valve assembly to at least two supply points of the second tub in the second wash unit.

Abstract: A robot cleaner is provided that may include a suction motor installed within a main body to generate a suction force, at least two conductive plates spaced apart from each other to form a flow path for external air introduced by the suction force, and a calculator to measure a capacitance value between the at least two conductive plates. Further, provided is a robot cleaner that may include a suction motor installed within a main body to generate a suction force, a porous structure having at least one through hole, through which external air introduced by the suction force may flow, at least one filter disposed on a surface of the porous structure to filter dust contained in the air, and a power supply configured to apply alternating current (AC) power to at least a portion of the surface of the porous structure.

Abstract: A laundry machine includes first and second washing units including first and second tubs, respectively. First and second drums are mounted inside the first and second tubs, and first and second drive units drive rotations of the first and second drums around first and second rotational shafts, respectively. The second washing unit is arranged above the first washing unit and has a smaller laundry treating capacity than the first washing unit. The first rotational shaft is not parallel to the second rotational shaft. A first recess projects downward from a rear lower surface of the second tub and is configured to heat wash water in the second tub. A metal plate member is provided on an outside lower surface of the second tub, and partially extends to the rear of the second tub to expose a bottom surface of the first recess.

Abstract: A cooking appliance is provided. The cooking appliance may include a case, a top plate seated on the case, and a burner accommodated in the case. The burner may include at least one burner pot to receive a gas and air, a combustion member to burn a mixed gas of the gas and air within the at least one burner pot, a burner frame seated on the at least one burner pot to define an exhaust passage, through which the gas burned by the combustion member and carbon monoxide generated by incomplete combustion of the mixed gas may flow, and a catalyst body disposed in the exhaust passage. The catalyst body may have a catalyst to allow the carbon monoxide to react with oxygen.
