    Abstract: A cleaning device includes a suction device configured to suck a pollutant into the suction device; a body configured to collect the sucked pollutant, wherein the suction device includes: a drum rotatable around an axis and having a hollow portion, a driving motor disposed in the hollow portion of the drum and configured to apply a rotational force to the drum to rotate the drum around the axis, a rotatable chamber surrounding the driving motor and disposed between the drum and the driving motor, the rotatable chamber rotatable coaxially with the axis and configured to rotate with the drum so that a cooling fluid between the driving motor and the rotatable chamber spirals around the driving motor when the drum is rotated, and a cooling fluid discharge hole at an end of the rotatable chamber to discharge the cooling fluid outside of the rotatable chamber.

    Abstract: A vacuum cleaner operable between ON and OFF states includes a cyclonic dust separation device operable, when the vacuum cleaner is in the ON state, to provide separation of dust from an airflow through the vacuum cleaner; a motor that generates airflow through the vacuum cleaner having a motor cover provided with at least one fluid opening which defines a part of a fluid flow path for fluid originating from a serviceable filter assembly; and a valve assembly operable to open and close, respectively, the at least one fluid opening in the motor cover. The valve assembly can be configured such that, when the vacuum cleaner is in the ON state, the valve assembly is in the closed position to prevent the airflow through the at least one fluid opening, and, when the vacuum cleaner is in the OFF state, the valve assembly is in the open position to open the fluid flow path through the at least one fluid opening.

    Abstract: A motor driving apparatus for a cleaner includes a DC terminal capacitor, an inverter including switching elements configured to convert the DC power into AC power, a motor configured to operate the inverter, an impeller connected to the motor and configured to circulate air, and a printed circuit board having a first surface that mounts the switching elements and faces toward the motor and the impeller, and a second surface that mounts the DC terminal capacitor. The printed circuit board includes circuit elements mounted on a first area of the first surface and configured to carry a current having a level greater than or equal to a predetermined level. The first area is positioned in a flow path of the air circulated by the impeller.
