Abstract: A complex type cleaner comprises: a body (10); a suction head (20) arranged at a lower side of the body (10), for sucking dust at the time of performing a vacuum cleaning and sucking dirty water at the time of performing a water cleaning; a suction fan (12) for generating a suction force so that dust and dirty water can be sucked into the suction head (20); a reservoir (14) detachably mounted at the body (10) and storing dust or dirty water; and a valve assembly (16) for converting a cleaning mode into a vacuum cleaning mode or a water cleaning mode by selectively opening and closing passages connected among the suction head (20), the reservoir (14), and the suction fan (12). A vacuum cleaning function for sucking dust and a water cleaning function are implemented at one cleaner, thereby reducing the cost and facilitating the usage and the storage.

Abstract: A filtering device for a vacuum cleaner comprises: a casing having a collecting space therein, a suction opening through which air including dust is sucked and a discharge opening through which purified air is discharged; a filter installed at the internal space of the casing, for filtering dust from air sucked through the suction opening; and a filter cleaning unit disposed to encompass an outer circumferential surface of the filter, for cleaning the filter by being rotated by a rotation force of air sucked through the suction opening. Accordingly, the filtering device can remove fine dust attached to the filter in a cleaning operation, thereby preventing a channel of the filter from being closed with the dust.

Abstract: A filter device for a vacuum cleaner comprises: a casing (100) having a collecting space therein, a suction opening (120) through which air including dust is sucked, formed eccentrically at one side so that sucked air can be rotated and a discharge opening (150) through which purified air is discharged; a filter (300) installed at an internal space of the casing, for filtering dust from air sucked through the suction opening; a filter cleaning unit (200) disposed at an outer circumferential surface of the filter, for cleaning the filter (300) by being rotated by a rotation force of air sucked through the suction opening; and a rotation restraining means (400) for restraining rotation of the filter cleaning unit when the filter cleaning unit reaches a top dead point. Accordingly, fine dust attached to the filter in cleaning is removed so that a channel of the filter (300) can be prevented from being closed.
