A vacuum cleaner comprises: a body; a suction head arranged at a lower side of the body and sucking dust or filth; a suction fan mounted at the body and generating a suction force; a dust collecting container mounted in the body and collecting dust or filth sucked into the suction head; and a compression unit mounted at the body and compressing dust or filth collected in the dust collecting container.

Vacuum cleaner

A filter device for a vacuum cleaner includes a casing having a collecting space therein, a suction opening through which air including dust is sucked, formed eccentrically at one side so that sucked air can be rotated and a discharge opening through which purified air is discharged. A filter is installed at an internal space of the casing, for filtering dust from air sucked through the suction opening. A filter cleaning unit is disposed at 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. A rotation restrainer is provided for restraining rotation of the filter cleaning unit when the filter cleaning unit reaches a topmost position. Accordingly, fine dust attached to the filter in cleaning is removed so that a channel of the filter can be prevented from being closed.

A complex type cleaner comprises: a body; a suction head arranged at a lower side of the body, 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 for generating a suction force so that dust and dirty water can be sucked into the suction head; a reservoir detachably mounted at the body and storing dust or dirty water; and a valve assembly 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, the reservoir, and the suction fan. 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.

Complex type cleaner

A condensing apparatus of a washing and drying machine includes a casing that forms an accommodating space therein; a tub installed in the casing; an air duct of which one end is connected to the tub to thus introduce air into the tub; a blower fan that blows air along the air duct; and a heater that heats air of the air duct before being introduced into the tub. The condensing apparatus includes: a condensing duct of which one end is connected to a lower region of the tub and another end extends upwardly; a condensate water supplying duct connected to an upper region of the condensing duct to supply condensate water into the condensing duct; and a condensate water dispersing portion provided with a plurality of dispersion holes formed along a circumferential direction of the condensing duct with a certain interval and arranged at an outlet side of the condensate water supplying duct along a flow direction of the condensate water, to dispersedly drop condensate water supplied from the condensing water supplying duct.

A drum type washing and drying apparatus comprising: a washing unit including a tub receiving a water for washing laundry and a first drum rotatably installed inside the tub; a drying unit including a second drum rotatably installed in the vicinity of the washing unit; a first airflow duct of which one end is connected to the inside of the tub and the other end is connected to the second drum; a blowing fan installed at the first airflow duct for introducing an air inside the tub into the second drum through the first airflow duct; a heating means for heating the air passing through the first airflow duct; and a second airflow duct of which one end is connected to the second drum and the other end is connected to the tub so that the air inside the second drum is introduced into the tub therethrough, thereby improving drying performance thereof and reducing fabrication costs and noise.

Drum type washing and drying apparatus

An aeration apparatus for a combination drier and washer comprises an air circulation duct connected from one portion of a tub to the other portion for circulating air in the tub; an aeration tube connected from the air circulation duct to outside of the case for introducing exterior air; and an opening/closing unit provided at a spot where the air circulation duct and the aeration tube meet for opening and closing the aeration tube, wherein the air circulation duct is connected to a condensing water supply tube for supplying condensing water to condense water in air, and the opening/closing unit is constructed to open and close the aeration tube by condensing water supplied by the condensing water supply tube. During drying, the drying space is closed to improve drying efficiency. Afterward, air is introduced to prevent accidents.
