Abstract: An upright type vacuum cleaner having a water cleaning function comprises: a head portion having an air intake hole through which dust on a surface to be cleaned is received; a body portion rotatably installed at an upper side of the head portion and including a fan motor generating an intake force for receiving dust on the surface to be cleaned and a water pump generating a spreading force for spreading water onto the surface to be cleaned; a water cleaning unit including a washing water container storing water to be supplied to the water pump, a nozzle portion spreading water, which is stored within the washing water container, onto the surface to be cleaned with a spreading force of the water pump, a polluted water intake portion receiving polluted water on the surface to be cleaned by an intake force of the fan motor, a polluted water container storing the received polluted water, and a polluted water intake hose connecting the polluted water intake portion with the polluted water container; and a flow-pa

Abstract: A complex type cleaner comprises: a body having either a dust collecting container for storing dust and foreign materials or a water collecting container for storing contaminated water; a fan motor installed at the body and generating a suction force to suck dust or water; a suction head arranged at a lower side of the body, for sucking dust at the time of performing a vacuum-cleaning; and a suction nozzle installed at the suction head, for sucking contaminated water at the time of performing a water cleaning, wherein the water collecting container is composed of: a container mounted at the body and having a space for storing water; a cover mounted at an upper surface of the container and having an outlet for exhausting air inside the container; a division plate for dividing inside of the container into a first chamber and a second chamber, for introducing water stored in the second chamber to the first chamber when the water inside the second chamber is more than a certain level; and a water exhaustion preve

Abstract: A complex type cleaner comprises: a body having either a dust collecting container for storing dust or a water collecting container for storing contaminated water; a fan motor installed at the body and generating a suction force; a suction head arranged at a lower side of the body, for sucking dust at the time of performing a vacuum-cleaning; a water tank mounted at the suction head, for storing cleaning water to be sprayed to a region to be cleaned at the time of performing a water-cleaning; and a suction nozzle integrally formed at the water tank, for sucking water contaminated after completing the water cleaning. The complex type cleaner reduces the number of components, reduces a fabrication cost, and has a water tank of a large capacity.

Abstract: A complex type cleaner includes: a body provided with a dust collecting container for storing dust; a fan motor installed at the body and generating a suction force; a vacuum cleaning head disposed at a lower side of the body, for sucking dust at the time of performing vacuum cleaning; and a water cleaning head mounted at the vacuum cleaning head, and provided with a suction head through which contaminated water is sucked at the time of performing water cleaning and a water collecting container for storing contaminated water sucked through the suction head. As a suction nozzle for sucking contaminated water and a water collecting container for storing the contaminated water sucked through the suction nozzle are integrally formed and installed at a suction head, there is provided a complex type capable of reducing the number of parts and a production cost, and employing a small capacity fan motor.

Abstract: A complex type cleaner includes: a body provided with a dust collecting container for storing dust; a fan motor installed at the body and generating suction force; a vacuum cleaning head disposed at a lower side of the body, into which dust is sucked in case the cleaner performs vacuum cleaning; and a water cleaning head mounted at the vacuum cleaning head, for spraying cleaning water onto a region to be cleaned, sucking contaminated water after completing water cleaning, and storing the sucked contaminated water, at the time of cleaning. By implementing both a vacuum cleaning function for sucking dust and a water cleaning function in one cleaner, there is provided a complex cleaner capable of reducing the cost, increasing convenience for use, and facilitating the keeping.

Abstract: A complex type cleaner includes: a cleaner body having at least one of a dust collecting container for storing dust or foreign materials and a water collecting container for storing contaminated water; and a suction head having a dust suction opening disposed at a lower portion of the cleaner body and sucking dust when the cleaner performs a vacuum cleaning and a suction head having a suction nozzle for sucking contaminated water when the cleaner performs a water cleaning. By implementing both vacuum cleaning function for sucking dust and water cleaning function in one cleaner, a cost can be reduced, users' convenience can be improved, and the cleaner can be conveniently kept in storage.

Abstract: An upright type cleaner comprises: a body provided with a handgrip at an upper side thereof; a suction head positioned at a lower side of the body and hinge-connected to the body, for sucking dust and foreign materials of a floor; and a power ON/OFF unit disposed between the body and the suction head for turning off a power when the body is uprighted and turning on the power when the body is inclined. According to this, the power is automatically turned on without a user's additional handle at the time of performing a cleaning and the power is automatically turned off at the time of completing the cleaning, thereby increasing the user's convenience.
