A vacuum-cleaner suction tool includes a sucking portion for sucking up dust on a surface to be cleaned, a joint portion having one end connected to the upper side of the sucking portion and the other end provided with a connection pipe, and an agitator disposed within the sucking portion for scraping dust off the surface. The opening, the joint portion, and the connection pipe each have a channel portion allowing sucked-up dust to pass therethrough. The joint portion is configured to be turnable, relative to the sucking portion, in a horizontal direction substantially parallel to the surface to be cleaned to such an extent that the longitudinal central axis of the sucking portion becomes substantially parallel to the longitudinal central axis of the connection pipe, whereby the forward end of the sucking portion, from left to right, can be brought into close contact with wall surfaces so that dust liable to collect in corners can be fully sucked up.

Vacuum-cleaner suction tool and vacuum cleaner using the same

A vacuum cleaner includes an electric blower for generating a suction air flow, a suction head in communication with the electric blower for drawing in dirt, a filter bag communication with the electric blower for capturing and collecting dirt, an exhaust unit for discharging exhaust air from the electric blower to atmosphere, and an ion generator for generating negative ions and/or positive ions. The ion generator is placed between the suction head and the filter bag.

Vacuum cleaner having an ion generator

A vacuum cleaner includes a main body having an electric blower for generating a suction air flow, a dirt collecting case for centrifugally separating and collecting dirt, and a compression assembly for compressing dirt collected in the dirt collecting case to reduce a volume thereof. The dirt collecting case has a separation chamber for centrifugally separating dirt from the dirt containing air and a dirt collecting chamber in communication with the separation chamber for accumulating the dirt separated by the separation chamber. The compression assembly has a first air intake member provided in the separation chamber and communicating with the electric blower, a second air intake member provided in the dirt collecting chamber and communicating with the electric blower, a shielding plate for selectively opening the first and the second air intake member and an actuator for driving the shielding plate.

Vacuum cleaner capable of compressing dirt

A vacuum cleaner includes working elements of cleaner, that is, a blower and a dust collection unit disposed in a nozzle section of which casing is composed of an upper unit and a lower unit, and having a handle coupled to the nozzle section. At least one of the working elements is supported by the upper unit and a support unit provided in the lower unit or by the lower unit and a support unit provided in the upper unit. Therefore, the cleaner can be repaired without having all screws removed, thus repaired conveniently.

Vacuum cleaner

A vacuum cleaner includes an electric blower generating the suction force; a suction port body on which the suction force of the electric blower acts and which sucks in the dust on the surface to be cleaned; and a centrifugal force dust collection section to collect the dust from the suction port body. The electric blower includes a fan section and a low input type motor to drive the fan section.

Vacuum cleaner using centrifugal force dust collection to prevent filter blinding

An electric cleaner provided with a main body comprised of a cleaner housing ( ) equipped with wheels ( ) for mobility on a floor surface. Both side surfaces of the main body extend outwardly beyond rim portions ( ) of the respective wheels ( ) that stay in contact with the floor surface, and a center of gravity G ( ) of the main body is placed in such a position that the main body rolls toward a direction where the wheels ( ) stand on the floor surface so as to return itself into an original posture when the main body tilts in a way that one of the side surfaces lies in contact to the floor.
