Abstract: A cyclone type dust collecting apparatus for a vacuum cleaner with a cyclone body comprising an air inlet port and air discharge port, which forms a cyclone stream in air including dusts drawn in through the air inlet port. A dust collecting receptacle is removably connected to the cyclone body for collecting dust separated from air by the cyclone stream. A grill assembly is disposed at an end of the air discharge port inside the cyclone body for preventing dust from flowing back through the air discharge port of the cyclone body, and a fine dust filtering means is disposed at a downstream end of the grill assembly of the cyclone body for separating fine dusts which has not been separated by the grill assembly.

Abstract: A convertible vacuum cleaner has a nozzle comprising a suction port; a cleaner body having a filter housing in which a filter is mounted, and a motor housing in which a motor is mounted, the cleaner body for being removably connected with the nozzle, the suction port being connected with the filter when the cleaner body is connected with the nozzle; a locking member slidably disposed on a side of the nozzle; a slot formed in the motor housing for receiving the locking member and thereby preventing the cleaner body from separating from the nozzle; and a unlocking means for sliding out the locking member from the slot. By sliding the locking member, which is slidably disposed in the nozzle, into or out from the slot of the cleaner body, the nozzle and the cleaner body can be connected or disconnected simply.

Abstract: A grill assembly for a cyclone dust collecting apparatus for use in a vacuum cleaner capable of improving dust collection of the vacuum cleaner by preventing dirt from flowing into a vacuum-generating device after passing through a grill. The grill assembly is disposed at an upper part of an air discharge passage of a cyclone body for separating dirt from a whirling air current by centrifugal force by forming the whirling air current from drawn air, and the grill assembly prevents dirt from being drawn into the vacuum-generating device of the vacuum cleaner. The grill assembly comprises a grill body having a plurality of passages formed thereon and filtering units disposed along an interior wall of the grill body for filtering dust drawn into the grill body through the plurality of passages.

Abstract: A discharging duct of an upright-type vacuum cleaner having side walls and a pair of ribs defining a passage portion, the passage portion connecting an air outlet pipe and a motor driving chamber of a cleaner body. A cover is connected to the duct and seals the passage portion. The cover includes side walls and sealing strips integrally formed thereon to tightly contact the ribs, the sealing strips completely contacting an outer surface of the ribs. Accordingly, the contact area of the cover with respect to the ribs of the duct is lengthened, and sufficient sealing effect is guaranteed without having to use a separate sealing member. Since the need for a separate sealing member is eliminated, the duct is easier to assembly and less costly to manufacture.

Abstract: A cyclone dust collecting apparatus has: a cyclone body; a suction pipe extended to be protruded into the cyclone body by penetrating one side of the cyclone body in order to guide an air, which has been drawn into through a suction unit, into the cyclone body; a discharge pipe for guiding a clean air centrifugally separated in the cyclone body to an outside of the cyclone body; and a guide member for guiding the air, which whirls along a side wall of the cyclone body after being drawn into through the suction pipe, to a lower side of the suction pipe. According to the cyclone dust collecting apparatus of the present invention, a deterioration of suction force of the cyclone dust collecting apparatus is prevented, and thus a dust collection efficiency of the cyclone dust collecting apparatus will be improved.

Abstract: A vacuum cleaner brush having a case and a rotary element on which a floor cloth is attached. The rotary element is rotatably disposed on a lower portion of the case. A housing is disposed in the case, having a motor disposed therein, the motor rotatably driving the rotary element. A first and second bushing into which the driven shaft of the rotary element is provided with a blocking element protruding from a bottom surface of the case in the shape of a cylinder along a circumference of the first bushing for preventing dust and dirt from flowing into the first bushing. A ring element protrudes from an upper and inner circumference of the first bushing toward an outer circumference of the driven shaft, the ring element prevents dust and dirt from flowing into the housing. Dust and dirt are thereby prevented from flowing into the housing and damaging various components such as the motor and gears in the housing.

Abstract: A suction port assembly of a vacuum cleaner. The suction port assembly has a pair of suction paths formed at a front and a rear portions of a bottom of a suction port body, respectively, so as to enhance the cleaning efficiency, and due to a presence of an elastic member formed at a front edge of the suction port body as shock-buffering means, the reduction of the durability incurred by the collision with an external obstacle is prevented. Meanwhile, in case that a floorcloth is rotatably disposed on a lower surface of the bottom of the suction port body, since the suction port assembly further includes a floorcloth cover protruding from the bottom of the suction port body toward a cleaning surface, the safety of a user is guaranteed.

Abstract: A suction nozzle unit for a vacuum cleaner unit includes a casing formed with a suction inlet, a pair of front wheels located at the front of the casing, and a pair of rear wheels located at the rear of the casing. The suction nozzle unit also includes a shaft pin for rotatably supporting the front wheels and an arrangement, for moving the casing up and down relative to the shaft pin so as to raise and lower the front end of the casing relative to the surface to be vacuumed. As a result the front end of the unit can be moved up and down as necessary depending, for example, on the depth of pile of a carpet being vacuumed, thereby increasing ability of the unit to travel over the carpet during vacuuming.
