Abstract: A suction hose assembly for an upright type vacuum cleaner having an air inlet connected to one end of a flexible hose and a suction pipe at the other end. A connection portion movably connects the suction pipe to the flexible hose allowing the suction pipe to rotationally rotate relative to the flexible hose, including a pair of connection protrusions preferably formed on one end of either the suction pipe or flexible hose, and spaced from each other by a predetermined distance, a pair of connection grooves formed on one end of whichever the flexible hose or suction pipe that the connection protrusions are not formed on, to receive the pair of connection protrusions, and at least one guide protrusion provided between a contact surface defined between the connection protrusions and a contact surface defined between the connection grooves, to reduce area of contact defined between the contact surfaces.

Abstract: A suction hose assembly for an upright type vacuum cleaner including a flexible hose connected to an air inlet of a cleaner body with one end thereof, a suction pipe connected to the other end of the flexible hose with one end thereof and connected to an extension hose of the suction brush with the other end thereof, and a connection portion for movably connecting the suction pipe to the flexible hose so that the suction pipe can rotate relative to the flexible hose in a rotational direction.

Abstract: A suction brush rotatably disposed at a cleaner body to move along a cleaning surface for drawing in contaminants from the surface to be cleaned by a suction force generated from a motor driving chamber disposed at a lower portion of the cleaner body having a suction brush body, a brush bar rotatably disposed inside the suction brush body, for brushing the contaminants off from the surface to be cleaned, a driving force transmission belt disposed inside the suction brush body for transmitting a rotation force to the brush bar from a motor disposed in the motor driving chamber, and a belt checking cover pivotably disposed at a lower portion of the suction brush body to check the condition and contamination of the driving force transmission belt.

Abstract: An upright vacuum cleaner comprises a cleaner body pivotably connected to a suction port assembly, plural locking recesses formed in a side of the cleaner body, and a resilient pedal pivotably mounted on the suction port assembly, and having a locking protrusion which is sequentially locked in the one or more locking recesses when the cleaner body rotates. The locking recesses comprise a parallel position recess in which the locking protrusion is locked when the cleaner body rotates to a parallel position with respect to a surface to be cleaned. Accordingly, even when the cleaner body is in a position parallel to the surface to be cleaned for a long time, the resilient support portion of the resilient pedal is prevented from being deformed permanently.

Abstract: An air exhaust structure for an upright-type vacuum cleaner capable of a convenient use by providing a filter cover which is not easily opened by a discharging pressure of the air, while the filter cover is easily opened and closed by the user. The air exhaust structure of an upright-type vacuum cleaner has a frame having a duct formed at a side of the cleaner body to communicate with the motor driving chamber, a support member protruded from an inside wall of the duct, a filter, a filter cover having a grill portion disposed at the frame; and a removable means for opening and closing the filter cover. The removable means includes a hook formed at a front end of the filter cover and a locking hole having a locking protrusion disposed at the frame placed at a corresponding position of the hook.

Abstract: A filter supporting structure for an upright-type vacuum cleaner having a body divided by a partition into a dust-collecting chamber having a dust bag and a motor driving chamber, a filter grill formed at the partition in order to allow an air passed through the dust bag of the dust-collecting chamber to flow to the motor driving chamber, and having a filter for filtering the drawn air, supporting protrusions disposed at both sidewalls of the dust-collecting chamber in order to support both sides of the filter mounted on the filter grill, and a plurality of ribs disposed around the filter grill in order to support the filter.

Abstract: An air flow structure for an upright-type vacuum cleaner having a body divided by a partition into a dust-collecting chamber having a dust bag and a motor driving chamber having a motor; an air suction port protruded at an upper part of the dust-collecting chamber in order to draw air thereinto, and having the dust bag disposed around the air suction port; a dust cover to cover the dust-collecting chamber and having a plurality of ribs disposed therein in a lengthwise direction, a concaved portion formed at a rear wall of the dust-collecting chamber in a lengthwise direction, and a grill portion formed between the dust-collecting chamber and the motor driving chamber in order to allow the air of the dust-collecting chamber to flow to the motor driving chamber.

Abstract: A dust cover sealing apparatus of a vacuum cleaner comprises a first fence protruding from an edge of a dust collecting chamber and having a predetermine height, and a second fence protruding from an inner surface of the dust cover to contact an end of the first fence when the dust cover is mounted on a cleaner body, and a plurality of guide ribs protruding from an inner surface of the dust cover adjacent to a side of the second fence, for guiding the second fence so that ends of the first and second fences contact each other when the dust, cover is mounted on the cleaner body. Accordingly, the sealing efficiency of the dust collecting chamber is maintained, and the manufacturing cost is reduced.
