The vacuum cleaner comprises a main body having a suction port and a discharge port, a suction unit having a dust collecting port and a discharge opening, and on which the main body is rotatably installed, a handle installed to the main body, an extension pipe disposed between the handle and the main body and having a hollow inner space to define a flow passage for foreign substances, a securing mechanism between the extension pipe and the main body to restrict a circumference of the extension pipe, a cover installed at a portion of the main body where the securing mechanism and a lower end of the extension pipe are disposed, and an attaching mechanism between the securing mechanism and the cover to allow the extension pipe to be detached from the securing mechanism.

Abstract: Disclosed herein is a main body mounting structure of an upright type vacuum cleaner capable of being converted to a canister type. The mounting structure comprises a main body having a suction port and a discharge port formed thereon and including a suction device inside the suction port, a connection panel on which the main body is detachably installed, a suction unit having a dust collecting port and a discharge opening and on which the connection panel is rotatably installed, an attaching mechanism disposed between the main body and the connection panel, an extension pipe and a handle detachably installed to the main body and having a hollow inner space to define a flow passage along which foreign substances are induced, and a suction hose connected at one end with the suction port and selectively connected at the other end with the discharge opening or the handle.

Abstract: Disclosed herein is an angle control apparatus for an upright type vacuum cleaner. The angle control apparatus comprises a main body having a suction port and a discharge port formed thereon and including a suctioning device inside the suction port, a suction unit having a dust collecting port and a discharge opening and on which the main body is rotatably installed, a suction hose made of an elastic material and positioned between the suction port and the discharge opening, and a locking assembly installed to the suction unit to restrict rotation of the main body. With the angle control apparatus, the main body of the vacuum cleaner is rotatably coupled to the suction unit such that the main body is rotated at a suitable angle with respect to the suction unit sliding on a floor according to a location of a user during the cleaning operation, thereby enabling a convenient cleaning operation.

Abstract: Disclosed herein is a vacuum cleaner. The vacuum cleaner includes a dust container having an air inlet and an air outlet, a filter inside the dust container, a case part on the filter, a dust removing part rotated inside the filter while contacting the filter, and a drive unit rotating the dust removing part. The dust removing part removes dust from the filter while being rotated by air, thereby preventing the filter from undergoing functional deterioration.

Abstract: Disclosed herein is a vacuum cleaner. The vacuum cleaner includes a dust container having an air inlet and an air outlet, a filter inside the dust container, a case part on the filter, and a dust removing part contacting an inner side of the filter while being rotated by air introduced into the dust container through the air inlet. The dust removing part dislodges dust from the filter while being rotated by the air, thereby preventing the filter from undergoing functional deterioration.

Abstract: Disclosed herein is a handy cleaner-integrated vacuum cleaner. The vacuum cleaner includes a main body having a body inlet, a body outlet and a mounting part, and accommodating a motor assembly to induce air into the main body through the body inlet and then to discharge the air through the body outlet, a dust container mounted on the mounting part to filter foreign matter from air, a driving unit mounted on the mounting part and coupled to the dust container to generate a suction force in the dust container when the dust container is detached from the main body, and a power supply device to supply electrical power to the driving unit. The vacuum cleaner allows vacuum cleaning without a separate handy cleaner even in a narrow space, and provides an improved battery-mounting structure to allow convenient recharge and replacement of the battery, and a convenient repair.

Abstract: Disclosed herein is a handy cleaner that can be converted into a canister type vacuum cleaner. A vacuum cleaner includes the handy cleaner. Further, a handy cleaner-integrated vacuum cleaner has an improved dust container-mounting structure to allow convenient conversion into a handy cleaner, and an improved suction path structure allow convenient accommodation of the handy cleaner. The handy cleaner includes a dust container having an intake port and an exhaust port to allow circulation of air therethrough and including a filter disposed in the dust container to separate foreign matter from the air, and a driving unit detachably mounted to the dust container to generate suction force in the dust container and including a suction duct communicated with the intake port and an exhaust opening communicated with the exhaust port.

Abstract: Disclosed herein are a vacuum cleaner capable of being converted into a handy cleaner, and a handy cleaner-integrated vacuum cleaner. The vacuum cleaner includes a main body having a body inlet, a body outlet and a mounting part, and accommodating a motor assembly to induce air into the main body through the body inlet and then to discharge the air through the body outlet, and a dust container mounted on the mounting part to filter foreign matter from air which enters the main body through the body inlet; wherein the mounting part comprises a first mounting part on which the dust container is detachably mounted, and a second mounting part constituting an accommodation space. The handy cleaner-integrated vacuum cleaner includes an accommodation part formed on the main body to receive various kinds of nozzle, which will be connected to the body inlet.

Abstract: A vacuum cleaner includes a dust container detachably mounted in a body of the vacuum cleaner and configured to perform vacuum cleaning via air suction even in a detached state. The vacuum cleaner includes the body having a hose attaching part and an accommodation recess, the dust container separably inserted into the accommodation recess, and including a hose mounting port, a filter, a knob, and a coupling part formed near the filter on an outer surface of the dust container, a main motor received near the filter of the dust container in the body and driven to suck air, a power supply device to supply power to drive the main motor, and an assistant driving unit separably inserted into the accommodation recess, and including a fastening part releasably coupled to the coupling part and an assistant motor received in the assistant driving unit to suck air.

Abstract: An versatile vacuum cleaner is disclosed which comprises a main body, a socket, a first cleaner, a second cleaner, a motor assembly, a cord reel, a handle, and an exhaust duct, and can be converted easily into different configurations each suitable for a specifically different type of vacuum cleaning operation.
