The diffuser is in fluid communication with the suction source for diffusing the suction airflow and the diffuser includes a circumferential opening that surrounds the suction source such that the suction airflow travels through the opening into the diffuser. The duct is located downstream of the blower port with respect to the direction of the suction airflow and the duct includes an outlet. The cap is removably coupled to the blower port such that at least a portion of the suction airflow exhausts through the blower port when the cap is removed, and when the cap is coupled to the blower port the suction airflow is travels through the duct and exhausts through the outlet.

An electric powered work machine according to one aspect of the present disclosure includes a first and a second digital filters, a control sound source, an error sensor, and a characteristics adjustor. The first digital filter includes a series of taps and generates a control signal. The control sound source produces an artificial noise in accordance with the control signal. The error sensor converts a synthesized sound of the artificial noise and a target noise at a canceling location to an error signal. The second digital filter includes N taps and generates a filtered reference signal. The characteristics adjustor uses the error signal and the filtered reference signal to adjust a coefficient of each tap of M taps in the series of taps. Each of M and N is a positive integer satisfying M<N.

A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

A cyclone unit capable of enhancing dust collection performance. A cyclone unit includes a cyclone unit body, a dust box and a core tube. The cyclone unit body includes a lower base, an upper base and a middle base sandwiched between the lower base and the upper base. The dust box is assembled to the cyclone unit body so as to collect dust and dirt. The core tube, having a meshed shape, is assembled to the middle base so as to be located inside the dust box. The core tube is detachable from the middle base while the upper base is assembled to the lower base.

A cleaner includes a hollow cylindrical housing; a housing wall dividing an internal space of the housing into a first space and a second space; a wall through-hole defined to pass through the housing wall; a mounting portion including a mounting body having a top face and a mounting space defined therein in communication with the second space, the mounting body being fixed into the wall through-hole; first openings defined in a first region of the bottom face, and second openings defined in a second region of the bottom face; a separator disposed in the first space to form a flow path for guiding air to the plurality of openings, and a filter that includes a filter body located in the mounting space, and filter faces to filter the air flowing through the first openings and second openings.

A disassembly mechanism configured to be disposed on a dust collector is provided, including: a fixation assembly, including a first fixation portion and a second fixation portion, the first and second fixation portions being configured to be disposed on a base and a barrel of the dust collector respectively, the second fixation portion including a slot; an actuating mechanism, including an engaging portion being disengageably engaged laterally with the slot and a connecting portion being movably disposed on the first fixation portion, and the engaging portion being movable with the second fixation portion. A dust collector including at least one aforementioned disassembly mechanism is also provided.

The present application relates to a cleaning appliance including: a hollow cylindrical housing; a housing wall dividing an internal space of the housing into a first space and a second space; a wall through-hole defined to pass through the housing wall; an intake port communicating the first space with an exterior of the housing; an exhaust including a cover through-hole and an exhaust hole defined to pass through a top face of the housing; a fan fixed to the wall or the second space and positioned in the wall through-hole, wherein the fan flows air in the first space to the exhaust hole; a separator disposed in the first space to form a flow path for guiding air flowed into the intake port to the fan, wherein the separator separates a foreign matter from the air using a centrifugal force; and a display including: a display panel exposed to the exterior of the housing through the cover through-hole; a display housing fixing the display panel thereto; and a housing fastening portion for fixing the display housing to the wall or an inner circumferential face of the housing.

A cleaner is disclosed. The cleaner may include a housing having an opening through which air is introduced into the housing. The cleaner may also include a filtering unit mounted in the inner space of the housing. The filtering unit may define a dust collection space between the filtering unit and the inner surface of the housing. In addition, the cleaning unit may be mounted to surround the filtering unit. A manipulation unit may raise or lower the cleaning unit within the dust collection space. Furthermore, brush protrusions may protrude from the cleaning unit toward the surface of the filtering unit.

A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member extends from the cyclone air inlet end of the cyclone chamber towards an openable bottom end of the cyclone chamber. The physical filtration member comprises a conical section which decreases in diameter towards the openable bottom end of the cyclone chamber, wherein a projection of the conical section meets at a location that is positioned between the physical filtration member and the openable opposed end. An openable bottom end of the cyclone bin assembly and the openable bottom end of the cyclone chamber are openable concurrently.
