Abstract: A fan motor for a vacuum cleaner includes a motor mount defining a cooling flow path inlet, an impeller, an impeller cover defining an air inlet, an air discharge opening defined at the motor mount and configured to discharge air to an outer space of the motor mount, and a cooling flow path outlet defined vertically above the motor mount. The cooling flow path inlet is configured to introduce air from the outer space of the motor mount into an inner space of the motor mount to cool the motor part, and the cooling flow path outlet is configured to discharge air from the inner space of the motor mount toward a space that is defined between the impeller and the air discharge opening based on the space between the impeller and the air discharge opening having a lower pressure than the inner space of the motor mount.

Abstract: A tower fan has a shell, and the shell has a bottom plate, an outlet structure disposed on the bottom plate, and a top plate disposed on the outlet structure. The outlet structure has a shell plate module, an inlet module, and a guiding column each made by aluminum extrusion. The inlet module is detachably mounted on the bottom plate, and the top plate is configured to engage with the inlet module. The outlet structure is modular and is made by aluminum extrusion, which not only improves efficiency and convenience of detaching the shell but also decreases difficulties and costs of manufacturing the shell. The shell of the tower fan can further have multiple outlet structures disposed in mirror symmetry and multiple fan modules each corresponding to a respective outlet structure. Tower fans with double or more air volume can be provided without making extra molds.

Abstract: In a vacuum pump in which the rotor blade in one stage has an outer diameter that is smaller at an outlet port side, or the rotor blade in one stage has an inner diameter that is larger at an outlet port side, at least one of an outer circumference portion or an inner circumference portion of the stator blade that is located immediately above the rotor blade having a smaller outer diameter or immediately above the rotor blade having a larger inner diameter has a tapered surface sloping down to an outlet port side. By providing the tapered surface, entering molecules are reflected at a right angle, sent toward an inner circumference side, and hit by the rotor blade in the upper stage. The molecules are thus sent to a next exhaustion stage.

Abstract: An internal combustion engine for an outboard motor for driving a vessel has an air guide system acting by way of a covering hood surrounding surfaces of the internal combustion engine and ancillary units. Covering hood inlet and outlet openings permit airflows to move in an interior space of the covering hood, and a fan driven by the internal combustion engine influences the airflows in the covering hood interior space. Airflows enter the interior space of the covering hood via an inlet opening and a first routing arrangement. Assisted by the fan, part of the airflows acts on the surfaces of the internal combustion engine and of the ancillary units. A second routing arrangement routs another portion of the airflows, as intake air, to an engine suction system. Airflows heated by engine and ancillary unit surfaces are conveyed by the fan and a third routing arrangement outside the covering hood.
