Latest Patents

One of Tokuda's latest patents is an electric blower that features an electric motor comprising a stator and a rotor. This design includes an impeller that is rotated by the electric motor, with an air guide containing multiple guide blades surrounding the impeller. The casing of the blower encloses both the impeller and the air guide, equipped with exhaust openings that allow a portion of the air stream suctioned by the impeller to be discharged. The circumferential length of each exhaust opening is designed to be substantially identical to the circumferential distance between the outer peripheral ends of adjacent guide blades.

Another significant patent involves an electric blower and electric cleaner that incorporates an air-cooled power device situated between the impeller and the motor. This design features a motor unit with a stator and rotor, a fan unit with an impeller attached to the rotor's output shaft, and a circuit unit containing a heat-generating component for controlling electric power to the motor. The circuit unit is strategically placed in the airflow path of air expelled from the impeller, allowing the air to cool the heat-generating component before it cools the stator and rotor.
