Latest Patents

One of Kenji Iwamoto's latest patents is for a fan that features a housing with decreased thickness portions and increased thickness portions arranged alternately in a circumferential direction. This design allows for a distance between the central axis and the edge to increase from the air inlet toward the air outlet. Additionally, the inner circumferential surface has a minimum radius smaller than the distance between the central axis and the outermost portion of the edge. At the boundary between the upper and lower housing portions, the inner circumferential surface has a radius greater than the distance between the central axis and the outermost portion of the edge. The increased thickness portions include component fastening structures that define a fastening structure arranged to fit the upper and lower housing portions together.

Another notable patent is for a ventilation fan that includes a rotor holder rotating around a rotation axis. This fan features an impeller cup with a plurality of blades on its outer circumference and a base portion that rotatably supports the rotor holder through a bearing portion. The base portion has an outer circumferential wall extending upwards in an axial direction, and a gap defining a labyrinth structure is provided between the upper end portion of the outer circumferential wall and the lower end portion of the impeller cup.
