Latest Patents

One of his latest patents involves an axial fan that includes an impeller cup with a blade extending in a radial direction. This design features a motor configured to rotate the impeller cup, along with a housing that accommodates both the impeller cup and the motor. The housing consists of a casing portion that covers the outer periphery of the impeller cup, a base portion that supports the motor, and a spoke portion connecting the base and casing portions. Notably, a vibration restraining portion is integrated into the outer peripheral portion of the base, which has lower stiffness than other sections.

Another recent patent also focuses on an axial fan, which includes a plurality of blades designed to produce an air current flowing from the inlet side to the outlet side. In this design, the blade features a curved portion that rises toward the inlet side along its outer peripheral edge. The starting position of this curved portion delineates a convex curve that protrudes radially outward, and specific relationships between the lengths of the curve are defined to optimize performance.
