Latest Patents

One of his latest patents is a washer pump with a respiratory hole communicating a motor accommodating portion and the outside. This washer pump is designed to suck liquid stored in a tank and jet the liquid onto a surface for cleaning. The design includes a housing attached to the tank, an impeller that rotates within the housing, and a motor that powers the impeller. Additionally, it features a corner portion between the motor accommodating portion and the tank, along with a respiratory hole that connects the inside of the motor accommodating portion to the outside.

Another significant patent involves a washer pump that has a pair of flow paths, where the pump side of one flow path is smaller than the valve chamber side. This design integrates a pump chamber, valve chambers, discharge holes, and flow paths within a single housing. This configuration reduces the pressure loss of the cleaning liquid, enhancing the efficiency of the pump. The valve chambers extend to the discharge holes, allowing the cleaning liquid to be discharged closer to the center of the valve chambers, which minimizes turbulence and further reduces pressure loss.
