Latest Patents
Yoshitake Sumida holds a patent for a unique dishwasher design that utilizes a two-step washing process. In the first step, tableware is washed within 10 minutes using acid ionized water with a pH value of at most 6.0 and a temperature of at least 40°C. This method helps dirt to form cohesion and prevents it from reattaching to the tableware, thereby reducing the washing load in subsequent steps. The second step involves washing the tableware for at least 15 minutes with alkaline ionized water, which has a pH value of at least 8.5 and a temperature of at least 55°C. This approach significantly improves the washing effects on fats, oils, proteins, and starches. Additionally, the simultaneous production of both types of ionized water allows for efficient use without the need for multiple water tanks, leading to reduced dishwasher size and manufacturing costs. This innovative design also promotes water conservation.
