Latest Patents
One of his latest innovations is a full automatic washing machine that features a washing/drying cell rotatably mounted in an outer cell. This design includes a rotary blade unit at the bottom of the washing/drying cell, which is equipped with a cylindrical member. The washing machine motor is designed to rotate the blade unit in both forward and backward directions during washing and rinsing. Additionally, it can rotate the washing/drying cell at high speeds during the drying process. The ratio of the outside diameter of the rotary blade unit to the inside diameter of the washing/drying cell is carefully selected to range between 0.6 and 0.8, while the speed of rotation is maintained between 100 and 250 rpm. The time length of rotation for the washing machine motor in each direction is set to be less than one second.
Another significant patent is for a full automatic electric washing machine that incorporates an auto-off power source. This feature automatically switches off the machine when an abnormal washing condition occurs, allowing the operator to notice the issue during a long shelf time, such as one hour. This design ensures that the washing process can continue without the need for a reset after addressing the abnormal condition. Once the washing process is complete, the switch automatically presents an off condition after a short shelf time of five minutes, simplifying the transition to the next washing cycle.
