PURPOSE: An ultrasonic sterilizer for a spoon and chopsticks case is provided to block bacteria from propagating by removing and externally discharging foreign materials from a spoon by attaching a piezoelectric element to the floor of a spoon and chopsticks case and vibrating water.CONSTITUTION: An ultrasonic sterilizer for a spoon and chopsticks case comprises a piezoelectric element(2-3), a spoon and chopsticks case(2-1), an upper discharge port(2-4), and a lower discharge port(2-5). The piezoelectric element generates ultrasonic wave. The piezoelectric element is attached to the floor of the case. Ultrasonic wave vibrates the water in the case and removes foreign materials from spoon and chopsticks. The foreign materials removed from the case are discharged to the upper and lower discharge ports. If the foreign materials removed are lighter than the water, for example protein, then they are discharged to the discharge port.COPYRIGHT KIPO 2012본 발명은 수저통의 위생을 청결히 함으로써 건강을 보호하게 하는 수저통에 관한 것으로 초음파 세척기의 원리를 수저통에 구현한 것이다.
