WASHING DEVICE FOR DRAINING SECTION OF SINK

摘要

PROBLEM TO BE SOLVED: To provide a washing device for a draining section of a sink capable of easily removing dirt sticking to the draining section of the sink. SOLUTION: A mesh cage 21 and a drain trap 22 are fitted into the drain opening 20 opened on the bottom face 1a of a sink to form a washing device of the draining section 2 of the sink 1. A water supply passage 3 communicating with the drain section 2 at the lower stream end is provided. A water supply valve 30 opening/closing the water supply passage 3 is provided. And a drain valve 40 opening/closing the drain pipe 4 of the downstream side of the drain section 2 is provided. An ultrasonic oscillator 5 is installed in the inside wall of the drain section 2. The drain valve 40 is closed by the user's in-operation of the operation part 6 and the water supply valve 30 is opened to pour water into the drain section 2. The ultrasonic waves are oscillatedto the water by the ultrasonic oscillator 5 to wash the drain section 2 by ultrasonic oscillation. After a specified time, the oscillation of the ultrasonic waves is stopped to open the drain valve 40 by a controller 7. COPYRIGHT: (C)2005,JPO&NCIPI
