PROBLEM TO BE SOLVED: To provide a drainage device that can be manually operated even after remote operation.SOLUTION: A drainage device 30 can open and close a drain plug 19 through direct operation of a manual switch by a user, and also can open and close the drain plug 19 via a kitchen remote controller 42 and a smart phone 43. When remote opening/closing operation is performed, a control unit 20 further drives and rotates a motor according to a position of the manual switch detected by an opening sensor and an angular position of a crank detected by an upper sensor after controlling rotational driving of the motor to complete opening and closing. Accordingly, the control unit 20 performs control not to merely stop the rotation when the opening/closing operation is completed, but to rotate the crank up to a position excluding an interference range in which there is no influence of the manual switch. |
