Title:
DRAIN PLUG SYSTEM
Document Type and Number:
Japanese Patent JP2023065733
Kind Code:
A
Abstract:
To provide a drain plug system capable of suppressing an increase in costs related to production, maintenance, and the like.SOLUTION: A drain plug system 1 comprises an operation part 34 for switching an open/closed state of an exhaust port 102, and has an automatic closing function for automatically switching the exhaust port 102 from an open state to a closed state by controlling operation of a motor 32a. Then, the automatic closing function is switched between valid and invalid when a detection part 6 detects a preset specific operation in the operation part 34. In this manner, it is no longer necessary to separately provide a device for switching between enabling and disabling the automatic closing function since it is possible to switch between valid and invalid of the automatic closing function by effectively using the operation part 34 that is an operation target when opening and closing the exhaust port 102. As a result, it is possible to suppress an increase in costs related to production, maintenance, etc. of the drain plug system 1.SELECTED DRAWING: Figure 1
