  • the valve member is inserted through the drain port and disposed in the drain plug body so that the valve shaft is disposed above the support shaft. The installation of the remote-operated drain plug apparatus is thus completed.
  • a state in which the drain port is closed that is, a state in which the support shaft is lowered
  • the tip of the inner wire pushes the support shaft of the driver upward
  • the thrust lock mechanism maintains a state in which the support shaft pushes the valve shaft upward, that is, a state in which the entire valve member is lifted and the valve body moves away from the drain port so that the drain port is opened.

  • the remote-operated drain plug apparatus may be installed in some cases by providing the operating portion in a vertical wall of the washstand, instead of providing it in the overflow drain port, so that the release wire is not disposed in the overflow pipe.
  • a drain apparatus such as a tub and a washstand
  • any drain droplet that adheres to the operating portion to readily fall downward and the operating portion to be maintained in sanitary conditions.
  • the drain apparatus can be formed of the same members as those of a drain apparatus without a remote-operated drain plug apparatus and hence member management can be made more easily.
  • the present invention according to claim 1 is a remote-operated drain plug apparatus including: a drain port 1 provided in a tub; a valve member 2 disposed in the drain port 1 and opening and closing the drain port 1 when moved upward and downward; an operating portion 3 disposed in a substantially vertical wall and opening and closing the valve member 2; a release wire 4 including a tubular outer tube 4a and an inner wire 4b disposed in the outer tube 4a movably in forward and backward directions, the release wire 4 transferring operation performed on the operating portion 3 to the valve member 2.

  • the opening 7 in the operating portion 3 is located in the tub. Overflow drainage in which drain in the tub is discharged toward sewage is carried out when the water level in the tub reaches or goes beyond a fixed level in the opening 7. When the drain port 1 is open, movement of the knob 11 in one of the movable directions or associated downward movement of the action body 5 causes at least part of the opening 7 to be blocked.

Further, the other problem, in which the pressure at which the bent inner wire 4b abuts the inner surface of the outer tube 4a and the magnitude of associated frictional force increase, preventing a smooth action of the remote-operated drain plug apparatus, will not occur.
  • the interior of the operating portion body 6, which allows overflow drainage through the opening 7 and the water flow port 15, is visible when the user's line of sight is at the level of the operating portion 3.
  • the user of the tub usually views the interior of the tub obliquely downward, and the knob 11 protruding from the operating portion 3 prevents the user of the drain apparatus who views the interior of the tub obliquely downward from viewing the interior of the operating portion body 6 in the embodiment described above.
