Description

  The present invention relates to a drain plug device having a drain plug lid for opening and closing a drain port of a bathtub.

  The remote-operated drain plug device described in Patent Document 1 is provided with an engagement mechanism that detachably engages a drain plug lid with a distal end portion of a release wire that remotely controls the drain plug. According to this drain plug device, the drain plug lid is engaged with the distal end portion of the inner wire of the release wire, thereby preventing the drain plug lid from coming off due to the opening / closing operation of the operation section.

JP 2002-88553 A

However, in this drain plug device, the drain plug lid is pushed into and engaged with the distal end side of the inner wire, so that it may not be mounted when the force for pushing the drain plug lid is weak. However, in that case, since the drain plug lid is supported on the upper end of the tip of the inner wire, the drain plug lid only rises slightly from the drain port, and the drain plug lid is not attached to the tip of the inner wire. This is difficult to see from above the bathtub. For this reason, the user may not be aware that the drain plug lid is not attached, and may continue to wastefully discharge the hot water that has been stored in the bathtub.
An object of this invention is to provide the drain plug apparatus which can visually recognize the mounting | wearing defect of a drain plug lid even if it sees from the top of a bathtub.

  In order to solve the above-described problem, the drain plug device of the present invention includes a drain plug lid that closes a drain port that discharges water from a bathtub, an operation unit that opens and closes the drain port by raising and lowering the drain plug lid, A drain plug device comprising: a transmission portion that transmits the operation of the operation portion to the drain plug lid; and an engaging portion that attaches the drain plug lid to a distal end portion of the transmission portion. An elastic body that compresses and deforms in a state where the drain plug lid is attached to the distal end of the transmission portion is disposed between the drain plug lids, and the elastic body attaches the drain plug lid to the engaging portion. The drain plug lid is floated from the transmission part when not in the state.

According to this, in a state where the drain plug lid is not attached to the distal end portion of the transmission portion, the elastic body floats the drain plug lid, so that it is easy to understand that the drain plug lid is not attached. Therefore, it is possible to detect a mounting failure of the drain plug lid at an early stage, and to prevent wasteful discharge of hot water.
In addition, since it can be seen that the drain plug lid is not installed just by looking from the top of the bathtub, it is necessary to check the mounted status of the drain plug lid by entering the bathtub or collecting water in the bathtub. Is no longer necessary. Therefore, the workability of attaching the drain plug lid is improved.
Furthermore, since the unattached state of the drain plug lid can be confirmed with a simple configuration using an elastic body, it is possible to visually recognize the poor mounting of the drain plug lid at a low cost.

  Further, the drain plug lid may have a holding portion for holding the elastic body.

  According to this, when the drain plug lid is removed from the transmission portion, the elastic body also comes off following the drain plug lid, so there is no possibility of losing the elastic body.

  ADVANTAGE OF THE INVENTION According to this invention, even if it sees from the top of a bathtub, the drain plug apparatus which can visually recognize the mounting defect of the drain plug lid can be provided.

It is sectional drawing which shows the drain plug part of the drain plug apparatus of this invention. It is sectional drawing which shows the state which closed the drain outlet in the drain plug apparatus of FIG. FIG. 2 is a cross-sectional view showing a state where a drain plug lid is not mounted in the drain plug device of FIG. 1. It is a schematic diagram which shows the outline | summary of a drain plug apparatus.

Hereinafter, embodiments of the drain plug device of the present invention will be described with reference to the drawings.
Based on FIG. 4, the outline | summary of the whole drain plug apparatus is demonstrated.
The drain plug device 20 includes an operation unit 21 provided in the rim portion of the bathtub 10, a drain plug unit 22 provided in the drain port 11 of the bathtub 10, and a transmission that transmits the movement of the operation unit 21 to the drain plug unit 22. A portion 23 and a drain plug lid 24 are provided.
The transmission unit 23 uses a release wire 231 in which an inner wire is accommodated in an outer tube so as to be able to advance and retract as force transmission means.

Next, the drain plug portion of the drain plug device will be described with reference to FIG.
In the drain plug part 22, one end of the transmission part 23 is attached to the drainage fitting 12 attached to the drain outlet 11 of the bathtub 10. A drain plug lid 24 that opens and closes the drain port 11 is attached to the tip of the transmission portion 23.

  More specifically, one end of the transmission portion 23 is a mechanical box 233 that fixes the outer tube of the release wire 231 and transmits the movement of the inner wire to the rod 232 to raise and lower the rod 232. At the tip of the rod 232, an engaging portion 232a for mounting the drain plug lid 24 is provided. Further, the drain plug lid 24 is formed with an engaged portion 24 a that is attached to the engaging portion a of the rod 232.

  Between the transmission part 23 and the drain plug lid 24, a coil spring 25 is disposed as an elastic body that lifts the drain plug lid 24 with elasticity against the transmission part 23. The coil spring 25 is compressed and deformed in a state where the drain plug lid 24 is attached to the distal end portion of the transmission portion 23, but if the drain plug lid 24 is not attached to the distal end portion of the transmission portion 23, the coil spring 25 is original. The stopper lid 24 is floated by returning to step S2.

  The upper part of the coil spring 25 is held by a holding part 24 a provided on the drain plug lid 24, and the lower part is placed on the upper part of the transmission part 23, specifically on the upper surface of the mechanical box 233. That is, when the drain plug lid 24 is removed, the coil spring 25 is also removed together. Further, the upper surface of the mechanical box 233 is a mounting surface of the coil spring 25.

  The vertical height of the coil spring 25 is set larger than the maximum protrusion amount of the rod 232 in order to float the drain plug lid 24. Further, the elastic force of the coil spring 25 can support its own weight because it floats the drain plug lid 24, and is weaker than the opening / closing force of the operation unit 21 so as not to affect the opening / closing operation and water stoppage of the drain plug lid 24. It is about the power.

  Since the coil spring 25 is placed below the drain plug lid 24 in this way, when the drain plug lid 24 is not attached to the rod 232, the coil spring 25 causes the drain plug lid 24 to be attached as shown in FIG. Float and project upward from the drainage fitting 12. For this reason, it is possible for an operator who looks at the drain plug lid 24 from above the bathtub 10 to quickly recognize that the drain plug lid 24 is not attached. Accordingly, it is possible to avoid a situation in which hot water is accumulated in the bathtub 10 with the drain plug lid 24 not attached, and water is discharged from the drain port 11 unnecessarily.

  Moreover, since the unattached state of the drain plug lid 24 can be confirmed with a simple configuration using an elastic body typified by the coil spring 25, the mounting failure of the drain plug lid 24 can be visually confirmed at a low cost. .

  Further, when the drain plug lid 24 is removed, the coil spring 25 is also removed together, so there is no possibility of losing the coil spring 25 during cleaning.

  The embodiment of the present invention has been described above. However, the present invention is not limited to this. For example, various springs other than the coil spring 25 can be used as the elastic body for floating the drain plug lid 24. Further, the drain plug lid 24 can be lifted / lowered directly by the inner wire of the release wire 231 without being lifted / lowered via the rod 232.
