[0029]
In this configuration, when hot water is poured into the bathtub 10 for bathing, first, the operation switch 14 is pressed to activate the drive device, thereby lowering the drain plug 11. As a result, the drain plug 11 is in the state indicated by the solid line in FIG. 2, and the drain port 17 is closed. Next, the hot water supply operation section 13a and the water supply operation section 13b of the faucet 13 are adjusted to be opened and closed, and hot water of an appropriate temperature is put into the recess 10a. To do.
[0030]
When hot water or water is used after washing the hair or body at the washing place, the hot water or water after use flows from the hole of the drain port member 32 into the drain pipe 24, and the drain pipe. 24 is discharged to the outside. In addition, when hot water or water enters the bathtub side floor 20 side, the hot water or water flows into the drain pipe 24 from the drain hole 48 and is discharged to the outside in the same manner as hot water or water at the washing place. In this case, the float valve 41 moves to the position indicated by the solid line in FIG.
[0031]
When the hot water or water in the recess 10a is discharged after bathing, the operation switch 14 is pressed again. As a result, the driving device is activated, the drain plug 11 is raised, and the state indicated by the two-dot chain line in FIG. As a result, the drain port 17 is in an open state, and the hot water or water in the recess 10a flows through the drain port 17, the connecting member 18 and the holes in the inner peripheral portion 42 to the drain pipe 24, and the drain pipe. 24 is discharged to the outside.
[0032]
At that time, when a large amount of hot water or water flows into the drain pipe 24 at a time, a reverse flow occurs, and the float valve 41 is positioned at a position indicated by a one-dot chain line in FIG. As a result, the drain hole 48 is closed. In this case, since the specific gravity of the silicon rubber constituting the float valve 41 is small, the float valve 41 operates sensitively to the backflow of drainage from the bathtub 10 and can reliably prevent backflow.
[0033]
As a result, the hot water or water discharged from the bathtub 10 is gradually discharged according to the amount corresponding to the shape and the hole diameter of the drain pipe 24. In this case, even if water flows vigorously, the float valve 41 cannot further rise from the state in contact with the connecting portion 47, so that the drainage portion 45 is prevented from being detached from the holding portion main body 44. Note that when the amount of hot water or water flowing through the water distribution pipe 24 is reduced and the water level is lowered, the float valve 41 is lowered from the floating position shown by the one-dot chain line in FIG. 2 to the position shown by the solid line.
[0034]
In addition, due to the use for a predetermined period, dirt or dirt accumulates on the surface of the float valve 41, and the float valve 41 adheres to the drainage portion 45, the connecting portion 47, the inner peripheral portion 42, or the outer peripheral portion 46 and does not move. When the movement becomes dull, the drainage part 45 is removed from the holding part main body 44 side. Thereby, since the upper surface of the float valve 41 is exposed, each part of the float valve 41 and the eye plate 40 can be cleaned by extending a hand. In this case, the entire cleaning is performed while rotating the float valve 41 around the inner peripheral portion 42. Moreover, since the drainage part 45 is removed from the eye plate 40, it can be easily cleaned using a faucet or the like. When the cleaning operation is completed, the drainage unit 45 is attached to the holding unit main body 44 again. Thus, the float valve 41 operates properly at the next drainage.
[0035]
As described above, in the drainage float structure according to the present invention, a part of the upper surface of the eye plate 40 in which the drainage hole 48 is provided is constituted by the drainage part 45 provided detachably on the holding part main body 44. Therefore, when the portions of the eye plate 40 and the float valve 41 are washed, the drainage part 45 can be detached from the holding part main body 44. As a result, even if dirt such as scale adheres to the float valve 41 and the operation of the float valve 41 becomes dull or does not operate, the dirt can be easily removed. It is possible to return to the state that operates.
[0036]
FIG. 5 shows an eye plate 50 used in a drainage float structure according to another embodiment of the present invention. In the eye plate 50, a rod-like handle 52 is provided on the upper surface of the drainage part 51. About the structure of the other part of this eye plate 50, it is the same as that of the eye plate 40 mentioned above. Therefore, the same reference numerals are given to the same parts.

Further, the drainage float structure according to the present invention can be modified as appropriate within the technical scope other than both the above-described embodiments. For example, in both of the above-described embodiments, the drainage portions 45 and 51 are constituted by one member, but the drainage portion can be constituted by two pieces or a plurality of plural pieces. For example, when two drainage parts are configured, each drainage part can be formed in a substantially semicircular shape, and two connection parts can be provided between each end of the drainage part. Thereby, both drainage parts can be made removable. According to this, the drainage holes can be provided at equal intervals around the inner peripheral portion, and the drained water is not biased toward one side of the eye plate.
[0038]
Also in this case, a handle can be provided in one or both of the drainage sections, which makes it easy to attach and detach the drainage section. Moreover, also when making a drainage part into three or four pieces, it is preferable to install a connection part between each. Thereby, the connection state of the inner peripheral portion and the outer peripheral portion is stabilized. Further, it is possible to form a drain hole 48 in the connecting portion 47 as well.
[0039]
In both of the above-described embodiments, the float valve 41 is configured in a ring shape. However, the float valve 41 can be moved up and down in the holding portion main body 44 and can have various shapes as long as the drain hole 48 can be closed at the floating position. For example, it is also possible to configure a substantially U-shape or a substantially V-shape. Furthermore, other members can be used by being replaced or modified in design as long as the same effects can be obtained.
