The pipe joint 53 itself and the connecting portion between the pipe joint 53 and the pipe 52 are positioned to overlap the space inside the water receiving tray 40 through the opening 41 .

Next, the work at the installation site of the bathroom unit 1 according to the embodiment will be described.

For example, the installation of the bathtub 10, the washing space floor 20, the water receiving tray 40, etc. is carried out by a bathroom installation company, and the installation of the piping 52 connected to the water heater and the circulation adapter 51 is carried out by a hot water supply related company (water heater manufacturer, gas company, electrical contractors, etc.).

Therefore, after the bathroom installation company installs the bathtub 10 and the washing space floor 20 in the bathroom installation space, the water receiving tray 40 may be installed before the circulation adapter 51 is attached to the bathtub 10 .

The side walls 44 of the water receiving tray 40 are fixed to the rising surface 15 of the bathtub 10 by, for example, adhesive. At this time, the through holes 17 formed in the rising surface 15 of the bathtub 10 are positioned within the through holes 42 of the water receiving tray 40 . Further, as shown in FIG. 3, the washing area side portion 46 of the water receiving tray 40 is placed on the upper surface of the bank portion 22 of the washing area floor 20 and fixed to the bank portion 22 by screwing, for example.

Thereafter, a hot water supplier attaches the circulation adapter 51 to the through hole 17 formed in the rising surface 15 of the bathtub 10 . At this time, the water receiving tray 40 has already been installed. A worker grasps the circulation adapter 51 by hand from an opening 41 protruding toward the washing area from the side surface 11 of the bathtub 10 and inserts it into the water receiving tray 40, thereby exposing the bathtub 10 exposed in the water receiving tray 40. A circulation adapter 51 can be attached to the through hole 17 of the. When inserted into the opening 41 , at least a portion of the pipe 52 closer to the circulation adapter 51 than the pipe joint 53 is connected to the circulation adapter 51 .

After attaching the circulation adapter 51 to the bathtub 10 , a pipe 52 extending along the side surface 11 of the bathtub 10 is connected to the circulation adapter 51 via a pipe joint 53 . Alternatively, the flexible pipe 52 is connected to the circulation adapter 51 without the pipe joint 53, and the circulation adapter 51 with the pipe 52 connected is inserted into the water receiving tray 40 from the opening 41, You may attach to the through-hole 17 of the bathtub 10. FIG. Since the pipe 52 is flexible, it can be bent along the side surface 11 of the bathtub 10 from the connection with the circulation adapter 51 . Alternatively, only the circulation adapter 51 may be attached to the through hole 17 of the bathtub 10 first, and then the piping 52 may be grasped by hand and inserted into the water receiving tray 40 through the opening 41 to be connected to the circulation adapter 51 .

Before or after attaching the circulation adapter 51 to the bathtub 10 , one end of the drain hose 61 is connected to the tray drain port 43 of the water receiving tray 40 and the other end is connected to the apron guide 62 . After that, the apron 31 is attached as shown in FIG.

Even if water leakage occurs during use of the bathroom unit 1 due to an error during construction at the connection point between the bathtub 10 and the circulation adapter 51, the leakage water can be received by the water receiving tray 40, and the outside (bathtub 10 can prevent water leakage to the lower side of the

Water can be stored in the water receiving tray 40 up to a water level higher than the position (vertical position) of the drain hole 63 formed in the apron guide 62 . The drain hole 63 is open to the atmosphere toward the washing place side, and when the water in the water receiving tray 40 accumulates to a water level higher than the position of the drain hole 63, the water in the water receiving tray 40 is drained through the drain hose 61. It flows toward the hole 63 and is drained from the drainage hole 63 toward the floor surface of the floor 20 of the washing place.

The leaked water accumulated in the water receiving tray 40 is drained on the floor surface of the washing place floor 20 instead of the trap under the drain port 23 of the washing place floor 20 (which is also the bathtub water drain destination). A person can recognize the abnormality (water leakage at the connection point between the bathtub 10 and the circulation adapter 51) and take appropriate measures before water leakage outside the machine. In addition, backflow of waste water from the trap side to the water receiving tray 40 can also be prevented. Also, when connecting the other end of the drain hose 61 to the trap, it is possible to avoid the risk of water leakage to the outside of the machine due to the worker forgetting to connect the trap during construction at the site.

According to the embodiment described above, when the circulation adapter 51 is attached to the through hole 17 formed below the seating surface 16 of the step 14 provided on the short side of the bathtub 10 after the water receiving tray 40 is attached. 3, when the water receiving tray 40 is installed above the rising surface 15 in order to secure the drainage gradient toward the washing place floor 20 in the limited space below the seating surface 16, the upper part of the water receiving tray 40 and the seating surface Even if the distance to 16 is close, the site worker can easily attach the circulation adapter 51 to the through hole 17 of the bathtub 10 through the opening 41 projecting toward the washing area from the seating surface 16 and the side surface 11 of the bathtub 10. becomes.

In addition, since the opening 41 protrudes toward the washing place from the end 22a of the bank 22 of the washing place floor 20 on the side of the bathtub 10, a larger area of the opening 41 protruding from the side surface 11 of the bathtub 10 is ensured. can. Therefore, workability is improved when the circulation adapter 51 is inserted from the opening 41 and attached to the bathtub 10 .

In addition, since the water receiving tray 40 is made of an elastic material, for example, the upper wall portion 45 (shown in FIGS. 3 and 6) of the side wall of the water receiving tray 40 opposite to the rising surface 15 of the bathtub 10 can be elastically deformed. can be done. The upper end of the upper wall portion 45 forms part of the edge of the opening 41 .

For example, by pressing the upper wall portion 45 with the operator's arm and elastically deforming it so that it falls into the water receiving tray 40, the right side of the water receiving tray 40 in FIG. A large space can be secured between the seat surface 16 and the seat surface 16 on the opposite side). Even if the opening 41 of the water receiving tray 40 does not protrude from the space below the seating surface 16 to the right in FIG. Workability when inserting and attaching the circulation adapter 51 to the bathtub 10 can be ensured. That is, the water receiving tray 40 can be made compact while maintaining workability when attaching the circulation adapter 51 to the bathtub 10 .

By making the water receiving tray 40 compact, the volume of water stored in the water receiving tray 40 can be reduced. As a result, the water storage time until reaching the water level at which drainage starts in the water receiving tray 40 can be shortened, and the water receiving tray 40 is deformed by the weight of the accumulated water and leaks out of the machine (to the lower side of the bathtub). can be suppressed.

A portion 46 of the water receiving tray 40 on the side of the washing area is placed on the bank portion 22 of the floor 20 of the washing area. That is, the portion 46 of the water receiving tray 40 on the washing area side is supported by the bank portion 22 of the washing area floor 20 . Therefore, even if a material that can be elastically deformed is used for the water receiving tray 40, deformation of the water receiving tray 40 due to the weight of water can be suppressed when water is stored in the water receiving tray 40.例文帳に追加Therefore, it is possible to prevent the water in the water receiving tray 40 from leaking to the outside (downward side of the bathtub) due to deformation due to the weight of the water.

It should be noted that the entire water receiving tray 40 need not be elastically deformable. For example, if at least the upper wall portion 45 of the side wall on the opposite side of the rising surface 15 of the bathtub 10 is elastically deformable, as described above. By pressing the upper wall portion 45 with the operator's arm, the space for inserting the operator's arm into the water receiving tray 40 can be expanded.

The pipe 52 may be connected to the circulation adapter 51 without using the pipe joint 53 and bent along the side surface 11 of the bathtub 10, as described above. However, if the pipe joint 53 is used, the workability is excellent without considering the allowable bending radius of the pipe 52 when extending the pipe 52 along the side surface 11 of the bathtub 10 from the connection portion with the circulation adapter 51 . In addition, as shown in FIG. 8, since the opening 41 of the water receiving tray 40 extends below the pipe joint 53, the water receiving tray 40 can also receive water leakage from the joint between the pipe joint 53 and the pipe 52. becomes possible.

FIG. 3 shows an example in which the tray drain port 43 is formed on the lower side of the water receiving tray 40, but the tray drain port 43 may be formed on the upper side of the water receiving tray 40. FIG. However, when the tray drain port 43 is formed on the lower side of the water receiving tray 40, out of the leaked water stored in the water receiving tray 40, drainage starts from the old water at the bottom where dirt etc. have settled. Therefore, the stored leaked water can be smoothly replaced, and such old water can be prevented from remaining in the water receiving tray 40 forever.

As shown in FIG. 6, the upper end surface of the washing area side portion 46 of the water receiving tray 40 has a notch portion 47 that is stepped toward the washing area side from the upper end surface of the other portion. Therefore, when the amount of water leakage from the connection point between the bathtub 10 and the circulation adapter 51 exceeds the amount of drainage from the tray drain port 43, the water exceeding the full water level does not leak outside the machine, and the cutout portion It is possible to drain water from 47 to the washing area floor 20.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to them, and various modifications are possible based on the technical idea of the present invention.
