After the drainage is completed, the piston 58a of the drain plug opening / closing cylinder 58 moves downward, the drain plug 53 is inserted into the recess 55, and the fully automatic operation ends.

  Here, when washing away is insufficient, or when washing the bather's M hair, it is performed by the hand shower equipment 65 provided. At this time, the arm member 29 arranged on the side of the bather M can be rotated upward to open the hood 14.

  Finally, the cylinder 40 provided symmetrically below the bottom surface of the bathtub main body 28 is driven while being synchronized, and the pair of bottom seal members 33 are moved outwardly away from each other to support the support rod 11 of the wheelchair 2 from both sides. The bottom seal member 33 sandwiching is opened. Further, the arm member 29 arranged on the side of the bather M is rotated upward to open the hood 14, and a lock provided between the other side portion of the door 4 and the other end portion of the front end of the bathtub main body 28. The mechanism 78 is released and the door 4 is opened. Then, the wheelchair 2 on which the bather M is placed is moved to the front of the bathtub 3 to take out the bather M from the bathing apparatus 1 and complete the bathing. In addition, the hot water supply means 5, the shower means 6, the tank drain means 7, the pipe drain means 12, etc. can be performed individually.

  According to the bathing apparatus 1 having the above-described configuration, the in-pipe draining means 12 for draining hot water remaining in the first shower hot water supply pipe 13 is provided, so that the first shower before the shower means 6 is used. The cooled water remaining in the hot water supply pipe 13 is discharged, and hot water having an appropriate temperature is supplied to the injection nozzle 48 from the beginning. Accordingly, hot water having an appropriate temperature can be jetted from the jet nozzle 48 from the beginning, and the bather M can be showered at an appropriate temperature.

  The pipe drain means 12 is connected to the first shower hot water pipe 13 via the valve body 19 provided in the lowest portion 13a of the first shower hot water pipe 13 and directed downward. Therefore, the valve body 19 is switched so that the in-pipe drain pipe 20 communicates with the first shower hot-water pipe 13, thereby remaining in the first shower hot-water pipe 13. The hot water that has flowed down into the pipe drain pipe 20 is drained. At this time, the hot water remaining in the first shower hot water supply pipe 13 flows down into the pipe drain pipe 20 without using a pumping equipment such as a pump. Costs can be reduced.

  In addition, since the limit mechanism 21 is provided on the rotating shaft 29a of the arm member 29, the shower pump 47 should be used when the arm member 29 is raised and the hood 14 is opened during the operation of the bathing apparatus 1. Since the shower is stopped and the spraying of the shower is stopped, the hot water can be prevented from splashing outside the bathtub 3.

  As mentioned above, although embodiment of the bathing apparatus which concerns on this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, in the above-described embodiment, the bathing apparatus 1 for bathing the bather M while sitting on the wheelchair 2 has been described. However, the present invention provides, for example, bathing for bathing the bather on the stretcher together with the stretcher. It may be a device or other bathing device for care.

In the above-described embodiment, the bath apparatus 1 that can perform the lower body bath and the shower bath at the same time has been described. However, the present invention may be a bath apparatus 1 that performs only the shower bath.
Moreover, in above-described embodiment, the pipe | tube drainage means 12 which discharges | emits the residual water in the hot water supply pipe (1st shower hot water supply pipe | tube 13) of the shower means 6 which injects a shower from the inner wall face of the bathtub 3 is demonstrated. However, the present invention may be a discharge means for discharging water remaining in a hot water supply pipe of a hand shower facility, for example.

  In the embodiment described above, the residual water in the first shower hot water supply pipe 13 is discharged by the in-pipe discharge means 12 before the shower means 6 is used, but the present invention uses the shower means 6. The residual water in the first shower hot water supply pipe 13 may be discharged immediately by the pipe discharge means 12 later.

  Further, in the above embodiment, the in-pipe discharge means 12 is performed by a natural drainage type drainage method, but the present invention may forcibly discharge the residual water in the hot water supply pipe by a pump drainage type.

  Moreover, in above-mentioned embodiment, although the front-end part of the bathtub 3 is the single-opening type door 4, and the front-end part of the bathtub 3 is opened and closed, this invention is a side part and rear-end part of the bathtub 3. A door that opens and closes may be formed, may be double-opening type or pull-out type, and the opening and closing part and the opening and closing method are not limited and can be appropriately changed.
