Bathing using bathtub 1 ends.

  As described above, in the nursing bathtub 1, the U-shaped lower end 301 of the door portion 3 comes into contact with the upper surface 211 of the bottom surface portion 21 of the main body portion 2, so that the door portion 3 is caused by its own weight. The door portion 3 can be attached to the main body portion 2 while the lower end 301 thereof is in strong contact with the bottom surface portion 21. As a result, it is possible to improve the water tightness between the door portion 3 and the main body portion 2 in the vicinity of the bottom surface portion 21 to which a high water pressure is applied during bathing. Moreover, the strength of the door portion 3 can be improved by providing the second side surface portions 32 at both side ends of the front surface portion 31 as compared with the case where the door portion is configured by only the flat front surface portion.

  In the nursing tub 1, the door 3 and the main body 2 are provided with a convex portion 34 and a concave portion 25 that are formed continuously along the boundary between the door portion 3 and the main body portion 2 and fit to each other. A sealing material 26 having elasticity is provided inside. When the door part 3 is closed, the sealing material 26 is in close contact with the convex part 34 and the concave part 25 at the boundary between the door part 3 and the main body part 2. The sex can be further improved.

  Moreover, the lower end 301 of the door part 3 is attached to the main body part 2 via a hinge 33, and when the door part 3 is opened, it becomes a slope for carrying in and out of a wheelchair, thereby easily opening and closing the door part 3. In addition, it is possible to easily enter and exit the nursing tub 1 using a wheelchair.

  As described above, since the door portion 3 has high strength by including the front surface portion 31 and the pair of second side surface portions 32, the wheelchair is reliably supported when the front surface portion 31 is used as a slope. can do. Moreover, since a pair of 2nd side part 32 plays the role of what is called a guard, it can prevent a wheelchair falling from the front part 31 which is a slope, and can enter / exit in the main-body part 2 safely.

  In the care bathtub 1, the body part 2 and the door part 3 are made of wood, so that the bather can be relaxed due to the touch, the scent and the like, and the feeling of use can be improved. In addition, bathtubs of various sizes can be easily manufactured according to the bather's physique and the like. In general, in a wooden bathtub, high strength is required at the boundary between the front surface portion and the rear surface portion and the side surface portion. In the care bathtub 1, as described above, since the boundary between the front surface portion 31 and the second side surface portion 32 is fixed in the door portion 3, the door portion is configured by only the flat front surface portion. Compared with the case where a part is attached to a side part, the intensity | strength of the boundary of the front part 31 and the 2nd side part 32 can be improved. Therefore, it can be said that the structure of the care bathtub 1 is a structure particularly suitable for a wooden bathtub.
