A hot air dryer 12 is detachably installed at the upper end of the bathtub 1. The user can put his head out and put his whole body in a kotatsu to warm his whole body.

When the user removes the defecation lid 7, there is a plan to provide the defecation plate 7 on the seating seat 6 so as to be slidable so that the defecation plate 7 can be pulled out. Even in that case, the user needs to raise his hips a little and reduce the friction when pulling out. Assuming that the user cannot raise his / her waist, a mechanism is provided in which the defecation lid 7 is brought into contact with the protruding inclined plate 25 at the bottom of the bathtub 1 and automatically set aside.

FIG. 13 is a structural diagram in which the defecation lid 7 is supported by the seat portion 6b of the seat seat 6. The defecation lid 7 is provided so as to be sandwiched between the left and right seat portions 6b. Then, it is supported by a pin 32 provided on the seat portion 6b. As an example, the pins 32 can be provided at two locations on the left side and two locations on the right side, for a total of four locations, on the side surface of the defecation hole 9 of the seat portion 6b. The pin 32 is attached to the spring foot 30 via the L-shaped metal fitting.

FIG. 14 is an explanatory diagram when the pin 32 supporting the defecation lid 7 comes off. When the multifunctional bed 100 is set to the bathing mode 100d, the backrest portion 6a of the seating seat 6 stands up by the telescopic arm 18 and the auxiliary telescopic arm 27, is pushed forward and tilts, and a step is set inside the bathtub 1. Form and sink halfway. In that case, the seat portion 6b and the defecation lid 7 abut on the protruding inclined plate 25 at the bottom of the bathtub 1. Then, the spring foot 30 is pushed upward, and the pin 32 comes off from the defecation lid 7. It is assumed that the spring foot 30 does not move downward due to the lock mechanism 33. Therefore, the pin 32 does not support the defecation lid 7.

FIG. 15 is an explanatory diagram in which the defecation lid 7 is placed at the bottom of the bathtub 1. Following FIG. 14, an instruction is given to switch from the bathing mode 100d to the chair mode 100b. In that case, since the pin 32 does not support the defecation lid 7, the seating seat 6 is raised and the defecation lid 7 is set aside at the bottom of the bathtub 1. When the bathing mode 100d is set again, the seating seat 6 is lowered, and the spring legs 30 of the seat portion 6b come into contact with the protruding inclined plate 25. In that case, since the lock mechanism 33 is released, the spring foot 30 extends, the pin 32 protrudes, and the defecation plate 7 is supported. Therefore, when the chair mode 100b is returned, the defecation lid 7 also rises together with the seat portion 6b. A convex portion (not shown) is provided on the bottom of the defecation lid 7, a concave portion (not shown) is provided on the protruding inclined plate 25, and the defecation plate 7 is mistakenly placed back and forth by engaging with each other. Prevents it from moving in the left-right direction. If the defecation lid 7 is accidentally moved, the defecation plate 7 cannot enter the defecation hole 9 of the seat portion 6b when the seating seat 6 is lowered.

However, electromagnets are provided on both the protruding inclined plate 25 side of the bathtub 1 and the seat portion 6b side of the seating seat 6. It is also possible to control whether the permanent magnet provided on the defecation lid 7 is attracted to the side of the seat portion 6b or the side of the protruding inclined plate 25 by controlling the on / off of the electromagnet. According to this, the instruction from the operation panel is set to the bathing mode to take a bath, but it is divided into the operation of not leaving the defecation lid 7 and the operation of leaving the defecation lid 7 for defecation instead of taking a bath. Can be done.

The present invention is suitable as a multifunctional bed with a bath / toilet for a person who can operate by himself / herself without much help of a caregiver.
