Many elderly people) have difficulty in entering the bathtub across the side wall or peripheral wall of the bathtub at this height, and similarly straddling the bathtub to enter the washing area. In addition, when a caregiver takes care of the patient, it must be lifted and put in, so a large amount of power is required, and a caregiver without physical strength cannot assist.

[0003] Further, the depth of the bathtub is ensured by making the side wall or the peripheral wall upper surface of the bathtub slightly protrude from the floor of the washing place, and making the bottom of the bathtub body lower than the floor of the washing place. There are also things. Although this is easy to enter the bathtub, it is unsanitary because hot water or water applied to the body in the washing area enters the bathtub and contaminates the hot water in the bathtub.

Further, in Europe and the United States, a method of bubbling soap completely in a bath tub, washing the body, and then washing it off with a shower is generally used. Therefore, a shallow bath tub is used.

Further, a sliding door is provided on one side wall of the bathtub body, and after the bather enters the bathtub, the sliding door is closed, and the hot water is transferred from the adjacent hot water tank to the bathtub by operating the hot water supply device, thereby completing the bathing. After returning the bath water to the hot water tank, open the sliding door,
There has been proposed a device in which a bather in a wheelchair gets out of a bathtub (Japanese Patent Laid-Open No. 7-308357).

[0006] The bathtub disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 7-308357 has the advantage that it is possible to take a bath in a state of being in a wheelchair. However, it is necessary to separately provide facilities such as a sliding door and a hot water tank, and it becomes expensive. Since you enter the bath after getting naked in the bathtub, you have to wait until the bathtub is filled with hot water, and you have to warm up the bathroom well and have to feel cold while waiting There is. Also,
There is a problem that the person cannot go outside unless hot water is collected in the hot water storage tank even after taking a bath, which is rather inconvenient for a disabled person or an elderly person who can take a bath without using a wheelchair. In addition, it is economical in that it can be collected and used without throwing away hot water, but as hot water has been pointed out recently in 24-hour baths, etc. Doing so is not hygienic.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view of a bathroom showing an example of a bathtub of the present invention together with a washing place. In FIG. 1, the bathtub 1 includes a bathtub main body 10 and an outer wall body 7 covering a side wall 11 except for a closing plate supporting portion 15 thereof. 2 is a washing room,
3 is a hot water inlet, 4 is a drain hole, 6 is a bathroom entrance door, T
Is a handle used when a bather stands up without a bathtub. A notch 1 for reducing the height of one side wall 11 of the bathtub body 10 over one end in the longitudinal direction of the side wall.
2 are provided. The notch 12 is, in this example,
The side wall surface has an inverted trapezoidal shape, and a closing plate supporting portion 15 is provided on the periphery of the cutout portion in this example.
The outer wall body 7 is assembled so as to cover the peripheral wall thereof except for the closing plate supporting portion 15 of the bathtub body.

As described above, when the user enters and exits the bathtub 1 from the cutout portion 12, even the elderly can easily enter and exit. Even when the caregiver puts it up, if it is put up through this cutout, it is not necessary to hold it, so even a person without physical strength can be put in. In addition, since only the notch portion 12 is low, there is little possibility that hot water or the like whose body has been washed in the washing place enters the bathtub, and it is hygienic. The inventor of the present invention has previously proposed a configuration in which the cutout portion 12 is provided at the center of at least one side wall of the peripheral wall of the bathtub main body. If it is provided at the end, it can be easily immersed in hot water simply by crouching in the place immediately after entering and stretching the legs, so it is easy to operate, and when going out it is easy to get out because the waist is right next to the notch be able to.

Also, when entering the bathtub 1, as in a normal bathtub, the bath can be filled with hot water of a suitable temperature from the hot water supply port 3 in advance up to the vicinity of the bottom of the cutout portion. There is no. In addition, the entry and exit from the washing place 2 into the bathtub 1 is performed through the notch portion 12 while grasping both sides of the notch portion, so that even an elderly person or the like can easily and safely enter and exit. Furthermore, the scale from the bath that floats on the surface of the bath flows out of the notch 12 each time the bath is taken,
Since the hot water is discharged through the drain hole 4, the hot water is constantly kept clean. In addition, it is preferable that both edges of the cutout side surface 12A, the bottom surface 12B, and the like are particularly rounded for safety.

FIG. 2 shows an example in which a closing plate 14 for detachably closing the cutout portion 12 of the bathtub of FIG. 1 is provided. The closing plate 14 is an inverted trapezoidal plate-like body, and is fitted in a closing plate supporting portion 15 provided on a peripheral edge of the notch 12 and having a groove in which the closing plate 14 can be fitted. Since the width of the closing plate 14 is an inverted trapezoidal plate-like body that becomes narrower downward, it can be easily attached and detached. Further, since the gripping hole 14A is provided near the upper edge of the closing plate 14, the upper edge becomes the gripping portion 14B, and the gripping and gripping of the gripping portion 14B further facilitates attachment and detachment.

When entering the bathtub 1, first hold the holding portion 14 B of the closing plate 14 in FIG.
4 can be removed from the obstruction plate support portion 15. If the obstruction plate 14 is removed, even the elderly can easily take a bath. Further, when the closing plate 14 is closed after the legs are put in the bathtub, the surface of the molten metal becomes the holding hole 14A of the closing plate 14.
Can be ascended to the lower surface, and can be immersed in plenty of hot water. Also, in Europe and the United States, those who want to soak in generous hot water after shampooing may use this closing plate 14. At the time of bathing, it is preferable to provide an obstruction plate storage for accommodating the detached obstruction plate 14 at an appropriate position on an outer wall body described later.

If the groove 15B of the closing plate supporting portion 15 is coated with an appropriate sealing material, the sealing is performed by the watertight member, so that the outflow of hot water can be prevented. When going out of the bathtub, grasp both ends of the obstruction plate support portion 15 and stand up. Open the obstruction plate 14 when the level of the molten metal slightly lowers, and the scale is floating above the bottom surface 12B of the cutout portion. The hot water becomes clean because only the part flows out.

FIGS. 5 and 6 are views of bathtubs having different shapes of the notch portion 12, and are the same as FIGS. 1 and 2 except for the notch portion 12, the closing plate support portion 15 and the closing plate 14. FIG.
Also in this case, the width of the closing plate becomes narrower as it goes down, so that the closing plate 14 can be easily attached and detached, and the handling is the same. Further, the shape of the notch portion 12 is not limited to these, but may be any shape as long as the width is constant or narrows as it goes downward.

FIG. 3 is a view of the bathtub main body 10 of the bathtub 1 shown in FIGS. 1 and 2, and FIG.
(B) is the AA sectional view. The height H _K of the cutout bottom surface 12B from the washing floor 30 is preferably 3 cm to 10 cm. Notch bottom surface 12B
If the height H _K is less than 3 cm, the hot water or water applied to the body in the washing place 2 enters the bath tub, and contaminates the hot water in the bath tub, which is unsanitary. On the other hand, height H _K is 10cm
It is not preferable to exceed the value because it becomes difficult for the elderly and the like to straddle.

[0037] The depth of the notches bottom 12B to the bottom surface of the tub body 10 H _B is preferably set to 30cm to 50 cm. If it is less than 30 cm, the depth of the hot water for immersing the body is too shallow to warm the entire body. Also,
When getting out of the bathtub body 10, the buoyancy by the hot water works, so it is easy to straddle even if it is higher than when entering, but still 50
If it exceeds cm, it is not preferable because it becomes difficult to straddle. Further, it is preferable that the width W _k of the upper part of the notch is 40 cm to 70 cm. The reason is that if it is less than 40 cm, it is difficult to enter it, and if it is more than 70 cm, there is a large possibility that hot water or the like whose body has been washed in the washing place 2 will enter the bathtub when the obstruction plate is not used, which is unsanitary. Further, when the closing plate 14 is provided, the closing plate 14 becomes large, which is inconvenient for attaching and detaching.

Now, the flat shape of the bathtub is rectangular, the length of the inner surface of the bathtub is 60 cm × 110 cm,
When to the bottom surface of the tub body 10 depth H _B Consider the case of 35cm from B, the volume V ₁ of the up to this minimum portion 12B, a _{V 1 = 35 × 60 × 110cm} 3 = 231l human volume hot water 50l~ Assuming that it corresponds to 70 l, the rising height H _U of the bath surface when the bath is closed with the closing plate 14 closed is: H _U = (50 l to 70 l) / (60 cm × 110 cm) = 7.6 cm to 10.6 cm Therefore, the height of the hot water surface when immersed in hot water is 35c
m is obtained by adding the height of rise. Since the comfortable bathing water level is 45-60cm, the amount of hot water to be replenished is 0-
100 liters, so if you want to save water,
It is not unsatisfactory without replenishment. However, for those who want to soak in more hot water, pouring 100 liters raises the water level to 60 cm, giving a great satisfaction. When the closing plate 14 is opened while immersed in hot water, this 100 liter of hot water will flow out, but the cost is up to 12 yen at most,
There is an advantage that the descaling floating on the surface of the hot water can be removed and the hot water can be returned to clean hot water. Also, if a person who wants to save water consumption stands up in the bath tub, lowers the level of the hot water and then removes the closing plate, the amount of outflow is reduced.

In this example, the closing plate supporting portion 15 is formed such that the peripheral edge of the cutout portion 12 is formed to be thicker than the side wall 11, and a groove 15B into which the closing plate 14 can be fitted is formed in the thick wall portion 15A. is there. Since the closing plate supporting portion 15 has a large wall thickness,
Even if the groove 15B is formed, it is strong.

As shown in FIGS. 5 and 6, when the notch 12 has a smooth curved line curved downward, the height H _K of the lowest portion 12B from the floor surface 30 is 3 cm to 10 c.
m is preferable. The depth H _B to the bottom surface of the tub body 10 from the lowest portion 12B 30cm to 50c
m is preferable. Furthermore, the width of the upper part of the notch is
As in the case of the inverted trapezoid, it is preferable to set it to 40 cm to 70 cm. The reasons are the same as in the examples of FIGS.

FIG. 7 is a view showing an example in which a grip 23 is provided near the notch-side end of the upper surface of the closing plate support 15.
(A) is a partially enlarged view of a state in which the closing plate 14 is not fitted,

In FIG. 7, the grip 23 is a bowl-shaped grip having a size that can be easily gripped by the palm, and is provided with a plurality of depressions 23a on its surface such that a fingertip is applied. When taking a bath,
By gripping the grip portion 23, bathing in and out of the bath is further facilitated, and it is safe as a support when a foot slips in a washing place.

The holding portion 23 is rotatably supported by the closing plate supporting portion 15 by a rotating shaft 23b, and a slit 23c is provided on a peripheral edge thereof. When the grip 23 is rotated to align the slit 23c with the groove 15B of the obturator support, the obturator 14 becomes detachable from the groove 15C, and after the obturator 14 is inserted, the grip 14B is rotated.
It is fixed by a non-slit part without a slit. The present invention includes a case in which the grip 23 has a plurality of depressions 23a, and at least one of the depressions is provided on the periphery of the bowl-shaped grip 23 so that it also serves as a slit. The number of slits is not limited to one, but may be plural. When the rotating shaft 23b is screwed, for example, with a screw, the closing plate 14 is pressed by the grip portion 23 and pressed against the groove 15C. Therefore, it is possible to prevent hot water from leaking from a portion where the closing plate 14 contacts the groove 15. The configuration is the same as that described in the example of FIG. 3 except that the grip 23 is provided.

FIGS. 8A and 8B are explanatory views of an example in which a storage portion 16 for storing the closing plate 14 is provided when the closing plate 14 is removed. FIG. 8A is a plan view, and FIG. FIG.
