[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a bath according to the present invention. As shown in the sectional views of FIGS. 2 and 4, the bathtub 1 shown in the drawing is a ring-shaped tube of a required book (for example, six tubes) that can individually take in and out air. The holding frame 10 is constructed by vertically stacking 20, 20, ... And bonding them to each other.

Each of the tubes 20 is provided with a plug 22 to which an inflator is connected. When the tube 22 is filled with air, the tube 22 is inflated. The thickness in the depth direction can be adjusted. It should be noted that FIGS. 1 to 4 show a state in which air is introduced into all six tubes 20 at about 2/3 of the maximum injection amount. Each tube 20 becomes flatter as the injection amount decreases.

Then, a bath tub 30 made of a flexible sheet material that does not allow hot and cold water to pass through the holding skeleton 10 is developed into a bottomed cylindrical shape so as to cover the inner and outer circumferences of the holding skeleton 10 composed of the six tubes 20. It is kept in a state.

That is, the bath tub 30 of the flexible sheet material is integrally connected to the outer peripheral portion 31 that covers the outer periphery of the holding skeleton 10 and the outer peripheral portion 31, and covers the inner periphery of the holding skeleton 10. It is composed of an inner peripheral portion 32 having a bottomed cylindrical shape, and the lower end of the outer peripheral portion is connected to a bottom sheet 35 made of a circular heat insulating mat laid on the ground by a chuck 36 or the like. The bottom surface 32 a of the inner peripheral portion 32 is placed on the bottom surface sheet 35.

Hot water inlet / outlet ports 41, 42 made up of a pair of short pipes with flanges are provided above and below the bottom of the holding skeleton 10 and the bath tub 30 so as to laterally pass through them. . Here, in the present embodiment, as can be clearly understood with reference to FIG. 3, the corresponding two tubes 20 and 20 (the second and fourth stages from the bottom) of the tubes 20 are It is not a complete ring, but a notched ring shape with a part notched in the circumferential direction. As can be seen from FIG. 4, the hot and cold water inlet / outlet port is formed so as to pass through the notches 20a, 20a. 41 and 42 are arranged sideways, and corresponding holes of the inner peripheral portion 32 and the outer peripheral portion 31 of the bath tub 30 made of the flexible sheet are installed near both ends of the hot and cold water inlets and outlets 41 and 42. Appropriate fasteners 37, 37 are used to seal and fix them like water.

Further, the hot and cold water inlets and outlets 51 and 42 of the boiler 50 are connected to the pair of hot and cold water inlets and outlets 41 and 42 via pipes 43 and 44 by fasteners 47 and 47 in a honey comb manner.

The boiler 50 uses gas or petroleum as a fuel, hot water stored in the bath tub 30 is introduced from the hot water inlet / outlet port 51 through the hot water inlet / outlet port 41 and the pipe 43, and the hot water introduced is introduced. The inside of the bath tub 30 is heated and heated, and is returned from the hot and cold water inlet / outlet 52 through the pipe 44 and the hot and cold water inlet / outlet 42 into the bath tub 30 for circulation.

As shown in FIG. 1, a drain hose 39 made of the same material is connected near the bottom of the inner peripheral portion 32 of the bath tub 30 made of the flexible sheet. When the drain hose 39 is not used (when the drain is not drained), the drain hose 39 is hooked on the hook 33 attached to the upper portion of the outer peripheral portion 31 of the bath tub 30, and when drained, it is shown by a virtual line in FIG. As described above, the hot and cold water accumulated in the bath tub 30 is discharged so as to crawl on the ground.

In the bathtub 1 having such a configuration, when the bathtub 1 is not used (during storage / transportation, etc.), the holding frame 10 and the bath tub 30 are separated from each other, and the tube 20 is separated. , 20, ... are deflated and flattened. As a result, the space occupied by the bathtub 1 becomes extremely small, which facilitates storage and transportation.

Then, when the bathtub 1 is used, the tubes 20, 20, ... Constituting the holding body 10 are appropriately filled with air and placed on the bottom sheet 35, and thereafter, the bath tub 30 mentioned above is placed. The inner peripheral portion 32 and the outer peripheral portion 31 are set as described above, and the hot and cold water inlets and outlets 51 and 52 of the boiler 50 are connected to the hot and cold water inlets and outlets 41 and 42 through the pipes 43 and 44 with fasteners 47 and 47. Connect to.

Next, water is put into the bath tub 30 and is circulated while heating the temperature in the boiler 50 as described above.

Here, in the bathtub 1 of the present embodiment, as described above, when assembling it, the amount of air to be put into the tubes 20, 20, ... Is adjusted to adjust the thickness in the height direction thereof. Adjust. In this case, for example, as shown in FIG. 4, when the air is put into the six tubes 20 about 2/3 of the maximum injection amount, the height of the bathtub 1 becomes relatively high (height H). , Enough water can be put in the bath tub 30. On the other hand, as shown in FIG. 5, the height of the bathtub is relatively low (height H ′) when only about 1/2 of the maximum injection amount is put into the six tubes 20. .

As described above, the height of the bathtub can be arbitrarily and easily changed by adjusting the amount of air to be put into each tube 20, so that it is easy for children and the elderly to come in and out of the bathtub. It is convenient to reduce the height of the bathtub.

Further, the holding frame 10 is made up of required tubes 20, 20, and so on, and a bath tub 30 made of a flexible sheet material is held on the inner peripheral side thereof in a state of being expanded into a bottomed cylindrical shape. Therefore, the holding skeleton 10 including the tube 20 works effectively as a heat insulating material with the outside, and therefore, the hot and cold water retaining property becomes better than the conventional one, and the fuel cost of the boiler 50 can be reduced.

Further, since the holding frame 10 including the ring-shaped tubes 20, 20, ... Adhering to each other does not easily lose its shape and requires a large installation area, the installation stability is higher than that of the conventional one. And is remarkably excellent.

In addition to the above, a pair of hot and cold water inlets and outlets 41 and 42 are provided above and below the bottom of the holding skeleton 10 and the bath tub 30 so as to laterally pass through the side of the holding skeleton 10 and the bath tub 30. Since the hot and cold water inlets and outlets 41 and 42 are connected to the hot and cold water inlets and outlets 51 and 52 of the boiler 50, it is possible to easily and easily heat and raise the temperature while circulating the hot and cold water rationally.
