[0009] First, embodiments of the present disclosure will be listed and described. Any combination of the following embodiments without causing any contradiction is also included in the embodiments for carrying out the invention. [1] The bathtub disclosed herein comprises a sheet-made bathtub body that is used to store hot water in a suspended state, and a mounting part that is attached to the bathtub body and has a water discharge device with a water discharge part. This bathtub can store hot water in the bathtub body by discharging hot water into the bathtub body from the water discharge device attached to the mounting part. In this case, because this bathtub can discharge hot water from a location close to the bathtub body, it is possible to prevent the temperature of the water stored in the bathtub body from decreasing. [2] In the bathtub described in [1] above, the water outlet is positioned above the upper edge of the bathtub body when it is suspended. This bathtub can discharge hot water from the water outlet positioned above the upper edge of the bathtub body. This makes it easier for hot water to hit the shoulders and neck of a bather inside the bathtub body, giving the bather a comfortable bathing experience. [3] In the bathtub described in [1] above, the mounting part can house the water discharger, and has an opening through which hot and cold water discharged from the water discharger part passes when the water discharger is housed in the mounting part. With the water discharger housed in the mounting part, the hot and cold water discharged from the water discharger part through the opening can be stored in the bathtub body. [4] In the bathtub described in [3] above, the opening is formed at the top of the bathtub body when it is suspended. This bathtub can discharge hot and cold water from the opening formed at the top of the bathtub body. Therefore, this bathtub can prevent the temperature of the hot water stored in the bathtub body from decreasing. [5] In the bathtub described in any one of [1] to [4] above, the water discharge device is a hand shower. In this bathtub, the hand shower used for washing the body can be used as a water discharge device to collect hot and cold water in the bathtub body. [6] The bathroom of the present disclosure is equipped with a hanging part for hanging the bathtub described in any one of [1] to [5] above. This bathroom can be used by hanging the bathtub on the hanging part, or by removing the bathtub from the hanging part and using it as a shower room, etc.

[0010] <Embodiment 1> Embodiments 1 and 2 embodying the bathtub and bathroom of the present disclosure will be described with reference to the drawings. The bathtub 10 of embodiment 1 is placed in a bathroom 50, as shown in FIG. 1. The bathroom 50 includes walls W1, W2, and W3, a ceiling C, and a floor F. The bathroom 50 also includes a wall (not shown) facing wall W3. This wall has an entrance with a door for accessing an adjacent changing room (not shown). The upper surface of the floor F is generally flat. A slight water gradient is provided on the floor F to allow hot and cold water to flow toward a drain (not shown).

[0011] Bathroom 50 is equipped with a shower device 60. Shower device 60 is arranged on wall W1. Shower device 60 is arranged on wall W1 near wall W3. Shower device 60 has a faucet 61, an overhead shower 63, and a hand shower 65. Shower device 60 is connected to a water supply pipe and a hot water supply pipe (not shown) inside wall W1. Faucet 61 is a mixer faucet. Faucet 61 can adjust the amount of water, adjust the temperature by mixing hot and cold water, stop the water discharge, and switch the flow path. Faucet 61 has a discharge pipe 61A. The hot water or cold water discharged from shower device 60 arranged in bathroom 50 is called hot and cold water regardless of the temperature, mixing ratio, etc.

[0012] The overhead shower 63 is located above the faucet 61. The overhead shower 63 is connected to the faucet 61 via piping 67. The piping 67 extends vertically upward from the faucet 61 along the surface of the wall W1 and bends at its upper end in a direction away from the wall W1. The overhead shower 63 is located at the tip of this piping 67. The hand shower 65 is connected to the faucet 61 via a hose 69. The hand shower 65 can be moved freely within the length of the hose 69. The hand shower 65 is cylindrical. The hand shower 65 is located on part of its outer periphery and has a spray plate 66 with multiple shower holes formed in it. The spray plate 66 corresponds to the water discharge section. The shower device 60 can discharge hot or cold water by selecting one of the water discharge pipe 61A of the faucet 61, the overhead shower 63, or the hand shower 65.

[0013] The bathroom 50 can be fitted with a bathtub 10 (described later) in a position close to the wall W3 in a removable manner. When the bathtub 10 is fitted to the bathroom 50, a space is formed on the opposite side of the wall W3 where the bather can wash their body. The bathroom 50 can be used with the bathtub 10 removed. By removing the bathtub 10, the bathroom 50 can be used as a shower room or the like.

[0014] Two hanging members 70 are provided on each of the opposing walls W1 and W2. The hanging members 70 correspond to the hanging portions. Each hanging member 70 is shaped like a J-shaped hook in a side view, opening upward, and is fixed to each of the walls W1 and W2. The two hanging members 70 provided on the wall W1 side are located below the faucet 61 and spaced apart horizontally. The distance between the two hanging members 70 fixed to the wall W1 is slightly wider than the length of the upper ends of the third and fourth side wall portions 23 and 24 of the bathtub body 20, which will be described later. The two hanging members 70 fixed to the wall W2 side are located opposite the two hanging members 70 fixed to the wall W1, and are fixed at the same height and at the same distance as the two hanging members 70 on the wall W1 side.

[0015] The bathtub 10 is hung in the bathroom 50 by hooking four loop portions 41 (described later) onto the hook-shaped portions of four hanging members 70 provided on the walls W1 and W2. The bathtub 10 is positioned close to the wall W3. The bathtub 10 can be attached to and detached from the bathroom 50.

[0016] As shown in Figures 1 and 2, the bathtub 10 comprises a bathtub main body 20, an attachment portion 30, and two ropes 40. The bathtub main body 20 is formed by cutting and welding a single sheet. The sheet has a two-layer structure in which polyester fabric and polyurethane film are laminated. The polyester fabric has excellent heat resistance and chemical resistance. The polyester fabric is a plain weave with high tensile strength. The polyurethane film is impermeable and has excellent water resistance. The sheet is flexible. The sheet has little stretchability. The bathtub main body 20 is formed so that the polyester fabric is on the outside and the polyurethane film is on the inside.

[0017] The bathtub body 20 is used by filling it with hot water while hanging by hooking the loop portions 41 onto each of the hanging members 70. The bathtub body 20 is rectangular in plan view when filled with hot water (hereinafter referred to as plan view).

[0018] The bathtub body 20 has four side walls 21, 22, 23, and 24. The first side wall 21 and the second side wall 22 extend downward from a pair of opposing long sides in a plan view. The third side wall 23 and the fourth side wall 24 extend downward from a pair of opposing short sides in a plan view. Both end edges of the third side wall 23 and the fourth side wall 24 are continuous with both end edges of the first side wall 21 and the second side wall 22.

[0019] The bathtub body 20 has folded portions 25 formed into a cylindrical shape by folding the upper edge portions of the first side wall portion 21 and the second side wall portion 22 outward. Each folded portion 25 is formed over the entire upper edge portions of the first side wall portion 21 and the second side wall portion 22. Both ends of each folded portion 25 are open.

[0020] The mounting portion 30 forms the upper edge of the fourth side wall portion 24. The mounting portion 30 is formed in a cylindrical shape by extending the sheet that forms the bathtub main body 20 from the upper edge of the fourth side wall portion 24. The mounting portion 30 is open at both ends, allowing the hand shower 65 to be inserted and stored. The hand shower 65 corresponds to a water discharge device. The mounting portion 30 has an opening 30A formed on the side of the central portion that faces into the bathtub main body 20. Hot and cold water discharged from the spray plate 66 passes through the opening 30A when the hand shower 65 is stored in the mounting portion 30.

[0021] Two ropes 40 are inserted into the folded portions 25 formed on the first side wall portion 21 and the second side wall portion 22. Each rope 40 reinforces the bathtub body 20 by being inserted into each folded portion 25. Both ends of each rope 40 extend outward from both ends of each folded portion 25 of the bathtub body 20. Both ends of each rope 40 extending outward from both end openings of each folded portion 25 of the bathtub body 20 are sewn near the opening of the folded portion 25 and to the tip to form a loop portion 41. Each rope 40 is sewn to the bathtub body 20 inside both end openings of each folded portion 25 of the bathtub body 20.

[0022] The bathtub 10 is suspended in the bathroom 50 by hooking the loops 41 formed at both ends of each rope 40 onto four hanging members 70 fixed to the walls W1 and W2. The bathtub 10 is detachable from the bathroom 50. The bathtub 10 deforms when filled with water while suspended by hooking the loops 41 onto the hanging members 70. When filled with water, the central underside of the bathtub body 20 contacts the floor F. Because the bathtub body 20 is formed from a sheet with little elasticity, the bathtub 10 maintains its boat-like shape to some extent when filled with water. Because the floor F supports most of the load when filled with water, the reinforcing structure of the walls W1 and W2 can be simplified compared to when the bathtub 10 is supported solely by the walls W1 and W2. The bathtub 10 can be freely reshaped, such as folded, unfolded, or filled with water.

[0023] <Embodiment 2> As shown in Figures 3 and 4, the bathtub 110 of embodiment 2 differs from embodiment 1 in the shape of the hand shower 165 and the mounting part 130. The other configurations are the same as embodiment 1. The same components as embodiment 1 are given the same reference numerals and detailed explanations will be omitted.

[0024] Hand shower 165 of embodiment 2 has a disk-shaped head portion 165B at the tip of handle portion 165A that is approximately rectangular prism-shaped. Head portion 165B has a circular spray plate 166 on one side. Spray plate 166 has multiple shower holes formed in it. Spray plate 166 corresponds to the water discharge portion.

[0025] The mounting portion 130 is provided on the upper part of the outer surface of the fourth side wall 24. The mounting portion 130 is formed by attaching a mounting portion main body 131 to the outer surface of the fourth side wall 24. The mounting portion main body 131 is rectangular in shape, elongated in the vertical direction, and is formed from the same sheet as the bathtub body 20. The mounting portion main body 131 is attached to the outer surface of the fourth side wall 24 with a pair of long sides extending parallel to each other in the vertical direction and spaced apart. When the mounting portion main body 131 is attached to the outer surface of the fourth side wall 24, the center between the pair of long sides forms a space between the outer surface of the fourth side wall 24 and the center portion between the pair of long sides to accommodate the handle 165A of the hand shower 165. One long side of the mounting portion main body 131 is welded to the fourth side wall 24. The other long side of the mounting portion main body 131 is detachably attached to the outer surface of the fourth side wall 24 by a hook-and-loop fastener.

[0026] When a bather or the like attaches the hand shower 165 to the fourth side wall 24, the bather or the like first peels the other long side of the attachment body 131, which is detachably attached by hook-and-loop fasteners, from the outer surface of the fourth side wall 24. The bather or the like then positions the head 165B of the hand shower 165 above the upper edge of the fourth side wall 24, with the sprinkler plate 166 facing into the bathtub body 20. The bather or the like then attaches the other long side of the attachment body 131, which is detachably attached by hook-and-loop fasteners, to the outer surface of the fourth side wall 24 so that the grip 165A of the hand shower 165 is stored in the attachment part 130. In this way, the hand shower 165 is attached to the attachment part 130, and the sprinkler plate 166 of the head 165B of the hand shower 165 is positioned above the upper edge of the fourth side wall 24, facing into the bathtub body 20.

[0027] As explained above, the bathtubs 10, 110 of the first and second embodiments comprise a sheet-made bathtub body 20 that is used in a suspended state to store hot and cold water, and a mounting portion 30, 130 that is provided on the fourth side wall portion 24 of the bathtub body 20 and that mounts a hand shower 65, 165 with a spray plate 66, 166. The bathtub 10, 110 can store hot and cold water in the bathtub body 20 by discharging hot and cold water from the hand shower 65, 165 attached to the mounting portion 30, 130 into the bathtub body 20. In this case, because the bathtub 10, 110 can discharge hot and cold water from a location close to the bathtub body 20, it is possible to prevent the temperature of the water stored in the bathtub body 20 from dropping.

[0028] In the bathtub 110 of embodiment 2, the sprinkler plate 166 is positioned above the upper edge of the fourth side wall 24 of the bathtub main body 20 when it is suspended. This bathtub 110 can spray hot water from the sprinkler plate 166 of the hand shower 165, which is positioned above the upper edge of the fourth side wall 24 of the bathtub main body 20. Therefore, this bathtub 110 makes it easy to spray hot water onto the shoulders and neck of a bather inside the bathtub main body 20, giving the bather a comfortable bathing experience.

[0029] In bathtub 10 of embodiment 1, attachment part 30 can store hand shower 65, and is formed with opening 30A through which hot and cold water sprayed from spray plate 66 passes when hand shower 65 is stored. With hand shower 65 stored in attachment part 30, bathtub 10 allows hot and cold water sprayed from spray plate 66 of hand shower 65 to collect in bathtub main body 20 through opening 30A.

[0030] In the bathtub 10 of embodiment 1, the opening 30A is formed at the upper end of the fourth side wall 24 of the bathtub body 20 when the bathtub is suspended. This bathtub 10 can eject hot water from the opening 30A formed at the upper end of the fourth side wall 24 of the bathtub body 20. As a result, this bathtub 10 can prevent a drop in the temperature of the hot water stored in the bathtub body 20, and the hot water ejected from the opening 30A can easily hit the bather's shoulders and neck, giving the bather a comfortable bathing experience.

[0031] In the bathtubs 10, 110 of the first and second embodiments, the water discharge device is a hand shower 65, 165. In these bathtubs 10, 110, the hand shower 65, 165 used when washing the body can be used as a water discharge device to fill the bathtub main body 20 with hot and cold water.

[0032] The bathroom 50 in embodiments 1 and 2 is equipped with a hanging member 70 for suspending the bathtub 10, 110. This bathroom 50 can be used by hanging the bathtub 10, 110 from the hanging member 70, or the bathtub 10, 110 can be removed from the hanging member 70 and used as a shower room, etc.
