Japanese Patent Application Publication No. 2007-260180

In Patent Document 1, the bathtub body is supported by a support member extending from the floor. Therefore, the support member extends only from the floor to support the load of the bather and the hot water on the bathtub body. In this case, the support member is required to have a certain level of strength, and there is a concern that the support member will become larger. If the supporting members become larger, if you try to use the bathroom for purposes other than using the bathtub, such as taking a shower, the supporting members on the floor will get in the way even if you fold the bathtub body to make it more compact. It ends up.

The present disclosure has been made in view of the above-mentioned conventional circumstances, and aims to provide a bathroom that can be used space-efficiently when used for purposes other than the purpose of using the bathtub, and a bathtub suitable for this bathroom. Make it an issue to be solved.

In order to solve the above-mentioned problems, a bathroom according to an embodiment of the present disclosure includes a ceiling to which a deformable bathtub is attached to store hot water.

A bathtub according to an embodiment of the present disclosure is attached to the bathroom.

<Embodiment 1>
Embodiment 1, which embodies the bathroom and bathtub of the present disclosure, will be described with reference to the drawings. As shown in FIGS. 1 and 2, the bathroom 1 has a rectangular parallelepiped shape that is long in the vertical direction (vertical direction). As shown in FIG. 3, the bathroom 1 is adjacent to the washroom B on one of the four sides in plan view. The bathroom 1 forms a smaller space than the adjacent washroom B. Specifically, the specific dimensions of the bathroom 1 according to this embodiment are approximately 1600 mm in width, approximately 1200 mm in depth, and approximately 2200 mm in height when viewed from the washroom B side. On the other hand, the washroom B forms a space of about 2000 mm in length, which is connected to the bathroom 1 and has a width and height equivalent to the frontage and height of the bathroom 1.

As shown in FIGS. 1 and 2, the bathroom 1 includes walls W1, W2, W3, a ceiling C, and a floor F. The bathroom 1 is surrounded by walls W1, W2, and W3 on three sides except for the one adjacent to the washroom B in plan view. The bathroom 1 is sealed off by a ceiling C and a floor F at the upper and lower sides, respectively. The upper surface of the floor F extends substantially flush with the floor surface of the washroom B. The upper surface of the floor F is formed generally flat. Floor F has a slight slope so that hot water flows toward a drain port (not shown). The walls W1 and W2 are connected to the wall of the washroom B in substantially the same plane.

As shown in FIGS. 1 to 3, the bathroom 1 includes a partition P. The partition part P partitions off the washroom B so as to be openable and closable. The partition part P can open almost the entire frontage of the bathroom 1. By opening the partition part P, the bathroom 1 and the washroom B form one connected rectangular space in plan view.

As shown in FIGS. 1 to 3, the bathroom 1 is equipped with a shower device 2. The shower device 2 is arranged on the wall W1 among the walls W1, W2, and W3. The shower device 2 is arranged at a position closer to the wall W3 on the wall W1. The shower device 2 includes a faucet 3, an overhead shower 4, and a hand shower 5. The faucet 3 is formed into a long cylindrical shape that extends horizontally along the wall surface of the wall W1. The faucet 3 is connected to a water supply pipe and a hot water supply pipe (not shown) within the wall W1. The faucet 3 is a mixed faucet. The faucet 3 can adjust the amount of water, adjust the temperature by mixing hot water and water, stop water discharge, and the like. In this specification, hot water or water supplied from a faucet placed in a bathroom is referred to as hot water regardless of temperature, mixing ratio, etc.

As shown in FIG. 4, the faucet 3 forms a water outlet 3A. The spout 3A is formed in the shape of a long slit along the axial direction of the faucet 3. The water flow discharged from the water spout 3A has a horizontally long thin film shape. The faucet 3 can discharge hot water into the bathtub 10 from the spout 3A when a bathtub 10 (described later) is attached to the bathroom 1. The faucet 3 can select one of the spout 3A, the overhead shower 4, and the hand shower 5 to discharge hot water.

As shown in FIGS. 1 and 2, the overhead shower 4 is provided above the faucet 3. Overhead shower 4 is connected to faucet 3 via piping 6. The pipe 6 extends vertically upward from the faucet 3 along the wall surface of the wall W1, and is bent toward the inside of the bathroom 1 at its upper end. The overhead shower 4 is provided at the tip of this pipe 6. The hand shower 5 is connected to the faucet 3 via a hose 7. The hand shower 5 can be used movably within the length of the hose 7.

A bathtub 10, which will be described later, is attached to the ceiling C of the bathroom 1. The bathtub 10 is suspended from a ceiling C. In the case of this embodiment, the bathtub 10 is attached to the ceiling C and the wall W1. As shown in FIG. 3, the bathtub 10 is arranged in a recessed position in the bathroom 1 when viewed from the washroom B side, and closer to the wall W3 than the partition P (washroom B). When the bathtub 10 is attached to the ceiling C and the wall W1, a space that can be used as a washing area is formed on the partition P side seen from the bathtub 10.

The ceiling C has a mounting member 20. The attachment member 20 is attached by hooking a part of the bathtub 10. In the case of this embodiment, the mounting member 20 is formed into an elongated cylindrical shape, as shown in FIG. The mounting portions 21 are formed in a groove shape at both ends of the mounting member 20 in the longitudinal direction. The attachment portion 21 removably attaches a bathtub side attachment portion 10A to the bathtub 10, which will be described later. The attachment member 20 is connected to the lower end of a rope 22 suspended from the ceiling C. The upper end of the rope 22 is connected to a reinforcing structural material (not shown) on the ceiling or attic, a building frame, etc., to ensure sufficient strength to suspend the bathtub 10.

In the case of this embodiment, the faucet 3 also functions as a mounting member on the wall W to which the bathtub 10 is attached. The faucet 3 as a mounting member is attached by hooking a part of the bathtub 10 in the same manner as the mounting member 20. As shown in FIG. 4, the faucet 3 has a mounting portion 21. As shown in FIG. The attachment portions 21 are provided at both ends of the faucet 3 in the longitudinal direction. The mounting portion 21 is formed by reducing the diameter of the peripheral wall of the cylindrical faucet 3 into a groove shape. The mounting portions 21 at both ends of the faucet 3 have a water spout 3A sandwiched between them.

As described above, the bathtub 10 is detachably attached to the ceiling C and the wall W1. That is, when using the bathroom 1 for the purpose of not using the bathtub 10, the bathtub 10 can be removed and used. For example, as shown in FIG. 2, the bathroom 1 can be suitably used as a shower room by removing the bathtub 10.

The bathtub 10 is detachably attached to the ceiling C and the wall W1. As shown in FIG. 6, the bathtub 10 has a bathtub-side attachment portion 10A. The bathtub side attachment part 10A is detachably attached to an attachment member 20 provided on the ceiling C and a faucet 3 provided on the wall W1. The bathtub-side attachment portion 10A is provided at the upper edge of the bathtub 10. The bathtub-side attachment portion 10A corresponds to at least a portion of the upper edge of the bathtub according to the present disclosure, and is hooked and attached to the attachment member 20. That is, the bathtub 10 is suspended from the attachment member 20 and the faucet 3 at the bathtub-side attachment portion 10A, which is at least a portion of the upper edge. The bathtub 10 is deformed to store hot water. The bathtub 10 can freely change its shape, such as a folded state or an expanded state. The bathtub 10 stores hot water in an expanded state.

As shown in FIG. 6, the bathtub 10 of this embodiment includes a seat portion 11 and a rope 12. The seat portion 11 stores hot water. The seat portion 11 is made of a sheet. The sheet portion 11 has flexibility. The sheet portion 11 is formed into a boat shape that is rectangular in plan view by cutting, joining, etc. a flexible waterproof sheet. The seat portion 11 of this embodiment has poor elasticity and maintains its boat-shaped shape to some extent when filled with hot water.

The rope 12 is provided in an annular shape along the upper edge of the seat portion 11 . In the installed state of the bathtub 10, the outer edge of the seat portion 11 is suspended from the rope 12. The rope 12 constitutes a bathtub side attachment part 10A. The rope 12 also functions as a reinforcing section that reinforces the sheet section 11. As a result, the seat portion 11 has a boat shape with an outer edge serving as an upper edge and a center portion concave downward. In the state in which hot water is stored, the lower center surface of the seat portion 11 contacts the floor F of the bathroom 1. Thereby, the bathtub 10 can support most of the load on the floor F when filled with hot water. Therefore, compared to the case where the bathtub 10 is supported only by the ceiling C and walls W, the reinforcement structure for each of the ceiling C and walls W can be simplified.

As shown in FIG. 7, the rope 12 is inserted into a folded portion 11A at the upper edge of the sheet portion 11. As shown in FIG. The folded portion 11A is formed by folding back the outer edge of the sheet portion 11 into a cylindrical shape. The folded portion 11A is formed over the entire circumference of the upper edge of the sheet portion 11. The folded portions 11A are divided at the four corners of the bathtub 10, which is rectangular in plan view. The ropes 12 are exposed to the outside at the four corners of the sheet portion 11. The bathtub 10 is detachably attached to the ceiling C and the wall W1 by hooking the rope 12 exposed from the seat section 11 onto the attachment section 21 in this manner. Since the folded portion 11A is folded back to have a double structure, it also functions as a reinforcing portion at the upper edge of the sheet portion 11.

As shown in FIG. 5, the bathtub 10 of this embodiment has a drainage section 13. The drainage section 13 is configured by providing an opening in the lower part of the seat section 11 that can be opened and closed using a waterproof slide fastener. Thereby, the bathtub 10 can easily discharge the stored hot water to the outside of the bathtub 10.

The functions and effects of the bathroom 1 and bathtub 10 having the above configuration will be explained. The bathroom 1 includes a ceiling C and a wall W1 to which a bathtub 10 is attached. Therefore, in the bathroom 1, at least part of the load applied to the bathtub 10 can be supported by the ceiling. When taking a bath in the bathroom 1, the bathtub 10 is transformed into a state for storing hot water, as shown in FIG. Specifically, in the case of this embodiment, the bathtub 10 can freely change its shape between a folded state and an expanded state. The bathtub 10 is expanded when storing hot water. When the bathtub 10 is not filled with hot water, it can be kept in a more compact state than when it is deformed into a shape for storing hot water. Specifically, the bathtub 10 can be kept in a folded state when not filled with hot water.

In this embodiment, the bathtub 10 is detachably attached to the ceiling C and the wall W1. Therefore, the bathtub 10 can be installed and stored extremely easily. When installing the bathtub 10, the bathtub 10 is installed using a simple method in which the ropes 12 exposed at the four corners are attached as the bathtub side attachment parts 10A to the attachment members 20 on the ceiling C and each attachment part 21 of the faucet 3 on the wall W1. be able to. By appropriately attaching the bathtub-side attachment portion 10A to the attachment portion 21, the bathtub 10 is suitably transformed into an expanded state for storing hot water.

To store hot water in the bathtub 10, a faucet 3 in the shower device 2 is used. As shown in FIG. 4, the faucet 3 can discharge a thin film of hot water from the spout 3A. When taking a bath using the bathtub 10, the user can bathe the nape of the neck and shoulders in the bathtub 10 with a thin film of hot water discharged from the spout 3A. The user can fill the bathtub 10 with hot water while taking a bath from the spout 3A. Since the bathtub 10 is deformable, it can be shaped to fit the user's body. Therefore, the bathtub 10 can store less hot water than a non-deformable bathtub.

When the bathtub 10 is filled with hot water, force due to the water pressure of the stored hot water acts on each part of the bathtub 10. Due to the action of this water pressure, each part of the bathtub 10 is deformed, and the seat part 11 and the rope 12 are put into a tensioned state. In particular, the rope 12 constituting the upper edge of the bathtub 10 is tightly stretched to the extent that it does not shake significantly even when you place your hand on it. Therefore, although the bathtub 10 is deformable, deformation is suppressed by storing hot water, and a stable shape can be maintained even when the user enters and exits the bathtub 10.

The lower surface of the central portion of the bathtub 10 contacts the floor F when hot water is stored therein. As the lower surface of the bathtub 10 contacts the floor F in this way, the weight of the hot water stored in the bathtub 10 and the user's own weight are suitably supported by the floor F. This prevents excessive load from being applied to the mounting portion 21. Therefore, in the bathroom 1, the structure of the walls and ceiling and the structure of the mounting members can be simplified in terms of strength, compared to, for example, a structure in which the bathtub is supported only by the walls or ceiling.

When the bathtub bath is finished, the hot water stored in the bathtub 10 is drained from the drain section 13. Specifically, in the case of this embodiment, the fastener in the drain section 13 is opened to drain hot water. As mentioned above, the bathtub 10 deforms to store hot water. Therefore, the bathtub 10 can be deformed from a shape for storing hot water to another shape by changing the state from a state in which hot water is stored to a state in which water is removed. After draining hot water, the bathtub 10 can be folded by removing the ceiling C and wall W1. The bathtub 10 can be easily stored by folding it in this manner. Both sides of the bathtub 10 are attached to the ceiling C and the wall W1, and no separate floor-standing mounting member is provided, so that the bathroom 1 can be used space-efficiently simply by storing the bathtub.

When removing the bathtub 10 from the ceiling C and the wall W1, the bathtub 10 can be removed by a simple operation such as removing the rope 12, which is the bathtub side attachment part 10A, from the attachment part 21. The removed bathtub 10 is washed, dried, folded and stored. Since the bathtub 10 is removable, the entire inner and outer surfaces of the bathtub 10 can be washed, unlike conventional stationary bathtubs. Since the bathtub 10 is made of a flexible and deformable sheet-like material, it can be washed, dried, and folded just like laundry. In the bathroom 1 with the bathtub 10 removed, a flat floor F is exposed. Therefore, the floor F of the bathroom 1 is easy to clean, and cleanliness is easy to maintain. Since the bathtub 10 is flexible and deformable, for example, by placing a chair, bench, cushion, etc. between it and the floor F, the bathtub 10 can be bathed in a desired posture. A massage device or a heater may be placed between the bathtub 10 and the floor F. Since these devices are placed outside the bathtub 10, they do not need to be waterproof.

The bathtub 10 with hot water and water removed may be hung together on one of the ceiling C and the wall W1, for example. In the bathroom 1, the bathtub 10 is installed in an expanded state in both the state where the bathtub 10 is removed from the walls W1 and W2 and the state where the bathtub 10 is hung together on one of the walls W1 and W2. It can be used as a relatively wide space with the entire floor F exposed when it is not covered.

As shown in FIG. 2, the bathroom 1 is suitable for taking a shower, for example, when the bathtub 10 is removed. In the bathroom 1, when the bathtub 10 is not attached, the entire floor F can be used as a washing area for taking a shower. In the bathroom 1, a shower can be taken using at least one of the overhead shower 4 and the hand shower 5 in the shower device 2. The bathroom 1 has a width of 1,600 mm and a depth of 1,200 mm, which is a larger space than a conventional general shower room or washing area, and allows the user to enjoy a relaxing shower bath. When taking a shower with the bathtub 10 removed, bubbles and water do not adhere to the bathtub 10 in the bathroom 1. Therefore, the bathroom 1 is easy to clean after taking a shower.

Since the bathtub 10 is detachable, it can also contribute to making the bathtub barrier-free. For example, the bathtub 10 is placed on the floor F before being attached to the attachment member 20 and the faucet 3. The user stands on the bathtub 10 in this state. Thereafter, by attaching the bathtub-side attachment part 10A of the bathtub 10 to the attachment part 21 and filling it with hot water, the user can take a bath without stepping over the upper edge of the installed bathtub 10. According to such a bathing method, even users who have difficulty stepping over the upper edge of the bathtub 10 or users in wheelchairs can easily bathe in the bathtub.

As shown in FIG. 8, the bathroom 1 can form one space connected to the washroom B by opening the partition P. The space created by this is larger than the space created by the bathroom 1 alone. The space thus formed can be used for multiple purposes, such as a fitness room, laundry room, etc., which require a larger space.

Since the bathtub 10 is made of a flexible sheet, it is easier to manufacture at a lower cost than conventional bathtubs made of FRP or the like. Therefore, it is relatively easy to provide a dedicated bathtub 10 for each user. In this case, the size, design, etc. of the bathtub 10 can be freely set according to each user. The bathtub 10 is advantageous in terms of transportation cost, recyclability, etc. compared to conventional stationary bathtubs made of FRP or the like. Therefore, the bathtub 10 can reduce the environmental load. It is relatively easy for one user to own a plurality of such bathtubs 10. In this case, the user can select and use a desired bathtub 10 from a plurality of bathtubs 10 depending on the mood, season, etc., just like selecting clothes.

As described above, the bathroom 1 according to the first embodiment includes the ceiling C. A bathtub 10 is attached to the ceiling C. The bathtub 10 is deformed to store hot water.

In the bathroom 1, the bathtub 10 is attached to the ceiling C, so the bathtub 10 is less likely to get in the way, compared to, for example, a conventional floor-standing bathtub. The bathtub 10 deforms when in use to store hot water. When the bathtub 10 is not in use, it can be transformed into a more compact state than when in use. Therefore, the bathroom 1 can be used with good space efficiency when used for purposes other than the purpose of using the bathtub 10.

In the bathroom 1, the bathtub 10 can change its shape into a folded state and an unfolded state, and stores hot water in the unfolded state. That is, the bathtub 10 can be in a folded state when not in use and does not store hot water. Therefore, the bathroom 1 can be used with good space efficiency by keeping the bathtub 10 in a folded state when not in use.

In the bathroom 1, the ceiling C has a mounting member 20. The attachment member 20 detachably attaches the bathtub 10. For this reason, the bathroom 1 can form a large space by removing the bathtub 10, for example, when taking a shower. That is, the bathtub 10 can be attached to the bathroom 1 only when the bathtub 10 is needed, and the bathtub 10 can be removed when the bathtub 10 is not needed. Therefore, when the bathroom 1 is to be used for a purpose other than the purpose for which the bathtub 10 is used, by removing the bathtub 10, the bathroom 1 can be used more space efficiently due to the absence of the bathtub 10. It is desirable that the bathroom 1 is a waterproofed space using waterproof pans on the floor. In that case, in addition to being a shower room, the waterproof space can be used for multiple purposes such as caring for houseplants or doing hot yoga.

In the bathroom 1, the attachment member 20 suspends the bathtub 10 at a bathtub side attachment portion 10A that is at least a part of the upper edge of the bathtub 10. Therefore, the bathroom 1 can be stably attached to the ceiling C even if the bathtub 10 deforms.

In the bathroom 1, a bathtub 10 is suspended from a mounting member 20 provided on a ceiling C. Therefore, when the bathtub 10 is installed in the bathroom 1 and used as a bathroom, the bathroom 1 can create an unusual feeling of being a suspended bathtub. In the bathroom 1, by providing the faucet 3 as a mounting member on the wall W1 side, the number of members that function only as a mounting member can be reduced. Therefore, the bathroom 1 can achieve a neat design as a whole.

The bathtub 10 according to the first embodiment can be suitably attached to the bathroom 1.

The bathroom 1 according to the first embodiment includes a wall W1. The wall W1 has a faucet 3 as a mounting member for mounting the bathtub 10. Therefore, in the bathroom 1, the number of members that function only as attachment members can be reduced, and a clean design can be achieved as a whole. In the bathroom 1, by making the mounting member 220 on the wall W2 side have a shape that imitates the water faucet 203, the designs of the two mounting members are harmonious and a clean aesthetic appearance can be achieved.

<Embodiment 2>
The bathroom 201 according to the second embodiment is different from the first embodiment in that the bathtub 10 is attached only to the ceiling C, as shown in FIG. In the bathroom 201, the entire bathtub 10 is suspended from the ceiling C by one mounting member 220. The mounting member 220 is formed in an elongated cylindrical shape that is longer than the mounting member 20 of the first embodiment, and is provided with mounting portions 21 at both ends. In the present embodiment, in the bathtub 10, all of the four bathtub-side attachment parts 10A are attached to either of the attachment parts 21 at both ends of the attachment member 220. In the bathroom 201, the bathtub 10 is configured so as not to come into contact with the floor F even when filled with hot water. The mounting member 220 is connected to the ceiling C by a rope 222. The rope 222 branches into two at its lower end and is connected to both ends of the attachment member 220. As a result, the mounting member 220 has improved stability against tilting compared to the mounting member 20 of the first embodiment.

Similarly to the first embodiment, the bathroom 201 according to the second embodiment having the above configuration can be used with good space efficiency when used for purposes other than the purpose of using the bathtub. Since the bathtub 10 is suspended and attached to the bathroom 201 using only one mounting member 220, a bathroom with a neat design can be realized. In the bathroom 201, the bathtub 10 does not come into contact with the floor F even when filled with hot water. Therefore, the user can bathe in the bathtub in the bathroom 201 with an unprecedented feeling of floating.

The inner surface of the drainage part 1613 is tightly adhered with an adhesive material or the like, and is closed so that water cannot be easily discharged from the pipe. When hot water is stored in the bathtub 1610, the bathtub 1610 is further pressurized and closed, thereby preventing the hot water from being discharged. The drain section 1613 can drain hot water in the bathtub 1610 to the outside by opening against water pressure.

The drainage section may have a form as shown in FIG. 32, for example. A drainage section 1713 shown in FIG. 32 is provided integrally with the seat section 1711. Drainage section 1713 is formed into a tubular shape that projects outside of bathtub 1710. The tubular drainage portion 1713 is bendable. The drain portion 1713 is formed with a length that allows its tip to be placed above the water surface level when hot water is stored in the bathtub 1710. By arranging the distal end of the drain section 1713 above the water surface, hot water can be prevented from being discharged, and hot water can be maintained in the bathtub 1710. The drain section 1713 can easily drain the hot water in the bathtub 1710 by arranging its tip below the water surface.

The drainage portion may have a form as shown in FIG. 33, for example. A drain section 1813 shown in FIG. 33 is provided in the bathtub 1810. The drainage portion 1813 has a configuration in which an opening 1813A formed at the bottom of the seat portion 1811 is closed by a float valve 1813B. The float valve 1813B can close the opening 1813A with water pressure when hot water is stored in the bathtub 1810. The float valve 1813B is connected via a chain to a wall-mounted operating lever 1813C. Float valve 1813B opens opening 1813A by operating control lever 1813C. The float valve 1813B with the opening 1813A open maintains that state due to buoyancy. Float valve 1813B closes opening 1813A again when hot water in bathtub 1810 is discharged.
