Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub partitioning tool which can easily perform two types of bathing, water and hot water, and a two-tub type bathtub using the same.

[0002]

2. Description of the Related Art In recent years, as a method for promoting health, a method has been proposed in which two baths having different temperatures are alternately used for bathing. The most typical method is to alternately repeat a hot water bath with a normal bath temperature and a hot water bath.By such a bathing method, blood circulation and metabolism of the body can be promoted, and sympathetic nerves can be stimulated. It is said to be effective in recovering and improving functions, preventing colds, and improving constitution such as allergies. On the other hand, a bathtub structure capable of realizing such a bathing method has already been proposed as a two-tank bathtub in, for example, Japanese Utility Model Publication No. 57-163252 and Japanese Utility Model Publication No. 1-119583.

[0003]

However, such a conventional bathtub structure has a problem that it cannot be easily realized, for example, in an existing domestic bathtub. That is,
The one described in Japanese Utility Model Publication No. 57-163252 has a structure in which two ordinary household bathtubs are arranged side by side, which cannot be easily implemented in a general house having a small bathroom area, and also in terms of space. Even if it was possible, another new bathtub had to be created separately, and it could not be carried out easily. In addition, the actual Kaihei 1-11958
The one described in No. 3 is one in which a partition is provided in one bathtub, and it can be carried out without providing two bathtubs. However, when assuming an existing bathtub of a general household, for example, by providing a partition The space for one tank becomes small, and it is very difficult to take a bath. The object of the present invention is to solve these problems, to be able to easily attach / detach to / from existing household bathtubs, and in addition, a bathtub partitioning tool that does not make it difficult to bathe in terms of space, and a two-tank type using it It is in the area of providing a bathtub.

[0004]

In order to solve the above problems, the present invention mainly provides eight types of bathtub partitioning tools and a two-tub type bathtub using these. First, the first bathtub partitioning tool is a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and a sheet-shaped partitioning member made of a flexible material having water impermeability at the opening of the substantially rectangular frame body having an opening in the center. The second bathtub partitioning tool is a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and is made of a material having a water-blocking property. Of the bottomed substantially rectangular container, and one of two surfaces facing each other in one direction,
The third bathtub partitioning tool is provided with a fixing means capable of being attached to and detached from the bathtub, on the outside of at least one surface selected from two surfaces facing each other in the other direction. Three
The suction cup is used as a fixing means for any one of the bathtub partitioning tools, and the fourth bathtub partitioning tool is a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and is a bottomed rectangular container made of a material having water-blocking properties. The fifth bathtub partitioning tool is a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and has a bellows-like foldable and foldable in one direction. A single or a plurality of shape-retaining core materials are installed on two bottom surfaces of a bottomed rectangular container made of a material having a
The bathtub partitioning tool of is a bottom surface of the bottomed rectangular container in the fourth bathtub partitioning tool or the fifth bathtub partitioning tool, and one of two surfaces facing each other in one direction and the other direction. A fixing means capable of being attached to and detached from the bathtub is provided on the outside of at least one kind of surface selected from two surfaces facing each other, and the seventh bathtub partitioning tool is the sixth bathtub partitioning tool. A suction cup is used as the fixing means of the second bathtub partitioning tool, and the eighth bathtub partitioning tool has shape-retaining plates attached to two surfaces of the fourth to seventh bathtub partitioning tools that face each other in one direction, A ninth bathtub partitioning device is characterized in that the water-blocking material in any one of the first to eighth bathtub partitioning devices is a laminated body of a water-blocking material and a foaming material. There is.

As a two-tub type bathtub,
Each of the first to ninth bathtub partitioning tools is attached to the bathtub partitioning tool.

[0006]

The above structure has the following functions. First, the first bathtub partitioning tool is a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and a sheet-shaped partitioning member made of a flexible material having water impermeability attached to an opening of a substantially rectangular frame body having an opening at the center is Since it is stretchable, it expands when the limbs of the bather hit it, thus expanding the bathing space. Further, the fixing means which is provided in the frame body and which can be attached to and detached from the bathtub performs fixed support between the frame body and the bathtub. Second
The bathtub partitioning tool of is also a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and the bottomed substantially rectangular container made of a material having water blocking property is
When the bathtub is empty, the bathtub is preliminarily mounted in the bathtub, and hot water is put in the bathtub at the same time, and water is put in the substantially rectangular container with a bottom at the same time to form a two-tub bathtub. And it is provided on the outside of at least one surface selected from the bottom surface of the bottomed substantially rectangular container, one of the two surfaces facing each other in one direction, and the two surfaces facing each other in the other direction. Further, the bottomed substantially rectangular container is fixed to the inner wall of the bathtub by a fixing means capable of being attached to and detached from the bathtub. As a third bathtub divider,
The use of the suction cup as the fixing means simplifies the attachment / detachment work to / from the bathtub. The fourth bathtub partitioning tool is also a bathtub partitioning tool to be mounted on the inner surface of the bathtub, and the bottomed rectangular container made of a material having a water-blocking property is preliminarily mounted in the bathtub when the bathtub is empty. A two-tank bath is constructed by pouring hot water into the tank and water into the substantially rectangular container with a bottom at the same time. Further, the bellows-shaped fold provided on the bottomed substantially rectangular container enables the bottomed substantially rectangular container to be folded in one direction. The fifth bathtub partitioning device is also a bathtub partitioning device that is mounted on the inner surface of the bathtub, and the bottomed rectangular container made of a water-blocking material that is accordion-shaped and capable of expanding and contracting in one direction is used in advance when the bathtub is empty. A two-tank type bathtub is constructed by mounting it in a bathtub, and simultaneously pouring hot water into the bathtub and water into the bottomed substantially rectangular container. Further, the shape-maintaining core material, which is installed inside the bottomed rectangular container across two surfaces and the bottom surface which are orthogonal to each other in the direction of expansion and contraction, performs the shape-retaining action of the bottomed rectangular container. In the sixth bathtub partitioning tool, the bottom surface of the bottomed rectangular container in the fourth bathtub partitioning tool or the fifth bathtub partitioning tool, and one of the two surfaces facing each other in one direction, Fixing means which is provided on the outside of at least one kind of surface selected from two surfaces facing each other in the other direction and which is attachable to and detachable from the bath tub adsorbs and fixes the bottomed substantially rectangular container to the inner wall of the bath. . Use of a suction cup as the fixing means as the seventh bathtub partitioning tool simplifies attachment / detachment work to / from the bathtub. In the eighth bathtub partitioning tool, the fourth bathtub partitioning tool or the fifth bathtub partitioning tool,
Alternatively, the shape-retaining plates attached to the two surfaces of the sixth bathtub partitioning tool or the seventh bathtub partitioning tool that face each other in one direction perform the shape-retaining action of the bottomed rectangular container.

As the ninth bathtub partitioning tool, the water-blocking material in any one of the first to eighth bathtub partitioning tools is a laminate of the water-blocking material and the foam material. Therefore, it is possible to obtain the effect of preventing the heat from propagating from the hot water tank side to the water tank side. Therefore, for example, even if the bath is heated in a state where the side opposite to the heating port of the bathtub is the water tank, heat can be prevented from propagating from the hot water tank side to the water tank side. Furthermore, when these bathtub partitioning tools are installed in an existing bathtub, for example, first to third
And even if the water-tight seal between the frame and the bathtub is not perfect like the ninth bathtub partitioning tool, the convective movement of hot and cold water between the two separated baths is small, so it is possible to use a flexible material. The water temperature on the side of the aquarium does not rise in combination with the effect of preventing heat transmission.

The bathtub partitioning tool as described above can be used in the following manner. First, in a bathtub in which water is added and then reheated, water is simultaneously poured into two tanks separated by the partitioning tool, with the partitioning tool installed in an empty bathtub. And when installing, except for the first partitioning tool, it is installed on the opposite side of the bathtub opening. That is, the bottomed substantially rectangular container that constitutes the partitioning tool becomes the water-side bathtub. Ignite the bath and boil the bath. Then, as described above, due to the heat insulating effect of the flexible material, only the hot water tank side, that is, the heating port side becomes hot water, and the two-tank type bath is completed.

Next, the two-tub type bathtub using any one of the first to ninth bathtub dividers has an excellent effect by the above-mentioned bathtub dividers, but when it is desired to enjoy the conventional bathing only with hot water. , Remove the bathtub divider to use.

[0010]

EXAMPLES Next, the structure of the bathtub partitioning tool and the two-tub type bathtub according to the present invention will be described in detail based on specific examples. First, in FIG. 1, the structure of the first bathtub partitioning tool 1 is (a) as a front view, and (b) as A in (a).
It is represented by using a cross-sectional view taken along line A. In the example shown in the figure, a sheet-shaped partition member 7 made of a flexible material having water-blocking property is attached to the opening 5 of the substantially rectangular frame 3 having an open central portion, and the upper part of the frame 3 is connected to the bath 9. The hook member 11 is provided as a fixing means that enables attachment and detachment of the hook. As the flexible material having water impermeability, a synthetic resin sheet or film or a fiber cloth impregnated with or coated with a synthetic resin or the like is sandwiched with a foam such as polyurethane, polyvinyl chloride, polyolefin, or synthetic rubber foam. A laminated body having a structure can be exemplified, and further, an air layer can be provided in the middle in order to enhance the heat insulating property and heat retaining property of the foamed product. Then, as shown in FIG. 2B, a water tank 13 and a hot water tank 1 are provided on the left and right of the first bathtub partitioning tool 1.
5, respectively. This hook member 11 prevents the first bathtub partitioning tool 1 from collapsing by hooking it on the upper edge 17 of the existing bathtub 9, as shown in FIG.
The frame body 3 may be suction-fixed to the inner wall surface of the bathtub 9 by a plurality of suction cups 19 as shown in the figure so as not to shift when a force in the arrow direction shown in (b) is applied. This drawing shows an example in which the suction cup 19 is attached to the frame body 3, but as shown in FIG. 2, instead of being provided on the frame body 3, it may be provided on the hook member 11 and fixed to the upper edge 17 of the bath by suction. . In order to fix it more securely, the hook member 1
It goes without saying that suction cups 19 as fixing means may be provided on both 1 and the frame body 3. Also, bathtub divider 1
As the fixing means capable of attaching and detaching, in addition to the use of the hook member 11 and the suction cup 19 as described above, mechanical fixing with a fastener, light adhesive fixing with an adhesive or an adhesive sheet, or the bath 9 It is possible to use an elastic body provided on the outer periphery of the frame body 3 of the bathtub partitioning tool 1 that is in contact with the bathtub partitioning tool, and press-fixing to fix the elastic body by the elastic repulsive force, fitting fixing to provide an engaging groove in the bathtub 9, and the like. It is also possible to use one kind or a combination of two or more kinds. Therefore, a fastener, an adhesive sheet, or the like may be used instead of the suction cups 19 shown in FIG.

Further, as shown in FIG. 3, the first bathtub partition 1
It is also effective to provide the frame body 3 with a water blocking member 3c made of a flexible material such as rubber for the purpose of suppressing the flow between the water tank 13 side and the hot water tank 15 side. It should be noted that this drawing shows the main part of the BB cross section in FIG. 1.

As shown in FIG. 4, the engaging groove 63 is provided in the inner surface of the bathtub 9 as the fixing means, as shown in FIG. The frame body of the bathtub partitioning tool 1 in which a sheet-like partitioning member 7 made of a flexible material having water impermeability is attached to the engaging groove 63 at the opening 5 of the substantially rectangular frame body 3 having an open central portion. When 3 is inserted, the two-tank type bathtub 65 in the illustrated example
Becomes In this case, since the frame body 3 is fitted into the engagement grooves 63 provided on the two side surfaces 61, 61 facing each other on the inner surface of the bathtub 9, the suction means such as the suction cups 19 ... Is not provided as described above. Good, and it is also possible to more reliably ensure water impermeability between the two tanks. This groove is formed by the two side surfaces 61,
It may be provided over 61 and the bottom surface 67. Alternatively, as shown in FIG. 5, the inner wall of the bathtub 9 may be provided with a concave engagement groove 63 with respect to the inner wall surface.

As the fixing means, an elastic body is provided on the outer periphery of the first bathtub partitioning tool 1 for the bathtub 9, and pressure fixing for fixing by the repulsive force of the elastic body is shown in FIG. The example shown in the figure is a sheet sandwiching two rubber sheets 7c and 7c and an elastic foamed body 7d by two substantially rectangular frame bodies 3a and 3b having an opening at the center as shown in FIG. A bathtub partitioning tool 1 in which a sheet-shaped partitioning member 7 is sandwiched, and the elastic foamed body 7d of the sheet-shaped partitioning member 7,
Has a structure protruding from the outer peripheral portion of the frame body 3. When such a bathtub partitioning tool 1 is pushed into the bathtub 9, the protruding portion 7a is compressed into a close contact state with the bathtub 9, and the elastic repulsive force causes the bathtub partitioning tool 1 to move the bathtub partitioning tool 1 into the bathtub 9.
Will be fixed against. Note that this example is an example in which a foam is used as an elastic body, but a rubber body having elasticity may be used, and in addition to being sandwiched between the two frame bodies 3a and 3b,
It may be attached to the periphery of the frame body 3 later.

The sheet-shaped partition member 7 provided in the first bathtub partitioning tool 1 is shown in FIG. 7 in addition to the flat plate-shaped partition member shown in FIGS. As shown in the figure, it is also possible to use one which is preformed into a substantially hemispherical bowl shape so that the concave portion 7b can be inverted between the one surface side and the other surface side of the bathtub partitioning tool 1. By doing this,
When entering one bathtub, the other side becomes a convex part (7b),
It is possible to secure a wider bathtub space on the entry side. It should be noted that such a substantially hemispherical concave portion 7b has a second
-Of course, it is also possible to use it for the boundary wall part which divides into 2 tanks in the 9th bathtub partitioning tool.

Next, FIG. 8 shows a second bathtub partitioning tool 21.
The structure of is shown by a perspective view. In the example shown in the figure,
At least one surface selected from the bottom surface, one of the two surfaces facing each other in one direction, and the two surfaces facing each other in the other direction of the bottomed substantially rectangular container 23 made of a material having water-imperviousness. As one kind of surface, two side surfaces 25, 25 on the side wall side of the existing bathtub 9 (represented by a dotted line) and a bottom surface 27, a total of three surfaces, are provided as a plurality of suction cups as fixing means capable of being attached to and detached from the bathtub 9. It has a structure with 19 ... Separately from the example of this drawing, this suction cup 19 ...
It may be attached to a total of two side surfaces 29 on the end surface side of
It may be attached to all four surfaces except the side surface 31. Also in this example, other fixing means such as a fastener or an adhesive tape can be used alone or in combination as described above.

Since the second bathtub partitioning device 21 has a substantially rectangular container structure with a bottom and is made of a water-impervious material, when it is installed in the existing bathtub 9 to drain water, it is It is desirable to pour water on the existing bathtub 9 side and the bathtub partitioning tool 21 side at the same time so as not to deform. As the material having a water-blocking property, a synthetic resin or rubber film or sheet, or a fiber cloth impregnated with or coated with a synthetic resin or the like can be used as described above. in this case,
Water may be poured from the two faucets at the same flow rate at the same time, but since there is usually only one faucet in the bathroom in most ordinary households, it is not a desirable method considering the effort. For this reason, as shown by the phantom line in the figure, it is convenient to supply and drain water when a stopper 33 is provided near the bottom of the bottomed substantially rectangular container 23 and is closed after the completion of water injection.

Among the first and second bathtub partitioning tools 1 and 21, the one using the suction cup 19 as the fixing means is positioned as the third bathtub partitioning tool.

Next, FIGS. 9 to 11 show the structure of an eighth bathtub partitioning tool 37 based on the fourth bathtub partitioning tool 35. In the example shown in the drawing, the bottomed substantially rectangular container 23 made of a material having a water-impervious property is provided with bellows-shaped folds 39 ... As shown in the plan view of FIG. The eighth bathtub partitioning tool 37 is formed by additionally attaching shape retaining plates 41, 41 to the two surfaces of the bathtub partitioning tool structure 35 that face each other in one direction. The shape-retaining plates 41, 41 need only have appropriate rigidity, heat resistance, and heat insulation properties, as well as appropriate specific gravity and corrosion resistance that do not generate large buoyancy, and can be made of metals such as aluminum and stainless steel,
Examples thereof include synthetic resins called engineering plastics, wood, and combinations thereof.
In the example of this figure, the shape-retaining plate 41 is replaced by an outer plate 41a and an inner plate 41.
b has a double structure, and the side surfaces 29, 3 of the bottomed substantially rectangular container 23
It has a structure in which 1 is sandwiched. But as a single plate,
A structure may be used in which the side surfaces 29 and 31 are attached. In addition, as a shape-retaining plate 41, a laminate obtained by laminating a flexible material to the metal, engineering plastic, wood, or the like may be used as a shape-retaining plate 41, and two surfaces facing each other in one direction may be used. Instead of the above, a sheet-shaped partitioning member 7 made of a flexible material having water impermeability may be attached to the opening 5 of the substantially rectangular frame body 3 having an open central portion. What is shown is the eighth as described above.
If the bottomed substantially rectangular container 23 has a certain shape retention property, the shape retention plates 41, 41 attached to the two side surfaces 29, 31 are removed to obtain a fourth bathtub partitioning tool. 35. FIG. 11 shows a state where the bathtub 9 is attached to the existing bathtub 9. In the figure, (a) shows a state in which the folds 39, ... Are extended during use, and (b) shows a folded state. In this way, the fourth and eighth bathtub dividers 35, 37 are folded along the folds 39, ... Formed in a bellows shape, so that they are compact and compact even when a relatively thick flexible material is used. Can be folded. Further, as indicated by a virtual line in the figure, the bottom surface 27 of the bottomed substantially rectangular container 23, one of the two surfaces facing each other in one direction, and the two surfaces facing each other in the other direction. As a fixing means capable of being attached to and detached from the existing bathtub 9, on the outside of at least one surface selected from
Suckers 19 ... Can be provided. Here, as the surface, a back surface 29 on the end surface side of the existing bathtub 9 is one of two surfaces facing each other in one direction, and a side surface 25 is two surfaces facing each other in the other direction. , 25, and the bottom surface 27. Here, if the structure having only the fixing means is provided without providing the shape-retaining plates 41, 41, a sixth bathtub partitioning tool is provided, and specifically, if the suction cups 19 ... Are provided as the fixing means, It becomes the seventh bathtub divider. When the suction cups 19 ... Are used as the fixing means that can be attached to and detached from the bathtub, the bellows may be extended during use and then pressed against the inner surface of the existing bathtub 9 to be fixed by suction. Further, similarly to the above, as shown by an imaginary line in the figure, it is convenient to supply and drain water when a stopper 33 is provided near the bottom of the bottomed substantially rectangular container 23, and after the completion of water injection, the stopper 33 is closed and then heated. .

Continuing with FIG. 12, a fifth bathtub divider 43 is shown.
The structural example of the 7th bathtub partitioning tool 45 based on FIG. In the example shown in the figure, a bottomed substantially rectangular container 23 made of a flexible material that has a bellows shape and is capable of expanding and contracting in one direction has a water shielding property, and has two side surfaces 25, 25 and a bottom surface 27 that face each other at right angles to the expanding and contracting direction. In addition to the bathtub partitioning structure in which one or a plurality of shape-retaining core materials 47 are internally provided, in addition to the bottom surface 27 of the bottomed substantially rectangular container 23, two ones facing each other in one direction are additionally provided. Provided on the outside of at least one kind of surface selected from one of the surfaces and two surfaces facing each other in the other direction, as a fixing means capable of being attached to and detached from the bathtub. This is the seventh bathtub partitioning tool. Similar to the example shown in FIGS. 9 to 11, this example is also foldable in the direction of the arrow in the figure, but is different in that folds are not formed in advance. In this example, as the surface, the back surface 29 on the end surface side of the existing bathtub 9 is one of the two surfaces facing each other in one direction, and the two surfaces facing each other in the other direction. Side surfaces 25, 25 and bottom surface 27
Are provided at four locations. And, in particular, the attachment positions of the suction cups 19 ...
In the portion where is enclosed, the force of the shape-retaining core material 47 ... Is difficult to act to separate the suction cups 19 ... from the inner surface of the existing bathtub 9, and more stable suction fixation can be realized. Further, similarly to the above, other fixing means can be used in addition to the suction cups 19 ... In this case, the sixth bathtub partitioning tool is used. Similarly to the above, as shown by the phantom line in the figure, it is convenient to supply and drain water when a stopper 33 is provided near the bottom of the bottomed substantially rectangular container 23 and is sealed after the completion of water injection. As for the internal form of the shape-retaining core material 47, the flexible material forming the bottomed substantially rectangular container 23 has a double structure of an inner layer 49 and an outer layer 51 as shown in FIG. A sandwiching structure or the like can be exemplified. Further, by additionally providing shape retaining plates 41, 41 shown by imaginary lines in the figure on the two side surfaces 29, 31 facing each other in one direction, an eighth bathtub partitioning tool 37 is obtained. The shape retaining plates 41, 41 may have a double structure as shown in FIGS. 9 to 11.

As the material used for the sheet-shaped partition member 7 and the bottomed substantially rectangular container 23 of such a bathtub partitioning tool, a normal synthetic rubber sheet or the like can be used as described above, and a synthetic rubber foam sheet. , A polyurethane foam sheet, a PVC plastic film, and a laminate with each synthetic fiber cloth (coated fabric, synthetic leather, etc.) can be used. The material used for the diving suit is suitable for obtaining a good feel, and will be described in detail below.

That is, the flexible material used in the first to eighth bathtub dividers is a laminate of synthetic fiber cloth and synthetic rubber foam, which is an example of the material used in diving suits. As a result, it becomes a ninth bathtub partitioning tool. As shown in FIG. 14, the structure of this laminate is 2
As a structure in which a synthetic rubber foam 55 is sandwiched between two synthetic fiber cloths 53, 53 or a structure for enhancing the water-blocking function,
As shown in FIG. 15, an example in which synthetic fiber cloth 53 / waterproof sheet 57 of aluminum, synthetic resin, etc./synthetic fiber cloth 53 / synthetic rubber foam 55 / synthetic fiber cloth 53 are sequentially laminated can be exemplified.

The bathtub partitioning tool as described above is used to form the two-tank bathtub of the present invention. That is, as shown in FIG. 4, when any one of the above-described first to ninth bathtub partitioning tools is mounted on the inner surface of the bathtub, a two-tub bathtub can be constructed.

[0023]

As described above in the section of the operation, according to the present invention, the following excellent effects can be obtained. First of all, in the first bathtub partitioning tool, a two-tank bathtub can be obtained only by mounting the bathtub partitioning tool on the inner surface of the bathtub using the fixing means, and the opening portion of the substantially rectangular frame body with the central portion opened Since the sheet-shaped partition member made of a flexible material having water impermeability is attached, the limbs of the bather are hit and stretched, so that the user can enjoy a comfortable and comfortable bath without feeling cramped. In addition, by forming a flexible material having water impermeability into a substantially hemispherical shape so that the concave portion formed by the hemispherical portion can be inverted, the other side becomes a convex portion when entering one bathtub. Can be used more widely. Also, when entering the other bathtub, it is possible to make the bathtub widely used because it can be made into a concave state by reversing this convex portion. In the second bathtub partitioning tool, a bottomed substantially rectangular container made of a water-impervious material is preliminarily mounted in the bathtub when the bathtub is in an empty state, and hot water is again placed in the bathtub and a bottomed substantially rectangular shape. Water can be put into the container at the same time, or water can be put into both at the same time, and only the bathtub side can be boiled to an appropriate hot water temperature by heating from the bath kettle. A bathtub can be constructed. And it is provided on the outside of at least one surface selected from the bottom surface of the bottomed substantially rectangular container, one of the two surfaces facing each other in one direction, and the two surfaces facing each other in the other direction. In addition, since the bottomed substantially rectangular container can be fixed to the inner wall of the bathtub by the fixing means that can be attached to and detached from the bathtub, it will not shift during bathing, and the heating port will be closed during bath heating. Since it will not be lost, it will be highly safe. In the third bathtub divider, since the suction cup is used as the fixing means, the attaching / detaching work becomes easier. In the fourth bathtub divider,
A bottomed rectangular container made of water-impervious material should be installed in the bathtub when the bathtub is empty, and hot water should be placed in the bathtub and water should be placed in the bottomed substantially rectangular container at the same time. Alternatively, since it is possible to boil only the bathtub side to an appropriate hot water temperature by pouring water into both or both at the same time and heating it from the bathtub, it is possible to construct a two-tank bathtub using the existing bathtub very easily. And the bellows-shaped folds on the bottomed rectangular container make it possible to fold the bottomed rectangular container in one direction, so it can be folded compactly when not in use or when you want to enjoy a normal bath with hot water only. There is no wasted space. In the fifth bathtub partitioning tool, a bottomed rectangular container made of a water-blocking material that is accordion-shaped and expandable / contractible in one direction is installed in the bathtub in advance when the bathtub is empty. It is possible to boil only hot water and water in the bottomed rectangular container at the same time, or both at the same time and boil only the bathtub side to an appropriate hot water temperature by heating from the bath kettle. It is possible to construct a two-tank type bath very simply by using. And since the shape-retaining core material of one or a plurality of pieces, which is installed over the two surfaces and the bottom surface which face each other orthogonally to the expansion / contraction direction of the bottomed rectangular container, exhibits the shape-retaining action of the bottomed rectangular container, Since it is possible to prevent the bottomed rectangular container from being deformed when it is filled with water or when taking a bath, it is possible to prevent water from overflowing to the hot water tank side due to the deformation. In the sixth bathtub partitioning tool, the bottom surface of the bottomed rectangular container in the fourth bathtub partitioning tool or the fifth bathtub partitioning tool, and one of the two surfaces facing each other in one direction, Since the fixing means capable of being attached to and detached from the bathtub is provided on the outside of at least one surface selected from two surfaces facing each other in the other direction, the bottomed substantially rectangular container is adsorbed and fixed to the inner wall of the bathtub. It is possible to avoid slipping while bathing, and while bathing,
Since it does not block the firing port, it is also highly safe. In the seventh bathtub partitioning tool, since the suction cup is used as the fixing means, the attachment / detachment work becomes easier. In the eighth bathtub partitioning tool, the fourth bathtub partitioning tool, the fifth bathtub partitioning tool, the sixth bathtub partitioning tool, or the seventh bathtub partitioning tool is attached to two surfaces facing each other in one direction. The shape-retaining plate plays the shape-retaining function of the bottomed rectangular container, which facilitates the folding operation and prevents the bottomed rectangular container from being deformed when it is filled with water or when taking a bath. It is possible to prevent water from overflowing. In this case, the dimensions of the bottomed rectangular container may be set so that the surface on which the shape retaining plate is not provided is in close contact with the inner surface of the existing bathtub. The ninth bathtub partitioner has a structure in which a synthetic rubber foam is sandwiched between at least two synthetic fiber sheets in the water-blocking material of any of the first to eighth bathtub partitioning tools. Therefore, the effect of preventing the heat from being transferred from the hot water tank side to the cold water bath side is obtained during the bath heating, the bathing, or the waiting for the bathing, and the hot water temperature does not drop or the water temperature does not rise.

In the two-tub type bath using the bathtub partitioning tool of the present invention, the existing bath can be made into a two-tank type, which is excellent in handleability and heat insulation and requires a cramped bathing operation. Moreover, it exerts an excellent effect that does not require useless space. Further, since the bathtub partitioning tool can be attached and detached, the bathtub partitioning tool is provided with functionality so that it can be used as a conventional one-tub type bathtub as needed. In addition, although the above-mentioned embodiment has been mainly described by using the example of the hot and cold bath, a two-tank type bath including ordinary hot water and medicinal water (hot spring), enzyme bath, mud (clay) hot water, etc. You can also enjoy taking a bath.
