DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying shower system provided in a bathroom or the like and a bathtub pillow used for the system.

[0002]

2. Description of the Related Art In recent years, awareness of health and beauty has increased, and residual chlorine in tap water is not only used for drinking, but also for drinking.
At the time of bathing in a bathroom or washing hair, the hair is damaged or the skin is irritated, and it is noted as a factor of generating a smell of odor. It is desired to remove the residual chlorine. In response to such a demand, a purified water shower system for removing residual chlorine has been sold. Conventionally, as a system that uses purified water as a shower, a water purifier with a water purification function is installed on the floor near the water outlet when connecting a shower head that spouts water in a shower shape and a water supply outlet from which tap water flows out. It was installed and connected so that tap water could flow to the shower head through this water purifier. The water purifier used in this case is generally in the form of various boxes having a side of about 10 to 30 cm. However, the bathroom or the like in which the shower system is provided is generally narrow, and the installation of such a water purifier is extremely inconvenient or inconvenient, and the space use efficiency of the installation place is deteriorated. In order to solve such a problem in installation, a shower head containing a water purification cartridge has been invented. In such a case, since the water purifier is not provided independently in the bathroom, the bathroom can be widely used.

[0003]

However, in such a water purification shower system, the size of the water purification cartridge is limited by the size of the shower head because the water purification cartridge is housed in the shower head. There was also a limitation on the amount of filter material to be filled in the water purification cartridge. For this reason, the amount of the filtering material cannot be increased, so that it has been difficult to improve the filtering performance and extend the life of the water purification cartridge. Similarly, since the cross-sectional area of the water inside the water purification cartridge is also limited, the cross-sectional area cannot be increased significantly. Therefore, it is difficult to reduce the pressure loss and increase the flow rate of the purified water. Was. Also, inside the originally hollow shower head,
Since the water purification cartridge filled with the filtering material is stored, the weight of the shower head becomes heavy, and there is a problem that it is difficult to handle especially for women and children.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can be installed in a space-saving manner, without impairing the space use efficiency of the installation place, improving the water treatment performance, extending the service life, and increasing the flow rate of purified water. It is an object of the present invention to provide a water-purifying shower system with a low showerhead weight, high performance, excellent convenience, and comfort, and a bathtub pillow used therefor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One example of the present invention will be described with reference to the drawings. In the purified water shower system shown in FIG.
On the rims 14, 15 of the bathtub 10, a bathtub pillow 12 according to the invention
Is installed. The bath pillow 12 is simply placed or secured on its rim 14, depending on the mode of use. At the time of fixing, it is fixed with nails or screws, a suction cup, a double-sided tape, an adhesive or the like according to the required physical properties. As shown in FIG. 2, the bathtub pillow 12 has a long tubular body 16 and an elastic member 42 formed around the tubular body 16. Tube 16
Is schematically composed of a cylindrical housing 18 and a lid 20 attached to one end of the housing 18. These housings 18
The material of the lid 20 is not particularly limited, but a material having high strength such as rigidity and pressure resistance and high heat resistance is preferable.
Resins such as BS, polypropylene, vinyl chloride, polystyrene, polysulfone, polyacetal, polycarbonate, and polyphenylene ether, and metals such as aluminum and stainless steel can be used. The lid 20 must be detachably and watertightly and firmly attached to the housing 18, and a fitting type, a screwing type, or the like can be applied. In the illustrated example of the tube 16, a raw water inlet 22 and a purified water outlet 24 are formed at one end thereof. The raw water inlet 22 is connected to a water supply port to which raw water such as water or hot water is supplied through a pipe or the like buried inside a wall or a bathtub, and the purified water outlet 24 is provided inside the wall or the bathtub. Is connected to the purified water supply port 44 by a pipe buried in the. A shower head 60 that jets clean water in a shower shape has a hose 62.
Is connected to this purified water supply port 44. In the illustrated example, the pipes connected to the raw water inlet 22 and the pipes connected to the purified water outlet 24 are respectively buried in the wall, but this is not always necessary. For example, when the bathtub pillow according to the present invention is attached after the bathroom is constructed, it may be connected to each with an exposed hose or the like. In this case, although it is necessary to arrange hoses and the like, there is an advantage that the work can be installed later in the existing bathroom without any need for construction or the like.

The water purification cartridges 26, 26,... As shown in FIG. 4, the water purification cartridge 26 has a substantially columnar shape. A convex water passage 28 is formed at a convex portion 27 formed at the distal end, and a concave portion 29 is formed at a concave portion 29 formed at the base end. The water passage 30 is formed, and the convex portion 27 of one water purification cartridge 26 is formed.
And the recess 29 of the other water purification cartridge 26 can be fitted to each other. In the illustrated example, each projection 2
A packing 34 is formed on the side surface of 7, so that the connection state at the time of fitting can be ensured and the leakage of purified water can be prevented. The packing 34 is annular, and for example, an elastic material such as nitrile rubber (NBR), styrene butadiene rubber (SBR), silicon rubber, fluorine rubber, chloroprene rubber, ethylene propylene rubber, and butyl rubber can be applied. The convex water passage 28 and the concave water passage 30 communicate with each other via a water pipe 32 penetrating the center of the water purification cartridge 26. The water pipe 32 is a tubular body made of the above-described resin, metal, or the like, and has a large number of fine holes. With such a configuration, a plurality of water purification cartridges can be connected without requiring a special connection member, and replacement of the water purification cartridge is easy.

The water treatment material 36 filled in the water purification cartridge 26 includes calcium sulfite, granular activated carbon, fibrous activated carbon, a dechlorinating agent such as ascorbic acid (vitamin C), a porous hollow fiber membrane, ion An exchange resin or the like is used. These may be used alone or in combination of two or more. When the main purpose is to remove residual chlorine in raw water, it is preferable to use a dechlorination treatment agent, and among them, calcium sulfite excellent in dechlorination ability is suitably used. When the purpose is to remove turbid components in raw water, it is preferable to use a porous hollow fiber membrane that can remove bacteria. The water treatment material 36 is not particularly limited as long as the water treatment material 36 can be retained in the water treatment cartridge 26 as long as the water treatment material can exhibit a water purification function.
If 6 is a film, it may be wound around the water pipe 32. When the water treatment material 36 is granular or powdery, such as granular activated carbon, it may be provided in the water purification cartridge 26 by putting it in a bag made of nonwoven fabric or the like. Alternatively, the water treatment material may be solidified together with a binder or the like and formed directly around the water flow pipe 32. These water treatment materials 36
The outer peripheral portion may be provided with a water permeable case or may be exposed as long as the water treatment material does not flow out.

In the illustrated example, the water purification cartridge 26
Are contained in the pipe 16, but this is not always necessary, and one water purification cartridge having a length substantially equal to the length of the pipe 16 is provided in one pipe 16. It may be accommodated. However, by using a plurality of water purification cartridges, it is possible to use an arbitrary number of water purification cartridges according to the target performance, and it is easy to extend the life. Furthermore, by connecting and accommodating a plurality of short water purification cartridges 26, the water purification function as a whole can be reduced without impairing the overall water purification function.
Since the water purifying cartridge can be easily replaced by reducing the size of the water purifying cartridge per unit, it is desirable that a plurality of water purifying cartridges 26 be connected and accommodated in the tube 16. Furthermore, by using a plurality of water purification cartridges, different types of water purification cartridges can be used in combination, and a combined effect can be generated according to, for example, the state of raw water. For example, when the purpose is to remove residual chlorine and heavy metal ions in raw water, by using a water purification cartridge filled with a dechlorination agent as a water treatment material and a water purification cartridge filled with an ion exchange resin, A water purification function having both functions can be exhibited. Note that all of the plurality of water purification cartridges do not necessarily have to have the same shape, but by making them the same shape, the production cost of a mold and the like can be reduced.

To accommodate the water purification cartridge 26 inside the tube 16, the lid 20 is opened, and, for example, to accommodate three water purification cartridges 26, the first water purification cartridge 26 is placed at the base end thereof. It is pushed in from the side so that the concave portion 29 fits into the annular internal protrusion 38 formed in the innermost portion of the housing 18. Next, the second water purification cartridge 2
6 is pushed in in the same manner, and the concave portion 29 is fitted to the convex portion 27 of the first water purification cartridge 26. further,
The third water purification cartridge 26 is pushed into the housing 18, and the concave portion 29 is fitted to the projection 27 of the second water purification cartridge 26. After that, the lid 20 is attached to the housing 18. At this time, the annular projection 40 formed inside the lid 20 and the projection 2 of the third water purification cartridge 26 are formed.
7 and the three water purification cartridges 26,
26, 26 are fixed and accommodated inside the pipe 18, with the respective water pipes 32 communicating therewith. Water purification cartridge 26
The replacement can be easily performed by removing the lid 20. Furthermore, in the above-described example, the convex portions 27 and the concave portions 29 of the plurality of water purification cartridges 26 are fitted with each other and sealed with the packing 34. May be connected. In this case, when removing the water purification cartridge from the inside of the tube 16 and replacing it, simply pull out the water purification cartridge disposed near the lid 20 to be removed, and simultaneously connect the plurality of water purification cartridges connected thereto. It can be pulled out, making the replacement of the water purification cartridge easier.

In the pipe 16, a raw water inlet 22
Raw water such as water or hot water supplied from the water enters into each of the water purification cartridges 26 from the side thereof, is filtered by the water treatment material 36, and then the purified water enters into the water pipe 32, and flows through the water pipe 32. The water is sent to the purified water outlet 24 of the pipe 16.
In the tube 16 of the illustrated example, at one end, the raw water inlet 22 is formed on the side surface of the housing 18, and the purified water outlet 24 is formed on the end surface of the housing 18, and the raw water enters from the side of the water purification cartridge 26, The purified water is discharged through the central water pipe 32, but is not limited to this. For example, a raw water inlet portion is formed on an end face of the housing 18, a purified water outlet portion is formed on a side surface of the housing 18, and the raw water is supplied to the water treatment material 36 via the water pipe 32 of the water purification cartridge 26.
Water from the center side, and the purified water is
The water may be discharged from the purified water discharge section so as to be discharged from the side surface of No. 6. Also, the raw water inlet and the purified water outlet can be formed on the same end surface of the housing 18. Further, as shown in FIG. 3, a purified water outlet 25 is formed in the lid 21, the raw water is supplied from the raw water inlet 22 to the inside of the pipe 17, and formed at an end different from the raw water inlet 22. It is also possible to discharge purified water from the purified water outlet 25.

Further, the pipe body may be provided with a bypass for connecting the raw water inlet section and the purified water outlet section without passing through the water treatment material, and a switching mechanism for controlling the flow of the raw water to the bypass. . With such a structure, the user can operate the switching mechanism to leave the raw water or to switch the purified water out of the shower.
Thus, when clean water is not required, for example, tubs and towels can be washed using raw water from the shower. As described above, by using the purified water only when necessary, the life of the water treatment material can be extended. As the switching mechanism, a well-known general mechanism may be used, and a switching valve of a rotor valve type, a ball valve type, or the like can be applied.

The bathtub pillow 12 has an elastic member 42 formed around the tubular body 16 in order to exhibit the comfort as a pillow. As the elastic member 42, various materials can be applied as long as they exhibit the required hardness (flexibility).
