Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple bath purifier which removes odor of water and residual chlorine in a bath and suppresses generation of trihalomethane.

[0002]

2. Description of the Related Art Most of the water that fills a bathtub is tap water, but tap water contains residual chlorine, and this residual chlorine produces a chlorine odor, and tap water also contains harmful components, mold and ammonia. Etc. are also included, and these contained substances emit an odor. Then, the residual chlorine reacts with the halogen substance to generate trihalomethane, and therefore, trihalomethane may be mixed in the bath water.

Therefore, it is desired to remove the chlorine odor, chlorine, and other odors of water in the bathtub to suppress the generation of trihalomethane.

[0004]

Recently, various purifying devices have been put on the market that can constantly circulate and filter hot water in a bathtub and use the purified hot water to bathe for 24 hours. Such a purifier has a function of removing dirt and suspended matter from hot water and purifying it, but has a poor ability to remove chlorine, residual chlorine, and other odors. In particular, the ability to remove trihalomethane, which is said to be a carcinogen, can hardly be expected. Moreover, since this type of device is equipped with a pump, a filter, etc., its structure is complicated, its price is expensive, and it is difficult to spread it to general households.

It is said that when water is boiled, some of the trihalomethane in the water is evaporated and the trihalomethane is removed from the hot water. However, the trihalomethane does not easily decompose even when it is evaporated, so it remains in the bathroom. There's a problem.

Therefore, an object of the present invention is to remove various odors of water (hot water) in a bathtub, remove residual chlorine and trihalomethane, and provide a simple bathtub purifier which allows a comfortable bathing. It is a thing.

[0007]

According to a first aspect of the present invention, there is provided a water-permeable container attached to a bath; a porous ceramic contained in the container; an activated carbon contained in the container; An antibacterial agent contained in a container, and a purifier for a bathtub.

Here, the term "container having water permeability" means:
The casing includes a casing having a plurality of water passage holes, a wire net or a fiber net bag, and a bag made of water-permeable cloth or non-woven fabric.

As the antibacterial agent, metallic antibacterial agents such as silver, copper and zinc are effective.

According to the first aspect of the invention, when the bath tub purifier is immersed in water (hot water) in the bath, the water enters the container, and the water comes into contact with the porous ceramic, the activated carbon and the antibacterial agent. . Residual chlorine, chlorine, harmful components, odorous components such as mold and ammonia, and various other impurities contained in water are adsorbed on the porous ceramic and activated carbon by the adsorption action of the porous ceramic and activated carbon. Then, the antibacterial agent sterilizes or sterilizes harmful components by the bactericidal action, and prevents the propagation of various bacteria. Therefore, various odors of water in the bathtub can be removed, residual chlorine and trihalomethane can be removed, and a comfortable bath can be performed. Further, minerals are eluted from the porous ceramic, which is effective for skin health.

The invention of claim 2 is characterized in that the porous ceramic is a large number of particles, and activated carbon and a metallic antibacterial agent are mixed in each porous ceramic particle. This is a bathtub purifier.

According to the second aspect of the present invention, since the activated carbon and the metallic antibacterial agent are integrally held in the porous ceramic particles, the handling is easier than in the case where these substances are individually contained in the container. is there.

According to a third aspect of the invention, the porous ceramic particles are mainly composed of silicon oxide and aluminum oxide, and other oxides of at least alkali metal and alkaline earth metal are mixed in an amount of 5% by weight or more and 30% by weight or less. The activated carbon is mixed in a ratio of 10% by weight or more and 65% by weight or less with respect to the whole, and the metallic antibacterial agent is
3. The bath purifier according to claim 2, wherein the mixture is mixed in a proportion of 0.1% by weight or more and 5% by weight or less with respect to the whole.

According to the invention of claim 3, the composition of the porous ceramic particles contains at least 5% by weight and 30% by weight or less of oxides of alkali metal and alkaline earth metal. The alkaline earth metal ionically bonds with halogen to decompose trihalomethane and reduce the precipitation of trihalomethane. That is, alkali metals such as Na and K and alkaline earth metals such as Ca are likely to form ionic bonds with halogens such as chlorine Cl and bromine Br, so that Cl and Br in trihalomethane are associated with Na, K and Ca. Become. Therefore, the precipitation of trihalomethane is reduced. When the mixing ratio of the oxide of an alkali metal and the oxide of an alkaline earth metal is less than 5% by weight, the adsorbing action of trihalomethane is small and the effect is low. Therefore, it is necessary to mix 5% by weight or more. On the other hand, if it exceeds 35% by weight, the amount of silica and alumina, which are the main components of the porous ceramic structure, decreases, and the ceramic strength decreases.

The activated carbon is 10% by weight based on the whole.
As mentioned above, since it is mixed at a ratio of 65% by weight or less, not only the activated carbon adsorbs residual chlorine, but also pesticides, viruses, detergents, musty odors, chlorine odors and other odorous components contained in water, iron It captures and filters heavy metals such as copper, zinc, lead, and manganese well. If the amount of activated carbon is less than 10% by weight based on the whole, the adsorption performance of the above substances cannot be expected, and if the amount of activated carbon exceeds 65% by weight based on the whole, the strength of the ceramic decreases.

Further, the metallic antibacterial agent may be any of silver, copper and zinc, but silver is preferable, and 0.1 to the whole is used.
Since they are mixed in a ratio of not less than 5% by weight and not more than 5% by weight, it is possible to prevent bacteria from propagating from substances adsorbed in the pores of the porous ceramic and activated carbon. If the metal-based antibacterial agent is less than 0.1% by weight based on the whole, the bactericidal, sterilizing and sterilizing effects are lowered, and it does not function as an antibacterial metal. I am worried.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on an embodiment shown in the drawings. FIG. 4 shows a state where the bathtub purifier 1 of the present invention is attached to the bathtub 100. The purifier 1 is attached to the inner wall surface of the bathtub 100 via the suction cup 6 shown in FIG. ing.

The purifier 1 has the structure shown in FIGS. That is, 2 is a casing corresponding to the container of the present invention, and this casing 2 is formed of a casing body 3 and a cover 4. Casing body 3
And the cover 4 are each made of synthetic resin,
The mating surfaces are joined together by means such as locking claws or adhesive. The casing body 3 forms a shallow container having an open front surface, and the cover 4 has, for example, a shell shape in consideration of the design, and covers the front opening of the casing body 3. A large number of water holes 5 are formed in the peripheral wall of the casing body 3 at intervals in the circumferential direction,
Water can enter and leave the casing 2 through these water holes 5.

As shown in FIG. 2, the suction cup 6 made of rubber, synthetic rubber or the like is detachably attached to the back surface of the casing 2. Therefore, by adhering the suction cup 6 to the inner surface of the bath 100, the purifier 1 is installed in the bath 1.
The inner surface of 00 can be removably attached.

The casing 2 contains a porous ceramic, activated carbon and an antibacterial agent. These porous ceramics, activated carbon and antibacterial agent may be housed individually in the casing 2, but in the present embodiment, a large number of porous ceramic particles are respectively loaded with activated carbon and a metallic antibacterial agent. Is configured. That is, 10 ... Are particles of porous ceramics, and as shown in FIG. 3, have a spherical shape with a diameter of several mm to several tens of mm. Activated carbon particles 11 and silver particles 12 as a metal-based antibacterial agent are mixed in such porous ceramic particles 10.

The porous ceramic particles 10 are made of silicon oxide Si.
O ₂ and aluminum oxide Al ₂ O ₃ as main components,
In addition, at least 5% by weight or more and 30% by weight or less of oxides of alkali metals and alkaline earth metals are mixed. Sodium oxide Na ₂ O and potassium oxide K ₂ O are effective as the alkali metal oxide, and calcium oxide CaO is suitable as the alkaline earth metal oxide. The activated carbon 11 is mixed with such a porous ceramic at a ratio of 10% by weight or more and 65% by weight or less with respect to the whole. The activated carbon 11 may be coconut shell activated carbon, and has a porous structure in which a large number of pores are formed in the traces of the water that is lost when the water contained in the coconut shell fiber is scattered. Is. In this example, the porosity is 30 to 7
Activated carbon powder having 0% and a specific surface area in the range of 800 to 1500 m ² / g is used, and has very excellent adsorptivity.

As the metal type antibacterial agent 12, silver, copper, zinc or the like can be used.
It is mixed at a ratio of 1% by weight or more and 5% by weight or less.
Note that silver is silver nitrate.

Activated carbon 11 is used as a raw material for the above ceramic components.
And silver 12 are mixed in the above mixing ratio, and water, frog clay and frit glass are mixed and kneaded into a clay shape, which is then molded into a predetermined shape and baked in a baking furnace. In the ceramic molded product manufactured in this manner, the water used when mixed is scattered and removed by the firing step, and pores, that is, voids of continuous pores are formed between the ceramic composition products.

The porous ceramic 10 having such a structure ...
Are accommodated in the casing 2 in a predetermined number. In this case, a large number of porous ceramics 10 are housed in a net bag 7 made of non-water-soluble non-water-soluble material so as not to spill out of the casing 2 if the casing body 3 and the cover 4 should come off. In this state, it is housed in the casing 2.

Further, since the above-mentioned porous ceramics 10 ... Hold the activated carbon 11, when the porous ceramics 10 ... Rub against each other during transportation, there is a concern that the activated carbon may generate powder due to friction. Activated carbon powder may pollute the casing 2. For this reason, it is desirable to put the porous ceramics 10 in the water-soluble bag 8 and then store it in the mesh bag 7 in this state. The water-soluble bag 8 is made of, for example, a sealing material made of polyvinyl alcohol (PVA) or the like, and has a property of being dissolved by being immersed in water for several minutes.

How to use the bathtub purifier 1 thus constructed will be described. As described above, in the novel bathtub purifier 1, the porous ceramics 10 ...
Since it is stored in the casing 2 in the state of being put in,
Before use, the purifier 1 remains immersed in the casing 2 for a few minutes. As a result, the water-soluble bag 8 melts and disappears, and the porous ceramics 10 ... Are held in the casing 2 while being accommodated in the net bag 7. The purifier 1 is suction-fixed to the inner surface of the bath 100 through the suction cup 6.

In this state, water is poured into the bathtub. When immersed in water in the purifier 1, the water passage hole 5 formed by the casing 2
From the water enters the casing 2. Therefore, water contacts the porous ceramics 10 ...

According to such a bath purifier 1, when water that has entered through the water passage holes 5 of the casing 2 touches the porous ceramics 10, the porous ceramics 10 ... Since it has voids, impurities contained in tap water, such as toxic substances, microorganisms, molds,
Adsorbs contaminants such as viruses, pesticides, and heavy metals. In addition, the activated carbon mixed with the porous ceramic structure 1
Since 1 originally has fine continuous pores, this activated carbon 11 also exhibits an excellent adsorption action.

As a result, pollutants such as toxic substances, microorganisms, molds, viruses, pesticides and heavy metals contained in tap water are adsorbed on the porous ceramics 10 ... And the activated carbon 11. Therefore, the water is purified. In addition, the musty odor and the odor of chlorine are removed.

It is said that the activated carbon 11 cannot adsorb ammonia. However, since the porous ceramics 10 adsorb ammonia, the reaction between chlorine and ammonia is suppressed, and the generation of chlorine odor is effectively prevented. be able to.

Further, the porous ceramic 10 has a function of removing trihalomethane and residual chlorine. Trihalomethane can be removed to some extent with activated carbon, but the ability to remove trihalomethane with activated carbon is not sufficient. However, the porous ceramics of this composition ratio are excellent in trihalomethane adsorption performance. This is because the composition of the porous ceramic 11 contains an oxide of an alkali metal such as Na or K and an oxide of an alkaline earth metal such as Ca in an amount of 5% by weight or more and 35% by weight or less. Alkali metals and alkaline earth metals are substances that easily ionically bond with halogens (such as Cl and Br) in trihalomethanes. Therefore, due to these ionic bonds, halogens in trihalomethanes are separated, trihalomethanes are decomposed, and trihalomethanes are reduced. It is presumed that it will be done.

When the mixing ratio of the oxide of alkali metal and the oxide of alkaline earth metal is less than 5% by weight, the adsorbing action of trihalomethane is small and the effect is low. Therefore, it is necessary to mix 5% by weight or more. On the other hand, if it exceeds 35% by weight, the silica and alumina, which are the main components of the porous ceramic structure, are reduced and the ceramic strength is lowered.

Furthermore, since the porous ceramic 10 is mixed with silver 12 as a metallic antibacterial agent, this silver is combined with halogen to form silver halide, which is also considered to reduce trihalomethane. .

The silver 12 has a sterilizing, sterilizing and sterilizing effect, and is contained in the voids of the porous ceramic structure and in the activated carbon 1.
(1) Prevents bacteria from growing from the substance adsorbed in the pores of No. 1. In this case, silver 12 is 0.1% by weight of the whole.
If it is less than 5%, the sterilization, sterilization and sterilization effects are low, and it does not serve as an antibacterial agent. If it exceeds 5% by weight, elution may occur.

From the above, various odors of water in the bathtub are removed, residual chlorine and trihalomethane are removed, and minerals of the composition are eluted from the porous ceramic 10 to promote skin health. , You can take a comfortable bath.

In particular, since the trihalomethane is decomposed in the porous ceramic 10, the trihalomethane is not released into the air in the bathroom, and the intake of steam prevents the trihalomethane from being absorbed by the human body. .

Since the purifier 1 has a function of decomposing trihalomethane, it is preferable that the porous ceramic 10 adsorbs trihalomethane before the trihalomethane is evaporated in the bathroom. It is better to soak in the bath when in water rather than in water.
