2. Description of the Related Art In a general domestic bathtub, a water heater is connected to the bathtub,
Every time heating is required, hot water is supplied by operating a water heater by burning gas. In recent years, there has been an example in which a device that constantly maintains the temperature of hot water in the bath is used, but in any type of water heater, it is placed outside the bathtub using oil or gas or an electric heater. It is configured to supply hot water from a water heater.

However, as described above, the method of arranging the water heater outside the bathtub and heating it as necessary has relatively poor thermal efficiency, and it is not as efficient as the energy used. However, there is a drawback that heating efficiency of hot water is not good. Further, when the water heater is arranged outside the bathtub, the size of the bathtub may be limited due to the large area occupied by the water heater. On the other hand, when the water heater is arranged outside the bathroom, a long pipe is arranged between the water heater and the bathtub, which causes a problem that the heat efficiency of the water heater further decreases.

In order to solve the above problems,
It is practiced to arrange a small heating device called a 24-hour bath near the bath to constantly heat the bath. In addition, a device called a 24-hour bath, which has been widely used in recent years, does not use a bathtub by circulating foreign water in the bathtub with a water heater and removing foreign matters contained in the hot water through a filter or the like. I try to keep the hot water from getting dirty. However, the water heater as described above,
Since a pump or the like is used to circulate the hot water in the bathtub with the water heater, the energy use efficiency is not significantly improved compared to the conventional water heater.

The present invention solves the above-mentioned problems of the conventional water heater. In the state where the heating device is placed in the bathtub, the hot water is circulated in the heating device to heat the heating device. An object of the present invention is to provide a bathtub heating device that can easily purify and heat hot water while releasing effective components such as hot springs from the contained ceramic components.

And a connecting pipe that constitutes one hot water passage, a heater device that is embedded in the main body of the apparatus and whose heating temperature is adjusted by control means, and a ceramic member that is housed in the heating pipeline. Then, the heating device body is heated by the heater device, and the hot water heated through the heating conduit is purified through the ceramic member. Further, in the invention of claim 2 of the present invention, a side lid member is arranged on a side portion of the heating device main body, and a connecting pipe and a heater for connecting a heating pipeline to the inside of the side lid member. A connection line for the members and a filter member for purifying hot water are housed and provided. In the invention of claim 3 of the present invention, the ceramic member housed in the heating conduit of the heating device main body is a mixture of coral powder, a porous inorganic material such as zeolite, and a magnetic material, which are fired. Formed as a porous mass or tubular member formed by the above, the ceramic member, a microorganism that effectively acts on the purification of hot water, hot spring component,
And a component soluble in water such as a fragrance component.

With the above-described structure, the heating device of the present invention directly heats the main body made of ceramic material or natural stone by the heater, so that all the heat of the heater is put in the bathtub. It can be used for heating hot water, and can perform good heating action. Further, in the heating device of the present invention, far infrared rays generated by heating the ceramics of the main body device and the ceramics material arranged in the heating pipeline can have a good effect on people who are bathing in hot water. Therefore, it is possible to improve the effect of bathing by supplying the hot spring component and other effective components for enhancing the bathing effect to the heated hot water from the ceramic member. Further, in the present invention, since a ceramic lump or a pipe-shaped ceramic member is housed in the heating pipe arranged inside the main body to perform the functions of purifying hot water and supplying the active ingredient, The hot water can always be kept clean. Then, when the sterilizing action is performed by using the means for heating the heating device main body at a high temperature on a regular basis, harmful bacteria that grow in hot water can be treated.

[Example] In the heating device configured as described above,
The ceramic member accommodated in the heating conduit 20 of the main body member 11 is configured as a lump, a pipe, or any other shape. The ceramic member contains, for example, an inorganic and porous material such as zeolite (hereinafter referred to as an inorganic material) and a porous material rich in a calcium component such as coral (hereinafter referred to as a calcareous material) as main components. , Activated carbon and magnetic substance are mixed in a predetermined ratio,
It can be molded as a binding material such as a polysaccharide. When the ceramic member is formed in a block,
It is possible to use a ball-shaped, plate-shaped, or arbitrary-shaped molded body having a maximum diameter of about 3 cm. By heating the basic mass of ceramics molded into the shape as described above, the polysaccharide used as the binding material is burned to form more voids inside the mass. Further, since the constituents such as inorganic materials, calcareous materials, and activated carbon are made into ceramics in the inside of the lump while leaving the porous characteristics as they are, those having a very large number of minute voids Configured as.

(1) The water treatment ceramics are produced through the following steps a to e. a: Polysaccharides and water are added to powders of an inorganic material and a calcareous material, and activated carbon and a magnetic material are further added and mixed with stirring. b: The mixture is formed into a lump of a certain size by a granulator. c: After molding, a magnetic field is applied to align the magnetic bodies in the mass, and the direction of the N · S magnetic field is set in the mass. d: Sinter the mass at 350 ° C. to burn the polysaccharides and form small voids inside the mass. e: A strong magnetic field is applied to the mass to magnetize it. The mass produced as described above can be shipped as a product of porous ceramics (A). And
The ceramics (A) has a very large number of minute voids inside, and utilizes calcium and trace components exuded from the calcareous material in water to improve the water quality, and chlorine in water, etc. Can be adsorbed and separated.

(2) Further, it is also possible to form the porous ceramics (B) by additionally performing the following treatments f and g on the ceramics (A) product. f: The ceramic mass treated by the above e is immersed in a solution of a nutrient component required for the growth of polysaccharides such as oligosaccharides, organic acids such as malic acid, and microorganisms such as nucleic acids. The ceramic mass is impregnated with the above components. g: A ceramic mass impregnated with the nutritional component is dried to obtain a product.

Since the ceramics (B) product is prepared by impregnating ceramics which has been fired at a low temperature with the active ingredient required for the growth of microorganisms, the water treatment is performed by the action of microorganisms. Can be used when using.
In other words, the nutrient component exuded from the ceramics (B) and the calcium component (ion) effectively act on the growth of the effective microorganisms. Furthermore, by utilizing a large number of minute voids existing inside the ceramic mass,
It can act to adsorb and separate chlorine and the like in water. In addition, it is possible to improve the water quality by utilizing the calcium component and the trace amount component that are exuded from the calcareous material into the water. It can be used.

Since the ceramics (A) and (B) impart a magnetizing action to the magnetic substance, the strength of the magnetic field should be set according to the type of microorganisms used in water treatment. You can Then, by imparting magnetism to the ceramics, a magnetic field can be applied to the treated water to promote the separating action of impurities or contribute to the proliferating action of microorganisms. That is, it is known that in some kinds of microorganisms (for example, photosynthetic bacteria), the proliferative action becomes active under the action of a magnetic field. Therefore, when treating sewage using such microorganisms, it is possible to effectively use the property that ceramics have a magnetic field, and for other microorganisms, the magnetic field also acts effectively. It is said.

In the description of the ceramics of the present invention, zeolite as the inorganic porous component is 780.

The coral will be described as being heated to 350 ° C., but the heating temperature is not limited to a strict temperature as long as it does not lose the properties of the main constituent elements. For example, when the firing temperature is set for zeolite, the firing is performed at a high temperature, and when the purpose is to mainly utilize the calcium component, 350 to 380 ° C.
It is possible to perform a treatment such as sintering at a low temperature.

(3) In the present invention, the ceramic (C) can be manufactured through the treatment steps shown in the following a to h. a: An inorganic material is fired at 780 ° C. to produce a ceramicized inorganic material. b: Polysaccharides and water are added to the powders of the inorganic material and the calcareous material, which are made into ceramics, and activated carbon and a magnetic material are further added and mixed by stirring. c: The mixture is formed into a constant-sized mass by a granulator. d: After molding, a magnetic field is applied to align the magnetic bodies in the mass, and the direction of the N · S magnetic field is set in the mass. e: Sinter the mass at 350 ° C. ...... Burns polysaccharides to form small voids inside the mass. f: A strong magnetic field is applied to the mass to magnetize it. g: The ceramic mass treated in the above step f is immersed in a solution of a nutrient component required for the growth of polysaccharides such as oligosaccharides, organic acids such as malic acid, and microorganisms such as nucleic acids. , Impregnate each of the above components into a ceramic mass. h: A ceramic mass impregnated with the nutritional component is dried to obtain a product.

The ceramic (C) produced as described above is made into a ceramic by previously firing the inorganic material at a high temperature, and then the lump is fired at a low temperature at which the properties of the calcareous material can be maintained. Therefore, in the ceramic (C) obtained by adding the calcareous material and firing, far infrared rays can be generated by the ceramic component produced by firing the inorganic material, and further, the porous property of the inorganic material can be maintained, It is possible to make effective use of the porous properties of the mass produced. Further, the ceramics (C) includes the ceramics (B)
Since it is impregnated with the same useful nutrients as in the case (1), it is possible to use the effect of far infrared rays when water treatment is performed using microorganisms, as compared with the case of the ceramics (B). It is possible to increase the efficiency of water treatment by activating the activity of microorganisms.

(4) When the ceramic member is formed to be particularly suitable for a bath, the following steps a to h are performed.
Ceramics (D) is manufactured through the process of. a: An inorganic material is fired at 780 ° C. to produce a ceramicized inorganic material. b: 20 parts of ceramicized inorganic material, 15 parts of calcareous material, activated carbon, 0.3 parts of magnetic substance, polysaccharides, 5 parts of vermiculite, 20 parts of fumes, 1.5 parts of iron (divalent iron component), oxidation Add 5 parts of calcium, add aqueous hydrogen peroxide and stir mix. c: The mixture is formed into granules of constant size by a granulator. d: The calcium component of the calcareous material is oxidized by leaving it at a constant temperature for 3 to 4 days. e: After being dried, a magnetic field of 3 to 30 Gauss is applied to align the iron in the magnetic field with the magnetic material in the lump, and N is added to the lump.
-Set the direction of the S magnetic field. f: Sinter the mass at 350 ° C. and burn the polysaccharides to form small voids inside the mass. g: The ceramic mass treated with the above-mentioned f is processed into the following polysaccharides such as oligosaccharides, organic acids such as malic acid and kojic acid, nutritional components such as nucleic acid-related substances, ginkgo biloba extract, and hinokitiol components. Each active ingredient is impregnated into a ceramic mass by immersing it in a solution in which a natural component having such antibacterial properties and a trace element component contained in a hot spring are mixed for 24 hours. h: A ceramic mass sufficiently impregnated with each component contained in the solution is dried to obtain a product.

In the ceramic (D) produced as described above, an inorganic material such as zeolite or vermiculite is made into a ceramic while leaving the porous property, and after mixing other components, a calcareous material is prepared. Since the low temperature firing is carried out at a temperature at which the property of (1) does not change, each mixed component can be effectively used. In addition, by mixing with hydrogen peroxide water before manufacturing the lump, the calcium component can be dissolved in water so that the calcium component can be easily eluted and the bath is rich in calcium ions. It can exert the synergistic effect of magnetism and far infrared rays on water. In addition, the hot spring components, acids, sugars, calcium components, and trace amounts of metal or non-metal components contained in the inorganic material that are impregnated after firing elute little by little over a long period of time. Can maintain and enhance the bathing effect. Then, the calcium component, far infrared rays, and a trace amount component act to improve the property of water, so that the water quality of the bath can be maintained in good condition.

In the ceramic (D), the chitinous component can be mixed in the solution used in the manufacturing step g, and the characteristics of the chitinous substance can be applied to the bath.

Furthermore, the solution to be impregnated in the baked product can be used alone or in the form of a compound by mixing the elements contained in the hot spring component,
Ceramics (D) by adding ingredients specific to your favorite hot spring
By including it in the lump, it is possible to feel like a hot spring without using a bath agent such as powder. In addition to each of the components to be contained, in the present invention, zeolite, vermiculite is used as the inorganic porous material, and coral sand powder or a shell fossil powder can be used as the porous material rich in calcium component. .

In addition to the above structure, it is possible to use fine powder of strontium ferrite magnet as the magnetic material, and the conditions such as the strength of the magnetic field applied to the magnetic material can be set arbitrarily. In addition, each component to be mixed with the ceramics may be replaced with another component having the same property. Further, the ceramics for water treatment of the present invention can be configured as a pipe shape, a ball shape, a flat or medium circular mass, or any other shape, but when used for purifying water in a bath Is preferably configured such that the maximum size thereof is about ½ of the diameter of the heating pipeline.
