Abstract
Description
[Technical Field]
[0001] The present invention relates to an enzyme bathtub comprising a bathtub body containing enzyme bath materials such as sawdust or bran, and a bathtub lid for opening and closing the upper opening of the bathtub body. [Background technology]
[0002] In recent years, enzyme baths that utilize enzymes have been attracting attention. In these enzyme baths, the body is immersed in cypress or cedar sawdust or rice bran placed inside the bathtub, and the body is warmed by the heat generated when the microorganisms contained within the cypress or cedar sawdust or rice bran become activated and ferment. At the same time, the body is exposed to radiation such as far-infrared rays emitted by the activated cypress or cedar sawdust or rice bran, which activates or increases the body's enzymes and enhances the body's natural healing powers.
[0003] To achieve this, it is important to activate the microorganisms contained in the cypress or cedar sawdust or rice bran placed in the bathtub body. Activation is particularly necessary when microbial activity is low, such as at the start of work or during the cold winter months. Conventionally, activation has been achieved by manually stirring the cypress or cedar sawdust or rice bran placed in the bathtub body, which requires considerable effort.
[0004] Patent Document 1 listed below proposes an agitation device that agitates and activates cypress or cedar sawdust or rice bran placed in the bathtub body as a measure to reduce manual labor.
[0005] However, even if the labor required was reduced by using an agitator, the work of manually operating the agitator to agitate and activate the cypress or cedar sawdust or rice bran placed in the bathtub body was still not eliminated.
[0006] Furthermore, conventional bathtub covers are often not used, and the bathtub body is left open. Even when a bathtub cover is used, it only serves to cover the upper opening of the bathtub body to prevent heat dissipation, and is not used to activate the cypress or cedar sawdust or rice bran placed in the bathtub body.

[0007] [Patent Document 1] Patent No. 6901808 Summary of the Invention [Problem to be solved by the invention]
[0008] The present invention has been made to solve the above-mentioned problems, and its purpose is to provide an enzyme bathtub that can activate the microorganisms contained inside the enzyme bath materials such as sawdust or bran without stirring the enzyme bath materials such as sawdust or bran placed in the bathtub body. [Means for solving the problem]
[0009] In order to achieve the above-mentioned object, the enzyme bathtub according to claim 1 of the present invention is an enzyme bathtub having a bathtub body containing enzyme bath materials such as sawdust or bran, characterized in that the bathtub body has a water heater installed on the bottom.
[0010] In addition, the enzyme bathtub of claim 2 of the present invention is an enzyme bathtub comprising a bathtub body containing enzyme bath materials such as sawdust or bran, and a bathtub lid that opens and closes the upper opening of the bathtub body, characterized in that the bathtub lid is in the shape of a square plate and has a compound mixture adhesively laminated on the underside, the compound mixture being mainly composed of a diatomaceous earth mixture containing diatomaceous earth as the main component and a natural stone powder mixture containing granite and Beitou stone powder as the main components.
[0011] Furthermore, the enzyme bathtub according to claim 3 of the present invention is the enzyme bathtub according to claim 2, characterized in that the compounded mixture contains 100 parts by weight of the diatomaceous earth mixture and 50 to 70 parts by weight of the natural stone powder mixture, and the proportion of the Beitou stone powder contained in the natural stone powder mixture is 50% by weight or more.
[0012] In addition, the enzyme bathtub of claim 4 of the present invention is an enzyme bathtub comprising a bathtub body containing enzyme bath materials such as sawdust or bran, and a bathtub lid that opens and closes the upper opening of the bathtub body, wherein the bathtub body has a water heater installed on the bottom, and the bathtub lid is in the form of a square plate, and a compound mixture whose main components are a diatomaceous earth mixture containing diatomaceous earth as the main component and a natural stone powder mixture containing granite and Beitou stone powder as the main components is glued and laminated on the underside.
[0013] Furthermore, the enzyme bathtub of claim 5 of the present invention is characterized in that, in the enzyme bathtub of claim 4, the compound mixture contains 50 to 70 parts by weight of the natural stone powder mixture per 100 parts by weight of the diatomaceous earth mixture, and the proportion of the Beitou stone powder contained in the natural stone powder mixture is 50% by weight or more. [Effects of the Invention]
[0014] The enzyme bathtub with the above configuration has a water heater installed on the bottom of the bathtub body, so that the enzyme bath materials such as sawdust or bran placed in the bathtub body can be heated, and temperature control can be performed to activate the fermentation of the microorganisms contained inside the enzyme bath materials such as sawdust or bran.
[0015] Furthermore, the bathtub lid is made of a square plate, and a compound mixture consisting primarily of a diatomaceous earth mixture containing diatomaceous earth as its main component and a natural stone powder mixture containing granite and Beitou stone powder as its main components is glued and laminated to the underside.Therefore, radon generated from the natural stone powder mixture can activate the fermentation of microorganisms contained inside the enzyme bath materials such as sawdust or bran placed in the bathtub body.
[0016] Furthermore, if the blended mixture contains 100 parts by weight of the diatomaceous earth mixture and 50 to 70 parts by weight of the natural stone powder mixture, and the proportion of the Beitou stone powder contained in the natural stone powder mixture is 50% by weight or more, the amount of radon generated from the natural stone powder mixture will be greater, which will further activate the fermentation of the microorganisms contained inside the enzyme bath materials such as sawdust or bran placed in the bathtub body.
[0017] Furthermore, since the compounded mixture adhesively laminated to the bathtub lid contains a diatomaceous earth mixture, it has a humidity-regulating effect and a deodorizing effect that absorbs odors generated from sawdust or bran. [Brief explanation of the drawings]
[0018] [Figure 1] 1 is a perspective view of an enzyme bath tub according to the present invention; FIG. [Figure 2] FIG. 2 is a cross-sectional view of the bathtub body according to the present invention. [Figure 3] 1 is a perspective view of a water heater according to the present invention; DETAILED DESCRIPTION OF THE INVENTION
[0019] The following describes an embodiment of the enzyme bath tub according to the present invention with reference to the drawings. However, the scope of the present invention is not intended to be limited to the content described in this embodiment.
[0020] Figure 1 is an oblique view of the enzyme bathtub of the present invention, with each part separated before assembly; Figure 2 is a vertical cross-sectional view of the bathtub body, which is part of the enzyme bathtub of the present invention; and Figure 3 is an oblique view of the water heater to be installed in the enzyme bathtub of the present invention, with each part separated before assembly.
[0021] As shown in FIG. 1, the enzyme bath tub 1 according to the present invention comprises a bathtub body 10 and a bathtub lid 40.
[0022] As shown in Figure 2, the bathtub body 10 has a bottom plate 12 on the bottom surface 11 surrounded on all four sides by side plates 13, and both the bottom plate 12 and the side plates 13 are made of cedar boards and are shaped like a rectangle with an opening 14 at the top.
[0023] A water heater 20 is installed on the bottom plate 12 of the bottom surface 11. As shown in Figure 3, the water heater 20 is composed of connected resin pipes 21 arranged at regular intervals through which hot water circulates, stainless steel sheets 22 sandwiching the top and bottom of the pipes 21, and a flow regulator 23 that controls the temperature of the sheets 22 by adjusting the flow rate within the pipes. Rice bran 30 is placed on top of this sheet 22. Although the pipes 21 are shown in one layer in Figure 2, they may be stacked in two or three layers with the sheets 22 sandwiched between them.
[0024] The sheet 22 is made of SUS, so it is rust-resistant and has good thermal conductivity, and the heat from the pipe 21 is conducted to the entire surface of the sheet 22, warming the entire surface of the sheet 22 uniformly, so that the rice bran 30 loaded on the sheet 22 can be heated uniformly.
[0025] The bathtub lid 40 is formed from six bathtub lid pieces 41 formed from square cedar boards, and a compounded mixture 50 is glued and laminated to a thickness of about 5 mm between wooden frames 43 on the underside 42 which faces the bathtub body 10 when the bathtub lid 40 is hung on the bathtub body.
[0026] The compounded mixture 50 is a mixture of a diatomaceous earth mixture containing diatomaceous earth as a main component and a powder mixture of natural stone containing granite and beitou stone as main components.
[0027] The diatomaceous earth mixture may contain diatomaceous earth as the main component and a binder, and may further contain an inorganic salt mixture or the like to strengthen the binding of the diatomaceous earth.
[0028] As the binder, any binder that improves the adhesion between the mixed mixtures 50 and between the mixed mixtures 50 and the bathtub lid 40 may be used, such as hydraulic binders such as lime plaster, hydrated lime, and gypsum, as well as water-based urethane resins such as methyl cellulose and vinyl acetate, and mortar emulsion resins such as acrylic emulsion.
[0029] The inorganic salt mixture is an inorganic salt or metal salt containing a large amount of alkali ions or metal ions, such as ammonium salts, sodium salts, potassium salts, magnesium salts, etc.
[0030] The proportion of diatomaceous earth in the diatomaceous earth mixture is preferably at least 60% to 95% by weight, and more preferably 80% to 90% by weight. If the proportion of diatomaceous earth is less than 60% by weight, the humidity-regulating and deodorizing effects of diatomaceous earth are not fully exhibited, and if it exceeds 95% by weight, there is a risk that the binder will be insufficient and that the blended mixture 50, which is adhesively laminated to the bathtub lid 40, will peel off.
[0031] The natural stone powder mixture contains granite and beitouite as main components, and the main components of the granite are quartz and feldspar, but may also contain plagioclase, pyroxene, mica, apatite, magnetite, zircon, garnet, etc.
[0032] The proportion of granite contained in the powder mixture of natural stone is preferably 30% by weight or more, because if the proportion of granite powder is less than 30% by weight, radon will not be generated sufficiently.
[0033] Furthermore, the natural stone powder mixture contains Beitou stone. It is preferable that the proportion of Beitou stone powder contained in the natural stone powder mixture is 50% by weight or more. This is because if the proportion of Beitou stone powder is less than 50% by weight, the radon generation effect of containing Beitou stone cannot be fully obtained. The higher the proportion of Beitou stone, the more effective the radon generation effect will be, but since it is expensive, the proportion must be considered in consideration of costs. The proportion of Beitou stone contained in the natural stone powder mixture is determined in consideration of the total proportion of Beitou stone and granite contained in the natural stone powder mixture.
[0034] The ratio of diatomaceous earth mixture to natural stone powder mixture is 100 parts by weight of diatomaceous earth mixture and 50 to 70 parts by weight of natural stone powder mixture. If the natural stone powder mixture is less than 50 parts by weight, the radon generation effect of mixing the natural stone powder mixture cannot be fully achieved, and if it exceeds 70 parts by weight, the proportion of natural stone becomes too high and the binder effect, humidity control effect, and deodorizing effect of the diatomaceous earth mixture cannot be fully achieved.
[0035] As described above, the enzyme bath tub 1 of the present invention has a water heater 20 installed on the bottom plate 12 of the bottom surface 11 of the bathtub main body 10, making it possible to heat the rice bran 30 on the water heater 20 placed in the bathtub main body 10, and making it possible to control the temperature to activate the fermentation of the microorganisms contained inside the rice bran 30.
[0036] Furthermore, the bathtub lid 40 is made up of six bathtub lid pieces 41 formed from square cedar boards, and the underside 42 of each bathtub lid piece 41 has a blended mixture 50 glued and laminated thereon, the blended mixture 50 being mainly composed of a diatomaceous earth mixture containing diatomaceous earth as its main component and a natural stone powder mixture containing granite and Beitou stone powder as its main components.Therefore, the radon generated from the natural stone powder mixture activates the fermentation of the microorganisms contained inside the rice bran 30 placed in the bathtub body 10, and at the same time, it is possible to exert the so-called radon effect.
[0037] Furthermore, the compound mixture 50 glued and laminated to the underside 42 of each bathtub lid piece 41, which is made of cedar board material, is mainly composed of a diatomaceous earth mixture containing diatomaceous earth as its main component and a natural stone powder mixture containing Beitou stone powder as its main component.If the diatomaceous earth mixture is 100 parts by weight and the natural stone powder mixture is 50 to 70 parts by weight, and the proportion of Beitou stone powder contained in the natural stone powder mixture is 50% by weight or more, the amount of radon generated will increase, making it possible to further activate the fermentation of the microorganisms contained inside the rice bran 30 placed in the bathtub body 10.
[0038] Furthermore, because the bathtub lid 40 is made up of six bathtub lid pieces 41, some of the bathtub lid pieces 41 can be placed over the opening 14 of the bathtub body 10, where the body parts excluding the head are located during bathing, and even while bathing, the radon generated by the blended mixture 50 glued and laminated to the underside 42 of each bathtub lid piece 41 can activate the fermentation of the microorganisms contained within the rice bran 30. This also makes it possible to more efficiently exert the so-called radon effect on the bather.
[0039] Furthermore, since the compounded mixture 50 adhesively laminated on the bathtub lid 40 contains a diatomaceous earth mixture, it is possible to obtain a humidity control effect and a deodorizing effect that absorbs the strong odor generated from the rice bran 30.
[0040] It goes without saying that the enzyme bath tub 1 having the above-mentioned structure can be used not only for humans but also for pets such as dogs and cats.Furthermore, it can also be used as a foot bath. [Explanation of symbols]
