In addition, a first coupling hole 13 for coupling the sterilization installation unit 20 is formed at an outer side of the through groove 11, and the first coupling hole 13 is formed at the front and rear surfaces of the door 10. Although it may be formed to penetrate through, it is preferable to be formed on the rear of the door 10 for a neat design so that it is not visible from the front of the door.

Second, the sterilization installation portion 20 is inserted into the through groove 11 from the rear of the door 10 to protrude toward the front of the door 10, inserted into the through groove 11 to the front of the door 10. The protruding insertion portion 21, and through the coupling means 23, such as bolts, characterized in that the close contact portion 27 is configured to be in close contact with the back of the door (10).

In addition, a second coupling hole 25 for coupling the coupling means 23 is formed in the close contact portion 27, and the second coupling hole 25 corresponds to the first coupling hole 13. Is formed. Therefore, the sterilization installation part 20 is fixed to the door 10 by the coupling means 23 coupled to the first and second coupling holes 13 and 25.

In addition, the front surface of the insertion portion 210 is opened to form a space portion 22 in the interior of the insertion portion 21, the toothbrush mounting bracket 21a for mounting the toothbrush 28 in the space portion 21a. ) And an ultraviolet sterilizer 21b for disinfecting the toothbrush 28 mounted on the toothbrush holder 21a, and the battery unit 21c for the operation of the ultraviolet sterilizer 21b is provided.

The "support" represented in Table 1 refers to the penetration of a substance such as ions or a catalyst into a substance, in the present invention, to include ions such as anions and copper ions in the inorganic antibacterial material of the present invention. I use it. The ion exchange of such inorganic oxides is a known phenomenon for a long time. Since the inorganic antimicrobial agent produced by ion exchange of silver and copper ions forms a three-dimensional skeleton structure with fine pores, the specific surface area is large and heat resistance is high. great.

Here, the zeolite having a deodorizing function as a main carrier of the inorganic antibacterial agent in the present invention has aluminosilicate crystals as a basic structure.

Natural zeolites were first discovered in 1756 by Swedish mineralogist Baron-Crons. The origin of zeolite is called Zeolite = Zeo (Boil) + lithos (stone), which means boiling stone in the phenomenon of zeolite boiling in water. Synthetic zeolites were produced in late 1940-when Union Carbide was founded.

The structure of zeolite has the following empirical formula, and as the actual three-dimensional structure, AlO ₄ , SiO ₄ forms tetrahedral structure (Tetrahedra) and is connected to each other while sharing oxygen ions.

Empirical equation _{1: M2 / nO · Al 2} O 3 · ySiO 2 · wH 2 O

         y = 2 to 10

         M: cation

n: Cation valence (e.g., n = 1 for Na, so M2 / nO becomes Na ₂ O).

Zeolite Type Kinds 3A type 4A type 5A type 13X type Cation K Na Ca Na Shared oxygen number 8 8 8 12 Pore size
Pore Size 3 4 5 13

As described above, the zeolite has aluminosilicate crystals as a basic structure, and the fine pores are defined by crystal lattice, and the pores are very uniform in size. The uniform micropores of zeolite can be used to selectively adsorb molecules. This is called the molecular sieve effect. Industrially used molecular sieves include A type with fine pores of 3Å, 4Å, 5Å and X, Y type with larger pores as shown in [Table 2].

Anhydrous zeolites have strong adsorptive properties to polar molecules.

The zeolite used in the present invention is Na-4A type exhibiting strong adsorption characteristics, use a particle size of 150 ~ 500mesh, more preferably 325mesh.

In the case of 4A-type zeolite, the chemical formula is Na ₁₂ · [(AlO ₂ ) _{12 ·} (SiO ₂ ) ₁₂ · XH ₂ O. When the zeolite is anhydrous by heating, 4.5H ₂ O is released and the zeolite skeleton is empty. The zeolites produced and retained can absorb up to about 22% of water, in theory, upon contact with air (hydration).

Unlike commercially available absorbents such as silica gel and activated alumina, the zeolite has a very uniform pore distribution, which enables selective adsorption to molecules of a specific size, and in particular, exhibits excellent selective absorption ability against water molecules.

The high equilibrium absorption of these zeolites is widely applied in most moisture adsorption applications requiring dew point below -60 ° C.

In addition, since the zeolite exhibits relatively excellent absorption at low relative humidity and high temperature compared to other drying / absorption systems, and has a structure mainly composed of Si and Al, the zeolite has excellent absorption at high temperatures and is also relatively high. It is very suitable for the environment where there is a big change of humidity in the season, such as in Korea, because there is little change of absorption capacity according to the change of humidity.

Generally, the pore size is 4.2 Po for the 4A type zeolite.

However, as in the structure of the zeolite described above, the pore size of the zeolite is determined by the number of oxygen shared by the degree of substitution of the cation and the ratio of Al / Si.

The zeolite used in the inorganic antimicrobial agent of the present invention is mixed with 57.5 to 59.5% by weight, but if it is made below the threshold, the deodorization rate is significantly lowered when the deodorization experiment occurs, and when the threshold is exceeded, the viscosity increases and the workability Not only is this reduced, the application of additional components such as activated diatomaceous earth, silver ions and copper ions becomes difficult.

Next, the activated diatomaceous earth used as a carrier of the inorganic antimicrobial agent in the present invention is a mineral composition, and the siliceous siliceous (규) of diatom, which is a single cell algae, is formed as a deposit formed on the sea or lake bottom 90% or more. It is made of amorphous silica (SiO ₂ ), which is a physicochemically stable inorganic material, has numerous small pores on the surface, and maximizes the surface area so that it is light, hygroscopic and heat insulating, and can be applied as a plastic heat insulating material. In addition, diatomaceous earth can play a role of adsorption and filtration of harmful substances in the air to filter out impurities in the indoor air, and deeply stimulate the metabolism of the human body by acting deep inside the body by the release of negative ions and far infrared rays.

In particular, the anion adsorbs and neutralizes cations in the surroundings, which are rapidly increased due to various contaminations. The large pore structure of diatomaceous earth absorbs moisture when it is humid and diverges when it is dry, so that the person repeatedly sleeps and absorbs moisture while sleeping, and gets a good night's sleep. It absorbs substances and protects the human body from harmful electromagnetic waves.

The activated diatomaceous earth in the present invention may be used between 150 and 500 mesh, more preferably using a product of 325 mesh.

In this case, when the active diatomaceous earth is less than 150mesh product, the tissue is not dense and at the same time, the surface is not formed smoothly, and the surface is not formed smoothly. The overall viscosity becomes so high that processing is not easy.

In particular, the activated diatomaceous earth used in the inorganic antimicrobial agent in the present invention is to mix 38 to 40% by weight, if less than the threshold, that is, when the activated structure is mixed to less than 38% by weight absorbs the electromagnetic waves and various contaminants as described above. It is not possible to expect a function that can be, if the threshold is exceeded, that is, when the activated structure is more than 40% by weight, the viscosity is too high, and it is difficult to apply more minerals other than activated diatomaceous earth.

On the other hand, the present invention can be used to prepare a multifunctional synthetic resin using the above-mentioned inorganic antibacterial powder.

Looking at the manufacturing method, various thermoplastic synthetic resins such as ABS resin, SAN resin, nylon resin, polyester resin, polycarbonate (PET, etc.) resin, acrylic resin, diene-based (polybutadiene, etc.) resin or formed by mixing two or more thereof 78 to 82% by weight of a composite resin (Polymer-alloy or Polymer-matrix) is added to a flask that can be heated and stirred to melt and liquefy. 10 to 15% by weight of raw ore is divided into five portions for 30 minutes and then 60 to After stirring sufficiently to disperse for 120 minutes, 5 to 10% by weight of the above-mentioned inorganic antimicrobial agent in powder form is divided into five times for 30 minutes, and then stirred for 60 to 120 minutes, and then into a plate or pallet. It can be manufactured by cold forming.

The thermoplastic resin or composite resin is used by mixing 78 to 82% by weight depending on the component, when formed below the threshold value, the intrinsic function of the thermoplastic resin or composite resin is lost, if the threshold value is exceeded other components The amount of these mixtures decreases, making it difficult to express additional functions other than the basic characteristics of the resin.

Next, the inorganic antimicrobial agent in powder form is mixed with 5 to 10% by weight, and more preferably, 7 to 8% by weight is mixed.

The inorganic antimicrobial agent is to impart antimicrobial function and deodorization function to the thermoplastic resin or composite resin, and when mixed below a threshold value, it becomes difficult to express antibacterial and deodorant function, and when the threshold value is exceeded, a high viscosity forms a uniform Not only is it difficult to distribute, but also raises the price.

Next, bio ore is a biotite-based 4 ~ 16㎛ far-infrared ray with biological cell activation effect revealed by NASA at 25 ℃, which is a temperature lower than 35-40 ℃ which is the temperature for measuring the far-infrared emissivity. It is a substance that emits wavelengths. In particular, it is a substance that strongly radiates far-infrared wavelengths in the 8 to 12-micrometer range centering on far-infrared wavelengths of 9.36 µm, which is a biomolecular kinetic energy.

The far-infrared wavelength of the 8 ~ 12㎛ band has been verified in various clinical trials in Korea to strengthen the immune function by increasing the capillary expansion and blood circulation promoting effect by activating living cells through the 40mm depth in the skin cells.

In the present invention, the far-infrared wavelengths as described above are mixed so as to be radiated. At this time, the ore uses the ore of Korea Ore Mining Co., Ltd., Yeongwol, Gangwon-do.

Such, ore is used 150 to 500 mesh, more preferably 325 mesh.

When using the ore below the threshold of the mesh described above, the density of the tissue is reduced, the surface is partially agglomerated, and a smooth surface is not obtained. When the threshold is exceeded, the overall viscosity is increased by the granulated bioore. Workability is not easy.

In addition, in the present invention, the raw ore is used by mixing 10 to 15% by weight relative to the total weight, if the mixing is less than the threshold value can not be expected to effect due to far-infrared wavelength radiation, if it exceeds the threshold viscosity The problem is that it becomes difficult to secure proper workability due to the increase.
