Smart antibacterial dryer{SMART ANTIBACTERIAL DRYING MACHINE}

The present invention relates to a smart antibacterial dryer. More specifically, it relates to a smart antibacterial dryer that can simultaneously exhibit not only a drying effect but also an excellent antibacterial effect against harmful bacteria by using the photodecomposition activity of a filter coated with a photocatalyst.

In modern society, the number of single-person households is rapidly increasing due to changes in family structure, and research on various types of home appliances to meet the needs of single-person households is also actively underway.

Specifically, the need for small home appliances is increasing due to the increase in single-person households, and home appliances such as small refrigerators and wine cellars are attracting attention. In fact, small home appliances are showing gradual development and are becoming more advanced. There is a need for research on various types of small home appliances with different functions.

Accordingly, the present applicant has been conducting research to miniaturize dryers so that various types of objects, such as shoes and clothing, can be easily dried in each home as a home appliance to meet the demands of single-person households.

Specifically, looking at the prior technologies (Korean Patent Registration No. 10-256101) that disclose technology for dryers, they have structural features including a heater, an ozone gas generator, and an air blower, and use heated air through them. The technical feature is that it evaporates the moisture of the object inside and dries it, while additionally utilizing the sterilizing effect of ozone.

However, since the dryers of the prior art are large in size and require a separate installation space, there is a problem of space limitations for home use.

In addition, there was also the problem that ozone used to demonstrate the sterilization effect could act as a harmful substance to some extent and that the sterilization effect through the application of ozone was minimal.

Meanwhile, in the process of modernization in our society, the earth's resources are limited, but the problem of gradual depletion of the earth's resources due to indiscriminate use of various resources has been continuously raised, and environmental problems caused by fossil fuels used in the modernization process are increasing. It is emerging as an opposite effect of modernization.

In order to solve the above problems, interest in removing contaminants such as harmful bacteria using photocatalysts, which is one of the advanced oxidation technologies, is increasing.

Photocatalysts are substances that do not change before or after a reaction but are defined as those that promote a reaction by absorbing light. The photocatalytic effect was developed by Fugishima and Honda in Japan in the early 1970s. When light was irradiated using platinum as the cathode and titanium dioxide as the anode, water was separated into oxygen and hydrogen through photooxidation and photoreduction reactions. After discovery, follow-up research was conducted.

Specifically, the photocatalyst is a material that has the advantage of being able to safely and easily decompose various chemical substances just by using light energy and has properties such as antibacterial, sterilizing, and superhydrophilic properties, and is receiving great attention as a promising technology field in the 21st century.

Accordingly, the present applicant conducted research to miniaturize existing dryers and achieve antibacterial effects through additional eco-friendly methods.

Specifically, we have developed a smart antibacterial dryer that can exhibit an antibacterial effect by decomposing harmful substances using natural substances that exhibit photodecomposition activity and antibacterial properties through UV irradiation of the photocatalyst.

The main body 100 forms the external framework of the smart antibacterial dryer of the present invention, and its size and material are not limited, and are defined to include sizes and materials that can be applied by those skilled in the art.

Meanwhile, the main body 100 includes a cover 200, and the cover 200 is formed to enable opening and closing of the main body 100, and the main body 100 can be opened and closed through the cover 200. Part of (100) can be opened and closed.

The rotating plate 300 is provided on the inner lower surface of the main body 100 and can be rotated 360°. In other words, by rotating the drying and antibacterial object located on the rotary plate 300 by 360°, it has the advantage of being able to receive the action of the hot air blower 500 evenly and ultimately improving the drying and antibacterial efficiency.

Meanwhile, light emitted from the lamp unit 400 may act on the photocatalyst filter unit to induce a photocatalytic reaction.

In other words, the light emitted from the lamp unit 400 can act on the metal oxide adsorbed on the photocatalyst filter unit to cause photocatalytic activity, thereby exhibiting an antibacterial effect against contaminants such as harmful bacteria, which is the object of the present invention. You can.

Specifically, when the light emitted from the lamp unit 400 acts on the photocatalyst filter unit, the photocatalytic activity of the metal oxide adsorbed on the filter unit can be induced, and the light provided inside the main body unit 100 Due to the action of hot air generated from the hot air blower 500, the photocatalytic activity is transmitted to the object through the air, thereby exhibiting antibacterial and drying effects.

The lamp unit 400 is preferably a UV lamp unit 400, but is not limited thereto as long as it can emit light of a wavelength capable of exhibiting the photocatalytic activity.

Examples of data processing devices built into hardware include microprocessors, central processing units (CPUs), processor cores, multiprocessors, and application specific integrated circuits (ASICs). ), and processing devices such as FPGA (field programmable gate array), but the scope of the present invention is not limited thereto.

Preferably, the main body 100 may further include a display unit 800. Through the display unit 800, the user can visually check the status of the dried and antibacterial object present inside the main body 100 from the outside.

The photocatalyst filter unit has titanium dioxide (TiO ₂ ) particles coated on the filter surface.

The photocatalytic filter unit means that titanium dioxide (TiO ₂ ) particles are coated on the surface of a filter in the form of a mesh made of a metal material selected from the group consisting of Ag, Cu, and Zn.

The titanium dioxide (TiO ₂ ) is known to have high oxidation-reduction power and excellent photocatalytic ability, is inexpensive, is very stable physicochemically, and is harmless to the human body.

The titanium dioxide (TiO ₂ ) may exist in crystalline forms such as anatase, rutile, and brookite. In the present invention, anatase and rutile phases with particularly high photocatalytic activity are used. ₂ ) can be used. Anatase and rutile phase TiO ₂ have bandgap energies of 3.2 eV and 3.0 eV, respectively, and their photocatalytic activity appears in the ultraviolet (UV) region with a wavelength of 400 nm or less.

Meanwhile, when light energy exceeding the bandgap energy is irradiated to the surface of titanium dioxide (TiO ₂ ), electrons in the valence band transition to the conduction band, creating electron (e-) and hole (h+) pairs. Holes generated in the valence band contribute to the oxidation reaction and react with water molecules adsorbed on the surface to generate hydroxyl radicals (OH) or oxidize organic substances through a direct reaction. The electrons generated in the conduction band cause a reduction reaction of oxygen molecules to form superoxide ions (O ^2- ), which then generate hydroxyl radicals through several stages of reaction. Organic matter can be decomposed into carbon dioxide and water by hydoxyl radicals generated by holes and electrons, and it can also have a sterilizing effect on harmful bacteria, which are pollutants.

In other words, ultraviolet rays emitted from the UV lamp unit 400 can act on titanium dioxide (TiO2) adsorbed on the photocatalyst filter unit to cause photocatalytic activity, thereby preventing contaminants such as harmful bacteria, which is the object of the present invention. It may have an antibacterial effect.

Specifically, when the light emitted from the lamp unit 400 is ultraviolet light, the ultraviolet rays act on the photocatalyst filter unit to induce photocatalytic activity of titanium dioxide (TiO2) adsorbed on the filter unit, and the main body. Due to the action of hot air generated from the hot air blower 500 provided inside the unit 100, the photocatalytic activity is transmitted to the object through the air, thereby exhibiting antibacterial and drying effects.

The thickness of the photocatalyst filter part is 1.5 to 2.5 mm.

However, the thickness of the photocatalyst filter part is a range that can exhibit optimal photocatalytic activity through the action of the lamp part 400 and the heater 500, and is not limited thereto as long as it is within a thickness range that can be applied by a person skilled in the art. .

Meanwhile, the photocatalytic filter unit may be provided to be detachable and attachable to the inside of the main body 100, which facilitates replacement of only the filter unit, so that the filter unit can be easily replaced unless a mechanical defect occurs in the antibacterial dryer itself. It has the advantage of being able to be used for a long time by replacing only the parts.

The inner surface of the main body 100 may include a deodorizing coating layer.

Specifically, the objects subject to drying and antibacterialization using the smart antibacterial dryer of the present invention not only contain contaminants such as harmful bacteria, but also often contain a large amount of moisture, so the antibacterial dryer is repeatedly used for a long period of time. There is a problem that odors, etc. may remain in the internal space of the antibacterial dryer main body 100 due to use. In addition, bad odors may seep into the inner surface of the main body 100, causing long-term maintenance problems, and ultimately reduce antibacterial and drying efficiency.

Accordingly, the present invention has the advantage of effectively eliminating the problem of internal odor that may occur when using the smart antibacterial dryer for a long period of time by forming a deodorizing coating layer on the inner surface of the powder unit.

The deodorizing coating layer includes a deodorizing coating composition, and the deodorizing coating composition includes fine powder shungite, fine powder illite, fine powder zeolite, fine powder elvanite, fine powder bentonite, fine diatomaceous earth, fine powder germanium, and fine powder. It may include an inorganic powder selected from the group consisting of red clay, fine alumite, fine powder jade, and mixtures thereof.

The fine powder referred to in the present invention refers to a product manufactured to have the properties of a fine powder by crushing it with a ball mill, jet mill, or other grinding device, or during a synthesis process, and the fine powder is defined as having an average particle diameter of 100 μm or less.

The gaite referred to in the present invention is formed as a layer (up to 2 m thick) or lenticular body in a shale of low metamorphism rich in small graphite microcrystals of the Jatulian period of the Proterozoic Era in Shunga near the northern part of Lake Ladoga, Karelia, Russia. .

Illite as used in the present invention has a chemical composition of (K,H ₃ O)Al ₂ (Si,Al) ₄ O ₁₀ (H ₂ O,OH) ₂ . In terms of chemical composition, there are some that are close to muscovite, but they contain relatively more SiO ₂ , MgO, and H ₂ O and less K ₂ O. It is a mineral of the same series as white mica. Hardness is 1 to 2, specific gravity is 2.6 to 2.9. The cleavage is complete, the streak color is white, and there is an earthy sheen. Judging from its chemical composition and crystal structure, there is a view that it is not an independent mineral, but a mixed mineral containing other components. It is produced in aluminum-rich heterogeneous or tuffaceous sedimentary rocks, and as an altered mineral in hydrothermal ore-like host rocks.

The zeolite referred to in the present invention is also called zeolite. There are many types, but they have commonalities such as high water content, crystal properties, and acid phase. The hardness does not exceed 6, and the specific gravity is about 2.2. It is generally colorless and transparent or white and translucent. It got this name because it boils and expands when heated with a blowpipe. Most types dissolve in hydrochloric acid, often forming a glue-like shape, but a few types do not dissolve in hydrochloric acid. The main types include argillite, fisheye, chabazite, soda zestite, hylandite, stilbite, lomontite, and inesite. It is produced in cavities or rifts of basic igneous rocks such as basalt and pyroxene tuff, and sometimes exists as a secondary mineral in granite and gneiss. In addition, there are cases where it is produced in gold veins and other mineral veins. In terms of the crystal structure, the bonds between each atom are loose, so even if the moisture filling the space is released at high heat, the skeleton remains intact, allowing it to adsorb other fine particles. This property is used as an adsorbent and as a molecular sieve to separate fine particles of different sizes.

The elvan stone referred to in the present invention is known as a term used in Chinese oriental medicine, and geologically classified, it belongs to the granite class. It is similar to quartz porphyry, feldspathic porphyry, and granite porphyry, and its rock name is identical to quartz-monzonite. Quartz and feldspar are closely mixed. The yellowish white, light yellowish brown, light gray, dark green or light green rocks with red or white dots evenly mixed together resemble rice balls made from barley, hence the name Elbanseok. The main ingredients are silicic anhydride and aluminum oxide, and a small amount of iron oxide is contained. Known as a medicinal stone, it is a yellowish-white elvan stone that was used in the past as a filter for refining pills and as an anti-inflammatory agent to treat skin diseases such as scabs or boils on the back. According to Donguibogam, its properties are sweet, warm, and non-poisonous. It has 30,000 to 150,000 pores per ^1cm3 , so it has strong adsorption properties and contains about 25,000 types of inorganic salts. Because it acts to exchange heavy metals and ions, it is also used as a harmful metal remover, and it is known to emit far-infrared rays when heat is applied to this rock. Because of these characteristics, it is used in various industries such as saunas, tableware, and medical equipment.

The bentonite referred to in the present invention often contains quartz, feldspar, zeolite, etc. Colors include white, gray, light brown, and light green. It is produced as a dense mass with a pearly luster and waxy luster and a fatty feel, and has similar properties to montmorillonite, including swelling by adsorbing water and clear cation exchange properties. Tuff and glassy rhyolite are altered. Its uses are very wide, and it is used as the main ingredient of mud for oil drilling, a binder for castings, an mixing agent for ceramic raw materials, and a base for ointments. The name comes from the strata of Wyoming, USA, where it was discovered.

The diatomaceous earth referred to in the present invention is mainly made of silicic acid (SiO ₂ ) and is white or off-white in color. It is light and soft enough to feel powdery when touched with a finger. Because it is finely porous, it has strong absorption properties and is a poor conductor of heat. In our country, diatomaceous earth is produced as soil within the Tertiary or Quaternary strata. During the Paleogene III period in Korea, fault movement in the northeast or north-northeast direction occurred, forming rift valley sedimentary basins in several places. The Yeongil Basin, the rift zone between Gilju and Myeongcheon, the rift zone between Seoul and Wonsan, and the Duman River Basin were formed, and the Tertiary layer was deposited here. When sedimentary layers were formed, diatoms were deposited here and there in small, shallow lakes or freshwater basins, forming mineral deposits. Among these sedimentary basins, the diatomaceous earth in Yeongil Bay is the largest diatomaceous earth deposit and is found concentrated in Wolseong and Yeongil, Gyeongsangbuk-do. In addition, in North Korea, Haenghyeon-ri, Munsan-myeon, Anbyeon-gun, South Hamgyong Province, Namsan-ri, Anbyeon-myeon, Anbyeon-gun, Bupyeong-dong, Junam-myeon, Gyeongseong-gun, North Hamgyong Province, Hoemun Mine, Jubuk-myeon, Gyeongseong-gun, Sanbon Mine, Ungpyeong-myeon, Gilju-gun, Myeongcheon Mine, Myeongcheon-gun, Seomyeon Baekrok Mine, Myeongcheon-gun, Gangwon-do Production areas such as Sephori, Gosap-myeon, Pyeonggang-gun, etc. are known. The development of diatomaceous earth as a mineral deposit in our country began in 1941 when it was incorporated as a designated statutory mineral under the Joseon Mining Ordinance. Afterwards, diatomaceous earth deposits were discovered in various places in the country, and in particular, diatomaceous earth produced in Iil-ri, Yangbuk-myeon, Wolseong-gun, Gyeongsangbuk-do was said to have been used as a raw material for the manufacture of Japan's Asahi stove in Nodong-ri, Gyeongju-si. In recent years, it is used as a fireproof material, and because of its strong absorbency, it is mostly used as a filter medium for purifying industrial water, tap water, medicine, food, etc. In addition, it is used as a filler for plastics and paper, an adsorbent for dynamite, a hemostatic agent, and a mixture of cement.

Germanium as used in the present invention has the element symbol Ge, atomic number 32, and atomic weight 72.59±3. Its existence was predicted by D. I. Mendeleev in 1871 and it was called ekasilicon, but in 1886, it was discovered in silver germanium stone (Ag GeS) by German chemist C. A. Winkler and was named after the Latin name for Germany, “Germania.” Because it is similar to silicon, it exists widely in the earth's crust in place of silicon in silicates. It is also contained in sulfide minerals and coal containing copper and zinc, but there are very few minerals that mainly contain germanium.

The alum stone referred to in the present invention is also called alum stone. The chemical composition is KAl ₃ (SO ₄ ) ₂ (OH) ₆ . It appears as hexagonal plate-shaped or granular crystals, and is usually lumpy or granular. The hardness is 3.5 to 4 and the specific gravity is 2.6 to 2.9. The crystal type has complete cleavage on the bottom, and the cleavage surface has a pearly luster. The odd ones lack luster. It is white, gray, and sometimes red, yellow, or reddish brown. The streak color is white. It is insoluble in hydrochloric acid, but soluble in potassium hydroxide or hot sulfuric acid. It is produced in volcanic rock areas that have undergone hydrothermal alteration.

Jade as used in the present invention refers to something that is dense, hard, transparent, shines beautifully, and is polished to shine. Mineralogically, nephrite is a type of amphibole, and jadeite is a type of alkali pyroxene. Nephrite is often milky white, but also has green, yellow, and red colors, while jadeite is green and white. There are various names depending on the color, but white jade and jade are representative ones. It has been prized in the East since ancient times, and has been crafted and used as decorative stone and jade tools. Nephrite occurs as veins in crystalline schist or gneiss in places such as Turkey, and in the contact zone of granite in northeastern China. Jadeite is produced in veins among serpentinites in Myanmar, and is also produced in Yunnan, China and the Tibetan Plateau. Although jade in a narrow sense refers to jade, the present invention is not limited thereto, and jade as used in the present invention is defined to include all of the jade in the broad sense described above.

Preferably, the inorganic powder is heat treated by mixing with a solution containing any one selected from the group consisting of strontium ions (Sr ²⁺ ), calcium ions (Ca ²⁺ ), magnesium ions (Mg ²⁺ ), and mixtures thereof. It may be.

When the inorganic powder is mixed with a solution containing the ions and heat-treated, not only can the antibacterial power of the inorganic powder itself improve against bacteria (S. mutans, etc.), but also the deodorizing power against bad odors can be greatly increased. Preferably, It may be heat treated by mixing with a solution containing strontium ions (Sr ²⁺ ) and calcium ions (Ca ²⁺ ).

In the case within the above range, the interaction of the powders that make up the inorganic powder may result in an antibacterial and deodorizing effect beyond that of a simple combination.

The deodorizing coating composition may further include a first natural extract selected from the group consisting of Jeomnadonamul extract, P. ginseng extract, Hansokdan extract, and mixtures thereof.

The above-mentioned Cerastium holosteoides var. hallaisanense (Nakai) Mizushima) is a biennial plant of the dicotyledonous plant Centrophyllaceae and is grown on the edge of rural fields, ridges of rice fields, roadsides of farmland, and other areas from cold to warm temperate zones in all regions of Korea, China, Japan, and Taiwan. It grows wild on embankments, sandy gravel soil, and sunny areas. It is also called Ichae (耳菜), Gwoni (卷耳), Papa (婆婆), and Gwagitchae (指甲菜). Jeomnadonnamul is 15 to 25 cm tall and grows obliquely with branched branches. The leaves resemble the shape of a mouse's ears and are black-purple, and the edges of the leaves are smooth and have fine hairs. Flowers are white and grow on cyme inflorescences from April to June, and after the flowers fade, the ends of small flower stems bend downward. The fruit is light yellow-brown and about 9 mm long. Jeomnadonamul is a compound word of ‘jeom’, ‘nado’, and ‘namul’, ‘jeom’ meaning small like a dot, ‘nado’ meaning that although it is not original, it has a similar function or structure, and ‘namul’ means that it can be eaten, so it is very small and unattractive. Although it is a non-existent plant, it can be interpreted to mean that it can become an herb. In this respect, it is a weak weed, but it is a grass that continues its existence with persistent vitality. Jeomnadonnamul has the effect of reducing fever and swelling, so it is used for colds, mastitis, dermatitis, and boils. It tastes bitter and has a slightly cold nature, so it is better for people with a cold body or a weak pulse not to eat a lot.

The Siegesbeckia pubescens Makino is an annual herb of the Asteraceae family. It has a erect stem of about 50 to 100 cm in height and is purple in color, and the branches have dense gray-white long hairs. The leaves are ovate or ovate-triangular, face each other, have petioles, and are characterized by pointed tips and irregular sawtooth edges. Yellow flowers bloom at the ends of branches and main stems from August to September, and fruits appear from September to October. It is usually dried and used as an herbal medicine, and grows in abundance in the southern region of Korea and around the seaside.

Phytoncide refers to a natural antibacterial volatile substance emitted by trees to defend themselves from pests, microorganisms, and various bacteria. Phytoncide is mainly emitted from coniferous trees such as cypress trees, pine trees, pine trees, and fir trees. Phytoncide is a term created by combining the Greek words 'phyton' meaning 'of a plant' and 'cide' meaning 'kill'. Phytoncide is a natural healing ingredient emitted by plants and is a general term for bactericidal substances emitted by plants, and is highly volatile. Terpene oil is the main ingredient and consists of other phenolic compounds, alkaloids, and glycosides. The phytoncide reduces stress by reducing the body's hormone called cortisol, thereby increasing concentration and helping with a comfortable sleep. It also increases immunity against bacteria and allergies that cause atopy, and eradicates more than 98% of house dust mites, preventing atopy and allergies. It has a fundamental soothing effect on symptoms such as sexual rhinitis.
