  In such a conventional humidifier, generally supplied water is tap water, and water contains trace amounts of elements such as silicon, calcium, and magnesium, so the vaporization filter that supplies the water dries. In the process, it is deposited as a scale on the surface of the filter. When the water supply to the vaporization filter is due to natural suction, the water suction effect is significantly reduced along with this scale precipitation. Therefore, it is necessary to periodically remove the deposit on the vaporization filter to maintain the humidification capacity. In addition, the vaporization filter has been required to have a long life and durability to withstand cleaning.

  In addition, in the method in which dry air is passed through a vaporization filter that has sucked up water, trace amounts of compounds containing elements such as silicon, calcium, and magnesium contained in the supplied water, bacteria, and mold also enter the vaporization filter. Therefore, there is a problem that even after washing, the dirt is not easily removed and cannot be kept clean.

  The present invention solves such a problem, and provides a humidifying device that can maintain a humidifying ability even if a scale is deposited on a vaporizing filter and has a long life that can exhibit a high humidifying ability over a long period of time. The purpose is that.

  Moreover, the thickness produced by the surface of the opening of a vaporization filter and the back surface with an opening is characterized by being 5 mm or more.

  In addition, the vaporization filter has a cylindrical shape.

  Moreover, the air heated by the air heating means is sent to the vaporization filter.

According to the present invention, it is possible to provide a long-life humidifying device that exhibits a high humidifying ability over a long period of time and can maintain the humidifying ability without being easily deteriorated in air permeability even when scale is deposited on the vaporization filter. Water does not enter the interior of the substrate, and therefore the surface of the substrate is soiled, but the interior of the substrate is not soiled or bacteria are propagated, so it can be easily washed and kept clean, and The present invention provides a humidifier equipped with a vaporizing filter that can withstand washing.

The invention according to claim 1 of the present invention includes a vaporization filter, a water tank, and an air blowing means, and the vaporization filter rotates while immersing a part of the lower part of the vaporization filter in the water tank to supply water to the vaporization filter. In the humidifying device for sending humidified air by sending air to the vaporizing filter wetted by the blowing means, the vaporizing filter is a hollow cylinder, and the hollow cylinder is provided with a back surface having an opening on the inner cylinder side. opening with a surface having an opening in the outer tube side, the vaporizing filter is composed of an inorganic material, and a back surface that is a surface with the opening of said aperture are connected by fibers, the opening and the back surface of said surface three-dimensional structure der comprising communicates is, air sent into the vaporizing filter by the blowing means, the opening of the rear surface of the inner tube side of the hollow cylinder from the opening of the outer cylinder side surface of the hollow cylinder And then the previous Through the hollow of the hollow cylinder, which is then humidified and wherein the passing Rukoto the opening surface of the outer tube side of the hollow tube from the inner tube side of the back surface of the opening of the hollow cylinder. Since inorganic materials are excellent in heat resistance and moisture resistance, there is little deterioration of the inorganic material itself in an atmosphere of repeated wetting and drying, so that it has the effect of imparting durability to the vaporization filter and is stable over a long period of time. Humidification performance can be demonstrated. Further, since air passages are secured by the openings on the front surface and the back surface, even if scale is deposited on the vaporization filter, the air permeability is unlikely to decrease, and the humidification ability can be maintained.

  In addition, the amount of water present on the vaporization filter can be kept optimal by controlling the amount of water supply and changing the surface properties and the number of fibers of the three-dimensional structure of the vaporization filter. It is possible to design a vaporization filter having the humidification performance required for the above. In addition, if a metal is used as the inorganic material, water does not enter the inside of the base material constituted by the fibers of the vaporization filter, and the base material surface is soiled, but the base material interior is not soiled and can be easily cleaned. Moreover, since the antibacterial property of the metal can prevent the bacteria from growing on the vaporizing filter, the vaporizing filter can be kept clean.

  In addition, the vaporization filter includes metal fibers. Since the metal is excellent in durability, the lifetime of the vaporization filter can be extended. In addition, since the inorganic material contains a metal, in a humidifying device having a heating means, heat generated from the heating means can be efficiently taken in and transferred to water, and water is easily vaporized, so that the humidification efficiency is increased. it can.

  The vaporization filter contains an antibacterial metal. If the antibacterial metal such as copper, silver, or zinc is included, it can prevent the bacteria and mold from growing on the vaporization filter. Can be kept clean.

  Further, the vaporization filter is characterized by containing glass fiber. If glass fiber is chemically stable, corrosion due to oxidation does not occur and the durability is excellent, so that the lifetime of the vaporization filter can be extended. . In addition, since it is transparent and does not deteriorate with light, it can maintain a stable humidifying performance for a long period of time even in an environment where it is exposed to light.

  In addition, the vaporization filter is characterized by comprising two or more kinds of inorganic materials. If two or more kinds of inorganic materials are used, in addition to the properties such as the durability of the inorganic materials, the characteristics of each inorganic material Can be added to the vaporization filter. For example, by selecting an antibacterial metal for the front and back surfaces and a metal such as a highly rigid wire for the connecting fiber, a vaporization filter with antibacterial properties and shape stability can be obtained. The filter can be designed freely.

  Further, the vaporization filter is provided with fine irregularities, the surface area of the vaporization filter can be increased, and the contact area between water and air is increased, so that the humidification efficiency can be increased. The fine irregularities may be any irregularities as long as the contact area between water and air is increased. For example, the irregularities are approximately 0.1 μm to 100 μm.

  In addition, the photocatalyst is supported on the vaporization filter, and because the photocatalyst becomes strongly hydrophilic by light irradiation, water spreads thinly on the vaporization filter surface, improving the contact efficiency between the passing air and water, High humidification performance can be obtained even with a compact size. Moreover, since the photocatalyst can decompose organic substances by light irradiation, the vaporization filter can be kept clean. At this time, if the three-dimensional structure is a glass fiber, the glass fiber is transparent and allows light to efficiently shine on the photocatalyst. Further, since the glass fiber is not easily photodegraded, the lifetime of the vaporization filter can be extended.

  In addition, the vaporization filter is characterized by not having water absorption, and water is not absorbed inside the fibers of the vaporization filter, so that the inside of the substrate composed of fibers is not contaminated and can be easily washed. The vaporization filter can be kept clean. Here, having no water absorption means that water does not permeate to the central part of the base material constituted by the fibers of the vaporization filter.

  Further, there are 18 or more fibers connecting the front surface and the back surface of the vaporization filter having openings, and the fibers can maintain a sufficient amount of water. Moreover, the contact area with air can be enlarged and high humidification performance can be obtained.

  Also, the diameter of the fiber connecting the front and back surfaces of the vaporization filter with the opening is 1 mm or less, and the air passage is secured by reducing the volume of the fiber relative to the air passage. It is possible to suppress the increase in pressure loss during water supply, and energy saving and silent effect can be obtained during humidification operation.

  Further, the diameter or the longest diagonal of the vaporization filter has a diameter of 2 mm or more, and water does not form a film to block the opening, thereby suppressing an increase in pressure loss during water supply. Energy saving and noise reduction effect can be obtained during humidification operation.

  In addition, the shape of the opening of the vaporization filter is substantially circular or regular polygonal, and water does not form a film to block the opening, so that the pressure loss during water supply increases. Since it can be suppressed, energy saving and silent effect can be obtained during humidification operation.

  In addition, the thickness created by the front and back surfaces of the opening of the three-dimensional structure is 5 mm or more, and the thickness, that is, the amount of water retained by the fibers connecting the front and back surfaces is sufficient. At the same time, sufficient time for the air passing through the vaporizing filter to come into contact with water is obtained, so that high humidification performance can be obtained.

  In addition, since the vaporization filter has a cylindrical shape and water can be uniformly supplied to the entire vaporization filter by rotating the cylindrical vaporization filter, humidification can be stably performed for a long time. Further, if a part of the lower part of the vaporization filter is rotated while being immersed in the water tank, it is not necessary to provide a nozzle or a pump as water supply means, and water can be supplied with the water tank. Moreover, when rotating a cylindrical vaporization filter, the quantity of the water hold | maintained on a vaporization filter can also be controlled by changing a rotational speed.

  The humidifier according to any one of claims 1 to 14, wherein the air heated by the air heating means is sent to the vaporization filter. The saturated water vapor amount of the air passing through the filter is increased, and a higher humidification capacity can be obtained. Moreover, a halogen lamp, a nichrome wire, etc. are mentioned as an air heating means. If a photocatalyst is used for the vaporization filter if a material that emits ultraviolet light and heat such as black light is used, the photocatalyst becomes strongly hydrophilic due to light irradiation, so water spreads thinly and widely on the vaporization filter surface, and the passing air and The contact efficiency with water is improved, and high humidification performance can be obtained even with a compact size. Moreover, since an organic substance can be decomposed | disassembled by light irradiation, a vaporization filter can be kept clean.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, a hollow cylindrical vaporization filter 16 made of a three-dimensional structure in which a surface 12 having an opening 11 made of an inorganic material and a back surface 14 having an opening 13 are connected by fibers 15 made of an inorganic material, In the humidifier provided with the water tank 17 as the water supply means and the fan 18 as the air blowing means, the vaporization filter 16 rotates while immersing a part of the lower part in the water tank 17, and holds the water pumped up on the vaporization filter 16. . This is a mechanism in which air is passed through the vaporization filter 16 holding water by a fan 18 and humidified air is sent indoors. At this time, by disposing the heater 19 as an air heating means in front of the vaporization filter, the temperature of the inflowing air can be raised and the saturated vapor pressure can be raised, so that more humidification can be performed.

  In a humidifier that supplies water to a vaporization filter formed by connecting a front surface with an opening and a back surface with an opening with a fiber, an air passage is secured by the opening on the front surface and the opening on the back surface. Even if it precipitates, the air permeability is hardly lowered and the humidifying ability can be maintained. In addition, the amount of water retained on the vaporization filter can be controlled by changing the type, number, and shape of the front and back surfaces of the three-dimensional structure and the fibers connecting them, and excessive amounts on the vaporization filter can be controlled. Water causes pressure loss, but pressure loss can be reduced because excessive water is not present on the vaporization filter. Also, by changing the type, number, and shape of the fibers, the surface area of the vaporization filter can be increased, and the contact efficiency between the air passing through and the water present on the vaporization filter can be increased. High humidification performance can be obtained.

In addition, in the case of a three-dimensional structure in which the front surface with the opening and the back surface with the opening are connected by fibers, the advantage is that the surface area is large compared to the honeycomb structure formed by corrugating the sheet. There is. For example, when compared with a regular hexagonal opening with a side of 2 mm and a vaporization filter with a thickness of 10 mm, the surface area of one side is 20 mm ² in the sheet form, but when one side is connected by 20 fibers having a diameter of 100 μm, it is about The surface area is about 3 times as large as 63 mm ² .

  The shape of the vaporization filter is not particularly specified, but if the vaporization filter is cylindrical, it can be uniformly supplied to the entire vaporization filter by rotating it. It can be performed. In addition, if a part of the lower part of the vaporization filter is rotated while immersed in the water tank, there is no need to provide a nozzle or pump as water supply means, water can be supplied with the water tank, and the humidifier is made compact. be able to. Moreover, when rotating a cylindrical vaporization filter, the quantity of the water hold | maintained on a vaporization filter can also be controlled by changing a rotational speed. Although the optimum rotation speed varies depending on the water retention and size of the vaporization filter, for example, in the case of a vaporization filter having a hydrophilic diameter of 100 mm as a whole, it may be rotated at about 2 rpm. The cylindrical vaporization filter may not be hollow. In addition, although the cylindrical shape was mentioned as an example, if it is a cylinder, other shapes may be sufficient.

  Further, the type of heater is not particularly defined, and examples of the heater include a halogen lamp and a nichrome wire. If a photocatalyst is used for the vaporization filter if a material that emits ultraviolet light and heat such as black light is used, the photocatalyst becomes strongly hydrophilic due to light irradiation, so water spreads thinly and widely on the vaporization filter surface, and the passing air and The contact efficiency with water is improved, and high humidification performance can be obtained even with a compact size. Moreover, since the photocatalyst can decompose organic substances by light irradiation, the vaporization filter can be kept clean. Examples of the photocatalyst include titanium dioxide.

(Embodiment 2)
As shown in an example of the cross section of the vaporization filter in FIG. 2, the vaporization filter 21 connects a front surface 23 made of an inorganic material having an opening 22 and a back surface 24 made of an inorganic material having an opening 22 with a metal fiber 25. A three-dimensional structure 26 is formed.

  In the above configuration, if the inorganic material constituting the three-dimensional structure is a metal, the lifetime of the vaporization filter can be extended because of excellent durability. In addition, when the inorganic material contains a metal, for example, in a humidifying device having a heating means, heat generated from the heating means can be efficiently taken in and transferred to water, and the water is easily vaporized to increase the humidification efficiency. be able to.

  In addition, if the three-dimensional structure is an antibacterial metal, such as copper, silver, zinc, etc., it is possible to prevent the growth of bacteria and mold on the water and the vaporization filter and keep the vaporization filter clean. .

  In addition, since the metal does not absorb water, it does not absorb water inside the base material composed of the fibers of the vaporization filter, so the inside of the base material is not contaminated, and it is only necessary to clean the surface and can be easily cleaned. Therefore, the vaporization filter can be kept clean.

(Embodiment 3)
As shown in FIG. 3, a three-dimensional structure 35 formed by connecting a surface 32 having an opening 31 as a base material for a vaporization filter and a back surface 33 having an opening 31 with fibers 34 of an inorganic material is used. And the longest diagonal line A of the opening of the back surface 33 is 2 mm, the thickness B is 5 mm, the diameter of the fiber 34 connecting the front surface 32 and the back surface 33 is 1 mm, and the fiber 34 connecting the front surface 32 and the back surface 33 is one opening. There are 18 of them.

  When the longest diagonal line A of the opening is smaller than 2 mm, the water supplied by the water supply means may form a film on the opening of the vaporization filter to block the opening, and to suppress an increase in pressure loss during water supply The longest diagonal line A may be 2 mm or more. Specific shapes of openings include circles and polygons, but in the case of polygons, if the regular polygons have the same length for all sides, the water forms a film compared to the other shapes and the openings It is easy to suppress blocking. The shapes of the openings need not be the same, and can be formed by combining hexagons and triangles, for example. Similarly, the size of each opening need not necessarily be uniform, and a combination of sizes according to need may be selected.

  Further, if the thickness B formed by the front surface with the opening and the back surface with the opening is 5 mm or more, the thickness, that is, the amount of water held by the fiber connecting the front surface and the back surface is the amount necessary for humidification. Since it is obtained more than equivalent, the contact efficiency between the passing air and water can be increased. When the thickness B is less than 5 mm, sufficient water does not exist on the vaporization filter, and sufficient time for the passing air to contact the water is short, so that sufficient humidification performance cannot be obtained.

  Moreover, if the diameter of the fiber connecting the front surface with the opening and the back surface with the opening is 1 mm or less, the air passage can be secured by reducing the volume occupied by the fiber with respect to the air passage. Moreover, since the surface area which hold | maintains water can be increased when the volume which a fiber occupies is the same compared with when using a fiber thicker than 1 mm, the contact efficiency of air and water can be improved. For example, when the diameter of the connecting fiber is 1 mm and when it is 3 mm, the use of 20 1 mm diameters and the use of 2 3 mm diameters are almost the same as the volume occupied by the fibers in the air passage. At this time, as the surface area for holding water, the area of the connecting fiber having a diameter of 1 mm can obtain an area approximately three times as large as the case of using the diameter of 3 mm.

  Further, if there are 18 or more fibers for connecting the front surface with the opening and the back surface with the opening to one opening, the fiber can hold more water, and the contact efficiency between the passing air and water can be improved. And high humidification performance can be obtained. As for the connecting fibers, 18 or more fibers having the same diameter may be used, or fibers having different diameters may be mixed and used. For example, if 5 thick fibers with a diameter of 1 mm and 100 thin fibers with a diameter of 0.05 mm are used in combination, the surface of the vaporization filter is increased by the thin fibers while the vaporization filter is maintained with the thick fibers, and humidification is performed. Efficiency can also be improved.

(Embodiment 4)
As shown in an example of a cross section of the vaporization filter in FIG. 4, the vaporization filter 41 has a photocatalyst formed on a three-dimensional structure 46 formed by connecting a front surface 43 and a rear surface 44 made of a metal having an opening 42 with glass fibers 45. The titanium dioxide 47 is supported as fine particles and is provided with fine irregularities.

  In the above configuration, the method for providing fine irregularities on the vaporization filter surface is not particularly limited to the method for applying photocatalyst particles, and other methods such as imparting irregularities to the fiber itself, or supporting fine particles such as a photocatalyst, etc. Is mentioned. At this time, if a binder is used to carry the fine particles, the fine particles can be prevented from falling off. By providing fine irregularities on the surface of the vaporization filter, water droplets can be held on the fine irregularities on the fiber surface, and the connected fibers can hold more water. Contact efficiency can be increased. The fine irregularities may be any irregularities as long as the contact area between water and air is increased. For example, the irregularities are approximately 0.1 μm to 100 μm.

  Moreover, although titanium dioxide was mentioned as an example as a photocatalyst, it is not specifically limited to this.

  In addition, when the three-dimensional structure is composed of two or more different types of fibers as in the above configuration, by selecting the type of the fibers, necessary functions such as shape retention and light transmission are required. Can be given. For example, if the front and back surfaces are hard fibers, and metal fibers such as wires are used, it is easy to maintain the opening shape, and if the fibers connecting the front and back surfaces are made of glass fibers, The photocatalytic activity can be enhanced when the photocatalyst is supported because of its excellent light transmittance. Moreover, since glass fiber is excellent in light resistance, the effect of extending the lifetime of a vaporization filter is acquired. At this time, the effect of the photocatalyst is due to decomposition of organic substances and odor-causing substances, antibacterial properties, and strong hydrophilicity when exposed to light, and the supplied water spreads thinly on the vaporization filter. The contact efficiency is improved, and an effect that high humidification performance can be obtained even when compact is obtained.

Example 1
By using a wire having a diameter of 0.69 mm, a square having an arbitrarily selected diagonal length was created, which was used as an index of the opening size of the three-dimensional structure. At the same time, the same square was created with a wire having the same diameter processed to be hydrophilic by applying hydrophilic silicon and a wire having the same diameter processed to be water-repellent by applying a fluororesin. Whether or not a water film was formed when these squares were immersed in water, and if a water film was formed, the fragility of the water film was evaluated as the water film strength.

  An example of the result is shown in FIG. In the graph shown in FIG. 5, the vertical axis represents the water film strength. At this time, the water film strength indicates 0: water film cannot be formed, 1: disappears immediately, 2: disappears if wind is applied, 3: water film does not disappear unless strong wind is applied. With the untreated wire, when the diagonal length was 11 mm or less, a water film that would not disappear unless a strong wind with a water film strength of 3 was given. On the other hand, with a wire subjected to hydrophilicity or water repellency treatment, a water film is less likely to be formed than in the case of no treatment, and both have a water film strength of 2 or less when the diagonal length is 2 mm or more. Similarly, even when a wire having a diameter of 0.49 mm was used, the water film strength was 2 or less when the diagonal length was 2 mm or more, if hydrophilic or water-repellent treatment was performed. Therefore, if the diagonal line of the three-dimensional structure constituting the vaporization filter is 2 mm or more, water will not form a film and block the opening. It can be said that it can be suppressed.

(Example 2)
Using a wire having a diameter of 0.43 mm, two types of quadrangles having the same opening area of 4 mm × 4 mm and 2 mm × 8 mm were prepared. When these squares were immersed in water, whether or not a water film was formed, and if a water film was formed, the fragility of the water film was evaluated as water film strength.

  The result is shown in FIG. In the graph shown in FIG. 6, the vertical axis represents the water film strength. The water film strength was 1 when the length of one side of the square was 4 mm × 4 mm, whereas the water film strength was 3 when the square was 2 mm × 8 mm. At this time, the water film strength indicates 0: water film cannot be formed, 1: disappears immediately, 2: disappears if wind is applied, 3: water film does not disappear unless strong wind is applied. The same experiment was performed with different wire diameters and different opening areas, and similar results were obtained. Therefore, in the same opening area, if the shape of the opening is a regular polygon or a circle, water does not form a film and block the opening, so that an increase in pressure loss during water supply is suppressed. Can be said.

  It is possible to provide a vaporizing filter capable of exhibiting a high humidifying capacity over a long period of time and maintaining the humidifying ability even if scale is deposited on the vaporizing filter, and a humidifying device using the vaporizing filter of the present invention. It can also be applied to humidifiers and air conditioners.
