[First embodiment]
A humidifying device 100 according to the first embodiment has a humidifying function. As shown in FIG. 1, the humidifying device 100 according to the first embodiment houses a blower unit 10 that blows air, a humidity control unit 20 that is provided in the blowing path of the blower unit 10, and the blower unit 10. and a body portion 30 . As shown in FIG. 2-5, the humidity control unit 20 is characterized by absorbing moisture in the air around the humidity control unit 20 and humidifying the air blown from the air blowing unit 10. .

Examples of the humidifying device 100 include a hair dryer, a hair care device, a scalp care device, a skin moisturizing device, and the like. Also, the air blower 10 may be any device as long as it can blow air, such as a fan.

As used herein, "humidity conditioning" refers to adjusting the amount of water vapor contained in the air. Humidity conditioning consists of "moisture absorption," which removes water vapor from the air to relatively reduce the amount of water vapor contained in the air, and "humidity absorption," which relatively reduces the amount of water vapor contained in the air by supplying water vapor to the air. Including both "humidification" which increases to

By using the humidity control material 21 as a means having a humidification function, the humidity control liquid 23 absorbs and releases moisture according to the relative humidity of the surrounding air, so that moisture is absorbed from the surroundings when not in use, and absorbed during use. Release moisture. This cycle uses ambient air moisture as a water source. The humidity control unit 20 humidifies the air blown by the air blowing unit 10, and humidification by the humidifying device 100 becomes possible.

Conventionally, devices such as hair care devices with a humidifying function have been disclosed. A water supply is required. In addition, the water source is water condensed by a Peltier, but the amount of water obtained from it is very small, and it is considered that a sufficient humidification function is not obtained.

Therefore, since the humidifying device 100 according to the present disclosure and the nozzle 80 described later include the humidity control unit 20, they can have a humidifying function that does not require water supply means. Also, a sufficient humidification function can be obtained. In addition, it has the property of absorbing moisture when the surrounding humidity is relatively high compared to its own equilibrium humidity, and releasing moisture when the surrounding becomes dry. Unlike desiccants such as A-type silica gel and zeolite, it absorbs and desorbs moisture repeatedly, so in principle it is effective semi-permanently. In addition, the humidity control section 20 is overwhelmingly superior in moisture control (humidification) moisture content to B-type silica gel, polymer sorbent material, inorganic mineral humidity control material, diatomaceous earth, and the like.

FIG. 1 is a cross-sectional view schematically showing the humidifying device according to the first embodiment. In FIG. 1, the air blown by the air blower 10 is blown leftward in the figure. As shown in FIG. 1 , the humidity control section 20 is provided in the air blowing path of the air blowing section 10 and housed in the main body section 30 . Also, in FIG. 1, the humidity control section 20 is provided in the upper part of the main body, but it may be provided in the air blowing path of the air blowing section 10, and may be in the lower part of the main body section 30. FIG. The humidity control section 20 may be downstream of the air blowing section 10 . Also, as shown in FIG. 1 , the humidity control unit 20 may be housed in the main body 30 .

Further, as shown in FIG. 1 , the humidifying device 100 according to the first embodiment preferably further includes a first heating section 40 that heats the air blown from the air blowing section 10 downstream of the air blowing section 10 . In this way, the first heating unit 40 heats the air blown from the air blowing unit 10 and heats the humidity control unit 20. Therefore, when the humidity control unit 20 releases moisture, the humidity control unit 20 More moisture can be released, and the humidifying function can be further enhanced. The first heating unit 40 and the second heating unit 45, which will be described later, only need to be able to heat the blower or humidity control unit 20, and examples thereof include electric heaters.

FIG. 2 is a perspective view schematically showing the humidity control section provided in the humidifying device. As shown in FIG. 2 , the humidity control section 20 has a humidity control material 21 . A plurality of humidity conditioning materials 21 may be stored in a storage member 28 such as a case.

FIG. 3 is a cross-sectional view taken along line III-III in FIG. As shown in FIG. 3, the humidity control unit 20 is provided with a ventilation hole 29 for absorbing and releasing moisture in the ambient air inside the main body. The ventilation hole 29 is formed in a bottom plate 28b that constitutes the storage member 28. As shown in FIG. Instead of forming the ventilation holes 29 in the storage member 28, or in addition to forming the ventilation holes 29 in the storage member 28, part or all of the storage member 28 may be configured with an air permeable membrane.

As shown in FIG. 3, the ventilation hole 29 is provided on the lower surface of the humidity control section 20, but the position is not limited as long as it can absorb moisture in the air inside the main body. For example, as shown in FIG. 3, a ventilation inlet W1 and a ventilation outlet W2 may be provided in a direction perpendicular to the air blown from the air blower 10 so that more air can be blown into the humidity control section 20 .

When the humidifying device 100 is not in operation, the humidity conditioning material 21 absorbs moisture in the ambient air through the ventilation holes 29 and/or the ventilation inlet W1 and ventilation outlet W2. On the other hand, when operating, the humidity conditioning material 21 releases moisture in the ambient air through the ventilation hole 29 and/or the ventilation outlet W2. In this way, the air blown from the air blower 10 is humidified.

Also, although the humidity conditioning material 21 shown in FIGS. 2 and 3 has one stage in the humidity conditioning section 20, it may have a plurality of stages. The humidity conditioning material 21 will be described in detail below.

FIG. 4 is a cross-sectional view schematically showing the humidity conditioning material 21 of the humidity conditioning section 20. As shown in FIG. The humidity conditioning material 21 preferably contains a resin 22 and a humidity conditioning liquid 23 impregnated in the resin 22 and having a humidity conditioning function of absorbing or releasing moisture. The humidity conditioning liquid 23 contained in the humidity conditioning material 21 absorbs and absorbs the moisture contained in the air in the place, or releases the moisture contained in the humidity conditioning material 21 into the air, depending on the humidity of the environment in which it is placed. Release and moisturize. The humidity-conditioning liquid contained in the humidity-conditioning liquid 23 releases moisture contained in the humidity-conditioning liquid 23 into the air even when heated.

The resin 22 has a function of retaining the humidity conditioning liquid 23 . Since the resin 22 holds the humidity conditioning liquid 23, the humidity conditioning material 21 having a high ratio of surface area to volume can be realized. Thus, the rate of moisture absorption or release can be increased. Therefore, it is possible to provide the humidity conditioning material 21 having a high humidity conditioning speed.

Specific examples of the resin 22 are preferably ionic resins and nonionic resins. Examples of the ionic resin include alkali metal salts of polyacrylic acid, starch-acrylate graft polymers, and the like. Specific examples of alkali metal salts of polyacrylic acid include sodium polyacrylate. Examples of nonionic resins include vinyl acetate copolymers, maleic anhydride copolymers, polyvinyl alcohols, polyalkylene oxides, and the like.

Also, the resin 22 is preferably a water absorbent resin. By doing so, the resin can be preferably impregnated with the humidity control liquid, and the humidifying effect can be further enhanced.

The humidity conditioning liquid 23 preferably contains at least one selected from the group consisting of deliquescent substances that absorb moisture in the air and deliquesce and polyhydric alcohols. By doing so, the moisture absorption function of the humidity control unit 20 is improved, so that the humidification effect can be further enhanced.

Specific examples of polyhydric alcohols include at least one selected from the group consisting of glycerin, propanediol, butanediol, pentanediol, trimethylolpropane, butanetriol, ethylene glycol, diethylene glycol, triethylene glycol, and lactic acid. Among them, polyhydric alcohols having 3 or more hydroxyl groups such as glycerin are more preferably used. In addition, the polyhydric alcohol may constitute a dimer or a polymer. Moreover, only 1 type may be included and 2 or more types may be included.

Deliquescent substances are classified into salts and water-soluble organic substances. Specific examples of salts include sodium formate, potassium formate, ammonium formate, sodium acetate, potassium acetate, lithium acetate, ammonium acetate, sodium lactate, potassium lactate, sodium benzoate, potassium benzoate, sodium propionate, and propionic acid. Potassium, calcium chloride, lithium chloride, magnesium chloride, calcium chloride, lithium chloride, potassium chloride, sodium chloride, zinc chloride, aluminum chloride, lithium bromide, calcium bromide, potassium bromide, sodium hydroxide, sodium pyrrolidonecarboxylate, Potassium carbonate, calcium citrate, sodium citrate, potassium citrate, lithium citrate and the like. Among these salts, only one kind may be contained, or two or more kinds may be contained. Among these, sodium formate, potassium formate, sodium acetate, potassium acetate, and potassium carbonate, which absorb and release moisture per weight, are preferred. Specific examples of water-soluble organic substances include sugars such as sucrose, pullulan, glucose, xylol, fructose, mannitol and sorbitol, carboxylic acids such as citric acid, and amides such as urea.

The amount of the humidity control liquid 23 with respect to the resin 22 is preferably 1 part by weight or more and 1000 parts by weight or less with respect to 100 parts by weight of the resin. By doing so, the amounts of the resin 22 and the humidity control liquid 23 are appropriate, and the humidifying and dehumidifying effects can be further enhanced.

The manufacturing method of the humidity conditioning material 21 shown in FIG. 4 includes a step of manufacturing the resin 22 and a step of swelling the obtained resin 22 with the humidity conditioning liquid 23 .

In the step of manufacturing the resin 22, the resin 22 can be manufactured by a known reverse phase suspension polymerization method. Specifically, the resin 22 has a continuous phase of a hydrophobic organic solvent containing a surfactant and a dispersant, and contains monomers constituting the repeating units of the above-described water-absorbing polymer material, a polymerization initiator, and a cross-linking agent. It can be produced by suspension polymerization using the mixed liquid containing the dispersed phase as the dispersed phase.

For example, acrylic acid, vinyl acetate, vinyl alcohol, and maleic anhydride can be used as monomers. As the polymerization initiator, for example, organic peroxides and azo compounds known as radical polymerization initiators can be used. A cross-linking agent is used to adjust the water absorption performance of the resin 22 obtained. The greater the amount of the cross-linking agent to be copolymerized with the monomer, the denser the cross-linking of the polymeric material forming the resin 22, and the lower the hygroscopicity. The smaller the amount of the cross-linking agent to be copolymerized with the monomer, the looser the cross-linking of the polymeric material forming the resin 22, and the more hygroscopic.

For the continuous phase organic solvent, for example, aliphatic hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons, aliphatic alcohols, aliphatic ketones, and aliphatic esters can be used.

The surfactant that can be used is not limited, and any of anionic surfactants, cationic surfactants, amphoteric surfactants and nonionic surfactants can be used.

The dispersant is not particularly limited, and any known dispersant can be used as long as it can stably disperse the monomer in the organic solvent. As the dispersant, for example, fatty acid ester, cellulose ether, cellulose ester, etc. can be used.

It is preferable to dry the resin 22 produced by the reversed-phase suspension polymerization method.

It should be noted that a structural color may be imparted to the resin 22 by inserting regularly arranged silica (colloidal crystals) during polymerization and removing the silica by etching or the like after polymerization. The structural color resin 22 can be produced in the same manner as a known method for producing an inverse opal gel.

In the step of swelling the resin 22 with the humidity conditioning liquid 23, the particulate resin 22 is immersed in the humidity conditioning liquid 23 described above and swelled. Thereby, the humidity conditioning material 21 can be manufactured.

The humidity conditioning material 21 shown in FIG. 4 may be in the form of particles of several millimeters to several tens of millimeters, or in the form of powder of several microns to several millimeters. Moreover, it is good also as a block shape.

Also, the humidity conditioning material 21 may further have a carrier that holds the resin 22 . The carrier has a function of holding the shape of the humidity conditioning material 21 . By having a carrier, the humidity conditioning material 21 can be formed into a sheet shape, and the sheet-shaped humidity conditioning material 21 may be used in the humidity conditioning section 20 . The humidity conditioning liquid 23 may also impregnate the carrier.

The mechanism by which the humidity conditioning material 21 absorbs and releases moisture will be described in detail below.

FIG. 5 is a diagram showing an example of the relationship between the moisture content and the equilibrium humidity in the humidity conditioning material 21. FIG. For example, when the environmental temperature and humidity of the ambient air are 25° C. and 60%, the humidity control material 21 absorbs moisture until it reaches the moisture content at equilibrium humidity of 60%. Then, when the humidifier 100 is in operation, for example, when the air around the humidity conditioning material 21 is warmed by air heated to 50° C., the relative humidity at 50° C. is 14%, so the humidity conditioning material 21 is in equilibrium. Air is blown from the humidifying device 100 and released to humidify until the water content reaches 14% humidity. Also, when the humidifier 100 is not in operation, the humidity conditioner 21 absorbs moisture again according to the humidity of the ambient air.

In this way, the humidity conditioning material 21 repeats moisture absorption and desorption by utilizing the difference between the relative humidity of the blown air and the relative humidity of the surrounding air. Then, the humidifying device 100 according to the present embodiment realizes a humidifying function using moisture in ambient air as a water source.

In addition, even in the configuration without the first heating unit and in the air blowing when the air is not heated by the first heating unit, the humidity control unit 20 is warmed by the heat when the air blowing unit 10 is operated, so even in such a case The humidity control unit 20 has a moisture release function.

In order to clearly show the wet state of the humidity conditioning material 21 in the humidity conditioning unit 20 using the above-described relative temperature and humidity differences, the humidity conditioning unit 20 changes color according to the wet state, as shown in FIGS. 6A and 6B. It is preferable to have a changing indicator. In this way, the difference in the moisture content at each equilibrium humidity can be indicated by the color change, so the moist state of the humidity control section 20 can be easily confirmed, and a sufficient humidification effect can be obtained. It can be expected that the humidification effect will be emphasized.

The indicator changes color based on the moisture content in the humidity conditioning liquid 23. When the humidity conditioning material 21 is provided with an indicator, the color of the humidity conditioning material 21 can change as the moisture content in the humidity conditioning liquid 23 changes as the relative humidity changes. Therefore, by confirming the color of the humidity conditioning material 21, the change in relative humidity can be confirmed. Note that the indicator may be dissolved in the humidity conditioning liquid 23, for example.

When indicating a dry state, the humidity conditioning material 21 may be colored as shown in FIG. 6A, and when indicating a wet state, the humidity conditioning material 21 may be colorless as shown in FIG. 6B. Also, depending on the type of indicator, the opposite can be done. Furthermore, in order to indicate the dry state and the wet state, the color of the indicator may be indicated by shading or may be indicated by hue change. The type of indicator may be changed as appropriate.

The indicator is not particularly limited, but may be a reversible pH indicator, cobalt chloride, or the like.

Preferred pH indicators include, for example, methyl purple, methyl yellow, bromophenol blue, congo red, methyl orange, bromocresol green, methyl red, litmus, bromocresol purple, bromothymol blue, phenol red, thymol blue, phenol phthalein, chlorophenol red, triarylmethane derivatives, fluorane derivatives, pyrazolone derivatives, azo derivatives, xanthene derivatives and the like.

The humidity conditioning material 21 may contain one type of indicator, but preferably contains multiple types of indicators. In this case, the plurality of types of indicators preferably include a plurality of types of indicators with mutually different pHs at which colors change. In this case, it is possible to increase the variation of colors that change with the change in pH of the humidity conditioning liquid 23 . Therefore, it is possible to check the relative humidity more strictly.

It is preferable that at least a portion of the storage member 28 constituting the humidity control section 20 has optical transparency so that the indicator can be visually recognized. In this way, it can be seen at a glance whether the humidity conditioning material 21 is in a dry state or a wet state.

As shown in FIG. 7, it is preferable that the humidity control unit 20 is provided with a plurality of layers 50 through which the air from the blower unit 10 is passed, and the humidity control material 21 is provided in each layer. In this way, the volume of the humidity control section 20 that receives air from the air blowing section 10 is increased, so that the humidification effect can be further enhanced. In addition, FIG. 7 is sectional drawing of the air-blowing direction.

In addition, it is preferable that the air-permeable base material 52 carries the humidity conditioning material 21 . Vent substrate 52 may be flexible or deformable. In other words, it may be possible to hold an arbitrary shape (a bent shape, a curved shape, etc.).

As the material for the ventilation base material 52, inorganic fibers, metal fibers, natural fibers, synthetic fibers, etc., or mixtures thereof are used. Examples of inorganic fibers include various inorganic materials such as glass, ceramics, and asbestos. Examples of metal fibers include various metals such as copper, SUS, and Al, inorganic fibers, natural fibers, synthetic fibers, and the like whose surface is coated (vapor-deposited) with metal. Synthetic fibers include thermoplastic resins such as polyolefin, polyester, polyamide, polyvinyl chloride, polycarbonate, polyvinyl alcohol, modified products and mixtures thereof. As the material of the ventilation base material 52, an inorganic plate, a resin plate, a metal plate, or a mixture thereof is used.

Further, even when the first heating unit 40 is provided in the humidifying device 110, the speed at which the humidity control unit 20 is heated is increased, and the humidifying effect can be improved.

Also, it is preferable that the temperature of the second heating unit 45 can be independently controlled. In this way, a desired amount of released moisture can be obtained.

As shown in FIG. 12, the humidifying device 130 according to the fourth embodiment preferably further includes a lid member 70 having a detachable water retaining material attached to the air outlet of the main body 30 or the nozzle 80 described below. The humidifying device 130 according to the fourth embodiment is configured to move the humidity control section 20 to a wet state at a higher speed or obtain a higher humidifying effect. This is suitable when it is desired to regenerate the humidity control section 20 more quickly, particularly when it is desired to obtain a greater humidifying effect even with cold air.

FIG. 13 is a diagram showing an example of the humidification effect when cold air is blown. As shown in FIG. 13, when the air is cold, the humidification effect is small because the relative temperature difference is small.
