Description

本発明は加湿器に関し、詳細には抗菌剤放出体を収納した水供給部を有する水槽を備えた加湿器に関する。   The present invention relates to a humidifier, and more particularly, to a humidifier equipped with a water tank having a water supply unit that houses an antibacterial agent emitter.

加湿器は、例えば吸水した水を蒸散させる加湿エレメントや、水を細かく粉砕して霧化させる超音波振動子等の加湿手段と、加湿手段に供給する加湿用水を貯留しておく水槽とを備えたものが一般に使用されている。   The humidifier includes, for example, a humidifying element that evaporates the absorbed water, humidifying means such as an ultrasonic vibrator that finely pulverizes and atomizes the water, and a water tank that stores humidifying water supplied to the humidifying means. Are commonly used.

水槽内に加湿用水が貯めた状態におかれると水槽内に混入した雑菌が繁殖して加湿用水が汚染され、加湿手段から雑菌が放出されて周辺の環境に悪影響を及ぼす場合がある。そのため、抗菌剤の使用により雑菌の繁殖を抑え、水槽の水を清浄に保つことが従来行われている。   If humidification water is stored in the water tank, the germs mixed in the water tank propagate and the humidification water is contaminated, and the germs are released from the humidification means, which may adversely affect the surrounding environment. For this reason, it has been conventionally practiced to use an antibacterial agent to suppress the propagation of germs and keep the water in the aquarium clean.

従来使用されている超音波加湿器の一例の概略側面断面図を図３に、概略平面図を図４に示す。   FIG. 3 is a schematic side sectional view of an example of a conventional ultrasonic humidifier, and FIG. 4 is a schematic plan view thereof.

超音波加湿器１００の水槽１０２内には、抗菌剤収納ケース１０４が配設され、抗菌剤収納ケース内には抗菌剤放出体１０６が収納されている。抗菌剤放出体１０６としては、多孔質セラミックスからなる球芯の外側に、１０質量％程度の銀を担持させた非多孔質セラミックスからなる外被を形成したものが使用される。外被の厚さは約０．５ｍｍで、抗菌剤放出体の平均粒径は約５ｍｍである。   An antibacterial agent storage case 104 is disposed in the water tank 102 of the ultrasonic humidifier 100, and an antibacterial agent emitter 106 is stored in the antibacterial agent storage case. As the antibacterial agent releasing body 106, an outer shell made of a porous ceramic and a jacket made of a non-porous ceramic carrying about 10% by mass of silver is used. The thickness of the jacket is about 0.5 mm, and the average particle diameter of the antimicrobial agent emitter is about 5 mm.

水槽内に水が貯留されると、水の解離により生成する水素イオンの作用により、抗菌剤放出体から少量の銀イオンが放出される。銀の抗菌作用自体は周知であり、細菌が銀イオンと接触することにより、殺菌や菌の増殖抑制などの抗菌効果がもたらされることが知られている。   When water is stored in the water tank, a small amount of silver ions is released from the antibacterial agent emitter by the action of hydrogen ions generated by the dissociation of water. The antibacterial action of silver itself is well known, and it is known that antibacterial effects such as sterilization and inhibition of bacterial growth are brought about by contact of bacteria with silver ions.

なお、図３及び図４中、１０８は水柱、１１０は霧、１１８はミキシングチャンバー、１２０は超音波振動子、１２２は振動子保持具、１２４は配線、１３２は収納ケース押え部材である。   3 and 4, 108 is a water column, 110 is fog, 118 is a mixing chamber, 120 is an ultrasonic vibrator, 122 is a vibrator holder, 124 is a wiring, and 132 is a storage case pressing member.

銀を抗菌剤に使用した加湿器の他の例としては、特許文献１に記載の銀を混練した樹脂ブロックが水槽内に配設された加湿器がある。
特開平５−１８０４７１号公報（段落番号００１２、００１６） As another example of a humidifier using silver as an antibacterial agent, there is a humidifier in which a resin block kneaded with silver described in Patent Document 1 is disposed in a water tank.
JP-A-5-180471 (paragraph numbers 0012 and 0016)

抗菌剤放出体を抗菌剤収納ケースに収めた加湿器を使用する場合、収納ケースの形状及び大きさに制限があるうえ、抗菌剤放出体が収納ケース内に集積して配置されるため、銀イオンの濃度が飽和に達しやすく、水に溶出する銀イオンの量が少なくなる。銀イオンの濃度は、収納ケースの内外で異なっており、特に収納ケースの外側で十分な抗菌効果を得ることができない。   When using a humidifier that contains an antibacterial agent emitter in an antibacterial agent storage case, the shape and size of the storage case are limited, and the antibacterial agent emitter is integrated and placed in the storage case. The concentration of ions tends to reach saturation, and the amount of silver ions eluted into water is reduced. The concentration of silver ions differs between the inside and outside of the storage case, and in particular, a sufficient antibacterial effect cannot be obtained outside the storage case.

特許文献１に記載の加湿器は、銀が混練してある樹脂ブロックを利用しており、表面に露出している銀の量が少なくなっている。そのため、銀の使用量に比較して水中に溶出する銀イオンが少なく、水槽内の加湿用水全体に対する高い抗菌効果は期待できない。   The humidifier described in Patent Document 1 uses a resin block in which silver is kneaded, and the amount of silver exposed on the surface is reduced. Therefore, there are few silver ions eluting in water compared with the usage-amount of silver, and the high antimicrobial effect with respect to the whole water for humidification in a water tank cannot be expected.

本発明の目的は、水槽内の水に混入した雑菌に対する抗菌効果が高い加湿器を提供することにある。   An object of the present invention is to provide a humidifier having a high antibacterial effect against various germs mixed in water in a water tank.

本発明者は鋭意研究を重ねた結果、表面が銀ゼオライト層で被覆された抗菌剤放出体を平板網状の収納袋に収納して加湿器の水槽内に載置し、抗菌剤放出体押え部材を用いて抗菌剤放出体を水没させた状態で加湿器を使用することにより、水中に高濃度の銀イオンが放出され、水槽全体にわたって高い抗菌効果が得られることを見出し、本発明を完成するに到った。   As a result of earnest research, the present inventor has stored the antibacterial agent emitter, the surface of which is coated with a silver zeolite layer, in a flat-plate-like storage bag and placed it in a water tank of a humidifier, and has the antibacterial agent emitter holding member By using a humidifier with the antibacterial agent emitter submerged in water, a high concentration of silver ions is released into the water, and a high antibacterial effect is obtained throughout the aquarium, completing the present invention.

本発明の加湿器の一例につき、図面を参照して以下詳細に説明する。図１は本発明の加湿器の概略側面断面図であり、図２は図１に示す加湿器の概略平面図である。   An example of the humidifier of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic side sectional view of the humidifier of the present invention, and FIG. 2 is a schematic plan view of the humidifier shown in FIG.

図１及び図２中、１は超音波加湿器である。超音波加湿器１は、上端が開放された略直方体状の水槽２を備えている。水槽２は、その下面両端に水槽を水平に支える支持部４及び６を有している。   1 and 2, reference numeral 1 denotes an ultrasonic humidifier. The ultrasonic humidifier 1 includes a substantially rectangular parallelepiped water tank 2 having an open upper end. The water tank 2 has support portions 4 and 6 that horizontally support the water tank at both ends of the lower surface thereof.

水槽２は、一対の対向する側壁８、１０に対して垂直に挿入された仕切り板１２により、霧発生部１４と、水供給部１６とに分けられる。仕切り板１２の下側には、霧発生部１４と水供給部１６とを連通する連通孔１８が形成されている。   The water tank 2 is divided into a mist generation unit 14 and a water supply unit 16 by a partition plate 12 inserted perpendicularly to a pair of opposing side walls 8 and 10. On the lower side of the partition plate 12, a communication hole 18 that connects the mist generation unit 14 and the water supply unit 16 is formed.

水供給部１６内の一端側には、水平板押え部材５８が水槽２の側壁と一体に形成されている。水平板押え部材５８の上方には水タンク６４が取り付けられている。水タンク６４の下端には内側に略円板状のバルブ６０を備えたキャップ６６が取り付けられている。水タンク６４を水槽２の所定位置に取り付ける際には、キャップ６６を貫通する棒状のバルブ支持部材６８の下端が水平板押え部材５８に接した後、水タンク５４の自重によりバルブ支持部材６８とバルブ６０が水タンク６４内に押し込まれる。これにより、バルブ６０が開き、水タンク５４内の加湿用水７０を給水口６２から水槽２内へ供給することが可能となる。   At one end side in the water supply unit 16, a horizontal plate pressing member 58 is formed integrally with the side wall of the water tank 2. A water tank 64 is attached above the horizontal plate holding member 58. At the lower end of the water tank 64, a cap 66 having a substantially disc-shaped valve 60 is attached inside. When the water tank 64 is attached to a predetermined position of the water tank 2, the lower end of the rod-shaped valve support member 68 that penetrates the cap 66 comes into contact with the horizontal plate holding member 58, and then the valve tank 68 The valve 60 is pushed into the water tank 64. Thereby, the valve 60 is opened, and the humidifying water 70 in the water tank 54 can be supplied into the water tank 2 from the water supply port 62.

水平板押え部材５８の一端側には、下方に向かって突き出した突出部５９が形成されている。水平板押え部材５８は、後述する抗菌剤放出体が収納された収納袋の浮上を抑制し、抗菌剤放出体の全てを水面下に水没させる。   A protruding portion 59 that protrudes downward is formed on one end side of the horizontal plate pressing member 58. The horizontal plate pressing member 58 suppresses the rising of a storage bag in which an antibacterial agent emitter to be described later is stored, and submerges all of the antibacterial agent emitter below the water surface.

水平板押え部材５８の下側には、抗菌剤放出体２６が収納された平板網状の樹脂製の収納袋２８が載置されている。収納袋の材質はポリエチレン、ポリプロピレン等であり、抗菌剤放出体２６は表面が銀ゼオライト層で被覆された平均粒径０．５〜１０ｍｍ、好ましくは１〜５ｍｍの粒子である。抗菌剤放出体２６は水中に浸漬されると銀イオンを放出し、抗菌効果を示す。   A flat-plate-shaped resin-made storage bag 28 in which the antibacterial agent releasing body 26 is stored is placed below the horizontal plate pressing member 58. The material of the storage bag is polyethylene, polypropylene, or the like, and the antibacterial agent emitter 26 is a particle having an average particle diameter of 0.5 to 10 mm, preferably 1 to 5 mm, whose surface is coated with a silver zeolite layer. When the antibacterial agent emitter 26 is immersed in water, it releases silver ions and exhibits an antibacterial effect.

霧発生部１４の下壁３０の中心部には、円板状の超音波振動子３２が絶縁弾性部材からなる振動子保持具３４を介して水平に取り付けられている。振動子３２は不図示の発振器と配線３６により電気的に接続されている。   A disc-shaped ultrasonic transducer 32 is horizontally attached to the center of the lower wall 30 of the fog generating unit 14 via a transducer holder 34 made of an insulating elastic member. The vibrator 32 is electrically connected to an oscillator (not shown) through a wiring 36.

霧発生部１４の対向側壁８、１０間には、側壁８、１０に対して垂直に２枚の四辺形状の板が離間して挿入され、チャンバー支持部材３８、４０を形成する。チャンバー支持部材３８、４０の下端は、水槽の下壁３０から離間されている。チャンバー支持部材３８、４０の上端には、中央にチャンバーの内径よりやや小径に形成された開口部４３を有する正方形状のチャンバー支持板４２が載置されている。チャンバー支持板４２上には、円筒形のミキシングチャンバー４４がその中心軸を水面に対して垂直にかつ振動子３２に一致させて載置されている。チャンバー４４の下側には、チャンバー４４の外周面に沿って１対のチャンバー固定部材４６、４８とが配置され、チャンバー４４と、チャンバー支持部材３８、４０とを固定している。図１中、５０、５２はチャンバー４４とチャンバー固定部材４６、４８とを固定するゴムパッキンである。   Two quadrilateral plates are inserted between the opposing side walls 8, 10 of the mist generation unit 14 perpendicularly to the side walls 8, 10 to form chamber support members 38, 40. The lower ends of the chamber support members 38 and 40 are separated from the lower wall 30 of the water tank. On the upper ends of the chamber support members 38 and 40, a square chamber support plate 42 having an opening 43 formed in the center with a diameter slightly smaller than the inner diameter of the chamber is placed. A cylindrical mixing chamber 44 is placed on the chamber support plate 42 with its central axis perpendicular to the water surface and coincident with the vibrator 32. A pair of chamber fixing members 46 and 48 are disposed below the chamber 44 along the outer peripheral surface of the chamber 44 to fix the chamber 44 and the chamber support members 38 and 40. In FIG. 1, reference numerals 50 and 52 denote rubber packings for fixing the chamber 44 and the chamber fixing members 46 and 48.

不図示の発振器から振動子３２に高周波電圧が印加されると、振動子３２がその固有振動数で振動して水槽２内の加湿用水に超音波が伝播する。振動子３２上方には、水が円錐状に盛り上がって水柱５４が形成され、ミキシングチャンバー４４内に水柱５４の先端が到達する。水柱５４の頂部では水が細かい粒子に粉砕されて霧５６が発生する。   When a high frequency voltage is applied to the vibrator 32 from an oscillator (not shown), the vibrator 32 vibrates at its natural frequency, and ultrasonic waves propagate to the humidifying water in the water tank 2. Above the vibrator 32, water rises in a conical shape to form a water column 54, and the tip of the water column 54 reaches the mixing chamber 44. At the top of the water column 54, water is crushed into fine particles, and a mist 56 is generated.

なお、水槽２、水平板押え部材５８等の形状や、振動子３２、ミキシングチャンバー４４、水タンク６４等の取り付け位置、取り付け数等は上記説明に限定されず、任意でよい。上記説明においては、仕切り板１２と水平板押え部材５８とを別々に形成した場合を示したが、これらは一体に形成されていてもよい。   Note that the shape of the water tank 2, the horizontal plate pressing member 58, the attachment positions and the number of attachments of the vibrator 32, the mixing chamber 44, the water tank 64, etc. are not limited to the above description, and may be arbitrary. In the above description, the case where the partition plate 12 and the horizontal plate pressing member 58 are separately formed is shown, but these may be formed integrally.

また、上記説明においては、加湿手段として超音波振動子を用いる場合について説明したが、加熱蒸発式、自然蒸発式等の他の加湿手段を用いてもよい。加湿手段の一例として、例えば特開2005-321184号公報記載の吸水した水を自然蒸発させる加湿エレメントを挙げることができる。   In the above description, the ultrasonic vibrator is used as the humidifying means. However, other humidifying means such as a heating evaporation type and a natural evaporation type may be used. As an example of the humidifying means, for example, a humidifying element described in Japanese Patent Application Laid-Open No. 2005-321184 can be given.

チャンバーの上端にはノズルが形成されていてもよい。所望により、気密に形成した水槽内に送風機等で外気を送り込んでチャンバー上端又はチャンバーに取り付けられたノズルから霧を吹き出させる構成の加湿器とすることもできる。   A nozzle may be formed at the upper end of the chamber. If desired, a humidifier having a configuration in which outside air is fed into an airtightly formed water tank by a blower or the like, and mist is blown out from a nozzle attached to the upper end of the chamber or the chamber.

抗菌剤放出体２６の銀ゼオライト層はゼオライトに銀イオンを吸着させてなる銀ゼオライト粒子で形成される。銀ゼオライト粒子の好ましい平均粒径は０．５〜２μｍであり、より好ましくは０．８〜１．５μｍである。銀ゼオライト層の平均厚さは１０〜７００μｍが好ましく、１００〜５００μｍがより好ましい。抗菌剤放出体の芯材としては、ポリエチレン粒子等を挙げることができる。   The silver zeolite layer of the antibacterial agent emitter 26 is formed of silver zeolite particles obtained by adsorbing silver ions on zeolite. A preferable average particle diameter of the silver zeolite particles is 0.5 to 2 μm, and more preferably 0.8 to 1.5 μm. The average thickness of the silver zeolite layer is preferably 10 to 700 μm, more preferably 100 to 500 μm. Examples of the core material of the antibacterial agent emitter include polyethylene particles.

銀ゼオライトは、例えば、細孔内にナトリウムイオンを吸着させたＡ型ゼオライト粒子を硝酸銀に浸漬させ、ナトリウムイオンを銀イオンにイオン交換することにより製造できる。この方法により得られた銀ゼオライトの組成は、(SiO2)12(AlO2)- 12・Ag+ 12・(H2O)27である。銀ゼオライトで表面を被覆した抗菌剤放出体を水中に浸漬した場合には、ゼオライトの細孔内に吸着した銀イオンが水中に放出される。従って、銀を担持させた非多孔質セラミックスを外被に有する従来の抗菌剤放出体を使用する場合に比較して高濃度の銀イオンを水中に放出させることができ、水槽全体において高い抗菌効果を得ることができる。 Silver zeolite can be produced, for example, by immersing A-type zeolite particles in which sodium ions are adsorbed in pores in silver nitrate, and ion-exchanging sodium ions to silver ions. The composition of silver zeolite obtained by this method, (SiO 2) 12 (AlO 2) - a 12 · Ag + 12 · (H 2 O) 27. When an antibacterial agent emitter whose surface is coated with silver zeolite is immersed in water, silver ions adsorbed in the pores of the zeolite are released into the water. Therefore, compared to the case of using a conventional antibacterial agent emitter that has a non-porous ceramic with a silver supported on the outer shell, it is possible to release a high concentration of silver ions into the water, resulting in a high antibacterial effect throughout the tank. Can be obtained.

抗菌剤放出体の収納量は、水槽の最大貯水量の５〜１０質量％程度とすることが好ましく、６〜８質量％とすることがより好ましい。   The storage amount of the antibacterial agent emitter is preferably about 5 to 10% by mass, and more preferably 6 to 8% by mass of the maximum water storage amount of the water tank.

実施例１
図１及び図２に示す超音波加湿器の水槽（９２ｍｍ×２５０ｍｍ×１２０ｍｍ）に水を入れ、２４時間放置した。その後、水槽内の水の細菌数を計測したところ３０個／ｃｍ3以下（検知せず）だった。水供給部の容積は０．７５Ｌ、霧発生部の容積は０．７５Ｌである。抗菌剤放出体にはポリエチレン樹脂を銀ゼオライトで被覆した平均粒径３ｍｍの粒子を用い、平板網状に形成された樹脂製収納袋に７５ｇを充填して使用した。加湿器を２４時間運転後、加湿器から放出される霧に含まれる細菌数を計測したところ、３０個／ｃｍ3以下（検知せず）であった。 Example 1
Water was put into the water tank (92 mm × 250 mm × 120 mm) of the ultrasonic humidifier shown in FIGS. 1 and 2 and left for 24 hours. Thereafter, the number of bacteria in the water in the water tank was measured and found to be 30 / cm 3 or less (not detected). The volume of the water supply unit is 0.75 L, and the volume of the fog generating unit is 0.75 L. As the antibacterial agent releasing body, particles having an average particle diameter of 3 mm coated with a silver resin with a polyethylene resin were used by filling 75 g in a resin storage bag formed in a flat mesh shape. After the humidifier was operated for 24 hours, the number of bacteria contained in the mist discharged from the humidifier was measured and found to be 30 / cm 3 or less (not detected).

比較例１
抗菌剤放出体として、多孔質セラミックを厚さ０．５ｍｍの１０質量％の銀を担持させた非多孔質セラミックで被覆した平均粒径５ｍｍのセラミック銀（長野セラミックス社製）を使用した以外は実施例１と同じ加湿器を使用した。実施例１と同様に細菌数を計測したところ、１００００個／ｃｍ3であった。 Comparative Example 1
