Description

本発明は、ミスト流路カバーを通じて外部空間にミストを吐出するミスト吐出装置に関する。   The present invention relates to a mist discharge device that discharges mist to an external space through a mist flow path cover.

ミスト発生手段で発生させた高温のミストを外部空間に吐出することで、肌表面の手入れ等を行うことのできるミスト吐出装置が知られている。上記ミスト吐出装置においては、ミスト発生手段を内蔵する装置本体からパイプ状のミスト流路カバーを延設し、この長尺のミスト流路カバーを通じて、高温のミストを適温にまで低下させたうえで顔面等の狙いの部位に対して正確に当てるようになっている（特許文献１参照）。   2. Description of the Related Art There is known a mist ejecting device that can clean the surface of a skin by ejecting high temperature mist generated by a mist generating means to an external space. In the mist discharge device, a pipe-shaped mist flow path cover is extended from the apparatus main body containing the mist generating means, and the high temperature mist is lowered to an appropriate temperature through the long mist flow path cover. It is designed to be accurately applied to a target site such as the face (see Patent Document 1).

ところが、上記のミスト流路カバーを有するミスト吐出装置においては、ミスト流路カバーの全長が長いために装置全体のスペースが大きくなり、使用者にとっては収納しづらいという問題がある。この問題を解決するためには、ミスト流路カバーを短くした構造にすることが考えられる。   However, in the mist discharge device having the mist flow path cover described above, the entire length of the mist flow path cover is long, so that there is a problem that the space of the entire apparatus becomes large and it is difficult for the user to store. In order to solve this problem, it is conceivable to make the mist flow path cover short.

しかし、上記構造にした場合には、外部空間に向けてミストを吐出させる吐出口が、装置本体内のミスト発生手段に近づくことになる。このため、吐出口から吐出させた直後のミスト温度が高くなり、使用者が顔面等の狙いの部位を吐出口に接近させることが困難になる。吐出口と狙いの部位との間に距離ができると、吐出口から吐出されたミストが狙いの部位に到達するまでの間に拡散してしまい、顔面等の狙いの部位にむけてミストを正確に当てづらくなるという問題が生じる。
特開２００７−２６００５８号公報 However, in the case of the above structure, the discharge port for discharging mist toward the external space approaches the mist generating means in the apparatus main body. For this reason, the mist temperature immediately after discharging from the discharge port becomes high, and it becomes difficult for the user to bring the target site such as the face close to the discharge port. If there is a distance between the discharge port and the target part, the mist discharged from the discharge port will diffuse before reaching the target part, and the mist will be accurately directed toward the target part such as the face. The problem arises that it becomes difficult to apply to.
JP 2007-260058 A

本発明は上記問題点に鑑みて発明したものであって、ミスト流路カバーの全長を長くせずとも、ミスト温度を適温にまで低下させたうえで、狙いの部位にむけて正確に吐出することのできるミスト吐出装置を提供することを課題とするものである。   The present invention has been invented in view of the above-described problems, and accurately discharges toward a target site after reducing the mist temperature to an appropriate temperature without increasing the overall length of the mist flow path cover. It is an object of the present invention to provide a mist discharge device that can perform the above operation.

上記課題を解決するために本発明を、ミスト発生手段及びミスト流路部１９を内蔵する装置本体２と、装置本体２から延出したパイプ状のミスト流路カバー３とを具備し、ミスト発生手段で発生させた高温のミストを、ミスト流路部１９を通じてミスト流路カバー３内に送り込むとともに該ミスト流路カバー３の吐出口５を通じて外部空間に吐出するミスト吐出装置において、ミスト流路部２９の下流端開口にミスト流路カバー３の上流端が連通するように設け、ミスト発生手段から送り込まれたミストを下流側に勢いよく噴出させる筒状の絞り部２１を、このミスト流路部２９の下流端開口に装着し、ミスト流路カバー３内の負圧によって該ミスト流路カバー３内に外気を引き込む外気導入路２３を、パイプ状のミスト流路カバー３の側周壁に貫設することで、適温のミストを外部空間の狙いの部位にむけて放出するように設けたものとする。 In order to solve the above-mentioned problems, the present invention comprises a device main body 2 incorporating a mist generating means and a mist flow channel portion 19 and a pipe-shaped mist flow channel cover 3 extending from the device main body 2 to generate mist. hot mist which is generated by means, in the mist ejection device which ejects to the outside space through the discharge port 5 of the mist flow path cover 3 together sent into the mist passage cover 3 through the mist passage 19, the mist flow path portion provided to the upstream end of the mist passage cover 3 to the downstream end opening 29 is communicated, the cylindrical narrowed portion 21 momentum to well eject the mist fed from the mist generation unit on the downstream side, the mist flow path portion The outside air introduction passage 23 that is attached to the downstream end opening 29 and draws the outside air into the mist passage cover 3 by the negative pressure in the mist passage cover 3 is connected to the side periphery of the pipe-like mist passage cover 3. A By pierced, and that provided to emit toward the mist of suitable temperature to the site of aim of outer space.

このようにすることで、ミスト流路カバー３内にミストが流れると、ミスト流路カバー３内で生じる負圧によって外気導入路２３を通じて該ミスト流路カバー３内に外気が導入される。ミスト流路カバー３内に導入された外気は、ミストの流れに沿ってミスト流路カバー３内を流れ、吐出口５を通じてミストと共に外部空間に放出される。このとき、導入された外気によってミストの温度が下げられるので、ミスト流路カバー３の全長を長く設けずとも、吐出口５からは適温のミストが放出されるようになる。加えて、導入された外気の流れは、ミスト流路カバー３内でミストの流れが生じさせる乱流を整流するように働くので、ミスト流路カバー３の全長を長く設けずとも、吐出口５からはミストが良好な直進性を持って吐出されることになる。つまり、本発明のミスト吐出装置によれば、ミスト流路カバー３の全長を長くせずとも、ミスト流路カバー３に開口を設けたシンプルな構造により、ミスト温度を適温にまで低下させたうえで、脈動やゆらぎを生じることなく狙いの部位にむけて正確に吐出することができる。また、上記構成のミスト吐出装置にあっては、ミスト発生手段から送り込まれたミストを下流側に勢いよく噴出させる絞り部２１が、ミスト流路カバー３内における外気導入路２３との連通部分よりも上流側のミスト流路Ｓ中に配置される。したがって、ミストを外部の狙いの部位に向けて勢い良く噴出することができるとともに、ミストの噴出の勢いによって、外気導入路２３を通じて外気を導入するための負圧を効果的に生じさせることができる。したがって、ミストの噴出量は増えるものの、外気の導入量も増大するためにミストの温度を適温に保つことやミストの直進性を保つことができる。つまり、適温のミストを、狙いの部位に向けて高い直進性を保ちながら、勢いよく噴出することが可能となる。 In this way, when mist flows in the mist flow path cover 3, the external air is introduced into the mist flow path cover 3 through the external air introduction path 23 due to the negative pressure generated in the mist flow path cover 3. The outside air introduced into the mist flow path cover 3 flows in the mist flow path cover 3 along the flow of mist, and is discharged to the external space together with the mist through the discharge port 5. At this time, since the temperature of the mist is lowered by the introduced outside air, the mist having an appropriate temperature is discharged from the discharge port 5 without providing the entire length of the mist flow path cover 3 long. In addition, since the flow of the introduced outside air works to rectify the turbulent flow generated by the mist flow in the mist flow path cover 3, the discharge port 5 can be provided without providing the full length of the mist flow path cover 3. The mist is discharged with good straightness. That is, according to the mist discharge device of the present invention , the mist temperature is reduced to an appropriate temperature by a simple structure in which an opening is provided in the mist flow path cover 3 without increasing the overall length of the mist flow path cover 3. Thus, the liquid can be accurately discharged toward the target portion without causing pulsation or fluctuation. Further, in the mist discharge device having the above-described configuration, the throttle portion 21 that vigorously ejects the mist fed from the mist generating means to the downstream side from the communicating portion with the outside air introduction path 23 in the mist flow path cover 3. Is also disposed in the upstream mist channel S. Accordingly, the mist can be ejected vigorously toward an external target site, and the negative pressure for introducing the outside air through the outside air introduction path 23 can be effectively generated by the mist ejection force. . Therefore, although the amount of mist ejected increases, the amount of outside air introduced also increases, so that the temperature of the mist can be maintained at an appropriate temperature and the straightness of the mist can be maintained. That is, it becomes possible to spout the mist of the appropriate temperature vigorously while maintaining high straightness toward the target site.

また、ミスト流路カバー３内における外気導入路２３との連通部分を、ミスト流路カバー３の吐出口５側からみて絞り部２１を囲む配置で形成することも好適である。このようにすることで、ミスト流路カバー３内に導入された外気の流れを、絞り部２１から噴出されるミストの流れを囲むように形成することができる。したがって、導入した外気によってミストの流れを効果的に整流することが可能となる。   In addition, it is also preferable to form a communication portion with the outside air introduction path 23 in the mist flow path cover 3 so as to surround the throttle portion 21 when viewed from the discharge port 5 side of the mist flow path cover 3. By doing in this way, the flow of outside air introduced into the mist flow path cover 3 can be formed so as to surround the flow of mist ejected from the throttle portion 21. Therefore, the flow of mist can be effectively rectified by the introduced outside air.

請求項１に係る発明は、ミスト流路カバーの全長を長くせずとも、ミスト温度を適温にまで低下させたうえで、脈動やゆらぎを生じることなく狙いの部位にむけて正確に吐出することができるという効果や、適温のミストを、狙いの部位に向けて高い直進性で勢いよく噴出させることができるという効果や、外気を導入するための構造をシンプルに形成することができるという効果を奏する。 According to the first aspect of the present invention, the mist temperature is reduced to an appropriate temperature without increasing the overall length of the mist flow path cover, and the mist flow path cover is accurately discharged toward the target site without causing pulsation or fluctuation. The effect of being able to shoot, the effect of being able to expel the right temperature mist toward the target site with high straightness and vigorously, and the effect of being able to simply form a structure for introducing outside air Play.

また請求項２に係る発明は、請求項１に係る発明の効果に加えて、ミスト流路カバー内に導入した外気によって、ミストの流れを効果的に整流することができるという効果を奏する。 The invention according to claim 2, in addition to the effect of the invention according to claim 1, the outside air introduced into the mist passage in the cover, there is an effect that it is possible to effectively rectify the flow of the mist.

以下、本発明を添付図面に示す実施形態に基づいて説明する。まず、図１、図２には、第１の比較例であるミスト吐出装置の全体を示している。 Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. First, FIG. 1 and FIG. 2 show the whole of a mist discharge device as a first comparative example .

本例のミスト吐出装置は、沸騰室１から成るミスト発生手段を内蔵する装置本体２と、装置本体２から延出した形で該装置本体２に装着するパイプ状のミスト流路カバー３と、装置本体２に着脱自在に装着される貯水タンク４とを具備している。ミスト流路カバー３は、下流側ほど径が増大する形状である。そして、沸騰室１内で発生させた高温のミスト（本例ではスチーム）をミスト流路カバー３内へと送り込み、ミスト流路カバー３の下流端の吐出口５を通じて、外部空間にミストを吐出するようになっている。適温のミストを使用者の顔面等の狙いの部位に当てることで、美容効果を得ることができる。   The mist discharge device of this example includes a device main body 2 containing a mist generating means composed of a boiling chamber 1, a pipe-like mist flow path cover 3 attached to the device main body 2 in a form extending from the device main body 2, A water storage tank 4 is detachably attached to the apparatus main body 2. The mist flow path cover 3 has a shape whose diameter increases toward the downstream side. Then, high-temperature mist (steam in this example) generated in the boiling chamber 1 is fed into the mist flow path cover 3 and discharged through the discharge port 5 at the downstream end of the mist flow path cover 3 to the external space. It is supposed to be. A cosmetic effect can be obtained by applying an appropriate temperature mist to a target site such as a user's face.

上記装置本体２は、複数のパーツを組み合わせて成る本体ハウジング６内に、水を沸騰させて高温のミストを発生させる沸騰室１と、貯水タンク４内に貯留される水を沸騰室１にまで順次供給する給水機構７と、沸騰室１内の水を沸騰させる熱源となるヒータ１７と、沸騰室１で発生したミストを外部空間に向けて吐出させるミスト吐出機構８とを備えている。   The apparatus main body 2 includes a boiling chamber 1 in which water is boiled to generate high-temperature mist in a main body housing 6 formed by combining a plurality of parts, and water stored in the water storage tank 4 is supplied to the boiling chamber 1. A water supply mechanism 7 that supplies water sequentially, a heater 17 that serves as a heat source for boiling water in the boiling chamber 1, and a mist discharge mechanism 8 that discharges mist generated in the boiling chamber 1 toward the external space are provided.

上記給水機構７は、貯水タンク４に設けてある止水ピン９を持ち上げて該貯水タンク４の水密状態を解除する解除ピン１０と、貯水タンク４から供給された水を貯留させる給水貯留部１１と、給水貯留部１１の下流端から斜め下方に延設される第１給水路１３と、第１給水経路の下流端から略鉛直上方に延設される第２給水路１４と、第２給水路１４の上端部を沸騰室１に連通させる連通路１５とで形成している。更に、第１給水路１３の流路途中から略鉛直上方に向けて、予備加熱経路部１６を延設している。予備加熱経路部１６の上端部は、後述のミスト発生部１８に連通させている。   The water supply mechanism 7 includes a release pin 10 that lifts a water stop pin 9 provided in the water storage tank 4 to release the watertight state of the water storage tank 4, and a water supply storage unit 11 that stores water supplied from the water storage tank 4. A first water supply path 13 extending obliquely downward from the downstream end of the water supply storage section 11, a second water supply path 14 extending substantially vertically upward from the downstream end of the first water supply path, and a second water supply The upper end of the passage 14 is formed by a communication passage 15 that communicates with the boiling chamber 1. Further, a preheating path portion 16 is extended from the middle of the first water supply path 13 substantially vertically upward. The upper end portion of the preheating path portion 16 is in communication with a mist generating portion 18 described later.

上記ヒータ１７は、その加熱面１７ａを沸騰室１に対向させるとともに、その放熱面１７ｂを予備加熱経路部１６に対向させて設けている。つまり、上記ヒータ１７は、沸騰室１内で水を沸騰させるための熱源であるとともに、沸騰室１に供給される前段階の水に予熱を与えるための熱源でもある。   The heater 17 is provided with its heating surface 17 a facing the boiling chamber 1 and its heat radiating surface 17 b facing the preheating path section 16. That is, the heater 17 is a heat source for boiling water in the boiling chamber 1 and also a heat source for preheating water in the previous stage supplied to the boiling chamber 1.

上記ミスト吐出機構８は、沸騰室１に連通するミスト発生部１８と、ミスト発生部１８から延設されるパイプ状のミスト流路部１９とから成る。ミスト流路部１９の流路途中には、ミストを微細化するための高圧放電装置２０を配置している。また、ミスト流路部１９の下流端開口には、該ミスト流路部１９に比して小径の絞り部２１を装着しており、ミスト発生部１８からミスト流路部１９を通じて送り込まれたミストを、この筒状の絞り部２１を通じて下流側に向けて（即ち、外部空間に向けて）勢いよく噴出させるように設けている。   The mist discharge mechanism 8 includes a mist generator 18 that communicates with the boiling chamber 1 and a pipe-like mist channel 19 that extends from the mist generator 18. In the middle of the flow path of the mist flow path portion 19, a high-pressure discharge device 20 for miniaturizing the mist is disposed. A squeezed portion 21 having a diameter smaller than that of the mist channel portion 19 is attached to the downstream end opening of the mist channel portion 19, and the mist fed from the mist generating portion 18 through the mist channel portion 19. Is ejected vigorously toward the downstream side (that is, toward the external space) through the cylindrical throttle portion 21.

装置本体２の本体ハウジング６の上部には、ミスト流路部１９の下流端および絞り部２１を本体ハウジング６から露出させるように開口部２２を設けている。上記ミスト流路カバー３は、上記開口部２２に嵌め込む形で本体ハウジング６に装着しており、上記ミスト流路カバー３と上記ミスト流路部１９とで、発生したミストを外部空間に吐出させる一連のミスト流路Ｓを形成している。   In the upper part of the main body housing 6 of the apparatus main body 2, an opening 22 is provided so as to expose the downstream end of the mist flow path portion 19 and the throttle portion 21 from the main body housing 6. The mist flow path cover 3 is attached to the main body housing 6 so as to be fitted into the opening 22, and the mist generated by the mist flow path cover 3 and the mist flow path portion 19 is discharged to the external space. A series of mist channels S to be formed is formed.

そして、本例のミスト吐出装置にあっては、ミストを吐出させる際にミスト流路カバー３内で生じる負圧を利用して該ミスト流路カバー３内に外気を引き込むように、ミスト流路カバー３内の流路途中と外部空間とをつなぐ外気導入路２３を、ミスト流路Ｓとは別流路で形成している。   In the mist discharge device of this example, the mist flow path is drawn so as to draw the outside air into the mist flow path cover 3 using the negative pressure generated in the mist flow path cover 3 when discharging the mist. An outside air introduction path 23 connecting the middle of the flow path in the cover 3 and the external space is formed as a flow path different from the mist flow path S.

具体的には、ミスト流路部１９の下流端部と、該下流端部を覆うミスト流路カバー３との接続部分に、所定の隙間２４を設けている。そして、この隙間２４を通じて、ミスト流路カバー３内のミスト流路Ｓと、本体ハウジング６の内部空間とを連通させている。本体ハウジング６を成す複数のパーツ間には一定の隙間が設けてあり、本体ハウジング６の内部空間は、上記パーツ間の隙間を通じて外部空間と連通している。   Specifically, a predetermined gap 24 is provided at a connection portion between the downstream end portion of the mist flow path portion 19 and the mist flow path cover 3 covering the downstream end portion. The mist flow path S in the mist flow path cover 3 and the internal space of the main body housing 6 are communicated with each other through the gap 24. A certain gap is provided between a plurality of parts constituting the main body housing 6, and the internal space of the main body housing 6 communicates with the external space through the gap between the parts.

即ち、本例の外気導入路２３は装置本体２側に形成したものであって、本体ハウジング６を成す複数のパーツ間の隙間を外気流入口とし、本体ハウジング６の内部空間を主流路とし、ミスト流路部１９の下流端とミスト流路カバー３との隙間２４を外気流出口としている。   That is, the outside air introduction path 23 of this example is formed on the apparatus main body 2 side, and a gap between a plurality of parts constituting the main body housing 6 is an external air flow inlet, and an internal space of the main body housing 6 is a main flow path. A gap 24 between the downstream end of the mist flow path portion 19 and the mist flow path cover 3 is used as an external air flow outlet.

上記構成から成る本例のミスト吐出装置において、貯水タンク４から給水機構７を通じて沸騰室１に供給された水を沸騰させてミスト発生部１８内に高温のミストを発生させると、発生したミストはミスト流路部１９内を流れて高圧放電装置２０により微細化されたうえで、小径の絞り部２１を通じて勢いよく噴出される（図３中の矢印Ａ参照）。このとき、ミスト流路カバー３内においては、ミストが噴出されることによるベンチュリ効果によって、外気導入路２３を通じてミスト流路カバー３内に外気が導入される（図３中の矢印Ｂ参照）。   In the mist discharge device of the present example having the above-described configuration, when the water supplied from the water storage tank 4 to the boiling chamber 1 through the water supply mechanism 7 is boiled to generate high-temperature mist in the mist generating unit 18, the generated mist is After flowing through the mist channel 19 and being miniaturized by the high-pressure discharge device 20, it is ejected vigorously through the narrow-diameter restrictor 21 (see arrow A in FIG. 3). At this time, outside air is introduced into the mist passage cover 3 through the outside air introduction passage 23 by the venturi effect caused by the ejection of mist in the mist passage cover 3 (see arrow B in FIG. 3).

ミスト流路カバー３内に導入された外気は、ミストの流れに沿ってミスト流路カバー３内を流れ、吐出口５を通じてミストと共に外部空間に放出される。このとき、導入された外気によってミストの温度が下げられることで、吐出口５からは適温のミストが放出されるようになる。加えて、導入された外気の流れは、絞り部２１から勢いよく噴出するミストがミスト流路カバー３内で発生させる乱流を整流するようにも働く。つまり、ミスト流路カバー３を長尺に設けずとも、吐出口５からは適温のミストが、脈動やゆらぎを生じることなく良好な直進性を持って吐出されることになる。   The outside air introduced into the mist flow path cover 3 flows in the mist flow path cover 3 along the flow of mist, and is discharged to the external space together with the mist through the discharge port 5. At this time, the temperature of the mist is lowered by the introduced outside air, so that the mist having an appropriate temperature is discharged from the discharge port 5. In addition, the flow of the introduced outside air also works to rectify the turbulent flow generated in the mist flow path cover 3 by the mist ejected vigorously from the throttle portion 21. That is, even if the mist flow path cover 3 is not provided long, mist having an appropriate temperature is discharged from the discharge port 5 with good straightness without causing pulsation or fluctuation.

特に本例では、ミストを勢いよく噴出させる絞り部２１を、ミスト流路カバー３内の隙間２４（つまり、ミスト流路カバー３内における外気導入路２３との連通部分）よりも上流側に配置している。したがって、外気導入路２３を通じてミスト流路カバー３内に外気を引き込むための負圧を、ミスト流路カバー３内の隙間２４近傍において効果的に生じさせることができる。   In particular, in this example, the throttle portion 21 that ejects mist vigorously is disposed upstream of the gap 24 in the mist flow path cover 3 (that is, the communication portion with the outside air introduction path 23 in the mist flow path cover 3). is doing. Therefore, a negative pressure for drawing the outside air into the mist channel cover 3 through the outside air introduction path 23 can be effectively generated in the vicinity of the gap 24 in the mist channel cover 3.

また、本例では、ミスト流路カバー３内の隙間２４を、ミスト流路カバー３の吐出口５側からみたときに絞り部２１をぐるりと囲む配置で形成している。上記隙間２４の配置としては、絞り部２１を中心に描く円周上において略等間隔を隔てて複数の隙間２４を隣接させる配置であってもよいし、或いは、図４に概略的に示すように隙間２４をリング状に形成してもよい。上記配置により、ミストが発生させる乱流を、該ミストを囲むようにミスト流路カバー３内で形成される外気の流れによって、効果的に整流することができる。なお、上記隙間２４の開口幅は１ｍｍ以上であることが好ましい。   Further, in this example, the gap 24 in the mist flow path cover 3 is formed so as to surround the throttle portion 21 when viewed from the discharge port 5 side of the mist flow path cover 3. The arrangement of the gaps 24 may be an arrangement in which a plurality of gaps 24 are adjacent to each other at substantially equal intervals on the circumference drawn around the narrowed portion 21, or as schematically shown in FIG. Alternatively, the gap 24 may be formed in a ring shape. With the above arrangement, the turbulent flow generated by the mist can be effectively rectified by the flow of outside air formed in the mist flow path cover 3 so as to surround the mist. The opening width of the gap 24 is preferably 1 mm or more.

次に、第２の比較例であるミスト吐出装置について、図５に基づいて説明する。なお、本例の基本的な構成は第１の比較例と同様であるため、以下においては、概略図に基づいて本例の特徴的な構成についてのみ詳述する。 Next, a mist ejection device as a second comparative example will be described with reference to FIG. Since the basic configuration of this example is the same as that of the first comparative example, only the characteristic configuration of this example will be described in detail below based on the schematic diagram.

本例のミスト吐出装置においては、装置本体２内に形成される外気導入路２３を、第１例のように本体ハウジング６の内部空間全体を利用して形成するのではなく、本体ハウジング６内に外気導入用の専用の流路を形成している点に特徴を有している。図示例の外気導入路２３は、本体ハウジング６内に一対形成したものであり、一方の外気導入路２３はその上流端の外気流入口を本体ハウジング６の頂部に末広がりで開口させ、他方の外気導入路２３はその上流端の外気流入口を本体ハウジング６の底部に末広がりで開口させている。   In the mist discharge device of this example, the outside air introduction path 23 formed in the device main body 2 is not formed using the entire internal space of the main body housing 6 as in the first example, but in the main body housing 6. Is characterized in that a dedicated flow path for introducing outside air is formed. In the illustrated example, a pair of outside air introduction paths 23 are formed in the main body housing 6, and one outside air introduction path 23 has an outside air flow inlet at its upstream end opened to the top of the main body housing 6 so as to widen toward the other end, and the other outside air introduction path 23. The introduction path 23 has an external air flow inlet at its upstream end opened to the bottom of the main body housing 6 so as to spread outward.

このように本体ハウジング６側に専用の外気導入路２３を設け、専用の外気流入口を本体ハウジング６に開口させて設けることで、多くの外気を効率的に導入することが可能となる。なお、外気導入路２３の数や形状等は図示例に限定されず、外気導入路２３の外気流入口の位置についても他の位置で構わない。   As described above, by providing the dedicated external air introduction path 23 on the main body housing 6 side and providing the dedicated external air flow inlet to the main body housing 6, a large amount of external air can be efficiently introduced. The number, shape, and the like of the outside air introduction path 23 are not limited to the illustrated example, and the position of the outside air inlet of the outside air introduction path 23 may be another position.

次に、本発明の実施形態における一例のミスト吐出装置について、図６に基づいて説明する。なお、本例の基本的な構成は第１の比較例と同様であるため、以下においては、概略図に基づいて本例の特徴的な構成についてのみ詳述する。 Next, an example mist discharge device in the embodiment of the present invention will be described with reference to FIG. Since the basic configuration of this example is the same as that of the first comparative example, only the characteristic configuration of this example will be described in detail below based on the schematic diagram.

本例のミスト吐出装置においては、装置本体２内に形成される外気導入路２３を、第１例のように本体ハウジング６側に形成するのではなく、ミスト流路カバー３側に形成している点に特徴を有している。図示例の外気導入路２３は、パイプ状のミスト流路カバー３の側周壁を貫設したものであり、外気導入路２３の外部空間に連通する部分が外気流入口となり、外気導入路２３のミスト流路カバー３内に連通する部分が外気流出口となっている。   In the mist discharge device of this example, the outside air introduction path 23 formed in the apparatus main body 2 is not formed on the main body housing 6 side as in the first example, but is formed on the mist flow path cover 3 side. It has a feature in that. The illustrated outside air introduction path 23 is formed by penetrating the side peripheral wall of the pipe-shaped mist passage cover 3, and a portion communicating with the external space of the outside air introduction path 23 serves as an outside air inlet. A portion communicating with the mist flow path cover 3 is an external air flow outlet.

図６（ａ）には、外気導入路２３を、ミスト流路カバー３の側周壁のうちで根本側の小径部分に貫設した場合を示している。また、図６（ｂ）には、外気導入路２３を、ミスト流路カバー３の側周壁の略全体に亘って貫設した場合を示している。   FIG. 6A shows a case where the outside air introduction path 23 is provided in a small-diameter portion on the root side in the side peripheral wall of the mist flow path cover 3. FIG. 6B shows a case where the outside air introduction path 23 is provided through substantially the entire side peripheral wall of the mist flow path cover 3.

ミスト流路カバー３に設ける外気導入路２３の数や形状等は特に制限されないが、外気導入路２３を、その上流側に絞り部２１が位置するように設けることや、吐出口５側からみて絞り部２１を囲むような配置に設けることが好ましい。外気導入路２３の開口幅は０．５ｍｍ以上とすることが好ましく、また、開口幅を２ｍｍ以上とすることが更に好ましい。   The number, shape, and the like of the outside air introduction passages 23 provided in the mist passage cover 3 are not particularly limited, but the outside air introduction passages 23 are provided so that the throttle portion 21 is located on the upstream side or when viewed from the discharge port 5 side. It is preferable to provide an arrangement so as to surround the aperture 21. The opening width of the outside air introduction path 23 is preferably 0.5 mm or more, and more preferably 2 mm or more.

なお、上記した各例のミスト吐出装置においては、高温のミストを発生させるミスト発生手段として沸騰室１を用い、高温のミストとしてスチームを発生させているが、他の構成によりミスト発生手段を形成してもよい。例えば、ミスト発生手段を、超音波で液体をミスト化した後に加熱する構成とすることや、ノズル噴射で液体をミスト化した後に加熱する構成とすることが考えられる。勿論、高温のミストを発生させることができる手段であれば、更に別の構成であっても構わない。   In the mist discharge device of each example described above, the boiling chamber 1 is used as the mist generating means for generating the high temperature mist and the steam is generated as the high temperature mist. However, the mist generating means is formed by other configurations. May be. For example, the mist generating means may be configured to be heated after the liquid is misted by ultrasonic waves, or to be heated after the liquid is misted by nozzle injection. Of course, another configuration may be used as long as it is a means capable of generating high temperature mist.
