Description

本発明は、蒸気圧を利用して液体を吸い上げ噴霧する蒸気式吸入器に関する。   The present invention relates to a vapor inhaler that sucks up and sprays liquid using vapor pressure.

この種の蒸気式吸入器として、例えば図１３に示すように、給水タンク７０と、この給水タンク７０の側方に配置されたヒータ７１と、給水タンク７０とヒータ７１との間に設けられ、下部が給水タンク７０の底部に給水路７２で連通し、上部が給水タンク７０の上部に蒸気連通路７３で連通する加熱室７４と、この加熱室７４で発生した蒸気を外部に噴出するノズル７５とを備える蒸気発生装置を配備してなり、この蒸気発生装置のノズル７５から噴出される蒸気により吸入液を吸い上げて噴霧するものが知られている（例えば、特許文献１参照）。   As this type of steam inhaler, for example, as shown in FIG. 13, a water supply tank 70, a heater 71 disposed on the side of the water supply tank 70, and between the water supply tank 70 and the heater 71, A heating chamber 74 whose lower portion communicates with the bottom of the water supply tank 70 through a water supply passage 72 and whose upper portion communicates with the upper portion of the water supply tank 70 via a steam communication passage 73, and a nozzle 75 that ejects steam generated in the heating chamber 74 to the outside. There is known a system in which a steam generating device is provided, and the suction liquid is sucked up and sprayed by steam ejected from a nozzle 75 of the steam generating device (see, for example, Patent Document 1).

このような蒸気式吸入器では、電源投入後から噴霧が開始されるまでの時間を短くするために、給水タンク７０をタンク室７６と加熱室７４に距離を置いて分離した構造になっている。即ち、タンク室７６内の水をヒータにより加熱するのではなく、タンク室７６内の水を加熱室７４に導入し、加熱室７４でヒータにより加熱するようになっている。
特開平７−３９５８５号公報 Such a vapor inhaler has a structure in which the water supply tank 70 is separated from the tank chamber 76 and the heating chamber 74 at a distance in order to shorten the time from when the power is turned on until the spraying is started. . That is, the water in the tank chamber 76 is not heated by the heater, but the water in the tank chamber 76 is introduced into the heating chamber 74 and heated by the heater in the heating chamber 74.
Japanese Unexamined Patent Publication No. 7-39585

上記のような蒸気式吸入器では、特に鼻吸入の場合、吸入時間は長時間（１０分以上）が望まれており、噴霧量は喉吸入の場合に比べて少ない方が良い。喉及び鼻の吸入を一台の吸入器で行い、且つコンパクトで上記要望を達成するために、一台の吸入器でヒータへの通電パワーを切り替えて吸入時間と噴霧量を喉及び鼻吸入に応じて調節することも試みられている。   In the vapor inhaler as described above, in particular, in the case of nasal inhalation, it is desired that the inhalation time is long (10 minutes or more), and the amount of spray is preferably smaller than that in the case of throat inhalation. To achieve throat and nasal inhalation with a single inhaler and to achieve the above requirements with a compact inhaler, the inhalation time and spray amount can be changed to throat and nasal inhalation by switching the energizing power to the heater with a single inhaler. Attempts have also been made to adjust accordingly.

しかしながら、上記のような蒸気式吸入器で通電パワーを切り替えて使用すると、次の問題点が生じる。   However, the following problems arise when the energized power is switched in the steam inhaler as described above.

すなわち、噴霧の効率を良くするためには加熱室７４の容量を多くして沸騰量を増やす必要があるが、この場合は噴霧開始までの時間が長くなるという問題点に関連し、加熱室７４の容量を多くした場合、加熱室７４で沸騰させる水量が多くなるため、例えば途中で通電パワーを半減すると水が沸き難くなり、息づきを起こし易くなる。   That is, in order to improve the efficiency of spraying, it is necessary to increase the volume of the heating chamber 74 and increase the amount of boiling. In this case, the heating chamber 74 is related to the problem that the time until spraying starts becomes long. When the capacity is increased, the amount of water to be boiled in the heating chamber 74 increases. For example, if the energizing power is reduced by half during the process, it becomes difficult to boil water, and breathing is likely to occur.

従って、本発明は、そのような問題点に着目してなされたもので、
（ａ）途中でヒータへの通電パワーを切り替えた際、息づきや噴霧の停止がなく、スムーズに噴霧の勢いを落とす。
（ｂ）電源投入後から噴霧開始までの時間を短くすると共に、最後まで安定した噴霧状態を確保する。
を実現する蒸気式吸入器を提供することを目的とする。 Therefore, the present invention has been made paying attention to such problems,
(A) When the energization power to the heater is switched in the middle, there is no breathing or stop of spraying and the spraying force is smoothly dropped.
(B) The time from power-on to the start of spraying is shortened, and a stable spray state is ensured until the end.
It aims at providing the vapor type inhaler which realizes.

前記目的を達成するために、本発明の請求項１記載の蒸気式吸入器は、タンク室を備える給水タンクと、この給水タンクの側方に配置されたヒータと、給水タンクとヒータとの間に設けられ、下部が給水タンクの底部に連通し、上部が給水タンクの上部に連通する加熱室と、この加熱室で発生した蒸気を外部に噴出するノズルとを備える蒸気発生装置を配備してなるものにおいて、タンク室と加熱室が給水タンクの１枚の側壁により仕切られるとともに、この給水タンクの１枚の側壁を通じて連通し、前記１枚の側壁は加熱室の奥行きが下部よりも上部が狭くなるように形成され、ヒータが給水タンクの前記１枚の側壁に沿って上下に配置された２枚の発熱素子からなることを特徴とする。 In order to achieve the above object, a steam inhaler according to claim 1 of the present invention includes a water supply tank having a tank chamber, a heater disposed on the side of the water supply tank, and between the water supply tank and the heater. Provided with a heating chamber having a lower portion communicating with the bottom of the water supply tank and an upper portion communicating with the upper portion of the water supply tank, and a nozzle for ejecting the steam generated in the heating chamber to the outside. In this case, the tank chamber and the heating chamber are separated by one side wall of the water supply tank, and communicated through one side wall of the water supply tank. The one side wall has a heating chamber whose depth is higher than the lower portion. The heater is composed of two heating elements that are formed so as to be narrow and are arranged vertically along the one side wall of the water supply tank.

この蒸気式吸入器において、２枚の発熱素子は、電源投入初期に２枚とも通電され、霧化開始後の任意の時点でいずれか１枚がＯＦＦされるように設定されるのが好ましい。   In this vapor inhaler, it is preferable that the two heating elements are set so that both are energized at the beginning of power-on, and one of them is turned off at an arbitrary time after the start of atomization.

また、ＯＦＦされる発熱素子は、上側に位置する発熱素子であるのが好ましい。   Moreover, it is preferable that the heating element to be turned off is a heating element located on the upper side.

更に、２枚の発熱素子に対する通電切替は、ヒータに直接又は伝熱板を介して取付けたサーモスタットを利用して行われるのが好適である。   Furthermore, it is preferable that the energization switching of the two heating elements is performed using a thermostat attached to the heater directly or via a heat transfer plate.

本発明（請求項１の構成）によれば、ヒータが給水タンクの１枚の側壁に沿って上下に配置された２枚の発熱素子からなるため、喉吸入時には、噴霧量の多い勢いのよい霧で短時間の吸入が可能であり、鼻吸入時には、噴霧量の少ない柔らかい霧で長時間の吸入が可能となる。
また、タンク室と加熱室が給水タンクの１枚の側壁により仕切られるとともに、この給水タンクの１枚の側壁を通じて連通するので、水が最後まで効率良く蒸発する。しかも、噴霧後にタンク室（給水タンク）と加熱室との底部連通路に水は残り難く、当該底部連通路が水垢等で詰まることもない。更に、タンク室（給水タンク）と加熱室との上部連通路での熱的損失も少なく、熱効率が良い。
更に、１枚の側壁は加熱室の奥行きが下部よりも上部が狭くなるように形成されているので、加熱室下部で沸き始めた水を上部で加速的に再加熱することができ、熱効率が大変良い。しかも、加熱室下部が上部より広くなるため、水位が減っても息づき等の霧化不安定な状態にはならない程度の水量を最後まで確保できる。 According to the present invention (structure of claim 1), the heater is composed of two heating elements arranged vertically along one side wall of the water supply tank. Inhalation with a mist for a short time is possible, and during nasal inhalation, a long time inhalation is possible with a soft mist with a small spray amount.
Further, since the tank chamber and the heating chamber are partitioned by one side wall of the water supply tank and communicate with each other through the one side wall of the water supply tank, water is efficiently evaporated to the end. Moreover, it is difficult for water to remain in the bottom communication passage between the tank chamber (water supply tank) and the heating chamber after spraying, and the bottom communication passage is not clogged with scale. Furthermore, there is little thermal loss in the upper communication path between the tank chamber (water tank) and the heating chamber, and the thermal efficiency is good.
Furthermore, since one side wall is formed so that the depth of the heating chamber is narrower at the top than at the bottom, water that has started to boil at the bottom of the heating chamber can be accelerated and reheated at the top. Very good. In addition, since the lower part of the heating chamber is wider than the upper part, it is possible to secure a sufficient amount of water to the end without causing an unstable atomization state such as breathing even if the water level decreases.

請求項２の構成によれば、電源投入後から噴霧開始までの時間を短くすることができるとともに、最後まで安定した噴霧状態を確保することができる。また、噴霧が途切れることなくヒータへの通電パワーを半減することができる。   According to the configuration of the second aspect, it is possible to shorten the time from the power-on to the start of spraying, and to ensure a stable spray state until the end. Moreover, the energization power to the heater can be halved without spraying being interrupted.

請求項３の構成によれば、よりスムーズに噴霧の勢いを落とすことができる。   According to the structure of Claim 3, the force of spray can be dropped more smoothly.

以下、本発明の蒸気式吸入器を実施例に基づいて説明する。但し、本発明は蒸気式吸入器に配備される蒸気発生装置に特徴があるため、蒸気発生装置を中心に説明する。   Hereinafter, the vapor inhaler of the present invention will be described based on examples. However, since the present invention is characterized by the steam generator provided in the steam inhaler, the description will focus on the steam generator.

まず、蒸気発生装置の要部断面図を図１に示す。この蒸気発生装置は、給水タンク１０と、この給水タンク１０の側部１０ａに配置されたヒータ１１と、給水タンク１０とヒータ１１との間に設けられ、下部が給水タンク１０の底部に連通し、上部が給水タンク１０の上部に連通する加熱室１２と、この加熱室１２で発生した蒸気を外部に噴出するノズル（図１では図示せず）とを備える。   First, a cross-sectional view of the main part of the steam generator is shown in FIG. The steam generator is provided between a water supply tank 10, a heater 11 disposed on a side portion 10 a of the water supply tank 10, and between the water supply tank 10 and the heater 11, and a lower portion communicates with a bottom portion of the water supply tank 10. The heating chamber 12 has an upper portion communicating with the upper portion of the water supply tank 10 and a nozzle (not shown in FIG. 1) for ejecting steam generated in the heating chamber 12 to the outside.

特徴的な構成は、給水タンク１０の側部１０ａに上下方向に延びる凹部１３を形成し、この凹部１３にヒータ１１を上下方向に配置し、側部１０ａとヒータ１１との間に形成される空間を加熱室１２としたことである。即ち、加熱室１２は側部１０ａとヒータ１１で包囲された空間であり、この加熱室１２が側部１０ａによりタンク室１４と仕切られ、ヒータ１１が側部１０ａに沿って付設された様態である。給水タンク１０のタンク室１４と加熱室１２とは、側部１０ａの底部に形成された給水口１５で連通すると共に、側部１０ａの上部に形成された蒸気連通口１６で連通する。   A characteristic configuration is that a concave portion 13 extending in the vertical direction is formed in the side portion 10 a of the water supply tank 10, and the heater 11 is disposed in the concave portion 13 in the vertical direction, and is formed between the side portion 10 a and the heater 11. The space is the heating chamber 12. That is, the heating chamber 12 is a space surrounded by the side portion 10a and the heater 11, and the heating chamber 12 is partitioned from the tank chamber 14 by the side portion 10a, and the heater 11 is attached along the side portion 10a. is there. The tank chamber 14 and the heating chamber 12 of the water supply tank 10 communicate with each other through a water supply port 15 formed at the bottom of the side portion 10a and also through a steam communication port 16 formed at the top of the side portion 10a.

このような蒸気発生装置では、タンク室１４内の水Ｗは、給水口１５を通じて加熱室１２に流入し、ヒータ１１で加熱・沸騰され、発生した蒸気は、蒸気連通口１６を通じてタンク室１４に入り、更に給水タンク１０の上部適所に設けられたノズル（図３の符号１７参照）から装置外部に噴出される。   In such a steam generator, the water W in the tank chamber 14 flows into the heating chamber 12 through the water supply port 15, is heated and boiled by the heater 11, and the generated steam enters the tank chamber 14 through the steam communication port 16. Furthermore, it is ejected to the outside of the apparatus from a nozzle (see reference numeral 17 in FIG. 3) provided at an appropriate position above the water supply tank 10.

このような蒸気発生装置は、加熱室１２とヒータ１１が省スペース的に設けられた構造であるため、図２の（ａ）に示すように小型化することができる。これに対し、図１３に示すような従来の装置は、図２の（ｂ）の如く加熱室とヒータ１１が給水タンク１０から離れて配置されているため、小型化の点で不利である。なお、図２中の符号１７はノズルである。   Since such a steam generator has a structure in which the heating chamber 12 and the heater 11 are provided in a space-saving manner, it can be miniaturized as shown in FIG. On the other hand, the conventional apparatus as shown in FIG. 13 is disadvantageous in terms of miniaturization because the heating chamber and the heater 11 are arranged away from the water supply tank 10 as shown in FIG. In addition, the code | symbol 17 in FIG. 2 is a nozzle.

又、給水口１５と蒸気連通口１６は、共に側部１０ａ（即ち給水タンク１０の側壁）に孔を開けただけのものであるため、図１３に示す従来の装置における給水路７２や蒸気連通路７３に比べて、それぞれ距離ａ，ｂが相当短い。従って、水が最後まで効率良く蒸発する。しかも、噴霧後に給水口１５に水は残り難く、給水口１５が水垢等で詰まることもない。又、蒸気連通口１６での熱的損失も少なく、熱効率が良い。更に、この実施例では、加熱室１２の奥行き（ヒータ１１と給水タンク１０の側部１０ａとの間隔）は、上下方向に変化しており、下部から中央部付近までの間隔Ｃ１が中央部付近から上部までの間隔Ｃ２より大きく設定されているが、この点については次に説明する。   Further, since both the water supply port 15 and the steam communication port 16 are merely provided with holes in the side portion 10a (that is, the side wall of the water supply tank 10), the water supply path 72 and the steam communication port in the conventional apparatus shown in FIG. Compared to the passage 73, the distances a and b are considerably shorter. Therefore, water evaporates efficiently to the end. Moreover, it is difficult for water to remain in the water supply port 15 after spraying, and the water supply port 15 is not clogged with scales. Further, there is little thermal loss at the steam communication port 16, and the thermal efficiency is good. Further, in this embodiment, the depth of the heating chamber 12 (the distance between the heater 11 and the side portion 10a of the water supply tank 10) changes in the vertical direction, and the interval C1 from the lower part to the vicinity of the central part is near the central part. Is set to be larger than the interval C2 from the top to the top. This point will be described next.

加熱室１２の奥行きを上下方向に変化させる種々の具体例を図３〜図７に示す。まず、図３の（ａ）はヒータ付きの蒸気発生装置の要部断面図を示し、図３の（ｂ）はヒータを外した状態の蒸気発生装置をヒータ側から見た側面図を示す。図３の例は、加熱室１２の奥行きを階段状に変化させたものであり、図１と同様に、給水口１５から中央部付近までの奥行きより中央部付近から蒸気連通口１６までの奥行きが狭く、加熱室１２の断面形状は２段構造になっている。ここでは、給水口１５は側部１０ａの底部のほぼ中央に形成され、蒸気連通口１６は側部１０ａの上部の両側に２つ形成されている。又、給水タンク１０のタンク室１４の底部は、加熱室１２（即ち給水口１５）に向かって下方に緩やかに傾斜している。図４の例では、加熱室１２の奥行きが３段階に変化しており、蒸気連通口１６が側部１０ａの上部にわたって設けられている。   Various specific examples of changing the depth of the heating chamber 12 in the vertical direction are shown in FIGS. First, FIG. 3A shows a cross-sectional view of the main part of a steam generator with a heater, and FIG. 3B shows a side view of the steam generator with the heater removed as seen from the heater side. In the example of FIG. 3, the depth of the heating chamber 12 is changed stepwise. Similar to FIG. 1, the depth from the water supply port 15 to the vicinity of the central portion to the depth from the central portion to the steam communication port 16. The cross-sectional shape of the heating chamber 12 has a two-stage structure. Here, the water supply port 15 is formed substantially at the center of the bottom of the side portion 10a, and two steam communication ports 16 are formed on both sides of the upper portion of the side portion 10a. The bottom of the tank chamber 14 of the water supply tank 10 is gently inclined downward toward the heating chamber 12 (that is, the water supply port 15). In the example of FIG. 4, the depth of the heating chamber 12 is changed in three stages, and the steam communication port 16 is provided over the upper portion of the side portion 10a.

図５に示す例は、加熱室１２の奥行きをテーパ状に変化させたものである。即ち、加熱室１２は底部から上部に向かって連続的に狭くなっている。図６に示す例では、加熱室１２の断面形状は２段構造になっているが、中央部付近から蒸気連通口１６より内側部分１０ａ-1のみがその他の部分１０ａ-2より狭くなっている。更に、図７に示す例では、加熱室１２の断面形状は３段構造になっているが、真中に最も奥行きの狭い部分が設けられている。 In the example shown in FIG. 5, the depth of the heating chamber 12 is changed to a taper shape. That is, the heating chamber 12 is continuously narrowed from the bottom to the top. In the example shown in FIG. 6, the cross-sectional shape of the heating chamber 12 has a two-stage structure, but only the inner portion 10 a −1 from the steam communication port 16 is narrower than the other portion 10 a -2 from near the center. . Furthermore, in the example shown in FIG. 7, the cross-sectional shape of the heating chamber 12 has a three-stage structure, but the portion with the narrowest depth is provided in the middle.

上記図３〜図７の例は、いずれも加熱室１２の少なくとも給水口１５付近の奥行きより、それよりも上方の部分の奥行きが狭くなっていると共に、タンク室１４の底部が加熱室１２に向かって下方に傾斜している。加熱室１２の上部より下部が広くなっているため、加熱室１２の下部で沸き始めた水は上部で加速的に再加熱されて蒸気が発生し、効率が良い。又、タンク室１４内の水位が低下しても、息づき等の霧化不安定な状態にならない程度の水量を最後まで確保できる。   In the examples of FIGS. 3 to 7 described above, the depth of the portion above the water supply port 15 in the heating chamber 12 is narrower than that of the heating chamber 12, and the bottom of the tank chamber 14 becomes the heating chamber 12. It is inclined downward. Since the lower part is wider than the upper part of the heating chamber 12, the water that starts to boil in the lower part of the heating chamber 12 is accelerated and reheated in the upper part to generate steam, which is efficient. Moreover, even if the water level in the tank chamber 14 is lowered, it is possible to secure a sufficient amount of water to the end so as not to cause an unstable atomization such as breathing.

ヒータ１１は、図８に示すように、給水タンク１０の側部１０ａに沿って上下に配置された２枚の発熱素子２１，２２を有し、発熱素子２１が加熱室１２の上部に、発熱素子２２が加熱室１２の下部に対応する。このヒータ１１は、その周囲に形成された８つの取付孔２３ａ，２４ａに例えばネジを通し、給水タンク１０に形成された対応孔２３ｂ，２４ｂに螺合することで、側部１０ａに固定される。図９において、ヒータ１１に対する通電切替に利用されるサーモスタット３０は、断熱シート３１を介してヒータ１１にネジ３２で固定された伝熱板３３上に取付けてもよいし、或いはヒータ１１上に直接取付けても構わない。なお、断熱シート３１としては、熱を少し伝え難くしてサーモスタット３０への熱供給を調整するものであればよく、準断熱シート、軽断熱シート、少断熱シート等を含む。   As shown in FIG. 8, the heater 11 includes two heating elements 21 and 22 arranged vertically along the side portion 10 a of the water supply tank 10, and the heating element 21 generates heat in the upper part of the heating chamber 12. The element 22 corresponds to the lower part of the heating chamber 12. The heater 11 is fixed to the side portion 10a by passing, for example, screws through the eight mounting holes 23a and 24a formed around the heater 11 and screwing into the corresponding holes 23b and 24b formed in the water supply tank 10. . In FIG. 9, the thermostat 30 used for energization switching to the heater 11 may be mounted on a heat transfer plate 33 fixed to the heater 11 with screws 32 via a heat insulating sheet 31, or directly on the heater 11. You may attach. In addition, as the heat insulation sheet 31, what is necessary is just to make it difficult to convey heat a little and to adjust the heat supply to the thermostat 30, and a semi heat insulation sheet, a light heat insulation sheet, a small heat insulation sheet, etc. are included.

ヒータ１１、サーモスタット３０等からなる回路構成例を図１０に示す。この回路では、ＡＣ１００Ｖ３５の一方側において、ヒータ１１の下部の発熱素子２２が直接接続され、上部の発熱素子２１がサーモスタット３０を介して接続され、他方側において、ヒューズ３６を介して２回路・３接点の通電切替スイッチ３７が接続されている。通電切替スイッチ３７の接点Ｐ１は喉吸入時用であり、接点Ｐ２は鼻吸入時用である。この回路によると、スイッチ３７を喉吸入時用の接点Ｐ１にしておき、電源を投入すると、サーモスタット３０のＯＮ／ＯＦＦにかかわらず、発熱素子２１，２２が通電される。一方、スイッチ３７を鼻吸入時用の接点Ｐ２にしておき、電源を投入すると、最初はサーモスタット３０のＯＮ状態で発熱素子２１，２２に通電されるが、ヒータ１１の温度が上昇してサーモスタット３０がＯＦＦ状態になると、上部の発熱素子２１がＯＦＦになり、ヒータ１１への通電パワーが半減する。   FIG. 10 shows a circuit configuration example including the heater 11, the thermostat 30, and the like. In this circuit, the lower heating element 22 of the heater 11 is directly connected to one side of the AC 100 V 35, the upper heating element 21 is connected via the thermostat 30, and the other circuit is connected to the two circuits 3 through the fuse 36. A contact energization switch 37 is connected. The contact P1 of the energization switch 37 is for throat inhalation, and the contact P2 is for nasal inhalation. According to this circuit, when the switch 37 is set to the contact point P1 for throat inhalation and the power is turned on, the heating elements 21 and 22 are energized regardless of whether the thermostat 30 is on or off. On the other hand, when the switch 37 is set to the contact point P2 for inhaling the nose and the power is turned on, the heating elements 21 and 22 are initially energized while the thermostat 30 is on, but the temperature of the heater 11 rises and the thermostat 30 is turned on. Is turned off, the upper heating element 21 is turned off, and the energization power to the heater 11 is halved.

この図１０のような回路でヒータ１１に通電した場合のヒータ表面温度と通電時間との関係を図１１に示す。喉吸入時には、噴霧量の多い勢いのよい霧で短時間の吸入が可能であり、鼻吸入時には、噴霧量の少ない柔らかい霧で長時間の吸入が可能となる。   FIG. 11 shows the relationship between the heater surface temperature and the energization time when the heater 11 is energized by the circuit as shown in FIG. When inhaling the throat, it is possible to inhale for a short time with a strong mist with a large amount of spray, and when inhaling the nose, it is possible to inhale for a long time with a soft mist with a small amount of spray.

次に、上記の如き蒸気発生装置を組み込んだ蒸気式吸入器全体の構造を図１２（要部断面図）に示す。ここでは、吸入器の本体ケース４０の所定箇所に、蒸気発生装置１が固定され、給水タンク１０には、タンク室１４の蒸気圧が異常に高くなった場合に蒸気圧を逃すためのコイルバネ４６と安全弁４７を有するキャップ４１が嵌着されている。蒸気発生装置１（即ち給水タンク１０）から突出するノズル（蒸気ノズル）１７は、本体ケース４０に着脱可能に配置された吸入液カップ４２内に延びるチューブ４３の端部に取付けられた吸入ノズル４４と隣接対向しており、吸入液カップ４２内には吸入液が収容される。両ノズル１７，４４は、噴霧ガイド４５内に位置決めされている。   Next, the structure of the whole vapor | steam type inhaler incorporating the above steam generators is shown in FIG. 12 (main part sectional drawing). Here, the steam generator 1 is fixed at a predetermined position of the main body case 40 of the inhaler, and the coil spring 46 for releasing the steam pressure when the steam pressure in the tank chamber 14 becomes abnormally high in the water supply tank 10. And a cap 41 having a safety valve 47 is fitted. A nozzle (steam nozzle) 17 protruding from the steam generator 1 (that is, the water supply tank 10) is a suction nozzle 44 attached to an end of a tube 43 extending into a suction liquid cup 42 detachably disposed in the main body case 40. And inhalation liquid is accommodated in the inhalation liquid cup 42. Both nozzles 17 and 44 are positioned in the spray guide 45.

蒸気発生装置１で発生した蒸気は、その蒸気圧により蒸気ノズル１７から噴出する。この時、吸入ノズル４４の先端は負圧になるため、吸入液カップ４２内の吸入液は、チューブ４３を通じて吸い上げられ、蒸気ノズル１７からの蒸気圧により霧状になり、噴霧ガイド４５から噴霧される。   The steam generated in the steam generator 1 is ejected from the steam nozzle 17 by the steam pressure. At this time, since the tip of the suction nozzle 44 becomes a negative pressure, the suction liquid in the suction liquid cup 42 is sucked up through the tube 43, becomes a mist by the steam pressure from the steam nozzle 17, and is sprayed from the spray guide 45.
