Description

本発明は、浴室内をミストサウナ状態にすることができるミストサウナ装置に関する。   The present invention relates to a mist sauna device that can make a bathroom in a mist sauna state.

従来、この種のミストサウナ装置では、一般的に、浴室内に臨むミストノズルから水を噴霧するように構成されている。ところで、ミストノズルから噴霧されるミストの粒径は一定ではなく、粒径の大きな水滴状のミストもミストノズルから噴霧される。そして、上記従来例のものでは、ミストノズルから浴室内に水が直接噴霧されるため、粒径の大きな水滴状ミストが入浴者に当たって不快感を与えることがある。   Conventionally, this type of mist sauna apparatus is generally configured to spray water from a mist nozzle facing a bathroom. By the way, the particle size of the mist sprayed from the mist nozzle is not constant, and a water droplet mist having a large particle size is also sprayed from the mist nozzle. In the above conventional example, water is directly sprayed into the bathroom from the mist nozzle, so that the water droplet mist having a large particle size may hit the bather and give an uncomfortable feeling.

かかる不具合を解消するため、従来、ミスト用ダクトと、ミスト用ダクト内に水を噴霧するミストノズルとを備え、浴室の空気をミスト用ダクトを介して循環させることにより、ミストノズルから噴霧されたミストをミストノズル内の空気流に乗せて浴室に供給するようにしたミストサウナ装置も知られている(例えば、特許文献１参照)。これによれば、粒径の大きなミストはミスト用ダクト内の空気流に乗り切れず、ミスト用ダクトから浴室内に送風される空気中のミストはほぼ粒径の小さなものに限定され、水滴状のミストが入浴者に当たることを防止できる。   In order to eliminate such problems, conventionally, a mist duct and a mist nozzle that sprays water in the mist duct are provided, and the bathroom air is sprayed from the mist nozzle by circulating it through the mist duct. There is also known a mist sauna device in which mist is supplied to a bathroom on an air flow in a mist nozzle (see, for example, Patent Document 1). According to this, the mist having a large particle size cannot survive the air flow in the mist duct, and the mist in the air blown into the bathroom from the mist duct is limited to the one having a substantially small particle size. The mist can be prevented from hitting the bather.

更に、特許文献１に記載のものでは、ミスト用ダクト内にミストノズルより下流側に位置させて加熱器を設置し、ミストのみでは浴室内の温度上昇が不足する場合や浴室の乾燥を行う場合に、ミスト用ダクト内に流れる空気を加熱器で加熱するようにしている。   Furthermore, in the thing of patent document 1, it is located downstream from a mist nozzle in the duct for mist, a heater is installed, and when the temperature rise in a bathroom is insufficient only with mist, or when drying a bathroom In addition, the air flowing in the mist duct is heated by a heater.

ところで、ミスト用ダクト内にミストノズルから水を噴霧するものでは、ミスト用ダクトの壁面にミストが接触すると、ミストが冷却されて結露する。そして、結露するミストは粒径の大きいものに限らず、浴室に供給すべき粒径の小さなミストまでがダクト壁面に接触して結露する。そのため、ミストノズルから噴霧されたミストの利用効率が悪くなる。また、結露によるドレン量が増すため、ドレンがミスト用ダクトから溢れ出て浴室内に落下することを防止する上で、ドレン用の排水ポンプを頻繁に作動させなければならず、排水ポンプの消費電力が増大する。   By the way, in the case where water is sprayed from the mist nozzle into the mist duct, when the mist contacts the wall surface of the mist duct, the mist is cooled and condensed. The condensed mist is not limited to the one having a large particle size, and even a mist having a small particle size to be supplied to the bathroom contacts the duct wall surface to cause condensation. Therefore, the utilization efficiency of the mist sprayed from the mist nozzle is deteriorated. Also, since the amount of drainage due to condensation increases, the drainage drain pump must be operated frequently to prevent the drain from overflowing from the mist duct and falling into the bathroom. Power increases.

尚、ミスト用ダクト内にミストノズルより上流側に位置させて加熱器を設置し、加熱器で加熱された空気をミスト用ダクト内に流すことも考えられるが、ダクト壁面の温度は外方への放熱で左程上昇しないため、ドレン量の減少を図ることは困難である。
特開２０００−５５３９７号公報 It is also possible to install a heater in the mist duct upstream from the mist nozzle, and let the air heated by the heater flow into the mist duct. It is difficult to reduce the drain amount because the heat does not increase as much as left.
JP 2000-55397 A

本発明は、以上の点に鑑み、ダクト壁面での結露を抑制して、ミストノズルから噴霧されたミストの利用効率を向上できるようにしたミストサウナ装置を提供することをその課題としている。   This invention makes it the subject to provide the mist sauna apparatus which suppressed the dew condensation on a duct wall surface and can improve the utilization efficiency of the mist sprayed from the mist nozzle in view of the above point.

上記課題を解決するために、本発明は、ミスト用ダクトと、ミスト用ダクト内に水を噴霧するミストノズルとを備え、浴室の空気をミスト用ダクトを介して循環させることにより、ミストノズルから噴霧されたミストをミスト用ダクト内の空気流に乗せて浴室に供給するようにしたミストサウナ装置であって、浴室の空気をミスト用ダクトより上流側で加熱する加熱手段と、ミスト用ダクトを囲う外側ダクトとを備え、加熱手段で加熱された浴室の空気をミスト用ダクト内と外側ダクト内とに流し、ミスト用ダクト内を通過した空気だけでなく外側ダクト内を通過した空気も浴室内に吹出させることを特徴とする。 In order to solve the above problems, the present invention comprises a mist duct and a mist nozzle that sprays water in the mist duct, and circulates the air in the bathroom through the mist duct. A mist sauna device in which the sprayed mist is supplied to the bathroom by putting it on the air flow in the mist duct, and includes heating means for heating the bathroom air upstream from the mist duct, and a mist duct. and an outer duct surrounding, the air of the heated bath with heating means to flow into the inside and the outside duct mist duct, air also bathroom that has passed through the outer duct not only the air that has passed through the mist duct It is made to blow inside .

本発明によれば、ミスト用ダクトの壁面がミスト用ダクト内に流れる加熱空気と外側ダクト内に流れる加熱空気とで内外から加熱される。そのため、ミスト用ダクトの壁面での飽和水蒸気圧が高くなって、ダクト壁面での結露が抑制されると共に、ダクト壁面での気化が行われるようになり、ミストノズルから噴霧されるミストの利用効率が向上する。また、結露により発生するドレン（結露水）は排水ポンプで適宜排水する必要があるが、結露の抑制でドレン量が減少するため、排水ポンプの作動頻度が少なくなり、排水ポンプの消費電力を低減することができる。更に、ミスト用ダクトの下流端から吹出される水蒸気飽和した空気に外側ダクトからの乾燥空気が吹出し直後に混ざるため、吹出し後の結露が抑制され、ミストを効率良く浴室に供給できる。   According to the present invention, the wall surface of the mist duct is heated from inside and outside by the heated air flowing in the mist duct and the heated air flowing in the outer duct. Therefore, the saturated water vapor pressure on the wall surface of the mist duct is increased, condensation on the wall surface of the duct is suppressed, vaporization is performed on the wall surface of the duct, and the efficiency of using the mist sprayed from the mist nozzle is increased. Will improve. In addition, drain (condensation water) generated by condensation needs to be drained appropriately with a drain pump, but because the amount of drain decreases due to the suppression of condensation, the drain pump operation frequency is reduced and the power consumption of the drain pump is reduced. can do. Furthermore, since the dry air from the outer duct is mixed with the steam-saturated air blown from the downstream end of the mist duct immediately after blowing, dew condensation after blowing is suppressed, and mist can be efficiently supplied to the bathroom.

ところで、浴室の空気を加熱器で加熱しつつ循環させて浴室の暖房を行う浴室暖房機にミストサウナ装置を組み込むことがある。この場合、浴室の空気をミスト用ダクトより上流側で加熱する加熱手段を浴室暖房機の加熱器で構成すれば、別途加熱手段を設ける必要がなく、コストダウンを図る上で有利である。   By the way, a mist sauna apparatus may be incorporated in a bathroom heater that heats the bathroom by heating and circulating the bathroom air. In this case, if the heating means for heating the bathroom air upstream from the mist duct is configured by a heater of the bathroom heater, there is no need to provide a separate heating means, which is advantageous for cost reduction.

図１は本発明の実施形態のミストサウナ装置を組み込んだ浴室暖房機を示している。この浴室暖房機は、浴室の天井部に設置される箱形のハウジング１を備えている。ハウジング１の浴室に面する下面には、吸込み口２と、吸込み口２から離隔した暖房用吹出し口３１と、これに隣接するミスト用吹出し口３２（図２参照）とが開設されている。そして、ハウジング１内に吸込み口２と暖房用吹出し口３１とを結ぶ暖房用通風路４を画成している。 FIG. 1 shows a bathroom heater incorporating a mist sauna apparatus according to an embodiment of the present invention. This bathroom heater includes a box-shaped housing 1 installed on the ceiling of the bathroom. The lower surface facing the bathroom housing 1, and the suction port 2, inlet 2 was the air outlet 3 1 for heating apart from, mist blowing port 3 2 adjacent thereto (see FIG. 2) and is opened Yes. Then, defining the heating air passage 4 connecting the inlet 2 and the air outlet 3 1 for heating in the housing 1.

暖房用通風路４には、上流側の加熱器５と下流側の暖房用ファン６とが配置されている。図中６ａは暖房用ファン６の駆動モータである。加熱器５は、図外の熱源機で加熱された熱媒体（水、不凍液等）を熱媒循環路７を介して供給する気液熱交換器で構成されている。暖房用ファン６を駆動すれば、浴室の空気を加熱器５で加熱しつつ循環させて浴室の暖房を行うことができる。即ち、暖房用ファン６の回転で浴室の空気が吸込み口２から吸い込まれて加熱器５で加熱され、温風となって暖房用吹出し口３１から浴室に送風される。尚、加熱器５として電気ヒータを用いることも可能である。 An upstream heater 5 and a downstream heating fan 6 are arranged in the heating ventilation path 4. In the figure, reference numeral 6 a denotes a drive motor for the heating fan 6. The heater 5 is composed of a gas-liquid heat exchanger that supplies a heat medium (water, antifreeze liquid, etc.) heated by a heat source unit (not shown) through the heat medium circulation path 7. When the heating fan 6 is driven, the bathroom can be heated by circulating the air in the bathroom while being heated by the heater 5. That is, the air bath in rotation of the heating fan 6 is sucked from the suction port 2 is heated by the heater 5, is blown to the bath from the air outlet 3 1 for heating becomes warm air. An electric heater can also be used as the heater 5.

また、ハウジング１内には、ミスト用吹出し口３２に向けてのびるミスト用ダクト８と、浴室の空気をミスト用ダクト８を介して循環させるミスト用ファン９とが設置されている。図中９ａはミスト用ファン９の駆動モータである。ミスト用ダクト８には、図２に示す如く、水を噴霧するミストノズル１０が取付けられている。ミストノズル１０には、熱源機で加熱された熱媒体を供給する図外の液々熱交換器や熱源機の給湯部で加熱された水が給水路１１を介して供給される。 Further, in the housing 1, the mist duct 8 extending toward the mist blow-out port 3 2, and the mist fan 9 for circulating through the mist duct 8 is provided an air bath. In the figure, reference numeral 9a denotes a drive motor for the mist fan 9. A mist nozzle 10 for spraying water is attached to the mist duct 8 as shown in FIG. The mist nozzle 10 is supplied with water heated by a liquid heat exchanger (not shown) for supplying a heat medium heated by the heat source machine or a hot water supply unit of the heat source machine via a water supply path 11.

ミスト用ダクト８内にミストノズル１０から噴霧されたミストは、ミスト用ファン９の回転によりミスト用ダクト８に生ずる空気流に乗ってミスト用ダクト８の下流端に運ばれ、ミスト用吹出し口３２から浴室内に吹き出す。ここで、粒径の大きな水滴状のミストは空気流に乗り切らず、ミスト用吹出し口３２から吹き出すミストはほぼ粒径の小さなものに限定される。 The mist sprayed from the mist nozzle 10 into the mist duct 8 is carried to the downstream end of the mist duct 8 on the air flow generated in the mist duct 8 by the rotation of the mist fan 9, and the mist outlet 3 Blow out into the bathroom from 2 . Here, the large waterdrop-shaped mist of particle size not survive the airflow, mist blown from the blowing port 3 2 mist is limited to approximately the particle size of the small ones.

ここで、ミストノズル１０から噴霧されたミストの利用効率を向上するには、ミスト用ダクト８の壁面でのミストの結露を抑制する必要がある。そこで、本実施形態では、ミスト用ダクト８を囲う外側ダクト１２を設けている。そして、ミスト用ファン９を加熱器５の下流側の暖房用通風路４の部分に配置し、加熱器５で加熱された空気をミスト用ファン９によりミスト用ダクト８内と外側ダクト１２内とに流すようにしている。尚、外側ダクト１２の下流端は、ミスト用吹出し口３２に臨むミスト用ダクト８の下流端を囲うようにしてミスト用吹出し口３２に接続される。 Here, in order to improve the utilization efficiency of the mist sprayed from the mist nozzle 10, it is necessary to suppress dew condensation on the wall surface of the mist duct 8. Therefore, in the present embodiment, an outer duct 12 surrounding the mist duct 8 is provided. Then, the mist fan 9 is disposed in the portion of the heating ventilation path 4 on the downstream side of the heater 5, and the air heated by the heater 5 is moved into the mist duct 8 and the outer duct 12 by the mist fan 9. I am trying to make it flow. Incidentally, the downstream end of the outer duct 12 is connected so as to surround the downstream end of the mist duct 8 facing the air outlet 3 2 for mist blowing port 3 2 mist.

外側ダクト１２の下側には、ミスト用ダクト８の下壁に形成したドレン孔１３に連通するドレン受け１４が設けられている。そのため、ミスト用ダクト８内のドレンはドレン孔１３を介してドレン受け１４に流入する。ドレン受け１４には排水ポンプ１５を介設した排水路１６が接続されている。そして、ドレン受け１４内の水位が所定の高水位に上昇してこれを水位センサ（図示せず）が検出したとき、排水ポンプ１５を作動させて、ドレン受け１４内のドレンを排水するようにしている。   A drain receiver 14 that communicates with a drain hole 13 formed in the lower wall of the mist duct 8 is provided below the outer duct 12. Therefore, the drain in the mist duct 8 flows into the drain receiver 14 through the drain hole 13. A drain passage 16 having a drain pump 15 interposed is connected to the drain receiver 14. When the water level in the drain receiver 14 rises to a predetermined high water level and this is detected by a water level sensor (not shown), the drain pump 15 is activated to drain the drain in the drain receiver 14. ing.

ミストノズル１０から水を噴霧するミスト運転時には、加熱器５に熱媒体を供給すると共にミスト用ファン９を駆動する。これによれば、浴室の空気がミスト用ダクト８よりも上流側で加熱器５により加熱され、この加熱空気がミスト用ファン９を介してミスト用ダクト８と外側ダクト１２とに送られる。そして、ミスト用ダクト８の壁面がミスト用ダクト８内に流れる加熱空気と外側ダクト１２内に流れる加熱空気とで内外から加熱される。そのため、ミスト用ダクト８の壁面での飽和水蒸気圧が高くなって、ダクト壁面での結露が抑制されると共に、ダクト壁面での気化が行われるようになる。   During the mist operation in which water is sprayed from the mist nozzle 10, the heat medium is supplied to the heater 5 and the mist fan 9 is driven. According to this, the air in the bathroom is heated by the heater 5 on the upstream side of the mist duct 8, and this heated air is sent to the mist duct 8 and the outer duct 12 via the mist fan 9. The wall surface of the mist duct 8 is heated from inside and outside by the heated air flowing in the mist duct 8 and the heated air flowing in the outer duct 12. Therefore, the saturated water vapor pressure on the wall surface of the mist duct 8 is increased, and condensation on the duct wall surface is suppressed, and vaporization on the duct wall surface is performed.

更に、ミスト用ダクト８の下流端から吹出される水蒸気飽和した空気に外側ダクト１２からの乾燥空気が吹出し直後に混ざるため、吹出し後の結露も抑制され、ミストが効率良く浴室に供給される。その結果、ミスト用ダクト８の壁面での結露の抑制及び気化の促進と相俟って、ミストノズル１０から噴霧されたミストの利用効率が向上する。   Furthermore, since the dry air from the outer duct 12 is mixed with the steam-saturated air blown from the downstream end of the mist duct 8 immediately after the blowout, dew condensation after the blowout is suppressed, and the mist is efficiently supplied to the bathroom. As a result, combined with suppression of condensation on the wall surface of the mist duct 8 and promotion of vaporization, the utilization efficiency of the mist sprayed from the mist nozzle 10 is improved.

また、結露の抑制によりドレン受け１４に流入するドレンの量が減少する。そのため、排水ポンプ１５の作動頻度が少なくなり、排水ポンプ１５の電力消費量が減少する。これによりランニングコストの低減を図ることができる。   In addition, the amount of drain flowing into the drain receiver 14 is reduced by suppressing condensation. Therefore, the operation frequency of the drain pump 15 is reduced, and the power consumption of the drain pump 15 is reduced. As a result, the running cost can be reduced.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態では、浴室暖房機の加熱器５で加熱された空気をミスト用ファン９によりミスト用ダクト８及び外側ダクト１２に供給しているが、ミスト用ダクト８及び外側ダクト１２の上流端を暖房用ファン６の下流側の暖房用通風路４の部分に連通させ、暖房用ファン６から暖房用吹出し口３１に向けて送風される温風の一部をミスト用ダクト８及び外側ダクト１２に供給することも可能である。 As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above embodiment, the air heated by the heater 5 of the bathroom heater is supplied to the mist duct 8 and the outer duct 12 by the mist fan 9, but upstream of the mist duct 8 and the outer duct 12. end a is communicated with the downstream portion of the heating air passage 4 of the heating fan 6, the mist duct 8 and the outer part of the warm air blown toward the heating fan 6 to air outlet 3 1 for heating It is also possible to supply the duct 12.

また、上記実施形態では、ミスト用ダクト８及び外側ダクト１２に供給される空気をその上流側で加熱する加熱手段として浴室暖房機の暖房用の加熱器５を用いているが、ミスト用ダクト８及び外側ダクト１２に供給される空気を加熱するための専用の加熱手段を設けることも可能である。   Moreover, in the said embodiment, although the heater 5 for the heating of a bathroom heater is used as a heating means to heat the air supplied to the mist duct 8 and the outer duct 12 on the upstream side, the mist duct 8 is used. It is also possible to provide a dedicated heating means for heating the air supplied to the outer duct 12.

また、上記実施形態は浴室暖房機に組み込むミストサウナ装置に本発明を適用したものであるが、浴室暖房機から分離独立して設けられるミストサウナ装置にも同様に本発明を適用できる。   Moreover, although the said embodiment applies this invention to the mist sauna apparatus incorporated in a bathroom heater, this invention is applicable similarly to the mist sauna apparatus provided separately from a bathroom heater.
