【０００１】
【発明の属する技術分野】
本発明は、浴室内で加湿、昇温することで従来の浴室をサウナとして使用するための浴室サウナ装置に関する。
【０００２】
【従来の技術】
従来、この種の浴室サウナ装置は浴室側壁内部に設置され、ボイラーなどの熱源を利用して加湿、加熱を行うものが知られている（例えば、特許文献１参照）。
【０００３】
以下、その浴室サウナ装置について図を参照しながら説明する。
【０００４】
図６に示すように、図中１０１はスチームサウナ装置を構成するスチームサウナユニット本体で、このスチームサウナ本体１０１は浴室を形成するユニットバスルーム１０２のカウンタ部１０３内に設置されている。
【０００５】
前記スチームサウナユニット本体１０１は図７及び図８に示すように、外装体１０４を備え、この外装体１０４の前面中央部には、外部から空気Ａを吸入する空気吸入口１０５が、また、その下部にはスチーム吹出口１０６がそれぞれ開口されていると共に、このスチーム吹出口１０６には蒸気Ｓの噴出し方向を調整する風向調整板が設けられている。
【０００６】
さらに、前記外装体１０４の内部には噴出湯管１０７が上部位置に配置され、この噴出湯管１０７の下部には、熱交換促進部材１０８が配置されていると共に、この熱交換促進部材１０８の下部背面にはモータ駆動のファンユニット１０９が配置されている。
【０００７】
前記熱交換促進部材１０８は、上部１０８ａが前記外装体１０４の公報に位置するように傾斜し、かつ、その外装体１０４内の前方に位置する下部１０４ｂの背面側に前記ファンユニット１０９を配置している。
【０００８】
また、前記外装体１０４の下部で熱交換促進部材１０８の下方には排湯を受けるドレンパン１１０が設置され、ドレンパン１１０には内部にたまった排湯を排水するための排水口１１１が設けられている。
【０００９】
熱交換促進部材１０８はフィンチューブ式の熱交換器であり、配管内にボイラーなどの熱源から供給される高温の温水を流通させる事で外部を流通する流体と熱交換を行い加熱する。
【００１０】
噴出湯管１０７には複数の湯噴出口１１２が設けられており、給湯配管（図示せず）に接続される給湯口１１３から定流量弁１１４及び電磁弁１１５を介して噴出湯管１０７に温水を供給されることで湯噴出口１１２から熱交換促進部材１０８の上部に放散させ、熱交換促進部材１０８に流下した温水の一部が熱交換促進部材１０８内を流れる高温の温水と熱交換を行う事で蒸発し、この蒸発によって発生する蒸気Ｓをファンユニット１０９によってスチーム吹出口１０６から吹出す。

【００１４】
また、熱交換促進部材上を流下する温水が熱交換促進部材上を流下し終わるまでに完全には蒸発しきらないため、熱交換を行って温度が上昇した温水をドレンとして排水してしまうため、熱源の熱を廃棄する事になり効率が悪いと言う課題があり、熱源の熱を無駄に廃棄することなく効率の良い加湿を行う加湿部を搭載した浴室サウナ装置が要望されていた。

【００５８】
以下、本発明の実施例について図面を参照しながら説明する。
【００５９】
【実施例】
（実施例１）
図１に示すように、浴室１０２の天井裏部に設置するサウナ本体１０１は、図２に示すように、外装体１０４に浴室内の空気をサウナ本体に導入するための空気吸入口１０５及び、浴室１０２内の空気を吸入し加湿部へと送り、高温多湿になった空気を浴室内に送風するための送風機１０９、送風機１０９により浴室内から送られてきた空気を加湿するための加湿部１、加湿部により高温高湿になった空気を浴室１０２内に排出するための吹出し口１０６、加湿部に温水を循環させるための加湿水循環経路２、加湿水循環経路２内の温水を循環させるためのポンプ３、加湿水循環系路２上で加湿水を貯留するためのタンク４、熱源からの温水と加湿水循環経路２内を流れる加湿水を熱交換するための熱交換器５、タンク４に水を供給するための給水口６を備えている。
【００６０】
送風機１０９により浴室内から空気吸入口１０５を通ってサウナ本体に導入された空気は加湿部１に送られ、加湿部１内部で高温高湿の状態となった後、吹出し口１０６を通って浴室１０２に排出される。
【００６１】
加湿部１は図３に示すように、透湿性を有する多孔性材料を管状に形成した中空糸７を複数束ね、略円筒形状のケーシング８内に収納し、その両端部において、中空糸７の内側と外側が連通しないように複数の中空糸７の間をエポキシなどの樹脂９により封止してある。ケーシング８には中空糸７の内側の流路に空気を供給するための空気導入部１０、中空糸７内部の流路から空気を排出するための空気排出部１１、中空糸７の外側でケーシング８の内側に温水を供給するための温水導入部１２、中空糸７の外側でケーシング８の内側を流通してきた温水を加湿部１の外部へと排出するための温水排出部１３が設けられている。
【００６２】
加湿水循環経路２上のタンク４からポンプ３により送水された加湿用の水は加湿水循環経路２に接続された熱交換器５により熱源から送られてくる高温の温水と熱交換を行い、高温になった後、加湿部１の温水導入部１１より加湿部１内の中空糸７の外側、ケーシング８の内側の流路へと供給される。高温の加湿水は加湿部１内で透湿性をもつ中空糸７の内側の流路を通る空気と熱交換及び水蒸気の移行を行って低温となった後、温水排出部１３を経て温水排出部１３に接続された加湿水循環経路２へと排出される。加湿水循環経路２に排出された加湿後の温水は再びタンク４へと戻される。
【００６３】
タンク４内に貯留された加湿水は加湿部１で空気に供給され徐々に水量が減少する。このため、タンク４内には水位センサー１４を設け、タンク４内の加湿水の水量が一定以下の量となった場合に給水口６より市水を供給し、タンク４内の加湿水が無くならないようにしている。
【００６４】
上記のような構成を取る事により、熱源で高温にされた温水を熱交換器５に循環させる事により加湿水循環経路２内の加湿水を昇温し、高温となった加湿水を加湿部１に供給する事で加湿部１に供給される浴室１０２内の空気を加熱および加湿し、高温高湿となった空気を吹出し口１０６から浴室１０２内へと排出することで浴室１０２内の雰囲気を高温高湿なミストサウナ状態にすることが可能となる。
【００６５】
また、従来の方式のミストサウナ装置では、加湿に使用されなかった加湿水は加湿部１に設けられたドレンパンにより装置外部に排出されるため熱交換器５により昇温された温水が無駄に外部に廃棄されていたが、本発明における加湿部１では加湿に使用されなかった加湿水は再び加湿水循環経路２により熱交換器５へと送られ、再び高温となった状態で加湿部１に戻されるため、熱源から供給される熱を無駄に廃棄することが無く、従来の方式に比べ効率よく加湿を行う事が可能となる。
【００６６】
また、加湿部１に中空糸７を用いる事で比較的コンパクトなサイズの加湿部１でありながら、空気と温水の熱交換面積を大きく取る事が可能となり、比較的大容量な加熱及び加湿を行う事が可能となる。
【００６７】
さらに、本実施例のように、送風機の吹出し側に中空糸を用いた加湿部を設置する事で、送風機の吹出し側で生じる風切音などの騒音を中空糸部で吸収し、サウナ装置の吹出し部における騒音を低減する効果がある。
【００６８】
なお、本実施例において、中空糸とケーシングを封止するための樹脂としてエポキシ系材料を用いたが、中空糸の内側の流路と中空糸の外側の流路を連通しないように封止出来れば良く、ウレタンやシリコンなどの樹脂を用いてもその作用効果に差異を生じず、なお望ましくは高温の温水にさらされた雰囲気でも封止部が中空糸及びケーシングから脱落しないものが好ましい。
【００６９】
また、本実施例では透湿性を有する中空糸の材料を多孔性の透湿膜として特に指定しなかったが、高分子電解質膜のような非多孔性で空気を透過せずに、水蒸気のみを選択的に透過する性質を有する材料であれば良く、その作用効果に差異を生じず、なお好ましくは、液体の温水が透過しない材料である事が望ましい。
【００７０】
また、本実施例においては中空糸の内側の流路に空気を、中空糸の外側でケーシングの内側の流路に温水を流通させる構成としたが、逆に中空糸の内側の流路に温水を、中空糸の外側でケーシングの内側の流路に加湿用の温水を流通させる構成としても良く、その作用効果に差異を生じず、なお好ましくは、それぞれの流路を流通する空気及び加湿用の温水の加湿部における圧力損失が極力小さくなる事が望ましく、このために中空糸の内外径及びケーシング内に収納する本数、ケーシングの内径などを内部を流通する空気及び温水の流量に合わせて最適化する事が望ましい。
【００７１】
また、本実施例では送風機の吹出し側に中空糸を設ける構造としたが、送風機の吸込み側に中空糸を設置する構成としても良く、その作用効果に差異を生じない。ただし、送風機の吸込み側に中空糸を設置した場合、送風機を通過する空気が高温高湿な状態となるため、送風機は高温高湿な空気が流通しても結露や加熱などを起こさないものを選択する必要が生じる。さらに、送風機の吹出し側で生じる騒音を低減させるために送風機の吹出し部からサウナ装置の吹出し部までの区間に騒音を低減させるための騒音低減手段を設ける必要が生じる。
【００７２】
（実施例２）
以下、本発明の実施例２について図を参照しながら詳細に説明する。なお、本実施例において、実施例１と同等の作用をもつものについては同一の符号を付し、その詳細な説明を省略する。

【００７５】

図５に示すように、加湿水循環経路２中を流通する加湿水の循環流量を変化させた場合、熱交換器５出口部での加湿水の温度が変化するため、この影響を受けて、加湿部１における加湿量も変化する。加湿部１入口での加湿水の温度が一定の場合、加湿水の循環流量が多くなるのに伴って加湿部１での加湿量が増加する傾向となる。しかしながら、熱交換器５出口での加湿水の温度は加湿水の循環流量が増加することに伴って低くなる。加湿水の温度が低下した場合、加湿部における加湿量は加湿水の温度に伴って低下する傾向を示すため、加湿部１における加湿量はある循環流量を境に低下する傾向となる。このため、加湿部１における加湿量を最大とするためには加湿水の循環流量を最適な値とする必要が生じる。さらに上述した加湿量を最大にする為の最適加湿水循環量は、加湿部１に供給する空気の温度や湿度、風量や圧力、供給される温水の温度や外部の温度条件などによって変化する（図５中の条件▲１▼から条件▲２▼へ）。しかしながら、上述のような構成を取る事で、浴室内の雰囲気や熱源からの高温水の供給状態、浴室外の雰囲気の変動などが生じた場合でもホームサウナ装置から浴室内に供給される空気の状態を常に高温高湿な状態に保つ事が可能となり、より効率良く、多くの加湿量を供給する事が可能なホームサウナ装置が得られる。
【００７７】
なお、本実施例においては、循環流量制御部で加湿水循環系路内を循環する加湿水の循環量を決定する際にあらかじめ用意された算出式を用いて加湿水の循環量を決定する方式を取ったが、あらかじめ用意されたデータテーブルをもとに最適な循環流量を決定する方式を取っても良く、その作用効果に差異を生じない。
【００７８】
また、本実施例においては加湿水循環系路内を循環する加湿水流量を変化させるために循環水量制御装置を用いて加湿水流量を変化させる構成としたが、加湿水を循環させるためのポンプの駆動量を変化させる事によって加湿水の循環量を変化させる方式を取っても良く、その作用効果に差異を生じない。
【００７９】
【発明の効果】
以上の実施例から明らかなように、本発明によれば、比較的コンパクトで設置可能な浴室を限定せず、多くの加湿量を得ることができ、また、熱源からの熱を無駄に捨てる事が無く、効率の良い加熱加湿を行う事ができる浴室サウナ装置を提供できる。
【００８０】
また、本発明によれば、加湿部における加湿を効率よく行う事が可能となり、浴室に供給する加湿量を多くする事が可能となる。

[0058]
Embodiments of the present invention will be described below with reference to the drawings.
[0059]
【Example】
(Example 1)
As shown in FIG. 1, the sauna body 101 installed in the ceiling back part of the bathroom 102 is, as shown in FIG. 2, an air inlet 105 for introducing the air in the bathroom to the exterior body 104 into the sauna body, and The air in the bathroom 102 is inhaled and sent to the humidifying unit, and the humidifier 1 for humidifying the air sent from the inside of the bathroom by the blower 109 to blow the hot and humid air into the bathroom. The air outlet 106 for exhausting the air that has become hot and humid by the humidifying part into the bathroom 102, the humidifying water circulation path 2 for circulating hot water in the humidifying part, and the hot water in the humidifying water circulating path 2 for circulating Pump 3, tank 4 for storing the humidified water on the humidified water circulation path 2, heat exchanger 5 for exchanging heat between the hot water from the heat source and the humidified water flowing in the humidified water circulating path 2, and water in the tank 4 To supply It is equipped with a water supply port 6.
[0060]
The air introduced into the sauna body from the bathroom through the air suction port 105 by the blower 109 is sent to the humidifying unit 1, becomes hot and humid inside the humidifying unit 1, and then passes through the outlet 106 to the bathroom. 102 is discharged.
[0061]
As shown in FIG. 3, the humidifying unit 1 bundles a plurality of hollow fibers 7 in which a porous material having moisture permeability is formed into a tubular shape, and accommodates the hollow fibers 7 in a substantially cylindrical casing 8. A plurality of hollow fibers 7 are sealed with a resin 9 such as epoxy so that the inner side and the outer side do not communicate with each other. The casing 8 includes an air introduction part 10 for supplying air to the flow path inside the hollow fiber 7, an air discharge part 11 for discharging air from the flow path inside the hollow fiber 7, and a casing outside the hollow fiber 7. A hot water introduction part 12 for supplying warm water to the inside of the hot water 8 and a warm water discharge part 13 for discharging the warm water flowing through the inside of the casing 8 outside the hollow fiber 7 to the outside of the humidifying part 1 are provided. Yes.
[0062]
The water for humidification sent from the tank 4 on the humidification water circulation path 2 by the pump 3 exchanges heat with the high-temperature hot water sent from the heat source by the heat exchanger 5 connected to the humidification water circulation path 2 to increase the temperature. After that, the hot water introduction part 11 of the humidification part 1 is supplied to the flow path inside the hollow fiber 7 inside the humidification part 1 and inside the casing 8. The high-temperature humidified water is subjected to heat exchange and steam transfer with air passing through the flow path inside the hollow fiber 7 having moisture permeability in the humidifying section 1 and then becomes a low temperature, and then passes through the warm water discharging section 13 to the warm water discharging section. 13 is discharged to the humidified water circulation path 2 connected to 13. The humidified hot water discharged to the humidified water circulation path 2 is returned to the tank 4 again.
[0063]
The humidified water stored in the tank 4 is supplied to the air in the humidifying unit 1 and the amount of water gradually decreases. For this reason, a water level sensor 14 is provided in the tank 4, and when the amount of humidified water in the tank 4 falls below a certain level, city water is supplied from the water supply port 6, and there is no humidified water in the tank 4. I try not to be.
[0064]
By taking the configuration as described above, the temperature of the humidified water in the humidified water circulation path 2 is increased by circulating hot water heated to a high temperature by the heat source 5 to the humidified portion 1. The air in the bathroom 102 supplied to the humidifying unit 1 is heated and humidified, and the atmosphere in the bathroom 102 is exhausted from the outlet 106 into the bathroom 102 by heating and humidifying the air. A high temperature and high humidity mist sauna can be achieved.
[0065]
Further, in the conventional type mist sauna apparatus, the humidified water that has not been used for humidification is discharged outside the apparatus by the drain pan provided in the humidifying section 1, so that the warm water heated by the heat exchanger 5 is wasted. However, the humidified water that has not been used for humidification in the humidifying unit 1 of the present invention is sent again to the heat exchanger 5 through the humidifying water circulation path 2 and returned to the humidifying unit 1 in a state where the temperature becomes high again. Therefore, heat supplied from the heat source is not wasted, and humidification can be performed more efficiently than in the conventional method.
[0066]
In addition, by using the hollow fiber 7 for the humidifying unit 1, it is possible to increase the heat exchange area of air and hot water while the humidifying unit 1 has a relatively compact size, and relatively large capacity heating and humidification can be achieved. Can be done.
[0067]
Furthermore, as in this embodiment, by installing a humidifying unit using hollow fibers on the blowout side of the blower, noise such as wind noise generated on the blowout side of the blower is absorbed by the hollow fiber portion, and the sauna device There is an effect of reducing noise in the blowout part.
[0068]
In this example, an epoxy-based material was used as the resin for sealing the hollow fiber and the casing, but the resin can be sealed so that the flow path inside the hollow fiber and the flow path outside the hollow fiber do not communicate with each other. Even if a resin such as urethane or silicone is used, it is preferable that the effect does not differ even when the resin is used, and that the sealing portion is preferably not dropped from the hollow fiber and the casing even in an atmosphere exposed to high-temperature hot water.
[0069]
Further, in this example, the hollow fiber material having moisture permeability was not specified as a porous moisture permeable membrane, but only water vapor was used without being permeated through air such as a polymer electrolyte membrane. Any material may be used as long as it has a property of selectively permeating, and it is desirable that the material does not cause a difference in operation and effect and does not allow liquid warm water to permeate.
[0070]
In this embodiment, air is flown through the flow path inside the hollow fiber, and hot water is circulated through the flow path inside the casing outside the hollow fiber. The warm water for humidification may be circulated in the flow path inside the casing outside the hollow fiber, and there is no difference in the function and effect. Preferably, the air circulates in each flow path and for humidification. It is desirable that the pressure loss in the humidifying part of the hot water is as small as possible. For this reason, the inner and outer diameters of the hollow fibers, the number of the hollow fibers stored in the casing, the inner diameter of the casing, etc. It is desirable to make it.
[0071]
In the present embodiment, the hollow fiber is provided on the blower side of the blower. However, the hollow fiber may be provided on the suction side of the blower, and there is no difference in the operational effect. However, when a hollow fiber is installed on the suction side of the blower, the air that passes through the blower is in a high-temperature and high-humidity state, so the blower does not cause condensation or heating even when high-temperature and high-humidity air flows. There is a need to choose. Furthermore, in order to reduce the noise generated on the blower side of the blower, it is necessary to provide noise reduction means for reducing noise in the section from the blower part of the blower to the blower part of the sauna device.

Hereinafter, Example 2 of the present invention will be described in detail with reference to the drawings. In the present embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
[0073]
FIG. 4 is a schematic view of the sauna apparatus main body 101 in the present embodiment. The suction temperature measuring device 15 that measures the temperature of the suction air is sucked into the suction port 105 that sucks the air in the bathroom 102 into the sauna apparatus main body 101, and is blown out to the blowout port 106 that blows out the air that has become hot and humid by the humidifying unit 1 The temperature measurement device 16 and the blowout humidity measurement device 17 that measures the humidity of the blown air are measured. The blowing pressure measuring device 19 is connected to a humidifying water inlet temperature measuring device 20 at the inlet of the humidifying portion 1 on the humidifying water circulation path 2, a humidifying water outlet temperature measuring device 21 at the outlet of the humidifying portion 1 on the humidifying water circulation path 2, and the sauna. An external temperature measuring device 22 that measures the ambient temperature outside the bathroom 102 outside the apparatus main body 101 is connected to the heat exchanger 5 inlet in the high-temperature water supply path from the heat source. Providing a degree measuring device 23, respectively.
[0074]
Further, a circulating water amount control unit 24 for calculating the circulation amount of the humidifying water circulating in the humidifying water circulation system 2 based on the temperature, pressure, and air flow detected by each of the measuring devices described above is provided, and the humidifying water circulation system 2 A circulation amount control device 25 that circulates inside is provided on the humidified water circulation path 2.
[0075]
When the sauna apparatus main body 101 is operated, the suction temperature measuring device 15, the blowing temperature measuring device 16, the blowing humidity measuring device 17, the air flow measuring device 18, the blowing pressure measuring prime 19, the humidifying water inlet temperature measuring device 20, and the humidifying water outlet temperature. The temperature, pressure, and air flow data measured by the measuring device 21, the external temperature measuring device 22, and the heat exchanger inlet temperature measuring device 23 are sent to the circulating water amount control unit 24. A humidification water circulation amount that maximizes the humidification amount in the humidification unit 1 is calculated according to the temperature condition, the pressure condition, and the air flow rate. For calculation, a calculation formula stored in advance in the circulation amount control unit 24 is used. The circulation amount control unit 24 operates the circulation flow rate control device 25 based on the calculated humidification water circulation amount, and the circulation amount control unit 24 calculates the circulation amount of the humidification water flowing in the humidification water circulation system path 2. To change.
[0076]
As shown in FIG. 5, when the circulation flow rate of the humidified water flowing through the humidified water circulation path 2 is changed, the temperature of the humidified water at the outlet of the heat exchanger 5 changes. The amount of humidification in part 1 also changes. When the temperature of the humidified water at the inlet of the humidifying unit 1 is constant, the humidification amount in the humidifying unit 1 tends to increase as the circulation flow rate of the humidified water increases. However, the temperature of the humidified water at the outlet of the heat exchanger 5 decreases as the circulating flow rate of the humidified water increases. When the temperature of the humidified water decreases, the humidification amount in the humidification part tends to decrease with the temperature of the humidification water, so the humidification amount in the humidification part 1 tends to decrease at a certain circulation flow rate. For this reason, in order to make the humidification amount in the humidification part 1 the maximum, it becomes necessary to make the circulation flow rate of humidification water into an optimal value. Further, the optimum humidified water circulation amount for maximizing the humidification amount described above varies depending on the temperature and humidity of the air supplied to the humidifying unit 1, the air flow and pressure, the temperature of the supplied hot water, external temperature conditions, and the like (FIG. 5) from condition (1) to condition (2). However, by adopting the configuration as described above, even when the atmosphere in the bathroom, the supply state of high-temperature water from the heat source, or the fluctuation of the atmosphere outside the bathroom occur, the air supplied from the home sauna device to the bathroom It becomes possible to keep the state constantly in a high temperature and high humidity state, and a home sauna apparatus capable of supplying a large amount of humidification more efficiently can be obtained.
[0077]
In this embodiment, when the circulation flow rate control unit determines the circulation amount of the humidification water circulating in the humidification water circulation system, a method for determining the circulation amount of the humidification water using a calculation formula prepared in advance is used. However, a method of determining an optimum circulation flow rate based on a data table prepared in advance may be adopted, and there is no difference in the operation effect.
[0078]
In the present embodiment, the flow rate of the humidified water is changed using the circulating water amount control device in order to change the flow rate of the humidified water circulating in the humidified water circulation system, but the pump for circulating the humidified water is used. A method of changing the circulation amount of the humidified water by changing the driving amount may be adopted, and there is no difference in the operation effect.
