【０００６】
（ニ）シャワールームに一般的な換気扇や気流吹き出し装置を設置しても、気流の強さや方向が一定でなく、このため、換気効率が十分でなかったり、或いは、突発的に強い気流が発生して、使用者の体温が低下したり、騒音が発生する虞があった。
（ホ）シャワールームの内部から塩素ガスを排出するだけでは、塩素ガス自体を除去することにはならないので、外部環境を汚染する心配がある。
この発明は、以上のような問題点を解決し、高齢者や病人でも不快感を感ずることなく、全身を効果的に洗浄・殺菌できる酸性水シャワー装置を設置したシャワールームを提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明のシャワールームは、水を電気分解して強酸性水を生成する強酸性水生成装置を加温装置の入口側に接続し、加温装置の出口側を洗浄空間に設置されたシャワーヘッドの入口側に接続して成る酸性水シャワー装置を備え、前記洗浄空間の上部に、一定方向で、最大風速と最小風速とが平均風速に対して±２０％以内の空気を下方に向けて流す一様空気流吹き出し装置を、下部に排気口をそれぞれ設けて、前記洗浄空間内の塩素ガスを排出する。
加温した強酸性水をシャワー吐水する構成により、全身を洗浄しても不快感を感ずることがなく、ホースやコックを介して散水するものに比べて、広い範囲を洗浄しやすく、使用水量が節約される。
狭いシャワールームで、加温した強酸性水をシャワー吐水しても、発生した塩素ガスを一定方向及び一定風速の空気で下方に押し流すと共に、排気口から排出することによって、使用者が吸引するのを防ぎ、シャワールーム内の塩素ガス濃度を安全レベルに抑える。
【０００８】
強酸性水生成装置の強酸性水排出部及び強酸性水の生成と同時に生成されたアルカリ水の排出部並びに原水の供給管を切換装置の入口部に接続し、切換装置は用途に応じて強酸性水、アルカリ水及び原水のいずれかをシャワーヘッドに供給することができる。
加温装置によって強酸性水、アルカリ水及び原水を、２５℃から５０℃の範囲内で加温しても良い。
【０００９】
前記シャワーヘッドは孔径０．６５ mm 〜１ mm の吐水口を有するのが望ましい。このような吐水口からシャワー吐水することにより、適度な太さの水流となり空気との接触が抑えられるので、シャワー吐水後に吐水口から少なくとも２ｍ以内の距離において、ｐＨ２．１〜２．７、酸化還元電位１１００〜１２００ｍＶ、残留塩素濃度２０〜６０ｐｐｍ程度の性能を維持する。この結果、吐水口から人の身長よりもやや高い２ｍ以内の範囲では、殺菌効果が低下することがない。
また、排気口に塩素ガス用の吸収缶又は活性炭繊維を取り付け、排気中の塩素ガスを除去して、シャワールーム外の環境汚染を防止することができる。
【００１０】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳細に説明する。
図１及び図２に示すように、本発明のシャワールーム１は、洗浄空間２の側方に機器収納部３を設けて成る。
機器収納部３には、酸性水シャワー装置４の構成部品である強酸性水生成装置６及び加温装置５が収納され、酸性水シャワー装置４を操作する操作盤１２及びシャワーヘッド７が洗浄空間２に露出されている。
【００１１】
図３に示すように、酸性水シャワー装置４の強酸性水生成装置６は、従来公知のものであって、隔膜で区画された陽極室と陰極室とを有し、これら陽極室及び陰極室にそれぞれ水道水より成る原水が導入されるようになってる。そして、陽極室に設けた陽極板及び陰極室に設けた陰極板に所定の電圧を印加することによって、供給された原水が電気分解され、陽極室には強酸性水が、陰極室にはアルカリ水がそれぞれ分離される。
なお、一般的な水道水等をそのまま電気分解して、十分な殺菌力のある強酸性水を得るには、大量のエネルギーを必要とするので、陽極板及び陰極室に導入する前段階において、原水に食塩等の電離性有機質を添加し、これを電気分解すると、ｐＨ値がやや高くても十分な殺菌力のある強酸性水が得られる。
【００１２】
加温装置５は、入口側が水位センサを介して強酸性水生成装置６の強酸性水排出部及びアルカリ水排出部に、それぞれ酸性水一次タンク１３ａ、アルカリ水一次タンク１３ｂを介して接続された酸性水加温タンク５ａ、アルカリ水加温タンク５ｂと、強酸性水生成装置６を通過せずに原水の供給管に接続される水加温タンク５ｃとから成る。
そして、強酸性水生成装置６で生成された強酸性水及びアルカリ水が、それぞれ陽極室及び陰極室から導出されて酸性水一次タンク１３ａ及びアルカリ水一次タンク１３ｂに注入され、さらに第１のポンプ１４及び第２のポンプ１５によって、酸性水加温タンク５ａ及びアルカリ水加温タンク５ｂに送られるようになっている。
【００１３】
酸性水加温タンク５ａ、アルカリ水加温タンク５ｂ及び水加温タンク５ｃには、それぞれサーモスタット１６を有するヒータ１７が設けられ、これらのヒータ１７は操作盤１２に接続されている。そして、酸性水加温タンク５ａ、アルカリ水加温タンク５ｂ及び水加温タンク５ｃは、洗浄空間２から操作盤１２を操作することによって、強酸性水、アルカリ水及び原水を２５℃〜５０℃の範囲で適宜温度に加温できるようになっている。
また、酸性水加温タンク５ａ及びアルカリ水加温タンク５ｂには、それぞれ第１のポンプ１４及び第２のポンプ１５に接続された水位センサ１８が設けられると共に、水加温タンク５ｃにはボールタップ１９が設置され、内部の水位が一定に保たれるようになっている。
【００１４】
シャワーヘッド７への供給部には切換装置８が設置され、この切換装置８が操作盤１２に接続されている。また、強酸性水生成装置６の強酸性水排出部は酸性水加温タンク５ａ及び第３のポンプ２０を介して、アルカリ水排出部はアルカリ水加温タンク５ｂ及び第４のポンプ２１を介して、原水の供給管は水加温タンク５ｃ及び第５のポンプ２２を介して、それぞれ切り換え装置８の入口側に接続される。
そして、洗浄空間２から操作盤１２を介して切換装置８を切換操作することにより、強酸性水、アルカリ水及び原水のいずれか、又は原水でアルカリ水を希釈したものがシャワーヘッド７の吐水口からシャワー吐水されるようになっている。
【００１５】
シャワーヘッド７の吐水口は、吐水される強酸性水の水流が適度な太さとなって、空気と触れにくくなるよう、０．６５mm〜１mmの孔径としてある。
なお、酸性水シャワー装置４の強酸性水と接触する可能性がある部品は、できる限り金属以外の素材によって形成することが望ましいが、やむを得ず金属製部品とする場合には、その表面に保護コーティングを施して強酸性水で侵され難くする。
【００１６】
洗浄空間２は、合成樹脂、タイル等の耐水材料によって内装を施されており、その床部には排水口が形成されている。そして、この排水口と強酸性水生成装置６から延びるパイプとは、同じ排水系統１１に接続される（図１，図３）。
また、図２に示すように、洗浄空間２の上部に一様空気流吹き出し装置９が設置されると共に、四周壁の下端部に排気口１０が設けられる。
一様空気流吹き出し装置９は、風量切換可能であって、一定方向及び一定風速の空気を下方に向けて連続的に流し続けるようになっている。
排気口１０には、塩素ガス用の吸収缶或いは活性炭繊維が流路を遮るように配設され、排気中の塩素ガスを除去して、外部環境が汚染されるのを防止する。
【００１７】
洗浄空間２の内部に設置されてシャワー吐水される強酸性水と接触する可能性のある金属製部品、例えば、ネジ等の固定具、操作盤やシャワーヘッドの表面部品等には、保護コーティングを施してある。
なお、強酸性水生成装置６に食塩水を供給して、食塩水を電気分解することにより強酸性水と強アルカリ水とを生成することもできる。この場合は、強酸性水生成装置６の直前或いは装置内に、電気分解前の原水へ食塩を添加する装置を設ける。
また、洗浄空間２の内壁面に、シャワーヘッド７と取水切換可能なコックを設けても良い。このようにすると、強酸性水を容器に貯めて、器具等を殺菌するのに便利である。
【００１８】
【実施例】
４０℃に加温した強酸性水を、孔径１mmの吐水口及び孔径０．６５mmと孔径０．３５mmとを混在させた吐水口からそれぞれシャワー吐水させ、吐水口からの距離が０mmのａ地点、５００mm離れたｂ地点、１０００mm離れたｃ地点及び２０００mm離れたｄ地点において、有効塩素濃度、ｐＨ値及び酸化還元電位（ＯＲＰ値）を計測し、この結果を表２に示す。
【００１９】
【表２】

【００２０】
表２に示す試験結果から、加温した強酸性水をシャワー吐水させた時、吐水口の孔径が変化しても、ｐＨ値及びＯＲＰ値はそれほど変化しない。そこで、様々な塩素濃度の強酸性水を、孔径０．６５mmと孔径０．３５mmとを混在させた吐水口、孔径１mmの吐水口及び孔径０．６５mmの吐水口からシャワー吐水し、各吐水口についてａ，ｂ，ｃ，ｄの各地点における有効塩素濃度をさらに精度を上げて測定し、その結果をそれぞれ表３、表４及び表５に示す。
【００２１】
【表３】

【００２２】
【表４】

【００２３】
【表５】

【００２４】
これらの試験結果から、吐水口の孔径を１mmとすれば、吐水口から２ｍ以内の距離においても、ｐＨ値２．１〜２．７、酸化還元電位１１００〜１２００ｍＶ、有効塩素濃度２０〜６０ｐｐｍの性能を維持し、使用者の全身に達する前に、殺菌効果が低下することはなく、また、試験結果のばらつきを考慮すると、吐水口の孔径が０．６５mm以上であれば、ほぼ必要な性能を満たすことができると考えられる。
【００２５】
次に、一様空気流吹き出し装置９を稼働したときの、洗浄空間２における塩素ガス濃度と排気口１０のサイズとの関係を調べた。
洗浄空間２の床面から１９００mmの高さにシャワーヘッド７を設置し、このシャワーヘッド７の吐水口から温度４２℃、ｐＨ２．４、有効塩素濃度６０ｐｐｍの強酸性水を吐水し、一様空気流吹き出し装置９を風速０．４ｍ／ｓで稼働した。
そして、洗浄空間２の四周壁に、排気口１０を床面から４００mmまでの高さまで設けた場合、及び床面から１００mmの高さまで設けた場合について、シャワーヘッド７の高さｈ１、シャワーヘッド７よりも９５０mm下方の高さｈ２及び排気口１０の上端の高さｈ３（図１）の各高さにおける塩素ガス濃度を計測した結果は表６に示す通りであり、すべての計測結果が安全基準である１ｐｐｍを下回っていることがわかる。
【００２６】
【表６】

【００２７】
使用者にとって快適な一様空気流吹き出し装置９の風速を知るために、洗浄空間２の床から１８００mmの高さにおける平均風速を０．６ｍ／ｓ，０．８ｍ／ｓ，１．０ｍ／ｓ，１．２ｍ／ｓ，１．４ｍ／ｓ，２．０ｍ／ｓに変化させて、図４（洗浄空間２を下から見た図）に示すように、洗浄空間２の中央Ａと、洗浄空間２を縦横に４等分した各空間Ｂ，Ｃ，Ｄ，Ｅの中央においてシャワーを使用した時、各風速によって感じた皮膚感覚をアンケート調査した。
この結果、風速が１．２ｍ／ｓ及び１．４ｍ／ｓではやや寒く、２．０ｍ／ｓではかなり寒さを感ずるが、１．０ｍ／ｓ以下では寒さを感じず快適であることがわかった。
【００２８】
塩素除去効果の点から望ましい一様空気流吹き出し装置９の風速を次のようにして調べた。洗浄空間２の四周壁に設けた排気口１０の高さを１００mmとし、床から５００mmの高さにおける平均風速を０．２ｍ／ｓ，０．４ｍ／ｓ，０．６ｍ／ｓに変化させた時の空気の流れを、発煙管を使用して目視により確認し、表７に示す。
この結果、十分な換気を行うためには、床から５００mmの高さにおいて、少なくとも０．２ｍ／ｓの風速が必要であると考えられる。
【００２９】
【表７】

【００３０】
また、洗浄空間２の様々な地点において、風速のばらつきが大きすぎると、塩素ガスの滞留等が生じやすいので、各高さごとに、最大風速と最小風速とが平均風速に対して±２０％以内でなければならない。
洗浄空間２の床から１８００mmの高さ丸数字１、１５００mmの高さ丸数字２、１０００mmの高さ丸数字３、５００mmの高さ丸数字４において、上記各地点Ａ，Ｂ，Ｃ，Ｄ，Ｅの風速を計測すると共に、計測平均に対する最大風速及び最小風速のばらつき（乱れ率）を求めた。丸数字１での設定風速を０．６ｍ／ｓとした時の結果を表８に示し、丸数字１での設定風速を０．８ｍ／ｓとした時の結果を表９に示した。
さらに、比較例として、一様空気流吹き出し装置９に代えて、旋回流を生ずる一般的な換気扇を用い、丸数字１での設定風速を０．６ｍ／ｓとした時の結果を表１０に、丸数字４での設定風速を０．４ｍ／ｓとした時の結果を表１１に、丸数字４での設定風速を０．３ｍ／ｓとした時の結果を表１２にそれぞれ示した。
なお、表８乃至表１２において、各地点での設定風速と、実験時に計測したその地点での平均風速とをぴったり一致させることは難しく、若干のずれがあるので、表中には計測値をそのまま記載した。
【００３１】
【表８】

【００３２】
【表９】

【００３３】
【表１０】

【００３４】
【表１１】

【００３５】
【表１２】

【００３６】
これらの試験結果から、一般的な換気扇では、乱れ率が±２０％を越えており、風が充分届かない場所が生じたり、強い風が発生して寒さを感じさせることがあるのに対し、一様空気流吹き出し装置９では風速が平均化され、換気効率がよいことが確認された。
また、一様空気流吹き出し装置９を用いても、平均風速が０．６ｍ／ｓでは弱すぎて乱れ率が±２０％を越えてしまい、皮膚感覚に関するアンケート調査の結果と合わせて、一様空気流吹き出し装置９を用い、しかも、丸数字１での平均風速を０．８ｍ／ｓ〜１．０ｍ／ｓにすると、換気効率が良く、使用者に寒さを感じさせることもないことがわかった。
なお、洗浄空間２は閉塞空間であるため、一様空気流吹き出し装置９を設置するだけでも十分な換気効果が得られるが、排気口１０に排気装置を設けると、いっそう換気効率が高まる。
【００３７】
【発明の効果】
請求項１に係る発明によれば、加温した強酸性水をシャワー吐水するので、気温が低くても不快感を感ずることなく全身を洗浄・殺菌することができ、ホースやコックを介して散水するものに比べて、広い範囲を洗浄しやすく、使用水量も少なくて済む。
また、全身を洗浄している間に、吐水口から離れた位置に飛散した強酸性水の殺菌効果が低下することがない。

BACKGROUND OF THE INVENTION
The present invention relates to a shower room that was installed acidic water shower equipment for the whole body can be washed.
[0002]
[Prior art]
Strong acid water has strong bactericidal activity and is highly safe and has little persistence. Therefore, it is friendly to the health and environment of the user. For this reason, povidone iodine and alcoholic substances that have been used for hand sanitization, etc. It is being replaced by disinfectants.
Currently, strong acid water generators are provided by many manufacturers, and only a few of them are approved by the Ministry of Health and Welfare as medical devices for hand sanitization.
[0003]
[Problems to be solved by the invention]
When trying to sterilize and clean the whole body with strongly acidic water, there were the following problems.
(B) When washing with strong acid water, strong acid water at room temperature is used, but this is cold and unsuitable for whole body washing, especially for sick people and elderly people.
(B) Since the conventional strong acid water generator is a flowing water type or a batch type, the generated strong acid water is collected from a hose or a cock and used for washing. Accordingly, the water pressure is small and the diffusion is difficult, so that it is not suitable for a wide range of cleaning.
[0004]
(C) When strongly acidic water is heated and discharged from the shower, chlorine gas contained in the strongly acidic water is likely to diffuse. In particular, when a shower is used in a narrow enclosed space such as a shower room, the filled chlorine gas is sucked, which may cause not only a strong odor but also a life threatening.
A shower room with a cross section of 1000 mm x 1000 mm and a height of 2100 mm is sealed, and strongly acidic water heated to 40 ° C is discharged for 1 minute, and the point x is 1000 mm away from the spout at a distance of 1000 mm. The results of measuring the chlorine gas concentration at a certain y point and a z point at a distance of 2000 mm are as shown in Table 1, and these concentrations far exceed the 1 ppm which is the allowable concentration determined by the Japan Society for Occupational Health. Over.
[0005]
[Table 1]

[0006]
(D) Even if a general ventilation fan or air blowout device is installed in the shower room, the strength and direction of the airflow are not constant, and therefore the ventilation efficiency is not sufficient or suddenly strong airflow is generated. As a result, the user's body temperature may decrease or noise may occur.
(E) Simply exhausting chlorine gas from the inside of the shower room does not remove the chlorine gas itself, so there is a concern of contaminating the external environment.
This invention is to solve the above problems, without having to feel discomfort in the elderly and the sick, to provide a shower room that was installed acidic water shower equipment that systemic can be effectively cleaned and sterilized Let it be an issue.
[0007]
[Means for Solving the Problems]
The shower room of the present invention is a shower head in which a strongly acidic water generator for electrolyzing water to generate strongly acidic water is connected to the inlet side of the heating device, and the outlet side of the heating device is installed in the cleaning space An acidic water shower device connected to the inlet side of the water is provided, and air with a maximum wind speed and a minimum wind speed within ± 20% of the average wind speed is directed downward in a fixed direction above the cleaning space. The uniform air flow blowing device is provided with an exhaust port at the lower part to discharge chlorine gas in the cleaning space .
The structure that discharges warm strongly acidic water does not cause discomfort even if the whole body is washed, and it is easier to wash a wider area than watering through a hose or cock, and the amount of water used is Saved.
Even when showering with warm acidic water that has been heated in a narrow shower room, the generated chlorine gas is swept downward by air at a constant direction and at a constant wind speed, and the user sucks it by discharging it from the exhaust port. And keep the chlorine gas concentration in the shower room to a safe level.
[0008]
The strong acid water discharge unit of the strong acid water generator, the discharge unit of alkaline water generated simultaneously with the generation of strong acid water, and the supply pipe of the raw water are connected to the inlet of the switching device. Any of basic water, alkaline water and raw water can be supplied to the shower head.
You may heat strongly acidic water, alkaline water, and raw | natural water within the range of 25 to 50 degreeC with a heating apparatus.
[0009]
The shower head preferably has a water outlet having a hole diameter of 0.65 mm to 1 mm . By performing shower water discharge from such a water outlet, the water flow has an appropriate thickness and contact with air is suppressed. Therefore, at a distance of at least 2 m from the water outlet after shower water discharge, pH 2.1 to 2.7, oxidation The performance of a reduction potential of 1100 to 1200 mV and a residual chlorine concentration of about 20 to 60 ppm is maintained. As a result, the sterilizing effect does not decrease within a range of 2 m, which is slightly higher than the height of the person from the spout.
Moreover, an absorption can or an activated carbon fiber for chlorine gas can be attached to the exhaust port, and chlorine gas in the exhaust can be removed to prevent environmental pollution outside the shower room.
[0010]

The raw water supply pipe is connected to the inlet side of the switching device 8 via the water heating tank 5c and the fifth pump 22, respectively.
Then, by switching the switching device 8 from the cleaning space 2 via the operation panel 12, the strongly acidic water, the alkaline water and the raw water, or the alkaline water diluted with the raw water is the water outlet of the shower head 7. From the shower water is discharged.
[0015]
The water outlet of the shower head 7 has a hole diameter of 0.65 mm to 1 mm so that the flow of strongly acidic water to be discharged has an appropriate thickness and is difficult to come into contact with air.
In addition, it is desirable that the parts that may come into contact with the strong acid water of the acidic water shower device 4 should be made of a material other than metal as much as possible. To make it hard to be attacked by strong acid water.
[0016]
The cleaning space 2 is decorated with a water-resistant material such as synthetic resin or tile, and a drain outlet is formed on the floor portion.

[0018]
【Example】
Strong acidic water heated to 40 ° C. was discharged from a water outlet with a hole diameter of 1 mm and a water outlet with a mixture of a hole diameter of 0.65 mm and a hole diameter of 0.35 mm. The effective chlorine concentration, pH value, and oxidation-reduction potential (ORP value) were measured at a point b 500 mm away, a point c 1000 mm away, and a point d 2000 mm away, and the results are shown in Table 2.
[0019]
[Table 2]

[0020]
From the test results shown in Table 2, the pH value and the ORP value do not change so much even when the pore size of the spout changes when the heated strongly acidic water is discharged from the shower. Therefore, showering of strongly acidic water with various chlorine concentrations from a water outlet with a pore diameter of 0.65 mm and a hole diameter of 0.35 mm, a water outlet with a hole diameter of 1 mm, and a water outlet with a hole diameter of 0.65 mm. The effective chlorine concentration at each point of a, b, c and d was measured with higher accuracy, and the results are shown in Table 3, Table 4 and Table 5, respectively.
[0021]
[Table 3]

[0022]
[Table 4]

[0023]
[Table 5]

[0024]
From these test results, if the diameter of the water outlet is 1 mm, the pH value is 2.1 to 2.7, the oxidation-reduction potential is 1100 to 1200 mV, and the effective chlorine concentration is 20 to 60 ppm even at a distance within 2 m from the water outlet. The performance is maintained and the bactericidal effect does not decrease before reaching the whole body of the user. Considering the variation in the test results, if the hole diameter of the water outlet is 0.65 mm or more, it is almost necessary performance. It is thought that it can satisfy.
[0025]
Next, the relationship between the chlorine gas concentration in the cleaning space 2 and the size of the exhaust port 10 when the uniform air flow blowing device 9 was operated was examined.
A shower head 7 is installed at a height of 1900 mm from the floor of the cleaning space 2, and strongly acidic water having a temperature of 42 ° C., a pH of 2.4, and an effective chlorine concentration of 60 ppm is discharged from the water outlet of the shower head 7, and uniform air The blowout device 9 was operated at a wind speed of 0.4 m / s.
The height h1 of the shower head 7 and the height of the shower head 7 when the exhaust port 10 is provided up to 400 mm from the floor surface and at a height of 100 mm from the floor surface are provided on the four circumferential walls of the cleaning space 2. Table 6 shows the results of measurement of the chlorine gas concentration at each height of 950 mm below the height h2 and the height h3 of the upper end of the exhaust port 10 (FIG. 1), and all the measurement results are safety standards. It can be seen that it is below 1 ppm.
[0026]
[Table 6]

[0027]
In order to know the wind speed of the uniform air flow blowing device 9 comfortable for the user, the average wind speed at a height of 1800 mm from the floor of the cleaning space 2 is 0.6 m / s, 0.8 m / s, 1.0 m / s. , 1.2 m / s, 1.4 m / s, and 2.0 m / s, as shown in FIG. 4 (view of the cleaning space 2 from below), the center A of the cleaning space 2 and the cleaning When a shower was used at the center of each of the spaces B, C, D, and E obtained by dividing the space 2 into four equal parts, the skin sensation felt by each wind speed was surveyed.
As a result, it was found that when the wind speed was 1.2 m / s and 1.4 m / s, it was slightly cold, and when it was 2.0 m / s, it felt quite cold, but at 1.0 m / s or less, it was comfortable without feeling cold. .
[0028]
The wind speed of the uniform air flow blowing device 9 desirable from the point of chlorine removal effect was examined as follows. The height of the exhaust port 10 provided on the four circumferential walls of the cleaning space 2 is 100 mm, and the average wind speed at a height of 500 mm from the floor is changed to 0.2 m / s, 0.4 m / s, and 0.6 m / s. The air flow at the time was visually confirmed using a smoke tube and is shown in Table 7.
As a result, it is considered that a wind speed of at least 0.2 m / s is required at a height of 500 mm from the floor in order to perform sufficient ventilation.
[0029]
[Table 7]

[0030]
In addition, if the variation in the wind speed is too large at various points in the cleaning space 2, stagnation of chlorine gas or the like is likely to occur. Therefore, the maximum wind speed and the minimum wind speed are ± 20% with respect to the average wind speed at each height. Must be within.
From the floor of the cleaning space 2, 1800 mm height circle number 1, 1500 mm height circle number 2, 1000 mm height circle number 3, 500 mm height circle number 4, the above points A, B, C, D, While measuring the wind speed of E, the dispersion | variation (turbulence rate) of the maximum wind speed and the minimum wind speed with respect to the measurement average was calculated | required. Table 8 shows the results when the set wind speed at the circled numeral 1 is 0.6 m / s, and Table 9 shows the results when the set wind speed at the circled numeral 1 is 0.8 m / s.
Further, as a comparative example, instead of the uniform air flow blowing device 9, a general ventilation fan that generates a swirl flow is used, and the results when the set wind speed in the circled numeral 1 is 0.6 m / s are shown in Table 10. Table 11 shows the results when the set wind speed at the round numeral 4 is 0.4 m / s, and Table 12 shows the results when the set wind speed at the round numeral 4 is 0.3 m / s.
In Tables 8 to 12, it is difficult to exactly match the set wind speed at each point and the average wind speed at that point measured during the experiment, and there is a slight deviation. It is described as it is.

From these test results, in a general ventilation fan, the turbulence rate exceeds ± 20%, there are places where the wind does not reach enough, or strong winds may be generated, making it feel cold. In the uniform air flow blowing device 9, the wind speed was averaged, and it was confirmed that the ventilation efficiency was good.
Further, even when the uniform airflow blowing device 9 is used, the average wind speed is too weak at 0.6 m / s and the turbulence rate exceeds ± 20%, which is consistent with the result of the questionnaire survey on skin sensation. It turns out that ventilation efficiency is good and the user does not feel cold when the air flow blowing device 9 is used and the average wind speed at the circled numeral 1 is 0.8 m / s to 1.0 m / s. It was.
In addition, since the washing space 2 is a closed space, a sufficient ventilation effect can be obtained only by installing the uniform air flow blowing device 9. However, if an exhaust device is provided at the exhaust port 10, the ventilation efficiency is further increased.
[0037]
【The invention's effect】
According to the first aspect of the present invention, since the heated strongly acidic water is discharged from the shower, the whole body can be washed and sterilized without feeling uncomfortable even when the temperature is low, and water is sprayed through a hose or a cock. Compared to what you do, it is easier to clean a wider area and use less water.
In addition, the sterilizing effect of the strongly acidic water that has been scattered away from the spout while the whole body is being washed is not reduced.
