Description

本発明は、空気配管の消音装置に関する。 The present invention relates to a silencer for an air pipe.

従来、酸素富化装置で発生した高酸素濃度の空気を浴室内に供給するようにしたものがある（特許文献１参照）。   2. Description of the Related Art Conventionally, there is one that supplies high oxygen concentration air generated by an oxygen enrichment apparatus into a bathroom (see Patent Document 1).

これは、浴室内に蒸気や熱気がこもり、呼吸が息苦しく感じられることから、酸素富化装置で発生した高酸素濃度の空気を浴室内に供給して、呼吸の息苦しさを無くすことで快適に入浴できるようにしたものである。   This is because steam and hot air are trapped in the bathroom, and breathing feels stuffy, so it is comfortable by supplying high oxygen concentration air generated by the oxygen enricher into the bathroom and eliminating breathing stuffiness. It is designed for bathing.

前記酸素富化装置は、一般的には浴室の天井パネルの外上部に設置して、高酸素濃度の空気を浴室内に供給するための空気供給ノズルは、浴室の側壁パネルや浴槽のエプロン内に設けている。   The oxygen enrichment device is generally installed on the outer top of the ceiling panel of the bathroom, and the air supply nozzle for supplying air with high oxygen concentration into the bathroom is provided in the side wall panel of the bathroom or the apron of the bathtub. Provided.

Japanese Utility Model Publication No. 7-51563 JP-A-11-33071

しかしながら、酸素富化装置で発生した高酸素濃度の空気を浴室内に供給するためのポンプとして、脈動を生じる容積型ポンプを使用した場合、高酸素濃度の空気に含まれる脈動に伴う騒音が配管から天井パネルを経て浴室内に伝わるとともに、配管を通って空気供給ノズルから浴室内に伝わるという問題があった。また、騒音の低減のための消音装置として、金属製のものが一般的であるが、消音効果を高めるために、大型になりやすいという問題があった。   However, when a positive displacement pump that generates pulsation is used as a pump for supplying high oxygen concentration air generated in the oxygen enrichment device into the bathroom, noise accompanying the pulsation contained in the high oxygen concentration air is piped. In addition to being transmitted through the ceiling panel to the bathroom, there was a problem of being transmitted through the piping from the air supply nozzle into the bathroom. Further, a metal silencer for reducing noise is generally used, but there is a problem that it tends to be large in order to enhance the silencing effect.

本発明は、前記問題を解消するためになされたもので、空気の脈動に伴う騒音をコンパクトな構造で効果的に低減できるようにした空気配管の消音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 made to solve the above problems, and it is an object of the present invention to provide an air pipe silencer capable of effectively reducing noise accompanying air pulsation with a compact structure. is there.

前記課題を解決するために、本発明は、浴室の天井パネルの外上部に設置された酸素富化装置で発生した高酸素濃度の空気を空気配管から浴室内の空気供給用ノズルに供給するものであり、前記酸素富化装置の吐出口直後の空気配管に対して、有底円筒状の消音本体を設け、この消音本体の上部開口を弾性蓋材で気密に閉塞して、消音本体の内部に、空気配管の内径よりも大径の消音空間部を設ける一方、前記消音本体の下部の中央部には、略水平方向から略垂直方向へＬ字形状に屈曲する流入部を形成して、前記消音空間部の弾性蓋材の中央部に対して、略垂直（略直角）方向から空気を流入させるようにし、前記消音本体の下部の周囲部には、略水平方向から略垂直方向へＬ字形状に屈曲する流出部を形成して、前記消音空間部の弾性蓋材の周囲部に対して、略垂直（略直角）方向から空気を流出させるようにしていることを特徴とする空気配管の消音装置を提供するものである。 In order to solve the above-mentioned problems, the present invention supplies high oxygen concentration air generated by an oxygen enrichment device installed on the outer top of a bathroom ceiling panel from an air pipe to an air supply nozzle in the bathroom. A bottomed cylindrical silencer main body is provided for the air pipe immediately after the discharge port of the oxygen enricher, and the upper opening of the silencer main body is airtightly closed with an elastic lid, In addition, while providing a silencing space portion having a diameter larger than the inner diameter of the air pipe, an inflow portion that is bent in an L shape from a substantially horizontal direction to a substantially vertical direction is formed in the central portion of the lower portion of the silencing body, Air is allowed to flow from a substantially vertical (substantially right angle) direction to the central portion of the elastic lid member of the muffler space portion, and the peripheral portion of the lower portion of the muffler main body is shifted from a substantially horizontal direction to a substantially vertical direction. Forming an outflow portion that bends in a letter shape, and an elastic lid for the silencing space portion The surrounding portion of the one in which to provide a noise suppressor of the air pipe, characterized in that so as to flow out the air from a substantially vertical (substantially perpendicular) direction.

本発明によれば、空気配管に介設した消音装置の消音本体の上部開口を弾性蓋材で気密に閉塞して、消音本体の内部に、空気配管の内径よりも大径の消音空間部を設けたから、弾性蓋材が空気の脈動流で振動して騒音エネルギーを減衰するので、空気の脈動に伴う騒音を効果的に低減できるようになる。また、騒音エネルギーを弾性蓋材の振動で減衰させるので、消音装置自体がコンパクトな構造であっても消音効果を高めることができる。 According to the present invention, the upper opening of the silencer body of the silencer interposed in the air pipe is hermetically closed with the elastic lid member, and the silencer space having a larger diameter than the inner diameter of the air pipe is formed inside the silencer body. Since the elastic lid member vibrates with the pulsating flow of air and attenuates noise energy, the noise accompanying the pulsating air can be effectively reduced. Further, since the noise energy is attenuated by the vibration of the elastic lid member, the silencing effect can be enhanced even if the silencing device itself has a compact structure.

また、消音空間部の弾性蓋材で構成した部分に対して、流入部より略垂直方向から空気を流入させるようにしたから、空気の脈動流が流入部から弾性蓋材の中央部に直に当たるから、騒音エネルギーの減衰効率が向上するようになる。In addition, since air is allowed to flow from the inflow portion in a substantially vertical direction with respect to the portion constituted by the elastic lid member of the sound deadening space portion, the pulsating flow of air directly hits the central portion of the elastic lid material from the inflow portion. Therefore, the noise energy attenuation efficiency is improved.

さらに、消音空間部の弾性蓋材で構成した部分に対して、流出部より略垂直方向から空気を流出させるようにしたから、騒音エネルギーが減衰された空気が弾性蓋材から流出部に直に出るから、騒音エネルギーの減衰効率に悪影響が与えられにくくなる。Furthermore, since the air is allowed to flow out from the outflow portion in a substantially vertical direction with respect to the portion constituted by the elastic lid member of the sound deadening space portion, the air whose noise energy has been attenuated directly flows from the elastic lid material to the outflow portion. Therefore, it is difficult to adversely affect the attenuation efficiency of noise energy.

さらにまた、酸素富化装置の吐出口直後の空気配管に消音装置を設けて、この消音装置の消音本体の消音空間部の上部に弾性蓋材を設け、この消音空間部の下部に流入部および流出部を形成したから、酸素富化装置の吐出口付近で結露した高酸素濃度の空気の結露水が流入部から消音空間部内に入っても、下部の流出部から直ちに排出されて消音空間部内に溜まらないので、騒音エネルギーの減衰効率に悪影響を与えにくくなる。Furthermore, a silencer is provided in the air pipe immediately after the discharge port of the oxygen enricher, and an elastic lid member is provided in the upper part of the silencer space of the silencer body of the silencer, and an inflow portion and a lower part of the silencer space are provided. Since the outflow part is formed, even if condensed water of high oxygen concentration air condensed near the discharge port of the oxygen enrichment device enters the silencing space part from the inflow part, it is immediately discharged from the lower outflow part and enters the silencing space part. Therefore, it is difficult to adversely affect the attenuation efficiency of noise energy.

この結果、高酸素濃度の空気に含まれる脈動に伴う騒音が酸素富化装置の空気配管を通って空気供給ノズルから浴室内に伝わりにくくなるので、浴室内が静寂になる。As a result, noise accompanying the pulsation contained in the air with high oxygen concentration is less likely to be transmitted from the air supply nozzle into the bathroom through the air pipe of the oxygen enricher, so that the interior of the bathroom becomes quiet.

また、騒音が空気配管から天井パネルを経て浴室内に伝わりにくくなるので、この点からも浴室内が静寂になる。In addition, noise is less likely to be transmitted from the air piping through the ceiling panel and into the bathroom, which also makes the interior of the bathroom quiet.

以下、本発明を実施するための最良の形態について、図面を参照しながら詳細に説明する。   Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

図１に示すように、浴室１の下部の一側には浴槽２が設置され、他側を洗い場３としている。浴室１の四周囲は側壁パネル（具体的に図示せず。）で取り囲まれ、その上部に天井パネル４が取付けられている。前記側壁パネルの一部に出入り用扉が設けられている。   As shown in FIG. 1, a bathtub 2 is installed on one side of the lower part of the bathroom 1, and the other side is a washing place 3. The four surroundings of the bathroom 1 are surrounded by side wall panels (not shown specifically), and a ceiling panel 4 is attached to the upper part thereof. An entrance door is provided in a part of the side wall panel.

前記天井パネル４の外上部には酸素富化装置５が設置されている。この酸素富化装置５は、具体的に図示しないが、酸素富化膜と真空ポンプ（脈動を生じる容積型ポンプ）とで構成され、真空ポンプで大気中の空気を取入れて有機高分子の平膜からなる酸素富化膜に空気を通すときに、酸素と窒素は減速するが、酸素は窒素の２．５倍の速度で通過する。これにより、通常の空気は窒素が７８％、酸素が２１％であったのが、酸素富化膜によって、窒素が６９％、酸素が３０％の空気となり、酸素が富化された高酸素濃度の空気を得ることができる。   An oxygen enrichment device 5 is installed on the outer top of the ceiling panel 4. Although not specifically shown, the oxygen-enriching device 5 is composed of an oxygen-enriched film and a vacuum pump (a positive displacement pump that generates pulsation). When air is passed through an oxygen-enriched membrane consisting of a membrane, oxygen and nitrogen decelerate, but oxygen passes at a rate 2.5 times that of nitrogen. As a result, the normal air was 78% nitrogen and 21% oxygen, but the oxygen-enriched film made the air 69% nitrogen and 30% oxygen, and the oxygen-enriched high oxygen concentration Can get the air.

前記酸素富化装置５の高酸素濃度の空気の吐出口５ａには、３本の空気配管６〜８が接続されている。なお、前記吐出口５ａに１本の空気配管を接続して、これから３本の空気配管６〜８に分岐する等しても良く、要するに、空気配管６〜８に高酸素濃度の空気をそれぞれ供給できれば良い。 Three air pipes 6 to 8 are connected to the discharge port 5 a for the high oxygen concentration air of the oxygen enricher 5. It should be noted that one air pipe may be connected to the discharge port 5a and then branched into three air pipes 6-8. In short, high oxygen concentration air is respectively supplied to the air pipes 6-8. It only needs to be supplied.

前記空気配管６は、吐出口５ａの直後に消音装置（サイレンサー）９（Ａ，Ｂ）を介設して、浴室１の天井パネル４に開けた取付け穴４ａに差し込んで取付けた空気供給ノズル１０の入口側に差し込んで接続している。この空気供給ノズル１０の出口側は、浴室１内の浴槽２の上方に臨むようになる。 The air pipe 6 is provided with a silencer (silencer) 9 (A, B) immediately after the discharge port 5a, and is inserted into a mounting hole 4a formed in the ceiling panel 4 of the bathroom 1 and attached thereto. It is plugged into the entrance side of and connected. The outlet side of the air supply nozzle 10 faces the bathtub 2 in the bathroom 1.

本実施形態では、酸素富化装置５の吐出口５ａと空気供給ノズル１０とを接続する空気配管６だけに消音装置９（Ａ，Ｂ）を介設したものであるが、空気配管７，８にもそれぞれ消音装置９（Ａ，Ｂ）を介設することもでき、また前記吐出口５ａに接続した１本の空気配管から３本の空気配管６〜８に分岐する場合には、分岐前の１本の空気配管に消音装置９（Ａ，Ｂ）を介設することもできる。 In the present embodiment, the silencer 9 (A, B) is interposed only in the air pipe 6 that connects the discharge port 5a of the oxygen enrichment apparatus 5 and the air supply nozzle 10, but the air pipes 7, 8 are used. In addition, a silencer 9 (A, B) can also be provided, and when one air pipe connected to the discharge port 5a is branched into three air pipes 6 to 8, before the branching The silencer 9 (A, B) can be interposed in one air pipe .

図２および図３は、前記消音装置９（Ａ，Ｂ）の内、具体的な第１実施形態の構造である。第１実施形態の消音装置９（Ａ）は、有底円筒状の消音本体９ａの上部開口を弾性体、例えばゴム製の弾性蓋材９ｂで気密に閉塞して、消音本体９ａの内部に、空気配管６の内径よりも大径の消音空間部９ｃを設けている。なお、消音本体９ａは、厚手のゴム製であるのが好ましいが、金属製や合成樹脂製であっても良い。 2 and 3 show a specific structure of the first embodiment of the silencer 9 (A, B). The silencing device 9 (A) of the first embodiment is such that the upper opening of the bottomed cylindrical silencing body 9a is airtightly closed with an elastic body, for example, an elastic lid member 9b made of rubber, inside the silencing body 9a. A silencer space 9c having a diameter larger than the inner diameter of the air pipe 6 is provided. The muffler body 9a is preferably made of thick rubber, but may be made of metal or synthetic resin.

前記消音本体９ａの下部の中央部には、略水平方向から略垂直方向へＬ字形状に屈曲する流入部９ｄを形成して、消音空間部９ｃの弾性蓋材９ｂの中央部に対して、略垂直（略直角）方向ａから空気を流入させるようにしている。 An inflow portion 9d that bends in an L shape from a substantially horizontal direction to a substantially vertical direction is formed in the central portion of the lower portion of the silencing main body 9a, and with respect to the central portion of the elastic lid member 9b of the silencing space portion 9c, Air is allowed to flow in from a substantially vertical (substantially right angle) direction a.

また、前記消音本体９ａの下部の周囲部には、略水平方向から略垂直方向へＬ字形状に屈曲する流出部９ｅを形成して、消音空間部９ｃの弾性蓋材９ｂの周囲部に対して、略垂直（略直角）方向ｂから空気を流出させるようにしている。 In addition, an outflow portion 9e that bends in an L shape from a substantially horizontal direction to a substantially vertical direction is formed in a lower peripheral portion of the silencer main body 9a, and is formed with respect to a peripheral portion of the elastic lid member 9b of the silencer space portion 9c. Thus, air is allowed to flow out from a substantially vertical (substantially right angle) direction b.

第１実施形態の消音装置９（Ａ）では、空気配管６に介設した消音装置９（Ａ）の消音空間部９ｃの少なくとも一部を、弾性体である弾性蓋材９ｂで構成したから、弾性蓋材９ｂが空気の脈動流で振動して騒音エネルギーを減衰するので〔図３（ａ）は、正圧の脈動流ｃで弾性蓋材９ｂがふくらむ方向に振動した状態、図３（ｃ）は、負圧の脈動流ｄで弾性蓋材９ｂがへこむ方向に振動した状態〕、空気の脈動に伴う騒音を効果的に低減できるようになる。また、騒音エネルギーを弾性蓋材９ｂの振動で減衰させるので、消音装置９（Ａ）自体がコンパクトな構造であっても消音効果を高めることができる。 In the silencer 9 (A) of the first embodiment, at least a part of the silencer space 9c of the silencer 9 (A) interposed in the air pipe 6 is configured by an elastic lid member 9b that is an elastic body. Since the elastic lid member 9b vibrates with the pulsating flow of air and attenuates the noise energy [FIG. 3 (a) shows a state where the elastic lid member 9b vibrates in the direction of swelling with the positive pressure pulsating flow c, FIG. ) Is a state in which the elastic lid member 9b vibrates in the direction of depression due to the pulsating flow d of negative pressure], and noise associated with air pulsation can be effectively reduced. Further, since the noise energy is attenuated by the vibration of the elastic lid member 9b, the silencing effect can be enhanced even if the silencing device 9 (A) itself has a compact structure.

また、消音空間部９ｃの弾性蓋材９ｂで構成した部分に対して、流入部９ｄより略垂直方向ａから空気を流入させるようにしたから、空気の脈動流が流入部９ｂから弾性蓋材９ｂの中央部に直に当たるから、騒音エネルギーの減衰効率が向上するようになる。 Further, since air is caused to flow from the inflow portion 9d in the substantially vertical direction a to the portion constituted by the elastic lid member 9b of the silencer space portion 9c, the pulsating flow of air flows from the inflow portion 9b to the elastic lid material 9b. The noise energy attenuation efficiency is improved because it directly hits the central portion of the noise.

さらに、消音空間部９ｃの弾性蓋材９ｂで構成した部分に対して、流出部９ｅより略垂直方向ｂから空気を流出させるようにしたから、騒音エネルギーが減衰された空気が弾性蓋材９ｂから流出部９ｅに直に出るから、騒音エネルギーの減衰効率に悪影響が与えられにくくなる。 Furthermore, the configuration portion of an elastic lid 9b of silencing space portion 9c, it is so arranged to flow out air from a substantially vertical direction b than the outflow section 9e, air noise energy is attenuated from the elastic lid 9b Since it goes out to the outflow part 9e directly, it becomes difficult to have a bad influence on the attenuation efficiency of noise energy.

さらにまた、酸素富化装置５の吐出口５ａ直後の空気配管６に消音装置９（Ａ）を設けて、この消音装置９（Ａ）の消音本体９ａの消音空間部９ｃの上部に弾性蓋材９ｂを設け、この消音空間部９ｃの下部に流入部９ｄおよび流出部９ｅを形成したから、酸素富化装置５の吐出口５ａ付近で結露した高酸素濃度の空気の結露水が流入部９ｄから消音空間部９ｃ内に入っても、下部の流出部９ｅから直ちに排出されて消音空間部９ｃ内に溜まらないので、騒音エネルギーの減衰効率に悪影響を与えにくくなる。 Furthermore, a silencer 9 (A) is provided in the air pipe 6 immediately after the discharge port 5a of the oxygen enricher 5, and an elastic cover member is provided above the silencer space 9c of the silencer body 9a of the silencer 9 (A). 9b is provided, and the inflow portion 9d and the outflow portion 9e are formed in the lower part of the silencing space portion 9c. Therefore, condensed water of high oxygen concentration air condensed near the discharge port 5a of the oxygen enrichment device 5 is discharged from the inflow portion 9d Even if it enters the silencing space portion 9c, it is immediately discharged from the lower outflow portion 9e and does not accumulate in the silencing space portion 9c, so that it is difficult to adversely affect the attenuation efficiency of noise energy.

この結果、高酸素濃度の空気に含まれる脈動に伴う騒音が酸素富化装置５の空気配管６を通って空気供給ノズル１０から浴室１内に伝わりにくくなるので、浴室１内が静寂になる。 As a result, noise accompanying pulsation contained in the air with a high oxygen concentration is less likely to be transmitted from the air supply nozzle 10 into the bathroom 1 through the air pipe 6 of the oxygen enrichment device 5, so that the interior of the bathroom 1 becomes quiet.

また、騒音が空気配管６から天井パネル４を経て浴室１内に伝わりにくくなるので、この点からも浴室１内が静寂になる。 In addition, since it becomes difficult for noise to be transmitted from the air pipe 6 through the ceiling panel 4 into the bathroom 1, the interior of the bathroom 1 is also quiet from this point.

図４は、前記消音装置９（Ａ，Ｂ）の内、具体的な第２実施形態の構造である。第２実施形態の消音装置９（Ｂ）は、円筒状の消音本体９ｆの両端部に流入部９ｇと流出部９ｈとをそれぞれ一体的に形成して、消音本体９ｆの内部に、空気配管６の内径よりも大径の消音空間部９ｉを設けたものであり、全体が弾性体、例えばゴム製である。なお、消音本体９ｆの両端部や流入部９ｇ、流出部９ｈは、金属製や合成樹脂製であっても良い。 FIG. 4 shows a specific structure of the second embodiment of the silencer 9 (A, B). In the silencer 9 (B) of the second embodiment, an inflow portion 9g and an outflow portion 9h are integrally formed at both ends of a cylindrical silencer main body 9f, and the air pipe 6 is provided inside the silencer main body 9f. The sound deadening space 9i having a diameter larger than the inner diameter is provided, and the whole is made of an elastic body, for example, rubber. In addition, both ends of the silencer main body 9f, the inflow portion 9g, and the outflow portion 9h may be made of metal or synthetic resin.

第２実施形態の消音装置９（Ｂ）では、空気配管６に介設した消音装置９（Ｂ）の少なくとも消音本体９ｆを弾性体で構成したから、消音本体９ｆの壁部分が空気の脈動流で振動して騒音エネルギーを減衰するので〔符号ｅは、正圧の脈動流で消音本体９ｆがふくらむ方向に振動した状態、符号ｆは、負圧の脈動流で消音本体９ｆがへこむ方向に振動した状態〕、空気の脈動に伴う騒音を効果的に低減できるようになる。また、騒音エネルギーを消音本体９ｆの壁部分の振動で減衰させるので、消音装置９（Ｂ）自体がコンパクトな構造であっても消音効果を高めることができる。 In the silencer 9 (B) of the second embodiment, since at least the silencer body 9f of the silencer 9 (B) interposed in the air pipe 6 is made of an elastic body, the wall portion of the silencer body 9f is a pulsating flow of air. The noise energy is attenuated by the vibration [sign e is a state in which the silencing body 9f vibrates in a positive pressure pulsating flow, and the symbol f is a vibration in a direction in which the silencing main body 9f is recessed due to negative pressure pulsating flow The noise accompanying air pulsation can be effectively reduced. Further, since the noise energy is attenuated by the vibration of the wall portion of the silencing body 9f, the silencing effect can be enhanced even if the silencing device 9 (B) itself has a compact structure.

前記酸素富化装置５の高酸素濃度の空気の吐出口５ａの空気配管６は、前記空気供給ノズル１０に接続しているが、残り２本の空気配管７，８は、図１のように、浴室１の外方を側壁パネルに沿わせて垂れ下がらせて、浴槽２側に設置した微細気泡発生装置Ａとジェットバス装置Ｂとにそれぞれ接続している。 The air pipe 6 of the high oxygen concentration air outlet 5a of the oxygen enricher 5 is connected to the air supply nozzle 10, but the remaining two air pipes 7 and 8 are as shown in FIG. The outside of the bathroom 1 hangs down along the side wall panel and is connected to the fine bubble generator A and the jet bath apparatus B installed on the bathtub 2 side, respectively.

図５（ａ）に示すように、微細気泡発生装置Ａは、浴槽２の浴槽壁２ａに吸込口１７と吐出口１８とが形成されて、吸込口１７は、空気配管１９を介して空気吸引部（エゼクタ−）２０の入口に接続され、この空気吸引部２０の出口は、空気配管２１を介してポンプ２２に接続されている。前記空気吸引部２０の側部には、前記酸素富化装置５の空気配管７が接続されている。 As shown in FIG. 5 (a), the fine bubble generating device A has a suction port 17 and a discharge port 18 formed in the bathtub wall 2 a of the bathtub 2, and the suction port 17 is sucked through an air pipe 19. The outlet of the air suction unit 20 is connected to a pump 22 via an air pipe 21. An air pipe 7 of the oxygen enrichment device 5 is connected to a side portion of the air suction unit 20.

前記ポンプ２２は、空気配管２３を介して気液溶解タンク２４の上部に設けられた噴霧ノズル２５に接続されていて、この気液溶解タンク２４には、空気抜き弁２６が設けられている。 The pump 22 is connected to a spray nozzle 25 provided on the upper part of the gas-liquid dissolution tank 24 through an air pipe 23, and an air vent valve 26 is provided in the gas-liquid dissolution tank 24.

前記気液溶解タンク２４の下部は、空気配管２７を介して前記吐出口１８に接続され、この吐出口１８には、減圧弁である微細気泡発生ノズル２８が設置されている。 A lower part of the gas-liquid dissolution tank 24 is connected to the discharge port 18 through an air pipe 27, and a fine bubble generating nozzle 28 that is a pressure reducing valve is installed in the discharge port 18.

そして、スイッチ操作でポンプ２２を駆動すれば、吸込口１７から空気配管１９，２１を介して浴槽２内の浴水がポンプ２２に吸水されるとともに、その途中で、空気吸引部（エゼクタ−）２０の負圧作用により、空気配管７を介して酸素富化装置５から取入れられた高酸素濃度の空気が浴水に混入されるようになる。 And if the pump 22 is driven by switch operation, the bath water in the bathtub 2 will be absorbed by the pump 22 via the air piping 19 and 21 from the suction inlet 17, and an air suction part (ejector) in the middle of that Due to the negative pressure action of 20, high oxygen concentration air taken in from the oxygen enrichment device 5 through the air pipe 7 is mixed into the bath water.

この空気が混入された浴水は、ポンプ２２から空気配管２３を介して噴霧ノズル２５から気液溶解タンク２４内に噴出されることでバブリング状態となる。この気液溶解タンク２４内の余剰空気は、空気抜き弁２６からタンク外部に排出される。 The bath water mixed with this air is bubbled from the spray nozzle 25 into the gas-liquid dissolution tank 24 through the air pipe 23 from the pump 22. Excess air in the gas-liquid dissolution tank 24 is discharged from the air vent valve 26 to the outside of the tank.

この気液溶解タンク２４内の浴水は、空気配管２７を介して微細気泡発生ノズル２８で白濁の濃い微細気泡を含む浴水に変換されながら、吐出口１８から浴槽２内に吐出されるようになる。 The bath water in the gas-liquid dissolution tank 24 is discharged from the discharge port 18 into the bathtub 2 while being converted into bath water containing white cloudy fine bubbles by the fine bubble generating nozzle 28 via the air pipe 27. become.

このような浴水の循環を繰り返すことで浴槽２内は、微細気泡の浴水で満たされるようになる。   By repeating such circulation of the bath water, the inside of the bathtub 2 is filled with bath water with fine bubbles.

図５（ｂ）に示すように、ジェットバス装置Ｂは、浴槽２の浴槽壁２ａに吸込口３３と吐出口３４とが形成され、この吸込口３３と吐出口３４とは、ジェットポンプ３６を有する空気配管３５で接続されている。前記吐出口３４に設置されたジェットノズル３２には、前記酸素富化装置５の空気配管８が接続されている。 As shown in FIG. 5 (b), the jet bath apparatus B has a suction port 33 and a discharge port 34 formed in the bathtub wall 2 a of the bathtub 2, and the suction port 33 and the discharge port 34 connect the jet pump 36. It is connected by an air pipe 35 having it. An air pipe 8 of the oxygen enricher 5 is connected to the jet nozzle 32 installed at the discharge port 34.

そして、スイッチ操作でジェットポンプ３６を駆動すれば、吸込口３３から空気配管３５を介して浴槽２内の浴水がジェットポンプ３６で吸水されながら、吐出口３４から浴槽２内に噴射吐出されるようになる。このとき、吐出口３４のジェットノズル３２の負圧作用により、空気配管８を介して酸素富化装置５から取入れられた高酸素濃度の空気が浴水に混入されるので、吐出口３４からは比較的大きな気泡を含んだ浴水が強く噴射されるようになる。 When the jet pump 36 is driven by a switch operation, bath water in the bathtub 2 is jetted and discharged from the discharge port 34 into the bathtub 2 while being sucked by the jet pump 36 through the air pipe 35 from the suction port 33. It becomes like this. At this time, air of high oxygen concentration taken in from the oxygen enricher 5 through the air pipe 8 is mixed into the bath water by the negative pressure action of the jet nozzle 32 of the discharge port 34, so Bath water containing relatively large bubbles is strongly jetted.

前記微細気泡発生装置Ａとジェットバス装置Ｂとは、浴槽２にそれぞれ設置して、選択的に使用することができるが、いずれか一方のみであっても良い。   The fine bubble generating device A and the jet bath device B can be installed in the bathtub 2 and used selectively, but only one of them may be used.

そして、酸素富化装置５で発生した高酸素濃度の空気を空気配管７，８で微細気泡発生ノズル２８またはジェットノズル３２で浴槽２内に供給する際に、空気配管７，８に消音装置９（Ａ，Ｂ）を設けてあれば、騒音が酸素富化装置５の空気配管７，８を通って微細気泡発生ノズル２８またはジェットノズル３２から浴槽２内を通って浴室１内に伝わりにくくなるので、浴室１内が静寂になる。また、騒音が空気配管７，８から天井パネル４や側壁パネルを経て浴室１内に伝わりにくくなるので、この点からも浴室１内が静寂になる。 Then, the high oxygen concentration of air generated by the oxygen enrichment device 5 when supplied into the tub 2 in the air piping 7,8 fine bubble generating nozzle 28 or jet nozzle 32, the muffler to the air piping 7, 8 9 If (A, B) is provided, it becomes difficult for noise to be transmitted from the fine bubble generating nozzle 28 or the jet nozzle 32 through the bathtub 2 to the bathroom 1 through the air pipes 7 and 8 of the oxygen enricher 5. Therefore, the inside of the bathroom 1 becomes quiet. In addition, noise is difficult to be transmitted from the air pipes 7 and 8 to the bathroom 1 through the ceiling panel 4 and the side wall panel, so that the interior of the bathroom 1 is also quiet from this point.

前記実施形態は、浴室１に設置した酸素富化装置５の空気配管６〜７に介設した消音装置９（Ａ，Ｂ）であったが、これに限られるものではなく、空気配管の途中に介設する消音装置（サイレンサー）として、他の分野でも広く適用できることは言うまでもない。 Although the said embodiment was the silencer 9 (A, B) interposed in the air piping 6-7 of the oxygen enrichment apparatus 5 installed in the bathroom 1, it is not restricted to this, The middle of an air piping Needless to say, the present invention can be widely applied in other fields as a silencer interposed between the two.
