Description

本発明は一般家庭の浴室、公衆浴場、温泉施設などに設置される比較的小規模な浴槽に溜められた浴槽水の中に空気を混入することで、気泡を発生させる浴槽用気泡発生装置に関する。 The present invention relates to a bathtub bubble generator that generates bubbles by mixing air into bathtub water stored in a relatively small bathtub installed in a bathroom, public bath, hot spring facility, etc. of a general household. ..

入浴中の浴槽水の中に気泡を発生させると、入浴者の皮膚に適度の刺激が与えられ、マッサージ効果や疲労回復効果などが得られることが広く知られている。このため、従来から様々な方式の浴槽用気泡発生装置が開発されている。 It is widely known that when air bubbles are generated in the bathtub water during bathing, the skin of the bather is appropriately stimulated, and a massage effect and a fatigue recovery effect can be obtained. For this reason, various types of bubble generators for bathtubs have been conventionally developed.

例えば、特開２００４-８９３９１号公報には、浴槽の底部に敷いたマットに浴槽の外に設置したポンプから空気を供給し、マットに形成した多数の小孔から空気を噴出させることで、浴槽水の中に気泡を発生させる浴槽用気泡発生装置が開示されている。 For example, Japanese Patent Application Laid-Open No. 2004-89391 describes a bathtub by supplying air to a mat laid at the bottom of the bathtub from a pump installed outside the bathtub and ejecting air from a large number of small holes formed in the mat. A bubble generator for a bathtub that generates bubbles in water is disclosed.

また、特開平１１−１８８０７０号公報には、水中ポンプの吐出ノズル中にパイプを突出し、このパイプの先端を吐出口に向けて斜めに設け、パイプに空気導入チューブを接続した浴槽用気泡発生装置が開示されている。
この浴槽用気泡発生装置によれば、水中ポンプを浴槽内に設置し、作動させると吐出ノズルから吐出する浴槽水にパイプから流入する空気が混入して気泡が発生し、気泡とともに浴槽内に浴槽水が噴出する。 Further, in Japanese Patent Application Laid-Open No. 11-188070, a bathtub bubble generator in which a pipe is projected into a discharge nozzle of a submersible pump, the tip of the pipe is provided diagonally toward a discharge port, and an air introduction tube is connected to the pipe. Is disclosed.
According to this bathtub bubble generator, when a submersible pump is installed in the bathtub and operated, air flowing from the pipe is mixed with the bathtub water discharged from the discharge nozzle to generate bubbles, and the bathtub is filled with bubbles. Water spouts.

特開２００４−８９３９１号公報Japanese Unexamined Patent Publication No. 2004-89391 特開平１１−１８８０７０号公報Japanese Unexamined Patent Publication No. 11-188070

上記した従来の浴槽用気泡発生装置は、浴槽水の中に形成される気泡の径が大きいため、急速に浮上した後、浴槽水の水面で弾けて消失してしまう。そのため、浴槽水への酸素溶解量も少なく、また、入浴者の皮膚に与える刺激も小さいので、十分なマッサージ効果や、疲労回復効果が得られない。
本発明はかかる問題点に鑑み、浴槽水中に発生させる気泡を微細化し、もって優れたマッサージ効果や、疲労回復効果を得られる浴槽用気泡発生装置を提供することを目的とする。 In the conventional bubble generator for bathtubs described above, since the diameter of bubbles formed in the bathtub water is large, the bubbles rapidly ascend and then burst and disappear on the surface of the bathtub water. Therefore, the amount of oxygen dissolved in the bathtub water is small, and the irritation given to the skin of the bather is also small, so that a sufficient massage effect and fatigue recovery effect cannot be obtained.
In view of such a problem, it is an object of the present invention to provide a bathtub bubble generator capable of obtaining an excellent massage effect and a fatigue recovery effect by miniaturizing bubbles generated in bathtub water.

請求項１に記載の発明は、浴槽用気泡発生装置であって、浴槽の外に設置されるポンプと、ポンプの吸込口に接続された吸込側管路と、吸込側管路に接続された気液混合器と、ポンプの吐出口に設置された衝突部材と、ポンプの吐出口に接続された吐出側管路を備え、
浴槽中の浴槽水を、吸込側管路を通してポンプへ吸込み、吸い込んだ浴槽水をポンプから吐出側管路を通して浴槽中に吐出して浴槽とポンプとの間を循環させ、
吸込側管路を通る浴槽水の中に気液混合器から空気を混入して浴槽水の中に気泡を発生させ、
浴槽水の中の気泡が衝突部材に衝突するようにし、
ポンプの吐出口に拡径部と縮径部を形成するとともに、拡径部と縮径部の境界に段差面を形成し、
拡径部の中央部に前記衝突部材を設けて、衝突部材の周面に沿った流路を形成し、該流路を流れる浴槽水が段差面に当たった後に縮径部に流入するように拡径部と縮径部を連通させたことを特徴とする。 The invention according to claim 1 is a bubble generator for a bathtub, which is connected to a pump installed outside the bathtub, a suction side pipe connected to a suction port of the pump, and a suction side pipe. It is equipped with a gas-liquid mixer, a collision member installed at the discharge port of the pump, and a discharge side pipeline connected to the discharge port of the pump.
The bathtub water in the bathtub is sucked into the pump through the suction side pipeline, and the sucked bathtub water is discharged from the pump into the bathtub through the discharge side pipeline to circulate between the bathtub and the pump.
Air is mixed from the gas-liquid mixer into the bathtub water passing through the suction side pipeline to generate air bubbles in the bathtub water.
It bubbles in the bath water so as to impinge on the impact member,
An enlarged diameter portion and a reduced diameter portion are formed at the discharge port of the pump, and a stepped surface is formed at the boundary between the enlarged diameter portion and the reduced diameter portion.
The collision member is provided in the central portion of the enlarged diameter portion to form a flow path along the peripheral surface of the collision member so that the bath water flowing through the flow path hits the stepped surface and then flows into the reduced diameter portion. It is characterized in that the enlarged diameter portion and the reduced diameter portion are communicated with each other.

請求項２に記載の発明は、請求項１に記載の浴槽用気泡発生装置において、
吐出側管路中にエゼクタを設け、エゼクタに空気供給管を接したことを特徴とする。 The invention according to claim 2 is the air bubble generator for a bathtub according to claim 1.
It is characterized in that an ejector is provided in the discharge side pipeline and the air supply pipe is in contact with the ejector.

請求項１に記載の発明によれば、気液混合器で空気を混入して発生させた浴槽中の気泡が衝突部材に当たって微細気泡になるので、マッサージ効果や疲労回復効果を高めることができる。
そして、浴槽水の中の気泡が衝突部材に当たって生じた微細気泡が、さらに段差面に当たることで、より微細化する。 According to the invention of claim 1, since the bubbles in the bathtub generated by mixing air in the gas-liquid mixer hit the collision member and become fine bubbles, the massage effect and the fatigue recovery effect can be enhanced.
Then, the fine bubbles generated by the bubbles in the bath water hitting the collision member further hit the stepped surface, so that the bubbles become finer.

請求項２に記載の発明によれば、循環する浴槽水の中に気液混合器から空気が混入するのに加え、エゼクタによって浴槽水の圧力が低下し、それに伴い空気供給管から空気が吸引されて混入するので、浴槽水中に多量の気泡が発生し、酸素溶解量も増大し、よりマッサージ効果や疲労回復効果を高めることができる。 According to the invention of claim 2 , in addition to air being mixed into the circulating bathtub water from the gas-liquid mixer, the pressure of the bathtub water is lowered by the ejector, and the air is sucked from the air supply pipe accordingly. As a result, a large amount of air bubbles are generated in the bathtub water, the amount of oxygen dissolved increases, and the massage effect and the fatigue recovery effect can be further enhanced.

請求項３に記載の発明によれば、浴槽水を循環させるポンプにギヤポンプを使用するので、気液混合器で空気を混入して発生させた浴槽中の気泡がギヤポンプのギヤロータによって微細化され、微細気泡となる。そのため、よりマッサージ効果や疲労回復効果を高めることができる。 According to the third aspect of the present invention, since the gear pump is used as the pump for circulating the bathtub water, the bubbles in the bathtub generated by mixing air in the gas-liquid mixer are refined by the gear rotor of the gear pump. It becomes fine bubbles. Therefore, the massage effect and the fatigue recovery effect can be further enhanced.
