Description

  The present invention relates to a bathtub with a microbubble generator that generates fine bubbles in bath water so that bathing can be performed comfortably.

  In recent years, a microbubble generator has been installed in the bathtub to dissolve the air in the bath water sucked from the bathtub, and discharge the bath water in which the air is dissolved into the bathtub to generate microbubbles in the bath water of the bathtub. A bathtub with a microbubble generator is provided (for example, see Patent Document 1). In such a bathtub with a fine bubble generator, a thermal effect is obtained because bathing is performed in bath water in which fine bubbles are generated, but air in the atmosphere (21% oxygen concentration) is simply dissolved in the bath water. However, since only fine bubbles are generated, skin respiration is not promoted so much, and the burden of comfort and cardiopulmonary function is not reduced.

Therefore, oxygen enriched air supplied from the oxygen enricher is generated in the bath water as microbubbles by the microbubble generator using an oxygen enricher that generates high oxygen concentration air, so-called oxygen enriched air. Thus, it is considered that the skin breathing is promoted to improve the comfort level and reduce the burden on the cardiopulmonary function. The oxygen-enriched air produced by the oxygen-enriched device not only dissolves in the bath water and promotes skin respiration, but if it is discharged into the air, the oxygen concentration in the air increases, resulting in lung respiration. The burden of cardiopulmonary function is also reduced. Therefore, in addition to generating oxygen-enriched air as fine bubbles in the bath water with a micro-bubble generator, for example, the oxygen-enriched air is once discharged into the bath water by mixing it with a jet from a jet bath device and finally Therefore, what can be discharged into the bathroom or directly into the bathroom has been desired.

  The present invention has been invented in view of the above-described conventional problems, and the object of the present invention is to provide oxygen-enriched air supplied from an oxygen-enriching device in microbubbles in bath water using a fine-bubble generator. It is an object of the present invention to provide a bathtub with a fine bubble generator that can discharge oxygen-enriched air into the bathroom without going through the fine bubble generator.

  In order to solve the above problems, a bathtub with a microbubble generator of the present invention is a microbubble composed of an oxygen enricher 1 that generates oxygen-enriched air and oxygen-enriched air supplied from the oxygen enricher 1.

Therefore, it is possible to reduce the burden of cardiopulmonary function during pulmonary breathing and improve the comfort level, or it is possible to reduce the burden of cardiopulmonary function during skin breathing and pulmonary breathing by combining these Become.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 1, a waterproof floor pan P is provided on the bottom surface in a bathroom BR formed of a unit bathroom, and a bathtub BT is provided on the waterproof floor pan P. The bathtub BT is provided with a fine bubble generating device 2 that generates fine bubbles by discharging the bath water in which the air is dissolved in the bath water sucked from the bathtub BT and into the bathtub BT. In addition, the bathtub BT is provided with a jet bath device 6 that entrains air into the bath water sucked from the bathtub BT and jets the bath water containing air into the bathtub BT.

  As shown in FIG. 2, the microbubble generator 2 mainly includes a suction port 21, a discharge port 22, a circulation conduit 23, an ejector 24, a circulation pump 25, and a dissolution tank 26. The suction port 21 is formed at the bottom of the bathtub BT, and sucks the bath water in the bathtub BT. The discharge port 22 is formed at the bottom of the bathtub BT, and bath water containing fine bubbles is discharged from the discharge port 22 into the bathtub BT. The suction port 21 and the discharge port 22 communicate with each other through a circulation line 23 piped outside the bathtub BT. A circulation pump 25 is disposed in the middle of the circulation line 23 to drive the circulation pump 25. Accordingly, the bath water is sucked from the suction port 21 and discharged from the discharge port 22. In addition, an ejector 24 is provided in the circulation line 23 so as to be positioned between the suction port 21 and the circulation pump 25, and when the bath water passes through the ejector 24 by driving of the circulation pump 25, the oxygen enricher 1 described later. The oxygen-enriched air supplied through the supply path 3 and the first branch path 3a is sucked in to mix air in the bath water. A dissolution tank 26 is disposed in the circulation line 23 between the circulation pump 25 and the discharge port 22, and the air mixed by the ejector 24 is dissolved in the bath water. In the dissolution tank 26, the bath water is passed through a meandering path so that air is dissolved in the bath water. The discharge port 22 decompresses and discharges the bath water in which the air is dissolved, so that the dissolved air becomes fine bubbles, and the bath water containing the fine bubbles is discharged. The bath water is so-called milky. You can take a bath.

  As shown in FIG. 3, the jet bath device 6 mainly includes a suction port 61, a jet port 62, a circulation pipe 63, a jet pump 64, an air intake port 65, and an air supply pipe 66. The suction port 61 is formed in the side wall of the bathtub BT, and the bath water in the bathtub BT is sucked in. Further, a jet port 62 is provided on the side wall of the bathtub BT, and bath water containing relatively large bubbles is jetted from the jet port 62. The suction port 61 and the jet port 62 communicate with each other through a circulation pipe 63 piped outside the bathtub BT. A jet pump 64 is disposed in the middle of the circulation pipe 63, and the jet pump 64 is driven. By doing so, the bath water sucked from the suction port 61 is strongly jetted from the jet port 62. An air intake port 65 is provided in the flange F of the bathtub BT, and the air intake port 65 and the jet port 62 are communicated with each other. Further, oxygen-enriched air is supplied to the air intake port 65 from the oxygen enricher 1 described later via the supply path 3 and the second branch path 3b. The ejector port 62 is provided with an ejector portion, and the water taken in from the air intake port 65 is entrained in the bath water by ejecting the bath water from the jet port 62, and the bath water containing relatively large bubbles is ejected. It is like that.

  In the present invention, the oxygen enrichment device 1 is installed on the ceiling of the bathroom BR. The oxygen enrichment apparatus 1 is mainly composed of an oxygen enrichment film made of a flat film of an organic polymer and a vacuum pump, and takes air in the atmosphere with the vacuum pump and passes the air through the oxygen enrichment film. As a result, air enriched with oxygen can be obtained. When passing air through the oxygen-enriched membrane, oxygen and nitrogen decelerate, but oxygen passes at a rate approximately 2.5 times that of nitrogen. As a result, the air in the normal atmosphere was 78% nitrogen and 21% oxygen, but the oxygen-enriched film turned the air to 69% nitrogen and 30% oxygen, so-called oxygen having a relatively high oxygen concentration. Enriched air is obtained. The oxygen-enriched air obtained by the oxygen enricher 1 is supplied to the vicinity of the bathtub BT through the supply path 3. The supply path 3 is branched into branch paths (3a, 3b, 3c), which will be described later, and an electromagnetic valve 31 is provided at the branch, and the fine bubble generator 2, the oxygen enricher 1, the jet bath apparatus, and the like. 6 and the solenoid valve 31 are controlled by the control unit 5 installed on the ceiling. In addition, the branch part of the supply path 3 in which the electromagnetic valve 31 is provided is provided above the upper surface of the bathtub BT, and is installed on the ceiling in this embodiment. Further, the flange F of the bathtub BT is provided with operation switches SW 1 and SW 2 for operating the fine bubble generating device 2 and the jet bath device 6, and is electrically connected to the control unit 5.

  The supply path 3 is branched into a plurality of branch paths as described above, and is branched into three branch paths in the present embodiment. One of the branch paths (hereinafter referred to as the first branch path 3a) is connected to the microbubble generator 2, and the other branch path (hereinafter referred to as the second branch path 3b) is a jet. By connecting to the bus device 6, the discharge route 4 (41) does not pass through the fine bubble generating device 2, and the remaining one branch route (hereinafter referred to as the third branch route 3 c) is provided in the apron of the bathtub BT. By connecting to the bathroom supply port 43, the discharge path 4 (42) does not pass through the fine bubble generating device 2.

  In order to generate oxygen-enriched air as fine bubbles in the bath water, the solenoid valve 31 is switched to supply oxygen-enriched air to the first branch path 3a, and the oxygen-enriched device 1 is driven to make fine bubbles. When the circulation pump 25 of the generator 2 is driven, as shown in FIG. 2, bath water in the bathtub BT is sucked from the suction port 21 and supplied from the oxygen enricher 1 by passing through the ejector 24. The oxygen-enriched air supplied through the path 3 and the first branch path 3a is mixed in the bath water, and the bath water mixed with this oxygen-enriched air is sent to the dissolution tank 26 to enrich the bath water with oxygen. The bath water in which the oxygenated air is dissolved and the bath water in which the oxygen-enriched air is dissolved is discharged from the discharge port 22 under reduced pressure, whereby the bath water containing fine bubbles having a high oxygen concentration is discharged in a milky manner. Thereby, the bather in the bathtub BT is wrapped with fine bubbles to obtain a thermal effect, and the bather's skin breathing can be promoted because the bather is wrapped with fine bubbles of oxygen-enriched air. Thereby, the comfort level during bathing can be increased and the burden of cardiopulmonary function can be reduced. In addition, fatigue is restored (the action of lactic acid in the muscle being decomposed by oxygen is promoted) and the skin is activated. In particular, when the bubble diameter of the fine bubbles is reduced to make the residence time in the bath water 2 minutes or longer and the air of the fine bubbles is oxygen-enriched air, the dissolved oxygen concentration in the bath water increases. When the dissolved oxygen concentration in the bath water increases in this way, moisture penetration into the stratum corneum of the skin is promoted by a high amount of dissolved oxygen. In other words, the fine bubbles of oxygen-enriched air are dispersed widely in the bath water and stay for a long time, so that the oxygen partial pressure in the bath water increases, and osmotic pressure is generated in any part of the body in the bath water, and moisture penetration Promoted. Also, dissolved oxygen acts on the keratin natural moisturizing factor (NMF) to improve the water retention capacity. In addition, dissolved oxygen acts on intercellular lipids in the stratum corneum, improving the moisture retention capacity. By these, the moisturizing effect of the skin is improved, and the effect at the time of makeup is improved.

  Next, in order to eject oxygen-enriched air from the jet bath device 6, the solenoid valve 31 is switched to supply the oxygen-enriched air to the second branch path 3b, and the oxygen-enriched device 1 is driven. When the jet pump 64 of the jet bath device 6 is driven, as shown in FIG. 3, the bath water in the bath BT is sucked from the suction port 61, and the bath water passes through the jet port 62, whereby the oxygen enrichment device 1. The oxygen-enriched air supplied via the supply path 3 and the second branch path 3b is jetted into the bath water of the bathtub BT in a state of being mixed in the bath water. When the oxygen-enriched air is ejected into the bath water of the bathtub BT, the mixed oxygen-enriched air is released from the water surface into the air in the bathroom BR above, thereby reducing the burden on the cardiopulmonary function during lung respiration.

  Next, in order to eject oxygen-enriched air from the bathroom supply port 43, the solenoid valve 31 is switched to supply oxygen-enriched air to the third branch path 3c, and the oxygen-enriching device 1 is driven. The oxygen-enriched air supplied from the oxygen enrichment apparatus 1 via the supply path 3 and the third branch path 3c is directly released into the air in the bathroom BR from the bathroom supply port 43, and the cardiopulmonary function during lung respiration. The burden of is reduced.

  By adopting the configuration as described above, the oxygen-enriched air supplied from the oxygen enricher 1 is generated as fine bubbles from the fine bubble generator 2 via the first branch path 3a, so that during bathing The skin respiration can be promoted to improve the comfort of bathing and the burden of the worry function can be reduced. Further, the oxygen-enriched air is not discharged through the fine bubble generator 2 (second passage 4). By discharging into the bathroom BR via the discharge path 41 for discharging from the jet bath device 6 through the branch path 3b and the discharge path 42 from the bathroom supply port 43 via the third branch path 3c, The burden of cardiopulmonary function during pulmonary breathing can be reduced, and these can be switched as necessary.

  Further, the switching by the electromagnetic valve 31 may be switched between the case of supplying to the first branch path 3a and the third branch path 3c and the case of supplying to the second branch path 3b.

  For example, a device capable of generating 2 (liters / min) of oxygen-enriched air is used as the oxygen enrichment device 1, and a device capable of generating 0.5 (liters / min) of fine bubbles is used as the fine bubble generation device 2. In this case, only 0.5 (liter / min) of the oxygen-enriched air of 2 (liter / min) is used in the microbubble generator 2 and the remainder becomes surplus. At this time, as described above, the first When the solenoid valve 31 is switched so as to be supplied to the third branch path 3a and the third branch path 3c, 0.5 (liter / min) of oxygen-enriched air is used in the fine bubble generator 2 and the remaining 1. Oxygen-enriched air of 5 (liters / min) is directly discharged into the bathroom BR from the bathroom supply port 43, and oxygen-enriched air generated in the oxygen-enriching device 1 is used without waste. Maximize the capacity of the enrichment device 1 It is possible to limit use.
