It can be used for re-bathing.

  Hereinafter, the best mode for carrying out the present invention will be described.

  FIG. 1 is a plan view showing an example of an embodiment of the present invention, in which a bathtub 1 and a washing place 10 are arranged in parallel in a bathroom. The bathtub 1 is provided with a fine bubble generator 2.

  As shown in FIG. 2, the fine bubble generating device 2 is formed by providing an aeration unit 16, a pressure pump 17, and a gas-liquid dissolution tank 5 along a flowing direction of hot water in a hot water flow path 15. A spout 9 is provided at the downstream end of the water channel 15. In addition, a switching valve 8 is provided at the upstream end of the hot water flow channel 15, and one end of each of the hot water supply channel 6 and the mixed water supply channel 7 is connected to the hot water flow channel 15 via the switching valve 8. is there. A suction port 4 is provided at the other end of the hot water supply path 6. A mixing plug 18 is connected to the other end of the mixed water supply path 7, and a water supply path 19 for supplying primary water from a water pipe or the like to the mixing plug 18 and a hot water supply path for supplying primary hot water from a water heater or the like. 20 is connected.

  The suction port 4 and the jet port 9 are respectively provided on the inner wall surface of the bathtub 1 as shown in FIG. Further, the mixing plug 18 and the mixed water supply path 7 are arranged below the counter 21 provided in the washing place 10, and the fine bubble generating device 2 and the hot water supply path 6 are below the flange 22 formed at the upper end of the bathtub 1. Of course, it is not limited to this.

  Moreover, the overflow part 3 is provided in the position of one edge part of the side facing the washing place 10 among the flanges 22 provided in the perimeter of the upper end of the bathtub 1. For example, as shown in FIG. 3, the overflow portion 3 is formed in a U-shaped groove shape whose upper surface is open, and at the position immediately below the overflow portion 3, a drain outlet is provided at the end of the washing place 10 on the bathtub 1 side. 11 is formed. The overflow portion 3 may be formed in a groove shape as described above, or may be formed so as to be inclined so that a part of the flange 22 is lower than the other part.

  In the fine bubble generating device 2 described above, when bathing in the bathtub 1, the switching of the switching valve 8 blocks the communication of the mixed water supply path 7 with respect to the hot water flow path 15 and supplies hot water. The road 6 is made to communicate. When the pressurizing pump 17 is activated, hot water in the bathtub 1 is sucked into the hot water supply path 6 from the suction port 4 by the suction force, and flows from the hot water supply path 6 through the switching valve 8 through the hot water flow path 15 to the air. When passing through the mixing unit 16, air is sucked and mixed with hot water. The air mixing part 16 is formed by an ejector or the like, and air is sucked and mixed by using a negative pressure when hot water flows through the air mixing part 16. The hot water mixed with air in this way is pumped to the gas-liquid dissolution tank 5 by the pressurizing pump 17. By the pressure pump 17, hot water mixed with air is pressurized in the gas-liquid dissolution tank 5, and air-dissolved water in which air is dissolved at a high concentration in the hot water is generated. Air-dissolved water generated in the gas-liquid dissolution tank 5 is spouted from the spout 9 into the hot water of the bathtub 1. At this time, the air-dissolved water in which the air is dissolved at a high concentration is pressurized to a high pressure in the gas-liquid dissolution tank 5, and when the air-dissolved water is ejected from the spout 9 into the hot water of the bathtub 1. Since the pressure is suddenly released, the dissolved air is precipitated as fine bubbles (microbubbles) having a diameter of 10 to 20 μm and discharged into the hot water of the bathtub 1.

  Such fine bubbles having a particle diameter of 10 to 20 μm have extremely small bubble diameters and are excellent in dispersibility and buoyancy. Therefore, it takes time to rise to the surface of the water, and every corner of the hot water in the bathtub 1 It is dispersed to become an opaque milky white cloudy water like a milk bath, and can be bathed with visual enjoyment, and a warm bath effect can be obtained with fine bubbles. In addition, fine bubbles are a function that envelops dirt on the surface of the body of a person taking a bath and an action that ruptures fine bubbles to remove dirt from the body. The effect can also be expected.

  While bathing in this way, hot water in the bathtub 1 is circulated in the order of the suction port 4, the hot water supply path 6, the fine bubble generator 2, and the spout 9, and the hot water in the bathtub 1 is circulated in the fine bubble generator. It is made to discharge in the bathtub 1 in the state which was supplied to 2 and the air was dissolved.

  Next, the washing | cleaning in the bathtub 1 after finishing bathing is demonstrated. In the same manner as described above, the cleaning is performed by operating the pressurizing pump 17 in a state where the hot water flow path 15 is disconnected from the mixed water supply path 7 and the hot water supply path 6 is connected. When the pressurizing pump 17 is operated in this way, the remaining hot water after bathing is sucked into the hot water supply path 6 from the suction port 4. In the same manner as described above, the hot water is supplied from the hot water supply path 6 to the air mixing section 16 through the hot water flow path 15, and air is mixed with the hot water, and is further pumped to the gas / liquid dissolution tank 5 by the pressure pump 17. Air dissolved water in which air is dissolved at a high concentration is generated. Air-dissolved water generated in the gas-liquid dissolution tank 5 is jetted into the remaining hot water of the bathtub 1 from the jet outlet 9, and fine bubbles are generated in the remaining hot water. When fine bubbles are generated in the remaining hot water in this way, dirt such as sebum, hair, soap scum and the like floating in the remaining hot water is wrapped in the fine bubbles, and the dirt rises on the water surface together with the fine bubbles. Moreover, the dirt adhering to the inner wall surface of the bathtub 1 below the remaining hot water surface is also encased in fine bubbles, and is peeled off from the wall surface and floats on the water surface by the bursting action of the fine bubbles.

  In this way, the remaining hot water and dirt on the inner wall surface of the bathtub 1 can be floated on the surface of the water by the action of the fine bubbles generated by the fine bubble generating device 2, and washing can be performed using a detergent. There is no need to carry out, and the running cost of using a detergent becomes unnecessary. Moreover, since it can wash | clean using the microbubble generator 2, it becomes unnecessary to provide the nozzle for a bathtub washing in a bathtub, or the system for discharging washing water and rinsing water. It is not complicated or expensive.

  After the remaining hot water and the stain on the inner wall surface of the bathtub 1 are floated on the surface of the remaining hot water with fine bubbles as described above, the switching valve 8 is switched to block the hot water supply path 15 from communicating with the hot water supply path 6. In addition, the mixed water supply path 6 is communicated. When the pressurizing pump 17 is operated, primary water is supplied to the mixing tap 18 from the water supply channel 19 and primary hot water is supplied from the hot water supply channel 20, and hot water is mixed at the mixing plug 18 to adjust the temperature to be suitable for bathing. The hot / cold mixed water thus supplied is supplied to the hot / cold water flow path 15 through the mixed water supply path 7. In the same manner as above, this hot / water mixed water is sent to the air mixing section 16 where air is mixed, and the hot / water mixed water mixed with air is further pumped to the gas / liquid dissolution tank 5 by the pressurizing pump 17, Air-dissolved water in which air is dissolved at a high concentration is generated in the dissolution tank 5. This air-dissolved water, in which air is dissolved in the hot-water mixed water, is jetted into the remaining hot water of the bathtub 1 from the jet outlet 9.

  In this way, air dissolved water in which hot water and water are mixed is discharged to the remaining hot water in the bathtub 1, and the remaining hot water is washed with the generated fine bubbles, and the hot water mixed water is supplied in the bathtub 1. The water level rises. When the water level rises in this way, the dirt adhering to the inner wall surface of the bathtub 1 above the remaining hot water surface is below the water surface, so that the dirt can be lifted off from the wall surface with fine bubbles, The inner wall surface of the bathtub 1 above the surface of the remaining hot water can be washed.

  When the water level rises and the water surface reaches the overflow portion 3, hot water near the water surface overflows from the overflow portion 3 and is discharged. Due to the overflow of hot water near the water surface, the dirt floating on the water surface is discharged together with the hot water, and the dirt can be removed from the hot water in the bathtub 1. In this way, when the hot water containing dirt is overflowed and discharged from the overflow part 3, the drain port 11 of the washing place 10 is provided at a position immediately below the overflow part 3. It flows in and is discharged from the bathroom, so that hot water containing dirt does not spread to the washing place 10 and contaminate the washing place 10.

  The hot and cold water in the bathtub 1 after washing as described above is composed of the remaining hot water from which dirt has been removed and fresh hot / cold water mixed with hot water. Therefore, for those who continue to bathe, they can be immersed in clean hot water like a bath.

It is a top view which shows an example of embodiment of this invention. It is the schematic which shows a fine bubble generator same as the above, and its periphery mechanism. It is a perspective view of an example of a bathroom.
