/15 is a forced JJI water valve located on the lower left side of the rear face of the bubble vibrating bathtub 11 as shown in FIG. Reference numerals 46 and 717 designate two nozzle control valves for lower limb and upper limb baths, which are also installed on the right side of the forced drainage valve 45, respectively.
5. The purifying and foaming power from 25 can be adjusted.

-7- Next, for the lower limb and upper limb baths! +1! The structure of the bubblers 15 and 25 will be explained. In this embodiment, the foamers 15 and 15 for the lower limb bath and the -1-limb bath are of the same WJ construction, so the foamer 15 for the lower limb bath will be explained with reference to FIGS. 7 to 9.

Reference numeral 51 denotes a nozzle body having a threaded portion 51a formed on the inner circumferential surface of the tip side opening, and a space 52 is provided at the inner bottom side of the opening. Reference numeral 53 denotes a cylindrical joint 1 provided on the outside of the upper part of the base end of the nozzle body 51, which is connected to an air supply pipe (not shown) through which outside air flows in from one end via the air inflow adjustment valve 38. There is. 54 is the join 1
-53 and one side of the space 52, and as shown in FIG. 51, it is formed in the shape of a sea urchin flowing obliquely toward the central axis of the sea urchin.

Reference numeral 55 is a cover provided outside the lower part of the base end of the nozzle body 51.
8=A cylindrical joint, one end of which is connected to a hot water pipe 65 connected to the ejection side of a pump motor 61, which will be described later. Therefore, the hot water sucked from the suction II 16 flows into the joint 55 via the pump motor 61 and the hot water pipe 65. 56 is a hot water spout which is removably screwed into the center right side of the space 52. It is a nozzle, and its ejection hole 56a communicates with the joint 55 via an inlet/outlet passage 55a.

57 is a foaming nozzle whose threaded portion 57a is removably screwed onto the threaded portion 51a of the nozzle body 51, and the flange 57b formed on the outer periphery of the tip and the nozzle body 51 are connected to the lower leg through the front and back gaskets 58. The bathtub 12 is fixedly installed on the wall. Reference numeral 57c denotes an ejection hole provided through the medium heat section of the foaming nozzle 57, which is coaxial with the ejection hole 56a of the hot water injection nozzle 56, and the right end opening is widened in a trumpet shape.

Therefore, when the water is ejected forcefully from the IVi recording ejection nozzle 56 to the ejection hole 57C of the foam nozzle 57,
-〇 - The space 52 of the nozzle body 51 becomes under negative pressure, and when outside air flows forcefully into the space 52 from the air supply pipe, it is simultaneously sucked into the ejection hole 57G of the foaming nozzle 57,
Foaming llY vibrates within the same nozzle 57C. The foam flY is then ejected into the lower limb bathtub 12 while emitting ultrasonic waves. Moreover, in this case, the outside air sucked into the spout hole 57C of the foaming nozzle 57 flows in a straight line to the spout hole 57C.
Since the air inflow path 54 is formed obliquely, the outside air drawn in onto the central axis of
It is sucked in and the foaming efficiency is very high.

Furthermore, by adjusting the air inflow regulating valve 38, the amount of ultrasonic foaming can be appropriately selected.

Next, the piping structure of the bubble vibrating bathtub 11 constructed as described in item 1 will be explained with reference to FIG.

61 is a pump motor composed of a cascade pump 62 and an electric motor 63, and one end is connected to a suction pipe 6 on the suction side.
It is connected to the suction port 16 via a tube 4 = 10-, and the other outlet side is connected to foamers 15 and 25 for lower limb and upper limb baths, respectively, via a hot water supply pipe 65 branched in the middle. Therefore, the water sucked in from the suction port 16 is ejected from the lower limb and upper limb bath foamers 15 and 25 via the suction pipe 61, the cascade pump 62, and the water supply pipe 65. In this case, each of the foamers 15.
The ejection force of the lagoon from 25 can be selected as appropriate, and it is also possible to send d3S to only one of them. In addition, the pressure regulating valve 39 is connected between the suction pipe 64 and the hot water pipe 65, and feeds back the J5m flowing in the hot water pipe 65 to the suction pipe 64.
- The spouting horn of the foot bath foamer 15.25 can be adjusted.

60 is installed above the suction pipe 6/I and the upper limb bathtub 13 (
A small amount of air is sent to the suction side of the cascade pump 62 through the suction pipe 11 connected between the suction fittings 23. Therefore, the cascade pump 62
The load applied to the impeller changes depending on the air bubbles mixed in, and the inherent vibration of the impeller changes due to this change in load, which eliminates the resonance effects of other members and prevents resonant metallic sounds.

Reference numeral 67 denotes a forced water pipe connected to the lagoon pipe 671, and when the forced water valve 45 is opened, hot water is forcibly discharged from the cascade pump 62. Therefore, the lagoon in the lower limb bathtub 12 can be drained and covered in a short time. 68 is a natural discharge pipe connected to the discharge port 19.

Next, the operation of the bubble vibrating bathtub 11 configured as described above will be explained.

Now, water supply and temperature supply valve 40. After listening to /11 and supplying hot water into the bubble vibrating bathtub 11, the main switch 37 is turned on. Next, turn on the heater switch 36 and adjust the heater control knobs 3-12-5 to set the lagoon control I setting. Therefore, the heater 18a on the outer periphery of the suction logo 6 is connected to the temperature detection sensor iJ--
Heating operation based on the humidity detection of 18 is possible.

After setting the control settings for the lake, when the timer 30 is set to 1 to 1 at a predetermined time, the pump mokuro 1 is operated for the 1 to 1 hour of the timer 30, and the foamer 15 for lower and upper limb baths is activated.
A group of ultrasonic bubbles is ejected from 25.

When the user enters the bubble vibrating bathtub 11 while sitting on the upper limb bathtub 13, the ultrasonic bubbles iY from the upper limb bathing foamer 25 will be applied to the affected part of the lower back, and the ultrasonic bubbles from the lower limb bathing foamer 15 will be used to treat the affected part of the legs. Each affected area can be treated with ultrasonic bathing.

In addition, nozzle controller for lower limb and upper limb bath [・Roll valve/1
By adjusting 6.47, the ejection force of the ultrasonic foaming group can be appropriately selected, and the ultrasonic foaming group can also be ejected from only one of them. Moreover, since the air inflow path 54 is formed obliquely, the outside air is efficiently sucked into the ejection hole 57C of the foaming nozzle 57, resulting in very high foaming efficiency.

In particular, in the present invention, the spout hole 56a of the hot water spout nozzle 56 is formed on the inner bottom surface of the opening of the nozzle body 51.
A spout nozzle 56 on the same side is removably screwed so as to communicate with a hot water temperature inlet passage 55a provided through the hot water, and a foaming nozzle 57 having a spout hole 570 on the same axis as this spout hole 56a is connected to the hot water spout. An air inflow path 54 is removably screwed onto the opening of the nozzle body 51 so as to be located in front of the nozzle 56 and sucks and inflows air between the hot water spouting nozzle 56 and the foaming nozzle 57. It is characterized by being formed in Therefore, by removing the foaming nozzle 57 and the hot water spouting nozzle 56, there is an effect that both the nozzles 57, 56 and the inside of the nozzle body 51 can be easily cleaned. This is particularly effective when both nozzles 57 and 56 are clogged with dust.
