Description

[Detailed description of the invention] This invention sprays an ultrasonic foam group into a bathtub,
This invention relates to a bubble vibrating bathtub for treating radial pain, rheumatism, muscle pain, etc.

Conventionally, this type of bathtub uses a cascade pump to squirt the hot water in the bathtub from a foaming nozzle back into the bathtub, and at the same time sucks air using negative pressure from one side of the foaming nozzle to create ultrasonic foaming. The group was squirting out together with the hot water. However, during operation of the cascade pump, the impeller of the cascade pump generates a unique vibration that induces a resonance phenomenon due to the load of hot water being sent to the nozzle, thereby generating a metallic sound. Therefore, the patient was experiencing great discomfort.

The purpose of this invention is to solve the above-mentioned defects by creating a bubble vibrating bathtub that uses bubbles to change the load applied to the impeller of a cascade pump, eliminates the metallic sound caused by the resonance phenomenon of the impeller, and does not cause discomfort to patients. is to provide.

5 and set the hot water control temperature. Therefore, the heater 18a on the outer periphery of the suction port 16 can perform a heating operation based on the temperature detected by the temperature detection sensor 18. After setting the control temperature of the hot water, when the timer 30 is set to a predetermined time, the pump motor 61 is operated for the time set by the timer 30, and ultrasonic foam is ejected from the lower limb and upper limb bath foaming nozzles 15 and 25. .

Then, if you sit on the upper and lower extremity chair 77 and put your feet or arms into the lower extremity or upper extremity bathtubs 12 and 13, the ultrasonic foam group from the lower extremity bathing foaming nozzle 15 will treat the affected part of your leg with the upper extremity bathing foaming nozzle. The affected part of the arm can be treated with ultrasonic hot bath using the ultrasonic foaming group from 25. If you sit in the bubble vibrating bathtub 11 while sitting on the upper limb bathtub 13, the ultrasonic foam from the upper limb bathing foam nozzle 25 will treat the affected area of your lower back.
The affected parts of the legs can be treated with ultrasonic hot bathing using the ultrasonic foaming group from the foaming nozzle 15 for lower limb bathing. Further, by using the horizontal bar 75, a patient with a disability can get in and out of the bathtub 11 by holding on to the horizontal bar 75.

Further, by adjusting the lower limb and upper limb bath nozzle control valves 46 and 47, the ejection force of the ultrasonic foam group can be appropriately selected, and the ultrasonic foam group can also be ejected to only one of them.

Furthermore, the cascade pump 62 that spouts out the ultrasonic foam group sucks air from the vent hole 23a of the air suction fitting 23 through the suction pipe 66 along with the hot water from the suction port 16. The load on the car changes depending on these bubbles. Therefore, since the natural vibration of the impeller changes due to this change in load, resonance with other installed members is eliminated, and resonant metallic noise can be prevented.

Note that the present invention is not limited to the above-mentioned embodiment, and as shown in FIGS. 15 and 16, the upper limb bathtub 13 is eliminated and a seat 81 is provided in its place, so that only the lower limb bathtub 12 is provided. Bubble vibrating bathtub 11
