You can heal your fatigue and relax.

On the other hand, jet water (hot water) a and high-pressure air b are jetted from each jet port 34 formed on the side surface of the body bath 3 to wash the body of the bather and stimulate the skin to relax. In that case, the pump 45 and the high-pressure air generator 46 of the gas-liquid injection device 4 are operated.

When, for example, an air compressor as the high-pressure air generator 46 is operated, air in the atmosphere is compressed to generate high-pressure air b, and the generated high-pressure air b is sent through the air supply pipe 46a toward the downstream side. Is
From the air inlet 42c to which the downstream end of the air supply pipe 46a is connected, the air pressure chamber 4 inside the gas-liquid injection nozzle 41
2b, and the air pressure chamber 42b becomes a high pressure state by the high pressure air b flowing in.

When, for example, a plunger pump as the pump 45 is operated, hot water on the water surface side in the body bath section 3 is discharged from the drain port 35a of the overflow 35, and the discharged hot water flows through the jet water circulation supply pipe 45a. It circulates and is pumped toward the downstream side, and the jet water circulation supply pipe 45
From the jet water inlet 44d to which the other end of a is connected, it flows into the inside of the fastening body 44 of the gas-liquid injection nozzle 41. The hot water that has flowed into the fastening body 44 from the jet water inlet 44d flows through the jet water flow passage 44c inside the fastening body 44 and is pressure-fed from the mounting port 44b to the jet water pressure chamber 43b of the jet water injection nozzle 43. .

The hot water pumped into the jet water pressure chamber 43b of the jet water jet nozzle 43 is pressurized there and is jetted forward from the small diameter jet water jet port 43a at the front end as high pressure jet water (hot water) a. To be done. The jet water jet nozzle 43 is an air pressure chamber 42b inside the exterior body 42.
And the air pressure chamber 42b is a high pressure air b.
Is full of.

Therefore, the high-pressure jet water (hot water) a jetted from the jet water jet port 43a has its side peripheral surface covered with the high-pressure air b. Then, from the gas-liquid injection port 42a of the gas-liquid injection nozzle 41 formed in front of the jet water injection port 43a, the high-pressure jet water (hot water) a has its side circumferential surface covered with the high-pressure air b in a cylindrical shape. In the state, it is jetted together with the high-pressure air b, and is jetted at high pressure into the hot water in the body bath 3 from the jet port 34 to which the gas-liquid jet nozzle 41 is attached.

Immediately after being jetted into the hot water in the body bath section 3 with high pressure, the jet water (hot water) a has its side peripheral surface cylindrically covered with the high pressure air b, so that The contact with the hot water is blocked by the high pressure air b, and the direct contact is relieved. In this way, the high-pressure air b alleviates the direct contact between the surrounding hot water, that is, the hot water in the body bath section 3 and the jet water (hot water) a. The resistance to the hot water becomes smaller.

As a result, the flight distance of the jet water (hot water) a in the hot water in the body bath section 3 can be extended,
That is, the jetting force can be prevented from being weakened by that amount, the strong jetting force can be maintained, and the jet water (hot water) a and the high-pressure air b due to the strong jetting force can be jetted onto the skin surface of the bather. The dirt can be washed away more effectively, and the bathing person's body washing effect can be enhanced.

Particularly, for a bather who cannot wash himself or herself, such as an elderly person or a sick person, the jet water (hot water) a and the high pressure air b with a strong jet force are more effective for removing dirt on the skin surface. Since it can be removed by washing, it is possible to reduce the work of the attendant washing the body of the bather.

In addition to this, the skin surface of the bather is stimulated by the jet water (hot water) a and the high-pressure air b with a strong jet force, so that fatigue can be healed and relaxed. Moreover, since the resistance between the surrounding hot water and the jet water (hot water) a can be reduced to suppress the occurrence of cavitation, it is possible to enjoy a quiet bath without the impact noise caused by cavitation.

The present invention is not limited to the embodiments of the present invention described above, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0053]

As is apparent from the above description, according to the sleeping hot tub of the present invention, it is possible to take a bath while lying on the back and wash the hair while lying on the back. This makes it easy for the elderly and the sick to take a bath, and the bubbles blown from the bottom of the bath make it easier to relax. In addition to this, the jet water immediately after being jetted into the body bath section at high pressure from a plurality of injection ports on the inner side surface of the body bath section has its side circumferential surface cylindrically covered with high pressure air. Therefore, the contact with the water in the body bath section is blocked by the high-pressure air, and the direct contact is relaxed, so that the resistance between the jet water and the water in the surrounding body bath section can be reduced. As a result, the jet force of the jet water is prevented from weakening, the jet force and high-pressure air can be jetted to the surface of the skin of the bather while maintaining a strong jet force. Therefore, the bathing person's body cleaning effect can be enhanced. Especially for bathers, such as the elderly and the sick, who cannot wash their own bodies, the water on the skin can be more effectively washed and removed by the jet water with high jetting force and high-pressure air. The work of washing the body of the bather by the person can be reduced. In addition, the surface of the bather's skin is stimulated by jet water and high-pressure air with a strong jetting force, so that fatigue can be healed and relaxed. Moreover, since the resistance between the surrounding water and the jet water can be reduced to suppress the occurrence of cavitation, it is possible to enjoy a very new and beneficial effect such as enjoying a quiet bath without the impact noise caused by cavitation. It plays.
