Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a device used in a bathtub, in which bath water is repeatedly and intermittently sprayed from above the body to the bottom or from the bottom to the top, This invention relates to a bath water spouting device that is effective in treating body stiffness and maintaining and promoting health through water jet massage.

[Conventional technology]

Japanese Patent Publication No. 15697/1984 is known as a device that uses a pump to forcibly circulate hot water in a bathtub and also installs a device that sprays hot water into the bathtub.

[Problem that the invention seeks to solve]

The above-mentioned known method sprays hot water onto the body from a single spray nozzle fixed in the bathtub, so the hot water only hits certain parts of the body, so the pine surge effect to relieve stiffness throughout the body. The problem was that we couldn't expect much from them.

[Means for solving problems]

The present invention provides for a bathtub to be sprayed at regular intervals in the vertical direction on one side wall of the bathtub so that intermittent spray is repeatedly applied to the body in the bathtub from above to below (or from below to above). A fluid inlet and a plurality of fluid inlets are provided such that a plurality of jet nozzles are provided to direct the water to the fluid inlet and the plurality of fluid A pipe connecting the fluid outlet and the plurality of injection nozzles of a fluid distribution valve, the fluid distribution valve having a plurality of communication passages connecting the outlet and a rotary valve body having a fluid flow passage that intermittently opens and closes the communication passage. They are connected to each other via.

[Effect]

The bath water sucked by the pump enters the fluid inlet chamber 15 from the fluid inlet 9 through the conduit, and the fluid outlet path of the rotary valve body 16 which is rotated by the deceleration motor 17 within the fluid inlet chamber 15. 8, 8, and a communication path 1 that intermittently communicates with the fluid outflow paths 8, 8.
9, 20, 21, 22, and from the upper injection nozzle 2 to the lower injection nozzles 3, 5, 4 sequentially via the connecting pipe 6, or from the lower injection nozzle 4 to the upper injection nozzles 5, 3, 2 sequentially. Intermittent water discharge into the bathtub is repeated in sequence.

〔Example〕

To explain the drawings showing an embodiment of the present invention, a pair of injection nozzles 2, 2 are provided on one side wall of a bathtub 1 at a constant interval in the vertical direction for spraying bath water to a position corresponding to the shoulder; A pair of injection nozzles 3, 3 for spraying at a position corresponding to the shoulder flaps, and a pair of injection nozzles 4, 4 for spraying at a position corresponding to the waist.
and an injection nozzle 5 for ejecting to a position corresponding to the back of the stomach in the central part between the injection nozzles 3 and 4. These injection nozzles 2 to 5 each have a fluid distribution valve 7 having a plurality of fluid outflow passages 8, 8 that are intermittently opened and closed via connection pipes 6...
is connected to. One fluid inlet 9 and a pair of fluid outlets 10 are provided on the outer peripheral surface of the valve casing 14.
11 and 12 are provided radially, and one fluid outlet 13 is further bored in the front surface, and a pair of fluid outlet channels 8 and 8 are laterally penetrated into a fluid inlet chamber 15 communicating with the fluid inlet 9. A rotary valve body 16 is fixed to an output shaft 18 of a deceleration motor 17 and is rotatably installed, and the fluid outlet ports 10 to 13 and the fluid inlet chamber 15 are arranged on the circular locus of rotation of the fluid outlet channels 8, 8. Communication passages 19 to 22 are provided to connect the two, and a fluid distribution valve in which the communication passages 19 to 22 open and close intermittently is constructed. The fluid inlet 9 and the suction port 23 are connected by a conduit 24 via a pump 25 for circulating bath water, so that the bath water sucked from the suction port 23 by the pump 25 flows through the conduit 24. The fluid is supplied to the fluid inlet 9 through the fluid inlet 9. The fluid entering the fluid inlet chamber 15 from the fluid inlet 9 passes through the fluid outlet passages 8, 8 of the rotary valve body 16 rotated by the deceleration motor 17, and passes through the communication passage 19.
- 22, the fluid is intermittently injected into the bathtub 1 from the injection nozzles 2-5 via the fluid outlets 10-13.

In this embodiment, the injection nozzles 3 and 4 are as follows:
An air intake port 26 is provided at the inlet portion of the nozzle, and the connecting pipe 6 is used as a double pipe to take in air.
The injection nozzles 2 and 4 are configured to flow out into the bathtub as air bubbles, and the injection nozzle 5 is configured to have a turbulent flow chamber 27 having a recess 28 in a part of the nozzle opening so that cavitation phenomenon occurs. Then, a nozzle capable of generating ultrasonic waves is used, which generates ultrasonic waves by the impact sound pressure when the bubbles generated by the cavitation collapse, and the injection nozzle 2
Although the nozzles are used to eject water vigorously, the combination of the injection nozzles 2 to 5 is not limited to this, and one type or two or more types of injection nozzles may be used in an appropriate combination.

It goes without saying that a generally known injection nozzle can be used as the injection nozzle. Furthermore, the injection nozzles may be freely arranged in one or two rows.

〔effect〕

According to the present invention, a plurality of injection nozzles are provided on one side wall of the bathtub and are directed into the bathtub at regular intervals in the vertical direction, and the plurality of injection nozzles are
Since each of the fluid distribution valves 7 is connected to the plurality of outflow ports of the fluid distribution valve 7, which has a plurality of fluid outflow ports that open and close intermittently, the rotary valve body having the fluid flow path intermittently opens and closes the communication path by the rotation of the deceleration motor. Since the process of opening and closing is repeated intermittently from the upper injection nozzle to the lower injection nozzle or from the lower injection nozzle to the upper injection nozzle, the shoulders, shoulder blades, back of the stomach, lower back, etc. of the body in the bathtub are Since the bath water is intermittently sprayed repeatedly in sequence, the water jets from these spray nozzles automatically and continuously massage the body, as if by a chair-type pine massage machine.
It has a particularly excellent pine surge treatment effect on the shoulders, shoulder blades, back of the stomach, lower back, etc., and is excellent for maintaining and improving health.
