Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a device used in a bathtub, in which bath water is intermittently and repeatedly sprayed from above the body to the bottom or from the bottom to the top, This relates to a bath water spouting device that is effective in treating body stiffness and maintaining and improving health through water flow pine surge. Japanese Patent Publication No. 61-15697 is known as a device equipped with a spraying device.

[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. ◎ [Means for solving the problem] The present invention sequentially and intermittently moves the body in the bathtub from the top to the bottom (or from the bottom to the top). A plurality of spray nozzles are provided on one side wall of the bathtub and are directed into the bathtub at regular intervals in the vertical direction so that water can be sprayed repeatedly. 1) a plurality of communicating passages connecting a fluid inlet and a plurality of fluid outlets, and a fluid flow passage that intermittently opens and closes the communicating passages. The fluid outlet of the fluid distribution valve and the plurality of injection nozzles are respectively connected via a connecting pipe.

[Effect]

The bath water sucked by the pump enters the fluid inlet chamber 15 from the fluid inlet 9 through the conduit, and flows through the fluid outlet path 8.8 of the rotary valve body 16, which is rotated by the deceleration motor 17 within the fluid inlet chamber 15. through a communication path 19°20.21.22 that communicates intermittently with the fluid outlet path 8.8, and sequentially from the upper injection nozzle 2 to the lower injection nozzle 8°5.4 via a connecting vibro, or Intermittent water is repeatedly sprayed from the lower spray nozzle 4 through the upper spray nozzles 5, 8.2 into the bathtub.

〔Example〕

To explain the drawings showing one embodiment of the present invention, a pair of spray nozzles 2.2 are provided on one side wall of the bathtub 1 at a constant interval in the vertical direction for spraying bath water to a position corresponding to the shoulders; A pair of injection nozzles 8.8 for injection to a position corresponding to the shoulder flaps, a pair of injection nozzles 4.4 for injection to a position corresponding to the waist, and a central part between the injection nozzles 8.4 corresponding to the back of the stomach. A spray nozzle 5 is installed to spray the water at the desired position. These injection nozzles 2 to 5 are each connected to a fluid distribution valve 7 having a plurality of fluid outflow passages 8.8 which are opened and closed intermittently through connecting vibros. One fluid inlet 9 and a pair of fluid outlets 10°11.12 are provided radially on the outer peripheral surface of the valve casing 14,
Furthermore, one fluid outlet 13 is bored in the front surface, and a pair of fluid outlet channels 8 are provided in the fluid inlet chamber 15 communicating with the fluid inlet 9.
．． A rotary valve body 16 having 8 laterally penetrated therethrough is fixed to the output shaft 18 of the deceleration motor 17 and is rotatably installed, and the fluid outlet ports 10 to 1 are arranged on the circular locus of rotation of the fluid outlet passage 8.8.
8 and the fluid inlet chamber 15 are provided to form a fluid distribution valve in which the communication paths 19 to 22 open and close intermittently. The fluid inlet 9 and the suction port 28 are connected by a conduit 24 via a pump 25 for circulating bath water. supplied to inlet 9 @ and
The fluid that enters the fluid inlet chamber 15 from the fluid inlet 9 passes through the fluid outlet passage 8.8 of the rotary valve body 16 rotated by the deceleration motor 17, and flows from the communication passages 19 to 22 to the fluid outlet 10.
18, and is intermittently injected into the bathtub 1 from the injection nozzles 2 to 5.

In this embodiment, the injection nozzles 8 and 4 have an air intake port 26 at the inlet part of the nozzle, and the connected vibro is used as a double pipe to take in air, and from the injection nozzles 2 and 4 it flows out as air bubbles into the bathtub. In addition, the injection nozzle 5 is configured such that a turbulent flow chamber 27 having a recess 28 is provided in a part of the nozzle orifice to cause a cavity air phenomenon to occur, and the air bubbles generated by the air bubbles are generated by the air bubbles. A nozzle capable of generating ultrasonic waves is used, which generates ultrasonic waves by the impact sound pressure when the material is crushed, and the injection nozzle 2 is a nozzle that ejects water vigorously, but the combination of injection nozzles 2 to 5 is not limited to this. Rather than using a single injection nozzle, one type or two or more types of injection nozzles are used in appropriate combination.

Furthermore, it goes without saying that the injection nozzles may be those that are already generally known. Furthermore, the injection nozzles may be freely arranged in one or two rows. [Effect] The present invention has the following effects. 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. Since the rotary valve body having a fluid flow path intermittently opens and closes the communication path by the rotation of the deceleration motor to flow from the upper injection nozzle to the lower injection nozzle or from the lower injection nozzle to the lower injection nozzle. Since the spray nozzle is sequentially opened and closed from one spray nozzle to the upper spray nozzle, bath water is sprayed intermittently onto the shoulders, shoulder bones, back of the stomach, lower back, etc. of the body in the bathtub. It exhibits a much superior pine surge treatment effect compared to other devices, and is excellent for maintaining and improving health.
