Description

[Detailed Description of the Invention] This invention relates to an improvement of a jet bath device that generates jets in hot water in a bathtub to provide a jet bath.

Jet baths can be divided into bubble jet baths, in which air bubbles are mixed in the hot water jet jetted into the bathtub from a nozzle, and whirlpool jet baths, in which hot water is jetted out in a vortex state without air bubbles mixed in. Jet baths have a strange feeling, and whirlpool jet baths are more suitable for changing your mood and relieving stress.

Therefore, this invention provides a jet bath device that allows the bather to selectively perform both the bubble jet bath and the whirlpool jet bath, thereby fully utilizing the advantages of both the bubble jet bath and the whirlpool jet bath. The purpose is to

Next, this invention will be explained in detail with reference to illustrated embodiments.

In the illustrated embodiment, the jet device 1 of the jet bath device is attached to the side wall 21 of the bathtub 2 .
The jet device 1 is a cap in which a plurality of air/hot water discharge ports 41 are arranged concentrically and in a planetary manner with respect to the hot water discharge port 31 along the outer periphery of a hot water nozzle 3 through which a hot water discharge port 31 is provided in the axial direction. 4 are coaxially fitted together, and the hot water outlet 31 and the air/hot water outlet 41 are connected to the flexible nozzle 5 facing the inside of the bathtub 2.The attachment to the side wall 21 of the bathtub 2 is , the washer 12 is screwed into the casing 11, and the gaskets 13, 13 are fitted in a watertight manner. 5 is designed to be able to freely change direction in either the up/down or left/right directions. The cap 4 is pressed toward the universal nozzle 5 by a coil spring 43, so that the seating surface 42 comes into contact with the universal nozzle 5. Further, the flexible nozzle 5 is held watertight by an O-ring 51.

A hot water inlet 32 and an air/hot water inlet 44 (both have approximately the same diameter) are provided on the upstream side of the hot water nozzle 3 and the cap 4, respectively. The downstream ends of the first circulation pipe 6 and the second circulation pipe 7, through which hot water circulates, are connected.

The upstream ends of the first circulation pipe 6 and the second circulation pipe 7 are connected to the lower side of the bathtub 2, and the first circulation pipe 6
A circulation pump P is disposed in the path, and the circulation pump P forcibly circulates hot water in the bathtub through the first circulation pipe 6, and the circulation is controlled by an operating valve 61 such as a manual valve.

Further, an air supply pipe 8 is connected to the second circulation pipe 7 at a position higher than the highest water level l of the bathtub 2, and a solenoid valve or other operating valve 71 is provided downstream from this connection position. It is being

The upstream end of the air supply pipe 8 is an air intake port 81, and an operating valve 82 such as a solenoid valve and a check valve 8 are provided in the path.

In the illustrated embodiment, in order to mix the chemical liquid or cold water into the jet stream, the chemical liquid or cold water mixing pipe 9 is connected to the downstream side of the second circulation pipe 7 (downstream of the operation valve 71), and its upstream end is chemical liquid (cold water) tank 9
1, and opening/closing of the chemical liquid or cold water mixed pipe line 9 is performed by an operating valve 92 such as a solenoid valve.

In addition, in the second embodiment shown in FIGS. 3 and 4, a nozzle body 4 has a plurality of air/hot water discharge ports 41A arranged in a planetary manner and passed through the hot water discharge port 31.
B is fitted, and this nozzle body 4B is connected to the cap 4A.
It has a structure that is attached to the

Next, to explain the action, the circulation pump P
When the hot water in the bathtub 2 is taken into the first circulation pipe 6 and forced to circulate (the operating valve 61 is opened), the hot water passes through the hot water inlet 32 and enters the hot water nozzle 3.
The hot water is fed under pressure and is ejected from the hot water outlet 31 toward the adjustable nozzle 5. This jetting generates a negative pressure in the hot water nozzle 3, and this negative pressure starts the circulation in the second circulation pipe 7. However, when performing a bubble jet bath, the operation of the second circulation pipe 7 is The operation valve 82 of the air supply pipe 8 may be opened at the same time as the valve 71 is opened, so that the air sucked from the air intake port 81 is transferred from the air supply pipe 8 to the second circulation pipe 7.
from the air/hot water inlet 44 to the air/hot water outlet 41 or 41A of the cap 4 or the nozzle body 4B, and merges with the hot water jet jetted out from the hot water outlet 31 to form a bubble jet to the free nozzle 5. It is possible to perform a bubble jet bath by squirting into the hot water in the bathtub, and when performing a whirlpool jet bath,
If the operation valve 82 of the air supply pipe 8 is closed, the flow of air into the second circulation pipe 7 is stopped, and the second circulation pipe 7 is filled with only hot water, similar to the first circulation pipe 6. Only hot water flows out from the air/warm water discharge port 41 or 41A, merges with the jet flow of the first circulation pipe, and jets out from the adjustable nozzle 5 to provide a vortex jet bath.

In addition, by intermittently opening and closing the operating valve 71 of the second circulation pipe 7, the force of the jet can be changed in two stages, in both the bubble jet bath and the vortex jet bath, thereby creating a type of You can get the pine surge effect.

Furthermore, the operation valve 9 of the chemical liquid or cold water mixed pipe line 9
2 is opened and the operation valve 71 of the second circulation pipe 7 is closed, the chemical liquid or cold water is supplied to the second circulation pipe 7, and it becomes possible to mix the chemical liquid or cold water into the jet of the vortex jet bath. The effect of the whirlpool bath can be enhanced.

As described above, according to this invention, air or hot water is supplied from the second circulation pipe in conjunction with the jet of hot water forcedly circulated by the first circulation pipe, and either a bubble jet or a vortex jet is generated. The jet can be selectively emitted according to the bather's choice, allowing the bather to select either a bubble jet bath or a whirlpool jet bath as appropriate, allowing the bather to select a jet jet that suits their physical condition and preferences. It is possible to take a bath.
