Abstract

PROBLEM TO BE SOLVED: To provide larger massage effect and relaxation effect by arranging three or more jetting ports of hot water and air on the same plane in a bathtub, and generating a vortex form convection current in hot water in the bathtub by jetting hot water in which air bubbles are mixed from respective jetting ports in a proper order. SOLUTION: On the same inner peripheral surface in a bathtub 1, a large number of concentric jetting ports 2A to 2D are arranged, and respective solenoid valves 4A to 4D are arranged on respective branching pipes 3A to 3D which connect the jetting ports 2A to 2D. Respective jetting ports 2A to 2D are turnably installed, and the jetting directions are made changeable. Therefore, when respective jetting ports 2A to 2D are faced, e.g. to the outside, a convection current such as a gradually expanded tornado can be formed, and when faced to the inside, a convection current such as a gradually narrowed tornado can be formed. Also, when respective jetting ports 2A to 2D are automatically turned and inclined to the inside, a convection current of a vortex form, not a tornado form, can be formed. By this constitution, a dynamic convection current can be generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet bath for injecting hot and cold water mixed with air bubbles to provide a soothing heat effect, a massage effect or a relaxing effect to a bather's body. It is about a tornado whirlpool.

[0002]

2. Description of the Related Art In recent years, hot and cold water mixed with air bubbles has been jetted into a bath tub from a jet nozzle provided facing the bath tub, and the hot and cold water in the bath tub has been fluidized. Whirlpools have been developed and used which provide a warming, massage or relaxing effect.

This whirlpool is, for example, shown in FIGS.
As shown in FIG. 0, a circulation pump 100, a suction port 102 for sucking hot water from inside a bathtub 101, an air intake 103, an aeration unit 104, and a jet port 1 for jetting hot water mixed with air bubbles.
05, a pipe 106 for connecting these parts and passing and circulating hot and cold water.

[0004]

In such a jet bath, the spouts are arranged dispersedly on the inner peripheral surface of the bathtub, and hot and cold water is spouted from the spouts in a certain direction in the direction immediately before or the like. It was fixed so as to make it monotonous and had little change.

[0005] As a result, the massage effect provided by the whirlpool is limited to the same part of the body of the bather, and a large relaxing feeling cannot be obtained.

In view of the above circumstances, an object of the present invention is to provide a tornado jet bath which generates a powerful massage effect and a relaxing effect by generating powerful dynamic convection.

[0007]

That is, the invention according to claim 1 has an injection system comprising a pump, a hot water inlet, hot water and air outlets, and a circulation path connecting these members. In a jet bath configured to jet hot water mixed with air bubbles toward hot water in the bathtub,
At least three or more of the spouts are installed on the same inner peripheral surface in the bathtub, and hot water mixed with air bubbles is spouted from these spouts in an appropriate order to form a spiral convection in the bathtub. It is configured to generate hot and cold water.

[0008]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2
1 shows a tornado jet bath according to the present invention. In this tornado jet bath, four jet ports 2 are concentrically (conformally) formed on the same inner peripheral surface of the bathtub 1. (First ejection port 2A to fourth ejection port 2D), and each of branch pipes (circulation paths) 3A to 3D connecting these ejection ports 2 respectively has an electromagnetic valve (first valve) near the ejection port. To 4th valve) 4A to 4D are formed. In addition, in FIG. 1 and FIG.
5 indicates a pump and 6 indicates an air intake.

The jet port 2 of this embodiment is rotatably installed by an angle adjusting means 7 as shown in FIG. 3, for example, so that the jet direction can be changed. For example, as shown in FIG. 5, when facing each other outward, a convection in which the tornado gradually spreads can be formed, and as shown in FIG. 6, when facing each other inward, the tornado gradually narrows. Such convection can be formed. Further, if a mechanism for automatically rotating the ejection ports is provided, for example, each ejection port is inclined inward so that the radius of an envelope formed by connecting the four ejection ports gradually decreases. By going, tornado
It is also possible to add a function of generating convection in a spiral (vortex) shape instead of a shape. Note that the number and positions of the injection ports can be appropriately set according to the directivity, the strength of preference, and the like. Further, the angle adjusting means is not limited to the one in this embodiment, but may be of any appropriate structure.

The solenoid valves 4A to 4D are, as shown in FIG.
The operation is controlled by the control unit 8, and when, for example, the normal rotation mode is selected by an operation button (not shown), the operation is performed in the clockwise order, that is, the first valve, the second valve, the third valve, the fourth valve, and the 1
Each solenoid valve cyclically repeats the opening / closing operation (at a fixed time interval) in the order of the valve,.... In the reverse rotation mode, as shown in FIG. 7, the solenoid valves operate in the counterclockwise order, that is, in the order of the fourth valve, the third valve, the second valve, the first valve, the fourth valve,. While these modes are set, a tornado-like convection is formed in the bathtub as shown in FIG. In the mixing mode, the control unit 8 controls the opening / closing operation so that the operation order of the solenoid valve is alternately switched in two directions, clockwise and counterclockwise.

[0011]

As described above, according to the present invention, at least three or more spouts are provided on the same inner peripheral surface in the bathtub, and air bubbles are formed in an appropriate order from these spouts. It is configured so that hot water mixed with water is blown out and a spiral convection is generated in the hot water in the bathtub.
A powerful dynamic spiral convection can be generated, and a large massage effect and a relaxing effect can be obtained.

According to the second aspect of the present invention, in the configuration in which the direction of each nozzle of the injection port can be adjusted, the degree of spread of the tornado can be changed by adjusting the direction. In addition, it is possible to respond to detailed requests according to the user's preference, such as realizing a tornado flow having a desired strength.
