The above-described six jet modes (mild blow, acupressure blow, pulse blow, massage blow, wave blow, and air pulse blow) will be described.

The mild blow is a jet form in which a large amount of hot water is spouted from a spout nozzle and the jet pressure is low, and the mild blow softly wraps the entire body of the bather to stimulate the bather.

When using mild blow, air intake section (5)

Pulse blow is performed for each ejection nozzle (2) (3)
This is a jet form in which (4) is periodically opened and closed to alternately eject and stop the bath water. By pulsating or not emitting the jet, a sharp stimulus can be given to a bather. Things.

In other words, in the pulse blowing, in the acupressure blowing, the ejection amount adjusting valve body (22) of each ejection nozzle (2) (3) (4) is moved between the fully open position and the fully closed position in as short a time as possible. The bath is reciprocated to alternately generate a state in which the bath is spouted and a state in which the bath is not spouted, thereby giving a pulsating stimulus to the bather.

When the bath water is ejected, there are cases where bubbles are contained and cases where bubbles are not contained.

And the change of the strength level of the pulse blow is
It is possible to set the amount of bath water to be jetted in several steps within a certain range.

The pulse blow is activated by turning on the air pulse blow switch (79) of the remote controller (30).

(4) The bath water is simultaneously jetted from (4), the circulation use pattern switch (73) is turned ON, and the bath water is jetted periodically and alternately from each jet nozzle. In some cases, 1 or 2 is selected from (3) and (4), and bath water is jetted from the jet nozzle.

When pulse blow is used, the opening / closing operation cycle of the ejection amount adjusting valve body (22) of each ejection nozzle is controlled by a cycle increase / decrease switch (70) (71) of the remote controller (30).
Thus, for example, adjustment is made in five stages of 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds, so that the pulsation feeling given to the bather can be varied.

Massage blows each jet nozzle (2) (3)
This is a jet form in which the amount and pressure of the bath water from (4) are periodically changed to alternately perform the mild blow and the acupressure blow. Are given alternately.

That is, in the massage blow, the air amount adjusting valve (5d) of the air intake section (5) is fully opened, the rotation speed of the circulation pump (P) is kept constant, and each jet nozzle (2)
(3) By gradually decreasing or gradually increasing the opening degree of the ejection amount adjusting valve element (22) of (4), the change of the ejection amount of the bath water from each ejection nozzle, the change of the ejection pressure, Is performed periodically to give the bather a mild feeling and a shiatsu feeling.

In addition, such a change in the level of the massage blow can be achieved by changing the amount of bath water spouted by several steps (for example, five steps).
Can be set.

The massage blow is operated by turning on a massage blow switch (64) of the remote controller (30).

Further, the cycle in the above-mentioned circulation use pattern can be made to coincide with the above-mentioned cycle in which the rotation speed of the circulation pump (P) changes.

The air pulse blow is a jet flow in which the air intake time and the air intake stop time are periodically changed by the air intake section (5) to alternately eject a bubble-containing bath water and a bubble-free bath water. This is a form in which the bather is given a stimulus different from the pulse blow based on the strength of the above-mentioned bathwater jet.

That is, the air pulse blow is performed in the acupressure blow by alternately repeating the full-opening operation and the full-closing operation of the air bubble amount control valve (5d) of the air intake section (5) at a constant cycle, thereby providing a bubble-mixing bath. The hot water and the hot water in which bubbles are not mixed are ejected alternately.

The air pulse blow is activated by turning on an air pulse blow switch (63) of the remote controller (30).

In addition, the usage pattern of the ejection nozzles for ejecting the bath water of the air pulse blow is such that the ejection nozzle use pattern switch (72) is turned on and the four ejection nozzles (2) are turned on.
(2) (4) (4) Simultaneously ejecting bath water from each ejection nozzle (2) (4) by turning on the circulation use pattern switch (73) and simultaneously ejecting bath water from (4) and (4). And one from each of the ejection nozzles (2), (3), and (4).
There is a case where the bath water is jetted from the jet nozzle by selecting from No. 2 to No. 2.

When pulse blow is used, the opening / closing operation cycle of the air volume control valve (5d) of the air intake section (5) is set to, for example, 1 second by the cycle increase / decrease switches (70) (71) of the remote controller (30). Adjustment is made in five steps of 2 seconds, 3 seconds, 4 seconds, and 5 seconds so that the stimulus given to the bather can be varied.

As described above, the bubble-generating bath (A) of the present invention has the foot-side jet nozzles (2) and (2), the back-side jet nozzles (3) and (3) except for those controlled by the circulation pump (P). The ventral ejection nozzles (4) and (4) can individually exhibit five types of ejection modes. When these are combined, 125 ejection nozzle usage patterns can be exhibited. In addition, the mode of spraying the bath water and bubbles in the bubble generating bath (A) can be made very various.

 The following table shows typical spray nozzle usage patterns.

Also, by turning on the filter washing switch (77) provided in the remote controller (30), the electric three-way valve (45) is switched to operate, so that the filter (43) can be backwashed. I have to.

(E) Effects The present invention has the following effects.

Since each ejection nozzle is provided with ejection amount adjustment means,
By adjusting the ejection amount adjusting means of each ejection nozzle, the ejection amount of bath water ejected from one ejection nozzle is individually controlled so that the ejection amount of bath water ejected from each ejection nozzle is different from each other. This makes it possible to realize a variety of blow modes that are rich in changes, improve the comfort of using the bubble generation bathtub, and improve the massage effect of the bubble generation bathtub.

Since each jet nozzle has a bubble amount adjusting means,
By adjusting the bubble amount adjusting means of each ejection nozzle, the bubble amount of the bath water ejected from one ejection nozzle is individually controlled so that the bubble amount of the bath water ejected from each ejection nozzle is different from each other. This also makes it possible to realize a variety of blowing modes that are rich in changes, improve the comfort of using the bubble generation bathtub, and improve the massage effect of the bubble generation bathtub.

Since the ejection nozzles are provided on the foot side and the back side, the ejection amount and the bubble amount on the foot side and the back side can be individually controlled, and thereby the foot side and the back side are rich in changes, respectively. By realizing various blow modes, the comfort of using the bubble generation bathtub can be improved, and the massage effect of the bubble generation bathtub can be improved.
