Depending on the combination, the amount of bath water spouted from each jet nozzle,
You can set six types of jet modes (mild blow, shiatsu blow, pulse blow, pine surge blow, wave blow, and air pulse blow) with differences in jet pressure and amount of air bubbles mixed in. Each jet mode can be controlled using the remote controller ( Select the desired jet mode switch (6) provided on

By turning on and off 1), it is possible to increase or decrease the amount of bubbles, adjust the strength of the hot water that spouts, and adjust the period of the hot water that spouts. In addition, by turning on the filter cleaning switch (77) provided on the remote controller (30), the electric three-way valve (45) can be operated to perform backflow cleaning of the filter (43). I have to. As described above, in the bubble generating bathtub (A) of the present invention, the rotation speed of the circulation pump (P) can be controlled steplessly by the inverter (1), and the foot side jet nozzle (2)
(2) The amount of hot water spouted from the dorsal side jet nozzle (3) (3) and the ventral side jet nozzle (4) (4) can be controlled individually, and the amount of air bubbles mixed into the bath water is controlled by the air bubble amount control valve (5d). Since the amount of air can be adjusted, a wide variety of bath water injection modes can be achieved. In other words, all the jet nozzles (2) (2) (3) (3) (4) (4
), the amount of hot water spout can be adjusted steplessly.
And each jet nozzle (2) (2) (3) (3)
(4) The amount of hot water spouted from each nozzle can be controlled individually with (4), and the bubble amount control valve (5d) can be used to control all the spout nozzles (2) (2) (3) (3) (4) Since it can be mixed into the bath water spouted from (4), by combining these, an extremely wide variety of bath water injection modes can be realized. Next, a typical aspect of bath water injection will be illustrated and explained. However, in this embodiment, for the convenience of the user, the following injection patterns are set corresponding to each switch provided on the remote controller (30), and each of the changeover switches (72) to By turning on and off (7B), you can use 6 types of jet modes (mild blow, shiatsu blow, pulse blow, pine surge blow, wave blow, and air pulse blow) and 6 jet nozzles that apply each jet mode. The pattern and amount of air bubbles can be selected. ■ Mild blow is a type of jet flow in which the amount of hot water spouted from the spout nozzle is high or the jet pressure is low, and it is mild and soft and envelops the entire body of the bather, stimulating the bather. It is. In addition, when using Mild Solo, the air bubble volume control valve (5d) of the air intake part (5) can be connected to the i-controller (30
), the air bubble volume increase/decrease switch (6B) (67) is operated to adjust the air bubble volume, thereby making it possible to change the mildness of the bather's body. Moreover, the usage pattern of the jet nozzles that spout such mild blow bath water is such that the all jet nozzle usage pattern switch (72) is ONL, and the six all jet nozzles (2>
(2) (3) (3) (4) (4) When the bath water is spouted out at the same time, and when the circulation use pattern switch (73
) is turned ON and bath water is periodically spewed out from each spout nozzle (2), (3), and (4,);
) (3) In some cases, bath water is spouted from the spout nozzle by selecting from (4). ■ Shiatsu blowing is a type of jet flow in which the amount of hot water jetted from each jetting nozzle (2), (3), and (4) is small or the jetting pressure is high. By applying this, the bather can experience acupressure sensation. In addition, when using acupressure blow, the air bubble amount can be adjusted by operating the air bubble amount adjustment valve (5d) of the air intake part (5) with the air bubble amount increase/decrease switch (86) (67) of the remote controller (30). This makes it possible to vary the sensation of acupressure applied to the bather's body. Moreover, the usage pattern of the jet nozzles for spouting the bath water of such acupressure blow is to turn on the jet nozzle all usage pattern switch 72), and then turn on the six all jet nozzles (2) (
2) (3) (3) (4) When the bath water is spouted out at the same time from (4), and the circulation usage pattern switch (73)
is turned ON and bath water is periodically spouted from each spout nozzle (2), (3), and (4), and when each spout nozzle (2)
), (3), and (4), and the bath water may be spouted from the spout nozzle. (■ Pulse blow uses individual jet nozzles (2) (3)
(4) is opened and closed periodically, and the jet flow alternately spouts and stops, and by emitting and not emitting the jet in pulses, it can give a sharp stimulation to the bather. It is something. That is, in the pulse blow, in the acupressure blow,
The spout amount adjusting valve body 22) of each spout nozzle (2), (3), and (4) is moved back and forth between the fully open position and the fully closed position in as short a time as possible to spout bath water. This creates a pulsating stimulation to the bather by alternating between the state and the state where the bath water does not gush (7).
It is designed to make it easier to read. Note that when the bath water is ejected, there are cases in which bubbles are included and cases in which bubbles are not included. By changing the strength level of the pulse blow, the amount of hot water jetted out can be set in several stages within a certain range. In addition, such pulse blow can be controlled by the remote controller (
It is activated by turning on the air pulse blow switch (79) (30). Moreover, the usage pattern of the jet nozzles for spouting such pulse-blown bath water is to turn on the all jet nozzle usage pattern switch (72), and use the four jet nozzles (2) (
2) (4) If the bath water is spouted out at the same time from (4), turn on the circulation pattern switch (73). In the case where the bath water is spouted periodically and alternately from each spout nozzle, and when the hot water is spouted alternately from each spout nozzle (2) (3) (4)
2 may be selected and bath water is spouted from the spout nozzle. In addition, when using a pulse blow, the opening/closing cycle of the valve body (22) for adjusting the jetting amount of each jetting nozzle is controlled by the period increasing/decreasing switch (70) (7) of the remote controller valve 30).
In 1), for example, the time can be adjusted in five stages: 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds, so that the pulsating sensation given to the bather can be varied. ■ Pine Surge Blow uses each jet nozzle (2) (3) (
4) Periodically change the amount and pressure of the bath water from
It is a jet type that alternately performs the mild blow and the acupressure blow, and alternately gives the bather the mildness of the mild blow and the acupressure sensation of the acupressure blow. That is, in the pine surge blow, the air bubble amount control valve (5d) of the air intake part (5) is fully opened, and the circulation pump (
While maintaining the rotation speed of P) constant, each jet nozzle (2) (
3) Gradually decrease or gradually increase the opening degree of the spout amount regulating valve body (22) in (4) to increase or decrease the amount of bath water spouted from each spout nozzle and change the intensity of the spout pressure. This is done periodically to give the bather a mild and shiatsu sensation. The strength level of the pine surge blow can be changed by setting the increase/decrease in the amount of bath water spouted in several stages (for example, five stages). The pine surge blow is performed by turning the pine surge blow switch (64) of the remote controller (30) on.
It is activated by turning it to N. Moreover, the usage pattern of the spout nozzles for spouting the bath water of such Pine Surge Blow is that the pattern for using all spout nozzles (72) is turned on and the four spout nozzles (2) are used.
(2) (4) (4> When simultaneously spouting hot water, turn on the circulation pattern switch (73),
When bath water is periodically and alternately spouted from each spout nozzle (2>(4)), and when each spout nozzle (2) (3) (4)
1 or 2 may be selected from the following, and bath water may be spouted from the spout nozzle. Also, when using Pine Surge Blow, each jet nozzle (2
) (3) The opening/closing operation cycle of the ejection amount regulating valve body (22) in (4) is set to 1, for example, by the cycle increase/decrease switch (70) (71) of the remote controller (30).
It can be adjusted in five stages: seconds, 2 seconds, 3 seconds, 4 seconds, and 5 seconds, so that the stimulation given to the bather can be varied. ■ Wave blow is a type of jet flow that periodically changes the strength of the ejection pressure of bath water, and by changing the strength and weakness of the ejection amount in slow cycles, it creates an unsteady flow that approaches and returns to the bather. It gives a stimulating image of waves. And, changing the strength level of the wave blow,
In addition to changing the flow rate, the air bubble amount control valve (5d) of the air intake part (5)
), and the larger the amount of bubbles, the stronger the ejection pressure can be. In addition, by changing the strength of the wave blow, for example, you can enjoy a comfortable blow in time with the rhythm of music. In other words, it converts the strength of the music rhythm into the strength of the voltage,
By opening and closing the jet amount regulating valve body (22) in accordance with the same voltage, changes in the strength of the wave blow can be matched to the rhythm of the music. In addition, the wave blow can be used with a remote controller (30
) is activated by turning on the wave blow switch (65). Moreover, the usage pattern of the jet nozzles that jets out bath water in such a wave blow state is that the all jet nozzle usage pattern switch (72) is turned on and the six all jet nozzles (2
) (2) (3) (3) (4) (4) When spouting bath water at the same time, and when turning on the circulation use pattern switch (73), each spout nozzle (2) (3) (
There are cases in which bath water is periodically and alternately spouted from 4), and cases where 1 to 2 are selected from each spout nozzle (2), (3), and (4), and bath water is spouted from the spout nozzle. In addition, when using the wave blow, the cycle for changing the rotation speed of the circulation pump (P) can be controlled using a remote controller (30
) The period increase/decrease switch (70) (71) can be used to adjust to five stages, for example, 2 seconds, 3 seconds, 4 seconds, 6 seconds, and 8 seconds, to change the acupressure effect given to the bather. We are making it possible to do so. Further, the cycle in the above-described circulation usage pattern can be made to match the cycle in which the rotation speed of the circulation pump (P) changes. ■ Air pulse blowing alternately blows out bath water with bubbles and bath water without bubbles by periodically changing the air intake time and air intake stop time by the air intake part (5). It is in the form of a jet stream, and provides a different stimulus to the bather than the pulse blow, which is based on the intensity of the hot water jet described above. That is, in the air pulse blowing, in the above-mentioned acupressure blowing, the air bubble amount control valve (5d) of the air intake part (5) is alternately repeated at a constant cycle between fully open operation and fully closed operation, thereby creating a bath containing air bubbles. Exchange hot water with bath water without air bubbles.
I feel like I'm going to squirt something.1. It's ours. In addition, to perform such a blow, turn the near pulse blow switch (83) of the remote controller (30) on.
It is activated each time it is turned on. Moreover, the usage pattern of the jet nozzles for spouting out the bath water in the air pulse blow is such that the all jet nozzle usage pattern switch (72) is turned ONt, and the four jet nozzles (2
) (2> (4) If the bath water is spouted out at the same time from (4), turn on the circulation pattern switch 73).
7, the case where bath water is periodically and alternately ejected from each ejection nozzle (2) (4), and the case where bath water is ejected alternately from each ejection nozzle (2) (3) (4).
) may be selected and bath water is spouted from the spout nozzle. In addition, when using a pulse blow, the opening/closing operation cycle of the air bubble ML control valve 5d) of the air intake part (5) is controlled by the cycle increase/decrease switch (70) (7) of the remote controller (30).
According to 1), for example, the stimulation 17 can be adjusted to 1d steps of 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds to change the stimulation λ given to bathing thoughts. ``-The deaf style of bath water injection described above is one in which the injection of bath water from each injection nozzle is periodically changed within a certain injection range, but in addition to ``- Then, the bath water jets with different jet modes are alternated from each jet nozzle x7. It can be ejected regularly and periodically. Among the above-mentioned combinations of different injection modes, there are 6C2-15 combinations of two types of injection modes, which are specifically shown in the table below. [Injection mode combination table] In addition, since wave blowing is performed by controlling the rotation speed of the circulation pump (P), the other five types of wave blowing are performed by controlling each injection nozzle and bubble volume control valve (5d). This can be added to the injection mode, and we will introduce several examples of this combination. (e) Effects As described above, in the present invention, the rotation speed of the circulation pump, the amount of bath water spouted from each spout nozzle, and the amount of bubbles mixed in can be individually controlled, so that the amount of bath water and bubbles in the bubble-generating bathtub can be controlled individually. The bubble injection mode can be extremely diverse, and in particular, by alternately and periodically appearing different types of injection modes, the user can enjoy an extremely varied bathing experience. This has the effect of not making the user feel bored and making it possible to satisfy the various wishes of the user.
