Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, a pipe 2 in which water is circulated by a pump 1.
In the middle of the flow, a so-called aspirator structure is constructed, consisting of a nozzle part 9 whose flow path cross section is narrowed from the upstream side of the water flow toward the downstream side, and an air suction pipe 11 connected to the side surface of the pipe of the downstream part 10 of the nozzle part. It is attached to the side of the bathtub 12 so that the jet stream is discharged into the bathtub. The bubble jet discharge port 13 from which the jet is discharged is spherically fitted so that the discharge direction can be changed. Further, three parallel flow paths 14, 15, 16 are formed in the pipe line 2 leading from the pump 1 to the nozzle section 9, and two of the parallel flow paths 14, 15 are provided with electromagnetic valves 17, which are jetting control means, respectively. .18, and the three parallel flow paths 14, 15, and 16 have different flow path resistances: small, medium, and large. Reference numeral 19 denotes a compact disc for recording music and a compact disc player for reproducing the same, as an example of a fluctuation signal generating means. When the compact disc player 19 is operated, a fluctuation signal is output. The music, which is this fluctuation signal, is input to the speaker 20, which is a sounding body, and the fluctuation element detection means 21. This fluctuation element detection means 21 includes a zero volt switch 22
and a counter 23 that counts the output of the zero volt switch 22. The counting result of the counter 23 is input to the ejection controller 24. The ejection controller 24 has a microcomputer and an oscillator that oscillates at a constant cycle, and each time a pulse signal from the oscillator is input, the ejection controller 24 reads the counting result of the counter 23 and calculates the counting result from the counting result. The speaker 20, which is a zero-sounding unit that transmits a corresponding ejection control signal to the electromagnetic valve 17, 18, which is an ejection control means, is attached to the wall or ceiling of the bathroom.

Next, the operation of the configuration of the embodiment will be explained. First, when the compact disc player 19, which is the fluctuation signal generating means, is operated from a bathroom remote control (not shown) installed in the bathroom, a musical tone signal is generated. Detect the zero cross of this musical tone signal with zero volt switch '+22,
The microcomputer reads the counting result of the counter 23 at every oscillation pulse interval of the 0 oscillator counted by the zero cross number seven counter 23, that is, every oscillation period is. That is, the zero volt switch 22 and the counter 23 detect pitch (sound height), which is a fluctuation element, at every pulse interval ts. In other words, treble sounds have a higher frequency and a greater number of zero crossings than low bass sounds.

The ejection controller 24 controls the electromagnetic valve 17, which is ejection control means, according to the count result of the counter 23. It acts to change the jetting flow rate by transmitting a jetting control signal that turns on and off the IS. In other words, when both electromagnetic valves 17 and 18 are in a closed state with the electric signals turned off, the water sent from pump 1 flows in parallel w! It reaches the nozzle part 9 through only 16. In this case, since the parallel flow path 16 has the highest flow resistance, the flow rate of water passing through the nozzle portion 9 is the lowest. Therefore, the ejector effect generated in the downstream part 10 of the nozzle part is also minimized, and the amount of air sucked in from the air suction pipe 11 is minimized. As a result, the flow rate of the bubble jet discharged from the bubble jet outlet 13 into the bathtub 12 becomes the minimum flow rate. Further, when the electric signal to the solenoid valve 17 is turned on and opened, the water sent from the pump 1 flows through the parallel flow path 14.
and reaches the nozzle section 9 through the parallel flow path 16. In this case, since the parallel flow path 14 has the lowest flow resistance, the flow rate of water passing through the nozzle portion 9 is the highest. Therefore, the ejector effect generated in the downstream part 10 of the nozzle part is also the largest, and the amount of air sucked in from the air suction pipe 11 is the largest. As a result, the bubble jet outlet 13
The flow rate of the bubble jet discharged into the bathtub 12 becomes the maximum flow rate. Furthermore, when only the solenoid valve 18 is opened, the water sent from the pump 1 is transferred to the parallel flow path 15 and the parallel flow path 16.
The nozzle part 9 is reached through the nozzle part 9. In this case, since the parallel flow path 15 has a medium flow path resistance, the flow rate of water passing through the nozzle portion 9 is a medium flow rate. Therefore, the ejector effect generated in the downstream part 10 of the nozzle part is also moderate, and the amount of air sucked from the air suction pipe 11 is also moderate.

As a result, the flow rate of the bubble jet discharged from the bubble jet outlet 13 into the bathtub 12 becomes an intermediate flow rate. Based on the above principle, the ejection flow rate changes in conjunction with the fluctuation signal.

That is, in conjunction with the music heard from the speaker 20,
The ejection flow rate and ejection speed of the bubble jet ejected into the bathtub 12 can be changed, and the bather can listen to the music from the fluctuation signal generation means 19 such as a compact disc player through the sounding device 20 such as a speaker. The state of the bubble jet changes in conjunction with changes in the volume or pitch of the music, creating a musical stimulation of the body that creates a fun mood through both the so-called body sonic effect and the visual effect of changes in the bubble jet. You can feel the effect.

In the above embodiment, the pitch of music is detected as a fluctuation element, but the same effect can be obtained by detecting other elements such as loudness. Further, the fluctuation signal generating means may be a compact disc player, a cassette tape player, or any other device that generates an electric signal such as 1/f fluctuation, such as an IC card or a computer oscillation circuit. However, by changing the bubble jet in conjunction with the fluctuation signal, you can always enjoy the pleasure of a comfortable bubble bath.

Further, in the above embodiment, a configuration has been described in which the ejection flow rate and ejection speed of the bubble jet are varied by the ejection control means of the electromagnetic valves 17 and 18. By providing a plurality of solenoid valves 17, 18 in the bathtub 12 and opening and closing the plurality of bubble jet outlets, it is possible to change the jetting pattern of the bubble jet in the bathtub 12 in conjunction with the fluctuation signal. It becomes possible. In addition, in FIG. 1, the bubble jet discharge port 13 is shown to have a configuration in which the direction in which the jet is discharged can be manually varied, but this direction can be changed by, for example, a motor, and the electric signal from the jet controller 24 is used to control the By configuring the motor to be driven, the ejection direction can be made variable in conjunction with the fluctuation signal. The bathroom remote control can also arbitrarily start, stop, and adjust the volume of the compact disc that is the source of the fluctuation signal. It is also possible to use the jet flow state only in conjunction with the fluctuation signal from the fluctuation signal generating means 19 without sound from the speaker.

Also, depending on the loudness (volume) of the musical tone fluctuation signal,
The flow rate and intensity (velocity) of the bubble jet can be varied. In other words, when the music is loud, the jet is strong, and when the music is low, the jet is weak. In other words, this means that when the jet is strong and the sound of the jet is loud, the music can be heard loud, and when the music is low, the jet is weak and the sound of the jet is low, so the music can always be heard clearly. can be obtained.

Next, another embodiment of the jet bath apparatus will be described.

In the embodiment shown in FIG. 2, in the middle of a pipe 2 through which water is circulated by a pump 1, there is a nozzle part 9 whose cross section is narrowed from the upstream side to the downstream side of the water flow, and a downstream part 10 of the nozzle part. It constitutes a so-called aspirator structure consisting of an air suction pipe 11 connected to a pipe line, and is attached to the side of the bathtub 12 so that the jet is discharged into the bathtub. facing inward. 19 is a sound 2J as an example of a fluctuation signal generating means! There is a compact disc for recording, and a compact disc player for reproducing it. compact disc player 19
When activated, a music fluctuation signal is output. This music fluctuation signal is input to the speaker 20, which is a sounding body, and the fluctuation element detection means 21. The fluctuation element signal from the fluctuation element detection means 21 is input manually to the flow rate controller 25, and the flow rate control signal from the flow rate controller 25 is further input to the pump 1.

This configuration is different from the previously described embodiment shown in FIG. By varying the suction and discharge flow rate, the ejection flow rate of the bubble jet can be varied in conjunction with the fluctuation signal. That is, based on the fluctuation signal from the fluctuation signal generating means 19 of a compact disc player, etc., the flow rate of the pump 1 that takes in and discharges hot water changes in conjunction with the fluctuation signal, and accordingly, the ejection flow rate of the bubble jet changes. Changes according to changes in the fluctuation signal. In particular, it is possible to change the flow rate and velocity (force) of the bubble jet over time with a simple configuration without requiring a flow rate control valve or the like to change the jet flow rate. Compared to a jet stream, the acclimatization phenomenon is alleviated,
It is possible to always have a comfortable and enjoyable jet bath that provides a lasting feeling of comfort. That is, the pump 1 serving as the flow rate control means is, for example, a centrifugal pump generally called a Hugal pump, which uses a motor to rotate a centrifugal impeller and uses the centrifugal force of the rotation to draw in and discharge hot water, and the rotational speed of the motor is varied. As a result, the rotational speed of the centrifugal impeller changes, and the suction and discharge flow rate also changes. As a result, the flow rate and speed of the bubble jet can be adjusted based on the fluctuation signal from the fluctuation signal generating means 19 such as a compact disc player with a simple configuration without requiring a flow control valve or the like for changing the jet flow. (force) etc. can be varied, making it possible to maintain a comfortable and pleasant jet bath.

Furthermore, another embodiment of the jet bath apparatus will be described. In the embodiment shown in FIG. 3, a nozzle portion 9 and a nozzle downstream portion 10 are provided in the middle of a pipe line 2 through which water is circulated by a pump 1 to narrow the cross section of the water flow from the upstream side to the downstream side.
It constitutes a so-called aspirator structure consisting of an air suction pipe 11 connected to a pipe line, and is attached to the side of the bathtub 12 so that the jet is discharged into the bathtub. 12 facing inward.

Reference numeral 19 denotes a compact disc for recording the chirping of birds, the sound of rustling leaves, or the sound of a babbling stream, as an example of a fluctuation signal generating means, and a compact disc player for reproducing the same. When the compact disc player 19 is operated, a fluctuation signal is output. This fluctuation signal is input to the speaker 20, which is a sounding body, and the fluctuation element detection means 21. The fluctuation element signal from the fluctuation element detection means 21 is input to an air controller 26, and the air control signal from the air controller 26 is further input to an air control valve 27 which is an air amount variable means.

This configuration differs from the previously described embodiment shown in FIG.
The air amount variable means 27 changes the flow path resistance of the air suction flow path, thereby changing mainly the amount of bubbles in the bubble jet in conjunction with the fluctuation signal.

That is, based on the fluctuation signal from the fluctuation signal generating means 19 of a compact disc player, etc., air control is provided in a part of the air suction pipe 11, which is the air supply path for sucking air into the water flow by the ejector effect. The valve opening degree of the valve 27 changes in conjunction with the music, and the amount of air supplied for bubble generation is controlled accordingly;
The ratio of bubbles to water in the bubble jet changes in response to changes in the fluctuation signal. Air control valve 2 as air amount variable means
7 in the air suction channel and the air control valve 27 is driven based on the fluctuation signal, the amount of bubbles in the bubble jet can be varied with fluctuations, making it possible to maintain a comfortable and enjoyable jet bath. . That is, the air control valve 27, which is the air amount variable means, is, for example, an electric control valve generally called a motor valve or a motor damper, and by varying the opening degree of the flow path, the flow path resistance of the air supply path is changed. ,
It also works to change the amount of air intake.

As a result, with such a simple configuration, the amount of bubbles in the bubble jet can be varied based on the fluctuation signal from the fluctuation signal generating means 19 such as a compact diffuse player, making it possible to maintain a comfortable and enjoyable jet bath. This means that it is possible to do so.

a jet controller that outputs a jet control signal that changes at least one of a jet pattern or a jet direction; and a jet control that receives the jet control signal and operates at least one of a jet flow rate, a jet speed, a jet pattern, or a jet direction. Since the bather is equipped with means, the state of the bubble jet changes in conjunction with changes in the fluctuation signal from the fluctuation signal generating means such as a compact disc player, and the bather can experience physical stimulation due to the fluctuating bubble jet. , it is possible to produce an effect that creates a pleasant mood from both the visual effect of the change in the bubble jet and the effect that creates a pleasant mood.

Further, the jet bath device of the present invention includes a pipe and a pump for sucking and discharging hot water, a nozzle part with a narrowed cross section of the flow passage in the middle of the pipe, and an air intake connected to the pipe at a downstream part of the nozzle part. The pump includes a pipe, a bubble jet discharge port, a fluctuation signal generating means, and a flow rate controller that outputs a flow rate control signal for varying the flow rate of the pump based on the fluctuation signal from the fluctuation signal generating means. Therefore, the flow rate and speed (force) of the bubble jet can be changed over time based on the fluctuation signal from the fluctuation signal generating means with a simple configuration without requiring a flow control valve or the like to change the jet flow rate. Compared to conventional jets of constant bubbles, this allows for a so-called variable fluctuation, which alleviates the acclimatization phenomenon experienced by the body, making it possible to maintain a comfortable and enjoyable jet bath.

Furthermore, the jet bath device of the present invention includes a nozzle part with a narrowed flow passage cross section in the middle of a pipe line for discharging hot water, an air suction pipe connected to a pipe line at a downstream part of the nozzle part, and a An air controller that outputs an air control signal that varies the flow path resistance of the air amount variable means based on the fluctuation signal from the fluctuation signal generating means, the air amount variable means provided in a part, and the fluctuation signal generating means.
