DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble jet apparatus used for a bath or the like.

[0002]

2. Description of the Related Art In recent years, there has been an increasing interest in comfort, pleasure, health, and the like with respect to bath life and the like.
BACKGROUND ART A bubble jet device that generates a bubble jet in a bathtub by a jet such as a pump has been increasingly used.

[0003] Conventionally, with regard to this type of bubble jet device, for example, as shown in FIG.
In the middle of the bath, a throttle section 3, an air suction port 4, and a mixing pipe 5 are provided, and a water stream 7 containing air bubbles is jetted out of a bathtub side surface 6, and while the body is rubbed and loosened with a jet of air bubbles during bathing, blood circulation is promoted, There are things that aim to maintain and improve health.

[0004]

However, in the above-mentioned conventional configuration, it was not possible to enjoy a very pleasant feeling. In other words, at the beginning, even a bubble jet that is comfortable for the user,
There has been a problem that a so-called habituation phenomenon is exhibited with the passage of time, and the comfort is finally lost.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a bubble jet apparatus which can maintain comfort and pleasure forever.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a nozzle section for jetting hot water, an air supply path for supplying air to the hot water jet from the nozzle section, and an air supply path. An electrically operated valve provided in a part thereof, a sound source means for generating a sound signal such as a sound of a wave, a crowing of a bird, or music; a speaker driven by a sound signal from the sound source means; Tone element extraction means for extracting a tone element signal such as a rhythm, level detection means for detecting the amplitude of the tone element signal extracted by the tone element extraction means, and change in the tone element signal extracted by the tone element extraction means Differentiating means for detecting an amount, comparing means for comparing the output signals of the level detecting means and the differentiating means to detect a difference, and a valve for electrically outputting to the electrically operated valve according to the difference between the output signals With driving means Has a configuration was.

[0007]

With this structure, the user can take a bath of the bubble jet while listening to music, and the amount and the force of the bubble jet change in accordance with the element signal of the tone signal. In addition, since the differentiating means is used, a change in the bubble jet does not occur or does not occur due to a difference in the source signal level of the tone signal generating means, and the change in the music coincides with the change in the bubble jet.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, a nozzle portion 9 having a narrowed flow passage section is provided on a side surface of the bathtub 8 through a pipe 2 through which hot water in a bathtub 8 is pumped by a pump 1. An outlet 12 of an air supply passage 11 for supplying air to a downstream portion 10 of the nozzle portion 9 is provided so that hot water is jetted into the bathtub 8. An electrically actuated valve 13 composed of a solenoid valve capable of electrically opening and closing the air supply path 11 at high speed is connected to a part of the air supply path 11. Reference numeral 14 denotes a sound source means (for example, a recording / reproducing device such as a compact disk player or a tape recorder or a radio wave receiving / reproducing device such as a radio or a television) for generating a sound signal such as music, waves, and birdsong. Reference numeral 15 denotes a speaker that reproduces a sound signal from the sound source 14. 16
Is a musical sound element extracting means (for example, a filter) for extracting an element signal of music. Reference numeral 17 denotes a differentiating means for detecting a change in the extracted element signal. Reference numeral 18 denotes a level detecting means for detecting the amplitude level of the element signal. Reference numeral 19 denotes comparison means for comparing the level detection value with the differential signal, and the valve driving means 20 outputs an electric signal to the electrically operated valve 13 according to the difference.

Next, the operation of the above configuration will be described. When the user switches on the sound source means 14 from a remote controller (not shown) installed in the bathroom, music is heard from the speaker 15. At the same time, elemental signals such as rhythm signals are extracted from the music signal output from the sound source means 14 by the musical sound element extracting means 16. This element signal is input to the level detecting means 18 to estimate the amplitude level of the music signal recorded in the sound source by the element signal,
At the same time, the element signal is also input to the differentiating means 17, and a change in the element signal is detected. Then, the comparing means 19 sets a judgment level of the differential signal to be compared based on the detected signal level, compares the differentiated signal with a variation signal obtained by differentiation to detect a difference, and the valve driving means 20 detects the difference. A drive signal for the electrically operated valve 13 is generated and output according to the difference. That is, the valve driving means 20 outputs an electric signal for controlling the on / off of the electrically operated valve 13 formed of a solenoid valve according to the output signal from the comparing means 19. By configuring the electrically operated valve 13 by an electromagnetic valve, the state of the bubble jet can be variably controlled in synchronization with a fast change signal such as a rhythm element of music. That is, in response to a change in the tone signal from the sound source means 14, the electric actuation valve 13 provided in the air supply path 11 is provided.
The opening / closing operation frequency and the opening / closing time patterns change. Therefore, the bubble jet jetting out to the bathtub 8 generates or cuts off bubbles in conjunction with a rhythm element such as music transmitted from the sound source means 14.

According to the configuration of this embodiment, the sound source 14
The output signal level is detected by detecting the output signal level even if the output signal level of the output signal becomes smaller or larger depending on the source (normally, the recording level of the music signal is different not only between CDs and tapes but also between CDs). Is set, and a change signal of the element signal is detected and compared by the comparison means 19. Therefore, even if the output level of the music signal fluctuates, the change signal corresponding to the element signal such as the rhythm can be detected without being influenced by the signal level recorded in the music. It can be changed in accordance with a change in the signal, and the conventional disadvantages such as the acclimatization of the sensation caused by the constant bubble jet and the loss of the comfortable feeling can be solved. In addition, the change of the bubble jet is different from the monotonous repetitive change, and the user can enjoy the change of the bubble jet linked to the change of the sound while listening to the sound of a wave, the singing of a bird, or music from the speaker 15, which is comfortable. There is an effect that a bubble jet bath becomes possible. In other words, the bather listens to favorite music and the like from the sound source means 14 such as a compact disc player, and listens to the volume, pitch,
Alternatively, the enjoyment can be enjoyed from both the so-called body sonic effect, which is a musical stimulus to the body caused by the change of the state of the bubble jet in association with the change of the rhythm, and the visual effect of the change of the bubble jet.

[0012]

As described above, according to the bubble jet control apparatus of the present invention, a fluctuation signal always generated in synchronism with a tone signal element without being influenced by a signal level of a tone recorded in a sound source. Since it is possible to control the fluctuation of the bubble amount, it is possible to realize a comfortable bubble jet without monotony.
