〔Example〕

Hereinafter, some embodiments of the present invention will be described with reference to the drawings.

1 / f-type fluctuation generating means is a 1 / f-type fluctuation generating means which applies a DC voltage to both ends of solid carbon and takes out a 1 / f-type fluctuation current generated by the carbon resistance as a voltage value. There are various types such as a type in which a 1 / f-type fluctuation voltage generated from a memory is stored in a memory. In the present embodiment, an example in which a computer generates 1 / f type fluctuation will be described. That is, as shown in FIG. 1, a numerical sequence having 1 / f-type fluctuation is stored in a ROM 2 provided inside the computer 1, and the stored value is output from the computer 1 as a digital signal, and the 1 / f-type fluctuation is output. Is generated.

The digital / analog converter 3 converts information of a numerical sequence having a 1 / f type fluctuation from the computer 1 into an analog signal.

The DC power supply circuit 4 whose voltage value fluctuates in a 1 / f type (hereinafter referred to as a power supply circuit 4) is configured to be controlled by the analog signal so that the DC voltage changes in accordance with the 1 / f type fluctuation.

The motor 5 is driven by the DC power supply circuit 4 and is driven and rotated by a 1 / f-type fluctuation DC voltage. The DC power supply of the DC power supply circuit for driving the motor 5 may be obtained by removing a spectrum having a large amplitude change from the 1 / f fluctuation signal from the analog signal through a low-pass filter.
As a means for rotating and driving the motor by a DC power supply having a 1 / f fluctuation voltage, a known method is used. In one example, a pulse motor is used as a motor, and the 1 / f fluctuation voltage of the DC power supply is converted into a pulse train having a constant width proportional to the magnitude of the voltage. The converted pulse train is supplied to a pulse motor. With this method, the pulse motor is 1 / f
It is driven to rotate in proportion to the fluctuation voltage.

The bath tub recirculation device 6 includes various devices described below, each of which is a device for recirculating bath water taken out of the bath tub into the bath tub with 1 / f type fluctuation.

When solid carbon is used as the means for generating the 1 / f-type fluctuation, a DC voltage is applied to both ends of the solid carbon in place of the computer 1 and the digital / analog converter 3 shown in FIG. And an amplifier circuit for 1 / f-type fluctuation current extracted from the electric circuit through, for example, a capacitor.

 FIG. 2 shows a first embodiment of the bath tub recirculation device 6.

This embodiment includes a jet pump 9 and a pump 10 driven by a motor 5 driven by 1 / f-type fluctuation.

The jet pump 9 is of a known technology, and the fluid introduced from the pipe 11 is ejected from the nozzle 12 when
A fluid, for example, air from the air is discharged, and a mixed bubble water of the fluid and the air is ejected from the nozzle 14. In this embodiment, the pipe 11 is connected to the pump 10, and the pump 10 is connected to the bath 8. Pump 10
Is directly driven by the motor 5 driven by 1 / f fluctuation, the flow rate of the bathtub water 7 flowing out of the pump 10 is in principle proportional to the rotation of the motor 5. For this reason, the bath water 7 whose flow rate changes with a 1 / f-type fluctuation is sent from the pump 10 to the pipe 11 side. Therefore, as a result, the bathtub water 7 of the 1 / f type fluctuation in which bubbles are mixed is injected into the bathtub 8.

 FIG. 3 shows a second embodiment of the bathtub water recirculation device 6.

This embodiment includes a known bubble pump 15 and a pump 16 driven by a 1 / f-type fluctuation motor 5.

The bubble pump 15 is a reservoir for temporarily storing the bath water 7.
Tube 18 connected to suction pump 16 so as to reach deep in 17
And a hole for the compressed air sent from the compressor 19.
Air is sent to the lower end of 17 to create a bubble, and the bathtub water 7 is pumped together with the bubble.

Since the pump 16 is driven by the 1 / f-type fluctuation motor 5 as in the first embodiment, the bath water 7 containing air bubbles pumped by the pump 16 is returned to the bathtub 8 by the 1 / f-type fluctuation. Will be.

FIG. 4 shows a third embodiment of the bath tub water recirculation device 6.

In the present embodiment, a known nozzle flapper 20 and a cam mechanism 21 driven by a 1 / f-type fluctuation motor 5 are provided. The nozzle flapper 20 uses a nozzle 22, a flapper 23 and an orifice 24 to convert mechanical displacement into a change in fluid pressure.The mechanical displacement of the input is transmitted to the flapper 23, and when the flapper 23 moves relative to the nozzle 22, Since the flow resistance between the nozzle 22 and the flapper 23 changes, the pressure in the nozzle 23 and the orifice 24, that is, the nozzle back pressure changes. Using this nozzle back pressure as an output, the bath water 8 is introduced into the orifice 24 side by the pump 25 and is to be sent out from the discharge pipe 26.

The cam 27 of the cam mechanism 21 forms its cam contour from an Archimedes curve, and a rod 29 corresponding to a cam follower is connected on the same line as its rotating shaft 28 by abutting the tip of the cam contour. The rod 29 is slidably guided on the fixed side 30 of the device and connects to the flapper 23.

When the cam profile of the cam 27 is formed from the Archimedes curve, the rod 29 moves in proportion to the rotation angle of the rotation shaft 28, and moves at a constant speed. Since the rotating shaft 28 is rotated by the 1 / f-type fluctuation motor 5, the rod 29 linearly moves with the 1 / f-type fluctuation and gives the flapper 23 connected thereto a 1 / f fluctuation swing. . As a result, 1 / f fluctuation bathtub water is sent from the drain pipe 26 of the nozzle flapper 20 to the bathtub 8 side.

FIG. 5 shows a fourth embodiment of the bathtub water recirculation device 6.

This embodiment includes a butterfly valve mechanism 31 and a cam mechanism 32 driven by a motor 5 with 1 / f fluctuation.

A valve seat 35 and a butterfly valve 36 that abuts on the valve seat 35 are disposed in a pipe 34 that is connected to the bathtub 8 via a pump 43 and is connected again to the bathtub 8 via a pipe 33.

On the other hand, the cam mechanism 32 includes a cam 37 rotated by the 1 / f-type fluctuation motor 5 and a rod 38 corresponding to a cam floor that comes into contact with the cam 37.
Connect to 39. The cam profile 39 of the cam 37 has an Archimedes curve, and the cam 37 and the rod 38 are disposed on the same plane. When the rod 40 moves up and down, the butterfly valve 36 swings, and the opening and closing of the passage in the pipe 34 is adjusted. A spring 42 is interposed between the pipes 34 of the spring seat 41 fixed to the rod 38, and the butterfly valve 36 is connected to the valve seat 35.
Is pressed in a direction close to the

With the above configuration, when the cam 37 is rotated by the motor 5 with the 1 / f fluctuation, the rod 38 moves up and down with the 1 / f fluctuation, and accordingly, the butterfly valve 36 swings at the 1 / f fluctuation. For this reason, the bathtub water taken out of the bathtub 8 by the pump 32 passes through the gap between the butterfly valve 36 and the valve seat 35 which opens with 1 / f fluctuation.
The bathtub water 7 enters the bathtub 8 via the pipeline 33 in a state of 1 / f fluctuation.
Will be circulated.

As described above, according to any of the embodiments, bathtub water or bubble bathtub water in which bubbles are mixed therein is circulated in the bathtub 8 in a 1 / f-type fluctuation state, and gives a stimulus of 1 / f fluctuation to the bather. be able to.

Although the first to fourth embodiments have been described as the bath tub recirculation device 6, other devices having the same structure are also applicable. Also 1 /
The means for generating the f-type fluctuation is not limited to that of the present embodiment as described above.
