Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bathtub health promotion device and a bathtub with a health promotion device that have a heat retention effect, a blood circulation promotion effect, and a negative ion effect.
[0002]
[Prior art]
It is widely known that bathing not only has the effect of washing the body, but also has the effect of healing tiredness of the day and relieving illness such as muscle pain, fatigue and rheumatism.
[0003]
These effects are obtained by warming the body by taking a bath, resulting in improved blood circulation. In order to further enhance such an effect of warming the body (warming effect) and an effect of improving blood circulation (blood circulation promoting effect), it has been proposed to use a magnetic effect in combination.
[0004]
For example, Japanese Patent Application Laid-Open No. 6-142156 proposes a bathtub device having an enhanced heat retaining effect and a blood circulation promoting effect. In this bathtub apparatus, a high-frequency coil device is arranged on the outer peripheral side of the bathtub, and the high-frequency coil is supplied with a high-frequency current to inductively heat the bathtub body to a hot water temperature. To generate a magnetic flux, and the magnetic flux promotes the blood circulation of the bather.
[0005]
In addition to the magnetic action, a device in which the electrode is brought into close contact with the skin to flow a low-frequency current, and a similar effect is obtained by contraction of muscles by the low-frequency current is generally used.
[0006]
[Problems to be solved by the invention]
However, the former device, in which a long high-frequency coil is provided outside the bathtub and in which a high-frequency high current such as boiling water is passed through the high-frequency coil, is expensive and becomes a large-scale device, and furthermore, in the treatment site. Correspondingly, there is a problem that the location and strength of the magnetic flux cannot be adjusted.
[0007]
In the latter method, the treatment site can be adjusted by changing the mounting position of the electrode, but also because the electrode is in close contact with the body while wearing clothes, the clothes interfere with the attachment and detachment of the electrode from the body However, there is a problem that during the treatment, the electrodes often interfere with the patient, resulting in an unnatural posture, and the effect is not always sufficient.
[0008]
The present invention has been made in order to solve the above-mentioned problems of the prior art, and is an inexpensive and simple device that enables a bather to obtain a warming effect, a blood circulation promoting effect, and a negative ion effect for a bathtub health promotion. It is an object to provide a device and a bathtub with a health promotion device.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a health promotion device for a bathtub and a bathtub with a health promotion device that can obtain a heat retaining effect, a blood circulation promoting effect, and a negative ion effect by the following means.
[0010]
That is, the health promotion device for a bathtub of the present invention provides an electrode provided in the bathtub, an independent power supply device of 12 V or less, and boosts the voltage of the power supply device in a voltage range lower than 35 V to supply power to the electrode. And a booster circuit.
[0011]
Said electrodes usually consist of a plurality of sets of individual electrodes which are sucked by suction cups provided on the mounting part on the inner surface of the bathtub at positions facing each other. Four of these electrodes are arranged on the inner surface of the four corners of the bathtub or on the inner surfaces of the left and right side walls at intervals in the longitudinal direction. A voltage is applied. In this case, the electrodes arranged in the same direction in the longitudinal direction have the same polarity. The number of electrodes is not limited to four, and the number can be increased or decreased according to the purpose. When the bathtub itself functions as a ground electrode, only one electrode may be provided in the bathtub. The electrode disposed in the bath tub is composed of an electrode body made of a conductive member and an electrically insulating holding portion attached to the electrode body in a watertight manner. The electrode body is watertight to the power supply lead wire in the holding portion. It is connected to the. It is desirable that the shape of the electrode main body be a curved surface whose exposed surface protrudes outward.
[0012]
Either a primary battery or a secondary battery can be used as the independent power supply device of the present invention. Specific examples include a dry battery, a nickel-cadmium battery, a nickel-hydrogen battery, a lithium battery, and a fuel cell. These are usually used at a voltage of 3 V or more and 12 V or less by connecting a plurality of them in series. In consideration of safety, the number of batteries connected in series is four (6 V or less), preferably three (4.5 V) in the case of dry batteries.
[0013]
Note that these power supply devices are used by being housed in a watertight housing provided with a suction cup and a hook portion, and disposed on a wall near the bathtub.
[0014]
The booster circuit of the present invention is a device that boosts the output voltage of an independent DC power supply to a voltage of 35 V or less, and may be a device equipped with a known inverter circuit. The voltage waveform from the booster may be any one of a pulse voltage, an AC voltage, and a pulsating voltage, and may be supplied with DC as needed. This booster circuit is also disposed in a watertight housing that houses the power supply device.
[0015]
Note that the housing is preferably provided with a power switch for intermittently supplying power to the electrodes provided in the bathtub, and a switch for changing the voltage applied to the electrodes in a plurality of stages in a stepwise manner. It is more preferable to provide a timer device capable of adjusting the voltage application time.
[0016]
ADVANTAGE OF THE INVENTION The health promotion apparatus for bathtubs of this invention can obtain a heat retention effect, a blood circulation promotion effect, and a negative ion effect with a cheap and simple apparatus.
[0017]
In addition, since the power supply device is an independent device of 12 V or less, the current that flows even when boosted by the booster circuit is extremely weak, so that there is no fear of electric leakage or electric shock even in a bathroom where the surroundings are in a humid or water atmosphere, You can take a bath with confidence.
[0018]
Further, if a timer device is provided and the voltage application time to the electrodes is set to about 15 minutes, for example, the power is automatically turned off even when the user falls asleep accidentally while taking a bath, which is safer.
[0019]

The size of each of the electrodes 4 to 7 may be different. Each of the electrodes 4 to 7 has a waterproof structure so that when provided in hot water, hot water does not enter into the container formed by the lower container 31, the lid 36, and the exposed electrode body 35.
[0030]
Next, the configuration of the control circuit 8 will be described with reference to FIGS. FIG. 6 is a circuit configuration diagram for explaining an embodiment of the control circuit 8. 7 is a front view of a container for protecting the control circuit 8 of FIG. 6 from water and moisture, and FIG. 8 is a rear view of a container that houses and fixes the control circuit of FIG. The same parts as those in FIGS. 1 to 5 are given the same reference numerals as in FIGS.
[0031]
The control circuit 8 includes a power supply device, for example, a computer such as a microcomputer 46 that operates using a dry battery 45 as a power supply, an oscillation circuit 47 and a booster circuit 48. The microcomputer 46 stores a predetermined output voltage of 35 V or less as an output voltage of the control circuit 8, and is programmed so that a bather can select a desired voltage. In this embodiment, a switch capable of selecting a continuous pulse voltage of 20 V or 30 V with a pulse width of 1 second as an output voltage of the control circuit 8 is provided. The output voltage of the control circuit 8 is not limited to 20 V and 30 V, and the microcomputer 46 can be programmed so that an output of 15 V, 10 V, or the like can be selected according to the use of a bather.
[0032]
Further, the microcomputer 46 controls the output voltage of the control circuit 8 to a voltage slightly higher than the set voltage of the bather during the period before bathing according to the use of the bather, and controls the output voltage of the bather to the set voltage at the time of bathing. Programs can also be stored. Further, the microcomputer 46 is programmed so that a bather can select a plurality of pulse widths, such as 1 second, 0.5 second, and 0.1 second, for the pulse width of the output voltage of the control circuit 8.

The output voltage waveform of the booster circuit 48 can be shaped into a desired waveform by a shaping circuit. For example, the rise time and fall time of a pulse may be shaped. The control circuit 8 is configured as described above. This control circuit 8 is formed on a printed circuit board.
[0035]
The control circuit 8 uses a dry cell 45 as a power supply device. In this embodiment of the dry cell 45, three 1.5V AA dry cells are connected in series to output a DC voltage of 4.5V. As the DC voltage, a voltage supplied for driving the microcomputer 46, the oscillation circuit 47, and the booster circuit 48 is selected. Therefore, the drive voltage of the microcomputer 46 is 12 V, 9 V, or the like depending on the other model name, and the voltage of the dry battery 45 is selected to be 12 V or less.
[0036]
For a control circuit 8 in a place where water splashes and is humid, such as a bathroom, a voltage of 12 V or less is desirable from the viewpoint of safety such as electric leakage and electric shock, and the use of the dry battery 45 requires the AC wiring work. No, it is suitable for use in bathrooms without AC outlets. In addition, they can be taken to hot springs and hotels for immediate use.
[0037]
Next, a container for accommodating the control circuit 8 having such a configuration will be described with reference to FIGS. A printed circuit board of the control circuit 8 shown in FIG. 6 is provided in a resin-made rectangular tubular container 51 having a bottom shown in FIG. A lid 52 made of resin is provided so as to fit in the container 51. In FIG. 7, the lid 52 has a downward slope 52a in FIG. 7 to form a curved surface. A female connector 53 to which the connector 21 shown in FIG. 2 is fitted is provided on the slope 52a in a liquid-tight manner. The female connector 53 is for outputting the output voltage of the control circuit 8 to each of the electrodes 4 to 7, and the female connectors 53 correspond to the electrodes 4 to 7 shown in FIG. 2 from the output circuit of the control circuit 8. It is attached and wired.
[0038]
The lid 52 is provided with a power switch 54 for controlling the opening and closing of the power supply of the control circuit 8. The power switch 54 is connected to the power supply of the control circuit 8. An open / close operation of the power switch 54 is connected to a circuit of the power switch 54 by a display lamp 55, for example, a light emitting diode so as to be visually confirmed. Further, the cover 52 is provided with a changeover switch 56 so that a bather can select a desired output. The changeover switch 56 is connected to an output circuit of the microcomputer 46 of the control circuit 8. The changeover switch 56 for switching the output of this embodiment switches between a high voltage, for example, 30 V, and a low voltage, for example, 20 V, and the display lamps 57, 58 are respectively set to the changeover switch 56 so that the bather can visually confirm the selected output. It is connected to a circuit and provided on the lid 52.
[0039]
Further, the lid 52 is provided with a display lamp 59 for notifying the bather of the time for replacing the dry battery. The power switch 54 and the changeover switch 56 are desirably constituted by a touch panel for use in a humid bathroom.
[0040]
On the back surface of the container 51, a dry cell installation section 61 for installing a dry cell 45, which is a power supply device of the control circuit 8, is provided. When the dry cell 45 is connected to the dry cell installation section 61, it does not come into direct contact with moisture. A lid 62 is provided, and the stopper 62 is used to lock the lid 62. The control circuit 8 is configured by fitting the lid 52 to the container 51 thus configured and fixing the lid 52 with, for example, a screw 60. The control circuit 8 is provided with two suction cups 64 and 65 and a hook 66 as means for detachably installing the control circuit 8 in the bathroom. Hooks 67, 68 for use when removing the suction cups 64, 65 are provided on the periphery of the suction cups 64, 65.
[0041]
Next, a method of bathing in the bath tub configured as described above will be described with reference to FIGS. The bather supplies hot water for bathing to the bathtub 2. Subsequently, the bather adsorbs and fixes the electrodes 4 to 7 shown in FIG. 2 to the inner wall surface of the bathtub 2 as shown in FIG. The electrodes 4 to 7 are desirably provided so that the whole is located in the hot water. When a weak current is applied to the legs or the feet, it is desirable that the electrodes 4 to 7 be installed at the bottom or at a position close to the bottom.
[0042]
The control circuit 8 is mounted on, for example, an inner wall surface of the bathroom by suction with suction cups 64 and 65, for example. The connectors 21 of the electrodes 4 to 7 shown in FIG. 2 are fitted and connected to the female connector 53 shown in FIG. When the power is turned on by controlling the power switch 54 to ON, the control circuit 8 starts operating, and the display lamp 55 is turned on. Thereafter, a small current starts flowing between the electrodes 4 and 5 and between the electrodes 6 and 7. In this state, when a minute current is continuously supplied for 10 minutes, the hot and cold water in the bathtub 2 becomes mellow hot and cold water.
[0043]
After continuing to supply the minute current for 10 minutes, the bather enters the bathtub 2 and starts bathing with the minute current kept flowing. In the bathtub health promotion device 3, a protection program is input to the microcomputer 46 in advance so as to be automatically turned off in 15 minutes. Therefore, the bather receives a weak current by bathing in a state where a voltage of 30 V or 20 V is applied for 5 minutes. In this example of the weak current, the weak current flowing in the hot and cold water was 10.9 μA at the voltage between the electrodes of 20 V, and the weak current flowing in the hot water and the cold current of 11.5 μA at the voltage between the electrodes of 30 V. This weak current also flows to the bather.
[0044]
In this way, when the bather takes a weak current for only 5 minutes, the bather greatly improves the heat retaining effect, has a cell cleaning effect while bathing, and can obtain a blood circulation promoting effect. These bathing effects vary from person to person, and if the sensitivity is too good, the intensity needs to be adjusted. For example, for some people, the blood circulation condition of the feet has been significantly improved, and even after 1 hour from bathing, there is still a warming effect, and the warming effect has been improved for 30 minutes or more. It is considered that the blood circulation promoting effect is that the weak current flows through the living body of the bather to make the hot water mellow, thereby improving the blood circulation of the whole body. Furthermore, according to the experiment of the inventor, new metabolism is activated. Bathing in hot and cold water flowing a weak current is effective in recovering fatigue because the whole body is gently massaged.
[0045]
In addition, a result of examining the effect that the hot and cold water has a mellow effect will be described. By applying a weak current to hot water using the bathtub health promotion device 3, it was found that the small group of water molecules was small as shown in FIG. Next, this phenomenon will be specifically described with reference to FIG.
[0046]
FIG. 9 is an absorption curve diagram in which the vertical axis represents the amount of electromagnetic wave absorption in hot and cold water, the horizontal axis represents the sweep frequency of the electromagnetic wave, and the resonance frequency is shown as zero. That is, FIG. 9 shows the frequency of the electromagnetic wave transmitted through the hot water and the isotope contained in the hot water. ¹⁷ FIG. 4 is an NMR spectrum obtained by measuring the absorption at O, showing an absorption curve centered on a resonance frequency of 0. The solid line indicates an absorption spectrum when a weak current is passed through the bath water at 25 ° C. by the bathtub health promotion device 3, and the dotted line indicates an absorption spectrum at 25 ° C. when the weak current is not passed. That is, in FIG. 9, the half-width of the absorption spectrum when a weak current is passed is 103 Hz, and the half-width of the hot water absorption spectrum when a weak current is not passed is 73 Hz. From this, it is expected that the hot water flowing the weak current has a small group of water molecules. The smaller the small group of water molecules, the greater the effect of activating new metabolism. In addition, the smaller the cluster, the smoother the skin becomes.
[0047]
Further, the bathtub health promotion device 3 has an effect of generating a large amount of negative ions from the surface of the hot water when the switch is turned on and a weak current flows in the hot water. An example of the amount of the generated negative ions was as shown in FIG. That is, FIG. 10 is a characteristic curve diagram when the horizontal axis indicates time and the vertical axis indicates the measured amount of negative ions.
[0048]
The characteristic in FIG. 10 is data obtained by filling the bathtub 2 with 40 ° C. hot water and measuring the amount of negative ions above the hot water surface using an ion tester KST-900 manufactured by Kobe Denpasha Co., Ltd. as a negative ion measuring device. . For 15 seconds when the switch of the bathtub health promotion device 3 is OFF, the measured amount of negative ions in the bathroom is 50 / cc or less, and after 15 seconds, the negative pressure is measured by a sensor installed in the bathtub 2 near the surface of 40 ° C. The measured amount of ions increases after the switch of the bathtub health promotion device 3 is turned on, and after 5 seconds, shows a saturation characteristic, and 125 to 140 negative ions are generated. When the switch of the bathtub health promotion device 3 was turned off after 65 seconds after the switch of the bathtub health promotion device 3 was turned on for 50 seconds, a state in which negative ions were generated was shown in FIG. 9 for 5 seconds. I have. Therefore, the bather can take this negative ion at the same time.
[0049]
When the switch of the bathtub health promotion device 3 is in the OFF state, the amount of negative ions indicated by the sensor on the surface of the 40 ° C. hot water filled in the bathtub 2 is indicated by a dotted line in FIG. That is, 70 to 90 negative ions / cc are generated on the surface of the hot and cold water at 40 ° C. From these results, the characteristic curve diagram of FIG. 10 shows that when the switch of the bathtub health promotion device 3 is turned on, the amount of negative ions significantly increases. That is, FIG. 10 shows that the amount of negative ions increases when a weak current is passed through hot water at 40 ° C. by the bathtub health promotion device 3.
[0050]

However, one set of two electrodes 4 and 5 or 6 and 7 may be used, or one electrode as shown in FIG. By providing one sheet 71 and arranging a plurality of electrodes 72, 73, 74 at opposing positions, a weak current may be diffused. Further, by arranging the electrode arrangements as shown in FIG. 11 in mutually opposite directions as shown in FIG. 12, the weak current can be further diffused, so that more bathers can take a bath at the same time.
[0051]
In the above embodiment, the embodiment in which the pair of electrodes facing each other is provided on the side wall surface of the bathtub 2 has been described. However, the electrodes may be provided on the bottom surface of the bathtub or the body of the bather 81 as shown in FIG. May be provided. That is, for example, the electrodes 4 and 5 or 6 and 7 opposed to the back 82 and the foot 83, which are located in the bath water of the bather 81, respectively, are provided by contacting or applying cream to the body surface. May be flowed. Also in this embodiment, since a weak current can be applied to the body of the bather 81, the same effect as in the above embodiment can be obtained.
[0052]
In addition, the independent power supply means a power supply that does not use an AC power supply when the bathtub health promotion device operates. As the independent power supply device, any of a primary battery and a secondary battery can be used, and specific examples thereof include a dry battery, a nickel-cadmium battery, a nickel-hydrogen battery, a lithium battery, and a fuel cell.
[0053]

When a DC voltage is supplied to the opposing electrodes, for example, the electrodes 4 and 5, the negative electrode is grounded and the bathtub 2 is grounded as shown in FIG. May be installed at a desired position. In this embodiment, the same effect as in the above embodiment can be obtained.
[0054]

In the above embodiment, the example in which the electrode pieces 32 of each of the electrodes 4 to 7 and the relay conductor 33 are provided in a liquid-tight container has been described. However, if it can be processed so as not to damage the bather's skin. Alternatively, the cables 11 to 13 may be connected directly to the exposed electrode body 35.
