[0002]

2. Description of the Related Art Gas bath devices of ozone, hydrogen or the like are known for the treatment or hygiene of special parts of the body, but these are installed in hospitals and medical facilities.
It is difficult to use at home. Moreover, the existence of a foot-only ozone bath device that has a built-in ozone generator and can be used in ordinary households cannot be recognized. Various products for foot sole stimulators or foot warmers are commercially available, but none of them have a function of generating ozone gas and performing deodorant sterilization.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is to solve the problem that a deodorant sterilizer with a built-in ozone generator that can be used in ordinary households and that combines hygiene and athlete's foot treatment is simple and convenient. To provide a footrest. Still another object of the present invention is to provide a deodorizing and sterilizing foot stand with a built-in multi-purpose ozone generator that also serves as a health device or a foot warmer that stimulates acupoints on the soles of the feet.

[0004]

[Means for Solving the Problems] In order to solve the above problems,
The main body of the footrest is connected to the front of the pedestal for footrest, straddling the left and right ends and the front end of the pedestal, and connected to the peripheral edge of the pedestal so as to form a space into which the toes can be inserted from the rear. A cover portion is formed, and a peripheral edge portion that rises upward is formed over the entire circumference at the peripheral edge of the pedestal behind the cover portion.

A partition section is formed above the inside of the cover section by a partition member having one or more vent holes communicating with the toe insertion space, and an ozone generator and its control are provided in the section. In addition to accommodating the means, a foot detection means for detecting the presence or absence of foot insertion is provided at an appropriate place inside the footrest base body, and when the foot is inserted into the footrest base body, the foot detection means is detected to control the control means. Operates the ozone generator so that the generated ozone flows into the space and the entire upper surface of the pedestal through the vent hole.

In the above, there are various ozone generators, but it is convenient to use an ultraviolet lamp which is inexpensive and easy to handle.

As the control means of the ozone generating device, the control circuit of the ozone generating device, the foot detecting means, and a circuit opening / closing circuit which operates in a chained manner with the foot detecting means to open / close a power supply circuit to the control circuit. And means.
Further, the control circuit is provided with a timed operation means for stopping the operation of the ozone generator when the foot is removed from the footrest main body and for operating the ozone generator for a predetermined time when the foot is inserted.

The foot detecting means includes an optical sensor, a proximity switch for detecting magnetic disturbance, or an appropriate mechanical interlocking mechanism that operates when the foot is inserted into a pedestal and a mechanical limit switch that contacts the movable portion. Etc. may be used, and this may be used in combination with a relay or the like so that the power supply circuit can be opened and closed. Further, the timed operation mechanism may be of a system in which a circuit using a timer or the like is interposed, and may be constituted by a relay for turning on / off a power supply to a control circuit of an ozone generator such as an ultraviolet lamp.

It is convenient to provide an operation display means of the ozone generator outside the main body of the footrest. A LED lamp (light emitting diode) is used for this operation display means, and it is optimal for a small and smart appearance. However, a small window in which a milky white acrylic plate or frosted glass is attached is formed in the cover portion covering the ultraviolet lamp. Then, the operation of the ultraviolet lamp can be confirmed through this small window.

The footrest insertion opening at the rear end of the cover portion of the footrest base body is provided with a flexible hanging curtain member that hangs down from the rear end of the covering portion, and the hanging curtain member allows ozone in the internal space to travel along the instep of the foot. This is convenient because it is possible to limit the escape to the outside and enhance the effect of the ozone bath.

Further, when a large number of wart-like projections are formed on the upper surface of the inside of the pedestal of the main body of the footrest, or a streak-like ventilation groove is formed along the surface, the ozone gas causes a gap between the wart-like projections and a ventilation groove. It spreads through the pedestal and effectively acts on the sole of the foot. Furthermore, it is preferable that the tip end surface of this wart-like projection group and the upper surface of the pedestal forming the ventilation groove are formed in a wavy shape because the unevenness of the upper surface also serves as a health device that stimulates the acupoints on the soles of the feet. Therefore, the ventilation grooves are formed in a large number not only in the front-back direction of the pedestal but also in the direction intersecting with the pedestal.
It is preferable that the tip of the projection group and the upper surface of the pedestal in which the ventilation groove is formed have a wavy shape as a whole.

On the other hand, the main body of the footrest is divided into an upper part including a partition for accommodating an ozone generator and a lower part other than the partition part, and both of them are detachably fitted or mounted. The two parts are connected via a separable hinge so that the upper part can be flipped up and detached. With such a structure, it is convenient to remove the lower part for cleaning, or in the case of a structure in which the both parts are connected via a hinge, the upper part can be flipped up and the foot can be easily taken in and out, which is more preferable. .

Further, if a heater is attached to the bottom surface of the pedestal of the footrest, it can be conveniently used as a deodorizing and sterilizing footrest that also serves as a foot warmer.

A control circuit for supplying power to 2 is formed.

Next, a more detailed structure of the above-mentioned deodorizing and sterilizing footrest 1 will be sequentially described. The footrest base body 2 forms a space in which an upper portion is covered with a cover portion 4 and an opening 7 is formed in the rear in front of a pedestal 2a which is large enough to support both feet and has a substantially rectangular plane, and at the rear of the pedestal 2a. Is surrounded by a peripheral member 3 having a short height, and is formed in a groove shape. More specifically, the footrest main body 2 is provided with supporting members 2c, 2c on the bottom surface and a substantially rectangular member having a large number of wart-like projections formed on the upper surface 2b. Rising edge 3
The left and right members 3a and 3b of the peripheral portion 3 have a rear portion having a short height and a rear portion having a high height near the center, and a front portion thereof having a mountain-shaped middle height shape, and a rear end member 3c. Is the same height as the rear ends of the left and right members 3a, 3b, and the front end member 3d is the same height as the front ends of the left and right members 3a, 3b, and they are integrally formed so as to surround the periphery of the pedestal 2a. In the chevron part, the member 3a,
This is a structure in which a cover portion 4 connected to the tops of 3b and 3d is integrally formed.

Next, the detailed structure of the ozone generator 5 will be described. The ozone generator 5 is housed in a substantially horizontal partition section 6 formed by attaching a partition member 8 above the inner space of the cover 4. The partition section 6 is divided into two sections in the front and rear by another vertical partition member 11 fixed to the partition member 8 and the rear partition section 6a (see FIG. 2).
Has a plurality of vent holes 9 penetrating to the space 10 at the rear side and communicating with the space 10 below the cover part. The partition members 8 and 11 are molded from an appropriate member such as steel or aluminum that withstands ultraviolet rays and ozone, and the partition member 11 has screw holes 15 and 15 (see FIG. 2) and attach and fix it to the upper part of the cover part 4.

An ultraviolet lamp 12 for ozone generation is attached directly above the vent 9 of the rear partition section 6a, while a control board 13 for the ultraviolet lamp 12 is housed in the front partition section 6b, and the aforementioned ultraviolet lamp 12 is installed. The proximity switch 20 and the operation indicator lamp 21 to the lead wires 12a, 20a, 2
Each of them is connected to the control board 13 via 1a. In addition,
The control board 13 is provided with screws 16 in front of the vertical partition member 11,
16 is attached and fixed, and is protected from the ultraviolet rays of the ultraviolet lamp 12 by the vertical partition member 11. On the other hand, although not shown, the control board 13 is connected with a power cord having an outlet plug at the tip. . The ozone generator has the above configuration.

On the other hand, although not shown, it is convenient to additionally install a light shielding plate between the ultraviolet lamp 12 and the vent hole 9 in addition to the configuration of the ozone generator described above, and a spacer is provided directly above the vent hole 9. For example, a band-shaped light-shielding plate may be attached with a screw so that it is separated from the vent hole 9 by an appropriate distance. The light-shielding plate is intended to prevent ultraviolet rays from directly irradiating the foot inserted into the footrest via the ventilation hole 9, and does not hinder the generation of ozone in the vicinity of the ultraviolet ray lamp 12 and moves toward the space 10 side. Any form may be used as long as it does not hinder the inflow of ozone.

Further, the proximity switch 20 mounted in front of the partition member 8 uses a commercially available product of a type in which a detection signal is emitted due to the disturbance of the magnetic force which occurs when a person's foot is approached. Alternatively, a photoelectric switch may be used, or a mechanical limit switch that operates via an appropriate lever mechanism that interlocks with the insertion of the foot may be used.

An LED is used as the operation display means of the ozone generator.
Although the lamp 21 is used, it may be replaced with an appropriate one such as an incandescent lamp, or in addition to the LED lamp and the like, a small window in which a milky white acrylic plate or a frosted glass plate is attached to the cover portion 4 of the ultraviolet lamp 12 is provided. Alternatively, the operation may be confirmed by blue light shining through the small window when the ultraviolet lamp 12 is turned on.

At the rear end 7a of the cover portion 4, it is preferable to attach a flexible hanging curtain member 17 for partially partitioning the opening portion 7. In order to limit the free leakage of ozone from the front space 10 and to spread it over the entire upper surface 2b of the pedestal 2a so that the entire sole of the foot placed on the pedestal is immersed in ozone. It is provided as an effective means. The hanging curtain member 17 is formed in a curtain shape or a goodwill shape by using a sheet-shaped or string-shaped material or the like, and it is possible to easily insert and pull out the toes in the space 10 and the space 1
The ozone gas in 0 may be structured so as to be restricted from freely flowing out through the instep of the foot F.

Next, a large number of wart-like projections 18 are provided over the entire surface of the upper surface 2b of the pedestal 2a. Due to the existence of the wart-like projections 18, the UV lamps 12 generate the light in the space 10. This has the effect of helping the inflowing ozone gas to spread over the entire upper surface 2b of the pedestal through the gap between the protrusions 18. As an alternative to the wart-shaped protrusion 18, although not shown, a ventilation groove may be formed on the upper surface 2b of the pedestal 2a. In that case, it is effective that the ventilation groove is configured by a large number of grooves running in the vertical and horizontal directions by combining a groove formed in the front-rear direction of the pedestal 2a and a groove formed in a direction intersecting with the groove.

Although not shown, the upper surface of the wart-like protrusion 18 or the ventilation groove (not shown) is curved or corrugated in accordance with the shape of the sole such as the arch of a foot as a health device for the foot. Then, it can be used also as a health device that stimulates the acupoints on the soles of the feet, which is preferable. In addition to the above-described components, the deodorizing and sterilizing footrest base 1 includes a footrest base body 2
When an appropriate electric heater (not shown) is attached to the bottom of the pedestal 2a, for example, inside or on the back surface, it can be used as a foot warmer in addition to deodorant sterilization, and can be used for more versatile purposes.

Various embodiments are conceivable as the control device for the ultraviolet lamp 12, and the basic circuit configuration thereof is schematically shown in FIG. The control circuit 30 of the ultraviolet lamp 12 includes an AC power supply 31, a power supply ON / OFF switch 32 (SW) connected to the AC power supply 31, and a rectification connected to the power ON / OFF switch 31 (SW) sequentially from the left side of the drawing. Circuit 33
And a circuit opening / closing means 34 including the proximity switch LS (corresponding to the reference numeral 20) connected to the rectifier circuit 33, the relay X connected thereto and the contact X1 of the relay X for opening and closing the power supply to the control circuit, and a circuit. A timer T connected to the rear of the opening / closing means 34 and a timer operating contact T1 thereof, a time-varying circuit 35 connected in parallel to the ultraviolet lamp UV (corresponding to the reference numeral 12) and the operation display. Lamp RL (corresponding to the reference numeral 21)
Are connected as shown in the figure. Although not shown, the timed operation circuit 35 and the ultraviolet lamp UV.
An inverter circuit as an ultraviolet lamp control circuit similar to the control circuit of a general discharge tube lamp is interposed between (reference numeral 12).

The control circuit 3 is provided on the control board 13 described above.
The components other than the ultraviolet lamp UV (12), the operation indicator lamp RL (21), and the proximity switch LS (20) among the components of 0 are incorporated.

With respect to the ultraviolet lamp UV (12), it is possible to select an appropriate output depending on the size of the footrest base body 2 and attach it. In the illustrated embodiment, the output of the ultraviolet lamp is 4 W (watt), but it is also possible to use a lamp of other output depending on the size of the footrest, and the electric capacity of the components of the control board 13 is used. If it is designed according to the maximum output of the UV lamp to be used, it can be appropriately used within that range.

Although the operating time of the timer T can be arbitrarily set, about 10 minutes is usually appropriate in consideration of the time interval for putting in and out of the foot. In the illustrated timer T, when the timer T is energized, the timer contact T1 is turned ON, that is, the circuit is closed, and after 10 minutes of the set time, the timer contact T1 is turned on.
Is OFF, that is, the circuit opens, and the proximity switch L
A timer of a type is used in which the initial state, that is, the timer contact T1 returns to OFF when the energization is stopped by S or the like. Further, the power on / off switch SW is turned on at the beginning of the installation, and thereafter the on / off operation of the switch is unnecessary except for maintenance.

Next, the operation of the deodorizing and sterilizing footrest 1 having the above structure will be described. First, since the power on / off switch SW is turned on in advance as described above, the proximity switch LS (20) is turned off correspondingly before the foot F is inserted, and the relay connected to this switch is turned on. When X is de-excited, the relay contact X1 is turned off, the power control circuits of the ultraviolet lamp UV (12) and the operation indicator lamp RL (21) are cut off to turn them off, and the timer T is also turned off. Have been initialized (that is, the timer contact T1 is OFF). At this time, when the foot F is inserted from the opening 7 into the space 10 of the deodorization sterilization footrest 1 and placed on the upper surface 2b of the pedestal, the proximity switch L is correspondingly correspondingly placed.
When S (20) is turned on and the relay X connected thereto is excited to turn on its relay contact X1, the timer T is energized and at the same time the timer contact T1 is turned on. Operation indicator RL (2
1) turns on.

After that, when the timer T is left for about 10 minutes, the timer T turns off the timer contact T1, so that the ultraviolet lamp UV (12) and the operation indicator RL (21) are automatically operated even when the foot is inserted. It goes off, but if
If the foot is pulled out before the set time of the timer T elapses, the proximity switch LS (20) is correspondingly turned off.
Then, the contact X1 cuts off the power source, so that the ultraviolet lamp and the operation indicator lamp are automatically turned off and the timer is initialized at the same time as the removal of the foot, as described above.

In the above, while the ultraviolet lamp 12 is in the lighting operation, oxygen molecules contained in the air around the ultraviolet lamp 12 receive ultraviolet energy and are converted into ozone molecules through a known reaction. Since the ozone molecules generated in this way have a higher specific gravity than air, they pass through the vent holes 9 of the partition section 6a, flow into the front space 10 inside the footrest base below and gradually settle, and then inside the space 10 and the warts 18. Ozone gas spreads and fills the inside of the peripheral edge portion 3 surrounding the periphery of the pedestal 2a, that is, the entire upper surface 2b of the pedestal, through the gap or the ventilation groove (not shown). As a result, the ozone concentration in the space 10 and the upper surface 2b of the pedestal 2a gradually rises when the ultraviolet lamp is turned on, and the concentration is sufficient for deodorization and sterilization within about 10 minutes (about 0.4 to 0.
(5 ppm), the odorous components adhering to the inserted foot and the bacteria and athlete's foot affected parts are acted on to decompose and deodorize and sterilize them.

Next, another embodiment of the present invention is shown in FIGS. 5 and 6, and this embodiment will be described. In addition, FIG. 5 shows the deodorizing sterilization footrest according to the present invention.

It is formed so as to overlap the top portion of the front end member 43d to be connected. As a result, the cover portion 4
In the state where 4 is superposed on the lower portion 41b, the space 10 having the rear opening 46 into which the tip of the foot can be inserted is formed below the cover portion 44 as in the case of FIG.

In the vicinity of the lower end of the cover portion 44, a partition member 6 having a large number of vent holes 9 having the same structure as that of FIG. Another vertical partition member fixed to the partition member 8 partitions the partition section 6 into two sections, the front partition section 6 and the front partition section 6.
The ozone generator 5 is configured by accommodating the ultraviolet lamp 12 in a and the control board 13 in the front partition section 6b.

Also in this case, as in FIG. 1, the proximity switch 20 is installed in the partition member 8 of the front partition section 6b toward the lower space 10, and the ozone generator 5 is installed at the center of the upper portion of the cover portion 44. LED lamp 21 for operation display
These devices and the ultraviolet lamp 12 are connected to the control board 13 by lead wires (not shown). In addition, the opening 46 is provided with a flexible drape-shaped member 47 that hangs down from the rear end of the cover portion 44, thereby restricting free leakage of ozone gas from the internal space 10 along the instep of the foot F inserted in the opening 46. ing.

The front end member 43 of the lower portion 41b of the footrest base body 41 and the front end of the upper portion 41a are connected by a hinge mechanism 45, and the upper portion 41a, that is, the rear of the cover portion 44 is configured to be able to flip up to the upper portion. There is. And the hinge mechanism 45
Although the detailed structure is not shown, the upper and lower hinge members have a structure in which they can be separated at the rotation center pin. However, instead of this structure, one of the upper and lower hinge members may be detachably attached to the footrest base body 41.

The lower part 41b can be separated into the lower part 41b and the lower part 41b when the footrest is dirty.
It has a convenient structure that can be washed.

The operation of the ozone generator 5 of the deodorization sterilization footrest 40 and its control circuit is exactly the same as in the case of the deodorization sterilization footrest 1 described above, and a duplicate description will be omitted.

In order to confirm the deodorizing effect of the ozone generator used in the deodorizing sterilization footrest according to the present invention, a sensitivity test was conducted using an experimental apparatus. The experimental device has a structure in which an ozone generator consisting of a UV lamp with an output of 4 W is mounted on a cubic storage box with a side of about 40 cm, and the ozone generated by turning on the UV lamp flows into the storage box. It is a device. The experiment uses one of the socks worn by 10 people for the test piece, confirms the odor and moisture condition to each person in advance, stores it in the experimental device, lights the ultraviolet lamp for 10 minutes, After the ultraviolet lamp was turned off, the sample was left for 10 minutes and then taken out, and each person was asked to compare the test results with the non-test products, and the results were recorded. Table 1 shows the results of the sensitivity test.

[0042]

[Table 1]

As is obvious from Table 1, the deodorizing effect is remarkably shown, and it is replied that all 10 test pieces had no odor. At this time, the ozone concentration in the storage after turning on the ultraviolet lamp for 10 minutes was estimated to be about 0.496 ppm or more from the time-concentration measurement data separately measured (see Table 3), and a sufficient bactericidal effect was also obtained. On the other hand, it is expected that ozone of this concentration will be decomposed to 0.1 ppm or less, which is the safety standard value set by Japan, in about 20 minutes, according to another data (not shown). Therefore, there is no problem in practical use without considering the size and ventilation of a room in which the deodorizing and sterilizing footrest of the present invention is used.

Next, in order to confirm the relationship between the sterilizing effect of ozone and the ozone concentration, an experiment was conducted using another experimental apparatus. The experimental device for the sterilization effect confirmation experiment has a width of 90
A device with a structure in which an ozone generator consisting of an ultraviolet lamp with an output of 4 W is mounted on a storage box with a door of 0 mm, depth 515 mm, and height 1790 mm, and ozone generated by turning on the ultraviolet lamp flows into the storage box. The storage box is closed except for the ozone inlet.
The sterilization effect experiment was carried out by storing a petri dish containing a 5 cm square cloth to which about 20,000 Staphylococcus aureus was adhered, with the lid opened at the bottom of the experimental apparatus, and the time conditions shown in Table 2. Turns on the ultraviolet lamp (that is, activates the ozone generator)
Immediately after that, the lid of the petri dish was closed, and then the petri dish was transferred into a safety cabinet, 20 ml of SCD agar medium was poured thereinto, and this was cultured at 37 ° C. for 24 hours, and the number of bacteria was examined. Regarding the relationship between the time lapse of the experimental device and the ozone concentration, the same device as in the experiment of sterilization effect was used, the door was opened and the inside was sufficiently ventilated with natural air,
After closing the rear door and turning on the ultraviolet lamp for a predetermined time, the air inside was sampled to measure the ozone concentration. Table 2 shows the experimental results of the bactericidal effect, and Table 3 shows the experimental results of time-ozone concentration.

[0045]

[Table 2]

[0046]

[Table 3]

As is obvious from Table 2, the ozone generator operates for about 10 minutes and the number of Staphylococcus aureus colonies is 1/1.
When the ozone generator is operated for 15 minutes and left in the environment for 15 minutes, the number of colonies becomes zero, which is a dramatic effect. On the other hand, according to Table 3, when the ozone generator operating time is 10 minutes and 15 minutes, the ozone concentration is 0.496 ppm and 0.
It shows that it reaches 736 ppm, and that a sufficient bactericidal effect can be expected even at such a concentration. Also,
The residual ozone after stopping the operation of the ozone generator decomposes and disappears in a relatively short time in the experiment conducted together with the above experiment, and the ozone concentration of 0.4 to 0.5 ppm is 0.1 ppm of the safety standard of Japan. It was also confirmed that the remaining ozone concentration was about 20 minutes (data not shown) until it became below, and the residual ozone concentration was about 1/10 in about 30 minutes, and about 1/100 in about 60 minutes. The effect of residual ozone is negligible.

[0048]

EFFECTS OF THE INVENTION The deodorizing and sterilizing footrest according to the present invention enables the ozone concentration in the footrest to be adjusted to a concentration sufficiently effective for deodorizing and sterilization by simply turning on the ultraviolet lamp for about 10 minutes. Moreover, since ozone has the property of being able to sufficiently sterilize and deodorize even in a short time, it is possible to deodorize and sterilize at a low power cost.

Further, the output can be changed only by exchanging the ultraviolet lamp within a range not exceeding the allowable output on the design of the control board, and when combined with the adjustment of the timer, the common control parts can be used for the purpose. It is possible to manufacture products with different outputs and different operating times at a low price.

According to the present invention, it can be used not only as an ozone bath device for deodorizing and sterilizing feet and for treating affected areas such as athlete's foot, but also as a health device for stimulating acupoints on the sole of the foot or a foot warmer. It is possible to provide a versatile footrest that can be easily used in ordinary households.

In the deodorizing and sterilizing footrest according to the present invention, the ozone generator is covered with the front cover portion and the rear opening of the cover portion is partitioned with the flexible flap member so that ozone does not freely leak to the outside. . Then, the control means of the ozone generator automatically stops the ozone generator (that is, turns off the ultraviolet lamp) at the same time when the foot is pulled out, starts the ozone generator at the same time when the foot is inserted, and starts the ozone generator for a predetermined time (about 10 minutes). Since it is configured to automatically stop after a lapse of time, the generation of excess ozone in excess of the necessary amount is prevented, and the ozone concentration is low, so it spontaneously decomposes and disappears in a short time and falls to a safe concentration. From the above, the deodorant sterilization footrest according to the present invention is highly safe and can be safely used even by a person without special knowledge.
