Description

[Detailed description of the invention] [Field of industrial application] This invention prevents the proliferation of bacteria and the generation of strange odors by injecting ozone into the water in the bathtub (in this invention, water is also referred to as water). , relates to a bathtub that also has health-promoting effects.

[Prior art and its problems] Conventionally, as a method for purifying hot water in a bathtub, hot water in a bathtub is circulated and passed through a filter.
Methods for removing impurities are known. However, since the dissolved organic matter and bacteria cannot be removed by purification using a filter, there are problems such as a foul odor generated due to changes in the organic matter and undesirable hygiene. Therefore, in the past, hot water had to be replaced frequently.

Chlorine sterilization is known as a method to solve hygiene problems, but in this case, toxic chlorine gas must be stored, the hot water has an unpleasant chlorine odor, and it is carcinogenic. There are problems such as the generation of organic chlorine compounds (trihalomethanes), so it cannot be applied to purify hot water in bathtubs.

[Means for Solving the Problems] The present invention provides a bathtub having a system for supplying fresh hot water or circulating hot water to the bathtub, in which a gas-liquid mixer is provided in the middle of the system, and a gas-liquid mixer is provided downstream of the gas-liquid mixer. A gas-liquid separator is installed on the side, an ozone generator is connected to the gas-liquid mixer, and an ozone decomposer is provided into which the ozone separated by the gas-liquid separator is introduced.

[Function] In the ozone-injected bathtub of the present invention, since ozone is injected into the water in the bathtub, the water in the bathtub has effects such as sterilization, anti-mold, and decomposition of organic matter, and ozone also has a pine surge effect. be done.

In the present invention, after ozone gas is dissolved in hot water in a gas-liquid mixer, undissolved ozone gas is separated from the hot water in a gas-liquid separator. Since only dissolved ozone is supplied to the bathtub, no ozone gas is introduced into the bathroom. On the other hand, since the ozone gas separated by the gas-liquid separator is decomposed into harmless oxygen in the decomposer, the environment around the bathroom is also maintained in a good condition.

[Example] Examples will be described below with reference to the drawings.

FIG. 1 is a system diagram showing the configuration of an ozone injection bath according to an embodiment of the present invention. Reference numeral 1 indicates a bathtub body, and a circulation line 3 for circulating water 2 therein is provided. A filter 4, a pump 5, and an ozone dissolving device 6 are provided in the middle of the circulation line 3. Reference numeral 7 denotes an ozone generator for supplying ozone to the melting device 6.

In this embodiment, the ozone generator 7 includes an oxygen cylinder 8, a flowmeter 9 for measuring the flow rate of oxygen gas from the oxygen cylinder 8, and an ozone generator 10 for ozonizing the oxygen supplied through the flowmeter 9.
It is equipped with

The dissolving device 6 also includes a gas-liquid mixer 11 that receives water from the pump 5 and a gas-liquid separator 12 that receives water from the gas-liquid mixer 11. In addition to the water from the pump 5, gas containing ozone from the ozone generator 10 is introduced into the gas-liquid mixer 11, and ozone is dissolved in the water flowing through the circulation line 3. As this gas-liquid mixer 11, a line mixer or the like is suitable.

An ozone decomposer 13 is connected to the gas-liquid separator 12 for decomposing ozone contained in the separated gas.

In the ozone injection bath having such a configuration, a portion of the oxygen gas supplied little by little from the cylinder 8 is converted into ozone by the ozone generator 10, and introduced into the gas-liquid mixer 11 together with the oxygen gas.

On the other hand, water in the bathtub body 1 is sucked into the pump 5 through the filter 4, ozone is dissolved in the gas-liquid mixer 11, and then subjected to gas-liquid separation processing in the gas-liquid separator 12. It is returned to 1. In the gas-liquid mixer 11, oxygen gas containing ozone is vigorously mixed with water, and a portion of the ozone is dissolved. Undissolved gas is separated by a gas-liquid separator 12 and discharged into the atmosphere through an ozone decomposer 13. In this invention, the bathtub 1 is only heated when ozone is dissolved in hot water.
ozone gas is not introduced into the bathroom. Therefore, there is no possibility that bathroom users will inhale ozone gas or that ozone gas will irritate the bathroom users' eyes. Therefore,
A comfortable bath is possible. Further, since ozone gas that is not dissolved in the hot water is decomposed into harmless oxygen in the ozone decomposer 13, the environment around the bathroom is also good.

In such an ozone injection bathtub, the bathtub 1
Ozone comes to be dissolved in the water 2 inside, and effects such as sterilization and mold prevention are exerted. That is, ozone has a high oxidizing ability, and even in a small amount, it has a high effect of sterilizing various bacteria and preventing the growth of molds such as Candida. According to the inventor's various research results, 37 containing 0.1 ppm ozone
Escherichia coli is sterilized in about 0.5 seconds in warm water at ℃.
In addition, the effect of preventing the proliferation of molds such as Candida, detoxification of viruses, and complete oxidation of guanic acid in nucleic acids was observed.

In addition, ozone has good biodegradability and quickly decomposes organic matter dissolved in the water in the bathtub, producing products that are easy to clean up and clean up. and,
Due to these effects such as sterilization, anti-mold, and decomposition of organic matter,
The generation of strange odors is also prevented.

The solubility of ozone in water is approximately 10% that of oxygen.
It dissolves quickly, about twice as much. Dissolved ozone has a short half-life, decomposing in about 30 minutes and returning to harmless oxygen, so there is no need to worry about over-treatment.

Also, when warm water containing a small amount of ozone comes into contact with the skin, it has the same effect on improving blood circulation as pine surge.

In the device of the above embodiment, the oxygen sent from the oxygen cylinder 8 is ozonated by the ozone generator 10, but by adjusting the output of the ozone generator 10, the amount and concentration of ozone generated can be controlled by circulating. It can be adjusted freely according to the amount of water, etc.

FIG. 2 is a system diagram showing the structure of an ozone injection bath according to a different embodiment of the present invention. In the embodiment bathtub of FIG. 2, a water heater 14 for supplying fresh hot water to the circulation line 3 is provided.
That is, in the bathtub shown in FIG. 1, ozone could not be injected unless the water 2 in the bathtub body 1 was circulated through the circulation line 3, but in the embodiment shown in FIG. Ozone can be dissolved in the hot water supplied to the bathtub body 1 in a gas-liquid mixer 11 and then supplied to the bathtub body 1. Therefore, ozone-containing hot water can be supplied into the bathtub body 1 even when the circulation line 3 is stopped. Note that the reference numeral 15 in FIG. 2 indicates a flow path switching valve.

In addition, in this invention, without providing the circulation line 3,
A configuration may also be adopted in which ozone is dissolved only in the hot water supplied from the water heater 14 or the like.

In the above embodiment, an oxygen cylinder is used as the oxygen source, but a dry air supply device such as a combination of an air compressor and a dehumidifier may be used instead of the oxygen cylinder.

Further, when constructing the ozone injection bath as described above, it is preferable that the members that come into contact with the ozone-containing water be constructed of a material that is resistant to ozone. Examples of such materials include stainless steel, aluminum, vinyl chloride, nylon, Teflon, and Viton (trade name), but other ozone-resistant materials may also be used.

In addition, using an ozone generator with an ozonation rate of 2.25%, 1mg/hour is applied to the bathtub body with a capacity of 200.
If the ozone dissolution efficiency in the gas-liquid mixer is 45%, then 200
×0.01g/×45/100×100/2.25=19.75g, and a very small amount of oxygen consumption of about 20g per hour is sufficient.

Therefore, if you use a normal capacity oxygen cylinder,
Ozone can be injected for an extremely long period of time without replacing the cylinder.

In addition, the ozone concentration inside the bathtub body 1 is 0.05~
It is preferable to keep it at about 0.5 ppm.

[Effects of the invention] As detailed above, the ozone-injected bathtub of the present invention quickly sterilizes and disinfects the water (hot water) in the bathtub and decomposes organic matter, and also has the effect of improving blood circulation, making it healthier. , hygienic. Also, deodorizing,
Since it has the effect of decolorizing and deodorizing, it is easy to use and allows for extremely comfortable bathing, as well as being harmless and safe.
There is no fear of further contamination.

Furthermore, in the ozone injection bathtub of the present invention, ozone is supplied to the bathtub only in a state dissolved in hot water, so ozone gas is not introduced into the bathroom. Therefore, there is no possibility that bathroom users will inhale ozone gas or that ozone gas will irritate the bathroom users' eyes. Therefore, comfortable bathing is possible. In addition, the ozone gas that does not dissolve in the hot water is decomposed into harmless oxygen by the ozone decomposer, so the environment around the bathroom is also good.
