BACKGROUND OF THE INVENTION Proposals have been made to make bathing at home more comfortable. One of these is a blow bath, which massages the body by jetting air bubbles and water into the bathtub with considerable force. Apart from this, there are also systems that circulate, filter, and sterilize the hot water in the bathtub so that the next bather can enjoy clean water, and there are also systems that circulate the hot water in the bathtub so that the next bather can comfortably bathe in clean water. There are also water filters that can be used multiple times. Many products of this type use a pump to circulate hot water into the bathtub, mixing air bubbles and spraying the mixture into the bathtub. Unlike the blow bath mentioned above, this type of bath uses a not-so-powerful jet of foam to flow into the bathtub, and uses the ultrasonic waves produced when the bubbles pop to stimulate the skin, aiming for a health effect.

[0003] Most of these products use natural stones such as maifan stone (quartz porphyry) to purify hot water, and utilize the trace amounts of minerals eluted from the stones, while also using the stones as filter media. It is also used to help stabilize bacteria in hot water. However, since this alone is insufficient for sterilization, there are many proposals using various sterilization methods such as metal ions, ozone, and ultraviolet rays as supplementary means.

The first problem is filtration. This type of hot water sterilization/filtration equipment installed outdoors uses filters made of natural stone, urethane, nonwoven fabric, etc. as filter media, but natural stone Because the unevenness of the filter does not lend itself to backwashing, it must be cleaned by hand after a certain period of time, and similarly, filters made of urethane or non-woven fabric must be washed by hand or thrown away. and,
Cleaning is a pain even if you only do it once or twice a year.

[0005] Therefore, there are devices that use ceramic spheres or glass beads made of kaolin or zeolite as filter media, and wash the filter media by backflowing the hot water at regular intervals or by sensing the water pressure of the hot water. This method uses hot water for backwashing, so the
Household bathtubs, which are about liters in size, often have 5 liters of water.
Since 0 to 60 liters of hot water is used as backwash water, the water level in the bathtub drops, and replenishing the water becomes difficult, so consideration must be given to automating replenishment. In addition, automatic backwashing equipment has a major problem of increased cost.

The second problem is sterilization. Natural stones such as maifan stone have the effect of eluting minerals, and bacteria in the hot water are adsorbed to the fine voids in the montmorillonite and kaolionite parts of the stone and sterilized. Furthermore, the microbial film grown on the surface of the stone can be fully evaluated in that it has the function of decomposing fat in hot water and reducing it to organic acids, but the inventor's experimental results indicate that We did not have sufficient confidence in the adsorption stability of bacteria. Perhaps for this reason, many devices use ozone sterilization as an auxiliary method.

Originally, the main purpose of this type of equipment is to purify hot water, but ultrasonic bubbles for health purposes are also requested by users. For this reason, even when using ozone, many bathtubs use a discharge nozzle to inject ozone bubbles instead of air bubbles into the bathtub. Although this method is simple, there are problems with ozone damage, such as damage to plastic bathtubs, bathroom tiles, bathtub lids, aging and discoloration, and the effects on the human body cannot be ignored. In this regard, it is not inconceivable to use a timer to inject ozone outside of bathing hours, but although the effect on the human body can be eliminated, the harm to the bathroom cannot be eliminated.

On the other hand, instead of sending ozone directly into the bathtub, ozone is mixed with hot water and sent to the reaction tower, and the bubbles containing ozone are brought into good contact with the hot water and sterilized.
There is a method of releasing ozone into the atmosphere and sending only sterilized hot water into the bathtub. According to this method, the hot water is sterilized and does not contain ozone, so there is no harm to the human body or the bathroom. However, there are problems with feeding ozone into the reaction tower. That is, if the reaction tower is placed upstream of the pump, it is difficult to release ozone after the reaction. In addition, it is not practical to send hot water mixed with ozone bubbles sucked in from the negative pressure side directly through the pump to the reaction tower on the downstream side, as this will only cause the pump to idle due to air and cause damage to the pump blades due to ozone. It is possible.

[0010] Therefore, it is common practice to place a reaction tower downstream of the pump, but since side pressure is applied to the downstream pipe, in order to send ozone, the pressure in the pipe must be exceeded. Either you have to rely on an air pump with air capacity, or you have to install an ejector with an orifice in the same line. However, since the former increases costs, the latter is more desirable in terms of cost and simplification, but there is a problem in disposing it in the circulation path. In other words, the orifice that works by sucking ozone also works by reducing the flow rate at the same location, so it is no longer able to provide a flow rate that is sufficient to suck air into the hot water that passes through the ejector for bubble growth at the outlet of the bathtub. Either the bubble bath must be given up or a separate means for bubble growth must be added.

[0011] The third problem is that various bath additives have been developed and used as lifestyles have changed to make bathing more comfortable and healthier. When used together with ozone, chlorine agents, etc., the bath additives will be decolorized and deodorized by their oxidizing power, resulting in extremely short service life of the bath additives. In addition, when natural stones such as Maihan stone or ceramic balls made of adsorbent materials such as montmorillonite or kaolionite are used as filter stones, the sodium sulfate in the bath additive reacts with the calcium in the filter medium to form a film on the surface of the filter medium. Perhaps because of this, the filtration performance deteriorates significantly in a short period of time. Also, because it does not completely absorb pigments and fragrances, it has the disadvantage that some bath additives may be bleached or remain the same color.

[Means for solving the problem] Regarding the first problem, the main sterilization element and the filtration element with auxiliary sterilization ability are separated, the main sterilization is performed outdoors, and the auxiliary sterilization and necessary Perform adequate filtration only indoors, in bathtubs. A small filter is sufficient if the hot water in the bathtub in a general household is dirty, and it is installed at one place in the hot water circulation system, that is, at the suction port inside the bathtub, so that it can be attached and removed from inside the bathtub. so that it can be removed for washing and cleaning when taking a bath. As for the timing of cleaning, since the filter becomes clogged and the air bubbles are not ejected easily, it is easy to tell by looking at it, and it is enough to clean it once every 2 to 3 days. If the filter is, for example, a water-resistant urethane sponge (10 cm in diameter, 1 cm thick, with 30 meshes per 25 mm length), the inventor's experiments have shown that there are differences depending on the degree of dirtiness and age of the bather. However, it is sufficient to clean the bath every 10 to 20 people, and by increasing the suction surface area, the cleaning interval can be extended. In addition, the sterilization/filtration element can be attached to and removed from the suction port by mounting with a stopper or screws, but simply by inserting the connection port of the sterilization/filtration element into the suction port, the suction pressure of the pump will work and the element will fall off. do not.

[0014] The sterilization/filtration element is preferably a flat type that has a large inlet area for hot water and a large contact area for both the filter and the metal ion generator, and the filter is similarly easy to clean. For example, this filter can be made by combining two waterproof urethane sponges with different meshes, one coarse on the inlet side and one fine on the back side, or a micro-sponge-like waterproof urethane sponge on the inlet side and ultra-superfine fibers on the back side. A mode in which non-woven fabric is combined,
Examples of metal ion generators include amorphous copper,
Examples include embodiments in which it is supported on a water-permeable net-like body such as high-purity ultrafine copper fibers or ceramic silver carriers, and embodiments in which it is supported on a water-resistant urethane sponge or nonwoven fabric of a filter. The assembled structure of the filter and the metal ion generator is, for example, one in which the filter is held on the suction port side, and the metal ion generator is held in a net-like body that allows water to pass through on the opposite side, leaving an inflow space for hot water in between. A mode in which the metal ion generator is placed facing each other in a state facing each other, a mode in which the metal ion generator is held in a water-permeable net-like body and polymerized on the rear side of the filter, and a mode in which the metal ion generator is placed facing each other in a water circulation system downstream of the filter. Examples include an embodiment in which a metal ion generator is disposed between the suction port and the pump so that it can be drawn out from the suction port of the bathtub.

Regarding the second problem, an ejector is provided upstream of the ozone sterilization reaction tower, an ozone generator is connected to the orifice of the ejector, and ozone is sucked in without power. Although this flow rate is sufficient for filtration, it is insufficient for use in a bubble bath, so a bypass line that is opened and closed by a solenoid valve is provided upstream of the ejector, and this line is opened and circulated during the bubble bath. This solenoid valve can be operated from inside the bathroom when taking a bubble bath. Additionally, the power to the ozone generator can be turned on and off from within the bathroom. Further, the solenoid valve is not limited to one made of gunmetal, but may be made of plastic, which is selected as appropriate.

Regarding the third problem, an ozone sterilization element and a metal ion sterilization element are used in combination in order to sterilize the hot water without adversely affecting the bath preparation. Conventionally, ion sterilization has been performed by eluting copper ions into water from ultrafine fibers of high-purity copper, or by eluting silver ions into water from silver supported on fibers or solid materials. However, recently it has become possible to take advantage of the property of amorphous copper and silver, which do not form an oxide film on their surfaces, to immerse the same metals in water and emit ions for a long period of time.

[0017] When this metal ion sterilization method was applied to hot water in a bathtub and tested, although it did not have as strong a sterilizing power as ozone or chlorine, the inventor repeated the experiment every week for three months. So, general bacteria is 8 per 1 mg of hot water.
The temperature was between 0 and 1600, and the water was clear and could withstand continuous use. However, although metal ion sterilization can suppress the growth of bacteria, it does not have the oxidizing power of ozone, so its ability to decolorize and deodorize hot water is inferior, and after long-term use, hot water may become slightly colored and It gave off a smell. Therefore, in the present invention, this point is used conversely when using bath additives, and the ozone generator is stopped while bath additives are being used. Leave it to me. After one day of bathing using the bath additive in this manner, the bath agent may be switched to ozone sterilization and a new bath agent may be added the next day, or it is also possible to use metal ion sterilization continuously for several days. Of course, the filtration is done continuously during that time, so the hot water is transparent.

[Function] The hot water sterilization element is separated outdoors, the sterilization/filtration element is separated indoors at the suction port inside the bathtub, and the bypass path upstream of the ejector in the hot water circulation system can be opened and closed by a solenoid valve. While hot water is sucked in from the suction port, passed through the circulation system, and returned to the bathtub from the discharge port for sterilization and filtration, the removed substances and some bacteria in the hot water are sterilized and filtered at the suction port. Most of the bacteria in the hot water are sterilized in the downstream ozone reaction tower, and ozone is separated and removed from the hot water in the same reaction tower.
Sterilized and filtered hot water is returned to the bathtub. As a result, the hot water in the bathtub is almost sterilized, clear and free of dirt.
You can always maintain the same bathing condition as the first bath.

Then, the solenoid valve is opened to open the bypass system, and the hot water is sucked in through the suction port, detoured to the bypass system on the way to the ejector in the circulation system, and then returned to the bathtub from the discharge port for sterilization.・During filtration, the removed substances and some bacteria in the hot water are sterilized at the suction port. ・After being sterilized and filtered by the filtration element, most of the hot water is passed through the bypass system at the same flow rate as it was sucked in from the suction port. On the other hand, the remaining hot water passes through the ejector and flows into the ozone reaction tower, where it is sterilized and then merges with the hot water on the side of the bypass system to reach the discharge port.

B. Open the solenoid valve to open the bypass line,
While the hot water is diverted to the bypass system on the way to the ejector in the circulation system and returned to the bathtub from the discharge port for sterilization and filtration, the removed substances and some bacteria in the hot water are removed from the inlet. Most of the hot water is filtered and sterilized by the sterilization/filtration element, and most of the hot water passes through the bypass system and flows to the discharge port at the same flow rate as it was sucked in from the suction port, while the remaining hot water passes through the ejector and flows into the ozone reaction tower. After flowing in and sterilizing most of the bacteria, it joins the hot water on the side of the bypass system and reaches the discharge port, where the water force is strong and the sterilized and filtered hot water can be vigorously refluxed with air bubbles into the bathtub. Therefore, the hot water in the bathtub is almost sterilized, transparent and free of dirt, and moreover, the user can enjoy the bathing experience of a bubble bath.

C. During normal bathing or bubble bathing as described above, when bathing agents are added to the hot water, the ozone generator is stopped, and the hot water is being circulated, the removed substances and some bacteria in the hot water will be removed from the inlet. After being sterilized and filtered by the sterilization/filtration element, it reaches the discharge port, and the bacteriostatic and filtered hot water containing the bath agent can be returned to the bathtub. Therefore, since there is no effect of ozone even if the bath additive is added, the user can enjoy bathing with the bath additive in either a normal bath or a bubble bath.

D. Unlike conventional devices, there is no filter or filter stone placed inside the filtration tank, so there is no need to open and clean the filtration tank, and the ozone generating element only needs to be replaced once every few years, requiring almost no maintenance. Furthermore, since there is no need to backwash the filter media, there is less worry about the device breaking down.
