[Industrial applications]

 According to the present invention, the filtration device, the circulation pump, the activation tank, and the heater are connected by a circulation pipe, and the suction portion and the discharge portion of the circulation pipe face the bathtub to drive the circulation pump. The bath water circulates between the bath, the filtration device, the circulation pump, the activation tank, and the heater, during which the bath water is appropriately heated and purified. The present invention relates to a cleaning and sterilizing circulation device.

[0002]

[Prior art]

 As is well known, the domestic baths used in Japan are generally classified into the reheating type and the drop type. That is, the reheating type bath is composed of a bathtub and a heater, and the bath water is heated by naturally circulating between the heater and the bathtub.

On the other hand, the drop-in bath, which has recently become widespread, is such that hot water of a predetermined temperature is poured into a bathtub from a water heater or a hot water storage tank, for example. Each of these methods has advantages and disadvantages, and it cannot be said immediately which method is superior. For example, in the drop-in bath, hot water at a predetermined temperature is poured as appropriate, so the advantage that the bath water is relatively hygienic is recognized. However, when the temperature drops, even if hot water overflows from the bathtub, it is extremely uneconomical to add new hot water. In addition, since it is uneconomical, the drop-in type is not suitable as a bath where you can enjoy bathing 24 hours a day.

On the other hand, in the case of the reheating bath, the hot water whose temperature has dropped is heated appropriately while circulating, so there is no need to add high-temperature hot water as in the drop-in bath, and the same hot water is used many times. It has the economical advantage of being able to bathe in and is suitable as a bath where you can enjoy bathing at any time. However, as the number of baths increases, the hot water becomes contaminated with human dirt, oil, human hair, etc., and other bacteria also propagate, making it unsuitable for bathing. Therefore, a bath water purifying apparatus has been proposed, for example, in Japanese Patent Publication No. 57-17564. The purification device disclosed in the above-mentioned publication includes a pump for forcibly circulating hot water, a filter, and a water activated filtration device. Therefore, when the pump is activated and the bath water is circulated, the bath water is filtered by the filter during that time, and relatively large human hair, dirt, etc. are removed. Then, it is purified by a water activated filtration device.

Further, JP-A-54-72164 also proposes a hot water purification device in a bathtub. This device includes an inner nonwoven fabric, an outer nonwoven fabric, and an air escape pipe. The bath water is therefore filtered with this non-woven fabric, and the air that separates from the water during filtration is exhausted by the pipes.

[0006]

[Problems to be solved by the device]

 Since the above-mentioned bath water purifying device is also equipped with a filter, human hair, dirt, dust, etc. are removed from the bath hot water, and since it is also equipped with an activation device, the bath hot water is cleaned for the time being. However, there is a problem in this point because no consideration is given to odors, microorganisms, etc. that cannot be collected by the filter. In other words, microorganisms that are not removed by the filter keep the hot water at an appropriate temperature, so they may well propagate or the oil may cause a chemical reaction to change the quality of the hot water and give off a bad odor. Since it is not collected, it cannot be used for a long period of time without changing the bath water. Although it is possible to neutralize the bad odor by mixing a bath additive, etc., even if a bath additive is used, it only neutralizes the odor in the bathtub, the oil content in the bath water, etc. and does not disappear. Therefore, there is also a problem with hygiene, so it is unavoidable that it must be discarded, and the bath water cannot be used repeatedly over a long period of time. When hot water is discarded and newly poured, it requires a large amount of energy to heat to a temperature suitable for bathing, and there is also the problem of wasting water.

On the other hand, the hot-water purification apparatus disclosed in the above-mentioned Japanese Patent Laid-Open No. 54-72164 has a sterilizing ultraviolet ray lamp, so even if there is no problem with sterilization, measures against hot water odor, activation, etc. Since it is not used, it cannot be used repeatedly over a long period of time. Therefore, the present invention provides a bath water purifying and sterilizing circulation device which is more thoroughly filtered and more cleanly sanitized and sanitarily sterilized and deodorized so that it can be repeatedly used for a long period of time. Is intended to provide.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises an activation tank containing activated stones such as barley rice stone and an ozone gas generator for generating ozone gas mixed in the bath water. A bathtub for hot water that further has a filtration tank for filtering hot water, a heater for heating the bath water, and a circulation pump for circulating the bath water between the bathtub, the filtration tank, the activation tank, the heater, etc. A cleaning and sterilizing circulation device, wherein an ozone gas suction / injection pipe connected to the ozone gas generator is opened in a circulation pipe of the bath water, and the filtration tank is viewed in the circulation direction of the bath water. It is located upstream of the activation tank.

[0009]

[Action]

 Since the present invention is configured as described above, when the circulation pump is started, the bath water circulates between the bathtubs by the circulation pipe. At this time, the filtration tank, the circulation pump, the activation tank , Through the heater, etc. When circulating in this way, solid substances such as human hair and dirt in the bath water are filtered in the filtration tank.

Since the activation tank is filled with activated stones such as barley stone, the hot water decomposes bacteria or organic substances that propagate as activated stones and pass through the nutrient solution when passing through the activation tank. Then, the bacteria that get the energy of life decompose the organic matter, for example, Ammonya, which causes the bathwater to rot, and purify the bathwater. Furthermore, when the bath water is ion-exchanged, active ingredients such as magnesium, zinc, calcium, and sodium are dissolved in the bath water, and the hydrogen ion concentration of the bath water is adjusted to be weakly alkaline. As a result, a bath effect is imparted to the bath water. Further, ozone gas is injected through the ozone gas suction / intake pipe, and the ozone gas is reduced to oxygen. When it is reduced to oxygen, the microorganisms in the bath water are sterilized and deodorized, and the organic matter with a large molecular weight is decomposed into the organic matter with a small molecular weight that bacteria can decompose. In this way, when the temperature of the bath water drops while being sucked and pressurized by the circulation pump and circulating, the bath water is heated to an appropriate temperature by the heater.

【Example】

 An embodiment of the present invention will be described below. As shown in FIGS. 1 and 2, the container 1 has a substantially cubic shape, and a filtration tank 4 that constitutes a filtering device, a circulation pump 5 for circulating hot water, and a bath water are provided inside the container 1. A heater 6 for appropriately heating, an activation tank 7 for purifying bath water, and an ozone gas generator 8 are provided. The filtration tank 4, the activation tank 7, and the ozone gas generator 8 are attached to the upper wall plate of the case 1 and are suspended in the case 1.

The filtration device is roughly composed of a tubular filtration tank 4, a filtration layer 10 arranged concentrically inside the filtration tank 4, and a suction thin tube 13. An inlet pipe 9 for guiding the filtered bath water to the filtration tank 4 is connected to the side wall of the cylindrical filtration tank 4, and a discharge pipe 11 for discharging the filtered bath water is It is provided at a substantially central portion of the bottom wall of the tank 4. These inlet pipe 9 and outlet pipe 11 form a part of a circulation pipe.

The suction thin tube 13 is arranged in an internal space formed by the filtration layer 10, and an upper portion 12 thereof is open to an upper portion of this internal space. Further, the lower part is expanded in a taper shape, and the expanded part extends to the inside of the outlet pipe 11. The circulation pump 5 driven by the motor 14 is arranged near the bottom wall of the casing 1 below the activation tank 7. Therefore, when the circulation pump 5 is stopped, the hot water remains in the circulation pipe system, and the circulation pump 5 can be restarted without priming. Reference numeral 15 indicates a drain port.

The heater 6 is composed of a heater 16. The purification and sterilization circulation apparatus of the illustrated embodiment is provided with a control unit 25 of a power source, and also with a control panel for switching between automatic and manual operation, temperature setting and display of bath water, and the like. The activation tank 7 also has a cylindrical shape as shown in FIG. 1, and the inside thereof is filled with activated stones 18 such as barley stone and ceramic balls. The hot water to be treated is introduced from below the activation tank 7, and the purified bath water is configured to go out from above. An ozone gas generator 8 is housed in the container 1 as well as the circulation pump 5, the activation tank 7, and the like. The ozone gas generator 8 is composed of an ozone gas generator 20, a high-pressure transformer 21, and an air pump 22, and an end portion of an ozone gas suction / injection pipe 23 connected to the ozone gas generator 20 connects an activation tank 7 and a bath a. It opens to a reflux pipe 19 which is a part of a circulation pipe to be connected.

Next, the operation of the above embodiment will be described. First, the power supply controller 25 is turned on. Then, for example, the control panel 24 automatically sets the hot water temperature and starts the circulation pump 5. The bath water flows from the bath tub a through the inlet 2 of the circulation pipe, in the order of the filter device, the circulation pump 5, the heater 6 and the activation tank 7, and returns from the outlet 3 of the reflux pipe 19 of the circulation pipe to the bath tub a. When circulating in this way, in the filtration device, the bath water enters the filtration tank 4 through the introduction pipe 9 provided on the side wall of the filtration tank 4, is filtered by the tubular filtration layer 10, and is then filtered. It exits from the internal space formed by 10 through a lead-out pipe 11 at the substantially central portion of the bottom wall of the filtration tank 4. At this time, the air accumulated in the internal space is exhausted from the intake thin tube 13. The taper-shaped expanded portion below the intake thin tube 13 faces the inside of the outlet pipe 11, so the outlet pipe 11 is in a squeezed state, and negative pressure is generated by the circulating bath water, so that air is removed. It is effectively sucked and discharged.

When air is not sufficiently discharged and is accumulated in the internal space, that is, when air is accumulated in the upper portion of the internal space formed by the filtration tank 10, the air accumulated portion does not contribute to filtration. As a result, the filtration area is reduced and the filtration capacity is reduced. In addition, the load on the circulation pump 5 is increased, and various bacteria are inhabited in the air portion, and the bath water is putrefaction. However, according to this embodiment, since the air in the internal space is discharged from the intake thin tube 13, the above-mentioned problem does not occur. Moreover, even if the bath water is discharged from the suction thin tube 13 together with the air, since the bath water is filtered by the filter layer 10, the suction thin tube 13 may be clogged with human hair, dirt, etc. Nor.

The bath water sucked by the circulation pump 5 is sent under pressure to the heater 6 and heated by the heater 16 to a set temperature. Then, it is pressure fed again to the activation tank 7. Since the activation tank 7 is filled with the activated stone 18 such as barley stone, the hot water is purified when passing through the activation tank 7. At this time, the bath water flows in the tank 7 from the lower side to the upper side against the gravity, so that the hot water does not flow evenly in the activated stone 18 and is not shot, and the activated stone 18 is effectively used. . The bath water discharged from the activation tank 7 returns to the bath a through the reflux pipe 19, but at this time, ozone gas from the ozone gas generator 20 is appropriately injected into the bath water by the air pump 22 to sterilize the bath water. Treatments such as deodorization and decomposition of organic substances are performed.

According to the present embodiment, as described above, it is filtered by the filtering device, purified by the activated stone 18, and sterilized and deodorized by ozone gas, so that the bath water is suitable for drinking. Purified. This was proved by the analysis results of the bath water used for two weeks by the Japan Food Analysis Center, a foundation in Motoyoyogi-cho, Shibuya-ku, Tokyo, and social welfare corporation + character society (Setagaya-ku, Tokyo) It is also proved by the analysis results of an average of 110 people a day in February, and a request to the Tokyo Metropolitan Institute of Public Health (3-24-1, Hyakunincho, Shinjuku-ku) for bathing water.

[Effect of device]

 As described above, according to the present invention, since the activation tank containing activated stones such as barley stone and the ozone gas generator for generating ozone gas mixed in the bath water are provided, that is, the activation tank. And the ozone gas generator are combined, the following effects peculiar to the present invention can be obtained. First, when the hot water passes through the activation tank, it decomposes the bacteria that multiply by activated stones and carry out other nourishment, that is, the organic matter, and the bacteria that obtain the energy of life cause the organic matter, for example, the bath water, to be decomposed. , Purifies the bath water by decomposing dirt, etc. Furthermore, the hot water is ion-exchanged and the active ingredients such as magnesium, zinc, and calcium are dissolved in the hot water, and the hydrogen ion concentration of the hot water is adjusted to be weakly alkaline. As a result, the bathing effect is added to the bath water. When ozone gas is reduced to oxygen in bath water, bacteria in the hot water are sterilized, deodorized, and decomposition of organic matter such as scale is promoted. Ozone gas is reduced to oxygen and becomes dissolved oxygen. Therefore, the growth of aerobic bacteria that live in the activation tank becomes active by mixing ozone gas, and the purification of the bath water by the aerobic bacteria in the activation tank is further promoted. Further, the ozone gas decomposes organic substances having a large molecular weight. Therefore, even a large molecular weight organic substance that cannot be decomposed by bacteria can be decomposed by mixing ozone gas. Solids such as human hair and dirt are filtered by the filtration tank. Therefore, according to the present invention, the bath water is more thoroughly filtered, cleaned more cleanly, and sanitized and deodorized more hygienically, so that it can be repeatedly used for a long period of time. Also, when the activation tank is installed on the upstream side of the filtration tank as viewed in the circulation direction of the bath water, relatively large foreign matter such as human hair is captured by the activation tank, and the downstream filtration tank Both the activation tank and the filtration tank have to be cleaned as small foreign objects are trapped, but according to the present invention, the filtration tank is located upstream of the activation tank, so the activation tank is activated. Bath water filtered by the filtration tank will flow into the tank, and the activation tank will not be clogged with foreign matter such as human hair. Therefore, it is possible to obtain the effect that it can be used for a long period of time by simply cleaning only the filtration tank.
