The present invention relates to a bathtub and a circulating pump connected by a circulating pipe system. When the circulating pump is driven, hot water in the bathtub circulates through the circulating pipe system.
The present invention relates to a triple-type antibacterial purifying device for bathwater, in which various bacteria in the bathwater are antibacterial or sterilized, and the bathwater is purified.

[0002]

2. Description of the Related Art A filtration device for removing solid matter such as human hair in bath water, a water pump for forcibly circulating bath water,
An activation device containing activated stones such as ceramics, shell fossils and barley stone, an ozone gas generator for generating ozone gas having effects such as sterilization and deodorization, a heater for heating bath water to a predetermined temperature, The bath water purifying device equipped with a control device for controlling the mixing time of the ozone gas, the heater, etc.
Applicant has disclosed Japanese Utility Model Laid-Open No. 6-48893, Japanese Patent Laid-Open No. 7-1.
Many proposals have been made in, for example, Japanese Patent No. 85574 and Japanese Utility Model Publication No. 6-23203. Since these bath water purifying devices are provided with an activating device, when the bath water passes through the activating device,
Bacteria that propagate on the activated stones and live in other nutrients decompose organic matter, for example, Ammonya, which causes the bath water to spoil, and purify the bath water. Further, the bath water is ion-exchanged, and 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 slightly alkaline. Thereby, a bath effect is imparted to the bath water.

[0003] Further, since the ozone gas generator is provided, various bacteria in the bath water are sterilized by the ozone gas. In particular, Legionella bacteria, which are said to cause pneumonia, are also effectively sterilized. In addition, an action such as decomposition and deodorization of organic substances having a large molecular weight that bacteria cannot be decomposed can be obtained. Furthermore, the ozone gas becomes dissolved oxygen to assist the propagation of the aerobic bacteria growing in the activation device, and the effect of further promoting the purification by the bacteria can be obtained.

[0004]

As described above, according to the bath water purifying apparatus proposed by the present applicant, the bath water has a bathing effect, and various bacteria are sterilized by ozone gas. There is no particular problem. However, depending on the amount of ozone gas, the length of mixing time, etc., it may not be possible to sufficiently sterilize. Even if it is not completely sterilized, sterilization is not a problem for healthy people, but it can be transmitted to people with reduced immunity and physical strength. In addition, pathogenic Escherichia coli O-157, which has recently become a problem,
It is said that even if the number of bacteria is extremely low, the disease will be sick, and more complete sterilization is required from the emotional aspect of bathers.

[0005] Such a demand can be satisfied by mixing a large amount of ozone gas into bath water. Also,
Although it is known that silver ions, chlorine, and the like have a bactericidal action, the above requirements can be satisfied by using a large amount of these antibacterial elements. However, ozone gas becomes dissolved oxygen after exerting a bactericidal action, an oxidizing action, etc., so there is no problem, but it is desirable that the amount of other antibacterial elements used is small. The present invention seeks to provide an antibacterial purifying device that satisfies the above-mentioned requirements. Specifically, it is possible to more completely antibacterial or sterilize various bacteria in the bath with a smaller number of antibacterial elements, It is an object of the present invention to provide a triple-type antibacterial purifying device for bath water to be purified.

It has been confirmed that it is 5 ppm. The antibacterial agent Z having such an excellent antibacterial action is put into a net for a predetermined amount, and put together with the net, for example, in the upper side of the tank 11.

Examples of the active stone K include fossil shellfish and barley stone. These active stones K are natural ores containing silica, aluminum oxide, etc. as a main component and containing iron, manganese, magnesium, potassium, phosphorus, titanium and the like, or ceramics made from these, and the active ingredient is composed of these active stones. Is dissolved in the bath, and the bath is adjusted to have a weakly alkaline hydrogen ion concentration. Thereby, a bath effect is imparted to the bath water. Such activated stones are also put in the net and put under the tank 11. An antibacterial discharge pipe d is attached near the top of such a tank 11, and this antibacterial discharge pipe d branches into a main conduit D and a sterilization circuit e. Also, antibacterial container 10 can contain radium ore to obtain the same effect as rajumu hot spring.

The silver ion generator 20 comprises a silver ion electrode casing 21 and an electrode or a lid 22 which closes the opening of the silver ion electrode casing 21 in a liquid-tight manner. The silver ion electrode casing 21 has a three-way joint shape, and is interposed in a sterilization circuit e branched from the main conduit D using both joint portions. And the opening 2 corresponding to the third joint
An electrode to be described later is exchangeably provided at 1 '. As described above, since the silver ion electrode casing 21 is interposed in the sterilization circuit e, a cascade pump 35 described later in detail is used.
The bath is only available when the silver ion electrode casing 2
1 and silver ions are mixed into the bath at that time. An anode 23 made of a silver rod is attached in an insulated state to the back side of the lid 22, that is, a portion located on the silver ion electrode casing 21 side. Are provided in an insulated state. A pair of electrodes 23 ′ and 24 ′ that are electrically connected to the anode 23 and the cathode 24, respectively, are attached to the front side of the lid 22, and one of the electrodes 23 ′ has, for example, a positive current of an electrical component. The source and the other electrode 24 'are connected to a negative current source, respectively.

Although not shown in FIG. 1, a female screw is formed in the opening 21 ′ of the silver ion electrode casing 21, while the opening of the silver ion electrode casing 21 is formed on the back side of the lid 22. A male screw that is screwed to the female screw 21 ′ is formed. Therefore, in order to attach the electrode to the silver ion electrode casing 21, it is only necessary to screw the male screw of the lid 22 into the female screw of the opening 21 ′ of the casing 21,
In addition, replacement of the electrode together with the lid 22 can be easily performed.

The cascade pump 35 is, as is well known,
The motor 36 includes a centrifugal pump having a number of blades.
It is designed to be driven to rotate. The suction pipe h is connected to the suction port. A discharge pipe j is connected to the discharge port. The ozone gas generator 30 is
A check valve 32 is interposed in the gas supply pipe 31 which is well known in the art, and is opened at a substantially central portion of the cascade pump 35. Therefore, when the ozone gas generator 30 and the solenoid valve 34 are turned on while the cascade pump 35 is operating, the air supplied from the air supply pipe 33 and the ozone gas in which a part of the supplied air is ozonized are converted into the cascade pump 35. Will be sucked into the negative pressure section in the inside.

In the present embodiment, as a heater for heating the bath water, a heat exchanger 40 is provided in a return pipe k where the main pipeline D and the sterilization circuit e join. The heat exchanger 40 has a first,
For example, the first header 41 is configured as a heat transfer tube type in which a plurality of heat transfer tubes are provided between the two headers 41 and 42.
A supply pipe 45 for a high-temperature fluid is connected to the second header 42, and a discharge pipe 46 from which a low-temperature fluid is exchanged with the bath water through the second header 42. The supply pipe 45 and the discharge pipe 46
3 connected to the supply pipe 45 by a short-circuit pipe 48
By switching the direction valve 47, the high-temperature fluid flows in a short-circuit manner toward the first header 41 or toward the discharge pipe 46. The supply pipe 45 and the discharge pipe 46
Are connected to a boiler, but the boiler is not shown in FIG.

Next, the operation of the above embodiment will be described. Although not specifically described, the triple type antibacterial purifying apparatus for bath water according to the present embodiment also includes a control device having a timer, preferably a weekly timer. Therefore, when the time is up several times a day or a week, the circulation pump 4 is normally started. Accordingly, the bath water in the bathtub not shown in the figure returns from the return pipe k to the bathtub through the solenoid valve v, the hair catcher 1, the filtration tank 6, the antibacterial container 10, the main conduit D and the heat exchanger 40. Thereafter, the bath water is circulated in the same manner. Since the sterilization circuit e is provided with the silver ion generator 20, the cascade pump 35, and the like, the flow resistance is large, and the bath water flows toward the main conduit D having a small resistance.

When the bath water is circulating as described above, large foreign matters such as human hair are removed in the hair catcher, and fine solids are removed in the filtration tank 6. Further, the antibacterial material Z provided in the antibacterial container 10 also kills various bacteria such as pathogenic Escherichia coli O-157. As is well known in the art, active ingredients such as magnesium, zinc, calcium, and sodium are dissolved in the bath water by the active stone K, and the bath water is adjusted to have a slightly alkaline hydrogen ion concentration. Thereby, a bath effect is imparted to the bath water. In addition, the organic matter is decomposed by bacteria that propagate on the activated stone and live in other lives, and the bath water is purified. When the temperature of the bath water is equal to or lower than the set temperature in the heat exchanger 40, a high-temperature fluid is supplied from the boiler to the first header 41 via the three-way valve 47. The high-temperature fluid flows from the first header 41 to the second header 4 through a plurality of heat transfer tubes.
Flow to 2. At this time, the counter-current bath water is heated. The heat-exchanged and cooled fluid returns to the boiler through the discharge pipe 46. Similarly, when the time is up or when the hot water temperature becomes lower than the set temperature,
The circulation pump 4 is activated and the bath is sterilized, purified and heated.

The cascade pump 35 depends on the sterilization time.
, The cascade pump 35 is activated, and the silver ion generator 20 and the ozone gas generator 3 are activated.
The 0 switch, the solenoid valve 34 and the like are also turned on. During the ozone time, the circulation pump 4 is also activated. As a result, the bath water circulates as described above, but a part of the bath water moves toward the main conduit D.
The remainder flows toward the sterilization conduit e. Silver ion generator 2
At zero, silver ions are mixed into the bath. Thereby, various bacteria in the bath water are sterilized. Further, ozone gas is sucked into the negative pressure part of the cascade pump 35 together with air. Ozone gas containing air is supplied to the cascade pump 35
Strongly mixed with bath water by impeller. Although sterilized by the ozone gas, since silver ions are previously mixed in the bath water, the bath water is more completely sterilized by a synergistic effect than in the case of sterilizing ozone gas alone. As described above, since the bacteria are sterilized by the synergistic effect, the amount of silver ions can be reduced.

According to the present embodiment, since the cathode 24 is formed in a net shape, the area of the cathode 24 is increased, and the generation efficiency of silver ions is improved. Further, the bath water is supplied to the silver ion electrode casing 2 by the net-shaped cathode 24.
Short circuit is prevented when flowing through the interior of the device. In addition,
When the electrodes are worn, the entire lid 22 is replaced.

Next, the bath water mixed with the ozone gas is
Merge with the return pipe k and reflux to the bathtub. The bath is thus filtered, purified, sterilized and heated to a predetermined temperature. When the set time elapses, that is, when the time set to almost completely sterilize the germs in the bath water elapses, the silver ion generator 20, the ozone gas generator 30, the cascade pump 35, and the like are turned off, and the sterilization is stopped. To end. Thereafter, sterilization is performed in the same manner. in this way,
According to the present embodiment, since sterilization is performed for a relatively long time and almost completely, sterilization is performed on a daily basis. However, it is possible to suppress the propagation of various bacteria more than incomplete sterilization several times a day.

The present invention can be implemented in various forms without being limited to the above embodiment. For example, a circulation pump 4, a filtration device 5, an antibacterial container 10, a silver ion generator 20,
It is obvious that the same operation can be performed even if the ozone gas generator 30, the cascade pump 35, the heat exchanger 40 and the like are arranged differently from the illustrated embodiment. It is also apparent that the silver ion generator 20, the ozone gas generator 30, and the like can be manually turned on and off. Further, an electric heater may be provided instead of the heat exchanger 40 as a heater at an appropriate position in the circulation pipeline system. It is also apparent that the operation can be performed without a heater when a heating source is separately provided.

As described above, according to the present invention, the antibacterial purifying apparatus comprises a combination of an antibacterial container containing an antibacterial material and an active stone, a silver ion generator, and an ozone gas generator, The antibacterial container and the silver ion generator are interposed in the circulation pipeline so that the bath water flows through the interior, and the gas supply pipe of the ozone gas generator is opened to the negative pressure part of the circulation pipeline. Therefore, it is sterilized or antibacterial with three kinds of antibacterial agents, silver ions, and ozone gas. Compared with the case of sterilizing alone, a small amount of antibacterial elements is used due to a synergistic effect. For example, pathogenic Escherichia coli O-1
57, an effect peculiar to the present invention is obtained that Legionella bacteria, which are said to cause pneumonia, can be sterilized.
At this time, effects such as decomposition and deodorization of organic substances having a large molecular weight that bacteria cannot be decomposed by ozone gas are obtained, and the bath water is purified.
