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, the present invention can more completely antibacterial or sterilize various bacteria in bathwater with less antibacterial elements, It is an object of the present invention to provide a bath water sterilizing and purifying apparatus for purifying water.

The revolving cylinder 30 includes a first revolving cylinder 31 and a second revolving cylinder 32, as described in detail in Japanese Patent Application No. 9-142998 filed by the present applicant. ing. The first revolving drum 31 has a substantially cylindrical shape as a whole, and one is closed by a side wall. The other is open, and a flange 33 is integrally formed on the periphery so as to spread outward in a radial direction. An inlet pipe e for supplying the bath water to the first rotating body 31 is provided substantially in a tangential direction on the cylindrical portion of the first rotating body 31. Therefore, the first from the inlet pipe 3
When the hot water is supplied to the revolving drum 31, the bath water revolves in the first revolving drum 31, and a negative pressure region is formed at the center. The second revolving drum 32 forms a pair with the first revolving drum 31 and has the same size and shape as the first revolving drum 31, and has a substantially cylindrical shape as a whole. It is closed by a side wall 35. And around the other opening edge,
The flange 34 is likewise integrally formed so as to extend radially outward. An outlet pipe f from which the swirled hot water flows out is provided in a substantially tangential direction in the cylindrical portion of the second swirling body 32. The first turning cylinder 31 and the second
The revolving drum 32 is integrated by abutting flanges 33, 34 with each other with a partition wall interposed therebetween, and tightening them with bolts and nuts. The outlet pipe f is connected at one end to a return pipe g attached to the bathtub YS.

The partition partitions the first turning drum 31 and the second turning drum 32, and has a central opening. Therefore, the bath water swirled in the first swirl body 31 enters the second swirl body 32 through the opening, and also swirls in the second swirl body 32 to exit from the outlet pipe f. Become. In this way, the bath water is the first and second revolving drums 3.
Since it turns within 1, 32, a negative pressure area is formed at the center. Therefore, an ozone gas supply pipe 43 to be described later is provided so as to open to a negative pressure region at the center.

The ozone gas generator 40 comprises an ozone gas generator 41, an air pump 42 and the like. The ozone gas supply pipe 43 has a check valve 44 interposed therebetween, and is attached so as to open at a substantially central portion of the revolving drum 30 described above. The ozone gas generator 41 and the air pump 42 are connected by an air supply pipe 46 in which a solenoid valve 45 is interposed. Therefore, when the ozone gas generator 41 is turned on and the electromagnetic valve 45 is opened to start the air pump 42, relatively high-pressure air containing ozone gas is supplied to substantially the center of the revolving drum 30.

Next, the operation of the above embodiment will be described. Although not specifically described, the bath water sterilizing and purifying apparatus according to the present embodiment also includes a control device having a timer, preferably a weekly timer. Therefore, 1
When the time is up several times a day or several times a week, the circulation pump 10 starts. Therefore, the bath water in the bathtub YS returns to the bathtub from the return pipe k through the filtration tank 1, the circulation pump 10, the antibacterial container 20, and the swirling body 30. Thereafter, the bath water is circulated in the same manner.

While the bath water is circulating as described above, solids are removed in the filtration tank 1 in a known manner. Further, the antibacterial material Z provided in the antibacterial container 20 also sterilizes 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.

According to the sterilization time, the ozone gas generator 4
When the starting time reaches 0, the ozone gas generator 41, the solenoid valve 45, the air pump 42, etc. are turned on. Relatively high-pressure air containing ozone gas is supplied to a substantially central portion of the revolving drum 30. The ozone gas supplied to the revolving drum 30 is mixed and stirred with the bath water, and microorganisms and bacteria such as Legionella bacteria in the bath water are sterilized. That is, bacteria such as Legionella bacteria that have survived without being sterilized by the antibacterial agent are sterilized, and the offensive odor is deodorized. Organic substances having a large molecular weight that bacteria cannot decompose are decomposed. Then, the ozone gas becomes dissolved oxygen to assist the propagation of the aerobic bacteria growing in the activated stone, and the bath water is further purified.

As an option, the lid 5 is placed on the antibacterial container 20.
0, the silver ion generating electrode 60 of the lid 50
Is soaked in the bath water in the antibacterial container 20. Therefore,
As described above, when the bath water is circulating, the pair of electrodes 6
When a current is passed through 1 ′, 62 ′, or a pair of electrodes 6
When an electric current is applied to 1 'and 62', the circulation pump 10 is activated and the bath water circulates. Silver ions are mixed into the bath from the silver ion generating electrode 60. Thereby, various bacteria in the bath water are sterilized. At this time, the ozone gas containing air is strongly mixed with the bath water in the revolving drum 30 and thus is sterilized by the ozone gas. However, since silver ions are previously mixed in the bath water, Owing to the synergistic effect, ozone gas is sterilized more completely than sterilized by 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 62 is formed in a net shape, the area of the cathode 624 is increased, and the generation efficiency of silver ions is improved. In addition, the net-shaped cathode 62 prevents a short circuit when the bath water flows in the antibacterial container 20. When the electrodes are worn, the entire electrode mounting body 65 is replaced.

The present invention can be implemented in various forms without being limited to the above embodiment. For example, filtration device 1,
It is apparent that the same operation can be performed even if the circulation pump 10, the antibacterial container 20, the revolving drum 30, and the like are arranged in a different order from the illustrated embodiment. It is also apparent that the silver ion generating electrodes 61 'and 62', the ozone gas generator 40, and the like can be manually turned on and off. Moreover,
An electric heater may be provided 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.

[0023]

As described above, according to the present invention, the antibacterial purifying apparatus is composed of a combination of an antibacterial container containing an antibacterial material and an activated stone and an ozone gas generator, so that it can be used alone. Compared to the case of sterilization with a small amount of antibacterial element due to a synergistic effect, for example, pathogenic E. coli O-15
7. An effect peculiar to the present invention is obtained, which is capable of sterilizing Legionella bacteria and the like, which are said to cause pneumonia. 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. Moreover, according to the present invention, the gas supply pipe of the ozone gas generator is opened substantially at the center of the swirling body, so that the ozone gas is swirled and mixed strongly with the bath water to further enhance the effect of the ozone gas. Further, according to another invention, a lid provided with silver ion generating electrodes can be selectively attached to the antibacterial container, and when the lid is attached, the silver ion generating electrodes become antibacterial. Silver ions elute into the bath water when it reaches the bath water in the container, so just select the lid and attach it, sterilization with three kinds of antibacterial elements, antibacterial agent, silver ions, and ozone gas Alternatively, antibacterial effects can be obtained, and the effect of being able to meet user demands at low cost is further obtained.
