DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bathtub and a cascade pump connected by a circulation pipe system. When the cascade pump is driven, bath water in the bathtub circulates through the circulation pipe system. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a superimposed type antibacterial device for bath water in which various bacteria in the bath water are antibacterial or sterilized by the antibacterial device.

[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] In addition, since the ozone gas generator is provided, various bacteria in the bath water are sterilized by the ozone gas. Legionella bacteria, which are said to cause pneumonia, are particularly 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. Emotional aspects of bathers also require more complete sterilization. Such a demand can be satisfied by mixing a large amount of ozone gas into bath water. Further, it is known that silver ions, chlorine and the like have a bactericidal action, but the above demand 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 device that satisfies the above-mentioned requirements, and more specifically, an antibacterial device for bath water that can more completely antibacterial or sterilize various bacteria in bath water with less antibacterial elements. It is intended to provide.

[0005]

As described above, although ozone gas has a bactericidal action and silver ions also have a bactericidal action, the present invention enhances the bactericidal effect by combining ozone gas and silver ions. It has been experimentally found that a high bactericidal effect can be obtained with a small amount of silver ions, and the ozone gas generator and the silver ion generator are combined. That is, in order to achieve the above object, according to the present invention, a bathtub and a cascade pump are connected by a circulation pipeline system, and when the cascade pump is driven, hot water in the bathtub circulates through the circulation pipeline system. A superimposed antibacterial device for bath water, in which germs in the bath water are antibacterial or sterilized by the antibacterial device, wherein the antibacterial device is a combination of a silver ion generator and an ozone gas generator. Wherein the silver ion generator is interposed in the circulation line system so that bath water flows therethrough, and a gas supply pipe of the ozone gas generator opens to a negative pressure portion of the circulation line system. It is configured as follows. The invention described in claim 2 is configured such that the negative pressure section described in claim 1 is a negative pressure section inside the cascade pump.

A circulation pipe system is constituted by the first and second discharge pipes 33, the gas-liquid separator 20, the second discharge pipe 34, the bathtub 30, and the like.

In the illustrated embodiment, a hair catcher 50 and a solenoid valve 60 are provided upstream of the silver ion generator 1.
And are interposed. The hair catcher 50 is composed of a container body 51 and a filter body provided inside the container body 51 so as to be exchangeable or washable, and a lid 52 for closing an opening of the container body 51 is provided with a bolt 53. , 5
3,... Are detachably provided on the container body 51.

The silver ion generator 1 includes a silver ion electrode casing 2 and an opening 2 ′ of the silver ion electrode casing 2.
And an electrode or lid 3 which is adapted to close liquid-tightly. The silver ion electrode casing 2 has a shape of a three-way joint, and is interposed in the second suction pipe 32 of the cascade pump 10 using both joint portions. Then, an electrode to be described later is exchangeably provided in the opening 2 'corresponding to the third joint. Lid 3
An anode 4 made of a silver bar is attached in an insulated state to the back side of the electrode, that is, a portion located on the side of the silver ion electrode casing 2, and a net-shaped cathode 5 is similarly insulated so as to surround the anode 4. It is provided in. As described above, since the cathode 5 has a net shape, the area of the cathode 5 is widened, and the generation efficiency of silver ions is improved. In addition, the net-shaped cathode 5 prevents a short circuit when the bath water flows through the silver ion electrode casing 2.

A pair of electrodes 4 ', 5' electrically connected to an anode 4 and a cathode 5, respectively, are attached to the front side of the lid 3, and one of the electrodes 4 'is, for example, an electrical component. A positive current source is connected to the other electrode 5 ', and a negative current source is connected to the other electrode 5'. Although not shown in FIG. 1, the opening 2 ′ of the silver ion electrode casing 2 is provided.
On the other hand, on the back side of the lid 3, a male screw is formed which is screwed into the female screw of the opening 2 'of the silver ion electrode casing 2. Therefore, in order to attach the electrode to the silver ion electrode casing 2, it is only necessary to screw the male screw of the lid 3 into the female screw of the opening 2 ′ of the casing 2, and the electrode can be easily replaced together with the lid 3.

The cascade pump 10 is configured as a centrifugal pump having a number of blades. The second suction pipe 32 is connected to the suction port. A first discharge pipe 33 is connected to the discharge port. The ozone gas generator 15 is well known in the art, and its gas supply pipe 16 is opened at the center of the cascade pump 10 with a check valve 18 interposed. Therefore, when the ozone gas generator 15 is turned on while the cascade pump 10 is operating, the solenoid valve 19
Is opened, and the air supplied from the air supply pipe 17 and the ozone gas in which a part of the supplied air is ozonized are sucked into the negative pressure part in the cascade pump 10.

In the present embodiment, the gas-liquid separation device 20
It is composed of a hydrocyclone 21 having a conventionally known structure. The first discharge pipe 33 is tangentially connected to the body. Therefore, the first discharge pipe 33
Bath water supplied from is swirled in the liquid cyclo 21,
The bath water having a large specific gravity flows downward as an underflow, and the mixed gas of air and ozone gas having a small specific gravity flows upward as an overflow to separate gas and liquid. One end of the underflow pipe 22 of the liquid cyclo 21 is connected to a second discharge pipe 34 attached to the bathtub 30. Note that the liquid cyclone 21 is disposed at a position relatively higher than the bathtub 30, the circulation pipe system, and the like. Thereby, even when the cascade pump 10 stops and the hydrocyclone 21 does not operate, the bath water does not overflow.

The gas filter 25 has a container body, in which activated carbon is stored. The overflow port 26 of the liquid cyclone 21 is
Is connected. An exhaust pipe 27 is connected to an exhaust port of the container body.

Next, the operation of the above embodiment will be described. Although not specifically described, the superposed antibacterial device 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 a predetermined number of times a day or a week, the solenoid valve 60, the silver ion generator 1, the ozone gas generator 15 and the like are turned on, and the cascade pump 10 is started.
Then, the bath water in the bathtub 30 circulates in the circulation pipeline system. At this time, foreign substances such as human hair are removed from the hair catcher 50. In the silver ion generator 1, silver ions are mixed into the bath water. Thereby, various bacteria in the bath water are sterilized. Ozone gas is sucked into the negative pressure section of the cascade pump 10 together with air. The ozone gas containing air is strongly mixed into the bath water by the impeller of the cascade pump 10. 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.

Next, the bath water mixed with ozone gas is
It is pumped to the hydrocyclone 21. Liquid cyclone 21
The bath water is swirled in a known manner, so that the bath water having a large specific gravity and the gas having a small specific gravity are separated from each other.
Return to the bathtub 30 from 4. The gas reaches the gas filter 25 where the ozone gas is adsorbed and the air is released from the exhaust pipe 27 to the atmosphere. After a lapse of a predetermined time, that is, after a lapse of a time set so that the germs in the bath water are almost completely sterilized, the silver ion generator 1, the ozone gas generator 15, and the cascade pump 10 are turned off to end the sterilization. I do. Thereafter, sterilization is performed in the same manner. As described above, since the bacteria are sterilized almost completely for a relatively long time, the bacteria are sterilized on a day-by-day basis, but the propagation of various bacteria can be suppressed more than incomplete sterilization several times a day.

It is clear that the present invention can be implemented in various forms without being limited to the above embodiment. For example, it is apparent that the present invention can be performed without the gas-liquid separator 20, the gas filter 25, and the like. As described above, according to the present embodiment, the ozone gas is strongly mixed into the bath water by the impeller of the cascade pump 10 even without the gas-liquid separator 20, the gas filter 25, etc. A strong action such as action and decomposition action is obtained, and is reduced itself to dissolved oxygen. Therefore, the irritating odor peculiar to ozone gas is also eliminated. In addition, it is clear that an ejector can be interposed in the second suction pipe 32 and the gas supply pipe 16 can be opened at the throttle portion of the ejector. Further, a bypass pipe may be provided between the first discharge pipe 33 and the second discharge pipe 34 to bypass the liquid cyclo 21 so that the air is injected into the bathtub 30. At this time, the ozone gas generator 15 can be turned off. It is also clear that the silver ion generator 1, the ozone gas generator 15 and the like can be manually turned on and off at will. Further, a ceramic heater may be provided as a heater at an appropriate position in the circulation pipe system, and the ceramic heater may be controlled by a control device to keep the temperature of the bath water at a predetermined temperature and enjoy bathing at any time. . It is also apparent that a filtration device, an activation device, and the like, which the present applicant has proposed in Japanese Utility Model Application Laid-Open No. 6-48893 and the like, can be provided. Rajum ore can also be added to this activation device to provide a rajumu hot spring effect.

[0016]

As described above, according to the present invention, the antibacterial device interposed in the circulation line system includes a silver ion generator,
Combined with an ozone gas generator, the silver ion generator is interposed in the circulation pipe system so that the bath water flows through it, and the gas supply pipe of the ozone gas generator is connected to the negative pressure section of the circulation pipe system. Because it is open, that is, it is sterilized or antibacterial with two kinds of antibacterial elements, silver ions and ozone gas, so that it can be sterilized with a small amount of antibacterial elements compared to the case of sterilizing alone. An effect unique to the present invention can be obtained. At this time, effects such as decomposition and deodorization of an organic substance having a large molecular weight that bacteria cannot be decomposed by ozone gas are obtained. According to another invention, the gas supply pipe of the ozone gas generator is open to the negative pressure section inside the cascade pump, so that the ozone gas is strongly stirred with the bath water by the impeller of the cascade pump, and as a result, the reaction is stopped. Since it is promoted and reduced itself, even if the whole antibacterial device is installed in the bathroom, the irritating odor of ozone gas does not cover the bathroom.
