The present invention relates to a device for cleaning and sterilizing circulation of bath water, in which the bath water is appropriately heated and purified.

[0002]

2. Description of the Related Art As is well known, home baths used in Japan are generally classified into a reheating type and a dropping type. That is, the reheating type bath is composed of a bathtub and a heater, and the bath water is naturally circulated between the heater and the bath to be heated.

On the other hand, the drop-in bath, which has recently become popular, is designed to pour hot water of a predetermined temperature into a bathtub from, for example, a water heater or a hot water storage tank. These methods include
There are merits and demerits, and if either method is superior, immediate judgment cannot be made. For example, in a drop-in bath, hot water at a predetermined temperature is poured as appropriate, so that the advantage of the bath water being 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 appropriately heated while being circulated, so that it is not necessary to add high-temperature hot water as in the drop-in bath.
It has the economic advantage that you can take the same hot water many times,
It is suitable as a bath where you can enjoy bathing at any time. However, as the number of baths increases, the hot water becomes
It is contaminated with human hair and other bacteria also proliferate, making it unsuitable for bathing. Therefore, a bath water purifying device has been proposed, for example, in Japanese Patent Publication No. 57-17564. The purification device disclosed in the above publication includes a pump for forcibly circulating hot water, a filter, and a water activated filtration device. Therefore, when the pump is activated to circulate the hot water, the hot 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, Japanese Patent Application Laid-Open No. 54-72164 proposes a hot water purifying device in a bathtub. The device includes an inner nonwoven fabric, an outer nonwoven fabric, and an air escape pipe. Therefore the bath water is filtered with this non-woven fabric,
The air that separates from the water during filtration is exhausted by a pipe.

[0006]

Since the above-mentioned bath water purifying device also has a filter, human hair, dirt, dust, etc. are removed from the bath water, and an activating device is also provided. Will be purified for the time being. However, since there is a problem with the structure of the filter and no consideration is given to odors, microorganisms, etc. that cannot be collected by the filter, there is a problem in this respect as well. That is, the filter has a tubular shape and the inside thereof is filled with the filter cloth, but the filter area is small and there is a possibility that clogging may occur at an early stage. In addition, since microorganisms that are not removed by the filter keep the hot water at an appropriate temperature, they may proliferate well 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. However, it is possible to neutralize the bad odor by mixing a bath additive etc., but 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 in hygiene, so it must be discarded after all, and the bath water cannot be used repeatedly for a long period of time. When hot water is discarded and newly poured, it requires a large amount of energy to heat up to a temperature suitable for bathing, and there is a problem of wasting water.

On the other hand, the hot water purifying apparatus described in Japanese Patent Laid-Open No. 54-72164 has an inner nonwoven fabric, an outer nonwoven fabric, and an air escape pipe, so that part of the hot water is filtered by the inner nonwoven fabric. The rest is filtered with the outer nonwoven fabric and the wire mesh of the air escape pipe. However, there is a problem in the structure of the air escape pipe, and the wire mesh of the air escape pipe is also filtered, so that the wire mesh may be clogged early. If clogging occurs, air will not escape and will accumulate in the upper space of the tubular body. When air accumulates, bacteria inhabit in this part, for example, assimilating CO ₂ and converting it into organic matter, and spoiling the hot water.

Further, since the above hot water purification apparatus is equipped with a sterilizing ultraviolet lamp, even if there is no problem with respect to sterilization, no measures are taken against the odor, activation, etc. of the hot water, so it cannot be used repeatedly for a long period of time It is a thing. Therefore, the present invention provides a bath water cleansing and sterilizing circulation device which is more thoroughly filtered and cleanly cleaned, and more sanitarily sterilized and deodorized so that the bath water can be repeatedly used for a long period of time. Is intended.

[0009]

In order to achieve the above-mentioned object, the present invention has a filter, a circulation pump, an activation tank, and a heater connected by a circulation pipe, and a suction portion of the circulation pipe. When the circulation pump is driven, the bath water circulates among the bath, the filtration tank, the circulation pump, the activation tank, and the heater, and ozone is discharged between them. A circulation device adapted to appropriately inject ozone from a generator and to be heated to a temperature set by a control device, the filter device, the circulation pump, the heater, the activation tank, and the ozone generator. , At least the filtration device, the activation tank, and the ozone generator are housed in a container, and the filtration device is arranged so that an internal space is formed in the filtration tank. With a filtering layer An air intake pipe for evacuating air from the internal space, an inlet pipe for supplying bath hot water to be filtered to the side wall of the filtration tank, and a filtered bath at a substantially central portion of the bottom wall. A discharge pipe for discharging hot water is provided, and the intake pipe has an upper portion open to an upper portion of an internal space formed by the filtration layer,
The lower part thereof faces the outlet pipe, the activated tank is filled with activated stones, the lower part of the tank is provided with an entrance of activated hot water, and the upper part is provided with the activated hot water. And an ozone suction / injection pipe for mixing ozone generated from the ozone generator into the bath water is configured to open in the circulation pipe of the bath.

[0010]

Since the present invention is constructed as described above,
When the circulation pump is activated, the bath water circulates between the bathtubs by the circulation pipe, and at this time, it passes through the filtration device, the circulation pump, the activation tank, the heater, and the like. When circulating in this way, in the filtration device, the bath water enters the filtration tank from the introduction pipe provided on the side wall, is filtered by the filtration layer, and is filtered from the internal space formed by the filtration layer to the bottom wall of the filtration tank. Go out from the outlet pipe in the approximate center of. At this time, the air accumulated in the internal space is exhausted from the intake pipe together with the bath water. Since the lower part of the intake pipe faces the inside of the outlet pipe, the outlet pipe is in a squeezed state and negative pressure is generated by the circulating bath water, so that air is effectively sucked and discharged.

Since the activation tank is filled with activated stones such as barley stone, hot water decomposes bacteria, ie, organic substances, which propagate as activated stones and carry out other nourishment when passing through the activation tank. Bacteria, which obtain the energy of life, cleanse the bath water by decomposing organic substances such as ammonya, which causes the bath water to rot. Further, the hot water is ion-exchanged, and active ingredients such as magnesium, zinc, calcium, and sodium are dissolved in the hot water, and the hydrogen ion concentration of the hot water is adjusted to be weakly alkaline. This imparts a bathing effect to the bath water. Ozone is injected into the bath water discharged from the active tank by the ozone suction / intake pipe, and the ozone is reduced to oxygen. When it is reduced to oxygen, microorganisms and the like in the bath water are sterilized and deodorized, and organic substances having a large molecular weight are decomposed into organic substances having a small molecular weight.
As described above, 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. First,
As shown in FIG. 2, the device casing 1 has a substantially cubic shape,
A filtration tank 4 that constitutes a filtration device inside this, a circulation pump 5 that circulates the hot water, a heater 6 that appropriately heats the hot water, an activation tank 7 that purifies the hot water, and ozone generation. A device 8 is provided. The filtration tank 4, the activation tank 7, and the ozone generator 8 are provided in the container 1
It is attached to the upper wall plate of and is suspended in the container 1.

The filtration device is roughly composed of a cylindrical filtration tank 4, a filtration layer 10 concentrically arranged inside the filtration tank 4, and an intake pipe 13. An inlet pipe 9 for guiding the bath water to be filtered to the filtration tank 4 is connected to the side wall of the tubular filtration tank 4, and a discharge pipe 11 for discharging the filtered bath water is connected to the filtration tank 4 Is provided in the approximate center of the bottom wall of the. These inlet pipe 9 and outlet pipe 11 form a part of a circulation pipe.

The intake pipe 13 is arranged in the internal space formed by the filtration layer 10, and the upper portion 12 thereof is open to the upper portion of this internal space. Further, the lower portion has a tapered diameter, and the diameter-enlarged portion extends to the inside of the lead-out pipe 11. The circulation pump 5 driven by the motor 14 is
It is arranged near the bottom wall of the container case 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. The reference numeral 15 indicates a drain port.

The heater 6 is composed of a heater 16. The purification and sterilization circulation device of the illustrated embodiment is provided with a power supply control unit 25, and is also provided with a control device for switching between automatic and manual operation, and setting and displaying the temperature of the bath water. The activation tank 7 also has a tubular shape as shown in FIG. 1, and the inside thereof is filled with an activated stone 18 such as barley stone.
The hot water to be treated is introduced from the lower side of the activation tank 7, and the purified hot water flows out from the upper side. A circulation pump 5 and an activation tank 7 are provided in the housing 1.
The ozone generator 8 is stored in the same manner as the above. The ozone generator 8 includes an ozone generator 20, a high-pressure transformer 21, and an air pump 22, and an end of an ozone suction / injection pipe 23 connected to the ozone generator 20 connects the activation tank 7 and the bath a. It is open to the reflux pipe 19 which is a part of the circulation pipe to be connected.

Next, the operation of the above embodiment will be described.
First, the power supply controller 25 is turned on. And the control device 2
4. Set the hot water temperature automatically, for example, and set the circulation pump 5
To start. 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 from 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. From the internal space formed by (3), the outlet pipe 11 is provided 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 pipe 13. Since the tapered lower diameter portion of the intake pipe 13 faces the outlet pipe 11, the outlet pipe 11
Becomes a squeezed state, a negative pressure is generated by the circulating bath water, and the air is effectively sucked and discharged.

If air is not sufficiently discharged and is accumulated in the inner space, that is, if air is accumulated in the upper portion of the inner space formed by the filter tank 10, the portion where the air is accumulated does not contribute to the filtration. As a result, the filtration area becomes smaller 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, so that the bath water is spoiled. However, according to this embodiment, the air in the internal space is discharged from the intake pipe 13, so that the above-mentioned problem does not occur. Moreover, even if the bath water is discharged from the intake pipe 13 together with the air, since the bath water is filtered by the filter layer 10, the intake pipe 13 will not be clogged with human hair, dirt or the like.

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 it flows uniformly in the activated stone 18,
The activated stone 18 is effectively used without causing a short circuit. The bath water discharged from the activation tank 7 is the reflux pipe 19
Then, the ozone from the ozone generator 20 is appropriately injected into the bath water by the air pump 22 at this time, and the bath water is sterilized, deodorized, and decomposed with organic substances.

According to the present embodiment, as described above, it is filtered by the filter device, purified by the activated stone 18, and sterilized and deodorized by ozone, so that the bath water is purified to a level suitable for drinks. To be done. This is 2 of the Japan Food Analysis Center, located in Motoyoyogi-cho, Shibuya-ku, Tokyo.
It was proved by the analysis results of the baths used for a week, and the social welfare corporation Cross Society (Setagaya-ku, Tokyo) averaged 11 days a day.
It was also proved by the analysis results of 0 people and 2 people who requested a continuous bathing bath in February from the Tokyo Metropolitan Institute of Public Health (3-24-1, Hyakunincho, Shinjuku-ku).

[0020]

As described above, according to the present invention, the filtration device, the circulation pump, the activation tank, and the heater are connected by the circulation pipe, and the suction portion and the discharge portion of the circulation pipe are connected to the bathtub. When the circulation pump is driven, the bath water turns into a bathtub.
The bath is circulated between the filtration tank, the circulation pump, the activation tank, and the heater, and ozone is appropriately injected from the ozone generator during that period, so that the bath water is filtered more completely. It is more purified, sanitized and deodorized more hygienically, and as a result, it can be repeatedly used for a long period of time without changing the bath water. In particular, if air is formed in the upper part of the internal space formed by the filter layer, the part where the air is collected does not contribute to the filtration, and as a result, the filtration area is reduced, the filtration capacity is reduced, and the circulation pump Although the load will be large, and various bacteria will inhabit the air part, and it will also spoil the bath water.However, according to the present invention, the air in the internal space is exhausted from the intake pipe. Such a problem does not occur. Moreover, even when the hot water is discharged from the intake pipe, the hot water is filtered by the filter layer, so that the intake pipe will not be clogged with human hair or dirt. Also, when hot water passes through the activation tank, the bacteria that propagate to activated stones and carry out other nourishment, that is, the organic matter that decomposes organic matter and obtains energy for life, cause the organic matter, for example, the bath water, to decompose. To decompose the bath water and purify it. Further, the hot water is ion-exchanged and the active ingredients such as magnesium, zinc, calcium and sodium are dissolved in the hot water, and the hydrogen ion concentration of the hot water is adjusted to be weakly alkaline. This imparts a bathing effect to the bath water. Furthermore, the ozone gas is reduced to oxygen in the bath water, becomes dissolved oxygen, and assists the growth of aerobic bacteria living in the activation device, and further promotes the purification of the bath water by the aerobic bacteria. When ozone gas is reduced, bacteria in the hot water are sterilized, deodorized, and decomposition of organic matter such as scales is promoted. In addition, according to the present invention, since the filtration device, the circulation pump, the activation tank, the heater, and the ozone generator for supplying ozone into the bath water are housed in the vessel casing, It has the effect that it can be set in the right place and is easy to use.
