Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warm water bath for circulating bath water by removing water in a bath tub, purifying the water in a purification tank, sterilizing it with a sterilizing device, returning it to the bath tub again and circulating the bath water. is there.

[0002]

2. Description of the Related Art In recent years, bath water in a bathtub has been purified with a purifying material,
Hot water baths, which are returned to the bathtub and always used, have come to be used at home. A normal hot water bath has a heating means for maintaining a constant temperature, a pre-filter for removing large solids such as hair and dust, and secretions from the body in the bath water (amino acids, protein, etc. contained in body fluids). It consists of a purifying tank that removes foreign substances such as skin that has been converted into water, and a sterilizing device for bacteria in the bath water such as ultraviolet rays and ozone, so that you can take a bath at any time without changing the bath water every day. It is convenient and can save water.

[0003] The mechanism for purifying the water quality of this warm bath is considered as follows. That is, coarse dust such as hair is removed from a pre-filter made of urethane foam or the like.
(Hair-catcher), and the secretions from the body in the bath water are purified in a purification tank. In other words, the purification tank contains granular ceramics such as those obtained by crushing barley stone, natural stone, etc. and sintering them in a porous state. The bath water is purified because microorganisms eat and decompose ammonia and proteins contained in the bath water as food.
Then, bacteria derived from the body taking a bath are sterilized by a sterilizer such as ultraviolet rays and ozone. However, in recent years, in order to enable long-term use of bath water, there has been a demand for enhanced sterilization of the bathtub wall and the inside of the piping system.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to effectively sterilize bacteria living in such bath water and further inhabiting the bathtub wall and the inside of the piping system, thereby enabling use of the bath water for a long time. It is intended to provide a warm bath.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the present invention is to provide a water intake section for taking in water in a bathtub, a pump for taking water from the water intake section and circulating water, and a pump. A hot water bath equipped with a purification tank for purifying water, a disinfection device for disinfecting bacteria in the water, and a discharge unit for returning the purified and disinfected water to the bathtub. The present invention relates to a warm bath equipped with an agent charging device.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a warm bath as described above, which is provided with an ultraviolet germicidal lamp and a chlorinator charging device as a sterilizing device. In addition to the ultraviolet germicidal lamp, an apparatus for introducing a chlorine agent is added, and sterilization of the bathtub wall and the inside of the piping system is performed using hypochlorous acid generated by the introduction of the chlorine agent. Chlorine injection is equipped with a switching valve,
The required amount will be appropriately poured into the bath water.

[0007] It is particularly preferable that an ultraviolet sterilizing lamp is installed after the chlorine-supplying device. A bypass circuit is provided before and after the chlorinating agent charging device. The reason that the ultraviolet sterilizing lamp is preferably installed after the chlorine agent injection device is that the injected chlorine agent is activated by ultraviolet rays and is decomposed at an early stage, and is effectively sterilized. Contact time can be made as short as possible. Then, by constantly irradiating the circuit with an ultraviolet sterilizing lamp, bacteria brought in by the bather can be always sterilized. Further, when the chlorinating agent is supplied, it is preferable to close the bypass circuits before and after the purification tank so that the chlorinating agent does not flow into the purification column. This is to prevent as much as possible sterilization of the purified bacteria in the cleaning cylinder by the sterilizing action of the chlorine agent.

As the chlorine agent to be used, sodium dichloroisocyanurate, trichloroisocyanuric acid, sodium hypochlorite and calcium hypochlorite are used. Sodium dichloroisocyanurate is used as an inorganic salt or a blowing agent. It is mixed and used as a tablet or powder, and sodium hypochlorite is preferably used as a 1 to 14% aqueous solution. In particular, since trichlorisocyanuric acid tablets have low solubility, by using this,
It is possible to provide a chlorinating agent sterilizer that gradually dissolves it while contacting with water, which makes it relatively easy to input and replace chlorine.

[0009]

EXAMPLES Hereinafter, the warm bath of the present invention will be described in more detail with reference to examples. FIG. 1 is an overall view showing a preferred example of a warm water bath of the present invention. First, a water bath 2 and a discharge unit 3 are provided in bath water in a bathtub 1. And the hot water bath body 20
Inside are a pump 4, a purification tank 5, an ultraviolet germicidal lamp 6,
Necessary components such as a filter 7 are provided.
It is connected by. Further, a chlorine injection device 9 is disposed in front of the ultraviolet sterilizing lamp 6. In particular, a bypass 10 is provided with the purification tank 5 interposed therebetween, and a bypass 11 is further provided with the chlorine input device 9 interposed therebetween.

Although the chlorinator 9 is not particularly limited, FIG. 2 shows an example of the chlorinator, and some openings (holes) 1 for the tablet 11 to contact the bath water with respect to the bypass 11.
The cartridge 12 is provided with a medicine cartridge 12 having a chlorine tablet 15 filled therein and a spring 13 for pressing the tablet. The chlorine tablet 15 which gradually dissolves is supplied for a long period of time. still,
When the chlorinating agent is charged, the bypass 11 is closed, and the bath water flows through the chlorinating agent charging device.

In FIG. 1, when the chlorinating agent is not charged, the bypass 10 is closed, the bypass 11 is released and the hot tub is operated, and the bath water in the bath tub 1 is taken in from the water intake section 2 and purified. Organic matter and the like in the bath water is decomposed in the tank 5 to purify the bath water, bacteria in the bath water are sterilized by the ultraviolet germicidal lamp 6, heated by the heater 7 and heated from the discharge port 3 to the bath tub 1. It will be returned inside.

When sterilizing bacteria that inhabit the bathtub wall surface or the piping system inner wall surface, a chlorine agent is put into the bath water to deal with these bacteria. The bypass 10 is released and the bypass 11
Is operated in a closed state. In other words, when a chlorinating agent is injected into the circuit, the chlorinating agent in the bath water is activated by an ultraviolet lamp, and the bacteria in the bath water disinfect the bacteria that inhabit the bathtub wall and the inner wall of the piping system. It is. When the bypass 10 is released, that is, when the valves at both ends of the bypass 10 are closed, the chlorine-containing agent does not enter the purification tank 5 and the internal purification bacteria do not die.

[0013]

According to the hot water bath of the present invention, not only bacteria in the bath water but also bacteria living in the bathtub wall and the inside of the piping system can be effectively sterilized. It provides a safer hot water bath for long-term use.
