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, it has been required to enhance the sterilization function of the bathtub wall and the inside of the piping system.

[0004]

SUMMARY OF THE INVENTION The present invention is to effectively sterilize bacteria in such bath water and further inhabit the bathtub wall and the inside of the piping system, and enables 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 water in a bathtub and a pump for circulating water taken from the water intake section. And a purifying tank for purifying the water, a sterilizing device for sterilizing bacteria in the water, and a discharge unit for returning the treated water to the bathtub, and an ultraviolet sterilizing lamp and an electrolytic device as the sterilizing device. A hot water bath provided with a sterilizing device is provided, and preferably, an ultraviolet sterilizing lamp is provided after the electrolytic 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 an electrolytic device as a sterilizing device. By providing an electrolytic disinfection device in addition to the ultraviolet disinfection lamp, hypochlorite (hypochlorite ion) is mainly generated by the electrolysis device, and this is activated by irradiating it with ultraviolet rays or the like.

[0007] It is particularly preferable that an ultraviolet sterilizing lamp is installed after the electrolyzer, and the circuits for starting the electrolyzer and circulating the bath water at all times before and after the purification tank and the electrolyzer according to the respective purposes. The device is provided by bypass to the circuit. The reason why the ultraviolet germicidal lamp is preferably installed after the electrolysis device is that hypochlorous acid generated by electrolysis is activated by ultraviolet rays, and thus sterilization is performed effectively. And by constantly irradiating the circuit with an ultraviolet germicidal lamp, the bacteria brought in by the bather can be sterilized at all times. It is preferable that hypochlorous acid does not flow. This is because even the purified bacteria in the purification tank are sterilized by the sterilizing action of hypochlorous acid.

At the time of electrolysis, sodium chloride or the like present in the bath water is decomposed to generate chlorine ions. If the amount is insufficient, the salt is added to the bath water to dissolve it. It is preferable to generate a high concentration of hypochlorous acid. In addition, the electrolysis preferably has a long contact time with the electrode so as to generate a high concentration of hypochlorous acid, and the flow rate of bath water in the electrolysis tank is preferably low.
For this reason, the bypass connecting the electrolyzer is preferably provided with a valve so that the flow rate can be adjusted. Generally, the bypass is attached to the main circuit by a bypass having a small diameter.

[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. An electrolyzer (electrosterilizer) 9 is arranged in front of the ultraviolet sterilizing lamp 6. In particular, a bypass 10 is provided across the purification tank 5, and the electrolyzer 9 is connected to the main circuit by a bypass 11. In general, such an electrolyzer 9 applies a DC or AC voltage between opposing electrodes to electrolyze the salt of the bath water to produce hypochlorous acid, which is used for sterilization. .

In FIG. 1, when the electrolyzer 9 is not activated, the bypass 10 is closed. Therefore, the bath water taken from the water intake section 2 in the bathtub 1 is
The organic matter and the like in the purification tank 5 is decomposed to purify the bath water, the bacteria in the bath water are sterilized by the ultraviolet germicidal lamp 6, heated by the heater 7 and discharged from the discharge port 3 into the bath tub 1. It is returned to.

When sterilizing bacteria and the like that inhabit the wall surface of the bathtub or the inner wall of the piping system, the salt in the bath water is decomposed to obtain a product having a sterilizing ability. It is intended to deal with bacteria living on walls and the like. That is, when the electrolyzer 9 is started, the generated hypochlorous acid is activated by the ultraviolet lamp to increase the sterilizing ability, thereby sterilizing the above-mentioned bacteria and the like. The bypass 10 disposed before and after the tank 5 is released, that is, a valve provided before and after the bypass 10 prevents bath water from being introduced into the purification tank 5, and the product having a sterilizing ability is removed. The internal purification bacteria do not die without entering the purification tank 5.

[0012]

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.
