Abstract

PROBLEM TO BE SOLVED: To destroy the bacteria in bathing water to keep bathing water clean to prevent infection of bacteria even in the case of a number of people bathing for rehabilitation by incorporating a sterilizing means in a circulating pipeline for connecting a circulating pump for bathing water, a bathing water suction port, an air intake port, an air mixing part, and a discharge port to one another. SOLUTION: A bath tub 1, a bathing water suction port 2, a pre-filter 3, a circulating pump 4, an air intake port 5 an air mixing part 6 and a discharge port 7 are connected to one another by a circulating pipeline 8, and various kinds of sterilizing means 9 are incorporated in the pipeline. That is, the sterilizing means 9 is formed by an ozone generator 10, and plural ultraviolet lamps 11, 12. The ozone generator 10 takes air in an ozonizer and guides the generated ozone into the circulating pipeline 8 by an ejector. The ultraviolet lamp 11 generates ultraviolet rays with about 200-300 nm by a low-pressure mercury-arc lamp to irradiate dissolved ozone in bathing water. Further, the ultraviolet lamp 12 generates ultraviolet rays with about 300-420 nm by a black light to promote irradiation, thereby intensifying the sterilizing force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet bath having a sterilizing function in bath water.

[0002]

2. Description of the Related Art A conventional jet bath is composed of a circulating pump, a bath water inlet, an air inlet, an air mixing section, a discharge port, and a circulation line, but has no function of sterilizing bath water.
Therefore, when bacteria were brought in by bathers, they sometimes proliferated inside the bathtub.

As means for keeping bath water clean, so-called 2
There are cases where baths are used side by side in a bathtub for 4 hours,
The purification function is usually based on biological purification, and in addition to the purification bacteria, there is a risk of propagation of the harmful pathogenic bacteria as described above, which may result in unfavorable hygiene.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above prior art, and has as its object to provide a jet bath for disinfecting bacteria in bath water by incorporating disinfecting means.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a jet bath having a circulation pump for bath water, a suction inlet for bath water, an air intake, an air mixing section, a discharge port, and a circulation pipe connecting these. In addition, the present invention relates to a jet bath characterized by incorporating sterilizing means in a circulation pipe, and particularly, the sterilizing means used is an ultraviolet sterilizing lamp and / or an ozone generator, and And a black light. Furthermore, the germicidal means used is a jet bath which is either an electrolytic sterilizer, a ceramic material that elutes silver ions, or a chlorine-adding device.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The sterilizing means employed in the present invention is preferably an ultraviolet sterilizing lamp. The sterilizing effect is ensured by setting the irradiation amount to 6 mW · sec / cm ² or more. In some cases, the flow rate passing through the sterilizer is adjusted by a branch pipe or the like so as to be an appropriate amount.

An ozone generator as a sterilizing means takes air into an ozone generator and converts oxygen in the air into ozone. However, if ozone molecules are dissolved as much as possible in the bath water, the ozone generator disinfects the bathtub wall by its sterilizing power. And the inside of the plumber is sterilized.

The sterilizing effect of ultraviolet rays is enhanced by combination with ozone, and the self-decomposition of ozone is promoted by irradiating the ozone molecules generated from the ozone generator with ultraviolet rays having a wavelength of 200 to 300 nm. Then, the following reaction occurs. (Reaction 1) O ₃ → O ₂ + O, (Reaction
^{2) O (1 D) +} H 2 O → 2 · OH, ( reaction · ₃₎ O 3
+ H ₂ O → O ₂ + H ₂ O ₂ , (Reaction 4) H ₂ O ₂ → 2
・ OH

Incidentally, O ( ¹ D) is singlet active oxygen, and .OH is a hydroxy radical. These hydroxy radicals show stronger bactericidal activity than when used with ozone alone and UV alone. Further, by irradiating ultraviolet rays having a wavelength of 300 to 420 nm in combination with a black light, Reaction 2 is promoted, and a large amount of hydroxy radicals is generated.

[0010] In electrolytic sterilization, chloride ions dissolved in the bath water by electrolysis of the bath water - at the anode from ^(CL) (CLO ^-) ions are generated, the (CLOs ^-) 0 ions in the bath water It shows a bactericidal action by eluting about 0.5 PPM. The effect of the electrolysis of bath water is different depending on the time the bath water exists between the charged electrodes. Therefore, a branch pipe having a smaller flow rate than the circulation pipe is provided. Preferably, a tank is provided.

Further, by bringing a ceramic material (e.g., zeolite or silica gel) capable of eluting silver ions into contact with bath water, silver ions can be eluted into the bath water in trace amounts over a long period of time. Sterilization is performed by the sterilizing power of the silver ions.

[0012] Further, by automatically intermittently adding a liquid sodium hypochlorite, a solid sodium dichloroisocyanurate, trichloroisocyanuric acid, sodium hypochlorite, etc., to the bath water, these chemicals are removed. resulting (CLOs ^-) by ion, bactericidal effect is exhibited.

According to the present invention, the inside of the bathtub can always be kept in a sterilized state by using the above sterilizing means appropriately alone or in combination.

Usually, air is taken into an ozonizer through an electromagnetic valve from an air pump, and the generated ozone is guided into the circulation line 8 by an ejector through a check valve.

Next, ultraviolet rays of 200 to 300 nm are generated by an ultraviolet lamp (a) 11, for example, a low-pressure mercury lamp, and the dissolved ozone in the bath water is irradiated.
12, for example, a black light is used to generate 300 to 420 nm ultraviolet rays and further irradiate them to enhance the sterilizing power. The sterilizing means 9 may be provided in a branch pipe (not shown) branched from the circulation path 8.
