DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chlorine removing apparatus for removing chlorine contained in tap water of ordinary households.

[0002]

2. Description of the Related Art Generally, tap water used at home contains a large amount of chlorine for sterilization. Since the action of disinfection by mixing chlorine is carried out by the strong oxidizing action of hypochlorous acid obtained by the direct reaction of chlorine gas and water, for example, tap water is used as washing water for an anal washer or water for a washing machine. When used, it may cause damage by contacting whole body skin cells with a specific constitution such as an anus or atopic nature of the human body. Therefore, in the anal washer, a chlorine removing device for detoxifying tap water as washing water that can be directly contacted with the human body is disclosed in, for example, Japanese Patent Application Laid-Open No. H8-208.
No. 197 075.

[0003] As shown in FIG. 7, the chlorine removing apparatus is provided with a small-diameter throat 102 in the middle of a main pipe 101 connected to a water pipe.

A spiral strip 107 is provided between the throat 102 and the outflow pipe 105, and a part of the running water flowing through the main pipe 101 is encapsulated from the inflow pipe 104 by a pressure difference between the pressure immediately before the throat 102 and the throat 102. 103, comes into contact with calcium sulfite, deprives the chlorine radicals by a reducing action and becomes harmless water, and the harmless water flows into the throat portion 102 from the outlet pipe 105 and directly from the main pipe 101 to the throat portion 102. The water is mixed with the water that has flowed into the water, and is stirred by the spiral strip 107 so as to become washing water.

[0004]

However, in such a chlorine removing apparatus, most of the flowing water in the main pipe 101 is not treated in the capsule 103, and most of the water flows from the main pipe 101 into the throat section 102 as it is. The detoxified water that has been treated in the capsule 103 and flowed into the throat 102 from the outflow pipe 105 is mixed, so that a large amount of untreated water that does not remove chlorine is mixed, and the washing water still contains chlorine. However, there is a problem that the detoxifying effect of water is not sufficient. In addition, there is a problem that the structure becomes complicated, such as providing an inflow pipe and an outflow pipe, which complicates the production and increases the cost. Therefore, the present invention has been made to solve such problems in the conventional technology, and can sufficiently achieve the detoxification effect of water, can easily replace the filter cartridge, and has a simple structure. It is an object of the present invention to provide a chlorine removing apparatus which can be manufactured in a country.
