しとることができる。The most common type of water purifier will be explained based on FIG. It includes an activated carbon layer 31 and a membrane 32 arranged in the water channel. The water first enters the activated carbon layer 31 to remove free chlorine. At the same time, defective components such as organic substances are taken into the activated carbon by adsorption. Water that has passed through the activated carbon layer 31 is taken out through the membrane 32 to the outside. This membrane 32
It has many pores of about 0.1 μm and can filter out germs.

ないものであった。Problems to be Solved by the Invention However, although the conventional water purifiers described above remove residual chlorine relatively well, they can only remove trihalomethane while the activated carbon layer is new. Furthermore, depending on the region, iron contains a very large amount of the mineral calcium (Ca), and when irons are used at home, there is a problem that the iron's steam holes become clogged. Conventional water purifiers have no effect on this mineral component, Ca.

Step 9 removes organic matter such as free chlorine and trihalomethane remaining in the water and sterilizes it. In this way, the water taken out to the outside through the photocatalytic reactor 29 is freely adjusted from water containing an appropriate amount of minerals that is optimal for drinking to pure water that is suitable for ironing.

Coal-based activated carbon or activated carbon fibers may be used, but here we used coconut shell activated carbon that has been thoroughly washed and adjusted to neutrality. The reverse osmosis membrane may be of cellulose acetate type, nylon type, polysulfone type, etc., but in this embodiment, a nylon type polyamide composite membrane is used. In this embodiment, limestone (CaCO) is used as the compound containing at least Ca. The semiconductor material constituting the photocatalytic reactor may be anatase-type titanium oxide, rutin-type titanium oxide, tungsten oxide, tin oxide, zinc oxide, or a mixture thereof, but in this example, platinum was added to anatase-type titanium oxide. I am using the attached one.

Note that since the removal of these substances is mainly through photocatalytic reactions, the ability is maintained for a longer period of time compared to conventional activated carbon adsorption methods. Furthermore, since the water of Sample 1 contained a large amount of Ca and almost all Mg, no steam clogging occurred in the iron. Sample 2 also contained a moderate amount of Ca, making it a healthy water.
