A brief description of the purifying member T2 is as follows.

jade;

Jade contains minerals, calcium, and magnesium that are extremely necessary for the human body, and magnesium accounts for more than 40% of its components, and magnesium is a component of chlorophyll. At the same time, the cells that make up our human body cells are also made of magnesium, so it is said that the Qi wave coming out of the jade and the Qi wave of the human body cells are the same wave. Therefore, the waves emitted from breathing jade evenly penetrate into our body cells and have a resonant resonance effect, thereby maintaining health through tissue resurrection, blood circulation, weak alkalinization of blood, and excretion of harmful wastes in the body. This is a unique effect that can

silicon;

Silicon is also called silicon. It has been known since ancient times as silicon oxide, SiO2, a relatively simple compound of silicon, and silica sand was also used as a raw material for glass production in ancient Egypt. In the natural world, it is not produced in a glass state, but exists as oxides and silicates, and is a major component of the lithosphere.

In the present invention, for example, a zeolite mineral containing silicon dioxide (SiO 2 ) as a main component is used. A mineral called zeolite is a porous mineral and has strong adsorption properties, so it adsorbs suspended matter well. As the zeolite, for example, a commercially available zeolite ball manufactured in a regular ball shape is used. However, it is not limited to that shape, and zeolite of any other shape can be used.

elvan;

Quartz Porphyry (麥飯石) is an ansan porphyry with a grayish white color. This name was given because the shape of the rock resembles a barley grain. The components of elvan are composed of Ge (germanium), SiO2, Al2O3, Fe2O3, CaO, MgO, K2O, NaO, TiO2, P2O5, MnO, TiO2, P2O5, MnO, etc. Because it is abundantly contained, its use is expanding day by day.

In modern times, research on the strong adsorption of elvan, precipitation of minerals, water quality control, and dissolved oxygen in water has been actively conducted, and has been actively used for food, cosmetics, toothpaste, fish farms, wastewater treatment, deodorant, plant growth promoter, medicinal medicine, and sauna facilities. It is used for manufacturing materials, far-infrared ray emitters, electromagnetic wave blockers, and building exterior materials.

yellow clay ball;

Loess, which covers about 10% of the land surface, contains large amounts of calcium carbonate (CaCo3). Due to this calcium carbonate, ocher has viscosity that is not easily broken and has the property of turning into clay when water is added. Ocher is composed of silica (SIO2), alumina (Al2O3), iron, magnesium (Mg), sodium (Na), and potassium. Ocher, composed of these ingredients and various enzymes, emits a large amount of far-infrared rays essential for the growth of animals and plants, so it is called a living organism. Loess has a honeycomb structure with a wide surface, and numerous spaces form a multi-layered structure. In this sponge-like hole, a large amount of far-infrared rays are absorbed and stored, and when heated, they are released and stimulate the molecular activity of other objects. In other words, ocher absorbs solar energy for many years, and as a siliceous mineral, it can be called a 'solar energy storage'. The enzymatic components of ocher include four types: catalase, diphenol oxidase, saccharase, and protease. These enzymes play the role of toxin removal, decomposition, fertilizer factor, and purification, respectively.

charcoal;

Charcoal has an infinite amount of negative ions generated from carbon. In places with a lot of negative ions, small water droplets adsorb pollutant particles around the waterfall and generate a lot of negative ions. Therefore, the effect of negative ions is as refreshing and fresh as the air in the forest, which naturally gives the body a sense of comfort. Negative ions are said to have effects such as blood purification, mental stability, autonomic nerve control, immunity enhancement, lung function enhancement, and cell activation. Charcoal also has purification, deodorization and filtering effects. If you put charcoal in the sewage, it absorbs ingredients such as pesticides and detergents in the sewage, so even a polluted river becomes a clean stream where meat swims if you fill it with charcoal on the bottom. Charcoal also has a far-infrared radiation effect. It also has the effect of adsorbing and removing harmful substances.

The branch opening/closing valves 50e and 50f are installed at positions where the water intake pipe 50 connected to the left double outer wall pipe 20l and the water intake pipe 50 connected to the central double outer wall pipe 20m communicate with each other. The valve 50e, the water intake pipe 50 connected to the central double outer wall pipe 20m and the water intake pipe 50 connected to the right double outer wall pipe 20r are connected to the fifth branch on/off valve 50f can be configured.

The present invention configured as described above has an effect of increasing washing efficiency because it is possible to selectively and intensively wash by controlling the first branch opening and closing valve 50b to the fifth branch opening and closing valve 50f.

On the other hand, except for the double outer wall pipe 20 whose filtration efficiency is lowered by the habitat of living things such as abalone and subduction, or by vomit, It is also possible to inhale, so there is an advantage of increasing the filtration efficiency.

It will be understood that such technical configuration of the present invention can be practiced by those skilled in the art to which the present invention belongs.

Therefore, the embodiments described above are illustrative in all respects and should be understood as non-limiting ones.
