業に好適に用いることができる。In the water purifier of the present invention, in addition to the water purification tank for obtaining purified water, the adsorbent for raw water is provided in the flow path that connects the water inlet and the raw water outlet. Thus, it is possible to selectively obtain purified water that has been subjected to adsorption filtration, and treated water from which the raw water adsorbent has removed mold odor, residual chlorine, etc. that cause odor and skin roughness. Further, since the raw water adsorbent is removably arranged in the flow path, if the raw water adsorbent has a reduced adsorption capacity due to long-term use of the water purifier, a new raw water adsorbent is used. It can be replaced with wood. Further, in the septic tank, for the purpose of removing not only mold odor and residual chlorine, but also bacteria and the like, for example, a filtration material composed of an adsorbent and a filtration film is stored. On the other hand, since only the raw water adsorbent is provided in the flow path that connects the water inlet and the raw water outlet, when water is passed through this flow path, compared with when water is passed through the water purification tank. Since the pressure loss is low, the treated water can be obtained at a discharge rate higher than that of normal purified water, and can be suitably used for cooking such as washing.

可能である。The raw water outlet may be a shower outlet and a straight outlet, and the raw water adsorbent may be arranged on the water inlet side of at least one of the shower outlet and the straight outlet. In this case, the adsorbent for raw water can be easily replaced by removing the caps of these outlets. Alternatively, it is also possible to provide a switching valve having a switching rotary shaft as a mechanism for switching the water discharged from the purified water outlet and the water discharged from the raw water outlet, and disposing the raw water adsorbent in the switching rotary shaft. In this case, the tap water sent to the clean water tank is also adsorbed by the raw water adsorbent before being sent to the clean water tank. Therefore, since the adsorbent for raw water plays a role of a prefilter of the water purification tank, the adsorption capacity of the water purifier can be improved. Alternatively, it is possible to reduce the amount of the adsorbent in the water purification tank and downsize the water purification tank.

It can be replaced with an adsorbent for raw water. Further, when the raw water outlet is composed of a shower outlet and a straight outlet, and the raw water adsorbent is arranged on the water inlet side of at least one of the shower outlet and the straight outlet, the raw water adsorbent can be easily replaced. . Alternatively, it is also possible to provide a switching valve having a switching rotary shaft as a mechanism for switching the water discharged from the purified water outlet and the water discharged from the raw water outlet, and disposing the raw water adsorbent in the switching rotary shaft. In this case, the tap water sent to the clean water tank is also adsorbed by the raw water adsorbent before being sent to the clean water tank. Therefore, since the adsorbent for raw water plays a role of a prefilter of the water purification tank, the adsorption capacity of the water purifier can be improved. Alternatively, it is possible to reduce the amount of the adsorbent in the water purification tank and downsize the water purification tank.
