都度交換可能なカートリッジ状となっている。These water purifiers include a water purifier main body comprising a raw water inlet, a water purifying outlet, and a flow path switching valve, and a filtration comprising an adsorbent such as activated carbon and a porous hollow fiber membrane. The water purifier main body is assumed to be used for a considerably long period of time, and the filtration unit is in a cartridge shape that can be replaced each time clogging due to purification occurs.

ない。[0006] Further, the faucet direct connection type water purifier is presumed to be used in a kitchen and is easily contaminated. Since most of the water purifier body is formed of plastic, the water purifier is repeatedly washed for removing dirt. In addition, dirt that cannot be completely removed is gradually deposited and the cleaning effect is reduced, and in addition to such adhesion of dirt, it is inevitable that tiredness is caused by long-term use.

Therefore, it is easy to make the whole water purifier liquid-tight. Water leakage due to pressurization during tap water purification processing and damage to the water purifier main body are unlikely to occur even with a material having a low mechanical strength and a water purifier main body structure. Further, it is only necessary to be able to withstand use for a relatively short period of time, and phenomena such as embrittlement of a used material and peeling of a potting portion are unlikely to occur.
