る。An embodiment of the present invention will be described below with reference to FIGS. The body 1 is detachably attached to the faucet 3 via the connecting portion 2. The body 1 has a central passage 1a in which a switching valve 4 is housed, and the faucet communication passage 1b is switched between the raw water discharge passage 1c and the inlet passage 1d for communication.
Cartridge 5 is removably attached to body 1. Cartridge 5 has a water inlet 5a and a water outlet 5 on its lower surface.
b. The water inlet 5a communicates with the inlet passage 1d of the body 1, and the water outlet 5b communicates with the purified water outlet passage 1e of the body 1. A hollow fiber membrane case 9 accommodating a hollow fiber membrane 6 is accommodated in the cartridge 5, and granular palm shell activated carbon 7 is accommodated around it. Perforated plates 10 and 11 are arranged so as to form the upper and lower end surfaces of the activated carbon 7. A check valve 8 is arranged between the activated carbon 7 and the water inlet 5a. The check valve 8 is attached to the water inlet 5 by its own weight.
It blocks a, and when water pressure is applied, it floats upward and water reaches the activated carbon 7 through the gap around it. Hollow fiber membrane 6 and activated carbon 7
The upper ends of the two substantially coincide with each other and are communicated with each other through the upper space 5c. Therefore, the hollow fiber membrane 6 has its upper end portion on the water inlet side. A transparent cap 5d is attached to the upper wall of the cartridge 5. The cap 5d has a concave shape. The hollow fiber membrane 6 is formed by bending at the upper end. A cover 12 is detachably attached to the body 1 so that the cartridge 5 is pressed against the body 1.

ことができる。In such a water purifier, if the switching valve 4 is set to the raw water side, the raw water can be taken out directly from the faucet 3 through the raw water discharge passage 1c. Further, when the switching valve 4 is set to the purified water side, the raw water passes from the faucet 3 through the inlet passage 1d to the water inlet 5a of the cartridge 5 and the check valve 8 is pressurized by water to float the activated carbon 7. After the chlorine odor and dirt have been adsorbed to the activated carbon 7 through it, the hollow fiber membrane 6 flows into the hollow fiber membrane 6 from the upper end side thereof to remove miscellaneous bacteria. You can take it out.
