The purified water obtained by the above-mentioned process passes through the outlet 21, and the purified water enters the chamber 43 from the purification channel K through the water passage hole 58 and the water passage hole 49 communicating therewith. Subsequently, the purified water is discharged from the purified water discharge passage 31 to the faucet 29 through the water passage 52 and the water passage 54 communicating therewith. In addition, the cylinder 5
The raw hot water outlet channel 11 communicating with the third water hole 59 is shut off by the body of the movable valve 41.

The raw water flows out of the raw water outlet channel 11 into the chamber 43 through the water holes 59 and 51, flows through the purification channel K toward the outlet 21 through the water holes 50 and 58, and reaches the water purifier 1. Then, the cleaning cartridge is washed while flowing through the water purifier 1 in the opposite direction to the case of the raw water C, and hot water containing impurities flows in the raw water flow path 22 through the inlet 20 in the reverse direction, and the water holes 57, 47 are formed. And enters the room 42 via. Subsequently, the hot water containing the impurities is supplied to the impurity water discharge channel 2 through the water holes 48 and the water holes 55 communicating therewith.

に貢献できる。As described above, the water purification function for purifying the raw water passed through the undersink type water purifier and discharging the purified water, and the purification by the raw water passed from the opposite direction to the raw water. One switching lever is used to switch between a back-washing function that cleans the cartridge and discharge water adhering to the purification cartridge together with hot water and a water-stopping function that shuts off the flow path to the water purifier for both the raw water and raw water. The operation can be easily performed, and not only water purification but also cleaning of the purification cartridge can be performed, which can contribute to maintenance of the purification cartridge.
