PURPOSE:To certainly perform water-tight seal, by such a simple structure that the raw water port and the purification port of a water purifier are arranged so as to be capable of being changed over when raw water is supplied and respective water passages are held in a water-tight state through packings. CONSTITUTION:When tablewares are washed, a guide pipe 25 is withdrawn into a main body case 1 and a raw water port 30 is opposed to a suction port 7. When raw water is directly supplied in this state, a first packing 32 is contacted with the inner wall of a branched pipe 11 under pressure and raw water from the suction port 7 is prevented from leaking to a rear part opening 9. When purified water is obtained as drinking water, a knob member 5 is drawn out and raw water from the suction port 7 is guided to the rear part opening 9 of the branched pipe 11, a purification filter 45, the purificiation port 31 of the guide pipe 25 and a supply port 18. At this time, a communication passage is perfectly sealed by a second packing 33 and no short-circuit is generated.
