WATER PURIFIER

PURPOSE: To obtain high capacity even at low temperature by purifying raw water and storing purified water and also cooling the stored water by a thermoelectric semiconductor element before discharging the purified water to the outside and on the other hand, using the raw water while purifying it to absorb heat of the thermoelectric semiconductor element by a radiator. CONSTITUTION: Purified water 100 in the 1st stage used for cooling a heat sink 19 is caused to flow out of a radiator 11, and water temperature thereof is recognized by a temperature sensor 15 to feed it to the 2nd water purifying tan&c 3. At this time, the radiator 11 is used for cooling the heat sink 19, and heat is radiated from a Peltier element 10 to obtain a small-sized water purifier 1 causing no noise. After the purified water 100 is filtered by a hollow yarn membrane filter 3a and an active carbon filter 3b, it is fed into the 2nd water purifying tank 3 to turn it into purified water 200 in the 2nd stage, it is fed to the 3rd water purifying tank 4 and a branch line 70. Further, the 1st solenoid valve 25 is opened to discharge the purified water 200 from a discharge pipe 7, and also the 2nd solenoid valve 26 is opened to feed the purified water 200 to the 3rd water purifying tank 4.
