PCT No. PCT/SE96/00817 Sec. 371 Date Dec. 15, 1997 Sec. 102(e) Date Dec. 15, 1997 PCT Filed Jun. 24, 1996 PCT Pub. No. WO97/00831 PCT Pub. Date Jan. 9, 1997A device for mixing air and water in a water purifier comprises a water inlet pipe (3), which is connected to a water source and extends into a water purifier tank (2), and an air inlet pipe (6) extending coaxially inside the water pipe. One end of the air pipe is positioned outside the tank and the other end is positioned inside the water pipe to form an annular gap (8) between the end (7) of the air pipe and the inner wall of the water pipe. The water pipe has a mixing portion (9, 13) extending from the annular gap (8) to the mouth of the water pipe in the tank. In the mixing portion there is at least one ring (10-12) arranged on the inside of the water pipe and being hit by an annular water jet formed as the water passes through the gap (8), thereby forcing the water to mix with the air.
