The device and the method for forming steam are used for household appliance. Principle: water enters into the heated spiral tube chamber through the inner end of the spiral tube chamber; water contacts the side wall of the spiral tube chamber, and is vaporized, then diffused along the spiral tube chamber; part of the water droplets diffuses with vapor, and contacts the side wall of the spiral tube chamber gradually, then is vaporized; vapor is obtained from the outer end of the spiral tube chamber. In one word, the invention provides a method to obtain “dry” steam which doesn't contain water. It is more efficient than other facilities.
