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.

I claim: 1. A device for forming steam for household appliance, comprising: a spiral tube chamber, a heating unit comprising a heating element which is set on the outside of spiral tube chamber, a water intake which is on the inner end of the spiral tube chamber, and a steam outlet which is at the outer end of the spiral tube chamber, wherein the spiral tube chamber is on the heating unit, wherein the heating element is an electric heating element, which is buried in the body of the heating unit, and constitutes the heating facility, and wherein the heating unit comprises: a main body, a cover plate set on the top of the main body of the heating unit, two spiral grooves, which are respectively set on the opposite face of the cover plate and the main body of the heating unit, forming the spiral tube chamber, the electric heating element being buried in the main body of the heating unit, a water intake on the upper surface of the cover plate facing the inner end of the spiral groove, and a steam outlet on the upper surface of the cover plate facing to the outer end of the spiral groove. 2. A device for forming steam for household appliance, comprising: a spiral tube chamber, a heating unit comprising a heating element which is set on the outside of spiral tube chamber, a water intake which is on the inner end of the spiral tube chamber, and a steam outlet which is at the outer end of the spiral tube chamber, wherein the spiral tube chamber is on the heating unit, wherein the heating element is an electric heating element, which is buried in the body of the heating unit, and constitutes the heating facility, and wherein the heating unit comprises: a main body; a upper cover plate which is located on the top of the main body of the heating unit; a lower cover plate which is located on the bottom of the main body of the heating unit; a first spiral groove, which is machined on top of the main body of the heating unit, constituting the first spiral tube chamber enclosed within the lower surface of the upper cover plate; a second spiral groove, which is machined on the bottom of the main body of the heating unit, constituting the second spiral tube chamber enclosed with the upper surface of the lower cover plate; a heating element buried in the main body of the heating unit; two inner ends of the first spiral tube chamber and the second spiral tube chamber connecting with each other; a water intake on the top of the upper cover plate facing the inner end of the spiral tube chamber; and a steam outlet on the side wall of the main body of the heating unit facing the outer end of two spiral grooves. 3. The device for forming steam for household appliance of claim 1, wherein a sealing washer is provided between the main body of the heating unit and the cover plate. 4. The device for forming steam for household appliance of claim 2, wherein the spiral tube chamber is formed on a soleplate of iron, wherein the electric heating element is buried in the soleplate and constitutes the heating facility; wherein the spiral groove is formed on the upper surface of the soleplate and constitutes the spiral tube chamber enclosed within the cover plate which is located on the top of the spiral groove; wherein the water intake is formed on the upper surface of the cover plate facing the inner end of the spiral tube chamber; and wherein the steam outlet is formed on the lower surface of the soleplate facing the outer end of the spiral tube chamber. 5. The device for forming steam for household appliance of claim 2, wherein the cross section of the spiral tube chamber is circular. 6. The device for forming steam for household appliance of claim 2, wherein the cross sections of the first spiral tube chamber and the second spiral tube chamber are rectangular. 7. The device for forming steam for household appliance of claim 2, wherein sealing washers are provided between the upper cover plate, the lower cover plate and the main body of the heating unit separately.
