Abstract

A domestic appliance for ironing and/or steaming includes at least a first vaporization chamber and a second vaporization chamber arranged in a heating body containing at least one electric resistance, and a distribution circuit enabling a flow of steam to be conveyed from the second vaporization chamber to at least one steam outlet hole, the first vaporization chamber and the second vaporization chamber being positioned in series and connected to each other by at least one connecting duct, wherein the connecting duct is formed by a connecting tube inserted in the heating body, the connecting tube running in an area of the heating body heated by said at least one electrical resistance.

First claim

The invention claimed is:

1. A domestic appliance for ironing and/or steaming comprising at least a first vaporization chamber and a second vaporization chamber arranged in a heating body containing at least one electric resistance, and a distribution circuit configured to enable a flow of steam to be conveyed from the second vaporization chamber to at least one steam outlet hole, the first vaporization chamber and the second vaporization chamber being positioned in series and connected to each other by at least one connecting duct, wherein each of the at least one connecting duct is formed by a connecting tube inserted in the heating body, the connecting tube running in an area of the heating body heated by the at least one electrical resistance, and the connecting tube runs substantially along a longitudinal axis of the appliance.

2. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the connecting tube runs near said at least one electrical resistance.

3. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the connecting tube is made of stainless steel.

4. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the connecting tube extends near the center of the heating body.

5. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the heating body comprises an aluminum or magnesium casting.

6. The domestic appliance for ironing and/or steaming according to claim 5 , wherein the connecting tube is at least partially embedded in the casting.

7. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the connecting tube runs on the surface of the first vaporization chamber or of the second vaporization chamber.

8. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the second vaporization chamber extends to the perimeter of the first vaporization chamber ( 41 ).

9. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the heating body comprises a peripheral wall that delimits a space in which the first vaporization chamber and the second vaporization chamber are arranged, the peripheral wall extending from the bottom wall to a lid attached to the heating body.

10. The domestic appliance for ironing and/or steaming according to claim 9 , wherein the heating body comprises a partition wall that extends from the bottom wall to the lid and connects two opposite areas of the peripheral wall, the partition wall forming a separation between the first vaporization chamber and the second vaporization chamber.

11. The domestic appliance for ironing and/or steaming according to claim 10 , wherein the heating body comprises an inner wall that delimits, together with the partition wall, a flow channel for the steam flow inside the first vaporization chamber, the connecting tube comprising an inlet port that opens into said flow channel.

12. The domestic appliance for ironing and/or steaming according to claim 9 , wherein the lid comprises a water and/or steam injection port positioned facing an evaporation surface of the first vaporization chamber.

13. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the first vaporization chamber and the second vaporization chamber are connected to each other by two connecting tubes inserted in the heating body.

14. The domestic appliance for ironing and/or steaming according to claim 1 , wherein the connecting tube includes a first straight portion, a bent portion, and a second straight portion.

15. The domestic appliance of ironing and/or steaming according to claim 14 , wherein the bent portion is disposed between the first and the second straight portions.

16. A domestic appliance for ironing and/or steaming comprising at least a first vaporization chamber and a second vaporization chamber arranged in a heating body containing at least one electric resistance, and a distribution circuit configured to enable a flow of steam to be conveyed from the second vaporization chamber to at least one steam outlet hole, the first vaporization chamber and the second vaporization chamber being positioned in series and connected to each other by at least one connecting duct, wherein each of the at least one connecting duct is formed by a connecting tube inserted in the heating body, the connecting tube running in an area of the heating body heated by the at least one electrical resistance, and wherein the connecting tube runs on and along a surface of the first vaporization chamber or of the second vaporization chamber.
