Abstract

A smoothing head includes a steam distribution circuit containing an inlet duct including an inlet opening connected to a steam pipe; and a front wall equipped with a treatment face including at least one steam outlet hole and intended to face a garment to be smoothed. The inlet duct includes an outlet opening leading to an inner chamber belonging to the steam distribution circuit, the inner chamber including a condensate evacuation opening communicating with a condensate return circuit leading to the steam pipe or to the inlet duct.

First claim

The invention claimed is:

1. A smoothing head comprising a steam distribution circuit and a front wall equipped with a treatment face intended to face a garment to be smoothed, the treatment face comprising at least one steam outlet hole, the steam distribution circuit comprising an inlet duct including an inlet opening intended to be connected to a steam pipe, the steam distribution circuit also comprising an inner chamber, the inlet duct comprising an outlet opening leading to the inner chamber, the inner chamber comprising a condensate evacuation opening communicating with a condensate return circuit, wherein the condensate return circuit is configured to lead to the steam pipe or to the inlet duct, and
wherein the smoothing head further comprises a partition wall extending parallel to the front wall configured so as to direct steam emitting from the outlet opening of the inlet duct along the front wall prior to entering the at least one steam outlet hole,
wherein the inlet duct has a 90° elbow upstream of the outlet opening, and
wherein the elbow has an inner bend radius of between 3.5 and 4.5 mm and an outer bend radius of between 9 and 11 mm.

2. The smoothing head according to claim 1 , wherein the outlet opening leads to an upper part of the inner chamber.

3. The smoothing head according to claim 1 , wherein the inner chamber comprises a first diffusion chamber arranged between an inner face of the front wall and a first face of the partition wall extending inside the inner chamber, and a second diffusion chamber partially defined by a second face of the partition wall opposite the first face of the partition wall, the second diffusion chamber being in communication with the first diffusion chamber.

4. The smoothing head according to claim 3 , wherein the first diffusion chamber has a flow cross section gradually diminishing according to the direction of circulation of the steam in the first diffusion chamber.

5. The smoothing head according to claim 1 , wherein a plurality of steam discharge ducts extend transversely to the front wall and communicate with the at least one steam outlet hole such that the steam in the inner chamber escapes through the plurality of steam discharge ducts and towards the at least one steam outlet hole.

6. The smoothing head according to claim 5 , wherein the inner chamber comprises a first diffusion chamber arranged between an inner face of the front wall and a first face of the partition wall extending inside the inner chamber, and a second diffusion chamber partially defined by a second face of the partition wall opposite the first face of the partition wall, the second diffusion chamber being in communication with the first diffusion chamber, and wherein the first diffusion chamber is crossed by the plurality of steam discharge ducts, the plurality of steam discharge ducts projecting from the inner face of the front wall and leading to the second diffusion chamber.

7. The smoothing head according to claim 5 , wherein the treatment face comprises several steam outlet holes, and each steam discharge duct coincides with a respective steam outlet hole.

8. The smoothing head according to claim 5 , wherein the steam discharge ducts have a total cross section area corresponding to a cross section area of the inlet duct.

9. The smoothing head according to claim 5 , wherein each steam discharge duct comprises a barrier rib which projects inside said steam discharge duct and forms a barrier against a flow of water drops along said steam discharge duct towards the at least one steam outlet hole.

10. The smoothing head according to claim 1 , wherein the inner chamber includes a lower wall comprising the condensate evacuation opening.

11. The smoothing head according to claim 10 , wherein the lower wall is curved.

12. The smoothing head according to claim 1 , wherein the condensate return circuit comprises a condensate storage cavity arranged in the smoothing head.

13. The smoothing head according to claim 1 , wherein the condensate return circuit comprises a return duct including a first extremity portion connected fluidically to the condensate evacuation opening, and a second extremity portion opposite the first extremity portion and configured to project into the steam pipe or into the inlet duct.

14. The smoothing head according to claim 1 , further comprising a main body at least partially defining the inner chamber, and a soleplate connected to the main body and including the front wall.

15. A smoothing apparatus comprising a base unit provided with a steam generator and a smoothing head according to claim 1 .

16. A smoothing head comprising a steam distribution circuit and a front wall equipped with a treatment face intended to face a garment to be smoothed, the treatment face comprising at least one steam outlet hole, the steam distribution circuit comprising an inlet duct including an inlet opening intended to be connected to a steam pipe, the steam distribution circuit also comprising an inner chamber, the inlet duct comprising an outlet opening leading to the inner chamber, the inner chamber comprising a condensate evacuation opening communicating with a condensate return circuit, wherein the condensate return circuit is configured to lead to the steam pipe or to the inlet duct,
wherein the smoothing head further comprises a partition wall extending parallel to the front wall configured so as to direct steam emitting from the outlet of the inlet duct along the front wall prior to entering the at least one steam outlet hole, and
wherein the outlet opening leads to the inner chamber tangentially to the front wall, such that the steam exiting the outlet opening flows along the front wall.

17. The smoothing head according to claim 16 , wherein a plurality of steam discharge ducts extend transversely to the front wall and communicate with the at least one steam outlet hole such that the steam in the inner chamber escapes through the plurality of steam discharge ducts and towards the at least one steam outlet hole.

18. The smoothing head according to claim 16 , wherein the inner chamber includes a lower wall comprising the condensate evacuation opening.

19. The smoothing head according to claim 16 , wherein the condensate return circuit comprises a condensate storage cavity arranged in the smoothing head.

20. A smoothing head comprising a steam distribution circuit and a front wall equipped with a treatment face intended to face a garment to be smoothed, the treatment face comprising at least one steam outlet hole, the steam distribution circuit comprising an inlet duct including an inlet opening intended to be connected to a steam pipe, the steam distribution circuit also comprising an inner chamber, the inlet duct comprising an outlet opening leading to the inner chamber, the inner chamber comprising a condensate evacuation opening communicating with a condensate return circuit, wherein the condensate return circuit is configured to lead to the steam pipe or to the inlet duct, and
wherein the smoothing head further comprises a partition wall extending parallel to the front wall configured so as to direct steam emitting from the outlet opening of the inlet duct along the front wall prior to entering the at least one steam outlet hole,
wherein a plurality of steam discharge ducts extend transversely to the front wall and communicate with the at least one steam outlet hole such that the steam in the inner chamber escapes through the plurality of steam discharge ducts and towards the at least one stea
