Abstract

System for attaching the flame igniter electrode to a burner for gas hobs, boilers or the like. The system comprises a deformable seal of substantially annular shape mounted in a groove in the electrode which makes it possible to attach the electrode reversibly to a seat attached to the body of the burner. Attachment takes place through the application of an axial force inserting the electrode into the seat.

First claim

I claim:

1. In a gas hob or boiler, a system for attachment of an electrode for igniting a flame comprising:
a burner body from which there laterally extends a support connected to the burner body, the support being provided with a seat for housing an electrode, the seat being provided with a first groove, the electrode being provided with a second groove opposite the first groove for housing an element for attachment of the electrode; and
a deformable attachment element for the electrode of substantially annular shape, the deformable attachment element being housed in the second groove in the electrode without requiring compression of the deformable attachment element such that, when the electrode fitted with the deformable attachment element is inserted into the seat following the application of an axial insertion force, the deformable attachment element deforms within the seat reversibly attaching the electrode in an operating position within the seat of the support of the burner body,
wherein the first groove and the second groove are configured to hold the deformable attachment element in a sealing position.

2. The system according to claim 1 , in which the deformable attachment element is a material capable of supporting a working temperature within the range from 150° C. to 200° C.

3. The system according to claim 2 , in which the deformable attachment element is a silicone material.

4. The system according to claim 1 , in which the support is one piece with the burner body.

5. The system according to claim 1 , wherein the electrode has an abutting edge with a lower face, the lower face engaging a top surface of the support.

6. The system according to claim 1 , in which the electrode has a further seat for resilient attachment of the electrode to an underside of the support by a resilient clip.

7. The system according to claim 1 , wherein the first groove is defined by a portion of an inner perimeter of the seat that has a larger diameter than either of two adjacent portions of the inner perimeter of the seat.

8. In a gas hob or boiler, an electrode for igniting a flame of a burner comprising:
an insulating body;
a conductor enclosed in the insulating body;
a groove to receive an electrode fixing element; and
an abutting edge with a lower face;
wherein the electrode fixing element comprises a resilient attachment element in the groove, the resilient attachment element of substantially annular shape and configured to permit reversible attachment of the electrode to a burner body when in use following application of an axial insertion force, wherein the resilient attachment element is located in the groove after attachment of the electrode to the burner body; and
wherein the lower face of the abutting edge engages a top surface of a support of the burner body when the electrode is attached to the burner body;
whereby no resilient clip is necessary for attachment of the electrode to the burner body.

9. The electrode according to claim 8 , in which the resilient attachment element is a seal of resilient material of circular section.

10. The electrode according to claim 8 , in which the groove is provided in the insulating body.

11. The electrode according to claim 8 , further comprising a seat for attachment of the electrode to a support through a resilient clip.

12. The electrode according to claim 8 , wherein the groove is defined by a portion of an outer perimeter of the electrode that has a smaller diameter than either of two adjacent portions of the outer perimeter of the electrode.

13. In a gas hob or boiler, a system for attachment of an electrode for igniting a flame comprising:
a burner body from which there laterally extends a support connected to the burner body, the support being provided with a seat for housing an electrode, the electrode being provided with a groove for housing an element for attachment of the electrode, wherein the electrode has an abutting edge with a lower face, the lower face engaging a top surface of the support; and
a deformable attachment element for the electrode of substantially annular shape, the deformable attachment element being housed in the groove of the electrode and located entirely between a first end of the electrode and a second, opposite end of the electrode such that, when the electrode fitted with the deformable attachment element is inserted into the seat and following the application of an axial insertion force, the deformable attachment element deforms within the seat reversibly attaching the electrode in an operating position within the seat of the support of the burner body.

14. The system according to claim 13 , wherein the deformable attachment element is a material supporting a working temperature within the range from 150° C. to 200° C.

15. The system according to claim 14 , wherein the deformable attachment element is a silicone material.

16. The system according to claim 13 , wherein the support is one piece with the burner body.

17. The system according to claim 13 , wherein the groove constitutes a first groove and the seat for attachment of the electrode also comprises a second groove opposite the first groove, the first groove and the second groove being configured to hold the deformable attachment element in a sealing position.

18. The system according to claim 13 , wherein the electrode has a further seat for resilient attachment of the electrode to an underside of the support by a resilient clip.

19. The system according to claim 13 , wherein the groove is defined by a portion of an inner perimeter of the seat that has a larger diameter than either of two adjacent portions of the inner perimeter of the seat.
