Abstract

A burner for a gas-heated cooking appliance includes a pipe for mixing burnable gas with primary air, and a deflecting element which is arranged in an interior space which is bounded by the pipe. The pipe has one end which points toward a nozzle of the burner and another end which points toward a cover of the burner. The deflecting element is arranged in the interior space between a center of the pipe in respect of a longitudinal direction thereof and the one end of the pipe.

First claim

The invention claimed is:

1. A burner for a gas-heated cooking appliance, comprising:
a base comprising a lower part and an upper part;
a cover configured to be placed on the upper part;
the lower part comprising a chamber, the chamber having a floor;
a nozzle arranged perpendicularly through the floor and configured to supply gas from a gas supply line;
the upper part further comprising a plate that is generally parallel to the cover and forms a space between the cover and said plate, the plate having flame outlets around the plate's circumference, the plate further comprising an integral pipe that projects downward towards, and coaxial with, the nozzle;
a radial gap for primary air entry formed within the lower part such that primary air may enter under the plate;
the pipe forming a flow path for mixing gas with the primary air; and
a deflecting element comprising at least one piece of wire, the deflecting element suspended within the pipe perpendicular to the flow path formed by the pipe so as to provide further mixing of gas and primary air so it can be supplied to the flame outlets via the space between the cover and plate.

2. The burner of claim 1 , further comprising said pipe having one end which points toward the nozzle and another end which points toward the cover, said deflecting element being arranged between a center of the pipe in respect of a longitudinal direction thereof and the one end of the pipe.

3. The burner of claim 2 , wherein the nozzle is arranged at a distance from the one end of the pipe.

4. The burner of claim 1 , wherein the deflecting element is designed to be cruciform.

5. The burner of claim 1 , wherein the piece of wire has a diameter of between 0 and 3 mm.

6. The burner of claim 1 , wherein the piece of wire has a diameter of between 1 and 2 mm.

7. The burner of claim 1 , wherein the piece of wire has a diameter of between 1.3 and 1.7 mm.

8. The burner of claim 1 , wherein the piece of wire is made of metal or plastic.

9. The burner of claim 1 , wherein the pipe has an inner wall, to which ends of the at least one piece of wire are connected.

10. The burner of claim 9 , wherein the inner wall has a diameter of between 5 and 20 mm.

11. The burner of claim 9 , wherein the inner wall has a diameter of between 8 and 14 mm.

12. The burner of claim 9 , wherein the inner wall has a diameter of between 10 and 12 mm.

13. The burner of claim 1 , wherein the deflecting element has two pieces of wire, which are connected to one another centrally.

14. The burner of claim 1 , wherein the lower part has a chamber open on one side, said pipe being sized to extend into the chamber.

15. A gas-heated cooking appliance having a burner, said burner comprising:
a base comprising a lower part and an upper part;
a cover configured to be placed on the upper part;
the lowest part comprising a chamber, the chamber having a floor;
a nozzle arranged perpendicularly through the floor and configured to supply gas from a gas supply line;
the upper part further comprising a plate that is generally parallel to the cover and forms a space between the cover and said plate, the plate having flame outlets around the plate's circumference, the plate further comprising an integral pipe that projects downward towards, and coaxial with, the nozzle;
a radial gap for primary air entry formed within the lower part such that primary air may enter under the plate;
the pipe forming a flow path for mixing gas with the primary air;
and a deflecting element comprising at least one piece of wire, the deflecting element suspended within the pipe perpendicular to the flow path formed by the pipe so as to provide further mixing of gas and primary air so it can be supplied to the flame outlets via the space between the cover and plate.

16. The gas-heated cooking appliance of claim 15 constructed in the form of a gas hob.

17. The gas-heated cooking appliance of claim 15 , further comprising said pipe having one end which points toward the nozzle and another end which points toward the cover, said deflecting element being arranged between a center of the pipe in respect of a longitudinal direction thereof and the one end of the pipe.

18. The gas-heated cooking appliance of claim 15 , wherein the deflecting element is designed to be cruciform.

19. The gas-heated cooking appliance of claim 15 , wherein the piece of wire has a diameter of between 0 and 3 mm.

20. The gas-heated cooking appliance of claim 15 , wherein the piece of wire has a diameter of between 1 and 2 mm.

21. The gas-heated cooking appliance of claim 15 , wherein the piece of wire has a diameter of between 1.3 and 1.7 mm.

22. The gas-heated cooking appliance of claim 15 , wherein the piece of wire is made of metal or plastic.

23. The gas-heated cooking appliance of claim 15 , wherein the pipe has an inner wall, to which ends of the at least one piece of wire are connected.

24. The gas-heated cooking appliance of claim 23 , wherein the inner wall has a diameter of between 5 and 20 mm.

25. The gas-heated cooking appliance of claim 23 , wherein the inner wall has a diameter of between 8 and 14 mm.

26. The gas-heated cooking appliance of claim 23 , wherein the inner wall has a diameter of between 10 and 12 mm.

27. The gas-heated cooking appliance of claim 15 , wherein the deflecting element has two pieces of wire, which are connected to one another centrally.
