Abstract

本实用新型公开了一种燃烧器，包括炉头、扣合在炉头上并且与其形成有环形燃气腔的火盖；火盖在其外周部上具有一系列沿周向间隔分布并且贯通盖壁的主火孔，火盖在其外周部且紧邻主火孔的部位具有周向延伸并且由火盖外壁向内凹陷形成的稳焰槽，稳焰槽内具有一系列沿周向间隔分布并且贯通盖壁的稳焰孔，并且，稳焰孔的孔长度小于主火孔的孔长度。本实用新型还公开了具有该燃烧器的燃气灶。本实用新型的有益效果在于，能够提高火焰稳定性及传火可靠性，有效避免缺火以及离焰现象。

Claims

1. A burner, characterized by Includes the burner head and the burner cap (1) which is fastened to the burner head and forms an annular gas chamber therewith. The flame cap (1) has a series of circumferentially spaced main flame holes (a) on its outer periphery (11) that penetrate the cap wall. The flame cap (1) has a circumferentially extending flame stabilizing groove (g) on ​​its outer periphery (11) and adjacent to the main flame holes (a), which is formed by the inward indentation of the outer wall of the flame cap (1). The flame stabilizing groove (g) has a series of circumferentially spaced flame stabilizing holes (b) that penetrate the cap wall. The length of the flame stabilizing holes (b) is less than the length of the main flame holes (a).

2. The burner of claim 1, wherein The flame stabilizer groove (g) is located below the main flame hole (a) and is adapted to make the height of the inner opening of the flame stabilizer hole (b) on the inner wall of the flame cap (1) lower than the height of the inner opening of the main flame hole (a) on the inner wall of the flame cap (1).

3. The burner of claim 1, wherein The opening directions of the flame stabilizing hole (b) and the main fire hole (a) are arranged such that the inner opening of the flame stabilizing hole (b) on the inner wall of the fire cap (1) is located radially outside the inner opening of the main fire hole (a) on the inner wall of the fire cap (1).

4. The burner of claim 1, wherein The diameter of the flame stabilizing hole (b) is not greater than the diameter of the main fire hole (a).

5. The burner of claim 1, wherein The main flame hole (a) and the flame stabilizing hole (b) are arranged staggered in the circumferential direction.

6. Burner according to any of claims 1-5, characterized in that The outer periphery (11) of the flame cap (1) is divided into multiple segments in the circumferential direction. At each end of the outer periphery (11) corresponding to each segment, there are perforated side portions (12) extending in the cross direction and with their inner walls facing the gas flow direction (r) in the annular gas chamber, and solid side portions (13) extending in the cross direction and with their inner walls facing away from the gas flow direction (r) in the annular gas chamber. The perforated side portions (12) have a series of side flame holes (c) that are spaced apart in the cross direction and penetrate the cap wall.

7. The burner of claim 6, wherein The outer peripheral portion (11) and its corresponding perforated side portion (12) have a flame transmission hole (d) at their intersection. The flame transmission hole (d) is arranged to penetrate the cover wall and its outer opening is partly formed on the outer wall of the perforated side portion (12) and partly formed on the groove wall of the flame stabilizing groove (g).

8. The burner of claim 7, wherein The diameter of the flame transfer hole (d) is not less than the diameter of the flame stabilizing hole (b) and the side flame hole (c).

9. The burner of claim 6, wherein At least two of the flame stabilizing holes (b) on the outer peripheral portion (11) corresponding to one end of the solid side portion (13) are arranged such that the spacing between these flame stabilizing holes (b) is smaller than the spacing between the remaining flame stabilizing holes (b), and they form a group of reinforcing holes (e).

10. A gas hob, characterized in that Includes the burner according to any one of claims 1-9.
