BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a gas burner according to an embodiment of the invention. Reference numeral 1 denotes a caster burner main body having an opening 4 provided on the upper surface of an annular distribution chamber 3 connected to the mixing pipe 2, and reference numeral 5 denotes a caster burner cap provided with a large number of tooth pieces 6 on the outer peripheral lower surface. The burner cap 5 is placed on the upper surface of the peripheral wall 7 of the opening 4 of the burner body 1 with the lower surface of the tooth piece 6 closed to close the upper surface of the distribution chamber 3. A continuous flame port 8 is formed.

Reference numeral 9 denotes a depression 1 on the side surface of the outer peripheral wall of the burner body
The ignition electrode 9 is attached to the burner main body 1 on the appliance main body side by fixing means (not shown), for example, a screw. Reference numeral 11 denotes a target provided on the lower surface of the ceiling surface of the burner cap 5, and the target 11 was constituted by a projecting piece projecting from the burner cap 5. Reference numeral 12 denotes an engaging portion provided on the burner cap 5 and engaged with the insulator portion 9a of the ignition electrode 9. The engaging portion 12 in the embodiment shown in FIGS.
Forms a space 13 in which two of the teeth 6a, 6a are shifted rearward and the ignition electrode 9 faces the front thereof,
Teeth 6b, 6b located on both sides of the two teeth 6a, 6a
Are formed as long teeth extending from the innermost part of the teeth 6a, 6a to the forefront of the tooth pieces 6, 6 on both sides of the teeth 6b, 6b. An engaging portion 12 for engaging with the insulator portion 9a is provided. This will be further described. A hanging piece is formed at the front of the long teeth 6b, 6b toward the space 13 to form an engaging portion 12.

FIG. 6 shows another embodiment, in which a part of the tooth piece 6 is formed as a horseshoe-shaped tooth 6c having an open front surface, and the space 13 is formed in the horseshoe-shaped tooth 6c. The projection formed on the surface is used as a target 11 and the horseshoe-shaped tooth 6
A hanging piece was formed on both sides of c toward the space 13 side, and this was used as the engaging portion 12. In this embodiment, when the burner cap 5 is placed on the burner main body 1, the burner cap 5 is placed on the lower surface of the tooth piece 6 on the upper surface of the peripheral wall 7 of the opening 4 of the burner main body 1 as shown by a chain line. And the horseshoe-shaped teeth 6c are also placed on the peripheral wall 7 of the distribution chamber 3 of the burner body 1. Reference numeral 14 denotes a gas outlet formed by cutting out the lower side of the horseshoe-shaped tooth 6c.

Other structures are not particularly different from those shown in FIGS.

FIG. 7 shows still another modification, in which a horseshoe-shaped protruding piece which is brought toward the space 13 along the lower side of the horseshoe-shaped tooth 6c of the above embodiment is used as the engaging portion 12. Other configurations are not particularly different from those in FIG.

FIGS. 8 and 9 show still another embodiment. To explain this, a sheath 15 is provided on the burner cap 5,
The inner peripheral surface of the sheath 15 is an engaging portion 12 with which the insulator 9a of the ignition electrode 9 engages. In addition, the gas ejection hole 1 is formed in the sheath 15.
4 was bored to guide gas into the sheath 15. Then, three projections 15a are provided on the inner peripheral surface of the sheath body 15, and the insulator 9a of the ignition electrode 9 is supported by the inner end of the projection 15a. When the burner cap 5 is made of a cast material as in the above-described embodiment, a projection integrally projecting from the burner cap 5 serves as the target 11, but when the burner cap 5 is made of ceramic, a separate metal piece is used. It is formed by attaching to the cap 5 or the like.

In the above embodiment, a large number of teeth 6 are provided on the lower surface of the outer peripheral portion of the burner cap 5, and the burner cap 5
The peripheral wall 7 of the distribution chamber 3 of the burner body 1 is
A so-called open fire burner in which a flame port 8 is formed between the teeth 6 when placed on the upper surface of the burner cap is provided with a large number of teeth on the lower surface of the inner peripheral portion of the burner cap. It is needless to say that the present invention can be applied to a so-called internal fire burner in which a flame hole is formed between each tooth when the lower surface is placed on the upper surface of the peripheral wall of the distribution chamber of the burner main body. Further, in the above-described embodiment, the burner port 8 is formed between the plurality of teeth 6 provided on the burner main body 1 and the burner cap 5, but the burner main body 1 and the burner cap 5 are formed.
The slit formed between and can also be used as a flame outlet,
Further, a hole-shaped flame port formed in the burner cap 5 can be used.

In the above-described embodiment, the ignition electrode 9 is supported by the burner main body 1. However, although the ignition electrode 9 is not shown, the ignition electrode 9 may be supported by an appliance main body such as a stove on which the burner main body 1 is supported. good. Further, in the above-described embodiment, when the ignition electrode 9 and the target 11 are provided so as to be positioned below the ceiling of the burner cap 5, particularly when the burner is used for cooking, the boiled-steamed juice is removed from the ignition electrode 9 and the target. Advantageously, it is possible to avoid direct contact with the target 11, and to prevent poor ignition caused by boiled juice adhering to the ignition electrode 9 and the target 11.

[0014]

As described above, according to the present invention, when the burner cap is attached to the burner main body, the ignition electrode is engaged with the engagement portion of the burner cap, so that the ignition electrode and the target are properly positioned. Thus, a spark can be reliably blown between the ignition electrode and the target, and a gas burner capable of performing good ignition can be obtained. In addition, since the positional relationship between the ignition electrode and the target can be maintained by using the ignition electrode, the number of parts is small, the structure is simple, and the cost is low.
