Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved structure of a burner device for a stove, and its object is to position a cover ring that covers a gap created around the head of a burner body.

In a burner for a stove, in particular, as shown in FIG.
The cover 5 has a through hole 6.
In the case where the flame of the pilot burner for ignition is supplied to the flame hole 7 above the head part 4 through this through hole, the flame hole 7 is located oppositely below the position of the through hole 6 and engages with the through hole 6. A fixing plate 8 for positioning the cover 5 is fixed to a burner support plate 9 with screws 10. This requires the fixing plate 8 and its attachment.

The present invention was devised to solve the above problems, and will be explained below with reference to FIGS. 2 and 3.

Reference numeral 11 denotes a juice tray that is attached to the top plate of a well-known gas stove or the like, and has a peephole 12 formed approximately in the center thereof. Reference numeral 13 denotes a gas burner body for a stove, which has a cylindrical head part 14 integrally connected with a mixing pipe 15, and a small diameter part 16 formed in stages in the upper part of the head part 14.
In addition, the opening 18 on the upper surface of the head part 14 is provided with flame holes 19, 19 therein.
A burner cap 20 is removably fitted to form... Further, a groove 21 is integrally formed above the connecting portion of the mixing tube 15 of the head portion 14.

22 is a pilot nozzle for ignition mounted above the main gas nozzle 23 mounted opposite to the end of the mixing pipe 15 and facing the upper surface of the mixing pipe 15 near the head section 14; A spark plug 24 and its mounting bracket 25 are attached to the ignition plug 24, and a counter electrode 26 is integrally formed on the mounting bracket.

Reference numeral 27 denotes a cover ring made of sheet metal that is removably fitted to the stepped portion 17 of the head portion 14, and as shown in FIG. 28, and a passage hole 29 located opposite to the groove 21 on the edge of the fitting hole and having a larger diameter and approximately the same width as the groove 21, and a circumferential end of the passage hole 29. The locking claws 30, 30 that fit into the groove 21 are integrally bent at the portion.

Therefore, during ignition operation, the pilot nozzle 22,
When gas is ejected from the main gas nozzle 23 and at the same time a discharge is generated between the spark plug 24 and the counter electrode 26 to ignite the gas ejected from the pilot nozzle 22, the flame is emitted from the passage hole 29 along the upper surface of the mixing tube 15. Reaching the flame hole 19, 19... part, flame hole 1
Ignite the gas ejected from 9, 19...

On the other hand, when installing the cover ring 27, with the burner cap 20 removed, the small diameter cylinder 16 is inserted into the insertion hole 28 and placed on the stepped portion 17, and then rotated to recess the locking claws 30, 30. It engages in the groove 21. If the locking claws 30, 30 are not engaged in the groove 21, the tips of the locking claws 30, 30 will rest on the upper surface of the stepped portion 17, and the cover ring 27 will be tilted, which can be seen visually. It will be easier to confirm if the burner cap 20 is configured so that the burner cap 20 cannot be properly fitted unless the lengths 30 and 30 are fitted.

As described above, the stove burner device according to the present invention has a cover ring and a locking pawl that engages in a groove formed in the head of the burner body at the circumferential end of the passage hole where the flame of the pilot burner faces. Since it is integrally formed, the locking pawl can be integrally formed at the same time as forming the passage hole, which prevents an increase in the number of parts and machining, and can be constructed at low cost. Furthermore, if the cover ring is installed at a position shifted from a predetermined position, the cover ring is tilted due to the action of the locking pawl, and this can be visually observed, thereby preventing ignition failure due to the position shift of the cover ring.
