DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking gas burner in which a burner head for discharging gas in a ring shape and a burner body for supplying gas emitted from the burner head to the burner head are divided.

[0002]

2. Description of the Related Art A cooking gas burner composed of a burner head and a burner body is divided. When the burner head is separated from the burner body, the burner head falls off during transportation or the like and is lost. In the case where a plurality of burner heads are mounted, the burner head is set incorrectly.

In order to avoid such a problem, FIG.
As shown in the figure, the burner head 21 and the burner body 22 are sandwiched from above and below by an upper plate 23 and a lower plate 24, and the upper plate 23 and the lower plate 24 are fixed with screws 25 or the like. It was fixed.

[0004]

The above technique uses an upper plate 23, a lower plate 24, a screw 25, and the like to fix the burner head 21 and the burner body 22. Therefore, the number of parts is large. In addition, workability is poor because assembly of the upper plate 23 and the lower plate 24, a hole making step for screws, and a screwing step are required. Further, since the upper plate 23 and the screw 25 are visible, the appearance is poor.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a cooking gas burner which has a small number of parts, is excellent in workability, and has a good appearance.

[0006]

[Means of claim 1]

The cooking gas burner includes a burner body into which gas is supplied, and a cylindrical portion penetratingly disposed in a through hole provided in the burner body, and emits the gas supplied to the burner body in a ring shape. A head, and the burner body is provided by joining upper and lower two plates,
The through-hole is swelled downward from above in the lower plate, is provided in a cylindrical shape having a downward cylindrical end, around the cylindrical portion protruding downward and outside of the through-hole, An annular groove in which a spring ring is mounted is provided along the cylinder end, and the spring ring mounted in the groove is engaged with the cylinder end.

[0007]

[0008]

The tubular portion of the burner head is inserted into the through hole of the burner body, and a spring ring is mounted in the annular groove of the tubular portion projecting downward and outside from the tubular end of the through hole.
Then, the spring ring is locked to the cylindrical end of the through hole, and the burner head is fixed to the burner body.

As described above, since the burner head and the burner body are fixed by the spring ring, the number of parts can be reduced as compared with the related art. Further, since the burner head and the burner body are fixed only by attaching the spring ring to the groove of the burner head, workability is superior to that of the related art.
As described above, since the number of parts is small and workability is excellent, manufacturing costs can be reduced. Further, the spring ring for fixing the burner head and the burner body is invisible to a user or the like, and thus has a better appearance than before.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples and modifications. FIG. 1 to FIG. 5 show an embodiment.
2 is a sectional view of a cooking gas burner, FIG. 2 is a perspective view of a gas stove to which the cooking gas burner is assembled, FIG. 3 is a sectional view of a burner head, and FIGS. 4 and 5 are a side view and a top view of a spring ring.

(Schematic description of cooking gas burner 1) Cooking gas burner 1 is incorporated in gas stove 2.
A burner body 3 into which gas and primary air are supplied;
The burner head 4 for annularly discharging the gas supplied to the burner body 3 is assembled after being provided separately.

(Description of Burner Body 3) Burner Body 3
Has upper and lower two upper and lower plates 5 and 6, and presses upward and downward at predetermined opposing positions of the upper and lower plates 5 so as to swell and deform. The periphery of the plate 5 and the periphery of the lower plate 6 are joined, and the primary air and gas intake 3a, the mixing pipe 3b, and the annular passage 3c are formed by the space formed by the bulging portions of the upper plate 5 and the lower plate 6. It is formed.

At an approximate center of the upper plate 5, there is provided an annular receiving portion 9 on which a number of annular slit projections 8 (described later) are mounted below an umbrella portion 7 (described below) of the burner head 4. Inside the annular receiving portion 9, a gas blowing hole 10 for guiding the air-fuel mixture between the annular receiving portion 9 and the umbrella portion 7 is formed.

At a substantially center of the lower plate 6, there is provided a through-hole 12 through which a tubular portion 11 (described later) of the burner head 4 is disposed below. The through hole 12 is a hole concentric with the above-described gas blowout hole 10 provided in a size substantially matching the outer diameter of the cylindrical portion 11 of the burner head 4. It is provided in the shape.

(Description of Burner Head 4) Burner Head 4
Is a substantially ring-shaped one comprising a substantially ring-plate-shaped umbrella portion 7 disposed on the annular receiving portion 9 and a cylindrical portion 11 disposed through the through-hole 12. It is. A large number of slit projections 8 extending in the radial direction are provided on the lower surface of the umbrella portion 7, and the air-fuel mixture blown out from the gas blowing holes 10 is annularly blown out from the slits between the slit projections 8 to the periphery. .

An annular groove 14 in which a spring ring 13 is mounted is provided around a portion of the cylindrical portion 11 which extends to the lower outside of the through hole 12. The spring ring 13 is a ring made of metal (for example, stainless steel) having a circular cross section with one cut. After the burner head 4 is assembled to the burner body 3, a tool is inserted into the groove 14 of the cylindrical portion 11. It is worn by the operator without using it.

(Operation of the Embodiment) Assembling of main parts according to the invention will be described. First, the burner head 4 is connected to the burner body 3
To be mounted on. Then, the lower part of the cylindrical portion 11 of the burner head 4 comes out below the through hole 12 of the burner body 3. Since the cylindrical portion 11 protruding from the through hole 12 has an annular groove 14, the spring ring 13 is attached to the groove 14. As described above, since the outer diameter of the spring ring 13 is outside the inner diameter of the through hole 12, the spring ring 13 is locked in the through hole 12, and the burner head 4 is fixed to the burner body 3.

(Effects of Embodiment) As described above, the burner head 4 and the burner body 3 are
Is fixed, so that the cooking gas burner 1
Requires fewer parts. Further, the burner head 4 and the burner body 3 are easily fixed only by manually attaching the spring ring 13 to the groove 14 of the burner head 4 without using a tool or the like. Excellent workability of assembly. Furthermore, since the spring ring 13 for fixing the burner head 4 and the burner body 3 is not visible from the appearance of the gas stove 2, the appearance of the gas stove 2 incorporating the cooking gas burner 1 is better than in the past.

[Modification] In the above embodiment, a one-port type gas stove 2 has been described as an example, but the present invention may be applied to a gas stove 2 having two or more ports. In the above-described embodiment, an example in which a circular cross-section is used as an example of the spring ring 13 has been described, but a spring having another shape such as a rectangular cross-section may be used.
