Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a gas burner that is used by being assembled into a gas stove.

[Prior Art] Conventionally, this type of burner has a burner main body with a protrusion that protrudes outward from the entire circumference of the upper edge of an outer cylinder in the form of a brim, which is formed by press molding of sheet metal, and a burner cap is mounted on the protrusion. A gas burner is known from Japanese Utility Model Application Publication No. 59-32829, in which the outer peripheral end between the protrusion and the burner cap is connected to the gas distribution chamber, and as shown in FIG. Body a
A gas burner f consisting of a burner body d formed by a casting method and a burner cap e above it is disposed in the center of an opening c formed in a top plate b, and the top plate b existing on the outer periphery of the gas burner f is The gap between
It is also known that the opening c is covered with a juice pan g or a cover ring which is placed on the entire periphery of the opening c.

(Problem to be solved by the invention) However, in the case of the former, when this is assembled into a gas conditioner, a gap is provided between the burner body and the liquid saucer, and secondary air is supplied to the gas burner from this gap. Therefore, there is a risk that the broth may enter the gas stove through the gap, and in the latter case, the flame port h of the gas burner f is blocked by the sauce pan g, etc., making it difficult to supply secondary air. Therefore, there is a problem in that it is difficult to obtain sufficient secondary air necessary for combustion in the gas burner f.

The object of the present invention is to obtain a gas burner free of such defects.

(Means for Solving the Problem) In order to achieve the above object, the present invention has a burner body formed with a protrusion that protrudes outward from the entire circumference of the upper edge of the outer cylinder in the form of a brim, which is press-molded from sheet metal. In a gas burner, a burner cap is provided on the protruding part, and the outer circumferential end between the protruding part and the burner cap is a flame port connected to the gas distribution chamber. A vertical part is provided that bends downward in the direction, and a flange is provided that protrudes outward from the lower part of the vertical part over the entire circumference, and the vertical part is provided with a flange part that directs secondary air from below the protruding part to the flame port. It is provided with an air hole for supplying air.

(Example) Next, the present invention will be described based on an illustrated example.

In FIGS. 1 to 3, reference numeral 1 indicates a gas stove body, and a rectangular opening 3 is provided in the top plate 2 of the body 1, and an outer peripheral edge 4a is provided at the mouth edge 3a of the opening 3.
A juice receiving tray 4 is provided by being supported by.

A part of the gas burner 7 is attached to the gas stove main body 1 through an opening 4b provided in the center of the soup saucer 4 so as to face the upper part of the soup saucer 4.
The gas burner 7 includes a burner body 5 which is press-molded from a metal plate and has a protrusion 5b that protrudes outward from the entire circumference of the upper edge of an outer cylinder 5a, and the burner body 5.
and a burner cap 6 provided on a protrusion 5b, with the outer peripheral end between the protrusion 5b and the burner cap 6 serving as a flame port 10. In the drawing, 5f indicates an inner cylinder provided in the gas stove main body 1, and the outer cylinder 5
A gas chamber 5c was formed on the plate of the inner cylinder 5f and the inner cylinder 5f. In the drawing, reference numeral 11 indicates a trivet integrally provided with a removable cover plate 8 extending from the top plate 2 onto the saucepan 4, 12 a cover ring that covers the gap between the gas burner 5 and the saucepan 4, and 13 a control unit. Indicates a knob.

The configuration up to now is not particularly different from the conventionally known configuration, but in the present invention, a vertical portion 5d is provided that is bent vertically downward from the outer peripheral edge of the protruding portion 5b, and a lower portion of the vertical portion 5d is provided. A flange portion 5e for receiving juice is provided that protrudes outward over the entire circumference from the vertical portion 5.
An air hole 14 for supplying secondary air to the flame port 10 from below the protrusion 5b was provided at d.

In this case, the cover ring 12 was placed on the end of the flange 5e at its inner peripheral edge. However, it is also possible to extend the flange 5e to above the saucepan 4, and in this case, the cover ring 12 becomes unnecessary.

Incidentally, the burner cap 6 is placed on the protruding portion 5b at its comb-teeth portion.

In the illustrated example, the outer diameter ΦA of the burner cap 6 and the outer diameter ΦB of the protrusion 5b of the burner head 9 are
and the inner diameter ΦC of the cover ring 12, ΦC＞
The relationship ΦA>ΦB was established.

(Effects of the invention) Since the present invention is configured as described above, it produces the following effects.

When a gas burner with such a configuration is attached to a gas stove, the flange effectively functions as a soup receiver for receiving the broth produced during boiling. A vertical part is provided that is bent vertically downward from the outer circumferential edge of the vertical part, a flange is provided that projects outward from the bottom of the vertical part over the entire circumference, and a flange is provided on the vertical part from below the protruding part. Since the air hole for supplying air to the burner port is provided, the air hole can be provided near the burner port, and secondary air can be sufficiently distributed from the air hole to the burner port. Moreover, since the air hole is provided in the vertical portion, the boiling liquid will not enter the lower part of the gas burner through the air hole.
