Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gas burner device used in a gas stove or the like.

(Prior Art) Conventionally, a damper cap is provided at the end opening of the mixing pipe of a sheet metal gas burner in which flanges are provided along the length on both sides of the mixing pipe connected to the burner head, and a gas nozzle is connected through the damper cap. A gas burner device is known in which the gas burner is inclined to face the inside of the mixing tube and the opening side thereof is lower than the burner head, and the gas burner device is further provided with a gas burner device in which the boiling liquid flows through the flange and is located below the opening at the end of the mixing tube. In order to eliminate the problem of heat on other parts, there are also known damper caps equipped with wide flange. (Utility Model Application Publication No. 60-6944) (Problem to be solved by the invention) However, this device has a wide flange on the damper cap that is inserted into the opening at the end of the mixing tube, so that the boiling liquid flows into the mixing tube. When the boiling liquid flows from the flange of the mixing tube to the flange of the damper cap, it is unavoidable that the boiling liquid will enter the gap between the mixing pipe and the damper cap, and there is a risk that the damper cap will corrode due to the infiltration of the boiling liquid. Although this can prevent the problem of boiling liquid spilling onto the parts located at the bottom of the opening, it does cause problems such as the amount of man-hours it takes to provide a wide flange on the damper cap.

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

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a gas burner device according to claim 1, which is a gas burner device made of sheet metal in which flanges are provided along the length direction on both sides of a mixing pipe connected to a burner head. A damper cap is provided at the end opening of the mixing pipe of the gas burner, and the gas nozzle faces into the mixing pipe through the damper cap, and is inclined so that the opening side is below the burner head, The gas burner device according to claim 2, wherein at least a part of the flange is inclined obliquely downward toward the outside thereof, the gas burner device according to claim 1
In the gas burner device described above, the width of the flange on the opening side of the end of the mixing tube is made larger than the width of the gas tank connected to the nozzle and other parts facing the lower part of the opening on the end of the mixing tube.

(Function) In the gas burner device having the above configuration,
The broth on the flange flows to the opening side of the mixing tube according to the inclination of the mixing tube, which is not particularly different from the conventional example, but at least a part of the flange is inclined obliquely downward toward the outside. Therefore, the flow of the broth is directed to the outside of the flange at the inclined portion and flows down from the outer edge of the flange. For this reason, there is no flow toward the damper cap provided at the end opening.

In the gas burner according to claim 2, by simply making the width of the flange on the opening side of the end larger than the width of the gas cooker or other parts facing the lower part, the boiling liquid flowing down from the outer edge of the flange can flow to the lower part. You can prevent it from getting on the parts you are exposed to.

(Example) An example of implementing the present invention will be explained with reference to the attached drawings.

In the drawing, reference numeral 1 indicates a gas burner made of sheet metal, in which a mixing tube 3 connected to a burner head 2 is provided with flanges 5 along its length on both sides, and a damper cap 6 is provided at an end opening 4 of the mixing tube 3. The damper cap 6 is attached to the gas appliance main body A so that the gas nozzle 7 faces the inside of the mixing pipe 3 through the central through-hole, and the opening 4 side is below the burner head 2.

In the present invention, the flange 5 is provided so as to be inclined obliquely downward toward the outside of the flange 5. To explain this in more detail, the gas burner 1 has an upper half divided into an upper half and a lower half. 3a and the lower half 3b are formed by caulking or spot welding flanges 5a and 5b that extend not only to both sides of the mixing pipe 3 but also around the burner head 2, and the upper and lower flanges 5
The edge 5c of the flange 5 on the opening side of the end of the mixing tube 3, which is formed by overlapping the flange 5a and 5b, is provided so that the outside thereof protrudes in the length direction of the mixing tube 3 rather than the inside thereof, and has a width w equal to that of the nozzle 7. The width of the part 8 facing the lower part of the end opening 4 of the mixing pipe 3 was made larger than the width of the gas tank and other parts connected to the mixing pipe 3.

By doing this, the broth spilled onto the flange 5 from the opening C of the sauce pan B can be allowed to flow down from the outer edge of the flange 5 before reaching the damper 6, as shown by the arrow in FIG. It is possible to prevent this from flowing and also prevent it from falling onto the pot and other parts 8 without requiring the man-hours required in the conventional method.

In the above-described embodiment, the entire area of the flange 5 is inclined obliquely downward toward the outside, but only the lower end side of the flange 5 may be inclined obliquely downward toward the outside. According to the above, the broth spilled from the opening C of the soup pan B onto the flat part of the flange 5 flows over the flat part of the flange 5 toward the lower end.
Since the lower end side of the flange 5 is an inclined part that is inclined downwardly toward the outside, the flow toward the outside at the inclined part on the lower end side is similar to the case where the entire area of the flange 5 is inclined. Since it falls from the edge, it is possible to prevent the boiling liquid from flowing to the damper cap 6 side.

Further, as shown in FIGS. 5 and 6, only the central portion may be provided with an inclined portion 5d, and according to this, the juice tray B
The broth spilled onto the flange 5 from the opening C flows down from the outer edge of the flange 5 toward the outside of the flange 5 at the inclined portion 5d, and does not flow to the lower end side 5c of the flange.

Incidentally, the broth that has fallen onto the upper half 3a of the mixing tube 3 is
It flows down to the upper side of the inclined part 5d of the flange 5 along the inclination of the circumferential surface of the mixing tube 3.
If a bead 9 is provided in the mixing tube 3 as shown in the figure,
This can also be prevented.

(Effect of the invention) As described above, according to the present invention, at least one part of the flange is provided so as to be inclined obliquely downward toward the outside of the flange, so that the broth on the flange is directed to the end of the mixing pipe according to the inclination of the mixing pipe. When flowing to the opening side, at least one part of the flange slopes outward and does not reach the damper, so that the boiling liquid does not enter the gap between the mixing pipe and the damper cap. Therefore, the problems seen in the conventional example can be solved, and as claimed in claim 2, the width of the flange on the opening side of the end of the mixing tube can be changed to the width of the flange on the opening side of the end of the mixing tube, such as that of the gas tank connected to the gas nozzle and other parts facing the lower part of the opening on the end of the mixing tube. When making the cap wider than the width, it is possible to prevent boiling liquid from getting on the part with less man-hours than the conventional damper cap with a wide flange.
