Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a burner made of sheet metal used as a burner for a bathtub or the like.

(Prior Art) Conventionally, flame ports are formed in rows between a partition plate and an outer plate which is polymerized and bonded at intervals on both sides of the partition plate, and the partition plate is connected to the upper edge of the partition plate. The flame openings are located at almost the same height as the upper edge of the outer plate, and between each burner opening, it is formed lower than the upper edge of the outer plate, so that it is placed above the partition plate between the flame openings. It is known that there are gaps formed on the edges.

(Problem to be solved by the invention) According to this, fire transfer occurs even if there is a gap between the burner ports due to the flame transfer interval. When the plates are spot welded, the gap between one flame port and the other flame hole sandwiching the plates becomes wider, and the distance between the flame holes becomes longer. It becomes difficult for the flame to spread to the other flame.

The object of the present invention is to obtain a sheet metal burner free from such defects.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a row of flame ports between a partition plate and an outer plate which is polymerized and bonded at intervals on both sides of the partition plate. In this case, the upper edge of the partition plate is at approximately the same height as the upper edge of the outer plate at the burner port position, and the partition plate has a part between the plurality of burner ports. In this case, a flame guiding plate is formed by extending over a part of the flame openings located on both sides of the partition plate and protruding upward from the upper edge of the outer plate to form a leg piece, and on top of the leg piece, the leg piece is bent laterally. A transparent window is provided in the leg piece and the partition plate connected below the leg piece, and the upper edge is higher than the upper edge of the outer plate and the lower edge is lower than the upper edge of the outer plate. It consists of

(Function) In this case, one flame port and the other flame port communicate with each other through the transparent window, and the flame from one flame port that was ignited first is suppressed by the guide plate. Head towards the other side of the flame. As a result, the flame also ignites the gas in the transparent window portion that hits both flame ports, thereby ensuring that the flame transfers from the previously ignited flame port to the unlit flame port.

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

In the drawings, reference numeral 1 denotes the space formed between the partition plate 2 and the outer plates 3, 3, which are polymerized and bonded with intermittently spaces on both sides of the partition plate 2. The burner is shown with a burner port 5a, and the upper edge of the partition plate 2 is located at almost the same height as the upper edge of the outer plate 3 at the burner port 5a position, and the burner ports 5b between each burner port and on both sides thereof. 5a is formed lower than the upper edge of the outer plate 3 to form a flame transfer interval on the upper edge of the partition plate 2 between the burner ports 5b, and the partition plate 2 and the outer plate 3 are spaced appropriately. It is fixed by spot welding between the flame openings 5b at the positions.

Then, in order to carry out the spot welding, the partition plate 2 located between the flame ports 5b of the wide part, which is wider than other parts, is placed over the outer plate 3 by straddling part of the flame ports 2 located on both sides thereof. A leg piece is formed by protruding upward from the edge, and a flame guide plate 6 is provided on the upper part of the leg piece by bending it laterally.Furthermore, the leg piece and the partition plate 6 connected below the leg piece are provided with a flame guiding plate 6 on both sides. A transparent window 7 is formed which faces the flame outlet 2 located and has an upper edge higher than the upper edge of the outer plate 3 and a lower edge lower than the upper edge of the outer plate.

In this case, the burner ports 5a, 5a located on both sides of the gap between the burner ports 5b of the wide part are connected to each other via the transparent window 7, and the guide plate 6 exists above them.

In the illustrated example, a pilot burner of a bath burner is shown as a burner, and the pilot burner has a flame guiding plate 6 provided on the side of the air supply port 8 at one end connected to the mixing pipe 4 of the burner 1. The ignition plug 9 was installed in close proximity, and a counter electrode 10 for the ignition plug 9 was formed on a part of the flame guide plate 6.

Incidentally, the center of the flame port 5a is recessed inward, and the partition plate 2 is held between the recessed portion 11.

In the above-mentioned embodiment, the guide plate is particularly provided at the spot weld where the gap between the flame ports widens, but the guide plate is not limited to this.

(Effect of the invention) According to the present invention, the ignited flame of one flame port can be guided to the other unlit flame port side by the guide plate, and the flame can be used to guide the flame from the transparent window provided in the partition plate. The flame guide plate can ignite the gas in the part and form a flame between the flame ports, thereby ensuring that the flame transfers from one side of the flame ports located on both sides between the flame ports to the other. In a part between a plurality of flame ports, a leg piece is formed by extending over a part of the flame ports located on both sides of the partition plate and protruding upward from the upper edge of the outer plate, and the upper part is placed on the side. Since it can be formed by simply bending it in one direction, it has the effect of requiring fewer parts and being inexpensive.
