Description

[Detailed description of the invention] The invention consists of integrally forming a plurality of concave curved portions 1, which will become a plurality of mixing pipe portions, on a metal plate by press molding, and at the same time, providing ventilation windows 6 between the concave curved portions 1. The burner body 2 is shaped like a burner body 2, and a perforated plate 3 having a ventilation window 61 corresponding to the ventilation window 6 is covered on the side surface of the opening of each concave curved portion 1 of the burner body 2, and a side window 6 is formed.
, 6' and the peripheries of the burner body 2 and the perforated plate 3 are clamped together by an edge 7 having a substantially U-shaped cross section. It is possible to prevent the boundary between the mixing tube sections from becoming too hot relative to the roasted material, and also to ensure that each mixing tube section is completely isolated from each other. Gas burner is provided.

The present invention will be explained in detail below using examples.

The burner body 2 has a bottom shape by pressing a metal plate, and in the embodiment shown in the figure, the burner body 2 has two large and small concave portions 1.
a and lb are integrally formed by drawing, and each concave curved portion 1a
, a gas supply pipe 5 is inserted into the concave bent portion 1a and lb from the side wall of the lb.
, 5 to form the concave bent portions 1a, lb into the mixing tube portion 4a.
, 4b.

The burner body 2 also has a peripheral plate of a window 6 that separates the two concave portions 1a and lb.

As the perforated plate 3, a metal or ceramic mesh plate having windows 6' corresponding to the windows 6 is used.
An edge 7 having a substantially U-shaped cross section is attached to the periphery of the side windows 6, 6' and clamped thereto, and the periphery of the burner body 2 and the periphery of the perforated plate 3 are covered with the same edge 7. The mixture of gas and primary air sent from the gas supply pipe 5 to both the mixing pipe parts 4 a and 4 b is connected to the holes in the perforated plate 3 by pressing and clamping the two large and small mixing pipe parts 4 a and 4 b. The fuel is ejected and burns on the surface of the perforated plate 3.

Here, a non-porous blocking plate 8 is arranged approximately in the middle of the perforated plate 3 located in the large mixing tube section 4a to form a non-combustion section 9, so that the heat emitted from the large mixing tube section 4a is The radiation is evenly distributed without being biased toward the center.

The burner thus obtained is attached to the housing (not shown) of a roaster such as a gas oven or a fish roaster by means of a stay 10 attached to the back side, and the large mixing pipe section 4
A is used as the main combustion source, and the small mixing tube section 4b is used as an auxiliary combustion source. Normally, the large mixing tube section 4a is used alone, but when a large amount of heat is required, both mixing tubes are used. Part 4
A and 4B are used together, and when igniting, first fully open the gas cock (not shown) (for example, by rotating 120 degrees) and supply gas to both 4A and 4B to ignite.
When only one of them is used, the gas cock is rotated in the opposite direction, for example, by 30 degrees, to allow gas to flow to only one and stop the gas supply to the other.

As described above, the present invention uses press molding to integrally form a plurality of concave curved parts whose insides become mixing pipe parts. Therefore, it is possible to easily create a plurality of mixing pipe parts in a plate material. Of course, it has the advantage of being able to accurately set the relative positions of multiple mixing tube sections, and since ventilation windows are provided between the mixing tube sections, there is a This has the advantage that the exhaust gas accompanying combustion is smoothly discharged by the rising airflow passing through the window.
There is an advantage in that it is possible to prevent the boundary portion of the mixing tube portions from becoming high in temperature with respect to the object to be roasted, which would occur if adjacent mixing tube portions are used at the same time.

In addition, since the edges of the ventilation window and the edges of the burner body and perforated plate are pressed and clamped together at the edges, even if the burner body and perforated plate are warped, the gap between the mixing pipe parts can be reliably isolated. The advantage is that each mixing tube section can be completely independent.
