Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radiant burner in which a radiant is arranged side by side on the side of a burner body and heat is radiated from the radiator.

Conventionally, in this type of burner, a radiant body is provided on the side of the burner body in a frame integral with the burner body, and the burner body and radiant body are integrated in advance so that they can be attached to the appliance, and when both are attached to the appliance separately. It is known that the heat from the radiator is transferred to the burner body through the frame, which can cause defects such as backfire. This has the disadvantage of being prone to combustion.

The purpose of the present invention is to provide a burner that eliminates such inconveniences, and is a type in which a radiator 3 is provided on the side of a burner body 1 in a frame 2 that is integrated with the burner body 1. , a gap 5 is formed between the frame body 2 and the burner body 1 by leaving arm pieces 4, 4 at both longitudinal ends of the burner body 1.

The burner body 1 is constructed by joining a pair of upper and lower metal plates 6 and 6, for example, as shown in FIGS. The frame body 2,
2 are integrally formed, and by bending the arm pieces 4, 4 upward and joining both the metal plates 6, 6, gaps 5, 5 are formed above both sides of the burner body 1, and the frame body 2 is formed. , 2 are installed in parallel.

Although the radiator 3 is made up of a plurality of fins 3a formed by cutting downwards on the frame 2, it can also be made up of a wire mesh 3b attached to the frame 2, for example, as shown in FIG. In this case, a punched piece 2a with a gap 5 is left on the inner side of the frame 2, and a wire mesh 3b is formed between this and the outer side 2b of the frame 2, leaving a gap on the lower side of the frame 2. It was intended to be supported.

FIG. 4 shows still another embodiment, in which a fin 3a is provided in a frame 2 integral with the burner bodies 1, 1 in the middle of a pair of burner bodies 1, 1 arranged side by side with an interval left and right. A radiator body 3 is provided, and a gap 5 is formed between the frame body 2 and each burner body 1 by leaving the arm pieces 4 at both ends in the same manner as described above.

In the illustrated embodiment, a pair of radiators 3 are provided corresponding to each burner body 1, and an exhaust port 10 is opened in the middle thereof.

Next, to explain its operation, according to the combustion operation in the burner body 1, the radiator 3 is heated to red by the combustion flame from the flame port 9,
Radiant heat is radiated from the radiator 3.

In this case, the heat conducted from the radiator 3 to the burner body 1 via the frame 2 is reduced as much as possible because the heat transfer area is narrowed by the gap 5 between the frame 2 and the burner body 1. This prevents the burner body 1 from overheating, and furthermore, secondary air is supplied from above through the gap 5 to achieve good combustion.

In this way, according to the present invention, the frame body 2 on which the radiator 3 is provided
A gap 5 is created between the burner body 1 and the arm pieces 4 at both ends.
The heat transfer from the radiator 3 to the burner body 1 is prevented as much as possible by the gap 5, and secondary air is also supplied through the gap 5, resulting in poor combustion. This method has the effect of reliably resolving the above-mentioned disadvantages of the conventional method.
