Abstract

PURPOSE:To obtain the burner plate achieving strong heat radiation and steady burning condition by a method wherein plural flame holes are surrounded by a protruded wall. CONSTITUTION:Many flame holes 2 are bored on a burner plate 1 formed by bonding an inorganic particle or a fibrous material. Those plural flame holes 2 are surrounded by a protruded wall 3 in square-shape, thus, a flame holes group 4 are formed. Thereby, the surface temperature can be obtained nearly as same as that of the uneven plate, further, an uniform radiating surface over nearly whole surface can be obtained without any lower temperature part. The steady burning performance can be increased by the protruded wall without affected by a wind, furthermore, the infrared rays radiating burner can be obtained without requiring any glass cover.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a burner plate used in infrared radiation type stoves, grills, and the like.

Conventional Structures and Problems Many burner plates that emit infrared rays have been proposed in the past. Among these, those shown in Figs. 1 and 2 have been proposed for the purpose of increasing the red-hot temperature and stabilizing combustion. Fig. 1 shows the burner plate surface 1 having unevenness formed thereon, and the flame holes 2 placed in the recesses using an i-piece + or taimono.Fig. Hole 2
The burner plate 1 has reeds with holes, both of which are aimed at increasing the radiation area and stabilizing the flame through the unevenness.

However, compared to the conventional flat plates, these have a somewhat higher surface temperature and stronger radiation intensity, and have produced good results such as eliminating the need for glass covering the entire surface of the plate, which was required in the past, but they do have flame holes in the recesses. As a result, it was difficult to form a flame in this area, resulting in the formation of black grooves on the plate surface, resulting in insufficient visual and radiant strength.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a burner plate capable of achieving stable combustion with stronger radiation intensity in response to the above-mentioned problems.

Structure of the Invention The present invention forms a group of independent flame holes on a burner plate by surrounding a plurality of flame holes with projecting walls, thereby achieving mutual flame interference and heat retention and flame holding effects by the surrounding projecting walls. This is to achieve the above objectives.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

1 is a burner plate formed by bonding and molding inorganic particles or fibrous materials such as A7203 or 5i02, and is provided with a large number of flame holes 2. Reference numeral 3 denotes a protruding wall that surrounds a plurality of flame holes 2 in a square shape, and in this example, the protruding wall 3 in which 16 flame holes are arranged in a square shape surrounds and forms one flame hole group 4. . The width of one group of flame holes in the projecting wall 3 needs to be wide enough to allow sufficient flame formation in the flame holes 2, and is preferably 4 to 6 flame holes or more. The flame hole group 4 is arranged in a pattern depending on the purpose and forms one burner plate 1. The height of the protruding wall also varies depending on the purpose, but is preferably about 1 to 8 mm. Further, since the thinner the protrusion wall is, the higher the temperature of the protrusion wall itself is, and the higher the radiation intensity is, the plate may be formed and processed from a honeycomb body.

When used as a burner plate with the above configuration, a flame is formed in each flame hole 2. At this time, since a plurality of flame holes 2 are separated and surrounded by protruding walls 3, self-heating is performed in each flame hole group. Namely, mutual thermal interference in the enclosed inner periphery, heating of the protrusion wall and interference with the protrusion wall, reduction of the inflow of diffused air from the surroundings to the flame base, and reduction of wind turbulence and cooling, etc. One narrow self-heating The plate surface temperature rises due to the effect of forming a space (in experiments, it was 50 to 10
0℃). The surface temperature of these shibrate plates was approximately equal to or higher than that of the conventional uneven flat plate, and in combination with the increased temperature of the protruding walls, a strong radiation surface with no low-temperature areas could be obtained.

Effects of the Invention As described above, by using the burner plate of the present invention, it is possible to obtain a surface temperature comparable to that of an uneven plate, a substantially uniform radiation surface with no low-temperature parts, and a projection wall. To provide an infrared radiation burner which has increased stability against wind and does not require a glass cover.
