Abstract

A combustion device includes at least one burner, a supporting assembly, and an infrared ray generation assembly. The at least one burner includes a flame outlet; the front cover of the supporting assembly includes a flat cover plate which has a plurality of holes; the infrared ray generation mesh which is disposed on the supporting assembly is corresponding to the flame outlet; the flames generated by the flame outlet heat the infrared ray generation mesh and the cover plate. The intensity of heating can be effectively increased by generating open fire and infrared rays and uniformly heating could be realized as well.

First claim

What is claimed is:

1. A combustion device, comprising:
at least one burner having a flame outlet, wherein the at least one burner is for burning gas to generate flames through the flame outlet;
a supporting assembly including a front cover, wherein the front cover has a flat cover plate which includes a plurality of holes passing between an exterior surface and an interior surface thereof; and
an infrared ray generation mesh being disposed on the supporting assembly and corresponding to the flame outlet, the infrared ray generation mesh facing the interior surface of the cover plate, the infrared ray generation mesh being flame heated by the at least one burner to generate infrared rays passing through the holes;
wherein the supporting assembly includes a rear cover which has a rear plate and a surrounding wall connected to a peripheral edge of the rear plate; the front cover includes a surrounding wall which is connected to a peripheral edge of the cover plate and includes a plurality of first extension parts extending substantially perpendicular from the surrounding wall of the front cover, while a plurality of second extension parts extends substantially perpendicular from the surrounding wall of the rear cover, each of the first extension parts corresponds to each of the second extension parts; and a plurality of fixation parts extends substantially perpendicular from a peripheral edge of the infrared ray generation mesh, each of which is disposed between each of the first extension parts and the corresponding second extension part.

2. The combustion device of claim 1 , further comprising an infrared reflective plate located between the rear cover and the infrared ray generation mesh, wherein the infrared reflective plate has a reflective surface facing the infrared ray generation mesh.

3. The combustion device of claim 2 , wherein the reflective surface has a reflective structure; the reflective structure includes a plurality of convex parts and a plurality of embossings, each of the embossings located between two adjacent convex parts.

4. The combustion device of claim 3 , wherein the convex parts form a matrix arrangement.

5. The combustion device of claim 3 , wherein the convex parts form a staggered arrangement.

6. The combustion device of claim 3 , wherein each of the convex parts is conical.

7. The combustion device of claim 3 , wherein each of the convex parts is a strap in shape, and the convex parts form a parallel arrangement.

8. The combustion device of claim 3 , wherein the infrared reflective plate includes a main board and a surrounding wall connected to a peripheral edge of the main board, and a density of the convex parts on the surrounding wall is greater than a density of the convex parts on the main board.

9. The combustion device of claim 3 , wherein the infrared reflective plate includes a main board which has a middle area and a peripheral area outside the middle area; a density of the convex parts on the middle area is smaller than a density of the convex parts on the peripheral area.

10. The combustion device of claim 2 , wherein the infrared reflective plate has at least one gap.

11. The combustion device of claim 2 , wherein the infrared reflective plate has a plurality of holes.

12. The combustion device of claim 1 , wherein the cover plate is rectangular.

13. The combustion device of claim 12 , wherein the front cover includes an upper side wall which is connected to a top edge of the cover plate and has a plurality of holes.

14. The combustion device of claim 13 , wherein the cover plate has an opening located on an opposite side of the top edge; the flame outlet of the at least one burner is disposed below the opening.

15. The combustion device of claim 13 , wherein the supporting assembly includes a rear cover; the infrared ray generation mesh is disposed between the front cover and the rear cover; the rear cover includes an upper side wall which is located above the upper side wall of the front cover and has a plurality of holes.

16. The combustion device of claim 12 , wherein the front cover includes two side walls connected to two side edges of the cover plate, each of the side walls has a plurality of holes.
