Abstract

A combustion device includes at least one burner, a supporting assembly, and an infrared ray generation mesh wherein, the at least one burner includes a flame outlet, and the infrared ray generation mesh which is corresponding to the flame outlet is disposed on a rear cover of the supporting assembly. An outer surface of the infrared ray generation mesh is exposed outside. The infrared ray generation mesh is heated by flames out of the flame outlet. Whereby, open fire and thermal energy of the infrared ray can be generated so as to effectively increase heating intensity and realize uniformly heating as well.

First claim

9. The combustion device of claim 2 , wherein the mesh body has a middle part and two side parts, the two side parts are located respectively on opposite sides of the middle part, the corrugations form a plurality of first crests on the first surface, and the corrugations form a plurality of second crests on the second surface; a distance from each of the first crests to corresponding one of the second crests on the middle part is larger than a distance from each of the first crests to corresponding one of the second crests on each of the side parts.

10. The combustion device of claim 2 , further comprising at least one fixation bar, wherein the at least one fixation bar is joined to the corrugations.

11. The combustion device of claim 2 , further comprising at least one fixation bar, wherein the at least one fixation bar penetrates the corrugations.

12. The combustion device of claim 2 , wherein the corrugations have a plurality of first crests on the first surface, and the corrugations have a plurality of second crests on the second surface; a spacing between two adjacent first crests and a spacing between two adjacent second crests are getting larger from the first part toward the second part.

13. The combustion device of claim 2 , wherein the corrugations extend along the same direction.

14. The combustion device of claim 2 , wherein the corrugations have a plurality of first crests on the first surface, the infrared ray generation mesh includes a retaining mesh joined to the second part, an angle is formed between the retaining mesh and a long axis of each of the first crests on the mesh body.

15. The combustion device of claim 14 , wherein the angle is equal to or greater than 90 degrees.

16. The combustion device of claim 2 , wherein the mesh body is a rectangular shape, a peripheral edge of the mesh body has four edges, two of the opposite edges form the first part and the second part.

17. The combustion device of claim 2 , wherein a peripheral edge of the mesh body is a circular shape, the peripheral edge is divided into two halves, the first part and the second part are located respectively on the two halves.

18. The combustion device of claim 1 , wherein the infrared ray generation mesh includes a mesh body which has a first part and a second part on opposite sides, the first part is closer to the flame outlet than the second part, the mesh body has a plurality of holes near the first part.

19. A combustion device, comprising:
