The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, the present invention provides a burner of a cooking appliance, which includes a fire cover 10 of the cooking appliance and an injection pipe 50 communicated to a gas passage 3 of the fire cover 10 of the cooking appliance. The top surface of the stove fire cover 10 is provided with convex parts 211 and concave parts 212 which are alternately arranged, the convex parts 211 and the concave parts 212 are uniformly distributed along the circumferential direction by taking the central position of the stove fire cover 10 as a rotating shaft, and the convex parts 211 and the concave parts 212 respectively extend to the surface of the side wall 1a of the stove fire cover 10. In addition, the surface of the side wall 1a of the stove fire cover 10 is also provided with outer ring fire holes 11 surrounding the side wall 1a, and the outer ring fire holes 11 are all positioned below the protruding part 211.

The convex parts 211 and the concave parts 212 which are similar to continuous wave crests and wave troughs are arranged on the surface of the stove fire cover 10 to guide overflowing liquid flowing to the surface of the stove fire cover 10, so that the overflowing liquid can flow from the convex parts 211 to the concave parts 212, and the overflowing liquid is guided out along with the flowing of the concave parts 212 to the outer side of the stove fire cover 10, and the overflowing liquid guiding efficiency is improved. Simultaneously, this structure is guaranteeing that outer loop fire hole 11 sets up on lateral wall 1 a's basis, through setting up outer loop fire hole 11 in the below of bulge 211, avoids the overflow can flow into in outer loop fire hole 11 when being guided to lateral wall 1a department of cooking utensils fire lid 10, has solved the easy hydrops of current cooking utensils fire lid 10, perhaps the overflow flows into the defect in fire hole easily.

In the present embodiment, the protruding portions 211 and the recessed portions 212 both extend along the radial direction a of the stove fire cover 10, and are radially distributed with the central position of the stove fire cover 10 as the center. However, this is only a preferred layout, and other layouts such as the protrusions 211 and the depressions 212 arranged in a spiral or rotating radial manner can also achieve the purpose of quickly discharging the overflowing liquid from the top surface of the fire cover 10 of the cooking range.

As shown in fig. 2 and 3, the protrusion 211 of the stove fire cover 10 is transited to the adjacent recess 212 by the inclined plane 213, so that the inclined plane 213 is used to guide the overflow to flow from the protrusion 211 to the recess 212, and the flow speed of the overflow is increased, thereby increasing the efficiency of overflow discharge.
