Fire cover for burner and burner

Abstract

The invention discloses a fire cover for a burner and a burner. The fire cover comprises annular bodies, the annular bodies each include an inner side wall, an outer side wall and a top wall, whereinthe top walls are connected between the tops of the inner side walls and the tops of the outer side walls, and gas grooves with downward openings are formed in the positions between the inner side walls, the outer side walls and the top walls. The fire cover is characterized in that the outer side walls each include a plurality of convex ribs which are distributed at intervals in the circumferential direction and are connected in sequence, the convex ribs are arranged obliquely from top to bottom, fire holes are formed in the convex ribs, and the fire holes are in communication with the gas grooves. The combustion efficiency is high and the combustion load is large.

Description

technical field

[0001] The invention relates to the technical field of burners, in particular to a burner cap and a burner. Background technique

[0002] After the rapid development of gas stoves, the industry has entered a mature stage. With the implementation of energy efficiency grade standards for gas stoves, product thermal efficiency and combustion load have become the focus of enterprises and users. The fire cover is an important part of the gas stove. It directly affects the combustion efficiency and the shape and direction of the flame. The combustion efficiency of the existing fire cover is low, and the gas cannot be fully burned, which leads to the problems of energy waste and low combustion efficiency. Contents of the invention

[0003] The present invention aims to solve one of the problems existing in the prior related art at least to a certain extent. Therefore, an object of the present invention is to provide a fire cover for a burner, which has high combu...

Embodiment 1

[0025] See attached Figure 1-3 It shows a fire cover for a burner proposed by the present invention, which includes an annular main body 1, and the annular main body 1 includes an inner side wall 11, an outer side wall 12 and a top wall 13, wherein the top wall 13 is connected to the inner side wall Between the top of the wall 11 and the top of the outer wall 12, a gas groove 14 with an opening downward is formed between the inner wall 11, the outer wall 12 and the top wall 13, and it is characterized in that: The outer wall 12 includes a plurality of ribs 15 distributed at intervals in the circumferential direction and connected in sequence. The ribs 15 are arranged obliquely from top to bottom, so that the fire cover forms a gear-like shape, and fire holes are arranged on the ribs 15. 16. The fire hole 16 communicates with the gas groove 14. The convex rib 15 is arranged inclined from top to bottom, and the fire hole 16 is arranged on the convex rib 15. The shape of the po...

Embodiment 2

[0030] See attached Figure 4 A burner shown includes the above-mentioned fire cover. The burner is provided with a fire cover, and the outer wall 12 of the fire cover includes a plurality of convex ribs 15 distributed at intervals in the circumferential direction and connected in sequence. A fire hole 16 is provided on the rib 15 , and the fire hole 16 communicates with the gas groove 14 . The burner is provided with an inclined rib 15, and a fire hole 16 is arranged on the rib 15. When the burner is turned on, the burning flame rotates in a certain direction, so that the combustion area is large and the combustion efficiency is high. The convex ribs 15 are equidistantly distributed in the circumferential direction of the fire cover, and the flame distribution is even when burning. Two fire holes 16 are arranged on the convex ribs 15. The number of the flame holes 16 increases, and the combustion load increases, which meets the needs of people.
