Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in FIGS. 1 to 5, the preferred embodiment of the present invention is shown. The burner for the gas stove of the embodiment comprises a fire cover body 1, the fire cover body 1 comprises an annular top wall 11, the annular top wall 11 and an inner annular wall 12 and an outer annular wall 13 which extend downwards from the inner edge and the outer edge of the annular top wall 11 vertically or obliquely, an air mixing cavity 14 is formed jointly, the annular top wall 11 is provided with an inner fire outlet area 15 and an outer fire outlet area 16 which are communicated with the air mixing cavity 14 from inside to outside along the radial direction, the annular top wall 11 is provided with annular inner steps 2 at intervals along the circumferential direction, the inner fire outlet area 15 is located on a first wall surface 21 above the annular inner steps 2, and the outer fire outlet area 16 is located on a second wall surface 22 below the annular inner steps 2. Because the regional division of going out a fire of fire lid is located the regional 15 of going out a fire in being close to the pan center and the regional 16 of going out a fire that keeps away from the pan center relatively in annular inner step 2, and go out a fire regional 15 and go out fire regional 16 and have the difference in height on the axial height of fire lid, can promote secondary air to supply along the regional 15 of going out a fire more fast in the both sides of annular inner step 2 better, it is more abundant to go out the regional 15 burning of a fire in the promotion, in addition, it is located higher level to go out the regional 16 of going out a fire outside than in the regional 15 of going out a fire in interior, then enable the firepower more concentrate on the pan center, finally improve the thermal efficiency of fire lid.

Specifically, in order to make the secondary air around the pot better supplement the inner fire outlet area 15 of the fire lid body 1, the two sides of the annular inner step 2 of the present embodiment also extend towards the outer annular wall 13 of the fire lid body 1 to form a "U" shape. Since the outer annular wall 13 of the fire lid body 1 is adjacent to the periphery of the pot, for this reason, the secondary air can be more quickly supplemented to the inner fire-emitting area 15 along both sides of the annular inner step 2, so as to promote the inner fire-emitting area 15 to be more sufficiently combusted, and thus the thermal efficiency of the whole fire lid body 1 is improved.

In addition, the annular inner step 2 is also provided with a middle fire outlet area 23, and fire holes in the middle fire outlet area 23 are in a long strip shape and respectively extend towards the outer fire outlet area 16 and the inner fire outlet area 15. Because the annular inner step 2 can assist in supplementing secondary air to the inner fire outlet area 15, and in order to enable the area between the inner fire outlet area 15 and the outer fire outlet area 16 to be fully combusted, the annular inner step 2 is provided with the middle fire outlet area 23, and meanwhile, the fire holes are also arranged in a long strip shape, so that the secondary air is supplemented to the outer fire outlet area 16 and the inner fire outlet area 15, and the uniform combustion of the whole fire cover body 1 is facilitated. In addition, the burner of the present embodiment further includes a mounting seat 3, a gas mixing chamber 4 provided on the mounting seat 3 for mixing gas and primary air, the gas mixing chamber 4 including an inner ring wall surface 41 abutting against the inner ring wall 12, an outer ring wall surface 42 abutting against the outer ring wall 13, and a bottom wall 43 connecting the inner ring wall surface 41 and the outer ring wall surface 42; a primary air inlet gap 5 is further arranged in a gap between the mounting seat 3 and the air mixing chamber 4, a first injection pipe 6 and a second injection pipe 7 which are oppositely arranged are further arranged in the primary air inlet gap 5, the first injection pipe 6 comprises a first air inlet 61 and a first air outlet 62 communicated with the air mixing chamber 4, the second injection pipe 7 similarly comprises a second air inlet 71 and a second air outlet 72 communicated with the air mixing chamber 4, and a separation part for separating the first air inlet 61 of the first injection pipe 6 from the second air inlet 71 of the second injection pipe 7 is arranged between the first air inlet 61 of the first injection pipe 6 and the second air inlet 71 of the second injection pipe 7. Because first penetrate the pipe 6 and the second penetrates the reverse setting of pipe 7, can increase first penetrate the pipe 6 and the second penetrates the relative distance between the pipe 7 to avoid two to penetrate the pipe and take place to fight when penetrating primary air, on the other hand penetrates the pipe 6 and the second penetrates to penetrate and sets up partition portion 8 between the pipe 7 at first, can penetrate the pipe to two and penetrate and take place to fight and play more reliable separation effect when penetrating primary air. Finally, the part that the diapire 43 of gas mixing chamber 4 corresponds at first gas outlet 62 of first ejector pipe 6 and second gas outlet 72 of second ejector pipe 7 has depressed part 431, wherein this depressed part 431 can act as the first ejector pipe 6 and the second and draw the expansion section of ejector pipe 7, draw the ejector pipe 7 to extend to gas mixing chamber 4 as far as possible in the direction of flow along the air current in other words first ejector pipe 6 and second ejector pipe 7, under the fixed state of whole combustor size, extend the length that first ejector pipe 6 and second ejector pipe 7 draw in order to improve and draw and penetrate efficiency.
