a base;

the inner ring fire cover is arranged on the base, and a central air mixing chamber is formed between the inner ring fire cover and the base;

the outer ring fire cover is also arranged on the base, is positioned at the periphery of the inner ring fire cover, and forms an outer ring gas mixing chamber with the base;

the method is characterized in that: the outer ring air mixing chamber is adjacent to the wall surface of the central air mixing chamber, a supplement part for supplementing secondary air is arranged along the circumferential direction, a partition is arranged in the outer ring air mixing chamber and can divide the outer ring air mixing chamber into a first space and a second space which are relatively independent, the first space is communicated with a fire outlet of the outer ring air mixing chamber, the second space is communicated with the supplement part, and the supplement part is communicated with an external air supply part.

In order to form the supplementary part, from the viewpoint of simple structural realization, it is preferable that the outer fire cover includes an annular top wall and an outer annular wall vertically extending downward from an outer edge of the annular top wall, the base, the outer annular wall, the partition and the annular top wall together define the first space, an inner edge of the annular top wall extends toward the central air mixing chamber to form an inner guide edge, correspondingly, the base extends upward toward the inner guide edge to form an inner wall, and an annular seam formed between the inner guide edge and the inner wall forms the supplementary part communicated with the second space.

In order to avoid the overflow from blocking the supplement portion, it is preferable that the inner guide edge is formed with a ring-shaped land in a horizontal direction, and the ring-shaped land constitutes a liquid storage region for storing the overflow. The overflowing liquid generated in the cooking process can be remained in the liquid storage area, and finally the aim of preventing the overflowing liquid from blocking the supplement part is fulfilled.

Further, the annular platform continues inwards and inclines downwards to form a shielding part for shielding the supplement part. The shielding part is arranged obliquely downwards, so that on one hand, the secondary air in the second space can be guided, and on the other hand, the extended part of the shielding part can prevent the supplementing part from being blocked by overflowing liquid.

In order to independently supplement secondary air to the inner ring fire cover, the base is further provided with an outer ring gas channel communicated with the first space, a gas supplementing channel communicated with the second space and the gas supply part, and an inner ring gas channel communicated with the central gas mixing chamber.

Compared with the prior art, the utility model has the advantages of: the outer ring mixes the interior separator of air chamber and can form and become the outer ring and mix the air chamber and separate into relatively independent space, and secondary air forms the independent second space to inner ring fire lid replenishment secondary air through the partition effect of this separator, and this second space and outside air feed portion intercommunication can effectively avoid the not enough phenomenon of inner ring secondary air, help improving the combustor thermal efficiency.

Detailed Description

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

As shown in fig. 1 to 4, the present invention is the most preferred embodiment. The burner for the gas stove in the embodiment comprises a base 1 and an inner ring fire cover 2 arranged on the base 1, a central air mixing chamber 21 is formed between the inner ring fire cover 2 and the base 1, an outer ring fire cover 3 positioned at the periphery of the inner ring fire cover 2 is also arranged on the base 1, an outer ring air mixing chamber 31 is formed between the outer ring fire cover 3 and the base 1, a supplementing part 32 for supplementing secondary air is arranged on the wall surface adjacent to the central air mixing chamber 21 along the circumferential direction of the outer ring air mixing chamber 31, a partition 4 is arranged in the outer ring air mixing chamber 31, the partition 4 can divide the outer ring air mixing chamber 31 into two relatively independent first spaces 311 and second spaces 312, wherein the first space 311 is communicated with a fire outlet of the outer ring air mixing chamber 31, the second space 312 is communicated with the supplementing part 32, the supplementing part 32 is communicated with an external air supply part 5, the partition 4 in the outer ring air mixing chamber 31 can form the second space 312 for partitioning the outer ring air mixing chamber 31 into the relatively independent spaces, the secondary air supplementing the inner ring fire cover 2 by the partition effect of the partition 4, and the second space 312 is beneficial to avoiding insufficient heat efficiency of the burner.

Specifically, in order to form the supplement portion 32, the present embodiment is considered from the viewpoint of simple structure implementation, in which the outer ring fire cover 3 includes an annular top wall 33 and an outer annular wall 34 extending vertically downward from an outer edge of the annular top wall 33, the base 1, the outer annular wall 34, the partition 4 and the annular top wall 33 together define a first space 311, an inner edge of the annular top wall 33 extends toward the central air mixing chamber 21 to form an inner guide edge 330, correspondingly, the inner guide edge 330 of the base 1 extends upward to form an inner wall 11, an annular seam formed between the inner guide edge 330 and the inner wall 11 forms the supplement portion 32 communicating with the second space 312, and the inner guide edge 330 forms a ring-shaped platform 3301 in a horizontal direction, and the ring-shaped platform 3301 forms a liquid storage region for storing a liquid overflow, so that the overflow generated during cooking can be stored in the liquid storage region, and finally, the purpose of preventing the overflow from blocking the supplement portion 32 is achieved.
