Fire covers, burners and gas cooktops containing them

Abstract

The invention discloses a fire cover, a burner containing the same and a gas cooker, wherein the surface of the fire cover has a plurality of first fire hole units and a plurality of second fire hole units, the first fire hole units are connected with all the fire hole units. The second fire hole units are alternately arranged along the circumferential direction of the fire cover; when the second fire hole units are not ignited, the first fire hole units can communicate with each other; when the second fire hole units When the units are ignited, the adjacent first fire hole units can transmit fire to the second fire hole units. Compared with the traditional multi-layered fire hole structure, the fire cover, the burner containing the same and the gas cooker, because the first fire hole unit and the second fire hole unit are distributed at the outer edge of the fire cover, they do not There is a difference between the inner and outer ring fire holes of the traditional burner, and it will not cause the insufficient amount of combustible oxygen in the inner fire hole, which will affect the maximum fire power during use.

Description

technical field [0001] The invention relates to the field of gas cookers, in particular to a fire cover, a burner containing the same, and a gas cooker. Background technique [0002] For civil gas cookers, when the maximum firepower (load) of the burner cannot meet the user's requirements, the most common solution is to use a multi-ring fire design, that is, an outer ring fire, an inner ring fire, or even a middle ring. The method of fire to increase the number of fire holes, and then achieve the purpose of increasing the maximum firepower of the burner. [0003] However, under the condition that the size of the fire cover remains the same, this design scheme of increasing the number of fire holes by adding multiple ring fires to increase the load may lead to insufficient amount of combustible oxygen in the fire holes in the middle or inner ring, resulting in insufficient combustion. sufficient situation. Therefore, this design using multiple ring fires has a very limited ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defect that the burner in the prior art cannot effectively improve the maximum firepower of the burner due to the lack of combustible oxygen in the inner fire hole, and to provide a fire cover, including its combustion chamber. appliances and gas hobs
