Fire cover, burner comprising fire cover and gas stove

Abstract

The invention discloses a fire cover, a burner comprising the fire cover and a gas stove, wherein a plurality of first fire hole units and a plurality of second fire hole units are arranged on the surface of the fire cover, and the first fire hole units and the second fire hole units are alternately arranged in the circumferential direction of the fire cover; when the second fire hole units are not ignited, the first fire hole units can conduct fire mutually; and when the second fire hole units are ignited, the adjacent first fire hole units can transfer fire to the second fire hole units. Compared with a traditional structure with multiple layers of fire holes, the fire cover, the burner comprising the fire cover and the gas cooker have the advantages that the first fire hole units and the second fire hole units are distributed at the outer edge of the fire cover at intervals, so that the difference of the fire holes in inner and outer rings of a traditional burner does not exist, the situation that the amount of combustible oxygen in the fire holes in the inner side is insufficient is avoided, and the situation that the maximum firepower is influenced during use is avoided.

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
