Combustor

Abstract

The invention provides a combustor with a good wide firepower adjusting effect. The combustor comprises a combustor body provided with a first gas channel, a second gas channel, an inner ring gas mixing cavity channel, a middle ring gas mixing cavity channel and an outer ring gas mixing cavity channel, a plurality of nozzles are arranged in the combustor body, an inlet of at least one nozzle is communicated with the first gas channel, and an outlet of at least one nozzle is communicated with the inner ring gas mixing cavity channel; an inlet of at least one nozzle is communicated with the second gas channel, and an outlet of the nozzle is communicated with the middle ring gas mixing cavity channel; and an inlet of at least one nozzle communicates with the second gas channel, and an outlet of the nozzle communicates with the outer ring gas mixing cavity channel. According to the combustor, through the multiple nozzles arranged in the combustor body, inner ring fire, middle ring fire and outer ring fire can correspond to independent gas mixing cavity channels under the condition of the two gas channels and are injected through the independent nozzles, and efficient wide-range control over three-ring fire power through the two gas channels is achieved.

Description

technical field [0001] The invention relates to a gas appliance, in particular to a burner, and belongs to the technical field of gas equipment. Background technique [0002] Gas stoves are commonly used household stove products. There are many Chinese cooking methods. The cooking scenes of frying, frying, deep-frying, steaming, stewing, and stewing require different burner firepower. The firepower adjustment is an important indicator for measuring household stoves. Big fire but not small fire, small fire and small fire are the pain points in the design of existing cooker products. How to use a set of burners to realize the wide combustion firepower adjustment of big fire and small fire at the same time is a difficult problem in the industry. [0003] In the prior art, it is common practice to set up three independent gas passages to provide the gas required by the inner ring fire, the middle ring fire and the outer ring fire respectively, and the firepower control can be ca...

Problems solved by technology

[0003] In the prior art, it is common practice to set up three independent gas passages to provide the gas required by the inner ring fire, the middle ring fire and the outer ring fire respectively, and the firepower control can be carried out by adjusting the gas flow of each gas passage separately, but this scheme Increase product cost, not conducive to marketing

[0004] The Chinese invention patent application with the application number 2019111593624 discloses a gas cooker that realizes wide combustion. The inner ring fire hole is opened on the top of the inner fire cover and the middle ring fire hole is opened on the side wall, and a separate and inner fire hole is formed in the inner fire cover. The inner ring fire gas mixing chamber connected with the ring fire channel reduces the lower limit of the fire power adjustment and solves the problem that the small fire is not small enough and the flame is unstable in the low fire state, but the gas cooker still needs to use three independent gas channels Gas supply, so the product cost is relatively high
