Embodiment 1
[0054] Natural gas and air enter the air inlet 1-1 of the base of the burner chassis through the air flow injection pipe 3, enter the air flow diffusion chamber 1-4 through the air flow distribution channel 2-1, and the mixed gas entering the air flow diffusion chamber 1-4 passes along its The slope or arc surface of the edge climbs up and diffuses gradually, which ensures the uniformity and stability of the mixed gas diffusion, so that the mixed gas in the gas flow diffusion chamber 1-4 quickly reaches the static pressure equalization before flowing to the combustion hole, and then the gas flow The mixed gas in the diffusion chamber 1-4 enters the annular airflow chamber of the outer combustion disk 4 to form a clear inner flame cone at the combustion flame, and the secondary air intake groove 1-2 on the base provides a certain speed and sufficient air , enter the outer ring of the inner combustion disk 5 through the three secondary air passages 1-3 of the base, form a diffuse...

The invention relates to a burner chassis. The burner chassis comprises a base and an airflow diffusion plate. An air inlet is formed in the bottom of the base. An air-out channel is formed in the top of the base. Three secondary air inlet grooves are formed in the peripheral edge of the base at the interval of the included angle of 120 degrees with the air inlet as the center. The airflow diffusion plate is arranged on the base. Three airflow distribution channels matched with the base are formed in the airflow diffusion plate at the interval of the included angle of 120 degrees with the air inlet as the center. Three airflow diffusion chambers are arranged on the base at the interval of the included angle of 120 degrees with the air inlet as the center. The edges of the airflow diffusion chambers are bevel in the upward direction. The airflow distribution channels are connected with the centers of the airflow diffusion chambers. According to the burner chassis, the airflow diffusion chamber structure of a traditional burner is changed by reforming airflow distribution chambers, so that static pressure equalization of mixed airflow in the airflow diffusion chambers is rapidly achieved before the mixed airflow flows to a burning hole, and thus flame is ensured to be uniform; the power is improved without adding the diameter of the airflow distribution chambers and the diameter of a head portion, the real sense of high power is achieved, and emission is reduced; the height of an integral cooker is reduced through the structure, and the air inflow and the airflow velocity of secondary air are ensured so that the purposes of stable burning and uniform flame can be achieved.
Description
technical field [0001] The present invention relates to an improved, preferably domestic, gas burner chassis and gas burner, typically used in cooking gas appliances. Background technique [0002] Kitchen gas burners are designed for a single main injector in order to concentrate the heat in the center of the burner, corresponding to the bottom of the cooker, such burners are known and widely used from the literature of the prior art, but these structures A common problem with modern gas burners is that the airflow is unstable and the combustion rate of the gas is not sufficient, which will cause certain environmental pollution and energy waste. Although the CN102348932 patent adopts a completely new design, it includes a distributor device with at least two discrete chambers in the distributor device, each chamber communicates with the flame port and includes a venturi tube to feed it air-gas mixture; said burner has only one manifold to direct gas from a single gas source...
