Three-ring combination type full direct-injection fire distributor applied to household gas stove burners

Abstract

The invention relates to a tri-cyclic combined full direct injection type fire distributor applied to a household gas stove combustor.The tri-cyclic combined full direct injection type fire distributor comprises an outer ring fire distributor body, an outer ring direct spraying net arranged at the top of the outer ring fire distributor body, a bi-cyclic and tri-cyclic integrated fire distributor body and a bi-cyclic and tri-cyclic direct spraying net.An outer ring premixing cavity is formed between an inner ring and an outer ring of the outer ring fire distributor body.Outer ring flow distribution blocks are uniformly arranged in the outer ring premixing cavity.A tri-cyclic premixing cavity is formed in the center in the integrated fire distribution device.A bi-cyclic premixing cavity is formed between the tri-cyclic premixing cavity and the integrated fire distributor body.The fire distributor has the advantages that secondary air supply needed by combustion is more uniform and more comprehensive, due to the fact that gas pressure is sufficient, outer flames of fire are strong, fire power is uniform and centralized, and full premixing atmosphere efficient combustion is achieved; the enough and stable firepower can be guided out to combust normally in a thermocouple flame preserving hole, even if the fire is blown out accidentally, the flames of the small tri-cyclic fire can be transferred to the thermocouple flame preserving hole through a tri-cyclic flame guide hole to enable a thermocouple protecting device to work normally.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a three-ring combination type full direct-injection fire distributor applied to a household gas stove burner. Background technique [0002] Burners have a wide range of target groups, including boilers, smelting furnaces, furnaces, heat treatment and other fields, and industries related to heat energy, where combustion systems are essential. Burners are also collectively referred to as devices that allow fuel and air to be sprayed and mixed in a certain way. According to types and application fields, they are divided into industrial burners, burners, civil burners, and special burners. [0003] In the broad concept of a burner, household water heaters, gas stoves, and even lighters can be considered as a type of burner. According to its working principle, a burner can be defined as a chemical reaction that burns substances. A device that converts heat energy by means of...

Problems solved by technology

[0005] What needs to be pointed out in this case is that the existing fire distribution device has some defects. For example, firstly, it cannot make the secondary air supply required for combustion more uniform and comprehensive, and the firepower of the outer flame is not evenly concentrated, so it cannot be the most direct and effective improvement. thermal efficiency; for another example, high-intensity flames cannot be produced; for another example, when the three-ring small fire burns independently, there is not enough stable firepower to burn normally in the thermocouple fire protection hole. Once it is blown out by the wind, the three-ring small fire cannot quickly Exported to the thermocouple flame hole, causing the valve body to close the valve
