Abstract

The application discloses a burner, a burner assembly and a stove. The burner includes a lower plate, an upper plate disposed on the lower plate, and a partition plate. The lower plate is formed with a lower duct, and the upper plate is formed with an upper duct. The partition plate is disposed between the lower plate and the upper plate and separates the lower duct from the upper duct. The burner of the embodiment of the application adopts the division plate to divide the lower pore canal and the upper pore canal into two independent sub fire holes, and the cross section area of each sub fire hole is smaller, so that the depth of the sub fire hole is relatively deeper. Therefore, the phenomena of flameout noise and the like caused by flame entering the air passage through the sub fire hole at the moment of closing the gas valve can be avoided. In addition, the equivalent cross-sectional area formed by the lower pore canal and the upper pore canal is not changed, so that the burner can be ensured to have larger flame.

Description

Burner, burner assembly and stove Technical Field The invention relates to the technical field of kitchen appliances, in particular to a burner, a burner assembly and a kitchen range. Background In order to obtain larger flames, the flame holes of the burner are generally arranged relatively large, so that the cross-sectional area of the flame holes is large, and the depth of the flame holes is relatively insufficient, so that flames easily enter the air passage to burn through the flame holes at the moment of closing the gas valve, and flameout noise and the like are generated. Disclosure of Invention Embodiments of the invention provide a burner, a burner assembly and a stove. Embodiments of the present invention provide a burner comprising: A lower plate; An upper plate disposed on the lower plate, the lower plate having a lower duct formed therein, the upper plate having an upper duct formed therein, and And a partition plate disposed between the lower plate and the upper plate and separating the lower duct from the upper duct. The burner of the embodiment of the application adopts the division plate to divide the lower pore canal and the upper pore canal into two independent sub fire holes, and the cross section area of each sub fire hole is smaller, so that the depth of the sub fire hole is relatively deeper. Therefore, the phenomena of flameout noise and the like caused by flame entering the air passage through the sub fire hole at the moment of closing the gas valve can be avoided. In addition, the equivalent cross-sectional area formed by the lower pore canal and the upper pore canal is not changed, so that the burner can be ensured to have larger flame. In some embodiments, the partition plate includes a partition plate body between the lower plate and the upper plate, the partition plate body being substantially circular, and the partition plate further includes a flange bent from an outer peripheral edge of the partition plate body toward the lower plate. Therefore, the flange bends towards the direction of the lower plate to shield the lower duct and the upper duct corresponding to the flange from the air passage, the air outlet quantity of the lower duct and the upper duct corresponding to the flange is reduced, and the flame length of the lower duct and the upper duct corresponding to the flange is further reduced, so that the uniformity of the flame of the lower duct and the upper duct is ensured. In certain embodiments, the rounded angle of the flange is 0 degrees to 180 degrees. Therefore, the flame length of the lower pore canal and the upper pore canal is adjusted by arranging the flanging with a certain arc angle on the partition plate, so that the uniformity of the flames of the lower pore canal and the upper pore canal is ensured. In certain embodiments, the rounded angle of the flange is 0 degrees to 150 degrees. Thus, the flame length of the lower duct and the upper duct can be further accurately adjusted, and the uniformity of the flames of the lower duct and the upper duct can be ensured. In certain embodiments, the lower plate comprises a lower plate body, the upper plate comprises an upper plate body, the lower plate body and the upper plate body are basically in a circular ring shape, the lower pore canals are multiple and distributed along the inner circumference of the lower plate body, the upper pore canals are multiple and distributed along the inner circumference of the upper plate body, the lower plate comprises a lower injection pipe part connected with the lower plate body, the lower injection pipe part is formed with a lower injection pipeline, the lower plate body is formed with a lower air passage communicated with the lower injection pipeline and the lower pore canal, the upper plate comprises an upper injection pipe part connected with the upper plate body, the upper injection pipe part is formed with an upper air passage communicated with the upper injection pipeline, the lower injection pipe part is matched with the upper injection pipe part to form a burner pipe, the lower air passage is matched with the upper injection pipe, the lower air passage is connected with the lower injection pipe, and the pore diameter of the burner pipe is far away from the upper pore canal and the lower injection pipe, and the pore canal is far away from the upper pore canal. Therefore, the lower pore canal and the upper pore canal are mutually matched to generate flame cohesion, and simultaneously, the coating property of the flame on the bottom of the pot is enhanced, so that the combustion efficiency is improved. In addition, the pore sizes of the lower pore canal and the upper pore canal are gradually reduced from the position far away from the outlet of the injection pipe to the position close to the outlet of the injection pipe, so that the flame formed by the fuel gas flowing through the lower pore canal and the upper pore canal far away from the outlet of the injection pipe i
