Burner fire cover and gas cooker using the fire cover

Abstract

The invention relates to a burner fire cover and a burner cooker using the fire cover, wherein the fire cover includes a ring-shaped fire cover body, the bottom of the fire cover body has an air mixing chamber, and the top of the fire cover body is provided with a The fire transmission groove penetrates along its radial direction, and the fire transmission groove is in fluid communication with the gas mixing chamber. The groove is divided into two regions, the length direction of the fire transfer groove is along the radial direction of the fire cover body, the partition is provided with through holes, and the two regions in the fire transfer groove pass through the The through holes are in fluid communication. The present invention divides the fire transfer tank into two areas by setting a partition, and the two areas are connected through a through hole, so that the two areas are integrated and independent of each other, and can stabilize the flame with each other, so that the transmission The fire is stable and reliable.

Description

Technical field [0001] The present invention belongs to the field of gas cookers, and more particularly to a combustor fire cover and a gas cooker to which the fire is applied. Background technique [0002] At present, the turning fire structure of the burner on the market is mainly from the flame of the inner ring. The fire hole of the outer ring is transmitted through the wireway to ignite the outer ring fire; during transmission, due to the independent structure of the inner and outer ring, it is necessary to set up The fire is turned on. [0003] The outer ring fire cover of the existing gas burner generally uses an open firing structure, such as the Chinese invention patent "a gas cooker burner fire cover", a patent number, which is 201610930412.4 (public numeral CN106642118A). For the 200920202204.8 (authorized bulletin No. CN201555225U) China Utility New Type Patent, the patent number 201420411586.6 (authorized bulletin is CN204006006U), China's utility model patent "," a ...

AI Technical Summary

Problems solved by technology

[0004] The open fire transmission tank has the following defects: First, the open fire transmission tank is easy to cause blockage of the fire transmission tank, that is, the soup flowing down from the bottom of the pot is easy to flow into the fire transmission tank, and the blockage will affect the fire transmission performance. The main reason for the blockage and maintenance of the fire transmission channel; second, the open fire transmission channel has high requirements on the damper of the cooker, because after the damper is opened, too much air at one time will cause the air velocity to be too high, which will cause the flame to leave the flame or fall out during combustion. Therefore, the structural feature of the open fire transfer trough is poor flame stability. Therefore, to ensure the fire transfer performance of the open fire transfer trough, it is basically to close the damper very small, but the small damper is not conducive to the operation of the stove. The combustion efficiency is also not conducive to the emission of smoke, which greatly affects the performance of the stove

[0006] The fire transmission structure prevents the fire groove from being blocked by the fire transmission cover, but the setting of the fire transmission cover will also have an adverse effect on the entry of secondary air, and there is no flame stabilization structure in the fire transmission channel, and the flame stabilization effect is not good
