Small backfire fire cover of backfire oxygen-rich energy gathering gas stove

Abstract

The invention relates to a small fire path fire cover, in particular to a small backfire fire cover of a backfire oxygen-rich energy gathering gas stove, and belongs to the technical field of gas stoves. The small backfire fire cover comprises a small fire path cover body, a plurality of small fire path combustion supporting gas outlet channels are arranged in the small fire path cover body, a plurality of large fire path main combustion gas outlet channels are arranged in the small fire path cover body, and the small fire path combustion supporting gas outlet channels are located in the inner rings of the large fire path main combustion gas outlet channels. Small fire path fire rings are arranged in the small fire path cover body, and the small fire path fire rings are located on the inner rings of the small fire path combustion supporting gas outlet channels. A plurality of small fire path combustion supporting gas outlet holes are formed in the small fire path fire rings, and each small fire path combustion supporting gas outlet hole is correspondingly communicated with the corresponding small fire path combustion supporting gas outlet channel. The small backfire fire cover can be used for supporting combustion of a small fire path main combustion flame of the backfire oxygen-rich energy gathering gas stove, the combustion flame is high in temperature and stable in combustion, the heat efficiency of combustion is high, and little waste gas is generated.

Description

technical field [0001] The invention relates to a small fire channel fire cover, in particular to a backfire small fire cover for an oxygen-enriched energy-gathering gas stove, belonging to the technical field of gas stoves. Background technique [0002] Gas stoves are widely used in society, and every household uses gas stoves. But there are many big and small problems in the gas cooker in the prior art in use. [0003] The existing gas cooker adopts gas injection and air to mix into combustible gas. When the flame temperature during combustion is within an appropriate range, the mixed combustible gas contains high oxygen content, high flame temperature, and high thermal efficiency; low oxygen content, low flame temperature, low thermal efficiency, and more gas consumption. Gas stoves are divided into two levels of fire and fire. The mixer is mostly two mixing tubes. The mixing tube is equipped with a damper. The mixing ratio of air and gas is limited by the damper.

AI Technical Summary

Problems solved by technology

Gas stoves are divided into two levels of fire and fire. The mixer is mostly two mixing tubes. The mixing tube is equipped with a damper. The mixing ratio of air and gas is limited by the damper. Increasing the damper can increase the mixing ratio of air. When the wind speed is increased, the air pressure in the mixer chamber will increase and the flow rate will increase. When burning, the flame will burn from the inside to the outside, and there will be misfires, floating fires, running out of flames, and flameout phenomena, which will affect normal use, cause unsafe factors, and waste energy.

[0004] In the existing gas stove, the combustible gas flow is ejected along the hole around the fire cover circle on the burner, and burns in a straight line from the inside to the outside. Especially, the fire around the fire cover has a certain distance from the center, and the flame does not heat the center of the pot. The high-temperature area of ​​the flame flows to the outer edge of the pot, resulting in low temperature in the center of the pot and high temperature in the outer edge of the pot, and even insufficient combustion and leakage outside the pot. polluted environment

[0005] Existing gas stoves generally only use the upper surface and upper side of the flame, and the heat energy of the lower surface and lower side of the flame is wasted in vain during the combustion process.

Especially when the pot is close to the flame, the upper part of the flame cannot produce a combustion-supporting flame, and it can only be supported by the combustion-supporting flames on both sides, so the flame close to the pot cannot get sufficient combustion support

If the flame is too close to the pot, it will cause black marks on the bottom of the pot and insufficient combustion. If the flame is too far away, the heat energy will be lost due to the distance during the flame combustion process. not tall

Commonly used gas burners generally only have single-channel multi-stage gas outlets for combustion. The flame of single-channel gas outlet combustion is not stable enough, the temperature is not high enough, and the thermal efficiency of combustion is low.
