Abstract

The enclosed energy-saving environmentally-friendly domestic gas stove not only saves coal gas but also is less in pollution. Three ranks of radial distribution gas holes are uniformly distributed between the interior and external ring gas holes. The radial spacing of the gas hole is small. The inner flame can timely ignite the outer flame with no leakage or gas dissipation. A fuel economizer which can absorb heat energy dissipation of the furnace flame for reutilization is arranged on the pot frame. The axial line of the external ring gas hole trends toward the center of furnace end, which reduces the heat dissipation of the flame column. The horn wind pipe positioned in the lower part of furnace end accelerates introduction air current in throat opening point and increases the air flow. The air vent arranged in the bottom of the furnace mantle and the horn positioned in the lower part of the fuel economizer make furnace end obtain air feed from different directions. The air throttle regulates air feed so that the furnace flame can attain optimal state of combustion. A furnace mantle is covered on the cooker plate. The pot is put on the pot ring in the pot port point so that the furnace mantle can be properly closed. The burned gas and foreign odor collected in the furnace mantle are excluded via the pipeline, which reduces indoor pollution and generates low pressure area beneath the pipe joint, then forms pressure difference with air-duct point, therefore, this generates the exhaust and introducing function for intake air. The cooked food can be placed on the upper and lower parts of the shelf stand in the middle of the cooker plate and the middle part of the upper surface of the furnace mantle for temperature protection. The utility model can make full use of heat energy, the furnace mantle can prevent flameout because of the strong wind, and the lug boss positioned on the upper part of the pot ring can prevent flameout because of the overflo.
