Dragon wind energy-saving stove

Abstract

The invention discloses a dragon wind energy-saving stove which comprises a base. A hearth frame, a shell and a cover plate are arranged on the base, and an inner hearth and an outer hearth are formed. The cover plate is provided with a stove opening which allows a pot to be put into the inner hearth and is matched with the pot bottom. The hearth frame is provided with spiral fire extending wallswhich are spirally ascended along the inner wall of the hearth frame. A diffraction fire extending wall which divides a spiral channel between the two spiral fire extending walls into a plurality of spirally-ascending fire extending channels is arranged between the two adjacent spiral fire extending walls. The spiral fire extending walls and the diffraction fire extending walls form a spiral pot frame which is used for supporting the pot and matched with the pot bottom. A fire plate opening is formed in the bottom of the hearth frame. A fire plate is arranged at the fire plate opening. An annular fire retaining wall is arranged on the outer side of the spiral pot frame. An annular discharge flue is arranged on the upper portion of the outer hearth. An exhaust port is formed in the cover plate and communicates with the discharge flue. An outer passing port and an inner passing port are formed between the hearth frame and the cover plate as well as between the fire retaining wall and thepot bottom respectively, wherein the portions, close to the exhaust port, of the outer passing port and the inner passing port are small, and the portions, away from the exhaust port, of the outer passing port and the inner passing port are big. The dragon wind energy-saving stove has the functions of fire extending and fire evening, and the thermal efficiency is high.

Description

【Technical field】 [0001] The invention relates to a Longfeng energy-saving cooker. 【Background technique】 [0002] With the development of the economy, more and more energy is consumed, the price is higher and higher, the environment is deteriorating day by day, and the global average temperature is gradually rising. The government vigorously advocates the adoption of new technologies for energy conservation and emission reduction, and strives to ensure an ideal environment for long-term and sustainable development. Three meals a day are indispensable. Although induction cookers, microwave ovens, and rice cookers can boil water to cook rice, high-temperature cooking and stir-frying on open fire are still the mainstream trends. According to the announcement of the authoritative structure, the thermal efficiency of gas stoves on the market is only 40% to 55%. Therefore, the research and development of high-efficiency and energy-saving stoves has broad prospects. [0003] The...

[0014] 6. Atmospheric combustion defects of gas stoves

The ideal combustion state is that more gas requires more combustion-supporting air, and less gas requires less combustion-supporting air. The amount of combustion-supporting air entering the mixing tube is determined by the damper. That is, the best combustion state) is determined, that is, the damper is no longer adjusted during the actual operation of the large fire and the small fire, so that the relative excess of combustion air in the small fire is formed, and the heat energy is taken away; while the combustion air in the large fire is relatively insufficient, the flame turns red, and the gas burns Insufficient, waste of gas
