The utility model provides a kind of flameless infrared radiation combustion stove, and the combustion stove includes furnace body, grate tray and heat accumulator, furnace body is equipped with annular furnace cavity, built-in spiral flow guide passage, bottom is equipped with tangential air inlet, so that combustible gas rotates flow along spiral trajectory, realizes pressure balance by centrifugal force;Grate tray is located in the upper portion of furnace cavity, is equipped with grate hole, inserts straight cylinder shape gas outlet pipe, gas outlet pipe is placed combustion nozzle;Heat accumulator is placed above grate tray, is equipped with heat storage hole corresponding with grate hole, gas outlet pipe and combustion nozzle are inserted therein, and heat accumulator absorbs combustion heat energy and converts into infrared and radiates.The stove realizes pressure balance by the rotating flow of combustible gas in spiral flow guide passage, forms flameless combustion on the upper portion of combustion nozzle after entering gas outlet pipe through grate hole.The heat accumulator converts combustion heat energy into infrared radiation, and simultaneously combines heat conduction and heat convection, efficiently transfers heat energy to the object to be heated.

The present invention provides a stove with a fume exhaust function. The combustion area of ​​the gas stove is located below the heat-conducting panel, and the pot is directly placed on the heat-conducting panel. The infrared heat energy generated by the combustion of the burner transfers the heat energy to the pot through the heat-conducting panel to heat it. The upper surface of the stove becomes neater and easier to clean, and the wind resistance of small and micro fires is stronger. The defect of the pot placed on the elevated pot rack in the prior art is overcome, and the combustion is more stable. Moreover, on the one hand, the exhaust system on the stove body absorbs and exhausts the fume generated during the cooking process of food. On the other hand, the same fan can also produce a pneumatic effect when it is running, which promotes the hot fume generated by the combustion in the combustion chamber to be sucked into the exhaust system and then discharged together with the airflow containing fume sucked from the fume suction port. It can not only absorb and exhaust, process and purify the fume, but also promote the air convection circulation when the closed burner is burning, so that the combustion is more complete, and one machine has multiple effects.
