Description

Centripetal polar flame burner and kitchen range Technical Field The invention relates to the technical field of combustors, in particular to a centripetal polar flame combustor and a kitchen range. Background The burner is an indispensable kitchen utensil in life, and the cooking is accomplished to the heating of pan through the burner realization. The outer ring fire hole on the outer ring fire cover of the burner in the prior art is usually vertical or simply inclined, so that the flame direction is not ideal at the bottom angle of the cooker, the bottom of the cooker is difficult to be heated uniformly, the heights of the bottom of the cooker from the fire holes of the outer rings are inconsistent after the cooker is placed, local overheating or insufficient heating is caused, the thermal efficiency is low, and the energy consumption is higher. The outer ring fire hole on the outer ring fire cover lacks an effective protection structure, liquid and sundries easily enter the inner part of the outer ring fire hole when the pot overflows or is clean, so that the normal combustion is influenced, the service life is shortened, meanwhile, the flow velocity of mixed gas is easily caused to be too low due to unreasonable structural parameter design of the outer ring fire hole, tempering phenomenon is caused, and certain potential safety hazard exists. Meanwhile, the gas and air of the burner in the prior art are unevenly mixed, and because the air supply depends on natural injection, the mixing effect is greatly influenced by factors such as air pressure, the combustion is insufficient easily, harmful gases such as carbon monoxide are generated, the heat load adjusting range is narrow, and the efficiency is limited. When the existing kitchen range supplies air, the supply proportion of fuel gas and air cannot be accurately matched in real time according to the combustion state, so that under different firepower gears, heat is taken away by excessive air, or the combustion is insufficient due to excessive fuel gas, and low emission and low energy consumption cannot be realized while the thermal efficiency is ensured.
