Description
Technical Field
The invention relates to a burner of a gas cooker, in particular to a burner with double-stage injection for a gas cooker and a cooker applying the burner.
Background
At present, the upper air inlet gas stoves in the market are platform type gas stoves and embedded type gas stoves, wherein the burner of the embedded type gas stove is of a single-channel upper air inlet structure, gas enters through a channel, the firepower of the gas is controlled by a valve, and the gas of an inner fire ring cannot be used independently. In order to solve the problems that a single channel does not have independent central fire and the heat load is small, a Chinese patent with the application number of CN98120026.5 (with the publication number of CN1212348A) discloses a gas burner which has simple structure and can independently adjust the central fire and the outer ring fire, that is, such burners are generally provided with a central injector and an outer ring injector, but such gas burners have been found in experiments to have unsatisfactory combustion performance, uneven velocity of primary air supplied to the central flame front and the outer flame front, because the air suction of the central ejector and the outer ring ejector is uneven, the flame length of the central fire and the flame length of the outer ring fire are different due to the incomplete mixing of the gas and the primary air, meanwhile, the ejector pipe is limited by the height of the upper air inlet burner and cannot be too long, so that the channel resistance is large, yellow flame is easy to appear when the power is high, and particularly, the yellow flame is more obvious when the power is low. Although lower air inlet burner compares upper air inlet burner, and it draws and penetrates the pipe and be difficult to receive the restriction of combustor height, and difficult yellow flame that takes place, nevertheless lower air inlet burner has cubical switchboard door flameout problem (because in the one moment of cubical switchboard door, present negative pressure state in the cooking utensils chassis easily, lead to flame to withdraw the combustor, especially when minimum fire, lead to little fire to extinguish easily). Because the primary air and the secondary air of going up the air inlet combustor all flow in from the panel, it can solve the flameout problem of cubical switchboard door, but goes up the air inlet because the structure is restricted, and the injection ability is not enough, leads to the load of combustor can't do greatly usually. In order to avoid the technical problems that the small fire is easy to extinguish and the load of the upper air inlet burner cannot be large, the existing upper air inlet and/or lower air inlet needs to be further improved.
