Problems solved by technology

[0003] The existing bottom air intake burners usually have the following defects: 1. The structure of the base and the injection tube is integrated and manufactured by casting process. Due to the special geometric shape of the injection tube, it is generally impossible to implement finishing
As a result, the resistance of the inner fire ejection is too large, which is not conducive to improving the heat flow of the inner fire
3. The parameter setting of the inner and outer fire cover fire holes is unreasonable, and the diameter of the fire cover is blindly increased in order to increase the heat flow

Abstract

The invention discloses a lower air inlet gas burner for a cooking appliance. The lower air inlet gas burner comprises a base and a fire cover, and the fire cover comprises an outer fire cover and aninner fire cover; the outer fire cover is provided with outer fire holes, and the inner fire cover is provided with inner fire holes; both the outer fire cover and the inner fire cover are arranged onthe base, and the base is provided with ejector pipes including an inner fire ejector pipe and an outer fire ejector pipe; the outer fire ejector pipe is provided with an outer fire nozzle, and the inner fire ejector pipe is provided with an inner fire nozzle; the base and the ejector pipes are of separate structures, and the ejector pipes are in threaded connection with the base; the base is manufactured through an aluminum die casting technology, and the ejector pipes are manufactured through a machining technology; finish machining of the ejector pipes is achieved, so that the surfaces ofthe inner walls of the ejector pipes are smooth, and the resistance of the ejector pipes to mixing flow is reduced; the ejection effect is improved, and the expected primary air coefficient can be achieved; and combustion is more sufficient.

Description

technical field [0001] The invention belongs to the technical field of integrated stoves, and in particular relates to a bottom air intake gas burner for a stove. Background technique [0002] Integrated stove, also known as environmental protection stove or integrated environmental protection stove in the industry, integrated stove is a kitchen appliance that integrates multiple functions such as range hood, stove, disinfection cabinet, storage cabinet, etc. It has the advantages of space saving and good fume extraction effect. , energy saving, low consumption and environmental protection. The stove in the integrated stove is a kitchen appliance that is directly heated by gas fuels such as liquefied petroleum gas, artificial gas, and natural gas. The burner of existing cooking range all belongs to atmosphere type burner except infrared burner. Divided according to the technical scheme, the existing burners mainly include upper air inlet burners and lower air inlet burners...
