Abstract

The invention discloses an upper air inlet combustor. The upper air inlet combustor at least comprises a combustor main body and a combustor mounting base, wherein a ring-shaped gas mixing cavity is additionally arranged at the outer side of the combustor main body; an included-angle type outer ring ejector is arranged on the bottom non-center part of the combustor, so that the length of the outerring ejector is remarkably increased; and on the combustor mounting base, two outer ring spray nozzles share one spray nozzle mounting base and one fuel gas channel, so that flow loss, in the spray nozzle base, of gas is reduced, and the outer ring spray nozzle mounting base is more compact in structure. According to the gas stove disclosed by the invention, two openings which correspond to the spray nozzle mounting base on the combustor mounting base are formed in a liquor containing disc. The upper air inlet combustor has the beneficial effects that: combustion performances are remarkably improved, thermal load of the gas stove can be 4.0-4.5 kW, and heating efficiency can meet primary energy efficiency requirements; and the combustor main body adopts aluminum die casting or plate stretch-forming. The gas stove can realize an ultrathin structure, is free of holes in a stove surface; and the combustor is convenient to dismount, and is easier to clean and maintain.

Description

Technical field

[0001] The invention relates to a burner and a gas stove, in particular to an upper air inlet burner and a gas stove equipped with the upper air inlet burner. Background technique

[0002] A gas stove equipped with an air inlet burner, the air required for combustion is replenished from the top of the stove panel, and there is no need to open air holes on the cabinet, so it is very popular in the market. However, due to the limitation of the appearance and installation structure of the upper air inlet burner, the ejector of the burner is relatively short, resulting in a relatively small thermal load of the burner, which limits the development of gas stoves equipped with upper air inlet burners.

[0003] The ejector of the upper air inlet burner is divided into two types: upright ejector and non-upright ejector. For burners with vertical ejector, the nozzle mounting seat is mostly cup-shaped. On gas stoves equipped with this type of burner, after removing the upper ...
