Inner flame energy-concentrating riser pipe type gas burner

Abstract

The invention discloses an inner flame energy-concentrating riser pipe type gas burner, which comprises a big fire burner, a small fire burner, a mixing tube of the big fire burner, a positioning tube of the small fire burner, and a water collector. An inner ring of an annular shell of the big fire burner is an inverted frustum which forms an angle between 20 and 80 DEG with a horizontal plane, and 1 to 5 fire exhaust holes are formed on the inner ring. One end of the mixing tube of the big fire burner is connected with the annular shell and communicated with an inner cavity of the annular shell, while the other end is communicated with a big fire nozzle which is arranged on the lower part of the water collector. The small fire burner comprises a frustum cap shell and an inner cavity of the frustum cap shell, wherein 1 to 5 fire exhaust holes are formed on external side face of the frustum cap shell, and the inner cavity of the frustum cap shell is communicated with a small fire nozzle which is positioned on the lower part of the water collector by a mixing tube of the small fire burner. The inner flame energy-concentrating riser pipe type gas burner has the advantages of reasonable structure, high thermal efficiency, material conservation, convenient processing, excellent energy-saving effect, less exhaust emission and the like.

Description

technical field

[0001] The invention relates to a gas burner, in particular to an internal flame gas burner. Background technique

[0002] With the increasing requirements of modern families for kitchen equipment, the built-in household gas cooker used to inlay on the cooktop has achieved a certain degree of improvement in shape and appearance, but the heart of the gas cooker, that is, the burner, has not. For a big improvement, most factories only refit the traditional horizontal tube atmospheric burner on the bottom shell of the embedded gas stove. Because the primary air intake of this type of burner needs to enter from the vent on the bottom shell when it is working, the burner part cannot be isolated from the bottom shell. cause a lot of trouble. At the same time, when the traditional burner is used as a heating element, the temperature of the cooking surface will be high, especially when the nozzle is tempered due to the boiling overflow blocking the fire hole, the t...
