Description

Technical Field

[0001] This utility model relates to a burner for a gas stove, and more particularly to an inner flame vortex burner. Background Technology

[0002] Currently, most gas stove burners used in the domestic stove market are made of brass. Their structure is mostly aluminum injector tube, aluminum burner head, aluminum mixing plate, and copper large and small burner caps. This has disadvantages such as complex and cumbersome structure, high material cost, high process cost, and emission pollution from casting. Patent No. 20081012956.1 introduced an inner flame burner made of stainless steel sheet metal, but due to the influence of the structure, the overall heat load of the burner is relatively small, which cannot meet the current user demand for high power and high thermal efficiency.

The burner is an irregularly shaped shell with a centrally protruding annular cone shape. Large flame ejector tubes are provided on both sides and connected to it, forming a double-ejector structure. A protruding short flame groove and a recessed long flame groove are provided on the central annular cone surface. The long flame groove is intersecting the short flame grooves, i.e., the long flame groove is located in the middle of the two short flame grooves. A protruding upper flame-stabilizing groove and a recessed lower flame-stabilizing groove are provided at the end of the inner ring of the central annular cone's large flame mixing chamber. Two segmented grooves and two segmented ribs are provided at the bottom of the central annular cone. A connecting hole is provided on the outer edge, and two positioning grooves are provided at the outlet of the large flame ejector tube.

[0005] The inner flame vortex burner has 10-50 short fire slots and 10-50 long fire slots on its central annular conical surface, which are evenly distributed along the circumference. The oblique angle A is 5-50 degrees and the upward angle B is 10-60 degrees.

[0006] The aforementioned inner flame vortex burner comprises an upper shell and a lower shell. The upper shell is an irregularly shaped plate with a central annular conical protrusion, and large flame injector upper shells are respectively located on its left and right sides. The lower shell is an irregularly shaped plate with a central annular conical protrusion and a concave shape, and large flame injector lower shells are respectively located on its left and right sides. It also features an upwardly protruding short flame groove, an upwardly protruding flame stabilizing upper groove on the inner ring, two segmented grooves at the end of the central annular conical bottom large flame mixing upper cavity, and connecting grooves on the outer edge. The holes are respectively located on the upper shell, the recessed long fire groove, the recessed flame stabilizing groove in the inner ring, the two segmented ribs at the end of the large fire mixing lower cavity in the middle annular cone shape, and the connecting holes on the outer edge are located on the lower shell. After the upper shell and the lower shell are combined accordingly, the outer edge of the upper shell wraps around the outer edge of the lower shell and is riveted to form the burner. After the upper shell and the lower shell of the large fire ejector tube are combined accordingly, the outer edge of the upper shell of the large fire ejector tube wraps around the outer edge of the lower shell of the large fire ejector tube and is riveted to form the large fire ejector tube.
