Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, and more specifically to an upper air inlet burner. Background Art

[0002] The existing burners are basically circular in shape, and their appearance is relatively conventional and durable. However, after the flame comes out of the fire hole, it burns directly upward, and the heat also diffuses upward, resulting in relatively less heat in places without flames, and uneven heat distribution. For example, the Chinese patent authorization announcement number is CN203703969U, which discloses a toothed fire hole type outer fire cover for a concentrated energy burner, including an outer fire cover body with an inner hole, a gas mixing chamber is provided on the lower side of the outer fire cover body, and a plurality of bar-shaped teeth are provided at the lower part of the outer fire cover body, and toothed fire holes arranged obliquely relative to the horizontal direction are formed between adjacent bar-shaped teeth; an oblique fire hole unit is provided on the inner wall of the middle part of the outer fire cover body, and the oblique fire hole unit includes a plurality of oblique fire holes arranged in a ring shape on the outer fire cover body, and the oblique fire holes are arranged obliquely relative to the axial direction of the inner hole; a flame stabilizing groove is provided on the inner wall of the upper part of the outer fire cover body, and a flame stabilizing through hole arranged along the vertical direction is provided on the inner side of the flame stabilizing groove, and one end of the flame stabilizing through hole is connected to the flame stabilizing groove, and the other end of the flame stabilizing through hole is connected to the gas mixing chamber. This patented structure has a certain flame stabilization effect, but the disadvantage is that the heat distribution is not uniform enough and the thermal efficiency is relatively low. Therefore, it is necessary to further improve the existing technology. Summary of the invention

[0005] As a further illustration of the above scheme, the pot rack has a vertical surface, which has a height difference from the fire hole of the outer fire cover, which can effectively increase the heat exchange area and prevent heat from escaping from the bottom, thereby improving thermal efficiency.

[0006] Furthermore, the vertical surface is located on the inner circle of the pot support, and the vertical surface is lower than the fire hole of the outer fire cover.

[0007] Furthermore, the fire holes of the outer fire cover are arranged obliquely upward, and the inner side of the outer fire cover is provided with a concave-convex surface arranged along the circumferential direction.

[0012] The utility model adopts an upper air inlet burner structure which is mainly composed of an air distribution plate, an outer fire cover, a central fire cover and a pot rack. The outer sides of the outer fire cover and the central fire cover are provided with protrusions of a toothed structure, which can realize dynamic collision of heat during combustion, making the heat distribution more uniform. The heat forms heat exchange with the vertical surface of the pot rack, contacts the bottom of the pot after being reflected by the arc surface of the pot rack, thereby making the heat distribution more uniform and the combustion efficiency higher.
