[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] like Figure 1As shown in the figure, a cooking appliance combustion assembly includes a burner seat 1, a central burner cap 2, and an outer ring burner cap 3.

[0021] The burner seat 1 includes an outer ring air intake cavity 11 with a lower opening, a central air intake pipe 12 and a central burner cap seat 13 provided on the top plate, a radial gas passage 14, and an outer ring gas groove 15. The radial gas passage 14 has an acute angle α with the horizontal plane below. The bottom plate of the outer ring gas groove 15 is provided with an inverted frustum-shaped flow guiding portion 151, and the gas outlet end of the radial gas passage 14 is communicated with the inverted frustum-shaped flow guiding portion 151. With such a design, the gas in the radial gas passage is slowly flowed and split by the inverted frustum-shaped flow guiding portion 151, effectively preventing the generation of eddy currents, and the gas is evenly distributed and the flame is stable.

[0022] The outer ring burner cap 3 includes an inverted frustum-shaped inner ring wall plate 31 and a column frustum-shaped outer ring wall plate. The column frustum-shaped outer ring wall plate includes a top frustum-shaped portion 321 and a cylindrical portion 322. A plurality of combustion hole groups 33 and flame stabilizing grooves 34 are provided on the top frustum-shaped portion 321, and the flame stabilizing grooves 34 are communicated with the inner cavity of the outer ring burner cap 3. The inverted frustum-shaped inner ring wall plate 31 plays a role in concentrating energy and gathers the flame of the central burner cap at the bottom of the pot.

[0023] The central burner cap 2 is buckled with the central burner cap seat 13, and the outer ring burner cap 3 and the outer ring gas groove 15 are buckled.

[0024] The axis of the combustion hole of the combustion hole group 33 has an acute angle β with the horizontal on the radial outer side.

[0025] As a further improvement of the present invention: a vertical air intake hole 35 is provided on the inner shoulder at the intersection of the top frustum-shaped portion 321 and the cylindrical portion 322, and the vertical air intake hole 35 is communicated with the flame stabilizing groove 34.

With such a structure, the gas at the gas outlet ends of two adjacent radial gas passages is prevented from interfering with each other.

[0027] The number of the combustion hole groups 33 corresponds to the number of the radial gas passages 14.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention.
