When the kitchen ware burner works, the fan 3 is started to drive air to enter the air inlet pipe 2, meanwhile, the first gas pipe 4 supplies gas into the air inlet pipe 2, the second gas pipe 15 supplies gas into the traditional cooking range 14, and as the igniter is integrated in the traditional cooking range 14, the traditional cooking range 14 can be firstly ignited under the gas supply of the second gas pipe 15, and then flame contacts the gas discharged from the gas discharge hole 12 and ignites other areas of the upper surface of the stove body 1, so that the stove body 1 works. Due to the arrangement of the metal fiber net 16, a rigid and porous plate is formed, so that gas distribution is more uniform, and the uniformity of heat conduction is improved; and after the metal fiber net 16 is heated, heat can be radiated, and a part of heat is released in a radiation mode, so that the overall combustion efficiency of the cooking range is improved.

As shown in fig. 3 and 4, in order to fully mix the gas in the first gas pipe 4 (here shown in fig. 1) with the air in the inlet pipe 2, a turbulence generator 5 for improving the mixing efficiency of the air and the gas is further provided in the inlet pipe 2. The gas inlet pipe 2 comprises a first pipeline 21 and a second pipeline 22 which are connected with each other, and the end part of the first pipeline 21 is communicated with the interior of the furnace body 1; the end part of the second pipeline 22 is communicated with the air outlet of the fan 3; the diameter of the inner wall of the first pipeline 21 is larger than that of the inner wall of the second pipeline 22, and the first gas pipe 4 is disposed on the circumferential surface of the second pipeline 22 and is communicated with the inside of the second pipeline 22. A cross-shaped fixing frame 61 is fixed in the first pipeline 21, and the fixing frame 61 is positioned at the joint of the first pipeline 21 and the second pipeline 22.
