When the device of the invention works, when the burner 303 sprays flame to the plate body 1 of the energy storage plate in the fire chamber pipe 302, the flame continuously heats the plate body 1, and the flame is transmitted to the plate body 1 near one end of the smoke discharging device 304 through the first through hole 3 and the second through hole 5 of the plate body 1, so that the whole plate body 1 can be uniformly heated, after the plate body 1 of the energy storage plate burns red, the first blades 21 and the second blades 22 which are obliquely arranged are close to the inner wall of the fire chamber pipe 302, so that heat can be continuously transmitted to the fire chamber pipe 302, the temperature of the fire chamber pipe 302 is increased, and meanwhile, the heat loss of the energy storage plate is slower, so that heat energy can be stored in the fire chamber pipe 302 and transmitted to the fire chamber pipe 302, the heat efficiency of the fire chamber pipe 302 is improved, the oil temperature in the oil containing cavity 301 can be kept not easily reduced, and the working efficiency of the frying pan is improved.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that various changes and substitutions are possible within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.

Claims
