Detailed Description

As shown in fig. 1 to 4, the utility model provides a flue mechanism of an electric oven, which comprises an outer box 2, an inner box 4 of the electric oven installed in the outer box 2, a smoke outlet 9 arranged on the inner box 4 of the electric oven, an inner box and outer box flue connecting pipe 6 installed on the smoke outlet 9, a flue pipe 1 installed on the inner box and outer box flue connecting pipe 6, and a flue pipe 1 installed outside the outer box 2, wherein smoke in the electric oven is discharged from the flue pipe 1.

The high-temperature-resistant smoke sensor 10 passes through the outer box 2 and is arranged on the inner wall of the inner box 4 of the electric oven, the high-temperature-resistant smoke sensor 10 is used for detecting the PM value of furnace smoke in the inner box 4 of the electric oven, the inner box flue connecting pipe 6 is internally provided with a flue air door 7 which is movably arranged by matching with the micro stepping motor 5 through the shaft 8, the micro stepping motor 5 is arranged on the outer wall of the outer box 2, the execution controller 3 is arranged on the side wall of the outer box 2, and the micro stepping motor 5 and the high-temperature-resistant smoke sensor 10 are electrically connected with the execution controller 3.
