Electric heating devices are provided in the lower oven shell 12 and / or the upper oven shell 13 corresponding to the cooking cavity.

[0035] An electrical cavity 10 is provided inside the furnace base 11, and a detachable base plate 14 is provided on the bottom surface of the furnace base 11. A control box 2 and a main control box 3, connected as a single unit, are installed inside the electrical cavity 10. The control box 2 and the main control box 3 abut against each other and are connected and fixed by a first connector (not shown in the figure). A first through hole 31 for wires to pass through is provided on the abutting side of the control box 2 and the main control box 3. That is, the control box 2 and the main control box 3 are detachably installed together inside the furnace body 1.

[0036] Specifically, the control box 2 has second ears 21 on both sides, and the second ears 21 have second positioning holes 22 for the second connector (not shown in the figure) to pass through. The furnace body 1 and the second ears 21 are detachably connected and fixed through the second connector and the second positioning holes 22. Preferably, the second connector is a screw. The front sidewall of the control box 2 is exposed on the outer surface of the furnace body 1. The control board 6 inside the control box 2 has a control end 4 on the front sidewall. In this embodiment, the control end 4 is a control knob. The front sidewall of the control box 2 also has a display screen 5. The main control box 3 is located on the back of the control box 2. The back of the control box 2 has a first opening 20 for installing the control board 6. The top surface of the main control box 3 has a second opening 30 for installing the main control board 7. The front sidewall of the main control box 3 has a first through hole 31. The main control box 3 and the control box 2 are connected through the first through hole 31. The control box 2 has a first ear 23 on both sides, and a first positioning hole 24 on the first ear 23. The main control box 3 has a fixing stud 32 corresponding to the first positioning hole 24, and a fixing screw hole 33 on the fixing stud 32. The first connector is a screw, which passes through the first positioning hole 24 and is threadedly connected to the fixing screw hole 33.

[0037] The top surface of control box 2 is higher than the top surface of main control box 3. Main control box 3 is provided with a fixed cover plate 8, which is connected and fixed to main control box 3. The fixed cover plate 8 covers the second opening 30.
