The door frame 1 includes two L-shaped door pillars 10 arranged opposite each other, a middle back plate 11 fixedly connected between the two L-shaped door pillars 10, and a panel 12 fixedly connected between the two L-shaped door pillars 10. A window 120 is opened on the panel 12. A cover plate 13 is detachably connected to the middle back plate 11. The cover plate 13 divides the window into an upper door window 121 and a lower door window 122. The upper door panel 2 and the lower door panel 3 are both slidably connected between the two L-shaped door pillars 10 along the Z-axis direction. The first door panel driving mechanism 4 and the second door panel driving mechanism 5 are both arranged inside the cover plate 13 and are used to drive the upper door panel 2 and the lower door panel 3 to move up and down, respectively.

[0020] Its working principle is as follows: installed on the front side of the baking chamber of a double-layer oven, the cover plate 13 is located at the position of the two baking chamber partitions. By setting the first door panel drive mechanism 4 and the second door panel drive mechanism 5 inside the cover plate 13, the empty space of the oven partition is well utilized, which can reduce the thickness and size of the oven door. The upper door panel 2 and the lower door panel 3 are driven by the first door panel drive mechanism 4 and the second door panel drive mechanism 5 respectively to open and close the upper door window 121 and the lower door window 122. The first door panel drive mechanism 4 and the second door panel drive mechanism 5 can be maintained by removing the cover plate 13, which reduces the maintenance difficulty.

[0021] Based on the above embodiments, the first door panel driving mechanism 4 includes a first servo motor 40, a first rotating shaft 41, and two first chains 42 fixedly connected to the middle back plate 11. A first bearing seat 43 is provided on one side of each of the two L-shaped door pillars 10. The first rotating shaft 41 is connected between the two first bearing seats 43 via bearings. The first servo motor 40 is drive-connected to the first rotating shaft 41. A second bearing seat 44 is provided at the top of each L-shaped door pillar 10. A first sprocket 440 is rotatably connected to the second bearing seat 44. Second sprockets 410 are connected to both ends of the first rotating shaft 41. The first chains 42 are connected between the first sprockets 440 and the second sprockets 410. First clamping assemblies 20 are provided on all four sides of the upper door panel 2, and the first clamping assemblies 20 are fixed to the first chains 42. The door panel drive mechanism 5 includes a second servo motor 50, a left bushing 51, a right bushing 52, and two second chains 53, which are fixedly connected to the middle back plate 11. The left bushing 51 and the right bushing 52 are respectively sleeved on both ends of the first rotating shaft 41 and connected to the first rotating shaft 41 through bearings. The second servo motor 50 is connected to the left bushing 51 and the right bushing 52 for transmission. The bottom end of the L-shaped door post 10 is provided with a third bearing seat 54.
