[0022] As Figures 3-5 shown, the box body 1 further includes support modules 110 symmetrically arranged on both sides inside the box body 1; every two oppositely arranged support modules 110 form a support module, the support modules are arranged in sequence along the vertical direction inside the box body 1, and an equal gap is left between the bottom of each upper support module and the top of the next support module to form a chute 120, a limit block 130 is arranged at the same gap distance at the top of the first support module inside the box body 1 to form a chute 120 with equal spacing; the product to be processed is placed on the baking rack 8 and slides inward through the chute 120 and is placed in the accommodation cavity for baking and processing and is supported by the lower support module to provide support force, and the baked product also slides outward through the chute 120 and is taken out from the accommodation cavity. The setting of the chute 120 can play a certain role in restricting the displacement of the baking rack 8, so that even if the whole oven shakes, the baking rack 8 and the products on the baking rack 8 will not easily fall off.

[0023] Continue to refer to Figures 3-5 , the baking rack 8 includes a baking tray 810 and a baking net 820, both the baking tray 810 and the baking net 820 are slidably connected to the accommodation cavity of the box body 1 through the chute 120, the baking net 820 is used for baking large pieces or foods that are not easy to drip oil or water, while the baking tray 810 is used for baking scattered and easily dripping foods. The setting of the baking tray 810 and the baking net 820 facilitates users to place different types of products to be processed respectively. At the same time, as a preferred embodiment, when in use, the baking net 820 is placed on the top of the upper support module and the baking tray 810 is placed on the top of the lower support module.
