The heating principle of flat ovens is to use upper and lower heating tubes to heat the food in the middle. This type of oven can only bake one dish at a time, and its commercial efficiency is low. Convection ovens use hot air circulation to bake multiple dishes at the same time, thereby increasing production. However, if you want to further increase production, general flat fans cannot meet the requirements, and setting up multiple fans takes up a large space.

[0037] The utility model provides an oven.

[0038] See also Figure 1 and Figure 2 In one embodiment of the present invention, the oven comprises:

[0039] Box 100;

Food is placed in the baking cavity, and a fan assembly 300 and a heating tube 400 are arranged in the accommodating cavity to blow heated air into the baking cavity. Specifically, the fan assembly 300 includes a motor, fan blades 320 and a drum 310. The drum 310 is arranged around the fan blades 320. The motor drives the drum 310 to rotate, so that the air flow increases when passing through the drum 310, and the hot air flow directly flows into the baking cavity through the first air outlet 210 and the second air outlet 220, thereby heating the food in the baking cavity and ensuring uniform temperature distribution in the oven. In addition, the arrangement of the drum 310 increases the rotating wind force and ensures the rapid flow of hot air in the oven. The second air outlet 220 is distributed on the back plate 200 away from the central first air outlet 210, so that the hot air flow enters the baking cavity through the first air outlet 210 and the second air outlet 220 at different positions in the accommodating cavity, thereby improving the uniformity of the hot air flow transfer and ensuring the temperature balance of various parts in the oven. The food on each layer of the oven can be fully and evenly heated, avoiding the situation where the food is locally colored quickly or slowly, and improving the baking efficiency of the oven. The heating is carried out by the heating tube 400 and the fan assembly 300, so as to realize the rapid and uniform circulation of the hot air flow. Due to the strong wind force and fast heat distribution, the output of the oven can be significantly improved, that is, more food can be processed and the productivity can be improved.

[0045] In a specific embodiment, the back panel 200 is vertically arranged in the box body 100, and the motor is installed inside the box body 100. On the side corresponding to the back panel 200, a plurality of fan blades 320 are arranged at intervals on the drum 310. The extension direction of the fan blades 320 is the axial direction of the drum 310. When the motor drives the drum 310 to rotate, the wind force generated is greater than that of a flat fan, and it is also more convenient to blow the hot air flow into the baking chamber. In addition, the air outlet end of the drum 310 is aligned with the back panel 200, and a plurality of first air outlets 210 are opened on the back panel 200. The first air outlet 210 is aligned with the fan blades 320, and the second air outlets 220 are distributed at other positions of the back panel 200. Through the arrangement of multiple first air outlets 210 and multiple second air outlets 220, the hot air flow is evenly blown into the baking chamber in the accommodating chamber, and the food in the baking chamber is evenly heated.

[0046] In addition, the position and number of the first air outlet 210 and the second air outlet 220 on the back plate 200 are not limited, as long as the hot air flow can be evenly dispersed at various positions of the back plate 200, it is preferred to set the first air outlet 210 as a plurality of through holes, and the plurality of through holes are arranged along the circumference, and the axis corresponds to the axis of the roller 310, and the second air outlet 220 is arranged at intervals of two in the horizontal direction on the upper part of the back plate 200, and at intervals of five in the horizontal direction on the lower part of the back plate 200, and a second air outlet 220 is arranged on each side of the back plate 200, so that the hot air flow diffuses more evenly.

[0047] In an embodiment of the present invention, the oven further includes an inner liner, which is disposed inside the box body 100.
