As the fan rotates, a negative pressure area is formed inside the fan, so that the pressure at the periphery of the fan is far less than the pressure of the peripheral gas, and the gas flows from a high-pressure area to a low-pressure area. Therefore, the gas in the oven flows into the fan from the circle of vent hole in the center of the guide plate, then the fan rotates to accelerate the flowing gas and throw the gas out along the radial direction, and the gas flows out along the circular arc from the upper end and the lower end of the guide plate. The arc shape of the two sides of the guide plate is beneficial to the farther the gas can flow, and the heat generated by the side pipe is brought to the farther position. Through the circular arc design, the hot-blast bottom surface flow about attaching the oven as far as possible of guide, can furthest take out the oven heat with the wind like this, be favorable to the oven homogeneity to promote.

The distance between gas molecules is large due to the high energy of the hot gas flow. The gas with low density is light, and the hot gas flow rises. Therefore, shortening the length of the first arc segment 13 can increase the airflow rate in the middle space while ensuring the airflow rate in the upper space of the liner 2. Like this, can make the baked food of different positions in inner bag 2 be heated evenly, promote user and use experience.

Optionally, the air deflector further comprises a first wind deflector strip 15 and a second wind deflector strip 16. The first weather strip 15 is located on a first vertical side of the fence body 12; the second wind blocking strip 16 is positioned at a second vertical side of the fence body 12; wherein, first weather strip 15 and second weather strip 16 all include the fixed part and the portion of keeping out the wind 18 of perpendicular setting, and the fixed part is used for fixed mounting, and portion of keeping out the wind 18 perpendicular to baffle body 12 to form the space between messenger's baffle and inner bag 2, some air current blows off from the fan and upwards blows off through first circular arc section 13 through the space, and another part air current blows off from the fan and downwards blows off through second circular arc section 14 through the space.

When the guide plate is installed on the inner container 2, a gap is formed between the guide plate body 12 and the side wall of the inner container 2, and the width of the gap is the width of the wind shielding part 18. The gap is used to form a wind tunnel. The air flow in the oven is blown out along the arc sections at the upper and lower sides through the gap after passing through the guide plate body 12 and sucking into the fan. In this way, not only can the air flow direction be better controlled, but also the air flow velocity is improved.

Optionally, the guide plate body is further provided with a plurality of second through holes 10, the plurality of second through holes 10 are regular hexagonal through holes, and the plurality of second through holes 10 are arranged in a honeycomb structure; wherein, the box body 1 comprises a door body, and the second through hole 10 is positioned at the side of the door body.

Because the oven is provided with the heat preservation cotton on all surfaces except the door body, the closer the oven door body is, the lower the temperature is in the use process of the oven. In order to adjust the temperature uniformity of the oven better, a circle of second through holes 10 arranged in a honeycomb structure are added on the guide plate close to the door body, so that more fluid can flow out close to the door body.

And (3) performing CFD simulation calculation on the oven by using fluid simulation software to solve the temperature field inside the oven and solve the temperature uniformity inside the oven. And taking the inner part of the oven inner container 2 as a simulation calculation fluid domain, and setting temperature measuring points according to the number of layers of the gridiron in the oven. Taking the oven of the present embodiment as an example, three layers of baking trays are placed in the oven. 9 temperature measuring points are arranged on each layer, the temperature measuring points are cylindrical, the size of the cylinder is close to that of the moon cake, the property of the cylinder is set to be almost heat-insulating material, and the cylinder is used for simulating food in the baking tray. And performing fourth-order fitting on the change relation between the air heat conductivity coefficient and the temperature by using matlab. And respectively calculating the temperature fields in the ovens with the two air guide plate structures by using simulation software, and extracting the temperature at the temperature measuring point. The temperature of the temperature measuring point is the average temperature of the cylindrical surface. And calculating the average temperature of nine temperature measuring points of each layer according to layers, calculating the temperature variance and standard variance of the layer, and using the variance and variance as the judgment basis of the temperature uniformity. The temperature uniformity of a single layer of the oven is judged by using the variance and the standard deviation of each layer, and the temperature uniformity of the whole oven is judged by using the results of 27 points of the whole oven. From the experimental results, it can be seen that the temperature variance and standard deviation of the asymmetric opening mode are both smaller than the variance and standard deviation of the symmetric opening. According to the meaning of variance and standard deviation, smaller variance means that the group data fluctuates less. This makes it possible to determine that the temperature uniformity is good even when the variance is small. From the results, when the heating pipe 8 is arranged on only one side, the temperature difference of all parts in the oven is large, and the temperature uniformity is very poor. The further away from the heating tube 8, the lower the temperature. And a fan and a heating pipe 8 are additionally arranged on the other side of the oven, so that the uniformity of the temperature inside the oven can be improved. And the temperature uniformity of the asymmetric pore-forming mode is better than that of the symmetric pore-forming mode.
