When the fan module 3 is started, the negative pressure generated by the air inlet of the fan module 3 will suck the gas in the return air pipeline 12 out and discharge the sucked gas through the air outlet 52. Due to the negative pressure suction of the fan module 3, the high-temperature gas in the baking cavity 11 is sucked into the return air pipeline 12 for discharge. At the same time, due to the decrease of the air pressure in the baking cavity 11, the external cold air will be sucked into the baking cavity 11 through the air inlet 51 along the air inlet pipeline 13.

The pressing cylinder 74 presses the sealing door plate 75 to the inlet and outlet. When the product needs to be put into or taken out of the baking cavity 11, the pressing cylinder 74 is reset, so that the sealing door plate 75 is separated from the outer wall of the oven body 1 and a certain air clearance is formed. Then the driving cylinder 71 is driven to push the sliding plate 73 upwards, so that the sealing door plate 75 moves upwards, thereby exposing the inlet and outlet, facilitating the feeding and discharging of the product. After the product is put into the baking cavity 11, the driving cylinder 71 is reset, so that the sealing door plate 75 moves downwards to the height corresponding to the inlet and outlet, and then the pressing cylinder 74 is started to press the sealing door plate 75 to the oven body 1, thereby closing the inlet and outlet, avoiding the high-temperature hot gas from the inlet and outlet during the heating and baking process, thereby affecting the baking effect, and avoiding the hot gas from causing burns to the surrounding operators.

The ventilation net plate 91 and the wind volume adjusting plate 92 are both provided with a plurality of ventilation holes 911. The wind volume adjusting plate 92 moves up and down closely to the ventilation net plate 91.

[0034] When the ventilation holes 911 on the wind volume adjusting plate 92 close to the air inlet pipeline 13 side correspond to the ventilation holes 911 on the ventilation net plate 91, the air flow can directly pass through the ventilation holes 911, thereby entering the baking cavity 11 with the maximum wind volume and wind speed, so as to meet the effective drying and cooling work of the product. When the wind volume adjusting plate 92 is moved, the ventilation holes 911 on the wind volume adjusting plate 92 and the ventilation holes 911 on the ventilation net plate 91 are gradually dislocated, thereby reducing the flux of the ventilation holes 911, so as to control the wind volume and wind speed of the air flow entering the baking cavity 11.

In the process of cooling and temperature reduction, the temperature drop in the baking cavity 11 can be accelerated. When the wind volume adjusting plate 92 is moved, the ventilation holes 911 on the wind volume adjusting plate 92 and the ventilation holes 911 on the ventilation net plate 91 are gradually dislocated, thereby reducing the flux of the ventilation holes 911, so that more gas remains in the baking cavity 11. In the process of heating and baking, the hot air flow can be concentrated in the baking cavity 11, so as to improve the drying efficiency of the product in the baking cavity 11.

[0036] In some embodiments, the air inlet side of the ventilation net plate 91 close to the air inlet pipeline 13 side is provided with a plurality of air direction adjusting plates 93. The upper and lower ends of the ventilation net plate 91 are bent outward to form a folded edge. The air direction adjusting plate 93 is provided with a mounting hole 912 corresponding to the air direction adjusting plate 93 on the upper and lower folded edges of the ventilation net plate 91. The rotating shaft of the air direction adjusting plate 93 penetrates into the mounting hole 912. By arranging the air direction adjusting plate 93 and changing the angle of the air direction adjusting plate 93, the air direction of the air inlet pipeline 13 entering the baking cavity 11 can be offset to the direction of the air direction adjusting plate 93, so as to guide the air flow to the position of the product, thereby improving the drying and cooling effect.
