Specifically, the exhaust pipe 17 is sealingly connected with the air guide disc 12, and the exhaust pipe 17 is connected with the air volume adjusting assembly 16. The cooking cavity 11 has three working states: when the gas volume passing through the air volume adjusting assembly 16 is the first volume, the cooking cavity is in the first working state; when the gas volume passing through the air volume adjusting assembly 16 is the second volume, the cooking cavity is in the second working state; and when the gas volume passing through the air volume adjusting assembly 16 is the third volume, the cooking cavity is in the third working state. The first volume is greater than the second volume, and the second volume is greater than the third volume.

[0047] ​The air volume adjusting assembly 16 can be an electromagnetic air volume adjusting valve or a mechanical adjusting valve. When the air volume adjusting assembly 16 is a mechanical adjusting valve, it includes an air exhaust support 161, an air exhaust adjusting piece 162, an air outlet rotating piece 163, a decorative cover 164, a spring buckle column 165, and a spring buckle column spring 166. The lower end of the air exhaust support 161 is tubular and is sealingly connected to the air outlet of the air exhaust pipe 17. The upper part of the air exhaust support 161 is formed with a cylindrical assembly cavity. The air outlet rotating piece 163 is rotatably arranged in the assembly cavity of the upper part of the air exhaust support 161. The assembly cavity of the air exhaust support 161 is provided with an air exhaust hole 1611 that is in communication with the lower end. The air exhaust adjusting piece 162 is sealingly arranged in the air exhaust hole. The air exhaust adjusting piece 162 is provided with a plurality of air holes 1621 that are the same or different in diameter. Correspondingly, the air outlet rotating piece 163 is also provided with a plurality of through holes 1631 that are the same or different in diameter. When the air outlet rotating piece 163 rotates in the assembly cavity, the different through holes 1631 correspond to the different air holes 1621, so as to adjust the exhaust steam volume. See Figs. 14 and 15. Figure 1 、 13 The spring buckle column 165 and the spring buckle column spring 166 are installed in the assembly cavity of the upper part of the air exhaust support 161 and are used to position the rotation angle of the air outlet rotating piece 163. The air outlet rotating piece 163 is provided with an adjusting handle 1632. In this embodiment, the air exhaust adjusting piece 162 is provided with two air holes 1621, and the air outlet rotating piece 163 is correspondingly provided with two through holes 1631. The air outlet rotating piece 163 is an adjusting driving plate. By applying an external force to the adjusting handle 1632, the air outlet rotating piece 163 is rotated to be in the first position, the second position, or the third position. When the air outlet rotating piece 163 is in the first position, the two through holes 1631 of the air outlet rotating piece 163 are completely corresponded to the two air holes 1621 of the air exhaust adjusting piece 162 and are in conduction. At this time, the inside of the cooking cavity is in the first working state. The air volume adjusting assembly exhausts the largest amount of air, so that the food can be dry and crisp. When the air outlet rotating piece 163 is in the second position, only one of the two through holes 1631 of the air outlet rotating piece 163 is corresponded to one of the air holes 1621 of the air exhaust adjusting piece 162 and is in conduction, and the other is not in conduction. At this time, the inside of the cooking cavity is in the second working state. The air volume adjusting assembly exhausts moderate amount of air, so that the food can be baked while appropriately retaining moisture. When the air outlet rotating piece 163 is in the third position, one of the two through holes 1631 of the air outlet rotating piece 163 is completely closed, and the other is partially closed and partially in conduction. At this time, the inside of the cooking cavity is in the third working state. The air volume adjusting assembly exhausts the smallest amount of air, so that the steam or hot air can be maximally gathered.

[0048] The gas flow adjusting assembly 16 can also be replaced by other mechanical gas flow adjusting valves capable of adjusting the gas flow, for example, the gas flow adjusting assembly 16 comprises a circular valve plate 16a, which is provided with only one gas outlet 16ab, which is an arc-shaped outlet, as shown in Figure 19 As shown in the figure, the upper part of the valve plate 16a is provided with an adjusting driving plate 16b capable of adjusting the gas outlet area of the gas outlet 16ab. The adjusting driving plate 16b is a sector, the center of which coincides with the center of the valve plate 16a and can rotate around the center of the valve plate 16a. With the rotation of the adjusting driving plate 16b, the sector-shaped adjusting driving plate 16b can partially or completely cover the gas outlet 16ab, thereby changing the gas flow of the gas outlet 16ab. The adjusting driving plate can be manually adjusted or adjusted by a driving motor. In another preferred embodiment, the driving motor 165 is connected with a flat adjusting driving plate 163', which drives the rotation of the adjusting driving plate, as shown in Figure 16 、 17 As shown in the figure, the exhaust adjusting member 162' is provided with only one gas outlet 1621', which is an arc-shaped outlet. The inner diameter of one side of the arc-shaped gas outlet gradually decreases to the other side, forming a gas outlet with gradually changing inner diameter. The gas outlet rotating member 163' is an adjusting driving plate, which is also provided with only one through hole 1631' with the same inner diameter as the largest inner diameter of the gas outlet 1621'. When the gas outlet rotating member 163' is in the first position, the through hole 1631' is in communication with the largest inner diameter of the gas outlet 1621', at which time the air flow of the gas flow adjusting valve is the largest, so that the inside of the cooking cavity is in the first working state. When the adjusting driving plate is in the second position, the through hole 1631' is in communication with the middle part of the gas outlet 1621', at which time the air flow of the gas flow adjusting valve is medium, so that the inside of the cooking cavity is in the second working state. When the adjusting driving plate is in the third position, the through hole 1631' is in communication with the smallest inner diameter of the gas outlet 1621', at which time the air flow of the gas flow adjusting valve is the smallest, so that the inside of the cooking cavity is in the third working state.

[0049] The machine body is also provided with an electric control module for controlling the working states of the steam generating assembly and the hot air assembly. The electric control module is provided with a pure frying and baking working mode, at which time the electric control module controls the hot air assembly to work and controls the steam generating assembly to be closed. The hot air is sent into the cooking cavity, and the number of the gas passing through the gas flow adjusting assembly is adjusted so that the inside of the cooking cavity is in one of the above-mentioned three working states, so that the food in the cooking cavity is processed to be cooked by the hot air.

[0050] Or / and, the electric control module is provided with a simple steaming working mode, at this time, the electric control module controls the steam generating assembly to work, the electric control module controls the hot air assembly to be closed, the steam is sent into the cooking cavity, the amount of steaming is adjusted through the air amount adjusting assembly, so that the inside of the cooking cavity is in one of the above three working states, so that the food in the cooking cavity is processed to be cooked through the steam;

[0051] Or / and, the electric control module is provided with a mixed working mode, at this time, the electric control module controls the steam generating assembly to work, the electric control module controls the hot air assembly to work, the steam and the hot air are sent into the cooking cavity, the amount of gas is adjusted through the air amount adjusting assembly, so that the inside of the cooking cavity is in one of the above three states, so that the food in the cooking cavity is processed to be cooked through the steam and the hot air, at this time, the second discharge amount of steam is moderate, and the food can be baked while appropriately retaining moisture.
