[0048] The first steam discharge port 810 and / or the second steam discharge port 820 are provided with a moisture discharge adjusting mechanism 700, as shown in Figure 7 The pure steaming function needs a smaller steam discharge port, the baking function needs a larger steam discharge port, and the tender baking function also needs a smaller steam discharge port. According to the cooking demand, the steam amount in the cooking inner cavity can be adjusted in the embodiment, so that the cooking demand of different cooking functions can be met, and the phenomenon that the steam outlet 510 is too small, the pressure in the cooking inner cavity is too large, and the door is difficult to close and has an abnormal sound during the cooking process can be avoided.

[0049] The moisture discharge adjusting mechanism 700 comprises a push plate 710 which is in sliding connection with the box body 100, a push rod 720 which is connected with the push plate 710, and a cover plate 730 which is connected with the push rod 720, the push plate 710 slides relative to the box body 100 to drive the cover plate 730 to switch between the first position and the second position, as shown in Figure 8 、 9As shown: in the first position, the cover plate 730 covers the first steam outlet 810 or the second steam outlet 820, and in the second position, the cover plate 730 is arranged in a staggered manner with the first steam outlet 810 or the second steam outlet 820. The embodiment changes the position of the cover plate 730 by pushing the push plate 710 to achieve the adjustment of the moisture discharge, which is a preferred embodiment for easy operation and does not limit the utility model; in order to avoid the impact of air pressure on the cover plate 730, a plurality of air holes 731 are arranged on the cover plate 730. In order to indicate the current steam discharge amount of the user, the embodiment can set a steam discharge amount mark on the top of the box body 100, beside the push plate 710.

[0050] Specifically, the push rod 720 is an elongated rod structure, and the axis position thereof needs to be maintained, so that the cover plate 730 can be covered on the first steam outlet 810 or the second steam outlet 820, and the gap between the cover plate 730 and the first steam outlet 810 or the second steam outlet 820 in the covered state is avoided. In the embodiment, at least two groups of first limiting blocks 150 are arranged on the top of the box body 100, and the push rod 720 is coaxially arranged in the first limiting block 150. In order to realize the positioning of the first position and the second position, at least one group of second limiting blocks 160 is arranged on the top of the box body 100, and the push rod 720 is provided with a first limiting ring 740 and a second limiting ring 750, and the first limiting ring 740 and the second limiting ring 750 are respectively located on the two sides of the second limiting block 160; when the first limiting ring 740 and the second limiting ring 750 respectively abut against the second limiting block 160, the cover plate 730 is respectively located in the first position and the second position.

[0051] When the cover plate 730 is in the first position, the first steam outlet 810 or the second steam outlet 820 has the gas pressure acting on the cover plate 730. In order to avoid the position deviation of the cover plate 730 caused by the impact of the gas, the embodiment sets a locking mechanism to lock the cover plate 730 in the first position when the cover plate 730 is in the first position. Specifically, the push rod 720 is provided with a third locking portion 760, and the top of the box body 100 is provided with a fourth locking portion 170, and the third locking portion 760 and the fourth locking portion 170 are matched and locked. In the embodiment, the third locking portion 760 can be specifically an elastic clamping portion, and the fourth locking portion 170 can be specifically a recess portion, and when the elastic clamping portion is clamped into the recess portion, the positions of the two can be locked; and under the action of external force, the elastic clamping portion can be separated from the recess portion to release the locking.

[0052] The specific working principle of the embodiment is as follows:

[0053] The embodiment can realize the moisture adjustment by pushing the push plate 710: when the small exhaust amount is needed, the push plate 710 is pushed to the first limiting ring 740 and the second limiting block 160 on the push rod 720 to abut and limit, and the cover plate 730 is pushed to the first position; in the first position, the cover plate 730 covers the first exhaust port 810 or the second exhaust port 820, and the exhaust amount is reduced; and in the first position, the third locking part 760 cooperates with the fourth locking part 170 to be locked, so that the cover plate 730 is kept in the first position, as shown in Figure 8 When the exhaust amount needs to be increased, the push plate 710 is pushed backward to the second limiting ring 750 and the second limiting block 160 on the push rod 720 to abut and limit, and the cover plate 730 is pushed to the second position; in the second position, the cover plate 730 completely opens the first exhaust port 810 or the second exhaust port 820, and the exhaust amount is increased, as shown in Figure 9 .
