The following description will be made of the automatic moisture removing operation of the steaming and baking all-in-one machine with reference to fig. 1 to 11:

the controller 202 controls the operation of the driving mechanism 18 and the air pump 11 according to the humidity data in the steaming and baking chamber collected by the humidity sensor 203;

when the controller 202 judges that the humidity in the steaming and baking integrated machine is low, the controller 202 commands the air pump 11 to stop pumping air, and commands the driving mechanism 18 to start driving, the driving mechanism 18 drives the moving block 19 to move in a two-dimensional plane in a direction perpendicular to the moving direction of the push plates, the moving block 19 pulls the two connecting blocks 17 to move through the rod body 101, then the moving connecting blocks 17 drive the corresponding push plates 15 to move axially along the moving block, at the moment, the two push plates 15 move in the cavity 120 of the valve body 12 in the opposite direction, and along with the continuous movement of the two push plates 15, the sealing plates 151 on the two push plates 15 are finally attached to each other, in this state, the original cavity 120 of the valve body is blocked by the two attached push plates, hot steam in the steaming and baking integrated machine cannot flow into the hot air exhaust pipeline 22 of the steaming and baking integrated machine 2 through the valve body 12, so that a certain amount of steam is ensured to be in the baking chamber of the steaming and baking integrated machine, and the humidity required by food steaming and baking is satisfied;

when the controller 202 determines that the humidity in the steaming and baking chamber is relatively high, the controller 202 commands the air pump 11 to start air pumping, and commands the driving mechanism 18 to start reverse driving, the action of the driving mechanism 18 causes the reverse action of other mechanisms, finally, two sealing plates 151 attached originally are enabled to move back to back and gradually keep away from each other, the blocked cavity 120 in the valve body 12 is restored to the initial through state again, under the air pumping action of the air pump 11, hot steam in the steaming and baking all-in-one machine flows into the hot air exhaust pipeline 22 of the steaming and baking all-in-one machine 2 to be exhausted after passing through the moisture exhaust pipeline 21 and the valve body 12 of the steaming and baking chamber, thereby the humidity in the steaming and baking chamber is reduced, and the humidity required by food steaming and baking is satisfied.

Referring to fig. 12, the embodiment provides a dehumidifying method of a steaming and baking all-in-one machine, which includes the following steps:

step 1, acquiring humidity data in a steaming and baking integrated machine through a humidity sensor 203;

step 2, the controller 202 makes judgment processing according to the collected humidity data:

when the collected humidity data is greater than or equal to a preset humidity threshold value, the controller 202 commands the exhaust valve structure to open the moisture discharge pipeline 21 of the steaming and baking all-in-one machine to a through state, and commands the air pump 11 to start the air pumping work of the steam in the moisture discharge pipeline 21, so as to discharge the steam in the steaming and baking all-in-one machine to the outer side of the steaming and baking all-in-one machine through the hot air discharge pipeline 22; otherwise, the step 1 is carried out.

It should be noted that the moisture exhaust mechanism and the moisture exhaust method in this embodiment can also be applied to a disinfection cabinet for implementing disinfection based on hot steam.
