Wherein, in a state that the second cooking container 30 is mounted on the base 10 in place, the first steam valve 41 is switched to an open state, thereby communicating the outside with the second cooking cavity 301, and the steam in the second cooking container 30 can be discharged to the outside from the first steam valve 41; under the state that the second cooking container 30 is not installed on the base 10 in place and/or the second cooking container 30 is separated from the base 10, the first steam valve 41 is switched to the closed state, so that the outside and the second cooking cavity 301 are disconnected, and thus, the steam in the second cooking container 30 cannot be discharged from the first steam valve 41, and the scald-proof effect is realized.

It should be understood that the "state that the second cooking container 30 is mounted in place on the base 10" means that the second cooking container 30 is fitted on the base 10 with a precise fitting position, in which the air inlet 303 of the second cooking container 30 is aligned with the second steam discharge part 122. The "state where the second cooking container 30 is not mounted on the base 10" refers to a state where the second cooking container 30 is fitted on the base 10 and the fitting position is inaccurate, for example, a state where the second cooking container 30 is not completely separated from the base 10 in a process of removing the second cooking container 30 from the base 10 after cooking is completed.

In some embodiments, the base 10 has a first stopping portion 151, and the first stopping portion 151 stops the second steam valve 42 in a state that the second cooking container 30 is mounted in place on the base 10, thereby switching the first steam valve 41 to an open state. Thus, after the second cooking container 30 is mounted on the base 10, the first stopping portion 151 can be used to stop the first steam valve 41, so as to ensure that the first steam valve 41 can be reliably switched to the open state, thereby realizing the communication between the second cooking cavity 301 and the outside, and discharging the steam in the second cooking container 30.
