The four side wall plates 12, the rear wall plate and the door 20 of the cabinet 10 enclose a closed cooking chamber 122.
In one embodiment, referring to fig. 1 to 4, an electric cooking appliance includes a box 10, a door 20, a door hook 30, a door hook limiting block 40, a first unlocking assembly 50, and a second unlocking assembly 60. The refrigerator body 10 is provided with a mouth portion 11, the door body 20 is openably disposed at the mouth portion 11, a first lock hole 121 is disposed on a side wall plate 12 of the refrigerator body 10, a chamber 122 is disposed inside the side wall plate 12, and the chamber 122 is communicated with the external environment through the first lock hole 121. The door hook 30 is movably disposed on the door body 20, and the door hook 30 can be inserted into the first lock hole 121 or pulled out of the first lock hole 121. The door hook limiting block 40 is in interference fit with the hook body of the door hook 30, and the door hook limiting block 40 is arranged in the cavity 122. The first unlocking component 50 is used for driving the hook body of the door hook 30 to move to a first unlocking position, and when the first unlocking component 50 drives the hook body of the door hook 30 to move to the first unlocking position, the door hook limiting block 40 is separated from the hook body of the door hook 30. The second unlocking assembly 60 is used for locking or unlocking the first unlocking assembly 50, when the second unlocking assembly 60 locks the first unlocking assembly 50, the first unlocking assembly 50 is in an inoperable state, and when the second unlocking assembly 60 unlocks the first unlocking assembly 50, the first unlocking assembly 50 can perform unlocking action.
When the cooking appliance is used, the door body 20 is closed in the mouth portion 11, the door hook 30 is inserted into the first lock hole 121, the hook body of the door hook 30 is in interference fit with the door hook limiting block 40, namely the door body 20 is limited by the door hook limiting block 40 and cannot be opened, meanwhile, the first unlocking assembly 50 is locked by the second unlocking assembly 60, namely the first unlocking assembly 50 is in an inoperable state, the door body 20 is guaranteed not to be opened by misoperation, and the door opening safety is improved. Referring to fig. 4 to 7, when the door body 20 needs to be opened, the second unlocking assembly 60 is acted first, so that the second unlocking assembly 60 releases the first unlocking assembly 50, and then the second unlocking assembly 50 is acted to drive the hook body of the door hook 30 to move to the first unlocking position, when the first unlocking assembly 50 drives the hook body of the door hook 30 to move to the first unlocking position, the door hook limiting block 40 is separated from the hook body of the door hook 30, that is, the door hook limiting block 40 does not abut against the hook body of the door hook 30, and the door body 20 can be opened freely. Therefore, the door body 20 can be opened only by unlocking twice, the door body 20 can be prevented from being opened by misoperation, and the door opening safety is improved.
Further, referring to fig. 1 to 4, the first unlocking assembly 50 includes a door opening button 51 and a rotating link 52. The side wall plate 12 is provided with a key hole 123 for installing the door opening key 51, and the key hole 123 is communicated with the cavity 122.
