Refrigerator and control method therefor

A control method for a refrigerator, wherein the refrigerator comprises:

• a refrigerator body comprising an ice making chamber defined therein;
• and
• an ice maker disposed in the ice making chamber and comprising:
• a mold shell comprising a first sub-mold shell and a second sub-mold shell;
• a driving mechanism configured to drive at least one of the first sub-mold shell or the second sub-mold shell to move, the first sub-mold shell and the second sub-mold shell cooperatively defining a mold cavity when the first sub-mold shell and the second sub-mold shell move to a closed state;
• and
• a demolding mechanism disposed on at least a side of the mold shell and spaced apart from the mold shell by a predefined distance, the demolding mechanism being configured to eject an ice block in the mold shell when the demolding mechanism comes into contact with the mold shell;
• and
• wherein the method comprises:
• when the refrigerator is powered off, recording an operation currently performed by the ice maker;
• when the refrigerator is powered back on, on a condition that a recorded operation of the ice maker is an ice making operation or a water injection operation, and a flow pulse of injected water is detected when the ice maker performs the water injection operation, determining that water may exist in the mold cavity;
• on a condition that the first sub-mold shell and the second sub-mold shell are in the closed state, determining that water exists in the mold cavity;
• and
• on a condition that the first sub-mold shell and the second sub-mold shell are not in the closed state, determining that no water exists in the mold cavity.

A refrigerator, comprising:

• a refrigerator body, comprising an ice making chamber defined therein;
• an ice maker, disposed in the ice making chamber, and comprising:
• a mold shell comprising a first sub-mold shell and a second sub-mold shell;
• a driving mechanism configured to drive at least one of the first sub-mold shell or the second sub-mold shell to move, wherein the first and second sub-mold shells cooperatively define a mold cavity when the first and second sub-mold shells move to a closed state;
• and
• a demolding mechanism disposed on at least a side of the mold shell and spaced apart from the mold shell by a predefined distance, the demolding mechanism being configured to eject an ice block in the mold shell when the demolding mechanism comes into contact the mold shell;
• a controller, configured to:
• record an operation currently performed by the ice maker when the refrigerator is powered off;
• and
• when the refrigerator is powered back on, determine a water status of the mold cavity based on a recorded operation.
