According to the electric cooker control method provided by the embodiment, the temperature of the inner pot 11 is detected, the pot cover 20 is opened relative to the pot body 10 when the temperature of the inner pot 11 is higher than the preset temperature, so that the phenomenon that bubbles are generated in the pot during continuous high-power heating and food overflow is avoided, the bubble destruction in the pot is accelerated by controlling the opening of the pot cover, the occurrence of the phenomenon that the overflow is easy to occur in the cooking process is reduced, and the pot cover 20 is closed after the pot cover is opened for the preset time, so that the heat loss is avoided, and the heating efficiency is reduced; in addition, the user can continuously heat with high power, the cooking time is shortened, and the user experience is improved.
Specifically, when the temperature of the inner pot 11 is higher than the preset temperature, the controlling the pot cover 20 to open includes:
controlling the locking mechanism to release the locking state of the pot cover 20;
the opening and closing mechanism is controlled to drive the cooker cover 20 to open.
Specifically, the method further comprises the following steps:
the critical position of the pot cover 20 is detected, and when the pot cover 20 reaches the first position and/or the second position, the action of the opening and closing mechanism is stopped.
According to the electric cooker control method provided by the embodiment, the critical position of the cooker cover 20 is detected, so that the action of the opening and closing mechanism is stopped when the cooker cover is opened in place and locked in place, and the phenomenon that the cooker cover is damaged due to the fact that the motor continuously rotates and the movement of the cooker cover exceeds the limit is avoided.
The bulb 22 continuously detects the temperature of the inner pot 11, and controls the pot cover 20 to open when the temperature of the inner pot 11 is again greater than the preset temperature, and so on.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
