ABSTRACT:
Device for closing and automatically opening a cover of a cooking instrument, such as a grill and griddle, which includes a timing unit to determine the time for which the cooking instrument will function. The device includes an electromagnet for keeping the cover in closed and one or more springs for actuating opening of the cover, i.e., the springs are biased to open the cover. In operation, the closing position of the cover is detected, e.g., by a microswitch, and the electromagnet is activated in order to keep the cover closed. The electromagnet is controlled by the timing unit such that, when the cover is closed, the electromagnet is activated and the cover remains closed, and the electromagnet is deactivated after the time preset by the timing unit so that the cover is automatically opened through the bias of the springs.
