Device for the closing and automatic opening of the cover of a cooking instrument, especially grills, griddles and the like
First Claim
1. A cooking instrument, comprisinga cover,a device for closing and automatically opening said cover, said device comprisingan electromagnet having an activated condition in which said cover is kept closed and a deactivated condition when said cover is openable,detecting means for detecting when said cover is closed and permitting activation of said electromagnet when the cover is closed in order to keep said cover closed, andat least one spring biased to open said cover;
- anda timing unit arranged to determent the time for which the cooking instrument will function, said timing unit also being arranged to control said electromagnet such that, when said cover is closed, said electromagnet is activated and said cover remains closed, and said electromagnet is deactivated after the time preset by said timing unit such that said cover is automatically opened through the bias of said at least one spring.

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.

9. Device for closing and automatic opening a cover of a cooking instrument which includes a timing unit to determine the time for which the cooking instrument will function, comprising
an electromagnet for keeping the cover closed, said electromagnet having an activated condition in which the cover is kept closed and a deactivated condition when the cover is openable, means for detecting the position of the cover, and at least one spring for actuation opening of the cover, said at least one spring being biased to open the cover, said detecting means detecting the closing position of the cover and permitting activation of said electromagnet in order to keep the cover closed, said electromagnet being controlled by the timing unit such that, when the cover is closed, it remains closed due to the action of said electromagnet and the cover opens after the time preset by the timing unit through the action of said at least one spring and the deactivation of said electromagnet.
