Abstract
An apparatus for combination with a standard range having burners thereon and a power line connected thereto is provided and senses the current through the power line for a pre-set level, times the current once the pre-set level is reached, interrupts the current, signals when interruption of the current has occurred and includes controls for controlling the timing and the signalling in the apparatus.
Claims8
In combination with a standard range having burners thereon, oven elements therein, and a power line connected thereto, an apparatus in electrical communication therewith for monitoring said range comprising:
- sensing means for sensing a preset level of electrical current through said power line;
- timing means for timing said current;
- whereby said sensing means initiates said timing means when said sensing means senses said preset level of electrical current;
- disconnect means for interrupting said current;
- signaling means providing a signal when said disconnect means interrupts said current, whereby said signal means is activated by said disconnect means;
- electronic control means for controlling said timing means and said signaling means whereby said timing means can be adjusted to time for different predetermined amounts of time.
