ABSTRACT:
The invention relates to a safety control shut-off device for the heating element of a cooking stove. In one embodiment of this safety device, a burner plate of the stove is provided with several declining U-shaped grooves for collecting any spillage or overflow of water from the cooking operations. Water drops collected in the declining grooves are led through a discharge outlet, at the lowest portion of the grooves, and into a water drop detector located beneath the outlet, to complete an electrical circuit, which in turn will actuate and sound an alarm and will also actuate means for disconnecting the fuel source of the plate burner.
