ABSTRACT:
A water appliance detection and cut off apparatus is provided including a water entry conduit for receiving water from a water source. A pan is provided having a bottom face and a lip coupled thereto and extending upwardly therefrom for defining an open top and an interior space into which the water appliance is stored. A water ball valve is connected to the water entry conduit. In use, the ball valve has a closed orientation upon at least the instantaneous receipt of an activation signal wherein water is prevented from flowing to the water appliance and an open orientation upon at least the instantaneous receipt of a deactivation signal wherein water is allowed to flow to the water appliance. At least one water sensor is situated within the interior space of the pan and is adapted to generate the activation signal upon the detection of water within the pan, wherein the water sensor is connected to the water ball valve for transmitting the activation signal thereto upon the detection of water thereby precluding water from flowing to the water appliance. A D-flip flop having an input is connected to the water sensors for continuously transmitting the activation signal at an output thereof upon at least the instantaneous receipt thereof until the receipt of the deactivation signal at a clear input thereof. Next provided is an audio alarm connected to the output of the D-flip flop for emitting an audible noise only during the receipt of the activation signal. Finally, a reset switch is connected to the clear input of the D-flip flop and the water ball valve for transmitting a deactivation signal thereto upon the depression thereof for resuming the flow of water to the water appliance.
