Abstract
Systems, devices, and methods for electrically disconnecting a battery of battery-powered swimming pool cleaners or other swimming pool equipment based on water sensing are described. An example system may include a sensing circuit to detect the presence of water, a power circuit to direct power to an electrical load, and a disabling circuit. The disabling circuit may be configured to receive a signal from the sensing circuit, and, in response, disable the power circuit from powering the electrical load.
Claims35
A system for battery-powered swimming pool cleaners or other swimming pool equipment, comprising:
- a sensing circuit to detect the presence of water;
- a power circuit electrically connected to the sensing circuit and configured to direct power to an electrical load;
- and
- a disabling circuit electrically connected to the sensing circuit and the power circuit, and configured to:
- receive a signal from the sensing circuit;
- and
- responsive to receiving the signal, disable the power circuit from powering the electrical load.
A circuit board for battery-powered swimming pool cleaners or other swimming pool equipment, comprising:
- a sensing circuit comprising a pair of probes to detect the presence of a liquid;
- a power circuit to power an electrical load;
- an electrical interrupter to interrupt flow of electricity to the power circuit;
- and
- a crowbar circuit to cause the electrical interrupter to interrupt the flow of electricity to the power circuit responsive to receiving a signal from the sensing circuit.
A battery-powered underwater pool cleaning device, comprising:
- a compartment that defines an interior volume;
- a power source disposed within the interior volume and configured to power the battery-powered underwater pool cleaning device;
- and
- circuitry electrically connected to the power source and disposed within the interior volume, and configured to:
- detect the presence of water in the interior volume;
- and
- disable the power to the battery-powered underwater pool cleaning device.
A method for battery-powered swimming pool cleaners or other swimming pool equipment, comprising:
- detecting water intrusion within a compartment of a battery-powered device;
- and
- responsive to detecting the water intrusion, activating a disabling circuit configured to cause an interrupting circuit to interrupt flow of electricity from a battery of the battery-powered device.
