Abstract
A smart power switch for a swimming pool vacuum having a battery powered motor for driving a propeller within a vacuum head to create thrust and suction; the power switch including a microprocessor combined with two integrated motor-driven integrated circuits for driving the motor at different speeds and for detecting and clearing motor jams. Red, green and blue LED indicators notify the user of the state of the motor and motor driver. The microprocessor detects spikes in motor current two determine a motor jam and operates the motor driver to control the motor, including stopping and reversing the motor, to clear an obstruction in the vacuum head.
Claims8
A swimming pool vacuum apparatus comprising:
- a vacuum head including a vacuum housing surrounding an interior thrust channel between a bottom open mouth and a top discharge opening structured for attachment of a catch bag thereto;
- an electrically powered motor supported within the thrust channel of the vacuum housing and having a propeller fitted thereto, and the motor being structured and disposed for driving rotation of the propeller in a first direction to create an upward thrust force through the thrust channel, and the motor being further structured and disposed for driving rotation of the propeller in an opposite second direction to create a reverse direction thrust force downwardly through the thrust channel;
- and
- a smart power switch between an electric power source and the motor for controlling operation of the motor and driven rotation of the propeller at different speeds and in both the first direction and the opposite second direction, and the smart power switch being further structured and disposed for detecting an obstruction against rotation of the propeller, and the smart power switch controlling operation of the motor and rotation of the propeller upon detecting an obstruction in order to clear the obstruction with the propeller.
