Abstract
An air compressor includes a tank unit that stores compressed air, a motor unit that generates compressed air to be stored in the tank unit, a pressure detection unit that detects a pressure value in the tank unit, and a control unit that drives the motor unit when a pressure value in the tank unit detected by the pressure detection unit is equal to or less than a motor start pressure value, and stops the motor unit when the pressure value in the tank unit detected by the pressure detection unit is equal to or greater than a motor stop pressure value. The control unit changes at least either of the motor start pressure value or the motor stop pressure value every time when a predetermined time passed.
Claims8
An air compressor comprising:
- a tank that stores compressed air;
- a motor that is configured to drive the air compressor and generate compressed air to be stored in the tank;
- a pressure sensor that detects a pressure value in the tank;
- and
- a controller that drives the motor when a pressure value in the tank detected by the pressure sensor is equal to or less than a motor start pressure value, and stops the motor when the pressure value in the tank detected by the pressure sensor is equal to or greater than a motor stop pressure value,
- wherein the controller reduces the motor start pressure value and the motor stop pressure value and reduces an output of the motor each time a first predetermined time has passed in a state where the motor is stopped.
