Air Compressor

摘要

An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

1. An air compressor comprising:
a tank configured to accommodate compressed air having a pressure; a compression mechanism configured to supply compressed air to the tank; a motor configured to drive the compression mechanism; a storing unit; and a control circuit, characterized in that: the storing unit stores information indicating a history of an operation state of the air compressor; the control circuit selects one of a plurality of modes, each of the plurality of modes having the rotational speed of the motor and the reference restart pressure, at least one of the rotational speed and the reference restart pressure being different from among the plurality of modes; the control circuit executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the reference start pressure corresponding to the target mode with the pressure of the compressed air and rotates the motor at the rotational speed corresponding to the target mode; and the control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the information.
