Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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; and a control circuit, wherein the control circuit selects one of a plurality of modes, each of the plurality of modes having a rotational speed of the motor and a reference restart pressure, the plurality of modes includin…
