Embodiment Construction

[0023] Hereinafter, an example of the compressor of the present invention will be shown and described in detail with reference to the drawings. figure 1 It is a perspective view showing the appearance of an air compressor, figure 2 It is a block diagram showing a schematic configuration of an air compressor. The air compressor 1 is schematically composed of a tank unit 2 , a compressed air generating unit 3 , a motor unit (motor unit) 4 , a control circuit unit 5 , and an operation circuit unit 6 .

[0024] The tank part 2 has a storage tank 8 for storing compressed air. Compressed air at a constant pressure generated by the compressed air generating unit 3 is stored in the storage tank 8 . The air compressor 1 according to the present embodiment is characterized in that the pressure of the storage tank 8 is changed according to the usage status of the drive tool.

[0025] A plurality of compressed air outlets 9 are provided in the storage tank 8 . In this embodiment, a h...

Abstract

The invention provides an air compressor, which can control the drive of an electric motor unit and inhibit the increasing of temperature at the same time. The air compressor includes a tank unit, a compressed air generating unit, a motor unit, a driving current generating unit, a control unit and a temperature detecting unit. The tank unit stores a compressed air. The compressed air generating unit generates the compressed air to be stored in the tank unit. The motor unit drives the compressed air generating unit. The driving current generating unit generates a driving current of the motor unit. The control unit drives the motor unit by controlling the driving current generating unit. The temperature detecting unit detects a temperature of the driving current generating unit. The control unit changes the driving current of the motor unit by controlling the driving current generating unit based on the temperature detected by the temperature detecting unit.

Description

technical field [0001] The present invention relates to an air compressor, and more specifically, to an air compressor that uses a converter unit and an inverter unit to drive a motor unit that generates compressed air stored in a tank. Background technique [0002] Conventionally, an air compressor that supplies compressed air to a driving tool such as a nail gun using compressed air has been widely used at a construction site or the like. The air compressor generates compressed air from the compressed air generating unit by driving the motor unit, and stores the generated compressed air in the tank unit. A structure is formed in which stored high-pressure compressed air is reduced to a predetermined pressure by a pressure reducing valve and supplied to a driving tool (for example, refer to Patent Document 1). [0003] In work such as a construction site, the air compressor is often installed outdoors. For example, in the midsummer of scorching sun, the air compressor is ...
