Title:
AIR COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/220510
Kind Code:
A1
Abstract:
The present invention relates to an air compressor in which the arrangement structure between a filter part and a discharge resistor has been improved to reduce interference between the filter part and the discharge resistor and increase the space utilization of the filter part, thus making the air compressor more compact. The air compressor comprises: a housing; a rotary shaft disposed inside the housing; a compression part that is connected to the rotary shaft and compresses and discharges introduced air; a motor part driving the rotary shaft; a control board for controlling the motor part; and the filter part which filters noise of external power and supplies the external power to the control board, wherein the filter part includes a capacitor assembly connected to an external power source, a transistor connected to the control board, a current sensor assembly connected to the transistor, and a discharge resistor that is connected to the capacitor assembly and discharges the residual charge in the capacitor assembly.
