Inverter apparatus provided with dust collecting unit

An inverter apparatus provided with a dust collecting unit, comprising:

• a housing having an air inlet port formed on a lower side of a first surface and an air discharge port formed on an upper side of a second surface;
• an electrical element for an inverter, which is arranged in the housing;
• a first suction member which is disposed inside the housing to allow outside air to flow into the housing through the air inlet port and generate a flow of air discharged through the air discharge port to cool the electrical element;
• and
• a dust collecting unit which is disposed below the air inlet port to remove dust included in the air flowing into the air inlet port,
• wherein the dust collecting unit comprises:
• a first discharge electrode which is negatively charged;
• a dust collection electrode which is spaced apart from the first discharge electrode and positively charged;
• an air flow guide which is formed to extend downward from a periphery of the air inlet port such that the outside air flows past the first discharge electrode and the dust collection electrode before entering the air inlet port;
• and
• a dust tray which is disposed below the dust collection electrode to collect the dust attracted to the dust collection electrode,
• wherein the air flow guide has a circular cross-sectional shape,
• wherein the first discharge electrode is disposed along a central axis of the air flow guide, and the dust collection electrode is disposed along an inner peripheral surface of the air flow guide so as to surround the first discharge electrode,
• wherein the outside air flowing from the lower side of the housing to the upper side of the housing is introduced into an interior of the housing after passing through the dust collecting unit and the air inlet port, and flows upward to be discharged to an exterior of the housing through the air discharge port.
