AIR CONDITIONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18250801 titled 'AIR CONDITIONER
Simplified Explanation
The abstract describes an air conditioner with an outdoor unit that has a three-phase AC power supply, a compressor, and an inverter circuit. The outdoor unit also includes a driving microcomputer, diode bridges, relays, and an inrush-prevention resistor. After the compressor stops, the microcomputer turns off the relays.
- The air conditioner has an outdoor unit with a compressor and inverter circuit.
- The outdoor unit is powered by a three-phase AC power supply.
- A driving microcomputer controls the inverter circuit.

Original Abstract Submitted
An air conditioner includes an outdoor unit including a three-phase AC power supply, a compressor that compresses a refrigerant, and an inverter circuit that controls the compressor. The outdoor unit includes a driving microcomputer that drives the inverter circuit, a second diode bridge connected to the inverter circuit, a first relay disposed on a first wiring line, a second relay disposed on a third wiring line, an inrush-prevention resistor, and a third relay connected to the first wiring line and the inrush-prevention resistor. After the compressor stops, the driving microcomputer brings the first relay, the second relay, and the third relay into an off state.
