  • Patent number: 11486600
    Abstract: An air conditioner includes an indoor unit and an outdoor unit. The outdoor unit includes: a DC motor; an inrush-current prevention relay having a coil and a contact provided on a supply line of an AC power supply as a power supply of the outdoor unit, in which the contact is in an electrically-disconnected state when any current does not flow through the coil and is in an electrically-connected state when a current flows through the coil; a PTC connected in parallel to the contact; and a temperature protector provided on a supply line of a relay-driving power supply as a power supply of the inrush-current prevention relay, which is in an electrically-connected state when a temperature of the DC motor is lower than a predetermined temperature, but is in an electrically-disconnected state when the temperature of the DC motor reaches a predetermined temperature or higher.
