1. An air conditioner comprising:
a housing comprising a cylindrical member, and a discharge port having an arc shape and being formed in a lower portion of the cylindrical member;
a main fan;
a heat exchanger having an arc shape and being between the main fan and an inner peripheral surface of the cylindrical member with respect to a radial direction of the cylindrical member, wherein a discharge flow path is formed inside the housing between an outer peripheral end of the heat exchanger and the inner peripheral surface of the cylindrical member to allow air introduced into the housing by the main fan and exchanging heat with the heat exchanger to flow from the heat exchanger to the discharge port to be discharged through the discharge port, and a guide flow path is formed outside the discharge flow path with respect to the radial direction of the cylindrical member; and
an auxiliary fan in the discharge flow path and configured to suck some of the air discharged through the discharge port into the guide flow path, wherein the guide flow path returns the air sucked by the auxiliary fan into the guide flow path to the auxiliary fan to be blown by the auxiliary fan to the discharge flow path, so as to change a direction of airflow discharged from the discharge port.
