Abstract

Disclosed herein is a air conditioner. The air conditioner a housing including a suction port and a discharge port, a heat exchanger provided inside the housing, a blower fan configured to suction air through the suction port, pass and heat-exchange the air through the heat exchanger, and then discharge the air through the discharge port, and a sub-flow path that suctions and guides some air around the discharge port using a suction force of the blower fan to control the flowing direction of the air discharged from the discharge port.

First claim

The invention claimed is:

1. An air conditioner comprising:
a housing including a suction port through which air is suctioned and a discharge port through which the air suctioned through the suction port is discharged, the housing further including a main flow path formed between the suction port and the discharge port;
a heat exchanger provided on the main flow path and configured to heat-exchange the suctioned air;
a blower fan configured to suction the air through the suction port, move the air suctioned through the suction port to pass through the heat exchanger, and then discharge the heat-exchanged air through the discharge port; and
a sub-flow path disposed external to the housing having a first end provided around the discharge port and a second end connected to inside of the housing,
wherein the blower fan is further configured to suction air around the discharge port through the first end and discharge the suctioned air received through the first end to control a flowing direction of the air discharged from the discharge port.

2. The air conditioner of claim 1 , wherein the first end of the sub-flow path is an inlet port configured to suction the air around the discharge port and the second end of the sub-flow path is an outlet port configured to discharge the air suctioned through the inlet port to the inside of the housing.

3. The air conditioner of claim 2 , further comprising a switch provided on the sub-flow path and configured to adjust an opening degree of the sub-flow path.

4. The air conditioner of claim 3 , wherein the inlet port is provided at a radially outer side of the discharge port on the discharge port and in response to opening of the sub-flow path by the switch, the flowing direction of the air discharged from the discharge port is changed toward the radially outer side of the discharge port.

5. The air conditioner of claim 2 , wherein the outlet port is provided in an upper portion of the housing, which is adjacent to the blower fan.

6. The air conditioner of claim 1 , wherein the blower fan suctions air from both sides thereof in a direction of a rotation axis of the blower fan and discharges the air in a radial direction of the blower fan.

7. The air conditioner of claim 2 , wherein the blower fan is configured such that one side of the blower fan in a direction of a rotation axis of the blower fan faces the suction port and an other side opposite to the one side faces the outlet port of the sub-flow path.

8. The air conditioner of claim 2 , further comprising a damper provided on the sub-flow path and configured to adjust an opening degree of the sub-flow path.

9. The air conditioner of claim 8 , wherein the inlet port is provided at a radially outer side of the discharge port on the discharge port and in response to opening of the sub-flow path by the damper, the flowing direction of the air discharged from the discharge port is changed toward the radially outer side of the discharge port.
