Abstract

An air conditioner includes a main body including a body fan, a heat exchanger, and a body housing. A ventilation hose connects the main body to outdoor air. A ventilation module is attached to an outer side of the body housing, and includes a ventilation fan. The ventilation module switches between an exhaust mode in which indoor air is exhausted to the outdoors through the ventilation hose and an air supply mode in which outdoor air is supplied to the main body through the ventilation hose.

First claim

What is claimed is:

1. An air conditioner comprising:
a main body, configured to be located in an indoor environment, including
a body fan located in an interior of the main body, and
a heat exchanger located in the interior of the main body; and

a ventilation module attached to an exterior of the main body, the ventilation module including:
a ventilation hose connecting the ventilation module to an outdoor environment and configured to allow air to flow between the indoor environment and the outdoor environment,
a ventilation fan, and
a module housing configured to accommodate the ventilation fan in an interior of the module housing,

wherein the ventilation module is configured to switch between an exhaust mode in which air from the indoor environment is exhausted to the outdoor environment through the ventilation hose and an air supply mode in which air from the outdoor environment is supplied to the indoor environment through the ventilation hose,
wherein the ventilation fan is provided at a lower portion of the module housing, and
wherein the module housing includes an outlet of the ventilation fan provided at an upper side of the ventilation fan to discharge the air flow upward in the exhaust mode and the air supply mode.

2. The air conditioner of claim 1 , wherein the module housing includes:
a port to which the ventilation hose is coupled,
a module suction port configured to suction air to the module housing, and
a module discharge port configured to discharge air to the indoor environment, and
wherein the main body includes:
a body suction port configured to suction air to the main body, and
a body discharge port configured to discharge air to the indoor environment, and

wherein the module discharge port is located adjacent to the body suction port.

3. The air conditioner of claim 2 , wherein the port is located at an exterior of the main body.

4. The air conditioner of claim 2 , wherein the ventilation module includes
a first damper configured to allow an inlet of the ventilation fan to communicate with one of the module suction port and the port, and
a second damper configured to allow the outlet of the ventilation fan to communicate with one of the port and the module discharge port.

5. The air conditioner of claim 4 , wherein, in the exhaust mode, the first damper is configured to allow the inlet of the ventilation fan to communicate with the module suction port, and the second damper is configured to allow the outlet of the ventilation fan to communicate with the port.

6. The air conditioner of claim 4 , wherein, in the air supply mode, the first damper is configured to allow the inlet of the ventilation fan to communicate with the port, and the second damper is configured to allow the outlet of the ventilation fan to communicate with the module discharge port.

7. The air conditioner of claim 4 , wherein the ventilation module includes,
a suction flow path configured to guide air suctioned through the module suction port to the inlet of the ventilation fan,
a discharge flow path configured to guide air discharged through the outlet of the ventilation fan to the module discharge port, and
a suction/discharge flow path configured to guide air suctioned through the port to the inlet of the ventilation fan, or guide air discharged through the outlet of the ventilation fan to the port.

8. The air conditioner of claim 4 , wherein the first damper includes,
a cylindrical damper body having a bottom surface in a circular shape and a side surface extending from a rim of the bottom surface to be perpendicular to the bottom surface; and a rotation shaft portion formed at a center of the bottom surface to rotate the cylindrical damper body.

9. The air conditioner of claim 8 , wherein the cylindrical damper body includes,
an inner space, a damper inlet formed on the side surface to allow air to be introduced into the inner space, and
a damper outlet formed on a side opposite to the bottom surface to allow air to flow out of the inner space.

10. The air conditioner of claim 4 , wherein the second damper includes,
a shielding plate and a rotation shaft portion formed at one edge of the shielding plate to rotate the shielding plate.

11. The air conditioner of claim 4 , wherein the first damper includes
a shielding plate and a rotation shaft portion formed at one edge of the shielding plate to rotate the shielding plate.

12. An air conditioner comprising:
a main body, configured to be installed in an indoor environment, including
a heat exchanger, and
a body fan; and

a ventilation module, coupled to the main body, including:
a ventilation fan,
a module housing configured to accommodate the ventilation fan in an interior of the module housing, the module housing including:
a module suction port to suction air from the indoor environment to the module housing,
a module discharge port to discharge air to the indoor environment, and
a port to suction air from an outdoor environment or discharge air to the outdoor environment,

a first damper configured to allow an inlet of the ventilation fan to communicate with one of the module suction port and the port, and
a second damper configured to allow an outlet of the ventilation fan to communicate with one of the port and the module discharge port,
wherein the ventilation fan is provided at a lower portion of the module housing, and
wherein the outlet of the ventilation fan is provided at an upper side of the ventilation fan to discharge the air flow upward in an exhaust mode and an air supply mode.

13. The air conditioner of claim 12 , wherein the ventilation module is configured to switch between the exhaust mode in which air from the indoor environment is exhausted to the outdoor environment and the air supply mode in which air from the outdoor environment is supplied to the indoor environment.

14. The air conditioner of claim 13 , wherein, in the exhaust mode, the first damper is configured to allow the inlet of the ventilation fan to communicate with the module suction port, and the second damper is configured to allow the outlet of the ventilation fan to communicate with the port.

15. The air conditioner of claim 13 , wherein, in the air supply mode, the first damper is configured to allow the inlet of the ventilation fan to communicate with the port, and the second damper is configured to allow the outlet of the ventilation fan to communicate with the module discharge port.

16. The air conditioner of claim 12 , wherein the first damper includes
a cylindrical damper body having a bottom surface in a circular shape, and
a side surface extending from a rim of the bottom surface to be perpendicular to the bottom surface, and
a rotation shaft portion formed at a center of the bottom surface to rotate the cylindrical damper body.

17. The air conditioner of claim 16 , wherein the cylindrical damper body includes,
an inner space,
a damper inlet formed on the side surface to allow air to be introduced into the inner space, and
a damper outlet formed on a side opposite to the bottom surface to allow air to flow out of the inner space.

18. The air conditioner of claim 12 , wherein the second damper includes a shielding plate and a rotation shaft portion formed at one edge of the shielding plate to rotate the shielding plate.

19. A ventilation apparatus comprising:
