Abstract

An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.

First claim

What is claimed is:

1. An air conditioner comprising:
a main unit having an enclosure defining a first airflow passage extending from a first air inlet to a first air outlet, the first airflow passage containing a heat exchanger generating a cool air or a warm air forming an airflow running out of the first air outlet into a room space;
a horizontal flap located in the first air outlet for a relative positional movement around a horizontal axis, the horizontal flap configured to regulate a direction of the airflow running out of the first air outlet;
a pair of fan units disposed on left and right opposite sides of the first air outlet for a positional movement relative to the main unit around a horizontal axis, the fan units being configured to define second airflow passages, respectively, each extending from a second air inlet open outside the main unit, to suck a room air, to a corresponding second air outlet to blow the room air at room temperature into the room space, each of the second airflow passages being isolated from the first airflow passage of the enclosure; and
a controller unit interlocking a first control signal for establishment of a first predetermined position of the horizontal flap and a second control signal for establishment of a second predetermined position of the fan units to each other.

2. The air conditioner according to claim 1 , further comprising:
a first driving source configured to drive a first blower fan enclosed in the enclosure; and
a second driving source, independent of the first driving source, configured to drive a second blower fan contained in each of the fan units, respectively.

3. The air conditioner according to claim 2 , wherein the horizontal flap is configured to guide a discharge of the airflow in a horizontal direction.

4. The air conditioner according to claim 3 , wherein the fan units are configured to take a position directing air in the horizontal direction or an ascendant direction.

5. The air conditioner according to claim 4 , wherein the fan units are configured to take a position designed to discharge air from a position higher than the first air outlet in the horizontal direction or an ascendant direction.

6. The air conditioner according to claim 2 , wherein the horizontal flap is configured to guide a discharge of the airflow in a descendant direction, and the fan units are configured to take a position directing air in a horizontal direction or an ascendant direction.

7. The air conditioner according to claim 6 , wherein the fan units are configured to take a position designed to discharge air from a position higher than the first air outlet in the descendant direction or higher.

8. The air conditioner according to claim 1 , wherein the second air outlets are located forward of the first air outlet of the main unit.

9. The air conditioner according to claim 1 , wherein the controller unit is configured to output the first control signal to a first driving source of the horizontal flap and the second control signal to a second driving source of each of the fan units.

10. The air conditioner according to claim 9 , wherein the first driving source moves the horizontal flap to the first predetermined position in response to the first control signal and the second driving source moves each of the fan units to the second predetermined position in response to the second control signal.
