Abstract

Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.

First claim

What is claimed is:

1. An air conditioner comprising:
an indoor unit including a front panel provided with an air inlet and an air outlet, the indoor unit being configured to suck indoor air through the air inlet and simultaneously discharge air through the air outlet, wherein
the indoor unit includes
a main flap, and
a sub-flap,

the main flap and the sub-flap are coupled to at least one motor so that the main flap and the sub-flap are rotatable simultaneously via the at least one motor,
the main flap is rotatable about a first rotation axis and a second rotation axis spaced apart from each other to change a position of the main flap, and the sub-flap is rotatable about a third rotation axis, separated from the first rotation axis and the second rotation axis, to change a position of the sub-flap, to thereby guide the air discharged from the air outlet in a direction determined by the position of the main flap and the position of the sub-flap, and
an indoor side surface of the main flap is positioned on substantially a same plane as an indoor side surface of the front panel in an operation stop state.

2. The air conditioner according to claim 1 , wherein the third rotation axis is at one end of the sub-flap.

3. The air conditioner according to claim 2 , wherein, as the sub-flap rotates about the third rotation axis, a distance between another end of the sub-flap and a point on the main flap is changed.

4. The air conditioner according to claim 1 , wherein the indoor unit is embeddable in a ceiling and, while the indoor unit is embedded in the ceiling, the first rotation axis is positioned lower than the second rotation axis and the third rotation axis in a control position in which the main flap extends lower than the outlet and controls a direction of air discharged from the air outlet.

5. The air conditioner according to claim 1 , wherein the indoor unit is embeddable in a ceiling and, while the indoor unit is embedded in the ceiling, the first rotation axis is positioned lower than the second rotation axis and the third rotation axis in a closed position in which the main flap closes the air outlet.

6. The air conditioner according to claim 1 , wherein a length of the main flap in an airflow direction is longer than a length of the sub-flap in the airflow direction.

7. The air conditioner according to claim 1 , wherein the indoor unit is embeddable in a ceiling of a room, and the main flap is configured to, while the indoor unit is embedded in the ceiling, close the air outlet while simultaneously covering the sub-flap so that the sub-flap is invisible from the room in the operation stop state.

8. The air conditioner according to claim 1 , wherein:
the main flap includes a flow path forming surface formed on one surface of the main flap,
the sub-flap includes a flow path forming surface formed on a lower surface of the sub-flap,
an air flow path is formed so that the air discharged through the air outlet passes along the flow path forming surface of the main flap and the flow path forming surface of the sub-flap, and
a length of the main flap in an airflow direction is longer than a length of the sub-flap in the airflow direction.

9. The air conditioner of claim 1 , further comprising:
at least one link that couples the sub-flap and the main flap together, so that the sub-flap is rotatable about the third rotation axis in linkage with rotation of the main flap.

10. The air conditioner of claim 1 , further comprising:
at least one link that couples the sub-flap and the main flap together, so that the sub-flap and the main flap are rotatable in linkage with each other via a same motor of the at least one motor.

11. The air conditioner of claim 1 , wherein positions of the first rotation axis and the second rotation axis are movable to change the position of the main flap.

12. An air conditioner comprising:
an indoor unit including a front panel provided with an air inlet and an air outlet, the indoor unit being embeddable in a ceiling of a room and being configured to, while embedded in the ceiling, suck indoor air through the air inlet and simultaneously discharge air into the room through the air outlet, wherein
the indoor unit includes
a main flap rotatable about a first rotation axis and a second rotation axis spaced apart from each other to change a position of the main flap,
a sub-flap rotatable about a third rotation axis, spaced apart from the first and second rotation axes, to change a position of the sub-flap, and
at least one link that links the sub-flap and the main flap together, so that the sub-flap and the main flap are simultaneously rotatable in linkage with each other via a single motor to guide the air discharged from the air outlet in a direction determined by the position of the main flap and the position of the sub-flap, and
an indoor side surface of the main flap is positioned on substantially a same plane as an indoor side surface of the front panel in an operation stop state.

13. The air conditioner of claim 12 , wherein positions of the first rotation axis and the second rotation axis are movable to change the position of the main flap.

14. The air conditioner of claim 12 , wherein the main flap is configured to close the air outlet while simultaneously covering the sub-flap so that the sub-flap is invisible from the room in the operation stop state.

15. An air conditioner comprising:
an indoor unit including a front panel provided with an air inlet and an air outlet, the indoor unit being embeddable in a ceiling of a room and being configured to, while embedded in the ceiling, suck indoor air through the air inlet and simultaneously discharge air into the room through the air outlet, wherein
the indoor unit includes
a main flap rotatable about a first rotation axis and a second rotation axis which are movable and separated from each other, to change a position of the main flap,
a sub-flap rotatable about a third rotation axis to change a position of the sub-flap, and
at least one link that links the sub-flap and main flap together, so that the sub-flap and the main flap are simultaneously rotatable in linkage with each other to guide the air discharged from the air outlet in a direction determined by the position of the main flap and the position of the sub-flap, and

an indoor side surface of the main flap is positioned on substantially a same plane as an indoor side surface of the front panel in an operation stop state.

16. The air conditioner of claim 15 , wherein the main flap is configured to close the air outlet while simultaneously covering the sub-flap so that the sub-flap is invisible from the room in the operation stop state.

17. The air conditioner of claim 15 , wherein the sub-flap and the main flap are rotatable in linkage with each other via a single motor.

18. The air conditioner of claim 15 , wherein positions of the first rotation axis and the second rotation axis are movable to change the position of the main flap.

19. An air conditioner comprising:
an indoor unit having air inlet and an air outlet, the indoor unit being configured to suck indoor air through the air inlet and simultaneously discharge air through the air outlet, wherein
the indoor unit includes
a main flap, and
a sub-flap,

the main flap and the sub-flap are coupled to at least one motor so that the main flap and the sub-flap are rotatable simultaneously via the at least one motor,
the main flap is rotatable about a first rotation axis and a second rotation axis spaced apart from each oth
