Abstract

An indoor unit and an air conditioner configured so that each outlet and each flap can be easily identified. An indoor unit (1) is provided with outlets (32a-32d) which discharge air-conditioning air toward the interior space, and also with flaps (35a-35d) having substantially the same shape, the flaps (35a-35d) being respectively disposed at the outlets (32a-32d) and capable of individually changing the discharge directions of the air-conditioning air. Sign sections (60a-60d) which are different from each other are formed either in the vicinities, respectively, of the outlets (32a-32d) or on the flaps (35a-35d), respectively.

Claims

1. An indoor unit comprising:

a plurality of outlets that discharges air-conditioning air towards a room space;

a plurality of flaps of substantially the same shape respectively disposed at the plurality of outlets, and capable of individually changing the discharge direction of the air-conditioning air;

a plurality of different sign sections respectively provided either in the vicinity of each of the plurality of outlets or on each of the plurality of flaps such that the plurality of flaps are simultaneously and distinctively visually identifiable from the each other; and

a controller that receives control signals from a remote control that accepts operations entered to change the positions of the plurality of flaps, the remote controller including a display section that displays which of the plurality of sign sections is currently selected, simultaneously with information indicative of the discharge direction of the air-conditioning air at the outlet indicated by the selected sign section,

wherein each of the plurality of outlets or each of the plurality of flaps has a different number sign sections provided in the vicinity thereof.

2. The indoor unit according to claim 1, wherein the sign sections are three-dimensionally provided as raised portions or recessed portions.

3. The indoor unit according to claim 1, wherein the sign sections are provided by being printed or by attaching stickers.

6. The indoor unit according to claim 1, wherein the sign sections have a gloss portion or a light emitting portion.

7. The indoor unit according to claim 1, further comprising a panel that has an intake and a plurality of outlets,

wherein the sign sections are formed on the panel in positions respectively corresponding to the plurality of outlets.

8. The indoor unit according to claim 7, wherein the plurality of outlets are disposed along side portions of the panel.

9. The indoor unit according to claim 8, wherein the intake is disposed on the inner side of the plurality of outlets.

10. The indoor unit according to claim 9, wherein the sign sections are formed on the intake side of the plurality of outlets.

11. The indoor unit according to claim 9, wherein the sign sections are formed opposite from the intake with respect to the plurality of outlets.

12. The indoor unit according to claim 1, wherein the sign sections are respectively formed on the plurality of flaps.

13. An air conditioner comprising:

the indoor unit of any one of claims 1 to 12; and

a remote controller that accepts operations entered to change the positions of the plurality of flaps, the controller including a display section that displays which of the plurality of sign sections is currently selected, simultaneously with information indicative of the discharge direction of the air-conditioning air at the outlet indicated by the selected sign section.

14. The air conditioner according to claim 13, wherein the remote controller enables the positions of the plurality of flaps to be individually changed so as to change the discharge direction of the air-conditioning air at the plurality of outlets.

15. The air conditioner according to claim 13, wherein the remote controller enables the positions of the plurality of flaps to be changed at once so as to change the discharge direction of the air-conditioning air at the plurality of outlets.

16. The air conditioner according to claim 15, wherein the remote controller enables the positions of the selected ones of the plurality of flaps to be changed at once so as to change the discharge direction of the air-conditioning air at the plurality of outlets.

17. The air conditioner according to claim 13, wherein the display section simultaneously displays information indicative of the discharge directions of the air-conditioning air from all of the plurality of outlets.

18. The air conditioner according to claim 13, wherein the remote controller is connected to the indoor unit via a wire.

4. An indoor unit comprising:

a plurality of outlets that discharges air-conditioning air towards a room space;

a plurality of flaps of substantially the same shape respectively disposed at the plurality of outlets, and capable of individually changing the discharge direction of the air-conditioning air; and

a plurality of visually different sign sections respectively provided either in the vicinity of each of the plurality of outlets or on each of the plurality of flaps such that the plurality of flaps are simultaneously and distinctively visually identifiable from the each other; and

a controller that receives control signals from a remote control that accepts operations entered to change the positions of the plurality of flaps, the remote controller including a display section that displays which of the plurality of sign sections is currently selected, simultaneously with information indicative of the discharge direction of the air-conditioning air at the outlet indicated by the selected sign section,

wherein each of the visually different sign sections has different characters, figures, or combinations of characters and figures.

5. The indoor unit according to claim 4, wherein the sign sections corresponding to the vicinity of the plurality of outlets or to the plurality of flaps include ordered signs arranged in order either clockwise or counterclockwise.

19. An indoor unit comprising:

a panel including a plurality of outlets that discharges air-conditioning air towards a room space;

a plurality of flaps of substantially the same shape respectively disposed at the plurality of outlets, and capable of individually changing the discharge direction of the air conditioning air; and

a plurality of different sign sections respectively provided, on the panel, outside of the respective outlets such that the plurality of flaps are simultaneously and distinctively visually identifiable from the each other; and

a controller that receives control signals from a remote control that accepts operations entered to change the positions of the plurality of flaps, the remote controller including a display section that displays which of the plurality of sign sections is currently selected, simultaneously with information indicative of the discharge direction of the air-conditioning air at the outlet indicated by the selected sign section,

wherein each of the respective outlets has a different number of sign sections provided outside thereof.
