Reference numeral 9A denotes a flap attached to the outlet 9 for controlling the vertical direction of the cool / hot air blown from the outlet 9. Unit 10 is a blade unit for controlling the left and right wind direction. The drain pan 6 and the outlet 9 are integrally formed as shown in FIG.

Here, the blade section 10 will be described in detail with reference to FIGS.

FIG. 2 is an explanatory top view of the disassembled blade section 10 of the air conditioner according to the embodiment of the present invention. FIG.
FIG. 1 is an explanatory cross-sectional view of an air outlet of an air conditioner showing an embodiment of the present invention. FIG. 4 is an explanatory bottom view showing a procedure for attaching and detaching the blade unit 10 of the air conditioner according to the embodiment of the present invention.

The blade section 10 includes a direct-acting blade section 11 directly driven by a motor 11A, a detachable blade section 13 connected and driven via an interlocking section 11B of the direct-acting blade section 11 and the direct-acting blade section 11, and And a fixing portion 14 for fixing the detachable blade portion 13.

The direct-acting blade section 11 includes a motor 11A,
A blade 11C driven by a motor 11A, a fixed portion 11D rotatably supporting the blade portion 10, and an interlocking portion 11B connecting the blade 11C and the detachable blade portion 13
It is composed of

The detachable blade portion 13 has a base 13A fitted with a claw (not shown) of the outlet 9 and a plurality of blades 13B rotatably supported by the base 13A at intervals.
And each of the blades 13B
And an interlocking plate 13 </ b> C that rotates in the left-right direction. The blade 13B at the left end of the detachable blade portion 13 is connected to the blade 11C of the direct acting blade portion 11 via the interlocking portion 11B.

The blade 13B and the interlocking plate 13C are integrally formed of a PP resin or the like, so that assembly can be facilitated.

Since the blade unit 10 is configured as described above, by preparing a remote controller, a user can operate the wind direction of the air conditioner with the remote controller.

Here, the attachment and detachment of the blade section 10 will be described.

The user first turns off the air conditioner,
As shown in FIGS. 3 and 4, the connection of the interlocking portion 11B at the left end of the air outlet 9 of the indoor unit 1 with the detachable blade portion 13 is disconnected (see FIG. 4A).

Next, the fixed portion 14 at the lower center of the outlet 9
(See FIG. 4B).

Next, the blades 13B at both ends of the detachable blade portion 13 at the lower portion of the outlet 9 are held with both hands and removed while pulling forward (see FIG. 4C).

At this time, a microswitch 15 is provided at the outlet 9 on the lower surface of the left end of the detachable blade section 13 so that the user may accidentally forget to turn off the power of the air conditioner. There is provided control means for turning off the power supply by the operation of the power supply 15 (see FIG. 3).

For mounting the blade section 10, the above-described method may be reversed.

By removing the blade portion 10 and turning the flap portion 9A downward as described above, it is possible to easily clean the blower fan 5 from the air outlet 9.

Here, control of the flap portion 9A and the blade portion 10 when the operation of the indoor unit 1 of the air conditioner is started will be described.

FIG. 5 is an explanatory sectional view showing a state in which the blade portion 10 of the air conditioner according to the embodiment of the present invention is rotated so as to block the air outlet.

When the indoor unit 1 starts operating, as shown in FIG. 1, the flap portion 9A is turned obliquely upward (toward the suction port) from the stop position, and as shown in FIG. It rotates about 70 degrees in the blowing direction and stops at the right side from the stop position so as to block the lower part of the outlet (anti-suction port side).

Next, the blower fan 5 rotates and the wind discharged from the outlet 9 is blown in the direction of the arrow in FIG. 1, and a part of the wind is again sent to the indoor unit 1 via the suction panel 2B (suction port). Inhaled. At this time, the blade portion 10 is provided at a lower portion of the outlet 9 (on the side opposite to the inlet) and blocks the lower portion of the outlet, so that direct blowing of wind into the conditioned room is reduced.

By blowing air for several minutes as described above, the amount of air blown into the conditioned room through the blade section 10 is reduced, and the indoor unit 1 at the start of operation of the air conditioner is reduced.
The dust in the interior is prevented from being discharged into the harmonized room.

As a result, dust in the indoor unit 1 is collected by the air filter 7 and the air cleaning filter 8 of the indoor unit 1. After a few minutes, the flap section 9A and the blade section 10 are controlled and rotated to appropriate positions for cooling / heating / dehumidifying operations.

Here, control of the flap portion 9A and the blade portion 10 during the dehumidifying operation of the indoor unit 1 of the air conditioner will be described.

The indoor unit 1 at the time of the dehumidifying operation continues the operation with the control positions of the flap unit 9A and the blade unit 10 at the start of the operation described above.

As described above, the amount of wind that passes through the blade portion 10 and blows out to the lower part of the conditioned room is reduced by performing the blowing, and the dehumidified wind during the dehumidifying operation of the indoor unit 1 is generated in the conditioned room. It is possible to perform comfortable dehumidification without blowing downward, without causing the user to feel a so-called cool wind feeling.

If a part of the heat exchanger 4 of the indoor unit 1 functions as a condenser, a more comfortable dehumidifying operation can be performed without changing the room temperature.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention.
