Further, the control unit 60 controls the compressor 21, the four-way switching valve 22, the decompressor 25, the fan motor 13 and the flap motor 146.

The ROM 41 stores control programs and various parameters. The ROM 41 further stores the set air volume at various settings, the position of the horizontal flap 144 at the time of powerful operation setting, the swing range, and the like.
The set air volume is an operating air volume that determines the air volume of air blown from the air outlet 143. Specifically, “Shizuka”, “Slight wind”, “Weak”, “Weak wind”, “Weak strong”, “ One of the "strong winds". “SHIZUKA” indicates the driving air volume with the smallest air volume, and “strong wind” indicates the operating air volume with the largest air volume. The control unit 60 selects one of the set air volumes based on a signal from the remote controller 40 described later, and stores the selected set air volume in the RAM 42. And the control part 60 rotates the fan motor 13 so that the air after conditioning of the quantity according to the selected setting air volume may be ventilated indoors.

The infrared sensor 44 transmits information about the direction in which the detected person is present to the control unit 60. It should be noted that human sensing using the infrared sensor 44 may be performed constantly or may be performed at predetermined time intervals.

<Powerful operation with this air conditioner>
Hereinafter, the powerful operation of the air conditioner 1 during the cooling operation and the heating operation will be described.
For example, when the user inputs an instruction to perform a powerful operation from the remote controller 40 during the cooling operation, the control unit 60 of the air conditioner 1 increases the rotational speed of the cross flow fan 12 in order to improve the air conditioning processing capability. In addition to controlling the fan motor 13, the operation frequency of the compressor 21 is controlled.

  In the air conditioner 1 of the present embodiment, in particular, when receiving an instruction input for powerful operation, the control unit 60 controls the direction of the horizontal flap 144 in addition to the above control. For example, during normal cooling operation, air conditioned in a substantially horizontal direction is blown into the room S as shown in FIG. Here, if there is an instruction input for powerful operation, the air heat-exchanged by the indoor heat exchanger 11 in the direction in which the person is present, as shown in FIG. 8 (b), according to the detection result from the infrared sensor 44. The flap motor 146 is controlled so as to blow out, and the direction of the horizontal flap 144 is adjusted.

  As a result, even if the horizontal flap 144 is directed in any direction before the powerful operation instruction is input, the horizontal flap 144 is always oriented in the direction in which the person is present when the powerful operation instruction is input. Controlled to change. Therefore, the user can feel a powerful feeling by powerful operation by receiving directly air-conditioned air by inputting a command for powerful operation.

Such a powerful operation is performed in the same way during the heating operation.
The powerful operation temporarily enhances the air conditioning processing capability of the air conditioner 1, and the time for performing the powerful operation is limited by the timer 45. The timer 45 starts measuring time after the control unit 60 receives a powerful driving instruction input from the user, and transmits a signal to the control unit 60 when a predetermined time comes. When receiving the signal from the timer 45, the control unit 60 controls the fan motor 13, the compressor 21, and the flap motor 146 so as to return to the original normal operation state, ends the powerful operation, and returns to the normal operation state.

In the air conditioner 1 according to the present embodiment, the timer 45 is input with a set time so that no condensation occurs near the air outlet 143 even when air is directly blown out near the air outlet 143 during cooling powerful operation. Yes.
Thus, the problem that condensation occurs near the blowout port 143 can be reliably prevented by providing a time limit, regardless of the direction in which the horizontal flap 144 is directed during the cooling powerful operation.
[Features of this air conditioner]
(1)
The air conditioner 1 of this embodiment, when an instruction input for performing a powerful operation is received from the remote controller 40, temporarily increases the rotational speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like to increase the air conditioning processing capability. While improving, it controls to the wind direction.

  Even in a conventional air conditioner, when such an instruction input that temporarily increases the processing capacity is input, the rotational speed of the fan, the operating frequency of the compressor, and the like have been increased. However, at this time, the direction of the air supplied into the room was not controlled, so the direction of the wind was determined by the direction of the direction of the horizontal flap immediately before the input of the powerful operation instruction.

Therefore, in the air conditioner 1 of the present embodiment, the air that has been conditioned in the state in which the driving ability is increased is controlled by controlling the direction of the horizontal flap 144 even during so-called powerful operation, which temporarily increases the processing ability. It can be blown out in a desired direction.
In particular, in the air conditioner 1 of this embodiment, the direction of the horizontal flap 144 is controlled so as to blow out air that has been air-conditioned toward the direction of a person in the room.

As a result, when the powerful operation is set by the user, air that is air-conditioned blows out toward the user, so that the user can feel a powerful feeling during the powerful operation.
(2)
The air conditioner 1 of the present embodiment senses the direction in which a person is present in the room using the infrared sensor 44.

Thereby, the direction of the horizontal flap 144 can be adjusted so that the wind directly hits the person regardless of the position of the person in the room.
(3)
In the air conditioner 1 of the present embodiment, when a powerful operation instruction is input, the direction of the horizontal flap 144 is fixed and air conditioned in the direction in which a person is present is blown out.

Thereby, it is possible to make the user in the room feel a powerful feeling during the powerful driving.
(4)
The air conditioner 1 of the present embodiment uses the timer 45 to limit the time for performing powerful operation.

This makes it possible to control the powerful operation as temporarily increasing the air conditioning processing capacity.
(5)
In the air conditioner 1 of the present embodiment, the set time of the timer 45 is set to a time that does not cause condensation near the outlet 143 of the indoor unit 2.

Normally, in a powerful operation during cooling, if the horizontal flap 144 is directed in the direction in which a person is present, air conditioned air may hit the vicinity of the outlet. In such a case, if cold air is continuously blown out for a long time, condensation may occur in the vicinity of the blowout port.
Therefore, in the air conditioner 1 of this embodiment, it is possible to reliably prevent condensation near the blowout port 143 by limiting the time during which the horizontal flap 144 is directed.

(6)
The air conditioner 1 of this embodiment controls the blowing direction of the air supplied indoors using the horizontal flap 144. FIG.
Thereby, compared with the case where the direction of a vertical flap is controlled, by performing control using the horizontal flap 144 which adjusts the wind direction of an up-down direction, air can be easily blown out in the direction where a person exists.
[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the above-described embodiment, an example has been described in which the infrared sensor 44 is used to sense the direction in which a person is present and air that is conditioned in air during powerful driving is blown in that direction. However, the present invention is not limited to this. For example, air conditioned air may be blown out toward a specific range assumed to be a person's place without using a sensor.

In addition, the sensor is not limited to the infrared sensor as long as it can sense a person's whereabouts, and other sensors may be used.
(B)
In the above embodiment, the example in which the direction of the horizontal flap 144 is fixed in the direction in which the person is present during the powerful operation has been described. However, the present invention is not limited to this. For example, as shown in FIG. 9 (a), during normal cooling operation, when the horizontal flap 144 swings between a substantially horizontal direction and a downward direction of several degrees from the horizontal direction, As shown in FIG. 9B, the horizontal flap 144 may be swung by extending the swing range so as to include the direction in which the person is present. Even in this case, since the user can directly feel the air blown out during the powerful operation, the user can feel a powerful feeling as in the case where the horizontal flap 144 is fixed so as to face the direction in which the person is present. .

(C)
In the above-described embodiment, an example has been described in which the direction of the horizontal flap 144 is controlled to blow air that has been air-conditioned into a room in the up and down direction in a powerful operation. However, the present invention is not limited to this. For example, the wind direction may be controlled in the left-right direction using a vertical flap, or the wind direction may be controlled using both a vertical flap and a horizontal flap 144.

(D)
In the above embodiment, when an instruction is input to perform a powerful operation regardless of cooling or heating, the direction of the horizontal flap 144 is controlled so as to blow out air conditioned in the direction of being in a person. And explained. However, the present invention is not limited to this. For example, the control of the direction of the horizontal flap 144 may be limited so that air conditioned in the direction in which the person is present is blown out only when an instruction for powerful operation is input during cooling.

Thereby, it is possible to make the user feel the cooling feeling in the powerful operation at the time of cooling and to realize the powerful feeling in the more powerful operation.
(E)
Further, in the above embodiment, the example in which the time for performing the powerful operation is limited by the timer 45 has been described. However, the present invention is not limited to this. For example, the timer 45 may be set to a time for fixing the direction of the horizontal flap 144 during the powerful operation. In this case, the horizontal flap 144 that is fixed at a predetermined angle during the powerful operation may be controlled to swing after the time limit set in the timer 45 has elapsed.

  The present invention can be applied to an air conditioner capable of performing a powerful operation during a cooling operation and a heating operation because the air blowing direction that is air-conditioned during the powerful operation can be controlled.
