  Hereinafter, control performed by the air conditioner will be described with reference to the flowcharts of FIGS. 3A and 3B. In addition, the said control is started according to operation of a remote control, for example.

  When the above control is started, as shown in FIG. 3A, first, in step S1, the window temperature is determined based on the indoor surface temperature of the window W detected by the temperature sensor 2 and the indoor humidity detected by the humidity sensor 4. It is determined whether or not condensation occurs on the indoor surface of W. If it is determined in step S1 that no condensation occurs on the indoor surface of the window W, step S1 is performed again. On the other hand, if it is determined in step S1 that condensation occurs on the indoor surface of the window W, the process proceeds to step S2.

  Next, in step S2, the indoor unit 1 is caused to start the air blowing operation. As a result, air having substantially the same temperature as the room temperature blows out from the indoor unit 1 into the room.

  Next, in step S3, it is determined using the human sensor 5 whether or not there is a person in the room. If it is determined in step S3 that there is a person in the room, the control proceeds to step S4 after the control in step S4. On the other hand, if it is determined in step S3 that there is no person in the room, the process proceeds to step S5 after performing the control in step S11.

  In the above step S4, the vertical blades of the wind direction adjusting unit 3 are kept constant so that the air blown out from the indoor unit 1 into the room intermittently hits the window W based on the data indicating the position of the window W stored in the nonvolatile memory. Swing left and right at speed. In step S4, the horizontal blade may not swing.

  In the step S11, the wind direction adjusting unit 3 is controlled based on the data indicating the position of the window W stored in the non-volatile memory so that the air blown into the room from the indoor unit 1 continuously hits the window W. That is, based on the data indicating the position of the window W stored in the non-volatile memory, the wind direction adjustment is performed so that the air blown from the indoor unit 1 into the room is directed toward the window W and the wind direction adjusting unit 3 does not swing. Part 3 is controlled.

  Next, as shown in FIG. 3B, in step S5, it is determined whether or not a preset time has elapsed since the start of the air blowing operation. If it is determined in step S5 that the preset time has not elapsed, step S5 is performed again. On the other hand, if it is determined in step S5 that a preset time has elapsed, the process proceeds to step S6.

  Next, in step S6, the indoor unit 1 is allowed to start the heating operation. Thereby, the air whose temperature has increased in the indoor heat exchanger 11 blows out from the indoor unit 1 into the room.

  Finally, whether or not condensation occurs on the indoor surface of the window W based on the indoor surface temperature of the window W detected by the temperature sensor 2 and the indoor humidity detected by the humidity sensor 4 in step S7. Determine whether or not. If it is determined in step S7 that condensation occurs on the indoor surface of the window W, step S7 is performed again. On the other hand, when it is determined in step S7 that no condensation occurs on the indoor surface of the window W, the above control is ended. Along with this, heating operation and the like are stopped.

  Here, step 1 is an example of a determination unit, and steps S2, S4, S6, and S11 are examples of a control unit.

  As described above, when it is determined in step S <b> 1 that condensation occurs on the indoor surface of the window W, the indoor unit 1 and the airflow direction adjusting unit 3 are set so that the indoor unit 1 blows air toward the window W. Control. Thereby, when the dew condensation has generate | occur | produced on the indoor side surface of the said window W, the air from the indoor unit 1 can be applied to the indoor side surface of the window W, and a dew condensation can be dried. Therefore, deterioration of the dew condensation can be effectively prevented.

  Further, since the temperature sensor 2 is attached to the window W, the surface temperature of the window W on the indoor side can be accurately detected. Thereby, before the dew condensation on the indoor side surface of the window W becomes severe, the air from the indoor unit 1 can be applied to the indoor side surface of the window W. Therefore, the deterioration of the dew condensation can be prevented more effectively.

  Moreover, since the air from the indoor unit 1 can be applied to the indoor surface of the window W to dry the condensation, the time for preventing the condensation from deteriorating can be shortened.

  Moreover, when it determines with dew condensation having generate | occur | produced on the surface of the indoor side of the window W by said step S1, the indoor unit 1 carries out heating operation after carrying out ventilation operation for the preset time. Therefore, the dew condensation that takes time to dry only by the air blowing operation can be dried in a short time.

  Further, when it is determined in step S3 that there is no person in the room, the air blown out from the indoor unit 1 into the room is continuously directed toward the window W. Therefore, the condensation on the indoor side surface of the window W can be efficiently dried. In other words, it is possible to concentrate on dealing with condensation without worrying about the comfort in the room.

  Further, when it is determined in step S3 that there is a person in the room, the wind direction adjusting unit 3 swings. Therefore, the temperature unevenness in the room can be reduced. As a result, the indoor comfort can be improved.

  Even if the wind direction adjusting unit 3 swings, the air blown out from the indoor unit 1 into the room intermittently hits the window W, so that the condensation on the surface on the indoor side of the window W can be dried.

  Moreover, since the said recognition part 6 recognizes the position of the window W based on the information which a user inputs, the reliability of recognition of the position of the window W can be improved.

  In the above-described embodiment, when it is determined that condensation occurs on the indoor side surface of the window W, the indoor unit 1 is in the heating operation after the air blowing operation for a preset time. You may just make it.

  In the above embodiment, the vertical blades of the wind direction adjusting unit 3 are swung left and right at a constant speed, but the vertical vanes of the wind direction adjusting unit 3 may be swung left and right at a non-constant speed.

  For example, the swing speed of the vertical blades of the wind direction adjusting unit 3 when the air blowing from the indoor unit 1 toward the room is directed to the window W is the wind direction adjusting unit 3 when the air blowing from the indoor unit 1 to the room is other than the window W. The swing speed of the vertical blades may be slower.

  In other words, when the swing speed of the vertical blades of the wind direction adjusting unit 3 is relatively slow, the air blown from the indoor unit 1 into the room is directed to the window W, while the vertical blades of the wind direction adjusting unit 3 When the swing speed is relatively fast, the air blown into the room from the indoor unit 1 may be directed to a place other than the window W.

  That is, while the vertical blades of the wind direction adjusting unit 3 swing at a relatively slow speed from the rotation angle corresponding to the position of the window W to the swing by a preset rotation angle, After swinging by a preset rotation angle from the rotation angle corresponding to the position, the vertical blades of the wind direction adjusting unit 3 may swing at a relatively high speed.

  As described above, the vertical blades of the wind direction adjusting unit 3 are swung left and right at a non-constant speed, so that the air applied to the indoor surface of the window W while the vertical blades of the wind direction adjusting unit 3 swings once. Can be increased. Therefore, even if the vertical blades of the wind direction adjusting unit 3 are swung, it is possible to prevent the efficiency of drying the condensation on the indoor surface of the window W from greatly decreasing.

  Moreover, since the vertical blade | wing of the said wind direction adjustment part 3 swings, indoor temperature irregularity can be reduced. Therefore, indoor comfort can be improved.

  In the above embodiment, the recognition unit 6 recognizes the position of the window W based on information input by the user, but recognizes the position of the window W based on a signal from the temperature sensor 2. May be. In this way, the recognition unit 6 can automatically recognize the position of the window W.

  In the above embodiment, the air conditioner performs control corresponding to the flowcharts of FIGS. 3A and 3B, but may perform control corresponding to the flowcharts of FIGS. 4A and 4B.

  When the above control is started, as shown in FIG. 4A, first, in step S21, based on the indoor surface temperature of the window W detected by the temperature sensor 2 and the indoor humidity detected by the humidity sensor 4, the window It is determined whether or not condensation occurs on the indoor surface of W. If it is determined in step S21 that no condensation occurs on the indoor surface of the window W, step S21 is performed again. On the other hand, if it is determined in step S21 that condensation occurs on the indoor surface of the window W, the process proceeds to step S22.

  Next, in step S22, the indoor unit 1 is caused to start the air blowing operation. As a result, air having substantially the same temperature as the room temperature blows out from the indoor unit 1 into the room.

  Next, in step S23, based on the data indicating the position of the window W stored in the nonvolatile memory, the vertical blades of the wind direction adjusting unit 3 so that the air blown out from the indoor unit 1 into the room intermittently hits the window W. Swing left and right at a constant speed. In step S23, the horizontal blade may not swing.

  More specifically, the swing speed of the vertical blades of the wind direction adjusting unit 3 when the air blown into the room from the indoor unit 1 is directed to the window W is adjusted for the wind direction when the air blown from the indoor unit 1 to the room is directed to other than the window W. The vertical blades of the wind direction adjusting unit 3 are controlled so as to be slower than the swing speed of the vertical blades of the unit 3.

  In other words, when the swing speed of the vertical blades of the wind direction adjusting unit 3 is relatively slow, the air blown out from the indoor unit 1 toward the room is directed to the window W, while the vertical blades of the wind direction adjusting unit 3 are swung. When the speed is relatively fast, the vertical blades of the wind direction adjusting unit 3 are controlled so that the air blown out from the indoor unit 1 into the room is directed to other than the window W.

  That is, while the vertical blades of the wind direction adjusting unit 3 swing at a relatively slow speed from the rotation angle corresponding to the position of the window W to the swing by a preset rotation angle, After swinging by a preset rotation angle from the rotation angle corresponding to the position, the vertical blades of the wind direction adjusting unit 3 are controlled so that the vertical blades of the wind direction adjusting unit 3 swing at a relatively high speed. .

  Next, in step S24, it is determined whether a preset time has elapsed since the start of the air blowing operation. If it is determined in step S24 that the preset time has not elapsed, step S24 is performed again. On the other hand, if it is determined in step S24 that a preset time has elapsed, the process proceeds to step S25.

  Next, as shown in FIG. 4B, in step S25, the indoor unit 1 is allowed to start the heating operation. Thereby, the air whose temperature has increased in the indoor heat exchanger 11 blows out from the indoor unit 1 into the room.

  Finally, whether or not condensation occurs on the indoor surface of the window W based on the indoor surface temperature of the window W detected by the temperature sensor 2 and the indoor humidity detected by the humidity sensor 4 in step S26. Determine whether or not. If it is determined in step S26 that condensation occurs on the indoor surface of the window W, step S26 is performed again. On the other hand, when it is determined in step S26 that no condensation occurs on the indoor surface of the window W, the above control is ended. Along with this, heating operation and the like are stopped.

  Here, step 21 is an example of a determination unit, and steps S22, S23, and S25 are examples of a control unit.

  As described above, the vertical blades of the wind direction adjusting unit 3 are swung left and right at a non-constant speed, so that the air applied to the indoor surface of the window W while the vertical blades of the wind direction adjusting unit 3 swings once. Can be increased. Therefore, even if the vertical blades of the wind direction adjusting unit 3 are swung, it is possible to prevent the efficiency of drying the condensation on the indoor surface of the window W from greatly decreasing.

  Moreover, since the vertical blade | wing of the said wind direction adjustment part 3 swings, indoor temperature irregularity can be reduced. Therefore, indoor comfort can be improved.

  Moreover, the said air conditioner does not need to be provided with the human detection sensor 5 when performing the control corresponding to the flowchart of FIG. 4A and FIG. 4B.
