- the air conditioner 1 of the first embodiment uses the horizontal flap 144 to control the direction in which the air supplied to the room is blown out.
- air-conditioned air may be blown out to a specific range that is assumed to be a person's location without using a sensor.
- the senor is not limited to the infrared sensor as long as it can detect the location of a person, and another sensor may be used.
- the direction of the horizontal flap 144 is fixed in a direction where a person is present during the powerful operation.
- the present invention is not limited to this.
- the horizontal flap 144 may be swung by extending the swing range to include the direction where the person is. Even in this case, since the user can directly feel the air blown out during the powerful operation, it is possible to make the user feel a powerful feeling similarly to the case where the horizontal flap 144 is fixed so as to face the direction where the person is. it can.
- the direction of the horizontal flap 144 is controlled and the air-conditioned air is blown into the room during the powerful operation in the vertical direction in which a person is present.
- the present invention is not limited to this.
- the wind direction may be controlled in the left-right direction using the vertical flap, or the wind direction may be controlled using both the vertical flap and the horizontal flap 144.
- the direction of the horizontal flap 144 is controlled so as to blow out the air-conditioned air in the direction of the person.
- the example has been described.
- the present invention is not limited to this.
- the control of the direction of the horizontal flap 144 may be limited so that the air-conditioned air is blown out in the direction in which a person is present only when a powerful driving instruction is input during cooling.
- the time during which the powerful operation is performed is limited by the timer 45.
- the present invention is not limited to this.
- a time for fixing the direction of the horizontal flap 144 during the powerful operation may be set in the timer 45.
- the horizontal flap 144 fixed at a predetermined angle during the powerful operation is controlled to swing after the time limit set in the timer 45 elapses.
- control unit 60 controls the flap motor 146 so as to blow out the air subjected to the heat exchange processing (air conditioning) by the indoor heat exchanger 11 in a direction where no one is present. It differs from the air conditioner according to the first embodiment in that the direction of 144 is adjusted. Therefore, only the operation of the air conditioner during the powerful operation is described here.
- the control unit 60 of the air conditioner 1 increases the rotation speed of the cross flow fan 12 to improve the air conditioning processing capacity.
- the operating frequency of the compressor 21 is controlled.
- the control unit 60 controls the direction of the horizontal flap 144 by performing the control described in the first embodiment. For example, it is assumed that, during the cooling operation, air whose air is conditioned in a substantially horizontal direction with a slightly downward airflow is blown into the room S as shown in FIG.
- the indoor heat exchanger 11 performs heat exchange processing (in the direction where no one is present) according to the detection result from the infrared sensor 44, as shown in FIG. 10 (b).
- Air conditioning Controls the flap motor 146 to blow out the air that has been adjust.
- the direction of the horizontal flap 144 during the operation before the instruction input of the full driving is inputted and even if the instruction of the powerful driving is input, the direction in which no person is present is always present.
- the horizontal flap 144 is controlled so as to change its direction. Therefore, even if the occupant inputs a command for a full operation, the occupant can comfortably stay in the room without feeling excessive cooling feeling due to direct wind blow during cooling.
- the powerful operation temporarily increases the air conditioning processing capacity of the air conditioner 1, and the time during which the powerful operation is performed is limited by the timer 45.
- the timer 45 receives the powerful operation instruction input from the user by the control unit 60 and starts measuring the time of the force, and sends a signal to the control unit 60 when a predetermined time comes.
- the control unit 60 controls the fan motor 13, the compressor 21, and the flap motor 146 to return to the original normal operation state, terminate the powerful operation, and return to the normal operation state .
- the air conditioner 1 When an instruction to perform a powerful operation is input from the remote controller 40, the air conditioner 1 according to the second embodiment temporarily increases the rotation speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like, thereby controlling the air conditioner. The processing capacity is improved and the wind direction is controlled.
- the processing capacity is temporarily increased, that is, the direction of the horizontal flap 144 is controlled even during the so-called full operation, so that the air conditioning is performed with the operation ability improved. Air can be blown out in a desired direction.
- the direction of the horizontal flap 144 is controlled so as to blow out the air-conditioned air while avoiding the direction where the person is.
- the air-conditioned air is blown out in a direction other than the direction where the person is present, for example, near the ceiling. Therefore, for example, even if a powerful operation is installed during cooling, it is possible to prevent direct cold air from directly hitting a person, and thus it is possible to perform a powerful operation without giving discomfort due to excessive cooling sensation .
- the air conditioner 1 of the second embodiment uses an infrared sensor 44 to detect the direction in which a person is indoors.
- the direction of the horizontal flap 144 can be adjusted so that the wind does not directly hit the person regardless of the position of the person in the room.
- the direction of the horizontal flap 144 is fixed, and air that is air-conditioned in a direction where no one is present is blown out.
- air that is air-conditioned in a direction where no one is present is blown out.
- the time during which the powerful operation is performed is limited by using a timer 45 that operates inside the program.
- the air conditioner 1 uses the horizontal flap 144 to control the blowing direction of the air supplied to the room.
- the direction of the horizontal flap 144 is fixed in a direction where no one is present during the powerful operation.
- the present invention is not limited to this.
- the horizontal flap 144 when the horizontal flap 144 is swinging downward from the horizontal direction by several degrees during the cooling operation, as shown in Fig.
- the horizontal flap 144 may be swung within a range not including the direction in which the person is. Even in this case, the user does not directly hit the air blown out during the powerful operation, so that the user does not feel discomfort as in the case where the horizontal flap 144 is fixed so that the person is present and facing the direction. Powerful operation can be performed.
- the direction of the horizontal flap 144 is controlled and the air-conditioned air is blown into the room during the powerful operation in the vertical direction where no one is present.
- the invention is not so limited.
- the wind direction may be controlled in the left-right direction using a vertical flap or both the horizontal flap 144 and the vertical flap.
- the direction of the horizontal flap 144 is controlled so as to blow air-conditioned air in a direction where no one is present.
- the example has been described.
- the present invention is not limited to this.
- the control of the direction of the horizontal flap 144 may be limited so that the air-conditioned air is blown out in a direction where no one is present only when a powerful operation instruction is input during cooling.
- the present invention has an effect that the blowing direction of air-conditioned air can be controlled during a powerful operation, so that the present invention can be applied to an air conditioner that can perform a powerful operation during a cooling operation and a heating operation. .
