The control unit according to the present invention is to control the air flow and the air direction of the air discharged from the discharge port according to the elapse of the sleep operation time, the sleep operation mode and the sleep operation time input by the user, more specifically, It is characterized by adjusting the angle of the discharge blade installed in the discharge port in order to control the air flow and the direction of the air discharged from the discharge port by dividing into the elevation, the continuous sleep during the sleep operation, and the weather at the end of the sleep operation.

     Hereinafter, the operation process and the effect of the wind direction control method during the sleep operation of the air conditioner configured as described above will be described.

     4 is an operation flowchart of a wind direction control method for a sound sleep operation during the sleep operation of the air conditioner according to the present invention. First, direct air is defined as direct air, which is heat-exchanged with an indoor heat exchanger, and is discharged so that the air discharged from the discharge port is directed directly to the user's body, and indirect wind is defined as being discharged so that the discharged air is not directly directed to the user's body. Intermittent wind is defined as intermittent air that is provided to the user's body intermittently, that is, repeatedly provided at predetermined time intervals between the direct wind and the indirect wind. Hereinafter, the cooling operation will be described as an example.

     When the operation switch is turned on by the user to operate the air conditioner for cooling the room, the ON signal applied through the operation switch is supplied to the control unit 140 through the power supply unit 100. When input, the controller 140 applies an operation signal to the compressor driver 150 to operate the compressor 20 to perform normal cooling operation of the air conditioner (S100).

      When the compressor 20 is started by the operation S100, the refrigerant generated from the compressor 35 is circulated between the indoor heat exchanger 11 and the outdoor heat exchanger 24, thereby performing heat exchange. Cooling of the room is achieved while the air is discharged to the room side. In addition, the controller 140 controls the indoor fan driver 160 and the indoor fan driver 170 to control the indoor fan 12 and the outdoor fan 25 to operate.

     In this state in which the normal cooling operation is performed, the control unit 140 determines whether the sleep operation is set according to the user control command from the signal input unit 110 (S110), and if the sleep operation is not set as a result of the determination, the control unit continues. To perform normal operation.

     When the sleep operation is set as a result of the determination in step S110, while performing the sleep operation, the controller 140 determines whether the sleep operation time is input by the user from the signal input unit 110 (S120a), and the determination result is the sleep operation time. In this case, the charging operation time set by the user is counted by a timer (S140). In addition, when the sleep operation time is not input (S120b), the sleep operation time predetermined by the system is counted by a timer (S140).

    The sleep operation and the sleep operation time of steps S110 to 140 are set, and during the elevation of the sleep operation in which the timer starts counting the sleep operation time, the control unit may provide an intermittent wind for a predetermined time to induce sleep. 140 applies an operation signal to the front discharge blade driving unit 180 to drive a third step motor (not shown) to swing the front discharge blade 17 in the vertical direction. In addition, an operation signal is applied to the side discharge blade driving unit 190 to drive the first and second step motors 18a and 18b to swing the left discharge blade 16b and the right discharge blade 16a in the left and right directions. (S150)

    As such, when the user who is in the early stage of sleep operation starts to fall asleep, the discharge blade swings for a predetermined time, so that the air discharged from the discharge port gives the user a rhythmic air flow, and falls asleep quickly in a more comfortable sleep environment. To guide them.

     When the swing of the discharge blade according to step S150 has elapsed for a predetermined time, the controller 140 compares the sleep operation time counted by the timer with the first set time t1 set by the user, and the sleep operation time is the first set time. It is determined whether (t1) has passed. (S160)

     If the elapsed time of the bedtime operation has passed the first predetermined time t1 in step S160, the controller 140 applies an operation signal to the front discharge blade driving unit 180 to provide indirect wind to the user to induce a good night's sleep. The driving of the three-step motor (not shown) is stopped to fix the front discharge blade 17. In addition, an operation signal is applied to the side discharge blade driving unit 190 to stop driving of the first step motor 18a and the second step motor 18b to fix the left discharge blade 16b and the right discharge blade 16a. (S180)

     At this time, the discharge blade is fixed in the front discharge blade 17 is fixed in a horizontal direction or upward so that cold air is not directly transmitted to the user. That is, the air discharged from the front discharge port 15 is fixed to the horizontal direction or the ceiling surface. In addition, the direction in which the left discharge blade 16a and the right discharge blade 16b are fixed is fixed to face the direction perpendicular to the side of the main body 10 or the rear surface of the main body. That is, the air discharged from the side discharge ports 14a and 14b is fixed to the side direction or to the rear side where the indoor unit main body 10 is installed.

       If the bedtime operation time has not passed the first set time t1 in step S160, the controller 140 controls the room temperature Tr sensed by the room temperature sensing unit 120 and the set temperature Ts set by the user. Compared to (S170), when the room temperature (Tr) is lower than the set temperature (Ts), because excessive cold air is delivered to the user may prevent the user from entering a deep sleep, in this case, the bedtime operation is the first setting Even if the time t1 has not elapsed, the swings of the respective discharge blades 17, 16a, and 16b are fixed. However, when the room temperature is higher than the set temperature, each of the discharge blades 17, 16a, 16b is continuously swinged.

     Here, the first set time (t1) is set by the user, but if not set by the user, the preset time is about 30 minutes, which is the time that the user normally falls into deep sleep by experiment. It is also possible to judge by.

     In the state in which indirect wind is provided to the user while continuing to sleep in step S180, the controller 140 compares the sleep operation time counted by the timer with the second set time t2 set by the user (S190). When the remaining time is less than or equal to the second predetermined time t2, the controller 140 applies an operation signal to the discharge blade driving units 170 and 180 to discharge each of the discharges in order to induce the weather by providing the user with intermittent wind during the weather. Swing the blades (17, 16a, 16b) (S200).

     In this way, each discharge blade (17, 16a, 16b) is swinging during the wake-up, so the user can wake up more easily and comfortably because of the rhythmic air flow to the user.

      At the same time that the sleep operation is counted and the sleep operation time counted is completed, the controller 140 ends the sleep operation.

       In addition, when the discharge blade is swinged to provide an intermittent wind to the user in steps S150 and S200, the angle at which the discharge blade is positioned during swinging of the discharge blade is directly used to reduce the time for direct delivery of cold air to the user. The length of time for indirect winds is longer than for winds.

     What has been described above is just one embodiment for implementing the wind direction control method for the sound sleep operation during the sleep operation of the air conditioner according to the present invention, the present invention is not limited to the above-described embodiment, the technical features of the present invention It is obvious that various modifications are possible by one of ordinary skill in the art within the spirit.

     For example, although the present invention has been described as being limited to a stand type air conditioner, it is of course applied to a wall-mounted air conditioner and a ceiling type air conditioner.

    As described in detail above, the airflow control method in the sleep operation of the air conditioner according to the present invention is the air flow and the wind direction of the air discharged in consideration of not only during sleep, but also during the initial sleep and the end of the bedtime weather By providing differently, the user can be provided with an environment in which a user can sleep more comfortably and comfortably.

     In other words, by providing the user with intermittent wind at the time of elevation, it is possible to relieve the muggy for use in the tropical nights in summer, and also to give the user a rhythmic air flow to the user's body to induce a deeper sleep faster. There is.

     In addition, by providing an intermittent wind to the user even during the weather there is an effect that allows the user to wake up more easily and comfortably by giving a rhythmic air flow to the human body.

      In addition, since the air flow is not directly transmitted to the user's human body by providing indirect wind to the user during sleep, there is an effect of preventing the human body from being disturbed by supercooling.
