In step S10, control unit 310 accepts a call operation for a draft feeling prevention side blowing position wind direction angle setting screen on user setting screen 10A shown in FIG. In step S11, the control unit 310 accepts an input operation of the address of the air conditioner to be set on the draft feeling prevention side blowing position wind direction angle setting screen 11A shown in FIG. The air conditioner for which the address is input on the draft feeling prevention side blowing position wind direction angle setting screen 11A is a setting target of the wind direction angle of the side blowing position V1. The air conditioner that is the setting target of the wind direction angle of the side blowing position V1 is notified from the control unit 310 that it is the setting target of the wind direction angle of the side blowing position V1. In step S12, the control unit 120 of the indoor unit 10 designated as the target for setting the wind direction angle of the side blowing position V1 moves the vertical wind direction vane 14 from the closed state to the side blowing position V1 at the current setting, The user can recognize which air conditioner is the target of setting the wind direction angle of the blowing position V1.

FIG. 9 is a diagram illustrating the movement of the up and down air direction vanes when the air direction angle of the side blowing position V1 of the air conditioner according to Embodiment 1 is adjusted. When the user presses the up button, an up operation is performed in step S13. In step S14, the control unit 120 causes the vane motor 15 to output a pulse from the vane motor driving circuit 140 so that the up-and-down wind direction vane 14 is directed upward. As shown by an arrow A in FIG. 9, the side blowing position V1 changes to a position above the current position.

In step S21, control unit 310 accepts an input operation of the address of the air conditioner to be set on lower blow position wind direction angle setting screen 21A shown in FIG. The air conditioner whose address is input on the lower blowing position wind direction angle setting screen 21A is a setting target of the wind direction angle of the fourth lower blowing position V5. The air conditioner that is the target of setting the wind direction angle of the fourth lower blowing position V5 is notified from the control unit 310 that it is the target of setting the wind direction angle of the fourth lower blowing position V5. In step S22, the control unit 120 of the indoor unit 10 designated as the target for setting the airflow direction angle of the fourth lower blowing position V5 starts from the closed state of the up / down airflow vane 14 and changes to the fourth lower blowing position at the current setting. It moves to V5 so that the user can recognize which air conditioner is the target of setting the wind direction angle of the fourth bottom blowing position V5.

In step S23, the control unit 310 determines whether or not an operation for adjusting the wind direction angle of the fourth lower blowing position V5 of the upper and lower wind direction vanes 14 is received on the lower blowing position wind direction angle setting screen 13A shown in FIG. When the user presses the up button, the up operation is performed in step S23, and in step S24, a pulse is output from the vane motor drive circuit 140 to the vane motor 15 so that the up-and-down wind direction vane 14 faces upward, and the fourth down-blow is performed. The position V5 changes to a position above the current position. When the user presses the down button, a down operation is performed in step S23, and in step S25, a pulse is output from the vane motor driving circuit 140 to the vane motor 15 so that the up-and-down airflow vane 14 is directed downward, and the fourth bottom blow is performed. The position V5 changes to a position below the current position. In step S26, the control unit 310 determines whether or not a confirming operation has been performed on the lower blowing position wind direction angle setting screen 22A shown in FIG. 12, and if the confirming operation has not been performed, the control unit 310 returns to step S23 and returns to the up and down wind direction vane 14. An adjustment operation of the wind direction angle of the fourth lower blowing position V5 is accepted. When the confirmation operation is performed, in step S27, the pulse data of the vane motor 15 at the fourth lower blowing position V5 after the setting change is calculated based on the number of pulse steps from the fourth lower blowing position V5 in the initial state. Then, the data is stored in the storage unit 130 of the indoor control board 110, and the vane position data of the fourth bottom blowing position V5 is updated. In step S28, the control unit 120 closes the up / down airflow direction vane 14 of the indoor unit 10 and ends the setting change.

FIG. 13 is a conceptual diagram of the memory data update of the indoor control board of the air conditioner according to the third embodiment. The data of the fourth bottom blowing position V5 of the up and down wind direction vane 14 is updated from S1000 to S1200. In this case, when the fourth lower blowing position V5 is set through the remote controller 30, the control unit 120 drives the vane motor 15 for 1200 steps to rotate the up-and-down wind direction vane 14.

As described above, the air conditioner according to Embodiment 3 can adjust the lower blowing direction angle to an angle other than the product-defined angle by an operation through the remote controller 30. Therefore, even when the region where the wind does not reach becomes wider at the product-defined angle, by adjusting the wind direction angle, the range where the wind reaches can be expanded and the comfort can be improved.
