[0008]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described in detail with reference to FIG. 2 and 3
In this embodiment, the air conditioner of this embodiment includes a control circuit (microcomputer) 1 on the indoor unit side and an outdoor unit control device 2, and performs control necessary for controlling the room temperature.

The indoor unit has opening and closing panel portions 3a, 3 comprising a front panel and an upper panel to form an air intake port.
b, a short circuit panel portion 3c provided at a lower portion of the front panel 3a for forming a suction port for sucking the blown air, a vertical wind direction plate portion 4 for changing an air blowing direction, and a room. Heat exchanger 5a, 5
b, 5c, an indoor fan unit 6, an electric dust collecting unit 7 arranged behind the front panel, and a remote controller 8 capable of setting internal clean operation. The opening / closing panel 3
a, 3b, the short circuit panel portion 3c, the vertical wind direction plate portion, and the indoor fan portion 6 each include a motor and the like.

The control circuit 1 controls the open / close panel sections 3a, 3b, the short circuit panel section 3c, the vertical wind direction panel section 4, the indoor fan section 6, and the electric dust collection section 7 in accordance with the setting operation of the remote controller 8. The operating frequency code of the compressor according to the difference between the room temperature and the set temperature is transmitted to the outdoor unit controller 6 and a signal necessary for the room temperature control is exchanged with the outdoor unit controller 2.

The control circuit 1 includes a determination section 1a for determining a signal from the remote controller 8, and a timer section 1b used in a routine described later. The air conditioner further includes a refrigeration cycle portion necessary for controlling the room temperature, various sensors, a drain pan 9, and the like.

Next, the operation of the air conditioner configured as described above will be described with reference to the flowchart of FIG. First, when a setting operation of the remote controller 8 is performed, control necessary for the room temperature control is performed by the indoor unit-side control circuit 1 and the outdoor unit control device 2 according to the setting operation. In this case, the control circuit 1 automatically controls the opening and closing of the open / close panel sections 3a and 3b according to the operation mode of the setting operation and the like, and also controls the electric dust collecting section 7. The short circuit panel 3c is normally closed.

When the clean button of the remote controller 8 is pressed during the operation of the air conditioner described above or during the stop of the operation, and the setting operation of the internal clean operation is performed by the remote controller 8, the control circuit 1 shown in FIG. Execute the routine. In this routine, the indoor fan 6
Is stopped, and the open / close panel sections 3a and 3b are closed (step ST1).

Subsequently, the upper and lower wind direction plate portions 4 are set to the upper outlet (step ST2), and the short circuit panel portion 3c is opened downward (step ST3) to form an air inlet. For this reason, the air blown upward by the rotation of the indoor fan unit 6 described later is immediately drawn into the indoor unit from the air suction port.

Subsequently, a 20-minute timer is started by the timer unit 1b (step ST4), and the electric dust collecting unit 7 is turned on (step ST5). Therefore, ozone is diffused into the indoor unit by energization of the electric dust collecting unit. A predetermined time (for example, 1
Minute) is masked (step ST6). That is, it waits for 30 seconds, and when this 30 seconds has elapsed, controls the indoor fan unit 6 at a predetermined rotation speed (for example, 600 rpm) (step ST7). Thereby, the ozone is circulated inside the indoor unit without being diffused into the room.

Subsequently, masking is performed for a predetermined time (for example, 5 seconds) (step ST8), and when 5 seconds have elapsed, the indoor fan unit 6 is stopped (step ST9). This is because if the rotation of the indoor fan unit 6 is controlled for about 5 seconds, ozone will be sufficiently distributed inside the indoor unit.

Subsequently, it is determined that the 20-minute timer has expired (step ST10). If the time has not expired, the process returns to step ST6 to repeat the above-described processing.
Therefore, for 20 minutes, the indoor fan 6
The rotation is controlled at 600 rpm per second. That is, since the indoor fan unit 6 is intermittently controlled, ozone does not diffuse into the room and sufficiently circulates inside the indoor unit.
Deodorization and sterilization inside the indoor unit are effectively performed.

Subsequently, the electric dust collecting section 7 is turned off (step ST11), the short circuit panel section 3c is closed, and the vertical wind direction plate section 4 is closed (step ST12). If the air conditioner is operating, the operation returns to the original operation. That is, control according to the setting operation of the remote controller 8 is performed as described above.

In the above embodiment, the rotation of the indoor fan 6 is intermittently controlled, but the rotation of the indoor fan 6 may be continuously controlled. Further, the rotation speed of the indoor fan unit 6 may be set to 600 rpm or less. That is, when the rotation of the indoor fan unit 6 is continuously controlled, ozone is sufficiently diffused into the indoor unit even if the rotation speed is not so increased.

[0020]

According to the present invention described above, the following effects can be obtained. The control method of the air conditioner of the present invention,
When an internal clean operation signal is received by the remote controller, the open / close panel is closed, the upper and lower wind direction plates are upwardly blown, and the short circuit panel is downwardly formed to form a suction port for the blown air. While the dust collector is on-controlled, the rotation of the indoor fan is controlled and the ozone generated by energizing the electric dust collector is diffused inside the indoor unit. The air can be sucked into the indoor unit from the air inlet formed by the section.
Therefore, while the amount of air blown into the room is reduced, the ozone generated by energizing the electric heater is efficiently diffused into the interior of the indoor unit, thereby effectively deodorizing and sterilizing the interior of the indoor unit to improve comfort. There is an effect that it can be achieved.

According to the control method of the air conditioner of the present invention, when an internal clean operation signal is received by the remote controller during operation stop or operation, the indoor fan unit is stopped, the opening / closing panel unit is closed, and the vertical wind direction plate unit is closed. And the short circuit panel is directed downward to form a suction port for the blown air. Thereafter, the electric dust collector is turned on for a predetermined time, while the indoor fan is turned on for the predetermined time. Intermittent or continuous rotation control,
Since the ozone generated by energizing the electric precipitating unit is diffused into the indoor unit, comfort is further improved by the above-described control during operation stop or operation in addition to the above-described effects. In particular, when the indoor fan rotates intermittently, the amount of ozone diffused into the room can be extremely reduced, so that there is a great effect on deodorization and sterilization inside the indoor unit.
