When negative ion increase operation is performed with the ion increase / decrease switch, the ion generator increases the amount of ions generated and displays the increase in the amount of ions generated on the display device. An air conditioner or an air cleaner provided with ion generation amount adjusting means that automatically returns to the ion generation amount before the increase.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In S2 of FIG. 6, if the air conditioner is operating and the ion generator 20 is operating, the process proceeds to S3, and a normal display is performed in which the ion lamp 38 is sequentially turned on from the left according to the amount of negative ions generated. If the ion generator 20 has stopped in S2, it will return to S1 and continue operation.
Next, when the ion operation switch 31 is pressed in S4, the generation of negative ions is stopped in S10, the ion lamp 38 is turned off, and the process returns to S1. If the ion operation switch 31 is not pressed, the process proceeds to S5.
[0008]
In S5, it is determined whether or not the ion increase / decrease switch 32 is pressed. In S6, the power sent to the ion generating circuit 42 by the input power control circuit 44 in S6 is changed from 80% in normal time to 100%. By increasing the number, the amount of negative ions generated from the radiation electrode 14 is increased, the amount of the ion lamp 38 is increased, and the timer 49 is started.
If the ion increase / decrease switch 32 is not pressed, the process returns to S3 and the normal ion generation operation is continued.
[0009]
In S7, it is determined whether or not the ion increasing / decreasing switch 32 is pressed again. In the case of pressing, the power of the ion generating circuit 42 is set to 80% in S9 and the ion lamp 38 is switched to the normal display and the process returns to S3. If 20 minutes have passed without pressing the ion increase / decrease switch 32, the process automatically proceeds from S8 to S9 and returns to S3 to continue the normal operation.
[0010]
Therefore, the user can increase the amount of negative ions generated according to the mood, physical condition, and preference at that time, so that the user himself can recover his mood and manage his physical condition. It can be easily adjusted and is very convenient to use.
In addition, the dynamic display using the ion lamp 38 can inform the user of the increased amount of negative ions in an easy-to-understand manner.
[0011]
After the negative ion generation amount increases, the negative ion generation amount can be easily reduced to the normal generation amount before the increase if necessary, and automatically after a predetermined time from the start of the negative ion increase. Therefore, the negative ions are excessively generated for a long time, thereby causing harm to the human body and preventing a large amount of dust from adhering to the wall around the device.

In S6, the power sent to the ion generating circuit 42 by the input power control circuit 44 in S6 is changed from 80% in normal time to 100%. By increasing the number, the amount of negative ions generated from the radiation electrode 14 is increased, the amount of the ion lamp 38 is increased, and the timer 49 is started.
If the ion increase / decrease switch 32 is not pressed, the process returns to S3 and the normal ion generation operation is continued.
[0039]
In S7, it is determined whether or not the ion increasing / decreasing switch 32 is pressed again. In the case of pressing, the power of the ion generating circuit 42 is set to 80% in S9 and the ion lamp 38 is switched to the normal display and the process returns to S3. If 20 minutes have passed without pressing the ion increase / decrease switch 32, the process automatically proceeds from S8 to S9 and returns to S3 to continue the normal operation.
[0040]
In this embodiment, the air conditioner has been described. However, if an activated carbon filter is used instead of the heat exchanger 9, it can be directly applied to an air purifier. In this embodiment, the operation unit 27 is connected to a wireless remote controller. 26 may be provided integrally with the unit.

In this way, the user can increase the amount of negative ions generated according to the mood, physical condition, and preference at that time, so that the user can recover their mood and manage their physical condition. However, it can be easily adjusted and is very convenient to use.
In addition, the dynamic display using the ion lamp 38 can inform the user of the increased amount of negative ions in an easy-to-understand manner.
[0042]
After the negative ion generation amount increases, the negative ion generation amount can be easily reduced to the normal generation amount before the increase if necessary, and automatically after a predetermined time from the start of the negative ion increase. Therefore, the negative ions are excessively generated for a long time, thereby causing harm to the human body and preventing a large amount of dust from adhering to the wall around the device.
[0043]
Further, since the ion increase / decrease switch 32 is constituted by a momentary switch, even if the ion increase operation is automatically returned to the normal operation after the ion increase operation, the ion increase operation can be easily performed again with a single press.
[0044]
