As shown in FIG. 4, a window 75 is formed.
A transparent or translucent resin sheet or the like is attached to 5.

The air conditioner has an air outlet 21.
An ion generator (not shown) is installed in order to supply negative ions on the air blown out from. The display device 31 includes a plurality of LED columns 3 as shown in FIG.
The display unit 1A to 31C for displaying the wind direction (wind direction monitor) and the display unit (ion monitor) 31D for displaying the generation of ions are provided.

The display section 31D also serves as a filter sign, and when the dirt of the filter material 14 is detected, the fact of the dirt of the filter material 14 is displayed.

Therefore, it is possible to judge when the filter material 14 should be replaced because the filter material 14 becomes dirty just by looking at the display portion 31E. Also, this filter sign does not indicate ion generation until the filter material 14 is cleaned of dirt. It is presumed that the filter material 14 is contaminated when the total operating time reaches a predetermined time, for example, by the cumulative operating time of the cooling and heating operation or the like. Therefore,
The dirt on the filter material 14 corresponds to the time to replace the filter material 14.

The plurality of LED rows 31A to 31C indicate the wind direction of the air flow from the air outlet 21, but when the ions are generated, the ions flow along with this air flow.
Each of the LED rows 31A to 31C can indicate the emission direction of ions.

For example, in FIG. 7, the LED column 3 in the left column
When 1A is turned on, the air flow containing ions is blown out to the left from the air outlet 21, and the central vertical LED row 3
When 1B is turned on, the air flow containing ions is blown out from the air outlet 21 to the center, and the LED row 31 in the right vertical column is emitted.
When C is turned on, the air flow containing ions is blown out rightward from the air outlet 21.

Therefore, the direction in which the ions are flowing can be easily confirmed only by looking at the lighting state of each of the LED rows 31A to 31C.

If the amount of ions generated from the ion generator 25 is substantially constant, the amount of ions blown out increases when the wind speed increases.
By changing the display form of the columns 31A to 31C,
The amount of released ions can be displayed. For example, each L
The display form of the ED columns 31A to 31C is that the LED columns 31A to 31C indicating the flow direction of the air flow are continuously turned on and off with a time shift from the upper LED to the lower LED, and the wind speed is changed. As time increases, the amount of time lag is reduced.

According to this, the user can select each LED row 31
Only by looking at the display forms of A to 31C, it is possible to confirm how much ions are flowing.

In the present embodiment, the display device 31 is fixed at a substantially central position in the longitudinal direction of the frame 71, and the suction grill 1
Since the window 75 is provided at a position corresponding to the display device 31 of No. 1, when the suction grill 11 is closed, this window 7
