Generally, a liquid crystal display is used as the display 19.

As shown in FIG. 3, the air conditioner 1 has driving devices 10a, 10b for the indoor heat exchangers 7a, 7b and the indoor fans 8a, 8b in response to an input signal from the remote controller 16. Control device 21 for controlling wind direction adjusting blades 13a and 13b and light emitting diodes 15a and 15b
Is provided. That is, the control device 21 responds to an input signal from the air volume adjustment button 17 of the remote controller 16
By controlling the driving devices 10a and 10b, the indoor fans 8a and 8b are controlled.
The air volume of b is adjusted in three stages (strong, weak, fine).

The operation of the above configuration will be described below.

When a person in the room 2 operates the air-conditioning function selection button 18 of the remote controller 16 to select a normal air-conditioning function, the control device 21 responds to an input signal from the remote controller 16 to control the two light-emitting diodes 15a and 15b. Are turned off, and the air flow rates of both indoor fans 8a and 8b are set to be equal.
As shown in FIG. 2, both wind direction adjusting blades 13a and 13b are inclined at the same inclination angle α.

At this time, when the air volume adjustment button 17 of the remote controller 16 is operated to set the air volume of both indoor fans 8a, 8b to "strong", strong air blows out from both air outlets 6a, 6b, Both zones A and B in the room 2 are uniformly air-conditioned. As described above, since both the light emitting diodes 15a and 15b are turned off, the person in the room 2 can quickly confirm that the normal air conditioning function is selected by viewing both the light emitting diodes 15a and 15b. And can be accurately grasped. In addition, even when the air volume is set to “weak” or “fine” by the air volume adjusting button 17, both zones A and B are similarly air-conditioned.

When the air conditioning function selection button 18 is operated to select the zone A air conditioning function, the control device 21 turns on one light emitting diode 15a and turns on the other light emitting diode 15a in accordance with an input signal from the remote controller 16. Light emitting diode 1
5B is turned off, the air flow rate of one indoor fan 8a is increased by a fixed rate, and the air flow rate of the other indoor fan 8b is changed to a preset air flow (for example, "weak").
As shown in FIG. 1, one wind direction adjusting blade 13a is inclined at an inclination angle α and the other wind direction adjusting blade 13b
Is swung until it is vertical (fully open).

At this time, if the air volume adjustment button 17 is operated to set the air volume of both indoor fans 8a and 8b to "strong", the strong air blown at a certain rate increased from one of the air outlets 6a and the other is blown out. A predetermined air volume (for example, “weak”) blows out from the air outlet 6 b of the room 2, so that one zone A of the room 2 is locally air-conditioned. As described above, since one light emitting diode 15a is turned on and the other light emitting diode 15b is turned off, a person in the room 2 can select the zone A air-conditioning function by viewing both light emitting diodes 15a and 15b. Can be quickly and accurately grasped.

At this time, as shown in FIG. 1, the other wind direction adjusting blade 13b has swung to the vertical position.
Most of the air-conditioning air blown out from the other air outlet 6b goes to the back side of the other wind direction adjusting blade 13b and is immediately sucked into the suction port 5 and circulated. Then, the air flows into the one indoor heat exchanger 7a, so that the air conditioning in the one zone A is performed even more intensively (independently).

Similarly, when the air conditioning function selection button 18 is operated to select the zone B air conditioning function, the control device 21
In response to an input signal from the remote controller 16, the other light emitting diode 15b is turned on and the one light emitting diode 15a is turned off, the air flow of the other indoor fan 8b is increased by a certain ratio, and the air flow of the one indoor fan 8a is increased. Is changed to a preset air volume (for example, "weak"), the other wind direction adjusting blade 13b is inclined at an inclination angle α, and one wind direction adjusting blade 13a is swung until it becomes vertical (fully open).

At this time, air-conditioning air having a blowing rate increased by a certain rate is blown out from the other air outlet 6b, and air-conditioning air having a predetermined air flow (for example, "weak") is blown out from the one air outlet 6a. The other zone B of the room 2 is locally air-conditioned. Thus, the other light emitting diode 15b is turned on and the one light emitting diode 15b is turned on.
Since a is turned off, the person in the room 2 can quickly and accurately recognize that the zone B air conditioning function is selected by viewing both the light emitting diodes 15a and 15b.

As described above, both light emitting diodes 15a,
By visually checking 15b, it is possible to quickly and accurately grasp which of the normal air conditioning function, the zone A air conditioning function, and the zone B air conditioning function is being performed. Even if there is a mistake, the operator can immediately notice the erroneous operation and correct it.

When the normal air-conditioning function is selected by operating the air-conditioning function selection button 18 on the display of the remote controller 16,
"Normal" is displayed, when the zone A air-conditioning function is selected, "zone A" is displayed, and when the zone B air-conditioning function is selected, "zone B" is displayed. One of “strong”, “weak”, and “fine” is displayed according to the selected air volume.

According to this, when one of the indoor fans 8a breaks down or becomes abnormal, one of the abnormality detecting devices 23a
Thus, an abnormality of one indoor fan 8a is detected. Based on this detection, the control device 21 blinks one light emitting diode 15a every 0.5 seconds. At this time, the blinking time (blinking cycle) of one of the light emitting diodes 15a is managed by the reference timer 24.

Similarly, when the other indoor fan 8b breaks down or becomes abnormal, the abnormality of the other indoor fan 8b is detected by the other abnormality detecting device 23b. Light emitting diode 15b
Flashes every 0.5 seconds. At this time, the blinking time (blinking cycle) of the other light emitting diode 15b is determined by the reference timer 2.

The light emitting diodes 15a and 15b have a function of blinking alternately every 0.5 seconds.

According to this, when the replacement time of the air filter 12 has been reached, the cumulative operation time of one indoor fan 8a measured by the timer 26a for one cumulative time and the timer 26b for the cumulative time of the other are measured. Since the total time with the cumulative operation time of the other indoor fan 8b reaches a certain time, the control device 21
5a and 15b are alternately blinked every 0.5 seconds.

As described above, both light emitting diodes 15a,
By alternately blinking 15b, it is possible to indicate that the total time of the cumulative operation time of one indoor fan 8a and the cumulative operation time of the other indoor fan 8b has reached a certain time, and the two light emitting diodes can be displayed. By visually observing 15a and 15b from inside the room 2, it is possible to quickly and accurately grasp that the time to replace the air filter 12 has come.

Hereinafter, the control process by the control device 21 will be described with reference to flowcharts shown in FIGS. 4 and 5 and a block diagram shown in FIG.

Flashes every second.

Then, the presence / absence of abnormality of the other indoor fan 8b is detected by the other abnormality detection device 23b (step-11). If the abnormality is normal, the total time obtained in step-3 reaches a predetermined time. It is determined whether or not it has been performed (step-12). If the predetermined time has not been reached, it is determined whether the air conditioning function selection button 18 has selected the zone B air conditioning function (step-13). If the zone B air conditioning function has been selected, condition B is executed (step 13). At the same time, the other light emitting diode 15b is turned on (step-15). The above condition B has the following contents. Condition B: The amount of air blown by the other indoor fan 8b is increased by a certain ratio, and the amount of air blown by the one indoor fan 8a is changed to a preset amount of air. The other wind direction adjusting blade 13b is inclined at an inclination angle α, and the one wind direction adjusting blade 13a is made vertical.

If the total time has reached a predetermined time in the step-12, it is determined whether or not the count of the reference timer 24 is 0.5 seconds or more (step-20).
If it is longer than 0.5 seconds (that is, 0.5 to 0.9 seconds), the other light emitting diode 15b is turned off (step-18), and if it is shorter than 0.5 seconds (that is, 0 to 0 .0 seconds).
In the case of 4 seconds), the other light emitting diode 15b is turned on (step-15). Thus, the other light emitting diode 15b blinks every 0.5 seconds. At this time, one of the light emitting diodes 15 in steps -8 to 10 is used.
The blinking of "a" and the blinking of the other light emitting diode 15b in the above-mentioned steps 15, 18, and 20 are alternately performed.
