In this air conditioner (1), a service person or the like may inspect various abnormalities, and the inspection control operation will be described.

First, as shown in FIG. 4, the wireless remote controller (5)
In step ST1, when the input key (52a) or the check button (52b) is pressed, the input of the operation signal is detected.
Next, in step ST2, it is determined whether the check button (52b) is pressed. If the check button (52b) is not pressed, that is, if the input key (52a) is pressed, the check button (52b) is pressed. ) Waits at step ST2 until is pressed.
When the inspection button (52b) is pressed, the process moves from step ST2 to step ST3, and an inspection signal is transmitted from the transmitter (55) of the wireless remote controller (5) to the indoor unit (4). That is, when the inspection button (52b) is pressed to input the inspection operation signal, the inspection control means (51b) processes the inspection operation signal and outputs the inspection signal, and the inspection signal is transmitted to the indoor unit (4). ) And returns to step ST1.

On the other hand, in the indoor unit (4), as shown in FIG. 5, the receiving unit (44) receives various signals from the wireless remote controller (5) and the CPU (41) takes in the signals. First, it is determined in step ST11 whether or not it has been received,

Then, as described above, the display section (45) performs a normal display,
For example, in the case of air conditioning display, the first light emitting diode (61)
Lights up.

On the other hand, if the inspection signal is received in step ST12, the determination becomes YES and the process proceeds to step ST14. That is, since the detection signals of various sensors are input to the CPU (41) of the indoor unit (4) to recognize the presence or absence of various abnormalities, when the inspection signal is received, the inspection processing means (41b). Checks the operating status and detects an abnormality, it outputs an abnormality display signal corresponding to the abnormality and the step
In 14 the display (45) has four light emitting diodes (61)
Flashes (64) to display the details of the error, and the process returns to step ST11. For example, when an abnormality of the drain water level system has occurred, as shown in FIG. 3, the preset classification code and content code are set to four light emitting diodes (61) to (6).
4), specifically, only the fourth light emitting diode (64) is lit in the first lighting (see FIG. 3 (a)), indicates the classification code “A”, and is temporarily turned off (see FIG. 3 ( b)), the third and fourth light emitting diodes (6
3) and (64) are lit (see FIG. 3 (c)) to indicate the content code "3", and then all the light emitting diodes (61)
(64) goes out (see FIG. 3 (d)). Based on the classification code and the content code, the service person or the like grasps the content of the abnormality based on the code table created in advance and performs maintenance or the like.

Further, as another embodiment, instead of displaying the abnormality content by the light emitting body (6) in the above-mentioned embodiment, the abnormality content may be displayed by the reception confirmation buzzer (7).

That is, the buzzer (7) is configured to emit two types of sounds, for example, to generate "beep" and "beep". Further, the buzzer (7) is configured to emit eight sounds in sequence based on the abnormality display signal of the inspection processing means (41b) and to notify of 64 kinds of abnormality contents in combination with the two abnormal sounds. There is. Then, as a specific example, "H • 0" → "pippipipipipi" ... H is represented, and "pipipipipipipipi" ... 0 is expressed.

"H • 1" → "pipipipipipi" ... Represents H and "pipipipipipipi" ...

“H · 6” → “pi-pi-pi-pi-pi” ... Represents H and represents “pi-pi-pi-pi-pi”.

Therefore, the service person or the like can grasp the abnormality content from the classification code “H” and the content code “1”.

Therefore, when an inspection signal is transmitted from the wireless remote controller (5) to the indoor unit (4) and an abnormality in the air conditioning operation is detected based on the inspection signal, the indoor unit (4) displays the content of the abnormality by light or sound. By doing so, the service person or the like can grasp the details of the abnormality only by operating the check button (52b). As a result, the details of the abnormality can be known at a glance, and maintenance and the like can be performed quickly and accurately, so that the serviceability can be improved.

In particular, since the wireless remote controller (5) does not have a receiving function, it is possible to improve serviceability by displaying the content of abnormality on the indoor unit (4).

Further, the light emitting diodes (61) to (64) have conventionally been used to display operation and the like, and the buzzer (7) has been conventionally provided for confirmation of reception, and any new display means should be provided. Since the abnormal display is displayed without any increase, the serviceability can be improved without increasing the number of parts.

Although the light emitting body (6) uses four light emitting diodes (61) to (64) in the above embodiment, three or five or more various light emitting elements may be used. Color change or the like may be used. Further, the sounding body is not limited to the buzzer (7).
