【Example】

Example 1. An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a main body of an indoor unit of an air conditioner. In the figure, 1a is an indoor unit main body, 1b is a receiving unit for receiving a signal from a remote controller (hereinafter abbreviated as a remote controller), 1c is an infrared transmitting unit for transmitting a signal to the remote controller, and 1d is built in the main body side. A microcomputer (hereinafter, referred to as a microcomputer) 1e is a thermistor for detecting a room temperature, and 1f is a power switch of an "operation / stop" air conditioner. FIG. 2 is an operation flowchart of the air conditioner of this embodiment.

The operation of this embodiment will be described. Driving in Figure 1 /
When the stop button 1f is pressed to turn on the power, the power is turned on in step S22 according to the flow of FIG. And the diagnostic result is step S
At 24, it is transmitted to the remote controller side. In this way, a special dedicated diagnostic switch (button) is prepared, and self-diagnosis can be performed without pressing this switch.

Embodiment 2. Another embodiment of the present invention will be described. FIG. 3 is an external view of the wireless remote controller of the air conditioner. In the figure, 3a is a remote control main body, 3b is an infrared diode for transmitting signals to the indoor unit main body, 3c is an infrared receiver for receiving signals from the indoor unit, 3d is an indicator for displaying the operating condition of the indoor unit, 3e is It is a "run / stop" switch for turning on and off the power of the indoor unit, and a microcomputer that determines the signal content of the indoor unit.

The operation of this embodiment will be described. Press the start / stop button 3e on the remote controller shown in FIG.
When a is performed, the operation signal and the accident diagnosis request signal are transmitted from the infrared diode 3b on the remote control side to the indoor unit main body in step S2b. In the main body 1a, a self-diagnosis command is activated immediately after the receiver 1b turns on the indoor unit in step S22, and the microcomputer 1d self-diagnoses the main body in step S23. Then, the diagnostic result is transmitted to the remote controller side in step S24 by the infrared diode 1c. On the remote control side, the infrared receiver 3c receives the signal in step S2c, and the microcomputer 3f receives it in step S2d.
The received code is analyzed in step S2e or the content is displayed in step S2f. In this way, a special dedicated diagnostic switch (button) is prepared, and self-diagnosis can be performed without pressing this switch.

Embodiment 3. Starting the self-diagnosis at the same time by pressing a switch that has a high frequency of operation does not require a dedicated diagnostic push button, and it is effective because the check can be performed without being aware of the diagnostic operation. It's also possible that you don't have to do that often. Therefore, an example of skipping the self-diagnosis will be described. In this embodiment, it is stored in advance in the microcomputer that the self-diagnosis is skipped by pressing a combination of specific switches on the remote controller side, for example, by simultaneously pressing a set temperature and a set temperature. In addition, in this embodiment, "automatic operation" is used as a switch that is frequently operated.
Is set, and therefore, the self-diagnosis signal is transmitted at the same time when the automatic operation is pressed. In addition, the display of the operation status during automatic operation displays the "set temperature" during automatic operation. The structure of the present embodiment is such that the main body is shown in FIG. 1 and the remote controller is shown in FIG. FIG. 4 is an operation flowchart showing the operation of this embodiment.

Next, the operation will be described. The operation of each constituent element on the indoor unit main body side and the remote controller side is the same as that in the second embodiment, and hence the description will be given below based on the operation flowchart, and the description of the hardware constituent elements will be omitted. First, when "automatic operation" of the operation switch 3e on the remote controller side is pressed in step S4a, it is asked in step S4b whether or not the skip stored in the microcomputer 3f at that time is set. As in Example 2, a self-diagnosis request signal is sent together with the automatic operation command signal. In addition, it sends a request signal to send the set temperature during automatic operation. If skipped, only the automatic operation command signal and the request signal for transmitting the set temperature are sent.

On the indoor unit main body side, if not skipped, this is received in step S4e, the automatic operation mode is set in step S4f, and self-diagnosis is performed prior to automatic operation. When skipping, a signal is received in step S4h to enter the automatic operation mode. Then, as in the case where the self-diagnosis result shows no failure, the code of the set temperature is sent to the remote controller side in step 4i. On the remote control side, the received code is analyzed in step S4k, and if there is a failure, the contents are displayed in steps S4m and S4n, and if there is no failure, the "set temperature" for automatic operation is displayed in step S4l.

Example 4. An example will be described in which an operation caused by frequently pressing a switch continues. By doing so, the operability is further enhanced. In the present embodiment, an example in which the subsequent operation differs depending on the operation mode is shown. The indoor unit body and the remote controller are the same as those in the above embodiment. Therefore, the description of the operation of the hardware components will be omitted. FIG. 5 is a flow chart showing the operation of this embodiment. In the figure, a switch with a high operation frequency is a power-on / release switch for "run / stop". Since the operations from step S5a to step S5e are almost the same as those in the second and third embodiments, the description thereof will be omitted. If there is no failure, the operation mode is checked in step S5f. In the automatic operation mode, the "set temperature" is transmitted in step S5g, whereas in the manual operation, the "indoor temperature" measured in step S5h is transmitted in this case. On the receiving remote controller side, if there is no failure, the "set temperature" or the "indoor temperature" of the measurement result is displayed in steps S5k and S51.

Embodiment 5. In the fourth embodiment, the display during manual operation is set to the actually measured "indoor temperature", but this can be changed by operation and may be set to the actually measured "outdoor temperature".

Example 6. In the above embodiment, the self-diagnosis of the indoor unit main body triggered by the pressing of a switch that is frequently operated has been described, but an example in which the transmission system between the indoor unit main body and the remote controller is also diagnosed will be described. Prior to driving, it is investigated at the same time that the remote control function is deteriorated due to a decrease in battery output, a decrease in infrared transmission / reception system capability, an increase in distance, etc. Since the configurations of the indoor unit main body and the remote controller are the same as those in the above example, the description of the hardware operation is omitted. FIG. 6 is a flow chart for explaining the operation of this embodiment. In this example, the frequently used switches are
Use the "Stop" button.

When the "run / stop" switch is pressed in step S6a, the remote function check code is transmitted together with the power-on signal and the self-diagnosis request signal in step S6b. On the main body side, in addition to the steps similar to those of the other embodiments, the remote function check code is analyzed in step S6f, for example, a checksum is calculated, and if the self-diagnosis result is normal, the result is transmitted to the remote control side in step S6g. To do. On the remote controller side, it is possible to determine whether the transmission system is normal or abnormal from the reception result in step S6j.
To display it.

Example 7. In the above embodiment, the required signal is sent from the remote controller, but it is assumed that only a normal single signal such as power-on is sent.
A series of operations may be performed based on the received power-on signal and self-diagnosis signal on the indoor unit main body side that has been received. However, the skip function stored only on the remote control side is received from the remote control side.

Example 8. The above embodiments can be implemented by combining those which do not overlap. For example, the skip mechanism and the automatic / manual operation mode determination mechanism may be implemented at the same time.

[0022]

As described above, according to the present invention, since the self-diagnosis is performed at the same time by the switch having a high operation frequency, the device can be surely diagnosed. Claim 2
According to the invention, since the normal operation is displayed when the diagnosis result is normal, there is an effect that the normal operation can be promptly performed after the diagnosis without burdening the operator. According to the third aspect of the invention, since the display corresponding to the driving state is further displayed if the diagnosis result is normal, there is an effect that the operator need not be aware of the diagnosis at all. According to the invention of claim 4, this operation can be performed from the remote controller side, and the transmission system between the main body remote controllers can be checked at the same time. According to the invention of claim 5, there is an effect that the operation can be further selected as necessary and the time until the operation can be shortened.
