2. Description of the Related Art FIG. 5 shows, for example,
FIG. 2 is a block diagram of a circuit configuration for displaying an abnormality by a conventional remote control device disclosed in the above publication. In the figure, 1 is an air conditioner for the purpose of displaying abnormalities, and 2 is a device for remotely controlling this air conditioner, which detects abnormalities in the air conditioner and controls the display of the degree of abnormality, cause, and air conditioner number. Receiving section 3a, rank storage section 3b, rank determining section 3c, and display switching section 3
d, a transmission circuit 4 that transmits the contents of the microcomputer 3 to the air conditioner 1, and a display circuit 5 that displays the degree of abnormality, cause, and air conditioner number determined by the microcomputer 3. There is.

Next, the operation will be explained along the flowchart of FIG. When the air conditioner 1 stops for some reason, an abnormality signal is detected by the abnormality receiving section 3a of the microcomputer 3, the system stops at step 44, and it is determined at step 45 whether the content of the abnormal stop is an abnormality in the own system. In step 45, it is determined whether there is an abnormality in another system, and in step 50, it is determined whether it is a warning display. When either one is received, the rank determining section 3c compares it with the data in the rank storage section 3b, and the display switching section 3d compares the received air conditioner with the data stored in the rank storage section 3b. The display circuit 5 displays the machine number and abnormality code. In the case of an abnormality other than the above, it is not displayed.

[Problem to be Solved by the Invention] Since the abnormality display by the conventional air conditioner remote control device is configured as described above, it is not possible to display malfunction of the microcomputer due to external noise or abnormal operation such as runaway. I couldn't make a decision without stopping. Conventional devices cannot determine abnormal operation due to malfunction or runaway of the microcomputer, and cannot notify the user of the abnormality unless the microcomputer is stopped.

[0005] This invention was made to solve the above-mentioned problems, and when the microcomputer malfunctions or goes out of control due to external noise, etc., the remote control can display a warning message to the user and notify the user of the abnormality. The purpose is to notify by display and audio notification (buzzer).

[0006]

[Means for Solving the Problems] A remote control device for an air conditioner according to the present invention includes an output signal transmitting means for transmitting a signal by the output of a port of a microcomputer, and a power source for transmitting a signal indicating the power ON/OFF state. A signal transmitting means, a receiving means for receiving the transmitted signal with a remote control device, a received signal determining means for determining whether the received signal is normal or not, and a warning/abnormality display means for warning and displaying an abnormality when the microcomputer is abnormal. and a voice notification means for giving a voice notification in the event of an abnormality.

[0007]

[Operation] The air conditioner remote control device according to the present invention uses a microcomputer in the remote control device to determine whether the air conditioner is abnormally operating or stopping due to external noise, etc., and displays an abnormality warning. , abnormality display, and audio notification.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In Figures 1 and 2, 6 is the power supply and the microcomputer 7 on the main body side.
3 is a microcomputer for controlling the remote control device 2; and 10 is a receiving device that transmits signals from the air conditioner 1. It consists of a receiving section 11 for receiving the signal sent from the section 6, and a signal detecting section 12 for detecting the signal received by the receiving section 11 with the microcomputer 3. 13 is a determination unit that determines whether the microcomputer 7 of the air conditioner is normal or not based on the state of the signal; received signal determination means 13a; 14 is a control unit that controls the remote control device 2 according to the determined content; 15 is an abnormality It consists of an abnormality warning section 16 for displaying a warning of an abnormality when an abnormality occurs, an abnormality display section 17 for displaying an abnormality and prompting to reset the power supply when an abnormality occurs, and a display circuit 5 for displaying a warning display and an abnormality display. Warning abnormality display means; 19 is a sound notification means comprising a sound notification section 21 for notifying an abnormality through a buzzer 20 when an abnormality occurs; 22 is a timer for controlling the time of the warning display, abnormality display, and audio notification.

FIG. 3 is a flowchart of one embodiment. FIG. 4 is an example of a time chart of the operation based on FIG. 3. Depending on whether or not a voltage is applied to the power supply Vcc of the microcomputer 7 of the air conditioner 1, it is determined whether the power supply voltage is being applied. When a voltage is applied, a signal with a specific period is emitted. The program is started by receiving a signal indicating the power state at the remote control device. Step 23 is the power supply V of the microcomputer 7 of the air conditioner 1.
When a voltage is applied to cc, a signal with a specific period is transmitted, so if the signal is being transmitted, it is determined that the circuit is energized, and if there is no transmission, it is determined that the circuit is not energized. Step 24
If there is no call, it is determined whether an instruction to turn on the operation is issued from the remote control device 2, and if an instruction is issued, the process returns to the start. If an instruction is given, it is determined that there is an abnormality. In step 25, if it is determined in step 24 that the power is on, it is determined whether the transmitted signal from the microcomputer 7 has a constant period or not, and whether or not it is normal. Step 26 is Step 2
If an abnormality is determined in steps 3 and 24, a warning is displayed. For example, "The control circuit is not working properly.
Please turn off the FF or power off”. Step 27 is a timer that counts the warning display display time. Step 28
If the power is turned off due to a warning display and a reset is performed,
Return to start.

In step 29, it is determined whether the count in step 27 has ended. A warning is displayed while the timer is counting. B shown in FIG. 4 is an example. In step 30, it is determined whether the microcomputer once malfunctions but returns to normal later. A shown in FIG. 4 is an example. If it returns to normal, return to the start. In step 31, if the power is not turned off in step 28 during the timer count in step 27 and the microcomputer of the air conditioner is not returned to normal,
Make the display abnormal. For example, "An abnormality has occurred in the control circuit. Please turn off the power." Steps 32, 33, and 34 are similar to steps 27, 28, and 29, and if the power is not turned off in step 33 during the timer count in step 32, an abnormality is displayed during the timer count. C shown in FIG. 4 is an example. In step 35, if the power supply in step 33 is not reset during the timer count in step 32, the buzzer 20 issues an audio notification. A voice announcement is made unless the power is reset in step 36. C shown in FIG. 4 is an example.
