[Prior art] Fig. 4 shows, for example,
It is a circuit configuration diagram showing a conventional remote control device for an air conditioner disclosed in the publication, 1 is a key matrix of the remote control device, 2 is a microprocessor, and the key matrix 1 is input ports 3a, 3b, first output port 4a,
It is connected to the second output port 4b by a signal line. 5a and 5b are resistors 1 and 2 and 6 that pull down the signal lines from the key matrix 1 to the input ports 3a and 3b of the microprocessor 2 to ground.
is a logical sum gate which outputs the logical sum of the signal lines input from the key matrix 1 to the input ports 3a and 3b of the microprocessor 2 to the piezoelectric buzzer 7. Reference numerals 8a and 8b denote a first display LED and a second display LED, which are connected to the collector side of the transistor I9a and the transistor II9b, and are connected to the microprocessor 2 through the base.
The emitters of the transistor I9a and the transistor II9b are connected to the ground. A power supply 10 is connected to the microprocessor 2.

Next, the operation will be explained. First output port 4a, second output port 4b of microprocessor 2
When a signal is output to the microprocessor 2, the signal is input to the input ports 3a and 3b of the microprocessor 2 depending on the pressed state of the key of the key matrix 1. In other words, the state of the key matrix 1 can be determined from the states of the first output port 4a, second output port 4b, and input ports 3a, 3b of the microprocessor 2, and the state of the third output port 4c of the microprocessor 2 can be determined based on the state of the key matrix 1. A signal is output from the fourth output port 4d to drive the transistor I9a and transistor II9b, and the first display LED 8a and second display LED 8b are turned on, and the operation details are displayed to the person operating the key matrix 1 for confirmation. It has the function of causing When signals are input to the input ports 3a and 3b of the microprocessor 2, they are simultaneously input to the OR gate 6, and the output of the OR gate 6 causes the piezoelectric buzzer 7 to sound. That is, if any switch in the key matrix 1 is pressed, the piezoelectric buzzer 7 will sound to notify that the switch is pressed.

0004

[Problem to be Solved by the Invention] Since the conventional remote control device for air conditioners is configured as described above, the same sound is always produced when the switch is pressed, regardless of whether it is enabled or disabled in the current operating mode. was outputting. for example,
If you change the timer time during continuous operation, the same sound as a normal valid operation is output, even though the timer time change is not valid unless the timer is running. I thought I had performed an invalid operation, but I did not realize that I had actually performed an invalid operation.

[0005] This invention was made to solve the above-mentioned problems, and when an invalid operation is performed, it can be determined by the sound and the operator can be immediately informed that the invalid operation has been performed. , the purpose is to obtain an air conditioner with an operating device.

[0006]

[Means for Solving the Problems] A control device for an air conditioner according to the present invention includes a driving operation command generating means, and a driving operation command determining means for determining whether the operational command of the driving operation command generating means is valid or invalid. , and driving operation command validity display means for changing the reception sound of the operation command according to the result of the driving operation command determining means.

[0007]

[Operation] The air conditioner having the operating device according to the present invention can determine whether the operating command is valid or invalid based on the operating state when the operating command is input, based on the received sound of the operating command. It is possible to immediately notify the operator that an invalid operation has been performed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a control block diagram of an air conditioner having an operating device according to the present invention, FIG. 2 is an electric circuit diagram thereof, and FIG. 3 is a flowchart showing its operation. Figures 1 and 2
