In addition, the display means 100 displays the operating conditions set by the user by the driving operation means 15 under the control of the control means 20 as well as displaying the operation state of the air conditioner.

Hereinafter, the effect of the sound control device and the method of the air conditioner configured as described above will be described.

2A and 2A are flowcharts showing the operation procedure of the acoustic control of the air conditioner according to the present invention, in which S denotes a step in FIGS. 2A and 2B.

First, when power is applied to the air conditioner, the DC power supply unit 10 converts the power supply voltage of the commercial AC power supplied from an AC power input terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each drive circuit. Output to the furnace and the control means 20.

Therefore, in step S1, the DC voltage output from the DC power supply means 10 is inputted from the control means 20, and the air conditioner is initialized. In step S2, operation conditions of the air conditioner desired by the user (cooling, heating, Clean, dehumidification, etc.), the set temperature (Ts), and the indoor discharge amount are inputted by the driving operation means 15, and the current time and the alarm time are inputted by the time input keys of the driving operation means 15.

Subsequently, in step S3, the timer means 25 starts counting the time from the current time input by the driving operation means 15, and outputs it to the control means 20. In step S4, the air conditioner It is determined whether an operation signal for starting an operation (for example, cooling operation) has been input to the control means 20.

As a result of the discrimination in step S4, when a driving signal is input (YES), the control means 20 proceeds to step S5 to perform the driving condition input by the user by the driving operation means 15. The control signal for driving the indoor fan 61 is output to the indoor fan motor driving means 60.

Therefore, the indoor fan motor driving means 60 receives the control signal output from the control means 20 according to the set air volume input by the driving operation means 15 to control the rotation speed of the indoor fan motor to indoor The fan 61 is driven.

When the indoor fan 61 is driven, the indoor air starts to be sucked into the air conditioner through an inlet not shown. In step S6, the indoor air temperature (Tr) sucked through the inlet can be detected. 30 is detected and output to the control means (20).

Subsequently, in step S7, it is determined whether the room temperature Tr sensed by the room temperature sensing means 30 is greater than the set temperature Ts input by the driving operation means 15.

As a result of the determination in step S7, when the room temperature Tr is larger than the set temperature Ts (YES), the room must be cooled. In step S8, a predetermined time after driving the indoor fan 61 in step S5. (Delay time for protecting the compressor; about 3 minutes) is determined, and if the predetermined time has not elapsed (NO), the process returns to the step S5 and until the predetermined time has elapsed, the indoor fan ( Only drive 61).

As a result of the discrimination in step S8, when a predetermined time has elapsed (YES), even if the compressor 41 is driven because the current consumption is constant, there is no problem in the compressor 41, so the control means 20 in step S9. Determines the operating frequency of the compressor 41 according to the difference between the room temperature Tr and the set temperature Ts and outputs a control signal for driving the compressor 41 to the compressor driving means 40.

Therefore, the compressor driving means 40 drives the compressor 41 according to the operating frequency determined by the control means 20.

In addition, in step S10, the control means 20 determines the rotation speed of the outdoor fan motor according to the difference between the room temperature Tr and the set temperature Ts to output a control signal for driving the outdoor fan 51 to the outdoor fan. Output to the motor drive means (50).

Accordingly, the outdoor fan motor driving means 50 drives the outdoor fan 51 according to the rotation speed of the outdoor fan motor determined by the control means 20.

Subsequently, in step S11, the control means 20 determines whether the time counted by the timer means 25 is the alarm time input by the user by the operation operation means 15, and the counter time is not the alarm time. (NO), the process proceeds to step S12 to determine whether the time counted by the timer means 25 is on an hourly basis (for example, 12, 13, 14, 15 o'clock). do.

As a result of the discrimination in step S12, if the counted time is not the hourly time (NO), the process returns to the step S3 and continuously counts the time, repeats the operation of step S3 or less, and the counted time is hourly. In the case of the right angle (YES), the flow advances to step S13 to detect the conductivity changing according to the irradiation amount of light in the photoconductive sensing means 80 to determine whether it is daytime.

At this time, the reason for determining whether it is daytime is to control so that the sound that informs the hourly hour occurs normally during the day and does not occur at night (approximately 21: 00-06: 00 hours), even if the sound of the same volume This is because the user may feel somewhat noisy at night because the sound is different depending on the day and night.

As a result of the discrimination in step S13, when it is not day (NO), no sound is generated, and the process returns to step S3 to continuously count the time, repeating the operation of step S3 or less, and when low (YES). In one case), the process proceeds to step S14, whereby the control means 20 outputs a control signal for generating a sound informing the hourly time to the sound generating means 70.

Accordingly, the sound generating means 70 receives the control signal output from the control means 20 and generates an operation (Cuckoo sound, bird sound, bell sound, etc.) to inform the hourly time through the time sound generator 71. Quit.

On the other hand, if it is determined in step S11 that the time counted by the timer means 25 is the alarm time (YES), the process proceeds to step S15 and the control means 20 generates a sound for informing the alarm time. The control signal is output to the sound generating means 70.

Accordingly, the sound generating means 70 receives a control signal output from the control means 20 and terminates the operation while generating a sound (melody, trumpet sound, etc.) indicating the alarm time through the alarm sound generating unit 73. do.

When the determination result in step S4 is that no operation signal is input (NO) and the determination result in step S7 is when the room temperature Tr is not larger than the set temperature Ts (NO). ), It is not necessary to cool the air conditioner, and the flow proceeds to the step S11 to repeat the operation of the step S11 or less.

According to the acoustic control apparatus and method of the air conditioner according to the present invention as described above, by generating a sound to inform the hourly hour and the alarm time by counting the time according to the current time and the alarm time input by the user There is an effect that can satisfy the user's various desires for, and has an excellent effect that can satisfy the user's preference for sound by automatically adjusting the volume of the sound informing the hourly hour and alarm time every day and night.
