Hereinafter, the operation control device of the air conditioner configured as described above and the operational effects of the method will be described.

4A and 4B are flowcharts showing the operation control operation procedure of the air conditioner according to the present invention, in which S denotes a step in FIGS. 4A and 4B.

First, when power is applied to the air conditioner, the DC power supply unit 50 converts the power supply voltage of the commercial AC power input from the AC power input terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving time. Output to the furnace and control means (60).

Therefore, in step S1, the DC voltage output from the DC power supply means 50 is inputted from the control means 60 to initialize the air conditioner. In step S2, the key provided in the operation operation means 55 is manipulated. The operation function of the air conditioner (cooling, heating, cleaning, dehumidification, artificial intelligence, etc.), the set temperature (Ts), the air volume, and the wind direction are input to the control means 60.

Subsequently, in step S3, it is determined whether the blood pressure measuring switch 25 for measuring the user's blood pressure and pulse rate is turned on, and when the blood pressure measuring switch 25 is not on (NO), the blood pressure measuring switch 25 The operation of step S3 or less is repeated while keeping the air conditioner in the operation standby state until it turns on.

As a result of the discrimination in step S3, when the blood pressure measurement switch 25 is turned on (YES), the electrocardiogram detecting means is performed in step S4 to measure the blood pressure and the pulse rate of the user. Detected by 70 and output to the control means 60.

The method for detecting an electrocardiogram of a user may include: when a finger is in contact with the blood pressure measuring switch 25, the finger in contact with the blood pressure measuring switch 25 is a negative electrode and a bottom surface of the opposite hand holding the remote controller main body 20; Since the current flows through the anode, the electric potential generated at the contraction of the heart is detected by the ECG sensing means 70, which is an electrode sensor mounted inside the blood pressure measuring switch 25.

Then, the pulse transmitted to the finger at the time of contraction of the heart is detected by the pulse detection means 65 and output to the control means (60).

In the method of detecting a user's pulse, when a finger touches the blood pressure measuring switch 25, light is generated from a photosensor, which is a pulse sensing means 65 mounted inside the blood pressure measuring switch 25, and The wavelength of the generated light strikes the hemoglobin present in the blood in the finger and detects the reflected light signal to detect the user's pulse.

Therefore, the control means 60 detects the pulse transfer times Ta and Tb, in which the pulse generated at the contraction of the heart is transmitted to the finger.

Subsequently, in step S5, it is determined whether the pulse transfer times Ta and Tb have been detected. If the pulse transfer times Ta and Tb are not detected (NO), the process returns to the step S4 to perform the operation of step S4 or less. Repeat.

On the other hand, when the pulse transmission times Ta and Tb are detected (YES) as a result of the discrimination in step S5, the flow advances to step S6 to control the pulse transmission times Ta and Tb detected in step S4. In the memory built into the memory 60), and in step S7, the pulse transfer time Tc, Td from the second pulse at the moment when the user presses the blood pressure measuring switch 25 to an arbitrary time is detected.

Subsequently, in step S8, the time t for calculating the user's pulse rate and the pulse rate P are started to be counted. In step S9, it is determined whether the pulse transmission time Tc, Td from the second pulse to an arbitrary time is detected. Determine.

As a result of the discrimination in step S9, when pulse delivery times Tc and Td are not detected (NO), the flow returns to step S7 to repeat the operations of step S7 and below, and pulse delivery times Tc and Td. If YES is detected (YES), the flow advances to step S10 to call READ the pulse transfer times Ta and Tb stored in the memory of the control means 60.

Then, in step S11, the control means 60 compares the called pulse transmission time Ta and Tb with the pulse transmission time Tc and Td detected up to an arbitrary time in the second pulse, thereby comparing the actual blood pressure values Bh and Bl. ), And in step S12 it is determined whether the blood pressure measuring switch 25 is turned off in order to measure the pulse rate of the user.

As a result of the discrimination in step S12, when the blood pressure measuring switch 25 is not turned off (NO), the flow returns to step S8 to continue the pulse rate P and the time t detected until the pulse rate is detected. When the blood pressure measuring switch 25 is turned off (YES) while the counter is countered, the operation proceeds to step S13 and the pulse rate (P) up to the present time when the finger touches the blood pressure measuring switch 25 is reached. ) And the time required (t).

Subsequently, in step S14, the calculated pulse rate P and the required time t are substituted into the following Equation (1) to measure the pulse rate Pm per minute.

In step S15, the pulse rate per minute Pm measured in step S14 and the blood pressure values Bh and Bl measured in step S11 are displayed on the display means 120 under the control of the control means 60. In S16, it is determined whether the measured blood pressure values Bh and Bl are equal to or less than the predetermined blood pressure values B2 (B1; B1 = 80 + 10 and Bh = 110 + 10) preset in the control means 60.

As a result of the discrimination in step S16, when the blood pressure values Bh and Bl are not equal to or less than the predetermined blood pressure value B2 (NO), the flow rate measured in step S17 is passed to the control means 60. It is determined whether or not the predetermined blood pressure value (B3; B1 = 90 + 10, Bh = 120 + 10) set in advance.

As a result of the discrimination in step S17, when the blood pressure values Bh and Bl are equal to or less than the predetermined blood pressure value B3 (YES), the blood pressure of the user is 80 to 130 mmHg. Therefore, the control means 60 moves to the indoor fan ( 9) outputs a control signal to the indoor fan motor driving means 110 to control the 'medium' speed.

Therefore, the indoor fan motor driving means 110 controls the rotation speed (rpm) of the indoor fan motor under the control of the control means 60 to rotate the indoor fan 9 at a 'medium' speed, step S19. The control means 60 determines the operating frequency of the compressor 81 to 95 Hz and outputs a control signal for driving the compressor 81 to the compressor driving means 80.

Accordingly, the compressor driving means 80 drives the compressor 81 according to the operating frequency (95 Hz) determined by the control means 60.

Subsequently, in step S20, it is determined by the driving operation means 55 whether the automatic driving mode has been inputted, and when the automatic driving mode is not input (NO), the operation returns to the step S16 to perform the operation of step S16 or less. Repeat.

As a result of the determination in step S20, when the automatic driving mode is input (YES), the operation operation of the air conditioner by the user's pulse rate and blood pressure is terminated.

On the other hand, when the blood pressure values Bh and Bl are equal to or less than the predetermined blood pressure value B2 (YES), the blood pressure of the user is 70 to 120 mmHg. Therefore, the control means 60 proceeds to step S30. A control signal for controlling the fan 9 at a speed of 'about' is output to the indoor fan motor driving means 110.

Accordingly, the indoor fan motor driving means 110 controls the rotation speed (rpm) of the indoor fan motor under the control of the control means 60 to rotate the indoor fan 9 at a speed of about 'step', and step S31. The control means 60 determines the operating frequency of the compressor 81 as 70 Hz and outputs a control signal for driving the compressor 81 to the compressor driving means 80.

Accordingly, the compressor driving means 80 proceeds to step S20 and repeats the operations of step S20 and below while driving the compressor 81 according to the operating frequency (70 Hz) determined by the control means 60.

If the blood pressure values Bh and Bl are not equal to or lower than the predetermined blood pressure value B3 (NO), the user's blood pressure is 90 to 140 mmHg. ) Outputs a control signal to the indoor fan motor driving means 110 for controlling the indoor fan 9 at a speed of 'strong'.

Therefore, the indoor fan motor driving means 110 controls the rotational speed (rpm) of the indoor fan motor under the control of the control means 60 to rotate the indoor fan 9 at the speed of 'strong', step S34 In this case, the control means 60 determines the operating frequency of the compressor 81 to 120 Hz and outputs a control signal for driving the compressor 81 to the compressor driving means 80.

Accordingly, the compressor driving means 80 proceeds to step S20 and repeats the operation of step S20 and below while driving the compressor 81 according to the operating frequency 120Hz determined by the control means 60.
