In addition, the microprocessor 14 (control element) is a thing in which the ROM which stored the program previously, the RAM which stores reference data, and the CPU which executes a program are contained in the same package (U879JP by Intel Corporation).

3 and 4 are physical wiring diagrams centering on the microprocessor 14 of the control circuit of the indoor apparatus 1 in the electric circuit of the air conditioner shown in FIG.

FIG. 3 shows wirings on the left side of the microprocessor 14 and FIG. 4 shows wirings on the right side of the microprocessor 14, and FIG. 3 and FIG. 4 are integrated to form the whole wiring diagram.

The same reference numerals are attached to the same components as in FIG. 1 in the drawings.

Referring to FIG. 3, the microprocessor 14 outputs the control data transmitted to the outdoor device 2 from the port P1 and applies it to the serial circuit 23 via the buffer 101.

The serial circuit 23 outputs the control data to the signal line 200 connecting the indoor device 1 and the outdoor device 2.

When the control data is received from the outdoor device 2, the microprocessor 14 inputs from the port P2 via the signal line 200, the serial circuit 23, and the buffer 102.

The serial circuit 23 inputs control data between the signal line 200 and the buffers 101 and 102 using an optical coupler.

The output ports P3 to P6 output the drive signal of the flap motor 19.

Step motor is used for the flap motor 19, and the rotation angle of the flap motor 19 is changed by energizing the coil of the flap motor 19 with the signal output from the output ports P3-P6. There is a number.

In addition, the signal output from the pots P3-P6 is amplified by electric power from the shock absorber 19a until the coil of the flap motor 19 is energized.

The output port P11 outputs the firing signal of the eye fluid 26, the output port P17 outputs a signal for controlling the energization of the heater relay 27, and outputs the output port P18. The signal which sounds the buzzer 103 is output.

All of these signals are amplified by the buffer 19a.

The output port P19 outputs a signal of a DC voltage applied to the fan motor 16.

The signal of this DC voltage consists of columns which changed the impact coefficient of a pulse width.

This pulse train is converted into a direct current voltage in the conversion circuit 104.

This DC voltage is given to the motor power supply circuit 12.

The motor power circuit 120 supplies the DC power of the voltage corresponding to this DC voltage to the motor drive circuit 15.

Therefore, the voltage supplied to the motor drive circuit 15 which changes the impact coefficient of the pulse train output from the pot 19 can be changed.

In addition, since a DC brushless motor is used for the fan motor 16 later, when the voltage supplied to the motor drive circuit 15 is changed, the rotation speed of the fan motor 16 can be changed.

In addition, the conversion circuit 140 is mainly composed of a transistor, a resistor and a smoothing capacitor.

The input port P21 inputs a signal for controlling the energization timing of the fan motor (three-phase brushless electric motor) 16.

This signal is obtained when the current flowing through each stator winding of a three-phase brushless motor changes its polarity around the center point, and is obtained six times in one revolution of the motor.

The circuit which acquires this signal is assembled to the motor drive circuit 15 (hybrid IC KA16 KA160 made by Sanyo Denki).

In addition, the motor drive circuit 15 includes an inverter circuit in which six power transistors are connected in a three-phase bridge, and a switching circuit for performing high-speed ON / OFF of these power transistors (primarily between base emitters of power transistors). Circuit for shortening the discharge time of accumulated charge) is assembled.

Therefore, the fan motor 16 can be rotated by turning this power transistor ON / OFF sequentially according to the rotation angle of the rotor of the electric motor by a combination of predetermined ON / OFF. The ON / OFF signal of each power transistor symbolized by this ON / OFF combination is output from the output ports P22-P27 of the microprocessor 14.

The microprocessor 14 determines a rotation angle of the rotor by performing a predetermined operation from the signal (time between the signal and the signal) input from the port P21, and then outputs the ON / OFF signal for this rotation angle. Output from the (P22)-(P27) to the motor drive circuit 15.

Next, referring to FIG. 4, the output of the room temperature sensor 20 is provided to the port P51 of the microprocessor, the output of the heat exchanger temperature sensor 21 to the port P50, and the illuminance to the port P49. The output of the detection sensor 105 (CdS) is output to the port P48 and the output of the temperature sensor 22 is output.

These outputs are A / D (analog / digital) converted at the ports P51, P50, P49 and P48 and then stored as data in RAM in the microprocessor 14.

The switch board 17 is provided with the contacts C1-C4 such as total stop, operation, trial run, fault diagnosis, and the like, and the slider 17a slides left and right by manual operation.

The potentials of the contacts C1-C4 are given different potentials in four steps by the resistors 106-108 and the voltage of 5V.

Therefore, by judging this potential by the input port P47 (A / D conversion input port), it is possible to determine which contact the sliding member 17a is in contact with.

The fault diagnosis switch 108 is connected to the port 45 of the microprocessor 14.

The remote operation signal received by the receiver 18a is input to the port P42 of the microprocessor 14, and from the ports P36 to P41, the display panel 18 is operated, automatically, cooled, and automatically heated. The signal for turning on the light emitting diode 18b indicating dehumidification is output.

An external ROM 30 is connected to the ports P34, P35 and P44 of the microprocessor 14, and the microprocessor 14 needs the above-described unique data stored in this ROM 30. To read accordingly.

When reading the unique data, the microprocessor 14 resets the external ROM 30 to the signal output from the port P34 as shown in FIG. 5 and outputs the program from the port P35. Then, data is input from the port P44 in accordance with the clock pulse and stored in the internal RAM.

As the external ROM 30, a one-time programmable sequential read only memory is used, for example, Fujitsu MB85419P is used.

6 is a flow diagram showing the main operation of the microprocessor 14.

In this figure, when the plug 10 is connected to an outlet in step S1 to start supplying power, the microprocessor 14 is first initialized in step S2.

Subsequently, in step S3, data stored in the auxiliary ROM 30 is read out and stored in the RAM in the microprocessor 14.

As described above, after the reset signal is applied to the auxiliary ROM 30, the pulse is output at predetermined intervals, and the data in response to the thrust of the pulse is taken from the port P44 and sequentially stored in the RAM. .

Subsequently, the process proceeds to step S4 where the detection of the sensors 20-22 and 105 is inputted, and the data is stored in the RAM.

In the same manner, it is determined from which voltage the switch 17a is in contact with the voltage applied to the port P47, and the data indicating the terminal being in contact is stored in the RAM.

In addition, when a signal (operation information) from the remote control device 60 is input, since a received signal is given to the port P42, a series of operation information received by interrupting the program is input to each data. It is divided and stored in RAM.

In step S5 and step S6, judgment is made as to whether the air conditioner is in operation, whether it has changed from operation to stop, judgment of whether to stop or not. In operation, the process proceeds to step S7 and is stored in the RAM. The operation based on the data obtained is performed.

For example, when the switch 17a is at the terminal of the operation C2 and the heating operation is being performed, first, the lamp indicating the heating is turned on and the operation of the compressor is controlled based on the room temperature and the set temperature (for example, For example, to transmit data for setting the operating capacity of the compressor to an outdoor device).

The microprocessor 41 of the control circuit of the outdoor device 2 is almost the same, but will be described with reference to FIG.

When the outdoor device is powered on (when the plug 10 is inserted into the outlet), the microprocessor starts operation, and each value of the RAM is set to an initial value (initialization S2).

Subsequently, the data of the auxiliary ROM is read and the corresponding RAM value is recorded (SA3).

This state is a state in which the outdoor device is stopped, and is maintained until a signal at the start of operation from the indoor device is given through the signal line 200.

Upon receiving a signal from the indoor device, the indoor device is operated (operation and capability of the compressor 43, the fan motor 45 is operated, the four-way valve 46 and the indoor device based on the signal and the data read from the auxiliary ROM. Control of the state of the valve 47), and the like (S4).

When there is a signal of the operation → stop of the indoor device (for example, a signal of operation → stop of the compressor 45) (for example), after reading the data of the auxiliary ROM again, the signal enters the standby state.

When this condition is not satisfied (no) (when the compressor is stopped or the compressor is running), the operation is continued based on the signal from the indoor device without reading the data of the auxiliary ROM. have.

In the case of the operation stop, the stop state is maintained.

In the air conditioner configured as described above, for example, in the A type, the type of the corresponding remote control device is VR, it has a cooling and heating function, there is no electric heater and the temperature sensor, and the capacity of the device is 2500 Kcal. The type of control device is VR (VS can transmit operation information with more functions than VR, and it can execute many functions of air conditioner), has air-conditioning function, electric heater and temperature sensor. The device's capacity is 2800 Kcal.

There are C type, D type ... in the same shape.

The difference between these models is mainly the number of functions provided, the capacity of the device 2000Kcal, 2500Kcal, 2800Kcal, 3200Kcal and the like.

Therefore, there are as many models as a combination of these, but by selecting a function to be effective and changing the operation capability of the compressor required by the outdoor apparatus according to the capability of the indoor apparatus, a plurality of models can be controlled by a single controller. .

That is, in the control apparatus of the present invention, when the unique data stored in the auxiliary ROM is set for each model, the control corresponding to each model is performed.
