On the other hand, when the input activation key SW2 is in the 'high' state, the heating operation is normally performed. When the input activation key SW2 is in the 'high' state, even when the time zone selection key SW1 is pressed, the time zone is This prevents misconfiguration of the heating regulator by young children.

If the state in which the input activation key SW2 of the time setting unit 20 is 'low' is maintained for a predetermined time, the microcomputer 90 determines that the state is to stop the heating operation and turns off the power of the heating control device. 'do. Of course, when the input activation key SW2 is 'on' while the power of the heating control device is 'off', the heating control device starts normal operation again to control the heating operation.

The temperature sensor 30 measures a current external temperature and provides the measured external temperature to the microcomputer 90.

The valve driver 60 controls the operation of the heating valve 100 to supply or cut off the heating hot water by opening or closing the heating hot water pipe.

To this end, the valve driver 60 may include a thyristor Q1 and a thyristor Q1 connected to the output terminal OUT5 of the microcomputer 90 to turn on / off the heating valve 100. It consists of resistors R8, R10, and R11 for driving transistor Q2.

When the transistor Q2 of the valve driver 60 is connected to the output terminal OUT5 of the microcomputer 90 and outputs an 'on' signal from the output terminal OUT5 of the microcomputer 90, the transistor Q2 is 'on'. The thyristor Q1 is 'off', and thus the heating valve is also 'off', thereby supplying heating hot water to the heating hot water pipe, thereby performing a heating operation to increase the indoor temperature.

On the other hand, when the 'off' signal is output from the output terminal OUT5 of the microcomputer 90, the transistor Q2 is 'off' and the thyristor Q1 is 'on', and thus the heating valve is 'on'. The execution of the heating operation is stopped by blocking the supply of the heating hot water to the heating hot water pipe.

The process in which the heating valve 100 is controlled by the state of the thyristor Q1 is as follows.

In the heating control device having a reservation function according to the present invention, as shown in FIG. 3, the first input INPUT1 of the AC power is input to the heating control device via the heating valve 100, and the second input INPUT2 is Is directly input to the heating regulator. That is, the heating valve 100 and the heating control device having a reservation function according to the present invention are connected in series, the valve drive unit 60 and the DC power generating unit of the heating control device having a reservation function according to the present invention ( 50 are connected in parallel.

When the thyristor Q1 of the valve driving unit 60 is 'off' by this circuit structure, the current of the AC power flows through the DC power generating unit 7 generating the DC current, and the heating valve 100 is By the amount of voltage consumed by the DC power generation unit 50, the heating valve 100 is not supplied with the current as much as possible to close the heating hot water pipe is 'off' state.

On the contrary, when the thyristor Q1 of the valve drive unit 60 is 'on', the operation of the thyristor Q1 is different depending on the direction in which the current flows, and the current flows from the first input INPUT1 to the second. When flowing in the direction of the input (INPUT2) current flows through the thyristor (Q1) of the valve drive unit 60 with a relatively low load resistance, the heating valve 100 is 'on' state to close the heating hot water pipe Receive as much current as possible.

On the other hand, when the current flows in the direction from the second input INPUT2 to the first input INPUT1 in the state where the thyristor Q1 of the valve driving unit 60 is 'on', it is reversed to the thyristor Q1 of the valve driving unit 60. The current flows through the DC power generating unit 50 generating the DC current, and the heating valve 100 is closed by the amount of voltage consumed by the DC power generating unit 50 so as to close the heating hot water pipe. Will not receive current.

That is, the heating valve 100 is continuously supplied with a current enough to be in the "on" state according to the flow direction of the alternating current in the state that the thyristor (Q1) of the valve drive unit 60 is 'on', As a result, the heating valve is slowly turned on.

The valve driving display unit 70 displays the driving state of the heating valve 100, that is, whether the heating operation is performed.

To this end, the valve drive indicator 70 includes an LED (LED5) connected to the output terminal (OUT5) of the microcomputer 90, and a resistor (R8) for applying a proper current to the LED (LED5), LED (LED5) ) Receives the 'on' signal from the output signal OUT5 of the microcomputer 90, the LED (LED5) is also 'on' and the LED is turned on, and when the LED (LED5) receives the 'off' signal This LED (LED5) is also 'off', which makes the LED light up.

The time pulse generator 80 outputs a pulse corresponding to the frequency (60 Hz) of the AC power flowing through the heating valve 100 to the input terminal IN8 of the microcomputer 90 so that the microcomputer 90 may calculate an accurate time. To help. To this end, the time pulse generator 80 is distributed with the resistors R15 and R16 and the capacitor C9 for distributing the current to output a pulse corresponding to 60 Hz having a current value of AC power appropriate to the microcomputer 90. The transistor Q3 outputs 60 Hz of the AC power supply to the input terminal IN8 of the microcomputer 90.

The microcomputer 90 includes a current time zone set by the user (IN6 to IN7), a temperature set by the user for each time zone (IN1 to IN4), and a time of 60 Hz provided by the time pulse generator 80 (IN8). And a program for controlling the operation of the heating device based on the measured external temperature (IN5) based on the input, and according to the result of this program, a signal for controlling the valve drive unit 60 and the time display unit 4 Output to the output terminal (OUT5). 5 is a flowchart illustrating a heating control method having a reservation function according to the present invention.

The heating controller sets the input activation key SW2 of the time setting unit 20 to 'low' state to select the current time zone corresponding to the current time, and then presses the time zone selection key SW1 to select the current time zone. Select the zone (step S1).

For example, if the time zone is set to the first time zone in the initial power state, if you want to change the time zone to the second time zone, set the input activation key (SW2) to 'low' and then select the time zone selection key ( Press SW1) once to change to the second time zone.

At this time, the time display unit 40 receives the 'on' signal of the output terminal OUT2 of the microcomputer 90 corresponding to the second time zone so that the connected LED is turned on so that the current time zone is the second time zone. Indicates that it is set.

When the current time zone setting is completed, the required temperature is set for each time zone by adjusting the resistance values of the variable resistors VR1 to VR4 of the temperature setting unit 10 corresponding to each time zone (step S2). .

An example of a temperature setting required for each time zone will be described with reference to FIG. 6.

Referring to Figure 6, the heating control device with a reservation function is divided into four time zones, each time zone zone from 3 AM to 8 AM, 8 AM to 5 PM, 5 PM to 8 PM , From 8 pm to 3 am.

15 ° C. at 3 am to 8 am, the first time zone, 10 ° C. to 8 am to 5 pm, the second time zone, and 20 ° C. to 5 pm to 8 pm, the third time zone. In the fourth time zone, 8 pm to 3 am, the heating temperature is set to perform heating to maintain 20 ° C.

   If the user wants to change the heating temperature, the user may adjust the resistance values of the variable resistors VR1 to VR4 of the temperature setting unit 10.

When the setting of the temperature for each time zone is completed, the heating device is operated by setting the input activation key SW1 of the time setting unit 20 to a 'high' state (step S3).

At this time, if the input activation key SW1 of the time setting unit 20 is set to a 'high' state, even if the time zone selection key SW1 of the time setting unit 20 is pressed, the set time zone is not changed.

When the current time zone setting and the setting of the temperature for each time zone are completed, the microcomputer 90 sets the microcomputer 90 to the temperature set by the resistance value of the variable resistor VR2 of the temperature setting unit 10 corresponding to the current time zone. The current temperature measured by the resistance value of the input terminal IN 2 of the terminal and the resistance of the thermistor TH1 of the temperature sensing unit 30 is input to the input terminal IN5 of the microcomputer 90, and the input temperature is input. And the measured current temperature are compared (step S4).

When the measured current temperature is higher than the set temperature corresponding to the current time zone as a result of the comparison of step S4, the microcomputer 90 outputs an 'off' signal to the output terminal OUT5 to stop the operation of the heating apparatus (step S5). ).

The LED (LED5) of the valve driving display unit 70 that receives the 'off' signal from the output terminal OUT5 of the microcomputer 90 is set to the 'off' state, and the transistor Q2 of the valve driving unit 60 is also ' The thyristor Q1 is 'on', and thus the heating valve 100 is also 'on' to stop the heating operation of the heating device (step S6).

When the thyristor Q1 of the valve driving unit 60 is 'on', when a current flows from the first input INPUT1 to the second input INPUT1, the current flows in the valve driving unit 60 having a relatively low load resistance. Through the thyristor (Q1) of the sufficient current to operate the heating valve 100 flows to the heating valve 100 is 'on'. When the heating valve 100 is 'on', the supply of heating hot water is cut off and the operation of the heating device is stopped.

When the measured current temperature is lower than the set temperature corresponding to the current time zone as a result of the comparison of step S4, the microcomputer 90 outputs an 'on' signal to the output terminal OUT5 of the microcomputer 90 to operate the heating device. (Step S7).

When the microcomputer 90 receives the 'on' signal from the output terminal OUT5, the LED (LED5) of the valve driving display unit 70 is set to the 'on' state so that the LED is turned on and the transistor of the valve driving unit 60 is turned on. Q2 is also 'on', the thyristor Q1 is 'off', and thus the heating valve 100 is also 'off' so that the heating operation of the heating device is performed (step S8).

When the thyristor Q1 of the valve driving unit 60 is 'off', the current passing through the heating valve 100 flows to the DC power generating unit 50 and consumes a large amount of current in the DC power generating unit 50 to heat it. The valve 100 is 'off' because it does not receive enough current to operate the heating valve 100. As a result, the heating valve 100 supplies the heating hot water to the heating hot water pipe, and the heating device performs an operation for heating.

The microcomputer 90 receives a pulse of 60 Hz from the time pulse generator 80, calculates an accurate time, and determines whether the time zone is changed (step S9).

As a result of the determination in step S9, when a predetermined time has elapsed and the time zone is to be changed, the microcomputer 90 changes and sets the current time zone to the next time zone, and the resistance of the variable resistor VR3 of the temperature setting unit 10 is changed. The temperature set by the value is received through the input terminal IN3 of the microcomputer 90 (step S10).
