FIG. 6 shows another embodiment using the control data generating means 24 having a neural network configuration.
In FIG. 6, the control data generating means 24 includes four input layers I1 to I4, five intermediate layers H1 to H5,
Output layers S1 and S2 and teacher data generating means 26
Is compared with the control data of the output layers S1 and S2, and the connection between the output layer and the intermediate layer and the connection between the intermediate layer and the input layer is performed according to the error between the teacher data and the control data. Error correction means 2 for updating coefficients
7 and has a neural network configuration having a learning function.

A 24-hour timer 28 is connected to the input layer I1. This 24-hour timer 28 operates at time 0: 0.
The initial value becomes 0, and a count signal is added by one every 10 minutes thereafter, and the present time is input to the input layer I1. For example, at time 6:00, 36 is input from the 24-hour timer 28 to the input layer I1. This current time input is for absorbing a difference in usage frequency between the morning and afternoon time zones.

The time difference signal generating means 29 is connected to the input layer I2. This time difference signal generating means 29 is the last five oil fan heaters stored in the data storage device RAM.
The average value of the minimum value for each day of the deviation time between the usage time data of the day (newest priority) and the current time data of the 24-hour timer 28 is obtained. This average time difference signal is counted in units of 10 minutes. (For example, 0 to 125) to the input layer I2. This time difference input is the most important factor in determining the heater control temperature and the necessity of energizing the heater described later. For example, when the minimum value of the time difference data for the past five days is 24, 18, 18, 24, 30, the average value is 22.8, and is rounded to 23. Then, 23 (corresponding to 3 hours and 50 minutes) is input to the input layer I2 as time data.

The input layer I3 is connected to a temperature signal generating means 30 for generating a digital signal of the lowest room temperature of the previous day stored in the data storage device RAM as a digital signal in steps of 0.2 ° C. This temperature signal generating means 30 operates for one day (0: 00-2).
4:00), the lowest one of the room temperatures detected by the room temperature sensor 23 is stored, and this is emitted as a temperature signal the next day. This minimum room temperature input is effective in judging the seasonal use time zone. Further, the above-mentioned ignition number recording means DM is connected to the input layer I4,
The ignition count data in the time zone corresponding to the current time is input.

The data input to the input layers I1 to I4 is adjusted by the coupling coefficient and transmitted to the intermediate layers H1 to H5. Intermediate layers H1 to H5
Calculates the sum of the inputs from the input layers I1 to I4,
An output is calculated (for example, a Sigmond function) based on the sum of these inputs. The outputs of the intermediate layers H1 to H5 are transmitted to output layers S1 and S2 after being adjusted by the coupling coefficient. In the output layers S1 and S2, the sum of all inputs is obtained, and the output is calculated (for example, a Sigmond function) based on the sum of these inputs, and output as the heater off level Toff and the heater on level Ton, respectively.

The learning of the control data generating means 24 is performed in a factory or in the field. Factory learning means that the above-mentioned data of the current time, the time difference, the minimum room temperature and the number of times of ignition (frequency of use) and the teacher data preferable for this are repeatedly input to the microcomputer 18 and suitable for, for example, a standard home use time zone. To generate control data. FIG. 7 shows an example of this, in which the levels of Toff and Ton are reduced from midnight to 5:00 am, which is less frequently used, to save energy.

On the other hand, the on-site learning means that the user inputs data such as the combustion time zone specified by the operation switch 19 and the timer switch 21, the actual minimum room temperature, and the number of ignitions (frequency of use). In this embodiment, learning is performed in accordance with actual use conditions. In this embodiment, both factory learning and on-site learning are performed.

In this embodiment, data of the current time, the current time, the time difference, the minimum room temperature and the number of ignitions are repeatedly inputted, and learning is performed by comparing the control data obtained as a result with the teacher data. Even when the usage time data is present, when the usage frequency is low, learning is performed so that the control data becomes small, and the power consumption can be suppressed by maintaining the temperature of the vaporizer 5 at a relatively low temperature. On the other hand, even in a time zone where there is no use time data, if the frequency of use is high, learning is performed so that the control data becomes large,
The temperature of the carburetor 5 can be maintained at a relatively high temperature to prepare for the combustion operation in the ON mode. In this way,
When factory learning and on-site learning are used together, Toff and Ton
Is as shown in FIG. 8, for example.

When the operation switch 19 is off and the preheating switch 20 is on, the heater control means 25 compares the control data (Toff and Ton) from the control data generation means 24 with the temperature detected by the temperature sensor 14 and evaporates. The energization of the electric heater 7 is controlled so that the temperature of the heater 5 is maintained between Toff and Ton. Since the control data is determined by learning the actual use time zone of the user, the operation switch 1
The gasification combustion can be carried out promptly at the time of charging 9 and the amount of electricity supplied to the electric heater 7 can be minimized. In addition, since the heater control temperature is determined while judging the time and the season, the power consumption is different between the early spring and the severe winter, and the energy saving effect is further improved.

The heater control means 25 is provided with a judging function. When Toff and Ton are equal to or less than a predetermined value, it is judged that heater energization is unnecessary, and energization of the electric heater 7 is stopped.

FIG. 9 shows another embodiment using the control data generating means 24 having a neural network configuration.
In FIG. 9, the control data generating means 24 includes three input layers I1 to I3, four intermediate layers H1 to H4,
Output layers S1 and S2 and teacher data generating means 26
Is compared with the control data of the output layers S1 and S2, and the connection between the output layer and the intermediate layer and the connection between the intermediate layer and the input layer is performed according to the error between the teacher data and the control data. Error correction means 2 for updating coefficients
7 and has a neural network configuration having a learning function.

In this embodiment, instead of inputting the ignition frequency (use frequency) data of the ignition frequency recording means DM to the input layer I4 , the teacher data generation means 26 has the ignition frequency recording means D
The teacher data is generated in accordance with the ignition count data of M. In this embodiment, too, the higher the frequency of use, the larger the control data is learned. such as control data is reduced learning is performed while to not adversely utmost impair the usability of the user can reduce the power consumption of the electric heater 7.

The present invention can be applied as a control device for a device that controls the operation based on control data, such as an air conditioner, in addition to the above-described hot air heater such as an oil fan heater.
