DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a petroleum fan heater having a vaporizer for vaporizing liquid fuel by an electric heater and preheating the vaporizer in an off mode will be described below with reference to the drawings.

FIG. 2 shows a liquid fuel combustion device used for an oil fan heater. In FIG. 2, reference numeral 1 denotes a burner motor. A rotary atomizer 3 for atomizing kerosene is provided at one end of a rotary shaft 2 and a burner fan 4 for supplying combustion air is provided at the other end. 5 is a rotating atomized body 3

Reference numeral 11 denotes a heat recovery ring provided on the outer periphery of the burner head 9 so as to face the flame port 10 and is formed integrally with the vaporizer 5. Reference numeral 12 denotes an electromagnetic pump for supplying oil supplied from a cartridge tank to an oil pan (not shown) to the rotary atomizer 3 via a fuel supply pipe 13; 14 a temperature sensor for detecting the temperature of the vaporizer 5; Is a control device, 16 is an ignition device,
F is a blower fan.

FIG. 3 shows a basic configuration of the control device 15 described above. In FIG. 3, reference numeral 18 denotes a microcomputer (hereinafter referred to as a microcomputer) which has a clock function and includes an A / D converter and a nonvolatile memory (EEPROM). A preheat switch 20, a timer switch 21, a temperature setting device 22, a temperature sensor 14, and a room temperature sensor 23 are provided. On the output side of the microcomputer 18, the electric heater 7, the ignition device 16, the burner motor 1, the electromagnetic pump 1
2 and a blower fan F are provided.

As shown in FIG. 1, the microcomputer 18 has control data generating means 24 for energizing the electric heater 7 when the operation switch 19 is off and the preheating switch 20 is on, and a heater control means. 25 are provided. The control data generation means 24 includes three input layers I1 to I3, four intermediate layers H1 to H4, two output layers S1 and S2, teacher data generation means 26, and teacher data from the teacher data generation means 26. Output layers S1 and S2
Error correction means 27 for comparing the control data of the first and second control data and updating the coupling coefficient between the output layer and the intermediate layer and between the intermediate layer and the input layer according to the error between the teacher data and the control data. It has a net configuration.

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 input layer I2 is connected to a time difference signal generating means 29 for generating the closest deviation time between the present time and the combustion time zone of the previous day as a count value in units of 10 minutes. Of course, 0 is input to the input layer I2 when burning at the same time of the previous day. This time difference input is the most important factor in determining the heater control temperature and the necessity of energizing the heater described later.

In the input layer I3, the minimum room temperature of the previous day was 0.2 ° C.
A temperature signal generating means 30 for generating a digital signal for the step is connected. This temperature signal generating means 30
Among the days (0:00 to 24:00), the lowest room temperature among the room temperatures detected by the room temperature sensor 23 is stored, and the next day is transmitted as a temperature signal. This minimum room temperature input is effective in judging the seasonal use time zone.

The data input to the input layers I1 to I3 in this way is adjusted by the coupling coefficient and then transmitted to the intermediate layers H1 to H4. Intermediate layers H1 to H4
Calculates the sum of the inputs from the input layers I1 to I3,
The output is calculated (eg, a Sigmond function) based on the sum of these inputs. The outputs of the intermediate layers H1 to H4 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 includes one performed by the manufacturer in advance (factory learning) and one performed by the user on site (on-site learning). Factory learning means that the above-mentioned data of the current time, the time difference, and the lowest room temperature and the control data (teacher data) preferable to the above are repeatedly inputted to the microcomputer 18 and, for example, control data suitable for a standard home use time zone. Is generated. FIG. 4 shows one example, in which the levels of Toff and Ton are reduced from 0:00 am to 5:00 am to save energy.

On the other hand, the on-site learning means that the user inputs data of the combustion time zone designated by the operation switch 19 or the timer switch 21 and the actual lowest room temperature, obtains ideal teacher data in the microcomputer 18, and In this embodiment, both factory learning and on-site learning are performed. When these are used together, To
The control levels of ff and Ton are as shown in FIG. 5, for example.

Here, the learning rates of the factory learning and the on-site learning are set so that the former is sufficiently larger than the latter (for example, 70% or more).
In addition, it is preferable that factory learning be sufficiently performed so that the learning result of the on-site learning always converges to the minimum value.

That is, if the learning rate of the factory learning is set to be sufficiently higher than the learning rate of the on-site learning, the preheating control characteristic can be prevented from largely fluctuating due to the temporary use state of the equipment. The user does not have to worry about the fluctuations. In addition, the back propagation method is used for learning the neural network described above. However, the back propagation method is slow in convergence, and may not converge to a minimum value but converge to a minimum value (local minimum). There is. Therefore, by fully performing factory learning, on-site learning is always minimized,
And it can be made to converge in a short time.

According to the present embodiment, when the operation switch 19 is off and the preheating switch 20 is on, the heater control means 25 controls the control data (To
ff and Ton) are compared with the temperature detected by the temperature sensor 14, and the energization of the electric heater 7 is controlled so that the temperature of the vaporizer 5 is maintained between Toff and Ton. Since the control data is determined by learning the actual use time period of the user, it is possible to minimize the amount of electricity supplied to the electric heater 7 while turning on the operation switch 19 so that gasification combustion is performed immediately. it can. And at this time, for example, midwinter
In early spring, the room temperature, which is the usage environment of the equipment, is different.
The preheating time by the heater 7 also differs. Usage environment and season

If the pre-heating preparation operation is performed for the burn
Heater 7 is turned on, and in the early spring, the electric heater 7 is turned on with a slight delay.
For example , the heater control temperature is determined while determining the time and season. In this way, in the early spring , power consumption can be reduced compared to the severe winter season, and the energy saving effect is further improved . In addition, all systems are controlled only by local learning data.
When the control data is determined,
The time and temperature for thermal control also depend on the season in which the equipment has been used.
Te changes, control characteristics or vary greatly in the preparation operation for on-mode of the device, a possibility that the field learning to become unstable
However, in the present invention, the control data generating means 24

The instability of the operation switch can be prevented, and the preheating control while the operation switch is off can be appropriately performed according to the usage condition of the device.

It should be noted that the heater control means 25 may be provided with a judging function so that when Toff and Ton are equal to or less than a predetermined value, it is determined that energization of the heater is unnecessary and the energization of the electric heater 7 is stopped. In this way, for example, as shown in FIG. 6, power is further saved.

As shown in FIG. 7, the control data generating means 24 is provided with an output layer S3.
, It may be possible to generate data on the necessity (ON / OFF) of heater energization, or generate data only on necessity of heater energization.

Further, the above-mentioned control data generating means 24

While only the preheating switch 20 is turned on, the energization of the electric heater 7 may be controlled at all times, or a dedicated switch using only control data based on factory learning may be provided.

In addition to the above-described combustion equipment such as the oil fan heater, the present invention operates the compressor at a low rotation speed while the operation is stopped, or preheats the refrigerant with an electric heater so that the hot air is simultaneously generated at the start of the operation. The present invention can be similarly applied to an air conditioner that can emit light, and a television device in which a CRT is preheated in an off mode so that an image can be viewed when the switch is turned on.
