In the conventional example as described above, when the heater starts operating, the performance of the heater and the indoor environment are learned, and the automatic operation start time by the timer setting means is corrected. Among the calculations for this correction, it is not clear how to learn the indoor environment.

FIGS. 2 and 3 show a block diagram and a detailed diagram of the neural network constructed by the software of the microcomputer 5. The previous room temperature detected by the room temperature detection means and the previous set temperature set by the temperature setting means are shown in FIGS. , based on the current set temperature, the previous temperature difference, the current temperature difference, and the arrival time by a timer that measures the time from the start of operation until the room temperature reaches the set temperature are input to the input layer consisting of neuro elements. The output of the input layer is input to the input of the intermediate layer consisting of neuro elements, and the intermediate output is calculated as the difference between the timer setting time set by the timer time setting means and the time at which the operation is started before the timer setting time. The timer advance time is inputted by the output of the intermediate layer, and outputted from the output layer consisting of neuro elements, and a neural network is constructed from the input layer, the intermediate layer, and the output layer by the software of the microcomputer 5. Note that the previous time is before the timer time set last time.
This refers to the time before the start of operation, and the current time refers to the time before the timer time set this time and before the start of operation. This neural network is first trained on representative data. The weight and threshold value of each neuro element are sequentially determined.

FIG. 4 shows microcomputer software mainly related to timer operation. When operating with a timer, it is necessary to detect the room temperature before the timer advance time, so this time is called the maximum timer advance time (approximately 45 to 90 minutes before the set time), and this time is stored inside the microcomputer 5. Set it in advance.

[0021] In the case of timer operation, step S3
When the timer operation switch 16-3 is pressed at , the clock display is switched to the timer operation time display for a certain period of time. That is,
AM LED17-2, PM LED17-3, numeric LED
17-1 switches to a numeric display of the timer operation time, and the timer operation LED 17-9 continues to light up. Step S4
At this time, the microcomputer 5 continues to wait for the timer until a time that is the maximum timer advance time before the timer operation time. In step S5, when the maximum timer advance time is reached,
The room temperature at that time is detected by the thermistor 14. In step S6, the microcomputer 5 calculates the temperature difference. Proceed to step S7. Input the memorized temperature difference and arrival time from the previous timer operation and the temperature difference found this time into a neural network, process it in the neural network using, for example, a back propagation method, and calculate the timer advance time from the output of the neural network. demand.

[0022] In step S8, the timer wait continues until before the timer advance time. When the timer reaches the advance time, the microcomputer 5 lights up the operation LED 17-5, the display section 17 switches from the clock display to the temperature display, and the AM LED
17-2, afternoon LED 17-3, colon is extinguished, temperature L
The ED lights up. Also, the output ports 5-8, 5 of the microcomputer 5
-6 and 5-7, the igniter 4, pump 2, and convection fan motor 3 are operated to start the operation of the heating means 2 (step S9). Proceeding to step S10, the arrival time relaxation is determined.

There is a neural network inside the microcomputer 5, which stores the previous day's (previous) state and feeds it back to the next day's (current) operation to reach the desired temperature (set temperature) at the timer operation time. That is, a specific indoor environment can be determined using a neural network.

[0024]

[Effects of the Invention] According to the present invention, processing is performed using a neural network that inputs the previous temperature difference, arrival time, and current temperature difference and outputs the timer advance time, so it is possible to specifically determine the indoor environment. Can be done. In other words, the state of heat load can be determined. Then, the desired temperature is reached at the timer operation time. A specific indoor environment is required. Since it uses a neural network, there is no need to separate the input, and continuous input and continuous output are possible. Therefore, control becomes smooth.

Although the neural network processing of the present invention has been explained using the backpropagation method, other methods may be used. Further, although the room temperature detection timing has been explained before the maximum timer advance time, the same or better effect can be obtained even before the timer advance time.
