ある。 FIG. 1 shows an electric circuit diagram of a conventional vehicle air conditioner and an indoor fan. In FIG. 1, the control power switch 1 and the air conditioner power switch 6 are turned on,
When any one of the blower command switch 3, weak cooling command switch 4, and strong cooling command switch 5 is turned on, the electromagnetic contactors 7, 8, and 9 are excited in response to each command, and the air conditioner 13 is activated in accordance with the command. to air condition the inside of the car. Next, when the indoor fan power switch 11 is turned on and the indoor fan command switch 2 is turned on, the indoor fan 12 is excited and starts operating. Here, this indoor fan 1
2 is most effective when the heat load inside the vehicle exceeds the capacity of the air conditioner, that is, during rush hours. This is used when the car is crowded with passengers and the cold air cannot reach the lower part of the car, and is based on the idea of cold air air conditioning, which blows cold air directly onto the passengers to make them feel cooler. .

状態が起き易いという欠点もあつた。 However, although the use of this indoor fan 12 has the above-mentioned effect when the inside of the car is crowded, the indoor fan is operated during quiet times during the day and during quiet times at night, causing excessive cooling. It had the disadvantage of being Furthermore, since the indoor fan 12 is operated at the discretion of the crew, it cannot necessarily be said that it is handled appropriately. It also had the disadvantage that it was easy to get into trouble.
本発明の目的とするところは、室内フアンと空

である。 The present invention detects the temperature inside the car every predetermined period of time, compares the detected inside temperature value with the set value of the inside temperature, and determines that the detected inside temperature value is higher than the set value of the inside temperature.
Furthermore, the present invention is characterized in that at least two successive detected values of the temperature inside the vehicle are compared, and the indoor fan is operated when the temperature inside the vehicle tends to rise.
以下、本発明を実施例等を用いて説明する。空

で、この時は室内フアンを運転する必要はない。 Hereinafter, the present invention will be explained using examples and the like. The operating time when the air conditioner is in operation, the heat load on the vehicle body, and the temperature inside the vehicle at that time are as shown in FIG. In other words, when the heat load on the car body is smaller than the cooling capacity of the air conditioner, the temperature inside the car is kept constant by the action of the temperature controller installed in the air conditioner, so the indoor fan is not operated at this time. do not have to.

にすることができる。 Next, the heat load on the car body exceeds the cooling capacity.
Furthermore, if the temperature inside the vehicle exceeds a certain set value, the temperature inside the vehicle will rise due to insufficient cooling capacity, as shown in FIG. In this case, passengers experience the phenomenon of "not getting cold." To eliminate this phenomenon, operating an indoor fan can increase the feeling of cooling, thereby achieving an appropriate cooling state.

車内温度の判定に戻る。 In the figure, the temperature inside the vehicle is detected by a temperature detector 18, and the signal of the detected temperature inside the vehicle is amplified to a signal of a predetermined magnitude and then input to the input/output circuit 15. Here, the signal of the vehicle interior temperature detection value is converted from an analog signal to a digital signal, and the CPU 1
Enter 4. Based on a program stored in the ROM 16, the CPU 14 stores the detected vehicle interior temperature value in the RAM 17 as data every predetermined period of time. First, a comparison is made between the currently detected vehicle interior temperature value and the aforementioned set value. As a result of this comparison, if the detected value of the temperature inside the vehicle is lower than the set value, the next detected value of the temperature inside the vehicle is determined.
On the other hand, if the detected temperature inside the vehicle is higher than the set value, the following calculation is performed, that is, the detected temperature inside the vehicle one time before the current detected temperature inside the vehicle is compared with the current detected temperature inside the vehicle. Determine whether the temperature is on the rise. As a result, when the temperature inside the vehicle tends to rise, an operation control command for exciting the auxiliary relay 19 and operating the indoor fan 12 via the input/output circuit 15 is output. In addition, if the temperature inside the car is constant or decreasing, after a certain period of time,
Return to determining the temperature inside the car.

でき、常時適切な空気調和が行なえる。 According to the above-mentioned operating conditions, when the heat load of the vehicle body increases exceeding the cooling capacity and the temperature inside the vehicle becomes higher than the temperature setting value inside the vehicle, the indoor fan 12 is operated to cool the air inside the vehicle. It can stir and provide a cooling sensation to passengers. That is, the indoor fan 12 can be appropriately controlled in response to changes in the operating state of the air conditioner, that is, the cooling capacity and the heat load of the vehicle body, and appropriate air conditioning can be performed at all times.
