る。Embodiment The figure shows one embodiment of the present invention, in which 1 is an air filter provided in a wind passage, and 2 and 3 are a fan and a motor. 4 is a power switch, and 5 is a commercial power source. The commercial power source 5 is rectified by a diode 6 to create a DC power source 7. 8
is a microcomputer, which includes a collar 1-9 for measuring the energization time of the motor 3, a presetting means 10 for presetting the reading counter when the power is turned on, and a counter 9.
The comparison means 11 outputs when the value of becomes equal to or greater than a predetermined value,
Processed by the program of the microcomputer 8. The counter 9 counts pulses synchronized with the commercial power supply 5 and measures the energization time of the motor 3. Reference numeral 12 denotes a non-volatile memory that stores and recognizes the counter value when the power switch 4 is turned off. 13 is an output information means from the comparison means 11;
14 is a light emitting diode. Next, the operation will be explained.

９の値を不揮発性メモリー１２に書き込む。When the power switch 4 is closed, the motor 3 is energized and at the same time a DC power source 7 is formed. Then, the microcomputer 8 starts operating. Counter 9 is commercial power supply 6
The pulses synchronized with are counted, and the energization time to the motor 3 is measured. The count value is constantly compared with a predetermined value by comparison means 11. Here, when the power switch 4 is opened, the commercial power signal to the counter 9 disappears, so the microcomputer 8 knows that the switch 4 is open, and the counter 9 is output in a short period of time until the DC power supply 7 disappears. The value of is written to the non-volatile memory 12.

Therefore, the energization time to the motor 3 is added to the previous energization time. By repeating this operation, the comparison means 11 compares the total energization time to the motor 3 (counter value) with a predetermined value.
When the total sum becomes larger, the signal is output, the notification means 13 is driven, and the light emitting diode 14 is turned on.

の応用が簡単にでき、実用的にきわめて有用である。Effects of the Invention As described above, according to the present invention, the time to clean (or replace) the filter is notified based on the total amount of current applied to the motor, so it can be realized entirely by electronic circuits, and the installation location is limited. It also requires less assembly time. Furthermore, the present invention is easily applicable not only to dryers but also to devices having air filters, such as air cleaners, air conditioners, humidifiers, etc., and is extremely useful in practice.
