The electric vacuum cleaner has a main body 1 containing a suction fan motor 2 and a motor driving means 3, a tip pipe 5 communicating with a hose 4, an extension pipe 6, and a floor nozzle 7, and the tip pipe 5 detects dust. As a means, a light emitting element 8 and a light receiving element 9 facing the light emitting element 8 are provided and connected to the control unit 10.

を吸い込みやすくする。In the above structure, the amount of light received by the light receiving element 9 and the generated voltage are in a proportional relationship as shown in FIG. 10, so that the amount of received light can be known by reading the voltage generated by the light receiving element 9. When the electric vacuum cleaner is driven, the fan motor 2 generates a suction force and dust is sucked in along with the air,
It passes through the tip pipe 5. When the dust crosses the light flux from the light emitting element 8, the amount of light received by the light receiving element 9 temporarily decreases, and a pulsed voltage is input from the light receiving element 9 to the control unit 10. When dust is detected by inputting a pulsed voltage,
The control unit 10 outputs a signal to the motor driving unit 3 to increase the input of the fan motor 2 to increase the suction force and make it easier to suck dust.

実施例と同様に素子の汚れに応じた処理を行う。In this structure, as shown in FIG. 6, the light receiving amount (generated voltage) of the light receiving element 9 temporarily decreases in a pulse shape when dust passes, but the high cut filter 25 is used.
Since the pulse-shaped signal is cut, the voltage generated by the light receiving element 9 after passing through the high-cut filter 25 becomes irrelevant to the passage of dust, and its change over time indicates a change in the amount of light due to the attachment of dust. As a result, the control unit performs the processing according to the dirt of the element as in the first embodiment.

It goes without saying that the voltage to be stored may be stored and the voltage after the passage of time may be compared with this to know the adhesion of dust to the element.
