Stage: PROBLEM TO BE SOLVED: To provide a dust accumulation detection method and a dust accumulation detection device, each enabling removal of temporary influence due to external environment, and thereby enabling presence of dust accumulation to be accurately detected.SOLUTION: A dust accumulation detection device comprises: a light emission portion irradiating a prescribed portion of electric equipment with light; a light detection portion detecting light reflected from the prescribed portion or passed through the prescribed portion; a measurement terminal generating voltage according to current flowing in the light detection portion while the prescribed portion is irradiated with light from the light emission portion; a measurement portion measuring voltage of the measurement terminal; and a detection portion detecting accumulation of dust on the prescribed portion of the electric equipment. The measurement portion generates time series data by repeating measurement of the voltage for a prescribed period, the detection portion uses a movement center value calculated from the time series data to detect presence of the dust accumulation. Therefore, temporary affection due to external environments of the dust accumulation detection device can be removed, and presence of the dust accumulation can be detected accurately.SELECTED DRAWING: Figure 15 (Grant)
