Abstract

The invention relates to a cleaning device for an extractor hood fan system. The cleaning device is located on the outer side of an extractor hood fan, the fan comprises a volute with an air outlet and an impeller disposed in the volute, and the cleaning device includes a nozzle. The cleaning device is characterized by further comprising a first driving mechanism; the volute is provided with an opening; and an outlet of the nozzle faces to the opening and moves in the length direction of the opening under the drive of the first driving mechanism. Compared with the prior art, the cleaning device has the advantages that the impeller can be completely cleaned and the cleaning effect can be improved; in addition, the cleaning device is provided with a shielding part which shields the opening,and the shielding part can open and close the opening under the drive of a second driving mechanism; in a cleaning state, the opening is opened, the nozzle faces to the opening to achieve the cleaningof the impeller; and in a non-cleaning state, the opening is closed to prevent airflow in the fan from causing disturbance and generating noise.
