Abstract

The invention provides a range hood. The range hood comprises a box body and a fan system arranged in the box body, wherein the fan system comprises an air inlet ring and an impeller device, wherein the air inlet ring is arranged at an air inlet of the impeller device; a through hole is arranged in the air inlet ring; the impeller device comprises an impeller rim; a distance measuring module is arranged at the inner side of the box body; the distance measuring module faces the through hole; and the distance measuring module measures the distance between the distance measuring module and the impeller rim through the through hole. When the impeller device operates, the distance measuring module measures the distance between the distance measuring module and the impeller rim in real time in order to detect the variation of the axial displacement of the impeller device, and whether the impeller device operates abnormally or not is detected by judging whether the variation of the axial displacement of the impeller device exceeds a preset threshold value or not.
