Abstract
A blower includes a fan, an inlet through which air is drawn into the fan, and an outlet through which an air flow from the fan is exhausted. The inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter. The relationship A <C, A <B is satisfied, where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a minimum particle size of dust that would compromise the dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet. The blowing performance can be improved within the range of dust-proof performance in which damage or functional degradation can be avoided.
