摘要:
Disclosed is a dust-collecting apparatus with a packing member. The disclosed dust-collecting apparatus for separating dust from introduced air comprises: a dust-collecting receptacle with an open bottom; a dust discharge cover arranged at the bottom of the dust-collecting receptacle such that that the dust discharge cover can be opened/closed; and a packing member for sealing the dust-collecting receptacle and the dust discharge cover, wherein the packing member presses the dust discharge cover in the direction of opening the dust discharge cover. Thus, the dust discharge cover can be opened from the bottom of the dust-collecting receptacle in an easier manner.
