Problems solved by technology

Based on the above-mentioned structure, in the vacuum cleaner of the prior art, when the sucked air flows into the pipe, flow loss occurs due to friction.
As a result, the flow rate of air flowing into the dust separator will be reduced, and the suction force of the vacuum cleaner will be reduced.

Abstract

The present invention relates to a vacuum cleaner. The vacuum cleaner, according to one aspect, comprises: a cleaner main body which has a suction motor for generating suction force; and a suction hose which communicates with the cleaner main body and sucks in air and dust. The cleaner main body comprises: a main body part; a dust container which is provided to the main body part and has a suctionport through which dust sucked in through the suction hose is introduced, and a storage space in which the dust is collected; and a cover member which is provided with a connector having one side thereof connected with the suction hose, and which selectively shields at least one portion of the dust container, wherein, when the cover member shields one side of the dust container, the connector aligns in parallel with the direction in which air is introduced at the suction port.

Description

technical field [0001] The present invention relates to vacuum cleaners. Background technique [0002] Generally speaking, a vacuum cleaner is a device that uses a suction motor provided inside the main body to suck in dust and impurities that exist on the surface to be cleaned, and then filters the dust and impurities from the inside of the main body. [0003] The above-mentioned vacuum cleaners can be divided into: an upright (up-right) vacuum cleaner in which the suction nozzle is connected to the body and moves together with the body, and a horizontal (up-right) vacuum cleaner in which the suction nozzle is connected to the body through extension pipes, handles, hoses, etc. canister) type vacuum cleaner. [0004] Korean Laid-Open Patent Publication No. 10-2012-0004100 (publication date: January 12, 2012), which is a prior document, discloses a canister vacuum cleaner. [0005] The vacuum cleaner of the prior art disclosed in said prior document includes: a suction moto...
