- In particular, a cyclone-type vacuum cleaner configured to separate dirt from the air using a centrifugal force is semi-permanent, and is more sanitary and convenient than a vacuum cleaner using a dust bag or a dust filter, and the the cyclone-type vacuum cleaner is widely used.
- In recent years, a multi-cyclone dust separating apparatus for filtering out dirt through more than two stages using a plurality of cyclones connected in a series has been developed for use. Such a multi-cyclone dust separating apparatus includes a first cyclone part configured to separate a large-size dirt and a second cyclone part configured to a small-size dirt, thereby effectively removing dirt.
- Examples of the vacuum cleaner are disclosed in the US patent application publications U.S. Pat. No. 7,547,351 B2, US 2007/0214754 A1 and U.S. Pat. No. 7,966,692 B2. A dust-selecting apparatus of the vacuum cleaner disclosed in the above publications has a first clone part disposed at the center of a cylindrical case and a plurality of second cyclone parts disposed around the first cyclone part. A first dust collecting compartment configured to collect dust filtered out by the first cyclone part is disposed adjacent to a circumference of an inner space of the case.
- In addition, the dust-separating apparatus is provided on a vacuum cleaner body so as to be detachable in a horizontal direction, and an upper surface or a lower surface of the dust separating apparatus, which is open to discard the collected dirt, is open and closed by a cover.
- Therefore, it is an aspect of the present disclosure to provide a vacuum cleaner having a superior stability by lowering the center of gravity, and having an improved aesthetic quality.
- It is another aspect of the present disclosure to provide a vacuum cleaner having a dust-collecting compartment enlarged without increasing the height of the vacuum cleaner, and the vacuum cleaner having the same.
- It is another aspect of the present disclosure to provide a vacuum cleaner having a dust-separating apparatus configured to be vertically detachable with respect to a vacuum cleaner body.
- It is another aspect of the present disclosure to provide a dust-separating apparatus enabling a cover of the dust-separating apparatus to be easily detachable when dirt collected in a dust-collecting compartment is discarded.
- Additional aspects of the disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the disclosure.
- In accordance with one aspect of the present disclosure, a vacuum cleaner includes a first cyclone part and a second cyclone part that form a whirl flow approximately in a horizontal direction A first dust collecting compartment is formed at a lower side of the first cyclone part and the second cyclone part.
- In addition, the vacuum cleaner may include a dust-separating apparatus accommodation part having an upper surface open. A dust-separating apparatus may be provided to be detachable with respect to the dust-separating accommodation part in an approximate vertical direction.
- In addition, a grip of the dust separating apparatus may be provided at an upper side of the dust separating apparatus, and include a grip body, which is fixed to an upper surface of the dust separating apparatus, and a grip lever, which is movably coupled to the grip body and has a protrusion elastically biased while being insertedly fixed to a body of a dust separating apparatus.
- In addition, the vacuum cleaner may include a front cover and a rear cover, which are detachably coupled to the body of the dust separating apparatus, and a button. The button may include a locking protrusion that protrudes upward and a pressing part provided to be exposed through a grip groove of the front cover. The button may be elastically biased such that the locking protrusion is insertedly fixed to a groove of the dust separating apparatus.
- According to the embodiments of the present disclosure, the center of gravity of the vacuum cleaner is lowered, so the stability is enhanced while improving the aesthetic quality of the vacuum cleaner.
- In addition, the size of the dust-collecting compartment is expanded without increasing the height of the vacuum cleaner and thus the period in emptying the dust-collecting compartment is prolonged.
