Definitions
- the present invention relates to a vacuum cleaner for separating and collecting foreign matter, dust and fine dust using a multi-cyclone.
- a vacuum cleaner sucks in air using a suction force, filters and collects foreign matter, dust and fine dust contained in the air, and discharges clean air back to the outside.
- the types of vacuum cleaners can be classified into 1) canister type, 2) upright type, 3) hand type, and 4) cylindrical type floor type.
- the vacuum cleaner of the canister type is the most widely used vacuum cleaner in the household today, and the vacuum cleaner has a structure in which the suction unit and the cleaner body are separated from each other.
- the vacuum cleaner of the canister type is suitable for cleaning the floor, since the suction unit does not have the rotary brush and performs the cleaning only by suction of the air through the suction unit.
- the upright type vacuum cleaner is a vacuum cleaner having a structure in which a suction unit is integrally formed in the cleaner main body.
- the upright type vacuum cleaner includes the rotary brush, unlike the vacuum cleaner of the canister type, dust and the like in the carpet can be cleanly cleaned.
- a cyclone separator has been used to separate particles such as dust from the air stream of a vacuum cleaner.
- two cyclone devices are known in which the airflow is arranged to pass through at least two cyclones continuously.
- the first cyclone of the two cyclones separates larger dust and foreign matter from the airflow by the filter and the second cyclone is configured to separate relatively small dust (fine dust) from the airflow passing through the first cyclone.
- a tapered skirt is also provided. Since the portion where the skirt is formed forms a small gap with the outer case, a phenomenon that a large foreign object or dust is caught in the gap may occur. When foreign matter is trapped in the gap, other foreign matter and dust are prevented from flowing into the first storing portion through the gap.
