Problems solved by technology

[0003] However, the dust separated by the cyclone dust collecting part after the conventional dust collection is affected by the swirling airflow in the cyclone dust collecting part and accumulates in the electric vacuum cleaner below the dust collecting part. Dust floats up and clogs the filter surface, so there is a problem of low suction power
[0004] In addition, due to the natural accumulation of dust under the influence of the swirling airflow in the swirl dust collection part, it is difficult to form a compact state in the dust collection chamber, and it is necessary to frequently collect dust to form a full state with less than the capacity of the dust collection chamber. expel dust

Abstract

A dust collection box of the invention is composed of a separation part, a dust collection part which collects the dust separated in the separation part, and a bottom cover which covers the lower opening of the dust collection part, wherein, the separation part is provided with a swirling chamber which is configured to the upstream side of an electric air blower which generates the sucked air current and is composed of a filtering net that is provided with a plurality of small through holes, and a crease type filter which covers the periphery. Through the suction of a communication hole whichis formed between the lower part of a separation wall of the dust collection part and the bottom cover, the floating of the dust which is caught in a first dust collection chamber in the swirling chamber can be prevented, and the dust suction force can be sustained.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner having a structure of a cyclone dust collecting unit that rotates sucking in air to separate and accumulate dust by centrifugal force, and has a detachable dust box. Background technique [0002] In conventional electric vacuum cleaners having a cyclone dust collecting part, generally, the dust separated by the cyclone dust collecting part after dust collection is affected by the swirling airflow in the cyclone dust collecting part and accumulates under the dust collecting part. side (for example, refer to Patent Document 1). [0003] However, the dust separated by the cyclone dust collecting part after the conventional dust collection is affected by the swirling airflow in the cyclone dust collecting part and accumulates in the electric vacuum cleaner below the dust collecting part. Dust floats up and clogs the filter surface, resulting in a problem of low suction power. [0004] In additio...
