Embodiment approach 1

[0012] figure 1 It is a perspective view of an electric vacuum cleaner equipped with the cyclone-type dust collector of Embodiment 1 of this invention. The electric vacuum cleaner main body 1 has an electric blower 6 and a cyclone dust collector 7 inside. In addition, a suction port 1a is formed in front of the electric vacuum cleaner body 1. A hose 2 is connected to the suction port 1a. A connecting pipe 3 is connected to the hose 2. An extension pipe 4 is connected to the connecting pipe 3. A suction member 5 is connected to the extension pipe 4. In this way, the hose 2, the connecting pipe 3, the extension pipe 4, and the suction tool 5 are sequentially connected from the suction port 1a of the electric vacuum cleaner main body 1, thereby constituting the electric vacuum cleaner 100. The electric blower 6 generates suction to suck in air. The suction force acts on the suction member 5 via the cyclone dust collector 7, the suction port 1a, the hose 2, the connecting pipe...

Abstract

A cyclone type dust collector apparatus includes a cylindrical filter 21 concentrically disposed in a cylindrical dust box (8, fig 2), a cylindrical dust accumulating space 52 disposed below the filter 21, an extending portion 22 formed to extend in an umbrella shape from a bottom portion of the filter 21 toward the dust accumulating space 52, a cyclone space 31 formed between an inner circumferential surface of the dust box and an outer circumferential surface of the filter 21. Further, the dust box has a slope portion 53 that widens conforming to the umbrella shape of the extending portion 22, and a dust collector path 32 is formed between an outer circumferential surface of the extending portion 22 and an inner circumferential surface of the slope portion 53 of the dust box. This structure produces a force that pushes the dust from the cyclone space 31 toward the dust accumulating space 52, preventing return of the dust accumulated in the dust accumulating space 52 back to the cyclone space 31, thereby improving the dust collection efficiency.

Description

Technical field [0001] The present invention relates to a cyclone type dust collection device and an electric vacuum cleaner having the cyclone type dust collection device. Background technique [0002] The cyclone-type electric vacuum cleaner includes an electric blower for sucking air, a suction part for sucking dust together with air, and a dust collecting device. The dust collecting device includes a cylindrical dust collecting part and a dust collecting chamber provided below the dust collecting part. The air sucked together with dust from the suction part rotates inside the dust collecting part. As a result, dust mixed in the air is separated due to the centrifugal force. The separated dust is captured and collected in the dust chamber. The dust-removed air is sucked by the electric blower. The dust captured and collected in the dust collection chamber is mainly flocculent dust. Therefore, dust may fly back to the suction part side. In order to prevent dust from retur...
