Electric vacuum cleaner

Abstract

To provide a small-size and easy-to-use vacuum cleaner having a cyclone separation type dust collection part. The cyclone separation cylinder 104 catching the dust by centrifugal separation and the dust collection case 105 having a first auxiliary filter 106 on the inside are detachably aligned and installed in a lower case 101 of a cleaner body 1. An inner cylinder 131 is composed of a cylinder part 134, a partition wall 132 spirally wound around the cylinder part 134 and a guide wall 137 connecting an inlet pipe 115 to the cylinder part 134. The exhaust of the cyclone separation cylinder 104 and the exhaust of the dust collection case 105 are joined together and pass in an electric blower. (C)2004,JPO&NCIPI.

Description

technical field [0001] The invention relates to an electric vacuum cleaner. Background technique [0002] A general electric vacuum cleaner introduces the dust-laden air sucked by the suction port into the vacuum cleaner body, removes dust through the dust collecting part in the vacuum cleaner body, and then discharges the clean air after dust removal to the outside of the vacuum cleaner body. The dust collection part is generally filtered by filter paper to capture dust for dust removal, or through centrifugal separation of cyclone separation cylinder to capture dust for dust removal. [0003] An electric vacuum cleaner equipped with a cyclone type dust collecting unit is described in Patent Document 1. The dust collecting part of this vacuum cleaner is constructed to capture and remove dust by centrifugal separation of one cyclone separation drum. [0004] In addition, as a cyclone-separation type dust collecting unit in an electric vacuum cleaner, the dust separation de...

AI Technical Summary

Problems solved by technology

[0006] The dust collection unit that captures dust with a single cyclone collects coarse dust and fine dust together, so when the captured dust is discarded, the fine dust is easily scattered, making the operation of discarding dust very troublesome

In addition, in order to improve the performance of capturing dust (dust collection = dust removal), the cyclone separator will be lengthened and the equipment will be enlarged.

[0007] The cyclone-type dust separator (dust collection unit) with the structure of the inner and outer double separation cylinders is difficult to form a compact and easy-to-operate form because the outer separation cylinder and the inner separation cylinder are combined into one structure.

In general household use, the operation frequency of capturing a large amount of coarse dust and discarding the coarse dust is very high, but the dust collection part with the structure of the inner and outer double separation cylinders cannot remove only the outer separation cylinder that has captured the coarse dust , only scrapping these coarse dust operations
