Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[0032] figure 1 A perspective view showing the appearance of an electric vacuum cleaner according to an embodiment of the present invention, figure 2 It is an external perspective view showing a state where the dust collector 10 and the suction hose 2 are removed from the cleaner main body 1 . In addition, regarding the up-down direction, the left-right direction, and the front-rear direction, the figure 1 direction shown in . In addition, the left-right direction is the direction seen from the cleaner main body 1 side.

[0033] The electric vacuum cleaner S includes a vacuum cleaner main body 1 and a cyclone-type dust collector 10 detachably provided on the vacuum cleaner main body 1 .

[0034] The cleaner main body 1 is connected to a handle 3 via a suction hose 2 , and the handle 3 is connected to a suction nozzle body 7 for sucking dust...

Abstract

The present invention provides an electric vacuum cleaner and a dust collecting device thereof. Since the garbage is compressed inside the canopy, the dust collection amount of the garbage can be increased, and the return from the dust storage part to the dust separation part can be suppressed, and the dust separation performance can be improved. It suppresses the entanglement of hair to the suction part, etc., and since the garbage is compressed inside the canopy, it can suppress the flying of the garbage when the garbage is discharged, and the dust attached to the auxiliary filter (filter 2) can be discharged at the same time as the garbage disposal, so It is possible to provide an electric vacuum cleaner with good maintainability by reducing the work of cleaning the filter. In the dust collecting device of the electric vacuum cleaner of the present invention, the upper part of the inner tube is provided with a substantially cylindrical suction part having a first filter, and the lower part of the inner tube has an open umbrella part, and the suction part and the umbrella part pass through The second filter communicates, and the umbrella part has a sliding mechanism that protrudes in the direction of the opening when the bottom cover is opened.

Description

technical field [0001] The present invention relates to electric vacuum cleaners. Background technique [0002] In the prior art, there are roughly two types of dust collectors, namely: a paper bag type dust collector that compresses the attracted garbage in a paper bag; Cyclone dust collector inside. The cyclone method tends to increase the maintenance work of the dust collector compared with the paper bag method due to the swirling airflow generated. [0003] Japanese Patent Application Laid-Open No. 2007-167450 (Patent Document 1) describes the dust collection unit of an electric vacuum cleaner, which includes: a rotating chamber that separates the attracted dust from the suction wind by centrifugal force; A filter chamber for filtering by suction wind after the whirling chamber; and a dust chamber for accumulating separated dust. The filter chamber or the dust chamber side of the whirling chamber is formed into a substantially flat surface, and an auxiliary passage com...
