Description

A cyclone dust-collecting apparatus of vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a cyclone dust collector of a vacuum cleaner that collects and collects dirt contained in air sucked from the outside.

In general, a vacuum cleaner equipped with a cyclone dust collector, referring to FIG. 1, connects the cleaning main body 10, the suction brush 13 for sucking dirt, and the suction brush 13 to the cleaning main body 10. It consists of a suction extension pipe (17) and a dust collecting hose (14). And the suction extension pipe is equipped with a cyclone dust collector (15). As shown in FIG. 2, the cyclone dust collector 15 includes an air inlet 15a and an air outlet 15b, and a cyclone cover 19b having a grill 15c having fine dust passage holes formed therein. ) And a cyclone dust collector (19a).

The vacuum cleaner configured as described above is supplied with power to the suction motor 11 by the operation of the switch unit provided in the handle 16, and the suction motor 11 is driven to generate suction power. As the suction force is generated, the suction brush 13 sucks the air containing the dirt through an inlet (not shown) formed on the lower surface, and the sucked air is centrifuged through the cyclone dust collector 15 to first discharge the dirt. The dust, which is not filtered by the cyclone dust collector 15 such as fine dust, is collected in the dust collecting bag 12 of the dust collecting chamber 10a provided inside the cleaner 10.

By the way, in the vacuum cleaner having such a configuration, large dusts are accumulated in the cyclone dust collector 15, but fine dust is accumulated in the dust bag 12 in the vacuum cleaner main body 10.

Therefore, the dust collecting bag 12 in the cleaning main body 10 should be periodically cleaned. In the case of the non-cyclic dust collecting bag 12, dust is blown to clean the dust collecting bag 12 due to accumulated dust. In this case, when the exchangeable dust collecting bag 12 is used, there is an inconvenience in that the dust collecting bag 12 needs to be replaced periodically.

In addition, since the dust collecting chamber 10a is to be provided in the cleaner main body so that the dust collecting bag 12 can be mounted, the volume of the vacuum cleaner main body 10 becomes large, which causes inconvenience of cleaning using a vacuum cleaner.

In addition, due to the interference of air that flows into the cyclone dust collector 19a and descends from the bottom surface, the fine dust collected on the bottom surface of the cyclone dust collector 19a is unstable and is raised in the air. It is ubiquitous and flows into the cleaning base 10.

Therefore, such fine dust flows into the suction motor 11, thereby degrading the performance of the suction motor 11, thereby lowering the durability of the cleaner as a whole.

The present invention has been made to solve the above problems, and an object thereof is to provide a cyclone dust collector of a vacuum cleaner having an improved structure to increase the collection efficiency of the cleaner.

On the other hand, the inside of the waste container 41 is in close contact with the inner circumference of the waste container 40 to support the rim of the filter 42 and the waste container body 41 from the support body 42b. It further includes a filter support member 42a having a plurality of support teeth 42c extending in a curved shape to reach a predetermined height downward. A filter 42 is installed to cover the filter support member 42a, and the filter 42 is supported by the support ribs 42c so as to increase the filtering area of the filter 42. It is mounted while being held in a hemispherical protruding position downward. One side surface is opened on the outer circumferential surface of the waste container 41, and the second air duct body 46 is coupled to the side of the waste container body 41 so that the open side covers the second air inlet 43. Then, the second air inlet pipe 48 through which the air discharged from the centrifugal barrel body 31 flows is connected through the second air duct body 46.

At this time, the inlet formed at one end of the second air inlet pipe 48 protrudes at a predetermined length in the center of the upper portion of the centrifuge barrel 30, the other end penetrates the bottom surface and side surfaces of the waste container body 41. It is connected to the second air duct body 46. Although not shown, the connection of the second air inlet pipe 48 is a variety of techniques known in the art to guide the air from the central upper portion of the centrifuge barrel body 31 to the second air duct body 46.

As illustrated in FIG. 6, air including dirt introduced through the first air inlet pipe 38 is introduced into the centrifuge chamber 37 through the first air duct 35.

The introduced air is lowered via the funnel pipe 32 to the bottom surface of the centrifugal cylinder body 31 while forming a vortex air flow by the first air duct body 36 and the first air inlet 33. Air reaching the bottom surface is reversed and rising in a vortex air flow to the second air inlet pipe 48 to which suction power is transmitted by a motor (not shown) driven by the cleaning main body 20 (see FIG. 3). The dirt contained in the air that forms the vortex air flow in the centrifuge chamber 37 is separated by the centrifugal action and discharged to the outside, and the discharged dirt is removed from the wall surface of the centrifuge tube 31 and the funnel pipe 32. The ride is loaded on the floor. At this time, the air reversed and raised from the bottom surface is raised through the inlet of the bottom surface of the funnel pipe 32, the inlet is formed narrower than the inner diameter of the centrifuge tube 31, the air and the bottom surface is lowered from above Interfering with the progress of the air rising in the air flow rate is slowed down. Thus, the slower flow rate causes fine dust contained in the air to accumulate on the floor. Dust loaded on the floor is prevented from piggybacking on the rising air by the funnel pipe 32 which guides the air to rise at a slow flow rate, and thus, the first dust-filtered air enters the inlet of the second air inlet pipe 48. It will flow in.

Next, the air that is primarily filtered out of the centrifugal container 31 is introduced into the waste container body 41 via the second air duct 45, and the sucked air enters the second air inlet 43.
