Description

Dust collector and vacuum cleaner for vacuum cleaners {DUST COLLECTOR AND VACUUM CLEANER}

The present invention relates to a dust collector and a vacuum cleaner for reducing noise and improving fine dust separation efficiency.

Dust collectors of vacuum cleaners, such as an upright type or canister type, which separate dust by centrifugation, are separated from the primary separator (primary cyclone) and secondary separator to improve the efficiency of dust separation. It has a so-called multicyclone structure which consists of a part (secondary cyclone part).

The dust collector separates and collects relatively large and heavy foreign matters from the air in the primary separator, and separates and collects small and light dust in the secondary separator. This improves the separation and collection efficiency of dust than the dust collector provided with one separator (cyclone).

However, the separation of dust by centrifugation alone does not effectively filter out fine dust. In addition, there is a problem that the noise is generated in the flow path through the primary and secondary separation unit and the exhaust flow path to discharge the air to the outside of the dust collector.

Therefore, a number of prior arts have been disclosed to solve the problems of the above-described dust collector having a multicyclone, and examples of such prior arts include US Pat. Nos. 6,334.234 and 3,425,192.

The prior arts are configured to mount a filter on the exhaust side of the secondary cyclone in a dust collector having a primary cyclone and a secondary cyclone. The prior arts of this configuration reduce the amount of fine dust discharged to the outside by filtering out fine dust not separated in the secondary cyclone using a filter. In addition, the noise is absorbed by the air flow discharged from the dust collector by the filter to reduce the noise.

However, the conventional techniques are configured to discharge the dust separated by the filter located on the exhaust side of the secondary cyclone through the side of the dust collector, thereby moving the air discharged through the side of the dust collector to the fan motor unit. Since a separate air flow path must be configured, the construction of the vacuum cleaner body is complicated.

In addition, by configuring a separate flow path for exhausting the overall length of the flow path has a problem that the pressure loss occurs. The occurrence of such a pressure loss acts as an overload of the fan motor unit, which shortens the life of the fan motor unit, and also reduces the dust separation efficiency as the suction force decreases.

Therefore, the present invention for solving the above-mentioned problems of the prior art provides a dust collector and a vacuum cleaner having the same, the pressure loss is reduced.

Hereinafter, an operation process of the dust collector 100 mounted on the vacuum cleaner 200 will be described with reference to FIG. 3.

When the vacuum cleaner 200 equipped with the dust collector 100 is driven, a suction force generated by a fan motor unit (not shown) is generated.

The suction force sucks the outside air including foreign matter such as dust on the cleaning surface through a hose nozzle (not shown) or the brush assembly 20.

The air introduced through the hose nozzle (not shown) or the brush assembly 20 passes through the inlet 151 connected to the suction passage (not shown) formed inside the body 10. ) Is introduced into the primary cyclone unit 180 located in the primary dust collecting region 193 of the dust container 190.

The air including the foreign matter introduced into the primary cyclone unit 180 is rotated about the primary exhaust pipe 181 to separate the large and heavy foreign matter first by centrifugal force. At this time, foreign matter such as separated dust is collected in the lower part of the primary dust collecting region 193.

The air from which the foreign matter is separated is filtered again while passing through the grill member 182 and then discharged to the secondary cyclone unit 170 through a space between the primary exhaust pipe 181 and the grill member 182.

The air introduced into the secondary cyclone unit 170 is introduced into the plurality of secondary cones 152 and then rotates around the secondary exhaust pipe 131 so that foreign matters such as light and small fine dust are secondary. Are separated. At this time, foreign matters such as fine dust separated are collected in the secondary dust collection area 194.

The air from which small and light foreign matter such as fine dust is separated from the secondary cyclone unit 170 is discharged to the upper portion of the secondary cyclone unit 170 through the secondary exhaust pipe 131. The discharged air passes through the filter member 120 from the lower part to the upper part, and fine foreign substances such as fine dust which are not separated from the secondary cyclone part 170 are filtered by the filter member 120 in the third order.

The air filtered by the filter member 120 in the third foreign matter is switched 180 degrees by the flow direction to the inside of the primary exhaust pipe 181 and the dust collecting device through the exhaust port (195a) formed in the dust cover lower cover 195 ( After discharged to the outside of the 100, it is discharged to the outside of the vacuum cleaner 200 via a pre-filter (not shown), a fan motor unit (not shown), an exhaust filter (not shown), and the like.

As described above, the dust collector 100 of the present invention separates the introduced air by the primary cyclone unit 180, the secondary cyclone unit 170, and the filter member 120 three times. Improve the separation efficiency of foreign matter such as dust.

In addition, the dust collector 100 is discharged from the inside of the dust collector 100 to the outside by the filter member 120, since the air from which the foreign matter is removed is discharged through the filter member 120 from the bottom to the upper direction. The noise is reduced. In other words, the filter member 120 serves as a sound absorbing material that effectively blocks the flow noise leaking from the cyclone at the same time as the dust filtering.

In addition, the air passing through the filter member 120 is introduced into the primary exhaust pipe 181 through the upper portion of the primary exhaust pipe 181 and then, through the exhaust port 195a of the dust cover lower cover 195, that is, dust collection. Since it is discharged through the center of the device 100, the internal noise of the dust collector 100 is further prevented from being discharged to the outside of the dust collector 100.

In addition, since the air from which the foreign matter is separated is discharged through the dust container lower cover 195 exhaust port 195a of the lower part of the dust collecting device 100, the air discharged from the dust collecting device 100 to the outer region of the dust collecting device 100. The pressure loss is also reduced by reducing the total air flow path of the vacuum cleaner 200 by not forming a separate air flow path for exhaust.

In the above description of the exemplary embodiment of the present invention, the upright vacuum cleaner has been described as an example, but the present invention can be applied to any vacuum cleaner including a dust collector such as a canister vacuum cleaner, a backpack vacuum cleaner, and a handy vacuum cleaner.

The present invention can be applied to cleaning devices, such as industrial, household, commercial cleaners.
