Description

Cyclone dust collector

The present invention relates to a cyclone dust collector, and more particularly, to a cyclone dust collector including a dust compression unit for compressing dust, and a dust backflow prevention unit for preventing backflow of dust.

1 shows a conventional cyclone dust collector. When the user turns on the operation switch of the vacuum cleaner, dust-containing air flows into the cyclone module 1 and undergoes a centrifugation process. The dust centrifuged in this process is discharged to the dust outlet 2, the discharged dust (4) is accumulated in the dust collecting chamber (3).

After the cleaning is completed, the user must turn off the operation switch of the cleaner and remove the dust 4 accumulated in the dust collecting chamber 3. The dust 4 removal process is performed by removing the cyclone module 1 from the dust collecting chamber 3.

However, when the cyclone module 1 covering the dust collecting chamber 3 is removed, the dust 4 accumulated in the dust collecting chamber 3 does not come into close contact with the dust collecting chamber 3 and is blown back into the air. As the dust blown into the air enters the user's respiratory tract and gives discomfort to the user, dust 4 accumulates again on the cleaned floor, resulting in a problem of reducing the cleaning efficiency.

In addition, there is a problem that the discharged dust (4) flows back through the dust discharge port (2). Such a backflow of the dust 4 causes fouling in the cyclone module 1 and lowers the suction force. In particular, the problem is large when considering that cleaning the inside of the cyclone module 1 is very troublesome.

Cyclone Structure of dust collector

Hereinafter, with reference to the drawings, the structure of the cyclone dust collector 1000 according to the present invention will be described in detail with reference to the drawings.

The cyclone dust collector 1000 according to the present invention may include a cyclone module 100, a dust compression unit 200, and a dust backflow prevention unit 300 as shown in FIGS. 2 and 3. have.

In the cyclone module 100, air containing dust is introduced to separate dust from the air, and the separated dust is collected and the air from which the dust is separated is discharged.

As shown in FIG. 2, the cyclone module 100 may include an inlet 110, a dust outlet 120, and an air outlet 130.

Inlet 110 is a passage through which air containing dust is introduced. The air containing the dust introduced through the inlet 110 rotates inside the cyclone module 100, and the dust is separated from the air by the centrifugal force of the rotation.

In the dust outlet 120, the separated dust is discharged through the above process. At this time, the dust outlet 120 is connected to the dust compression unit 200 to be described later. Preferably, it is inserted into the connection portion 240 of the dust compression unit 200.

In the air outlet 130, only the air from which dust is separated through the above process is discharged.

The dust compression unit 200 is connected to the cyclone module 100 and serves to compress the dust discharged from the cyclone module 100.

The dust compression unit 200 may include a dust compression passage 210, a compressor 220, a compression tension module 230, and a connection unit 240, as shown in FIG. 3.

In the dust compression passage 210, the dust discharged from the dust outlet 120 is accommodated, and serves as a moving passage of the compressor 220 to be described later. In the dust compression passage 210, the accommodated dust is compressed by the movement of the compressor 2200. The shape of the cross section of the dust compression passage 210 may have a cross section of the compressor 220 so that the compressor 220 may move while compressing the dust. It is preferred to produce accordingly.

The compressor 220 moves the dust compression passage 210 and compresses the dust contained in the dust compression passage 210.

Preferably, compressor 220 comprises a helical gear. In this case, since the bit rate of the helical gear is better than that of other gears, such as a spur gear, the movement of the compressor is smooth and the noise is low.

The compression tension module 230 contracts or tensions as the compressor 220 moves. In the absence of such a compression tension module 230, the phenomenon that the dust that was compressed by the compression stroke of the compressor 220 breaks a part or a substantial portion of the shrink stroke frequently occurs. However, the compression tension module 230 is contracted according to the compression stroke of the compressor 220, and during the contraction stroke of the compressor 220, the compression tension module 230 is tensioned apart from the compressor 220 by a predetermined distance to break the compressed dust. It can be minimized.

The dust outlet 120 of the cyclone module 100 may be inserted into the connection portion 240. Through this, the dust discharged through the dust outlet 120 may move to the dust compression passage 210 connected to the connection portion 240.

The dust backflow prevention part 300 may be connected to the dust compression part 200, and may include a discharge passage 310 and a door 320.

The discharge passage 310 is a passage through which the dust compressed in the dust compression unit 200 is discharged.

The door 320 may open and close the discharge passage 310, and after the dust compression unit 200 compresses the dust, the door 320 opens the discharge passage 310 to discharge the compressed dust discharge passage 310. Discharge through, and after the compressed dust is discharged the door 320 closes the discharge passage (310).

Preferably, the movement of the door 320 as described above may be by the motor. In this case, the door 320 may rotate to open and close the discharge passage 310. As an example, as shown in FIG. 4, the gears may be eccentrically rotated to open and close the discharge passage 310. It is also possible to utilize gear ratios, including multiple gears.

Preferably, the cyclone dust collector 1000 according to the present invention is included in a cyclone vacuum cleaner. In this case, when dust is introduced into the cyclone dust collector 1000, the introduced dust may be filtered, compressed and discharged.

Explanation of how to operate

Hereinafter, a method of operating the cyclone dust collector 1000 according to the present invention will be described in detail with reference to the accompanying drawings.

Operation of the cyclone dust collector 1000 according to the present invention begins by turning on the power of the cyclone vacuum cleaner including the cyclone dust collector 1000.

The motor of the powered-on cyclone vacuum cleaner starts to drive and makes the inside of the vacuum cleaner relative to the outside of the vacuum cleaner. Air outside the cleaner is sucked into the cleaner in a relative vacuum state.

The air sucked into the cleaner includes dust, and the air containing the dust is introduced into the inlet 110 of the cyclone module 100 illustrated in FIG. 2. The air containing the dust introduced into the inlet 110 rotates inside the cyclone module 100, and the dust is separated and discharged to the dust outlet 120 by centrifugal force, and the air is discharged to the air outlet 130.

The dust discharged to the dust outlet 120 passes through the connection part 240 and is accommodated in the dust compression passage 210. The dust contained in the dust compression passage 210 is collected in a predetermined amount, and the collected dust is pushed by the compression stroke of the compressor 220 and moves toward the compression tension module 230. In this case, the dust collection amount may be adjusted by the movement period of the compressor 220 which is preset by the user or by the user of the cleaner.

Compressor 220 continues to move and contract the compression tension module 230. As the compressor 220 moves, the compression tension module 230 contracts to a limit value. In this process, the dust between the compressor 220 and the compression tension module 230 is compressed.

When the dust is compressed, the compressor 220 starts the contraction stroke. In accordance with the contraction stroke of the compressor 220, the compression tension module 230 also begins to tension. At this time, the compression tension module 230 pursues the compressor 220 in a state where the minimum space occupied by the compressed dust is spaced apart. The compressed dust pushed out by the compression tension module 230 is discharged to the dust collecting chamber through the discharge passage 310 in which the door 320 of the dust backflow prevention part 300 located below is opened.

Thereafter, the door 320 rotates to close the discharge passage 310, thereby preventing backflow of the compressed dust discharged to the dust collecting chamber.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
