The present invention relates to a vacuum cleaner, and more particularly, to a dust collecting unit of a vacuum cleaner. More specifically, when a plurality of cyclone flows are formed in the dust collecting unit of the vacuum cleaner, the storage capacity of the foreign matter filtered by each cyclone flow is further increased, thereby reducing the cleaning cycle of the dust collecting unit, and storing the foreign matter. The present invention relates to a dust collecting unit of a vacuum cleaner in which foreign matter collected in a chamber can be conveniently removed.

A general vacuum cleaner is a device for cleaning the indoor environment by performing the filtering of foreign matter contained in the air sucked by the vacuum pressure inside the device. On the other hand, in order to filter foreign matter in the sucked air is required a filtering device.

As a kind of the filtering device, a porous material through which air passes has been conventionally used, and a method of filtering foreign matter while air passes through the article of the porous material has been widely used.

However, since the porous material is not only inconvenient to recycle, but also difficult to clean the filter, the cyclone method has recently been used as the main filtering device. However, since the cyclone method cannot catch up to fine foreign matter, it is generally required to filter a porous material together with the cyclone type filter.

In order to improve this problem, in recent years, a plurality of cyclone flows are formed in a single dust collecting unit, and a multi-cyclone dust collecting unit has been introduced to completely remove even fine dust without a filter made of a porous material.

On the other hand, in the multi-cyclone dust collecting unit, each cyclone flow is separated so that the air flow by each cyclone flow does not affect the other cyclone flow. Further, in order to prevent foreign substances separated by respective cyclone flows from mixing with each other, respective foreign substance storage chambers in which foreign substances are stored are provided.

Such a multi-cyclone dust collecting unit needs a large space for performing a plurality of cyclone flows therein. Under such a background, the space for the cyclone flow and the collected foreign matter are accommodated without increasing the overall size of the dust collecting unit. Ensuring sufficient space is also an important task.

In addition, it is also an important problem to ensure that foreign matters such as hair collected in the foreign matter storage chamber are conveniently removed. For example, if a foreign material such as hair is caught inside the foreign matter storage chamber, there is a problem that the user needs to tear off and remove the foreign material even when the foreign material is removed. In particular, when a plurality of foreign matter storage chambers are divided and formed separately, it is an important task to form a storage chamber so that foreign matters stored in each storage chamber can be easily removed.

The present invention has been proposed by the above-described needs, and in each of the multi-cyclone dust collecting units, each of the cyclone flows does not affect each other, and the foreign matter storage capacity of each foreign matter storage chamber is maximized. The purpose is to propose a dust collection unit.

In addition, it is an object of the present invention to propose a dust collecting unit of the vacuum cleaner to facilitate the user's convenience by further removing the foreign matter collected in the foreign matter storage chamber when discarding the foreign matter.

The dust collecting unit of the vacuum cleaner according to the present invention for achieving the above object is a first foreign matter separation chamber 423 in which foreign matter is separated from the cyclone flow; A second foreign matter separation chamber 424 in which foreign matter is filtered again after the foreign matter is filtered out of the first foreign matter separating chamber 423; A first foreign matter storage chamber 416 provided under the first foreign matter separation chamber 423; And at least an opening under the second foreign matter separating chamber 424 is accommodated so that the foreign matter separated from the second foreign matter separating chamber 424 is dropped and stored, and a lower end of the second foreign matter separating chamber 424 has a height and a height. A substantially matching second foreign matter storage chamber 417 is included.

According to the configuration of the present invention as proposed, the use of the vacuum cleaner is convenient, and the foreign matter holding capacity of the vacuum cleaner can be obtained. In addition, by increasing the foreign matter holding capacity of the vacuum cleaner, the user does not need to clean the dust collecting unit frequently, there is an advantage that the foreign matter caught in the storage chamber at the time of removing the foreign matter is conveniently removed without the user's manual work.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, the cover 200 is coupled to the base 110 and 150 in a state where the front supporter 170 is fastened to the cover 200 as a separate part. In the motor housing 300, the air sucked through the motor side inlet 172 flows downward in a vertical direction. Then, the introduced air is discharged to the rear by bending the flow direction in the motor housing 300 horizontally.

5 is an exploded perspective view of the dust collecting unit according to the present invention.

Referring to FIG. 5, the dust collecting unit 400 of the present invention does not use a porous filter such as a sponge or the like, and filters foreign matter by cyclone flow. In addition, the cyclone flow may be performed in two or more kinds of separation chambers separated from each other, so that fine dust in the air may be completely filtered.

In detail, the dust collecting unit 400 includes a dust collecting body 406 having a plurality of foreign material separating chambers (see 423 and 424 of FIG. 6) and a plurality of foreign material storage chambers (see 416 and 417 of FIG. 6). A chamber sealing part 415 and 402 are provided in the lower part of the dust collecting body 406 to prevent foreign substances stored in the foreign matter storage chamber 416 and 417 from leaking, and the dust collecting body 406. The exhaust part 407 which is placed above the 406 and exhausted from the dust collection body 406 is guided, and is provided at a predetermined interval above the exhaust part 407 to pass through the exhaust part 407. Spacers 408 for directing air in one direction and cover structures 409, 410, 411, and 412 overlying the spacers 408 are included.

In detail, the cover structure includes a first cover 410 that forms a parent, a third cover 412 and a second cover 409 which are respectively placed in front and rear of the first cover 410, and the first cover 410. A cover insertion hole 411 for fixing the cover 410 and the second cover 409 together is included. The cover insertion slot 411 covers a part of the upper surface portion of the first cover 410 so that the appearance is beautifully implemented, and the first cover 410 and the second cover 409 are simultaneously fixed.

Inside the dust collection body 406, a conical filter 405 for smoothly separating the dirt in the cyclone flow, and a blocking portion for preventing the re-scattering of foreign matter collected under the conical filter 405 ( 404, a flow preventing plate 403 is formed below the blocking portion 404 to slow the flow rate of the air to be rotated, so that the foreign matter sinks inside the dirt storage chamber. Here, the blocking part 404 and the flow preventing plate 403 may be formed in one body, and the conical filter 405 may be formed as a separate component.

In addition, an opening and closing button 413 is placed on one side of the first cover 410, and one end of the opening and closing button 413 is in contact with the opening and closing movement by the push operation of the opening and closing button 413 Lever 414 is released. In addition, the other end of the open / close lever 414 is connected to the first chamber sealing part 415. Therefore, by the pressing operation of the opening and closing button 413, the opening and closing lever 414 is rotated about a predetermined hinge point. When the contact portion between the first chamber sealing portion 415 and the opening / closing lever 414 is separated from the other end of the opening / closing lever 414, the first chamber sealing portion 415 may set a hinge point by its own weight.

In addition, a separation plate 437 is formed on the upper surface of the dust collecting body 406 to partition the first foreign matter separating chamber 423 and the second foreign matter separating chamber 424 and form a flow path.

FIG. 6 is a cross-sectional view taken along line II ′ of FIG. 3 and with reference to FIG. 6, the internal structure of the dust collecting unit 400 and the operation of the dust collecting unit will be described in detail.                     

First, as described in detail with reference to FIG. 5 and the related description, in the dust collecting unit 400 according to the present invention, a dust collecting body 406 and a lower side of the dust collecting body 406 are selectively sealed. Sealing parts 402 and 415, a conical filter 405 accommodated inside the dust collecting body 406 to increase dust collection efficiency, a blocking part 404 to prevent re-splash of the collected foreign matter, and cyclone The flow velocity of the flow is lowered so that foreign matters fall, and the flow preventing plate 403 which prevents the lifting of dust and the air placed on the upper side of the dust collecting body 406 so that the air exhausted from the dust collecting body 406 flows smoothly. An exhaust portion 407, an interval portion 408 for collecting the air passing through the exhaust portion 407 in one direction, and cover structures 409 and 410 placed on an upper side of the exhaust portion 407 ( 411 and 412 are included.

The configuration of the dust collecting body 406 will be described.

The dust collecting body 406 is provided with a plurality of walls extending up and down, the outer wall 418 formed on the outermost, the intermediate wall 419 formed inside the outer wall 418, and the intermediate wall ( An inner wall 420 formed inside 419 is included. The intermediate wall 419 and the inner wall 420 are not formed at intervals through which the dust collecting unit side suction port 401 passes, thereby preventing the dust collecting unit side suction port 401 from interfering with each other.

The space between the outer wall 418 and the intermediate wall 419 is the first foreign matter storage chamber 416, and the space between the intermediate wall 419 and the inner wall 420 is the second foreign matter storage chamber 417. And extends to the bottom surface of the first chamber sealing part 415. The inner space of the inner wall 420 becomes the first foreign matter separation chamber 423. However, according to the shape of the dust collecting unit 400 in detail, the purpose of using the space may vary.                     

The operation or operation by the above-described configuration will be described in detail based on the flow direction of air. First, the dust is introduced into the dust collecting unit 400 through the dust collecting unit side suction port 401. Here, the dust collecting unit side suction port 401 is in contact with the front supporter 170 on the outside, and communicates with the first foreign matter separation chamber 423 on the inside to introduce the outside air. In addition, a first inflow guide 421 is inward from the inner wall 420 so as to guide the flow direction of air in the direction of the inner circumferential surface of the first foreign matter separation chamber 423 inside the dust collecting unit side suction port 401. Protrudes.

During the cyclone flow of air in the first foreign matter separation chamber 423, the foreign matter falls downward and clean air passes through the opening of the conical filter 405 and is discharged upward. The conical filter 405 is applied in this way because the dust collecting unit side suction port 401 is located on the upper side, the cyclone flow of the high speed rotation occurs in the upper portion of the conical filter 405, and the relatively low speed in the lower portion. Because cyclone flow occurs. That is, in the high-speed cyclone flow, the foreign material is rotated more outwardly, but in the low-speed cyclone flow, the foreign material is spread more inward, so that the filter member is applied in a conical shape to filter the foreign material. desirable.

The conical filter 405 is seated at the center of the separation plate 437 forming the upper wall of the first foreign matter separation chamber 423, it may be provided in a structure that can be selectively separated from the separation plate (437). In addition, the conical filter 405 is formed with a plurality of openings, of course, the air flows in from the outside into the inside.                     

Here, the blocking portion 404 is placed under the conical filter 405 in order to prevent the re-splash of the falling foreign matter, as shown, the blocking portion 404 is expanded in diameter downwards, the foreign matter The rise of is blocked and do not get excited. In addition, a flow preventing plate 403 is formed below the blocking portion 404 at regular intervals, so that the cyclone air flow is not reached with respect to the foreign matter once collected, thereby eliminating the phenomenon of the foreign matter being lifted up. .

In addition, the foreign material filtered in the first foreign matter separation chamber 423 is stored in the first foreign matter storage chamber 416 below. Here, the first chamber sealing part 415 is placed at the lower end of the first foreign matter storage chamber 416 to prevent leakage of the stored foreign material.

On the other hand, foreign matter that has sunk on the bottom surface of the first foreign matter storage chamber 416 is caught on the outer wall forming the second foreign matter storage chamber 417 to prevent the lifting of foreign matter. In other words, the lower end of the wall of the second foreign matter storage chamber 417 is sealed by touching the bottom surface of the first foreign matter storage chamber 416. Therefore, the foreign material rotated inside the first foreign matter storage chamber 416 is caught by the outer wall of the second foreign matter storage chamber 417 is not rotated. In particular, when a long foreign material such as hair cannot be rotated by being caught by a large outer wall of the second foreign material storage chamber 417, the hair is wound around a short distance without being rotated many times, so that the removal process can be conveniently performed later. Can be.

On the other hand, the air flowing through the conical filter 405 to the upper side of the separation plate 437 is largely filtered foreign matter. Therefore, there is a further need for cyclone flow to allow secondary fines to be filtered out. Hereinafter, the cyclone flow performed further will be described in detail.

Air passing through the conical filter 405 is introduced into the plurality of second foreign matter separation chamber 424 through the second inlet guide 422. In addition, since the second inflow guide 422 directs the inner circumferential surface of the second foreign matter separation chamber 424 in a tangential direction, air introduced into the second foreign matter separation chamber 424 may be formed in the chamber. Cyclone flow occurs.

The foreign matter separated by the cyclone flow in the second foreign matter separation chamber 424 is dropped downward and stored in the second foreign matter storage chamber 417. In order to prevent the dropped foreign material from scattering again, the lower portion of the second foreign matter separating chamber 424 is contracted. The lower end of the second foreign matter storage chamber 417 is in contact with an inner surface of the first chamber sealing part 415 in order to prevent leakage of foreign matter collected in the second foreign matter storage chamber 417. It is sealed by the 2 chamber sealing part 402.

In detail, the second foreign matter storage chamber 417 is an inner space formed by the intermediate wall 419 and the outer wall 420, and as described above, an opening space below the second foreign matter separation chamber 424. As a space communicating with, the space separated from the separation chamber is stored.

In addition, the second foreign matter storage chamber 417 is formed in the lower part of the place where the second foreign matter separation chamber 424 is disposed, and the first inclined surface (at a plurality of places) to allow the separated foreign matter to fall downward. 440 is formed. Therefore, the foreign matter once separated from the second foreign matter separation chamber 424 may fall down on the first inclined surface 440.

In addition, the foreign material primarily dropped from the first inclined surface 440 falls down more quickly through the second inclined surface 442. To this end, the second inclined surface 442 has a steeper slope than that of the first inclined surface 440. In other words, the first inclined surface 440 may be provided at a relatively wide interval so that the foreign matter separated from the second foreign matter separating chamber 424 may be guided, and the second inclined surface 442 may be once the first inclined surface ( 440 is a steep slope formed so that the foreign material descends on the surface.

As can be understood from the above description, the second foreign matter storage chamber 417 includes a primary storage unit 446 partitioned into an inner space of the second inclined surface 442. In other words, the second foreign matter storage chamber 417 is stored only in the other space beyond the first storage unit 446 after the first foreign matter accumulated in the primary storage unit 446 is defined as the inner space of the second inclined surface 442. Will be.

On the other hand, as described above, the second inclined surface 442, which is the outer wall of the primary storage unit 446, acts as a catching part to which foreign substances are caught, and the primary storage unit 446 is formed with a relatively large area. Therefore, even when foreign matter is caught, it can be easily removed. In other words, when the foreign material is caught on the outer wall of the second inclined surface 442, the foreign material such as hair is wound in one rotation or in a rotated state without being caught many times by the large volume of the primary storage unit 446, and thus is easily removed. In addition, since the second inclined surface 442 is formed to be inclined downward, when the first chamber sealing portion 415 is opened, the foreign material is moved along the second inclined surface 442 along the inclined surface. It can come down easily and foreign material can be removed.

On the other hand, after the foreign material is filtered in the second foreign matter separation chamber 424, the foreign matter is introduced into the exhaust part 407 via the exhaust part side suction port 425, and the exhaust part 407 and the spacer part 408 are separated. Gather in the space between them. Here, the diameter of the exhaust side suction port 425 is smaller than the inner diameter of the second foreign matter separation chamber 424, the foreign matter of the second foreign matter separation chamber 424 is the exhaust portion ( The possibility of flowing together with 407 can be further reduced. In other words, foreign matter gathered on the inner circumferential surface of the second foreign matter separation chamber 424 is not discharged through the exhaust side inlet 425.

As described, the air filtered by foreign matter by two cyclone flows is introduced into the motor side inlet 172 and flows into the motor. Then, after passing through the motor is exhausted to the rear of the vacuum cleaner body (100).

Meanwhile, a predetermined cover structure is further formed on the upper portion of the spacer 408. In detail, the first cover 410 constituting the overall cover structure, the third cover 412 and the second cover 409 protecting the front and rear of the first cover 410, and the first cover A cover insertion hole 411 is provided at 410 to fix the second cover 409.

The second foreign matter storage chamber 417 has a function of storing as much foreign matter separated from the first foreign matter separation chamber 424 as possible, and the foreign matter stored in the first foreign matter storage chamber 416 is not caught and moved. The function to ensure accurate storage is performed simultaneously. This function and each configuration of the second foreign matter storage chamber 417 will be described in detail.

7 is a perspective view illustrating the structure of the second foreign matter storage chamber in the dust collecting unit according to the present invention.

Referring to FIG. 7, the second foreign matter storage chamber 417 is formed integrally with the dust collecting body 406 and extends downward in a predetermined shape.

In detail, the upper end of the second foreign matter storage chamber 417 is formed in an arc shape along the position where the second foreign matter separation chamber 424 is disposed and extends downward. Then, at four locations extending downward, a primary storage unit 446 is formed in which the foreign matter separated from the second foreign matter separation chamber 424 is first stored. Preferably, at least two primary storage units 446 are formed in order to secure a wide space for accommodating foreign materials and to allow foreign materials to be rotated in the first foreign matter storage chamber 416.

In addition, the first inclined surface 440 is formed to be inclined at a predetermined angle so that the foreign matter separated from the second foreign matter separation chamber 424 is smoothly dropped to be collected into the primary storage unit 446. The first inclined surface 440 is provided in a state where there is no horizontal portion in a relatively wide area so that foreign matters separated from all the second foreign matter separation chambers 424 are guided to the primary storage part 446 side. In addition, a second inclined surface 442 having a steeper inclination angle than that of the first inclined surface 440 is formed at a portion further extending downward from the first inclined surface 440. Of course, the inner space of the second inclined surface 442 forms a primary storage unit 446 in which foreign materials are collected, even inside the second foreign matter storage chamber 417.                     

In addition, the primary storage unit 446 is shown as being formed at equal intervals in the place, but is not limited to this, more than that may be formed.

On the other hand, the second inclined surface 442 not only serves as the primary storage unit 446 in which foreign matter is collected in the inner space, but also the outer wall is shaken because the foreign matter trapped in the first foreign matter storage chamber 416 is caught. It serves as a locking portion that does not. In addition, since the primary storage unit 446 is provided in a relatively large area in the shape of a circular frame, even if a long foreign material such as a hair is caught, the user can be quickly removed by a pulling force downward. Of course, since the second inclined surface 442 has a predetermined inclination angle, the user can smoothly remove the foreign material by pulling the foreign material downward.

In addition, since the lower end of the second inclined surface 442 is in contact with the inner surface of the second chamber sealing portion 402, foreign matter collected in the primary storage portion 446 is transferred to the first foreign matter storage chamber 416. Not only does not escape, there is an advantage that does not occur between the air flow.

The overall operation to the operation of the vacuum cleaner body 100 together with the operation of the dust collecting unit 400 will be described in detail with reference to the longitudinal cross-sectional view of the vacuum cleaner shown in FIG. 8.

Referring to FIG. 8, the outside air flows into the vacuum cleaner body 100 through the main body side suction port 171 connected to the connector 6, and the inside of the dust collection unit 400 through the dust collection unit side suction port 401. Flows into. In addition, after the foreign matter is filtered by the operation and action as described above, the dust collecting unit 400 is introduced into the motor housing 300 through the motor side inlet 172.

At this time, the inlet is directed upward in the state in which the motor housing 300 is erected in the vertical direction. Therefore, the air introduced horizontally through the dust collecting unit 400 is turned downward to be directed downward. Then, after passing through the motor housing 300, it is discharged to the outside through the main body exhaust port 302 provided on the back of the vacuum cleaner body 100.

9 is a perspective view of a foreign substance storage chamber according to another embodiment of the present invention.

Referring to FIG. 9, the second foreign matter storage chamber 417 according to the present embodiment is mostly the same as the original embodiment shown in FIG. 7, except that the second foreign matter storage chamber 417 is provided with a structure and coupling. The only difference is in the way it works.

In detail, when the second foreign matter storage chamber 417 cannot be formed integrally with the dust collecting body 406 due to difficulty of injection, etc., the second foreign matter storage chamber 417 extends upward on the outside of the second foreign matter storage chamber 417. The fastening boss 445 is further formed, and another connection part corresponding to the fastening boss 445 is formed in the dust collecting body 406. Then, the fastening tool such as a screw is inserted into the fastening boss 445 and the connection portion, so that the second foreign matter storage chamber 417 can be firmly fixed to the dust collecting body 406. A mounting groove 441 is provided at an upper end of the wall of the second foreign matter storage chamber 417 so that the second foreign matter storage chamber 417 can be stably sealed to the lower ends of the intermediate wall 419 and the inner wall 420. ) Is preferably formed.

On the other hand, the foreign matter separated from the second foreign matter separation chamber 424 by the first inclined surface 440 smoothly falls into the primary storage unit 446, and the outer wall of the second inclined surface 442 A long foreign matter such as hair collected in the first foreign matter storage chamber 416, a function of allowing foreign matter caught on the outer wall of the second inclined surface 442 to be easily removed downward by an inclination; The lower end of the second inclined surface 442 touches the inner surface of the second foreign matter storage chamber 415 so that the foreign matter of the second foreign matter storage chamber 417 does not count to the outside, and the inside of the second inclined surface 442. The function of the space as the primary storage unit 446 is the same as already described in the original embodiment.

By the vacuum cleaner and the dust collecting unit of the vacuum cleaner of the present invention as proposed, it is possible to obtain an advantage that the foreign matter can be separated smoothly in the state that the filter of the porous material is not mounted.

In addition, since the structure of the dust collecting unit is improved, there is an advantage that a space in which foreign matter is stored in the lower portion of the dust collecting unit can be provided widely. As the foreign matter storage chamber is provided in this way, the size of the dust collecting unit is not increased, but the volume of the foreign matter storage chamber is further obtained.

In addition, the foreign material stored in one foreign material storage chamber 416 is caught on the outer wall of the other foreign material storage chamber 417, so that the foreign material does not swing, it is possible to prevent the foreign material rocking. Furthermore, even if a long foreign matter such as hair can be conveniently removed by the inclined surface of the foreign matter storage chamber, there is an advantage that the use of the dust collecting unit is convenient.

The present invention is not limited to the embodiments as described above, and those skilled in the art will be able to easily propose other embodiments within the scope of the same idea. Such embodiments will also be included within the scope of the invention.

The present invention has the advantage that the foreign matter holding capacity of each foreign matter storage chamber is maximized while each cyclone flow does not affect each other. In addition, since the foreign matter storage chamber is completely sealed, foreign matters collected in the foreign matter storage chamber are not leaked to the outside, thereby improving the reliability of the product.

In addition, since the foreign matter is conveniently removed along the inclined surface when removing the foreign matter caught in the foreign matter storage chamber, the user's convenience can be improved.
