BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a cyclone dust collector installed on a vacuum cleaner main body to filter and collect dust by a cyclone principle.

As is well known, a vacuum cleaner is a household appliance that generates a strong air suction input in a cleaner body and forcibly sucks contaminants such as dust on the floor, thereby cleaning the dust. A dust collecting means is installed, and a paper filter is generally used as the dust collecting means, but recently, a vacuum cleaner equipped with a cyclone dust collecting device that can be used semi-permanently without an exchange is installed and used in a vacuum cleaner body.

The cyclone dust collector as described above has various forms, but among them, a dual type cyclone dust collector which forms a single cyclone dust collector by connecting the primary cyclone dust collector and the secondary cyclone dust collector. ) Allows the collection of foreign matters to be carried out again, so that the dust collection performance is superior to that of a single cyclone dust collector.

That is, the primary cyclone dust collector is configured to perform the dust collection of relatively large foreign matters, and the secondary cyclone dust collector is configured to perform the dust collection of fine foreign matter not yet collected by the primary cyclone dust collector. .

1 of the accompanying drawings shows the configuration of the above-described dual cyclone dust collector, as shown in Figure 1, the dual cyclone dust collector is a primary cyclone dust collector (1) mounted to the body of the vacuum cleaner And a secondary cyclone dust collector (2), a fan (3) located at the bottom of the main body and transmitting suction force to each of the cyclone dust collectors, and a fan motor (4) for transmitting a driving force to rotate the fan. It is composed.

Here, the primary cyclone dust collecting unit 1 forms an outer body 1a that forms a body and serves as a dust collecting container, and a first air suction passage provided at one side of the upper body of the outer body to suck indoor air. 1b and a first air discharge passage 1c for guiding the air flowing in the outer body to be discharged.

In addition, the secondary cyclone dust collector 2 is an inner body 2a which is positioned to be spaced apart from the inside of the outer body 1a of the primary cyclone dust collector by a predetermined interval, and the air is sucked into the inner body. And a second air intake passage 2b and a second air discharge passage 2c for guiding the air flowing in the inner body to be discharged.

At this time, the second air suction passage 2b is connected to the first air discharge passage 1c of the primary cyclone dust collector 1 so that the air discharged from the primary cyclone dust collector 1 is introduced. The second air discharge passage (2c) is connected to the space where the fan / motor assembly consisting of the fan (3) and the motor (4) is located to transfer the suction force generated by the rotation of the fan (3) Will receive.

In addition, the inner body (2a) has a shape of a cone that is gradually concentrically toward the bottom of the inner body (2a), the dust collecting portion (2d) for dust collection of fine dust separated from the air is located on the lower side of the inner body (2a) It is.

At this time, the dust collector 2d is partitioned with the bottom of the outer body 1a of the primary cyclone dust collector 1 by a separate partition plate 2e, thereby preventing mutual flow.

Therefore, when the fan 3 is rotated by the driving force of the fan motor 4 to generate the suction force, the suction force is the second air discharge passage 2c, the second air suction passage 2b, and the first air discharge passage ( 1c) and the like are sequentially delivered to the first air suction flow path 1b.

Accordingly, it can be understood that the intake of air including various foreign substances in the room is made through the first air intake passage 1b.

In this way, the air and dust sucked into the outer body (1a) in the process of flowing along the inside of the outer body (1a) and the outside of the inner body (2a) to transfer the suction force through the first air discharge passage (1c) The dust is sucked into the inner body 2a, and dust is collected at the bottom in the outer body 1a by its own weight.

At this time, the fine dust among the dust is sucked into the inner body (2a) through the first air discharge passage (1c) as a state contained in the flow of air, the sucked fine dust and air is the inner body (2a) In the process of turning inside, they are separated from each other by the difference in centrifugal force.

That is, the dust having a heavy weight, etc. are relatively largely subjected to the application of the centrifugal force and move downward while rotating along the inner wall surface of the inner body 2a. It flows in the state located in the inner center part of (2a).

Accordingly, the dust separated from the air as described above is collected in the dust collecting portion 2d while moving downward by its own weight, and the air is lifted by the rising air flow generated in the central portion of the inner body 2a, and the second air discharge flow path Through 2c, the fan 3 and the fan motor 4 are discharged into the space where they are located.

However, in the dual cyclone dust collector for collecting the foreign matter while performing the above-described action, the secondary cyclone dust collector 2 should be configured to completely collect even the fine dust, very light fine dust, etc. Through the second air discharge passage (2c) was forced to flow into the space side where the fan 3 and the fan motor 4 is located.

In particular, considering that the primary cyclone dust collector 1 is configured to collect only relatively large dust, the secondary cyclone dust collector 2 has no choice but to continuously introduce fine dust, but the secondary cyclone dust collector 2 As the permissible dust collection capacity of is small, the user often discomforts to discharge various foreign matters collected in the secondary cyclone dust collector to prevent damage to the fan motor.

Therefore, in order to solve the above-mentioned problem, the outside body size of the primary cyclone dust collecting unit has to be increased, and accordingly, the size and weight of the cleaner body also increase, which makes it difficult to implement a vacuum cleaner having a compact design.

In order to solve the above problems, the present invention improves the structure of the cyclone to make the inflow direction of the air substantially coincide with the circumferential direction of the cyclone, and without the need for a secondary cyclone within the primary cyclone. It is an object of the present invention to provide a cyclone dust collector for a vacuum cleaner that can simplify the structure by collecting dust and fine dust completely.

In order to achieve the above object, the present invention is provided with an air inlet formed in the upper end of the body and the air is introduced, and the air discharge port is discharged after the air introduced through the air inlet is filtered, the lower inlet flows into the body A generally cylindrical cyclone body provided with a partition plate for partitioning a dust collecting unit in which dust collected is collected by falling; A suction passage configured to communicate with an air inlet of the body via an outer end of the lower end of the body, and guide air and dirt sucked from the outside into the body; A dust collecting filter installed at an air outlet in the body to filter and discharge dust from the air introduced into the cyclone body; A discharge passage communicating with the air outlet from the outside of the body to guide the air discharged through the dust collecting filter to the outside of the body; Provided is a cyclone dust collector for a vacuum cleaner including a fan / motor assembly formed in communication with one end of the discharge passage in the cleaner body to generate suction force.

According to this, it is not necessary to configure a secondary cyclone because all dust and dirt are filtered out by the dust collecting filter in the cyclone body, and thus the configuration of the cyclone dust collector can be simplified.

In addition, the cyclone body is provided with a partition plate having at least one through-hole is formed so as to partition the dust collecting portion is collected by the dust flows into the lower end of the cyclone body is divided into two semi-circular portion rotatably installed in one direction When the user flips the cyclone body, the two semicircular portions are rotated by their own weight so that the dust collector is opened.

According to this, dirt collected in the dust collector of the cyclone body can be easily removed from the cyclone body.

In addition, the dust collecting filter is made of a polyester material having a stiffness such that the outer surface is wrinkled in a bellows shape and is not deformed by the air suction force, thereby completely filtering even the fine dust sucked into the cyclone body. .

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

As shown in FIG. 2, the cyclone dust collector of the present invention includes a substantially cylindrical cyclone body 200 having an air inlet through which air is introduced into an upper end of a side portion thereof; A suction passage 100 tangentially communicating with an upper end of a side portion of the cyclone body 200 via the lower end of the cyclone body 200; An air outlet through which the air introduced into the cyclone body is discharged is formed in the central portion thereof, and is detachably mounted on the upper end of the cyclone body 200 to form the upper surface of the cyclone body 200. Wow; A dust collecting filter 350 installed at an air outlet of the center of the upper cover 300 to filter fine dust from the flow air to discharge only pure air; It is composed of a discharge passage 500 formed in communication with the dust collecting filter 350 from the outside of the cyclone body 200, the fan / motor assembly 60 for generating a suction force on one side of the discharge passage 500 It is provided.

Although not shown in the drawing, the suction passage 100 is configured to be connected to a suction hose (not shown) connected from the front portion of the outside of the cleaner body (not shown).

And, as shown in detail in Figure 3, the lower portion in the cyclone body 200, a plurality of grooves in the outer peripheral portion to partition the dust collector 210 for collecting dust falling into the cyclone body 200 to fall A disk-shaped partition plate 250 in which 253 is formed is installed, and the partition plate 250 is pivotable at both ends of a pair of hinge brackets 255 installed to face the lower sidewall of the cyclone body 200. It is composed of two semi-circular portion (251, 252) coupled.

In addition, the side wall portion of the cyclone body 200 is formed with a locking jaw 256 for supporting the semi-circular portions 251, 252 of the partition plate 250, the locking jaw 256 As a result, the partition plate 250 is limited to rotate downward and can rotate only in one direction.

Therefore, when the user tilts or flips the cyclone body 200, the semicircular portions 251 and 252 of the partition plate 250 pivot about the hinge bracket 255 by their own weight.

Meanwhile, the dust collecting filter 350 formed on the upper cover 300 is preferably configured to have a cylindrical shape in a state in which the filter 351 is formed to be pleated in a bellows shape, as shown in FIG. 4, which is a filter 351. In order to maximize the amount of filtration while smoothing the flow of air by maximizing the contact area between the filter 351 and the flow air as well as protecting the filter against strong suction by reinforcing the strength of the filter.

In addition, the dust collecting filter 350 is made of a material having sufficient rigidity such that its shape does not change due to suction force upon inhalation of air, and is preferably made of polyester.

In addition, the dust collecting filter 350 is preferably installed to be detachable to the upper cover 300, which is to facilitate the replacement of the dust collecting filter 350.

Hereinafter, the operation of the cyclone dust collector of the present invention configured as described above will be described.

When the user selects the start mode and the operation of the cleaner is started, suction force is generated by the operation of the fan / motor assembly 60 to allow the outside air and the dirt to flow along the suction flow path 100 into the cyclone body 200. Inflow.

At this time, since the suction passage 100 is in tangential communication with the cyclone body 200, air and dirt introduced into the cyclone body 200 through the suction passage 100 are cyclone bodies 200. Spirally rotates along the inner wall surface of the descending, the relatively heavy dirt continues to descend by centrifugal force through the concave portion 253 of the partition plate 250 installed on the cyclone body 200, the dust collector 210 ), And the air and the fine dust having a relatively small weight flow toward the dust collecting filter 350 by the suction force.

Subsequently, the fine dust included in the flow air is filtered by the dust collecting filter 350, and only air passes through the dust collecting filter 350 to be discharged toward the fan / motor assembly 60 through the discharge passage 500.

On the other hand, if you want to remove dirt, such as dust collected in the dust collector 210 below the cyclone body 200, the user separates the cyclone body 200 from the cleaner body (not shown) and then turn over The semi-circular portions 251 and 252 of the plate 250 are rotated by their own weight to open the dust collecting portion 210, and the dirt is dropped and removed.

The above-described embodiment is one example for explaining the cyclone dust collector of the present invention, and the present invention is not limited to this embodiment and various modifications and implementations can be made without departing from the gist of the present invention.

As described above, according to the present invention, since all the dirt including fine dust is collected in one cyclone body, the secondary cyclone is not required, so that the configuration of the device can be simplified, and thus, the manufacturing is easy and the manufacturing cost. It also has the effect of saving.

In addition, since the dust collecting part for collecting the dirt in the cyclone body is partitioned by the partition plate rotatably configured, there is an advantage that the removal of the dirt can be performed more easily.
