Description

Multi cyclone vacuum cleaner

The present invention relates to a cyclone dust collector capable of collecting various foreign substances such as dust using the cyclone principle, and more particularly, to a vacuum cleaner to which the cyclone dust collector is applied.

In general, a cyclone dust collector is a device that discharges the air to the outside of the foreign matter that rotates with the air using a centrifugal force and collects only the foreign matter from the air.

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 to 3 illustrate a state in which the aforementioned dual cyclone dust collector is applied to an upright vacuum cleaner.

A dual cyclone suction cleaner will be described in more detail with reference to the following.

First, the vacuum cleaner having the dual cyclone dust collector is located in the main body, the primary cyclone dust collector (1) and the secondary cyclone dust collector (2) attached to the main body, and located at the bottom of the main body. It consists largely of the fan 3 which transmits a suction force to each cyclone dust collector, and the fan motor 4 which transmits a driving force to rotate this fan.

At this time, the primary cyclone dust collecting unit forms an outer body that serves as a dust collecting body and the first air suction flow path provided on one side of the upper body of the outer body to suck the indoor air, and the outer body It consists of a first air discharge passage for guiding the air flowing in the discharge.

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 3 and the fan motor 4 are located to receive the suction force generated by the rotation of the fan 3.

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 lower side of the inner body (2a) is a dust collecting portion for collecting the dust dust separated from the air (2d) is located have.

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) the air transfers 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 to move downward while rotating along the inner wall surface of the inner body 2a, and the air whose negligible weight is hardly subjected to the centrifugal force is applied to the inner body. 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, although the secondary cyclone dust collector 2 of the dual cyclone dust collector which collects the foreign matter while performing the above-described action should be configured to completely collect even the fine dust, the relatively light fine dust, etc. The fan 3 and the fan motor 4 were forced to flow to the space side through the air discharge passage 2c.

This is because the secondary cyclone dust collector 2 is configured to perform the dust collection of the foreign matter using the cyclone principle in the same manner as the primary cyclone dust collector 1, and thus, the microcyclone dust collector 2 cannot be separated from the air by the cyclone principle. Dust was forced to enter the space where the fan motor 4 is located together with the air.

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

In addition, in order to solve the above-mentioned problem, the outer body size of the primary cyclone dust collecting part has to be largely applied to only the upright vacuum cleaner.

That is, the dual cyclone dust collector having the above-described structure has always had a problem of causing inconvenience to many users due to the small allowable dust collection capacity for applying to the canister vacuum cleaner.

An object of the present invention is to provide a new type of vacuum cleaner to maximize the allowable dust collecting capacity of the primary cyclone dust collecting unit constituting the cyclone vacuum cleaner.

In addition, the present invention enables to completely remove the fine dust discharged to the space side where the fan motor is located without collecting dust in the secondary cyclone dust collecting unit, and at the same time, it is possible to smoothly remove the fine dust collecting portion again. The purpose is to enable cleaning to be performed.

That is, in one embodiment of the present invention, a dual cyclone dust collector consisting of the primary cyclone dust collector 100 and the secondary cyclone dust collector 200 is applied to the inside of the main body 10 of the canister type vacuum cleaner. The allowable dust collection capacity of the dust collecting container 110 of the primary cyclone dust collecting part 100 constituting the cyclone dust collecting device is proposed to be configured to maximize.

At this time, the dust collecting container 110 has been configured to enable a smooth mounting from within the cleaner body 10 of the vacuum cleaner for smooth discharge of various foreign matters collected therein.

To this end, an embodiment of the present invention is characterized in that the main body 10 of the vacuum cleaner is improved to be applied to the multi-cyclone dust collector.

That is, the cleaner main body 10 according to the present invention is mounted on the upper body of the lower body 11 and the lower body 11, the mounting of the fan 300 and the fan motor 400, the fan 300 and the fan motor ( While forming a space to be mounted 400 and the front side is composed of an intermediate body 12 to form a space to be seated of the dust collector 110, and an upper cover 13 covering the intermediate body .

At this time, the upper cover 13 is mounted on the upper portion of the intermediate body 12 so that the secondary cyclone body 210 can be positioned on the upper space of the intermediate body 12 and the space is provided. It is closed so that it can be sealed from the outside.

Meanwhile, the primary cyclone dust collector 100 applied to the cleaner body 10 as described above is connected to the dust collector 110 and the suction hose 40 constituting the vacuum cleaner, and thus the cleaner body 10. The first air suction flow path 120 and penetrates the through hole (13a) formed in the front side of the upper body 13 of the upper part of the dust collecting tube 110 and communicates with the inside of the dust collecting tube 110, As a state, the first air discharge passage 130 through which the air from which foreign matters are separated is discharged.

At this time, the dust collecting container 110 is to open the upper portion, the open upper portion is connected to the end of the first air intake passage 120 and the first air discharge passage 130 is integrated. 141 is configured to be selectively closed by the dust collecting cover 140 is formed.

In addition, the first air discharge passage 130 is formed as a perforated tube formed with a plurality of through holes 131 along the circumference thereof, and is relatively larger than the size of the through holes 131 among various foreign substances sucked into the dust collector 110. It is configured to prevent the discharge of various bulky foreign substances.

In addition, the secondary cyclone dust collector 200 is located above the dust collector 110 of the primary cyclone dust collector 100 described above, and the air flows in a direction orthogonal to the direction in which the dust collector 110 is formed. Secondary cyclone body 210 is installed to be made, and the second air intake flow path 250, the second air discharge flow path 220, respectively connected to the secondary cyclone body 210, foreign matter discharge path 240 Large configuration)

In this case, one end of the second air intake passage 250 extends from an air outlet side of the first air discharge passage 130 constituting the first cyclone dust collecting part 100, and the other end of the second cyclone body It is configured to communicate with the inside of the secondary cyclone body 210 through one end of the (210).

In addition, the second air discharge passage 220 passes through the central side of the side surface of the secondary cyclone body 210 in a state where one end thereof is close to the position where the second air suction passage 250 is connected. It is formed to extend into the interior of the body 210, the lower body in the rear body, that is, the fan 300 and the fan motor 400 is configured to be connected to the seated space.

In addition, the foreign matter discharge passage 240 has one end connected to the other end of the secondary cyclone body 210, which is the opposite side of the side where the second air suction passage 250 is located, and the other end thereof is a separate second end. The dust collecting container 230 is configured to be connected with the inside.

In the above, the second dust collector 230 may be configured separately, but the discharge is integrated with the dust collector 110 by integrating on the circumferential surface of the dust collector 110 constituting the primary cyclone dust collector 100. It is more advantageous to configure to be done at one time.

Accordingly, in the present invention, as shown in FIG. 5, the dust collector 110 of the primary cyclone dust collector 100 and the second dust collector 230 of the secondary cyclone dust collector 200 are integrated with each other.

In addition, the inner side of the secondary cyclone body 210 is gradually expanded toward the side where the second air discharge passage 220 is located at the central side opposite to the side where the one end of the second air discharge passage 220 is located. The expansion pipe portion 260 is formed to protrude.

The expansion unit 260 as described above is introduced into the secondary cyclone body 210 to form an airflow of air discharged through the second air discharge passage 220 among air and various fine foreign matters performing cyclone movement. In addition to this, the air stream of the air does not reach the position where the foreign substance discharge passage 240 is formed, thereby preventing the foreign substances such as fine dust discharged through the foreign substance discharge passage 240 from being piggybacked on the air discharged.

According to the first embodiment of the present invention having such a structure, when the multi-cyclone dust collector is applied to the main body 10 of the canister type vacuum cleaner, the size of the main body 10 of the cleaner may not be larger than the general size. It is possible to maximize the dust collection space of the primary cyclone dust collecting part 100, that is, the allowable dust collecting space of the dust collecting container 110.

Hereinafter, with reference to Figure 6 showing the operation of the multi-cyclone vacuum cleaner according to an embodiment of the present invention configured as described above in detail as follows.

First, when the fan 300 is rotated by receiving the driving force by the fan motor 400 constituting the vacuum cleaner, the suction inlet body 20 constituting the vacuum cleaner by the suction force generated by the rotation of the fan 300. Various foreign substances in the room are sucked from the suction port (not shown) of the room, and the first air suction flow path 120 of the primary cyclone dust collector 100 is sequentially passed through the extension pipe 30 and the suction hose 40. Flows into.

Various foreign substances introduced in this way are introduced into the primary dust collecting container 110 by the inflow force and the suction force transmitted through the first air discharge passage 130.

As such, the foreign material introduced into the primary dust collector 110 and foreign matters having a relatively large volume among various foreign substances are collected in the primary dust collector 110, and each of the first air discharge passage 130 is formed. The fine foreign matter and air having a smaller size than the diameter of the discharge hole 131 are discharged into the secondary cyclone dust collector 200.

In addition, the air and fine dust discharged to the secondary cyclone dust collector 200 through the first air discharge passage 130 as described above is sucked through the second air suction passage 250 of the secondary cyclone dust collector 200. In order to perform the cyclone movement in the process introduced into the secondary cyclone body (210).

This is possible because the second air intake passage 250 is connected in a state in which it extends along the circumferential surface of the secondary cyclone body 210.

Accordingly, air and fine dust introduced into the secondary cyclone body 210 through the second air suction flow path 250 by the suction force transmitted through the second air discharge flow path 220 perform a cyclone movement. Separation will be made.

In addition, the fine dust separated from the air as described above is discharged to the second dust collecting container 230 through the foreign matter discharge passage 240 in the process of flowing on the inner wall surface of the secondary cyclone body 210, the fine dust The separated air hits the expansion part 260 formed in the secondary cyclone body 210 and is discharged to the side space where the fan 300 and the fan motor 400 are located through the second air discharge passage 220.

7 to 10 illustrate a multiple cyclone vacuum cleaner according to a second embodiment of the present invention.

That is, in the second embodiment according to the present invention, a second dust discharge passage 220 constituting the secondary cyclone dust collector 200 and a separate dust collecting space between the space in which the fan 300 and the fan motor 400 are located. A filter structure 500 having a space is installed to be detachable from the cleaner body 10, and the filter structure 500 is equipped with a dust collecting filter 510 to add a structure configured to collect fine dust in the air passing therethrough. To present.

That is, the storage unit 150 having an inner space is further formed on the upper side of the space in which the fan 300 and the fan motor 400 which are the upper surface of the intermediate body 12 of the cleaner body 10 are formed. By collecting the filter structure 500 having the dust collecting filter 510 in the payment part 150 and having a separate dust collecting space, it is possible to perform the third fine dust collecting.

This is to enable the removal of various fine foreign matters that have not been removed by the dust collecting unit using the cyclone principle by using a filter having a separate space without using the cyclone principle.

That is, it may be considered that foreign matters such as tissues and hairs having little mass thereof and foreign matters such as fine dust may be included in the air discharged through the secondary cyclone dust collecting unit 200 to the space where the fan motor 400 is mounted. This is to prevent the damage to the fan motor 400 by performing a smooth removal of the foreign matter.

At this time, the dust collecting filter 510 accommodated in the filter structure 500 is formed to form a plurality of peaks and valleys in a repeated shape so that the dust can be collected as much as possible even if the size is relatively small.

That is, by forming the contact area between the dust collecting filter 510 and the air passing therethrough as wide as possible, the contact with the air can be made as much as possible to improve the dust collecting performance.

On the other hand, the filter structure 500 as described above has an empty cylindrical shape, the bottom and one side of the body portion 520 is opened, and the body portion is selectively mounted to the opening of the body portion 520 The filter guide portion 530 that closes the site is large.

At this time, the body portion 520 is formed to form a substantially rectangular parallelepiped, and a communication hole 521 is formed on one side thereof is connected to the second air discharge passage 220 of the secondary cyclone dust collector 200. The bottom surface, which is the space side where the fan motor 400 is located, is opened, and one side thereof is opened.

In addition, the filter guide part 530 is formed such that one side thereof closes the opened side surface of the body part 520, and the dust collecting filter 510 is accommodated in the inner bottom thereof to open the body part 520. The bottom is closed.

The shape of the body portion 520 is not limited to the shape of the rectangular parallelepiped, but in order to form a polyhedron in consideration of the shape characteristics according to the mounting position of the filter structure 500 as illustrated in FIGS. 7 to 9. It does not matter.

In addition, the combination of the body portion 520 and the filter guide portion 530 is configured as a drawer type, which is configured as described above, which is the inner surface of the body portion 520 and both sides of the outer surface of the filter guide portion 530 The guide protrusions 522 may be formed on the surface to be contacted, and guide grooves 531 corresponding to the guide protrusions 522 of the body portion may be formed on both side surfaces of the filter guide part 530.

At this time, a part of the corner portion of the side surface of the upper surface of the body portion 520 constituting the filter structure 500, the one end of the filter guide portion 530 is indented to form a handle groove (523) to form a body portion ( Detachment of the filter guide unit 530 from the 520 is made easily.

Therefore, in the process of discharging the air separated dust while passing through the dual cyclone dust collector according to the present invention into the space in which the fan 300 and the fan motor 400 are located through the second air discharge passage 220. Pass through the filter structure 500 having a predetermined dust collection space, it is possible to completely remove the fine dust contained in this air during this process.

That is, the fine dust flowing in the second air discharge flow path 220 passes through the communication hole 521 of the filter structure 500 and flows into the space inside the filter structure 500, and the filter structure 500. The air and the fine dust introduced into the dust collecting filter 510 which is closing the lower part of the filter structure 500 receives the suction force continuously transmitted from the fan 300 located at the bottom of the filter structure 500. Will pass.

Therefore, the fine dust included in the air remains in the filter structure 500 in a state where dust is collected again by the dust collecting filter 510 and separated from the air, and only the clean air from which the fine dust is removed is collected. Passing through the 510 is discharged to the space in which the fan 300 and the fan motor 400 is mounted.

At this time, considering that a predetermined space is formed inside the filter structure 500, the fine dust separated from the air discharged by the dust collecting filter 510 remains in the space in the filter structure 500 The dust is collected.

As a result, even if the user does not recognize the dust collection state of the foreign matter in the secondary dust collecting container 230, it is understood that the foreign matter can be prevented from leaking into the space where the fan motor 500 is located.

That is, the user may not discharge the foreign matter collected in the secondary dust collecting container 230 of the secondary cyclone dust collecting unit 200, and the like may be fine dust exceeding the allowable dust collecting capacity of the secondary cyclone dust collecting unit 200 during the next cleaning. Even if the discharge is made, it is possible to prevent the damage of the fan motor 400 due to the fine dust by again collecting the fine dust in the predetermined fine dust collecting space formed by the filter structure 500.

On the other hand, the filter structure 500 is configured as described above should be configured so that the user can be removed from the cleaner body 10 smoothly as necessary for its clean maintenance.

Accordingly, the present invention further provides a structure in which a space in which the accommodating part 150 in the cleaner body 10 is located is opened with respect to the upper portion of the cleaner body 10 as shown in FIG. 7.

In addition, the cover part 160 is separately mounted on the surface of the upper cover 13 that is the upper portion of the accommodating part 150 to selectively open and close the space.

At this time, one end of the cover portion is coupled to the hinge 101 to the cleaner body 10, the side opposite to the hinge coupled side to enable the selective detachment to the cleaner body 10 using a structure such as a hook. .

At this time, the structure of the hook or the like is configured to integrate the handle 170 on the upper surface of the cover portion 160, and to form a locking structure such as the hook 161 on the end of the handle 170.

This, the handle 170 is configured to perform the role of the cover portion 160 opening and closing handle and the transfer handle of the cleaner body 10 for the selective detachment of the filter structure 500 at the same time additional additional handle This is to solve the structural problems caused by the manufacturing process for construction and its structural addition.

Therefore, when it is desired to discharge the fine dust collected in the filter structure 500, first, the handle 170 is removed from the cleaner body 10 to cover the cover portion 160 in which the handle 170 is integrated. By rotating, the accommodating part 150 on which the filter structure 500 is seated is opened.

Thereafter, the user discharges the fine dust collected in the filter structure 500 by removing the filter structure from the accommodating part 150 using the handle groove 523 formed on the upper surface of the filter structure 500. Done.

That is, the filter structure 500 is removed from the accommodating part 150, and then the body part 520 constituting the filter structure 500 and the filter guide part 530 are removed from each other to form a space in the body part 520. It is to discharge the various fine foreign matter collected in the phase.

At this time, as the coupling between the body portion 520 and the filter guide portion 530 constituting the filter structure 500 is configured to be a drawer type can be removed smoothly between each other.

In addition, the filter guide portion 530 is located between the upper surface of the dust collecting filter 510 and the upper end of the filter guide portion 530, as the upper surface of the filter guide portion 530 is located high from the upper surface of the dust collecting filter 510 mounted therein. Even if a predetermined space is formed in the filter guide unit 530 of the filter body 500, even if the filter guide portion 530 is removed, the external leakage of various foreign matters accumulated on the top of the dust collecting filter 510 Can be prevented.

On the other hand, by adding an additional filter other than the dust collecting filter 510 inside the filter structure 500 to perform the above-described action can be configured to achieve a more perfect dust collection.

However, it is not limited to the addition of the filter in consideration of the fact that the installation of many filters may cause a reduction in suction power, such as requiring an excessive driving force of the fan motor.

However, it can be understood that an additional filter 540 can be added to induce an increase in dust collection efficiency as shown in FIGS. 8 and 9.

In addition, the second embodiment of the present invention is not limited to the structure configured to re-collect the fine dust in the air passing through the secondary cyclone dust collector 200.

That is, a filter structure having a separate dust collecting space according to the present invention may be installed on the air flow path between the primary cyclone dust collecting portion and the secondary cyclone dust collecting portion, and the vacuum cleaner having only one cyclone dust collecting portion may be provided. The filter structure according to the present invention may be installed on the flow path of air flowing through the cyclone dust collector and into the space in which the fan motor is located.

In conclusion, the present invention is not only a useful invention that can apply the dual cyclone dust collector to a canister vacuum cleaner, but also a useful invention that can improve the user's satisfaction by removing more foreign substances. .

As described above, the present invention has the effect that the overall allowable dust collecting capacity of the dual cyclone dust collector can be greatly expanded as compared with the related art.

As a result, the size of the cyclone dust collector can be made smaller in preparation for the allowable dust collection capacity, thereby making it possible to apply it to a canister vacuum cleaner.

In addition, when the present invention is applied to the canister vacuum cleaner as described above, the dust collecting container can be smoothly detached from the cleaner body, so that the user can easily operate the foreign matter in the dust collecting container.

In addition, by further comprising a filter structure having a separate space in the vacuum cleaner using the cyclone principle, there is an effect that it is possible to achieve a complete dust collection of fine foreign matter not yet collected by the cyclone dust collector.

In other words, even though the dust collector of each cyclone dust collecting unit is not able to perform the perfect dust collection, even though fine dust is discharged to the space where the fan and the fan motor are mounted, the dust is regenerated by the filter structure having a separate dust collecting space. There is an effect to minimize the amount of fine foreign matter that can be leaked to the motor.
