Description

Scope of technical application

The present invention relates to a dust separator for a vacuum cleaner.

BACKGROUND OF THE INVENTION

A vacuum cleaner is generally a device that uses the suction force provided by a suction motor installed in a housing to suck in air including dust and to filter dust inside the housing.

Such suction vacuum cleaners are mainly divided into container vacuum cleaners that have a suction nozzle mounted separately from the housing and connected to it, and to vertical vacuum cleaners that have a suction nozzle connected to the housing.

The vacuum cleaner according to related technical solutions includes a housing and a device for separating dust mounted in the housing of the vacuum cleaner for separating dust from air. The dust separator is typically designed to separate the dust using the cyclone principle.

The characteristic of a vacuum cleaner constructed in this way can be estimated on the basis of fluctuations in its characteristic regarding dust separation. Therefore, the dust separator for vacuum cleaners is continuously improved to provide improved dust separation performance.

In addition, based on the perspectives of the use of dust separation devices by the user, such devices are needed that can be easily separated from the vacuum cleaner body and which allow easy dust removal.

Description of the invention

Technical problem

An object of the present invention is to provide a dust separation apparatus for a vacuum cleaner that has improved dust separation properties.

Another objective of the present invention is to provide a dust separation device for a vacuum cleaner having a dust container with a simplified configuration, allowing the user to easily remove dust.

Another objective of the present invention is to provide a device for separating dust intended for a vacuum cleaner, which will allow the user to exert minimal effort to manipulate the container intended for dust.

Technical solution

In one embodiment, the dust separating apparatus for the vacuum cleaner includes: a cyclone forming one or more inlets through which air is drawn in; dust outlet through which dust separated in the cyclone is released; a dust container for collecting dust released through a dust outlet; a guiding element provided on the cyclone and intended to give direction when releasing dust separated by air flow in the cyclone.

In yet another embodiment, a device for separating dust in a vacuum cleaner includes: a separator for separating dust from air sucked through a plurality of air inlets through a cyclone air stream; a dust outlet for discharging dust separated in a separator; a guiding element provided inside the dust separator and around the dust outlet to give direction in the discharge of dust.

In yet another embodiment, a device for separating dust in a vacuum cleaner includes: a dust separator forming a plurality of inlets; a guiding element separating the inside of the dust separator to give direction in the discharge of dust; a dust outlet through which dust separated in the separator is discharged; a container for collecting dust released through the dust outlet.

In yet another embodiment, the apparatus for separating dust in a vacuum cleaner includes: a dust separator assembly formed in conjunction with a first cyclone associated with a second cyclone; a container for collecting dust separated in the dust separation unit, wherein a first surface perpendicular to the axis of the air flow in the first cyclone is connected to a second surface perpendicular to the axis of the air flow in the second cyclone, the first and second surfaces giving direction when the separated dust is released.

Beneficial effects

An advantage according to the embodiments of the present invention is that due to the large number of inlets formed in the cyclone and the large number of air flows formed in the cyclone, the volume of the air stream increases and the loss of air flow decreases, which improves the performance regarding dust separation.

In addition, inlets are formed on each side of the cyclone, and a dust outlet is formed in the center of the cyclone, so that a strong air flow is created in the central part of the cyclone to allow easy dust discharge.

In addition, since the dust outlet is formed tangentially to the cyclone, the dust can be discharged in the same direction in which it rotates. Therefore, not only dust of increased density, but also dust of reduced density can be easily released from the cyclone.

Further, since the cap element is detachably connected to the cyclone, with the cap element separated from the cyclone, the user can easily clean the inside of the cyclone and the filter element.

In addition, since a guide element is provided for the dust separator, the separated dust can be easily discharged. Accordingly, clogging with dust of the outlet or filter element can be prevented, which will facilitate the passage of air flow, so that the characteristic regarding dust separation will be improved.

Further, when the separating cyclones are connected in an axial direction, the size of the dust particles in the dust separation unit can be reduced.

In addition, since the container that is designed to accumulate dust is made in the form of a component separate from the dust separator, the user can remove dust by separating only the container, which improves user convenience with respect to handling the dust container.

Further, since no dust separation structure is installed inside the dust container, the dust container structure is simplified, while the weight of the container is minimized, which improves user convenience.

In addition to the above, by simplifying the internal structure of the dust container, it is easy to remove dust accumulated in the container.

The method of carrying out the invention

Next, with reference to the drawings will be presented a detailed description of design options according to the present invention.

1 and 2 are perspective views schematically showing the structure of a dust separating apparatus for a vacuum cleaner and configured according to a first embodiment of the present invention, and FIG. 3 is an exploded perspective view of a dust separating apparatus according to FIG. 1 and 2.

As shown in FIGS. 1-3, a dust separation device 1 for a vacuum cleaner and made according to the presented design options includes a dust separation unit 10 that separates the dust from the intake air, a container 20 for collecting dust separated node 10, a suction guide 30 that directs the flow of dust-containing air to the dust separation unit 10, and a distribution unit 40 to distribute air in the suction guide 30 to the separation unit 10 I dust.

More specifically, the air drawn in through the suction nozzle (not shown) flows to the suction guide 30. A guide 30 is provided inside the vacuum cleaner and is located under the dust container 20. The guide 30 has a distribution unit 40 connected thereto.

The assembly 10 for separating dust separates the dust from the air supplied from the distribution unit 40. In the assembly 10, the principle of a cyclone is used to separate the dust from the air, and this assembly for this purpose includes a cyclone 110.

The cyclone axis 110 extends horizontally. Thus, the air inside the cyclone 110 rotates in the vertical direction.

To suck in air, a pair of inlets 120 is formed on cyclone 110 (one on each side). A pair of inlets 120 may be formed in a tangential direction with respect to the cyclone 110 to create an air flow within the cyclone 110. A pair of inlets 120 provides suction channels for air entering the cyclone 110.

A pair of inlets 120 is connected, one on each side of the distribution unit 40. Therefore, air that flows through the suction guide 30 branches off on each side of the distribution unit 40 and branched air rises along the respective inlets 120 for suction into the cyclone 110.

A dust outlet 130 that releases dust separated inside the cyclone 110 is formed at the center of the cyclone 110.

Accordingly, the dust separated from the air drawn in through each inlet 120 on each side of the cyclone 110 moves to the center of the cyclone 110. Next, the dust that flows to the center of the cyclone passes through the dust outlet 130 and will be released to the dust container 20.

In this case, the dust outlet 130 is formed tangentially with respect to the cyclone 110 to allow easy dust discharge. Thus, the dust separated in the cyclone 110 will be released tangentially with respect to the cyclone 110, that is, in the same direction in which the dust rotates, which provides easy release from the cyclone 110 not only dust with increased density, but also dust with reduced density.

Since it will be possible to easily release dust with a reduced density, dust having a reduced density will accumulate to a lesser extent on the filter element (described below), which facilitates the passage of air flow and improves the performance regarding dust separation.

In addition, bends 140 are formed, one on each side of the cyclone 110, for discharging air separated from dust in the cyclone 110. The air discharged through the bends 140 converges in the converging passage 142 and enters the vacuum cleaner body (not shown).

A container 20 stores dust separated in a dust separation unit 10. Since the dust container 20 is mounted on the cleaner body, this container 20 communicates with the dust separation unit 10.

More specifically, when the dust container 20 is mounted on the cleaner body, this container 20 will be located under the dust separation unit 10. Thus, a dust inlet 210 is formed in the upper side of the container 20. In addition, the dust outlet 130 extends downward from the cyclone 110.

Accordingly, the dust separated in the cyclone 110 passes down along the dust outlet 130 and the separated dust can easily enter the container 20.

To release dust accumulated in the container 20, a cap element 220 is connected at its bottom. The cap element 220 may be pivotally connected to the container 20, but may also be detachably connected to it. The method for connecting the lid member 220 in this embodiment is not limited to any particular methods.

Thus, the dust container 20 is designed as a separate component with respect to the dust separation unit 10 and is designed to selectively communicate with the node 10. Accordingly, to remove the dust accumulated in the container 20 outward, the user can only separate the container 20 from the vacuum cleaner body.

Since the structure for separating dust is not created inside the container 20, the structure of the container 20 is simplified and the weight of the container 20 can be minimized.

By minimizing the weight of the container 20, the user can easily carry and manipulate the container 20, and since the inner structure of the dust container 20 is simple, the dust can be easily removed to the outside and the user can easily clean the inside of the container 20.

Below will be a more detailed description of the device for separating dust.

Figure 4 presents a view in section along the line aa shown in figure 1, and figure 5 presents a view in section along the line bb shown in figure 1.

As shown in FIGS. 4 and 5, the cyclone 110 includes a housing 111 for creating air flow and a pair of sides 115, each of which forms one of the sides of the housing 111. The sides 115 are parallel and facing each other.

An inlet 120 is appropriately formed on each side of the housing 111. Each inlet 120 is formed tangentially with respect to the cyclone 110. Thus, the air drawn in through each inlet 120 forms one of two air flows inside the cyclone 110. Air flows in the cyclone circulate along the inner the surface of the housing 111.

Therefore, when a pair of cyclone air flows is created within a single space, the volume of the air flow will be increased, the loss of air flow will be reduced, and the separation characteristic can be improved.

In addition, when a pair of cyclone air streams is created within a single space, the cyclone can be formed smaller than in the case of one cyclone air stream created in one space.

In this case, even if the cyclone 110 is formed reduced, the centrifugal force created by the inlets 120 will be greater than in related technical solutions, which allows to increase the characteristic regarding dust separation.

Further, when a pair of cyclone air streams is created in a single space, the same level of dust separation performance can be provided as in the case in which the air passes through a large number of dust separation units. Thus, additional nodes are not required to separate the dust from the air discharged from the dust separation unit. However, in the present embodiment, additional dust separating units may be provided.

In addition, when a pair of cyclone air streams is created, one of them on each side of the cyclone 110, and the cyclone air streams flow toward the center, the air flow in the center increases. Therefore, a stronger airflow will be created in the center of the cyclone 110 than at the sides of the inlets 120.

Thus, when a pair of airflows converges in the center of the cyclone 110, the force of the airflow will be greater than when a single cyclone airflow will be created in a single space, which allows to increase the characteristic regarding dust separation.

Dust that moves toward the center of the cyclone 110 can be discharged through the dust outlet 130 to the container 20 by strong airflow into the cyclone, so that the dust discharge characteristic can be improved.

Hair and other contaminants can easily stick to the inlet or to the inside of the dust outlet 130 by static electricity. However, since a strong cyclone airflow will be created at the dust outlet 130 in the present embodiment, the hair and other contaminants do not adhere to the outlet 130 and can be easily released to the dust container 20.

The outlet 116 is formed so that it passes through each side 115 to release air, from which dust is separated in the cyclone 110.

In addition, for filtering the exhaust air, a filter element 150 is connected to each outlet 116. More specifically, the filter element 150 is provided with a cylindrical fastening means 152 attached to the inside of the cyclone 110 and with a conical filter 154 extending from the fastening means 152 for filtering the air. A large number of holes 156 are also formed in the filter 154 for air to pass through them.

Accordingly, air separated from dust in the cyclone 110 passes through a large number of openings 156 and will be released from the cyclone 110 through outlets 116.

In this case, the fastening means 152 does not contain through holes formed therein, so that the air drawn in through the inlet 120 will not be immediately released, but can smoothly circulate inside the cyclone 110.

That is, by using the suction air circulation fixing means 152, a direction can be given to create a smooth air flow inside the cyclone 110, which improves the dust separation characteristic.

The length (L1) between the pair of filter elements 150 mounted inside the cyclone may be greater than the width (L2) of the dust outlet 130.

More specifically, the air flows generated in the cyclone 110 converge in the center of the cyclone 110, as described above, and dust separated from the air by the air flow in the cyclone will be discharged through the dust outlet 130.

In this case, when the length (L1) between the pair of filter elements 150 is less than the width (L2) of the dust outlet 130, contaminants such as hair and thin paper will not be released through the dust outlet 130 and may stick to the filter element 150 or get stuck inside the holes 156. At the same time, air will not be able to freely pass through the filter element 150, which leads to a decrease in the suction force.

Accordingly, in the illustrated embodiments, a length (L1) is provided between the pair of filter elements 150, which is greater than the width (L2) of the dust outlet 130, so that contaminants such as hair and thin paper can be completely discharged through the dust outlet 130.

As described above with respect to the presented embodiment, air is sucked into the cyclone 110 through a large number of inlets 120, and air separated from dust in the cyclone 110 will be released from the cyclone 110 through a large number of outlets 116.

Thus, air whose suction into the cyclone 110 takes place through the respective inlets 120 will be discharged through the respective outlets 116 to allow free air exit.

Therefore, when air can be easily discharged from the cyclone 110, the suction force will actually be increased and the air flow inside the cyclone 110 will be smoothly generated.

In addition, even when dust accumulates on the filter element so that air cannot flow freely, it can be discharged through another filter element, thereby preventing a sharp loss of suction force.

Inside the cyclone 110, a pair of guides 170 are formed to prevent dust separated by the airflow in the cyclone from being moved to the bends 116.

More specifically, the guide elements 170 are formed along the inner periphery of the cyclone 110 in the form of continuous curves. The guide elements 170 extend to a predetermined length from the inner periphery of the cyclones 110 to their axes.

In addition, the guide elements 170 extend from the inner periphery of the cyclones 110 to the dust outlet 130. That is, the guide elements 170 have a cross section that is formed with a given slope. Accordingly, one end 171 of each of the guide elements 170 has a diameter larger than the diameter of its other end 172. More precisely, the guide elements 170 are formed so that they have diameters that gradually taper from the bends 116 to the dust branch 130.

In this case, the cyclone air flow formed at the inlet 120 moves to the dust outlet 130 along the inner periphery of the cyclone 110. When the diameters of the guide elements 170 gradually become smaller to the dust outlet 130, the cyclone air flows will be directed by the inner inclined surfaces 173 of the guide elements 170 so that they flow freely to the dust outlet 130.

On the contrary, when the air flows of the cyclone move to the other ends 172 of the guide elements 170, these flows pass between the outer inclined surfaces 174 of the guide elements 170 and the inner periphery of the cyclone 110, while their passage to the bends 116 will be prevented.

When the airflow of the cyclone to the outlet 116 by the guide members 170 is similarly prevented, the movement of the separated dust to the branches 116 is prevented. Therefore, the separated dust circulates between each guide member 170 and can be completely discharged through the dust outlet 130.

When the separated dust is prevented from moving to the outlets 116, clogging of the openings 156 of the filter element 150 with the separated dust (mainly increased dirt, such as tissue paper) can be prevented and therefore a reduction in air suction power can also be prevented.

In addition, since the diameter of the flow guide 170 gradually decreases toward the dust outlet 130, the force of the air flows of the cyclone converging at the dust outlet 130 can be increased, which allows easy dust discharge.

Thus, each guide member 170 in the illustrated embodiment can direct the airflow of the cyclone so as to smoothly pass from the taps 116 to the dust tapping 130, and allows the cyclone to flow between the respective guide members 170 when the cyclone flows tap 130 for dust.

In this case, in order to allow easy release of dust passing along the outer inclined surface 174 of each guide member 170, one end 172 of each guide member 170 may be located within the width of the dust outlet 130. That is, at least a portion of the dust outlet 130 is located between the guide elements 170.

When one end 172 of each guide member 170, as described above, is within the width of the dust outlet 130, dust on the outer inclined surfaces 174 of each guide member 170 will not be discharged through the outlet 130, and thus its continuous circulation along the guide elements can be prevented. 170.

An opening 112 is formed on the cyclone body 111 of the cyclone 110 to allow for replacement and cleaning of the filter element 150. The opening 112 is opened and closed by the lid element 160. A sealing element 114 is provided in the connection area of the hole 112 and the lid element 160.

In this case, the inner surface of the lid member 160 may be formed so that it has the same curvature as the inner periphery of the housing 111 when the lid member 160 is connected to the housing 111. Accordingly, changes in the airflow of the cyclone due to the presence of the lid member 160 inside the cyclone 110 can be prevented, and the uniformity of air flow in the cyclone can be maintained.

In addition, since the lid member 160 is detachably connected to the cyclone 110, the user can separate the lid member 160 to easily replace the filter elements 150 and still easily clean the inside of the cyclone 110 and the filter elements 150.

A dust accumulation compartment 202 is formed inside the container 20, and a dust supply 210 is formed at the top of the container 20. In addition, a sealing member 212 is provided on the dust inlet 210 for sealing the contact area between the dust inlet 210 and the dust outlet 130. In this case, a sealing member 212 may also be provided at the dust outlet 130.

Below will be described the operation of the device for separating dust.

6 and 7 are sectional views showing an air flow inside a dust separation device according to a first embodiment, and FIG. 6 is a view showing a cross-sectional air flow along line AA in FIG. 1 , and Fig.7 is a view showing the air flow in section along the line BB in Fig.1

As shown in FIGS. 6 and 7, when a suction force is generated by a vacuum cleaner, air including dust flows along the suction guide 30. Air passing through the suction guide 30 flows to the distribution unit 40 and will be distributed to each inlet 120 via the distribution unit 40. Further, air including dust passes through each inlet 120 and will be suctioned in a tangential direction on each side cyclone 110.

The intake air rotates along the inner surface of the cyclone 110 to move along the guide elements 170 and converges in the center of the cyclone 110, and during this process, air and dust will be exposed to different centrifugal forces due to their difference in weight, so that they separate.

The separated dust (represented by dashed lines) will be discharged from the center of the cyclone 110 through the dust outlet 130, while the released dust passes through the outlet 130 into the dust container 20.

On the contrary, the air (represented by solid lines), separated from the dust, will be filtered by filter elements 150, after which it passes through the bends 116 and will be released from the cyclone 110. The released air flows through the corresponding bends 140 for air, converges at the converging channel 142 and comes into the vacuum cleaner case.

Fig. 8 is a perspective view of a dust separation unit according to a second embodiment of the present invention, and Fig. 9 is a sectional view taken along line CC of Fig. 8.

The presented embodiment of the construction is similar to the first embodiment in all other respects, with the exception of the internal structure of the cyclone. Therefore, only the description of the differing parts of the presented embodiment will be provided.

As shown in FIGS. 8 and 9, the dust separation unit 70 according to the present embodiment includes a cyclone 710. A partition 720 is installed in the center of the inner part of the cyclone 710. The partition 720 is integral with the inner periphery of the cyclone 710. Accordingly, the cyclone 710 is centered by a partition 720 into a first cyclone 711 and a second cyclone 712.

In addition, air currents are created within the cyclone 710 on each side of the partition 720. The baffle 720 is perpendicular to the axes of the air flow of the cyclone.

To exhaust dust separated in the first cyclone 711 and in the second cyclone 712, an outlet 731 is formed in the cyclone 710. The partition 720 also separates the outlet 731 into the left part and the right part. Accordingly, the outlet 731 can be divided into a first outlet 732 and a second outlet 733, separated by a partition 720.

That is, the dust separated in the respective cyclones 711 and 712 will be released from the cyclones 711 and 712, respectively, through the first outlet 732 and the second outlet 733. The released dust accumulates at the outlet 730 and enters the container.

Next, a description will be given of the air flow inside the dust separation unit according to the present embodiment. Air, including dust, through suction enters the first and second cyclones 711 and 712.

Further, the air drawn into each cyclone 711 and 712 is circulated along the inner periphery of each cyclone 711 and 712 so that it is subjected to a dust separation process. The dust separated in each cyclone 711 and 712 moves to the partition 720 and passes through each branch 732 and 733 to the dust outlet 730. More specifically, the dust separated in each cyclone 711 and 712 converges in the dust outlet 730 and then moves toward the dust container.

In this case, dust emission in the first cyclone 711 is given direction through one side of the partition 720 (the right side in FIG. 9), and dust emission in the second cyclone 712 is given direction through the other side of the partition 720 (left side in FIG. 9).

Accordingly, in the description of the presented design variant, the baffle 720 may be called a guiding element, which gives direction upon the release of dust separated in each cyclone.

FIG. 10 is a perspective view of a dust separation unit according to a third embodiment of the present invention, and FIG. 11 is a sectional view taken along line D-D in FIG. 10.

The presented design option is the same as the second option, in all other respects, except that the two cyclones are connected to each other. Therefore, only the different parts of the presented embodiment will be described.

As shown in FIGS. 10 and 11, the dust separation unit 75, made according to the presented embodiment, includes a cyclone that generates air flow. The cyclone includes a first cyclone 751 and a second cyclone 752. The first and second cyclones 751 and 752 are formed with respective configurations and connected to each other.

More specifically, cyclones 751 and 752 are connected to each other in the axial direction of the air flow in the cyclones. Accordingly, the connecting surfaces of each cyclone 751 and 752 intersecting the axes of the air flows of the cyclones are pressed against each other. Each surface intersecting the axes of the cyclone's air flow gives a direction when the separated dust is released.

In addition, a connector 753 is formed on the second cyclone 752 for connecting the latter to the first cyclone 751, and a slot 755 is formed in the first cyclone 751 for receiving the connector 753.

The connector 753 has a connecting protrusion 754 formed thereon for connecting to the first cyclone 751, and the socket 755 has a connecting protrusion 756 formed on it for connecting to the connector. Of course, the recesses into which the connecting protrusions 754 and 756 are inserted are formed in the connector 753 and in the socket 755.

The cyclones 751 and 752 have a first dust outlet 771 and a second dust outlet 772 formed therein.

In addition, an extension 773 of the first dust outlet and an extension 774 of the second dust outlet are formed, which extend respectively from the outside of the cyclones 771 and 772 to allow dust to escape from the branches 771 and 772 and enter it into the dust container.

When the first cyclone 751 and the second cyclone 752 are connected to each other, the extensions 773 and 774 of the dust taps will be pressed against each other.

In addition, each cyclone 751 and 752 has a lid member 761 and 762, respectively, which are detachably connected thereto to allow the user to clean the inside of the cyclones 751 and 752.
