Technical Field

The present disclosure relates to a cleaner.

Background

A cleaner is a device that performs cleaning by suctioning and wiping dust or foreign substances on a surface to be cleaned.

The cleaners may be classified into a manual cleaner that a user personally moves to clean and a robot cleaner that automatically moves to clean.

The manual cleaners may be classified into a canister type cleaner, an upright type cleaner, a hand type cleaner, and a stick type cleaner (stick cleaner) according to types.

A centrifugal separation apparatus is disclosed in korean patent laid-open publication No. 10-2009-0026209, which is a prior art document. The centrifugal separation apparatus forms part of a hand-held cleaner.

The centrifugal separation apparatus includes a cyclone separator having a wall and a base enclosing one end of the cyclone separator.

A cover is arranged in the cyclone separator. The cover includes a cylindrical wall having a plurality of through holes and an inner wall disposed inside the cylindrical wall.

The centrifugal separation apparatus further comprises an additional cyclone assembly and the additional cyclone assembly comprises a cone opening. A tapered opening is disposed through the inner wall of the cap and communicates with the passage defined by the inner wall.

Further, a dust collector is arranged below the passage. The interior of the dust collector is surrounded by the base.

The additional cyclone assembly separates dust from the air. In this case, the dust separated by the additional cyclone assembly often blocks the cone opening. In this case, the cone opening must be cleaned.

However, according to the related art, even if the base is rotated to open the inside of the dust container, it is difficult to allow a user to access the cone-shaped opening because the cone-shaped opening is disposed inside the cover disposed at the upper portion of the dust container.

Advantageous effects

According to the proposed embodiment, the dust separating module including the second cyclone unit may be separated from the main body to easily clean the second cyclone unit.

In addition, since the filter unit surrounding the second cyclone unit is separated from the main body together with the second cyclone unit, the filter unit can be easily cleaned.

In addition, when the dust separating module is separated from the main body, since there is no structure in the dust container, the inner circumferential surface of the dust container can be easily cleaned.

In addition, since the sealing member is provided on the discharge guide or the dust separation module, a sealed state of the contact portion between the discharge guide and the dust separation module may be maintained in a state where the dust separation module is mounted on the main body.

In particular, since the dust separation module is coupled to the main body by the rotation of the dust separation module in a state where the sealing member is pressed, the sealing performance may be further improved.

In addition, when the dust separation module is coupled to the main body in a state in which the sealing member is pressed, a frictional force between the first coupling portion of the discharge guide provided for coupling and the first groove may be increased to stably maintain the coupled state.

In addition, since the upper end of the filter unit contacts the connection module and the lower end of the filter unit is seated on the storage unit, it may not be necessary to provide a separate fixing unit to fix the position of the filter unit, thereby achieving a simplified structure.

Referring to fig. 1 to 5, a cleaner 1 according to an embodiment may include a main body 2.

The cleaner 1 may further include a suction inlet 5 coupled to a front portion of the main body 2. The suction inlet 5 may guide air containing dust into the main body 2. A suction pipe or nozzle (not shown) is connected to the suction inlet 5.

The cleaner 1 may further include a handle unit 3 connected to the main body 2. The handle unit 3 may be opposed to the suction inlet 5 on the main body 2.

That is, the main body 2 may be disposed between the suction inlet 5 and the handle unit 3.

The body 2 may include a first body 10 and a second body 12 on the first body 10. The first body 10 and the second body 12 may be directly coupled or may be indirectly coupled via an intermediate member.

The first body 10 and the second body 12 may be formed in a cylindrical shape, but are not limited thereto.

The first body 10 and the second body 12 are open at the top and bottom, respectively. That is, the bodies 10 and 12 may have top and bottom openings, respectively.

The suction inlet 5 may be coupled to the main body 2 such that the centre of the suction inlet 5 is located substantially at the boundary between the first and second bodies 10, 12.

The main body 2 may further include a dust separating unit that separates dust from air drawn in through the suction inlet 5.

The dust separating unit may include a first cyclone separator unit 110, and the first cyclone separator unit 110 may separate dust using, for example, a cyclone flow. In this configuration, the first body 10 includes the first cyclone unit 110.

The air and dust sucked through the suction inlet 5 spirally flow along the inside of the first cyclone unit 110.

The axis of the cyclone flow in the first cyclone unit 110 may extend vertically.

The dust separating unit may further include a dust separating module 700, in which dust is separated again from the air primarily separated from the dust in the first cyclone unit 110 in the dust separating module 700.

The dust separation module 700 may further include a second cyclone unit 730. Here, the second cyclone unit 730 may be disposed in the first cyclone unit 110 such that the size of the dust separating unit is minimized.

The first body 10 may further include a dust container 120, the dust container 120 storing dust separated in each of the cyclone units 110 and 730. For example, the upper portion of the first body 10 may be the first cyclone unit 110, and the lower portion of the first body 10 may be the dust container 120.

The main body 2 may further include a main body cover 16 opening and closing the lower side of the dust container 120. The main body cover 16 may open and close the dust container 120 by a rotating operation thereof. The dust container 120 may be provided with a button 18 for manipulating to allow the body cover 16 to rotate.

The hinge 16a of the main body cover 16 may be coupled to a hinge coupling part 620 provided on the battery case 60.

At least a portion of the second cyclone unit 730 may be disposed in the first body 10.

The dust separation module 700 may guide the air separated from the dust in the first cyclone unit 110 to the second cyclone unit 730.

In addition, the dust separation module 700 may filter the air flowing from the first cyclone unit 110 to the second cyclone unit 730. To this end, the dust separation module 700 may further include a filter unit 710.

In addition, the dust separation module 700 may store dust separated in the second cyclone unit 730. To this end, the dust separation module 700 may further include a storage unit 770.

The filter unit 710 may surround the second cyclone unit 730.

The storage unit 770 may contact the top surface of the body cover 16. The storage unit 770 may partition the inner space of the first body 10 into: a first dust storage part 121 storing dust separated in the first cyclone unit 110; and a second storage part 123 storing dust separated in the second cyclone unit 730.

The space defined by the storage unit 770 may be the second dust storage part 123, and the space between the storage unit 770 and the first body 10 may be the first dust storage part 121.

The main body cover 16 may open/close both the first dust storage part 121 and the second dust storage part 123.

The cleaner 1 may further include a suction motor 20 for generating a suction force and a battery 40 for supplying power to the suction motor 20.

The suction motor 20 may be disposed in the second body 12. At least a portion of the suction motor 20 may be disposed above the dust separating unit. Thus, the suction motor 20 is disposed above the first body 10.

The suction motor 20 may communicate with an air outlet of the second cyclone unit 730.

To this end, the main body 2 may further include a discharge guide 28 communicating with the second cyclone unit 730 and a guide 22 communicating with the discharge guide 28.

The discharge guide 28 guides the air discharged from the second cyclone unit 730 to the suction motor 20.

For example, the discharge guide 28 is disposed on the second cyclone unit 730, and the guide flow 22 is disposed above the discharge guide 28. Further, for example, the dust separation module 700 may be detachably coupled to the discharge guide 28.

The longitudinal axis a1 of the suction portion 5 may pass through the discharge guide 28.

Further, at least a portion of the suction motor 20 is located inside the baffle 22.

Accordingly, the axis of the cyclone flow in the first cyclone unit 110 may pass through the suction motor 20.

When the suction motor 20 is disposed above the second cyclone unit 730, air discharged from the second cyclone unit 730 may directly flow to the suction motor 20, so that a passage between the second cyclone unit 730 and the suction motor 20 may be minimized.

The suction motor 20 may include a rotating impeller 200. The impeller 200 may be mounted on a shaft 202. The shaft 202 is arranged vertically.

The extension line of the shaft 202 (which may be considered as the rotation axis of the impeller 200) may pass through the first body 10. The rotational axis of the impeller 200 and the axis of the cyclone flow in the first cyclone unit 110 may be on the same line.

According to the present embodiment, there are the following advantages: the path through which the air discharged from the dust separating unit (i.e., the air discharged upward from the second cyclone unit 730) flows to the suction motor 20 may be reduced, and the change in the direction of the air may be reduced, and thus the loss of the air flow may be reduced.

Because the air flow loss is reduced, the suction force may be increased and the life of the battery 40 for powering the suction motor 20 may be increased.

The cleaner 1 may further include a motor housing accommodating the suction motor 20.

The motor housing may include: an upper motor case 26 covering a part of an upper side of the suction motor 20; and a lower motor case 27 covering a portion of the lower side of the suction motor 20. The suction motor 20 may be accommodated in each of the motor housings 26 and 27, and the baffle 22 may be disposed to surround the upper motor housing 26.

A portion of the motor housing may be disposed in the discharge guide 28. For example, at least a portion of the lower motor housing 27 may be disposed in the discharge guide 28. That is, the discharge guide 28 may surround the lower motor housing 27.

The outer surface of the lower motor case 27 may be spaced apart from the discharge guide 28 to define a passage 282a for air to flow between the outer surface of the lower motor case 27 and the discharge guide 28.

The discharge guide 28 may include a lower opening 282. The air discharged from the second cyclone unit 730 may pass through the lower opening 282.

At least a portion of the baffle 22 may be spaced apart from the upper motor housing 26. Further, at least a portion of the baffle 22 may be spaced apart from the second body 12.

Thus, a first air passage 232 is defined by the inside of the baffle 22 and the outside of the upper motor housing 26, and a second air passage 234 is defined by the outside of the baffle 22 and the inside of the second body 12.

The air discharged from the second cyclone unit 730 flows to the suction motor 20 via the first air passage 232, and the air discharged from the suction motor 20 flows through the second air passage 234 and is then discharged to the outside. Therefore, the second air passage 234 serves as an exhaust passage.

The handle unit 3 may include a handle 30 for a user to grip and a battery case 60 under the handle 30.

The handle 30 may be disposed behind the suction motor 20.

With respect to the direction, with respect to the suction motor 20 in the cleaner 1, the direction in which the suction inlet 5 is located is a forward direction, and the direction in which the handle 30 is located is a rearward direction.

The battery 40 may be disposed at the rear of the first body 10. Therefore, the suction motor 20 and the battery 40 may be arranged not to vertically overlap each other, and may be arranged at different heights.

According to this embodiment, since the heavy suction motor 20 is disposed in front of the handle 30 and the heavy battery 40 is disposed behind the handle 30, the weight can be uniformly distributed throughout the cleaner 1. It is possible to prevent the user's wrist from being injured when the user cleans with the handle 30 in his hand. That is, since heavy components are distributed at the front and rear of the cleaner 1 and at different heights, it is possible to prevent the center of gravity of the cleaner 1 from being concentrated on either side.

Because the battery 40 is disposed below the handle 30 and the suction motor 20 is disposed in front of the handle 30, there are no components above the handle 30. That is, the top of the handle 30 forms a partial appearance of the top of the cleaner 1.

Therefore, when the user cleans with the handle 30 in his hand, any parts of the cleaner 1 can be prevented from contacting the user's arm.

The handle 30 may include: a first extension 310 extending vertically to be held by a user; and a second extension 320 extending above the first extension 310 toward the suction motor 20. The second extension 320 may extend at least partially horizontally.

In this embodiment, the first extension 310, which is a portion that can be gripped by the user (a portion that can be contacted by the palm of the user), may be referred to as a grip portion.

The first extension 310 may have a stopper 312 formed thereon, the stopper 312 being used to prevent a hand of a user holding the first extension 310 from moving in a longitudinal direction (vertical direction of fig. 2) of the first extension 310. The stopper 312 may extend from the first extension 310 toward the suction inlet 5.

The stopper 312 is spaced apart from the second extension 320. Thus, assume that a user holds the first extension 310 with some fingers above the stop 312 and other fingers below the stop 312.

For example, the stop 312 may be located between the index finger and the middle finger.

According to this arrangement, the longitudinal axis a1 of the suction inlet 5 may pass through the wrist of the user when the user grips the first extension 310.

When longitudinal axis a1 of suction inlet 5 passes through the wrist of the user and the arm of the user is extended, longitudinal axis a1 of suction inlet 5 may be substantially aligned with the extended arm of the user. Therefore, the following advantages are provided in this state: the user pushes and pulls the cleaner 1 with minimal force with the handle 30 in his hand.

The handle 30 may include an operation unit 326. For example, the operation unit 326 may be disposed on an inclined surface of the second extension 320. A control command of the suction motor 20 may be input via the operation unit 326. For example, a command to turn on/off the suction motor may be input via the operation unit 326. Further, the intensity of the suction force of the suction motor 20 that has been turned on via the operation unit 326 can be controlled.

The operation unit 326 may be disposed to face the user. The operating unit 326 may be opposed to the stopper 312 with the handle 30 therebetween.

The operating unit 326 may be positioned at a position higher than the stopper 312. Therefore, the user can easily operate the operation unit 326 with the first extension 310 in his hand with his thumb.

Further, since the operation unit 390 is located outside the first extension 310, when the user cleans with the first extension 310 in his hand, the operation unit 390 can be prevented from being accidentally operated.

A display unit 322 for showing an operation state may be disposed on the second extension 320. The display unit 320 may be disposed, for example, on top of the second extension 320. Accordingly, the user can easily check the display unit 320 on the top of the second extension 320 while cleaning.

Although not limited, the display unit 322 may include a plurality of light emitting devices. The light emitting devices may be spaced apart from each other in a longitudinal direction of the second extension 320. For example, the display 322 may display the remaining capacity of the battery 40 and the strength of the suction motor.

The battery case 60 may be disposed under the first extension 310 and integrally formed with the first extension 310.

The battery 40 may be removably received in the battery housing 60.

For example, the battery 40 may be inserted into the battery case 60 from below the battery case 60.

The rear side of the battery case 60 and the rear side of the first extension 310 may form a continuous surface. Thus, the battery case 60 and the first extension 310 may be shown as a single unit.

When the battery 40 is inserted into the battery case 60, the bottom of the battery 40 may be exposed to the outside. Therefore, when the cleaner 1 is placed on the floor, the battery 40 can be in contact with the floor.

According to this structure, there is an advantage that the battery 40 can be directly separated from the battery case 60.

Further, since the bottom of the battery 40 is exposed to the outside, the bottom of the battery 40 can be in direct contact with the air outside the cleaner 1, and thus the battery 40 can be cooled more effectively.

Referring to fig. 3, the cleaner 1 may further include a filter unit 50, the filter unit 50 having an air outlet 522 for discharging air passing through the suction motor 20. For example, the air outlet 522 may include a plurality of openings, and the openings may be circumferentially arranged. Thus, the air outlets 522 may be arranged in an annular shape.

The filter unit 50 may be detachably coupled to the top of the main body 2.

When the filter unit 50 is combined with the main body 2, a portion of the filter unit 50 is located outside the second body 12. Accordingly, a portion of the filter unit 50 is inserted into the main body 2 through the open top of the main body 2, and another portion protrudes outward from the main body 2.

The height of the main body 2 may be substantially the same as the height of the handle 30. Accordingly, the filter unit 50 protrudes upward from the main body 2, so that the user can easily grip and separate the filter unit 50.

The air outlet 522 is located at an upper portion of the filter unit 50 when the filter unit 50 is combined with the main body 2. Accordingly, the air discharged from the suction motor 20 is discharged upward from the main body 2.

According to this embodiment, it is possible to prevent the air discharged from the air outlet 522 from flowing to the user while the user performs cleaning using the cleaner 1.

The main body 2 may further include a pre-filter 29 for filtering air flowing into the suction motor 20. A pre-filter 29 may be arranged inside the flow guide 22. In addition, a pre-filter 29 is disposed above the upper motor housing 26 and may surround a portion of the upper motor housing 26. That is, the upper motor housing 26 may include a filter support for supporting the pre-filter 29.

Fig. 6 is a diagram illustrating a state in which a body cover is rotated according to an embodiment. Fig. 7 and 8 are diagrams illustrating a state in which the dust separation module is separated from the main body according to an embodiment.

Referring to fig. 6 to 8, when the button 18 is manipulated to allow the body cover 16 to rotate, the body cover 16 may rotate about the hinge 16a to open the underside of the dust container 120.

When the body cover 16 opens the lower side of the dust container 120, at least the storage unit 770 of the dust separation module 700 may be exposed to the outside.

The storage unit 770 may be seated on the body cover 16 in a state where the body cover 16 closes the dust container 120. When the body cover 16 opens the dust container 120, the lower side of the storage unit 770 may be disposed close to the discharge opening 120a of the dust container 120. Here, the discharge opening 120a is a portion through which dust is discharged to empty the dust in the dust container 120.

As described above, the dust separation module 700 may be detachably connected to the main body 10 (e.g., the discharge guide 28).

Accordingly, the user can separate the dust separation module 700 downward from the main body 2 in a state of grasping the storage unit 770 of the dust separation module 700 through the discharge opening 120 a.

The dust separation module 700 may be drawn out to the outside of the main body 2 via the discharge opening 120 a.

Since the discharge guide 28 includes the lower opening 282, when the dust separation module 700 is drawn out to the outside of the main body 2, the motor housing (e.g., the lower motor housing 27) may be exposed to the outside.

Since the dust separating module 700 includes the filter unit 710 and the second cyclone unit 730, a user can easily clean the filter unit 710 and the second cyclone unit 730 when the dust separating module 700 is separated from the main body 2.

According to this embodiment, since the filter unit 710 and the second cyclone unit 730 are cleaned, it is possible to prevent the dust discharge hole of the filter unit 710 or the second cyclone unit 730 from being blocked or from being maintained in a blocked state, thereby preventing the dust separating performance from being deteriorated.

In addition, when the dust separation module 700 is separated from the main body 2, a user may easily access the inner space of the first body 10 to easily clean the inner circumferential surface of the first body 10.

At least a portion of the first body 10 may be made of a transparent material. Accordingly, in a state where the inner circumferential surface of the first body 10 is cleaned, the amount of dust stored in the first dust storage part 121 can be confirmed by the first body 10.

In this embodiment, since the user easily cleans the inner circumferential surface of the first body 10, the amount of dust stored in the first dust storage part 121 can be more accurately determined.

Fig. 9 is an exploded perspective view of a dust separation module according to an embodiment, fig. 10 is a sectional perspective view of the dust separation module according to an embodiment, and fig. 11 is a sectional view illustrating a state in which the dust separation module according to an embodiment is coupled to a discharge guide.

Referring to fig. 7 to 11, the dust separation module 700 according to this embodiment may include a filter unit 710 and a second cyclone unit 730.

In addition, the dust separation module 770 may further include a storage unit 770.

The filter unit 710 may have a cylindrical shape and open upward and downward. In addition, the filter unit 710 may include a plurality of openings through which air passes in a circumferential direction. For example, the filter unit 710 may include a mesh portion for filtering air as the air passes through.

The filter unit 710 may surround the second cyclone unit 730. Accordingly, the air filtered while passing through the filter unit 710 may flow to the second cyclone unit 730.

The second cyclone unit 730 may include a cyclone module 750 and a guide module 740 in communication with the cyclone module 750.

In addition, the dust separating module may further include a connection module 760 connecting the second cyclone unit 730 to the discharge guide 28.

The cyclone module 750 may include a plurality of cyclone bodies 752. The plurality of cyclone main bodies 752 may be integrated with each other.

Although not limited, among the plurality of cyclone main bodies 752, at least one cyclone main body may be disposed at the central portion, and the remaining cyclone main bodies may be disposed to surround the cyclone main body disposed at the central portion.

In this specification, the cyclone main body disposed at the central portion may be referred to as an inner cyclone main body, and the cyclone main body disposed to surround the inner cyclone main body may be referred to as an outer cyclone main body.

Each cyclone body 752 may include a first cyclone body 753 and a second cyclone body 754 extending downward from the first cyclone body 753.

For example, the first cyclone body 753 can have a cylindrical shape and the second cyclone body 754 can have a conical or frusto-conical shape.

The cyclone main body 752 may include a dust discharge portion 755 through which dust is discharged.

The cyclone separator module 750 may further include a guide coupling 757 coupled to the connection module 760.

The guide coupling 757 may be disposed between a portion of the plurality of outer cyclone main bodies and the inner cyclone main body.

The guide coupling part 757 may include: a receiving part 757a that receives the coupling main body 768 provided on the connection module 760; and a main body seating portion 757b on which the coupling main body 768 accommodated in the accommodating portion 757a is seated.

In a state where the coupling main body 768 is seated on the main body seating portion 757b, the main body seating portion 757b and the coupling main body 768 may be coupled to each other at a lower portion of the main body seating portion 757b by a coupling member such as a screw.

The cyclone module 750 may also include a storage unit coupling 758 that couples to the storage unit 770.

The storage unit coupling 758 may be disposed adjacent to the dust discharge portion 755 in the cyclone main body 752.

For example, the storage unit coupling 758 may be integral with the second cyclone body 754.

A coupling hook 759 may be provided on an outer circumferential surface of the storage unit coupling part 758.

The cyclone module 750 may have a guide module 740 seated thereon to guide air to each cyclone main body 752 and to guide air separated from dust in each cyclone main body to the discharge guide 28.

The guide module 740 may include a guide body 742, the guide body 742 including an air inlet 743. The guide body 742 may have a cylindrical shape with a diameter identical to that of the first cyclone body 753.

The guide module 740 may also include an air outlet 745 disposed inside the guide body 742.

The air outlet 745 may have a cylindrical shape. Further, the vertical length of the air outlet may be greater than that of the guide body 742.

For example, the upper end of the air outlet 745 may be higher than the upper end of the guide body 742, and the lower end may be lower than the lower end of the guide body 742.

Accordingly, when the guide module 740 is seated on the cyclone module 750, a portion of each air outlet 745 of the guide module 740 may be inserted into each cyclone body 752.

Further, air may flow in an axial direction of the guide body 742. A guide rib 744 having a spiral shape may be disposed between the inner circumferential surface of the guide body 742 and the air outlet 745 to guide the flow of air such that the air introduced into the guide body 742 in the axial direction flows along the inner circumferential surface of each cyclone body 752.

According to this embodiment, air flows to the guide body 742 in an axial direction to prevent the width of the guide module 740 from increasing.

In addition, since the air outlet 745 of the guide module 740 is inserted into the cyclone main body 752, a phenomenon that the air introduced into the cyclone main body 752 is directly discharged without being separated from the dust can be reduced.

The connection module 760 may include: a cover 762 covering the second cyclone unit 730 (e.g., the guide module 740); and a connection portion 761 connected to the discharge guide 28.

The cover 762 may have, for example, a circular plate shape. The connection portion 761 may extend upward from an edge of the cover 762.

The cover 762 may have a communication hole 763 communicating with the air outlet 745 of the guide module 740. The cover 762 may have the same number of communication holes 763 as the plurality of air outlets of the guide module 740.

When the cover 762 is seated on the guide module 740, the communication holes 763 of the cover 762 are aligned with the air outlets 745 of the guide module 740.

Accordingly, the air within the air outlet 745 may flow to the discharge guide 28 after passing through the communication hole 763.

A coupling body 768 coupled to the cyclone module 750 may be provided on the cover 762.

The coupling body 768 may extend downward from the cover 762. The vertical length of the coupling body 768 may be greater than the vertical length of the guide module 740 such that the coupling body 768 is coupled to the cyclone separator module 750.

The guide module 740 may further include a body guide 746 through which the coupling body 768 passes.

Accordingly, when the cover 762 is seated on the guide module 740, the coupling body 768 may pass through the body guide 746 and then be received in the receiving portion 757a of the cyclone module 750. Although not limited, the body guide 746 may have a cylindrical shape.

Accordingly, the coupling body 768 may pass through the guide module 740 from the upper side of the guide module 740 and then be received in the receiving portion 757a of the cyclone module 750.

A portion of the cover 762 may be inserted into the filter unit 710 through an upper opening of the filter unit 710. A stopper 764 for suspending the upper end of the filter unit 741 may be disposed outside the cover 762. The insertion depth of the cover 762 may be determined by the stopper 764, and the stopper 764 may be disposed at the upper end of the filter unit 710.

The discharge guide 28 may include a first coupling portion 286 to be coupled to the connection portion 761.

A portion of a lower portion of the discharge guide 28 may have a cylindrical shape, and the first coupling portion 286 may be disposed on the cylindrical portion 281.

The first coupling portion 286 may be a protrusion protruding from an outer circumferential surface of the cylindrical portion 281 to horizontally extend a predetermined length.

A lower opening 282 communicating with the communication hole 763 may be defined in a bottom surface (e.g., the cylindrical portion 281) of the discharge guide 28. For example, one lower opening 282 may be defined in the bottom surface of the discharge guide 28 to communicate with the plurality of communication holes 763. Alternatively, a plurality of lower openings may be defined in the bottom surface of the discharge guide 28. The plurality of lower openings may communicate with the plurality of through holes 763, respectively. That is, the number of the openings 282 defined in the discharge guide 28 may be equal to or less than the number of the plurality of through holes 763.

The connection portion 761 may include a second coupling portion 765 to be coupled to the discharge guide 28. The connection portion 761 may be coupled to surround the cylindrical portion 281 in the discharge guide 28.

The second coupling portion 765 may be disposed on an inner circumferential surface of the connection portion 761. The second coupling portion 765 may include: a first groove 766 extending downward from an upper end of the connection portion 761; and a second groove 767 extending in a direction crossing the first groove 766 (e.g., in a horizontal direction). That is, the second coupling portion 765 may have an "L" shape.

In this embodiment, the horizontal width of the first coupling portion 286 may be greater than the horizontal width of the first slot 766.

Since a portion of the discharge guide 28 has a cylindrical shape, the connection module 760 may be coupled to or released from the discharge guide 28 by the rotational operation of the connection module 760 by means of the second coupling portion 765 of the connection portion 761 and the first coupling portion 286 of the discharge guide 28.

In particular, the first coupling portion 286 is aligned with the first slot 766 of the second coupling portion 765 such that the connection module 760 is coupled to the discharge guide 28.

In this state, the first coupling portion 286 is inserted into the first slot 766. Accordingly, the first coupling portion 286 and the second slot 767 may be aligned with each other within the first slot 766. In this state, when the connection module 760 rotates in one direction, the first coupling part 286 may be inserted into the second groove 767 to complete the coupling between the connection module 760 and the discharge guide 28.

Here, the recessed depth of the first groove 766 may be smaller than that of the second groove 767 to increase the coupling force between the connection portion 761 and the discharge guide 28.

Further, the concave depth of the first slot 766 may be equal to or less than the protruding thickness of the first coupling portion 286.

In this case, when the first coupling part 286 disposed in the first groove 766 is moved to the second groove 767, a contact frictional force between the first coupling part 286 and the second groove 767 may be increased to allow a coupling force between the connection part 761 and the discharge guide 28 to be increased.

A slit 761a may be defined in a position of the connection portion 761 adjacent to the second groove 767. The slit 761a may be recessed downward from an upper end of the connection portion 761.

A sealing member 284 may be disposed between the discharge guide 28 and the connection module 760.

The sealing member 284 may be disposed on at least one of the discharge guide 28 and the connection module 760.

Fig. 11 shows an embodiment in which a sealing member 284 is arranged on the discharge guide 28.

The drain guide 28 may further include a sealing member coupling portion 283 to be coupled to the sealing member 284.

The sealing member coupling portion 283 may be disposed on, for example, a bottom surface of the discharge guide 28.

The sealing member 284 may have, for example, an annular shape, and the sealing member coupling portion 283 may be a groove having an annular shape.

The sealing member 284 may be seated on the cover part 762 in a state where the connection module 760 is coupled to the discharge guide 28.

The sealing member 284 may be disposed to surround the plurality of communication holes 763 in a state of being seated on the cover 762. Further, the inner diameter of the sealing member 284 may be greater than the diameter of the lower opening 282 of the discharge guide 28.

Therefore, the air passing through the communication hole 763 may be prevented from leaking between the discharge guide 28 and the connection portion 761 by the sealing member 284.

When the connection module 760 is coupled to the discharge guide 28 such that a contact force between the sealing member 284 and the cover part 762 is increased, the sealing member 284 may be pressed by the cover part 762.

According to this embodiment, the dust separation module 700 may be separated from the main body 2. In a state where the dust separation module 700 is mounted on the main body 2, the sealing between the discharge guide 28 and the dust separation module 700 may be maintained by the sealing member 284. Accordingly, the air discharged from the dust separation module 700 may be prevented from leaking to the first cyclone unit 110.

In particular, when the first coupling portion 286 of the discharge guide 28 reaches a position where the first coupling portion 286 is aligned with the second groove 767 in the first groove 766 to improve sealing performance, the cover 762 presses the sealing member 284. Further, in a state where the sealing member 284 is pressed, the dust separation module 700 may rotate to allow the first coupling part 286 to move to the second groove 767.

The storage unit 770 may support a lower portion of the filter unit 710. The storage unit 770 may include an inner body 771 and an outer body 780 surrounding the inner body 771.

The inner body 771 may include a first portion 771a defining the second dust storage 123. The diameter of the first portion 771a of the inner body 771 may be tapered downward.

As the diameter of the first portion 771a of the inner body 771 is gradually decreased downward, the first dust storage part 121 may increase the capacity within the dust container 120.

A relatively large amount of dust can be stored in the first dust storage part 121. If the capacity of the first dust storage part 121 is increased, the time taken for the dust to fill the first dust storage part 121 increases, thereby reducing the number of times of the operation of emptying the dust.

The inner body 771 may also include a second portion 773 disposed on an upper portion of the first portion 171 a.

For example, the second portion 773 of the inner body 771 may have a cylindrical shape. A portion of the lower part of the second cyclone unit 730 may be inserted into the second portion 773 of the inner body 771.

The inner body 771 may further include a hook coupling portion 774 to be coupled with the coupling hook 759. For example, the hook coupling 774 may be disposed on the second portion 773.

The hook coupling portion 774 may be a groove defined in an inner circumferential surface of the second portion of the inner body 771 or a hole passing through the second portion 773.

For example, when the storage unit coupling part 758 of the cyclone module 750 is received in the inner body 771, the coupling hook 759 may be coupled to the hook coupling part 774 to couple the second cyclone unit 730 to the storage unit 770.

The inner body 771 may further include a leakage prevention rib 775 inserted into an inner region of the storage unit coupling 758. The upper ends of the leakage preventing ribs 775 may be disposed higher than the hook coupling portions 774 to prevent air introduced into the storage unit 770 from flowing to the hook coupling portions 774.

At least one seal 778 for sealing the inner body 771 and the outer body 780 to each other may be coupled to an outer circumferential surface of the second portion 773 of the inner body 771. The seal 778 may have an annular shape. A seal-member seating groove 777 may be defined in an outer circumferential surface of the second portion 773 of the inner body 771, and a seal member 778 is seated in the seal-member seating groove 777.

Fig. 11 illustrates an embodiment in which a seal 778 is coupled to the outer peripheral surface of the inner body 771. In this case, the plurality of seals 778 may be arranged to be vertically spaced apart from each other.

At least one fixing protrusion 776 to be fixed to the outer body 780 may be disposed on an outer circumferential surface of the second portion 773 of the inner body 771.

The inner body 771 may further include a seating surface 779 on which the lower end of the filter unit 710 is seated.

For example, the seating surface 779 may be defined on the second portion 773. A portion of the outer diameter of the second portion 773 may be smaller than the inner diameter of the filter unit 710, and the other portion of the outer diameter of the second portion 773 may be larger than the inner diameter of the filter unit 710, such that the lower end of the filter unit 710 is seated on the second portion 773.

In this embodiment, the filter unit 710 may be fixed without using a separate fixing unit.

For example, in a state in which the lower end of the filter unit 710 is seated on the seating surface 779 of the storage unit 770, when the second cyclone unit 730 is coupled to the storage unit 770, the upper end of the filter unit 710 may contact the stopper 764 of the connection module 760. In this state, the vertical and horizontal movement of the filter unit 710 may be restricted.

The outer body 780 may further comprise a cover portion 781 surrounding the second portion 773 of the inner body 771 outside of the inner body 771. The cover portion 781 may have a cylindrical shape.

The cover portion 781 may have a projection coupling portion 783 disposed thereon, and at least one fixing projection 776 fixed to the projection coupling portion 783. For example, the protrusion coupling portion 783 may be a groove.

The inside of the cover portion 781 may be arranged with support ribs 782 supporting the lower portion of the second portion 773 of the inner body 771.

Fig. 12 is a transverse sectional view illustrating an air flow in the cleaner according to an embodiment, and fig. 13 is a longitudinal sectional view illustrating an air flow in the cleaner according to an embodiment.

Referring to fig. 1 to 13, air and dust sucked through the suction inlet 5 by the operation of the suction motor 20 are separated from each other while flowing along the inner circumferential surface of the first cyclone separator unit 110.

The dust separated from the air may flow downward and then be stored in the first dust storage part 121. The air separated from the dust may pass through the filter part 710 of the dust separation module 700 and then flow to the air inlet 743 of the second cyclone unit 730.

For example, the air separated from the dust in the first cyclone unit 110 may be filtered while passing through the filter part 710 and guided to the cyclone module 750 by the guide module 740 to perform the dust separating process again.

The dust separated from the air in the cyclone module 750 is discharged to flow downward via the dust discharge part 755 and then stored in the second dust storage part 123. On the other hand, the air separated from the dust in the cyclone module 750 is discharged to the discharge guide 28 via the air outlet 745.

The air discharged to the discharge guide 28 flows along the discharge guide 28 to move along the lower motor housing 27, and then rises along the first air passage 232 within the baffle 22. Further, the air of the first air passage 232 passes through the pre-filter 29.

The air passing through the pre-filter 29 passes through the suction motor 20 within the upper motor housing 26. The air flows into the suction motor 20 by means of the impeller 200 and is then discharged to the lower motor housing 27. Further, the air discharged to the lower motor case 27 flows to the second air passage 234.

In addition, the air flowing to the second air passage 234 passes through the filter unit 50 and is then discharged to the outside via the air outlet 522.

As described above, in order to clean the dust separation module 700, the main body cover 16 may be rotated, and then the dust separation module 700 may be rotated in one direction. Then, when the dust separation module 700 is pulled, the dust separation module 700 may be separated from the main body 2.
