It is an invention that discloses.

BACKGROUND ART In general, a vacuum cleaner is a home appliance that sucks up small garbage or dust and fills a dust bin in a product by a method of sucking air using electricity, and is commonly referred to as a vacuum cleaner.

Such cleaners may be classified into manual cleaners for cleaning while a user directly moves the cleaner, and automatic cleaners for performing cleaning while driving by itself. Manual cleaners may be classified into canister-type cleaners, upright cleaners, handheld cleaners, and stick-type cleaners according to the shape of the cleaner.

In household cleaners, canister-type vacuum cleaners have been widely used in the past, but recently, handheld vacuum cleaners and stick vacuum cleaners, which provide convenience in use by integrally providing a dust bin and a cleaner body, have been widely used.

The main body of the canister type vacuum cleaner is connected to the intake by a rubber hose or pipe, and in some cases, a brush can be inserted into the intake.

A handheld vacuum cleaner maximizes portability, and is light in weight, but has a short length, so a sitting area may be limited. Thus, it is used to clean localized areas, such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used standing up, so you can clean without bending your back. Therefore, it is advantageous to clean while moving a large area. If the handheld vacuum cleaner cleans a narrow space, the stick type cleaner can clean a wider space and can clean high places that are out of reach. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

However, in the stick vacuum cleaner, the capacity of the dust bin for storing the collected dust is small, and the user has to empty the dust bin every time, which is inconvenient.

The prior patent document includes a vacuum cleaner including a dust collection container in which foreign substances are collected, and a docking station connected to the dust collection container to remove foreign substances collected in the dust collection container, and the dust collection container is provided to be docked to the docking station, The docking station is configured to include a suction device for sucking foreign substances and internal air in the dust collection container docked at the docking station.

In addition, the prior patent document is configured to include a collection unit for collecting foreign substances inside the docking station.

However, the above prior patent document has a problem in that, after the suction of the suction device (suction fan) is finished, foreign substances that may stick around the dust collector during the suction process cannot be removed.

Therefore, when the user uses the vacuum cleaner again after the suctioning of the foreign matter is completed, the user has no choice but to touch the foreign matter (hereinafter, residual dust) exposed around the dust collector with his hand, and the user It is inconvenient to have to remove residual dust directly using a wet tissue or the like.

In addition, when such foreign substances are deposited inside the docking station, there is a problem that the inside of the docking station is contaminated.

Accordingly, the dust existing in the dust bin 2600 by the suction force of the dust collection motor 200 moves in the horizontal direction along the dust box body 2610 and then changes its flow direction in the vertical direction as it enters the first flow path 700, thereby changing the flow direction of the housing. It is collected in the dust storage module 300 accommodated in the lower part of the inside of the 100.

That is, dust in the dust bin 2600 of the cleaner 2 may be collected into the dust storage module 300 of the cleaner station 1 by the suction force of the dust collecting motor 200 and the action of gravity.

Through this configuration, since dust in the dust bin can be removed without a user's separate manipulation, user convenience can be provided. In addition, the user can eliminate the hassle of having to empty the dust bin every time. In addition, when the dust bin is emptied, it is possible to prevent dust from scattering.

The cleaner station 1 according to the embodiment of the present invention may further include a cover opening unit 500 .

The cover opening unit 500 is provided to open the discharge cover 2620 of the cleaner 2 . Referring to FIG. 4 , the cover opening unit 500 may include a push protrusion 511, a cover opening gear 520, and a cover opening motor (not shown).

More specifically, the push protrusion 511 may be disposed on the coupling part 110 at a position where the coupling lever 2630 can be pressed, and may linearly reciprocate to press the coupling lever 2630 . More specifically, the push protrusion 511 may protrude upward in the long axis direction of the housing at a position facing the coupling lever 2630 provided to open the discharge cover 2620 of the cleaner 2 .

The cover opening unit 500 may further include a protrusion support 512 , a protrusion neck 513 and a gear coupling block 514 .

At this time, the protrusion support 512 is coupled to the lower end of the push protrusion 511 and has a linear reciprocating motion together with the push protrusion 511, and the lower surface of the protrusion support 512 is flat of the second coupling part 112. Arranged to face the surface 112a, the protrusion support 512 can linearly reciprocate on the flat surface 112a.

The protrusion neck 513 may be coupled to the lower surface of the protrusion support 512 and disposed in the protrusion neck insertion hole 112aa. The protrusion neck 513 may be coupled between the protrusion support 512 and the gear coupling block 514 . That is, the protrusion support 512 is coupled to the upper portion of the protrusion neck 513, the gear coupling block 514 is coupled to the lower portion of the protrusion neck 513, and the push protrusion 511 is coupled to the upper portion of the flat surface 112a. ) and the protrusion support 512 are exposed, and a gear coupling block 514 may be disposed below the flat surface 112a. The protrusion neck 513 may have a narrower width than the protrusion support 512 and the gear coupling block 514 .

The gear coupling block 514 is disposed below the flat surface 112a and can linearly reciprocate by the movement of the cover opening gear 520 .

The cover opening motor may provide power for rectilinearly reciprocating the push protrusion 511 to the cover opening gear 520 . More specifically, the cover opening gear 520 is coupled to the cover opening motor, and the push protrusion 511, the protrusion support 512, the protrusion neck 513 and the gear coupling block 514 are formed by using the power of the cover opening motor. can be moved together. The cover opening gear 520 meshes with the first cover opening gear 521 receiving rotational power from the shaft of the cover opening motor and the first cover opening gear 521, and transmits linear reciprocating motion to the push protrusion 511. A second cover opening gear 522 may be included.

In this case, the first cover opening gear 521 may be formed of a pinion gear, and the second cover opening gear 522 may be formed of a rack gear.

In other words, when the main body of the cleaner 2 is fixed to the coupling part 110, the cover opening motor moves the push protrusion 511 through the cover opening gear 520 and opens the discharge cover 2620 to open the dust box body. (2610).

The cleaner station 1 according to the embodiment of the present invention may further include a door unit 600 .

Referring to FIG. 5 , the door unit 600 may include a door 610 , a door arm 620 and a door motor 630 .

The door 610 is hinged to the coupling part 110 and is opened in the direction in which the discharge cover 2620 is opened so that the outside of the housing 100 can communicate with the first flow path 700 . More specifically, the door 610 is coupled to the door hinge 605 disposed on the third coupling part 113 and is provided to rotate around the door hinge 605 .

When the door arm 620 pulls the door 610 while the door 610 blocks the dust passage hole 113a and closes the inside and outside of the housing 100, the door 610 moves the vacuum cleaner station 1 ) Can be rotated toward the inside of the housing 100. Meanwhile, when the door arm 620 pushes the door 610 , the door 610 may rotate toward the outside of the cleaner station 1 .

The door motor 630 may provide power for rotating the door 610 to the door arm 620 . Specifically, the door motor 630 may rotate the door arm 620 forward or reverse. Here, the forward direction may mean a direction in which the door arm 620 pulls the door 610 toward the inside of the housing 100 . Also, the reverse direction may mean a direction in which the door arm 620 pushes the door 610 toward the outside of the housing 100 .

The door arm 620 is provided to open and close the door 610 by being coupled to the door 610 and serves to connect the door 610 and the door motor 630. The door arm 620 may open and close the door 610 using power generated by the door motor 630 .

For example, the door arm 620 may include a first door arm 621 and a second door arm 622 . One end of the first door arm 621 may be coupled to the door motor 630 . The first door arm 621 may rotate by the power of the door motor 630 . The other end of the first door arm 621 may be rotatably coupled to the second door arm 622 .

The other end of the second door arm 622 may be coupled to the door 610 . The second door arm 622 may push or pull the door 610 .

Hereinafter, the arrangement of the second flow path 710 formed in the first flow path 700 and a specific structure for removing residual dust, which is a problem of the present invention, will be described with reference to FIGS. 4 and 6 .

The cleaner station 1 may further include a first flow path 710 .

First, referring to FIG. 6 , the first flow path 700 is accommodated inside the housing 100 and disposed vertically, and air containing dust escaped from the dust bin 2600 of the cleaner 2 flows. It may be provided to provide a space (S1) that can be. That is, when the cleaner 2 is coupled to the cleaner station 1 , the dust container 2600 may be disposed at the open upper end of the first passage 700 . At this time, since the open lower end of the first passage 700 is coupled to the dust storage module 300, when the discharge cover 2620 is separated from the dust box body 2610, the dust inside the dust box body 2610 is removed. Dust may be collected by the dust storage module 300 through one flow path 710 .

Also, the open upper end of the first flow path 700 may be defined as a dust passage hole 113a. As described above, the dust passage hole 113a may serve as a main hole for sucking dust from the dust bin 2600 into the housing 100 .

A second flow path 710 may be provided in the first flow path 700 to remove residual dust. At this time, referring to FIG. 4 , the second flow path 710 is a push protrusion 511 on the first flow path 700 in a direction in which the push protrusion 511 presses the coupling lever 2630 coupled to the dust box body 2610. ), and may be provided in a form penetrating the inside and outside of the first flow path 700. The second passage 710 may be provided in the form of a long hole in a horizontal direction, for example. More specifically, the second passage 710 may be formed by penetrating the first passage 700 at the same level as the flat surface 112a through which the protrusion support 512 rectilinearly reciprocates.

The second passage 710 may be formed lower than the dust passage hole 113a. Also, the second passage 710 may be formed to have a smaller cross-sectional area than the through-sectional area of the dust passage hole 113a.

With this configuration, when the dust collecting motor 200 generates a suction force in a state in which the dust passing hole 113a is closed, a strong suction force concentrated in a small cross-sectional area can be applied to the second flow path 710, effectively remaining dust. can be removed.

In addition, with this configuration, when the discharge cover 2620 of the dust bin 2600 is opened, the remaining dust accumulated in the vicinity of the push protrusion 511 inside the cleaner station 1 is affected by the suction force of the dust collection motor 200. It can be sucked into the first flow path 700 through the second flow path 710 by the. That is, if the main suction path is a path that is sucked into the first flow path 700 through the dust bin 2600 and the dust passage hole 113a, the remaining dust from the dust bin 2600 is removed from the vicinity of the push protrusion 511 (the first suction path). 2. A path that is sucked into the first flow path 700 via the second flow path 710 from (which may be referred to as the vicinity of the coupling part 112) may be referred to as a bypass intake path. The cleaner station 1 according to an embodiment of the present invention can remove dust that may be deposited in a space near the push protrusion inside the cleaner station through the bypass suction path, so that the inside of the cleaner station is not contaminated. It has the effect of reducing the risk and enabling hygienic management of the cleaner station.

Hereinafter, driving of the dust collecting motor 200 for removing residual dust through the bypass suction path will be described.

After the vacuum cleaner 2 is coupled to the coupling part 110 and the door unit 600 opens the door 610, the cover opening unit 500 opens the discharge cover 2620 so that the inside and outside of the dust box body 2610 When the first flow path 700 is in communication, the dust collection motor 200 may be driven for a first time period t1. At this time, the air containing dust passes through the main intake path and the bypass intake path to flow into the inner space S1 of the first flow path 700 and the dust combined with the lower end of the first flow path 700. Dust may be collected in the bag 310 .

When the dust collecting motor 200 stops driving after the first time t1 has elapsed, the door unit 600 may close the door 610 . When the door arm 620 pushes the door 610 in the direction of closing the door 610, the discharge cover 2620 may also move along with the door 610 in the direction of closing the dust container 2600. Accordingly, the discharge cover 2620 is coupled to the dust box body 2610 again, and the door 610 also closes the dust passage hole 113a.

After the door 610 is closed by the door unit 600, in a state where the dust bin 2600 is still coupled to the coupling part 110, the dust collection motor 200 is re-driven for a second time period t2 to increase the suction force. can cause Here, since the main intake path is closed, the air containing dust passes only through the bypass intake path and flows into the inner space S1 of the first flow path 700 . At this time, if the dust collecting motor 200 generates the same suction power, the suction force of the dust collecting motor 200 is greater toward the bypass suction path than when the dust collecting motor 200 was driven while the door 610 was previously opened. can be focused

The fact that the suction force of the dust collecting motor 200 is concentrated on the bypass suction path means that the suction force acting on the remaining dust increases. That is, since the dust collecting motor 200 is configured to be re-driven in a state in which the discharge cover 2620 and the door 610 are closed, there is an effect of increasing the removal efficiency of residual dust.

In addition, when dust is sucked by the dust collecting motor 200 in the state where the discharge cover 2620 and the door 610 are open, it is directed to the inside of the door 610 (the opposite side of the surface facing the discharge cover 2620). Also, dust may fly away and stick to it, but there is an advantage in that the stuck dust can also be removed by configuring the dust collection motor 200 to be re-driven while the door 610 is closed.

Meanwhile, the first time period t1 and the second time period t2 may be preset in a controller (not shown) of the cleaner station 1 . In this case, the first time t1 for inhaling more dust may be set to be equal to or longer than the second time t2 for inhaling the remaining dust. The control unit may be accommodated inside the housing 100 and may be provided to control driving, stopping, and suction power of the dust collecting motor 200 .

FIG. 7 is a view looking down at the coupling part 110 from above, and FIG. 8 is a cross-sectional view of a state in which the cleaner 2 is coupled to the coupling part 110 .

Referring to FIGS. 7 and 8 , when a direction in which the protrusion support 512 rectilinearly reciprocates is referred to as a first direction and a direction perpendicular to the first direction is referred to as a second direction, The size D1 in the second direction may be smaller than the size D2 of the flat surface 112a in the second direction. In other words, the vertical wall 112b of the second coupling part 112 may be spaced apart from each end of the protrusion support 512 in the second direction by a predetermined distance.

Foreign substances that have flowed into the second coupling part 112 of the cleaner station 1 show a random accumulation pattern, and most of them can be removed by the configuration of the second passage 710 formed in the first passage 700 . However, when the size D1 of the protrusion support 512 in the second direction and the size D2 of the flat surface 112a of the second coupling part 112 in the second direction are almost the same, that is, the protrusion support 512 Possibility that deposited foreign matter may not escape into the second flow path 710 when each end disposed in the second direction is in contact with or disposed too close to the vertical wall 112b of the second coupling portion 112 this gets bigger

At this time, in particular, when hard and small foreign substances such as grains of sand are deposited in the small gap between the end of the protrusion support 512 and the vertical wall 112b, resistance to linear reciprocating motion may occur, and the protrusion support 512 may cause foreign matter. It can make a creaking noise as it rubs against the grass. To solve this problem, the cleaner station 1 according to an embodiment of the present invention may be configured such that a predetermined distance is separated between the end of the protrusion support 512 and the vertical wall 112b. Here, when the discharge cover 2620 is opened, the distance from which the discharge cover 2620 is opened falls due to gravity and flows into the second coupling portion 112 through the gap between the dust box body 2610 and the coupling portion 110. It can be selected considering the size of possible foreign matter (see Fig. 8).

Through this configuration, it is possible to solve the above-described problems (accumulation of foreign matter, generation of resistance to linear reciprocating motion, generation of noise, etc.).

Meanwhile, referring to FIG. 7 again, the moving axis L1 of the moving direction of the protruding support 512 performing linear reciprocating motion may be disposed at the center of the flat surface 112a in the second direction. In other words, a distance from the left end of the protrusion support 512 to the near vertical wall 112b may be equal to a distance from the right end of the protrusion support 512 to the near vertical wall 112b. That is, the second coupling part 112 and the protrusion support 512 may have a symmetrical structure around the moving axis L1 of the protrusion support 512 . Through this configuration, it is possible to equally set the left and right separation distances between the protrusion support 512 and the vertical wall 112b as the minimum distance around the moving axis L1 of the protrusion support 512, and efficiently clean the station. (1) has the advantage of being able to design the interior space.

Hereinafter, the structure of the coupling lever 2630 of the cleaner 2 will be described in detail.

9 is a perspective view of the coupling lever 2630 of the cleaner 2, FIG. 10 is a perspective view of the coupling lever 2630 of FIG. 9 viewed from another direction, and FIG. 11 is a side view of the coupling lever 2630 of FIG. 12 is a perspective view illustrating a relationship between the direction in which the lever inclined portion 2632 of the coupling lever 2630 is formed and the moving direction A of the push protrusion 511.

9 to 12, the coupling lever 2630 may include a lever body 2631, a lever inclined portion 2632, a lever sidewall 2633, a lever pressing portion 2634, and a hook pressing portion 2635. can

The lever body 2631 may constitute a part of the exterior of the coupling lever 2630. The lever body 2631 may extend along the longitudinal direction of the dust container body 2610 . At this time, the lever body 2631 may be bent to a predetermined length from both ends in a direction perpendicular to the direction in which it extends toward the center of the dust box body 2610 to form an inner space inside the coupling lever 2630. In addition, a lever inclination portion 2632 may be connected to one end in a direction in which the lever body 2631 extends.

The lever inclined portion 2632 is connected to the lever body 2631 at one end where the lever body 2631 extends and may be formed to extend from the lever body 2631 .

At this time, the lever inclined portion 2632 may be provided with a dust discharge groove 2632a in which the lever inclined portion 2632 is recessed. Since the dust discharge groove 2632a is provided in the coupling lever 2630, the remaining dust flowing into the coupling lever 2630 can pass through the dust discharge groove 2632a by the suction operation of the dust collection motor 200 and is removed. It can be introduced into 1 flow path 700 and removed.

The lever inclined portion 2632 may be inclined toward the center of the dust container body 2610 based on a state in which the coupling lever 2630 is coupled to the dust container body 2610. In other words, the lever inclined portion 2632 extends from the lever body 2631 and may be formed by tilting a predetermined angle θ upward with respect to the moving direction A of the coupling lever 2630 . The lever inclined portion 2632 may be disposed obliquely with respect to the door 610 when the cleaner 2 is coupled to the coupling portion 110 . In other words, the lever inclined portion 2632 may be disposed toward the second flow path 710 when the cleaner 2 is coupled to the coupling portion 110 . With this configuration, the dust discharge groove 2632a through which residual dust should escape is not blocked by the door 610, and the remaining dust can be smoothly removed through the dust discharge groove 2632a to the second flow path 710. Yes. (See FIGS. 11 and 12)

The lever sidewall 2633 is coupled to the lever body 2631 and the lever pressing portion 2632. One or more side wall support ribs 2637 disposed toward the inside of the coupling lever 2630 may be coupled to each of the lever side walls 2633 .

The lever pressing unit 2634 may be coupled to the other end of the lever body 2631. In this case, the other end of the lever body 2631 may refer to a direction opposite to the direction in which the lever inclined portion 2632 is disposed. The lever pressing portion 2634 may be formed to extend from the other end of the lever body 2631 in a direction perpendicular to the direction in which the lever body 2631 is extended. The lever pressing part 2634 is a component to which an external force is applied by a user, and when an external force is applied to the lever pressing part 2634, the coupling lever 2630 moves in the longitudinal direction of the dust bin 2600 to close the discharge cover 2620. will open up

A lever hole 2634a formed to pass through the lever pressing portion 2634 may be provided in the lever pressing portion 2634 . The lever hole 2634a may be provided in the form of a long hole penetrating in a direction in which the lever sidewall 2633 is disposed. Also, the lever hole 2634a and the dust discharge groove 2632a may be disposed to face each other.

When the dust collection motor 200 generates a suction force by the lever hole 2634a and the dust discharge groove 2632a disposed to face each other, the dust discharge groove ( 2632a), an airflow communicating to the second flow path 710 can be formed, and the airflow is not blocked by the lever pressing part 2634 during the suction operation of the dust collection motor 200, so the suction effect of remaining dust can be further improved. You will be able to.

The hook pressing part 2635 may be coupled to the lever pressing part 2634. One side of the lever pressing portion 2634 may be coupled to the lever body 2631 and the other side of the lever pressing portion 2634 may be coupled to the hook pressing portion 2635 . At this time, the hook pressing portion 2635 may be formed to extend in the same direction as the lever body 2631 . The hook pressing unit 2635 may cause elastic deformation of the coupling hook 2660 by pressing the coupling hook 2660 of the discharge cover 2620 . In other words, when an external force is applied to the lever pressing portion 2634 by the user, the hook pressing portion 2635 presses the coupling hook 2660 and the discharge cover 2620 may be opened (see FIG. 12).

FIG. 13 is a schematic diagram of a suction path of remaining dust through the dust discharge groove 2632a of the coupling lever 2630 and the second flow path 710. Referring to FIG.

Referring to FIGS. 12 and 13 , residual dust that flows into the second coupling part 112 in the process of opening the discharge cover 2620 or in the process of dust being sucked into the cleaner station 1 is removed from the second coupling part ( 112 may be sucked into the first flow path 700 through the second flow path 710 . In addition, in the process of opening the discharge cover 2620 or in the process of sucking dust into the vacuum cleaner station 1, the flow into the inside of the coupling lever 2630 (the space between the coupling lever 2630 and the dust box body 2610) Residual dust may be sucked into the first flow path 700 through the second flow path 710 from the dust discharge groove 2632a.

Next, a method for removing residual dust using the cleaner system 1000 according to an embodiment of the present invention will be described with reference to FIG. 14 .

14 is a flowchart of a method for removing residual dust using the cleaner system 1000 according to an embodiment of the present invention.

First, when it is confirmed whether the cleaner 2 is coupled to the coupling part 110 (S100), in the door opening step, the door 610 provided in the cleaner station 1 is opened so that the outside and inside of the cleaner station 1 communicate with each other. (S200) At this time, the door 610 may be opened by the door unit 600 of the cleaner station 1 described above.

Meanwhile, a coupling sensor (not shown) may be disposed at the coupling portion 110 to determine whether the cleaner 2 is coupled to the coupling portion 110 . The combined sensor may be a contact sensor such as a micro switch or a non-contact sensor such as an infrared sensor.

Next, in the step of opening the discharge cover 2620, the discharge cover 2620 for opening and closing the dust bin 2600 is opened (S300). At this time, the opening of the discharge cover 2620 is the cover of the cleaner station 1 described above. It may be performed by the opening unit 500.

When both the door 610 and the discharge cover 2620 are opened and the inside of the dust box body 2610 communicates with the first flow path 700, the dust collection step is performed and the dust collection motor 200 is driven to clean the vacuum cleaner station 1. Dust is sucked into the inside. (S400) The dust collecting motor 200 may be driven for a first predetermined time period t1. At this time, air containing dust passes through the main intake path and the bypass intake path to flow into the first flow path 700 , and dust may be collected in the dust bag 310 .

When the dust collecting motor 200 stops driving and stops after the first time t1 has elapsed (S500), the door unit 600 may close the door 610 together with the discharge cover 2620 in the door closing step. (S600) When the door arm 620 of the door unit 600 pushes the door 610 in the direction of closing the door 610, the discharge cover 2620 also moves in the direction of closing the dust bin 2600, The discharge cover 2620 is coupled to the dust box body 2610 again, and the door 610 also closes the dust passage hole 113a.

Meanwhile, after the door closing step, a residual dust removing step of removing remaining dust existing around the dust bin 2600 is performed (S700).

At this time, in the step of removing remaining dust, the dust collection motor 200 is re-driven for a predetermined time while the cleaner 2 is coupled to the cleaner station 1, and the remaining dust is returned to the inside of the cleaner station 1. It is a process of inhalation. More specifically, after the door 610 is closed by the door unit 600, in a state where the dust bin 2600 is coupled to the coupling part 110, the dust collecting motor 200 is re-driven for a second time period t2. This can generate suction power. At this time, since the main intake path is closed, the air containing dust passes only through the bypass intake path and flows into the first flow path 700 while the dust collecting motor 200 is re-driving. Accordingly, when the dust collecting motor 200 generates the same suction force, the suction force may be more concentrated in the bypass suction path. That is, since the dust collection motor 200 is configured to be re-driven in a state in which the discharge cover 2620 and the door 610 are closed, the suction force provided to the remaining dust increases, thereby increasing the removal efficiency of the remaining dust.

On the other hand, the bypass suction path may be a path through which residual dust flowing into the second coupling part 112 is sucked into the first channel 700 through the second channel 710, or the coupling lever 2630 Residual dust flowing inward may be a path through which dust discharge grooves 2632a and the second passage 710 are sucked into the first passage 700 .

In addition, the first time period t1 and the second time period t2 may be predetermined times preset in a controller (not shown) of the cleaner station 1, and the first time period during which more dust should be sucked ( t1) may be set to be longer than or equal to the second time period t2 for inhaling the remaining dust. The control unit may be accommodated inside the housing 100 and may control driving, stopping, and suction power of the dust collecting motor 200 .

Finally, when the second time period t2 elapses, the dust collecting motor 200 is stopped (S800) and all operations of the cleaner station 1 are terminated.

As described above, according to the present invention, residual dust accumulated near the push protrusion inside the cleaner station can be effectively sucked through the second passage provided to pass through the outside and inside of the first passage.

In addition, according to the present invention, residual dust accumulated inside the coupling lever outside the dust bin of the cleaner can be effectively removed through the dust discharge groove formed in the coupling lever of the cleaner.

In addition, according to the present invention, through a residual dust removal step of re-driving the dust collection motor for a predetermined time after suction of the dust inside the dust bin is finished and the discharge cover is closed, the suction force for sucking the remaining dust is applied to the second passage and the second flow path. Since it can be concentrated into the dust discharge groove, residual dust can be removed more effectively.

Although specific embodiments of the present invention have been described and shown above, the present invention is not limited to the described embodiments, and those skilled in the art can variously change to other specific embodiments without departing from the spirit and scope of the present invention. It will be appreciated that modifications and variations are possible. Therefore, the scope of the present invention should not be determined by the described embodiments, but should be determined by the technical ideas described in the claims.
