Abstract

The present invention relates to a cleaner system and a control method thereof. The cleaner system comprises: a dust passage hole which is formed in a coupling part, and includes an exit end and an entry end, wherein the exit end is connected to a flow path part, and when a cleaner is attached, the entry end communicates with a discharge port of a dust container of the cleaner; and a door which is hinge-coupled to the coupling part and opens and closes the dust container formed in the coupling part. The door stops for at least a specific duration when the rotation angle from the discharge port reaches a first opening angle, and stops for at least a specific duration when the rotation angle reaches a second opening angle smaller than the first opening angle. In a dust collecting step, dust inside the dust container can be emptied without significant air resistance when the door rotates to the first opening angle. In an additional dust collecting step, air flow in the dust passage hole changes rapidly when the door rotates to the second opening angle, and thus dust adsorbed on a discharge cover can be effectively removed.

Description

Cleaner system and its control method {CLEANER SYSTEM AND CONTROLLING METHOD THEREOF}

The present invention relates to a cleaner system and a control method thereof, and more particularly, to a cleaner system including a vacuum cleaner that sucks in dust from the outside and a cleaner station that sucks dust stored in the cleaner into the cleaner station, and a control method thereof. .

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

The Hand Vacuum Cleaner maximizes portability and is light in weight, but has a short length, so the cleaning area may be limited while sitting. 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.

In addition, recently, a robot cleaner that self-cleans without a user's manipulation has been used. The robot cleaner automatically cleans the area to be cleaned by sucking foreign substances such as dust from the floor while traveling on its own in the area to be cleaned.

However, conventional handheld vacuum cleaners, stick vacuum cleaners, and robot cleaners have a small capacity of dust bins for storing collected dust, so that users have to empty the dust bins every time.

In addition, when the dust bin is emptied, dust is scattered, which has a harmful effect on the user's health.

In addition, when remaining dust in the dust bin is not removed, there is a problem in that the suction power of the vacuum cleaner is reduced.

In addition, if the remaining dust in the dust bin is not removed, there is a problem in that a bad smell is generated due to the residue.

As Prior Patent Document 1, Korean Patent Publication No. 10-2020-0074001 discloses a cleaning device including a vacuum cleaner and a docking station.

Prior Patent Document 1 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, Prior Patent Document 1 is configured to include a collection unit for collecting foreign substances inside the docking station. According to the prior patent literature, when the suction device disposed in the docking station is operated, the dust collection container of the vacuum cleaner is cleaned by sucking in foreign substances collected in the dust collection container by negative pressure and collecting the dust in the collecting unit.

As one of the embodiments of Prior Patent Document 1, the docking station includes a flow rate changing device. The flow rate change device includes a flow path cover capable of opening and closing a connection flow path and an opening/closing unit driving the flow path cover. The opening/closing unit is formed by alternating a plurality of pressing protrusions and non-pressurizing parts, and as the opening/closing unit rotates, the pressing protrusion repeatedly presses the flow path cover so that the flow path cover repeatedly opens and closes the connection passage.

However, in Prior Patent Document 1, when referring to the drawing, even if the flow path cover is structurally opened to the maximum, it will be opened less than about 20 degrees, so the dust adsorbed on the upper surface of the flow path cover can be effectively separated even in the operation of the opening and closing unit. There was a problem that there was no, and there was also a problem that the opening angle of the flow path cover was small and interfered with the air flow. In addition, Prior Patent Document 1 also had a problem of having to have a separate drive motor to drive the opening and closing unit.

As Prior Patent Document 2, Korean Patent Registration No. 10-2208334 is proposed. Prior Patent Document 2 discloses a cleaning device including a vacuum cleaner and a docking station and a control method thereof.

Prior Patent Document 2 proposes a cleaning device including a docking station that automatically and effectively discharges foreign substances from a dust collection box of a vacuum cleaner by providing an irregular suction device.

For the above-described problem, Prior Patent Document 2 includes a suction device for moving air from a dust container into a docking station and a flow control device for opening or closing the suction passage. The control unit operates the suction device or controls the flow control device to periodically open and close the suction flow path while the suction device is operating. According to Prior Patent Document 2, irregular air flow occurs inside the flow path as the flow path is opened and closed by the flow control device, and the irregular air flow presents an effect of discharging dust more efficiently.

However, by combining the flow control device of Prior Patent Document 2 with Prior Patent Document 1, the flow rate change device and the flow control device may be simultaneously provided on one connection passage. However, the flow control device and the flow change device each have a driving motor and operate independently, and cannot be an effective method for separating dust adsorbed on the flow path cover.

Prior Patent Document 3 proposes US Patent Publication No. 2021-0030244. Prior Document 3 proposes a cleaning system for removing dust from a robot cleaner.

Prior Patent Document 3 has a station, a handheld cleaner is coupled to one side of the station, and a robot cleaner is coupled to the other side of the station. The dust bin of the robot cleaner and the dust bin of the handheld cleaner communicate with each other, and when the suction motor of the robot cleaner operates, dust collected in the dust bin of the robot cleaner moves to the handheld cleaner and empty the dust bin of the robot cleaner.

However, by combining Prior Patent Literature 3 with Prior Patent Literature 1, the air flow inside the connection passage may be irregularly changed by the suction motor of the vacuum cleaner. However, even in this case, since the flow rate change device operates independently with a separate drive motor, it cannot be an effective method for separating dust adsorbed on the flow path cover.

Prior Patent Document 1: Korean Patent Publication No. 10-2020-0074001 Prior Patent Document 2: Korean Patent Registration No. 10-2208334 Prior Patent Document 3: US Patent Publication No. 2021-0030244

The discharge cover 222 may be coupled to the dust container 220 through hook coupling. Meanwhile, the discharge cover 222 may be separated from the dust bin 220 through the coupling lever 222c. The coupling lever 222c may be disposed in front of the dust bin. Specifically, the coupling lever 222c may be disposed on an outer surface of the front side of the dust bin 220 . When an external force is applied, the coupling lever 222c may elastically deform the hook extending from the cover body 222a to release the hook coupling between the cover body 222a and the dust container body 221 .

Since the vibration spring support 222e has elasticity, at least a portion thereof may be sunk into the dust bin when in contact with the vibration spring 141d. At this time, since the vibration spring 141d or the vibration spring cover 141e is inserted into the hollow of the discharge cover body 222a, the elastic cover 222 and the door 141 are aligned in place.

Accordingly, when the door arm 143 rotates in the reverse direction, the dust passage hole 121a may be at least partially closed. The forward direction may be the reverse direction and the opposite direction.

With this configuration, when the user grabs the handle 216, the relatively heavy suction motor 214 is located at the lower side of the gravity direction, and the user can move the cleaner 200 in a direction parallel to the ground. Convenience of coupling or separating the cleaner station 200 from the cleaner station 100 may be provided.

In addition, when the cleaner 200 is coupled to the cleaner station 100, the battery 240 may be disposed farther from the ground than the suction motor axis a1. With this configuration, the cleaner 200 can be stably supported by the cleaner station 100 .

When the cleaner 200 is coupled to the cleaner station 100, the suction passage through line a2 may be formed parallel to the axis line C of the dust collection motor. With this configuration, there is an effect of minimizing a space occupied on a horizontal surface when the cleaner 200 is coupled to the cleaner station 100 .

At this time, the coupling part 120 may be disposed between the suction passage through-line (a2) and the dust collecting motor axis (C). A fixing member 131 may be disposed between the suction flow passage line a2 and the dust collection motor shaft line C. A cover opening unit 150 may be disposed between the suction flow passage line a2 and the dust collecting motor axis C. With this configuration, the user can connect or separate the cleaner 200 from the cleaner station 100 with a simple motion of moving the cleaner 200 parallel to the ground, and the dust bin 220 can be fixed. , Convenience of opening the dust bin 220 may be provided.

The gripper penetration line a3 may intersect the dust collecting motor axis C at a predetermined angle. At this time, the intersection point P6 of the through line a3 of the gripper and the axis line C of the dust collecting motor may be located inside the housing 110 . With this configuration, there is an advantage in that the user can couple the cleaner 200 to the cleaner station 100 by simply pushing his/her arm toward the side of the cleaner station 100 while holding the cleaner 200. . In addition, since the relatively heavy dust collection motor 191 is accommodated in the housing 110, even if the user pushes the cleaner 200 into the cleaner station 100 hard, the cleaner station 100 is prevented from shaking. has the effect of

When the cleaner 200 is coupled to the cleaner station 100, the cyclone line a4 may intersect the longitudinal axis of the cleaner station 100. That is, the flow axis of the dust separator 213 may cross the longitudinal axis of the cleaner station 100 . At this time, the intersection of the flow axis of the dust separator 213 and the longitudinal axis of the cleaner station 100 may be located inside the housing 110, and more specifically, inside the flow path part 180.

When the cleaner 200 is coupled to the cleaner station 100, the cyclone line a4 may intersect the dust collecting motor axis line C. At this time, the intersection of the cyclone line (a4) and the dust collecting motor axis (C) may be located inside the housing 110, more specifically, inside the flow path part 180. With this configuration, the cleaner 200 can be stably supported by the cleaner station 100 in a state in which the cleaner 200 and the cleaner station 100 are coupled, and an effect of reducing flow path loss when the dust bin 220 is emptied. there is

When the cleaner 200 is coupled to the cleaner station 100, the dust bin through line a5 may cross the longitudinal axis of the cleaner station 100. That is, the longitudinal axis of the dust bin 220 may cross the longitudinal axis of the cleaner station 100 . At this time, the intersection of the longitudinal axis of the dust bin 220 and the longitudinal axis of the cleaner station 100 may be located inside the housing 110, and more specifically, inside the flow path part 180.

Meanwhile, when the cleaner 200 is coupled to the cleaner station 100, the handle 216 may be disposed at a greater distance from the ground than the dust bin penetration line a5. With this configuration, when the user grabs the handle 216, the user can connect or separate the cleaner 200 from the cleaner station 100 by simply moving the cleaner 200 in a direction parallel to the ground. convenience can be provided.

Also, when the cleaner 200 is coupled to the cleaner station 100, the battery 240 may be disposed at a greater distance from the ground than the dust bin penetration line a5. With this configuration, since the battery 240 presses the body 210 of the cleaner 200 with its own weight, the cleaner 200 can be stably supported by the cleaner station 100 .

12 is a flow chart for explaining the operation steps of the cleaner system 10 according to the present invention, and FIG. 12 shows the operation of each motor over time in the control method of the cleaner system 10 according to the present invention. A drawing for explanation is disclosed.

A control method of the cleaner system 10 according to the present invention will be described with reference to FIGS. 11 and 12 .

The control method of the vacuum cleaner system of the present invention includes a combination check step (S10), a dust box fixing step (S20), a cover opening step (S30), a door opening step (S40), a dust collection step (S50), an additional dust collection step (S60), A door closing confirmation step (S70) and a fixing release step (S80) are included.

In the coupling confirmation step ( S10 ), it may be checked whether the cleaner 200 is coupled to the coupling part 120 of the cleaner station 100 .

Specifically, in the coupling confirmation step (S10), when the cleaner 200 is coupled to the coupling portion 120, the coupling sensor 125 disposed on the guide protrusion 123 may come into contact with the battery housing 230, and coupling The sensor 125 may transmit a signal indicating that the cleaner 200 is coupled to the coupler 120 . Alternatively, according to the embodiment, the combination sensor 125 of the non-contact sensor type disposed on the side wall 124 may detect the presence of the dust bin 220, and the combination sensor 125 may be connected to the coupling part 120 by the cleaner 200. It can transmit a signal that it is coupled to.

Accordingly, in the coupling confirmation step ( S10 ), the control unit 400 may determine that the cleaner 200 is coupled to the coupling unit 120 by receiving the signal generated by the coupling sensor 125 .

Meanwhile, in the coupling confirmation step (S10) of the present invention, the controller 400 determines whether the cleaner 200 is properly coupled through whether or not the charging unit 128 supplies power to the battery 240 of the cleaner 200. can check whether Therefore, in the coupling confirmation step (S10), the controller 400 receives a signal from the coupling sensor 125 that the cleaner 200 is coupled, and checks whether power is supplied to the battery 240 through the charging unit 128. Thus, it is possible to check whether the cleaner 200 is coupled to the coupling part 120 of the cleaner station 100.

Specifically, the controllers 400 and 401 pulse the cleaner 200 through the corresponding terminal when the cleaner 200 is coupled to the coupling unit 120 and the corresponding terminal of the cleaner is electrically connected to the charging terminal of the cleaner station 100. transmit a signal At this time, the pulse signal may be a signal generated by turning on/off the application of the charging voltage for charging the cleaner 200 by a preset number of times in a preset cycle. The control unit transmitting the pulse signal may be the control unit 401 disposed in the cleaner station.

When the control unit 402 of the cleaner receives the pulse signal, the suction motor 214 may be driven after a preset waiting time has elapsed.

The controllers 400 and 401 may adjust the open angle of the door 141 to a preset angle after the dust collecting motor 191 is driven and before the suction motor 214 is driven. The preset angle may be smaller than the angle at which the door 141 is opened while the dust collecting motor 191 is driven. For example, the preset angle may be an angle β up to the flow rate change position Pc.

In the dust container fixing step ( S20 ), when the cleaner 200 is coupled to the cleaner station 100 , the fixing member 131 may catch and fix the dust container 220 .

Specifically, when receiving a signal indicating that the cleaner 200 is coupled from the coupling sensor 125, the control unit 400 operates the fixing motor 133 forward so that the fixing member 131 fixes the dust bin 220. can make it At this time, when the fixing member 131 or the fixing part link 135 moves to the dust bin fixing position FP1, the fixation detecting unit 137 may transmit a signal indicating that the cleaner 200 is fixed. Accordingly, the control unit 400 may receive a signal indicating that the cleaner 200 is fixed from the fixation detecting unit 137 and determine that the cleaner 200 is fixed. When determining that the cleaner 200 is fixed, the control unit 400 may stop the operation of the motor 133 of the fixing unit.

Unlike this, the control unit 400 may stop the operation of the fixed motor 133 after operating the fixed motor 133 in the forward direction for a preset fixed time tf. For example, the control unit 400 may stop the operation of the fixed motor 133 after operating the fixed motor 133 in the forward direction for a period of 4 seconds or more and 5 seconds or less.

In the cover opening step ( S30 ), when the dust bin 220 is fixed to the cleaner station 100 , the controller 400 may open the discharge cover 222 of the cleaner 200 .

When receiving a signal indicating that the dust bin 220 is fixed from the fixation detection unit 137, the control unit 400 may open the discharge cover 222 by operating the cover opening motor 152 in a forward direction (S31).

Specifically, the controller 400 may drive the cover opening motor 152 in a forward direction. As a result, the push protrusion 151 can move out of its initial position to a position where it presses the coupling lever 222c. Therefore, the coupling of the hook between the discharge cover 222 and the dust box body 221 is released by the movement of the coupling lever 222c, and the discharge cover 222 is removed from the dust box body 221 by the restoring force of the torsion spring 222d. It can be separated while rotating in the direction away from it.

Meanwhile, before the push protrusion 151 presses the coupling lever 222c, the cover opening detecting unit 155f may transmit a signal indicating that the push protrusion 151 is at an initial position.

When the cover opening motor 152 is driven and the push protrusion 151 starts to move to press the coupling lever 222c, the cover opening detector 155f receives a signal indicating that the push protrusion 151 is out of its initial position. can be sent Then, the control unit 400 may receive this signal and determine that the cover opening unit 150 is normally operated.

At this time, the controller 400 may measure the time after driving the cover opening motor 152 in the forward direction through a timer (not shown) or measure the time after the push protrusion 151 moves out of the initial position. .

At this time, the controller 400 has the push protrusion 151 start from the initial position based on the rotational speed of the cover opening motor 152 and the moving distance of the push protrusion 151 until the coupling lever 222c is pressed. The time to be can be set in advance and stored. Accordingly, the control unit 400 may drive the cover opening motor 152 in the forward direction for a cover opening time tc1 equal to or longer than the time required until the coupling lever 222c is pressed. For example, the controller 400 may drive the cover opening motor 152 forward for a period of 4 seconds or more and 5 seconds or less.

After the cover opening time tc1 has elapsed, the controller 400 can change the rotation direction of the cover opening motor 152 for a preset rotation direction change time tc2 (S32).

In addition, the control unit 400 may drive the cover opening motor 152 in the reverse direction after the rotation direction change time tc2 has elapsed. As a result, the push protrusion 151 may return to the initial position (S33).

The controller 400 may drive the cover opening motor 152 until the cover opening detection unit 155f detects that the push protrusion 151 has returned to its initial position. In this case, the protrusion return time tc3 required until the push protrusion 151 returns to the initial position after pressing the coupling lever 222c may be previously set and stored in the control unit 400 . Accordingly, the controller 400 may drive the cover opening motor 152 in the reverse direction during the projection return time tc3. For example, the controller 400 may drive the cover opening motor 152 in a reverse direction for a period of 4 seconds or more and 5 seconds or less.

Meanwhile, the control unit 400 may terminate driving of the cover opening motor 152 when receiving a signal indicating that the push protrusion 151 has returned to the initial position from the cover opening detection unit 155f.

In the door opening step ( S40 ), the controller 400 may open the door 141 when the dust container 220 is fixed to the cleaner station 100 . Meanwhile, the door opening step (S40) may be performed simultaneously with the cover opening step (S30).

In detail, when receiving a signal from the fixation detecting unit 137 that the dust bin 220 is fixed, the control unit 400 operates the door motor 142 in a forward direction so that the door 141 rotates and opens the dust passage hole 121a. can be opened. That is, in the door opening step (S30), the control unit 400 may rotate the door 141 to open the dust passage hole 121a.

Meanwhile, in the present embodiment, the control unit 400 may operate the door motor 142 in the forward direction after a preset time has elapsed after receiving a signal that the dust bin 220 is fixed from the fixation detection unit 137. there is. For example, the controller 400 may operate the door motor 142 after 0.5 seconds or more and 1.5 seconds or less have elapsed after the dust container 220 is fixed.

With this configuration, after waiting for the time required for the push protrusion 151 to start pressing the coupling lever 222c in the cover opening step (S30), the door 141 can be opened, and the discharge cover 222 ) and the door 141 may be opened at a similar time. Therefore, when the door 141 rotates first and the dust passage hole 121a is opened, the discharge cover 222 is suddenly opened by the restoring force of the torsion spring 222d, and the door 141 and the discharge cover 222 are strongly moved. It is possible to prevent the discharge cover 222 from being separated from the dust box body 221 because the door 141 is not opened even though a collision occurs or the hook coupling between the discharge cover 222 and the dust box body 221 is released. .

Meanwhile, the controller 400 may open the dust passage hole 121a by rotating the door 141 in stages. Specifically, the control unit 400 may rotate the door 141 by a preset θ1 degree (S41), and then stop the rotation of the door 141 for a preset time (S42). For example, after rotating the door 141 by 25 degrees or more and 35 degrees or less, the control unit 400 may stop the rotation of the door 141 for a period of 4 seconds or more and 5 seconds or less.

At this time, the rotation angle of the door 141 is based on the position when the door 141 blocks the dust passage hole 121a, and the door 141 is hinged to the housing 110. It may mean a rotation angle.

After the rotation of the door 141 stops for a preset time, the controller 400 may further rotate the door 141 by a preset θ2 degree. For example, the controller 400 may further rotate the door 141 by 45 degrees or more and 55 degrees or less (S43).

As a result, when the cover opening step (S30) and the door opening step (S40) proceed, the discharge cover 222 of the dust bin 220 rotates to open the inner space of the dust box body 221, and the door 141 opens. While rotating, the dust passage hole 121a is opened so that the inner space of the dust bin 220 and the flow path 180 of the cleaner station 100 may be in communication with each other.

Meanwhile, when the door arm 143 moves to a preset door open position Po, the door open/close detection unit 144 may detect this and transmit a corresponding signal. Accordingly, the controller 400 may determine that the door 141 is opened and may stop the operation of the door motor 142 .

Alternatively, according to the embodiment, the control unit 400 may detect that the door 141 has sufficiently rotated through the current value applied to the door motor 142, and determine that the door 141 is opened based on this. and stop the operation of the door motor 142.

In the dust collection step (S50), when the discharge cover 222 is opened and the door 141 is rotated to open the dust passage hole 121a, the dust collection motor 191 is operated to collect dust inside the dust bin 220. can make it

The controller 400 may operate the dust collection motor 191 when a preset waiting time tw for dust collection elapses after the dust container 220 is fixed.

For example, the controller 400 may start the dust collection motor 191 when a time of 6 seconds or more and 7 seconds or less has elapsed after the dust bin is fixed. At this time, the control unit 400 may gradually increase the rotational speed of the dust collecting motor 191 up to a preset third dust collection speed Ws3 for a preset suction increase time tsi. For example, the control unit 400 may gradually increase the rotational speed of the dust collecting motor 191 up to the third dust collecting speed Ws3 for a period of 3 seconds or more and 5 seconds or less. This has the advantage of increasing the lifespan of the dust collecting motor 191 by protecting the dust collecting motor 191 (S51).

As another example, the controller 400 may start the dust collection motor 191 when a time of 10 seconds or more and 11 seconds or less has elapsed after the dust bin is fixed. At this time, the control unit 400 may increase the suction power by increasing the rotational speed of the dust collecting motor 191 up to the preset third dust collecting speed Ws3. This has the advantage of minimizing the operation time of the dust collecting motor 191 to increase energy efficiency and minimize noise generation.

In the dust collection step (S50), the controller 400 may operate the dust collection motor 191 to rotate at the third dust collection speed Ws3 for a preset dust collection time ts1. For example, in the dust collecting step (S50), the control unit 400 may operate the dust collecting motor 191 to rotate at the third dust collecting speed (Ws3) for a period of 14 seconds or more and 16 seconds or less, but is not limited thereto. , The dust collection time ts1 may be changed and set according to the output of the dust collection motor 191 and the amount of dust stored inside the dust bin 220 (S52).

According to the dust collecting step (S50), the dust inside the dust bin 220 may pass through the dust passing hole 121a and the cleaner flow path 181 and be collected in the dust collecting part 170. Therefore, since the user can remove the dust in the dust bin 220 without a separate manipulation, user convenience can be provided.

Immediately after the dust collecting step (S50), the control unit 400 may set a suction reduction time to gradually decrease the rotational speed of the dust collecting motor 191 from the third dust collecting speed Ws3.

In the dust collection step (S50), the control unit 400 may stop the dust collection motor 191 when the dust collection time (ts1) elapses (S53).

At this time, the control unit 400 may gradually decrease the rotational speed of the dust collecting motor 191 from the third dust collecting speed Ws3 for a preset suction reduction time (not shown). For example, the control unit 400 may gradually decrease the rotational speed of the dust collecting motor 191 from the third dust collecting speed Ws3 for a period of 1 second or more and 3 seconds or less. This has the advantage of increasing the lifetime of the dust collecting motor 191 by protecting the dust collecting motor 191 .

Alternatively, the control unit 400 may immediately cut off the power applied to the dust collecting motor 191 . This has the advantage of minimizing the operation time of the dust collecting motor 191 to increase energy efficiency and minimize noise generation.

The additional dust collection step ( S60 ) is performed after the dust collection step ( S50 ) and is a step of removing dust adsorbed on the discharge cover 222 .

In the additional dust collection step (S60), the rotation angle of the door 141 is varied. The rotation angle is defined as an angle formed between the outlet of the dust bin 220 and the door 141 when viewed from one side. Specifically, the rotation angle of the door 141 varies between a first opening angle α and a second opening angle β smaller than the first opening angle α.

Specifically, when the rotation angle of the door reaches the first opening angle, the door is stopped for a specific time or longer. Similarly, when the rotation angle of the door reaches the second opening angle, the door is stopped for a specific time or longer. Accordingly, there is an effect that the flow of air can be changed more reliably than when the door vibrates continuously without being stopped.

Referring to FIGS. 15 and 16 , the door 141 may be fully opened in the dust collecting step (S50), and only a part of the door 141 may be opened in the additional dust collecting step (S60) (S61). 15B and 16B, the door fully opening step (S61) is formed in the coupling part before the dust collection step (S50) and disposed between the dust container 220 and the flow path part 180. Fully open. Referring to FIGS. 15A and 16A , in the partial door opening step ( S61 ), in the additional dust collection step ( S60 ) after the dust collection step ( S50 ), the dust passage hole 121a is partially opened.

In the fully open step (S61), the door 141 rotates to the open position (Po). In the fully open step ( S61 ), the rotation angle of the door 141 may be the first open angle α. Referring to FIG. 16B , in the fully open step ( S61 ), air rotates along the discharge cover 222 and more dust may be moved to the outside of the dust bin 220 .

In the partial opening step (S62), the door 141 rotates to the flow rate change position (Pc). In the partial opening step ( S62 ), the rotation angle of the door 141 may be the second opening angle β. Referring to FIG. 16A , in the partial opening step (S62), air collides with the discharge cover 222 and then is bent to move downward, so air particles may impact dust adsorbed on the discharge cover 222. . Accordingly, dust adsorbed on the discharge cover 222 may be separated from the discharge cover 222 .

Referring to FIGS. 15A and 15B or 16A and 16B , air collides with the discharge cover 222 as the door 141 alternates between a first opening angle α and a second opening angle β. may or may not collide. Accordingly, a complex turbulent flow may be formed around the discharge port, and dust adsorbed on the discharge cover 222 may be easily separated due to the turbulent flow.

Alternatively, referring to FIGS. 15C and 16C , the door 141 may rotate at an angle larger than the first opening angle α. For example, the door 141 may be opened to a position at a right angle or higher relative to the outlet. At this time, since the cross-sectional area of the air passage is larger than that of the case of the first opening angle α, a more complex turbulent flow can be formed.

The door 141 opens and closes the dust passage hole 121a formed at the coupling part 140 and disposed between the dust container 220 and the flow path part 180 . The door 141 partially opens the dust passage hole 121a when the discharge cover 222 vibrates.

The door 141 may operate before at least one of the suction motor 214 and the dust collecting motor 191 operates.

In the additional dust collection step ( S60 ), the controller 400 may operate the door motor 142 to rotate the door 141 . At this time, the door 141 can be rotated to a position where the flow rate of the air sucked by the dust collection motor 191 can be changed (S61).

The additional dust collection step (S60) may be divided into at least two steps, and after the door unit 140 operates to change the passing area of the dust passing hole 121a (S61), the suction motor 214 or the dust collecting motor 191 operates to separate dust adsorbed on the discharge cover 222 (S62).

The door opening step (S40) performed before the above-described dust collection step (S50) may be referred to as a door completely opening step (S40) in order to be distinguished from the corresponding step (S61). This step (S61) may be referred to as a partial door opening step (S61) in order to be distinguished from the complete opening step (S40).

During the additional dust collection step ( S60 ), rotation to the first opening angle α or rotation to the second opening angle β may be alternately performed. Accordingly, airflow may be complicatedly changed to form turbulence, and dust adsorbed on the discharge cover 222 may be removed more effectively.

According to the door partial opening step (S61), as the door 141 operates, the size of the passage area of the dust passage hole 121a is changed. Accordingly, the flow rate at the outlet of the dust bin 220 is changed.

Referring to FIG. 15 , the passage area is an area formed by the dust passage hole 121a and the outer circumferential surface of the door 141 . The passage area has a triangular shape when viewed from one side, but has an annular shape when viewed from the front or rear.

The passing area area may vary between the first passing area area1 and the second passing area area2. The first passing area area1 is the passing area at the first opening angle α. The second passing area area2 is the passing area at the second opening angle β. The second passage area area2 is smaller than the first passage area area1.

The passing area may be related to the flow rate. For example, the flow rate of air in the second passage area area2 is faster than the flow rate of air in the first passage area area1.

During the additional dust collection step ( S60 ), the passage area (area) may be continuously varied between the first passage area (area1) and the second passage area (area2). Accordingly, airflow may be complicatedly changed to form turbulence, and dust adsorbed on the discharge cover 222 may be removed more effectively.

Specifically, when the passage area of the door 141 becomes the first passage area area 1 , the door 141 is stopped for a specific time or longer. Similarly, when the passage area of the door 141 becomes the second passage area area2, the door 141 is stopped for a specific time or longer. Accordingly, there is an effect that the flow of air can be changed more reliably than when the door 141 vibrates continuously without being stopped.

When the door arm 143 moves to the preset flow rate change position Pc, the door open/close detection unit 144 may detect this and transmit a signal corresponding thereto. Accordingly, the control unit 400 may determine that the door 141 has rotated to a position where the flow rate of air can be changed, and may stop the operation of the door motor 142 .

Alternatively, according to the embodiment, the control unit 400 determines that the door 141 has rotated to a position where the flow rate of air can be changed using the rotational speed of the door motor 142 and the operating time of the door motor 142. This may be determined, and the operation of the door motor 142 may be stopped.

In the additional dust collection step (S60), the door 141 may rotate within an angular range of 10 degrees or more and 90 degrees or less based on the closed position (Ps) blocking the dust passage hole (121a).

Specifically, referring to FIG. 15 , the door 141 is rotated from the closed position Ps to the open position Po in the door opening step S40 and then stopped, and in the dust collecting step S50 the open position Po ), and may be rotated to the flow rate change position (Pc) in the additional dust collection step (S60). In this case, an angle α from the closed position Pc to the open position Po may be greater than an angle β from the closed position Ps to the flow rate change position Pc. For example, the angle (α) from the closed position (Pc) to the open position (Po) may be 70 degrees or more and 90 degrees or less, and the angle (β) from the closed position (Ps) to the flow rate change position (Pc) is 10 It may be more than 35 degrees and less than 35 degrees. That is, the angle (α-β) from the open position (Pc) to the flow rate change position (Pc) may be 10 degrees or more and 90 degrees or less based on the closed position (Ps).

That is, referring to FIG. 15 , the discharge cover 222 may preferably vibrate at the flow rate change position Pc.

In the additional dust collection step (S60), the discharge cover 222 may be rotated in conjunction with the rotation of the door 141.

The discharge cover 222 may be rotated from the open position Po to the flow rate change position Ps. At this time, the position of the discharge cover 222 is an angle between one end of the dust box body 221 in the longitudinal direction (end toward the cleaner station) and the discharge cover 222 in a state where the dust box 220 is coupled to the cleaner station 100. can be expressed as Accordingly, a position of the discharge cover 222 when the dust container 220 is closed by being coupled to the dust container body 221 may be referred to as a cover closing position. And since the discharge cover 222 is rotated together in a state of contact with each other in conjunction with the rotation of the door 141, the open position Po and the flow rate change position Pc of the door 141 are the cover of the discharge cover 222. It can also be used for the open position and the cover flow rate change position.

Therefore, in the additional dust collection step (S60), the angle formed by the discharge cover 222 with one end of the dust box body 221 in the longitudinal direction at the cover flow rate change position is ) may be smaller than the angle formed with one end of the longitudinal direction. For example, at the cover flow rate change position Pc, the second rotation angle β between one end of the dust box body 221 in the longitudinal direction and the discharge cover 222 may be 10 degrees or more and 35 degrees or less, and the cover open position ( Po), a first rotational angle α formed between one end of the dust box body 221 in the longitudinal direction and the discharge cover 222 may be 40 degrees or more and 60 degrees or less. Alternatively, an angle between one end of the dust box body 221 in the longitudinal direction and the discharge cover 222 may be temporarily greater than or equal to the first rotational angle α and less than or equal to 90 degrees.

Therefore, in the additional dust collection step ( S60 ), the open area of the dust passage hole 121a may be changed while the door 141 rotates before the suction motor 214 operates. In addition, in the additional dust collection step (S60), the area in which the inner space of the dust bin 220 is opened may also be changed.

With this configuration, in the additional dust collection step (S60), the flow rate of air passing through the dust passage hole 121a may be changed. Specifically, the flow rate of air passing through the dust passage hole 121a in the additional dust collection step ( S60 ) may be higher than the flow rate of air passing through the dust passage hole 121a in the dust collection step ( S50 ). That is, in the present embodiment, the flow rate of air passing through the dust passage hole 121a is maintained while the open area of the dust passage hole 121a changes, so the flow rate of air passing through the dust passage hole 121a changes.

The door 141 may be operated before the dust collecting motor 191 operates in the dust collecting step (S50) to completely open the dust passage hole 121a. In addition, after the dust passage hole 121a is completely opened, and before the dust collection motor 191 or the suction motor 214 operates in the additional dust collection step (S60), the door 141 operates to remove the dust passage hole 121a. can only partially open. The dust passage hole 121a is completely opened in the dust collecting step (S50). Accordingly, a large amount of dust passes through the dust passage hole 121a and flows into the cleaner station 100 . On the other hand, the dust passage hole 121a is partially opened in the additional dust collection step (S60). Accordingly, since the dust is sucked in at a high flow rate, the dust adsorbed on the discharge cover 222 can be separated more effectively.

In the additional dust collection step (S60), the discharge cover 222 receives a suction force from the dust collection motor 191 in the direction in which the discharge port is opened. In addition, the discharge cover 222 receives an elastic force from the vibration spring 141d in a direction in which the discharge port is closed. The suction force and the elastic force cause the discharge cover 222 to vibrate, and as the discharge cover 222 vibrates, dust adsorbed to the discharge cover 22 may be removed.

In the additional dust collection step ( S60 ), at least one of the suction power Fa of the suction motor 214 and the suction force Fb of the dust collecting motor 191 may be variable. And, the discharge cover 222 is vibrated by the suction force of at least one of the suction motor 214 and the dust collecting motor 191 .

The additional dust collecting step (S60) may be divided into a step (S62) of operating the suction motor 214 and/or the dust collecting motor 191 after the partial door opening step (S61) is performed (see FIG. 13).

In the additional dust collection step (S60), the dust collection motor 191 may operate. The dust collection motor 191 generates a suction force Fb during the additional dust collection time ts2. The suction force Fb generated from the dust collecting motor 191 generates air flow. The suction force Fb generated by the dust collecting motor 191 is provided to the dust bin 220, and the dust collected in the dust bin 220 is sucked in and moved to the dust collecting part 170 through the passage part 180. The suction force Fb generated by the dust collecting motor 191 is applied to the discharge cover 222 and moves the discharge cover 222 in a direction in which the dust bin 220 is opened. The direction in which the dust bin 220 is opened corresponds to a counterclockwise direction in FIG. 9 .

At this time, the control unit 400 may gradually increase the rotation speed of the dust collecting motor 191 up to the preset dust collection speed for a preset suction increase time (not shown). This has the advantage of increasing the lifetime of the dust collecting motor 191 by protecting the dust collecting motor 191 .

At this time, the control unit 400 may gradually decrease the rotational speed of the dust collecting motor 191 for a preset suction reduction time tsd. This has the advantage of increasing the lifetime of the dust collecting motor 191 by protecting the dust collecting motor 191 . Alternatively, the control unit 400 may immediately cut off power applied to the dust collecting motor 191 . This has the advantage of minimizing the operation time of the dust collecting motor 191, increasing energy efficiency and minimizing noise generation.

In the additional dust collection step (S60), the suction motor 214 may operate. The suction motor 214 generates suction power Fa during the additional dust collection time ts2. The suction force Fa generated by the suction motor 214 generates air flow. The suction force Fa generated by the suction motor 214 is provided to the dust bin 220 , and dust remaining around the outlet of the dust bin 220 may be recovered into the dust bin 220 . The suction force Fa generated by the suction motor 214 is applied to the discharge cover 222 and moves the discharge cover 222 in a direction in which the dust container 220 is closed. The direction in which the dust bin 220 is closed corresponds to the clockwise direction (CW) in FIG. 9 .

At this time, the controller 400 may gradually increase the rotational speed of the suction motor 214 up to a preset suction speed during a preset suction increase time (not shown). This has the advantage of increasing the lifetime of the suction motor 214 by protecting the suction motor 214 .

At this time, the control unit 400 may gradually reduce the rotational speed of the suction motor 214 for a preset suction reduction time tsd. This has the advantage of increasing the lifetime of the suction motor 214 by protecting the suction motor 214 . Alternatively, the controller 400 may immediately cut off power applied to the suction motor 214 . This has the advantage of minimizing the operation time of the suction motor 214, increasing energy efficiency and minimizing noise generation.

In the additional dust collection step (S60), the door motor 142 may operate. The door motor 142 may drive the door 141 to change the area of the dust passage hole 121a, and increase the flow rate by reducing the area of the dust passage hole 121a, thereby removing remaining dust easily. make it move

The door motor 142 may operate when the additional dust collecting step ( S60 ) starts, and may stop before the suction motor 214 and the dust collecting motor 191 operate. However, unlike that shown in FIG. 12 , the door motor 142 may operate while the suction motor 214 or the dust collecting motor 191 is operating.

Meanwhile, in the control method of the cleaner station 100 according to an embodiment of the present invention, after the operation of the dust collecting motor 191 is finished, the door 141 is rotated to open at least a part of the dust passage hole 121a. Then, a door closing confirmation step (S70) of re-blocking may be further included.

Specifically, the control unit 400 may rotate the door motor 142 in a forward direction and then in a reverse direction when a preset suction end time tse elapses after the operation of the dust collecting motor 191 is finished.

For example, the control unit 400 moves the door motor 142 in the forward direction when a time of 3 seconds or more and 11 seconds or less, preferably 9 seconds or more and 11 seconds or less has elapsed after the operation of the dust collecting motor 191 is finished. By operation, the door 141 can be rotated to the flow rate change position Pc. After that, the controller 400 may operate the door motor 142 in a reverse direction to rotate the door 141 to the closed position Ps.

This is because in the additional dust collection step (S60), since the dust collection motor 191 is operated in a state in which the dust passage hole 121a is closed, the dust passage hole 121a is finely formed by the sound pressure generated by the operation of the dust collection motor 191. This is to prevent it from being open. Therefore, according to the door closing confirmation step (S70), after the operation of the dust collection motor 191 is finished, the door 141 once again blocks the dust passage hole 121a to remove dust that may exist on the flow path portion 180. It has the effect of preventing backflow.

In the fixing releasing step ( S80 ), when the door 141 is closed, the fixing motor 133 may be operated to release the fixing of the dust container 220 by the fixing member 131 .

In detail, the control unit 400 may release the fixation of the dust bin 220 when receiving a signal from the door opening/closing detection unit 144 that the door 141 blocks the dust passing hole 121a.

That is, when the door arm 143 moves to the preset door closing position DP2, the door opening/closing detection unit 144 may detect this and transmit a signal for this. Accordingly, the control unit 400 may determine that the door 141 blocks the dust passage hole 121a and may operate the fixing unit motor 133 in a reverse direction to release the fixation of the dust container 220 .

Alternatively, according to the embodiment, the control unit 400 may detect that the door 141 has rotated sufficiently to block the dust passage hole 121a through the current value applied to the door motor 142, based on this. It may be determined that the furnace door 141 blocks the dust passage hole 121a, and the fixing part motor 133 may be operated in a reverse direction to release the fixation of the dust container 220.

In this case, when the fixing member 131 or the fixing part link 135 moves to the fixing releasing position FP2, the fixing detecting unit 137 may transmit a signal indicating that the fixing of the cleaner 200 is released.

Accordingly, the control unit 400 may receive a signal indicating that the fixation of the cleaner 200 is released from the fixation detection unit 137 and determine that the fixation of the cleaner 200 is released.

When it is determined that the fixation of the cleaner 200 is released, the control unit 400 may stop the operation of the motor 133 of the fixing unit.

Unlike this, according to an embodiment, the controller 400 may operate the door motor 142 for a preset time. For example, the controller 400 may stop the operation of the door motor 142 after operating the door motor 142 in the reverse direction for a period of 4 seconds or more and 5 seconds or less.

Hereinafter, each component driven in the additional dust collection step (S60) will be described in detail.

Referring to FIG. 6 , the vibration spring 141d is one of the components that provide the discharge cover 222 with a force for vibrating the discharge cover 222 .

The elastic modulus of the vibration spring 141d may be sufficiently low. The elastic coefficient may be set so that the elastic force Fc provided to the discharge cover 222 by the vibration spring 141d is equal to the suction force Fb provided to the discharge cover 222 by the dust collection motor 191 . In this case, the elastic force (Fc) and the suction force (Fb) applied to the discharge cover 222 are the same, and even if the dust collection motor 191 is not controlled, according to the minute change in the air flow inside the flow path 180, the discharge cover (222) can be vibrated.

The vibration spring 141d is disposed on the door 141 and provides an elastic force Fc to the discharge cover 222 in a direction in which the discharge port is closed. By having this arrangement, when the dust collecting motor 191 provides a strong suction force Fb to the discharge cover 222, the vibration spring 141d is compressed to the maximum so that the discharge cover 222 collides with the door 141 and , dust adsorbed to the discharge cover 222 may be separated by the collision.

When the door 141 is formed in a shape similar to a circle, the vibration spring 141d is disposed at the center of the circle.

An insertion groove into which at least a part of the vibration spring 141d is inserted is formed in the door 141, and the vibration spring 141d is inserted into the insertion groove to fix its position. A part of the vibration spring 141d may be inserted into the insertion groove, and the remaining part may protrude out of the door 141 .

A vibration spring 141d cover is disposed at an outer end of the vibration spring 141d. The cover of the vibration spring 141d may be formed in a cup-shape. One side of the cover of the vibration spring 141d is opened, and at least a part of the vibration spring 141d is inserted.

The other end of the vibration spring 141d is disposed adjacent to the discharge cover 222 . More specifically, the other end of the vibration spring 141d faces the vibration spring support member 222e of the discharge cover 222 .

The vibration spring 141d is disposed to be inserted into the door 141. When the vibration spring 141d is inserted into the door 141 as much as possible, an end of the vibration spring 141d may be disposed on an inner surface of the door 141 and a straight line.

The dust collecting motor 191 provides a suction force Fb to the discharge cover 222 in a direction in which the discharge port is opened. The direction in which the dust bin 220 is opened corresponds to a counterclockwise direction (CCW) in FIG. 9 . According to one embodiment, the discharge cover 222 may vibrate by the vibration spring 141d and the dust collection motor 191 . Referring to FIG. 9 , the dust collection motor 191 provides a suction force Fb to the discharge cover 222 in a counterclockwise direction, and the vibration spring 141d applies an elastic force Fc to the discharge cover 222 in a clockwise direction. to provide. Accordingly, when the suction force (Fb) of the dust collecting motor 191 increases, the vibration spring 141d is compressed, the discharge cover 222 rotates counterclockwise, and the suction force (Fb) of the dust collecting motor 191 decreases. In this case, the vibration spring 141d is extended and the discharge cover 222 rotates clockwise. Therefore, when the suction force Fb of the dust collecting motor 191 increases or decreases repeatedly, the discharge cover 222 vibrates. As the discharge cover 222 vibrates, the dust adsorbed to the discharge cover 222 is separated and collected by the dust collection unit 170 by the suction force Fb of the dust collection motor 191 .

The suction motor 214 provides a suction force Fa to the discharge cover 222 in a direction in which the discharge port is closed. The direction in which the dust bin 220 is closed corresponds to the clockwise direction (CW) in FIG. 9 . According to the above-described embodiment, when the discharge cover 222 vibrates, the degree of vibration by the suction motor 214 may be changed. Referring to FIG. 9 , the suction motor 214 provides a suction force Fa to the discharge cover 222 in a clockwise direction, which is opposite to the direction of the suction force Fa provided by the dust collecting motor 191 . Accordingly, when the suction force Fa of the suction motor 214 increases, the vibration spring 141d extends and the discharge cover 222 rotates clockwise, and the suction force Fa of the suction motor 214 decreases. In this case, the vibration spring 141d is compressed and the discharge cover 222 rotates clockwise. Therefore, when the suction force Fa of the suction motor 214 increases or decreases repeatedly, the discharge cover 222 vibrates. When the discharge cover 222 vibrates, the suction force Fa of the suction motor 214 is applied to the inner surface of the discharge cover 222, so dust adsorbed on the discharge cover 222 can be separated more easily. .

The torsion spring 222d is disposed on the hinge portion 222b of the discharge cover 222 and provides an elastic force Fd to the discharge cover 222 in a direction in which the discharge port is opened. According to the above-described embodiment, when the discharge cover 222 vibrates, the degree of vibration may be changed by the torsion spring 222d. Referring to FIG. 9, the torsion spring 222d provides an elastic force Fd to the discharge cover 222 in a counterclockwise direction (CCW), which is opposite to the direction of the elastic force Fc provided by the vibration spring 141d. do. Accordingly, the torsion spring 222d cancels the elastic force Fd of the vibration spring 141d to some extent, and even when the fluctuation range of the suction force Fb of the dust collecting motor 191 is small, a sufficient vibration range can be secured.

According to an embodiment different from the above-described embodiment, the discharge cover 222 may vibrate by the torsion spring 222d and the suction motor 214. That is, the torsion spring 222d provides elastic force (Fd) to the discharge cover 222 in the direction in which the discharge port is opened, and the suction motor 214 applies the suction force (Fa) to the discharge cover 222 in the direction in which the discharge port is closed. provides Referring to FIG. 9 , the suction motor 214 provides a suction force Fa to the discharge cover 222 in a clockwise direction, and the torsion spring 222d applies an elastic force Fd to the discharge cover 222 in a counterclockwise direction. to provide. Accordingly, when the suction force Fa of the suction motor 214 increases, the torsion spring 222d compresses and the discharge cover 222 rotates clockwise, and the suction force Fa of the suction motor 214 decreases. In this case, the torsion spring 222d is extended and the discharge cover 222 rotates counterclockwise. Therefore, when the suction force Fa of the suction motor 214 increases or decreases repeatedly, the discharge cover 222 vibrates. Therefore, as the discharge cover 222 vibrates, dust adsorbed to the discharge cover 222 may be separated.

According to an embodiment different from the above-described embodiment, the discharge cover 222 may vibrate by the suction motor 214 and the dust collecting motor 191 . That is, the direction of the suction force Fa provided to the discharge cover 222 by the suction motor 214 is opposite to the direction of the suction force Fb provided to the discharge cover 222 by the dust collecting motor 191 . Referring to FIG. 9 , the dust collecting motor 191 provides a suction force Fb to the discharge cover 222 in a counterclockwise direction, and the suction motor 214 applies a suction force Fa to the discharge cover 222 in a clockwise direction. to provide. Accordingly, when the suction force (Fb) of the dust collecting motor 191 is greater than the suction force (Fa) of the suction motor 214, the discharge cover 222 rotates counterclockwise, and the suction force (Fb) of the dust collecting motor 191 When the suction force Fa of the suction motor 214 is smaller than that, the discharge cover 222 rotates clockwise. Accordingly, the discharge cover 222 vibrates as the suction force of the dust collecting motor 191 and the suction motor 214 is changed. Therefore, as the discharge cover 222 vibrates, the dust adsorbed to the discharge cover 222 is separated and collected in the dust collection unit 170 by the suction force Fb of the dust collection motor 191 .

At least one of the suction motor 214 and the dust collection motor 191 may be controlled as the rotational speed is changed. Hereinafter, a method of controlling the suction motor 214 and/or the dust collecting motor 191 according to each embodiment will be described.

The rotational speed value of the dust collecting motor 191 may include a first dust collecting speed Ws1 and a second dust collecting speed Ws2. At this time, the second dust collection speed (Ws2) is smaller than the first dust collection speed (Ws1).

Referring to FIG. 17, the additional dust collection step (S60) according to the first embodiment will be described.

Referring to FIG. 17 , the dust collection motor 191 may have a first dust collection speed Ws1 and a second dust collection speed Ws2 alternately. At this time, when the rotational speed is changed, the rotational speed is continuously changed for a predetermined time.

The control unit 400 may gradually change the rotational speed of the dust collecting motor 191 between the first dust collecting speed Ws1 and the second dust collecting speed Ws2 for a preset time period tb. For example, the control unit 400 may gradually reduce the rotational speed of the dust collecting motor 191 from the first dust collecting speed Ws1 to the second dust collecting speed Ws2, and conversely, the second dust collecting speed Ws2. It can be gradually increased to 1 dust collection speed (Ws1). This has the advantage of increasing the lifetime of the dust collecting motor 191 by protecting the dust collecting motor 191 .

Unlike shown in FIG. 17A, referring to FIG. 17B, the suction motor 214 may also operate while the dust collection motor 191 operates. At this time, the rotation speed of the suction motor 214 may be smaller than the first dust collection speed Ws1. In the case of FIG. 17B , since the air flow direction is changed as the suction motor 214 operates, there is an advantage in that dust adsorbed on the discharge cover 222 can be separated more effectively.

Hereinafter, the additional dust collection step (S60) according to the second embodiment will be described with reference to FIG. 18.

The additional dust collecting step (S60) according to the second embodiment may be used as long as it does not conflict with the description of the additional dust collecting step (S60) according to the first embodiment. Hereinafter, the additional dust collecting step (S60) according to the second embodiment will be described focusing on differences from the additional dust collecting step (S60) according to the first embodiment.

Referring to FIG. 18 , the dust collection motor 191 may have a first dust collection speed Ws1 and a second dust collection speed Ws2 alternately. At this time, when the rotational speed is changed, it is turned off for a predetermined time.

Referring to FIG. 18A , the rotational speed value of the dust collecting motor 191 may include a first dust collecting speed Ws1 and a second dust collecting speed Ws2. At this time, the second dust collection speed Ws2 is greater than the first dust collection speed Ws1. The first dust collecting speed Ws1 and the second dust collecting speed Ws2 of the dust collecting motor 191 appear alternately, and may be turned off for a predetermined time before the rotational speed is changed.

According to the second embodiment, since the dust collecting motor 191 is stopped or operated at the first dust collecting speed Ws1 or at the second dust collecting speed Ws2, the suction force Fb of the dust collecting motor 191 is at least three stages. As it fluctuates three-dimensionally, the dust adsorbed on the discharge cover 222 can be efficiently separated.

Unlike shown in FIG. 18A, referring to FIG. 18B, the suction motor 214 may be operated while the suction motor 214 is turned off. In FIG. 18A, no external force acts on the dust adsorbed to the discharge cover 222 while the dust collecting motor 191 is stopped, but in FIG. 18B, the external force is applied to the dust adsorbed while the dust collecting motor 191 is stopped in the opposite direction. Therefore, the dust adsorbed on the discharge cover 222 can be separated more effectively.

Hereinafter, the additional dust collection step (S60) according to the third embodiment will be described with reference to FIG. 19 .

The additional dust collecting step (S60) according to the third embodiment may be used as long as it does not conflict with the description of the additional dust collecting step (S60) according to the above-described first and second embodiments. Hereinafter, the additional dust collecting step (S60) according to the third embodiment will be described focusing on the difference from the additional dust collecting step (S60) according to the first and second embodiments.

According to the third embodiment, the dust collection motor 191 is continuously operated, and the suction motor 214 can be controlled by being turned on and off. That is, the suction motor 214 may be operated intermittently. Accordingly, according to the third embodiment, the discharge cover 222 can be vibrated by on/off controlling the suction motor 214 .

Furthermore, the rotational speed of the suction motor 214 is faster than the rotational speed of the dust collecting motor 191, and the suction force Fa of the suction motor 214 is greater than the suction force Fb of the dust collecting motor 191. Accordingly, when the suction motor 214 and the dust collection motor 191 operate simultaneously, the flow direction is switched from the cleaner station 100 to the dust bin 220 . That is, since the air flow direction is changed according to the on/off of the suction motor 214, there is an advantage in that dust adsorbed on the discharge cover 222 can be separated more effectively.

Referring to FIG. 19 , the suction motor 214 may start operating after the dust collection motor 191 operates when the driving mode is changed. Alternatively, unlike FIG. 19 , the suction motor 214 may start operating before the dust collection motor 191 operates when the operation mode is changed. Changing the operation mode means that the dust collection step (S50) ends and the additional dust collection step (S60) starts.

Referring to FIG. 19 , the suction motor 214 may operate in a pulsed fashion. At this time, the control unit 400 may control the suction motor 214 on/off by applying a voltage to the suction motor 214 in a pulse form.

Hereinafter, the additional dust collection step (S60) according to the fourth embodiment will be described with reference to FIG. 20 .

The additional dust collecting step (S60) according to the fourth embodiment may be used as long as it does not conflict with the description of the additional dust collecting step (S60) according to the above-described first to third embodiments. Hereinafter, the additional dust collecting step (S60) according to the fourth embodiment will be described focusing on differences from the additional dust collecting step (S60) according to the first to third embodiments.

According to the fourth embodiment, the dust collecting motor 191 is controlled by being turned on and off, and the suction motor 214 may continuously operate. That is, the dust collecting motor 191 may be operated intermittently. Accordingly, according to the fourth embodiment, the discharge cover 222 may be vibrated by on/off controlling the dust collecting motor 191 .

Furthermore, when the dust collection motor 191 does not operate, the flow direction is switched from the cleaner station 100 to the dust bin 220 . That is, since the air flow direction is changed according to the on/off of the dust collection motor 191, there is an advantage in that dust adsorbed on the discharge cover 222 can be separated more effectively.

Referring to FIG. 20 , the suction motor 214 may start operating after the dust collection motor 191 operates when the driving mode is changed. Alternatively, unlike FIG. 20 , the suction motor 214 may start operating before the dust collection motor 191 operates when the operation mode is changed.

Referring to FIG. 20 , the dust collection motor 191 may operate in a pulse form. At this time, the control unit 400 may control the dust collecting motor 191 on/off by applying a voltage to the dust collecting motor 191 in a pulse form.

Hereinafter, a cleaner system 10 according to another embodiment will be described. The cleaner system 10 to be described below may be used within a range that does not conflict with the above description. Hereinafter, the cleaner system 10 according to the present invention will be described.

The cleaner system 10 according to the present embodiment includes a cleaner 200 and a cleaner station 100 to which the cleaner 200 is coupled. The cleaner 200 includes a dust bin 220 that collects dust and has an outlet formed on one side. The cleaner station 100 is disposed in the inner space of the housing 110 and includes a flow path 180 communicating with the dust container 220 . The cleaner station 100 includes a door 141 formed at the coupling part 120 and opening and closing the dust passage hole 121a disposed between the dust bin 220 and the flow path part 180 . The door 141 alternately performs a complete opening step and a partial opening step.

The full opening step and the partial opening step are as described above. That is, in the fully open step, the door 141 rotates and moves to the open position Po, and in a partial open step, the door 141 rotates and moves to the flow rate change position Pc.

In this embodiment, the additional dust collection step (S60) includes both a full open step and a partial open step, and may be performed by alternating a full open step and a partial open step. As a result, the air flow in the passage part 180 irregularly fluctuates, and dust adsorbed on the discharge cover 222 can be effectively removed. Alternatively, the additional dust collection step (S60) may include only a partial opening step.

In this embodiment, the cleaner station 100 may further include a vibration spring 141d. The vibration spring 141d is disposed on one side of the discharge cover 222 covering the outlet of the dust bin 220 and provides an elastic force Fc to the discharge cover 222 in one direction. The aforementioned one direction refers to a direction in which the outlet is closed. According to the present embodiment, when the door 141 moves between the open position Po and the flow rate change position Pc, elastic force Fc is provided to the discharge cover 222 to vibrate the discharge cover 222. can

According to this embodiment, the cleaner 200 includes a torsion spring 222d. The torsion spring 222d is disposed on one side of the discharge cover 222 and provides the elastic force Fd to the discharge cover 222 in the opposite direction to the elastic force Fc provided by the vibration spring 141d. According to the present embodiment, the torsion spring 222d offsets the elastic force Fc of the vibration spring 141d to some extent, so that a sufficient vibration width can be secured even when the pressure change of the flowing air is small.

Air pressure inside the flow path part 180 may be determined by the dust collection motor 191 and the suction motor 214 . The dust collecting motor 191 is disposed in the cleaner station 100 and provides a suction force Fb to the discharge cover 222 in the same direction as the direction of the elastic force Fd of the torsion spring 222d. The suction motor 214 is disposed in the cleaner and provides suction force Fa to the discharge cover 222 in the same direction as the direction of the elastic force Fc of the vibration spring 141d. That is, the suction force (Fb) of the dust collecting motor 191 and the suction force (Fa) of the suction motor 214 fluctuate individually, and the pressure of the air flowing inside the flow path part 180 is the suction force of the dust collecting motor 191. It can be determined by the difference between (Fb) and the suction force (Fa) of the suction motor 214. In other words, the pressure of the air flowing inside the flow path part 180 may be determined by the difference between the rotational speed of the dust collection motor 191 and the rotational speed of the suction motor 214 .
