Description

Vacuum cleaner system

[0001] The present invention relates to a vacuum cleaner system.

[0002]

[0003] In general, a vacuum cleaner is a home appliance that uses electricity to suck up air and fills a dust bin inside the product with small pieces of trash or dust. It is commonly called a vacuum cleaner.

[0004] These vacuum cleaners can be categorized into manual vacuum cleaners, which the user moves to clean, and automatic vacuum cleaners, which clean by moving around on their own. Manual vacuum cleaners can be categorized by type, including canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0005] In the past, canister-type vacuum cleaners were widely used in household vacuum cleaners, but recently, handheld vacuum cleaners and stick vacuum cleaners that provide the dust bin and vacuum cleaner body as an integrated unit, which improves convenience, are being widely used.

[0006] Canister-type vacuum cleaners have a main body and suction inlet connected by a rubber hose or pipe, and in some cases, a brush can be inserted into the suction inlet for use.

[0007] Handheld vacuum cleaners maximize portability. They are lightweight, but their short length limits the cleaning area they can be used in while seated. Therefore, they are used for cleaning small areas, such as desks, sofas, or inside cars.

[0008] Stick vacuums can be used standing up, allowing for cleaning without bending down. This makes them ideal for moving around and cleaning large areas. While handheld vacuums are suitable for cleaning tight spaces, stick vacuums can clean wider areas and reach high, out-of-reach places. Recently, stick vacuums have been offered in modular configurations, allowing users to actively adapt the vacuum to suit a variety of applications.

[0009] Recent vacuum cleaners are trending toward miniaturization to maximize portability. Consequently, the dustbins of recently produced vacuum cleaners have been small, requiring users to frequently empty them, a cumbersome process.

[0010] To address the aforementioned inconvenience, a vacuum cleaner station was developed. A vacuum cleaner station is a device that holds a vacuum cleaner after cleaning and sucks up the dust collected by the vacuum cleaner. In other words, the dust collected by the vacuum cleaner is continuously captured in the vacuum cleaner station's dust collection compartment, and the user empties the dust collection compartment. This significantly reduces the number of times the user has to empty the dust bin, compared to emptying the vacuum cleaner's dust bin every time.

[0011] Meanwhile, Korean Patent Publication No. 10-2022-0115253 discloses a cleaning device including a vacuum cleaner and a docking station.

[0012] The above prior art patent document discloses a filter capable of filtering ultrafine dust and other particles not filtered by the multi-cyclone within the dustbin. However, since the filter is positioned within the filter housing at the top of the dustbin, it is difficult for a user to easily remove and clean the filter. In other words, to clean the filter, the user must first remove the dustbin and then remove the filter from the filter housing, which is cumbersome.

[0013] Likewise, in order for the user to clean the multi-cyclone, there is also the inconvenience of having to first open or separate the dustbin and then separate the multi-cyclone from the dustbin.

[0014] At this time, the above prior art patent document may be provided with a flow rate change device. The flow rate change device is configured to selectively change the amount of suction air supplied to the dustbin so that the flow rate of air inside the dustbin changes when the suction device of the docking station is operated. That is, the flow rate change device is configured to change the flow rate itself supplied to the dustbin periodically by repeatedly supplying and blocking outside air to the dustbin by supplying air to the dustbin for a predetermined period of time and then blocking the supply of air for a predetermined period of time.

[0015] However, the above prior art patent document is configured to change the flow rate itself supplied to the inside of the dustbin by having a separate flow rate change device repeatedly open and close the flow path between the collection unit and the suction unit, so although it can strongly suck up large dust accumulated inside the dustbin, it has limitations in removing dust accumulated in the filter placed at the top of the dustbin and the multi-cyclone placed inside the dustbin.

[0016]

[0017] The present invention was created to improve the problems described above, and the object of the present invention is to provide a vacuum cleaner system that can easily remove dust accumulated in a filter and a second cyclone section without separating the components of the vacuum cleaner.

[0018] In addition, the present invention aims to provide a vacuum cleaner system in which suction airflow can be intensively delivered to a second dust storage unit when a dust collecting motor of a vacuum cleaner station is driven.

[0019] In addition, the present invention aims to provide a vacuum cleaner system capable of sealing a second dust storage compartment when the dust collecting motor of the vacuum cleaner station is not driven.

[0020] In addition, the present invention aims to solve the problem of providing a vacuum cleaner system capable of sucking up dust accumulated in a filter and a second cyclone section by transmitting suction air current generated from a dust collecting motor of a vacuum cleaner station to a filter and a second cyclone section.

[0021] In addition, the present invention aims to solve the problem of providing a vacuum cleaner system in which the suction air flow flowing into the second dust storage unit can be uniformly transmitted.

[0022] In addition, the present invention aims to solve the problem of providing a vacuum cleaner system in which a valve member for opening and closing a dust discharge port is moved along the length direction of a dust bin so that all edge areas of the dust discharge port are connected to a flow path without being interfered with by a separate member.

[0046]

[0047] As described above, the vacuum cleaner system according to the present invention has the effect of maintaining the sanitary condition inside the vacuum cleaner clean without separating the components of the vacuum cleaner by allowing the suction air flow to be intensively delivered to the filter and second cyclone section of the vacuum cleaner.

[0048] In addition, the present invention has the effect of effectively removing dust accumulated inside the filter and the second cyclone section by delivering suction airflow only to the second dust storage section while the first dust storage section is closed.

[0049] In addition, the present invention has the effect of sealing the second dust storage unit when the dust collecting motor is not driven, since the valve member receives elastic force in the direction of closing the second dust storage unit.

[0082] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0083] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. This is not intended to limit the invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0084] The terminology used in this application is solely for the purpose of describing specific embodiments and is not intended to limit the present invention. Singular expressions may include plural expressions, unless the context clearly dictates otherwise.

[0085] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Terms defined in commonly used dictionaries, such as those defined in the present application, may be interpreted to have a meaning consistent with their meaning in the context of the relevant technology, and, unless explicitly defined herein, may not be interpreted in an idealized or overly formal sense.

[0086]

[0087] FIG. 1 is a perspective view of a cleaner system comprising a cleaner station and a cleaner according to an embodiment of the present invention, and FIGS. 2 to 4 are schematic diagrams of the configuration of a cleaner system according to various embodiments of the present invention.

[0088] Referring to FIGS. 1 and 2, a cleaner system (10) according to an embodiment of the present invention may include a cleaner station (100) and a cleaner (200).

[0089] The vacuum cleaner system (10) may include a vacuum cleaner station (100). A vacuum cleaner (200) may be coupled to the vacuum cleaner station (100). Specifically, a main body of the vacuum cleaner (200) may be coupled to a side of the vacuum cleaner station (100). The vacuum cleaner station (100) may remove dust from a dust bin (220) of the vacuum cleaner (200).

[0090]

[0091] Meanwhile, FIG. 5 shows an exploded view of a vacuum cleaner according to an embodiment of the present invention.

[0092] The structure of the vacuum cleaner (200) is described below with reference to Fig. 5.

[0093] The vacuum cleaner (200) may refer to a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (200) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0094] The cleaner (200) can be mounted on the cleaner station (100). The cleaner (200) can be supported by the cleaner station (100). The cleaner (200) can be coupled to the cleaner station (100).

[0095] Meanwhile, in one embodiment of the present invention, the direction of the vacuum cleaner (200) can be defined based on the time when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

[0096] At this time, the front may refer to the direction in which the suction unit (212) is arranged based on the suction motor (216), and the rear may refer to the direction in which the handle (218) is arranged based on the suction motor (216). In addition, when looking at the suction unit (212) from the suction motor (216), the direction in which it is arranged on the right may be referred to as the right, and the direction in which it is arranged on the left may be referred to as the left. In addition, in one embodiment of the present invention, the upper and lower sides may be defined along the direction perpendicular to the ground when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

[0097] The vacuum cleaner (200) may include a main body (210). The main body (210) may include a main body housing (211), a suction unit (212), a cyclone unit (213), a filter unit (214), a storage member (215, 1215), a suction motor (216), an air discharge cover (217), a handle (218), and an operating unit (219).

[0098] The main body housing (211) may form the exterior of the vacuum cleaner (200). The main body housing (211) may provide a space capable of accommodating a suction motor (216) and a filter (270) therein. The main body housing (211) may be configured in a shape similar to a cylinder.

[0099] The suction part (212) may protrude outwardly from the main body housing (211). For example, the suction part (212) may be formed in a cylindrical shape with an open interior. The suction part (212) may be coupled to an extension pipe (250). The suction part (212) may provide a path (hereinafter, referred to as a 'suction path') through which air containing dust may flow.

[0100] Meanwhile, in the present embodiment, a virtual line penetrating the interior of the suction part (212) configured in a cylindrical shape can be formed. The virtual line penetrating the interior of the suction part (212) can mean the longitudinal axis (a1) of the suction path.

[0101]

[0102] The cyclone section (213) is a configuration that applies the principle of a dust collector that uses centrifugal force to separate dust sucked into the inside of the dust bin (220) through the suction section (212). At least one cyclone section (213) is provided to separate dust by cyclone flow.

[0103] The cyclone unit (213) may include a first cyclone unit (213a) placed inside the dust bin (220) and a second cyclone unit (213b) placed inside the first cyclone unit (213a).

[0104] The first cyclone section (213a) can be connected to the suction section (212). The first cyclone section (213a) is configured to apply the principle of a dust collector that uses centrifugal force to separate dust sucked into the interior of the dust bin (220) through the suction section (212).

[0105] The first cyclone section (213a) may refer to a space where a cyclone flow that rotates along the inner surface of the dust bin (220) occurs. The first cyclone section (213a) may refer to a portion of the space inside the dust bin (220).

[0106] Air and dust sucked through the suction part (212) flow along the inner surface of the first cyclone part (213a), thereby allowing cyclonic flow to occur in the inner space of the cyclone part (213).

[0107] The cyclone flow generated in the first cyclone section (213a) may be due to the suction force of the suction motor (216). The cyclone flow generated in the first cyclone section (213a) may be formed between the inner side of the dust bin (220) and the outer side of the filter body (214a). The cyclone flow generated in the first cyclone section (213a) may be formed between the inner surface of the cyclone section (213) and the outer surface of the filter body (214a).

[0108] At this time, the axis (a2) of the cyclone flow generated in the first cyclone section (213a) and the axis (a2) of the cyclone flow generated in the second cyclone section (213b) can extend in the vertical direction. That is, the axis (a2) of the cyclone flow generated in the first cyclone section (213a) and the axis (a2) of the cyclone flow generated in the second cyclone section (213b) can form a coaxial line in the vertical direction, which can be collectively referred to as the axis (a2) of the cyclone flow of the cyclone section (213).

[0109] For example, the cyclone flow generated in the first cyclone section (213a) may be formed to surround in a circular shape along the inner circumference of the dustbin (220) or the outer circumference of the filter body (214a) described later. That is, the air sucked in through the suction section (212) flows in a circular shape along the inner circumference of the dustbin (220) or the outer circumference of the filter body (214a) based on the central axis (a3) ​​of the dustbin, thereby allowing a cyclone flow to occur in the internal space of the cyclone section (213).

[0110] Specifically, when the axis (a2) of the cyclone flow is arranged vertically downward in the direction of gravity, the air sucked through the suction unit (212) can flow in a circular shape along the inner perimeter of the dustbin (220) or the inner perimeter of the filter body (214a) based on the central axis (a3) ​​of the dustbin. In other words, when the axis (a2) of the cyclone flow is arranged parallel to the ground, the air sucked through the suction unit (212) can flow in a circular shape along the inner perimeter of the dustbin (220) or the inner perimeter of the filter body (214a) based on the central axis (a3) ​​of the dustbin.

[0111] As another example, the cyclone flow generated in the first cyclone section (213a) may be formed in a spiral shape along the inner circumference of the dustbin (220) or the outer circumference of the filter body (214a). That is, the air sucked in through the suction section (212) flows in a spiral shape along the inner circumference of the dustbin (220) or the outer circumference of the filter body (214a), thereby allowing a cyclone flow to be generated in the internal space of the first cyclone section (213a).

[0112] Specifically, when the axis (a2) of the cyclone flow is arranged to be inclined with respect to the ground, the air sucked through the suction part (212) can flow in a spiral shape along the inner circumference of the dust bin (220) or the outer circumference of the filter body (214a).

[0113] Meanwhile, the cyclone unit (213) may include a second cyclone unit (213b) that separates dust from air that has passed through the first cyclone unit (213a). Specifically, the second cyclone unit (213b) may separate dust again from air discharged from the first cyclone unit (213a).

[0114] At this time, the second cyclone unit (213b) may be positioned inside the first cyclone unit (213a) so as to minimize the size of the vacuum cleaner (200). The second cyclone unit (213b) may be positioned below the suction motor (216). Specifically, the second cyclone unit (213b) may be positioned inside the filter unit (214). That is, the cyclone unit (213) and the second cyclone unit (213b) may be positioned inside the dust bin (220) with the filter unit (214) interposed therebetween.

[0115] The second cyclone unit (213b) may include a plurality of cyclone bodies (213ba) arranged in parallel. Accordingly, the air discharged from the second cyclone unit (213b) may pass through the filter unit (214) and be divided into a plurality of cyclone bodies (213ba). Thereafter, the air discharged from the cyclone body (213ba) may flow upward and sequentially pass through the filter (270), the suction motor (216), and the air discharge cover (217).

[0116] As another example, the second cyclone section (213b) may also include a single cyclone body (213ba), and in this case, the axis of the cyclone flow of the second cyclone section (213b) may extend in the vertical direction.

[0117] The second cyclone section (213b) can be arranged at least partially inside the first cyclone section (213a) and can separate dust from the air discharged from the first cyclone section (213a).

[0118] The second cyclone section (213b) may be formed by a set of axial cyclones formed to separate dust from air flowing in the axial direction.

[0119] The second cyclone section (213b) may include a cyclone body (213ba), a vortex finder (213bb), a band member (213bc), and a guide vane (213bd).

[0120] The cyclone body (213ba) is configured to apply the principle of a dust collector that utilizes centrifugal force to separate dust from the air discharged from the first cyclone section (213a). A space through which air can flow can be formed inside the cyclone body (213ba), and air discharged from the first cyclone section (213a) can flow into the inside of the cyclone body (213ba).

[0121] The cyclone body (213ba) may be placed inside the filter unit (214). Specifically, at least a portion of the cyclone body (213ba) may be placed inside the filter body (214a), and air passing through the filter hole (214b) may be introduced into the inside of the cyclone body (213ba).

[0122] A plurality of cyclone bodies (213ba) may be provided. Each cyclone body (213ba) may be provided with an air inlet forming an outer wall surrounding the hollow portion. The outer walls surrounding the hollow portion formed by the cyclone bodies (213ba) may correspond to the outer walls of each axial cyclone. Air circulating along the inner surface of the cyclone body (213ba) may form a cyclonic flow.

[0123] Dust, which is heavier than air, can rotate within a vortex with a larger rotation radius than air. Since the dust rotates inside the cyclone body (213ba), the maximum rotation radius of the dust can be defined by the cyclone body (213ba).

[0124] The lower portion of the cyclone body (213ba) may have a slanted shape that becomes narrower as it goes down. The lower portion of the cyclone body (213ba) has a shape that becomes narrower as it goes down to induce the falling of dust separated from the air and prevent the dust from being discharged along the air to the vortex finder (213bb).

[0125] An air outlet may be formed at the bottom of the cyclone body (213ba). That is, dust separated from the air inside the cyclone body (213ba) can be discharged from the cyclone body (213ba) through the air outlet of the cyclone body (213ba). In addition, the bottom of the cyclone body (213ba) may be communicated with the internal space of the storage member (215, 1215). Therefore, dust rotating along the vortex inside the cyclone body (213ba) can fall and be stored in the storage member (215, 1215). The dust stored in the storage member (215, 1215) can be discharged to the flow path (180) through the dust passage hole (121a) when the dust collection motor (191) is driven.

[0126] The upper portion of the cyclone body (213ba) may be formed to accommodate a vortex finder (213bb). The upper portion of the cyclone body (213ba) may be formed to have a constant inner diameter. The upper and lower portions of the cyclone body (213ba) may be distinguished based on the position where the inner diameter narrows.

[0127] The outer surface of each cyclone body (213ba) is connected to be in contact with the surrounding cyclone bodies (213ba), so that a plurality of cyclone bodies (213ba) can form a single member. It is preferable that the cross-section of each cyclone body (213ba) has a circular shape as illustrated in the drawing. This is because when the cross-section of the cyclone body (213ba) is formed in a circular shape, even if the outer surfaces of adjacent cyclone bodies (213ba) are in close contact with each other, a flow path for air and dust can be formed between them. If a flow path for air and dust is formed between the cyclone bodies (213ba), there is an advantage in that a separate flow path structure does not need to be installed.

[0128] It is not excluded that the cross-section of each cyclone body (213ba) may be formed as a polygon. However, even if the cross-section of each cyclone body (213ba) is formed as a polygon, it is preferable that it be formed as a polygon in which a path for air and dust can be formed.

[0129] The vortex finder (213bb) and the band member (213bc) may be arranged above the cyclone body (213ba) to form a set of axial cyclones together with the cyclone body (213ba). The cyclone body (213ba) may form a part of the set, and the vortex finder (213bb) and the band member (213bc) may form the remaining part of the set. At this time, if the vortex finder (213bb) and the band member (213bc) are formed as one piece, a set of axial cyclones may be formed by a plurality of cyclone bodies (213ba) and one member.

[0130] The vortex finder (213bb) is configured to discharge air that has passed through the cyclone flow inside the cyclone body (213ba). A path through which air can flow may be formed inside the vortex finder (213bb). A plurality of vortex finders (213bb) may be provided, and each vortex finder (213bb) may be arranged inside each cyclone body (213ba). The outer surface of each vortex finder (213bb) may be spaced apart from the inner surface of each cyclone body (213ba). Each vortex finder (213bb) has an air inlet that forms an outer wall around the hollow portion, and air that has passed through the cyclone body (213ba) may be discharged through the air inlet of each vortex finder (213bb). Thereafter, the air passing through each vortex finder (213bb) can be discharged to the filter (270) through the air outlet of each vortex finder (213bb).

[0131] The lower portion of the vortex finder (213bb) may have a higher height than the band member (213bc). However, the upper portion of the vortex finder (213bb) may have the same height as the band member (213bc). The lower portion of the vortex finder (213bb) may protrude below the band member (213bc), but the upper portion may not.

[0132] It is preferable that the cross-section of each vortex finder (213bb) has a circular ring shape. This does not exclude the possibility that the cross-section of each vortex finder (213bb) may be formed into a polygon. However, even if the cross-section of each vortex finder (213bb) is formed into a polygon, it is preferable that it be formed into a polygon that can form a path for air and dust.

[0133] The band member (213bc) may be formed to surround the outer surface of the vortex finder (213bb). At this time, the band member (213bc) may be named by other names as needed. For example, names such as a ring portion, a ring portion, a border portion, a perimeter portion, a circle portion, a support portion, a connection portion, an outer portion, a cyclone boundary portion, an outer wall portion, etc. may be considered, and other names are also possible.

[0134] The band member (213bc) can be mounted on the filter body (214a) and can have a shape corresponding to the upper portion of the filter body (214a). The upper portion of the filter body (214a) can be formed in a circular shape, and the band member (213bc) can also be formed in a circular shape that surrounds the vortex finder (213bb). However, this does not exclude the possibility that the upper portion of the filter body (214a) and the band member (213bc) are formed in a polygonal shape.

[0135] The position fixing step (not shown) of the band member (213bc) can be fitted into the corresponding step (not shown) of the filter body (214a) to set the engagement position and prevent arbitrary relative rotation. Since arbitrary relative rotation may occur between the band member (213bc) and the filter body (214a), arbitrary relative rotation must be prevented for normal operation of the second cyclone unit (213b).

[0136] The vortex finder (213bb) and the band member (213bc) can be connected to each other to form a single integral member.

[0137] The guide vane (213bd) is configured to guide air discharged from the first cyclone section (213a) toward the inside of the cyclone body (213ba). The guide vane (213bd) can form a guide path through which air can flow toward the inside of the cyclone body (213ba). Accordingly, the air flowing along the guide path can form a swirling flow between the vortex finder (213bb) and the cyclone body (213ba).

[0138] At least a portion of the guide vane (213bd) may be positioned between the cyclone body (213ba) and the vortex finder (213bb) and may be connected to each cyclone body (213ba) and each vortex finder (213bb). One end of the guide vane (213bd) may be connected to the outer surface of the vortex finder (213bb) along a spiral direction, and the other end of the guide vane (213bd) may be connected to the inner surface of the cyclone body (213ba) along a spiral direction.

[0139] Each cyclone body (213ba) and each vortex finder (213bb) may be provided with a plurality of guide vanes (213bd), and the guide vanes (213bd) may extend in a spiral direction to generate a swirling flow. As the guide vanes (213bd) extend in a spiral direction, the guide path also extends in a spiral direction, and air and dust introduced into the air inlet of the cyclone body (213ba) may form a swirling flow.

[0140] The filter unit (214) can filter the air discharged from the cyclone unit (213). The filter unit (214) can guide the air separated from dust in the cyclone unit (213) to the second cyclone unit (213b). That is, the filter unit (214) can be a mesh filter having a plurality of holes.

[0141]

[0142] The filter unit (214) may include a filter body (214a) and a filter hole (214b).

[0143] The filter body (214a) may be placed inside the dustbin (220). Specifically, the filter body (214a) may be placed inside the cyclone unit (213). A second cyclone unit (213b) may be placed inside the filter body (214a). The filter body (214a) may be placed between the cyclone unit (213) and the second cyclone unit (213b). A cyclone flow may be formed along the outer periphery of the filter body (214a).

[0144] The filter body (214a) may be formed in a cylindrical shape, but is not limited thereto. The central axis of the filter body (214a) may extend in the vertical direction. The central axis of the filter body (214a) may extend along the longitudinal direction of the filter body (214a).

[0145] For example, the central axis of the filter body (214a) may be coaxial with the axis (a2) of the cyclone flow. As another example, the central axis of the filter body (214a) may be arranged parallel to the axis (a2) of the cyclone flow.

[0146] A storage member (215, 1215) may be placed on the lower side of the filter body (214a).

[0147] The filter hole (214b) can guide air into the interior of the filter body (214a). A plurality of filter holes (214b) can be formed in the longitudinal direction along the outer circumference of the filter body (214a).

[0148] The filter hole (214b) is a hole having a predetermined diameter, and large foreign substances contained in the air discharged from the cyclone section (213) can be filtered by the filter hole (214b). Accordingly, foreign substances such as hair are filtered by the filter hole (214b). The air passing through the filter hole (214b) can be introduced into the second cyclone section (213b) arranged inside the filter body (214a).

[0149] At this time, the outer side and / or outside of the filter body (214a) may mean the direction facing the cyclone section (213) based on the filter body (214a), and the inner side and / or inside of the filter body (214a) may mean the direction facing the second cyclone section (213b) based on the filter body (214a).

[0150] Meanwhile, the cyclone flow generated in the cyclone section (213) may include at least one bending point at which the direction of movement changes from flowing along the outside of the filter body (214a) to flowing into the inside of the filter body (214a) through the filter hole (214b).

[0151] For example, the cyclone flow flowing along the outside of the filter body (214a) can have its direction of travel changed to a direction in which it flows into the inside of the filter body (214a) by the suction force of the suction motor (216) at the inlet side of the filter hole (214b). As another example, the cyclone flow flowing along the outside of the filter body (214a) can have its direction of travel changed to a direction in which it flows into the inside of the filter body (214a) by the suction force of the dust collection motor (191) at the inlet side of the filter hole (214b).

[0152] At this time, the inlet side of the filter hole (214b) may mean a space where air flows into the filter hole (214b) from the cyclone unit (213). Specifically, the inlet side of the filter hole (214b) may mean a space that forms a boundary between the filter hole (214b) and the cyclone unit (213). In addition, the outlet side of the filter hole (214b) may mean a space where air is discharged from the filter hole (214b) to the second cyclone unit (213b). Specifically, the outlet side of the filter hole (214b) may mean a space that forms a boundary between the filter hole (214b) and the second cyclone unit (213b).

[0153] A storage member (215, 1215) for storing dust separated from the second cyclone unit (213b) may be placed inside the dust bin (220). The storage member (215, 1215) is coupled to the lower side of the second cyclone unit (213b) and may contact the upper surface of the discharge cover (222). The lower side of the storage member (215, 1215) may be open.

[0154]

[0155] The storage member (215, 1215) is configured to store dust separated from the first dust storage unit (215a, 1215a) and / or the second dust storage unit (215b, 1215b).

[0156] The storage member (215, 1215) can divide the space inside the dust bin (220) into a first dust storage unit (215a, 1215a) where dust separated from the first cyclone unit (213a) is stored, and a second dust storage unit (215b, 1215b) where dust separated from the second cyclone unit (213b) is stored. Accordingly, the space formed between the storage member (215, 1215) and the dust bin (220) can be defined as the first dust storage unit (215a, 1215a), and the lower internal space of the storage member (215, 1215) can be defined as the second dust storage unit (215b, 1215b).

[0157] The lower portion of the first dust storage unit (215a, 1215a) and the lower portion of the second dust storage unit (215b, 1215b) can be opened. In this case, the open lower portion of the second dust storage unit (215b, 1215b) may mean a dust discharge port (215ba, 1215ba).

[0158] The first dust storage unit (215a, 1215a) can be selectively opened and closed by the discharge cover (222). The first dust storage unit (215a, 1215a) can be exposed to the outside by the discharge cover (222).

[0159] When the dust collection motor (191) is driven while the discharge cover (222) and the door (141) are open, dust in the first dust storage unit (215a, 1215a) and the second dust storage unit (215b, 1215b) can pass through the dust passage hole (121a) and enter the flow path unit (180).

[0160]

[0161] The suction motor (216) can generate a suction force to suck in air. The suction motor (216) can be accommodated within the main body housing (211). The suction motor (216) can generate a suction force by rotation. For example, the suction motor (216) can be provided in a shape similar to a cylinder.

[0162] At this time, a cyclone flow in the cyclone section (213) can be generated by the suction force of the suction motor (216). Specifically, when the suction motor (216) is operated, the air sucked into the suction section (212) by the suction airflow generated by the suction motor (216) can generate a cyclone flow in the cyclone section (213).

[0163] Meanwhile, in this embodiment, a virtual suction motor axis (a4) extending the rotation axis of the suction motor (216) can be formed.

[0164]

[0165] An air exhaust cover (217) may be placed on one axial side of the main body housing (211). A filter for filtering air may be accommodated in the air exhaust cover (217). For example, a HEPA filter may be accommodated in the air exhaust cover (217).

[0166] An air discharge port (not shown) for discharging air sucked in by the suction force of the suction motor (216) may be formed in the air discharge cover (217).

[0167] A flow guide may be arranged in the air exhaust cover (217). The flow guide may guide the flow of air discharged through the air exhaust port (not shown).

[0168] The handle (218) can be held by the user. The handle (218) can be positioned at the rear of the suction motor (216). For example, the handle (218) can be formed in a shape similar to a cylinder. Alternatively, the handle (218) can be formed in a curved cylinder shape. The handle (218) can be positioned at a predetermined angle with respect to the main body housing (211), the suction motor (216), or the cyclone unit (213).

[0169] The handle (218) may include a grip portion formed in a column shape so that a user can grip it, a first extension portion connected to one longitudinal (axial) end of the grip portion and extending toward the suction motor (216), and a second extension portion connected to the other longitudinal (axial) end of the grip portion and extending toward the dust bin (220).

[0170] Meanwhile, in the present embodiment, a virtual gripping portion penetrating axis (a5) can be formed by extending along the longitudinal direction of the gripping portion (axial direction of the column) and penetrating the gripping portion.

[0171] For example, the grip portion penetration axis (a5) may be a virtual line formed inside a cylindrical handle (218), and may be a virtual line formed parallel to at least a portion of the outer surface (outer circumference) of the grip portion.

[0172] The upper surface of the handle (218) may form a portion of the outer appearance of the upper surface of the vacuum cleaner (200). This may prevent the components of the vacuum cleaner (200) from contacting the user's arm when the user holds the handle (218).

[0173] The first extension portion may extend from the grip portion toward the main body housing (211) or the suction motor (216). At least a portion of the first extension portion may extend in a horizontal direction.

[0174] The second extension may extend from the phasing portion toward the dust bin (220). At least a portion of the second extension may extend horizontally.

[0175] The operating unit (219) may be placed on the handle (218). The operating unit (219) may be placed on an inclined surface formed in the upper area of ​​the handle (218). The user may input an operation or stop command for the cleaner (200) through the operating unit (219).

[0176]

[0177] The vacuum cleaner (200) may include a dust bin (220). The dust bin (220) may store dust sucked in through the suction unit (212). The dust bin (220) may store dust separated from the cyclone unit (213).

[0178] The dustbin (220) may include a dustbin body (221), a discharge cover (222), a dustbin compression lever (223), and a compressor (not shown).

[0179] The dustbin body (221) can be communicated with the suction unit (212). Specifically, when the suction motor (216) is driven, the dustbin body (221) can be communicated with the suction unit (212).

[0180] The dustbin body (221) can provide a space for storing dust separated from the cyclone section (213). For example, the dustbin body (221) can be formed in a shape similar to a cylinder.

[0181] Meanwhile, in this specification, a virtual dustbin penetration line can be formed that penetrates the interior (internal space) of the dustbin body (221) and extends along the longitudinal direction of the dustbin body (221) (meaning the axial direction in the cylindrical dustbin body (221)). Specifically, in this specification, a dustbin central axis (a3) ​​can be defined that means the axial direction of the cylindrical dustbin body (221).

[0182] The dustbin central axis (a3) ​​may extend along the longitudinal direction of the dustbin (220). Specifically, the dustbin central axis (a3) ​​may extend along the longitudinal direction of the dustbin body (221). Therefore, the dustbin central axis (a3) ​​may refer to the longitudinal axis of the dustbin (220).

[0183] Additionally, in this specification, the axis of the cyclone flow (a2), the central axis of the dustbin (a3), and the suction motor axis (a4) may be aligned with or parallel to each other.

[0184] The lower surface (bottom surface) of the dustbin body (221) may be partially open. In addition, a lower extension (not shown) may be formed on the lower surface (bottom surface) of the dustbin body (221). The lower extension (not shown) may be formed to block a portion of the lower surface of the dustbin body (221).

[0185] The dustbin (220) may include a discharge cover (222). The discharge cover (222) may be placed on the lower surface of the dustbin (220).

[0186] The discharge cover (222) may be provided to open and close one longitudinal end of the dustbin body (221). The discharge cover (222) may selectively open and close the lower portion of the dustbin (220) that opens downward. The discharge cover (222) may selectively open and close the first dust storage portion (215a, 1215a) that opens downward.

[0187] The discharge cover (222) may include a cover body (222a) and a hinge portion (222b). The cover body (222a) may be formed to block a portion of the lower surface of the dustbin body (221). The cover body (222a) may rotate downward based on the hinge portion (222b). The hinge portion (222b) may be arranged adjacent to the battery housing (230). A torsion spring (not shown) may be provided in the hinge portion (222b). Therefore, when the discharge cover (222) is separated from the dustbin body (221), the cover body (222a) may be supported in a state in which it is rotated by a predetermined angle or more about the hinge portion (222b) as an axis by the elastic force of the torsion spring (not shown) in the dustbin body (221).

[0188] The discharge cover (222) can be coupled to the dust bin (220) through a hook connection. Meanwhile, the discharge cover (222) can be separated from the dust bin (220) through a coupling lever (222c). The coupling lever (222c) can be positioned at the front of the dust bin. Specifically, the coupling lever (222c) can be positioned on the outer surface of the front side of the dust bin (220). When an external force is applied, the coupling lever (222c) can elastically deform a hook extended from the cover body (222a) to release the hook connection between the cover body (222a) and the dust bin body (221).

[0189] When the discharge cover (222) is closed, the lower surface of the first dust storage unit (215a, 1215a) can be blocked (sealed) by the discharge cover (222) and the lower extension (not shown).

[0190] The dustbin (220) may include a dustbin compression lever (223) (see FIG. 4). The dustbin compression lever (223) may be positioned outside the dustbin (220) or the cyclone unit (213). The dustbin compression lever (223) may be positioned so as to move up and down outside the dustbin (220) or the cyclone unit (213). The dustbin compression lever (223) may be connected to a compressor (not shown). When the dustbin compression lever (223) moves downward by an external force, the compressor (not shown) may also move downward. This may provide convenience to the user. The compressor (not shown) and the dustbin compression lever (223) may return to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dustbin compression lever (223) is removed, the elastic member can move the dustbin compression lever (223) and the compressor (not shown) upward.

[0191] A compressor (not shown) may be placed inside the dustbin body (221). The compressor may move within the internal space of the dustbin body (221). Specifically, the compressor may move up and down within the dustbin body (221). Through this, the compressor may compress dust within the dustbin body (221) downward. In addition, when the discharge cover (222) is separated from the dustbin body (221) and the lower portion of the dustbin (220) is opened, the compressor may move from the upper portion to the lower portion of the dustbin (220) to remove foreign substances such as residual dust within the dustbin (220). Through this, the suction power of the vacuum cleaner may be improved by preventing residual dust from remaining within the dustbin (220). In addition, by preventing residual dust from remaining within the dustbin (220), an unpleasant odor caused by the residual dust may be eliminated.

[0192] The vacuum cleaner (200) may include a battery housing (230). The battery housing (230) may accommodate a battery (240). The battery housing (230) may be positioned below the handle (218). For example, the battery housing (230) may have a hexahedral shape with an open bottom. The rear of the battery housing (230) may be connected to the handle (218).

[0193] The battery housing (230) may include a receiving portion that opens downward. The battery (240) may be removed through the receiving portion of the battery housing (230).

[0194] The vacuum cleaner (200) may include a battery (240).

[0195] For example, the battery (240) may be detachably coupled to the vacuum cleaner (200). The battery (240) may be detachably coupled to the battery housing (230). For example, the battery (240) may be inserted into the interior of the battery housing (230) from the bottom of the battery housing (230). With such a configuration, the portability of the vacuum cleaner (200) may be improved.

[0196] In contrast, the battery (240) may be integrally provided inside the battery housing (230). In this case, the lower surface of the battery (240) is not exposed to the outside.

[0197] The battery (240) can supply power to the suction motor (216) of the vacuum cleaner (200). The battery (240) can be placed at the bottom of the handle (218). The battery (240) can be placed at the rear of the dust bin (220).

[0198] In an embodiment, when the battery (240) is coupled to the battery housing (230), the lower surface of the battery (240) may be exposed to the outside. When the vacuum cleaner (200) is placed on the floor, the battery (240) may be placed on the floor, so that the battery (240) can be immediately separated from the battery housing (230). In addition, since the lower surface of the battery (240) is exposed to the outside and comes into direct contact with the external air of the battery (240), the cooling performance of the battery (240) may be improved.

[0199] Meanwhile, when the battery (240) is integrally fixed to the battery housing (230), the structure for attaching and detaching the battery (240) and the battery housing (230) can be reduced, so that the overall size of the vacuum cleaner (200) can be reduced and its weight can be reduced.

[0200] The vacuum cleaner (200) may include an extension pipe (250). The extension pipe (250) may be connected to a cleaning module (260). The extension pipe (250) may be connected to a main body (210). The extension pipe (250) may be connected to a suction unit (212) of the main body (210). The extension pipe (250) may be formed in a long cylindrical shape.

[0201] The main body (210) can be connected to an extension pipe (250). The main body (210) can be connected to a cleaning module (260) through the extension pipe (250). The main body (210) can generate suction force through a suction motor (216) and provide suction force to the cleaning module (260) through the extension pipe (250). External dust can be introduced into the main body (210) through the cleaning module (260) and the extension pipe (250).

[0202] The vacuum cleaner (200) may include a cleaning module (260). The cleaning module (260) may be connected to an extension pipe (250). Accordingly, external air may be drawn into the main body (210) of the vacuum cleaner (200) through the cleaning module (260) and the extension pipe (250) by the suction force generated in the main body (210) of the vacuum cleaner (200).

[0203] Dust inside the dust bin (220) of the vacuum cleaner (200) can be collected by the dust collection unit (170) of the vacuum cleaner station (100) by gravity and the suction power of the dust collection motor (191). This allows the dust inside the dust bin to be removed without any separate operation by the user, thereby providing user convenience. In addition, the inconvenience of having to empty the dust bin every time can be eliminated. In addition, when the dust bin is emptied, dust can be prevented from flying.

[0204] The vacuum cleaner (200) can be coupled to the side of the housing (110). Specifically, the main body (210) of the vacuum cleaner (200) can be mounted on the coupling portion (120). More specifically, the dustbin (220) and the battery housing (230) of the vacuum cleaner (200) can be coupled to the coupling surface (121), the outer circumference of the dustbin main body (221) can be coupled to the dustbin guide surface (122), and the suction portion (212) can be coupled to the suction portion guide surface (126) of the coupling portion (120). In this case, the central axis (a3) ​​of the dustbin can be arranged in a direction parallel to the ground, and the extension pipe (250) can be arranged along a direction perpendicular to the ground.

[0205]

[0206] The vacuum cleaner (200) may include a filter (270). The filter (270) may separate dust from air passing through the second cyclone unit (213b). The filter (270) may be placed inside the main body housing (211). The filter (270) may be configured in a shape similar to a cylinder. When the filter (270) is placed inside the main body housing (211), the filter (270) may partition the inside of the main body housing (211) into an inner space (270a) of the filter and an outer space (270b).

[0207] The filter (270) may be placed on the upper side of the second cyclone unit (213b), and the filter (270) may be placed on the lower side of the suction motor (216). The filter (270) may be placed between the second cyclone unit (213b) and the suction motor (216).

[0208] Meanwhile, in this specification, the upper side may mean the direction in which the suction motor (216) is arranged based on the second cyclone section (213b), and the lower side may mean the direction in which the second dust storage section (215b, 1215b) is arranged based on the second cyclone section (213b).

[0209] When the suction motor (216) is driven, air that has passed through the second cyclone unit (213b) can flow from the outside to the inside of the filter (270). Specifically, when the suction motor (216) is driven, air that has passed through the second cyclone unit (213b) can be introduced into the external space (270b) of the filter. Thereafter, air introduced into the external space (270b) of the filter can pass through the filter (270) and be introduced into the internal space (270a) of the filter. Thereafter, air introduced into the internal space (270a) of the filter can be introduced into the suction motor (216). Thereafter, air introduced into the suction motor (216) can be discharged to the outside through the air discharge port of the air discharge cover (217).

[0210]

[0211] Referring to FIGS. 1 and 2, the cleaning station (100) of the present invention is described as follows.

[0212] A cleaner (200) may be placed in the cleaner station (100). The cleaner (200) may be coupled to a side of the cleaner station (100). Specifically, the main body of the cleaner (200) may be coupled to the side of the cleaner station (100). The cleaner station (100) may remove dust from the dust bin (220) of the cleaner (200).

[0213] The cleaning station (100) may include a housing (110). The housing (110) may form the exterior of the cleaning station (100). Specifically, the housing (110) may be formed in a columnar shape including at least one outer wall surface. For example, the housing (110) may be formed in a shape similar to a square column.

[0214] The housing (110) may be formed with a space that can accommodate a dust collection unit (170) that stores dust inside and a dust suction module (190) that generates a fluid force that collects dust by the dust collection unit (170).

[0215] The housing (110) may include a bottom surface (111), an outer wall surface (112), and an upper surface (113).

[0216] The bottom surface (111) can support the lower side of the dust suction module (190) in the direction of gravity. That is, the bottom surface (111) can support the lower side of the dust collection motor (171) of the dust suction module (190).

[0217] At this time, the bottom surface (111) can be positioned facing the ground. The bottom surface (111) can be positioned parallel to the ground, but can also be positioned at a predetermined angle with the ground. This configuration can stably support the dust collection motor (171), and has the advantage of balancing the overall weight even when the vacuum cleaner (200) is combined.

[0218] Meanwhile, according to an embodiment, the floor surface (111) may further include a ground support portion (111a) that increases the area in contact with the ground to prevent the cleaner station (100) from falling over and maintain balance. For example, the ground support portion may be in the form of a plate extending from the floor surface (111), and one or more frames may be formed to protrude and extend along the ground direction from the floor surface (111).

[0219] The outer wall surface (112) may refer to a surface formed along the direction of gravity and may refer to a surface connected to the floor surface (111). For example, the outer wall surface (112) may refer to a surface connected perpendicularly to the floor surface (111). In another embodiment, the outer wall surface (112) may be arranged to be inclined at a predetermined angle with respect to the floor surface (111).

[0220] The outer wall surface (112) may be configured to include at least one surface. For example, the outer wall surface (112) may include a first outer wall surface (112a), a second outer wall surface (not shown), a third outer wall surface (112c), and a fourth outer wall surface (not shown).

[0221] At this time, in the present embodiment, the first outer wall surface (112a) may be placed on the front side of the cleaner station (100). Here, the front side may refer to the surface where the cleaner (200) is exposed when the cleaner (200) is coupled to the cleaner station (100). Therefore, the first outer wall surface (112a) may form the appearance of the front side of the cleaner station (100).

[0222] Meanwhile, for the purpose of understanding this embodiment, the direction is defined as follows. In this embodiment, the direction can be defined while the cleaner (200) is mounted on the cleaner station (100).

[0223] When the cleaner (200) is mounted on the cleaner station (100), the direction in which the cleaner (200) is exposed to the outside of the cleaner station (100) can be called the front.

[0224] From another perspective, when the cleaner (200) is mounted on the cleaner station (100), the direction in which the suction motor (216) of the cleaner (200) is positioned can be called the front. And the direction opposite to the direction in which the suction motor (216) is positioned in the cleaner station (100) can be called the rear.

[0225] And, based on the internal space of the housing (110), the surface facing the front can be called the rear of the cleaner station (100). Accordingly, the rear can mean the direction in which the second outer wall surface (not shown) is formed.

[0226] And, when looking at the front surface based on the internal space of the housing (110), the left side may be called the left side, and the right side may be called the right side. Accordingly, the left side may refer to the direction in which the third outer wall surface (112c) is formed, and the right side may refer to the direction in which the fourth outer wall surface (not shown) is formed.

[0227] The first outer wall surface (112a) may be formed in a flat shape, or may be formed in a curved shape overall, or may be formed to include a curved surface in a portion.

[0228] The first outer wall surface (112a) may have an exterior shape corresponding to the shape of the cleaner (200). Specifically, a coupling portion (120) may be arranged on the first outer wall surface (112a). With this configuration, the cleaner (200) may be coupled to the cleaner station (100) and supported by the cleaner station (100). The specific configuration of the coupling portion (120) will be described later.

[0229] Meanwhile, it is also possible to add a structure to the first outer wall surface (112a) to accommodate various types of cleaning modules (260) used in the vacuum cleaner (200).

[0230] In this embodiment, the second outer wall surface (not shown) may be a surface facing the first outer wall surface (112a). That is, the second outer wall surface (not shown) may be arranged on the rear side of the cleaner station (100). Here, the rear side may be a surface facing the surface to which the cleaner (200) is coupled. Accordingly, the second outer wall surface (not shown) may form the exterior appearance of the rear side of the cleaner station (100).

[0231] For example, the second outer wall surface (not shown) may be formed in a flat shape. With this configuration, the cleaner station (100) can be attached to an indoor wall and stably supported.

[0232] As another example, a structure for mounting various types of cleaning modules (260) used in a vacuum cleaner (200) may be added to the second outer wall surface (not shown).

[0233] In this embodiment, the third outer wall surface (112c) and the fourth outer wall surface (not shown) may refer to surfaces connecting the first outer wall surface (112a) and the second outer wall surface (not shown). At this time, the third outer wall surface (112c) may be arranged on the left side of the station (100), and the fourth outer wall surface (not shown) may be arranged on the right side of the cleaner station (100). Alternatively, the third outer wall surface (112c) may be arranged on the right side of the cleaner station (100), and the fourth outer wall surface (not shown) may be arranged on the left side of the cleaner station (100).

[0234] The third outer wall surface (112c) or the fourth outer wall surface (not shown) may be formed in a flat shape, or may be formed in a curved shape overall, or may be formed by including a curved surface in a portion thereof.

[0235] Meanwhile, it is also possible to add a structure for mounting various types of cleaning modules (260) used in a vacuum cleaner (200) to the third outer wall surface (112c) or the fourth outer wall surface (not shown).

[0236] The upper surface (113) may form the upper exterior of the cleaner station. That is, the upper surface (113) may mean a surface that is positioned at the uppermost side in the direction of gravity in the cleaner station and is exposed to the outside.

[0237] For reference, in this embodiment, the upper and lower sides may mean the upper and lower sides, respectively, along the direction of gravity (the direction perpendicular to the ground) when the cleaner station (100) is installed on the ground.

[0238] At this time, the upper surface (113) may be arranged parallel to the ground, or may be arranged at a certain angle with the ground.

[0239] A display unit (410) may be arranged on the upper surface (113). For example, the display unit (410) may display the status of the cleaner station (100) and the status of the cleaner (200), and may also display information such as the cleaning progress status and a map of the cleaning area.

[0240] Meanwhile, depending on the embodiment, the upper surface (113) may be provided to be detachable from the outer wall surface (112). In this case, when the upper surface (113) is detached, the internal space surrounded by the outer wall surface (112) may accommodate a battery detached from the vacuum cleaner (200), and a terminal (not shown) for charging the detached battery may be provided.

[0241]

[0242] FIG. 6 is a drawing for explaining the relationship between a cleaner and a door unit in a cleaner station according to an embodiment of the present invention, and FIG. 7 is a drawing for explaining the relationship between a cleaner and a cover opening unit in a cleaner station according to an embodiment of the present invention.

[0243] The coupling part (120) of the cleaner station (100) of the present invention is described as follows.

[0244] The vacuum cleaner station (100) may include a coupling part (120) to which the vacuum cleaner (200) is coupled. Specifically, the coupling part (120) is arranged on the first outer wall surface (112a), and the main body (210), dust bin (220), and battery housing (230) of the vacuum cleaner (200) may be coupled.

[0245] The coupling portion (120) may include a coupling surface (121). The coupling surface (121) may be arranged on a side surface of the housing (110). For example, the coupling surface (121) may refer to a surface formed in a concave groove shape toward the inside of the cleaner station (100) on the first outer wall surface (112a). In other words, the coupling surface (121) may refer to a surface formed by forming a single unit with the first outer wall surface (112a).

[0246] A vacuum cleaner (200) may be coupled to the coupling surface (121). For example, the coupling surface (121) may be in contact with the lower surface of the dust bin (220) and the battery housing (230) of the vacuum cleaner (200). Here, the lower surface may refer to the surface facing the ground when the user uses the vacuum cleaner (200) or places it on the ground.

[0247] For example, the angle formed by the coupling surface (121) with the ground may be a right angle. This allows the space of the cleaning station (100) to be minimized when the cleaner (200) is coupled to the coupling surface (121).

[0248] As another example, the coupling surface (121) may be arranged to be inclined at a predetermined angle with respect to the ground. Through this, when the cleaner (200) is coupled to the coupling surface (121), the cleaner station (100) can be stably supported.

[0249] A dust passage hole (121a) may be formed in the coupling surface (121) to allow air from outside the housing (110) to flow into the inside. The dust passage hole (121a) may be formed in a hole shape corresponding to the shape of the dust bin (220) so that dust from the dust bin (220) may flow into the dust collection unit (170). The dust passage hole (121a) may be formed corresponding to the shape of the discharge cover (222) of the dust bin (220). The dust passage hole (121a) may be formed to communicate with the first suction passage (181) to be described later.

[0250] The coupling portion (120) may include a dustbin guide surface (122). The dustbin guide surface (122) may be arranged on the first outer wall surface (112a). The dustbin guide surface (122) may be connected to the first outer wall surface (112a). In addition, the dustbin guide surface (122) may be connected to the coupling surface (121).

[0251] The dustbin guide surface (122) may be formed in a shape corresponding to the outer surface of the dustbin (220). The front outer surface of the dustbin (220) may be coupled to the dustbin guide surface (122). This provides convenience in coupling the vacuum cleaner (200) to the coupling surface (121).

[0252] Meanwhile, a protrusion movement hole (122a) may be formed in the dustbin guide surface (122), and a push protrusion (151), which will be described later, may be linearly moved along the protrusion movement hole (122a). In addition, a gear box (155), which accommodates a gear of a cover opening unit (150), which will be described later, may be provided on the lower side of the dustbin guide surface (122) in the gravity direction. At this time, a guide space (122b), in which the push protrusion (151) can move, may be formed between the dustbin guide surface (122), the lower side, and the upper side of the gear box (155). In addition, the guide space (122b) may be communicated with the first suction passage (181) through a bypass hole (122c). That is, the protrusion movement hole (122a), the guide space (122b), the bypass hole (122c), and the first suction path (181) can form a single bypass path (see Fig. 14). With this configuration, when the dust collector motor (191) is operated while the dust bin (220) is connected to the connecting portion (120), there is an advantage in that dust remaining in the dust bin (220) and the dust bin guide surface (122) can be sucked in through the bypass path.

[0253] The coupling portion (120) may include a guide protrusion (123). The guide protrusion (123) may be positioned on the coupling surface (121). The guide protrusion (123) may protrude upward from the coupling surface (121). Two guide protrusions (123) may be positioned spaced apart from each other. The distance between the two guide protrusions (123) spaced apart from each other may correspond to the width of the battery housing (230) of the cleaner (200). Through this, the convenience of coupling the cleaner (200) to the coupling surface (121) may be provided.

[0254] The coupling portion (120) may include a side wall (124). The side wall (124) may refer to a wall surface disposed on both sides of the coupling surface (121) and may be vertically connected to the coupling surface (121). The side wall (124) may be connected to the first outer wall surface (112a). In addition, the side wall (124) may form a surface connected to the dustbin guide surface (122). Through this, the vacuum cleaner (200) may be stably accommodated.

[0255] The coupling unit (120) may include a coupling sensor (125). The coupling sensor (125) may detect whether the cleaner (200) is coupled to the coupling unit (120).

[0256] The coupling sensor (125) may also include a contact sensor. For example, the coupling sensor (125) may include a micro switch. In this case, the coupling sensor (125) may be placed on the guide protrusion (123). Accordingly, when the battery housing (230) or the battery (240) of the cleaner (200) is coupled between a pair of guide protrusions (123), the coupling sensor (125) comes into contact with the cleaner, and the coupling sensor (125) can detect that the cleaner (200) has been coupled.

[0257] Meanwhile, the coupling sensor (125) may also include a non-contact sensor. For example, the coupling sensor (125) may include an infrared sensor (IR sensor). In this case, the coupling sensor (125) may be placed on the side wall (124). Accordingly, when the dust bin (220) or the main body (210) of the cleaner (200) passes the side wall (124) and reaches the coupling surface (121), the coupling sensor (125) may detect the presence of the dust bin (220) or the main body (210).

[0258] The coupling sensor (125) may face the dust bin (220) or battery housing (230) of the vacuum cleaner (200).

[0259] The coupling sensor (125) can be a means for determining whether the vacuum cleaner (200) is coupled with power being supplied to the battery (240) of the vacuum cleaner (200).

[0260] The coupling portion (120) may include a suction portion guide surface (126). The suction portion guide surface (126) may be arranged on the first outer wall surface (112a). The suction portion guide surface (126) may be connected to the dustbin guide surface (122). A suction portion (212) may be coupled to the suction portion guide surface (126). The shape of the suction portion guide surface (126) may be formed to correspond to the shape of the suction portion (212).

[0261] The connecting portion (120) may further include a fixed member entry / exit hole (127). The fixed member entry / exit hole (127) may be formed in the shape of a long hole along the side wall (124) so ​​that the fixed member (131) can enter / exit.

[0262] With this configuration, when a user couples the cleaner (200) to the coupling portion (120) of the cleaner station (100), the main body (210) of the cleaner (200) can be stably placed on the coupling portion (120) by the dustbin guide surface (122), the guide protrusion (123), and the suction portion guide surface (126). Through this, the convenience of coupling the dustbin (220) and the battery housing (230) of the cleaner (200) to the coupling portion (121) can be provided.

[0263]

[0264] The fixed unit (130) according to the present invention is described as follows.

[0265] The cleaner station (100) of the present invention may include a fixing unit (130). The fixing unit (130) may be disposed on a side wall (124). In addition, at least a portion of the fixing unit (130) may be disposed on the back surface of the coupling surface (121). The fixing unit (130) may fix a cleaner (200) coupled to the coupling surface (121). Specifically, the fixing unit (130) may fix a dust bin (220) and a battery housing (230) of the cleaner (200) coupled to the coupling surface (121).

[0266] The fixed unit (130) may include a fixed member (131) that fixes the dust bin (220) and battery housing (230) of the vacuum cleaner (200), and a fixed motor (133) that drives the fixed member (131). In addition, the fixed unit (130) may further include a fixed link (not shown) that transmits the power of the fixed motor (133) to the fixed member (131).

[0267] The fixing member (131) is arranged on the side wall (124) of the joint (120) and may be provided to be reciprocally movable on the side wall (124) to fix the dustbin (220). Specifically, the fixing member (131) may be accommodated inside the fixing member access hole (127).

[0268] The fixing members (131) can be arranged on each side of the joint (120). For example, two fixing members (131) can be arranged symmetrically in pairs around the joint surface (121).

[0269] The fixed motor (133) can provide power to move the fixed member (131).

[0270] The fixed link (not shown) can convert the rotational force of the fixed motor (133) into reciprocating movement of the fixed member (131).

[0271] The fixed sealer (136) can be placed on the dustbin guide surface (122) to seal the dustbin (220) when the vacuum cleaner (200) is coupled. With this configuration, when the dustbin (220) of the vacuum cleaner (200) is coupled, the fixed sealer (136) can be pressurized by the weight of the vacuum cleaner (200), and the dustbin (220) and the dustbin guide surface (122) can be sealed.

[0272] The fixed sealer (136) can be placed on a virtual extension of the fixed member (131). With this configuration, when the fixed member motor (133) is operated and the fixed member (131) pressurizes the dust bin (220), the circumference of the dust bin (220) at the same height can be sealed.

[0273] According to an embodiment, the fixed sealer (136) may be placed on the dustbin guide surface (122) in a bent line shape corresponding to the arrangement of the cover opening unit (150) described later.

[0274] Accordingly, when the main body (210) of the cleaner (200) is placed on the coupling portion (120), the fixing unit (130) can fix the main body (210) of the cleaner (200). Specifically, when the coupling sensor (125) detects that the main body (210) of the cleaner (200) is coupled to the coupling portion (120) of the cleaner station (100), the fixing portion motor (133) can move the fixing member (131) to fix the main body (210) of the cleaner (200).

[0275] This improves the vacuum's suction power by preventing residual dust from remaining in the bin. Furthermore, by preventing residual dust from remaining in the bin, it eliminates any unpleasant odors caused by residual dust.

[0276]

[0277] The door unit (140) of the present invention will be described with reference to FIGS. 2, 6, and 8 as follows.

[0278] The vacuum cleaner station (100) of the present invention may include a door unit (140). The door unit (140) may be configured to open and close a dust passage hole (121a).

[0279] The door unit (140) may include a door (141), a door motor (142), and a door arm (143).

[0280] The door (141) is hingedly connected to the joining surface (121) and can open and close the dust passage hole (121a). The door (141) may include a door body (141a).

[0281] The door body (141a) may be formed in a shape that can block the dust passage hole (121a). For example, the door body (141a) may be formed in a shape similar to a circular plate.

[0282] Based on the state in which the door body (141a) blocks the dust passage hole (121a), a hinge part may be arranged on the upper side of the door body (141a), and a female coupling part (141b) may be arranged on the lower side of the door body (141a).

[0283] The door body (141a) may be formed in a shape that can seal the dust passage hole (121a). For example, the outer surface of the door body (141a) exposed to the outside of the cleaner station (100) is formed to have a diameter corresponding to the diameter of the dust passage hole (121a), and the inner surface disposed inside the cleaner station (100) is formed to have a diameter larger than the diameter of the dust passage hole (121a). In addition, a step may be generated between the outer surface and the inner surface. Meanwhile, at least one reinforcing rib may be formed to protrude on the inner surface of the door body (141a) to connect the hinge portion and the arm joint portion (141b) and to strengthen the supporting force of the door body (141a).

[0284] The hinge portion may be a means for hinge-connecting the door (141) to the joining surface (121). The hinge portion may be arranged at the upper end of the door body (141a) and may be connected to the joining surface (121).

[0285] The arm coupling portion (141b) may be a means to which the door arm (143) is rotatably coupled. The arm coupling portion (141b) is positioned on the lower side of the door body (141a), is rotatably coupled with the door body (141a), and the door arm (143) may be rotatably coupled thereto.

[0286] With this configuration, when the door arm (143) pulls the door body (141a) while the door (141) is closing the dust passage hole (121a), the door body (141a) rotates toward the inside of the cleaner station (100) with the hinge portion as an axis, and the dust passage hole (121a) can be opened. On the other hand, when the door arm (143) pushes the door body (141a) while the dust passage hole (121a) is open, the door body (141a) rotates toward the outside of the cleaner station (100) with the hinge portion (141b) as an axis, and the dust passage hole (121a) can be blocked.

[0287] Meanwhile, when the vacuum cleaner (200) is coupled to the vacuum cleaner station (100) and the discharge cover (222) is separated from the dustbin body (210), the door (141) can come into contact with the discharge cover (222). In addition, the discharge cover (222) can rotate in conjunction with the door (141) according to the rotation of the door (141).

[0288] The door motor (142) can provide power to rotate the door (141). Specifically, the door motor (142) can rotate the door arm (143) in a forward or reverse direction. Here, the forward direction may refer to a direction in which the door arm (143) pulls the door (141). Accordingly, when the door arm (143) rotates in a forward direction, the dust passage hole (121a) can be opened. In addition, the reverse direction may refer to a direction in which the door arm (143) pushes the door (141). Accordingly, when the door arm (143) rotates in a reverse direction, the dust passage hole (121a) can be at least partially closed. The forward direction may be the opposite direction to the reverse direction.

[0289] The door arm (143) connects the door (141) and the door motor (142), and can open and close the door (141) using the power generated from the door motor (142).

[0290] For example, the door arm (143) may include a first door arm (143a) and a second door arm (143b). One end of the first door arm (143a) may be coupled to a door motor (142). The first door arm (143a) may be rotated by the power of the door motor (142). The other end of the first door arm (143a) may be rotatably coupled to a second door arm (143b). The first door arm (143a) may transmit force transmitted from the door motor (142) to the second door arm (143b). One end of the second door arm (143b) may be coupled to the first door arm (143a). The other end of the second door arm (143b) may be coupled to the door (141). The second door arm (143b) can open or close the dust passage hole (121a) by pushing or pulling the door (141).

[0291] The door unit (140) may further include a door open / close detection unit (144). The door open / close detection unit (144) may be provided inside the housing (110) and may detect whether the door (141) is in an open state.

[0292] For example, the door open / close detection unit (144) may be positioned at each end of the rotational movement area of ​​the door arm (143). As another example, the door open / close detection unit (144) may be positioned at each end of the movement area of ​​the door (141).

[0293] Accordingly, when the door arm (143) moves to a preset door opening position or the door (141) opens to a predetermined position, the door open / close detection unit (144) can detect that the door is opened. In addition, when the door arm (143) moves to a preset door closing position or the door (141) opens to a predetermined position, the door open / close detection unit (144) can detect that the door is opened.

[0294] The door open / close detection unit (144) may include a contact sensor. For example, the door open / close detection unit (144) may include a micro switch.

[0295] Meanwhile, the door opening / closing detection unit (144) may also include a non-contact sensor. For example, the door opening / closing detection unit (144) may include an infrared sensor (IR sensor).

[0296] With this configuration, the door unit (140) can selectively open and close at least a portion of the joining surface (121) to connect the outer side of the first outer wall surface (112a) with the flow path (180) and / or the dust collection unit (170).

[0297] The door unit (140) can be opened together with the discharge cover (222) of the cleaner (200). In addition, when the door unit (140) is closed, the discharge cover (222) of the cleaner (200) can be closed together with it.

[0298] When dust in the dust bin (220) of the vacuum cleaner (200) is removed, the door motor (142) can rotate the door (141) to connect the discharge cover (222) to the dust bin body (221). Specifically, the door motor (142) rotates the door (141), and the rotating door (141) can push the discharge cover (222) toward the dust bin body (221).

[0299]

[0300] The cover opening unit (150) of the present invention will be described with reference to FIGS. 2, 7, and 8 as follows.

[0301] The cleaner station (100) of the present invention may include a cover opening unit (150). The cover opening unit (150) is disposed at the coupling portion (120) and may open the discharge cover (222) of the cleaner (200).

[0302] The cover opening unit (150) may include a push projection (151), a cover opening motor (152), a cover opening gear (153), a support plate (154), and a gear box (155).

[0303] The push lug (151) can be moved to pressurize the coupling lever (222c) when the vacuum cleaner (200) is coupled.

[0304] The push protrusion (151) can be placed on the dustbin guide surface (122). Specifically, a protrusion movement hole can be formed on the dustbin guide surface (122), and the push protrusion (151) can pass through the protrusion movement hole and be exposed to the outside.

[0305] The push projection (151) may be positioned at a position where the coupling lever (222c) can be pressed when the vacuum cleaner (200) is coupled. That is, the coupling lever (222c) may be positioned on the projection movement hole. In addition, the coupling lever (222c) may be positioned on the movement area of ​​the push projection (151).

[0306] The push projection (151) can move linearly back and forth to pressurize the coupling lever (222c). Specifically, the push projection (151) can be coupled to a gear box (155) to guide linear movement. The push projection (151) can be coupled to a cover opening gear (153) to move together with the movement of the cover opening gear (153).

[0307] The cover opening motor (152) can provide power to move the push protrusion (151). Specifically, the cover opening motor (152) can rotate the motor shaft (not shown) in a forward or reverse direction. Here, the forward direction may refer to the direction in which the push protrusion (151) presses the coupling lever (222c). In addition, the reverse direction may refer to the direction in which the push protrusion (151) that presses the coupling lever (222c) returns to its original position. The forward direction may be the opposite direction to the reverse direction.

[0308] The cover opening gear (153) is coupled with the cover opening motor (152) and can move the push projection (151) using the power of the cover opening motor (152). Specifically, the cover opening gear (153) can be accommodated inside the gear box (155). The driving gear (153a) of the cover opening gear (153) can be coupled with the motor shaft of the cover opening motor (152) to receive power. The driven gear (153b) of the cover opening gear (153) can be coupled with the push projection (151) to move the push projection (151). For example, the driven gear (153b) is provided in the form of a rack gear and meshes with the driving gear (153a) and can receive power from the driving gear (153a).

[0309] At this time, the discharge cover (222) may be equipped with a torsion spring (not shown). By the elastic force of the torsion spring (not shown), the discharge cover (222) can be rotated by a predetermined angle or more and supported in the rotated position. Accordingly, the discharge cover (222) can be opened, and the dust passage hole (121a) and the inside of the dust bin (220) can be connected.

[0310] The gear box (155) is provided inside the housing (110) and is placed on the lower side in the direction of gravity of the coupling part (120), and the cover opening gear (153) can be accommodated inside.

[0311] The gear box (155) may be equipped with a cover opening detection unit (155f). At this time, the cover opening detection unit (155f) may include a contact sensor. For example, the cover opening detection unit (155f) may include a micro switch. Meanwhile, the cover opening detection unit (155f) may also include a non-contact sensor. For example, the cover opening detection unit (155f) may include an infrared sensor (IR sensor).

[0312] At least one cover opening detection unit (155f) may be arranged on the inner or outer surface of the gear box (155). For example, one cover opening detection unit (155f) may be arranged on the inner surface of the gear box (155). At this time, the cover opening detection unit (155f) may detect that the push projection (151) is in the initial position.

[0313] As another example, two cover opening detection units (155f) may be arranged on the outer surface of the gear box (155). At this time, the cover opening detection units (155f) can detect the initial position of the push protrusion (151) and the cover opening position.

[0314] Therefore, according to the present invention, the user can open the dust bin (220) without having to separately open the discharge cover (222) of the vacuum cleaner by means of the cover opening unit (150), thereby improving convenience.

[0315] In addition, since the discharge cover (222) is opened while the vacuum cleaner (200) is connected to the vacuum cleaner station (100), there is an effect of preventing dust from flying.

[0316]

[0317] Meanwhile, the dust collection unit (170) will be described as follows with reference to FIG. 2 and FIG. 8.

[0318] The vacuum cleaner station (100) may include a dust collection unit (170). The dust collection unit (170) may be placed inside the housing (110). The dust collection unit (170) may be placed below the gravity direction of the coupling unit (120).

[0319] For example, the dust collection unit (170) may mean a dust bag that collects dust sucked from inside the dust bin (220) of the vacuum cleaner (200) by the dust collection motor (191).

[0320] The dust collection unit (170) can be detachably coupled to the housing (110).

[0321] Accordingly, the dust collector (170) can be separated from the housing (110) and discarded, and a new dust collector (170) can be combined with the housing (110). That is, the dust collector (170) can be defined as a consumable part.

[0322] The dust bag may be provided so that when suction power is generated by the dust collection motor (191), its volume increases and dust is accommodated inside.

[0323] To achieve this, the dust bag may be made of a material that is permeable to air but impermeable to foreign substances such as dust. For example, the dust bag may be made of a non-woven material and may have a hexahedral shape when expanded.

[0324] Therefore, user convenience can be improved as there is no need for the user to separately bundle dust-collecting bags, etc.

[0325] Alternatively, the dust bag may be formed of a permeable material. For example, the dust bag may include a roll of vinyl (not shown). With this configuration, when the dust bag is sealed or bonded, dust or odors trapped within the dust bag can be prevented from leaking out of the dust bag. At this time, the dust bag may be mounted to the housing (110) via a dust bag cartridge (not shown). If necessary, the dust bag may be replaced via the dust bag cartridge.

[0326]

[0327] Meanwhile, referring to FIG. 2 and FIG. 6, the euro section (180) is described as follows.

[0328] The cleaner station (100) may include a euro section (180).

[0329] The flow path (180) can connect the dust bin (220) and the dust collection unit (170) of the vacuum cleaner (200). The flow path (180) can be arranged on the rear side of the coupling surface (121). The flow path (180) can refer to a space between the dust bin (220) and the dust collection unit (170) of the vacuum cleaner (200). The flow path (180) can be a space formed rearward from the dust passage hole (121a), and can be a flow path formed by bending downward from the dust passage hole (121a) so that dust and air can flow.

[0330] Specifically, when the cleaner (200) is coupled to the cleaner station (100) and the dust passage hole (121a) is opened, it may include a first suction passage (181) that communicates with the internal space of the dust bin (220), and a second suction passage (182) that communicates between the first suction passage (181) and the internal space of the dust collection unit (170).

[0331] For example, the first suction passage (181) may be arranged substantially parallel to the suction motor axis (a4) or the dustbin central axis (a3) ​​penetrating the dustbin (220). At this time, the suction motor axis (a4) or the dustbin central axis (a3) ​​may pass through the first suction passage (181).

[0332] At this time, the second suction path (182) may be formed at a predetermined angle with the first suction path (181). For example, the first suction path (181) and the second suction path (182) may be formed at a right angle. With this configuration, the overall volume of the cleaner station (100) can be minimized.

[0333] Dust in the dust bin (220) of the vacuum cleaner (200) can move to the dust collection unit (170) through the euro section (180).

[0334]

[0335] Meanwhile, the dust suction module (190) will be described with reference to FIG. 2 and FIG. 8 as follows.

[0336] The vacuum cleaner station (100) may include a dust suction module (190). The dust suction module (190) may generate a suction airflow so that dust inside the dust bin (220) is sucked into the dust collection unit (170) through the duct (180).

[0337] The dust suction module (190) may include a dust collection motor (191), a first filter (192), and a second filter (not shown).

[0338] The dust collecting motor (191) can generate the suction airflow that sucks dust inside the dust bin (220) into the dust collecting unit. The dust collecting motor (191) can be placed at the bottom of the dust collecting unit (170). The dust collecting motor (191) can generate a suction force that can suck dust inside the dust bin (220) of the vacuum cleaner (200), and through this, a suction airflow can be provided to the dust bin (220).

[0339] The suction air current generated by the dust collecting motor (191) is transmitted into the dust bin (220) through the dust collecting unit (170) along the flow path (180) and the dust passage hole (121a), and the dust inside the dust bin (220) is discharged from the dust bin (220) to the dust passage hole (121a) according to the flow of the suction air current and then can be collected in the dust collecting unit (170) through the flow path (180).

[0340] The dust collecting motor (191) can generate suction force by rotation. For example, the dust collecting motor (191) can be formed in a shape similar to a cylinder.

[0341] Meanwhile, in this specification, a virtual dust collecting motor axis line extending the rotation axis of the dust collecting motor (191) can be formed.

[0342] The first filter (192) may be placed between the dust collection unit (170) and the dust collection motor (191). The first filter (192) may be a pre-filter.

[0343] A second filter (not shown) may be placed between the dust collection motor (191) and the outer wall surface (112). The second filter (not shown) may be a HEPA filter.

[0344]

[0345] Meanwhile, the cleaner station (100) may further include a charging unit (128). The charging unit may be placed in the coupling unit (120). The charging unit (128) may be electrically connected to a cleaner (200) coupled to the coupling unit (120). The charging unit (128) may supply power to the battery of the cleaner (200) coupled to the coupling unit (120).

[0346] Additionally, the vacuum cleaner station (100) may further include a side door (not shown). The side door may be positioned in the housing (110). The side door may selectively expose the dust collector (170) to the outside. This allows the user to easily remove the dust collector (170) from the vacuum cleaner station (100).

[0347] In addition, the vacuum cleaner station (100) may further include an exhaust port (162). The exhaust port (162) may be formed in the housing (110). For example, the exhaust port (162) may be formed on the lower side of the housing (110) and may be electrically connected to the dust collecting motor (191). Accordingly, air passing through the dust collecting motor (191) may be discharged to the outside of the housing (110) through the exhaust port (162).

[0348]

[0349] Meanwhile, referring to Fig. 2, the exhaust section (160) is described as follows.

[0350] The vacuum cleaner station (100) may further include an exhaust unit (160).

[0351] The exhaust unit (160) can guide air discharged from the dust collecting motor (191) to the outside of the housing (110). The exhaust unit (160) can connect the internal space and the external space of the housing (110).

[0352] The exhaust unit (160) may include an exhaust path (161). Air discharged from the dust collecting motor (191) may flow through the exhaust path (161). The exhaust path (161) may provide a path through which the air discharged from the dust collecting motor (191) flows. The air flowing through the exhaust path (161) may be discharged to the outside of the housing (110) through an exhaust port (162). Specifically, one end of the exhaust path (161) may be in communication with an internal space in which the dust collecting motor (191) is accommodated in the dust suction module (190), and the other end of the exhaust path (161) may be in communication with an exhaust port (162). For example, the exhaust path (161) may be a path formed along a horizontal direction within the housing (110), and the exhaust port (162) may communicate the inside and the outside of the housing (110). One end of the exhaust passage (161) may be connected to a dust suction module (190), and the other end of the exhaust passage (161) may be connected to an exhaust port (162).

[0353]

[0354] FIG. 9 is a side cross-sectional view of a cleaner system according to a first embodiment of the present invention, FIG. 10a is an enlarged view for explaining in detail an area A illustrated in FIG. 9, FIG. 10b is a drawing for explaining a state in which the second dust storage unit illustrated in FIG. 10a is opened, FIG. 11 is a perspective view for explaining a lower surface of a dust bin of a cleaner according to the first embodiment of the present invention, FIG. 12a is a side cross-sectional view for explaining in detail an opening / closing unit of a cleaner according to the first embodiment of the present invention, FIG. 12b is a side cross-sectional view for explaining a state in which the second dust storage unit illustrated in FIG. 12a is opened, and FIG. 13 is a perspective view for explaining a door of a cleaner station according to the first embodiment of the present invention.

[0355] Referring to FIGS. 9 to 13, the vacuum cleaner system (1) according to the first embodiment of the present invention is described as follows.

[0356] The cleaner system (1) according to the first embodiment of the present invention may include an opening and closing unit (300).

[0357] The opening / closing unit (300) can selectively open / close the second dust storage unit (215b) depending on whether or not a suction airflow is generated. If a suction airflow is generated from the dust suction module (190), the opening / closing unit (300) can open the second dust storage unit (215b). If a suction airflow is not generated from the dust suction module (190), the opening / closing unit (300) can close the second dust storage unit (215b).

[0358] The opening / closing unit (300) can connect the second dust storage unit (215b) and the flow path (180) when suction airflow is generated from the dust suction module (190). Specifically, when the dust suction module (190) generates suction airflow while the cleaner (200) is connected to the coupling unit (120) of the cleaner station (100), the opening / closing unit (300) can connect the second dust storage unit (215b) and the first suction flow path (181).

[0359] According to an embodiment, when an intake airflow is supplied from the outside to the dust bin (220), the opening / closing unit (300) can connect the second dust storage unit (215b) and the external space of the dust bin (220).

[0360] The opening / closing unit (300) may include a guide member (310), a valve member (320), an elastic member (330), and a sealing member (340).

[0361] The guide member (310) is a configuration that guides the movement of the valve member (320). The guide member (310) may extend along the longitudinal direction of the dust bin (220). At least a portion of the guide member (310) may be placed inside the dust bin (220). Specifically, at least a portion of the guide member (310) may be placed in the second dust storage unit (215b).

[0362] The guide member (310) may include a guide bar (311) and a stopper (312).

[0363] The guide bar (311) may be formed to extend in the vertical direction. The guide bar (311) may be arranged in the vertical direction by penetrating the valve member (320). Specifically, the guide bar (311) may be arranged in the vertical direction by penetrating the engaging portion (321). The longitudinal axis of the guide bar (311) may be coincident with or parallel to the axis (a2) of the cyclone flow. The longitudinal axis of the guide bar (311) may be coincident with or parallel to the central axis (a3) ​​of the dustbin. The longitudinal axis of the guide bar (311) may be coincident with or parallel to the suction motor axis (a4).

[0364] The guide bar (311) may be fixedly arranged inside the dustbin (220). Specifically, one end of the guide bar (311) may be fixed to the band member (213bc) of the second cyclone unit (213b). Specifically, the upper end of the guide bar (311) may be fixed to the center of the band member (213bc). The guide bar (311) may extend downward from the center of the band member (213bc). The guide bar (311) may be arranged inside a space formed by the outer peripheral surfaces of a plurality of cyclone bodies (213ba). At this time, the plurality of cyclone bodies (213ba) may be arranged radially with the guide bar (311) as the center.

[0365] Meanwhile, in this specification, the upper side may mean the direction in which the suction motor (216) is arranged based on the second cyclone section (213b), and the lower side may mean the direction in which the second dust storage section (215b) is arranged based on the second cyclone section (213b).

[0366] The stopper (312) may be arranged at the other end of the guide bar (311). Specifically, the stopper (312) may be arranged at the lower end of the guide bar (311). The stopper (312) may be provided to protrude from the lower end of the guide bar (311), and may be provided to protrude in the left and right directions. Accordingly, when the valve member (320) moves downward by a predetermined distance or more, the stopper (312) may interfere with the engaging portion (321) of the valve member (320) to restrict the movement of the valve member (320).

[0367] The stopper (312) may be placed inside the valve member (320). Specifically, the stopper (312) may be placed inside the space formed by the inner surface of the catch (321). Therefore, when a suction airflow is generated in the dust suction module (190) and the valve member (320) moves more than a predetermined distance, the stopper (312) may interfere with the inner surface of the catch (321).

[0368] The valve member (320) can open the second dust storage unit (215b) when an intake airflow is generated. The lower part of the second dust storage unit (215b) can be configured to be open and can be selectively opened and closed by the valve member (320).

[0369] The valve member (320) can move up and down to open and close the dust discharge port (215ba) of the second dust storage unit (215b). The valve member can move upward to close the second dust storage unit (215b) and move downward to open the second dust storage unit (215b).

[0370] A dust discharge port (215ba) may be formed at the bottom of the storage member (215). The dust discharge port (215ba) is configured to guide dust from the second dust storage unit (215b) to the flow path (180). The dust discharge port (215ba) may be closed by a valve member (320), and when an intake airflow is generated in the dust suction module, the valve member (320) may open the dust discharge port (215ba).

[0371] The valve member (320) can open a portion of the dust discharge port (215ba) when suction airflow is generated from the dust suction module (190) (see FIG. 12b). Therefore, compared to a case where the dust discharge port (215ba) is completely opened, when the valve member (320) only partially opens the dust discharge port (215ba), the suction airflow delivered to the second dust storage unit (215b) increases.

[0372] The valve member (320) may be arranged to be movable along the guide member (310). Specifically, the valve member (320) may be arranged to be slidably movable along the guide bar (311). The guide bar (311) may be arranged to penetrate the valve member (320) and may support the upward and downward movement of the valve member (320).

[0373] The valve member (320) may include a catch (321) and a sealing portion (322).

[0374] The catch (321) can restrict the movement of the valve member (320) by interfering with the stopper (312) when the second dust storage unit (215b) is opened. A hole through which a guide bar (311) can pass can be formed in the catch (321). The catch (321) can slide along the guide bar (311) passing through the hole.

[0375] The sealing portion (322) can close a portion of the cover hole (222d) when the discharge cover (222) is closed. The sealing portion (322) can extend from the catch portion (321). The sealing portion (322) can be provided to protrude from an end of the catch portion (321). The sealing portion (322) can be moved upward by the elastic force of the elastic member (330) to pressurize the sealing member (340). In addition, the second dust storage portion (215b) can be closed when the sealing portion (322) presses the sealing member (340).

[0376] The elastic member (330) can generate elastic force in a direction in which the valve member (320) closes the second dust storage unit (215b). The elastic member (330) can have one end and the other end connected to the guide member (310) and the valve member (320), respectively. Specifically, one end of the elastic member (330) can be connected to the stopper (312) of the guide member (310), and the other end of the elastic member (330) can be connected to the catch (321) of the valve member (320). The elastic member (330) can be arranged below the valve member (320).

[0377] The elastic member (330) may be a spring. The elastic member (330) may be arranged along the guide member (310). The elastic member (330) may be formed to surround the guide member (310). Specifically, one end of the elastic member (330) may be fixedly coupled to the stopper (312), and the other end of the elastic member (330) may be fixedly coupled to the catch (321).

[0378] Meanwhile, a cover hole (222d) may be formed in the discharge cover (222) of the cleaner of the cleaner system (1) according to the first embodiment of the present invention. The cover hole (222d) is configured such that the valve member (320) can pass through it when the discharge cover (222) is closed. Specifically, when the dust suction module (190) generates a suction airflow while the discharge cover (222) is closed, the valve member (320) can pass through the cover hole (222d).

[0379] The cover hole (222d) may be formed at the center of the cover body (222a). When the discharge cover (222) is closed, the cover hole (222d) may be formed at a position corresponding to the valve member (320) on the discharge cover (222).

[0380] The diameter of the cover hole (222d) may be formed to be equal to or larger than the diameter of the valve member (320) so that the valve member (320) can pass through the cover hole (222d). Specifically, the diameter of the cover hole (222d) may be formed to be larger than the diameter of the engaging portion (321).

[0381] When no suction airflow is generated in the dust suction module (190), the diameter of the cover hole (222d) can be formed to be the same as the diameter of the sealing portion (322) so that dust is not blown out.

[0382] Since a cover hole (222d) is formed in the discharge cover (222), only the first dust storage unit (215a) can be closed when the discharge cover (222) is closed.

[0383] The sealing member (340) may be positioned on the lower side of the storage member (215) to seal the second dust storage unit (215b) when the valve member (320) closes the second dust storage unit (215b). With this configuration, when the dust suction module (190) does not generate a suction airflow, the valve member (320) may pressurize the sealing member (340) by the elastic force of the elastic member (330), and the second dust storage unit (215b) may be sealed.

[0384] According to an embodiment, the sealing member (340) may be arranged along the inner surface of the cover hole (222d) of the discharge cover (222).

[0385] Meanwhile, a dust discharge port (215ba) may be formed at the center of the sealing member (340). When the suction airflow is supplied to the second dust storage unit (215b), the dust discharge port (215ba) may guide the air of the second dust storage unit (215b) to the cover hole (222d) or to the outside.

[0386] The diameter of the dust discharge port (215ba) may be formed smaller than the diameter of the cover hole (222d). The diameter of the dust discharge port (215ba) may be formed smaller than the diameter of the sealing portion (322). The diameter of the dust discharge port (215ba) may be formed larger than the diameter of the catch portion (321).

[0387] A door hole (141c) may be formed in the door (141). When suction airflow is generated in the dust suction module (190), the valve member (320) may pass through the door hole (141c).

[0388] The diameter of the door hole (141c) may be formed to be larger than the diameter of the valve member (320) so that the valve member (320) can pass through the door hole (141c). Specifically, the diameter of the door hole (141c) may be formed to be larger than the diameter of the sealing portion (322).

[0389] In a closed state of the second dust storage unit (215b), a part of the catch (321) may be placed in the dust discharge port (1215ba), and the sealing portion (322) may be placed in the cover hole (222d). In an open state of the second dust storage unit (215b), a part of the catch (321) may be placed in the dust discharge port (1215ba) and the cover hole (222d), and the sealing portion (322) may be placed in the first suction path (181) through the door hole (141c).

[0390] The dust suction module (190) can generate suction airflow by driving the dust collection motor (191) while the discharge cover (222) and door (141) are closed (see FIG. 10b).

[0391] Specifically, when the dust collecting motor (191) is driven while the discharge cover (222) and the door (141) are closed, external air can be introduced into the space where the suction motor (216) is accommodated through the air outlet of the air discharge cover (217). Thereafter, the air introduced into the space where the suction motor (216) is accommodated can be introduced into the internal space (270a) of the filter. Thereafter, the air introduced into the internal space (270a) of the filter can pass through the filter (270) and be introduced into the external space (270b) of the filter. Thereafter, the air introduced into the external space (270b) of the filter can pass through the vortex finder (213bb) and be introduced into the interior of the second cyclone body (213ba). Thereafter, the air introduced into the interior of the second cyclone body (213ba) can be introduced into the second dust storage unit (1215b). Thereafter, the air introduced into the second dust storage unit (1215b) can sequentially pass through the dust discharge port (1215ba), cover hole (222d), and door hole (141c) and then be introduced into the first suction path (181).

[0392] That is, when the dust collecting motor (191) is driven to generate suction airflow in the vacuum cleaner system according to the first embodiment of the present invention, air in the external space can sequentially flow into the dust collecting unit (170) through the air discharge cover (217), the suction motor (216), the filter (270), the second cyclone unit (213b), the second dust storage unit (215b), the cover hole (222d), the door hole (141c), and the flow path unit (180). In this process, dust accumulated in the filter (270) and the second cyclone unit (213b) can be captured by the dust collecting unit (170) along the suction airflow. In addition, since the suction airflow is supplied while the discharge cover (222) closes the first dust storage unit (215a), there is an effect of increasing the flow rate of the suction airflow delivered to the second dust storage unit (215b) compared to the state in which both the first dust storage unit (215a) and the second dust storage unit (215b) are open.

[0393] Accordingly, the present invention has a feature that it can effectively remove dust accumulated in the filter (270) disposed on the inside of the cyclone body (213ba), the second cyclone section (213b), and / or the upper portion of the dust bin (220) by intensively transmitting the suction airflow to the second dust storage section (215b) while the first dust storage section (215a) is closed.

[0394] Meanwhile, the opening / closing unit (300) can be moved along the longitudinal direction of the dust bin (220). Specifically, the valve member (320) of the opening / closing unit (300) can be moved linearly along the central axis (a3) ​​of the dust bin.

[0395] Referring to Fig. 12b, when a suction airflow is generated in the dust suction module (190), the valve member (320) can move along the dust bin central axis (a3). At this time, the sealing portion (322) of the valve member (320) that was closing the dust discharge port (215ba) can move along the opening direction of the dust discharge port (215ba) (the direction of the dust bin central axis (a3)). When the valve member (320) is moved and the dust discharge port (215ba) is opened, the dust discharge port (215ba) and the cover hole (222d) can be formed in an annular shape.

[0396] Accordingly, all edge areas of the dust discharge port (215ba) can be connected to the first suction path (181) without interference from a separate member. Accordingly, the suction airflow generated from the dust suction module (190) can be uniformly introduced into the second dust storage unit (215b) through the edge area of ​​the dust discharge port (215ba).

[0399] Referring to FIGS. 14 to 20, a cleaner system (2) according to a second embodiment of the present invention will be described as follows.

[0400] A cleaner system (2) according to a second embodiment of the present invention may include a cleaning unit (1300) and a rotation unit (1400).

[0401] Meanwhile, in order to avoid redundant description, except for what is specifically mentioned in the second embodiment of the present invention, other configurations may be cited from the contents of the cleaner system according to the first embodiment of the present invention.

[0402] That is, the second embodiment of the present invention is the same as the first embodiment described above except for the configuration and arrangement of the cleaning unit (1300), storage member (1215), door (141), and rotation unit (1400), so overlapping content is omitted and the differences are mainly described.

[0403] The cleaning unit (1300) can clean the filter (270) by receiving rotational force from the cleaner station (100). Specifically, the cleaning unit (1300) can clean the filter (270) by rotating by receiving rotational force from the drive motor (1420) described below.

[0404] The cleaning unit (1300) may include a guide member (1310), a valve member (1320), an elastic member (1330), a cleaning member (1340), a coupling member (1350), and a discharge member (1360).

[0405] The guide member (1310) can guide the movement of the valve member (1320). The guide member (1310) can rotate the cleaning member (1340) to clean the filter (270).

[0406] At least a portion of the guide member (1310) may be rotatably positioned inside the dust bin (220). Specifically, at least a portion of the guide member (1310) may be rotatably positioned in the second dust storage unit (1215b).

[0407] The guide member (1310) can extend along the length of the dust bin (220).

[0408] The guide member (310) may include a rotating bar (1311), a fixed member (1312), and a support member (1313).

[0409] The rotating bar (1311) may be formed to extend in the vertical direction. The guide bar (1311) may be arranged in the vertical direction by penetrating the valve member (1320). The longitudinal axis of the rotating bar (1311) may be coincident with or parallel to the axis (a2) of the cyclone flow. The longitudinal axis of the rotating bar (1311) may be coincident with or parallel to the central axis (a3) ​​of the dustbin. The longitudinal axis of the rotating bar (1311) may be coincident with or parallel to the suction motor axis (a4).

[0410] The rotating bar (1311) can be rotatably arranged inside the dustbin (220). The second cyclone unit (1213b) can rotatably support one side of the rotating bar (1311). Specifically, the band member (213bc) can rotatably support one side of the rotating bar (1311). In addition, the other side of the rotating bar (1311) can be rotatably supported by a rotating support member (1360b). The rotating support member (1360b) can extend from a discharge member (1360) to be described later.

[0411] The rotating bar (1311) may be arranged to penetrate the center of the band member (213bc). The rotating bar (1311) may be arranged within a space formed by the outer peripheral surfaces of a plurality of cyclone bodies (213ba). In this case, the plurality of cyclone bodies (213ba) may be arranged radially with the guide bar (1311) as the center.

[0412] The fixed part (1312) is a configuration to which the cleaning member (1340) is coupled. The cleaning member (1340) can be fixed to the inside of the fixed part (1312). Specifically, a plurality of fixed parts (1312) can be arranged at the upper end of the guide bar (1311). The fixed part (1312) can be provided to protrude from the upper end of the guide bar (1311). The fixed part (1312) can be formed to be bent at least once.

[0413] The fixed part (1312) may be formed to correspond to the surface of the filter (270). A cleaning member (1340) is coupled to the inside of the fixed part (1312), and the cleaning member (1340) may sweep the surface of the filter (270) while rotating together with the fixed part (1312). At this time, the rotational center axes of the fixed part (1312) and the cleaning member (1340) may coincide with the longitudinal axis of the rotation bar (1311).

[0414] The support member (1313) is a structure that supports the fixed member (1312) so that it can rotate stably. The support member (1313) can be arranged along the rotation radius of the fixed member (1312). The support member (1313) can be formed in a ring shape. The support member (1313) can be formed to match the rotation radius of the fixed member (1312).

[0415] The valve member (1320) can open the second dust storage unit (1215b) when an intake airflow is generated. The lower part of the second dust storage unit (1215b) can be configured to be open and can be selectively opened and closed by the valve member (1320).

[0416] Meanwhile, the lower part of the storage member (1215) of the cleaner system (2) according to the second embodiment of the present invention may have a lower height than the lower part of the dust bin (220). Referring to FIG. 17, it can be seen that the lower part of the dust bin (220) of the cleaner system (2) according to the second embodiment of the present invention protrudes downwards compared to the lower part of the storage member (1215), but this is not the case in the cleaner system (1) according to the first embodiment of the present invention.

[0417] The valve member (1320) can move up and down to open and close the dust discharge port (1215ba) of the second dust storage unit (1215b). The valve member can move upward to close the second dust storage unit (1215b) and move downward to open the second dust storage unit (1215b).

[0418] Specifically, a dust discharge port (1215ba) may be formed at the bottom of the second dust storage unit (1215b). At this time, the dust discharge port (1215ba) may be closed by a valve member (1320), and when an intake airflow is generated in the dust suction module (190), the valve member (1320) may open the dust discharge port (1215ba).

[0419] The valve member (1320) may be arranged to be movable along the guide member (1310). Specifically, the valve member (1320) may be arranged to be slidably movable along the rotation bar (1311). The rotation bar (1311) may be arranged to penetrate the valve member (1320) and may support the upward and downward movement of the valve member (1320).

[0420] The elastic member (1330) can generate an elastic force in a direction in which the valve member (1320) closes the second dust storage unit (1215b). The elastic member (1330) may have one end and the other end connected to the guide member (1310) and the valve member (1320), respectively. Specifically, one end of the elastic member (1330) may be connected to the rotation bar (1311), and the other end may be connected to the valve member (1320). In addition, according to an embodiment, the elastic member (1330) may be arranged along the rotation bar (1311), and one end of the elastic member (1330) may be connected to the rotation support member (1360b), and the other end of the elastic member (1330) may be connected to the valve member (1320).

[0421] The elastic member (1330) may be a spring. The elastic member (1330) may be arranged along the guide member (1310). The elastic member (1330) may be formed to surround the rotation bar (1311). Specifically, one end of the elastic member (1330) may be fixedly coupled to a stopper (1312), and the other end of the elastic member (1330) may be fixedly coupled to the rotation bar (1311) or the rotation support member (1360b).

[0422] The cleaning member (1340) can clean the filter (270) while rotating together with the guide member (1310). The cleaning member (1340) can be placed inside the fixing member (1312). The cleaning member (1340) can be formed to correspond to the surface of the filter (270). The cleaning member (1340) can be a brush. When the rotation bar (1311) of the guide member (1310) rotates, the cleaning member (1340) can rotate together with the fixing member (1312) connected to the rotation bar (1311) to sweep away dust accumulated on the surface of the filter (270).

[0423] The guide member (1310) may include a coupling member (1350). The coupling member (1350) may be a component of the guide member (1310).

[0424] When the door (141) is closed, one side of the guide member (1310) can be coupled with the rotation unit (1400). Specifically, when the door (141) is closed, the coupling member (1350) disposed on one side of the guide member (1310) can be coupled with the rotation unit (1400).

[0425] The coupling member (1350) may be positioned at one end of the rotation bar (1311). The coupling member (1350) may be coupled with the rotation unit (1400) when the door (141) is closed. Specifically, the coupling member (1350) may be coupled with the rotor (1410) of the rotation unit (1400) when the door (141) is closed.

[0426] A coupling groove (1350a) may be formed in the coupling member (1350). At this time, the rotor (1410) of the rotation unit (1400) may be formed to correspond to the coupling groove (1350a). Accordingly, when the door (141) is closed, the rotor (1410) positioned in front of the door (141) may be fitted into the coupling groove (1350a).

[0427] The discharge member (1360) is configured to guide dust discharged through the dust discharge port (1215ba) of the second dust storage unit (1215b) to the flow path (180), and can be placed inside the dust bin (220).

[0428] The discharge member (1360) can divide the space inside the dust bin (220) into a first dust storage unit (1215a) and a discharge path (1360a). That is, the space inside the dust bin (220) can be divided into a first dust storage unit (1215a), a discharge path (1360a), and a second dust storage unit (1215b) by the storage member (1215) and the discharge member (1360).

[0429] The discharge member (1360) may be placed on the lower side of the storage member (1215). The discharge member (1360) may extend from the storage member (1215). At this time, the discharge path (1360a) formed by the internal space of the discharge member (1360) may be communicated with the cover hole (222d).

[0430] With the door (141) closed, the exhaust path (1360a) can connect the second dust storage unit (1215b) and the door hole (141c). Specifically, with the exhaust cover (222) and the door (141) closed, dust discharged from the second dust storage unit (1215b) can pass through the exhaust path (1360a), the cover hole (222d), and the door hole (141c) and enter the path unit (180).

[0431] Meanwhile, a cover hole (222d) may be formed in the discharge cover (222). The cover hole (222d) may be formed in the center of the discharge cover (222). Therefore, even when the discharge cover (222) is closed, only the first dust storage unit (1215a) may be closed. When the discharge cover (222) is closed, at least a portion of the coupling member (1350) may be placed in the cover hole (222d).

[0432] When a suction airflow is generated in the dust suction module (190), the air in the second dust storage unit (1215b) may sequentially pass through the exhaust passage (1360a), the cover hole (222d), and the door hole (141c) and then flow into the first suction passage (181). The diameter of the cover hole (222d) may be formed to be larger than the diameter of the connecting member (1350).

[0433] Meanwhile, the cleaner station of the cleaner system (2) according to the second embodiment of the present invention may include a rotation unit (1400).

[0434] The rotation unit (1400) can be placed on the door (141) and can rotate the cleaning unit (1300) when the door (141) is closed.

[0435] The rotation unit (1400) may include a rotor (1410) and a drive motor (1420).

[0436] The rotor (1410) can be coupled to the cleaning unit (1300) when the door (141) closes the dust passage hole (121a). At least a portion of the rotor (1410) can be positioned in front of the door (141). The rotor (1410) can rotate around the longitudinal axis of the guide member (1310) when the door (141) is closed. Specifically, the rotor (1410) can rotate around the longitudinal axis of the dust bin (220) when the door (141) is closed.

[0437] A door hole (141c) may be formed in the door (141). The door hole (141c) may guide dust from the second dust storage unit (1215b) to the flow path (180) when an intake airflow is generated while the door (141) is closed.

[0438] When the vacuum cleaner (200) is connected to the coupling part (120) and a suction airflow is generated, the door hole (141c) can be connected to the cover hole (222d). When the dust collecting motor (191) is driven and a suction airflow is generated while the door (141) is closed, the valve member (320) can pass through the door hole (141c), and at least a portion of the valve member (320) can be arranged in the first suction path (181).

[0439] The rotor (1410) may be positioned so that at least a portion thereof protrudes forward of the door (141) by penetrating the door hole (141c). The diameter of the door hole (141c) may be formed to be larger than the diameter of the rotor (1410). Therefore, when suction force is generated in the dust suction module (190), air from the second dust storage unit (1215b) may pass through the door hole (141c).

[0440] The driving motor (1420) can provide rotational force to the rotor (1410). The driving motor (1420) can be placed at the rear of the door (141). At this time, the dust suction module (190) can generate a suction airflow after the driving motor (1420) is driven. Specifically, when the driving motor (1420) is driven and the cleaning member (1340) rotates to sweep away dust accumulated on the filter (270), the dust collecting motor (191) is then driven and the dust swept away from the filter (270) is sucked into the dust collecting unit (170).

[0441] The vacuum cleaner system (2) according to the second embodiment of the present invention can generate suction airflow by driving the dust collection motor (191) while the discharge cover (222) and the door (141) are closed (see Fig. 15b). At this time, the dust collection motor (191) can be driven after the driving motor (1420) of the rotation unit (1400) has finished driving.

[0442] Specifically, when the drive motor (1420) of the rotation unit (1400) is driven while the door (141) is closed, the rotor (1410) can rotate, and when the rotation unit (1400) coupled to the rotor (1410) rotates, the cleaning member (1340) can sweep away dust accumulated on the outer surface of the filter (270). Then, when the dust collection motor (191) is driven while both the discharge cover (222) and the door (141) are closed, external air can be introduced into the space where the suction motor (216) is accommodated through the air outlet of the air discharge cover (217). Then, the air introduced into the space where the suction motor (216) is accommodated can be introduced into the inner space (270a) of the filter. Then, the air introduced into the inner space (270a) of the filter can pass through the filter (270) and be introduced into the outer space (270b) of the filter. Thereafter, the air introduced into the external space (270b) of the filter may pass through the vortex finder (213bb) and be introduced into the interior of the second cyclone body (213ba). Thereafter, the air introduced into the interior of the second cyclone body (213ba) may be introduced into the second dust storage unit (1215b). Thereafter, the air introduced into the second dust storage unit (1215b) may pass through the dust discharge port (1215ba) and be introduced into the exhaust path (1360a). Thereafter, the air introduced into the exhaust path (1360a) may pass through the cover hole (222d) and the door hole (141c) in sequence and be introduced into the first suction path (181).

[0443] That is, when the dust collecting motor (191) is driven to generate suction airflow in the vacuum cleaner system according to the first embodiment of the present invention, air in the external space can sequentially flow into the dust collecting unit (170) through the air discharge cover (217), the suction motor (216), the filter (270), the second cyclone unit (213b), the second dust storage unit (1215b), the discharge path (1360a), the cover hole (222d), the door hole (141c), and the path unit (180). In this process, dust accumulated in the filter (270) and the second cyclone unit (213b) can be captured by the dust collecting unit (170) along the suction airflow. In addition, since the suction airflow is supplied while the discharge cover (222) closes the first dust storage unit (1215a), there is an effect of increasing the flow rate of the suction airflow delivered to the second dust storage unit (1215b) compared to the state in which both the first dust storage unit (1215a) and the second dust storage unit (1215b) are open.

[0444]

[0445] FIG. 21 is a side cross-sectional view of a vacuum cleaner system according to a third embodiment of the present invention, FIG. 22a is an enlarged view for explaining in detail the area C illustrated in FIG. 21, and FIG. 22b is a drawing for explaining a state in which the second dust storage unit illustrated in FIG. 22a is opened.

[0446] Referring to FIGS. 21 to 22b, a cleaner system (3) according to a third embodiment of the present invention is described as follows.

[0447] A cleaner system (3) according to a third embodiment of the present invention may include a cleaning unit (2300) and a rotation unit (2400).

[0448] Meanwhile, in order to avoid duplicate explanation, except for what is specifically mentioned in the third embodiment of the present invention, other configurations may be referred to the contents of the cleaner system (2) according to the second embodiment of the present invention.

[0449] That is, the cleaner system (3) according to the third embodiment of the present invention is identical to the cleaner system (2) according to the second embodiment of the present invention except for the configuration and arrangement of the rotation unit (2400), so overlapping content is omitted and the differences are mainly explained.

[0450] The rotation unit (2400) according to the third embodiment of the present invention can be placed inside the housing (110) and can rotate the cleaning unit (1300) while the door (141) is open.

[0451] The rotation unit (1400) may include a hinge member (2410), a rotor (2420), and a drive motor (not shown).

[0452] The hinge member (2410) is configured to couple the rotor (2420) to the cleaning unit (1300). The hinge member (2410) can be rotatably installed inside the housing (110). When the hinge member (2410) is rotated toward the dust passage hole (121a) while the door (141) is open, the rotor (2420) can be coupled with the coupling member (1350) of the cleaning unit (1300).

[0453] The rotor (2420) may be placed on the hinge member (2410). The rotor (2420) may be coupled with the cleaning unit (1300) when the hinge member (2410) rotates toward the dust passage hole (121a). The rotor (2420) may rotate around the longitudinal axis of the rotation bar (1311) while coupled with the coupling member (1350) of the cleaning unit (1300).

[0454] A driving motor (not shown) can provide rotational force to a rotor (2420). The driving motor (not shown) can be disposed on a hinge member (2410) or disposed inside a housing (110). At this time, the dust suction module (190) can generate a suction airflow after the driving motor is driven. Specifically, when the driving motor is driven and the cleaning member (1340) rotates to sweep away dust accumulated on the filter (270), the dust collection motor (191) is then driven so that the dust swept away from the filter (270) is sucked into the dust collection unit (170).

[0455] Unlike the cleaner system according to the second embodiment of the present invention, the rotary unit (2400) of the cleaner system (3) according to the third embodiment of the present invention has a difference in that it can be combined with the cleaning unit (1300) while the door (141) is open.

[0456] The vacuum cleaner system (3) according to the third embodiment of the present invention can drive the dust collection motor while the discharge cover (222) is closed to deliver suction airflow to the second dust storage unit (1215b) (see FIG. 22b).

[0457] Specifically, when the dust collecting motor is driven while the discharge cover (222) and the door (141) are closed, external air can be introduced into the space where the suction motor (216) is accommodated through the air outlet of the air discharge cover (217). Thereafter, the air introduced into the space where the suction motor (216) is accommodated can be introduced into the internal space (270a) of the filter. Thereafter, the air introduced into the internal space (270a) of the filter can pass through the filter (270) and be introduced into the external space (270b) of the filter. Thereafter, the air introduced into the external space (270b) of the filter can pass through the vortex finder (213bb) and be introduced into the interior of the second cyclone body (213ba). Thereafter, the air introduced into the interior of the second cyclone body (213ba) can be introduced into the second dust storage unit (1215b). Thereafter, the air introduced into the second dust storage unit (1215b) can pass through the dust discharge port (1215ba) and be introduced into the exhaust path (1360a). Thereafter, the air introduced into the exhaust path (1360a) can pass through the cover hole (222d) and the dust passage hole (121a) in sequence and be introduced into the first suction path (181).

[0458] That is, when the dust collecting motor (191) is driven to generate suction airflow in the cleaner system (3) according to the third embodiment of the present invention, air in the external space may sequentially pass through the air discharge cover (217), the suction motor (216), the filter (270), the second cyclone unit (213b), the second dust storage unit (1215b), the discharge path (1360a), the cover hole (222d), the dust passage hole (121a), and the path unit (180) and then be introduced into the dust collecting unit (170). In this process, dust accumulated in the filter (270) and the second cyclone unit (213b) may be captured by the dust collecting unit (170) along the suction airflow. In addition, since the suction airflow is supplied while the discharge cover (222) closes the first dust storage unit (1215a), there is an effect of increasing the flow rate of the suction airflow delivered to the second dust storage unit (1215b) compared to the state in which both the first dust storage unit (1215a) and the second dust storage unit (1215b) are open.

[0472] Meanwhile, when emptying of the dustbin (220) is completed, the control unit (400) can rotate the door motor (142) in the reverse direction to close the door (141).

[0473] The control unit (400) can operate the cover opening motor (152) to open the discharge cover (222) of the vacuum cleaner (200) when it determines that the door (141) is open.

[0474] The cover opening detection unit (155f) can transmit a signal indicating that the discharge cover (222) is opened when the guide frame (151e) reaches a predetermined opening position. The control unit (400) can receive a signal indicating that the discharge cover (222) is opened from the cover opening detection unit (155f) and determine that the discharge cover (222) is opened. When the control unit (400) determines that the discharge cover (222) is opened, the control unit (400) can stop the operation of the cover opening motor (152).

[0475] The control unit (400) can drive the dust collection motor (191) to suck up dust inside the dust bin (220).

[0476] The control unit (400) can operate the display unit (410) to display the dustbin emptying status and charging status of the vacuum cleaner (200).

[0477] Meanwhile, the cleaning station (100) of the present invention may include a display unit (410).

[0478] The display unit (410) may be placed in the housing (110), or may be placed in a separate display device, and may be provided in a terminal including a mobile phone.

[0479] The display unit (410) may be configured to include at least one of a display panel capable of outputting characters and / or figures, and a speaker capable of outputting voice signals and sounds. The user can easily grasp the status of the current administrative operation, the remaining time, etc. through the information output through the display unit.

[0480] Meanwhile, the cleaner station (100) according to an embodiment of the present invention may include a memory (430). The memory (430) may include various data for driving and operating the cleaner station (100).

[0481] Meanwhile, the cleaner station (100) according to an embodiment of the present invention may include an input unit (440).
