Description

Vacuum cleaner and vacuum cleaner system including the same

[0001] The present invention relates to a vacuum cleaner and a vacuum cleaner system including the same, and more specifically, to a vacuum cleaner and a vacuum cleaner system including the same that can perform cleaning by sucking in external air containing dust and separating the dust in the air.

[0002] Generally, a vacuum cleaner is a home appliance that uses electricity to suck up air to collect small debris or dust and fill it into a dust bin inside the product, and it is commonly referred to as a vacuum cleaner.

[0003] These vacuum cleaners can be classified into manual vacuum cleaners, which are used for cleaning by moving the vacuum cleaner directly, and automatic vacuum cleaners, which are used for cleaning by driving on their own. Manual vacuum cleaners can be classified into canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick-type vacuum cleaners, depending on the form of the vacuum cleaner.

[0004] In the past, canister-type vacuum cleaners were widely used for household use, but recently, handheld and stick vacuum cleaners, which offer improved convenience by providing the dust bin and the main body as a single unit, are becoming more popular.

[0005] Canister-type vacuum cleaners have the main body and the suction nozzle connected by a rubber hose or pipe, and depending on the case, a brush can be attached to the nozzle for use.

[0006] Hand vacuum cleaners maximize portability; however, because they are lightweight but short, the cleaning area may be limited while sitting. Therefore, they are used to clean localized areas such as desks, sofas, or inside cars.

[0007] Stick vacuums can be used while standing, allowing for cleaning without bending over. This makes them advantageous for cleaning large areas. While handheld vacuums are used for cleaning narrow spaces, stick vacuums can clean larger areas and reach high places that are out of reach. Recently, stick vacuums are also being offered in modular types, allowing users to actively switch between different types of vacuums for various tasks.

[0008] In relation to a vacuum cleaner that fills a dust bin with dust from the air by sucking in external air as described above, International Patent Publication No. 2023-089298 (hereinafter referred to as 'Prior Art 1') discloses a dust separator.

[0009] Specifically, the invention discloses a first filter for separating dust from air introduced through an air inlet, a second filter for separating dust again from air that has passed through the first filter, and a wiper blade that moves up and down to directly remove dust accumulated on the first filter while simultaneously indirectly removing dust accumulated on the second filter.

[0010] However, the vacuum cleaner of prior art 1 has a problem in that it is not efficient at removing dust accumulated on the second filter, as the wiper blade moves up and down to directly sweep away dust accumulated on the outer surface of the first filter, but the protrusion connected to the wiper blade only indirectly removes dust accumulated on the inner surface of the second filter by striking the outer surface of the second filter.

[0011] In addition, when multiple cleaning elements, such as wiper blades, are installed and used, bending deformation may occur due to the pressure applied to these cleaning elements. However, the cleaning device of Prior Art 1 has a problem in that it does not consider a structure to solve such bending deformation.

[0012] In addition, Korean Registered Patent No. 10-2676424 (hereinafter referred to as 'Prior Art 2') discloses a vacuum cleaner.

[0013] Specifically, the invention discloses a housing having a suction opening, first and second cyclone sections for separating air and dust, and a dust container for storing dust separated from air in the cyclone sections; a guide wall for guiding air flow within the housing; a frame that can move between a first position and a second position within the housing and surrounds the guide wall at the first position; a filter section arranged to surround the axis of the cyclone flow; and a cleaning section coupled to the frame and in contact with the filter section during the process of moving from the first position to the second position.

[0014] However, the vacuum cleaner of prior art 2 discloses only the structure of a cleaning unit capable of removing dust between the first and second cyclone sections, and does not consider a structure capable of removing dust collected in a pre-filter that filters dust in the air passing through the cyclone sections. Therefore, if dust collected in the pre-filter is not removed, there is a problem that the suction performance of the vacuum cleaner is reduced.

[0015] As described above, vacuum cleaners that perform cleaning by drawing in external air and separating dust from the air face a challenge that must be addressed to effectively remove dust collected in the filter and maintain adequate suction performance at all times.

[0016] However, conventional vacuum cleaners have limitations in that they cannot adequately solve these problems.

[0017] The present invention aims to solve the above-mentioned problems associated with a vacuum cleaner that performs cleaning by sucking in external air and separating dust from the air.

[0018] Specifically, the present invention aims to provide a vacuum cleaner in which the structure for removing dust collected in a filter is made of a more stable structure, so that the suction performance for cleaning can always be properly maintained during use.

[0019] In addition, the present invention aims to provide a vacuum cleaner capable of minimizing breakdowns or damage during use by ensuring that the structure for removing dust collected in the filter is designed so as not to be subjected to improper pressure or impact due to user error or misoperation.

[0020] In addition, the present invention aims to provide a vacuum cleaner in which dust removal from a filter can be performed more effectively by making the structure for removing dust collected in the filter such that the dust can be directly ejected from the filter.

[0021] In addition, the present invention aims to provide a vacuum cleaner that enables smooth dust removal from a filter by better transmitting the force applied for operation, even when the structure for removing dust collected in the filter due to a large amount of dust has accumulated is not moving well.

[0022] In addition, the present invention aims to provide a vacuum cleaner in which the structure for removing dust collected in a filter is configured to guide a certain portion of the airflow, thereby allowing the airflow to spread more evenly during the process in which external air is drawn into the vacuum cleaner, the dust is separated, and then discharged.

[0023] In addition, the present invention aims to provide a vacuum cleaner system that is structured to prevent dust removed from the filter from scattering back and being re-collected on the filter, thereby enabling more effective dust removal from the filter and maintaining appropriate suction performance for cleaning at all times.

[0024]

[0025] The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0026] To achieve the above or other objectives, a vacuum cleaner according to one aspect of the present invention is configured so that the operation of a filter cleaning unit for removing dust collected in a pre-filter unit is performed more stably.

[0032] In addition, according to one aspect of the present invention, when combining the main body and the pre-filter part, the pre-filter part can be inserted into the main body and then rotated to combine them.

[0033] In addition, in a vacuum cleaner according to one aspect of the present invention, the gap of the insertion groove may be formed to be greater than the rotational distance of the pre-filter part that rotates after being inserted into the main body.

[0034] In addition, in a vacuum cleaner according to one aspect of the present invention, a vacuum cleaner cover may be fitted and coupled to the perimeter of the upper surface of a vacuum cleaner support.

[0035] In addition, a vacuum cleaner according to one aspect of the present invention can be coupled by inserting a coupling projection of a vacuum cleaner cover into a coupling groove of a vacuum cleaner support.

[0036] In addition, a vacuum cleaner according to one aspect of the present invention may include a filter cleaner, a filter cleaning frame, and a filter cleaning body.

[0037] In addition, according to one aspect of the present invention, the cleaner may have a cleaner cover formed in a shape that covers the upper surface of the filter cleaning frame.

[0038] In addition, a vacuum cleaner according to one aspect of the present invention can remove dust stored in a dust bin by having a dust cleaner unit that moves up and down between a dust bin and a cyclone unit.

[0039] In addition, a vacuum cleaner according to one aspect of the present invention may be connected so that a filter cleaning unit is raised together with a dust cleaning unit.

[0040] In addition, a vacuum cleaner according to one aspect of the present invention is configured such that a filter cleaning unit is formed in a structure that can directly contact the surface where dust is collected in the pre-filter unit along the air movement path. Specifically, dust is collected on the inner surface of the pre-filter unit where air moves from the inside to the outside and is filtered, and the filter cleaning unit is configured to move up and down to remove the collected dust from the inner surface of the pre-filter unit.

[0041] In addition, a vacuum cleaner system according to one aspect of the present invention is configured to prevent dust removed from the pre-filter section from scattering again and being re-collected in the pre-filter section. Specifically, the vacuum cleaner station is configured to suck in and collect dust removed from the inner surface of the pre-filter section by a filter cleaning section.

[0042] In addition, a vacuum cleaner system according to one aspect of the present invention may be configured such that the inner diameter of the pre-filter section is larger than or equal to the inner diameter of the pre-filter inlet.

[0069]

[0070] FIG. 1 is a perspective view showing a vacuum cleaner (1000) according to one embodiment of the present invention. FIG. 2a is a cross-sectional view showing a vacuum cleaner (1000) according to one embodiment of the present invention. FIG. 2b is a drawing showing the filter cleaner (510) in a lowered state in the drawing shown in FIG. 2a.

[0071] Referring to FIGS. 1, FIGS. 2a and FIGS. 2b, a vacuum cleaner (1000) according to one embodiment of the present invention is schematically described as follows.

[0072] The vacuum cleaner (1000) may refer to a vacuum cleaner (1000) that is manually operated by a user. For example, the vacuum cleaner (1000) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0073] Meanwhile, in one embodiment of the present invention, the direction of the vacuum cleaner (1000) can be defined based on when the bottom surface (lower side) of the battery (140) is placed on the ground.

[0074] In this case, the front may refer to the direction in which the suction unit (200) is positioned relative to the suction motor unit (600), and the rear may refer to the direction in which the handle (130) is positioned relative to the suction motor unit (600). Additionally, when looking at the suction unit (200) from the suction motor unit (600), the direction positioned to the right may be called the right side, and the direction positioned to the left may be called the left side. Furthermore, in one embodiment of the present invention, the upper side and the lower side may be defined along a direction perpendicular to the ground when the bottom surface (lower side) of the battery (140) is placed on the ground.

[0075] The vacuum cleaner (1000) may include a main body (100). The main body (100) may have a suction unit (200), a dust bin (110), an air outlet (120), a handle (130), a battery (140), and an operating unit (150) formed in a part of the main body housing that forms the main exterior of the vacuum cleaner (1000). Additionally, a cyclone unit (300), a pre-filter unit (400), a filter cleaning unit (500), a suction motor unit (600), and a dust cleaning unit (700) may be arranged inside the main body (100).

[0076] The suction part (200) may be positioned inside the dust bin (110). For example, the suction part (200) may be formed in the shape of a pipe with an open interior. The suction part (200) may be coupled with an extension tube (not shown). Such a suction part (200) may provide a suction path through which air containing dust can flow.

[0077] The suction part (200) can be coupled to the cyclone part (300). In this case, at least a portion of the suction part (200) can be positioned inside the cyclone part (300). The suction part (200) can be formed in a bent shape. One end of the suction part (200) can be formed to penetrate the discharge cover. The other end of the suction part (200) can be formed to penetrate the outer surface of the cyclone part (300). Accordingly, air sucked in from the outside through the suction part (200) can flow through the suction path and be discharged into the dust bin (110).

[0078] A vacuum cleaner (1000) according to one embodiment of the present invention may have at least one cyclone section (300) capable of separating dust by cyclone flow. For example, the vacuum cleaner (1000) may include a first cyclone section and a second cyclone section.

[0079] The first cyclone section is configured to apply the principle of a dust collector that utilizes centrifugal force to separate dust sucked into the interior of the main body (100) through the suction section (200). That is, the first cyclone section refers to a space where cyclone flow occurs along the inner surface of the dust container (110), and the first cyclone section may refer to a part of the space inside the dust container (110).

[0080] The first cyclone section can be connected to the suction section (200). The first cyclone section can separate dust sucked into the interior through the suction section (200). The space inside the first cyclone section can be connected to the space inside the dust bin (110).

[0081] The cyclone flow generated in the first cyclone section may be due to the suction force of the suction motor section (600).

[0082] The space inside the first cyclone section can be connected to the suction section (200). Air and dust sucked in through the suction section (200) flow along the inner surface of the first cyclone section, thereby allowing cyclone flow to occur in the space inside the first cyclone section.

[0083] The second cyclone section can separate dust again from the air discharged from the first cyclone section. That is, the second cyclone section can filter out small dust particles from the air that passed through the first cyclone section that the first cyclone section failed to filter out.

[0084] At this time, the second cyclone section may be located inside the first cyclone section so that the size of the vacuum cleaner (1000) is minimized. The second cyclone section may be positioned below the suction motor section (600). The first cyclone section and the second cyclone section may be positioned inside the dust bin (110).

[0085] The second cyclone section may include a plurality of cyclone bodies arranged in parallel. Accordingly, air discharged from the first cyclone section may be divided and pass through the plurality of cyclone bodies. That is, the cyclone flow generated in the second cyclone section may be formed inside the cyclone bodies.

[0086] A storage member in which dust separated from the second cyclone section is stored may be disposed inside the dust bin (110). This storage member may be in contact with the upper surface of the discharge cover, and the lower side of the storage member may be open.

[0087] The storage member can divide the space inside the dust bin (110) into a first dust storage section in which dust separated from the first cyclone section is stored, and a second dust storage section in which dust separated from the second cyclone section is stored.

[0088] The discharge cover can open and close the first dust storage unit and the second dust storage unit together. That is, the first dust storage unit and the second dust storage unit can be exposed to the outside together.

[0089] The suction motor unit (600) can generate a suction airflow that sucks in air. The suction motor unit (600) can be placed inside the main body (100).

[0090] The suction motor unit (600) can generate suction force by rotation. At this time, cyclone flow can be generated by the suction force of the suction motor unit (600).

[0091] An air outlet (120) for discharging air sucked in by the suction force of the suction motor unit (600) may be formed in the main body housing. A flow guide may be disposed in the main body housing. The flow guide may guide the flow of air discharged through the air outlet (120).

[0092] The handle (130) can be grasped by the user. The handle (130) can be positioned at a predetermined angle with the main body housing, the suction motor part (600), or the cyclone part (300).

[0093] The control unit (150) may be placed in the main body housing. The control unit (150) may be placed on the outer surface of the main body housing. The control unit (150) may be composed of a plurality of buttons, and when a user presses a corresponding button, a command corresponding to that button can be executed. The user can input a command to operate or stop the vacuum cleaner (1000) through the control unit (150).

[0094] The vacuum cleaner (1000) may include a dust bin (110). The dust bin (110) may be connected to a suction part (200). A cyclone part (300) may be located inside the dust bin (110). The dust bin (110) may store dust separated from the cyclone part (300).

[0095] The dustbin (110) may include a discharge cover. The discharge cover may be placed on the lower side of the dustbin (110).

[0096] The vacuum cleaner (1000) may include a battery (140). The battery (140) stores electrical energy and can supply power to each component, including the suction motor unit (600) of the vacuum cleaner (1000). The battery (140) may be placed at the bottom of the handle (130). The battery (140) may be placed at the bottom of the dust bin (110). That is, the suction motor unit (600) and the battery (140) are positioned so as not to overlap in the front-rear direction, and their heights may also be positioned differently.

[0097] With respect to the handle (130), the heavy suction motor part (600) is positioned on the upper side of the handle (130), and the light battery (140) is positioned on the lower side of the handle (130), so the weight can be evenly distributed throughout the vacuum cleaner (1000).

[0098] By doing so, when the user holds the handle (130) and cleans, it is possible to prevent strain on the user's wrist.

[0099] When the battery (140) is attached to the main body (100), the lower surface of the battery (140) may be exposed to the outside. Since the battery (140) may be placed on the floor when the vacuum cleaner (1000) is placed on the floor, the battery (140) can be immediately detached from the main body (100). Additionally, since the lower surface of the battery (140) is exposed to the outside and comes into direct contact with the outside air of the battery (140), the cooling performance of the battery (140) may be improved.

[0100] Meanwhile, if the battery (140) is fixed integrally to the main body (100), the structure for attaching and detaching the battery (140) and the main body (100) can be reduced, so the overall size of the vacuum cleaner (1000) can be reduced and it can be made lighter.

[0101] The vacuum cleaner (1000) may include a first filter section. The first filter section can filter air discharged from a first cyclone section. The first filter section can guide air, from which dust has been separated while passing through the first cyclone section, to a second cyclone section.

[0102] Hereinafter, the flow of air flowing through the path of a vacuum cleaner (1000) according to an embodiment of the present invention will be described.

[0103] First, when the suction motor unit (600) is operated, external air can be drawn into the interior of the dust bin (110) through the suction unit (200).

[0104] Air in which dust has been separated by the first cyclone section inside the dust bin (110) can flow into the cyclone body of the second cyclone section after passing through the first filter section. The air flowing into the inside of the cyclone body can flow upward and pass through the vortex finder after falling while forming a swirling flow. The air passing through the vortex finder can have dust filtered in the pre-filter section (400). The air filtered of dust in the pre-filter section (400) can flow toward the suction motor section (600) located downstream of the suction airflow. The air passing through the suction motor section (600) can be discharged to the outside through the air outlet (120).

[0105] FIG. 3 is a drawing showing the pre-filter section (400) and the filter cleaning section (500) in more detail in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 4a is a drawing showing the state in which the pre-filter section (400) is separated from the main body (100) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 4b is a drawing showing the state in which the filter cleaning section (500) is separated from the main body (100) in the drawing shown in FIG. 4a. FIG. 5a is a drawing showing the state in which the pre-filter section (400) is separated from the main body (100) and the cleaner support body (520) and cleaner cover (530) are omitted in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 5b is a drawing showing the state in which the pre-filter section (400), the cleaner support body (520), and the cleaner cover (530) are separated from the main body (100) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 6 is a drawing showing the filter cleaner (510) illustrated in FIG. 5a in more detail. FIG. 7 is a cross-sectional view showing the filter cleaner (510) illustrated in FIG. 6.

[0106] In this case, FIGS. 5a, 6, and 7 are illustrated with the cleaner support body (520) and cleaner cover (530) omitted in order to show the structure of the filter cleaner (510) in detail.

[0107] A vacuum cleaner (1000) according to one embodiment of the present invention includes a main body (100), a suction part (200), a cyclone part (300), a pre-filter part (400), and a filter cleaning part (500). In this case, the filter cleaning part (500) includes a cleaner support body (520) and a filter cleaner (510).

[0108] The main body (100) is a part that includes a dust bin (110) in which dust is stored, and forms the main exterior of the vacuum cleaner (1000) according to the present embodiment, so that main components can be arranged inside and outside.

[0109] Here, the dust container (110) may be a part where dust in the air separated during the process of sucking in external air containing dust is stored.

[0110] The suction part (200) is a part that guides external air containing dust into the dust container (110), and can guide the sucked air into the dust container (110) by connecting the external space and the dust container (110) from the main body (100).

[0111] The cyclone section (300) is a part that separates dust from the air introduced from the intake section (200), and can separate dust in the air introduced by the cyclone flow. In this case, the cyclone section (300) may consist of at least one or more.

[0112] The pre-filter section (400) is installed on the path of air passing through the cyclone section (300) to filter dust in the air, and can filter dust from the air that has not been separated by the cyclone flow of the cyclone section (300).

[0113] For example, as described above, the first filter unit may be positioned, at least partially, inside the dust bin (110) and may filter dust from the air introduced through the suction unit (200). The first filter unit may be positioned to surround the cyclone unit (300). In this case, the first filter unit may be a mesh filter. Additionally, when the suction motor unit (600) is driven, the suction airflow may pass from the outside to the inside of the first filter unit.

[0114] Additionally, the pre-filter section (400) can filter dust from the air that has passed through the cyclone section (300) (first filter section). In this case, the pre-filter section (400) may be formed in a shape similar to a cylinder with an open interior. Furthermore, when the suction motor section (600) is driven, the suction airflow can pass from the inside to the outside of the pre-filter section (400).

[0115] The cyclone section (300) (first filter section) and the pre-filter section (400) can be arranged in an up-and-down direction along the central axis of the dust bin (110).

[0116] In this case, the pre-filter section (400) may include a pre-filter (410) for filtering dust and a filter cover (420) on which the pre-filter (410) is installed and supported. In particular, the upper surface of the filter cover (420) may be exposed to the outside to form part of the upper surface of the vacuum cleaner (1000) according to the present embodiment.

[0117] The filter cleaning unit (500) is a part that removes dust collected in the pre-filter unit (400) from the pre-filter unit (400), and can be structured to remove dust collected in the pre-filter unit (400).

[0118] If dust is continuously collected in the pre-filter section (400), the suction airflow may not be smooth, and there is a concern that the suction performance of the vacuum cleaner (1000) may be reduced. Therefore, it is necessary to frequently remove the dust collected in the pre-filter section (400) while using the vacuum cleaner (1000).

[0119] In this case, since it is very cumbersome for the user to remove dust after separating the pre-filter unit (400) from the main body (100) every time, it may be desirable to remove dust collected in the pre-filter unit (400) through a filter cleaning unit (500) installed in the main body (100).

[0120] In relation to the structure of the filter cleaning unit (500) as described above, the cleaner support body (520) is a part installed inside the pre-filter unit (400) and can support the filter cleaner (510) that is raised and lowered.

[0121] The filter cleaner (510) is a part that moves up and down between the inner surface of the pre-filter section (400) and the outer surface of the cleaner support (520) to remove dust collected in the pre-filter section (400), and can remove the collected dust by physically contacting the surface of the pre-filter section (400) where dust is collected.

[0122] That is, as shown in FIG. 3 and FIG. 4a, a cleaner support (520) is installed inside the pre-filter section (400), and a filter cleaner (510) can be placed between the inner surface of the pre-filter section (400) and the outer surface of the cleaner support (520).

[0123] And, a filter cleaner (510) positioned between the inner surface of the pre-filter section (400) and the outer surface of the cleaner support (520) can be raised and lowered along the longitudinal direction and sweep down the inner surface of the pre-filter section (400).

[0124] Accordingly, dust collected on the inner surface of the pre-filter section (400) can be removed by being detached from the pre-filter section (400) through physical contact with the filter cleaner (510).

[0125] In particular, since the filter cleaner (510) can be supported on the outer surface of the cleaner support body (520) when the filter cleaner (510) is raised and lowered, the raising and lowering of the filter cleaner (510) can be performed more stably.

[0126] In this regard, if there is no cleaner support body (520), there is a concern that the lifting and lowering of the filter cleaner (510) may become relatively unstable. In particular, as shown in FIGS. 5a to 7, when the filter cleaner (510) is installed in a cantilevered structure, the lifting and lowering of the filter cleaner (510) may be very unstable in that the filter cleaner (510) is supported only on one side.

[0127] For example, in the absence of the cleaner support body (520), the filter cleaner (510) may not be able to maintain a parallel state and may not make even contact with the entire inner surface of the pre-filter section (400). Additionally, as the filter cleaner (510) moves further away from the supported part, the physical force in contact with the inner surface of the pre-filter section (400) becomes relatively weaker, so dust removal may not be effectively achieved.

[0128] Accordingly, the vacuum cleaner (1000) according to the present embodiment can be configured to install a cleaner support body (520) so that the filter cleaner (510) is supported by the cleaner support body (520) and moves up and down, thereby enabling stable lifting of the filter cleaner (510).

[0129] In this way, in a vacuum cleaner (1000) according to one embodiment of the present invention, since a filter cleaner (510) that removes dust collected in a pre-filter unit (400) is raised and lowered between the inner surface of the pre-filter unit (400) and the outer surface of the cleaner support (520), dust removal from the pre-filter unit (400) is stably achieved through the raising and lowering of the filter cleaner (510), so that the suction performance for cleaning can always be maintained in an appropriate state.

[0130] In a vacuum cleaner (1000) according to one embodiment of the present invention, the filter cleaning unit (500) may further include a cleaning cover (530) that covers the upper surface of a filter cleaner (510) and is coupled to a cleaning support body (520).

[0131] That is, as shown in FIGS. 3 and 4a, the cleaner cover (530) covers the upper surface of the filter cleaner (510) and is coupled to the cleaner support body (520), so that the filter cleaner (510) is covered by the cleaner cover (530) while the pre-filter part (400) is separated from the main body (100).

[0132] If, as shown in FIGS. 5a to 7, the cleaner cover (530) is not present, the filter cleaner (510) can be directly exposed to the outside with the pre-filter section (400) separated from the main body (100).

[0133] Such a filter cleaner (510) may be deformed or damaged due to external impact or contact with a user, and thus the function of cleaning the pre-filter part (400) may not be performed smoothly.

[0134] In addition, when the dust cleaner (700) and the filter cleaner (510) described later are connected, there is a risk that not only the filter cleaner (510) but also the dust cleaner (700) may be deformed or damaged due to external impact applied to the filter cleaner (510) or contact with a user.

[0135] Accordingly, the vacuum cleaner (1000) according to the present embodiment may be configured to protect the filter cleaner (510) while the pre-filter part (400) is separated from the main body (100) by installing a cleaner cover (530).

[0136] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention is structured such that the cleaner cover (530) covers the upper surface of the filter cleaner (510) and is coupled to the cleaner support body (520), so that even when the pre-filter part (400) is separated from the main body (100), the external exposure of the filter cleaner (510) is minimized, thereby preventing malfunction or damage.

[0137] FIG. 8a is a drawing showing a filter cleaning unit (500) in more detail in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 8b is a drawing showing the filter cleaning unit (510) in a lowered state in the drawing shown in FIG. 8a. FIG. 9a is a cross-sectional view showing the filter cleaning unit (500) shown in FIG. 8a. FIG. 9b is a drawing showing the filter cleaning unit (510) in a lowered state in the drawing shown in FIG. 9a.

[0138] In a vacuum cleaner (1000) according to one embodiment of the present invention, the vacuum cleaner support (520) may be formed in a tubular shape that is penetrated along the longitudinal direction.

[0139] That is, as shown in FIGS. 8a and 9a, the cleaner support (520) is formed as a tubular structure extending along the lifting direction of the filter cleaner (510), so that the filter cleaner (510) can be supported on the outer surface of the tubular cleaner support (520).

[0140] In this case, the filter cleaner (510) may be formed as a ring structure that wraps around the outer surface of the cleaner support (520).

[0141] In order for the filter cleaner (510) to evenly sweep the inner surface of the pre-filter section (400), it is necessary for the filter cleaner (510) to be uniformly arranged along the inner cross-section of the pre-filter section (400). To this end, it may be preferable for the filter cleaner (510) to be arranged in a ring shape along the inner surface of the pre-filter section (400).

[0142] In this case, in order to uniformly support the ring-shaped filter cleaner (510), the cleaner support body (520) needs to be formed as a rod-shaped or tubular structure having an outer diameter corresponding to the inner diameter of the filter cleaner (510).

[0143] However, since it may be difficult to lighten the cleaning device (1000) when the cleaning device support body (520) is formed in a rod-shaped structure, the relative weight increases, so it may be preferable to form the cleaning device support body (520) in a tubular structure.

[0144] In this way, in the vacuum cleaner (1000) according to one embodiment of the present invention, the vacuum cleaner support body (520) is formed in a tubular shape that penetrates along the longitudinal direction, so the vacuum cleaner support body (520) can be made lighter while the filter cleaner (510) can be smoothly supported.

[0145] In a vacuum cleaner (1000) according to one embodiment of the present invention, a plurality of through holes (521) may be formed along the circumference of the vacuum cleaner support (520). That is, as shown in FIG. 8a and FIG. 9a, a plurality of through holes (521) may be formed on the circumference of the vacuum cleaner support (520) which is formed as a tubular structure.

[0146] Accordingly, air can flow in and out of the cleaning support body (520) through the through hole (521) on the periphery surface.

[0147] In particular, as described above, when the suction airflow is formed from the inside to the outside of the pre-filter section (400), the air inside the cleaner support body (520) is discharged to the outside through the through hole (521) and can then pass through the inner surface of the pre-filter section (400) and be discharged to the outside of the pre-filter section (400).

[0148] In this case, since a plurality of through holes (521) can be evenly formed on the circumferential surface of the cleaner support (520), the air inside the cleaner support (520) can be evenly dispersed and flow across the entire circumferential surface of the cleaner support (520).

[0149] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a plurality of through holes (521) formed along the circumference of the vacuum cleaner support body (520), so that a flow guide function that more uniformly disperses the air flowing into the interior of the vacuum cleaner support body (520) can be achieved to some extent.

[0150] FIGS. 10 and 11 are drawings showing the process of a pre-filter part (400) being coupled to a main body (100) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 12 is a drawing showing the coupling surface of the main body (100) to which the pre-filter part (400) is coupled in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 13 is a drawing showing the coupling surface of the pre-filter part (400) coupled to the main body (100) in a vacuum cleaner (1000) according to an embodiment of the present invention.

[0151] In a vacuum cleaner (1000) according to one embodiment of the present invention, the filter cleaning unit (500) may further include a filter cleaning shaft (540) that is installed along the longitudinal direction and is connected to one side of a filter cleaner (510) and moves up and down together with the filter cleaner (510).

[0152] That is, the filter cleaner (510) can be positioned on the inner surface of the pre-filter section (400) with one side connected to the filter cleaning shaft (540). And, when the filter cleaning shaft (540) moves up and down along the longitudinal direction, the filter cleaner (510) connected to the filter cleaning shaft (540) moves up and down together and can sweep down the inner surface of the pre-filter section (400).

[0153] In this case, a cleaning shaft connector (541) is formed on one side of the filter cleaner (510), and the end of the filter cleaning shaft (540) can be connected to the cleaning shaft connector (541).

[0154] In particular, the filter cleaning shaft (540) is connected to the dust cleaning unit (700) described later or is connected independently to the cleaning lever (730), so that the user can easily raise and lower the filter cleaner (510) by moving the cleaning lever (730) located outside the cleaner (1000) along the longitudinal direction.

[0155] In this way, in the vacuum cleaner (1000) according to one embodiment of the present invention, one side of the filter cleaner (510) is coupled to the filter cleaning shaft (540) installed along the longitudinal direction and is raised together, so the structure for the installation and raising of the filter cleaner (510) can be made simpler.

[0156] In a vacuum cleaner (1000) according to one embodiment of the present invention, the pre-filter part (400) may have an insertion groove (401) formed along the longitudinal direction into which a filter cleaning shaft (540) can be inserted.

[0157] As described above, the inner surface of the pre-filter section (400) must be positioned to be in contact with the filter cleaner (510), and since one side of the filter cleaner (510) must be coupled to the filter cleaning shaft (540), the pre-filter (410) of the pre-filter section (400) must not be positioned in the part of the filter cleaner (510) where the filter cleaning shaft (540) is positioned, and must be formed as an empty space.

[0158] Accordingly, as shown in FIGS. 12 and 13, an insertion groove (401) is formed along the longitudinal direction in a part of the pre-filter section (400), and the pre-filter section (400) can be formed in a structure in which the filter cleaning shaft (540) is placed in the insertion groove (401) and the pre-filter section (400) is coupled to the main body (100).

[0159] In this case, the cleaning shaft connector (541) coupled to the end of the filter cleaning shaft (540) can also be placed in the insertion groove (401) together with the filter cleaning shaft (540).

[0160] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a filter cleaning shaft (540) inserted into an insertion groove (401) formed in a pre-filter part (400), so that when the pre-filter part (400) is coupled to the main body (100), the filter cleaning shaft (540) can be prevented from interfering with the pre-filter part (400).

[0161] In a vacuum cleaner (1000) according to one embodiment of the present invention, a pre-filter part (400) can be inserted into a main body (100) and then rotated and coupled.

[0162] That is, the process of combining the pre-filter section (400) and the main body (100) can first be performed by inserting the pre-filter section (400) into the upper surface of the main body (100) from the top downward, as shown in FIG. 10. In this case, the pre-filter section (400) can be inserted in a state where the filter cleaning shaft (540) is positioned in the insertion groove (401) of the pre-filter section (400).

[0163] Next, as illustrated in FIG. 11, the pre-filter part (400) inserted into the main body (100) can be rotated in one direction to enable the pre-filter part (400) and the main body (100) to be connected. In this case, a separate groove and a protrusion structure may be formed on the connection surface between the pre-filter part (400) and the main body (100).

[0164] Meanwhile, the process of separating the pre-filter section (400) from the main body (100) can be carried out by performing the above process in reverse order.

[0165] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention can be structured so that the connection and separation of the pre-filter part (400) and the main body (100) are made easier, as the pre-filter part (400) is inserted into the main body (100) and then rotated to connect the main body (100) and the pre-filter part (400) when the main body (100) and the pre-filter part (400) are connected.

[0166] In a vacuum cleaner (1000) according to one embodiment of the present invention, the spacing (D) of the insertion groove (401) may be formed to be greater than the rotational distance (L) of the pre-filter part (400).

[0167] As described above, the pre-filter part (400) is inserted into the main body (100) in a state where the filter cleaning shaft (540) is positioned in the insertion groove (401) of the pre-filter part (400), and in this state, the pre-filter part (400) is rotated to connect the pre-filter part (400) and the main body (100). Therefore, the filter cleaning shaft (540) must be able to remain positioned within the insertion groove (401) even when the pre-filter part (400) is rotated.

[0168] Accordingly, as shown in FIGS. 11 and 13, the gap (D) of the insertion groove (401) is formed such that it is greater than the rotation distance (L) of the pre-filter section (400), so that the filter cleaning shaft (540) can still be positioned within the insertion groove (401) even when the pre-filter section (400) is rotated.

[0169] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a gap (D) of the insertion groove (401) formed such that it is greater than the rotation distance (L) of the pre-filter part (400) that is inserted into the main body (100) and rotated, thereby preventing the filter cleaning shaft (540) from interfering with the pre-filter part (400) when the pre-filter part (400) inserted into the main body (100) is rotated.

[0170] In a vacuum cleaner (1000) according to one embodiment of the present invention, a vacuum cleaner cover (530) can be fitted and coupled around the upper surface of a vacuum cleaner support (520).

[0171] That is, as shown in FIG. 9a, the inner diameter of the cleaner cover (530) is formed to a size corresponding to the outer diameter of the upper surface of the cleaner support (520), so that the inner surface of the cleaner cover (530) can be joined to the outer surface of the upper surface of the cleaner support (520).

[0172] In addition, the cleaner cover (530) can cover the upper surface of the filter cleaner (510) by a portion that protrudes outward from the part joined to interlock with the cleaner support (520).

[0173] In this way, in the vacuum cleaner (1000) according to one embodiment of the present invention, the vacuum cleaner cover (530) is fitted and coupled to the upper surface of the vacuum cleaner support (520), so that the coupling between the vacuum cleaner support (520) and the vacuum cleaner cover (530) can be uniformly formed.

[0174] In a vacuum cleaner (1000) according to one embodiment of the present invention, a vacuum cleaner support (520) may have a coupling groove (522) formed on its upper surface in a closed shape. In this case, a vacuum cleaner cover (530) may have a coupling projection (532) formed thereon that is inserted into the coupling groove (522).

[0175] That is, as illustrated in FIG. 9a, the cleaner support (520) may be formed with a shape in which the upper surface is closed and the lower surface is open. Accordingly, air flowing into the interior of the cleaner support (520) through the cyclone section (300) can be guided to the inner surface of the pre-filter section (400) through the through hole (521) on the circumference of the cleaner support (520).

[0176] The cleaning support body (520) may have a coupling groove (522) formed on its closed upper surface for coupling with the cleaning cover (530).

[0177] Accordingly, the cleaner cover (530) coupled to the upper surface of the cleaner support body (520) has a coupling projection (532) formed thereon, so that when coupled with the cleaner support body (520), the coupling projection (532) can be inserted into the coupling groove (522).

[0178] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention is coupled such that the coupling projection (532) of the vacuum cleaner cover (530) is inserted into the coupling groove (522) of the vacuum cleaner support (520), thereby allowing the coupling between the vacuum cleaner support (520) and the vacuum cleaner cover (530) to be more stably formed.

[0179] In a vacuum cleaner (1000) according to one embodiment of the present invention, the filter cleaner (510) may include a filter cleaning frame (511) and a filter cleaning body (512).

[0180] The filter cleaning frame (511) is a part arranged along the inner cross-section of the pre-filter section (400) and may be a part where the filter cleaning body (512) is installed and supported. In this case, the filter cleaning frame (511) may be made of a material having a certain rigidity so that deformation or damage is minimized during lifting.

[0181] The filter cleaning body (512) is made of an elastic material and is formed to protrude from the outer surface of the filter cleaning frame (511) and is a part that comes into contact with the inner surface of the pre-filter part (400), and may be a part that comes into physical contact to sweep down the inner surface of the pre-filter part (400).

[0182] Although it is necessary to apply a certain physical force to remove dust collected on the inner surface of the pre-filter section (400) using such a filter cleaning body (512), if it is formed from an excessively hard material, there is a risk that the filter cleaning body (512) in contact with the inner surface of the pre-filter section (400) will be damaged during lifting.

[0183] Accordingly, the filter cleaning body (512) is made of an elastic material separate from the filter cleaning frame (511) and can sweep down the inner surface of the pre-filter part (400) while minimizing damage during lifting.

[0184] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention can be structured more appropriately in terms of function because the filter cleaner (510) includes a filter cleaning frame (511) and a filter cleaning body (512), so the part for stable lifting and the part for dust removal are separated in the filter cleaner (510).

[0185] In a vacuum cleaner (1000) according to one embodiment of the present invention, the cleaner cover (530) may be formed in a shape that covers the upper surface of the filter cleaning frame (511).

[0186] As described above, the filter cleaning frame (511) is a part formed to have a certain degree of rigidity to ensure stable lifting and minimizing deformation of the filter cleaner (510), and deformation or damage caused by external force also needs to be minimized.

[0187] On the other hand, the filter cleaning body (512) is a part made of an elastic material, so the risk of deformation or damage due to external force is relatively low.

[0188] Therefore, the cleaner cover (530) that covers and protects the upper surface of the filter cleaner (510) can sufficiently prevent deformation or damage to the filter cleaner (510) even if it only covers the upper surface of the filter cleaning frame (511) without needing to cover the entire upper surface of the filter cleaner (510).

[0189] In particular, if the cleaner cover (530) is formed to protrude outwardly to cover the upper surface of the filter cleaner (512), there is a risk that foreign matter may get stuck between the filter cleaner (512) and the cleaner cover (530), thereby degrading the function of the cleaner (1000).

[0190] Therefore, it may be preferable for the cleaner cover (530) to be placed only on the upper surface of the filter cleaning frame (511) so as to more appropriately cover only the parts that need protection.

[0191] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a cleaner cover (530) formed in a shape that covers the upper surface of the filter cleaning frame (511), so that parts that are at risk of malfunction or damage due to external impact can be protected more appropriately.

[0192] FIG. 14 is a drawing showing the state in which a filter cleaning unit (500) and a dust cleaning unit (700) are connected in a vacuum cleaner (1000) according to one embodiment of the present invention.

[0193] A vacuum cleaner (1000) according to one embodiment of the present invention may further include a dust cleaning unit (700) that is raised and lowered between a dust container (110) and a cyclone unit (300) to remove dust stored in the dust container (110).

[0194] That is, the dust cleaner (700) can sweep away dust existing between the dust container (110) and the cyclone unit (300) during the lifting process. A brush composed of multiple bristle bristles may be placed on this dust cleaner (700).

[0195] Additionally, the dust cleaner (700) may be structured such that a dust cleaner (710) is coupled to a dust cleaner shaft (720) arranged in the longitudinal direction and moves up and down, and the dust cleaner (700) may move up and down through a cleaning lever (730) exposed to the outside of the cleaner (1000).

[0196] That is, when the user moves the cleaning lever (730), the dust cleaner (700) connected to the cleaning lever (730) moves and can remove dust.

[0197] Meanwhile, an elastic member is disposed in the dust cleaner (700) so that when the user moves the cleaning lever (730), a restoring force can be generated in the opposite direction to the direction in which the cleaning lever (730) was moved.

[0198] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a dust cleaner (700) that moves up and down between the dust container (110) and the cyclone unit (300) to remove dust stored in the dust container (110), so that dust removal from the dust container (110) can be easily achieved through the movement of the dust cleaner (700).

[0199] In a vacuum cleaner (1000) according to one embodiment of the present invention, a filter cleaning unit (500) and a dust cleaning unit (700) are connected and can be raised together.

[0200] That is, as shown in FIG. 14, when the user moves the cleaning lever (730), not only the dust cleaner (700) but also the filter cleaning shaft (540) and filter cleaner (510) connected thereto can be moved together.

[0201] Accordingly, when the user moves the cleaning lever (730), dust removal from the dust bin (110) by the dust cleaner (700) and dust removal from the pre-filter unit (400) by the filter cleaner (510) can be performed simultaneously.

[0202] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention is connected so that the filter cleaning unit (500) is raised together with the dust cleaning unit (700), so that dust removal from the pre-filter unit (400) and the dust bin (110) is performed together through a single operation by the user, thereby improving the convenience of use.

[0203] A vacuum cleaner (1000) according to one embodiment of the present invention includes a main body (100), a suction unit (200), a cyclone unit (300), a suction motor unit (600), a pre-filter unit (400), and a filter cleaning unit (500). In this case, the filter cleaning unit (500) includes a filter cleaner (510).

[0204] The suction motor unit (600) is a part that generates a suction airflow so that air is sucked in through the suction unit (200), and when the suction motor unit (600) is operated, an airflow may be generated in which air moves in the order of the suction unit (200), dust bin (110), cyclone unit (300), pre-filter unit (400), and air outlet (120).

[0205] The pre-filter section (400) is installed between the cyclone section (300) and the suction motor section (600) and is a part where air moves from inside to outside and dust is filtered, and can filter dust in the air that was not separated in the cyclone section (300).

[0206] In particular, as shown in FIG. 2a, when the suction motor unit (600) is operated, the suction airflow can be introduced into the interior of the pre-filter unit (400) through the bottom and then pass through the pre-filter (410) arranged along the circumference and be discharged to the outside of the pre-filter unit (400).

[0207] Accordingly, since dust can be concentrated on the inner surface of the pre-filter section (400), it is necessary to frequently remove the dust collected on the inner surface of the pre-filter section (400) while using the vacuum cleaner (1000).

[0208] In relation to the structure of a filter cleaning unit (500) for removing dust collected on the inner surface of such a pre-filter unit (400), a filter cleaning member (510) is positioned along the inner cross-section of the pre-filter unit (400), contacts the inner surface of the pre-filter unit (400), and moves up and down to remove dust collected on the inner surface of the pre-filter unit (400).

[0209] That is, the filter cleaner (510) is raised and lowered while in physical contact with the inner surface of the pre-filter section (400), and can remove dust collected on the inner surface of the pre-filter section (400).

[0210] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention collects dust on the inner surface of a pre-filter section (400) where air moves from inside to outside and dust is filtered, and the filter cleaner (510) moves up and down to remove the collected dust from the inner surface of the pre-filter section (400), thereby allowing dust to be removed more directly and effectively from the pre-filter section (400) which is structured to collect dust on the inner surface.

[0211] In a vacuum cleaner (1000) according to one embodiment of the present invention, the filter cleaning unit (500) may further include a cleaning member support body (520) formed to have an outer diameter corresponding to the inner diameter of the filter cleaning member (510) and supporting the filter cleaning member (510) that is raised and lowered on the outer surface.

[0212] That is, the filter cleaner (510) can be raised and lowered to sweep down the inner surface of the pre-filter section (400) while the filter cleaner (510) is supported on the outer surface of the cleaner support body (520).

[0213] Accordingly, dust removal from the pre-filter section (400) is stably achieved through the lifting and lowering of the filter cleaner (510), so that the suction performance for cleaning can always be maintained in an appropriate state.

[0214] FIG. 15 is a perspective view showing a vacuum cleaner system (1) according to one embodiment of the present invention. FIG. 16 is a diagram schematically showing the main configuration of the vacuum cleaner system (1) shown in FIG. 15.

[0215] A vacuum cleaner system (1) according to one embodiment of the present invention includes a vacuum cleaner (1000) and a vacuum cleaner station (10).

[0216] The vacuum cleaner (1000) is a part that sucks in external air containing dust and separates dust from the air, and includes a main body (100), a suction part (200), a cyclone part (300), a suction motor part (600), a pre-filter part (400), and a filter cleaning part (500).

[0217] A vacuum cleaner station (10) is coupled to a vacuum cleaner (1000) to remove dust inside the vacuum cleaner (1000). This vacuum cleaner station (10) includes a housing (1100) in which a coupling part (1110) to which the vacuum cleaner (1000) is coupled is positioned, a dust collection part (1200) for collecting dust inside the vacuum cleaner (1000), a flow path part (1300) connecting the coupling part (1110) and the dust collection part (1200), and a dust suction module (1400) that generates a suction airflow so that dust inside the vacuum cleaner (1000) is sucked into the dust collection part (1200) through the flow path part (1300).

[0218] Specifically, a vacuum cleaner (1000) may be placed in the vacuum cleaner station (10). A vacuum cleaner (1000) may be attached to one side of the vacuum cleaner station (10). In particular, the main body of the vacuum cleaner (1000) may be attached to one side of the vacuum cleaner station (10). The vacuum cleaner station (10) can remove dust from the dust bin (110) of the vacuum cleaner (1000).

[0219] The vacuum cleaner station (10) may include a housing (1100). The housing (1100) may form the exterior of the vacuum cleaner station (10). Specifically, the housing (1100) may be formed in the shape of a column including at least one outer wall surface. As an example, the housing (1100) may be formed in a shape similar to a square column.

[0220] The housing (1100) may have a space formed to accommodate a dust collection unit (1200) that stores dust inside and a dust suction module (1400) that generates a flow force for dust to be collected by the dust collection unit (1200).

[0221] The housing (1100) may include a bottom surface, an outer wall surface, and a top surface. In this case, the outer wall surface may be configured to include at least one surface. For example, the outer wall surface may include a first outer wall surface, a second outer wall surface, a third outer wall surface, and a fourth outer wall surface.

[0222] At this time, in this embodiment, the first outer wall surface may be positioned on the front of the vacuum cleaner station (10). Here, "front" may refer to the surface where the vacuum cleaner (1000) is exposed when the vacuum cleaner (1000) is coupled to the vacuum cleaner station (10). Accordingly, the first outer wall surface may form the exterior of the front of the vacuum cleaner station (10).

[0223] The first outer wall surface may have an appearance corresponding to the shape of the vacuum cleaner (1000). Specifically, a connecting part (1110) may be disposed on the first outer wall surface. With this configuration, the vacuum cleaner (1000) can be connected to the vacuum cleaner station (10) and supported by the vacuum cleaner station (10).

[0224] The coupling portion (1110) is disposed on the first outer wall surface, and the main body (100) of the vacuum cleaner (1000), the dust bin (110), and the battery (140) can be coupled. The coupling portion (1110) may include a coupling surface. The coupling surface may be disposed on the side of the housing (1100). For example, the coupling surface may refer to a surface formed in a concave groove shape facing the inside of the vacuum cleaner station (10) from the first outer wall surface. That is, the coupling surface may refer to a surface formed in a step with the first outer wall surface.

[0225] A vacuum cleaner (1000) can be attached to the attachment surface. For example, the attachment surface may come into contact with the lower side of the dust bin (110) and battery (140) of the vacuum cleaner (1000). Here, the lower side may refer to the surface facing the ground when the user uses the vacuum cleaner (1000) or places it on the ground.

[0226] A dust passage hole may be formed on the joint surface to allow air from outside the housing (1100) to flow into the interior. The dust passage hole may be formed in a hole shape corresponding to the shape of the dust container (110) so that dust from the dust container (110) flows into the dust collection unit (1200). The dust passage hole may be formed corresponding to the shape of the discharge cover of the dust container (110). The dust passage hole may be formed to communicate with the flow path unit (1300) to be described later.

[0227] With the vacuum cleaner (1000) connected to the vacuum cleaner station (10), the discharge cover is opened through a separate cover opening unit, etc., allowing dust inside the vacuum cleaner (1000) to be moved to the vacuum cleaner station (10).

[0228] The vacuum cleaner station (10) may include a dust collection unit (1200). The dust collection unit (1200) may be placed inside the housing (1100). The dust collection unit (1200) may be placed on the lower side in the direction of gravity of the coupling unit (1110).

[0229] The dust collector (1200) can be detachably coupled to the housing (1100). Thus, the dust collector (1200) can be separated from the housing (1100) and discarded, and a new dust collector (1200) can be coupled to the housing (1100). That is, the dust collector (1200) can be defined as a consumable part.

[0230] The vacuum cleaner station (10) may include a flow path (1300). The flow path (1300) may connect the dust bin (110) and the dust collection unit (1200) of the vacuum cleaner (1000). The flow path (1300) may be positioned at the rear side of the coupling surface. The flow path (1300) may refer to the space between the coupling unit (1110) to which the vacuum cleaner (1000) is coupled and the dust collection unit (1200). The flow path (1300) may be a space formed at the rear side from the dust bin hole, and may be a flow path formed by bending downward from the dust bin hole so that dust and air can flow.

[0231] The vacuum cleaner station (10) may include a dust suction module (1400). The dust suction module (1400) can generate a suction airflow so that dust inside the vacuum cleaner (1000) is sucked into the dust collection unit (1200) through the airflow path (1300).

[0232] The suction airflow generated by the dust suction module (1400) is transmitted into the dust container (110) through the dust collection unit (1200) along the flow path (1300) and the dust passage hole, and the dust inside the dust container (110) is discharged from the dust container (110) to the dust passage hole according to the flow of the suction airflow and then collected in the dust collection unit (1200) through the flow path (1300).

[0233] In the case of the vacuum cleaner station (10) as described above, not only can dust inside the dust bin (110) be sucked in and collected, but dust removed and detached from the pre-filter unit (400) by the filter cleaning unit (500) can also be sucked in and collected.

[0234] If the dust collected in the pre-filter unit (400) is simply removed through the filter cleaning unit (500), there is a risk that the removed dust may be re-collected in the pre-filter unit (400) during the process of scattering.

[0235] Accordingly, the vacuum cleaner system (1) according to the present embodiment can prevent dust from being re-collected in the pre-filter unit (400) by collecting dust removed from the pre-filter unit (400) through the vacuum cleaner station (10).

[0236] In this way, the vacuum cleaner system (1) according to one embodiment of the present invention has a vacuum cleaner station (10) that sucks up and collects dust removed from the inner surface of the pre-filter unit (400) by the filter cleaning unit (500), thereby preventing dust that has escaped from the pre-filter unit (400) from being re-collected in the pre-filter unit (400), so that the pre-filter unit (400) and the vacuum cleaner (1000) including it can maintain a state suitable for performing their original functions.

[0237] In a vacuum cleaner system (1) according to one embodiment of the present invention, a pre-filter section (400) is positioned above a cyclone section (300), and a pre-filter inlet (402) may be formed between the cyclone section (300) and the pre-filter section (400) through which air passing through the cyclone section (300) flows into the pre-filter section (400). In this case, the inner diameter (d1) of the pre-filter section (400) may be formed to be greater than or equal to the inner diameter (d2) of the pre-filter inlet (402).

[0238] That is, as illustrated in FIG. 2a and FIG. 4a, air passing through the cyclone section (300) moves upward and can be introduced into the pre-filter section (400) located at the top through the pre-filter inlet (402). Then, air moves from the inside to the outside of the pre-filter section (400), and dust can be collected on the inner surface of the pre-filter section (400).

[0239] In this case, since the inner diameter (d1) of the pre-filter section (400) is formed to be greater than the inner diameter (d2) of the pre-filter inlet (402), all air moving through the pre-filter inlet (402) flows into the interior of the pre-filter section (400), so that dust in the air can be filtered without any loss.

[0240] In this way, the vacuum cleaner system (1) according to one embodiment of the present invention is configured such that the inner diameter (d1) of the pre-filter section (400) is larger than or equal to the inner diameter (d2) of the pre-filter inlet (402), so that dust can be properly filtered from the air flowing into the pre-filter section (400) through the pre-filter inlet (402).

[0241] In a vacuum cleaner system (1) according to one embodiment of the present invention, the inner diameter (d2) of the pre-filter inlet (402) may be formed larger than the outer diameter (d3) of the filter cleaning frame (511).

[0242] As described above, when dust is collected on the inner surface of the pre-filter section (400), such dust can be removed from the inner surface of the pre-filter section (400) by the lifting of the filter cleaning section (500). In particular, dust removed from the inner surface of the pre-filter section (400) can naturally fall due to gravity.

[0243] In this case, since the inner diameter (d2) of the pre-filter inlet (402) is formed to be larger than the outer diameter (d3) of the filter cleaning frame (511), dust that falls off and detaches from the inner surface of the pre-filter part (400) can settle in the path near the pre-filter inlet (402) or below it.

[0244] Therefore, even if some of the dust removed from the pre-filter section (400) is scattered, it can be prevented from being re-collected in the pre-filter section (400). In particular, when dust is sucked and collected through the vacuum cleaner station (10), dust settled near the pre-filter inlet (402) or in the path below it can be smoothly moved to the vacuum cleaner station (10).

[0245] In this way, the vacuum cleaner system (1) according to one embodiment of the present invention is configured such that the inner diameter (d2) of the pre-filter inlet (402) is larger than the outer diameter (d3) of the filter cleaning frame (511), thereby minimizing dust that is removed from the pre-filter unit (400) by the filter cleaning unit (500) settling in the path near or below the pre-filter inlet (402) and being re-collected in the pre-filter unit (400).

[0246] In a vacuum cleaner system (1) according to one embodiment of the present invention, the outer diameter (d4) of the filter cleaning body (512) may be formed to be greater than or equal to the inner diameter (d1) of the pre-filter part (400).

[0247] Dust removal from the inner surface of the pre-filter section (400) through the filter cleaning section (500) can be achieved by the pressure exerted when the filter cleaner comes into contact with the outer surface of the pre-filter section (400). Therefore, it may be desirable for the entire outer diameter of the filter cleaner to be formed to be greater than the inner diameter of the pre-filter section (400) to increase the adhesion force between the filter cleaner and the inner surface of the pre-filter section (400).

[0248] However, as described above, since it is desirable that the outer diameter (d3) of the filter cleaning frame (511) is not larger than the inner diameter (d2) of the pre-filter inlet (402), it may be desirable to minimize the filter cleaning frame (511) while maximizing the outer diameter (d4) of the filter cleaning body (512).

[0249] In this way, the vacuum cleaner system (1) according to one embodiment of the present invention is configured such that the outer diameter (d4) of the filter cleaning body (512) is larger than or equal to the inner diameter (d1) of the pre-filter section (400), thereby increasing the adhesion force of the filter cleaning body (512) to the inner surface of the pre-filter section (400) and improving the dust removal efficiency.

[0259] In addition, according to at least one embodiment of the present invention, the gap of the insertion groove is formed to be greater than the rotational distance of the pre-filter part that is rotated after being inserted into the main body, so that the filter cleaning shaft can be prevented from interfering with the pre-filter part when the pre-filter part inserted into the main body is rotated.

[0260] In addition, according to at least one of the embodiments of the present invention, a cleaner cover is fitted around the upper surface of a cleaner support, so that the connection between the cleaner support and the cleaner cover can be uniformly formed.

[0261] In addition, according to at least one of the embodiments of the present invention, the coupling projection of the cleaner cover is inserted into the coupling groove of the cleaner support and coupled, so the coupling between the cleaner support and the cleaner cover can be achieved more stably.

[0262] In addition, according to at least one embodiment of the present invention, since the filter cleaner includes a filter cleaning frame and a filter cleaning body, the part for stable lifting and the part for dust removal are separated in the filter cleaner, so that it can be formed into a structure that is more suitable in terms of function.

[0263] In addition, according to at least one embodiment of the present invention, since the cleaner cover is formed in a shape that covers the upper surface of the filter cleaning frame, parts that are at risk of malfunction or damage due to external impact can be more appropriately protected.

[0264] In addition, according to at least one embodiment of the present invention, the dust cleaner is raised and lowered between the dust bin and the cyclone unit and removes dust stored in the dust bin, so that dust removal from the dust bin can be easily achieved through the raising and lowering of the dust cleaner.

[0266] In addition, according to at least one embodiment of the present invention, dust is collected on the inner surface of a pre-filter section in which air moves from the inside to the outside and dust is filtered, and the collected dust is removed from the inner surface of the pre-filter section by a filter cleaner that moves up and down, thereby allowing dust to be removed more directly and effectively from the pre-filter section formed with a structure in which dust is collected on the inner surface.

[0267] In addition, according to at least one embodiment of the present invention, the vacuum cleaner station sucks in and collects dust removed from the inner surface of the pre-filter unit by the filter cleaning unit, thereby preventing dust detached from the pre-filter unit from being re-collected in the pre-filter unit, so that the pre-filter unit and the vacuum cleaner including it can be maintained in a state suitable for performing their inherent functions.

[0270] In addition, according to at least one embodiment of the present invention, the outer diameter of the filter cleaning body is made larger than or equal to the inner diameter of the pre-filter part, so that the adhesion force of the filter cleaning body to the inner surface of the pre-filter part is increased, thereby improving dust removal efficiency.
