Description

vacuum cleaner

[0001] The present invention relates to a vacuum cleaner, and more specifically, to a vacuum cleaner capable of performing 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 while the user moves the vacuum cleaner directly, and automatic vacuum cleaners, which are used for cleaning while 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 increasingly 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, Korean Registered Patent No. 10-2676424 (hereinafter referred to as the 'prior art') discloses a vacuum cleaner.

[0009] Specifically, the invention discloses a housing having an intake opening, a cyclone section for separating air and dust, and a dust bin for storing dust separated from air in the cyclone section; a guide wall arranged within the housing to surround the axis of the cyclone flow of the cyclone section and to guide the flow of air; and 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.

[0010] However, the vacuum cleaner of the prior art discloses a configuration in which air sucked in from the suction opening is guided through a guide channel formed by a guide wall and a frame, but there is a problem in that the cleaning performance is difficult to achieve smoothly because there is a narrow section in this guide channel and it is formed with a shape and structure that is prone to being blocked by foreign matter of a certain size or larger.

[0011] As described above, a vacuum cleaner that performs cleaning by drawing in external air and separating dust from the air faces a challenge that must be addressed to ensure the smooth flow of the drawn-in air so that cleaning performance can always be maintained at an appropriate level.

[0012] However, conventional vacuum cleaners have limitations in that they cannot adequately solve these problems.

[0013] 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.

[0014] Specifically, the present invention aims to provide a vacuum cleaner in which the structure guiding the movement of inhaled air is configured to minimize blockage by foreign substances, thereby ensuring that the suction performance for cleaning is always properly maintained during use.

[0015] In addition, the present invention aims to provide a vacuum cleaner in which air movement to each component can be smoothly facilitated by ensuring that the structure guiding the movement of the sucked air is configured to form an appropriate flow path direction within the vacuum cleaner.

[0016] In addition, the present invention aims to provide a vacuum cleaner in which a structure guiding the movement of inhaled air is configured to minimize flow resistance, thereby enabling a smooth suction airflow to be formed even with relatively low suction force.

[0017]

[0018] 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.

[0019] To achieve the above or other purposes, a vacuum cleaner according to one aspect of the present invention is configured such that a guide channel connected to an air intake path through a suction part is structured to minimize blockage by foreign matter. Specifically, a guide fence is spaced apart from the outer side of a guide wall, and a guide cover connects the upper ends of each of the guide wall and the guide fence to form a guide channel, thereby minimizing the narrow section between the guide wall and the guide fence.

[0020] 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.

[0021] In addition, a vacuum cleaner according to one aspect of the present invention is configured such that a guide channel connected to an air intake path through a suction part is structured to form a cyclone flow. Specifically, a guide blade is installed at the part where the guide channel is connected to the suction part, thereby forming an air flow direction toward one side along the circumference of the guide wall.

[0022] In addition, a vacuum cleaner according to one aspect of the present invention is configured such that a guide channel connected to the air intake path through the intake section is structured to minimize flow resistance. Specifically, the blade inclination of the guide blade is formed to be inclined toward one side in the circumferential direction of the guide wall to minimize flow resistance of the intake air.

[0023] In addition, in a vacuum cleaner according to one aspect of the present invention, the upper portion of a blade inclined body formed to be bent is coupled to a guide wall, and the remaining portion may be spaced apart from the guide wall.

[0024] In addition, in a vacuum cleaner according to one aspect of the present invention, the blade parallel of the guide blade may be formed parallel to the inner surface of the dust bin.

[0025] In addition, a vacuum cleaner according to one aspect of the present invention may have a suction blade installed in the suction part along a virtual extension line that is continuous with a guide blade, thereby forming an air flow path direction together with the guide blade.

[0026] In addition, in a vacuum cleaner according to one aspect of the present invention, a guide fence may be formed relatively small at the inlet portion of the guide channel in the direction of air movement along the guide channel.

[0027] In addition, in a vacuum cleaner according to one aspect of the present invention, a guide cover may be formed relatively high at the inlet portion of the guide channel in the direction of air movement along the guide channel.

[0028] In addition, a cleaning ring may be attached to the bottom of a guide wall in a cleaning device according to one aspect of the present invention.

[0029] In addition, according to one aspect of the present invention, the cleaning ring may be formed with a shape in which the outer diameter decreases toward the bottom.

[0030] In addition, a vacuum cleaner according to one aspect of the present invention may perform cleaning using an elastic material.

[0031] In addition, in a vacuum cleaner according to one aspect of the present invention, the lowest ends of the cleaning ring and the guide blade, respectively, may be positioned at the same height.

[0032] In addition, according to one aspect of the present invention, a cleaning device may have one side of a dust cleaning unit coupled to a dust cleaning shaft installed along the longitudinal direction and be raised and lowered together.

[0033] In addition, a vacuum cleaner according to one aspect of the present invention may be connected such that a filter cleaner, which removes dust collected in a pre-filter section, is raised together with a dust cleaner.

[0034]

[0035] The means for solving the technical problems to be achieved in the present invention are not limited to the means mentioned above, and other means not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0049]

[0050] FIG. 1 is a perspective view showing a vacuum cleaner (1000) according to one embodiment of the present invention. FIG. 2 is a cross-sectional view showing a vacuum cleaner (1000) according to one embodiment of the present invention.

[0051] Referring to FIGS. 1 and FIGS. 2, a vacuum cleaner (1000) according to one embodiment of the present invention is schematically described as follows.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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).

[0056] 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.

[0057] 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).

[0058] 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.

[0059] 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).

[0060] 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).

[0061] The cyclone flow generated in the first cyclone section may be due to the suction force of the suction motor section (600).

[0062] 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.

[0063] 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.

[0064] 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).

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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).

[0070] 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).

[0071] 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).

[0072] 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).

[0073] 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).

[0074] 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).

[0075] The dustbin (110) may include a discharge cover. The discharge cover may be placed on the lower side of the dustbin (110).

[0076] 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.

[0077] 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).

[0078] By doing so, when the user holds the handle (130) and cleans, it is possible to prevent strain on the user's wrist.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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).

[0084] 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).

[0085] FIG. 3 is a drawing showing a state in which a part of the main body (100) is omitted in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 4 and FIG. 5 are drawings showing a part of a guide channel (Fg) connected to a suction part (200) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 6 is a drawing showing the air suction path through the suction part (200) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 7 is a drawing showing the air movement path through the guide channel (Fg) in a vacuum cleaner (1000) according to an embodiment of the present invention.

[0086] In this case, FIG. 4 is a view of a part of the guide channel (Fg) connected to the suction part (200) from the outside of the vacuum cleaner (1000), and FIG. 5 is a view of a part of the guide channel (Fg) connected to the suction part (200) from the inside of the vacuum cleaner (1000).

[0087] 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), and a dust cleaning part (700). In this case, the dust cleaning part (700) includes a guide wall (701), a guide fence (702), and a guide cover (703).

[0088] 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.

[0089] 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.

[0090] 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).

[0091] 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.

[0092] The dust cleaner (700) is installed to surround the cyclone flow axis of the cyclone section (300), and at least a portion is connected to the air intake path through the intake section (200) to form a guide path (Fg) that guides the movement of the air being sucked in.

[0093] Here, the cyclone flow axis is a virtual axis that serves as the center of the cyclone flow generated in the cyclone section (300), and the air flowing in the cyclone section (300) can flow along a spiral path centered on the cyclone flow axis due to centrifugal force and gravitational settling.

[0094] That is, the dust cleaner (700) can be formed in a ring shape that surrounds the outer side of the cyclone section (300). A ring-shaped guide channel (Fg) is formed in this dust cleaner (700), and the inlet (E) of the guide channel (Fg) is connected to the air intake path through the intake section (200), so that the air intake through the intake section (200) can move along the guide channel (Fg).

[0095] Accordingly, air sucked in through the suction part (200) moves to the guide channel (Fg) through the inlet (E) of the guide channel (Fg), and the air moving along the guide channel (Fg) moves along a ring-shaped path to form a cyclone flow and can move to the cyclone part (300) and the dust container (110).

[0096] In relation to the structure of the dust cleaner (700) as described above, the guide wall (701) is a ring-shaped part arranged to surround the cyclone flow axis of the cyclone section (300) and can form the inner wall of the guide channel (Fg).

[0097] The guide fence (702) is spaced apart from the outer side of the guide wall (701) and extends along the inner surface of the dust container (110) to form a guide channel (Fg) together with the guide wall (701), and can form the outer wall of the guide channel (Fg).

[0098] The guide cover (703) is a part that covers the upper surface of the guide channel (Fg) by connecting the upper end of the guide wall (701) and the upper end of the guide fence (702), and can form the upper side wall of the guide channel (Fg).

[0099] Accordingly, air moved into the guide channel (Fg) through the inlet (E) of the guide channel (Fg) can move along a loop-shaped path in the space between the guide wall (701) and the guide fence (702). In this process, the air moving along the guide channel (Fg) is blocked from moving upward by the guide cover (703), and can move partially downward through the open path, allowing it to gradually move to the cyclone section (300) and the dust bin (110).

[0100] In particular, since the guide fence (702) is spaced apart from the outer side of the guide wall (701) and the guide fence (702) and the guide wall (701) are joined through the guide cover (703), the guide wall (701) and the guide fence (702) are not directly joined, so the narrow section between the guide wall (701) and the guide fence (702) can be minimized.

[0101] If the guide wall (701) and the guide fence (702) are directly connected in a section of the guide channel (Fg), there is a risk that foreign matter of a certain size or larger will accumulate in that section, as a relatively narrow valley structure is formed therein.

[0102] Therefore, it may be desirable to ensure that the guide wall (701) and the guide fence (702) forming the guide channel (Fg) are not directly connected so that the narrow section on the guide channel (Fg) is minimized.

[0103] In this way, a vacuum cleaner (1000) according to one embodiment of the present invention has a guide fence (702) spaced apart from the outer side of a guide wall (701), and a guide cover (703) connects the upper ends of each of the guide wall (701) and the guide fence (702) to form a guide channel (Fg), thereby minimizing the narrow section between the guide wall (701) and the guide fence (702), so that foreign substances of a certain size or larger can be sucked in smoothly, and the suction performance for cleaning can always be maintained in an appropriate state.

[0104] In a vacuum cleaner (1000) according to one embodiment of the present invention, a dust cleaning unit (700) can be raised and lowered between a dust container (110) and a cyclone unit (300) to remove dust stored in the dust container (110).

[0105] 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).

[0106] As described above, the dust cleaner (700) is positioned to surround the cyclone flow axis of the cyclone section (300), and in particular, the dust cleaner (700) can be positioned to surround the first filter section that filters dust of the cyclone section (300).

[0107] Accordingly, the dust cleaner (700) can sweep away dust collected in the first filter unit through lifting to prevent clogging of the first filter unit, and compress large volume dust inside the dust container (110) to ensure cleaning performance for a long time.

[0108] Additionally, the dust cleaner (700) may be structured such that one side is connected 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).

[0109] 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.

[0110] 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.

[0111] 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).

[0112] In a vacuum cleaner (1000) according to one embodiment of the present invention, the dust cleaning unit (700) may further include a guide blade (710) installed at the part where the guide channel (Fg) is connected to the suction unit (200) and shielding one side of the guide wall (701) in the perimeter direction.

[0113] That is, as illustrated in FIGS. 4 to 7, a guide blade (710) is installed at the inlet (E) of the guide channel (Fg) to shield one side of the guide wall (701) in the circumferential direction, thereby allowing the air in the guide channel (Fg) to move in one direction.

[0114] As described above, when air moves along the ring-shaped guide channel (Fg), a cyclone flow can be formed; however, when air is dispersed from the inlet (E) of the guide channel (Fg) to both sides in the circumferential direction of the guide wall (701), such a cyclone flow may not be smooth.

[0115] Therefore, it may be desirable to concentrate air on one side of the guide wall (701) in the circumferential direction from the inlet (E) of the guide channel (Fg) so that the cyclone flow is smoothly formed.

[0116] In this way, in a vacuum cleaner (1000) according to one embodiment of the present invention, a guide blade (710) is installed at the part where the guide channel (Fg) is connected to the suction part (200) to form an air channel direction on one side of the circumferential direction of the guide wall (701), so that air movement to form a cyclone flow can be smoothly achieved.

[0117] FIG. 8 is a perspective view showing a dust cleaner (700) in a vacuum cleaner (1000) according to an embodiment of the present invention. FIG. 9 is a drawing showing the dust cleaner (700) shown in FIG. 8 viewed from one direction. FIG. 10 is a drawing showing the dust cleaner (700) shown in FIG. 8 viewed from another direction. FIG. 11 is a drawing showing the dust cleaner (700) shown in FIG. 8 viewed from yet another direction.

[0118] In a vacuum cleaner (1000) according to one embodiment of the present invention, the guide blade (710) may include a blade inclined body (711) formed to be inclined toward one side in the circumferential direction of the guide wall (701).

[0119] When air introduced through the intake section (200) moves to the guide channel (Fg), the air may collide with the guide wall (701) at the inlet (E) of the guide channel (Fg). In this case, if the collision angle between the air and the guide wall (701) is close to vertical, flow resistance may occur in the air moving to the guide channel (Fg), and the movement of air along the guide channel (Fg) may not be smooth.

[0120] Therefore, it may be desirable to allow air to move along the blade inclined body (711) formed at an angle at the inlet (E) of the guide channel (Fg) and collide with the guide wall (701) at an angle, thereby lowering the flow resistance relatively and allowing the movement of air along the guide channel (Fg) to be smooth.

[0121] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a blade inclined body (711) of the guide blade (710) formed to be inclined toward one side in the circumferential direction of the guide wall (701), thereby minimizing the flow resistance of the sucked air, so that a suction airflow for cleaning can be smoothly formed even with a relatively small suction force.

[0122] In a vacuum cleaner (1000) according to one embodiment of the present invention, the blade inclined body (711) may be formed in a shape in which the upper part is connected to the guide wall (701) and the remaining part is spaced apart from the guide wall (701).

[0123] That is, as shown in FIGS. 10 and 11, a gap is formed between the blade inclined body (711) and the guide wall (701) through which air can move, and the blade inclined body (711) and the guide wall (701) can be connected and joined to each other in the upper part of this gap.

[0124] Accordingly, the air moving along the guide channel (Fg) can be moved along a ring-shaped path in one direction from the inlet (E) of the guide channel (Fg), and then moved back to the inlet (E) of the guide channel (Fg) through the gap between the blade inclined body (711) and the guide wall (701).

[0125] If the space between the blade inclined body (711) and the guide wall (701) is blocked without any separate gap, air moving along a ring-shaped path in one direction from the inlet (E) of the guide channel (Fg) may be blocked between the blade inclined body (711) and the guide wall (701), and flow resistance may occur so that it can no longer flow.

[0126] Therefore, it may be desirable to combine the blade inclined body (711) with the guide wall (701) while forming a gap between the blade inclined body (711) and the guide wall (701) through which air can move.

[0127] In this way, in a vacuum cleaner (1000) according to one embodiment of the present invention, the upper portion of the blade inclined body (711) formed to be bent is coupled to the guide wall (701) and the remaining portion is spaced apart from the guide wall (701), so the flow resistance of air circulating along the circumference of the guide wall (701) can be reduced.

[0128] In a vacuum cleaner (1000) according to one embodiment of the present invention, the guide blade (710) may further include a blade parallel member (712) formed parallel to the inner surface of the dust bin (110) on the outer side of the blade inclined member (711).

[0129] That is, the guide blade (710) includes a blade inclined body (711) in which the portion coupled to the guide wall (701) is formed at an angle, and may further include a blade parallel body (712) coupled to the outside from the blade inclined body (711). In particular, the blade parallel body (712) may be formed parallel to the inner surface of the dust container (110) and the inner surface of the guide wall (701).

[0130] As described above, the air moved to the inlet (E) of the guide channel (Fg) through the suction part (200) can be intensively guided in one direction by the guide blade (710), but some of the air may flow in the opposite direction.

[0131] In this case, foreign substances in the air flowing in the opposite direction may accumulate between the guide blade (710) and the dust bin (110), and consequently, there is a concern that the air movement along the guide path (Fg) may not be smooth.

[0132] Accordingly, it may be desirable to form a blade parallel body (712) on the outer side of the guide blade (710) that faces parallel to the inner surface of the dust container (110) so that foreign substances in the air do not accumulate between the guide blade (710) and the dust container (110) even if some of the air flows in the opposite direction.

[0133] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention can prevent foreign matter from accumulating between the inner surface of the dust container (110) and the guide blade (710) because the blade parallel member (712) of the guide blade (710) is formed parallel to the inner surface of the dust container (110).

[0134] In a vacuum cleaner (1000) according to one embodiment of the present invention, the suction part (200) may include a suction blade (210) that is continuously arranged along a virtual extension line with a guide blade (710) and shields one side of the suction part (200) on the air suction path.

[0135] That is, as illustrated in FIG. 6, a suction blade (210) is installed in the suction section (200) to shield one side of the air intake path through the suction section (200). Since the suction blade (210) is arranged continuously along a virtual extension line with the guide blade (710), the air whose direction of travel is guided by the suction blade (210) can naturally have its direction of travel guided by the guide blade (710).

[0136] Accordingly, the direction of travel of the air sucked in through the suction part (200) is guided by the suction blade (210) before it reaches the guide channel (Fg), and in conjunction with this, the air can be concentrated on one side of the guide wall (701) in the circumferential direction from the inlet (E) of the guide channel (Fg), so that the cyclone flow can be formed more smoothly.

[0137] In this way, a vacuum cleaner (1000) according to one embodiment of the present invention has a suction blade (210) that is continuous with a guide blade (710) installed in a suction section (200) along a virtual extension line, and forms an air flow path direction together with the guide blade (710), so that air can be moved from the suction section (200) in a direction to form a cyclone flow.

[0138] In a vacuum cleaner (1000) according to one embodiment of the present invention, the guide fence (702) may be formed such that the portion near the inlet (E) of the guide channel (Fg) is relatively small in the direction of air movement along the guide channel (Fg).

[0139] That is, as shown in FIGS. 7 to 11, the guide fence (702) is effectively omitted at the entrance (E) portion of the guide channel (Fg), and the size of the guide fence (702) gradually increases along the direction of air movement in the guide channel (Fg) to form the outer wall of the guide channel (Fg).

[0140] In that the air sucked in through the suction part (200) moves to the guide channel (Fg) through the inlet (E) of the guide channel (Fg), the guide fence (702) corresponding to the outer wall of the guide channel (Fg) does not need to be formed at the inlet (E) of the guide channel (Fg).

[0141] Rather, if a guide fence (702) is formed in large portions at the entrance (E) of the guide channel (Fg), there is a risk that the air sucked in through the suction part (200) will not be able to move to the guide channel (Fg) and will be blocked by the guide fence (702).

[0142] In addition, for air to move stably along the guide channel (Fg), a guide fence (702) corresponding to the outer wall of the guide channel (Fg) needs to be formed with a predetermined size in the part excluding the inlet (E) of the guide channel (Fg).

[0143] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention can form a larger air inlet area at the inlet (E) of the guide channel (Fg) because the guide fence (702) is formed relatively small in the direction of air movement along the guide channel (Fg).

[0144] In a vacuum cleaner (1000) according to one embodiment of the present invention, the guide cover (703) may be formed so that the part far from the inlet (E) of the guide channel (Fg) is relatively low in the direction of air movement along the guide channel (Fg).

[0145] That is, as shown in FIGS. 7 to 11, the height of the guide channel (Fg) can be gradually lowered along the direction of air movement in the guide channel (Fg).

[0146] As described above, since the air moving along the guide channel (Fg) forms a cyclone flow and must be moved to the cyclone section (300) and the dust container (110), the air passing through the guide channel (Fg) needs to gradually descend while moving along a ring-shaped path.

[0147] Therefore, it may be desirable to form the guide cover (703), which corresponds to the upper wall of the guide channel (Fg), so that it gradually decreases along the direction of air movement in the guide channel (Fg).

[0148] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention can induce the air circulating along the circumference of the guide wall (701) to move downward, because the guide cover (703) is formed relatively high in the inlet (E) portion of the guide channel (Fg) in the direction of air movement along the guide channel (Fg).

[0149] In a vacuum cleaner (1000) according to one embodiment of the present invention, the dust cleaning unit (700) may further include a ring-shaped cleaning ring (704) coupled to the bottom of a guide wall (701).

[0150] That is, a cleaning ring (704) with a corresponding shape is attached to the bottom of the ring-shaped guide wall (701), and this cleaning ring (704) protrudes downward from the guide channel (Fg) to participate in the removal and compression of dust.

[0151] As described above, since the guide wall (701) forms the inner wall of the guide channel (Fg), it may not be desirable for this guide wall (701) to directly remove or compress dust.

[0152] In addition, since the bottom surface of the guide wall (701) may not be formed evenly in some cases, there is a concern that dust between the dust container (110) and the cyclone unit (300) may not be shaken off and compressed evenly when the dust cleaner (700) is raised and lowered.

[0153] Accordingly, it may be desirable to attach a ring-shaped cleaning ring (704) integrally formed to the bottom of the guide wall (701) so that this cleaning ring (704) participates in the removal and compression of dust.

[0154] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention has a cleaning ring (704) attached to the bottom of the guide wall (701), so that during the lifting process of the dust cleaner (700), the dust between the dust container (110) and the cyclone unit (300) can be evenly shaken off and compressed by the cleaning ring (704).

[0155] In a vacuum cleaner (1000) according to one embodiment of the present invention, the cleaning ring (704) may be formed with a relatively smaller outer diameter as it extends downward. That is, the cleaning ring (704) may have a relatively larger distance from the inner surface of the dust container (110) as it extends downward.

[0156] As described above, when the dust cleaner (700) is raised and lowered to shake off and compress dust, if a large amount of dust exists inside the dust container (110), the raising and lowering of the dust cleaner (700) may not be smooth.

[0157] Accordingly, it may be desirable for the cleaning ring (704) to be formed with a tapered shape toward the bottom, and to have the lowest end formed relatively sharply, so that the dust cleaning unit (700) can be raised and lowered more smoothly even when a large amount of dust is present inside the dust container (110).

[0158] In this way, the cleaning device (1000) according to one embodiment of the present invention has a cleaning ring (704) formed in a shape in which the outer diameter becomes smaller towards the bottom, so that the compression of dust can be performed more smoothly during the downward movement of the dust cleaning unit (700).

[0159] In a vacuum cleaner (1000) according to one embodiment of the present invention, the cleaning ring (704) may be made of an elastic material.

[0160] As described above, the cleaning ring (704) is a part that shakes off and compresses dust when the dust cleaner (700) is raised and lowered, so it may be a part that comes into physical contact with the outer surface of the cyclone part (300) and the outer surface of the dust container (110).

[0161] This cleaning ring (704) needs to apply a certain physical force to shake off and compress dust between the cyclone section (300) and the dust bin (110), but if it is formed of an excessively hard material, there is a risk that the cleaning ring (704) will be damaged when physically contacting the outer surface of the cyclone section (300) and the outer surface of the dust bin (110) during lifting.

[0162] Accordingly, the cleaning ring (704) is made of an elastic material distinct from the other components of the dust cleaner (700), so that it can shake off and compress dust between the cyclone unit (300) and the dust container (110) while minimizing damage during lifting.

[0163] In this way, the cleaning device (1000) according to one embodiment of the present invention has a cleaning ring (704) made of an elastic material, so that the cleaning ring (704) can be prevented from being deformed or damaged by an external force during the lifting and lowering process of the dust cleaning unit (700).

[0164] In a vacuum cleaner (1000) according to one embodiment of the present invention, the lowest end of the cleaning ring (704) may be positioned at the same height as the lowest end of the guide blade (710).

[0165] As described above, it may be advantageous for the guide blade (710) to be formed with a relatively large height, in that it guides the air sucked in through the suction part (200) in one direction along the guide path (Fg).

[0166] On the other hand, if the height of the guide blade (710) is excessively large, the air moving along a ring-shaped path in one direction from the inlet (E) of the guide channel (Fg) may be blocked relatively much by the guide blade (710), and the flow resistance may increase.

[0167] Therefore, the height of the guide blade (710) needs to be formed to a size sufficient to concentrate the air sucked in through the suction part (200) in one direction, without being excessively large.

[0168] Accordingly, the lowest part of the guide blade (710) may be formed to be positioned at the same height as the lowest part of the cleaning ring (704), which may be the most appropriate height for the guide blade (710).

[0169] In this way, in a vacuum cleaner (1000) according to one embodiment of the present invention, since the lowest ends of the cleaning ring (704) and the guide blade (710) are each positioned at the same height, air is prevented from moving to the opposite side in the circumferential direction of the guide wall (701), and the flow resistance of air circulating along the circumference of the guide wall (701) can be reduced.

[0170] FIG. 12 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.

[0171] A vacuum cleaner (1000) according to one embodiment of the present invention may further include a dust cleaning shaft (720) that is installed along the longitudinal direction and is connected to one side of a dust cleaning unit (700) and moves up and down together with the dust cleaning unit (700).

[0172] That is, the dust cleaner (700) can be positioned to surround the cyclone unit (300) with one side connected to the dust cleaner shaft (720). And, when the dust cleaner shaft (720) moves up and down along the longitudinal direction, the dust cleaner (700) connected to the dust cleaner shaft (720) moves up and down together, and can remove dust stored in the dust container (110).

[0173] In particular, the dust cleaning shaft (720) is connected to the filter cleaning unit (500) described later or is connected independently to the cleaning lever (730), so that the user can easily raise and lower the dust cleaning unit (700) by moving the cleaning lever (730), which is located outside the vacuum cleaner (1000), along the longitudinal direction.

[0174] In this way, in the vacuum cleaner (1000) according to one embodiment of the present invention, one side of the dust cleaning unit (700) is coupled to the dust cleaning shaft (720) installed along the longitudinal direction and is raised together, so the structure for the installation and raising of the dust cleaning unit (700) can be made simpler.

[0175] A vacuum cleaner (1000) according to one embodiment of the present invention may further include a pre-filter section (400) and a filter cleaning section (500).

[0176] 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).

[0177] 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.

[0178] 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).

[0179] 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).

[0180] 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.

[0181] 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).

[0182] 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).

[0183] 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).

[0184] 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.

[0185] 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.

[0186] That is, a cleaner support body (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 body (520).

[0187] 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).

[0188] 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).

[0189] 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.

[0190] 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, 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.

[0191] 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.

[0192] 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).

[0193] Here, the filter cleaning unit (500) may further include a cleaner cover (530) that covers the upper surface of the filter cleaner (510) and is coupled to the cleaner support body (520).

[0194] That is, 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).

[0195] If 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).

[0196] 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.

[0197] In addition, when the dust cleaner (700) and the filter cleaner (510) 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.

[0198] 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).

[0199] Here, 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 the filter cleaning member (510) and moves up and down together with the filter cleaning member (510).

[0200] 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).

[0201] In relation to the structure of the filter cleaning unit (500) as described above, the filter cleaning unit (500) and the dust cleaning unit (700) can be connected and raised together.

[0202] That is, as shown in FIG. 12, when the user moves the cleaning lever (730), not only the dust cleaner (700) but also the filter cleaner (500) connected thereto can be moved together.

[0203] 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 (400) by the filter cleaner (500) can be performed simultaneously.

[0204] In this way, the vacuum cleaner (1000) according to one embodiment of the present invention is connected so that the filter cleaning unit (500), which removes dust collected in the pre-filter unit (400), is raised together with the dust cleaning unit (700), thereby allowing dust removal from the pre-filter unit (400) and the dust container (110) to be performed together through a single operation by the user, thus improving the convenience of use.

[0205]

[0206] Although specific embodiments of the present invention have been described and illustrated above, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should not be understood individually from the technical spirit or perspective of the present invention, and the modified embodiments should be considered to fall within the scope of the claims of the present invention.

[0207] According to at least one embodiment of the present invention, a guide fence is spaced apart from the outer side of a guide wall, and a guide cover connects the upper ends of each of the guide wall and the guide fence to form a guide channel, thereby minimizing the narrow section between the guide wall and the guide fence, so that foreign substances of a certain size or larger can be smoothly sucked in, and thus the suction performance for cleaning can always be maintained in an appropriate state.

[0208] 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.

[0209] In addition, according to at least one embodiment of the present invention, a guide blade is installed at the portion where the guide channel is connected to the suction part, thereby forming an air flow direction on one side in the circumferential direction of the guide wall, so that air movement for forming a cyclone flow can be smoothly achieved.

[0210] In addition, according to at least one embodiment of the present invention, the blade inclination of the guide blade is formed to be inclined toward one side in the circumferential direction of the guide wall, thereby minimizing the flow resistance of the sucked air, so that a suction airflow for cleaning can be smoothly formed even with a relatively small suction force.

[0211] In addition, according to at least one embodiment of the present invention, the upper portion of the blade inclined body formed to be bent is coupled to the guide wall and the remaining portion is spaced apart from the guide wall, so the flow resistance of air circulating along the perimeter of the guide wall can be reduced.

[0212] In addition, according to at least one embodiment of the present invention, since the blade parallel of the guide blade is formed parallel to the inner surface of the dust bin, it is possible to prevent foreign matter from accumulating between the inner surface of the dust bin and the guide blade.

[0213] In addition, according to at least one embodiment of the present invention, a suction blade continuous with a guide blade is installed in the suction section along a virtual extension line to form an air flow path direction together with the guide blade, so that air can be moved from the suction section in a direction to form a cyclone flow.

[0214] In addition, according to at least one of the embodiments of the present invention, since the guide fence is formed relatively small at the inlet portion of the guide channel in the direction of air movement along the guide channel, the air inlet area of ​​the inlet portion of the guide channel can be formed larger.

[0215] In addition, according to at least one embodiment of the present invention, since the guide cover is formed relatively high at the inlet portion of the guide channel in the direction of air movement along the guide channel, the air circulating along the circumference of the guide wall can be guided to move downward.

[0216] In addition, according to at least one embodiment of the present invention, since a cleaning ring is attached to the bottom of the guide wall, the dust between the dust container and the cyclone part can be evenly shaken off and compressed by the cleaning ring during the lifting process of the dust cleaner.

[0217] In addition, according to at least one embodiment of the present invention, the cleaning ring is formed with a shape in which the outer diameter decreases toward the bottom, so that the compression of dust can be performed more smoothly during the downward movement of the dust cleaner.

[0218] In addition, according to at least one embodiment of the present invention, since the cleaning ring is made of an elastic material, it is possible to prevent the cleaning ring from being deformed or damaged by external force during the lifting and lowering process of the dust cleaner.

[0219] In addition, according to at least one embodiment of the present invention, since the lowest ends of the cleaning ring and the guide blade are each positioned at the same height, the flow resistance of the air circulating along the circumference of the guide wall can be reduced while preventing air from moving to the opposite side in the circumference direction of the guide wall.

[0220] In addition, according to at least one embodiment of the present invention, since one side of the dust cleaning unit is coupled to a dust cleaning shaft installed along the longitudinal direction and moves up and down together, the structure for installing and moving the dust cleaning unit can be made simpler.

[0221] In addition, according to at least one embodiment of the present invention, a filter cleaning unit for removing dust collected in a pre-filter unit is connected to be raised and lowered together with a dust cleaning unit, so that dust removal from both the pre-filter unit and the dust bin is performed simultaneously through a single operation by a user, thereby improving convenience of use.
