Description

Technical Field

[0001] The present invention relates to a cleaner workstation, and more particularly, to a cleaner workstation that fixes a cleaner using suction force generated by a dust collecting motor. Background Art

[0002] Generally, a cleaner is a household appliance that sucks in small garbage or dust by using an electric air suction method and fills a dust collecting bin located inside the product, and is usually called a vacuum cleaner.

[0003] Such cleaners can be classified into a manual cleaner in which a user directly moves the cleaner while cleaning and an automatic cleaner that cleans while autonomously moving. According to the type of cleaner, the manual cleaner can be classified into a horizontal cleaner, an upright cleaner, a hand-held cleaner, a stick cleaner, etc.

[0004] Among household cleaners, in the past, most horizontal cleaners were used, but recently, there has been a trend of mostly using hand-held cleaners and stick cleaners that have improved usability through the integration of a dust collecting bin and a cleaner body.

[0005] The main body and the suction port of the horizontal cleaner are connected by a rubber tube or a hose, and a brush can be inserted into the suction port as needed.

[0006] The hand-held cleaner (Hand Vacuum Cleaner) maximizes portability. Although it is light in weight, its length is short, so the area for cleaning while sitting is somewhat limited. Therefore, it is used for cleaning local areas such as on a desk or a sofa or inside a car.

[0007] The stick cleaner can be used while standing, so it can be cleaned without bending over. Therefore, it is beneficial for cleaning while moving in a wider area. If the hand-held cleaner is used for cleaning a narrow space, the stick cleaner can be used for cleaning a wider space than it and can clean high places that cannot be reached by hand. Recently, the stick cleaner is provided in a modular manner, so that for various objects, the cleaner type can be actively changed and then used.

[0008] As a prior patent document, a cleaner workstation that captures dust inside the dust collecting bin of a cleaner is disclosed in Korean Patent Publication No. 10-2022-0052602.

[0009] At this time, the fixing unit of the above prior patent document is configured to include a fixing member that fixes the dust collecting bin by the power provided by a fixing unit motor, a fixing unit driving gear that rotates by the power of the fixing unit motor, a first rack that converts the rotational force of the fixing unit motor into a linear movement, and a fixing unit link rod that links the first rack and the fixing member.

[0010] However, in order to move the above-mentioned fixed component, in addition to the above-mentioned fixed component, the above-mentioned fixed unit also needs to be provided with a fixed part motor, various gears, and a plurality of link rods, so there are problems of complex structure, power consumption, and increased manufacturing cost. Summary of the Invention

[0011] Technical Problems to be Solved

[0012] The present invention is made to improve the problems of the existing sweeper workstation as described above. The technical problem to be solved is to provide a sweeper workstation capable of simplifying the structure and operation for fixing a dust collection bucket.

[0013] Moreover, the technical problem to be solved is to provide a sweeper workstation that can fix the sweeper only by the suction force generated by the dust collection motor.

[0014] Means for Solving the Technical Problems

[0015] In order to solve the above-mentioned problems, the sweeper workstation according to the present invention may include: a housing; a coupling part disposed in the housing and including a coupling surface to which at least a part of the sweeper is coupled; a dust collection part accommodated inside the housing to capture dust inside the dust collection bucket of the sweeper; a dust collection motor accommodated inside the housing to generate a suction force for sucking dust inside the dust collection bucket; and a fixing part that fixes the sweeper when the sweeper is coupled to the coupling part, wherein the fixing part includes a fixing component that moves from the outside of the dust collection bucket toward the dust collection bucket by the suction force generated by the dust collection motor when the sweeper is coupled to the coupling part.

[0016] The above-mentioned fixing component may be rotatably coupled to the above-mentioned coupling part.

[0017] When the above-mentioned dust collection motor operates, the above-mentioned fixing component may rotate in a direction approaching the dust collection bucket to fix the dust collection bucket.

[0018] When the operation of the above-mentioned dust collection motor ends, due to its own weight, the above-mentioned fixing component may rotate in a direction away from the dust collection bucket.

[0019] The sweeper workstation according to the present invention may further include: a bypass flow path, one end of which is connected to the above-mentioned coupling part to transmit the suction force generated by the above-mentioned dust collection motor to the above-mentioned fixing component.

[0020] To solve the problems described above, the sweeper workstation according to the present invention may include: a housing; a coupling portion disposed in the housing, including a coupling surface to which at least a part of the sweeper is coupled; a dust collection portion housed inside the housing for capturing dust inside the dust collection bucket of the sweeper; a dust collection motor housed inside the housing for generating a suction force for sucking dust inside the dust collection bucket; and a fixing portion for fixing the sweeper when the sweeper is coupled to the coupling portion, wherein the fixing portion includes a fixing member rotatably coupled to the coupling portion and rotated by the suction force generated by the dust collection motor, and in a state where the sweeper is coupled to the coupling portion, the center of gravity of the fixing member is located outside the rotation center of the fixing member with respect to the dust collection bucket.

[0021] The sweeper workstation according to the present invention may further include: a virtual dust collection bucket central axis penetrating along the length direction of the dust collection bucket, wherein, in a state where the sweeper is coupled to the coupling portion, the horizontal distance between the dust collection bucket central axis and the center of gravity of the fixing member is longer than the horizontal distance between the dust collection bucket central axis and the rotation center of the fixing member.

[0022] When the dust collection motor operates, the fixing member may rotate in a direction approaching the dust collection bucket to fix the dust collection bucket.

[0023] When the operation of the dust collection motor ends, due to its own weight, the fixing member may rotate in a direction away from the dust collection bucket.

[0024] The sweeper workstation according to the present invention may further include: a bypass flow path, one end of which is connected to the coupling portion for transmitting the suction force generated by the dust collection motor to the fixing member.

[0025] The rotation center of the fixing member may be located between one end of the bypass flow path and the center of gravity of the fixing member.

[0026] Advantages of the Invention

[0027] As described above, the sweeper workstation according to the present invention does not require a separate motor for providing power, a gear for transmitting the power, and a link rod for connecting the gear and the fixing member, so it has the effect of being able to simplify the structure for fixing the dust collection bucket.

[0028] Moreover, it has the effects of being able to achieve the light weight of the sweeper workstation, being able to minimize power consumption, and being able to reduce the manufacturing cost of the sweeper workstation.

[0029] Moreover, it has the effect of being able to move the fixing member only by the suction force generated by the dust collection motor, thereby stably fixing the cleaning machine.

[0030] In addition, it has the effect of being able to release the fixation of the cleaning machine by the rotation brought about by the self-weight of the fixing member when the operation of the dust collection motor ends. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 A perspective view of a cleaning machine system composed of a cleaning machine workstation and a cleaning machine according to an embodiment of the present invention is shown. Figures 2 to 4 A schematic diagram of the composition of a cleaning machine system according to various embodiments of the present invention is shown.

[0049] Refer to Figure 1 and Figure 2 , a cleaning machine system 10 according to an embodiment of the present invention may include a cleaning machine workstation 100 and a cleaning machine 200.

[0050] The cleaning machine system 10 may include a cleaning machine workstation 100. The cleaning machine 200 may be coupled to the cleaning machine workstation 100. Specifically, the main body of the cleaning machine 200 may be coupled to the side of the cleaning machine workstation 100. The cleaning machine workstation 100 may remove the dust from the dust collection bucket 220 of the cleaning machine 200.

[0051] On the other hand, Figure 3 and Figure 4 A diagram for explaining the cleaning machine in the cleaning machine system according to an embodiment of the present invention is shown.Figure 5 The figure shows the lower side of the dust collecting bucket of the sweeper according to an embodiment of the present invention.

[0052] First, the structure of the sweeper 200 will be described below with reference to Figures 1 to 5 explain the structure of the sweeper 200.

[0053] The sweeper 200 may refer to a sweeper manually operated by a user. For example, the sweeper 200 may refer to a handheld sweeper or a pole sweeper.

[0054] The sweeper 200 may be placed on the sweeper workstation 100. The sweeper 200 may be supported by the sweeper workstation 100. The sweeper 200 may be coupled to the sweeper workstation 100.

[0055] On the other hand, in an embodiment of the present invention, the direction of the sweeper 200 may be defined based on when the bottom surfaces (lower sides) of the dust collecting bucket 220 and the battery housing 230 are placed on the ground.

[0056] At this time, the front may refer to the direction in which the suction part 212 is arranged based on the suction motor 214, and the rear refers to the direction in which the handle 216 is arranged based on the suction motor 214. In addition, based on when observing the suction part 212 from the suction motor 214, the direction arranged on the right side may be referred to as the right side, and the direction arranged on the left side is referred to as the left side. And, in an embodiment of the present invention, based on when the bottom surfaces (lower sides) of the dust collecting bucket 220 and the battery housing 230 are placed on the ground, the upper side and the lower side may be defined in a direction perpendicular to the ground.

[0057] The sweeper 200 may include a main body 210. The main body 210 may include a main body housing 211, a suction part 212, a dust separation part 213, a suction motor 214, an exhaust cover 215, a handle 216, and an operation part 218.

[0058] The main body housing 211 may form the appearance of the sweeper 200. The main body housing 211 may provide a space for accommodating the suction motor 214 and a filter (not shown) inside. The main body housing 211 may be configured in a shape similar to a cylindrical shape.

[0059] The suction part 212 may protrude outward from the main body housing 211. As an example, the suction part 212 may be formed in a cylindrical shape with an open interior. The suction part 212 may be coupled to the extension pipe 250. The suction part 212 may provide a flow path through which air including dust can flow.

[0060] On the other hand, in the present embodiment, a virtual line penetrating the inside of the suction part 212 configured in a cylindrical shape may be formed.

[0061] The dust separation unit 213 can communicate with the suction unit 212. The dust separation unit 213 can separate the dust inhaled into the interior through the suction unit 212. The space inside the dust separation unit 213 can communicate with the space inside the dust collection bucket 220.

[0062] For example, the dust separation unit 213 can include at least one or more cyclone units. The above cyclone units can separate dust through cyclone flow. In addition, the space inside the dust separation unit 213 can communicate with the suction unit 212. Therefore, the air and dust inhaled through the suction unit 212 can flow spirally along the inner surface of the dust separation unit 213. Therefore, a cyclone flow can be generated in the internal space of the dust separation unit 213.

[0063] The dust separation unit 213 communicates with the suction unit 212 and is configured in a structure that applies the principle of a dust collector using centrifugal force to separate the dust inhaled into the interior of the main body 210 through the suction unit 212.

[0064] The dust separation unit 213 can also include a secondary cyclone that separates dust from the air discharged from the cyclone again. At this time, the secondary cyclone can be located inside the cyclone to minimize the size of the dust separation unit. The secondary cyclone can include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone can be distributed to the plurality of cyclone bodies to pass through.

[0065] At this time, the axis of the cyclone flow of the secondary cyclone can also extend in the vertical direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone can be coaxial in the vertical direction, and these can be collectively referred to as the axis of the cyclone flow of the dust separation unit 213.

[0066] The suction motor 214 can generate a suction force for inhaling air. The suction motor 214 can be housed in the main body housing 211. The suction motor 214 can generate a suction force by rotating. As an example, the suction motor 214 can be formed to be similar to a cylindrical shape.

[0067] On the other hand, in this embodiment, a virtual suction motor axis extending the rotation axis of the suction motor 214 can be formed.

[0068] The exhaust cover 215 can be disposed on one side in the axial direction of the main body housing 211. A filter for filtering air can be housed in the exhaust cover 215. As an example, a high-efficiency (HEPA) filter can be housed in the exhaust cover 215.

[0069] An exhaust port 215a for discharging the air inhaled by the suction force of the suction motor 214 can be formed in the exhaust cover 215.

[0070] A flow guiding member can be disposed in the exhaust cover 215. The flow guiding member can guide the flow of the air discharged through the exhaust port 215a.

[0071] The handle 216 can be held by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed to be similar to a cylindrical shape. Alternatively, the handle 216 can be formed into a bent cylindrical shape. The handle 216 is arranged at a predetermined angle with respect to the main body housing 211, the suction motor 214, or the dust separation unit 213.

[0072] The handle 216 can include a gripping portion formed in a columnar shape for the user to hold, a first extension portion connected to one end portion in the longitudinal direction (axial direction) of the gripping portion and extending toward the suction motor 214, and a second extension portion connected to the other end portion in the longitudinal direction (axial direction) of the gripping portion and extending toward the dust collection bin 220.

[0073] On the other hand, in the present embodiment, a virtual handle through-line extending in the longitudinal direction (axial direction of the column) of the gripping portion and penetrating the gripping portion can be formed.

[0074] As an example, the handle through-line can be a virtual line formed inside the cylindrical handle 216, and can also be a virtual line formed parallel to at least a part of the outer side surface (outer surface) of the gripping portion.

[0075] The upper surface of the handle 216 can form a partial appearance of the upper surface of the cleaner 200. Thus, when the user holds the handle 216, it is possible to prevent a part of the cleaner 200 from coming into contact with the user's arm.

[0076] The first extension portion can extend from the gripping portion toward the main body housing 211 or the suction motor 214. At least a part of the first extension portion can extend in the horizontal direction.

[0077] The second extension portion can extend from the gripping portion toward the dust collection bin 220. At least a part of the second extension portion can extend in the horizontal direction.

[0078] The operation unit 218 can be arranged on the handle 216. The operation unit 218 can be arranged on an inclined surface formed in the upper region of the handle 216. The user can input an operation or stop command for the cleaner 200 through the operation unit 218.

[0079] The cleaner 200 can include a dust collection bin 220. The dust collection bin 220 can communicate with the dust separation unit 213. The dust collection bin 220 can store the dust separated by the dust separation unit 213.

[0080] The dust collection bin 220 can include a dust collection bin main body 221, a discharge cover 222, a dust collection bin compression rod 223, and a compression member (not shown).

[0081] The dust collection bucket main body 221 can provide a space capable of storing the dust separated by the dust separation unit 213. As an example, the dust collection bucket main body 221 can be formed to be similar to a cylindrical shape.

[0082] On the other hand, in the present embodiment, a virtual dust collection bucket central axis C can be formed to penetrate the inside (inner space) of the dust collection bucket main body 221 and extend along the length direction of the dust collection bucket main body 221 (the axial direction in the cylindrical dust collection bucket main body 221). At this time, when viewed from the cross-sectional direction perpendicular to the length direction of the dust collection bucket main body 221, the dust collection bucket central axis C can be formed to pass through the center of the above cross-section.

[0083] A part of the lower side surface (bottom surface) of the dust collection bucket main body 221 can be opened. And a lower surface extension part 221a can be formed on the lower side surface (bottom surface) of the dust collection bucket main body 221. The lower surface extension part 221a can be formed to block a part of the lower side surface of the dust collection bucket main body 221.

[0084] The dust collection bucket 220 can include a discharge cover 222. The discharge cover 222 can be disposed on the lower side surface of the dust collection bucket 220.

[0085] The discharge cover 222 can be set to open or close one end portion in the length direction of the dust collection bucket main body 221. Specifically, the discharge cover 222 can selectively open or close the lower part of the dust collection bucket 220 that opens downward.

[0086] The discharge cover 222 can include a cover main body 222a and a hinge part 222b. The cover main body 222a can be formed to block a part of the lower side surface of the dust collection bucket main body 221. The cover main body 222a can rotate downward with the hinge part 222b as a reference. The hinge part 222b can be disposed adjacent to the battery housing 230. The hinge part 222b can be provided with a torsion spring 222d. Therefore, in the case of detaching the discharge cover 222 from the dust collection bucket main body 221, by the elastic force of the torsion spring 222d, the cover main body 222a is supported in a state of rotating by a predetermined angle or more around the hinge part 222b in the dust collection bucket main body 221.

[0087] The discharge cover 222 can be coupled to the dust collection bucket 220 by hook coupling. On the other hand, the discharge cover 222 can be detached from the dust collection bucket 220 by a coupling rod 222c. The coupling rod 222c can be disposed in front of the dust collection bucket. Specifically, the coupling rod 222c can be disposed on the front side outer surface of the dust collection bucket 220. When an external force is applied, the coupling rod 222c can elastically deform the hook extending from the cover main body 222a to release the hook coupling between the cover main body 222a and the dust collection bucket main body 221.

[0088] When the discharge cover 222 is closed, the lower side of the dust collection bin 220 can be blocked (sealed) by the discharge cover 222 and the lower extension part 221a.

[0089] The dust collection bin 220 may include a dust collection bin compression rod 223 (refer to Figure 4 ). The dust collection bin compression rod 223 may be disposed outside the dust collection bin 220 or the dust separation unit 213. The dust collection bin compression rod 223 may be disposed outside the dust collection bin 220 or the dust separation unit 213 in a vertically movable manner. The dust collection bin compression rod 223 may be connected to a compression member (not shown). When the dust collection bin compression rod 223 moves downward due to an external force, the compression member (not shown) may also move downward together. Thereby, convenience for the user can be provided. The compression member (not shown) and the dust collection bin compression rod 223 may return to their original positions through an elastic member (not shown). Specifically, when the external force applied to the dust collection bin compression rod 223 is released, the elastic member may move the dust collection bin compression rod 223 and the compression member (not shown) upward.

[0090] The compression member (not shown) may be disposed inside the dust collection bin main body 221. The compression member may move within the internal space of the dust collection bin main body 221. Specifically, the compression member may move vertically within the dust collection bin main body 221. Thereby, the compression member can compress the dust inside the dust collection bin main body 221 downward. Also, when the discharge cover 222 is detached from the dust collection bin main body 221 to open the lower part of the dust collection bin 220, the compression member moves from the upper part to the lower part of the dust collection bin 220, and impurities such as residual dust inside the dust collection bin 220 can be removed. Thereby, by avoiding residual dust remaining inside the dust collection bin 220, the suction power of the cleaner can be improved. Moreover, by avoiding residual dust remaining inside the dust collection bin 220, the malodor generated by the residue can be removed.

[0091] The cleaner 200 may include a battery housing 230. The battery 240 may be housed inside the battery housing 230. The battery housing 230 may be disposed below the handle 216. As an example, the battery housing 230 may be in the shape of a hexahedron with an open lower part. The rear surface of the battery housing 230 may be connected to the handle 216.

[0092] The battery housing 230 may include a housing part that opens downward. The battery 240 can be loaded and unloaded through the housing part of the battery housing 230.

[0093] The cleaner 200 may include a battery 240.

[0094] For example, the battery 240 can be detachably coupled to the cleaner 200. The battery 240 can be detachably coupled to the battery housing 230. As an example, the battery 240 can be inserted into the interior of the battery housing 230 from below the battery housing 230. With this structure, the portability of the cleaner 200 can be improved.

[0095] Differently, the battery 240 can be integrally provided inside the battery housing 230. At this time, the lower surface of the battery 240 is not exposed to the outside.

[0096] The battery 240 can supply power to the suction motor 214 of the cleaner 200. The battery 240 can be disposed below the handle 216. The battery 240 can be disposed behind the dust collection bin 220.

[0097] According to an embodiment, when the battery 240 is coupled to the battery housing 230, the lower surface of the battery 240 can be exposed to the outside. When the cleaner 200 is placed on the ground, the battery 240 may be placed on the ground, so the battery 240 can be immediately detached from the battery housing 230. Also, since the lower surface of the battery 240 is exposed to the outside and directly contacts the outside air of the battery 240, the cooling performance of the battery 240 can be improved.

[0098] On the other hand, when the battery 240 is integrally fixed to the battery housing 230, the structure for loading and unloading the battery 240 and the battery housing 230 can be omitted, so the overall size of the cleaner 200 can be reduced and weight reduction can be achieved.

[0099] The cleaner 200 can include an extension tube 250. The extension tube 250 can communicate with the cleaning module 260. The extension tube 250 can communicate with the main body 210. The extension tube 250 can communicate with the suction part 212 of the main body 210. The extension tube 250 can be formed in a long cylindrical shape.

[0100] The main body 210 can be connected to the extension tube 250. The main body 210 can be connected to the cleaning module 260 through the extension tube 250. The main body 210 can generate suction through the suction motor 214 and provide suction to the cleaning module 260 through the extension tube 250. External dust can flow into the main body 210 through the cleaning module 260 and the extension tube 250.

[0101] The cleaner 200 can include a cleaning module 260. The cleaning module 260 can communicate with the extension tube 250. Therefore, external air can flow into the main body 210 of the cleaner 200 after passing through the cleaning module 260 and the extension tube 250 by the suction generated in the main body 210 of the cleaner 200.

[0102] The dust in the dust collection bucket 220 of the sweeper 200 can be captured by gravity and the suction force of the dust collection motor 191 into the dust collection part 170 of the sweeper workstation 100. Thus, the dust in the dust collection bucket can be removed without the user performing other operations, so user convenience can be provided. Also, the trouble of the user having to empty the dust collection bucket every time can be eliminated. Also, when emptying the dust collection bucket, dust scattering can be prevented.

[0103] The sweeper 200 can be coupled to the side of the housing 110. Specifically, the main body 210 of the sweeper 200 can be placed on the coupling part 120. More specifically, the dust collection bucket 220 and the battery housing 230 of the sweeper 200 can be coupled to the coupling surface 121, the outer surface of the dust collection bucket main body 221 can be coupled to the dust collection bucket guide surface 122, and the suction part 212 can be coupled to the suction part guide surface 126 of the coupling part 120. In this case, the central axis of the dust collection bucket 220 can be arranged in a direction parallel to the ground, and the extension pipe 250 is arranged in a direction perpendicular to the ground.

[0104] Refer to Figure 1 and Figure 2 , and the sweeper workstation 100 of the present invention will be described below.

[0105] The sweeper workstation 100 can be configured with the sweeper 200. The sweeper 200 can be coupled to the side of the sweeper workstation 100. Specifically, the main body of the sweeper 200 can be coupled to the side of the sweeper workstation 100. The sweeper workstation 100 can remove the dust from the dust collection bucket 220 of the sweeper 200.

[0106] The sweeper workstation 100 can include a housing 110. The housing 110 can form the appearance of the sweeper workstation 100. Specifically, the housing 110 can be formed in a columnar shape including at least one or more outer wall surfaces. As an example, the housing 110 can be formed in a shape similar to a square column.

[0107] Inside the housing 110, a space for accommodating the dust collection part 170 for storing dust and the dust suction module 190 for generating a flow force that causes the dust to concentrate in the dust collection part 170 can be formed.

[0108] The housing 110 can include a bottom surface 111, an outer wall surface 112, and an upper surface 113.

[0109] The bottom surface 111 can support the lower side in the gravity direction of the dust suction module 190. That is, the bottom surface 111 can support the lower side of the dust collection motor 191 of the dust suction module 190.

[0110] At this time, the bottom surface 111 can be arranged facing the ground. The bottom surface 111 can be arranged parallel to the ground, and can also be arranged at a predetermined angle inclined from the ground. With this configuration, the dust collection motor 191 can be stably supported, and has the advantage of being able to maintain the balance of the overall weight even when the sweeper 200 is combined.

[0111] On the other hand, according to an embodiment, the bottom surface 111 may further include a ground support portion 111a, which increases the area of contact with the ground in order to prevent the sweeper workstation 100 from falling down and maintaining balance. As an example, the ground support portion may be a plate-like shape extending from the bottom surface 111, or may be a shape in which one or more frames protrude and extend along the ground direction from the bottom surface 111.

[0112] The outer wall surface 112 may refer to a surface formed along the direction of gravity, or may refer to a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface perpendicularly connected to the bottom surface 111. As a different embodiment, the outer wall surface 112 may also be arranged at a predetermined angle inclined from the bottom surface 111.

[0113] The outer wall surface 112 may be configured to include at least one surface. As an example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0114] At this time, in the present embodiment, the first outer wall surface 112a may be arranged on the front of the sweeper workstation 100. Here, the front refers to the surface that exposes the sweeper 200 when the sweeper 200 is combined with the sweeper workstation 100. Therefore, the first outer wall surface 112a may form the front appearance of the sweeper workstation 100.

[0115] On the other hand, in order to help understand the present embodiment, the directions are defined as follows. In the present embodiment, the directions may be defined when the sweeper 200 is placed on the sweeper workstation 100.

[0116] When the sweeper 200 is placed on the sweeper workstation 100, the direction in which the sweeper 200 is exposed outside the sweeper workstation 100 may be referred to as the front.

[0117] From another perspective, when the sweeper 200 is placed on the sweeper workstation 100, the direction in which the suction motor 214 of the sweeper 200 is arranged may be referred to as the front. Additionally, the opposite direction of the direction in which the suction motor 214 is arranged in the sweeper workstation 100 may be referred to as the rear.

[0118] In addition, taking the internal space of the housing 110 as a reference, the surface facing the front direction may be referred to as the rear of the sweeper workstation 100. Therefore, the rear may refer to the direction in which the second outer wall surface 112b is formed.

[0119] In addition, with reference to the internal space of the housing 110, when observing the front surface described above, the left side surface can be referred to as the left surface, and the right side surface can be referred to as the right surface. Therefore, the left surface can refer to the direction in which the third outer wall surface 112c is formed, and the right surface can refer to the direction in which the fourth outer wall surface 112d is formed.

[0120] The first outer wall surface 112a is formed in a planar shape, and it can also be formed in a curved surface shape as a whole, or can be formed to include a curved surface locally.

[0121] The first outer wall surface 112a can have an appearance corresponding to the shape of the cleaning machine 200. Specifically, the coupling part 120 can be arranged on the first outer wall surface 112a. With this configuration, the cleaning machine 200 can be coupled to the cleaning machine workstation 100 and can be supported by the cleaning machine workstation 100. The specific structure of the coupling part 120 will be described later.

[0122] On the other hand, a structure for placing various types of cleaning modules 260 used in the cleaning machine 200 can also be added to the first outer wall surface 112a.

[0123] In this embodiment, the second outer wall surface 112b can be the surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b can be arranged at the back of the cleaning machine workstation 100. Here, the back can be the surface facing the surface to which the cleaning machine 200 is coupled. Therefore, the second outer wall surface 112b can form the appearance at the back of the cleaning machine workstation 100.

[0124] As an example, the second outer wall surface 112b can be formed in a planar shape. With this configuration, the cleaning machine workstation 100 can be closely attached to the indoor wall, and the cleaning machine workstation 100 can be stably supported.

[0125] As another example, a structure for placing various types of cleaning modules 260 used in the cleaning machine 200 can also be added to the second outer wall surface 112b.

[0126] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d can refer to the surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. At this time, the third outer wall surface 112c can be arranged on the left side of the workstation 100, and the fourth outer wall surface 112d is arranged on the right side of the cleaning machine workstation 100. Differently, it can also be that the third outer wall surface 112c is arranged on the right side of the cleaning machine workstation 100, and the fourth outer wall surface 112d is arranged on the left side of the cleaning machine workstation 100.

[0127] The third outer wall surface 112c or the fourth outer wall surface 112d can be formed in a planar shape, and it can also be formed in a curved surface shape as a whole, or can be formed to include a curved surface locally.

[0128] On the other hand, a structure for placing cleaning modules 260 in various ways used in the cleaning machine 200 may be added to the third outer wall surface 112c or the fourth outer wall surface 112d.

[0129] The upper surface 113 may form the upper appearance of the cleaning machine workstation. That is, the upper surface 113 may refer to the surface that is disposed at the uppermost side in the direction of gravity in the cleaning machine workstation and is thus exposed to the outside.

[0130] For reference, in the present embodiment, the upper side and the lower side may respectively refer to the upper side and the lower side in the direction of gravity (the direction perpendicular to the ground) when the cleaning machine workstation 100 is disposed on the ground.

[0131] At this time, the upper surface 113 may be disposed parallel to the ground, or may be disposed at a predetermined angle inclined from the ground.

[0132] The upper surface 113 may be provided with a display unit 410. As an example, the display unit 410 may display the status of the cleaning machine workstation 100, the status of the cleaning machine 200, and in addition, may also display information such as the cleaning progress and a map of the cleaning area.

[0133] On the other hand, according to an embodiment, the upper surface 113 may be configured to be detachable from the outer wall surface 112. At this time, when the upper surface 113 is detached, the internal space surrounded by the outer wall surface 112 may accommodate a battery detached from the cleaning machine 200, and terminals (not shown) for charging the detached battery may be provided.

[0134] Figure 6 The figure shows a diagram for explaining a coupling part in a cleaning machine workstation according to an embodiment of the present invention, Figure 7 The figure shows a diagram for explaining a fixing unit in a cleaning machine workstation according to an embodiment of the present invention, Figure 8 and Figure 9 The figure shows a diagram for explaining the relationship between a cleaning machine and a door unit in a cleaning machine workstation according to an embodiment of the present invention, Figure 10 The figure shows a diagram for explaining the relationship between a cleaning machine and an open lid unit in a cleaning machine workstation according to an embodiment of the present invention.

[0135] Referring to Figure 2 and Figure 6 , the coupling part 120 of the cleaning machine workstation 100 of the present invention will be described below.

[0136] The cleaning machine workstation 100 may include a coupling part 120 for coupling the cleaning machine 200. Specifically, the coupling part 120 is disposed on the first outer wall surface 112a, and the main body 210, the dust collection bucket 220, and the battery housing 230 of the cleaning machine 200 may be coupled to the coupling part 120.

[0137] The joint portion 120 may include a joint surface 121. The joint surface 121 may be disposed on the side surface of the housing 110. As an example, the joint surface 121 may refer to a surface formed as a groove recessed from the first outer wall surface 112a toward the inside of the sweeper workstation 100. That is, the joint surface 121 may refer to a surface having a height difference from the first outer wall surface 112a.

[0138] The sweeper 200 may be coupled to the joint surface 121. As an example, the joint surface 121 may contact the lower side surfaces of the dust collection bucket 220 and the battery housing 230 of the sweeper 200. Herein, the lower side surface may refer to the surface facing the ground when the user uses the sweeper 200 or places it on the ground.

[0139] As an example, the angle formed by the joint surface 121 and the ground may be a right angle. Thus, when the sweeper 200 is coupled to the joint surface 121, minimization of the space of the sweeper workstation 100 can be achieved.

[0140] As other examples, the joint surface 121 may be disposed at a predetermined angle inclined from the ground. Thus, when the sweeper 200 is coupled to the joint surface 121, the sweeper workstation 100 can be stably supported.

[0141] A dust passage hole 121a may be formed in the joint portion 120 so that air outside the housing 110 can flow into the interior. Specifically, the dust passage hole 121a may be formed in the joint surface 121 of the joint portion 120 so that air outside the housing 110 can flow into the interior. The dust passage hole 121a may be formed in the joint surface 121 so that air outside the housing 110 can flow into the interior. The dust passage hole 121a may be formed as a hole corresponding to the shape of the dust collection bucket 220 so that the dust in the dust collection bucket 220 flows into the dust collection unit 170. The dust passage hole 121a may be formed in the shape corresponding to the discharge cover 222 of the dust collection bucket 220. The dust passage hole 121a may be formed to communicate with an inhalation flow path portion 180 described later.

[0142] The joint portion 120 may include a dust collection bucket guide surface 122. The dust collection bucket guide surface 122 may be disposed on the first outer wall surface 112a. The dust collection bucket guide surface 122 may be connected to the first outer wall surface 112a. And, the dust collection bucket guide surface 122 may be connected to the joint surface 121.

[0143] The dust collection bucket guide surface 122 may be formed in the shape corresponding to the outer side surface of the dust collection bucket 220. The front outer side surface of the dust collection bucket 220 may be coupled to the dust collection bucket guide surface 122. Thus, convenience in coupling the sweeper 200 to the joint surface 121 can be provided.

[0144] On the other hand, the dust collection bucket guiding surface 122 may be formed with a protrusion moving hole 122a, and a pushing protrusion 151 described later may linearly move along the protrusion moving hole 122a. And, a gear box 155 for housing gears and the like of an opening unit 150 described later may be provided on the lower side in the direction of gravity of the dust collection bucket guiding surface 122. At this time, a guiding space 122b in which the pushing protrusion 151 can move may be formed between the dust collection bucket guiding surface 122 and the lower side surface and the upper side surface of the gear box 155. In addition, the guiding space 122b may communicate with the suction flow path portion 180 through a bypass hole 122c. That is, the protrusion moving hole 122a, the guiding space 122b, the bypass hole 122c, and the suction flow path portion 180 may form a bypass flow path (refer to Figure 9 ). With this configuration, there is an advantage that when the dust collection motor 191 operates in a state where the dust collection bucket 220 is coupled to the coupling portion 120, dust and the like remaining in the dust collection bucket 220 and the dust collection bucket guiding surface 122 can be sucked through the bypass flow path.

[0145] The coupling portion 120 may include guiding protrusions 123. The guiding protrusions 123 may be disposed on the coupling surface 121. The guiding protrusions 123 may protrude upward from the coupling surface 121. Two guiding protrusions 123 may be provided separately from each other. The distance between the two separately provided guiding protrusions 123 may correspond to the width of the battery case 230 of the cleaner 200. Thereby, convenience in coupling the cleaner 200 to the coupling surface 121 can be provided.

[0146] The coupling portion 120 may include side walls 124. The side walls 124 may refer to wall surfaces disposed on both side surfaces of the coupling surface 121 and may be perpendicularly connected to the coupling surface 121. The side walls 124 may be connected to the first outer wall surface 112a. And, the side walls 124 may constitute a surface connected to the dust collection bucket guiding surface 122. Thereby, the cleaner 200 can be stably housed.

[0147] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 may sense whether the cleaner 200 is coupled to the coupling portion 120.

[0148] The coupling sensor 125 may further include a contact sensor. As an example, the coupling sensor 125 may include a micro switch. At this time, the coupling sensor 125 may be disposed on the guiding protrusion 123. Therefore, when the battery case 230 or the battery 240 of the cleaner 200 is coupled between a pair of guiding protrusions 123, it contacts the coupling sensor 125, and the coupling sensor 125 may sense the coupling of the cleaner 200.

[0149] On the other hand, the coupling sensor 125 may further include a non-contact sensor. As an example, the coupling sensor 125 may include an ultraviolet sensor unit (IR sensor). At this time, the coupling sensor 125 may be disposed on the side wall 124. Therefore, when the dust collecting bin 220 or the main body 210 of the sweeper 200 reaches the coupling surface 121 after passing through the side wall 124, the coupling sensor 125 can sense the presence of the dust collecting bin 220 or the main body 210.

[0150] The coupling sensor 125 may face the dust collecting bin 220 or the battery housing 230 of the sweeper 200.

[0151] The coupling sensor 125 may serve as a means for determining whether power is applied to the battery 240 of the sweeper 200 and whether the sweeper 200 is coupled.

[0152] The coupling part 120 may include an inhalation part guide surface 126. The inhalation part guide surface 126 may be disposed on the first outer wall surface 112a. The inhalation part guide surface 126 may be connected to the dust collecting bin guide surface 122. The inhalation part 212 may be coupled to the inhalation part guide surface 126. The shape of the inhalation part guide surface 126 may be formed to correspond to the shape of the inhalation part 212.

[0153] The coupling part 120 may further include a fixing member access hole 127. The fixing member access hole 127 may be formed in a long hole shape along the side wall 124 so that the fixing member 310 can enter and exit. As an example, the fixing member access hole 127 may be a rectangular hole formed along the side wall 124. The fixing member 310 will be described in detail later.

[0154] With this structure, when the user couples the sweeper 200 to the coupling part 120 of the sweeper workstation 100, the main body 210 of the sweeper 200 can be stably disposed on the coupling part 120 through the dust collecting bin guide surface 122, the guide protrusion 123, and the inhalation part guide surface 126. Accordingly, convenience in coupling the dust collecting bin 220 and the battery housing 230 of the sweeper 200 to the coupling surface 121 can be provided.

[0155] Next, reference will be made to Figure 2 、 Figure 7 、 Figure 8 and Figure 10 to describe the door unit 140 of the present invention.

[0156] The sweeper workstation 100 of the present invention may include a door unit 140. The door unit 140 may be configured to open or close the dust passage hole 121a.

[0157] The door unit 140 may include a door 141, a door motor 142, and a door arm 143.

[0158] The door 141 is hinged to the joint surface 121 and can open or close the dust passing hole 121a. The door 141 may include a door body 141a.

[0159] The door body 141a may be formed in a shape capable of blocking the dust passing hole 121a. As an example, the door body 141a may be formed in a shape similar to a disk.

[0160] Based on the state that the door body 141a blocks the dust passing hole 121a, a hinge portion may be configured on the upper side of the door body 141a, and an arm coupling portion 141b may be configured on the lower side of the door body 141a.

[0161] The door body 141a may be formed into a shape that can achieve airtightness to the dust passage hole 121a. As an example, the outer side surface of the door body 141a exposed to the outside of the sweeper workstation 100 is formed to have a diameter corresponding to the diameter of the dust passage hole 121a, and the inner side surface disposed inside the sweeper workstation 100 is formed to have a diameter greater than the diameter of the dust passage hole 121a. In addition, there may be a height difference between the outer side surface and the inner side surface. On the other hand, the inner side surface of the door body 141a may be protrudingly formed with at least one or more reinforcing ribs for connecting the hinge portion and the machine arm joint portion 141b and strengthening the supporting force of the door body 141a.

[0162] The hinge part may be a means for hinge-connecting the door 141 to the connection surface 121. The hinge part is disposed at the upper end of the door body 141a and may be connected to the connection surface 121.

[0163] The arm coupling part 141b may be a means for rotatably coupling the door arm 143. The arm coupling part 141b may be disposed at the lower side of the door body 141a and rotatably coupled to the door body 141a, and the door arm 143 is rotatably coupled to the arm coupling part 141b.

[0164] With this structure, when the door 141 closes the dust hole 121a, the door arm 143 pulls the door body 141a, and the door body 141a rotates toward the inside of the cleaning machine workstation 100 with the hinge as the axis, thereby opening the dust hole 121a. On the other hand, when the dust hole 121a is opened, the door arm 143 pushes the door body 141a, and the door body 141a rotates toward the outside of the cleaning machine workstation 100 with the hinge 141b as the axis, thereby blocking the dust hole 121a.

[0165] On the other hand, when the cleaning machine 200 is combined with the cleaning machine workstation 100 and the discharge cover 222 is separated from the dust collecting bucket body 210, the door 141 can contact the discharge cover 222. In addition, as the door 141 rotates, the discharge cover 222 can rotate in conjunction with the door 141.

[0166] The door motor 142 can provide the power to rotate the door 141. Specifically, the door motor 142 can rotate the door arm 143 in the forward or reverse direction. Herein, the forward direction can refer to the direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 rotates forward, the dust passage hole 121a can be opened. And the reverse direction can refer to the direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 rotates in the reverse direction, at least a part of the dust passage hole 121a can be closed. The forward direction can be the direction opposite to the reverse direction.

[0167] The door arm 143 can connect the door 141 and the door motor 142, and use the power generated by the door motor 142 to open or close the door 141.

[0168] As an example, the door arm 143 can include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a can be coupled to the door motor 142. The first door arm 143a can rotate by the power of the door motor 142. The other end of the first door arm 143a is rotatably coupled to the second door arm 143b. The first door arm 143a can transfer the force transmitted from the door motor 142 to the second door arm 143b. One end of the second door arm 143b can be coupled to the first door arm 143a. The other end of the second door arm 143b can be coupled to the door 141. The second door arm 143b pulls or pushes the door 141, thereby opening or closing the dust passage hole 121a.

[0169] The door unit 140 can further include a door switch sensing unit 144. The door switch sensing unit 144 can be provided inside the housing 110 and can sense whether the door 141 is in the open state.

[0170] As an example, the door switch sensing unit 144 can be respectively disposed at both end portions of the rotational movement area of the door arm 143. As other examples, the door switch sensing unit 144 can be respectively disposed at both end portions of the movement area of the door 141.

[0171] Therefore, when the door arm 143 moves to a preset open door position or the door 141 is opened to a predetermined position, the door switch sensing unit 144 can sense that the door is opened. And when the door arm 143 moves to a preset closed door position or the door 141 is opened to a predetermined position, the door switch sensing unit 144 can sense that the door has been opened.

[0172] The door switch sensing unit 144 can further include a contact sensor. As an example, the door switch sensing unit 144 can include a micro switch.

[0173] On the other hand, the door switch sensing unit 144 may further include a non-contact sensor. As an example, the door switch sensing unit 144 may include an ultraviolet sensor unit (IR sensor).

[0174] With this configuration, the door unit 140 selectively opens or closes at least a part of the joint surface 121, so that the outside of the first outer wall surface 112a can be communicated with the suction flow path unit 180 and / or the dust collection unit 170.

[0175] The door unit 140 can be opened together when the discharge cover 222 of the cleaner 200 is opened. And when the door unit 140 is closed, the discharge cover 222 of the cleaner 200 can be closed in linkage therewith.

[0176] When removing the dust from the dust collection bucket 220 of the cleaner 200, the door motor 142 rotates the door 141, so that the discharge cover 222 can be coupled to the dust collection bucket main body 221. Specifically, the door motor 142 rotates the door 141, so that the door 141 rotates, and the rotating door 141 pushes the discharge cover 222 toward the dust collection bucket main body 221.

[0177] Refer to the following Figure 2 、 Figure 9 and Figure 10 to describe the opening cover unit 150 of the present invention.

[0178] The cleaner workstation 100 of the present invention may include an opening cover unit 150. The opening cover unit 150 is disposed at the joint portion 120 and can open the discharge cover 222 of the cleaner 200.

[0179] The opening cover unit 150 may include a pushing protrusion 151, an opening cover motor 152, an opening cover gear 153, a support plate 154, and a gear box 155.

[0180] When the cleaner 200 is combined, the pushing protrusion 151 can move in the manner of pressing the coupling rod 222c.

[0181] The pushing protrusion 151 may be disposed on the dust collection bucket guiding surface 122. Specifically, the dust collection bucket guiding surface 122 may be formed with a protrusion moving hole, and the pushing protrusion 151 may be exposed to the outside after passing through the protrusion moving hole.

[0182] The pushing protrusion 151 may be disposed at a position where the coupling rod 222c can be pressed when the cleaner 200 is combined. That is, the coupling rod 222c may be disposed on the protrusion moving hole. And the coupling rod 222c may be disposed in the moving area of the pushing protrusion 151.

[0183] The pushing protrusion 151 can perform a linear reciprocating motion to press the coupling rod 222c. Specifically, the pushing protrusion 151 is coupled to the gear box 155 so that its linear movement is guided. The pushing protrusion 151 is coupled to the open lid gear 153, and thus can move together with the movement of the open lid gear 153.

[0184] The open lid motor 152 can provide the power to move the pushing protrusion 151. Specifically, the open lid motor 152 can rotate the motor shaft (not shown) forward or backward. Herein, the forward direction can refer to the direction in which the pushing protrusion 151 presses the coupling rod 222c. And the backward direction can refer to the direction in which the pushing protrusion 151 pressing the coupling rod 222c returns to its original position. The forward direction can be the direction opposite to the backward direction.

[0185] The open lid gear 153 is coupled to the open lid motor 152, and can move the pushing protrusion 151 by using the power of the open lid motor 152. Specifically, the open lid gear 153 can be accommodated inside the gear box 155. The drive gear 153a of the open lid gear 153 is coupled to the motor shaft of the open lid motor 152, and thus can receive power. The driven gear 153b of the open lid gear 153 is coupled to the pushing protrusion 151, and thus can move the pushing protrusion 151. As an example, the driven gear 153b is configured in a rack form, so as to engage with the drive gear 153a and can receive power from the drive gear 153a.

[0186] At this time, the discharge lid 222 can be provided with a torsion spring 222d. Due to the elastic force of the torsion spring 222d, the discharge lid 222 can rotate by more than a predetermined angle and be supported at the rotated position. Therefore, the discharge lid 222 can be opened, and the dust through hole 121a can be communicated with the inside of the dust collection bucket 220.

[0187] The gear box 155 is provided inside the housing 110, is disposed below the joint portion 120 in the direction of gravity, and the open lid gear 153 can be accommodated therein.

[0188] The gear box 155 can be provided with an open lid sensing portion 155f. At this time, the open lid sensing portion 155f can further include a contact sensor. As an example, the open lid sensing portion 155f can include a micro switch. On the other hand, the open lid sensing portion 155f can further include a non-contact sensor. As an example, the open lid sensing portion 155f can include an infrared sensor portion (IR sensor).

[0189] The open lid sensing portion 155f can be disposed on at least one of the inner side surface or the outer side surface of the gear box 155. As an example, one open lid sensing portion 155f can be disposed on the inner side surface of the gear box 155. At this time, the open lid sensing portion 155f can sense that the pushing protrusion 151 is in the initial position.

[0190] As other examples, two lid-opening sensing parts 155f may also be arranged on the outer side surface of the gear box 155. At this time, the lid-opening sensing parts 155f can sense the initial position and the lid-opening position of the pushing protrusion 151.

[0191] Therefore, according to the present invention, through the lid-opening unit 150, the user can open the dust collecting bucket 220 without specifically opening the discharge lid 222 of the sweeper, thereby improving convenience.

[0192] Moreover, the discharge lid 222 is opened in a state where the sweeper 200 is combined with the sweeper workstation 100, so it has the effect of preventing dust from scattering.

[0193] On the other hand, refer to the following Figure 2 and Figure 10 to describe the dust collecting part 170.

[0194] The sweeper workstation 100 may include a dust collecting part 170. The dust collecting part 170 may be arranged inside the housing 110. The dust collecting part 170 may be arranged on the lower side in the gravity direction of the joint part 120.

[0195] As an example, the dust collecting part 170 may refer to a dust bag that collects the dust sucked from the inside of the dust collecting bucket 220 of the sweeper 200 by the dust collecting motor 191.

[0196] The dust collecting part 170 may be detachably combined with the housing 110.

[0197] Therefore, the dust collecting part 170 can be detached from the housing 110 and discarded, and a new dust collecting part 170 can be combined with the housing 110. That is, the dust collecting part 170 can be defined as a consumable part.

[0198] The dust bag may be configured to increase in volume when the suction force is generated by the dust collecting motor 191, and the dust is accommodated inside.

[0199] For this purpose, the dust bag may be formed of a material that allows air to pass through but does not allow impurities such as dust to pass through. As an example, the dust bag may be made of a non-woven fabric material and may have a hexahedron shape when the volume increases.

[0200] Therefore, the user does not need to tie up the bag capturing the dust, etc., so the convenience of the user can be improved.

[0201] In contrast, the dust bag can be formed of a permeable material. For example, the dust bag may include a cylindrical plastic (not shown). With this configuration, after sealing or joining the dust bag, it is possible to prevent dust or odors captured inside the dust bag from leaking outside the dust bag. At this time, the dust bag can be installed in the housing 110 through a dust bag case (not shown). As needed, the dust bag can be replaced through the dust bag case.

[0202] On the other hand, the suction flow path portion 180 will be described below with reference to Figure 2 and Figure 10 explain the suction flow path portion 180.

[0203] The cleaning machine workstation 100 may include a suction flow path portion 180.

[0204] Dust in the dust collection bucket 220 of the cleaning machine 200 can move to the dust collection portion 170 through the suction flow path portion 180.

[0205] The suction flow path portion 180 may connect the dust passage hole 121a formed in the joint surface 121a and the dust collection portion 170. One end of the suction flow path portion 180 may be connected to the dust passage hole 121a, and the other end may be connected to the dust collection portion 170. The suction flow path portion 180 may be disposed at the rear side of the joint surface 121. The suction flow path portion 180 may refer to the space between the dust collection bucket 220 of the cleaning machine 200 and the dust collection portion 170. The suction flow path portion 180 may be a space formed rearward from the dust passage hole 121a, and may be a flow path formed by bending downward from the dust passage hole 121a to allow the dust and air to flow.

[0206] Specifically, the suction flow path portion 180 may include a first suction flow path 181 that communicates with the internal space of the dust collection bucket 220 when the cleaning machine 200 is combined with the cleaning machine workstation 100 to open the dust passage hole 121a, and a second suction flow path 182 that communicates between the first suction flow path 181 and the capture space 1711 of the dust bag 171.

[0207] As an example, the first suction flow path 181 may be configured to be substantially parallel to the axis of the suction motor 214 or a virtual through line passing through the dust collection bucket 220. At this time, the axis of the suction motor 214 or the through line of the dust collection bucket 220 may pass through the first suction flow path 181.

[0208] At this time, the second suction flow path 182 may be formed at a predetermined angle with the first suction flow path 181. As an example, the first suction flow path 181 and the second suction flow path 182 may be formed at a right angle. With this configuration, it is possible to minimize the overall volume of the cleaning machine workstation 100.

[0209] On the other hand, the length of the first suction passage 181 can be shorter than or the same as that of the second suction passage 182. With this configuration, even if the overall passage for removing dust is formed in a shape that bends once, the suction force of the dust collection motor 191 can be transmitted to the space inside the dust collection bin 220.

[0210] On the other hand, hereinafter, refer to Figure 2 and Figure 10 to describe the dust suction module 190.

[0211] The cleaning machine workstation 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191, a first filter 192, and a second filter (not shown).

[0212] The dust collection motor 191 may be disposed below the dust collection unit 170. The dust collection motor 191 may generate suction force in the suction passage unit 180. Thus, the dust collection motor 191 can provide a suction force capable of inhaling dust into the dust collection bin 220 of the cleaning machine 200.

[0213] The dust collection motor 191 may generate suction force by rotation. As an example, the dust collection motor 191 may be formed in a shape similar to a cylinder.

[0214] On the other hand, in the present embodiment, a virtual dust collection motor axis extending the rotation axis of the dust collection motor 191 may be formed.

[0215] The first filter 192 may be disposed between the dust collection unit 170 and the dust collection motor 191. The first filter 192 may be a pre-filter. The air that has passed through the first filter 192 may flow to the internal space housing the dust collection motor 191.

[0216] The second filter (not shown) may be disposed between the dust collection motor 191 and the outer wall surface 112. The second filter (not shown) may be a high-efficiency (HEPA) filter.

[0217] On the other hand, the cleaning machine workstation 100 may further include a charging unit 128. The charging unit may be disposed at the coupling unit 120. The charging unit 128 may be electrically connected to the cleaning machine 200 coupled to the coupling unit 120. The charging unit 128 may supply power to the battery of the cleaning machine 200 coupled to the coupling unit 120.

[0218] In addition, the cleaning machine workstation 100 may further include a side door (not shown). The side door may be disposed on the housing 110. The side door may selectively expose the dust collection unit 170 to the outside. Thus, the user can easily remove the dust collection unit 170 from the cleaning machine workstation 100.

[0219] Further, the sweeper workstation 100 may further include an exhaust port (not shown). The exhaust port (not shown) may be formed on the housing 110. For example, the exhaust port may be formed on the lower side of the housing 110 and connected to the dust collection motor 191 through a flow path. Therefore, the air that has passed through the dust collection motor 191 can be discharged to the outside of the housing 110 through the exhaust port.

[0220] Figure 11 A perspective view for explaining a fixing part and a bypass flow path in a sweeper workstation according to an embodiment of the present invention is shown. Figure 12 A front view for explaining a fixing part and a bypass flow path in a sweeper workstation according to an embodiment of the present invention is shown. Figure 13 A side view for explaining a fixing part and a bypass flow path in a sweeper workstation according to an embodiment of the present invention is shown. Figure 14 A view for explaining the fixing part in a state where the operation of the dust collection motor is ended is shown. Figure 15 A view for explaining the fixing part in a state where the dust collection motor is operating is shown.

[0221] Next, with reference to Figures 11 to 15 the fixing part 300 according to the present invention will be described.

[0222] The sweeper workstation 100 of the present invention may include a fixing part 300. The fixing part 300 may be disposed on the side wall 124. And at least a part of the fixing part 300 may be disposed on the back surface of the joint surface 121.

[0223] The fixing part 300 may fix the sweeper 200 coupled to the joint surface 121. Specifically, the fixing part 300 may fix the dust collection bucket 220 and / or the battery housing 230 of the sweeper 200 coupled to the joint surface 121.

[0224] The fixing part 300 may include a fixing member 310 for fixing the dust collection bucket 220 and the battery housing 230 of the sweeper 200 and a hinge member 320 for rotatably coupling the fixing member 310 to the coupling part 120.

[0225] The fixing member 310 is disposed on the side wall 124 of the coupling part 120 and may be configured to move back and forth on the side wall 124 to fix the dust collection bucket 220. Specifically, the fixing member 310 may be configured to be received inside the fixing member access hole 127 and rotate back and forth between the inside and outside of the side wall 124.

[0226] The fixing members 310 may be respectively disposed on both sides of the coupling part 120. As an example, the fixing members 310 may be symmetrically disposed in pairs with the joint surface 121 as the center.

[0227] On the other hand, the fixing member 310 may include a first pressing surface 310a, a second pressing surface 310b, and a moving seal 310c.

[0228] The first pressing surface 310a is formed at one end of the fixing member 310. In order to fix the dust collecting bucket 220 and / or achieve airtightness for the dust collecting bucket 220, it may be formed in a shape corresponding to the outer surface of the dust collecting bucket 220. As an example, the first pressing surface 310a may be formed in a shape that can wrap around a cylinder. The first pressing surface 310a may refer to a concave arc shape formed at one end of the fixing member 310.

[0229] The second pressing surface 310b is connected to the first pressing surface 310a. In order to fix the battery case 230 and / or achieve airtightness for the battery case 230, it may be formed in a shape corresponding to the shape of the battery case 230. As an example, the second pressing surface 310b may be formed in a shape that can press the battery case 230. That is, the second pressing surface 310b may refer to a linear shape formed at one end of the fixing member 310.

[0230] The moving seal 310c is disposed at the front end in the rotation direction of the fixing member 310 and can achieve airtightness for the dust collecting bucket 220 and / or the battery case 230. Specifically, the moving seal 310c is coupled to the first pressing surface 310a. When the first binding surface wraps around and presses the dust collecting bucket 220, the space between the dust collecting bucket 220 and the first pressing surface 310a can be sealed. Also, the moving seal 310c is coupled to the second pressing surface 310b. When the second pressing surface 310b presses the battery case 230, the space between the battery case 230 and the second pressing surface 310b can be sealed.

[0231] The fixing portion 300 may further include a hinge member 320 that rotatably couples the fixing member 310 to the coupling portion 120.

[0232] The fixing member 310 can rotate back and forth around the hinge member 320.

[0233] As an example, the hinge member 320 may rotatably couple the lower end of the fixing member 310 to the inner lower end of the side wall 124. Therefore, the fixing member 310 passing through the fixing member access hole 127 of the side wall 124 can rotate back and forth inside and outside the side wall 124 around the hinge member 320.

[0234] The fixing member 310 can move from the outside of the dust collecting bucket 220 to the dust collecting bucket 220 by the suction force (negative pressure) generated by the dust collecting motor 191. Specifically, the fixing member 310 can rotate from the outside of the dust collecting bucket 220 toward the dust collecting bucket 220 by the suction force generated by the dust collecting motor 191.

[0235] That is, when the dust collecting motor 191 operates, the fixing member 310 can rotate around the hinge member 320 from the outside of the dust collecting bucket 220 towards the direction approaching the dust collecting bucket 220 ( Figure 15 the clockwise direction in

[0236] ) to fix the dust collecting bucket 220.

[0237] Therefore, when the main body 210 of the cleaner 200 is disposed at the coupling part 120, the fixing member 310 can press and fix the dust collecting bucket 220 and / or the battery case 230 of the cleaner 200.

[0238] At this time, when the coupling sensor 125 senses the coupling of the cleaner 200 and the coupling part 120, the dust collecting motor 191 operates to rotate the fixing member 310, thereby fixing the cleaner 200.

[0239] Moreover, the dust collecting motor 191 can start operating before or simultaneously with the opening of the dust passage hole 121a. As an example, if the dust collecting motor 191 starts operating before a predetermined time when the dust passage hole 121a is opened and the fixing member 310 fixes the cleaner 200, the door motor 142 starts rotating forward, and while the door 141 rotates, the dust passage hole 121a can be opened. Figure 14

[0240] And when the operation of the dust collecting motor 191 ends, the fixing member 310 can rotate around the hinge member 320 in the direction away from the dust collecting bucket 220 ( Figure 14 the counterclockwise direction in ) due to the weight of the fixing member 310 itself.

[0241] At this time, the center of gravity G of the fixing member 310 can be located outside the rotation center of the fixing member 310 with respect to the dust collecting bucket 220. Here, the rotation center of the fixing member 310 can refer to a predetermined position on the hinge member 320.

[0242] At this time, when the dust collecting motor 191 does not operate, the fixing member 310 rotates in the direction of the center of gravity G with respect to the above rotation center ( Figure 14 the counterclockwise direction in

[0243] Also, when the dust collection motor 191 is not operating and thus the suction force is not transmitted to the fixing member 310, the fixing member 310 rotates away from the dust collection bin 220 about the hinge member 320 ( Figure 14 in the counterclockwise direction in), and the center of gravity G of the fixing member 310 further inclines outward. At this time, the fixing member 310 inserted inside the side wall 124 can rotate until it is supported by the side wall 124, and the rotatable angle of the fixing member 310 can be adjusted by other limiters or the like.

[0244] Moreover, when the cleaner 200 is coupled to the coupling part 120, the horizontal distance between the dust collection bin central axis C and the center of gravity G of the fixing member 310 can be longer than the horizontal distance between the dust collection bin central axis C and the rotation center of the fixing member 310. At this time, the above-mentioned horizontal distance can refer to the shortest distance in the horizontal direction.

[0245] Specifically, based on the state where the cleaner workstation 100 is placed on a flat ground, when the cleaner 200 is coupled to the coupling part 120, the horizontal distance between the dust collection bin central axis C and the center of gravity G of the fixing member 310 and the horizontal distance between the dust collection bin central axis C and the rotation center of the fixing member 310 can be arranged side by side with the ground.

[0246] On the other hand, referring to Figures 11 to 15 , the bypass flow path 500 according to the present invention will be described below.

[0247] The cleaner workstation 100 of the present invention may include a bypass flow path 500. The bypass flow path 500 can transmit the suction force (negative pressure) generated in the dust collection motor 191 to the fixing member 310. That is, when the dust collection motor 191 is operating, the suction airflow flowing along the bypass flow path 500 is discharged through one end 500a of the bypass flow path 500, thereby pulling the fixing member 310.

[0248] The bypass flow path 500 is disposed inside the housing 110, and the suction airflow generated by the dust collection motor 191 can flow therein.

[0249] At this time, one end 500a of the bypass flow path 500 can be connected to the coupling part 120. As an example, one end 500a of the bypass flow path 500 can be connected to the inner lower end of the side wall 124. As other examples, one end 500a of the bypass flow path 500 can be connected to the dust collection bin guiding surface 122. As another example, one end 500a of the bypass flow path 500 can be connected to the space between the side wall 124 and the dust collection bin guiding surface 122.

[0250] Moreover, the open side end 500a of the bypass flow path 500 can be configured to face the inner side surface of the fixing member 310. Thus, the suction airflow discharged through the side end 500a of the bypass flow path 500 after being generated by the dust collection motor 191 can cause the fixing member 310 to rotate in the direction approaching the dust collection bucket 220 ( Figure 15 clockwise direction in

[0251] The other side end 500b of the bypass flow path 500 can be connected to the dust collection unit 170 or the dust suction module 190. As an example, the other side end 500b of the bypass flow path 500 can be connected to the inside of the dust bag of the dust collection unit 170. As other examples, the other side end 500b of the bypass flow path 500 can be connected to the inside of the space housing the above-mentioned dust bag. As another example, the other side end 500b of the bypass flow path 500 can be connected to the inside of the space housing the dust collection motor 191.

[0252] On the other hand, in the state where the cleaner 200 is coupled to the coupling part 120, the side end 500a of the bypass flow path 500 can be located inside the fixing member 310. Specifically, the side end 500a of the bypass flow path 500 can be located closer to the dust collection bucket 220 than the fixing member 310.

[0253] Moreover, the rotation center of the fixing member 310 can be located between the side end 500a of the bypass flow path 500 and the center of gravity G of the fixing member 310. That is, when the suction force generated by the dust collection motor 191 is transmitted to the fixing member 310, the fixing member 310 can rotate in the direction approaching the side end 500a of the bypass flow path 500 with the hinge member 320 as the center ( Figure 15 clockwise direction in

[0254] At this time, when the rotation center of the fixing member 310 is located between the side end 500a of the bypass flow path 500 and the center of gravity G of the fixing member 310 in the state where the suction force generated by the dust collection motor 191 is transmitted to the fixing member 310, the fixing member 310 rotates in the direction approaching the dust collection bucket 220 with the hinge member 320 as the center ( Figure 15 clockwise direction in

[0255] Therefore, if the cleaner 200 is in the state of being coupled to the coupling part 120, the fixing member 310 can press and fix the cleaner 200.

[0256] The fixed seal 330 can be arranged on the dust collection bucket guiding surface 122 so as to achieve airtightness for the dust collection bucket 220 when the sweeper 200 is combined. With this configuration, when the dust collection bucket 220 of the sweeper 200 is combined, due to the self-weight of the sweeper 200, the fixed seal 330 can be pressurized, and the dust collection bucket 220 and the dust collection bucket guiding surface 122 can be sealed.

[0257] The fixed seal 330 can be arranged on the virtual extension line of the fixed part 310. With this configuration, when the dust collection motor 191 operates to pressurize the dust collection bucket 220 by the fixed part 310, the edge at the same height of the dust collection bucket 220 can be sealed.

[0258] According to an embodiment, corresponding to the configuration of the lid opening unit 150, the fixed seal 330 can be arranged on the dust collection bucket guiding surface 122 in a bent linear shape.

[0259] On the other hand, Figure 10 A block diagram showing a control configuration in a sweeper system according to an embodiment of the present invention is shown.

[0260] Referring to Figure 10 , the control configuration of the sweeper system 10 of the present invention will be described below.

[0261] The sweeper system 10 according to an embodiment of the present invention may further include a control unit 400 for controlling the coupling unit 120, the door unit 140, the lid opening unit 150, the dust collection unit 170, the suction flow path unit 180, the dust suction module 190, the suction motor 214, the operation unit 218, the battery 240, and the fixing unit 300.

[0262] The control unit 400 may be composed of a circuit board and components mounted on the above circuit board.

[0263] The control unit 400 may be divided into a workstation control unit 401 for controlling the sweeper workstation 100 and a sweeper control unit 402 for controlling the sweeper 200. The workstation control unit 401 and the sweeper control unit 402 may communicate with each other to exchange information or process data. Hereinafter, without special limitation, the workstation control unit 401 and the sweeper control unit 402 are collectively referred to as the control unit 400.

[0264] When the coupling sensor 125 senses the coupling of the sweeper 200, the coupling sensor 125 may send a signal that the sweeper 200 is coupled to the coupling unit 120. At this time, the control unit 400 receives the signal of the coupling sensor 125 and may determine that the sweeper 200 is coupled to the coupling unit 120.

[0265] Also, when the charging unit 128 supplies power to the battery 240 of the cleaner 200, the control unit 400 can determine that the cleaner 200 is coupled to the coupling part 120.

[0266] When it is determined that the cleaner 200 is coupled to the coupling part 120, the control unit 400 starts the dust collection motor 191 to rotate the fixing part 300.

[0267] When the fixing member 310 moves to a predetermined fixing location, the fixing sensing unit can send a signal indicating that the cleaner 200 is fixed. The workstation control unit 400 receives the signal indicating that the cleaner 200 is fixed from the above-mentioned fixing sensing unit, and can determine that the cleaner 200 is fixed. Specifically, when the workstation control unit 400 receives the signal indicating that the dust collection bin 220 is fixed from the above-mentioned fixing sensing unit, it starts the door motor 142 to operate forward, and when the door 141 rotates, it can open the dust passage hole 121a.

[0268] When the control unit 400 determines that the cleaner 200 is fixed to the coupling part 120, it can start the door motor 142 to open the door 141 of the cleaner workstation 100.

[0269] The door switch sensing unit 144 can send a signal indicating that the door 141 is opened when the door 141 or the door arm 143 reaches a predetermined open position. After the control unit 400 receives the signal indicating that the door 141 is opened from the door switch sensing unit 144, it can determine that the door 141 is opened. After the control unit 400 determines that the door 141 is opened, it can stop the operation of the door motor 142.

[0270] On the other hand, when the control unit 400 finishes emptying the dust collection bin 220, it can reverse the rotation of the door motor 142 to close the door 141.

[0271] When the control unit 400 determines that the door 141 is opened, it can start the lid opening motor 152 to open the discharge lid 222 of the cleaner 200.

[0272] The lid opening sensing unit 155f can send a signal indicating that the discharge lid 222 is opened when the guide frame 151e reaches a predetermined open position. After the control unit 400 receives the signal indicating that the discharge lid 222 is opened from the lid opening sensing unit 155f, it can determine that the discharge lid 222 is opened. After the control unit 400 determines that the discharge lid 222 is opened, it can stop the operation of the lid opening motor 152.

[0273] The control unit 400 can drive the dust collection motor 191 to suck the dust inside the dust collection bin 220.

[0274] The control unit 400 can start the display unit 410 to display the status of emptying the dust collection bin of the cleaner 200 and the charging status.

[0275] On the other hand, the cleaning machine workstation 100 of the present invention may include a display unit 410.

[0276] The display unit 410 may be disposed on the housing 110, or may be disposed on a separate display device, and may be provided in a terminal device including a mobile phone.

[0277] The display unit 410 may be configured to include at least one of a display panel capable of outputting text and / or graphics, and a speaker capable of outputting a sound signal and sound. Through the information output by the display unit, the user can easily understand the status of the ongoing process, the remaining time, etc.

[0278] On the other hand, the cleaning machine workstation 100 according to an embodiment of the present invention may include a memory 430. The memory 430 may include various data for the driving and operation of the cleaning machine workstation 100.

[0279] On the other hand, the cleaning machine workstation 100 according to an embodiment of the present invention may include an input unit 440. The input unit 440 generates key input data input by the user to control the operation of the cleaning machine workstation 100. To this end, the input unit 440 may be composed of a keyboard (key pad), a dome switch, a touch pad (resistive / capacitive), etc. In particular, when the touch pad and the display unit 410 form a layered structure with each other, it may be referred to as a touch screen.

[0280] As described above, the present invention has been described in detail through specific embodiments. However, these are for explaining the present invention, and the present invention is not limited to these embodiments. Those skilled in the art to which the present invention pertains may make variations or improvements to the present invention.
