Description

Technical Field

[0001] The present invention relates to a sweeper workstation, and more particularly, to a sweeper workstation that can automatically open or close the dust collection bucket lid of a sweeper when the sweeper is combined to collect the dust in the dust collection bucket. Background Art

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

[0003] Such sweepers can be divided into a manual sweeper in which the user directly moves the sweeper while cleaning and an automatic sweeper that performs cleaning while autonomously traveling. According to the type of sweeper, the manual sweeper can be divided into a horizontal sweeper, an upright sweeper, a handheld sweeper, a pole sweeper, etc.

[0004] In household sweepers, in the past, most used horizontal sweepers, but recently, there has been a trend of mostly using handheld sweepers and pole sweepers that have improved usability through the integration of a dust collection bucket and a sweeper body.

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

[0006] The handheld sweeper (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, etc.

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

[0008] However, in existing handheld sweepers and pole sweepers, the capacity of the dust collection bucket for storing the collected dust is small, so there is a trouble that the user needs to empty the dust collection bucket every time.

[0009] And when emptying the dust collection bucket, dust scatters, which poses a problem of harming the user's health.

[0010] And when the residual dust in the dust collection bucket cannot be removed, there is a problem of reducing the suction power of the sweeper.

[0011] In addition, when the residual dust in the dust collection bucket cannot be removed, there is a problem of foul odor caused by the residue.

[0012] As a prior patent document, Korean Patent Publication No. 10-2022-0086482 discloses a cleaning machine workstation that can automatically empty the dust collection bucket of the cleaning machine when the cleaning machine is combined.

[0013] The above prior patent document is configured such that when the cleaning machine is combined with the cleaning machine workstation, the discharge cover of the dust collection bucket of the cleaning machine is opened, and the dust passage hole is opened, thereby connecting the internal space of the dust collection bucket and the flow path of the cleaning machine workstation.

[0014] However, there is a problem in the above cleaning machine workstation that components such as an encoder for precisely sensing the rotation of the motor shaft need to be further provided for the precise rotation of the link rod.

[0015] In addition, the two link rods are fixedly coupled to be rotatable with respect to each other, so there is a problem that it is inconvenient when assembling a part of the link rod to the housing or when replacing a part of the link rod due to component breakage.

[0016] In addition, in the above cleaning machine workstation, a separate motor and sensor are provided to fix the dust collection bucket, and it takes time to start these components, so there is a problem of increasing the overall number of components and lengthening the total time required for dust collection. Summary of the Invention

[0017] Technical Problem to be Solved

[0018] The present invention is made to improve the problems of the existing cleaning machine workstation, cleaning machine system, and their control methods as described above, and an object thereof is to provide a cleaning machine workstation that can remove the dust in the dust collection bucket without additional operation by the user and can provide convenience to the user.

[0019] In addition, an object thereof is to provide a cleaning machine workstation that can automatically control the connection or disconnection of the discharge cover of the dust collection bucket to connect or disconnect the internal space of the dust collection bucket and the flow path of the cleaning machine workstation when the cleaning machine is combined.

[0020] In addition, an object thereof is to provide a cleaning machine workstation that can precisely start the motor and control the discharge cover even without using an encoder or the like.

[0021] In addition, an object thereof is to provide a cleaning machine workstation in which the assembly or replacement of the link rod is simple and the link rod can be prevented from falling off during the working process.

[0022] In addition, an object thereof is to provide a cleaning machine workstation that simplifies the process from when the cleaning machine is combined to when the dust collection motor starts to work, thereby reducing the total dust collection time.

[0023] Means for Solving the Technical Problem

[0024] To achieve the above object, the sweeper workstation according to the present invention includes: a housing; a coupling part configured in the housing, to which at least a part of the dust collecting bucket of the sweeper is coupled; a dust collecting bucket lid control unit for opening or closing the discharge lid of the dust collecting bucket; a dust collecting part accommodated inside the housing and disposed below the coupling part for capturing dust inside the dust collecting bucket; and a dust collecting motor accommodated inside the housing and disposed below the dust collecting part for generating a suction force to suck dust inside the dust collecting bucket. Among them, the dust collecting bucket lid control unit includes: a lid control motor; a link rod that rotates by the operation of the lid control motor; and a lid control frame that contacts the dust collecting bucket lid as the link rod rotates.

[0025] At this time, the lid control motor may be a synchronous motor.

[0026] In addition, a link rod stopper for restricting the rotation path of the link rod may be formed in the housing, and the link rod changes its rotation direction when it contacts the link rod stopper.

[0027] Thereby, even without an encoder, the link rod can be moved to an accurate position.

[0028] On the other hand, the link rod may include: a first link rod connected to the shaft of the lid control motor; and a second link rod rotatably coupled to the first link rod and coupled to the lid control frame.

[0029] At this time, the link rod stopper may be disposed within the rotation radius of the first link rod. Therefore, the first link rod contacts the link rod stopper, thereby being able to limit the rotation range of the first link rod.

[0030] A key hole may be formed in the second link rod, and a key protrusion coupled to the key hole may be formed in the first link rod. That is, the key hole of the second link rod and the key protrusion of the first link rod may be keyed. Therefore, separation is impossible when the first link rod and the second link rod are not disposed at a specific position.

[0031] On the other hand, the maximum length of the first link rod may be formed shorter than the maximum length of the second link rod.

[0032] And, the lid control frame may include: a frame body; a hinge part disposed on one side of the frame body and hinged to the housing; and a link rod coupling part disposed on the other side of the frame body and rotatably coupled to the second link rod, wherein the length from the hinge part to the link rod coupling part is shorter than the rotation radius of the second link rod.

[0033] Thus, even with a low-power lid control motor, the force to close the discharge lid of the dust collection bucket can be strengthened.

[0034] The first link rod may include a motor coupling portion for receiving the shaft of the lid control motor, and an induction protrusion is formed to protrude on the outer surface of the motor coupling portion. That is, a cam structure is introduced to the first link rod, so that the rotational position of the link rod can be sensed.

[0035] The dust collection bucket lid control unit may further include: a lid control sensor that senses when the link rod is in a predetermined position, and when the lid control sensor senses the link rod, the rotation of the link rod is stopped. Thus, the link rod can be precisely controlled.

[0036] The lid control sensor may be a microswitch.

[0037] Meanwhile, when the lid control sensor senses the link rod, the dust collection motor may be started.

[0038] On the other hand, regarding the operation of opening or closing the discharge lid of the dust collection bucket, when the rotation of the link rod is stopped, the dust collection motor is started, and when the operation of the dust collection motor ends, the link rod may rotate again. Thus, the discharge lid can be closed after the dust collection motor is started.

[0039] Advantages of the Invention

[0040] As described above, according to the cleaning machine workstation, the cleaning machine system, and their control methods of the present invention, there is an effect of being able to relieve the trouble for the user to empty the dust collection bucket every time.

[0041] And, there is an effect of being able to connect or cut off the flow path between the internal space of the dust collection bucket and the cleaning machine workstation by controlling the discharge lid while rotating the lid control frame when the cleaning machine is combined.

[0042] And, there is a cam-type link rod, and the cam is sensed by a microswitch, so that the rotational position of the link rod can be precisely sensed. Therefore, there is an effect of being able to precisely control the discharge lid even without using an encoder or the like.

[0043] And, through the bonding of the first link rod and the second link rod, there is an effect that the assembly or replacement between the link rods becomes easy and the link rods can be prevented from falling off during the working process.

[0044] And, when the cleaning machine is combined, the lid control frame is moved to open the discharge lid of the dust collection bucket and the dust collection motor is started, and when the operation of the dust collection motor ends, the discharge lid is closed. Therefore, there is an effect of being able to reduce the time required for the dust collection bucket to collect dust.

[0045] In addition, the time required to reduce the fixed sweeper or release the fixation of the sweeper is reduced, thereby having the effect of reducing the overall working time. Description of the Drawings

[0062] Figure 1 A perspective view of a sweeper system composed of a sweeper workstation and a sweeper according to an embodiment of the present invention is shown. Figure 5 A schematic diagram of the composition of a sweeper system according to various embodiments of the present invention is shown.

[0063] Referring to Figure 1 and Figure 5 , the sweeper system 10 according to an embodiment in this specification may include a sweeper workstation 100 and a sweeper 200.

[0064] The sweeper system 10 may include a sweeper workstation 100. The sweeper 200 may be coupled to the sweeper workstation 100. Specifically, the main body of the sweeper 200 may be coupled to the side of the sweeper workstation 100. The sweeper workstation 100 may remove the dust from the dust collection bucket 220 of the sweeper 200.

[0065] On the other hand, Figure 2 and Figure 3 A diagram for illustrating a sweeper in a sweeper system according to an embodiment of the present invention is shown. Figure 4 A diagram for illustrating the lower side of the dust collection bucket of a sweeper according to an embodiment of the present invention is shown.

[0066] First, the structure of the sweeper 200 will be described below with reference to Figures 1 to 5 the following.

[0067] The cleaning machine 200 may refer to a cleaning machine manually operated by a user. For example, the cleaning machine 200 may refer to a handheld cleaning machine or a pole-type cleaning machine.

[0068] The cleaning machine 200 can be placed at the cleaning machine workstation 100. The cleaning machine 200 can be supported by the cleaning machine workstation 100. The cleaning machine 200 can be integrated with the cleaning machine workstation 100.

[0069] On the other hand, in an embodiment of the present invention, the direction of the cleaning machine 200 can be defined based on when the bottom surface (lower side surface) of the dust collection bucket 220 and the battery housing 230 is placed on the ground.

[0070] At this time, the front can 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 can be called the right side, and the direction arranged on the left side is called the left side. And, in an embodiment of the present invention, based on when the bottom surface (lower side surface) of the dust collection bucket 220 and the battery housing 230 is placed on the ground, the upper side and the lower side can be defined in a direction perpendicular to the ground.

[0071] The cleaning machine 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.

[0072] The main body housing 211 may form the appearance of the cleaning machine 200. The main body housing 211 may provide a space for housing 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.

[0073] 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 (sometimes hereinafter referred to as "suction flow path") through which air including dust can flow.

[0074] On the other hand, in this embodiment, a virtual line penetrating the inside of the suction part 212 configured in a cylindrical shape may be formed.

[0075] The dust separation part 213 may communicate with the suction part 212. The dust separation part 213 may separate the dust sucked into the inside through the suction part 212. The space inside the dust separation part 213 may communicate with the space inside the dust collection bucket 220.

[0076] For example, the dust separation unit 213 may include at least one cyclone unit, and the cyclone unit may separate dust through cyclone flow. In addition, the space inside the dust separation unit 213 may communicate with the suction flow path. Therefore, the air and dust inhaled through the suction unit 212 may flow spirally along the inner surface of the dust separation unit 213. Therefore, a cyclone flow may be generated in the internal space of the dust separation unit 213.

[0077] 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 main body 210 through the suction unit 212.

[0078] The dust separation unit 213 may further include a secondary cyclone that separates dust from the air discharged from the cyclone again. At this time, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separation unit. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone may be distributed to the plurality of cyclone bodies to pass through.

[0079] At this time, the axis of the cyclone flow of the secondary cyclone may 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 may be coaxial in the vertical direction, and these may be collectively referred to as the axis of the cyclone flow of the dust separation unit 213.

[0080] The suction motor 214 may generate a suction force for inhaling air. The suction motor 214 may be housed in the main body housing 211. The suction motor 214 may generate a suction force by rotating. As an example, the suction motor 214 may be formed in a shape similar to a cylinder.

[0081] On the other hand, in the present embodiment, a virtual suction motor axis extending the rotation axis of the suction motor 214 may be formed.

[0082] The exhaust cover 215 may be disposed on one side in the axial direction of the main body housing 211. A filter for filtering air may be housed in the exhaust cover 215. As an example, a high-efficiency (HEPA) filter may be housed in the exhaust cover 215.

[0083] An exhaust port for discharging the air inhaled by the suction force of the suction motor 214 may be formed in the exhaust cover 215.

[0084] A flow guide may be disposed in the exhaust cover 215. The flow guide may guide the flow of the air discharged through the exhaust port.

[0085] The handle 216 can be held by a user. The handle 216 can be disposed 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 in a bent cylindrical shape. The handle 216 is disposed at a predetermined angle with respect to the main body housing 211, the suction motor 214, or the dust separation unit 213.

[0086] The handle 216 can include a grip portion formed in a columnar shape for a user to hold, a first extension portion connected to one end portion in the longitudinal direction (axial direction) of the grip 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 grip portion and extending toward the dust collection bin 220.

[0087] On the other hand, in the present embodiment, a virtual grip portion through-line extending in the longitudinal direction (axial direction of the column) of the grip portion and penetrating the grip portion can be formed.

[0088] As an example, the grip portion 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 grip portion.

[0089] 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.

[0090] The first extension portion can extend from the grip 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.

[0091] The second extension portion can extend from the grip portion toward the dust collection bin 220. At least a part of the second extension portion can extend in the horizontal direction.

[0092] The operation unit 218 can be disposed on the handle 216. The operation unit 218 can be disposed 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.

[0093] 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.

[0094] 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).

[0095] 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.

[0096] On the other hand, in the present embodiment, a virtual dust collection bucket central axis C that penetrates the inside (inner space) of the dust collection bucket main body 221 and extends in the length direction of the dust collection bucket main body 221 (referring to the axial direction in the cylindrical dust collection bucket main body 221) can be formed.

[0097] 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.

[0098] 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.

[0099] The discharge cover 222 can be set to open or close one end of the dust collection bucket main body 221 in the length direction. Specifically, the discharge cover 222 can selectively open or close the lower part of the dust collection bucket 220 that opens downward.

[0100] 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 case 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, 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 by the elastic force of the torsion spring 222d.

[0101] 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.

[0102] In the case of closing the discharge cover 222, the lower side surface of the dust collection bucket 220 can be blocked (sealed) by the discharge cover 222 and the lower surface extension part 221a.

[0103] The dust collecting bucket 220 may include a dust collecting bucket compression rod 223 (refer to Figure 3 ). The dust collecting bucket compression rod 223 may be disposed outside the dust collecting bucket 220 or the dust separation unit 213. The dust collecting bucket compression rod 223 may be disposed outside the dust collecting bucket 220 or the dust separation unit 213 in a vertically movable manner. The dust collecting bucket compression rod 223 may be connected to a compression member (not shown). When the dust collecting bucket 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 collecting bucket compression rod 223 may return to their original positions through an elastic member (not shown). Specifically, when the external force applied to the dust collecting bucket compression rod 223 is released, the elastic member may move the dust collecting bucket compression rod 223 and the compression member (not shown) upward.

[0104] The compression member (not shown) may be disposed inside the dust collecting bucket main body 221. The compression member may move within the internal space of the dust collecting bucket main body 221. Specifically, the compression member may move vertically within the dust collecting bucket main body 221. Thereby, the compression member may compress the dust inside the dust collecting bucket main body 221 downward. And, when the discharge cover 222 is detached from the dust collecting bucket main body 221 to open the lower part of the dust collecting bucket 220, the compression member moves from the upper part to the lower part of the dust collecting bucket 220, and impurities such as residual dust inside the dust collecting bucket 220 can be removed. Thereby, by avoiding residual dust remaining inside the dust collecting bucket 220, the suction force of the cleaner can be improved. Moreover, by avoiding residual dust remaining inside the dust collecting bucket 220, the malodor generated by the residue can be removed.

[0105] The cleaner 200 may include a battery housing 230. A 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 a hexahedron shape with an open lower part. The rear surface of the battery housing 230 may be connected to the handle 216.

[0106] The battery housing 230 may include a receiving portion that opens downward. The battery 240 may be loaded and unloaded through the receiving portion of the battery housing 230.

[0107] The cleaner 200 may include a battery 240.

[0108] For example, the battery 240 may be detachably coupled to the cleaner 200. The battery 240 may be detachably coupled to the battery housing 230. As an example, the battery 240 may be inserted into the inside of the battery housing 230 from below the battery housing 230. With this configuration, the portability of the cleaner 200 can be improved.

[0109] Differently, the battery 240 may be integrally provided inside the battery housing 230. At this time, the lower surface of the battery 240 is not exposed to the outside.

[0110] The battery 240 can supply power to the suction motor 214 of the sweeper 200. The battery 240 can be disposed below the handle 216. The battery 240 can be disposed behind the dust collection bin 220.

[0111] 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 sweeper 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.

[0112] 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 sweeper 200 can be reduced and weight reduction can be achieved.

[0113] The sweeper 200 may 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.

[0114] 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 force through the suction motor 214 and provide suction force 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.

[0115] The sweeper 200 may include a cleaning module 260. The cleaning module 260 can communicate with the extension tube 250. Accordingly, external air can flow into the main body 210 of the sweeper 200 through the cleaning module 260 and the extension tube 250 after being sucked by the suction force generated in the main body 210 of the sweeper 200.

[0116] The dust in the dust collection bin 220 of the sweeper 200 can be captured by the dust collection part 170 of the sweeper workstation 100 by gravity and the suction force of the dust collection motor 191. Thus, the dust in the dust collection bin can be removed without other operations by the user, so user convenience can be provided. Also, the trouble of emptying the dust collection bin by the user every time can be eliminated. And, when emptying the dust collection bin, dust scattering can be prevented.

[0117] The cleaning machine 200 can be coupled to the side of the housing 110. Specifically, the main body 210 of the cleaning machine 200 can be placed on the coupling part 120. More specifically, the dust collecting bucket 220 and the battery housing 230 of the cleaning machine 200 can be configured to face the coupling surface 121, the outer surface of the dust collecting bucket main body 221 can be coupled to the dust collecting bucket guiding surface 122, and the suction part 212 can be coupled to the suction part guiding surface 126 of the coupling part 120. In this case, the central axis of the dust collecting bucket 220 can be configured in a direction parallel to the ground, and the extension pipe 250 can be configured in a direction perpendicular to the ground.

[0118] Referring to Figure 1 and Figure 5 , the cleaning machine workstation 100 of the present invention will be described below.

[0119] The cleaning machine workstation 100 can be configured with a cleaning machine 200. The cleaning machine 200 can be coupled to the side of the cleaning machine workstation 100. Specifically, the main body of the cleaning machine 200 can be coupled to the side of the cleaning machine workstation 100. The cleaning machine workstation 100 can remove the dust from the dust collecting bucket 220 of the cleaning machine 200.

[0120] The cleaning machine workstation 100 can include a housing 110. The housing 110 can form the appearance of the cleaning machine 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.

[0121] Inside the housing 110, a space for accommodating a dust collecting part 170 for storing dust and a dust suction module 190 for generating a flow force for concentrating the dust in the dust collecting part 170 can be formed.

[0122] The housing 110 can include a bottom surface 111, an outer wall surface 112, and an upper surface 113.

[0123] 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 collecting motor 191 of the dust suction module 190.

[0124] 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 collecting motor 191 can be stably supported, and it has the advantage of being able to maintain the balance of the overall weight even when the cleaning machine 200 is coupled.

[0125] On the other hand, according to an embodiment, the bottom surface 111 may further include a ground supporting portion that increases the area of contact with the ground in order to prevent the cleaning machine workstation 100 from falling and maintain balance. As an example, the ground supporting 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 from the bottom surface 111 in the ground direction.

[0126] 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.

[0127] 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.

[0128] At this time, in this embodiment, the first outer wall surface 112a may be arranged on the front of the cleaning machine workstation 100. Herein, the front refers to the surface that exposes the cleaning machine 200 when the cleaning machine 200 is coupled to the cleaning machine workstation 100. Therefore, the first outer wall surface 112a may form the front appearance of the cleaning machine workstation 100.

[0129] On the other hand, to help understand this embodiment, the directions are defined as follows. In this embodiment, the directions may be defined when the cleaning machine 200 is placed on the cleaning machine workstation 100.

[0130] When the cleaning machine 200 is placed on the cleaning machine workstation 100, the direction in which the cleaning machine 200 is exposed outside the cleaning machine workstation 100 may be referred to as the front.

[0131] From another perspective, when the cleaning machine 200 is placed on the cleaning machine workstation 100, the direction in which the suction motor 214 of the cleaning machine 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 cleaning machine workstation 100 may be referred to as the rear.

[0132] In addition, based on the internal space of the housing 110, the surface facing the front direction may be referred to as the rear of the cleaning machine workstation 100. Therefore, the rear may refer to the direction in which the second outer wall surface 112b is formed.

[0133] In addition, based on the internal space of the housing 110, the left side surface when observing the above-mentioned front may be referred to as the left side, and the right side surface may be referred to as the right side. Therefore, the left side may refer to the direction in which the third outer wall surface 112c is formed, and the right side may refer to the direction in which the fourth outer wall surface 112d is formed.

[0134] The first outer wall surface 112a is formed in a planar shape, and it can also be integrally formed in a curved surface shape, or can be formed to include a curved surface locally.

[0135] The first outer wall surface 112a can have an appearance corresponding to the shape of the cleaning machine 200. Specifically, a 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 obtain the support of the cleaning machine workstation 100. The specific configuration of the coupling part 120 will be described later.

[0136] 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.

[0137] 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 or the second cleaning machine 300 is coupled. Therefore, the second outer wall surface 112b can form the appearance at the back of the cleaning machine workstation 100.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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 integrally formed in a curved surface shape, or can be formed to include a curved surface locally.

[0142] 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 third outer wall surface 112c or the fourth outer wall surface 112d.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] The upper surface 113 may be provided with a display unit 410. As an example, the display unit 410 may display the state of the cleaning machine workstation 100, the state of the cleaning machine 200, and in addition, may also display information such as the cleaning progress and the map of the cleaning area.

[0147] 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.

[0148] On the other hand, a link stopper 115 for restricting the rotation path of a link 143 described later may be formed on the housing 110. Specifically, the housing 110 may form a space flow path portion 180 inside through which air flowing in from the dust collection bucket 220 can flow, and the link stopper 115 may be formed to protrude on the inner wall surface of the pipe forming the flow path portion 180.

[0149] At this time, the link stopper 115 may be disposed within the rotation radius of the first link 1431.

[0150] Therefore, the first link 1431 contacts the link stopper 115, thereby restricting the rotation range of the first link 1431. Specifically, the link stopper 115 may include a first link stopper 115a that provides the lower rotation limit of the first link 1431 and a second link stopper 115b that provides the upper rotation limit of the first link 1431. With this configuration, the first link 1431 can rotate between the first link stopper 115a and the second link stopper 115b.

[0151] Therefore, according to the present invention, even without using an encoder or the like, the link 143 can be moved to an accurate position.

[0152] Figure 6 FIG. shows a diagram for explaining a joint portion in a cleaning machine workstation according to an embodiment of the present invention. Figure 7FIG. is 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 FIG. is 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 FIG. is 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.

[0153] Referring to Figure 5 and Figure 6 , the joint portion 120 of the cleaning machine workstation 100 of the present invention will be described below.

[0154] The cleaning machine workstation 100 may include a joint portion 120 for coupling the cleaning machine 200. Specifically, the joint portion 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 joint portion 120.

[0155] 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 be formed as a groove-shaped surface that is recessed from the first outer wall surface 112a toward the inside of the cleaning machine workstation 100. That is, the joint surface 121 may be a surface that forms a height difference with the first outer wall surface 112a.

[0156] The cleaning machine 200 may be received in the joint surface 121. As an example, the joint surface 121 may face the lower side surfaces of the dust collection bucket 220 and the battery housing 230 of the cleaning machine 200. Among them, the lower side surface may refer to the surface facing the ground when the user uses the cleaning machine 200 or places it on the ground.

[0157] As an example, the angle formed by the joint surface 121 and the ground may be a right angle. Thus, when the cleaning machine 200 is coupled to the joint surface 121, minimization of the space of the cleaning machine workstation 100 can be achieved.

[0158] As other examples, the joint surface 121 may be disposed at a predetermined angle inclined from the ground. Thus, when the cleaning machine 200 is coupled to the joint surface 121, the cleaning machine workstation 100 can be stably supported.

[0159] The joint surface 121 may be formed with a dust passage hole 121a so that air outside the housing 110 can flow into the inside. 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 portion 170. The dust passage hole 121a may be formed as a shape corresponding to the discharge lid 222 of the dust collection bucket 220. The dust passage hole 121a may be formed to communicate with a flow path portion 180 described later.

[0160] The joint portion 120 may include a dust collection bucket guiding surface 122. The dust collection bucket guiding surface 122 may be disposed on the first outer wall surface 112a. The dust collection bucket guiding surface 122 may be connected to the first outer wall surface 112a. Moreover, the dust collection bucket guiding surface 122 may be connected to the joint surface 121.

[0161] The dust collection bucket guiding surface 122 may be formed to correspond to the shape of the outer side surface of the dust collection bucket 220. The front outer side surface of the dust collection bucket 220 may be joined to the dust collection bucket guiding surface 122.

[0162] 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. Moreover, a gear box 155 for housing gears and the like of an opening / closing unit 150 described later may be provided below the dust collection bucket guiding surface 122 in the direction of gravity. At this time, a guiding space 122b in which the pushing protrusion 151 can move may be formed between the lower side surface of the dust collection bucket guiding surface 122 and the upper side surface of the gear box 155. In addition, the above-mentioned guiding space 122b may communicate with the first flow path portion 181 through a bypass hole 122c. That is, the protrusion moving hole 122a, the guiding space 122b, the bypass hole 122c, and the first flow path 181a may form a bypass flow path (refer to Figure 11 ). 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 joined to the joint portion 120, dust and the like remaining between the dust collection bucket 220 and the dust collection bucket guiding surface 122 can be sucked through the bypass flow path.

[0163] The joint portion 120 may include guiding protrusions 123. The guiding protrusions 123 may be disposed on the joint surface 121. The guiding protrusions 123 may protrude forward from the joint surface 121 toward the cleaning machine work station 100. 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 cleaning machine 200. Thereby, convenience in joining the cleaning machine 200 to the joint surface 121 can be provided.

[0164] The joint portion 120 may include side walls 124. The side walls 124 may refer to wall surfaces disposed on both side surfaces of the joint surface 121 and may be perpendicularly connected to the joint surface 121. The side walls 124 may be connected to the first outer wall surface 112a. Moreover, the side walls 124 may constitute a surface connected to the dust collection bucket guiding surface 122. Thereby, the cleaning machine 200 can be stably housed.

[0165] The joint portion 120 may include a joint sensor 125. The joint sensor 125 may sense whether the cleaning machine 200 is joined to the joint portion 120.

[0166] The coupling sensor 125 may also 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 guide protrusion 123. Therefore, when the battery housing 230 or the battery 240 of the sweeper 200 is coupled between the pair of guide protrusions 123, it contacts the coupling sensor 125, and the coupling sensor 125 may sense the coupling of the sweeper 200.

[0167] On the other hand, the coupling sensor 125 may also include a non-contact sensor. As an example, the coupling sensor 125 may include an infrared 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.

[0168] The coupling sensor 125 may face the dust collecting bin 220 or the battery housing 230 of the sweeper 200.

[0169] The coupling sensor 125 may be a means for determining whether power is applied to the battery 240 of the sweeper 200 and whether the sweeper 200 is coupled.

[0170] 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.

[0171] 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 131 can access.

[0172] With this configuration, 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. Thereby, convenience for coupling the dust collecting bin 220 and the battery housing 230 of the sweeper 200 to the coupling surface 121 can be provided.

[0173] Refer to Figure 5 、 Figure 7 and Figure 12 , the fixing unit 130 according to the present invention will be described below.

[0174] The cleaning machine workstation 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed on the side wall 124. The fixing unit 130 may fixedly engage with the cleaning machine 200 on the dust collection bucket guiding surface 122. Specifically, the fixing unit 130 may fixedly engage with the dust collection bucket 220 of the cleaning machine 200 on the dust collection bucket guiding surface 122.

[0175] The fixing unit 130 may include a fixing member 131 for fixing the dust collection bucket 220 and the battery housing 230 of the cleaning machine 200.

[0176] The fixing member 131 may be disposed on the side wall 124 of the engaging portion 120 and configured to be reciprocally movable on the side wall 124 to fix the dust collection bucket 220. Specifically, the fixing member 131 may be received inside the fixing member access hole 127.

[0177] The fixing members 131 may be respectively disposed on both sides of the engaging portion 120. As an example, two fixing members 131 are symmetrically disposed with the engaging surface 121 as the center to form a pair.

[0178] The fixing member 131 may move toward the dust collection bucket 220 when an external force is applied to fix the dust collection bucket. And when the external force is released, the fixing member 131 that fixes the dust collection bucket 220 may move away from the dust collection bucket 220.

[0179] As an example, the fixing member 131 may move by the power of a motor. That is, the fixing member 131 may receive power through at least one motor and a link rod connected to the motor to move.

[0180] As another example, the fixing member 131 may move by the suction force of the dust collection motor 191. That is, the fixing member 131 may move by receiving suction force through a flow path such as a hose.

[0181] On the other hand, the fixing unit 130 may further include a fixing seal 136. The fixing seal 136 may be disposed on the dust collection bucket guiding surface 122 to achieve airtightness for the dust collection bucket 220 when the cleaning machine 200 is engaged. With this configuration, when the dust collection bucket 220 of the cleaning machine 200 is engaged, due to the self-weight of the cleaning machine 200, the fixing seal 136 may be pressurized to seal the dust collection bucket 220 and the dust collection bucket guiding surface 122.

[0182] Thus, by avoiding residual dust remaining in the dust collection bucket, the suction force of the cleaning machine can be improved. Moreover, by avoiding residual dust remaining in the dust collection bucket, the odor generated by the residues can be removed.

[0183] Refer to Figure 5 、 Figures 8 to 10 and Figure 12, the dust collection bucket lid control unit 140 of the present invention will be described below.

[0184] The cleaning machine workstation 100 of the present invention may include a dust collection bucket lid control unit 140. The dust collection bucket lid control unit 140 may be configured to be able to open or close the dust passage hole 121a.

[0185] The dust collection bucket lid control unit 140 may include a lid control frame 141, a lid control motor 142, and a link rod 143.

[0186] The lid control frame 141 is hinged to the housing 110 and can open or close the dust passage hole 121a. The lid control frame 141 may include a frame body 141a.

[0187] The frame body 141a may be formed in a shape capable of blocking the dust passage hole 121a. As an example, the frame body 141a may be formed in a shape similar to a disc. As other examples, the frame body 141a may be formed in a quadrilateral plate shape.

[0188] Based on the state where the frame body 141a blocks the dust passage hole 121a, a hinge portion 141b may be disposed on the upper side of the frame body 141a, and a link rod coupling portion 141c may be disposed on the lower side of the frame body 141a.

[0189] The hinge portion 141b may be disposed at the upper end of the frame body 141a and is hinged to the housing 110.

[0190] The link rod coupling portion 141c may be a means for rotatably coupling the link rod 143. The link rod coupling portion 141c may be disposed on the lower side of the frame body 141a, and the link rod 143 is rotatably coupled to the link rod coupling portion 141c.

[0191] With this configuration, in a state where the lid control frame 141 blocks at least a part of the dust passage hole 121a, when the link rod 143 pulls the frame body 141a, the frame body 141a can rotate and move inwardly of the cleaning machine workstation 100 about the hinge portion 141b to open the dust passage hole 121a. On the other hand, in a state where the dust passage hole 121a is open, when the link rod 143 pushes the frame body 141a, the frame body 141a can rotate and move outwardly of the cleaning machine workstation 100 about the hinge portion 141b to block at least a part of the dust passage hole 121a.

[0192] On the other hand, in a state where the cleaning machine 200 is coupled to the cleaning machine workstation 100 and the discharge lid 222 is separated from the dust collection bucket main body 210, the lid control frame 141 may contact the discharge lid 222. In addition, as the lid control frame 141 rotates, the discharge lid 222 may rotate following the lid control frame 141.

[0193] The lid control motor 142 can provide power to rotate the lid control frame 141. Specifically, the lid control motor 142 can rotate the link 143 forward or backward.

[0194] Herein, forward can refer to the direction in which the link 143 pulls the lid control frame 141. Thus, when the link 143 rotates forward, the discharge lid 222 can be opened. Additionally, when the link 143 rotates forward, the internal space of the dust collection bucket 220 can communicate with the flow path portion 180.

[0195] And backward can refer to the direction in which the link 143 pushes the lid control frame 141. Thus, when the link 143 rotates backward, the discharge lid 222 can be closed. Additionally, when the link 143 rotates backward, the communication between the internal space of the dust collection bucket 220 and the flow path portion 180 can be cut off. Forward can be the direction opposite to backward.

[0196] The link 143 connects the lid control frame 141 and the lid control motor 142, and the lid control frame 141 can be opened or closed by using the power generated by the lid control motor 142.

[0197] As an example, the link 143 can include a first link 1431 and a second link 1432. One end portion of the first link 1431 can be coupled to the lid control motor 142. The first link 1431 can rotate by the power of the lid control motor 142. The other end portion of the first link 1431 can be rotatably coupled to the second link 1432. The first link 1431 can transmit the force transmitted from the lid control motor 142 to the second link 1432. One end portion of the second link 1432 can be coupled to the first link 1431. The other end portion of the second link 1432 can be coupled to the lid control frame 141. The second link 1432 pulls or pushes the lid control frame 141 to open or close the discharge lid 222.

[0198] The first link 1431 can include a first link main body 1431a, a motor coupling portion 1431b, an induction protrusion 1431c, and a key protrusion 1431d.

[0199] The first link main body 1431a can transmit the power of the lid control motor 142 to the second link 1432. For example, the first link main body 1431a is formed in a frame manner, with a motor coupling portion 1431b disposed on one side in the length direction, and a key protrusion 1431d can be formed on the other side in the length direction. Thus, the first link main body 1431a can be a rotating body that rotates about the motor coupling portion 1431b.

[0200] The motor coupling portion 1431b can be disposed on one side in the length direction of the first link main body 1431a.

[0201] The motor coupling part 1431b can be coupled to the cover control motor 142. For example, the motor coupling part 1431b can be directly coupled to the shaft of the cover control motor 142, or can be coupled through one or more gears (not shown). At this time, the motor coupling part 1431b can become the rotation axis of the first link 1431.

[0202] On the other hand, the motor coupling part 1431b can house at least a part of the cover control motor 142. For example, the motor coupling part 1431b can be formed in a cylindrical shape with one side blocked to house the shaft or gear of the cover control motor 142. With this configuration, when the cover control motor 142 operates, the motor coupling part 1431b can rotate.

[0203] On the other hand, induction protrusions 1431c can be formed to protrude on the outer surface of the motor coupling part 1431b. Two induction protrusions 1431c can be formed at a predetermined interval along the outer surface of the motor coupling part 1431b. That is, the first induction protrusion 1431ca and the second induction protrusion 1431cb can be formed to protrude at a predetermined interval along the outer surface of the motor coupling part 1431b. Therefore, with the rotation center of the motor coupling part 1431b as the reference, compared with the diameter to the outer surface of the motor coupling part 1431b, the diameter to the part where the induction protrusion 1431c is located can be larger. With this configuration, the motor coupling part 1431b and the induction protrusion 1431c can function as a kind of cam.

[0204] On the other hand, the induction protrusion 1431c can rotate integrally with the motor coupling part 1431b. That is, the induction protrusion 1431c can rotate following the rotation of the first link 1431.

[0205] As the first link 1431 rotates, the induction protrusion 1431c may come into contact with the cover control sensor 144. With this configuration, the induction protrusion 1431c can sense the rotation position (angle) of the first link 1431 through contact with the cover control sensor 144.

[0206] The first induction protrusion 1431ca can be configured to sense the position when the cover control frame 141 abuts against the discharge cover 222. In addition, the second induction protrusion 1431cb can be configured to sense the position of the cover control frame 141 when the discharge cover 222 is opened. For example, with the cover control frame 141 abutting against the discharge cover 222 as the reference, the first induction protrusion 1431ca can be disposed behind the second induction protrusion 1431cb in the cleaning machine work station. And with the discharge cover 222 being opened as the reference, the first induction protrusion 1431ca can be disposed below the second induction protrusion 1431cb.

[0207] On the other hand, the rotation of the link 143 can be restricted by the link stopper 115. That is, the first link 1431 can be blocked by the first link stopper 115a and the second link stopper 115b, so that its rotation is restricted. That is, the first link 1431 can stop rotating when it contacts the first link stopper 115a or the second link stopper 115b.

[0208] In addition, at the position where the first link 1431 is blocked by the first link stopper 115a, the first sensing protrusion 1431ca can contact the lid control sensor 144. And at the position where the first link 1431 is blocked by the second link stopper 115b, the second sensing protrusion 1431cb can contact the lid control sensor 144.

[0209] With this configuration, when the first link 1431 rotates to a preset position, the first link 1431 physically contacts the link stopper 115, so that its rotation is restricted. At the same time, the control unit 400 can sense the position of the first link 1431 and stop the operation of the lid control motor 142. Thus, the first link 1431 can rotate to an accurate position.

[0210] On the other hand, the key protrusion 1431d can be engaged with the keyhole 1432b formed in the second link 1432. The key protrusion 1431d can be formed on the other side in the length direction of the first link body 1431a.

[0211] The key protrusion 1431d can protrude from the first link body 1431a toward the surface of the second link 1432. At this time, the key protrusion 1431d can be formed to be capable of engaging with the second link 1432. For example, the key protrusion 1431d protrudes in a cylindrical shape and can protrude at least one or more protrusions from the outer surface toward the outside in the radial direction.

[0212] The second link 1432 can include a second link body 1432a, a keyhole 1432b, and a frame connection portion 1432c.

[0213] The second link body 1432a can transmit the power transmitted from the first link 1431 to the lid control frame 141. For example, the second link body 1432a is formed in a frame manner, a keyhole 1432b is formed on one side in the length direction, and the frame connection portion 1432c can be disposed on the other side in the length direction. Therefore, the second link body 1432a can be a rotating body that rotates about the key protrusion 1431d.

[0214] The keyhole 1432b may be formed on one side of the second link body 1432a. The keyhole 1432b may be formed to correspond to the shape of the key projection 1431d. For example, the keyhole 1432b may be formed in a circular hole shape and connected to a quadrilateral hole on the outer side in the radial direction. With this configuration, the key projection 1431d corresponds to the shape of the keyhole 1432b, so that they can be inserted and joined, thereby having the effect of preventing the first link 1431 and the second link 1432 from falling off each other when they rotate.

[0215] Therefore, according to the present invention, the key projection 1431d of the first link 1431 and the keyhole 1432b of the second link 1432 are bonded, so that the assembly or replacement between the first link 1431 and the second link 1432 becomes easy and the effect of preventing the first link 1431 and the second link 1432 from falling off during operation is achieved.

[0216] The frame connection part 1432c may be disposed on the other side in the length direction of the second link body 1432a.

[0217] The frame connection part 1432c may be combined with the cover control frame 141. The frame connection part 1432c may be hinged to the link connection part 141c. At this time, the hinge combining the frame connection part 1432c and the cover control frame 141 may become the rotation axis of the second link 1432.

[0218] On the other hand, in the present invention, the maximum length of the first link 1431 may be shorter than the maximum length of the second link 1432. And the maximum length of the first link 1431 may be shorter than the length from the hinge part 141b of the cover control frame 141 to the link connection part 141c. In addition, the length from the hinge part 141b of the cover control frame 141 to the link connection part 141c may be shorter than the rotation radius of the second link 1432 (more specifically, the length from the rotation center of the keyhole 1432b of the second link 1432 to the frame connection part 1432c).

[0219] With this configuration, in the state where the first link 1431 rotates about the motor connection part 1431b and the cover control frame 141 rotates about the hinge part 141b, the second link 1431 connecting the first link 1431 and the cover control frame 141 can apply a greater force during the process of pulling out the discharge cover 222.

[0220] That is, during the process of closing the discharge cover 222, as the first link 1431 rotates, the change in the rotation angle of the control frame 141 gradually increases. Therefore, it has the effect of strongly pulling the discharge cover 222 by increasing the rotation speed of the cover control frame 141.

[0221] More specifically, referring toFigure 15 When the first link 1431 with a predetermined length x rotates with a predetermined torque T1, a force F1 is transmitted to the second link 1432 along the wiring direction of the rotation locus of the first link 1431, and the force F1 is transmitted along the length direction of the second link 1432.

[0222] During this process, the angle θ1 between the direction of the force F1 applied by the first link 1431 and the length direction of the second link 1432 can be converted into a force F2 with which the second link 1432 presses the lid control frame 141.

[0223] Moreover, the force F2 with which the second link 1432 presses the lid control frame 141 can be transmitted to the lid control frame 141 along the length direction of the second link 1432 (F2 = F3).

[0224] The force F3 transmitted to the lid control frame 141 in this way can be converted again into a force Fc with which the lid control frame 141 closes the discharge lid 222 according to the angle θ2 between the second link 1432 and the lid control frame 141.

[0225] As a result, the force Fc with which the lid control frame 141 closes the discharge lid 222 can be greater than the force transmitted from the first link 1431 to the second link 1432. Therefore, there is an effect that even if the lid control motor 142 applies a torque of low power to the first link 1431, a force sufficient to close the discharge lid 222 can be generated.

[0226] Therefore, according to the present invention, the discharge lid 222 can be closed by using a motor of low power, so that there are effects of reducing the size of the motor, thereby reducing the volume and weight, and at the same time reducing the noise.

[0227] On the other hand, the dust collection bucket lid control unit 140 may further include a lid control sensor 144. The lid control sensor 144 may be provided inside the housing 110 and may sense whether the lid control frame 141 is in an open state.

[0228] For example, the lid control sensor 144 may be arranged at a position where it can contact the sensing protrusion 1431c. In addition, the lid control sensor 144 may be arranged at a position where it does not contact the outer surface of the motor coupling part 1431b. Therefore, when the lid control sensor 144 contacts the sensing protrusion 1431c as the first link 1431 rotates, the contact can be sensed.

[0229] Accordingly, when the first link 1431 rotates such that the first sensing protrusion 1431ca contacts the lid control sensor 144, the lid control sensor 144 can sense that the lid control frame 141 closes the dust collection bin 220. And when the first link 1431 rotates such that the second sensing protrusion 1431cb contacts the lid control sensor 144, the lid control sensor 144 can sense that the lid control frame 141 opens the discharge lid 222.

[0230] The lid control sensor 144 may include a contact sensor. As an example, the lid control sensor 144 may include a micro switch.

[0231] The lid control frame 141 may be opened together when the discharge lid 222 of the cleaner 200 is opened. And when the lid control frame 141 is closed, the discharge lid 222 of the cleaner 200 is also closed in linkage therewith.

[0232] When removing the dust from the dust collection bin 220 of the cleaner 200, the lid control motor 142 rotates the lid control frame 141 so that the discharge lid 222 can be coupled to the dust collection bin main body 221. Specifically, the lid control motor 142 rotates the first link 143, thereby rotating the lid control frame 141, and the rotating lid control frame 141 can push the discharge lid 222 toward the dust collection bin main body 221.

[0233] The following refers to Figure 5 、 Figure 11 and Figure 12 to describe the lid opening unit 150 of the present invention.

[0234] The cleaner workstation 100 of the present invention may include a lid opening unit 150. The lid opening unit 150 is disposed at the coupling part 120 and can open the discharge lid 222 of the cleaner 200.

[0235] The lid opening unit 150 may include a pushing protrusion 151, a lid opening motor 152, a lid opening gear 153, a support plate 154, and a gear box 155.

[0236] When the cleaner 200 is coupled, the pushing protrusion 151 can move in the manner of pressing the coupling rod 222c.

[0237] The pushing protrusion 151 may be disposed on the dust collection bin guide surface 122. Specifically, the dust collection bin guide surface 122 may be formed with a protrusion movement hole, and the pushing protrusion 151 may be exposed to the outside after passing through the protrusion movement hole.

[0238] The pushing protrusion 151 can be disposed at a position where it can press the coupling rod 222c when the sweeper 200 is coupled. That is, the coupling rod 222c can be disposed on the protrusion movement hole. And the coupling rod 222c can be disposed in the movement area of the pushing protrusion 151.

[0239] 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 gearbox 155, so that the linear movement is guided. The pushing protrusion 151 is coupled to the opening cover gear 153, so that it can move together with the movement of the opening cover gear 153.

[0240] The opening cover motor 152 can provide the power to move the pushing protrusion 151. Specifically, the opening cover motor 152 can rotate the motor shaft (not shown) forward or backward. Among them, the forward direction can refer to the direction in which the pushing protrusion 151 presses the coupling rod 222c. And the reverse 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 reverse direction.

[0241] The opening cover gear 153 is coupled to the opening cover motor 152, and can move the pushing protrusion 151 using the power of the opening cover motor 152. Specifically, the opening cover gear 153 can be accommodated inside the gearbox 155. The driving gear 153a of the opening cover gear 153 is coupled to the motor shaft of the opening cover motor 152, so that it can receive power. The driven gear 153b of the opening cover gear 153 is coupled to the pushing protrusion 151, so that the pushing protrusion 151 can be moved. As an example, the driven gear 153b is configured in a rack manner, so that it meshes with the driving gear 153a and can receive power from the driving gear 153a.

[0242] At this time, the discharge cover 222 can be provided with a torsion spring 222d. Due to the elastic force of the torsion spring 222d, the discharge cover 222 can rotate by more than a predetermined angle and be supported at the rotated position. Therefore, the discharge cover 222 can be opened, and the dust passage hole 121a can be communicated with the inside of the dust collection bucket 220.

[0243] The gearbox 155 is provided inside the housing 110, disposed on the lower side in the gravitational direction of the coupling part 120, and the opening cover gear 153 can be accommodated inside it.

[0244] The gearbox 155 can be provided with an opening cover sensing part 155f. At this time, the opening cover sensing part 155f can also include a contact sensor. As an example, the opening cover sensing part 155f can include a micro switch. On the other hand, the opening cover sensing part 155f can also include a non-contact sensor. As an example, the opening cover sensing part 155f can include an infrared sensor part (IR sensor).

[0245] The opening cover sensing unit 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 opening cover sensing unit 155f can be disposed on the inner side surface of the gear box 155. At this time, the opening cover sensing unit 155f can sense that the pushing protrusion 151 is located at the initial position.

[0246] As other examples, two opening cover sensing units 155f can also be disposed on the outer side surface of the gear box 155. At this time, the opening cover sensing unit 155f can sense the initial position and the opening position of the pushing protrusion 151.

[0247] Therefore, according to the present invention, through the opening cover unit 150, a user can open the dust collecting bucket 220 without specifically opening the discharge cover 222 of the first cleaner, thereby improving convenience.

[0248] Moreover, in a state where the cleaner 200 is combined with the cleaner workstation 100, the discharge cover 222 is opened, so there is an effect of preventing dust scattering.

[0249] On the other hand, refer to the following Figure 5 and Figure 12 to describe the dust collecting unit 170.

[0250] The cleaner workstation 100 can include a dust collecting unit 170. The dust collecting unit 170 can be disposed inside the housing 110. The dust collecting unit 170 can be disposed on the lower side in the gravitational direction of the coupling part 120.

[0251] As an example, the dust collecting unit 170 can refer to a dust bag that collects dust sucked from the inside of the dust collecting bucket 220 of the cleaner 200 by the dust collecting motor 191.

[0252] The dust collecting unit 170 can be detachably coupled to the housing 110.

[0253] Therefore, the dust collecting unit 170 can be detached from the housing 110 and discarded, and a new dust collecting unit 170 can be coupled to the housing 110. That is, the dust collecting unit 170 can be defined as a consumable part.

[0254] The dust bag can be configured such that when the suction force is generated by the dust collecting motor 191, the volume increases while dust is accommodated inside.

[0255] For this purpose, the dust bag can be formed of a material that allows air to pass through but does not allow dust and other impurities to pass through. As an example, the dust bag can be made of a non-woven fabric material and can have a hexahedron shape when the volume increases.

[0256] Therefore, a user does not need to tie a bag or the like capturing dust, so the convenience of the user can be improved.

[0257] In contrast, the dust bag may include a cylindrical plastic (not shown). With this configuration, after the dust bag is sealed or joined, it is possible to prevent dust or malodor captured inside the dust bag from leaking outside the dust bag. At this time, the dust bag may be installed in the housing 110 through a dust bag case (not shown). As needed, the dust bag may be replaced through the dust bag case.

[0258] On the other hand, the flow path unit 180 will be described below with reference to Figure 5 and Figure 12 explain the flow path unit 180.

[0259] The cleaning machine workstation 100 may include a flow path unit 180.

[0260] The flow path unit 180 may connect the dust collection bucket 220 of the cleaning machine 200 and the dust collection unit 170. The flow path unit 180 may be disposed at the rear side of the joint surface 121. The flow path unit 180 may refer to the space between the dust collection bucket 220 of the cleaning machine 200 and the dust collection unit 170. The flow path unit 180 may be a space formed rearward from the dust passage hole 121a and bent downward from the dust passage hole 121a so that dust and air can flow.

[0261] Specifically, it may include a first flow path 181 that is in communication with the internal space of the dust collection bucket 220 when the cleaning machine 200 is joined to the cleaning machine workstation 100 to open the dust passage hole 121a, and a second flow path 182 that communicates between the internal space of the first flow path 181 and the dust collection unit 170.

[0262] As an example, the first 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 flow path 181.

[0263] At this time, the second flow path 182 may be formed at a predetermined angle with respect to the first flow path 181. As an example, the first flow path 181 and the second 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.

[0264] The second flow path 182 extends downward from the first flow path 181 and communicates with the first flow path 181, so that air passing through the first flow path 181 can be guided to the dust collection unit 170.

[0265] The second flow path 182 may be disposed in a direction parallel to the axis C of the dust collection motor 191. With this configuration, it is possible to minimize the attenuation of the suction force of the dust collection motor 191 in the first flow path 181 and the second flow path 182.

[0266] Through the flow path unit 180, the dust in the dust collection bin 220 of the sweeper 200 can move to the dust collection unit 170.

[0267] On the other hand, refer to Figure 5 and Figure 12 to describe the dust suction module 190.

[0268] The sweeper workstation 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191, a first filter (not shown), and a second filter (not shown).

[0269] The dust collection motor 191 may be disposed below the dust collection unit 170. The dust collection motor 191 may generate a suction force in the flow path unit 180. Thus, the dust collection motor 191 can provide a suction force capable of sucking the dust in the dust collection bin 220 of the sweeper 200.

[0270] The dust collection motor 191 may generate a suction force by rotation. As an example, the dust collection motor 191 may be formed in a shape similar to a cylinder.

[0271] On the other hand, in the present embodiment, a virtual dust collection motor axis C extending the rotation axis of the dust collection motor 191 may be formed.

[0272] The first filter (not shown) may be disposed between the dust collection unit 170 and the dust collection motor 191. The first filter may be a pre-filter.

[0273] 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.

[0274] On the other hand, the sweeper 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 sweeper 200 coupled to the coupling unit 120. The charging unit 128 may supply power to the battery of the sweeper 200 coupled to the coupling unit 120.

[0275] In addition, the sweeper 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 simply remove the dust collection unit 170 from the sweeper workstation 100.

[0276] On the other hand, Figure 12 A block diagram for explaining the control configuration in the sweeper workstation according to an embodiment of the present invention is shown.

[0277] Refer to Figure 12, The control configuration of the sweeper workstation 100 of the present invention will be described below.

[0278] The sweeper workstation 100 according to an embodiment of the present invention may further include a control unit 400 for controlling the coupling unit 120, the fixing unit 130, the dustbin lid control unit 140, the lid opening unit 150, the dust collection unit 170, the flow path unit 180, and the dust suction module 190.

[0279] The control unit 400 may be composed of a circuit board and components mounted on the circuit board.

[0280] 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 from the coupling sensor 125 and may determine that the sweeper 200 is coupled to the coupling unit 120.

[0281] Moreover, when the charging unit 128 supplies power to the battery 240 of the sweeper 200, the control unit 400 may determine that the sweeper 200 is coupled to the coupling unit 120.

[0282] When it is determined that the sweeper 200 is coupled to the coupling unit 120, the control unit 400 activates the lid control motor 142 to open the lid control frame 141 of the sweeper workstation 100.

[0283] The lid control sensor 144 may send a signal that the lid control frame 141 is closed when it contacts the first sensing protrusion 1431ca. When the control unit 400 determines that the lid control frame 141 is closed, it may stop the operation of the lid control motor 142.

[0284] The lid control sensor 144 may send a signal that the lid control frame 141 is opened when it contacts the second sensing protrusion 1431cb. When the control unit 400 determines that the lid control frame 141 is opened, it may stop the operation of the lid control motor 142.

[0285] The lid opening sensing unit 155f may send a signal 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 that the discharge lid 222 is opened from the lid opening sensing unit 155f, it may determine that the discharge lid 222 is opened. After the control unit 400 determines that the discharge lid 222 is opened, it may stop the operation of the lid opening motor 152.

[0286] The control unit 400 may drive the dust collection motor 191 to suck the dust inside the dustbin 220.

[0287] The control unit 400 may activate the display unit 410 to display the status of emptying the dustbin of the sweeper 200 and the charging status.

[0288] On the other hand, the cleaning machine workstation 100 of the present invention may include a display unit 410.

[0289] The display unit 410 may be arranged on the housing 110, or may be arranged on a separate display device, and may be provided in a terminal device including a mobile phone.

[0290] 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.

[0291] 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.

[0292] 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. For this purpose, 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 are formed in a layered structure with each other, it may be referred to as a touch screen.

[0293] Figure 13 A flowchart for explaining the control method of the cleaning machine system according to the present invention is shown. Figure 14 A diagram showing the control of starting each motor in chronological order in the control method of the cleaning machine workstation according to an embodiment of the present invention is shown.

[0294] Refer to Figures 5 to 14 , and the control method of the cleaning machine workstation according to an embodiment of the present invention will be described below.

[0295] The control method of the cleaning machine workstation of the present invention includes a confirmation coupling step (S10), an open cover step (S20), an open cover step (S20), a collection step (S30), and a close cover step (S40).

[0296] In the confirmation coupling step (S10), it may be confirmed whether the cleaning machine 200 is coupled to the coupling portion 120 of the cleaning machine workstation 100.

[0297] Specifically, in the confirmation coupling step (S10), when the sweeper 200 is coupled to the coupling part 120, the coupling sensor 125 disposed on the guiding protrusion 123 may contact the battery housing 230, and the coupling sensor 125 may send a signal that the sweeper 200 is coupled to the coupling part 120. Alternatively, according to an embodiment, the presence of the dust collecting bin 220 may be sensed by the coupling sensor 125 of the non-contact sensor type disposed on the side wall 124, and the coupling sensor 125 may send a signal that the sweeper 200 is coupled to the coupling part 120.

[0298] Therefore, in the confirmation coupling step (S10), the control unit 400 receives the signal generated by the coupling sensor 125 and may determine that the sweeper 200 is coupled to the coupling part 120.

[0299] Alternatively, in the confirmation coupling step (S10) of the present invention, the control unit 400 may sense whether the sweeper 200 is coupled to the correct position according to whether the charging part 128 supplies power to the battery 240 of the sweeper 200.

[0300] In the open lid step (S20), when the dust collecting bin 220 is coupled to the sweeper workstation 100, the control unit 400 may open the discharge lid 222 of the sweeper 200.

[0301] When receiving the signal that the dust collecting bin 220 is fixed from the fixing sensing part 137, the control unit 400 may forwardly start the open lid motor 152 to open the discharge lid 222.

[0302] Specifically, the control unit 400 may forwardly drive the open lid motor 152. As a result, the pushing protrusion 151 is disengaged from the initial position and moves to the position of the pressing coupling rod 222c. Therefore, by the movement of the coupling rod 222c, the hook coupling between the discharge lid 222 and the dust collecting bin main body 221 is released, and by the restoring force of the torsion spring 222d, the discharge lid 222 rotates in a direction away from the dust collecting bin main body 221 and is thus disassembled.

[0303] On the other hand, before the pushing protrusion 151 presses the coupling rod 222c, the open lid sensing part 155f may send a signal that the pushing protrusion 151 is located at the initial position.

[0304] When the open lid motor 152 is started so that the pushing protrusion 151 starts to move to press the coupling rod 222c, the open lid sensing part 155f may send a signal that the pushing protrusion 151 has disengaged from the initial position. In addition, when the control unit 400 receives such a signal, it may determine that the open lid unit 150 is operating normally.

[0305] At this time, the control unit 400 may measure the time after forwardly driving the open lid motor 152 or measure the time after the pushing protrusion 151 disengages from the initial position through a timer (not shown).

[0306] At this time, in the control unit 400, the time required for the pushing projection 151 to move from the initial position until it presses the coupling lever 222c can be preset and stored based on the rotational speed of the lid-opening motor 152 and the moving distance of the pushing projection 151. Therefore, the control unit 400 can drive the lid-opening motor 152 forward during the lid-opening time tc1, where the lid-opening time tc1 is longer than the time required until the above-mentioned coupling lever 222c is pressed. As an example, the control unit 400 can drive the lid-opening motor 152 forward for a time period of 4 seconds or more and 5 seconds or less.

[0307] In addition, after the above-mentioned lid-opening time tc1 has elapsed, the control unit 400 can change the rotational direction of the lid-opening motor 152 during a preset rotational direction change time tc2.

[0308] In addition, after the above-mentioned rotational direction change time tc2 has elapsed, the control unit 400 can drive the lid-opening motor 152 in the reverse direction. As a result, the pushing projection 151 can return to the initial position again.

[0309] The control unit 400 can drive the lid-opening motor 152 until the lid-opening sensing unit 155f senses that the pushing projection 151 has returned to the initial position. At this time, the projection return time tc3 required for the pushing projection 151 to return to the initial position after pressing the coupling lever 222c can be preset and stored in the control unit 400. Therefore, the control unit 400 can drive the lid-opening motor 152 in the reverse direction during the projection return time tc3. As an example, the control unit 400 can drive the lid-opening motor 152 in the reverse direction for a time period of 4 seconds or more and 5 seconds or less.

[0310] On the other hand, when the control unit 400 receives a signal that the pushing projection 151 has returned to the initial position from the lid-opening sensing unit 155f, it can end the drive of the lid-opening motor 152.

[0311] On the other hand, in the lid-opening step (S20), the control unit 400 can open the lid control frame 141.

[0312] Specifically, when the control unit 400 receives a signal combined with the dust collection bin 220, it drives the lid control motor 142 forward to rotate the first link 1431 and lift it upward. At this time, the first link 1431 can lift one side of the second link 1432, and the other side of the second link 1432 lifts the lid control frame 141. As a result, the lid control frame 141 rotates and the dust passage hole 121a can be opened. That is, in the lid-opening step (S20), the control unit 400 can open the dust passage hole 121a by rotating the lid control frame 141.

[0313] On the other hand, in the present embodiment, when a preset time has elapsed after the control unit 400 receives the signal that the dust collection bucket 220 is combined, the lid control motor 142 can be started in the forward direction. As an example, when a time of 0.5 seconds or more and 1.5 seconds or less has elapsed after the dust collection bucket 220 is combined or after a user input operation, the control unit 400 can start the lid control motor 142.

[0314] With this configuration, in the lid opening step (S20), after waiting for the time required for the pushing protrusion 151 to start pressing the coupling rod 222c, the lid control frame 141 can be opened, so that the discharge lid 222 and the lid control frame 141 can be opened at approximately the same time. Therefore, it is possible to prevent the lid control frame 141 from rotating first to open the dust passage hole 121a and then the discharge lid 222 from suddenly opening due to the restoring force of the torsion spring 222d, resulting in a strong collision between the lid control frame 141 and the discharge lid 222, or it is impossible to open the lid control frame 141 even if the hook coupling between the discharge lid 222 and the dust collection bucket main body 221 is released, so that the discharge lid 222 and the dust collection bucket main body 221 cannot be separated.

[0315] As a result, after the lid opening step (S20) is performed, the discharge lid 222 of the dust collection bucket 220 rotates to open the space inside the dust collection bucket main body 221, and the lid control frame 141 rotates to open the dust passage hole 121a, whereby the internal space of the dust collection bucket 220 and the flow path unit 180 (specifically, the first flow path 181) of the cleaner workstation 100 can be communicated.

[0316] On the other hand, when the lid control sensor 144 senses the second sensing protrusion 1431cb, it can send a signal about this. Therefore, the control unit 400 can determine that the lid control frame 141 is opened and stop the operation of the lid control motor 142.

[0317] Differently, according to an embodiment, the control unit 400 can operate the lid control motor 142 for a preset time period. As an example, the control unit 400 can also drive the lid control motor 142 in the forward direction for a time period of 5 seconds or more and 7 seconds or less, and then stop the operation of the lid control motor 142.

[0318] Or, according to an embodiment, the control unit 400 can sense the load of the lid control motor 142 when the link rod 143 contacts the link rod stopper 115 and then stop the operation of the lid control motor 142.

[0319] In the collection step (S30), when the discharge lid 222 is opened and the lid control frame 141 rotates to open the dust passage hole 121a, the dust collection motor 191 is started to collect the dust inside the dust collection bucket 220.

[0320] As an example, in the collection step (S30), after the control unit 400 receives a signal that the lid control frame 141 is opened from the lid control sensor 144, it may start the operation of the dust collection motor 191. That is, in the collection step (S30), when the rotation of the link 143 stops, the dust collection motor 191 may be started.

[0321] As other examples, when the time elapsed after the dust collection bucket is combined or the user input operation is more than 6 seconds and less than 7 seconds, the control unit 400 may start the operation of the dust collection motor 191.

[0322] In the collection step (S30), the control unit 400 may start the dust collection motor 191 to rotate at a preset dust collection speed Ws for a preset dust collection time ts. As an example, in the collection step (S30), the control unit 400 may start the dust collection motor 191 to rotate at a preset dust collection speed Ws for a time period of more than 5 seconds and less than 9 seconds. However, it is not limited thereto, and the dust collection time may be changed according to the output of the dust collection motor 191 and the amount of dust stored inside the dust collection bucket 220.

[0323] According to the collection step (S30), the dust inside the dust collection bucket 220 may be collected in the dust collection part 170 after passing through the dust through hole 121a and the flow path part 180. Therefore, the user can remove the dust inside the dust collection bucket 220 without performing other operations, and thus has the effect of improving user convenience.

[0324] On the other hand, in the present invention, according to an embodiment, the fixing of the dust collection bucket 220 may be performed simultaneously in the collection step (S30). Specifically, in the collection step (S30), by the operation of the dust collection motor 191, the suction force of the dust collection motor 191 may start the fixing unit 130. That is, in the collection step (S30), by the suction force of the dust collection motor 191, the fixing member 131 may move in the direction of pressing the dust collection bucket 220.

[0325] With this configuration, even if there is a jitter in the sweeper workstation 100 due to the operation of the dust collection motor 191, the dust collection bucket 220 can be stably fixed.

[0326] Therefore, according to the present invention, the time required for fixing the sweeper 200 or releasing the fixing is reduced, thereby having the effect of reducing the overall working time.

[0327] On the other hand, the control method of the sweeper workstation according to an embodiment of the present invention may further include a lid closing step (S40) of rotating the lid control frame 141 to block the dust through hole 121a after the operation of the dust collection motor 191 ends. That is, in the lid closing step (S40), when the operation of the dust collection motor 191 ends, the link 143 may rotate again.

[0328] In the lid closing step (S40), the control unit 400 can operate the lid control motor 142 in a direction opposite to the operating direction of the lid control motor 142 in the lid opening step (S20).

[0329] Specifically, in the lid opening step (S20), the first link 1431 abuts against the second link stopper 115b, the lid control sensor 144 senses the second sensing protrusion 1431cb, and the operation of the lid control motor 142 operating in the forward direction stops. Thereafter, in the lid closing step (S40), the lid control motor 142 is started in the reverse direction.

[0330] That is, in the lid closing step (S40), the control unit 400 can reverse the rotation direction of the shaft of the lid control motor 142.

[0331] For example, after the control unit 400 finishes the operation of the dust collecting motor 191, it can start the lid control motor 142 in the reverse direction to rotate the lid control frame 141.

[0332] Specifically, after the control unit 400 finishes the operation of the dust collecting motor 191, it can start the lid control motor 142 in the reverse direction to rotate the first link 1431 downward. At this time, the first link 1431 can lower one side of the second link 1432, and the other side of the second link 1432 lowers the lid control frame 141. As a result, the lid control frame 141 rotates, so that the dust passage hole 121a can be closed. That is, in the lid closing step (S40), the control unit 400 rotates the lid control frame 141 to close the dust passage hole 121a.

[0333] At this time, when the lid control sensor 144 senses the first sensing protrusion 1431ca, it can send a signal regarding this. Therefore, the control unit 400 can determine that the lid control frame 141 has closed the dust passage hole 121a and can stop the operation of the lid control motor 142.

[0334] Differently, according to an embodiment, the control unit 400 can operate the lid control motor 142 for a preset time period. As an example, the control unit 400 can also stop the operation of the lid control motor 142 after operating the lid control motor 142 in the reverse direction for a time period of 5 seconds or more and 7 seconds or less.

[0335] Therefore, according to the present invention, without using an encoder or the like, when the first link 1431 is blocked by the link stopper 115, the control unit 400 then reverses the operating direction of the lid control motor 142, thereby having the effect of being able to accurately control the movement of the lid control frame 141 and controlling the discharge lid 222.

[0336] Moreover, according to the present invention, the moving cover controls the frame 141 to open the discharge cover 222 of the dust collection bin while starting the dust collection motor 191, and closes the discharge cover 222 while ending the operation of the dust collection motor 191, thereby having the effect of being able to reduce the time required for dust collection in the dust collection bin 220.

[0337] As described above, the present invention has been described in detail through specific embodiments. However, these are for illustrative purposes only, and the present invention is not limited to these embodiments. Those skilled in the art to which the present invention pertains can make variations or improvements to the present invention.

[0338] Simple variations and changes to the present invention all fall within the protection scope of the present invention, and the specific protection scope of the present invention is further clarified by the claims.
