Description

Technical Field

[0001] The present invention relates to a cleaning machine workstation and a dust collection method for the cleaning machine workstation. More specifically, the present invention relates to a cleaning machine workstation capable of sensing the rotation angle of a compression unit with high accuracy to calculate the amount of dust collected, capable of displaying a warning notification in multiple levels according to the calculated amount of dust collected, and a dust collection method using such a cleaning machine workstation. Background Art

[0002] In the case of a pole-type cleaning machine (hereinafter, referred to as a 'cleaning machine'), the dust canister that stores collected dust has a small capacity, and thus there is a trouble that the user needs to empty the dust canister every time.

[0003] In this regard, cleaning machine workstations constructed in the following manner are increasingly being used: dust in the dust canister is sucked in and captured by the suction force of a dust collecting motor, so that the user does not need to manually remove the dust in the dust canister.

[0004] Such a cleaning machine workstation includes a housing, a dust collecting motor disposed inside the housing, and a dust bag for storing captured dust, and is combined with a cleaning machine or a dust cylinder of the cleaning machine.

[0005] The convenience of the cleaning machine workstation is that it can automatically empty the dust barrel of the cleaning machine. Most of the dust bags included in the cleaning machine workstation are large in size compared to the dust barrel provided in the cleaning machine, so there is an advantage that the period required for dust processing is prolonged.

[0006] In addition, the dust bag is a consumable part. When the dust bag is full of dust, it needs to be replaced with a new one. This will cause the following problems: the inconvenience of periodic replacement, the scattering of dust generated during the separation process from the cleaning machine workstation due to the material characteristics of the dust bag, and the cost burden of periodically purchasing new dust bags.

[0007] In this regard, US Patent Publication No. 10595692 is disclosed as the first prior art patent.

[0008] In the first prior art patent, a discharge station including a bin-shaped canister dust cartridge and a dust separator is disclosed as an embodiment of the discharge station docked with the robot cleaning machine.

[0009] In one embodiment disclosed in the first prior art patent, the dust separator is formed into a conical shape and included inside the tank in order to utilize the principle of centrifugal separation. Another embodiment disclosed in the prior art patent document is formed in a structure in which dust separated from a multi-stage separation device arranged at the upper part of the tank is collected in the tank.

[0010] However, the dust cylinder disclosed in the first prior art patent always generates air flow inside the multi-stage separation device based on the centrifugal separation principle, thereby increasing the volume of captured dust, thereby causing a problem of reduced dust storage efficiency compared to the dust bag.

[0011] As a second prior art patent, Korean Patent Gazette No. 0906848 is disclosed.

[0012] The second prior art patent relates to a vacuum cleaner. The vacuum cleaner disclosed in the second prior art patent includes: a dust collecting unit that stores foreign matter; a pressure plate that is movably disposed in the dust collecting unit to compress the foreign matter; and a driving motor that moves the pressure plate.

[0013] Furthermore, the dust collecting unit further includes a display unit that displays a timing for clearing out the compressed foreign matter when the transfer range of the pressurizing plate is within a certain range.

[0014] According to the second prior art patent, the dust stored in the dust collecting unit is compressed, thereby having the advantage of improving the dust storage efficiency, but the emptying timing will be displayed on the display unit only when the dust is fully accumulated.

[0015] As in the second existing patent, even if the emptying time is displayed on the display only when the dust is full, if it is a cleaning machine, the dust barrel of the cleaning machine is mostly made of transparent material, and the user can easily grasp the dust storage amount. Therefore, before the dust barrel is full of dust, the dust can be emptied at the time desired by the user.

[0016] On the contrary, in the case of a cleaning machine workstation with a dust emptying function, most of them are covered with an opaque cover to prevent the dust capturing state of the dust capturing part from being exposed to the outside for aesthetic reasons. Therefore, there is the inconvenience that the user needs to directly take out the dust capturing part and check it with his eyes in order to confirm the extent of dust captured in the dust capturing part.

[0017] In addition, even if the emptying time is displayed on the display only when the dust is full as in the second existing patent, if it is a cleaning machine, as dust accumulates in the dust canister, the user can directly feel the degree of decrease in dust attraction during cleaning, so the user can empty the dust at a desired time before the dust fills up the dust canister.

[0018] On the contrary, in the case of a cleaning machine workstation with a dust emptying function, even if the force of sucking dust by the dust cylinder decreases, the user cannot directly feel this situation, and may miss the opportunity to remove dust from the dust capture part.

[0019] In addition, the second prior art patent describes that the rotation range of the pressure plate is detected to display the dust clearing timing, but a specific method for detecting the rotation range of the pressure plate is not disclosed.

[0020] Furthermore, in the second prior art patent, the pressure plate is rotated immediately after collecting the dust to compress the dust, and in the time until the dust is collected again, the compressed dust is scattered and the volume of the dust expands again. Summary of the invention

[0024] In addition, an object of the present invention is to provide a cleaning machine workstation and a dust collection method that improve convenience and allow a user to flexibly select a time to remove dust collected in a capture portion.

[0025] Another object of the present invention is to provide a cleaning machine station and a dust collection method that improve the accuracy when calculating the amount of dust collected in a capturing portion.

[0026] Means of solving technical problems

[0027] In order to achieve the above-mentioned purpose, the cleaning machine workstation of an embodiment of the present invention includes: a shell, which is combined with the dust barrel of the cleaning machine; a dust collecting motor, which is arranged inside the above-mentioned shell and generates an attraction force to suck the dust into the above-mentioned dust barrel; a capture part, which has a storage space, and the storage space collects the dust sucked from the inside of the above-mentioned dust barrel by the above-mentioned dust collecting motor; a compression part, which can be rotatably arranged inside the above-mentioned capture part and compress the collected dust; a compression motor, which is arranged outside the above-mentioned capture part and generates power for the above-mentioned compression part to rotate; a power transmission part, which is arranged between the above-mentioned compression part and the above-mentioned compression motor, and includes a driving gear that rotates using the power of the above-mentioned compression motor; and a compression state sensing part, which is arranged adjacent to the above-mentioned driving gear, and uses the shape formed on the above-mentioned driving gear to sense the rotation direction of the above-mentioned compression part and the rotation angle related to the above-mentioned rotation direction.

[0028] The power transmission part may further include a transmission gear connected to the compression part and meshed with the driving gear, and receiving the power of the compression motor from the driving gear and transmitting it to the compression part.

[0029] At this time, the transmission gear can be detachably attached to the housing in a state of being coupled to the capture portion.

[0030] The compression state sensing unit may be composed of a photo interrupter.

[0031] The compression part may include: a rotating shaft component, which is arranged in an up-and-down direction inside the capture part and rotated by the power of the compression motor; a fixed plate, which is fixedly arranged on one side inside the capture part; and a rotating plate, which is connected to the outer peripheral surface of the rotating shaft component and rotates together with the rotating shaft component.

[0032] The driving gear may include: a gear body, which forms the appearance of the driving gear; and a shaft connecting portion, which is arranged at the center of the gear body and connected to the motor shaft of the compression motor.

[0033] Here, the shape formed on the driving gear may be a pattern formed on the gear body.

[0034] In this case, the pattern is formed by protrusions and grooves being alternately continuous around the lower side of the gear body.

[0035] In addition, the pattern may be formed such that widths of the protrusions and widths of the grooves adjacent to each other are different from each other.

[0036] In addition, when the above-mentioned protrusion and the above-mentioned groove are defined as phases divided according to the size of the width formed, the above-mentioned pattern is formed so that the arrangement order of the above-mentioned phases is different from each other relative to a first direction and a second direction related to the periphery of the above-mentioned gear body, wherein the second direction is a direction opposite to the above-mentioned first direction.

[0037] The cleaning machine workstation according to an embodiment of the present invention may further include a control unit configured to calculate the amount of dust captured by the capturing unit.

[0038] Here, when the protrusion and the groove are defined as phases divided according to the size of the formed width, the control unit calculates the rotation angle based on the number of changes of the phase sensed by the compression state sensing unit.

[0039] The capture section includes: a dust collecting space, which receives and stores the sucked dust and is provided with the compression section; a grid net, which is provided on one side of the dust collecting space; and a plurality of cyclone separation sections, which filter dust from the air flowing from the dust collecting space through the grid net.

[0040] Here, the mesh net is formed by a part of a wall surface defining the dust collection space.

[0041] In order to achieve the above-mentioned purpose, a cleaning machine system of one embodiment of the present invention may include: a cleaning machine, which includes a dust cylinder for capturing dust; a cleaning machine workstation, which is combined with the above-mentioned cleaning machine to remove dust inside the above-mentioned dust cylinder; and a display device, which visually displays driving information related to the operation of the above-mentioned cleaning machine or the above-mentioned cleaning machine workstation.

[0042] Here, the cleaning machine workstation may include: a shell, which is combined with the dust barrel; a dust collecting motor, which is arranged inside the shell and generates an attraction force to suck the dust into the dust barrel; a capturing part, which is provided with a space inside to collect the dust sucked from the inside of the dust barrel by the dust collecting motor; a compression part, which can be rotatably arranged inside the capturing part to compress the collected dust; a compression motor, which is arranged outside the capturing part to generate power for the compression part to rotate; a power transmission part, which is arranged between the compression part and the compression motor, including a driving gear that rotates by the power of the compression motor; and a compression state sensing part, which is arranged adjacent to the driving gear and senses the rotation direction of the compression part and the rotation angle related to the rotation direction.

[0043] The display device may display the notification in a plurality of preset levels according to the dust collection amount calculated by the rotation angle sensed by the compression state sensing unit.

[0044] In addition, the display device may be a portable terminal.

[0045] The compression motor is constituted by a motor capable of bidirectional rotation in forward and reverse directions.

[0046] At this time, the cleaning machine workstation may further include a control unit, which calculates the dust collection amount.

[0047] The control unit calculates the dust collection amount using an average value of a rotation angle of the compression unit in the forward rotation and a rotation angle of the compression unit in the reverse rotation, with the forward rotation and the reverse rotation of the compression motor being one cycle.

[0048] In one embodiment of the present invention, when the calculated dust collection amount is equivalent to the last gear among the plurality of preset gears, the cleaning machine workstation is prohibited from driving the dust collection motor.

[0049] Effects of the Invention

[0050] According to the present invention, the compression part compresses the dust while moving in the inner space of the capturing part, thereby having an effect of improving the storage efficiency of the dust captured in the capturing part.

[0051] Furthermore, according to the present invention, the amount of dust captured in the capturing portion is displayed on the display portion, so there is an advantage that the user can easily check the amount of dust captured in the capturing portion without taking out the capturing portion for checking.

[0052] In addition, according to the present invention, the collected amount of dust compressed and stored inside the capture part is displayed on the display part in the form of a warning notification through multiple levels, thereby having the following advantage: the user can choose the appropriate time he or she wants to remove the dust before the capture part is full of dust.

[0053] In addition, according to the present invention, the amount of dust collected in the capturing portion is calculated by the rotation angle of the compression portion, and the above rotation angle is calculated based on the number of changes in the pattern formed on the driving gear. Therefore, it has the following advantages: even if the rotation speed of the compression portion changes due to the inclusion of foreign matter, the amount of dust can be accurately calculated.

[0054] The effects of the present invention are not limited to the effects mentioned above, and those skilled in the art can clearly understand other effects not mentioned here based on the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0079] The present invention can be implemented in various changes and can have various embodiments, so specific embodiments are illustrated and specifically described in the detailed description. This is not intended to limit the present invention to specific implementations, and the present invention includes all changes, equivalents and even substitutes that belong to the concept and technical scope of the present invention.

[0080] Figure 1 FIG. 2 is a diagram for explaining a cleaning machine in a cleaning machine system according to an embodiment of the present invention. Figure 2 From another perspective Figure 1 Figure of a cleaning machine, Figure 3 1 is a diagram for explaining the bottom of a dust barrel of a cleaning machine in a cleaning machine system of an embodiment of the present invention. Figure 4 This is a diagram for explaining a cleaning machine system according to an embodiment of the present invention.

[0081] Reference Figures 1 to 4 The cleaning machine system 3 of the embodiment of the present invention may include a cleaning machine 200 and a cleaning machine workstation 300 .

[0082] The cleaning machine system 3 may include a cleaning machine workstation 300. The cleaning machine 200 may be coupled to the cleaning machine workstation 300. The cleaning machine 200 may be coupled to a side surface of the cleaning machine workstation 300. The cleaning machine workstation 300 may remove dust from the dust cylinder 220 of the cleaning machine 200.

[0083] First, refer to Figures 1 to 3 , the structure of the cleaning machine 200 is described as follows.

[0084] The cleaning machine 200 is a cleaning machine that is manually operated by a user, for example, a handheld cleaning machine or a pole-type cleaning machine.

[0085] The cleaning machine 200 may be stored in the cleaning machine workstation 300. The cleaning machine 200 is supported by the cleaning machine workstation 300. The cleaning machine 200 may be coupled to the cleaning machine workstation 300.

[0086] In addition, in the embodiment of the present invention, the direction of the cleaning machine 200 is defined based on the bottom surface (lower side surface) of the dust canister 220 and the battery case 230 placed on the ground.

[0087] At this time, the front refers to the direction in which the suction unit 212 is arranged with the suction motor 214 as a reference, and the rear refers to the direction in which the handle 216 is arranged with the suction motor 214 as a reference. Moreover, the direction on the right is referred to as the right side, and the direction on the left is referred to as the left side, based on the suction unit 212 viewed from the suction motor 214. In addition, in the embodiment of the present invention, the upper side and the lower side are defined along the direction perpendicular to the ground, based on the bottom surface (lower side) of the dust can 220 and the battery housing 230 placed on the ground.

[0088] 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 air discharge cover 215, a handle 216, and an operation part 218.

[0089] The main body housing 211 may constitute the appearance of the cleaning machine 200. The main body housing 211 may provide a space for accommodating the suction motor 214 and a filter (not shown) therein. The main body housing 211 may be configured in a shape similar to a cylinder.

[0090] 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 combined with the extension pipe 250. The suction part 212 provides a flow path (hereinafter referred to as 'suction flow path') through which air including dust may flow.

[0091] The dust separation part 213 may be communicated 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 be communicated with the space inside the dust cylinder 220.

[0092] For example, the dust separation unit 213 may include at least one cyclone separation unit that separates dust by cyclone separation flow. In addition, the space inside the dust separation unit 213 may be connected to the above-mentioned suction flow path. Therefore, the air and dust sucked in through the suction unit 212 flow in a spiral along the inner circumferential surface of the dust separation unit 213. Therefore, a cyclone separation flow is generated in the internal space of the dust separation unit 213.

[0093] The dust separator 213 is connected to the suction unit 212 and applies the principle of a dust collector using centrifugal force to separate dust sucked into the body 210 through the suction unit 212 .

[0094] The dust separator 213 may further include a secondary cyclone separator for separating dust again from the air discharged from the cyclone separator. At this time, the secondary cyclone separator is located inside the cyclone separator so that the size of the dust separator is minimized. The secondary cyclone separator may include a plurality of cyclone separator bodies arranged in parallel. The air discharged from the cyclone separator is divided into a plurality of cyclone separator bodies and passes through.

[0095] At this time, the axis of the cyclone separation flow of the secondary cyclone separation section can also extend in the up and down directions, and the axis of the cyclone separation flow of the cyclone separation section and the axis of the cyclone separation flow of the secondary cyclone separation section can form a coaxial axis in the up and down directions, which can be collectively referred to as the axis of the cyclone separation flow of the dust separation section 213.

[0096] The suction motor 214 may generate a suction force for sucking 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.

[0097] The air outlet 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 air outlet cover 215. As an example, a high efficiency (HEPA) filter may be housed in the air outlet cover 215.

[0098] The air discharge cover 215 is formed with an air discharge port for discharging the air sucked in by the suction force of the suction motor 214 .

[0099] A flow guide is disposed on the air discharge cover 215. The flow guide can guide the flow of air discharged through the air discharge port.

[0100] The handle 216 is held by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed into a shape similar to a cylinder. Alternatively, the handle 216 can be formed into a curved cylinder. The handle 216 can be arranged to form a predetermined angle with the main housing 211, the suction motor 214, or the dust separation unit 213.

[0101] The handle 216 may include: a holding portion 216a, which is formed in a columnar shape so that the user can grasp it; a first extension portion 216b, which is connected to one side end portion of the holding portion 216a in the length direction (axial direction) and extends toward the suction motor 214; and a second extension portion 216c, which is connected to the other side end portion of the holding portion 216a in the length direction (axial direction) and extends toward the dust canister 220.

[0102] The upper surface of the handle 216 may form a part of the appearance of the upper surface of the cleaning machine 200. Thus, when the user holds the handle 216, a part of the structure of the cleaning machine 200 is prevented from contacting the user's arm.

[0103] The first extension portion 216b may extend from the grip portion 216a toward the main body housing 211 or the suction motor 214. At least a portion of the first extension portion 216b may extend in a horizontal direction.

[0104] The second extension portion 216c may extend from the grip portion toward the dust tube 220. At least a portion of the second extension portion 216c may extend in a horizontal direction.

[0105] The operation part 218 may be disposed on the handle 216. The operation part 218 may be disposed on an inclined surface formed in an upper region of the handle 216. The user may input an operation or stop command of the cleaning machine 200 through the operation part 218.

[0106] Information related to the operation of the cleaning machine 200 (eg, suction intensity, remaining charge level of the battery, etc.) can be visually displayed on the operation unit 218. That is, the operation unit 218 can be used as a display device.

[0107] The cleaning machine 200 may include a dust canister 220. The dust canister 220 may communicate with the dust separation portion 213. The dust canister 220 may store dust separated from the dust separation portion 213.

[0108] The dust canister 220 may include a dust canister body 221 , a discharge cover 222 , a dust canister compression rod 223 , and a compressor (not shown).

[0109] The dust container body 221 may provide a space capable of storing dust separated from the dust separation unit 213. As an example, the dust container body 221 may be formed in a shape similar to a cylinder.

[0110] A part of the lower side (bottom) of the dust tube body 221 is open. In addition, a lower surface extension portion 221a is formed on the lower side (bottom) of the dust tube body 221. The lower surface extension portion 221a is formed in a manner of blocking a part of the lower side of the dust tube body 221.

[0111] The dust barrel 220 may include a discharge cover 222. The discharge cover 222 may be disposed on a lower side of the dust barrel 220.

[0112] The discharge cover 222 is formed in a manner of opening and closing one end portion in the length direction of the dust tube body 221. Specifically, the discharge cover 222 can selectively open and close the lower portion of the dust tube 220 opened downward.

[0113] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a is formed in a manner to block a portion of the lower side of the dust barrel body 221. The cover body 222a can rotate downward with the hinge portion 222b as a reference. The hinge portion 222b can be arranged adjacent to the battery housing 230. The hinge portion 222b can have a torsion spring 222d. Therefore, when the discharge cover 222 is separated from the dust barrel body 221, the cover body 222a is supported by the elastic force of the torsion spring 222d to be in a state of rotating more than a specified angle with the hinge portion 222b as an axis in the dust barrel body 221.

[0114] The discharge cover 222 can be combined with the dust canister 220 by hook coupling. In addition, the discharge cover 222 can be separated from the dust canister 220 by a coupling rod 222c. The coupling rod 222c can be arranged in front of the dust canister. Specifically, the coupling rod 222c can be arranged on the outer side surface of the front side of the dust canister 220. When an external force is applied, the coupling rod 222c elastically deforms the hook extending from the cover body 222a to release the hook coupling between the cover body 222a and the dust canister body 221.

[0115] When the discharge cover 222 is closed, the lower side surface of the dust tube 220 is blocked (sealed) by the discharge cover 222 and the extending portion 221 a of the lower surface.

[0116] The dust cartridge 220 may include a dust cartridge compression rod 223 (see Figure 2 ). The dust barrel compression rod 223 can be arranged outside the dust barrel 220 or the dust separation part 213. The dust barrel compression rod 223 is arranged outside the dust barrel 220 or the dust separation part 213 in a manner that it can move up and down. The dust barrel compression rod 223 can be connected to a compressor (not shown). In the case where the dust barrel compression rod 223 is moved downward by an external force, the compressor (not shown) also moves downward together. Thereby, user convenience can be provided. The compressor (not shown) and the dust barrel compression rod 223 can return to the original position by an elastic component (not shown). Specifically, when the external force applied to the dust barrel compression rod 223 is released, the elastic component can move above the dust barrel compression rod 223 and the compressor (not shown).

[0117] The compressor (not shown) can be arranged inside the dust barrel body 221. The compressor can move in the internal space of the dust barrel body 221. Specifically, the compressor can move up and down inside the dust barrel body 221. Thus, the compressor can compress the dust inside the dust barrel body 221 downward. In addition, when the discharge cover 222 is separated from the dust barrel body 221 and the lower part of the dust barrel 220 is opened, the compressor moves from the upper part to the lower part of the dust barrel 220 to remove foreign matter such as residual dust inside the dust barrel 220. Thus, no residual dust remains inside the dust barrel 220, thereby improving the attractiveness of the cleaning machine. At the same time, no residual dust remains inside the dust barrel 220, thereby removing the odor caused by the residual matter.

[0118] The cleaning machine 200 may include a battery housing 230. The battery housing 230 may contain a battery 240. The battery housing 230 may be disposed on the lower side of the handle 216. As an example, the battery housing 230 may be in a hexahedral shape with an open lower portion. The back of the battery housing 230 may be connected to the handle 216.

[0119] The battery case 230 may include a storage portion that is open downward. The battery 240 can be attached and detached through the storage portion of the battery case 230 .

[0120] Cleaning machine 200 may include a battery 240 .

[0121] For example, the battery 240 may be detachably coupled to the cleaning machine 200. The battery 240 may be detachably coupled to the battery housing 230. As an example, the battery 240 may be inserted into the battery housing 230 from below. With such a structure, the portability of the cleaning machine 200 may be improved.

[0122] At the same time, the battery 240 may be integrally disposed inside the battery housing 230. At this time, the lower surface of the battery 240 is not exposed to the outside.

[0123] The battery 240 can supply power to the suction motor 214 of the cleaning machine 200. The battery 240 can be disposed at the lower portion of the handle 216. The battery 240 can be disposed at the rear of the dust barrel 220.

[0124] According to an embodiment, when the battery 240 is coupled to the battery housing 230, the lower surface of the battery 240 may be exposed to the outside. When the cleaning machine 200 is placed at the bottom, the battery 240 may be placed at the bottom, so that the battery 240 may be directly separated from the battery housing 230. In addition, the lower surface of the battery 240 is exposed to the outside and directly contacts the external air of the battery 240, so the cooling performance of the battery 240 may be improved.

[0125] In addition, when the battery 240 is integrally fixed to the battery case 230, the structure for detaching the battery 240 and the battery case 230 can be omitted, so the overall size of the cleaning machine 200 can be reduced and the weight can be reduced.

[0126] The cleaning machine 200 may include an extension pipe 250. The extension pipe 250 may communicate with the cleaning module 260. The extension pipe 250 may communicate with the body 210. The extension pipe 250 may communicate with the suction part 212 of the body 210. The extension pipe 250 may be formed in a long cylindrical shape.

[0127] The main body 210 may be connected to the extension tube 250. The main body 210 may be connected to the cleaning module 260 through the extension tube 250. The main body 210 generates suction force through the suction motor 214, and provides suction force to the cleaning module 260 through the extension tube 250. Through the cleaning module 260 and the extension tube 250, external dust flows into the main body 210.

[0128] The cleaning machine 200 may include a cleaning module 260. The cleaning module 260 may communicate with the extension pipe 250. Therefore, external air flows into the main body 210 of the cleaning machine 200 through the cleaning module 260 and the extension pipe 250 by a suction force generated in the main body 210 of the cleaning machine 200.

[0129] The dust in the dust barrel 220 of the cleaning machine 200 is captured by gravity to the capture part 370 of the cleaning machine workstation 300. At the same time, the dust in the dust barrel 220 is captured by the attraction force of the dust collecting motor 391 disposed inside the cleaning machine workstation 300 to the capture part 370 of the cleaning machine workstation 300. Thus, the dust in the dust barrel of the cleaning machine can be removed without the need for additional operations by the user, thus providing convenience for the user. In addition, the trouble of the user having to empty the dust barrel every time can be eliminated. In addition, when the dust barrel is emptied, dust can be prevented from scattering.

[0130] The cleaning machine 200 can be coupled to the side surface of the housing 310. Specifically, the main body 210 of the cleaning machine 200 can be stored in the coupling portion 320. More specifically, the dust barrel 220 and the battery housing 230 of the cleaning machine 200 can be coupled to the coupling surface 321 of the coupling portion 320. The outer peripheral surface of the dust barrel main body 221 can be coupled to the dust barrel guide surface 322. The suction portion 212 can be coupled to the suction portion guide surface 326 of the coupling portion 320. With such a structure, the central axis of the dust barrel 220 is arranged in a direction parallel to the ground, and the extension tube 250 can be arranged in a direction perpendicular to the ground.

[0131] Next, the structure of the cleaning machine workstation 300 according to the embodiment of the present invention is described.

[0132] Reference Figure 4, the cleaning machine 200 may be coupled to the cleaning machine workstation 300. Specifically, the main body of the cleaning machine 200 may be coupled to the side surface of the cleaning machine workstation 300. More specifically, the dust barrel 220 of the cleaning machine 200 is coupled to the side surface of the cleaning machine workstation 300 and is coupled through a side configured with a discharge cover 222. Thus, when the discharge cover 222 is opened, the dust of the dust barrel 220 is captured inside the cleaning machine workstation 300 and removed.

[0133] The cleaning machine workstation 300 may include a housing 310. The housing 310 may form the appearance of the cleaning machine workstation 300. Specifically, the housing 310 may be formed in a columnar shape including at least one outer wall surface. As an example, the housing 310 may be formed in a shape similar to a quadrangular column.

[0134] The housing 310 may form a space inside which the capturing portion 370 and the dust suction module 390 are stored.

[0135] The housing 310 may include a bottom surface 311 , an outer wall surface 312 , and an upper surface 313 .

[0136] The bottom surface 311 may support the lower side of the dust suction module 390 in the gravity direction. That is, the bottom surface 311 may support the lower side of the dust collecting motor 391 of the dust suction module 390.

[0137] At this time, the bottom surface 311 can be arranged toward the ground. The bottom surface 311 can be arranged parallel to the ground or inclined at a predetermined angle to the ground. Such a structure has the following advantages: the dust collecting motor 391 can be stably supported, and when combined with the cleaning machine 200, the entire weight can be balanced.

[0138] In addition, according to an embodiment, the bottom surface 311 may further include: a ground support portion 311a, which prevents the cleaning machine workstation 300 from falling and increases the area of ​​contact with the ground in order to maintain balance. As an example, the ground support portion 311a may be a plate extending from the bottom surface 311, and one or more frames protrude and extend along the ground direction and are formed on the bottom surface 311.

[0139] The outer wall surface 312 may be a surface formed along the gravity direction, or may be a surface connected to the bottom surface 311. For example, the outer wall surface 312 may be a surface vertically connected to the bottom surface 311. As a different embodiment, the outer wall surface 312 may be arranged to be inclined at a predetermined angle to the bottom surface 311.

[0140] The outer wall surface 312 may include at least one surface. For example, the outer wall surface 312 may include a first outer wall surface 312a, a second outer wall surface 312b, a third outer wall surface 312c, and a fourth outer wall surface 312d.

[0141] At this time, in this embodiment, the first outer wall surface 312a can be configured at the front of the cleaning machine workstation 300. Here, the front refers to the surface of the cleaning machine 200 exposed when the cleaning machine 200 is combined with the cleaning machine workstation 300. Therefore, the first outer wall surface 312a can form the appearance of the front of the cleaning machine workstation 300.

[0142] In addition, in order to understand the present embodiment, directions are defined as follows: In the present embodiment, directions are defined in a state where the cleaning machine 200 is coupled to the cleaning machine workstation 300 .

[0143] A direction in which the cleaning machine 200 is exposed to the outside of the cleaning machine station 300 when the cleaning machine 200 is coupled to the cleaning machine station 300 is referred to as a front.

[0144] From another point of view, when the cleaning machine 200 is coupled to the cleaning machine station 300, the direction in which the suction motor 214 of the cleaning machine 200 is arranged is called the front, and the opposite direction of the direction in which the suction motor 214 is arranged in the cleaning machine station 300 is called the rear.

[0145] Furthermore, a surface opposite to the front surface with respect to the internal space of the housing 310 may be referred to as the back surface of the cleaning machine workstation 300. Therefore, the back surface may refer to a direction in which the second outer wall surface 312b is formed.

[0146] Furthermore, when observing the front surface based on the internal space of the housing 310, the left side is referred to as the left side, and the right side is referred to as the right side. Therefore, the left side may indicate the direction in which the third outer wall surface 312c is formed, and the right side may indicate the direction in which the fourth outer wall surface 312d is formed.

[0147] The first outer wall surface 312a may be formed not only in a flat surface but also in a curved surface as a whole or partially including a curved surface.

[0148] The first outer wall surface 312a may be provided with a coupling portion 320. With such a structure, the cleaning machine 200 may be coupled to the cleaning machine workstation 300 and supported by the cleaning machine workstation 300. The specific structure of the coupling portion 320 will be described later.

[0149] In addition, a structure for storing cleaning modules 260 of various forms used in the cleaning machine 200 may be additionally provided on the first outer wall surface 312 a .

[0150] In this embodiment, the second outer wall surface 312b may be a surface opposite to the first outer wall surface 312a. That is, the second outer wall surface 312b may be disposed at the back of the cleaning machine workstation 300. The second outer wall surface 312b may form the appearance of the back of the cleaning machine workstation 300.

[0151] In this embodiment, the third outer wall surface 312c and the fourth outer wall surface 312d may represent surfaces connecting the first outer wall surface 312a and the second outer wall surface 312b. In this case, the third outer wall surface 312c may be arranged on the left side of the cleaning machine workstation 300, and the fourth outer wall surface 312d may be arranged on the right side of the cleaning machine workstation 300. Alternatively, the third outer wall surface 312c may also be arranged on the right side of the cleaning machine workstation 300, and the fourth outer wall surface 312d may also be arranged on the left side of the cleaning machine workstation 300.

[0152] The third outer wall surface 312c or the fourth outer wall surface 312d may be formed in a flat shape, may be formed in a curved shape as a whole, or may be formed to include a curved surface in part.

[0153] In addition, a structure for storing various types of cleaning modules 290 used in the cleaning machine 200 may be additionally provided on the third outer wall surface 312 c or the fourth outer wall surface 312 d .

[0154] The upper surface 313 may form the upper appearance of the cleaning machine workstation. That is, the upper surface 313 may indicate the uppermost surface of the cleaning machine workstation in the gravity direction and exposed to the outside.

[0155] For reference, in the present embodiment, the upper side and the lower side respectively refer to the upper side and the lower side formed along the gravity direction (the direction perpendicular to the ground) when the cleaning machine workstation 300 is set on the ground.

[0156] At this time, the upper surface 313 may be arranged not only in parallel with the ground but also inclined at a predetermined angle with respect to the ground.

[0157] A display unit 530 may be disposed on the upper surface 313. For example, the display unit 530 may display the status of the cleaning machine station 300 and the status of the cleaning machine 200, and may also display information such as a map related to the cleaning progress and the cleaning area.

[0158] In addition, according to an embodiment, the upper surface 313 may be provided separately from the outer wall surface 312. At this time, when the upper surface 313 is separated, the battery separated from the cleaning machine 200 may be accommodated in the inner space surrounded by the outer wall surface 312, and a terminal (not shown) for charging the separated battery may be provided.

[0159] Figure 5 It is a diagram for explaining the joint in the cleaning machine workstation according to the embodiment of the present invention.

[0160] Reference Figure 5The cleaning machine workstation 300 may include a coupling portion 320 for coupling to the cleaning machine 200. Specifically, the coupling portion 320 may be configured on the first outer wall surface 312a and coupled with the dust barrel 220 of the cleaning machine 200. The dust barrel 220 and the main body 210 and battery housing 230 of the cleaning machine 200 may be coupled to the coupling portion 320.

[0161] The coupling portion 320 may include a coupling surface 321. The coupling surface 321 may be disposed on a side surface of the housing 310. As an example, the coupling surface 321 may be a groove-shaped surface that is recessed from the first outer wall surface 312a toward the inner side of the cleaning machine workstation 300. That is, the coupling surface 321 may be a surface formed by forming a step difference with the first outer wall surface 312a.

[0162] The cleaning machine 200 may be coupled to the coupling surface 321. As an example, the coupling surface 321 may contact the lower side of the dust barrel 220 and the battery housing 230 of the cleaning machine 200. Here, the lower side may refer to the side facing the ground when the user uses the cleaning machine 200 or places the cleaning machine 200 on the ground.

[0163] As an example, the angle formed by the coupling surface 321 and the ground can be a right angle. Thus, when the cleaning machine 200 is coupled to the coupling surface 321, the space of the cleaning machine workstation 300 can be minimized.

[0164] As another example, the connection surface 321 may be arranged to be inclined at a predetermined angle to the ground. Thus, when the cleaning machine 200 is connected to the connection surface 321, the cleaning machine station 300 can be stably supported.

[0165] The coupling surface 321 may be formed with a dust tube and a hole 321a so that air from the outside of the housing 310 flows into the inside. The dust tube and the hole 321a are formed in a hole shape corresponding to the shape of the dust tube 220 so that dust in the dust tube 220 flows into the capture portion 370. The dust tube and the hole 321a are formed corresponding to the shape of the discharge cover 222 of the dust tube 220. The dust tube and the hole 321a may be formed in communication with the flow path portion 380 described later (see FIG. 1 ). Figure 8 ).

[0166] The coupling portion 320 may include a dust tube guide surface 322 . The dust tube guide surface 322 may be disposed on the first outer wall surface 312 a . The dust tube guide surface 322 may be connected to the first outer wall surface 312 a . In addition, the dust tube guide surface 322 may be connected to the coupling surface 321 .

[0167] The dust tube guide surface 322 may be formed in a shape corresponding to the outer side surface of the dust tube 220. The front outer side surface of the dust tube 220 may be coupled to the dust tube guide surface 322. Thus, the convenience of coupling the cleaning machine 200 to the coupling surface 321 may be provided.

[0168] In addition, a protrusion moving hole 322a may be formed on the dust tube guide surface 322, and the push protrusion 351 described later may move linearly along the protrusion moving hole 322a (see Fig.11 ). In addition, a gear box 355 for accommodating gears and the like of the cover opening unit 350 described later may be provided on the lower side of the dust barrel guide surface 322 in the gravity direction. At this time, a guide space 322b for pushing the protrusion 351 to move may be formed between the dust barrel guide surface 322 and the lower side surface and the upper surface of the gear box 355. In addition, the guide space 322b may be connected to the first flow path 381 through the bypass hole 322c. That is, the protrusion moving hole 322a, the guide space 322b, the bypass hole 322c and the first flow path 381 may form a flow path. With such a structure, there is the following advantage: when the dust collecting motor 391 is operated in a state where the dust barrel 220 is coupled to the coupling portion 320, dust and the like remaining in the dust barrel 220 and the dust barrel guide surface 322 may be sucked in through the flow path.

[0169] The coupling portion 320 may include a guide protrusion 323. The guide protrusion 323 may be disposed on the coupling surface 321. The guide protrusion 323 may protrude upward on the coupling surface 321. Two guide protrusions 323 may be disposed spaced apart from each other. The distance between the two spaced apart guide protrusions 323 corresponds to the width of the battery housing 230 of the cleaning machine 200. Thus, the convenience of coupling the cleaning machine 200 to the coupling surface 321 can be provided.

[0170] The joint part 320 may include a joint part side wall 324. The joint part side wall 324 may represent a wall surface disposed on two side surfaces of the joint surface 321, and may be vertically connected to the joint surface 321. The joint part side wall 324 may be connected to the first outer wall surface 312a. In addition, the joint part side wall 324 may form a surface connected to the dust barrel guide surface 322. Thus, the cleaning machine 200 can be stably stored.

[0171] The coupling part 320 may include a coupling sensor. The coupling sensor may sense whether the cleaning machine 200 is coupled to the coupling part 320.

[0172] The combination sensor may include a contact sensor. As an example, the combination sensor may include a microswitch. In this case, the combination sensor may be configured on the guide protrusion 323. Therefore, when the battery housing 230 or the battery 240 of the cleaning machine 200 is connected between a pair of guide protrusions 323, the combination sensor is contacted, and the combination sensor can sense that the cleaning machine 200 has been connected.

[0173] In addition, the combined sensor may also include a non-contact sensor. As an example, the combined sensor may include an infrared sensor (IR sensor). In this case, the combined sensor may be configured on the combined portion side wall 324. Therefore, when the dust canister 220 or the main body 210 of the cleaning machine 200 passes through the combined portion side wall 324 and reaches the combined surface 321, the combined sensor may sense the presence or absence of the dust canister 220 or the main body 210.

[0174] In a state where the cleaning machine 200 is coupled to the cleaning machine workstation 300 , the coupling sensor may be opposite to the dust cylinder 220 or the battery housing 230 of the cleaning machine 200 .

[0175] The coupling sensor may be a unit that determines whether power is applied to the battery 240 of the cleaning machine 200 and whether the cleaning machine 200 is coupled.

[0176] The coupling portion 320 may include a suction portion guide surface 326. The suction portion guide surface 326 may be disposed on the first outer wall surface 312a. The suction portion guide surface 326 may be connected to the dust tube guide surface 322. The suction portion 212 may be coupled to the suction portion guide surface 326. The shape of the suction portion guide surface 326 may be formed in a shape corresponding to the shape of the suction portion 212.

[0177] The coupling portion 320 may further include a fixing member access hole 327. The fixing member access hole 327 is formed in a long hole shape along the coupling portion side wall 324 so that the fixing member 331 can be accessed.

[0178] With such a structure, when the user connects the cleaning machine 200 to the connecting portion 320 of the cleaning machine workstation 300, the main body 210 of the cleaning machine 200 is stably arranged on the connecting portion 320 through the dust barrel guide surface 322, the guide protrusion 323 and the suction portion guide surface 326. Thus, the convenience of connecting the dust barrel 220 and the battery housing 230 of the cleaning machine 200 to the connecting surface 321 can be provided.

[0179] In addition, the cleaning machine workstation 300 may further include a charging terminal 328. The charging terminal 328 may be disposed at the coupling portion 320. The charging terminal 328 may be electrically connected to the cleaning machine 200 coupled to the coupling portion 320. The charging terminal 328 may supply power to a battery of the cleaning machine 200 coupled to the coupling portion 320.

[0180] In addition, the cleaning machine workstation 300 may further include a side surface door. The side surface door may be configured on the housing 310. The side surface door may selectively expose the capture portion 370 to the outside. Thus, the user may easily remove the capture portion 370 from the cleaning machine workstation 300.

[0181] Figure 6It is a diagram for explaining a fixing unit in a cleaning machine workstation according to an embodiment of the present invention.

[0182] Reference Figure 6 , the cleaning machine workstation 300 of the present invention may include a fixing unit 330. The fixing unit 330 may be disposed on the side wall 324 of the coupling portion. In addition, the fixing unit 330 may be disposed on the back of the coupling surface 321. The fixing unit 330 may fix the cleaning machine 200 coupled to the coupling surface 321. Specifically, the fixing unit 330 may fix the dust barrel 220 and the battery housing 230 of the cleaning machine 200 coupled to the coupling surface 321.

[0183] The fixing unit 330 may include a fixing part 331 that fixes the dust barrel 220 and the battery housing 230 of the cleaning machine 200, and a fixing part motor 580 that drives the fixing part 331. In addition, the fixing unit 330 may further include a fixing part chain 335 that transmits the power of the fixing part motor 580 to the fixing part 331.

[0184] The fixing member 331 may be disposed on the joint sidewall 324 and may reciprocate on the joint sidewall 324 to fix the dust cylinder 220. Specifically, the fixing member 331 may be received inside the fixing member access hole 327.

[0185] The fixing members 331 may be disposed on both sides of the coupling portion 320. As an example, two fixing members 331 may be disposed symmetrically and in pairs with the coupling surface 321 as the center.

[0186] The fixing part motor 580 may provide power to move the fixing member 331 .

[0187] The fixing part chain 335 can convert the rotational force of the fixing part motor 580 into the reciprocating movement of the fixing member 331 .

[0188] When the cleaning machine 200 is combined, the fixed seal 336 can be arranged on the dust tube guide surface 322 to achieve airtightness of the dust tube 220. With such a structure, when the dust tube 220 of the cleaning machine 200 is combined, the fixed seal 336 is pressed by the dead weight of the cleaning machine 200, thereby sealing the dust tube 220 and the dust tube guide surface 322.

[0189] The fixed seal 336 may be disposed on a virtual extension line of the fixed member 331. With such a structure, when the fixed part motor 580 is operated to cause the fixed member 331 to press the dust canister 220, the surroundings of the dust canister 220 at the same height can be sealed.

[0190] According to the embodiment, the fixed seal 336 is arranged on the dust tube guide surface 322 in a zigzag shape corresponding to the arrangement of the cover opening unit 350 described later.

[0191] Therefore, when the coupling part 320 is configured with the main body 210 of the cleaning machine 200, the fixing unit 330 can fix the main body 210 of the cleaning machine 200. Specifically, when the coupling sensor 325 senses that the main body 210 of the cleaning machine 200 is coupled to the coupling part 320 of the cleaning machine workstation 300, the fixing part motor 580 can move the fixing member 331 to fix the main body 210 of the cleaning machine 200.

[0192] Thus, residual dust is prevented from remaining in the dust barrel, and the attractiveness of the cleaning machine can be improved. Simultaneously, residual dust is prevented from remaining in the dust barrel, and the odor generated by the residual can be removed.

[0193] Figure 7 and Figure 8 As a diagram for explaining the relationship between a cleaning machine and a door unit in a cleaning machine station according to an embodiment of the present invention, Figure 7 2 is a diagram showing a state in which the door locks the dust cylinder and the hole. Figure 8 1 is a diagram showing a state in which the door opens the dust tube and the hole.

[0194] Reference Figure 7 and Figure 8 The cleaning machine workstation 300 of the present invention may include a door unit 340. The door unit 340 is configured to open and close the dust cylinder and the hole 321a.

[0195] The door unit 340 may include a door 341 , a door motor 342 , and a door arm 343 .

[0196] The door 341 is hingedly coupled to the coupling surface 321, and can open and close the dust tube and the hole 321a. The door 341 may include a door body 341a.

[0197] The door body 341a may be formed in a shape that blocks the dust tube and the hole 321a. As an example, the door body 341a may be formed in a disk-like shape.

[0198] Based on the state in which the door body 341a blocks the dust tube and the hole 321a, a hinge portion is arranged on the upper side of the door body 341a, and an arm coupling portion 341b is arranged on the lower side of the door body 341a.

[0199] The door body 341a may be formed into a shape that seals the dust canister and the hole 321a. For example, the outer side surface of the door body 341a exposed to the outside of the cleaning machine workstation 300 is formed to have a diameter corresponding to the diameter of the dust canister and the hole 321a, and the inner side surface disposed inside the cleaning machine workstation 300 is formed to have a diameter larger than the diameter of the dust canister and the hole 321a. In addition, a step is generated between the outer side surface and the inner side surface. In addition, the hinge portion and the arm joint 341b are connected on the inner side surface, and at least one or more reinforcing ribs for increasing the supporting force of the door body 341a are protrudingly formed.

[0200] The hinge part may be a unit that hinges the door 341 to the coupling surface 321. The hinge part may be disposed at an upper end portion of the door body 341a and may be coupled to the coupling surface 321.

[0201] The arm coupling part 341b may be a unit rotatably coupled to the door arm 343. The arm coupling part 341b may be disposed at a lower side of the door body 341a, and rotatably coupled to the door body 341a, and rotatably coupled to the door arm 343.

[0202] With such a structure, when the door 341 closes the dust canister and the hole 321a, when the door arm 343 pulls the door body 341a, the door body 341a rotates toward the inside of the cleaning machine workstation 300 with the hinge as the axis, and the dust canister and the hole 321a are opened. In addition, when the door arm 343 pushes the door body 341a, the door body 341a rotates toward the outside of the cleaning machine workstation 300 with the hinge 341b as the axis, so that the dust canister and the hole 321a can be blocked.

[0203] In addition, when the cleaning machine 200 is coupled to the cleaning machine workstation 300 and the discharge cover 222 is separated from the dust can body 210, the door 341 may contact the discharge cover 222. And, according to the rotation of the door 341, the discharge cover 222 may rotate in conjunction with the door 341.

[0204] The door motor 342 can provide power to rotate the door 341. Specifically, the door motor 342 can rotate the door arm 343 in a forward or reverse direction. Here, the forward direction refers to the direction in which the door arm 343 pulls the door 341. Therefore, when the door arm 343 rotates in the forward direction, the dust canister and the hole 321a are opened. In addition, the reverse direction refers to the direction in which the door arm 343 pushes the door 341. Therefore, when the door arm 343 rotates in the reverse direction, the dust canister and at least a portion of the hole 321a are locked. The forward direction is the opposite direction to the reverse direction.

[0205] The door arm 343 connects the door 341 and the door motor 342 , and opens and closes the door 341 using power generated by the door motor 342 .

[0206] As an example, the door arm 343 may include a first door arm 343a and a second door arm 343b. One end of the first door arm 343a may be combined with the door motor 342. The first door arm 343a may be rotated by the power of the door motor 342. The other end of the first door arm 343a may be rotatably combined with the second door arm 343b. The first door arm 343a may transmit the force transmitted from the door motor 342 to the second door arm 343b. One end of the second door arm 343b may be combined with the first door arm 343a. The other end of the second door arm 343b may be combined with the door 341. The second door arm 343b pushes or pulls the door 341 to open and close the dust cylinder and the hole 321a.

[0207] The door unit 340 is opened in the same manner as the discharge cover 222 of the cleaning machine 200 is opened. In addition, when the door unit 340 is closed, the discharge cover 222 of the cleaning machine 200 is closed in conjunction therewith.

[0208] When the dust in the dust barrel 220 of the cleaning machine 200 is removed, the door motor 342 rotates the door 341, so that the discharge cover 222 can be coupled to the dust barrel body 221. Specifically, the door motor 342 rotates the door 341, so that the door 341 rotates with the hinge part 341b as the reference, and the door 141 rotating with the hinge part 341b as the reference can push the discharge cover 222 toward the dust barrel body 221.

[0209] Fig. 9 This is a diagram for explaining the relationship between the cleaning machine and the lid opening unit in the cleaning machine station according to the embodiment of the present invention.

[0210] Reference Fig. 9 The cleaning machine workstation 300 of the present invention may include a cover opening unit 350. The cover opening unit 350 may be disposed at the coupling portion 320, and may open the discharge cover 222 of the cleaning machine 200.

[0211] The cover opening unit 350 may include a push protrusion 351 , a cover opening motor 352 , a cover opening gear 353 , and a gear box 355 .

[0212] When the cleaning machine 200 is coupled, the pushing protrusion 351 moves in a manner of pressing the coupling rod 222 c .

[0213] The push protrusion 351 may be disposed on the dust tube guide surface 322. Specifically, a protrusion moving hole may be formed on the dust tube guide surface 322, and the push protrusion 351 is exposed to the outside through the protrusion moving hole.

[0214] When the cleaning machine 200 is combined, the pushing protrusion 351 is arranged at a position to press the combining rod 222c. That is, the combining rod 222c is arranged on the protrusion moving hole. In addition, the combining rod 222c is arranged on the moving area of ​​the pushing protrusion 351.

[0215] The push protrusion 351 performs a linear reciprocating motion by pressing the coupling rod 222c. Specifically, the push protrusion 351 is coupled to the gear box 355 and guided to perform a linear movement. The push protrusion 351 is coupled to the cover opening gear 353, so that the push protrusion 351 moves together with the movement of the cover opening gear 353.

[0216] The cover opening motor 352 provides power to move the push protrusion 351. Specifically, the cover opening motor 352 can rotate the motor shaft in the forward or reverse direction. Here, the forward direction refers to the direction in which the push protrusion 351 presses the coupling rod 222c. In addition, the reverse direction refers to the direction in which the push protrusion 351 pressing the coupling rod 222c returns to the original position. The forward direction may be the opposite direction to the reverse direction.

[0217] The cover opening gear 353 may be combined with the cover opening motor 352, and use the power of the cover opening motor 352 to move the push protrusion 351. Specifically, the cover opening gear 353 may be accommodated in the gear box 355. The driving gear 353a of the cover opening gear 353 may be combined with the motor shaft of the cover opening motor 352 to receive power. The driven gear 353b of the cover opening gear 353 may be combined with the push protrusion 351 to move the push protrusion 351. As an example, the driven gear 353b may be provided in a rack shape to mesh with the driving gear 353a, and receive power from the driving gear 353a.

[0218] At this time, the discharge cover 222 may be provided with a torsion spring 222d. The discharge cover 222 can be rotated more than a predetermined angle by the elastic force of the torsion spring 222d and supported at the rotated position. Therefore, the discharge cover 222 can be opened, and the dust barrel and the hole 321a are connected to the inside of the dust barrel 220.

[0219] The gear box 355 is disposed inside the housing 310 and is arranged at the lower side of the coupling portion 320 in the gravity direction, and the cover opening gear 353 can be accommodated inside.

[0220] According to the present invention, the cover opening unit 350 allows the user to open the dust cylinder 220 without separately opening the discharge cover 222 of the cleaning machine, thereby improving convenience.

[0221] In addition, the discharge cover 222 is opened in a state where the cleaning machine 200 is coupled to the cleaning machine station 300, thereby having an effect of preventing dust from being scattered.

[0222] Fig.10 This is a diagram for explaining the arrangement of components of the cleaning machine station 300 according to the embodiment of the present invention.

[0223] Reference Fig.10The cover opening unit 350 described above may be disposed at the lower side of the coupling portion 320 , and the flow path portion 380 is disposed at the rear side of the coupling portion 320 and the cover opening unit 350 .

[0224] Hereinafter, the flow path connected from the coupling portion 320 to the capturing portion 370 is referred to as a first flow path 381. The capturing portion 370 for collecting dust is connected to the lower end of the first flow path 381 and is arranged.

[0225] The cleaning machine workstation 300 may further include a cavity 360 having a space for storing the capture portion 370. In this case, the capture portion 370 may be detachably provided in the cavity 360. The cavity 360 may be a component detachably provided in the housing 310, or may represent a storage space for the capture portion 370 formed integrally with the housing 310.

[0226] A sterilization unit 450 may be disposed on an upper side of the cavity 360 .

[0227] The sterilizing unit 450 sterilizes the dust captured by the capturing unit 370. The sterilizing unit 450 may include a light source that emits sterilizing light and a light source protection panel disposed below the light source.

[0228] In an optional embodiment, the light source and the protective panel can be combined with the cavity 360 in the form of being accommodated in a separately provided sterilization unit housing. Or in an optional embodiment, the light source and the protective panel can be combined with the cavity 360 in the form of being accommodated in a space formed by bending a portion of the upper surface of the cavity 360.

[0229] Regarding the combination form of the sterilization part 450 and the chamber 360, as long as the light source of the sterilization part 450 is arranged in a manner to emit sterilization light to the capture part 370, the arrangement form is not limited to any one embodiment.

[0230] Here, the light source may include at least one light emitting diode (LED) that emits sterilizing light having a sterilizing power capable of removing bacteria. The sterilizing light emitted by the light source may have different wavelengths depending on the type of the light emitting diode.

[0231] As an example, the light source may be a light emitting diode that emits ultraviolet light having a wavelength range of UV-C. Ultraviolet light is divided into UV-A (315nm to 400nm), UV-B (280nm to 315nm), and UV-C (200nm to 280nm) according to the wavelength, and ultraviolet light in the UV-C region damages the double helix of DNA of microorganisms and inhibits the reproduction of microorganisms.

[0232] Alternatively, as another example, the light source may be a light emitting diode that emits visible light having a wavelength of 405 nm. Blue light having a wavelength of 405 nm has a wavelength in the boundary region between visible light and ultraviolet light and has been shown to have a bactericidal effect.

[0233] The protective panel is arranged at a predetermined distance from the light source to prevent the light source from being damaged. In this case, the protective panel may be made of a material that allows the light source to have a maximum transmittance. As an example, the protective panel may be made of quartz. As is known to all, quartz does not hinder the transmission of ultraviolet light in the UV-C region.

[0234] The cleaning machine station 300 of the present invention includes the sterilizing unit 450 , and thus has the advantage that even when the dust sucked from the dust cylinder 220 of the cleaning machine 200 is stored in the capturing unit 370 for a long time, the cleaning machine station 300 can be managed hygienically.

[0235] In addition, although Fig.10 Although not shown in the figure, the fixing unit 330 and the door unit 340 may be arranged adjacent to the coupling portion 320. For this, reference may be made to the above description. Figures 6 to 8 The explanation is given.

[0236] The cleaner workstation 300 also includes a capture portion 370 .

[0237] The capture part 370 is detachably coupled to the chamber 360. The capture part 370 is provided with a storage space to collect dust sucked from the inside of the dust canister 220 by the dust collecting motor 391.

[0238] Fig.11 3 is a perspective view for explaining the capture unit 370 in the cleaning machine workstation 300 of the embodiment of the present invention. Fig.12 3 is a diagram in which the structure included in the capture portion 370 and the structure coupled to the capture portion 370 are separated and expanded. Fig.13 yes Fig.11 X-X' cross-sectional view.

[0239] Reference Figures 11 to 13 The capture portion 370 may include a capture portion body 371 , a capture portion inner wall 372 and a cyclone separation portion 373 .

[0240] The capture part body 371 forms the appearance of a space for storing dust. In an optional embodiment, the capture part body 371 is generally hexahedral. In another optional embodiment, the capture part body 371 is generally cylindrical.

[0241] A transparent panel 3714 may be disposed on the upper surface 3711 of the capturing portion body 371 .

[0242] When the capturing unit 370 is coupled to the cavity 360, the transmissive panel 3714 is disposed at a position corresponding to the position where the sterilizing unit 450 is disposed. That is, when the capturing unit 370 is inserted into the cavity 360, the sterilizing unit 450 and the transmissive panel 3714 are disposed opposite to each other.

[0243] The transmissive panel 3714 is made of a material that allows the sterilizing light emitted from the sterilizing unit 450 to pass through the inside of the capturing unit body 371. As an example, the transmissive panel 3714 can be made of PMMA (Poly methyl methacrylate).

[0244] A capture part hinge 3715 may be disposed on one side of a corner of the lower surface 3712 of the capture part body 371. When the lower surface 3712 of the capture part body 371 rotates with the capture part hinge 3715 as an axis, the interior of the capture part body 371 may be opened. Thus, the user may discharge the dust collected in the capture part body 371 to the outside for cleaning.

[0245] An inlet 3711a is formed on the upper surface 3711 of the capture part body 371 to allow air to flow in from the flow path. As an example, the inlet 3711a may be circular. The first flow path 381 is connected to the upper side of the inlet 3711a. Thus, air sucked in by the suction force of the dust collecting motor 391 flows into the capture part body 371. The inlet 3711a may be arranged on the upper side of the first storage space S1 described later.

[0246] The inlet cover 3716 is combined with the inlet 3711a. The inlet cover 3716 can be opened by the suction force of the dust collecting motor 391. That is, the inlet cover 3716 can be opened toward the inner space (specifically, the first storage space S1) of the capture part body 371. When the dust collecting motor 391 is not driven, the inlet cover 3716 keeps the inlet 3711a locked, and when the dust collecting motor 391 starts to drive, the inlet cover 3716 opens the inlet 3711a.

[0247] To this end, the inlet cover 3716 may include a unit for applying a restoring force in the direction of locking the inlet 3711a. The restoring force applying unit may be, for example, an elastic member, a torsion spring, etc. With such a structure, as long as the attraction force is not applied, the inlet cover 3716 always locks the inlet 3711a, preventing the odor, pollution, bacteria, etc. generated inside the capture unit 370 from spreading to the first flow path 381.

[0248] A handle 3718 may be disposed on the front (or front side) of the capture unit body 371. The handle 3718 is a member held by the user to draw the capture unit 370 out of the cavity 360. The user holds the handle 3718 and pulls the capture unit 370 forward, so that the capture unit 370 can be easily drawn out of the cavity 360.

[0249] The capture part body 371 is provided with a finger groove 3717 so that the user can easily hold the handle 3718. The finger groove 3717 is formed to a degree that the user's finger can be inserted. The finger groove 3717 is formed in a shape that the capture part body 371 is recessed toward the inner space of the capture part 370. With such a structure, the handle 3718 is prevented from excessively protruding to the outside of the capture part body 371, which is conducive to the miniaturization of the cleaning machine workstation 300.

[0250] The capture portion inner wall 372 may be disposed inside the storage space of the capture portion body 371. The capture portion inner wall 372 may divide the storage space of the capture portion body 371 into two separate spaces. The capture portion inner wall 372 may be disposed in a direction perpendicular to the ground.

[0251] The capture portion inner wall 372 may be provided with a lattice net 3721. For example, the lattice net 3721 may constitute a part of the capture portion inner wall 372. That is, when air flows from one side of the divided storage space to the other side, the air may pass through the lattice net 3721.

[0252] In addition, the internal storage space of the capture portion 370 is divided into a first storage space S1 and a second storage space S2 by the capture portion inner wall 372 .

[0253] The first storage space S1 may be provided with a compression unit 410 described later. The second storage space S2 may be provided with a cyclone separation unit 373. Air sucked from the outside through the first flow path 381 first flows into the first storage space S1 and flows to the second storage space S2 through the mesh net 3721.

[0254] Thus, relatively large dust can be filtered out by the mesh net 3721. The filtered large dust is gathered at the lower side of the first storage space S1 and stored.

[0255] A plurality of cyclone separation parts 373 may be provided. For example, two or more conical or cylindrical cyclone separation part bodies may be provided.

[0256] Each cyclone separation part body includes an inflow body 3731 for the air passing through the grid net 3721 to flow in. Each cyclone separation part body also includes an outflow body 3732 connected to the exhaust flow path 374. The exhaust flow path 374 is a flow path connected to the dust collecting motor 391 side, and is a flow path that constitutes a part of the second flow path 382 described later.

[0257] Air is sucked from the outflow body 3732 by the suction force applied to the discharge flow path 374, and a cyclone separation flow is generated toward the inflow body 3731. By such a cyclone separation flow, fine dust can be filtered from the air that has passed through the mesh net 3721.

[0258] From another point of view, the first receiving space S1 is a space for first receiving and storing the sucked dust, and can also be defined as a dust collecting space S1.

[0259] The grid net 3721 may be disposed at one side of the dust collection space S1. The grid net 3721 may be formed by a portion of the wall surface defining the dust collection space. That is, the grid net 3721 may form a portion of the outer wall surrounding the dust collection space S1.

[0260] The cyclone separation unit 373 filters dust from the air flowing from the dust collection space S1 through the mesh net 3721 .

[0261] The cleaner station 300 may include a flow path portion 380 .

[0262] Re-reference Fig.10 The flow path portion 380 is defined as a passage for the air and foreign matter discharged from the dust canister 220 of the cleaning machine 200 to flow. The flow path portion 380 may include a first flow path 381 connecting the dust canister 220 and the capture portion 370 and a second flow path 382 connecting the capture portion 370 and the dust collecting motor 391.

[0263] The first flow path 381 may be disposed at the rear side of the joint surface 321. The first flow path 381 may represent a space for allowing air to flow between the dust cylinder 220 of the cleaning machine 200 and the capturing portion body 371. For example, the first flow path 381 may be a space formed by being surrounded by a structure. For example, the first flow path 381 may be an inner space of a hollow tube.

[0264] The first flow path 381 may include a first region 381a communicating with the inner space of the dust canister 220 when the cleaning machine 200 is coupled to the cleaning machine workstation 300 and the dust canister and the hole 321a are opened, and a second region 381b communicating with the first region 381a and the dust separation unit 213 (see FIG. Figure 8 ).

[0265] Therefore, when the dust collecting motor 391 is operated, the dust in the dust tube 220 of the cleaning machine 200 flows toward the capturing portion body 371 through the first flow path 381 .

[0266] The second flow path 382 may connect the capture part 370 and the dust suction module 390 . That is, the air from which the dust is separated by passing through the capture part 370 is guided to the dust collecting motor 391 through the second flow path 382 .

[0267] The second flow path 382 is a space formed between the capture part body 371 and the dust suction module 390 for air flow. The second flow path 382 may be formed to surround a structure. A portion of the second flow path 382 may be formed inside the capture part body 371. The portion has the same structure as the exhaust flow path 374. The exhaust flow path 374 may be arranged on the front side of the capture part body 371 (see Fig.13 ).

[0268] The cleaning machine workstation 300 may include a dust suction module 390 .

[0269] Re-reference Fig.10 The dust suction module 390 may include a dust collecting motor 391. The dust collecting motor 391 may be disposed at the lower portion of the capture portion 370. The dust collecting motor 391 may generate suction force in the flow path portion 380. Thus, suction force that can suck dust is provided to the inside of the dust cylinder 220 of the cleaning machine 200.

[0270] The dust suction module 390 may further include a high efficiency filter (not shown). The high efficiency filter may be disposed at the rear end of the dust collecting motor 391 (based on the air flow path), thereby exhausting clean air to the outside of the housing 310.

[0271] The cleaning machine station 300 may include a compression part 410. The compression part 410 is a structure for compressing dust collected in the capture part 370.

[0272] Reference Fig.12 and Fig.13 The compression part 410 is disposed inside the storage space of the capture part body 371. More specifically, the compression part 410 is disposed inside the first storage space S1 of the capture part body 371.

[0273] The compression part 410 is movably disposed inside the capture part body 371. The compression part 410 moves in a direction to compress the dust collected inside the first storage space S1. In an optional embodiment, the compression part 410 is rotatably disposed in the first storage space S1. In another optional embodiment, the compression part 410 is disposed in the first storage space S1 in a manner that allows linear movement.

[0274] Next, as a representative example (refer to Fig.12 , Fig.13 ) An embodiment in which the compression unit 410 rotates and moves to compress dust is described.

[0275] The compression unit 410 rotates around an axis disposed in the longitudinal direction inside the capture unit body 371 (the first storage space S1 ). More specifically, the compression unit 410 may include a rotation axis member 411 , a fixing plate 412 , and a rotation plate 413 .

[0276] The rotating shaft member 411 may be disposed vertically in the first storage space S1 inside the capture unit body 371. The rotating shaft member 411 receives power from a compression motor 420 to be described later and rotates. The central axis of the rotating shaft member 411 may be coaxial with the central axis of the first storage space S1.

[0277] The lower end of the rotating shaft member 411 is connected to the bottom surface of the first storage space S1 and supported. The upper end of the rotating shaft member 411 is separated from the inlet 3711a by a predetermined distance so as not to hinder the opening of the inlet cover 3716 (see Fig.14 ).

[0278] The fixing plate 412 may be fixed to one side inside the capture part 370 and arranged. More specifically, the fixing plate 412 is arranged in the first storage space S1 in the up-down direction and may be fixed to one side of the inner circumference of the capture part body 371 forming the first storage space S1 and combined. The fixing plate 412 may be a square plate. The fixing plate 412 may be arranged on the opposite side of the grid net 3721.

[0279] The fixed plate 412 completely covers or covers a certain portion of the first receiving space S1 , and together with the rotating plate 413 , compresses dust pushed and moved by the rotation of the rotating plate 413 .

[0280] The rotating plate 413 may be connected to the outer circumference of the rotating shaft member 411 and rotate together with the rotating shaft member 411. More specifically, the rotating plate 413 is arranged between the inner circumference of the capturing portion body 371 constituting the first storage space S1 and the outer circumference of the rotating shaft member 411 and rotates.

[0281] The shape of the rotating plate 413 is basically a square plate, and can be deformed into a shape that avoids interference with other components arranged in the first storage space S1. For example, when the inlet cover 3716 opens the inlet 3711a, a cut-off portion is formed at the upper end of the rotating plate 413 so as not to be interfered by the rotation radius of the inlet cover 3716 (see Fig.14 ).

[0282] The rotating plate 413 can rotate forward and reversely. Based on the state of observing the first storage space S1 from the upper side (ie, the state of observing the capture portion 370 from the upper side downward), clockwise rotation is defined as forward rotation, and counterclockwise rotation is defined as reverse rotation.

[0283] When the rotating plate 413 rotates forward, one side of the rotating plate 413 contacts one side of the fixed plate 412 to compress the dust. Similarly, when the rotating plate 413 rotates reversely, the other side of the rotating plate 413 contacts the other side of the fixed plate 412 to compress the dust. That is, a part of the compressed dust exists around one side of the fixed plate 412, and the remaining dust exists around the other side of the fixed plate 412.

[0284] The compression part 410 may further include a cleaning member 414 .

[0285] Reference Fig.13 The cleaning member 414 is coupled to the end of the rotating plate 413 on the opposite side to the rotating shaft member 411. That is, one end of the rotating plate 413 is coupled to the rotating shaft member 411 and the other end is coupled to the cleaning member 414.

[0286] The cleaning member 414 is arranged to rotate together with the rotating plate 413 in a state of being in contact with the mesh net 3721. More specifically, one side edge of the cleaning member 414 is arranged in contact with one side of the mesh net 3721 (see Fig.14 ).

[0287] Thus, when the cleaning member 414 rotates together with the rotating plate 413, it can scrape the mesh 3721 while rotating, and remove foreign matter stuck on the mesh 3721. The cleaning member 414 can be, for example, a scrubber made of rubber.

[0288] Fig.14 3 is a diagram showing the direction in which air is sucked in a state in which the capture portion 370 is inserted into the housing 310 .

[0289] The air flowing into the first storage space S1 of the capturing portion body 371 through the first flow path 381 separates large dust particles from the air as it passes through the mesh net 3721 , and the air from which the large dust particles are separated flows into the second storage space S2 .

[0290] Thereafter, the air flowing into the second storage space S2 is further separated into fine dust as it passes through the cyclone separation unit 373 , and the air from which the fine dust is separated flows into the exhaust flow path 374 provided in the capturing unit body 371 .

[0291] The air exhausted from the exhaust flow path 374 passes through the pre-filter 470 and flows toward the dust collecting motor 391 .

[0292] Here, the pre-filter 470 is a component disposed between the dust collecting motor 391 and the capturing part 370, and filters dust again in the air flowing to the dust collecting motor 391 to protect the dust collecting motor 391. The pre-filter 470 is disposed on the second flow path 382, ​​and more specifically, is disposed on the outside of the exhaust flow path 374 provided in the capturing part body 371 to filter the air exhausted from the capturing part body 371.

[0293] The cleaning machine workstation 300 may include a compression motor 420 and a power transmission part 430. The compression motor 420 and the power transmission part 430 are members for generating power for moving the compression part 410 and transmitting the power to the compression part 410.

[0294] The compression motor 420 and the power transmission unit 430 are arranged outside the storage space of the capture unit body 371 .

[0295] The compression motor 420 generates power for rotating the compression unit 410. The compression motor 420 is composed of a motor that can rotate in the forward direction and the reverse direction. In other words, as the compression motor 420, a motor that can rotate in both directions is used.

[0296] Thus, the rotating plate 413 can rotate forward and reversely. As the rotating plate 413 rotates forward and reversely, compressed foreign matter is accumulated on both side surfaces of the fixed plate 412 .

[0297] In this way, in order to allow the compression motor 420 to rotate forward / reverse, a synchronous motor may be used as the compression motor 420. Such a synchronous motor can rotate forward / reverse by the motor itself, and when the compression motor 420 rotates in one direction, if the force applied to the compression motor 420 becomes greater than a set value, the rotation of the compression motor 420 is converted to the other direction.

[0298] At this time, the force applied to the compression motor 420 is a resistance (torque) generated as the rotating plate 413 presses the dust. When the resistance reaches a set value, the rotation direction of the compression motor 420 is changed.

[0299] The rest of the technology regarding the synchronous motor is well known in the field of motor technology, and thus a detailed description thereof will be omitted.

[0300] The power transmission unit 430 is disposed between the compression unit 410 and the compression motor 420 and transmits power generated by the rotation of the compression motor 420 to the compression unit 410 .

[0301] More specifically, the power delivery part 430 includes a driving gear 431 rotated by the power of the compression motor 420. The driving gear 431 may be connected to a motor shaft of the compression motor 420.

[0302] The power transmission unit 430 further includes a transmission gear 432 which is gear-engaged with the driving gear 431 and receives the power of the compression motor 420 from the driving gear 431 and transmits the power to the compression unit 410 .

[0303] Regarding the driving gear 431, reference will be made to Fig.16 This will be described later. First, the transmission gear 432 is described as follows.

[0304] Fig.15 It is an enlarged view of the driving gear 431 and the transmission gear 432.

[0305] Reference Fig.15 and Fig.12 The transmission gear 432 can be connected to the rotating shaft component 411 of the compression part 410. The transmission gear 432 is provided with gear teeth 4322 that mesh with the driving gear 431 at the lower periphery. The transmission gear shaft 4321 that is coaxially connected to the rotating shaft component 411 is provided at the upper center of the transmission gear 432.

[0306] The transmission gear shaft 4321 can be inserted into the storage space of the capture part body 371 through a hole formed in the lower surface of the capture part body 371. The transmission gear shaft 4321 is configured to be inserted into the hollow formed in the rotating shaft member 411. That is, the diameter of the outer circumference of the transmission gear shaft 4321 can be smaller than the diameter of the outer circumference of the rotating shaft member 411.

[0307] The transmission gear shaft 4321 and the rotation shaft member 411 may be formed with instrumental members that mesh with each other in such a manner that they rotate at the same angular velocity. For example, the instrumental structure may be a protrusion and groove member.

[0308] In addition, the driving gear 431 may be coupled to the housing 310, and the transmission gear 432 may be coupled to the capture part 370. The driving gear 431 and the transmission gear 432 are gear-engaged with each other, and can be detached from the housing 310 when only the transmission gear 432 is coupled to the capture part 370.

[0309] That is, the compression motor 420 and the driving gear 431 are rotatably coupled to the chamber 360 and cannot be separated from the chamber 360 (housing 410). On the contrary, the transmission gear 432 is rotatably coupled to the capture portion 370 and is detachable from the chamber 360 (housing 310).

[0310] With such a structure, the user only needs to push the capture portion 370 into the cavity 360 to naturally cause the transmission gear 432 and the driving gear 431 to mesh with each other.

[0311] When the capture part 370 is inserted into the cavity 360 , the power of the compression motor 420 is transmitted to the compression part 410 through the driving gear 431 and the transmission gear 432 .

[0312] When the capture part 370 is drawn out of the cavity 360, the gear meshing of the transmission gear 431 and the driving gear 432 can be released. Then, when the transmission gear 432 is separated from the rotating shaft member 411 and the lower surface of the capture part body 371 is opened, the user can easily remove the dust collected in the storage space of the capture part body 371.

[0313] Fig.16 This is a diagram for explaining a pattern 4314 formed on the driving gear 431 .

[0314] Reference Fig.16 The driving gear 431 may include a gear body 4311 , a shaft connecting portion 4312 and gear teeth 4313 .

[0315] The gear body 4311 may form the appearance of the driving gear 431. Gear teeth 4313 are formed on the upper portion of the gear body 4311 to mesh with the gear teeth 4322 of the transmission gear 432. A pattern 4314 of alternating and continuous protrusions and grooves is formed around the lower side of the gear body 4311.

[0316] The sizes of the upper diameter of the gear body 4311 where the gear teeth 4313 are configured and the lower diameter of the gear body 4311 where the pattern 4314 is formed may be different from each other.

[0317] A shaft connection portion 4312 connected to the motor shaft of the compression motor 420 is formed at the center of the gear body 4311. The shaft connection portion 4312 is formed in a cylindrical shape inside the gear body 4311. The shaft connection portion 4312 is formed with a hole having a shape corresponding to the motor shaft for the motor shaft to be inserted. Thus, when the compression motor 420 rotates, the driving gear 431 also rotates together. A plurality of ribs 4315 are radially arranged on the outer peripheral surface of the shaft connection portion 4312 to support the shape of the shaft connection portion 4312.

[0318] The pattern 4314 formed on the driving gear 431 is formed so that the widths of the protrusions and the widths of the grooves adjacent to each other are different from each other.

[0319] The protrusions and grooves formed in the pattern 4314 can be defined by dividing the phases according to the size of the formed width. At this time, the order of configuring the phases of the above-mentioned pattern 4314 is different from each other with respect to the first direction and the second direction related to the periphery of the gear body 4311, and the second direction is the direction opposite to the above-mentioned first direction.

[0320] More specifically, for example, the description is as follows.

[0321] like Fig.16 In the embodiment shown, four phases in pattern 4314 may be formed as one group. Here, the first phase and the third phase may be formed in a protrusion shape, and the second phase and the fourth phase may be formed in a groove shape. That is, the protrusions and the grooves may be formed alternately.

[0322] Here, the widths of the first to fourth phases may be different, and each phase may be divided according to the size of the above width. Fig.16 Taking the illustrated embodiment as an example, a protrusion with a width of dt_d1 mm is defined as a first phase, a groove with a width of dt_d2 mm is defined as a second phase, a protrusion with a width of dt_d3 mm is defined as a third phase, and a groove with a width of dt_d4 mm is defined as a fourth phase.

[0323] The arrangement order of each phase is repeatedly arranged in the order of 1-2-3-4 when the gear body 4311 of the driving gear 431 is moved in the first direction d1. Therefore, when the gear body 4311 of the driving gear 431 is moved in the second direction d2 opposite to the first direction d1, the phases are repeatedly arranged in the order of 4-3-2-1.

[0324] Thus, by configuring the directional pattern 4314 formed on the driving gear 431, the compression state sensing unit 440 described later can sense whether the driving gear 431 is currently rotating in the first direction d1 or the second direction d2. The rotation of the driving gear 431 is connected to the rotation of the compression unit 410, so the rotation direction of the compression unit 410 is determined by the rotation direction of the driving gear 431.

[0325] In addition, the angle at which the driving gear 431 is rotated can be calculated based on the number of patterns 4314 sensed during the rotation of the driving gear 431. The rotation angle calculated in the embodiment of the present invention is calculated based on the number of patterns 4314 sensed by the compression state sensing unit 440, and has nothing to do with the rotation speed of the driving gear 431 or the compression unit 410, which will be described later.

[0326] That is, when calculating the rotation angle, it is not calculated indirectly based on the rotation speed, but the rotation angle is directly calculated by sensing the physical rotation state of the instrumental structure of the driving gear 431, so there is an advantage of more accurately calculating the rotation angle.

[0327] In addition, in a representative embodiment of the present invention, the shape pattern for sensing the rotation direction and angle of the compression part 410 is formed on the driving gear 431 as an example, but in another optional embodiment, the above pattern can also be formed on the transmission gear 432.

[0328] In the case where the transmission gear 432 forms the above-mentioned pattern, the transmission gear 432 can be separated from the housing 310 together with the capture portion 370. This facilitates maintenance and repair in the event of an error in sensing the above-mentioned pattern.

[0329] Fig.17 4 is a diagram showing the arrangement relationship between the driving gear 431 and the compression state sensing unit 440. Fig.18 It is a diagram for explaining the sensing principle of the compression state sensing unit 440 .

[0330] The cleaning machine workstation 300 may include a compression state sensing portion 440 .

[0331] The compression state sensing unit 440 is disposed adjacent to the driving gear 431. The compression state sensing unit 440 senses the rotation direction of the compression unit 410 and the rotation angle thereof in the rotation direction by using the pattern 4314 formed on the driving gear 431.

[0332] As an example, the compression state sensing unit 440 may be composed of a photointerrupter. In this case, the compression state sensing unit 440 is configured such that the pattern 4314 of the driving gear 431 is sandwiched between the light receiving unit and the light emitting unit. As is well known, a photointerrupter is a sensor that integrates a photoconductive diode and a phototransistor, wherein the light receiving unit of the photointerrupter is composed of a phototransistor and the light emitting unit is composed of a photoconductive diode.

[0333] Reference Fig.17 and Fig.18 It can be seen that when the protrusion pattern (first phase or third phase) is arranged between the light receiving part and the light emitting part, the transmission of infrared light is blocked. When the groove pattern (second phase or fourth phase) is arranged between the light receiving part and the light emitting part, infrared light passes through the bottom of the phototransistor.

[0334] When the infrared light is transmitted, a high signal (or an on signal) is transmitted to the control unit 510 described later. When the infrared light is blocked, a low signal (or an off signal) is transmitted to the control unit 510. The control unit 510 can determine the phase of the pattern 4314 currently being sensed according to the counting number of the transmitted signal.

[0335] Fig.19 is a block diagram of a cleaning machine workstation 300 according to an embodiment of the present invention.

[0336] Reference Fig.19 The cleaning machine workstation 300 may further include a control unit 510 for controlling various components of the cleaning machine workstation 300. The control unit 510 may be mounted on a printed circuit substrate.

[0337] The control unit 510 may include all kinds of devices that can process data, such as a processor. Here, a "processor" refers to a data processing device that is a circuit having a physical structure and is built into hardware, for example, in order to execute a function represented by a code or command included in a program. Thus, as an example of a data processing device built into hardware, it may include a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an ASIC (application-specific integrated circuit), an FPGA (field programmable gate array), and other processing devices, but the scope of the present invention is not limited to this.

[0338] When the coupling sensor 325 senses the coupling of the cleaning machine 200, the coupling sensor 325 transmits a signal indicating that the cleaning machine 200 is coupled to the coupling portion 320 to the control portion 510. At this time, the control portion 510 receives the signal from the coupling sensor 325 and determines that the cleaning machine 200 is coupled to the coupling portion 320.

[0339] In addition, when power is supplied from the charging terminal 328 to the battery 240 of the cleaning machine 200 , the control unit 510 determines that the cleaning machine 200 is coupled to the coupling unit 320 .

[0340] When it is determined that the cleaning machine 200 is coupled to the coupling portion 320 , the control portion 510 controls the fixing portion motor 580 to be driven to rotate in the forward direction, thereby fixing the cleaning machine 200 to the coupling portion 320 .

[0341] The cleaning machine workstation 300 may further include a fixing sensor 570 that transmits a signal that the cleaning machine 200 is coupled to the coupling part 320 to the control part 510 when the fixing member 331 or the fixing part chain 335 moves to a prescribed fixing location FP1 .

[0342] The control unit 510 receives a signal indicating that the cleaning machine 200 is fixed from the fixing sensor 570 and determines that the cleaning machine 200 is fixed to the coupling unit 320. When it is determined that the cleaning machine 200 is fixed, the control unit 510 controls the fixing unit motor 580 to stop driving.

[0343] In addition, when the dust can 220 is emptied, the control unit 510 controls the fixing unit motor 580 to rotate in the reverse direction, thereby releasing the fixing of the cleaning machine 200 and the coupling unit 320 .

[0344] The control unit 510 controls the door motor 342 to rotate in the forward direction, thereby opening the door 341 of the cleaning station 300 .

[0345] The cleaning machine workstation 300 may further include a door opening and closing sensor 560 . When the door 341 or the door arm 343 reaches a predetermined opening position DP1 , the door opening and closing sensor 560 transmits a signal indicating that the door 341 is opened to the control unit 510 .

[0346] The control unit 510 may receive a signal from the door opening / closing sensor 560 and determine that the door 341 is in an open state. When it is determined that the door 341 is opened, the control unit 510 controls to stop driving of the door motor 342.

[0347] In addition, when the dust canister 220 is emptied, the control unit 510 controls the door motor 342 to rotate in the reverse direction to lock the door 341 .

[0348] The control unit 510 controls the driving of the cover opening motor 352 to open the discharge cover 222 of the cleaning machine 200 .

[0349] The cleaning machine workstation 300 may further include a cover opening sensor 520 , which transmits a signal indicating that the discharge cover 222 is opened to the control unit 510 when the push protrusion 351 reaches a prescribed opening position CP1 .

[0350] The control unit 510 may receive a signal from the cover opening sensor 520 and determine that the discharge cover 222 is in an opened state. When it is determined that the discharge cover 222 is opened, the control unit 510 controls to stop driving of the cover opening motor 352.

[0351] The control unit 510 can control the sterilization unit 450. For example, the control unit 510 can turn on the light source of the sterilization unit 450 after the capture unit 370 captures dust or at a predetermined time interval to sterilize viruses or microorganisms in the capture unit 370.

[0352] The control unit 510 can control the driving of the dust collecting motor 391. The control unit 510 controls the driving of the dust collecting motor 391 for a predetermined time, so that the dust inside the dust tube 220 is sucked into the capturing unit 370.

[0353] The control unit 510 can control the compression motor 420. The control unit 510 controls the compression motor 420 to be driven more than a predetermined number of times and / or for more than a predetermined time, so that the dust collected in the capture unit 370 is compressed.

[0354] When it is determined that the cleaning machine 200 is coupled to the coupling portion 320, the control unit 510 controls to drive the compression motor 420. The control unit 510 controls to drive the compression motor 420 after the dust collection is completed and the driving of the dust collection motor 391 stops.

[0355] The control unit 510 may calculate the amount of dust collected in the capture unit 370. In the embodiment of the present invention, the amount of dust collected may be calculated based on the rotation angle of the driving gear 431 or the compression unit 410 sensed by the compression state sensing unit 440.

[0356] As described above, the compression state sensing unit 440 senses the change of the pattern 4314 of the driving gear 431 to generate an on / off signal. The on signal corresponds to a high signal, and the off signal corresponds to a low signal.

[0357] The control unit 510 receives the signal transmitted from the compression state sensing unit 440 and determines the phase of the pattern 4314 of the current driving gear 431 .

[0358] The phase can be determined by the number of signals counted according to the sensing signal and sensing resolution of the compression state sensing unit 440. Fig.16 In the embodiment of the present invention, the number of counts of the high signal of the fourth phase is greater than the number of counts of the high signal of the second phase. Fig.16 In an embodiment, the count number of the low signal of the third phase is greater than the count number of the low signal of the first phase.

[0359] Thus, the control unit 510 may determine the number of phase changes sensed by the compression state sensing unit 440 , and may calculate the rotation angle of the driving gear 431 based on the number of phase changes.

[0360] For a more specific description, it is assumed that N mutually different phases constitute one set, and the number of such sets is M in the driving gear 431 .

[0361] When the driving gear 431 rotates through one group, the rotation angle obtained is 360 / M (°). When this is divided by N again, the approximate rotation angle corresponding to one phase can be obtained.

[0362] like Fig.16 As shown in the embodiment of FIG. 1 , when N=4 (Phase) and M=30 (Set), the rotation angle of one set of phases is calculated to be 12°, and the rotation angle of one phase is calculated to be about 3°. At this time, the widths of the phases are different from each other and the error generated is not large, so the same rotation angle can be applied to the rotation angle of one phase.

[0363] The control unit 510 regards the forward rotation and the reverse rotation of the compression motor 420 as one cycle, and calculates the dust collection amount using the average value of the rotation angle of the forward rotation and the rotation angle of the reverse rotation of the compression unit 410.

[0364] When the compression motor 420 rotates forward (clockwise), the driving gear 431 rotates in the first direction d1 (clockwise), and when the compression motor 420 rotates reverse (counterclockwise), the driving gear 431 rotates in the second direction d2 (counterclockwise).

[0365] When the driving gear 431 rotates in the first direction d1, the transmission gear 432 meshed with the driving gear 431 rotates in the second direction d2, and the rotating plate 413 of the compression part 410 coaxially connected to the transmission gear 432 rotates in the second direction d2. The transmission gear 432 and the rotating shaft component 411 of the compression part 410 are coaxially connected, so when the compression motor 420 rotates in the positive direction, that is, the clockwise direction, the rotating plate 413 rotates in the counterclockwise direction.

[0366] According to the same principle, when the driving gear 431 rotates in the second direction d2, the transmission gear 432 rotates in the first direction d1, and the rotating plate 413 of the compression unit 410 also rotates in the first direction d1. That is, when the compression motor 420 rotates in the reverse direction, that is, counterclockwise, the rotating plate 413 rotates in the clockwise direction.

[0367] In addition, the clockwise direction cw and the counterclockwise direction ccw described in the specification of the present invention are based on a state in which the cleaning machine station 300 is viewed from above.

[0368] As described above, the rotation angle of the compression unit 410 is calculated from the number of phase changes of the pattern 4314 formed on the driving gear 431. When the forward rotation angle of the compression unit 410 calculated by the control unit 510 is calculated to be 80° and the reverse rotation angle is calculated to be 70°, the control unit 510 determines the rotation angle of the compression unit 410 to be 75°, which is the average value.

[0369] In this way, when the average value of the forward / reverse rotation angles is determined as the rotation angle of the compression unit 410, the reliability of calculating the rotation angle can be further improved.

[0370] The control unit 510 may calculate the dust collection amount as a percentage according to the rotation angle of the compression unit 410. For example, when the rotation angle of the compression unit 410 is 180°, the calculated dust collection amount is 50%.

[0371] The control part 510 divides the dust collection amount to match the preset level.

[0372] For example, when the rotation angle of the compression unit 410 is 234 degrees or more, the dust collection amount is divided into the first level corresponding to the "level of no collected dust".

[0373] For example, when the rotation angle of the compression unit 410 is greater than 180° and less than or equal to 234°, the dust collection amount is divided into two levels.

[0374] For example, when the rotation angle of the compression unit 410 is greater than 126° and less than or equal to 180°, the dust collection amount is divided into three levels.

[0375] For example, when the rotation angle of the compression unit 410 is greater than 72° and less than or equal to 126°, the dust collection amount is divided into four levels.

[0376] For example, when the rotation angle of the compression unit 410 is 72° or less, the dust collection amount is divided into five stages corresponding to the “stage where dust is full”.

[0377] The above-mentioned dust collection amount level division criteria and the number of divided levels are merely examples and can be appropriately changed according to the design.

[0378] When the calculated dust collection amount is equivalent to the last gear among the preset multiple gears, the control unit 510 controls so that the dust collection motor 391 is not driven. The above-mentioned last gear is, for example, equivalent to the dust collection amount 5 gear described above. At this time, even if the cleaning machine 200 is connected to the connecting part 320, the control unit 510 can also control the dust collection motor 391 not to drive.

[0379] The control unit 510 may control the display unit 530 . The control unit 510 controls the display unit 530 to display various information related to the driving of the cleaning machine station 300 .

[0380] For example, the above information may include the emptying progress status of the dust cylinder 220 of the cleaning machine 200, the charging level of the cleaning machine 200, the guidance of the components currently being driven, the compression level of dust, etc.

[0381] The control unit 510 may display the notification on the display unit 530 in a preset plurality of levels according to the amount of dust collected in the capture unit 370. For example, the control unit 510 may display the notification on the dust compression state in a plurality of levels according to the amount of dust collected.

[0382] At the same time, the control unit 510 displays the non-driving state of the dust collecting motor 391 on the display unit 530 to remind the user to remove the dust collected in the capturing unit 370 at an appropriate time.

[0383] Re-reference Fig.19 The cleaning machine workstation 300 may further include a memory 540. The memory 540 may store an application program for driving the cleaning machine workstation 300 and various related data.

[0384] The preset values ​​related to the driving of the cleaning machine workstation 300 described in this specification may be stored in the memory 540 .

[0385] The memory 540 may include a magnetic storage medium or a flash storage medium, but the scope of the present invention is not limited thereto. Such a memory 540 may include a built-in memory and / or an external memory, and may include a volatile memory such as DRAM, SRAM or SDRAM, a non-volatile memory such as OTPROM (one time programmable ROM), PROM, EPROM, EEPROM, mask ROM, flash ROM, NAND flash memory or NOR flash memory, a flash drive such as SSD, CF (compact flash) card, SD card, micro SD card, mini SD card, Xd card or memory stick, or a storage device such as HDD.

[0386] The memory 540 may be included in the control unit 510 or formed as a separate component.

[0387] The cleaning machine workstation 300 may further include an input unit 550. The input unit 550 generates key input data input by the user to control the operation of the cleaning machine workstation 300. To this end, the input unit 550 is composed of a key pad, a dome switch, a touch panel (static pressure / static electricity), etc. In particular, when the touch panel and the display unit 530 form a layer structure with each other, this can be called a touch screen.

[0388] The input unit 550 and / or the display unit 530 may be disposed on the upper surface 313 of the housing 310 .

[0389] Fig. 20 An example in which notification on the dust compression state is guided through the display portion 530 is shown.

[0390] like Fig. 20 As shown in the embodiment of FIG. 5 , the control unit 510 displays the notification about the dust compression state on the display unit 530 in three levels. Fig. 20 The dust collection amount corresponding to each notification file shown in the figure is only an example, and it can be changed appropriately. Fig. 20 The component called 'dust cylinder' corresponds to the capturing portion 370 described in this specification.

[0391] In this way, when the notification about the dust compression state is displayed in multiple levels, the user can know the extent of dust currently collected in the capture unit 370. In addition, the user can remove the dust at an appropriate time according to the mark even before the capture unit 370 is full of dust. For example, the user displays the first notification ( Fig. 20 When the notification is 60% full in the example, the dust in the capture portion 370 can be cleared.

[0392] Next, a dust collection method performed by the cleaning machine workstation 300 as one embodiment of the present invention will be described.

[0393] Fig.21 is a sequence diagram showing the procedure of the dust collection method of the cleaning machine workstation 300 according to an embodiment of the present invention, Fig. 22 is Fig.21 The embodiment of the present invention includes a diagram of the action sequence of each motor in the cleaning machine workstation 300, Fig.23 It is used to explain more specifically Fig.21 FIG. 4 is a diagram of the operation of the compression unit 410 performed in the dust compression step (S600).

[0394] Reference Fig.21, the dust collection method of the cleaning machine workstation 300 includes a dust cartridge combining step (S100).

[0395] This step ( S100 ) is a step of coupling the dust cylinder 220 of the cleaning machine 200 to the housing 310 (specifically, the coupling part 320 ) of the cleaning machine workstation 300 by the user.

[0396] In an alternative embodiment, the dust canister 220 is coupled to the coupling portion 320 in a state of being coupled to the cleaning machine 200. In another alternative embodiment, the dust canister 220 is coupled to the coupling portion 320 in a state of being separated from the cleaning machine 200.

[0397] In this step (S100), the combination sensor 325 can sense the combination of the cleaning machine 200. The combination sensor 325 can transmit a signal that the cleaning machine 200 is combined with the combination part 320 to the control part 510. At this time, the control part 510 receives the signal of the combination sensor 325 and determines that the cleaning machine 200 is combined with the combination part 320.

[0398] In addition, when power is supplied to the battery 240 of the cleaning machine 200 at the charging terminal 328 , the control unit 510 determines that the dust canister 220 of the cleaning machine 200 is coupled to the coupling unit 320 .

[0399] In an optional embodiment, the combination sensor 325 and the charging terminal 328 may be used simultaneously or either one of them may be used to determine whether the dust canister 220 is combined or not.

[0400] The dust collection method of the cleaning machine workstation 300 may further include a dust canister fixing step ( S200 ).

[0401] This step (S200) is performed after the dust canister 220 of the cleaning machine 200 is coupled to the coupling portion 320. When the dust canister 220 is fixed to the coupling portion 320, shaking of the dust canister 220 can be prevented during the dust collection process performed later.

[0402] In this step ( S200 ), when it is determined that the dust canister 220 is coupled to the coupling portion 320 , the control portion 510 controls the fixing portion motor 580 to rotate forward, thereby fixing the dust canister 220 of the cleaning machine 200 to the coupling portion 320 .

[0403] The control unit 510 receives a signal from the fixing sensor 570 indicating that the dust can 220 is fixed to the connecting unit 320 and determines that the cleaning machine 200 is fixed to the connecting unit 320. When determining that the cleaning machine 200 is fixed, the control unit 510 controls the fixing unit motor 580 to stop driving.

[0404] More specifically, the control unit 510 controls the fixing unit motor 580 to be driven in the forward direction, so that the dust container 220 is fixed to the connecting unit 320 by the fixing component 331 .

[0405] At this time, when the fixing member 331 or the fixing part chain 335 moves to the dust canister fixing position FP1, the fixing sensor 570 transmits a signal indicating that the dust canister 220 is fixed to the coupling part 320 to the control part 510. Therefore, when receiving the signal from the fixing sensor 570, the control part 510 determines that the cleaning machine 200 is fixed to the coupling part 320, and controls the driving of the fixing part motor 580 to stop.

[0406] In another optional embodiment, the control unit 510 controls the fixing unit motor 580 to stop driving after the fixing unit motor 580 is driven in the forward direction during a preset fixed time tf. For example, the control unit 510 drives the fixing unit motor 580 in the forward direction for a fixed time tf of more than 4 seconds and less than 5 seconds, and then stops driving the fixing unit motor 580 (see Fig. 22 ).

[0407] The dust collecting method of the cleaning machine workstation 300 may further include a cover opening step ( S300 ).

[0408] This step ( S300 ) is performed after the dust container 220 is coupled to the coupling portion 320 of the housing 310 , and is a step in which the dust container body 221 is opened by rotating the discharge cover 222 to allow the interior of the housing 310 to communicate with the interior of the dust container 220 .

[0409] In an alternative embodiment, the cover opening step (S300) is performed after the dust tube fixing step (S200) described above.

[0410] In this step ( S300 ), the control unit 510 controls the cover opening motor 352 to rotate in the forward direction, thereby opening the discharge cover 222 of the cleaning machine 200 .

[0411] The control unit 510 receives the discharge cover opening signal from the cover opening sensor 520 and determines that the discharge cover 222 is in the open state. When it is determined that the discharge cover 222 is opened, the control unit 510 controls the cover opening motor 352 to stop driving.

[0412] More specifically, when the control unit 510 drives the cover opening motor 352 in the forward direction, the protrusion 351 is pushed away from the initial position and moved to a position where the coupling rod 222c is pressed. Therefore, the hook connection between the discharge cover 222 and the dust barrel body 221 is released by the movement of the coupling rod 222c, and the discharge cover 222 rotates to open one side of the dust barrel body 221.

[0413] In addition, before the push protrusion 351 presses the combining bar 222 c , the cover opening sensing part 520 transmits a signal indicating that the push protrusion 351 is located at the initial position to the control part 510 .

[0414] When the cover opening motor 352 is driven to push the protrusion 351 to start moving by pressing the coupling rod 222c, the cover opening sensor 520 transmits a signal indicating that the protrusion 351 is out of the initial position to the control unit 510. The control unit 510 receives such a signal and determines that the cover opening unit 350 is operating normally.

[0415] The control unit 510 drives the cover opening motor 352 in the forward direction during the cover opening time tc1 which is longer than the time required to press the coupling rod 222c, so that the discharge cover 222 is separated from the dust tube body 221. After that, the control unit 510 switches the rotation direction of the cover opening motor 352 to the reverse direction during the preset rotation direction switching time tc2, and then drives the cover opening motor 352 in the reverse direction during the preset protrusion return time tc3. As a result, the protrusion 351 can be pushed back to the initial position (see Fig. 22 ).

[0416] For example, the cover opening time tc1 and the projection return time tc3 may be set to a time of 4 seconds to 5 seconds. The above time may be set based on the moving distance and speed of the push projection 351. For example, the rotation direction switching time tc2 may be set to a time of 2 seconds to 3 seconds.

[0417] In addition, the control unit 510 may receive a signal from the cover opening sensor 520 indicating that the push protrusion 351 has returned to the initial position, and in this case, control the cover opening motor 352 to stop driving.

[0418] The dust collecting method of the cleaning machine workstation 300 may further include a door opening step ( S400 ).

[0419] This step (S400) is performed after the dust canister 220 is coupled to the coupling portion 320 of the housing 310, and is to open the door 341 disposed on the coupling portion 320. In an optional embodiment, the door opening step (S400) can be performed after the dust canister fixing step (S200) described above.

[0420] In an optional embodiment, the door opening step (S400) may be performed simultaneously with the lid opening step (S300) described above (see Fig. 22 ).

[0421] In this step ( S400 ), the control unit 510 controls the door motor 342 to rotate forward, thereby opening the door 341 of the cleaning station 300 .

[0422] More specifically, when the control unit 510 controls the door motor 342 to rotate forward, the door 341 rotates while opening the dust cylinder and the hole 321a. That is, in this step, the control unit 510 rotates the door 341 to open the dust cylinder and the hole 321a.

[0423] In addition, in an optional embodiment, the control unit 510 receives a signal from the fixing sensor 570 that the dust can 220 is fixed, and after a preset time, controls the door motor 342 to drive forward. For example, the control unit 510 drives the door motor 342 after a time of more than 0.5 seconds and less than 1.5 seconds after the dust can 220 is fixed.

[0424] With such a structure, the door 341 is opened after waiting for the time required for the push protrusion 351 to start applying pressure to the coupling rod 222c in the cover opening step (S300). In addition, the discharge cover 222 and the door 341 can be opened at a close timing. When the discharge cover 222 is opened after the door 341 is opened at the maximum angle, the discharge cover 222 impacts the door 341 and structural damage may occur. On the contrary, if the door 341 is not opened during the process of the push protrusion 351 applying pressure to the coupling rod 222c, the dust barrel body 221 cannot be opened. The structure described above can prevent such a problem.

[0425] In addition, the control unit 510 can rotate the door 341 in steps to open the dust cylinder and the hole 321a. More specifically, the control unit 510 rotates the door 341 to a preset first opening angle θ1, then stops the door 341 from rotating for a certain period of time, and then further rotates the door 341 to a preset second opening angle θ2 (refer to Fig. 22 ).

[0426] The sum of the first opening angle θ1 and the second opening angle θ2 becomes the maximum rotation angle of the door 341. The second opening angle θ2 may be greater than the first opening angle θ1. For example, the first opening angle θ1 may be greater than 25 degrees and less than 35 degrees. For example, the second opening angle θ2 may be greater than 45 degrees and less than 55 degrees.

[0427] As a result, when the cover opening step (S300) and the door opening step (S400) are performed, the discharge cover 222 of the dust canister 220 rotates to open one side of the dust canister body 221, and as the door 341 rotates, the dust canister and the hole 321a are opened, thereby connecting the internal space of the dust canister 220 and the internal space of the outer shell 310 (specifically, the first flow path 381).

[0428] Meanwhile, when the door arm 343 moves to the preset door opening position DP1, the door opening and closing sensor 560 can sense this and transmit a signal thereto to the control unit 510. Therefore, when it is determined that the door 341 is opened, the control unit 510 controls to stop driving the door motor 342.

[0429] The dust collection method of the cleaning machine workstation 300 may further include a dust collecting step ( S500 ).

[0430] This step ( S500 ) is performed after the interior of the housing 310 and the interior of the dust container body 221 are connected to each other, and is a step of driving the dust collecting motor 391 to collect dust into the capturing portion 370 .

[0431] In this step (S500), when the preset dust collection waiting time tw has passed, the control unit 510 causes the dust collection motor 391 to operate. Here, the discharge cover and the door 341 need to be opened during the dust collection waiting time tw. For example, when more than 6 seconds and less than 7 seconds have passed after the dust can 220 is fixed, the control unit 510 controls to drive the dust collection motor 391. For example, when more than 10 seconds and less than 11 seconds have passed after the dust can 220 is coupled to the coupling portion 320, the control unit 510 controls to drive the dust collection motor 391.

[0432] The control unit 510 gradually increases the rotation speed of the dust collecting motor 391 to the preset dust collecting speed Ws during the preset suction increase time tsi. For example, the control unit 510 gradually increases the rotation speed of the dust collecting motor 391 to the above-mentioned dust collecting speed Ws during a period of more than 3 seconds and less than 5 seconds. Thus, the dust collecting motor 391 is protected and the life of the dust collecting motor 391 is extended.

[0433] In this step, the control unit 510 rotates the dust collecting motor 391 at the above-mentioned dust collecting speed Ws during the preset dust collecting time ts2. For example, in the dust collecting step, the control unit 510 rotates the dust collecting motor 391 at the above-mentioned dust collecting speed Ws for a period of time of more than 14 seconds and less than 16 seconds, but is not limited thereto, and the dust collecting time ts1 may be changed to be set according to the output of the dust collecting motor 391 and the amount of dust stored in the dust barrel 220.

[0434] In this step, the dust inside the dust canister 220 is collected in the capture portion 370 through the dust canister, the hole 321a, and the flow path portion 380. Therefore, the user can remove the dust inside the dust canister 220 without additional operation, thereby improving the convenience of the user.

[0435] In addition, after the dust collection step (S500), additional dust collection can be performed on the dust and hair remaining in the joint 320. The control unit 510 locks the door 341 and rotates the dust collection motor 391 at a speed lower than the dust collection speed Ws for a preset additional dust collection time ts2 to perform the additional dust collection. This has the effect of concentrating negative pressure on the bypass hole 322c to remove the remaining dust that could not be removed in the dust collection step (S500).

[0436] After the dust collecting step (S500) is completed or after the additional dust collection is completed, the control unit 510 controls the dust collecting motor 391 to stop.

[0437] At this time, the control unit 510 gradually reduces the rotation speed of the dust collecting motor 391 during the preset suction reduction time tsd. Thereby, the dust collecting motor 391 is protected and the life of the dust collecting motor 391 is extended.

[0438] The dust collection method of the cleaning machine workstation 300 may further include a compression step ( S600 ).

[0439] This step ( S600 ) is a step of compressing the collected dust by the rotation of the compression unit 410 disposed inside the capture unit 370 .

[0440] In this step (S600), the control unit 510 controls the compression motor 420 to rotate forward or reversely, thereby the compression unit 410 rotates forward or reversely to compress the dust. Here, based on the state of the cleaning machine workstation 300 viewed from above, the forward direction of the compression motor 420 and the compression unit 410 is defined as the clockwise direction CW, and the reverse direction is defined as the counterclockwise direction CCW.

[0441] In the above reference Fig.12 In the illustrated embodiment, when the compression motor 420 rotates in the forward direction, the compression portion 410 rotates in the reverse direction, and when the compression motor 420 rotates in the reverse direction, the compression portion 410 rotates in the forward direction.

[0442] The compressing step ( S600 ) may include an initial compressing step ( S610 ) of performing a rotational motion of the compressing part 410 before the dust collecting step ( S500 ).

[0443] More specifically, in the initial compression step (S610), the rotating plate 413 included in the compression part 410 rotates forward or reverse once to compress the collected dust. In the initial compression step (S610), the control part 510 controls the compression motor 420 to rotate and drive forward or reverse only once, and then stops the compression motor 420. That is, the compression motor 420 rotates and drives for the initial compression time tp1, which is not a preset time and changes according to the amount of dust stored inside the capture part 370.

[0444] For example, when a small amount of dust is accumulated in the capturing portion 370 , the initial compression time tp1 becomes longer, and the larger the amount of dust accumulated in the capturing portion 370 , the shorter the initial compression time tp1 becomes.

[0445] In addition, the initial compression step (S610) may be performed while the control unit 510 senses that the dust cylinder 220 of the cleaning machine 200 is coupled to the coupling unit 32. That is, the initial compression step (S610) may be performed during the execution of at least one of the fixing step (S200), the cover opening step (S300), and the door opening step (S400). The initial compression step (S610) may be completed before the start time point of the dust collection step (S500).

[0446] If the volume of the compressed dust is expanded again for some reason (for example, if vibration is applied to the cleaning machine workstation and the compressed dust is scattered inside the capture part), there is a problem that the space available for storing the dust in the next dust collection step becomes narrower. However, if the initial compression step (S610) is performed, even in such a case, a wider storage space for the dust captured in the dust collection step (S500) can be ensured.

[0447] In addition, the initial compression step (S600) is not performed before the other steps (S200, S300, S400) performed before the dust collection step (S500), but is performed simultaneously with any one or more of the above-mentioned other steps, so it has the advantage of preventing the entire operating time of dust emptying from being excessively increased.

[0448] The compressing step ( S600 ) may include a main compressing step ( S620 ) of performing a rotation action of the compressing part 410 after the dust collecting step ( S500 ).

[0449] More specifically, in the main compression step (S620), the rotating plate 413 of the compression unit 410 repeatedly performs a rotation cycle including forward rotation and reverse rotation multiple times, thereby compressing the collected dust. In the main compression step (S620), after the compression motor 420 rotates in one direction, when the force applied to the compression motor 420 as the dust is compressed becomes greater than a set value, the rotation direction is changed to another direction. That is, in the main compression step (S620), the compression unit 410 (specifically, the rotating plate 413 of the compression unit 410) repeatedly and alternately rotates forward and reverse.

[0450] In an optional embodiment, the main compression step (S620) and the additional dust collection described above are performed simultaneously. Because the amount of dust captured in the additional dust collection step is very small, the additional dust collection and the main compression step (S620) can be performed simultaneously, in which case there is an advantage that the entire operating time can be prevented from being excessively increased.

[0451] The compression unit 410 is rotated in the main compression step (S620) during the preset compression time tp2. Here, regardless of the amount of dust collected, the compression time tp2 is set to rotate the rotating plate 413 for more than the preset minimum number of compressions. For example, the minimum number of compressions may be more than 5 times, and the compression time tp2 may be more than 40 seconds. The minimum number of compressions and the compression time may be appropriately changed in design.

[0452] In this way, the minimum reference for the compression time and the number of compressions is set in advance, so that the dust inside the capture part 370 can be effectively compressed. At the same time, although the compression time is fixed, the amount of dust stored gradually increases, so the more the amount of dust collected, the more the number of rotation cycles of the compression part 410 increases. That is, the more the amount of dust collected, the more times it is compressed, so there is an effect of more effectively compressing the dust inside the capture part 370.

[0453] When the compression time has elapsed, the control unit 510 controls the compression motor 420 to stop and not drive it any more.

[0454] The compression unit 410 stops after repeating a rotation cycle including forward rotation and reverse rotation for a plurality of times. In this way, when the compression unit 410 rotates in a cycle unit, after the compression step is completed, the rotating plate 413 is configured at a second position in the opposite direction to the first position where the rotation was started in the initial compression step (S610).

[0455] More specifically, refer to Fig.23 In the illustrated embodiment, the rotating plate 413 that starts rotating at the first position (left) in the initial compression step (S610) is disposed at the second position (right) after completing a plurality of rotation cycles in the main compression step (S620).

[0456] If the rotation is not a periodic unit but an individual rotation, the dust may accumulate to the left or right side with respect to the fixed plate 412, and the compressed dust may block the flow path. However, as described above, in the embodiment of the present invention, the dust is evenly accumulated to the left and right sides with respect to the fixed plate 412, so there is an advantage of preventing such a problem.

[0457] The dust collection method of the cleaning machine workstation 300 may further include a door and cover locking step ( S700 ).

[0458] This step (S700) is a step performed after the dust collection process is completed, and is a step in which the door 341 locks the dust cylinder and the hole 321a through the driving of the door motor 342.

[0459] In this step, the control unit 510 controls the door motor 342 to rotate in the reverse direction, so that the door 341 locks the dust canister and the hole 321a. More specifically, when the preset suction end time tse has passed after the driving of the dust collecting motor 391 ends, the control unit 510 controls the door motor 342 to rotate in the reverse direction, thereby locking the dust canister and the hole 321a through the door 341.

[0460] In the embodiment of performing additional dust collection, the dust cylinder and the hole 321a are already locked by the door 341, so the control unit 510 rotates the door 341 forward and then reverses it. That is, the door 341 is controlled to reopen the dust cylinder and the hole 321a and then lock them.

[0461] In this way, the reason why the locked dust canister and hole 321a are reopened and then locked is that when additional dust collection is performed, negative pressure is applied to the door 341, which may cause the dust canister and hole 321a to be opened to a small extent. Therefore, the dust canister and hole 321a are reliably locked by opening and locking the dust canister and hole 321a again.

[0462] In addition, when the control unit 510 controls the door motor 342 to rotate in the reverse direction, the door 341 pushes the discharge cover 222 to the outside of the housing 310, and the discharge cover 222 can be reconnected to the dust canister body 221 when the door 341 locks the dust canister and the hole 321a.

[0463] The dust collecting method of the cleaning machine workstation 300 may further include a fixing release step ( S800 ).

[0464] This step ( S800 ) is a step performed after the door 341 closes the dust canister and the hole 321 a , and is a step of releasing the dust canister 220 fixed to the coupling portion 320 by driving the fixing portion motor 580 .

[0465] More specifically, in this step, when the control unit 510 receives a signal from the door opening and closing sensor 560 that the door 341 locks the dust canister and the hole 321a, it controls the fixing unit motor 580 to rotate in the reverse direction, thereby releasing the dust canister 220 from being fixed.

[0466] In an optional embodiment, the control unit 510 controls the fixing unit motor 580 to drive for a preset fixing release time tf. For example, the control unit 510 controls the fixing unit motor 580 to drive in reverse for a time period of more than 4 seconds and less than 5 seconds.

[0467] When the fixing release step (S800) is performed, the user may separate the cleaning machine 200 from the housing 310 or separate the dust canister 220 from the housing 310. The user may perform cleaning using the cleaning machine 200 with the dust removed from the dust canister 220.

[0468] In addition, in the embodiment of the present invention, the cleaning machine system 3 includes the cleaning machine 200 and the cleaning machine workstation 300 and may also include a display device.

[0469] The display device displays notifications in a preset plurality of steps according to the dust collection amount calculated by the rotation angle sensed by the compression state sensing part 440 .

[0470] In an optional embodiment, the display device may be a device that visually displays driving information related to the operation of the cleaning machine workstation 300. As an example, the display device may be the display unit 530 of the cleaning machine workstation 300 described above.

[0471] Meanwhile, the driving information related to the operation of the cleaning machine workstation 300 may include information of the currently executed operation (collecting dust, charging, compressing, etc.) in addition to the notification issued according to the dust collection amount.

[0472] Alternatively, in an optional embodiment, the display device may be a device that visually displays driving information related to the operation of the cleaning machine 200. As an example, the display device may be the operating unit 218 of the cleaning machine 200 described above. In this embodiment, information about the amount of dust collection is transmitted from the cleaning machine workstation 300 to the cleaning machine 200 via wired or wireless communication.

[0473] Meanwhile, the driving information related to the operation of the cleaning machine 200 may include information related to the attractiveness of the cleaning machine, information related to the remaining battery level of the cleaning machine, etc., in addition to the notification issued according to the dust collection amount.

[0474] Alternatively, in an optional embodiment, the display device may be a portable terminal 600. In this case, the display device is an easily portable wireless communication electronic device, such as an external portable phone, a PDA, a notebook computer, a digital camera, a game console, an electronic book, etc. In this embodiment, information on the amount of dust collection is transmitted from the cleaning machine workstation 300 to the terminal 600 via wireless communication.

[0475] In addition, the display device is not limited to any of the above embodiments, and may be included in more than two components. That is, the dust collection amount may be selectively displayed on any one of the cleaning machine 200, the cleaning machine workstation 300, and the terminal 600, or may be displayed on at least two or all components.

[0476] As described above, according to the present invention, the compression part compresses the dust while moving in the internal space of the capturing part, thereby having an effect of improving the storage efficiency of the dust captured in the capturing part.

[0477] Furthermore, according to the present invention, the amount of dust captured in the capturing portion is displayed on the display portion, so there is an advantage that the user can easily check the amount of dust captured in the capturing portion without taking out the capturing portion for checking.

[0478] In addition, according to the present invention, the collected amount of dust compressed and stored inside the capture part is displayed on the display part as a warning notification through multiple levels, thereby having the following advantage: the user can choose the appropriate time he or she wants to remove the dust before the capture part is full of dust.

[0479] In addition, according to the present invention, the amount of dust collected in the capturing portion is calculated by the rotation angle of the compression portion, and the above-mentioned rotation angle is calculated based on the number of changes in the pattern formed on the driving gear. Therefore, it has the following advantages: even if the rotation speed of the compression portion changes due to the entrapment of foreign matter, the amount of dust can be accurately calculated.

[0480] The effects of the present invention are not limited to the effects mentioned above, and those skilled in the art can clearly understand other effects not mentioned here based on the description of the claims.
