The cleaner system includes a first station coupled with a first cleaner, and a second station docked with a second cleaner, thus allowing dust to be collected from both a dust bin of the first cleaner and a dust bin of the second cleaner. Further, it is possible to selectively switch a suction path between a first suction path for sucking dust from the dust bin of the first cleaner and a second suction path for sucking dust from the dust bin of the second cleaner according to the opened or closed state of a door without the necessity of adding components for switching the path.

Description

Sweeper system

The present invention relates to a sweeper system arranged to remove dust from a dust bin of the sweeper. More specifically, the present invention relates to a sweeper system that is capable of selectively switching between an internal path for sucking dust from a dust bin of a first sweeper and an inner path for sucking dust from a dust bin of a second sweeper. Switch the suction path between external paths.

Generally speaking, a sweeper is a household appliance that uses electricity to suck in air to collect small debris or dust and fill it into a dust bin contained therein, and is often referred to as a vacuum cleaner.

Such sweepers can be divided into manual sweepers and automatic sweepers, where manual sweepers are moved by users for cleaning, while automatic vacuum cleaners can be driven automatically for cleaning. Manual vacuum cleaners can be divided into canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners according to the shape of the sweeper.

In the past, canister vacuum cleaners were widely used as household sweepers. But recently, more and more people are using handheld vacuum cleaners and stick vacuum cleaners because the dust box and the sweeper body are integrated into one to increase the convenience of use.

The canister vacuum cleaner is configured such that the body and the suction inlet are connected together via a rubber hose or tube, and if necessary, the brush can be inserted into the suction inlet.

Handheld vacuum cleaners are designed to maximize portability and are lightweight but short in length, so handheld vacuum cleaners should be used while seated, so the cleaning area may be limited. Therefore, handheld vacuum cleaners are used for cleaning local areas, such as tabletops, sofas, or car interiors.

Stick vacuum cleaners can be used while standing, so the user does not have to bend forward to clean. Therefore, it is advantageous to move across a larger area while cleaning. Handheld vacuum cleaners can clean tight spaces, while stick vacuum cleaners can clean wider spaces or high places that are out of reach. Recently, stick vacuum cleaners can be set to a modular type and actively change their type based on different goals.

Moreover, recently, cleaning robots that can perform cleaning operations without user control are also widely used. The cleaning robot automatically cleans the target area by absorbing foreign matter such as dust from the floor and driving automatically on the area to be cleaned.

However, a problem with conventional stick vacuum cleaners and conventional cleaning robots is that each has a small-capacity dust box for storing collected dust, making it inconvenient for users to empty the dust box after each use.

In this regard, Korean Patent Application Publication No. 10-2020-0074001, which is an invention for processing dust collected in a stick vacuum cleaner, has been proposed as a patent document.

The patent document No. 10-2020-0074001 discloses a cleaning device, including: a vacuum cleaner having a dust collector capable of collecting foreign objects; and a docking station connected to the dust collector to remove foreign objects collected in the dust collector . Furthermore, the cleaning device is provided with a dust collector docked on the docking station, and the docking station is configured to include a suction device for sucking foreign matter and internal air in the dust collector docked on the docking station. Furthermore, the cleaning device is configured to include a collection member that collects foreign matter in the docking station.

Meanwhile, US Patent No. 10463215 has been proposed as a patent document, which is an invention for processing dust collected by a cleaning robot.

US Patent No. 10463215 discloses a discharge station, which includes a base that accommodates a cleaning robot and is docked with the cleaning robot accommodated in the base. Furthermore, the discharge station includes a canister and an air mover, wherein the canister accommodates the filter bag and the air mover moves air to the filter bag to collect dust from the cleaning robot.

However, this patent document is configured to collect dust only from the dust bin of a stick vacuum cleaner or cleaning robot. That is, the invention disclosed in the above-mentioned patent document is a cleaning device (or discharge station) dedicated to one type of cleaning machine, and the problem is that it cannot collect from both the dust box of the stick vacuum cleaner and the dust box of the cleaning robot Dust.

At the same time, although stick vacuum cleaners and cleaning robots have improved user convenience, due to structural shape restrictions and technical problems, it is difficult to clean perfectly with just one vacuum cleaner. Therefore, users purchase and use both stick vacuum cleaners and cleaning robots. Or, after the user purchases one type of cleaning machine, he also purchases another type of cleaning machine.

Therefore, there is a need to develop a system capable of collecting dust from both the dust box of a stick vacuum cleaner and the dust box of a cleaning robot.

In addition, in order to avoid the problem of reduced suction power when implementing the function of collecting dust from the dust boxes of two types of sweepers in one system, it is necessary to develop a structure that can switch paths between a stick vacuum cleaner and a cleaning robot, in which , one suction path is used to suck and collect dust from the dust box of the stick vacuum cleaner, while the other suction path sucks and collects dust from the dust box of the cleaning robot.

In addition, since users usually purchase and use a stick vacuum cleaner first and then purchase a cleaning robot, it is necessary to develop a structure based on a docking station dedicated to the stick vacuum cleaner that can be substantially coupled to a docking station dedicated to the cleaning robot.

FIG. 1 is a perspective view of a cleaning machine system according to an embodiment of the present invention; and FIG. 2 is a side cross-sectional view showing the cleaning machine of FIG. 1 .

Referring to FIGS. 1 and 2 , a cleaning machine system 1 according to an embodiment of the present invention may include: a first docking station 10 ; a second docking station 20 ; and an external path 30 .

The first docking station 10 may be coupled with the first sweeper 50 to suck dust from inside the dust box 516 of the first sweeper 50 . Accordingly, the first docking station 10 may include a housing 110 defining an interior space for housing a plurality of components.

Moreover, the first docking station 10 can be used as a charging station, which charges the first cleaning machine 50 by supplying power to the first cleaning machine 50 when the first cleaning machine 50 is coupled to the first docking station 10 .

The first cleaning machine 50 may be coupled to the front of the first docking station 10 . More specifically, the sweeper body 510 of the first sweeper 50 may be coupled to the front of the first docking station 10 .

In this regard, the term "front" may be defined as the direction facing the coupler 115 formed by pressing the housing 110, which will be described later and whose shape corresponds to the first sweeper 50 of the cleaning machine body 510. The direction facing the opposite surface of the housing 110 relative to the coupler 115 may be defined as rearward. Furthermore, the direction in which the main axis A1 of the housing 110 is disposed may be defined as a vertical direction. In this case, the side on which the coupler 115 is disposed may be the upper part.

The second docking station 20 is operable to suck dust from inside the dust box 610 of the second sweeper 60 . Therefore, the second docking station 20 can be docked with the second cleaning machine 60 . The second docking station 20 may be disposed below the first docking station 10 and may be coupled with the first docking station 10 .

Moreover, when the second cleaning machine 60 is docked on the second docking station 20 , the second docking station 20 can serve as a charging station, which supplies power to the second cleaning machine 60 to charge the second cleaning machine 60 . The second dock 20 may dock with the second sweeper 60 in the same direction as the first sweeper 50 is coupled to the first dock 10 . Therefore, if the direction of coupling the first cleaner 50 and the direction of docking the second cleaner 60 are the same, the space occupied by the cleaner system 1 can be reduced.

At least part of the external path 30 may be provided outside the first docking station 10 . The external path 30 may communicate with the interior of the housing 110 and the dust box 610 of the second cleaner 60 . The outer path 30 may be formed in a tube shape defining a passage through which dust in the dust box 610 of the second sweeper 60 may be collected in the housing 110 .

Hereinafter, first, the structure of the first cleaning machine 50 coupled to the first docking station 10 will be briefly described, and then the structure of the first docking station 10 will be described with reference to FIGS. 3 and 4 .

FIG. 3 shows the first cleaning machine 50 coupled to the first docking station 10 ; and FIG. 4 is an enlarged view showing the opening and closing structure of the dust box 516 of the first cleaning machine 50 .

The first cleaner 50 may be a stick vacuum cleaner configured so that a user can hold the handle 514 and then manually clean the room, and may include: a cleaner body 510; an extension tube 520; and a suction nozzle 530 .

The cleaning machine body 510 of the first cleaning machine 50 may include: a suction part 511 that provides a path for air containing dust to pass; a dust separation part 512 that is connected with the suction part 511 and separates all dust through the suction part 511 dust to be sucked; a suction motor 513 that generates suction to suck air; a handle 514 for the user to hold; and a battery case 515 for housing the battery.

The cleaning machine body 510 of the first cleaning machine 50 may further include a dust box 516 .

Here, the dust box 516 may be communicated with the dust separation part 512 and may store separated dust in the dust separation part 512 .

Referring to FIG. 4 , the dust box 516 may include: a dust box body 5161 ; a discharge cover 5162 ; and a coupling rod 5163 .

The dust box body 5161 may have a cylindrical shape, and one side thereof may be open. The air introduced through the suction part 511 may pass through the dust separation part 512 accommodated in the dust box body 5161. In this case, dust may be collected in the dust box body 5161 , and air separated from the dust may flow to the suction motor 513 and then be discharged to the outside of the first cleaner 50 .

The discharge cover 5162 may be rotatably coupled to the opening side of the dust box body 5161. More specifically, the discharge cover 5162 may be coupled to the dust box body 5161 via a dust box hinge 5164 on the open side of the dust box body 5161 . In this case, the dust box hinge 5164 may be provided on a side close to the battery case 515. The discharge cover 5162 can rotate around the dust box hinge 5164 to open or close the dust box body 5161.

Furthermore, the discharge cover 5162 may include a coupling hook (not shown) located on a side close to the suction part 511 , and the coupling hook is hooked on the dust box body 5161 . The coupling hook and dust bin hinge 5164 may be provided on opposite sides.

The coupling rod 5163 may be disposed to move along the outer circumference of the dust box body 5161 and in the longitudinal direction of the dust box body 5161 to release the hook coupling between the discharge cover 5162 and the dust box body 5161 . When the first cleaning machine 50 is coupled to the first docking station 10, the coupling rod 5163 may be disposed downward. If an external force is applied to the coupling rod 5163 to move the coupling rod 5163 along the longitudinal direction of the dust box body 5161 (ie, the direction in which the release hook is coupled), the coupling hook extending from the discharge cover 5162 can be elastically deformed and the discharge can be released. The hook coupling between the cover 5162 and the dust box body 5161.

Hereinafter, the structure of the first docking station 10 will be described with reference to FIGS. 2 , 5 and 11 .

5 is a perspective view of the first docking station 10; and FIG. 6 is a view showing the arrangement relationship between the first cleaning machine 50 and the housing 110 and the arrangement structure of the outer wall surface of the housing 110.

As mentioned above, the first docking station 10 may include a housing 110 .

Referring to FIG. 5 , the housing 110 may be a component to which the first sweeper 50 is coupled and may define the appearance of the first docking station 10 . Specifically, the housing 110 may be formed in a columnar shape including an outer wall surface. For example, the housing 110 may be formed into a shape similar to a square column.

The assembly including the dust collection motor 130 , the internal path 120 and the dust collection component 140 may be accommodated in a space defined within the housing 110 .

Housing 110 may include ground support 112 . Here, the ground support 112 may be disposed toward the ground. More specifically, the ground support 112 may be provided on the lower end of the housing 110 . Furthermore, the ground support 112 may be detachably coupled to the lower end of the housing 110 . The bottom surface of the ground support 112 contacting the ground may be arranged parallel to the ground, or may be arranged to be inclined at a predetermined angle with the ground. Through this configuration, heavier components such as the dust collection motor 130 housed in the housing 110 can be stably supported, so that the overall weight can be balanced even if the first cleaner 50 is coupled to the upper portion of the housing 110 .

Moreover, the cross section of the ground support 112 may be larger than the cross section surrounded by the outer wall at the lower end of the housing 110 to increase the area in contact with the ground, thereby preventing the sweeper docking station from falling down and maintaining balance. For example, ground support 112 may be in the shape of a rectangular plate.

As mentioned above, the housing 110 may include at least one outer wall. For example, the housing 110 may include a first outer wall surface 111a on which the coupler 115 is formed, and may further include: a second outer wall surface 111b; a third outer wall surface 111c; and a fourth outer wall surface 111d. When facing the first outer wall surface 111a, the walls will be arranged counterclockwise in order (see Figure 6).

The housing 110 can be opened to expose some components contained therein (such as the dust collecting component 140). For example, when viewing the first docking station 10 from the front, the right portion of the first outer wall surface 111a and the second outer wall surface 111b can be integrally opened together in the direction of the second outer wall surface 111b, and the right portion of the first outer wall surface 111a can be opened together. The left part and the fourth outer wall surface 111d may be integrally opened together in the direction of the fourth outer wall surface 111d.

The first outer wall surface 111a may be pressed toward the inside of the housing 110, so that the coupler 115 formed on the first outer wall surface 111a corresponds in shape to a part of the cleaning machine body 510 of the first cleaning machine 50. With such configuration, a portion of the first cleaning machine 50 can be coupled to the first docking station 10 , and the first cleaning machine 50 can be supported by the first docking station 10 . In this article, a part of the first cleaner 50 may represent a certain area of the dust box 516 of the first cleaner 50 and a certain area of the battery case 515 of the first cleaner 50 .

Hereinafter, the shape of the coupler 115 will be described with reference to FIG. 7 .

FIG. 7 is an enlarged view of the coupler 115 to which the first cleaning machine 50 is coupled in the housing 110 of the first docking station 10 .

The dust box 516 and the battery case 515 of the first cleaner 50 may be coupled to the coupler 115 . Referring to FIG. 7 , coupler 115 may include coupling surface 1151 . The coupling surface 1151 may be disposed parallel to the outer wall surface of the housing 110 . For example, the coupling surface 1151 may be referred to as a surface formed in a groove shape from the first outer wall surface 111 a toward the inside of the housing 110 . In other words, the coupling surface 1151 may be called a surface that forms a step with the first outer wall surface 111a.

The coupling surface 1151 may contact the bottom surface of the dust box 516 and the battery case 515 of the first cleaning machine 50 . Herein, when the user uses the first cleaning machine 50 or places the first cleaning machine 50 on the ground, the bottom surface of the dust box 516 may be referred to as the surface facing the ground.

A dust through hole 1151a may be formed on the coupling surface 1151 to allow air existing outside the housing 110 to flow into the coupling surface 1151. The shape of the dust through hole 1151a may be formed to correspond to the shape of the dust box 516 to allow dust present in the dust box 516 to flow into the dust collecting part 140. Specifically, the dust through hole 1151a may be formed to correspond to the shape of the discharge cover 5162 to allow the discharge cover 5162 to pass therethrough when the discharge cover 5162 of the dust box 516 is opened. The dust through hole 1151a may be formed to communicate with the internal path 120.

Coupler 115 may include a dust bin guide surface 1152 . The dust box guide surface 1152 may be provided on the first outer wall surface 111a. The dust box guide surface 1152 may be connected to the first outer wall surface 111a. Furthermore, the dust box guide surface 1152 may be connected to the coupling surface 1151.

The dust box guide surface 1152 may be shaped to correspond to the outer surface of the dust box. Therefore, convenience may be provided when the first cleaner 50 is coupled to the coupling surface 1151 . When the first cleaning machine 50 is coupled to the first docking station 10 , the dust box can be supported through the dust box guide surface 1152 .

Coupler 115 may include guide tabs 1153 . The guide protrusion 1153 may be provided on the coupling surface 1151. The guide protrusion 1153 may be formed to protrude from the coupling surface 1151 . The two guide protrusions 1153 may be provided spaced apart from each other. The distance between the two guide protrusions 1153 spaced apart from each other may correspond to the width of the battery case 515 of the first cleaner 50 . Therefore, convenience may be provided when the first cleaner 50 is coupled to the coupling surface 1151 .

Coupler 115 may include coupler sidewalls 1155 . The coupler side walls 1155 may represent walls provided on both sides of the coupling surface 1151 and may be vertically connected to the coupling surface 1151 . Coupler sidewall 1155 may be connected to first outer wall surface 111a. Furthermore, the coupler sidewall 1155 may be connected to the dust box guide surface 1152. In other words, the coupler sidewall 1155 may form a surface connected to the dust bin guide surface 1152 . Therefore, the first cleaning machine 50 can be prevented from shaking left and right, and the first docking station 10 can stably accommodate the first cleaning machine 50 .

Coupler 115 may include a coupling sensor (not shown). The coupling sensor can detect whether the first cleaning machine 50 is coupled to the coupler 115 .

Coupling sensors may include contact sensors. For example, coupling sensors may include microswitches. In this case, the coupling sensor may be provided on the guide protrusion 1153 . Therefore, if the battery case 515 of the first cleaner 50 is coupled between the pair of guide protrusions 1153 , the coupling sensor can sense the first cleaner 50 by contacting the battery case 515 .

Coupling sensors may include contactless sensors. For example, coupling sensors may include IR sensors. In this case, the coupling sensor may be disposed on the coupling side wall 1155 and may be opposite to the dust box 516 or the battery case 515 of the first sweeper 50 .

The coupling sensor can sense the first cleaning machine, and can further sense whether there is a battery powering the first cleaning machine 50 , and thus finally determine whether the first cleaning machine 50 is coupled to the coupler 115 .

At this time, if the battery is electrically coupled to the first cleaning machine charging terminal 1156, it can be determined that power is supplied to the battery. The first cleaner charging terminal 1156 may be provided on the coupling surface 1151 . If the first cleaner charging terminal 1156 is coupled to the battery, power may be supplied to the first cleaner 50 .

The coupler 115 may further include a securing member contact hole 1157 . The securing member contact hole 1157 may be formed in the shape of an elongated hole along the coupler side wall 1155 to allow entry and exit of the securing member 161, which will be described below. For example, the securing member contact hole 1157 may be a rectangular hole formed along the coupler sidewall 1155 . The fixing member 161 will be described in detail together with the fixing unit 160 below.

The first stop 10 may include an internal path 120 .

Referring to FIG. 2 , if the door 151 , which will be described below, is opened, the internal path 120 may be accommodated in the housing 110 and may communicate with the dust box 516 of the first sweeper 50 . Internal path 120 may be disposed vertically in housing 110 . The internal path 120 may be arranged generally parallel to the main axis A1 of the housing 110 . The internal path 120 may be configured in the shape of a tube defining a space therein to form a passage for dust to pass. The internal path 120 may be formed such that a cross section of the first side thereof coupled to the dust through hole 1151 a is larger than a cross section of the second side thereof coupled to the dust collecting member 140 . In other words, the inner path 120 may be provided in a tubular shape, the cross-sectional area of which decreases in the direction from an upper position to a lower position.

The first docking station 10 may include a dust collection motor 130 .

Referring to FIG. 2 , the dust collection motor 130 may be accommodated in the housing 110 and may generate suction force to suck dust from the dust box 516 of the first cleaner 50 and the dust box 610 of the second cleaner 60 . The dust collection motor 130 may be located in a lower position in the housing 110 . Therefore, air can flow from an upper position to a lower position in the housing 110 .

The first docking station 10 may include a dust collection component 140 .

Referring to FIG. 2 , the dust collecting component 140 may be accommodated in the housing 110 and may be disposed above the dust collecting motor 130 . Since the dust collecting component 140 is disposed above the dust collecting motor 130, if the dust collecting motor 130 generates suction force, the dust sucked from the dust box 516 of the first cleaning machine 50 and the dust box 610 of the second cleaning machine 60 can be collected in the dust collector. Dust component 140.

The dust collecting part 140 may collect dust through the first suction path, the internal path 120 and the dust collecting part 140 connected to the dust box 516 of the first sweeper 50 . Furthermore, the dust collecting part 140 may collect dust through the second suction path, the outer path 30 , the inner path 120 and the dust collecting part 140 connected to the dust box 610 of the second cleaner 60 .

The dust collection part 140 may be detachably coupled to the housing 110 . Therefore, if the housing is opened, the dust collection component 140 can be separated from the housing 110 for disposal, and then a new dust collection component 140 can be coupled to the housing 110 . In other words, the dust collection component 140 may be defined as a consumable component.

If the suction force is generated by the dust collecting motor 130, the capacity of the dust collecting part 140 can be increased to collect the dust in the dust collecting part 140. Therefore, the dust collecting part 140 can be made of breathable material that cannot allow foreign matter such as dust to pass through. For example, the dust collection member 140 may be made of non-woven material and become hexagonal as its capacity increases.

Meanwhile, the first end of the internal path may be coupled to the dust through hole 1151a, and the second end of the internal path 120 may be coupled to the dust collecting component 140. Therefore, if the dust collection motor 130 is driven to generate suction, the air flow may be formed from the first end to the second end of the internal path 120 . The air containing foreign matter flowing out from the inside of the dust box 516 of the first cleaner 50 can flow through the internal path 120 to the dust collecting component 140 and then escape from the dust collecting component 140 while leaving only the foreign matter in the dust collecting component 140 .

The first docking station 10 may include a fixing unit 160 .

FIG. 8 is a view showing a state in which the fixing unit 160 of the first docking station 10 is coupled to the coupler 115 .

Referring to FIG. 8 , a portion of the fixing unit 160 may be provided on the coupler side wall 1155 . Furthermore, a part of the fixing unit 160 may be disposed behind the coupling surface 1151 to be accommodated in the housing 110 .

The fixing unit 160 may fix the first cleaner 50 coupled to the coupling surface 1151 . More specifically, the fixing unit 160 may fix the battery case 515 and the dust box 516 of the first cleaner 50 coupled to the coupling surface 1151 .

The fixing unit 160 may include: a fixing member 161; a fixer motor 162; and a fixing seal 163.

The retaining member 161 may receive power from the retainer motor 162 to move back and forth from within the coupler sidewall 1155 of the coupler 115 toward the dust bin. The fixing member 161 can enter and exit the side wall through the fixing member contact hole 1157 of the fixing member 161 . The shape of the upper part of the fixing member 161 may be formed to correspond to the shape of the battery case 515 , and the shape of the lower part of the fixing member 161 may be formed to correspond to the shape of the dust box body 5161 .

This type of configuration can prevent a gap from appearing between the dust box 516 and the fixing member 161 or between the battery case 515 and the fixing member 161 when the fixing member 161 is rotated to surround the dust box 516 and the battery case 515, and can When dust is sucked by the dust collection motor 130 , the dust in the dust box 516 is prevented from being scattered outside the first docking station 10 .

The retainer motor 162 may be powered to move the retaining member 161 . Specifically, the fixing member 161 can move in a direction to press the dust box 516 from the inside of the coupling side wall 1155 through the fixer motor 162, thereby fixing the first sweeper 50 to the first docking station 10, or it can be moved from the fixing member 161 to the first docking station 10. 161 presses the position of the dust box 516 to move inside the coupling side wall 1155, thereby releasing the first sweeper 50 from the first docking station.

When coupled to the first sweeper 50, a fixed seal 163 may be provided on the dust box guide surface 1152 to airtightly seal the dust box 516. When the dust box 516 of the first cleaning machine 50 is coupled, this configuration can press and fix the seal 163 through the weight of the first cleaning machine 50, and can seal the dust box 516 and the dust box guide surface 1152 to prevent airflow leakage. .

The first docking station 10 may include a door unit 150 .

9 is an enlarged view of the door unit 150 of the first docking station 10; and FIG. 10 is a view showing the arrangement relationship in a state where both the discharge cover 5162 and the door 151 of the first cleaner 50 are opened.

Referring to FIG. 9 , the door unit 150 may be disposed across the coupler 115 and the rear of the coupler 115 , and may include: a door 151 ; a door arm 152 ; and a door motor unit 153 .

Door 151 may be provided on coupler 115 and may be configured to communicate the exterior of housing 110 with interior path 120 . More specifically, the door 151 may be coupled with the door hinge 154 in the housing 110 and may rotate about the door hinge 154 to move toward the interior of the upper portion of the housing 110 to open and close the interior and exterior of the housing 110 . More specifically, the door hinge 154 may be provided on an upper end of the dust through hole 1151a on a side opposite to the coupling surface 1151, and the door 151 may be coupled to the door hinge 154 to be in a position to close the dust through hole 1151a .

Referring to FIG. 10 , the open state of the door 151 may indicate that the door 151 rotates around the door hinge 154 toward the inside of the housing 110 (in the first direction R1 ), so that the outside of the housing 110 communicates with the internal path 120 through the dust through hole 1151 a . In the open state of the door 151 , the door 151 may be disposed relative to the dust collection motor 130 . At this time, the door 151 may be substantially perpendicular to the main axis A1 of the housing 110 .

Furthermore, the door-closed state may represent a state in which the door 151 rotates around the door hinge 154 in the direction R2 (second direction) relative to the first direction to close the dust through hole 1151a, so that the outside of the housing 110 does not interfere with the internal path. 120 connected. In the closed state of the door 151 , since the door 151 is positioned to block the dust through hole 1151 a , the door 151 may be disposed parallel to the main axis A1 of the housing 110 .

The shape of the door 151 may be formed to correspond to the shape of the dust through hole 1151a to block the dust through hole 1151a, thereby opening and closing the inside and outside of the housing 110. For example, the door 151 may be formed in a circular shape.

The door 151 may be composed of a first door 151a and a second door 151b. At this time, the first door 151a and the second door 151b may be combined to form an entire circle, and the first door 151a and the second door 151b may be rotatably coupled at the position of the reference line. The doors 151b are separated along this reference line. For example, the first door 151a and the second door 151b may be hinged at the position of the reference line. Also, when the door 151 is closed, the first door 151a may be disposed above the dust through hole 1151a, and the second door 151b may be disposed below the dust through hole 1151a. Furthermore, the reference line may be formed such that the area of the first door 151a is larger than the area of the second door 151b.

The door arm 152 may connect the door 151 and the door motor unit 153, and may open and close the door 151 using power generated in the door motor unit 153.

For example, the door arm 152 may include: a first door arm 152a; and a second door arm 152b. A first end of the first door arm 152a may be coupled to the door motor unit 153. The first door arm 152a can be rotated by power transmitted from the door motor unit 153. The second end of the first door arm 152a may be rotatably coupled to the second door arm 152b. The first door arm 152a may transmit force from the door motor 153a to the second door arm 152b. A first end of the second door arm 152b may be coupled to the first door arm 152a. The second end of the second door arm 152b may be coupled to the door 151 . The second door arm 152b can push or pull the door 151.

If the door arm 152 pulls the door 151 when the door 151 is closed, the door 151 rotates in the first direction R1 toward the inside of the housing 110 of the first docking station 10 . At the same time, if the door arm 152 pushes the door 151 when the door 151 is open, the door 151 can rotate in the second direction R2 toward the outside of the housing 110 of the first docking station 10 .

The second door arm 152b may be coupled to the hinge at a location coupling the first door 151a and the second door 151b. If the second door arm 152b pulls the door 151 in a closed state, the first door 151a and the second door 151b can rotate around the door hinge 154 along the first direction R1 from the dust through hole 1151a.

At the same time, when the door 151 is opened to the maximum, the second door 151b may contact the inner path 120 on the first side of the inner surface of the inner path 120 (see FIG. 14). In other words, when the door 151 is opened to the maximum, the door 151 may bend relative to the hinge at coupling the first door 151a and the second door 151b. At this time, the first door 151a may be disposed substantially perpendicular to the main axis A1 of the housing 110, and the second door 151b may be disposed substantially parallel to the main axis A1 of the housing 110, and the first door 151a and the second door 151b may be together Arranged in an "L" shape. At this time, the first door 151a may be disposed relative to the dust collection motor 130.

The door motor unit 153 may provide power for rotating the door 151 to the door arm 152 . Specifically, the door motor unit 153 may rotate the door arm 152 forward or backward. In this case, the term "forward" may refer to the first direction R1 in which the door arm 152 pulls the door 151 toward the interior of the housing 110 . Furthermore, the term "backwards" may refer to the second direction R2 in which the door arm 152 pushes the door 151 toward the outside of the housing 110 .

The door motor unit 153 may include: a door arm 152; and at least one mechanism component for transmitting power to the door 151. For example, the door motor unit 153 may include: a door motor 153a; a snail gear 153b coupled to a shaft of the door motor 153a to receive power; and a worm gear 153c meshed with the snail gear 153b to receive rotational force and Change the direction of rotation. Herein, first door arm 152a may be rotatably coupled to worm gear 153c. In another example, the door motor unit 153 may include only the door motor 153a to directly transmit power from the shaft of the door motor 153a to the first door arm 152a.

The first docking station 10 may include a lid opening unit 170 .

FIG. 11 is an enlarged view of the lid opening unit 170 of the cleaning machine docking station.

Referring to FIGS. 2 and 11 , the cover opening unit 170 may be disposed below the coupler 115 in the housing 110 and may be disposed to open the discharge cover 5162 of the first cleaner 50 . The cap opening unit 170 may include: a pushing protrusion 171; a cap opening gear 172; and a cap opening motor (not shown).

When the first cleaner 50 is coupled to the coupler 115 , the pushing protrusion 171 may be in a position where the coupling rod 5163 can be pressed. The pushing protrusion 171 can move linearly back and forth to press the coupling rod 5163. Specifically, the pushing protrusion 171 may be provided on the dust box guide surface 1152. A protrusion movement hole may be formed on the dust box guide surface 1152, and the pushing protrusion 171 may be exposed to the outside through the protrusion movement hole. The pushing protrusion 171 may be coupled to the cap opening gear 172 to move along the cap opening gear 172 .

The lid opening motor can provide power for moving the pushing protrusion 171 to the lid opening gear 172 .

The lid opening gear 172 may be coupled with the lid opening motor, and may move the pushing protrusion 171 using the power of the lid opening motor. More specifically, the cap opening gear 172 may include: a first cap opening gear 172a that receives a rotational force from a shaft of the cap opening motor; and a second cap opening gear 172b that meshes with the first cap opening gear 172a and will The linear back and forth movement is transmitted to the push protrusion 171 .

In this regard, the first decapping gear 172a may be a pinion gear, and the second decapping gear 172b may be a rack.

In other words, when the cleaner body 510 of the first cleaner 50 is fixed to the coupler 115 , the cover opening motor can move the pushing protrusion 171 through the cover opening gear 172 to separate the discharge cover 5162 from the dust box body 5161 .

Next, the coupling shape of the first docking station 10 and the first cleaning machine 50 will be geometrically described.

Returning to FIG. 2 , as described above, the first cleaning machine 50 may be coupled to the front of the housing 110 . More specifically, some components of the sweeper body 510 of the first sweeper 50 may be coupled to the coupler 115 so that the entire first sweeper 50 is supported on the first docking station 10 . More specifically, if the first sweeper 50 is coupled to the coupler 115 of the housing 110, the longitudinal axis A2 of the dust box 516 of the first sweeper 50 may be disposed parallel to the ground. Furthermore, if the first cleaner 50 is coupled to the coupler 115 of the housing 110 , the longitudinal axis A2 of the dust box 516 of the first cleaner 50 may be disposed substantially perpendicular to the main axis A1 of the housing 110 . At this time, the first cleaning machine 50 can be supported such that the longitudinal axis A3 of the suction component 511 of the first cleaning machine 50 is substantially parallel to the main axis A1 of the housing 110 .

At the same time, since the first cleaning machine 50 is coupled to the first docking station 10 and the dust in the dust box 516 of the first cleaning machine 50 is collected in the dust collecting component 140 through the suction of the dust collecting motor 130, it can be used as required. This eliminates the inconvenience for users who empty the dust bin of a stick vacuum cleaner. Furthermore, dust can be prevented from flying away when the user empties the dust bin of the stick vacuum cleaner himself.

12 is a perspective view of the second docking station 20; and FIG. 13 shows that the dust box 610 of the second cleaning machine 60 and the external path 30 are connected to each other in a state where the second cleaning machine 60 is docked on the second docking station 20. method view.

Before describing the second docking station 20 , the second cleaning machine 60 docked on the second docking station 20 will be briefly described with reference to FIG. 13 . The second cleaning machine 60 may be a cleaning robot that is automatically driven to perform cleaning operations.

The second cleaning machine 60 can automatically clean the predetermined area by sucking foreign matter such as dust from the floor while moving on its own in the area to be cleaned. The second cleaning machine 60 may include: a distance sensor that detects distances from obstacles such as furniture, office supplies, or walls installed in the cleaning area; and left and right wheels for movement. The second cleaning machine 60 may be docked on or coupled to the second docking station 20 . The dust sucked into the dust box 610 of the second cleaner 60 may be collected in the dust collecting component 140 through the external path 30 .

The second cleaner 60 may include a second cleaner dust discharge hole 620 . At this time, the second cleaner dust discharge hole 620 may be provided on the lower surface of the dust box 610 of the second cleaner 60 so that the dust box 610 of the second cleaner 60 communicates with the external path 30 . For example, the second cleaner dust discharge hole 620 may be in the shape of a rectangular hole.

The second cleaner 60 may include a second cleaner discharge cover 630 . At this time, the second cleaner discharge cover 630 may be formed in a shape corresponding to the shape of the second cleaner dust discharge hole 620 , thereby closing the second cleaner dust discharge hole 620 . Therefore, the second cleaner discharge cover 630 may be provided in the second cleaner dust discharge hole 620 .

Also, a first side of the second sweeper discharge cover 630 may be fixed to the second sweeper dust discharge hole 620 to form a fixed end, and a second side thereof may form a free end. Through such a configuration, if the dust collection motor 130 generates suction, the free end can move downward while the fixed end is fixed, thereby opening the second cleaner dust discharge hole 620 . If the dust collection motor 130 stops operating, the free end of the second cleaner discharge cover 630 can move upward to close the second cleaner dust discharge hole 620 . The second sweeper discharge cover 630 may allow the dust box 610 of the second sweeper 60 and the external path 30 to communicate with each other or be closed relative to each other, depending on the direction of movement of the free end.

The second cleaning machine 60 may include corresponding terminals (not shown) for charging the battery when the second cleaning machine 60 is docked on the second docking station 20 . When the second cleaning machine 60 is docked, the corresponding terminal may be located at a position that is accessible to the second cleaning machine charging terminal 212 (see FIG. 12 ) of the second docking station 20 . For example, a pair of corresponding terminals may be provided on the bottom surface of the second cleaning machine 60 . If the corresponding terminal and the second cleaning machine charging terminal 212 are electrically connected to each other, power can be supplied from the second docking station 20 to the second cleaning machine 60 to charge the second cleaning machine.

Hereinafter, the structure of the second docking station 20 will be described with reference to FIGS. 12 and 13 .

Referring to FIGS. 12 and 13 , the second docking station 20 may include: a lower body 210 ; a side body 220 ; an upper body 230 ; and a rear body 240 .

The lower body 210 has a configuration in which the second cleaning machine 60 is attached to the second docking station 20 . The second cleaning machine 60 can climb onto the lower body 210 to be docked thereon.

The inclined part 210a may be provided on the center part of the lower body 210. The inclined part 210a may be formed by extending the upper surface 113 of the lower body 210 upward. The inclined component 210a may be formed of a plurality of inclined surfaces with different inclinations, and the inclination of each inclined surface may be set according to the appearance of the bottom surface of the second cleaning machine 60 .

The lower body 210 may include a rolling part 210b through which the left and right wheels of the second cleaning machine 60 pass when the second cleaning machine 60 moves to be docked. The rolling parts 210b may be provided on the left and right ends of the lower body 210, each end having a predetermined area in the direction of docking the second cleaner 60, and an uneven part may be formed on the upper surface of each rolling part 210b to prevent the left wheel from turning. And every one of the right wheels skids.

Based on the state of docking the second cleaner 60 , the lower body 210 may include a suction hole 211 formed at a position corresponding to the position where the dust box 610 of the second cleaner 60 is located. More specifically, based on the state of docking the second cleaner 60 , the suction hole 211 may be provided on the inclined part 210 a of the lower body 210 , and may be located at a position corresponding to the dust discharge hole 620 of the second cleaner. The shape of the suction hole 211 may be formed to correspond to the shape of the second cleaner dust discharge hole 620 . For example, the suction hole 211 may be in the shape of a rectangular hole.

Furthermore, the lower body 210 may include a second cleaning machine charging terminal 212 that is electrically connected to the second cleaning machine 60 and supplies power to the second cleaning machine 60 . If the cleaning machine 60 is docked, the corresponding terminal and the second cleaning machine charging terminal 212 may be electrically connected to each other, and power may be supplied from the second docking station 20 to the second cleaning machine 60 to charge the second cleaning machine 60 .

The side bodies 220 may be connected to both ends of the lower body 210 and may extend upward from the lower body 210 . The side body 220 may be provided on the left or right end of the lower body 210 to define the side appearance of the second docking station 20 .

When the second cleaning machine 60 is docked, the upper body 230 may be connected to the side body 220 , coupled to the first docking station 10 , and disposed above the upper surface of the second cleaning machine 60 to be spaced a predetermined distance from the upper surface. . The upper body 230 can be used as a cover to protect the upper part of the second cleaning machine 60 .

The rear body 240 may be connected to the lower body 210 , the side body 220 and the upper body 230 , and may be disposed in a direction relative to the first side on which the second cleaner 60 is docked. At this time, the second docking station 20 may further include a path support 250 connected to the rear body 240 .

The path support 250 may extend upward from the upper surface 113 of the housing of the upper body 230 to be spaced a predetermined distance from the upper surface 113 and may receive a portion of the external path 30 therein. Path support 250 may be provided to receive and support outer path 30 . For example, the path support 250 may be in the shape of a cylinder or a square column. As used herein, path support 250 may have any shape capable of receiving and supporting outer path 30 . Of course, the path support is not limited to any one shape.

Therefore, the second docking station 20 composed of the lower body 210 , the side body 220 , the upper body 230 and the rear body 240 may be formed in a housing that is opened only on the side docking the second sweeper 60 . Since the second docking station 20 is configured to be opened only on the side docked with the second sweeper 60, the first docking station 10 coupled to the upper part of the second docking station 20 can be stably supported in the structure.

Meanwhile, a storage space for accommodating a portion of the external path 30 may be formed in each of the lower body 210 and the rear body 240 . At this time, the storage spaces of the lower body 210 and the rear body 240 may be connected to each other.

At least a portion of the outer path 30 may be provided in the storage space to extend horizontally. At this time, the first end of the external path 30 may be coupled with the suction hole 211 in the storage space. The second end of the external path 30 may be coupled to the third outer wall surface 111c to be internally connected to the housing 110.

More specifically, the external path 30 may include: a first external path; and a second external path.

The first external path may be vertically provided in a direction in which a third outer wall surface 111c of the housing 110, which will be described below, is provided. Moreover, the upper end of the first external path may be connected to the internal extension tube 180 through the third external wall surface 111c of the housing 110. Since the inner extension tube 180 to be described below is provided on the inner path 120, the first outer path can be connected with the inner path 120.

The first end of the second external path may be connected to the lower end of the first external path and be horizontally disposed to communicate with the dust box 610 of the second sweeper 60 , and the second end of the second external path may be coupled to the second external path. The suction hole 211 of the docking station 20.

Such a configuration may form a second suction path in which dust is sucked in and moved to the dust box 610 of the second cleaner 60 , the outer path 30 , the inner path 120 and the dust collection component 140 .

In this way, the sweeper system 1 including the first docking station 10 , the second docking station 20 and the external path 30 can collect dust from both the dust box 516 of the first sweeper 50 and the dust box 610 of the second sweeper 60 , so the user does not need to personally remove dust from the dust box 516 and the dust box 610, thereby maximizing convenience.

Hereinafter, the path switching structure between the dust suction path through the inner path 120 and the dust suction path through the outer path 30 in the cleaner system 1 according to an embodiment of the present invention will be described with reference to FIGS. 14 to 16 .

14 is a view showing the arrangement relationship between the inner extension tube 180 and the door 151 in a state where the door is opened; and FIGS. 15 and 16 are views showing the arrangement relationship between the inner path 120 and the outer path 30 according to the open and closed states of the door 151. Switch the view between paths.

The first docking station 10 may include an interior extension tube 180 .

Internal extension tube 180 may be disposed in housing 110 . More specifically, inner extension tube 180 may be disposed in inner path 120 . The inner extension tube 180 may be disposed on the back surface where the first end of the outer path 30 is coupled to the third outer wall surface 111c. At this time, a hole passing through the third outer wall surface 111c may be formed in the third outer wall surface 111c to which the first end of the inner path 120 is coupled, thereby allowing the outer path 30 and the inner extension tube 180 to communicate with each other.

A first end of the inner extension tube 180 may be connected to the outer path 30 , and a second end thereof may be opened in the inner path 120 in a direction relative to the dust collection motor 130 . Since the second end of the inner extension tube 180 is opened toward the dust collection motor 130 , dust moving from the inside of the dust box 610 of the second sweeper 60 through the outer path 30 can pass through the inner extension tube 180 and the inner path 120 , and then pass through the dust collection The suction force of the motor 130 is collected in the dust collecting part 140.

At the same time, when the suction force is generated by the dust collection motor 130 of the sweeper system 1 according to an embodiment of the present invention, if any one of the external path 30 and the internal path 120 is opened according to the open and closed state of the door 151, then The remaining vacuum paths can be closed.

Referring to FIG. 15 , the inner extension tube 180 may be disposed such that the second end of the inner extension tube 180 is located above the door 151 when the door 151 is opened. If the door 151 is opened, the second end of the inner extension tube 180 is blocked by the door 151 . That is, if the door 151 is opened, the second suction path that is a path for sucking dust from the inside of the dust box 610 of the second cleaner 60 can be closed by the door 151 . At this time, the door 151 can be opened, so the first suction path connected to the dust box 516, the internal path 120 and the dust collecting part 140 of the first sweeper 50 can be opened, and therefore the suction force can only act on the first sweeper 50 On the dust in the dust box 516 (please see the direction indicated by the arrow in Figure 15).

On the contrary, if the door 151 is closed, the second end of the inner extension tube 180 can be opened toward the dust collection motor 130 and the dust collection component 140 and connected to the dust box 610 of the second sweeper 60 , the outer path 30 , and the inner extension tube. 180. The internal path 120 and the second suction path of the dust collecting component 140 are also opened. At this time, the door 151 is closed, so the dust box 516 of the first cleaning machine 50 is blocked by the door 151 . That is, at this time, the first suction path can be closed, and only the second suction path can be opened, so the suction force can only act on the dust in the dust box 610 of the second cleaner 60 (see the arrow in Figure 16 direction).

In this way, the path switching structure between the first suction path and the second suction path can selectively switch paths using the door 151 without the need for a separate path switching device (such as a valve, etc.). Therefore, the manufacturing cost of the sweeper system 1 can be reduced, and the structure and control of the sweeper system 1 can be simplified. Furthermore, since it is not necessary to provide a separate path switching device in the housing 110, the space in the housing 110 can be used more effectively.

Hereinafter, the coupling structure of the first docking station 10 and the second docking station 20 will be described with reference to FIGS. 17 and 18 .

17 is a view showing the lower end of the housing 110 of the first docking station; and FIG. 18 is a view showing a state in which the ground support is coupled to the lower end of the housing 110 of the first docking station when viewed from below.

A plurality of housing fastening holes 114 may be formed on the housing 110 of the first docking station 10 . At this time, the housing fastening hole 114 may be provided on the lower end of the housing 110 .

A plurality of upper body fastening holes 231 may also be formed on the upper surface 113 of the upper body 230 of the second docking station 20 . The upper body fastening hole 231 may be provided at a position corresponding to each of the housing fastening holes 114 .

The first docking station 10 and the second docking station 20 may be detachably coupled through the housing fastening holes 114 and the upper body fastening holes 231 . At this time, individually set fastening devices (such as fastening bolts, etc.) can be used.

Figure 17 shows the arrangement of the housing fastening holes 114 provided on the lower end of the housing 110. It is assumed that the user only purchases and uses the first stop 10. At this time, the housing 110 can be coupled to the ground support through the housing fastening hole 114 (see Figure 18).
