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 box of the sweeper. More specifically, the present invention pertains to a sweeper system capable of selectively switching between an internal path for picking up dust from a dust box of a first sweeper and a path for picking up dust from a dust box of a second sweeper. Switch suction path between external paths.

In general, a sweeper is a household appliance that uses electricity to suck up small debris or dust by drawing in air and fill it into a dust box contained therein, and is often referred to as a vacuum cleaner.

Such cleaning machines can be classified into manual cleaning machines and automatic cleaning machines, in which the manual cleaning machine is moved by a user for cleaning, and the automatic vacuum cleaner can be automatically driven for cleaning. Manual vacuum cleaners can be divided into canister vacuum cleaners, upright vacuum cleaners, hand-held vacuum cleaners, and stick vacuum cleaners according to the shape of the cleaning machine.

In the past, canister vacuum cleaners were widely used as household sweepers. But recently, more and more people use hand-held vacuum cleaners and stick vacuum cleaners, because the dust box and the cleaning machine body are integrated together to increase the convenience of use.

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

The purpose of hand-held vacuum cleaners is to maximize portability, and they are lighter in weight but shorter in length, so they should be used while sitting, so the cleaning area may be limited. Therefore, hand-held vacuum cleaners are used for cleaning localized places, such as table tops, sofas or the interior of a car.

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

Furthermore, recently, cleaning robots that can perform cleaning operations without user manipulation are also widely used. The cleaning robot automatically cleans the target area by sucking foreign objects such as dust from the floor while driving automatically on the area to be cleaned.

However, the conventional stick cleaner and the conventional cleaning robot have a problem in that each cleaner has a small-capacity dust box for storing collected dust, so it is inconvenient for the user 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 cleaner, has been proposed as a patent document.

This 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 the foreign objects collected in the dust collector . Also, 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, which is an invention for processing dust collected by a cleaning robot, has been proposed as a patent document.

US Patent No. 10463215 discloses a discharge station, which includes a base for accommodating a cleaning robot, and interfaces with the cleaning robot accommodated in the base. Also, 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 configures to collect dust only from the dust box of the stick 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 has a problem that it cannot be collected from both the dust box of the stick cleaner and the dust box of the cleaning robot dust.

Meanwhile, although stick vacuum cleaners and cleaning robots improve the convenience of users, due to structural shape limitations and technical problems, it is difficult to clean perfectly with only one vacuum cleaner. Therefore, users will purchase and use both stick cleaners and cleaning robots. Alternatively, after purchasing one type of cleaning machine, the user additionally purchases another type of cleaning machine.

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

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

In addition, since a user usually buys and uses a stick vacuum cleaner first and then buys a cleaning robot, it is necessary to develop a structure in which a docking station dedicated to the stick vacuum cleaner can be substantially coupled to the docking station dedicated to the cleaning robot.

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

1 and 2 , a sweeper 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 that defines an interior space for accommodating a plurality of components.

Also, 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 sweeper 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 "forward" may be defined as the direction facing the coupling 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 in which the housing 110 faces with respect to the opposite surface of the coupler 115 may be defined as the rear. Also, 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 provided may be the upper portion.

The outer path 30 may communicate with the interior of the housing 110 and the dust box 610 of the second sweeper 60 . The outer path 30 may be formed in a tubular shape defining a channel 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 .

3 shows the first sweeper 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 sweeper 50. FIG.

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

The sweeper body 510 of the first sweeper 50 may include: a suction part 511 to provide a path through which dust-containing air can pass; a dust separation part 512 to communicate with the suction part 511 and to separate the The sucked dust; the suction motor 513, which generates suction to suck in the air; the handle 514, which is held by the user; and the battery case 515, which is used to accommodate the battery.

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

Herein, the dust box 516 may communicate with the dust separator 512 and may store the separated dust in the dust separator 512 .

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 the air separated from the dust may flow to the suction motor 513 and then be discharged to the outside of the first sweeper 50 .

The discharge cover 5162 may be rotatably coupled to the open side of the dust box body 5161 . More specifically, the discharge cover 5162 may be coupled to the dust box body 5161 via the 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 the side close to the battery case 515 . The discharge cover 5162 can be rotated around the dust box hinge 5164 to open or close the dust box body 5161 .

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

The coupling lever 5163 may be provided to move in the longitudinal direction of the dust box body 5161 along the outer circumference 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 in the longitudinal direction of the dust box body 5161 (ie, the direction of releasing the hook coupling), the coupling hook extending from the discharge cover 5162 can be elastically deformed, and the discharge can be released The hook between the cover 5162 and the dust box body 5161 is coupled.

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 stop 10; and FIG. 6 is a view showing the arrangement relationship between the first cleaner 50 and the casing 110 and the arrangement structure of the outer wall surface of the casing 110.

As described 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 one outer wall surface. For example, the housing 110 may be formed in a shape similar to a square column.

An assembly including the dust collecting motor 130 , the inner path 120 and the dust collecting part 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 . Also, the ground support 112 may be detachably coupled to the lower end of the housing 110 . The bottom surface of the ground supporter 112 that contacts the ground may be disposed parallel to the ground, or may be disposed inclined at a predetermined angle to the ground. With this configuration, heavier components such as the dust collecting motor 130 accommodated in the housing 110 can be stably supported, so that even if the first cleaner 50 is coupled to the upper portion of the housing 110, the overall weight can be balanced.

Also, 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 contacting the ground, thereby preventing the sweeper dock from falling down and maintaining balance. For example, the 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 surface. 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 the walls face the first outer wall 111a, they are arranged counterclockwise in sequence (see FIG. 6).

The housing 110 can be opened to expose some components (eg, the dust collecting part 140 ) accommodated therein. 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 first outer wall surface 111a The left portion 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 111 a can be pressed toward the inside of the housing 110 , so that the coupling 115 formed on the first outer wall surface 111 a corresponds in shape to a portion of the cleaner body 510 of the first cleaner 50 . With this 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 . Herein, a portion of the first sweeper 50 may represent a certain area of the dust box 516 of the first sweeper 50 and a certain area of the battery housing 515 of the first sweeper 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 in the housing 110 of the first dock 10 to which the first sweeper 50 is coupled.

The dust box 516 and battery housing 515 of the first sweeper 50 may be coupled to the coupler 115 . Referring to FIG. 7 , the coupler 115 may include a 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 111a toward the inside of the housing 110 . In other words, the coupling surface 1151 may be referred to as 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 sweeper 50 or places the first sweeper 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 1151 a 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 1151 a may be formed to correspond to the shape of the dust box 516 to allow the dust existing in the dust box 516 to flow into the dust collecting part 140 . Specifically, the dust through hole 1151a may be formed in a shape corresponding to 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. A dust through hole 1151a may be formed to communicate with the inner path 120 .

The coupler 115 may include a dust box 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. Also, the dust box guide surface 1152 may be connected with the coupling surface 1151 .

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

Coupler 115 may include guide tabs 1153 . A 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 disposed to be 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, when the first cleaner 50 is coupled to the coupling surface 1151, convenience can be provided.

Coupler 115 may include coupler sidewalls 1155 . The coupler side walls 1155 may represent wall surfaces disposed on both sides of the coupling surface 1151 and may be vertically connected to the coupling surface 1151 . The coupler side wall 1155 may be connected to the first outer wall surface 111a. Also, 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 that connects to the dust box guide surface 1152 . Therefore, the first cleaning machine 50 can be prevented from shaking from side to side, and the first docking station 10 can stably accommodate the first cleaning machine 50 .

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

The coupling sensor may include a touch sensor. For example, the coupling sensor may include a microswitch. In this case, the coupling sensor may be provided on the guide protrusion 1153 . Therefore, if the battery case 515 of the first cleaning machine 50 is coupled between the pair of guide protrusions 1153 , the coupling sensor can sense the first cleaning machine 50 by being in contact with the battery case 515 .

The coupling sensor may include a non-contact sensor. For example, the coupling sensor may include an IR sensor. In this case, the coupling sensor may be provided on the coupling side wall 1155 and may be relative 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 supplying power to the first cleaning machine 50 , so as to 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 cleaning machine charging terminal 1156 may be disposed on the coupling surface 1151 . If the first sweeper charging terminal 1156 is coupled to the battery, power can be supplied to the first sweeper 50 .

The coupler 115 may further include a fixing member contact hole 1157 . The fixing 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 fixing 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 docking station 10 may include an internal path 120 .

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

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

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

The first docking station 10 may include a dust collecting part 140 .

Referring to FIG. 2 , the dust collecting part 140 may be accommodated in the housing 110 and may be disposed above the dust collecting motor 130 . Since the dust collecting member 140 is disposed above the dust collecting motor 130, if the dust collecting motor 130 generates suction, the dust sucked from the dust box 516 of the first cleaner 50 and the dust box 610 of the second cleaner 60 can be collected in the collection in the dust part 140 .

The dust collecting part 140 may collect dust through the first suction path, the inner path 120 and the dust collecting part 140 connected to the dust box 516 of the first cleaner 50 . Also, 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 collecting part 140 may be detachably coupled to the housing 110 . Therefore, if the case is opened, the dust collecting part 140 may be separated from the case 110 to be discarded, and then a new dust collecting part 140 may be coupled to the case 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 receive the dust in the dust collecting part 140 . Therefore, the dust collecting member 140 may be made of a breathable material, which cannot allow foreign matter such as dust to pass therethrough. For example, the dust collecting member 140 may be made of non-woven material and become hexagonal as its capacity increases.

Meanwhile, the first end of the inner path may be coupled to the dust through hole 1151 a, and the second end of the inner path 120 may be coupled to the dust collecting part 140 . Therefore, if the dust collecting motor 130 is driven to generate suction, the airflow can be formed from the first end to the second end of the inner path 120 . Air containing foreign objects flowing from inside the dust box 516 of the first sweeper 50 can flow through the inner path 120 to the dust collecting part 140 and then can escape from the dust collecting part 140 while leaving only the foreign objects in the dust collecting part 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 disposed on the coupler sidewall 1155 . Also, 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 cleaning machine 50 coupled to the coupling surface 1151 .

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

The securing member 161 may receive power from the securing motor 162 to move back and forth from the interior of the coupler sidewall 1155 of the coupler 115 toward the dust box. 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 portion of the fixing member 161 may be formed to correspond to the shape of the battery case 515 , and the shape of the lower portion of the fixing member 161 may be formed to correspond to the shape of the dust box body 5161 .

Such a configuration can prevent a separation space 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 the dust is sucked by the dust collecting motor 130 , the dust in the dust box 516 is prevented from being scattered to the outside of the first docking station 10 .

The anchor motor 162 may be powered to move the anchor member 161 . Specifically, the fixing member 161 may move in a direction to press the dust box 516 from the inside of the coupler side wall 1155 through the holder motor 162, thereby fixing the first cleaning machine 50 to the first docking station 10, or may be moved from the fixing member 161 presses the position of the dust box 516 and moves to the inside of the coupler side wall 1155, thereby releasing the first sweeper 50 from the first docking station.

When coupled to the first sweeper 50 , a stationary seal 163 may be provided on the dust box guide surface 1152 to hermetically seal the dust box 516 . When coupled to the dust box 516 of the first sweeper 50, such a configuration can press the fixed seal 163 through the weight of the first sweeper 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 an arrangement relationship in a state in which both the discharge cover 5162 and the door 151 of the first cleaner 50 are opened.

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 .

The door 151 may be provided on the coupler 115 and may be configured to communicate the exterior of the housing 110 with the interior path 120 . More specifically, the door 151 may be coupled with the door hinge 154 in the housing 110 and may be rotated 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 the upper end of the dust through hole 1151a on the side opposite to the coupling surface 1151, and the door 151 may be coupled to the door hinge 154 to be located at a position to close the dust through hole 1151a .

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

Also, the state in which the door is closed may represent a state in which the door 151 is rotated around the door hinge 154 in the direction R2 (the second direction) relative to the first direction to close the dust through hole 1151a, so the outside of the housing 110 does not communicate with the inside path 120 connections. In a state where the door 151 is closed, since the door 151 is located at a position to block the dust through hole 1151a, 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 the outside of the case 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 a whole circle, and the first door 151a and the second door 151b may be rotatably coupled at the position of the reference line, the first door 151a and the second door 151a and the second door The gates 151b are divided along this reference line. For example, the first door 151a and the second door 151b may be hinged at the location 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. Also, the reference line may be formed such that the area of the first door 151a is larger than that of the second door 151b.

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

For example, the door arm 152 may include: a first door arm 152a; and a second door arm 152b. The 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 the 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. The 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 .

When the door 151 is pulled by the door arm 152 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 . Meanwhile, if the door arm 152 pushes the door 151 when the door 151 is opened, the door 151 may rotate toward the outside of the housing 110 of the first docking station 10 along the second direction R2.

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

Meanwhile, 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 be bent relative to the hinge where the first door 151a and the second door 151b are coupled. At this time, the first door 151a may be disposed to be substantially perpendicular to the main axis A1 of the case 110, and the second door 151b may be disposed to be substantially parallel to the main axis A1 of the case 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 collecting motor 130 .

The door motor unit 153 may provide power to the door arm 152 for rotating the door 151 . 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 , which is the direction in which the door arm 152 pulls the door 151 toward the interior of the housing 110 . Also, the term “rearward” may refer to the second direction R2, which is the direction 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 worm gear 153b coupled to the shaft of the door motor 153a to receive power; and a worm gear 153c meshed with the worm gear 153b to receive rotational force and Change the direction of rotation. Here, the first gate arm 152a may be rotatably coupled to the 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 cover 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 cleaning machine 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 sweeper 50 is coupled to the coupler 115 , the pushing protrusion 171 may be located at a position where the coupling rod 5163 can be pressed. The pushing protrusion 171 can linearly move back and forth to press the coupling lever 5163 . Specifically, the pushing protrusion 171 may be provided on the dust box guide surface 1152 . A protrusion moving 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 moving hole. The pushing protrusion 171 may be coupled to the cap-opening gear 172 to move along the cap-opening gear 172 .

The cap-opening motor may provide power for moving the push tab 171 to the cap-opening gear 172 .

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

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

In other words, when the cleaning machine body 510 of the first cleaning machine 50 is fixed to the coupling 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 sweeper 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 dock 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. Also, if the first sweeper 50 is coupled to the coupling 115 of the housing 110 , the longitudinal axis A2 of the dust box 516 of the first sweeper 50 may be disposed substantially perpendicular to the main axis A1 of the housing 110 . At this time, the first cleaning machine 50 may be supported such that the longitudinal axis A3 of the suction member 511 of the first cleaning machine 50 is substantially parallel to the main axis A1 of the housing 110 .

Meanwhile, 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 part 140 through the suction force of the dust collecting motor 130, it can be The user who empties the dust box of the stick vacuum cleaner eliminates the inconvenience. Also, when the user empties the dust box of the stick vacuum cleaner by himself, the dust can be prevented from escaping.

12 is a perspective view of the second docking station 20; and FIG. 13 is a view showing that the dust box 610 of the second cleaning machine 60 and the external path 30 are communicated with each other in a state where the second cleaning machine 60 is docked on the second docking station 20 method's 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, which is automatically driven to perform cleaning operations.

The second cleaning machine 60 can automatically clean a predetermined area by absorbing foreign objects such as dust from the floor while the area to be cleaned moves by itself. The second sweeper 60 may include: a distance sensor that detects the distance to obstacles, such as furniture, office supplies or walls installed in the sweeping area; and left and right wheels for movement. The second sweeper 60 may be docked on or coupled to the second dock 20 . The dust sucked into the dust box 610 of the second cleaner 60 may be collected in the dust collecting part 140 through the external path 30 .

The second sweeper 60 may include a second sweeper 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 sweeper dust discharge hole 620 may be in the shape of a rectangular hole.

The second sweeper 60 may include a second sweeper discharge cover 630 . At this time, the shape of the second sweeper discharge cover 630 may be formed to correspond to the shape of the second sweeper dust discharge hole 620 so as to close the second sweeper dust discharge hole 620 . Therefore, the second sweeper discharge cover 630 may be provided in the second sweeper 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, while a second side thereof may form a free end. Through such a configuration, if the dust collecting motor 130 generates suction, the free end can move downward while the fixed end is fixed, thereby opening the second cleaning machine dust discharge hole 620 . If the dust collecting motor 130 stops operating, the free end of the second cleaning machine discharge cover 630 can move upward, thereby closing the second cleaning machine dust discharge hole 620 . According to the moving direction of the free end, the second sweeper discharge cover 630 may make the dust box 610 of the second sweeper 60 and the external path 30 communicate with each other or close relative to each other.

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

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 be docked on the second docking station 20 . The second sweeper 60 may cling to the lower body 210 to be docked thereon.

The inclined part 210a may be provided on the central portion 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 member 210 a may be formed of a plurality of inclined surfaces having 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 rolling parts 210b through which left and right wheels of the second sweeper 60 pass when the second sweeper 60 is moved to be docked. The rolling parts 210b may be disposed 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 uneven parts may be formed on the upper surface of each rolling part 210b to prevent the left wheel and each of the right wheels slips.

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

Moreover, the lower body 210 may include a second cleaning machine charging terminal 212 , which 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 can be electrically connected to each other, and power can 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 side ends of the lower body 210 and may extend upward from the lower body 210 . The side body 220 may be disposed on the left end or the right end of the lower body 210 to define a side appearance of the second docking station 20 .

When the second sweeper 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 sweeper 60 to be spaced apart from the upper surface by a predetermined distance . 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 sweeper 60 is butted. At this time, the second docking station 20 may further include a path supporter 250 connected to the rear body 240 .

The path supporter 250 may extend upward from the upper surface 113 of the casing of the upper body 230 to be spaced apart from the upper surface 113 by a predetermined distance, and may accommodate a portion of the outer path 30 therein. Path supports 250 may be provided to accommodate and support the outer path 30 . For example, the path support 250 may be in the shape of a cylinder or a square column. Herein, the path support 250 may have any shape capable of receiving and supporting the outer path 30 . Of course, the path supports are 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 casing opened only on the side where the second cleaner 60 is docked. Since the second docking station 20 is arranged to open only at the side where the second cleaning machine 60 is docked, the first docking station 10 coupled to the upper portion of the second docking station 20 can be stably supported in the structure.

Meanwhile, an accommodation space for accommodating a part of the outer 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 outer path 30 may be coupled with the suction hole 211 in the accommodation space. The second end 30 of the outer path 30 may be coupled to the third outer wall surface 111 c to be connected with the inside of the housing 110 .

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

The first outer path may be vertically arranged in a direction in which the third outer wall surface 111c of the housing 110 to be described later is arranged. Also, the upper end of the first outer path may be connected to the inner extension pipe 180 through the third outer wall surface 111 c of the housing 110 . Since the inner extension pipe 180 to be described below is provided on the inner path 120 , the first outer path may communicate with the inner path 120 .

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

Such a configuration can form a second suction path in which dust is sucked and moved to the dust box 610 , the outer path 30 , the inner path 120 , and the dust collecting member 140 of the second sweeper 60 .

As such, the sweeper system 1 including the first dock 10 , the second dock 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 remove the dust from the dust box 516 and the dust box 610 by himself, so that the convenience can be maximized.

Hereinafter, a path switching structure between a dust suction path passing through the inner path 120 and a dust suction path passing through the outer path 30 in the sweeper 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 pipe 180 and the door 151 in a state where the door is opened; and FIGS. 15 and 16 are views showing the inner path 120 and the outer path 30 according to the open and closed states of the door 151 Switches between views of the path.

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

An inner extension tube 180 may be provided in the housing 110 . More specifically, an inner extension tube 180 may be disposed in the inner path 120 . The inner extension tube 180 may be provided 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 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 pipe 180 to communicate with each other.

The first end of the inner extension tube 180 may be connected to the outer path 30 , and the second end thereof may be opened in the direction relative to the dust collection motor 130 in the inner path 120 . Since the second end of the inner extension pipe 180 is opened toward the dust collection motor 130, the 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 pipe 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 .

Meanwhile, when suction is generated by the dust collecting motor 130 of the sweeper system 1 according to an embodiment of the present invention, if any one of the dust suction paths in the outer path 30 and the inner path 120 is opened according to the open and closed states of the door 151, then The remaining vacuum paths can be closed.

Referring to FIG. 15 , the inner extension pipe 180 may be arranged such that the second end of the inner extension pipe 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 pipe 180 is blocked by the door 151 . That is, if the door 151 is opened, the second suction path which 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 may be opened, and thus the first suction path connected to the dust box 516 of the first cleaner 50, the inner path 120 and the dust collecting part 140 may be opened, and thus the suction force may only act on the first cleaner 50 on the dust in the dust box 516 (see the direction of the arrow in Figure 15).

Conversely, if the door 151 is closed, the second end of the inner extension pipe 180 can be opened toward the dust collecting motor 130 and the dust collecting part 140 and connected to the dust box 610 of the second cleaning machine 60 , the outer path 30 , and the inner extension pipe 180, the inner path 120 and the second suction path of the dust collecting member 140 are also opened. At this time, since the door 151 is closed, the dust box 516 of the first cleaner 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 can only act on the dust in the dust box 610 of the second cleaning machine 60 (see the arrow in FIG. 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 requiring a separate path switching device (such as a valve or the like). 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. Also, since it is not necessary to provide a separate path switching device in the casing 110, the space in the casing 110 can be used more efficiently.

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 casing 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 casing 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 case fastening hole 114 may be provided on the lower end of the case 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 holes 231 may be provided at positions corresponding to each of the case 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 . In this case, a separately provided fastening device (such as a fastening bolt, etc.) can be used.

FIG. 17 shows the arrangement of the case fastening holes 114 provided on the lower end of the case 110 . It is assumed that the user only purchases and uses the first docking station 10 .
