Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the embodiments presented below, and those skilled in the art who understand the spirit of the present invention can add, change, delete, and add components to other embodiments included within the scope of the same idea. Thus, it can be easily proposed, but it can be said that this is also included within the scope of the inventive concept.

1 is a perspective view of an air cleaning system according to an embodiment.

Referring to FIG. 1, in the air cleaning system according to the embodiment, at least two air purifiers (2) (3) capable of independent operation and the at least two air purifiers (2) (3) can be mounted. A cradle 1 is included.

Since the cradle 1 can perform the function of an air purifier, it may be referred to as a cradle air purifier 1. The cradle air purifier may not be provided with the function of an air purifier. The cradle air purifier may be referred to as a cradle by referring to a case in which the function of the air purifier is provided and a case in which it is not provided.

The at least two air purifiers (2) (3) may stand in a tower shape vertically up and down while seated on the cradle air purifier (1). The at least two air purifiers 2 and 3 may be referred to as tower air purifiers.

The cradle air purifier 1 may be provided in a flat shape that is long left and right relative to the front. The tower air purifier may include a first tower air purifier (2) placed on the left side of the cradle air purifier (1), and a second tower air purifier (3) placed on the right side of the cradle air purifier (1). have. More tower air purifiers may be provided. However, since there is a restriction on the discharge direction due to interference between the clean air discharged from the tower air purifier, two pairs of left and right tower air purifiers 2 and 3 can be preferably proposed.

Handles 22 and 32 are provided on the top of the tower air purifier 2 and 3, and a user can move or handle the main body 21 and 31 of the tower air purifier while holding the handle. The handle may be fixed to the side of the main body by the hinge structure of the main body 21 and 31. The handles 22 and 32 are provided to be rotatable, so that when the user is not in use, the handle is supported on the side of the main body so as not to interfere with air discharge.

As already described, the tower air purifier (2) (3) may be placed on the cradle air purifier (1).

Since the tower air purifiers 2 and 3 are provided in a tower shape vertically, there is a concern of overturning. Since the tower air purifier (2) and (3) can be frequently moved by the consumer, it is preferable to place the tower air purifier (2) and (3) in a predetermined position for charging and storage.

In order to satisfy the above two needs, it is preferable that the tower air purifier (2) and (3) be safely seated at a predetermined position of the cradle air purifier (1).

2 and 3 are views for explaining the seating function of the tower air purifier, FIG. 2 is a perspective view of the cradle air purifier, and FIG. 3 is a schematic cross-sectional view of A-A' of FIG.

2 and 3, the cradle air purifier 1 is provided elongated left and right when viewed from the front. The cradle air purifier 1 may have a predetermined height and may have an inclined surface 15 that is provided to be inclined downward as it goes forward. The upper surface of the cradle air purifier 1 may be provided to have a lower height as it moves from the rear to the front.

The upper surface of the cradle air purifier 1 may be recessed downward to provide seating grooves 13 and 14. The seating grooves 13 and 14 may be provided on the left and right sides of the upper surface of the cradle air purifier 1 to correspond to the lower surfaces of the tower air purifiers 2 and 3. The base 21 of the tower air purifier 2 and 3 may be placed in the seating grooves 13 and 14. The bottom surface inside the seating groove may be provided flat to prevent the tower air purifier (2) (3) from falling.

An arc-shaped groove (not shown) is provided on the bottom surface of the seating groove, and an arc-shaped protrusion (not shown) corresponding to the long groove is provided on the bottom surface of the base, and the installation location of the tower air purifier is particularly installed. The angle can also be guided accurately. The installation position may exemplify a relative position of the tower air purifier and the seating groove in all directions, front, rear, left and right. For example, the front of any one tower air purifier and the front of the corresponding seating groove may coincide with each other.

In this case, the installation direction of the tower air purifier with respect to the seating groove and the installation direction between the tower air purifiers are accurately set, so that the discharge direction of the clean air discharged from the air purifier can be controlled.

In order to prevent the tower air purifier (2) (3) from falling, the seating grooves (13, 14) are provided by being recessed to a predetermined depth. The rear portion of the seating grooves 13 and 14 is provided as the highest wall and can withstand an external force applied from the front. Since the side portions of the mounting grooves 13 and 14 gradually decrease in wall height toward the front, they can withstand the external force from the side of the tower air purifier 2 and 3.

The front portion of the seating groove is provided without height, so that the user can conveniently place the tower air purifier (2) (3) in the seating grooves 13 and 14 through the front portion. The front portion of the seating groove is provided without height, so that even when a user takes out the tower air purifier (2) (3), it can be conveniently taken out through the front portion of the seating groove. Here, the word that there is no height of the seating groove can be understood as meaning that it is the same height as the lower wall 12 and does not become higher.

In order for the user to accurately seat the tower air purifiers 2 and 3 in the seating groove, a first lamp 17 may be provided around the bottom edge of the seating groove. In order to instruct the user of the inclination angle of the seating grooves 13 and 14, a second lamp 18 may be provided around the upper edge of the seating grooves 13 and 14. The user, by comparing the first and second lights 17 and 18, not only estimates the height of the seating grooves 13 and 14, but also sees the bottom surface of the seating grooves 13 and 14, The tower air purifier (2) (3) can be mounted there.

When the tower air purifier (2) (3) is placed in the seating groove (13) (14), the tower air purifier (2) (3) is supported on the flat upper surface of the lower wall (12) and the front surface of the rear wall (11). Can be. The tower air purifier (2) (3) is also supported on the sidewalls of the seating grooves (13, 14) to prevent fall. In the air cleaning system of the embodiment, since the cradle air purifier 1 is long left and right, the user's approach is much more in the front approach than in the rear approach. Therefore, it is possible to sufficiently prevent the tower air purifier (2) (3) from falling due to external force.

The seating grooves 13 and 13 may further perform the following functions as well as preventing the tower air purifiers 2 and 3 from falling.

First, wired or wireless charging between the tower air purifier (2) (3) and the cradle air purifier (1) by wired or wireless at a predetermined position, and second, two or more air purifiers operate in combination with each other to perform optimal cooperative operation, third, It is to secure a stable communication function between the air purifiers (1) (2) and (3).

At least a filter member and a fan are provided in the inner space of the cradle air purifier 1, so that air may be sucked through the suction part 121 and air may be discharged through the discharge part 125.

As the filter member, the first filter 122 and the second filter 123 may be provided in the order of air flow. The first filter 122 may be a filter having a larger manure mesh than the second filter 123. The cradle air purifier 1 is a device that operates close to the floor surface, and relatively large amounts of dust from the indoor floor may be introduced. Therefore, it is preferable to filter out large dust in advance through the first filter 122.

The fan 124 may be provided on the downstream side of the filters 122 and 123 to provide the force of air flow.

The discharge unit 125 may be provided smaller than the suction unit 121 to increase the flow rate of the clean air to be blown. Accordingly, by removing dust from the floor surface affected by the cradle air purifier 1, it is possible to increase the satisfaction felt by a user familiar with the sedentary culture.

5 is a schematic cross-sectional view of the tower air purifier, and FIG. 6 is an enlarged view of an upper portion of the tower air purifier.

Referring to FIGS. 5 and 6, the tower air purifiers 2 and 3 may be provided in a substantially vertically long cylinder, and a base 21 for seating may be provided at the lower end.

A suction grill 22 having a plurality of holes may be provided below the outer wall 27 of the tower air purifier 2 and 3.

In the inner space of the tower air purifier (2) (3), from the bottom to the top, a filter (23), a fan (24) supported by a fan housing (25), an air guide (26) for adjusting the blowing direction Can be placed. By the negative pressure provided by the fan 24, the clean air passing through the filter 23 may be blown by the air guide 26 with the wind direction adjusted.

A handle 22 is provided at the upper end of the outer wall 27 so that the user can easily lift and move the tower air purifiers 2 and 3.

A display 28 may be provided on the upper surface of the air guide 26. In the display 28, a first display mode for the tower air purifier (2) (3) itself, a second display mode for the entire air cleaning system, or a first display mode and the second display mode are mixed and used. The third display mode to be displayed may be displayed. The display mode can be performed similarly to the cradle air purifier.

Five wireless transmission/reception units 281 may be provided on an upper edge of the tower air purifier 2 and 3. The wireless transmission/reception unit 281 of the tower air purifier (2) (3) performs the same configuration, the same function, and the same function as the wireless transmission/reception unit 111, 112, 113 of the cradle air purifier 1 can do.

It has already been described that the wireless transmitting/receiving unit 281 can find out the indoor space in which the air cleaning system according to the embodiment is placed as map information.

The air cleaning system of the embodiment may be operated using the map information identified by the cradle air purifier 1 and the tower air purifier 2 and 3. By cooperating with the cradle air purifier (1) and the tower air purifier (2) (3) provided to the air cleaning system, optimal cooperative operation can be performed when the air purifier is operated for the indoor space. have.

By using the map information on the display, the user can intuitively know the operating state of the air cleaning system.

7 is a view for explaining the operation of the air cleaning system according to the embodiment.

Referring to FIG. 7, the tower air purifiers 2 and 3 are mounted on the cradle air purifier 1. A display 152 may be provided on the inclined surface 15. The display 152 is currently in the second display mode showing the operation of the entire air cleaning system according to the present embodiment.

On the display 152, an indoor space based on the map information may display boundary line information 154, self-location information 153, and flow information 155 indicating wind direction, air volume, wind speed, pollution degree, etc. have.

The boundary line information 154 may indicate a boundary line of an indoor space based on map information identified by the wireless transmission/reception unit.

The magnetic location information 153 can identify the location where the current air cleaning system is placed, more precisely, the location where the cradle is placed, together with the boundary line information 154 on the map information, and display it together with the boundary line information 154. have.

The flow information 155 may indicate the wind direction/air volume/wind speed/pollution degree, etc. of the clean air blown when the air cleaning system of the embodiment is operated according to an operation state selected corresponding to the current state. Exemplarily, the direction of the wind may use the direction of the arrow, the air volume may use the thickness of the arrow, the wind speed may be represented by the length of the arrow, and the pollution degree may be represented by the color of the arrow.

In FIG. 7, it can be seen that the clean air turns and exits the concave space of the indoor space according to the boundary line information 154. Display units 156 and 157 may be provided in front of the display 152 to indicate the charging status of each of the tower air purifiers 2 and 3.

FIG. 8 is an enlarged view of the display, and a cooperative operation is described with reference to FIG. 8.

The cooperative operation can be understood by explaining the discharge direction of the clean air from the air cleaning system according to the embodiment. Referring to FIG. 8, it can be seen that the first tower air purifier 2 blows clean air to the left, and the second tower air purifier 3 blows clean air forward.

According to the blowing direction, it is possible to obtain the advantage of blowing clean air not only in the front space where the air cleaning system is located, but also in the wide space on the left side of the air cleaning system. The first tower air purifier 2 may also increase the air volume and blow the clean air further.

By the cooperative operation selected according to the current state, the indoor space in which the air cleaning system is placed can be identified by itself, and the best air cleaning effect can be achieved by using at least two air purifiers. Of course, the user does not need to know the structure of the indoor space. Here, it can be seen through the above embodiment that the cooperative operation is clearly distinguished from a combined operation in which a plurality of air purifiers are simply operated together.

The difference between the combined operation and the cooperative operation will be described later.

9 is a view showing a display of the tower air purifier.

Referring to FIG. 9, in a current state, the first display mode is implemented. The display 28 variously displays the operating status of the tower air purifier itself. The display unit'space learning' as one of the buttons in the display is a button for instructing to grasp map information on the indoor space where the tower air purifier is currently placed.

When the spatial learning is performed, map information may be obtained by grasping an indoor space using the wireless transmission/reception unit 281, and clean air may be blown using the acquired map information.

The driving by the spatial learning may be performed not only by the cooperative operation, but also by a single operation. For example, when referring to the boundary line information 154, if the position where the tower air purifier itself is placed alone is a corner portion, clean air may be blown while rotating only 90 degrees inside the corner portion.

In the current state, the display 28 displays only its own driving state as the first display mode. If the boundary line information 154 or the flow information 155 is displayed in one area of the display 28 together with the current state, the display mode is the first display mode and the second display mode. It can be referred to as the third display mode.

10 is a system block diagram of an air cleaning system according to an embodiment.

Referring to FIG. 10, a detailed configuration of a third air purifier, a first air purifier 480 connected to the communication unit 450 of the third air purifier, the third air purifier, or a third air purifier connected to the first air purifier. 2 air purifier 470 is shown. The third air purifier may be illustrated as the cradle air purifier 1, and the first and second air purifiers may be illustrated as first and second tower air purifiers 2 and 3, respectively.

The third air purifier is provided with a surrounding space determining unit 410 to obtain map information of an indoor space. The peripheral space determination unit 410 may include a wireless transmission/reception unit 411 and a mapping unit 412. The wireless transceiver 411 may exemplify a wireless transceiver 111 installed in the cradle air purifier. The mapping unit 412 may be a block including a mapping processor that provides map information of an indoor space by using a transmission/reception signal from the wireless transmission/reception unit 411.

A driving mode for a current indoor space may be determined using map information provided from the mapping unit 412. The space operation determination unit 420 determines the overall direction of the public hearing operation for the current indoor space using the map information. For example, if the current air purifier is placed at a 90 degree corner of an indoor space, the space operation determination unit 420 may allow the clean wind of the air purifier to be discharged only to the inside of a 90 degree angle.

The control unit 400 may determine operating conditions of the first, second, and third air purifiers by using various pieces of information previously stored in the memory 460. For this, the control unit 400 is provided with first, second, and third air purifier control modules 401, 402, and 403. The first, second, and third air purifier control modules 401, 402, and 403 may determine the operating conditions of the air purifier by checking the location and installation conditions of the air purifier associated with each control module.

The boundary line information 154 and the magnetic location information 153 on the drawing shown in FIG. 8 will be described as an example.

The space operation determination unit 420 may determine that it is preferable that clean air is provided forward and to the right at the current position, that is, in the upper right corner in FIG. 8. At this time, the reference of the direction may be based on the front of the cradle air purifier 1 itself.

In this case, three air purifiers can be modularized in the air cleaning system. The operating conditions for each air purifier for cooperative operation of each air purifier may be determined by the respective controllers 401, 402, and 403.

For example, when the cradle air purifier 1 does not perform air cleaning operation and is based on the front view, the first tower air purifier 2 blows only completely to the left, and the second tower air The purifier 3 can be blown only forward. In this case, the reason that the cradle air purifier is not operated may be because there is no user in the immediate front, so that air cleaning on the floor surface is not required.

This will be described with reference to FIG. 10 again.

When the operating condition of the air purifier is determined, the controller of the third air purifier may transmit a signal to the air purifier 430 so that the third air purifier itself may be driven. The third air purifier may transmit a control signal to the first air purifier and the second air purifier through the communication unit 450.

The ball receiving unit 430 may include a fan driving unit 432 and an additional driving unit 431. The additional driving unit 431 may include an operation determination of the air guide 26 and the like.

The control unit 400 outputs the driving state through the display unit 440 so that the user can check it. The mode of the display unit 440 may be previously selected from among the first, second, and third display modes.

This embodiment shows an example in which one air purifier is designated as the main (cradle air purifier in the embodiment), and the other two air purifiers (tower air purifier in the embodiment) are driven according to the instruction of the main. .

However, the present invention is not limited thereto, and other embodiments may be further provided.

For example, if the cradle air purifier 1 is not suitable for the wireless transmission/reception unit 111 to be installed, the tower air purifier 2 and 3 may be equipped with a wireless transmission/reception unit 281. The information of the wireless transmission/reception unit may be transmitted to the cradle air purifier 1 before or after being processed as mapping information.

For example, at least one of the space operation determination unit 420 and the control modules 401, 402, and 403 of each air purifier may be provided to at least one of the tower air purifiers.

For example, the control modules 401, 402, and 403 are provided only to the air purifier to which they belong, and their control state may be determined and operated by themselves.

A method of controlling an air cleaning system according to an embodiment will be described.

11 is a diagram illustrating a control method of an air cleaning system according to an embodiment.

Referring to FIG. 11, first, map information is obtained (S1). The map information corresponds to an indoor space and may be performed by the wireless transmission/reception unit and the mapping unit.

After that, the space operation is determined by using the map information and the resources of the air cleaning system (S2). The space operation is to determine the operating conditions that the air cleaning system must currently perform for the space specified by the map information.

For example, there has been an example of blowing air within an angle range of 90 degrees if it is placed in a corner. Accordingly, it is possible to prevent clean air from blowing into the wall. Furthermore, if the indoor space is square, air can be blown in the direction of 45 degrees from the corner to most preferably perform the air cleaning action for the entire space.

At this time, the combined operation may be determined.

The combined operation is a final operation result when at least two air purifiers provided in the air cleaning system are operated as a single unit. In other words, the determination of the combined operation may mean a consequential sum of the air purifier operations obtained by operating the at least two air purifiers together for the space.

After that, the operation information for each module is provided (S3). In this case, the cooperative operation may be determined. In other words, in the case of FIG. 8, the first tower air cleaner blows clean air to the left, and the second tower air cleaner blows clean air forward.

In the case of FIG. 8, unlike the case where each tower air purifier is operated in the cooperative operation, when only the combined operation is performed, it may be determined that it is best to blow air together with all the tower air purifiers in an oblique left direction. .

After that, each module may respond to and perform a public hearing action (S4).

In the case of an embodiment, the module may include the cradle air purifier, the first tower air purifier, and the second tower air purifier.

12 and 13 are views for explaining energy supply to the tower air purifier, FIG. 12 is a cross-sectional view of a central portion of a seating groove, and FIG. 13 is a partial rear view of the tower air purifier.

12, a wireless charging module 131 provided in the seating grooves 13 and 14 while being accommodated in the lower wall 12, and a first provided on the lower surface of the tower air purifier 2 and 3 2 wireless charging module 222 is shown.

The batteries inside the tower air purifiers 2 and 3 may be charged by the coupling action of the wireless charging modules 131 and 222.

Referring to FIG. 13, a space in which an outlet 221 is accommodated is provided above the lower base of the tower air purifier, and the tower air purifier may receive wired power.

The tower air purifiers 2 and 3 may be wirelessly charged when placed on the cradle air purifier 1, and can be charged by wire when separated from the cradle air purifier 1. Accordingly, in any case, the tower air purifier can perform an air cleaning function without inconvenience of supplying energy.

In the case of the above-described embodiment, clean air can be supplied based only on map information about a space that can be grasped by the air purifiers (1), (2), (3). For example, it is not possible to take into account the back of a wall where the signal light from the wireless transmission/reception unit cannot reach. Even if map information is obtained by moving the tower air purifiers 2 and 3, it is quite difficult to supply clean air based on comprehensive map information of an indoor space.

Meanwhile, the interior space is partitioned from each other by walls and doors. In particular, in each room partitioned by a door, it is difficult to supply clean air with an air purifier placed indoors. In the case of each room partitioned by a door, it may not be necessary to supply clean air depending on whether the door is opened or closed. For example, in the case of a room that has not been used for a long time and is closed, there is no need to consider it as map information that supplies clean air.

In the following embodiments, in view of the above-described problems, an air cleaning system capable of supplying clean air based on map information of the entire indoor space and a control method of the air cleaning system are proposed. In addition, we propose an air cleaning system and a control method of the air cleaning system that can supply optimal clean air by referring to map information of an indoor space that changes in real time.

14 schematically shows the configuration of an air cleaning system according to another embodiment.

Referring to FIG. 14, in the air cleaning system according to the present embodiment, a robot cleaner 500 that finds map information of an indoor space, a robot cleaner 500 that communicates with the robot cleaner 500 to obtain map information, and the obtained map Cradle air purifiers (1) and tower air purifiers (2) (3) that utilize information for air cleaning operation may be included.

The robot cleaner 500 may obtain map information by finding the structure of an indoor space through autonomous driving. The air purifiers (1) (2) and (3) may receive the map information in a separated state without being gathered.

Instead of the robot cleaner 500, any movable object that moves for a certain purpose and obtains map information of a space in which it is placed may be used in response to the movement. As an example of the moving object, the robot cleaner 500 is preferable. As the moving object, any device such as a drone, a surveillance robot, a transfer robot, a medical robot, and a vehicle may be used.

The moving object can move by itself without assistance from the outside. The moving object can acquire, store, and transmit map information to other devices without assistance from outside. The moving object may receive instructions from other external devices and users. The moving object may perform its own purpose by targeting a predetermined predetermined space. The moving object may have a predetermined purpose that requires movement as well as its own movement. The moving object may have a predetermined algorithm for movement.

However, as a preferred embodiment, the map information obtained by the robot cleaner 500 is transmitted to the cradle air purifier 1, and the cradle air purifier 1 utilizes the map information to use the map information for the air purifier 1 ( 2) It is possible to determine the operation mode of (3). In this way, the cradle air purifier 1 may function as a main among the three air purifiers 1, 2, and 3. However, the present invention is not limited thereto, and each may be used individually, and of course, the tower air purifiers 2 and 2 may operate as a main unit.

The air purifiers (1) (2) and (3) having obtained the map information may include a map where it is preferable to place each air purifier without staying in the combined operation and the cooperative operation.

As a preferred process, the robot cleaner 500 may perform cleaning in real time while moving the indoor space as a whole. The current map information of the indoor space acquired during cleaning is an area where clean air needs to be supplied at the present time and the clean air of the air purifiers 1, 2, and 3 must be supplied. Therefore, if the air purifier is operated based on the current map information, it is possible to supply more optimal clean air to the entire indoor space.

According to this, although included in the indoor space, spaces that do not require supply of clean air, such as a room not used by the user for a long time, and a clothes room that has been closed for a long time, may not be included in the current map information. Accordingly, a more efficient air cleaning operation can be performed.

The configuration and operation of the robot cleaner will be described first.

15 and 16 are perspective views and block diagrams of a robot cleaner.

15 and 16, the robot cleaner 500 performs a cleaning operation while traveling in a predetermined cleaning area. The robot cleaner 500 may include a casing 510, a driving unit 520, a suction unit 530, an image input unit 550, an image processing unit 560, a storage unit 570, and a control unit 580. I can.

The casing 510 forms the exterior of the robot cleaner 500. Inside the casing 510, parts constituting the robot cleaner 500, that is, the driving unit 520, the suction unit 530, the position detection unit 540, the image input unit 550, and the image processing unit 560 ), a storage unit 570 and a control unit 580 may be installed.

The driving unit 520 provides a driving force for driving the robot cleaner 500. The driving unit 520 may include travel motors 521 and 522 and travel wheels 523 and 524 rotated by the travel motors 521 and 522. In this case, the travel motors 521 and 522 may include first and second travel motors 521 and 522 that are independently controlled from each other. The driving wheels 523 and 524 may include first and second driving wheels 523 and 524 respectively connected to the first and second travel motors 521 and 522. Accordingly, by adjusting the rotation direction or/and the rotation speed of the first and second travel motors 521 and 522, the driving direction and speed of the robot cleaner 500 may be adjusted.

The suction unit 530 provides a driving force for sucking foreign substances into the interior of the casing 510, that is, the interior of the robot cleaner 500. For example, the suction unit 530 may include a suction motor 531, a suction fan 533 rotated by the suction motor 531, and the robot cleaner 500 by rotation of the suction fan 533. ) May include a dust collecting member 535 for collecting foreign substances sucked into the inside.

The position detection unit 540 detects a change in a position according to the movement of the robot cleaner 500 and detects the position of the robot cleaner 500, for example, an amount of movement from the initial position, and substantially the robot cleaner 500 Detect the location information of 500. To this end, the position detection unit 540 may include an encoder that detects the number of rotations of the first and second travel motors 521 and 522 in order to detect a movement amount of the robot cleaner 500.

The image input unit 550 is installed on one side of the casing 510. The image input unit 550 inputs an image of a cleaning area corresponding to the front in the driving direction of the robot cleaner 500. For example, as the image input unit 550, a camera that photographs an image of a subject may be used.

The image processing unit 560 processes the image input by the image input unit 550 to extract feature points from the image. For example, when an image input by the image input unit 550 is converted into a frequency domain, a corner portion, which is an area having a relatively large frequency variation, may be extracted as a feature point.

The storage unit 570 stores the feature points extracted by the image processing unit 560 and location information of the robot cleaner 500 detected by the position detection unit 540. In the storage unit 570, as will be described later, a map created by the control unit 580 may be stored, and various information necessary for the operation of the robot cleaner may be stored. In the present embodiment, the storage unit 570 may include a nonvolatile memory. Accordingly, the above-described information may be stored in the storage unit 570 regardless of on-off of power supplied to the robot cleaner 500.

The control unit 580 controls the operation of the robot cleaner 500, that is, the operation of the traveling unit 520 and the suction unit 530. The controller 580 may create a map for an area in which the robot cleaner 500 performs a cleaning operation, that is, a cleaning area.

In this case, when the cleaning area is composed of a plurality of areas partitioned from each other, the control unit 580 may create a map for each area and use this to create a map for the entire cleaning area.

The control unit 580 may store the created map of the cleaning area in the storage unit 70. The controller 80 controls the operation of the robot cleaner 500 to perform a cleaning operation for each of the areas or the entire cleaning area based on the created map.

In more detail, the controller 580 maps the area based on the feature points extracted from the image input by the image input unit 550 and the location of the robot cleaner 500 detected by the position detection unit 540. Write each. And, by matching common feature points on the map of the areas adjacent to each other, a map of the entire cleaning area can be created.

When the initial position of the robot cleaner 500 is changed, the controller 580 corrects the created map and controls the operation of the robot cleaner 500 based on the corrected map. The controller 580 controls the operation of the robot cleaner 500 to perform independent cleaning of the entire cleaning area or the area.

The control unit 580 may enter only an area in which the robot cleaner 500 can travel, and may exclude an area that has not entered the cleaning area. Accordingly, the map information of the indoor space may be changed at the current point in time. The changed map information is transmitted to the air purifier (1) (2) and (3), and may be used for driving the air purifier (1, 2, and 3).

17 is a flowchart illustrating a robot cleaner control, and a map correction process is described.

Referring to FIG. 17, first, the driving unit 520 operates and the robot cleaner 500 starts to move (S11). And when the robot cleaner 500 moves, the controller 580 determines whether a map is stored in the storage unit 570, that is, whether a map has been created (S13).

In step S13, if it is determined that the map is stored in the storage unit 570, the image input unit 550 inputs an image (S15). Then, the control unit 580 calculates the location of the robot cleaner 500 on the map (S17).

The calculation of the position of the robot cleaner 500 in the step S17 may be performed by matching the feature points extracted as the image input by the image input unit 550 in the step S15 with the feature points on the map stored in the storage unit 570. have. Therefore, the position of the robot cleaner 500 calculated by the control unit 580 in step S17 may be understood as a position of the robot cleaner 500 on a map.

The position detection unit 540 detects the current position of the robot cleaner 500 (S19). At this time, the position detection unit 540 is the current position of the robot cleaner 500 in consideration of the initial position of the robot cleaner 500 and the amount of movement of the robot cleaner 500 due to the operation of the driving unit 520. Information can be detected.

Here, the initial position is substantially a position after completion of the previous cleaning operation of the robot cleaner 500. For example, a position docked to a docking station (refer to 502 of FIG. 18) for charging or the like after the robot cleaner 500 completes the cleaning operation may be understood as the initial position of the robot cleaner 500 . Accordingly, the position of the robot cleaner 500 detected by the position detector 540 in step S19 may be understood as the actual position of the robot cleaner 500.

The control unit 580 compares the position of the robot cleaner 500 calculated in the step S17 with the current position of the robot cleaner 500 detected in the step S19, and determines whether they match (S21). ). In this case, when the initial position of the robot cleaner 500 is changed, the calculated value in the step S17 and the detected value in the step S19 may be different from each other. That is, when the initial position of the robot cleaner 500 is not changed, the position of the robot cleaner 500 moved by the operation of the driving unit 520 is the position calculated by the controller 580 The positions detected by the position detection unit 540 will match.

However, as shown in FIG. 18, for example, when the position or angle of the docking station 502 docked by the robot cleaner 500 is changed, the initial position of the robot cleaner 500 is substantially Changes. Therefore, in this case, the position (A) of the robot cleaner 500 calculated by the control unit 580 and the current position (B) of the robot cleaner 500 detected by the position detection unit 540 may be different. I can.

18 is a reference diagram for explaining map correction in a robot cleaner.

If it is determined that the calculated value of the position of the robot cleaner 500 and the detected value are different in the step S21, the controller 580 corrects the previously created map (S23). The correction of the map in the step S21 includes the position of the robot cleaner 500 calculated by the control unit 580 in the step S17 and the robot cleaner 500 detected by the position detection unit 540 in the step S19. This can be done by modifying the map data to match the location of ).

For example, as shown in FIG. 18, the control unit 580 may correct a new map M2 by moving the previously created map M1 on a virtual X-Y coordinate.

Next, the controller 580 controls a cleaning operation of the robot cleaner 500 (S25). At this time, when it is determined that the calculated value of the position of the robot cleaner 500 and the detected value match in step S21, the control unit 580 is based on a map stored in the storage unit 570, that is, previously prepared map information. As a result, the cleaning operation of the robot cleaner 500 may be controlled.

When it is determined that the calculated value and the detected value of the position of the robot cleaner 500 are different in the step S21, the controller 580 cleans the robot cleaner 500 based on the map information corrected in the step S23. Control the operation. Accordingly, the robot cleaner 500 may perform a cleaning operation while traveling in the cleaning area. The created map may be stored in the storage unit 570 as current map information.

On the other hand, in the step S13, when the controller 580 determines that map information does not exist, that is, when it is determined that the map has not been created, a map is created (S27) (S29) (S31) (S33). (S35). In more detail, when the image input unit 550 inputs an image, the image processing unit 560 extracts feature points from the image input by the image input unit 550 and stores it in the storage unit 570. Further, the control unit 580 matches the feature points extracted from the current image with the feature points previously stored in the storage unit 570, and the position of the robot cleaner 500 detected by the position detection unit 540 of the robot cleaner 500 Create a map based on. The created map may be stored in the storage unit 570 as current map information.

The current map information may be transmitted to the air purifier (1) (2) (3), preferably the cradle air purifier (1) through the communication unit 590. The cradle air purifier 1 may operate the air purifier according to the embodiment by using the current map information.

The current map information may be directly transmitted to the air purifier (1), (2) and (3) while the robot cleaner (500) performs cleaning. Accordingly, the local map information can be updated more quickly.

The current map information is transmitted to the air purifier (1) (2) (3) after the current map information is obtained, or before the next cleaning is performed by the robot cleaner 500 Can be. According to this, the current map information can always be updated as new information.

In addition to the above-described methods, current map information of an indoor space may be obtained through various methods. In the embodiment, since the latest map information can be updated to the current map information through a simple correction process, the current map information can be obtained more conveniently and quickly.

The current map information may be transmitted to the cradle air purifier 1 whenever the robot cleaner is operated. According to this, it is possible to more accurately identify each area of the indoor space at the present time. For example, a room in a closed state and in which the rolot cleaner cannot enter may be excluded from the current map information. As a result, the air cleaning system according to the embodiment can always perform an optimal air cleaning action at the current point in time.

19 is a diagram showing in detail the system configuration of an air cleaning system according to another embodiment.

Referring to FIG. 19, the configuration of the robot cleaner 500 is shown in FIG. 16. The configuration of the cradle air purifier 1 has been described in detail with reference to FIG. 9. In the description of the present embodiment, a part that is particularly different will be described in detail. In addition, it is assumed that the description is applied as it is to the configuration already described.

In this embodiment, the configuration of the space operation determining unit 420 is characteristically different. Specifically, the space operation determination unit 420 determines an area in which the air purifier (1) (2) (3) at the current time point is placed by referring to the current map information acquired by the robot cleaner (500). I can. This action is to divide a zone in which each air purifier (1) (2) (3) is preferably responsible for the interior of the indoor space, and may be set by the zone division determination unit 421.

Here, since the zone is divided by walls and doors, it can be defined that clean air discharged from a vacuum cleaner placed in one zone cannot directly go to the other zone and cannot reach it. For example, even if the door is not closed, if the direction of the door and the direction of the outlet of the air purifier are different, a different zone can be set.

The space operation determination unit 420 refers to the current map information acquired by the robot cleaner 500, and an installation location where each air purifier (1) (2) (3) is placed within each zone at the current time point. Can be determined. This action is to determine the installation position of each air purifier (1) (2) (3) inside each zone, and can be determined by the air purifier positioning unit (422).

On the other hand, the space operation determination unit 420 can also determine the combined operation and the cooperative operation, as well as the description of the original embodiment may be applied as it is.

In the case of this embodiment, it may be preferably used to determine the position where the cradle air purifier is placed. For example, as a stationary air purifier that does not move, using map information acquired by a robot cleaner in a state where all doors of an indoor space are open, the cradle air purifier can be notified to a user of a desirable location.

FIG. 20 is a reference diagram for explaining the operation of the space operation determination unit 420 as an example, and shows the current map information as information acquired while the robot cleaner 500 travels. In this drawing, there was no closed room.

Referring to FIGS. 19 and 20, according to the current map information, six regions R1 to R6 exist, and it may be determined that each region is open. In this state, the zone division determination unit 421 may determine to place each air purifier by selecting three zones R1 to R3 having a large area and high interoperability with other zones.

The determined arrangement state may be known to the user that the image as shown in FIG. 20 is displayed on the display unit 440 as it is. According to the display state of the display unit 440, the user puts the cradle air purifier 1 in R2, the second tower air purifier 2 in R1, and the first tower air purifier 3 in R3. I can put it.

Correspondence between the zones R1 to R3 and the air purifiers 1, 2, and 3 may be applied to a zone size, connectivity between zones, and weights for each zone. Here, the area size can refer to the area of the area. The connectivity between the zones may mean which one zone is connected to several other zones by a door. The weight for each zone may mean how many other zones the zone is connected to by a wall. The larger the above value, the larger the capacity of the air purifier (1) (2) (3) can be placed.

After the zone division determination unit 421 determines the correspondence between the zones R1 to R3 and the air purifiers 1, 2 and 3, each air purifier 1 ( 2) The installation location of (3) may be set by the air purifier positioning unit 422.

According to the display state of the display unit 440, the user puts the cradle air purifier 1 in R2 at the upper left of R2, the second tower air purifier 2 at R1 at the upper left of R2, and R3 The first tower air purifier (3) can be placed in the upper right corner of R3.

The wind direction can be determined in the diagonal direction of each zone. The wind direction may also be displayed on the display unit 440.

As another situation, in the current map information, any one area, for example R1, may be closed. In this case, the zone division determination unit 421 may determine to place the second tower air purifier 3 on the cradle air purifier 1. Accordingly, the cradle air purifier 1 and the second tower air purifier 3 may be displayed on the display unit 440 as being placed on R2.

In the case of another situation, the air purifier positioning unit 422 may determine to separate the second tower air purifier 3 and the cradle air purifier 1. For example, the second tower air purifier 3 may be placed in the upper right corner of R2, and the cradle air purifier 1 may be placed in the upper left corner of R2, and this determination may be displayed on the display unit 440. . As described above, the air purifier positioning unit 422 may determine where the air purifiers 1, 2, and 3 corresponding to the areas R1 to R3 will be placed inside each area.

In this case, compared to the case where only the zone division determination unit 421 is determined, air flow is promoted, and the entire area of R2 can become an atmosphere of clean air more evenly and quickly.

The zone division determining unit 421 and the process value positioning unit 422 may be displayed on the display unit 440 under the control of the controller.

21 is a diagram illustrating a control method of an air cleaning system according to an embodiment.

When comparing FIG. 21 with the embodiment shown in FIG. 11, first, receiving the current map information from the robot cleaner 500 in the map information acquisition step (S31), and second, in the parent space operation determination step (S32). However, it is different to decide where to place the air purifier inside each divided zone. In addition, the module-specific operation information production step (S33) and the module-specific driving step (S34) are similar to the original embodiment.

Specifically, in the map information acquisition step (S31), the current map information obtained by cleaning and traveling of the robot cleaner 500 may be acquired. Accordingly, it is possible to obtain map information of an indoor space at the current point in time. For example, a closed indoor space may not be included in the current map information. Accordingly, the currently closed indoor space may not be a factor that determines the operating method of the air cleaning system.

In the spatial operation determining step (S32), first, it is determined in which area which air purifier is to be placed, based on the current map information. Here, it has already been described that the correspondence between the zones R1 to R3 and the air purifiers 1, 2, and 3 can be applied to the zone size, the connectivity between zones, and weights for each zone.

Thereafter, in the space operation determining step S32, it is possible to determine where the air purifiers 1, 2, and 3 corresponding to the zones R1 to R3 will be placed inside the zone. For example, in the case of a rectangular area, it may be decided to put air purifiers at two corners of a wall.

The determination of the space operation determining step S32 may be displayed on the display unit and notified to the user.

In a state in which the location is determined in response to the spatial operation determining step S32, at least one of the combined operation and the merge operation may be performed. As for the operation information of the air purifier corresponding to each module, which is performed in the combined operation and the combined operation, the contents as previously described may be similarly applied.

According to the present invention, various air cleaning actions can be performed corresponding to an indoor space by using a single air cleaning system provided with a plurality of air purifiers, and thus industrial applications are highly anticipated.

According to the present invention, an air cleaning system can be operated in response to real-time changes in an indoor space, and in particular, since the best operation method can be proposed, industrial application is greatly expected.
