In FIG. 7, although the configuration is similar to that of the previously described part, other numbers may be assigned for accurate description. For example, the fan 35 of the movable air purifier 2 is referred to as a fan driving unit 46 in this drawing, and includes the fan 35 and has a configuration collectively referring to a power supply unit for driving the fan. Can be used as a name.

Referring to FIG. 7, the air cleaning system according to the embodiment includes a main air purifier 1 and a moving body air purifier 2 that is freely mounted and detached from the main air purifier 1 as described above. .

In the main air purifier 1, a control unit 51 for controlling the device as a whole, a driving unit 55 for performing an operation of the device itself, a memory 52 for storing various information necessary for the operation of the device, and a user's An operation unit 53 into which operation information is input is included.

The sensing unit 59 may include a seating sensor 60 that detects the mounting and detachment state of the moving object air purifier 2, and a dust sensor 61 that detects the degree of contamination of the indoor environment.

A communication unit 54 connected to the control unit 51 may be further provided, and may be connected to an external device to perform communication. For example, the main air purifier 1 and the mobile air purifier 2 may be connected to each other by the communication unit 54. The communication unit 54 is preferably wireless communication, but is not limited thereto and may be wired communication.

The mobile air purifier 2 includes a control unit 41 for controlling the device as a whole, a driving unit 45 for performing an operation of the device itself, a memory 42 for storing various information necessary for the operation of the device, and a user's A manipulation unit 43 into which manipulation information is input may be included.

In the driving unit 45, a fan driving unit 46 for performing an air cleaning function by sucking air from the outside, a display unit 47 for displaying information on operation of the device and indoor environment information, and the moving object air purifier (2) A charging unit 48 may be included to indicate whether or not the charging is in progress and charging progress.

A communication unit 44 connected to the control unit 11 may be further provided to be connected to an external device to perform communication. For example, the communication unit 44 may be connected to the main air purifier 1 and interwork with each other. The communication unit 44 may preferably be wireless communication, but is not limited thereto and may be wired communication.

By communication between the communication units 44 and 54, the operating state of the mobile air purifier 2 may be known as the main air purifier 1. By communication between the communication units 44 and 54, the instruction of the main air purifier 1 may be transmitted to the mobile air purifier 2.

Each operation that can be performed by the air cleaning system will be described.

When the mobile air purifier 2 is seated on the main air purifier 1, the mobile air purifier 2 may be charged by a connection between the charging units 48 and 58.

When the moving object air purifier 2 is separated from the main air purifier 1, the seating sensor 60 detects that the seating state of the moving object air purifier 2 is changed and separated, and can transmit a predetermined signal. have. By using the change of the signal state of the seating sensor 60 as a trigger signal, the control unit 51 of the main air purifier 1 may change the control state of the air cleaning system.

The change in the control state of the air cleaning system by the seating sensor 60 may include a change in the operation state of the main air purifier 1 and a change in the operation state of the lighting unit 62.

The air cleaning system according to the embodiment is characterized in that the moving object air purifier 2 is provided so as to be separated from the main air purifier 1. The movable air purifier 2 may be difficult to provide a high-performance filter due to a narrow internal space. In the mobile air purifier 2, fine dust or the like cannot be completely filtered through the filter, thereby contaminating the surrounding air.

The air cleaning system of the embodiment can eliminate contamination of the peripheral portion due to the action of the moving object air purifier 2. In the control method of the air cleaning system according to the embodiment, the operation of the main air purifier 1 is synchronized with the operation and state of the mobile air purifier 2 in various ways, so that the air cleaning system can prevent contamination of the surrounding area. have.

Hereinafter, various control methods of the air cleaning system will be described.

8 is a flowchart illustrating a method of controlling an air cleaning system according to an embodiment.

8, the moving object air purifier 2 is seated on the main air purifier 1, and at this time, the interlocking between the moving object air purifier 2 and the main air purifier 1 is in a standby state (S1). ). In the standby state, the main air purifier 1 may or may not be in operation.

Later, when the moving object air purifier 2 is separated, the fact can be known to the main air purifier 1 by the seating sensor 60 (S2). The control unit 51 of the main air purifier may operate the driving unit 55 based on the off signal of the seating sensor 60, that is, the separation signal of the moving object air purifier 2 (S3).

When the main air purifier 1 is started together in response to the single operation of the moving object air purifier 2 and the separation of the moving object air purifier 2, the following advantages become clear.

First, the movable air purifier 2 operates in a manner in which dust is sucked rather than blown out. According to this, scattering dust disappears and dust diffuses into the indoor space is reduced.

Second, even if the mobile air purifier 2 filters dust by a suction method, the mobile air purifier 2 is less efficient than the main air purifier 1, so the dust passing through the mobile air purifier 2 There may be. During the movement of the mobile air purifier 2, there may be dust that cannot be sucked into the air purifier and just falls off the clothes. These dusts can pollute the surrounding indoor floor and the surrounding indoor air. The dust in the peripheral portion is sucked and filtered by the operation of the main air purifier 1, so that the dust scattered in the peripheral portion can be further reduced.

Third, the operation of the moving object air purifier 2 and the main air purifier 1 may be interlocked with each other even when there is no user's recognition. According to such automatic interlocking operation, the indoor environment is improved and the user can use the air cleaning system more conveniently.

While the mobile air purifier 2 and the main air purifier 1 are operating together, the mobile air purifier 2 may be mounted on the main air purifier 1 (S4). Mounting of the moving object air purifier 2 may be transmitted to the main air purifier 1 by the seating sensor 60.

After that, the main air purifier 1 may be stopped (S5).

9 is a flowchart illustrating a control method of an air cleaning system according to another embodiment. This embodiment is the same as the embodiment of Fig. 8, and differs only in operating the main air purifier. Therefore, it is assumed that the embodiment of FIG. 8 is applied to parts that are not described in detail.

Referring to Fig. 9, the present embodiment is different from the embodiment of Fig. 8 in that the operation step S3 of the main air purifier is performed after the operation of the moving object air purifier 2 is started. In other words, after both the separation step (S3) of the moving object air purifier and the operation step (S21) of the moving object air purifier are performed, the operation step (S3) of the main air purifier is performed.

At this time, the operation step (S21) of the mobile air purifier may be known to each other between the two air purifiers through the interconnection of the communication units 44 and 54.

According to the present embodiment, in the stage in which the operation of the moving object air purifier 2 is not started, even if the moving object air purifier is separated from the main air purifier, no dust is generated yet. For this reason, it is in a state that the main air purifier 1 may not be operated. According to this embodiment, power consumption can be reduced.

10 is a flowchart illustrating a control method of an air cleaning system according to another embodiment. This embodiment is the same as the embodiment of Figs. 8 and 9, and differs only in operating the main air purifier. Accordingly, it is assumed that the embodiments of FIGS. 8 and 9 are applied to parts without specific description.

Referring to FIG. 10, in the present embodiment, in addition to the embodiment of FIG. 8, even if the moving object air purifier is separated, the main air purifier is not immediately operated. The operation step (S3) of the main air purifier is not only performed after the moving object air purifier is separated from the main air purifier, but also after the main air purifier 1 detects dust. In other words, after both the separation step S3 of the moving object air purifier and the dust detection S22 of the main air purifier are performed, the operation step S3 of the main air purifier may be performed.

The dust detection of the main air purifier may be understood as detecting the amount of dust above a certain level by the dust sensor 61.

Consequently, even if the moving object air purifier is separated, the main air purifier may be prevented from operating if the moving object air purifier does not operate or the dust sensor of the main air purifier does not detect dust above a certain level.

According to the present embodiment, even when the operation of the moving object air purifier 2 is started, the main air purifier 1 is not operated at a stage in which dust is not actually generated. According to this embodiment, power consumption can be further reduced.

11 is a flowchart illustrating a control method of an air cleaning system according to another embodiment. This embodiment is for the convenience of a user who removes dust from clothes, and a configuration for naturally guiding the user to the driving of FIGS. 8 to 10.

Referring to FIG. 11, the mobile air purifier 2 is mounted on the main air purifier 1, and at this time, the interlocking of the mobile air purifier 2 and the main air purifier 1 is in a standby state (S31 ). In the standby state, the main air purifier 1 may or may not be in operation.

Later, when the moving object air purifier 2 is separated, the fact can be known to the main air purifier 1 by the seating sensor 60 (S32). The control unit 51 of the main air purifier may operate the lighting unit 62 based on the detection signal of the seating sensor 60 (S33). The lighting unit 62 may illuminate the clothing. Of course, the user can also conveniently remove dust under lighting.

The lighting unit 62 may correspond to the light 38. In this case, it is possible to conveniently inform the seating position of the moving object air purifier.

The lighting unit 62 may be provided in proximity to a position where the suction unit of the main air purifier 1 is located. In this case, it is convenient because the user can operate the moving object air purifier 2 along the outer surface of the garment to which light is illuminated. Similarly, since the moving object air purifier 2 and the main air purifier 1 are close together, the main air purifier can quickly inhale dust scattered without being sucked from the moving object air purifier. The user can use the mobile air purifier 2 more conveniently and cleanly.

Since the lighting unit 62 is close to the suction unit of the main air purifier 1, the positions of the main air purifier and clothing may be closer. This is because the user will remove dust from the clothing in the vicinity of the lighting unit 62.

Dust that cannot be filtered or scattered by the main air purifier 1 may be sucked into the main air purifier 1. In the end, the floor and indoor space around the air cleaning system can be expected to be cleaner.

While the moving object air purifier 2 and the lighting unit 62 are operated together, the moving object air purifier 2 may be turned off or mounted on the main air purifier 1 (S34). Mounting of the moving body air purifier 2 may be detected by the seating sensor 60 and known to the main air purifier 1.

Thereafter, the main air purifier 1 and the lighting unit 62 may be stopped (S35).

Hereinafter, the operation and configuration of the movable air purifier 2 will be described in more detail. First, a specific request from the mobile air purifier 2 will be described.

The mobile air purifier 2 is a device carried and used by a user, and may be used in direct contact with various clothes. For example, there are cases in which airflow through the surface of clothing is difficult, such as leather goods with a smooth surface or high density fabrics. In contrast, there are cases in which air flow through the surface of the garment is easy with low density, such as knitted fabrics and cotton products. If the moving object air purifier 2 is not operated in accordance with these two cases, the motor may be overloaded or the foreign material may not be sucked due to the excessive clothing and the suction surface being in close contact.

Since the mobile air purifier 2 is carried by the user and is directly in contact with clothes, the user may be inconvenient because a lot of dust is closed on the hand. To this end, by varying the height of the handle 32 and the suction body 31, the handle 32 may be located above the suction body 31. Accordingly, even if the suction body 31 is in contact with the clothes, the handle 32 is higher, so that foreign matter such as dust does not adhere to the user's hand.

The moving body air purifier 2 is small enough to be carried by a user, so it is difficult to mount a large fan motor.

It is difficult to use a high-capacity and high-spec motor for the moving body air purifier 2 due to its narrow internal space. Therefore, it is desirable to be able to prevent failure of the fan motor by strictly controlling the load required for air flow.

The mobile air purifier 2 is a product that the user directly carries, and is preferably operated with low noise in order to reduce consumer dissatisfaction with the noise.

12 is a view showing the air flow inside the suction body.

Referring to FIG. 12, within the suction body 31, a sirocco fan 200 may be placed at a boundary between the discharge port 36 and the suction body 31. The sirocco fan, which is called a multi-wing fan, can be preferably applied because the size of the blower is small compared to the same capacity, and low noise can be obtained.

Compare the sirocco pan and other types of pans.

First, since the axial fan has a large size and is suitable for a wide installation area, it is not suitable for an air purifier for clothes provided with a wide bottom surface as in the embodiment. Also, it is not desirable because it is noisy.

The turpo fan has a problem in that it is difficult to design the air blowing direction in a narrow space. The turbofan is sucked in the axial direction of the motor and discharged radially. To this end, the axial direction of the motor must be installed in the longitudinal direction of the moving object air purifier 1. In this case, the size of the moving object air purifier increases, and there is a concern that turbulence and noise may be severely generated in the air discharged from the turbofan.

Many kinds of other fans, as an improved version of the axial fan and the turbo fan, are difficult to apply. Therefore, in the embodiment, it is possible to preferably use a sirocco fan with low noise and large capacity.

According to the sirocco fan 200, air sucked from the wide suction surface 33 long in the longitudinal direction of the moving body air purifier 2 can be blown toward the discharge port 36. A blocking film 201 is provided on the discharge side of the sirocco fan to prevent the discharged air from flowing backward.

The suction side of the sirocco fan 200 is opened in the width direction of the suction body 31, so that air can be sucked in a wider area. Air can be sucked from both intake ports of the sirocco fan, and a larger amount of air can be sucked. In this way, the air introduced from the suction body 31 is introduced into the suction side of the wide sirocco fan and can be operated with low noise. Sirocco fan's ventilation method is low noise, so the noise can be further lowered.

Since the discharge side of the sirocco fan is aligned to face the discharge port 36, and the discharged wind can be directly guided to the discharge port 36, it can be operated with more low noise. In addition, it is possible to perform large-capacity blowing in the same installation space, and to reduce the size by utilizing the internal space of the moving object air purifier. Therefore, it can be more preferably applied to the small size of the moving body air purifier (2).

13 is a bottom view of the mobile air purifier, and FIG. 14 is a cross-sectional view of a portion of the suction surface.

13 and 14, looking at the suction surface 33 in more detail, the suction surface 33 may be provided in two layers. Specifically, in the two layers, a first suction surface 331 having a plurality of slits 332 which is placed on the lower side and air is sucked from the outside, and a first suction surface 331 having a protrusion 312 passing through the slit 332 It may have 2 suction surfaces 340.

Here, the first suction surface 331 and the second suction surface 340 are frame structures that are aligned up and down to smoothly guide the suction flow of air and perform respective actions. For this reason, the first suction surface 331 may be referred to as a lower frame in other words, and the second suction surface 340 may be referred to as an upper frame. However, for convenience of understanding, the names are referred to as the first suction surface 331 and the second suction surface 340, and will be described as a configuration constituting the suction surface 33.

The slit 332 may extend in one direction, and the protrusion 312 may also be provided in a long shape extending in one direction. Accordingly, dust can be removed more quickly by using the action of the moving object air purifier that the user holds, sweeps, and moves.

The second suction surface 340 may move up and down by a vertically lifting structure. Accordingly, the protrusion 312 may pass through the slit 332 and go further downward, or may enter into the slit 332.

The end of the protrusion 312 may go further downward beyond the slit 332. In this case, the end of the protrusion 312 pushes the garment so that a gap may be created between the first suction surface 331 and the garment. In this case, a space is created between the clothing and the first suction surface 331 so that air can flow in more smoothly. It can be preferably applied when air flow through the surface is difficult, such as leather products.

An end of the protrusion 312 may enter the upper side of the slit 332. In this case, the first suction surface 331 and the surface of the garment may contact each other. At this time, the protrusion 312 exits from the gap between the slits 332 and the flow resistance of air passing through the gap between the inner surface of the slit 332 and the protrusion 312 may be reduced. This case can be applied when the air flow is smooth, such as a knitted fabric. At this time, since the air flow through the knitted fabric is smooth, there is no need to consider the difficulty of air flow due to contact between the clothing and the first suction surface 331.

An optical sensor 310 for measuring foreign substances may be provided where the air sucked from the suction body 31 flows. The optical sensor 310 may include a light emitting unit 303 emitting light and a light receiving unit 304 receiving light emitted from the light emitting unit 303. By grasping the degree to which light emitted by the light emitting unit 303 is received by the light receiving unit 304, the amount of foreign substances such as dust contained in the inhaled air may be determined.

It is possible to control the driving speed of the fan motor according to the amount of the foreign matter identified. For example, if there is a lot of dust, it is possible to automatically increase the driving speed of the fan motor.

In addition to the slit 332, a plurality of holes 302 through which air passes may be provided on the first suction surface 331. External air can always be introduced through the hole 302. Therefore, foreign matter can be removed regardless of the type of clothing.

As a result, a path through which air is sucked through the first suction surface 331 may be provided in two places, the slit 332 and the hole 302. The slit 332 is in a state in which there is resistance to air intake by the protrusion 312, and the hole 302 is always open, so that air can always be inhaled except for resistance due to contact of clothing. have. According to this structure, irrespective of the type of clothing, there is no difficulty in inhaling air and sufficient air can be inhaled. Therefore, it is possible to prevent overload of the fan motor.

Hereinafter, the operation of the mobile air purifier will be described with reference to a block diagram. In the following description, the configuration is the same as or similar to the previously described parts, but for convenience of understanding, separate reference numerals are given for explanation. For example, in the previously described part, the fan motor is referred to as 35, but in the description of FIG. 15, the fan motor is referred to as 401.

15 is a block diagram illustrating the operation of the moving object air purifier according to the embodiment.

Referring to FIG. 15, a controller 400 for controlling the moving object air purifier as a whole, and a memory 405 for storing information necessary for the operation of the controller 400 are included. A driving unit driven under the control of the control unit 400 includes a fan motor 401 that generates air flow of the moving object air purifier, an optical sensor 402 capable of grasping the amount of foreign substances such as dust, and the fan motor ( A motor load sensor 403 capable of grasping the load of the 401, and a second suction surface controller 404 for raising and lowering the second suction surface 340 may be included.

The fan motor 402 may be a sirocco fan and a motor driving the sirocco fan. The optical sensor 402 has illustrated a sensor structure provided as a pair of light emitting units and light receiving units. Of course, the present invention is not limited thereto, and various types of sensors previously provided may be used.

As the motor load sensor 403, a sensor for measuring the rotational speed of the fan motor compared to the input power of the motor, measuring the amount of heat generated by the fan motor, or measuring the back electromotive force of the fan motor may be used.

The second suction surface controller 404 may illustrate a structure of a rack, a pinion, and a motor, and may exemplify a structure for raising and lowering the second suction surface 340 under control of the controller 400.

The operation of the mobile air purifier will be described.

When the operation of the moving object air purifier is started, the moving object air purifier may be operated at a driving speed of the fan motor 401 and a height of the second suction surface 340 selected by the user or set in advance.

Thereafter, the amount of the foreign matter may be detected by the optical sensor, and the degree of the sensed foreign matter may be used as the degree of contamination of the clothing, and the driving speed of the fan motor 401 may be adjusted.

When there are many foreign substances, the driving speed of the fan motor 401 is increased, so that foreign substances from clothes can be quickly sucked. In particular, in this case, it is possible to quickly inhale foreign substances scattered from the mobile air purifier and clothing by using a strong air flow rate. Accordingly, it is possible to reduce the dust scattering around the air purifier of the moving object. In this case, the noise may be relatively loud, but it may be desirable in terms of efficiency and hygiene.

If there are few foreign substances, it can be operated in reverse.

By performing such an operation, it is possible to automatically operate the moving object air purifier according to the amount of dust.

On the other hand, while the operation of the moving object air purifier is in progress, the type of clothing can be grasped using the motor load sensor 403.

For example, when the clothing is a leather product, when the first suction surface 331 and the surface of the clothing come into contact with each other, the flow resistance of air is high. In this case, due to the large load of the fan motor detected by the motor load sensor 403, it can be recognized that the product is leather.

In this case, by controlling the second suction surface controller 404, the protrusion 312 may be further lowered. The protrusion 312 may push the clothing so that the clothing and the first suction surface 331 are not in close contact with each other but are separated from each other by force. Eventually, air can flow in more smoothly.

When air flow is free, such as a knitted fabric, the flow resistance of air is not large. In this case, by controlling the second suction surface controller 404, the protrusion 312 may be moved upward. As a result, the air flow resistance of the spaced portion between the protrusion 312 and the slit 332 may be reduced, and air may be sucked more smoothly.

In this case, since the knitted fabric has a sparse structure, the flow of air through the knitted fabric may be smooth. Therefore, even if the knitted fabric and the first suction surface 331 come into contact with each other, it is fine.

By such an operation, it is possible to automatically remove foreign substances from the clothing based on the material of the clothing.

The air cleaning system of the present invention is provided with a main air purifier having a fixed position, and a moving body air purifier that is freely mounted on the main air purifier and freely applied to clothes.

According to the present invention, not only can the two devices be used individually, but also dust cleaning of clothes can be performed with higher efficiency by mutual cooperation between the two devices, and thus industrial application is greatly expected.

According to the present invention, the user can use the mobile air purifier more conveniently and cleanly.
