The air that has passed through the filter member 120 flows upward and is introduced into the fan housing 150 through the fan inlet 152. Air flows in the axial direction of the fan 160 and flows out through the blades 163. In this case, the edge of the blade may extend inclined upwardly outward with respect to the axial direction in correspondence with the flow direction of the air so that the outflowing air may flow upward in the radial direction.

The blowing device 100 may further include an air guide device 170 coupled to an upper side of the fan 160 to guide the flow of air passing through the fan 160. The air guide device ( 170 may be located above the fan housing 150.

5 is a schematic cross-sectional view of the placing frame.

Referring to FIG. 5, in the placing frame 7, a backbone 8 extending upward from the rear end of the first stage air purifier 1 is based on the bottom of the first stage air purifier 1 This includes.

The backbone 8 serves as a frame supporting the load of the first stage air purifier 1 and parts placed on the first stage air purifier 1. The backbone 8 is provided vertically in a bar shape, and a member made of a solid material such as a resin material, a painted iron frame, or wood in which an iron frame is accommodated may be used.

The backbone 8 may be provided with a first lighting 80 fastened in the longitudinal direction of the backbone. The first lighting 80 may irradiate visible light to inform the user of the location of the air cleaning system, inform the operating state of the air cleaning system, or perform a role of a lighting lamp for an indoor space.

At a height slightly higher than that of the first stage air purifier 1, a second stage pedestal 5 supporting the second stage air purifier 2 extends forward from the backbone 8. The second stage pedestal 5 may be fastened or supported on the upper end of the first stage air purifier 1, or may be fastened to the backbone 8. In the drawing, the second stage pedestal 5 is illustrated as being fastened to the backbone 8. In the drawing, the lower surface of the second stage pedestal 5 is in contact with the upper surface of the first stage air purifier 1, and the self-weight of the second stage pedestal 5 and the second stage air purifier 2 is the first However, it is illustrated that it can be supported by the air purifier (1).

The second stage pedestal 5 may have a rectangular bottom surface similar to the cross-sectional shape of the second stage air purifier 2. The second stage pedestal 5 stably guides the seating process of the second stage air purifier 2 and supports the seated second stage air purifier 2, and the second stage air purifier ( It can be provided slightly larger than 2).

The second stage pedestal 5 has a second stage frame 305 provided as a square frame, and an inside or outside of the second stage frame in order to support the load of the second stage frame 305 and the load of the second stage air purifier 2. A two-stage beam 303 placed on it may be included. The second stage frame 305 may evenly support the entire bottom surface of the second stage air purifier 2 and mainly serve to support the load of the second stage air purifier. The two-stage frame 305 is made of a resin, and the second-stage beam 303 is made of a metal material having high strength, so that insufficient strength may be reinforced only with the second frame 305. Stainless steel may be used as the metal material.

Although the two step frame 305 and the two step beam 303 are described as being separate members, they are not limited thereto. As another example, as the same members connected to each other are ejected, the thickness may be changed, or a grid-shaped skeleton may be further provided, and thus the two-stage beam 303 may be provided as an integral type.

On the upper surface of the second step 305, a rail 304 that protrudes upward and extends long in the front-rear direction may be provided. A two-stage connection terminal 301 and a two-stage wireless charging module 302 may be provided on the backbone 8 adjacent to the rear portion of the second stage 305.

The operation of the rail 304, the two-stage connection terminal 301, and the two-stage wireless charging module 302 will be described with reference to other drawings.

6 is a cross-sectional view of the second stage air purifier, and FIG. 7 is a rear perspective view of the second stage air purifier.

6, the second stage air purifier (2) is provided with a height lower than that of the first stage air purifier (1), and its capacity is to be provided smaller than that of the first stage air purifier (1). I can. The function and operation of the second stage air purifier 2 may be provided similarly to the first stage air purifier 1, but the air cleaning capacity may be provided slightly smaller.

A rail seating groove 314 may be provided on a lower surface of the second stage air purifier 2. The rail seating groove 314 may be provided to correspond to the rail 304. Here, the meaning of "correspondence" means that the second stage air purifier 2 is extended in correspondence with each other in the front-rear direction in which it is seated.

Installation positions of the rail 304 and the lane seating groove 314 may be opposite to each other. However, it is preferable that the rail is provided in a form that is recessed from the bottom of the second stage air purifier 2 to the inner surface. This is because when the second stage air purifier 2 is used separately from the placing frame 7, the protruding rail may interfere with the seating of the bottom surface of the second stage air purifier 2.

Referring to FIG. 7, on the rear part of the three two-stage air purifier 2, a two-stage connection part 321 corresponding to the two-stage connection terminal 301, and a second-stage wireless charging module 302. Another wireless charging module 322 is provided.

The second-stage connection terminal 301 and the second-stage connection part 321 may be completely connected to each other by completely mounting the second-stage air purifier 2 on the second-stage pedestal 5. . In other words, when the second stage air purifier 2 is fully inserted along the rail 304, in a state in which the positions of the second stage air purifiers 2 are fully inserted, the operation setting of each other can be completed.

For example, the two-stage connection terminal 301 may be physically wired in a manner that is inserted into the second-stage connection unit 321. Of course, a wireless connection is fine. The two-stage wireless charging module 302 and the other wireless charging module 322 are connected to a signal without physical contact, so that wireless charging can be performed.

By connecting the second-stage connection terminal 301 and the second-stage connection unit 321, the second-stage air purifier 2 may communicate with other components provided in the air cleaning system of the embodiment. . Wired charging may be performed as another example.

The second-stage connection terminal 301 and the second-stage wireless charging module 302 may be provided in other places, such as a rear part of the second-stage pedestal 5, not the backbone. Similarly, the second-stage connection part 321 and another wireless charging module 322 may be provided at corresponding positions of the second-stage air purifier 2.

However, since these parts are provided on the backbone, the connection between the air purifier and the placing frame can be completed while the air purifier is completely positioned on the placing frame during the process of installing the air purifier. In this case, the user can more conveniently recognize the secure positioning and complete connection between the air purifier and the placing frame.

It will be described again with reference to FIG. 5.

The second stage pedestal 5 is as close as possible to the first stage air purifier 1 in the vertical direction, so that the installation space of the air cleaning system can be reduced. By using this, the second stage pedestal 5 may perform a wind direction adjustment function of the discharged wind of the first stage air purifier 1.

The cross section of the two-stage flow path guide 306 on the lower surface of the second stage pedestal 5 increases from the center to the outside and is bent upwardly. The two-stage flow guide 306 may be provided in the same shape in the radial direction.

The second-stage flow guide 306 may serve to change the flow direction of clean air discharged from the first-stage air purifier 1. More precisely, the wind direction of the clean air of the discharged air can be changed from the axial priority to the radial direction. Accordingly, the air discharged from the first stage air purifier 1 is not widespread, and a region in which clean air is first blown can be provided by focusing on the rectilinear side of the first stage air purifier 1.

According to the two-stage flow guide 306, user convenience can be further improved by using the interaction between the integrated air purifiers.

The third stage pedestal 6 is provided at the upper end of the backbone 8.

The roles of the three-stage frame 315 and the three-stage beam 313 provided on the third stage pedestal 6 are similar to those of the second stage frame 305 and the second stage beam 30. However, the edge portion of the three-stage frame 315 may be slightly protruded upward, so that even if there is an external impact while the third-stage air purifier 3 is seated, it may be prevented from falling, shifting or falling.

Hereinafter, the configuration of the third stage pedestal 6 that is different from the second stage pedestal 5 will be described. It is assumed that the same description applies to the same part.

A three-stage fitting stand 314 protruding upward may be provided at a front end of the three-stage frame 315, and a three-stage seating protrusion 317 may be provided at a center portion of the three-stage frame 315. The three-stage fitting stand 314 and the three-stage seating protrusion 317 are for correctly positioning the third-stage air purifier 3 on the three-stage frame 315.

The three-stage fitting table 314 is for allowing a user to grasp the position of the third-stage air purifier 3 placed from the top to the bottom with a guesswork.

It will be described in detail. As an example in which the user uses the air cleaning system according to the embodiment, there is an example in which the third stage air purifier 3 is mounted on the third pedestal 6. In this case, the user stands in front of the air cleaning system and puts down the third stage air purifier 3. Since the user is standing in front of the air cleaning system, the alignment of the air purifier and the pedestal in the left and right directions is well known. However, alignment in the anteroposterior direction is not well confirmed in the field of view.

In this case, it is possible to check the approximate alignment between the devices by using the front end of the third stage air purifier 3 and the third stage fitting table 314.

The three-stage seating protrusion 317 is positioned by fine-aligning the third-stage air purifier (3) in a state in which the base and the air purifier are approximately aligned by the three-stage fitting table 314. I can. By the action of aligning the three-stage seating protrusion 317 and the three-stage fitting unit 314 together, the protruding edge portion of the three-stage frame 315 is seated in a state aligned with the base of the third stage air purifier. Can be.

In this case, a wired or wireless connection between the third stage air purifier 3 and the third stage pedestal 6 can be safely performed.

The two-stage connection terminal 301, and the three-stage wireless charging module 312 performing a similar operation to the two-stage wireless charging module 302, and the operation of the third-stage connection terminal 311 will be described with reference to other drawings do.

8 is a cross-sectional view of the third stage air purifier, and FIG. 9 is a rear perspective view of the air cleaning system in a state in which the third stage air purifier is separated.

8 and 9, a three-stage seating groove 346 is provided in a groove structure corresponding to the three-stage seating protrusion 317. The seating protrusion 317 and the seating groove 346 are configured to be fitted in a shape corresponding to each other. When the seating protrusion 317 and the seating groove 346 are fitted, the third air purifier 3 may not oscillate against an external shock, may fall, or may not fall.

In the three-stage mounting groove 346, another wireless charging module 345 corresponding to the three-stage wireless charging module 312, and a three-stage connection 347 corresponding to the three-stage connection terminal 311 It is prepared. Since the function of each component is the same as that of the second-stage connection terminal 301 and the second-stage wireless charging module 302, detailed descriptions are omitted.

It will be described again with reference to FIG. 5.

A three-stage flow guide 316 similar to the second-stage flow guide 306 may be provided on a lower surface of the third stage pedestal 6. The functions and actions of the two-stage flow guide 306 may be applied to the three-stage flow guide 316 as well. However, by additionally adjusting the distance between the three-stage flow guide 316 and the second-stage air purifier 2, the radial direction and wind speed may be adjusted.

The third stage pedestal 6 may sag by its own weight of the third stage air purifier 3, and the sag phenomenon may be further aggravated by repeated use. This is because the three-stage pedestal 6 is connected only to the backbone 8 to support the entire self-weight. The reason is that the three-stage pedestal 6 is the same as the cantilevered beam supported at one point. In this case, insertion of the second stage air purifier may be hindered. This problem can lead to fatal problems in the use of air cleaning systems.

A configuration corresponding to the sag problem of the pedestal will be described below.

10 is a view briefly showing the relationship between the second stage air purifier and the placing frame into which the second stage air purifier is inserted. In FIG. 10, each line segment can be viewed as connecting the inner surface of each corresponding member, and more precisely, each line segment virtually connects a part that causes interference when the second stage air purifier 2 is inserted. It can be defined as a line segment.

Referring to FIG. 10, a distance H1 of the front portion of the third stage pedestal 6 and the second stage pedestal 5, a clearance H2 of the rear portion of the second stage air purifier 2, and the second stage The front part spacing H3 of the two-stage air purifier 2 may have a relationship of the following equation.

Satisfying at least one condition of

According to Equation 1, the second air purifier 2 may ride the rail 304 and enter the base. To this end, it is preferable that the distance H1 of the front portion of the third stage pedestal 6 and the second stage pedestal 5 is larger than the rear portion clearance H2 of the second stage air purifier 2 . More preferably, even when the third stage pedestal 6 sags, it is preferable that the relationship of H1> H2+5cm is established so that there is no problem in the insertion of the air purifier.

The distance H3 of the front portion of the second stage air purifier 2 may be greater than the distance H2 of the rear portion of the second stage air purifier 2. According to this configuration, even when the gap is reduced due to the sag of the third stage pedestal 6, the second stage air purifier 5 once inserted can be inserted with a gap between the pedestal 5 and 6 have. It can be understood that the second air purifier 2 serves as a wedge.

11 is a front perspective view of the third stage air purifier.

Referring to FIG. 11, a display 503 may be centered on an upper surface of the third stage air purifier 3, and a discharge grill 192 may be provided around the display 503.

A handle 341 is provided on one side of the third stage air purifier 3. The user can conveniently move the third stage air purifier 3 by using the handle 341. Since the third stage air purifier 3 has the smallest capacity, the user will be able to move the third stage air purifier 3 with only his own force without the aid of a separate device.

The handle 341 is fixed to the case by a hinge 342 and is rotatable. When the handle 341 is not in use, it may be placed in a placement groove 343 that is depressed at the upper end of the case 101. Accordingly, it is possible to prevent an external object from being overturned by the handle and the third stage air purifier 3 or the air cleaning system as a whole.

12 is a diagram illustrating the operation of the two-stage flow guide in more detail.

The second-stage flow path guide 306 has been described to change the flow direction of clean air discharged from the first-stage air purifier 1 from axial priority to radial priority. The arrow in FIG. 12 shows the flow of the discharged wind discharged from the first stage air purifier 1. Referring to the arrow, clean air having a relatively large flow rate just before the discharged wind of the first stage air purifier 1 is discharged is gathered together and blown to a specific area.

Since the specific area corresponds to the immediate side of the first stage air purifier, it can be defined as a lateral clean area. The lateral clean area is indicated by a dotted line on the right side of the air purifier.

As described, the air discharged from the first stage air purifier 1 does not spread widely. In particular, it does not spread widely up and down. Accordingly, it is possible to create the lateral clean area in which clean air is first blown by focusing on the immediate side of the first stage air purifier 1.

The diffused clean area contrasted with the lateral clean area is indicated by a dotted line on the left side of the first stage air purifier. The diffusion clean area may mean an area to which clean air discharged from the first stage air purifier 1 reaches when the second stage flow guide 306 is not present. Since the first stage air purifier 1 has a strong axial flow velocity of the discharged wind, it is shown that it spreads more widely in the vertical and horizontal directions.

The lateral clean area may be provided in a space of 50 centimeters or less from the floor used as a playground for children. According to this, it can be more preferably applied when air cleaning is desired intensively with respect to the adjacent position of the air purifier, such as after returning home, when the capacity of the air purifier is insufficient, or when the air purifier is started immediately.

Hereinafter, an operation of an air cleaning system provided with a plurality of air purifiers according to an embodiment will be described. According to the following description, it can be understood that even when the air purifier is separated and assembled, the user can conveniently grasp the state of each component of the air cleaning system and conveniently operate it.

On the other hand, reference numerals used in FIG. 13 may be described by assigning different numbers from the configurations presented above for convenience of understanding. For example, in the above description, numbers 80 to 84 are used, but in FIG. 13, numbers 713 to 716 are used.

13 is a block diagram illustrating a configuration of an air cleaning system according to an embodiment.

Referring to FIG. 13, the air cleaning system according to the embodiment includes first, second, and third stage air purifiers (1, 2, and 3). Here, the first stage air purifier 1 is integrated with the placing frame, so that the placing frame 7 is controlled by the first stage air purifier 1. However, only the control unit of the frame may be configured, and in this case, it may be understood as a control unit of the frame.

The first stage air purifier 1 includes a control unit 701 for controlling the entire system of the device, a memory 703 for storing necessary information, a communication unit 702 for performing communication between devices, and a driving unit.

The driving unit includes a fan motor 704 for inducing an air cleaning action, a first display 705 provided on the mounting frame, a sensor unit 706 for detecting the seating and separation of other air purifiers, and a lighting provided on the mounting frame A device 707, and an air quality sensor 708 may be included.

The sensor unit 706 may be provided with a first Hall sensor 711 for detecting the second stage air purifier 2 and a second Hall sensor 712 for detecting the third stage air purifier 3. .

The lighting device 707 may include first, second, third, and fourth lights 713, 714, 715, and 716, which are provided at each location of the placing frame 7.

In the second and third stage air purifiers 2 and 3, under the control of the controllers 721 and 731, a memory 723 and 732 storing necessary information, and a communication unit 722 for performing communication ( 733) can be provided.

The driving units included in the air purifiers 2 and 3 include fan motors 734 and 724 that perform an air cleaning action, displays 725 and 735 that display a usage state and input a user's instruction, and Air quality sensors 726 and 736 that measure air quality may be included.

In the air cleaning system described above, when the third stage air purifier 3 is mounted, the second hall sensor 712 may detect it. The controller 701 may detect this and change the display mode of the third display 735.

When the positions of the Hall sensor and the magnet are opposite to each other, the third stage air purifier 3 may change the display mode by itself without receiving an instruction from the control unit of the first stage air purifier.

The Hall sensor may be referred to as a first sensing unit, and the magnet may be referred to as a second sensing unit. Any component capable of recognizing that the two sensing units are approached by an interaction between the first sensing unit and the second sensing unit may be applied.

In the display mode displayed on the third display 735, a full mode displaying the driving state of the entire known cleaning system, a magnetic mode displaying the driving state of only the third stage air purifier 3 to which the third display belongs, and air A pollution level display mode that displays the air quality at a location where the clean system is placed, a selection mode that displays the state of the air purifier selected by the user, and a lighting mode that performs a lighting function without displaying information may be included.

In the case of the full mode, the pollution status of the environment in which the air cleaning system is placed can be displayed, or all operating status of each air purifier (1), (2) and (3) can be clearly shown. In the case of the self mode, the third stage air purifier 3 can show the air volume and wind speed of itself.

As an example, when the installation of the third stage air purifier 3 is detected by the second hall sensor 712, the first stage air purifier 1 may display the third display 735 in the full mode. have.

The third display 735 is a part that is most convenient for the user to visualize, and is a part that allows the user to access the air cleaning system and obtain information with high visibility.

The first display 735 may perform an operation incidental to the display operation of the third display 735. For example, an illumination mode or a pollution level display mode may be performed. Of course, in a state in which the third stage air purifier 3 is not mounted on the placing frame, other modes may be performed. However, since the size of the display is small, displayed information may be less.

The display 725 of the second stage air purifier 2 may be covered by the placing frame 7 when mounted. Therefore, it is difficult to perform the full mode. However, when the seating of the second stage air purifier 2 is detected by the first Hall sensor 601, it is natural that the control state of the display can be changed from the self mode to another mode.

The lighting devices 713, 714, 715, and 716 may be displayed in various numbers by following the control of the controller according to the user's selection.

14 is a flowchart illustrating a method of controlling an air cleaning system according to an embodiment. This embodiment will be described on the basis of mounting the second and third stage air purifiers on the placing frame, but it can be understood similarly even when they are separated.

Referring to FIG. 14, a movable movable air purifier is seated on the placing frame 7 (S1). The mobile air purifier may be exemplified by the second and third stage air purifiers 2 and 3.

After the mobile air purifier is seated on the placing frame, the display mode of the mobile air purifier may be changed (S2). As a most representative example, the self mode displaying the operating state of an air purifier equipped with a display may be changed to a full mode displaying the entire state of the air cleaning system. Which mode to change can be stored in memory. Of course, it may be changed to another mode, and the change of the display mode may be predetermined by the user. The mode change can be performed automatically.

It has already been described that the change of the mounting state of the second and third stage air purifiers 2 and 3 can be achieved by the interaction of the Hall sensor and the magnet. Of course, it is not limited thereto, and various other methods may be applied.

Thereafter, if the user selects to change the mode (S3), the user can select a desired mode. For example, the display is provided as a touch panel, and the display mode of the display may be changed according to the number of times the user touches the display. A display mode that can be selected according to a user's selection may include the selection mode, the pollution level display mode, and the lighting mode. Of course, it is not impossible to select the self mode and the full mode.

After that, the display mode desired by the user is displayed (S4).

When the use of the air cleaning system is ended and the second and third-stage air purifiers 2 and 3 are separated from the placing frame 7 (S5), the mode of the display may also be changed (S6). ).

As a representative example, the display performed in the full mode may be changed to the magnetic mode after the air purifier is separated. Switching of this mode can occur automatically to maximize user convenience.

Of course, the user may decide in advance which mode to proceed. A display mode that can be selected according to a user's selection may include the selection mode, the pollution level display mode, and the lighting mode. Of course, it is not impossible to select the self mode and the full mode.

According to an embodiment, a plurality of air purifiers may be used as a group or used separately, or a user may conveniently observe a display and operate an air purification system.

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.
