It is to be understood that the presence or addition of elements or numbers, steps, actions, components, parts, or combinations thereof does not preclude in advance.

1 is a view showing a wall-shaped frame of the smart wall 100. The present invention relates to a smart wall 100 in which electronic devices used at home, such as media devices and home appliances, are integrated on a wall so that they are not exposed to the exterior. Various electronic devices such as display unit, interphone, speaker, air purifier, humidifier, lighting, digital clock, router, and set-top box are mounted on the wall to provide a total space solution that minimizes the exposure of electronic devices in the space.

Recently, as the thickness of the display device 161 has become thinner, the thickness of the smart wall 100 can be formed to be as thin as 15 to 20 cm, so that the indoor space can be prevented from being narrowed during installation. Rather, storage furniture and home appliances 160 may be embedded in the smart wall 100 to provide a neat appearance. If necessary, a part of the wall may be selectively drawn out so that the necessary home appliance may protrude, and the space where the home appliance is not buried may be utilized as a mounting space 114 such as a drawer.

A TV can be made thinner in recent years, and thus a thin display unit can be implemented. In reality, the TV itself serves as a cover for the frame and can be combined with the frame to form a front appearance. An opening 153 may be formed in the art wall 151 to expose the display portion of the display device 161, and a cover for opening and closing the opening 153 may be further provided.

Since the display unit using OLED is bent, it is exposed to the outside only when in use, and when not in use, it can be rolled up and stored inside the wall, thus providing a neat screen in appearance.

As for the projector, a short throw projector was recently developed, and a large screen can be realized by mounting the projector on a wall, drawing it out in a drawer format, and outputting it to the screen. In this case, when not in use, the display unit is not visible on the outside of the smart wall 100 so that a cleaner appearance can be provided.

2 is an exploded view of the smart wall 100, the interior of the front art wall 150 may be a structure of a frame in which a plurality of shape steel 115 (shape steel) is arranged in a grid. The frame structure 110 is a rigid member and can be supported so as not to collapse even when an impact is applied to the wall. A panel may be attached to the front of the frame structure 110 to hide the electronic product 160 mounted on the frame structure 110 and be configured to appear as a wall. The front wall covered with such a panel is referred to as an art wall 150.

The art wall 150 can be changed differently according to a consumer's taste. After installation, you can easily change it to change the atmosphere of your home.

The section steel 115 arranged in a grid form may partition the mounting space 114 and mount the electronic product 160 in each mounting space 114. Each of the mounting spaces 114 may have the same size or multiple sizes, so that the mounted electronic product 160 may be modularized and disposed at any position in the frame structure 110.

In addition to the above-described display device 161, a sound device 152 such as a speaker 162 may be mounted in the mounting space 114, and a plurality of sound devices 152 may be configured according to the number of channels. The art wall 152 covering the sound device may be configured in a mesh shape so that sound can be output, or an opening that is exposed to the outside may be minimized by selectively opening and closing an opening through which sound is output. For waterproofing, the opening may be prevented from inflow of water by using a waterproof mesh or the like.

Seasonal appliances such as a dehumidifier 163, a humidifier 165, an air conditioner, and a stove may be provided. Such seasonal home appliances are generally exposed to the outside when they are not in use, and dust accumulates and looks bad, so it is common to put a cover on it or put it in a warehouse. However, if it is embedded and installed in the smart wall 100 as in the present invention, it can be used when necessary, and when not used, it can be covered with the art wall 150 so that it is not exposed to the outside, and a separate mounting space 114 is provided. no need.

The dehumidifier 163 or the humidifier 165 may implement a drawer-type space for collecting/storing water to remove collected water or fill water. An opening 154 through which air passes in order to discharge water or collect moisture around it is required. The air purifier can be installed on the lower part of the smart wall 100 so that the user can easily open the filter so that the filter can be replaced periodically.

Even if these openings 154 are not necessarily formed in the art wall 150, the gap between the art wall 150 and the frame structure 110 may be used.

In addition, if a set-top box or WIFI router is installed, it can be implemented as a home network system. Through the WIFI router, not only the functional units mounted on the smart wall 100 but also other electronic devices such as a computer or a portable terminal located outside the smart wall 100 can be connected and controlled by interworking with each other.

An LED or a small display panel can be arranged on the top to provide simple information such as weather and time event information to the user, or can be used as lighting. By arranging lighting on the smart wall 100 itself, it is possible to add an interior effect.

A router is an intermediate device that, when using different communication methods or signals, organizes and guides the router. In addition, the functional unit mounted on the smart wall 100 may not necessarily be connected by wire, but may be connected and controlled through a WIFI router.

In addition, since the router plays a role of connecting the external network and the internal network at the same time, the user controls the router connected to the external network from the outside to control not only the functional units mounted on the smart wall 100 but also home appliances and media devices connected to the internal network can do

In addition, electronic devices of the smart wall 100 may be controlled by interlocking with a mobile device. That is, when a mobile device is mounted on the smart wall 100, media images and music in the mobile device are output, or when a video call is received through the mobile device, the other party's image can be provided through the display of the smart wall 100. have.

In addition, a wall pad connected to a camera or method system at the entrance may be provided in the mounting space 114 of the smart wall 100. Wall pads that were buried in the existing bearing wall were difficult to repair and replace in case of failure, and difficult to change their location. However, if the wall pad is configured in a unit form and provided in the smart wall 100, there is an advantage in that maintenance is easy.

The smart wall 100 can be installed not only in the living room but also in the room. By configuring the walls between the rooms as the smart wall 100, the smart wall 100 may be used in both directions in neighboring rooms. For example, if one air conditioner or air purifier is passed in both directions, it can be used in both spaces. Instead of the TV and speaker 162 used in the living room, a monitor and a PC may be mounted and used according to the purpose of the room. Alternatively, other functional units such as an electronic blackboard may be mounted and used according to the age of the child.

When installed in an office, a smart wall 100 equipped with a functional unit such as an electronic blackboard, an air purifier, a video conference system, and a PC can be used. Since the electronic product 160 mounted on the smart wall 100 is covered by the art wall 150, a separate exterior case is not required.

If the smart wall 100 is manufactured according to the user's installation location at the factory and then installed, the same module can be manufactured and supplied on a large scale when constructing a hotel/resort or apartment, reducing the defect rate and producing it at low cost.

However, the assembled smart wall 100 is difficult to transport, and when the building is completed, it is difficult to carry it into the building. Accordingly, when the smart wall 100 is installed when moving or interior in an existing building, the smart wall 100 may be implemented by installing a frame in the building and inserting a unit module. In this case, for convenience and standardization of installation, the frame structure 110 may be implemented using a plurality of module frames.

3 illustrates a method of combining

frame modules

111, 112, and 113 of the smart wall 100 according to an embodiment. In order to mount each component,

frame modules

111, 112, and 113 in the form of a bookshelf including a mounting space 114 may be used.

Frame modules

111, 112, and 113 may be manufactured by arranging a plurality of beam-shaped members in a grid to partition the mounting space 114.

The

frame modules

111, 112, 113 are a first frame module 111 in which the mounting spaces 114 are arranged side by side in a horizontal direction, and a second frame module for mounting a large product 160 such as a display device 161 It may include a third frame module 113 in which 112 and the mounting space 114 are arranged side by side in the vertical direction.

The second frame module 112 includes a large space so that all of the display devices 161 can be mounted regardless of the inch. If necessary, as shown in FIG. 4, the display device 161 may be fixed by providing a beam that partitions the mounting space 114 and the rigidity of the frame structure 110 may be improved.

The first frame module 111 may be stacked and disposed in a vertical direction with the second frame module 112. The length of the first frame module 111 in the horizontal direction may be the same as the length of the second frame module 112 in the horizontal direction, so that the grid may not be displaced when stacked in the vertical direction.

The first frame module 111 may be disposed on the upper side and the lower side of the second frame module 112, respectively, and according to the size of the first frame module 111 and the second frame module 112 or the size of the installation space. Accordingly, the number of stacked first frame modules 111 in the vertical direction may be increased or decreased.

The third frame module 113 in which the mounting spaces 114 are arranged in the vertical direction may have the same height as the first frame module 111 and the second frame module 112 stacked in the vertical direction. The third frame module 113 may be located in the lateral direction of the first frame module 111 and the second frame module 112 as shown in FIG. 4. A plurality of

frame modules

111, 112, 113 may be combined with fasteners to form a rectangular parallelepiped frame structure 110.

4 is a diagram illustrating a method of manufacturing the

frame modules

111, 112, and 113, and a third frame module 113 in which the mounting space 114 is disposed in a vertical direction will be described as an example. Each of the

frame modules

111, 112, and 113 may use a section steel 115 that is elongated in one direction. Shape steel is a structural member and collectively refers to a rod-shaped member having various cross-sectional shapes. It is possible to construct a column-shaped section steel having the same cross-section in the longitudinal direction by rolling or bending the plate. Section steel has an advantage of being able to obtain rigidity of a certain size or more with lighter and less material since there is an empty space than a beam-shaped member having a circular or square cross section.

The present invention may use a C-beam 115 having a C-shaped cross section as shown in FIG. 4. The C-beam 115 may be formed by vertically bending both ends of a metal plate in the width direction. If both ends are vertically bent only once, they have a C-shaped cross-section, and if they are vertically bent twice, they can have a C-shaped cross-section. In the internal space, a power or signal line connected to the electronic product 160 may be disposed, and an outlet module 140 to which power or data cables are fastened may be disposed.

The outlet module 140 may include a power terminal for supplying power, a data terminal for transmitting and receiving data such as an Internet line or cable input, and a connector for connecting a functional unit inserted in the frame with another functional unit. The connector has terminals on both sides of the frame, and data can be exchanged with each other by inserting a data connection line of each electronic device into the terminal. The outlet module 140 may include a rail structure that moves along the

frame modules

111, 112, and 113.

A vent hole 116 may be formed in the section steel 115 as shown in FIG. 4. The vent hole 116 may reduce the weight of the section steel 115 and discharge heat generated from the electronic product 160. In order to dissipate heat more actively, a fan can be used to discharge hot air to the outside. When the heat of the electronic product 160 is discharged indoors, a heating effect may be obtained in winter. However, in summer, a structure that discharges heat to the outside can be added by circulating heat inside by using a fan as a cause of increasing the indoor temperature, or by adding to the wiring connected to the outdoor unit of the air conditioner.

Each

frame module

111, 112, 113 may include an outer cavity forming a square around the outer circumference and an inner cavity for partitioning the mounting space 114 therebetween. The outer steel may include a vertical steel extending in a vertical direction and a horizontal steel extending in a horizontal direction. The first frame module 111 to the third frame module 113 may be assembled by arranging a horizontal steel between a pair of vertical steels. In order to fasten the vertical steel with the fixing member 120 fixed to the ceiling and the floor, it is necessary to arrange the upper and lower ends of the vertical steel to be exposed. Therefore, by placing the vertical steel outside the horizontal steel, it is possible to insert and fasten the

vertical brackets

122 and 123 of the fixing member 120 to the end of the vertical steel.

The inner steel located inside the outer steel divides the space surrounded by the outer steel to form the mounting space 114, and the inner steel may be assembled so that it cannot be moved by welding to the outer steel, and some inner steels can be assembled using bolts or hooks. They can be combined so that they can be removed as needed.

In this way, by using a method of fastening between the

frame modules

111, 112, and 113 in the form of the semi-finished product 160, the number of assembly at the site can be minimized. The dimensions of the product 160 can be kept constant and installation time can be reduced. In addition, because it can be modularized into a size that is easy to move, it can be easily transported to the site.

5 shows examples of various frame structures 110 according to a combination of

frame modules

111, 112, and 113. FIG. 5A is a frame structure 110 in which a pair of first frame modules 111a, one second frame module 112a, and a pair of third frame modules 113 of FIG. 3 are assembled. ). Since the first frame module 111a has four mounting spaces 114, it may be difficult to install in a narrow indoor space due to its wider width.

Accordingly, as shown in FIG. 5B, a first frame module 111b having a short horizontal length including three mounting spaces 114 may be used. The second frame module 112b may have a length corresponding to the horizontal length of the first frame module 111b.

In addition, the third frame module 113 may be disposed on both sides of the first frame module 111 and the second frame module 112 vertically stacked. Since the floor height of a typical house is 220cm ~ 230cm, the height of the third frame module 113 may be configured to be a little less than 220cm. Although a five-stage vertical frame is shown in the drawing, a six-stage vertical frame may also be manufactured in preparation for a case of a double layer or a high floor height.

When installing in a narrower space, the third frame module 113 may be omitted and the frame structure 110 may be constructed using only the first frame module 111a and the second frame module 112a, or a large display device ( If 161 is not mounted, the frame structure 110 may be implemented by arranging only the third frame in a line. Each

frame module

111, 112, 113 may be fastened with bolts or may be fastened by a welding method.

6 is a view for explaining a method of installing the frame structure 110 of the smart wall 100 according to an embodiment. The frame structure 110 configured by fastening the

frame modules

111, 112, and 113 may be fixed to the ceiling and the floor for installation in an indoor space.

The fixing bracket 125 installed on the ceiling or floor is a member that is bent in an L-shape, and one side 125b extends in a vertical direction from the ceiling or floor and the other side 125a from the ceiling or floor. It may include a first vertical bracket 122 inserted into the inner space of the vertical cavity of the first frame module 111 and the second frame module 112.

The first vertical bracket 122 may be formed to be longer than the vertical length of the first frame module 111 so as to fasten not only the first frame module 111 but also the second frame module 112. A second vertical bracket 123 disposed parallel to the first vertical bracket 122 and inserted into the third frame module 113 may be further included. Since the vertical steel of the third frame module 113 is one member, it does not need to be as long as the first vertical bracket 122.

The coupling bracket 121 coupled to the ends of the first vertical bracket 122 and the second vertical bracket 123 may form a T-shape together with the

vertical brackets

122 and 123. The coupling bracket 121 is coupled to the

vertical brackets

122 and 123, and is vertical from the seating portion 121b and the seating portion 121b that are seated on the upper surfaces of the first frame module 111 and the third frame module 113. It may include a fastening portion 121a extending in the direction and fastened with the fixing bracket 125. The coupling bracket 121 and the fixing bracket 125 can be fastened using a screw, and the fastener to which the screw is fastened may be formed to be long in the vertical direction so that it can be adjusted according to the ceiling height.

When the smart wall 100 is installed over an existing wall, it may further include a fixing member 120 fastened to the existing wall.

Since the smart wall 100 has an audio device, such as the speaker 162, when it is used as a temporary wall, a space separated from the wall is generated. At this time, in order to block the sound of the two spaces, the smart wall 100 may be fixed by adding a soundproof structure so that sound does not leak to the ceiling, floor, and sidewalls in contact with the smart wall 100.

7 is a view for explaining the basket 130 of the smart wall 100 according to an embodiment. The

frame modules

111, 112, and 113 may be divided into a plurality of mounting spaces 114 by using the inner section steel 115. As shown in FIG. 7, a space in which the electronic product 160 is mounted may be provided by inserting the basket 130 into the mounting space 114. The second frame module 112 has a relatively large mounting space 114 because the display device 161 is located, but the mounting space 114 of the first frame module 111 and the third frame module 113 is It can be formed in a standardized size. If the mounting space 114 of a standardized size is used, the basket 130 can also be standardized, and thus there is an advantage in that there is no need to manufacture parts having various shapes unnecessarily.

If the size of the mounting spaces are all the same, it is convenient for standardization, but a larger space may be required depending on the electronic product 160 to be mounted. For example, since the sizes of the air conditioner and the air purifier are different, the size of the mounting space 114 may be formed to be an integer multiple of the basic size in consideration of this difference. For example, a second mounting space 1142 having a horizontal size of an integer multiple of a based on the first mounting space 1141 having a horizontal size of a and a vertical size of b, or a third having a vertical size of an integer multiple of b It may include a mounting space (1143).

The size of the first mounting space 1141 in the horizontal direction corresponds to the size of the third frame module 113 in the horizontal direction, and the size in the vertical direction corresponds to the size of the first frame module 111 in the vertical direction. Here, the mounting space 114 means an internal space divided by the section steel 115, so the comparison between the size of the first frame module 111 and the size of the third frame module 113 is the difference due to the thickness of the section steel 115 Is ignored.

Since the first frame module 111 has a short length in the vertical direction, it may include only the first mounting space 1141 and the second mounting space 1142, and the third frame module 113 has a short length in the horizontal direction. Therefore, only the first mounting space 1141 and the third mounting space 1143 may be included.

8 is a perspective view showing an example of an air purifier 164 according to an embodiment. The air purifier 164 may be disposed in one of the mounting spaces 114 of the frame structure 110, and the basket 130 may be omitted by forming the outer case in a size suitable for the size of the mounting space 114 .

The air purifier 164 has

openings

16461a and 16461b through which the air purified by the air purifier 164 is discharged in the art wall 150 on the front so that the air can be sucked in to remove impurities and discharge the air again. The

openings

16461a and 16461b may be opened or closed or may be selectively exposed. The air purifier 164 may be located under the display device 161,

The smart wall 100 may be additionally installed on a wall, but as shown in (a) of FIG. 8, itself may serve as a wall that divides the indoor space. In this case, the

openings

16461a and 16461b may be formed on both

sides

150a and 150b of the smart wall 100, and the purified air discharged from the air purifier 164 is 2 Can be provided in the space of the dog. Figure 8 (a) is a first outlet (16461a) facing the living room (1st room, room 1), Figure 8 (b) is a second outlet (16461b) facing the back room (2nd room, room 2). . The positions and sizes of the first outlet 16461a and the second outlet 16461b need not necessarily be the same, and a plurality of air purifiers 164 may be mounted in the smart wall 100.

9 is a view showing a cross-section of the air purifier 164 according to an embodiment. The air purifier 164 includes a body 1641 and a filter 1643 and a blower fan 1644 positioned inside the body 1641. The blowing fan 1644 is a device that sucks air so that outside air passes through the air purifier 164, and a filter 1643 is placed between the blowing fan 1644 and the inlet, so that the air purifier 164 in the filter 1643 It can purify the air entering the interior. The blowing fan 1644 may introduce air from the front side and discharge the air from the side, as shown in FIG. 9. The blowing fan 1644 may change the direction of air flowing into the air purifier 164 and discharge it, thereby increasing the utilization of the internal space of the air purifier 164.

The air that has passed through the blowing fan 1644 is discharged to the outside again through the outlets 16416a and 16461b. The air purifier 164 is mounted on the smart wall 100 located between the first room (room 1) and the second room (room 2). Purified air can be supplied at the same time.

An exhaust chamber 1646 for distributing the purified air to the two spaces may be further included. 10 is a view showing the exhaust chamber 1646 of the air purifier 164 according to an embodiment, the exhaust chamber 1646 includes a plurality of outlets 1646 facing one side and the other side of the smart wall 100 can do. In order to minimize the number of members exposed on the art wall 150a, the first outlet 16461a may be disposed in a direction that is difficult to see from the front. As illustrated in FIG. 10, the first discharge port 16461a may be disposed under the display device 161 so that the discharge port faces upward.

The second outlet 16461b in the direction of the room 2 is not disposed so that the display device 161, etc. is disposed, so it is difficult to arrange it so that it is not visible to the user, like the first outlet 16461a, it is perpendicular to the art wall 150b. A second outlet 16461b may be formed in the direction. In addition, the heights of the first outlet 16461a and the second outlet 16461b may be different according to the situation of the space.

The exhaust chamber 1646 may include a partition plate 16463 so that air is distributed and discharged to the first outlet 16461a and the second outlet 16461b. The amount of air moving to the first outlet 16461a and the second outlet 16461b may be adjusted according to the position of the partition plate 16463. In general, since the size of the living room (room1) is larger than the size of the master (room2), the partition plate 16463 may be arranged to be skewed from the center to the second room (room 2) so that more air moves to the living room. When the side facing the living room of the smart wall 100 is referred to as the front side and the side facing the back side is referred to as the rear side, the partition plate 16463 may be arranged to be skewed toward the rear side.

A connection body 1645 may be further included to seal between the exhaust chamber 1646 and the body 1641. The connecting body 1645 protrudes from the discharge port of the body 1641 and is in close contact with the exhaust chamber, and the connecting body 1645 seals the space between the exhaust chamber 1646 and the body 1641 so that the air has passed through the air purifier 164. May be discharged through the first discharge port 16461a and the second discharge port 16461b without leaking in the middle.

When the user inserts the air purifier 164 into the mounting space of the frame structure using the lever 1647 and the pressure protrusion 1648, the pressure protrusion 1648 pushes the lever 1647, and the connecting body 1645 is the exhaust chamber. By moving toward 1645, the space between the exhaust chamber 1646 and the body 1641 may be connected.

When air is supplied to two spaces using one air purifier 164, air must be supplied by appropriately distributing it to the two spaces. First, the amount of air discharged through the first discharge port 16461a and the amount of air discharged through the second discharge port 16461b must be sensed. According to the present invention, the amount of air discharged to each of the outlets may be sensed by disposing the air volume detector 210 at the first outlet 16461a and the second outlet 16461b, respectively.

The air volume detector 210 is a device that measures the amount of air discharged through the first outlet 16461a and the second outlet 16461b. Even though the positions of the first outlet 16461a and the second outlet 16461b are different as shown in FIG. 9, the air volume sensing unit disposed in the first outlet 16461a, the air volume sensing unit 210 and the second outlet 16461b ( The position of 210 may be the same from the blowing fan 1644. It is preferable that the distance from the blowing fan 1644 is the same in order to accurately compare the amount of air exiting the first outlet 16461a and the second outlet 16461b.

FIG. 11 is a diagram illustrating an air volume sensing unit 210 of an air purifier 164 according to an exemplary embodiment, and FIG. 12 is a diagram illustrating a method of measuring an air volume using the air volume sensing unit 210 of FIG. 11 to be.

The air volume sensing unit 210 of this embodiment includes a rotating fan 212, a magnet 213, and a hall sensor 214. The rotating fan 212 rotates when air passes through the rotating fan 212, and rotates faster when the amount of air passing through it is large. The rotating fan 212 includes a plurality of blades extending radially from the rotation center, and the blades may be formed in a streamlined shape curved in one direction as shown in FIG. 11(b), and as the amount of air passing through it increases, the rotating fan 212 Can rotate faster.

In order to accelerate the flow of air through the rotating fan 212, an inclined guide 211 having an outlet narrower than an inlet may be further included. As the air passing through the blowing fan 1644 passes through the inclined guide 211 having a narrow outlet, the speed is accelerated, so that the rotating fan 212 can be rotated with a greater force.

The inclined guide 211 may further include a rib 215 having a curved surface that is bent in the same direction as the direction in which air is bent in accordance with the rotation direction of the rotation fan 212 so that air can pass therethrough. When the air moves along the rib 215 in a spiral manner, the rotation fan 212 may rotate faster.

In order to fix the rotating fan 212 to the exit of the inclined guide 211 so as to be rotatable, the rotating fan 212 includes a bridge crossing the exit as shown in FIG. 11, and the rotation center is pin-coupled to the bridge. It can be rotated. Air may move to the space 211a other than the bridge and exit through the

outlets

16461a and 16461b.

In order to detect the rotation cycle of the rotating fan 212, a magnet 213 located on the rotating fan 212 and a hall sensor 214 for detecting the magnet 213 may be disposed adjacent to the magnet 213. have. The Hall sensor 214 is a device that detects the magnetism of the magnet 213, and when the magnet 213 is positioned closer to the Hall sensor 214 by a predetermined distance or more, the Hall sensor 214 may generate a signal.

When the magnet 213 is arranged to be offset from the rotation center of the rotation fan 212 in one direction, the distance from the hall sensor 214 changes periodically when the rotation fan 212 rotates. In the state shown in (a) of FIG. 12, the Hall sensor 214 generates a signal, and in the state of (b) of FIG. 12, the Hall sensor 214 does not generate a signal. You can get it. If the period in which the Hall sensor 214 generates a signal is short, it may be determined that the speed of the rotating fan 212 is high and the amount of air passing through the corresponding air volume sensor 210 is large.

In addition to the magnet and the Hall sensor, a sensor capable of detecting the rotation period of the rotating fan 210 may be applied. For example, it is possible to calculate the number of revolutions by detecting the blade portion of the rotating fan 210 using a proximity sensor.

FIG. 13 is a diagram illustrating an air volume sensing unit 210 of an air purifier 164 according to another embodiment, and FIG. 14 is a diagram illustrating a method of measuring an air volume using the air volume sensing unit 210 of FIG. 13 to be.

This embodiment may also use the conical inclination guide 211 as in the above-described embodiment, and may further include a piezo sensor disposed at the outlet of the inclination guide, as shown in (a) of FIG. 13. Since the amount of air introduced to the inlet (lower side in the drawing) and the air discharged to the outlet (upper side in the drawing) of the inclined guide 211 are the same, the pressure of the air passing through the narrow outlet side may increase.

The piezo sensor includes a piezo disk 216 that bends according to pressure, a sensor substrate 219 positioned around the outlet of the inclined guide 211, and a terminal contacting the piezo disk 216 to connect to the sensor substrate 219. I can.

The piezo disk 216 is a disk-shaped member, and may include a first disk 216a and a second disk 216b that are located on one surface of the first disk 216a and are smaller in size than the first disk 216a. have. When pressure is applied to the piezo disk 216, a signal is generated as the electronic arrangement between the first disk 216a and the second disk 216b is changed. The first disk 216a may include a metal, and the second disk 216b may be formed of a ceramic material.

Including a first electrode 217a connected to the first disk 216a and a second electrode 217b connected to the second disk 216b, and the piezo disk 216 is fixed to the outlet of the inclined guide 211 In order to do so, the electrode may be implemented in the form of a clip having a predetermined strength. 13B is a diagram showing one surface of the piezo sensor and (c) the other surface. The piezoelectric first electrode 217a and the piezo contacting the first disk 216a on the other surface of the piezo disk 216 It includes a second electrode 217b in contact with the second disk 216b on one surface of the disk 216. The piezo disk 216 is interposed between the first electrode 217a and the second electrode 217b, and the first electrode 217a and the second electrode 217b extend from the sensor substrate 219 and have a predetermined rigidity. The piezo disk 216 may be supported by including a material.

Since only the first disk 216a is located on the other surface of the piezo disk 216, the second electrode 217b can contact any other surface of the piezo disk 216, and the thickness of the first electrode 217a is shown in FIG. It can be formed uniformly as shown in ). Both ends of the first electrode 217a are supported on the sensor substrate, and are bent in a U shape to stably support the piezo disk 216.

Since both the second disk 216b and the first disk 216a are exposed on one surface of the piezo disk 216, the second electrode 217b should be configured not to directly contact the first disk 216a. The second electrode 217b is formed to have a thick portion of the portion that contacts the second disk 216b and the remaining portion is formed to be thin, so that the portion overlapping with the first disk 216a does not directly contact the piezo disk 216. In order to stably support the piezo disk 216, the second electrode 217b may be located in the middle of both points connected to the sensor substrate 219 of the first electrode 217a.

There is a difference in pressure applied to the piezo disk 216 when air does not pass as shown in FIG. 14(a) and when air passes as shown in FIG. 14(b), and the piezo disk 216 is bent. While losing, a signal may be generated as shown in (c) of FIG. 14. The amount of air passing through the piezo sensor can be measured based on the size or pattern of the signal.

In this way, the control unit can detect the amount of air discharged from the first outlet 16461a and the second outlet 16461b by using the air volume detection unit 210, and the first outlet 16461a and the second outlet 16461b The amount of air discharged can be adjusted. For example, the air purifier 164 may be controlled so as to discharge more air to the living room during a time when a large number of people are active in the living room, and to supply more purified air to the bedroom at night.

15 to 17 are views showing several examples of the air volume control unit of the air purifier 164, and the air volume control unit controls the amount of air discharged to the first outlet 16461a and the second outlet 16461b.

The air volume control unit 221 of FIG. 15 includes a gear that adjusts the angle of the blowing fan 1644, and the blowing fan 1644 has an angle as shown in FIGS. 15A and 15B according to the rotation of the motor. Change. If a sirocco fan that the blowing fan 1644 discharges in the lateral direction is used, the amount of air directed to the first outlet 16461a is increased as shown in FIG. 15(a) by adjusting the lateral direction of the sirocco fan, or FIG. 15 As shown in (b) of, the amount of air directed to the second outlet 16461b may be increased.

The air volume control unit 222 of FIG. 16 may include a rack pinion gear for adjusting the position of the blowing fan 1644. The blowing fan 1644 may be moved in the direction of the first outlet 16461a or the second outlet 16461b by using the rotational force of the motor. That is, the air volume control unit 222 of the present invention adjusts the position of the fan to increase the amount of air directed to the first discharge port 16461a as shown in FIG. 16(a) or the second discharge port as shown in FIG. 16(b). The amount of air directed to (16461b) can be increased.

The air volume control unit of FIG. 17 selectively moves the partition plate 16463 of the exhaust chamber between one side and the other side of the smart wall 100 to increase the amount of air directed to the first outlet 16461a as shown in FIG. 17A. Alternatively, as shown in (b) of FIG. 17, the amount of air directed to the second outlet 16461b may be increased.

18 is a diagram illustrating a control method of an air purifier 164 according to an embodiment. The air discharge amount of the first room (room 1) and the second room (room 2) is set to x% and y% (S11), and the air volume passing through each outlet is measured by detecting a signal from the air volume sensor 210 Do (S12). Here, the amount of air may not be an absolute amount of air, but may refer to a relative amount of air between the first outlet 16461a and the second outlet 16461b. After a predetermined time, the average value of the signal of the air volume detection unit 210 is calculated. Although it is shown as 60 seconds on the drawing, the average of more or less than that may be obtained (S13).

It is determined whether the measured value of the air volume sensor 210 located in the first outlet 16461a is higher than the set value x% (S14). If it is higher than x%, the controller may reduce the air volume of the first outlet 16461a and increase the amount of air passing through the second outlet 16461b by controlling the air volume control units 221 and 222 (S15).

When the measured value of the air volume sensing unit 210 located in the first outlet 16461a is lower than the set value x%, the measured value of the air volume sensing unit 210 located in the second outlet 16461b is the set value y% It is determined whether it is higher (S16). If it is higher than y%, the controller may reduce the air volume of the second outlet 16461b and increase the amount of air passing through the first outlet 16461a by controlling the air volume control units 221 and 222 (S17).

If the measured value in each air volume detection unit 210 is not greater than the set value, that is, if it is in balance, the measured value is initialized again and measured again (S18). The control unit of the present invention may adjust the amount of purified air supplied to the first room (room 1) and the second room (room 2) by using the air volume sensor 210 and the air

volume control parts

221 and 222.
