The basic feature of the technology is that air quality in a large-scale space that is difficult to maintain confidentiality due to a large floating population can be made to operate periodically according to a predetermined time or when no human movement is detected. do.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings as follows.

As shown in Figure 1, the mist spray type plimer diffuser according to the present invention is installed in communication with the duct 2, and a plimer filter 100 for filtering foreign substances from passing air; A diffuser head 200 provided in the through hole formed in the ceiling 1 to allow air to flow between the plurality of inclined wings 210 and 220; A damper 300 capable of adjusting an opening degree of a cross-sectional area communicating between the plimer filter 100 and the diffuser head 200; It is preferable to include a nozzle 400 positioned on the bottom of the diffuser head 200 to spray mist.

That is, the mist spray type plimer diffuser of the present invention may largely include a pimmer filter 100, a diffuser head 200, a damper 300, and a nozzle 400.

First, the plimer filter 100 is installed in communication with a duct 2 such as a flexible pleated pipe and is configured to filter foreign substances from passing air. As shown in FIG. 2, a plurality of filter fibers 110 are circular or It is provided with directionality along the longitudinal direction in the rectangular hollow casing 120.

Therefore, the plimer filter 100 may be manufactured in a module such as a cylindrical shape or a square column shape, and it is possible to conveniently replace the module when replacing.

In addition, one end of the plurality of filter fibers 110 is supported by the bridge 130 in the casing 120, so that the location where the bridge 130 is located corresponds to the inlet side.

Therefore, if the mist spray type plymer diffuser of the present invention is used as a supply port, the bridge 130 will be located toward the duct 2 side as shown in FIG. 2 in the plimer filter 100, and the exhaust port When used for the purpose of, although not shown, the bridge 130 will be positioned toward the diffuser head 200, which will be described below.

That is, the mist spray type plimer diffuser of the present invention only makes a difference only in the directionality of the plimer filter 100 and can be selectively used as an exhaust port as well as an air supply port.

Such a plimer filter 100 is a kind of filter disclosed in Korean Patent Publication No. 10-0763605. As a filter having low air resistance but high filtration efficiency, grade 7 or higher of EN779:2012 will be appropriate.

Accordingly, the plimer filter 100 may be manufactured as a module and provided in the container-shaped housing 101.

And, as shown in Figure 4, when only one of the plimer filter 100 is disposed in the housing 101, the housing 101 is simply shaped to correspond to the outer shape of the plimer filter 100. Can be made.

For example, for one plimer filter 100, when the plimer filter 100 has a cylindrical shape, the housing 101 is also formed in a cylindrical shape, and the plimer filter 100 has a square column shape. In this case, as shown in FIG. 4, the housing 101 can also be formed into a square column shape corresponding thereto.

However, as shown in FIG. 3, it is also possible to provide two or more plimmer filters 100 in one housing 101.

In this case, the housing 101 may have a rectangular column shape while the plimer filter 100 may have a cylindrical shape, and although not shown, the housing 101 has a cylindrical shape, whereas the pimmer filter 100 has a rectangular shape. It could be a column shape.

At this time, in the case of applying the cylindrical plymer filter 100 in the rectangular column-shaped housing 101, as shown in FIG. 3, the water supply pipe 410 to be described below is disposed through a free space formed therebetween. It will be possible.

Therefore, the shape of the plymer filter 100 and the housing 101 that can accommodate the same will not be limited in its shape, such as a cylinder, a square pillar, and a polygonal column, and the housing 101 and the plimer filter 100 The shapes of may be the same or different shapes.

Next, the diffuser head 200 is provided on the ceiling 1, and when the diffuser of the present invention is used for an air supply (reference numeral 3 in FIGS. 11 to 14), fresh air from the duct 2 to the room When used for the purpose of supplying air and an exhaust port (reference numeral 4 in FIGS. 11 to 14), it serves to exhaust the contaminated air in the room to the duct 2.

At this time, the shape of the diffuser head 200 will not be limited in its shape, such as a circle or a square, and a through hole corresponding to the shape of the diffuser head 200 is provided in the ceiling 1 for installation of the diffuser head 200. Is formed.

In addition, the diffuser head 200 is provided with a plurality of inclined blades (210, 220), the air is to flow between the inclined blades (210, 220).

In particular, the inclined blades 210 and 220 are formed to be tapered so that the upper part has a narrower cross-sectional area than the lower part by forming a concentric circle as shown in FIG. 5 or a concentric square as in FIG. 6 based on the center thereof, and the inclined blade 210 , 220) are installed parallel to each other.

According to the configuration of the inclined blades 210 and 220, the diffuser head 200 may collect and exhaust contaminated air near the ceiling 1, or supply fresh air to the interior evenly.

At this time, the diffuser head 200 has the same inclination angle and shape as the inclined wings 210 and 220 as shown in FIG. 1, but has the widest area and a catch 201 spanning the lower edge of the through hole of the ceiling 1 Is formed, it is possible to install the diffuser head 200 so as not to protrude below the ceiling (1).

Accordingly, the diffuser head 200 is in harmony with the surface of the ceiling (1), and air supply or exhaust can be performed in a 360-degree radial direction parallel to the ceiling (1), which is particularly suitable for structures with a low floor height. will be.

Such a diffuser head 200 may be manufactured with good formability through synthetic resin, but in consideration of strength and durability, a metal material such as steel, aluminum, and stainless steel will be preferable.

In addition, it is possible to minimize air leakage and increase a sense of unity with the surface of the ceiling (1) by adding a rubber gasket, not shown, to the edge between the catch 201 and the ceiling (1).

Next, the damper 300 is provided in the middle of a passage communicating between the plimer filter 100 and the diffuser head 200 and has a configuration capable of controlling the amount of air supply or the amount of exhaust by adjusting the opening degree of the cross-sectional area.

Such a damper 300 may be applied in various forms, and it will be possible to adjust the opening degree of the damper 300 according to an electrical signal by placing a separate driving member 500 as described later or according to a user's manipulation. .

First, as an example of the damper 300 for controlling the opening degree according to the user's manipulation, as shown in FIG. 7, a lever 310 guided in a straight line for a predetermined section; A ring-shaped member, the locking protrusion 321 protruding from one outer circumference thereof is connected to the lever 310, and the control ring 320 rotates forward and backward according to the reciprocation of the lever 310; It is arranged in a radial shape and guided to each of the control ring 320, a plurality of pivoting blades 330 for opening and closing the center of the control ring 320 by turning in an arc according to the forward and reverse rotation of the control ring 320 Can be done.

That is, the damper 300 made of the lever 310, the control ring 320, and the swing blade 330 is provided on one side so that the lever 310 can flow in one direction in a predetermined section, and the position of the lever 310 Accordingly, the control ring 320 rotates in a forward and reverse direction by a predetermined angle based on its center.

At this time, the orbiting blade 330 in which the disk is approximately divided into four is supported to be rotatable and guided by the control ring 320, so that it is formed in the center while rotating radially according to the rotation of the control ring 320. It opens and closes the circular hole.

7(a) shows a state in which the turning blade 330 is opened by pushing the lever 310 to the left in the drawing and rotating the control ring 320 in a clockwise direction, and FIG. 7(b) shows the lever ( 310) is pushed to the right in the drawing to rotate the control ring 320 in a counterclockwise direction, thereby indicating a state in which the orbiting blade 330 is closed.

Accordingly, not only can the damper 300 be opened or closed according to the user's manipulation of the lever 310, but also the opening amount can be arbitrarily adjusted, so that the amount of air supply or the amount of exhaust can be easily adjusted.

On the contrary, another example of the damper 300 is provided with two circular plates 340 and 350 as shown in FIG. 8 but with a phase angle difference along the circumferential direction and through holes 341 ( 351) is formed to intersect.

Then, in a state in which two circular plates 340 and 350 are overlapped and arranged, one of the two circular plates, for example, the upper plate 340 is fixed and rotated to the center of the other plate 350 The knob 360 is connected.

In this case, the rotation knob 360 may extend below the above-described diffuser head 200.

According to this configuration, it is possible for a user to rotate only the rotating plate 350 by turning the rotation knob 360 based on the fixed plate material 340.

As above, in addition to adjusting the opening amount of the two plate members 340 and 350 through rotation, although not shown, for example, two plate members 340 in which through holes 341 and 351 are respectively formed according to linear movement in one direction. It would of course be possible to adjust the opening amount of 350.

As a result, when the through hole 341 formed in the fixed plate material 340 and the through hole 351 formed in the rotating plate material 350 are aligned, the through hole 341 is opened, and the through hole 341 formed in the fixed plate material 340 If the through hole 351 formed in the and rotating plate 350 is not aligned, it is in a closed state, and of course, it is possible to arbitrarily adjust the opening amount through this.

As described above, the user may manually adjust the opening degree of the damper 300 directly, and preferably, a separate driving member 500 is provided so that the driving member 500 is used as the damper 300 according to an electrical signal. It is good to be able to control the opening of the body.

As described above, the control of the driving member 500 to adjust the opening degree of the damper 300 will be described in detail below.

Next, the nozzle 400 is located on the bottom of the diffuser head 200 and is configured to spray supplied water or a liquid such as a disinfectant harmless to the human body in a mist state.

To this end, a water supply pipe 410 for supplying water or a disinfectant to the nozzle 400 is provided as illustrated in FIG. 1, and this water supply pipe 410 is between the plimer filter 100 as shown in FIG. 3. It may be arranged as a space, and although not shown, it may be provided separately inside or outside the housing 101.

According to this configuration, the mist spray type plimer diffuser according to the present invention may be used as a supply port or an exhaust port, and the opening amount may be controlled through the damper 300.

In particular, by supplying water or a disinfectant to the nozzle 400, it is possible to remove by adsorbing and dropping the fine dust floating in the area by spraying the mist within a radius of approximately 1.5 m near the diffuser.

Until now, in the mist spray type plymer diffuser of the present invention, the user directly controls the opening degree of the damper 300 and determines whether to spray mist according to whether or not the liquid is supplied through the water supply pipe 410, but hereinafter It will be described with respect to the remote active control of the opening degree of the damper 300 and whether or not mist is sprayed.

To this end, in the present invention, the driving member 500 for controlling the opening degree of the damper 300 by driving according to an electrical signal; An injection member 600 that is driven according to an electrical signal to control whether or not to intermittently spray the liquid supplied to the nozzle 400; The driving member 500 and the injection member are connected to the driving member 500 and the injection member 600 and provided with a timer 710 or according to the motion sensing means 720 or an electrical signal transmitted from the outside. It would be desirable to further include a control unit 700 for controlling the member 600.

First, the driving member 500 is for controlling the opening degree of the damper 300 by driving according to an electrical signal, and may be, for example, a solenoid mechanism or a stepping motor.

That is, as shown in FIG. 9, for an example of the damper 300 described above, a driving member 500 such as a stepping motor is additionally provided, so that the rotation angle of the driving member 500 with respect to the driving shaft is adjusted according to an electrical signal. Control, and a pinion 510 gear is provided on the drive shaft of the driving member 500, and a rack 520 gear is provided on the lever 310, so that the rack 520 and the pinion 510 are engaged with each other. By doing so, it will be possible to adjust the opening degree of the damper 300 described above.

In addition, for another example of the damper 300 described above, the opening degree of the damper 300 may be adjusted by connecting the drive shaft of the driving member 500 instead of the rotation knob 360 as shown in FIG. 10. There will be.

That is, it is possible for the rotating plate member 350 to rotate by the driving shaft of the stepping motor, which is the driving member 500.

According to this configuration, it is possible not only to directly adjust the opening degree of the damper 300 by the user, but to remotely control the opening degree of the plurality of dampers 300 collectively or individually.

In addition, the spray member 600 shown in FIG. 1 is a component that controls whether or not to spray liquid by controlling the liquid supplied to the nozzle 400 by driving according to an electrical signal.

The injection member 600 may include a valve mechanism therein, and the nozzle 400 serves to increase pressure to a pressure that may be required to spray water or a disinfectant into a mist.

As a result, it is possible to collectively or individually control whether or not mist is sprayed for a plurality of nozzles 400, not only by controlling whether or not to spray the mist by supplying water or disinfectant supplied to the water supply pipe (410). .

Finally, the control unit 700 illustrated in FIGS. 11 and 13 is a configuration that is connected to the driving member 500 and the injection member 600 by wire or wirelessly to collectively control them.

Accordingly, the control unit 700 controls the driving member 500 through the built-in timer 710 so that the damper 300 increases or decreases the amount of air supply or the amount of exhaust at a predetermined time period or the injection member 600 ), and it will be possible to control to spray mist at a predetermined time.

Additionally, a motion sensing means 720 may be additionally connected to the control unit 700, and the motion sensing means 720 is a bottom surface of the diffuser head 200, more preferably a nozzle 400, as shown in FIG. It could be prepared together.

Accordingly, the control unit 700 detects the motion in the motion detection means 720 and checks the presence of a passerby by itself, so that the spray member 600 sprays the mist only when there is no passerby, that is, a motion is not separately detected. ) Would also be possible.

Through this, it will be possible to prevent discomfort from spraying mist on passersby.

In particular, a plurality of mist spray type pimmer diffusers according to the present invention are arranged in a tiled manner in rows and columns, and all of them are connected to one control unit 700 by wired or wirelessly, so that one control unit 700 is It would also be possible to collectively control multiple diffusers.

11 and 12 are diagrams showing an example in which the mist spray type plymer diffuser of the present invention is installed in the platform 7 of the subway 6, and for convenience of explanation, the diffuser of the present invention is shown along the platform 7 It is illustrated that the air inlet 3 and the exhaust port 4 are arranged in one row, respectively.

According to this, for example, all diffusers simultaneously spray mist at the same time during the late night or early morning when there are no pedestrians, or control the supply or exhaust volume to be small, and during the daytime when pedestrians are present, all diffusers minimize the spray of mist. It becomes possible to greatly control the amount of air supply and the amount of exhaust.

Of course, it is also possible to prevent mist from spraying only a few diffusers provided in the area where the movement of pedestrians is detected, even in the late night or early morning hours, or to increase the amount of air supply or exhaust of some diffusers provided in the corresponding area.

On the other hand, even during the daytime, it may be possible to make the mist spray only a few diffusers provided in an area where no motion is detected, or to control the supply or exhaust amount of some diffusers provided in the corresponding area to be small.

Hereinafter, the operation of the present invention will be described with reference to the drawings.

As shown in Figs. 7 and 8, the mist spray type plymer diffuser configured as described above can be manually supplied or discharged by a user manipulating the lever 310 or the rotation knob 360 of the damper 300. It is possible to adjust the increase or decrease.

In addition, it is possible to control whether or not mist is sprayed by controlling the liquid supplied to the nozzle 400.

However, by adding a driving member 500 to control the opening amount of the damper 300, or by placing an injection member 600 to spray the mist to the nozzle 400, the control unit 700 remotely collectively controls It becomes possible.

In this case, the control unit 700 may perform control through the timer 710 or the motion detection means 720 according to a time zone or whether a movement of a pedestrian is detected.

By connecting a plurality of diffusers arranged as a supply port 3 or an exhaust port 4 in rows and columns to one control unit 700, a plurality of diffusers are collectively controlled at a time set by the timer 710. It becomes possible.

In addition, it is possible to control whether or not to spray mist or to increase or decrease the amount of air supplied or the amount of exhaust only for the diffuser in which motion is detected through the motion detection means 720 or only in a predetermined time period.

In particular, in the present invention, for example, in a state in which a plurality of diffusers are installed as the supply port 3 or the exhaust port 4 in the platform 7 of the subway 6, for example, the subway 6 is the platform ( Before entering 7), the operation of the exhaust port 4 is stopped for a predetermined time, for example, 1 minute before, and the operation of the air supply port 3 is increased so that the inside of the platform 7 is maintained in a positive pressure state. It is possible.

In this state, the moment the subway 6 enters the platform 7 and the screen door 5 is opened, the air inside the platform 7 in a positive pressure state as shown in FIGS. 13 and 14 is in a lower pressure state. It would be desirable to be able to supply fresh air to the inside of the subway 6 by rapidly entering the inside of the subway 6 in a short time.

Therefore, the mist spray type plymer diffuser of the present invention can be effectively removed by spraying mist from a ceiling-mounted diffuser that can be used as an air supply port 3 or an exhaust port 4 depending on the application and adsorbs it to fine dust floating in the air. In particular, it is possible to significantly improve air quality in a large-scale space where it is difficult to maintain airtightness due to a large number of flows by allowing the mist to be sprayed periodically according to a predetermined time or when no human movement is detected. It is an invention with an excellent advantage that there is.
