Description

Inflow Prevention Device for the Dust of the Window having Filter

The present invention relates to a device for preventing the inflow of dust into a window by using a filter member, and more particularly, to block dust entering through the window by improving the structure of a conventional filter member and installing it detachably on the window. In addition to keeping the indoor air clean, the filter member is standardized and standardized filter members are stacked and connected, but when stacked, the filter member has an uneven connection structure to improve sealing power between the filter members, and to arrange the pleats of the filter. The present invention relates to a device for preventing dust inflow of a window so as to eliminate waste of resources while providing ease of work for scrapped parts by changing the method and arrangement direction to cut and use the filter member according to the height of the window.

In general, in an enclosed space such as indoors, since the air becomes turbid by human breathing or activities, ventilation is required to open a window to discharge the turbid internal air and to receive clean outside air.

In particular, in schools where many people live together, windows are opened most of the time, except in winter or rainy weather, when heating is required, or when yellow dust or external noise is severe, to ventilate the interior and exterior of the building. Insect screens are sometimes installed to prevent inflow.

However, the insect screen is sized to prevent the inflow of pests and has a mesh structure that allows the inflow of external air.When external air is introduced, dust and the like are introduced together.In recent years, external air introduced into the room due to air pollution, etc. There is a tendency that a lot of fine dust, which is an air pollutant, is included as well as dust that is polluted in the air.When external air is introduced, fine dust enters the room and accumulates, or pathogens contained in the fine dust cause respiratory diseases. there was.

Accordingly, in order to block the inflow of dust or fine dust, indoor air is purged by installing an air purifier indoors with the window closed.

However, the air purifier alone cannot prevent the indoor air from becoming turbid, and if the capacity of the air purifier is exceeded, the air cleaning efficiency decreases, so damage caused by dust or fine dust cannot be prevented. Since respiratory diseases are caused, there is a limit in use, and improvement measures are still required to block the inflow of dust or fine dust, which are harmful substances contained in the outside air, into the room.

In other words, if you live with the window closed, the indoor air becomes cloudy, and if you open the window, dust or fine dust enters and pollutes the room.

On the other hand, as described above, as a new method for blocking the inflow of dust or fine dust contained in the outside air into the interior, recently, a method of installing a filter member on the window side has been proposed and used. Standard product filter members with arranged pleats but vertically arranged for each pleat are used, and filter members of standard products having such an arrangement structure and arrangement method are simply stacked on the window frame to prevent dust indoors. Inflow is prevented.

However, as described above, in the conventional method of installing using a filter member, a filter member having a pleated portion continuously arranged in the left and right direction is simply placed on the window frame with a filter member of a standard product in which each pleat node is vertically arranged. As a result, it is installed in a sequentially stacked form, and thus, a scrapped portion in which the standard filter member cannot be completely disposed on the upper or lower end of the window frame occurs. At this time, the standard filter member should be cut according to the scrap, and the standard filter member had to be cut in a direction that crosses each vertically arranged pleat, so there was a difficulty in the cutting process. In spite of the disadvantage of not being able to maintain durability on the side of the filter member when cutting in the direction crossing the pleat joints, there is no other method, so it is used as the conventional installation method.

In addition, in the conventional installation method using a standard filter member, there is a problem of uneconomicality due to severe waste of resources because unused parts have to be discarded after cutting. When installing by stacking, assembling and durability as well as sealing properties are poor and installation time is required. There was a problem.

Furthermore, in the method of using the filter member of the conventional standard product, a filter support member for easily installing and supporting the filter member is used together. However, due to structural disadvantages, a gap is generated between the window frame and the interior There was a problem in that dust and the like could enter with the wind.

Terms used in the present invention are terms defined in consideration of functions in the present invention, and since these may vary according to the intention or custom of users or operators, the definitions of these terms correspond to the technical matters of the present invention. And should be interpreted as a concept.

1 to 7 are views illustrating a device for preventing dust inflow of a window according to the present invention, and FIGS. 8 to 10 are diagrams illustrating a process of installing a device for preventing dust inflow of a window according to the present invention. .

As shown in Figs. 1 to 7, the device for preventing dust inflow of a window according to the present invention includes a door frame 40 having a square shape installed in a building; A filter installed on the window to block the inflow of dust or fine dust as being installed on a window including two or more window frames 30 provided with a glass window 35 and installed to be horizontally movable on the door frame 40 Member 20; And a filter support member 10 that is detachably installed on the door frame 40 and the window frame 30 of the window to support the filter member 20.

The door frame frame 40 is a pair of vertical frame members 41 which are arranged at regular intervals and each having a plurality of vertical guide rails 42 formed on the inner surface thereof, and a horizontal guide rail connected to the vertical guide rail 42 A plurality of 44 is formed and consists of a pair of horizontal frame members 43 connecting the upper and lower ends of the vertical frame member 41, respectively. In addition, the window frame 30 supports both sides of the glass window 35 and includes a pair of vertical frame members 31 having grooves 31 ′ in which the vertical guide rails 42 are accommodated, and the upper surface of the glass window 35 And a pair of horizontal frame members 33 formed with grooves that support the bottom and horizontal guide rails 44.

At this time, a pair of window frames 30 may be installed in the front and rear directions on the door frame frame 40 so as to cross each other, and one is installed in the middle portion of the door frame frame 40, and a total of 3, one at each side so as to cross each other. Dogs may be installed. When three window frames 30 are installed on the door frame 40, the window frame 30 located in the middle may be installed in a fixed or movable manner. In addition, the window frames 30 located on both sides of the window frame 30 located in the middle may be disposed both in front or behind the window frame 30 located in the middle, one in front of the other It can also be placed in the back. In addition, four vertical guide rails 42 and horizontal guide rails 44 are formed on the vertical frame member 41 and the horizontal frame member 43 constituting the door frame frame 40, respectively, so that the first A window frame 30 is installed on each of the guide rails 42a, 44a and the second guide rails 42b, 44b to form an inner window, and the third guide rails 42c, 44c and A double-glazed window may be formed by forming an outer window by installing a window frame 30 on each of the fourth guide rails 42d and 44d.

In addition, a filter support member 10 is installed on the vertical frame member 31 of the window frame 30 and the vertical frame member 41 of the door frame 40, respectively, and the filter member 20 is attached to the filter support member 10. By combining, it is possible to keep the indoor air clean by removing dust and fine dust contained in the air introduced from the outside during ventilation.

Meanwhile, the filter support member 10 includes an intermediate plate 11 formed in a vertical direction and in close contact with the side of the window frame 30 or the door frame 40, and the vertical frame member 41 of the door frame 40 Four coupling protrusions 12 protruding in a right angle direction from one side of the intermediate plate 11 so as to be elastically coupled to the side of the vertical frame member 31 of the plurality of vertical guide rails 42 or window frame 30 formed in the , It includes a pair of support protrusions 13 protruding in a right angle direction from the other surface of the intermediate plate 11 to accommodate the filter member 20.

At this time, the pair of support protrusions 13 extend the length so that the upper and lower ends are in close contact with the ceiling surface and the floor surface of the pair of horizontal frame members 43 respectively located on the upper and lower sides of the door frame frame 40. It is configured to prevent the formation of a gap between the horizontal frame member 43 and the support protrusion 13 by protruding to block the inflow of wind and dust.

Here, the number of the coupling protrusions 12 is not necessarily formed of four, but may be formed of five or more depending on the structure of the window frame 30 or the door frame 40. In addition, it is more preferable that an inclined surface is provided at the end of the coupling protrusion 12 so as to be inserted naturally without interference when it is coupled to the window frame 30 or the door frame 40.

Accordingly, the filter support member 10 is firmly coupled to the vertical frame member 31 of the window frame 30 or the vertical frame member 41 of the door frame frame 401 using a plurality of coupling protrusions 12. It becomes possible, and it is possible to stably support the filter member 20 by using a pair of support protrusions 13.

At this time, the support protrusions 13 are formed inside the ends of the intermediate plate 11, respectively, and the first coupling protrusion 12a and the fourth coupling protrusion 12d located at the outermost of the coupling protrusions 12 are the support protrusions ( 13) is preferably formed on the outside. That is, the support protrusions 13 are respectively formed inside the ends of the intermediate plate 11 so that the filter member 20 is located in the middle portion without being biased toward any one of the front and rear directions of the filter support member 10, and the filter member The first coupling protrusion 12a and the fourth coupling protrusion 12d are formed on the outside of the support protrusion 13 so that the 20 is stably supported.

In addition, it is preferable that the first coupling protrusion 12a is formed to be orthogonal to one end of the intermediate plate 11 and the other end extends outward than the fourth coupling protrusion 12d. Of course, when the filter support member 10 is installed, the part where the intermediate plate 11 is extended should face the indoor side, and the intermediate plate 11 should not protrude compared to the window frame 30. Accordingly, the middle plate 11 and the first coupling protrusion 12a are orthogonal to each other on the outside of the window, so that the aesthetic feeling is not deteriorated, and the middle plate 11 is in close contact with the window frame 30 on the inside of the window.

In addition, by installing a sealing member 36 such as Munpungji between the two window frames 30 overlapping each other, it is possible to prevent external air from flowing into the gap with the window frame 30.

In addition, it is preferable that the plurality of coupling protrusions 12 provided on the intermediate plate 11 are formed so that the spacing between them is not uniform. That is, the distance between the coupling protrusions 12 is determined according to the structure of the vertical frame member 31 of the window frame 30 and the vertical guide rail 42 installation structure of the vertical frame member 41 of the door frame frame 40. Although it can be done, it is possible to apply to various types of window frames 30 and door frame frames 40 by varying the spacing between the coupling protrusions 12.

In more detail, the coupling structure of the window frame 30 and the door frame 40 and the filter support member 10 will be described as follows.

In the case of installing the filter support member 10 on the window frame 30, the third coupling protrusion 12c and the third coupling protrusion 12 of the coupling protrusion 12 of the filter support member 10, as shown in FIG. 4 The coupling protrusions 12d are installed to be in close contact with the inner wall of the groove 31 ′ formed in the vertical frame member 31, and the second coupling protrusions 12b are installed to be in close contact with the outer surface of the vertical frame member 31. . In this case, the first coupling protrusion 12a serves as a reinforcing member. However, when the thickness of the vertical frame member 31 constituting the window frame 30 is wider, the second coupling protrusion 12b is not the outer side of the vertical frame member 31 but the inner wall of the groove 31 ′ In close contact with the third coupling protrusion (12c) may be to perform the role of the reinforcing material. In addition, when the filter support member 10 is installed on the door frame frame 40, the third coupling protrusion 12c and the fourth coupling protrusion 12d among the coupling protrusions 12 of the filter support member 10 are vertical frames. Each of the first guide rails 42a formed on the member 41 is in close contact with both sides, and the first coupling protrusion 12a is installed to be in close contact with the side surfaces of the second guide rails 42b. In this case, the second coupling protrusion 12b serves as a reinforcing member. Accordingly, the versatility of the filter support member 10 is greatly improved.

And, the support protrusion 13 is preferably smaller as long as it can stably support the filter member 20, but is formed to a size such that the filter member 20 is not separated even if wind acts on the filter member 20. It is desirable.

In addition, the length of the coupling protrusion 12 is the depth of the groove 31 ′ formed in the vertical frame member 31 of the window frame 30 or the guide rail 42 formed in the vertical frame member 41 of the door frame frame 40. ), but it is determined according to the height, but is preferably formed based on the smallest of the commercial window frame 30 and the door frame 40. This is intended to be used regardless of the depth of the groove 31 ′ formed in the commercial window frame 30 and the height of the guide rail 42 of the door frame 40. However, the longer the length of the coupling protrusion 12, the stronger the coupling force, so the length of the coupling protrusion 12 is formed longer, but the depth of the groove 31 ′ formed in the window frame 30 compared to the length of the coupling protrusion 12 It may be formed to be foldable so that it can be used even when is shallow or the height of the guide rail 42 of the door frame 40 is low.

In addition, the filter support member 10 is best formed to have a length corresponding to the height of the window, but it cannot be used if the height of the window is different, and productivity is degraded due to products of too many sizes. Therefore, it is desirable to standardize the length of the filter support member 10 to produce a product having a certain length. Accordingly, when the size of the window is larger or smaller than the standardized filter support member 10, the standardized filter support member 10 is cut or connected to correspond to the height of the window.

In addition, the filter member 20 is inserted and coupled to the filter body 21 that filters dust and fine dust, and the filter support member 10, and is installed along the edge of the filter body 21 to support the filter body 21 It consists of a filter frame (22). At this time, it is preferable to use a known HEPA (High Efficiency Particulate Air) filter or a ULPA (Ultra Low Particulate Air) filter as the filter body 21. The HEPA filter is a filter that can remove more than 99.95% of fine dust of 0.3㎛ or more, and the Woolfa filter is a filter that can remove more than 99.9995% of fine dust.

At this time, the height of the filter member 20 may vary depending on the size of the window, but it is preferable to use a standardized filter member 20, and the standardized filter member 20 is lower than that of the filter support member 10. It is more preferable to have a height. Further, the standardized filter member 20 is laminated and bonded to the filter support member 10, and the filter member 20 may be cut and used if necessary. Therefore, it is possible to use the standardized filter member 20 and the filter support member 10 regardless of the size of the window.

In particular, the filter body 21 has a pleat portion by the pleat nodes 21a that are continuously arranged in the vertical direction, and is installed so that each pleat node 21a forming the pleat has a horizontal arrangement structure. That is, through the horizontal arrangement structure, the filter member can be cut to correspond to windows having various heights according to the installation site, and they can be connected to each other to be used.

Here, the pleats 21a forming the pleats are provided in a form in which 50 or more grains are continuously arranged for efficiency according to the use of the filter member 20.

At this time, the filter member 20, referring to FIGS. 5 and 6, has a configuration including and attaching a sealing member 23 for providing airtightness along the outer edge of the filter frame 22, but the thickness By attaching to be positioned in one direction of the front and rear sides to form a stepped structure to be disposed.

In this way, through the sealing member 23 forming the stepped structure, the filter member 20 is connected in the vertical direction according to the height of the window, and the sealing member 23 forming the stepped structure is positioned in the front and rear directions when stacked. It can be installed so that the concave-convex connection is made between the filter members 20 that are connected and stacked in the vertical direction by placing them.

Here, the sealing member 23 is preferably a sponge having elasticity.

Here, when the filter member 20 is connected in an up-down direction according to the height of a window having various heights according to the installation site, the entire filter member 20, which is a standard product, cannot be used and has a scrap portion that must be cut and used. In this case, the filter member 20 has a pleat portion by pleat nodes 21a that are continuously arranged in the vertical direction, but has a horizontal arrangement structure for each pleat node 21a, and is easy to fit in the area or space of the scrapped portion. It provides an advantage that can be cut and used, and the remaining filter member 20 that has not been used after being cut provides an advantage that can be reused without discarding.

In addition, the filter member 20 has pleats that are continuously arranged in the vertical direction, but the reinforcing bars 24 at the upper and lower ends of the filter body 21 side are installed so that the pleats 21a forming the pleats have a horizontal arrangement structure. It is composed in the form of attaching and padding.

At this time, through the reinforcing bar 24, it is possible to prevent sagging of the pleat portions forming the filter body 21, as well as secure and reinforce the overall durability of the filter member 20 side.

In addition, the filter member 20 is used by connecting and stacking the filter member 20 in an up-down direction so that the filter member 20 is cut to fit the height of the window and covered and mounted when in use, and the filter member 20 is connected and stacked in the vertical direction. It further includes a support clip member 50 so as to support the corrugated joints (21a) adjacent to each other on the connection side by inserting and assembling them to support them. Through this, the corrugated joints 21a connected to each other are prevented from sagging in a downward direction, that is, in a vertical direction, and are in close contact with each other to improve sealing force.

At this time, the support clip member 50 has a length corresponding to the length of the corrugated joint 21a so as to cover the length of the corrugated joint 21a horizontally disposed on the corrugated portion side, but has a digut (c) shaped cross section to facilitate fitting and assembly It is provided in the form of a structure.

Here, the support clip member 50 can be used to support the pleat nodes 21a and the pleat nodes 21a adjacent to each other on the filter member 20 side, as well as sandwiching the sealing member 23 between the filter members. By inserting and assembling the upper and lower filter frames 22 and the filter frames 22 in a form that covers them, they can be used in various ways, such as using them in a form that provides support to them.

The installation and operation of the device for preventing dust inflow of the window of the present invention configured as described above will be described as follows.

In the rest of the seasons, except in winter, when the windows are closed to prevent heating heat from being emitted to the outside, a device to prevent dust inflow is installed on the windows. That is, after the windows are opened to a certain extent, by installing the dust inflow prevention device having the above-described configuration between the open windows, dust or fine dust is prevented from entering through the open windows.

First, as shown in (a) of FIG. 8, one side of the window frame 30 is moved along the horizontal guide rail 44 of the door frame 40 to open the window. At this time, it is preferable to open the window wider than the width of the filter member 20. This is to facilitate the installation of the filter member 20.

Next, as shown in (b) of FIG. 8, filter support members 10 are installed on the vertical frame member 31 of the window frame 30 and the vertical frame member 41 of the door frame 40, respectively. That is, two or more of the plurality of coupling protrusions 12 provided in the filter support member 10 are in close contact with the inner or outer surface of the groove 31 ′ formed in the vertical frame member 31 of the window frame 30 The filter support member 10 is installed on the window frame 30 to be elastically coupled, and two or more of the plurality of coupling protrusions 12 provided on the other filter support member 10 are vertical frames of the door frame frame 40 The filter support member 10 is installed on the door frame frame 40 so that it is in close contact with the inner or outer surface of the vertical guide rail 42 provided on the member 41 and is elastically coupled. At this time, when the length of the filter support member 10 is larger than the height of the window frame 30 or the door frame 40, the filter support member 10 is cut and used, and the length of the filter support member 10 is If it is shorter, the filter support member 10 is stacked and used. In addition, the filter support member 10 is installed so that the intermediate plate 11 is in close contact with the side surface of the window frame 30 or the end surface of the vertical guide rail 42 formed on the door frame frame 40.

Here, the pair of support protrusions 13 are in close contact with the upper and lower ends of the ceiling surface and the bottom surface of the pair of horizontal frame members 43, respectively located on the upper and lower sides of the door frame 40, through which It is possible to block the inflow of wind and dust by preventing a gap from being formed between the horizontal frame member 43 and the support protrusion 13.

When the installation of the filter support member 10 is completed, as shown in (c) of FIG. 9, the filter support member coupled to either side of the window frame 30 or the door frame 40, preferably the door frame 40 Insert and install the filter member (20) in (10). The filter member 40 is installed in the form of being inserted between the support protrusions 13 of the filter support member 10 from the side of the filter support member 10, and the filter member 20 inserted as shown in (d) of FIG. ) To move downward and install in a stacked form. At this time, the lower part of the filter member 20 located at the lowest end or the upper part of the filter member 20 located at the top end is between the horizontal guide rail 44 formed on the horizontal frame member 43 of the door frame frame 40. It should be installed so that it is not exposed to the outside by being inserted. This is to block external air from flowing into the gap between the horizontal frame member 43 and the filter member 20 of the door frame frame 40.

At this time, since the stacking filter members 20 are stacked and connected in an uneven structure by using the sealing member 23 arranged to form a stepped structure, the sealing property between the upper and lower stacked filter members 20 can be improved, and the support clip member By assembling the filter members 20 on which 50 is stacked, it is supported so that it is possible to prevent sagging on the side of the folds 21a arranged horizontally.

Here, when the filter member 20 is stacked, the filter member 20 can be cut and used when a scrap portion remains. In the present invention, the filter member 20 is arranged horizontally with respect to the pleat joint 21a on the side of the filter member 20 Since it provides a structure, it can be easily cut horizontally to fit in the scrap space and used, and the unused filter member 20 after cutting can also be reused since it is not damaged.

As described above, when the installation of the filter member 20 is completed, as shown in FIG. 10, the filter member () between the support protrusions 13 of the filter support member 10 installed on the window frame 30 by closing the window as shown in FIG. By allowing the side of 20) to be inserted, the filter member 20 is fixed to prevent separation. In addition, in order to block the air from flowing between the other side vertical frame member 31 of the window frame 30 and the glass window of the other window frame 30, the other vertical frame member 31 of the window frame 30 is provided with A sealing member 36 is installed to seal between the glass window 35 and the vertical frame member 31.

Accordingly, during ventilation, the air introduced from the outside of the building passes through the filter body 21 of the filter member 20 and flows into the room, so that dust and fine dust are filtered out by the filter body 21 and there is no fine dust. Only clean air enters the room. Accordingly, it is possible to maintain the indoor air in a clean state, and respiratory diseases caused by dust or fine dust can be prevented. In addition, since the inflow of pollen or yellow dust, which is larger than fine dust, is also blocked, allergic diseases can also be prevented.

And when all windows must be closed, such as in winter, by separating the filter member 20 and the filler support member 10 in the opposite order of the above order, the high temperature indoor air is discharged to the outside by closing the window. So that the heating efficiency does not decrease.
