The ventilation device according to Embodiment 1 of the present invention according to the drawings largely consists of a ventilation main body 10, an opening/closing control part 20, a female condensation part 15, and a ring-shaped fastening member 17.

As shown in FIGS. 2 and 3 of the drawings, the ventilation body 10 is,

A cylindrical body portion 11 with openings at the front and rear ends, an inclined surface 131 extending to an expanded diameter along the edge at the top of the body portion 11 and sloping inward, and an inner wall surface 133. And, inside the body portion 11, a flange portion 13 consisting of a flange 132, and an airflow passage portion 14 forming a front first passage 141 and a rear second passage 142. It is formed to have a gap (“a”) below the inclined surface 131 of the airflow passage portion 14 when opened, and the ventilation device 10 is installed along the outer wall surface 11 of the body portion 11. When installing, a plurality of locking protrusions (16) whose installation height can be adjusted by ring-shaped fastening members (17) are formed on the ceiling along the outer wall surface (11) in multiple rows.

Therefore, the ventilation main body 10 is pushed into an installation hole such as a duct hole or ceiling, and the locking protrusion 16 is installed on the ceiling, duct hole, etc. through the ring-shaped fastening member 17.

The female condensation portion 15 forms a guide pipe body 151 having a predetermined length with a cylindrical cross section of a predetermined diameter at the center of the airflow passage portion 14 of the ventilation main body 10, and this guide pipe body 151 and the body portion 14 At least two supports 152 are formed radially between the inner walls of the guide pipe body 151, and a filter part 153 is formed between these supports 152, and the supports 152 Guide protrusions 154 may be formed at predetermined spiral intervals on the inner wall surface 133 of the inner guide tube body 151.

The opening and closing control unit 20 forms a disc-shaped cap part 21 that opens and closes and adjusts the gap "a" of the open space below the first passage 141 of the flange part 13, and the lower part of this cap part ( A predetermined length extends upward from the center of the bottom of 21) to form a cross-shaped shaft blade 222, and spiral grooves 221 are formed in a spiral shape at the end of the shaft blade 222, and between the shaft blades 222 A male shaft portion 22 forming a passage “b” for passing air can be formed.

Therefore, the spiral groove 221 can be installed on the guide protrusion 154 of the female joint portion 15 to be screw-fitted.

That is, the opening and closing control unit 20 forms a disk-shaped cap part 21 to narrow the gap (“a”) of the inclined surface 131 inside the flange unit 13 or to widen the gap (“a”). Adjustment can be made through the spiral groove 221 of one cross-shaped shaft blade 222.

In particular, the male shaft portion 22 has shaft wings 222 with spiral grooves 221 formed at their ends forming a cross shape radially from the central axis, and serves as a second airflow guide through which airflow passes between the shaft blades 222. “b” can be formed. The second airflow guideway “b”, together with the first airflow guideway “c”, can quickly and simultaneously discharge a large amount of polluted airflow such as indoor smoke.

When the distance "a" between the cap part 21 and the flange part 13 is set at the most effective distance, an efficient exhaust effect can be achieved according to the indoor airflow discharge method according to Bernoulli's theorem (a detailed explanation of Bernoulli's theorem will be described later). The explanation will be made using Figure 11, which introduces some drawings of the inventor's previously registered patent).

In this embodiment, when installed on a ceiling light, the male shaft portion 22 can be implemented in a cylindrical shape rather than a cross-shaped shaft blade 222. In the case of a cylindrical shape, the second airflow guide “b” is blocked and can be applied as an indoor ceiling ventilation opening.

The ring-shaped fastening portion 17 forms an inner periphery 173 with a small inner diameter and an outer outer periphery 174 that is ring-shaped and circular with a certain width. In order to fix the ventilation main body 10 to the ceiling, several fixing holes 171 are formed on the ring-shaped inner surface, and when installed, they correspond to the stopping protrusions 16 on the outer wall surface 11 of the ventilation main body 10. Several guide grooves 172 may be formed along the inner periphery 173 to guide the height in order to adjust the height.

Meanwhile, the ventilation main body 10 according to Example 1 of the present invention has at least two supports 152 across the first and second passages 141 and 142 inside the outer wall surface 11 in the transverse direction. A filter unit 153 can be formed between the supports 152 with relatively large diameter holes through which a plurality of airflows pass.

The filter member 153 of the ventilation device according to Example 1 of the present invention forms a plurality of micropores between the supports 152 or forms a separate filter material to prevent foreign matter in the airflow passing through the airflow passage 14. It performs a function of filtering, and the filter member 30 of Example 2 described below will be described on the premise that it is the same as the filter unit 153.

That is, as shown in FIGS. 4A to 5 of the accompanying drawings, the filter module 30 includes a filter unit 153 or a first filter 31 formed between the supports 152 by forming a plurality of micropores, and A second filter (32) made of non-woven fabric and installed below the first filter (31), a third filter (33) made of a deodorizing filter material and installed below the second filter (32), and a first filter (33) made of non-woven fabric and installed below the first filter (31). , The second and third filters (31, 32, and 33) are sequentially inserted and stacked on the airflow passage (13) and the lower part is finished, but a filter is installed between the supports (152) like the first filter (31). The finishing member 34 formed of material or made of open space can be tightened and fixed in various ways.

In embodiments of the present invention, a locking groove 341 may be formed on the edge side of the finishing member 34, and a locking protrusion 19 may be formed on the inner wall of the body portion 11 to allow it to be caught. The filters stacked on these filter modules 30 have through holes (symbols, not shown) formed at the center and are inserted and installed from below the female condensation portion 15, and the finishing member 34 is finished with a locking protrusion 19. A locking groove 341 can be formed so that it can be inserted and fixed. Of course, each filter member can be inserted one after another by forming a passage groove (not shown) so as to catch or penetrate the locking protrusion 19, but this is not shown in this embodiment.

Therefore, the indoor polluted airflow exhausted through the first passage 141 and the second passage 142 of the internal airflow passage 14 may be purified through the filter module 30 and then discharged, thereby not polluting the atmosphere. . The ventilation device according to this Example 1 can be installed on the ceiling to perform the function of an air purifying vent.

The ventilation device equipped with the filter module 30 can be implemented by changing the overall shape of the filter module 30 by arranging various materials made of freely deformable thin plates in regular or irregular wave shapes, and the filter module ( 30) Activated carbon particles can be deposited and applied to any one of them, and the activated carbon particles can be used to capture microorganisms contained in the moving air stream and absorb and deodorize bad odors.

Any one of each filter of the filter module 30 may be made of various shapes, including a cross waveform or a continuous waveform, and the material of the support 152 forming the first filter 31 is a thin aluminum plate material. It is suitable. Aluminum sheet material can form a highly flexible core and has excellent processing and formability, making it suitable as a filter core. In addition, copper can be processed into a thin plate and applied as the support member 152 core.

In the manufacture of the first filter 31 according to the present invention, the material such as aluminum, which becomes the support member 152, is first continuously formed into a strip-shaped thin plate, and then arranged in a regular or irregular wave shape, and the first filter is formed in the meantime. (31) can be manufactured in a variety of ways, such as spraying and coating activated carbon particles on the surface or impregnating activated carbon particles in a thin plate and drying them.

Activated carbon particles applied and deposited on the surface of any one of the multiple filters 31, 32, 33, and 34 of the filter module 30 have an excellent deodorizing effect on bad odors compared to other materials. When applied to air conditioning vents installed to maintain comfortable indoor air, it is effective in removing bad odors contained in indoor air, making it highly effective in maintaining comfortable indoor air.

In this Example 2, the names of the same symbols described in Example 1 are explained as separately as possible, but the same components are explained by applying the same symbols.

The ventilation device according to Example 2 of the present invention according to the drawings largely consists of a ventilation body 100, an opening/closing control unit 12, and a ring-shaped fastening member 17.

The ventilation main body 100 is further divided into a double body part 118, an expansion surface part 113, and a female condensation part 115.

The double body portion 118 is composed of a cylindrical outer body 1183 that is open at the top and bottom to form a sub-passage 1184 through which airflow passes, and an inner body 1181 that forms a main passage 1182. In the main passage 1182 and the sub passage 1184, the filter module 30 shown in FIGS. 4A to 5 of the first embodiment can be installed overlapping the main passage 1182. In addition, although not shown, filter bales 30 with larger internal diameters compared to the filter module 30 of FIG. 5 may be formed to overlap the sub-passages 1184 in the same manner. The filter module (30) applied here is made of a first filter (31) that has general porosity and filters out foreign substances such as pests and insects, and is made of non-woven fabric and is installed on the lower side of the first filter (31) to block viruses. A second filter (32), a third filter (33) made of deodorizing material and installed below the second filter (32), the first filter (31), the second filter (32), and the third filter (33). The filters 33 can be overlapped from below and an “L” shaped locking groove 341 is formed on the periphery of the filter to support them, and the filters 33 can be finished with a finishing member 34 forming a filter net made of metal wires that generate negative ions. there is.

The expansion surface portion 113 extends obliquely from the inner body 1182 to the front outer edge and forms a plurality of through holes 1133 of different sizes, and further forms an expansion edge (not shown) by bending the expansion surface 1132. After that, the flange 1131 can be formed.

The female condensation portion 115 forms a cylindrical axial tube portion 1151 with a narrow diameter at the center of the double body portion 118, and the axial tube portion 1151 has several radial support bars 1152. It can be formed across the inner wall of the main passage (1181) in a plate shape.

The support member 1152 may form a filter portion 1153 made of a porous filter therebetween, or the first filter 31 of the filter module 30 may be installed. The support member 1152 has this cylindrical shape. Inside the shaft tube portion 1151, guide protrusions 1154 are protruded at intervals in the spiral direction so that the spiral groove 221 formed on the shaft wing 222 of the male shaft portion 22 described above is screwed in the spiral direction. The length can be adjusted upwards. The ventilation main body 100 may form several locking protrusions 116 along the outer wall of the outer body 1183 in the longitudinal direction, and are inclined in the direction of insertion of the outer body 1183 and are formed to be caught in the direction of separation. As shown in FIG. 10, the ventilation main body 100 can be installed on the ceiling, exhaust duct, etc. using a ring-shaped fastening member 17, which will be described later.

The opening/closing control unit 12 can be divided into a cap unit 121 and a male shaft unit 122. The cap portion 121 is formed in a disk shape to open and close the gap "a" of the open end of the expanded surface portion 113, and the cap portion 121 is formed at a predetermined length at the inner center thereof.

The male shaft portion 122 extends a predetermined length from the center of the cap portion 121 to form a cross-shaped shaft blade 1222, and spiral grooves 1221 are formed in the spiral direction at the end of the shaft blade 222, and the shaft blade ( 1222) is formed to form a passage “b” for passing airflow.

The male shaft portion 122 has a spiral groove 1221 screw-fitted to the guide projection 1154 of the female shaft portion 15, and its height is adjusted according to its rotation.

The ring-shaped fastening member 17 is a fastening member that forms an inner edge 173 inside the ring-shaped space with a predetermined width and an outer edge 174 with a width, and is a fixing hole for fixing the ventilation main body 10 to the ceiling, etc. 171 is formed along its width, and several guide grooves 172 are formed in the inner edge 173 so that the above-described stopping protrusion 116 is caught and supported.

Therefore, the ring-shaped fastening member 17, which is installed on the ceiling and forms a through hole through the central inner edge 173 to fit the outer body 1183 of the ventilation main body 100, passes through the ring-shaped fastening member 17 to the ceiling, etc. to form the vent main body 10. The external body 1183 is installed through it. At this time, it is installed by adjusting the insertion depth in the guide groove 172 formed on the inner periphery 173 of the ring-shaped fastening member 17 by the locking protrusion 116.

In this embodiment 2, the body portion 111 includes an inner cylinder member (symbol omitted) consisting of an inner body 1181 forming the main passage 1182, as shown in FIGS. 8 and 9, and a sub passage (symbol omitted) outside the body portion 111. A double body 118 forming an inner and outer passage is formed by an outer cylindrical member (symbol omitted) consisting of an outer body 1183 forming 1184). This double body 118 is a second formed between the cross-shaped shaft blades 1222 in which the spiral groove 1221 of the male shaft portion 122 is formed as described above when exhausting the inner airflow to the outside through forced feeding when necessary. The first air stream "A1" of the air flow guide "b" flows together with the second air stream "A2" flowing through the main passage 1182 and the third air stream "A3" flowing through the sub passage 184, and a large amount of air flows quickly. The amount can be discharged at the same time. Of course, in contrast to this, the forced blowing unit 50 can be driven to drive the blower motor 53 in the opposite direction to suck in and exhaust the airflow in the room.

At this time, if the distance "a" between the cap portion 121 and the expansion surface portion 113 is set at a sufficient distance to achieve the best exhaust efficiency, the exhaust efficiency can become ideal. Sometimes, smoke and odors spread indoors can be powerfully discharged at the same time through the forced blowing unit 50, or the indoor air can be purified by forcibly blowing clean air from outside.

The ventilation main body 100 forms at least two supports 1152 horizontally across the main passage 1181, and between these supports 1152, holes of relatively large diameters through which a plurality of airflows pass are formed. The intrusion of pests such as mosquitoes can be prevented through the filter unit 1153.

The filter unit 1153 of the ventilation device according to Example 2 of the present invention forms a plurality of micropores between the supports 1152 and performs the function of filtering the airflow passing through the main passage 1181, as follows. It can be implemented with the first filter 31 of the filter module 30 of Example 2, and for convenience, the filter unit 1153 is used interchangeably with the same function.

The filter module 30 is made of a non-woven fabric and a first filter 31 that forms a plurality of micropores and forms a plurality of micropores between the support intervals 1152 or is in the form of a porous plate without the support interval 1152, and the first filter 31 is made of a non-woven fabric. A second filter (32) installed below the filter (31), a third filter (33) made of deodorizing material and installed below the second filter (32), the first filter (31), and the second filter (33). An "L" shaped catching groove 341 is formed on the edge side to support and finish the filter 32 and the third filter 33 from below, and can be laminated and assembled with a finishing member 34 that forms a predetermined porous filter network. Of course, although not shown, locking grooves (not shown) are formed on the edge of each filter (31, 32, and 33), pass through the locking protrusion (19) formed on the inner wall (symbol omitted), overlap, and then finish.

Among the attached drawings, Figure 9 is a cross-sectional view for explaining the operation of the ventilation device according to Example 2 of the present invention, and Figure 10 shows the structure of the ventilation device according to Example 2 of the present invention by connecting a forced blowing unit in case of emergency. It is a schematic diagram, and Figure 11 is a diagram to explain the flow amount of internal and external air currents according to Bernoulli's theorem, citing a conventional patent.

According to the above drawings, the airflow exhaust action in the case where rapid forced exhaustion of indoor polluted air, etc. is required according to Example 2 of the present invention will be described.

In Figure 10, the blowing unit 50 can be installed to exhaust air through a switching means (not shown). That is, the connecting member 51 connected to the rear end of the ventilation main body 10 (110) of Examples 1 and 2, the blowing fan 52 connected to the rear end of the connecting member 51, and the blowing fan 52 are driven. It may be composed of a driving motor 53 that operates. As described above, a flexible connecting member 51 such as a hose that can be selected to fit the diameter of the inner body 1181 or the outer body 1183 on which the filter module 30 of this embodiment 2 is installed is connected. This allows the internal airflow to be forcibly exhausted.

The forced blowing unit 50 connects the insertion hole (not shown) of the connecting member 51 connected to the blowing fan 52 and the drive motor 53 to the rear end of the inner body 1181 to forcefully blow the contaminated airflow inside. At the same time, it is possible to suck out nearby contaminated air through the external body 1183. This can be explained according to the principle of Bernoulli's theorem, which will be described later, and at the same time, depending on the gap ("a") of the cap portion 121, the external airflow can be sucked out. Depending on the inhalation, an air current described later may be discharged.

That is, with respect to the airflow movement of the ventilation device (10) (100) according to the embodiment of the present invention, FIG. Let's look at this for reference.

That is, when passing through the neck (b), the passing speed of the airflow in the neck (b) increases and the pressure decreases according to [Equation 1] and [Equation 2] (Bernoulli's equation) below.

[Equation 1]

[Equation 2]

When the gap ("a") between the external air passage and the external air guide member according to the above [Equations 1 and 2] between the outer cover member and the external air guide member is 7 cm, the diameter of the venturi pipe neck (b) is 2.2 to 2.8 cm. It is desirable. That is, in general, the hourly exhaust volume of a ventilation device using outside air is set to 120 (liters) as the fluid volume, the passing air flow rate (fluid volume) is set to 2.0 (liters) per minute, and the inner diameter of the vertical exhaust passage is set to 7.0 cm. At this time, the actual measurement result of the passing pressure (P1) was 0.36kgf/cm2, and the flow speed was 0.80 to 0.9 m per second, which was consistent with 0.86 calculated by the formula below.

That is, V1=Q/A1=[0.000033㎥/s]÷[(0.007m) ² (π/4)]=0.86m/s

Here, V1 represents the flow rate per second (m/s) at the passage inlet (a) of the outside air, Q represents the amount of passing gas (㎥/s), and A ₁ is the gap between the inlet and outlet of the outside air passage (a). It represents the cross-sectional area (㎡). When the distance (a) between the external cylinder and the inlet and outlet is fixed at 7.0 cm, and the pipe diameter (D ₂ ) of the middle neck (b) is changed to 2.0 cm, 2.5 cm, and 3.0 cm, the flow velocity in the neck (b) is V ₂ ) and the pressure inside the pipe (P ₂ ) were calculated by the following [Equation 3] (Bernoulli's equation), and the results are shown in Table 1.

[Equation 3]

In the above equation, P ₁ represents the passing pressure of the outside air at the passage inlet (a), P ₂ represents the pressure inside the throat (b), ρ is the density of the gas (1,000 kg/㎥), and V ₁ is the inlet/outlet gap. This is the flow rate in (a), and V ₂ represents the flow rate in the neck (b).

Table 1

As shown in Table 1 above, as the pipe diameter of the neck (b) becomes narrower, the flow rate in the neck (b) becomes the square of the ratio of the pipe diameter of the neck (b) to the pipe diameter of the external air passage and the inlet and outlet gap (a). It was proportional to the reciprocal, and the pressure inside the pipe at the neck (b) increased by more than 1.5 times the increase rate of the pipe diameter as the pipe diameter increased. When the pipe diameter of the neck portion (b) is set to 2.0 cm, the pressure inside the pipe becomes negative, and as a result, the exhaust volume of the exhaust passage can reach the neck portion (b) along the exhaust passage in an uncontrolled state. The spacing (c) of the exhaust passage is divided into two sides on the drawing, but in reality, it was calculated as the passage area excluding the area of the long axis located at the center. Therefore, when the distance between the external air cylinder and the inlet and outlet parts (a) between the outer cover member and the external air guide member is 7 cm, the diameter of the venturi pipe neck (b) is preferably 2.2 to 2.8 cm, and is within this range. Controllable and preferably, the diameter of the Venturi tube neck (a) is 2.5 cm. As schematically compared in the cross-sectional views along the lines ㄱ-ㄱ', ㄴ-ㄴ', and ㄷ-ㄷ' of Figure 8a in the attached drawing of the previously registered patent No. 10-1865613, the gap (a) between the external cylinder and the inlet and outlet is 7cm. In this case, it is best that the diameter of the venturi pipe neck (b) is 2.5 cm, and the diameter of the exhaust passage 31 is preferably 1.0 cm.

That is, it can be seen that the ratio of the inlet and outlet spacing (a):throat spacing (b):exhaust passage (c) is 7.0:2.2 to 2.8:1.0.

When the distance (a) between the external air passage inlet and outlet between the outer cover member and the external air guide member according to [Equations 1, 2, 3] and {Table 1} analyzed in the previously registered patent 10-1865613 is 7cm, the venturi The pipe diameter of the pipe neck is preferably 2.2 to 2.8 cm. That is, in general, the exhaust volume per hour of a ventilation device using outside air is set to 120 (liters) as the fluid volume, the passing airflow volume (fluid volume) is set to 2.0 (liters) per minute, and the inner diameter of the vertical exhaust passage is set to 7.0 cm. At this time, the actual measurement result of the passing pressure (P1) was 0.36 kgf/cm2, and the flow speed was 0.80 to 0.9 m per second, which was consistent with the calculated 0.86. In this way, when the distance (a) between the external cylinder and the inlet and outlet is 7cm, it is best that the diameter of the venturi pipe neck (b) is 2.5cm, and the diameter of the exhaust passage is 1.0cm. That is, it can be seen that the ratio of the inlet and outlet spacing:neck spacing:exhaust passage is 7.0:2.2 to 2.8:1.0.

Among the attached drawings, Figure 9 is a cross-sectional view illustrating the airflow flow action of the ventilation device according to Example 2 of the present invention, and Figure 10 shows the structure of the ventilation device according to Example 2 of the present invention by connecting a forced blowing unit in case of emergency. This is a schematic diagram.

As shown in these drawings, Embodiment 2 of the present invention provides a structure for instantaneous and rapid discharge of indoor airflow.

In general, indoor air exhaust devices and ventilation devices have a common structure that makes up the vent, and even though the gap between the cap parts is adjustable, the indoor air discharge width is limited and the amount of moving air is reduced, so the function cannot be implemented.

As explained through Examples 1 and 2, the ventilator device of the present invention is simple to assemble and separate between parts, so installation of the vent is easy and installation time can be reduced. In addition, it has the effect of being conveniently installed even if you are not a construction expert. there is.

The ventilation vent of the present invention is provided with a filter inside the ventilation main body, and contaminants such as (ultra) fine dust or foreign matter in the air that passes through the duct and flows into the main body are filtered by the filter to supply clean air into the room. You can.

It is a non-powered indoor airflow exhaust device that discharges indoor airflow by the external wind of the building. It prevents air from flowing back from the outside to the inside, ensuring efficient ventilation, and also prevents rainwater from flowing back from the outside. , it is possible to provide a non-powered ventilation device that allows the inlet and outlet airflow passage areas to be adjusted to suit the high and low floors of a building or highlands in proportion to the strength of the wind applied to the exterior wall.
