Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for a ventilation opening covering a ventilation opening such as a range hood and a ventilation fan, a cover member for a ventilation opening useful for preventing contamination of the ventilation opening, and a cover for the ventilation opening to the ventilation opening. Regarding the installation method.

[0002]

2. Description of the Related Art Conventionally, a ventilation opening such as a range hood or a ventilation fan sucks dirty air in a room or oil smoke generated in a kitchen and discharges it out of the room. . Also, due to the inflow of dust and foreign matter,
The fan may be damaged or the motor load may increase. Therefore, a ventilation fan cover having a filter made of non-woven fabric or the like is attached to the ventilation port. However, since the ventilation port is usually installed at a high position in the room, the filter installation work is complicated. In addition, the ventilation port to which the ventilation fan is attached is set to various sizes according to the volume of the ventilation section, the ventilation volume, etc., in order to perform efficient ventilation.

In view of the above points, Japanese Utility Model Laid-Open No. 3-10136 discloses a filter and a peripheral portion of the filter.
Further, there is disclosed a ventilating fan cover having a cord-shaped body capable of contracting the peripheral portion. According to this ventilation fan cover, since the cord-shaped body capable of contracting the peripheral portion is provided at the peripheral portion of the filter, the ventilation fan is capped with the ventilation fan cover to fasten the cord-shaped body or the cord-shaped body. By forming the body with a stretchable material, the ventilation fan cover can be easily attached even if the size of the ventilation fan is different. However, this ventilation fan cover is still not sufficient in terms of versatility and practicality.

For example, in a ventilation opening formed in a frame such as a ventilation fan or a range hood, a gap is often formed at a corner between a wall and a frame provided on the wall. In such a ventilation opening, even if the ventilation opening is covered with a ventilation fan cover having a string-like body at the edge of the filter and the filter is contracted and attached on the side surface of the frame, the gap cannot be covered by the filter. Therefore, dirty air in the room enters the ventilation opening through the gap and is discharged to the outside by the fan, so that the inside of the frame and the fan are easily contaminated. Further, in the ventilation fan cover, wrinkles may occur in the contraction portion of the filter due to the string-like body, and a non-contact portion (gap) may be formed between the filter and the filter mounting surface such as the frame body. In such a case, dirty air invades from the non-contact portion, and the outer surface of the frame body is contaminated.

Further, in the ventilation port formed in the frame, not only the size of the ventilation port but also the depth of the side surface of the frame is various. Therefore, in the ventilating fan cover, in the case of a thin ventilating fan or the like, when the cord-like body is contracted by the side surface of the frame body, there is a case in which a margin portion is formed in the front surface of the ventilation port, and the filter cannot be tightly mounted. On the contrary, when it is attached to a ventilation fan having a large depth, the side surface of the frame cannot be completely covered, and the entire surface of the frame cannot be prevented from being soiled. Further, when the frame is attached to a ventilation fan or the like in which a convex portion such as an oil pot is formed on the side surface, the convex portion cannot be covered and the convex portion is easily contaminated.

Further, in the above ventilation fan cover, if it is used for a ventilation port having a fan having a large suction force, displacement and suction of the ventilation fan cover cannot be sufficiently suppressed only by the elastic cord-like body, and the ventilation fan cover comes off. There is a risk.

On the other hand, in Japanese Patent Laid-Open No. 4-131113, a non-woven fabric is used as a filter member, and engaging means for engaging with the non-woven fabric in advance, for example, a base provided with hook-like projections, and a large number of hook-like shapes on the surface. Attach a sheet fastener provided with objects around the exhaust port, cover the exhaust port with the non-woven fabric,
A method of mounting a filter member to an exhaust port, which temporarily fixes the peripheral portion of the nonwoven fabric to the engaging means, is disclosed. However, even in the method using the substrate provided with the hook-shaped projections, the operation and stop of the fan at the exhaust port are repeated,
When the amount of air passing through the ventilation port (ventilation amount) fluctuates, the filter and the hook-shaped projection become loose, and the filter moves along the hook-shaped projection and disengages from the tip of the hook-shaped projection. There is. The same thing can happen when the fiber density of the filter member is low. Further, in the method of fixing the filter member with the sheet fastener, there are cases in which the filter member cannot be reliably fixed because of low engagement with the filter member due to the fiber diameter, fiber density, surface condition, and the like of the filter member.

Regarding the method of attaching the filter to the range hood, the above-mentioned Japanese Patent Laid-Open No. 4-131113 discloses
A method of mounting a filter is disclosed in which the exhaust port is covered with a sheet-shaped filter member wider than the exhaust port such as a range hood, and the periphery of the filter member is pressed and fixed by a magnet holder. However, since the size of the ventilation opening of the range hood also varies depending on the product, this method requires that the range hood of different sizes be handled.
It is necessary to prepare a filter suitable for each range hood. Further, in this method, it is necessary to dispose a plurality of magnet holders while supporting the filter covering the exhaust port, so that the filter mounting work is complicated.

[0009]

Another object of the present invention is to provide a ventilation port cover which can remarkably suppress contamination in the frame and the ventilation port, and a method for mounting the same.

Another object of the present invention is to provide a ventilation port cover which can be easily and tightly attached even when the size of the ventilation port or the frame is different to some extent and which can prevent the entire surface of the frame from being soiled. To do.

Another object of the present invention is to provide a method capable of surely attaching the ventilation port cover to the range hood by a simple operation even if the ventilation ports have different sizes.

Further, another object of the present invention is to provide a ventilation in which a ventilation port cover can be reliably and stably fixed to the ventilation port for a long period of time regardless of the magnitude of the suction force of the fan of the ventilation port or the fluctuation of the ventilation amount. An object of the present invention is to provide a method for attaching a mouth cover member and a ventilation port cover.

[0014]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by a ventilation port cover having a filter having a band-shaped portion formed at the peripheral edge thereof and a cord-shaped member capable of contracting the peripheral edge of the filter. To do.

According to this ventilation port cover, since the cord-shaped body capable of contracting the peripheral portion of the filter is provided, the ventilation port is capped with the ventilation port cover and the cord-shaped body is fastened. By forming the string-like body with a stretchable material, the ventilation port cover can be easily attached even if the ventilation port has a different size. Further, since the band-shaped portion is formed in the peripheral portion of the filter, even if there is a gap in the corner portion between the frame of the ventilation port and the wall, the band-shaped portion should be along the wall or inserted into the gap. With this, since the gap can be covered, it is possible to prevent dirty air from entering the ventilation port from the gap and contaminating the inside of the frame and the fan. Further, even if a non-contact portion (gap) is formed between the contraction portion of the filter due to the string-like body and the filter mounting surface of the frame body, since the gap can be covered by the band-shaped portion of the filter peripheral portion, it is possible to prevent contamination. It is possible to prevent the fresh air from directly entering through the gap and contaminating the outer surface of the frame body.

Further, since the belt-shaped portion is formed, when the side surface of the frame body has a small depth, the belt-shaped portion is folded inward or along the wall so that the front surface of the ventilation port is Can be installed tightly without creating a margin. On the other hand, even if the depth of the side surface of the frame is large to some extent, since the entire side surface of the frame can be covered with the strip portion, the entire surface of the frame can be protected from contamination by oily smoke or the like. Furthermore, even if a convex portion such as an oil pot is formed on the side surface of the frame body, the convex portion can be prevented from being contaminated by coating the convex portion with a belt-shaped portion.

The present invention is also a method of attaching the above-mentioned ventilation port cover to a ventilation port formed in a frame body provided on a wall, in which the ventilation port is covered with the ventilation port cover and the filter is provided on the side surface of the frame body. The above-mentioned problem is solved by a method of attaching a ventilation port cover that contracts with a belt-shaped portion and covers the corner portion between the wall and the frame.

According to this mounting method, since the filter is covered with the ventilation hole cover having the band-shaped portion formed on the periphery thereof and the peripheral portion of the filter is contracted by the cord-like body, the size of the ventilation hole is increased as described above. Ventilation cover can be easily installed even when the ventilation cover is different. Further, since the corner portion between the wall and the frame is covered with the belt-shaped portion of the ventilation port cover, it is possible to prevent dirty air from entering the ventilation port through the gap between the corner portions, and it is possible to remarkably suppress the contamination in the ventilation port. .

Furthermore, the present invention relates to a method for attaching a ventilation port cover to a range hood, wherein the ventilation port of the range hood is covered with a ventilation port cover having a cord-like body capable of contracting the peripheral portion of the filter. The above problem is solved by a method of attaching the ventilation port cover to the range hood, in which the filter is contracted by the cord-like body and the ventilation port cover is locked to the range hood main body.

According to this method, since the ventilation port cover has the string-like body capable of contracting the peripheral portion of the filter, the ventilation port is covered with the ventilation port cover even if the size of the range hood body is different. The ventilation port cover can be securely attached by a simple operation of crowning and contracting the filter with a string-shaped body.

Further, the present invention is a cover member for a ventilation port formed in a frame body, the cover for the ventilation port having a contractible cord-like body at the peripheral edge of the filter, and attached to the side surface of the frame body. The above-mentioned problem is solved by a ventilation port cover member including a locking member capable of locking the peripheral edge portion of the filter of the ventilation port cover.

According to this ventilation port cover member, the hook member is attached to the side surface of the frame body, the ventilation port is covered with the ventilation port cover, and the peripheral portion of the filter is contracted with the string-shaped body.
The ventilation port cover can be attached by a simple operation of hooking the peripheral portion of the filter to the hook member. The movement of the filter in the direction parallel to the filter mounting surface can be restricted mainly by the latching member, and the movement of the filter in the direction perpendicular to the filter mounting surface can be restricted mainly by the fastening force of the string-shaped body. . Therefore, it is possible to surely prevent the filter from being displaced due to the suction force of the fan of the ventilation port by the hooking member, and the filter is detached from the tip of the hooking member due to the contraction action of the filter peripheral portion by the string-shaped body. Can be prevented. Therefore, even if the ventilation port has a strong suction force of the fan, even if the fan is repeatedly operated and stopped, the ventilation volume fluctuates, and even if the filter fiber density is not very high, The mouth cover can be prevented from being sucked in or removed, and the ventilation port cover can be stably fixed to the ventilation port for a long period of time.

Further, the present invention is a method of attaching a cover for a ventilation opening having a cord-like body which can be contracted to the peripheral edge of the filter to the ventilation opening formed on the frame,
A hooking member capable of hooking the filter is attached, the ventilation opening is covered with the ventilation opening cover, the peripheral edge of the filter is contracted by the string-like body, and the peripheral edge of the filter is hooked on the locking member. The above-mentioned problem is solved by a method of attaching the cover for the ventilation port to the ventilation port.

According to this mounting method, since the peripheral edge of the filter of the ventilation port cover is contracted by the string-like member and the peripheral edge of the filter is hooked by the hooking member, as described above, The cover for the ventilation port can be stably fixed to the ventilation port for a long period of time regardless of the magnitude of the suction force of the fan and the fluctuation of the ventilation amount.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that, for convenience of explanation, the same members and parts are designated by the same reference numerals.

FIG. 1 is a perspective view showing an embodiment of a ventilation port cover of the present invention, FIG. 2 is a perspective view showing a state in which the ventilation port cover of FIG. 1 is attached to a ventilation fan, and FIG. FIG. FIG. 4 is a longitudinal sectional view of a main part showing another state in which the ventilation port cover of FIG. 1 is attached to a ventilation fan.

The ventilation port cover 1 has a filter 2 and an elastic cord-like body 3 provided on the peripheral portion of the filter 2. More specifically, in the filter 2, the peripheral portion is bent inward over the entire periphery, leaving the central portion, and the opening 5
Is formed in a bag shape. The filter 2 may be made of a material having air permeability, but is preferably made of a flame-retardant non-woven fabric. As the flame-retardant nonwoven fabric, various materials can be used, but it is preferable that polyvinyl chloride is formed of a flame-retardant fiber having a fibril shape in a polyvinyl alcohol matrix and a reinforcing fiber, for example, a polyester fiber. . The thickness of the fibers forming the non-woven fabric can be appropriately selected in consideration of the strength and air permeability of the filter. The thickness of the fibers is, for example, about 2 to 20 denier, and is often 10 denier or less (for example, about 5 to 10 denier). Further, the central portion of the filter 2 forms a flat surface portion 2a which is flush with the ventilation port in order to prevent a marginal portion such as a corrugated shape or a mountain shape from being generated in the attachment state.

An annular insertion hole 4 is formed inward of the edge of the opening 5 in the filter 2, and an annular strip 6 is formed between the annular insertion hole 4 and the edge. ing. The annular insertion hole 4 is provided with an annular cord-like body 3 which is shorter than the length of the annular insertion hole 4 and has a stretchable material, for example, synthetic rubber. The annular insertion hole 4
Can be formed by suturing a cloth piece or the like capable of forming an annular insertion hole to the filter, or by fixing an annular member having an insertion hole to the filter 2. The contraction rate of the string 3 can be selected within a range in which the function of locking the filter to the frame body or the like is not impaired, and is, for example, about 5 to 60%. Here, the contraction rate (r (%)) of the cord-like body is defined as L1 which is the length of the cord-like body when no external force is applied, and L2 which is the maximum length when the cord-like body is extended. R = (L1 / L2)
It means a value of × 100.

A ventilation fan having a fan 10 and a frame 7 surrounding the fan 10 is provided on the wall 13. Further, since the frame body 7 supports the ventilation port cover,
A cover support having a frame 8 having a size adapted to the above and a strip-shaped frame portion 9 extending from the frame 8 in the vertical and horizontal directions in a bridge shape is attached. Further, there is a gap 12 at the corner between the wall 13 and the frame body 7.
Communicates with the exhaust port 11.

The ventilation port cover 1 can be attached to the ventilation port 11 of the ventilation fan as follows. That is, the cord-like body 3 of the ventilation port cover 1 is extended, and the cover 1 and the frame body 7 are capped with the ventilation port cover 1. Then, the extension of the string-like body 3 is released on the side surface of the frame body 7, and the strip-shaped portion 6 of the filter 2 is arranged along the wall 13 as shown in FIG. Cover the corner with the body 7. Further, as shown in FIG. 4, by inserting the strip-shaped portion 6 into the gap 12, the corner portion can be covered with the strip-shaped portion 6.

According to the ventilation port cover 1, since the cord-like body 3 having elasticity is used, even if the size of the ventilation port is different, a simple operation of extending the string-like body 3 and releasing it. Can be attached to the ventilation port by operation. Further, since the cord-like body 3 is provided inward of the end portion of the peripheral portion of the filter 2, and the band-like portion 6 is formed between the end portion of the filter 2 and the cord-like body 3, the wall is formed. Even if the gap 12 exists at the corner between the frame 13 and the frame body 7, the strip-shaped portion 6 is arranged along the wall 13 as shown in FIG. 3, or as shown in FIG. The strip-shaped portion 6 can cover the corner portion by inserting it into the. Therefore, it is possible to prevent the dirty air from entering the ventilation port through the gap 12 at the corner portion and contaminating the inner surface of the frame body 7, the fan, the inner wall of the exhaust port, and the like.

Further, as shown in FIG. 3, when the depth of the side surface of the frame body 7 is small, the frame body 7 of the strip-shaped portion 6 is formed.
By covering the side surfaces of the frame 7 with the remaining portion that is still left along the wall surface of the wall 13 or by folding the remaining portion inward, a margin portion is generated in the front surface of the ventilation port while covering the entire frame body 7. The cover for the ventilation port can be installed tightly without having to do so. On the other hand, even if the depth of the side surface of the frame body 7 is somewhat larger than that of the frame body shown in FIG. 3, the remaining portion of the strip-shaped portion 6 can be compensated for by the increased depth, so that the entire frame body 7 can be covered. Thus, according to the ventilation cover,
Even if the depth of the side surface of the frame is different to some extent, the frame can be mounted tightly and the entire surface of the frame can be covered, so that the contamination of the entire frame can be prevented.

Further, even if the contraction portion of the filter 2 due to the string-like body 3 does not completely contact the side surface of the frame body 7 and a gap is formed between the two, the band-like portion 6 at the peripheral portion of the filter covers the gap. Therefore, it is possible to prevent dirty air from directly entering through the gap and contaminating the outer surface of the frame body 7. Further, even if a convex portion such as an oil pot is formed on the side surface of the frame body, the convex portion can be covered with the belt-shaped portion 6, so that the convex portion can be prevented from being soiled and the appearance is excellent.

The central portion of the filter 2 does not need to form a flat surface which is completely flush with each other in the mounted state.
An extra portion such as a corrugated part may be formed in a range that can suppress suction to the ventilation port without spoiling the aesthetic appearance.

Further, the elastic cord-like body 3 does not need to be arranged in a state of being housed in the annular insertion hole 4, and an end portion of the peripheral portion of the ventilation port cover 1 can be formed by an appropriate means such as stitching. It may be provided more inwardly, at least partially integrally. When the string-like body 3 is partially provided inward from the end of the peripheral portion of the ventilation port cover, the band-like portion is partially formed at the peripheral portion of the filter. In addition, the string-shaped body is not limited to a stretchable material, and may be formed of a non-stretchable material. That is, an opening may be provided in the annular insertion hole 4, and the string-shaped body may be inserted into the insertion hole in a state where both ends of the string-shaped body are pulled out from the opening. In this case, the ventilation port cover can be easily attached by fastening both ends of the string-shaped body with the ventilation port covered with the ventilation port cover.

The band-shaped portion 6 has flexibility so that it can be fitted tightly to the surface of the frame or the wall, and has strength enough to maintain the attached state without being disturbed or broken by the wind during ventilation. Just do it. For example, the band-shaped portion 6 may be formed of a plastic film or sheet having no air permeability in addition to the materials described as the material forming the filter. The width of the belt-shaped portion 6 can be selected within a range that does not impair the wearing property of the ventilation port cover, for example, about 0.5 to 10 cm,
Preferably about 1 to 6 cm, more preferably 1.5 to
It is about 4 cm.

When the peripheral portion of the filter 2 of the ventilation port cover 1 is contracted by the cord-like body 3, a fold (crease) is usually formed on the band-shaped portion 6 due to the contraction. for that reason,
Depending on the width of the strip-shaped portion 6 and the like, there may be a gap between the frame and the wall at the edge of the strip-shaped portion 6. In order to prevent the formation of this gap, the band-like portion 6 may be provided with a fold line extending from the inner side to the outer side, preferably, a fold line extending outwardly. Further, a reinforcing material such as a reinforcing tape may be provided between the folds in the outer peripheral edge of the band-shaped portion. A plastic film or sheet can be used as the reinforcing material. In such a ventilation port cover, since the gap is absorbed by the fold lines, the adhesion between the strip portion and the frame body or the wall is improved, and dirty air is prevented from entering through the gap of the fold portion. It can be prevented. Therefore, it is possible to reliably prevent the surface of the frame and the ventilation port from being contaminated.

The ventilation port cover of the present invention can be attached to the ventilation fan whose front surface is not shielded through the cover support as described above, and the front surface is shielded by the support frame or the like. It can be attached to the existing ventilation fan as it is without using the cover support. Further, it is not limited to the ventilation fan and can be suitably used for other ventilation openings such as a range hood.

FIG. 5 is a perspective view showing a state in which the ventilation port cover of the present invention is attached to the range hood.

The ventilation port cover 14 is formed in the same manner as described above. That is, the ventilation port cover 14 has the filter 15 and the elastic string-like body 16 provided on the peripheral edge of the filter 15, and the space between the end of the filter 15 and the string-like body 16 is provided. The band-shaped portion 17 is formed. Further, in this range hood, a ventilation port 20 is formed on the lower surface of the range hood body 18.

The ventilation port cover 14 can be attached to the range hood as follows. That is, the cord 16 of the ventilation port cover 14 is expanded to
Cover. Then, the extension of the string-like body 16 is released to contract the filter 15 and the filter 15 is locked to the side surface 19 of the range hood main body 18 (frame body) so that the range hood can be attached to the range hood.

In this mounting method, the ventilation port cover 14 is used.
Has a cord-like body 16 capable of contracting the peripheral edge of the filter 15, so even for range hoods having different sizes of the ventilation openings 20, a simple operation of extending the cord-like body 16 and releasing the cord-like body can surely be performed. Can be installed on. Further, since the cord-like body 16 is provided inward of the end of the filter 15 and the band-like portion 17 is formed on the peripheral edge of the filter 15, the contraction portion of the filter 15 due to the cord-like body 16 is the range hood body. Even if the side surface 19 of the filter 18 does not completely adhere to the side surface of the range hood body 18 and a gap is formed between the string-like body 16 and the side surface of the range hood body 18, the band-shaped portion 17 of the filter peripheral edge adheres to the side surface of the range hood body 18. Since the gap is covered, dirty air can be prevented from directly entering through the gap and contaminating the side surface of the range hood body 18.

When the cover for the ventilation port is attached to the range hood, it is sufficient that the cover for the ventilation port has a cord-like body capable of contracting the peripheral portion of the filter, and the band-shaped portion is not necessarily formed on the peripheral portion of the filter. It does not have to be done. Even such a ventilation port cover can be easily and reliably attached to a wide range hood having different ventilation port sizes. Further, the above mounting method is not limited to the shallow range hood as shown in FIG. 5, but can be suitably applied to a deep range hood.

FIG. 6 is a perspective view showing an example of a ventilation port cover in the ventilation port cover member of the present invention, and FIG. 7 is a perspective view showing an example of a hook member in the ventilation port cover member of the present invention. 6 is a perspective view showing a state in which the ventilation port cover of FIG. 6 is attached to the ventilation port by using the hooking member of FIG. 7, and FIG. 9 is a vertical cross-sectional view of FIG.

The ventilation port cover 21 has a stretchable cord-like body 23 around the periphery of the filter 22. More specifically,
The filter 22 is formed into a bag-like shape having an opening 25, with the peripheral portion of the filter 22 being bent inward over the entire circumference, leaving the central portion.

The filter 22 is made of the same material as the filter 2, and the central portion of the filter 22 forms a flat portion 22a in the mounted state. An annular insertion hole 24 is formed at the edge of the opening 25 of the filter 22. The annular insertion hole 24 can be formed by sewing the edge portion of the filter 22 or attaching a separately prepared member having an insertion hole to the edge portion of the filter 22 by fixing or the like. An annular stretchable cord-like body 23 similar to the above is arranged in the annular insertion hole 24.

The latching member 26 is composed of a substrate 27 and a tooth-shaped projection piece 28 provided at the end of one surface of the substrate 27. The angle of the protrusion 28 with respect to the substrate 27 is 8
It is about 0 °. The protrusion piece 28 is composed of a plate-shaped base portion and a tip portion in which a plurality of protrusions extending from the base portion are arranged in parallel, and the tip of each of the protrusions forms an acute angle. The length of the protrusion is larger than the thickness of the filter 22. Then, an adhesive tape (not shown) having an adhesive layer on the front surface is attached to the back surface side of the substrate 27 (the surface opposite to the surface on which the protruding pieces are formed).

Any material can be used as the material for forming the hooking member 26 as long as it can secure the strength with which the filter 22 can be hooked, and examples thereof include metals and plastics.
The substrate 27 and the protruding piece 28 of the latch member 26 may be made of the same material or different materials.

The wall 33 is provided with a fan 34 and a frame 29 surrounding the fan 34. A large number of slits 32 that allow air to pass through are provided on the front surface 31 of the frame body 29.
A ventilation port 35 is formed.

The ventilation port cover 21 can be attached to the ventilation port 35 as follows. That is, the plurality of hook members 26 are fixed to the side surface 30 of the frame body 29 at appropriate intervals. More specifically, when the ventilation port cover 21 is attached to the ventilation port 35, the protruding piece 28
The parallel direction of the protrusions is orthogonal to the direction in which the suction force of the fan 34 acts on the filter 22, and the inclination direction of the protrusion piece 28 is the direction in which the suction force of the fan 34 acts on the filter 22. The locking member 26 is arranged on the side surface 30 of the frame 29 so as to be in the opposite direction, and is fixed by the adhesive tape.

Then, the cord-like body 23 of the ventilation port cover 21 is extended to cover the ventilation port 35 with the ventilation port cover 21. Then, the extension of the string-like body 23 is released, and the inside of the string-like body 23 of the filter 22 is passed through the projection body of the projecting piece 28 of the locking member 26, and the string-like body 23 is projected.
It is brought into contact with the wall surface on the outer side (the edge side of the filter 22) of the base portion of.

According to this mounting method, the filter 22
Is locked by the projection of the projection piece 28 of the locking member 26, and the peripheral edge of the filter 22 is contracted by the elastic force of the elastic cord 23, so that the filter 22 is parallel to the filter mounting surface. The movement of the filter 22 can be regulated by the hooking member 26, and the movement of the filter 22 in the direction perpendicular to the filter mounting surface can be regulated by the expansion and contraction force of the cord 23. Therefore, even if the suction force of the fan 34 is strong and the filter 22 is displaced or is sucked into the ventilation port 35 only by the stretching force of the string-like body 23, the retaining member 26 causes the filter 22 to be displaced in the parallel direction. Can be reliably prevented. On the other hand, when the fan 34 is repeatedly operated and stopped or the ventilation amount is changed, when the ventilation amount changes abruptly due to the outdoor wind, when the fiber density of the filter 22 is small, and the like, only the locking member 26 is used as a filter. Even when 22 disengages from the hooking member 26 and the ventilation port cover 21 is easily detached, the vertical movement of the filter 22 is restricted by the expansion and contraction force of the string-like member 23, so the hooking member 26 It is possible to prevent the filter 22 from being detached. As described above, in the above-described mounting method, the peripheral portion of the filter 22 is contracted by the cord-like body 23, and the filter 22 is hooked on the hooking member 26. Therefore, the cord-like body 23 and the hooking member 2 are attached.
It is possible to eliminate the drawbacks when using 6 individually, and to fully exhibit the original functions of the string-like body 23 and the hooking member 26. Therefore, the ventilation port cover 21 can be reliably fixed to the ventilation port 35 and stably for a long period of time.

Further, in this example, since the elastic cord-like body 23 is used, the peripheral portion of the filter 22 can be contracted by a simple operation of extending the cord-like body 23 and releasing it. It is extremely easy to attach and detach the cover 21 for use.

Further, the tooth-shaped projection piece 28 of the latch member 26 is provided.
Then, since the plurality of protrusions are closely arranged in parallel at the tip portion, the filter retaining ability can be remarkably enhanced. In addition, the fan 3 in which the projection of the projection piece 28 acts on the filter 22
Since they are juxtaposed in a direction orthogonal to the direction of the suction force of 4, the hooking function of each projection can be reliably exerted, and suction and displacement of the ventilation port cover 21 can be remarkably prevented. Moreover, since the tip of the protrusion of the protrusion 28 is formed at an acute angle, the filter 22 can be easily penetrated. Further, since the length of the protrusion is formed to be larger than the thickness of the filter 22 and the protrusion piece 28 is inclined to the side opposite to the direction of the suction force of the fan 34, the filter 22 is a hook member. It is hard to come off from 26.

In addition, the inside of the cord-like body 23 of the filter 22 is passed through the protrusion of the hooking member 26 so that the cord-like body 23
Is brought into contact with the outer wall surface (on the side of the edge of the filter 22) of the projection piece 28 so that the string-like body 23 itself can be restricted from moving by the projection piece 28 and the tooth-like shape of the filter 22. Detachment from the projection can be reliably prevented by the elastic force of the string-like body 23. Therefore, the cord-like body 23 and the hooking member 26 function reliably, and the ventilation port cover 21 can be firmly fixed.

The filter 22 of the ventilation port cover 21
Similarly to the above, it is not necessary for the central portion of the above to form a completely flush plane portion in the mounted state. Further, the stretchable string-like body 23 may be provided at least partially integrally with the peripheral portion of the filter 22 by an appropriate means such as stitching. Also,
The string-like body may be formed of a non-stretchable material as described above.

Further, the ventilation port cover is not limited to the above,
For example, it may be a cover having a filter having a band-shaped body formed on the peripheral edge thereof and a string-shaped body capable of contracting the peripheral edge of the filter like the ventilation port cover 1. When such a ventilation port cover is used, the entire belt 27 of the hooking member 26 can be covered by the belt-shaped body at the peripheral portion, so that it is possible to prevent a gap from being formed on the side portion of the substrate 27 in the attached state. . Therefore, it is possible to reliably prevent the surface of the frame body 29 from being contaminated.

Furthermore, the angle of the projection piece 28 (or the projection at the tip of the projection piece 28) with respect to the substrate 27 is not limited to the above, and can be set within a range that does not impair the filter locking function,
For example, 30 ° to 150 °, preferably 45 ° to 135
And more preferably about 60 ° to 120 °. In order to enhance the filter retaining function, it is preferable that the protrusion piece 28 is inclined in a direction orthogonal to the parallel direction of the protrusions, for example, 5 ° or more, preferably 10 ° or more. The tip of the protrusion of the hooking member 26 does not have to have an acute angle, and may have any shape as long as it can penetrate the filter 22. Further, the protrusion may be formed on at least the tip of the protrusion, and the protrusion may be formed by a plurality of juxtaposed protrusions. The length of the protrusion does not necessarily have to be larger than the thickness of the filter 22, and may be any length as long as the filter 22 can be hooked. The number of the protrusions 29 does not have to be plural, and may be one, but preferably plural (for example, 3
~ 30), and more preferably about 5-20.
The protrusion may have a hook shape with a bent tip. further,
The protruding piece 28 does not necessarily have to be formed at the end of the substrate 27, and may be provided at the center of one surface of the substrate 27.

The latching member is not limited to the structure described above, and is not particularly limited as long as it has a protrusion capable of latching the filter 22. For example, a plurality of protrusions may be formed on the substrate 27 randomly or under a certain regularity.

In a preferred hooking member, at least one tip of the substrate has a projection piece having a plurality of juxtaposed projections at least at its tip end, and an abutment surface capable of abutting the string-like body is formed. . The contact surface may be formed by a plurality of juxtaposed protrusions themselves. It is preferable that the protrusion pieces are inclined in a direction orthogonal to the parallel direction of the protrusions.

Furthermore, the disposing direction of the retaining member 26 is not limited to the above, and can be appropriately selected within a range that does not impair the filter retaining function. The fixing of the locking member 26 to the side surface 30 of the frame body 29 is not limited to the adhesive tape, but a conventional fixing means such as a magnet or a suction cup can be used. Further, the part of the filter 22 that is hooked on the hooking member 26 is not limited to the above, but the filter 2
It suffices if it is a portion that can restrict the movement in the parallel direction with respect to the second filter mounting surface.
