DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for fixing a filter for covering a front surface of a suction port of a vent of an exhaust port such as a range hood or a ventilation fan to the ventilator, and a filter for an exhaust port using the fixture. Related to the mounting method.

[0002]

2. Description of the Related Art Exhaust outlets of range hoods, ventilation fans, etc.
Since inhaled dirty air and oily smoke generated in the kitchen are inhaled and exhausted to the outside, it is extremely dirty and requires a great deal of cleaning work. Therefore, the front surface of the intake port of the exhaust port is covered with a replaceable sheet filter made of a nonwoven fabric or the like,
By trapping dust and oily smoke, the exhaust port is kept clean.

[0003] However, since the exhaust port is usually installed at a high position in the room, the work of mounting the filter is complicated. In addition, even if a filter is attached, the filter is likely to shift or come off due to the suction force of the exhaust port fan.

Japanese Patent Application Laid-Open No. 4-131113 and Japanese Patent Publication No. 6-7895 disclose a method of mounting a filter in which a filter is fixed to a ventilator by pressing a peripheral portion of the filter with a magnet holder with a handle. I have. However, in this method, since the contact surface of the magnet holder with the filter is flat, the filter is easily displaced by the suction force of the fan at the exhaust port acting in the direction perpendicular to the magnetic force direction of the magnet.

Japanese Patent Application Laid-Open No. 4-131113 discloses that a non-woven fabric is used as a filter member, and an engaging means for engaging the non-woven fabric in advance, for example, a base provided with hook-shaped projections, and a large number of hook-shaped objects on the surface. A method of attaching a filter member to an exhaust port for attaching a provided planar fastener or the like around an exhaust port, covering the exhaust port with the nonwoven fabric, and temporarily fixing a peripheral portion of the nonwoven fabric to the engaging means is disclosed. I have. A similar method for fixing the filter member with a planar fastener is disclosed in
JP-A-32508, JP-A-5-7318 and JP-A-6-22836.

However, in the method using a base provided with hook-shaped projections described in Japanese Patent Application Laid-Open No. 4-131113, although the movement of the filter in the direction parallel to the filter surface is restricted by the hook-shaped projections, the exhaust port If the engagement between the filter and the hook-like projections becomes loose during the repetition of the operation and stop of the fan, the filter may move along the hook-like projections and eventually come off the tip of the hook-like projections. is there. In the method of fixing the filter member with the planar fastener, only the fibers near the surface of the filter member are engaged with the hooks of the planar fastener, so that the filter is attached to the exhaust port having a fan with a strong suction force. When the filter is attached or when the fiber density of the filter member is low, the filter may come off due to long-term use.

In Japanese Utility Model Laid-Open No. 4-32508,
A magnet piece provided with an adhesive for attaching a filter member to one surface of a magnet is disclosed. However, with this magnet piece, a filter having an uneven surface cannot be firmly fixed.

Further, in Japanese Patent Application Laid-Open Nos. 4-131113 and 4-118120, a protruding body formed of a magnet or the like is attached around an exhaust port, and a sheet-like filter member is placed over the protruding body. Thereafter, a method of mounting the filter member on an exhaust port for fixing the filter member by covering the projection with a cap in a state where the filter member is sandwiched is disclosed. However, even in this method, when the filter is sucked by the fan of the exhaust port, the cap may be pushed outward by the filter sandwiched between the cap and the protruding body, and may come off the protruding body.

[0009]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fitting for a filter for an exhaust port, which can be easily mounted, and which can securely and stably fix the filter to the exhaust port, and a method for attaching the filter to the exhaust port. An object of the present invention is to provide a method for mounting a filter.

It is another object of the present invention to provide a fitting for a filter for an exhaust port which can be easily replaced, and a method for attaching a filter to an exhaust port.

[0011]

The present inventors have conducted intensive studies to achieve the above object. As a result, the use of a fixture having a specific structure makes it extremely easy to attach the filter to the exhaust port. Instead, they found that the filter attached to the exhaust port did not shift or come off for a long period of time, and completed the present invention. In the present specification, the exhaust port means the entire exhaust device including the range hood main body and the ventilation fan main body.

That is, the first fitting for the exhaust port filter of the present invention comprises a holding means for holding a peripheral portion of a sheet-like filter which covers the front surface of the suction port of the exhaust port, and the holding means for the exhaust port. A fixing device for a filter having fixing means for fixing, wherein the clamping means extends from a portion corresponding to a bottom of a concave substrate and a bottom of a concave portion of the substrate, and a peripheral portion of the filter is provided between the substrate and the substrate. And a plate-like piece capable of forming a gap for inserting the filter and pressing the filter with the substrate, wherein the plate-like piece elastically presses the filter against the filter mounting surface. It has a bent part.

[0013] In the first attachment, the peripheral portion of the sheet-like filter covering the front surface of the suction port of the exhaust port is inserted between the substrate and the plate-like piece, and is inserted between the substrate and the plate-like piece. while挾圧, before Ki挾 simple operation of fixing the periphery of the inlet of the exhaust port (peripheral wall portion) by a fixing means lifting means, it is possible to attach the filter to the exhaust port. Also,
Since the substrate and the plate-like piece for holding the filter are integrally formed, the holding force of the filter can be increased, and separation and disassembly of the holding means during use can be suppressed. Therefore, a high clamping function can be maintained for a long time, and the filter can be fixed reliably and stably until the replacement time.
Further, since the filter can be easily removed only by releasing the holding of the filter by the holding means, the replacement work of the filter can be performed extremely easily. Further, in the first mounting tool, since the plate-like piece has a convex portion or a bent portion capable of pressing the filter to the filter mounting surface by elasticity, the filter is strongly clamped between the substrate and the plate-like piece. Can be firmly fixed to the exhaust port.

According to the second aspect of the present invention, there is provided a fitting for a filter for an exhaust port disposed between an exhaust port and a sheet-like filter that covers the front surface of an intake port of the exhaust port, and is fixed to the exhaust port. Mounting device for a filter having fixing means for the filter, comprising: a case having a space in which the filter can be inserted; and a sheet-like elastic body provided on the filter insertion portion side of the case. A non-linear cutout for locking the filter is formed.

In the second fitting, the required number of the fittings are fixed around the suction port of the exhaust port by the fixing means, and the front surface of the suction port of the exhaust port and the case of the fitting are covered with a sheet-like filter. The filter can be inserted into the space of the case from the cut portion of the sheet-like elastic body by pressing the portion of the filter covering the cut portion toward the inside of the case. At this time, the filter inserted into the space of the case has a folded portion (wrinkle),
The cut piece at the cut portion of the sheet-like elastic body is bent into the space of the case with insertion of the filter. Then, since the folded sheet-shaped filter and the cut piece formed of the elastic body have a restoring force that tends to return to the original shape, the folded portion of the filter has the restoring force of the folded portion itself and the cut. It is firmly locked by the restoring force of the piece.

Therefore, according to this mounting tool, the filter can be mounted by a simple operation of pressing the filter, and the filter is fixed by the restoring force of the folded portion of the filter and the cut piece. Even if it is sucked by the fan of the exhaust port, it is hard to come off the case. Therefore, the filter can be reliably and stably fixed to the exhaust port for a necessary period. Further, since the filter can be removed only by pulling out the inserted filter from the cut portion, it is not necessary to replace the filter.

According to a third aspect of the present invention, there is provided a fitting for a filter for an exhaust port having a fixing means for fixing the filter to the exhaust port, and at least a part of the fixture for covering a front surface of a suction port of the exhaust port. A fitting for a filter for an exhaust port, wherein a tooth-shaped engaging portion for penetrating and locking the filter is formed at a contact portion with the filter, and a magnet for fixing to the exhaust port And the toothed locking portion is formed at one end of the side of the casing. The fourth exhaust port filter fixture of the present invention has a fixing means for fixing to the exhaust port, and at least a part thereof is disposed on a sheet-like filter covering the front surface of the exhaust port intake port. A fitting for a filter for an exhaust port, in which a tooth-like engaging portion for penetrating and locking the filter at a contact portion with the filter is formed, wherein the fixing means for fixing to the exhaust port is And a flange on the side of the casing, and at least the tooth-shaped locking portion is formed on the flange.

In the third and fourth attachments, the portion where the tooth-shaped locking portion is formed is placed on a sheet-like filter that covers the front surface of the suction port of the exhaust port. The filter is locked to the locking portion only by lightly pressing the locking portion toward the filter, so that the filter can be easily attached to the exhaust port. In this attachment, since the tips of the teeth of the locking portions come into contact with the surface of the exhaust port, even when the entire attachment is placed on the filter, the displacement of the filter due to the suction force of the fan can be prevented. In addition, since the root of the “teeth” of the locking portion is located outside (front side) of the filter, the filter does not fall off from the tip of the tooth-shaped locking portion. Therefore, the filter can be reliably and stably fixed to the exhaust port for a long time.

In the method of mounting a filter on the exhaust port according to the present invention, the front surface of the intake port of the exhaust port is covered with a sheet-like filter, and the filter is fixed by any one of the first to fourth mounting tools.

In this mounting method, the first to fourth mounting tools are used.
The filter can be easily removed, and the filter can be fixed securely and stably for a long period of time.

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

FIG. 1 is a perspective view showing one embodiment of a first mounting device of the present invention, and FIG. 2 is a schematic perspective view showing one embodiment of a filter mounting method of the present invention using the mounting device of FIG. It is.

The fixture 4 is a substantially concave substrate 5 having a U-shaped notch formed substantially at the center of one long side of a rectangle.
A holding member consisting of a plate-like piece 6 extending obliquely upward from a portion corresponding to the bottom of the cutout portion of the substrate 5; and an adhesive tape 7 attached to one surface of the substrate 5 and having an adhesive layer on the surface. It is composed of

In order to increase the holding force of the holding member and firmly and surely hold the filter, the plate-like piece 6 extends from the center of the substrate 5 from the rear as viewed from the direction in which the plate-like piece 6 extends. The length of the plate-like piece 6 is longer than the length of the substrate 5 in the vertical direction (the direction in which the plate-like piece 6 extends).

The holding member is integrally formed of an elastic material. Such materials include, for example, metal materials such as steel and plastics. In this example, a bent portion 8 having a V-shaped cross section having a top portion below (on the side in contact with the filter 1) is formed in the middle of a plate-like piece 6 extending from the substrate 5.

The filter 4 can be attached to the exhaust port by the attachment 4 as follows. That is, the front surface of the suction port 3 of the range hood 2 which is an example of the exhaust port is covered with the sheet-shaped filter 1, and the fitting 4 is provided at an appropriate position around the suction port of the range hood 2 corresponding to the periphery of the filter 1. Is fixed with an adhesive tape 7. The suction port 3 is provided with a mesh such as a wire net in order to prevent the filter from being sucked. Then, the end of the plate-like piece 6 of the fixture 4 is pulled outward, and the substrate 5 and the plate-like piece 6
After the peripheral edge of the filter 1 is inserted into the gap having a V-shaped cross section formed between the filter and the plate-shaped piece 6, the plate-shaped piece 6 is removed.
The plate-shaped piece 6 moves inward due to the elastic force of the above, and the gap is closed. Therefore, the filter 1 is pressed by the plate-shaped piece 6 and is strongly clamped between the substrate 5 and the plate-shaped piece 6. Also,
Since the filter 1 is pressed toward the range hood 2 by the top (convex portion) of the bent portion 8, the filter 1 can be firmly fixed. In FIG. 2, illustration of the bent portion 8 of the attachment 4 is omitted.

As described above, in this example, the filter 1 is provided between the substrate 5 and the plate-like piece 6 by utilizing the elastic force of the plate-like piece 6.
The filter 1 can be mounted by a simple operation of sandwiching the filter 1.
In addition, since the fixture 4 is directly fixed to the range hood 2 by the adhesive tape 7 and the filter 1 is clamped by the integrally formed clamping member composed of the substrate 5 and the plate-shaped piece 6, the filter 1 is held. It can be securely and firmly fixed to the range hood 2 for a long period of time. Further, when replacing the filter 1, the filter 1 can be easily removed simply by pulling the plate-like piece 6 outward.

In this example, the shape of the plate-like piece 6
The extending position of the plate-like piece 6 on the substrate 5 and the length of the plate-like piece 6 are not limited to the above, and the filter 1
Any shape can be used as long as it can hold the sheet. The width of the plate-shaped piece 6 is appropriately determined within a range in which the holding function by the plate-shaped piece 6 is not impaired. The substrate 5 and the plate-like piece 6 do not need to be integrally formed products, and members prepared separately in advance may be joined by welding, fusion, or the like. The shape of the bent portion 8 of the plate-shaped piece 6 is not limited to the above, and may be any shape as long as the filter 1 can be pressed toward the range hood 2.

The substrate 5 and the plate-like piece 6 may be made of any of hard and soft materials. On the surface of the substrate 5 and the plate-like piece 6 on the side where the filter is sandwiched, irregularities for increasing the frictional force may be formed, or projections for locking the filter may be formed.

As a means for fixing the substrate 5 to the exhaust port, in addition to the adhesive tape 7 such as a double-sided tape, a conventional fixing means such as an adhesive, an adhesive, a magnet, a suction cup, and a screw may be used. it can.

FIG. 3 is a perspective view showing an embodiment of the second fixture of the present invention, and FIG. 4 is a cross-sectional view showing a use state of the fixture of FIG.

The attachment 31 is a case 3 having a sheet-like lid 34 in which a cut portion 35 for retaining a filter is formed and an edge 33 for fixing the lid 34.
2 and an adhesive tape 7 attached to the back side of the bottom surface of the case 32 and having an adhesive layer on the surface. The lid 34 is made of a material having elasticity and flexibility,
For example, it is formed of a resin such as rubber or polyvinyl chloride.

The fixture 31 shown in this example can be used as follows. That is, the attachment 31 is fixed to the periphery of the inlet of the range hood 2 at an appropriate interval by the adhesive tape 7, and the front surface of the inlet of the range hood 2 and the case 32 are covered with the sheet-like filter 2. cover. And
The part of the filter 1 that covers the lid 34 of the case 32 is
The filter 1 is inserted into the case 32 from a cut portion 35 formed in the lid 34 by pressing the filter 1 toward the space inside the case 32 with a finger or the like. At this time, the filter inserted into the case is formed with a fold portion, and the cut piece forming the cut portion 35 is bent or curved into the case as the filter is inserted. for that reason,
The folds of the inserted filter 1 are formed by the restoring force of the folds of the filter itself and the cuts 3 formed by an elastic body.
By virtue of the action of the notch piece 5 and the restoring force, it is strongly clamped by the notch piece.

As described above, in this example, the filter 1 can be attached by a simple operation of pressing the filter 1 and the filter 1
The folds formed when inserted into the hood 2 are locked in a state of being sandwiched (or pinched) by a plurality of cut pieces having a restoring force. Even if sucked by the fan, it does not come off from inside the casing 32. Therefore, the filter 1 can be reliably and stably fixed to the range hood 2 for a necessary period. Further, the filter 1 can be removed simply by pulling out the inserted filter 1 from the inside of the casing 32, so that the filter 1 can be easily replaced. Further, in this example, the lid 34
Is formed of an elastic body, the operation of inserting and removing the filter 1 into and from the casing 32 can be performed smoothly, and the filter 1 can be prevented from being damaged.

It is not necessary that the entire cover 34 has elasticity and flexibility, and it is sufficient that at least the cut portion 35 has such characteristics, particularly elasticity. The case 32 and the edge 33 can be formed of, for example, metal such as iron or plastic.

The cut portion 35 formed in the cover 34 is non-linear so that the filter 1 can be inserted smoothly and securely fixed, for example, in a curved shape, a saw-tooth shape, a broken line shape and / or a radial shape. It is preferably formed. A more preferable shape of the cut portion 35 is a saw-tooth shape and / or a radial shape at a central portion, and a straight shape at an end portion.

The number of the cut portions 35 may be one or plural. The means for fixing the case 32 to the range hood 2 is not limited to the adhesive tape 7, and the above-described conventional fixing means can be used.

In addition, in the mounting device, the lid 34 and the rim 33 are not always necessary, and the cut portion 35 may be formed on the filter insertion portion side of the case 32.

FIG. 5 is a perspective view showing an embodiment of the third fixture of the present invention, and FIG. 6 is a sectional view showing a use state of the fixture of FIG.

The attachment 37 in this example is the range hood 2
And a casing 38 that accommodates the magnet 53 and has a tongue-shaped flange 39 formed on the side. The casing 38 has a cylindrical shape having a bottom on one side only, and the flange 39 extends laterally from an end of the casing 38 on which the bottom is not formed. The end of the casing 38 where the bottom is not formed is
A tooth-shaped locking portion 40 for locking the filter 1 is formed over substantially the entire circumferential direction. The height of the teeth of the locking portion 40 is formed larger than the thickness of the filter 1. The flange 39 is formed integrally with the casing 38.

In the mounting member 37, since the magnet 53 is housed in the casing 38, the range hood 2 made of a material that is attracted to the magnet such as iron is a sheet-shaped cover that covers the front surface of the suction port. The filter 1 can be attached to the range hood 2 by simply placing the filter 1 on the side where the tooth-shaped locking portion 40 is formed in contact with the filter 1 and pressing it lightly. Further, since the flange portion 39 is formed on the side portion of the casing 38, the mounting operation is easy.

In this example, the height of the tooth is
The filter 1 is locked by the tooth-shaped locking portion 40 and the tip of the tooth of the locking portion 40 is formed on the surface of the range hood 2. Therefore, as shown in FIG. 6, even when the entire mounting fixture is placed on the filter 1, displacement of the filter 1 due to the suction force of the fan is prevented. Furthermore, since the roots of the teeth of the locking portion 40 are located outside (front side) of the filter,
The filter 1 does not fall off from the tip of the toothed locking portion 40.

Further, since the flange 39 is formed at the end of the casing on the side in contact with the filter 1, the extending position of the flange 39 is adjusted to the tooth of the tooth-shaped locking portion 40. By adjusting in consideration of the height or the like, the flange 39 can function as a filter holder. for that reason,
The displacement of the filter 1 in the direction perpendicular to the magnetic force direction of the magnet 53 can be further suppressed, and the filter 1 can be fixed to the range hood 2 reliably and stably for a long time. In addition, collar 3
Since 9 is an integrally molded product with the casing 38, it can be easily manufactured.

The casing 38 is provided with the tooth-shaped locking portion 4.
It may have two bottoms as long as the locking of filter 1 by zero is not impaired. Furthermore, the shape of the casing 38 is not limited to a cylindrical shape, and may be any shape such as a rectangular parallelepiped as long as the shape can accommodate the magnet 53 and form the tooth-shaped locking portion 40.

The number and shape of the teeth of the toothed locking portion 40 can be appropriately selected within a range that does not impair the locking ability of the filter 1. The toothed locking portion 40 is not always
May not be formed over the entire circumferential direction of the end portion, and may be formed on a part of the circumferential direction. Further, the shape of the flange 39 is not particularly limited, but may be a circle, an ellipse, a semicircle, a sector, or the like to increase the area in order to enhance the function as a filter holder. in this case,
The number of attachment points of the attachment 37 can be reduced, and the replacement operation can be further simplified. Further, the flange portion 39 and the casing 38 do not necessarily have to be integrally formed, but may be formed separately and then integrated by bonding, fusion or the like. Furthermore, the flange 39 does not necessarily have to be formed.

FIG. 7 is a perspective view showing another example of the third fixture of the present invention. This example is different from the attachment of FIG. 5 in that a tooth-like locking portion for locking the filter is formed not only at the end of the casing but also at the flange. That is, in the mounting tool 41 of this example, the tooth-shaped locking portion 45 is formed over substantially the entire circumferential direction of the end of the casing 42 accommodating the magnet, and the side of the casing 42 extends from the side. To the end of the flange 43 extending in the direction
6 is provided. The direction of the teeth of the toothed locking portion 46 is the same as the direction of the locking portion 45, and the position of the tip of the locking portion 46 is substantially flush with the position of the tip of the locking portion 45. Is formed.

In this example, the filter 1 can be further firmly fixed because the tooth-shaped locking portion is formed not only at the end of the casing 42 but also at the flange 43.

FIG. 8 is a perspective view showing an embodiment of the fourth fixture of the present invention, and FIG. 9 is a sectional view showing a use state of the fixture of FIG.

The attachment 47 has a point in which a tooth-shaped locking portion is not formed at an end of a casing accommodating a magnet, and a point in which a flange portion extending laterally from a side of the casing is semicircular. 7 is different from the attachment 41 of FIG. That is,
In this example, the casing 48 accommodating the magnet 53 is not provided with the tooth-shaped locking portion, and the tooth-shaped locking portion is formed from the end of the semicircular flange 49 extending laterally from the side of the casing 48. A locking piece 50 having a locking portion 51 extends downward in a direction substantially perpendicular to the flange 49. The tips of the teeth of the locking portion 51 are located substantially in the same plane as the surface formed by one end of the side portion of the casing 48.

In this attachment 47, the filter 1 is ranged by arranging the portion of the casing 48 accommodating the magnet 53 outside the peripheral edge of the filter 1 and arranging at least a part of the flange 49 on the filter 1. It can be attached to the hood 2. In this example, the portion of the casing 48 accommodating the magnet 53 can be directly fixed to the range hood 2 without the intervention of the filter 1, so that the mounting stability is improved,
Even if the suction force of the fan of the range hood 2 acts, it is difficult to shift. Further, since the filter 1 can be locked by the locking pieces 50 having the tooth-shaped locking portions 51, the filter 1 can be fixed securely.

In this example, the shape of the flange portion 49 can be appropriately selected within a range that does not impair the locking property with respect to the filter 1, and is not limited to a semicircular shape, and may be, for example, a fan shape.

In a preferred embodiment of the third and fourth attachments, the casing has a casing for accommodating a magnet to be fixed to the exhaust port, a flange is provided on a side of the casing, and at least the filter is provided on the flange. Are formed in order to lock the teeth.

The first to fourth attachments of the present invention can be widely used for attaching and fixing a filter to an exhaust port such as a ventilation hood as well as the range hood. In addition, since the filter of the present invention can securely fix the filter to the exhaust port, it is particularly useful when the filter is directly covered and fixed to the front surface of the exhaust port, but the filter is mounted via a frame or a support. It can also be used when

[0054]
