Description

  The present invention relates to a filter device disposed within and to a filter plate provided with the same.

  In general, rainwater that has fallen on a roof or the like is collected by rainwater in a residential area and penetrated into the ground by rainwater penetration. In addition, miscellaneous wastewater discharged from houses and the like is collected in the drainage in the residential land through a drain pipe. After that, rainwater that could not penetrate into the ground flows into the gutter or sewer main installed on the public road, and miscellaneous wastewater flows into the sewer main.

The rainwater and miscellaneous drainage that pass through these rainwater drainage pipes and drainage pipes may be mixed with garbage such as dead leaves and food. Therefore, for example, there is a possibility that garbage collects in the rainwater and drainage on the downstream side, and the dust accumulates and clogs in these mushrooms. Further, when a rainwater storage and penetration tank for storing and penetrating rainwater is provided in the residential land, there is a possibility that garbage accumulates in the rainwater storage and penetration tank and becomes clogged. Therefore, a filter for capturing dust so that dust does not flow into the downstream pipe has been used in the past (see, for example, Patent Documents 1 and 2 below).
Japanese Utility Model Publication No. 61-41813 JP-A-8-284245

  However, the filters disclosed in Patent Document 1 and Patent Document 2 are formed in a bowl shape, and the effective surface area of the filter is small, which causes clogging immediately. Therefore, when the filters disclosed in Patent Document 1 and Patent Document 2 are used, it is necessary to frequently perform maintenance such as inspection and cleaning for clogging.

  The present invention has been made in view of the above points, and an object of the present invention is to reduce clogging and reduce the frequency of maintenance with respect to a filter device disposed inside and a filter equipped with the filter device. There is to do.

  The filter device according to the present invention is arranged in a basin having an inflow port to which an inflow pipe for inflowing wastewater consisting of rainwater or miscellaneous drainage is connected, and an outflow port to which the outflow pipe for outflowing the wastewater is connected. It is a filter device, and is formed by a filter member that allows the waste water to pass therethrough, and at least partly partitions between the inflow port and the outflow port, and at least partly stands upright in the cylinder. The filter main body part and a bottom part closing the lower end of the filter main body part are provided, and the upper end of the filter main body part is located above the upper end of the outlet.

  Here, the “filter member” includes, for example, a net-like body such as a metal mesh or a resin mesh, a porous body, a perforated plate such as a punching metal, or the like. “Closing the lower end of the filter body” includes both the case where the lower end of the filter body is closed in a watertight state and the case where the drainage is allowed to pass through.

  According to the filter device, for example, even when wastewater mixed with dust (that is, rainwater or miscellaneous wastewater) flows into the inlet from the inlet, the dust is captured by the filter body, Outflow from the outlet is prevented. According to the filter device, at least a part of the filter main body is formed in a substantially cylindrical shape. For this reason, the surface area of the filter main body can be ensured larger than that of the conventional technique (saddle-type filter), although it is arranged in the interior of a limited installation space. Moreover, since at least a part of the filter main body is formed in a substantially cylindrical shape, the drainage can be passed from almost the entire periphery. Therefore, even if clogging occurs in a part of the filter body, dust can be removed from other parts of the filter body without particularly hindering the flow of drainage flowing inside and outside. Therefore, it is possible to reduce the frequency of maintenance that has been frequently performed in the past.

  Furthermore, according to the said filter apparatus, the upper end of the filter main-body part is arrange | positioned above the upper end of an outflow port. Therefore, even if clogging occurs in a part of the filter body due to long-term use, the clogged part only moves from the lower side of the filter body to the upper side, A portion where no clogging occurs can be secured. As described above, according to the filter device, since at least a part of the filter main body is formed in a substantially cylindrical shape, the filter device is erected inside, so that clogging can occur even after a long period of use. A portion that does not occur can be secured. Therefore, it is possible to further reduce the frequency of maintenance that has been frequently performed in the past.

  It is preferable that the upper end of the filter body is open.

  It is considered that the filter main body portion of the filter device is clogged from the lower side due to trapped dust. The clogging gradually reaches the upper side as time elapses, and if the maintenance is not properly performed, it is considered that the filter main body portion is finally covered. For this reason, if clogging progresses faster than expected or if maintenance is forgotten, the entire filter may become clogged. If the upper end of the filter is blocked, drainage will occur when water increases. There is a risk of overflowing.

  However, if the upper end of the filter body is open, even if the entire filter body is clogged, the drainage should be bypassed from the opening at the upper end of the filter body to the inside of the filter body. The waste water can be discharged from the outlet to the outside. Therefore, according to the filter device, even if the entire filter main body is clogged, the drainage can be prevented from overflowing from the inside.

  The filter device further includes a lid portion that closes an opening at an upper end of the filter main body portion, and the filter main body portion has an opening portion or a circulation portion having a coarser opening than other portions on the upper side of the outlet. You may have.

  Here, the “lid portion that closes the opening at the upper end of the filter main body” may not be able to pass drainage or may be allowed to pass.

  According to the above filter device, since the lid portion that closes the opening at the upper end of the filter main body portion is provided, when dust such as dead leaves falls from above during installation or maintenance, the dust is removed. Intrusion into the filter main body can be prevented. Moreover, according to the said filter apparatus, even if it is a case where substantially the whole filter main-body part is clogged, waste_water | drain can be guide | induced to the further outflow port from the opening part or distribution | circulation part of a filter main-body part. Therefore, according to the filter device, it is possible to prevent the drainage from overflowing from the inside even when the filter body is substantially clogged.

  It is preferable that a part of the side part of the filter main body part covers the outlet of the basin and forms an outflow part through which drainage passes from the inside to the outside of the filter main body part.

  According to the above filter device, the waste water that has flowed into the inlet from the inlet first passes through the portion other than the outlet of the filter body, enters the inside from the outside of the filter body, and then passes through the outlet. Moves from the inside of the filter body to the outside and flows out from the outlet. As a result, the drainage passes through the filter body part twice. Therefore, according to the said filter apparatus, an outflow port will be covered doubly and dust collection capability can be improved.

  The filter device may further include a support member that detachably supports the filter main body portion in the first wall so that the outlet port is covered with a part of the filter main body portion.

  According to the filter device, since the filter main body is detachable from the support member, inspection work and maintenance work can be easily performed.

  The lower end of the filter main body is opened, and the filter device has a bottom made of a filter member as the bottom, and closes the lower end of the filter main body with the bottom and detachably supports the filter main body. It may further include a supporting member.

  According to the filter device, since the filter main body is detachable from the support member, inspection work and maintenance work can be easily performed. Moreover, since the bottom part of the support member is formed by the filter member, the waste in the wastewater flows into the inside of the filter body part from the lower end of the filter body part, even though the lower end of the filter body part is opened. It is prevented. Moreover, according to the said filter apparatus, the shape of a filter main-body part can be simplified and a filter main-body part can be formed comparatively easily. In addition, when dust enters the inside of the filter body, the dust accumulated on the bottom of the support member can be easily taken out by removing the filter body from the support member. Thereby, maintenance work can be facilitated.

  An insertion part that can be inserted into the outlet is formed on a side part of the filter body part, and the filter body part is attached to the gusset by inserting the insertion part into the outlet. There may be.

  According to the filter device, the filter main body can be attached to the outlet without the support member, so that the number of parts can be reduced. Further, the filter main body can be attached and detached by a simple operation of inserting the insertion portion into the outlet. Thereby, inspection work and maintenance work can be facilitated.

  The filter main body and the bottom are elbow-shaped substantially cylindrical bodies made of integrally formed filter members, and are attached to the skirt by inserting a part of the substantially cylindrical body into the outlet. It may be.

  Also in the filter device, since the filter main body can be attached to the outlet without a support member, the number of parts can be reduced. Further, the filter main body can be attached and detached by a simple operation of inserting the insertion portion into the outlet. Thereby, inspection work and maintenance work can be facilitated.

  The bottom is preferably located below the lower end of the outlet.

  As a result, even if dust with a large specific gravity has entered the inside of the filter main body, the dust accumulates below the outlet, so that the flow of drainage through the outlet is obstructed. Can be suppressed.

  The filter according to the present invention has an inflow port to which an inflow pipe for inflowing rainwater or miscellaneous wastewater is connected and an outflow port to which an outflow pipe for outflowing the drainage is connected. When the filter is formed into a shape, the filter device is provided.

  According to the above filter, since the filter device is provided, it is possible to capture dust mixed in rainwater or miscellaneous wastewater. In addition, the maintenance frequency can be reduced as compared with the conventional one.

  It is preferable that the filter bowl is made of a cylindrical body with a bottom, has a handle, and further includes a container that is inserted into and removed from above, and the filter device is attached to the container.

  According to the filter, since the filter device is attached to the container, the filter device can be easily attached to the inside by inserting the container into the container from above. The container is provided with a handle. Therefore, the container can be easily taken out. Thereby, the maintenance work can be facilitated. Further, the dust removed by the filter device and accumulated in the container can be easily taken out together with the container.

  In addition, another filter according to the present invention is formed with an inflow port to which an inflow pipe for inflowing rainwater or miscellaneous wastewater is connected and an outflow port to which an outflow pipe for outflowing the drainage is connected, A filter having a bottomed cylindrical body and a filter device having the support member, and comprising a bottomed cylindrical body, having a handle, and having a handle from above. A container to be inserted and removed is further provided, and the support member is formed integrally with the container.

  Since the above-mentioned filter is also equipped with a filter device, it is possible to capture dust mixed in rainwater or miscellaneous wastewater. In addition, the maintenance frequency can be reduced as compared with the conventional one. Furthermore, since the support member and the container are integrated, a process of attaching the support member to the container is not required when installing the filter device, and installation work and maintenance work are facilitated.

  As described above, according to the present invention, the frequency of maintenance can be reduced with respect to the filter device disposed inside and the filter equipped with the filter device.

  FIG. 7A is a plan view of the filter 21, and FIG. 7B is a view in which the left half of the filter 21 is represented as a side surface and the right half is represented as an end surface (that is, only the end surface in the cross section of the filter 21 is displayed. The other part is a diagram showing only the outline). In this embodiment, as shown to Fig.7 (a), (b), the filter 21 is comprised by the cylinder part 21a formed of the substantially cylindrical net-like body. The upper end and the lower end of the cylindrical portion 21a of the filter 21 are open. In this embodiment, the filter 21 is formed so as to have an inner diameter (φ100) that is substantially equal to the inner diameter of the outflow pipe 12 (see FIGS. 2 and 3). In the present embodiment, the filter 21 is made of metal. However, it is also possible to form the filter 21 with other materials, such as resin.

  In addition, the cylindrical filter 21 which concerns on this invention is not restricted to a cylindrical thing like this embodiment. For example, a cylindrical body having a polygonal cross section may be used, and a cylindrical body having an oval cross section may be used.

  FIG. 8A is a plan view of the support member 22, and FIG. 8B is a longitudinal sectional view of the support member 22. As shown in FIGS. 8A and 8B, the support member 22 is formed on the body 22a and the bottom 22b for supporting the tubular filter 21 (see FIG. 3), and on the side surface of the body 22a. And an attaching / detaching portion 22c.

  As shown in FIG. 8B, the body 22 a is formed in a shape in which a part of a cylinder having an inner diameter larger than the outer diameter of the cylindrical filter 21 is cut out.

  As shown in FIGS. 8A and 8B, the bottom 22b has a plurality of holes h and is formed in a lattice shape. An annular protrusion p protruding upward is formed on the bottom 22b. The protrusion p is formed so that the outer diameter is smaller than the inner diameter of the body portion 22 a and smaller than the inner diameter of the cylindrical filter 21. With such a configuration, the cylindrical filter 21 is mounted on and supported by the support member 22 by being placed inside the trunk portion 22a and above the bottom portion 22b and outside the protrusion p. It becomes.

  The detachable portion 22c is formed in a substantially cylindrical shape and protrudes laterally from the side surface of the body portion 22a. Further, a protruding flange of the detachable portion 22c is formed with a flange 22d that is curved in a plan view and has a rectangular shape in a side view (see FIG. 9).

The opening 22e is formed so that its diameter becomes substantially equal to the diameter of the outlet 2b of the main body 2. Further, a packing groove 22f concentric with the opening 22e is formed on the outer periphery of the opening 22e of the flange 22d. However, the packing groove 22f is not always necessary and may be omitted. Further, a pair of upper and lower convex slide rails 22g and 22g extending in the vertical direction are formed on both side surfaces of the flange 22d. The convex slide rails 22g and 22g are formed to be engageable with concave slide rails 6e and 6e formed on the inner surface of the support portion 6a of the handle 6. The support member 22 is fixed to the bucket 3 by the engagement between the convex slide rails 22g and 22g and the concave slide rails 6e and 6e.

-Installation procedure of the filter device 10-
The above is the configuration of the filter 1. Next, a procedure for mounting the filter device 10 on the filter rod 1 will be described.

  First, the filter 21 is inserted inside the trunk portion 22 a of the support member 22 and attached to the support member 22. At this time, the filter 21 is placed above the bottom 22b of the support member 22 and outside the protrusion p. Accordingly, the lower end portion of the filter 21 is supported by being sandwiched between the body portion 22a and the protrusion p on the bottom portion 22b.

  Next, the support member 22 to which the filter 21 is attached is attached to the bucket 3. Specifically, the convex slide rails 22g and 22g of the flange 22d of the support member 22 and the concave slide rails 6e and 6e of the portal handle 6 of the bucket 3 are engaged. First, the flange 22d of the support member 22 is moved to the inside of the portal handle 6 so that the convex slide rails 22g and 22g are placed between the gap above the concave slide rails 6e and 6e and between the upper part and the lower part. Arrange like Next, by sliding the flange 22d downward, the convex slide rails 22g and 22g of the flange 22d and the concave slide rails 6e and 6e of the portal handle 6 of the bucket 3 are engaged. In this way, the support member 22 is fixed to the bucket 3.

  After attaching the support member 22 to which the filter 21 is attached to the bucket 3, the bucket 3 is attached to the filter 1. Specifically, the bucket 3 is lowered from the inspection cylinder 4 of the filter 1 toward the main body 2 gradually. At this time, the bucket 3 is lowered so that a vertical groove (not shown) formed on the outer surface of the support portion 6a and a pair of slide protrusions 2e, 2e formed on the main body 2 are engaged. In this way, the bucket 3 is fixed in the main body 2 more and more. Note that the flange 22d of the support member 22 is formed in a curved shape in plan view (see FIG. 8A), and when the bucket 3 is further fixed in the main body 2, it gradually abuts against the inner wall surface of the main body 2. .

  As described above, the filter device 10 is mounted in the filter 1 as shown in FIG. At this time, the upper end of the cylindrical filter 21 is disposed above the upper end of the outlet 2b. The bottom 22b of the support member 22 has a lower end disposed below the lower end of the outlet 2b. In the present embodiment, the handle 6 attached to the bucket 3 corresponds to an attachment member for attaching the cylindrical filter 21 supported by the support member 22 to the outlet 2b.

-Operation of the filter device 10-
Next, the operation of the filter device 10 in the filter 1 will be described.

"Normal time"
First, the operation of the filter device 10 at the normal time will be described with reference to FIG.

  As shown in FIG. 10A, rainwater that has flowed into the filter 1 from the inflow pipe 11 is temporarily stored in the main body 2. In the present embodiment, since the filter bowl 1 includes the bucket 3, rainwater is stored in the bucket 3. Rainwater stored in the bucket 3 passes through the filter 21 and enters the cylindrical filter 21. When the rainwater level in the bucket 3 exceeds a predetermined water level (the position of the bottom of the outflow pipe 12), the rainwater flows out to the outflow pipe 12.

  By the way, the rainwater flowing in from the inflow pipe 11 may be mixed with dust such as dead leaves. However, the present filter 1 includes a filter device 10. Therefore, when rainwater enters the inside of the filter 21, dust such as dead leaves mixed in the rainwater is filtered by the filter 21 made of a net and does not enter the filter 21. As a result, only rainwater enters the filter 21, and dust is removed outside the filter 21. The rainwater that has entered the filter 21 passes through an outflow portion 21e that is a part of the filter 21 and covers the outflow port 2b, and is discharged from the outflow port 2b. In this way, the present filter 1 can capture dust in rainwater and prevent the dust from flowing downstream.

<When clogged>
Next, the operation of the filter device 10 when the filter 21 is clogged due to long-term use will be described with reference to FIG.

  When the filter device 10 is used for a long period of time without being replaced, the filter 21 is gradually clogged with trapped dust. When the filter 21 is clogged, rainwater cannot enter the clogged portion. The filter 21 is gradually clogged from the lower part of the cylindrical portion 21a that is most frequently in contact with rainwater.

  By the way, the filter 21 of the present filter device 10 is formed in a cylindrical shape and extends long upward, and its upper end is disposed above the upper end of the outlet 2b. Therefore, even if the lower part of the filter 21 is clogged, rainwater can enter the inside of the filter 21 from the part not clogged above the clogged part of the filter 21. In this way, even when the lower portion of the filter 21 is clogged, rainwater can be allowed to flow in from the upper clogged portion without replacing the filter 21.

  However, if the filter 21 continues to be used without being replaced, the clogging will eventually spread over substantially the entire filter 21 (excluding the outflow portion 21e). However, when substantially the entire filter 21 (except the outflow portion 21e) is clogged, rainwater cannot be allowed to flow into the filter 21. Rainwater that cannot flow into the filter 21 is accumulated in the bucket 3 without flowing out from the outflow pipe 12.

  However, the upper end of the filter 21 of the filter device 10 is open. Therefore, even if almost the entire filter 21 is clogged, it can overflow into the filter 21 from the opening at the upper end of the filter 21 when the rainwater level WL reaches the upper end of the filter 21. In other words, rainwater can be bypassed to the inside of the filter 21 from the opening at the upper end of the filter 21. And the rainwater bypassed in the filter 21 passes through the outflow part 21e which is a part of the filter 21, and covers the outflow port 2b, and is discharged | emitted from the outflow port 2b. In this way, according to the present filter device 10, even if the filter 21 is clogged and cannot pass rainwater, the rainwater is bypassed into the filter 21 from the upper part of the filter 21. Can drain rainwater.

-Action and effect-
As described above, according to the filter device 10 according to the first embodiment, the cylindrical filter 21 formed by the mesh body and the support member 22 having the bottom portion 22b that closes the lower end of the cylindrical filter 21 are provided. I have. Therefore, for example, even when dust flows into the filter 1 from the inflow port 2a, the dust can be captured by the cylindrical filter 21, and the dust can be prevented from flowing out from the outflow port 2b. Since the filter 21 is formed in a cylindrical shape, a sufficient surface area can be secured even though the filter 21 is installed in the main body 2 with a limited installation space.

  Further, the upper end of the filter 21 of the filter device 10 is disposed above the upper end of the outlet 2b. Therefore, in the present filter device 10, the surface area of the filter 21 can be greatly increased. Thereby, for example, even when the rainwater level rises because the lower portion of the tube portion 21a of the filter 21 is clogged and does not allow rainwater to pass, the upper portion captures dust and allows the rainwater to flow toward the outlet 2b. It becomes possible. As a result, the maximum amount of dust can be greatly increased. Therefore, according to the present filter device 10, it is possible to reduce the frequency of maintenance of the filter 21 that has been frequently performed in the past.

  By the way, it is considered that the filter 21 of the present filter device 10 is clogged from the lower side due to trapped dust. It is considered that the clogging gradually reaches the upper side as time passes, and finally covers almost the entire filter 21 (excluding the outflow portion 21e). Then, when almost the entire filter 21 is clogged, if the upper end of the filter 21 is blocked, the outflow port 2b is blocked, and rainwater cannot flow to the outflow port 2b side. Therefore, in such a case, particularly when the water volume increases, rainwater may overflow from the inside of the filter 1.

  However, the upper end of the cylindrical filter 21 of the filter device 10 is open. Therefore, even if almost the entire filter 21 is clogged, rainwater can be guided into the filter 21 from the opening at the upper end of the tubular filter 21 and can be discharged from the outlet 2b. Therefore, according to the present filter device 10, even when clogging occurs in almost the entire filter 21, it is possible to prevent the rainwater from overflowing from the inside of the filter 1 because rainwater cannot be discharged from the outlet 2 b. it can.

  Moreover, the filter 21 of the filter device 10 has an outflow portion 21e that covers the outflow port 2b. Therefore, the rainwater flowing into the filter 1 from the inlet 2a first passes through the part other than the outflow part 21e of the cylindrical filter 21 and enters the inside of the filter 21, and then passes through the outflow part 21e to the outlet. It flows out to 2b. Thereby, the rainwater that has flowed into the filter 1 from the inlet 2a passes through the filter 21 twice before being discharged from the outlet 2b. Therefore, according to the present filter device 10, the outflow port 2b is covered twice, and the dust capturing ability can be improved.

  Further, in the present filter device 10, the filter 21 is detachably formed on the support member 22, and the support member 22 is detachably formed on the handle 6 as an attachment member. Therefore, according to this filter device 10, inspection work and maintenance work can be easily performed.

  In the filter device 10, the bottom portion 22 b of the support member 22 has a plurality of holes h. As a result, the bottom 22b which is a part of the support member 22 can have a filter function. Thereby, a filter area can be expanded more. Further, by forming the support member 22 in this manner, the shape of the filter 21 can be simplified because the bottom portion does not have to be formed by the filter 21. Therefore, the filter 21 can be easily formed. In addition, when dust enters the filter 21, the dust accumulated on the bottom 22b can be easily taken out by removing the filter 21 from the support member 22. Thereby, maintenance work can also be facilitated.

  Moreover, in this filter apparatus 10, the bottom part 22b of the supporting member 22 is arrange | positioned below the lower end of the outflow port 2b. As a result, even if dust enters the filter 21, the bottom 22b is disposed below the lower end of the outlet 2b, so that the flow of rainwater is obstructed by the dust inside. Can be suppressed.

  Moreover, in this embodiment, the cylindrical filter 21 is formed in the internal diameter substantially equal to the internal diameter of the outflow pipe 12 connected to the outflow port 2b. As a result, rainwater flowing into the cylindrical filter 21 can be smoothly guided to the outflow pipe 12. For this reason, rainwater can be smoothly discharged to the outflow pipe 12 even when the amount of water increases. Therefore, since the rainwater is not smoothly discharged from the outlet 2b, the overflow of the filter 1 can be suppressed.

  The filter 1 includes a filter device 10. For this reason, it is possible to capture dust mixed in rainwater. Further, since the filter device 10 includes the cylindrical filter 21 having a large surface area, the frequency of maintenance can be reduced as compared with the conventional one.

  Moreover, in this embodiment, the filter bowl 1 has the handle 6 and is provided with the bucket 3 which consists of a bottomed cylindrical body installed in the main body 2 first. The filter device 10 is attached to the bucket 3. Therefore, according to the present filter 1, the filter device 10 can be easily mounted in the filter 1 by attaching the bucket 3. The bucket 3 is provided with a handle 6. Therefore, the bucket 3 can be easily taken out. Thereby, the dust in the rainwater captured by the filter 21 accumulates in the bucket 3, but the dust in the bucket 3 can be easily removed.

  Further, since the filter device 10 is attached to the bucket 3, the filter device 10 can be taken out when the bucket 3 is taken out. Thereby, when removing the dust in the bucket 3, the filter device 10 can be replaced, cleaned, or the like. Therefore, according to the present filter 1, maintenance work can be facilitated.

Needless to say, there is something in common.

-Action and effect-
As described above, even with the filter device 10A according to the second embodiment, for example, when dust flows into the filter 1A from the inflow port 2a, the dust is captured by the bottomed cylindrical filter 21A. Can be prevented from flowing out from the outlet 2b. Also in the present filter device 10A, since the surface area of the filter 21A can be significantly increased, the maximum amount of dust trapped can be greatly increased. Therefore, the frequency of maintenance of the filter 21A, which has been frequently performed in the past, can also be reduced by the filter device 10A.

  Also, the filter device 10A according to the second embodiment and the filter trough 1A including the same can achieve the same effects as the filter device 10 according to the first embodiment and the filter trough 1A including the same.

  In the present embodiment, the filter 21A is externally fitted to the filter 21A, and the filter 21A is hooked on the upper end of the body portion 22Aa, so that the filter 21A is attached to the support member 22A. It was supposed to be installed and supported. However, the filter 21A may not be provided with the diameter stop ring 21Ac, but may be provided with a flange portion projecting inwardly at the lower end portion of the body portion 22Aa of the support member 22A, and the lower end portion of the filter 21A supported by the flange portion. Good.

(Modification 1)
In the above embodiments, the upper ends of the filters 21 and 21A are open. However, as shown in FIGS. 14 (a) and 14 (b), the filter according to the present invention includes lid portions 21f and 21Af for closing the upper ends in addition to the cylindrical portions 21a and 21Aa and the bottom portion 21Ab.

Further, instead of the upper ends of the cylinder portions 21a and 21Aa being closed by the lid portions 21f and 21Af, openings 21h and 21Ah are formed on the side surfaces of the cylinder portions 21a and 21Aa. The openings 21h and 21Ah are formed so as to be positioned above the outlet 2b formed in the main body 2.

  Even when such filters 21 and 21A are used, the same effects as those of the above embodiments can be obtained. Further, when substantially the entire filter 21, 21A is clogged, rainwater can be guided from the openings 21h, 21Ah into the filters 21, 21A and discharged from the outlet 2b. Therefore, according to the filter devices 10 and 10A using such filters 21 and 21A, rainwater cannot be discharged from the outlet 2b even when the filters 21 and 21A are substantially clogged. The overflow of the filter 1 can be prevented.

  The filter devices 10 and 10A include lid portions 21f and 21Af. For this reason, when dust such as dead leaves flows into the inside of the filter 1 from the upper end opening, the dust can be prevented from entering the filters 21 and 21A.

As shown in FIGS. 15 (a) and 15 (b), the filter devices 10 and 10A according to the modified example 2 have the openings 21h and 21Ah in the modified example 1 formed by a mesh having a coarser mesh than the other parts. The distribution sections 21g and 21Ag are used.

  According to the filter devices 10 and 10A according to the second modification, the circulation parts 21g and 21Ag having coarser eyes than the other parts are not easily clogged. Therefore, even when substantially the entire filters 21 and 21A are clogged, rainwater can be guided from the circulation portions 21g and 21Ag to the inside of the filters 21 and 21A. Therefore, according to the filter devices 10 and 10A using such filters 21 and 21A, rainwater cannot be discharged from the outlet 2b even when the filters 21 and 21A are substantially clogged. The overflow of the filter 1 can be prevented.

  Further, the filter devices 10 and 10A according to the second modification also include the lid portions 21f and 21Af as in the first modification. For this reason, when dust such as dead leaves flows into the inside of the filter 1 from the upper end opening, the dust can be prevented from entering the filters 21 and 21A.

As shown in FIGS. 16A and 16B, the filter device 10A according to the modified example 3 includes the filter 21A of the filter device 10A according to the second embodiment and the modified example 1 (not shown but the modified example 2 is also the same). Thus, it is possible to attach to the outlet 2b without using the support member 22A. The filter device 10A shown in FIG. 16A is a modification of the filter 21A of the filter device 10A according to the second embodiment, and the filter device 10A shown in FIG. This is a modification of the filter 21A of the filter device 10A according to the modified example 2 (not shown).

  A cylindrical insertion portion 21Ai is formed on the side of the filter 21A of the filter device 10A according to the third modification. The insertion portion 21Ai is formed so as to be able to be inserted into the outlet 2b. Specifically, the outer diameter is formed to be substantially equal to or slightly smaller than the inner diameter of the outflow pipe 12. According to the filter device 10A according to the modification 3, the filter 21A can be directly attached to the outlet 2b by inserting the insertion portion 21Ai into the outlet 2b.

  According to such a filter device 10A, the filter 21A can be attached to the outlet 2b without a support member. Therefore, the number of parts can be reduced. Further, the filter 21A can be attached and detached by a simple operation. Thereby, inspection work and maintenance work can be facilitated.

  The insertion portion 21Ai may be fixed simply by being inserted into the outlet 2b, or may be fixed by providing an engaging portion or the like and engaging with the outflow pipe 12 or the like. .

(Modification 4)
In the first and second embodiments, the filters 21 and 21A and the support members 22 and 22A are attached to the filters 1 and 1A using the bucket 3 in which the handle 6 having a function as an attachment member is formed. However, as shown in FIGS. 17 (a) and 17 (b), without using the bucket 3, the first and second filter bodies 1 and 1A have the concave slide rails 6e and 6e of the handle 6 in the first and second embodiments. Similar concave slide rails 26e, 26e may be formed and attached.

  Specifically, the mounting is performed by engaging the convex slide rails 22g and 22g of the flanges 22d and 22Ad of the support members 22 and 22A and the concave slide rails 26e and 26e of the main body 2 first. Even in such a case, the filters 21 and 21A can be attached to the outlet 2b, and the same effects as those of the first and second embodiments can be achieved. 17A and 17B, the concave slide rails 26e and 26e are shown larger than the convex slide rails 22g and 22g for convenience of illustration, but the concave slide rails 26e and 26e and the convex slide are shown. The rails 22g and 22g are formed to have substantially the same size so that they can be engaged.

(Modification 5)
As shown in FIGS. 18A and 18B, in the filter devices 10 and 10A according to the modified example 5, the filters 21 and 21A have relatively coarser filters 21x and 21Ax, and the filters 21x and 21Ax It is composed of fine filters 21y and 21Ay. The filters 21x and 21Ax are formed above the filters 21y and 21Ay. The filter 21 of the filter devices 10 and 10A according to the first and second embodiments may be as in the fifth modification. The filters 21 and 21A are preferably attached so that the filters 21x and 21Ax are located above the upper end of the outlet 2b.

  Even with such filter devices 10 and 10A, the surface areas of the filters 21 and 21A can be significantly increased as compared with the conventional ones. Therefore, for example, even if the level of rainwater rises because the filters 21y and 21Ay on the lower side of the filters 21 and 21A are clogged and impervious to rainwater, the upper filters 21x and 21Ax capture dust and collect rainwater. It becomes possible to flow to the outlet 2b side. As a result, the maximum amount of dust can be greatly increased. Therefore, the frequency of maintenance, which has been frequently performed in the past, can also be reduced by the filter devices 10 and 10A.

  In addition, although illustration is abbreviate | omitted, the filters 21 and 21A may be provided with the cover parts 21f and 21Af (refer FIG. 14 (a), (b)) which closes the upper end of upper filter 21x, 21Ax. . In such a case, even if the fine filters 21y and 21Ay on the lower side are clogged, rainwater can flow from the upper filters 21x and 21Ax on the coarser side toward the outlet 2b. Therefore, since rainwater cannot be discharged from the outlet 2b, it is possible to prevent the filter 1 and 1A from overflowing.

  In addition, the filter 21 which concerns on the modification 6 should just be provided with the trunk | drum 21a and the insertion part 21b, and the specific shape is not limited to the said shape. The filter 21 shown in FIG. 19 is formed in a shape such that a single cylindrical body is bent in the middle, but the shape of the filter 21 may be other shapes. For example, a shape in which a hole is formed in the side surface of the cylindrical trunk portion 21a extending in the vertical direction and a cylindrical insertion portion 21b extending in the horizontal direction is inserted into the hole may be employed.

  In each of the above-described embodiments and modifications, the filters 21 and 21A are made of metal. However, the material of the filters 21 and 21A is not limited to metal. For example, resin may be used. Even in this case, it is needless to say that the above effects can be achieved. Further, the filters 1 and 1A may be made of resin or concrete. Furthermore, the support members 22 and 22A described above are merely examples of the support member according to the present invention, and are not limited to the form. The supporting members 22 and 22A may take any form as long as they support the filters 21 and 21A and can be attached to the mounting member or the filter 1 and 1A.
