Abstract

A filter dust removal device, provided with a casing, a filter part (3), a biasing part (4), a movable part (5), an anti-biasing part (6), and a stopping part (7). The casing has a cylindrical shape and has, in the interior space, an airflow path. The filter part (3) cleans air flowing through the airflow path at a cleaning position. The biasing part (4) biases the filter part (3) towards the downstream side of the cleaning position. The movable part (5) moves the filter part (3) to the downstream side on the basis of the biasing by the biasing part (4). The anti-biasing part (6) biases the filter part (3) to the upstream side against the biasing by the biasing part (4). The stopping part (7) stops the filter part (3) from moving farther upstream than the cleaning position. The anti-biasing part (6) moves the filter part (3) towards the upstream side by a reaction, in response to a cancellation of the action of the biasing by the biasing part (4), and causes the filter part (3) to collide with the stopping part (7).

First, a schematic configuration of the filter dust removal method according to the present invention will be described with reference to FIGS. 1 is a schematic perspective view of the filter dust remover according to the present invention, FIG. 2 is a side sectional view of the filter dust remover, FIG. 3A, FIG. 3B is a schematic view of the air passage seen from the downstream side, FIG. 4A, FIG. FIG. 4B is a view showing an example of a support and a filter, FIG. 5 is a schematic view showing an energized state, and FIG. 6 is a schematic view showing a state where the bias is released.
　フィルタ除塵装置は、例えば建物の屋外、または建物の壁近傍に設けられ、図示しない送風機の動作により、屋外の空気を屋内に給気する際の風路上に設けられる。フィルタ除塵装置は、図１～図６に示すように、筐体１と、フィルタ部３と、付勢部４と、可動部５と、反付勢部６と、抑止部７とを備えている。 The filter dust remover is provided, for example, outside the building or in the vicinity of a wall of the building, and is provided on the air path for supplying outdoor air indoors by the operation of a blower not shown. As shown in FIGS. 1 to 6, the filter dust remover includes a housing 1, a filter unit 3, a biasing unit 4, a movable unit 5, a counter biasing unit 6, and a suppressing unit 7. There is.
　筐体１は、筒形状であって内部空間に送風路１０を有し、フィルタ除塵装置の外郭を形成する。筐体１は、送風路１０における送風方向に対する垂直断面が、矩形形状を含む。ここで矩形形状を含むとは、完全な矩形形状でなくてもよいことを意味し、一部に矩形形状を有して少なくとも一つの辺（一辺）を含めばよい。例えば、図３Ａに示した矩形や、図３Ｂに示すような略アーチ型であっても矩形形状を含む。 The housing 1 has a tubular shape, has an air passage 10 in the inner space, and forms an outer shell of the filter dust removing device. The housing 1 has a rectangular cross section perpendicular to the air blowing direction in the air blowing passage 10. Here, including the rectangular shape means that it does not have to be a complete rectangular shape, and it is sufficient to have a rectangular shape in part and include at least one side (one side). For example, the rectangular shape shown in FIG. 3A or the substantially arched shape as shown in FIG. 3B includes a rectangular shape.
　送風路１０には、内部空間にフィルタ部３と、付勢部４と、可動部５と、反付勢部６と、抑止部７とが配置される。送風路１０は、上流側に位置する外部の空気を下流側に位置する例えば室内等の空間の内部へ送風するための風路である。なお、空気の流れは例えば下流に設けられた図示しない送風機により生成される。 A filter unit 3, a biasing unit 4, a movable unit 5, a counter biasing unit 6, and a restraining unit 7 are disposed in the inner space of the air passage 10. The blower passage 10 is an air passage for blowing the outside air located upstream, to the inside of a space such as a room located downstream. In addition, the flow of air is produced | generated by the not-shown fan provided downstream, for example.
　フィルタ部３は、送風路１０中に設けられ、送風路１０を流れる空気を通過させてこの空気に含まれる浄化対象物を浄化位置２にて捕集し、すなわち空気を浄化する。ここで浄化位置２とは、送風路１０上であってフィルタ８が空気を浄化する位置であり、筐体１の垂直断面を構成する矩形形状の一辺と一致する。フィルタ部３は、図４Ａ、図４Bに示すように、フィルタ８と支持体９とを備えている。 The filter unit 3 is provided in the air passage 10, and allows the air flowing through the air passage 10 to pass and collects the purification object contained in the air at the purification position 2, that is, the air is purified. Here, the purification position 2 is a position on the air passage 10 where the filter 8 purifies the air, and coincides with one side of the rectangular shape that constitutes the vertical cross section of the housing 1. The filter unit 3 includes a filter 8 and a support 9 as shown in FIGS. 4A and 4B.
　フィルタ８は、例えば捕集対象として比較的重量のある砂塵などを対象とする場合には、不織布などを素材としたものが利用される。横網と縦網を重ね合わせた構造では均一で目の細かいフィルタを構成することが困難であるが、細かな砂やホコリといった浄化対象物を取り除く場合には不織布が適している。 The filter 8 is made of, for example, a non-woven fabric as a target when, for example, sand and the like having a relatively heavy weight are to be collected. It is difficult to construct a uniform and fine-grained filter in the structure in which the horizontal mesh and the longitudinal mesh are superposed, but non-woven fabric is suitable for removing the object to be cleaned such as fine sand and dust.
　支持体９は、枠体部９１と、必要に応じて梁部９２とを備える。支持体９は、フィルタ部３の移動時におけるフィルタ８の変形を防ぐ。 The support 9 includes a frame portion 91 and a beam portion 92 as needed. The support 9 prevents the deformation of the filter 8 when the filter unit 3 moves.
　枠体部９１は、硬質素材で構成され、例えば図４Ａに示すように、フィルタ８の周囲を囲むことでフィルタ８を所定の形状、本実施の形態においては送風路１０の断面にほぼ一致させた矩形に維持し、すなわちフィルタ８の変形を防止する。 The frame portion 91 is made of a hard material, and for example, as shown in FIG. 4A, the filter 8 is made to substantially conform to a predetermined shape, in the present embodiment, the cross section of the air passage 10 by surrounding the filter 8. To keep the rectangular shape, i.e. to prevent the deformation of the filter 8.
　梁部９２は、フィルタ８の平面強度が比較的弱い場合、つまりフィルタ８が繊維質の場合や面積が大きい場合に、フィルタ８の中央部が風圧を受けることにより形状変化することを防止するために設けられる。梁部９２は、図４Ｂに示すように、例えば枠体部９１と同一素材で枠体部９１を縦方向や横方向に架橋することで、フィルタ８を複数の領域に分割する。フィルタ８を複数の領域に分割することで各領域にかかる風圧に対する耐性を高め、フィルタ部３としての躯体強度を高めることができる。 The beam 92 prevents the shape of the central portion of the filter 8 from being subjected to wind pressure when the planar strength of the filter 8 is relatively weak, that is, when the filter 8 is fibrous or has a large area. Provided in As shown in FIG. 4B, the beam portion 92 divides the filter 8 into a plurality of regions, for example, by bridging the frame portion 91 in the longitudinal direction or the lateral direction with the same material as the frame portion 91. By dividing the filter 8 into a plurality of regions, the resistance to the wind pressure applied to each region can be enhanced, and the strength of the housing as the filter unit 3 can be enhanced.
　付勢部４は、フィルタ部３を浄化位置２よりも下流側に付勢する。付勢部４は、動力、あるいは人力によりフィルタ部３を付勢する。本実施の形態では、付勢部４は、動力を備えている。すなわち、付勢部４は、モータ回転軸１６（回転軸）を有するモータ１７と、モータ回転軸１６に設けられたカム１８とを備えている。 The biasing unit 4 biases the filter unit 3 to the downstream side of the purification position 2. The biasing unit 4 biases the filter unit 3 by power or human power. In the present embodiment, the biasing unit 4 is provided with power. That is, the biasing unit 4 includes a motor 17 having a motor rotation shaft 16 (rotation shaft) and a cam 18 provided on the motor rotation shaft 16.
　モータ１７は、給電によりモータ回転軸１６を回動する。モータ１７は、送風路１０の上面に係止されて送風路１０の下流側に引き伸ばされ、例えば室内の電源に接続されて筐体１の下流側からモータ１７に電力を供給する電力供給線を備えた構成にしてもよい。例えばフィルタ除塵装置を設置する外壁付近において電源設備が設けられていない場合でも、送風路１０を介して例えば屋内の電源に接続が可能になる。このため、電源設備の新たな設置が不要となり、設置可能範囲の拡大が可能となる。また、送風路１０の上面に電力供給線を係止することにより、雨滴が電力供給線に接触する確率が下がる。即ち雨滴の送風路１０への侵入に対して電力供給線の耐性を高めることができる。なお、係止方法については特に特定せず、例えば被覆された電力供給線を単に接着や狭持により係止してもよいし、モールを利用してモールの内部空間に電力供給線を格納することで係止してもよい。 The motor 17 rotates the motor rotation shaft 16 by power feeding. The motor 17 is locked to the upper surface of the air passage 10 and extended to the downstream side of the air passage 10. For example, the motor 17 is connected to a power source in the room and supplies power to the motor 17 from the downstream side of the housing 1. You may make it the structure provided. For example, even when the power supply facility is not provided in the vicinity of the outer wall where the filter dust removal apparatus is installed, connection to, for example, the indoor power supply is possible via the air passage 10. For this reason, new installation of a power supply installation becomes unnecessary, and expansion of an installation possible range is attained. In addition, by locking the power supply line on the upper surface of the air passage 10, the probability of raindrops contacting the power supply line is reduced. That is, the resistance of the power supply line to the intrusion of raindrops into the air passage 10 can be enhanced. The method of locking is not particularly limited. For example, the coated power supply line may be locked simply by bonding or holding, or the power supply line may be stored in the interior space of the molding using the molding It may be locked.
　カム１８は、モータ回転軸１６を中心とした円形状の任意の方向に突起部分１９を有する形状をしている。カム１８が回転することにより、突起部分１９がフィルタ部３を下流側に付勢する。これにより、フィルタ部３は、可動部５を回転軸２３として下流側に傾倒する。 The cam 18 is shaped so as to have a projecting portion 19 in any direction of a circular shape centered on the motor rotation shaft 16. As the cam 18 rotates, the projecting portion 19 biases the filter portion 3 to the downstream side. As a result, the filter unit 3 tilts the movable unit 5 downstream as the rotation shaft 23.
　可動部５は、付勢部４による作用４１方向への付勢に基づいてフィルタ部３を浄化位置２から下流側に移動させる。可動部５は、図２、図３Ａ、図３Ｂに示すように、浄化位置２の一辺とフィルタ部３の一辺とを一致させてフィルタ部３を回転可能に軸支する回転軸２３として設けられる。可動部５は、付勢部４による付勢により、一辺を回転軸２３としてフィルタ部３の回転軸２３に対向する例えば辺を、下流側に傾倒させる。 The movable unit 5 moves the filter unit 3 from the purification position 2 to the downstream side based on the biasing in the direction of the action 41 by the biasing unit 4. As shown in FIGS. 2, 3A, and 3B, the movable portion 5 is provided as a rotation shaft 23 that rotatably supports the filter portion 3 with one side of the purification position 2 aligned with one side of the filter portion 3. . The movable portion 5 biases, for example, a side opposite to the rotation shaft 23 of the filter portion 3 with the one side as the rotation shaft 23 by the urging by the urging portion 4 toward the downstream side.
　反付勢部６は、付勢部４による付勢に対してフィルタ部３を上流側に付勢する。反付勢部６は、図５、図６に示すように、例えばばね２０などの弾性体として設けられる。反付勢部６は、可動部５によるフィルタ部３の下流側への移動（作用４１）に対して、ばね２０の反作用６１により、フィルタ部３を浄化位置２に引き寄せるよう、フィルタ部３を付勢する。反付勢部６は、付勢部４の付勢解除によって反付勢部６の付勢の方が強くなることで、可動部５を回転軸２３としてフィルタ部３を上流側に回転させる。そのため、筐体１は、送風路１０における送風方向に対する垂直な面が回転動作を阻害しないように上述の矩形形状１１を含み、浄化位置２は、矩形形状１１における任意の一辺と一致する。 The counter biasing unit 6 biases the filter unit 3 upstream with respect to biasing by the biasing unit 4. The anti-biasing portion 6 is provided as an elastic body such as a spring 20 as shown in FIGS. 5 and 6. The counter biasing unit 6 causes the filter unit 3 to draw the filter unit 3 to the purification position 2 by the reaction 61 of the spring 20 against the downstream movement (action 41) of the filter unit 3 by the movable unit 5. Energize. The anti-biasing unit 6 rotates the filter unit 3 upstream with the movable unit 5 as the rotation shaft 23 because the biasing of the reversely-biasing unit 6 becomes stronger due to the release of the biasing unit 4. Therefore, the housing 1 includes the rectangular shape 11 described above so that the surface perpendicular to the air blowing direction in the air blowing passage 10 does not inhibit the rotation operation, and the cleaning position 2 coincides with any one side in the rectangular shape 11.
　抑止部７は、浄化位置２よりも上流側へのフィルタ部３の移動を抑制する。抑止部７は、浄化位置２にて送風路１０の内周に、内周側に突出するリブ或いは突部として設けられる。抑止部７は、反付勢部６によるフィルタ部３の上流側への移動に対して、浄化位置２においてフィルタ部３の支持体９への接触、つまりフィルタ部３が抑止部７に衝突することにより、フィルタ部３の上流側への移動を止める。 The suppression unit 7 suppresses the movement of the filter unit 3 to the upstream side of the purification position 2. The deterring portion 7 is provided on the inner periphery of the air passage 10 at the purification position 2 as a rib or a protrusion projecting to the inner peripheral side. The restraint unit 7 contacts the support 9 of the filter unit 3 at the purification position 2 against the movement of the filter unit 3 to the upstream side by the reverse biasing unit 6, that is, the filter unit 3 collides with the restraint unit 7 Thus, the movement of the filter unit 3 to the upstream side is stopped.
　以上が、本実施の形態に係るフィルタ除塵装置の概略構成である。 The above is a schematic structure of the filter dust removal apparatus according to the present embodiment.
　続いて、本実施の形態に係るフィルタ除塵装置の動作について説明する。 Subsequently, the operation of the filter dust removal apparatus according to the present embodiment will be described.
　付勢部４に給電されると、図５に示すように、フィルタ部３が、付勢部４による作用４１により付勢され可動部５を回転軸２３として下流側に回動する。 When power is supplied to the biasing unit 4, as shown in FIG. 5, the filter unit 3 is biased by the action 41 of the biasing unit 4 and rotates the movable unit 5 downstream as the rotary shaft 23.
　次に、カム１８がフィルタ部３を通過することによって、付勢部４の付勢が解除される。付勢部４による付勢が解除されると、反付勢部６の反作用６１のみがフィルタ部３に作用するために、フィルタ部３が可動部５を介して上流側に移動し、フィルタ部３の支持体９、具体的には枠体部９１を抑止部７に衝突させる。ここで、送風方向は、上流側から下流側であり、捕集された浄化対象物、例えば粉塵はフィルタ８の上流側の面で集塵されている。このため、下流側からフィルタ部３を抑止部７に衝突させることでフィルタ８に衝撃を伝播させ、フィルタ８で捕集された粉塵を上流側へ叩き落とすことでフィルタ８の除塵を行うことができる。付勢部４への給電を例えば定期的に行なうことで、フィルタ８のメンテナンス頻度を抑制、または不用とすることができる。 Next, when the cam 18 passes through the filter unit 3, the biasing of the biasing unit 4 is released. When the biasing by the biasing unit 4 is released, only the reaction 61 of the counter biasing unit 6 acts on the filter unit 3, the filter unit 3 moves upstream through the movable unit 5, and the filter unit The supporting member 9 of 3, specifically the frame portion 91, is made to collide with the suppressing portion 7. Here, the blowing direction is from the upstream side to the downstream side, and the collected purification object, for example, dust is collected on the surface on the upstream side of the filter 8. For this reason, colliding the filter unit 3 with the suppression unit 7 from the downstream side propagates an impact to the filter 8 and strikes off the dust collected by the filter 8 to the upstream side to remove the dust of the filter 8 it can. By supplying power to the biasing unit 4 regularly, for example, the maintenance frequency of the filter 8 can be suppressed or eliminated.
　以上のように、フィルタ除塵装置について、フィルタ部３を移動させ、抑止部７に衝突させることで、フィルタ部３からフィルタ８へ衝撃が伝播する。これにより、上流側に向いた衝撃力が粉塵に伝えられて、集塵されたフィルタ８の粉塵が除去される。そのため、長期使用においてフィルタ８が詰まることで圧力損失が上がることを軽減し、長期間の使用が可能となる。 As described above, in the filter dust removal apparatus, by moving the filter unit 3 and causing the filter unit 7 to collide with the filter unit 3, an impact is transmitted from the filter unit 3 to the filter 8. Thereby, the impact force directed to the upstream side is transmitted to the dust, and the dust of the collected filter 8 is removed. Therefore, in the long-term use, clogging of the filter 8 reduces pressure loss and enables long-term use.
　（実施の形態２）
　本実施の形態では、実施の形態１とは異なる点に付いてのみ説明する。 Second Embodiment
In the present embodiment, only differences from Embodiment 1 will be described.
　なお、実施の形態１では付勢部４が動力を有する場合について説明したのに対し、本実施の形態では、人力によりフィルタ８の除塵を行うことができる構成について説明する。 In addition, although Embodiment 1 demonstrated the case where the biasing part 4 had motive power, in this Embodiment, the structure which can remove the dust of the filter 8 by human power is demonstrated.
　なお図７は、手動のフィルタ除塵装置の付勢時の状態を示す概略構成図、図８は、手動のフィルタ除塵装置の付勢解除時の状態を示す概略構成図である。 FIG. 7 is a schematic configuration view showing a state of the manual filter dust removing device at the time of biasing, and FIG. 8 is a schematic configuration view showing a manual filter dust removing device at the time of releasing the bias.
　付勢部４ｂは、付勢部４ｂを介して人力によりフィルタ部３を付勢する操作部を有している。付勢部４ｂは、フィルタ部３の浄化位置２と対向する辺上に、引き紐１２として固定されている。 The biasing unit 4 b includes an operation unit that biases the filter unit 3 manually by means of the biasing unit 4 b. The biasing portion 4 b is fixed as a drawstring 12 on the side opposite to the purification position 2 of the filter portion 3.
　反付勢部６ｂは、支持紐１３と、滑車１４と、錘部１５とを備える。 The counter biasing unit 6 b includes a support cord 13, a pulley 14, and a weight 15.
　支持紐１３は、紐であり、フィルタ部３の浄化位置２と対向する辺上に、使用者が引き紐１２とは逆方向の上流側に牽引できるように固定された構造を有している。 The support cord 13 is a cord and has a structure fixed on the side of the filter unit 3 opposite to the purification position 2 so that the user can pull it to the upstream side in the direction opposite to the draw cord 12 .
　滑車１４は、抑止部７の上面に設けられ、支持紐１３が渡される。 The pulley 14 is provided on the upper surface of the restraining portion 7 and the support cord 13 is passed.
　錘部１５は、フィルタ部３側とは異なる支持紐１３の先端に設けられ、フィルタ部３を上流側に付勢する。 The weight part 15 is provided at the tip of the support cord 13 different from the filter part 3 side, and biases the filter part 3 to the upstream side.
　使用者は、引き紐１２を鉛直下方に牽引することで、フィルタ部３を付勢する。使用者が引き紐１２から手を離すことで、付勢部４ｂによる付勢を解除すると、錘部１５の引力が、滑車１４を介してフィルタ部３に伝達され、可動部５を回転軸２３として、フィルタ部３が浄化位置２に向かって上流側に回転する。そして、抑止部７にフィルタ部３が衝突することで、フィルタ８に衝撃が伝播し、捕集された粉塵が上流側へ叩き落とされる。ゆえに、電気を使用せずフィルタに補修された粉塵を除去する効果を得ることが可能となり、フィルタ８は、電気を使用できない環境下においても、性能を回復しながら長期間の使用が可能となる。 The user pulls the pull cord 12 vertically downward to bias the filter unit 3. When the user releases the urging by the urging portion 4b by releasing the hand from the draw cord 12, the attractive force of the weight portion 15 is transmitted to the filter portion 3 through the pulley 14, and the movable portion 5 is rotated about the rotation shaft 23 As a result, the filter unit 3 rotates upstream toward the purification position 2. Then, when the filter unit 3 collides with the suppressing unit 7, an impact is transmitted to the filter 8, and the collected dust is knocked off to the upstream side. Therefore, it is possible to obtain the effect of removing dust repaired by the filter without using electricity, and the filter 8 can be used for a long time while recovering performance even in an environment where electricity can not be used. .
　（変形例）
　実施の形態１、実施の形態２においては、可動部５が回転軸となる例について説明した。しかしながら、可動部５は回転軸である必要はない。つまり可動部５を、例えば図９及び図１０に示すように、送風路１０の上下位置にてフィルタ部３を、送風路１０内を上流の浄化位置２から下流へ及び下流から上流へ、送風路１０に対してフィルタ８を垂直に保った状態でスライド可能に挟み込む構造としてもよい。なお、付勢部４ｃや反付勢部６ｃの構造については、実施の形態１や実施の形態２のいずれを採用しても良い。 (Modification)
In the first embodiment and the second embodiment, the example in which the movable portion 5 is the rotation axis has been described. However, the movable part 5 does not have to be a rotating shaft. That is, as shown in, for example, FIGS. 9 and 10, the movable portion 5 is ventilated in the filter section 3 at the upper and lower positions of the air passage 10, in the air passage 10 from the upstream purification position 2 downstream and downstream from upstream. The filter 8 may be slidably held in a state in which the filter 8 is maintained perpendicular to the passage 10. Note that any of the first embodiment and the second embodiment may be adopted as the structure of the biasing portion 4c and the counter biasing portion 6c.
　なお図９は、付勢部４がフィルタ部３を付勢していない状態を示し、図１０は、付勢部４がフィルタ部３を付勢している状態を示す。 Note that FIG. 9 shows a state in which the urging unit 4 does not urge the filter unit 3, and FIG. 10 shows a state in which the urging unit 4 urges the filter unit 3.
　また、実施の形態１では、図１１Ａに示すように回転軸を鉛直方向下側に設けているが、図１１Ｂに示すように鉛直方向上側に設けても良い。 Further, in the first embodiment, the rotation axis is provided on the lower side in the vertical direction as shown in FIG. 11A, but may be provided on the upper side in the vertical direction as shown in FIG. 11B.
　図１１Ａに示すように、可動部５の回転軸２３を、矩形形状１１における鉛直方向下側の一辺２１に設けた場合には、フィルタ部３を付勢した際にフィルタ８で捕集された粉塵が風路内に侵入するのを防ぐことが可能である。 As shown in FIG. 11A, when the rotary shaft 23 of the movable portion 5 is provided on one side 21 of the rectangular shape 11 on the lower side in the vertical direction, the filter 8 is trapped when it is energized. It is possible to prevent dust from entering the air path.
　他方、図１１Ｂに示すように、可動部５の回転軸２３を、矩形形状１１における鉛直方向上側の一辺２２に設けた場合には、粉塵の除去効率がよくなる場合がある。つまり、砂漠地帯などで粉塵が砂塵などある程度重量が大きい場合や集塵対象物が昆虫などの場合、集塵対象物は、重力の作用を受けてフィルタの下方に付着しやすい。そして、回転軸２３を鉛直方向上側に設けることで、フィルタの下方は、回転軸から離れているため、衝突時の衝撃が大きくなる。従って、フィルタの、重力によって溜まり易い鉛直方向下側に捕集された集塵対象物は、この構成により、より大きな衝撃力により除去されやすい。 On the other hand, as shown in FIG. 11B, when the rotary shaft 23 of the movable portion 5 is provided on one side 22 of the rectangular shape 11 on the upper side in the vertical direction, the dust removal efficiency may be improved. That is, in the case of a desert area or the like, when the dust is a certain amount of weight such as dust, or when the object to be collected is an insect or the like, the object to be collected tends to adhere under the filter under the action of gravity. Further, by providing the rotary shaft 23 on the upper side in the vertical direction, the lower part of the filter is separated from the rotary shaft, so the impact at the time of collision becomes large. Therefore, the object to be collected which is collected on the vertically lower side of the filter, which tends to be accumulated by gravity, is easily removed by a larger impact force by this configuration.
　＜実施の形態の概要＞
　本発明に係るフィルタ除塵装置は、筐体と、フィルタ部と、付勢部と、可動部と、反付勢部と、抑止部と、を備える。筐体は、筒形状であって内部空間に送風路を有する。フィルタ部は、送風路を流れる空気を浄化位置にて浄化する。付勢部は、フィルタ部を浄化位置よりも下流側に付勢する。可動部は、付勢部による付勢に基づいてフィルタ部を下流側に移動させる。反付勢部は、付勢部による付勢に対してフィルタ部を上流側に付勢する。抑止部は、浄化位置よりも上流側へのフィルタ部の移動を抑止する。反付勢部は、付勢部による付勢の作用の解除に対して反作用によりフィルタ部を上流側に移動させてフィルタ部を抑止部に衝突させる。 <Overview of Embodiment>
A filter dust removal apparatus according to the present invention includes a housing, a filter unit, a biasing unit, a movable unit, a counter biasing unit, and a suppressing unit. The housing has a tubular shape and has an air passage in the internal space. The filter unit purifies the air flowing through the air passage at the purification position. The biasing portion biases the filter portion downstream of the cleaning position. The movable portion moves the filter portion downstream based on the biasing by the biasing portion. The counter biasing section biases the filter section upstream with respect to biasing by the biasing section. The deterring unit restrains the movement of the filter unit upstream of the purification position. The counter biasing unit moves the filter unit to the upstream side by a reaction against the release of the biasing action of the biasing unit, and causes the filter unit to collide with the suppressing unit.
　これにより、フィルタ部からフィルタへ衝撃が伝播し、送風路の上流側に向いた衝撃力を伝えて、集塵されたフィルタの粉塵が除去される。これにより、長期使用でフィルタが詰まることで圧力損失が上がることを軽減し、長期間の使用が可能となる。 Thereby, an impact is transmitted from the filter portion to the filter, and an impact force directed to the upstream side of the air passage is transmitted to remove dust of the collected filter. This reduces pressure loss due to clogging of the filter during long-term use, enabling long-term use.
　また、フィルタ部は、空気を通過させて空気に含まれる浄化対象物を捕集するフィルタと、フィルタ部の移動時におけるフィルタの変形を防ぐための支持体とを備え、抑止部は、浄化位置において支持体と衝突する構成としてもよい。 Also, the filter unit includes a filter that passes air and collects the purification target contained in the air, and a support for preventing deformation of the filter when the filter unit moves, and the suppression unit is a cleaning position. And the support may collide with the support.
　これにより、風の力によって、フィルタ形状が変化し風路に対して隙間が発生することを防ぐことができ、送風路を通過する風を確実にフィルタに通すことが可能となり、集塵する効果を高めることが出来る。 As a result, it is possible to prevent the filter shape from changing due to the force of the wind and the generation of a gap with respect to the air passage, and it becomes possible to reliably pass the air passing through the air passage through the filter. Can be enhanced.
　また、筐体は、送風路における送風方向に対する垂直断面が矩形形状を含み、矩形形状における一辺を浄化位置とし、可動部は、浄化位置とフィルタ部の一辺とを一致させてフィルタ部の回転軸として設けられ、付勢部は、付勢により可動部を回転軸としてフィルタ部を下流側に傾倒させる構成にしてもよい。 In the casing, the cross section perpendicular to the air blowing direction in the air blowing path includes a rectangular shape, one side of the rectangular shape is a cleaning position, and the movable portion matches the cleaning position with one side of the filter portion to rotate the filter shaft The biasing portion may be configured to tilt the filter portion downstream with the movable portion as the rotation axis by biasing.
　これにより、モーメント力によって衝突の衝突力を高め、効率的に捕集した粉塵を除去できるため、より長期間の使用が可能となる。 As a result, the moment force can increase the impact force of the collision, and the collected dust can be efficiently removed, thereby enabling long-term use.
　また、反付勢部は、フィルタ部を浄化位置に引き寄せる弾性体もしくは、重力を利用してフィルタ部を上流側に付勢する錘部である構成でもよい。 In addition, the counter biasing unit may be an elastic body that draws the filter unit toward the cleaning position, or a weight unit that biases the filter unit upstream using gravity.
　これにより、付勢部の付勢を解除することで、力学的に付勢部よりも反付勢部の付勢が強くなるため、反付勢の力を加えることなく、フィルタ部が抑止部に衝突する。 As a result, by releasing the biasing of the biasing unit, the biasing of the anti-biasing portion is mechanically stronger than the biasing portion, so that the filter unit can be prevented from applying the force of the reverse biasing. To clash.
　また、付勢部は、人力にてフィルタ部を下流側に付勢するための操作部である構成でもよい。 The biasing unit may be an operation unit for manually biasing the filter unit downstream.
　これにより、電気を使用せずにフィルタに捕集された粉塵を除去することができ、電気を使用できない環境下においても、性能を復帰しながら長期的に使用することが可能である。 As a result, dust collected by the filter can be removed without using electricity, and even in an environment where electricity can not be used, it can be used for a long time while recovering performance.
　また、付勢部は、回転軸を有するモータと、回転軸に設けられたカムとを備え、カムの回転によりフィルタ部を浄化位置から傾倒させる構成でもよい。 Further, the biasing unit may include a motor having a rotating shaft and a cam provided on the rotating shaft, and may rotate the cam to tilt the filter unit from the cleaning position.
　これにより、人による操作の手間を低減して、自動でフィルタに捕集された粉塵が除去されるため容易に性能回復が可能である。 As a result, it is possible to easily restore the performance because the time and labor of the operation by a person can be reduced and the dust collected by the filter can be removed automatically.
　また、定期動作を行う制御基板などの電気的な操作を行うことにより、メンテナンスを忘れることなく長期間の使用が可能となる。 In addition, by performing an electrical operation such as a control board that performs a periodic operation, long-term use can be realized without forgetting maintenance.
　また、回転軸は、矩形形状における鉛直方向下側の一辺に設けられた構成でもよい。 The rotation axis may be provided on one side of the rectangular shape on the lower side in the vertical direction.
　これにより、フィルタ部を前記送風路の下流側に付勢時、フィルタの捕集面は反重力方向に傾倒するため、捕集粉塵が送風路内に落下しない効果がある。 As a result, when the filter portion is urged to the downstream side of the air flow path, the collection surface of the filter is inclined in the direction of antigravity, so that the collected dust does not fall into the air flow path.
　また、回転軸は、矩形形状における鉛直方向上側の一辺に設けられた構成でもよい。 The rotation axis may be provided on one side of the rectangular shape on the upper side in the vertical direction.
　これにより、モーメント力によってフィルタ部の鉛直方向下側の衝撃力が強くなる。そのため、粉塵が溜まりやすいフィルタの鉛直方向下側に衝撃力の作用点が配置されるので、除塵量が大きくなる効果がある。 As a result, the impact force on the lower side in the vertical direction of the filter portion is strengthened by the moment force. Therefore, since the point of action of the impact force is disposed on the lower side in the vertical direction of the filter where dust tends to collect, there is an effect of increasing the amount of dust removal.
　また、モータは送風路の上面に係止されて送風路の下流側に引き伸ばされ、筐体の下流側からモータに電力を供給する電力供給線を備えた構成にしてもよい。 Further, the motor may be configured to be provided with a power supply line that is locked to the upper surface of the air flow path and drawn to the downstream side of the air flow path to supply power to the motor from the downstream side of the housing.
　これにより、前記フィルタ除塵装置を設置する外壁付近において電源設備が設けられていない場合でも、送風路を介して例えば屋内の電源に接続が可能になるため、電源設備の新たな設置が不要となり、設置可能範囲の拡大が可能となる。また、送風路の上面に係止することにより、雨滴が電力供給線に接触する確率を下げ、即ち雨滴の送風路への侵入に対して電力供給線の耐性を高めることができる。 As a result, even when the power supply equipment is not provided near the outer wall where the filter dust removal apparatus is installed, connection to the indoor power supply, for example, is possible via the air passage, so that new installation of the power supply equipment becomes unnecessary. It is possible to expand the installable range. Further, by locking on the upper surface of the air passage, the probability of raindrops coming into contact with the power supply line can be reduced, that is, the resistance of the power supply line to intrusion of raindrops into the air passage can be enhanced.
　本発明に係るフィルタ除塵装置は、細かな砂やホコリといった粉塵を集塵することが可能であり、長期的使用においてのメンテナンス頻度を抑制するフィルタ除塵装置として有用である。 The filter dust remover according to the present invention can collect dust such as fine sand and dust, and is useful as a filter dust remover that suppresses maintenance frequency in long-term use.
