Description

本発明は、フィルターに関し、詳しくは縦置きタイプのフィルターを掃除する際にメッシュ部に捕集されたホコリが剥がれ落ちるのを防止しようとする技術に関するものである。   The present invention relates to a filter, and more particularly to a technique for preventing dust collected in a mesh portion from peeling off when cleaning a vertical filter.

従来より、脱臭ダクトの横長開口部から脱臭ダクト内に抜き差しされる横置きタイプのフィルターが知られている（例えば、特許文献１、特許文献２参照）。   Conventionally, a horizontal type filter that is inserted and removed from a horizontally long opening of a deodorizing duct into the deodorizing duct is known (see, for example, Patent Document 1 and Patent Document 2).

ところが、従来の横置きタイプのフィルター１´を、脱臭ダクトの縦長開口部から脱臭ダクト内に抜き差しされる縦置きタイプのフィルターとして用いた場合にあっては、図４（ａ）のように、従来のフィルター１´はメッシュ部２の吸い込み面２ａと外周枠部３の前端面３ａとの段差が小さいため、フィルター１´を掃除するために脱臭ダクトの縦長開口部１２´から取り出す際に、図４（ｂ）のように、メッシュ部２で捕集されているホコリ５が縦長開口部１２´の前端壁のハウジング１１部分に擦れて剥ぎ落されてしまい、脱臭ダクト内に溜まるようになる。これを放置しておくと、ホコリ５が脱臭部に詰まって脱臭性能が低下することから、脱臭ダクト内部を掃除する必要があり、掃除に手間がかかるという問題があった。
特開平１０−２１９７８８号公報 特開２００１−２６２６６３号公報 However, in the case where the conventional horizontally placed filter 1 ′ is used as a vertically placed type filter that is inserted into and removed from the vertically long opening of the deodorizing duct, as shown in FIG. Since the conventional filter 1 ′ has a small step between the suction surface 2 a of the mesh portion 2 and the front end surface 3 a of the outer peripheral frame portion 3, when taking out from the vertically long opening 12 ′ of the deodorizing duct in order to clean the filter 1 ′, As shown in FIG. 4 (b), the dust 5 collected by the mesh portion 2 is scraped off by the housing 11 portion of the front end wall of the vertically long opening portion 12 'and is accumulated in the deodorizing duct. . If this is left as it is, the dust 5 is clogged in the deodorizing part and the deodorizing performance is deteriorated. Therefore, it is necessary to clean the inside of the deodorizing duct, and there is a problem that it takes time for cleaning.
Japanese Patent Laid-Open No. 10-219788 JP 2001-262663 A

本発明は上記の従来の問題点に鑑みて発明したものであって、脱臭ダクトの縦長開口部からフィルターを取り出す際に、メッシュ部に捕集されたホコリが脱臭ダクト内に落ちるのを防止でき、掃除を容易に行なえるようにしたフィルターを提供することを課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and can prevent dust collected in the mesh portion from falling into the deodorization duct when the filter is taken out from the vertically long opening of the deodorization duct. It is an object of the present invention to provide a filter that can be easily cleaned.

前記課題を解決するために本発明は、脱臭ダクト１０の側面に設けた縦長開口部１２から脱臭ダクト１０内に抜き差し自在に挿入される縦置きタイプのフィルターであって、脱臭ダクト１０の上流側Ａから吸い込まれる空気中のホコリ５を捕集するメッシュ部２と、メッシュ部２の外周部を保持する外周枠部３とで構成され、メッシュ部２の吸い込み面２ａよりも上流側Ａに突出する外周枠部３の前端部を更に上流側Ａに突出させて、ホコリ５を溜めるスペースとなるホコリ溜め部４を外周枠部３のほぼ全周に亘って形成したことを特徴としている。   In order to solve the above-mentioned problem, the present invention is a vertically installed filter that is detachably inserted into a deodorizing duct 10 from a vertically long opening 12 provided on a side surface of the deodorizing duct 10. Consists of a mesh portion 2 that collects dust 5 in the air sucked from A and an outer peripheral frame portion 3 that holds the outer peripheral portion of the mesh portion 2, and protrudes upstream A from the suction surface 2 a of the mesh portion 2. Further, the front end portion of the outer peripheral frame portion 3 is further protruded to the upstream side A, and the dust reservoir portion 4 serving as a space for storing the dust 5 is formed over substantially the entire circumference of the outer peripheral frame portion 3.

このような構成とすることで、メッシュ部２の吸い込み面２ａがホコリ溜め部４のスペース分だけ外周枠部３の前端部よりも深く配置されるようになるので、フィルター１の取り出し時にメッシュ部２の吸い込み面２ａが縦長開口部１２の前端壁部分に擦られることがなくなり、メッシュ部２に捕集されたホコリ５が剥ぎ落されてしまうのを防止でき、また万が一、メッシュ部２のホコリ５が剥がれて落下した場合でも、外周枠部３に設けたホコリ溜め部４にホコリ５が溜められるので、脱臭ダクト１０内に落下することがなく、フィルター１の掃除を容易に行なうことができる。   By adopting such a configuration, the suction surface 2a of the mesh portion 2 is disposed deeper than the front end portion of the outer peripheral frame portion 3 by the space of the dust reservoir portion 4, so that the mesh portion is removed when the filter 1 is taken out. 2, the suction surface 2 a is not rubbed against the front end wall portion of the vertically long opening 12, and the dust 5 collected on the mesh portion 2 can be prevented from being peeled off. Even when 5 is peeled off and dropped, the dust 5 is stored in the dust storage portion 4 provided on the outer peripheral frame portion 3, so that it does not fall into the deodorizing duct 10 and the filter 1 can be easily cleaned. .

また上記ホコリ溜め部４の一部に、フィルター１が上下入れ間違い状態で縦長開口部１２に挿入されるのを防止するための誤挿入防止手段６を設けるのが好ましい。   Moreover, it is preferable to provide an erroneous insertion preventing means 6 for preventing the filter 1 from being inserted into the vertically long opening 12 in a state where the filter 1 is inserted up and down in a part of the dust reservoir 4.

このような構成とすることで、仮りにフィルター１の上下を間違えて挿入しようとしても、凹凸部６によって縦長開口部１２に挿入できなくなり、これにより、ホコリ溜め部４がメッシュ部２よりも下流側Ｂに位置してしまうという誤挿入を未然に防止できる。   By adopting such a configuration, even if the filter 1 is inserted upside down by mistake, it cannot be inserted into the vertically long opening 12 due to the concave and convex portions 6, so that the dust reservoir 4 is downstream of the mesh portion 2. It is possible to prevent an erroneous insertion of being located on the side B.

本発明に係る縦置きタイプのフィルターは、フィルターの外周枠部からホコリを溜めるスペースとなるホコリ溜め部を突設するという簡単な構成で、脱臭ダクトから引き出してフィルターを掃除する際に、メッシュ部にて捕集されたホコリが剥がれて脱臭ダクト内に落ちてしまうのを防止でき、また万が一、剥がれ落ちた場合でもホコリ溜め部に溜めることができるため、フィルターの掃除をきわめて容易に行なうことができる。   The vertical-type filter according to the present invention has a simple configuration in which a dust storage portion that serves as a space for storing dust from the outer peripheral frame portion of the filter is projected, and when the filter is pulled out from the deodorizing duct and cleaned, It is possible to prevent the dust collected in the chamber from peeling off and falling into the deodorizing duct, and even if it is peeled off, it can be stored in the dust reservoir so that the filter can be cleaned very easily. it can.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

便器に設置される温水洗浄便座には脱臭ダクト１０が付設されている。この脱臭ダクト１０は、図３（ａ）に示すように、集塵用プレフィルター１と、脱臭ハニカム１５と、ファン１６とがハウジング１１内のダクト通路に収納され、集塵用プレフィルター１よりも上流に、便器ボウル側に開口した吸い込み口１３が設けられ、ファン１６よりも下流に外部に開口した吐き出し口１４が設けられている。   A deodorizing duct 10 is attached to a warm water washing toilet seat installed in the toilet bowl. As shown in FIG. 3A, the deodorization duct 10 includes a dust collection prefilter 1, a deodorization honeycomb 15, and a fan 16 housed in a duct passage in the housing 11. In addition, a suction port 13 opened on the toilet bowl side is provided upstream, and a discharge port 14 opened outside is provided downstream of the fan 16.

上記集塵用プレフィルター１（以下「フィルター１」という。）は、脱臭ダクト１０のハウジング１１の側面に設けた縦長開口部１２から抜き差し自在とされる縦置きタイプのものであり、図２に示すように、吸い込み口１３から吸い込まれる空気中のホコリやゴミ等（以下、ホコリ５という。）を捕集するメッシュ部２と、メッシュ部２の外周部を保持する外周枠部３とで構成されている。図中の７は中桟である。さらに、外周枠部３の手前側の端部には縦長開口部１２に対する挿入深さを規制するためのストッパ用リブ８が設けられ、さらにその手前には、縦長開口部１２の外側に突出する取手９が設けられている。   The dust pre-filter 1 (hereinafter referred to as “filter 1”) is of a vertically placed type that can be freely inserted and removed from a vertically long opening 12 provided on the side surface of the housing 11 of the deodorizing duct 10. As shown, it is composed of a mesh part 2 that collects dust, dust, and the like (hereinafter referred to as dust 5) in the air sucked from the suction port 13, and an outer peripheral frame part 3 that holds the outer peripheral part of the mesh part 2. Has been. In the figure, 7 is a middle rail. Further, a stopper rib 8 for restricting the insertion depth with respect to the vertically long opening 12 is provided at the front end of the outer peripheral frame 3, and further protrudes outside the vertically long opening 12 in front of it. A handle 9 is provided.

ここで、本発明においては、図２（ｂ）、（ｃ）に示すように、メッシュ部２の吸い込み面２ａよりも上流側Ａに突出する外周枠部３の前端部を、更に上流側Ａに突出させて、ホコリ５を溜めるスペースとなるホコリ溜め部４を形成している。このホコリ溜め部４は外周枠部３のほぼ全周に亘って形成されている。これにより、メッシュ部２の吸い込み面２ａがホコリ溜め部４のスペースＳ分だけ外周枠部３の前端部分よりも深い位置（下流側Ｂの位置）に配置されるようになっている。このホコリ溜め部４は、フィルター１を脱臭ダクト１０の縦長開口部１２から取り出す際メッシュ部２からホコリ５の剥がれ落ちを防ぐ役割と、また万が一ホコリ５が剥がれてもホコリ５がフィルター１の外部に落下するのを防ぐ役割とを果す。   Here, in the present invention, as shown in FIGS. 2 (b) and 2 (c), the front end portion of the outer peripheral frame portion 3 protruding to the upstream side A from the suction surface 2 a of the mesh portion 2 is further connected to the upstream side A. The dust reservoir 4 is formed as a space for storing the dust 5. The dust reservoir 4 is formed over substantially the entire circumference of the outer peripheral frame 3. Thereby, the suction surface 2a of the mesh part 2 is arranged at a position deeper than the front end part of the outer peripheral frame part 3 by the space S of the dust reservoir part 4 (position on the downstream side B). The dust reservoir 4 serves to prevent the dust 5 from peeling off from the mesh portion 2 when the filter 1 is taken out from the vertically long opening 12 of the deodorizing duct 10, and even if the dust 5 is peeled off, the dust 5 remains outside the filter 1. It plays a role of preventing falling.

しかして、フィルター１の取り出し時にメッシュ部２の吸い込み面２ａが縦長開口部１２の前端壁に擦られてメッシュ部２に捕集されたホコリ５が剥ぎ落されてしまうことがなくなり、また万が一、メッシュ部２のホコリ５が剥がれて落下した場合でも、外周枠部３に設けたホコリ溜め部４にホコリ５が溜められるので、脱臭ダクト１０内に落下することがない。従って、ホコリ５が脱臭ダクト１０内に落ちて脱臭ハニカム１５に詰まるようなことがなくなり、脱臭ダクト１０内の掃除も不要となる。   Thus, when the filter 1 is taken out, the suction surface 2a of the mesh portion 2 is rubbed against the front end wall of the vertically long opening portion 12, and the dust 5 collected on the mesh portion 2 is not peeled off. Even when the dust 5 of the mesh part 2 is peeled off and dropped, the dust 5 is stored in the dust storage part 4 provided in the outer peripheral frame part 3, so that it does not fall into the deodorizing duct 10. Accordingly, the dust 5 does not fall into the deodorizing duct 10 and become clogged with the deodorizing honeycomb 15, and cleaning of the deodorizing duct 10 is not necessary.

しかも、外周枠部３にホコリ溜め部４となるスペースＳを設けることで、外周枠部３が肉厚となり、これにより、外周枠部３の強度、ひいてはフィルター１の強度を向上させることができる利点もある。   In addition, by providing the outer frame 3 with the space S to be the dust reservoir 4, the outer frame 3 is thickened, thereby improving the strength of the outer frame 3 and thus the strength of the filter 1. There are also advantages.

ところで、フィルター１を上下入れ間違えた場合は、ホコリ溜め部４がメッシュ部２よりも下流側Ｂに位置してしまい、ホコリ溜め部４として機能しなくなる。そこで、フィルター１の上下入れ間違いを防止するために、本発明では、ホコリ溜め部４の一部に誤挿入防止手段６を設けている。その一例として、図１、図２に示すように、ホコリ溜め部４の上端側に凹段部６ａを切欠形成している。この凹段部６ａは、脱臭ダクト１０の縦長開口部１２側に設けられた凸段部６ｂと対向している。これにより、フィルター１の上下を間違えて挿入しようとした場合は、縦長開口部１２側の凸段部６ｂがホコリ溜め部４の凹段部６ａ以外の部位に当たることで、フィルター１の挿入ができなくなり、挿入ミスを確実に防止できるようになる。なお、誤挿入防止手段６として凹凸形状ではなく、上下を表示するための目印などであってもよい。   By the way, when the filter 1 is inserted upside down, the dust reservoir 4 is positioned on the downstream side B of the mesh portion 2 and does not function as the dust reservoir 4. Therefore, in order to prevent erroneous insertion of the filter 1, in the present invention, erroneous insertion preventing means 6 is provided in a part of the dust reservoir 4. As an example, as shown in FIGS. 1 and 2, a concave step 6 a is cut out on the upper end side of the dust reservoir 4. The concave step portion 6 a faces the convex step portion 6 b provided on the side of the vertically long opening 12 of the deodorizing duct 10. As a result, if the filter 1 is to be inserted upside down, the filter 1 can be inserted because the convex step 6 b on the side of the vertically long opening 12 hits a portion other than the concave step 6 a of the dust reservoir 4. The insertion error can be reliably prevented. The erroneous insertion preventing means 6 may be a mark for displaying the upper and lower sides instead of the uneven shape.

本発明に係る縦置きタイプのフィルター１は、前記実施形態のような集塵用プレフィルターに適用されるだけでなく、脱臭用フィルターにも広く適用されるものである。   The vertically placed filter 1 according to the present invention is not only applied to the dust collecting pre-filter as in the above embodiment, but also widely applied to a deodorizing filter.
