Description

本発明は、調理中に発生する汚染空気（汚染物質）を吸い込み捕集して屋外に排気または汚染空気を清浄化した後に室内（キッチン）に戻すレンジフードに係り、特に、汚染空気中に含まれている油脂分や塵埃など汚れを分離回収するフィルタ部材の清掃を行うフィルタ清掃装置を備えたレンジフードに関する。   The present invention relates to a range hood that sucks and collects contaminated air (contaminant) generated during cooking and returns it to the room (kitchen) after exhausting the exhaust air or cleaning the contaminated air outdoors, and is particularly included in the contaminated air. The present invention relates to a range hood provided with a filter cleaning device that cleans a filter member that separates and collects dirt such as oil and fat and dust.

レンジフードには、調理中に加熱調理器や調理鍋などから舞い上がってくる廃ガスや油煙などの汚染空気を吸い込み捕集するために略下向きに開口させた吸込み口（捕獲空間）が設けられている。また、吸込み口から吸い込み捕集された汚染空気を、排気ダクトを介して屋外に排気する吐出し口に至る内部の排気風路には油脂分や塵埃などの汚れを汚染空気から分離回収（捕獲）するためのフィルタ部材が設けられている。   The range hood is provided with a suction port (capture space) that is opened downward to suck in and collect polluted air such as waste gas and oil smoke that rises from a cooking device or cooking pan during cooking. Yes. In addition, the polluted air sucked and collected from the suction port is separated and collected (captured) from the contaminated air in the internal exhaust air passage leading to the discharge port that exhausts the air through the exhaust duct to the outside. ) Is provided.

そして、近年では、使用者が定期的に行っているフィルタ部材の清掃作業の軽減、つまり、汚染空気から分離回収されてフィルタ部材の表面などにこびり付くように付着している頑固な油脂分などを取り除くなどの、面倒で手間の掛かる清掃作業を軽減する目的で、油脂分などの付着物をフィルタ部材から機械的などの動きによって拭き取るように取り除くフィルタ清掃装置を備えたレンジフードが提案されている（例えば、特許文献１などを参照）   In recent years, the filter member cleaning work regularly performed by the user has been reduced, that is, the stubborn oil and fat components that have been separated and collected from the contaminated air and adhered to the surface of the filter member and the like. In order to reduce cumbersome and time-consuming cleaning work, such as removing etc., a range hood with a filter cleaning device that removes deposits such as oil and fat from the filter member by mechanical movement is proposed (See, for example, Patent Document 1)

特開２００６−２９２２４８号公報（段落番号００２６、および図１参照）Japanese Patent Laying-Open No. 2006-292248 (see paragraph number 0026 and FIG. 1)

しかしながら、特許文献１に記載の従来技術では、フィルタ部材の表面に接しながら移動するブラシ（汚れ拭取り手段）によって、フィルタ部材に付着する汚れを取り除く構成を採用しているために、フィルタ部材から取り除かれた汚れがブラシの植毛繊維の間に入り込んでしまう。特に、取り除かれた油脂分が植毛繊維の間に入り込んで固まり、ひいては、汚れをフィルタ部材の表面から取り除くブラシ本来の拭取り作用、所謂清掃機能が低下してしまうおそれがある。   However, in the prior art described in Patent Document 1, since a configuration in which dirt attached to the filter member is removed by a brush (dirt wiping means) that moves while in contact with the surface of the filter member is employed, The removed dirt enters between the flocked fibers of the brush. In particular, the removed oil and fat may enter and solidify between the flocked fibers, and as a result, the original wiping action of the brush for removing dirt from the surface of the filter member, so-called cleaning function, may be reduced.

また、従来技術では、使用とともに植毛繊維の間に油脂分が徐々に堆積し、最悪の場合には植毛繊維の間に入り込んだ油脂分によって植毛繊維同士が結合してしまうなどのブラシ自体が目詰まりを引き起す。
そのために、ブラシそのものを定期的に取り外して、植毛繊維の間に入り込んだ油脂分などの汚れを取り除く清掃を必要とするばかりか、取り除くことができずに、新しいものと交換せざる得ない状態を招くなどの取扱い上の問題が有していた。 In the prior art, oil and fat gradually accumulates between the flocked fibers with use, and in the worst case, the brush itself is such that the flocked fibers are bonded by the oil and fat that has entered between the flocked fibers. Causes clogging.
Therefore, it is necessary not only to remove the brush itself periodically to remove dirt such as oil and fat that has entered between flocked fibers, but also to be able to remove it and replace it with a new one. There was a problem in handling such as inviting.

そこで、本出願人は、このような特許文献１が有する問題を解消し、清掃機能を低下させることなく長期にわたり継続的に使用することを可能として、使用者に対するメンテナンスなどを大幅に軽減することを実現したフィルタ清掃装置を備えたレンジフードを先に提案している（特願２０１０−１０４５９４号参照）。   Therefore, the present applicant solves the problems of Patent Document 1, makes it possible to continuously use for a long time without deteriorating the cleaning function, and greatly reduces maintenance for the user. Has previously proposed a range hood equipped with a filter cleaning device (see Japanese Patent Application No. 2010-104594).

ところで、本出願人が先に提案したフィルタ清掃装置に適用されているフィルタ部材は、排気風路の排気上流側と排気下流側に面するフィルタ両面に通じる無数の通気孔を平面的に開口点在させた、所謂パンチングメタルフィルタである。
一方、汚染空気から分離回収されてフィルタ面などに付着した油脂分や塵埃などの汚れを掻き落とすように取り除く付着物除去部材は、適宜の弾性を有する不燃性材料によってフィルタ面に平面的に圧接させる略平面板状に形成されている。 By the way, the filter member applied to the filter cleaning device previously proposed by the applicant of the present invention is a planar opening point of innumerable ventilation holes leading to both sides of the filter facing the exhaust upstream side and the exhaust downstream side of the exhaust air passage. This is a so-called punching metal filter.
On the other hand, an adhering substance removing member that is separated and recovered from contaminated air and removes dirt such as oil and fat and dust adhering to the filter surface is pressed flat against the filter surface with an appropriate non-combustible material. It is formed in a substantially flat plate shape.

そのために、本出願人が先に提案しているフィルタ清掃装置を備えたレンジフードでは、調理後などにおいてフィルタ部材を駆動回転させて油脂分や塵埃などの汚れをフィルタ面から取り除く際に、汚れがフィルタ面から付着物除去部材によって掻き落とされる過程において、特に、油脂分が平面的に開口されて点在する通気孔の孔内側に流れ込んでしまうなどによって油脂分を取り逃がし、油脂分を完全に取り除くことができない。また、通気孔を塞ぐように油脂分の油脂膜ができるおそれがあるなど、改善の余地が残されていた。   For this reason, in the range hood provided with the filter cleaning device previously proposed by the applicant, the filter member is driven and rotated after cooking to remove dirt such as oil and fat and dust from the filter surface. In the process of being scraped off from the filter surface by the adhering material removing member, especially when the oil and fat are opened in a plane and flow into the inside of the scattered air holes, the oil and fat are removed and the oil and fat are completely removed. It cannot be removed. In addition, there is still room for improvement, such as the possibility of forming an oil / fat oil film so as to close the vent hole.

そこで、本発明は、このような改善すべき課題に着目し、フィルタ面に沿わせて付着物除去部材を圧接させて油脂分や塵埃などの汚れを取り除く構成のフィルタ清掃装置を備えたレンジフードであって、汚れを取り逃がすことなく、確実に、かつ、効率的に取り除くフィルタ清掃が可能であること、汚染空気からの汚れの捕獲回収率（捕集回収率）の向上が期待できる汚染空気の通気構造とすること、などを目的とする。   Therefore, the present invention pays attention to such a problem to be improved, and a range hood provided with a filter cleaning device configured to remove dirt such as fats and oils and dust by pressing the deposit removing member along the filter surface. Therefore, it is possible to clean the filter reliably and efficiently without removing dirt, and to improve the capture and collection rate (collection and recovery rate) of dirt from contaminated air. The purpose is to provide a ventilation structure.

前記課題を解決するために、本発明では、調理中の汚染空気を吸い込み捕集する吸込み口から汚染空気を屋外に排気または室内に戻す吐出し口に至る排気風路に、フィルタ部材を回転可能に具備するフィルタ清掃装置を備え、該フィルタ清掃装置は、円盤形状に形成されている前記フィルタ部材を駆動回転させる駆動手段と、前記フィルタ部材のフィルタ面に沿って圧接させて付着物を取り除く付着物除去手段とを備えているレンジフードであって、
前記フィルタ部材は、回転中心部を中心とする回転円周線上に沿わせて前記汚染空気の通気部を断続的または連続的に備えてなり、前記通気部は、前記回転円周線またはその接線と略平行に切り込まれる２本の切込み縁の間に、前記フィルタ部材のフィルタ面から凸状に設けられる空気衝突面部と、該空気衝突面部と２本の切込み縁との間に設けられる通気孔とから形成され、
前記付着物除去手段は、前記フィルタ部材の回転時に、前記フィルタ面と前記空気衝突面部とからなる凸凹面に沿わせるように圧接させる付着物除去部材を備えていることを特徴とする。 In order to solve the above-mentioned problem, in the present invention, the filter member can be rotated to an exhaust air passage that leads from a suction port that sucks and collects contaminated air during cooking to a discharge port that exhausts the contaminated air outdoors or returns it indoors. The filter cleaning device includes a driving means for driving and rotating the filter member formed in a disk shape, and a pressure member along the filter surface of the filter member to remove attached matter. A range hood comprising kimono removing means,
The filter member is provided with a ventilation portion of the contaminated air intermittently or continuously along a rotation circumferential line centering on a rotation center portion, and the ventilation portion is the rotation circumference line or a tangent line thereof. And an air collision surface portion provided in a convex shape from the filter surface of the filter member, and a passage provided between the air collision surface portion and the two cutting edges. Formed from pores,
The adhering matter removing means includes an adhering matter removing member that press-contacts along the uneven surface formed by the filter surface and the air collision surface portion when the filter member rotates.

ここで、前記空気衝突面部は、前記排気風路の排気下流側に向けて凸状に形成され、前記付着物除去手段は、前記付着物除去部材を前記前記フィルタ部材に対して排気上流側から圧接させる位置に配設されていること、また、前記空気衝突面部の凸状幅は、前記フィルタ部材の回転中心部を中心とする回転円周線またはその接線と略平行に切り込まれる２本の切込み縁の切込み間隔よりも幅狭に形成されていること、などの構成を採用することが好適なものとなる。   Here, the air collision surface portion is formed in a convex shape toward the exhaust downstream side of the exhaust air passage, and the deposit removal means moves the deposit removal member from the exhaust upstream side with respect to the filter member. It is arranged at the position to be pressed, and the convex width of the air collision surface portion is a rotation circumferential line centering on the rotation center portion of the filter member or two that are cut substantially parallel to the tangent line. It is preferable to adopt a configuration such as being narrower than the cut interval of the cut edges.

また、前記通気部は、前記フィルタ部材の回転中心部を中心とする複数の各回転円周線上に沿わせてそれぞれ備えられ、前記付着物除去部材は、前記複数の各回転円周線と交差する方向に配設されて、前記フィルタ部材の回転時に、前記凸凹面に合わせて弾性変形するように形成されていることが好適なものとなる。
前記フィルタ部材の半径方向の凸凹面に沿って圧接される前記圧接縁辺部を弾性変形させるための構造形態としては、例えば、所望の押圧力によって圧接縁辺部をフィルタ面に圧接させた状態で、凸凹面に合わせて凸凹状に弾性変形する程度の軟らかさを有する不燃性ゴム材などを用いて、付着物除去部材の圧接縁辺部側のみを形成、または、付着物除去部材全体を形成する。また、適度の弾性を有する不燃性ゴム材などを用いて形成された付着物除去部材の圧接縁辺部に、所望の切込み深さで長さ方向に細かな間隔にて切目を入れることで、切れ目によって長さ方向に分離された多数の細部片を備えて、例えば、凸凹面のうち、凸部面に圧接される細部片部分では凸部面の凸形状や高さに合わせて大きく弾性変形するようにするなどの構造形態を挙げることができる。 Further, the ventilation portion is provided along each of the plurality of rotation circumferential lines centering on the rotation center portion of the filter member, and the deposit removing member intersects each of the plurality of rotation circumferential lines. Preferably, the filter member is formed so as to be elastically deformed in accordance with the uneven surface when the filter member is rotated.
As a structural form for elastically deforming the press contact edge that is pressed along the radial uneven surface of the filter member, for example, in a state where the press contact edge is pressed against the filter surface by a desired pressing force, Only the pressure contact edge side of the deposit removing member or the entire deposit removing member is formed by using a non-combustible rubber material or the like that is soft enough to be elastically deformed into a bumpy shape in accordance with the bumpy surface. In addition, the cut edge can be cut at fine intervals in the length direction at the desired depth of cut on the pressure contact edge of the deposit removing member formed using a non-combustible rubber material having appropriate elasticity. For example, among the convex and concave surfaces, the detail piece portion pressed against the convex surface greatly elastically deforms according to the convex shape and height of the convex surface. Examples of the structure are as follows.

また、他の構造形態としては、前記凸凹面に沿って圧接される前記圧接縁辺部側を、例えば、前記空気衝突面部の凸状幅などに合わせて長手方向に独立させたブロック状に分断（分割）し、コイル状のバネ材などを用いて分断された各分断部をそれぞれ支持させて、凸部に圧接される分断部部分では凸部の凸状高さに合わせて凹む（後退する）ように形成するなどの構造形態を挙げることができる。   Moreover, as another structural form, the said pressure contact edge part side press-contacted along the said uneven surface is divided | segmented into the block shape which made it independent in the longitudinal direction according to the convex width etc. of the said air collision surface part ( And split each part using a coiled spring material, etc., and dent (retreat) in accordance with the convex height of the convex part at the part that is pressed against the convex part. Examples of the structure form are as follows.

また、前記通気部は、前記フィルタ部材の回転中心部を中心とする複数の各回転円周線上に沿わせてそれぞれ備えられ、前記付着物除去部材は、前記複数の各回転円周線と交差する方向に配設されるとともに、前記フィルタ部材の回転時に、前記凸凹面に沿わせるように圧接させる圧接縁辺部が、前記各回転円周線と交差する位置に凸部または凹部を備え、交差しない位置に凹部または凸部を備えていることを特徴とする。この場合、前記凸部および前記凹部の一方または双方が、前記フィルタ部材の回転時に、前記凸凹面に合わせて弾性変形するように形成されていることが好適であり、また、前記凸部と前記凹部との境目に切目が設けて、両者を切り離した形態とすることが好適なものとなる。
また、前記フィルタ部材に、親水性または撥水性の表面処理が施されていることが好適なものとなる。 Further, the ventilation portion is provided along each of the plurality of rotation circumferential lines centering on the rotation center portion of the filter member, and the deposit removing member intersects each of the plurality of rotation circumferential lines. The pressure contact edge portion that is disposed so as to be in contact with the uneven surface when the filter member is rotated includes a convex portion or a concave portion at a position intersecting with each of the rotation circumferential lines. It is characterized by having a recess or a protrusion at a position where it is not. In this case, it is preferable that one or both of the convex portion and the concave portion are formed so as to be elastically deformed according to the concave and convex surface when the filter member is rotated. It is preferable that a cut is provided at the boundary between the recess and the both are separated.
Further, it is preferable that the filter member is subjected to a hydrophilic or water-repellent surface treatment.

このような構成によれば、汚染空気中から分離回収されてフィルタ部材に付着している油脂分や塵埃などの汚れ（付着物）は、駆動回転するフィルタ部材のフィルタ面と通気部の空気衝突面部との段差からなる凸凹面に沿わせて圧接される付着物除去手段の付着物除去部材によって掻き落とされるようにしてフィルタ面および通気部の空気衝突面部から取り除かれる。
このとき、フィルタ面に圧接する付着物除去部材の圧接縁辺部は、フィルタ面と空気衝突面部との凸凹面に合わせて弾性変形し、フィルタ面および空気衝突面部に対するそれぞれの圧接状態が保たれてフィルタ面および空気衝突面部に付着している汚れを取り除くフィルタ部材の清掃が行われる。 According to such a configuration, dirt (fouling matter) such as oil and fat separated and collected from contaminated air and adhering to the filter member is caused by an air collision between the filter surface of the rotating filter member and the ventilation portion. It is removed from the air collision surface portion of the filter surface and the ventilation portion so as to be scraped off by the deposit removing member of the deposit removing means that is press-contacted along the uneven surface having a step with the surface portion.
At this time, the pressure contact edge portion of the deposit removing member that is in pressure contact with the filter surface is elastically deformed according to the uneven surface of the filter surface and the air collision surface portion, and the pressure contact state with respect to the filter surface and the air collision surface portion is maintained. Cleaning of the filter member that removes dirt adhering to the filter surface and the air collision surface portion is performed.

また、付着物除去部材の圧接縁辺部が、フィルタ面と通気部の空気衝突面部とからなる凸凹面に合わせた凸部と凹部とを備えている。詳しくは、通気部が形成されるフィルタ部材の回転中心部を中心とする複数の各回転円周線と交差する位置に凸部または凹部を備え、交差しない位置には凹部または凸部を備えた凸凹形状に形成されている構成を採用することで、フィルタ部材の回転時に、フィルタ面および空気衝突面部に対する圧接縁辺部の圧接状態がより確実に保たれて、フィルタ面および空気衝突面部に付着している汚れを確実に、かつ、効率的に取り除くフィルタ部材の清掃が行われる。
例えば、空気衝突面部が、排気風路の排気上流側に面するフィルタ面（付着物除去手段が配設されるフィルタ面）から排気下流側に向けて凸状に形成されている。すなわち、排気風路の排気上流側に面するフィルタ面側から見たとき、該フィルタ面から排気下流側に向けて凹状に形成された空気衝突面部とフィルタ面からなる凸凹面である場合には、この凸凹面に沿うように圧接される付着物除去部材の圧接縁辺部を、凹状の空気衝突面部に圧接させる位置（前記各回転円周線と交差する位置）に凸部を備え、フィルタ面に圧接させる位置（前記各回転円周線と交差しない位置）に凹部を備えた凸凹縁構造とする。
これにより、フィルタ部材の回転時に、圧接縁辺部の凸部が凹状の空気衝突面部に、凹部がフィルタ面に対してそれぞれ適切な状態で圧接されることで、フィルタ面および空気衝突面部から汚れを取り除くフィルタ部材の清掃が良好に行われる。 Moreover, the press-contacting edge part of the deposit removing member includes a convex part and a concave part that match the concave and convex surface formed by the filter surface and the air collision surface part of the ventilation part. Specifically, a convex portion or a concave portion is provided at a position that intersects each of the plurality of rotation circumferential lines centering on the rotation center portion of the filter member in which the ventilation portion is formed, and a concave portion or a convex portion is provided at a position that does not intersect By adopting a configuration that is formed in a concavo-convex shape, when the filter member rotates, the pressure contact state of the pressure contact edge with respect to the filter surface and the air collision surface portion is more reliably maintained, and adheres to the filter surface and the air collision surface portion. Cleaning of the filter member that reliably and efficiently removes dirt is performed.
For example, the air collision surface portion is formed in a convex shape from the filter surface facing the exhaust upstream side of the exhaust air passage (the filter surface on which the deposit removing means is disposed) toward the exhaust downstream side. In other words, when viewed from the filter surface side facing the exhaust upstream side of the exhaust air passage, the air collision surface portion formed in a concave shape from the filter surface toward the exhaust downstream side, and a convex / concave surface consisting of the filter surface The filter surface is provided with a convex portion at a position where the pressure contact edge portion of the deposit removing member that is pressure-contacted along the concave and convex surface is pressed against the concave air collision surface portion (a position intersecting with each of the rotation circumferential lines). It is set as the convex-concave edge structure provided with the recessed part in the position (position which does not cross | intersect said each rotation circumference line) to press-contact to.
Thus, when the filter member is rotated, the convex portion of the pressure contact edge is pressed against the concave air collision surface portion and the concave portion is pressed against the filter surface in an appropriate state, so that the filter surface and the air collision surface portion are contaminated. The filter member to be removed is cleaned well.

また、前記した圧接縁辺部の凸部が、フィルタ部材の回転円周線に沿う凸凹面に合わせて弾性変形するように形成され、通気部が回転円周線上に断続的に配置されている場合、凸部は、弾性変形のもとで回転円周線上に存在する通気部の空気衝突面部とフィルタ面に対する圧接状態が確実に保たれ、フィルタ面および空気衝突面部から汚れを取り除くフィルタ部材の清掃が行われる。   Further, when the convex portion of the press contact edge portion is formed so as to be elastically deformed according to the concave and convex surface along the rotation circumferential line of the filter member, and the ventilation portion is intermittently disposed on the rotation circumferential line. The convex portion is maintained in pressure contact with the air collision surface portion and the filter surface of the ventilation portion existing on the rotation circumference under elastic deformation, and the filter member is cleaned to remove dirt from the filter surface and the air collision surface portion. Is done.

また、通気部の空気衝突面部を、前記のように排気風路の排気下流側に向けた凸状の構成を採用した場合、空気衝突面部とフィルタ部材の回転円周線またはその接線と略平行に切り込まれる２本の切込み縁との間に汚染空気が通過する通気孔を設けた構造を採用することで、調理中の汚染空気が排気風路の排気上流側からフィルタ部材を通過して排気風路の排気下流側へ通り抜けるとき、汚染空気は空気衝突面部へ衝突（接触）しながら、側方（汚染空気が通過する方向に対して直交するフィルタ面方向）に向けて開口する通気孔方向へ向きを大きく変えながら排気下流側に抜ける。
これにより、汚染空気中の油脂分や塵埃などの汚れは、空気衝突面部への衝突によって分離回収される。つまり、汚染空気がフィルタ部材を通過するときの空気衝突面部への衝突によるフィルタ部材への付着によって行われる汚れの回収原理を最大限に作用させて、汚染空気から汚れを分離回収することができる。 In addition, when a convex configuration in which the air collision surface portion of the ventilation portion is directed toward the exhaust downstream side of the exhaust air passage as described above is employed, the air collision surface portion and the rotation circumferential line of the filter member or a tangent line thereof are substantially parallel. By adopting a structure in which a vent hole through which contaminated air passes is provided between the two cutting edges cut into the air, the contaminated air during cooking passes through the filter member from the exhaust upstream side of the exhaust air passage. When passing through the exhaust air downstream side of the exhaust air passage, the contaminated air collides (contacts) with the air collision surface portion, and opens to the side (filter surface direction perpendicular to the direction in which the contaminated air passes). Moves to the exhaust downstream side while greatly changing the direction.
Thereby, dirt such as oil and fat and dust in the contaminated air is separated and recovered by collision with the air collision surface portion. That is, the dirt can be separated and collected from the contaminated air by maximizing the principle of collecting the dirt performed by adhering to the filter member due to the collision with the air collision surface when the contaminated air passes through the filter member. .

一方、前記した付着物除去部材の圧接縁辺部の凸凹縁構造に対し、空気衝突面部が、排気風路の排気下流側に面するフィルタ面から排気上流側に向けて凸状に形成されている。すなわち、排気風路の排気上流側に面するフィルタ面（付着物除去手段が配設されるフィルタ面）側から見たときに、該フィルタ面から排気上流側に向けて凸状に形成された空気衝突面部とフィルタ面からなる凸凹面である場合には、この凸凹面に沿うように圧接される付着物除去部材の圧接縁辺部を、凸状の空気衝突面部に圧接させる位置（前記各回転円周線と交差する位置）に凹部を備え、フィルタ面に圧接させる位置（前記各回転円周線と交差しない位置）に凸部を備えた凸凹縁構造とする。
これにより、フィルタ部材の回転時に、圧接縁辺部の凹部が凸状の空気衝突面部に、凸部がフィルタ面に対してそれぞれ適切な状態で圧接されることで、フィルタ面および空気衝突面部から汚れを取り除くフィルタ部材の清掃が良好に行われる。
この場合、圧接縁辺部の凹部と凸部が弾性変形可能に形成され、なおかつ、凹部と凸部との境目に両者を切り離す切目が形成されている構成を採用することで、例えば、通気部が回転円周線上に断続的に配置されている場合、凸部は弾性変形した状態でフィルタ部材のフィルタ面に圧接されるとともに、凹部は回転円周線上に存在するフィルタ面に圧接した状態で付着除去部材がフィルタ除去装置に設置される。そして、フィルタ部材の回転時に、凹部の圧接が回転円周線上のフィルタ面から凸状の空気衝突面部へと移るときに、凹部は弾性変形することで凸状の通気衝突面部に対する圧接状態が保たれる。このとき、凸部は凹部との境界に設けられている切目によって凹部と切り離されていることで、凹部の弾性変形に大きく影響されることなく、フィルタ面に対する圧接状態が保たれる。これにより、フィルタ面および空気衝突面部から適確に汚れを取り除くフィルタ部材の清掃が行われる。 On the other hand, the air collision surface portion is formed in a convex shape from the filter surface facing the exhaust downstream side of the exhaust air passage toward the exhaust upstream side with respect to the uneven edge structure of the pressure contact edge portion of the deposit removing member. . That is, when viewed from the filter surface facing the exhaust upstream side of the exhaust air passage (the filter surface on which the deposit removing means is disposed), it is formed in a convex shape from the filter surface toward the exhaust upstream side. In the case of a concave / convex surface consisting of an air collision surface portion and a filter surface, the position where the pressure contact edge portion of the deposit removing member that is press-contacted along the concave / convex surface is pressed against the convex air collision surface portion (the rotations described above) A concave-convex edge structure is provided in which a concave portion is provided at a position that intersects the circumferential line and a convex portion is provided at a position that is pressed against the filter surface (a position that does not intersect each of the rotating circumferential lines).
Accordingly, when the filter member is rotated, the concave portion of the pressure contact edge is pressed against the convex air collision surface portion and the convex portion is pressed against the filter surface in an appropriate state, so that the filter surface and the air collision surface portion are contaminated. The filter member that removes the water is satisfactorily cleaned.
In this case, by adopting a configuration in which the concave portion and the convex portion of the pressure contact edge portion are formed so as to be elastically deformable, and a cut is formed at the boundary between the concave portion and the convex portion, for example, the ventilation portion is provided. When it is intermittently arranged on the rotating circumference, the convex part is pressed against the filter surface of the filter member in an elastically deformed state, and the concave part adheres to the filter surface existing on the rotating circumferential line. A removal member is installed in the filter removal device. During the rotation of the filter member, when the pressure contact of the concave portion moves from the filter surface on the rotation circumference to the convex air collision surface portion, the concave portion is elastically deformed so that the pressure contact state with respect to the convex ventilation collision surface portion is maintained. Be drunk. At this time, since the convex portion is separated from the concave portion by the cut provided at the boundary with the concave portion, the pressure contact state with respect to the filter surface is maintained without being greatly influenced by the elastic deformation of the concave portion. Thereby, cleaning of the filter member which removes dirt from the filter surface and the air collision surface portion accurately is performed.

そして、調理中に汚染空気が通過する通気孔は、汚れが付着するフィルタ面および空気衝突面部に対して直交する方向を向いて開口されていることで、付着物除去部材によってフィルタ面および空気衝突面部から汚れを掻き落す過程において、汚れを通気孔の孔縁内側に取り逃がすことなく、しかも、通気孔を油脂膜の発生によって塞ぐことなく、フィルタ部材の清掃を遂行させることができる。   The vent hole through which the contaminated air passes during cooking is opened in a direction perpendicular to the filter surface and the air collision surface portion to which the dirt adheres, so that the filter surface and the air collision are caused by the deposit removing member. In the process of scraping off the dirt from the surface portion, the filter member can be cleaned without removing the dirt to the inside of the hole edge of the vent hole and without blocking the vent hole by the generation of the oil film.

また、フィルタ部材の回転円周線またはその接線と略平行に切り込まれる２本の切込み縁の切込み間隔よりも空気衝突面部の凸状幅が幅狭に形成されている構成の通気部構造を採用することで、付着物除去部材によるフィルタ面および空気衝突面部から汚れの掻き落し過程において、通気孔を塞ぐ油脂膜の発生をより確実に防ぐことができる。
つまり、２本の切込み縁（縁延長線上）よりも内側に位置して存在する空気衝突面部の凸状幅縁と２本の切込み縁との間に形成される通気孔は、１つの平面（フィルタ面と面一の平面）ではなく、この１つの平面と空気衝突面部の凸方向の垂直平面との２つの平面により断面視で略Ｌ字開口形状になっている。これにより、１つの平面による通気孔の場合と比較して油脂膜は安定状態になり難いために、通気孔を塞ぐ油脂膜の発生を抑えることができる。 In addition, a vent structure having a configuration in which the convex width of the air collision surface portion is formed narrower than the incision interval between two incision edges that are substantially parallel to the rotation circumferential line of the filter member or its tangent line. By adopting, in the process of scraping off dirt from the filter surface and the air collision surface portion by the deposit removing member, it is possible to more reliably prevent the generation of an oil film that closes the vent hole.
That is, the air hole formed between the convex width edge of the air collision surface portion existing on the inner side of the two cut edges (on the edge extension line) and the two cut edges has one plane ( Instead of a flat surface that is flush with the filter surface, a substantially L-shaped opening shape is obtained in a cross-sectional view by two planes, that is, this one plane and a vertical plane in the convex direction of the air collision surface portion. As a result, the oil / fat film is less likely to be in a stable state as compared with the case of the vent hole formed by one plane, and therefore, the generation of the oil / fat film that blocks the vent hole can be suppressed.

また、フィルタ部材に親水性または撥水性の表面処理が施されていることで、汚れなどの溜まりを防ぎ、汚れが落ち易くなることから、付着物除去部材によって速やかに、かつ、効率的に汚れを取り除くことができる。   In addition, since the filter member is subjected to a hydrophilic or water-repellent surface treatment, accumulation of dirt and the like can be prevented and dirt can be easily removed. Can be removed.

本発明のフィルタ清掃装置を備えたレンジフードによれば、駆動回転するフィルタ部材から油脂分や塵埃などの汚れを掻き落すように取り除く過程において、汚れを通気孔の孔縁内側に取り逃がすことなく、しかも、油脂膜の発生によって通気孔を塞ぐことなく、駆動回転するフィルタ部材の汚れが付着しているフィルタ面および空気衝突面部から汚れを取り除くフィルタ部材の清掃を遂行させることができる。
また、フィルタ面および通気部の空気衝突面部とからなる凸凹面に付着している汚れを、弾性変形または凸部と凹部とを備えている付着物除去部材の圧接縁辺部によって確実に、かつ、効率的に取り除くことができる。
これにより、清掃機能を低下させることなく長期使用が可能となることから、使用者に対するメンテナンスなどの手間を軽減させることができる。 According to the range hood provided with the filter cleaning device of the present invention, in the process of removing dirt such as oil and fat and dust from the drive rotating filter member so as to scrape off, without removing dirt inside the hole edge of the vent hole, Moreover, it is possible to perform cleaning of the filter member that removes dirt from the filter surface on which the filter member that rotates and rotates and the air collision surface portion do not block the vent hole due to the generation of the oil film.
In addition, the dirt adhering to the uneven surface formed by the filter surface and the air collision surface portion of the ventilation portion can be reliably deformed by the elastic contact or the pressure contact edge portion of the attached matter removing member having the convex portion and the concave portion, and Can be removed efficiently.
Thereby, since it becomes possible to use for a long time without deteriorating the cleaning function, it is possible to reduce the troubles such as maintenance for the user.

また、本発明のフィルタ清掃装置を備えたレンジフードによれば、調理中の汚染空気が排気風路の排気上流側からフィルタ部材を通過して排気下流側へ通り抜けるとき、汚染空気は通気部の空気衝突面部に衝突（接触）しながら、側方（フィルタ面方向）に向けて開口する通気孔方向へ向きを大きく変えながら排気下流側に抜ける。
これにより、排気空気の衝突による油脂分や塵埃などの汚れの分離回収率（捕獲または捕集回収率）を向上させることができる。 Further, according to the range hood provided with the filter cleaning device of the present invention, when contaminated air during cooking passes through the filter member from the exhaust upstream side of the exhaust air passage and passes through the exhaust downstream side, the contaminated air flows through the ventilation portion. While colliding with (contacting with) the air collision surface portion, the air exits to the exhaust downstream side while greatly changing the direction in the direction of the vent hole that opens toward the side (filter surface direction).
Thereby, the separation / recovery rate (capture or collection / recovery rate) of dirt such as oil and fat or dust due to collision of exhaust air can be improved.

図１は、本実施形態に係るレンジフードを示す縦断面図であり、図２および図３は、要部を拡大して示す断面図である。
なお、レンジフードとしては、捕獲空間が浅く形成されている薄型（平型）タイプと、捕獲空間が深く形成されている深型タイプとの２種類に大別されるが、本実施形態では、図１に示すように、薄型タイプのレンジフードを挙げて説明する。また、薄型タイプのレンジフードでは、フード部の上に送風機が縦置きに設置される縦置きタイプと、送風機が横置きに設置される横置きタイプとがあるが、本実施形態では、図１に示すように、横置きタイプのレンジフードを挙げて説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a longitudinal sectional view showing a range hood according to this embodiment, and FIGS. 2 and 3 are sectional views showing an enlarged main part.
The range hood is roughly classified into two types, a thin type (flat type) in which the capture space is formed shallow and a deep type in which the capture space is formed deeply. As shown in FIG. 1, a thin type range hood will be described. In addition, in the thin type range hood, there are a vertical installation type in which the blower is installed vertically on the hood portion and a horizontal installation type in which the blower is installed horizontally. In the present embodiment, FIG. As shown in Fig. 4, a horizontal type range hood will be described.

≪レンジフードの説明≫
レンジフードＡは、周知のように、調理中に発生する油煙、湯煙（水蒸気）、熱気、そして廃ガスなどの汚染空気Ｇを吸込み捕集し、図示省略の排気ダクトを通して屋外に排気、または、排気風路１０の排気下流側に配置されている図示省略の脱臭フィルタなどの各種フィルタを具備する濾過装置により分離除去して清浄化した後に、クリーンな空気として室内に戻すように構成されている。
このレンジフードＡは、図１に示すように、薄型（平型）で下向きに開口する捕獲空間Ｍを有するフード部１と、このフード部１の上に設置される送風機２と、捕獲空間Ｍの下向き開口部に取り付けられる整流板３とを備えて構成されている。 ≪Description of range hood≫
As is well known, the range hood A sucks and collects polluted air G such as oil smoke, steam (steam), hot air, and waste gas generated during cooking, and exhausts it outdoors through an exhaust duct (not shown), or It is configured to be separated and removed by a filtering device including various filters such as a deodorizing filter (not shown) disposed on the exhaust downstream side of the exhaust air passage 10 and then returned to the room as clean air. .
As shown in FIG. 1, the range hood A is a thin (flat) hood portion 1 having a capture space M that opens downward, a blower 2 installed on the hood portion 1, and a capture space M. And a current plate 3 attached to the downward opening.

このように、フード部１の上に送風機２を設置している薄型のレンジフードＡは、周知の設置構造によってキッチンに取り付け設置される。例えば、図１に示すように、送風機２の後記する送風機ボックス２ａがＬ形の吊り金具４を用いたネジ止めなどによってキッチン壁Ｋに取り付けられて、図示省略の加熱調理器の略真上に位置して設置される。   In this way, the thin range hood A in which the blower 2 is installed on the hood portion 1 is installed and installed in the kitchen by a known installation structure. For example, as shown in FIG. 1, a blower box 2a, which will be described later of the blower 2, is attached to a kitchen wall K by screwing or the like using an L-shaped hanging bracket 4, and is directly above a heating cooker (not shown). Located in place.

フード部１は、下向き開口する扁平箱型に形成され、開口内側にオイルパネル５が取り付けられることで、所望の深さを有する下向き凹部形状の捕獲空間Ｍが開口内側に備えられるようになっている。
オイルパネル５は、周辺縁部を残して上方に膨出させた凹みを備え、周辺縁部がフード部１の開口内側にスポット溶着やネジ止めなどの止着手段を用いて取り付けられるように形成されている。
これにより、フード部１の厚さ（高さ）内に収まる深さで、キッチン壁面Ｋに突き合わせされるフード部１の背面側（図１紙面右側）からキッチン側（図１紙面左側）に位置するフード部１の前面側に至るにしたがって深さが徐々に深くなる捕獲空間Ｍが、フード部１の開口内側に形成される。 The hood portion 1 is formed in a flat box shape that opens downward, and the oil panel 5 is attached to the inside of the opening, so that a downward recessed trapping space M having a desired depth is provided inside the opening. Yes.
The oil panel 5 is provided with a dent bulging upward leaving the peripheral edge, and the peripheral edge is formed to be attached to the inner side of the opening of the hood portion 1 by using a fixing means such as spot welding or screwing. Has been.
Thus, the depth is within the thickness (height) of the hood part 1 and is located on the kitchen side (left side of FIG. 1 paper) from the back side (right side of FIG. 1 paper) of the hood part 1 butted against the kitchen wall K. A capture space M whose depth gradually increases toward the front side of the hood portion 1 is formed inside the opening of the hood portion 1.

また、フード部１は、送風機２が設置される背面側に位置する天板１ａの一部に、捕獲空間Ｍに連通させた送風機設置部６を天板１ａよりも高く備えて、後記のフィルタ清掃装置Ｂを構成する駆動手段１６のモータ１６ａを内設し得る空間を、捕獲空間Ｍと送風機ボックス２ａとの間に確保するようにしている。つまり、図１に示すように、捕獲空間Ｍに連通させてオイルパネル５に取り付けられるフィルタ清掃装置Ｂをフード部１内に組み込み内設し得るようにしている。   Further, the hood unit 1 is provided with a blower installation unit 6 communicated with the capture space M at a part of the top plate 1a located on the back side where the blower 2 is installed, higher than the top plate 1a. A space in which the motor 16a of the driving means 16 constituting the cleaning device B can be installed is secured between the capture space M and the blower box 2a. That is, as shown in FIG. 1, a filter cleaning device B that communicates with the capture space M and is attached to the oil panel 5 can be incorporated in the hood portion 1.

送風機２は、図１に示すように、下面を開口させた略四角形状の箱型に形成されている送風機ボックス２ａの内部に、ファンケーシング２ｂを横置き状態で内設してなる。
ファンケーシング２ｂは、排気ダクトが接続される吐出し口７を有するボリュート形状に形成され、ファンモータ２ｃに軸支されて同軸上に収容される排気ファン２ｄを収容している。 As shown in FIG. 1, the blower 2 has a fan casing 2 b installed in a horizontally placed state inside a blower box 2 a formed in a substantially square box shape with an open bottom surface.
The fan casing 2b is formed in a volute shape having a discharge port 7 to which an exhaust duct is connected, and accommodates an exhaust fan 2d that is pivotally supported by the fan motor 2c and accommodated coaxially.

整流板３は、捕獲空間Ｍの下向き開口部の開口形状よりも小さい平板形状に形成されて、捕獲空間Ｍに開閉・係脱自在に取り付けられる。これにより、図１に示すように、整流板３の周囲各辺縁部と捕獲空間Ｍの開口周縁部との間に汚染空気Ｇの吸込み口８が確保されて、汚染空気Ｇが整流板３に沿って吸込み口８から捕獲空間Ｍ内に勢い良く吸気（捕集）されるようになっている。   The rectifying plate 3 is formed in a flat plate shape that is smaller than the opening shape of the downward opening of the capture space M, and is attached to the capture space M so that it can be opened / closed / detached. As a result, as shown in FIG. 1, the intake port 8 for the contaminated air G is secured between the peripheral edges of the current plate 3 and the opening peripheral edge of the capture space M, so that the contaminated air G flows into the current plate 3. The air is sucked (collected) vigorously into the capture space M from the suction port 8.

また、レンジフードＡは、図１に示すように、フード部１の調理者側である前面部にスイッチ操作部９を備えている。
このスイッチ操作部９は、送風機２の運転（強・中・弱）開始、停止の切り替え、そしてフィルタ清掃装置Ｂの運転開始、停止の切り替えなどの操作を行うタッチやプッシュタイプからなるスイッチ類（図示省略）を備えている。 Moreover, the range hood A is provided with the switch operation part 9 in the front part which is the cooker side of the food | hood part 1, as shown in FIG.
The switch operation unit 9 is a touch or push type switch (such as start / stop switching of the operation (strong / medium / weak) of the blower 2) and switch operation (start / stop switching of the filter cleaning device B). (Not shown).

そして、このように構成されているレンジフードＡの吸込み口８から吐出し口７に至る排気風路１０に、フィルタ部材１１を回転可能に具備するフィルタ清掃装置Ｂを備えている。
これにより、吸込み口８から捕獲空間Ｍに吸い込み捕獲された汚染空気Ｇが排気風路１０を通り吐出し口７側へと吸引されて流れるとき、汚染空気中から分離回収されてフィルタ部材１１に付着した油脂分や塵埃などの汚れ（付着物）を、フィルタ部材１１を駆動回転させることでフィルタ部材１１から掻き落とすように取り除くことができるように構成している。 And the filter cleaning apparatus B which comprises the filter member 11 rotatably is provided in the exhaust air path 10 from the suction inlet 8 of the range hood A comprised in this way to the discharge outlet 7. As shown in FIG.
As a result, when the contaminated air G sucked and captured from the suction port 8 into the capture space M is discharged through the exhaust air passage 10 and flows into the suction port 7 side, it is separated and recovered from the contaminated air and is collected in the filter member 11. It is configured such that dirt (attachment) such as attached oil and fat or dust can be removed by scraping the filter member 11 by driving and rotating the filter member 11.

≪フィルタ部材の説明≫
図３は、フィルタ部材を示す斜視図および構成説明図であり、図４は、通気部の一部を拡大して示す断面図である。ここでは、図１および図２を適宜参照しながら説明する。
なお、図４において、紙面上側が排気風路１０の排気下流側となり、紙面下側が排気風路１０の排気上流側となる。
フィルタ部材１１は、所望の金属板（亜鉛めっき鋼板、耐食アルミニウム板、ステンレス鋼板など）を用いて適宜の外径寸法を有する円盤形状に形成されている。
このフィルタ部材１１は、図３に示すように、回転中心部Ｐを中心として半径が異なる複数の各回転円周線Ｙ上に沿わせて排気空気Ｇの通気部１２をそれぞれ備えている。 ≪Description of filter member≫
FIG. 3 is a perspective view and a configuration explanatory view showing the filter member, and FIG. 4 is an enlarged sectional view showing a part of the ventilation portion. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
In FIG. 4, the upper side of the paper is the exhaust downstream side of the exhaust air passage 10, and the lower side of the paper is the exhaust upstream side of the exhaust air passage 10.
The filter member 11 is formed in a disk shape having an appropriate outer diameter using a desired metal plate (galvanized steel plate, corrosion-resistant aluminum plate, stainless steel plate, etc.).
As shown in FIG. 3, the filter member 11 includes exhaust air G ventilation portions 12 along a plurality of rotation circumferential lines Y having different radii around the rotation center portion P.

≪通気部の説明≫
通気部１２は、切込み加工と曲げ加工などによって、各回転円周線Ｙ上に沿わせて断続的に配置されている。
この通気部１２は、図３の（ｂ）および図４に示すように、回転円周線Ｙと略平行に切り込まれる２本の切込み縁１３の間に、排気風路１０の排気上流側に面するフィルタ部材１１のフィルタ面（以後、「上流側フィルタ面」と称する）１１ａから排気下流側に向けて凸状に設けられる空気衝突面部１２ａと、この空気衝突面部１２ａと２本の切込み縁１３との間に設けられる通気孔１２ｂとから形成されている。 ≪Explanation of ventilation part≫
The ventilation part 12 is intermittently disposed along each rotation circumferential line Y by cutting and bending.
As shown in FIG. 3B and FIG. 4, the ventilation portion 12 is provided between the two cut edges 13 cut substantially parallel to the rotation circumferential line Y and on the exhaust upstream side of the exhaust air passage 10. The air collision surface portion 12a provided in a convex shape from the filter surface (hereinafter referred to as "upstream filter surface") 11a of the filter member 11 facing the exhaust toward the exhaust downstream side, and the air collision surface portion 12a and two cuts The air hole 12b is provided between the edge 13 and the air hole 12b.

空気衝突面部１２ａは、調理中の汚染空気Ｇがフィルタ部材１１を通過するとき、汚染空気Ｇを衝突（接触）させて、油脂分や塵埃などの汚れを汚染空気Ｇから捕獲回収（分離回収）することを促進させる役目と、排気風路１０の排気下流側に面するフィルタ部材１１のフィルタ面（以後、「下流側フィルタ面」と称する）１１ｂの面方向に向けて通気孔１２ｂを開口する役目とを成すものである。
この空気衝突面部１２ａは、図４および後記の図５に示すように、上流側フィルタ面１１ａから排気風路１０の排気下流側に向けた略アーチ形状（略弓形形状）の凸状（上流側フィルタ面１１a側から見て凹状）に曲げ加工されている。
そして、空気衝突面部１２ａは、図４の（ｂ）に示すように、空気衝突面部１２ａの凸状幅Ｌ１は、２本の切込み縁１３の切込み間隔Ｌ２よりも幅狭に形成されている。
例えば、切込み間隔Ｌ２を４ｍｍとした場合、空気衝突面部１２ａの凸状幅Ｌ１を３ｍｍとして、空気衝突面部１２ａの凸状幅縁１４が、２本の切込み縁１３の縁延長線上よりも０．５ｍｍ内側に位置するように空気衝突面部１２ａの凸状幅Ｌ１が形成されている。
これにより、通気孔１２は、図４の（ｂ）および後記の図５に示すように、２本の切込み縁１３と空気衝突面部１２ａの凸状幅縁との間に断面視で略斜め開口形状または略Ｌ字開口形状にて形成される。 When the contaminated air G being cooked passes through the filter member 11, the air collision surface portion 12 a collides (contacts) the contaminated air G and captures and collects dirt such as oil and fat and dust from the contaminated air G (separate recovery). The vent 12b is opened toward the surface direction of the filter surface 11b (hereinafter referred to as "downstream filter surface") of the filter member 11 facing the exhaust downstream side of the exhaust air passage 10 and the role of promoting The role.
As shown in FIG. 4 and FIG. 5 to be described later, the air collision surface portion 12a has a substantially arch-shaped (substantially arcuate) convex shape (upstream side) from the upstream filter surface 11a toward the exhaust downstream side of the exhaust air passage 10. It is bent into a concave shape when viewed from the filter surface 11a side.
As shown in FIG. 4B, the air collision surface portion 12 a is formed so that the convex width L <b> 1 of the air collision surface portion 12 a is narrower than the cutting interval L <b> 2 of the two cutting edges 13.
For example, when the cut interval L2 is 4 mm, the convex width L1 of the air collision surface portion 12a is set to 3 mm, and the convex width edge 14 of the air collision surface portion 12a is 0. 0 than on the edge extension line of the two cut edges 13. A convex width L1 of the air collision surface portion 12a is formed so as to be located 5 mm inside.
Thereby, as shown in FIG. 4B and FIG. 5 to be described later, the vent hole 12 is opened substantially obliquely in cross section between the two cut edges 13 and the convex width edge of the air collision surface portion 12a. It is formed in a shape or a substantially L-shaped opening shape.

また、フィルタ部材１１は、親水性または撥水性の表面処理が施されている。これにより、汚れなどの溜まりを防ぎ、フィルタ清掃装置Ｂの後記する付着物除去手段１７の付着物除去部材１７ａによって、汚れが付着する上流側フィルタ面１１ａおよび空気衝突面部１２ａなどから汚れを速やかに、かつ、簡単に取り除くことができるようにしている。   The filter member 11 is subjected to a hydrophilic or water-repellent surface treatment. Accordingly, accumulation of dirt is prevented, and dirt is quickly removed from the upstream filter surface 11a and the air collision surface portion 12a to which dirt adheres by the deposit removing member 17a of the deposit removing means 17 described later of the filter cleaning device B. And it can be easily removed.

図５は、フィルタ部材を通過するときの排気空気の流れを示す説明図である。
なお、図５において、紙面上側が排気風路１０の排気下流側となり、紙面下側が排気風路１０の排気上流側となる。
このように、フィルタ部材１１の回転円周線Ｙ上に沿って備えられる汚染空気Ｇの通気部１２は、下流側フィルタ面１１ｂから排気風路１１の排気下流側に向けて凸状に設けられる空気衝突面部１２ａと、空気衝突面部１２ａと２本の切込み縁１３との間に設けられる通気孔１２ｂとから形成されている通気構造であることで、調理中にフード部１の捕獲空間Ｍに吸い込み捕集された汚染空気Ｇがフィルタ部材１１を通過して排気風路１０の排気下流側へ通り抜けるとき、図５に示すように、汚染空気Ｇは空気衝突面部１２ａへ衝突（接触）しながら、側方（汚染空気Ｇが通過する方向に対して直交する下流側フィルタ面１１ｂの面方向）に向けて開口する通気孔１２ｂ方向へ向きを大きく変えながら排気下流側に抜けることとなる。
これにより、汚染空気Ｇの衝突によって油脂分や塵埃などの汚れの分離回収率（捕獲または捕集回収率）を向上させることができる。 FIG. 5 is an explanatory diagram showing the flow of exhaust air when passing through the filter member.
In FIG. 5, the upper side of the paper is the exhaust downstream side of the exhaust air passage 10, and the lower side of the paper is the exhaust upstream side of the exhaust air passage 10.
Thus, the polluted air G ventilation portion 12 provided along the rotation circumferential line Y of the filter member 11 is provided in a convex shape from the downstream filter surface 11 b toward the exhaust downstream side of the exhaust air passage 11. It is a ventilation structure formed from the air collision surface portion 12a and the air hole 12b provided between the air collision surface portion 12a and the two cut edges 13, so that the capture space M of the hood portion 1 can be used during cooking. When the contaminated air G sucked and collected passes through the filter member 11 and passes downstream of the exhaust air passage 10, the contaminated air G collides (contacts) with the air collision surface portion 12a as shown in FIG. Then, the exhaust gas flows out to the exhaust downstream side while greatly changing the direction in the direction of the vent hole 12b opening toward the side (surface direction of the downstream filter surface 11b orthogonal to the direction in which the contaminated air G passes).
Thereby, the separation / recovery rate (capture or collection / recovery rate) of dirt such as oil and fat and dust due to the collision of the contaminated air G can be improved.

≪フィルタ清掃装置の説明≫
図６および図７は、本実施形態に係るフィルタ清掃装置を示す分解斜視図である。ここでは、図１および図２を適宜参照しながら説明する。
なお、図６および図７に示すフィルタケース１５の方向性において、紙面斜め下向き右側がレンジフードＡの前側（調理者側）となり、紙面斜め上向き左側がレンジフードＡの後側（キッチン壁Ｋ側）となり、紙面斜め上向き右側と斜め下向き左側がレンジフードＡの左右両側になる。 ≪Description of filter cleaning device≫

このフィルタ清掃装置Ｂは、図２、図６および図７に示すように、フィルタ部材１１を回転可能に支持収容するフィルタケース１５と、フィルタ部材１１を所定の回転角速度にて駆動回転させる駆動手段１６とフィルタ部材１１の上流側フィルタ面１１ａに沿わせて線状または面状に圧接させる付着物除去手段１７とを備えて構成されている。 The filter cleaning device B includes the filter member 11 so as to be rotatable, and in addition to use, the filter cleaning device B adheres to the upstream filter surface 11a of the filter member 11 and the air collision surface portion 12a of the ventilation portion 12 and accumulates oil and fat, dust, etc. The filter member 11 is cleaned by removing the dirt so as to be scraped off.
As shown in FIGS. 2, 6, and 7, the filter cleaning device B includes a filter case 15 that rotatably supports and accommodates the filter member 11, and a drive unit that drives and rotates the filter member 11 at a predetermined rotational angular velocity. 16 and adhering matter removing means 17 that press-contacts linearly or planarly along the upstream filter surface 11 a of the filter member 11.

≪フィルタケースの説明≫

Although not shown, the gear support member 28 is provided with a highly lubricious member made of a synthetic resin material or the like inside the grip portion 28a so that the second gear 32 can rotate with good slipperiness. It can be gripped.

≪駆動手段の説明≫
このように形成されている上下のケース部１５ａ，１５ｂの間に回転可能に支持収容されるフィルタ部材１１を駆動回転させる駆動手段１６は、モータ１６ａと、このモータ１６ａの動力をフィルタ部材１１に伝達する動力伝達機構１６ｂとを備えて構成されている。
モータ１６ａは、モータ支持台２９を介して上側ケース部１５ａ側に設置される。
モータ支持台２９は、略櫓形状に形成されており、窓孔２７の開口中心線上に位置させた上側ケース部１５ａのコーナー部外側（排気下流側）にネジ止め設置される。これにより、モータ１６ａの出力軸３０を、窓孔２７から上下のケース部１５ａ，１５ｂの間に下向き突出状に内在させるようにしている。 ≪Description of drive means≫
The drive means 16 for driving and rotating the filter member 11 rotatably supported and accommodated between the upper and lower case portions 15a and 15b formed in this way has a motor 16a and the power of the motor 16a to the filter member 11. And a power transmission mechanism 16b for transmission.
The motor 16 a is installed on the upper case portion 15 a side via the motor support base 29.
The motor support base 29 is formed in a substantially bowl shape, and is screwed and installed on the corner portion outside (exhaust downstream side) of the upper case portion 15 a located on the opening center line of the window hole 27. Thus, the output shaft 30 of the motor 16a is made to protrude downward from the window hole 27 between the upper and lower case portions 15a and 15b.

このようにして、上側ケース部１５ａに設置されるモータ１６ａは、フード部１のスイッチ操作部９に備えられている図示省略のフィルタ清掃用スイッチに電気的に接続されている。
これにより、フィルタ清掃用スイッチのＯＮ操作によって起動し、動力伝達機構１６ｂを介してフィルタ部材１１を駆動回転させ、ＯＦＦ操作によって停止するようになっている。つまり、フィルタ清掃装置Ｂは、スイッチ操作部９のフィルタ清掃スイッチのＯＮ／ＯＦＦ操作によって、運転を開始、停止するように構成されている。 In this way, the motor 16a installed in the upper case portion 15a is electrically connected to a filter cleaning switch (not shown) provided in the switch operation portion 9 of the hood portion 1.
As a result, the filter cleaning switch is activated by an ON operation of the filter cleaning switch, and the filter member 11 is driven to rotate through the power transmission mechanism 16b and stopped by an OFF operation. That is, the filter cleaning device B is configured to start and stop operation by an ON / OFF operation of the filter cleaning switch of the switch operation unit 9.

動力伝達機構１６ｂは、フィルタ部材１１の清掃のときに、フィルタ部材１１を駆動回転させる上で最適な回転角速度にモータ１６ａの回転速度を変換する役目を成す。
この動力伝達機構１６ｂは、モータ１６ａの出力軸３０に取り付けられる第１の歯車３１と、フィルタ部材１１の外周に沿って取り付けられる第２の歯車３２とを備えて構成されている。
第１の歯車３１は、所定の外径を有するピニオンギア（小歯車）であり、モータ１６ａの出力軸３０に回転不能に固着される。 The power transmission mechanism 16b serves to convert the rotational speed of the motor 16a to an optimum rotational angular speed for driving and rotating the filter member 11 when the filter member 11 is cleaned.
The power transmission mechanism 16 b includes a first gear 31 attached to the output shaft 30 of the motor 16 a and a second gear 32 attached along the outer periphery of the filter member 11.
The first gear 31 is a pinion gear (small gear) having a predetermined outer diameter, and is fixed to the output shaft 30 of the motor 16a so as not to rotate.

第２の歯車３２は、フィルタ部材１１の外周径に相当するリング径にて形成されているリング部材の外周に刻設されるラックギア（大歯車）であり、フィルタ部材１１の外周にリング部材をネジ止めなどによって取り付けることで、当該外周に沿って備えられるようになっている。   The second gear 32 is a rack gear (large gear) engraved on the outer periphery of the ring member formed with a ring diameter corresponding to the outer diameter of the filter member 11, and the ring member is disposed on the outer periphery of the filter member 11. By being attached by screwing or the like, it is provided along the outer periphery.

また、第２の歯車３２が形成されるリング部材の外周には、第２の歯車３２が形成される外周部分を除いて一回りほど大きい外径にて突出させたリング外周縁部が設けられている。
これにより、リング外周縁部を円周数ヶ所の歯車支持部材２８の掴持部２８ａに対して掴持させて、フィルタ部材１１をフィルタケース１５内に、回転支軸部材４３を支点に回転可能に支持収容し得るようにしている。つまり、モータ１６ａの動力よって駆動回転し得るようにフィルタ部材１１をフィルタケース１５内に回転可能に支持収容させる。 Further, the outer periphery of the ring member on which the second gear 32 is formed is provided with an outer peripheral edge of the ring that protrudes with a larger outer diameter except for the outer peripheral portion on which the second gear 32 is formed. ing.
As a result, the outer peripheral edge of the ring can be gripped with respect to the gripping portions 28a of the gear support members 28 at several locations around the ring, and the filter member 11 can be rotated within the filter case 15 and the rotary support shaft member 43 can be rotated as a fulcrum. It can be supported and accommodated. That is, the filter member 11 is rotatably supported and accommodated in the filter case 15 so as to be driven and rotated by the power of the motor 16a.

≪付着物除去手段の説明≫
図８は、付着物除去手段を示す分解斜視図であり、図９は、フィルタ部材の清掃時における付着物除去部材のフィルタ部材への圧接状態を示す説明図である。ここでは、図２および図３を適宜参照しながら説明する。
なお、図９において、紙面上側が排気風路１０の排気下流側となり、紙面下側が排気風路１０の排気上流側となる。
付着物除去手段１７は、清掃時に駆動回転するフィルタ部材１１の排気風路１０の排気上流側に面する上流側フィルタ面１１ａおよび各通気部１２の空気衝突面部１２ａなどに付着されている油脂分や塵埃などの汚れを掻き落とすように取り除くものである。
この付着物除去手段１７は、フィルタ部材１１の上流側フィルタ面１１ａ側の凸凹面（上流側フィルタ面１１ａと、この上流側フィルタ面１１ａから排気下流側に向けて凹状の空気衝突面部１２ａとからなる凸凹面）に沿わせて線状または面状に圧接させる付着物除去部材１７ａと、この付着物除去部材１７ａを上流側フィルタ面１１ａに圧接させた状態で支持する支持部材１７ｂとを備えて構成されている。 ≪Explanation of deposit removal means≫
FIG. 8 is an exploded perspective view showing the deposit removing means, and FIG. 9 is an explanatory view showing a pressure contact state of the deposit removing member to the filter member during cleaning of the filter member. Here, description will be made with reference to FIGS. 2 and 3 as appropriate.
In FIG. 9, the upper side of the paper is the exhaust downstream side of the exhaust air passage 10, and the lower side of the paper is the exhaust upstream side of the exhaust air passage 10.
The adhering matter removing means 17 is an oil and fat component adhering to the upstream filter surface 11a facing the exhaust upstream side of the exhaust air passage 10 of the filter member 11 driven and rotated during cleaning, the air collision surface portion 12a of each ventilation portion 12, and the like. It removes dirt such as dust and dirt.
The adhering matter removing means 17 includes a convex / concave surface (upstream filter surface 11a on the upstream filter surface 11a side of the filter member 11 and an air collision surface portion 12a that is concave from the upstream filter surface 11a toward the exhaust downstream side. And a support member 17b for supporting the deposit removing member 17a in pressure contact with the upstream filter surface 11a. It is configured.

≪付着物除去部材の説明≫
付着物除去部材１７ａは、上流側フィルタ面１１ａ側において、該上流側フィルタ面１１ａおよび空気衝突面部１２ａに適宜の弾性力にて圧接し、フィルタ部材１１の清掃時に上流側フィルタ面１１ａおよび空気衝突面部１２ａに付着している汚れをフィルタ部材１１の駆動回転に伴い掻き落とすように取り除く。
この付着物除去部材１７ａは、適宜の弾性を有する不燃性ゴム材などを用いて、フィルタ部材１１の半径に相当する長さで、所定の幅と厚さ（板厚）を有する略帯板状に形成されている。 ≪Explanation of deposit removal member≫
The adhering matter removing member 17a is in pressure contact with the upstream filter surface 11a and the air collision surface portion 12a on the upstream filter surface 11a side with an appropriate elastic force, and when the filter member 11 is cleaned, the upstream filter surface 11a and the air collision The dirt adhering to the surface portion 12a is removed so as to be scraped off as the filter member 11 is driven.
The deposit removing member 17a is made of a nonflammable rubber material having an appropriate elasticity and has a length corresponding to the radius of the filter member 11 and a substantially strip-like shape having a predetermined width and thickness (plate thickness). Is formed.

そして、付着物除去部材１７ａは、上流側フィルタ面１１ａと各通気部１２の空気衝突面部１２ａとからなる凸凹面に沿わせるように圧接させる圧接縁辺部３３に、凸部３３ａと凹部３３ｂとを備えている。
すなわち、付着物除去部材１７ａは、図８および図９に示すように、排気風路１０の排気下流側に向けた凹状の空気衝突面部１２ａに圧接させる凸部３３ａと、上流側フィルタ面１１ａに圧接させる凹部３３ｂとを長さ方向に交互に配設してなる凸凹形状に圧接縁辺部３３を形成している。 And the deposit | attachment removal member 17a has the convex part 33a and the recessed part 33b on the press-contacting edge part 33 which press-contacts along the uneven surface which consists of the upstream filter surface 11a and the air collision surface part 12a of each ventilation part 12. I have.
That is, as shown in FIG. 8 and FIG. 9, the deposit removing member 17 a is formed on the convex portion 33 a that presses against the concave air collision surface portion 12 a toward the exhaust downstream side of the exhaust air passage 10 and the upstream filter surface 11 a. The press-contact edge portion 33 is formed in a concave-convex shape in which the concave portions 33b to be press-contacted are alternately arranged in the length direction.

凸部３３ａは、図３の（ｂ）に示すフィルタ部材１１の回転中心部Ｐを中心とする各回転円周線Ｙと交差する位置において付着物除去部材１７ａの圧接縁辺部３３に設けられるものであり、上流側フィルタ面１１ａから空気衝突面部１２ａに至る高さで、空気衝突面部１２ａの凸状幅Ｌ１と略同じ突出幅にて形成されている。換言すれば、凸部３３ａは、２本の切込み縁１３の切込み間隔Ｌ２よりも狭い突出幅にて凹部３３ｂの間に形成されている。   The convex portion 33a is provided on the pressure contact edge portion 33 of the deposit removing member 17a at a position intersecting with each rotation circumferential line Y centering on the rotation center portion P of the filter member 11 shown in FIG. The height from the upstream filter surface 11a to the air collision surface portion 12a is substantially the same as the protruding width L1 of the air collision surface portion 12a. In other words, the convex portion 33a is formed between the concave portions 33b with a projecting width narrower than the cut interval L2 between the two cut edges 13.

また、凸部３３ａと各回転円周線Ｙと交差しない位置に設けられる凹部３３ｂとの境目には、図８に示すように、所定の長さ（深さ）の切目３４が設けられており、凹部３３ｂの底部から凸部３３ａは切り離された突出形態と成している。
これにより、凸部３３ａは、フィルタ部材１１の回転時（清掃時）において、図９の（ａ）に示すように、フィルタ部材１１の各回転円周線Ｙ上に沿って断続的に存在する空気衝突面部１２ａ（通気部１２）がフィルタ部材１１の駆動回転に伴い差し掛かったときには、突端側を僅かに弾性変形させた状態で空気衝突面部１２ａに圧接され、そして、図９の（ｂ）に示すように、空気衝突面部１２ａが通り過ぎて回転円周方向に連なる上流側フィルタ面１１ａが差し掛かったときには、切目３４によって凹部３３ｂと切り離されている根元側から大きく弾性変形せしめた状態となって凹部３３ｂとともに上流側フィルタ面１１ａに圧接されるようになっている。 Further, as shown in FIG. 8, a cut 34 having a predetermined length (depth) is provided at the boundary between the convex portion 33a and the concave portion 33b provided at a position not intersecting with each rotation circumferential line Y. The convex portion 33a is separated from the bottom of the concave portion 33b.
Thereby, the convex part 33a exists intermittently along each rotation circumference Y of the filter member 11, as shown to (a) of FIG. 9, when the filter member 11 rotates (at the time of cleaning). When the air collision surface part 12a (ventilation part 12) is approached with the drive rotation of the filter member 11, the protruding end side is slightly elastically deformed and is pressed against the air collision surface part 12a, and FIG. As shown in the figure, when the air filter surface 12a passes and the upstream filter surface 11a continuous in the circumferential direction of the rotation is approached, the recesses are largely elastically deformed from the root side separated from the recesses 33b by the cuts 34. 33b is pressed against the upstream filter surface 11a.

また、凸部３３ａは、突出幅が空気衝突面部１２ａの凸状幅Ｌ１と略同じで２本の切込み縁１３の切込み間隔Ｌ２よりも狭く形成されていることで、フィルタ部材１１の回転中（清掃中）に、２本の切込み縁１３に接触することを回避される。   Further, the protrusion 33a has a protrusion width that is substantially the same as the protrusion width L1 of the air collision surface portion 12a and is formed to be narrower than the cut interval L2 of the two cut edges 13, so that the filter member 11 is rotating ( During cleaning, contact with the two cutting edges 13 is avoided.

なお、図示を省略しているが、付着物除去部材１７ａを軟らかい不燃性ゴム材などを用いて形成した場合には、凸部３３ａと凹部３３ｂとの境目に切目３４を必ずしも入れる必要はない。つまり、フィルタ部材１１の清掃中、凸部３３ａが空気衝突面部１２ａ（通気部１２）間の上流側フィルタ面１１ａに差し掛かったとき、凸部３３ａが材料から得られる軟らかさによって大きく弾性変形することが期待できるからである。   In addition, although illustration is abbreviate | omitted, when the deposit | attachment removal member 17a is formed using a soft nonflammable rubber material etc., it is not necessary to always make the cut 34 in the boundary of the convex part 33a and the recessed part 33b. That is, during the cleaning of the filter member 11, when the convex portion 33a reaches the upstream filter surface 11a between the air collision surface portions 12a (ventilation portion 12), the convex portion 33a is greatly elastically deformed by the softness obtained from the material.
