Description

本発明は、加熱調理中に発生する排気ガス中の油煙に含まれる油脂を捕集回収するため、調理用レンジの上方に設置された排気フード内の排気ガス吸入口に配置して使用されるグリスフィルタに関する。 INDUSTRIAL APPLICABILITY The present invention is used by arranging it at an exhaust gas suction port in an exhaust hood installed above a cooking range in order to collect and collect oils and fats contained in oil smoke in exhaust gas generated during cooking. Regarding the grease filter.

厨房の排気フード内の排気ガス吸入口に配置されるグリスフィルタについては、従来、様々な構造、機能を有するものが提案されているが、本発明に関連するものとして、例えば、特許文献1に記載された「バッフル型グリスフィルター」などがある。 As for the grease filter arranged in the exhaust gas suction port in the exhaust hood of the kitchen, those having various structures and functions have been conventionally proposed, but as those related to the present invention, for example, in Patent Document 1. There is a described "baffle type grease filter" and the like.

前記「バッフル型グリスフィルター」においては、第1バッフルと第2バッフルとの間に略S字状に蛇行する油脂捕集路が形成され、この油脂捕集路において油煙の圧縮と膨張を繰り返し、圧縮過程により油煙の流速を増して油脂の粒子を高速でバッフル板に効率良く衝突させ、膨張過程により油脂の温度を下げて油脂の凝集を促進させ、脱脂効率を高めている。 In the "baffle type grease filter", an oil / fat collection path meandering in a substantially S shape is formed between the first baffle and the second baffle, and the oil smoke is repeatedly compressed and expanded in this oil / fat collection path. The flow velocity of the oil smoke is increased by the compression process to efficiently collide the particles of the oil and fat with the baffle plate at high speed, and the temperature of the oil and fat is lowered by the expansion process to promote the aggregation of the oil and fat, and the degreasing efficiency is improved.

実開昭57-152919号公報Jikkai Sho 57-152919

特許文献1に記載された「バッフル型グリスフィルター」を使用することにより、ある程度、油脂除去率(脱脂効率)を高めることができるのであるが、油脂除去率の向上、圧力損失の低減及び騒音の軽減は、今後も要請され続ける重要な課題である。 By using the "baffle type grease filter" described in Patent Document 1, the oil / fat removal rate (defatting efficiency) can be increased to some extent, but the oil / fat removal rate is improved, the pressure loss is reduced, and noise is reduced. Mitigation is an important issue that will continue to be requested.

そこで、本発明が解決しようとする課題は、油煙中の油脂除去率が高く、圧力損失の低減、騒音の軽減を図ることができるグリスフィルタを提供することにある。 Therefore, an object to be solved by the present invention is to provide a grease filter having a high oil / fat removal rate in oil smoke, which can reduce pressure loss and noise.

本発明に係るグリスフィルタは、
枠状部の内周領域に樋形状をした複数のフィルタ板がそれぞれの凹面部を同方向に向けた状態で隙間を隔てて平行に配列されたフロントバッフル並びにバックバッフルを、
前記フロントバッフル、前記バックバッフルをそれぞれ構成する前記フィルタ板同士が互いに平行をなすとともに前記フィルタ板の凹面部の一部が互いに対向するように係脱可能に配置したグリスフィルタにおいて、
前記バックバッフルの前記フィルタ板の凹面部の幅方向の中心に、前記フロントバッフルに向かって突出した突状部を備え
前記フロントバッフルの枠状部と前記バックバッフルの枠状部とが重なり合う領域に前記バックバッフルの枠状部から前記フロントバッフルの枠状部を貫通して前記フロントバッフルの正面に突出する取っ手を備え、前記取っ手が前記バックバッフルの枠状部に収納可能であることを特徴とする。
The grease filter according to the present invention is
A front baffle and a back baffle in which a plurality of gutter-shaped filter plates are arranged in parallel across a gap with their concave portions facing in the same direction in the inner peripheral region of the frame-shaped portion.
In a grease filter arranged so that the filter plates constituting the front baffle and the back baffle are parallel to each other and a part of the concave surface portion of the filter plate faces each other so as to be removable.
A protruding portion protruding toward the front baffle is provided at the center of the concave portion of the filter plate of the back baffle in the width direction .
A handle that penetrates the frame-shaped portion of the front baffle from the frame-shaped portion of the back baffle and projects to the front of the front baffle is provided in the region where the frame-shaped portion of the front baffle and the frame-shaped portion of the back baffle overlap. The handle can be stored in the frame-shaped portion of the back baffle .

このような構成とすれば、フロントバッフルのフィルタ板の隙間からバックバッフルのフィルタ板の凹面部に向かって流入する排気ガスは突状部に接触した後、二つの方向に分かれ、流路に逆らうことなく、流速を上げながら、それぞれバックバッフルのフィルタ板の凹面部に沿って流動するので、フィルタ板との接触機会が増加し、油煙中の油脂除去率が高まる。また、排気ガスが流路に逆らわず流動するので、圧力損失が低下し、騒音も低減する。 With such a configuration, the exhaust gas flowing from the gap between the filter plates of the front baffle toward the concave portion of the filter plate of the back baffle comes into contact with the protruding portion and then splits in two directions and opposes the flow path. Without increasing the flow velocity, the gas flows along the concave surface of the filter plate of the back baffle, so that the chance of contact with the filter plate increases and the oil removal rate in the oil smoke increases. Further, since the exhaust gas flows without going against the flow path, the pressure loss is reduced and the noise is also reduced.

前記グリスフィルタにおいては、前記突状部の頂上部が前記フロントバッフルのフィルタ板の正面よりも前記バックバッフル寄りに位置することが望ましい。 In the grease filter, it is desirable that the top of the protruding portion is located closer to the back baffle than the front surface of the filter plate of the front baffle.

このような構成とすれば、グリスフィルタに進入した油煙が通動する流路が急激に縮小するので、油煙中の油脂除去効率が向上する。なお、突状部の頂上部がフロントバッフルの正面よりもバックバッフルから離れた位置にある場合(突状部の頂上部がフロントバッフルの正面から突出している場合)は、突状部により二分された油煙が、二分された流路内でフィルタ板面に接触する機会が減るので、フィルタ板面への付着による油脂除去率の向上に寄与しない。また、フィルタ板面への付着により油煙から除去された油脂はフィルタ板の突状部を伝わってバックバッフルから効率良く下部へ誘導されるが、頂上部がフロントバッフルのフィルタ板の正面よりも突出していると、誘導されずに頂上部から厨房室内に滴下するおそれがある。 With such a configuration, the flow path through which the oil smoke that has entered the grease filter passes is sharply reduced, so that the efficiency of removing oil and fat in the oil smoke is improved. If the top of the protrusion is farther from the back baffle than the front of the front baffle (when the top of the protrusion protrudes from the front of the front baffle), it is divided into two by the protrusion. Since the chance of the oil smoke coming into contact with the filter plate surface in the divided flow path is reduced, it does not contribute to the improvement of the oil / fat removal rate due to the adhesion to the filter plate surface. In addition, the oil and fat removed from the oil smoke due to the adhesion to the filter plate surface is efficiently guided from the back baffle to the lower part along the protruding part of the filter plate, but the top protrudes from the front of the filter plate of the front baffle. If so, there is a risk of dripping from the top into the kitchen room without being guided.

前記グリスフィルタにおいては、前記突状部の横断面形状が前記フィルタ板の凹面部の幅方向の中心線を挟んで鏡面対称をなしていることが望ましい。 In the grease filter, it is desirable that the cross-sectional shape of the protruding portion is mirror-symmetrical with the center line in the width direction of the concave portion of the filter plate interposed therebetween.

このような構成とすれば、突状部に接触した排気ガスは二つの方向に均等に分流して流動するので、排気ガスの偏った流入、流動が抑制され、油脂除去率の向上に有効である。 With such a configuration, the exhaust gas in contact with the projecting portion is evenly divided and flows in two directions, so that the uneven inflow and flow of the exhaust gas are suppressed, which is effective in improving the oil removal rate. be.

前記グリスフィルタにおいては、前記突状部の横断面形状が、山形、鋭角山形、半円形、半楕円形、曲線楔形、半多角形若しくは平板形の何れか1以上を含むものとすることができる。 In the grease filter, the cross-sectional shape of the protruding portion may include any one or more of a chevron, an acute angle chevron, a semicircle, a semi-elliptical shape, a curved wedge shape, a semi-polygonal shape, and a flat plate shape.

このような構成とすれば、油煙が突状部に接触する機会が増えるので、油脂除去率の向上に有効である。 With such a configuration, the chance of oil smoke coming into contact with the protruding portion increases, which is effective in improving the oil / fat removal rate.

前記グリスフィルタにおいては、前記フロントバッフルの枠状部と前記バックバッフルの枠状部とが重なり合う領域に前記バックバッフルの枠状部から前記フロントバッフルの枠状部を貫通して前記フロントバッフルの正面に突出する取っ手を備え、前記取っ手が前記バックバッフルの枠状部に収納可能である。 In the grease filter, the front surface of the front baffle penetrates from the frame-shaped portion of the back baffle to the frame-shaped portion of the front baffle in the region where the frame-shaped portion of the front baffle and the frame-shaped portion of the back baffle overlap. The handle is provided so as to protrude from the back baffle, and the handle can be stored in the frame-shaped portion of the back baffle .

このような構成とすれば、前記バックバッフルの枠状部に取っ手を収納することにより、当該枠状部から突出する部材を減らすことができるので、保管中、運搬中の省スペースを図ることができる。 With such a configuration, by storing the handle in the frame-shaped portion of the back baffle, the number of members protruding from the frame-shaped portion can be reduced, so that space can be saved during storage and transportation. can.

前記グリスフィルタにおいては、前記取っ手が、コ字状をなす本体部と、その両端に形成されたフック部とを有し、前記バックバッフルの枠状部に開設された複数の開口部に前記取っ手のフック部側がそれぞれ進退可能に挿入されることが望ましい。 In the grease filter, the handle has a U-shaped main body portion and hook portions formed at both ends thereof, and the handle is provided in a plurality of openings opened in the frame-shaped portion of the back baffle. It is desirable that the hook portions of the above are inserted so that they can move forward and backward.

このような構成とすれば、従来のグリスフィルタの製造工程において実施されていた、取っ手をスポット溶接により枠状部に固定する工程を無くすことができるので、工数削減を図ることができる。なお、フック部の形状は限定しないので、コ字状部分の両端を外側に曲げるハット曲げ、あるいは、コ字状部分の両端を内側に曲げるC字曲げなどを採用することができる。 With such a configuration, it is possible to eliminate the step of fixing the handle to the frame-shaped portion by spot welding, which has been carried out in the conventional grease filter manufacturing process, so that the man-hours can be reduced. Since the shape of the hook portion is not limited, hat bending in which both ends of the U-shaped portion are bent outward, C-shaped bending in which both ends of the U-shaped portion are bent inward, and the like can be adopted.

本発明により、油煙中の油脂除去率が高く、圧力損失の低減、騒音の軽減を図ることができるグリスフィルタを提供することができる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a grease filter having a high oil / fat removal rate in oil smoke, which can reduce pressure loss and noise.

突状部52aは、フィルタ板52の凹面部52bの幅方向52wの中心線52wcに沿って形成され、フロントバッフル10に向かって突出している。突状部52aの横断面形状は山形であり、その頂上部52fは直角をなしている。突状部52aの横断面形状はフィルタ板52の凹面部52bの幅方向52wの中心線52wcを挟んで鏡面対称をなしている。 The protruding portion 52a is formed along the center line 52wc of the concave surface portion 52b of the filter plate 52 in the width direction 52w, and protrudes toward the front baffle 10. The cross-sectional shape of the projecting portion 52a is a chevron shape, and the top portion 52f thereof forms a right angle. The cross-sectional shape of the projecting portion 52a is mirror-symmetrical with the center line 52wc of the concave surface portion 52b of the filter plate 52 in the width direction 52w interposed therebetween.

図10に示すように、フロントバッフル10の背面側と、バックバッフル50の正面側と、を対向させて重ね合わせると、フロントバッフル10の枠状部11の内側にバックバッフル50の枠状部51が内接した状態で両者が係脱可能に接合され、図1に示すグリスフィルタ100が形成される。 As shown in FIG. 10, when the back side of the front baffle 10 and the front side of the back baffle 50 are opposed to each other and overlapped with each other, the frame-shaped portion 51 of the back baffle 50 is inside the frame-shaped portion 11 of the front baffle 10. The grease filter 100 shown in FIG. 1 is formed by joining them in an inscribed state so as to be detachably joined.

フロントバッフル10の枠状部11の左右の平板部11t,11tと、バックバッフル50の枠状部51の左右の平板部51t,51tとが重なり合う領域にバックバッフル50の枠状部51の平板部51tからフロントバッフル10の枠状部11の平板部11tを貫通してフロントバッフル10の正面側に突出する取っ手55を備えている。 The flat plate portion of the frame-shaped portion 51 of the back baffle 50 overlaps with the left and right flat plate portions 11t and 11t of the frame-shaped portion 11 of the front baffle 10 and the left and right flat plate portions 51t and 51t of the frame-shaped portion 51 of the back baffle 50. It is provided with a handle 55 that penetrates the flat plate portion 11t of the frame-shaped portion 11 of the front baffle 10 from 51t and projects to the front side of the front baffle 10.

フロントバッフル10とバックバッフル50とを接合する過程において、バックバッフル50の左右の平板部51t,51tから突出した取っ手55,55のコ字状の本体部55a,55aが、フロントバッフル10の左右の開口部11u,11uを背面側から正面側に向かって貫通し、接合後は、図1に示すように、フロントバッフル10の左右の平板部11t,11tから突出した状態となる。 In the process of joining the front baffle 10 and the back baffle 50, the U-shaped main bodies 55a and 55a of the handles 55 and 55 protruding from the left and right flat plate portions 51t and 51t of the back baffle 50 are left and right of the front baffle 10. The openings 11u and 11u are penetrated from the back surface side to the front surface side, and after joining, they are in a state of protruding from the left and right flat plate portions 11t and 11t of the front baffle 10 as shown in FIG.

フロントバッフル10を構成する複数のフィルタ板12の配置間隔と、バックバッフル50を構成する複数のフィルタ板52の配置間隔とは同じであるが、配置位相がフィルタ板1枚分偏移しているので、図1に示すように、フロントバッフル10とバックバッフル50とを接合すると、図4,図5に示すように、フロントバッフル10のフィルタ板12と、バックバッフル50のバッフル板52とは互いに平行をなすとともに、フィルタ板12の凹面部12bの一部とフィルタ板52の凹面部52bの一部とが互いに対向した状態となる。 The arrangement interval of the plurality of filter plates 12 constituting the front baffle 10 and the arrangement interval of the plurality of filter plates 52 constituting the back baffle 50 are the same, but the arrangement phase is shifted by one filter plate. Therefore, when the front baffle 10 and the back baffle 50 are joined as shown in FIG. 1, the filter plate 12 of the front baffle 10 and the baffle plate 52 of the back baffle 50 are mutually as shown in FIGS. 4 and 5. In parallel with each other, a part of the concave surface portion 12b of the filter plate 12 and a part of the concave surface portion 52b of the filter plate 52 are in a state of facing each other.

具体的には、フロントバッフル10とバックバッフル50とを接合すると、図5に示すように、フロントバッフル10のフィルタ板12の隙間S1の幅方向の中央部分と、バックバッフル50のフィルタ板52の突状部52aの頂上部52fとが対向した状態となり、バックバッフル50のフィルタ板52の隙間S2と、フロントバッフル10の正面部12aの凹面部12b側とが対向した状態となる。また、図5に示すように、突状部52aの頂上部52fはフロントバッフル10のフィルタ板12の正面部12aよりもバックバッフル50寄り(背面側)に位置している。 Specifically, when the front baffle 10 and the back baffle 50 are joined, as shown in FIG. 5, the central portion in the width direction of the gap S1 of the filter plate 12 of the front baffle 10 and the filter plate 52 of the back baffle 50. The top portion 52f of the protruding portion 52a faces the top 52f, and the gap S2 of the filter plate 52 of the back baffle 50 and the concave portion 12b side of the front portion 12a of the front baffle 10 face each other. Further, as shown in FIG. 5, the top portion 52f of the protruding portion 52a is located closer to the back baffle 50 (back side) than the front portion 12a of the filter plate 12 of the front baffle 10.

次に、図4~図7を参照して、図1~図3に示すグリスフィルタ100の機能、効果などについて説明する。グリスフィルタ100は、加熱調理中に発生する排気ガス中の油煙に含まれる油脂を捕集回収するため、調理用レンジの上方に設置された排気フード内の排気ガス吸入口に配置して使用される。加熱調理中に発生する排気ガスは、図1,図4,図6,図7中に示すように、矢印Gで示す方向に沿ってグリスフィルタ100のフロントバッフル10側から流入し、グリスフィルタ100内を流動して、バックバッフル50側から流出する。 Next, the functions, effects, and the like of the grease filters 100 shown in FIGS. 1 to 3 will be described with reference to FIGS. 4 to 7. The grease filter 100 is used by arranging it at the exhaust gas suction port in the exhaust hood installed above the cooking range in order to collect and collect the oil and fat contained in the oil smoke in the exhaust gas generated during cooking. To. As shown in FIGS. 1, 4, 6, and 7, the exhaust gas generated during cooking flows in from the front baffle 10 side of the grease filter 100 along the direction indicated by the arrow G, and the grease filter 100 is generated. It flows inside and flows out from the back baffle 50 side.

具体的には、図4~図6に示すように、矢印Gに沿って流動してきた排気ガスはフロントバッフル10のフィルタ板12の隙間S1に流れ込み、バックバッフル50のフィルタ板52の突状部52aの頂上部52fに接触した後、二つの方向に分かれ、フィルタ板12とフィルタ板52との対向部分の隙間S3を通過して、フロントバッフル10の凹面部12b側へ流れ込み、反対方向から流れ込む排気ガスと接触、合流することによって互いの流動方向が変化し、バックバッフル50のフィルタ板52の隙間S2を通過して流出する。 Specifically, as shown in FIGS. 4 to 6, the exhaust gas flowing along the arrow G flows into the gap S1 of the filter plate 12 of the front baffle 10, and the protruding portion of the filter plate 52 of the back baffle 50. After contacting the top 52f of 52a, it is divided into two directions, passes through the gap S3 of the facing portion between the filter plate 12 and the filter plate 52, flows into the concave portion 12b side of the front baffle 10, and flows from the opposite direction. By contacting and merging with the exhaust gas, the flow directions of each other change, and the gas flows out through the gap S2 of the filter plate 52 of the back baffle 50.

図6に示すように、バックバッフル50のフィルタ板52の突状部52aの頂上部52fに接触して二方向に分流した排気ガスは、突状部52aの斜面部分、正面部12c、隔壁部52d及び突縁部52eに、順次、連続的に接触し、流速を上げながら流動するので、フィルタ板52の凹面部52bとの接触機会が増加し、排気ガスに含まれる油煙中の油脂除去率を高めることができる。 As shown in FIG. 6, the exhaust gas that has come into contact with the top portion 52f of the protruding portion 52a of the filter plate 52 of the back baffle 50 and has been diverted in two directions is the slope portion, the front portion 12c, and the partition wall portion of the protruding portion 52a. Since the 52d and the ridge portion 52e are sequentially and continuously contacted and flow while increasing the flow velocity, the chance of contact with the concave surface portion 52b of the filter plate 52 increases, and the oil and fat removal rate in the oil smoke contained in the exhaust gas increases. Can be enhanced.

即ち、図6に示すように、グリスフィルタ100のフロントバッフル10のフィルタ板12の隙間S1からバックバッフル50のフィルタ板52の凹面部52bに向かって流入する排気ガスは突状部52aの頂上部52fに接触することによって二つの方向に分かれ、流路に逆らうことなく、それぞれフィルタ板52の凹面部52bの広範囲に沿って流動するので、フィルタ板52との接触機会が多いのがわかる。 That is, as shown in FIG. 6, the exhaust gas flowing from the gap S1 of the filter plate 12 of the front baffle 10 of the grease filter 100 toward the concave surface portion 52b of the filter plate 52 of the back baffle 50 is the top of the protruding portion 52a. By contacting the 52f, it is divided into two directions and flows along a wide range of the concave surface portion 52b of the filter plate 52 without going against the flow path, so that it can be seen that there are many opportunities for contact with the filter plate 52.

また、フロントバッフル10のフィルタ板12の隙間S1からバックバッフル50のフィルタ板52の凹面部52bに向かって流入した排気ガスは突状部52aの頂上部52fに接触した後、二つの方向に分かれ、流路に逆らうことなく、それぞれバックバッフル50のフィルタ板52の凹面部52bに沿って流動する。このため、図7に示すように、圧力の高い領域は、突状部52aの頂上部52fの正面付近(符号X1で示す領域)及び突状部52fの裾野付近(符号X2で示す領域)の比較的狭い範囲に限られることとなり、その結果、圧力損失が低下し、騒音も低減する。なお、図7中に記載されている数値の単位はPaである。 Further, the exhaust gas flowing from the gap S1 of the filter plate 12 of the front baffle 10 toward the concave surface portion 52b of the filter plate 52 of the back baffle 50 contacts the top portion 52f of the protruding portion 52a and then is divided into two directions. , Flows along the concave surface portion 52b of the filter plate 52 of the back baffle 50 without going against the flow path. Therefore, as shown in FIG. 7, the high pressure region is located near the front surface of the top portion 52f of the projecting portion 52a (region indicated by reference numeral X1) and near the foot of the projecting portion 52f (region indicated by reference numeral X2). It will be limited to a relatively narrow range, resulting in reduced pressure loss and noise. The unit of the numerical value shown in FIG. 7 is Pa.

次に、図8,図9を参照し、従来のグリスフィルタにおける排気ガスの流動状態及び圧力分布状態について説明する。図8は従来のグリスフィルタを通過する排気ガスの流動状態を示す図であり、図9は従来のグリスフィルタを通過する排気ガスの圧力分布状態を示す図である。なお、図9中に記載されている数値の単位はPaである。 Next, with reference to FIGS. 8 and 9, the flow state and pressure distribution state of the exhaust gas in the conventional grease filter will be described. FIG. 8 is a diagram showing a flow state of the exhaust gas passing through the conventional grease filter, and FIG. 9 is a diagram showing a pressure distribution state of the exhaust gas passing through the conventional grease filter. The unit of the numerical value shown in FIG. 9 is Pa.

図8に示すように、従来のグリスフィルタにおいては、フロントバッフルのフィルタ板62の隙間S1からバックバッフルのフィルタ板72の凹面部72bに向かって流入した排気ガスは平板状の正面部72aよりも正面側に離れた部分において、二つの方向に分かれて流動しているため、フィルタ板72の正面部72aとの接触機会が少なく、排気ガスに含まれる油煙中の油脂除去率が低いことが分かる。 As shown in FIG. 8, in the conventional grease filter, the exhaust gas flowing from the gap S1 of the filter plate 62 of the front baffle toward the concave portion 72b of the filter plate 72 of the back baffle is more than the flat plate-shaped front portion 72a. It can be seen that in the portion separated from the front side, the flow is divided into two directions, so that there is little chance of contact with the front portion 72a of the filter plate 72, and the oil / fat removal rate in the oil smoke contained in the exhaust gas is low. ..

また、従来のグリスフィルタにおいては、フロントバッフルのフィルタ板62の隙間S1からバックバッフルのフィルタ板72の凹面部72bに向かって流入した排気ガスは平板状の正面部72aよりも正面側に離れた部分において二つの方向に分かれている。このため、図9に示すように、正面部72aの正面付近(符号Yで示す領域)の比較的広い範囲(図7中に示す符号X1,X2で示す領域より広い領域)において圧力が高くなっており、本実施形態のグリスフィルタ100に比べ、従来のグリスフィルタは、圧力損失が高く、騒音も大である。 Further, in the conventional grease filter, the exhaust gas flowing from the gap S1 of the filter plate 62 of the front baffle toward the concave surface portion 72b of the filter plate 72 of the back baffle is separated from the flat plate-shaped front portion 72a to the front side. The part is divided into two directions. Therefore, as shown in FIG. 9, the pressure becomes high in a relatively wide range (a region wider than the regions indicated by the reference numerals X1 and X2 shown in FIG. 7) in the vicinity of the front surface (the region indicated by the reference numeral Y) of the front portion 72a. Compared to the grease filter 100 of the present embodiment, the conventional grease filter has a high pressure loss and a large noise.

次に、図17に基づいて、バックバッフル50の取っ手55について説明する。図17(a)に示すように、取っ手55は、コ字状の本体部55aと、その両端部分に形成されたフック部55b,55bとを備えている。フック部55b,55bは本体部55aの両端部分からコ字の外側に直角に曲がった形状をなしており、ハット曲げによって形成されている。 Next, the handle 55 of the back baffle 50 will be described with reference to FIG. As shown in FIG. 17A, the handle 55 includes a U-shaped main body portion 55a and hook portions 55b and 55b formed at both ends thereof. The hook portions 55b and 55b have a shape that is bent at a right angle to the outside of the U-shape from both end portions of the main body portion 55a, and are formed by hat bending.

また、バックバッフル50の枠状部51の側縁部51sの平板部51t及び側面部51gに跨る領域に、取っ手55の本体部55aとフック部55bの境界部分及びフック部55bが挿通可能な一対のスリット状の開口部56,56が開設されている。 Further, a pair in which the boundary portion between the main body portion 55a and the hook portion 55b of the handle 55 and the hook portion 55b can be inserted into the region straddling the flat plate portion 51t and the side surface portion 51g of the side edge portion 51s of the frame-shaped portion 51 of the back baffle 50. Slit-shaped openings 56, 56 are opened.

図17(a)に示すように、取っ手55のフック部55b,55b寄りの部分を、側縁部51sの側面部51gからそれぞれ開口部56,56に近づけ、図17(b)に示すように、取っ手55のフック部55b,55b寄りの部分をそれぞれ開口部56,56に挿入すると、取っ手55が側縁部51sに装着される。 As shown in FIG. 17A, the portions of the handle 55 near the hook portions 55b and 55b are brought closer to the openings 56 and 56 from the side surface portions 51g of the side edge portions 51s, respectively, and as shown in FIG. 17B. When the portions of the handle 55 near the hook portions 55b and 55b are inserted into the openings 56 and 56, respectively, the handle 55 is attached to the side edge portion 51s.

この後、取っ手55の本体部55aを、側縁部51sの平板部51tに向かって押圧すると、図17(c)に示すように、取っ手55が側縁部51s内に収納される。また、収納された取っ手55の本体部55aを引っ張れば、取っ手55は図17(b)に示す状態に復帰する。 After that, when the main body portion 55a of the handle 55 is pressed toward the flat plate portion 51t of the side edge portion 51s, the handle 55 is housed in the side edge portion 51s as shown in FIG. 17 (c). Further, if the main body portion 55a of the stored handle 55 is pulled, the handle 55 returns to the state shown in FIG. 17 (b).

図17(c)に示すように、取っ手55をバックバッフル50の枠状部51の側縁部51に収納すれば、枠状部51から突出する部材を減らすことができるので、保管中、運搬中の省スペースを図ることができる。 As shown in FIG. 17C, if the handle 55 is housed in the side edge portion 51 of the frame-shaped portion 51 of the back baffle 50, the number of members protruding from the frame-shaped portion 51 can be reduced, so that the members can be transported during storage. It is possible to save space inside.

また、取っ手55は、コ字状をなす本体部55aと、その両端のフック部55b,55bを有し、バックバッフル50の枠状部51に開設された複数の開口部56,56に取っ手55のフック部55a,55a側がそれぞれ進退可能に挿入されている。 Further, the handle 55 has a U-shaped main body portion 55a and hook portions 55b and 55b at both ends thereof, and the handle 55 is provided in a plurality of openings 56 and 56 provided in the frame-shaped portion 51 of the back baffle 50. The hook portions 55a and 55a sides of the above are inserted so as to be able to advance and retreat, respectively.

従って、従来のグリスフィルタの製造工程において実施されていた、取っ手をスポット溶接により枠状部に固定する工程が不要となり、工数削減を図ることができる。なお、取っ手55のフック部55b,55bの形状は限定しないので、コ字状部分の両端を外側に曲げるハット曲げのほかに、コ字状部分の両端を内側に曲げるC字曲げなどを採用することもできる。 Therefore, the step of fixing the handle to the frame-shaped portion by spot welding, which has been carried out in the conventional grease filter manufacturing process, becomes unnecessary, and the man-hours can be reduced. Since the shapes of the hook portions 55b and 55b of the handle 55 are not limited, in addition to the hat bending that bends both ends of the U-shaped portion outward, a C-shaped bending that bends both ends of the U-shaped portion inward is adopted. You can also do it.
