二枚重ね、気流Xを曲折させて流し、油煙を捕集してい
た。Conventional Technology Ventilation devices such as ventilation fans and range hoods that exhaust oil smoke generated during cooking in the kitchen and prevent indoor air from becoming polluted are often heavily contaminated due to the oil smoke adhering to them.
It is necessary to clean frequently. In order to save this cleaning effort, a method is used in which a filter is attached to the front of the ventilation device to collect oily smoke to prevent the main body of the ventilation device from getting dirty, and only the filter is cleaned. Conventionally, in the case of a filter that uses inertial collision to collect oil smoke, as shown in FIGS. As shown in FIG. 8, two plates (slot mesh) 103 having openings 102 through which the airflow passes are stacked one on top of the other, and the airflow X is bent to flow to collect oil smoke.
この極のフィルターは、気流の流れの方向が二回かわり
、切り起こし101に確実に衝突するので(第8図にお
ける破線矢印)、油煙の捕集効率は高いものであった。In this polar filter, the direction of the airflow changed twice and the airflow reliably collided with the raised cut 101 (dashed line arrow in FIG. 8), so the oil smoke collection efficiency was high.
発明が解決しようとする問題点
前記、従来のフィルターでは、腐食性を考慮してアルミ
の板(板厚0.5mm)が用いられているが、二枚であ
るため高価であり、また清掃時においても、二枚のフィ
ルターの内側空間に付着した油煙は、洗浄することがで
きず、分解しなければ完全に清掃できないという不便さ
があった。Problems to be Solved by the Invention As mentioned above, in the conventional filter, aluminum plates (plate thickness 0.5 mm) are used in consideration of corrosion resistance, but since there are two plates, it is expensive, and it is difficult to clean the filter. In this case, the oil smoke that adhered to the inner space of the two filters could not be cleaned, and it was inconvenient that it could not be completely cleaned unless it was disassembled.
また、切り起こし101が切り起こし方向に平行に並ら
んでいるだめ、縦方向に切り起こしの存在しない閉孔部
104がありこの部分では気流Xは縦方向に流れても通
過すべき開孔がなく(第9図)、横方向の開孔102に
のみ入る(第10図)ため、気流が局部的に偏流し、通
過風速を大きく取ると笛音を発生するので、切り起こし
高さhを高くして開孔102を大きくしなければならな
かった。そのため、高い油煙捕集効率を得るためには、
フィルターとして2枚重ねる必要があった。In addition, since the cut and raised portions 101 are lined up parallel to the cut and raised direction, there is a closed hole portion 104 in which there is no cut and raised portion in the vertical direction, and in this portion, even if the airflow X flows in the vertical direction, there is no opening to pass through. (Fig. 9), and enters only the horizontal opening 102 (Fig. 10), so the airflow is locally biased, and if the passing wind speed is high, a whistling sound will be generated. It was necessary to increase the height and make the aperture 102 larger. Therefore, in order to obtain high oil smoke collection efficiency,
It was necessary to stack two filters.
本発明は、これら従来の問題点に留意し、油煙の捕集効
率が高く、安価でかつ清掃性にすぐれた換気装置用フィ
ルターを提供することを目的とするものである。The present invention takes these conventional problems into consideration and aims to provide a filter for a ventilation system that has high oil smoke collection efficiency, is inexpensive, and is easy to clean.

数の切シ起こしを設けて開孔を形成し、前記開孔の長手
方向に隣り合う間の閉孔部は、前記切り起こし方向の隣
に位置する開孔に対向する構成としたものである。Means for Solving the Problem - In order to solve this problem, the present invention provides a single flat plate with a large number of raised cuts to form apertures, and a hole is formed between adjacent holes in the longitudinal direction. The closed hole portion is configured to face the opening located next to the cut and raised direction.
作 用
この構成により、調理時に発生した油煙を含む空気は、
切シ起こし部によって形成された開孔を通気孔として通
過するが、閉孔部の対向する隣には開孔が存在するので
気流の偏流が少なくて、笛音の発生がなく、また前面側

構成されているので、容易に行うことができることとな
る。Effect: With this configuration, the air containing oil smoke generated during cooking is
The airflow passes through the opening formed by the cut and raised part as a ventilation hole, but since there is an opening next to the closed hole part, there is little bias in the airflow, and there is no whistling sound, and the front side The air containing oil smoke that enters from the inside cannot travel straight, but instead bends and escapes to the rear side, and in this process, the oil smoke is sufficiently collected. The filter can be easily cleaned since it is made up of a single plate.
実施例
以下、本発明の実施例を第1図〜第4図にもとづき説明
する。図において1はフィルターであり、板厚0.51
rrInのアルミの平板に、切シ起こし2を設けること
によって開孔3を形成したものである。Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 4. In the figure, 1 is a filter, with a plate thickness of 0.51
Openings 3 are formed by cutting and raising 2 on a flat plate of rrIn aluminum.
開孔3は横方向に20m+++の長さを有していて、5
間の閉孔部4をおいて再び開孔3になっている。The opening 3 has a length of 20 m+++ in the lateral direction, and has a length of 5
It becomes an open hole 3 again with a closed hole section 4 in between.

ある。Further, cut and raised holes 2 are provided at intervals of 2.5 in the vertical direction, and the formed openings 3 are located between vertically adjacent closed hole portions 4, so that the closed hole portions 4 are locally concentrated. It is in a dispersed form. The height b of the raised cut is 1 jsi, and the opening 3 is very small when viewed from the front side. FIG. 5 shows a state in which this filter 1 is incorporated into a ventilation fan. Reference numeral 6 denotes a frame body of the ventilation fan body, which is equipped with a motor 6 and blades 7 rotated by the motor 6. A filter 1 held by a filter frame 8 is disposed in front of the blade 7. In the figure, numeral 9 is an oil pan, 1o is a shutter, and 11 is a support member for the motor 6.

ることとなる。In the above configuration, the motor 6 rotates the blades 7 to allow air containing pollutants generated during cooking to pass through the filter 1 and be discharged outside. In the filter 1, since the airflow Y shown in FIGS. 2 to 4 is bent instead of going straight, large oil particles are reliably collected.
特に本発明のフィルター1では、開孔3が小さく、かつ

くるが、羽根7.シャッター10などとの衝突も少なく
大部分は室外に排出され、換気扇の本体部分の汚れは非
常に少なくなシ、清掃の手間が省ける。In particular, in the filter 1 of the present invention, the apertures 3 are small and the apertures 3 are not formed in the straight direction of the suction air flow Y, taking into consideration the rising airflow caused by high-temperature waste gas during cooking. By setting the mounting 9 at an angle, the oil smoke collection efficiency will be greatly improved. Also, small oil particles are not collected and enter the inside of the ventilation fan along with the airflow, but the blades 7. There is little collision with the shutter 10, etc., most of the air is discharged outside, and there is very little dirt on the main body of the ventilation fan, which saves the effort of cleaning.
そして、閉孔部4が局部的に集中せずに分散しているた
め、フィルター1に衝突する気流Yはすぐ近くの開孔3
に入るので(第3図)、偏流が起こシに<<、開孔3が
小さくても、笛音を生じにくくなくいる。Since the closed pores 4 are not locally concentrated but are dispersed, the airflow Y colliding with the filter 1 is directed to the nearby openings 4.
(Fig. 3), a drifting flow occurs.Even if the opening 3 is small, it is not difficult to generate a whistling sound.
また、フィルター1は一枚の板で構成されているので、
材料費が安く、さらに清掃の際二枚の場合のような分解
の作業もなく、清掃する面積も狭くなるので清掃性が向
上する。In addition, since the filter 1 is composed of a single plate,
The cost of materials is low, there is no disassembly work required when cleaning two sheets, and the area to be cleaned becomes smaller, improving cleaning efficiency.
なお、本実施例では換気装置として換気扇の場合を示し
たが、レンジフードであっても、その効果は同様に得ら
れる。In this embodiment, a ventilation fan is used as the ventilation device, but the same effect can be obtained with a range hood.
つぎに、本発明の他の実施例を第6図に示す。Next, another embodiment of the present invention is shown in FIG.
図においては、縦方向に隣り合う開孔3が、上部の開孔
3の左端と下部の開孔3の右端とが同一線上にある構成
