例えばスキャナ装置等の光学電子機器は、機器筐体の構
成部品に対する塵埃の付着によって画像安定性および光
量が低下することから、塵埃除去装置によって機器筐体
内に対する塵埃の侵入が阻止される。For example, in an optical electronic device such as a scanner device, the image stability and the amount of light are reduced due to the adhesion of dust to the component parts of the device housing, so that the dust removing device prevents the intrusion of dust into the device housing.
従来、この種の塵埃除去装置には、空気導入口および空
気導出口を有する筐体と、この筐体の空気導入口に塵埃
を捕捉するエアフィルタと、このエアフィルタの空気下
流側に設けられ外気を導入するファンとを備えたものが
採用されている。Conventionally, this type of dust removing device is provided with a housing having an air inlet and an air outlet, an air filter for capturing dust in the air inlet of the housing, and an air downstream side of the air filter. A fan equipped with a fan for introducing outside air is used.

捉されるため、筐体外には空気導出口から清浄空気が吹
き出される。In the dust removing device configured as described above, the outside air is guided by the fan to the air inlet port → inside the casing → air outlet port. At this time, since dust in the outside air is captured by the air filter, clean air is blown out of the housing through the air outlet.

おり、このため長期間に亘る使用によってエアフィルタ
に目詰まりが生じ、除去能力が低下して筐体内の空気流
れを悪くしていた。この結果、清掃回数が増加し、メン
テナンスコストが嵩むという問題があった。However, in the conventional dust removing device, an air filter having a small mesh size is usually used, and therefore, the air filter is clogged due to long-term use, and the removing ability is deteriorated to reduce the internal capacity of the housing. The air flow was bad. As a result, there is a problem that the number of cleanings increases and maintenance cost increases.
本発明はこのような事情に鑑みてなされたもので、清掃
回数を確実に低減することができ、もってメンテナンス
コストの低廉化を図ることができる塵埃除去装置を提供
するものである。The present invention has been made in view of the above circumstances, and provides a dust removing device capable of reliably reducing the number of cleanings and thus reducing the maintenance cost.

である。The dust removing device according to the present invention is provided with an air flow path connecting the air introduction port and the air discharge port in the housing, refracts this air flow path many times, and each flow path cross-sectional area is in the flow path direction. It is formed by a zigzag flow path that gradually increases along with the wall surface of the flow path by an electrostatic induction material.
本発明においては、外気が筐体内の空気流路を通過する
際に流路抵抗によって流路壁に外気中の塵埃が捕捉され
る。In the present invention, when the outside air passes through the air passage in the housing, the passage resistance causes the dust in the outside air to be captured by the passage wall.
以下、本発明の構成等を図に示す実施例によって詳細に
説明する。Hereinafter, the configuration and the like of the present invention will be described in detail with reference to the embodiments shown in the drawings.

筐体８の空気供給口に接続されている。FIG. 1 is a sectional view showing a dust removing device according to the present invention, and FIG.
The figure is also a perspective view showing a usage example of the dust removing device according to the present invention. In the figure, a housing indicated by reference numeral 1 has an air inlet port 2 and an air outlet port 3 that are open to the inside and outside, and an air flow path 4 that connects these inlet ports 2 and 3 is provided inside. There is. The air flow path 4 is composed of an inner side surface of the housing 1 and upper and lower surfaces of the inclined partition plates 5a to 5d, and is formed by a zigzag flow path that is bent many times. Further, the air flow path 4 is constituted by a flow path whose flow path cross-sectional area changes at each part in the streamline direction, and thereby changes the velocity of the air flow. The inclined partition plate
The material of 5a to 5d is preferably a resin material because the amount of trapped dust is increased by the static electricity generated when the dust passes through the air passage 4. Reference numeral 6 denotes a blower that introduces outside air into the housing and discharges the outside air to the outside of the housing, and is provided at the periphery of the opening of the air outlet 3. An air hose 7 for supplying air is connected to the air outlet 3 and the air supply port of the electronic equipment casing 8.
このように構成された塵埃除去装置においては、外気が
筐体１内の空気流路４を通過する際に流路抵抗によって

気流路４内を通過する塵埃は、傾斜仕切板5a〜5dの上側
面や筐体１の内側面（第１図に符号Ａで示す斜線部）に
付着して捕捉されるのである。In the dust removing device configured as described above, when the outside air passes through the air passage 4 in the housing 1, the dust in the outside air is captured on the passage wall surface 4a by the passage resistance. That is, the dust passing through the air flow path 4 adheres to and is captured by the upper side surfaces of the inclined partition plates 5a to 5d and the inner side surface of the housing 1 (the hatched portion indicated by reference symbol A in FIG. 1). .
したがって、本実施例においては、塵埃の捕捉量をエア
フィルタによる場合と比較して十分に大きくすることが
できるから、清掃回数を確実に低減することができる。Therefore, in the present embodiment, the amount of dust trapped can be made sufficiently large as compared with the case of using the air filter, so that the number of cleanings can be reliably reduced.
なお、本発明においては、空気流路４の曲折回数が多い
程塵埃の除去効果が高くなることは勿論である。In addition, in the present invention, it is needless to say that the more the number of bending of the air flow path 4 is, the higher the dust removing effect is.

なり、その捕捉量が増大する。As described above, according to the present invention, an air flow path that connects the air introduction port and the air discharge port is provided in the housing, and the air flow path is formed by a zigzag-shaped flow path that is bent many times. When the outside air passes through the air passage in the housing, the passage resistance captures dust in the outside air on the wall surface of the passage. Therefore, the amount of dust trapped can be made sufficiently large as compared with the case of using the air filter, so that the number of cleanings can be surely reduced and the maintenance cost can be reduced. Further, by forming the zigzag flow passage so that the cross-sectional area of the flow passage gradually increases along the flow passage direction, the velocity of the air flow immediately after being diverted at each inlet end of the zigzag flow passage. Is large, and then its speed gradually decreases, so that the dust that has slowed down in the flow path after being turned is more likely to be captured by the wall surface of the flow path. Moreover, by forming the flow path wall surface with a static electricity inducing material that is a material that causes static electricity,
The dust is easily attracted by the electrostatic force generated on the wall surface of the flow path, and the amount of trapped dust increases.
