良に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air cleaning device for railway vehicles and the like. More specifically, the present invention relates to an improvement of an electrode unit which is most suitable for use in an air cleaning device incorporated in an air conditioning system for railway vehicles or the like, or an indoor installation type thin air cleaning device.

号によって明らかにされている。[Prior Art] Regarding the purification of air in a passenger car by incorporating an electrostatic air purifying device into an existing cooling and heating device installed on the ceiling of a railroad vehicle, the applicant of the present application has proposed 1-245774
As revealed by the issue.
従来の静電式空気清浄装置の多くは、帯電々極（＋）の
周囲を（前段）集塵電極（−）で囲んで空気通路を形成
すると共に、後段に集塵電極（−）とフィルターとを配
置するようにしている。また、電極の前段にプレイフィ
ルターを配置するものも公知である。Many of the conventional electrostatic air purifiers have an air passage formed by surrounding the charged positive electrode (+) with a dust collecting electrode (-) (previous stage) and forming a dust collecting electrode (-) and a filter at the subsequent stage. I'm trying to place and. Further, it is also known that a play filter is arranged in front of an electrode.
［考案が解決しようとする課題］ 一般に、静電式の空気清浄装置の場合、帯電々極（＋）
と集塵電極（−）の材質や形状及び寸法によって集塵能
力に大巾な差が生じるので、その設計は極めて重要であ
る。[Problems to be Solved by the Invention] Generally, in the case of an electrostatic air purifier, a charged positive electrode (+) is used.
Since the dust collecting ability greatly varies depending on the material, shape and size of the dust collecting electrode (-), its design is extremely important.
従来の床設置型の静電式空気清浄装置では、奥行き寸法
を比較的大きくしてもよいので、プレフィルター・帯電
々極（＋）・集塵電極（−）・フィルターを直線状に配
列する寸法に自由度があり、殊に電極の形状を様々の態
様に設計することが可能であった。In a conventional floor-mounted electrostatic air purifier, the depth dimension may be relatively large, so the pre-filter, charging pole (+), dust collecting electrode (-), and filter are arranged linearly. There is a degree of freedom in size, and in particular, the shape of the electrode can be designed in various ways.
これに対して壁掛け型の静電式空気清浄装置などでは、
薄型に仕上げるために、奥行き寸法に限界があり、従っ
て、電極（＋）（−）の構造に制約がある。On the other hand, in a wall-mounted electrostatic air purifier, etc.,
In order to finish thin, there is a limit in the depth dimension, and therefore, there is a restriction in the structure of the electrodes (+) (-).
更に、鉄道車輌用の空気清浄装置、殊に、既存の冷暖房
装置に組み込んで利用するタイプのものでは、既存の冷
暖房装置の空気取入口、若しくは空気排出口部分を利用
せざるを得ないので、寸法的な制約から来る電極構造の
設計上の困難がある。Furthermore, an air cleaning device for railway vehicles, particularly, a type that is used by incorporating it into an existing cooling and heating device, is forced to use the air intake port or the air discharge part of the existing cooling and heating device. There are difficulties in designing the electrode structure due to dimensional constraints.
前記した本願出願人の先の出願のものでは、既存の鉄道
用冷暖房装置における空気の取入・排出口部分が、車輌
の天井面よりも下側に大きく突出したものであったため
に、この部分に組み込む電極（＋）（−）の設計に比較
的自由度があり、高い集塵性能のものを提供することが
可能であった。In the above-mentioned applicant's earlier application, the air intake / exhaust portion of the existing railway heating / cooling device is a portion that protrudes largely below the ceiling surface of the vehicle. The electrodes (+) and (-) to be incorporated in (1) and (2) were relatively flexible in design, and it was possible to provide a high dust collecting performance.
しかし、鉄道車輌にも様々なタイプのものがあり、例え
ば、改良型の新幹線用客車では、冷暖房装置における空
気の取入・排出口部分は、車輌の天井面から突出した部
分が薄く設計されており、下側に突出した部分の寸法が
従来のものに比較して大巾に小さな構造になっている。However, there are various types of railway vehicles, for example, in the improved passenger cars for Shinkansen, the air intake / exhaust ports of the air conditioning system are designed so that the parts protruding from the ceiling surface of the vehicle are thin. The size of the portion projecting downward is much smaller than that of the conventional one.
上記のような構造では、空気清浄装置を組み込むための
スペースが極めて狭溢なだけでなく、特に奥行き寸法が
小さく、従来の如き電極構造では、天井面よりも下側に
突出した部分を拡大しないと予定された集塵能力を発揮
することができない。しかし、天井面に大きな突出部を
形成することは車輌内部の統一的デザイン思想を破滅さ
せるものであり、到底採用できない問題である。In the structure as described above, not only the space for incorporating the air cleaning device is extremely narrow, but also the depth dimension is particularly small, and in the conventional electrode structure, the portion protruding below the ceiling surface is not enlarged. And it is not possible to exert the planned dust collection ability. However, forming a large protrusion on the ceiling surface destroys the unified design concept inside the vehicle, and is a problem that cannot be adopted at all.
本考案は上記に鑑み、電極の配列を極めて薄型にするこ

The main purpose is to clarify the air purification device for railway vehicles.

It is an object of the present invention to clarify an electrode structure of an improved air cleaning device that can be set and used in the mouth, the middle of an air duct, etc.
