を提供するにある。However, in the former case, there is a problem that the wire is liable to be broken due to consumption due to electric discharge, and further, it is difficult to perform terminal treatment for fixing both ends, and great care must also be taken in mounting. In the latter case, there is no danger of wire breakage due to wear, but the cost of the molded product provided for mounting is large. The fact that the molding must be performed according to the required length has a particularly great effect on costs. The present invention has been made in view of such a point, and an object of the present invention is to provide a discharge device which is free from disconnection due to wear, has low manufacturing costs, and is easy to mount.

A wire-like electrode wire is inserted through and fixed to the small hole, and a spring for applying a pulling force is connected and stretched to the small hole on the other end side. [Operation] According to the present invention, it is possible to perform mounting without slack using the small holes provided in the discharge electrode. In the case of cutting a long piece, a piece having a different length can be easily obtained only by changing the cutting length. [Embodiment] Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. As shown in FIG.
, The return electrode plate 2 and the fixed frame 3 constitute a discharge unit. The discharge electrode 1 is in the form of an extremely thin strip having a thickness of about 0.04 mm, and has a number of small holes 10 perforated at equal intervals, and a number of small protrusions 11 arranged at equal intervals on one side edge. As shown in FIG. 7, a small hole 10 and a small projection are punched out of a metal hoop material.
11 is formed by cutting a long object formed. The counter electrode plate 2 is formed by cutting and raising a single metal plate 20, and is arranged on both sides of a window 21 formed by cutting and raising. The fixed frame 3 has a rectangular shape made of an insulator to which the discharge electrode 1 and the counter electrode plate 2 are attached, and integrally includes a plurality of bars 30 crossing the central opening. It has one mounting portion 31,32. As shown in FIG. 5, the mounting portion 31 of the mounting portions 31 and 32 has a groove 33 for locking the wire-shaped electrode wire 4 inserted into the small hole 10 at one end of the discharge electrode 1. And a plurality of ribs 34 arranged in a zigzag pattern provided to prevent the discharge electrode 1 from tilting, as shown in FIG. As shown in FIG. 4, the mounting portion 32 has a hook boss 36 to which the other end of a tension spring 35 having one end locked to the small hole 10 at the other end of the discharge electrode 1 is locked.
And a plurality of ribs 37 arranged in a zigzag pattern provided to prevent the discharge electrode 1 from tilting. That is, the discharge electrode 1 is fixed at one end via the electrode wire 4 and fixed at the other end via the extension spring 35, so that the discharge electrode 1 is attached in a state where tension is applied by the extension spring 35 and the ribs 34, The inclination is prevented from being caused by 37, and the discharge electrode 1 is provided for fixing the discharge electrode 1 to the fixed frame 3 regardless of whether the electrode wire 4 or the tension spring 35 is used. Small hole 10
It is something that uses. The counter electrode plate 2 is attached by being screwed to one surface of the fixed frame 3. When the discharge electrode 1 and the counter electrode plate 2 are mounted on the fixed frame 3 in this manner, FIGS. As shown in the figure, the discharge electrode 1 is located on the crosspiece 30 and between the pair of counter electrode plates 2. FIGS. 8 and 9 show an electrostatic precipitating air purifier 6 provided with the above-described discharge device.
A pre-filter 63, a discharge device, and a filter 7 are disposed in this order from the front side between the motor 61 and the fan 62 disposed on the rear side. The pre-filter 63 is for removing large dust, and the filter 7 is provided with a corrugated dust filter 71 and a deodorant filter 72 as shown in FIG. The filter material 71 for dust removal here is called a fiber filter made of a non-woven fabric such as a polypropylene fiber or a polyester fiber, and has a conductive portion 74 serving as a ground electrode on one surface side. A valley on one side of the dust removing filter material 71 is filled with a granular deodorizing filter material 72 made of activated carbon, and a cover 73, which is a breathable sheet made of non-woven fabric, is attached on one surface. Material 72 is covered. Now, if the fan 62 is driven to suck air from the suction port 60, large dust is removed by the pre-filter 63, and then the discharge electrode 1 and the counter electrode plate 2 to which a high voltage of about 6500V is applied in the discharge device. The dust particles in the air are charged by the corona discharge between them, and the charged particles are collected by the dust removing filter material 71 provided in contact with the conductive portion 74 which is the ground electrode of the filter 7, and then the deodorizing filter material 2 The air that comes in contact with the odor is removed of odor.
