Abstract

PURPOSE:To lower pressure drop and to maintain dust collection performance by equipping a pleatlike electrostatic filter material between a first electrode and a second electrode. CONSTITUTION:When an electric field is generated between a first electrode 1 and a second electrode 2, an electrostatic filter material 3 is electrified with the electric field. The air is allowed to flow oppositely to the first electrode 1 and passed through a draft hole 1a. Dust contained in the air is attracted to the electrostatic filter material 3 and collected. This electrostatic filter material 3 is worked into a pleated shape and the surface area is increased. The contact part of the electrostatic filter material 3 and the electrodes 1, 2 is made little and leaked current is inhibited from being increased and tracking is made difficult to be generated. Thereby the filter is prolonged.

Conventional technology In recent years, many air purifiers that remove cigarette smoke and dust emitted into the air have been used to create a comfortable environment, and the lifespan of filters used in air purifiers has increased. The demand for this is increasing.

A conventional air purifier filter will be described with reference to FIGS. 7 and 8. In the first embodiment, as shown in FIG. 7, an electret material 18 which is itself electrically charged among electrostatic filter materials is used as an air filter, and air is caused to flow in the direction of the arrow to pass through the electret material 18. .

Dust particles in the air were blocked, and especially charged particles were removed using Coulomb force. In the second embodiment of the electrostatic dust collection air filter, air is passed between a first electrode 19 and a second electrode 2o made of a flat plate of metal such as aluminum, as shown in FIG.

Problems to be Solved by the Invention The conventional air filter of the first embodiment has a problem in that pressure loss is large because air is passed perpendicularly to the surface of the electret material 18. In particular, when the air filter becomes thicker due to the use of multiple layers of electret material or the combined use of a deodorizing filter, a fan motor (not shown) with high power is required to flow the air. For example, a cross-flow fan with low noise cannot be used, and a sirocco fan is required.
A large motor is required.

Further, if the charged particles adhere to the electret material 18, the charge on that part of the electret material 18 will be neutralized, so there is a problem that the life of the air filter is short. Furthermore, in the air filter of the second embodiment, the first
Since air is passed between the electrode plate 19 and the second electrode plate 2o, there is little pressure loss, and the life is extended due to electrostatic precipitate. However, electrode materials are expensive because they require a large amount of use and require many man-hours to process. In addition, in order to make the initial characteristics equivalent to those of the first embodiment, it is necessary to reduce the distance between the electrode plates, and if it is necessary to make it thin, it becomes very difficult both technically and in terms of yarn production. -!

To explain the operation in the above configuration, the first electrode 1 and the second electrode
An electric field is generated between the electrodes 2, the electrostatic filter material 3 is charged with an electric field, and the air flowing from the direction of the arrow opposite the first electrode 1 passes through the ventilation hole 12L of the first electrode 1, and the electrostatic filter material 3 is charged with an electric field. The collected dust is attracted to and collected by the electrostatic filter material 3. At this time, the electrostatic filter material 3 is pleated to increase its surface area, so the dust collection area is expanded and the pleated shape is increased. Since the processed electrostatic filter material 3 has few contact parts with the first electrode 1 and the second electrode 2, an increase in leakage current is suppressed and tracking becomes less likely to occur. Further, the electrostatic filter material 3 has a long lifespan in dust collection performance due to the effect of discharging charges accumulated during dust collection, the effect of suppressing charging during dust collection, and the dielectric action caused by the electric field.

As shown in the figure, a large number of holes 6 are provided in a pleated electrostatic filter material 6. When the height of the pleats becomes 7H or less, the effect of reducing pressure loss becomes a little smaller due to the margins of the folded parts, so it is necessary to use a large number of holes 6.

As shown in the figure, a cut portion 9 is provided by cutting a portion of a folded portion 8 of an electrostatic filter material 7 processed into a pleated shape and removing a portion of the folded portion. In this way, by cutting and removing a portion that is less effective in reducing pressure loss, a reduction in pressure loss is achieved, and the reduction in dust collection performance due to the provision of the cutting portion 9 is small.
