Abstract

PURPOSE:To obtain an electrode generating no spark while dispensing with an earth electrode, by forming a large number of anion generating needles by punching a metal plate in a special form to use them as cathodes. CONSTITUTION:Anion generating needles 7 are formed by punching a metal plate 6 and alternately bending the punched parts to the front and back sides of said metal plate 6 while anion generating needles 8 provided to the upper and lower edges as well as the left and right edges of said metal plate 6 are formed by a punching mold. A minus high voltage power source is connected to thus formed cathodes through lead wires and a flat plate or a punched partition plate comprising a metal, a resin or paper is combined therewith to make it possible to efficiently generate a large amount of anions in an air purifier and purification efficiency of air is enhanced.

Description

[Detailed description of the invention] A conventional dust collection electrode is made up of a combination of an electrode 1 that applies a high voltage and a ground electrode 2. In order to increase the dust collection efficiency at this m-pole part, the electrode 1 It is necessary to bring the intervals between the cells 2 closer together, or to apply a higher voltage from the high-voltage power supply 3, or to increase the current flowing therethrough.

However, increasing the dust collection efficiency in this way increases the amount of ozone generated, and also has the disadvantage that sparks sometimes occur between the high voltage electrode and the ground electrode.

On the other hand, the device of the present invention does not use a ground electrode, so it does not generate any ozone, and it can generate large amounts of anions, which are called the vitamins of the air, without worrying about sparks.

This can be illustrated in FIG. 2, in which a negative high voltage from a negative high voltage power source 3 is connected to an electrode 6 by a lead wire 4.

In this way, an ion flow of anions is generated from the anion generation needles 7 and 8, and this ion flow has the power to extinguish smoke from cigarettes and the like.

Therefore, this electrode 6 alone has a dust collection effect, but when used in a wider area, several 111i6 electrodes are used and a partition plate 9 is used between them.

As the partition plate 9, a flat plate of metal, resin, paper, or punching is used.

The combination use with this partition plate 9 is determined by the size of the place where the air purifier is used and the size of the negative high voltage m source 3 applied to the electrode 6.

FIGS. 3 and 4 show the electrode portion, with FIG. 3 being a sectional view thereof, and FIG. 4 being a view showing the entire electrode.

The anion generating needle 7 is made by punching out a metal plate 6 and bending it back and forth alternately, and the top, bottom, left and right sides 8 are made by punching.

This electrode 6 effectively generates an ion flow in the front-rear, up-down, left-right directions, and is a non-directional anion generating electrode.

Since the partition plate 9 is not connected to the ground 5 and may be an insulator, no ozone is generated between the electrodes, and no sparks are generated.

In this way, the product of the present invention efficiently generates anions,
The ion flow cleans the air, and it is effective both without a fan or in combination with a fan.
