Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a multi-stage ion wind air purifier that can obtain purified air by using the ion wind induced by corona discharge. It is.

[Background of the idea]

A conventional multi-stage ion air air cleaner of this type has a structure as shown in FIG. 2, for example. This multi-stage ionizing air purifier includes a plurality of ionized wires 1 in the first stage, and adjacent ionized wires 1 arranged on the exhaust port side of the ionized wires 1.
a plurality of auxiliary electrodes 2 disposed at substantially intermediate positions;
Second-stage ionization wires 3 supported near the edges of these auxiliary electrodes on the exhaust port side, and adjacent ionization wires 3 arranged closer to the exhaust port than these second-stage ionization wires 3. It has a plurality of dust collecting electrode plates 4 arranged at intermediate positions, and when a high voltage DC power supply 5 is turned on,
By applying a positive high voltage to the first stage ionization line 1, zero potential to the auxiliary electrode and second stage ionization line 3, and applying a negative high voltage to the dust collecting electrode plate 4, air due to positive ions is applied. The structure is such that the acceleration of the middle molecules is performed in two stages to improve the wind speed and pressure, thereby ensuring an air volume suitable for the indoor volume.

However, in such conventional multi-stage ion wind air purifiers, as mentioned above, the part that accelerates molecules in the air is multi-stage.
Although a high flow rate can be obtained, since the dust collection section has a single-stage structure with only the dust collection electrode plate 4, the dust suction in the dust collection section cannot keep up with the high flow rate, and as a result, the dust is transferred to the dust collection electrode plate. There was a problem in that effective clean air could not be obtained because the air was blown through the air.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems, and by providing the support plate that supports the second stage ionization wire with a dust collection function to enable two-stage dust collection, the wind speed can be reduced. It is an object of the present invention to provide an ionic wind air purifier that can improve the dust collection effect as well as improve the dust collection effect.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIG.

Reference numeral 11 denotes a first ionization wire support plate, and a first ionization wire 12 is stretched in parallel along the edge of the support plate 11 on the exhaust port side. Reference numeral 13 denotes a first dust collection electrode plate which also serves as a second ionization wire support plate, which is disposed closer to the exhaust port than the first ionization wire 12 and is spaced apart so as to sandwich the first ionization wire 12. So, this dust collector plate 1
A second ionization wire 14 is stretched parallel to the edge of the exhaust port 3 along the edge. That is, the first ionized wire 12 is arranged near the end edge 3a of the dust collecting electrode plate 13 on the intake port side, and furthermore, the first ionized wire 12 is arranged near the end edge 3a of the first dust collecting electrode plate 13 on the exhaust port side.
The intake port side portion 15a of the second dust collection electrode plate 15 is arranged to face the second dust collection electrode plate 15, and the second dust collection electrode plate 1 is arranged at the exhaust port side end edge 13c of the first dust collection electrode plate 13.
The second ionization line 14 is arranged opposite to the exhaust port side portion 15b of No. 5. Reference numeral 16 indicates a high-voltage DC power supply, which applies a positive potential to the first ionization wire 12 and its support plate 11, applies a zero potential to the first dust collection electrode plate 13 and the second ionization wire 14, and applies a zero potential to the first ionization wire 12 and its support plate 11.
The device is activated by applying a negative potential to the dust collecting electrode plate 15 of the device.

With such a configuration, ion wind is generated in two stages from the first ionization line 12 toward the second ionization line 14, and a desired air volume can be obtained. Further, the dust particles contained in this ionized wind are charged to a positive potential by the first ionized wire 12, and the first dust collection is carried out by the electric field between the first ionized wire 12 and the first dust collecting electrode plate 13. It is done.
Next, the ion wind is collected a second time by an electric field generated between the first dust collecting electrode plate 13 and the second dust collecting electrode plate 15. Next, a third dust collection is performed by the electric field generated by the second ionization wire 14 and the second dust collection electrode plate 15, and the dust contained in the ion wind is effectively collected and removed. It is something that will be done.

[Summary of the idea]

As described above, in the present invention, the first ionized wire 1 is provided near the edge 13a of the first dust collecting electrode plate 13 on the intake port side.
2, and the intake port side portion 15a of the second dust collecting electrode plate 15 is disposed substantially parallel to and opposite to the exhaust port side portion 13b of the first dust collecting electrode plate 13; A second ionization line 14 is disposed on the exhaust port side end edge 13c of the dust collecting electrode plate 13 facing the exhaust port side portion 15b of the second dust collecting electrode plate 15. This is an ionic air purifier.

[Effect of idea]

Therefore, according to this ionizing air purifier, the ionization section has a two-stage structure, and the dust collection section can also be configured in multiple stages of two or more stages. This has the effect of effectively removing dust contained in the ionized wind.
