Abstract

A plasma electrode device, a method of manufacturing plasma electrode device, and an air conditioner are provided. The plasma discharge device may include an insulating body; a discharge electrode formed in a first surface of the insulating body to generate plasma discharge; and a ground electrode formed in a second surface of the insulating body to generate plasma discharge by reacting with the discharge electrode. The discharge electrode may have a prescribed pattern having a plurality of branches, and the insulating body may include a flexible material configured to be curved at a predetermined curvature.

First claim

What is claimed is:

1. An air conditioner comprising:
a main body having an air inlet through which air is suctioned into the main body and an air outlet through which air suctioned in through the air inlet is discharged from the main body after being conditioned;
a fan provided in the main body to cause air to flow;
a discharge vane configured to guide air discharged from the air outlet and formed such that an inner surface facing an inside of the main body is curved; and
a plasma electrode device provided in a path of air flow generated by the fan to generate a large amount of ions, wherein the plasma electrode device includes:
an insulating body;
a discharge electrode formed in a first surface of the insulating body to generate plasma discharge; and
a ground electrode formed in a second surface of the insulating body to generate plasma discharge by reacting with the discharge electrode, wherein the discharge electrode includes a prescribed pattern having a plurality of branches, and wherein the insulating body includes a flexible material configured to be curved at a predetermined curvature, wherein the plasma electrode device is mounted on the inner surface of the discharge vane and is curved corresponding to a shape of the inner surface of the discharge vane.

2. The air conditioner of claim 1 , wherein the insulating body has a thickness of dozens of micrometers.

3. The air conditioner of claim 1 , wherein the insulating body includes polyimide resin.

4. The air conditioner of claim 1 , wherein the plurality of branches of the discharge electrode has a width of dozens of micrometers.

5. The air conditioner of claim 1 , wherein the discharge electrode and the ground electrode are formed by depositing a metal plate on the insulating body and performing etching such that the discharge electrode has the prescribed pattern.

6. The air conditioner of claim 1 , wherein the prescribed pattern of the discharge electrode has a non-patterned portion in which no electrode is formed.

7. The air conditioner of claim 6 , wherein the non-patterned portion has a prescribed width between the plurality of branches such that the plurality of branches is arranged at uniform interval.
