Abstract

Provided is an air conditioner having an ion generation device, the ion generation device including a main body including an electrode structure that includes a discharge electrode and a ground electrode, a coupling part disposed on at least one surface of the main body, the coupling part being coupled to the case, and an ion discharge part disposed on the main body to discharge the ions generated when a high voltage is applied to the electrode structure.

First claim

The invention claimed is:

1. An air conditioner comprising:
a case comprising a suction part;
a discharging part disposed in the case to discharge air suctioned through the suction part;
a discharge vane disposed at a side of the discharge part, the discharge vane being motionably provided to open or close the discharge part; and
an ion generation device disposed within the discharging part to generate ions, wherein the ion generation device comprises:
a main body comprising an electrode structure;
a coupling part disposed on at least one surface of the main body, the coupling part being coupled to the case; and
an ion discharge part disposed on the main body to discharge the ions generated when a high voltage is applied to the electrode structure, wherein the electrode structure comprises:
a ceramic substrate;
a discharge electrode disposed on a first surface of the ceramic substrate, the discharge electrode comprising a discharge electrode part and at least one discharge tip; and
a ground electrode disposed on a second surface of the ceramic substrate, the ground electrode comprising a ground electrode part,
wherein the discharge electrode comprises a pattern frame on which a plurality of diagrams are disposed,
the pattern frame comprises an external diagram and an internal diagram disposed within the external diagram and not in contact with the external diagram, and
each of the external and internal diagrams provided in a closed configuration and includes at least one a discharge tip.

2. The air conditioner according to claim 1 , wherein the ion generation device is covered with respect to ambient in a state where the discharge vane is closed and wherein the ion generation device is opened with respect to the ambient in a state where the discharge vane is opened.

3. The air conditioner according to claim 1 , wherein the ion generation device may be a plurality of ion generation devices provided within the discharging part.

4. The air conditioner according to claim 1 , wherein the ions comprise negative and positive ions generated by ionizing neutral molecules within air, and the negative and positive ions are combined with moisture of the air to bind and to form water ion clusters.

5. The air conditioner according to claim 1 , wherein the external diagram and the internal diagram may be disposed so that they do not overlap each other.

6. The air conditioner according to claim 1 , wherein the external diagram and the internal diagram have the same shape.

7. The air conditioner according to claim 1 , wherein the discharge electrode comprises a discharge obstacle disposed between the external diagram and the internal diagram to interrupt discharge interference between the discharge tip of the external diagram and the discharge tip of the internal diagram.

8. The air conditioner according to claim 1 ,
wherein a ratio of the number of discharge tips disposed on the external diagram to the number of discharge tips disposed on the internal diagram is 4 to 5.
