Abstract

An air conditioner that may include a case that forms an exterior thereof; a panel having an air inlet and disposed at one side of the case; an electric dust collector that collects foreign substances introduced through the air inlet; and a high voltage applying device electrically connected to the electric dust collector. The electric dust collector includes a discharge electrode that extends toward the air inlet and charges particles contained in air introduced through the air inlet, and an electrode holder that supports the discharge electrode so that an angle formed between an extension direction of the discharge electrode and a flow direction of air introduced through the air inlet may be changed, such that distribution of an ion field may be adjusted by adjusting the angle between the discharge electrode and the flow direction.

First claim

The invention claimed is:

1 . An air conditioner, comprising:
a case that forms an exterior of the air conditioner; a panel having an air inlet and disposed at one side of the case; an electric dust collector that collects foreign substances introduced through the air inlet; and a high voltage applying device electrically connected to the electric dust collector, wherein the electric dust collector includes:
a discharge electrode that extends toward the air inlet and charges particles contained in air introduced through the air inlet; and
an electrode holder that supports the discharge electrode so that an angle formed between an extension direction of the discharge electrode and a flow direction of air introduced through the air inlet is changeable, wherein the discharge electrode comprises:
a needle that receives a high voltage from the high voltage applying device; and
a pair of keys that supports the needle, wherein the pair of keys include a first key and a second key, wherein the first key and the second key have a same shape and extend in opposite directions, and wherein the needle is obliquely fixed to the electrode holder.

2 . The air conditioner according to claim 1 , wherein the discharge electrode obliquely extends outward from the panel.

3 . The air conditioner according to claim 1 , wherein the electrode holder is open toward the air inlet and has an electrode groove in which the discharge electrode is accommodated.

4 . The air conditioner according to claim 1 , wherein the electrode holder has a keyhole into which the discharge electrode is inserted.

5 . The air conditioner according to claim 1 , wherein the electrode holder has a valley formed in a direction crossing the extension direction of the discharge electrode.

6 . The air conditioner according to claim 1 , wherein the electrode holder comprises:
an electrode body in which the discharge electrode is accommodated; and a leg connected to an upper side of the electrode body.

7 . The air conditioner according to claim 6 , wherein the electrode holder includes a leg tip connected to an upper side of the leg.

8 . The air conditioner according to claim 6 , wherein the leg protrudes outward as the leg extends upward.

9 . The air conditioner according to claim 1 , wherein the electric dust collector includes an electrode cap that is connected to the electrode holder and supports the discharge electrode.

10 . The air conditioner according to claim 9 , wherein the electrode cap has a fence protruding outward from the electrode holder.

11 . The air conditioner according to claim 1 , wherein the electric dust collector includes a holder case in which the electrode holder is seated.

12 . The air conditioner according to claim 11 , wherein the electric dust collector comprises:
a dust collection unit that collects foreign substances introduced through the air inlet; and a seating frame that is disposed outside of the dust collecting unit and supports the holder case.

13 . The air conditioner according to claim 11 , wherein the holder case comprises:
a receiving body at least a portion of which protrudes toward the panel; and a support body connected to the receiving body.

14 . The air conditioner according to claim 11 , wherein the holder case has a crest inserted into a valley formed on one side of the electrode holder.
