Abstract

An air conditioner capable of efficiently collecting foreign substances in the air is disclosed. The air conditioner includes a cabinet, an air blower disposed in the cabinet to cause air to flow, a dust collector case forming a channel for the air caused to flow by the air blower, at least one electrode provided in the dust collector case and formed of carbon fibers to generate ions, and a charged dust collecting filter to collect foreign substances charged by ions generated by the electrode.

First claim

The invention claimed is:

1. An air conditioner comprising:
a cabinet;
an air blower disposed in the cabinet to cause air to flow;
a dust collector case forming a channel for the air caused to flow by the air blower;
at least one electrode provided in the dust collector case and formed of carbon fibers to generate ions;
a charged dust collecting filter to collect foreign substances charged by ions generated by the electrode; and
a grounded ion trap to collect the ions generated by the electrode.

2. The air conditioner according to claim 1 , wherein the electrode is formed of superfine carbon fibers bound in a brush shape.

3. The air conditioner according to claim 1 , wherein the electrode is disposed at an inner wall of the dust collector case.

4. The air conditioner according to claim 3 , wherein the dust collector case has a quadrangular cross section,
wherein the at least one electrode includes four electrodes disposed at each of four corners of the dust collector case.

5. The air conditioner according to claim 1 , wherein the at least one electrode includes a plurality of electrodes disposed spaced from each other in an imaginary plane perpendicular to an air flow direction.

6. The air conditioner according to claim 1 , further comprising a heat exchanger to cause heat to be exchanged between the air caused to flow by the air blower and a refrigerant, the heat exchanger being grounded to collect the ions generated by the electrode.

7. The air conditioner according to claim 1 , wherein the dust collector case is partitioned into a plurality of sections,
wherein the electrode is disposed in one of the sections of the dust collector case.

8. The air conditioner according to claim 7 , further comprising:
a sterilization filter disposed in another one of the sections of the dust collector case; and
a deodorization filter disposed in a further one of the sections of the dust collector case.

9. The air conditioner according to claim 1 , further comprising a suction panel provided with an air suction portion, the air caused to flow by the air blower being suctioned into the air suction portion,
wherein the dust collector case is coupled to the suction panel.

10. The air conditioner according to claim 9 , wherein a cross section of the dust collector case is formed to correspond to the suction panel.

11. The air conditioner according to claim 9 , wherein the dust collector case is removable together with the panel from the cabinet.

12. An air conditioner comprising:
a cabinet;
an air blower disposed in the cabinet to cause air to flow;
a dust collector case forming a channel for the air caused to flow by the air blower;
an electrode provided in the dust collector case and allowing a current of a high voltage to be applied thereto, the electrode being formed of a carbon fiber;
a charged dust collecting filter disposed at a rear side of the electrode in the dust collector case; and
an ion trap disposed at a rear side of the dust collecting filter and configured with a grounded metallic member.

13. The air conditioner according to claim 12 , further comprising a heat exchanger disposed at a rear side of the dust collecting filter to cause heat to be exchanged between the air caused to flow by the air blower and a refrigerant.

14. An air conditioner comprising:
a cabinet;
an air blower disposed in the cabinet to cause air to flow;
a dust collector case forming a channel for the air caused to flow by the air blower;
an electrode provided in the dust collector case and allowing a current of a high voltage to be applied thereto, the electrode being formed of a carbon fiber;
a charged dust collecting filter disposed at a rear side of the electrode in the dust collector case; and
an ion trap disposed between the electrode and the dust collecting filter and configured with a grounded metallic member.
