Abstract

Disclosed is a filter device for air conditioning in which pressure loss is low and dust collection efficiency is high. In the filter device for air conditioning installed in an air-conditioning duct, the filter device for air conditioning includes: a case; an electrical dust collection unit provided inside the case; at least one filter unit provided so as to make contact with the electrical dust collection unit; and a guide unit provided such that the electrical dust collection unit and the filter unit can be detachably installed.

First claim

The invention claimed is:

1. A filter device for air conditioning installed in an air conditioning duct, the filter device comprising: a case; an electric dust collection unit provided inside the case; at least one filter unit adjacent to the electric dust collection unit; and a guide configured to receive the electric dust collection unit and the at least one filter unit wherein the electric dust collection unit and the at least one filter unit are removable, and wherein the guide includes a separation prevention member that is elastically deformable in a direction away from the at least one filter unit and is bent to support a side end of the at least one filter unit and to prevent the at least one filter unit from being separated from the case.

2. The filter device according to claim 1 , wherein the guide comprises an electrode portion configured to connect to the electric dust collection unit and at least one filter installation portion configured to receive the at least one filter unit.

3. The filter device according to claim 1 , wherein the at least one the filter unit includes at least one of a dust collection filter, a free filter, a high-efficiency particulate air (HEPA) filter, and an auxiliary filter.

4. The filter device according to claim 2 , wherein the case includes an opening formed at a side, a door configured to open and close the opening, and a fastener configured to fasten the door to the case.

5. The filter device according to claim 4 , wherein the case further includes a switch connected to the electrode portion, and wherein the door includes a switch pressing portion provided at an assembly point of the door and the switch pressing portion is configured to turn the switch on or off.

6. The filter device according to claim 1 , wherein the case further includes an edge portion that is on an external surface of the case and configured to support the case in series or parallel with respect to the air conditioning duct.

7. The filter device according to claim 6 , wherein the edge portion includes at least one fastening hole formed such that a fastening member is assembled.

8. The filter device according to claim 3 , wherein the auxiliary filter includes a filter including a deodorizing, an antibacterial, a germicidal and a special air purification functions in addition to dust collecting.

9. A filter device for air conditioning, comprising: a case; an electric dust collection unit provided inside the case; at least one filter unit adjacent to the electric dust collection unit; and a guide configured to receive the electric dust collection unit and the at least one filter unit wherein the electric dust collection unit and the at least one filter unit are removable, wherein the guide includes an electrode portion configured to connect to the electric dust collection unit and at least one filter installation portion configured to receive the at least one filter unit, and wherein the guide includes a separation prevention member that is elastically deformable in a direction away from the at least one filter unit and is bent to support a side end of the at least one filter unit and to prevent the at least one filter unit from being separated from the case.

10. The filter device according to claim 9 , wherein each of the at least one filter unit includes a dust collection filter, a free filter, or a high-efficiency particulate air (HEPA) filter.

11. The filter device according to claim 10 , wherein the at least one filter unit includes a stopper that is configured to prevent the at least one filter unit from separating, wherein the stopper is elastically deformable and positioned in at least one filter installation portion.

12. The filter device according to claim 9 , wherein the case includes an edge portion that is on an external surface of the case and configured to support the case in series or parallel.

13. The filter device according to claim 9 , wherein the case includes an opening formed at a side, a door configured to open and close the opening, and a fastener configured to fasten the door to the case.

14. The filter device according to claim 13 , wherein the case further includes a switch connected to the electrode portion, and wherein the door includes a switch pressing portion provided at an assembly point of the door and the switch pressing portion is configured to turn the switch on or off.
