Abstract

An air cleaner is provided that may include a cylindrical case including an inlet through which air is suctioned in a radial direction into the cylindrical case; a filter configured to be detachably provided in the case and having a cylindrical shape; and a filter frame configured to support the filter. The filter frame may include a lower frame provided at a lower portion of the filter; an upper frame provided at an upper portion of the filter; and a plurality of supporting frames that extends toward the upper frame from the lower frame. An entry portion for the suctioned air may be formed between the plurality of support frames, the entry portion being configured to receive the filter.

Claims

1. An air cleaner, comprising:

a cylindrical case including an inlet through which air is suctioned in a radial direction into the cylindrical case;

a filter configured to be detachably provided in the case and having a cylindrical shape; and

a filter frame configured to support the filter, wherein the filter frame includes;

a lower frame provided at a lower portion of the filter;

an upper frame provided at an upper portion of the filter; and

a plurality of supporting frames that extends toward the upper frame from the lower frame, wherein an entry portion for the suctioned air is formed between the plurality of support frames, the entry portion being configured to receive the filter.

2. The air cleaner of claim 1, wherein the plurality of supporting frames is arrayed in a circumferential direction.

3. The air cleaner of claim 2, wherein the plurality of supporting frames includes:

two first frames; and

at least one second frame provided in a space between the two first frames.

4. The air cleaner of claim 3, wherein the space includes a front portion and a rear portion, and the entry portion forms a front portion of the space.

5. The air cleaner of claim 4, wherein the second frame is provided in the rear portion of the space.

6. The air cleaner of claim 3, wherein a length of the first frame in a circumferential direction is longer than a length of the second frame.

7. The air cleaner of claim 3, wherein the first frame or the second frame may include an air flow guide that guides the air suctioned through the suction inlet to the filter.

8. The air cleaner of claim 7, wherein the air flow guide includes a slit.

9. The air cleaner of claim 3, wherein the two first frames and the second frame support an outer circumferential surface of the filter.

10. The air cleaner of claim 3, wherein the first frame includes:

a flat surface configured to guide a mounting of the filter; and

a curved surface configured to extend toward the second frame from the flat surface in a rounded shape and to support the filter.

11. The air cleaner of claim 3, wherein the at least one second frame includes a plurality of second frames.

12. The air cleaner of claim 1, further including:

a frame cover coupled with an exterior of the plurality of supporting frames; and

a wire space formed between the plurality of supporting frames and the frame cover and configured to receive therein a wire.

13. The air cleaner of claim 1, further including a support provided inside of the lower frame to support a lower side of the filter, wherein the plurality of supporting frames is arrayed along a perimeter of the support.

14. The air cleaner of claim 13, further including a handle at a lower side of the support, the handle being configured to be manipulated to move the filter in an upward or downward direction.

15. The air cleaner of claim 14, wherein the filter moves in the upward direction to be mounted in a mounting space inside of the filter frame when the handle rotates in a first direction, wherein the filter moves in the downward direction to be at a location at which the filter is detachable from the mounting space when the handle rotates in a second direction.

16. An air cleaner, including:

a case including a suction inlet to suction air in a radial direction;

a filter detachably provided in the case;

a fan provided at an outlet side of the filter;

a lower frame provided at a lower portion of the filter;

an upper frame provided at an upper portion of the filter; and

a plurality of supporting frames that extends toward the upper frame from the lower frame and arrayed in a circumferential direction, wherein the lower frame, the upper frame, and the plurality of supporting frames form a mounting space for the filter, wherein the filter moves toward the mounting space in the radial direction to be mounted therein, and wherein the case surrounds the plurality of supporting frames.

17. The air cleaner of claim 16, wherein the case has a cylindrical shape, and where the suction inlet is formed in an outer circumference surface of the case to guide air suctioned in the radial direction.

18. The air cleaner of claim 16, wherein the plurality of supporting frames includes a plurality of first frames, and wherein an entry portion of the mounting space is formed at a front portion of the space between the plurality of first frames.

19. The air cleaner of claim 18, wherein the plurality of supporting frames includes a second frame which is provided at a rear portion of the space between the plurality of first frames.

20. The air cleaner of claim 19, further including a fan housing that receives the fan, wherein the upper frame supports the fan housing.
