Abstract

An air cleaning device is provided. The air cleaning device includes: a main body; a filter configured to be disposed in the main body to purify air; and an image transmitter configured to show a state of the filter to an outside of the main body.

First claim

What is claimed is:

1. An air cleaning device comprising:
a main body;
a filter configured to be disposed in the main body to purify air; and
an image transmitter configured to show a state of the filter to an outside of the main body,
wherein the image transmitter is a main mirror;
wherein the main mirror is disposed to incline toward a side of the filter so as to reflect a part of the filter;
wherein the main body comprises:
a check hole that is formed in a position into which an image reflected from the main mirror is projected for visual inspection,
an external mirror configured to be disposed to incline toward the check hole, and
a door that opens and closes the check hole; and

wherein the external mirror is attached onto the door.

2. The air cleaning device of claim 1 , wherein a transparent member is installed in the check hole.

3. The air cleaning device of claim 1 , wherein the main body comprises an internal blocking plate configured to block parts except the check hole that is exposed when the door is opened.

4. The air cleaning device of claim 1 , wherein the check hole is formed on one selected from a side, a front surface, and an upper surface.

5. An air cleaning device comprising:
a main body;
a filter configured to be disposed in the main body to purify air;
an image transmitter configured to show a state of the filter to an outside of the main body, wherein the image transmitter is a main mirror; and
an internal mirror configured to incline toward the main mirror or to be disposed parallel with the main mirror so as to re-reflect the image reflected from the main mirror for visual inspection,
wherein the main mirror inclines toward a side of the filter to reflect a part of the filter, and the main body further comprises:
a check hole that is formed in a position into which the image reflected from the internal mirror is projected,
an external mirror configured to be disposed to incline toward the check hole, and
a door that opens and closes the check hole; and

wherein the external mirror is attached onto the door.

6. The air cleaning device of claim 5 , wherein a transparent member is installed in the check hole.

7. The air cleaning device of claim 5 , wherein the check hole is formed on a front surface of the main body.

8. The air cleaning device of claim 1 , wherein the main mirror is rotatably installed to change the reflected part of the filter.

9. The air cleaning device of claim 1 , further comprising:
an illumination lamp configured to be disposed in the main body to illuminate the part of the filter reflected from the main mirror.

10. The air cleaning device of claim 1 , wherein the main body comprises a lighting hole that is formed in a position of the main body from which light outside of the main body is irradiated onto the part of the filter reflected from the main mirror.

11. An air cleaning device comprising:
a main body;
a filter configured to be disposed in the main body to purify air;
a check hole configured to penetrate the main body so as to show an internal part of the main body for visual inspection;
a door that opens and closes the check hole,
a main mirror configured to reflect a part of the filter; and
an external mirror configured to be disposed outside the main body to re-reflect an image of the part of the filter reflected from the main mirror or an internal mirror configured to be disposed inside the main body to re-reflect the image of the part of the filter reflected from the main mirror,
wherein the external mirror is attached onto the door.

12. The air cleaning device of claim 11 , wherein the main mirror rotates to adjust an angle.

13. The air cleaning device of claim 12 , wherein the rotation of the main mirror is manually controlled by a handle or automatically controlled by an electric motor in order to rotate the main mirror to enable a user to view different areas of the filter.

14. The air cleaning device of claim 8 , wherein the rotation of the main mirror is manually controlled by a handle or automatically controlled by an electric motor in order to rotate the main mirror to enable a user to view different areas of the filter.
