What is claimed is: 1. A filter cleaning apparatus for cleaning a roll-type filter, the apparatus comprising: (i) a cleaning tank provided with a cavity for accommodating a cleaning solution; and (ii) a frame that is separable from the cleaning tank and comprises a supporting portion for supporting weight of the roll-type filter and a fixed portion protruding from the supporting portion for fixing the roll-type filter, wherein the supporting portion comprises a circular base having a plurality of through holes through which the cleaning solution passes, and a plurality of supporting members for partially supporting a lower portion of the roll-type filter, the supporting members are separated from each other in a radial direction relative to the center of the circular base and protrude from the top surface of the circular base toward the roll-type filter, and each of the supporting members extends in a circumferential direction of the roll-type filter, and the supporting members comprise at least one first supporting member extending along the circular base in a circumferential direction of the circular base and having a first radius from the center of the circular base, and at least one second supporting member extending along the circular base in a circumferential direction of the circular base and having a second radius from the center of the circular base, the second radius being larger than the first radius, wherein at least one of the through holes is disposed between the at least one first supporting member and the at least one second supporting member. 2. The filter cleaning apparatus of claim 1 , wherein the fixed portion of the frame is configured for insertion into a hollow shaft of a roll-type filter so as to fix the roll-type filter. 3. The filter cleaning apparatus of claim 1 , wherein the frame further comprises a handle portion which protrudes outside of the cleaning tank. 4. The filter cleaning apparatus of claim 1 , wherein a distance between the supporting members is approximately 5 mm to approximately 50 mm. 5. The filter cleaning apparatus of claim 1 , wherein a protruding height of the supporting members is approximately 5 mm to approximately 10 mm. 6. The filter cleaning apparatus of claim 1 , wherein a width of the supporting members is approximately 5 mm to approximately 10 mm. 7. The filter cleaning apparatus of claim 1 , wherein the supporting members are disposed along the circumferential direction of the circular base so as to be separated from each other. 8. The filter cleaning apparatus of claim 1 , wherein at least a portion of the frame is disposed within the cleaning tank, and at least one of the cleaning tank and the frame comprises a spacer so that a bottom surface of the cleaning tank and a lower surface of the supporting portion are separated from each other. 9. The filter cleaning apparatus of claim 1 , wherein the cleaning tank further comprises an outlet for discharging the cleaning solution. 10. The filter cleaning apparatus of claim 2 , wherein the fixed portion is detachably connected to the supporting portion. 11. The filter cleaning apparatus of claim 2 , wherein the fixed portion comprises an upper region and a lower region, wherein the upper region is further from the cleaning tank than the lower region, and the diameter of the upper region is smaller than the diameter of the lower region. 12. The filter cleaning apparatus of claim 3 , wherein the handle portion is detachably connected to the fixed portion. 13. The filter cleaning apparatus of claim 1 , further comprising a cover which is disposed above the cavity. 14. The filter cleaning apparatus of claim 13 , further comprising an elastic member having a ring shape which is disposed between the cover and the cleaning tank. 15. The filter cleaning apparatus of claim 13 , wherein the cover is provided with a hole for injecting the cleaning solution in at least a portion of an edge of the cover. 16. The filter cleaning apparatus of claim 15 , wherein the cover is provided with an opening and closing portion capable of obstructing the hole. 17. The filter cleaning apparatus of claim 15 , wherein the cover has an inclined portion which is sloped toward the hole.
