Document Type and Number:
Japanese Patent JPH07505312
Kind Code:
A
Abstract:
The improved carpet cleaning machine, intended for use with "dry" carpet cleaning systems using dampened granules or particles, can be used in either of two modes. One involves carpet "brushing" for dirt removal by urging particles into the carpet and along the fibers. The other involves later vacuuming for particle removal. To facilitate the latter, one embodiment of the machine has first and second particle-removing media such as a concentrically-mounted cyclone separator and conical screen filter, respectively. The separator has air flowing through it downwardly along a vortical path and then upward, such air flow often carrying along a few particles. Such high-velocity particles impinge on the outer surface of the screen filter and many particles adhering to such filter are dislodged. The filter is said to thereby be "purged" or cleaned. There may also be a third medium and even a fourth medium to remove very fine particles before the air is expelled back into the room. Other embodiments use an automotive, resilient foam or flat-element filter medium in place of or in addition to the conical screen filter.
