  • the guide groove 115 is configured as a long groove formed at one side of the rotation supporting members 114 and 116, which support the worm wheels 134 and 136, on the brush body 110.
  • a pair of the guide grooves 115 are preferably disposed on both sides of the rotation supporting members 114 and 116, respectively.
  • the movement of the wet-cloth boards 151 and 152 is determined by relationships between the cam grooves 153 and 156 and the guide grooves 115 formed on the brush body 110. According to the wet-cloth brush 100 of the present embodiment, as shown in FIG.
  • the cam grooves 153 and 156 of the wet-cloth boards 151 and 152 are disposed perpendicularly to the rotation shafts 122 and 123 of the fan 120 whereas the guide grooves 115 of the brush body 110 are disposed parallel with the rotation shafts 122 and 123 of the fan 120, with respect to a length direction of the grooves. That is, the cam grooves 153 and 156 of the wet-cloth boards 151 and 152 are perpendicularly disposed to the guide grooves 115 of the brush body 110 with respect to the length directions of the grooves.
  • the wet-cloth brush 100 comprises a pair of the guide grooves 115 on both sides of the first and the second rotation supporting members 114 and 116 that support the first and the second worm wheels 134 and 136 of the brush body 110, respectively, and a pair of the guide projections 154 and 157 on the wet-cloth boards 151 and 152 to correspond to the guide grooves 115.
  • the guide projections 154 and 157 have at an upper part thereof escape-prevention members 155 and 158 fixed by a fastening member such as a bolt, respectively, to restrain the wet-cloth boards 151 and 152 from escaping from the guide grooves 115 of the brush body 110.
  • a plain washer having a diameter greater than a width of the guide groove 115 may be used for the escape-prevention members 155 and 158. Therefore, as the eccentric cams 141 and 142 are rotated by the worm wheels 134 and 136, the wet-cloth boards 151 and 152 can linearly reciprocate through the cam grooves 153 and 156 inserted with the eccentric cams 141 and 142 and the guide projections 154 and 157 inserted in the guide grooves 115, without being separated from the brush body 110.
  • a plurality of sticking seats 159 are provided to attach the wet-cloth (not shown).
  • first and the second wet-cloth boards 151 and 152 may be operated by the first and the second eccentric cams 141 and 142 independently, it is preferable that they are operated in association with each other. To enhance vibration reduction, the wet-cloth boards 151 and 152 may be symmetrically operated. For example, as the first wet-cloth board 151 moves toward a center part of the brush body 110, the second wet-cloth board 152 moves toward the center part at the same time, and as the first wet-cloth board 151 moves outward with respect to the brush body 110, so does the second wet-cloth board 152.
  • first and the second wet-cloth boards 151 and 152 reciprocate and repeatedly approach at the center part of the brush body 110 and then separate to outer parts of the brush body 110.
  • first and the second worm wheels 134 and 136 may rotate in opposite directions.
  • the first and the second eccentric cams 141 and 142 are disposed in the same direction, as shown in FIG. 6.
  • the first and the second wet-cloth boards 151 and 152 preferably have sloping edges 151a and 152a facing each other, respectively.
  • the sloping edges 151a and 152a provide a beveled edge for wet-cloth boards 151 and 152, extending between bottom surfaces 151c and 152c attached to the wet-cloth and upper surfaces 151d and 152d directly mounted to the brush body 110.
  • the wet-cloth boards 151 and 152 are sized to allow the wet-cloth boards 151 and 152 to be partly exposed and viewed by a user from above the brush body 110. Therefore, the user can check the operation of the wet-cloth boards 151 and 152 while operating the vacuum cleaner.
  • both corners 113 of a side of the brush body 110, the side connected to the pipe 221, are rounded while the first and the second wet-cloth boards 151 and 152 are formed in a generally rectangular shape. Accordingly, one corner of the respective wet-cloth boards 151 and 152 can always be viewed through the rounded corners 113 of the brush body 110.
  • flank sides 151b and 152b of the wet-cloth boards 151 and 152 are visible, by protruding from the brush body 110, when the both wet-cloth boards 151 and 152 are moved to the outermost limit, as shown in FIG. 8.
  • first and the second eccentric cams 141 and 142 integrally formed with a lower part of the worm wheels 134 and 136 are rotated at a certain distance from the rotational centers of the first and the second worm wheels 134 and 136, as shown in FIG 6. Because the first worm gear 133 and worm wheel 134 and the second worm gear 135 and worm wheel 136 rotate in opposite directions, if the first worm wheel 134 rotates clockwise, for example, the second worm wheel 136 rotates counterclockwise.
  • the first and the second eccentric cams 141 and 142 rotate, the first and the second wet-cloth boards 151 and 152 linearly reciprocate in a length direction of the brush body 110 by the cam grooves 153 and 156 which hold the first and the second eccentric cams 141 and 142 and the guide projections 154 and 157 inserted in the guide grooves 115 of the brush body 110.
  • the first and the second eccentric cams 141 and 142 are symmetrically disposed and rotated in the opposite directions, as shown in FIG 6, the first and the second wet-cloth boards 151 and 152 also symmetrically reciprocate by rotation of the fan 120.
  • FIGS. 8A to 8C show the operation of the first and the second wet-cloth boards 151 and 152. More specifically, FIG. 8A shows the first and the second wet-cloth boards 151 and 152 moved to the outermost limit by rotation of the first and the second eccentric cams 141 and 142. FIG. 8B shows the wet-cloth boards 151 and 152 in motion toward the center part of the brush body 110, and FIG. 8C show the wet-cloth boards 151 and 152 at their closest approach to the center part of the brush body 110.
  • flank sides 151b and 152b of the wet-cloth boards 151 and 152 extend partially beyond brush body 110 when the wet-cloth boards 151 and 152 are at their outermost limit. Therefore, the user can visually verify operation of the wet-cloth boards 151 and 152 merely by looking down.
  • first and the second wet-cloth boards 151 and 152 respectively have sloping sides 151a and 152a facing each other, as shown in FIG. 7. Therefore, fingers and other items will not be pinched by the wet-cloth boards 151 and 152 as wet-cloth boards 151 and 152 move toward the center.
  • FIG. 9 shows the operation of a vacuum cleaner applying the wet-cloth brush 100 according to another embodiment of the present invention.
  • a vacuum cleaner 200 according to an embodiment of the present invention comprises a wet-cloth brush 110 for drawing in dust-laden air, the extension pipe 220 fluidly connecting the wet-cloth brush 100 with a cleaner body 230, and the cleaner body 230 including a dust collecting chamber 235 and a motor chamber 231.
