Definitions

  • the present invention relates to a suction brush for a vacuum cleaner. More particularly, the present invention relates to a suction brush for a vacuum cleaner with cloths.
  • a vacuum cleaner is an apparatus for sucking dust or contaminants on a cleaning surface using suction force generated by a suction motor when a suction brush is moved on the cleaning surface.
  • the vacuum cleaner can remove dust or/and contaminants scattered on a cleaning surface, but cannot effectively remove foreign bodies adhered on a cleaning surface and/or stains on a cleaning surface. At this time, after removing dust on a floor of a room using the vacuum cleaner, users should scrub the floor using a cloth in order to remove adhered foreign bodies or stains remaining on the cleaning surface. Thus, many users feel that it is inconvenient to clean with the conventional vacuum cleaner.
  • the cloth rotating structure includes a turbine fan rotated by sucked outside air, a power transmitting unit for transmitting a rotation power of the turbine fan to opposite sides of an under part of the suction brush with a plurality of driving shafts and spur gears, and a pair of cloth supporting parts to receive the rotation power of the turbine fan via the power transmitting unit so as to rotate the cloths.
  • the conventional turbine fan is rotated by the indirect driving method using suction force by the suction motor, to increase the rotation speed and rotation torque of the cloth is limited compared to the direct driving method that a motor is directly connected to the cloth supporting part to rotate the cloth. Therefore, when a cleaning surface is a little rough, the conventional suction brush cannot smoothly rotate the cloth so that a cleaning work is not effectively performed.
  • An aspect of the present invention is to provide a suction brush for a vacuum cleaner, which can prevent thin, long foreign bodies with relatively rigidity from entering a suction pathway.
  • Another aspect of the present invention is to provide a suction brush for a vacuum cleaner, capable of increasing the rotation speed of a turbine fan.
  • a suction brush for a vacuum cleaner which includes a cleaning member for cleaning a cleaning surface, a suction port and a dust guiding groove for guiding contaminants-laden air to the suction port to be formed at a bottom surface of the suction brush, and a turbine fan driven by suction force of a suction motor for rotating the cleaning member.
  • the suction brush comprises a catching part disposed apart from the suction port in a place corresponding to the suction port inside the dust guiding groove for reducing a space around the suction port, wherein the catching part prevents rigid, thin, and long foreign bodies from entering the suction pathway.
  • the catching part is wider than the width of the suction port, and a bottom end of the catching part is formed at a lower level than a bottom end of the suction port.
  • Both sides of the catching part are inclined in a direction of the suction port.
  • a bottom surface of the catching part is inclined in a direction of the suction port.
  • the turbine fan comprises a pair of supporting discs; and a plurality of wings disposed between the pair of supporting discs, one end of each of the wings is fixed to anyone of the pair of supporting discs, the other end of each of the wings alternating with to overlap each other.
  • the suction brush further comprises a partition wall formed along the length of the suction pathway inside the suction pathway in order to divide the suction pathway into a plurality of pathways.
  • a suction brush for a vacuum cleaner comprises: a body having a suction port, a dust guiding groove guiding contaminants-laden air to the suction port, and a suction pathway guiding the contaminants-laden air entering through the suction port to a dust collecting apparatus; a turbine fan rotatably disposed at the suction pathway of the body; a cover covering an upper side of the body so as to the form the suction pathway; a partition wall formed along the length of the suction pathway inside the suction pathway in order to divide the suction pathway into a plurality of pathways; a pair of cloth supporting plates rotatably disposed on a bottom surface of the body for detachably mounting a cloth on a bottom surface of each of the cloth supporting plates; a power transmitting unit disposed in the body, the power transmitting unit transmitting the rotation power of the turbine fan to the pair of cloth supporting plates for rotating the pair of cloth supporting plates; and a catching part projected inside the dust guiding groove to face the suction port a pre
  • the turbine fan has a plurality of wings disposed between a pair of supporting discs, one end of each of the plurality of wings alternating to overlap each other.
  • a distance between the suction port and the front surface of the catching part facing the suction port is approximately 12.5 mm to 14.5 mm.
  • the suction brush for the vacuum cleaner according to an embodiment of the present invention, because rigid, thin, and long foreign bodies are prevented from entering the suction pathway through the suction port, the suction brush may prevent the entered foreign body from stopping the rotation of the turbine fan or from damaging the wings of the turbine fan.
  • the area of the plurality of wings of the turbine fan is increased for receiving more power of air sucking through the suction pathway so that the rotation speed and the rotation torque of the turbine fan are increased. Therefore, the rotation speed of the cloth is increased so that the cleaning efficiency with respect to a cleaning surface is increased.
  • the width of the suction pathway becomes narrower than the width of the conventional suction pathway due to the partition wall so that rigid, thin, and long foreign bodies entering the suction pathway becomes roughly parallel to the suction pathway.

  • the body 11 has at a bottom surface thereof a suction port 62 a and 62 b (see FIG. 5 ) and a dust guiding groove 15 for guiding dust and/or contaminants on a cleaning surface with air (hereinafter, referred to as contaminants-laden air) to the suction port 62 a and 62 b .
  • the body 11 further comprises a suction pathway 61 a and 61 b (see FIG. 6 ) for guiding dust and air entering the suction port 62 a and 62 b to a dust collecting apparatus (not shown).
  • a connecting pipe 23 being in fluid communication with the flexible hose (not shown) and a necking part 21 wrapping around a part of the turbine fan 30 are disposed at a backside of the body 11 .
  • the turbine fan 30 is disposed at the suction pathway 61 a and 61 b , and has a pair of supporting discs 31 a and 31 b and a plurality of wings 33 a and 33 b disposed between the pair of supporting discs 31 a and 31 b as shown in FIGS. 3 and 4 .
  • One end of each of the plurality of wings 33 a and 33 b is fixed to anyone of the pair of supporting discs 31 a and 31 b , and the other end 34 a and 34 b thereof is free.
  • the plurality of wings 33 a and 33 b is arranged such that the wings 33 a fixed to one supporting disc 31 a are placed between the wings 33 b fixed to the other supporting disc 31 b as shown in FIG. 4 .
  • free ends 34 a of the wings 33 a fixed to one supporting disc 31 a alternate with of free ends 34 b the wings 33 b fixed to the other supporting disc 31 b .
  • free ends 34 a of the wings 33 a fixed to one supporting disc 31 a are not extended to touch the other supporting disc 31 b.
  • the free ends 34 a and 34 b of the plurality of wings 33 a and 33 b is formed to overlap each other, the total area of the plurality of wings 33 a and 33 b is increased as much as the overlapping area of the plurality of wings 33 a and 33 b compared with the conventional turbine fan. Therefore, the plurality of wings 33 a and 33 b receives more force as much as the increased overlapping area of the plurality of wings 33 a and 33 b by air that is sucked in the suction pathway 61 a and 61 b along a direction of arrow B of FIG. 3 indicated from the outside of the suction brush 10 to the inside thereof so that the rotation speed of the turbine fan 30 is increased.
  • the increase of the rotation speed of the turbine fan 30 causes the rotation speed of the cloth 49 to increase so that the cleaning efficiency with respect to a cleaning surface is increased.
