Definitions

  • the following description relates to a vacuum cleaner, and more particularly, to a turbine brush unit for rotating a brush and a vacuum cleaner having the same.
  • a vacuum cleaner in general, may include a brush member that comes in contact with a surface to be cleaned and cleans dust on the surface to be cleaned.
  • the brush member may scratch or bump the surface to be cleaned by a rotation force while moving along the surface to be cleaned, so that the dust on the surface to be cleaned is separated from the surface to be cleaned.
  • the dust separated from the surface to be cleaned by the brush member is drawn into a main body by a suction force generated from the main body.
  • the brush member may be configured to be rotated by a drive motor or to be rotated by air drawn through a suction portion. Also, the brush member may generally be configured to be rotated by inlet wind for the purpose of simplifying the configuration and saving cost.
  • FIG. 1 is a perspective view of a related art vacuum cleaner 1 having a turbine brush unit 100, a hose 200 and a main body 300.
  • FIG. 2 is a sectional view of the turbine brush unit 100 of FIG. 1 .
  • the turbine brush unit includes a turbine brush case 101, a brush member 102 mounted in the turbine brush case 101, and a turbine fan unit 110.
  • the turbine fan unit 110 includes an inlet duct 103, an outlet duct 104 and a fan member 110a disposed between the inlet and outlet ducts 103 and 104.
  • the turbine fan unit 110 is configured so that rotative power is provided to the brush member 102 by a belt (not shown).
  • the fan member 110a has a plurality of wings 112 and a rotating plate 111 having the plurality of wings 112 radially disposed thereon.
  • Primary inlet air a1 sucked through an inlet port collides with the wings 112, so that the fan member 110a is rotated in a rotation direction D.
  • the primary inlet air a1 may not collide with the wings 112 but form secondary reverse-current air a2 in the region of a fan member mounting portion P, in which the inlet and outlet ducts 103 and 104 are formed. Therefore, the secondary reverse-current air a2 is drawn into the fan member 110a.
  • the secondary reverse-current air a2 collides with the rear surface (the opposite surface to the surface facing the inlet port 103a) of each of the wings 112, and therefore, a frictional force is generated with respect to the rotation direction D.
  • the rotation force of the fan member 110a is decreased.
  • the decrease in the rotation force of the fan member 110a results in a decrease in the rotation force of the brush member 102. Therefore, cleaning may not be smoothly performed with respect to a surface to be cleaned, and loss of pressure may be increased.
  • EPO 338 780 discloses a turbine unit having a brush case, a brush member mounted in the turbine brush case, and a turbine fan unit comprising a plurality of wings and configured to rotate the brush member, each of the wings comprising a curvature point, primary and secondary collision surfaces against which corresponding inlet winds drawn down through an inlet portion of the turbine fan and collide, wherein the primary and secondary inlet winds apply a force in a rotation direction of the turbine fan unit.
  • a turbine brush unit for a vacuum cleaner including a turbine brush case, a brush member mounted in the turbine brush case, and a turbine fan unit having a plurality of wings and rotating the brush member.
  • Each of the plurality of the wings has a curvature point, a primary collision surface with which a primary inlet wind drawn through the inlet portion of the turbine fan unit collides and a secondary collision surface with which a secondary inlet wind collides, and the primary and secondary inlet winds apply a force in a rotation direction of the turbine fan unit.
  • the angle at which the primary inlet wind collides with each of the plurality of wings may be substantially 90 degrees or less.
  • Each of the plurality of wings may have an included angle of substantially 100 degrees or less, which is an angle made by two lines passing between the curvature point and ends of the wing.
  • Each of the plurality of wings may be formed in a U shape.
  • Each of the plurality of wings may be formed in a V shape.
  • a vacuum cleaner including a main body and a turbine brush unit, the turbine brush unit including a turbine brush case, a brush member mounted in the turbine brush case, and a turbine fan unit having a plurality of wings and rotating the brush member.
  • Each of the plurality of the wings has a curvature point, a primary collision surface with which a primary inlet wind drawn through the inlet portion of the turbine fan unit collides and a secondary collision surface with which a secondary inlet wind collides, and the primary and secondary inlet winds apply a force in a rotation direction of the turbine fan unit.
  • the primary collision surface and the secondary collision surface may be positioned at an angle relative to one another.
  • the angle may be smaller than 100 degrees.
  • the angle may be smaller than 90 degrees.
  • An angle may be formed by two lines which pass through the curvature point which is positioned on respective wings at a center point between the primary and secondary collision surfaces, and the angle is less than 100 degrees.
  • the angle may be less than 90 degrees.
  • a turbine brush unit of a vacuum cleaner including a turbine brush case, a brush member mounted in the turbine brush case, and a turbine fan unit having a plurality of wings and rotating the brush member.
  • Each of the plurality of the wings includes a primary collision surface and a secondary collision surface angled relative to the first collision surface, and a primary inlet wind drawn through the inlet portion of the turbine fan unit collides the primary collision surface and a secondary inlet wind collides with the secondary collision surface, and the primary and secondary inlet winds apply a force in a rotation direction of the turbine fan unit.
  • FIG. 3 illustrates an example of a first fan member 120a.
  • FIG. 4 illustrates an example of the structure of a first wing 122.
  • FIG. 5 illustrates an example of a turbine brush unit 100a illustrating the operational state of a first turbine fan unit 120 having the first fan member 120a.
  • the turbine brush unit 100a includes a turbine brush case 101, a first turbine fan unit 120 and a brush member 102.
  • the first turbine fan unit 120 includes a first fan member 120a provided with bent first wings 122 and a first rotating plate 121.
  • the first turbine fan unit 120 is mounted in a fan member mounting portion P formed by an outlet duct 104 and an inlet duct 103.
  • the first wing 122 may be formed in a V shape having a first inclined angle ⁇ 1 within a specific range about a first curvature point C1 at which a primary operating portion 122a and a secondary operating portion 122b intersect with each other.
  • the first included angle ⁇ 1 is an angle made by the first curvature point C1, the primary operating portion 122a and the secondary operating portion 122b.
  • first included angle ⁇ 1 made between the primary and secondary operating portions 122a and 122b, primary and secondary inlet winds A1 and A2, drawn into the interior of the first fan member 120a from a circumferential region of the first rotating plate 121, may collide with a primary or secondary collision surface 120a' or 120b' of each of the first wings 122, positioned opposite to the rotation direction of the rotating plate 121.
  • the first included angle ⁇ 1 may be an angle smaller than 100 degrees.

  • the primary and secondary inlet winds A1 and A2 drawn into the interior of the first fan member 120a may collide with the primary or secondary collision surface 120a' or 120b' of each of the first wings 122.
  • the primary and secondary inlet winds A1 and A2 drawn into the first rotating plate 121 may collide with the surfaces (the primary and secondary collision surfaces 120a' and 120b' in FIG. 5 ) of each of the first wings 122, which face an inlet port 103a, due to the V shape of the first wings 122.
  • the primary and secondary inlet winds A1 and A2 may avoid colliding with the rear surfaces (the opposite surface of the primary and secondary collision surface 120a' or 120b' in FIG. 5 ) of each of the wings 122.
  • a secondary operating force B that rotates the first fan member 120a in the rotation direction D may be additionally formed, and thus, the rotation force of the first fan member 120 may be increased. Since the secondary inlet wind A2 may avoid colliding with the surface (the opposite surface of the primary or secondary collision surface 120a' or 120b') of each of the wings 122 in the rotation direction D, the friction with the flow of air, caused by the first wings 122, may be minimized, and thus, the loss of pressure may be reduced.
  • the first wings 122 in one example, may be disposed so that the center line passing the first curvature point C1 is parallel with the tangent line of the first rotating plate 121.
  • this example is non-limiting, and it is unnecessary that the center line is parallel with the tangent line.
  • other suitable configurations may be employed.

  • the RPM of the first fan member 120a having the V-shaped first wings 122 arranged similar to the examples shown in FIGS. 3 to 5 showed 4200 RPM in load and 5700 RPM in unload. Accordingly, it can be seen that the rotation speed may be increased.
  • the RPM of the fan member 110a having the wings 112 of the related art showed 3900 RPM in load and 5200 RPM in unload.
  • the RPM of the first fan member 120a having the V-shaped first wings 122 arranged similar to the examples shown in FIGS. 3 to 5 showed 4300 RPM in load and 5700 RPM in unload.

  • the secondary inlet wind A2 drawn into a fan member mounting portion P along the circumference of the second fan member 130a may collide with the secondary collision surface 130b' of the secondary operating portion 132b, thereby generating a secondary operating force B.
  • the RPM of the second fan member 130a having the U-shaped second wings 132 of FIGS. 6 to 8 was compared with the RPM of the fan member 110a having the wings 112 of the related art.

  • the RPM of the second fan member 130a having the U-shaped second wings 132 arranged as shown in the examples of FIGS. 6 to 8 showed 4200 RPM in load and 5700 RPM in unload. Accordingly, it can be seen that the rotation speed may be increased.
  • inlet wind sucked into the interior of a fan member from the outer circumference of the fan member may collide with a plurality of wings so that an operating force is applied to the rotation direction of the fan member, and may thereby increase the rotation force of the fan member.
