Abstract
Description
- 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 relatedart vacuum cleaner 1 having aturbine brush unit 100, ahose 200 and amain body 300.FIG. 2 is a sectional view of theturbine brush unit 100 ofFIG. 1 . - As shown in
FIG. 2 , the turbine brush unit includes aturbine brush case 101, abrush member 102 mounted in theturbine brush case 101, and aturbine fan unit 110. - The
turbine fan unit 110 includes aninlet duct 103, anoutlet duct 104 and afan member 110a disposed between the inlet andoutlet ducts turbine fan unit 110 is configured so that rotative power is provided to thebrush member 102 by a belt (not shown). - As shown in
FIG. 2 , thefan member 110a has a plurality ofwings 112 and a rotatingplate 111 having the plurality ofwings 112 radially disposed thereon. Primary inlet air a1 sucked through an inlet port collides with thewings 112, so that thefan member 110a is rotated in a rotation direction D. - However, in the related art vacuum cleaner, 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 andoutlet ducts fan member 110a. - As shown in
FIG. 2 , the secondary reverse-current air a2 collides with the rear surface (the opposite surface to the surface facing theinlet port 103a) of each of thewings 112, and therefore, a frictional force is generated with respect to the rotation direction D. As a result, the rotation force of thefan member 110a is decreased. The decrease in the rotation force of thefan member 110a results in a decrease in the rotation force of thebrush member 102. Therefore, cleaning may not be smoothly performed with respect to a surface to be cleaned, and loss of pressure may be increased. - In one general aspect, there is provided 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.
- In another aspect, there is provided 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.
- In still another aspect, there is provided a turbine brush unit of a vacuum cleaner, 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 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 afirst fan member 120a.FIG. 4 illustrates an example of the structure of afirst wing 122.FIG. 5 illustrates an example of aturbine brush unit 100a illustrating the operational state of a firstturbine fan unit 120 having thefirst fan member 120a. - Referring to
FIGS. 3 to 5 , for example, theturbine brush unit 100a includes aturbine brush case 101, a firstturbine fan unit 120 and abrush member 102. - Referring to the example in
FIG. 5 , the firstturbine fan unit 120 includes afirst fan member 120a provided with bentfirst wings 122 and a firstrotating plate 121. The firstturbine fan unit 120 is mounted in a fan member mounting portion P formed by anoutlet duct 104 and aninlet duct 103. - As shown in
FIG. 4 , thefirst wing 122 may be formed in a V shape having a first inclined angle θ1 within a specific range about a first curvature point C1 at which aprimary operating portion 122a and asecondary operating portion 122b intersect with each other. In the plurality offirst wings 122, the first included angle θ1 is an angle made by the first curvature point C1, theprimary operating portion 122a and thesecondary operating portion 122b. - Due to the first included angle θ1 made between the primary and
secondary operating portions first fan member 120a from a circumferential region of the firstrotating plate 121, may collide with a primary orsecondary collision surface 120a' or 120b' of each of thefirst wings 122, positioned opposite to the rotation direction of therotating plate 121. The first included angle θ1 may be an angle smaller than 100 degrees. - As shown in the examples of
FIGS. 3 to 5 , the V-shapedfirst wings 122 may be radially disposed on a circumferential side surface of the firstrotating plate 121 in thefirst fan member 120a. Sides of thefirst wings 122 may be connected to the firstrotating plate 122. The primary and secondary inlet winds A1 and A2 drawn into the interior of thefirst fan member 120a may collide with the primary orsecondary collision surface 120a' or 120b' of each of thefirst wings 122. - That is, the primary and secondary inlet winds A1 and A2 drawn into the first
rotating plate 121 may collide with the surfaces (the primary andsecondary collision surfaces 120a' and 120b' inFIG. 5 ) of each of thefirst wings 122, which face aninlet port 103a, due to the V shape of thefirst wings 122. However, the primary and secondary inlet winds A1 and A2 may avoid colliding with the rear surfaces (the opposite surface of the primary andsecondary collision surface 120a' or 120b' inFIG. 5 ) of each of thewings 122. - Due to the additional collision of the secondary inlet wind A2, 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 thefirst fan member 120 may be increased. Since the secondary inlet wind A2 may avoid colliding with the surface (the opposite surface of the primary orsecondary collision surface 120a' or 120b') of each of thewings 122 in the rotation direction D, the friction with the flow of air, caused by thefirst wings 122, may be minimized, and thus, the loss of pressure may be reduced. - In
FIGS. 3 to 5 , thefirst 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 firstrotating plate 121. However, this example is non-limiting, and it is unnecessary that the center line is parallel with the tangent line. As such, other suitable configurations may be employed. - For vacuum cleaners with output powers of 1200W and 2000W, the revolution per minute (RPM) of the
first fan member 120a having the V-shapedfirst wings 122 ofFIGS. 3 to 5 was compared with the RPM of thefan member 110a having thewings 112 of the related art. - In the vacuum cleaner with the output power of 1200W, the RPM of the
fan member 110a having thewings 112 of the related art showed 3800 RPM in load and 5200 RPM in unload. However, the RPM of thefirst fan member 120a having the V-shapedfirst wings 122 arranged similar to the examples shown inFIGS. 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. - In the vacuum cleaner with the output power of 2000W, the RPM of the
fan member 110a having thewings 112 of the related art showed 3900 RPM in load and 5200 RPM in unload. However, the RPM of thefirst fan member 120a having the V-shapedfirst wings 122 arranged similar to the examples shown inFIGS. 3 to 5 showed 4300 RPM in load and 5700 RPM in unload. Thus, it can be seen that the rotation speed may be increased. -
FIG. 6 illustrates a perspective view of an example of asecond fan member 130a.FIG. 7 illustrates a view showing an example of the structure of asecond wing 132.FIG. 8 illustrates a sectional view of an example of aturbine brush unit 100b illustrating the operational state of a secondturbine fan unit 130 having thesecond fan member 130a. - As shown in
FIGS. 6 to 8 , for example, thesecond fan member 130a has U-shapedsecond wings 132. The second included angle θ2 of each of thesecond wings 132 is an angle made by two lines that pass between a second curvature point C2 and ends of primary andsecond operating portions FIG. 7 ). The second included angle θ2 may be an angle smaller than about 100 degrees. Similar to the examples ofFIGS. 3 to 5 , sides of thesecond wings 132 may be fixed to a secondrotating plate 131. - A primary inlet wind A1 drawn into the interior of the
second fan member 130a may collide with aprimary collision surface 130a' of each of thesecond wings 132, and a secondary inlet wind A2 may then collide with asecondary collision surface 130b' of each of thesecond wings 132. - The primary inlet wind A1 drawn from an
inlet port 103a may collide with theprimary collision surface 130a' of theprimary operating portion 132a, thereby rotating thesecond fan member 130a. The secondary inlet wind A2 drawn into a fan member mounting portion P along the circumference of thesecond fan member 130a may collide with thesecondary collision surface 130b' of thesecondary operating portion 132b, thereby generating a secondary operating force B. - For a vacuum cleaner with an output power of 2000W, the RPM of the
second fan member 130a having the U-shapedsecond wings 132 ofFIGS. 6 to 8 was compared with the RPM of thefan member 110a having thewings 112 of the related art. - In the vacuum cleaner with the output power of 2000W, the RPM of the
fan member 110a having thewings 112 of the related art showed 3700 RPM in load and 5000 RPM in unload. - However, the RPM of the
second fan member 130a having the U-shapedsecond wings 132 arranged as shown in the examples ofFIGS. 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. As described above, 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. - Further, air that collides with the fan member collides with the wings so that the generation of a frictional force with respect to the rotation direction of the fan member may be avoided. Accordingly, the interruption of the flow of air may be decreased, and thus, the loss of pressure may be reduced.
- Furthermore, the rotation force of the fan member may be increased, and thus, the rotation force of a brush member may be increased. In this case, cleaning efficiency is enhanced.
- A number of examples have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
