Definitions

  • the present invention relates to a vacuum cleaner. More particularly, the present invention relates to a brush assembly for a vacuum cleaner.
  • a vacuum cleaner includes a brush assembly, an extension pipe, a handle, a suction hose, and a cleaner body.
  • the brush assembly has a suction port facing a cleaning surface and sucking dust, or dirt, and the like (hereinafter referred to collectively as contaminants) with air.
  • the extension pipe is in fluid communication with the brush assembly to guide the sucked contaminants and air.
  • the suction hose guides the air with contaminants moving through the extension pipe to the cleaner body.
  • the cleaner body has a vacuum generator for generating suction force.
  • a motor of the vacuum generator disposed in the cleaner body generates suction force. Contaminants on the cleaning surface are sucked with air through the suction port formed in the brush assembly by the suction force. Contaminants and air sucked through the suction port are moved to the cleaner body through the extension pipe and the suction hose. Contaminants that enter the cleaner body are separated from air and then collected in a dust collector. Therefore, air and contaminants pass through the brush assembly, the extension pipe, the suction hose, and the cleaner body.
  • a user grasps the handle to push or pull the brush assembly.
  • the suction port of the brush assembly approaches the cleaning surface as a result of the applied force while the suction force applies negative pressure to the suction port.
  • the user should push the handle forward with a fairly strong force for the brush assembly to move forward.
  • the suction port of the brush assembly receives the applied force in a direction that causes separation from the cleaning surface so that the applied force cancels out the suction force. Consequently, high negative pressure is not applied to the suction port of the brush assembly.
  • the user can pull the handle backward with a weak force for the brush assembly to move backward.
  • handling force force that the user should apply to the handle
  • a handling force required to push the brush assembly forward is greater than a handling force required to pull the brush assembly backward. Therefore, it is inconvenient for the user to push the brush assembly forward.
  • cleaning a soft surface such as a carpet it is hard to push the brush assembly forward because the cleaning surface sticks to the brush assembly.
  • An aspect of the present invention is to provide a brush assembly for a vacuum cleaner and a vacuum cleaner employing the same that requires weaker force than the conventional art to push the brush assembly forward.
  • a first non-limiting aspect of the invention provides a brush assembly for a vacuum cleaner comprising, which includes: a brush body having a suction pathway in fluid communication with a cleaner body of the vacuum cleaner; a brush having a suction port in fluid communication with the suction pathway of the brush body, the brush being disposed to rotate at the brush body; and a sealing part configured to seal between the suction pathway and the suction port for the brush to rotate with respect to the brush body, the sealing part forming a gap for outside air to enter the suction pathway of the brush body through as the brush rotates with respect to the brush body.
  • a second non-limiting aspect of the invention provides vacuum cleaner that includes: a cleaner body configured to generate suction force; an extension pipe assembly in fluid communication with the cleaner body, the extension pipe assembly forming a passage for contaminants; and a brush assembly in fluid communication with the extension pipe assembly, the brush assembly being configured to draw in the contaminants, wherein the brush assembly includes, a brush body having a suction pathway in fluid communication with the extension pipe assembly, a brush having a suction port in fluid communication with the suction pathway of the brush body, the brush being disposed to rotate at the brush body, and a sealing part configured to enable outside air to enter the suction pathway of the brush body as the brush assembly moves in a first direction, and configured to prevent outside air from entering the suction pathway of the brush body as the brush assembly moves in a second direction.

  • a brush assembly 1 for a vacuum cleaner may include a brush body 10, a brush 20, and a sealing part 30.
  • the brush body 10 may include a suction pathway 11 in fluid communication with a cleaner body 110 (see Fig. 10).
  • the suction pathway 11 may form a passage through which the sucked air and contaminants move and may be disposed inside the brush body 10.
  • An end of an extension pipe 121 in fluid communication with the suction pathway 11 may be connected with a side of the brush body 10.
  • the brush 20 may be disposed at the other end of the suction pathway 11 to rotate with respect to the brush body 10 within a predetermined angle range.
  • a pair of wheels 5 may be disposed at both sides of the brush body 10 for the brush body 10 to move on the cleaning surface.
  • the brush 20 sucks contaminants from the cleaning surface, and may include a suction port 21 in fluid communication with the suction pathway 11 of the brush body 10.
  • the brush may be disposed at the brush body 10 to rotate.
  • the brush 20 may be disposed to rotate with respect to the brush body 10 within a predetermined angle range via a pivot point, e.g., a hinge, 40 disposed at a side of an upper portion of the suction port 21. It may be preferable that the brush 20 can rotate with respect to the brush body 10 by approximately 15-20 degrees.
  • a cover 29 may be disposed on the brush 20 to improve the appearance.
  • the sealing part 30 may be configured to seal between the suction pathway 11 and the suction port 21 so that air and contaminants sucked into the suction port 21 can move to the suction pathway 11 as the brush 20 rotates with respect to the brush body 10.
  • the sealing part 30 may form a gap G (see Fig. 5), through which outside air may directly enter the suction pathway 11 of the brush body 10 as the brush 20 rotates over a predetermined angle with respect to the brush body 10.
  • the sealing part 30 may include an upper sealing 31 formed at the suction pathway 11, and an under sealing 32 extending upward from a top end of the suction port 30 and configured to slide on the upper sealing 31.
  • the upper and under sealing 31 and 32 may each be formed in a substantially rectangular pipe shape.
  • a front wall 33 of the under sealing 32 may be lower than both sidewalls 34, 35 thereof.
  • the front wall 33 among four walls 33, 34, 35, 36 of the under sealing 32 may be farthest away from a rotation center C on which the brush 20 rotates with respect to the brush body 10 (namely, the hinge 40).
  • the under sealing 32 may be bent based on the hinge 40 so that the under sealing 32 can slide smoothly inside the upper sealing 31 as the brush 20 rotates with respect to the brush body 10.
  • a gap G through which outside air enters is formed between a top end 33a of the front wall 33 of the under sealing 32 and a bottom end 31a of the upper sealing 31, as shown in Fig. 5.
  • the top end 33a of the front wall 33 of the under sealing 32 and the bottom end 31a of the upper sealing 31 may form gap G through which outside air enters.
  • the gap G has a maximum size.
  • the gap G formed by the sealing part 30 may have a maximum size.
  • Another gap forming method may be to form at least one outside air hole 39 so that outside air may enter through on the front wall 33' of the under sealing 32 as shown in Fig. 6. As the brush 20 rotates with respect to the brush body 10, the bottom end 31a of the upper sealing 31 may open or close the at least one outside air hole 39.
  • the vacuum cleaner is being used to clean a surface that is soft, such as a soft carpet.
  • the handle 123 see Fig. 10
  • the extension pipe assembly 120 see Fig. 10
  • the brush assembly 1 is enabled to move on the carpet in a direction of arrow A of Fig. 7 by the pair of wheels 5.
  • the brush assembly 1 may receive approximately simultaneously both a first down force applied when the user pushes the handle 123 forward, and the second down force applied by the suction force operating in the suction port 21 of the brush 20. Therefore, as the user pushes the handle 123 forward, the brush 20 of the brush assembly 1 may rotate downward with respect to the brush body 10 based on the hinge 40 so that the gap G through which outside air D enters the suction pathway 11 of the brush body 10 is formed on the sealing part 30.
  • the under sealing 32 of the brush 20 may separate from the upper sealing 31 of the brush body 10 so that gap G may be formed between the top end 33a of the front wall 33 of the under sealing 32 and the bottom end 31a of the upper sealing 31 as shown in Figs. 7 and 8.
  • Outside air D may then directly enter the suction pathway 11 through the gap G between the under sealing 32 and the upper sealing 31, so that negative pressure applied to the suction port 21 decreases.
  • a magnitude of the force required for the user to push the brush assembly 1 is decreased as compared with the conventional vacuum cleaner. Consequently, it is easier to clean soft cleaning surface such as a carpet.
  • the brush assembly 1 may be caused to move on the carpet in a direction of arrow B of Fig. 3 by a pair of wheels 5. At this time, the brush assembly 1 receives both an upward force caused when the user pulls the handle 123 backwards, and downward force caused by the suction force operating in the suction port 21 of the brush 20. Then when the user pulls the brush assembly 1, the upward force and the downward force applied to the brush assembly 1 cancel each other so that magnitude of force required to pull the brush assembly 1 is smaller than the force required to push it Therefore, when pulling the brush assembly 1, the brush 20 does not rotate with respect to the brush body 10 and may remain parallel with the cleaning surface as shown in Fig. 3.
  • the under sealing 32 of the sealing part 30 may be positioned on the upper sealing 31 (as shown in Fig. 9) so that outside air cannot directly enter the suction pathway 11 of the brush body 10 through the sealing part 30. As a result, the user may not have to apply much force to pull the brush assembly 1.
  • the vacuum cleaner 100 may include a cleaner body 110, an extension pipe assembly 120, and a brush assembly 1.
  • the cleaner body 110 generates suction force to suck in contaminants.
  • the cleaner body 110 may include a vacuum generator (not shown) for generating suction force.
  • the cleaner body 110 may include a dust collector (not shown) that separates and collects contaminants from air sucked via the brush assembly 1 and the extension pipe assembly 120.
  • the extension pipe assembly 120 may enable the cleaner body 110 to be in fluid communication with the brush assembly 1.
  • the extension pipe assembly 120 may include an extension pipe 121, a handle 123, and a suction hose 122.
  • the extension pipe 121 may be configured to guide the sucked contaminants and may be in fluid communication with the brush assembly 1.
  • the handle 123 may be grasped by the user to push or pull the brush assembly 1 when in use.
  • the suction hose 122 may guide air containing contaminants guided through the extension pipe 121 to the cleaner body 110.
  • the brush assembly 1 may be in fluid communication with the extension pipe 121 of the extension pipe assembly 120 and may suck contaminants from the cleaning surface.
  • the brush assembly 1 may include a brush body 10, a brush 20, and a sealing part 30.
  • the brush body 10 may have a suction pathway 11 in fluid communication with the extension pipe 121.
  • the brush 20 may have a suction port 21 in fluid communication with the suction pathway 11 of the brush body 10, and may be disposed to rotate with respect to an end of the brush body 10 by a predetermined angle. As the brush assembly 1 moves in a direction, the brush 20 may rotate with respect to the brush body 10 so that the sealing part 30 may form a gap G for outside air to directly enter the suction pathway 11 of the brush body 10 through.
  • the sealing part 30 may close the gap G
  • the sealing part 30 may include an upper sealing 31 formed at a bottom end of the suction pathway 11, and an under sealing 32 extending from the top end of the suction port 21 of the brush 20 and sliding on the upper sealing 31.
  • the brush 20 may rotate with respect to the brush body 10 so that a gap G through which air may enter the suction pathway 11 of the brush body 10 may be formed between a bottom end 31a of the upper sealing 31 and a top end 33a of the under sealing 32.
  • the brush assembly 1 when the handle 123 is pushed, the brush assembly 1 may move forward to allow the gap G of the sealing part 30 to open.
  • the brush assembly 1 may move backward to allow the gap G of the sealing part 30 to close.
  • the brush body 10, the brush 20, and the sealing part 30 included as part of the brush assembly 1 may be the same as the above description.
  • a user When cleaning a carpet, a user powers on the vacuum cleaner 100, grasps the handle 123 of the extension pipe assembly 120, and then pushes or pulls the brush assembly 1 so as to clean the carpet. As the user grasps and pushes the handle 123, the brush assembly 1 is moved forward. Then, the brush 20 may rotate with respect to the brush body 10, thereby inclining downwardly with respect to the brush body 10. As a result, a gap G may be formed between the under sealing 32 of the brush 20 and the upper sealing 31 of the brush body 10. As the gap G is formed between the under sealing 32 and the upper sealing 31, outside air D may directly enter the suction pathway 11 through the gap G as shown in Fig. 8.
  • the negative pressure applied to the suction port 21 may decrease, so that magnitude of force required for the user to push the brush assembly 1 is decreased.
  • it is more convenient for the user to clean the carpet as compared with the conventional vacuum cleaner.
  • the brush assembly 1 when the user pulls the handle 123, the brush assembly 1 is moved backward. At this time, the brush 20 may remain parallel with the brush body 10 as shown in Fig. 3. As the brush assembly 1 moves backward, magnitude of the negative pressure applied to the suction port 21 is small (as described above), so that a magnitude of the force required for the user to pull the brush assembly 1 is not great.
  • the user when cleaning carpet using the vacuum cleaner 100 according to an embodiment of the present invention, the user is required to apply less force as compared with the conventional vacuum cleaner.
  • the user can clean by applying a force of substantially equal magnitude to the force required for the conventional vacuum cleaner. Therefore, with the present invention, it is more convenient for the user to clean the carpet as compared with the conventional vacuum cleaner.
