Description

Embodiments of the present invention relate to a vacuum cleaner brush having a plurality of bristles arranged in a predetermined direction, a rotating cleaning body including the same, a cleaning unit including the same, and a vacuum cleaner including the same.

BACKGROUND ART Conventionally, in a rotary cleaning body used for a suction port of a vacuum cleaner, bristle material is arranged around the outer periphery of a rotatably supported brush stand. Then, the bristles are brought into sliding contact with the part to be cleaned to entangle the dust, and the entangled dust is conveyed to the suction port and sucked up, thereby removing the dust from the part to be cleaned.

If the dust contains thread-like dirt, and if the thread-like dirt is entangled with the hair material and cannot be sucked up from the suction port, the thread-like dirt may become entangled with the rotating cleaning member in a complicated manner as the rotating cleaning element rotates. . If the hair material entangled with filamentous debris is knocked over by the filamentous debris, the ability to remove dust from the area to be cleaned will be reduced, so it is preferable to remove the entangled filamentous debris, as this will increase the user's maintenance efforts. Become. In addition, it is necessary to remove the intricately entangled filamentous debris by cutting it with scissors or the like, and there is a risk of accidentally cutting the hair material at that time.

(First embodiment)
The first embodiment will be described below with reference to the drawings.

In FIGS. 1 to 4, 1 indicates a vacuum cleaner brush. The vacuum cleaner brush 1 has a plurality of bristles 10 connected by a connecting part 11 and gathered together by a base part 12, and formed into a wall shape or a band shape extending longitudinally in a predetermined direction shown by an arrow X in the figure. ing.

In this embodiment, the bristle section 10 is a bundle in which a plurality of bristle materials 100 whose base end portions are held on a base section 12 are brought together by a connecting section 11 . That is, the bristle section 10 is configured by combining a plurality of bristle materials 100 arranged in line along the base section 12 using the connecting section 11. The bristles 100 are grouped together so that the bristles 10 have a circular or elliptical shape when viewed from the length direction of the bristles 100. In the illustrated example, the bristles 10 are arranged in an elliptical shape in which the bristles 100 have their long axes in a predetermined direction. The bristles 10 are arranged sequentially in a predetermined direction. In the illustrated example, the adjacent bristles 10, 10 are arranged in succession in a predetermined direction at least at the root portions protruding from the base portion 12. Preferably, the tips of the adjacent bristles 10, 10 are close to or in contact with each other in a predetermined direction, so that the bristles 10, 10 are continuous in a predetermined direction.

As the hair material 100, natural yarn such as cotton yarn or synthetic resin fiber yarn is used. Each hair material 100 is formed into a thin elastic fiber shape. In this embodiment, each hair material 100 has a constant or substantially constant length. The hair material 100 may be configured by twisting a plurality of materials. Note that a large number of bristles 100 are densely arranged in the bristles 10 to form a wall that is substantially impermeable to dust, but they are thinned out in the figure for clarity of explanation. There is.

The base end portions of the plurality of bristles 10 are integrally held by the base portion 12. In this embodiment, the base end portions of all the bristles 10 are held by one base portion 12. The base portion 12 is formed longitudinally in a predetermined direction. The base portion 12 is integrally molded with the base end portions of the plurality of bristles 10, for example, by insert molding or double molding. The base portion 12 is made of, for example, a flexible synthetic resin such as elastomer.

The connecting portion 11 is a loosening suppressing portion that suppresses the degree of loosening of the hair material 100 in the bristles 10, and also serves as a prevention portion that prevents filamentous debris such as hair from entering the proximal end side of the bristles 10 or from getting entangled. Department. In this embodiment, the connecting portion 11 is a restraining portion or a defining portion that restricts the outside of the bristles 10 to define the range of the bristles 10 . The connecting portion 11 is formed by connecting the bristles 10 in a predetermined direction closer to the distal end in the length direction of the bristles 10 than the base portion 12, that is, on the upper side in FIG. 1, and extends in a predetermined direction. The connecting portion 11 connects a portion of the hair portion 10 in the length direction. That is, the connecting portion 11 connects the bristles 10 at a position between both ends of the portion of the bristles 10 that protrudes from the base portion 12 in the length direction.

In the illustrated example, the connecting part 11 is arranged at a position away from the base part 12 toward the tip end in the length direction of the bristles 10. Preferably, the connecting portion 11 connects the bristles 10 at a position between both ends of the portion of the bristles 10 that protrudes from the base portion 12 . That is, the bristles 10 have non-connected portions that are not connected to the connecting portion 11 on the distal end side and the proximal end side, respectively, in the portions that protrude from the base portion 12 . In the illustrated example, in the bristles 10, a first portion 101, which is a distal unconnected portion, is located closer to the distal end than the connecting portion 11, and a first portion 101, which is a distal unconnected portion, is located closer to the proximal end than the connecting portion 11, that is, the connecting portion 11 and the base. A second portion 102, which is a proximal non-connection portion, is located between the base portion 12 and the base portion 12.

The first part 101 is a dust removal part that scrapes off dust from the part to be cleaned. In the first part 101, the bristles 10 are restrained in the connecting part 11 on the base end side, and the bristles 100 are free ends on the distal end side and can be freely separated.

The second portion 102 is a bending portion that allows the bristles 10 to bend relative to the base portion 12. In the second portion 102, although the bristles 10 are restrained on the base end side and the distal end side, the bristles 100 do not come apart in the connecting portion 11 between the base end and the distal end. It is possible.

The lengths of the first portion 101 and the second portion 102 are set according to the position and range of the connecting portion 11 in the length direction of the bristles 10. There is a so-called trade-off relationship between the removal of dust by the vacuum cleaner brush 1 and the difficulty of getting entangled with filamentous dust, in which one comes at the expense of the other. The closer the connecting portion 11 is located to the tip of the bristle portion 10, and the narrower the range of the connecting portion 11, the longer the first portion 101 becomes, improving dust removal. The wider the range of the connecting portion 11 is, the shorter the first portion 101 is, and the more difficult it is for filamentous debris to become entangled with the bristles 10. Therefore, in the connecting part 11 of this embodiment, the position and range in the length direction of the bristles 10 are set so that these can be achieved in a desired balance. For example, the upper end portion of the connecting portion 11 is located at the center in the length direction of the bristles 10 that protrude from the base portion 12.

The connecting portion 11 may have any form as long as it can connect the bristles 10, 10 adjacent to each other in a predetermined direction. This is a sewn portion consisting of a linear body 111. In the illustrated example, the bristles 10, 10 adjacent in a predetermined direction are sewn together and connected by the connecting portion 11. Further, for example, the connecting portions 11 are set at a plurality of locations in the length direction of the hair portion 10. In this embodiment, the connecting portions 11 are set at two locations in the length direction of the bristles 10. These connecting parts 11 are located close to each other in the length direction of the hair part 10. In other words, the number of connections 11 in the length direction of the bristles 10 depends on the thickness of one linear body 110 or the other linear body 111 and the number of connections 11 in the length direction of the bristles 10. The range is set.

As the one linear body 110 and the other linear body 111, natural yarn or synthetic resin fiber yarn is used, respectively. The one linear body 110 and the other linear body 111 are made of a material that is thicker and stronger than the hair material 100. The one linear body 110 and the other linear body 111 may each be configured by twisting a plurality of materials. The one linear body 110 and the other linear body 111 may be made of the same material, have the same thickness, or may be different. One linear body 110 is located on one side of the bristle part 10, and the other linear body 111 is located on the other side of the bristle part 10. One side and the other side of the bristles 10 refer to one side and the other side in a direction intersecting or perpendicular to a predetermined direction and the height direction of the bristles 10. The upper side in FIG. 2 is one side of the bristles 10, and the lower side is the other side of the bristles 10. One linear body 110 and the other linear body 111 are located on opposite sides of the bristles 10 in a direction intersecting or orthogonal to the length direction thereof. The one linear body 110 and the other linear body 111 are entwined with each other between the bristles 10 and 10, tied at their ends, and arranged to surround the side of the bristled part 10.

Preferably, one linear body 110 is arranged in a meandering manner on one side of the hair portion 10. One linear body 110 is arranged in a curved manner along one side of the bristles 10, and is formed in a loop shape at a position on the other side of the bristles 10 between the bristles 10, 10. It is entangled with the linear body 111. Preferably, at least one linear body 110 is made of a material of a different color from the bristles 10. Therefore, one linear body 110 exhibits a continuous or discontinuous stitch-like design extending in a predetermined direction in a part of the length direction of the bristles 10. In this case, preferably, the other linear body 111 has greater strength than the one linear body 110.

At the position of the connecting portion 11 shown in FIGS. 1 to 3, the bristles 10 are harder than the first portion 101 and the second portion 102. The hardness of the connecting portion 11 is set depending on the required degree of disintegration of the bristle material 100 within the bristle portion 10. In this embodiment, the hardness of the connecting portion 11 is set according to the squeezing or tightening of the bristles 10 by one linear body 110 and the other linear body 111. The greater the constriction or tightening of the bristles 10 by one linear body 110 and the other linear body 111, the harder the connecting portion 11 is formed. The harder the connecting portion 11 is, the less the bristles 10 and the bristles 100 of the second portion 102 come loose within the connecting portion 11, and the stronger the contact of the bristles 10 with the part to be cleaned becomes.

As shown in FIG. 5, the vacuum cleaner brush 1 is used in a rotating cleaning body 2. The rotating cleaning body 2 is also called a rotating brush, and is rotated to scrape off dust from the area to be cleaned using the vacuum cleaner brush 1.

The rotary cleaning body 2 has a shaft-shaped base portion 20 . The base portion 20 constitutes a rotating shaft portion of the rotary cleaning body 2.

A vacuum cleaner brush 1 is attached to the stand 20. In this embodiment, a vacuum cleaner brush 1, which is a first vacuum cleaner brush, and a vacuum cleaner brush 21, which is a second vacuum cleaner brush, are attached to the stand 20. The vacuum cleaner brush 21 is formed into a wall shape or a band shape extending in a predetermined direction, with the base end side of a plurality of bristles 211 being held on a base part 210. The vacuum cleaner brush 21 does not have a structure corresponding to the connection part 11 of the vacuum cleaner brush 1, that is, the bristles 211 are of a non-connected type. The base portion 210 and the bristles 211 of the vacuum cleaner brush 21 are configured in the same manner as the base portion 12 and the bristles 10 of the vacuum cleaner brush 1, so a detailed explanation will be omitted. The material of the bristle material 2110 of the base part 210 and the bristle part 211 of the vacuum cleaner brush 21, the shape such as length and thickness, the arrangement density of the bristle material 2110, that is, the number of bristle material 2110 per unit area, and the color etc. may be the same or substantially the same as the base portion 12 and the bristle material 100 of the bristle portion 10 of the vacuum cleaner brush 1, or may be different.

In this embodiment, the vacuum cleaner brush 21 and the vacuum cleaner brush 1 differ in the amount of dust that is to be removed from the area to be cleaned. The purpose of the bristles 211 of the vacuum cleaner brush 21 is to scrape off, for example, cotton waste, thread-like waste, etc., and the bristle part 10 of the vacuum cleaner brush 1 is intended to scrape off, for example, solid waste such as sand and powder. Its purpose is to scrape up trash. For example, the vacuum cleaner brush 1 can be suitably used for cleaning hard planar areas to be cleaned such as wooden floors, but is especially suitable for cleaning thick or deep areas such as carpets.

Inhale with air.

Further, in the cleaning section 3, the rotary cleaning body 2 rotates to scrape up dust from the section to be cleaned. At this time, the bristle materials 100 and 2110 are separated from the connecting part 11 of the bristle part 10 of the vacuum cleaner brush 1, that is, the first part 101, and the bristle part 211 of the vacuum cleaner brush 21, and the carpet is The dust that has entered the part to be cleaned is effectively scraped up and carried to the suction port 3010.

The dust sucked in from the suction port 3010 is separated from the air in the dust collecting section 41 and accumulated in the dust collecting section 41 .

As described above, in the present embodiment, the vacuum cleaner brush 1 has a plurality of bristles 10 whose base end portions are held by the base portion 12 and which are lined up in a predetermined direction. Since the bristles 10 are connected by the connecting portion 11 on the tip side, the range in which the bristles 100 of the bristles 10 come apart is limited to a narrow range on the tip side than the connecting portion 11, which is the first portion 101 in this embodiment, Dust on the part to be cleaned, including filamentous dirt such as hair, is removed by attaching it to the bristles 100 and lifting it, rather than entangling it with the bristles 100 of the bristles 10. Therefore, the chance that filamentous waste gets entangled with the hair material 100 is greatly reduced. Therefore, it is difficult for filamentous debris to enter the base of the bristles 100 of the bristles 10, and it is difficult for filamentous debris to become entangled. With regular vacuum cleaner brushes, the bristles come loose to the base near the base, so entangled thread-like debris gets deep into the bristles' roots, and once tangled, it is difficult to remove. In the vacuum cleaner brush 1 of this embodiment, since the bristles 10 have the connecting portion 11, even if filamentous dirt gets in, it will remain in a shallow range up to the connecting portion 11, that is, within the first portion 101, so it can be easily removed. The user can untie it with his/her fingers or the like, which greatly reduces the hassle of maintenance. Further, since the bristles 10 do not remain in a collapsed state due to entanglement with filamentous dirt, the ability to scrape up dust from the area to be cleaned, that is, the ability to remove dust, does not deteriorate.

In this respect, since the vacuum cleaner brush 21 does not have the connecting part 11 like the vacuum cleaner brush 1, filamentous dirt can easily get into the base of the bristles 211 compared to the vacuum cleaner brush 1. . However, in the rotary cleaning body 2, the vacuum cleaner brush 1 and the vacuum cleaner brush 21 are arranged alternately in the circumferential direction, so if one end of the filamentous waste S is Even if the filamentous dirt S reaches the root of the bristles 211 of the brush 21 in the vicinity of the base 210, the other end of the filamentous dirt S is moved to the vacuum cleaner brush 1 side adjacent to the vacuum cleaner brush 21 by the rotation of the rotary cleaning body 2. When extended, the bristles 10 of the vacuum cleaner brush 1 do not reach the root portion near the base portion 12. Therefore, the filamentous dirt S is suspended from the base part 20 between the vacuum cleaner brushes 21 and 1 in a state where it is stretched between the bristles 211 of the vacuum cleaner brush 21 and the bristles 10 of the vacuum cleaner brush 1. Therefore, the filamentous waste S can be easily loosened by inserting a cutting means such as scissors into the floating part and cutting the filamentous waste S.

By bundling a plurality of bristles 100 to form a plurality of bristles 10 and connecting these bristles 10 by connecting parts 11, the plural bristles 10 are connected to each other by connecting parts 11, thereby preventing entanglement of filamentous waste. While suppressing this, the bristle material 100 is spread out within the connecting portion 11, and the ability to scrape up dust from the portion to be cleaned can be maintained.

By arranging the connecting portion 11 between the lengthwise ends of the bristles 10 protruding from the base portion 12, the bristles are formed between the proximal end of the connecting portion 11 and the base portion 12. Since a second portion 102 is formed in which the bristles 100 of the portion 10 are separated within the connecting portion 11, the bristles 10 become soft and pliable in this second portion 102, and the strength of contact with the portion to be cleaned is reduced. Ru. The stronger the contact of the bristles 10 with the part to be cleaned, the greater the load for rotating the rotary cleaning body 2 and the larger the current consumption value of the drive unit 31. By doing so, it is possible to suppress an increase in the current consumption value of the drive unit 31, which is correlated with the strength of contact of the bristles 10 with the part to be cleaned, and also to prevent the first portion 101 from coming apart on the tip side of the bristles 10. Dust can be effectively scraped up.

The connecting portion 11 includes one linear body 110 located on one side of the bristles 10 and another linear body 111 located on the other side of the bristles 10 and entwined with the one linear body 110. By configuring the sewing portion as a sewing portion, the connecting portion 11 can be easily and stably formed using a manufacturing device such as a sewing machine, for example.

Furthermore, since it is possible to make one linear body 110 and another linear body 111 separate members, materials and thicknesses suitable for one linear body 110 and other linear body 111 can be selected. It becomes possible to select the size as appropriate.

By positioning one linear body 110 of the connecting part 11 in a meandering manner on one side of the hair part 10, the connection can be made according to the meandering condition of the one linear body 110, that is, the pitch of the meandering, the width in a predetermined direction, etc. The hardness of squeezing or tightening the bristles 10 by the portion 11 can be adjusted. The looser the squeezing or tightening of the bristles 10 by the connecting part 11, the more easily the bristles 100 of the bristles 10 come apart within the connecting part 11, and the more the bristles 10 are separated between the connecting part 11 and the base part 12. The second portion 102 can be soft and pliable, and the strength of contact of the bristles 10 against the area to be cleaned is reduced. Therefore, the strength of contact of the bristles 10 against the part to be cleaned can be adjusted depending on the hardness of squeezing or tightening of the bristles 10 by the connecting part 11. The current consumption value of the correlated drive unit 31 can be adjusted.

By making the color of the first linear body 110 of the connecting portion 11 different from the color of the bristles 10, it is possible to make the first linear body 110 stand out from the bristles 10. A stitch-like design can be created in the bristles 10 by the meandering of the bristles 110, and the design can be improved.

The base end side of the bristles 10 of the vacuum cleaner brush 1, in this embodiment the base part 12, is held in the recess 200 extending in the axial direction on the outer surface of the shaft-shaped base part 20, and the rotary cleaning body 2 is By doing so, it is possible to provide a rotary cleaning body 2 in which filamentous dirt is less likely to get entangled with the bristles 10 of the vacuum cleaner brush 1.

Since at least a part of the connecting part 11 of the vacuum cleaner brush 1 is located outside the edge of the recess 200 of the base part 20, the bristles 10 that come into contact with the part to be cleaned due to the rotation of the rotary cleaning body 2 are The portion protruding from the base portion 12 becomes more flexible. Therefore, the tip of the bristles 10 of the vacuum cleaner brush 1 can be brought into elastic contact with the part to be cleaned, making it possible to efficiently scrape up dust from the part to be cleaned. and the part to be cleaned becomes less likely to be damaged.

In this embodiment, since the connecting part 11 of the vacuum cleaner brush 1 is located away from the edge of the recess 200 of the base part 20 on the outside, there is a gap between the connecting part 11 of the bristle part 10 and the base part 12. Since the second portion 102 of the bristles 10 is exposed to the outside of the outer surface of the base portion 20, the bristles 10 that come into contact with the area to be cleaned due to the rotation of the rotary cleaning body 2 are made more flexible by the second portion 102. I can do it.

By equipping the cleaning section 3 with the above-mentioned rotary cleaning body 2, it is possible to provide the cleaning section 3 that is easy to maintain and has an excellent ability to scrape up dust from the section to be cleaned.

By using the cleaning unit 3 described above in the vacuum cleaner 4, it is possible to provide the vacuum cleaner 4 with excellent maintainability and high cleaning performance.
