Description

[Technical Field]

[0001] The present invention relates to a rotary cleaning body used in an electric vacuum cleaner and a suction tool of the electric vacuum cleaner equipped with the rotary cleaning body. [Background technology]

[0002] BACKGROUND ART Conventionally, a rotary cleaning body provided with a fiber waste collection section capable of collecting hair, thread-like fibers, and the like is known (Patent Document 1).

[0003] The rotary cleaning body described in Patent Document 1 comprises a rotary cleaning member that is driven to rotate, a bearing that supports the rotary cleaning member by a connecting shaft, an end cap provided at the end of the rotary cleaning member, a disk body that is provided between the end cap and the bearing and is separable from the end cap, and a separable bristle reservoir that is fitted onto the connecting shaft and is provided between the disk body and the end cap, and has an outer diameter smaller than the diameters of the disk body and the end cap; and when the disk body and the end cap are separated, at least one end of the bristle reservoir is open. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5366719 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the rotary cleaning body described in Patent Document 1, the rotary cleaning member is journaled from its end by a connecting shaft, and the hair reservoir is fitted onto the connecting shaft, so when disposing of hair or thread-like fibers accumulated in the hair reservoir, the connecting shaft must be removed from the rotary cleaning member, and as this is removed more frequently, the rotary cleaning body is prone to wobbling during rotation.Furthermore, because the hair reservoir is located between the end cap on the rotary cleaning member side and the disc on the connecting shaft side, when disposing of hair or thread-like fibers, the entire rotary cleaning body must be moved above a trash can or the like, which causes dust adhering to the rotary cleaning member to fall off during the movement, which is a problem.

[0006] The present invention solves the above-mentioned conventional problems, and aims to provide a rotating cleaning body that can prevent core wobble, easily collect hair, thread-like fibers, etc., and can be easily disposed of without soiling the surrounding area. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems of the conventional art, the invention of claim 1 provides a rotating cleaning body having a rotating rotor with a cleaning body and a rotor body to which the cleaning body is fixed, a bracket fixed to the end of the rotor body and having a rotating shaft that can be inserted into a bearing body installed in the suction tool of an electric vacuum cleaner, and a fiber waste container having an insertion hole into which the rotating shaft is inserted and fixed to the end of the rotor body, wherein the fiber waste container has a fiber waste container section that can store hair and thread-like fibers attached to the cleaning body, is detachable from the rotor body and the bracket, and the fiber waste container is disassembled.

[0008] In the invention of claim 1, the bracket is provided with a rotating shaft that can be inserted into the bearing body, the fiber waste container is detachable from the rotor body and the bracket, and the fiber waste container section is disassembled, so that the core of the rotating cleaning body can be prevented from wobbling, and hair, thread-like fibers, etc. can be easily collected and disposed of without soiling the surrounding area.

[0009] The invention of claim 2 is characterized in that, in the invention of claim 1, the fiber waste storage section of the fiber waste storage body is formed of a groove having an approximately concave axial cross section, and the bottom surface of the groove is formed as a conical inclined surface whose outer diameter increases toward the rotor body. This makes it easier to store fiber waste in the fiber waste storage section and prevents fiber waste that has once been stored from being discharged to the outside from the fiber waste storage section. Furthermore, because the fiber waste is concentrated in a position away from the rotor body within the fiber waste storage section due to vibration during rotation, it is possible to reduce the re-adhesion of fiber waste to the cleaning body.

[0010] The invention of claim 3 is characterized in that, in the invention of claim 1, the fiber waste storage compartment of the fiber waste storage body is formed of a groove having an approximately concave axial cross section, and the outer peripheral surface of the fiber waste storage body on the rotor body side and / or the outer peripheral surface on the opposite side from the rotor body, adjacent to the groove, is formed as a conical slope whose outer diameter decreases toward the groove. This makes it easier to store fiber waste in the fiber waste storage compartment and prevents fiber waste once stored therein from being discharged to the outside from the fiber waste storage compartment. Furthermore, since fiber waste is more easily transported into the fiber waste storage compartment due to vibration during rotation, it is possible to reduce the likelihood of fiber waste re-adhering to the cleaning body.

[0011] The invention of claim 4 is characterized in that, in the invention of claim 1 or 2, the fiber waste storage section of the fiber waste storage body is formed of a groove having an approximately concave cross section in the axial direction, and the inner surface of the groove is formed as an inclined surface that narrows toward the opening side of the groove. This makes it possible to suppress the spread of fiber waste and prevent fiber waste that has once been stored from being discharged to the outside from the fiber waste storage section.

[0012] The invention of claim 5 is characterized in that, in the invention of claim 1 or 2, the fiber waste storage section of the fiber waste storage body is formed of a groove having an approximately concave axial cross section, and the outer circumferential surface of the rotor body side adjacent to the groove of the fiber waste storage body is formed on approximately the same plane as the outer circumferential surface of the rotor body. This makes it easier for the cleaning body to fall toward the fiber waste storage section, and since there is no step between it and the fiber waste storage section, it is easier to store fiber waste in the fiber waste storage section.

[0013] The invention of claim 6 is characterized in that, in the invention of claim 1 or 2, one end of the cleaning body is fixed to the fiber waste container, and the cleaning body can be attached and detached from the rotor body together with the fiber waste container. This makes it possible to simultaneously dispose of the fiber waste contained in the fiber waste container and the fiber waste attached to the cleaning body, making it easy to maintain the rotating cleaning body.

[0014] The invention of claim 7 is characterized in that, in the invention of claim 1 or 2, the rotor body is formed with a plurality of brush bases on its outer circumferential surface from one end to the other in the longitudinal direction, with gaps formed between adjacent brush bases from one end to the other in the longitudinal direction, and a fiber waste discharge port consisting of a notch or hole formed at a predetermined location on the bracket continuous with the end of the gap. This allows fiber waste, dust, etc. that has accumulated in the gaps between the brush bases to be easily discharged to the outside through the fiber waste discharge port consisting of the notch or hole while flowing down the side of the brush base, making maintenance of the rotating cleaning body easy.

[0015] The invention of claim 8 is characterized in that, in the invention of claim 1 or 2, the cleaning element has a substantially plate-shaped base and a scraping part extending substantially perpendicularly from a side surface of the base, one longitudinal end of the cleaning element extends to the vicinity of the fiber waste storage compartment of the fiber waste storage compartment, and is arranged so that a part of the scraping part can swing to the fiber waste storage compartment when the rotating cleaning element rotates. This makes it easier to transfer fiber waste adhering to the scraping part of the cleaning element to the fiber waste storage compartment.

[0016] The invention of claim 9 is an invention of a suction tool for a vacuum cleaner, characterized by comprising a housing, a suction port formed in the housing, a bearing body installed near the suction port, and a rotary cleaning body connected to the bearing body as set forth in any one of claims 1 to 8. This makes it possible to prevent the rotary cleaning body from wobbling, and to provide a suction tool for a vacuum cleaner that can easily collect hair, thread-like fibers, etc. and dispose of them without soiling the surrounding area. [Effects of the Invention]

[0017] The invention of claim 1 of the rotating cleaning body can prevent the core of the rotating cleaning body from wobbling, and can easily collect hair and thread-like fibers, allowing them to be easily disposed of without soiling the surrounding area. Furthermore, the inventions of claims 2 and 3 can make it easier to store fiber waste in the fiber waste storage section, and can prevent fiber waste once stored from being discharged to the outside from the fiber waste storage section.

[0018] The invention of claim 4 can suppress the spread of fiber waste and prevent fiber waste that has been collected from being discharged to the outside from the fiber waste collection section. The invention of claim 5 can make it easier to collect fiber waste in the fiber waste collection section. The invention of claim 6 can simultaneously dispose of fiber waste collected in the fiber waste collection section and fiber waste attached to the cleaning body, making it easy to maintain the rotating cleaning body.

[0019] The invention of claim 7 allows fiber waste and dust accumulated in the gaps between the brush bases to be easily discharged to the outside through the fiber waste discharge port, making it easy to maintain the rotating cleaning body.

[Figure 7] FIG. 10 is a perspective view showing another embodiment of the rotary cleaning body according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to this embodiment. Fig. 1 is a perspective view showing a vacuum cleaner equipped with a suction tool of the present invention, and Fig. 2 is a bottom view of the same. The suction tool of the vacuum cleaner of the present invention will be described below with reference to these drawings.

[0022] Self-propelled vacuum cleaner 40 has a housing 41 constituting bottom surface 41a, a suction port 42 formed in housing 41, bearings 7a and 7b installed near suction port 42, and a vacuum cleaner suction tool 30 equipped with a rotary cleaning body 10 connected to bearings 7a and 7b. Rotary cleaning body 10 is rotatably mounted by a drive mechanism such as a motor housed in vacuum cleaner body 40a. Furthermore, a plurality of running wheels 43a, 43b, and 43c are rotatably mounted on bottom surface 41a, and two of the running wheels 43a and 43b are connected to a driving motor and function as drive wheels. Note that the vacuum cleaner suction tool according to the present invention is not limited to self-propelled vacuum cleaners, and the present invention encompasses any vacuum cleaner suction tool equipped with a housing, a suction port formed in the housing, bearings installed near the suction port, and a rotary cleaning body according to the present invention connected to the bearings.

[0023] Fig. 3(a) is a front view of a rotary cleaning body according to the present invention, and Fig. 3(b) is an exploded front view of the rotary cleaning body according to the present invention. Fig. 4(a) is a front view of a fiber waste container that constitutes the rotary cleaning body, and Fig. 4(b) is a cross-sectional view taken along line AA in Fig. 4(a). The rotary cleaning body according to the present invention will be described in detail below using these figures.

[0024] The rotating cleaning body 10 of the present invention comprises a rotating rotor 3 having a cleaning body 1 and a rotor body 2 to which the cleaning body 1 is fixed, a bracket 4 fixed to the end of the rotor body 2 and having a rotating shaft 4a that can be inserted into a bearing body 7a installed in the suction tool of an electric vacuum cleaner, and a fiber waste container 5 having an insertion hole 5c into which the rotating shaft 4a is inserted and fixed to the end of the rotor body 2.

[0025] The fiber waste container 5 is provided with a fiber waste container section 6 that can store hair, thread-like fibers, etc. that are attached to the cleaning body 1, and is detachable from the rotor body 2 and the bracket 4. The fiber waste container section 6 can be disassembled by separating the fiber waste container 5 into a flange body 5a and a fitting body 5b.

[0026] By configuring the rotary cleaning body 10 as described above, it is possible to prevent the core of the rotary cleaning body 10 from wobbling, and also to easily collect hair, thread-like fibers, etc., and dispose of them without soiling the surrounding area.

[0027] The fiber waste collection section 6 of the fiber waste container 5 comprises a groove 6 having an approximately concave cross section in the axial direction, and the bottom surface 6a of the groove 6 is formed as a conical slope whose outer diameter increases toward the rotor body 2. This makes it easier to collect fiber waste in the fiber waste collection section 6 and prevents fiber waste that has once been collected from being discharged to the outside from the fiber waste collection section 6. Furthermore, since the fiber waste is concentrated in a position away from the rotor body 2 within the fiber waste collection section 6 due to vibration during rotation, it is possible to reduce the likelihood of fiber waste re-adhering to the cleaning body 1. Furthermore, by forming the mating surface between the flange body 5a and the mating body 5b at the position of the bottom surface 6a where the outer diameter of the groove 6 where the fiber waste converges becomes smaller, tangled fiber waste can be more easily discharged.

[0028] The fiber waste storage section 6 of the fiber waste storage body 5 is formed of a groove 6 having a generally concave axial cross section, and the outer peripheral surface 5d on the rotor body 2 side and the outer peripheral surface 5e on the opposite side from the rotor body 2, which are adjacent to the groove 6 of the fiber waste storage body 5, are formed as conical slopes whose outer diameter decreases toward the groove 6. Note that the present invention also includes a case where either the outer peripheral surface 5d on the rotor body 2 side or the outer peripheral surface 5e on the opposite side from the rotor body 2 is formed as a conical slope whose outer diameter decreases toward the groove 6. This makes it easier to store fiber waste in the fiber waste storage section 6 and prevents fiber waste once stored therein from being discharged to the outside from the fiber waste storage section 6. Furthermore, since fiber waste is more easily transported into the fiber waste storage section 6 due to vibration during rotation, redeposition of fiber waste to the cleaning body 1 can be reduced.

[0029] The fiber waste storage section 6 of the fiber waste storage body 5 is made up of a groove 6 having an approximately concave cross section in the axial direction, and the inner surface 6b of the groove 6 is formed as an inclined surface that narrows toward the opening 6c of the groove 6. This prevents the fiber waste from spreading and also prevents fiber waste that has been stored therein from being discharged from the fiber waste storage section 6 to the outside.

[0030] 5(a) to 5(c) are front views showing the procedure for removing fibrous waste. The procedure for removing fibrous waste from the rotary cleaning body according to the present invention will be described below using these drawings.

[0031] The rotating rotor 3 constituting the rotating cleaning body 10 of the present invention is a rod-shaped body with a brush base 2b provided in the longitudinal direction of the rotor body 2, for inserting and fixing one or more cleaning bodies 1 with openings on the outer periphery, and is twisted around the axis so that the twisting directions are opposite from approximately the center of the longitudinal direction of the rotor body 2 to both ends, and the cleaning bodies 1 inserted and fixed in the brush base 2b are arranged so that they are approximately symmetrical with respect to the turning point approximately at the center of the longitudinal direction of the rotor body 2. As a result, fiber waste A scraped by the cleaning body 1 is transferred to both ends of the rotating rotor 3 and stored in the fiber waste storage section 6 of the fiber waste storage body 5, as shown in Figure 5(a).

[0032] Next, as shown in Figure 5(b), the bearing body 7a is removed from the rotary cleaning body 10, and then the fiber waste container 5 is removed from the rotary cleaning body 10. Next, as shown in Figure 5(c), the removed fiber waste container 5 is separated into the flange body 5a and the fitting body 5b, and the fiber waste A is discarded.

[0033] Fig. 6(a) is an enlarged perspective view of a portion of the rotary cleaning body, and Fig. 6(b) is an enlarged exploded perspective view of a portion of the rotary cleaning body. As shown in these figures, the fiber waste storage section 6 of the fiber waste storage body 5 is made up of a groove 6 having a substantially concave axial cross section, and the outer peripheral surface 5d on the rotor body 2 side adjacent to the groove 6 of the fiber waste storage body 5 is formed substantially flush with the outer peripheral surface 2a of the rotor body 2. This makes it easier for the cleaning body 1 to fall toward the fiber waste storage section 6, and since there is no step between it and the fiber waste storage section 6, it is easier to store fiber waste in the fiber waste storage section 6.

[0034] The rotor body 2 has a plurality of brush bases 2b, 2b... formed on its outer circumferential surface 2a from one end to the other in the longitudinal direction, on which cleaning bodies are attached, and a gap 2c is formed between adjacent brush bases 2b, 2b from one end to the other in the longitudinal direction, and a fiber waste discharge port 4b consisting of a notch or hole is formed at a predetermined location of the bracket 4 continuous with the end of the gap 2c. This allows fiber waste, dust, etc. that has accumulated in the gaps 2c between the brush bases 2b, 2b... to be easily discharged to the outside through the fiber waste discharge port 4b, making maintenance of the rotating cleaning body 10 easy.

[0035] The cleaning body 1 has a substantially plate-shaped base 1a and a scraping part 1b extending substantially perpendicularly from the side of the base 1a, with one longitudinal end of the cleaning body 1 extending to the vicinity of the fiber waste storage section 6 of the fiber waste storage body 5, and is positioned so that a part of the scraping part 1b can swing up to the fiber waste storage section 6 when the rotating cleaning body 10 rotates. This makes it easier to transfer fiber waste adhering to the scraping part 1b of the cleaning body 1 to the fiber waste storage section 6.

[0036] 7 is a perspective view showing another embodiment of the rotary cleaning body according to the present invention. In the rotary cleaning body 20, one end of the cleaning body 21 is fixed to the fiber waste container 25, and the cleaning body 21 is detachable from the rotor body 22 and bracket 24 together with the fiber waste container 25. This allows for the simultaneous disposal of fiber waste contained in the fiber waste container 26 and fiber waste attached to the cleaning body 21, facilitating easy maintenance of the rotary cleaning body 20. The cleaning body 21 and the fiber waste container 25 are fixed so that they can be disassembled, and when the cleaning body 21 wears out due to wear, fallen fibers, dirt, or the like, the cleaning body 21 can be removed from the fiber waste container 25 and replaced. [Industrial Applicability]
