  Incidentally, a ceiling fan that circulates indoor air and enhances the air conditioning efficiency in addition to the fluorescent tube is often suspended from the ceiling on which the above-described fluorescent tube is attached as a lighting fixture. In recent years, ceiling fans integrated with lighting fixtures have been widely used. In this regard, in the fluorescent tube cleaning tool having the above-described configuration, the opposing wall having the suction port is disposed below the cleaning target, and the opposing wall having no suction port is disposed above the cleaning target. For example, it is possible to clean the rotor blades of a ceiling fan.

  However, as described above, the suction port for sucking dust is formed only on the opposing wall disposed below the rotor blade. Therefore, although dust scattered on the lower side of the rotor blade can be efficiently collected by the suction port, it is difficult to collect dust scattered on the upper side of the rotor blade by the suction port. Moreover, more dust is usually accumulated on the upper side of the rotor blade than on the lower side of the rotor blade. Therefore, each time the ceiling fan is cleaned, a lot of dust that is not collected at the suction port falls off the ceiling fan.

  This invention is made | formed in view of such a situation, and it aims at providing the cleaning tool for ceiling fans which can suppress that dust dances at the time of cleaning of a ceiling fan.

The cleaning tool for a ceiling fan in the present invention is a cleaning tool for a sealing fan that is connected to a suction pipe of a vacuum cleaner and cleans the ceiling fan by the suction force of the vacuum cleaner, with the rotor blades of the ceiling fan interposed therebetween. A pair of hollow arms facing each other, and a hollow connecting portion that connects at least one of the pair of hollow arms and the suction pipe, each of the pair of hollow arms is connected to communicate with each other; The connecting portion communicates each of the pair of hollow arms with the suction pipe, and each of the pair of hollow arms has a portion facing the other hollow arm, the inside of the hollow arm, and the hollow tube. is formed with suction holes and a brush for communicating the outside of the arms, in the pair of hollow arms, rotatable one of said hollow arms to the other of said hollow arms It is summarized as being connected.

According to the present invention, the pair of main surfaces facing each other in the rotor blades are wiped by the pair of hollow arm brushes. Moreover, since the internal space of each of the pair of hollow arms communicates with the suction pipe of the vacuum cleaner, in each of the pair of hollow arms, most of the dust removed by wiping the hollow arms is sucked by the hollow arms. Dust is collected in the hole. That is, dust is sucked from two directions facing each other with respect to the rotating blades of the ceiling fan. Therefore, it is possible to prevent dust from flying during cleaning of the ceiling fan, as compared with the case where dust is sucked from one direction with respect to the rotor blades of the ceiling fan.
In addition, since the angle formed by one hollow arm and the other hollow arm changes, after the pair of hollow arms are brought close to the rotor blade in a state where the angle formed by these is large, the angle formed by the rotor arm is decreased to reduce the angle between the rotor blades. Can be sandwiched between a pair of hollow arms. Therefore, it becomes easy to arrange | position a pair of hollow arm according to the shape and arrangement | positioning of a rotary blade. In addition, since dust can be sucked from each hollow arm in a state where the angle formed by the pair of hollow arms is large, it is possible to clean a portion other than the rotor blades.

  In the cleaning tool for a ceiling fan according to the present invention, the pair of hollow arms includes a first hollow arm to which the connecting portion is connected and a second hollow arm to which the connecting portion is not connected. The hollow arm communicates with the second hollow arm in a state where the pair of hollow arms face each other, and an angle formed by the pair of hollow arms is increased from the state. It is desirable that a communication port that is blocked by the hollow arm is formed.

  According to the present invention, the angle formed by the pair of hollow arms is increased, so that the communication between the pair of hollow arms is blocked, whereby dust is sucked from only one hollow arm. Therefore, when the ceiling fan is cleaned only by one hollow arm, the suction force of the vacuum cleaner is not wasted in the other hollow arm.

In the sealing fan cleaning tool according to the present invention, it is desirable that the connecting portion is rotatably connected to one of the pair of hollow arms.
According to this invention, even if the suction pipe and the connecting portion are fixed, the pair of hollow arms rotate with respect to them. In a state where one hollow arm is fixed to the suction pipe and the connecting part, it is necessary to change the arrangement of the suction pipe and the connecting part in order to match the arrangement of the pair of hollow arms to the shape of the object to be cleaned. In this regard, with the configuration described above, the frequency of changing the arrangement of the suction pipe and the connecting portion is reduced by the amount of rotation of the connecting portion with respect to the pair of hollow arms. Therefore, it is possible to reduce the load required for cleaning the ceiling fan.

  In the cleaning tool for a ceiling fan according to the present invention, the connecting portion includes a first connecting pipe rotatably connected to one of the pair of hollow arms via a first rotating shaft, and the first rotating shaft. It is desirable to provide a second connecting pipe rotatably connected to the first connecting pipe via a second rotating shaft that intersects.

  According to the present invention, the suction tube can be rotated with respect to the pair of hollow arms around the first rotating shaft and the second rotating shaft that intersect each other. Therefore, the frequency of changing the arrangement of the suction pipes is reduced by the amount of rotation of the suction pipes by the two rotating shafts intersecting each other with respect to the pair of hollow arms. Therefore, it is possible to reduce the load required for cleaning the ceiling fan.

  According to such a configuration, at the upper end portion of the handle 11, the rotary connecting tube 13 rotates about the tube rotation shaft 11A extending in the left-right direction. At this time, in a range in which the stopper 11S can move in the guide hole 13C, the rotary connecting tube 13 rotates with respect to the handle 11, and the stopper 11S comes into contact with the guide hole 13C, so that the rotating connecting tube 13 rotates. Be regulated.

(Wiping unit 12)
As shown in FIG. 4, the wiping portion 12 includes a first hollow arm 21 and a second hollow arm 22 that are a pair of hollow arms facing each other.

  The first hollow arm 21 is formed in a rectangular tube extending in the front-rear direction, and is bent downward in the vertical direction at the end of the rotary connecting tube 13 side. At the end of the first hollow arm 21 on the rotary connecting tube 13 side, a hollow arm rotating shaft 21A inserted as a first rotating shaft into the connecting hole 13A of the rotating connecting tube 13 faces the rotating connecting tube 13 side.

That is, at the distal end portion of the handle 11, the wiping portion 12 rotates around the tube rotation shaft 11A extending in the left-right direction and the arm rotation shaft 21A extending in the front-rear direction. And while the wiping part 12 rotates three-dimensionally, the internal space of the handle 11 and the internal space of the wiping part 12 continue to communicate with each other. In addition, since the protrusion which protrudes to an outer side of radial direction is protrudingly provided in the surrounding wall which comprises the arm rotating shaft 21A, such a connection with the wiping part 12 and the rotation connection pipe | tube 13 will be ensured.

(First hollow arm 21)
As shown in FIG. 5 (a), the first hollow arm 21 is a hollow columnar member bent in an L shape, and includes a bent portion 21B connected to the rotary connecting tube 13, and the bent portion 21B. The upper wiping cylinder 21T extends forward. Of the side surfaces constituting the first hollow arm 21, the upper wiping surface 21F, which is the side surface facing the second hollow arm 22, has a brush Br1 implanted at the center in the left-right direction over the entire width in the front-rear direction. Has been. The upper wiping surface 21F has a plurality of suction holes 21H extending through substantially the entire width in the front-rear direction of the bent portion 21B and the upper wiping cylinder 21T so that the brush Br1 is sandwiched from both sides in the left-right direction. According to the arrangement of the brush Br1 and the suction hole 21H, even if the first hollow arm 21 moves in both the left and right directions with respect to the cleaning target such as the rotary blade CF4, the dust removed by the brush Br1 is the brush Br1.

(Second hollow arm 22)
As shown in FIG. 5B, the second hollow arm 22 is a hollow rectangular columnar member extending in the front-rear direction. Of the side surfaces constituting the second hollow arm 22, the lower wiping surface 22F, which is the side surface facing the first hollow arm 21, has a brush Br2 planted in the center in the left-right direction over the entire width in the front-rear direction. It is installed. The lower wiping surface 22F has a plurality of suction holes 22H extending through substantially the entire width in the front-rear direction so that the brush Br2 is sandwiched from both sides in the left-right direction. According to the arrangement of the brush Br2 and the suction hole 22H, even if the second hollow arm 22 moves in both the left and right directions with respect to the cleaning target such as the rotary blade CF4, the dust removed by the brush Br2 is removed. Is sucked by the suction hole 22H adjacent to the right side or the left side. Therefore, the amount of dust falling from the ceiling fan CF can be suppressed.

  In addition, a pair of bearing holes 22C penetrates the left and right side surfaces 22L and 22R facing each other among the side surfaces constituting the second hollow arm 22 so that the centers thereof coincide with each other. In each of these bearing holes 22C, the connecting shaft 21C of the first hollow arm 21 described above is pivotally supported, whereby the first hollow arm 21 and the second hollow arm 22 are connected via a hinge structure. . Further, in each of the left and right side surfaces 22L and 22R, a closed locking hole K1 and an open locking hole K2 smaller than the bearing hole 22C pass through the rear of the bearing hole 22C. These two locking holes K1 and K2 have the same distance from the bearing hole 22C, and are formed in such a size that the above-described locking portion 21K can be fitted. The angle formed between the straight line connecting the bearing hole 22C and the closed locking hole K1 and the straight line connecting the bearing hole 22C and the open locking hole K2 is approximately 90 °.

  In addition, a second arm communication port 22 </ b> D is opened in a portion of each side surface constituting the second hollow arm 22 that faces the bent portion 21 </ b> B of the first hollow arm 21. The second arm communication port 22D communicates with the first hollow arm 21, whereby the pair of hollow arms 21 and 22 communicate with each other.

  And the angle which the 1st hollow arm 21 and the 2nd hollow arm 22 make changes by connecting both the hollow arms 21 and 22 mutually by the hinge structure mentioned above. For example, when the angle formed by the first hollow arm 21 and the second hollow arm 22 is approximately 0 °, as shown in FIG. 2B, the first arm communication port is passed through the second arm communication port 22D. 21D is disposed in the second hollow arm 22. At this time, the locking portion 21K of the first hollow arm 21 is fitted into the closed locking hole K1 of the second hollow arm 22, and thereby the state (closed state) in which the angle formed above is 0 ° is maintained. On the other hand, when an external force is applied to the first hollow arm 21 or the second hollow arm 22 such that the angle formed by the first hollow arm 21 and the second hollow arm 22 is greater than approximately 0 °, the locking portion 21K. Is disengaged from the closed locking hole K1. Then, from the closed state described above, the second hollow arm 22 rotates counterclockwise with respect to the first hollow arm 21, and accordingly, the first arm communication port 21 </ b> D gradually moves away from the second hollow arm 22. Further, when the angle formed between the first hollow arm 21 and the second hollow arm 22 is approximately 90 °, the first arm communication port 21 </ b> D is blocked by the side wall of the second hollow arm 22. That is, when the angle formed by the pair of hollow arms 21 and 22 is increased, the communication between the pair of hollow arms 21 and 22 is interrupted, whereby dust is sucked from only the first hollow arm 21. Become. Therefore, when the ceiling fan CF is cleaned only by the first hollow arm 21, the suction force of the vacuum cleaner CL is not wasted in the second hollow arm 22. At this time, the locking portion 21K of the first hollow arm 21 is fitted into the open locking hole K2 of the second hollow arm 22, and thereby the state (open state) in which the angle formed above is 90 ° is maintained.

  And when cleaning rotary blade CF4, the wiping part 12 is first made into an open state. Next, the lower wiping surface 22F faces the lower surface of the rotor blade CF4, or the upper wiping surface 21F faces the upper surface of the rotor blade CF4. Subsequently, the arrangement of the handle 11 or the rotary connecting pipe 13 is changed so that the wiping unit 12 is closed. When the rotary blade CF4 is sandwiched between the first hollow arm 21 and the second hollow arm 22 in this way, the electric vacuum cleaner CL is driven and the wiping portion 12 extends over the entire longitudinal width of the rotary blade CF4. Are scanned. As a result, the entire upper surface and lower surface of the rotor blade CF4 are wiped by the brush, and during this time, the dust removed from the rotor blade CF4 is sucked from the suction holes 21H and 22H.

As described above, according to the present embodiment, the effects listed below can be obtained.
(1) A pair of main surfaces facing each other in the rotor blade CF4 are wiped by the brushes Br1 and Br2 of the pair of hollow arms 21 and 22. Moreover, since each internal space of a pair of hollow arms 21 and 22 is connected to the hose H of the vacuum cleaner CL, each of the pair of hollow arms 21 and 22 is removed by wiping the hollow arms 21 and 22. Most of the dust is collected in the suction holes 21H and 22H of the hollow arms 21 and 22. That is, dust is sucked into the rotor blade CF4 of the ceiling fan CF from above and below facing each other. Therefore, it is possible to prevent the dust from flying when cleaning the ceiling fan CF, as compared with the case where dust is sucked from one direction with respect to the rotary blade CF4 of the ceiling fan CF.

  (2) Since the angle formed by the first hollow arm 21 and the second hollow arm 22 changes, the pair of hollow arms 21 and 22 are brought close to the rotor blades in a state in which these angles are large, and then the angle formed by these is set. The rotor blade CF4 can be sandwiched between the pair of hollow arms 21 and 22 by reducing the size. Therefore, it becomes easy to arrange | position a pair of hollow arms 21 and 22 according to the shape and arrangement | positioning of rotary blade CF4. In addition, since dust can be sucked from each hollow arm in a state where the angle formed by the pair of hollow arms 21 and 22 is large, it is possible to clean a portion other than the rotary blade CF4.

(3) Further, by cleaning the hinge structure with the hinge structure opened, even the motor CF3 having such a thickness that the wiping portion 12 cannot be clamped can be cleaned.
(4) Since the angle formed by the pair of hollow arms 21 and 22 is increased, the communication between the pair of hollow arms 21 and 22 is interrupted, whereby dust is sucked from only the first hollow arm 21. Become. Therefore, when the ceiling fan CF is cleaned only by the first hollow arm 21, the suction force of the vacuum cleaner CL is not wasted in the second hollow arm 22.

  (5) Even if the hose H, the handle 11 and the rotary connecting pipe 13 are fixed, the pair of hollow arms 21 and 22 rotate with respect to them. Therefore, the frequency of changing the arrangement of the hose H, the handle 11 and the rotary connecting pipe 13 is reduced by the amount of rotation of the pair of hollow arms 21 and 22. Therefore, it is possible to reduce the load required for cleaning the ceiling fan CF.

  (6) The pair of hollow arms 21 and 22 can be rotated with respect to the handle 11 around the tube rotation shaft 11A and the arm rotation shaft 21A intersecting each other. Therefore, the frequency of changing the arrangement of the handle 11 is reduced by the amount of rotation of the pair of hollow arms 21 and 22 on the two rotation axes that intersect with the handle 11. Therefore, it is possible to reduce the load required for cleaning the ceiling fan CF.

In addition, the said embodiment can also be implemented with the following changes.

At that time, it is desirable that the handle 11 and the wiping portion 12 are connected via the arm rotation shaft 21A. If it does in this way, the effect according to said (1)-(5) can be acquired.

  -The width in the left-right direction of the lower wiping surface 22F may be wider than the width in the left-right direction of the upper wiping surface 21F. With such a configuration, the suction hole 22H is formed over a wide range corresponding to the lower wiping surface 22F, and thus the dust removed by the brush Br1 is sufficiently collected by the suction hole 22H. It is possible. Even if it does in this way, the effect according to said (1) can be acquired.

  The brush Br1 may be planted on the entire upper wiping surface 21F, and the brush Br2 may be planted on the entire lower wiping surface 22F. At this time, the suction holes 21H and 22H may be provided so as to be surrounded by the brushes Br1 and Br2. Even if it is such a structure, the effect according to said (1) can be acquired.
