A presser wheel 36 is provided on the upper portion of the belt 32. Further, a rotary dial 37 is provided at one end of the wall body 4, and the wall body 4 rotates by rotating the rotary dial 37. In addition, four equally spaced holes 29 are formed on the outer peripheral surface of the rotary dial 37. Furthermore, the outer peripheral surface of the rotary dial 37 is provided with a notch 49 to which the lower lid 10 and the upper lid 19 are attached. In addition, as a method of rotational movement of the wall body 4, a method using a lever or the like may be used in addition to the method as described above.

  As shown in FIG. 3, the rotary cleaning body 2 includes a rotary brush 3 and a wall body 4.

  The rotary brush 3 is made of a metal material such as aluminum, and is provided with a rotor 6 provided so as to open the four groove portions 7 to the outer side evenly in the longitudinal direction of the outer peripheral surface. It consists of a body 5. The cross-sectional shape of the groove portion 7 is a constant substantially ridge shape over the entire length of the rotor 6 and is formed so that the outer peripheral opening becomes narrower toward the inside. Further, the groove portion 7 and the cleaning body 5 constituting the rotating brush 3 are formed in a spiral shape in which a twist is applied around the longitudinal axis of the rotor 6. In addition, the rotor 6 is manufactured by extruding it straight and then twisting it around the longitudinal axis of the rotor 6. In addition, as a method for manufacturing the rotor 6, a method in which a metal material such as aluminum is formed in a straight straight shape by extrusion molding can be used. In addition to the above, the method of manufacturing the rotor 6 includes a method of forming a predetermined spiral shape at a time by twist extrusion molding. Furthermore, if it is a synthetic resin, you may complete the rotor 6 by injection molding. As a material of the rotor 6, in addition to a metal material such as aluminum, a synthetic resin, a rubber-based elastomer, wood, or the like can be appropriately selected. Regarding the manufacturing method, regardless of the above method, any method can be used as long as it can complete the target shape. Further, in the present embodiment, the rotor 6 is described in a spiral shape, but, of course, it may be used without being twisted. The cleaning body 5 is not particularly limited in material and shape, such as filaments such as nylon and polyester, rubber-based elastomers, soft materials such as synthetic resin foams, fabrics, etc. Can be set in a timely manner.

  The wall body 4 has a substantially right-angle shape, and is made of a metal material such as aluminum, a synthetic resin material such as polyolefin, paper, or the like, and has a fabric 8 formed on the surface and holes 9 formed on both ends. is there. The material and shape of the fabric 8 such as a woven fabric, a nonwoven fabric, and a knitted fabric are not particularly limited, and can be set as appropriate according to the purpose of use. In addition, the method of forming the fabric 8 on the surface of the wall body 4 may be bonding, welding, screwing, or the like, but is not limited to the above-described forming method, and can be set as appropriate. The wall 4 is provided with a vent hole 47 for removing dust wiped off by the fabric 8. The shape of the ventilation hole 47 is not particularly limited, and can be set as appropriate.

  Further, instead of the fabric 8, any material that does not damage the surface to be cleaned, such as a soft material such as a rubber-based elastomer or a synthetic resin foam, tissue paper, or the like can be used without any problem. Further, the wall body 4 may be used by forming the surface of the wall body 4 with silicone processing, fluorine processing, or the like without forming the fabric 8 or the like as described above on the surface of the wall body 4.

  Next, assembly of the rotary cleaning body 2 will be described. The wall 4 is set to be positioned in the vicinity of the outer peripheral surface of the rotating brush 3 by inserting both ends of the rotating brush 3 into the hole 9. One end of the rotor 6 constituting the rotary brush 3 is provided with a rotary bearing 34 that is a ball bearing-type rolling bearing that is press-fitted. The rotary bearing 34 is inserted into one end of a bearing 35. Then, the convex portion 38 provided at one end of the bearing 35 is inserted into the concave portion 39 provided at one end of the wall body 4, and the rotary dial 37 is put on the bearing 35. On the other hand, a rotary bearing 34 to be press-fitted is provided at the other end of the rotor 6. The rotary bearing 34 is inserted into one end of a bearing 35, and is further press-fitted and a belt 32 driven by a motor 31 is stretched. A pulley-equipped bearing 33 is provided. And the convex part 38 provided in the end of the bearing 35 is inserted in the recessed part 39 (not shown) provided in the end of the wall body 4, the rotary brush 3 and the wall body 4 are integrated, and rotational cleaning is carried out. Configured as body 2. Then, the rotary cleaning body 2 has the lower lid 10 and the upper lid 19 attached to and sandwiched by a notch 49 provided on the outer peripheral surface of the rotary dial 37 attached to one end of the wall body 4. It is assembled to the floor nozzle 1 for a vacuum cleaner. The other end of the rotary cleaning body 2 is supported by a bearing 33 with a pulley that is press-fitted into the rotor 6 constituting the rotary brush 3, and is stretched around a motor 31 via a belt 32.

  Next, with reference to FIG. 4A and FIG. 4B, rotation of the rotating brush 3 and the wall body 4 constituting the rotary cleaning body 2 of the floor nozzle 1 for a cleaner in the embodiment of the present invention. Explain the mechanism. The wall body 4 is set with a position of contact with the surface to be cleaned by rotating the rotary dial 37. That is, the outer peripheral surface of the rotary dial 37 is provided with four equally-divided hole portions 29, and a ball plunger (not shown) set on the lower lid 10 moves along with the rotation of the rotary dial 37. Then, it is inserted into the hole 29 and positioned and fixed. Therefore, the wall body 4 can be rotated and rotated every 90 ° by rotating the rotary dial 37 clockwise or counterclockwise, and the position of contact with the surface to be cleaned can be set. In addition to the method described above, the same positioning as described above may be performed using a ratchet mechanism or the like. In addition, the wall body 4 is provided with a lower lid 10 and an upper lid 19 attached to a notch 49 provided on an outer peripheral surface of a rotary dial 37 attached to one end, and sandwiched between them, and a floor nozzle for a vacuum cleaner. Therefore, X1 which is the center line of the rotation of the wall body 4 is always constant even when the wall body 4 rotates and is the same as X6 which is the center point of the bearing 35 and the rotary dial 37. It is one point above. On the other hand, in the rotating brush 3, as described above, the rotating bearings 34 press-fitted into both ends of the rotor 6 are inserted into the bearings 35. Y6, which is the center point of the inner periphery of the bearing 35 and the center point of the rotary bearing 34, is at a position deviated by 45 ° from X6, which is the center point of the outer periphery of the bearing 35, as shown in FIG. For this reason, the center point Y6 of the rotation bearing 34 that coincides with the rotation center point of the rotary brush 3 and the center point X6 of the bearing 35 that coincides with the rotation center point of the wall body 4 are not at the same position. Although the rotary brush 3 and the wall body 4 are integrated, the rotation center line Y1 of the rotation brush 3 can be set at a position different from the rotation center line X1 of the wall body 4. Further, since the rotating brush 3 is integrated with the wall body 4, when the wall body 4 rotates and moves every 90 °, the rotation center point Y6 of the rotation brush 3 becomes the rotation center point X6 of the wall body 4. Rotate and move every 90 ° around the center. The outer peripheral surface of the rotary bearing 34 is fixed in contact with the inner wall surface of the inserted bearing 35. As described above, the rotor 6 is press-fitted with a bearing 33 with a pulley and a rotary bearing 34 that is a ball bearing-shaped rolling bearing. Therefore, the rotating brush 3 is driven to rotate freely around the center line Y1 of rotation of the rotating brush 3 when the motor 31 is driven. As described above, since the belt 32 is pressed by the presser wheel 36 provided on the upper portion of the belt 32, the parallelism with respect to the surface to be cleaned of the rotary brush 3 is maintained. By the mechanism as described above, the rotation center line Y1 of the rotary brush 3 and the rotation center line X1 of the wall body 4 can be present at different positions rather than on the same line. Even if they are integrated, they can be brought into contact with the surface to be cleaned at the same time.

  Next, using FIG. 5 (a), FIG. 5 (b), and FIG. 5 (c), a rotary brush 3 constituting the rotary cleaning body 2 of the floor nozzle 1 for a cleaner in the embodiment of the present invention, The contact state of the wall 4 with the surface to be cleaned and the mechanism for removing dust adhering to the surface to be cleaned will be described. As shown in FIGS. 5A and 5B, in the rotating brush 3, the cleaning body 5 is in contact with a horizontal surface such as a carpet, tatami mat, floor, and the wall body 4 is in contact with a vertical surface such as a wall. It is set as follows. That is, as shown in FIG. 5C, when the height of one side of the wall body 4 on which the fabric 8 is formed is x2, X2 which is the center point of the rotation of the wall body 4 has a side length of x2. It coincides with the intersection of the diagonals of the virtual square. Further, Y2 which is the center point of rotation of the rotating brush 3 is on the diagonal of the virtual square whose side is x2, and is located behind 45 ° obliquely below the center point X2 of rotation of the wall 4. Therefore, since the rotation center point X2 of the wall body 4 and the rotation center point Y2 of the rotation brush 3 exist at different positions, the cleaning body 5 of the rotation brush 3 comes into contact with a horizontal surface such as a carpet, tatami mat, floor, The wall body 4 allows the fabric 8 to contact a vertical surface such as a wall. Therefore, while the rotating brush 3 rotates, the cleaning body 5 scrapes or sweeps off dust adhering to the carpet, tatami mat, floor, etc., and is removed by the suction air of the arrow A in FIG. The fabric 8 formed on the surface of the wall body 4 is wiped in close contact with dust adhering to the wall or the like, and is removed by the suction air indicated by the arrow B in FIG. Therefore, the dust adhering to the horizontal surface and the vertical surface of the surface to be cleaned is simultaneously removed by the rotary cleaning body 2 of the floor nozzle 1 for the cleaner.

  Next, with reference to FIG. 6A and FIG. 6B, the rotating brush 13 and the wall body 14 constituting the rotating cleaning body 12 of the floor nozzle 11 for a cleaner according to another embodiment of the present invention. The contact state with respect to the surface to be cleaned and the mechanism for removing dust adhering to the surface to be cleaned will be described. As shown in FIG. 6A, the wall body 14 is set so that the cloth 18 is in contact with a horizontal surface such as a carpet, tatami mat, floor, and the rotary brush 13 is in contact with a vertical surface such as a wall. That is, as shown in FIG. 6B, if the height of one side of the wall body 14 on which the fabric 18 is formed is x3, X3 which is the center point of the rotation of the wall body 14 has a side length of x3. It coincides with the intersection of the diagonals of the virtual square. Moreover, Y3 which is the rotation center point of the rotary brush 13 is on the diagonal of the virtual square whose side length is x3, and is positioned 45 ° obliquely forward from the rotation center point X3 of the wall 14. Therefore, since the rotation center point X3 of the wall body 14 and the rotation center point Y3 of the rotation brush 13 are present at different positions, the wall body 14 rotates when the fabric 18 is in contact with a horizontal surface such as a carpet, tatami mat, or floor. The brush 13 allows the cleaning body 15 to contact a vertical surface such as a wall. Therefore, the cloth 18 formed on the surface of the wall body 14 wipes off dust adhering to the carpet, tatami mat, floor, etc., and is removed by the suction air of the arrow C in FIG. While rotating, the cleaning body 15 scrapes or sweeps off dust adhering to the wall or the like, and is removed by the suction air indicated by the arrow D in FIG. Therefore, the dust adhering to the horizontal surface and the vertical surface of the surface to be cleaned is simultaneously removed by the rotary cleaning body 12 of the floor nozzle 11 for the cleaner.

  Next, with reference to FIG. 7A and FIG. 7B, a rotating brush 23 and a wall body 24 that constitute the rotating cleaning body 22 of the floor nozzle 21 for a cleaner in another embodiment of the present invention. The contact state with respect to the surface to be cleaned and the mechanism for removing dust adhering to the surface to be cleaned will be described. As shown in FIG. 7A, the rotary brush 23 has the cleaning body 25 in contact with a horizontal surface such as a carpet, tatami mat, and floor, and a vertical surface such as a wall, and the wall body 24 is stored inside the floor nozzle 21 for the cleaner. The fabric 28 is set so as not to contact the surface to be cleaned. That is, as shown in FIG. 7B, when the height of one side of the wall body 24 on which the fabric 28 is formed is x4, X4 which is the center point of the rotation of the wall body 24 has a side length of x4. It coincides with the intersection of the diagonals of the virtual square. Further, Y4, which is the rotation center point of the rotary brush 23, is on the diagonal of a virtual square whose side length is x4, and is positioned forward 45 ° obliquely below the rotation center point X4 of the wall body 24. Therefore, since the rotation center point X4 of the wall body 24 and the rotation center point Y4 of the rotation brush 23 exist at different positions, the cleaning body 25 of the rotation brush 23 has a horizontal surface such as a carpet, a tatami mat, a floor, and a wall. The wall body 24 is stored inside the floor nozzle 21 for the cleaner, and the fabric 28 can be set so as not to contact the surface to be cleaned. Therefore, while the rotating brush 23 rotates, the cleaning body 25 scrapes or sweeps off dust adhering to the carpet, tatami mat, floor, etc., and is removed by the suction air of arrow E in FIG. At the same time, the dust adhering to the wall or the like is scraped or swept away and removed by the suction air indicated by the arrow F in FIG. Therefore, the dust adhering to the horizontal surface and the vertical surface of the surface to be cleaned is simultaneously removed by the rotary cleaning body 22 of the floor nozzle 21 for the cleaner.

  Next, with FIG. 8A and FIG. 8B, the object to be cleaned by the rotating brush 53 and the wall body 54 constituting the rotating cleaning body 52 of the floor nozzle 51 for a cleaner in another embodiment. A mechanism for removing dust adhering to the surface will be described. As shown in FIG. 8A, the wall body 54 has a cloth 58 in contact with a horizontal surface such as a carpet, a tatami mat, and a floor, and a vertical surface such as a wall, and the rotating brush 53 is stored inside the floor nozzle 51 for a vacuum cleaner. The cleaning body 55 is set so as not to contact the surface to be cleaned.
