It should be noted that the displacement distance in the rotation direction (circumferential direction) of the traveling wheel body 45 between the position of the raised portions 48b of each row C and the raised portions 48b of the row C adjacent to the row C is the rotational direction (circumferential direction) of the traveling wheel body 45. In this embodiment, the length is set to be smaller than half the length of the raised hair 48b along the rotation direction (circumferential direction) of the traveling wheel body 45. The raised portions 48b are arranged at positions separated from the side portions 48a1 and 48a1 and the side portions 48a2 and 48a2 of the base portion 48a, and are not arranged at positions near the side portions 48a1 and 48a1 and the side portions 48a2 and 48a2. .

  Next, the operation of the first embodiment will be described.

  When the raised cloth 48 is manufactured, the raised cloth body 49 shown in FIG. 3 (a) is raised along the cutting line L corresponding to the required size as shown in FIG. 3 (b). Cut out 48. At this time, the raised portion 48ba, which is generated at the positions of the side portions 48a1 and 48a1 and the side portions 48a2 and 48a2 of the base portion 48a, is opened or welded to the base portion 48a as shown in FIG. 3 (c). In addition, at the positions of the side portions 48a1 and 48a1 and the side portions 48a2 and 48a2, which are the end portions of the base portion 48a, there is no raised hair that is open on one side.

  When the traveling wheel 33 shown in FIGS. 1 (a) and 1 (b) is manufactured, the base 48a of the brushed fabric 48 formed above is wound around and adhered to the traveling wheel main body 45 formed in advance. The sleeve 46 formed in advance is inserted into both ends of the insertion hole 45a of the traveling wheel main body 45 so that the side of the base 48a of the raised cloth 48 is between each fixed flange 46a and both ends of the traveling wheel main body 45. The traveling wheels 33 are completed by sandwiching the portions 48a1 and 48a1 and pressing the previously formed rotating shaft 47 over the insertion holes of the sleeves 46 and the insertion holes 45a of the traveling wheel main body 45.

  The traveling wheel 33 manufactured in this way is used for the floor brush 23 by pivotally supporting both ends of the rotation shaft 47 in the notch opening 42 of the case body 31 so as to be rotatable.

  As shown in FIGS. 1 to 5, when cleaning, the connecting pipe portion 26 of the hose body 21 is connected to the main body suction port 19 of the cleaner body 12, and the hand operating portion 27 of the hose body 21 is connected. An extension pipe 22 is connected, and a connection pipe 34 of a floor brush 23 is connected to the extension pipe 22. As a result, the floor brush 23 is communicatively connected to the suction side of the electric blower 18 (through the extension pipe 22, the hose body 21, the main body suction port 19 and the dust collecting portion).

  Then, after connecting the power cord to an outlet such as a wall surface, the operator holds the grip portion 28 and operates the desired setting button 29 to set the electric blower 18 in a desired operation mode via the main body control portion. Start with. By driving the electric blower 18, negative pressure sequentially acts on the dust collecting portion, the main body suction port 19, the hose body 21, the extension pipe 22, and the floor brush 23. Then, the operator places the floor brush 23 on the floor surface and travels forward and backward by the traveling wheel portions 32 and 32 and the traveling wheel 33, thereby sucking dust together with air from the suction port 37. At this time, particularly in the traveling wheel 33, the raised surface 48b of the soft raised cloth 48 contacts the floor surface to prevent the floor surface from being damaged. In addition, the raised hairs 48b that come into contact with the floor surface are each looped along the rotational direction (circumferential direction) of the traveling wheel 33 (the traveling wheel main body 45). Or, it does not catch and wrap linear dust such as lint.

  Dust sucked together with air from the suction port 37 is sucked into the dust collecting part through the connecting pipe 34, the extension pipe 22, the hose body 21, and the main body suction port 19, and separated and collected in the dust collecting part. In addition, the air in which the dust is collected is sucked into the electric blower 18, and after cooling the electric blower 18, the air is exhausted to become exhaust air, and is exhausted to the outside of the cleaner body 12.

  As described above, according to the first embodiment, the raised portions 48b are arranged in a plurality of rows in the axial direction of the traveling wheel main body 45, and the arrangement of the raised portions 48b in each row C is arranged in the rotational direction of the running wheel main body 45. By gradually shifting, the raised portions 48b are arranged in an inclined manner with respect to the axial direction of the traveling wheel 33 (the traveling wheel main body 45). Therefore, when the raised cloth 48 comes into contact with the floor surface and the traveling wheel 33 (traveling wheel main body 45) rotates, the raised portions 48b and 48b in each row C simultaneously face the floor surface in a plurality of rows C adjacent to each other. In other words, when the raised portions 48b, 48b of one row C face the floor surface, the raised portions 48b, 48b of other rows C adjacent to this one row C face the floor surface. Therefore, linear dust such as bristles or lint does not easily enter between the raised hairs 48b and 48b of the plurality of rows C at the same time, and dust does not easily adhere to the raised fabric 48.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the second embodiment, each raised portion 48b of the raised cloth 48 of the first embodiment has an even-numbered raised portion 48b and an even-numbered raised portion 48b from the one end side (the other end side) of the traveling wheel body 45 with respect to the base portion 48a. The raised hairs 48b in the row are planted by shifting in the rotation direction (circumferential direction) of the traveling wheel main body 45.

  In the present embodiment, the raised hairs 48b in the odd-numbered rows C1 and the raised hairs 48b in the even-numbered rows C2 are displaced from each other by approximately half along the rotational direction (circumferential direction) of the traveling wheel body 45, for example. In other words, when the traveling wheel 33 is viewed from the axial direction, the end portions of the raised hairs 48b in the even-numbered rows C2 are located at substantially intermediate positions of both end portions of the raised hairs 48b in the odd-numbered rows C1. Further, when the traveling wheels 33 are viewed from the axial direction, the raised portions 48b of the odd-numbered rows C1 overlap each other. Similarly, when the traveling wheels 33 are viewed from the axial direction, the raised hairs 48b in each even-numbered row C2 overlap each other.

  Then, according to the second embodiment, the raised hairs 48b are arranged in a plurality of rows in the axial direction of the running wheel main body 45, and the raised hairs 48b in the odd rows and the raised hairs 48b in the even rows from the one end side of the running wheel main body 45. Is shifted in the rotational direction of the traveling wheel main body 45, so that the raised portions 48b are arranged in a zigzag shape with respect to the axial direction of the traveling wheel 33 (the traveling wheel main body 45). Therefore, when the raised cloth 48 comes into contact with the floor surface and the running wheel 33 (running wheel main body 45) rotates, between the raised 48b and 48b in the odd-numbered row C1 and between the raised 48b and 48b in the even-numbered row C2. Are not simultaneously facing the floor surface, so that linear dust such as hair or lint is difficult to enter between the raised portions 48b and 48b of the plurality of rows C1 and C2 at the same time. Becomes difficult to adhere.

  As described above, according to at least one embodiment described above, the raised surface 48a is configured by arranging a plurality of raised portions 48b in a loop shape on the base portion 48a attached to the outer periphery of the traveling wheel main body 45. It is difficult to catch linear dust such as bristles or lint scattered on the top, and adhesion of these linear dust to the raised cloth 48 can be suppressed. Therefore, the linear dust can be prevented from being wound around the rotation shaft 47 of the traveling wheel 33 by the rotation of the traveling wheel 33 (the traveling wheel main body 45), and the locking of the traveling wheel 33 due to the winding of the dust can be suppressed. The traveling performance by the traveling wheels 33 can be ensured.

  In addition, the raised fabric 48 has a raised portion 48 on the end portion of the base portion 48a so that the raised portion 48 of the raised portion 48 does not exist at the end portions of the base portion 48a (side portions 48a1, 48a1 and side portions 48a2, 48a2). It can prevent fraying at the position.

  Specifically, the raised cloth 48 is formed by welding or press-bonding a raised 48ba located at one end of the base portion 48a (side portions 48a1, 48a1 and side portions 48a2, 48a2) to the base portion 48a. It is possible to make sure that the raised hairs that are open are not present at the end of the base 48a.

  Furthermore, since the raised portions 48b are densely arranged on the base portion 48a, it is difficult for linear dust to enter the roots of the raised portions 48b, and the entanglement of the raised fabric 48 (the running wheel 33) can be more reliably suppressed.

  By providing such a traveling wheel 33 on the floor brush 23, it is possible to ensure the traveling performance of the floor brush 23 during cleaning, and it is not necessary to perform maintenance such as removing dust entangled with the traveling wheel 33. improves.

  In addition, by using the floor brush 23 with the traveling wheels 33 for the vacuum cleaner 11, the floor brush 23 can be reliably run even on a dusty floor surface, particularly before the start of cleaning. Cleanliness can be obtained, and dust can be prevented from adhering to the traveling wheel 33, so that the amount of dust that becomes entangled with the traveling wheel 33 and cannot be sucked from the suction port 37 is reduced. Can be removed more effectively.

  In each of the above embodiments, for example, the traveling wheel portions 32 and 32 may have the same configuration as the traveling wheel 33.

  Further, any number of the vacuum cleaner wheels can be arranged at any position on the lower surface of the case body 31 of the floor brush 23.

  Further, the raised 48b has a loop shape along the rotational direction (circumferential direction) of the traveling wheel 33 (traveling wheel main body 45) .For example, the raised brush 48b has a loop shape along the axial direction of the traveling wheel 33 (traveling wheel main body 45). Alternatively, the traveling wheel 33 (the traveling wheel main body 45) may be formed in a loop shape inclined with respect to the rotation direction (circumferential direction) or the axial direction.

  And although it was set as the structure which supplies electric power with commercial AC power supply with respect to the electric blower 18, a main body control part, etc., the structure built in the cleaner main body 12 as a power supply part, for example may be sufficient.

  The floor brush 23 can also be applied to, for example, a so-called upright type vacuum cleaner in which a connecting pipe 34 is connected to a lower portion of a vacuum cleaner body that is vertically long.

  Furthermore, the vacuum cleaner wheel is provided not only on the floor brush 23 but also on, for example, a swivel wheel provided in a main body of a canister type vacuum cleaner or a main body of a vacuum cleaner of a self-propelled electric vacuum cleaner. The present invention can also be applied to a traveling wheel on the floor such as a turning wheel or a driven wheel.

  And although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
