Further, notch recesses 67a into which the shaft portions 45 that pivotally support the bristle brush portion 34 are respectively formed on both side portions of the connection portion 67.

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

  At the time of cleaning, first, as shown in FIG. 5, the dust collecting part is attached to the cleaner body 12 and the connecting pipe part 21 of the hose body 22 is connected to the main body suction port 19.

  For example, when cleaning a wide floor surface using the floor brush 26, the extension pipe 24 and the rotary pipe unit 25 are sequentially connected to the hose body 22, and the floor brush 26 is attached to the tip of the rotary pipe unit 25. Connecting.

  At this time, the fitting portion 42 of the rotary tube unit 25 is inserted from the rear with respect to the connecting portion 67 of the floor brush 26, and the connection between the fitting portion 42 and the connecting portion 67 is held via the holding mechanism. In this state, as shown in FIGS. 2 and 3, the bristle brush portion 34 is positioned around the connection portion 67 and fits into the recess 66, and the mounting portion 33 of the rotary tube unit 25, the rotary tube portion 32, and the main body Each of the portions 31 is located behind (outside) the recess 66. The wheel 44 is positioned behind the notch opening 64 of the floor brush 26, and the lower portion of the wheel 44 is at a height position substantially equal to the lower surface 62 (the raised cloth portion 65) of the case body 61 of the floor brush 26, and The suction port 63 and the cutout opening 64 are connected to the rotary tube unit 25 in an airtight manner through the opening 72, the connection portion 67, and the fitting portion. As a result, the raised cloth 47 of the wheel 44 can come into contact with the floor surface.

  Then, the operator grips the grip portion 28 shown in FIG. 5 and operates a desired setting button 29 to activate the electric blower 18 in a desired operation mode via the main body control portion. By driving the electric blower 18, negative pressure sequentially acts on the dust collecting portion, the main body suction port 19, the hose body 22, the extension pipe 24, the rotary pipe unit 25, and the floor brush 26. Then, the operator places the floor brush 26 on the floor surface and travels forward and backward, thereby sucking dust together with air from the suction port 63 and the notch opening 64. At this time, the wheel 44 (FIG. 2) rotates according to the traveling of the floor brush 26 and assists the traveling, whereby the traveling performance of the floor brush 26 is improved.

  On the other hand, when using the bristle brush portion 34 to clean the floor surface in a narrow gap such as between furniture or the surface to be cleaned S such as a high position, as shown in FIG. By operating, the holding of the connection between the fitting portion 42 and the connection portion 67 is released, and the floor brush 26 is removed from the rotary tube unit 25 side. In this state, the bristle brush portion 34 is pivotably positioned at the most distal portion.

  Then, the operator grips the grip portion 28 shown in FIG. 5 and operates a desired setting button 29 to activate the electric blower 18 in a desired operation mode via the main body control portion. By driving the electric blower 18, negative pressure sequentially acts on the dust collecting portion, the main body suction port 19, the hose body 22, the extension pipe 24, and the rotary pipe unit 25. Then, the operator places the bristle brush portion 34 on the floor surface and runs forward and backward. At this time, when the operator contracts the arm holding the grip portion 28 (when pulling the arm), that is, when the bristle brush portion 34 is positioned relatively close to the worker, FIG. As shown, since the tube portion 13 stands in a state near to the surface to be cleaned S, the bristle brush 52 of the bristle brush portion 34 is in a state of being substantially perpendicular to the surface to be cleaned S. For this reason, the wheel 44 of the rotary tube unit 25 is separated from the surface S to be cleaned. Then, the bristle brush 52 scrapes off dust on the surface S to be cleaned, and the scraped dust and the like are sucked from the rotary tube unit 25.

  When the operator extends the arm holding the grip portion 28 (FIG. 6) (when pressing with the arm), that is, when the bristle brush portion 34 is located at a position relatively far from the worker, FIG. As shown in b), the tube portion 13 lies down (collapses) in a state where the tube portion 13 is inclined with respect to the surface S to be cleaned by a predetermined angle or more. The surface to be cleaned is greatly bent with respect to the surface to be cleaned S and the side surface comes into contact with the surface to be cleaned S. For this reason, the wheel 44 of the rotary tube unit 25 comes relatively close to the surface S to be cleaned, and assists the running of the bristle brush portion 34 on the surface S to be cleaned. Then, the bristle brush 52 scrapes off dust on the surface S to be cleaned, and the scraped dust and the like are sucked from the rotary tube unit 25.

  As described above, the air sucked together with the dust using the floor brush 26 or the bristle brush portion 34 becomes an intake air and sucked into the dust collecting portion through the extension pipe 24, the hose body 22, and the main body suction port 19. And when intake air passes a dust collection part, dust is collected by a dust collection part. After that, the intake air is sucked into the electric blower 18 and passes through while cooling the inside of the electric blower 18 to become exhaust air, from the exhaust hole formed in the main body case 15 to the outside of the cleaner main body 12. Exhausted.

  Thus, when cleaning using the bristle brush part 34, at least the rotary tube unit 25 is removed from the floor brush 26 and a part of the bristle brush part 34 is in contact with the surface to be cleaned S, the wheel 44 is Since it contacts with the surface to be cleaned S, the contact load with the surface to be cleaned S such as a carpet can be reduced.

  As a result, the operation load at the time of cleaning using the bristle brush portion 34 is reduced, the operability is improved, and the cleaning property is improved.

  Further, the rotary tube unit 25 (tube portion 13) is at a predetermined angle with respect to the surface to be cleaned S in a state where the rotary tube unit 25 is removed from the floor brush 26 and the bristle brush portion 34 is in contact with the surface S to be cleaned. When inclined as described above, the bristle brush 52 of the bristle brush portion 34 also lies on the surface to be cleaned S, so that the contact area between the bristle brush 52 and the surface to be cleaned S is relatively large, and the contact load is relatively increased. . Therefore, when the rotary tube unit 25 (tube portion 13) is inclined at a predetermined angle or more with respect to the surface to be cleaned S in this way, the wheel 44 contacts the surface to be cleaned S, thereby reducing the contact load. Even if the rotary tube unit 25 (tube portion 13) is inclined with respect to the surface to be cleaned S by a predetermined angle or more, the operation load can be reduced effectively.

  Further, since the wheel 44 contacts the surface to be cleaned S in a state where the rotary tube unit 25 is connected to the floor brush 26 and the floor brush 26 is in contact with the surface S to be cleaned, the wheel for the floor brush 26 is There is no need to provide them separately, and the number of parts can be reduced by sharing the configuration.

  Further, by forming the outer peripheral portion of the wheel 44 that can contact the surface to be cleaned S with a soft member, specifically, a raised cloth 47, the impact sound when the wheel 44 contacts the surface to be cleaned S can be reduced. The surface 44 can be prevented from being damaged by the wheels 44. In addition, since the bristles of the raised cloth 47 face sideways with respect to the rotation direction of the wheel 44, the contact load between the surface to be cleaned S and the wheel 44 does not increase.

  Next, a second embodiment will be described with reference to FIGS. 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, instead of the wheel 44 of the first embodiment, spherical bodies 75 and 75 as rotating bodies are provided.

  These spheres 75 and 75 are formed of, for example, a flexible member having flexibility and elasticity, and as shown in FIGS. 6 to 8, the horizontal width direction is continuous between the support portions 43 and 43 of the mounting portion 33. Further, they are attached to a spherical body receiving portion 77 as a longitudinal rotating body receiving portion so as to be spaced apart from each other in the left-right width direction and rotatable in an arbitrary direction. In addition, these spheres 75, 75 protrude downward from the sphere receiving portion 77 only at a portion below the center position. Further, these spheres 75, 75 can contact the floor surface with the rotary tube unit 25 and the floor brush 26 connected, and the rotary tube unit 25 is removed from the floor brush 26 and cleaned using the bristle brush portion 34. In doing so, the cleaning surface S is configured to be in contact with or separated from the cleaning surface S according to the angle of the main body 31 (extension pipe 24).

  When the bristle brush portion 34 is used to clean the floor surface in a narrow gap such as between furniture or the surface to be cleaned S such as a high position, the fitting mechanism 42 is operated by operating the holding mechanism. And the connection between the connection portion 67 is released, and the floor brush 26 is removed from the rotary tube unit 25 side. In this state, the bristle brush portion 34 is pivotably positioned at the most distal portion.

  Then, when cleaning using the floor brush 26, the fitting portion 42 of the rotary tube unit 25 is inserted from the rear with respect to the connection portion 67 of the floor brush 26, and the fitting portion 42 via the holding mechanism The connection with the connection part 67 is maintained. In this state, the bristle brush portion 34 is positioned around the connection portion 67 and fits into the recess 66, and the mounting portion 33, the rotary tube portion 32, and the main body portion 31 of the rotary tube unit 25 are respectively located behind the recess 66 (external ). The spheres 75 and 75 are located behind the notch opening 64 of the floor brush 26, and the lower portions of the spheres 75 and 75 are substantially equal to the lower surface 62 (the raised cloth portion 65) of the case body 61 of the floor brush 26. The suction port 63 and the cutout opening 64 are connected to the rotary tube unit 25 in an airtight manner through the opening 72, the connecting portion 67, and the fitting portion. As a result, the lower portions of the spheres 75 can be brought into contact with the floor surface.

  Further, when cleaning using the bristle brush part 34, when the operator contracts the arm that grips the grip part 28 (when pulling the arm), that is, the bristle brush part 34 is positioned relatively close to the worker. 6 (a), the tube portion 13 stands in a state of being nearly perpendicular to the surface to be cleaned S, so that the bristle brush 52 of the bristle brush portion 34 is respectively on the surface to be cleaned S. It becomes a state of standing substantially vertically. For this reason, the spheres 75 of the rotary tube unit 25 are separated from the surface S to be cleaned.

  Further, when the operator extends the arm holding the grip portion 28 (when pressing with the arm), that is, when the bristle brush portion 34 is positioned at a position relatively far from the worker, it is shown in FIG. As described above, the tube portion 13 lies down (collapses) in a state where the tube portion 13 is inclined by a predetermined angle or more with respect to the surface to be cleaned S. The side surface is in contact with the surface to be cleaned S. For this reason, the spheres 75, 75 of the rotary tube unit 25 are relatively close to the surface to be cleaned S, and assist the traveling of the bristle brush portion 34 on the surface to be cleaned S.

  Thus, when cleaning using the bristle brush part 34, at least the rotary tube unit 25 is removed from the floor brush 26 and a part of the bristle brush part 34 is in contact with the surface S to be cleaned, By having the same configuration as in the first embodiment, such as 75 contacting the surface to be cleaned S, the same operational effects as in the first embodiment can be obtained.

  Further, by using the spherical body 75 as the rotating body, the bristle brush portion 34 or the floor brush 26 can be easily traveled not only in the front-rear direction but also in the left-right direction, and the operability is further improved.

  Furthermore, by forming the spheres 75 and 75 with a soft member, it is possible to reduce the impact sound when the spheres 75 and 75 are in contact with the surface to be cleaned S and to prevent the surfaces 75 and 75 from being damaged. it can.

  In each of the above embodiments, the rotary tube unit 25 is separated from the extension tube 24. However, for example, the extension tube 24 and the rotary tube unit 25 may be integrated.

  Similarly, in the rotary tube unit 25, the bristle brush part 34 is separated from the main body part 31, but the bristle brush 52 may be directly planted at the distal end of the main body part 31.

  Further, the vacuum cleaner 11 is not limited to a canister type, and for example, an upright type in which the floor brush 26 is connected to the lower part of a vertically long vacuum cleaner main body or a handy type may be used correspondingly.
