  • suction tool unit 20 includes suction tool 30 and coupling pipe 40.
  • Suction tool 30 includes case 31, shutter 32, rotating brush 33, and rollers 34. It is to be noted that as shown in FIG. 2 , a dimension of suction tool 30 along longitudinal direction ZD is greater than the dimension of, for example, suction unit 70 along widthwise ZB, that is to say, the maximum width of main body 10.
  • case 31 includes suction hole 31Q that opens at bottom face 31P.
  • Rotating brush 33 is disposed in suction hole 31Q.
  • Shutter 32 is provided at a front part of case 31 to be movable relative to case 31. As such, shutter 32 opens or closes the front part of case 31. As the front part of case 31 is opened, suction hole 31Q opens even at the front part of case 31 (refer to FIG. 10 ).
  • Rollers 34 are provided at a front face of shutter 32 and rotate along longitudinal direction ZD of suction tool 30. Rollers 34 enables smooth movement of suction tool 30 in cases where suction tool 30 is moved along widthwise ZB while making contact with a wall or a floor.
  • Rotating brush 33 includes base 33a, a plurality of first bristle brushes 33b and a plurality of second bristle brushes 33c.
  • Base 33a is supported by case 31 to be rotatable relative to case 31.
  • a plurality of first bristle brushes 33b and second bristle brushes 33c are implanted in a peripherally alternating manner in an outer periphery of base 33a.
  • First bristle brushes 33b are each implanted in base 33a without gaps along a longitudinal direction of base 33a (that corresponds to longitudinal direction ZD of suction tool 30).
  • Each of the plurality of second bristle brushes 33c includes a plurality of unit brushes 33d that are implanted at regular intervals along the longitudinal direction of base 33a.
  • Gap 33e is thus formed between adjacent unit brushes 33d to allow air to flow smoothly.
  • shutter 32 being open, air in front of case 31 flows into case 31 through gaps 33e.
  • a resistance to the air that flows into is small as compared with cases where gaps 33e are not formed. Accordingly, suction tool unit 20 has increased suction power. Consequently, dust can be collected efficiently with lower power consumption.
  • Coupling pipe 40 is connected to extension pipe 60 shown in FIG. 2 .
  • suction tool 30 is connected so as to be rotatable relative to coupling pipe 40 about first axis JX1, which is a central axis of rotation of coupling pipe 40.
  • cleaner 1 can assume a plurality of configurations according to how suction tool 30 is rotated.
  • the plurality of configurations includes, for example, a first configuration, a second configuration, and a third configuration that are described below with reference to FIGS. 6 to 8 and FIGS. 13 and 19 .
  • the first configuration has a first state that is assumed by suction tool 30, and is used when floor FL is cleaned. As shown in FIG. 2 , the first state is such that longitudinal direction ZD of suction tool 30 is parallel to widthwise ZB of cleaner 1.
  • the second configuration has a second state that is assumed by suction tool 30 in the course of cleaner 1 switching from the first configuration to the third configuration.
  • the second state is such that when cleaner 1 is viewed from its side as shown in FIG. 13 , longitudinal direction ZD of suction tool 30 is orthogonal to lengthwise ZA of cleaner 1.
  • the second configuration is assumed in cases where floor FL of a narrow space such as between pieces of furniture is cleaned.
  • the third configuration has a third state that is assumed by suction tool 30, and is used when cleaner 1 is disposed in a specified storage space, such as on a stand.
  • the third state is such that when cleaner 1 is viewed from its front as shown in FIG. 19 , suction tool 30 is disposed with its longitudinal direction ZD being along lengthwise ZA of main body 10.
  • suction tool 30 further includes nozzle motor 35 and rotation control part 36, for example.
  • Nozzle motor 35 and rotation control part 36 are accommodated by case 31.
  • Nozzle motor 35 is driven by electric power supplied from battery unit 100 (refer to FIG. 1 ) and thus causes rotating brush 33 to rotate.
  • Case 31 includes communicating pipe 31a and support 31b.
  • Communicating pipe 31a is provided inside case 31 to communicate with suction hole 31Q that opens at bottom face 31P.
  • Support 31b supports a portion of coupling pipe 40 that is inserted in case 31 such that coupling pipe 40 is rotatable relative to suction tool 30.
  • Coupling pipe 40 is formed of, for example, first coupling pipe 41, second coupling pipe 42, and restriction part 43.
  • First coupling pipe 41 is disposed inside case 31 and is connected to communicating pipe 31a.
  • First coupling pipe 41 includes flange 41a along its outer periphery. Flange 41a is accommodated by support 31b.
  • Second coupling pipe 42 is connected to extension pipe 60 (refer to FIG. 1 ) to be nonrotatable relative to extension pipe 60.
  • Connection part 40X between first coupling pipe 41 and second coupling pipe 42 is formed of a ball joint.
  • Connection part 40X includes, as a central axis of rotation, second axis JX2 that parallels at least widthwise ZB of cleaner 1.
  • Restriction part 43 is mounted to case 31 so as to partly cover connection part 40X. Restriction part 43 restricts such first coupling pipe 41 and second coupling pipe 42 so as not to rotate about the axis other than second axis JX2. Thus, first coupling pipe 41 and second coupling pipe 42 relatively rotate only about second axis JX2.
  • Suction tool unit 20 further includes rotational structure S.
  • Rotational structure S allows suction tool 30 to rotate relative to main body 10 such that longitudinal direction ZD of suction tool 30 runs along lengthwise ZA (refer to FIG. 2 ) of main body 10.
  • Rotational structure S includes first rotational structure S1 and second rotational structure S2.
  • First rotational structure S1 allows suction tool 30 to rotate relative to coupling pipe 40 about first axis JX1.
  • Second rotational structure S2 allows suction tool 30 to rotate relative to coupling pipe 40 about second axis JX2. It is to be noted that second rotational structure S2 is formed of connection part 40X between first coupling pipe 41 and second coupling pipe 42, and restriction part 43.
  • first axis JX1 is disposed parallel to orthogonal direction ZE that is orthogonal to longitudinal direction ZD. Specifically, first axis JX1 is disposed, for example, in a middle of longitudinal direction ZD of suction tool 30 as well as in a middle of heightwise (thickness-wise) ZF of suction tool 30.
  • second axis JX2 is disposed parallel to widthwise ZB when main body 10 is viewed from its front as shown in FIG. 2 .
  • Second axis JX2 is disposed, for example, in the middle of heightwise ZF of suction tool 30.
  • Coupling pipe 40 further includes lock mechanism 50.
  • Lock mechanism 50 locks relative rotation between first coupling pipe 41 and second coupling pipe 42.
  • lock mechanism 50 can assume an unlocking state that enables first coupling pipe 41 and second coupling pipe 42 to relatively rotate, and a locking state that disenables first coupling pipe 41 and second coupling pipe 42 to relatively rotate.
  • Lock mechanism 50 includes projection 51 that is formed on second coupling pipe 42, and protrusion 52 that is formed on restriction part 43. The locking state and the unlocking state depend on whether or not projection 51 and protrusion 52 engage with each other.
  • Suction tool unit 20 of the present exemplary embodiment has the structure such as above.
  • first rotational structure S1 of rotational structure S in suction tool unit 20 With reference to FIGS. 6 to 8 , structure and operation of first rotational structure S1 of rotational structure S in suction tool unit 20 are described below.
  • First rotational structure S1 is formed of rotation control part 36 including piston 36a and elastic members 36b.
  • Rotation control part 36 controls rotation of suction tool 30 relative to coupling pipe 40 about first axis JX1.
  • Piston 36a is disposed inside case 31 to make contact with flange 41a of first coupling pipe 41 while being movable along longitudinal direction ZD of case 31.
  • Elastic members 36b are disposed inside case 31 so as to apply urging force that presses piston 36a against flange 41a.
  • elastic member 36b illustrated is, for example, a coil spring.
  • Flange 41a is formed to be, for example, quadrangular.
  • Flange 41a has, at respective two adjacent corners of its side positioned opposite to piston 36a that makes contact with flange 41a, projections 41b that project toward support 31b.
  • Support 31b includes wall part 31c that is, for example, arc-shaped on its side positioned opposite to piston 36a across first axis JX1 along longitudinal direction ZD of suction tool 30.
  • First rotational structure S1 of rotational structure S has the structure such as above.
  • top face 36aa of piston 36a of rotation control part 36 is entirely pressed against first side face 41d of flange 41a.
  • one of projections 41b that is formed at the corner of flange 41a is pressed against wall part 31c of support 31b.
  • frictional force takes place between flange 41a and piston 36a as well as between flange 41a and wall part 31c.
  • the frictional force acts to resist force that effects relative rotation between suction tool 30 and first coupling pipe 41.
  • suction tool 30 is easy to maintain the first state.
  • suction tool 30 and coupling pipe 40 are relatively rotated accordingly. This results in a change of position of contact between flange 41a and piston 36a.
  • a rotation angle of suction tool 30 is less than a predetermined angle
  • urging force of elastic members 36b of rotation control part 36 acts to restore a rotational position of suction tool 30 to a rotational position of the first state.
  • suction tool 30 is normally restored to the first state.
  • the rotation angle is an angle through which suction tool 30 is rotated from its first state.
  • the predetermined angle is 45°.
  • top face 36aa of piston 36a makes contact with apex 41e of flange 41a.
  • piston 36a is maximally pushed against elastic members 36b.
  • suction tool 30 and coupling pipe 40 relatively rotate.
  • Top face 36aa of piston 36a thus comes into contact with second side face 41f of flange 41a.
  • the urging force of elastic members 36b of rotation control part 36 acts to bring suction tool 30 closer to a rotational position of the second state. As such, even without application of turning force to suction tool 30 and coupling pipe 40, suction tool 30 is rotated to the second state. Consequently, enhanced ease of use is obtained.
