FIG. 4A is a left side view of the suction unit 5, and FIG. 4B is a right side view of the suction unit 5. FIG. 5 is a cross-sectional view of the suction section cut along line BB shown in FIG.

(Gripping part)
As shown in FIGS. 3 and 4, the suction portion 5 has a rectangular parallelepiped shape with a long side portion curved. That is, the suction part 5 has a shape in which the long side portion of the rectangular parallelepiped is rounded off. The suction part 5 has a front surface, a back surface, a left side surface, and a right side surface formed in a curved shape. The suction portion 5 gradually swells from the end side where the pipe connection portion 38 is provided, and has a maximum width at the substantially central portion where the first exhaust port group 19 and the second exhaust port group 20 are formed. It has a shape that gradually narrows toward the provided end.

  The suction part 5 includes a housing 51 in which a suction port 38a for sucking outside air is formed. The casing 51 includes a first casing member 51a and a second casing member 51b. The first housing member 51a and the second housing member 51b are fixed to each other by a plurality of screws N1 (see FIG. 4A).

  The grip portion 21 is provided on the housing 51. The gripping part 21 is formed in a thickness that can be sufficiently gripped by a person who uses the cleaner 1 regardless of age or sex. Moreover, the finger passage part 25 provided between the holding part 21 and the back surface side of the housing | casing 51 is formed in the magnitude | size which the user of the cleaner 1 can pass a finger smoothly. The suction part 5 is configured such that the user can grasp the grip part 21 with a finger other than the thumb passed through the finger passage part 25. In the vicinity of the operation portion 23 of the finger passage portion 25, a finger guide portion 21a that protrudes toward the operation portion 23 side is provided (see FIGS. 4A and 4B). The finger guide portion 21a is provided to guide the location of the index finger when the user of the cleaner 1 holds the grip portion 21.

(Operation section)
The operation unit 23 provided in the suction unit 5 includes a first operation button 23a, a second operation button 23b, and a third operation button 23c. The first operation button 23a is a button for operating the suction unit 5 with a fixed suction force. The second operation button 23b is a button for operating the suction unit 5 by detecting the amount of dust scattered on the floor and automatically changing the suction force. The third operation button 23 c is a button for stopping the operation of the suction unit 5. When the user of the vacuum cleaner 1 places an index finger on the finger guide portion 21a to grip the grip portion 21 and places a thumb on the front side of the suction portion 5, the operation portion 23 is disposed at the position of the thumb. The third operation button 23 c is provided on the grip portion 21, and the first operation button 23 a and the second operation button 23 b are disposed at positions shifted from the grip portion 21. The first operation button 23a and the second operation button 23b that are frequently used when the cleaner body 3 is used are arranged on the fingertip side of the user's thumb, and the third operation button 23c that is less frequently used when the cleaner body 3 is used. Is placed on the base side of the thumb. Thereby, as for the vacuum cleaner 1, the operativity of the operation part 23 is improved.

(Pipe connection)
The suction part 5 has a pipe connection part 38 to which the extension pipe 4 is connected. The pipe connecting portion 38 has a cylindrical shape with an inclined end portion on the side to which the extension pipe 4 is connected (see FIGS. 4A and 4B). The pipe connection portion 38 is formed so as to be inclined so that the front side of the end portion is longer than the back side. A suction port 38 a is provided at this end of the pipe connection portion 38. The suction port 38 a serves as an opening for sucking air from the outside into the internal space of the pipe connection part 38. The internal space of the pipe connection portion 38 communicates with the dust collection portion 900 (see FIG. 5) of the suction portion 5. For this reason, the air sucked into the pipe connection part 38 from the suction port 38 a is sucked into the dust collecting part 900 of the suction part 5.

  A removal lever 11 is provided on the front side of the pipe connection portion 38. The removal lever 11 has a thin plate rectangular shape. As shown in FIG. 5, the removal lever 11 includes a spring member 11b. The removal lever 11 is biased by a spring member 11b. The removal lever 11 is maintained in a state along the extending direction of the pipe connecting portion 38 by the biasing force of the spring member 11b unless an external force is applied.

  A protrusion 11 c that protrudes into the internal space of the pipe connection portion 38 is formed on the rear surface of the removal lever 11 (the surface on the internal space side of the pipe connection portion 38). On the other hand, on the surface of the end portion of the extension pipe 4 to be inserted into the pipe connection portion 38, a lever receiving portion (not shown) that is depressed so that the protruding portion is caught is formed. When this end portion of the extension pipe 4 is inserted into the internal space of the pipe connection portion 38 from the suction port 38a, the protruding portion of the removal lever 11 contacts the surface of the extension pipe 4. The urging force of the spring member 11 b cannot resist the force that the surface of the extension pipe 4 pushes the protruding portion 11 c of the removal lever 11 toward the outer surface of the pipe connecting portion 38. Thereby, when the end portion of the extension pipe 4 is inserted into the internal space of the pipe connection portion 38, the end portion side of the removal lever 11 opposite to the suction port 38a side is pushed up. When the end portion of the extension pipe 4 is continuously inserted into the internal space of the pipe connection portion 38, the lever receiving portion formed on the surface of the extension pipe 4 reaches a position facing the protruding portion 11 c of the removal lever 11. If it does so, since the removal lever 11 will not receive external force from the extension pipe 4, it will return to the state along the extending direction of the pipe connection part 38 with the urging | biasing force of the spring member 11b. Thereby, the protrusion part of the removal lever 11 is hooked on the lever receiving part of the extension pipe 4. As a result, even if the extension pipe 4 is pulled in a direction away from the suction portion 5, it does not come off the suction portion 5.

  A finger guide portion 11a that is slightly depressed in a circular shape is formed at the end portion of the removal lever 11 opposite to the end portion where the protruding portion 11b is formed. The urging force of the spring member 11b that urges the removal lever 11 is not so strong as to resist the force of the user of the cleaner 1. For this reason, the removal lever 11 is lifted in a direction in which the end portion provided with the protruding portion 11c is separated from the pipe connection portion 38 by the amount that the user of the cleaner 1 pushes the finger guide portion 11a toward the pipe connection portion 38 side. When the extension pipe 4 is attached to the pipe connection portion 38 and the user of the cleaner 1 pushes down the finger guide portion 11 a toward the pipe connection portion 38, the protrusion 11 c of the removal lever 11 receives the lever receiver of the extension pipe 4. The state of being caught on the part is released. Accordingly, when the user of the cleaner 1 pulls the extension pipe 4 away from the suction part 5 while pushing down the finger guide part 11a, the extension pipe 4 is detached from the pipe connection part 38.

  The end portion of the joint portion 16 provided in the suction head portion 2 is formed in the same shape as the end portion of the extension pipe 4 on the side inserted into the suction portion 5. For this reason, the suction head part 2 can be attached to and detached from the suction part 5 by the same principle as the extension pipe 4. Thereby, the suction part 5 can be used as a handy type cleaner with the suction head part 2 attached thereto.

  The end portion of the extension pipe 4 on the side where the removal lever 12 is provided has the same structure as the end portion of the pipe connection portion 38 except that the end portion is not formed to be inclined. The removal lever 12 has the same structure as the removal lever 11 although the length is different. For this reason, the suction head part 2 can be attached to and detached from the extension pipe 4 by the same principle as the pipe connection part 38.

  Returning to FIGS. 3 and 4, the pipe connection portion 38 is provided with the brush portion 15. The brush part 15 has a rotating part 15a having a rotating shaft (not shown) for rotating with respect to the pipe connecting part 38, and a tip part 15b provided at the tip of the rotating part 15a. When the suction head unit 2 is connected to the suction unit 5 directly or via the extension pipe 4, the brush unit 15 is disposed so as to surround the left side, the back side, and the right side of the pipe connection unit 38. (See FIG. 3B, FIG. 4A, and FIG. 4B). On the other hand, when the suction part 5 is used as a brush-type handy vacuum cleaner without connecting the suction head part 2 and the extension pipe 4, the brush part 15 has a left side surface, a front side and a right side of the pipe connection part 38. It is arranged on the surface side so as to surround the suction port 38a. When the brush portion 15 is disposed so as to surround the suction port 38a, the surface including the tip of the tip portion 15b is disposed substantially parallel to the end surface of the pipe connection portion 38 in which the suction port 38a is formed. For this reason, by bringing the tip of the tip portion 15b into contact with the surface to be cleaned, the suction port 38a is disposed substantially facing the surface to be cleaned. Thereby, the suction part 5 can suck efficiently the dust scattered on the surface to be cleaned while scooping it out with the tip part 15b.

(Dust collector cover)
As shown in FIG. 3A and FIG. 4, the dust collecting unit cover 17 provided in the suction unit 5 is provided on a part of the front side, a part of the left side, and a part of the right side of the suction part 5.

The rotation mechanism 510 holds the dust collecting unit cover 17 so as to be rotatable with respect to the housing 51. The dust collecting unit cover 17 is held in a state substantially orthogonal to the housing 51 by the biasing force of the spring member of the rotation mechanism 510 when no external force is applied. When the dust collecting unit cover 17 is held in a state substantially orthogonal to the casing 51, the casing 51 is opened and the dust collecting section 900 provided in the internal space of the casing 51 is exposed to the outside.

  On the other hand, the casing 51 is provided with a protruding portion 130 that protrudes toward the dust collecting portion 900 side in the vicinity of the short side of the dust collecting portion cover 17 on the pipe connecting portion 38 side. The protruding portion 130 is disposed between the vicinity of the short side of the dust collecting portion cover 17 and the cover button 13. The projecting portion 130 is maintained in a state of projecting to the dust collecting unit 900 side in a normal state where the cover button 13 is not pushed down. The jump-out part 130 is configured to retreat to the pipe connection part 38 side in conjunction with the cover button 13 being pushed down. A spring member 13 a is provided below the cover button 13. The cover button 13 is normally maintained in a state where it is not pushed down by the urging force of the spring member 13a. For this reason, the flying part 130 is maintained in a state where the cover button 13 is not applied with an external force and is projected to the dust collecting part 900 side except when the dust collecting part 900 is closed with the dust collecting part cover 17. .

  Here, a schematic configuration of the dust collecting unit cover 17 will be described with reference to FIG. FIG. 6 is an orthographic view of the dust collecting unit cover 17.

On the short side of the dust collecting unit cover 17 disposed on the gripping unit 21 side when the dust collecting unit cover 17 is attached to the housing 51, a pair of bent portions outward from the packing arranging unit 174 is formed in a predetermined shape. The bearing portion 173 is provided. The pair of bearing portions 173 is attached to a rotation shaft of a rotation mechanism 510 (see FIG. 5) provided in the housing 51. Thereby, the dust collecting unit cover 17 is rotatably held by the rotation mechanism 510.

  The dust collection unit cover 17 includes a hollow protrusion 172 provided on a part of the other short side of the dust collection unit cover 17 and surrounded by the packing arrangement unit 174. The hollow protrusion 172 is formed so as to protrude from the surface of the lid 171 on which the packing arrangement portion 174 is formed. When the dust collection unit 900 is closed by the dust collection unit cover 17, the hollow protrusion 172 holds the dust collection unit 9 (see FIG. 5, details will be described later) disposed on the dust collection unit 900 against the dust collection unit 900. It is supposed to be attached.

  On the short side of the dust collecting portion cover 17 on the side where the hollow protrusion 172 is provided, a pop-out receiving portion 175 that protrudes outward from the packing arrangement portion 174 is provided. The pop-out receiving part 175 is formed in a wedge shape. The pop-out receiving portion 175 has a rectangular flat surface facing the lid portion 171 and an inclined surface inclined from the flat portion toward the end of the packing arrangement portion 174 on the side where the packing is attached. . The pop-out receiving portion 175 is provided at a location corresponding to a position where the pop-out portion 130 pops out when the dust collecting portion 900 is closed by the dust collecting portion cover 17. When the dust collection unit cover 17 is tilted toward the housing 51 so as to block the exposed dust collection unit 900, the flying unit 130 is pressed against the inclined surface of the flying receiving unit 175. The spring member 13 a of the cover button 13 cannot resist the force received by the projecting portion 130 from the projecting receiving portion 175. For this reason, the jumping-out part 130 once moves backward to the pipe connecting part 38 side. However, when the dust collecting unit cover 17 is in contact with the housing 51 in a state where the dust collecting unit 900 is closed, the projecting unit 130 is positioned in a space between the flat surface of the projecting receiving unit 175 and the lid unit 171. And no external force. For this reason, the cover button 13 is pushed up in order for the spring member 13a to return to the original state. The jumping portion 130 returns to the state where it jumps out by pushing up the cover button 13, and maintains a state where it protrudes between the jumping receiving portion 175 and the lid portion 171. The dust collecting unit cover 17 is about to rise by the rotation mechanism 510, but the flying unit 130 is caught on the flat surface of the flying receiving unit 175. The biasing force of the spring member of the rotation mechanism 510 is not so strong as to release the state in which the projecting portion 130 is caught by the projecting receiving portion 175. For this reason, when the projecting portion 130 is caught by the projecting receiving portion 175, the dust collecting unit cover 17 is held by the housing 51 in a state where the dust collecting unit 900 is closed. If the cover button 13 is pushed down when the dust collecting unit cover 17 is held by the casing 51 with the dust collecting unit 900 closed, the flying unit 1130 moves backward to the pipe connecting unit 38 side. The state where the protruding portion 130 is caught by the pop-out receiving portion 175 is released. As a result, the dust collecting unit cover 17 is rotated about a part of the rotation mechanism 510 by the urging force of the rotation mechanism 510 as a rotation axis, and is almost orthogonal to the housing 51. Thereby, the dust collection part 900 is exposed outside.

  The packing arrangement portion 174 is formed to be slightly larger than the opening that allows the internal space of the dust collection portion 900 to communicate with the outside. For this reason, when the dust collection part cover 17 closes the dust collection part 900, the packing arrange | positioned at the packing arrangement | positioning part 174 closely_contact | adheres with a part of the housing | casing 51 arrange | positioned around the opening of the dust collection part 900. Thereby, the sealing degree of the internal space of the dust collection part 900 improves, and the suction power of the suction part 5 improves. When the suction force of the suction unit 5 is improved, the number of rotations of a motor 61 (details will be described later) that rotates a suction fan 62 (details will be described later) can be reduced, so that power consumption can be reduced. Thereby, since the operation | movement period of the suction part 5 becomes long, the operativity of the cleaner 1 can be aimed at.

(Dust collector)
Returning to FIG. 5, the space forming the dust collection portion 900 is communicated with the internal space 38 b of the pipe connection portion 38. For this reason, the air sucked from the suction port 38a can reach the dust collecting portion 900. In addition, the dust collection unit 9 is detachably disposed at the boundary between the space forming the dust collection unit 900 and the internal space 38b of the pipe connection unit 38. A packing 380 is attached to an end portion of the pipe connection portion 38 that is a boundary portion with the dust collection portion 900. The dust collection unit 9 is disposed in the dust collection unit 900 in a state of being in close contact with the packing 380. Thereby, the improvement of the adhesion degree of the pipe connection part 38 and the dust collection part 9 is achieved. The dust collecting unit 9 is provided with an opening at a position corresponding to the internal space 38 b of the pipe connecting unit 38 when the dust collecting unit 9 is attached to the dust collecting unit 900. For this reason, the air and dust sucked from the suction port 38 a flow into the dust collecting unit 9. The dust collection unit 9 is disposed in the dust collection unit 900 in a state where a dust collection bag (not shown) is attached. The dust bag is configured not to allow dust to pass while allowing air to pass. Therefore, the air that has flowed into the dust collection unit 9 flows into the dust collection unit 900 through the dust collection bag. On the other hand, the dust that has flowed into the dust collecting unit 9 is collected in the dust collecting bag and does not flow into the dust collecting unit 900.

  Here, a schematic configuration of the dust collecting unit 9 will be described with reference to FIGS. 7 and 8 with reference to FIG. FIG. 7 is a perspective view of the dust collecting unit 9 as viewed from the side from which the blown air flows out. FIG. 8 is an orthographic view of the dust collecting unit 9. A top view of FIG. 8 shows a plan view of the dust collecting unit 9. A left side view of the dust collecting unit 9 from the left is shown in the middle stage of FIG. A front view, a right side view, and a rear view are shown in this order, and a bottom view of the dust collecting unit 9 is shown in the lower part of FIG.

  As shown in FIGS. 7 and 8, the dust collecting portion 9 includes a plate-like portion 91 formed in a rectangular shape with a through-hole 911 c in the center, and an inner wall of the through-hole 911 c formed in the plate-like portion 91. And a cylindrical portion 92 that is formed so as to protrude from the plate-like portion 91. A through hole 911 c formed in the plate-like portion 91 is an opening provided at a position corresponding to the internal space 38 b of the pipe connection portion 38. Further, the cylindrical portion 92 having an inner wall formed integrally with the through hole 911c serves as a flow path for circulating the air that has passed through the internal space 38b of the pipe connection portion 38 to the dust collection portion 900. In addition, the dust bag is attached so as to cover the cylindrical portion 92 from the end portion side on the air outflow side. The dust bag is formed in a bag shape using, for example, a nonwoven fabric. As a result, the air that has flowed into the dust bag through the cylindrical portion 92 can flow to the outside of the dust bag, but the dust that has flowed into the dust bag through the cylindrical portion 92 is collected. It cannot flow outside the dust bag and is collected inside the dust bag.

  The dust collection unit 9 includes a bag holding unit 93 that holds a dust collection bag. The bag holding portion 93 includes stretch holding members 931 a and 931 b that are fixed to the plate-like portion 91 and extend toward the outer surface of the cylindrical portion 92. The stretch holding member 931a and the stretch holding member 931b are arranged with a predetermined gap. The stretch holding members 931a and 931b are formed so as to be away from the cylindrical portion 92 from the contact portion with the outer surface of the cylindrical portion 92 to the tip. That is, the extension holding members 931 a and 931 b include end portions that are bent away from the cylindrical portion 92.

  The dust collection unit 9 includes a bag holding unit 94 that is disposed to face the bag holding unit 93 with the tube unit 92 interposed therebetween and holds the dust collection bag. The bag holding portion 94 has stretch holding members 941a and 941b that are fixed to the plate-like portion 91 and extended toward the outer surface of the cylindrical portion 92. The stretch holding member 941a and the stretch holding member 941b are arranged with a predetermined gap. The stretch holding members 941a and 941b are formed so as to be away from the cylindrical portion 92 from the contact portion with the outer surface of the cylindrical portion 92 to the tip. That is, the extension holding members 941 a and 941 b include end portions that are bent away from the cylindrical portion 92.

  The stretch holding members 931a, 931b, 941a, 941b have an elastic force. For this reason, when the dust bag is sandwiched between the extension holding members 931a, 931b, 941a, 941b and the cylindrical portion 92 and attached to the dust collecting portion 9, the elasticity of the extension holding members 931a, 931b, 941a, 941b. It is pressed against the outer surface of the cylindrical portion 92 by force. Accordingly, the bag holding portions 93 and 94 can prevent the dust collection bag from being detached from the dust collection portion 9 due to the air pressure of the air flowing through the cylinder portion 92. In addition, even if the dust collecting unit 9 to which the dust collecting bag is attached is placed on or removed from the dust collecting unit 900, the bag holding units 93 and 94 are separated from the dust collecting unit 9. Can be prevented.

  In addition, since the end portions of the stretch holding members 931a, 931b, 941a, 941b are bent, the bag holding portions 93, 94 collect dust between the stretch holding members 931a, 931b, 941a, 941b and the cylindrical portion 92. Easy to insert the bag.

  The plate-like portion 91 has a wedge shape whose thickness decreases from one of a pair of opposing sides to the other. As shown in the left side view and the right side view in FIG. 8, the cylindrical portion 92 is formed substantially orthogonal to the plate-like portion 91. The surface of the plate-like portion 91 on the side where the cylindrical portion 92 is not formed is inclined with respect to the extending direction of the cylindrical portion 92. The plate-like portion 91 has curved cutout portions 911a and 911b at both ends of the thicker side end portion. Since the dust collecting part 9 is inserted into the dust collecting part 900 from the thin end side of the plate-like part 91, the notches 911a and 911b are used when the dust collecting part 9 is attached to and detached from the dust collecting part 900. In addition, it is used as a picking part that the user of the vacuum cleaner 1 picks with a finger.

  Returning to FIG. 5, when the dust collection unit 900 is closed by the dust collection unit cover 17 after the dust collection unit 9 is installed in the dust collection unit 900, the hollow protrusion 172 formed on the dust collection unit cover 17 is plate-shaped. The portion 91 is in contact with the thickest side end. For this reason, the dust collector cover 17 can fix the dust collector 9 by pressing it against the dust collector 900. Thereby, since the dust collection part 9 can be prevented from moving in the dust collection part 900 at the time of operation | movement of the suction part 5, the sealing degree of the dust collection part 900 is improved.

  A thin plate member 153 is disposed on the opening end side of the dust collection unit 900 and in the vicinity of the packing 380. The thin plate member 153 is biased by being inclined toward the opening end side of the dust collection unit 900 by a spring member (not shown) attached to the housing 51 when the dust collection unit 9 is not disposed in the dust collection unit 900. The For this reason, even if the dust collecting part cover 17 tries to block the dust collecting part 900 in a state where the dust collecting part 9 is not arranged in the dust collecting part 900, the hollow protrusion 172 collides with the thin plate member 153, and the dust collecting part 900 does not collect. The dust cover 17 cannot be closed. Accordingly, the suction unit 5 cannot be used in a state where the dust collection unit 9 is not disposed in the dust collection unit 900. Thus, the thin plate member 153 can prevent the malfunction of the suction portion 5, that is, the cleaner body 3.

  When the dust collecting unit 9 is disposed in the dust collecting unit 900, the thin plate member 153 is pushed down to the side where the pipe connection unit 38 is provided by the inclined surface of the plate-like unit 91 as shown in FIG. Thus, when the dust collection unit 900 is closed by the dust collection unit cover 17, the hollow protrusion 172 can contact the plate-like portion 91 without colliding with the thin plate member 153.

(Blower means)
Next, the air blowing means provided in the internal space of the housing of the suction unit 5 will be described with reference to FIG. 5 and FIG. FIG. 10 is a perspective view of the air guide portion 63 that improves the suction force of the suction fan 62.

  As shown in FIG. 5, the suction unit 5 improves the suction force of the suction fan 62 that sucks air into the cleaner body 3 to generate an air flow, the motor 61 that drives the suction fan 62, and the suction fan 62. And an air guide portion 63 to be operated. The motor 61, the suction fan 62, and the air guide 63 constitute a blowing means. The motor 61, the suction fan 62, and the air guide unit 63 are disposed in the internal space of the housing 51. The motor 61 is arranged in a motor arrangement area 650 that is a part of the internal space of the housing 51. The suction fan 62 is arranged in a fan arrangement area 600 that is another part of the internal space of the casing 51.

  In the motor arrangement area 650, a motor arrangement section 601 for arranging the motor 61 is provided. The motor placement unit 601 is formed integrally with the housing 51. The motor 61 is arranged in the motor arrangement unit 601 in a bare state, not in a state accommodated in a motor case or the like. The motor arrangement unit 601 is provided with a first arrangement member 601a provided on the power supply terminal side for supplying electric power to the motor 61, and a second arrangement provided on the side from which the rotary shaft member to which the suction fan 62 is attached projects. Member 601b. The motor 61 is fixed to the housing 51 between the first placement member 601a and the second placement member 601b. The first arrangement member 601a supports a part of the motor 61 on the power supply terminal side, and the second arrangement member 601b supports a part of the motor 61 on the side where the rotating shaft member protrudes. The motor 61 is partially supported by the first placement member 601 a and the second placement member 601 b in the motor placement region 650, and the remaining portion is exposed in the internal space of the housing 51.

  The fan arrangement area 600 is an area partitioned from the other internal space of the housing 51 by the first partition plate 501 and the second partition plate 502. The first partition plate 501 and the second partition plate 502 are formed integrally with the housing 51. The first partition plate 501 partitions the fan arrangement area 600 and the motor arrangement area 650. The second arrangement member 601b is formed integrally with the first partition plate 501. The first partition 501 is provided with an opening for inserting the rotating shaft member of the motor 61 into the fan arrangement region 600. Thus, the suction fan 62 is fixed to the rotating shaft member of the motor 61 and can be rotated along with the rotation of the rotating shaft member of the motor 61. The second partition plate 502 partitions the fan arrangement area 600 and the dust collection unit 900. The second partition plate 502 is provided with an opening for guiding the air introduced from the dust collecting unit 9 to the dust collecting unit 900 to the fan arrangement region 600. A part of the air guide portion 63 is exposed in this opening.

  The suction fan 62 is a centrifugal fan that rotates as the motor 61 rotates and blows out air sucked from the center toward the outer periphery. The suction fan 62 includes a thin plate-shaped first disk member 621 and a second disk member 622 whose central portion is inclined in a curved shape on the side opposite to the side where the first disk member 621 is disposed. The first disk member 621 and the second disk member 622 are arranged to face each other with a predetermined gap. In the center of the first disk member 621, a core member 624 connected to the rotating shaft member of the motor 61 is provided.

  The suction fan 62 has a plurality of wing members 623 disposed between the first disk member 621 and the second disk member 622. The plurality of wing members 623 are formed in a curved radial shape from the center side of the first disk member 621 and the second disk member 622 toward the outer peripheral side. An opening 62 a is formed at the center of the second disk member 622. The suction fan 62 sucks air from the opening 62a, and blows the sucked air toward the outer circumference of the first disk member 621 and the second disk member 622 through the space between the adjacent wing members 423. Yes.

  As shown in FIG. 9, the air guide part 63 has a thin-plate circular shape as a whole. The air guide portion 63 is disposed on the second disk member 621 side of the suction fan 62. The air guide part 63 has a placement part 631 on which the suction fan 62 is placed. The placement portion 631 is formed in a shape that follows the outer surface of the second disk member 621. For this reason, the suction fan 62 can smoothly rotate while being placed on the air guide portion 63. An opening 63 a is formed at the center of the mounting portion 631. The suction fan 62 sucks air through the opening 63 a formed in the mounting portion 631 and the opening 62 a formed in the second disk member 622. The air guide portion 63 includes a plurality of first rod-like members 633 formed on the back surface side (side on which the dust collecting portion 900 is provided) of the placement portion 631 and a plurality of second rod-like shapes formed on the opening 63a. Member 632. When the air guide portion 63 is viewed from the dust collection portion 900 side, it appears that the first rod-shaped member 633 is disposed around the second rod-shaped member 632. A gap slightly longer than the thickness of the second partition plate 502 is provided between the first rod-shaped member 633 and the second rod-shaped member 632.

  Returning to FIG. 5, the air guide portion 63 is installed in the housing 51 in a state where the second partition plate 502 is sandwiched between the first rod-shaped member 633 and the second rod-shaped member 632. Thereby, most of the air discharged from the dust collecting unit 9 to the dust collecting unit 900 is sucked into the suction fan 62 through the opening 63a and the opening 62a. For example, almost no air is sucked into the suction fan 62 through a route that once flows into the fan arrangement region 600 and then flows into the opening 62a. For this reason, the suction efficiency of the suction fan 62 is improved.

  Since the air guide part 63 has the second partition plate 502 sandwiched in the gap between the first bar-like member 633 and the second bar-like member 632, the part where the placement part 631 and the first bar-like member 632 are formed is a fan arrangement. A portion where the second bar-shaped member 632 is formed is disposed in the region 600 and is disposed in the dust collection unit 900. The dust collector 900 is provided with a filter 52 that is in contact with the second rod-shaped member 632. Since the second rod-shaped member 632 is provided, the filter 52 is prevented from coming into close contact with the opening 63 a of the air guide portion 63. Thereby, a reduction in the suction force of the suction fan 62 is prevented.

(First exhaust port group and second exhaust port group)
Next, the first exhaust port group and the second exhaust port group will be described with reference to FIG. 4 and FIG. FIG. 10 is a cross-sectional view of the suction portion 5 cut along the line AA shown in FIG. The suction unit 5 rotates the suction fan 62 to generate an air flow from the suction head unit 2 and the suction port 38a toward the dust collection unit 900. The cleaner body 3 includes a first exhaust port group 19 and a second exhaust port group 20 that exhaust the airflow generated in the internal space of the housing 51 of the suction unit 5 to the outside. The first exhaust port group 19 and the second exhaust port group 20 are formed in the fan arrangement region 600. The air sucked from the dust collecting unit 900 by the suction fan 62 is discharged from the outer periphery of the suction fan 62 into the fan arrangement region 600. For this reason, the atmospheric pressure in the fan arrangement area 600 increases, and the air discharged into the fan arrangement area 600 is exhausted to the outside via the first exhaust port group 19 and the second exhaust port group 20.

  As shown in FIGS. 4 and 10, the first exhaust port group 19 and the second exhaust port group 20 are formed in different shapes. The first exhaust port group 19 is formed on the left side of the suction unit 5 (see FIG. 4A), and the second exhaust port group 20 is formed on the right side of the suction unit 5 (FIG. 4). (See (b)). The first exhaust port group 19 includes a plurality of first exhaust ports 19 a formed obliquely with respect to the thickness direction of the casing 51, and the second exhaust port group 20 is formed in the thickness direction of the casing 51. The plurality of second exhaust ports 20a are provided (see FIG. 5). As described above, the first exhaust port 19 a formed obliquely with respect to the thickness direction of the casing 51 is formed in a part of the casing 51. The first exhaust port group 19 and the second exhaust port group 20 are arranged around the suction fan 62. Thereby, the exhaust port rate of the air sucked into the housing 51 is improved. Further, since the first exhaust port 19a is formed obliquely with respect to the thickness direction of the casing 51, the first exhaust port can be provided when the user of the cleaner body 3 holds the suction part 5 in the right hand. The exhaust from the group 19 is prevented from being ejected toward the user.

(Rolling prevention part)
Next, the rolling prevention unit will be described with reference to FIGS. 3 and 4 again. As shown in FIG. 3B, the rolling prevention unit 32 is provided on a part of the back surface of the suction unit 5 (an example of the outer surface of the suction unit) to prevent the suction unit 5 from rolling. . The rolling prevention part 32 is provided along the direction in which the suction part 5 rolls and rotates. In the present embodiment, the suction part 5 is easy to roll in the short direction of the suction part 5. For this reason, the rolling prevention part 32 is formed by extending in the short direction of the suction part 5. In other words, the rolling prevention part 32 is formed by extending in the direction in which the side surfaces of the suction part 5 are arranged. The rolling prevention portion 32 is formed so as to protrude from the back surface of the suction portion 5 (see FIGS. 4A and 4B). The curvature in the short direction (an example of one direction) of the suction unit 5 on the contact surface 32a of the rolling prevention unit 32 that is in contact with the place (for example, the floor surface) where the suction unit 5 is placed is short of the suction unit 5 It is smaller than the curvature of the predetermined area of the suction part 5 in the same direction as the direction. Here, the predetermined area | region of the suction part 5 is a surface in which the rolling prevention part 32 is formed, and a back surface corresponds in this embodiment.

  The suction part 5 has an outer surface that is formed into a curved surface as a whole in consideration of the improvement of the feel of the user of the cleaner 1 and the design. For this reason, the back surface of the suction part 5 in which the rolling prevention part 32 is formed is also formed in a curved surface shape. The contact surface 32a of the rolling prevention unit 32 has the above-described curvature smaller than the back surface of the suction unit 5 provided with the rolling prevention unit 32. For this reason, when the suction part 5 is placed on the floor with the back side facing the floor, the contact part where the suction part 5 comes into contact with the floor surface has a lower rolling prevention part 32 than the case where the rolling prevention part 32 is not formed. If formed, it becomes flatter. Thereby, the suction part 5 becomes difficult to roll because the rolling prevention part 32 is formed.

[Configuration related to suction unit control]
(Control board)
As a configuration related to the control of the suction unit, the control board will be described with reference to FIG. 5 again. As shown in FIG. 5, the control board 70 that controls the entire vacuum cleaner 1 is disposed adjacent to the motor placement unit 601. The control board 70 is attached to the board attachment portion 701 and is disposed in the internal space of the housing 51. The substrate attachment portion 701 includes a first substrate support member 701a provided on the gripping portion 21 side and a second substrate support member 701b provided on the first partition plate 501 side. The first substrate support member 701 a and the second substrate support member 701 b are formed integrally with the housing 51. The first substrate support member 701a is formed integrally with the first arrangement member 601a. The second substrate support member 701b is formed integrally with the first partition plate 501.

  The first substrate support member 701 a and the second substrate support member 701 b are formed in a groove shape that is slightly wider than the thickness of the control substrate 70. One end of the control board 70 is sandwiched in the groove of the first substrate support member 701a, and the end opposite to the one end of the control board 70 is sandwiched and supported in the groove of the second substrate support member 701b. Yes. The board mounting portion 701 is configured to hold the control board 70 in the internal space of the housing 51 with the opposite end portions of the control board 70 interposed therebetween.

(Dust detector)
The suction unit 5 includes a circuit board 72 disposed in the vicinity of the boundary between the pipe connection unit 38 and the dust collection unit 900, and a light emitting element 73 and a light receiving element 74 disposed to face each other with the pipe connection unit 38 interposed therebetween. . The light emitting element 73 and the light receiving element 74 are connected to the circuit board 72. The light emitting element 73, the light receiving element 74, and the circuit board 72 constitute a dust detection unit. The light receiving element 74 is configured to receive light emitted from the light emitting element 73. The dust passing through the pipe connection portion 38 may block light emitted from the light emitting element 73 by passing between the light emitting element 73 and the light receiving element 74. Then, the light receiving element 74 cannot receive the light from the light emitting element 73 and cannot transmit a detection signal based on the received light to the circuit board 72. The predetermined circuit provided on the circuit board 72 detects the amount of dust passing through the pipe connecting portion 38 based on the detection signal transmitted from the light receiving element 74 and outputs the detection result to the control board 70. Yes. The light emitting element 73 and the light receiving element 74 are disposed in a through-hole provided in the side wall of the pipe connection portion 38, and are not disposed in the internal space 38 b of the pipe connection portion 38. For this reason, dust passing through the internal space 38 b of the pipe connection portion 38 is difficult to adhere to the light emitting surface of the light emitting element 73 and the light receiving surface of the light receiving element 74. Thereby, the dust detection part can detect dust stably and accurately.

(Wiring placement section)
As shown in FIG. 5, a space 33 a that communicates with the internal space of the housing 51 is formed in the wiring placement portion 33 on the internal space side of the housing 51. The space 33 a communicates with the internal space of the housing 51 at both ends on the short side of the wiring arrangement portion 33. In the space 33a, wiring for connecting the circuit board 72 and the control board 70 is arranged. Thereby, the control board 70 can supply electric power to the drive circuit provided on the circuit board 72. In addition, the circuit board 72 can transmit a signal based on the detected amount of dust to the control board 70. The vacuum cleaner body 3 can connect the control board 70 and the circuit board 72 that are arranged apart from each other by wiring while avoiding contact with the suction fan 62 and the motor 61 housed in the internal space of the casing 51.

(Dust detection display)
The suction unit 5 includes a dust detection display unit 35 provided between the dust collection unit cover 17 and the grip unit 21. The dust detection display unit 35 is provided to irradiate the light of the first light emitting unit 71 that emits light according to the amount of dust sucked by the suction unit 5 detected by the dust detection unit. The 1st light emission part 71 is comprised by the several light emitting element which light-emits a different color. The plurality of light emitting elements are, for example, bullet-type light emitting diodes. The dust detection display unit 35 includes a light diffusion unit 350 and a light reflection unit 351 disposed adjacent to the light emitting surface of the first light emitting unit 71. A control circuit (not shown) provided on the control board 70 causes one of the plurality of light emitting elements to emit light according to the amount of dust sucked by the suction unit 5. The light diffusion unit 350 diffuses and transmits the light emitted from the first light emitting unit 71 to the outside.

  Here, schematic configurations of the light diffusing unit 350 and the light reflecting unit 351 will be described with reference to FIGS. 11 to 14. FIG. 11 is a perspective view of the light diffusing unit 350. FIG. 12 is an orthographic view of the light diffusing unit 350. In the upper part of FIG. 12, a plan view of the light diffusing unit 350 is shown. In the middle part of FIG. 12, a left side view, a front view, and a right side view of the light diffusing unit 350 are shown in this order from the left. The bottom view of the light diffusing unit 350 is shown in the middle and lower stages. Note that the rear view of the light diffusing unit 350 is substantially the same as the front view of the light diffusing unit 350, and is not shown. FIG. 13 is a perspective view of the light reflecting portion 351. FIG. 13 is an orthographic view of the light reflecting portion 351. In the upper part of FIG. 13, a plan view of the light reflecting part 351 is illustrated, and in the middle part of FIG. 13, the left side view, front view, right side view, and rear view of the light reflecting part 351 are illustrated in this order from the left. In the lower part of FIG. 13, a bottom view of the light reflecting portion 351 is shown.

  As shown in FIGS. 11 and 12, the light diffusing unit 350 includes a first diffusing plate 350a and a second diffusing plate 350b that are arranged to face each other with a predetermined gap, and a first diffusing plate 350a and a second diffusing plate 350b.

[Mode of vacuum cleaner during storage and charging]
Next, with reference to FIGS. 1 and 3 to FIG. 5, FIG. 15 and FIG. 5 show the configuration of the vacuum cleaner during storage and charging, and the detailed configuration of the wall-mounted component 8 used during storage and charging of the vacuum cleaner. 16 will be described.

(Aspect of vacuum cleaner during storage and charging)
In the vacuum cleaner 1 according to the present embodiment, the vacuum cleaner main body 3 and the wall-mounted component 8 attached to the wall cooperate to form an aspect during storage and charging. As described above, the vacuum cleaner 1 is leaned against the leaning portion (the wall α in FIG. 1) in a state where the contact portion 31 is in contact with the wall placing component 8. The vacuum cleaner 1 has a state holding unit 40 that holds a state where the vacuum cleaner 1 is leaned on the hanging portion. The state holding unit 40 is provided separately in the vacuum cleaner main body 3 and the wall placing component 8. The state holding unit 40 is configured to lean the vacuum cleaner main body 3 in cooperation with the first holding member 40a (see FIG. 5) provided in the contact portion 31 and the first holding member 40a provided in the wall-standing component 8. And a second holding member 40b (see FIG. 15) that holds the unit in a leaning state. In the present embodiment, the first holding member 40 a is a magnet disposed in the contact portion 31 on the inner space side of the housing 51, and the second holding member 40 b is in contact with the contact portion 31 of the wall-standing component 8. It is the ferromagnetic body formed in the thin plate shape arrange | positioned at the back surface side of the surface to perform. When the vacuum cleaner main body 3 is brought into contact with the wall-mounted component 8 and leaned against the standing portion, the first holding member 40a and the second holding member 40b adhere to each other due to the magnetic force of the first holding member 40a. Thereby, the state holding | maintenance part 40 can be hold | maintained in the state which leaned the vacuum cleaner main body 3 on the to-be-rested part.

(Contact part)
As shown in FIG. 3B, the contact portion 31 includes a convex portion 31a that protrudes from the back surface of the suction portion 5 and a plurality of (two in this example) protruding portions 31b that protrude from the convex portion 31a. Yes. The 1st holding member 40a is arrange | positioned in the convex part 31a (refer FIG. 5). The protruding portion 31 b is formed in a thin plate shape that extends in the same direction as the extending direction of the rolling prevention portion 32. Even if the cleaner body 3 is laterally displaced in the left-right direction when the cleaner body 3 is brought into contact with the wall-mounted part 8 and leaned against the hanging part, the protrusion 31b is provided around the recess 81 of the wall-mounted part 8. Since it catches on the frame part 82 (it mentions later for details), the horizontal displacement of the cleaner body 3 is prevented. Further, the protrusion 31b can come into contact with the floor surface when the back surface of the suction unit 5 is placed on the floor with the back surface facing the floor surface. The contact surface (side surface of the protrusion 31b) where the protrusion 31b contacts the floor is formed flat. Thereby, the protrusion part 31b can prevent the suction part 5 from rolling together with the rolling prevention part 32.

  The contact portion 31 is provided with a screwing portion 31c for screwing the first housing member 51a and the second housing member 51b to each other with a screw N1.

(Configuration of wall-mounted parts)
Next, a schematic configuration of the wall placing component 8 will be described. FIG. 15 is an exploded perspective view of the wall placing component 8. FIG. 16 is an orthographic view of the wall-mounting part 8. In the upper part of FIG. 16, a plan view of the wall-mounting part 8 is shown, and in the middle part of FIG. A front view, a right side view, and a rear view are shown in this order, and a bottom view of the wall mounting component 8 is shown in the lower part of FIG.

  As shown in FIG. 15, the wall-mounting component 8 includes a facing member 8 a disposed to face the cleaner body 3, a second holding member 40 b disposed on the back side of the facing member 8 a, and a second holding member. And an adhesive sheet 8b disposed on the back side of 40b.

  The 2nd holding member 40b which comprises the state holding | maintenance part 40 has a thin plate square shape. The second holding member 40b has a size that covers almost the entire back surface of the opposed member 8a. Long semicircular cutouts 401a and 401b are formed on a pair of opposing sides of the second holding member 40b, respectively. The notches 401a and 401b are used for positioning when the second holding member 40b is superimposed on the opposed member 8a. A plurality (four in this example) of through holes TH1, TH2, TH3, TH4 are formed in the second holding member 40b. A screw (not shown) for screwing the second holding member 40b to the opposed member 8a is inserted into the through holes TH1, TH2, TH3, TH4.

  As shown in FIGS. 15 and 16, the wall-mounting component 8 includes a frame portion 82 that is provided so as to surround the recess 81 and protrudes toward the side where the cleaner body 3 is disposed. The concave portion 81 and the frame portion 82 are formed in the opposed member 8a. A frame portion 82 is formed at the peripheral edge of the opposed member 8a. The opposed member 8a is formed with a recess 81 that is surrounded by the frame portion 82 and occupies the central region. The height of the concave portion 81 from the end portion on the side where the second holding member 40b is arranged is lower than the height of the frame portion 82 from this end portion. For this reason, the recessed part 81 is recessed with respect to the frame part 82 in the to-be-opposed member 8a. The recess 81 is formed in a flat shape. The contact part 31 formed in the suction part 5 is disposed on the inner peripheral side of the frame part 82 and in contact with the concave part 81. The second holding member 40 b is disposed on the entire back surface of the recess 81. For this reason, as long as the user who wants to store or charge the vacuum cleaner 1 makes the contact part 31 contact the recess 81 without being aware of the position in the recess 81, the magnetic force of the first holding member 40a causes the first. The one holding member 40a and the second holding member 40b stick together. Thereby, the state holding | maintenance part 40 can hold | maintain the state by which the cleaner main body 3 was leaned on the to-be-rested part, ie, the state at the time of the accommodation of the cleaner 1, and charge. Thus, the vacuum cleaner 1 can be stored or charged by a very simple operation.

  The frame portion 82 includes a first side wall 82a, a second side wall 82b disposed opposite to the first side wall 82a, and a third side wall 82c disposed between one end of the first side wall 82a and one end of the second side wall 82b. And a fourth side wall 82d disposed between the other end of the first side wall 82a and the other end of the second side wall 82b and opposed to the third side wall 82c. The first side wall 82a, the second side wall 82b, the third side wall 82c, and the fourth side wall 82d are integrally formed.

  As shown in FIG. 16, the first side wall 82 a and the second side wall 82 b have a convex shape in which the height from the surface of the concave portion 81 that contacts the contact portion 31 is highest at the central portion in the longitudinal direction. The first side wall 82a and the second side wall 82b have a bank shape. The first side wall 82a and the second side wall 82b have a drum bridge shape. The surface of the 1st side wall 82a and the 2nd side wall 82b which opposes the cleaner body 3 is formed in the curved surface shape. The lateral displacement of the vacuum cleaner main body 3 in the left-right direction is prevented by mainly contacting the first side wall 82a and the second side wall 82b of the frame portion 82 with the protruding portion 31b.

  As shown in FIGS. 15 and 16, the wall placing component 8 is formed on the first side wall 82 a and the second side wall 82 b which are part of the frame portion 82, and extends in the width direction of the first side wall 82 a and the second side wall 82 b. A first groove 83a and a second groove 83b are provided. The first groove 83a is formed near the fourth side wall 82d of the first side wall 82a. The second groove 83b is formed near the fourth side wall 82d of the second side wall 82b. The 1st groove part 83a and the 2nd groove part 83b function as a cable receiving part received in the state which let the power cable for charging the rechargeable battery provided in the suction part 5 pass. The contact portion 31 provided in the suction portion 5 is provided in the vicinity of the power connector 39 (see FIG. 4A). For this reason, the wall-mounting component 8 disposed to face the contact portion 31 is disposed in the vicinity of the power connector 39 when the cleaner body 3 is leaned against the leaning portion. Accordingly, when the power cable is connected to the power connector 39 after passing through the first groove 83a and the second groove 83b, the length of the power cable from the power connector 39 to the second groove 83b is the left side surface of the suction portion 5. The length will be about. The load that the power connector 39 receives from the power cable is a weight corresponding to the length of the power cable from the power connector 39 to the second groove 83b. On the other hand, when the power cable is not passed through the first groove 83a and the second groove 83b, the load that the power connector 39 receives from the power cable is the weight of the entire length of the power cable. For this reason, when the power cable is passed through the first groove 83a and the second groove 83b and then connected to the power connector 39, the power cable is not passed through the first groove 83a and the second groove 83b. Compared with the case of connection, the load received by the power connector 39 from the power cable is reduced. Thereby, deterioration of the power connector 39 is prevented.

  As shown in FIG. 16, an adhesive sheet 8b is provided on the back side of the opposed member 8a. The wall-mounting component 8 can be attached to the standing portion by the adhesive force of the adhesive sheet 8b. For this reason, the wall-mounting component 8 can be easily attached to the standing portion. The wall placing component 8 includes a first through hole 84a formed in the first side wall 82a and a second through hole 84b formed in the second side wall 82b. The wall-mounting component 8 can be screwed to the standing portion by screws inserted into the first through hole 84a and the second side wall 82b.

  As described above, the vacuum cleaner 1 according to the present embodiment is attached to the vacuum cleaner body 3 and the hanging portion on which the vacuum cleaner body 3 is leaned, and when the cleaner body 3 is leaned on the hanging portion, the cleaner body 3 and the wall-mounting component 8 disposed to face the contact portion 31. Thereby, the cleaner 1 can be accommodated only by leaning on the to-be-rested portion in a state where the cleaner main body 3 is in contact with the wall-standing component 8. Further, the vacuum cleaner 1 can be constructed by leaning the vacuum cleaner main body 3 against the wall-mounted component 8 and leaning it on the hanging portion and connecting the power connector 39 and a socket to which commercial power is supplied via a power cable. The rechargeable battery can be charged. Thereby, the operativity of the cleaner 1 at the time of accommodation or charge is improved.
