JP 2017-60590 A

  By the way, there is known a vacuum cleaner including a separation unit having a frustum-shaped filter that narrows from the upstream side to the downstream side of the air flow. The bottom of the frustum filter on the small diameter side is open. A part of the bottom portion on the large diameter side of the frustum-shaped filter is closed, and the remaining portion (substantially the central portion of the bottom portion on the large diameter side) is opened. Here, the large-diameter side opening of the frustum-shaped filter is referred to as “filter suction port”, and the small-diameter side opening is referred to as “filter discharge port”.

  The separation unit having this type of filter applies negative pressure to the filter surface corresponding to the frustum-shaped side surface and the discharge port, and sucks in air containing dust from the suction port. The air sucked into the separation part contains dust. Most of the dust sucked into the separation part goes straight from the suction port to the discharge port and flows out of the separation part. A part of the air sucked into the separation part goes straight from the suction port of the filter to the discharge port and flows out of the separation part. The remainder of the air sucked into the separation part flows out of the filter surface.

  A part of the dust flows in the air flowing out from the filter surface and adheres to the inner surface of the filter surface. Such dust remains in the separation part and is gradually accumulated.

  Therefore, it is preferable that this type of separation portion has a lid structure that can fully open the bottom portion on the large diameter side. This lid closes a part of the bottom of the large diameter side of the filter and fully closes with the remaining part opened. Moreover, the inside of the separation part can be cleaned by opening the lid.

Arise. The gap between the lid and the filter leaks air containing dust from the separation part. If air containing dust leaks out from the separating portion, not only the suction work of the vacuum cleaner is reduced, but also dust is scattered around.

  Then, an object of this invention is to provide the vacuum cleaner which can fully fully close the cover body which opens and closes a isolation | separation part, when a dust container is attached to the cleaner body.

  In order to solve the above problems, an electric vacuum cleaner according to an embodiment of the present invention is provided in a vacuum cleaner body having a dust container holding part, a dust container detachable from the dust container holding part, and the vacuum cleaner body.

The relatively light dust separated by the filter unit 59 is called fine dust. That is, the filter unit 59 separates fine dust from the air passing through the first separation unit 58. The filter chamber 62 is a second dust collection chamber in which fine dust separated by the filter unit 59 is accumulated. The coarse dust collection chamber 61 and the filter chamber 62 are collectively referred to as a dust collection chamber 63.

  The dust-containing air flowing into the dust container 13 from the main body connection port 18 is separated into coarse dust and other (air containing fine dust) by the first separation unit 58. The separated coarse dust is accumulated in the coarse dust collection chamber 61. The air containing fine dust separated by the first separation unit 58 flows into the filter chamber 62. The air that has flowed into the coarse dust collection chamber 61 also flows into the filter chamber 62. The air containing fine dust that has flowed into the filter chamber 62 is separated into fine dust and air by the filter unit 59. The separated fine dust is captured by the filter unit 59 and accumulated in the filter chamber 62. The clean air that has passed through the filter portion 59 is sucked into the electric blower 15 through the communication air passage 56.

  The first separation unit 58 includes a nozzle unit 65 connected to the main body connection port 18 and a frustum-shaped primary filter unit 66 connected to the nozzle unit 65.

  The nozzle portion 65 extends into the container body 68 from a suction port 68 a of the container body 68 corresponding to the outer shell of the dust container 13.

  The primary filter unit 66 includes a primary filter frame 71 and a first mesh filter 72.

  The primary filter frame 71 is provided on the inner surface of the container main body 68. The primary filter frame 71 extends in a tapered shape along the center line of the main body connection port 18, that is, substantially the center line C of the cleaner body 7, with the dust container 13 mounted on the main body case 11. . The bottom of the large diameter is in contact with the inner surface of the container body 68, and the bottom of the small diameter has a coarse dust discharge port 73 connected to the coarse dust collection chamber 61 of the dust collection portion 55. The diameter of the bottom of the large diameter is larger than the opening diameter of the suction port 68a. The center line of the coarse dust discharge port 73 is substantially along the center line of the suction port 68a and substantially along the center line of the main body connection port 18. The coarse dust outlet 73 corresponds to the inlet of the dust collection chamber 63.

  The first mesh filter 72 is provided on the side surface of the primary filter frame 71. A relay air passage 75 connected to the filter chamber 62 is defined outside the first mesh filter 72.

  The first separation unit 58 becomes negative pressure by the flow of air sucked into the electric blower 15 through the first mesh filter 72 and the flow of air sucked into the electric blower 15 through the coarse dust discharge port 73.

  The coarse dust collection chamber 61 accumulates relatively heavy dust separated by the first separation unit 58. The coarse dust collection chamber 61 is a part of the air path of the air sucked into the electric blower 15. The coarse dust collection chamber 61 is connected to the coarse dust discharge port 73 of the first separation unit 58. The coarse dust collection chamber 61 is also connected to the filter chamber 62. The coarse dust collection chamber 61 is disposed on the center line of the main body connection port 18, that is, substantially on the center line C of the cleaner body 7.

  A partition wall 77 having a plurality of coarse dust collection chamber outlets 76 is provided between the coarse dust collection chamber 61 and the filter chamber 62 in which the filter portion 59 is accommodated. The partition wall 77 is a part of the wall of the dust collection chamber 63. A second mesh filter 78 is provided at the coarse dust collection chamber outlet 76 of the partition wall 77. The coarse dust collection chamber 61 is an upstream air passage that guides air containing dust to the second mesh filter 78.

  Further, the coarse dust collection chamber 61 is expanded in a direction away from the electric blower 15, in other words, in a direction approaching the filter unit 59. That is, the coarse dust collection chamber 61 has an expansion portion 79 in the vicinity of the second mesh filter 78 in which the air passage cross-sectional area rapidly increases. A partition wall 77 having a plurality of coarse dust collection chamber outlets 76 is provided between the expansion portion 79 and the filter chamber 62.

  The second mesh filter 78 filters and separates dust from air containing coarse dust, which is sucked into the coarse dust collection chamber 61 by negative pressure. The second mesh filter 78 prevents coarse dust from flowing out of the coarse dust collection chamber 61 into the filter chamber 62. The second mesh filter 78 compresses the dust accumulated in the coarse dust collection chamber 61 by the flow of air passing therethrough. The second mesh filter 78 has substantially the same mesh as the first mesh filter 72. Temporarily, fine dust that has not been separated by the first separation unit 58 and has flowed into the coarse dust collection chamber 61 flows into the filter chamber 62 through the second mesh filter 78, or is filtered within the coarse dust collection chamber 61. It is captured by the coarse dust compressed.

  The filter part 59 filters and separates dust, in particular fine dust passing through the first separation part 58, from the dust-containing air (dust-containing air) sucked by the negative pressure generated by the electric blower 15. The filter unit 59 includes a pair of filters 81 and 82 facing each other, and a secondary filter frame 83 that maintains and supports the shape of the pair of filters 81 and 82.

  The pair of filters 81 and 82 face the downstream side. Each of the filters 81 and 82 filters and separates dust from the air containing the dust sucked into the dust container 13. The meshes of the filters 81 and 82 are finer than the first mesh filter 72 of the first separator 58 and the second mesh filter 78 of the coarse dust collection chamber 61. The filters 81 and 82 are non-woven fabrics, for example. The fine dust trapped by the filters 81 and 82 includes dust that can pass through the first mesh filter 72 and the second mesh filter 78.

  One of the filters 81 and 82 (filter 81) is directly exposed to the air flowing into the filter chamber 62, and the other of the filters 81 and 82 (filter 82) goes around one of the filters 81 and 82 (filter 81). Exposed to the air. That is, the filter 81 faces the relay air passage 75 that connects the first separation unit 58 and the filter unit 59, and faces the coarse dust collection chamber outlet 76 that connects the coarse dust collection chamber 61 and the filter chamber 62. . The filter 82 is hidden by the filter 81 and is disposed at a location where it cannot be seen from the relay air passage 75 and the coarse dust collection chamber outlet 76.

  The pair of filters 81 and 82 are pleated filters having fold lines (ridge lines 81a and 82a) having substantially the same width (interval) and the same depth.

  The filter 81 facing the relay air passage 75 and the coarse dust collection chamber outlet 76 may have a fold that is wider and shallower than the filter 82. Since the filter 81 faces the relay air passage 75 and the coarse dust collection chamber outlet 76, the dust passing through the first separation portion 58 and the dust flowing out from the coarse dust collection chamber 61, that is, fine dust, are first filtered. 81 is sprayed. The filter 81 captures fine dust and gradually clogs. As the filter 81 is clogged, fine dust sprayed on the filter 81 from the relay air passage 75 and the coarse dust collection chamber outlet 76 goes around the filter 82. Then, clogging of the filter 82 starts. That is, the filter 81 is more easily clogged than the filter 82. In other words, dust is more likely to adhere to the filter 81 than the filter 82. Therefore, by making the folds of the filter 81 wider and shallower than the filter 82, the dust can be easily removed from the filter 81 to which dust is more likely to adhere.

  The filters 81 and 82 may have a polytetrafluoroethylene (PTFE, so-called Teflon (registered trademark)) film on the upstream surface so that the attached dust can be easily removed. Further, only the filter 81 that is more easily clogged than the filter 82 may have a polytetrafluoroethylene film on the upstream surface.

  The secondary filter frame 83 supports the pair of filters 81 and 82 facing each other and spaced apart. A space defined by the secondary filter frame 83 and the pair of filters 81 and 82 corresponds to an air path on the downstream side of the filter unit 59. The internal space of the filter unit 59 is connected to the communication air passage 56. The secondary filter frame 83 is disposed on both sides of the filter 81 and has a secondary filter outlet 85 connected to the communication air passage 56. The secondary filter outlet 85 allows the air that has passed through the filters 81 and 82 to flow out to the communication air passage 56.

  The filter chamber 62 is adjacent to the coarse dust collection chamber 61. The filter chamber 62 functions as a fine dust collection chamber that accumulates fine dust captured by the filter unit 59 by filtration and separation. The fine dust passing through the first mesh filter 72 and the second mesh filter 78 is captured by a pair of finer filters 81 and 82 and accumulated in the filter chamber 62. That is, the dust collection chamber 63 (the coarse dust collection chamber 61 and the filter chamber 62) is disposed on the upstream side of the filters 81 and 82.

  The filter chamber 62 is a part of the air path of the air sucked into the electric blower 15. The filter chamber 62 is connected to the relay air passage 75. The filter chamber 62 is also connected to the coarse dust collection chamber 61.

  The communication air passage 56 is a plurality of air passages 56 a and 56 b that guide the air flowing out from the separation unit 54 to the electric blower 15. That is, the communication air passage 56 is branched into a plurality and reaches the electric blower 15. The communication air passage 56 is divided into, for example, two air passages 56a and 56b. A plurality of, for example, two air passages 56 a and 56 b sandwich a suction port 68 a that guides air to the separation unit 54. The two air passages 56a and 56b have substantially the same air passage cross-sectional area S. The two air passages 56 a and 56 b have a shape that is plane-symmetric with respect to a plane that includes the rotation center line of the fan of the electric blower 15. In other words, the plurality of air passages 56a and 56b are biased toward the edge side with respect to the center of the first mesh filter 72, the second mesh filter 78, and the filter portion 59 and are separated from each other. The two air passages 56 a and 56 b gather at the end of the communication air passage 56 connected to the electric blower 15 and merge. In other words, the two air passages 56 a and 56 b are connected to the electric blower 15 via the collective air passage 56 c of the communication air passage 56. Note that the communication air passage 56 may be branched into three or more. In other words. The communication air passages 56 are a plurality of downstream air passages that guide the air passing through the first mesh filter 72, the second mesh filter 78, and the filter unit 59 to the electric blower 15.

  Coarse dust having a relatively large mass in the dust-containing air flowing from the nozzle portion 65 to the first separation portion 58 travels straight from the nozzle portion 65 to the coarse dust discharge port 73 by an inertial force and is sent to the coarse dust collection chamber 61. . Dust (coarse dust) flowing into the coarse dust collection chamber 61 from the coarse dust discharge port 73 is accumulated in the coarse dust collection chamber 61. On the other hand, fine dust and air having a relatively small mass out of the dust-containing air flowing from the nozzle portion 65 to the first separation portion 58 spread radially from the nozzle portion 65 and are provided on the side surface of the primary filter frame 71. It passes through the mesh filter 72 and flows into the filter chamber 62 via the relay air passage 75. A part of the air also flows into the coarse dust collection chamber 61 together with the dust (coarse dust) flowing into the coarse dust collection chamber 61 from the coarse dust discharge port 73. The air flowing into the coarse dust collection chamber 61 passes through the second mesh filter 78 and flows into the filter chamber 62. Fine dust contained in the air that flows into the filter chamber 62 through the first mesh filter 72 or the second mesh filter 78 is filtered and separated by the filter unit 59 and captured by the surfaces of the pair of filters 81 and 82. The clean air that passes through the filters 81 and 82 is sucked into the electric blower 15 through the communication air passage 56. At this time, clean air is temporarily divided into a plurality of air passages 56 a and 56 b, and collected and sucked into the electric blower 15.

  The container main body 68 partitions the dust collection chamber 63, that is, the coarse dust collection chamber 61 and the filter chamber 62. The first separation unit 58 and the communication air passage 56 of the separation unit 54 are disposed between the filter unit 59 and the electric blower 15 and are provided side by side. In other words, the separation unit 54, the communication air passage 56, and the electric blower 15 are arranged in this order.

  The pair of wheels 12 includes the electric blower 15, the separation unit 54 (the first separation unit 58 and the filter unit 59), the dust collection unit 55 (the coarse dust collection chamber 61 and the filter chamber 62), and the communication air passage 56. It is sandwiched.

  The first separation unit 58 is disposed at the center in the width direction of the main body case 11, the filter unit 59 is biased to one side of the main body case, for example, the right side, and the electric blower 15 is connected to the other side of the main body case 11. It is biased to the side, for example the left side.

  The container lock mechanism 51 includes an operation unit 91 at a portion exposed to the outside of the cleaner body 7 in a state where the dust container 13 is accommodated in the dust container chamber 47 of the cleaner body 7. The operation unit 91 is an input unit for releasing the container lock mechanism 51. The operation unit 91 receives a force for detaching the claw portion 52 from the claw receiving portion 53.

  The legs 57 are provided on the outer surface of the dust guide surface 93 of the container main body 68 that extends from the coarse dust discharge port 73 to the extended portion 79 of the coarse dust collection chamber 61. The leg 57 swings between a storage position along the outer surface of the dust guide surface 93 and a use position for allowing the dust container 13 to stand on its own. The leg 57 can also be used as a handle for the dust container 13.

  The legs 57 receive a force for pushing out the dust container 13 generated by the pushing force generation unit 49 in a state where the dust container 13 is stored in the dust container chamber 47. A torsion spring (not shown) is provided between the leg 57 and the dust container 13. This torsion spring generates a force for moving the leg 57 to the use position in a state where the dust container 13 is taken out from the dust container chamber 47 and no external force is applied to the leg 57.

  In the process in which the dust container 13 is accommodated in the dust container chamber 47, the legs 57 are guided by the inner wall surface of the dust container chamber 47 and swing from the use posture to the storage posture. In a state where the dust container 13 is accommodated in the dust container chamber 47, the rod portion 49 a of the pushing force generating portion 49 comes into contact with the tip of the leg 57 in the accommodating posture, and a force for pushing out to the dust container 13 acts.

  When the lock of the container lock mechanism 51 is released in a state where the dust container 13 is accommodated in the dust container chamber 47, the dust container 13 is pushed out of the dust container chamber 47 by the pushing force of the pushing force generation unit 49. At this time, the leg 57 swings from the accommodation position to the use position while following the inner wall surface of the dust container chamber 47 by the spring force of the torsion spring. The leg 57 in the use posture supports the dust container 13 taken out from the cleaner body 7 in a self-supporting state (a state in which the left end portion is downward when viewed in a direction in which numbers can be read in FIG. 6).

  The secondary battery 17 surrounds the coarse dust collection chamber 61. That is, the plurality of unit cells 17 a included in the secondary battery 17 are arranged along the inner surface of the cylindrical rear half of the main body case 11 and surround the coarse dust collection chamber 61.

  Next, the 1st separation part 58 of the vacuum cleaner 1 which concerns on this embodiment is demonstrated.

  FIG. 7 is a partial perspective view of the primary dust container of the vacuum cleaner according to the embodiment of the present invention.

  FIG. 8 is a side view of the first separation portion of the vacuum cleaner according to the embodiment of the present invention.

  FIG. 9 is a cross-sectional view of the electric vacuum cleaner according to the embodiment of the present invention.

  2 and 3, the opening / closing structure of the lid 101 of the first separation unit 58 is omitted for convenience of explanation.

  In addition to FIGS. 2 and 3, as shown in FIGS. 7 to 9, the vacuum cleaner 1 according to the present embodiment has a cone that narrows away from the connection port 18 a on the dust container chamber 47 side of the main body connection port 18. A trapezoidal first mesh filter 72, an openable / closable lid 101 that reduces the opening area of the bottom 72a on the large diameter side of the first mesh filter 72, a hinge 102 that supports the lid 101 so as to be openable / closable, and a lid 101 And a clip 103 that holds the container in a closed state.

  The first mesh filter 72 has an open bottom 72 a that leads to the connection port 18 a on the dust container chamber 47 side of the main body connection port 18, and a bottom 72 b that opens as a coarse dust discharge port 73 connected to the dust collection chamber 63. have. The bottom 72 b on the dust collection chamber 63 side has a smaller opening diameter than the bottom 72 a closed by the lid 101.

  The lid 101 closes or opens the bottom 72 a on the large diameter side of the first mesh filter 72. The lid 101 has a suction port 68 a of the container main body 68. In other words, the suction port 68 a is disposed at the bottom 72 a on the large diameter side of the first mesh filter 72. The lid 101 fluidly connects the main body connection port 18 and the first separation part 58 through the suction port 68a.

  The lid body 101 or the container body 68 is provided with a seal member 108 that is sandwiched between the lid body 101 and the container body 68 in a state where the lid body 101 is fully closed.

  The opening edge of the suction port 68a of the container main body 68 is inclined toward the moving direction (solid arrow I in FIG. 2) when the dust container 13 is mounted in the dust container chamber 47. Further, the opening edge of the connection port 18 a on the dust container chamber 47 side of the main body connection port 18 is inclined in conformity with the inclination of the suction port 68 a of the container main body 68. Specifically, the opening edge of the suction port 68a is inclined forward in the moving direction (solid arrow I in FIG. 2) when the dust container 13 is mounted in the dust container chamber 47. That is, the opening edge of the suction port 68a extends from the edge reaching the back side of the dust container chamber 47 toward the edge near the dust container insertion / extraction port 47a side of the dust container chamber 47 (that is, the inlet side of the dust container chamber 47). It protrudes so as to approach the inner wall surface of the chamber 47. On the other hand, the connection port 18 a of the main body connection port 18 is configured to move dust from the edge close to the dust container insertion / extraction port 47 a side of the dust container chamber 47 (that is, the inlet side of the dust container chamber 47) toward the inner edge of the dust container chamber 47. It is inclined so as to protrude into the container chamber 47.

  When the dust container 13 is attached to the dust container chamber 47 by the inclination of the opening edge of the suction port 68a of the container body 68 and the inclination of the opening edge of the connection port 18a of the body connection port 18, the suction port 68a and the connection port 18a Are pressed together and the gap between each other is more tightly closed.

  The hinge 102 is disposed ahead of the fastener 103 in the moving direction when the dust container 13 is mounted in the dust container chamber 47. In other words, in a state where the dust container 13 is mounted in the dust container chamber 47, the hinge 102 is disposed on the deeper side of the dust container chamber 47 than the retainer 103, and the retainer 103 is more dust in the dust container chamber 47 than the hinge 102. It is arranged on the container insertion / extraction port 47a side (that is, the inlet side of the dust container chamber 47). The hinge 102 and the fastener 103 sandwich the suction port 68a of the lid 101.

  The clasp 103 includes a receiving portion 105 provided on the dust container 13 side, and a hanging portion 106 provided on the lid body 101 side and hooked on the receiving portion 105 to hold the lid body 101 in a closed state. Yes. Further, the fastener 103 includes a plate body portion 107 extending from the lid body 101.

  The receiving part 105 and the hanging part 106 are engaged with each other and hold the lid 101 in a closed state. The hanging portion 106 is, for example, a claw or a hook, and the receiving portion 105 is, for example, a groove or a protrusion.

  The plate body portion 107 protrudes from the lid body 101 in a cantilever shape. The plate portion 107 protrudes in a cantilever shape in a direction away from the hinge 102, and has a free end portion at a portion farthest from the hinge 102. On the other hand, a fixed end portion of the plate body portion 107, that is, a portion connected to the lid body 101 is closest to the hinge 102. The plate part 107 elastically supports the hook part 106 on the lid 101. The hook portion 106 is hooked on the hook portion 106 or the hook is released when the plate body portion 107 is bent.

  The hanging part 106 is disposed in a part of the fastener 103 farthest from the hinge 102. That is, the hanging portion 106 is provided at the free end portion (tip portion) of the plate body portion 107.

  The dust container 13 can close the lid 101 by hanging the fastener 103. Usually, the dust container 13 is attached to the cleaner body 7 with the lid 101 closed. Further, the dust container 13 can open the lid 101 by releasing the hook of the fastener 103. By opening the lid 101, the inside of the first separation unit 58, that is, the inside of the frustum-shaped first mesh filter 72 is opened, and dust attached to the filter surface of the first mesh filter 72 can be cleaned. become.

  By the way, when the closure of the lid 101 is incomplete, a gap is generated between the lid 101 and the dust container 13. This gap communicates with the inside of the first separation portion 58. When the electric blower 15 is operated with a gap between the lid 101 and the dust container 13, air flows through the gap and the suction work rate of the vacuum cleaner 1 is wasted or air or dust is lost. Leaks out.

  Therefore, the vacuum cleaner 1 according to the present embodiment includes a mechanism for forcibly closing the lid 101 of the dust container 13 when the dust container 13 is attached to the cleaner body 7.

  FIG. 10 is a perspective view of the lid forcibly closing mechanism of the electric vacuum cleaner according to the embodiment of the present invention.

  FIG. 11 is a cross-sectional view of the lid forcibly closing mechanism of the electric vacuum cleaner according to the embodiment of the present invention.

  As shown in FIGS. 10 and 11, the vacuum cleaner 1 according to the present embodiment compulsorily closes the lid 101 of the dust container 13 when the dust container 13 is attached to the cleaner body 7. A lid closing part 111 is provided as a closing mechanism.

  The lid body closing portion 111 is provided in the dust container chamber 47, and closes the lid body 101 by contacting at least one of the lid body 101 and the fastener 103 in the process of attaching the dust container 13 to the dust container chamber 47. And the fastener 103 is fastened.

  The lid closing portion 111 is disposed closer to the dust container insertion / extraction port 47a side of the dust container chamber 47 (that is, the inlet side of the dust container chamber 47) than the connection port 18a of the main body connection port 18 on the dust container chamber 47 side. The lid closing part 111 pushes the lid 101 into the fully closed position as the dust container 13 moves in the direction in which the dust container 13 is mounted in the dust container chamber 47.

  The lid closing part 111 is a pair of ribs 112, for example. These ribs 112 are spaced apart as long as they reliably contact the lid body 101 and the fastener 103. The rib 112 protrudes from the inner surface of the dust container chamber 47 in the moving direction when the dust container 13 is mounted in the dust container chamber 47 (solid line arrow I in FIG. 10), that is, toward the back of the dust container chamber 47. Is big. The lid closing part 111 is in a state in which the dust container 13 is attached to the cleaner body 7, that is, the positional relationship in which the suction port 68a of the container body 68 is connected to the connection port 18a on the dust container chamber 47 side of the main body connection port 18. Then, at least one of the lid 101 and the clip 103 is strongly pressed against the container main body 68 and the hook 106 of the clip 103 is securely hooked on the receiving part 105.

  The lid closing part 111 is not limited to a rib-shaped protrusion, as long as it comes into contact with at least one of the lid 101 and the clip 103 and presses the lid 101 against the container main body 68. It may be a ledge (bump).

  The vacuum cleaner 1 according to the present embodiment closes the lid body 101 by contacting at least one of the lid body 101 and the clasp 103 in the process in which the dust container 13 is mounted in the dust container chamber 47, and the clasp And a lid closing part 111 for fastening 103. Therefore, the vacuum cleaner 1 can open the lid 101 and care for the first separation part 58. In addition, the vacuum cleaner 1 ensures that the lid 101 is securely closed even when the dust container 13 is mounted in the dust container chamber 47 without being completely closed, that is, forgotten to close. Closed, air and dust do not leak from the gap between the lid 101 and the dust container chamber 47.

  Moreover, the vacuum cleaner 1 according to the present embodiment includes a hinge 102 that precedes the fastener 103 in the moving direction when the dust container 13 is attached to the dust container chamber 47. Therefore, even when the vacuum cleaner 1 intentionally keeps the lid 101 open and the dust container 13 is attached to the dust container chamber 47, the vacuum cleaner 1 is forced to insert the dust container 13 into the dust container chamber 47. Can be directed to the wall surface of the dust container chamber 47, moved in the closing direction, and the lid body 101 can be reliably closed by the lid body closing portion 111.

  Furthermore, the vacuum cleaner 1 according to the present embodiment includes a plate body portion 107 that extends from the lid body 101 and has a hook portion 106 at the tip. Therefore, when the vacuum cleaner 1 closes the lid body 101 around the hinge 102, the hook portion 106 of the fastener 103 is directed to the hook portion 106 with a larger moment and can be securely fastened.

  Furthermore, the vacuum cleaner 1 according to the present embodiment has a suction port 68a of the container main body 68 that is inclined in the moving direction when the dust container 13 is mounted in the dust container chamber 47. Therefore, the vacuum cleaner 1 strongly closes both openings by strongly addressing the suction port 68a to the connection port 18a of the main body connection port 18 that opens in a direction crossing the moving direction when the dust container 13 is attached and detached. Can do.

  Moreover, the vacuum cleaner 1 according to the present embodiment includes the lid closing portion 111 that strongly pushes the lid 101 into the fully closed position as the dust container 13 moves in the direction in which the dust container 13 is attached to the dust container chamber 47. . Therefore, even if the vacuum cleaner 1 is not completely closed, that is, forgotten to close, the dust container 13 is attached to the dust container chamber 47 even if the lid 101 is not completely closed. It closes reliably, and it can prevent reliably that air and dust leak from the clearance gap between the cover body 101 and the dust container chamber 47. FIG.

  Furthermore, the vacuum cleaner 1 according to the present embodiment includes a dust container chamber 47 that accommodates the entire dust container 13. That is, when the vacuum cleaner 1 accommodates the dust container 13 in the dust container chamber 47, it is difficult to visually check whether or not the lid 101 is closed from the appearance of the cleaner body 7.
