Description

  The present invention relates to a vacuum cleaner including a dust collection case that can be attached to and detached from a vacuum cleaner body.

  Dust stored in the dust collection case when the opening / closing lid that opens and closes the opening of the case is opened to facilitate the discharge of dust collected in the dust collection case that has been removed from the vacuum cleaner body There is known a vacuum cleaner having a configuration in which the storage and collection means are protruded from the opening of the dust collection case (for example, see Patent Document 1).

  In the dust collection case described in this patent document 1, the dust containing collection means accommodated so that movement inside is urged | biased with the spring so that it may protrude from the opening part of a dust collection case. At the same time, the opening / closing lid is locked by the clamp so as to close the opening of the dust collecting case, thereby preventing the dust collecting means accommodated in the dust collecting case from moving in the protruding direction. It is configured as follows.

  Therefore, when the clamp is unlocked and the opening / closing lid is opened, the dust disposal port of the dust containing and collecting means expands and vigorously protrudes from the opening of the dust collecting case by the biasing force of the spring. Moreover, the protrusion is blocked by the drop-off preventing means when it has advanced to some extent, and a large impact is given at that time. Therefore, the dust in the dust collection case can be discharged to the outside at once.

JP 2008-380 (paragraphs 0012-0055, FIGS. 1 to 11)

  In the prior art, the dust in the collecting means is suddenly stopped after the dust containing and collecting means move vigorously as the clamp is released as described above, so that the dust in the collecting means is released at a stroke. There is a problem that it is easy to fly up and fly around. Therefore, in actual dust disposal, it is recommended that the operation of releasing the clamp be performed outdoors with a large garbage bag and a dust collection case inside. Is not easy to use.

  Accordingly, an object of the present invention is to provide a vacuum cleaner in which when the dust accumulated in the dust collection case is discharged, the discharged dust is difficult to fly up and fly up.

  In order to solve the above-mentioned problems, the present invention separates dust in the air that is detachable from a vacuum cleaner main body incorporating an electric blower and is sucked into the electric blower through a dust suction port of the vacuum cleaner main body. In a vacuum cleaner including a dust collection case that accumulates and collects, the dust collection case includes a case main body, a case lid, a guide member, and a dust separation member. The case body has an airflow inlet, a dust outlet, and an airflow outlet that communicate with the dust inlet. And the case cover which opens and closes a dust disposal port is provided in the case main body so that rotation is possible. The guide member is provided in the case body so as to partition the dust chamber in which the airflow inlet and the dust outlet face the case body, and to guide the dust-containing air sucked into the airflow inlet to the inner surface of the case lid. In addition, the dust separation member has a separation portion that is located on the opposite side of the guide member with the flow of dust-containing air drawn into the airflow inlet and toward the inner surface of the case lid in a state where the case lid is closed, A dust storage space is formed between the separation portion and the free end portion of the case lid, and the case lid is provided to face the inner surface of the lid. The dust separation member is characterized in that the dust chamber airflow that is reversed on the inner surface of the case lid and flows toward the airflow outlet is filtered and the dust separated by the filtration is stored in the dust storage space. .

  In the present invention, the dust-containing air sucked into the airflow inlet is guided to the inner surface of the case lid by the guide member, and after being reversed by the inner surface, is filtered by the dust separation member, The air is trapped by the dust separation member and stored in the dust storage space between the dust separation member and the case lid. On the other hand, the air that has passed through the dust separation member passes outside the dust collection case through the air flow outlet. Leaked. When throwing away the dust separated by filtration in the dust collection case and stored in the dust storage space, the dust collected in the dust storage space along with the opening of the case lid passes through the dust disposal opening. The case lid and the dust separating member that are drawn out and form a dust storage space face downward. Therefore, the dust accumulated between the dust separation member and the case lid can be discharged downward without giving a large momentum and impact for causing the accumulated dust to jump out.

  ADVANTAGE OF THE INVENTION According to this invention, when discharging | emitting the dust stored in the dust collection case, there exists an effect that the discharged | emitted dust can disperse and it can provide the vacuum cleaner which is hard to fly.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS.

  Reference numeral 1 in FIG. 1 indicates a vacuum cleaner. The vacuum cleaner 1 includes a vacuum cleaner body 2, an electric blower 7, a dust collection case 11 (see FIG. 4 and the like) that forms an upstream dust collector, and a filter (see FIG. 3) 61 that forms a downstream dust collector. And a dust suction air passage member 71.

  As shown in FIGS. 1 and 2, the cleaner body 2 is formed by attaching a cleaner body cover 4 to a cleaner body case 3. The vacuum cleaner main body 2 can move on a surface to be cleaned such as a floor surface of a building by rotation of wheels 5 (only one is shown) attached to both sides in the width direction of the rear part. The vacuum cleaner main body case 3 has a partition wall 3a (see FIG. 2) having air permeability at an intermediate portion in the front-rear direction. Due to the partition wall 3a, the inside of the cleaner body case 3 has a dust collector storage chamber 3b (see FIG. 2) on the front side (upstream side) of the partition wall 3a and an electrical component storage chamber (not shown) on the rear side (downstream side) of the partition wall 3a. It is divided into and.

  In the electrical component storage chamber, an electric blower 7, a control device that electrically controls the operation of the cord reel (not shown) and the electric blower 7, and the like are accommodated. The dust collecting chamber 3 b is provided on the upstream side of the electric blower 7 with reference to the air flow sucked into the electric blower 7. The upper end of the dust collector housing chamber 3b is opened.

  The rear end portion of the vacuum cleaner body lid 4 is pivotably connected to the upper surface side portion of the vacuum cleaner body case 3, and the upper end opening of the dust collector housing chamber 3 b is opened and closed by the rotation of the cleaner body lid 4. It has come to be. The cleaner body cover 4 has a hose connection port 4a (see FIG. 1).

  The dust collecting case 11 and the filter 61 to be described later can be attached to and detached from the dust collector housing chamber 3b of the cleaner body 2 through the upper end opening in a state in which the cleaner body lid 4 is opened. This is performed in a posture in which a frame wall 12c described later is substantially vertical. The dust collecting case 11 is accommodated in the dust collecting chamber 3b with the rear end opening edge of the frame wall 12c in contact with the front surface (upstream side surface) of the partition wall 3a, and is collected by a holding mechanism (not shown). The dust storage chamber 3b is held in a non-moving state.

  The dust collection case 11 includes a case main body 12, a case lid 24, a guide member 41, and a dust separation member 51.

  As shown in FIG. 6 and the like, the case body 12 includes a slanted wall 12a that is slanted forward and downward, a side wall 12b that is integrally connected to each of the left and right sides of the slanted wall 12a, and a rear side of the slanted wall 12a and the side wall 12b. And a frame wall 12c having a rectangular frame shape integrally formed on the side.

  The case main body 12 has an airflow inlet 14, a dust outlet 16, and an airflow outlet 18.

  The air flow inlet 14 is provided in the oblique wall 12a. The dust outlet 16 is surrounded by a slanted wall 12a, left and right side walls 12b, and a projecting wall 12d integrally projecting downward from the frame wall 12c and integrally continuing to the lower end of the side wall 12b. It is formed to open below. The dust outlet 16 is inclined so that the height position gradually increases from the rear end toward the front end. The air flow outlet 18 is surrounded by a frame wall 12c and is formed to open to the rear (downstream side) of the case body 12.

  As shown in FIGS. 2-6, the handle | steering-wheel 19 is integrally protrudingly provided by the upper surface of the frame wall 12c. The handle 19 is gripped by the user when the dust collecting case 11 is attached to and detached from the cleaner body 2 and when the dust collecting case 11 is carried. As shown in FIGS. 5 and 6, a downward projecting portion 20 is integrally projectingly provided at an intermediate portion in the longitudinal direction of the projecting wall 12 d. A wind-shielding wall portion 21 extending from the left and right side walls 12 b is provided on the lower side of the case body 12 in front of the protrusion 20. The lower end of the wind shielding wall 21 protrudes slightly below the opening of the dust outlet 16.

  The case lid 24 is pivotally attached to the case body 12 by a pivoting means, and can open and close the dust outlet 16. As shown in FIGS. 5 and 6, the pivot support means is provided integrally with a pair of pivot shafts 25 (only one is shown) provided integrally with the case lid 24 and the protruding wall 12 d of the case body 12. A pair of supported bearings 26 (only one is shown) is formed. The pivot means is provided on the periphery of the dust outlet 16, for example, on the rear side. Therefore, the case lid 24 can be rotated with the pivot means supporting the rear end portion as a fulcrum.

  The edge of the case lid 24 on the side of the pivoting means, for example, the rear edge 24a is engaged with the protrusion 20 when the case lid 24 is fully opened, so that the case lid 24 has its free end. The portion (tip portion) is positioned at a position (see FIG. 8) that faces substantially downward.

  As shown in FIG. 6 and the like, an annular sealing material 27 is attached to the inner surface of the peripheral portion of the case lid 24. The sealing material 27 is sponge-like and can be elastically deformed. When the case lid 24 is closed, the sealing material 27 is pushed by the walls surrounding the dust outlet 16 and is elastically deformed. Thereby, airtightness between the case main body 12 and the case lid 24 is maintained.

  A partition wall portion 24b that crosses the case lid 24 in the width direction is integrally formed at a portion of the case lid 24 on the side of the pivot means, for example, at the rear portion of the case lid 24. In a state where the case lid 24 is closed, the wind shield wall 21 can contact or approach the top surface of the partition wall 24b.

  The case lid 24 has a first air guide portion 24c and a second air guide portion 24d. The first air guide portion 24c is provided close to the pivot means, and is formed, for example, at a portion that is continuous with the top surface of the partition wall portion 24b. In other words, the first air guide portion 24c is a portion that is continuous to the front side with respect to the top surface of the partition wall portion 24b in a state where the case lid 24 is closed.

  The first air guide portion 24c is provided so as to be disposed almost directly below a guide member 41 described later in a state where the case lid 24 is closed. At the same time, the first air guiding portion 24c has an oblique shape that becomes lower toward the front end portion (free end portion) side of the lid when the case lid 24 is closed. As a result, the flow of the dust-containing air guided downward along the guide member 41 can be redirected toward the free end side of the case lid 24 at the first air guide portion 24c.

  The second air guiding portion 24 d is provided on the free end side of the case lid 24. The second air guide portion 24d has an oblique shape that becomes higher toward the free end side of the lid when the case lid 24 is closed. Thereby, the flow of the dust-containing air that flows downward along the inner surface of the case lid 24 can be redirected toward the upper side of the free end portion of the case lid 24 at the second air guiding portion 24d. .

  As shown in FIG. 3, a clamp mechanism 31 that holds the case lid 24 in a closed state is provided on one side wall 12 b of the case body 12. As shown in FIG. 9, the clamp mechanism 31 includes a clamp lever 32, a spring 33, an operation lever 34, and the like.

  The clamp cover 35 is screwed to the outer surface of the one side wall 12b, and a relief groove 35a is formed in the clamp cover 35 so as to open to the lower end thereof. A first lever pivot 36 is provided between the lower portion of the clamp cover 35 and the one side wall 12b, and the clamp lever 32 is rotatably supported by the first lever pivot 36. The lower end portion of the clamp lever 32 forms a hook portion 32a. The clamp lever 32 is urged by a spring 33 so that the hook portion 32a is positioned in the escape groove 35a.

  A second lever pivot 37 is provided between the upper portion of the clamp cover 35 and the one side wall 12b, and the operation lever 34 is rotatably supported by the second lever pivot 37. The upper end of the operation lever 34 protrudes above the clamp cover 35 and can be operated artificially. The lower end portion of the operation lever 34 is engaged with the upper end portion of the clamp lever 32, so that the clamp lever 32 is resisted against the spring 33 so that the hook portion 32 a is released from the escape groove 35 a through the operation of the operation lever 34. And can be rotated.

  Corresponding to the clamp mechanism 31, a locking claw portion 28 (see FIGS. 6 and 9) is integrally projected on the case lid 24. The engaging claw portion 28 can be inserted into and removed from the escape groove 35 a as the case lid 24 is opened and closed.

  Therefore, when the case lid 24 is rotated in the closing direction and the locking claw portion 28 is inserted into the escape groove 35a, the locking claw portion 28 is hooked on the hook portion 32a of the clamp lever 32. The lid 24 can be kept closed. Further, when the operation lever 34 is operated in the direction of the arrow in FIG. 9 in the closed state of the case lid 24, the clamp lever 32 is rotated against the spring 33, and its hook portion 32a is engaged with the locking claw portion 28. Removed from. Therefore, the case lid 24 can be opened downward by its own weight.

  As shown in FIGS. 4 and 5, the guide member 41 is provided in the case body 12 by partitioning the dust storage chamber 42. For example, the entire guide member 41 has air permeability. Therefore, in the present embodiment, the guide member 41 is formed by mounting the net filter 41b on the front surface (upstream side surface) of the lattice member 41a integrally having a cross that crosses vertically and horizontally in the frame portion.

  The guide member 41 is disposed along the vertical direction inside the rear portion of the case main body 12 so as to be continuous substantially above the windshield wall portion 21. The guide member 41 partitions the dust storage chamber 42 on the front side (upstream side) from the air flow outlet 18 on the rear side (downstream side). The air flow inlet 14 and the dust outlet 16 face the dust chamber 42.

  The guide member 41 is provided so as to guide the dust-containing air sucked into the airflow inlet 14 toward the inner surface of the case lid 24. Therefore, for example, as shown in FIG. 4, the central axis C of the airflow inlet 14 intersects the guide member 41 obliquely, and the angle between the upper portion of the guide member 41 and the central axis C is an acute angle with this intersection as a boundary. On the contrary, the angle between the lower portion of the guide member 41 and the central axis C is an obtuse angle at the intersection.

  In other words, the airflow inlet 14 is opposed to the upper region in the center in the width direction of the guide member 41 from the upper front side. Therefore, the dust-containing air that has passed through the airflow inlet 14 does not flow at a steep angle at the guide member 41, and can be smoothly guided toward the lower case lid 24 while suppressing the occurrence of turbulence. Alternatively, the air flow inlet 14 can be disposed above the guide member 41 so that the central axis C thereof is substantially parallel to the guide member 41. In this way, the air flow inlet 14 is more turbulent. Flow generation can be suppressed.

  As shown in FIGS. 4 to 7, the dust separating member 51 is provided on the case lid 24 so as to face the inner surface of the case lid 24 as described later.

  The dust separation member 51 is, for example, a flat plate-like separation portion 51a that forms the front portion of the dust separation member 51, and a dust separation by protruding integrally from both ends of the width direction (left and right direction in FIG. 6) of the separation portion 51a. It is formed by a pair of partition parts 51b that form the rear part of the member 51. The edge 51 c of the dust separation member 51 has a shape that can follow the inner surface of the case body 12.

  Each partition 51b has a flat plate shape, is bent at an obtuse angle with respect to the rear side of the separation part 51a, and has a length that contacts the guide member 41 in a state where the case lid 24 is closed. ing. A ventilation part 52 is provided between the partition parts 51b. The ventilation portion 52 is positioned at the center in the width direction of the case body 12 with the case lid 24 closed, and is opposed to the air flow inlet 14. Note that the dust separating member 51 can be formed only by the separating portion 51a without the partition portion 51b.

  The separating portion 51a is provided so as to be positioned on the opposite side of the guide member 41 with the flow of dust-containing air from the airflow inlet 14 toward the inner surface of the case lid 24 in a state where the case lid 24 is closed. Yes. Separation part 51a has the 1st filtration part 53-the 3rd filtration part 55 arranged in the width direction. The 1st filtration part 53 and the 2nd filtration part 54 are provided in the width direction both ends side part of the separation part 51a, and the 3rd filtration part 55 is provided in the width direction center part of the separation part 51a.

  The first filtration unit 53 to the third filtration unit 55 are formed by covering the openings opened in the respective parts with a net filter attached to the separation unit 51a. The size of the opening of the net filter is the same as that of the net filter 41b in order to obtain fine dust capturing performance as a more preferable example. However, the opening size of the net filter may be coarser than the size of the opening of the net filter 41b. In addition, the 1st filtration part 53-the 3rd filtration part 55 can be formed in the site | part in which many small holes or many slits were opened, without using a net filter, and if needed, coarse dust Any configuration can be used as long as the configuration can be captured.

  In order to support the dust separation member 51, support members 57 are attached to the inside of the case lid 24 and to both ends in the width direction. The support member 57 includes a support portion 57 a located near the pivot support means and a stopper portion 57 b located near the free end of the case lid 24. The support portion 57a and the stopper portion 57b have, for example, a rod shape, and protrude so as to be away from the inner surface of the case lid 24.

  The dust separating member 51 is rotatably attached to the support portion 57a via a pivot 58 (see FIGS. 6 to 8). For example, in FIG. 7, the pivot 58 connects the rear end portion of the partition portion 51b and the upper end portion of the support portion 57a. The separation part 51a, which is a part on the free end side of the dust separation member 51, can be brought into and out of contact with the upper end part of the stopper part 57b. 42b side).

  Therefore, the dust separation member 51 forms a dust storage space G (see FIG. 4) between the free end side portion (front portion) of the case lid 24 and the case lid 24 rotates around the pivot 58 as a fulcrum. It is provided so that the size of the outlet g (see FIG. 6) of the dust storage space G can be increased or decreased as it is moved. The outlet g of the dust storage space G is, for example, formed in an arc shape so as to be able to follow the inner surface of the case body 12, and is formed in a fully opened state without a partition or the like in the middle. Has been.

  As shown in FIG. 4, the dust separation member 51 is disposed in the dust chamber 42 of the case body 12 with the edge 51 c close to the inner surface of the case body 12 with the case lid 24 closed. Thereby, the dust storage chamber 42 is partitioned into a first chamber portion 42 a above the dust separation member 51 and a second chamber portion 42 b below the dust separation member 51. The air flow inlet 14 faces the first chamber portion 42a. The second chamber portion 42 b faces the inner surface of the case lid 24. Further, the first chamber portion 42 a and the second chamber portion 42 b are communicated with each other through a ventilation portion 52.

  A positioning portion 59 (see FIGS. 4 and 5) is provided on the inner surface of the case body 12. As the case lid 24 is opened and closed, the edge of the dust separating member 51 can be brought into contact with and separated from the positioning portion 59 from the lower side, and the positioning portion 59 removes the edge of the dust separating member 51 from the lower side. The first chamber 42a is supported from the side, that is, from the upper side. Providing the positioning portion 59 corresponding to the shape of the edge of the dust separation member 51 is preferable in that the gap between the inner surface of the case body 12 and the edge 51c of the dust separation member 51 can be closed.

  The filter 61 is formed by mounting a pleated filter member 63 as a filter element on a filter frame 62 as shown in FIG. 3, for example. The filter 61 is detachably fitted to the airflow outlet 18 of the case body 12 and attached to the dust collecting case 11.

  As shown in FIG. 1, the dust suction air passage member 71 includes a flexible dust suction hose 72, an extension pipe 73, and a suction port body 74.

  One end 72a of the dust suction hose 72 is detachably inserted into and connected to the hose connection port 4a of the cleaner body 2. By this connection, the air flow inlet 14 of the dust collection case 11 set in the dust collector housing chamber 3b and the inside of the dust suction hose 72 are communicated with each other. A hand handle 75 for moving and operating the suction port body 74 via the extension pipe 73 is provided at the other end (tip part) 72b of the dust suction hose 72 to which the extension pipe 73 is detachably fitted and connected. ing. A hand switch 76 for instructing operation of the electric blower 7 or the like is attached to the hand handle 75.

  The extension pipe 73 is formed by, for example, combining an outer pipe 73a and an inner pipe 73b so as to be extendable and contractible. The outer tube 73 a is detachably fitted to the other end 72 b of the dust suction hose 72. The connection pipe 74a of the suction port body 74 is detachably fitted to the tip of the inner pipe 73b protruding from the other end (tip) of the outer pipe 73a.

  As the electric blower 7 is operated in the state of FIG. 1, the dust-containing air sucked through a suction opening (not shown) opened on the lower surface of the suction port body 74 is drawn into the suction port body 74 and the extension pipe. 73, the dust suction hose 72 is passed through the air flow inlet 14 through the dust collection chamber 11 of the dust collection case 11 that passes through the dust suction hose 72 in the order of description and is set in the cleaner body 2. The dust-containing air sucked in this way is blown obliquely downward with respect to the upper portion of the guide member 41 and the central portion in the width direction, and is further guided by the guide member 41 toward the inner surface of the lower case lid 24.

  By the way, since the entire guide member 41 has air permeability, a portion for guiding the dust-containing air blown to the guide member 41 through the airflow inlet 14 toward the case lid 24, that is, in this embodiment, the guide. The central portion of the member 41 in the width direction also has air permeability. Therefore, a part of the air guided by the guide member 41 passes through the guide member 41 toward the filter 61 attached to the airflow outlet 18. Accordingly, even if dust is filtered and captured on the front surface of the guide member 41, it is blown off by the momentum of the airflow toward the inner surface of the case lid 24. Therefore, a reduction in the amount of air sucked into the electric blower 7 can be suppressed so that the suction work rate of the electric blower 7 does not decrease.

  The dust-containing air guided by the guide member 41 is smoothly changed in the flow direction to the front side by the first air guide portion 24c of the case lid 24, and is further positioned on the front side from the first air guide portion 24c. The flow direction can be smoothly changed upward by the second air guiding portion 24d of the case lid 24. That is, the dust-containing air that is guided by the guide member 41 and reaches the inner surface of the case lid 24 is reversed on the inner surface of the case lid 24 toward the separation portion 51 a of the dust separation member 51. Such a flow of airflow is indicated by a solid line arrow in FIG.

  Dust (mainly coarse dust) in the dust-containing air inverted upward is filtered by the first filtration unit 53 to the third filtration unit 55 of the dust separation member 51 and captured by these. On the other hand, the air and fine dust separated from the trapped dust pass through the first filtration unit 53 to the third filtration unit 55, and further, through the first chamber unit 42a, the air flow outlet. 18 passes through the net filter 41 b of the guide member 41 toward the filter 61 attached to 18. Such an air flow is indicated by a dotted arrow in FIG. The dotted line arrow and the solid line arrow indicate the path of the dust chamber indoor airflow that flows in from the airflow inlet 14, reverses at the inner surface of the case lid 24, passes through the dust separation member 51, and flows toward the airflow outlet 18.

  In this case, the air that has passed through the first filtration part 53 and the second filtration part 54 circulates toward both sides of the width direction of the guide member 41 having air permeability toward the filter 61. The third filtration unit 55 provided at the central portion of the separation unit 51 a is located on the front side of the flow of dust-containing air that flows downward along the guide member 41. Therefore, the air that has passed through the third filtration unit 55 bypasses the dust-containing airflow that flows downward toward the case lid 24 to the left and right, and then circulates toward the filter 61 on both sides in the width direction of the guide member 41. .

  Since the dust separated from the air flow in the dust storage chamber by the filtration by the dust separation member 51 described above is sucked to the lower side of the separation portion 51a, the separation portion 51a and the case lid are increased as the amount thereof increases. The dust is gradually compressed while being stored in the space G so as to store the dust between the front part of 24.

  In the dust collection into the dust collection case 11 described above, since the dust separation member 51 partitions the first chamber portion 42a and the second chamber portion 42b, the dust chamber airflow does not pass through the separation portion 51a. Further, it is difficult to pass from the second chamber portion 42b to the first chamber portion 42a. Moreover, the first chamber portion 42a side (upper side) is formed between the inner surface of the case body 12 and the edge 51a of the dust separation member 51 by the positioning portion 59 provided corresponding to the shape of the edge 51a of the dust separation member 51. It is blocked from. Therefore, also in this respect, the dust chamber airflow hardly passes through the first chamber portion 42a from the second chamber portion 42b without passing through the separation portion 51a. Therefore, dust and air can be reliably separated by the separation portion 51a of the dust separation member 51.

  Further, in the dust collection, the rotatable dust separation member 51 receives an upward force due to wind pressure and compression of the collected dust. The dust separation member 51 is positioned by the positioning portion 59. Therefore, the dust separation member 51 may be carelessly rotated upward so that the dust chamber airflow can easily pass from the lower second chamber portion 42b to the upper first chamber portion 42a. Absent. Thereby, dust-containing air can be reliably circulated to the separation part 51a and filtered and separated. Therefore, coarse dust does not adhere to the net filter 41b of the guide member 41, and a strong suction force can be maintained.

  Further, fine dust in the air that has passed through the guide member 41 is captured by the filter member 63 of the filter 61. And the air which passed the filter member 63 is suck | inhaled by the electric blower 7, and the air discharged | emitted from this electric blower 7 is discharge | released outside the cleaner body 2. FIG.

  Next, the dust disposal procedure will be described.

  First, as shown in FIG. 2, the dust collector case 11 is taken out of the dust collector housing chamber 3 b of the cleaner body 2 while holding the handle 19 with the cleaner body cover 4 opened.

  Thereafter, after transporting the dust collecting case 11 to the dust disposal site, the operation lever 34 of the clamp mechanism 31 is operated to remove the hook portion 32 a of the clamp lever 32 from the locking claw portion 28 of the case lid 24. Thereby, the case lid 24 is rotated downward by its own weight with the pivot 25 as a fulcrum, and the dust outlet 16 of the case body 12 is opened.

  Along with the opening operation of the case lid 24, dust accumulated between the inner surface on the free end side of the case lid 24 and the separation portion 51 a of the dust separation member 51 passes through the dust outlet 16 and below the case body 12. Pulled out. In order to move the dust collected in this way to the outside of the case body 12, it is only necessary to open the case lid 24.

  Such opening of the case lid 24 is not energized by being energized. At the same time as the free end of the case lid 24 faces directly below, a light impact is applied to the case lid 24 as the opening angle of the case lid 24 is restricted. Thereby, the dust accumulated between the case lid 24 and the dust separation member 51 falls through the outlet g of the dust storage space G between the case lid 24 and the dust separation member 51, and the lower dust It is discharged into a receiving container.

  In this case, as described above, since the dust is not discharged at a stretch under a large impact, the discharged dust is difficult to fly up and fly up. Therefore, after dust disposal, cleaning around the dust disposal site is not indispensable, and the effort can be reduced even when cleaning.

  Moreover, since the dust separating member 51 is rotatable, when the case lid 24 is opened and the edge of the dust separating member 51 moves away from the positioning portion 59, the dust is collected and the dust in the compressed state expands, so that the dust separation is performed. The member 51 is rotated about the pivot 58 as a fulcrum. As a result, the separating portion 51a is further separated from the inner surface of the case lid 24, and the outlet g of the dust storage space G is further opened, so that the collected dust is drawn out of the case main body 12 and moved downward. This dust can be easily dropped as it faces.

  FIG. 10 shows a second embodiment of the present invention. The configuration of the second embodiment is the same as that of the first embodiment, except for the configuration described below, including the configuration not shown in FIG. Therefore, the same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

  In 2nd Embodiment, it replaced with the 3rd filtration part in the separation part 51a of the dust separation member 51 demonstrated in 1st Embodiment, and provided the wind-shielding part 51d. This wind shield 51d is provided so as to occupy the central part in the width direction of the separating part 51a of the dust separating member 51, and the first filtering part 53 is provided on the left and right sides thereof, that is, on both ends in the width direction of the dust separating member 51. And the 2nd filtration part 54 is provided.

  Furthermore, in the second embodiment, the partition plate 56 protruding into the first chamber portion 42a (see FIG. 4 and the like) with the case lid 24 closed is provided at the edge of the ventilation portion 52 of the dust separation member 51. It is provided along. In the second embodiment, the partition plate 56 is divided into two sheets, but it is also possible to form a single continuous partition plate. The rear end of the partition plate 56 is in contact with or close to the front surface of the guide member 41 (see FIG. 4 etc.), and the partition plate 56 is provided so that its upper end is close to the air flow inlet 14 (see FIG. 4 etc.). It is preferable.

  The configuration other than these points is the same as that of the first embodiment. Therefore, also in the second embodiment, the problem of the present invention can be solved for the reason already described in the first embodiment, and when discharging dust from the dust collection case, the discharged dust is less likely to fly up and fly up. Can provide a machine.

  In addition, the first filtration part 53 and the second filtration part 54 and the downward airflow guided by the guide member toward the case lid 24 through the airflow inlet 14 are collected in a state where the case lid 24 is closed. When the case 11 is viewed from the front to the rear, the dust collection case 11 is displaced in the width direction. Therefore, interference between the downward airflow and the airflow flowing into the filter 61 (see FIG. 3) through the first filtration unit 53 and the second filtration unit 54 can be suppressed. In addition, this interference can be further suppressed by the partition plate 56. Therefore, since it is difficult for turbulent flow to occur in the dust storage room airflow, there is an advantage that it is possible to suppress a reduction in the suction work rate of the electric blower.

  The present invention is not limited to the above embodiments. For example, an upper portion in the center portion in the width direction of the guide member 41 to which the dust-containing airflow that has passed through the airflow inlet 14 blows, and a lower portion in the center portion in the width direction of the guide member 41 that guides the dust-containing airflow to the inner surface of the case lid 24 from here. It does not have to be breathable. That is, the central portion in the width direction of the guide member 41 may not have air permeability.

  Furthermore, it is also possible to employ a configuration in which an air guide pipe is provided in the case body so as to penetrate the guide member, and the air that has passed through the separation portion of the dust separation member is guided to the filter by this pipe. In this case, the guide member may not have air permeability.
