The vacuum cleaner body 1 is mounted in an inclined state so as to be positioned in front of the cleaner body 1.

  FIG. 3 is an exploded perspective view showing the cyclone dust collector.

  The dust separation unit 20 of the cyclone dust collecting apparatus 10 has an outer cylinder 21 having a substantially cylindrical shape, and an inlet pipe connected to a hose attachment port 12 (see FIG. 1) on the lower surface in the axial direction of the outer cylinder 21. 22 is formed.

In addition, a circular opening 27 is formed substantially at the center of the upper surface 20a of the dust separation part 20, and a sealing member 27s having a cylindrical shape and increasing in diameter upward is provided at an edge of the opening 27.
Further, on the upper surface 20 a, a wide communication path 26 is opened in front of the opening 27, and a cylindrical seal member 26 s is provided at an edge of the communication path 26. The opening 27 and the communication path 26 communicate with the inlet pipe 22.

  Further, a pair of guide portions 20b and 20b are formed on the upper surface 20a of the dust separation portion 20 so as to protrude. In addition, a guide portion 20c is formed on the upper surface 20a. Details of the guide portion 20b will be described later (see FIG. 13).

  The dust container 30 of the cyclone dust collector 10 has a substantially cylindrical shape, and a lid 50 is provided in front of the dust collection case 40. Further, the dust container 30 includes an upper cover 60 including a handle 61 and a release button 62 on the dust collection case 40 and the lid 50. The peripheral surface of the upper cover 60 has a flat shape along the left side surface 40c (see FIG. 2), the right side surface 40d and the outer surface of the lid 50 of the dust collecting case 40, and the front side is lower than the rear side in the front-rear direction. It is inclined to.

  FIG. 4 is a plan view showing the dust container.

  FIG. 5 is a perspective view showing the dust container when the lid is opened.

  The dust collection case 40 has an opening 40 s having a substantially rectangular shape at the front. Note that the surface including the opening formed by the opening 40s corresponds to the opening surface M1. Incidentally, if the dust collecting case 40 is the opening surface M1 parallel to the axial direction of the dust collecting case 40, the vacuum cleaner 100 is made to be an opening surface cut in a direction orthogonal to the axial direction of the dust collecting case 40. This is because when the dust container 30 is downsized in order to reduce the size, it is impossible to secure a large opening area of the opening surface.

  The dust collection case 40 includes a dust collection basket 41 and a dust collection filter 43 (see FIG. 6).

  The dust collecting basket 41 has a substantially trapezoidal shape in a cross-sectional view (side view), and an upper container (support frame) 41a and a lower container (support frame) 41b which are divided into upper and lower parts are hinges 41c at the rear (see FIG. 6). When the trash is thrown away, the upper container 41a and the lower container 41b are opened in the vertical direction by a hinge 41c (see FIG. 6), and the shaft 41d (only one shown) is provided at the lower end of the lower container 41b. As a rotation. The shaft 41d is rotatably supported on the inner wall surfaces of the left and right side surfaces 40c, 40d (see FIG. 2) of the dust collection case 40. In addition, the dust collecting basket 41 should just have a concave surface facing the opening part 40s side, and a shape other than that is not specifically limited.

  The cross-sectional shape of the dust collecting basket 41 in the front-rear direction may be a substantially square shape, a substantially circular shape, or a substantially triangular shape. Preferably, it is formed so that a cross section becomes smaller from the opening side (front side) toward the bottom side (rear side). By forming in this way, the cross-sectional area increases toward the side (opening side) where the dust is discharged, so that the user can easily discharge the dust accumulated in the dust collecting basket 41.

  The dust collecting basket 41 has a frame body 41e (support frame), and a mesh member 41f (partially shown) made of metal, nylon, or the like is covered and pasted on the bottom surface, upper, lower, left and right surfaces excluding the opening. It is configured by wearing or insert molding. Thus, by providing air permeability not only on the bottom surface of the dust collecting basket 41 but also on the top, bottom, left and right surfaces, a flow path can be secured even if dust accumulates on the bottom surface of the dust collecting basket 41. Thereby, the pressure loss of suction | inhalation air can be reduced and the fall of a suction force can be suppressed.

  The lid 50 opens and closes the opening 40s (opening surface M1) on the front side of the dust collecting case 40, and is formed in the lid 50 so that the concave surfaces face each other with respect to the dust collecting basket 41. A recess 52 is formed. The opening area of the opening 52 a of the recess 52 is formed to be substantially the same as the opening area of the dust collecting basket 41.

  A flat check valve 53 made of an elastic material is provided on the inclined surface (bottom surface) 52 a 1 of the recess 52.

  Further, the lower part of the lid part 50 is rotatably connected to the lower part of the dust collecting case 40 via a hinge part 54. Thereby, the cover part 50 is comprised so that it may rotate below with respect to the opening surface M1 of the dust collection case 40 in the direction away from the opening surface M1.

  FIG. 6 is a longitudinal sectional view when the cyclone dust collector is mounted on the cleaner body.

  As shown in FIG. 6, the cyclone dust collecting device 10 is mounted on the front portion of the cleaner body 1 such that the upper portion is in a rearward inclined posture located rearward of the lower portion. The cyclone dust collector 10 is arranged so that its axial direction is inclined with respect to the vertical direction. Thereby, the vacuum cleaner main body 1 including the cyclone dust collector 10 can be made smaller than the case where the axial direction of the cyclone dust collector is configured. Further, the dust container 30 of the cyclone dust collector 10 has a back surface supported by the cleaner body 1 and a bottom surface supported by the dust separator 20. That is, a member that supports the dust container 30 from the front to the outer peripheral surface of the side surface is not provided.

  The dust collecting case 40 is formed in a substantially rectangular tube shape having an upper surface 40a, a bottom surface 40b, a left side surface 40c (see FIG. 2) and a right side surface 40d (see FIG. 3), and has a front side (front side) and a rear side (rear side). ) Have openings 40s and 40f that open respectively.

  The dust collecting basket 41 is rotatably connected to a support portion 42 provided at the front portion on the bottom side of the dust collecting case 40. The support portion 42 is provided with a torsion coil spring 42a (see FIG. 11), and is configured such that the dust collection basket 41 jumps out to the front of the dust collection case 40 by the urging force of the torsion coil spring 42a (see FIG. 11). (See FIG. 5). At this time, the dust collected in the dust collection basket 41 can be discharged to, for example, a trash box by the momentum of the dust collection basket 41 jumping out from the dust collection case 40.

  The mesh member 41f is air permeable and has a filter function of collecting dust. In addition, as long as it has a filter function which collects dust, a disposable tissue paper may be used instead of the mesh member 41f, or the mesh member 41f and the tissue paper may be combined. By using tissue paper on the mesh member 41f, it is easy to dispose of the dust in the dust collecting basket 41.

  As shown in FIG. 6, the lid 50 is formed with a communication path 51 that is connected to the recess 52 and extends downward. The communication path 51 extends toward the lower dust separator 20 and is connected to an opening 50a1 formed in the bottom surface 50a. The communication path 51 extends substantially in parallel to the opening 40s (opening surface M1) of the dust collecting case 40. However, the air flow is directed to the opening M1 by the recess 52 provided in the lid 50. It can be turned to. The recess 52 is provided to rectify the flow. The recess 52 may have a trapezoidal cross section as shown in the figure, or the upper portion of the recess 52 can be rectified by making an arc shape in cross section. That is, the recess 52 has a cross-sectional shape that expands toward the opening surface M1 of the dust collecting basket 41.

  Thus, the opening surface M1 of the dust collecting case 40 is configured to be substantially parallel to the dust introduction direction (dust introduction direction) of the communication path 51.

  The check valve 53 is provided on a surface of the recess 52 to which the communication path 51 is connected, and allows only a flow from the communication path 51 side to the recess 52 side. Incidentally, the check valve 53 is attached to an inclined surface 52a1 which is a surface (lower surface) communicating with the communication path 51 of the recess 52. When the recess 52 is formed in a trapezoidal cross section in this way, the outlet of the communication path 51 is provided. The opening area of the outlet can be increased as compared with the case where the check valve 53 is leveled, and a fixing portion for fixing the check valve 53 to the recess 52 can be sufficiently secured.

  Further, the fixing portion for fixing the check valve 53 may be provided on the dust collecting basket 41 side. Thereby, when the operation of the vacuum cleaner 100 (see FIG. 1) is finished, it is possible to prevent heavy fine dust such as sand from falling on the dust separation unit 20.

  Further, a hook-like engaged projection 56 that engages with a lock member 66 described later is formed on the upper surface 50 b of the lid 50.

  The front surface of the lid 50 is made of a transparent resin or the like so that dust accumulated in the dust collecting basket 41 can be confirmed with the lid 50 closed.

  The dust separator 20 has an outer cylinder 21 having a substantially cylindrical shape, and an inlet pipe 22 connected to the hose attachment port 12 (see FIG. 1) is formed on the lower surface of the outer cylinder 21 in the axial direction. ing.

  In the outer cylinder 21, an introduction part 23 that communicates with the inlet pipe 22, an inner cylinder 24 that communicates with the dust collection case 40 of the dust container 30, and the introduction part 23 and the inner cylinder 24 communicate with each other, and the hose attachment port 12. A turning circuit 25 is provided for turning air flowing into the cleaner main body 1 and dust sucked together with the air. The inner cylinder 24 has a plurality of through holes 24a. Further, on the outer peripheral side of the outer cylinder 21, a communication path 26 that connects the turning circuit 25 and the lid portion 50 (communication path 51) is formed.

  Note that a mesh member made of metal, nylon, polyester, or the like may be attached to the through hole 24a of the inner cylinder 24 by coating or insert molding. Moreover, you may comprise with the metal (for example, stainless steel) containing or apply | coated the antibacterial metal (for example, silver) and the antibacterial substance (for example, silver) so that propagation of a microbe can be suppressed.

The introduction portion 23 has a concave shape and is disposed such that the concave surface faces the inlet pipe 22.
Therefore, the air containing dust or the like introduced from the inlet pipe 22 collides with the bottom surface of the concave surface, then flows along the side surface of the concave surface, and flows into the turning circuit 25.

  The inner cylinder 24 is formed at the center in the radial direction of the outer cylinder 21 and is located on the back side of the introduction portion 23. Light dust passes through the through hole 24 a formed in the inner cylinder 24. The downstream end of the inner cylinder 24 communicates with an opening 40 t formed in the bottom surface 40 b of the dust collection case 40.

  The turning circuit 25 is formed outside the introduction portion 23 and the inner cylinder 24 and has a function of separating air and dust by centrifugal force.

  The communication path 26 is configured such that the upstream end communicates with the turning circuit 25 and the downstream end communicates with a communication path 51 formed in the lid portion 50. The cyclone dust collecting apparatus 10 is provided with seal members 26s, 51s, and 27s so as to ensure airtightness. That is, as shown in FIG. 6, the seal member 26s is a seal member (packing) for ensuring airtightness between the communication path 26 and the opening 50a1, and the seal member 51s includes the communication path 51 and the lid portion. 50 is a seal member (packing) for ensuring airtightness between the two, and the seal member 27s is a seal member (packing) for securing airtightness of the opening 40t. Further, the sealing member 26s is provided in order to ensure airtightness in the dust accommodating portion 30, and the sealing members 51s and 27s ensure airtightness between the dust separating portion 20 and the dust accommodating portion 30. Is provided to do.

  In the cyclone dust collecting apparatus 10 configured as described above, when the air that has flowed into the cleaner body 1 from the hose attachment port 12 and the dust sucked together with the air are introduced from the inlet pipe 22 into the introduction portion 23, the introduction is performed. It collides with the front wall surface in the section 23 and is introduced toward the turning circuit 25 to turn the turning circuit 25. Air and dust are separated by the centrifugal separation effect of this swirl. Due to the centrifugal separation action, a large amount of dust is contained in the air on the outer peripheral side, and conversely, the air is reduced in the air on the inner peripheral side.

  The dust collection case 40 is provided with a dust collection filter 43 that can be opened and closed (rotatable) about a hinge 44 (see FIG. 5). The dust collection filter 43 is configured so that the rear surface of the dust collection filter 43 comes into contact with an intake duct (not shown) of the cleaner body 1 in a state where the dust collection filter 43 is attached to the opening 40 f of the dust collection case 40.

  The dust collection filter 43 is folded in a pleat shape, and for example, a high-density HEPA filter (High Efficiency Particulate Air Filter) can be used. The HEPA filter has a particle collection rate of 99.97% or more with respect to particles having a rated air volume and a particle size of 0.3 μm, and an initial pressure loss of 245 Pa or less.

  The fold line direction of the mountain fold of the dust collection filter 43 is preferably the vertical direction (gravity acting direction). This is a case where a dust removal mechanism for removing dust accumulated on the dust collection filter 43 by applying an impact to the dust collection filter 43 is provided downstream of the dust collection filter 43 (on the cleaner body 1 side). This is because if the folding direction is the vertical direction, fine dust adhering to the dust collection filter 43 is easily dropped and removed. The fold line direction of the mountain fold may be arranged obliquely.

  As shown by solid line thick arrows in FIG. 6, the air containing a large amount of dust after centrifugation passes through the communication paths 26 and 51 in the opening direction of the dust collecting basket 41 along the shape of the recess 52 of the lid 50. The direction is changed and dust accumulates in the dust collecting basket 41. The air that has passed through the dust collecting basket 41 is sucked into an electric blower (not shown).

  In addition, as shown by the thick broken line arrows in FIG. 6, the light dust that cannot be separated by the centrifugal separation action of the dust separation portion 20 and has passed through the through hole 24a of the inner cylinder 24 passes through the openings 27 and 40t. 40 enters and is collected by the dust collection filter 43. The air that has passed through the dust collection filter 43 is sucked into an electric blower (not shown).

The bearing portion 45b is notched in a U shape so that the upper end is open, and a shaft portion 66c of a lock member 66 described later is pivotally supported. Further, a guide projection 46 that supports one end (lower end) of a compression coil spring 67, which will be described later, projects from the frame body 45.

  The lock member 66 has a base portion 66a formed by projecting shaft portions 66c and 66c on both left and right end faces, and a hook-like claw portion 66b integrally formed forward from the base portion 66a. A circular protrusion 66d is formed on the upper surface of the base 66a, and a guide protrusion 66e that supports the compression coil spring 67 is formed on the lower surface of the base 66a.

  Further, the lock member 66 is accommodated in the frame body 45, and the shaft portions 66c and 66c are supported by the bearing portions 45b and 45b, so that the lock member 66 is supported by the seesaw around the rotation shaft S2. It is configured.

  A through hole 40a1 (see FIG. 10A) for moving the claw 66b back and forth toward the lid 50 is formed on the upper surface 40a in the frame 45. Moreover, the rear part of the upper surface 40a has a bulging part 40a2 protruding upward, and the upper end part of the dust collection filter 43 is accommodated inside the bulging part 40a2 (see FIG. 6). Further, on the upper portion of the dust collection filter 43, latching portions 70 and 70 for latching the dust collection case 40 and the dust collection filter 43 are provided. The illustration of the latching state between the latching portion 70 and the dust collecting filter 43 is omitted. The retaining portion 70 has a shape for fixing the dust collecting filter 43 to the dust collecting case 40, and the dust collecting filter 43 attached to the hinge portion 44 (see FIG. 5) so as to be rotatable is disposed on the retaining portion 70, It is fixed at 70.

  When the handle 61 is not operated, the engaging portion 64a of the engaging protrusion 64 protrudes rearward from the rear end surface of the upper cover 60 by the urging force of the compression coil spring 65 (see FIG. 4). Thereby, the dust accommodating part 30 is supported by the cleaner main body 1 by the engaging part 64a being latched by the engagement hole 1a (refer FIG. 6) provided in the cleaner main body 1 side.

  Next, each operation of the dust container 30 will be described with reference to FIGS. 10A is a cross-sectional view taken along the line BB in FIG. 4, FIG. 10B is a cross-sectional view taken along the line CC in FIG. 4, and FIG. 11 shows the dust container when the lid is opened. 12 is a cross-sectional view when cut at a position corresponding to the line BB, and FIG. 12 is a cross-sectional view when the dust container is cut at a position corresponding to the line CC in FIG. 4 when the lid is opened. .

  First, the state of the dust container 30 before operating the handle 61 will be described.

  As shown in FIG. 10A, when the dust container 30 is mounted on the cleaner body 1 (see FIGS. 1 and 6) (not shown) and the handle 61 is not operated, the dust collecting case 40 is used. The opening surface M <b> 1 is closed by the lid portion 50.

  At this time, since the release button 62 is not pushed down, the lock member 66 is rotated counterclockwise by the urging force of the compression coil spring 67 about the shaft portion 66c (the rotation shaft S2, see FIG. 9). The claw portion 66b of the lock member 66 protrudes downward from the through hole 40a1 and engages with the engaged protrusion 56. Thereby, the lid 50 is locked so as not to be opened, and the opening surface M1 is closed.

  The engaging portion 64 a of the engaging protrusion 64 is biased by the biasing force of the compression coil spring 65 and protrudes rearward from the through hole 60 g of the rear surface 60 a 2 of the upper cover 60. The engaging portion 64a protrudes in this way because the pressed portion 64b of the engaging protrusion 64 is separated from the pressing protrusion 61e formed on the handle 61, as shown in FIG. This is because the engagement protrusion 64 is moved rearward by the biasing force of the compression coil spring 65.

  Note that, in a state where the opening surface M1 is closed by the lid 50, the center of gravity G of the dust container 30 is at the position shown in FIG. That is, the center of gravity G of the dust container 30 is configured to be located between the front plate portion 61 a that is the handle portion of the handle 61 and the rotation axis S <b> 1 of the handle 61.

  As shown in FIG. 11, in a state where the front plate portion (handle portion) 61a of the handle 61 is gripped (a state where a finger is put on the front plate portion 61a), the dust collecting case 40 has the rotation shaft S1 as a fulcrum. It rotates counterclockwise and operates so that the rotation axis S1 and the center of gravity G of the dust container 30 are positioned on the vertical direction Sa. Thereby, the line Sb of the opening surface M1 of the dust collecting case 40 is directed downward (inclined forward) with respect to the vertical direction Sa. In addition, in FIG. 11, the state which opened the cover part 50 is also shown in figure, However, Even when the cover part 50 is closed, line Sb of the opening surface M1 of the dust collecting case 40 is similarly vertical direction Sa. It will face down.

Further, by depressing the release button 62, the engaged state of the engaged protrusion 56 of the lid 50 and the claw 66b of the lock member 66 is released, and the lid 50 rotates counterclockwise with the hinge 54 as a fulcrum. Rotate in the direction, and the opening surface M1 of the dust collecting case 40 is opened. At this time, the dust collecting basket 41 in the dust collecting case 40 is rotated from the opening surface M1 while rotating about the lower end shaft 41d (see FIG. 5) by the biasing force of the torsion coil spring 42a. A part of protrudes.
Further, when the dust collection basket 41 protrudes, the upper container 41a and the lower container 41b are vertically broken.

  Thereby, the line Sc of the open surface M2 (see FIG. 11) of the upper container 41a of the dust collecting basket 41 is further downward (inclined forward) than the line Sb of the opening surface M1.

  Further, from the state shown in FIG. 10, the handle portion (front plate portion 61 a) of the handle 61 of the dust container 30 is rotated with respect to the upper cover 60 using the rotation shaft S <b> 1 (shaft portion 61 d) as a fulcrum. When pulled up, the dust container 30 can be removed from the cleaner body 1.

  That is, as shown in FIG. 12, when removing the dust container 30 from the cleaner body 1 (see FIG. 1), if the handle 61 is lifted upward with respect to the upper cover 60, the handle 61 is moved to the rotation axis S1 (FIG. 11), the rear plate portion 61b of the handle 61 enters the first recess 60a, and the upper plate 61b1 is inclined. At this time, the pressing projection 61e formed on the lower surface of the upper plate 61b1 simultaneously rotates downward, and the pressing projection 61e contacts the tapered surface 64b1 of the pressed portion 64b of the engaging projection 64. Then, the pressing protrusion 61e rotates further downward so that the pressing protrusion 61e slides on the tapered surface 64b1 of the pressed part 64b, and the pressed part 64b is compressed by the pressing force of the pressed part 64b. Slide forward while resisting the urging force of 65. In this manner, the engaging portion 64a slides forward, whereby the engaging portion 64a is retracted into the upper cover 60. Therefore, the engagement state between the dust container 30 and the cleaner body 1 is released, and the dust container 30 can be detached from the cleaner body 1.

  Further, when the handle 61 is pulled up, the flange 61a3 of the handle 61 is hooked on the opening edge of the first recess 60a (see FIG. 12), so that the rotation of the handle 61 is restricted. Has been.

  As shown in FIGS. 11 and 12, when the release button 62 is pushed down against the urging force of the compression coil spring 63 (see FIG. 7), the lock release pin 62c (see FIG. 12) is inserted into the through hole 60p (see FIG. 12). 8), the tip of the lock release pin 62c (lower end) presses the upper surface of the base 66a of the lock member 66. As a result, the lock member 66 rotates clockwise (see FIG. 12) about the rotation shaft S2 (see FIG. 9) while resisting the urging force of the compression coil spring 67 (see FIG. 10). Accordingly, the claw portion 66b is lifted and stored in the through hole 40a1, so that the engagement with the engaged protrusion 56 (see FIG. 11) of the lid portion 50 is released. As a result, the lid 50 is opened by receiving the pushing force when the dust collecting basket 41 is pushed out of the dust collecting case 40 by the biasing force of the torsion coil spring 42a.

In such a vacuum cleaner 100, the dust container 30 includes a dust collection case 40, a movable handle 61, and an openable / closable lid 50 (lid), and the dust collection case 40 is closed by the lid 50. The opening M1 is substantially parallel to the dust introduction direction of the dust collection case 40, and the center of gravity of the dust container 30 when the dust collection case 40 is closed by the lid 50 is the front plate portion (the handle portion) of the handle 61. ) 61a and the rotation axis S1 of the handle 61 (see FIG. 10A).
According to this, when the front plate part (handle part) 61a of the handle 61 is hung by hand, the center of gravity G moves so as to be positioned in the vertical direction Sa, thereby opening the dust collecting case 40. The surface M1 can be made to face downward (bowing direction) with respect to the vertical direction Sa, and the processing when the dust in the dust collecting case 40 is discarded in the trash box placed on the floor surface is facilitated. That is, when the user holds the handle 61, the opening surface M1 is naturally downward with respect to the vertical direction Sa, so there is no need to intentionally direct the opening surface M1 of the dust collecting case 40 to the trash can, or The angle toward the trash can can be reduced.

Moreover, in the vacuum cleaner 100, when the dust accommodating part 30 is mounted | worn with the vacuum cleaner main body 1, the opening surface M1 is set upward with respect to the perpendicular direction (refer FIG. 1, FIG. 6), and the vacuum cleaner main body 1 The opening surface M1 is configured to face downward with respect to the vertical direction when removed from the vertical direction.
According to this, when the dust container 30 is mounted on the cleaner body 1, the dust collected in the dust collecting basket 41 passes through the recess 52 and the communication path 51 so that the dust container 30 is directed upward. Can be prevented from falling, and dust disposal is facilitated.

  Moreover, according to the vacuum cleaner 100, the dust collection basket 41 which opens toward the opening surface M1 is provided in the dust collection case 40, and when the opening surface M1 is opened, the opening surface M2 of the dust collection basket 41 is It can be set further downward with respect to the opening surface M1 of the dust collection case 40. According to this, since the open surface M2 (see FIG. 11) of the dust collection basket 41 can be made further downward than the opening plane M1 with respect to the vertical direction Sa, the dust in the dust collection basket 41 is discarded. The processing becomes even easier.

  In the vacuum cleaner 100, the dust container 30 has an engaging portion 64 a that engages with the cleaner body 1, and the engaging portion 64 a is engaged with the cleaner body 1 in conjunction with the operation of the handle 61. The combined state is released. According to this, the function of making the opening surface M1 of the dust collecting case 40 downward and the function of releasing the lock with the cleaner body 1 can be performed with one handle 61, the number of parts can be reduced, The internal operation mechanism can be simplified.

  FIG. 13 is a top view showing the dust separator.

  On the upper surface 20a of the dust separator 20, guide portions 20b and 20b formed in a substantially L shape in plan view are formed. The guide portions 20 b and 20 b are located between the communication path 26 and the opening 27 and at the rear of the left and right ends of the communication path 26. That is, the guide portions 20 b and 20 b are located in the vicinity of the communication path 26 and the opening 27.

  The guide part 20b has a standing part 20b1 extending in the front-rear direction and a standing part 20b2 extending outward from the front end of the standing part 20b1, and has a substantially L shape. Reinforcing ribs 20b3 and 20b4 are formed on the inner side surface of the upright portion 20b1 at intervals in the front-rear direction. In addition, knobs 20d and 20d for removing the dust separation part 20 from the cleaner body 1 are provided upright behind the guide parts 20b and 20b. In addition, the dust separation part 20 can be removed from the cleaner main body 1 by picking up the knob parts 20d and 20d by, for example, picking up one with a thumb and the other with a finger.

  FIG. 14 is a bottom view showing the dust container.

  The bottom plate 40b1 of the dust collection case 40 is formed in a substantially rectangular shape, and a circular opening 40t is formed through the center in the left-right direction and closer to the lid 50.

  The bottom plate 50c of the lid 50 is formed so as to protrude in a substantially mountain shape toward the front, and is formed with a communication path 51 having a shape that is slightly smaller than the bottom plate 50c and substantially along the outer periphery of the bottom plate 50c. That is, the lid 50 is not a simple thin plate-like planar shape but a three-dimensional shape having the bottom plate 50c.

  The lower surface 40b2 and 50c1 of the dust collection case 40 and the lid 50 are connected to each other via hinges 54 and 54. That is, the hinge portion 54 is provided on the arm portion 54a extending from the lower surface 50c1 of the lid portion 50 toward the lower surface 40b2 of the dust collection case 40 and the lower surface 40b2 of the dust collection case 40, and is provided at the tip of the arm portion 54a. And a bearing portion 54b that rotatably supports a shaft 54a1 (see FIG. 5).

  The hinge portion 54 has an arm portion 54a located outside the bearing portion 54b. Further, the base end portion of the arm portion 54 a is located at the rear end of the lower surface 50 c 1 of the lid portion 50. Further, the bearing portion 54 b is located at the front end of the lower surface 40 b 2 of the dust collection case 40.

  Returning to FIG. 13, when the dust container 30 is superimposed on the dust separator 20, the bearing 54 b of the hinge 54 contacts the guide 20 b as indicated by a two-dot chain line in FIG. 13. That is, the side surface of the bearing portion 54b contacts the upright portion 20b1 of the guide portion 20b, and the front end of the bearing portion 54b contacts the upright portion 20b2 of the guide portion 20b.

  As described above, in the vacuum cleaner 100, the hinge portions 54 and 54 are positioned by the guide portions 20b and 20b, so that the dust storage portion 30 moves forward and left and right relative to the dust separation portion 20, and is twisted. The movement in the direction (clockwise direction or counterclockwise direction in FIG. 13) can be restricted. Note that the rearward movement of the dust container 30 can be naturally regulated by attaching the back surface of the dust separator 20 to the cleaner body 1 (see FIG. 6).

  Therefore, the airtightness at the boundary between the opening 27 (see FIG. 13) of the dust separator 20 and the opening 40t (see FIG. 14) of the dust container 30 and the communication path 26 (see FIG. 13) of the dust separator 20 It can reduce that the airtightness in the boundary with the communication path 51 (refer FIG. 14) of the dust accommodating part 30 is impaired.

  Further, in the vacuum cleaner 100, the hinge portion 54 is positioned by the guide portion 20b in the vicinity of (closest to) the communication path 26 (51) and the opening 27 (40t) that require airtightness. It is possible to suppress the positional deviation between the openings 26 and 51 and between the openings 27 and 40t, and to reduce the leakage from the boundary portion.

  Moreover, in the vacuum cleaner 100, since the dust accommodating part 30 can be positioned in the dust separation part 20 using the hinge part 54, it becomes unnecessary to provide the member for positioning separately from a hinge part, and a number of parts Can be reduced.

  Moreover, in the vacuum cleaner 100, since the hinge part 54 is arrange | positioned in the lower surface (dust separation part 20 side) of the dust accommodating part 30, when the dust accommodating part 30 is mounted | worn with the cleaner main body 1, a hinge part 54 or a guide The unevenness due to the portion 20b can be hidden at a position where it cannot be visually recognized, and the dust container 30 can be easily handled without being caught by the uneven portion.

FIGS. 15A and 15B show a procedure when a tissue is attached to a dust collecting basket. FIG. 15A shows a state before the lid is closed, and FIG. 15B shows a state after the lid is closed. 15A and 15B exaggerate the thickness of the tissue T so that the state of the tissue T can be easily understood.
By using the vacuum cleaner 100 with the tissue T attached to the dust collecting basket 41, when the garbage (dust) collected in the dust collecting basket 41 is disposed of in a trash box or the like, the dust in the dust collecting basket 41 (dust) ) Can be easily discharged.

  As shown in FIG. 15A, as a procedure for attaching a tissue T (commercially available box tissue or the like) to the dust collecting basket 41, first, the lid 50 of the dust container 30 is opened, and the dust collecting case 40 is opened. Is placed on the floor surface 200 or the like with the back side facing downward. Thereby, since the opening of the dust collecting basket 41 faces upward, the tissue T can be easily attached. When the lid 50 is opened, a part of the dust collecting basket 41 protrudes from the dust collecting case 40 against the weight by the urging force of the torsion coil spring 42a (see FIG. 12).

  Then, one end t1 of the tissue T is positioned above the upper end (the right end in FIG. 15A) of the dust collecting basket 41, and the one end t1 of the tissue T is folded back toward the outside of the dust collecting basket 41. Further, as shown in FIG. 15A, the upper edge 41g of the dust collecting basket 41 is hooked on the claw 66b protruding from the dust collecting case 40 so that the upper part of the tissue T is separated from the dust collecting case 40 and the dust collecting case. Put it in the basket 41. Then, the tissue T is overlapped along the inner surface of the dust collecting basket 41. Incidentally, by reducing the size of the dust container 30 and the like, the other end t2 of the tissue T protrudes to the hinge part 54 below the dust collection basket 41.

  Then, as shown in FIG. 15B, by closing the lid 50, the other end t <b> 2 of the tissue T is folded, and the folded portion of the tissue T is sandwiched between the dust collection basket 41 and the lid 50. . In addition, the upper part of the tissue T is also sandwiched between the dust collecting basket 41 and the lid 50.

  As described above, in the vacuum cleaner 100, the tissue T located at the peripheral portion of the dust collecting basket 41 is sandwiched and held by the lid portion 50, thereby collecting dust when the vacuum cleaner 100 is used (at the time of suction). It is possible to prevent inconveniences such as accumulation of dust between the dust collecting basket 41 and the tissue T due to the tissue T positioned on the inner wall surface of the car 41 turning over.

  In the vacuum cleaner 100, the opening 40t is provided on the lower surface 40b2 different from the opening surface M1 of the dust collecting case 40, thereby preventing the opening 40t from being blocked by the tissue T when the lid 50 is closed. can do.

  Moreover, in the vacuum cleaner 100, since the hinge part 54 was provided in the lower surface (the lower surface 40a2 of the dust collection case 40, the lower surface 50c1 of the cover part 50) of the dust accommodating part 30, the opening angle when the cover part 50 was opened is set. A large amount can be secured, and the tissue T can be easily attached.

  Moreover, the cover part 50 of the dust accommodating part 30 has the substantially half-moon shaped bottom plate 50c (refer FIG. 14) corresponding to the outer peripheral surface 50d (refer FIG. 14) where the front surface curved, and the lower surface 50c1 of this bottom plate 50c is dust. It is arranged to face the upper surface of the separation part 20. Note that the position of the hinge portion 54 is not limited to the above-described configuration.

As a result, in a state where the dust separation unit 30 is mounted on the cleaner body 1, the release button 62 is pressed so that the engaged protrusion 56 of the lid 50 and the lock member 66 of the dust collecting case 40 Even if the lock is released between the two, the lower surface 50c1 of the bottom plate 50c of the lid 50 is brought into contact with the dust container 20 and the opening operation of the lid 50 is restricted, so that the lid 50 does not open. .
Therefore, the lid 50 can be opened only after the dust container 30 is removed from the cleaner body 1. Therefore, the release button 62 can be prevented from being accidentally pressed and the lid 50 can be prevented from being opened while the electric vacuum cleaner 100 is in use. Further, there is no need to provide a cover or the like that prevents the release button 62 from being pressed when the dust container 30 is attached to the cleaner body 1.

  FIG. 16 shows a procedure when the lid is opened, (a) is a sectional view showing the state of the hand before the lid is opened, and (b) is a sectional view showing the state of the hand after the lid is opened. .

  When removing the dust container 30 from the cleaner body 1, for example, from the front of the dust container 30, the finger is extended backward, the finger is inserted into the insertion part 61s, the tip of the finger is bent forward, The abdominal surface (the surface on the opposite side of the nail) at the tip of the finger is brought into contact with the lower surface of the upper plate 61a1 of the front plate portion 61a. Further, it may be inserted from above the insertion portion 61s, or may be inserted obliquely behind the insertion portion 61s. In any case, the abdominal surface of the finger (except for the thumb) inserted into the insertion portion 61s contacts the lower surface of the upper plate 61a1 of the front plate portion 61a. Further, the fingers to be inserted may be four fingers excluding the thumb, or may be three fingers or less.

  Then, as shown in FIG. 16B, when the handle 61 is pulled upward, as described above, the engaging portion 64a is retracted into the dust accommodating portion 30, and is engaged with the cleaner body 1. Is released. When the handle 61 is pulled up in this way, the space Q1 (see FIG. 16A) formed between the upper surface 40a of the dust collecting case 40 and the handle 61 is expanded to the space Q2 (see FIG. 16B). Therefore, it becomes easy to put a finger, and the handleability of the dust container 30 can be improved.

  That is, by miniaturizing the vacuum cleaner 100, the dust container 30 is miniaturized, parts around the handle 61 are miniaturized, and a space for inserting a finger is also reduced. However, by making the handle 61 movable as described above, the space Q1 into which the finger is inserted can be expanded to the space Q2, so that even when the size is reduced, the finger can be easily inserted. It becomes possible to insert the dust container 30 to the back, and the dust container 30 can be firmly held by hand.

  Further, the release button 62 is placed in the vicinity of the handle 61 and in the direction in which the tips of the fingers (four fingers excluding the thumb) when the finger is put on the handle 61 are directed, the finger is hooked on the handle 61. In this state, the release button 62 can be pressed with the remaining thumb. Thus, from the operation of removing the dust container 30 from the cleaner body 1, it is possible to perform a series of operations of opening the lid 50 and throwing away the dust with one hand.

  Further, when the handle 61 is pulled up, the flange 61a3 of the handle 61 is hooked on the opening edge of the first recess 60a, thereby restricting the rotation of the handle 61 (see FIG. 16B). ), The pressing force when the release button 62 is pressed with the thumb can be increased, and the release button 62 can be easily pushed.

  FIG. 17 is an enlarged view of a portion A in FIG. In FIG. 17, the main part is illustrated with a bold line. FIG. 17 shows a state where the dust container 30 is attached to the cleaner body 1. In addition, the state shown by a thick line in FIG. 17 corresponds to the positional relationship between the dust container 30 and the cleaner body 1 at the time of mounting.

  The engaging part 64a (protruding part) protrudes toward the cleaner body 1, and the tip of the engaging part 64a is inserted into the engaging hole 1a formed in the cleaner body 1. Specifically, the engaging portion 64a has an upper surface 64a1 that extends linearly toward the cleaner body 1 and faces the engaging hole 1a. A substantially rectangular locking protrusion 64a2 is formed at the tip of the upper surface 64a1. The direction parallel to the upper surface 64a1 when the dust container 30 is mounted on the cleaner body 1 (the direction in which the engaging portion 64a protrudes) corresponds to the mounting direction Z.

  The locking protrusion 64a2 has an upright surface 64a3 orthogonal to the upper surface 64a1. Further, an R-shaped curved surface 64a4 is formed at the tip corner of the locking projection 64a2. In addition, this latching protrusion 64a2 prevents the dust accommodating part 30 from removing from the cleaner body 1 when the cleaner body 1 is turned downward. That is, the upper end portion of the rising surface 64a3 of the locking projection 64a2 is brought into contact with and locked to the lower end portion of the inner wall surface 1b of the engagement hole 1a, so that the dust container 30 of the cleaner body 1 is directed downward. Sometimes, the engaging portion 64a and the engaging hole 1a are engaged so that the dust accommodating portion 30 does not fall out of the cleaner body 1.

  Further, the upper surface 64a1 of the engaging portion 64a is disposed with a predetermined gap S10 from the engaging hole 1a of the cleaner body 1. As described above, the predetermined gap S10 is set to a distance at which the locking protrusion 64a2 can be locked in the engagement hole 1a. The upper surface 64a1 and the surface of the engagement hole 1a facing the upper surface 64a1 are configured to coincide with the mounting direction Z and be parallel to each other. The upper surface 64a1 is located below the engagement hole 1a.

  FIG. 18A is a schematic diagram showing a range in which a dust container with an inclined axis can be extracted, FIG. 18B is an operation diagram when the extraction direction is greater than 90 degrees with respect to the mounting direction, and FIG. Fig. 4 is an operation diagram when the extraction direction is 90 degrees with respect to the mounting direction, and Fig. 3D is a schematic diagram showing a range in which the dust container can be extracted with the axis in the vertical direction. The extraction direction means the direction in which the dust container 30 is extracted from the cleaner body 1.

  As shown in FIG. 18 (a), in the case of a vacuum cleaner provided with a dust container 30 inclined backward, the removal direction is within the range of the angle W1 (excluding 90 degrees with respect to the mounting direction Z). The dust container 30 can be extracted from the cleaner body 1. In FIG. 18, for the sake of convenience of explanation, the locking projection 64a2 will be described in a state not shown.

  For example, as shown in FIG. 18B, when the removal direction of the dust container 30 is upward in the vertical direction, when the engaging portion 64a comes into contact with the engaging hole 1a, the engaging portion 64a is perpendicular to the engaging portion 64a. An upward force F acts in this direction. At this time, a component force F1 in a direction perpendicular to the upper surface 64a1 (the axial direction of the dust container 30) with respect to the force F and a direction parallel to the upper surface 64a1 (of the dust container 30) A component force F2 in a direction perpendicular to the axial direction is generated. By generating the component force F2 in this way, it is possible to operate the engaging portion 64a in the direction in which the engaging portion 64a is pulled out from the engaging hole 1a (opposite to the mounting direction Z).

  Thus, when the removal direction of the dust container 30 is larger than 90 degrees with respect to the mounting direction Z, even if the main body of the dust container 30 is gripped and pulled, the engaging part Since 64a immediately comes out of the engagement hole 1a, the dust container 30 is not lifted together with the cleaner body 1.

  On the other hand, as shown in FIG. 18C, when the pulling direction is an angle of 90 degrees with respect to the mounting direction Z (comparative example), when the engaging portion 64a comes into contact with the engaging hole 1a. A force F10 in a direction perpendicular to the upper surface 64a1 acts on the engaging portion 64a. A reaction force F11 in the opposite direction acts on the upper surface 64a1 of the engaging portion 64a with respect to the force F10 at this time. That is, the entire load of the cleaner body 1 acts on the engaging portion 64a, and the engaging portion 64a does not come out of the engaging hole 1a.

  Moreover, as shown in FIG.18 (d), it is applicable also to the electrical cleaner attached so that the axis | shaft G10 of the dust accommodating part 30 may become a perpendicular direction with respect to the cleaner body 1. As shown in FIG. In this case, the dust container 30 can be extracted from the cleaner body 1 by simply pulling the dust container 30 while holding the outer peripheral surface within the range of the angle W2.

  As shown in FIGS. 18 (a) and 18 (d), the positional relationship between the engaging portion 64a and the engaging hole 1a so that the dust container 30 is removed from the cleaner body 1 within the range of angles W1 and W2. As a result, even if the main body portion of the dust container 30 other than the handle 61 is gripped and lifted, the dust container 30 is immediately detached from the cleaner body 1. Therefore, the dust container 30 is not lifted together with the cleaner body 1.

  Moreover, in the vacuum cleaner 100, by forming the locking protrusion 64a2 locked to the engaging hole 1a at the tip of the engaging portion 64a, in the state where the dust container 30 is attached to the vacuum cleaner body 1, for example, Even if the cleaner body 1 is tilted so that the dust container 30 faces downward, the dust container 30 can be prevented from falling off the cleaner body 1.

  Further, the electromagnetic cleaner 100 includes the compression coil spring 65 (biasing member) that biases the engaging portion 64a toward the mounting direction Z, so that when the dust container 30 is mounted on the vacuum cleaner body 1. Instead of inserting the engaging portion 64a straight into the engaging hole 1a, the engaging portion 64a is rotated with the bottom surface side of the dust accommodating portion 30 as a fulcrum so that the engaging portion 64a is inclined with respect to the mounting direction Z. Even when the engagement portion 64a is about to be inserted, the engagement portion 64a is retracted against the urging force of the compression coil spring 65, so that the engagement portion 64a can be inserted into the engagement hole 1a. That is, even when the engaging portion 64a is not inserted in parallel with the mounting direction Z with respect to the engaging hole 1a, the engaging portion 64a can be easily inserted into the engaging hole 1a.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the case of the convex engaging portion 64a on the dust accommodating portion 30 side and the engaging hole 1a into which the engaging portion 64a is inserted on the cleaner body 1 side are described as examples. On the contrary, a configuration in which a convex engaging portion is formed on the cleaner body 1 side and an engaging hole into which the engaging portion is inserted on the dust accommodating portion 30 side may be formed.

In the above-described embodiment, the configuration in which the dust container 30 and the dust separator 20 are separated has been described as an example. However, the dust container 30 and the dust separator 20 are integrally formed. May be. In this case, the integrated structure is used as a dust container, and a hinge portion (corresponding to the hinge portion 54) is provided on the lower surface of the integrated structure so that the hinge portion is in the cleaner body 1. It may be configured to be accommodated.
