Description

  The present invention relates to a vacuum cleaner provided with a cyclone type dust collector.

  The electric vacuum cleaner has an electric blower that generates an air flow for sucking air inside the main body, and a cyclone dust collector (removably installed in front of the electric blower). ).

  The dust collector includes a dust collecting container having a circular cross section having an opening surface on an upper surface. In addition, an inlet is formed in the upper part of the dust collecting container so that air flows in the direction of the tangent to the inner peripheral surface of the dust collecting container. And the dust collection filter which covers the opening surface of a dust collection container is attached to the upper part of a dust collection container via the filter holding | maintenance part. Furthermore, a cover part that forms a part of the exterior of the vacuum cleaner is provided on the upper part of the filter holding part. A cover part opens the dust collector exhaust port connected to an electric blower in a rear-end surface.

  On the lower surface of the filter holding part, an inner cylinder having an air flow outlet on the peripheral surface and having an internal space communicating with the dust collecting filter is arranged so as to be coaxial with the dust collecting container. A mesh-like filter (mesh filter) in which a small gap (hole) is formed is attached to the outlet of the inner cylinder.

  An air flow path is formed between the lower end of the inner cylinder and the inner surface of the dust collecting container, and a partition member for vertically partitioning the inside of the dust collecting container is detachably attached. The partition member has a disk-shaped disk portion extending in the radial direction and a cylindrical tube portion continuously provided on the periphery of the disk portion. A cylindrical part forms an outer peripheral surface in a cylindrical surface, and opposes the inner peripheral surface of a dust collecting container.

  In the dust collector, the cover part, the filter holding part, the inner cylinder, the partition member, and the dust container can be integrally attached to and detached from the main body part of the vacuum cleaner. And a cover part, a filter holding | maintenance part, an inner cylinder, and a partition member can be attached or detached with respect to a dust collecting container.

  In the vacuum cleaner having the above-described configuration, the dust flows into the dust collecting container of the dust collecting apparatus from the inlet with the air by driving the electric blower. The air that has flowed into the dust collecting container swirls within the dust collecting container, and large dust is separated by centrifugal force and accumulated on the bottom of the dust collecting container.

  At this time, the backflow of the dust accumulated on the bottom of the dust collecting container to the upper part of the dust collecting container is suppressed by the disk part of the partition member and the cylindrical part connected to the peripheral part of the disk part. The airflow from which the large dust has been removed flows into the inner cylinder through the outlet. A mesh filter is disposed at the outlet, and among the dust that has not been separated by the swirling airflow, small dust, hair, lint, etc. are collected by the mesh filter.

  The airflow flowing from the outlet to the inner cylinder passes through the dust collection filter and flows out of the dust collector from the dust collector exhaust port. When the airflow passes through the dust collection filter, fine dust that could not be collected by the mesh filter is collected by the dust collection filter. The air that flows out from the dust collector passes through the electric blower and is exhausted to the outside.

  Then, the dust collecting device can be removed from the main body of the vacuum cleaner, and the dust collected in the dust collecting container can be removed by removing the dust collecting container (see, for example, JP-A-2002-315701).

As shown in FIGS. 1 and 2, the vacuum cleaner A includes a main body 1, a connection hose 2, an extension pipe 3, a suction port body 4, a power cord 5, a dust collector 6, and an electric blower. (Not shown).

  A dust collector 6 and an electric blower (not shown) are incorporated in the main body 1. A power cord 5 is provided on the back surface of the main body 1 so that it can be pulled out and stored. And the power plug 51 is attached to the front-end | tip of this power cord 5, and electric power is supplied to the vacuum cleaner A (mainly electric blower) by inserting the power plug 51 in the outlet of a commercial power source.

  A connection port 101 is formed on the front surface of the main body 1, a flexible connection hose 2 is connected to the connection port 101, and an extension pipe 3 is connected to the tip of the connection hose 2. A suction port body 4 having a suction port (not shown) facing the floor surface is provided at the tip of the extension pipe 3. Further, the extension pipe 3 is provided with a pipe gripping portion 31 and an operation portion 32. When the user operates the operation unit 32, the electric vacuum cleaner A starts (stops) operation. And in the state which the vacuum cleaner A is operate | moving, the cleaning operation of the vacuum cleaner A is performed because a user hold | grips the holding part 31 and moves the suction inlet body 4. FIG.

  The main body 1 is covered with a main body cover 10. A dust collector 6 is disposed at the front of the main body 1 and an electric blower is disposed at the rear. A connection port 101 for connecting the connection hose 2 (see FIG. 1) is opened on the front surface of the main body cover 10, and an exhaust port 102 is opened on the back surface. A dust collection chamber is provided in front of the electric blower inside the main body 1, and a cyclonic dust collector 6 is detachably disposed in the dust collection chamber. As will be described in detail later, the dust collecting container 61 of the dust collecting device 6 is formed of a transparent resin, and the main body cover 10 is formed with a window portion 103 for viewing the inside of the dust collecting container 61.

  As shown in FIG. 2, the dust collector 6 includes an inflow port 613 communicating with the connection port 101 and a dust collector exhaust port 602 through which an airflow from which dust is removed flows. The dust collector exhaust port 602 and the electric blower are connected by a duct.

  As shown in FIG. 2, a cover portion 60 that is continuous with the main body cover 10 and forms a part of the exterior of the main body portion 1 is disposed on the dust collector 6. The dust collector 6 includes a cover part 60, a dust collection container 61, a filter holding part 62, an inner cylinder 63, and a partition member 64. The cover part 60, the filter holding part 62, the inner cylinder 63, and the partition member 64 are integrated, and the dust collecting container 61 is detachably attached to them.

  The dust collection container 61 is formed of a transparent resin so that the inside can be observed. The dust collecting container 61 is a bottomed cylindrical member having an upper opening 611. An inlet 613 that communicates with the connection port 101 (see FIG. 1) and into which the airflow from the connection hose 2 flows is formed on the upper peripheral surface of the dust collecting container 61. Inside the dust collecting container 61, an airflow flows in the circumferential direction of the inner peripheral surface via the inflow port 613, and a swirling airflow is formed inside the dust collecting container 61. That is, the inflow port 613 is formed so that a swirling airflow is formed inside the dust collecting container 61. Thereby, a cyclone type dust collector is formed.

  The filter holding unit 62 holds a dust collection filter 621 formed by a pleated filter having a circular shape in plan view. An inner cylinder 63 is attached to the lower surface of the filter holding part 62 so as to protrude.

  The dust collection filter 621 is a filter for collecting fine dust that cannot be collected by the mesh filter attached to the inner cylinder 63. The filter holding unit 62 is provided with a dust removal mechanism (not shown) for removing dust accumulated in the dust collection filter 621 in order to prevent clogging of the dust collection filter 621. When the dust removal mechanism moves along the circumferential direction of the filter holding unit 62, it applies an impact to the dust collection filter 621 of the filter holding unit 62 and drops the accumulated dust downward.

  The inner cylinder 63 is a cylindrical member arranged coaxially with the dust collecting container 61, and an airflow outlet 630 is provided on the circumferential surface. The outflow port 630 communicates with the exhaust port 102 (see FIG. 1) provided on the back surface of the main body 1. Further, the inner cylinder 63 is externally fitted to a later-described cage portion 65 attached to the partition member 64. The inner cylinder 63 communicates with the filter holding part 62.

  The partition member 64 is a member that forms an air flow path between the inner surface of the dust collection container 61 and partitions the inside of the dust collection container 61 up and down, and is connected to the inner cylinder 63. The partition member 64 includes a disc portion 641, a cylindrical tubular portion 642 that extends upward and downward from the periphery of the disc portion 641, and a projecting portion 643 that projects downward from the lower surface of the disc portion 641 and communicates with the inner cylinder 63. doing. Further, the partition member 64 includes a car portion 65 attached to the upper surface of the disc portion 641.

  The cylindrical portion 642 has a cylindrical shape, and the inner peripheral surface of the dust collecting container 61 and the outer peripheral surface of the cylindrical portion 642 are formed substantially in parallel. Thereby, the channel area of an air channel can be made substantially uniform.

  Alternatively, a spiral ridge may be formed on the outer peripheral portion of the cylindrical portion 642 so that the cylindrical portion 642 can be rotated. Even when the dust is large and remains between the cylindrical portion 642 and the inner peripheral surface of the dust collecting container 61, the cylindrical portion 642 can be rotated to send the dust downward with the ridges. Thereby, dust is not easily clogged between the inner peripheral surface of the dust collecting container 61 and the outer peripheral surface of the cylindrical portion 642, and the flow path of the swirling airflow is not easily blocked. From this, the fall of the dust collection function of the dust collector 6 can be suppressed.

  The protruding portion 643 is engaged with the peripheral surface of the holding shaft portion 614 formed integrally with the bottom portion of the dust collecting container 61. As a result, a frame portion having a circular cross section standing at the central portion below the partition member 64 is formed. A part of the peripheral surface of the holding shaft portion 614 is provided with a shield material (not shown) made of rubber (not limited to rubber as long as it is highly airtight). The shield material can secure the airtightness between the protruding portion 643 and the holding shaft portion 614, and can more reliably prevent the outflow of fine dust.

  By setting it as the above structures, the inside of the filter holding | maintenance part 62, the inner cylinder 63, and the protrusion part 643 will be in a communication state. As a result, the fine dust that has fallen into the inner cylinder 63 from the dust collection filter 621 by driving the dust removal mechanism is collected in the lower portion of the protrusion 643. Since the holding member 643 is in close contact with the holding shaft portion 614, the fine dust is prevented from flowing into the airflow flowing through the dust collecting container 61.

  In the vacuum cleaner A configured as described above, the dust on the floor surface is sucked from the suction port 4 by driving the electric blower, and the air flow including the dust flows through the extension pipe 3 and the connection hose 2. The airflow including dust flows into the dust collecting container 61 of the dust collecting device 6 through the connection port 101 and the inflow port 613, and forms a swirling airflow in the dust collecting container 61. The relatively large dust contained in the airflow is separated by the centrifugal force of the swirling airflow, and is deposited on the bottom of the dust collecting container 61.

  Also, the dust accumulated on the bottom of the dust collecting container 61 is prevented from flowing back to the upper part of the dust collecting container 61 by the disc part 641 and the cylindrical part 642 of the partition member 64. The airflow from which large dust has been removed enters the inner cylinder 63 from the outlet 630, rises inside the inner cylinder 63, and flows into the filter holding unit 62. At this time, dust contained in the airflow is collected by a mesh filter and a dust collection filter 621 (not shown). The airflow that has passed through the dust collection filter 621 flows out of the dust collector 6 through the dust collector exhaust port 602.

  Further, when the grip portion 601 is pulled up, the dust collector 6 is detached from the main body 1 of the electric vacuum cleaner A. Furthermore, the dust accumulated on the bottom of the dust collecting container 61 can be discarded by detaching the dust collecting container 61 from the filter holding part 62, the inner cylinder 63 and the partition member 64. At this time, dust due to dust removal of the dust collection filter 621 accumulated at the lower portion of the protruding portion 643 of the partition member 64 is also discarded.

  Next, the partition member and inner cylinder which have the cage | basket part which are the principal parts of the vacuum cleaner concerning this invention are demonstrated with reference to drawings.

(First embodiment)
3 is a perspective view showing the inner cylinder and the partition member, FIG. 4 is an exploded perspective view showing the inner cylinder and the partition member, FIG. 5 is a sectional view of the partition member, and FIG. It is the perspective view seen from the bottom, and FIG. 7 is a perspective view of the partition member in the state which removed the cage | basket part.

  As shown in FIG. 4, the car portion 65 is attached and fixed to the upper surface of the flat plate portion 641 of the partition member 64. The cage portion 65 includes a lower annular portion 651 fixed to the flat plate portion 641, an upper annular portion 652 disposed above the lower annular portion 651, a lower annular portion 651, and an upper annular portion. And a column portion 653 for connecting to the main body 652. In addition, although the cage | basket part 65 shown in FIG. 4 etc. has four support | pillar part 653 arrange | positioned at equal intervals in the circumferential direction, it is not limited to this.

  Further, as shown in FIG. 5, the lower annular portion 651 is fixed to the flat plate portion 641 of the partition member 64. The lower annular portion 651 is fixed to the flat plate portion 641 so that the central axis of the partition member 64 passes through the center. And the support | pillar part 653 is arrange | positioned so that it may become in parallel with the central axis of the partition member 64. FIG. The lower ring portion 651 is fixed to the flat plate portion 641 by a well-known method such as fitting with a claw and a groove, so that the cage portion 65 is not dropped from the flat plate portion 641 in normal use. Fixed.

  Moreover, the support | pillar part 653 is a member for preventing fibrous dusts, such as hair and a waste thread, getting entangled with the inner cylinder 63, and what has a fixed width | variety in radial direction is preferable.

  Next, the inner cylinder 63 will be described. As shown in FIG. 4, the inner cylinder 63 and the cage portion 65 are configured to be detachable in the axial direction. As shown in FIG. 6, the inner cylinder 63 includes a disc-shaped bottom surface portion 631 having an opening at the center, a flange portion 632 formed at the top of the bottom surface portion 631 and extending in the entire circumferential direction, and a bottom surface portion 631. A plurality (four in this case) of frame portions 633 connecting the outer peripheral portion and the inner peripheral portion of the flange portion 632 and a plurality of (in this case) for pressing the mesh filter are arranged between the adjacent frame portions 633. Eight) filter holders 634 are provided.

  The bottom surface portion 631 contacts and is fixed to the flat surface portion 641 of the partition member 64. The partition member 64 is fixed by engaging a locking claw formed near the opening and an engaging portion 645 formed on the flat surface portion 641 on the lower surface of the bottom surface portion 631. Details of the engagement between the inner cylinder 63 and the partition member 64 in the locking portion 635 and the engaging portion 645 will be described.

  The flange portion 632 is fixed in contact with the lower surface of the filter holding portion 62. The inner cylinder 63 may be fixed to the filter holding part 62 integrally (so as not to be detached) or may be supported in a rotatable state. When the dust accumulated on the bottom of the dust collecting container 61 is discarded, it is only necessary to be connected so as not to be detached from the filter holding unit 62.

  The frame portion 633 is a support member (frame member) that supports the bottom surface portion 631 and the flange portion 632 so as to maintain a constant distance. In the inner cylinder 63, four frame portions 633 are provided and are arranged at equal intervals in the circumferential direction. In addition, a total of eight filter holding portions 634 are provided between two adjacent frame portions 633. The filter pressing portion 634 is arranged so as to divide the interval between adjacent frame portions 633 in the circumferential direction into three equal parts. In addition, the number of the frame part 633 and the filter pressing part 634 is an example, and is not limited to this.

  A gap between the frame portion 633 and the filter pressing portion 634 or between the adjacent filter pressing portions 634 serves as an outlet 630. The outflow port 630 is covered with a mesh filter, and the mesh filter is attached to the filter holding portion 634. When the electric blower is driven and air flows into the dust collecting container 61, the airflow flows into the filter holding part 62 from the outlet 630 through the inner cylinder 63. By providing the filter pressing portion 634, it is possible to suppress the mesh filter from being sucked into the inner cylinder 63 by the airflow.

  When fibrous dust such as hair and lint is contained in the airflow flowing in from the inflow port 613, the airflow wraps around the outer periphery of the cage portion 65. The fibrous dust wraps around the car portion 65 and hardly wraps around the inner cylinder 63. When the dust accumulated in the dust collecting container 61 is thrown away, the inner cylinder 63 and the cage portion 65 are separated, so that fibrous dust such as hair and lint is not a troublesome inner cylinder 63 but a basket. It is wound around part 65. As described above, the cage 65 has a large gap between the four support columns 653, and the wound fibrous dust can be easily cut with a cutting tool such as scissors. Further, it is possible to prevent the surrounding members from being damaged by the cutting tool. Thereby, the troublesomeness of the user at the time of disposal of dust can be reduced.

  On the other hand, the mesh filter can be slightly deformed, that is, is arranged in a stretched state so as to be recessed in the inner cylinder 63. For example, when the airflow flows through the outlet 630, the mesh filter is pushed and deflected by the airflow.

  When the inner cylinder 63 provided with such a mesh filter and the partition member 64 are connected, if the outlet 630 of the inner cylinder 63 and the column portion 653 of the cage portion 65 overlap in the radial direction, the column portion 653 It becomes easy to make a gap between mesh filters. When fibrous dust such as hair and lint flows into the gap, fibrous dust such as hair and lint is caught in the gap between the inner cylinder 63 and the cage portion 65, and a part of the fibrous dust is captured. Entangled with mesh filter.

  As described above, when the fibrous dust is entangled with the mesh filter, when the inner cylinder 63 and the cage portion 65 are separated, the fibrous dust is caught on both the inner cylinder 63 and the cage portion 65, and the fibrous dust is collected. It may take time to remove.

  In order to suppress such catching of fibrous dust, in the dust collector 6, when the cage portion 65 is externally fitted to the inner cylinder 63, the frame portion 633 of the inner cylinder 63 and the column portion 653 of the cage portion 65. Are overlapped in the radial direction. The frame portion 633 and the column portion 653 are columns for supporting the inner cylinder 63 and the cage portion 65, respectively, and are strong members that are difficult to deform. And by arrange | positioning so that such a strong member may adjoin, it is hard to make a clearance gap between the inner cylinder 63 and the cage | basket part 65, and it can suppress that hair, lint, etc. are caught.

  Hereinafter, a method of overlapping the frame portion 633 of the inner cylinder 63 and the support column portion 653 of the cage portion 65 in the radial direction will be described with reference to the drawings. As shown in FIG. 6, the lower surface of the bottom surface portion 631 of the inner cylinder portion 63 is provided with a locking portion 635 formed on an arc with the opening interposed therebetween. The locking portion 635 includes an arcuate convex portion 636 having a central angle extending 90 ° downward in the axial direction, and a claw portion 637 projecting outward in the radial direction of the inner cylinder 63 from the axial end of the convex portion. . The claw portion 637 has a fan shape. Note that the center angle of the convex portion 636 is not necessarily 90 °, and may be 90 ° or less.

  As shown in FIG. 7, in the partition member 64, a cylindrical rib 644 is formed on the upper surface of the flat plate portion 641, and an engaging portion 645 is provided on the inner peripheral surface of the rib 644. The engaging portion 645 has a shape with which the engaging portion 635 can be engaged, and has one end in the circumferential direction of the engaging portion 645 (the tip in the clockwise direction in plan view in the partition member 64 shown in FIG. 7). A stopper portion 646 with which the claw portion 637 comes into contact is formed at the side end). In addition, the center angle of the engaging part 645 is 90 degrees or less. That is, the center angle of the insertion port 647 that is a gap between adjacent engaging portions 645 may be 90 ° or more. Further, the locking portion 635 and the engaging portion 645 constitute an example of a connecting means.

  The connection between the inner cylinder 63 and the partition member 64 is performed as follows. The inner cylinder 63 is arranged so as to be coaxial with the car portion 65, and the inner cylinder 63 and / or the partition member 64 are moved in the axial direction so that the car portion 65 fits the inner cylinder 63 externally. When the bottom surface portion 631 of the inner cylinder 63 approaches the flat plate portion 641 of the partition member 64, the inner tube 63, the partition member 64, and the central axis are arranged so that the claw portion 637 of the inner cylinder 63 overlaps the insertion port 647 in the axial direction. Rotate relative to

  In this state, by bringing the bottom surface portion 631 and the flat plate portion 641 closer, the positional relationship in which the locking portion 635 and the engaging portion 645 can engage with each other, that is, the axial position of the engaging portion 645 is the bottom surface portion 631. And between the claw portions 637. And the claw part 637 and the engaging part 645 overlap with an axial direction by rotating the inner cylinder 63 clockwise with respect to the partition member 64. The claw portion 637 comes into contact with the stopper portion 646 so that the rotation of the inner cylinder 63 can be restricted.

  The inner cylinder 63, the partition member 64, and the cage portion 65 are formed so that the frame portion 633 and the column portion 653 overlap in the radial direction when the claw portion 637 comes into contact with the stopper portion 646. Thereby, by engaging the inner cylinder 63 and the partition member 64, the frame part 633 and the support | pillar part 653 can be piled up in radial direction, and it can suppress that fibrous dust is caught.

  In addition, at least one of the engaging portion 645 or the claw portion 637 is formed to be inclined with respect to a surface orthogonal to the axis, and the inner tube 63 is rotated with respect to the partition member 64, whereby the engaging portion 645 and You may make it a contact pressure with the nail | claw part 637 become high. Thereby, it can suppress that the inner cylinder 63 rotates with respect to the partition member 64, and can suppress that the frame part 633 and the support | pillar part 653 shift | deviate in the circumferential direction.

  By setting it as the above structure, the inner cylinder 63 and the partition member 64 can be connected reliably, and the malfunction by an assembly can be suppressed. Moreover, the frame part 633 and the support | pillar part 653 overlap in radial direction by attaching the inner cylinder 63 and the partition member 64 correctly. Thus, when the dust collecting device 6 is assembled, the frame portion 633 and the support column portion 653 always overlap in the radial direction, and even if fibrous dust such as hair and lint flows from the inlet 613 along with the airflow, Can be prevented from being caught between the inner cylinder 63 and the car portion 65 and becoming difficult to remove.

  Further, the engaging portion 635 and the engaging portion 645 engage with each other, so that the inner cylinder 63 and the partition member 64 are axially moved (especially when dust accumulated in the dust collecting container 61 is discarded). Shifting can be suppressed.

  Further, when the airflow from the inlet 613 is blown to the outlet 630 of the inner cylinder 63, fine fibrous dust such as hair may pierce the mesh filter. In this case, it becomes difficult to remove fibrous dust from the mesh filter. For this reason, the inflow port 613 is preferably formed so that the inflowing air current does not blow directly against the inner cylinder 63.

(Second Embodiment)
Another example of the dust collector used in the vacuum cleaner according to the present invention will be described with reference to the drawings. FIG. 8 is an exploded perspective view of an inner cylinder and a partition member used in the dust collector. As shown in FIG. 8, the inner cylinder 63 includes a cylindrical portion 638 extending downward from the bottom surface portion 631 as a locking portion, and a concave groove 639 is formed on the peripheral surface of the cylindrical portion 638. Further, the inner surface of the protruding portion 643 is used as a locking portion, and the cylindrical portion 638 and the inner surface of the protruding portion 643 constitute an example of a connecting means.

  When the inner cylinder 63 is securely attached to the partition member 64, the cylinder portion 638 is inserted while being in contact with the inner surface of the protruding portion 643. A protrusion 648 is formed on the inner peripheral surface of the protrusion 643 so as to engage with the groove 639 when the position of the inner cylinder 63 with respect to the partition member 64 is an accurate position.

  The protrusions 648 formed on the inner peripheral surface of the protruding portion 643 are positions where the inner tube 63 is attached to the partition member 64 and engages with the groove 639 when the frame portion 633 and the column portion 643 overlap in the radial direction. Is formed. Thus, by providing the protruding line 648 and the recessed groove 639, there is a slight impact when the protruding line 648 and the recessed groove 639 are engaged.

  By making the outer peripheral surface of the cylinder part 638 contact the inner peripheral surface of the projecting part 643, the central axes of the inner cylinder 63 and the partition member 64, that is, the inner cylinder 63 and the cage part 65 can be easily aligned. In addition, the inner cylinder 63 and the partition member 64 are relatively rotated until an impact is generated when the protrusion 648 and the groove 639 are engaged with each other, so that the frame portion 633 and the column portion 653 are accurately positioned. Can be overlapped in the radial direction. Further, the engagement between the ridge 648 and the groove 639 allows the inner cylinder 63 and the partition member 64 to shift in the axial direction (especially when the dust accumulated in the dust collecting container 61 is discarded). Can be suppressed.

  In the present embodiment, the inner peripheral surface of the protruding portion 643 and the outer peripheral surface of the cylindrical portion 638 are slidable in the circumferential direction (circular cross section), but the inner peripheral surface of the protruding portion 643 and the cylindrical portion 638 are The cross-sectional shape with the outer peripheral surface may be a flat shape such as an ellipse. By adopting a flat shape, it is possible to attach only at the correct position, and it is possible to suppress the occurrence of attachment failure.

  In the said embodiment, although the vacuum cleaner A is formed in the canister type | mold to which the suction inlet body 4 is connected via the connection hose 2 to the main-body part 1 which incorporates an electric blower, the suction inlet body 4 is formed in the main-body part 1. It may be a vertical vacuum cleaner provided integrally.
