The structure of each part of the vacuum cleaner 1 will be described in more detail below.

<<Regarding the configuration of the dust collection unit 20>>
The dust collector 20 will be described in detail below with reference to FIGS. 3 to 6. FIG. The dust collection part 20 is provided detachably with respect to the main body 10 of the cleaner. The dust collection section 20 includes a dust collection container 50 , a centrifugal separation section 100 , a filter 70 (not shown in FIG. 5 ), a filter support section 80 and a cover section 90 . The dust collector 20 is a so-called cyclone dust collector. That is, the dust collecting section 20 introduces air from an inlet (first inlet 68) provided in the dust collecting container 50, forms a whirling airflow in the dust collecting container 50, and then collects the air in the process of discharging the air. It is considered dust-proof. The dust collector 20 can adopt a so-called single-stage separation system or a multi-stage separation system of three or more stages, but in the present embodiment, a so-called two-stage centrifugal separation system is adopted. Therefore, the dust collecting unit 20 can perform centrifugal separation in two stages, thereby centrifugally separating small dust and large dust and collecting the dust.

The dust collection container 50 is a container comprising an outer container 52 , an inner container 54 , a bottom portion 58 and a lid portion 106 . The dust collection container 50 includes an inner container 54 arranged inside an outer container 52, and a bottom portion 58 attached to one side (bottom side) of the outer container 52 in the axial direction to close it. A lid portion 106 is attached to the upper end side).

The outer container 52 is a cylindrical container. The outer container 52 has a dust collection chamber 62 on one side (bottom side) in the axial direction and a centrifugal separation chamber 64 on the other side (upper end side) in the axial direction via a partition wall 60 (umbrella-shaped portion) in the middle portion in the axial direction. It is divided into The partition wall 60 can suppress dust in the dust collection chamber 62 from being stirred up by the whirling airflow formed in the centrifugal separation chamber 64 .

The partition wall 60 is formed in an umbrella shape. The partition wall 60 is formed so as to slope downward from the radially inner side (axial side) of the outer container 52 toward the outer side. The partition wall 60 has an inner opening 66a in the radial center portion (axial side) and an outer opening 66b (see FIG. 4) in the circumferential direction. The outer container 52 is formed to communicate with the dust collection chamber 62 and the centrifugal separation chamber 64 via an inner opening 66a and an outer opening 66b. That is, the inner opening 66 a is a substantially circular opening formed to communicate with the bottom side of the centrifugal separation section 100 . The outer opening 66b is located radially outward of the inner opening 66a and is an opening formed by cutting out a portion of the partition wall 60 .

As shown in FIGS. 3 and 4, the outer container 52 has a first inlet 68 on its outer periphery. The first inlet 68 opens at an axially intermediate portion of the outer container 52 (closer to the centrifugal separation chamber 64 than the partition wall 60). Therefore, the first inlet 68 communicates with the centrifugal separation chamber 64 . The first inlet 68 has a rectangular opening at an inlet portion 68 a that extends cylindrically from the outer surface of the outer container 52 . The inflow portion 68a extends so as to incline from the end in the circumferential direction toward the center. In addition, the first inlet 68 is provided at a position corresponding to an outer peripheral guide rib 116 provided in the centrifugal separation outer cylinder 102 of the centrifugal separation unit 100, which will be described later, and the outer peripheral guide rib 116 forms part of the air passage together with the inlet 68a. , extending to abut the inner peripheral surface of the outer container 52. As shown in FIG. As a result, the outer container 52 allows air to flow into the centrifugation chamber 64 along the inner peripheral surface of the outer container 52 via the first inlet 68, and the air tends to flow in one direction. The direction is defined by the outer peripheral guide rib 116 .

The inner container 54 is a container arranged inside the outer container 52 . The inner container 54 is arranged in a dust collection chamber 62 below the partition wall 60 . The inner container 54 is arranged so that the outer container 52 and the axial center position are substantially aligned. The inner container 54 divides the inner space of the dust collection chamber 62 into an outer dust collection chamber 72 and an inner dust collection chamber 74 . The inner container 54 is open at one end (bottom side) in the axial direction. In addition, the inner container 54 communicates with an inner opening 66a provided in the partition wall 60 on the other end side (upper end side) in the axial direction.

The inner container 54 has an inner container reduced-diameter portion 76 tapered from the upper end side to the axially middle portion. Further, the inner container 54 has a cylindrical shape with a substantially uniform opening diameter below the inner container reduced diameter portion 76 . The inner container 54 is airtightly connected to the centrifugal separation outer cylinder 102 of the centrifugal separation section 100 via a first seal portion S1, which will be described in detail later.

The bottom portion 58 closes the bottom portion of the dust collection container 50 (on the dust collection chamber 62 side). The bottom portion 58 can open and close the bottom portion of the dust collection container 50 . In this embodiment, the bottom portion 58 is connected to the dust container 50 via a hinge 82, as shown in FIG. Further, the bottom portion 58 can be fixed to the dust container 50 with the bottom portion of the dust container 50 closed by a lock portion 84 located on the opposite side of the dust container 50 in the radial direction with respect to the hinge 82 . there is

A swivel suppression rib 86 is provided on the bottom portion 58 . The swirl restraint rib 86 is arranged inside the outer dust collection chamber 72 formed between the inner container 54 and the outer container 52 in a state where the bottom portion of the dust collection container 50 is closed by the bottom portion 58 . ing. The swirling suppression rib 86 is a rib for suppressing swirling of dust collected in the outer dust collection chamber 72 by swirling air currents formed in the vicinity of the bottom portion 58 . The rotation suppression rib 86 is provided to protrude in the axial direction of the dust container 50 from the inner surface of the bottom portion 58 (the surface facing the inside of the dust container 50 when the bottom portion 58 is closed). Further, a plurality of (in this embodiment, four) rotation suppression ribs 86 are provided in the direction around the axis (circumferential direction) of the dust collection container 50 . A second seal member 88 is provided on the inner surface of the bottom portion 58 . The second seal member 88 constitutes a second seal portion S2, which will be described in detail later. When the bottom portion 58 is closed, the second sealing member 88 is brought into intimate contact with the lower end portion of the inner container 54 to airtightly close the inner container 54 .

The centrifugal separator 100 is a part that centrifuges dust. The centrifugal separation unit 100 includes a centrifugal separation outer cylinder 102 , a centrifugation inner cylinder 104 , a lid section 106 and a support section 108 .

The centrifugation outer cylinder 102 is a cylindrical body capable of accommodating the centrifugation inner cylinder 104 . The centrifugal separation outer cylinder 102 has small holes 114, outer peripheral guide ribs 116 (see FIG. 3), and positioning protrusions 118 on its peripheral surface. The centrifugation outer cylinder 102 is a member that forms a first centrifugation chamber 110 between itself and the outer container 52 of the dust collection container 50 and forms a second centrifugation chamber 112 inside.

The first centrifugal separation chamber 110 can receive air from the outside through the first inlet 68 provided in the outer container 52 of the dust collection container 50 described above. The first centrifugation chamber 110 is an annular space formed between the centrifugation barrel 102 and the outer container 52 of the dust collection container 50 . The first centrifugal separation chamber 110 can generate a whirling airflow by allowing air to flow in the tangential direction of the centrifugation outer cylinder 102 from the first inlet 68 . Thereby, relatively large dust particles contained in the introduced air can be centrifuged (first centrifugal separation). Relatively large dust separated from the air by the first centrifugation falls toward the partition wall 60 forming the bottom of the first centrifugation chamber 110 . Dust falling on the partition wall 60 falls through an outer opening 66b provided in the partition wall 60 and falls into an outer dust collection chamber 72 provided below the partition wall 60 and is collected.

A large number of small holes 114 are provided on the peripheral surface of the centrifugal cylinder 102 . The small hole 114 communicates between a first centrifugation chamber 110 formed on the outside of the centrifugation barrel 102 and a second centrifugation chamber 112 formed on the inside. Therefore, the centrifugal separation section 100 can introduce air from which large dust particles have been collected in the first centrifugal separation chamber 110 into the second centrifugal separation chamber 112 through the small holes 114 .

The outer peripheral guide rib 116 is provided on the peripheral surface of the centrifugation outer cylinder 102 at a position corresponding to the first inlet 68 provided in the outer container 52 of the dust collection container 50 described above. The outer peripheral guide rib 116 guides the air that has flowed into the first centrifugal separation chamber 110 from the first inlet 68 along the outer peripheral surface of the centrifugal outer cylinder 102 and the inner peripheral surface of the outer container 52 in a predetermined direction around the axis. It is intended to guide the flow in the direction.

As shown in FIGS. 5 and 7, the positioning protrusion 118 is a protrusion that protrudes radially outward from the outer peripheral surface of the centrifugation outer cylinder 102 . The positioning protrusions 118 are fitted into the protrusion receiving portions 52a provided on the outer container 52 of the dust container 50 when the centrifugal separation unit 100 is attached to the dust container 50, thereby allowing the centrifugal outer cylinder 102 to be attached to the dust container. Circumferential rotation with respect to 50 can be restricted.

The centrifugation inner cylinder 104 is arranged in a second centrifugation chamber 112 formed inside the centrifugation outer cylinder 102 . A plurality of centrifugation inner cylinders 104 (five in this example) are provided. The centrifugation inner cylinders 104 are arranged substantially evenly in the direction around the axis (circumferential direction) in the second centrifugation chamber 112 . In addition, a plurality of (five in this embodiment) centrifugal separation inner cylinders 104 are integrated at the upper end side by an annularly formed upper wall portion 120 . The centrifugal separation inner cylinder 104 is arranged so that the upper end portion is in contact with the inner peripheral surface of the upper wall portion 120 .

The centrifugal separation inner cylinder 104 has a substantially uniform outer diameter (opening diameter) from the upper end side to the intermediate portion, and has a centrifugal separation reduced diameter portion 122 tapered from the intermediate portion to the lower end side. It is The centrifugation inner cylinder 104 is disposed in the second centrifugation chamber 112 in such a posture that the axial direction thereof faces the vertical direction. The centrifugation inner cylinder 104 has a second inlet 124 on the upper end side. The second inlet 124 opens in the vicinity of the inner peripheral surface of the annularly formed upper wall portion 120 . This allows the second inlet 124 to introduce an air flow into the centrifugation inner cylinder 104 along the curve of the inner peripheral surface of the upper wall portion 120 . When the airflow enters the centrifugal inner cylinder 104 through the second inlet 124, a swirling airflow is formed that proceeds downward (in the direction toward the centrifugal reduced-diameter portion 122). As a result, relatively small dust contained in the air introduced into the centrifugal separation inner cylinder 104 is centrifuged (second centrifugal separation). Dust separated by the second centrifugal separation is discharged from the lower end side of each centrifugal separation inner cylinder 104 toward the dust collection container 50 . The second centrifugal separation chamber 112 communicates with an inner dust collection chamber 74 formed within the dust collection container 50 . Therefore, the dust discharged from each centrifugal separation inner cylinder 104 falls toward the inner dust collection chamber 74 and accumulates. After the dust is removed from the air introduced into the centrifugal inner cylinder 104 in the second centrifugal separation, the air becomes an ascending air current from the lower side to the upper side of the centrifugal inner cylinder 104, and upward (downstream) side).

The lid portion 106 is attached so as to cover the upper end side of the centrifugal separation outer cylinder 102 . The lid portion 106 has a lid plate portion 130 and an insertion portion 132 . The cover plate portion 130 is a plate-like portion formed in a substantially circular shape in plan view. The cover plate portion 130 has a substantially disk-shaped blocking portion 134 and an upright portion 136 erected from the blocking portion 134 at the outer edge of the blocking portion 134 . The closing part 134 is provided with centrifugation exhaust ports 138 at positions corresponding to the plural centrifugation inner cylinders 104 . The standing portion 136 protrudes toward both the surface side and the back surface side of the closing portion 134 . Also, the insertion portion 132 is a cylindrical portion provided corresponding to each centrifugal separation exhaust port 138 provided in the closing portion 134 . The insertion portion 132 protrudes toward the back side (upstream side) of the closing portion 134 . The inserting portion 132 is inserted into each centrifuge inner cylinder 104 . The insertion portion 132 also protrudes toward the front side (downstream side) of the blocking portion 134, and may protrude to a height higher than the blocking portion 134. It stands out with its height. Between the closing portion 134 and the insertion portion 132 , a recess 132 a lower than the height of the insertion portion 132 is provided around the insertion portion 132 . As a result, dust adhering to the filter 70 naturally drops onto the blocking portion 134, and even if it is moved by the airflow, it can be accumulated in the recess 132a.

The support portion 108 supports the filter support portion 80 from the upstream side (lower side in the illustrated state). The support portion 108 is a rib that supports the filter support portion 80 and reinforces the filter support portion 80 . The support portion 108 has a central support rib 140 and outer support ribs 142 .

The central support rib 140 is a rib protruding toward the front side (downstream side) from the substantially central portion in the radial direction of the closing portion 134 of the cover plate portion 130 . The center support rib 140 can also be used as a knob for removing the centrifugal separation unit 100 from the dust container 50 . Further, the outer support rib 142 is a rib provided radially outside of the closed portion 134 relative to the central support rib 140 . The outer support ribs 142 , like the central support ribs 140 , protrude toward the front side (downstream side) of the closing portion 134 .

The filter 70 is for trapping dust contained in the air discharged from the centrifugal separation outlet 138 of the centrifugal separation section 100 . The filter 70 is made of, for example, non-woven fabric. The filter 70 is provided downstream of the centrifugal separation unit 100 in the air blowing direction. Specifically, the filter 70 is placed on the lid portion 106 provided on the upper end side of the centrifugal separation portion 100 via the filter support portion 80 .

As shown in FIG. 6 , the filter support portion 80 is a member for supporting the filter 70 downstream of the centrifugal separation exhaust port 138 of the centrifugal separation portion 100 in the air flow direction (upper side in the illustrated example). The filter support portion 80 has a support frame 150 , an exhaust port facing portion 152 and a support opening 154 .

The support frame 150 supports the filter 70 from the upstream side in the flow direction of the air (exhaust air) while separating the filter 70 from the centrifugal exhaust port 138 . The support frame 150 includes an outer edge portion 156 formed in an annular shape, a radial connecting portion 158 connecting the outer edge portion 156 and the exhaust port facing portions 152, and a peripheral portion connecting the circumferentially adjacent exhaust port facing portions 152, 152. and a directional connector 160 .

The outer edge portion 156 is a portion forming the outer edge of the support frame 150 . The outer diameter of the outer edge portion 156 is the same as the inner diameter of the standing portion 136 forming the outer edge of the cover plate portion 130 in the cover portion 106 . Therefore, when the support frame 150 is fitted in the region surrounded by the standing portion 136 in the lid portion 106 , the outer edge portion 156 stands at a position adjacent to the standing portion 136 radially inward. . Further, the outer edge portion 156 is provided with a groove 156a formed over substantially the entire circumference. The groove 156a is open upward.

The radial connecting portions 158 are provided according to the number of the exhaust port facing portions 152 (five in this embodiment). The radial connecting portions 158 are radially provided in a plan view of the support frame 150 and connect the exhaust port facing portion 152 and the outer edge portion 156 . Moreover, the circumferential connecting portion 160 linearly connects the exhaust port facing portions 152 , 152 . In this embodiment, since there are five exhaust port facing portions 152, the circumferential connecting portion 160 is provided in a substantially pentagonal shape.

The exhaust port facing portion 152 is provided at a position facing the centrifugal exhaust port 138 while being separated from the centrifugal exhaust port 138 downstream in the air discharge direction. The outlet facing portion 152 is formed to have substantially the same size and shape as the opening region of the centrifugal separation outlet 138 .

The support openings 154 are one or more openings provided to exhaust air exhausted from each of the centrifugal outlets 138 downstream. In this embodiment, the support frame 150 can reduce the outflow resistance and pressure loss of the air discharged from the plurality of centrifugal separation outlets 138, and can use the filter 70 as a whole, thereby improving the collection effect. In order to do so, the support frame 150 is open except for the portion where the outer edge portion 156, the radial connecting portion 158, the circumferential connecting portion 160, and the exhaust port facing portion 152 are provided. In this embodiment, this open portion serves as the support opening 154 . In other words, the support opening 154 is configured by a plurality of openings surrounded by the outer edge 156 , the radial connecting portion 158 , the circumferential connecting portion 160 and the outlet facing portion 152 .

The cover portion 90 is a cover that is attached to the downstream side (the upper side in the illustrated example) of the filter support portion 80 described above in the air flow direction. The cover part 90 is a member formed in a substantially cylindrical shape, and has a dust collection part discharge port 170 on the downstream side (the upper side in the illustrated example). The cover portion 90 has L-shaped grooves (an axial groove and a circumferential groove) on the inner peripheral surface, and radially extending projections on the outer surface of the dust collection container 50 . When the cover portion 90 is attached to the dust collection container 50, a projection is inserted into the inlet of the axial groove, and the cover portion 90 covers the dust collection container 50 so that the projection slides to the end of the axial groove. move to Then, the cover portion 90 is rotated in the circumferential direction so that the projection slides from the end of the axial groove to the end of the circumferential groove continuous to the axial groove. The cover part 90 is fixed to the dust container 50 by such an operation. Here, a sealing member may be arranged between the cover portion 90 and the dust container 50 . This seal member can be configured to be annularly arranged at the upper end of the dust container 50 . Thereby, the airtightness between the dust container 50 and the cover portion 90 can be ensured.

<<Third modification>>
Here, as disclosed in Japanese Unexamined Patent Application Publication No. 2014-8302, a vacuum cleaner equipped with a dust collecting device detachable from a vacuum cleaner body is known. For example, the vacuum cleaner disclosed in Japanese Patent Application Laid-Open No. 2014-8302 is detachable from the cleaner body, and protrudes toward the cleaner body and has an engagement hole formed in the cleaner body. It is provided with a dust container having a protrusion that is inserted into the dust container. In this electric vacuum cleaner, the mounting direction is the direction in which the projecting portion protrudes when the dust containing portion is mounted on the cleaner main body. Further, the dust containing portion is designed so that the dust containing portion can be removed from the cleaner body when the extraction direction from the cleaner body is greater than 90 degrees with respect to the mounting direction. The positional relationship with the machine body is set. As described above, the method for fixing the dust collector to the cleaner body and the method for releasing the fixation of the dust collector to the cleaner body are described in the canister type cleaner having the detachable dust collector. Various technologies have been provided in the above, etc., and the dust collecting device is fixed to the cleaner body so that airtightness between the cleaner body and the dust collecting device is maintained.

However, in many electric vacuum cleaners, such as the canister-type vacuum cleaner disclosed in Japanese Unexamined Patent Application Publication No. 2014-8302, the entire bottom portion of the dust collector is configured to be supported by the main body of the vacuum cleaner.
