As shown in FIG. 6, the first dust collection section 17 includes a first filter section 21, an inflow section case 22, a guide section 23, a discharge section 24, a conical section 25, a partition section 26, and a first dust collection container 17B. ing. The first filter section 21, the inflow section case 22, the guide section 23, the discharge section 24, the conical section 25, and the partition section 26 constitute the first dust separation section 17A.

As shown in FIGS. 6 to 8, an inlet 27 is formed in the inlet case 22. As shown in FIGS. The side surface of the inlet case 22 consists of an arcuate surface 28 and a straight surface 29. As shown in FIG. 7, the inlet case 22 has a D-shape when viewed from above. The inlet 27 is arranged on the straight surface 29. The inflow port 27 is an opening through which dust-containing air flows into the first dust collecting section 17 . Further, as shown in FIG. 6, the upper end of the inlet case 22 is open parallel to the upper surface of the guide section 23. As shown in FIG.

At the upper end of the opposite side of the straight surface 29 of the inlet case 22 across the pleated first filter body 31 disposed inside the first filter section 21, there is a first dust part 17. A first upper end surface locking portion 17A1 that locks the separating portion 17A with the main body portion locking portion 162 of the main body portion 16 is provided. As shown in FIG. 8, the first upper end surface locking portion 17A1 is formed with a protruding portion 17A1a that protrudes upward in a direction opposite to the first dust collecting container 17B. Further, the protruding portion 17A1a is formed with an inclined portion 17A1b that is inclined downward toward the center of the first dust collecting portion 17 having a cylindrical shape. Furthermore, the protrusion 17A1a is urged upward by a spring 17A1c.

The first filter section 21 is removably housed in the upper part of the inflow section case 22. The upper surface of the first filter section 21 is a plane parallel to the upper surface of the guide section 23 . As shown in FIG. 7, the first filter section 21 includes a frame 30, a first filter main body 31, and a first packing 32. The frame body 30 has a D-shape similar to the inlet case 22 when viewed from above. The first packing 32 is arranged on the outer periphery of the upper surface of the frame 30. The first packing 32 is for bringing the cleaner body 11 and the first dust collecting section 17 into close contact with each other.

The guide section 23 is a member for guiding the dust-containing air that has flowed in from the inlet 27 of the inflow section case 22 to the conical section 25 . The guide section 23 includes a guide plate 33, a top surface section 34, and a second packing 35. The conical portion 25 is a member that becomes a side wall of the separation chamber 36. The separation chamber 36 is an example of a swirling chamber for swirling dust-containing air and centrifugally separating dust from the dust-containing air.

The main portion of the conical portion 25 has an inverted conical shape. The conical portion 25 has a cylindrical conical shape as a whole. In the first embodiment, the separation chamber 36 is formed inside this conical portion 25 .

The guide plate 33 of the guide section 23 is a member that guides the dust-containing air that has flowed in from the inlet 27 to the separation chamber 36 . The top surface portion 34 becomes the top surface of the separation chamber 36 when the first dust collection section 17 is properly assembled. The second packing 35 is arranged on the outer periphery of the upper surface of the top surface portion 34. When the second packing 35 and the first dust collecting section 17 are properly assembled, they are in close contact with the inner wall of the inflow section case 22. The top surface portion 34 and the second packing 35 prevent the dust-containing air in the separation chamber 36 from leaking.

The conical part 25 is arranged below the guide part 23 in a state where the first dust collecting part 17 is properly assembled. A first opening 37 is formed in the side wall of the conical portion 25 . A second opening 38 is formed at the bottom of the conical portion 25 . The bottom of the conical portion 25 corresponds to the apex portion of an inverted conical shape. The first opening 37 and the second opening 38 are openings for discharging dust centrifuged from the dust-containing air to the outside of the separation chamber 36.

The discharge section 24 is arranged inside the conical section 25 when the first dust collection section 17 is properly assembled. The discharge portion 24 has a shape that is a combination of a cylinder and a cone. A plurality of fine holes are formed in the discharge part 24.

The first dust collecting container 17B is a container with a bottom and an open top end, and has a first peripheral wall portion 17B1 as a side surface and a first lower end surface portion 17B2 as a bottom surface. Further, the first dust collecting container 17B has a first opening 17B0 formed at the upper end. The first dust collecting section 17 is longer in the height direction, that is, in the direction perpendicular to the circumferential direction, than in the circumferential direction. In other words, the first dust collecting section 17 has a longitudinal axis in a direction perpendicular to the circumferential direction. The first dust collecting container 17B is arranged outside the conical part 25 in a state where the first dust collecting part 17 is properly assembled. Further, on the first lower end surface portion 18B2, which is the outer bottom surface of the first dust collecting container 17B, a convex-shaped vacuum cleaner side first locking portion (first convex portion) 111b (FIG. 4 A concave first lower end surface locking portion (first recess) 17B2a is formed to be locked with the first lower end surface locking portion 17B2a.

In this way, the first upper end surface locking section 17A1 and the first lower end surface locking section 17B2a of the first dust collecting section 17 are arranged on opposite sides of the first dust collecting section 17. Furthermore, the first upper end surface locking portion 17A1 is exposed to the outside of the first dust collecting portion 17, that is, to the user side. Therefore, as will be described later, it is easy for the user to operate the first upper end surface locking portion 17A1, and it is convenient to use.

In addition, the vacuum cleaner side first locking part (first convex part) 111b formed on the suction cylinder part 111 has a convex shape that projects outward from the outer shell of the suction cylinder part 111, so that dust-containing air can pass through the inside. The vacuum cleaner side first locking part 111b can be configured so as not to protrude into the inside of the suction cylinder part 111 passing through, and a decrease in pressure loss of the suction cylinder part 111 can be prevented.

A dust collection chamber is formed inside the first dust collection container 17B, which is a space for collecting dust centrifugally separated from the dust-containing air in the separation chamber 36. The dust collection chamber in the first embodiment is formed outside the conical portion 25. The partition part 26 is arranged inside the first dust collecting container 17B and outside the conical part 25. The partition wall portion 26 has a cylindrical shape. As shown in FIG. 8, the dust collection chamber of the first embodiment is divided into two parts, a first dust collection chamber 39 and a second dust collection chamber 40, by a partition wall 26.

The first dust collection chamber 39 is arranged outside the second dust collection chamber 40. That is, the second dust collection chamber 40 is arranged inside the first dust collection chamber 39. The first dust collection chamber 39 communicates with the separation chamber 36 via the first opening 37 . The second dust collection chamber 40 communicates with the separation chamber 36 via the second opening 38 .

Next, the operation of separating dust from dust-containing air will be explained.
When the vacuum cleaner 10 is removed from the support device 100 as shown in FIG. Power supply from the battery 16B to the electric blower 16A is started. As a result, when the electric blower 16A is driven, negative pressure is generated in the suction section (not shown) of the electric blower 16A, and the pressure is generated through the first dust collecting section 17, the suction cylinder section 111, the pipe body 12, and the cleaning tool 13. , a negative pressure is generated at the suction port of the cleaning tool 13. As a result, from the surface to be cleaned such as the floor, via the cleaning tool 13, the pipe body 12, the suction cylinder part 111, and the inlet 27 formed in the first dust separation part 17A of the first dust collecting part 17, Dust-containing air flows into the first dust collecting section 17 . The dust-containing air that has passed through the inlet 27 flows into the separation chamber 36 . The dust-containing air flows into the separation chamber 36 along the inner surface of the conical portion 25, that is, along the side wall forming the separation chamber 36.

The air flowing into the separation chamber 36 circulates along the side wall forming the separation chamber 36 and forms a swirling airflow within the separation chamber 36 . The swirling airflow flows downward while forming a forced vortex region near the central axis and a free vortex region outside of the forced vortex region. Centrifugal force acts on the dust contained in this swirling airflow. For example, relatively bulky waste α such as textile waste and hair is pushed outward by the centrifugal force that acts. When the dust α reaches the height of the first opening 37, it passes through the first opening 37. The dust α that has passed through the first opening 37 is sent to the first dust collection chamber 39 and collected therein.

The dust not sent to the first dust collection chamber 39 rides on the airflow in the separation chamber 36 and moves downward while swirling. Relatively small-volume dust β such as sand and dust passes through the second opening 38, falls into the second dust collection chamber 40, and is collected. The first dust collecting container 17B collects dust in this manner.

As mentioned above, the conical portion 25 forms a side wall of the separation chamber 36 of the swirling chamber. Further, the partition wall portion 26 forms a side wall of the dust collection chamber. The separation chamber 36, the first dust collection chamber 19, and the second dust collection chamber 40 are formed by combining the conical portion 25 and the partition wall portion 26 with the first dust collection container 17B. The conical portion 25 and the partition wall portion 26 in the first embodiment are an example of a cylindrical inner cylinder member that forms a dust collection chamber and a swirling chamber.

Note that the structure of the inner cylinder member according to the present disclosure is not limited to the conical portion 25 and the partition wall portion 26 shown in the first embodiment. For example, the swirling chamber and the dust collection chamber may be an integrated space. The dust collection chamber according to the present disclosure does not need to be divided into the first dust collection chamber 39 and the second dust collection chamber 40. Further, the swirling chamber may be formed outside the inner cylinder member.

The discharge part 24, the conical part 25, and the first dust collecting container 17B all have circular cross sections perpendicular to their respective central axes. In the first embodiment, the central axes of the discharge section 24, the conical section 25, and the first dust collecting container 17B are arranged to be parallel to each other. Furthermore, the central axes of the discharge portion 24 and the conical portion 25 are aligned. The center axis of the first dust collecting container 17B is offset from the center axis of the conical portion 25.

Note that the terms longitudinal axis and central axis are used in this disclosure. The central axis in the present disclosure may also include the center axis in the width direction or the center axis in the depth direction. That is, the central axis is also the longitudinal axis located at the center in the width direction or the center in the depth direction. Further, for example, the external shapes of the cross sections perpendicular to the central axis of the discharge part 24, the conical part 25, and the first dust collecting container 17B are not necessarily limited to a perfect circle; There may be some unevenness. A central axis in this disclosure refers to an axis at the approximate center of an object having a longitudinal axis.

Further, as shown in FIG. 6, the first dust collecting container 17B is provided with a first rotary engagement portion 52. As an example, the first rotary engagement part 52 is provided in the first opening 17B0, which is the upper end of the inner wall of the first dust collecting container 17B. The conical portion 25 and the first dust collecting container 17B are detachably combined via the first rotary engagement portion 52. The first dust collecting container 17B is attached and detached by being rotated along its circumferential direction.

Even when the first dust collection container 17B is removed from the cyclone separator, the seal member 41 remains attached to the partition wall 26.

The seal member 41 is made of, for example, soft resin. The soft resin sealing member 41 is formed integrally with the partition wall portion 26 by, for example, two-color molding. The seal member 41, which is integral with the partition wall 26, is fixed to the partition wall 26 more reliably and firmly. Note that the seal member 41 may be formed separately from the partition wall 26 and then fixed to the partition wall 26. Further, the material of the seal member 41 is not limited to soft resin, and may be, for example, rubber.

The partition wall portion 26, which is an example of an inner cylinder member, and the first dust collection container 17B, which is an example of a dust collection portion, are in close contact with each other through the seal member 41. The seal member 41 is a member for ensuring airtightness of the swirling chamber and the dust collection chamber. The sealing member 41 contacts the inner bottom surface of the first dust collecting container 17B when the first dust collecting container 17B is attached to the conical portion 25, which is an example of an inner cylinder member.

Then, as the rotation progresses, the protrusion 18A1a moves to sink toward the inside of the second dust separation section 18A against the elastic force of the spring 18A1c (not shown). When the rotation of the second dust collecting part 18 is completed, the protruding part 18A1a moves to enter the recess of the main body locking part 162 due to the elastic force of the spring 18A1c, and the second dust collecting part 18 moves to the main body. 16 and the tube body 12.

In the state in which the second dust collecting section 18 is attached to the main body section 16 and the tube section 12, as shown in FIGS. In some cases, the second peripheral wall 18B1 of the second dust collecting container 18B forms a recessed wall 18B1a at least in a portion facing the suction cylinder 111 or the pipe body 12, and the second peripheral wall 18B1 of the second dust collecting container 18B forms a recessed wall 18B1a at least in a portion facing the suction cylinder 111 or the pipe body 12, and the second dust collecting container The tip of the first locking part (first convex part) 111b on the cleaner side, which is the part that protrudes to the 18B side, or the cleaning part, which is the part that protrudes from the outer shell of the tube body 12 to the second dust collection container 18B side. It is arranged at a position spaced apart from the tip of the machine-side second locking part (second convex part) 122. That is, at least the second peripheral wall portion 18B1 of the portion facing the suction cylinder portion 111 or the pipe body 12 is located at a position that is spaced apart from the outer shell of the suction cylinder portion 111a toward the second separation portion 18 side by a distance larger than the h1 dimension, or , is arranged at a position spaced apart from the outer shell of the tube body 12 toward the second separating portion 18 by a distance larger than the h2 dimension. Therefore, when the second dust collecting part is attached to the main body mounting part and the pipe body, it is possible to prevent the second peripheral wall part of the second dust collecting container from interfering with the protruding part of the suction cylinder part or the pipe part.

Next, the operation when removing the second dust collecting section 18 from the main body section 16 and the pipe section 12 will be described. The outer side surface of the second upper end surface locking portion 18A1 is moved downward against the elastic force of the spring 18A1c (not shown), and the protruding portion 18A1a (not shown) is removed from the recess of the main body portion locking portion 162.
