Description

  The present invention relates to a cyclonic vacuum cleaner that centrifuges dust contained in the air by swirling the sucked air, and more particularly to a cyclone dust collector that is detachable from the main body of the vacuum cleaner and removes dust sucked together with air. It is related with the cyclone type vacuum cleaner provided with.

  Conventionally, various vacuum cleaners equipped with a cyclone dust collector have been proposed. The cyclone dust collector is a device that centrifugally separates dust in the air and collects the dust in a dust cup by rotating the air introduced inside at high speed. Since the exhaust air does not pass through the removed garbage, there is an advantage that the dust collecting power is maintained regardless of the accumulation of the dust and it is difficult to emit the smell of the dust in the exhaust. Fine dust that is not centrifuged is removed by a mesh-like filter provided on the peripheral surface of the exhaust pipe when it is discharged together with air from the exhaust pipe provided in the center of the cyclone dust collector. The air after the dust is removed is discharged from the exhaust tube to the outside.

  The present applicant has already automatically cleaned the filter that covers the exhaust stack in a vacuum cleaner that houses the cyclone dust collector in the main body of the vacuum cleaner, and controls the leakage of dust scraped off from the filter to the outside. Have proposed improving hygiene (Patent Document 1). According to this proposal, the cyclone main body of the cyclone dust collector is interlocked with the cleaning tool that cleans the filter by sliding with the filter coated on the surface of the exhaust pipe, and the attachment / detachment operation of the cyclone dust collector with respect to the cleaner main body, There is a sliding means for sliding the cleaning tool and the filter. The sliding means is connected to the cleaning tool via a connecting rod, and is supported by a positioning portion provided on the cleaner body side, and a support portion in the direction of taking out the cyclone dust collector from the cleaner body. And a second urging means for urging the housing fixed to the fixing plate.

  In addition, a cyclone dust collecting type vacuum cleaner has been proposed that has high dust separation efficiency and can effectively prevent the separated dust from adhering to the exhaust pipe (Patent Document 2). This cyclone dust collection type vacuum cleaner is a high-speed swirling airflow that flows from the inlet to the separation chamber of the cyclone dust collector, and the swirling airflow is the boundary between the separation chamber and the accumulation chamber. It is made the structure which descend | falls through the outer side of the shielding member arrange | positioned in this, and flows in into a collection chamber. The downward swirling airflow turns into an upward swirling airflow near the bottom surface of the accumulation chamber, and dust in the airflow is separated when the swirling airflow changes direction by colliding with a separation blade extending from the shielding member toward the bottom surface of the accumulation chamber. . Dust is separated when the upward swirling airflow passes over a loop-shaped barrier provided at the edge of the shielding member, and when it passes over ribs formed at predetermined intervals so as to block the swirling airflow on the outer periphery of the shielding member.

JP 2004-249010 A (paragraphs [0073] to [0075], FIG. 1) JP 2003-88485 A (paragraphs [0044] to [0061], FIG. 4)

  The cyclone dust collector is located in the main body of the vacuum cleaner in order to align the position of the inflow part and the exhaust part provided in the main body of the vacuum cleaner or to ensure the integrity of the main body of the vacuum cleaner that vibrates. It is fixed in a positioned state. Considering the design of the vacuum cleaner and the overall function and handling of the vacuum cleaner, the cyclone dust collector is housed in the vacuum cleaner body with a part of its outer surface exposed to the outside, giving it an integrated appearance with the vacuum cleaner body. There are many cases. When the cyclone dust collector is attached to the cleaner body, the flow path on the cyclone dust collector side is aligned with the inflow portion and the exhaust portion of the cleaner body. Therefore, on the surface, the external appearance of the cyclone dust collector is designed so as not to have a large step with respect to the external appearance of the cleaner body.

  On the other hand, when dust collected in the cyclone dust collector has accumulated, it is necessary to throw away the dust in the dust cup into a trash box or the like. A cyclone dust collector generally includes a dust cup into which a cyclone flow flows in and can collect dust contained in the flow, a lid portion that can be attached to the dust cup and that can close an opening portion of the dust cup, and the lid portion. And a cup lid assembly having a filter part that is assembled on the inner side and that filters the cyclone flow and exhausts the filtered flow. In a state where the cyclone dust collector is housed in the main body of the vacuum cleaner, the dust cup is disposed inside the main body of the vacuum cleaner, so that only the dust cup cannot be detached from the main body of the cyclone vacuum cleaner. In order to remove the dust cup, it is necessary to first remove the cyclone dust collector from the cleaner body, and in that state, separate the cyclone dust collector into a cup lid assembly and a dust cup. The same operation is required when cleaning the filter.

  Although the cyclone dust collector taken out from the main body of the vacuum cleaner has been reduced in size, the cyclone dust collector is large enough to be handled with one hand even for adults as well as women, elderly people and children. Further, if the dust cup and the cup lid assembly are not fitted without a gap, the cyclone flow may leak outside through the gap. Therefore, a lock means for locking the relative movement between the dust cup and the cup lid assembly is provided so that the dust cup and the cup lid assembly are not easily separated. The dust cup is usually formed in a cylindrical shape or a shape close to that corresponding to the cyclone flow, so that the relative movement between the dust cup and the cup lid assembly is changed between the cylindrical circumferential direction and the axial direction. Separately, the structure and arrangement of the locking means are determined so as to prevent each movement. Therefore, the locking means usually takes the form of clamps provided at a plurality of locations around the cup lid assembly.

  To separate the dust cup from the cup lid assembly, it is necessary to release these multiple clamps at the same time so that the cup lid assembly is free from the dust cup both in the circumferential direction and in the axial direction. However, it takes time to release each clamp sequentially, and improvements are required in terms of workability and convenience.

  Therefore, in the cyclone dust collector, there is a problem to be solved in that the degree of freedom in the circumferential direction between the two is restricted in a state where the dust cup and the cup lid assembly are assembled, and the clamping operation is limited only to the axial direction between the two. is there.

  The object of the present invention is to limit the clamping operation only in the axial direction between the two, reduce the operation required for mounting and releasing the dust cup and the cup lid assembly, and improve the workability and convenience of the cyclone dust collector. It is to provide a cyclone type vacuum cleaner that is easy to handle even for adults as well as women, elderly people and children.

To solve the above problems, a cyclone type vacuum cleaner according to the present invention, the integrable dirt-dust contained in the flow enters the cyclone flow is attachable to the dust cup and the dust cup a cup lid assembly having a filter portion of the cyclone flow assembled inner side to exhaust the filtered flow filtration of the lid closable opening and the lid of the cup lid assembly wherein has a flow restriction blade attached to a lower portion of the filter unit and reaches the bottom of the dust cup, the bottom of the dust cup, a lower end portion engaged with said cup lid assembly of said flow regulating vane is the rib to prevent the relative rotation about the axis of the dust cup in the dust cup is formed, the dust cup, the cup lid assembly Serial is provided with releasable single locking means for preventing the dust cup for withdrawing axially, it consists further in the cup lid assembly is provided with a handle for gripping.

According to this cyclone type vacuum cleaner, when the cup lid assembly is mounted on the dust cup and the locking means is operating, the rib portion as the relative rotation preventing means is already provided between the dust cup and the cup lid assembly. Is engaged with the lower end of the flow restricting blade attached to the lower portion of the filter portion in the cup lid assembly , so that the cup lid assembly is prevented from rotating relative to the dust cup, and the locking means is The axial removal of the cup lid assembly from the dust cup is prevented. Therefore, in a state where the locking means is operating, the cup lid assembly and the dust cup are integrated with each other, and the cup lid assembly and the dust cup are not separated. When separating dust cups and cup lid assemblies that make up a cyclone dust collector, such as when dust collection has progressed and it is necessary to dispose of dust, release the single locking means to release the cup lid assembly and dust. The restraint in the axial direction with the cup is released, and the axial movement, that is, extraction becomes possible. When the cup lid assembly is removed from the dust cup, the state where the lower end of the flow regulating blade of the cup lid assembly is prevented from being relatively rotated by the rib portion is released and the cup lid assembly is removed from the dust cup. It can be completely separated. When the cup lid assembly is attached to and removed from the dust cup, the locking means can be operated while gripping the handle. That is, by holding the handle provided on the cup lid assembly, and by pressing the dust cup on the table or floor via the locking means, the cup lid assembly is attached to or removed from the dust cup. Can do. The handle for gripping can be provided so as to be able to jump out of the cup lid assembly.

In this cyclone type vacuum cleaner, the flow restricting blade attached to the lower part of the filter part of the cup lid assembly reaches the bottom of the dust cup, restricts the cyclone flow in the dust cup, weakens the flow velocity, and collects. Prevents dust from rising up.

In this cyclonic vacuum cleaner, the locking means may be displaceable between a locked position where the cup lid assembly is locked in the dust cup and an unlocked position where the cup lid assembly is unlocked. it can. By displacing and operating the locking means between the locked position and the unlocked position, the cup lid assembly can be locked or unlocked with respect to the dust cup. In this case, locking means, for the dust cup includes a clamp which is provided to be displaceable between a locked position and an unlocked position by rotation, elastic means toward the clamp in a locked position Can be energized. By providing the clamp biased by the elastic means, the cup lid assembly is unlocked with respect to the dust cup by performing an operation of displacing the clamp to the unlocked position against the biasing force of the elastic means. be able to. When the operation is released, the clamp is automatically displaced to the locked position by the biasing force of the elastic means, and the cup lid assembly can be shifted to the locked state with respect to the dust cup.

  In the cyclone type vacuum cleaner provided with this clamp, the cup lid assembly may be provided so as to protrude outward from the lid portion and have a claw portion that can be engaged with the clamp. By providing the cup lid assembly with a claw portion that engages with the clamp, the influence on the fitting of the cup lid assembly to the dust cup is eliminated, and the claw portion becomes a target as a counterpart with which the clamp is engaged, The mounting position of the cup lid assembly on the dust cup can be uniquely determined.

Since the cyclone type vacuum cleaner according to the present invention is configured as described above, when the rib portion formed on the bottom portion of the dust cup and the lower end portion of the flow regulating blade of the cup lid assembly are engaged. The relative rotation of the cup lid assembly around the axis of the dust cup is prevented, and the cup lid assembly does not come off. In addition, when separating the dust cup and cup lid assembly that make up the cyclone dust collector, the axial restraint between the cup lid assembly and the dust cup can be released with a small operation of releasing a single locking means. Axial movement becomes possible. When the cup lid assembly is axially displaced from the dust cup, the rib portion and the lower end portion of the flow regulating blade of the cup lid assembly are automatically disengaged to completely separate the cup lid assembly from the dust cup. Can do. Therefore, the locking means that needs to be operated when attaching and releasing the dust cup and the cup lid assembly is limited to one locking means only in the axial direction between them, improving the workability and convenience of the cyclone dust collector, A cyclone type vacuum cleaner that is easy to handle even for adults as well as women, elderly people, and children can be obtained.

  Hereinafter, an embodiment of a cyclonic vacuum cleaner according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is an external view showing an embodiment of a cyclonic cleaner according to the present invention, and FIG. 2 is a perspective view showing an internal structure of the cyclone cleaner shown in FIG. 1 with a case and a cover removed.

  A cyclonic cleaner 1 shown in FIG. 1 has a cleaner body 2, a connection hose 3, and a suction head 4. The cleaner body 2 includes a case 5, a wheel 6, and a cover 7 that covers an upper main part of the cleaner body 2 housed in the case 5. The connection hose 3 constitutes a supply path for supplying the air sucked from the suction head 4 to the cleaner body 2. The connection hose 3 is provided with an operation / control unit 8 for operating the position and direction of the suction head 4 and manually controlling the scratching function of the cleaner provided in the cleaner body 2. The suction head 4 can suck dust together with air through an air suction port (not shown) by operation of an electric blower described later.

  As shown in FIG. 2, the vacuum cleaner body 2 includes an electric blower 9, a cyclone dust collector 10, and a rear filter 60. The electric blower 9 sucks air from the suction head 4 through the connection hose 3 and the cyclone dust collector 10. The cyclone dust collector 10 is provided so as to be detachable from the cleaner body 2, and is a dust collector that turns air sucked by the electric blower 9 and centrifuges dust contained in the air, as will be described later. .

  In the above configuration, when the electric blower 9 housed in the cleaner body 2 is driven, air is sucked from the air suction port of the suction head 4 and sent to the cyclone dust collector 10 via the connection hose 3. In the cyclone dust collector 10, dust contained in the air is centrifuged and collected in the dust cup 12. On the other hand, the air from which the dust has been removed is then discharged out of the machine through an exhaust tube 15 and a filter unit 16 of the cyclone dust collector 10 through a discharge port (not shown) provided in the cleaner body 2. .

  3 is a perspective view showing a state in which a handle provided in the cup lid assembly is housed in the cyclone dust collector, and FIG. 4 is a handle provided in the cup lid assembly in the cyclone dust collector shown in FIG. FIG. 5 is a longitudinal sectional view of the cyclone dust collector shown in FIG. 3, FIG. 6 is a perspective view showing the main part of the cup lid assembly taken out from the cyclone dust collector shown in FIG. FIG. 4 is a perspective view showing the dust collecting cup after the cup lid assembly is taken out from the cyclone dust collector shown in FIG. 3.

  For convenience of explanation below, the side to which the connection hose 3 (see FIG. 1) is connected in the vacuum cleaner is referred to as the front, and the opposite side is referred to as the rear. Moreover, the taking-out direction from the cleaner main body 2 of the cyclone dust collector 10 is called upper direction, and the accommodation direction to the cleaner main body 2 of the cyclone dust collector 10 is called downward.

  The cyclone dust collector 10 includes a cup lid assembly 11 as a dust collector body and a dust cup 12 (dust collector). That is, in the cyclone dust collector 10, the portion excluding the dust cup 12 constitutes the cup lid assembly 11.

The dust cup 12 is a substantially cylindrical container for collecting dust centrifuged by the high-speed swirling of sucked air. In particular, as shown in FIGS. A cup lid assembly 11 is detachably connected to the. Further, in order to introduce the air supplied from the suction head 4 shown in FIG. 1 through the connection hose 3 into the dust collector, an air inlet 12a is formed in front of and above the side surface of the dust cup 12. As shown in FIG. 5, an annular cyclone dust collection chamber 12 b in which air introduced through the air inlet 12 a is swirled at a high speed is formed above the dust cup 12.

As shown in FIG. 5 or 6, the cup lid assembly 11 includes a lid portion having a lid body 13 as an upper lid of the dust cup 12 and a lid bottom plate 14 as a back lid , an exhaust cylinder 15, and a filter portion 16. The cleaning tool 17 and the connecting means 18 are provided. As shown in FIGS. 3 to 6, the lid body 13 includes a handle body 30. For example, by operating an operation unit 40 for engaging and disengaging the cover 7 as shown in FIG. The handle body 30 can be popped up from the lid body 13 in conjunction with the disengagement of the body 30 from the lid body 13. The pop-up state of the handle body 30 is shown in FIGS.

  The lid body 13 includes a top surface 19 and a side surface portion 20, and a joint side to the dust cup 12 is coupled to the lid bottom plate 14. The top surface 19 is formed with a smooth curved surface that minimizes the space formed between the top surface 19 and the inner surface of the cover 7, and contributes to the downsizing of the cyclonic vacuum cleaner 1. The air that has flowed into the front air inlet 12a, centrifuged the dust in the cyclone dust collector 10, and moved up the exhaust cylinder 15 is further exhausted rearward from an air outlet 21 formed behind the lid 13. The

When the cup lid assembly 11 is attached to the dust cup 12, the lid bottom plate 14 of the lid portion is fitted into the opening of the dust cup 12, thereby closing the dust cup 12 . In the fitted state, the cup lid assembly 11 does not move in the left-right and front-back directions with respect to the dust cup 12, and a ring-shaped packing 22 (see FIG. 5) disposed at the lower peripheral corner of the lid bottom plate 14 The opening of the dust cup 12 can be sealed, and the collected dust is prevented from leaking outside.

  In the cup lid assembly 11, as shown in FIGS. 5 and 6, an opening corresponding to the diameter of the exhaust cylinder 15 is formed in the substantially central portion of the lid bottom plate 14. The opening is fixed to the lid bottom plate 14 so that the opening coincides with the opening of the lid bottom plate 14. The exhaust cylinder 15 is a cylinder in which a plurality of exhaust ports for discharging air after centrifugal separation of dust in the cyclone dust collecting chamber 12b are opened on the peripheral surface, and the exhaust port is provided on the peripheral surface. The filter 16 (first filter) is covered so as to cover it. The filter 16 removes fine dust that has not been removed by the centrifugal separation in the cyclone dust collecting chamber 12b, and is formed in a mesh shape, for example.

  One end (upper end) of the exhaust cylinder 15 in the axial direction is connected to the opening of the lid bottom plate 14 as described above. Accordingly, the exhaust cylinder 15 is integrated with the lid body 13 via the lid bottom plate 14. On the other hand, the other end (lower end) of the exhaust cylinder 15 in the axial direction is connected to the suppression valve 25 via a shielding member 26 that divides the cyclone dust collection chamber 12b and the dust accumulation chamber 12c below the cyclone dust collection chamber 12b. The shielding member 26 prevents dust accumulated in the lower dust collection chamber 12c from rising to the upper cyclone dust collection chamber 12b. The suppression valve 25 has, for example, a structure of four flow regulating blades 25a that extend in the radial direction and are formed in a cross blade shape when viewed from the axial direction. The flow restricting blade 25a is for preventing dust in the dust cup 12 from rising due to high-speed swirling of air in the cyclone dust collecting chamber 12b. In this example, the suppression valve 25 and the shielding member 26 are an integrated lower assembly 28, but separately manufactured ones may be combined. The lower assembly 28 can be disposed in the dust cup 12 by attaching the lower assembly 28 to the lower portion of the exhaust cylinder 15. Further, the lower assembly 28 is detachably attached to the lower portion of the exhaust cylinder 15 by a fixing means 29 such as a bayonet or a screw, so that the exhaust cylinder 15 and the lower assembly 28 are disassembled and cleaned and washed. This improves convenience.

  With the above configuration, the air introduced into the cyclone dust collecting chamber 12b from the air inlet 12a of the cyclone dust collector 10 is swirled at a high speed in the cyclone dust collecting chamber 12b, and the filter 16 and the exhaust port on the peripheral surface of the exhaust cylinder 15 are passed through. Through the exhaust tube 15. At this time, most of the dust that has not been removed from the air in the cyclone dust collection chamber 12 b is removed by the filter 16. The air that has passed through the filter 16 and the exhaust port proceeds to the inside of the exhaust cylinder 15 toward the axial lid 13 and continues from the air exhaust port 21 through a passage in the lid 13 through the opening of the lid bottom plate 14. To the rear filter 60 (FIG. 2). Then, the air is further cleaned by the rear filter 60 (dust that has not been removed by the filter 16 is removed) and discharged from the exhaust port (not shown) of the rear filter 60 to the outside of the cyclone dust collector 10, and the vacuum cleaner main body. 1 is discharged to the outside of the cleaner body 2 through an exhaust path (not shown) in 1 and an electric blower 9 (FIG. 2).

  The cup lid assembly 11 is provided with a handle body 30 that pops up from the lid body 13 above the top surface 19 by a pop-up operation. The handle body 30 includes a grip portion 31 that extends in the front-rear direction through the center and deformed shaft portions 32 and 33 that integrally extend downward at both ends of the handle body 30. As shown in FIG. 3, the handle body 30 sinks into an accommodation recess 27 formed in the lid body 13 in conformity with the shape of the handle body 30 except for both ends when accommodated in the cup lid assembly 11. Although it is in the state, in the pop-up state, as shown in FIG. 4, the shaft portions 32 and 33 are in a state in which the lid body 13 protrudes. The handle body 30 is guided in a vertical direction with a good balance with respect to the cup lid assembly 11 by sliding and guiding the shaft portions 32 and 33 to the guide portions 34a and 34b extending from the lid bottom plate 14 of the cup lid assembly 11. Is done. In order to urge the handle body 30 in the pop-up direction from the lid body 13, an elastic body (not shown) (for example, a coil spring) is not provided between the lid body 13 and the lid bottom plate 14 in the shaft portions 32 and 33. Is intervening. A handle clamp 36 is provided in the middle of the grip portion 31 in order to keep the handle body 30 in the stored state in the lid body 13 against the urging force of the elastic body. For example, by linking the operation when removing the cover 7 from the cleaner body 2 by the operation unit 40 shown in FIG. 1 with the release operation of the handle clamp 36 via the interlocking mechanism 41, the handle body 30 can be The lid 36 is released from the clamped state by the clamp 36 and is popped up by the restoring force of the elastic body. The pop-up amount of the handle body 30 is limited by the stroke of the cleaning tool 17 described later. In this embodiment, the cover 7 can be opened from the cleaner body 2 and the handle body 30 can be automatically popped up from the lid body 13 by a one-touch operation on the operation unit 40, and the user grasps the handle body 30 that has popped out. The cup lid assembly 11 and the dust cup 12 can be lifted to improve the operability in the attaching / detaching operation of removing and attaching the cyclone dust collector 10.

  Next, the cleaning tool 17 and the connecting means 18 will be described. As shown in FIG. 5, the cleaning tool 17 cleans the filter 16 by sliding with the filter 16 on the peripheral surface of the exhaust tube 15, and slides with the filter 16 along the peripheral surface of the filter 16. A cleaning ring 50 made of a brush and a flat ring holder 51 that supports the brush are provided. The cleaning tool 17 is disposed at the lowest position where the cleaning ring 50 comes into contact with the shielding member 26 in a state where the handle body 30 is accommodated in the lid body 13.

  As shown in FIG. 6, the connecting means 18 includes a plurality of shafts 52 that connect the ring holder 51 to the handle body 30, and in conjunction with the pop-up operation from the lid body 13 of the handle body 30, the cleaning tool 17 is slid against the filter 16. The shaft 52 is accommodated in a concave groove formed on the outer periphery of the exhaust tube 15 in order to avoid the formation of unnecessary uneven portions where dust accumulates by making the outer peripheral surface of the exhaust tube 15 as smooth as possible. Thus, it is possible to slide in the groove in conjunction with the pop-up operation of the handle body 30.

  According to the above configuration, the handle body 30 moves up and down integrally with the cleaning ring 50 via the shaft 52 constituting the connecting means 18. Therefore, every time the handle body 30 performs a pop-up operation, the cleaning ring 50 moves upward via the shaft 52 and slides on the filter surface side of the filter 16 of the exhaust pipe 15. As a result, fine dust collected on the filter 16 is scraped off by the cleaning ring 50 and dropped into the cyclone dust collecting chamber 12b.

The dust cup 12 is provided with the locking means in the present invention so that the cup lid assembly 11 can be attached to and detached from the dust cup 12 and the fitting state is maintained in the attached state. FIG. 8 is an explanatory view showing the operation of the locking means used in the cyclone dust collector, and FIG. 8 (a) shows the state where the locking means places the cup lid assembly in a locked state with respect to the dust cup, FIG. 8B shows a state in which the lock means places the cup lid assembly in an unlocked state with respect to the dust cup. The locking means includes a lever-like clamp 23 that can be rotated by hand around the shaft 24, and an elastic means such as a spring 24a that biases the clamp 23 with a biasing force in the direction of arrow A in FIG. It has. As shown in FIGS. 5 and 8, the lock means is a single lock means provided in the cup lid assembly 11. In the state where the locking means occupies the locking position shown in FIG. 8A, the engaging portion 23a of the clamp 23 is a claw that extends laterally as a part from the lid bottom plate 14 beyond the side surface portion 20 by this biasing force. By pressing the portion 20a, the cup lid assembly 11 is prevented from being detached from the dust cup 12 in the axial direction, that is, in the upward direction. In the locked state, the clamp 23 prevents the cup lid assembly 11 and the dust cup 12 from rattling. When the collected dust is discarded or the filter is washed, the clamp 23 is pushed with a finger or the like to rotate against the urging force of the spring 24a to separate the locking portion 23a from the claw portion 20a. Thus, the locking means occupies the non-locking position shown in FIG. 8B, and the cup lid assembly 11 and the dust cup 12 can be separated.

The clamp 23 prevents the cup lid assembly 11 from moving in any direction with respect to the dust cup 12 in cooperation with preventing the cup lid assembly 11 from coming off in the axial direction. Relative rotation preventing means is provided for preventing relative rotation of the cup lid assembly 11 with respect to the dust cup 12 when mounted on the cup 12. In this embodiment, as shown in FIGS. 5 and 6, the relative rotation preventing means uses a suppression valve 25 having a structure of a flow restricting blade 25 a formed as a cross blade as the lower assembly 28. At the bottom of the dust cup 12, a cross-shaped groove is formed by a cross-shaped rib 57 formed by integral molding. The relative rotation prevention means is configured such that the cross-shaped flow restricting blade 25a of the suppression valve 25 is the groove. Is obtained by a structure engaging with. That is, when the cup lid assembly 11 is attached to or detached from the dust cup 12, the relative rotation prevention means is such that the lower end of the suppression valve 25 engages in the groove formed by the rib 57 or comes out. Although movement in the vertical direction is allowed, the cup lid assembly 11 has its own shaft in the dust cup 12 (the vertical axis passing through the center of the exhaust cylinder 15 and the suppression valve 25, that is, dust when attached to the dust cup 12. Relative rotation about the axis extending in the vertical direction connecting the center of the bottom of the cup 12 and the center of the opening is prevented. The locking means operates in a state where the cup lid assembly 11 is mounted in the dust cup 12, and the dust of the cup lid assembly 11 is simply controlled by restricting the cup lid assembly 11 to the dust cup 12. The lock on the cup 12 is completed.

  When the dust accumulated in the dust cup 12 of the cyclone dust collector 10 is discarded or when the filter 16 or the like is cleaned, the pop-up handle body 30 is grasped with one hand, and the cup lid assembly 11 and the dust cup 12 are held. And are removed from the vacuum cleaner body 2 completely. With the handle body 30 held, the single clamp 23 can be unlocked with the free hand. After releasing the lock by the clamp 23, the cup lid assembly 11 is pulled out from the dust cup 12 in the vertical direction, so that the flow restricting blade 25 comes out of the groove formed in the rib 57, and the cup lid assembly 11 is removed from the dust cup. 12 completely separated.

  Next, when the taken-out cyclone dust collector 10 is accommodated in the cleaner body 2 again, it can be achieved by performing the above operations in reverse. That is, the cup lid assembly 11 and the dust cup 12 are fitted with the handle body 30 popped up, the lower end of the flow restricting blade 25 is engaged with the groove formed in the rib 57, and in this state Lock with clamp 23. The cyclone dust collector 10 in which the cup lid assembly 11 and the dust cup 12 are locked is accommodated in the cleaner body 2 while the handle body 30 is gripped. Thereafter, the handle body 30 is pushed into the lid body 13 to re-engage the handle clamp 36. Finally, the cover 7 is closed with respect to the cleaner body 2 to complete a series of operations.

  In the above embodiment, the relative rotation preventing means is configured by using the flow restricting blade 25 and the rib 57, but formed on the peripheral portion of the lid 13 and the inner peripheral portion of the opening of the dust cup 12, etc. An appropriate concave-convex fitting structure that fits in the circumferential direction so as not to move relative to each other can be formed. Moreover, although the locking means is constituted by the clamp 23 and the spring 24a, any appropriate means for regulating the cup lid assembly 11 and the dust cup 12 in the vertical direction can be used instead. In addition, it is apparent that the present invention can be appropriately modified and implemented without departing from the spirit described in the claims.
