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 gas does not pass through the removed garbage, there is an advantage that the dust collection power is maintained regardless of the accumulation of the dust and it is difficult to emit the smell of dust in the exhaust gas. 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.

Further, 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 collecting type vacuum cleaner is a high-speed swirling air flow that flows into the separation chamber of the cyclone dust collecting device from the inlet into the separation chamber of the cyclone dust collecting device. 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 cleaned in a positioned state in the cleaner body in order to align the inflow portion and the exhaust portion provided in the cleaner body or to ensure the integrity of the vibrating cleaner body. It is fixed to the machine body. Considering the design of the vacuum cleaner and the function and handling of the vacuum cleaner as a whole, the cyclone dust collector is housed in the vacuum cleaner body with some of its outer surfaces exposed to the outside, and has an integrated appearance with the vacuum cleaner body. Often given. 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. In a state where the cyclone dust collector is housed in the vacuum cleaner main body, it is necessary to remove the cyclone dust collector from the vacuum cleaner main body and remove the dust cup from the cyclone dust collector in that state because the dust cup alone cannot be removed from the cyclone main body alone. The same operation is required when cleaning the filter.

  According to the above structure, the cyclone dust collector that is released from the fixed state with respect to the cleaner body can be attached to and detached from the cleaner body. It is difficult to get a clue to take out. In view of this, it has also been proposed to lift the head of the cyclone dust collector by providing a cup takeout button on the cleaner body and operating the cup takeout button. In order to take out the cyclone dust collector from the main body of the vacuum cleaner, it is necessary to hold and lift the entire head of the cyclone dust collector. Further, when the taken-out cyclone dust collector is transported to the trash box, it is necessary to move while holding the head of the cyclone dust collector.

  Therefore, when the cyclone dust collector is housed in the vacuum cleaner body, the design is kept clean and the operability is further improved when removing the cyclone dust collector from the vacuum cleaner body and when transporting it after removal. There is a problem to be solved.

  The present invention has been made in order to solve the above-described problems, and its purpose is to provide a cyclone type vacuum cleaner in which a cyclone dust collector is accommodated in a vacuum cleaner body, and a state in which the cyclone dust collector is housed in the vacuum cleaner body. It is an object of the present invention to provide a cyclonic vacuum cleaner that maintains a clean appearance and can be easily and reliably carried out when the cyclone dust collector is taken out from the main body of the vacuum cleaner and carried after being taken out.

  In order to solve the above-described problems, a cyclone type vacuum cleaner according to the present invention is a cyclone type vacuum cleaner provided with a cyclone dust collector that is detachably accommodated in a vacuum cleaner body and centrifuges dust in the sucked air. Comprises a dust cup for storing the dust, a dust collector main body that engages with the dust cup and can close an opening of the dust cup, and a handle body attached to the dust collector main body, the handle body being the dust collector main body It is made up of a pop-up available from.

  According to this cyclone type vacuum cleaner, when the handle body is not popped up, the handle body is accommodated in the dust collector main body, which contributes to an improvement in appearance and space saving around the dust collector main body. By providing the handle body so that it can be popped up from the dust collector body, the handle body that has been popped up can be gripped, the cyclone dust collector can be easily handled, and the operability is improved. For example, the cyclone dust collector can be lifted integrally and taken out from the main body of the cleaner, and the cyclone dust collector can be carried while being held. The same applies to the case where the cyclone dust collector is returned to the vacuum cleaner main body after dust processing and cleaning.

  In this cyclone type vacuum cleaner, an elastic body that urges the handle body in a pop-up direction with respect to the dust collector main body, an engagement state that stores and holds the handle body against the urge force of the elastic body against the dust collector main body, and And an engaging portion that can be switched between a released state and a released state. According to this cyclone type vacuum cleaner, in a state where the engaging portion is engaged, the handle body is stored and held against the dust collector main body against the biasing force by the elastic body, and the biasing force is stored in the handle body and the dust collector. It is internalized with the main body. In this state, the handle body is housed in the dust collector main body, and the space occupied around the cleaner due to the handle popping out can be suppressed. Further, in the released state where the engaging portion is disengaged from the engaged state, the restraint of the handle body in the pop-up direction with respect to the dust collector main body is released, so that the handle body automatically pops up from the dust collector main body by the biasing force of the elastic body.

  In the cyclonic vacuum cleaner provided with the elastic body and the engaging portion, the handle body includes a grip portion and a shaft portion that is displaced and guided in a pop-up direction with respect to the dust collector body at both ends of the grip portion. The joint portion may be disposed at an intermediate position of the grip portion, and the elastic body may be a coil spring accommodated in each of the shaft portions. Displacement guidance of the handle body in the pop-up direction with respect to the dust collector main body by the shaft portions at both ends, and by disposing the engaging portion at an intermediate position of the grip portion, the force acting on the handle body can be distributed in a balanced manner on both sides. As a result, a stable pop-up operation of the handle body is ensured. Also. By making the elastic body a coil spring accommodated in the shaft portion, the elastic body can be disposed in a space-saving manner and a stable force can be applied to the handle body.

  The cyclonic vacuum cleaner including the elastic body and the engaging portion further includes a cover that can be engaged with and disengaged from the cleaner body and covers the cleaner body, and the cover operates to engage and disengage from the cleaner body. An operating unit and an interlocking mechanism that switches the engaging unit of the cyclone dust collector between the engaged state and the released state in conjunction with the operation of the operating unit can be provided. According to this cyclone type vacuum cleaner, the external appearance of the cyclone type vacuum cleaner body can be made smooth by providing the cover that covers the vacuum cleaner body. The cover can be engaged with and disengaged from the main body of the vacuum cleaner, and the engagement portion for engaging the handle body with the dust collector main body is engaged with the operation of the operation portion for engaging and disengaging the cover from the main body of the vacuum cleaner. You can switch between unlocked states. In other words, with a single action at the operation unit that disengages and disengages the cover from the cleaner body, one-touch operation of opening the cover and automatically disengaging the handle body from the dust collector body to pop up the handle body Is obtained. When the urging force of the elastic body is used for the pop-up of the handle body, the cover can be lifted with the urging force, thereby making the handling of the cover more convenient. In addition, by placing the handle body in the storage state pressed against the elastic body, it is not necessary to secure a space for storing the handle body in a protruding state in the cover, thereby reducing the size of the entire cyclone cleaner. Can also contribute.

  In this cyclone type vacuum cleaner, the dust cup has a filter that divides a storage portion for storing dust on the exhaust side, and the handle body has a cleaning liner that slides on the filter storage portion side in conjunction with the pop-up of the handle body. Can do. When the cyclone vacuum cleaner is used for a long time, the filter that divides the storage part that collects dust on the exhaust side will clog by capturing dust that cannot be separated by centrifugation, and the suction force and dust collection capacity will be reduced . Therefore, by providing the handle body with a cleaning liner that slides on the filter housing portion side, the cleaning liner is slid along the surface of the filter housing portion in conjunction with the pop-up motion of the handle body. Thus, the dust trapped by the filter is scraped off. Thereby, when the handle body is in a pop-up operation, the pop-up operation is used for the cleaning operation, the filter can be automatically cleaned, and the convenience of the cyclonic vacuum cleaner is improved. The dust scraped off from the filter falls to the storage portion side and does not leak to the outside, so that hygiene is also improved.

  In a cyclone vacuum cleaner equipped with a cleaning liner for cleaning a filter, the dust collector main body has an exhaust pipe that is stretched in such a manner that a storage portion for collecting dust is formed between the dust cup and the filter forms a peripheral surface. The cleaning liner may be an annular liner attached to a plurality of shafts depending from the handle body outside the exhaust tube. Corresponding to the action of cyclone dust collection, the exhaust part is provided as an exhaust tube at the center of the vortex. The filter is stretched so as to form the peripheral surface of the exhaust pipe. Therefore, fine dust that cannot be removed by centrifugation is captured on the outer peripheral surface of the cylindrical filter, and the air that has passed through the filter is exhausted through the inside of the exhaust pipe. By attaching an annular cleaning liner, preferably at the tip of the shafts hanging from the handle body on the outside of the exhaust tube, the annular cleaning liner is raised through the shaft together with the handle body by utilizing the pop-up action of the handle body. Move. The cleaning liner that moves upward slides on the filter surface of the filter and scrapes off the trapped dust.

  In the cyclone vacuum cleaner provided with the exhaust pipe, the lower part of the exhaust pipe occupies a shielding member that partitions the dust cup into an upper cyclone dust collection chamber and a lower dust collection chamber, and a position in the dust collection chamber A lower assembly comprising a suppression valve can be detachably attached. The shielding member constituting the lower assembly prevents dust accumulated in the lower dust collection chamber from flying up to the upper cyclone dust collection chamber, and the suppression valve also has, for example, a cross-shaped fixed blade structure. This prevents the generation of airflow that causes dust to rise in the lower dust collection chamber. The lower assembly can be disposed in the dust cup by attaching the lower assembly to the lower portion using an exhaust pipe. In addition, by making the attachment to the lower part of the exhaust pipe detachable, the exhaust pipe and the lower assembly can be disassembled and cleaned, and the convenience is improved.

  The cyclone vacuum cleaner according to the present invention is a type of vacuum cleaner in which the cyclone dust collector is accommodated in the vacuum cleaner body as described above, and in a state where the handle body is not popped up, the handle body is accommodated in the dust collector body. The external appearance of the machine can be improved and the space around the dust collector body can be saved. When the handle body is popped up from the dust collector main body, the handle body can be gripped, and the operability when handling the cyclone dust collector is improved. That is, the cyclone dust collector can be taken out of the main body of the cleaner so as to be integrally lifted, and the cyclone dust collector can be carried with the handle body held. The same applies to the case where the cyclone dust collector is returned to the vacuum cleaner main body after dust processing and cleaning. Therefore, a clean appearance can be maintained when the cyclone dust collector is housed in the vacuum cleaner body, and the operation when removing the cyclone dust collector from the vacuum cleaner body and the carrying after the removal can be performed more easily and reliably. .

  In addition, when the vacuum cleaner main body is further equipped with a cover that can be attached to and detached from the vacuum cleaner main body, an operation unit that operates to engage and disengage the vacuum cleaner main body, and a cyclone dust collector that is linked to the operation of the operation unit. By having an interlocking mechanism that switches the engaging portion between the engaged state and the released state, the interlocking mechanism is connected to the handle body by the engaging portion in conjunction with the disengaging operation of the cover from the cleaner body. Release the engagement with the dust collector body. Therefore, engagement and disengagement of the cover from the cleaner body and pop-up of the handle body can be realized with one touch operation, and the operability of the cyclonic cleaner can be further improved. Furthermore, by providing the cyclone dust collector with a filter cleaning mechanism that is linked to the pop-up operation of the handle body, the brush and filter are moved by moving the cleaning means (for example, brush) in the axial direction of the exhaust pipe in conjunction with the operation of the handle body. And scrape the dust adhering to the filter. Thereby, the filter can be automatically cleaned when the handle body is popped up or when the cover is opened, and the convenience of the cyclonic vacuum cleaner can be further improved.

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. Since the shaft 52 penetrates the lid bottom plate 14, a shaft seal 53 is provided in the through hole 14 a of the lid bottom plate 14 to seal between the cyclone dust collection chamber 12 b and the lid bottom plate 14.

  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 up via the shaft 52 and slides on the filter surface side of the filter 15a of the exhaust pipe 15. As a result, fine dust collected on the filter 15a is scraped off by the cleaning ring 50 and dropped into the cyclone dust collecting chamber 12b.

  Next, operation | movement of the cyclone type vacuum cleaner 1 by the said structure is demonstrated. When the cyclone dust collector 10 is housed in the vacuum cleaner main body 2 and the handle body 30 of the cyclone dust collector 10 is pushed down to engage the handle clamp 36, the coil springs 35 and 35 are held in a compressed state, and the dust collector main body 11 and the dust cup 12 can be fixed by a holder 23. In this state, the cover 7 can be closed to the cleaner body 2, and the cover 7 is kept closed by the operation unit 40.

  From this state, when the pressing button of the operation unit 40 is pressed on the cover 7, the handle clamp 36 is operated via the interlocking mechanism 41 as shown in FIG. 1, and the engagement by the handle clamp 36 is released. The handle body 30 pops up from the initial position accommodated in the lid body 13 by the restoring force of the coil springs 35 and 35. At this time, the opened cover 7 is further opened by the handle body 30 that pops up, so that the user can improve the trash disposal operability thereafter. At the same time, the cleaning tool 17 moves upward relative to the stationary exhaust cylinder 15. Accordingly, the filter 15 a covered with the exhaust cylinder 15 slides relative to the cleaning ring 50 of the cleaning tool 17, and dust attached to the filter 15 a is scraped off by the cleaning ring 50. The pop-up movement of the handle body 30 is preferably performed until the cleaning ring 50 comes into contact with the lid bottom plate 14, and the filter 15a is slid over the entire range.

  When the dust accumulated in the dust cup 12 of the cyclone dust collector 10 is thrown into the trash box, the handle body 30 popped up is grasped, and the dust collector body 11 and the dust cup 12 are integrated to completely remove the dust body 12 from the cleaner body 2. The dust inside the dust cup 12 can be discarded by taking out and releasing the lock of the holder 23 and removing the dust cup 12 from the dust collector main body 11.

  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 dust collector main body 11 and the dust cup 12 are fitted with the handle body 30 in the pop-up state, and are locked and integrated by the holder 23. The cyclone dust collector 10 is accommodated in the cleaner body 2 by grasping the handle body 30. 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. The cleaning tool 17 and the exhaust pipe 15 also move relatively downward, and the filter 15 a covered with the exhaust pipe 15 slides relative to the brush of the cleaning tool 17. Therefore, even when the cyclone dust collector 10 is housed in the cleaner body 2 even when the cyclone dust collector 10 is taken out from the cleaner body 2, even if dust remains in the filter 15 a without being scraped off, The dust remaining on the filter 15 a when the 30 is pushed in can be scraped off by the cleaning ring 50.

  As described above, in the present embodiment, in the cyclone dust collector 10, the filter 15 a covered with the exhaust pipe 15 and the cleaning tool 17 are slid through the connecting means 18 in conjunction with the pop-up operation of the handle body 30. Let Thus, in the cyclone dust collector 10, the filter 15 a is automatically cleaned by the cleaning tool 17 in response to the pop-up operation of the handle body 30. Therefore, the convenience of the vacuum cleaner of the type in which the cyclone dust collector 10 is accommodated in the cleaner body 2. Can be improved.

  The filter 15a is cleaned by the cleaning tool 17 when the handle body 30 is popped up in the cyclone dust collector 10. At this time, the cyclone dust collector 10 is integrated with the dust collector body 11 and the dust cup 12 not separated. Therefore, the dust scraped off from the filter 15a by the cleaning tool 17 does not leak to the outside of the cyclone dust collector 10 during this operation.

  In addition, by cleaning the filter 15a during the pop-up operation of the handle body 30 in the cyclone dust collector 10, it is possible to save time for collecting dust scraped off from the filter 15a by the cleaning in the dust cup 12. Thereby, when the dust cup 12 is removed from the dust collector main body 11, the dust is almost accumulated in the dust cup 12, so that the dust scraped off from the filter 15 a is between the dust collector main body 11 and the dust cup 12. Therefore, the cyclone vacuum cleaner 1 having excellent hygiene can be provided.

  Moreover, in this embodiment, since the cover 7 which opens and closes the upper part with respect to the cleaner body 2 is provided, and the pop-up operation of the handle body 30 is performed via the interlocking mechanism 41 interlocking with the opening and closing operation of the cover 7, When the cover 7 is opened, the filter 15a provided in the exhaust pipe 1 can be reliably cleaned when the cover 7 is opened. Also, when the handle body 30 is pushed into the cyclone dust collector 10, the cleaning tool 17 is moved relative to the exhaust cylinder 15 in the opposite direction. Therefore, according to the above configuration, the filter 15a can be reliably cleaned even when the cyclone dust collector 105 is housed in the cleaner body 2.

  FIG. 9 is a partial cross-sectional view of a cyclone dust collector and a cover portion of another embodiment of the cyclonic vacuum cleaner according to the present invention. In this example, when the user presses the cover 7 itself, the handle clamp 36 can be released using the cover itself generated at that time. That is, the cover 7 is provided with an action portion 55 corresponding to the handle clamp 36, and the action portion 55 occupies a position in contact with the claw member 37 of the handle clamp 36 in the normal state of the cover 7. . In this example, the cover 7 itself and the action part 55 function as an interlocking mechanism. When the cover 7 is displaced by, for example, pushing the right end as an operation portion in FIG. 9, the action portion 55 pushes the claw member 37 of the handle clamp 36 by the distal end portion 56 due to the displacement of the cover 7, The engagement with the engagement portion 38 of the handle body 30 is released by the rotation of 37.
