Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vacuum cleaner provided with a cyclone dust collector for centrifuging dust contained in air by swirling sucked air, and particularly to cleaning a filter on the surface of an exhaust pipe of a cyclone dust collector. It relates to a vacuum cleaner.
[0002]
[Prior art]
Conventionally, various vacuum cleaners provided with a cyclone dust collector have been proposed. The cyclone dust collector has an exhaust pipe having an exhaust port formed on a peripheral surface, and discharges air after dust is centrifugally separated to the outside via the exhaust pipe.
[0003]
At this time, due to the high-speed rotation of the air in the cyclone dust collector, dust in the air is almost centrifuged, but fine dust is not centrifuged and may be discharged from the exhaust stack together with the air. Therefore, a mesh-shaped filter is usually provided on the peripheral surface of the exhaust pipe so as to cover the exhaust port, and fine dust is removed by this filter.
[0004]
By the way, if such a vacuum cleaner is used for a long time, the filter is clogged, and the suction force and the dust collecting ability are reduced. In recent years, a cleaning tool (eg, a brush) for cleaning the filter is provided in the cyclone dust collector. A vacuum cleaner has been proposed in which the above-described disadvantage is avoided by periodically cleaning the filter (see, for example, Patent Document 1).
[0005]
The vacuum cleaner disclosed in Patent Document 1 discharges a cleaning means (for example, a brush) in conjunction with the attaching / detaching operation when attaching / detaching a dust cup for accumulating dust separated by centrifugation in the cyclone body to / from the cyclone body. By moving the brush and the filter in the axial direction of the cylinder, dust attached to the filter is scraped off. Thus, the filter can be automatically cleaned when the dust cup is attached / detached, and the convenience of the vacuum cleaner is improved.
[0006]
[Patent Document 1]
JP-A-2002-315701 (published on October 29, 2002)
[0007]
[Problems to be solved by the invention]
By the way, in the electric vacuum cleaner of patent document 1, a cyclone dust collector is provided in the middle of the air intake path (connection hose) from the suction opening body to the cleaner main body. That is, the cyclone dust collector is provided outside the cleaner body in which the electric blower is housed. In this type of vacuum cleaner, since the cyclone dust collector is exposed to the intake path, the dust cup itself can be freely attached to and detached from the cyclone body in this state. The filter can be cleaned in conjunction with the operation.
[0008]
However, in a vacuum cleaner of a type in which a cyclone dust collector is housed in a vacuum cleaner main body, even if the filter cleaning mechanism as in Patent Document 1 is applied as it is, in a state where the cyclone dust collector is housed in the vacuum cleaner main body, only a dust cup is provided. Cannot be removed from the cyclone body alone. Therefore, when cleaning the filter, it is necessary to once remove the cyclone dust collector itself from the cleaner body, and then remove the dust cup from the cyclone body in that state.
[0009]
However, in the filter cleaning mechanism of Patent Document 1, the removal of the dust cup from the cyclone body and the cleaning of the filter by the brush are performed at the same time. Therefore, in the above-described type of vacuum cleaner to which the filter cleaning mechanism is applied, When removing the dust cup from the cyclone body outside the vacuum cleaner body, the dust scraped off from the filter by the brush is removed from the gap between the dust cup and the cyclone body before being collected in the dust cup. May leak. In this case, there is a problem that the hygiene of the room is impaired.
[0010]
The present invention has been made to solve the above problems, and an object of the present invention is to automatically clean a filter covered by an exhaust pipe in a vacuum cleaner of a type in which a cyclone dust collector is housed in a vacuum cleaner body. It is another object of the present invention to provide a vacuum cleaner capable of suppressing dust leaked from the filter to the outside and improving hygiene.
[0011]
[Means for Solving the Problems]
According to the present invention, the sliding means slides the cleaning tool (for example, a brush) and the filter covering the exhaust port of the exhaust pipe in conjunction with the attaching / detaching operation of the cyclone dust collector to / from the cleaner body. Therefore, the filter is automatically cleaned by the cleaning tool at the same time as the attachment and removal of the cyclone dust collector to and from the vacuum cleaner main body, so that the convenience of the vacuum cleaner in which the cyclone dust collector is housed in the vacuum cleaner main body can be improved.
[0012]
Further, the cyclone dust collector includes, for example, a cyclone main body having the above-described exhaust pipe, a cleaning tool, and a sliding unit, and an accumulation container (dust cup) for accumulating dust centrifugally separated inside the cyclone dust collector. When the cyclone dust collector is attached to and detached from the cleaner body, the cyclone body and the dust collection container are in an integrated state, and during the attachment / detachment operation, dust scraped off from the filter by the cleaning tool is removed. Does not leak to the outside.
[0013]
Moreover, when the dust accumulated inside the cyclone dust collector is discarded in a trash can, it is necessary to remove the dust collection container from the cyclone body, but this removal is performed after removing the cyclone dust collector from the vacuum cleaner body. Therefore, by performing the above-described filter cleaning at the time of attaching / detaching the cyclone dust collector to / from the cleaner body, it is possible to save time for accumulating the dust scraped off from the filter by the cleaning in the dust collecting container. That is, it is possible to almost completely collect the scraped-off dust in the dust collecting container before removing the collecting container from the cyclone body. Therefore, when the dust container is removed from the cyclone body, the scraped-off dust hardly scatters to the outside through a gap formed between the cyclone body and the stacking container, thereby providing a vacuum cleaner with excellent hygiene. can do.
[0014]
Note that the vacuum cleaner of the present invention can also be expressed as follows. That is, in the above-described vacuum cleaner, the cyclone body includes a fixing plate to which the exhaust pipe is fixed, and a lid to which a second filter for removing dust contained in air exhausted from the exhaust pipe is mounted. Body, and the lid is provided so as to be able to be separated from and connected to the fixing plate, and a concave portion is provided inside, and a portion of the fixing plate facing the concave portion includes: A turning member biased in a turning direction such that a tip fits in the recess is provided, and the second filter is provided with the recess when the second filter is housed in the lid. In the state where the second filter is housed in the lid, when the fixing plate is covered with the lid, the tip of the rotating member contacts the stopper. While rotating to the fixed plate side while touching In a state where the second filter is not housed in the lid, when the fixing plate is covered with the lid, the tip of the rotating member fits into the concave portion, so that the rotation of the rotating member is prevented. It is a configuration that is blocked.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention will be described below with reference to FIGS. FIG. 2 shows a schematic configuration of the vacuum cleaner of the present invention.
[0016]
The vacuum cleaner of the present invention has a cleaner body 1, a connection hose 2, and a suction opening 3. The connection hose 2 constitutes a supply path for supplying the air sucked from the suction port body 3 to the cleaner body 1. The suction port body 3 sucks air through an air suction port (not shown) by the operation of the electric blower 4 described below.
[0017]
The cleaner main body 1 has an electric blower 4 and a cyclone dust collector 5. The electric blower 4 sucks air through the suction opening 3, the connection hose 2, and the cyclone dust collector 5. The cyclone dust collector 5 swirls the air sucked by the electric blower 4 to centrifuge dust contained in the air, and is provided detachably with respect to the cleaner body 1.
[0018]
In the above configuration, when the electric blower 4 accommodated in the cleaner body 1 is driven, air is sucked from the air suction port of the suction port body 3 and sent to the cyclone dust collector 5 via the connection hose 2. In the cyclone dust collector 5, dust contained in the air is centrifuged and collected in the dust cup 12 (see FIG. 1). On the other hand, the air from which dust has been removed is then discharged through an exhaust pipe 15 (see FIG. 1) and a filter section 16 (see FIG. 1) of the cyclone dust collector 5 (see FIG. 1). Is discharged outside the aircraft.
[0019]
Next, details of the cyclone dust collector 5 will be described with reference to FIG. FIG. 1 is a cross-sectional view showing a detailed configuration of the cyclone dust collector 5 in a housed state in the cleaner body 1.
[0020]
For convenience of the description below, the side of the vacuum cleaner to which the connection hose 2 (see FIG. 2) is connected is referred to as a front side, and the opposite side is referred to as a rear side. Also, the direction in which the cyclone dust collector 5 is taken out of the cleaner main body 1 is referred to as upward, and the direction in which the cyclone dust collector 5 is accommodated in the cleaner main body 1 is referred to as lower.
[0021]
As shown in FIG. 1, the cyclone dust collector 5 has a cyclone main body 11 and a dust cup 12 (dust collection container). That is, in the cyclone dust collector 5, the portion excluding the dust cup 12 constitutes the cyclone main body 11.
[0022]
The dust cup 12 is a container for accumulating dust centrifugally separated by the high-speed swirling of the sucked air, and has an open upper portion and is detachably connected to the cyclone body 11 via a packing (not shown). An air inlet 12a for introducing air supplied through the suction port 3 and the connection hose 2 into the machine is formed above the side surface of the dust cup 12. Above the inside of the dust cup 12, a cyclone dust collecting chamber 12b in which the air introduced through the air inlet 12a is swirled at a high speed is formed.
[0023]
The cyclone main body 11 includes a lid 13, a fixing plate 14, an exhaust pipe 15, a filter 16, a cleaning tool 17, and a sliding means 18. The present invention has a first feature in that the cyclone main body 11 is provided with the cleaning tool 17 and the sliding means 18, and has a second feature in that the cyclone body 11 is further provided with the filter portion 16. Hereinafter, each configuration will be described.
[0024]
The lid 13 is a substantially cylindrical container serving as an upper lid of the dust cup 12, and includes a top surface 19 and a side surface portion 20, and a joint side with the dust cup 12 is open. The top surface 19 may be formed with a depression serving as a handle so that the cyclone dust collector 5 can be gripped, but this can be made unnecessary by forming a bent portion 20a described later. When a depression is provided on the top surface 19, a portion of the top surface 19 excluding the depression is formed with a smooth curved surface that is flush with the upper surface of the cleaner body 1.
[0025]
The side surface portion 20 has a bent portion 20a and a hanging portion 20b. The bent portion 20 a hangs downward from the periphery of the top surface 19, bends toward the inside of the lid 13, and hangs down again. The hanging portion 20b hangs downward from the rear of the periphery of the top surface 19, and a cover body such that the tip thereof abuts on a receiving portion 31a of a positioning portion 31 of the cleaner body 1 to be described later in a state where the cyclone dust collector 5 is housed. 13 and bends down again.
[0026]
By forming the bent portion 20a on the side surface portion 20, when the cyclone dust collector 5 is popped up from the cleaner main body 1 by pressing a pressing button 35 described later, the bent portion 20a serves as a handle for the cyclone dust collector 5. Fulfill. Therefore, in this case, it is not necessary to provide a depression in the top surface 19 as described above, and the top surface 19 can be completely flush with the upper surface of the cleaner body 1. In this case, the appearance of the whole vacuum cleaner also improves.
[0027]
The formation position of the hanging portion 20b is not limited to the rear side of the side surface portion 20, and may be shifted in the circumferential direction of the side surface portion 20. In short, the hanging portion 20b may be formed corresponding to the position of the positioning portion 31 (receiving portion 31a) of the cleaner body 1.
[0028]
Here, FIG. 3 shows a plan view of the cleaner body 1, but in the present embodiment, the hanging portion 20 b does not contact a later-described locking portion 34 of the cleaner body 1 so as to be in contact with a side portion. 20 is formed so as to be displaced in the circumferential direction from the rear side of 20.
[0029]
Further, an opening (not shown) is formed in the side surface portion 20 through which a locking portion 34 described later on the cleaner body 1 side is inserted. The opening is vertically long (up and down) so that the locking portion 34 can move in the horizontal direction through the opening even when the cyclone dust collector 5 moves in the attaching / detaching direction (vertical direction) with respect to the cleaner body 1. Direction).
[0030]
The fixing plate 14 is detachably fixed to the lid 13 by closing an opening of the lid 13 on the dust cup 12 side. A disk-shaped packing (not shown) for tightly connecting the lid 13 and the dust cup 12 is attached to the fixing plate 14. An opening corresponding to the diameter of the exhaust tube 15 is formed at a substantially central portion of the fixing plate 14, and the exhaust tube 15 is fixed to the fixing plate 14 so that the opening coincides with the opening of the fixing plate 14. Fixed to. The fixing plate 14 has a hole (not shown) into which a connecting rod 44 described later is inserted.
[0031]
The exhaust pipe 15 is a cylinder having a plurality of exhaust ports for discharging air after centrifugal separation of dust in the cyclone dust collecting chamber 12b and having a plurality of exhaust ports opened on the peripheral surface. The filter 15a (first filter) is covered so as to cover it. The filter 15a is for removing fine dust that has not been removed by centrifugation in the cyclone dust collecting chamber 12b, and is formed, for example, in a mesh shape.
[0032]
One end of the exhaust pipe 15 in the axial direction is connected to the opening of the fixing plate 14 as described above. Therefore, the exhaust pipe 15 is integrated with the lid 13 via the fixing plate 14. On the other hand, the other end of the exhaust pipe 15 in the axial direction is connected to a check valve 21 having a cross shape as viewed in the axial direction. The suppression valve 21 is for preventing the dust in the dust cup 12 from rising due to the high-speed turning of the air in the cyclone dust collection chamber 12b.
[0033]
The filter section 16 further purifies the air exhausted from the exhaust pipe 15 and discharges the air to the outside of the cyclone main body 11. The detailed configuration thereof will be described later as a second feature of the present invention. .
[0034]
With the above configuration, the air introduced into the cyclone dust collecting chamber 12b from the air inlet 12a of the cyclone dust collector 5 is swirled at a high speed in the cyclone dust collecting chamber 12b, and passes through the filter 15a and the exhaust port on the peripheral surface of the exhaust pipe 15. And enters the exhaust pipe 15 through the exhaust pipe. At this time, most of the dust not removed from the air in the cyclone dust collecting chamber 12b is removed by the filter 15a.
[0035]
The air that has passed through the filter 15 a and the exhaust port travels inside the exhaust pipe 15 toward the axial lid 13, and is supplied to the filter section 16 through the opening of the fixing plate 14. The air is further purified by the filter unit 16 (dust that has not been removed by the filter 15a is removed), and is discharged from the exhaust port (not shown) of the filter unit 16 to the outside of the cyclone dust collector 5, and the cleaner body is removed. The air is exhausted to the outside of the cleaner main body 1 through an exhaust passage (not shown) and an electric blower 4.
[0036]
Next, before describing the cleaning tool 17 and the sliding means 18 as the first feature of the present invention, a mechanism (pop-up mechanism) for enabling the cyclone dust collector 5 to be attached to and detached from the cleaner body 1 will be described with reference to FIG. It will be described based on. As shown in the drawing, the cleaner body 1 has a positioning unit 31 and an operation unit 32.
[0037]
The positioning portion 31 is a member for positioning the storage position of the cyclone dust collector 5 in the cleaner main body 1, and the bottom portion of the cleaner main body 1 along the side surface of the dust cup 12 in the storage state of the cyclone dust collector 5. 1b. More specifically, the positioning portion 31 has a receiving portion 31a that horizontally receives a lower portion of a second support portion 41b (support portion 41) of the cyclone dust collecting portion 5 described later. One end of the receiving portion 31a extends in the direction of the bottom 1b of the cleaner body 1 along the side surface of the dust cup 12, while the other end extends in the direction opposite to the bottom 1b to form the positioning portion 31. ing.
[0038]
The operation unit 32 is for performing an operation of taking out the cyclone dust collector 5 from the cleaner body 1, and includes a support unit 33, a locking unit 34, a press button 35, and a rotating unit 36. I have.
[0039]
The support part 33 is for supporting the locking part 34 and has a horizontal support part 33a and a wall part 33b. The horizontal support portion 33a slidably supports the locking portion 34 in a direction (horizontal direction) in which the locking portion 34 locks or releases a locked portion 43 of the cyclone dust collector 5 described later. The wall portion 33b is formed on the opposite side to the storage position of the cyclone dust collector 5 and substantially perpendicular to the horizontal support portion 33a. When the cyclone dust collector 5 is taken out from the cleaner main body 1, the locked portion 43 is formed. Unnecessary sliding of the locking portion 34 in the direction to release the locking is prevented. In other words, when the locking portion 34 slides to the point where the locked portion 43 is completely unlocked, the rear end of the locking portion 34 (the end portion opposite to the contact side with the locked portion 43). ) Comes into contact with the wall portion 33b, so that the locking portion 34 is prevented from sliding more than necessary.
[0040]
The locking portion 34 locks the locked portion 43 of the cyclone dust collector 5 when the cyclone dust collector 5 is accommodated in the cleaner body 1, and has a tip (a contact side with the locked portion 43). Has a tapered shape that spreads downward from above. In addition, the locking portion 34 has a concave portion 34a at a substantially central portion in the sliding direction into which a tip of an arm portion 36b of the rotating portion 36 described later fits. Therefore, the tip of the arm portion 36b rotates while abutting on the inner surface of the concave portion 34a, so that the locking portion 34 itself slides in the horizontal direction while being supported by the support portion 33.
[0041]
The width of the concave portion 34a in the sliding direction of the locking portion 34 is set to such a degree that the rotation of the arm portion 36b is prevented from being hindered by the contact of the arm portion 36b with the opening of the concave portion 34a. Good.
[0042]
The pressing button 35 is a button for releasing the locking of the locked part 43 by the locking part 34 when the cyclone dust collector 5 is taken out from the cleaner body 1, and is fixed to the arm part 36 b of the rotating part 36. Have been.

The rotating portion 36 is configured to rotate in accordance with the pressing operation of the pressing button 35 to slide the locking portion 34 in a direction for locking the locked portion 43 or releasing the locking. It has a dynamic shaft 36a and an arm 36b. One end of the arm portion 36b is fixed to the rotating shaft 36a, while the other end is fitted in the concave portion 34a of the locking portion 34 and comes into contact with the inner surface of the concave portion 34a. The arm portion 36b is formed so as to be bent from the rotation shaft 36a and head toward the concave portion 34a.
[0044]
Further, the operation unit 32 includes a first urging unit (for example, a spring) (not shown). The first urging means is arranged so that the locking portion 34 slides in the direction in which the locked portion 43 is locked. The arm 36b is urged. Accordingly, except when the push button 35 is pressed, the arm portion 36b is slid in the direction in which the locking portion 34 locks the locked portion 43 by the rotation in the biasing direction. The part 34 is always placed at a position where the locked part 43 is locked.
[0045]
The first urging means does not urge the arm portion 36b itself in the rotation direction, but urges the locking portion 34 itself in the direction in which the locked portion 43 is locked. Is also good. That is, as shown in FIG. 10, a configuration may be such that a biasing unit 37 such as a spring is provided as the first biasing unit between the locking unit 34 and the wall 33b. Hereinafter, the first biasing means includes any one of a configuration for biasing the arm portion 36b itself, a configuration for biasing the locking portion 34 itself, and a configuration for biasing both.
[0046]
Although not shown, the operation unit 32 has a limiting member that limits the rotation of the arm 36b. This restricting member is provided with a concave portion 34a of the locking portion 34 to prevent the locking portion 34 from further sliding in the direction toward the inside of the cyclone dust collector 5 from the locking position for locking the locked portion 43. The rotation of the arm 36a due to the movement (the rotation in the clockwise direction in FIG. 1) is restricted.
[0047]
As described above, if the configuration for urging the locking portion 34 itself and the configuration for restricting the rotation of the arm portion 36b are used in combination, the locking portion 34 can securely lock the locked portion 43. The rattling of the cyclone dust collector 5 housed in the cleaner body 1 and the rattling of the arm 36b can be eliminated. Also, even if the cleaner main body 1 is shocked due to dropping during carrying or collision with the outside, the locking of the locked portion 43 by the locking portion 34 is inadvertently released. Can be prevented. Thereby, the cyclone dust collector 5 can be prevented from inadvertently jumping out of the cleaner main body 1, and a vacuum cleaner of a safe design can be provided.
[0048]
With the above configuration, as a whole, the operating unit 32 releases the locking of the locking unit 34 with the locked unit 43 by the pressing operation of the pressing button 35 when removing the cyclone dust collector 5 from the cleaner body 1. Function to perform the necessary operations.
[0049]
Next, the cleaning tool 17 and the sliding means 18 as the first feature of the present invention will be described with reference to FIG.
[0050]
The cleaning tool 17 cleans the filter 15a by sliding on the filter 15a on the peripheral surface of the exhaust pipe 15. The brush that slides on the filter 15a along the peripheral surface of the filter 15a, and supports the brush. And a flat supporting member. The cleaning tool 17 is disposed, for example, at a position in contact with the fixing plate 14 when the cyclone dust collector 5 is housed in the cleaner body 1.
[0051]
The sliding means 18 slides the cleaning tool 17 and the filter 15a in conjunction with the attachment / detachment operation of the cyclone dust collector 5 with respect to the cleaner body 1, and includes a support portion 41, a second biasing means 42, It has a locked portion 43 and a housing 45.
[0052]
The housing 45 accommodates the second urging means 42 inside the lid 13 and is fixed to the fixing plate 14. Therefore, the housing 45 is formed integrally with the lid 13 via the fixing plate 14. Further, a vertically long opening (not shown) into which the support portion 41 is inserted is formed on the side surface of the housing 45, and the support portion 41 traverses the housing 45 via the opening, and the housing 45 is closed. The body 45 is vertically movable relative to the support portion 41.
[0053]
The support section 41 includes a first support section 41a and a second support section 41b. The first support portion 41 a is formed of a flat plate extending in the horizontal direction, and a part of the first support portion 41 a is located inside the housing 45, and the remaining portion is provided outside the housing 45 through the opening of the housing 45. It protrudes horizontally. The first support portion 41a is connected to the cleaning tool 17 via a connecting rod 44 extending in a direction along the axial direction of the exhaust pipe 15.
[0054]
The second support portion 41b is formed integrally with the first support portion 41a, and has a shape that hangs downward from the side (rear) of the first support portion 41a. The second support portion 41b is supported by the positioning portion 31 by the lower end of the second support portion 41b coming into contact with the above-described positioning portion 31 (receiving portion 31a) on the cleaner body 1 side.
[0055]
Therefore, the support portion 41 including the first support portion 41a and the second support portion 41b is connected to the cleaning tool 17 via the connection rod 44 as a whole, and the positioning portion 31 provided on the cleaner body 1 side. It can be said that it is supported by.
[0056]
The second urging means 42 is formed of, for example, a spring, and one end of the second urging means 42 is supported by a surface of the first support portion 41a opposite to the support surface of the connecting rod 44, and the other end is formed of a spring. It is supported by the wall surface of the housing 45 at a position facing the first support portion 41a via the two urging means 42. That is, the second urging means 42 is located above the support portion 41.
[0057]
Here, as described above, the first support portion 41a is integrally formed with the second support portion 41b, and the second support portion 41b is supported by the positioning portion 31 of the cleaner main body 1. Therefore, the second urging means 42 urges the housing 45 upward with the support portion 41 supported by the positioning portion 31 as a fulcrum, and integrally with the housing 45 via the fixing plate 14. Is urged upward. Therefore, when the lid 13 is lifted upward by the urging force of the second urging means 42, the exhaust pipe 15 fixed to the lid 13 via the fixing plate 14 also moves relative to the stationary cleaning tool 17. Will move upward.
[0058]
For this reason, the second urging means 42 is configured such that the exhaust pipe 15 fixed to the lid 13 of the cyclone main body 11 via the fixing plate 14 moves the support section 41 It can be said that the lid 13 is urged with the fulcrum as a fulcrum.
[0059]
The locked portion 43 is a portion that is locked by the locking portion 34 of the cleaner main body 1 at the storage position of the cyclone dust collector 5 in the cleaner main body 1, and is fixed to the fixing plate 14. Therefore, the upward biasing force acting on the housing 45 and the lid 13 by the second biasing means 42 also acts upward on the locked portion 43 fixed via the lid 13 and the fixing plate 14. Therefore, when the cyclone dust collector 5 is housed in the cleaner main body 1, the locked portion 43 is opposed by the locking portion 34 of the cleaner main body 1 against the urging force of the second urging means 42. Locked.
[0060]
Next, the operation of the above configuration will be described.
In a state where the cyclone dust collector 5 is housed in the cleaner body 1, the locking portion 34 is slid in the direction in which the locked portion 43 is locked by the urging force of the first urging means of the operation portion 32, and The locking portion 43 is locked by the locking portion 34.
[0061]
At this time, as described above, the housing 45 is subjected to an upward urging force by the second urging means 42 with the support portion 41 as a fulcrum, but the locked portion 43 is By being locked, the housing 45 and the cyclone dust collector 5 including the same cannot move upward due to the urging force. That is, the cyclone dust collector 5 is accommodated in the cleaner main body 1 in a state where the upward urging force of the second urging means 42 is acting on the locked portion 43.
[0062]
When the push button 35 of the operation unit 32 is pressed from this state, as shown in FIG. 4, the locking unit 34 slides in a direction to release the locking with the locked unit 43 by the rotation of the arm 36 b. . Then, since the locking of the locked portion 43 by the locking portion 34 is released, the housing 45 and the entire cyclone dust collector 5 including the housing 45 are cleaned by the upward urging force of the second urging means 42. The user moves upward (pops up) from the first storage position in the main body 1. The upward movement of the cyclone dust collector 5 is performed until the fixing plate 14 to which the housing 45 is fixed abuts on the support 41 (first support 41a).
[0063]
At this time, a reaction force in the opposite direction (downward direction) to the upward urging force of the second urging means 42 is acting on the support portion 41, but the support portion 41 is The supporting portion 41 does not move downward because it is supported by the positioning portion 31 on the side (the receiving portion 31a receiving the downward reaction force). Therefore, the cleaning tool 17 connected to the support portion 41 via the connection rod 44 does not move and remains stationary.
[0064]
Further, since the exhaust pipe 15 is fixed to the lid 13 via the fixing plate 14, the exhaust pipe 15 also moves with respect to the stationary cleaning tool 17 as the lid 13 and the fixing plate 14 move upward. Move relatively upward. As a result, the filter 15a coated on the exhaust pipe 15 slides relatively to the brush of the cleaning tool 17, and dust attached to the filter 15a is scraped off by the brush. The cleaning tool 17 relatively moves below the exhaust pipe 15 due to the relative upward movement of the exhaust pipe 15.
[0065]
When the dust collected in the dust cup 5b of the cyclone dust collector 5 is thrown away in the trash box, the popped-up cyclone dust collector 5 is completely removed from the cleaner body 1, and only the dust cup 5b is removed from the cyclone body 11, so that the dust cup is removed. The dust inside 5b can be discarded.
[0066]
Next, when storing the removed cyclone dust collector 5 in the cleaner body 1 again, the cyclone dust collector is kept until the tip of the support portion 41 (second support portion 41b) of the cyclone dust collector 5 contacts the positioning portion 31. 5 is housed in the cleaner body 1, and when the above-mentioned tip comes into contact, the lid 13 is pushed downward from there against the urging force of the second urging means 42.
[0067]
At this time, a reaction force in a direction opposite to the upward biasing force of the second biasing means 42 acts on the support portion 41 in the same manner as described above. And the supporting portion 41 does not move downward because it is in contact with the positioning portion 31 (receiving portion 31a) and is supported by the positioning portion 31. Therefore, the cleaning tool 17 connected to the support portion 41 via the connecting rod 44 does not move and remains stationary.
[0068]
When the lid 13 is continuously pushed downward, the exhaust pipe 15 integrated with the lid 13 also moves downward relative to the cleaning tool 17, and the filter 15a covered by the exhaust pipe 15 is removed. , Slide relative to the brush of the cleaning tool 17. Therefore, even when dust is left on the filter 15a without being scraped off when the cyclone dust collector 5 is taken out of the cleaner main body 1, the filter 15a is stored when the cyclone dust collector 5 is stored in the cleaner main body 1. Dust remaining on the brush can be scraped off by the brush.
[0069]
On the other hand, after the cyclone dust collector 5 is removed from the cleaner main body 1, the pressing of the pressing button 35 is released, so that the locking portion 34 engages the locked portion 43 by the urging force of the first urging means. You have already slid to a position where you can stop.
[0070]
Therefore, when the lid 13 is pressed downward, the locked portion 43 fixed to the lid 13 via the fixing plate 14 eventually comes into contact with the tip of the locking portion 34. At this time, since the distal end of the locking portion 34 is formed in a tapered shape extending downward from above, the locking portion 34 releases the locking of the locked portion 43 by pressing the lid 13 downward. The force is applied in the direction, that is, in the direction away from the cyclone dust collector 5. Thereby, the locking part 34 slides in a direction away from the cyclone dust collector 5 as the locked part 43 descends. Accordingly, the inner surface of the concave portion 34a of the locking portion 34 comes into contact with the arm portion 36b, and slightly rotates the arm portion 36b.
[0071]
When the descending locked portion 43 has completely passed the sliding position of the locking portion 34, no force is applied to the locking portion 34 in the unlocking direction. Due to the urging force of the first urging means, the slider 43 is slid again to a position where the locked portion 43 is locked. At this time, the tip of the hanging portion 20b of the lid 13 abuts on the receiving portion 31a of the positioning portion 31, and the storage of the cyclone dust collector 5 in the cleaner body 1 is completed.
[0072]
When the locking portion 34 is slid to the above position, the locked portion 43 is locked on the lower surface of the locking portion 34, so that the pressing of the lid 13 downward can be stopped. , The cyclone dust collector 5 does not fly upward.
[0073]
As described above, in the present embodiment, the sliding means 18 slides the filter 15 a covered with the exhaust pipe 15 and the cleaning tool 17 in conjunction with the attaching / detaching operation of the cyclone dust collector 5 to / from the cleaner body 1. . As a result, the filter 15a is automatically cleaned by the cleaning tool 17 at the same time when the cyclone dust collector 5 is attached to and removed from the cleaner main body 1, so that the convenience of the vacuum cleaner of the type in which the cyclone dust collector 5 is accommodated in the cleaner main body 1 is provided. Can be improved.
[0074]
Further, the cleaning of the filter 15a by the cleaning tool 17 is performed at the time of the attachment / detachment operation of the cyclone dust collector 5 to / from the cleaner main body 1. At this time, the cyclone dust collector 5 does not separate the cyclone main body 11 and the dust cup 12, but integrally. In this operation, the dust scraped off from the filter 15a by the cleaning tool 17 does not leak to the outside of the cyclone dust collector 5 during this operation.
[0075]
In addition, by cleaning the filter 15a at the time of attaching and detaching the cyclone dust collector 5 to and from the cleaner body 1, it is possible to save time for accumulating the dust scraped off from the filter 15a by the cleaning into the dust cup 12. Thus, when the dust cup 12 is removed from the cyclone body 11, since the dust is almost completely accumulated in the dust cup 12, the dust scraped off from the filter 15a is removed between the cyclone body 11 and the dust cup 12. It is possible to provide a vacuum cleaner with excellent hygiene, with almost no scattering to the outside from the gap.
[0076]
Further, in the present embodiment, the cyclone body 11 includes the fixing plate 14 to which the exhaust pipe 15 is fixed, and the sliding means 18 is connected to the cleaning tool 17 via the connecting rod 44 and the cleaner The support part 41 supported by the positioning part 31 provided on the main body 1 side, and the housing 45 fixed to the fixing plate 14 with the support part 41 as a fulcrum in the direction of taking out the cyclone dust collector 5 from the cleaner main body 1. And second urging means 42 for urging.
[0077]
Thus, when the housing 45 is moved in the take-out direction by the urging force of the housing 45 in the take-out direction by the second urging means 42, the exhaust pipe 15 fixed to the fixing plate 14 also moves in the take-out direction. Will do. Therefore, the exhaust pipe 15 moves relatively to the cleaning tool 17 connected to the support portion 41 via the connecting rod 44, and when the cyclone dust collector 5 is taken out from the cleaner body 1, the filter 15a is removed. Can be reliably cleaned.
[0078]
Also, when the cyclone dust collector 5 is moved in the housing direction of the cleaner body 1 against the urging force of the second urging means 42, the exhaust pipe 15 is relatively moved with respect to the cleaning tool 17. And move in the opposite direction. Therefore, according to the above configuration, even when the cyclone dust collector 5 is housed in the cleaner body 1, the filter 15a can be reliably cleaned.
[0079]
Further, in the present embodiment, the cyclone main body 11 is locked at the storage position of the cyclone dust collector 5 in the cleaner main body 1 and against the urging force of the second urging means 42, the locking portion 34 on the cleaner main body 1 side. And a locked portion 43 locked by the locking member. Thus, in a state where the cyclone dust collector 5 is housed in the cleaner main body 1, the locked portion 43 is locked by the locking portion 34, so that the cyclone dust collector 5 is kept stationary in the cleaner main body 1. Can be held.
[0080]
Further, in the present embodiment, the cleaner main body 1 operates the operating portion 32 for releasing the locking of the locking portion 34 with the locked portion 43 by a pressing operation of the pressing button 35 when the cyclone dust collector 5 is taken out. Have. Accordingly, the moment the lock of the locked portion 43 is released by the locking portion 34 by the pressing of the pressing button 35, the cyclone dust collector 5 is moved in the above-described biasing direction by the biasing force of the second biasing means 42. (Pop-up). Therefore, the cyclone dust collector 5 can be taken out of the cleaner main body 1 in conjunction with the pressing operation of the press button 35, and the filter 15a can be cleaned by the cleaning tool 17 in conjunction with the taking-out operation.
[0081]
In the vacuum cleaner described in the present embodiment, when the cleaner main body 1 is placed in the vertical state, a blocking portion (lock release) that prevents the locking portion 34 from unlocking the locked portion 43 when the cleaner main body 1 is placed vertically. The blocking unit may be provided on the cleaner body 1. As such a blocking portion, for example, a configuration in which an obstacle (for example, a small ball) that hinders the pressing operation is arranged in a space where the pressing button 35 is pressed when the vacuum cleaner is placed vertically. A configuration in which the obstacle is arranged between the rear end of the locking portion 34 and the wall portion 33b is conceivable.
[0082]
For example, FIG. 11 is a cross-sectional view illustrating a schematic configuration of a blocking portion 61 as an example of the lock release blocking portion. In addition, in the figure, the illustration of the rotating part 36 and the locking part 34 is omitted. The blocking portion 61 has a small steel ball 62 and a guide portion 63 that moves the steel ball 62 according to the installation state of the electric vacuum cleaner (the cleaner main body 1).
[0083]
As shown in FIG. 12A, the guide unit 63 presses (moves) the pressing button 35 in the horizontal state of the cleaner body 1 (the state in which the cyclone dust collector 5 is taken out in a substantially vertical direction). 12B, while the steel ball 62 is retracted from the space in which the cyclone dust collector 5 is placed vertically (the direction in which the cyclone dust collector 5 is taken out is substantially horizontal), as shown in FIG. The steel ball 62 is guided (moved) into the space where the pressing (movement) is performed, and a slope 63a for performing such guidance, and a housing 63b holding the slope 63a and the steel ball 62 are provided. It is composed of
[0084]
With this configuration, in a state where the cleaner body 1 is placed horizontally, the steel ball 62 falls down along the slope 63a and retreats from the pressing space, so that the pressing of the pressing button 35 is not hindered. Therefore, in conjunction with the pressing operation of the pressing button 35, the locking portion 34 slides in the direction to release the locking of the locked portion 43, and the cyclone dust collector 5 pops up. On the other hand, when the cleaner main body 1 is placed vertically, the steel ball 62 moves into the pressing space of the pressing button by the guidance of the slope 63 a, so that the pressing operation of the pressing button 35 is prevented by the steel ball 62. For this reason, the locking portion 34 interlocked with the pressing operation of the pressing button 35 does not slide, and the locked portion 43 remains locked, so that the cyclone dust collector 5 does not pop out by pop-up.
[0085]
As described above, when the vacuum cleaner main body 1 is set in the vertical position in which the taking-out direction of the cyclone dust collector 5 is substantially horizontal, the locking portion 34 with respect to the locked portion 43 is provided. It can also be said that it is provided with a blocking portion 61 (pressing operation blocking portion) for blocking the pressing operation (of the pressing button 35) in the operating portion 32 for releasing the locking of.
[0086]
In the horizontal state of the vacuum cleaner, even if the cyclone dust collector 5 is popped up, since the cyclone dust collector 5 has a certain degree of gravity, it depends on the urging force of the second urging means 42. There is almost no situation in which 5 jumps out of the cleaner body 1 due to inertial force. However, in the vertical state of the vacuum cleaner, if the cyclone dust collector 5 is popped up in the horizontal direction, the cyclone dust collector 5 easily jumps out of the cleaner main body 1 due to the inertial force in the horizontal direction, and the cyclone dust collector 5 falls. May be damaged. Therefore, by providing the above-described blocking portion (lock release blocking portion) in the cleaner main body 1, such inconvenience in the vertically installed state of the vacuum cleaner can be reliably prevented.
[0087]
In most cases, in a vacuum cleaner store, the vacuum cleaner is placed on a display shelf in a vertically installed state because of the arrangement space. In this case, without the above-mentioned lock release prevention part, for example, when the child suddenly presses the press button 35, the cyclone dust collector 5 popped up in the lateral direction may hit the child and cause injury. However, such a worst case can be prevented by providing the lock release prevention portion in the cleaner body 1 as in the present embodiment.
[0088]
Further, in the electric vacuum cleaner according to the present embodiment, as shown in FIG. 13, a configuration may be provided in which the third urging means 71 for urging the cyclone dust collector 5 in the takeout direction is provided in the cleaner main body 1. The above-mentioned second urging means 42 also urges the cyclone dust collector 5 in the take-out direction, but since the second urging means 42 is provided in the cyclone dust collector 5, these two are distinguished. In some cases, the second urging unit 42 is referred to as a cyclone-side urging unit, while the third urging unit 71 provided on the cleaner body 1 is referred to as a main-unit-side urging unit.
[0089]
The third urging means 71 is made of an elastic body such as a helical spring or a leaf spring. One end of the third urging means 71 is supported by the bottom 1 b of the cleaner main body 1, and the other end is inside the cleaner main body 1. The cyclone dust collector 5 accommodated in the dust collector 12 can be separated from or contacted with a locked portion 12 c provided on the side surface of the dust cup 12 or the bottom of the dust cup 12. Accordingly, the third urging means 71 urges the cyclone dust collector 5 that has come into contact with the locked portion 12c in the take-out direction. In the present embodiment, the locked portion 12c is formed to be bent inward from the side surface of the dust cup 12, but may be formed by a protrusion protruding outward from the side surface.
[0090]
The cleaning tool 17 provided in the cyclone main body 11 has an opening corresponding to the peripheral surface at the center in order to slide with the filter 15 a on the peripheral surface of the exhaust pipe 15. With such a structure, the cleaning tool 17 is connected to the connecting rod 44 at the end of the cleaning tool 17 in a so-called cantilevered state, as shown in FIGS. In such a cantilever state, since the cleaning tool 17 is supported by the connecting portion 44 in an unstable state, the cyclone dust collector 5 pops up in the removing direction by the urging force of the second urging means 42 and the cleaning tool 17 When the filter 15a and the filter 15a slide, the filter 15a is easily caught by the cleaning tool 17. As a result, the pop-up operation may not go smoothly.
[0091]
Here, in order to avoid such inconvenience, for example, a configuration in which the cleaning tool 17 is supported by the connecting rods 44 from both sides with the filter 15a interposed therebetween is also conceivable. However, in that case, the structure of the cyclone dust collector 5 itself becomes complicated, and the cyclone dust collector 5 becomes large, which hinders miniaturization of the vacuum cleaner. On the other hand, when the volume of the cyclone dust collecting chamber 12b is reduced without changing the size of the cyclone dust collector 5, the original dust collecting function of the cyclone dust collector 5 is reduced.
[0092]
Therefore, as shown in FIG. 13, the above-described third urging means 71 is provided in the cleaner main body 1 and the cyclone dust collector 5 is urged in the take-out direction, so that the cyclone dust collector by the urging force of the second urging means 42 is provided. The pop-up of No. 5 can be assisted by the urging force of the third urging means 71. As a result, the cyclone dust collector 5 can be reliably and smoothly popped up.
[0093]
At this time, it is desirable that the third urging means 71 be provided on the side opposite to the second urging means 42 with respect to the center axis which is the center of the rotation of the air in the cyclone dust collector 5. Accordingly, the cyclone dust collector 5 is urged in the take-out direction from both sides with the center axis interposed therebetween, so that the cyclone dust collector 5 can be more reliably and smoothly popped up.
[0094]
Next, a filter section 16 which is a second feature of the present invention will be described with reference to FIGS.
[0095]
FIG. 5 is a perspective view when the lid 13 of the cyclone body 11 is viewed from the side in contact with the fixing plate 14 (see FIG. 1). The lid 13 is provided so as to be detachable from the fixed plate 14. The above-described filter section 16 is formed inside the lid 13 and has a filter 51 (see FIG. 6), a filter housing section 52, a first concave section 53, and a second concave section 54. When the fixing plate 14 is fixed to the lid 13, the above-described housing 45 fixed to the fixing plate 14 fits into the second recess 54.
[0096]
The filter 51 is for removing dust contained in the air exhausted from the exhaust tube 15, and in the present embodiment, is formed in a shape in which a part of a disk is cut off as shown in FIG.
[0097]
The filter accommodating portion 52 accommodates the filter 51, and a hole 52a serving as a passage hole for the air that has passed through the filter 51 is formed on the upper surface thereof.
[0098]
When the filter 51 is not accommodated in the filter accommodating portion 52, the first concave portion 53 is rotated by the tip of a rotating member 14 a (see FIG. 9) fixed to the fixing plate 14 being fitted and abutting. It is the part that blocks. That is, when the filter 51 is not housed, the first recess 53 abuts on the tip of the rotating member 14a to form a rotation preventing portion that prevents the rotation of the rotating member 14a.
[0099]
The rotating member 14 a is rotatably fixed to a surface of the fixed plate 14 opposite to the surface to which the exhaust pipe 15 is fixed, and substantially facing the first recess 53. Are always urged in the rotating direction so as to fit into the first concave portion 53. The rotating member 14a is supported by the fixed plate 14 so as to be substantially perpendicular to the fixed plate 14. That is, the rotating member 14a is erected in a substantially vertical direction with respect to the fixed plate 14, and is supported by the fixed plate 14 so that its tip can rotate toward the fixed plate 14 against the urging force. Have been.
[0100]
Further, the length of the rotating member 14a is formed longer than the longest distance between the fixed plate 14 and the first concave portion 53 (the distance between the fixed plate 14 and the deepest portion of the first concave portion 53). Further, since the rotating member 14a stands upright in the substantially vertical direction with respect to the fixed plate 14, it is easy to rotate toward the fixed plate 14 by a force from above.
[0101]
Here, FIG. 7 shows a perspective view of the lid 13 in which the filter 51 is accommodated in the filter accommodating portion 52, and FIG. 8 shows the lid 13 to which the fixing plate 14 is fixed from the direction A in FIG. It shows a sectional view when viewed. As shown in FIG. 8, the filter accommodating portion 52 is arranged such that an air entry surface (hereinafter, referred to as a filter surface) of the filter 51 is inclined with respect to the axial direction of the exhaust pipe 15 (see FIG. 1). And a filter 51 is accommodated therein. Accordingly, the surface area of the filter surface can be increased as compared with the case where the filter surface is arranged perpendicular to the axial direction of the exhaust pipe 15, so that the dust collecting capability of the filter 51 can be increased as much as possible.
[0102]
As shown in FIG. 6, a stopper 55 is attached to the filter 51. When the filter 51 is accommodated in the lid 13 (the filter accommodating portion 52), as shown in FIG. 55 closes the first recess 53.
[0103]
According to the above configuration, when the filter 51 is attached to the filter 51 and the filter 51 is accommodated in the filter accommodating portion 52, the stopper 55 closes the first recess 53 as shown in FIG. When the lid 13 is placed vertically on the fixed plate 14 (or when the fixed plate 14 is placed vertically on the lid 13), the tip of the rotating member 14 a fixed to the fixed plate 14 is a stopper for the filter 51. Rotating toward the fixed plate 14 while abutting on 55. Thereby, the lid 13 and the fixed plate 14 can be further approached, and the lid 13 and the fixed plate 14 can be fixed closely. Since such an operation is performed, the stopper 55 attached to the filter 51 prevents the rotating member 14a from contacting the first concave portion 53 when the filter 51 is accommodated in the lid 13, and the stopper 55 rotates. It functions as a contact prevention member for rotating the tip of the moving member 14a toward the fixed plate 14 side.
[0104]
On the other hand, when the filter 51 is not accommodated in the filter accommodating portion 52, when the cover 13 is vertically placed on the fixing plate 14, as shown in FIG. And the rotation of the rotation member 14a is prevented. Therefore, the lid 13 cannot move any more in the direction of contact with the fixed plate 14, and the rotation member 14 a is formed with the above-described length. A gap d is formed between them. That is, in this state, the lid 13 and the fixing plate 14 cannot be fixed.
[0105]
As described above, in the present embodiment, the cyclone body 11 includes the lid 13 (or the filter unit 16) in which the filter 51 for removing dust contained in the air discharged from the exhaust pipe 15 is mounted. In addition, the filter 51 is provided not on the cleaner body 1 side but on the cyclone dust collector 5 side. Thereby, together with the dust cup 12 and the filter 15a covered with the exhaust pipe 15, all the members that need to be washed and cleaned can be collected on the cyclone dust collector 5 side.
[0106]
For example, if the filter 51 is provided in the cleaner main body 1 outside the cyclone dust collector 5, it is necessary to take out the filter 51 from the cleaner main body 1 separately from taking out the cyclone dust collector 5. A user who does not want to be troublesome tends to refuse maintenance such as cleaning and replacement of the filter 51. However, if the filter 51 is provided on the cyclone dust collector 5 side as in the present embodiment, for example, after the cleaning of the dust cup 12, maintenance such as cleaning and replacement of the filter 51 becomes easy, and the usability of the user is improved. It has the advantage of being better.
[0107]
Further, in the present embodiment, in a state where the filter 51 is housed in the lid 13, when the lid 13 is put on the fixing plate 14, the turning member 14 a Since the cover 13 rotates to the side 14, the lid 13 and the fixing plate 14 are brought into contact with each other as described above, and these can be integrated. On the other hand, in a state in which the filter 51 is not accommodated in the lid 13, when the lid 13 is put on the fixing plate 14, the tip of the pivoting member 14 a fits into the first recess 53, and the pivoting of the pivoting member 14 a is performed. Is prevented, so that the lid 13 does not close to the fixing plate 14. Therefore, the user can easily recognize that the filter 51 is in the non-accommodated state, and it is possible to reliably prevent a situation in which the vacuum cleaner is misused while the filter 51 is in the non-accommodated state. .
[0108]
In the present embodiment, an example in which the first concave portion 53 is formed as a rotation preventing portion in the lid 13 has been described, but when the filter 51 is not housed in the lid 13, the filter 51 comes into contact with the tip of the rotating member 14 a. The configuration is not limited to the concave portion (first concave portion 53) as long as the rotation of the rotating member 14a can be prevented. For example, when the filter 51 is not housed in the cover 13, a protrusion or a wall that prevents the rotation of the rotating member 14a may be provided on the cover 13 as the above-described rotation preventing portion.
[0109]
Note that the first urging means and the second urging means 42 described above can be formed of an elastic body such as a leaf spring, other than a spring (helical spring), similarly to the third urging means 71. It is.
[0110]
【The invention's effect】
According to the present invention, the sliding means slides the cleaning tool and the filter covering the exhaust port of the exhaust pipe in conjunction with the attaching / detaching operation of the cyclone dust collector to / from the cleaner body. Therefore, the filter is automatically cleaned by the cleaning tool at the same time as the attachment and removal of the cyclone dust collector to and from the vacuum cleaner main body, so that the convenience of the vacuum cleaner in which the cyclone dust collector is housed in the vacuum cleaner main body can be improved.
[0111]
In addition, when the cyclone dust collector is attached to and detached from the cleaner body, the cyclone body and the dust collection container constituting the cyclone dust collector are in an integrated state. The generated dust does not leak to the outside of the cyclone dust collector.
[0112]
Moreover, by performing the filter cleaning at the time of attaching and detaching the cyclone dust collector to and from the cleaner body, it is possible to save time for accumulating the dust scraped off from the filter by the cleaning in the dust collection container. Therefore, when the dust container is removed from the cyclone body after the cyclone dust collector is taken out from the vacuum cleaner body, the scraped dust rarely scatters outside through a gap formed between the cyclone body and the accumulation container. In addition, there is an effect that a vacuum cleaner having excellent hygiene can be provided.
