Description

  The present invention relates to a vacuum cleaner having a filter in a dust collection container.

  A vacuum cleaner of the type that has a dust collection container and an electric blower housing in the vacuum cleaner body and separates dust and air in the dust collection container, so-called cyclone type vacuum cleaner, collects conventional dust. The paper pack is not necessary and is widely used because it can be discarded when it is desired to collect and discard the dust. In these cyclone type vacuum cleaners, it is difficult to completely separate dust and air in the dust collecting container, and therefore a filter for removing dust is provided at the exhaust port of the dust collecting container. . (For example, refer to Patent Document 1).

However, the filter of the dust collecting container has a drawback that it is likely to be clogged because dust that is not separated in the dust collecting container adheres, and maintenance such as cleaning of the filter must be frequently performed.
Therefore, recently, a product has been proposed in which a disposable filter, for example, a tissue is attached upstream of the filter to prevent clogging of the filter and reduce the frequency of filter maintenance. A filter that opens and closes the opening of the dust collection container is provided so that the dust collected in the dust collection container can be easily discharged from the opening of the dust collection container. The opening of the dust container is open.
However, since the proposed product clamping mechanism is located in the vicinity of the insertion port of the storage chamber in which the dust collection container is stored, when the disposable filter is mounted in the dust collection container, the dust collection is performed. The disposable filter that protrudes from the container protrudes from the main body of the vacuum cleaner and has a disadvantage that it looks bad.

By inserting the rotary shaft 13a of the filter holding portion 13 into the hole of the attachment portion 17. The filter holder 13 can be rotated with respect to the dust collecting container 11. Reference numeral 18 denotes a clamp mechanism that holds the opening portion 14 in a closed state by the filter holding portion 13, and the clamp mechanism 18 is provided at a position facing the mounting portion 17. An operation lever 19 provided in the vicinity of the opening 14 on the rear surface side, a support portion 20 that supports the operation lever 19, and the filter holding portion 13 are formed to engage with a tip portion 19 a of the operation lever 19. And a protrusion 21.
A cover 22 is formed integrally with the dust collecting container 11 and is formed in a U shape from two connecting portions 23 extending forward, and covers the mounting portion 17 and the filter holding portion 13. Therefore, as shown in FIGS. 3 and 5, the attachment portion 17 and the filter holding portion 13 are not visible.
As shown in FIG. 3, a disposable filter 24 (in this embodiment, a commercially available tissue) is sandwiched between the opening 14 and the filter holding portion 13 and can be attached to the dust collecting container 11. It has become. Further, a substantially U-shaped frame 25 is rotatably attached to the filter holding portion 13 so that the end portion of the disposable filter 24 does not protrude greatly from the outer surface of the dust collecting container 11.
A storage chamber 26 for storing the dust collecting container 11 is provided above the electric blower 8. The storage chamber 26 has an insertion port 27 that is open at the front, and the dust collection container 11 can be inserted and stored through the insertion port 27.
By the way, when the dust collecting container 11 is stored in the storage chamber 26 with the disposable filter 24 attached, the back wall of the clamp mechanism 18 facing the insertion port 27 of the storage chamber 26 as shown in FIG. Since it is on the 28th side, that is, at a position away from the insertion port 27, the disposable filter 24 protruding from the dust collecting container 11 is configured not to protrude from the cleaner body 2. Further, since the cover 22 forms a part of the outer surface of the cleaner body 2, a separate part such as a cover for covering the storage chamber 26 is unnecessary. Furthermore, since the mounting portion 17 and the filter holding portion 13 are not visible by the cover 22, the appearance is good.

  In the vertical vacuum cleaner 1 configured as described above, air flows into the suction port 12 of the dust collection container 11 from the tip opening portion of the floor suction tool 3 or the handle 6 by driving the electric blower 8. Then, it is separated into large dust and air in the dust collecting container 11. Small dust is removed by the disposable filter 24, the mesh filter 15, the urethane filter 16, and the filter 10 at the communication port 9 when passing through the opening 14, and the clean air is removed from the electric blower 8. Is cooled and exhausted out of the cleaner body 2.

Since the clogging of the mesh filter 15 and the urethane filter 16 can be suppressed by disposing the disposable filter 24 on the upstream side of the mesh filter 15 and the urethane filter 16, maintenance of the mesh filter 15 and the urethane filter 16 is performed. Can be reduced. In addition, the disposable filter 24 can be mounted by being sandwiched between the opening 14 and the filter holding unit 13, thereby improving the mounting property of the disposable filter 24.
When discharging the dust accumulated in the dust collecting container 11, when the operation lever 19 is operated as shown in FIG. 4, the distal end portion 19 a of the operation lever 19 and the protrusion 21 are disengaged, The filter holding part 13 rotates and dust and the disposable filter 24 can be easily discharged from the opening part 14.

When the discharge is completed, a new disposable filter 24 is placed on the upper surface of the mesh filter 15, the filter holding unit 13 is rotated, and then the filter holding unit 13 is held by the clamp mechanism 18. Then, the dust collecting container 11 is inserted through the insertion port 27 and mounted in the storage chamber 26. At this time, since the clamp mechanism 18 is located on the back wall 28 side facing the insertion port 27 of the storage chamber 26, that is, at a position away from the insertion port 27, the disposable filter 24 protruding from the clamp mechanism 18. However, it does not protrude from the main body 2 of the cleaner, and the disadvantage that it looks bad can be solved.
Further, since the cover 22 of the dust collecting container 11 forms a part of the outer surface of the cleaner body 2, a separate part such as a cover for covering the storage chamber 26 is unnecessary, and the number of parts is reduced. be able to.
Moreover, in the state which accommodated the said dust collection container 11 in the said storage chamber 26, the said attaching part 17 and the said filter holding | maintenance part 13 are hidden by the said cover 22, and it can improve appearance.
In the present embodiment, the clamp mechanism 18 is configured to engage the tip portion 19s of the operation lever 19 with the protrusion 21 of the filter holding portion 13, but the tip portion 19a of the operation lever 19 without providing the protrusion, You may engage the filter holding | maintenance part 13 directly. Further, although the operation lever 19 is provided in the dust collecting container 11, it may be provided in the filter holding unit 13.
Further, in the present embodiment, the vertical vacuum cleaner type (upright vacuum cleaner) has been described, but the same effect can be obtained even when applied to a canister type.
Next, a second embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

The dust collecting container 11 according to the second embodiment is characterized by the shape of the filter holding portion 13, and the filter holding portion 13 shown in FIG. 6 is inclined so as to gradually become higher toward the clamp mechanism 18 side. Contrary to this, on the contrary, the filter holding portion 13 shown in FIG. 7 is inclined so as to gradually become lower toward the clamp mechanism 18 side.
As shown in FIG. 6, when it is inclined so as to gradually become higher toward the clamp mechanism 18 side, the clamp mechanism 18 side is gradually higher than the mounting portion 17, so that the disposable filter 24 is attached to the filter holding portion. When the filter holding unit 13 is rotated by setting it on the upper surface of the 13 mesh filters 15, the disposable filter 24 is less likely to be displaced on the upper surface of the mesh filter 15, and the disposable filter 24 can be securely attached.

As shown in FIG. 7, when it is inclined so as to be gradually lowered toward the clamp mechanism 18 side, the clamp mechanism 18 side is gradually lowered with respect to the mounting portion 17, so that the dust in the dust collecting container 11 When the filter holder 13 is rotated when discharging the filter from the opening 14, the disposable filter 24 can discharge the dust without being caught by the filter holder 13.

Next, a third embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the first embodiment and the second embodiment are denoted by the same reference numerals and description thereof is omitted.
The dust collecting container 29 of the third embodiment is provided with two filter holding portions.
Reference numeral 30 denotes a first filter holding portion that holds the mesh filter 15. The first rotation shaft 32 is inserted into the hole of the first attachment portion 31 and is rotatably mounted.
Reference numeral 33 denotes a first clamp mechanism that holds the first filter holding portion 30 in a closed state in the opening portion 14, and the first clamp mechanism 33 supports the first operation lever 34 and the first lever 34. The first support portion 35 and the first protrusion 6 with which the tip end portion 34a of the first operation lever 34 is engaged. As in the first embodiment, the disposable filter 24 is sandwiched between the opening 14 and the first filter holding unit 30 and can be attached to the dust collecting container 29.
Reference numeral 37 denotes a substantially rectangular connecting portion formed below the first filter holding portion 30 so that a second filter holding portion 38 to be described later can be attached.
Reference numeral 38 denotes a second filter holding portion for holding the urethane filter 16. The second rotation is inserted into the hole of the second mounting portion 39 provided at a position below the first mounting portion 31 on the front surface of the connecting portion 37. A shaft 40 is inserted, and is rotatably attached to the connecting portion 37.
Reference numeral 41 denotes a second clamp mechanism that holds the second filter holding portion 38 in a closed state in the opening portion of the connecting portion 37, and the second clamp mechanism 41 includes a second operation lever 42 and the connecting portion 37. The second support portion 43 is formed on the rear surface and supports the second lever 42, and the second protrusion 44 engages with the tip portion 42a of the second operation lever 42.
With the above configuration, when the dust accumulated in the dust collecting container 29 is discharged, as shown in FIG. 9, when the first clamp mechanism 33 is released, the first filter holding unit 30 rotates and the disposable filter 24 is rotated. At the same time, dust can be discharged from the opening 14.

By the way, if it is used for a long time, even if the disposable filter 24 is used, dust adheres to the urethane filter 16 and becomes clogged. When clogged, the air flow path becomes narrow and the suction work rate decreases, so that the urethane filter 16 needs to be maintained. When performing maintenance work, in the configuration of the first embodiment, the mesh filter 15 and the urethane filter 16 are held in one filter holding portion. Therefore, when removing the urethane filter 16, the mesh filter 15 is removed. It must be very inconvenient. However, in this embodiment, since the mesh filter 15 and the urethane filter 16 are held by the respective filter holding portions, when the urethane filter 16 is removed, it is only necessary to release the second clamping mechanism 41. Since it is good, the maintenance work of the said uretan filter 16 can be improved.
Next, a fourth embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the first to third embodiments are denoted by the same reference numerals and description thereof is omitted.
The dust collecting container 50 of the fourth embodiment is characterized by the position of the clamp mechanism 18, and as shown in FIG. 11, the clamp mechanism 18 is arranged on the insertion port 27 side, and the mounting portion 17 is stored in the storage. It is arranged on the back wall 28 side of the chamber 26. That is, the arrangement is the reverse of the arrangement of the first embodiment. In the configuration of the first embodiment, it is possible to prevent a part of the disposable filter 24 from protruding from the cleaner body 2, but since the clamp mechanism 18 is located above the communication port 9, the disposable filter 24. Depending on the mounting state, the communication port 9 may be closed with the disposable filter 14 that hangs down from the clamp mechanism 18. Therefore, by arranging the clamp mechanism 18 on the insertion port 27 side, the clamp mechanism 18 is positioned away from the communication port 9, so that the communication port 9 is defined by the disposable filter 24 that hangs down from the clamp mechanism 18. Can be blocked.
