Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vacuum cleaner using a disposable dust collection bag.

[Prior art] In this type of vacuum cleaner, the dust collection bag is replaced at most once a month.
Spare dust collection bags should be stored in a separate storage area from the vacuum cleaner, or if the vacuum cleaner is equipped with an accessory storage case that the vacuum cleaner itself can be attached to and removed from,
It is designed to be stored in the storage space secured in this storage case.

[Problem that the invention attempts to solve]

However, in any case, to replace the dust collection bag, first remove the spare dust collection bag from the storage location, then open the lid that covers the opening of the dust collection chamber and remove the used dust collection bag. In the dust collection chamber with the dust bag removed,
A series of operations are required, including storing the spare dust collection bag, setting it in the suction port, and then closing the lid so that the set state is not damaged.

As described above, in the past, replacing the dust collection bag required a lot of effort and time, and replacing the dust collection bag was the most troublesome part of using a vacuum cleaner. and,
For this reason, a clogged dust collection bag is often continued to be used as it is, and in this case, not only is cleaning efficiency poor, but the load on the electric blower increases, which tends to shorten its life.

An object of the present invention is to provide a vacuum cleaner in which a disposable dust bag can be replaced extremely easily and reliably regardless of slight displacement of the dust bag.

[Means for solving problems]

The present invention includes a lid body rotatably attached to a vacuum cleaner body provided with a suction port, and the lid body opens and closes an opening of a dust collection chamber provided in the vacuum cleaner body, and also opens and closes an opening of a dust collection chamber provided in the vacuum cleaner body. A vacuum cleaner is provided with a pair of mouth frame holders provided on the side of the dust collection chamber, in which a mouth frame of a disposable dust collection bag that can be freely put in and taken out of the dust collection chamber is held in a detachable manner. Applicable. In order to achieve the above object, the vacuum cleaner of the present invention is provided with a plurality of spare dust collection bags that can be freely put in and taken out and arranged on the back side of the lid body, and opposite to the lid body. The front end of the bag storage body has a take-out opening in which the mouth frame holder is inserted and removed and the mouth frame of the spare dust collection bag is exposed on the side, and the front end of the bag storage body has a shaft on the front end side of the lid body. The interlocking mechanism is mounted rotatably through the shaft, and is provided in an interlocking mechanism that is operated by the lid to rotate the bag storage body toward the suction port when the lid is closed. a pinion to be rotated, and an interlocking body provided with an engagement rack on the front side of the pinion and a cam groove with an engagement part in the middle, so as to be able to reciprocate in the front-rear direction of the lid; One end is pivotally attached to the opening edge of the dust collection chamber, and a cam formed at the other end is slidably engaged with the cam groove, and when the lid is closed, a driving body that is operated by the cam to advance the interlocking body through engagement with the engaging portion of the cam; and a coil spring that is provided to constantly bias the interlocking body rearward and causes the interlocking body to retreat. The pair of mouth frame holders are each rotatably provided, and each is biased inwardly by a spring, and these mouth frame holders are temporarily held just before the lid closes. An opening frame holder drive mechanism is provided, and this drive mechanism is attached to a plate provided on the side of the dust collection chamber of the suction port so as to be able to move up and down, and its lower end is brought into contact with and separated from the upper edges of the pair of mouth frame holders. The drive unit of the mouth frame holder drive mechanism is formed by comprising an actuation body including a push plate having slanted portions on both sides, and a drive unit provided on the back surface of the lid body to move the actuation body up and down. An operating body for operating the lid is provided on the lid, and the operating portion is exposed to the outside of the lid.

[Effect]

According to the present invention, when the used dust collection bag is removed from the dust collection chamber, by operating the operation part of the operation body and then closing the lid, the rotation of the lid at this time is controlled. Accordingly, the bag storage body operates via an interlocking mechanism,
After being rotated toward the suction port, it is rotated to a position along the back surface of the lid. In other words, as the lid is closed, the cam slides on the cam groove and engages with the engaging part to push the interlocking body due to the displacement of the drive body that rotates with the lid, so this interlocking body is a coil It moves forward against the biasing force of the spring. This forward movement rotates the pinion via the rack, and at the same time, the bag storage body along the back surface of the lid rotates clockwise about the shaft. Due to this rotation, the bag storage body is rotated approximately 90 degrees until the lid is close to being fully closed, and is displaced to a substantially vertical position. In this manner, in a state where the bag storage body is rotated approximately 90 degrees from the position along the back surface of the lid body, the mouth frame holder is inserted into and removed from the removal opening. Through this insertion and removal, the mouth frame of the spare dust collection bag held in the bag storage body is engaged and held by the mouth frame holder, and then the dust collection bag is taken out from the take-out opening of the bag storage body and collected. It is set in a dust room. In this case, since the operating body is being operated as described above and the operating body is thereby displaced downward via the drive unit, the push plate of the operating body is tilted just before the lid closes. The shaped portion comes into contact with the upper edges of the pair of mouth frame holders and presses them. Therefore, the pair of mouth frame holders are pushed open by the slanted portions against the spring urging them. The pair of mouth frame holders are inserted into the take-out opening of the bag storage body in this open state. Therefore, even if a spare dust collection bag is stored in the bag storage body with some deviation and the position of its mouth frame is misaligned, the mouth frame will cross over the mouth frame holder regardless of this, and there will be a gap between the holders. Placed. In addition, the mouth frame holder drive mechanism is returned to its original position immediately before the lid is fully closed, that is, after the pair of mouth frame holders are temporarily opened as described above, and at the same time, the mouth frame holder drive mechanism is moved inward by the spring. The pair of biased spout holders return to their original positions, and these spout holders engage and hold the spout of the dust collection bag. Immediately after this, the cam is disengaged from the engagement portion and the action of the drive body to advance the interlocking body disappears, so the coil spring causes the interlocking body to retreat. For this reason, the bag storage body changes through changes in the meshing between the rack and pinion.
Rotate counterclockwise and return to the position along the back of the lid. Immediately after this, the lid body is fully closed.

The bag storage body 25 is rotatably mounted around the shaft 28 by having the shaft 28 penetrate and supported by a bearing portion 30 provided on the back plate 24. This bag storage body 2
5 stores a plurality of spare dust collection bags 5' that can be taken out and put in freely. The spare dust collection bag 5' has the same structure as the dust collection bag 5, and is stored and held in the bag storage body 25 with the opening frame 5a exposed to the removal opening 26 (see FIG. 7). It's getting old.
Note that 31 in FIG. 7 is a notch connected to the take-out opening 26, into which the mouth frame holder 9 is relatively inserted and removed as the bag storage body 25 rotates. Further, 25a is a knob.

Further, on the back side of the lid 13, an interlocking mechanism 32 is provided that makes use of the rotation when the lid 13 closes to rotate the bag storage body 25 back and forth once.
In this embodiment, the interlocking mechanism 32 includes an interlocking body 33, a rack 34, a coil spring 35, a driving member 36, a torsion spring 37, and a pinion 41, which will be described later. In other words, the interlocking body 33 is connected to the back plate 24.
It is located inside the back plate 24 and is movable approximately in the front-rear direction while being guided by a guide (not shown) on the back plate 24. The above-mentioned rack 34 is provided on the front side of the interlocking body 33, and a cam groove 38 is formed on the rear side. The cam groove 38 has a diagonal abutting part 38a as an engaging part in the middle to form a stepped shape, and has a locking groove part 38b at the rear end. The coil spring 35 is provided across the back plate 24 and the interlocking body 33, and always biases the interlocking body 33 toward the rear side. Therefore, the interlocking body 33 is prevented from moving backward by the back plate 24. The driving member 36 is rod-shaped, and one end is rotatably attached to a bearing 39 provided at the opening edge of the dust collection chamber 4, and the other end sliding portion 36a as a cam is attached to a cam groove 38. They are slidably engaged with each other. This member 36 is the bearing part 3
It is biased counterclockwise in the figure by a torsion spring 37 provided on the 9 side. The force of this spring 37 is smaller than the force of the torsion spring 15.

The interlocking mechanism 32 and the shaft 28 are connected via a clutch 40. As shown in FIGS. 8 and 9, the clutch 40 includes a driving clutch piece 41
and a driven clutch piece 42 that engages with the clutch by inserting and extracting, meshing, or frictionally engaging with the clutch. The driven clutch piece 42 is fixed to the shaft 28, and the central shaft 41a of the driving clutch piece 41 is slidably inserted into a central hole 28b protruding from the shaft 28. In this embodiment, the driving clutch piece 41 also serves as a pinion, and is meshed with the rack 34. A coil spring 43 is provided with both ends engaged with the mounting portion 27 and the driven clutch piece 42, and this spring 43 causes the driven clutch piece 42 to
is always maintained away from the drive clutch piece 41. In other words, with the above structure, the clutch 40 is always maintained in the disengaged state.

Further, an operating body 45 is provided on the lid 13 so that its operating portion faces outside the lid 13. This operating body 45 has a cam 46, and the cam 46 is sandwiched between the pair of shafts 28. The cam 46 has a substantially spindle-like planar shape, and the end of the shaft 28 is always in contact with the peripheral surface of the cam 46. The operating body 45 is biased in the direction around its axis by a spring 47, which causes the pair of shafts 2
Always operate the operating body 45 so that the distance between the axes of 8 is shortened.
is retained.

Furthermore, an actuating body 48 for opening the pair of mouth frame holders 9 is attached to the plate body 8 so as to be movable up and down, and a drive unit 49 for moving the actuating body 48 up and down is provided on the lid body 13. It is being The operating body 48 and the drive unit 49 cause the lid body 13 to
A mouth frame holder drive mechanism 50 is configured to temporarily open the mouth frame holder 9 immediately before closing.

That is, the actuating body 48 is formed by attaching a push plate 52 having slanted parts on both sides that contact the mouth frame holder 9 to the lower end of a push rod 51. This actuating body 48 is always urged upward by a spring 53, and the upper part of the push rod 51 projects from the plate body 8 toward the opening of the dust collection chamber 4. Therefore, the push rod 51 can be pressed with a finger when the lid 13 is open. Further, a release protrusion 54 is integrally provided at the upper end of the plate 8 near the upper side of the push rod 51 . The drive unit 49 attaches a drive body 57 to a shaft 56 installed between bearings 55 protruding from the back surface of the lid 13 so as to be rotatable and movable in the axial direction. A spring 58 urges the shaft 56 in the axial direction away from the push rod 51 . The driver 57 has an extending portion 57a that engages with the release protrusion 54, and a spring 58.
Due to the urging force, the actuating body 48 is always held in a position where it cannot press the push rod 51. Then, the driving body 57 is moved to a position where it can press the push rod 51 of the operating body 48 against the spring 58 by an interlocking part 59 made of a leaf spring that is protruded from the operating body 45. ing.

Next, the case where the dust collection bag 5 is replaced in the vacuum cleaner having the above structure will be explained.

The user first presses the clamp 17 to release the engagement between it and the clamp receiver 16. Then, the lid 13 automatically rotates and opens due to the force of the torsion spring 15. This state is shown in FIG. 1, and in this case, the bag storage body 25 is held in a position along the back surface of the lid body 13, and the sliding portion 36a is held in the locking groove portion 38b of the cam groove 38. It is located off the beaten path. Next, the user takes out the used dust collection bag 5 outside the dust collection chamber 4. Thereafter, the user rotates the operating body 45 approximately 90 degrees and holds it. Then, due to the rotation of the cam 46, the pair of shafts 28 are moved into the coil spring 4 so that the distance between the shafts becomes longer.
It is moved against the force of 3. Therefore, as shown in FIG. 9, the driven clutch piece 42 and the driving clutch piece 41 are engaged, and the clutch 40 is brought into a connected state. Then, while maintaining this state, the lid body 13
By closing the dust collection bag 5', the spare dust collection bag 5' can be automatically set in the dust collection chamber 4, and the replacement work is thus completed.

The automatic attachment of the spare dust collection bag 5' is shown in Figures 2 to 4.
The process shown in the figure is carried out. Figure 2 shows axis 1
The radius of rotation A of the contact portion 38a centered at 4, and the radius B of rotation of the sliding portion 36a centered around the bearing portion 39.
This shows the state at the time when the sliding portion 36a slides forward in the cam groove 38 and hits the contact portion 38a due to the difference between the two. From this point on, the interlocking body 33 is pushed forward by the drive member 36 against the force of the coil spring 35. Therefore, along with this, Rack 34
As a result, the clutch 40 including the driving clutch piece 41 which also serves as a pinion is rotated, and at the same time, the bag storage body 25 is rotated clockwise about the shaft 28. Then, just before the lid body 13 is completely closed, the bag storage body 25 is moved to the second position as shown in FIG.
The extraction opening 26 is rotated approximately 90 degrees from the state shown in the figure.
The opening frame 5a of the spare dust collection bag 5' exposed to the outside passes over the locking portion 9b of the opening frame holder 9. That is, relatively speaking, the mouth frame holder 9 is inserted into the extraction opening 26, and thereby the mouth frame 5a is engaged and held by the mouth frame holder 9.

By the way, in the above replacement procedure, the mouth frame holder drive mechanism 50 is operated. In other words, the operating body 4
5, the interlocking part 59 engages with the drive body 57, and the drive body 57 is moved against the spring 58 into the sixth position.
It is moved along the axis 56 in the direction of arrow C in the figure. Therefore, the lid 13 is closed while the driving body 57 is held in a position where it can press the actuating body 48. Therefore, when the bag storage body 25 rotates as described above and the mouth frame 5a approaches the suction port seal 7, the lower end of the driver 57 comes into contact with the upper end of the push rod 51 of the actuator 48. After this point, as the lid body 13 is further closed, the push rod 51 is pushed down via the drive body 57, so that the pair of mouth frame holders 9 are pushed open by the oblique portion of the push plate 52. In this state, the mouth frame holder 9 is inserted relatively into the take-out opening 26, so even if the position of the mouth frame 5a of the spare dust collection bag 5' in the bag storage body 25 is slightly shifted, the mouth frame holder 9
a can reliably get over the locking portion 9b of the mouth frame holder 9. Next, the mouth frame 5a is attached to the suction port seal 7.
After abutting against the release protrusion 54, the extending portion 57a of the driver 57 engages with the release protrusion 54. For this reason, a further lid body 1
3, the drive body 57 is rotated about the shaft 56 in the direction of arrow D in FIG. 6, so that the lower end of the drive body 57 comes off from the upper end of the push rod 51 just before the lid is completely closed. Then, since the actuating body 48 is pushed up by the spring 53, the pair of mouth frame holders 9 are rotated inwardly, and the locking portions 9b thereof are reliably engaged with the mouth frame 5a. Therefore, regardless of the slight positional deviation of the mouth frame 5a, the mouth frame holder drive mechanism 50
The above-mentioned automatic attachment is reliably carried out by this operation.

Immediately after the time shown in FIG. 3, the interlocking body 3
3's forward movement is restricted by hitting the back plate 24. Therefore, immediately after this point, the sliding portion 3 of the drive member 36
6a overcomes the contact portion 38a. Therefore, since the driving member 36 is pulled back by the force of the coil spring 35, the bag storage body 25 is rotated counterclockwise due to the engagement between the rack 34 and the driving clutch piece 41 which also serves as a pinion of the clutch 40. and is returned to a position along the back surface of the lid body 13. At this time, the mouth plate 5a is engaged and held by the mouth frame holder 9, so the spare dust collection bag 5' is taken out from the take-out opening 26 of the bag storage body 25 and placed in the dust collection chamber 24. is set to Immediately after this, clamp receiver 1
6 and the clamp 17 are engaged, and the lid body 13
is held closed. This condition is shown in FIG.

After the above procedure, the user releases the operating body 45 by the force of the spring 47.
When the driven clutch pieces 42 are rotated back to their original positions, the force of the coil springs 43 causes the driven clutch pieces 42 to return to their original positions. This condition is shown in FIG. 8, with clutch 40 remaining in the disengaged condition.

In this embodiment, when taking out the used dust collection bag 5 from the dust collection chamber 4, the push rod 51 can be pressed with a finger. This allows the pair of mouth frame holders 9 to be opened and the used dust collection bag to be easily taken out.

Furthermore, since the clutch 40 remains in the disengaged state unless the operating body 45 is turned approximately 90 degrees, the clutch 40 is disengaged during normal use of the vacuum cleaner. Therefore, even if the lid 13 is simply opened or closed during use, the bag storage body 25 will not be rotated by the interlocking mechanism 32. Therefore, it is possible to check whether the dust collection bag 5 is clogged with garbage during use, or to take measures to collect coins, etc. that have been accidentally sucked in from inside the dust collection bag 5. There is no problem with automatic replacement.

In this embodiment, since the lid body 13 is provided with the see-through member 20, the bag storage body 25 can be viewed from the outside.
By visually checking, it is possible to easily know whether or not a spare dust collection bag 5' is stored in the bag storage body 25. Therefore, it is possible to know when to replenish the spare dust collection bag 5'. Then, insert the spare dust collection bag 5' into the bag storage body 25.
To replenish the bag, first open the lid 13, then grasp the knob 25a and rotate the bag storage body 25 approximately 90 degrees as shown in FIG. Then, since the interlocking body 33 is moved forward, when the sliding part 36a and the locking groove part 38b face each other, the sliding part 36a enters into the locking groove part 38b by the force of the torsion spring 37 and is engaged with the sliding part 36a. . Therefore, the bag storage body 25 is fixed with the take-out opening 26 facing upward. Therefore, in this state, the spare dust collection bag 5' is inserted into the bag storage body 2.
5 through the take-out opening 26 or the like. In this way, the bag storage body 25 can be fixed without manual effort, making replenishment work easier. After replenishment, the bag storage body 25 can be returned to its original position by manually rotating the driving member 36 a little to disengage the sliding portion 36a from the locking groove portion 38b.

In addition, in the above-mentioned embodiment, the vacuum cleaner body 1 is constructed by assembling a pair of upper and lower or left and right case components, but in the present invention, the vacuum cleaner body 1 has a structure in which a dust collection case is detachably connected to the front side of the main body case. It may be. In the above embodiment, the torsion spring 37 urges the drive member 36 counterclockwise, but even if the cam groove 38 does not have the locking groove part or has the locking groove part 38b, this groove part If 38b is provided in the opposite direction to that in the above embodiment, the torsion spring 37 may bias the drive member 36 clockwise. Furthermore, the transparent member 20 may be omitted.

In addition, when implementing this invention, unless it is contrary to the gist of the invention, the vacuum cleaner body, suction port, lid body, dust collection chamber, mouth frame holder, bag storage body, interlocking mechanism, take-out opening, dust collection bag. The specific structure, shape, position, material, etc. of the mouth frame, clutch, operating body, mouth frame holder drive mechanism, etc. are not limited to the above-mentioned embodiment, and can be configured and implemented in various ways. Of course.

[Effect of idea]

Since the gist of the present invention described above is the structure described in the scope of the above-mentioned utility model registration claim, only when the extra disposable dust collection bag stored on the back side of the lid is connected to the clutch. It can be installed automatically by closing the lid. In addition, since a mouth frame holder drive mechanism linked to the operating body is provided to temporarily open the pair of mouth frame holders, even if the spare dust collection bag inside the bag storage body is slightly misaligned, This has the effect of automatically attaching the dust collection bag reliably.
