Description

  The present invention relates to a vacuum cleaner.

  A vacuum cleaner for making the dust collection bag and the dust collected in the dust collection bag hygienic is described in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 7-10086).

  The vacuum cleaner disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 7-10086) is configured such that a shielding plate is slidably disposed on the front surface of the support plate of the dust collecting bag, so that the bag can be removed from the dust suction port of the support plate when throwing away the garbage. The suction port can be closed on the side of the body.

Japanese Patent Laid-Open No. 7-100086

  The dust collected in the dust bag must be discarded periodically to keep the electric blower exerting the specified suction force, and when the suction force is reduced, it can be easily touched without touching the dust. It is desirable in terms of hygiene that the dust bag can be taken out without being spilled from the dust bag.

  Further, while the vacuum cleaner is in operation, light and fluffy fiber dust such as cotton dust tends to become a compressed mass due to the air flow passing through the dust bag. However, when the operation of the vacuum cleaner is stopped, the compressive force due to the air flow is lost, the compressed dust mass spreads, and the dust mass volume increases. For this reason, when a large amount of dust is sucked into the dust collection bag, the dust may accumulate up to the vicinity of the opening provided in the mouth plate.

  In the invention shown in Patent Document 1, it is proposed that a shielding plate is slidably disposed on the front surface of the support plate of the dust bag. In this case, the opening provided by the shielding plate on the support plate is proposed. Since it moves substantially parallel to the surface, there is a problem in that dust accumulated near the opening obstructs the shield plate and cannot be covered.

  In addition, if a force is applied forcefully in this state to close the shielding plate, there is a problem that dust accumulated in the vicinity of the opening spills, which is not preferable because it is not a sanitary operation.

  An object of the present invention is to solve the above-described problem, and to provide a vacuum cleaner that can easily and hygienly discard collected dust.

  In order to achieve the above object, the present invention is characterized by comprising a vacuum cleaner body having a dust collector and an electric blower, and a dust bag attached to the dust collector, the dust bag being opened. And a bag member attached to the mouth plate, and a rotating shaft and a holder are provided below the dust collecting portion, and the holder uses the rotating shaft as a rotating shaft. It is inclined to the electric blower side, and the mouth plate can be attached to the holder.

Here, the elastic seal member integrated with the check valve 31 is in an airtight state against the mouth plate 22 provided in the dust bag 20 and has an action of preventing dust from spilling.

  Next, the arrangement inside the cleaner body 2 will be described. The hose connection port 10 is located at the center in the width direction of the cleaner body 2 when viewed from above, and is disposed on the front surface of the cleaner body 2. Similarly, the opening 26 which is the inflow portion of the dust collection bag 20 is located at the center in the width direction of the dust collection portion 5 and is disposed in front of the dust collection portion 5. Since it arrange | positions in this way, since it is not necessary to provide a curvature etc. in the entrance part of the dust collection part 5, the effect which can make ventilation loss small is acquired.

  Next, the dust collecting unit 5 will be described with reference to FIGS. 1 and 3 to 9. FIG. 4 is an enlarged view of a portion A in FIG. FIG. 5 is a perspective view of a dust bag showing an embodiment of the present invention. FIG. 6 is a partial central longitudinal sectional view of the cleaner body when the lid is opened and the dust bag is attached to the holder according to one embodiment of the present invention. FIG. 7 is a partial central longitudinal sectional view of the vacuum cleaner main body when the lid is opened and the dust bag is discarded according to an embodiment of the present invention. FIG. 8 is a perspective view when the dust bag showing one embodiment of the present invention is discarded. FIG. 9 is a central longitudinal sectional view of a cleaner body showing one embodiment of the present invention.

  As shown in FIGS. 1, 3, and 4, the dust collecting unit 5 includes a space surrounded by the lower main body case 3, the upper main body case 4, and the lid 8. As shown in FIG. 5, the dust bag 20 is a bag member 21 made of paper, cloth, non-woven fabric such as animal hair or plastic material, and a mouth plate made of cardboard or plastic having an opening 26. 22. The dust collection bag 20 is detachably attached to a holder 36 provided in the dust collection unit 5.

  When the mouth plate 22 is held by a locking portion 38 provided on the clamp 28 and the lid 8 is closed, the reinforcing portion 33 provided on the clamp 28 is locked by a rib 34 provided on the lid 8. For this reason, even when the electric blower 9 is driven in a state where dust is accumulated in the dust collection bag 20, the dust collection bag 20 is pulled toward the electric blower 9, and the mouth plate 22 is integrated with the check valve 31. It is possible to prevent separation from the elastic seal member and to prevent dust from spilling. The check valve 31 functions to prevent the dust accumulated in the dust bag 20 from the opening 26 provided in the dust bag 20 from flowing back to the connecting portion 12 a provided in the hose 12.

  In addition, the dust bag 20 includes a seal member 23 that closes the opening 26 provided in the mouth plate 22 when the dust bag 20 is discarded after the dust bag 20 accumulates dust. The seal member 23 includes a seal portion 24 and a release paper 25 that covers the adhesive surface of the seal portion. Note that a locking hole 27 is formed at the tip of the release paper 25 to be hooked on the engaging portion 17 and locked.

  In order to attach the dust bag 20 to the dust collecting unit 5 in the cleaner body 2, as shown in FIG. 6, the dust bag is placed on the holder 36 inclined to the electric blower 9 side with the rotating shaft 37 as the rotating shaft. The 20 mouth plates 22 are attached, the mouth plate 22 and the holder 36 are raised, and the engaging portion 38 provided on the clamp 28 is hooked on the mouth plate 22 and attached. The clamp 28 can be easily attached to the dust bag 20 if the rotation shaft 35 is rotatable about the rotation shaft.

  Next, the locking hole 27 provided in the release paper 25 is hooked on the engaging portion 17. Here, when the dust collection bag 20 is attached to the dust collection unit 5, the seal member 23 is disposed between the lid 8 and the bag member 21 of the dust collection bag 20. For this reason, the locking hole 27 and the engaging part 17 provided in the release paper 25 can be visually confirmed, and the locking hole 27 can be easily attached. In addition, if this engaging part 17 is arrange | positioned above the mouthplate 22 in the upper part of the clamp 28 or the dust collection part 5 as shown in the figure, the latching hole 27 will be made into the engaging part 17. Since it is easy to attach, it is more preferable.

  Further, the engaging portion 17 and the locking hole 27 are not wide in the width direction of the mouth plate 22, but are provided in the vicinity of the center in the width direction of the mouth plate 22 here. On the other hand, the hook 29 provided on the clamp 28, the reinforcing portion 33, and the rib 39 provided on the lid 8 are not provided near the center in the width direction of the mouth plate 22, but near both ends in the width direction of the mouth plate 22. Provided. Therefore, when the locking hole 27 is attached to the engaging portion 17 and the lid 8 is closed, the release paper 25 can be prevented from being cut by being sandwiched between the rib 39 and the clamp 28.

  The dust bag 20 is configured by joining a bag member 21 to one surface (back surface) of a mouth plate 22 having an opening 26. As shown in FIG. 5, the bag member 21 joined to the mouth plate 22 is folded at folds 21 a and 21 b and is folded at the back side of the mouth plate 22. The mouth plate 22 is formed with a protruding portion 22 a that protrudes from a joint portion (fold 21 a) with the bag member 21. The seal member 23 is attached to the back side of the protruding portion 22a. For this reason, when the dust bag 20 is attached, it is possible to prevent the seal member 23 from being cut by being sandwiched between the holder 36 and the mouth plate 22.

  Next, the case where the dust bag 20 is discarded by sucking dust will be described. When the lid 8 is opened and tilted to the front side (left side in FIG. 7) of the reinforcing portion 33, the hook 29, or the engaging portion 17, the locking portion 38 is detached from the mouth plate 22, and the holder with the rotating shaft 37 as the rotating shaft. 36 and the mouth plate 22 fall to the electric blower 9 side. Since the mouth plate 22 moves away from the engaging portion 17, the release paper 25 starts to peel off from the seal portion 24. Then, as the mouth plate 22 is pulled out from the holder 36, the release paper 25 is peeled off from the seal portion 24. At this time, since the engaging hole 17 of the release paper 25 which is one end of the seal member 23 is pulled by the engaging portion 17, when the mouth plate 22 is pulled out, the adhesive surface of the seal portion 24 opens the opening of the mouth plate 22. The dust bag 20 can be taken out so as to block the portion 26. Note that it is more preferable that the engaging portion 17 be a saddle shape convex to the front side (left side in FIG. 4), since the locking hole 27 is difficult to be detached from the engaging portion 17 when the dust bag 20 is taken out. .

  Here, when the dust bag 20 is taken out from the dust collecting portion 5, as shown in FIG. 8, the seal portion 24 closes the opening 26 and can be taken out. That is, if the operation of taking out the dust bag 20 from the dust collector 5 is performed, the opening 26 of the mouth plate 22 can be closed, so that the dust bag 20 can be easily taken out without touching the dust, and the dust bag. Since it can be thrown away without spilling dust from 20, it is hygienic. If the seal portion 24 is pressed against the mouth plate 22 after the dust bag 20 is taken out of the dust collection portion 5, the adhesion between the seal portion 24 and the mouth plate 22 is improved, so that dust spills from the opening portion 26. Can be prevented more.

  In addition, after the opening portion 26 of the mouth plate 22 is closed by the seal portion 24, when the dust collection bag 20 is pulled out from the dust collection portion 5, even if the locking hole 27 is caught by the engagement portion 17 and is torn, it is collected. The dust bag 20 may be discarded.

  Light and fluffy fiber dust such as cotton dust collected by the dust bag 20 tends to be compressed by the air flow passing through the dust bag 20. When the operation of the electric vacuum cleaner 1 is stopped, the compressed dust lump loses the compressive force due to the air flow, the compressed dust lump expands, the dust lump volume increases, and the opening of the mouth plate 22 increases. In some cases, the unit 26 overflows. Here, the seal portion 24 according to the present invention does not move parallel to the surface of the mouth plate 22. That is, the opening 26 is closed from the upper front side of the mouth plate 22 instead of sealing with an operation like a shutter. For this reason, even when the dust is collected in the vicinity of the opening 26, the opening 26 can be sealed, and the dust can be disposed of in a sanitary manner.

  In addition, the operation | movement which takes out the above dust collection bag 20 from the dust collection part 5 is the state which stood the vacuum cleaner main body 2 which turned down the front side (left side shown in FIG. 7) and the back side (right side shown in FIG. 7). In this case, even when dust is accumulated in the vicinity of the opening 26, it is difficult for the dust to spill, and it is possible to dispose of dust more preferably for hygiene purposes.

  As shown in FIGS. 3 and 4, in this embodiment, the seal member 23 provided in the dust bag 20 is not attached to the bag member 21, which is a flow path through which air passes, and the back surface of the mouth plate 22. Since it is attached to the electric blower 9 side which is the side, the flow passage area of the bag member 21 is not reduced. That is, it is possible to prevent the increase in pressure loss due to the air flow and to sanitize the dust bag 20 without reducing the suction work rate.

  Here, the seal member 23 includes a seal portion 24 and a release paper 25, and the seal portion 24 is disposed between the release paper 25 and the bag member 21. That is, in the state shown in FIGS. 3 to 7, the release paper 25, the seal portion 24, and the bag member 21 are arranged in this order from the top. That is, the engagement hole 27 side, which is the tip of the release paper 25, is disposed on the front side (upstream side, left side in FIG. 3) of the mouth plate 22, and the mouth plate 22 is pulled up or the release paper 25 is pulled down. When the operation is performed, the opening 26 of the mouth plate 22 can be easily sealed.

  In this embodiment, in order to suck the dust and suppress the reduction of the suction force due to the clogging of the dust bag 20, the dust removal unit 7 is mounted and the dust adhered to the bag member 21 of the dust bag 20 is removed. It is made to peel and the clogging of the dust bag 20 is suppressed. The opening 26 of the dust bag 20 is closed and discarded so that the dust that has been removed does not spill when the dust bag 20 is discarded, which is advantageous in terms of hygiene. That is, it is possible to carry out both the maintenance of the suction force and the sanitary disposal of the sucked dust.

  Here, when it is not desired to seal the opening 26 of the dust bag 20 when, for example, something other than dust is sucked by mistake, the locking hole 27 provided in the sealing member 23 is removed from the engaging portion 17. The dust collection bag 20 may be removed from the dust collection unit 5. In this way, it is possible to take out anything other than dust by mistake in the dust bag 20. After this, if the dust bag 20 is attached to the dust collector 5 again and the locking hole 27 is locked to the engaging portion 17, the opening 26 can be sealed when the dust bag 20 is discarded. Is possible.

  Further, in this embodiment, the mouth plate 22 of the dust bag 20 is attached to the holder 36, and the locking portion 38 sandwiches the mouth plate 22, so that the clamp 28 is disposed at a predetermined position. For this reason, as shown in FIG. 9, when the locking portion 38 does not sandwich the mouth plate 22, the clamp 28 is inclined to the electric blower 9 side with the rotation shaft 35 as the rotation center, and is provided on the lid 8. The rib 39 hits the reinforcing portion 33 and the lid 8 is not completely closed. Since it is set as such a structure, when the dust bag 20 is not mounted | worn in the predetermined position, a user is alerted by the lid 8 not closing. Even in this case, since the ribs 34 and the ribs 39 provided on the lid 8 are arranged so as not to sandwich the release paper 25, there is no inconvenience that the release paper 25 is cut.

  Next, the seal member 23 provided in the dust bag 20 will be described with reference to FIGS. 4 and 10 to 13.

  FIG. 10 is a plan view of a seal member showing an embodiment of the present invention. 11 is a cross-sectional view taken along the line BB in FIG. 12 is a cross-sectional view taken along the line CC of FIG. FIG. 13 is an enlarged view of a portion D in FIG. FIG. 14 is an enlarged view of a portion E in FIG.

  The seal member 23 includes a seal portion 24 having glue 41 and a release paper 25. Since this sealing member 23 can be punched into the shape shown in FIG. Then, as shown in the B-B cross section (FIG. 11), the glue 41 of the seal portion 24 of the attachment portion 44 is removed as shown in FIG. It is good to affix the back (downstream) of the. Here, when the opening 26 of the mouth plate 22 is sealed, the sealing member 23 is pulled in the upward direction in FIG. 4, the left side in FIG. 4 across the top of the mouth plate 22, and the mouth plate 22. 4 is the lower direction of FIG. That is, since the seal member 23 is not pulled in the downstream direction (the right side in FIG. 4) of the mouth plate 22 that is the direction in which the attachment portion 44 is peeled off, it is not necessary to sew the attachment portion 44 to the mouth plate 22. It can be created at low cost.

  Further, as shown in the CC cross section of FIG. 12, the locking hole 27 may be punched at the same time when the seal member 23 is punched with a punching die so as to penetrate from the release paper 25 to the seal portion 24. At this time, as shown in FIG. 13, a cut 42 is made only in the release paper 25 in the BB cross section. Further, as shown in FIG. 14, a cut 43 is made in the seal portion 24 and the glue 41 in the CC cross section. Since there are such notches 42 and 43, when the locking hole 27 is fixed and the mouth plate 22 is pulled out from the dust collecting portion 5, the paste 41 and the release paper 25 of the seal portion 24 are peeled off. In the vicinity of the recess between the BB cross section and the CC cross section shown in FIG. 10, the release paper 25 is peeled off without tearing the seal portion 24, and the opening 26 of the mouth plate 22 can be easily covered with the seal portion 24. is there. At this time, the seal portion 24 of the convex portion on the left side of the center in FIG. 10 (the left portion from the dotted line of the CC cross section) is cut off from the right side from the dotted line of the CC cross section, and the release paper 25 as shown in FIG. It remains in the state. If it does in this way, since the release paper 25 can be discarded simultaneously with the dust bag 20, it is more preferable because it saves labor. It should be noted that the seal portion 24 and the release paper 25 may be prevented from being peeled off at either or both of the right end portions of FIGS. 11 and 12, and the seal member 23 may be made longer than the longitudinal length of the mouth plate 22. This is preferable because the release paper 25 can easily remain on the seal member 23.

  Here, in the state where the seal member 23 is attached to the mouth plate 22 of the dust collection bag 20, the glue 41 of the seal portion 24 is not exposed except for a minute gap portion of the notch 42. Therefore, the dust collection bag 20 , It can be prevented from adhering to the bag member 21 or the dust collecting part 5, which is preferable in terms of handling.

  Further, in this embodiment, the vicinity of the locking hole 27 is attached to the engaging portion 17 with both the seal portion 24 and the release paper 25 left, but this portion of the seal portion 24 is used to block the mouth plate 22. Is not used. For this reason, the convex part on the left side of the center in FIG. 10 (the part on the left side of the dotted line in the CC section) may be the release paper 25 only, and the seal part 24 and the glue 41 may be removed.

  In this embodiment, the dust collecting bag 20 is collected by hooking a locking hole 27 arranged at the end of the release paper 25 provided in the sealing member 23 to the protruding engaging portion 17 provided in the clamp 28. Although attached to the part 5, the end of the release paper 25 may be sandwiched between clip-like engaging parts provided in the dust collecting part 5. In this case, when the dust collection bag 20 is taken out from the dust collection portion 5, if a clip having a spring force that allows the release paper 25 to be detached from the clip-like engagement portion is used as the engagement portion, the user's handleability is improved. improves.
