Japanese Patent Laid-Open No. 2003-19094 JP 2005-152380 A

  The dust collected in the dust collecting container main body needs to be discarded in order to keep the electric blower exerting a predetermined suction force. In this case, it is desirable in terms of hygiene to dispose of the dust from the container main body without touching the dust.

  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 collecting container. 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, even if the discharge lid of the dust collecting container body is opened, a lump of dust may be caught inside the container body and the dust may not fall. In this case, it is necessary to scrape the dust caught inside the dust collecting container main body with a hand or a stick, which is not preferable because it is not a sanitary operation.

  Further, even if the discharge lid is provided with a discharge promotion member for scraping out the dust in the dust collecting container body in conjunction with the opening operation of the discharge lid, more dust is accumulated than the position where the discharge promotion member is located. In such a case, this lump of dust obstructs the movement of the discharge promoting member, and it becomes difficult to open the discharge lid. As a result, it is difficult to discharge dust. In addition, when dust enters the gap between the discharge promoting member and the dust collecting container, it is difficult to move the discharge promoting member, and it is difficult to open the discharge lid. Also in these cases, it is necessary to scrape the dust caught inside the dust collecting container main body with a hand or a stick, which is not preferable because it is not a sanitary operation.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an electric vacuum cleaner that can deal with the above-described problems, includes a dust container that can be taken in and out of a dust collection case, and can easily discharge dust accumulated in the dust container.

  The present invention relates to an electric vacuum cleaner having a dust collection case and a dust container that is provided in and out of the dust collection case, and the dust container expands when protruding from a loading / unloading opening of the dust collection case, It has a dust disposal port that narrows when returned to the dust collection case.

  According to the present invention, when the dust container protrudes from the entrance / exit opening of the dust collection case, the dust disposal port of the dust container expands, so that dust that is easily compressed and solidified due to an air flow such as fiber dust is collected. Even when dust is collected in the container, dust can be easily discharged.

  Embodiments of the present invention will be described with reference to the drawings.

  First, the outline of the vacuum cleaner will be described with reference to FIGS. 1, 2, and 3.

  The vacuum cleaner 1 has a main body case 2. The main body case 2 includes a lower main body case 3 and an upper main body case 4. The dust collection case 5 is detachably placed inside the front side of the main body case 2.

  The electric blower 6 is placed inside the rear side of the main body case 2. The dust removal unit 7 placed in the main body case 2 is located between the electric blower 6 and the dust collection case 5.

  As shown in FIGS. 1 and 2, the lid 8 is rotatably supported by the upper body case 4. Inside the front side of the main body case 2, there is a dust collection case storage portion 9 for storing the dust collection case 5.

  The dust collection case 5 is taken in and out by opening the lid 8 as shown in FIG. 2, and the lid 8 is closed during the cleaning operation.

  As shown in FIG. 1 and FIG. 5 to FIG. On the rear side of the dust collecting case 5, a filter unit 21 having a corrugated pleated filter is provided.

  As shown in FIG. 4, the filter unit 21 is provided to be openable and closable with respect to the dust collecting case 5. The lower part of the filter unit 21 is rotatably supported by a lower part of the dust collecting case 5 by a hinge 23, and the upper part is locked to a hook 22 provided on the upper part of the dust collecting case 5.

  When the hook 22 is removed with a finger, the filter unit 21 is opened with the lower hinge 23 as a fulcrum. It is also possible to provide the operation button dust collecting case 5 for operating the hook 22.

  The dust container 20 collects large coarse dust by filtration. Fine fine dust passes through the dust container 20 and is collected by filtration in the filter portion 21 of the dust collecting case 5.

  The dust removal unit 7 has a dust removal rotating body 24 as shown in FIG. The dust removing body 24 rotates when the power cord (not shown) wound around the cord reel (not shown) is unwound, vibrates the filter unit 21, and is collected by the filter unit 21. The fine dust thus removed is removed from the filter unit 21. The fine dust removed from the filter unit 21 is stored in a pocket 51 provided in the dust collecting case 5. The pocket 51 prevents the fine dust that has been removed from being scattered again and reattaching to the filter unit 21 when the air flow passes through the dust collecting case 5 by the operation of the vacuum cleaner. It is configured.

  The fine dust collected in the pocket 51 may be discarded by opening the filter unit 21 from the dust collecting case 5. At this time, the dust adhering to the filter portion 21 may be removed by brushing with a brush with a brush or by washing with water.

  The dust collected by the filter unit 21 is mostly fine dust. For this reason, there is also a feature that it is easy to remove fine dust by flipping the corrugated pleats of the filter unit 21.

  Next, the dust collection case 5 and the dust container 20 which are the main parts of the present invention will be described with reference to FIGS.

  The dust collection case 5 has a loading / unloading opening 25 in which the dust container 20 appears and disappears on the front side. The front lid 26 is rotatably provided on the front side of the dust collecting case 5 so as to open and close the opening / closing opening 25.

  The front lid 26 has an inlet 30 into which dust-containing air containing dust flows. The dust-containing air flows into the dust container 20 through the inlet 30. The inflow port 30 is provided with a check valve 31 that prevents the dust accumulated in the dust container 20 from flowing backward or preventing the sucked dust from spilling out of the dust collecting case 5.

  A lower portion of the front lid 26 is rotatably supported by a front lower portion on the outer peripheral side of the dust collecting case 5 by a hinge 27. A handle 28 extending in the front-rear direction is provided on the upper portion of the dust collection case 5. A clamp member 29 of front lid restraining means for restraining the front lid 26 closed on the distal end side of the handle 28 in a closed state is provided. A clamp member 29 is provided on the upper portion of the front lid 26, and front lid restraining means is provided by a locking groove 40 that engages with the clamp member 29.

  The front lid 26 is constrained in a closed state by the front lid restraining means, and the front lid 26 is opened so as to fall forward when the clamp member 29 is unlocked.

  The dust container 20 has at least two dust container parts 20A and 20B which are divided into upper and lower parts. Although the dust container 20 can be divided into left and right parts, here, description will be given along two dust container part pieces 20A and 20B which are divided into upper and lower parts.

  The upper dust container part 20A and the lower dust container part 20B are vertically joined together to form the dust container 20. The dust disposal port 202 is provided on the front side of the dust container 20. A hinge 203 is provided on the rear side / rear side of the dust container 20. The two dust container pieces 20A and 20B are connected and supported by the hinge 203 so as to be rotatable.

  The two dust container portions 20A and 20B that are rotatably supported by the hinge 203 can widen or narrow the dust disposal port 202. Further, the hinge 203 is provided with an opening biasing spring 204 as shown in FIG. The open biasing spring 204 is a helical spring or a leaf spring. When a helical spring is used as the opening biasing spring 204, it is desirable to support it through a support shaft (not shown) of the hinge 203.

  By this open biasing spring 204, the two dust container parts 20A and 20B are biased so as to expand the dust disposal port 202.

  The dust container 20 has a shape that narrows from the dust disposal port 202 toward the back side even when the two dust container parts 20A and 20B are combined.

  That is, the dust container 20 extends toward the dust disposal port 202. Moreover, when the accumulated dust is discarded, the two dust container parts 20A and 20B are opened so as to expand the dust disposal port 202.

  The dust container 20 includes a support frame 200 that maintains the outer shape, and a first filter 201 that is stretched on the support frame 200. The first filter 201 is composed of a mesh net filter, a wire net, a metal plate having a minute hole, a plastic plate having a minute hole, and the like. Collect by filtration.

  At this time, light and fluffy fiber dust such as cotton dust collected by the dust container 20 is likely to be compressed and compressed by the air flow passing through the dust container 20. Moreover, a part of the fine dust which flowed into the dust container 20 is also collected by the fiber dust which is compressed and solidified in the dust container 20. When the operation of the electric vacuum cleaner is stopped, the compressed dust lump loses the compressive force due to the air flow, the compressed dust lump spreads, and the dust lump volume increases.

  However, the dust container 20 is expanded toward the dust disposal port 202, and the two dust container parts 20A and 20B are opened so as to expand the dust disposal port 202 when the accumulated dust is discarded. Even when a mass of compressed dust stored in the dust container 20 spreads, it can be easily discharged from the dust disposal port 202.

  At this time, the dust sucked into the dust container 20 is likely to be compressed into a lump due to the air flow. Therefore, the dust is also discharged in a lump when discharged from the dust container 20 through the dust disposal port 202. The first filter 201 provided in the container 20 is less likely to be clogged with less dust adhesion and entanglement. For this reason, it is possible to prevent the dust collection net 201 from having to remove dust simply by throwing away the dust accumulated in the dust container 20. In addition, a part of fine dust such as dust that has flowed into the dust container 20 is also collected by the fiber dust compressed and solidified in the dust container 20, and the fiber dust wraps the fine dust. Therefore, when the dust accumulated in the dust container 20 is thrown away, the fine dust does not rise and is hygienic.

  In addition, since a part of fine dusts, such as the dust which flowed into the dust container 20, are also collected and the fiber dust wraps the fine dust, the 1st filter 201 provided in the dust container 20 by the fine dust is included. Since it is difficult to cause clogging of the vacuum cleaner, it is possible to suppress a decrease in the air flow when the vacuum cleaner is operated, and a decrease in the suction force can be suppressed, thereby suppressing a decrease in the ability to suck dust on the surface to be cleaned. Can do.

  Here, before attaching the dust collecting case 5 to the main body case 2, after putting the disposable dust collecting filter paper including dust paper into the recess of the dust container 20 with the front lid 26 opened, the front lid 26 is closed. The dust container 20 is pushed by the front lid 26 and disposed at a predetermined position in the dust collecting case 5. After this, if the dust collecting case 5 is attached to the main body case 2 and the electric vacuum cleaner 1 is operated for cleaning, the dust sucked into the dust container 20 is disposed upstream of the first filter 201. Most of the sucked dust is accumulated in the disposable dust collecting filter paper including the dust paper and on the upstream side thereof. In this state, the dust collecting case 5 will be described when it is taken out from the main body case 2 and the dust is discarded. Since the dust sucked into the dust container 20 tends to become a mass compressed by the air flow, it is wrapped in a disposable dust collecting filter paper including dust paper disposed upstream of the dust container 20 and in the recess of the dust container 20. In a rare state. For this reason, even when dust is discharged through the dust disposal port 202, most of the dust is discharged in the form of a lump wrapped in a disposable dust collecting filter paper including dust paper, so that the rise of fine dust does not occur. Hygienic.

  In the above, the disposable dust collecting filter paper including dust paper was attached by removing the dust collecting case 5 from the main body case 2, but the vacuum cleaner 1 is attached with the dust collecting case 5 attached to the main body case 2. It is also possible to operate and suck a disposable dust collecting filter paper containing dust paper from the tip of a hose (not shown) connected to the main body case 2 and place it in the recess of the dust container 20. Furthermore, the disposable vacuum cleaner 1 including the dust paper from the tip of a hose (not shown) connected to the main body case 2 is operated with the dust collection case 5 attached to the main body case 2 before throwing away the trash. It is also possible to discard the dust after sucking the filter paper and wrapping it with disposable dust collecting paper containing dust paper on both the upstream and downstream sides of the dust sucked and accumulated in the dust container 20.

  In this way, if a disposable dust collecting filter paper including dust paper is arranged on the upstream side of the first filter of the dust container 20, it is difficult for dust to adhere to the first filter and to prevent clogging of the first filter. Therefore, it is possible to prevent a decrease in suction force.

  Next, the lower dust container part piece 20 </ b> B is rotatably supported by a hinge 41 below the dust container part piece 20 </ b> B on the end side of the dust disposal port 202. The hinge 41 is located inside the collar portion 42 in which the entrance / exit opening 25 is formed in the dust collecting case 5.

  The hinge 41 and the hinge 27 of the front lid 26 are located on the front side of the dust collecting case 5 and are provided adjacent to each other. For this reason, the opening / closing operation | movement of the front cover 26 and the dust container part 20B is gathered together, and is performed smoothly.

  It should be noted that a hinge 27, which is a support portion for the front lid 26 that supports the front lid 26 so as to be opened and closed, is disposed on the outer peripheral portion of the dust collecting case 5, and a dust container part piece for supporting the dust container 20 so as to be opened and closed. A hinge 41 provided on 20B is provided inside the dust collecting case 5. Further, a hinge 41 that supports the dust container 20 so as to be opened and closed is disposed at a front portion of the dust container 20 at a position close to a hinge 27 that is a support portion for the front lid 26. Since it arrange | positions in this way, the airtight of the front cover 26 and the dust collecting case 5 should just provide the elastic body sealing member 52 attached to the front cover 26. FIG.

  Since this elastic seal member 52 does not need to straddle the hinge 27 that pivotally supports the front lid 26, the elastic seal 52 and the abutment portion 53 are provided when the dust collecting case 5 and the front lid 26 are airtight. Since it is configured on the same plane, it is easy to keep airtight. Furthermore, since the elastic seal member 52 can be configured not to span the hinge 41 that rotatably supports the dust container 20, the elastic seal member 52 is used when sealing between the front lid 26 and the dust container 20. The A contact portion 54 provided on the elastic body seal 52 and the dust container piece 20A and the B contact portion 55 provided on the elastic body seal 52 and the dust container portion piece 20B are configured on the same plane. So it is easy to be airtight. Further, the air seal between the front lid 26 and the dust collecting case 5 can be secured by one elastic body seal 52, and the air tightness of the dust container portion 20A constituting the front lid 26 and the dust container 20 can be secured. And airtightness of the dust container part 20B constituting the dust container 20 can be secured.

Further, since the contact portion with the elastic body seal 52 provided on the front lid 26 can be configured on the same plane, the force only in the direction in which the front lid 26 is urged toward the dust collecting case 5 is used. What is necessary is just to give between cases 5, and since it can be set as the structure which does not raise | generate an air leak easily, the fall of a suction work rate and the spill of garbage can be prevented. Furthermore, it is possible to prevent the dust flowing in from the inlet 30 from being short-circuited and flowing to the filter unit 21 without passing through the dust container 20.
Further, by making the contact point with the elastic seal 52 provided on the front lid 26 common on the same plane, there is no positional deviation between the front lid 26 and the dust container 20 during the opening / closing operation. The opening / closing operation of the front lid 26 and the dust container 20 is performed more smoothly.

  Here, as shown in FIG. 10, the protrusion biasing spring 43 is provided at the lower front side of the lower dust container piece 20B. The protrusion biasing spring 43 biases the lower dust container part 20 </ b> B so as to push it out of the dust collecting case 5.

  The protrusion biasing spring 43 is formed by a helical spring, one end is engaged with a spring locking portion 44 provided on the lower dust container portion 20B, and the other end is engaged with the dust collecting case 5. Yes. The protrusion biasing spring 43 applies a rotational force in a direction in which the lower dust container part 20 </ b> B protrudes from the dust collection case 5.

  Further, the upper dust container part 20A is slidably supported on the inner surface of the access opening 25, and the dust container part 20A slides while being slid by the slidable support. Operates to enter and exit. Since it is configured in this manner, by releasing the locking of the clamp member 29 that is constrained in the closed state of the front lid 26, the front lid 26 falls to the front side, and the two dust container parts 20A, dust The container piece 20 </ b> B is opened so as to expand the dust disposal port 202. In other words, the protrusion biasing spring 43 biases the dust container part 20B to push it out of the dust collecting case 5, and the two dust container parts 20A, the dust container so as to expand the dust disposal port 202. It is also possible to serve as a release biasing spring that opens the piece 20B.

  It should be noted that it is also possible to provide a projecting means that pushes the dust container portion outwardly by a motor or human operating force instead of the projecting biasing spring.

  The drop-off prevention member 45 of the drop-off prevention means is provided outside the upper dust container part 20A. The drop-off prevention member 45 is configured to contact the upper side of the flange portion 42 of the dust collection case 5. The drop-preventing member 45 comes into contact with the upper side of the flange portion 42, so that the upper dust container piece 20A is stopped. Since the upper dust container part 20A does not protrude further outward, the dust container part 20A and the dust container part 20B constituting the dust container 20 are expanded, and the dust disposal port 202 is expanded. The dust container 20 does not fall out of the dust collecting case 5.

  That is, in the dust container 20, the lower dust container part 20 </ b> B is rotatably supported by the dust collecting case 5 with a hinge 41, and the upper dust container part 20 </ b> A is slidable in and out of the opening / closing opening 25. Therefore, the dust container 20 is configured not to fall off from the dust collecting case 5.

  A force that always pushes the dust container 20 to the outside of the dust collecting case 5 by the protruding biasing spring 43 and the opening biasing spring 204 acts on the dust container 20. The front lid 26 stops the dust container 20 from protruding against the pushing force.

  Now, when the clamp member 29 of the restraining means for the front lid 26 is removed, the front lid 26 is opened so as to fall forward as shown in FIG. As shown in FIGS. 6 and 7, the dust container 20 that has been restrained by the front lid 26 protrudes out from the opening / closing opening of the dust collecting case 5.

  With this protrusion, the upper dust container part 20A and the lower dust container part 20B are opened, and the dust disposal port 202 is enlarged. The dust accumulated in the dust container 20 is discharged at once from the expanded dust disposal port 202.

  Moreover, the dust container 20 is suddenly stopped by the drop-off prevention means 45 when the dust container 20 protrudes out of the dust collecting case 5 by the protruding biasing spring 43 and the release biasing spring 204. Therefore, the first filter is caused by this impact. The dust adhering to the surface can be easily peeled off, and the dust can be further discharged from the dust container 20 and the first filter can be prevented from being clogged, so that the suction force can be prevented from being lowered.

  As shown in FIG. 4, the dust container 20 that has been disposed of is stored in a dust collection case 5. The enlarged dust disposal port 202 is narrowed and returned to the dust collection case 5.

  Storage of the dust container unit 20 is performed with the operation of closing the front lid 26. Since the hinge 27 that is the opening / closing axis of the front lid 26 and the hinge 41 that is the rotation axis of the dust container 20 are arranged in the lower part of the dust collecting case 5 in the same direction with respect to the dust collecting case 5, The rotation direction when opening and closing the lid 26 and the dust container 20 can be made the same, and the dust container 20 can be closed when the front lid 26 is closed.

  That is, the dust disposal port 202 that is placed forward together with the insertion / exit opening 25 faces the front lid 26. When the front lid 26 is closed, the inner surface side of the front lid 26 comes into contact with the dust disposal port 202 which is the front surface side of the dust container 20. The dust container portion 20 is pushed back by the front lid 26 and returned to the dust collecting case 5.

  The dust container 20 is pushed back against the protrusion biasing spring 43 and the opening biasing spring 204. The outer surface side of the upper dust container part 20 </ b> A is pushed and slid inside the opening / closing opening 25.

  For this reason, as the upper dust container part 20A enters the dust collecting case 5, it approaches the lower dust container part 20B and the dust disposal port 202 narrows. Thus, the dust container unit 20 is housed in the dust collection case 5.

  In this way, the dust container portion 20 can be easily put in and out by opening and closing the front lid 26. Moreover, since the dust container 20 can be taken in and out without touching the dust container part 20, it is convenient also in terms of hygiene.

  Maintenance of the dust container 20 is performed by taking it out from the dust collecting case 5 as shown in FIG. In the state shown in FIG. 7, the dust container part 20 can be removed from the collar part 42 by removing the upper dust container part 20 </ b> A downwardly and removed from the collar part 42. The removed dust container portion 20 can be easily maintained. In addition, the inside of the dust collecting case 5 can be easily cleaned.

  Moreover, as shown in FIG. 8, it is also possible to remove the filter part 21 from the dust collection case 5 and to carry out from the back side of the dust container 20. At this time, fine dust accumulated in the pocket 51 may be discarded.
