TITLE OF THE IMVENTION
HAND-HELD VACUUM CLEANER
FIELD OF THE INVENTION
The present invention relates to a hand-held elec-tric vacuum cleaner, and more particularly to such a cleaner which is suited to clean places of small space or a special place remote from wall outlets rather than entirely clean roorns or wide places.
RELATED ART STATEMENT
. Unexamined Japanese Utility Model Publication SHO
58-160555, for example, discloses a cordless hand-held vacuum cleaner of the above-rnentioned type which comprises a dust case attached to the front of its main body a-nd having a specific filter device therein. The cleaner is inconvenient to handle since the filter device needs to be cleaned every time dirt is discarded, while the cleaner requires the filter device which is specifically designed therefor.
Accordingly, one of the present inventors has al-ready proposed a hand-held vacuum cleaner adapted for use with a paper filter, such as tissue paper or kitchen paper, which is inexpensive and readily available (see Japanese Utility Model Application SHO 59-168191). This cleaner is provided with a dust collecting recess formed in the front .: ~
'7SiO
portion of its main body and having an upward opening. A
paper filter is placed into the recess, which is then closed over the paper fllter with a closure having a suction open-ing. Thus, dirt can be collected in the recess by the filter.
The collected dirt can be discarded easily along with the filter by removing from the recess the paper filter with the accumulation of dirt thereon.
Although the vacuum cleaner is thus made easy to handle, the cleaner still has the problem that the dirt once collected is liable to spill when it is to be discarded. Stated more specifically, the closure must be opened first before the paper filter is removed from the recess with the dirt collected thereon. However, when the closure is opened, the dirt collecting portion of the paper filter is exposed to readily permit spilling of the dirt, while the exposed dirt collecting portion is urged by the opening of the closure to release the dirt easily.
Another problem is encountered with the hand-held vacuum cleaner for which a paper filter is usable.
Fig. 6 shows such a cleaner which has a dust collecting recess 40 formed in the front portion of its main body, a closure 41 for the recess and a paper filter 42 provided between the recessed portion and the closure. The cleaner has the drawback that the margin 42a of the paper filter 42 ., .
O
fitted in place is left projec~ing from the closure 41, is there-fore unsightly and is likely to become soiled or broken.
The present invention provides a hand-held vacuum cleaner, comprising a main body having a dust collecting recess in a front portion thereof, an air outlet communicating with the recess, said dust collecting recess having an upward opening, a handle, a dust case having an upward opening and an air permeable filter wall formed as at least a portion of its structural wall, the dust case being removably fitted within the dust collecting recess, a partitioning member having a suction opening and remov-ably fitted over the opening of the dust case to cover the open-ing, a closure pivoted to the main body for opening and closing the opening of the dust collecting recesses except the suction opening of the partitioning member, a fan motor positioned in the main body for drawing in outside air through the suction opening and discharging the air from the air outlet at least through the filter wall, means for supplying electric power to a fan motor, said partitioning member comprising a base plate removably fitted over the upward opening of the dust case for covering the opening and for holding a thin filter between the base plate and the dust case, and the base plate having the suction opening and ribs extending longitudinally of the vacuum cleaner and downwardly from its reverse side to substantially an inside surface of the dust case for contacting and pushing the thin filter into the dust case. Suitably the partitioning member comprises a base plate removably fitted over the upward opening of the dust case to cover the opening, and the base plate has the suction opening and ribs extending downward from its reverse side. Desirably each of the ribs of the partitioning member has a cutout for passing therethrough the outside air drawn in.
In one embodiment of the present invention the dust case is provided at lts opening peripheral edge with a packing frame clamped between the opening peripheral edge of the dust collecting recessed portion and the closure. Suitably the pack-:1~ 6'~
ing frame has posltioning lugs extending outward therefrom overthe opening peripheral edge of the dust collecting recessed por-tion. Preferably the closure has a side plate downwardly extend-ing from its side edge, and the positioning lug of the packing frame is held between the side plate and the opening peripheral edge of the dust collecting recessed portion. Suitably the power supplying means comprises a power supply battery housed in a reverse portion of the main body and a power supply circuit for supplying electric power from the battery to the fan motor via a power supply switch.

According to the present invention, the parti-tioning member provided for removably covering the upward opening of the dust case ma~es it possible to remove the dust case first in a closed state from the dust collecting recess of the main body (irrespective of whether a paper filter is used or not), so that the collected dirt can be carried, as confined in the compacted case, to a location very close to the place of dirt disposal without being released from the case before approaching the place of disposal. Thus, the present invention precludes spilling of dirt when the cleaner is emptied of dirt and assures facilitated disposal of dirt.
Further when the vacuum cleaner of the present invention has paper holding ribs formed on the partition-ing member which is more specifically a filter holder, a paper filter can be held between the holder and the dust case, as extended over the inside surface of the dust case by the holder, especially by the paper holding ribs there-of, consequently affording a wide dust collecting space.
Moreover, if the margin of the paper filter pro~ects upward outside the filter holder, the margin is folded over, and the upward opening of the dust collecting recess is then l~t~ ~jt~
closed with the clos~re. The margin of the filter is therefore covered with the closure without projectlng out.
The dust or dirt drawn in through the suction openins accumvlates on the filter paper and can be dlscardec along with the filter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to Figs. 1 to 4 first, the main body 1 of a hand-held electric vacuum cleaner has at its reverse portion a device accommodating portion 6 housing a fan motor 2, a power supply switch 3a, rechargeable batteries 4 and like electric devices and provided with 1~7~ ~0 a handle 5. The main body 1 is formed in its front portion with a dust collecting recess 9 communicating with the devlce accommodatlng portion 6 through a suction opening 7 and havlng an upward openlng 8. The recessed portion has a first opening 8a at its front end for a suction opening member to fit in. The recess 9 is defined by an upper side wall 10 and a lower side wall 11, the former being positioned inwardly of the latter toward the center of the recess 9. The junctior. between the upper and lower side walls 10 and 11 is stepped and formed with a groove 12 for a closure 13 to engage in. Indicated at la are air discharge ports, and at 3 is a power supply circuit including the switch 3a.
The closure 13 for openably closing the upward opening 8 of the dust collecting recess 9 is pivotably attached by hinge means 14 to the wall of the main body 1 above the suction opening 7 in the main body 1. The closure 13 has opposite side plates 15 downwardly extending from its top plate for covering the uppwer side wall 10 with their lower ends engaged in the groove 12 wher. the closure 13 closes the upward opening 8. The closure 13 is provided with a generally inverted ~-shaped latch member 18 of synthetic resin engaging in latch holes 16 in the main body 1 at all times when the closure 13 is in its closed position to hold the closure closed. When a button '7~-iO
17 projecting outward from the side plate 15 is depressed, the latch member 18 lS released from the hole 16 by being bent to make the closure 13 openable.
A dust case 19, which is removably fitted in the recess 9, has an upward opening 20 and is formed at its front end with a second opening 20a for the suction opening member to fit in. The dust case 19 comprises a box-shaped mesh filter portion 21 accommodated in the recess 9 and spaced from the inner surface of the recessed portion, and a packing frame 24 of flexible synthetic resin generally identical in configuration with the upward opening edge 22 of the recessed portion 9. When the closure 13 is closed, the packing frame 24 is pressed on by a ridge 23 on the closure 13 and held between the opening edge 22 and the closure 13. The packing frame 24 has on its inner side a ring-like downward extension 25 extending into the recess 9 inside the opening edge 22 and having the opening edge of the mesh filter portion 21 attached thereto. Lugs 26, 26 are provided on the outer side of the packing frame 24 at opposite side portions thereof. When the dust case 19 is placed in the dust collecting recess 9, each of the lugs 26 is positioned outside the upward opening edge 22, held between the upper side wall 10 and the downward extension 18 of the closure 13 and covered with the closure 25 13. Accordingly, the lugs 26 hold the packing frame 24 ...:
:.,.. ~: .-.
.
1,4ti ~ ~3 1() accurately ln position over the openin~ edge 22, consequently holding the dust case 19 ln place wlthin the recess 9 without allowing deformation of the case. ~urther the dust case 19 can be withdrawn from the recess 9 by pulling out the lugs 26 with fingers.
The dust case 19 is provlded wlth a filter holder 27 serving as a partitioning member. The filter holder 27 comprises a base plate 28 covering the upward opening 20 of the dust case 19 and a pair of paper holding ribs 29, 29 extending from the reverse side of the base plate 28 downward into the dust case 19 and also extending longitudinally of the cleaner. Each of the paper holding ribs 29 is formed with an upward cutout 29a in the lower end of its midportion for passing suction air therethrough. Guide ribs 29b extend from the base plate 28 of the filter holder 27 and are integral with the paper holding ribs 29. The guide rib 29b has an inclined outer surface and reinforces the junction between the paper holding rib 29 and the base plate 28. When the filter holder 27 is fitted into the dust case 19, the guide ribs 29 guide the holder 27 by the contact of their outer surfaces with the packing frame 24 of the dust case 19, whereby the holder 27 can be placed in position within the dust case 19. The base plate 28 extends forward beyond the first and second openings 8a and 20a to provide at its forward end a tubular , . . .
o opening member having a suction opening 30 for admittlng dust or dirt into the dust case 19. The outlet end of the suctlon opening member opposite to the opening 30 is covered with a flapper valve 30a of synthetic rubber.
The suction opening member has a constricted portion 30b fitting in the first and second openlngs 3a, 20a.
Commercial tissue paper or kitchen paper is utilized as it is as a paper filter 31. The paper filter 31 can be placed into the dust case 19 fitted in the recess 9 and held between the filter holder 27 and the case 19 by placing the central portion of the filter 31 over the upward opening 20 of the dust case 19 and then fitting the filter holder 27 into the dust case 19. When thus set in place, the paper filter 31 has its central portion extended over the interior surface of the dust case 19 by the paper holding ribs 29 of the holder 27, providing a wide dust collecting space. The margin 31a of the paper filter 31 is folded over the surface of the base plate 28 of the filter holder 27, and the closure 13 is closed, whereby the margin 31a of the filter i5 held between the holder 27 and the closure 13 and hidden from view.
When the power supply switch 3a is turned on with the handle 5 grasped by hand, the rechargeable power supply batteries 4 drive the fan motor 2. Accordingly, dirt 1S drawn into the dust case 19 through the suction opening 30 and collected by the paper filter 31. At this time, the paper filter 31 is held in intimate contact with the lnner side of the dust case 19, retained in shape by the case 19 and thereby protected from breaking. secause there is a space in the dust collecting recess 9 aroun~
the dust case 19, i.e., between the outer peripheral surface of the mesh filter portion 21 of the case 19 and the inner surface of the main body 1 defining Ihe recess 9, and further because the air drawn in flows also through the cutouts 29a in the paper holding ribs 29 and then through the side portions of the case 19, a wide filtering area is available. Since the dirt drawn in passes through the alr passing cutouts 29a and accumulates also on opposite side portions of the paper filter 31, dirt can be trapped efficiently by the paper filter 31 over the entire surface thereof. Accordingly, the cleaner gets a larger dirt-collecting capacity, so that this reduces the number of times dirt is to be discarded.
For the discard of the dirt, the closure 13 is turned open, the margin 31a of the paper filter 31 is unfolded, the filter holder 27 is removed, the paper filter 31 is further removed with the dirt accumulated thereon by holding the marging 31à with hand, and the paper filter and dirt are discarded.
The dust case 19 can be fitted into the recess 9 i'7S ~0 acculately in position, with the lugs 26 positioned outside the upper opening edge 22 of the recessed portion 9, merely by placing the dust case 19 into the recess 9.
Further the packing frame 24 enables the closure 13 to close the dust case 19 effectively. Because of these features, the present cleaner achieves a high dirt collect-ing efficiency. For the disposal of dirt, the dust case 19 is readily removable from the dust collecting recess 9 by pulling out the lugs 26 with fingers.
The present vacuum cleaner is operable for cleaning even when no paper filter is used. In this case, the dirt drawn in tnrough the suction opening 30 can be trapped by the mesh filter portion 21 of the dust case 19 serving as a filter wall. When a large amount of dirt has been collected in the dust case 19, the case 19 is removed from the main body 1, carried to a suitable place of dirt disposal and emptied of the dirt as in the case where the paper filter 31 is used. Since the upward opening 20 of the dust case 19 is held closed with the filter holder 27, the dust case 19 can be removed and carried without spilling the dirt. The dirt is therefore disposable with great ease.
` Also when the paper filter 31 is used, dirt can of course be discarded along with the filter by removing the dust case 19 from the main body 1 first with the filter ~ti7S~0 holder 27 attached to the case and thereafter removing the filter holder 27 therefrom at the place of dirt disposal.
Thus, the dirt is readily disposable without spillins.
Figs. 5 (A) and 5 (B) show another embodiment of the invention. Each of the parts corresponding to those of the first embodiment is designated by the same corre-sponding reference number plus 100.

For the discard of the dirt, the closure 13 is turned open, the margin 31a of the paper filter 31 is unfolded, the filter holder 27 is removed, the paper filter 31 is further removed with the dirt accumulated thereon by holding the marging 31à with hand, and the paper filter and dirt are discarded.
The dust case 19 can be fitted into the recess 9 i'7S ~0 acculately in position, with the lugs 26 positioned outside the upper opening edge 22 of the recessed portion 9, merely by placing the dust case 19 into the recess 9.
Further the packing frame 24 enables the closure 13 to close the dust case 19 effectively. Because of these features, the present cleaner achieves a high dirt collect-ing efficiency. For the disposal of dirt, the dust case 19 is readily removable from the dust collecting recess 9 by pulling out the lugs 26 with fingers.
The present vacuum cleaner is operable for cleaning even when no paper filter is used. In this case, the dirt drawn in tnrough the suction opening 30 can be trapped by the mesh filter portion 21 of the dust case 19 serving as a filter wall. When a large amount of dirt has been collected in the dust case 19, the case 19 is removed from the main body 1, carried to a suitable place of dirt disposal and emptied of the dirt as in the case where the paper filter 31 is used. Since the upward opening 20 of the dust case 19 is held closed with the filter holder 27, the dust case 19 can be removed and carried without spilling the dirt. The dirt is therefore disposable with great ease.
` Also when the paper filter 31 is used, dirt can of course be discarded along with the filter by removing the dust case 19 from the main body 1 first with the filter ~ti7S~0 holder 27 attached to the case and thereafter removing the filter holder 27 therefrom at the place of dirt disposal.
Thus, the dirt is readily disposable without spillins.
Figs. 5 (A) and 5 (B) show another embodiment of the invention. Each of the parts corresponding to those of the first embodiment is designated by the same corre-sponding reference number plus 100.
