Abstract
An electric vacuum cleaner includes a cleaner body, dust collector, and handle. The handle has an engaging section at an end, and the dust collector has a first target section for the engaging section. An engagement of the engaging section with the first target section allows the handle to be kept standing. The cleaner body has a second target section for the engaging section, and an engagement of the engaging section with the second target section allows the cleaner body to hold the dust collector. When the dust collector is mounted to the cleaner body with the handle standing, the engagement of the engaging section with the first target section is released, and the engaging section engages with the second target section.
Description
- The present invention relates to an electric vacuum cleaner.
- A conventional cyclone-type electric vacuum cleaner includes a dust collector, which has a handle rotatably supported on a shaft and disposed at an upper section of the dust collector. A claw is fixedly provided to an end of the handle. When a user mounts the dust collector to a cleaner body, the dust collector is held upright before it is mounted to the cleaner body. Then the user aligns the claw of the handle with an engaging section of the cleaner body, and rotates the handle from a standing state to a rest state while the claw fits into the engaging section. The dust collector is thus rigidly mounted to the cleaner body (e.g. refer to
Patent Literature 1.) - However, the foregoing conventional cleaner needs improvement for better usability. To be more specific, the dust collector cannot be mounted to the cleaner body with the handle being kept standing, so that the user should rotate the handle from the standing state to the rest state with the claw being aligned with the engaging section of the cleaner body. It thus requires a cumbersome time for mounting the dust collector to the cleaner body, and this mechanism degrades the usability of the vacuum cleaner.

First stage filter 19 is made of metallic material, and the metallic surface offirst stage filter 19 should be free from peaks and valleys formed of resin so that a circling air-stream can travel smoothly. The foregoing structure allows the dust to be separated more efficiently, and thus prevents the dust from twining. A polished surface offirst stage filter 19 will also allows the dust to be separated efficiently.First stage filter 19 having undergone the antibacterial process can be kept clean. -
Upper lid 16 is disposed abovecollector body 15 such that it coversdust removing section 24 andmotor 25 therein and caps the top face ofcollector body 15. AsFig. 4 shows, handle 18 is rotatably supported on a shaft ofupper lid 16.Handle 18 includesfirst claw 26 at its end to be used for engagement. Ontop face 16b ofupper lid 16,first recess 27 working as a first target section for the engaging section is formed, andfirst recess 27 is engaged withfirst claw 26 so that handle 18 can be kept in a standing position when handle 18 stands at 90° or more relative totop face 16b ofupper lid 16. As shown inFig. 3 ,second claw 29 is formed at the front ofupper lid 16, andsecond claw 29 engages withthird recess 28 provided to handle 18 so that handle 18 can be laid in a rest state. - As
Fig. 4 shows,operational section 30 is provided to a rear upper section ofupper lid 16, and it is used for openinglower lid 17.Upper lid 16 also includesdischarge port 16a at the rear section for communicating with blower 9 whendust collector 2 is mounted tocleaner body 1. The air from which the dust is separated indust collector 2 is discharged outsidedust collector 2 through thisdischarge port 16a. - As
Fig. 3 shows, hinged lower-lid 17 is provided pivotably to hingesection 31 ofcollector body 15, and it is attached tocollector body 15 bybuckle 32 provided tocollector body 15 withopening 15a closed.Lower lid 17 includes packing 33 at a position confrontingcollector body 15, and packing 33 allowslower lid 17 to covercollector body 15 air-tightly. - A user operates
operational section 30 to push downslider 34 provided to the rear section ofcollector body 15, andslider 34 rotatesbuckle 32 for releasing the engagement betweenlower lid 17 andbuckle 32, so that opening 15a is opened.Recess 17a is formed at approx. center oflower lid 17 for mating withprotrusion 11a (shown inFig. 2 ) formed ondust collector receptor 11. - The operation of
electric vacuum cleaner 100 with the structure discussed above is demonstrated hereinafter. When a user holdsgrip 6 shown inFig. 1 and starts working cleaner 100, blower 9 generates suction wind, so that suction force is produced. A movement of suckingdevice 3 on a target face allows suckingdevice 3 to suck the dust on the target face together with air, then the air containing the dust flows intocleaner body 1 viaextension pipe 4,hose 5, andsuction port 1a. The air containing the dust then flows intodust collector 2 throughintake port 15b shown inFig. 4 . - The air containing the dust then flows into
cyclone space 35 formed of the outer periphery offirst stage filter 19 shown inFig. 3 andcollector body 15, and then the air is separated by centrifugal force, caused by the circling air-stream generated incyclone space 35, into rough dust chiefly formed of dust balls and air still containing fine dust. The rough dust chiefly formed of dust balls passes throughdust collecting path 36 formed betweenextension part 21 andcollector body 15, and is accumulated indust accumulation space 37. - The rough dust is centrifuged in
cyclone space 35, and the remaining air still containing fine dust passes throughfirst stage filter 19, and then the fine dust is filtered bysecond stage filter 23. As a result, the air without the fine dust passes throughsecond stage filter 23 and is discharged outsidedust collector 2 fromdischarge port 16a (shown inFig. 4 ). The discharged air is sucked by blower 9 and discharged outsidecleaner body 1 from a discharge port (not shown) provided tocleaner body 1. - During a halt of blower 9, the fine dust accumulated in
second stage filter 23 drops therefrom due to the vibration applied bymotor 25 to dust removingsection 24 disposed abovefilter 23. The fine dust dropped passes through the space inside the mountingframe 20 of the first stage filter, and is accumulated in innercylindrical section 22 disposed underfirst stage filter 19 and yetinside extension part 21. - Next, when the user dumps the dust accumulated in
dust collector 2, the user takes the following actions: Move upward thehandle 18 disposed onupper lid 16 ofdust collector 2, then this action releases the engagement between first claw 26 (shown inFig. 4 ) disposed at the end ofhandle 18 andsecond recess 14a (shown inFig. 2 ) disposed onhandle 14 ofcleaner body 1, so thatdust collector 2 can be detached fromcleaner body 1. Afterdust collector 2 is detached fromcleaner body 1, the user stands handle 18 at an angle ranging from 90° to 140° (inclusive) relative totop face 16b ofupper lid 16. -
First claw 26 andfirst recess 27 both shown inFig 4 are engaged with each other, thereby standinghandle 18 stably. In this state, the user holdshandle 18, and movesdust collector 2 above a garbage box before manipulatingoperational section 30, which pushes downslider 34 for rotatingbuckle 32, whereby the engagement betweenlower lid 17 andbuckle 32 is released. The dust is then discharged from opening 15a to the outside ofdust collector 2. - Next, in the case of mounting
dust collector 2 tocleaner body 1, the user takes the following actions, which are described with reference toFigs. 5A and 5B. Fig. 5A is a lateral view of the cleaner body to which the dust collector is going to be mounted, andFig. 5B is a lateral view of the cleaner body with the dust collector mounted. - When the user dumps the dust accumulated in
dust collector 2 and then restoresdust collector 2 tocleaner body 1, the user takes the following action whilehandle 18 is kept standing: Theuser mates recess 17a (shown inFig. 3 ) provided tolower lid 17 withprotrusion 11a (shown inFig. 2 ) provided todust collector receptor 11 ofcleaner body 1, thereby positioningdust collector 2 tocleaner body 1.Dust collector 2 is thus mounted tocleaner body 1. In other words, as shown inFigs. 2 and3 ,protrusion 11a is provided tocleaner body 1 such that it confrontsbottom face 2a ofdust collector 2, andrecess 17a is provide tobottom face 2a ofdust collector 2 so thatprotrusion 11a can mate withrecess 17a. - As
Figs. 5A and 5B show, when the user mountsdust collector 2 tocleaner body 1 withhandle 18 standing, handle 18 disposed atupper lid 16 ofdust collector 2 is brought into contact withhandle 14 disposed on the upper section ofcleaner body 1. Thenfirst claw 26 is released fromfirst recess 27, so thathandle 18 rotates from the standing state (Fig. 5A ) to a rest state (Fig. 5B ), andfirst claw 26 engages withsecond recess 14a. In this state, the user pushes downhandle 18 so thatsecond claw 29 engages withthird recess 28 shown inFig. 3 , wherebydust collector 2 is mounted tocleaner body 1. - As discussed above and shown in
Figs. 2 and3 , when the user mountsdust collector 2 tocleaner body 1, theuser mates protrusion 11a withrecess 17a for positioningdust collector 2 tocleaner body 1 with ease.Dust collector 2 can be thus mounted tocleaner body 1 with ease, and as a result, the usability ofelectric vacuum cleaner 100 can be further improved. - As shown in
Fig. 5B , whendust collector 2 is mounted tocleaner body 1 withhandle 18 standing, handle 18 is brought into contact withhandle 14, andfirst claw 26 is released fromfirst recess 27, so thathandle 18 rotates from the standing state to the rest state. On top of that, this structure allowsfirst claw 26 to engage withsecond recess 14a, so thatdust collector 2 can be mounted tocleaner body 1 withhandle 18 standing. The user thus needs not to rotate handle 18 from the standing state to the rest state while the user alignsfirst claw 26 withsecond recess 14a.Dust collector 2 can be thus mounted tocleaner body 1 with ease, and the usability ofelectric vacuum cleaner 100 can be thus improved. - As shown in
Fig. 4 ,first claw 26 engages withfirst recess 27 whilehandle 18 stands at an angle ranging from 90° to 140° (inclusive) relative totop face 16b ofupper lid 16, so thathandle 18 is kept in the standing position rigidly.Operational section 30 is provided to the upper rear ofupper lid 16 for the user to manipulate it with one hand, the dust can be thus discharged with ease, and the usability improves. - In the case of
top face 16b ofupper lid 16 being parallel to the floor, it is preferable to keephandle 18 standing at an angle ranging from 90° to 140° (inclusive) relative totop face 16b ofupper lid 16, and it is more preferable to keephandle 18 standing at an angle ranging from 90° to 130° (inclusive). A greater angle included betweenhandle 18 andtop face 16b allows the user to manipulateoperational section 30 with more ease while the user holdshandle 18. However, an excessively greater angle will narrow a clearance betweenhandle 18 andoperational section 30, so that it is difficult for the user to holdhandle 18. - As shown in
Fig. 5B ,dust collector 2 is mounted tocleaner body 1 with angle 38 ranging from 30° to 60° (inclusive). Angle 38 is included betweencenter line 2b of the dust collector andcenter line 1b ofcleaner body 1. This structure allows downsizingcleaner body 1, so thatdust collector 2 can be mounted to cleaner body with ease. - The electric vacuum cleaner of the present invention allows the dust cleaner to be mounted to the cleaner body with ease, so that the vacuum cleaner can improve its usability. The present invention is thus useful for household-use vacuum cleaners and business-use vacuum cleaners.
