The specific embodiment

Dust absorption nozzle for floor 1 from Fig. 1 to electric dust collector shown in Figure 30 is made of cleaner head main body case 2, rotating brush 3, union elbow 4, cover 5, wherein, constitute by top box 2a and nowel 2b at laterally long cleaner head main body case 2, be formed with on it from following to the very big suction inlet 6 of front openings; Rotating brush 3 can be supported on the two ends of the length direction in the cleaner head main body case 2 with rotating freely by bearing portion; Union elbow 4 can be installed in back one side of cleaner head main body case 2 up and down freely to rotate, and is communicated with above-mentioned suction inlet 6; Cover 5 constitutes the antetheca of cleaner head main body case 2, can open and close the front part 6b of suction inlet 6 simultaneously, and union elbow 4 is connected with main body of dust collector by not shown prolongation pipe or flexible pipe.In addition, be formed on the hairbrush 90 that is equipped with horizontal length in the groove at rear, bottom surface of above-mentioned nowel 2b, can contact with cleaning face and clean.In addition, said brush 90 have can dismounting on above-mentioned case 2b structure, therefore when brush is made dirty, can take off from nowel 2b and clean.

As Fig. 5 and shown in Figure 6, on above-mentioned rotating brush 3, with the angle of five equilibrium, for example the interval of 90o or 60o is formed with a plurality of spiral helicine brush bodies (or scraping lamellar body) 8 along length direction on the outer peripheral face of its core body 7.The concrete method to set up of brush body 8 can be to install by its root 8b is embedded in the spiral helicine groove that forms on the outer peripheral face of core body 7.In addition, though show among the figure, brush body 8 is by conveyer belt etc. its driving force to be passed to brush body and rotate by being built in brush motor 101 in the cleaner head main body case 2.By the rotation of this brush body 8, the dust of floor surface is scraped down, and then is inhaled into mouthful 6 suctions effectively, thereby makes floor surface by cleaning is clean expeditiously.

Near above-mentioned brush body 8 and coat the above-mentioned cover 5 of the place ahead part, though show among the figure, be formed with arm in the both end sides of the length direction of cover 5, cover 5 and can be supported on the inboard at the both ends of main body case freely to rotate by this arm.In addition, the both ends of roller 9 can be installed by the 9a of bearing portion, 9b on above-mentioned cover 5 with rotating freely, during on cleaning wall limit etc., the front end of cleaner head contacts with metope, roller 9 rotates, make cover 5 rotate upward, and the place ahead of suction inlet 6 is partially opened, here, the position of cover 5 turning cylinder and roller 9 relation is as follows, roller 9 be set at liken to for the turning cylinder that covers 5 center of rotation more by last position, make the roller 9 be positioned at the cover forefront on being pressed against metope the time, roller 9 is rotated counterclockwise, and covers 5 simultaneously and rotates upward, so just can open so that cover 5.

Though show among the figure in addition, be equipped with on the turning cylinder of above-mentioned cover 5 as to covering 5 torsionsprings (not shown) that apply the force application apparatus of the power that rotates direction.Therefore, do not contact and when carrying out common floor surface cleaning, cover 5 is partially enclosed with the place ahead of suction inlet 6, has only the below part to open wide at the front end of cleaner head with metope such as wall limit.In addition as shown in Figure 9, partly be provided with in order to cover 5 from rear end part at top box 2a and pack into and the housing recess 10 of the empty shape that forms,, cover 5 is accommodated in the inboard of cleaner head main body case 2 with when cover 5 is opened.

And, above-mentioned roller 9 is when dust catcher cleans, the cushioning effect of the impact in the time of can also bringing into play front one side that absorbs cleaner head main body case 2 and contact with barrier, therefore as shown in figure 10, as soft, smooth contact member, the most handy cellulosic member of outer peripheral face nylon loop 11d with cylindrical portion 11A of turning cylinder 11 coats and forms, and so just can prevent the damage to metope or furniture reliably, and cover 5 is very successfully rotated.When under roller 9 and metope state of contact, carrying out horizontal cleaning in addition, also help move left and right successfully by nylon loop 11d.

Here, the rotating brush 3 of above-mentioned cleaner head 1 for can adopt with the identical cleaning mode of wipings such as rag, as shown in Figure 7, has the structure that the installation of can automatically reeling can be adsorbed the absorption thin slice 12 (being designated hereinafter simply as thin slice) of cloth or rubbish such as paper, for example paper for kitchen.

Below, the concrete structure that is used to install this thin slice 12 is further described to Figure 30 with reference to Figure 11.At first, the order that thin slice is installed is, shown in Fig. 7, Figure 14 etc., places rectangular thin slice 12 in the front of cleaner head 1, similarly rotating brush 3 is placed on this thin slice 12 the end above.Make rotating brush 3 rotations if press the running switch of dust catcher under this state, the brush 3 that thin slice 12 just is rotated automatically is wound on the rotating brush 3.And when this thin slice was installed, the rotating speed of rotating brush 3 can be controlled as the suitable degree that can not stave thin slice.

Here, as shown in figure 22, what rotating brush 14 in the past adopted is the general structure that the brush body 13b that is equal length only is set with certain interval (being 90o here) in the periphery of core body 7, the part of brush body 13b being arranged and do not have has ladder difference D between the part of brush body 13b, therefore is difficult to make thin slice 12 to reel equably.

In addition, even also can because the coiling of thin slice 12 makes brush body 13b begin lodging from root 13d, after removing thin slice 12, still keep its deformation state as shown in figure 23 after reeling upward, thereby produce brush body 13b gets deleterious to scraping of dust bad phenomenon.

And for situation of the present invention, rotating brush 3A is Figure 24～structure shown in Figure 26,2 soft hairbrush 15a are equipped on the outside by growing, with 2 short and hard hairbrush 15b be equipped on the 1st inboard brush body 15, implanted the 2nd brush body 16 of the longest hairbrush 16a, the 3rd brush body 17 these three kinds of brush bodies of having implanted the second long hairbrush 17a constitute, its the 1st brush body 15 by with the interval of 120o along 3 row direction of principal axis in the shape of a spiral shape be configured on the outer peripheral face of core body 7, the 2nd brush body 16 and 17 of the 3rd brush bodies are equipped on therebetween, and in the middle of above-mentioned the 1st brush body 15 is clipped in.

Figure 26 is the figure of expression by the state of this rotating brush 3A coiling thin slice 12, and the head end of thin slice 12 (front end) contacts with rotating brush 3A, is accompanied by the rotation of rotating brush 3A, and thin slice 12 just is drawn into, and is wrapped in the periphery of brush body 15～17 simultaneously.When thin slice 12 twines, three kinds of brush bodies 15～17 as shown in figure 25, the hardness (softness) of corresponding hair separately produces distortion (bend mode), its bristle head contact with thin slice 12 inner faces naturally, makes thin slice 12 not be crushed and can keep circle.Like this, thin slice 12 is reeled to stretch conglobate state.In addition, in the 1st brush body 15, the hairbrush 15a of the length in the outside state of being kept upright, its bristle head meets at right angles with the inner surface of thin slice 12 and docks.Because so the intervals with 120 degree have set 3 the 1st brush bodies 15, so 3 brush bodies 15 inboard of support slice 12 like this integrally on 3 of equalization helps making thin slice 12 to keep tension force and coiling uniformly.In addition, therefore the brush body 15b of the weak point on the 1st brush body 15 just can not produce the bad phenomenon that the root as brush body 13b in the past bends owing to can not twined by thin slice 12.

In addition, the the 2nd, the 3rd brush body 16 when the front, during 17 bendings, owing in adjacent above-mentioned the 1st kind to the 3rd kind, there is not very big interval (filling at interval) between any two brush bodies, therefore each brush body 15～17 is moderately crooked after will disperseing from the stress of thin slice 12 to bear, and can be as the root of in the past brush body 13b not crooked to heavens and produce extremely distortion, bending extremely can not take place yet and lose the effect of polishing in brush body 15～17.Can reach three kinds of brush bodies 15～17 of 7 by configuration total equably in addition around core body 7, becoming does not have the rotating brush of ladder difference 3A between brush body and the brush body, and can keep the coiling of the tension force of thin slice 12 yet yet.

Rotating brush 3B shown in Figure 27 also is the another kind of example that can realize winding of webs.In the case, the core body 7 of rotating brush 3B is provided with lug, nib 18,18.Lug, nib 18,18 is for outwards being two fork things that Eight characters shape is opened, be located between brush body 19 and the brush body 19 the outstanding outer peripheral portion that is formed on core body 7 of one.And lug, nib 18,18 and core body 7 form concentric circles, and its length is set to shorter than brush body 19.Like this, utilize lug, nib 18,18 to fill the rotating brush 3B in the space 20 between the brush body 19 like this, because lug, nib 18,18 can be eliminated the ladder that the obstruction thin slice 12 that is produced by part that brush body is arranged and the part that do not have of picture rotating brush 14 is in the past reeled, so can realize the uniform coiling of thin slice 12.

Also thin slice 12 can be wound on the rotating brush 3 with method shown in Figure 8.

That is, thin slice 12 is inserted from case 2 front surfaces of cleaner head 1 and the space be located between the roller 9 on this case 2, utilize just can the reel thin slice 12 of insertion of the brush 3 of rotation.In the case, thin slice 12 utilizes the roller 9 of the width horizontal length wideer than this thin slice 12, push the front edge integral body of thin slice 12 equably, and about also guided by roller 9, send into the state of uniform spreading owing to the rotation that utilizes roller 9 makes thin slice 12 integral body like this, therefore it can be wound on the rotating brush 3 equably.So, explanation inserts thin slice 12 under the situation of the rotating brush 3 in the suction inlet 6 from the front lower place of cleaner head 1 in front, position deviation when thin slice 12 of Chan Shenging and rotating brush 3 are located often, make thin slice 12 form the inclined to one side state of inserting, will produce the problem that can not obtain desirable wiping effect like this, it is wrinkling and cause the breakage of thin slice 12 when perhaps the front edge of thin slice 12 begins to reel, the problem of inhomogeneous installation, also have the sagging back of coiling clearing end of thin slice 12 to contact problems such as producing noise with floor surface in addition, and the guide function that utilizes roller 9 can be eliminated above problem, is favourable in this therefore.

Under the situation that the above-mentioned guiding that utilizes roller 9 to carry out thin slice 12 is carried, as shown in Figure 8, nylon loop 23 is installed on roller 9.This is because roller 9 is the less rollers of resistance such as resin, skids easily when roller 9 guiding thin slices 12, thereby is difficult to be reeled uniformly effect, therefore installs, implants nylon loop 23 on the outer peripheral face of roller 9.After the outer peripheral portion of this roller 9 is provided with the member that nylon loop 23 grades have big resistance, just can strengthen the contact resistance between roller 9 and the thin slice 12, thereby thin slice integral body is spread out equably, more reliably and successfully send into, can also fifty-fifty thin slice 12 be wound in addition on the rotating brush 3 in the air entry 6.

Shown in Fig. 7, Figure 14 etc., after on the rotating brush 3 that thin slice 12 is wound on said structure,, just can use thin slice 12 dirt or the dust of wiping floor surface reliably like this by making it rotation.Can also increase polishing effect in addition, sweep floor surface cleaner.

On the other hand, when after finishing wiping, black thin slice 12 being abandoned, and change when new thin slice 12 is installed, be necessary thin slice 12 is taken off.Just thin slice 12 can be taken off with hand.As shown in Figure 9, the coiling that pinches the thin slice 12 on the rotating brush 3 that is wound in the suction inlet 6 with hand stops the free end 12d of side, stretches to oneself layback, just can take off with hand.Perhaps as shown in figure 13,, make the fore-end of thin slice contact and be stripped from, thereby make thin slice 12 uncoiling and being removed from the rotating brush 3 naturally with the front end 5d that covers 5 by rotating rotating brush 3.Need make rotating brush reverse this moment as described later.

When taking off thin slice 12, as noted above in addition, when shutter 5 forms the antetheca of cleaner head main body case 2 up and down, thin slice 12 just easier taking-ups.Cover 5 is by spring etc. when closed, as shown in Figure 9, to cover 5 by manual operation and pack into after main body case inside is moved upward and opens as shutter as receipts, suction inlet 6 just only becomes the big opening of also forwards opening towards the little opening below, that be difficult to take out before the cover opening operation.Therefore, hand just can touch thin slice 12 from the opening 6b of front part, thereby can easily pinch thin slice 12 and with its taking-up.

In addition, under situation about thin slice 12 being wound on the rotating brush 3, will be very convenient in the time can confirming reeling condition simply.Just as shown in figure 11, make the front surface portion of cleaner head main body case 2 form hyalomere 12A, perhaps as shown in figure 12, peep hole 24 is set, the peep hole 24,24 of pair of right and left is set this moment in the part of the front face of cleaner head main body case 2 with transparent component.In addition, peep hole 24 can adopt the transparency window of the transparent component covering that can not be invaded by dust.Like this, just can know reliably whether thin slice 12 reels on, under the coiling condition of poor, normally install after can also reeling again.

In addition, as thin slice, can use that as shown in figure 15 the rear end with thin slice 12 is oblique is cut into leg-of-mutton material, also can use the rear end with thin slice 12 shown in Figure 16 to be cut into the material of M word shape, so just can reduce owing to the end swing of thin slice 12, beat the abnormal sound of floor.

That is to say that when turning round, because the rear part of thin slice (end of reeling and stopping) swing, perhaps the thin slice end is sucked into situations such as suction inlet, can produce abnormal sound after adopting general rectangular winding of webs.In contrast, after as above-mentioned thin slice 12, the end being made triangle or M word shape, because thin slice end 12b, 12c, 12c diminish with the area that floor or case (cleaner head main body case) contact, can as rectangle thin slice in the past, not produce the phenomenon that floor is beaten in the end, therefore just can suppress the generation of abnormal sound.Can also suppress the swing (Dutch roll) of thin slice end in addition.

The coiling end that Figure 17～Figure 19 represents to make thin slice 12 can be by other thin slice of volume wrinkle.

Thin slice 12 among Figure 17 is gone up by making or the bonding cord 25 that is provided with at the fore-end (coiling starting end) of thin slice 12.At this moment, as shown in figure 18,, just can begin to reel securely from fore-end by cord 25 being wrapped on the brush body arbitrarily 8 of rotating brush 3.

Thin slice 12 among Figure 19 is sewed on wire 26 hard materials such as grade at head end, makes front end (coiling starting end) become hard structure, promptly becomes the end edge portion 27 of hardization.By adopting this formation, when thin slice is installed, the thin slice front ends is entirely launched by metal 26 thus, front ends just can crumple, thereby is installed on the rotating brush 3 with uniform state, carries out stable coiling.

And, under the situation of Figure 20, be provided with the circle of cord 28 on the both sides of the fore-end of thin slice 12.On the other hand, at rotating brush 12 1 square one-tenth the circle of cord 28 is hooked on hook 29 on the core body 7.By adopting this formation, can be hooked on the hook 29 by circle as shown in figure 21 cord 28, just can begin to reel equably successively from front ends.In addition, the belt that utilization can be taken off also can be fixed on the end of thin slice 12 on the core body of rotating brush 3.

In the end of thin slice 12 fixed structure is set like this, the front edge that just can make thin slice 12 can crumple, thereby can be wound on the rotating brush 3 with even and stable status.

Though change the shape of thin slice 12 like this, or setting is installed in the mechanism on the rotating brush 3, make thin slice 12 easier installations, but also can produce as the brush body (scraping blade) 8 of rotating brush 3 to as Fig. 5, as shown in Figure 20 situation towards the shape of a direction spiral, and remain in operation along with the coiling of thin slice 12 or after reeling, thin slice 12 is oblique to a lateral deviation, thereby reduces the situation of wiping effect and floor polishing effect.

Consider this point, after on the side face that brush body (scraping blade) 8 is arranged on core body 7, preferably as shown in figure 28, when level is observed core body 7, make brush body (scraping blade) 8 be the form configuration of V word shape.That is, preferably brush body (scraping blade) 8 is formed length direction middle body one direction towards axle and be wound on shape on the core body 7 obliquely, and be configured to turn back to the shape that is wound on obliquely in the other direction on the core body 7 from middle body.

Like this, the thin slice 12 on reeling in the surface back of contact brush body 8, though the rotation by rotating brush 3, the contact resistance of the brush body 8 of the configuration that is subjected to being in the shape of the letter V as the component of its resistance, acts on about the power edge with thin slice 12 mutual draw directions.So just can prevent that thin slice 12 from moving and the problem that deflects away to a side.Like this, can also in rotation, make thin slice 12 keep being wound on the normal position, thereby can obtain very desirable wiping and polishing effect.

Figure 29 is illustrated in the structure that main body case 2 one side being provided with have the guiding lug, nib 30 of same thin slice stretching action, is formed with the guiding lug, nib 30 around ground, the position, top of brush along the shape of its rotational trajectory on the inside wall 2D of main body case 2 (top box 2a).In addition, this guiding lug, nib 30 is configured to the V font that stretches to two side directions from the length direction middle body of the axle of rotating brush 3.In addition, the outstanding length of front end of guiding lug, nib 30 is set to the degree that just in time can touch the thin slice 12 that is wound on the rotating brush 3.Guiding thin slice 12 by the guiding lug, nib 30 that is provided with in this manner, and the contact resistance of utilization generation when contacting with thin slice 12, just can produce the component of thin slice 12 to the draw direction effect.Consequently, the thin slice 12 of rotation can keep correct position when reeling naturally, also can keep smooth extended state behind coiling, can on core body 7 lateral run-out not take place simultaneously, thereby keeps being wound on the correct position.Therefore, same wiping and polishing effect in the time of can obtaining with the front with V font configuration brush body 8.

Below, with reference to Figure 31～Figure 34 the control of rotating brush 3 of the present invention is described.

Electric dust collector as shown in figure 31, by constituting with the lower part, that is: the main body of dust collector 34 of the electric blower 33 (with reference to Figure 33) used of built-in control of dust, be connected flexible hose 35A on this main body of dust collector 34, be connected prolongation pipe 35B on this flexible hose, be provided in switch portion on hand 38 shown in Figure 32 on the handle portion 37 on the connection side of the above-mentioned prolongation pipe that is formed at above-mentioned flexible hose 36, built-in rotating brush 3 and this rotating brush 3 is rotated the CD-ROM drive motor 40 (with reference to Figure 33) of driving and is connected dust absorption nozzle for floor 1 on the above-mentioned prolongation pipe 35B.

On above-mentioned switch portion on hand 38, shown in figure 32, be provided with the console switch that is used to carry out various runnings, what for example strengthen the strong switch 41 of inlet capacity, the weak switch 42 that weakens inlet capacity, the shutdown switch 43 that stops dust catcher running, floor polishing mode switch 44, paper peels off switch 45.

If push above-mentioned strong switch 41, then electric blower 33 will rotate at a high speed, the inlet capacity height of dust catcher.In addition, if push above-mentioned weak switch 42, then electric blower 33 will low speed rotation, a little less than the inlet capacity of dust catcher.

Shutdown switch 43 1 is pressed will make electric blower 33 stop, and the CD-ROM drive motor 40 that rotating brush 3 is rotated driving is stopped, thereby fully stops the running of dust catcher.

In addition, above-mentioned floor polishing switch 44 as described later shown in, it is the switch that uses when carrying out wiping after the thin slice 12 that can adsorb rubbish such as paper for kitchen is installed on the above-mentioned rotating brush 3, rotating speed (low speed) in when operation with the installation of the most suitable thin slice 12 drives CD-ROM drive motor 38, makes above-mentioned rotating brush 3 rotate.Like this, be accompanied by its rotation, thin slice 12 just automatically is wound on the rotating brush 3.

In addition, after thin slice is installed, when carrying out the operation of above-mentioned floor polishing mode switch 44, also need be rotated control to rotating brush 3 with the rotating speed (low speed) of the best that can carry out floor polishing (erasing) well.So just erasing falls on the ground the dirt on plate surface neatly, and in addition, the spin balancing that destroys owing to the installation of thin slice is easy to generate abnormal sound more under high more speed, utilize above method can avoid such situation, thereby can undisturbedly turn round.

In addition, the above-mentioned switch 45 of peeling off is the switches that use when rotating brush 3 takes off with above-mentioned thin slice 12, in use CD-ROM drive motor 40 is reversed driving with the rotating speed (low speed) that the best is automatically peeled off thin slice 12, thereby make rotating brush 3 that counter-rotating take place.

And, be provided with the floor detecting switch 46 (with reference to Figure 33) that brush motor 20 is carried out the open and close operation in the bottom of dust absorption nozzle for floor 1, it is used to detect cleaner head 1 is to be in the state that contacts with floor surface 24 and clean, still be in leave floor surface 24 do not carry out the cleaning state.In the case, floor detecting switch 46 is to utilize the structure that is applied the wheel that can move up and down 47 of downward power by elastic components such as springs usually and carry out work, at the wheel 47 of cleaner head 1 with after floor surface 24 contacts, when the resistance spring is moved upward, the operation that execution is opened is rotated driving to the CD-ROM drive motor 40 of rotating brush 3.When wheel 47 is subjected to the effect of the spring force that leaves from floor surface 24 and when outstanding, carries out the operation of closing downwards, CD-ROM drive motor 40 is stopped.Like this, rotating brush 3 rotates when cleaning with cleaner head 1 contact floor surface 24, cleaner head 1 is not left when not cleaning behind the floor surface 24 and is then stopped the rotation, and utilizes the dust absorption nozzle for floor 1 and the contact separation state of floor surface 24 automatically to be rotated the running of brush 3/stop control like this.

These dust absorption nozzle for floor with said structure are by the control of turning round of as shown in figure 33 control loop.Input is from the operation signal of above-mentioned each switch 41～46 in microcomputer 48, and according to these signals, microcomputer 48 is by brush motor drive circuit 49 and suck motor drive circuit 50 respectively to the control of turning round of CD-ROM drive motor 40 or electric blower 33.

Figure 34 represents the control flow that utilizes above-mentioned control circuit to control.To utilize this control flow that the method for control is further described below.

Implement the control of the state of corresponding each switch by the startup of flow process.In order to carry out under the situation of the wiping that thin slice 12 is installed on the rotating brush 3, press floor polishing mode switch 44 (handling 51) to the floor surface cleaning.Floor polishing mode switch 44 1 is pressed, and the rotating speed rotation control CD-ROM drive motor 40 (handling 52) of thin slice 12 just is installed with the best by above-mentioned microcomputer 48 and brush motor drive circuit 49.Therefore, thin slice 12 just can automatically be installed on the rotating brush 3 of rotation by coiling.What carry out this control is the 1st control device.

In addition, electric blower utilization suction this moment motor drive circuit 50 is rotated (handling 53) with the speed of the best.Wish attraction weakens does not have influence for the installation to thin slice situation.What carry out this control is the 2nd control device.

So just can utilize 1 pair of floor surface 24 of cleaner head that thin slice 12 has been installed on rotating brush 3 to clean.At this moment, judge the ON/OFF state (judging 54) of floor detecting switch 46, when cleaner head contacts with floor surface 24, (judges 54y) when the floor detecting switch is ON, continue to implement to handle 52,53, thin slice 12 can continue to carry out wiping with the rotation status of best (low speed).

On the other hand, when cleaner head 1 floor surface 24 away from keyboard, and when being in the state that always leaves, floor detecting switch 46 becomes OFF (judging 54n), thereby makes CD-ROM drive motor 40 stop (handling 55).Therefore, as long as leave floor surface 24 just stalls immediately, the running noise in the time of therefore can reducing wiping because the rotating brush 3 of thin slice 12 has been installed.

Then, when taking off black thin slice 12, press and peel off switch 45.This switch 41 1 is pressed (handling 61), and CD-ROM drive motor 40 just is subjected to the rotation control of above-mentioned microcomputer 48 and brush motor drive circuit 49, and its rotating speed is controlled as the best degree (low speed) that thin slice is taken off (handling 62).When rotating brush 3 carried out counter-rotating with low speed, as shown in figure 13, the free end 12d of the coiling dwell section of thin slice 12 contacted with the front end 5d of cover 5.After contact, owing to being further rotated of rotating brush 3, the front end 5d of this cover 5 peels off thin slice 12 at leisure, and thin slice 12 just automatically takes off after fully peeling off soon.What carry out this control is the 3rd control device.

Switch 38,39 etc. is to make rotating brush 3 rotations in that thin slice 12 is not installed, use (handling 71,72) when carrying out common cleaning when getting dust scraping, after being pressed respectively, suck motor and carry out high speed rotation (locating 73) and low speed rotation (processing 74) respectively, attraction is grow or die down also.According to the ON/OFF operation of floor detecting switch 46, CD-ROM drive motor 40 is driven control in addition.At this moment, when floor detecting switch 46 becomes ON, promptly cleaner head 1 is placed on when cleaning on the floor surface, carries out high speed rotation control (handling 76) with 49 pairs of CD-ROM drive motors of brush motor drive circuit 40.Do not dally, while and scrape and get rubbish and turn round.

Shutdown switch 43 1 is pressed (handling 81), and electric blower 33 and CD-ROM drive motor 40 are stopped (locating 82,83), thereby whole runnings of dust catcher all stop.

And, after above-mentioned floor polishing mode switch 44 is pressed, pressing shutdown switch 43, if the running of dust catcher can not stop for the time being fully, then also will lose efficacy to other the operation of console switch 41,42,45.Like this, because can be under the state that thin slice 12 has been installed, enter common rotating brush 3 and rotate at a high speed and scrape the operation mode of getting dust, therefore, even pressing switch 41,42 unintentionally, because rotating brush 3 can not turn round, therefore can not make the situation of thin slice 12 breakages of being installed.

As implied above, dust absorption nozzle for floor 1 when carrying out the cleaning of straw mat or carpet etc., need not be installed thin slice 12 and utilize cleaning of dust catcher, scrapes to get dust and suck dust by suction inlet with rotating brush 3 and cleans.And when carrying out the cleaning of floor surfaces such as floor, thin slice 12 is wound on the rotating brush 3, utilize the thin slice 12 that together rotates with brush, in the wiping floor surface, can also play the effect of floor polishing, therefore can clean effectively.

(invention effect)

As implied above, according to the present invention, when installation can be adsorbed the thin slice of dust on the rotating brush that adopts in cleaner head, owing to utilize the operation of floor polishing mode switch, rotating brush can be controlled to be and be suitable for the convenient rotating speed that thin slice is installed, therefore thin slice just can automatically be installed, and can be not damaged.In addition, even owing to also be controlled to be appropriate rotating speed after thin slice is installed, it is little therefore can to obtain operating sound, and can carry out dirt or the erasing of dust and the dust catcher of floor polishing of floor surface well.

In addition, meanwhile, because electric blower also is controlled as the suitable state that thin slice can not drawn in consumingly, so the installation of thin slice becomes easier.

In addition, when carrying out floor polishing, utilization is arranged on the floor detecting switch of the bottom of cleaner head, can be according to the state that contacts or leave with floor surface, the operation that rotating brush is turned round/stops, even therefore cleaner head is the short time to leave floor surface, running also can stop, thereby the noise that produces in the cleaning is tailed off.

In addition, also be provided with the switch of peeling off that when utilizing rotating brush to remove thin slice, uses,, can make rotating brush to be suitable for untiing the low speed counter-rotating of thin slice by using this switch, thereby can automatically take off, so the operations such as replacing of thin slice just become simple and convenient.
