Description

Vertical floor-treating device

Technical field

The present invention relates to the floor-treating devices such as a kind of vertical dust catcher, carpet cleaning device or floor cleaning device.

Background technology

Usually, vertical floor-treating device has following structure: have the grip parts such as vertical main part and handle on top, in the bottom of main part, dispose for carrying out the floor treatment section of floor treatment in the mode freely swung with respect to main part.Lower surface rear portion at main part, be typically provided with wheel rotating members such as (or) rollers, in use, the user is operated by gripping handle, can utilize above-mentioned wheel to make floor-treating device desired position carry out floor treatment on the ground.In addition, because being configured to usually with respect to floor treatment section, main part can keep roughly erectility, thereby, when not using, can place with roughly upright state.In addition, when the carrying floor-treating device, by keeping stationary state, handle was fallen as the use state, thereby can utilize wheel that floor-treating device is moved on the ground with the state of floor treatment section floating.

The example as floor-treating device, as shown in figure 14, enumerated the example of vacuum cleaner (suction clearing apparatus), in common vertical type dust collector 610 in the past, handle 614 is positioned at top, main body of dust collector 611 with suction motor, dust collecting part is positioned at bottom, and the suction nozzle with battery unit 613 with rotating brush etc. is located at this main body of dust collector 611.Usually, this suction nozzle with battery unit 613 is configured to and can take the mouth bolster (not shown) of the bottom of being located at main body of dust collector 611 and swung as axle.In use, by the dust of suction nozzle with battery unit 613 suctions, collected rapidly in main body of dust collector 611.

Like this, because being configured to suction nozzle with battery unit 613, vertical type dust collector 610 is directly connected in main body of dust collector 611, therefore, with the pot type dust catcher, compare have advantages of as follows:, the pot type dust catcher is by coupling together and be used with flexible pipe or extension tube etc. between main body of dust collector and suction nozzle with battery unit, but, in vertical type dust collector 610, main body of dust collector 610 and suction nozzle with battery unit 613 form as one in fact.Therefore, compared with the pot type dust catcher, the mobility of vertical type dust collector 610 is good.In addition, because vertical type dust collector 610 usually has rotating brush and can bring into play stronger control of dust power at suction nozzle with battery unit 613 places, therefore, clean etc. such as preferably being applied to carpet.

While stating common vertical type dust collector 610 in the use, the user is as long as the handle 614 that grips top moves suction nozzle with battery unit 613 by the main body of dust collector 611 of bottom.Thus, the user only depends in fact gripping handle 614 just can operate whole vertical type dust collector 610.

Here, in the time will making vertical type dust collector 610 move along fore-and-aft direction, the user is as long as walk about at fore-and-aft direction on one side, and an edge fore-and-aft direction moves the arm that is gripping handle 614 and gets final product, and it operates than being easier to.But, when making vertical type dust collector 610 change direction, its operability has the tendency of reduction.

Particularly, if the fulcrum in the time of making vertical type dust collector 610 change direction is defined as, change direction fulcrum P0, as shown in figure 14, this change direction fulcrum P0 is positioned near the connecting portion of main body of dust collector 611 and suction nozzle with battery unit 613.And, if the length from change direction fulcrum P0 to the front end P1 of suction nozzle with battery unit 613 is defined as to " L1 " and the length from change direction fulcrum P0 to the front end P2 of handle 614 is defined as to " L2 ", length L 2 is longer than length L 1.

In this position relationship, viewpoint definition when suction nozzle with battery unit 613 is changed to direction is angle of travel

The size definition of the displacement by handle 613 now on laterally (direction of intersecting with direct of travel) is displacement WL.So, as shown in figure 14, when user's wish realizes angle of travel

The change direction time, if this user moving handle 614 significantly in the horizontal not can not be realized and angle of travel

Corresponding displacement WL.

Here, control of dust is aspirated to carry out in 613 pairs of ground of suction nozzle with battery unit.Therefore, when using vertical type dust collector 610, at the lower surface of suction nozzle with battery unit 613, can produce the negative pressure for ground is aspirated always.This negative pressure may become resistance when suction nozzle with battery unit 613 is moved.And, if ground is carpet, even the lower surface of suction nozzle with battery unit 613 only merely contacts with carpet pile (carpet pile), also can be subject to corresponding resistance.In addition, if hold together carpet pile while rotating brush rotates, the lower surface of suction nozzle with battery unit 613 can be subject to larger resistance.

In the situation that vertical type dust collector 610 is moved along fore-and-aft direction, the user, as long as move arm along fore-and-aft direction under shoulder, therefore for the user, is easy to arm is exerted oneself.On the other hand, changed in nyctitropic situation, the user also will move arm along fore-and-aft direction when need to move arm along left and right directions.Therefore, with the situation that merely along fore-and-aft direction, moves arm, compare, can need larger power.Its result, can make the operability of vertical type dust collector 610 when changing direction reduce.

Therefore, in the past since, the scheme of the improvement technology of the operability for improving vertical type dust collector has been proposed, for example, in patent documentation 1, the vacuum cleaner improved after handling characteristic is disclosed.This vacuum cleaner comprises: the bottom base; The cylindrical shape motor casing, it is installed on this bottom base, can freely rotate with respect to the bottom base; And free joint, it is installed on this motor casing.Adopt this structure, by reversing the handle of vacuum cleaner, can reverse clockwise or counterclockwise upper body, by the torsion of upper body, direction (clockwise) or left are turned to (counterclockwise) to the right can to make the bottom base.

In addition, in patent documentation 2, the surface processing equipment after operability improves is disclosed.As an example of surface processing equipment, enumerated vacuum cleaner, this vacuum cleaner comprises: the roller assembling parts, it is positioned at the base portion of main body; And linkage, it is between handle and cleaning head.Linkage and cleaning head couple together in the mode freely swung on left and right directions (clockwise, counterclockwise) by bolster, linkage is configured to, and when roller assembling parts and handle are rotated centered by the axis of the long limit of handle, makes cleaning head to new directional steering.

Patent documentation 1: the flat 9-503398 communique of Japanese Unexamined Patent Application Publication (corresponding international publication number: WO95/01748)

Patent documentation 2: No. 4077823 communiques of Japan's special permission (corresponding international publication number: WO2004/014211)

Yet, the inventor is by studying discovery in great detail: in above-mentioned improvement technology in the past, because the shape difference of vertical floor-treating device, thus not only exist and can not fully improve the situation of its operability, and likely cause structure complicated of vertical floor-treating device.

Particularly, for example, (a) of Figure 13, the vacuum cleaner 510 that (b) of Figure 13 schematically shows, 520 respectively with the disclosed vacuum cleaner of patent documentation 1 or corresponding with the disclosed surface processing equipment of patent documentation 2, but, above-mentioned

vacuum cleaner

510, 520 is to communicate in the following areas, , the main body of dust collector 511 that above-mentioned vacuum cleaner 510 has column is called " bottom base " with the suction nozzle with battery unit 513(that is installed on the bottom of this main body of dust collector 511 in patent documentation 1, be called " cleaning head " in patent documentation 2), utilize central mouth bolster 517 this point so that the mode that supporting suction nozzle with battery unit 513 can swing with respect to main body of dust collector 511 supports suction nozzle with battery unit 513, the main body of dust collector 521 that above-mentioned vacuum cleaner has column is called " bottom base " with the suction nozzle with battery unit 523(that is installed on the bottom of this main body of dust collector 521 in patent documentation 1, be called " cleaning head " in patent documentation 2), utilize central mouth bolster 527 this point so that the mode that supporting suction nozzle with battery unit 523 can swing with respect to main body of dust collector 521 supports suction nozzle with battery unit 523.

In the vacuum cleaner 510,520 of this structure, all handle 514 by reversing top or arrow W1 or the arrow W2 in handle 524(figure) carry out the change direction of suction nozzle with battery unit 513 or suction nozzle with battery unit 523 via main body of dust collector 511 or main body of dust collector 521.In this case, the user is when reversing handle 514 or handle 524, the main body of dust collector 511 extended along the vertical direction or main body of dust collector 521 can swing significantly along the direction of rotation of left and right, therefore the weight of main body of dust collector 511 or main body of dust collector 521 is except forming centrifugal force, and the weight of main body of dust collector 511 or main body of dust collector 521 also can act on the hand of gripping handle 514 or handle 524.Therefore, the moment that acts on user's hand when changing direction becomes large, and hand can bear larger load, can feel thus effort when handle 514 or handle 524 change direction, its result, the operability in the time of can hindering the change direction.

In addition, in above-mentioned any one vacuum cleaner 510,520, when changing direction, for the stress that reverses the handle external force of 514,524 o'clock and handle 514,524, can concentrate on fulcrum 513a, 523a.Therefore, near the position this

fulcrum

513a, 523a requires to have the intensity that can stand above-mentioned external force and stress.Due in order to realize that higher intensity needs to construct accordingly or material, therefore likely can make the structure complicated of dust catcher.Particularly vacuum cleaner 520, and the bolster 527 by linkage links up by roller assembling parts 522 for main body of dust collector 521 and suction nozzle with battery unit 523, and therefore, external force and stress easily concentrate on this linkage and bolster 527.

And, in the vacuum cleaner 520 with roller assembling parts 522, take in suction in the inside of roller assembling parts 522 with air blast with for driving the motor (suction motor) of this suction with air blast.For example, if vacuum cleaner 520 is for being provided with the structure of rotating brush in the inside of suction nozzle with battery unit 523, because roller assembling parts 522 is connected with suction nozzle with battery unit 523 by linkage, thus textural at it, and above-mentioned suction can not be also used as with motor the motor that drives rotating brush.Therefore, need to be at the interior motor that is provided in addition specially rotating brush being rotated driving of suction nozzle with battery unit 523.That is, if the disclosed surface processing equipment of patent documentation 2 is dust catcher, will inevitably adopt two electric motor structures, thereby make the structure of dust catcher further complicated.

In addition, as shown in Figure 3, on deflecting roller 15, be provided with for cover this deflecting roller 15 above cover member 151.Be provided with cover fore paw 152 in the front portion of cover member 151.This cover fore paw 152 is the extended tabular positions, the place ahead towards cover member 151, if vacuum cleaner 10A is not for being used state, as shown in Figure 3, due to by main part (body shell body 11 and main body dust collecting part 12) is erected, can make to cover fore paw 152 and ground 100 butts, so the outer peripheral face of deflecting roller 15 can built on stilts 100.

Cover member 151 not only covers the top of deflecting roller 15, also supports the axis of rolling 153 of this deflecting roller 15.In addition, the top at cover member 151, be provided with wheel support axle 154 in the mode of freely rotating with respect to body shell body 11.The direction of this wheel support axle 154 is roughly consistent with the direction of the straight line that mouth bolster 13a and the axis of rolling 153 are linked up.Therefore, deflecting roller 15, to install by wheel support axle 154 and the mode that cover member 151 freely rotates with respect to body shell body 11, can change with respect to body shell body 11 angle of these deflecting rollers 15 thus.

In the vacuum cleaner 10A shown in Fig. 1～Fig. 3, the concrete structure of body shell body 11, main body dust collecting part 12, suction nozzle with battery unit 13, handle 14, deflecting roller 15, Handle axis 16 and secondary suction section (suction hose 133 etc.) is not particularly limited, and can suitably use known various structures in the field of vacuum cleaner.

For example, in the present embodiment, main part consists of body shell body 11 and main body dust collecting part 12, and body shell body 11 can separate with main body dust collecting part 12, but the structure that body shell body 11 and main body dust collecting part 12 also can be integrated.In addition, main part be take front surface and is formed as the mode that general curved face rear surface is the column of general planar face, but be not limited to this formation, it can be quadrangular shape roughly, such cylindricality gradually also can diminish towards top for sectional area, as long as be cylindricality on the whole, recess or protuberance can be set in side.

In addition, suction nozzle with battery unit 13 is substantially planar in the present embodiment, but is not limited to this shape, as long as suction nozzle with battery unit 13 has lower surface Su, it can be also the shapes such as hemispherical or housing shape.In addition, in the present embodiment, there is the handle 14 as grip part, but the shape of grip part is not limited to this, also can uses handle 14 known grip part in addition.

In addition, in the vacuum cleaner 10A shown in Fig. 1, in the inside of main part (being particularly body shell body 11), there is suction motor 223 and driven and the suction drum blower fan (not shown) of rotation by suction motor 223, there is rotating brush 131 in suction nozzle with battery unit 13.In this structure, the mode of extending towards this suction nozzle with battery unit 13 with the mouth bolster 13a from for supporting suction nozzle with battery unit 13 arranges the rotating shaft of suction motor 223, also can adopt the structure rotating shaft of this suction motor 223 and rotating brush 131 linked up by the band grade.If adopt this structure, can utilize suction motor 223 to drive suction drum blower fan and rotating brush 131, single suction motor 223 can be also used as to above-mentioned drive source thus.Therefore, can also simplify the structure of vacuum cleaner 10A.

In addition, the concrete structure for the mouth bolster 13a that suction nozzle with battery unit 13 is supported on to main part also is not particularly limited.In the present embodiment, as mentioned below, for suction nozzle with battery unit 13, the mouth bolster 13a of pair of right and left is set on the position clamped by the bottom to main part, thereby so that the mode that suction nozzle with battery unit 13 freely swings with respect to this main part supports suction nozzle with battery unit 13, but mouth bolster 13a can be both the structure that is provided with a bolster of the bottom of running through main part, can not also axle but the such frame for movement of Bearning mechanism.

That is, as long as mouth bolster 13a is located at the bottom of main part, and support suction nozzle with battery unit 13 so that suction nozzle with battery unit 13 can change the mode swung on the direction of angle of lower surface Su at the bearing of trend with respect to this main part, mouth bolster 13a can be also any structure.In addition, if floor-treating device is the structure beyond vacuum cleaner 10A, as long as the handling part bolster corresponding with mouth bolster 13a, so that the mode that floor treatment section can swing supports the ground handling part, just can adopt known various structure.

In addition, being located at the cover member 151 of deflecting roller 15 and the concrete structure of cover fore paw 152 also is not particularly limited.In the present embodiment, cover member 151 is configured to the roughly the first half that covers on the whole deflecting roller 15, still, for example, the structure that cover member 151 also can expose for the upper surface side that only covers deflecting roller 15.In addition, cover fore paw 152 is tabular in the present embodiment, still, for example, also can make the front portion of covering member 151 be configured to bulk, and the part setting in this front portion is equivalent to cover the such ground bearing surface of fore paw 152.In addition, many conditions such as the installation site of the length of cover fore paw 152 when to body shell body 11, deflecting roller 15 being installed and suitably setting, be not limited to specific length.

Turn to the structure of linking part

Next, not only with reference to Fig. 3, also (c) and (a) of Fig. 5, (b) of Fig. 5 with reference to (a)～Fig. 4 of Fig. 4 specifically describes the more specifically structure that turns to linking part 60A that vacuum cleaner 10A has.

As mentioned above, Handle axis 16 and deflecting roller regulating shaft 161 have formed and have turned to linking part 60A, and, as shown in Fig. 4 (a), be connected with deflecting roller regulating shaft 161 and rotate transfer part 160 and also formed and turn to linking part 60A.

Particularly, as shown in Figure 3, the upper end of deflecting roller regulating shaft 161 in the part as turning to linking part 60A, be provided with handle 14 by Handle axis 16, and as shown in Fig. 4 (a), in the lower end of deflecting roller regulating shaft 161, be provided with cam part 162, and this cam part 162 links by arm 163,164 and a pair of deflecting

roller

15,15.

Cam part 162, arm 163,164 are respectively elongated plate-like.Be fixed with the lower end of deflecting roller regulating shaft 161 at an end (rear end) of cam part 162, an end of arm 163 and arm 164 is installed at the other end (front end) of cam part 162.The other end of arm 163,164 is installed on respectively the cover fore paw 152 of cover member 151.Cover member 151 is not only the member that covers the top of deflecting roller 15, and is configured for by cam part 162 and arm 163,164 the rotation transfer part 160 linked between the lower end of deflecting roller regulating shaft 161 and deflecting roller 15.

Position relationship with regard to deflecting roller regulating shaft 161, cam part 162, arm 163,164 and deflecting roller 15, deflecting roller regulating shaft 161 is positioned at the inside of body shell body 11 as shown in Figure 3 along the vertical direction, be fixed with the rear end of cam part 162 in the lower end of deflecting roller regulating shaft 161, therefore, the cam part 162 of elongated plate-like is configured to and axially the intersecting of deflecting roller regulating shaft 161.In addition, if take the position of cam part 162 is benchmark, the position configuration of arm 163,164 is for to intersect at the front end place of cam part 162 and the long side direction of this cam part 162.Cam part 162 is positioned at by the position of two deflecting rollers, 15 clampings, and the configuration direction of cam part 162 and the configuration direction of deflecting roller 15 are arranged in the mode that forms almost parallel.

Here, on arm 163,164, be called the inner if will be installed on the end of the front end of cam part 162, the end that is installed on cover fore paw 152 is called to outer end, inner and mounting structure outer end all is preferably the structure (insert structure) that its jut can insert opening.For example, the cutaway view at the position that (b) of Fig. 4 surrounded by the circle of the dotted line as Fig. 4 (a), but as shown in the drawing, be formed with through hole 162a at the front end of cam part 162, be inserted with the jut 163b of the inner lower surface of being located at arm 163 in this through hole 162a.And, be formed with hole 163a at the upper surface of jut 163b, be inserted with the jut 164b of the inner lower surface of being located at arm 164 on this in the 163a of hole.Mounting structure between the outer end of arm 163,164 and cover fore paw 152 too, is inserted with jut 163c, the 164c of the outer end lower surface of being located at arm 163,164 in the through hole (not shown in (a) at Fig. 4) that is formed at cover fore paw 152.

In addition, as mentioned above, the top quilt cover member 151 of deflecting roller 15 covers, and is provided with cover fore paw 152 in the front portion of this cover member 151, and the outer end of arm 163,164 is installed at these cover fore paw 152 places.And, the axis of rolling 153 of cover member 151 supporting deflecting rollers 15, and at the upper surface of cover member 151, wheel support axle 154 is installed.If wheel support axle 154 is installed on to body shell body 11,, as shown in arrow R3, cover member 151 and deflecting roller 15 can be rotated centered by this wheel support axle 154.

Here, a pair of deflecting

roller

15,15 is in the bottom of body shell body 11, along the direction of the direct of travel M quadrature with suction nozzle with battery unit 13, is arranged in row.Particularly, as the left hand view in the Fig. 4 towards paper (c) institute schematically, if observe the bottom of body shell section 11 from the back side, in figure, deflecting roller 15-1, the 15-1 shown in solid line is located at paired position with the state that clamps this body shell body 11.Therefore in addition, during towards paper, the figure on the left side of Fig. 4 (c) and right side is the rearview of vacuum cleaner 10A, along the direction of going to opposite side the outside of the paper from accompanying drawing, is direct of travel M.

In addition, due to plural deflecting roller 15 also can be set, therefore, for example, also can be adjacent to arrange by the inboard with a pair of deflecting roller 15-1,15-1 deflecting roller 15-2, the 15-2 shown in dotted line and form the structure with 4 deflecting rollers 15 of total.Perhaps, both can arrange by the position of the middle at deflecting roller 15-1,15-1 by the deflecting roller 15-3 shown in the single-point line and form and there is the structure that adds up to 3 deflecting rollers 15, also can form the structure with 5 deflecting rollers 15 of total by whole deflecting roller 15-1～15-3 is set.

By this structure, if deflecting roller regulating shaft 161, cam part 162, arm 163,164 and deflecting roller 15 are linked up respectively, deflecting roller regulating shaft 161 and cam part 162 link with the state of fixing, and the outer end of inner and cover fore paw 152 and the arm 163,164 of the front end of cam part 162 and arm 163,164 links with the state be not completely fixed, a pair of deflecting

roller

15,15 is rotatably installed on the bottom of body shell body 11.

Therefore, as long as the user is reversed the operation of handle 14, the change in location of reversing the handle 14 that (rotations) produce can be delivered to Handle axis 16 and deflecting roller regulating shaft 161, and as shown in Fig. 4 (a) and Fig. 5 (a), deflecting roller regulating shaft 161 is understood and be rotated along the direction shown in arrow R 1.This rotation can further be delivered to cam part 162, thereby, as shown in Fig. 5 (a), the front end of cam part 162 for example can move to the position of double dot dash line from the position of solid line.Thus, the direction of intersecting along the long side direction with cam part 162 due to arm 163,164 swings, and the deflecting roller 15 therefore linked by cover member 151 and arm 163,164 can rotate along the direction of arrow R3.Its result, as shown in Fig. 5 (a), make the Angulation changes of deflecting roller 15.

In addition, as long as a pair of deflecting

roller

15,15 arranges along the direction with direct of travel M quadrature, just can make the change direction of the direction of twist operation of handle 14 and suction nozzle with battery unit 13 directly corresponding.Therefore, can also avoid generation to be difficult to grasp the possibility that changes nyctitropic operation.And, in a plurality of deflecting rollers 15 are arranged in the structure of row, as long as be configured to the user, by operating grip 14, make whole deflecting roller 15 carry out the angle variation towards same direction, just can utilize a plurality of deflecting rollers 15 effectively to limit the direct of travel M of suction nozzle with battery unit 13.

In addition, in the present embodiment, due to the mounting structure of cam part 162, arm 163,164 and the cover fore paw 152 such insert structure shown in (b) that is Fig. 4, therefore can also give the free degree to the concrete structure of cam part 162 and arm 163,164.For example, equally, in the situation that due to the difference of the concrete structure of body shell body 11 and suction nozzle with battery unit 13 need will be longer tabular component as cam part 162, as shown in Fig. 5 (b), can change by the movement that adopts insert structure to make arm 163,164 suitably follow the front end of cam part 162 angle of deflecting roller 15.

In addition, the concrete structure of deflecting roller regulating shaft 161, cam part 162, arm 163,164 is not particularly limited, can, according to the concrete structure of vacuum cleaner 10A or purposes etc., in the field that can apply same mechanism, can suitably adopt known shape, size, material etc.In addition, same, explanatorily such in embodiment 2 or embodiment 3 as described later, turn to the concrete structure of linking part 60A also to be not limited to there is deflecting roller regulating shaft 161, cam part 162 and arm 163,164.

For example, in the present embodiment, because being configured to by Handle axis 16, deflecting roller regulating shaft 161 transmits the change in location by the torsion generation of handle 14, therefore, as long as adopt the material or the shape that there is durability or rigidity with respect to twisting resistance, just can suitably use the deflecting roller regulating shaft of any kind.In addition, in the situation that deflecting roller regulating shaft 161 is to have the structure of durability or rigidity with respect to twisting resistance, cam part 162 or arm 163,164 or the two member preferably adopt has flexible material or shape.Thus, for example, at deflecting roller 15, because being subject to resistance from ground 100 etc. when between the wheel support axle 154 of this deflecting roller 15 and deflecting roller regulating shaft 161, having produced the changing of the relative positions in degree of rotation, can cushion this changing of the relative positions.

The structure of deflecting roller

Next, not only, with reference to Fig. 4 (c), also with reference to (a) of Fig. 6, (b) of Fig. 6, specifically described the concrete structure of the deflecting roller 15 that turns to linking part 60A to have.

The concrete shape of deflecting roller 15 is not particularly limited, but the shape of this deflecting roller 15 more preferably its outer peripheral face edge part smooth or its outer peripheral face is more outstanding than central portion on the whole.For example, as shown in Fig. 6 (a), used by the axis of rolling 153(axle center of deflecting roller 15) cross sectional shape be rectangular common wheel 15a roughly.On the other hand, for example, as shown in Fig. 6 (b), also can use the wheel 15b that cross sectional shape is double-peak shape.

The structure of common wheel 15a is not particularly limited, as long as its outer peripheral face is smooth on the whole.In addition, the concrete structure of the wheel 15b of double-peak shape also is not particularly limited, as long as wheel 15b is that the edge part by making its outer peripheral face is than the shape of two protuberances of the outstanding formation of the cross section at outer peripheral face of central portion, outstanding degree etc. is not particularly limited.In addition, the whole cross section that axle 153 passes that is scrolled of wheel 15a and wheel 15b consists of homogenous material, but be not limited to this, for example, wheel 15a and wheel 15b can be both the axis of rolling 153 neighbouring, be that the roll center of

wheel

15a, 15b is near metal-made and be resinous structure outer peripheral face, wheel 15a and wheel 15b also can be for inside the structure of hollow.That is, shown in (a) of Fig. 6, (b) of Fig. 6, the shape of

wheel

15a, 15b may not be limited to by the cross sectional shape of axle center (axis of rolling 153), as long as make the projection of shape (cross sectional shape of profile) with respect to direct of travel M, is illustrated shape.

Wheel 15a or wheel 15b are such is shaped as following shape: when this

wheel

15a, 15b are the state of inclination, can the relative position of the axis of rolling of this deflecting roller 15 153 be maintained to higher position by edge part and ground 100 butts that make deflecting roller 15.; as shown in the upper figure of Fig. 6 (a), Fig. 6 (b); if when

wheel

15a, 15b are common posture, the height apart from ground 100 of the axis of rolling 153 is made as to Hw1; as shown in the figure below of Fig. 6 (a), Fig. 6 (b); after

wheel

15a, 15b tilt, in posture, the height H w2 on the top in the axis of rolling 153 after inclination is higher than Hw1.

In addition, as shown in left hand view as towards paper the time in Fig. 4 (c), in the structure with two～five a plurality of like this deflecting rollers 15, whole deflecting rollers 15 can be both common wheel 15a, can be also the wheel 15b of double-peak shape, can also mixedly contain these

wheels

15a, 15b.

In addition, the right part of flg institute as towards paper the time in Fig. 4 (c) schematically, as deflecting roller 15, also can replace

wheel

15a, 15b and use roller 15c.The transverse width of the outer peripheral face of

wheel

15a, 15b is less than the diameter of

wheel

15a, 15b, and still, the shared ratio of the transverse width of the outer peripheral face of roller 15c becomes large.In this case, can further increase at deflecting roller 15 to tilt and the relative position of the axis of rolling 153 of deflecting roller 15 while making the edge part of deflecting roller 15 and ground 100 butt.Like this, in the present invention, as deflecting roller 15, it can make suction nozzle with battery unit 13 move, and, as long as deflecting roller 15 can utilize the operation of handle 14 to be changed direction, just can suitably use the rotary body of any shape.

In addition, at deflecting roller 15, in posture at a slant, if the relative position of the axis of rolling 153 becomes higher, also can make the relative position of mouth bolster 13a uprise.Because mouth bolster 13a is positioned at the rear portion of suction nozzle with battery unit 13, therefore can make the front portion of suction nozzle with battery unit 13 reduce, as mentioned below, when main part is maintained to the state of approximate horizontal, can compensate reducing of being adjacent to property between suction nozzle with battery unit 13 and ground.

In the present invention, as wheel 15a, the 15b of deflecting roller 15 or the concrete structure of roller 15c, be not particularly limited, but at least outer peripheral face of above-mentioned

wheel

15a, 15b or roller 15c preferably consists of elastomeric material.As elastomeric material, particularly, such as listing: the rubber such as SBR styrene butadiene rubbers, butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber, EP rubbers, butyl rubber, polyurethane rubber, silicon rubber, fluorubber (elastomer) material or cork (cork) etc., but be not particularly limited.

Above-mentioned elastomeric material, as long as at least be applied to outer peripheral face, still, can be also that the most of or whole deflecting roller 15 that comprises outer peripheral face of deflecting roller 15 consists of elastomeric material.For example,, as long as the part kept for the axis of rolling 153 of rotatably mounted deflecting roller 15 is that the metal larger by rigidity or resin material form and the part beyond this is to consist of elastomeric material.

Like this, in deflecting roller 15, as long as at least the outer peripheral face of its deflecting roller 15 consists of elastomeric material, the face of ground 100 and elastomeric material can butt.Therefore, regardless of state or the material on ground 100, all can effectively suppress deflecting roller 15 such possibility of skidding on ground 100.Therefore, can further improve the operability of vacuum cleaner 10A.

The example of vacuum cleaner

Next, for the representational example of the vacuum cleaner 10A of present embodiment, together with elemental motion and the method for operating of vacuum cleaner 10A, with reference to (c) and Fig. 7～Fig. 9 of Fig. 6, be specifically described.

At first, as shown in the left hand view as towards paper the time in Fig. 7, if vacuum cleaner 10A is not for being used state, the state of main part (body shell body 11 and main body dust collecting part 12) in erecting.It is identical with the state shown in Fig. 3 that this erects state, and deflecting roller 15 is anterior low and Gao De position, rear portion because erecting of main part remains on.This be because: the bottom of being located at body shell body 11 for the wheel support axle 154 that supports deflecting roller 15 in the rotating mode of deflecting roller 15, be positioned at the position at the oblique rear of mouth bolster 13a, and the configuration direction of wheel support axle 154 is roughly consistent with the straight line that mouth bolster 13a and the axis of rolling 153 are linked up.

Because the front portion at deflecting roller 15 is provided with the cover fore paw 152 as the part of cover member 151, therefore, this cover fore paw 152 makes the outer peripheral face built on stilts 100 of deflecting roller 15 with ground 100 butts.In addition, because the axle center of the axis of rolling 153 is positioned at the oblique rear lower portion in the axle center of mouth bolster 13a, therefore, the relative position with respect to ground 100 of mouth bolster 13a is lower than the relative position with respect to ground 100 of the mouth bolster 13a under use state described later (state after main part tilts).

Here, because the front lower surface 13b of suction nozzle with battery unit 13 is positioned at the front portion of this suction nozzle with battery unit 13, therefore, the mouth bolster 13a of suction nozzle with battery unit 13 is positioned at rear portion.If the relative position step-down of mouth bolster 13a, the rear portion of suction nozzle with battery unit 13 can reduce, thereby the front lower surface 13b that is positioned at the front portion of suction nozzle with battery unit 13 can remain the heeling condition that rear portion becomes fulcrum and anterior floating.

When the user uses this vacuum cleaner 10A, as shown in the right part of flg of Fig. 7, make the main part tilted rearward as towards paper the time.This heeling condition is the use state.That is, user's gripping handle 14 grades make main part tilt along the direction shown in arrow C in figure 1.Thus, the position of deflecting roller 15 is mobile to the roughly below of mouth bolster 13a, and the front portion of cover member 151 is lifted then subordinate and fallen, thus, as shown in arrow C in figure 2, with the cover fore paw 152 of ground 100 butts, be moved upward, the deflecting roller 15 that is positioned at top moves downwards.Its result, the outer peripheral face of deflecting roller 15 and ground 100 butts, therefore, vacuum cleaner 10A can utilize deflecting roller 15 to be moved on ground 100.In addition, the angle of inclination of main part (main body inclination angle) As is not particularly limited, and still, usually, as long as in the scope of 40 °～50 °, is preferably about 45 °.

In addition, under heeling condition, with the state of erecting, compare, mouth bolster 13a is moved upward (with reference to the poor Df shown in the single-point line in figure) with respect to 100De position, ground.As shown in arrow C in figure 3, the rear portion that is positioned at the suction nozzle with battery unit 13 of relative below can be moved upward thereupon.Now, the front lower surface 13b of suction nozzle with battery unit 13 on the whole with ground 100 butts.

More specifically, as shown in Fig. 8 (a), erecting under state, the place ahead of the front lower surface 13b of suction nozzle with battery unit 13 is towards tilting, and makes angulation α between the front lower surface 13b of suction nozzle with battery unit 13 and ground 100.In addition, for the ease of distinguishing with main body inclination angle As, this angle [alpha] is called " lower surface inclined angle alpha ".Under this state, as mentioned above, due to cover fore paw 152 and ground 100 butts, therefore make the outer peripheral face built on stilts 100 of deflecting roller 15.Then, when when erecting state and change to heeling condition, because the position of mouth bolster 13a is moved upward, the rear portion of suction nozzle with battery unit 13 is moved upward, so the mode that the front lower surface 13b of suction nozzle with battery unit 13 also can lift with its rear move.Its result, as shown in Fig. 8 (b), because the lower surface inclined angle alpha of having eliminated between front lower surface 13b and ground 100 makes front lower surface 13b become roughly consistent position relationship with ground 100, thus this front lower surface 13b on the whole with ground 100 butts.

And, in (b) (with the heeling condition of Fig. 7) of Fig. 8, because cover fore paw 152 is moved upward outer peripheral face and ground 100 butts that make deflecting roller 15 in the mode that reaches the approximate horizontal state, therefore suction nozzle with battery unit 13 can be moved by deflecting roller 15, and be located at suction nozzle with battery unit 13 front portion rotating brush 131 can with ground 100 butt fully.Its result, the use posture that can make vacuum cleaner 10A be converted to can be cleaned.

Afterwards, user's operating power switch 129 makes suction motor 223(with reference to Fig. 1) work.Thus, the air pressure of the inside of main body dust collecting part 12 (dust storage chamber) reduces and produces suction force via suction hose 133 at suction nozzle with battery unit 13 places.Then, the user can make suction nozzle with battery unit 13 move and be cleaned to the direction of hope by gripping handle 14.

Here, when the user wants to carry out the change direction of suction nozzle with battery unit 13, as shown in Figure 9, as long as reversed the operation of handle 14 along the direction of arrow R1.Thus, the change in location produced by the torsion (rotation) of handle 14 be delivered to cam part 162 via Handle axis 16 and deflecting roller regulating shaft 161 and the front end that makes cam part 162 to the left and right direction swing, thereby by arm 163,164, the angle of a pair of deflecting roller 15 is changed.For example, in Fig. 9, if towards paper to the right (clockwise) reverse handle 14, can in the situation that the angle that does not make the whole main part of vacuum cleaner 10A move to make deflecting roller 15 to the direction (towards the right side of paper) of arrow M1, change.Therefore, for the user, can make suction nozzle with battery unit 13 be easy to move to the direction of arrow M1, and without making handle 14 swing significantly and can not experience sense of heaviness ground operating grip 14.Similarly, if towards paper to the left (counterclockwise) reverse handle 14, can make the angle of deflecting roller 15 to the direction of arrow M2 (towards the left of paper to) change, therefore can make suction nozzle with battery unit 13 be easy to move to the direction of arrow M2.

Like this, only depend on operating grip 14 that the direction of deflecting roller 15 is changed, just can make 13 of suction nozzle with battery unit adipping in the situation that does not change angle move.Therefore, for example, even, in the situation that the wall towards the place ahead carries out cleanly, also the place ahead of suction nozzle with battery unit 13 can be maintained with respect to the parallel position of wall and change successively clean zone.Therefore, with vacuum cleaner in the past, compare, for example, the zone in the corner in clean room easily, and also needn't change the direction of suction nozzle with battery unit 13 itself when changing direction, thereby, even ground 100 is carpet, the resistance from ground 100 that also can reduce to be subject to when changing direction.

In addition, in the present embodiment, due to the De Xie rear, bottom of deflecting roller 15 being located to main part, therefore, and deflecting roller 15 is located to the place ahead compares, can simplify the structure that turns to linking part 60A, and, as shown in Figure 7, only depend on and make main part for erecting state, just can make the outer peripheral face built on stilts 100 of deflecting roller 15.; because being set to take mouth bolster 13a, suction nozzle with battery unit 13 with respect to main part, swung as axle; therefore; if by mouth bolster 13a be made as fulcrum, the handle 14 that will be positioned at the top of main part is made as the dynamic action point and deflecting roller 15 is made as to the drag effect point, the distance from fulcrum (mouth bolster 13a) to dynamic action point (handle 14) is greater than the distance from fulcrum (mouth bolster 13a) to drag effect point (deflecting roller 15).Therefore, because the user only erects main part with less power gripping handle 14, will make to be positioned near the outstanding cover fore paw 152 of drag effect point (deflecting roller 15) and move to the below of deflecting roller 15, can make thus deflecting roller 15 be easy to built on stilts.

In addition, if the front lower surface 13b that is positioned at forefront in lower surface Su is made as to inclined plane, the rear portion that is suction nozzle with battery unit 13 as the mouth bolster 13a of fulcrum can move down, so the front portion of suction nozzle with battery unit 13 can relatively move up.Therefore, can under heeling condition, make the front lower surface 13b built on stilts 100 with ground 100 butts.Due to rotating brush 131 forwardly lower surface 13b expose, therefore by the size of lower surface inclined angle alpha or the position of rotating brush 131, can keep in the mode that does not make rotating brush 131 itself contact with ground 100, rotating brush 131 certainly.

In addition, as shown in Figure 9, the locational pair of right and left mouth bolster 13a supporting that suction nozzle with battery unit 13 is clamped by the bottom of being located at main part (being body shell body 11 in Fig. 9) freely swings with respect to this main part.Therefore, with improvement technology (with reference to (a) of Figure 13, (b) of Figure 13) in the past, compare, in the situation that do not use special material etc., can utilize simple structure to seek to promote the installation strength of suction nozzle with battery unit 13 with respect to main part.Therefore, can avoid expensiveization of vacuum cleaner 10A.

In addition, as shown in Figure 8 (c), for example, inferior narrower when regional on above-below direction at clean furniture or bed, if main part is maintained to approximate horizontal, the position of deflecting roller 15 can be moved to the place ahead of mouth bolster 13a.With to erect state identical, under this state (being called the lodging state), due to the relative position of the mouth bolster 13a relative position lower than the mouth bolster 13a under heeling condition, therefore, with heeling condition (double dot dash line in figure), compare, the rear portion of suction nozzle with battery unit 13 can reduce.

For example, as shown in Fig. 8 (a), be made as height H s1 if will erect the position of the vertical of the mouth bolster 13a under state, and as shown in Fig. 8 (b), the position of mouth bolster 13a under heeling condition is made as to height H s2, and height H s2 is apparently higher than height H s1.In addition, as shown in Figure 8 (c), if make main part be made as the lodging state, the position of mouth bolster 13a is near erecting the height H s1 under state.Under the lodging state, the position of mouth bolster 13a is not in full accord with height H s1, but can make mouth bolster 13a roughly be positioned at height H s1.

And, if main part is the lodging state, deflecting roller 15 can be positioned at the below of suction nozzle with battery unit 13 and be positioned at the place ahead of mouth bolster 13a, therefore, suction nozzle with battery unit 13 maintains the state that can move by deflecting roller 15.Therefore, though on above-below direction narrower zone, also can only depend on main part is reduced for the lodging state makes the integral position of suction nozzle with battery unit 13, thus cleaning floor 100 suitably.

And, in vacuum cleaner 10A, if the wheel 15b that deflecting roller 15 is common wheel 15a or double-peak shape, more preferably with lodging state the main consuming body section.Particularly, as shown in Figure 8 (c), if main part is heeling condition (meaning with the double dot dash line in figure), deflecting roller 15 is positioned at the roughly below (while is with reference to Fig. 8 (b)) of mouth bolster 13a, but, when main part is changed to the lodging state when (meaning with the solid line in figure), the position of mouth bolster 13a can move to than heeling condition on the lower.Thus, the front portion of suction nozzle with battery unit 13 is lifted a little, therefore with erect state (with reference to (a) of Fig. 8) similarly, this anterior leading edge of being located at the place ahead lower surface 13b becomes such state that floats a little.

Like this, when main part is the lodging state, if observe the position relationship of main part, suction nozzle with battery unit 13 and deflecting roller 15 from the side of handle 14, as shown in Fig. 6 (c), main part (body shell body 11 and main body dust collecting part 12) and suction nozzle with battery unit 13 not only are configured to respectively approximate horizontal, and handle 14 and Handle axis 16 also are configured to approximate horizontal (with dotted line in figure, meaning Handle axis 16).Yet, under this lodging state, as shown in Figure 8 (c), because wheel support axle 154 becomes the heeling condition as shown in dotted line Sx2 in figure, therefore make deflecting roller 15 tilt with respect to ground 100.

; as shown in the dotted line Sx1 in Fig. 8 (c); because wheel support axle 154 is configured to roughly consistent with the straight line that mouth bolster 13a and the axis of rolling 153 are linked up; therefore; if main part is heeling condition, wheel support axle 154 maintains substantially vertical state (while is with reference to Fig. 8 (b)).Therefore, under heeling condition, the user can only make the direction of deflecting roller 15 change by operating grip 14, can not produce the inclination of deflecting roller 15 with respect to ground 100.On the other hand, if main part is the lodging state, the bearing of trend of wheel support axle 154 can become the heeling condition shown in dotted line Sx2 from the substantially vertical state variation shown in dotted line Sx1.

Like this, at wheel support axle 154, be under heeling condition, as shown in Fig. 6 (c), if the user is reversed the operation of handle 14,, when turning to linking part 60A that the direction of deflecting roller 15 is changed, this deflecting roller 15 can tilt with respect to ground 100.Due to the deflecting roller 15 wheel 15b that is common wheel 15a or double-peak shape, so the edge part of this deflecting roller 15 and ground 100 butts.

Here, under the state that does not reverse handle 14, as shown in the double dot dash line in Fig. 6 (c), the position at the rear portion of this handle 14, deflecting roller 15 and suction nozzle with battery unit 13 is relatively low position.On the other hand, when reversing handle 14, as shown in the solid line in Fig. 6 (c), due to the relative position of deflecting roller 15 only the height H w2 shown in (b) of (a), Fig. 6 of lifting height Hu(Fig. 6 and the difference of height H w1), so the relative position of mouth bolster 13a also rises.

Thus, make on the rear portion of suction nozzle with battery unit 13 to rise and make anterior decline, therefore can effectively relax the state that the leading edge of the place ahead lower surface 13b shown in (c) of Fig. 8 floats slightly.Therefore, due to the lower surface Su(that has improved suction nozzle with battery unit 13 with reference to Fig. 7) with respect to the being adjacent to property (butt) on ground 100, thereby, even be under the lodging state at main part, also can effectively suppress the low of the swabbing action that produced by suction nozzle with battery unit 13.Therefore, even in the inferior such zone narrower on above-below direction of bed, Yi Bian only depend on operating grip 14 on one side to make vacuum cleaner 10A just move forward and backward suitably cleaning floor 100.Therefore, no matter main part for the heeling condition state that still lodges, all can realize good clean-up performance.

Variation

In the present embodiment, by making deflecting roller 15 built on stilts 100 erecting under state, thereby limited suction nozzle with battery unit 13(vacuum cleaner 10A under not use state) movement, but be not limited to this structure, for example, can be also by the structure of deflecting roller 15 lockings for deflecting roller 15 can not be rotated.In this case, when switching from heeling condition to the state that erects, also can automatically lock deflecting roller 15 by frame for movement or electric structure etc.

In addition, during position beyond deflecting roller 15 is located at the rear, bottom of main part, also can deflecting roller 15 be moved upward on the whole itself by frame for movement or electric structure etc., and make deflecting roller 15 built on stilts 100.

And, because the state that erects and the heeling condition (with reference to Fig. 7) of present embodiment is relative position relation, therefore, self-evident, the concrete angle that erects state and heeling condition is not particularly limited.Therefore, erecting under state, main part is not limited to right angle, and in addition, the concrete angle while changing to heeling condition also can suitably be set according to the concrete structure of vacuum cleaner 10A.The concrete angle of the lower surface inclined angle alpha of the front lower surface 13b that similarly, corresponding mode is set with the angle with heeling condition (with reference to (a) of Fig. 8) also without particular limitation of.

In addition, in the present embodiment, deflecting roller 15 is located at the rear, bottom of main part, but the position of deflecting roller 15 is not limited to this position, its both can the bottom for main part under, can be also the place ahead, bottom.For example,, in the situation that deflecting roller 15 is positioned at the place ahead, bottom of main part, as long as extension is set and arm 163,164 is installed on to this extension at the rear portion of cover member 151.That is arm 163,164, if rotate transfer part 160, by cam part 162 and arm 163,164, formed, as long as will cover the front portion of member 151 or the position at rear portion and the front end of cam part 162 and link up.

In addition, in the present embodiment, on deflecting roller 15, be equipped with the cover member 151, but for the protection of or the supporting deflecting roller 15 structure be not limited to this.If present embodiment, not only can utilize cover member 151 protection deflecting rollers 15, and this cover member 151 can also play a role as rotating the connecting elements that transfer part 160 and deflecting roller 15 couple together.And, cover the member 151 supporting axis of rolling 153 and on cover member 151 tops, wheel support axle 154 be set by use, can make deflecting roller 15 itself be supported on body shell body 11.Therefore; these two effects of increase that can realize protecting deflecting roller 15 and suppress the number of components; but; the supporting member of cover member 151, the connecting elements be connected from rotation transfer part 160 and deflecting roller 15 both can be respectively different members; cover member 151 also can be set, but the member that will be also used as connecting elements and supporting member is located at deflecting roller 15 and is replaced covering member 151.

In addition, in the present embodiment, rotating transfer part 160 consists of cam part 162 and arm 163,164, thus, the action that can utilize simple structure to transmit well deflecting roller regulating shaft 161 to a plurality of deflecting rollers 15, this rotation transfer part 160 is not limited to this structure, for example, so long as with and the turned position of deflecting roller regulating shaft 161 change accordingly deflecting roller 15 the mode of angle by the structure linked up between deflecting roller 15 and deflecting roller regulating shaft 16, just can suitably use known other structures.

In addition, in the present embodiment, be provided with two deflecting rollers 15, but be not limited to this quantity, the deflecting roller 15 more than 3 also can be set.And, except deflecting roller 15, also can be so that the rotary bodies such as wheel or roller face down the mode of surperficial Su the rotary bodies such as wheel or roller are set.Therefore in addition, due to deflecting roller 15, for limiting the direct of travel M of suction nozzle with battery unit 13, in the situation that be provided with a plurality of deflecting rollers 15, above-mentioned deflecting roller 15 preferably is arranged in row along the direction with direct of travel M quadrature.Thus, because the direction that twist operation and the suction nozzle with battery unit 13 of handle 14 changes is directly corresponding, thereby can avoid occurring miscellaneous possibility in changing nyctitropic operation.

And, comprise that the structure that turns to linking part 60A of rotating transfer part 160 is not limited to comprise the said structure of Handle axis 16, deflecting roller regulating shaft 161, turn to linking part 60A as long as be following structure: the user is by gripping handle 14 and with the handle 14 of angle torsion arbitrarily, thereby linking part 60A itself and the torsion (rotation) of handle 14 are rotated accordingly, change the angle of deflecting roller 15 by the variation of this rotation.For example, turning to linking part 60A can be also near the structure that makes Handle axis 16 extend to deflecting roller 15 and cam part 162 is directly fixed on to the lower end of Handle axis 16, can also be that Handle axis 16 is not set, but handle 14 directly is set above main part and handle 14 is directly fixed on to the structure of the upper end of deflecting roller regulating shaft 161.

In addition, as long as deflecting roller regulating shaft 161 is made as and can rotates with respect to main part (being body shell body 11 in the present embodiment), therefore, deflecting roller regulating shaft 161 also can be set to be incorporated in fully the shape of the inside of main part, also can be set to the shape that all or part of is exposed to the back side of main part.

In addition, in the present embodiment, Handle axis 16 and deflecting roller regulating shaft 161 are set to be rotated with respect to main part, and Handle axis 16 and deflecting roller regulating shaft 161 are equivalent to be fixed with in the top the turning cylinder of handle 14.For example, if Handle axis 16 is defined as to the first turning cylinder for being connected with handle 14, deflecting roller regulating shaft 161 can be defined as to the second turning cylinder.Here, turn to linking part 60A in present embodiment, as long as at least comprise a turning cylinder, therefore, as mentioned above, on the structure of vacuum cleaner 10A, as turning cylinder, as long as there is any axle in Handle axis 16 or deflecting roller regulating shaft 161, can suppress thus the increase of the number of components.

On the other hand, there is following situation: turn to linking part 60A by what have that combination handle axle 16 and deflecting roller regulating shaft 161 form, can be in the situation that basically do not change the structure of existing upright vacuum cleaner 10A and append to install and turn to linking part 60A.In this case, can improve the operability of vacuum cleaner 10A, and not need to be designed to complicated structure.

In addition, in the present embodiment, as floor-treating device, mode with illustration vacuum cleaner 10A has illustrated the present invention, but the present invention is not limited to this, as long as, for vertical and utilize floor treatment section to process the structure on ground, can be applicable to the dust catcher of any kind.For example, as other floor-treating device, can list with lower device etc.: ground grinding machine, its floor treatment section has the abrasive disk that ground is ground; The ground coating machine, its floor treatment section is coated with the liquid such as wax or coating earthward; And carpet cleaning machine, in the situation that ground is carpet, its floor treatment section is cleaned this carpet.

As mentioned above, as long as vertical floor-treating device of the present invention is following structure, this structure comprises: the main part of column; Floor treatment section, it has the lower surface relative with the ground as processing object, is installed in the bottom of aforementioned body section; Grip part, it is located at the top of aforementioned body section, for the user, grips; Deflecting roller, its be located at aforementioned body section bottom can with the position of above-mentioned ground butt, limit the direct of travel of above-mentioned floor treatment section for utilizing its angle; And turning to linking part, it is located between the above-mentioned grip part and above-mentioned deflecting roller in aforementioned body section, is independent of the angle of aforementioned body section and the above-mentioned deflecting roller of above-mentioned floor treatment section ground change for the operation according to above-mentioned grip part.

Adopt said structure, the linking part that turns to of grip part and the deflecting roller main part by being located at column links up.Therefore, the user, can be in the situation that do not make whole main part move by turning to linking part to change the angle of deflecting roller by the operation grip part.Therefore, for the user, can make floor treatment section be easy to change direction, and can in the operation of grip part, not experience sense of heaviness.And, as long as owing to thering is the linking part that turns to that grip part and deflecting roller are linked up, and do not need separately setting operation section etc., therefore can effectively suppress structure complicated of floor-treating device.Therefore, in vertical floor-treating device, operability can be further improved, and structure complicated of vertical floor-treating device can be avoided.

In above-mentioned vertical floor-treating device, as an above-mentioned example that turns to linking part, can list following structure, this structure comprises: turning cylinder, it arranges in the mode that can rotate with respect to aforementioned body section, above-mentioned grip part end fixed thereon; And the rotation transfer part, it will link between the lower end of above-mentioned turning cylinder and above-mentioned deflecting roller, in order to change accordingly the angle of above-mentioned deflecting roller with the turned position with this turning cylinder.

Adopt said structure, form owing to turning to linking part by turning cylinder and rotating transfer part, therefore the action that grip part is rotated can be passed to deflecting roller and change the angle of this deflecting roller.Therefore, the operability of seeking to improve floor-treating device under complicated structure situation can not adopted.In addition, the floor treatment section because supportings such as can on the left and right directions of main part, utilizing handling part bolster described later is installed in the mode freely swung with respect to main part, therefore can seek to improve the installation strength of floor treatment section with respect to main part.

In addition, in above-mentioned vertical floor-treating device, above-mentioned deflecting roller is one, but also a plurality of deflecting rollers can be set, and in this case, preferably all above-mentioned deflecting rollers are arranged in row along the direction of the direct of travel quadrature with above-mentioned floor treatment section.

Adopt said structure, by a plurality of deflecting rollers are set, can improve the mobility of floor-treating device, and, if a plurality of deflecting rollers are arranged along the direction with the direct of travel quadrature, in the operational example of grip part when be twist operation, the direction that can make direction of operating and floor treatment section change is directly corresponding, thereby can also avoid producing, is difficult to grasp the possibility that changes nyctitropic operation.In addition, at a plurality of deflecting rollers, be arranged in the structure of row, as long as the user makes whole deflecting rollers carry out the angle variation towards same direction by the operation grip part, just can utilize deflecting roller effectively to limit the direct of travel of ground handling part.

In said structure, can list the above-mentioned rotation transfer part with following structure as a preferred example, be that above-mentioned rotation transfer part at least consists of cam part and arm, one end of this cam part is fixed in the lower end of above-mentioned turning cylinder, and this arm is for linking up the other end of this cam part and above-mentioned deflecting roller.

Adopt said structure, owing to transmitting well the action of turning cylinder to a plurality of deflecting rollers by the combination of cam part and arm, therefore can utilize simple structure to seek to improve operability.

In addition, in said structure, can list following structure: be provided with the cover member on above-mentioned deflecting roller, this cover member is for the turning cylinder of this deflecting roller of state support of the top to cover this deflecting roller, and above-mentioned arm is for linking up the position at the place ahead that is positioned at above-mentioned direct of travel of above-mentioned cover member or rear and the other end of above-mentioned cam part.

Adopt said structure; cover member by utilization and cover deflecting roller; not only can protect deflecting roller; can also make this cover member as playing a role for rotating the connecting elements that transfer part and deflecting roller couple together, thus these two functions of increase that can realize protecting deflecting roller and suppress the number of components.

In addition, above-mentioned vertical floor-treating device is preferably the structure that this deflecting roller is installed on aforementioned body section as follows: under the state made after aforementioned body section erects, the outer peripheral face built on stilts of above-mentioned deflecting roller, under state the rear side that makes aforementioned body section from the above-mentioned state erected to above-mentioned direct of travel tilts, the outer peripheral face of above-mentioned deflecting roller and above-mentioned ground butt.Particularly, as long as above-mentioned vertical floor-treating device is the structure that is provided with the cover member for covering deflecting roller, can enumerates the place ahead of this cover member of sening as an envoy to and give prominence to as thering is the structure of cover fore paw.

Adopt said structure, if main part is for erecting state, deflecting roller built on stilts and can not produce the floor treatment section situation of movement accidentally that makes.On the other hand, if the user grips grip part, main part is tilted, deflecting roller can with the ground butt, therefore can make floor treatment section for state movably.Like this, only depend on and main part is erected or tilt, just can switch to state or the use state of not using, therefore can further improve operability.

In said structure, also there is the handling part bolster, it is located at the bottom of aforementioned body section, for can make above-mentioned floor treatment section support above-mentioned floor treatment section changing the mode swung on the direction of above-mentioned lower surface with respect to the angle of the bearing of trend of this main part, above-mentioned deflecting roller more preferably is located at the position at rear of bottom, the direct of travel that be positioned at above-mentioned floor treatment section of aforementioned body section.

Adopt said structure, floor treatment section is set to take the handling part bolster and swings as axle and with respect to main part, and deflecting roller is positioned at the rear, bottom of main part.Therefore, as long as make in use main part tilt, just can so that the mode of the outer peripheral face of deflecting roller and ground butt make this deflecting roller be positioned at the handling part bolster roughly below, in addition, as long as when not using, main part is erected, just can make the outer peripheral face built on stilts of deflecting roller.Therefore, the user only grips grip part with less power and main part is erected just can make deflecting roller be easy to built on stilts or make the main part inclination just can make deflecting roller be easy to and the ground butt.

For example, as mentioned above, if having the cover fore paw, due to the state setting of floor treatment section to move freely with respect to main part, therefore, the user only grips grip part with less power erects main part, just can make deflecting roller be easy to built on stilts.; movable part being considered as to fulcrum, will be positioned at main part above grip part be considered as the dynamic action point and deflecting roller be made as to the drag effect point, from fulcrum to dynamic action, the distance of point (grip part) is greater than the distance of the point (deflecting roller) from fulcrum to drag effect.Therefore, the user only grips grip part with less power erects main part, and near cover body front portion outstanding drag effect point (deflecting roller) will be moved to the below of deflecting roller, therefore can make deflecting roller be easy to built on stilts.Therefore, needn't be in order to make the deflecting roller built on stilts or to make deflecting roller and ground butt and use complicated structure, thus can effectively avoid structure complicated of floor-treating device.

And, in the structure with above-mentioned handling part bolster, above-mentioned deflecting roller is its outer peripheral face edge part shape more outstanding than central portion of smooth or its outer peripheral face on the whole more preferably.

Adopt said structure, the position of the handling part bolster under the heeling condition of main part is higher than the position of the vertical that erects the handling part bolster under state, but, if main part is the lodging state, can make the position of handling part bolster near the position that erects state.And, if main part in the lodging state, deflecting roller can be positioned at the below of floor treatment section, and is positioned at the place ahead of handling part bolster, so floor treatment section maintains the state that can utilize deflecting roller to be moved.Therefore, though on above-below direction narrower zone, only depending on and making main part is the lodging state, also can reduce the integral position of floor treatment section, can suitably clean thus bed and wait the ground under furniture.

In addition, if deflecting roller forms its outer peripheral face smooth or edge part shape more outstanding than central portion on the whole, by operating grip under the lodging state, the edge part of deflecting roller is contacted with ground, can raise the handling part bolster.Therefore can effectively alleviate because main part becomes the front portion that the lodging state makes floor treatment section and become the possibility of the state of floating slightly, thereby can improve the being adjacent to property of floor treatment section with respect to ground.Its result, can carry out the movement of floor treatment position easily in the situation that effectively suppress the reduction of floor treatment effect.

And at least outer peripheral face of preferred above-mentioned deflecting roller consists of elastomeric material.

Adopt said structure, due to the outer peripheral face formed by elastomeric material and ground butt, therefore can effectively suppress deflecting roller such possibility of skidding on the ground.Therefore, can further improve the operability of floor-treating device.

The concrete structure of vertical floor-treating device of the present invention is not particularly limited, and the present invention can be applied to the floor-treating device of various kinds, but, as representational floor-treating device, can list vacuum cleaner as described above.As the concrete structure of this vacuum cleaner, for example, as mentioned above, can list following structure: main part has suction motor and dust storage chamber, and above-mentioned floor treatment section has rotating brush.

Embodiment 2

In above-mentioned embodiment 1, vacuum cleaner 10A has, and to turn to linking part 60A be the structure with Handle axis 16 and deflecting roller regulating shaft 161 and cam part 162, arm 163,164, but the example that turns to linking part of the structure with other is described with reference to Figure 10 and Figure 11 in the present embodiment.

As shown in figure 10, the vacuum cleaner 10B of the first structure example of present embodiment has the structure (the place ahead handle arrangement) that handle 14 and Handle axis 16 are positioned at the place ahead of main part.In this vacuum cleaner 10B, be provided with single dashdotted ellipse representation in figure for the protuberance 117(of the place ahead on the top of body shell body 17), be provided with handle 14 in the front upper surface of this place ahead protuberance 117 by Handle axis 16.

More specifically, the basic structure of body shell body 17 is identical with the body shell body 11 of above-mentioned embodiment 1, but directly over the housing in the upwardly extending position of upper and lower (corresponding with body shell body 11), be provided with integratedly with body shell body 17 the place ahead protuberance 117 extended towards oblique the place ahead, in the front upper surface of this place ahead protuberance 117, be provided with Handle axis 16.

In addition, with vacuum cleaner 10A similarly, be provided with deflecting roller regulating shaft 161 in body shell body 17, the place ahead protuberance 117 is between this deflecting roller regulating shaft 161 and Handle axis 16, the inside of protuberance 117 is provided with gear mechanism 165 forwardly.Gear mechanism 165 for example consists of the sector gear of the lower end of being fixed in Handle axis 16, the upper end gear and the idler gear between sector gear and upper end gear that are fixed in the upper end of deflecting roller regulating shaft 161.Thus, the operation (arrow R1 direction) that the user reverses by the handle 14 that carries out being positioned at the place ahead, thereby by Handle axis 16 and gear mechanism 165, the change in location of handle 14 is delivered to deflecting roller regulating shaft 161, makes this deflecting roller regulating shaft 161 rotate (arrow R1 direction).

Like this, because the vacuum cleaner 10B of the first structure example comprises the place ahead protuberance 117 at main part, therefore have by Handle axis 16, deflecting roller regulating shaft 161, gear mechanism 165 and rotate that transfer part 160 forms turn to linking part 60B.

Here, gear mechanism 165 as long as play a role as the parts (change in location transfer part) of the change in location that Handle axis 16 is connected transmit handle 14 with deflecting roller regulating shaft 161 in turning to linking part 60B, and, action when making handle 14 carry out change in location, action when in other words Handle axis 16 is rotated, parts (velocity of rotation speed changing portion) that gear mechanism 165 more preferably also increases or reduces as " speed " that can make this rotation and playing a role.

For example, although by reversing handle 14, Handle axis 16 is rotated with predetermined angular, but, if gear mechanism 165 can make this rotation " speed " increase, even the user reverses the degree less (changing less even reverse the angle produced) of handle 14, also can make by " speed changing function " of gear mechanism 165 velocity of rotation of Handle axis 16 increase, thereby can increase the angle variation of deflecting roller 15.Perhaps, if gear mechanism 165 can make velocity of rotation reduce, can reduce the needed power of torsion of handle 14, so the user can carry out the operation of handle 14 with more " little power ".
