Introduced in detail in addition in the application for patent of being mentioned in front: how brush roll 16 drives through electro-motor 52.

For supplying with electro-motor 52 electric energy, floor cleaning device 10 comprises the rechargeable battery 56 of two battery forms (for example lithium-ions battery form).Battery 56 remains on the handle rod shell lower component 30 by keeper 46, and therefore remains on the handle bar 20.Battery 56 is arranged in (Fig. 2) on the floor cleaning device 10 about the central longitudinal plane of floor cleaning device 10 with being mutually symmetrical.

For keeping battery 56, keeper 46 has first section 58.This first section 58 is arranged in the top of cleaning head 12, and holds place 60 for what each battery 56 had formed the pit shaft shape, this hold place 60 floor cleaning device 10 vertically on be disposed generally on the height of brush roll 16.Each hold place 60 its have on side of cleaning head 12 dorsad be used for battery 56, for the user, can introduce opening 62 with the upside that plain mode touches.Battery 56 can make things convenient for tool free ground, user ground to pack into to hold to locate in 60 through introducing opening 62.At this, battery 56 holds the screens mechanism 64 mutually screens of place in 60 with being arranged in, and is fastened on and holds in the place 60.

Battery 56 stretches out in the side of cleaning head 12 dorsad and holds place 60.After screens was unclamped, battery 56 can be taken out from holding in 60 with plain mode tool free ground by the user thus, for example so that battery 56 is delivered to outside and unshowned in the accompanying drawings charging station, to charge.

In gap 60, be furnished with contact element 66 in addition, utilize contact element 66 can battery 56 be electrically contacted connection, so that from battery 56, obtain electric energy.Contact element 66 effectively is connected with the electrical mechanisms 68 of floor cleaning device 10, and this contact element 66 is arranged in holding in the place 72 that another section 70 by keeper 46 forms.

Between first section 58 that vertically is arranged in keeper 46 relatively of portion's section 70 and floor cleaning device 10 and second section 74, this second section 74 constitutes above-mentioned the second half clamshells 44 of electro-motors 52 housing 42 used with aspirating unit 54.Portion's section 70 has formed the 3rd section of keeper 46 above cleaning head 12.Therefore, stretch out towards the direction of floor cleaning device 10 positive 78 in the space 76 (Fig. 5) that keeper 46 idiomorphisms are formed between container assemblies 34 and the cleaning head 12, particularly is to stretch out with the 3rd section 70 and first section 58 of being arranged in cleaning head 12 belows.

The 3rd section 70 hold the introducing opening 80 that place 72 has a upside.When assembling floor cleaning device 10, can electrical mechanisms 68 be introduced according to plain mode through introducing opening 80.Place 72 is held in sealing by lid 82 dust and water protections, avoids ectocine with protection electrical mechanisms 68.

Electrical mechanisms 68 effectively is connected with electro-motor 52 equally.Can control in the mode of the discharge in service of floor cleaning device 10 two batteries 56 through this electrical mechanisms 68, so that electric energy is provided to electro-motor 52.This point for example can be carried out as follows, at first makes 56 discharges of a battery that is:, and after this battery discharges fully, then makes 56 discharges of second battery.

Through battery 56 being used for to electro-motor 52 power supply, can in floor cleaning device 10, cancel required under other situation, to floor cleaning device 10 be connected in the cable on the supply network with it for energy supply.The advantage of doing so on the one hand is, floor cleaning device 10 is more promptly carried out to use than conventional floor cleaning device and prepared, and this is because the user will not be connected with supply network by cable when debugging.On the other hand, the range of movement of floor cleaning device 10 is compared with the conventional floor cleaning device to some extent and is enlarged, and has the cable that provides constraints that limits length because can cancel.

Another advantage of floor cleaning device 10 is based on the previous constructions scheme of keeper 46 and obtain, and here particularly explains with reference to Fig. 3 and 4.

As already mentioned, pivot axis 18 is through the middle heart trend of housing 42.Thus, pivot axis is surrounded at one side of something by second section 74 that forms half clamshell 44.First section 58 has a spacing with respect to second section 74.Therefore, battery 56 has a spacing with pivot axis 18.The front that vertically is arranged in pivot axis 18 relatively of battery 56 and floor cleaning device 10 particularly.

When debugging floor cleaning device 10, pivot by the user like carpopodium bar 20, and transfer in the run location, so the back that vertically reaches pivot axis 18 relatively of container assemblies 34 and floor cleaning device 10 around pivot axis 18.What cause like this is: particularly container assemblies 34 comprises that the clean liquid 37 that is contained in has wherein produced first tilting moment that acts on handle bar 20 with contaminated liquid 39.

On the conventional floor cleaning device, the user must react on this tilting moment at handgrip 22 places, continues to pivot towards the direction on the face of land around pivot axis 18 to prevent handle bar 20.The person of being used felt it is to disturb when this point was worked at the conventional floor cleaning device.

Here in foundation floor cleaning device 10 of the present invention, battery 56 produces second tilting moment.This second tilting moment is delivered on the handle rod shell lower component 30 that is connected with keeper 46 through keeper 46, and therefore is delivered on the handle bar 20.Thus, keeper 46 formations act on the lever arm on the handle bar 20.Second tilting moment that produces by battery 56 reacts on first tilting moment that particularly produces through container assemblies 34, because battery 56 is arranged in the front of pivot axis 18 on the run location of handle bar 20.

For the user, can feel the effect of second tilting moment as follows, that is: the user descends for handle bar 20 being remained on the load that on handgrip 22, must apply on the run location.This point feels comfortable for the user when utilizing 10 work of floor cleaning device, thereby this floor cleaning device is characterised in that very high handling comfort.In the ideal case, if first tilting moment and second tilting moment are offset then load even the complete obiteration on the handgrip 22 just.

Battery 56 remains on handle bar 20 on the bottom of cleaning head 12 by keeper 46, and keeper 46 is roughly erect from this bottom with meeting at right angles.Therefore, though battery and floor cleaning device 10 vertically relatively-at handle bar 20 horizontal alignments, when promptly being in the extension of cleaning head 12, still be arranged in the front of pivot axis 18.Therefore, in the very large angular range of different run locations between cleaning head 12 and the handle bar 20, in its run location, produce second tilting moment through battery 56.This point means, handle bar 20 can occupy a large amount of different from run locations different aspect the angle of pivot with respect to cleaning head 12, and on these run locations, second tilting moment reduces the influence that handgrip 22 places help handling comfort.

First section 58 and the 3rd section 70 constitute a common rest element 84 at it on the bottom side of cleaning head 12.Rest element 84 can be resisted against on the cover plate 86 of cleaning head 12 and particularly lie on the cover plate 86 of cleaning head 12 (Fig. 1 to 3) in the resting position of handle bar 20.Thus, on the resting position of handle bar 20, the weight of battery 56 is drawn out on the cleaning head 12 and reduces 46 application of loads of keeper.
