Description

Battery operated vacuum cleaner

The invention relates to a battery-operated vacuum cleaner, comprising a suction container, a suction head, which is arranged on the suction material container, a blower device for generating a suction flow and at least one process air duct, which is fluidly connected to the blower device. From WO 2012/107595 a vacuum cleaner is known, which has a battery device for supplying energy to the vacuum cleaner and for supplying energy to an external air valve device for cleaning a filter device. The invention has for its object to provide a battery-powered vacuum cleaner of the type mentioned, which is compact.

This object is achieved according to the invention in the battery-powered vacuum cleaner mentioned above in that a battery holder for a battery device is positioned on the suction head between the at least one process air duct and / or between at least one cooling air duct of the blower device and an upper side of the suction head.

By this positioning of the battery holder (and thus also held on the battery holder battery device), the suction head and thus the sucker can be made compact.

Basically, the top of the nipple with battery means held thereon may be defined by the battery means, or the top is defined by a member of the nipple which is not battery means, and a retained battery means is flush with or reset to the top. It can be achieved in a simple manner that the battery device does not protrude or only slightly beyond an outline region of the nipple and in particular of the suction head. The solution according to the invention makes it possible to achieve a space-saving and protected housing of the battery holder and the battery device on the suction head.

Furthermore, removal of the battery device or insertion of the battery device is possible in a simple manner.

It is provided in particular that the battery device is detachably held on the battery holder. To "housing" the battery device on the battery-operated vacuum cleaner, the "residual vacuum cleaner" outside the suction head does not have to be modified or only slightly modified.

Conveniently, the blower device is positioned on the suction head.

As a result, for example, good access to the suction material container can be achieved if the suction head as a whole is detachably arranged on the suction material container.

It is advantageous if a bow handle is arranged on the suction head, which defines an upper side of the suction head (without battery device). About this bow handle the sucker can be held and transported. In particular, the bow-shaped handle defines the uppermost region of the nipple as the region which has the greatest distance to a base on which the nipple is correctly set up.

It is advantageous if the battery holder is arranged and designed such that, in the case of the battery device held on the battery holder, the battery device does not protrude beyond the top of the suction head. This results a space-saving accommodation. It reduces the risk of injury to an operator or prevents an operator from "hanging" on an inserted battery device. Furthermore, the battery device can be "sunk" and thus protected on the battery holder and thus in turn positioned on the suction head.

It may be provided that the arranged on the battery holder battery device is flush with a bow handle. In particular, there is a flush transition to the bow handle. As a result, for example, the risk of pinching a finger between the bow handle and the battery device is prevented or greatly reduced.

It is particularly advantageous if an insertion direction and / or execution direction for the battery device on the battery holder is transverse and in particular perpendicular to an envelope plane of the upper side of the suction head. The battery device is in particular detachably held on the battery holder. The battery device, which is in particular rechargeable, can then be removed from the battery holder for recharging. Furthermore, the battery-powered vacuum cleaner can be operated with different battery devices, so that a longer suction time can be achieved. By the insertion direction or execution direction transverse to the envelope level, the battery device can be removed upwards

or be used from above. This results in an optimal use of space. Furthermore, the battery device can be aligned with a longer side parallel to the insertion direction or execution direction, so that here also an optimized use of space results and in particular no broadening of the suction head is necessary.

For the same reasons, it is favorable if the insertion direction and / or execution direction is at least approximately parallel to an axis of rotation of a blower motor of the blower device and / or is at least approximately parallel to a height direction of the suction material container. The height direction of the suction material container corresponds in particular, a direction parallel to a distance direction from the top to the suction material container.

Furthermore, it is alternatively or additionally advantageous for the same reasons, if the insertion direction and / or execution direction is transverse and in particular perpendicular to a roller axis of one or more rollers, via which the sucker is mobile mounted on a pad and / or at least approximately parallel to one Steering axis of one or more steerable rollers, via which the sucker is mobile mounted on a base and / or is transverse and in particular perpendicular to a longitudinal direction of a channel portion of the at least one process air duct, the channel section directly below the battery holder or the

Battery device is arranged on the suction head and the longitudinal extension direction corresponds to a main flow direction for a process air flow in the channel portion and / or at least approximately to a Aufsetzrichtung the suction head to the suction material container. The suction head is in particular detachably arranged on the suction material container and the placement device is at least approximately parallel to the insertion direction or execution direction.

At least approximately parallel is understood to mean that the orientation is parallel or at an acute angle of at most approximately 20 ° to the parallel. The channel section, which is arranged directly below (relative to a direction from the top to the suction material container) of the battery holder and / or the battery device on the suction head, is in particular a channel section, which is modified such that the battery device on the

Battery holder can be accommodated in a space-saving manner on the suction head.

It is advantageous if an open area is formed on the suction head, on which the battery holder is arranged, wherein the open area towards the top and / or open at least one side transversely to the top is. For example, it is open to a front. If the open area is open to the top, then the battery device can be inserted from there or lead out at the top. If the free area is open transversely to the upper side on at least one side and is open, for example, to a front side, then an improved gripping of the battery device can be made possible in order, for example, to remove it from the battery holder in a simple manner. Furthermore, displays on the battery device can be read more easily. It is particularly advantageous if a receiving area is formed on the free area and / or the free area forms a receiving area, wherein the battery holder is seated on the receiving area, and wherein the receiving area is limited by a bottom wall and rear wall oriented transversely to the bottom wall. Through this receiving area, which has, for example, the shape of a hollow cuboid, a receiving space for the battery device is formed. It can then accommodate the battery device to save space on the suction head.

It is particularly favorable when the back wall between the

at least one process air duct and the top is arranged. The

Rear wall can be used in particular to position parts and, for example, all parts of the battery holder on the suction head. For example, one or more guide rails or guide grooves can be positioned on the rear wall.

It is favorable if the bottom wall covers at least one channel section of the at least one process air channel. This results in a space-saving training and the suction head and thus the sucker can be made compact.

In one embodiment, the clearance is formed on a wall which is oblique to a direction from the top of the suction head to the suction material container. This allows the suction head to be edge-free or form low edge. On the other hand results in an optimal positioning for a battery device.

The inclined wall is then preferably formed so that a battery device used on the battery holder is partially immersed in a recess on the wall (formed over the free area), and is immersed in a part with respect to the oblique wall. At this immersed part, the battery device can be gripped and so removed from the battery holder in particular by a displacement movement.

In one embodiment, a switch is arranged on the wall and in particular arranged next to the battery holder and in particular outside of the free area. This results in an optimized use of space with ease of use of the teat. The switch is in particular an on-off switch. In addition, it is easy to keep the wiring for electrical cables to the suction head.

It is particularly advantageous when the battery holder is arranged with respect to the free area that a held battery device does not protrude laterally beyond the suction head. The side is relative to all surfaces which are oriented transversely to the top. This results in a space-saving accommodation. The risk of an operator hanging on to the battery device is minimized. Furthermore, there is no risk that the battery device may encounter a wall or the like during a suction operation.

It is also advantageous if the free area opposite the top of the suction head is open so that the battery device can be inserted from the top of the suction head to the battery holder. In particular, the battery device can be fixed on the suction head via a displacement movement in an insertion direction. It results in an optimized use of space with easier Removability or fixability of the battery device to the battery holder.

It is also favorable that the free area is laterally open so that an optical display on the battery device can be read when the battery device is inserted on the battery device. The corresponding open side is in particular a front side, which is opposite to a rear wall.

This results in a compact construction, if a suction connection for a suction hose is arranged on one side of the nipple, on which the battery holder is arranged.

Relative to a height direction of the suction material container then in particular the suction port and the battery holder are one above the other, and they do not necessarily have to be arranged in alignment in this direction. It is advantageous if this arrangement is not aligned, but the battery holder with the battery device with respect to a contour line, which goes through the suction port, is reset. In particular, the suction connection is arranged with respect to a direction from the top of the suction head to the suction material container below the battery holder, wherein in particular the suction connection is arranged on the suction material container. This results in a compact design. It is advantageous if a channel section of the at least one process air channel which is positioned directly below the battery holder and / or the battery device has a total height of at most 80 mm and in particular of at most 70 mm and in particular at most 65 mm. The total height is based on a direction which corresponds to a projection direction parallel to a height direction of the suction material container or a direction from the top side to the suction material container. The positioning directly below means that the channel section lies on the corresponding projection line. Through a Such a channel section with a relatively small overall height, the battery device can be positioned with its longer side parallel to said height direction. It is a space-saving positioning possible without the battery device protrudes beyond the top of the teat.

It is favorable if a channel section of the at least one process air channel, which is arranged directly below a direction from the top side of the suction head to the suction material container of the process air channel, is of multi-chambered or multi-part design. This results in a simple structure. For example, a lower part may be fluidly connected directly to a filter device (a clean side of a filter device) and, for example, a filter basket, while the upper part is closer to the blower device and is, for example, part of a motor console. It is particularly advantageous if at least one stage is formed on the at least one process air duct and / or on the at least one cooling air duct and / or on a transition from the at least one process air duct to the at least one cooling air duct. As a result, in particular, a channel section can be formed such that the battery holder and / or the battery device can be positioned directly above it. It can be kept low in this area an overall height, so that a space-saving accommodation of the battery holder with the battery device is possible.

In particular, then the at least one stage directly below the

Battery holder and / or held by a battery device based on a direction from the top of the suction head to the suction material container out. As a result, the battery device can be positioned to save space on the suction head. In particular, the battery device can be aligned with its longest side parallel to the direction mentioned from the top of the nipple to the suction material container. It can thereby be achieved in a simple manner that the battery device, when it is held on the battery holder, does not protrude beyond the top of the teat. Furthermore, it can be achieved in a simple manner that the Battery device does not protrude laterally beyond the sucker, since in particular their other lateral dimensions are smaller than on the longest side.

In one exemplary embodiment, a battery device held on the battery holder has a longitudinal axis which is at least approximately parallel to an axis of rotation of a blower motor of the blower device, wherein the battery device is arranged overlapping with the blower device with respect to this longitudinal axis. The longitudinal axis is in particular that axis in which the battery device has its greatest length. By overlapping with respect to the corresponding direction, the battery device can be positioned to save space on the suction head.

It is favorable when an overlapping length of the battery device or of the battery holder with respect to a total length of the battery device or the battery holder in the longitudinal axis mentioned at least 10% and preferably at least 20% and preferably at least 25% (and more preferably at least 30% and for example at least 40) %). This results in a space-saving arrangement. The battery device or the battery holder can be arranged above the overlap area next to the fan device or next to a partial area thereof.

It is also favorable if the battery holder is arranged and designed such that a center of gravity of a held battery device is located above a center of gravity of the vacuum cleaner without a battery device with respect to a direction from the top of the suction head to the suction material container. This results in a space-saving arrangement of the battery device on the suction head. It is advantageous if an actuating element for unlocking and / or locking the holding of a battery device on the battery holder is arranged on a handle and in particular bow handle, which is arranged on the suction head, or on a fastening region for the handle. This results in a simple operation for a user. Furthermore, the actuating element and optionally also a corresponding actuating device such as a lever or pivot lever can be arranged to save space.

In one embodiment, a post is provided as a mounting portion for the handle and on the post is a particular slidable or pivotable lever for locking / unlocking the battery device held and / or is guided on the post. This results in a mechanical structure with space-saving placement of the lever.

The aforementioned object is further achieved according to the invention in that a battery holder for a battery device comprises a movable protective device for electrical contacts on the suction head.

If the battery device is not used on the battery holder, then the protection device covers the electrical contacts on the suction head, so that they are protected in particular against mechanical intervention. The movable safety device can be positioned to save space on the suction head.

In particular, the protective device is designed so that when inserting a battery device to the battery holder, the protective device is moved so that the electrical contacts are released for the battery device. It can then be easily established a contact between corresponding mating contacts of the battery device and the electrical contacts on the suction head. In particular, the protective device comprises a sliding carriage with a protective area. The protection area covers the electrical contacts on the suction head when the battery device is not inserted. By inserting the battery device into the battery holder, the carriage can be move so that the electrical contacts are released and the mating contacts of the battery device can contact the electrical contacts of the suction head. In one embodiment, it is provided that a slide guide for the sliding carriage is fixed to a housing of the suction head and / or a motor console of the fan motor. This results in a simple structural design with optimized space utilization. It can be provided, in particular, that a stop for limiting a mobility of the carriage is arranged or formed on the housing. This results in a simple structural design with minimization of components. In particular, a protective position for the carriage can be defined in a simple manner, in which the protective area covers corresponding contacts on the protective head.

It is favorable if a displacement direction of the carriage

is parallel / antiparallel to a direction of insertion of the battery device to the battery holder. This results in a simple structural design with easy operation. It is easy to achieve automatic protection or automatic release of the protection.

It is favorable if a displacement direction of the carriage is at least approximately parallel to an axis of rotation of a blower motor of the blower device and / or at least approximately parallel to a rotation axis of a blower motor of the blower device and / or at least approximately parallel to a height direction of the suction material container and / or transversely and in particular perpendicular to a roller axis of one or more rollers over which the sucker is movably mounted on a base and / or at least approximately parallel to a steering axis of one or more steerable rollers over which the sucker is mobile mounted on a pad and / / or transversely and in particular perpendicular to a longitudinal direction of a Channel section of the at least one process air duct, wherein the channel section is disposed directly below the battery holder and / or the battery device to the suction head and the longitudinal direction corresponds to a main flow direction for a process air flow in the channel section and / or at least approximately parallel to a Aufsetzrichtung the suction head on the Suction tank is.

It is particularly advantageous if the movable carriage is supported by a spring device, wherein a spring force of the spring device must be overcome for a displacement of the carriage to release the electrical contacts. As a result, a release of the electrical contacts can be achieved in a simple manner when inserting the battery device. The force applied during insertion can overcome the spring force of the spring device.

The battery-operated vacuum cleaner according to the invention is designed in particular as a wet-dry vacuum cleaner.

An embodiment of a teat according to the invention, which is shown in FIGS. 1 to 9 and designated 10, comprises a suction container 12. The suction container 12 has a container bottom 14 (for example FIG. 6) on which a container wall 16 is arranged. The

Container wall 16 is for example integrally connected to the container bottom 14 and stands from this.

The suction container 12 has, for example, an at least approximately cylindrical shape.

The suction container 12 has an interior 18th

At the suction container 12, a suction port 20 is positioned with a suction pipe connection piece 22 (not shown in the drawings). In one embodiment, the nipple 10 comprises a movable plate 24. On the plate 24 rollers 26 are arranged. For example, three or four rollers 26 are provided. A respective roller 26 is rotatable about a roller axis 28.

It can be provided that the rollers 26 are pivotable about a respective steering axis 30. The steering axis 30 is oriented perpendicular to the roller axis of the respective roller 26.

The plate 24 has a receptacle 32 in the form of, for example, a recess for the suction material container 12. In this receptacle 32 of the suction container 12 is inserted fixed or detachable. The suction material container 12 and thus the vacuum cleaner 10 can be placed on the plate 24 with its rollers 26 mobile on a pad 34 (Figure 2).

A steerability of the rollers 26 allows a high ease of use with respect to "orientation" of the teat 10 in a suction operation.

The nipple 10 includes a suction head 36.

This suction head 36 is detachably fixed to the suction material container 12 via a fixing device 38.

In one embodiment, the fixing device 38 comprises tabs 40a, 40b (FIG. 6), which are in particular diametrically opposed, and which are movably positioned on the suction head 36. At the suction container 12 corresponding locking elements 42 are arranged, with which the respective tab 40a and 40b can be latched. The suction material container 12 extends in an elevation axis 44 in a height direction 46 (FIG. 7). If the nipple 10 properly rests on a flat surface 34, then the height direction 46 is perpendicular to this pad 34th

The height direction 46 is perpendicular to the respective roller axles 28 of the rollers 26 and parallel to the respective steering axles 30.

The suction head 36 can be placed on the suction material container 12 from above in an attachment direction 48 (cf. The Aufsetzrichtung 48 is anti-parallel to the height direction 46th

The suction head 36 has a support region 50, which is in particular annular. About this support region 50, the suction head 36 is supported on the suction material container 12 and in particular on a front region 52 of the

Suction tank 12 (wherein this end portion 52 faces away from the container bottom 14) from when the suction head 36 is fixed to the suction container 12. The suction head 36 has a housing 54 (hood 54).

In the housing 54, a blower 56 is arranged. The blower device 56 serves to generate a suction flow. The blower device 56 is held on the suction head 36 in one embodiment. When the suction head 36 is removed from the suction container 12, then the

Blower device 56 (with the suction head 36) from the suction container 12.

The blower device 56 includes a blower 58 and a blower motor 60. The blower motor 60 is an electric motor. It has a motor shaft 62 with a rotation axis 64. The rotation axis 64 is parallel to the height direction 46 or parallel to the attachment direction 48.

The motor shaft 62 is non-rotatably connected to one or more impellers 66 of the fan 58 of the fan 56. The blower motor 60 drives rotation of the impeller 66 about the axis of rotation 64.

The channel 63, in one embodiment, surrounds the fan motor 60 annularly and leads to an outlet on the housing 54.

As a result, a corresponding suction flow can be generated at the blower 58, via which a suction hose connected to the suction connection 20 can be pressurized with negative pressure. At the suction head 36, a filter device 68 is held. In one embodiment, the filter device 68 includes a filter basket 70. The filter basket 70 holds a filter 72.

It may be provided that the filter basket 70 is positioned on an underside of the suction container 12 (wherein at the suction container 12 fixed suction head 36 this underside faces the container bottom 14), that the filter basket 70 with the filter 72 at a fixed suction head 36th is immersed in the interior 18 of the suction container 12 (see, for example, Figure 6).

The filter device 68 serves to filter out dust particles and to prevent their access to the blower device 56.

The blower motor 60 is held on the suction head 36 via a motor bracket 61. On the motor console 61, one or more channels 63 are formed as cooling air passages for the blower motor. The filter body 70 is designed in particular removable, for example, to allow a wet operation of the teat 10.

At the suction head 36, a process air channel 74 is arranged or formed. The process air channel 74 establishes the fluid-effective connection between the blower device 56 on the suction head 36 and the interior 18 of the suction material container 12. It is an exhaust duct of the blower device 56. It establishes the connection to the ambient air. The suction head 36 has an upper side 76 (cf., for example, FIG. A height of the teat 10 (when the suction head 36 is fixed to the suction container 12) lies between the upper side 76 and the base 34, on which the teat 10 is placed. On the housing 54 of the suction head 36, a bow handle 78 is arranged (for example, Figure 2). This bow handle is designed so that the suction head 36 (and thus also the teat 10) can be grasped from above. The strap handle 78 defines a gap 80 through which a user's hand can dive through, so that the strap handle 78 is graspable.

An upper side 82 of the bow-shaped handle 78 defines the upper side 76 of the suction head 36 and thus of the nipple 10.

An envelope surface of the suction head 36 on the upper side 76 is, for example, a plane which is oriented transversely and in particular perpendicular to the height axis 44 of the suction material container 12.

The bow-shaped handle 78 has a web 84 which delimits the intermediate space 80 toward the upper side 82, and has a first post 86 and a second post 88, via which the web 84 is held on the housing 54. The first post 86 and the second post 88 are spaced apart from each other and each bound laterally the gap 80. The vacuum cleaner 10 is battery-powered and in particular supplied with electrical power via a rechargeable battery device 90. The battery device 90 is in particular a multi-cell battery pack or battery pack.

At the suction head 36, a battery holder 92 for holding the battery device 90 is arranged.

The housing 54 has towards the suction port 20 towards a wall 94 which is oriented obliquely to the height direction 46. This wall 94 is in particular at an acute angle 96 to the top 76th

(or an envelope level for the top 76). A typical value range for this acute angle 96 is in the range between 50 ° and 70 °.

The wall 94 may be flat or approximately flat or also have a curvature.

The second post 88 of the loop handle 78 abuts or lies adjacent to this wall 94. (The first post 86 is farther from the wall 94 than the second post 88.)

On the wall 54, a free area 98 is formed in the manner of a recess or recess. The free area 98 has a center plane 100, which is oriented parallel to the height axis 44 and also a center plane of the bow handle 78.

A corresponding cutout on the suction head 36, which is formed by the free area 98, has at least approximately the shape of a hollow cuboid. In one embodiment, a switch 102 is arranged laterally to the free area 98 on the wall 94. This switch 102 is in particular an on-off switch for the vacuum cleaner 10 (with respect to a suction operation). The suction port 20 is also located at the center plane 100; the center plane 100 is also a center plane for the suction port 20.

The clearance 98 is delimited downwardly in a direction 104 which faces (and is substantially parallel to and opposed to the height direction 46) from the top 76 to the suction container 12 by a bottom wall 106 (FIG. 9). The bottom wall 106 is oriented transversely to the height axis 44 and in particular perpendicular to this.

Laterally, the free area 98 is bounded by opposite side walls 108, 110, with the side walls 108, 110 spaced apart and projecting transversely from the bottom wall 106.

The side walls 108, 110 are oriented in particular parallel to the height direction 46.

Towards the rear, the free area 98 is bounded by a rear wall 112 (cf., for example, FIG. This rear wall 112 projects transversely from the bottom wall 106 and is oriented in particular perpendicular to it or the height axis 44. The rear wall 112 is connected to the side walls 108 and 110 and oriented transversely and in particular perpendicular to these.

Between the bottom wall 106, the side walls 108, 110 and the rear wall 112 of the aforementioned cuboid cavity is formed. At the free area 98, the battery holder 92 is arranged on the suction head 96. In one embodiment, it is partially and in particular completely arranged on the rear wall 112. The free area 98 is closed downwards (to the suction material container 12) through the bottom wall 106. To the rear, it is closed by the rear wall 112. Laterally it is closed by the side walls 108 and 110. At the top, towards the top 82, the open area 98 is open; the free area 98 is remote from the bottom wall 106 open. This allows the insertion of the battery device 90 to the battery holder 92 from above.

Furthermore, the free area 98 facing away from the rear wall 112 is open. As a result, for example, when inserting or removing the battery device 90 from the battery holder 92, the battery device 90 can be gripped. It has a grip area 113 (see FIG. If the battery device 90 is held on the battery holder 92, then this handle portion 113 is not or not completely immersed in the free area 98, but is accessible from the side. An operator can then grasp the battery device 90 on opposite gripping areas 113 with one hand and lead the battery device 90 upwards.

Through the open side of the free area 98 towards the front, the battery device 90 can be positioned accordingly. Furthermore, it is possible to read indications which are arranged on the battery device 90. The free area 98 forms a receiving area 118 at least for a partial area of the battery device 90.

The battery holder 92 has a guide device 114 for a counter guide device 116 of the battery device 90.

The guide device 114 is formed in particular on the rear wall 112. The guide device 114 includes, for example, one or more

Guide rails and the counter-guide device 116 includes one or more grooves, wherein a groove is adapted to a guide rail. It is also a kinematic reversal possible, in which case, for example, one or more grooves are arranged on the rear wall 112 and 90 corresponding guide rails are arranged on the battery device.

It is also possible that grooves and guide rails both on the

Battery holder 92 and are arranged on the battery device 90 corresponding to each other.

As described above, the battery device 90 can be inserted from above on the battery holder 92. An insertion direction 120 is in this case, in particular, parallel to the height axis 44 and, in particular, antiparallel to the height direction 46.

The insertion direction 120 is at least approximately parallel to the

Rotation axis 64 of the fan motor 60, that is parallel or deviates at most at a small acute angle, for example, at most 20 ° from the parallelism.

Furthermore, the insertion direction 120 is oriented transversely and in particular perpendicular to the roller axes 28 and thereby oriented at least approximately parallel to the steering axles 30.

It is further oriented at least approximately parallel to the mounting direction 48.

An execution direction 122 for the battery device 90 from the battery holder 92 (see FIG. 8) is antiparallel to the insertion direction 120. The battery holder 92 is associated with a locking device 124, via which a correctly positioned on the battery holder 92 battery device 90 is fixed to the suction head 36 in particular by locking. In one embodiment, the battery device 90 has one or more detent recesses 126. One or more levers 128 with (at least) one corresponding detent lug 130 are positioned on the suction head 36. A lever 128 is designed in particular as a pivot lever and pivotally mounted on a pivot bearing 129.

A corresponding lever 128 is spring-supported such that the lever 128 is acted upon by spring force so that when a latching recess 126 of a locking lug 130 is opposite, the latching lug 130 is automatically pressed into the latching recess 126.

To release such a locking connection, the corresponding spring force must be overcome. The lever 128 has an actuating element 132, on which a corresponding pressure can be exerted by an operator to cancel the latch, that is to overcome the spring force.

The lever 128 is in particular arranged pivotably on the second post 88 as a fastening region for the bow-shaped handle 78.

The actuating element 132 is in particular arranged so that it lies against an upper side 82 of the bow-shaped handle 78 and can thus be operated accordingly.

In one embodiment, the actuator 132 is part of the lever 138. If the battery device 90 is held on the battery holder 92, then this does not protrude above the top 96 of the suction head 36 and thus the

Sucker 10 out. A corresponding upper side 134 of the battery device 90 can be set back downwards relative to the upper side 76 of the suction head 36 (towards the suction-material container 12), or be flush with respect to a transition to the upper side 82 of the bow-shaped handle 78.

Furthermore, the battery device 90 does not protrude beyond an outer side 136 or an envelope for the outer side 136 (see FIG. In one embodiment, a movable guard 138 is provided for electrical contacts 140. The electrical contacts 140 are arranged on the suction head 36. An electrical connection of the battery device 90 is achieved when the electrical mating contacts just come into electrical contact with the electrical contacts 140 of the suction head 36.

If the battery device 90 is not inserted on the battery holder 92, then the movable protector 138 covers the electrical contacts 140 on the suction head 36.

In one embodiment, the movable guard 138 includes a movable carriage 142. This movable carriage 142 is slidable in a displacement direction that is parallel to the insertion direction 120 and the execution direction 122, respectively.

The carriage 142 is guided on a carriage guide 123. In one embodiment, this slide guide 143 is fixed to the motor console 61.

It can be provided that a housing part 145 of the housing 54 of the suction head 36 forms a stop for limiting the mobility of the carriage 142. Further housing parts can provide a seal, in particular from top to bottom (in the direction of the suction material container 12) between a recess for the lever 128 and the blower motor 60 in the housing 54. The movable carriage 142 is connected to the suction head 36 via a spring device 144 supported.

The spring means 144 tends to push the slidable carriage 142 away from the bottom wall 106.

When the battery device 90 is not inserted on the battery holder 92, the sliding carriage 142 is positioned by the spring device 144 such that a protective region 146 on the carriage 142 covers the electrical contacts 140.

This corresponding position is not shown in the drawings.

When the battery device 90 is inserted in the insertion direction 120, the insertion movement of the battery device 90 moves the displaceable carriage 142 in the insertion direction 120 counter to the spring force of the spring device 144.

As a result, the protective area 146 is moved along and the electrical contacts 140 are released. It can then just make an electrical contact of the battery device 90 with the electrical contacts 140.

When (after release of the lever 128) the battery device 90 is removed in the delivery direction 122, the movable carriage 142 moves under the action of the spring force of the spring device 144 in the outflow direction 122. The protection region 146 can then cover the electrical contacts 140 , For further details on the configuration of the corresponding battery holder 92, reference is made to the non-prepublished international application PCT / EP2016 / 074233 of October 10, 2016 by the same Applicant. This document is expressly incorporated by reference.

The battery device 90 extends in a longitudinal axis 148 (see FIG. The battery device 90 has an overall length L in this longitudinal axis 148. In particular, the battery device 90 has its largest dimensions in the longitudinal axis 148.

The longitudinal axis 148 is parallel to the insertion direction 120 or parallel to the axis of rotation 64 or parallel to the height axis 44. There is an overlap region of the battery device 90, if this is held on the battery holder 92, with the blower 56 before

(relative to a direction parallel to this longitudinal axis 148).

In Figure 8, a corresponding overlap region is indicated by the reference numeral 150.

In the direction of the longitudinal axis 148, this overlap region 150 lies with respect to the battery device 90, in particular at a length which amounts to at least 10% and preferably at least 20% and preferably at least 25% of the total length L of the battery device 90.

This results in a space-saving accommodation of the battery device 90 to the vacuum cleaner 10. The process air channel 74 has a channel section 152 (Figures 5, 8, 9), which is directly below the battery holder 92 and the battery device 90; a projection of the battery holder 92 and the battery device 90 along the height axis 44 meets this channel section 152.

This channel section 152 is designed (dimensioned) such that the inserted battery device 90 does not protrude beyond the upper side 96 of the suction head 36.

In one embodiment, the corresponding channel portion 152 has a first region 154 associated with the filter basket 70 and a second region 156 located higher above the height direction 46, which is closer to the blower motor 60.

The first region 154 has a height hi in the height direction 46. The second area has a height 156 h ₂ in the height direction 46.

An overall height is H = hi + h ₂ .

Preferably, the total height H is at most 70 mm and in particular at most 65 mm.

The channel section 152 directly below the battery device 90

or of the battery holder 92 is arranged next to a channel section 158 of the (cooling) channel 63 of the motor console 61. This channel section 158 (FIGS. 8, 9) of the channel 63 lies behind the rear wall 112.

The cooling air channel 63 and the process air channel 74 and thus also the channel sections 152 and 158 are not fluidly connected to each other. These are separated by (at least) one wall. At the transition from the channel section 152 to the channel section 158, a step 160 is formed. This step 160 corresponds to a cross-sectional enlargement of the process air channel 74 in comparison to the channel 63, wherein in particular the height in the height direction 46 increases at the step 160. The step 160 between the channel section 152 and the channel section 158 is formed over respective walls of the channel sections 152 and 158. The corresponding step area with the step 160 between the channel sections 152 and 158 is a counterpart to the free area 98, which is also a kind of step area.

Through the step 160 between the process air channel 74 and the channel 63 (for cooling air), the battery device 90 can be positioned on the suction head 96 to save space.

In principle, it is also possible that, alternatively or additionally, a step is formed on the cooling air channel 63 by appropriate design of this cooling air channel 63 in order to enable a corresponding positioning of the battery device 90 and in particular this battery device 90 closer to a center (to a central axis) of the suction head 36 position. The channel section 152 has a longitudinal extent in a direction transverse to the axis of rotation 64. A main flow direction of the process air in it lies transversely and in particular perpendicular to the axis of rotation 64.

The sucker according to the invention works as follows:

For a suction operation, the suction head 36 is fixed to the suction material container 12 via the fixing device 98.

At the suction port 20, a suction hose is connected.

The battery device 90 is inserted on the battery holder 92. The fan motor 60 is supplied via the battery device 90 with electrical energy and it is generated via the fan 58, a suction flow.

Suction material can be sucked into the interior 18 via this suction flow.

The formation of the process air channel 74 with its channel section 152 and the (cooling air) channel 63 with its channel section 158 and the step section 160 allows space-saving accommodation of the battery device 90.

In this case, the battery device 90 can be inserted from above into the insertion direction 120 on the battery holder 92 and removed upward in the direction of execution 122. This results in a space-saving accommodation on the suction head 36. This must not be increased in particular in its lateral dimensions.

About the lever 128 can be easily form a locking device 124. The second item 88 can be used to accommodate the lever 128.

Over the overlap area 150 can also achieve space-saving accommodation. By the insertion direction 120 from above or the execution direction 122 upwards, the battery holder 92 can be arranged with its guide device 114 to save space on the suction head 36.

The movable protective device 138 results in an optimized protection of the electrical contacts 140 when the battery device 90 is not used. Specifically, a center of gravity of a battery device 90 held on the battery holder 92 is positioned above a center of gravity of the nipple 10 (with no suction material picked up and with the battery device 90 removed). This results in an optimized arrangement with easy removability or usability.
