Inventive solution

The reference numbers in all claims have no limiting effect, but are only intended to improve their readability.

The solution of the problem is achieved by a hand-held battery-powered vacuum cleaner with the features of claim 1. The hand-held battery-powered vacuum cleaner has a suction through which sucked in the intended operation of the vacuum cleaner suction in an inflow direction in the vacuum cleaner, a electric accumulator for operating the motor of a motor-blower unit of the vacuum cleaner and a connector for charging the electric accumulator. The connector has an intended mating direction along an axis which extends parallel to the inflow direction or with this an angle of less than 45 °, preferably less than 22 °, includes, and is arranged accessible via the bottom side of the vacuum cleaner to the vacuum cleaner.

In the present case, angular dimensions are based on a semicircular segment of 180 °, that is to say that two directions can enclose an angle of at most 180 °, in which case they would point straight in the opposite direction.

For the purposes of the present invention, a "hand-held vacuum cleaner" is a vacuum cleaner that is designed not only for use with a suction tube or suction hose connecting a suction air inlet of the vacuum cleaner to a floor cleaning floor nozzle, but also or even designed exclusively for use without such a suction tube or such a suction hose, for example, to clean furniture. However, in the context of the present invention, the group of hand vacuum cleaners also includes vacuum cleaners which, in addition to the abovementioned possibilities, can also be operated with a suction pipe or a suction hose and a floor nozzle which can be connected to the suction pipe or the suction hose for cleaning a floor. When using a suction tube, the user moves the hand-held vacuum cleaner with the attached suction pipe and the attached floor nozzle on the floor to be cleaned area.

The hand-held vacuum cleaner, due to its compact dimensions and light weight, is capable of being comfortably held and carried in the hand, preferably with one hand only. Particularly preferably, the weight is less than 2 kg, more preferably less than 1.5 kg, each without an accumulator. Its preferred length from the handle to the air inlet without attached suction hose or suction tube is less than 60 cm, more preferably less than 50 cm.

"Battery operated" should be understood that the vacuum cleaner is equipped with an electric accumulator, with which the vacuum cleaner can be operated without further power supply. This does not exclude that the vacuum cleaner can be operated additionally or alternatively via a power supply line, such as when the accumulator is exhausted, or during charging of the accumulator. With the accumulator operation is advantageously achieved that the freedom of movement of the vacuum cleaner is no longer limited by a cable for the power supply of the vacuum cleaner. The preferred hand-held battery operated vacuum cleaner is a "regular size battery-operated vacuum cleaner" according to the February 2017 draft of DIN EN 62885-4.

Hand-held battery-operated vacuum cleaners are becoming increasingly popular because they are easy to handle and are therefore ideal for sucking in small amounts of dirt. Like conventional mains-powered vacuum cleaners, such hand-held vacuum cleaners have a motor-blower unit for generating the suction air flow, wherein the suction air from a suction port, for example a suction via a Staubabscheidevorrichtung to the motor-blower unit and then, for example, to a blow-out Outlets is guided. The Staubabscheidevorrichtung is formed in hand-held vacuum cleaners usually as bagless Staubabscheidevorrichtung in which the incoming air is rotated to separate dust and dirt on the principle of centrifugal separator.

For the purposes of the present invention, the "intended direction of insertion" is the direction in which the connector or mating connector would have to be performed with a fixed corresponding mating connector or connector in the direction of this corresponding mating connector or connector to establish a current-conducting contact between the connector and the mating connector , The plug-in directions of the plug connector and mating plug connector thus point in the manufacture of a current-conducting contact to the corresponding mating plug connector or connector.

In the following, terms such as "top", "top", "bottom" and "bottom side" will be used to describe the hand-held vacuum cleaner and the charging station. These are to be understood in terms of the present invention in terms of the direction of gravity in the intended use of the vacuum cleaner and the charging station. The "bottom side" of the vacuum cleaner is the side of the vacuum cleaner whose surface normal in the intended operation of the vacuum cleaner generally downward and also facing downward front of the user to the user. The front side is the side of the vacuum cleaner, the surface normal is generally oriented counter to the direction of inflow of the suction air into the suction and at the usually the suction nozzle is arranged. The front faces away from the user when using the vacuum cleaner with the front facing down. Dir back of the vacuum cleaner is the side whose surface normal is generally oriented in the inflow of the suction air into the suction nozzle. The "top" of the vacuum cleaner is the side of the vacuum cleaner, the surface normal in the intended operation of the vacuum cleaner generally facing upwards and facing away from the front of the user away. A handle for guiding the vacuum cleaner is usually arranged in the region of the back and / or top.

The fact that the connector is arranged accessible via the bottom side of the vacuum cleaner to the vacuum cleaner, it is easily accessible for a charging station, to which the vacuum cleaner coupled with its bottom side. As a result, the charging station, as shown below, have a particularly simple construction. This also makes a particularly simple handling of the system of vacuum cleaner and charging station possible. In addition, the bottom access to the connector aesthetic be advantageous because it can be avoided that the connector is visible from above or from one side when looking at the vacuum cleaner. This aspect of the invention takes advantage of the fact that the vacuum cleaner in normal use is usually viewed only from above or from the side.

Charging stations for hand-held battery-powered vacuum cleaners are often designed for wall mounting, with the vacuum cleaner inserted into the cradle with the suction nozzle facing down. As a result of this orientation of the vacuum cleaner, a suction nozzle attached to the vacuum cleaner or a suction pipe attached to the vacuum cleaner can advantageously likewise point downwards, generally hanging downwards. This allows a stable storage of the vacuum cleaner with attached suction nozzle or attached suction pipe. In addition, this orientation of the vacuum cleaner allows a particularly hygienic handling, because when the vacuum cleaner sits at gripping height in the charging station, suction nozzle and pipe, which are often dirty, hang below this gripping height. Characterized in that the connector has an intended insertion direction along an axis which extends parallel to the inflow direction or with an angle of less than 45 °, preferably less than 22 °, includes, when the vacuum cleaner from above or from below in the charging station is used, at the same time the connector to be connected to a mating connector of the charging station to make an electrically conductive contact between the connector and the mating connector. This allows a particularly simple construction of the charging station and a particularly simple handling of the system of vacuum cleaner and charging station.

The invention also provides a hand-held battery-operated vacuum cleaner with the features of claim 2 is achieved. The hand-held battery-powered vacuum cleaner has a suction nozzle, is sucked through the intended operation of the vacuum cleaner suction in an inflow direction in the vacuum cleaner, an electric accumulator for operating the motor of a motor-blower unit of the vacuum cleaner and a connector for charging the electric Accumulator. The connector has an intended insertion direction and arranged and arranged on the vacuum cleaner, that the intended plugging direction of the connector runs counter to the inflow direction or with this an angle of more than 135 °, preferably of more than 168 °, includes. By This plugging direction, it is particularly well suited for use with a charging station with the invention, in which the vacuum cleaner is used from above. Because in such a case can be connected simultaneously with the insertion of the connector with a mating connector of the charging station to make a current-conducting contact between the connector and the mating connector. This allows a particularly simple construction of the charging station and a particularly simple handling of the system of vacuum cleaner and charging station.

Accordingly, the invention is also achieved by a system comprising a hand-held battery operated vacuum cleaner as described above and a charging station for this vacuum cleaner, wherein the vacuum cleaner and the charging station are formed so that the vacuum cleaner can be inserted into the charging station in a manner , in which the connector of the vacuum cleaner and the mating connector of the charging station are electrically connected.

Detailed description of embodiments of the invention

In the following description of preferred embodiments of the present invention, like reference characters designate like or similar components.

In the FIGS. 1a and 1b the vacuum cleaner 1 according to the invention is shown from the outside. The vacuum cleaner 1 has a handle 2 to be held in the hand can. In addition, a removable electric battery pack 3 is provided (shown in the figures only without the actual battery elements), which supplies a blower motor (not shown in the figures) of a motor-blower unit 4 of the vacuum cleaner with electricity. The accumulator 3 of the vacuum cleaner 1 is formed replaceable and can be inserted in a direction of insertion from behind obliquely forward and downwards in a designated receptacle of the vacuum cleaner 1. In the reverse direction, a held in the recording accumulator 3 in a removal direction are removed from the recording, wherein the removal direction is directed opposite to the insertion direction. About a gun switch 5, the blower motor can be switched on and off. With a boost or turbo button 6, the fan motor can be operated temporarily with a particularly high speed. Below the motor-blower unit 4 is a blow-out opening 7 for the emerging from the motor-blower unit 4 suction air.

In addition, the vacuum cleaner on a general upright centrifugal separator 8. This centrifugal separator 8 is arranged substantially parallel to the likewise upright motor-fan unit 4. At the centrifugal separator 8, in the upper region, a suction nozzle 9 is provided with the suction air can be fed into the centrifugal separator 8. The suction nozzle 9 is substantially tubular, wherein the longitudinal axis of the tube is perpendicular to the longitudinal axis of the centrifugal separator 8. At the end of the suction nozzle 9 facing away from the centrifugal separator 8, different suction nozzles 10 (in FIG FIGS. 4 and 5 shown) or a suction tube 11 (also in FIGS. 4 and 5 shown). As in FIG. 2 recognizable, the upper part of the centrifugal separator 9 serves as a separator. When the fan motor suction air is sucked through the suction port 9 in an inflow to the centrifugal 8 and down in the centrifugal separator 8 down, the dust centrifugal force dirt and liquids can be deposited, which follows the gravity in the lower part of the centrifugal separator 8, which serves as a dust collector. The already partially freed of dust in this way air now passes through a filter 12, which further dust and other components can be removed from the air. As a rule, these components of gravity also fall from the filter 12 into the dust collector. Through the filter 12, the air enters the motor-fan unit 4 of the vacuum cleaner 1 and is blown through the exhaust port 7 vacuum cleaner 1.

Like also in FIG. 2 as in FIG. 13 recognizable, the vacuum cleaner 1 has on its bottom surface a pocket in the form of a forwardly open but closed to the rear T-groove 13. The closed end of the T-slot 13 forms a stop 14, in which there is an opening 15, through which a arranged in the interior of the vacuum cleaner 1 connector in the form of a female connector socket 16 is accessible. The Hollow socket 16 is good in the FIGS. 15 and 16 recognizable. The plug-in direction of the hollow socket 16 is slightly inclined opposite to the inflow, is sucked into the suction air in the vacuum cleaner 1. The undercuts of the T-groove 13 form blocking surfaces, which, as in FIG. 13 recognizable, at the open end of the T-slot with insertion bevels 17 are equipped.

The charging station 18 is provided with a in FIG. 12 well-recognizable T-shaped carriage 19 equipped with which the charging station 18 engages in the T-slot 13. The carriage 19 is also equipped with insertion bevels 20 on its upper side, with which it enters the T-slot 13. When inserted into the charging station 18 vacuum cleaner 1, the inner surfaces of the T-bar of the carriage 19 engage behind the locking surfaces of the T-slot 13. The front of the carriage 19 abuts when inserted into the charging station 18 vacuum cleaner 1 to the stop 14 of the T-slot 13 of the vacuum cleaner 1 on. At the front of the carriage 19, a mating connector of the charging station 18 is also arranged, which is designed as a hollow connector 21 and the insertion direction facing upward. When inserted into the charging station 18 vacuum cleaner 1, the hollow plug 21 is inserted through the opening 15 in the stop 14 in the hollow socket 16. This is in FIGS. 6 . 14 . 15 and 16 shown.

The charging station 18 is mountable to a wall, to which it is equipped with mounting holes 22, of which in FIG. 15 one is shown. It also has an in FIG. 12 well recognizable shell 23, which, as in FIGS. 6 and 9 represented, the lower part of the centrifugal separator 8 can accommodate. On its underside, the charging station 18 is equipped with downwardly open cylinder sections, to which, as in the FIGS. 4 and 5 shown, suction nozzles 10, suction tubes 11 and other accessories for storage from below are plugged. In an embodiment, not shown in the figures, the charging station 18 also has a separate from the receptacle for the vacuum cleaner recording for a battery. This recording for the accumulator is equipped with a counter charge port for a charging port of the battery, so that the accumulator regardless of the vacuum cleaner 1, z. B. when it has been removed from the charging station for use vacuum cleaner 1, can be charged. This recording can be provided, for example, at the upper end of the charging station 18 at the same height of the point to he the accumulator 3 of the vacuum cleaner 1 when inserted into the charging station 18 vacuum cleaner 1.

The sectional drawings 6, 7 and 8 and the corresponding perspective views 9, 10 and 11 show how the vacuum cleaner 1 is removed upwards from the loading station 18 or vice versa is inserted from above into the loading station 18. When removing the vacuum cleaner 1 from the charging station 18, the carriage 19 of the charging station 18 slides out of the T-slot. In the same way, the hollow connector 21 slides out of the female connector socket 18 until charging station 18 and vacuum cleaner 1 and hollow connector socket 16 and hollow connector 21 are separated from each other. When inserting the vacuum cleaner 1 from above into the charging station 1, the T-slot 13 slides over the carriage 19, which is facilitated by the insertion bevels 20. T-slot 13 and carriage 19 align the vacuum cleaner 1 relative to the charging station 18 so that the female connector socket 16 can slide over the hollow connector 21 and so creates a secure electrical connection. The system according to the invention is simple in construction and handling; in particular, a convenient recharging of the vacuum cleaner is made possible.

The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various embodiments.
