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, the group of hand vacuum cleaners in the context of the present invention also includes those vacuum cleaners which, in addition to the aforementioned possibilities with a suction pipe or a suction hose and a connectable to the suction pipe or suction hose floor nozzle for cleaning a floor can be operated. 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.

In a preferred hand-held vacuum cleaner are in intended operation with suction or suction hose and connectable to the suction pipe or the suction hose nozzle motor, blower and Staubabscheidevorrichtung in the upper half, particularly preferably in the upper third of the distance from the floor nozzle to a handle arranged the vacuum cleaner.

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-powered vacuum cleaner is a "regular size battery-operated vacuum cleaner" designed in February 2017 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 an engine-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 blowout with 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-side access to the connector can be aesthetically advantageous because it can be avoided that the connector at view on the suction device from above or from one side is visible. 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-operated 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.

The accumulator package 3 of the vacuum cleaner 1 is changeable and can in a direction of insertion from behind obliquely forward and down in a designated receptacle of the vacuum cleaner 1 be inserted. In the opposite direction, an accumulator held in the receptacle 3 be removed in a removal direction from the recording, the removal direction is directed opposite to the insertion direction. Above 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 there is a blow-out opening 7 for the out of the motor-blower unit 4 emerging suction air.

In addition, the vacuum cleaner has a general upright centrifugal separator 8th on. This centrifugal separator 8th is substantially parallel to the also upright motor-fan unit 4 arranged. At the centrifugal separator 8th , in its upper part, is a suction nozzle 9 provided with the suction air in the centrifugal separator 8th can be recovered. The suction nozzle 9 is substantially tubular, wherein the longitudinal axis of the tube perpendicular to the longitudinal axis of the centrifugal separator 8th runs. Am from the centrifugal separator 8th opposite end of the suction 9 can use different suction nozzles 10 (in 4 and 5 shown) or a suction tube 11 (also in 4 and 5 shown). As in 2 recognizable, serves the upper part of the centrifugal separator 9 as a separator. When the blower motor is switched on, suction air is sucked through the suction port 9 in an inflow direction to the centrifugal separator 8th sucked in and circling in the centrifugal separator 8th down, whereby by the centrifugal dust dirt and liquids can be separated, which following the gravity in the lower part of the centrifugal separator 8th falls, which serves as a dust collector. The already partially dust-free air in this way now passes through a filter 12 , whereby further dust and other components from the air can be removed. As a rule, these components also fall by gravity from the filter 12 into the dust collector. Through the filter 12 the air enters the motor-blower unit 4 of the vacuum cleaner 1 and gets through the exhaust opening 7 vacuum cleaner 1 blown out.

Like also in 2 as in 13 recognizable, points the vacuum cleaner 1 on its bottom surface a pocket in the form of a forwardly open but closed back T-slot 13 on. The closed end of the T-slot 13 makes a stop 14 in which there is an opening 15 located by the one inside the vacuum cleaner 1 arranged connector in the form of a hollow jack 16 is accessible. The hollow plug socket 16 is good in the 15 and 16 recognizable.

At the front of the carriage 19 is also a mating connector of the charging station 18 arranged as a hollow connector 21 is executed and the plug direction facing upward. In the charging station 18 inserted vacuum cleaner 1 is the hollow connector 21 through the opening 15 in the stop14 into the hollow plug socket 16 plugged in. This is in 6 . 14 . 15 and 16 shown.

The charging station 18 is mountable on a wall, to which they have mounting holes 22 is equipped, of which in 15 one is shown. It also has an in 12 well recognizable shell 23 on that, as in 6 and 9 shown, the lower part of the centrifugal separator 8th can record. On your bottom is the charging station 18 equipped with downwardly open cylinder sections, to which, as in the 4 and 5 shown, suction nozzles 10 , Suction pipes 11 and other accessories for storage from below are attachable. In an embodiment not shown in the figures, the charging station 18 In addition, a separate from the receptacle for the vacuum cleaner recording for a battery. This accumulator accumulator is equipped with a counter charge port for charging the accumulator so that the accumulator is independent of the vacuum cleaner 1 , z. B. when he vacuum cleaner 1 has been removed for use from the charging station, can be charged. This shot may be, for example, at the top of the charging station 18 at the same height of the place, to him the accumulator 3 of the vacuum cleaner 1 in the charging station 18 inserted vacuum cleaner 1 be provided.

The sectional drawings 6 . 7 and 8th and the corresponding perspective representations 9 . 10 and 11 show how the vacuum cleaner 1 up from the charging station 18 taken or vice versa from above into the charging station 18 is used. When removing the vacuum cleaner 1 from the charging station 18 the sled glides 19 the charging station 18 out of the T-slot. In the same way, the hollow connector slides 21 from the hollow socket 18 out, until charging station 18 and vacuum cleaners 1 as well as hollow socket 16 and hollow connector 21 are separated from each other. When inserting the vacuum cleaner 1 from the top into the charging station 1 slides the T-slot 13 over the sledge 19 what caused by the insertion bevels 17 . 20 is relieved. T-slot 13 and sledges 19 set up the vacuum cleaner 1 opposite the charging station 18 so out that the hollow jack 16 over the hollow connector 21 can slide 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.
