Definitions

• the invention relates to a hand-held working device, in particular a vacuum cleaner, with an electric drive motor and a power supply device according to the preamble of claim 1.
• Power supply device for an electrical consumer described which is a vacuum cleaner, wherein the power supply device is designed as an external unit, which is formed independently of the electrical load.
• the power supply device consists of a housing in which a battery pack (battery pack) is interchangeable added.
• the housing of the power supply device includes a socket, via which the electrical load is to be connected.
• the power supply of the electrical load via the provided by the battery pack electrical energy, which is provided to adapt to various required voltage values of the consumer control electronics.
• the invention is based on the object with simple constructive measures, a hand-held implement, which is equipped with an electric drive motor to the effect that "even a network-independent operation of the
• the implement should also be used for the power supply of other tools.
• the hand-held implement has an electric drive motor and a power supply device which serves to supply power to the drive motor.
• the power supply device comprises a power plug for connection to an external power source, in particular to mains power, as well as a detachably connected battery pack (battery pack), wherein the power supply of the electrical
• Integrated circuit This allows in principle a network-independent operation of the hand-held implement, for example, in situations where the length of the power plug cable is not sufficient or an external power source is not available.
• Another advantage is the ability to operate at a connection of the implement to the external power source via the power plug not only the electric drive motor, but also to recharge the battery pack.
• Battery pack and power plug are for this purpose advantageously in a common, internal circuit through which the electric drive motor of the implement is supplied with electrical energy.
• the battery pack is in this case connected in particular parallel to the internal electrical lines, via which the drive motor is supplied with electrical energy.
• the charging of the battery pack can be carried out independently of the operation of the electric drive motor, ie both when the drive motor and switched off.
• the battery pack is designed in particular interchangeable and can be used in a battery pack receptacle, which is part of the power supply device. If the battery pack is currently not required for the operation of the hand-held implement, it can also be removed and used for an external, further implement. The operation of the hand-held
• Working device is possible when connecting the power plug to the external power source even when the battery pack is not inserted.
• the implement is advantageously provided with at least one outlet, which is connected to the
• Power supply device is connected in the implement and in turn is used to connect an external consumer.
• the implement can serve as an extension cable or as a multiple plug.
• the electric drive motor in the hand-held implement is designed as a DC motor to allow operation of the motor with the usually present as a DC current of the battery pack.
• the electric drive motor in the hand-held implement is designed as a DC motor to allow operation of the motor with the usually present as a DC current of the battery pack.
• the power supply device is a transformer including smoothing and rectification circuit integrated, which is used to generate direct current from the AC power of the external power grid.
• Transformer is arranged in particular between the device-side power plug and the drive motor, the device-side socket for connecting an additional implement is advantageously placed on the high-current side of the transformer.
• the device-side socket for connecting an additional implement is advantageously placed on the high-current side of the transformer.
• a transformer and a switching power supply can be used instead of a transformer and a switching power supply.
• the hand-held implement is designed as a vacuum cleaner 1, which has a suction hose 3 on a housing 2, in which a fan 4 for generating an air flow, an electric motor 5 for driving the fan 4, a filter 6 and a generally designated 7 power supply is added ,
• the power supply device 7 includes power lines 8 and 9, which form an internal circuit for powering the electric motor 5.
• the electric motor 5 is advantageously designed as a DC motor, which can be operated at low voltage.
• a power cable 10 is connected to a power plug 11, which is provided for connection to an external power source, in particular to the mains.
• a transformer 13 to transform the high voltage from the external power to the required low voltage.
• the current drawn from the network is also smoothed and transformed from AC voltage to DC voltage.
• a socket 12 is connected to the power lines 18 and 19, which is accessible from the outside in the housing 2 of the vacuum cleaner 1. To the socket 12, an additional electrical load can be connected.
• a battery pack 14 is provided, which is part of the power supply device 2 and interchangeable inserted into a battery pack receptacle 15, which is connected in parallel to the power lines 8 and 9.
• a battery pack receptacle 15 which is connected in parallel to the power lines 8 and 9.
• Power supply device 2 is connected via the power plug 11 to this power source, the operation of the electric motor 5 via this external power source; at the same time the battery pack 14 can be charged.
• the external power source and an operation of an additional electrical load by plugging into the socket 12 on the housing 2 is possible.
• the battery pack receptacle 15 is generally designed as an interface that is suitable for receiving various battery pack geometries, for example, for battery packs that are designed as a block pack or as an O-pack. Furthermore, the battery pack used can be charged or discharged by means of control electronics with different voltage levels.
