Definitions

  • the invention relates to a vacuum cleaner with a sound-absorbing body which can be plugged onto the motor of the blower unit and which surrounds the motor housing while leaving a flow space.
  • Such a vacuum cleaner is known from DE-GM 75 14 249.
  • a tubular body made of foam is pushed over the motor of the blower unit.
  • the air flow exiting on the free end face of the motor is deflected towards the blower of the blower unit by means of a dimensionally stable deflection cap, which is placed on the motor housing, and flows between the outside of the deflection cap and the foam body to the rear of the vacuum cleaner provided with exit slots.
  • Both the deflection cap and the tubular foam body take up a lot of space, so that there is a correspondingly high need for storage space for stockpiling during production.
  • the invention has for its object to provide a vacuum cleaner of the type described in such a way that less storage space is required for the storage of the parts required for noise reduction on the vacuum cleaner.
  • the sound-absorbing body is plate-shaped and is provided with a hat-shaped deformation, wedge-shaped incisions which extend from the peripheral edge with its tip to the center of the body. Since the plate-shaped soundproofing body is only brought into its corresponding spatial shape when installed in the vacuum cleaner, results only a correspondingly small space requirement due to the plate-shaped design.
  • the hat-shaped deformation of the sound-absorbing body is achieved by means of a cap which engages over the sound-absorbing body placed on the free end face of the motor. Such a cap is pushed over the sound-absorbing body and bends the tabs formed by the incisions parallel to the motor housing, so that the sound-insulating body envelops the motor housing.
  • a simplification of production results from the fact that the cap is molded onto the vacuum cleaner housing. As a result, the deformation of the plate-shaped body takes place automatically when the corresponding vacuum cleaner housing part is put on.
  • the assembly of the sound-absorbing body is facilitated by the fact that it is provided with at least one push-fit opening that fits onto a projection provided on the free end face of the motor.
  • a blower unit arranged in the blower chamber 3 consists of a motor 4 and a blower 5 connected to it.
  • a plate-shaped, sound-absorbing body 7 on the free front side of the motor 4 hung up.
  • a molded on the upper half of the vacuum cleaner housing 8 engages over the sound-absorbing body 7 and deforms it into a hat enclosing the motor housing.
  • the cap 8 is dimensioned such that the sound-absorbing body 7 does not abut the motor housing, but a passage gap 9 remains for the air flow.
  • the sound-absorbing body 7 is plate-shaped and provided with wedge-shaped incisions 10. These incisions 10 allow the sound-absorbing body 7 to be deformed into a hat.
  • the sound-absorbing body 7 is formed into a hat, for example by overlapping connection of the side edges of the incisions 10, which can be placed on the motor 4. The deformation to a hat is done in a separate operation.
  • the corresponding deformation of the sound-absorbing body 7 can also take place by fitting a cap 8 over the sound-absorbing body 7 placed in a plate shape on the free end face of the motor 4.
  • a cap 8 In order to prevent the body 7 placed on the end face of the motor 4 from slipping, it has a push-on opening 11, by means of which it fits onto a corresponding projection 12, e.g. a bearing cap of the motor 4 can be plugged on.
  • the cap 8 is provided on the vacuum cleaner housing, then the deformation of the sound-absorbing body 7 takes place with the Put on the corresponding housing half of the vacuum cleaner. No separate work step is therefore necessary.
