Definitions

  • the invention relates to a vacuum cleaner in small format according to the preamble of claim 1.
  • the purpose of the invention is to provide an easily transportable and easy-to-handle vacuum cleaner with which objects can be cleaned by suction, such as e.g. upholstery, curtains, car interiors, carpets and the like.
  • a pair of brushes 21 lies on a swivel radius outside a vertical axis 25 of the device, which means that when the brushes 21 are placed on a base, the device constantly runs away or rotates, as a result of which fatigue-free work is not guaranteed.
  • the known hand-held cleaning device is further disadvantageous in its structural design, and it has only a relatively low suction power.
  • the present invention has set itself the task of developing a vacuum cleaner of the type mentioned in such a way that a high suction power is achieved with a small space requirement and that fatigue-free working is ensured.
  • the invention is characterized by the features of the characterizing part of patent claim 1.
  • the motor and transmission as well as the suction turbine and dust bag are arranged in a single housing, the housing being approximately elongated and rectangular in cross section, so that a compact structure results.
  • the brushes are designed as rotating, roller-shaped brushes and several brushes always work in pairs so that a pair of brushes is driven in opposite directions and between them the suction opening for sucking up the dirt.
  • All suction openings are connected to the dust bag via a common channel, the dust bag itself being arranged in the housing and being held there in an easily replaceable manner by an associated flap in the housing.
  • the dust bag is arranged outside the housing.
  • the dust bag can be inserted into the housing as an exchangeable cassette.
  • a suction indicator can be attached in the housing, which indicates the filling level of the dust bag.
  • a suction indicator can be attached in the housing, which indicates the filling level of the dust bag.
  • the counter-rotating brushes not only consist of a bristle material, but the brushes can also consist of wire bristles, so that it is possible with the handheld vacuum cleaner to dedust, remove rust, polish and remove paint.
  • the handheld vacuum cleaner provides a motor with a drive power of around 100 watts, which is driven by 220 volts, which achieves excellent suction power.
  • This motor and the suction turbine driven by it preferably have a number of revolutions of 15,000 revolutions per minute, and the reduction gear assigned to the motor works in a ratio of 1: 2 on the output shaft for driving the brushes, so that the output shaft rotates with about 7500 revolutions.
  • Pinions are arranged on the output shaft in a rotationally fixed manner, counter-rotating pinions being provided one behind the other, so that the roller-shaped brushes lying in one plane are driven in opposite directions.
  • the pinions work on gears, which in turn are connected to the brush rollers in a rotationally fixed manner and a reduction ratio of 1:20 is again achieved here, so that in a preferred exemplary embodiment the brushes rotate at a speed of approximately 375 revolutions per minute.
  • the handheld vacuum cleaner consists of a housing 1, which has a beveled cover surface 2 at the front, so that the handheld vacuum cleaner can also be easily moved under low objects.
  • the housing encloses a receiving space 3 for a motor 4, which is rotatably connected with its drive shaft 5 to a first gear 6, which works on a second gear 7, which is mounted on the one hand in a bearing plate 8 on the motor and on the other hand in a flange 9 of the Reduction gear.
  • This gear 7 is connected in a rotationally fixed manner to a shaft 10, which in turn is connected in a rotationally fixed manner to the turbine wheel 11, which is arranged in a further receiving space 12.
  • the receiving space is delimited by a rear wall 13, in which an opening 14 is arranged, while the receiving space 12 is defined at the front by a closed wall 15.
  • the wall 15 forms the rear wall of a front terminal space 16, which is used for the cable entry of the mains cable and for attaching the strain relief.
  • the receiving space 3 is delimited in the direction of the dust bag 21 by a rear wall 22, in which a plurality of openings 23 are arranged for the air to flow through.
  • This wall 22 serves as a safety when the dust bag 21 is removed so that the user cannot reach into the motor from the side of the chamber 24 in which the dust bag is arranged.
  • the dust bag itself is interchangeably arranged in the chamber 24 in a manner not shown in detail and takes up the dirt via the suction nozzles 25.
  • suction nozzles 25 lie in parallel on a channel 26 and the channel 26 is in turn connected to the chamber 24 in an air-tight manner.
  • the suction nozzles 25 are profiled approximately triangular in cross-section and have a front split suction slot 27. After the brushes 32, 33 are present in pairs and have a mutual spacing in the middle, a suction slot 27 is assigned to each brush 32, 33.
  • the opposing drive of the brush pairs 32, 33 is now carried out as follows:
  • this gear 7 meshes with a gear 28 which is connected in a rotationally fixed manner to an output shaft 29.
  • the output shaft 29 is rotatably mounted in a bearing plate 37 on the rear of the housing 1 and in a front bearing plate 38 on the front of the housing 1.
  • the output shaft 29 is rotatably connected to a gear 30, the gear 30 in turn meshing with a pinion 31, which is rotatably connected to a shaft 39, which shaft 39 is rotatably connected to the brushes 32,33.
  • suction slot 27 is arranged between two pairs of brushes 32, 33 driven in opposite directions.
  • FIG. 3 shows the housing again in the front view and the channel 26 is shown in broken lines, which is connected in an air-tight manner to the divided suction slot 27, wherein one suction opening 40, 41 is assigned to one suction slot 27.
  • FIG. 4 shows again schematically how the suction slots 27 are connected to the channel 26 in an air-tight manner and the channel in turn opens into the dust bag 21 with a front mouth 42, so that the air is deflected in the direction of arrow 43 at the mouth.
  • the entire mechanism is mounted in the area of a base plate 36, which forms the underside of the housing 1, additional bearing points 44 being arranged in the area of the base plate 36 for the output shaft 29.
  • this housing shell 45 The purpose of this housing shell 45 is to hold and cover the pinions 31 for driving the pairs of brushes 32, 33. If the housing shell 45 is removed, the brush pairs 32, 33 fall down with the shaft 39 and can thus be exchanged easily.
  • the chamber 24 is connected to the dust bag 21 with a corresponding filling indicator.
  • each pair of brushes 32, 33 carries the dirt lying on the surface to be cleaned directly to the suction slot 27, so that an excellent cleaning effect is provided.
