Definitions

  • the invention relates to a vacuum cleaner with an electric motor, which is fastened between a lower support plate and an upper clamping plate, further with electrical or electronic components fastened to circuit boards in the flow-through housing and with an intake duct and an exhaust air duct for the engine cooling air.
  • EP-A-99 466 a vacuum cleaner with a multiple winding outlet path and a sound-absorbing lining in this outlet path is known.
  • the disadvantage of this construction is that the circuit board is not cooled.
  • the cross-sectional changes in the intake duct lead to high flow losses.
  • the proposed lining causes additional material and assembly costs.
  • the object of the invention is to develop a vacuum cleaner of the known type so that a substantially increased service life of the electrical and electronic components is achieved, which should be arranged in a housing in a space-saving and easily replaceable manner.
  • the intake duct for the engine cooling air runs essentially U-shaped and is thus divided into three sections and the boards with their components are arranged in the intake duct and are at least partially coated, with different gaps forming. It is also essential that an asynchronous motor is not used, but a commutatorless DC motor - as proposed in DE-U-8 704 717 - which only requires relatively small electronics.
  • circuit boards with their components can thus be accommodated in the first leg, in the horizontal section and / or in the second leg, and the engine cooling air flows through them directly and cools them well. They can also be easily replaced, as will be explained in more detail below.
  • the use of the commutatorless DC motor has the advantage that a much smaller electric motor can be used, which has a different vibration ratio due to its lower weight and requires power control with boards that are significantly smaller than the conventional boards for the power control of asynchronous motors. Together, these features result in the possibility of arranging the circuit boards directly in the engine cooling air, which results in the desired substantial extension of the service life of these components.
  • the parts are also easy to replace.
  • the intake duct is placed with its one nozzle (first leg) on the already existing intake opening for the suction of the cooling air for the engine onto the motor clamping plate and with the other nozzle (second leg) it is directly connected to the stator of the with the interposition of a sealing ring Motor attached and connected to it in an air-tight manner.
  • control electronics are fully located in the cooling air flow for the engine, upstream of the engine.
  • this also ensures that vacuum cleaners which have been in operation so far can be retrofitted with such a unit.
  • the existing AC motor simply has to be replaced by the novel commutatorless DC motor, and the flow housing with the electronics integrated therein is then simply placed on the already existing motor chuck.
  • Each motor is then connected to such a flow housing, with the control of each motor being implemented separately via the circuit electronics arranged in the respective flow housing.
  • the motor-side socket of the housing with the electronics integrated on it is air-tight with the upper part, i.e. So is connected to the fixed winding part of the motor and that an outlet cross-section is still formed around the motor in the clamping plate, so that this ensures that the cooling air is guided inward into the motor through the flow housing, flows through the motor to the Flows past windings, is deflected by approx. 180 ° and flows out in the opposite direction to the incoming cooling air on the outside of the flow-through housing, appropriate sound insulation mats being arranged here in the outflow channel formed by the clamping plate and hood in order to dampen the engine noise.
  • this exhaust air / air stream is then discharged via labyrinth ducts arranged in the hood of the vacuum cleaner.
  • corresponding protruding angles are provided on the side wall of the flow channel, which have bores through which screws pass, which screws are screwed into the top of the clamping plate.
  • angles in the flow housing itself can be integrated, the flow housing having, for example, holes in its base plate, through which screws can be screwed then also reach into the clamping plate.
  • An electric motor 31 is clamped in an easily replaceable manner between a lower carrier plate 32 and an upper clamping plate 33, the electric motor being held in a vibration-damped manner via rubber elements 34. From Figure 1, the turbine 35 of the vacuum cleaner can also be seen, which is placed directly below the actual electric motor 31.
  • the flow of the engine cooling air is indicated in FIG. 1 with MK, the flow of the engine exhaust air with MA, the flow of the suction supply air with SZ and the flow of the suction exhaust air with SA.
  • a flow housing 1 for the engine cooling air according to FIG. 3 is open at the top and has an upper edge 21.
  • the upper cover of this housing 1 with respect to the upper edge 21 is formed by the inside of the hood of the vacuum cleaner, not shown. This means that the housing 1 is closed on all sides and only has one connector 2 and the other connector 17.
  • the wall 19 which is approximately angled in plan view, is omitted and this wall 19 is itself formed by the wall of the hood or the clamping plate of the vacuum cleaner.
  • the flow-through housing 1 is only flowed through by the engine cooling air.
  • the turbine intake air and the turbine exhaust air are routed separately in the exhaust air ducts between the clamping plate and the carrier plate.
  • the present invention is therefore about the guidance of the engine cooling air and the arrangement of the electronic circuit parts in the area of this flow housing.
  • FIG 3 is shown schematically that the housing essentially (see Figure 4 and Figure 5) consists of two sockets or legs 2.17, which form a mutual distance from each other.
  • a heat sink 3 with cooling fins 4 is arranged in the connecting piece 2, transistors 8 being firmly connected to the heat sink 3 on the side faces of this heat sink.
  • This heat sink is therefore fully in the flow of the intake cooling air, which enters the nozzle 2 from below in the direction of arrow 12.
  • the cooling air occurs here in several cross sections, namely once in the gap 9 between the heat sink 3 and the outer wall 19 of the housing, further in the gap 10 between the back of the heat sink 3 and the back of a circuit board 6 and also in the gap 11 between the front of the Board 6 and the inner wall of the connector 2.
  • the wall 19 can be omitted and appropriate sealing measures are then provided at position 22, because then in this area the connector 2 rests air-tight on the inside of the hood and the connector 2 on the one hand through the wall of the hood and on the other hand through the remaining walls of the housing 1 is formed.
  • This circuit board 15 essentially carries the mains rectifier 16 with heat sinks, cooling fins and the like. Components to be cooled more.
  • the air then flows in the direction of the arrow 18 and then flows into the nozzle 17, where the nozzle on its lower edge 23 is also air-tight is connected to the fixed part of the motor so that the air in the direction of arrow 18 then flows through the winding of the motor.
  • the electronics to be cooled could also be arranged directly on the clamping plate and in the incoming cooling air flow of the motor.
  • appropriate electronic parts to be cooled can also be arranged in this area, such as, for. B. a mains interference filter, an automatic switch-on and switch-off for switching the vacuum motor on and off in the event of a fault, and an automatic switch-off for switching off a tool, which is then switched off when the vacuum cleaner falls below a certain minimum volume flow.
