Definitions

  • the task is therefore to provide a suction device with an improved cooling concept.
  • At least one cooling air channel has a permanently open flow cross-section
  • another cooling air channel has a valve, in particular a pressure-dependent valve.
  • the pressure-dependent valve sets the flow cross-section, for example the flow cross-section of the channel inlet opening, depending on a negative pressure, for example completely releasing the flow cross-section from a predetermined threshold value of the negative pressure. So, for example, if the negative pressure in the at least one cooling air channel increases because the suction inlet is not available or is available to a lesser extent, this pressure-dependent valve can release the channel inlet opening for the cooling air flow to flow through.
  • the channel inlet opening of the at least one cooling air channel is arranged on an outer wall, in particular on an outer edge area, of the suction device housing.
  • the cooling air can thus flow directly from the environment into the at least one cooling air channel.

  • control is designed to output at least one acoustic and/or optical warning when the motor characteristic falls below a predetermined threshold value that is associated with a minimum volume flow and/or a minimum flow rate of the suction flow.
  • the suction device has optical output means, for example a display, LEDs or the like, and/or acoustic output means, for example a loudspeaker, for outputting the warning.

  • Outlet openings 97 and 98 are used to remove the cooling air flows KL of the energy storage units 170 arranged at the device interfaces 90. These outlet openings are arranged close to the device interfaces 90 and thus close to the energy storage outlet openings 181 of the energy storage units 170 on the side walls 83 and 84 of the energy storage receptacle 81.
  • the outlet openings 97 and 98 are referred to below as receptacle outlet openings due to their arrangement in the energy storage receptacle 81 and are located close to the bottom wall 87, so that little or no heat builds up in the energy storage receptacle 81.
  • the intake/outflow opening 98 opens directly into a gap between the intermediate wall 30 and the filter element 13, so that a cooling air channel 99 is formed between the intermediate wall 30 and the filter element 13, which leads from the intake/outflow opening 98 to the flow opening 32 on the intermediate wall 30.
  • a cooling air flow KLA of the energy storage device 170 arranged on the side wall 84 can thus flow out of the intake/outflow opening 98 and is sucked away by the suction turbine 11 via the cooling air channel 99.

  • the energy storage device 170B can be cooled by a cooling air flow KLB, which can flow out of the energy storage device holder 81 through the receiving outflow opening 97.
  • the receiving outflow opening 97 forms a channel inflow opening 97A for a cooling air channel 100.
  • the suction turbine 11 is, for example, a so-called passage turbine or a turbine which is cooled or can be cooled by the suction flow it conveys.

  • a seal 11E is provided between, on the one hand, the intermediate wall 30 and, on the other hand, the front side of the suction turbine 11 facing the intermediate wall 30 and having the suction turbine inflow opening 11A, so that it lies tightly against the intermediate wall 30 and the suction flow S can flow through the flow opening 32, but does not flow into the suction turbine receiving space 31 in which the suction turbine 11 is arranged.
  • the suction turbine 11 has a schematically illustrated fan 11C and an electric drive motor 11D for driving the fan 11C.
  • the drive motor 11D is cooled by the suction flow S during normal operation of the suction device 10, i.e. when the suction flow S is flowing.
  • the power supply device 140 is arranged on a circuit board 104, which is arranged in a sandwich-like manner between the longitudinal side wall 28 and the side wall 83 of the energy storage receptacle 81 of the power supply device 80.

  • the cooling air channel 101 is fluidically connected to the intake/outlet opening 97. Air can thus flow into the cooling air channel 101 via the intake/outlet opening 97, for example the cooling air flow KLB. However, the cooling air flow KLB is already heated by the cooling of the energy storage device 170B.
  • Ambient air i.e. generally cooler air
  • the duct inlet opening 102 is arranged, for example, close to the bottom wall 25 on a region of the longitudinal side wall 28 facing the bottom wall 25.
  • a protective grille 102A is advantageously arranged on the duct inlet opening 102.
  • the cooling air flow KLC flows through the channel inlet opening 102 into a channel section 103A of the cooling air channel 101, which runs between the circuit board 142 and the side wall 31A.
  • the cooling air flow KLC therefore flows behind the circuit board 142 or the cooling air flow KLC flows past the circuit board 142.
  • the channel section 103A is selected such that the cooling air flow KLC essentially flows past the power supply device 140, i.e. in particular past the semiconductor elements 141, which become particularly warm when the suction device 11 is operated. However, such warming and, in the worst case, heating is effectively counteracted by the cooling air flow KLC.
  • the channel section 103A opens into a hose receptacle 104 in which a hose 110, thus a tubular body 110A for guiding cooling air, is accommodated.
  • the cooling air flow KLC flowing out of the channel section 103A is guided via the air guide surface 106 into an inlet opening 111 of the hose 110. There is a gap between the inlet opening 111 and the air guide surface 106 or the wall 107 so that the cooling air flow KLC can flow unhindered into the inlet opening 111.
  • a plug-in stop 105A is located opposite the plug-in receptacle 105, against which a jacket of the cooling air hose 110 can strike when plugged into the plug-in receptacle 105.

  • the inlet opening 111 cannot be closed by the air guide surface 106 because of the plug-in stop 105A.
  • the cooling air flow KLB can flow past the circuit board 142 and/or into the inlet opening 111 of the cooling air hose 110 in a gap between the circuit board 142 and the cover wall 34, so that the cooling air hose 110 guides both the cooling air flow KLB and the cooling air flow KLC in the direction of the channel outlet opening 108.
  • the cooling air hose 110 thus provides a common channel section 103B for the cooling air flows KLB and KLC.
  • the cooling air hose 110 has a hose section 112 which directs the cooling air flow KLC and/or the cooling air flow KLB to the suction turbine receiving space 31 to a channel outflow opening 108, which is arranged on the intermediate wall 30 and opens into the space between the intermediate wall 30 and the filter element 13. There, the cooling air flow KLC and/or the cooling air flow KLB can flow in the direction of the throughflow opening 32 in order to be sucked off by the suction turbine 11.
  • the hose section 112 has an arcuate shape. An end region 113 of the hose section 112 is held in the region of the channel outflow opening 108 in a receptacle 109, which is designed, for example, as a plug-in receptacle.
  • the cooling air channels 99 and 100 advantageously have smaller flow cross-sections than the cooling air channel 101.
  • the cooling air channel 101 cools the power electronics, e.g. the semiconductor elements 141. This measure helps to ensure that sufficient cooling air flows through the cooling air channel 101 and not, so to speak, past it through the cooling air channels 99 and/or 100.
  • a sensor 154 is arranged on the suction turbine 11, the sensor signals of which are evaluated by the controller 150.
  • the sensor 154 comprises or is, for example, a temperature sensor and/or pressure sensor and/or flow sensor. Due to the permanent cooling of the suction turbine 11 using the cooling air flows KLA, KLB and KLC, even when the suction flow S is interrupted is or is not flowing, there is sufficient flow pressure at the sensor 154 so that it can report valid temperature signals to the controller 150.
  • the required minimum speed of the suction flow S results in a minimum value VSmin for the volume flow of the suction flow S, which, for example, is approx. 10 l/s for a hose diameter of 27 mm of the suction hose SL.
  • the controller 150 can determine a characteristic curve VK of the volume flow of the suction flow S based on motor characteristic curves MK1 and MK2 as well as other motor characteristic curves of the drive motor 11D of the suction turbine 11 (not shown in the drawing), because both the characteristic curve VK and the motor characteristic curves MK1 and MK2 have a substantially constant, in particular substantially linear, course in the area relevant for monitoring the volume flow or the flow velocity of the suction flow S.
  • the motor characteristics MK1 and MK2 are dependent on voltages U1 and U2 with which the drive motor 11D is operated.
  • the motor characteristics MK1 and MK2 are proportional to a current profile of the motor current Imot with which the drive motor 11D is energized by the current supply device 140.
  • the controller 150 controls the current supply device 140 and receives from it as feedback, for example, the respective motor voltage applied, for example the motor voltages U1 and U2, as well as the respective motor current Imot for current supplying the drive motor 11D.
  • the controller 150 recognizes that the flow velocity of the suction flow S is too low and issues a warning on the display 157, for example. In this case, the controller 150 can alternatively or additionally also issue an acoustic warning on a loudspeaker or other acoustic output means 158.
