- an intake opening 140 is arranged on the jacket wall 134. Furthermore, a discharge opening 142 is arranged on the jacket wall. In the embodiment shown, an angular distance 144 between the suction opening 140, which in particular allows a tangential and / or spiral inflow, is about 300 °.
- a guide device 106 with one or more guide elements is provided in order to specify a defined flow direction.
- a storage device 146 is connected to the discharge port 142. Otherwise, the cyclone separator apparatus 130 functions like the cyclone separator apparatus 10.
- FIG. 10 An embodiment of a cleaning device, shown in FIG. 10 and designated 150, is a hand suction device.
- This hand suction device has, as mentioned above, a suction nozzle 72.
- the suction nozzle may be associated with a cleaning tool for the mechanical loading of a cleaning surface.
- this cleaning tool is designed as a lip 152 for removing liquid.
- the cyclone separator 10 is integrated.
- the axial direction 16 is at least approximately a horizontal direction with respect to the direction of gravity g.
- the suction nozzle 170 and the lip 152 are then arranged so that when used as intended with at least approximately horizontal orientation surface contact is made possible.
- the suction unit 42 is arranged at the cleaning device 150 spaced from the swirl chamber 12. Between the Unterbuchbeetzungs- connection 40 and the suction unit 42, a conduit 154 is arranged, which is formed for example by a pipe.
- the line 154 may be connected directly to the vacuum admission port 40 or this may be formed on the line 154.
- the suction unit 42 includes a suction fan 156, in which one or more wheels are driven by a fan motor 58.
- the fan motor 158 is, for example, an electric motor, to which a battery device 160 can be assigned, in particular with rechargeable batteries. Exhaust air 162 of the suction fan 156 is discharged to the outside.
- the suction unit 42 generates the necessary negative pressure, which generates the suction flow, which is "coupled” via the corresponding dip tube 28 into the separation chamber 22. There is an intake of dirt fluid, which is present at the suction nozzle 72, in the separation chamber 22. There, the cyclone flow is formed and separation medium is discharged via the discharge opening 74.
- the cleaning device 150 has a longitudinal extension direction 164, and the axial axis 16 is transverse and in particular perpendicular to this longitudinal extension direction 164th In one embodiment of a cleaning device 166 (FIG. 11), this has a longitudinal extension direction 168.
- the corresponding swirl chamber 12 of the cyclone separator apparatus 10 is installed so that the horizontal axis 16 is at least approximately parallel to the longitudinal extension direction 168.
- a cyclone flow is indicated by the reference numeral 170.
- the separation opening 74 extends essentially over the entire height H 2 of the separation space 22.
- a discharge channel 172 is arranged at the discharge opening 74. This has, for example, a tapering cross-section to a memory 174 out.
- the storage 174 is, for example, detachable on the cleaning device 166.
- the discharge channel 172 forms a type of collecting space, via which a discharge medium via a corresponding connection means 176 to the memory 174 can be issued.
- the discharge opening 74 is assigned a first storage 180, wherein a discharge channel is arranged between the first storage 180 and the discharge opening 74 182 may be arranged.
- the first memory 180 is followed by a second memory 184, wherein in particular liquid can flow from the first memory 180 into the second memory 184.
- the storage device 82 with the receiving chamber (s) 86 or 102 is preferably arranged below the delivery opening 74 in relation to the gravitational force direction g.
- the cleaning devices 166 or 178 it is then possible for gravity-driven discharge medium to flow from the discharge channel 172 into the storage 174 or from the discharge device. channel 182 into the first memory 180 and from there into the second memory 184.
- the cyclone separator device 10 or 130 according to the invention is fundamentally applicable to all cleaning suction devices for dry suction or wet suction.
- the aspirated fluid is a "dry fluid" of air and dirt particles.
- the dirty fluid is an air-liquid-particle mixture.
- the cleaning suction device may include or may be formed without a cleaning liquid applying means for the surface to be cleaned.
- the cyclone separator device can be realized compact, so that it can be advantageously used for hand-held devices and in particular hand-held devices or Stiehltechnik or sled devices.
