- the process air guiding device 144 further comprises the suction channel (s), which lead from the suction orifices 54 to the blower 34.
- the process air guiding device 144 comprises the suction channel 44 with the regions 46, 50 and 52.
- the process air guiding device furthermore has a process air outlet 148, which is arranged in particular on the housing 28 in the area of the blower 34.
- the process air outlet 148 has one or more openings, which are formed in particular by slots. About him is “spent"
- the process air guiding device 144 has (at least) a suction path 150, in which negative pressure conditions prevail in a cleaning operation.
- the at least one suction path 150 is formed in particular in the first region 46.
- cooling air guiding device 112 is coupled to the process air guiding device 144.
- the at least one channel 130 opens into the suction channel 44 and thereby into the suction path 150.
- a corresponding mouth region 152 lies in particular in the height of the suction device 32.
- this mouth region 152 which is a coupling region of the cooling air guiding device 112 into the process air guiding device 144, follows the separator 38. As a result, cooling air, which is formed by a pure air flow, does not have to pass through the separator 38.
- the corresponding injection point (the mouth region 152) is connected upstream of the separator 38.
- At least one rib 170 is positioned in the suction path 150 associated with the mouth region 152.
- the fin 170 is aligned parallel to a main flow direction of the suction flow in the suction path 150, the main flow direction being particularly substantially parallel to the longitudinal axis 20.
- the rib 170 is a type of orifice which shields, to some extent, an orifice 174 of the orifice area 152.
- the rib 170 may advantageously also be arranged and designed such that an air flow out of the cooling air guiding device 112 as it flows into the suction path 150 passes through it and in particular is deflected.
- a blocking element 176 is arranged at the mouth region 152.
- the blocking element 176 is connected in the mouth region 152 to the channel 130 and has a region 178, with which it projects into the suction path 150. This region 178 forms a projection of the cooling air guiding device 112 in the suction path 150.
- the blocking element 176 is, for example, a tube (tube). It is preferably made of a rubber material.
- the mouth 174 of the cooling air guide device 112 is located on the region 178 of the locking element 176. The mouth 174 is thereby spaced from a wall 180, at which the channel 130 ends. It protrudes into the Saugweg 150.
- the blocking element 176 also ensures that the risk of liquid drops from entering the cooling air guiding device 112 (into the channel 130) is reduced.
- a drainage channel 188 for liquid opens in a region 186 (junction region) of the suction path 150 which lies at the mouth region 152.
- the drain channel 188 leads downward from the junction area 186 with respect to the direction of gravity when in a normal mode of operation the surface cleaning machine 10 is placed over the cleaning roller 18 on the surface 16 to be cleaned. Through the drainage channel 188, liquid that would otherwise accumulate in the region 186 may drain.
- the (at least one) rib 170, the blocking element 180 and the drainage channel 188 contribute to greatly reducing the risk of liquid drops from the suction flow in the suction channel 150 into the cooling air guiding device 112 at the mouth region 152. Subsequent to this mouth region 152, the process air guidance device 144 and the cooling air guidance device 112 have the same fluid paths.
- the blower 34 forms a drive for the flow of cooling air through the cooling air guiding device 112. Cooling air is sucked through the cooling air guiding device 112 through the mouth region 152, which opens into the suction path 150, driven by the blower 34.
- FIG. 8 schematically shows an arrangement in which the cooling air guiding device 112, which is assigned to the drive motor 78, and the process air guiding device 144, which is assigned to the suction device 32, are completely separate from one another.
- FIG. 9 schematically shows the solution according to the invention described above. Cooling air is coupled via the cooling air inlet 114 in the surface cleaning machine 10, the drive motor 78 supplied to the air cooling. Discharged cooling air is coupled into the process air guiding device 144 and decoupled together with process air at the process air outlet 148.
- the direction of flow is reversible; this is shown in Figure 9 by the arrows in broken lines. It is possible in principle for a common inlet for cooling air and process air to be provided instead of a common outlet for cooling air and process air. It is then decoupled from the process air cooling air and fed to the drive motor 78.
- the above-described cooling air inlet 114 then forms a cooling air outlet.
- the corresponding system of the air guide with the cooling air guiding device 112 and the process air guiding device 114 has only one inlet 154 and only one outlet 156. Air is introduced via the inlet, which is initially used as process air. This air is then supplied as cooling air to the drive motor 78 and discharged at the outlet 156 back into the environment.
- cooling air from the drive motor 78 is coupled into the process air guiding device 144.
- the blower 34 of the suction device 32 provides for a corresponding intake of cooling air of the cooling air guiding device 112.
- Exhaust air of the drive motor 78 is coupled into the process air duct and discharged together with process air exhaust air to the environment.
- the inventive solution the number of openings that are needed for cooling air, in the immediate vicinity of the cleaning head 14 can be kept low. As a result, a high splash protection is achieved.
- the fan 34 with its fan motor 36 can provide a suction drive via which the drive motor 78 can be actively cooled by means of cooling air.
- the corresponding process air outlet 148 is also a cooling air outlet which can be positioned far from the cleaning roller 18 on the surface cleaning machine (relative to a cleaning operation). As a result, a high splash water resistance can be achieved. (The outlet region of the process air-guiding device 144 is anyway moisture-resistant.)
- a cooling air outlet can be positioned far away from the cleaning roller 18 and far away from the surface 16 to be cleaned in the case of a proper cleaning operation.
- the number of outlets can also be reduced if a cooling air outlet coincides with a process air outlet.
- the surface cleaning machine 10 of the present invention operates as follows. For a cleaning operation, the surface cleaning machine 10 is as shown in FIG.
- Figure 1 shown, supported on the cleaning roller 18 on the surface 16 to be cleaned.
- An operator stands on the surface to be cleaned 16 behind the surface cleaning machine 10 and holds it, for example, one-handed to the handle 24th
- a peripheral speed of the cleaning roller may be adjustable by an operator or for it to be fixed.
- the cleaning roller 18 has the trim 56, which is compressible.
- the trim 56 is in particular made of a textile material.
- the cleaning roller 18 is moistened directly with cleaning fluid from the tank device 42.
- this liquid admission is pump-free and in particular free of magnetic valves.
- an operator can make a corresponding adjustment in order to allow cleaning, for example, under furniture or the like.
- Relatively heavy drive motor 78 is located low down close to cleaning roller 18 with respect to a normal operating mode and is positioned at least partially against hinge 62 to save space.
- a cooling air outlet can in turn be positioned far apart from the cleaning roller 18.
- Cooling air outlet 138 Upper area
