Definitions
- the invention relates to a suction hood on wet floor cleaning machines for primarily commercial use; it is based on a device as described, for example, in US Pat. No. 4,817,233.
- the object of the present invention is therefore to provide a construction or arrangement with respect to the suction hood which also enables the scrubbing roller to move fully towards the edges of the room and thus to completely clean such floor surfaces.
- the scrubbing roller is mounted on a only one-end clamped, that is, on a so-called free arm axis b) the suction hood is axially displaceably mounted or guided relative to the scrubbing roller on the machine frame.
- the suction hood can thus "retract" at the edges as far as possible with the brush roller at the edges up to the vertical right level of the free scrubbing roller end face and thus enable the edge surface in question to be cleaned with exact edges while maintaining the full suction effect.
- Fig. 1 shows a floor cleaning machine schematically in side view
- Fig. 2 is a view of the machine from below.
- the floor cleaning machine X indicated purely schematically in FIG. 1, has in its front region a scrubbing roller 3 with an overlapping one Suction hood 2; the entire cleaning process with water supply, scrubbing and dry vacuuming is thus carried out in a manner known per se in the front area of the machine.
- Combinatorically new here according to FIG. 2 is that the motor-driven scrubbing roller 3 rotates on a (free-arm) axis which is only clamped on one side within the suction hood 2 which covers it on both sides at the front side, this suction hood 2 leading axially displaceably relative to the scrubbing roller 3 is.
- a (parallelogram) linkage 4, 5 with return spring 6 is used as a guide element for the axial displacement of the suction hood 2, linkage 4, 5 and return spring 6 on the machine bottom la are exposed or protected inside the housing.
- any other form of linear guide of the suction hood 2 can be used and instead of the return spring 6 any other known type of alignment elements.
