Definitions

• the present invention relates to a device for a handheld scrubbing machine for floors and similar surfaces and that comprises at least one driven rotatable scrubbing-brush or similar floor-cleaning roller arranged to scrub the floor while simultaneously supplying liquid to the scrubbing-brush.
• a device for a handheld scrubbing machine for floors and similar surfaces and that comprises at least one driven rotatable scrubbing-brush or similar floor-cleaning roller arranged to scrub the floor while simultaneously supplying liquid to the scrubbing-brush.
• the main object of the present invention is primarily to solve, among others, the problem mentioned above by simple and efficiently functioning means.
• a device which essentially is characterized in that supply means for supplying scrub liquid to the area of said scrubbing-brush and the subjacent floor before starting the rotatable scrubbing-brush is arranged to be actuatable by a mechanism that effects the supply of scrub liq- uid during a certain period of time before rotation of the scrubbing-brush starts.
• Fig. 1 shows a scrubbing machine according to the invention as seen laterally
• Fig. 2 shows the machine as seen from below.
• Said device 1 comprises a mechanism 9 that consists of supply means to allow the supply of scrub liquid 7 to the area 8 of said scrubbing-brush 5 and a subjacent floor 3 before starting the rotatable scrubbing-brush 5.
• Said mechanism 9 is arranged to effect the supply of scrub liquid 7 during a certain period of time before rotation of the scrubbing-brush 5 starts. Thereby, a good start for the machine 2 is obtained without the scrubbing-brush 5 being run dry and risking damag- ing subjacent floors 3 and also itself being worn.
• Said supply mechanism 9 comprises a delay unit arranged to provide delay of the start of the rotation 10 of the scrubbing-brush.
• the delay unit consists in turn of a micro controller including a timer.
• Said delay unit is arranged so that it can actuate the electrically driven motor 11 of a pump 12 for supply of scrub liquid 7 when the set correct instant of time is reached.
• the delay mechanism is arranged to start the flushing at between 5-10 s using much liquid 7, approx. 0,5 1/min, before the motor 4 that drives the scrubbing-brush 5 is actuated to start to rotate in the intended direction of rota- tion 10.
• Said delay mechanism is set at approx.
• a said scrubbing machine 2 supports pref- erably at least one tank 15 for storage of clean scrub liquid 7 as well as an electrically operating driving unit 4 and 11, respectively, for a scrubbing-brush 5 rotatably driven around a vertical axis 6 and a pump device 12 for supply of scrub liquid 7 to the scrubbing-brush 5 as well as a suction device 13, for instance a suction pump 13, for suction of slops 14 from the floor 3 within a suction protection formed by a circular stop 16, in the form of a plurality of turnably mounted flexible rubber or plastic tongues, and for storage of the slops in a separated tank 20.
• Supply of scrub liquid 7, which may consist of water mixed with a cleaning agent, e.g., soft soap, is arranged to be effected from the area of the central centre 5A of the scrubbing-brush via a conduit 17.
• a said supply unit 12 is arranged to supply scrub liquid 7 to an area 18 entirely surrounded by the rotatable bristles, etc., 19 of the scrubbing-brush.
• the scrub liquid 7 is preferably arranged to be sprayed out radially from the centre 5A of the scrubbing-brush, but the liquid 7 may simply also be arranged to flow out freely on the floor 3 at the area under said resting scrubbing-brush 5, if the machine 2 now is arranged to be held still before the scrubbing starts.
• the machine may be arranged in a plurality of parts where a rear, so-called tank part may be detachably coupleable to said scrubbing-brush-supporting front part of the machine. It is then possible to easily supply new scrub liquid when the previous is finished by simply shifting tank parts.
• the driving is suitably carried out by electricity from the mains, which means that an electric cord connects to the machine 2 and the elec- trically driven units thereof, but also environmental-friendly battery operation or other operation may be feasible.
