Abstract
The invention relates to a device (1) in connection with a floor cleaning machine functioning with liquid. According to the invention a combined hub (5) for supporting a brush/disc (6) of a floor cleaning machine has three functions, viz. A: as a hub for a brush/disc for holding the same, B: as a distributor for the distribution of liquid to said machine, radially from the outside towards the centre of the hub, and C: as a distributor for the distribution of vacuum to said machine in order to suck up washing liquid from the machine.
Description
Device in connection with a floor cleaning machine The present invention relates to a device in connection with a floor cleaning machine functioning with liquid.
As far as known floor cleaning machines and other similar machines functioning with liquid are concerned, the feeding of water is brought about in the centre of a rotatable brush or another floor treating tool. However, when such feeding of water in the centre is used, dirt has a tendency to accumulate easily and finally get stuck in the water inlet tube, which results in interruption of the functioning of the machine.
There are solutions in that washing liquid is supplied to the hub of a floor cleaning machine through a central tube and then is spread radially through radial spreader tubes. As examples thereof it is referred to US 6,052,854 A, US 5,711,051 A, US
2009/0260177 Al, and US 5,970,574 A. However, the washing liquid is still supplied centrally through a hose or a tube at the risk of clogging and stop in said tube or hose as a result.
Known solutions require complicated means in order to attach the rotatable brush, etc, of the machine, and suction means to suck up dirty washing liquid from the floor after the washing with machine. In this connection it is i.a. referred to the patent publications mentioned above, and also to GB 2 345 241 A.
A known compact hub, which comprises channels for the distribution of vacuum to said machine in order to suck up washing liquid, does not allow efficient deflection in intended direction, but whirls and other unwanted effects are formed.
SE 529 868C2, owned by the present applicant, concerns a water suction device in a combi cleaning machine comprising three suction nozzles (11), which are surrounded by blades (12, 13) in one of their respective ends, for catching waste water and suction.
The water, which is conducted radially in the known machines, does not constitute distribution of liquid, but instead it is washing liquid which is conducted towards the centre of the hub (18) of the brush to be forwarded to a waste water container (25) through a hose (24).
Clean washing water is supplied through an axial tube (14), which may, of course, be clogged easily.

Clean washing water is supplied through an axial tube (14), which may, of course, be clogged easily.
2 Consequently, the main object of the present invention is first of all to among other things solve some of the problems described above by means of a device designed for that purpose.
Said object is achieved by means of a device according to the present invention, which is mainly characterized in that a combined hub for supporting a brush/disc of a floor cleaning machine has three functions, viz. :
A: as a hub for a brush/disc for holding the same, B: as a distributor for the distribution of liquid to said machine, radially from a circumference towards the centre of the hub, and C: as a distributor for the distribution of vacuum to said machine in order to suck up washing liquid from the machine, whereby the hub comprises a movable channel for the water supply, and which is arranged to rotate with the hub and conduct the water radially from the circumference and towards the centre of the hub to be discharged axially in downwards direction, that a releasable plug is fastened in the centre, which comprises channels arranged to redirect the air flow about 90 , that said plug comprises a plurality of channels arranged with double bends, so that they firstly extend horizontally, and which then via obliquely upward extending channel portions I 7A pass into upwards directed channel outlets 17B to drain off sucked-up washing liquid, and that a suction ring for the suction of washing liquid from the floor is so positioned, that it surrounds the brush and may be attached to a rotary central shaft by means of a number of springs and said hub.
The hub in question, which is adapted for a brush/disc of a cleaning machine, has preliminary three functions: to distribute clean water, to distribute vacuum for the suction, and to be an attachment for the brush. It has a concentric water feeding system which is based on a movable channel which rotates with the hub and conducts the water past a spring system and vacuum hoses. The channel is fed through a nozzle through the chassis. Then, the water is conducted through the hub and is spread down on to the floor in the centre of the brush.
The hub replaces a previous variant with water feeding in the centre through a tube,

The channel is fed through a nozzle through the chassis. Then, the water is conducted through the hub and is spread down on to the floor in the centre of the brush.
The hub replaces a previous variant with water feeding in the centre through a tube,
3 where the problem was that dirt accumulated easily and got stuck in the water feeding tube. By moving the water feeding radially outwards that problem was eliminated.
However, a type of cleaning machine is provided with a suction ring which is placed round the brush, which is attached to the rotary shaft by means of springs and the hub. These springs, and also the suction tubes, cause that the water must be conducted through a channel down under the brush in order not to sprinkle and disappear in the wrong place.
The hub now also exhibits a removable plug in the lower part, which makes it easy to clean, and which redirects the air flow for the suction about 900 with minimum flow losses.
The invention will be described in the following with reference to the accompanying drawings, in which:
Fig. 1 is a perspective view of a hub seen from above, which is adapted to be mounted on a floor cleaning machine and which exhibits brush and hoses, Fig. 2 is a perspective view of only the hub, Fig. 3 is an exploded view of the hub, Figs. 4 and 5 illustrate the hub seen obliquely from above and obliquely from below, respectively, Fig. 6 illustrates a floor cleaning machine adapted to support a hub in question, Fig. 7 illustrates the hub supported by such a floor cleaning machine in active position, Figs. 8-11 illustrate the hub in different positions and with included parts, Figs. 12-13 illustrate a part of a floor cleaning machine with the hub mounted therein, Fig. 14 illustrates the air flow when washing liquid is sucked up, and Figs. 15-16 illustrate the supply of water to the washing part of the machine.
