Definitions
- This invention relates to a washing apparatus for floors, walls and ceilings for use in private homes, schools, hospitals and such like, as described in the introductory part of Claim 1.
- Machines for washing come in numerous designs. Most of the known machines are designed for washing floors.
- US Patent Specification 1 464 031 describes a floor washing machine with rotating brushes. It includes two sets of brushes, where the brushes in each set work in opposition so that water is thrown upwards and collected in a central container. The two brushes in the respective sets are best considered as squeezing rollers, since they work by pressing the water out of each other.
- US Patent Specification 3 061 859 also describes a floor washing machine that is particularly designed for carpeted floors. This known machine is pushed across the floor surface by changing the weight-loading on one roller or the other. This is done by a handle. This known machine has no water container to receive water as it is intended to be used with foam.
- US Patent Specification 4 654 916 also describes a machine with rollers that works on a floor surface.
- the rollers or brushes force dirt to rise between the brushes and be led into a container.
- Swedish Printed Publication 362 349 describes a cleaning machine that is also based on the vacuum principle.
- machines for washing There are many drawbacks with existing machines for washing. They are often complex in design and are usually large. They are normally intended for use in sizable rooms so that their bulk is not a severe drawback. Some machines are equipped with a seat for their operator. None of these types of machines for washing are designed for use on walls, ceilings etc.
- the market for such machines has traditionally been wealthier groups where price has not been the dominant factor, rather getting the job done quickly with satisfactory results. Market considerations and the complexity of these machines have resulted in relatively high prices. This has meant that the huge potential market comprising private homes, small offices and the like, has not been interested in buying such machines for washing.
- the main objective of the invention is to design a machine for washing, that is primarily intended for floors, walls and ceilings and which can effectively wash by using a fluid, preferably water, that can be removed after use.
- the invention is to be manufactured at such a reasonable price that there will be a market among private homes and smaller offices.
- a second objective with the invention is that it must be compact and able to be used in places where traditional washing appliances find it difficult to reach.
- FIGs. 1 and 2 show a schematic lateral perspective sketch of an existing machine for washing
- Fig. 3 shows a schematically and partially sectioned lateral perspective of a straightforward prefered embodiment of the invention
- Fig. 4 shows a cross section of a second embodiment of the invention
- Fig. 5 shows a cross section of a third embodiment of the invention.
- Fig. 1 shows an embodiment of an existing washing apparatus 1 which is placed on a surface 2.
- the washing apparatus 1 consists of a handle 3 which is flexibly connected to the washing apparatus 1 at a point 4.
- the washing apparatus 1 is connected by a tube 5 to a water tank 6 that is consequently to be understood as part of the washing apparatus 1.
- the water tank 6 contains a washing agent and has a chamber 15 for clean water and a second chamber for dirty water 16.
- the tank 6 is equipped with wheels 7, so that it can be rolled on a surface 2, floor, wall, ceiling or the like, depending on the task the washing apparatus 1 is to be applied for.
- the washing apparatus 1 is also equipped with one or more cylindrical roller brushes 8,9.
- the roller brushes 8,9 are driven by a motor 11 which by means of a transmission 12 transfers power to the washing drums.
- the handle 3 is equipped with appropriate means 13, 14 of controlling the washing apparatus 1, preferably switches or regulators 14 for start/stop and speed, and a brake 13, that can also be used to lock the handle.
- the detail drawing of the washing apparatus 1 in Figure 3 shows an example of a prefered embodiment of present invention.
- the apparatus 1 is intended for the washing of floors, walls and ceilings.
- This apparatus is connected to a water tank that is either on wheels or is portable.
- the apparatus has a roller brush 8 that works towards an intermediate tank 10 for the collection of dirty water and sand particles.
- the intermediate tank 10 is designed to retain the water it contains, in all, or at least most directions, this facilitates the washing of floors, walls and ceilings.
- the intermediate tank 10 is a container that is sealed in all directions apart from an opening on the side facing the roller brush 8. This enables fluid to be transferred from the surface 2 by means of the roller brush 8 to the intermediate tank 10.
- the fluid is held in the tank irrespective of its position, enabling floors, walls and ceilings to be washed.
- an elastic dustpan 20 which has a plough-shaped leading edge facing downwards to make it easier for the rollers to move the washing water, dirt and particles from the floor into the intermediate tank.
- the dirty water is then pumped into a tank for effluence.
- Above the intermediate tank there are reversible wipers 18 that help remove the remaining water and particles from the roller brushes.
- the control handle 3 is hinged on the apparatus so that there is no real front or back to the device, and it can be moved either way with equal ease.
- the control handle can also be completely horizontal so that washing can be done under low furniture or other places with difficult access. Clean water is supplied through a nozzle 17 onto the surface that is to be washed.
- the water supply and the washing roller can be started and stopped by means of the buttons 14 on the control handle 3.
- Fig. 4 there is an embodiment of the invention where the dustpan is replaced by a sweeping brush 9. This is done to facilitate the washing of uneven surfaces, where the dustpan could not be brought in proper contact with the surface.
- the sweeping brush 9 does not necessarily have to be in contact with the roller brush 8.
- This embodiment of the invention can also be used for floors, walls and ceilings since it is equipped with an intermediate tank and reversible wipers.
- the drive motor can be fitted to the handle to make the apparatus lighter.

Abstract
Un appareil de nettoyage (1) comporte au moins un rouleau laveur (8, 9) rotatif et généralement cylindrique, là où se trouve l'unité rouleau laveur (8, 9) de sorte qu'il puisse être mené avec son axe de rotation généralement parallèle à une surface (2) devant être nettoyée. En outre, l'appareil (1) comporte un manche (3) qui sert à déplacer l'appareil, ainsi qu'un moteur qui fait tourner les rouleaux laveurs (8, 9) lorsqu'ils se trouvent en contact avec une surface (2). Il y a également un ou plusieurs ajutages (17) qui servent à pulvériser du liquide de nettoyage, de préférence de l'eau pure, sur la surface (2). Le liquide de nettoyage est enlevé de la surface en même temps que la saleté et les particules au moyen de rouleaux laveurs (8, 9) et mené à un réservoir intermédiare (10). Le réservoir intermédiare (10) est un récipient entièrement étanche à l'exception d'un orifice du côté de l'unité rouleau laveur (8). Cette configuration retient le fluide dans le réservoir intermédiaire (10) indépendamment de sa position, permettant ainsi le nettoyage des sols, des murs et des plafonds.A cleaning apparatus (1) has at least one rotatable and generally cylindrical wash roll (8, 9) where the wash roll unit (8, 9) is located so that it can be driven with its axis of rotation generally parallel to a surface (2) to be cleaned. Furthermore, the device (1) comprises a handle (3) which serves to move the device, as well as a motor which rotates the washing rollers (8, 9) when they are in contact with a surface ( 2). There are also one or more nozzles (17) which serve to spray cleaning liquid, preferably pure water, onto the surface (2). The cleaning liquid is removed from the surface together with dirt and particles by means of washing rollers (8, 9) and led to an intermediate tank (10). The intermediate tank (10) is a completely sealed container with the exception of a port on the side of the washing roller unit (8). This configuration retains the fluid in the intermediate tank (10) independently of its position, thus allowing the cleaning of floors, walls and ceilings.
