Description

Cleaning and surface treatment devices They are mechanically acting Cleaning devices known, which with the help of rotating brushes and partly also work with a simultaneous supply of air. Mostly these are devices for processing larger curses, e.g. B. Floors. These devices all have the Disadvantage of being specialized for a specific purpose, which has to be ho'lge, that with a limited edition number in the production too. the selling price right is high. For cleaning and polishing work in households and businesses there is a strong need for an inexpensive device which if possible several operations combined in one. It doesn't just have to be from such a device be demanded that it saves work, but also better execution same guaranteed. The device described below fulfills the aforementioned Demands by requiring intensive mechanical cleaning by means of various, generally high-speed rotating brushes with a simultaneous supply of a liquid one or dusty cleaning or polishing agents and warm or cold air as Desiccant causes.

In B41, diagrams i to 6 are exemplary embodiments from to devices working according to this principle. Here picture i shows a device with directly attached motor, Figure 2 the supply of the liquid cleaning agent, Fig. 3 a device with a separate motor and flexible hose for the transmission of rotation and supply of detergents and desiccants; Picture 4 represents a device for the distribution of the dry cleaning and polishing agent dar; Figure 5 illustrates a similar device with Figure i, but with back and forth walking brushes; Figure 6 shows the design of a brush for a device according to Figure 5.

On the basis of the images listed above, the Embodiments of the device are described.

According to Fig. I, the drive becomes a normal, usually very small one and lightly held universal motor with housing i, armature 2, field windings 3, Axis 4, brushes 5 and brush holder 6 used. Wave 4 drives this in all directions closed housing 9 located bevel gearbox io, which via the hollow shafts i i the rotary movement of the brushes 14 fitted onto the bushes 13, their shape according to the intended use, e.g. B. can also be selected according to Figure i a, forwards. Bushing 13 and brush 14 have common holes 15. Through here Means not shown in detail, such as bolts, grooves and tongues, etc., will take care of this worn that the holes 15 always fit together. As soon as the engine is running, 8 air is driven in direction A-B by the fan 8 seated on shaft 4. By guide element 12, the air is either in the desired manner to processing object or guided under the rotating brushes 14. On his way the air flow passes the heating resistance ring 16, which simultaneously with the Motor or a special switch, not shown here, switched on and gives off its heat to the passing airflow.

Figure 2 shows the container 17, not visible in Figure i, with a lid 18, which contains the cleaning and polishing liquid i9.

After turning 17 upright and opening the needle valve 20 through By turning the knob 21 to the left, the liquid flows out through the tube 22. Between the bevel gears of the back gear io the tube 22 forks and ends in the central one Bores of the shafts i i. In this way the liquid gets inside of the brushes 14 and is hot rotation of the same through the holes 15 between the Brush hair and pressed onto the workpiece. The hydration can through Tilt the device by 90 ° around the shaft axis i i or by turning the knob to the right 2i are interrupted.

If the engine is more powerful, the weight of the device, especially when working on vertical surfaces, are perceived as annoying. In this case a version according to Figure 3 with the machining head separated from the motor is more appropriate. Both are through the flexible hose flanged to the motor housing i, 29, which the flexible shaft 24 inside the cleaning medium hose 25 contains, connected. Shaft 24 is driven by motor axis 4 and transmits the rotation via the Bushing tube 26 on the bushing brush 27 on which brush 14 is fitted. That liquid cleaning agent i9 is added to the container 17, 18 after the needle valve has been opened 2o removed and flows into the hollow cylinder 30, which is closed on the motor side which hose 25 is drawn on the outside. The spiral windings of the flexible ones work here Shaft 24 at the same time as a screw conveyor and transport the cleaning agent itg through the bores of the tubular sleeve 26 into the brush cavity. By centrifugal force the cleaning agent is pressed against the conical walls of the brush 14 and passes through the bores 15 into the brush hair and so into the open.

The air flow is through the cavity between the detergent hose 25 and outer hose 22 and the openings 28 passed through the funnel-shaped Guide element 23, pressed in direction B against the brush hair. Guide element 23 can be made of rigid or flexible material and in various designs interchangeable depending on the intended use.

When working with a device of this type, the motor can either be stuck stand or with the help of a support or clamping device in any way that adapted to the work to be performed.

In many cases there is a need to atomize a powder detergent. An additional device suitable for this is shown in Figure 4: A hollow body 31 with the bores 32 is placed on the motor housing i. On the motor side, the hollow body 31 is closed off by a sieve 33, which rests on the gear housing 9, and a leather membrane 34. When the air moves in direction A-8, 34 is raised in a ring shape by the air flow and forms a hollow cone which contains the cleaning agent 35 . The air passing by generates eddies which carry part of the powder 35 with it, so that it passes through the openings 32 into the open.

In some cases the brushes can move back and forth better suited to the work to be done than a rotating one. Pic 5 shows an embodiment of such a device in plan and side elevation: motor shaft 4 en.d@igt in an eccentric 36 which, when 4 is rotated, the resettable by springs 38 Plunger 37 sets in motion. These are firmly connected to the brushes 14. By doing In this exemplary embodiment, Figure 6, the brushes contain the cleaning agent i9, which through holes in the brush hair and thus on the to be processed Object arrives.

The detergent supply is interrupted by moving it the closure plate 39 by means of the rotatable eccentric 40 via the adjusting screw 41.

The reciprocating movement of the brushes 14 can with the elimination of the motor Drive also achieved by a simple alternating current fed electromagnet will. Such an arrangement has the advantage of being particularly cheap.

The possible uses of the devices described are numerous. The work of cleaning windows z. B. is greatly facilitated by them. For repolishing <instead of the brushes, buffing buffers can be used.

Brushes made of Nlessine and steel wire are used for cleaning stoves used as these also remove the dirt from the grooves. Ilerdhlatten are also to polish with it.

Furniture with embellishments is cleaned with soft brushes and optionally polished by means of a liquid polishing agent. The device is especially in the industry for polishing the wood to be processed for polished Furniture to use.

Circrade the latter work requires, handcrafted, especially much time. Here, too, z. B. when polishing furniture, polishing to a high gloss done by putting on a fabric buff. Simultaneous feeding of hot air at the end of the work process promotes evaporation of the last Residues of the liquid components contained in the polishing agent.
