Definitions
- the invention relates to a hard-surface wiper device, in particular a window wiper, with a slit-shaped suction nozzle on which a flexible wiper lip is arranged, which projects forward over the suction nozzle.
- Such a window wiper is known for example from German utility model 80 19 169.
- a foam rubber-like wiping pad is located in a slot-shaped suction nozzle, and a wiper lip is also arranged next to this and independently of the slot nozzle.
- the suction effect is hindered by the foam-like wiping pad in the suction nozzle, so that a suction unit with particularly high power is necessary to maintain the necessary suction flow.
- the suction nozzle is therefore normally open, so that the suction flow can enter the suction nozzle unhindered.
- the wiper lip is bent in such a way that the suction opening is opened. If, on the other hand, the wiper is removed from the surface to be cleaned, the suction stream sucks the now free wiper lip onto the opposite wall and thereby closes the suction opening.
- this has the advantage that the necessary suction power of a suction unit connected to the wiping device is reduced when the suction opening is not in operation, and on the other hand it is also prevented with certainty that liquid can escape from the inside of the wiping device. even if the user holds the wiper with the suction nozzle down.
- the wiper lip projects through the suction nozzle, and is preferably arranged in the undeformed state between the two walls defining the suction nozzle.
- the wiper lip can thus be bent in one direction from its undeformed rest position when it is in contact with the surface to be cleaned are bent in the other direction in which it closes the suction opening when the wiper device is not in use and when the suction unit is switched on.
- the wall on which the wiper lip is mounted carries a support surface which extends in the direction of the front edge of the wiper lip and on which the wiper lip rests when it deforms in the direction of a complete opening of the suction nozzle is. This limits the movement of the wiper lip in the open position.
- the wiper lip which lies against this with a front edge when the surface to be cleaned is pulled off, is supported with its rear side on the support surface, so that the user can precisely dose the contact force of the front edge of the wiper lip on the surface to be cleaned , although the wiper lip is made of a flexible material.
- the support surface is preferably curved convexly in the direction of the front edge of the wiper lip, so that the wiper lip is not bent sharply at any point. This favors the flow properties of the suction flow in the area of the suction opening, in this way turbulence in this area is avoided.
- the supporting surface front edge and the front edge of the opposite wall are preferably arranged approximately opposite one another. They thus form the slit-shaped suction opening between them, with the suction opening on a wall is narrowed by the wiper lip resting on the support surface.
- This configuration makes it possible to precisely define the gap width between the front edge of the opposite wall and the surface to be cleaned, since the overall distance of the wiper device from the surface to be cleaned is determined by the front edge of the support surface and the wiper lip. This allows the suction properties in the area of the suction nozzle to be optimized.
- the wiping device can carry a wiping pad extending parallel to it, with which a cleaning liquid applied to the surface to be cleaned is optionally distributed under pressure and with which the surface to be cleaned is mechanically pre-cleaned.
- the wiper pad is arranged on the same wall as the wiper lip. In this way, when the surface to be cleaned is removed, the wiping pad is on the side facing away from it and does not hinder the removal process. To use the wiping pad, the wiping device is simply turned over so that the wiping pad then points in the direction of the surface to be cleaned. It is advantageous if the wiping pad can be fixed in a holder arranged on the wall at different distances from the wall. This makes it possible to replace the wiping pad, for example if wiping pads of different hardness are desired. On the other hand, by arranging the wiping pads at different distances from the wall of the wiping device, ergonomic aspects can be optimally taken into account.
- a particularly simple interchangeability results if the wiping pad can be inserted laterally into the holder.
- the wiper device has a spray nozzle for applying a cleaning liquid to the surface to be cleaned, the spray nozzle preferably being arranged on the same side as the wiping pad. It is then possible to add cleaning liquid as required when cleaning the surface with the wiping pad.
- the spray nozzle can be detachable in a slide-in holder and can be fixed in a sealed manner with respect to the wiper device, so that it can be replaced at any time simply by pushing in or pulling out.
- nozzles with different spray characteristics can be used, for example point jet nozzles for vigorous pre-cleaning and flat jet nozzles for uniform application of the cleaning liquid to a larger area.
- An actuation button for the spray nozzle can be arranged on the side of the wiper device opposite the spray nozzle, it being advantageous if a switching element for switching on and off a suction unit generating the suction flow is arranged next to the actuation button.
- the wiper device is at least partially transparent in the part located downstream of the suction nozzle.
- a display element which is visible from the outside and can be moved into different positions depending on the strength of the suction flow is arranged in the interior of the wiper device. If there is no suction flow, this can be easily recognized by the different position of the display element compared to the suction flow switched on.
- the wiper device can be widened in the area of the suction nozzle by an attachment piece in which the suction nozzle continues. It is advantageous if the wiper carries a removable end wall on its lateral end faces, in the place of which the attachment piece can be fastened.
- a telescopically extendable suction pipe can be connected to the suction nozzle. This can be locked, for example, in the extended position, so that it is automatically pulled into the shortened position when the lock is released and the suction opening is closed by the wiper lip.
- FIG. 1 a longitudinal sectional view of a wiper device resting against a window pane
- Figure 2 is a plan view of the front part of the wiper of Figure 1;
- FIG. 3 shows an enlarged longitudinal sectional view of the wiper device in the area of the circle A in FIG. 1 with the suction flow switched off;
- FIG. 4 a view similar to FIG. 3 with the suction flow switched on and when the wiper device is not in contact with a surface to be cleaned and
- FIG. 5 shows a view similar to FIG. 4 when the wiper device is in contact with a surface to be cleaned.
- the wiper shown in the drawing is primarily intended for cleaning window panes, but it is also suitable for cleaning other hard surfaces.
- the wiping device comprises a suction head 1 with a flat upper wall 2 and a lower, flat wall 4, which extends at an acute angle from the front edge 3 of the upper wall 2, the front edge 5 of which coincides with the front edge 3 of the top wall 2 forms a slit-shaped suction nozzle 6.
- the suction head 1 delimited by the upper and lower walls 2 and 4 is delimited by lateral wall parts 7, which are detachably fastened to the walls 2 and 4, for example by means of elastic locking.
- the wall parts 7 can be removed in this way; in their place, lateral extension pieces 8 can be tightly connected to the walls 2 and 3, which continue the suction head 1 laterally and in this way widen the suction head 1 and in particular the suction nozzle 6 ( Figure 2).
- the width of the suction nozzle 6 can be varied in this way either by using no attachment piece or by attaching attachment pieces on only one side or on both sides.
- the suction pipe 9 is connected to a flexible suction hose 11, which leads to a suction unit in a manner not shown in the drawing.
- This suction unit is preferably operated by its own battery; it can also be operated by an electrical supply cable, for example from the battery of a motor vehicle. be fed.
- a control line 12 is provided, which leads along the suction hose 11 and the suction pipe 9 to a switch 13 in the suction pipe 9.
- This switch 13 is preferably designed as a button, so that when the switch 13 is pressed, the suction unit works, but when it is released it switches off.
- a pump which transports a cleaning liquid from a storage container via a supply line 14 to a spray nozzle 15 which is located in the upper wall 2 in the immediate vicinity of the connecting piece 10.
- This spray nozzle can be firmly connected to the upper wall 2, in a preferred exemplary embodiment it can be inserted in a corresponding holder, a seal being produced between the spray nozzle and the upper wall 2 by means of seals (not shown in the drawing). With such a construction, the spray nozzle can be easily replaced.
- the pump is switched on and off via a further switch 16 which is arranged next to the switch 13 on the suction pipe 9.
- This switch 16 is also preferably designed as a button.
- the control line 12 and the feed line 14 can run inside the suction hose 11, but it can also be provided that they emerge from the suction pipe at the transition from the suction pipe 9 to the suction hose 11, so that the suction pipe can be freely rotated relative to the suction hose.
- a suction container is also assigned to the suction unit, in which liquid sucked in via the suction hose 11 is collected.
- a central area 17 of the upper wall is transparent, thus forming a window through which one can look into the interior of the suction head 1 and determine whether liquid is being sucked in and, if so, what degree of contamination such a liquid has.
- a display element 18 which is rotatably mounted in the interior of the suction head 1. It has an airfoil-like profile and is thereby pivoted into a horizontal position by the suction flow, as can be seen from FIG. 1. If the suction flow is absent, on the other hand, the display element 18 hangs down.
- These different positions can be recognized from the outside, for example by the fact that in the horizontal case a colored surface of the display element 18 can be seen directly under the transparent upper wall 2, but in the case of the lack of suction flow this surface is not closed see is. You get a display element that the Presence of a suction flow and possibly also the strength of the same.
- This wiping pad can, for example, have a circular cross-section and consist of foam rubber which is in an egg is defined in cross section U-shaped bar 21.
- This bar 21 is inserted with laterally projecting projections 22 into opposite grooves 23 of two parallel walls 24 and 25 of the holder 19 (FIG. 1).
- a plurality of such grooves 23 are provided one above the other in the walls 24 and 25, so that the strip 21 can be inserted at different distances from the upper wall 2.
- the wiping pad 20 can also be arranged at various distances from the upper wall 2 of the suction head 1.
- the bar with the wiping pad can be removed easily by lateral displacement, so that the wiping pad can be exchanged as desired.
- This wiper lip 27 is laterally inserted with a bulged rear edge 28 into a corresponding recess 29 in the holding strip 26, the wiper lip 27 passing through a slot 30 which emerges from the recess 29 essentially parallel to the upper wall 2. In this way, the wiper lip 27 is secured against displacement in the longitudinal direction.
- the slot 30 is arranged such that the undeformed wiper lip 27 emerging from it is arranged parallel to the upper wall 2, approximately between the latter and the front edge 5 of the lower wall 4 (FIG. 3).
- the wiper lip 27 protrudes slightly beyond the front edge 3 of the upper wall 2, while the front edge 5 of the lower wall 4 is set back somewhat.
- the wiper lip 27 ends at its free end with a rectangular cross section, that is, there is a sharp front edge 31 on the underside of the wiper lip.
- the underside 32 of the holding strip 26 is formed in the part lying downstream of the slot 30 parallel to the lower wall 4, on the other hand this underside 32 is designed as a support surface 33 between the slot 30 on the one hand and the front edge 3 of the upper wall 2 on the other hand. which is slightly convex in this area.
- the underside 32 has the same shape over the entire length of the holding strip 26.
- the wiping device described is first used to spray the surface to be cleaned with a cleaning liquid.
- the spray nozzle 15 is directed onto the surface to be cleaned, and by actuating the switch 16, the delivery of the cleaning liquid is switched on. Cleaning chemicals can be added to the cleaning liquid.
- the surface to be cleaned is cleaned using the wiping pad 20, stubbornly adhering dirt being applied a corresponding pressure can also be solved mechanically.
- the wiper device is turned over, so that the wiper pad 20 points upward in the manner shown in FIG.
- the wiper is placed with the wiper lip 27 on the surface 34 to be cleaned, at the same time the suction unit is switched on by actuating the switch 13, that is to say a suction flow is generated in the suction head 1, through which ambient air is sucked in via the suction nozzle 6.
- the suction nozzle 6 Before the wiper lip 27 contacts the surface 34 to be cleaned, the suction nozzle 6 is still closed, an opening only occurs as soon as the wiper lip 27 bears against the surface 34 to be cleaned and by a movement of the entire suction head 1 downwards and upwards is bent over, that is to say is applied to the support surface 33 (FIG. 5). In this position, which is forced by the downward wiping action of the suction head 1, the cleaning liquid is sucked from the surface 34 through the then opened suction opening 6 into the suction head 1, at the same time the sharp front edge 31 of the wiper lip 27 slides on the Along surface 34 and strips cleaning liquid quantitatively from surface 34. After a single sweep, the surface is completely freed from the cleaning liquid.
- a very special advantage of this automatically entering closure of the suction opening is that the suction nozzle 6 is opened only in the area in which the wiper lip 27 is placed against the support surface 33 by the contact with the surface 34. If the surface 34 to be cleaned is uneven, such a wiping of the wiper lip 27 may only occur in partial areas; The suction nozzle 6 remains open only in those subareas in which an effective wiping effect occurs, whereas in the subareas in which the wiper lip 27 does not abut the surface 34 and therefore does not produce a wiping effect, the suction nozzle 6 remains however closed, so that no undesired bypass occurs at these points. The suction effect is therefore concentrated in the areas where cleaning fluid is effectively wiped off.
- the support surface 33 supports the wiper lip 27 essentially over its entire length, that is to say in particular also in a region which lies opposite the front edge 31. This makes it possible to press this front edge 31 despite the flexible design of the wiper lip 27 with precisely metered pressure against the surface 34 and thus to meter the wiping effect.
