Description

The invention relates to a device for moistening and dehumidifying at least one wiping part of a wet mop, with a drive device which can move the wiping part and at least one moistening device for moistening the wiping member with a liquid relative to each other, and moving past the moistening device sections of the wiping member and a dehumidifier relative can move to each other, wherein the moistening device is at least one spray nozzle, which can be supplied by a pump with liquid.

Such a device is apparent from the DE 22 27 554 A1 or parallel to it FR 21 87 266 A ,

The term wet wiper refers to all the cleaning devices which have an absorbent wiping part which can be impregnated with a cleaning liquid and passed over the surfaces or objects to be cleaned in the moist state. As a cleaning liquid, water is generally used with additives if necessary. Known embodiments of wet mops are, for example, mops and wiping pads, which have a fringed or flat wiping part, which is attached to the end of a stem. Usually such dampers are used together with a container for receiving the cleaning liquid, wherein the container usually has a manual dehumidifier, with which the wiping part can be pressed or wrung out. For cleaning, the wet mop is usually dipped with its wiping part for moistening in the cleaning liquid, partially dehumidified to achieve a certain for cleaning optimum humidity, and passed over the object to be cleaned. Subsequently, the wiping member is usually dipped in the cleaning liquid to rinse the dirt received, wherein the wiping member is moistened again. These activities are repeated very often during cleaning.

Disadvantageously, manual dehumidification requires a great deal of effort and, due to the never equal use of force by the operator, provides uneven dehumidification values. Furthermore, the container must be at least as large as the wiping part to allow its complete humidification by immersion, so that the container has a high weight together with the necessary amount of liquid for its sufficient filling amount. By washing out the wiping part in the liquid, it becomes increasingly soiled during cleaning, so that the wiping part moistened in it also becomes dirty. In order to prevent the wiping part from being excessively soiled before wiping in order to achieve a satisfactory cleaning effect, the liquid must be changed frequently.

The invention has for its object to provide a generic device for moistening and dehumidifying a wiper part of a wet mop, with an improved cleaning effect of the wet mop is achieved with a reduced amount of liquid.

According to the invention, this object is achieved by the features specified in patent claim 1. Advantageous developments of the invention will become apparent from the dependent claims.

By using a moistening device for moistening the wiping part, the amount of liquid to be kept is reduced, since in the least case, this only has to be sufficient for a complete moistening of the wiping part. By the subsequent dehumidification a defined humidity is achieved with a high repeatability, this being advantageously achieved in one operation. Since the wiper part has to be dehumidified and dehumidified very often during cleaning, a lot of time can be saved by performing these activities in one operation.

It is also conceivable that the moistening and dehumidifying done in a single device. For example, for this purpose, the wiping part can be guided over rollers which have openings on their surface from which the liquid emerges. The rollers can furthermore have a structured surface or bristles, with which the wiping part can be mechanically deformed, at least on its surface, and thus dirt which is stuck in it can be better removed.

If the wiping part remains fixed in relation to the device and the humidifying and dehumidifying device are moved relative to the device and the wiping part, a simple stop can be provided for fixing the wiping part, to which the humidifying and dehumidifying device is moved. A more complex fixation can thus be avoided, since forces act on the wiper part in this case only in one direction.

According to the invention, the moistening device is a spray nozzle which is supplied with fluid by a pump. This embodiment can be realized with little effort, with a directed to the wiping liquid jet high cleaning effect can be achieved.

In the solution according to the invention, it is also possible to selectively collect the dirt received by the wiping part in a filter by passing the liquid removed from the dehumidifying device to the wiping part, which contains the dirt absorbed by the ground, through a filter and so the dirt is collected. In this way can be cleaned with a certain amount of liquid a much larger area, since the recorded dirt is continuously collected and separated.

If the spray nozzle is set up so that it sprays harder at the edges or has a higher and / or stronger liquid ejection there, the edge areas of the wiper part can be cleaned better. In this way, just the edges that absorb dirt when using the wiper part, can be cleaned more intensively. This is particularly advantageous when the wiping member is passed through the device for wetting and dehumidifying transversely to its wiping direction.

In order to moisten or rinse the wiping part over its entire width, several juxtaposed and directed against the wiping nozzle nozzles can be used. Another possibility is to provide at least one nozzle whose jet is directed onto a deflection surface, which fans out the jet and directs it against the wiping part.

When using a wiping part which has a shape deviating from the rectangular shape, the moistening device extending over at least part of the width of the wiping part should at least approximately correspond in its position or shape to the leading edge or contour of the wiping part.

When using a wiping member, which has, for example, a parallelogram or a diamond shape, it is expedient to extend the moistening device across the width of the wiping member in a direction which deviates from the direction perpendicular to the drive direction of the wiping member by an angular amount. Ideally, the angle of the orientation of the moistening device corresponds to the included angle between the transverse side and the right angle to the longitudinal side of the wiping part.

If a wiping part is brought to a moistening device which extends perpendicular to the drive direction of the wiping part, cleaning solution may be sprayed out. In addition to the angled orientation of the moistening device, a splash guard, for example in the form of rubber lips, can also be provided on the housing side to avoid spillage. If the nozzles of the moistening device are designed to be pivotable, this measure can also help to avoid squirting out of cleaning liquid. When the wiper part is inserted into the cleaning device, the nozzles of the wetting device are pivoted in the direction of the interior of the housing so that the cleaning fluid jet is directed away from the inlet opening for the wiping part.

The cleaning effect of the spray nozzle on the wiping part can be enhanced if the spray nozzle or the deflection surface is pivoted back and forth during the moistening. In this way, the angle of incidence of the liquid jet is constantly changing, so that the mechanical action and thus the cleaning of the wiping part can be enhanced, in particular in the case of a wiping part with movable fringes or fibers. A stronger mechanical action on the surface of the wiper member can also be achieved by at least two controllable spray nozzles are provided, the liquid jets impinge on the wiper member at different angles and / or at different locations, and these spray nozzles are driven in alternation. The higher mechanics entry improves the cleaning of the wiper part.

The dehumidification of the wiping part by pressing together between opposite rollers has the particular advantage that rollers can be stored in a particularly simple and robust manner. Furthermore, the rollers can be used in addition to the drive of the wiping member in the longitudinal direction, which can advantageously be driven rollers with a cost-effective rotary motor. In this case, in addition to a driven pair of rollers, in which the wiping part is already partially dehumidified, further, possibly non-driven roller pairs may be arranged to squeeze the further liquid from the wiping part. Advantageously, the roller or rollers are driven, on which or the wiping part comes to rest. The opposite rollers are advantageously interrupted in the middle by a gap through which a stem of the wet mop can be performed to hold the wiper member.

It is also possible to provide the wiping part or a support plate for the wiping part with a toothing, in which engage a drive device and drive the wiping part can move through opposite rollers for dehumidification.

The device according to the invention can also be used in wet mops with two wiping parts, for example in a flat wiping pad, in which a wiping part is arranged on both sides. In this case, both humidifier and dehumidifier can be designed on both sides, so that both sides of the wiper pad can be humidified and dehumidified at the same time. Thus, for example, for moistening two parallel sprayers directed against each other and for dehumidifying two parallel rollers may be provided, which are preferably arranged vertically, wherein the opposing spray devices and rollers form a gap open on one side through which the wiper pad can be passed.

In an advantageous embodiment, the device for moistening and dehumidifying a container for the liquid, but all components of the device are connected to each other with this container and can be separated from the container together. For example, the container may have the shape of a conventional bucket, the remaining components can be used as a technology block in the container, which may have inside fastening means, which engages the technology block during insertion. To this In this way, the container can be cleaned particularly easily by first removing the remaining components.

The activation of the moistening or dehumidifying device can be done in various ways. For example, a switch may be provided in the region of the spray nozzle, which is responsive to the insertion of the wiping part and simultaneously controls the moistening and dehumidifying device. In this case, a follower control is expediently provided, so that the drive device continues to move the wiping part for a while in order to move it completely through the dehumidifying device when the wiping part has moved past the switch. This type of control is useful when the humidifier and dehumidifier are powered by a single motor. It can also be provided that after the switch is no longer activated by the wiping part, the moistening device remains activated for a shorter time than the drive device, since the rear end of the wiping part passes the moistening device earlier than the dehumidifying device or drive device, if both in a device happens, as is the case when driving and squeezing between two roles.

When using a wiping part which has a shape deviating from the rectangular shape, such as a parallelogram or diamond shape, after leaving the wiping part of the nozzle area, the dehumidifier must be operated even further, on the one hand to the end of the wiper part which is located before the dehumidifier on the To dehumidify preset residual moisture and on the other hand to transport the wiping part completely out of the dehumidifying device. For this purpose, two switches are provided, wherein the one switch detects the entry of the wiper part in the device and the other switch recognizes the emergence of the wiper part of the device. For a given transport speed, the motor and the pump can be controlled in such a way that it is ensured that the wiping part can be cleaned on the entire surface and that a spray-out of cleaning liquid is prevented. If the wiping part has a parallelogram-shaped contour, the moistening device preferably extends at an acute angle to the direction perpendicular to the drive direction of the wiping part, so that its orientation corresponds to the leading edge or contour of the wiping part.

If the humidifying and dehumidifying device can be controlled separately, two switches can be provided, which are responsive to the wiping part and of which is arranged for driving the humidifying device in a region detectable by the humidifying device and the switch for driving the drive device is arranged in a region, in which the wiping part can be detected by the drive device.

For the separate control of moistening device and dehumidifying device, the line can also be provided with a controllable valve which supplies the moistening device with liquid. In this case, it is possible to drive the pump for supplying the moistening device or the spray nozzle and the drive device with a single motor and still control the spray nozzle separately.

The drive device can furthermore also be reversible, so that it can move the wiping part in both directions. In this case, in each case a switch may be provided in front of or behind the drive device, which controls the drive device in such a way that the wiping part is drawn in and moved to the other side, regardless of which side it has been inserted from. In this case, the moistening device or spray nozzle can be designed to be controllable and controlled in such a way that it moistens the wiping part only when it is introduced from the side on which the moistening device lies in front of the dehumidifying device. In this way, it is possible to dehumidify the wiper part without moistening, in which it is introduced from a certain side, for example, if a lower humidity of the wiper part is desired. This may be the case during dry wiping of a cleaned soil.

The splash guard for the device for moistening advantageously has a slot through which a handle of the wet mop can be passed. To prevent it from splashing out through this slot, a seal of flexible material may be disposed within the slot. The seal may for example consist of two in particular overlapping rubber lips or rows of bristles.

If only one motor is to be used for operating the dehumidifying device and the pump for the moistening device, it must be prevented at least when leaving the wiping part of the device that cleaning solution can spray out of the device. If, on the other hand, it is to be ensured that the wiping part can be cleaned with maximum nozzle action right at the beginning of insertion into the device, then a flap can be provided at the inlet into the device and optionally also at the exit from the device. The flap is preferably pivotally mounted. The flap is mounted over the nozzle assembly. The flap may be mechanically biased against a closed position via an elastic lever or spring mechanism. The flap is pivoted by the insertion of the wiper member in an open position. The actuation of the flap may be performed by a switch, preferably the already existing switches for controlling the dehumidifying device and pump of the moistening device, and following functions such as e.g. the start of the rollers of the dehumidifier or the start of the pump of the humidifier can be activated.

It would be disadvantageous if, after cleaning the wiping part, residues of cleaning liquid would still remain on the upper side of the wiping part, since these residues can reach already cleaned bottom surfaces during the following wiping process. This is undesirable because the wiping result is adversely affected and moisture-sensitive floors could be damaged.

To remedy this disadvantage, the nozzle arrangement can be adjusted so that cleaning liquid is not sprayed over the edge of the wiping part away. However, it must be accepted that the immediate edge area of the wiper part is not completely washed out. However, the washing out of Randbereicht is important because it collects most of the dirt there. However, if the nozzle assembly is adjusted so that even the immediate edge region of the wiper member is completely washed out, cleaning solution could reach the top of the wiper member. In order to avoid this, sealing surfaces can be provided in the device, which bear against the longitudinal sides of the wiping part inserted into the device and thereby prevent a passing of cleaning liquid from the underside of the wiping part to the top of the wiping part.

The sealing surfaces may be designed as elastically deformable plates, e.g. be formed of plastic or foam. As a foam, a closed-cell foam can be used in an advantageous manner. The width of the sealing surfaces is adapted to the wiping part, so that no cleaning solution can reach the top of the wiper part directly or indirectly. If such sealing surfaces provided, can be cleaned with increased nozzle pressure and cleaning performance can be increased. In particular, the edge can be cleaned with higher nozzle pressure, which is better cleaned just the more contaminated edge region of the wiper part. The sealing surfaces may be resiliently biased against the longitudinal sides of the inserted into the device wiper.

Regardless of the use of sealing surfaces, the cleaning effect can be enhanced if a nozzle arrangement is selected, with which it is possible to work with higher pressure in the edge area of the wiping part and only a lower pressure is provided in the middle area of the wiping part. The different pressure exerted on the wiper part nozzles can either have different opening cross-section or be supplied via separate pumps that produce different fluid pressure.

In Fig. 1 a wet mop 1 is shown in the form of a wiper pad, in which at the bottom of a partially illustrated stem a support plate 2 is hinged, which in turn has on its underside an absorbent wiper part 3. The wiping part 3 is made of a textile material.

Furthermore, in Fig. 1 an embodiment of a device 4 according to the invention for moistening or dehumidifying the wiping part 3 shown. The device 4 has a container 5 for receiving a cleaning liquid 6. Above the container 5 is closed by an intermediate bottom 17, to which the other components required for loading and dehumidifying are attached and which can be taken out of the container 5 together with these components.

Above the intermediate floor 17, a drive device is arranged, which consists of opposite rollers 9, 10, of which the lower roller 10 can be driven by a motor 16. The wiping part 3 can be detected by the roller 10 together with the carrier plate 2 and moved in the longitudinal direction of the wiping part 3. The distance between the rollers 9, 10 is dimensioned so that the wiping member 3 is pressed together while passing through it, while the liquid 6 contained therein is pressed out. In order to improve the Auspresswirkung and to move the wiping part 3 safely, the roller 10 has an elastic coating. In front of and behind the drive and dehumidifying device formed from the rollers 9, 10, guides 13 are arranged, which guide the carrier plate 2 and the wiping part 3 during insertion and when passing through the dehumidifying device 9, 10.

In Fig. 1 To the left of the dehumidifying device 9, 10, a moistening device in the form of a slot nozzle 12 is arranged. The slit nozzle 12 is supplied by a submersible pump 8 with liquid 6 via a hose 11. The inlet of the pump 8 is with a Provided inlet filter 7 and is disposed near the bottom of the container 5. The pump 8 is firmly connected to the intermediate bottom 17 and can be removed together with this from the container 5.

The intermediate bottom 17 further has a removable coarse filter 15 through which liquid 6, which has been pressed out of the wiping part 3 above the intermediate bottom 17 by the dehumidifying device 9, 10, can flow into the container 5.

In the insertion area for the wiping part 3, a switch 14 is further arranged, which is activated upon insertion of the carrier plate 2 and the wiping part 3.

In Fig. 2 the drive device is shown from the side. The lower roller 10 extends over the entire width of the wiper part 3 and is mounted on the sides of vertical supports which are fixedly connected to the intermediate bottom 17. The motor 16 for driving the roller 10 is also attached via a carrier to the intermediate bottom 17. Above the two end portions of the roller 10, a roller 9 is mounted in each case, wherein between the rollers 9 is sufficient distance to pass the stem of the wet mop 1 can. The rollers 9 press from above against the support plate 2, which in turn presses the wiping member 3 against the roller 10. In this way, the wiping member 3 can be simultaneously passed through and dehumidified.

In Fig. 3 the device for humidifying and dehumidifying is shown in operation. For this purpose, the support plate 2 is inserted together with the wiping part 3 in the left guides 13, whereby the switch 14 is actuated. The switch 14 then controls the motor 16 which rotates the roller 10 and drives the pump 8. If the wet mop 1 is now guided further in, the wiping part 3 is first guided over the spray nozzle 12 and then into the dehumidifying device 9, 10. By the liquid jet emerging from the spray nozzle 12, the wiping member 3 is moistened and optionally rinsed out adhering thereto dirt. As soon as the wiping part 3 passes between the rollers 9, 10, it is detected by the driven roller 10 and moved on in the image to the right. In this case, the wiping part 3 is pressed together between the rollers 9, 10 and in this way at least partially dehumidified. The emerging during pressing liquid 6 flows on the intermediate bottom 17 to the filter 15 and therethrough back into the container 5. In this case, the dirt contained in the liquid 6 in the filter 15 withheld. The filter 15 is removable from the outside, so that it can be removed if necessary, removed from dirt and reused. A controller, not shown, is set up so that after the activation of the switch 14 by the wiping part 3, the motor 16 remains actuated for a while, in order to move the wiping part 3 completely through the dehumidifying device 9, 10. In this case, it is also possible to provide a plurality of switches 14, which are in particular spaced apart from one another, wherein all switches for activating the device 4 must be activated. Thus, the safety of the device can be increased and prevented, the device 4 is inadvertently put into operation by other objects that can not address all the switches 14 are pushed simultaneously.

This rinsing and dehumidifying process can often be repeated if, for example, dirt still adheres to the wiper part 3. The residual moisture in the wiping part 3 achieved with the dehumidifying device 9, 10 can be adjusted by influencing the force with which the wiping part is pressed together. This can be done for example by the application of the roller 10 and / or opposite rollers 9 with a spring force. Advantageously, the continuous roller 10 is resiliently mounted at the ends, since in this case the storage must absorb much lower torques and therefore can be realized with less effort. It is also conceivable, however, to store both the roller 10 and the opposite rollers 9 resiliently.

Another way to adjust the force with which the wiping member 3 is compressed, is to adjust the distance between the opposite rollers 9, 10. Since the wiping member 3 is compressible, the pressing force can be changed with the roller spacing. This change in the pressing force by changing the distance is also achieved by an elastic coating on the roll 10 rolling on the wiping part 3, in which case the wiping part 3 does not necessarily have to be compressible, so that even very thin wiping parts 3 can be used.

Furthermore, the device 4 may have a device for detecting the filling level of the container 5. The level can be displayed to the outside, so that an operator can inform himself about the level, in addition to Unteroder Exceeding limit values, an optical and / or acoustic signal can be emitted. Furthermore, the detected level in the control of the device 4 can be taken into account, for example, by operating at too low or too high level is prevented or the pump 8 is operated at low level with lower power in order not to lower the level in operation so far.

In Fig. 4 the orientation of the moistening device 12 with respect to the dehumidifying device 10 is shown. The position of the dehumidifier 10 corresponds to the drive direction for the wiping part 3 of the wet mop 1. In the example shown, the orientation α transverse to the drive direction of the wiper part 3 corresponds to the angle at the wiping part 3 is enclosed by the transverse side and the right angle to the longitudinal extent of the wiper part ,

In Fig. 5 two switches 14a and 14b are shown, which serve to drive motor 18 and pump 19. A respective switch 14a, 14b is arranged before or after the dehumidifying device 9, 10. Between dehumidifier 9, 10 and the switch 14b, the moistening device 12 is arranged.

In Fig. 6 the pivotable flap 20 is shown, which is pivotable about a pivot 21. The flap 20 is biased by a spring mechanism 22 elastically against the closed position. The front edge 23 of the wiper member actuates the flap 20, which is coupled via a lever 24 to the switch 14. In the illustrated position, the flap 20 is already almost completely open and the switch 14 just to be actuated. The switch 14 is already actuated when the flap 20 is not fully opened and the wiping part 3 is not yet detected by the driving device 9,10, so that the follow-up functions can start in time.

In Figure 7 the two variants of a sealing surface 25, 26 are shown, which rest against the longitudinal sides of the wiping part 3 introduced into the device. The sealing surface 25 is formed as an elastic plastic part. The resilient bias of the sealing surface 25 takes place due to the elasticity of the plastic material. The sealing surface 26 is formed as a closed-cell foam part. The resilient bias of the sealing surface 26 is due to the elasticity of the foam material. Have the provided sealing surfaces 25, 26 do not have the necessary elasticity to a resilient To ensure bias, for example, a separate spiral spring can be provided, which biases the sealing surfaces 25,26 resiliently against the edge of the wiper member 3.
