Description

Device for dehumidifying a wet mop

The invention relates to a device for dehumidifying a wet mop, with a flat holder, on the underside of a mop cover is arranged with a Auspressvorrichtung designed as a Auspresswalze and an abutment having dehumidifier, the Auspresswalze and the abutment between them a passage gap for the holder and form the mop cover and are arranged and arranged so that they can squeeze the holder together with the mop cover between them for dehumidifying the mop cover.

From DE 39 13 698 A1 discloses a wide press for dewatering a spanned on a holder plate wet wiper bezugs known. There, the pressure roller connected to a frame and two spaced-apart pressure rollers form a spatially fixed Abpresskanal. In order to drain wipers in different dimensions, it is provided to change the position of the pressure rollers according to what the fastening means of the pressure rollers are designed releasably. However, this usually requires the use of tools and designed otherwise so expensive that an adjustment appears justified only when changing the wiper device.

In contrast, in the case of the device known from EP 0 609 187 A1, the respective pinch roller presses the dampener via a spring-loaded lever against the ejection roller. As a result, it is possible in a simpler manner to adjust the extrusion force and thus the desired residual moisture of the wet mop; The disadvantage, however, is that this two separate lever devices are necessary, which is not only technically complex, but also makes the separate adjustment to both levers in each case the same degree required.

The invention has for its object to improve a device of the type mentioned so that the degree of dehumidification of the wet mop can be adjusted reproducible in a simple manner. This object is achieved according to the invention in that the squeezing roller and / or the abutment against each other via a single adjusting member by hand or driven adjustable and defined to selectable distance values are fixedly adjustable.

The advantage achieved by the invention consists essentially in the fact that selectable dehumidification values can be preset in a simple and reproducible manner, wherein it is also possible by appropriate scaling of the setting member to be able to do so even when using wet wipers different in thickness.

In order to move the holder and the mop cover through the dehumidifying device, in a preferred embodiment of the invention, a drive may be provided which acts on the ejection roller and / or the counter bearing or can also operate independently.

It is further provided that the squeezing roller is arranged to rest on the mop cover and extends over the entire width of the mop cover, and that the abutment consists of two axially aligned printing elements axially form a gap between them. Thus, wet mops can be passed through the device having a handle attached to the handle, the handle passes through the gap formed by the two pressure elements.

Further, it is provided in the context of the invention that the squeezing roller and the counter bearing are formed by rollers which are rotatably supported by bearing or ball bearings on bearing shafts. Then there is the further possibility that the drive is designed as acting on the ejection roller and / or the abutment rotary drive, which can be dispensed with additional drive means.

In order to avoid the occurrence of higher forces during the passage of the wet mop by the dehumidifier, for example, should coarse parts adhere to the mop cover, which form a protruding thickening, the squeeze roller and / or the abutment from their set mutual distance position to increase the passage gap against a spring element be adjustable.

In a first advantageous embodiment of the invention, it is provided that the bearing shaft of the extrusion roller guided displaceably in the direction of the anvil and eccentric risch is arranged in a rotatable and lockable, designed as a cam and a fixed bearing block eccentric. By rotation of the eccentric, the bearing shaft is moved in their leadership to the anvil or away from it, which can be achieved by rotating the eccentric alone to influence the mutual distance position. For this purpose, the bearing shaft can be displaceably guided in oblong holes by bearing plates arranged at each end. In an alternative embodiment, however, the bearing shaft can also be mounted in slidably guided sliding blocks.

In order to make the adjustment of the distance between the squeezing roller and the anvil in a simple manner, a rotary knob for adjusting the width of the passage gap is rotatably connected to the eccentric coaxial with the bearing shaft of the squeezing roller. This knob can be provided with an appropriate labeling or scaling over which a simple and reproducible adjustment of the degree of dehumidification is possible.

In a second embodiment of the invention, the squeezing roller is arranged on a hinged pressure lever, which is adjustable via an adjusting member provided with a knob in its pivotal position. Again, the knob can be provided again with a comparable scale.

The adjusting member is advantageously formed at least in a partial region as a threaded rod and guided in a threaded bore of a bearing element fixed to the device.

The pressure lever is expediently designed as a two-armed lever, at one end of the Auspresswalze and at the other end of the adjusting member is pivotally connected.

In a third advantageous embodiment of the invention, however, the squeezing roller for adjusting the passage gap via an electromechanical actuator is adjustable. This opens up further possibilities, in particular can be made by suitable measures even a fully automatic adjustment, for example, to different thickness wet mop.

First, it is recommended that the electromechanical actuator in terms of the already provided in the device anyway electrical operation of electric motor or electromagnetically driven or designed as a memory metal with return spring. In an electromagnetic drive, it may be necessary to provide suitable pawls that fix the electromagnetically selected setting.

Advantageously, a force sensor can also be provided for determining the pressing force of the squeezing roller, the measured value of which can be displayed on a display. Additionally or alternatively, however, there is also the possibility that this measured value is used directly for actuating the electromechanical actuator. Here, too, it is possible to deduce the degree of moisture from the determined force by means of a suitable conversion, so that ultimately a regulation to fixed values of the degree of moisture is possible in this way.

The force sensor can be formed, for example, by a strain gage arranged on the spring element or on the lever.

However, there is also the possibility that the force sensor is formed by a piezoelectric element arranged on the bearing of the extrusion roller or of the counter bearing.

In a further development of the invention, the device may also have a memory element which is provided for storage and for retrieving preferred distance values. In addition, tables can be stored in this memory, which allow an assignment of measured pressure force to the desired residual moisture.

Finally, it is still possible to directly provide a sensor for determining the residual moisture of the mop cover. This can be done by conventional humidity sensors; However, other measuring methods are conceivable, for example a conductivity measurement over the length of the mop cover.

In the following the invention will be explained in more detail in an embodiment shown in the drawing. Show it

1 is a schematic side view of a device for dehumidifying a wet mop together with a wet mop for use with the device as an embodiment, 2 is an enlarged partial view of the device of FIG. 1 from the front together with the wet mop,

3 shows a side view of the device according to FIG. 1 during operation of the device for moistening and wetting the wet mop, FIG.

Fig. 4 is a schematic detail of the dehumidifier, in the partial figure a) in side view and in the partial figure b) in cross-section and

Fig. 5 shows an alternative embodiment in one of Fig. 4a corresponding representation.

In FIG. 1, a manually operated device 104 for moistening a wet wiper 101 is shown schematically as an exemplary embodiment. The wet mop 101 has a holder 102 attached to a handle 118 for holding a mop cover 103. The mop cover 103 is flexible and absorbent, so that it can be moistened to clean particular floors with a cleaning liquid.

For moistening, the wet wiper 101 is guided in the direction of the arrow by the device 104 through a guide 113, which has individual guide elements in the form of horizontally arranged sheets. The guide 113 guides the holder 102 in a horizontal position along a horizontal trajectory over a nozzle 112. The nozzle 112 is connected via a fluid line 11 to a pump 108 located at the bottom of a container 105 which forms the base of the device 104. In the container 105 is a cleaning liquid 106, which can be sucked by the pump 108 via an input filter 107 and pumped through line 11 to the nozzle 112. Through the nozzle 112, the liquid 106 can be injected from below against the mop cover 103 of the wet mop 101.

In the guide 113, a sensor 114 is provided, for example in the form of a switch, which detects the presence of the holder 102 in the guide 113. Once the holder 102 has been inserted into the guide 113 and this has been detected by the sensor 114, a controller, not shown, controls the pump 108, so that the liquid 106 is sprayed upwardly through the nozzle 112. At the same time a motor-driven drive roller 110 is driven, which is arranged below the movement path. On the drive roller 110 opposite side of the movement path are two counter-rollers 109 are arranged, which are arranged coaxially with each other and are rotatable about an axis of rotation which is parallel to the axis of rotation of the drive roller 110. The holder 102 can thus be pulled together with the mop cover 103 between the drive roller 110 and the counter rollers 109 therethrough.

The distance between the drive roller 110 and the counter rollers 109 is dimensioned so that the holder 102 with the mop cover 103 is in frictional engagement with the rollers 109, 110, so that it can be detected and driven.

The drive roller 110 extends over the entire width of the mop cover 103 perpendicular to the drive direction, so that it rests on the bottom of the mop cover 103 over the entire width. The two counter rollers 109 are each arranged so that they are arranged over the edges of the holder 102 and the mop cover 103 in width extension of the holder 102 and leave a gap between them open. The space between the rollers 109 serves to pass the handle 118 of the wet mop.

In Figure 2, the upper part of the device 104 is shown together with the lower part of the wet mop 101 from the front. In this illustration, it can be seen that the counter rollers 109 each consist of two cylinder sections 119, 120 which are arranged concentrically with respect to one another and which have different diameters. The smaller cylinder portions 119 are respectively disposed inside and the larger cylinder portions 120 each outside. As a result, the gap between the drive roller 110 and the larger cylinder portions 120 is smaller on the outside than between the drive roller

110 and the smaller cylinder portions 119. The drive roller 110 is further connected to drive in the direction of rotation with a motor 116.

Furthermore, it can be seen in FIG. 2 that the mop cover 103 is wider in the direction of movement than the holder 102 and projects beyond the sides of the holder 102. The protruding on both sides edges of the mop cover 103 thereby form a cushion for the holder 102, which also serves as protection against damage to other objects such as furniture in particular by the holder 102. Since the holder 102 must be able to transmit force for squeezing the mop cover 103, the holder 102 is preferably made of a rigid material such as a metal, so that the holder 102 is quite different Could damage objects in contact. For this reason, a protruding, cushioning mop cover 103 is particularly advantageous as a protection.

In order to be able to extrude the protruding parts of the mop cover 103, the smaller cylinder portions 119 are internally sized so that they can press out the holder 102 together with the underlying part of the mop cover 103 on the drive roller 110, and the larger cylinder portions 120 are sized in that they can press out the edges of the mop cover 103 on the drive roller 110 projecting laterally beyond the holder 102. For this purpose, the height of the larger cylinder sections 120 in the axial direction is at least equal to the width of the protruding edge of the mop cover 103 and the diameter of the larger cylinder sections 120 together with the distance of the axes for the counter rollers 109 and the drive roller 110 is selected so that the protruding edge of Mop cover 103 can be compressed in between.

With the smaller cylindrical portions 119 arranged inside, it is only necessary that they rest on the holder 102 and be able to press it against the drive roller 110 in order to be able to squeeze out the part of the mop cover 103 covered by the holder 102. There is a gap between the two smaller cylindrical portions 119 for passage of the stem 118. The narrower the gap, the more difficult is the passage of the stem 118. Conversely, as the gap narrows, the area with which the smaller cylindrical portions increase 119 on the holder 102, and thus reduce the bending moments acting on the holder 102.

The two adjoining cylinder sections 119, 120 are mounted coaxially with one another on a common shaft, wherein both cylinder sections 119, 120 can rotate independently of one another.

By acting over the entire width pressure of the drive roller 110 of the mop cover 103 is dehumidified again in part or it is pressed liquid out of the mop cover 103. The pushed-out liquid 106 runs on an intermediate bottom 117 and from there through a dirt filter 115 back into the container 105. When passing the wet mop 101 through the guide 113, as shown in Figure 3, thus the mop cover 103 from below with the cleaning liquid 106 sprayed, so that the mop cover 103 humidifies and dirt thereon ausge- can be flushed, and then partially dehumidified again so that it exits on the right side of the device 104 with a defined humidity. This causes the mop cover 103 does not drip when cleaning. The controller also detects when the holder 102 releases the sensor 114 again or when the rear end of the holder 102 has passed the sensor 114 and then controls the pump 108 and the drive roller 110 for a certain period of time until the holder 102 is complete through the rollers 109, 110 has been pulled through. The control of the pump 108 can also be terminated before the actuation of the rollers 109, 110.

In order to be able to adjust the degree of dehumidifying of the wet mop in a simple manner, the squeezing roller 110 can be adjusted by hand against the counterbearing 109 by means of a single adjusting member 124 and can be fixedly set to selectable distance values. Thus, selectable dehumidification values can be predefined in a simple and reproducible manner, whereby in a manner not shown in detail in the drawing by appropriate scaling of the setting member 124, this is also possible when using wet wipers 101 which are different in thickness.

In order to avoid the occurrence of higher forces during the passage of the wet mop 101 through the dehumidifier, for example, if rough parts should adhere to the mop cover 103, which form a protruding thickening, the squeezing roller 110 is adjustable from its set mutual distance position to increase the passage gap against a spring element 125 ,

In the embodiment of FIG. 4, the bearing shaft of the extrusion roller 110 is displaceably guided in the direction of the abutment 109 and arranged eccentrically in a rotatable and lockable, formed as a cam and a fixed bearing block 126 eccentric 127. By rotation of the eccentric 127, the bearing shaft is moved in its direction to the abutment 109 towards or away from it, whereby an influence of the mutual distance position can be achieved only by turning the eccentric 127. For this purpose, the bearing shaft is displaceably guided in oblong holes 128 by bearing plates 129 arranged at the end. In an alternative embodiment, not shown in the drawing, however, the bearing shaft may be mounted in slidably guided sliding blocks. In order to make the adjustment of the distance between the Auspresswalze 110 and the anvil 109 in a simple manner, coaxial with the bearing shaft of the Auspresswalze 110 is an adjusting member 124 forming rotary knob for adjusting the width of the passage gap rotatably connected to the eccentric 127. This knob can be provided with an appropriate labeling or scaling over which a simple and reproducible adjustment of the degree of dehumidification is possible.

In the embodiment according to FIG. 5, the squeezing roller 110 is arranged on a hinged pressure lever 130, which is adjustable via the adjustment member 124, which in turn is provided with a rotary knob. Again, the knob can be provided again with a comparable scale.

The adjusting member 124 in this case has, at least in a partial region, a threaded rod 131, which is guided in a threaded bore of a bearing element 132 fixed to the device. The pressure lever 130 is in this case designed as a two-armed lever, at one end of the Auspresswalze 110 and at the other end of the adjusting member 124 is pivotally connected.

The adjustment of the Auspresswalze 110 to change the passage gap but can also be done via an electromechanical actuator. This opens up further possibilities, whereby by suitable measures even a fully automatic adaptation of the device, for example, to differently thick dampener 101 can be made.

The electromechanical actuator is electromotively or electromagnetically driven in view of the device provided anyway in the electrical operating mode. But it can also be designed as a memory metal with return spring. In an electromagnetic drive, it may be necessary to provide suitable pawls that fix the electromagnetically selected setting.

To determine the pressing force of the extrusion roller 110, a force sensor is then provided, the measured value of which can be displayed on a display. However, this measured value can also be used directly for actuating the electromechanical actuator. In addition to the possibility of an automatic adjustment of the device to different thicknesses wet wiper 101 can also be determined from the determined force on a suitable Conversion to the degree of humidity can be closed. In this way, finally, even a regulation to fixed values of the degree of humidity is possible.

The force sensor can be formed in a conventional manner by a strain gage arranged on the spring element or on the lever or by a piezoelectric element arranged on the bearing of the squeeze roller or of the thrust bearing.

In the manner not further illustrated in the drawing, the device may also comprise a memory element which allows the storage as well as the retrieval of preferred distance values. In addition, tables can also be stored in this memory, which allow an assignment of measured pressure force to the desired residual moisture.

Another possibility for determining the residual moisture of the mop cover 103 is obtained by using a sensor. This can either be designed as a conventional humidity sensor; However, other measuring methods, such as, for example, a conductivity measurement over the length of the mop cover 103, are also conceivable.
