Abstract

The mop has a flat holder and a mop covering attached to the underside of the holder and projecting from an edge of the holder with an edge protection border. The mop can be wrung in a corresponding device. The wringing device has a first pressing element and a second pressing element, which traverse the holder with the mop covering and which squeeze the mop cover in order to wring it. One of the pressing elements continuously extends over the entire width of the mop covering perpendicular to the direction of movement of the holder. The other pressing element has two parts with a gap in between for allowing the passage of a handle joined to the holder. In the vicinity of the gap formed by the pressing element, the edge protection border is formed so that it does not absorb and dirt and/or moisture.

Description

The invention relates to a wet mop with a flat holder and a fixed to the underside of the holder, the edge of the holder with an edge protection edge superior mop cover, which is designed so that it can be dehumidified in a device provided for this purpose, to a dehumidifier with a first pressure element and a second pressure element, which passes through the holder with the mop cover and which compress the mop cover for dehumidification, wherein one of the pressure elements extends continuously over the entire width of the mop cover perpendicular to the direction of movement of the holder, while the other pressure element comprises two parts, between which there is a gap enabling the passage of a handle connected to the holder, transverse to the direction of movement.

Out WO 2004/049884 A2 is a wet mop and an associated device for cleaning and dehumidifying known, the wet mop is provided on both its longitudinal sides with a protruding mop cover. This projection of the mop cover serves to prevent direct contact between the usually made of hard material, for example, aluminum holder with furniture and other furnishings to avoid damage to these. This is in the WO 2004/049894 A2 Also complementary already known edge protection in the form of a rubber edge attached to the narrow side.

Finally, that describes DE 102 56 091 A1 an autonomous wet cleaning device, which is provided only on the broadside with a protruding mop cover, while on the narrow side a soft surface is provided as edge protection.

In view of the most comprehensive edge protection, it would be desirable to make the mop cover survive on the narrow side. Because of the existing for the passage of the stem gap in one of the two printing elements but then no dehumidification occurs in the region of this gap.

The invention has for its object to provide the wet mop of the type mentioned in a particularly simple manner both on the broad side as well as on the narrow side with an acting as edge protection supernatant of the mop cover, it being ensured that after cleaning and dehumidifying the wet mop especially in the area of the gap no residual contamination or undesirable high residual moisture is present.

This object is achieved according to the invention in that the edge protection edge in the region of the gap formed by the two-part pressure element is designed so that it can not absorb dirt and / or moisture.

The advantage achieved by the invention consists essentially in that can be wiped by the excess mop cover on the narrow side for a randnah also with the narrow side along furniture edges and other furnishings without touching it with the holder. In particular, this results in a much simpler designed structure, since no separate rubber edge or the like is required. The mop cover can be cleaned and dehumidified without modification in the already known cleaning and dehumidifying stations.

According to a first advantageous embodiment of the invention, the edge protection edge in the region of the gap on a recess formed by a recess. This recess affects neither the cleaning performance of the mop cover nor the desired effectiveness of the edge protection noticeable, since the gap is small compared to the narrow side of the holder.

According to a further embodiment of the invention, the edge protection edge is provided in the region of the gap with dirt and moisture-repellent coating. This variant thus has a full edge protection, while only the cleaning performance is minimized due to the dirt and moisture-repellent coating.

Another possibility is proposed in the context of the invention that the edge protection edge is formed in the gap of a sufficiently soft set material that is either dirt or moisture repellent itself or provided with dirt or moisture repellent substance. This design also ensures complete, all-around edge protection.

In order to ensure when cleaning and dehumidifying the wet mop in a corresponding wet cleaning device that the edge existing supernatant safely and smoothly enters the dehumidifier, it is recommended that a stiffener is provided for stiffening the edge protection edge. This stabilizing agent can basically consist of any material suitable for this purpose. In a particularly simple and therefore within the scope of the invention preferred embodiment, it is provided that protrudes as a stabilizer provided for a Velcro connection between mop cover and holder on the mop cover Velcro into the edge protection edge inside. By using the already required because of the attachment Flauschches can thus be dispensed with the use of additional materials.

Fig. 6

an alternative embodiment of the wet mop in the illustration according to Fig. 4 ,

In FIG. 1 is schematically illustrated as an embodiment of a device 104 for wetting a wet mop 101, which is operated manually. The wet mop 101 has a holder 102 fixed to a handle 118 for holding a mop cover 103. The mop cover 103 is flexible and absorbent, so that it can be moistened for cleaning in 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 leads the holder 102 horizontally along a horizontal trajectory over a nozzle 112 of time. 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 two counter-rollers 109 are arranged, which are arranged coaxially to 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 FIG. 2 the upper part of the device 104 is shown from the front together with the lower part of the wet mop 101. 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 inside and the larger cylinder portions 120 are disposed outside, respectively. 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 a motor 116 for driving in the direction of rotation.

Furthermore, in FIG. 2 to see that the mop cover 103 is wider in the direction of movement than the holder 102 and protrudes on the sides of the holder 102. The protruding edges on both sides 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 in particular of furniture 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 may well damage other objects in contact. For this reason, a protruding mop cover 103 is particularly advantageous as 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. Between the two smaller cylinder portions 119, a break or gap for passing the handle 118 is provided. The narrower the gap, the more difficult it is to pass the handle 118. Conversely, as the narrowing gap becomes narrower, the area at which the smaller cylinder sections 119 press against the holder 102 increases, thus reducing the bending moments on the holder 102 Act.

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 extruded 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 FIG FIG. 3 is shown, the mop cover 103 is thus sprayed from below with the cleaning liquid 106, so that the mop cover 103 moistened and dirt therein can be flushed out, and then dehumidified again in part, so that he on the right side of the device 104 with a defined Moisture leaks. This causes the mop cover 103 does not drip when cleaning. The controller detects this Also, 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 completely 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.

As already explained above, the protrusion of the mop cover 103 present on the longitudinal or broad side of the holder 102 is also dehumidified by the arrangement described. The attached to the narrow side of the wet mop 101 supernatant, however, is in the area of the

Passage of the stem 118 enabling gap is not dehumidified because there - in contrast to the area in which the inherently stiff holder 102 is present - no pressure on the supernatant is exerted. In FIG. 4 Therefore, a solution according to the prior art is shown, in which on the narrow side of the wet mop 101, only a soft edge 126 is provided rubber or plastic.

In order to provide a supernatant on the narrow side of the wet mop 101, but to prevent that in the gap, the left of the Fig. 5c again indicated by lines, an undesirably higher residual moisture than in the remaining mop cover 103 remains, the edge protection edge 124 in the area formed by the one pressure element 109 gap is designed so that it can not absorb dirt and / or moisture.

This can be done first by an embodiment, the one formed by an incision, in FIG. 6a on the right edge of the wet mop 101 indicated recess 125, which is located in the region of the gap. Since this gap is small in comparison to the narrow side of the holder 102, the recess significantly affects neither the cleaning performance of the mop cover 103 nor the desired effectiveness of the edge protection.

The edge protection edge 124 may in the gap but also - as out Fig. 5 such as Fig. 6c and 6d to see - be provided with a dirt and moisture-repellent coating 126, which also dehumidification is unnecessary in this area.

The edge protection edge 124 may according to Fig. 6 Finally, in the region of the gap also be formed by a sufficiently soft material 127, which is either itself dirt and moisture repellent, or provided with dirt and moisture repellent substance. This is schematic in the FIGS. 6c and 6d played.

In order to allow the supernatant of the mop cover 103 to run smoothly through the pressure elements 109, 110, when the mop cover 103 is pulled into the squeezing device, stiffening of the edge protection edge 124 is recommended by a stabilizing agent, which basically consists of any suitable material, for example a strip-like shape in the region of the overhang can be provided. In particular, this is the already existing from the Velcro connection between the holder 102 and mop cover 103 existing on the mop cover 103 Velcro 128 into consideration, the as in Fig. 6d - Can protrude into the edge protection edge 124 for stabilization. Instead, however, in the actual edge area - as in Fig. 6c shown - an additional gain 129 may be provided.
