Description

Invention Field

[0001] The present invention relates to a cleaning element comprising a carrier having an elongated fringe fixed thereon, wherein the fringe surrounds a central region of the carrier. Background Technology

[0002] Such a cleaning element is known from DE 102017004809 B3. In previously known cleaning elements, an elongated textile fringe is fixed to the end of a carrier. The fringe has multiple interconnected strands of yarn. Sometimes referred to as a wire harness, these strands are formed from plastic fibers. Therefore, they have a large volume and strong water absorption capacity. Previously known cleaning elements were used for wet (Nass-) or damp cleaning (Feuchtreinigung) of floors.

[0003] Previously known cleaning elements are particularly suitable for wringing out the fibers in a rotary spin dryer after cleaning. For this purpose, a cleaning device with the cleaning element securely attached is pressed into a basket-shaped container, which can rotate about a longitudinal axis, and excess water is spun out from the fibers. In this process, it is particularly unnecessary to remove the fibers from the cleaning device for cleaning and spun drying.

[0004] While previously known cleaning elements have high cleaning efficiency, removing dirt that is firmly attached to the surface to be cleaned presents a problem. Summary of the Invention

[0005] The present invention achieves the above-mentioned objective through the features of claim 1. Advantageous design embodiments are described in the dependent claims.

[0006] The cleaning element according to the invention includes a carrier with an elongated fringe fixed thereon, wherein the fringe surrounds a central region of the carrier, the central region corresponding to a receiving portion, in which a retainer is inserted, the retainer corresponding to a planar cleaning body.

[0007] The cleaning element, consisting of a fringe surrounding a central area, is fixed to the support. The fringe can be arranged in a ring. During normal use, the fringe extends from the side below the support, ensuring that the planar cleaning element, in addition to the fringe, also contacts the surface to be cleaned. The cleaning element is centrally positioned below the support, allowing for greater contact pressure to be applied. Thus, the planar design of the cleaning element achieves excellent cleaning results even for firmly attached dirt.

[0008] The fringe can be fastened to a ring-shaped fringe holder, which defines the boundary of the receiving portion. The holder is form-fitted to the fringe holder, which is fixed to a carrier. For this purpose, the fringe holder has a number of receiving elements for accommodating the fringe. Preferably, the fringe is also securely fastened to the fringe holder. This fastening is preferably implemented by means of material fit or shape fit. For example, fastening can be implemented by means of adhesive bonding, knotting, or sewing.

[0009] The retainer is preferably held in the receiving portion in a form-fitting manner. This allows for installation in a particularly simple and cost-effective way. In particular, the retainer can be subsequently fastened into the receiving portion of an existing carrier. The retainer and the receiving portion preferably form a locking engagement.

[0010] The fringe retainer and the retainer are preferably fastened to the carrier and the fringe retainer respectively by means of a locking engagement. For this purpose, the fringe retainer and / or the retainer may be provided with, for example, protrusions, hooks, recesses or such shaped engaging elements.

[0011] The fringe retainer and retainer can be combined with the cleaning body and fringe to form a pre-assembled unit that is fastened to the underside of the carrier. In particular, the unit formed by the fringe retainer with the fringe and the retainer with the cleaning body can be sold as a pre-assembled unit, so that the fringe and cleaning body can be replaced after the unit is discontinued due to wear.

[0012] In particular, the retainer with fringe and the retainer with cleaning body can be replaced independently. Furthermore, different retainers can have different cleaning bodies, allowing the selection of a cleaning body that matches the cleaning task and securing it to the retainer. Similarly, different fringe retainers can have different fringe designs, with the same fringe selected and secured to the cleaning element.

[0013] The cleaning body can be fixed to the retainer. Preferably, the cleaning body is fixedly connected to the retainer. For example, the connection can be achieved by adhesive bonding or ultrasonic welding using a material-fitting method. Alternatively, the cleaning body can be fastened to the retainer by means of a sewn connection.

[0014] The cleaning body is preferably constructed of a textile fabric. The cleaning body may include microfibers. Furthermore, the cleaning body may be equipped with stiffer fibers that have an abrasive effect. In an advantageous design, the stiffer fibers and microfibers are arranged in zones on the cleaning body.

[0015] The cleaning edge can be composed of a single material or formed from multiple materials. The cleaning edge may, in particular, include microfibers. Furthermore, the cleaning body can have different cleaning edges with varying properties. For example, it can have harder edges, softer edges, microfiber-containing edges, absorbent edges, and abrasive edges. In an advantageous design, the cleaning body includes edges of varying coarseness. Coarser edges can be arranged in a first zone, and finer edges can be arranged in a second zone. Edges with different cleaning properties can also be arranged in each zone. For example, harder edges, softer edges, microfiber-containing edges, absorbent edges, and abrasive edges can be arranged in each zone.

[0016] The carrier, the edge retainer, and the retainer are preferably formed of an injection-moldable material. In particular, the edge retainer and the retainer can be formed of polypropylene.

[0017] The fringe retainer, which has a fixed housing, can be removed from the carrier and made available for machine washing. This allows for a particularly thorough and separate cleaning of the fringe and the cleaning body. In addition to better cleaning, this also has the advantage of extended service life.

[0018] The retainer may have a wraparound edge. Preferably, shape-fitting elements are introduced on the outer side of the wraparound edge, which engage with consistent recesses in the fringe retainer. Thus, the fringe retainer and the retainer are essentially equally separable from each other.

[0019] The retainer can have a cover element with a planar structure, on which the cleaning body is fixed. The cover element presses the cleaning body planarly onto the surface to be cleaned, achieving excellent cleaning results. Furthermore, the cover element forms a retainer with particularly stable shape.

[0020] The cover element may have a wraparound edge that projects radially outward beyond the edge. Preferably, this edge is constructed such that it at least partially protrudes beyond the burr holder. Thus, after the holder is inserted into the burr holder, the edge partially covers both the burr holder and the burr secured to it. This causes the burr fixed to the burr holder to shift laterally, protruding from the side. Advantageously, this results in a particularly large overall volume for the cleaning element, and the cleaning body is in full contact with the surface to be cleaned. Because the burr protrudes outward from the side, it does not enter between the cleaning body and the surface to be cleaned.

[0021] Preferably, at least one through-hole is introduced into the cover element. When the cleaning element is cleaned in a wash tub (sometimes called a mop tub), the carrier is surrounded by cleaning fluid. During this process, the cleaning fluid can enter the interior of the carrier and, consequently, the retainer. The through-hole ensures that the liquid in the retainer can flow out through the cleaning body.

[0022] The through-hole can be introduced into the center of the cover element. This allows the liquid in the holder to flow out, and also enables a particularly space-saving structure, as the components of the carrier can extend into the through-hole of the cover element.

[0023] According to another advantageous design, at least one slit is locally introduced in the corner region between the edge and the cover element. Viewed from a top view, the cleaning element according to the invention is preferably constructed as rotationally symmetrical and is particularly suitable for spin-drying in a rotary dehydrator. For this purpose, the cleaning element is placed in a basket-shaped, rotatable receiving portion. Rotation spins the cleaning liquid from the edge. Rotation also causes the liquid in the retainer to move towards the edge, where it flows out through at least one slit.

[0024] The carrier may have a recess on the side opposite the receiving portion, which has an engagement for securing the handle. This engagement may be configured as a joint-type engagement. This recess allows for better force distribution during cleaning operations.

[0025] At least one second through-hole can be introduced into the recess, establishing a flow connection between the recess and the receiving portion. Thus, cleaning fluid that may accumulate in the recess can flow through the through-hole toward the retainer fixed in the receiving portion. The fluid can then be discharged through the through-hole introduced therein via the retainer. Attached Figure Description
