Definitions
- the invention relates to a vacuum cleaner nozzle, in particular for use in a feed direction R1 and return direction R2, with a nozzle head and a nozzle sole, in which at least one suction mouth is formed, which at least in the feed direction R1 dirt catch elements are upstream.
- dirt-catching elements in particular made of plastic or natural bristles in the form of strips, are for example arranged rigidly on the nozzle head and / or on the nozzle sole.
- DE 88 14 882 U1 or DE 196 30 241 C2 discloses vacuum cleaner nozzles on a vacuum cleaner which have bristle strips or strips arranged on all sides or in parallel, in which openings are formed or partially cut out parallel to the bottom by approximately half the height are to let such a coarse suction material.
- a disadvantage of such embodiments of the bristle strips is the occurrence of "pushing ahead" of dirt particles at not recessed areas. The dirt bound at such points is not directly required to the suction mouth and can still only be cleaned via a separate operation.
- a vacuum cleaner nozzle which has a plurality of pile threads, which are bundled or tied together at the root portions, which are arranged upright at the front and rear of the suction and provided at the front with recesses. These recesses allow dirt through.
- the individual pile threads may be bundled at their root portions and arranged at an angle to the longitudinal direction.
- the back side of the brush area is designed continuously and without interruptions, thus preventing the passage of dirt during a feed movement.
- Fig. 21 of DE 690 20 639 T2 shows a vacuum cleaner nozzle, which is circumferentially equipped with bundles of individual pile threads.
- a suction mouthpiece for a vacuum cleaner in which a worktop is arranged on the nozzle sole of the suction nozzle, which are formed a plurality of aligned to the ground nubs, wherein adjacent passage openings for the sucked solids are present, and the nubs facing the ground have a smooth surface.
- a disadvantage of this nozzle is that this embodiment only facilitates an improvement in the reception of fibrous materials, but does not allow for the absorption of coarse dirt.
- DE 10 2005 045 575 A1 discloses a one-piece bristle strip for a Staubsauger convinceddüse, with a carrier element and bristles, wherein the carrier element and the bristles are integrally formed and wherein the carrier element consists of a hard component and the bristles of a soft component and in the 2-component - Plastic injection molding are made.
- the invention has for its object to provide a comparison with the prior art improved vacuum cleaner nozzle which feeds smaller as well as larger dirt particles and fibrous materials, especially with simple forward or backward movements of the nozzle largely without additional movements, far safer the suction mouth.
- the vacuum cleaner nozzle according to the invention is based on generic vacuum cleaner nozzles in that dirt catching elements on the nozzle head and / or arranged on the nozzle sole rigidly and / or optionally at least partially retractable into the nozzle head, wherein in the feed direction R1 and / or remindschubides R2 at least a part of the dirt traps from Suction mouth have such a tapered cross-section Q, that on the side facing the suction mouth designed as a dirt catch hollow region is formed, wherein the side of each dirt catch element openings are provided for the passage of dirt particles.
- This embodiment of the dust catching elements has the advantage that dirt particles easily pass the individual dust catching elements into the interior of the vacuum cleaner nozzle towards the suction mouth in the first feed direction R1 through the aerodynamic shape. Dirt particles, which have not yet reached the suction mouth in the first feed movement R1, are retained in the subsequent return movement R2 in the hollow region acting as a dirt trap and prevented from escaping from the area of the vacuum cleaner nozzle.
- the dirt-catching elements Preferably, at least a part of the dirt-catching elements have a wedge-shaped, arrowed, hemispherical, hyperbolic and / or parabolic-shaped cross section. All of these shapes are characterized by a flow resistance coefficient favorable in relation to their arrangement to the suction mouth in a thrust direction R1 or R2 and thus optimally configured for passing the dirt particles past the suction mouth.
- the individual dirt-catching elements of a series may have the same or different shapes.
- the openings are preferably realized by spaced apart adjacent dirt catching elements and / or by a recess in dirt catching elements arranged without spacing from one another.
- the distance between adjacent dirt-catching elements or the recess adjacent dirt-catching elements is particularly chosen so that on the one hand sufficient space is granted, so that even larger dirt particles can flow past the gaps unhindered.
- the distance between the dirt trapping elements is to be selected so narrow that the air flow of the vacuum cleaner nozzle absorbs the dirt particles supplied to the suction mouth.
- the distance between adjacent dirt catch elements or the recess adjacent dirt catch elements can be designed differently in a row. Furthermore, it is ensured by such freestanding dirt trap elements that capillary effects between adjacent elements and thus the binding of liquid in the dirt trap elements are largely avoided. This makes the vacuum cleaner nozzle more hygienic to handle.
- the dirt-catching elements can be aligned in one or more, preferably staggered, rows towards the suction mouth.
- the debris on the front row is deflected and moved in the direction of the nozzle center.
- the subsequent series of dirt trap elements deflects the dirt particles on.
- the dirt particles are deflected with the support of the upcoming air flow preferably to the nozzle mouth out. Dust particles which are already located after a successful deflection in front of a hollow area, are thus retained in a backward movement R2 of the nozzle in the cavity.
- the dirt particles are thus conveyed closer and closer to the nozzle mouth, similar to a mit step method. Due to the arrangement of the dust catching elements in staggered rows, closing The airflow from the suction mouth could also be held in the middle of the nozzle, thus enabling effective absorption of the particles via the suction mouth.
- these dirt-catching elements can be arranged wholly or partially substantially perpendicular to the nozzle sole.
- a vertical arrangement of the dust-collecting elements also has the advantage that, when the nozzle is manufactured, simple device means suffice for manufacture.
- the dirt trapping elements can also be at least partially offset and / or arranged at an angle ⁇ to the nozzle sole.
- Dust catching elements which are decoupled or arranged at an angle to the nozzle sole have, by virtue of their greater extent, the advantage of being able to form larger-scale hollow areas acting as a dirt trap.
- dirt catching elements have a lower, yielding rigidity, and this property is advantageous in particular in the cleaning of sensitive and / or uneven surfaces.
- the above embodiments of cranked or angularly arranged dirt-catching elements also have the advantage that at least part of the dirt-catching elements can be formed laterally out of the base surface formed by the nozzle head and / or nozzle sole, so that facilitated edge suction is achieved. As a result, a dust receptacle from corners or on walls and baseboards is ensured along without touching the nozzle head with the wall or the furniture in an advantageous manner.
- the ends of the dirt trapping elements form a predominantly flat surface, whereby a highly effective dirt trap is formed depending on the stroke and based on the floor surface to be cleaned.
- a polishing of the soil surface is advantageously achieved in the return movement.
- At least individual dirt-catching elements can have slots and / or recesses. Different stiffnesses of individual dirt catching elements can be most easily achieved with slots or recesses. achieve different sizes. Also, in a simple manner, the rigidity of a dirt trap element (further) can be reduced.
- the dirt-catching elements consist at least partially of a soft component
- this has lower static friction compared to a floor covering to the advantage.
- Preventive elements made of soft components also advantageously prevent scratching of furniture, as is usually the case when corner suction through the nozzle head is usually observed.
- dirt-collecting elements formed from soft components advantageously leave no traces of abrasion on the surfaces.
- the dirt trap elements with the nozzle sole are made in one piece, in particular in a 1K or 2K plastic injection molding process, inexpensive and easy to install.
- individual dirt-catching elements may be injection-molded onto the nozzle sole in an injection molding process, which increases the ease of assembly on account of the one-piece effect achieved thereby.
- the nozzle sole may be made of a different material than the single or all of the dirt traps.
- the nozzle sole then consists, for example, of a hard component and the dirt-catching elements at least partially of a soft component. The choice of materials with different degrees of hardness for different areas of the nozzle allows a versatile integration of functionalities in a nozzle.
- areas of the nozzle sole may be made of PP, PP-GF or the like.
- the individual elements can be made of TPE, PVC, silicone, elastomer or the like, for example.
- the stability-determining regions of the carrier part can be defined with regard to their strength-determining function; at the same time, the individual dirt-catching elements can be sufficiently flexible.
- this eliminates in this way after the manufacture of the nozzle sole with the dirt trapping elements further assembly steps, such as the attachment of further stiffening elements, which allows cost savings.
- further assembly steps such as the attachment of further stiffening elements, which allows cost savings.
- the integrity due to the lack of bonding materials, such as adhesives adds to the higher reliability of the bristle molding.
- the dirt trapping elements may be made of individual plastics and / or natural hair bristles exist. With different materials can be in a simple manner different, esp. Antistatic properties and / or functionalities such as fold-away areas, combine, and represent effective color designs.
