Embodiment Construction

[0010] figure 1 A bottom view of a vacuum cleaner appliance according to a first embodiment of the present invention is illustrated. Only essential elements are shown, other elements not relevant to the present invention, such as wheels and brushes, are not shown. The vacuum cleaner appliance (eg nozzle) 1 has a suction opening 3 and a lint pickup 5 with a plurality of triangular elements 5a to 5d directed towards the suction opening 3 . In an embodiment, another similar lint pickup is placed at the other end of the suction port 3 . Each triangular element 5a to 5d is mounted in a respective recess having 3 edges, one of which (shown in solid lines) is parallel to the suction opening 3 and bears the reference numerals 7a to 7d Two of the edges (shown in dashed lines) are oriented along a line forming an angle between 20° and 70° with the longitudinal axis A-A of the suction opening 3, the The angle is 120°. The pair of boundaries 7a to 7d form the edge directed towards the...

Abstract

In a vacuum cleaner utensil (1) comprising a suction opening (3) and a lint picker (5) at a side of the suction opening (3), the lint picker (5) is mounted in a recessed portion having a plurality of rims (7a-7d) along lines at an angle between 20 degrees and 70 degrees to a longitudinal axis (A- A) of the suction opening (3) that form edges pointing towards the suction opening (3). Preferably, the lint picker has a plurality of triangular-shaped elements (5a-5d). Preferably, the lint picker has a plurality of elements (5a-5d) that have first and second boundaries along lines at an angle between 20 degrees and 70 degrees to the longitudinal axis (A- A) of the suction opening (3), an angle between the first and second boundaries not exceeding 120 degrees. Another aspect of the invention provides a vacuum cleaner comprising a suction unit, and a nozzle arranged for being coupled to the suction unit, wherein the nozzle is formed by such a vacuum cleaner utensil (1).

Description

technical field [0001] The present invention relates to a vacuum cleaner appliance, ie to a vacuum cleaner nozzle in the case of a vacuum cleaner with a separate nozzle, or to a robot vacuum cleaner with an integrated nozzle. The invention also relates to a vacuum cleaner provided with a vacuum cleaner nozzle. Background technique [0002] WO0226097 discloses a floor tool for vacuum cleaning floor surfaces comprising a base plate with suction channels. The suction channel is bounded on at least one side by a working edge for engagement with the floor surface. A lint cleaner is positioned next to the suction channel and is separated from the suction channel by a working edge. The lint pickup is mounted on the surface of the floor tool which is inclined relative to the plane in which the working edge lies. A lint picker is a strip of material in which a plurality of tufts of fine hairs are secured. All clusters in a cluster are aligned in the same orientation relative to t...
