Definitions

  • the invention relates to a floor nozzle for vacuum cleaners, the a housing with an air duct, one around one in use, when vacuuming a horizontal floor surface horizontal axis pivotally connected to the housing Connection piece for a suction pipe and a Has suction head with a suction mouth on the bottom.
  • a swivel or tilt joint changes the Handle height when vacuuming, e.g. by swinging movements of the Poor, different body size and posture Operator, balanced so that the suction head when Suction always lies flat on the floor.
  • the connecting piece can be formed in two parts and an angled tube rotatably connected to the nozzle exhibit. Is the connecting piece additionally with a rotatable angled tube, so can by a Rotary movement of the suction pipe connected to the connecting piece the orientation of the suction head in the suction direction to be controlled.
  • the maximum steering angle is through the Curvature of the angle tube is specified and is in the Practice about 30 to 35 °.
  • the working width of the nozzle is reduced only marginally through the steering options, so the floor nozzle for vacuuming narrow niches is common cannot be used.
  • connection piece In a floor nozzle known from DE-A 28 46 847 Suction head swiveling to the horizontal axis Housing connected, which at its rear, the Connection piece adjacent area by means of a roller is supported on the ground.
  • the housing is as a suction channel educated.
  • the articulated connection of the connection piece is shifted backwards and holds you clear distance from the suction head.
  • the suction pipe forces applied are greater than those on the rear Roller arranged at the end of the housing introduced into the ground, so the suction head is just under the effect of the suction pressure is on the floor and not additionally vertical forces from the operator when vacuuming applied and transferred via the suction pipe, applied becomes.
  • the connection piece is the orientation of the suction head controllable relative to the suction direction, the working width the nozzle, however, due to the limited angulation only insignificantly reduced. For vacuuming narrow niches this version is also unsuitable.
  • the suction pipe on the top of a suction head is cardanic connected (Nilfisk Advance company publication).
  • a flexible hose is inserted into the gimbal. Due to the cardanic mounting of the intake manifold the one formed with a rectangular contact surface Suction head both transverse to the suction direction and along the Suction direction to be aligned so that the floor nozzle both for vacuuming large floor areas and for vacuuming narrow niches can be used.
  • the vertical component the one introduced by the suction pipe during the suction process Power is transferred to the suction head and works adversely affect the pushing force required for suction out.
  • the risk of the suction head being pressed so deeply into the pile is that there is a large negative pressure in the suction mouth builds up and the suction head sticks to the floor, so that proper suction is no longer possible.
  • the invention has for its object a floor nozzle specify, the suction head aligned to the suction direction can be and which with a low pushing force both on smooth floors and on textiles Flooring is movable.
  • the suction head is rotatable about a vertical axis of rotation with respect to the horizontal axis the housing is connected and that the housing is outside of the rotation range of the suction head is supported on the bottom is.
  • the vertical axis of rotation can be in relation to the Longitudinal axis of the suction head, which has the greatest length, be arranged in the middle or off-center.
  • the angle of rotation for the rotation of the suction head around the vertical axis of rotation is at least 90 °, so one with a rectangular Supported trained suction head both crosswise and aligned in the longitudinal direction to the suction direction can be and depending on the orientation of the suction head large floor areas effectively vacuumed as well as narrow Niches can be cleaned.
  • the floor nozzle in both directions of rotation each 90 ° movable. Angle of rotation of more than 90 ° as well Full revolutions should not be excluded.
  • the suction head in all Functional positions can be tilted around a horizontal axis stored. This enables particularly good ground contour following of the suction head on uneven floors.
  • the housing can have a sliding surface on the bottom side Have support or with one or more, preferably rollers arranged on an axis for be provided on the bottom side support.
  • the suction head points expediently a substantially rectangular contact surface on, the width of the suction head preferably is not significantly larger than the width of the channel trained housing. Other geometries for the contact surface should not be excluded.
  • the angle of rotation of the Suction head around its vertical axis of rotation is at least 90 °.
  • the suction head can be used in bearing cups rotatably arranged balls to the bottom Be equipped. Through storage on balls the suction head is easy to move on all floor coverings, regardless of whether it is transverse or longitudinal to the suction direction is aligned. It goes without saying that too other support elements, for example castors, swivel castors, Gliders and the like can be provided.
  • the arrangement for the rotary movement of the suction head has preferably locking elements to secure the suction head against rotation in preferred positions.
  • locking elements it can are spring-movable locking elements; manually actuatable switching elements are not to be excluded his. It is also within the scope of the invention that the Suction head through one acting around the vertical axis of rotation Return spring is held in a preferred position, so that the suction head passes through when hitting an obstacle a corresponding rotary movement can avoid.
  • the suction head can be used as a static floor nozzle without rotating Internals be formed, the suction mouth channel-shaped is formed and extends over the entire length of the floor nozzle extends and is limited by suction mouth edges. It understand that thread lifters, rubber lips and the like can be provided in a known manner.
  • the suction head can also contain retractable and extendable bristles. at In this version, the suction head has an upper part, one in Upper part vertically movable bristle carrier plate, one Actuation switch for the bristle carrier plate and a Sliding sole, at least on the bristle carrier plate a bristle strip is connected with a lifting movement the bristle carrier plate by a base Slot of the suction head is retractable and extendable.
  • the teaching according to the invention is not based on static floor nozzles limited. It is also within the scope of the invention that the suction head is a brush roller arranged in the suction mouth has that by an electric motor or by a suction air stream rotating turbine is driven.
  • the floor nozzle shown in the figures has a housing 1 with an air duct, one around a horizontal one Axis pivotally connected to the housing 1 Connection piece 2 for a suction pipe and a suction head 3 with a suction mouth on the bottom.
  • the pivotability of the connecting piece 2 is indicated by dashed lines in Fig. 1.
  • the connecting piece can also be formed in two parts be and from one in the air duct of the Housing 1 tilting connector 2 and a rotatable angularly connected to the nozzle 2 Pipe 4 exist. Such an execution is in the 3 and 4 indicated.
  • the suction head 3 has a substantially rectangular shape Contact surface and is about a vertical axis of rotation 5 rotatably connected to the housing 2.
  • the housing 2 is outside the rotation range of the suction head 3 on the bottom supported. It is supported by rollers 6, which is channel-shaped at the rear end Housing 1 in the area of the tilt-connected Connection piece 2 are arranged.
  • the angle of rotation for the rotary movement about the vertical axis of rotation 5 is at least 90 ° so that the suction head is both transverse aligned with the direction of suction as well as along the direction of suction can be.
  • the one shown in FIGS. 1 and 3 first position is an effective one Vacuuming large floor areas possible. In the in Fig.
  • the figures show preferred positions of the suction head 3.
  • the suction head 3 can be locked.
  • the arrangement for the rotary movement of the Sucking head 3 locking elements which as locking elements or manually operable locking elements can be executed.
