Definitions

  • the invention relates to a flat jet nozzle, in particular for a high-pressure cleaning device, with the features of the preamble of claim 1.
  • Such flat jet nozzles are used in order to be able to cover an object with a fanned-out fluid jet.
  • pressurized water may be used as the fluid to which a cleaning chemical may be added.
  • the water jet can be directed to an object to be cleaned, wherein the object can be swept by the fanned water jet.
  • the use of the flat jet nozzles is not limited to pressurized water, for example, such flat jet nozzles can also be used to produce a fanned air or water vapor jet.
  • the air jet can be directed, for example, to an object to be dried.
  • it may be provided that such flat jet nozzles are used on drying devices of vehicle washing systems.
  • Flat-jet nozzles with a slot-shaped nozzle opening are known for forming a flat jet.
  • Such nozzles are for example in the DE 29 27 737 C2 and in the US 6,402,062 B1 described.
  • the beam shaping takes place in such nozzles directly to the slot-shaped nozzle opening.
  • Flat jet nozzles are also known in which a fluid jet which is round at the nozzle opening in cross-section is formed into a flat jet by a subsequent impact on lateral walls. Such nozzles are used, for example, for irrigation of parks.
  • flat jet nozzles are known in which the beam shaping takes place already upstream of the nozzle opening in a beam-forming section of the flow channel.
  • Such nozzles are for example in the EP 0 683 696 B1 and in the DE 694 00 060 T2 described.
  • the beam shaping takes place in that two concave extensions of the flow channel, which otherwise taper continuously in the flow direction of the fluid, are provided diametrically opposite one another directly upstream of the nozzle opening.
  • the lateral extensions lead to a deflection of the fluid in such a way that it has a fanned out jet form after emerging from the nozzle opening.
  • Such flat jet nozzles have proven themselves in practice, however, the fluid undergoes a not inconsiderable flow loss in the flat jet nozzle and the manufacture of the flat jet nozzles is associated with considerable costs due to the elaborate processing of the nozzle body.
  • the flat jet nozzle has a nozzle body, which is penetrated by a flow channel.
  • the flow channel extends from an inlet opening to an outlet opening, wherein its flow cross-section continuously tapers.
  • the outlet port forms a nozzle opening of the flat jet nozzle and has an elongated (elliptical) shape. Upstream of the nozzle opening, the flow channel forms a region in which its flow cross section continuously changes from a circular shape in an elliptical shape.
  • a flat jet nozzle is known with an elliptical nozzle opening, which is immediately upstream of a tapered in the flow direction circular cone-shaped region of a flow channel.
  • a surge shower having a flow passage extending from an inlet opening to an outlet opening.
  • the inlet opening has an elliptical, approximately circular cross section and the outlet opening is configured rectangular.
  • the surge shower is made of a glass fiber reinforced plastic material.
  • Object of the present invention is to develop a flat jet nozzle of the type mentioned in such a way that the fluid is subject to low flow losses in the formation of a flat jet and the flat jet nozzle can be produced inexpensively.
  • a continuous, that is stepless, and edgeless transition of the flow cross-section of the flow channel from a circular shape to an elliptical shape takes place.
  • the flow cross-section decreases the flow channel continuously in the flow direction of the fluid.
  • the continuous reduction of the flow cross-section causes the fluid to be accelerated uniformly. Due to the continuous transition of the flow cross-section from a circular shape into an elliptical shape, the fluid in two diametrically opposite peripheral regions of the beam-forming section is deflected more towards the center of the jet than in the remaining peripheral regions of the beam-shaping section.
  • the fluid forms a flat jet as it passes through the nozzle opening. Since the transition of the flow cross-section which continuously tapers in the flow direction from a circular shape into an elliptical shape takes place continuously without steps or edges, the fluid is accelerated without a detachment of the fluid from the wall of the beam-forming portion. Flow losses can be kept low by the continuous transition.
  • the flat fan nozzle according to the invention is therefore characterized by a low-loss beam shaping. Due to the omission of steps and edges in the interior of the beam-shaping section, the flat-jet nozzle according to the invention can be produced inexpensively, for example, by an injection molding process, it being possible to use a plastic material or alternatively metallic or ceramic materials for the production.
  • the flat fan nozzle according to the invention also has the advantage that with its help, an improved cleaning effect in the vicinity can be achieved, since the flow is focused on the nozzle opening virtually fog-free and precise.
  • the beam-shaping section has an end region immediately upstream of the nozzle opening, in which the flow cross-section of the flow channel is continuous with an elliptical shape in a circular shape, wherein the nozzle opening is also configured circular.
  • a continuous transition of the flow cross-section starting from a circular shape over an ellipse shape, takes place back into a circular shape, the flow cross-section continuously decreasing in the flow direction of the fluid.
  • the flat jet nozzle can be connected, for example, to a jet pipe.
  • the jet pipe can have a circular flow cross section.
  • the contour of the flow channel can continuously taper, starting from the circular shape, a continuous transition first into an ellipse shape and then again in a circular shape, so that the fluid through the also circular Nozzle opening in the form of a flat jet can be discharged to the outside, wherein the fluid accelerates smoothly and without detachment from the wall of the flow channel and flow losses are reduced to a minimum.
  • a shaping of the flow channel with a circular inlet cross-section and a circular nozzle opening simplifies the production of an injection molding tool and the demolding of the flat jet nozzle during its production.
  • the orientation of the main axis of the elliptical shape of the flow cross section remains the same in an advantageous embodiment of the invention along the entire beam forming section.
  • the orientation of the main axis of the elliptical flow cross section in the space along the entire beam-forming section remains unchanged.
  • the nozzle opening has a tear-off edge for the fluid, which is arranged in a plane oriented perpendicular to the longitudinal direction of the flow channel.
  • the flow channel In the region of the nozzle opening, the flow channel has its smallest flow cross-section. The flow of the fluid ruptures at the nozzle opening from the wall of the flow channel.
  • the nozzle opening forms a tear-off edge for this purpose. It is advantageous, in particular for component demoulding, if the tear-off edge is arranged in a plane which is aligned perpendicular to the longitudinal direction of the flow channel.
  • the inner wall of the flow channel is preferably defined by a three-dimensional free-form surface, wherein the curvature of the free-form surface changes continuously, at least in a longitudinal sectional plane of the flow channel.
  • the three-dimensional free-form surface preferably has a constant change in curvature with respect to the flow direction of the fluid.
  • the three-dimensional freeform surface is defined by Bézier curves.

  • FIG. 3 At six positions of the beam-forming section 28, including the nozzle opening 32, the flow cross-sections of the flow channel 24 are illustrated.
  • the flow channel 24 In position 1 at the transition between the inlet section 26 and the beam-shaping section 28, the flow channel 24 has a circular shape. In the respective positions 2, 3, 4 and 5 arranged at a mutual distance of about 20% of the total length of the beam-forming section 28, the flow channel 24 has an elliptical flow cross-section, wherein the eccentricity of the ellipse continuously increases.

In position 6 of FIG. 2 is the nozzle opening 32, which is designed circular.
  • the fluid flowing through the flow channel 24 experiences, for example pressurized water, a beam shaping such that a flat jet is formed.
  • a beam shaping is achieved by subjecting the fluid in the diametrically opposite circumferential regions of the beam shaping section 28, which are penetrated by the main axis 42 of the elliptical flow cross section, to a stronger deflection in the direction of the longitudinal axis 28 than in the remaining peripheral regions of the beam shaping section 28 are aligned substantially parallel to the main axis 42.
