Definitions

  • the invention relates to a fluidic component according to the preamble of claim 1 and a fluid distribution device that includes such a fluidic component.
  • fluid jets In fluid distribution devices such as cleaning devices, it is desirable to be able to generate fluid jets with different spray characteristics in order to meet the requirements in different areas of use. For example, there is a need for a device that can selectively generate omnidirectional and fan beams. In this way, stubborn dirt can be treated and cleaned with the high jet impulse of an omnidirectional jet and sensitive surfaces can be treated and cleaned extensively with the locally lower jet impulse of a fan jet (i.e. with a lower area performance). A fan jet or a fluid jet with a large spatial distribution of the fluid is well suited for rinsing.
  • nozzle systems are known from the prior art in which, for example, a slide or a rotary mechanism is used to switch back and forth between a plurality of nozzles, each with different spray characteristics.
  • Each nozzle has a defined and unchangeable spray characteristic and gives the fluid jet a jet shape.
  • nozzle systems generate quasi-static or static and non-oscillating fluid jets.
  • nozzles are known from the prior art, which are set in motion by means of kinematics or a (movable) device.
  • the kinematics or (moving) device includes moving components that are subject to high wear are exposed. The costs associated with manufacture and maintenance are correspondingly high.
  • due to the moving components a relatively large installation space is required overall.
  • fluidic components In order to generate a moving fluid flow (or fluid jet), fluidic components are also known which generate a fluid jet oscillating in one plane.
  • the fluidic components do not include any moving components that serve to generate a moving fluid flow. As a result, they do not have the disadvantages resulting from the moving components compared to the nozzles with moving components.
  • the fluidic component is intended to generate a moving, oscillating or pulsating fluid jet.
  • fluid flow patterns of an oscillating jet are sinusoidal jet oscillations, rectangular, sawtooth or triangular jets, spatial or temporal jet pulsations and switching.
  • Such fluid jets are used, for example, to evenly distribute a fluid jet (or fluid stream) over a target area.
  • the fluid flow can be a liquid flow, a gas flow, a multi-phase flow (for example wet steam) or a fluid containing particles.
  • the fluidic components known from the prior art for generating a moving fluid flow usually have a fixed spray property with a constant volume flow and/or inlet pressure of the fluid.
  • US 6,497,375 B1 and WO 02/07893 A1 fluidic components with different operating points are described, at which air can be directed into the fluidic components by means of closable air penetration holes and the oscillation can be switched on and off in a targeted manner. It is thus possible to switch between a spray jet with a fixed oscillation angle and a punctiform spray jet. From the U.S.
  • a device which comprises a plurality of fluidic components, each with different spray properties, of which one fluidic component can optionally be rotated into the fluid jet and thus (depending on the choice of fluidic component) a fluid flow with different spray properties can be generated.
  • Such a device requires a relatively large amount of space overall.
  • the spray characteristics of the exiting fluid flow can only be varied between a predetermined number of possibilities.
  • the object of the present invention is to create a device that is designed to generate a moving fluid jet, the spray characteristics of which can be set before operation or changed during operation, the device having a high level of reliability and correspondingly low maintenance costs.
  • the fluidic component comprises a flow chamber through which a fluid stream can flow, which enters the flow chamber through an inlet opening of the flow chamber and exits the flow chamber through an outlet opening of the flow chamber.
  • the inlet port and the outlet port are located on opposite sides of the flow chamber.
  • At least one means for generating an oscillation of the fluid flow at the outlet opening is provided in the flow chamber.
  • the means for forming an oscillation can be at least one bypass channel, for example. Alternatively, other means for forming an oscillation of the fluid flow can also be provided.
  • the fluidic component is characterized in that the flow chamber has a changeable shape.
  • a device can be provided which acts in a targeted manner on the fluidic component and thus brings about a change in the shape of the flow chamber.
  • the change in shape of the flow chamber is preferably reversible. This means that the device can bring about a change in shape and also reverse it again.
  • various parameters of the fluidic component such as the shape or the volume, can be changed. This allows the spray characteristics of the exiting fluid stream to be changed without changing the parameters of the fluid flowing through the fluidic component, such as the type of fluid, the inlet pressure of the fluid, the inlet velocity of the fluid and the volumetric flow rate.
  • the shape can be changed steplessly (or alternatively in steps), so that the spray characteristics of the emerging fluid flow also change steplessly (in steps) and can thus be specifically adapted to a specific application.
  • the spray characteristics can relate in particular to the spray angle that is achieved by means of the invention fluidic component is adjustable.
  • the exiting fluid jet can be modulated between a point jet and a fan jet.
  • the fluidic component according to the invention can be used to generate a directed fluid jet with adjustable spray characteristics for targeted wetting, dripping or sweeping over a surface. Since the fluidic component according to the invention allows the emerging fluid flow to perform an oscillating movement and its spray properties to be adjusted, the cleaning, surface wetting or surface treatment performance can be massively increased.
  • the fluidic component can be adapted to different cleaning requirements.
  • the fluidic component according to the invention is therefore of interest for high, medium and low-pressure cleaning, as well as for surface treatment and surface coating.
  • the change in the shape of the flow chamber can take place before the fluidic component is put into operation or during operation, that is to say while a fluid is flowing through the fluidic component.
  • the fluid entering the flow chamber through the inlet port may be pressurized from 0.001 to 6000 bar (relative to ambient pressure).
  • the pressure can be between 0.005 and 1800 bar.
  • a pressure range between 0.05 and 1100 bar is particularly preferred.
  • so-called low-pressure applications such as washing machines, dishwashers and fluid distribution devices (sprinklers, hand showers or cleaning systems)
  • an inlet pressure of 0.01 bar to 12 bar above ambient pressure is advantageous.
  • the inlet pressure is preferably between 6 bar and 120 bar above ambient pressure.
  • the inlet pressure can be over 40 bar.
  • the oscillation frequency of the oscillating fluid flow emerging from the fluidic component can be between 0.25 Hz and 40 kHz.
  • a preferred frequency range is between 3 Hz and 600 Hz.
  • the fluid can be a gaseous, liquid or multi-phase, free-flowing medium, which can also be afflicted with particles.
  • the fluid is a liquid (e.g. water)
  • the geometric parameters (shape, size, number and shape of the bypass channels, (relative) size of the inlet and outlet openings) of the fluidic component are selected in such a way that the pressure to which the fluid flow is subjected when it passes through the inlet opening enters the fluidic component, is essentially broken down at the outlet opening.
  • the parameters can be selected such that the pressure to which the fluid flow is subjected when it enters the fluidic component via the inlet opening is already reduced before (upstream) the outlet opening.
  • the flow chamber is delimited by a boundary wall.
  • the boundary wall does not have to form the external appearance of the fluidic component.
  • the boundary wall can be formed by the inner surface of a hollow body, with the cavity of the hollow body forming the flow chamber.
  • the outer appearance of the fluidic component is then defined by the outer surface of the hollow body.
  • the outer surface of the hollow body can in particular be essentially cuboid and have interruptions for the inlet opening and the outlet opening.
  • the flow chamber has a main flow channel, which connects the inlet opening and the outlet opening to one another, and at least one secondary flow channel as a means for creating an oscillation of the fluid flow at the outlet opening.
  • the direction from the inlet opening to the outlet opening can be regarded as the main flow direction of the fluid flow.
  • the main flow channel and the at least one secondary flow channel are separated from one another by at least one inner block, so that the main flow channel, the at least one inner block and the at least one secondary flow channel are arranged essentially in one plane.
  • the exiting fluid flow then oscillates in a plane of oscillation that corresponds to the plane defined by the main flow channel, the at least one inner block and the at least one side flow channel.
  • the flow chamber can have two secondary flow ducts which lie in one plane with the main flow duct, the main flow duct (viewed transversely to the main flow direction) lying between the two secondary flow ducts.
  • each bypass duct is separated from the main flow duct by at least one internal block.
  • the secondary flow channels can each have an input and an output via which they are fluidically connected to the main flow channel.
  • the boundary wall can have at least one section that is deformable.
  • the at least one section can have different material properties compared to the rest of the boundary wall, such as material thickness or extensibility (elasticity).
  • the at least one deformable section of the boundary wall can then be deformed under the targeted action of an external force.
  • a targeted action of an external force is not to be understood in particular as the pressure of the fluid flowing through the fluidic component. Rather, a device for exerting the external force can be provided, which can be actuated by a user. This also applies to the other embodiments.
  • an internal force which essentially results from the pressure of the fluid flowing through the fluidic component, can be used to deform the at least one deformable (e.g. elastic) section of the boundary wall in a targeted manner .
  • the at least one deformable section can be designed in such a way that it can be reversibly deformed by the action of the internal force, i.e. it changes from a first to a second configuration when the mass flow at the inlet opening (the input pressure) increases and when the mass flow falls at the inlet port (of the inlet pressure) returns from the second to the first configuration.
  • the transition between more than two configurations or a stepless transition is also conceivable.
  • the mass flow-dependent deformation of the at least one deformable section of the boundary wall and depending on the specific position of the at least one deformable section in the flow chamber and in particular at the outlet opening can be used to set an almost constant pressure or volume flow.
  • the fluidic component can become a so-called self-regulating system that has an almost constantly high volume flow at the outlet opening despite the varying admission pressure or fluid inlet pressure and generates an almost constant droplet spectrum.
  • the spray angle of the exiting fluid flow can remain almost constant or decrease (increase).
  • the at least one deformable section of the boundary wall can be designed as an elastically deformable wall delimiting the outlet opening (transverse to the direction of fluid flow), which deforms when the fluid pressure at the outlet opening changes and the cross-sectional area of the outlet opening changes to such an extent that the resulting droplet sizes of the exiting Fluid stream are hardly dependent on the admission pressure, and that the pressure at the outlet port essentially returns to the previously prevailing level or remains at this level.
  • the Sauter diameter of the droplets of the exiting fluid flow decreases less sharply in comparison to an almost rigid, unchangeable system with increasing inlet pressure, or remains almost stable despite increasing inlet pressure.
  • the material of the at least one deformable section of the boundary wall should be selected in such a way that it does not deform at any pressure of the fluid flowing through the fluidic component, which exerts the so-called internal force on the at least one deformable section, but only at a predetermined pressure Pressure range or pressure change range.
  • the fluidic component according to the invention can be used for various applications in which, on the one hand, the dimensions of the fluidic component and, on the other hand, the volume flow to be provided at the outlet opening can vary to a greater or lesser extent. The narrowest point of the fluidic component through which a flow can flow plays a particularly important role in the dimension.
  • the narrowest point through which a fluidic component can be flowed is the point (outside the bypass channels) at which the fluidic component has its smallest cross-sectional area, which extends essentially transversely to the fluid flow direction.
  • the narrowest point can be formed by the inlet opening, the outlet opening or by a point in the main flow channel at which the distance (transverse to the fluid flow direction) between the inner blocks is smallest.
  • Fluidic components for cleaning, wetting, coating or rinsing applications can have a cross-sectional area of 0.005 mm 2 to 200 mm 2 at their narrowest point.
  • the narrowest point can have a cross-sectional area of 0.005 mm 2 to 5 mm 2 .
  • the fluidic component can have a narrowest point with a cross-sectional area of 0.01 mm 2 to approx. 30 mm 2 .
  • Typical inlet pressures for the fluid in this area of application are 0.25 bar to 16 bar above ambient pressure.
  • the at least one deformable section of the boundary wall can be arranged in such a way that it closes the inlet opening and /or limits the outlet opening or that it allows a movement of a movable part of the boundary wall, the movement leading to a change in the cross-sectional area of the inlet opening or the outlet opening.
  • the specific alignment of the movable part of the boundary wall can be used to determine whether the movement of the movable part of the boundary wall increases or decreases the cross-sectional area due to a deformation (stretching as a result of an increase in the inlet pressure) of the at least one deformable section.
  • the inner blocks may have at least one deformable section at or near the point in the main flow channel where the distance (transverse to the fluid flow direction) between the inner blocks is smallest, so that a change in the cross-sectional area of this point in the main flow channel is possible is.
  • the material used for this at least one deformable section (the boundary wall or the inner blocks) can be a material that can expand or compress according to the pressure changes in order to change the size of the cross-sectional areas.
  • the material should be so deformable that with a pressure drop around the Factor 100 increases this cross-sectional area by a factor of 10.
  • this cross-sectional area should increase by a factor of 10 (from approx. 0.75 mm 2 to approx. 0.075 mm 2 ). to reduce.
  • the extent of the change in the cross-sectional area depends in particular on the (partially pressure-dependent) drag coefficient of the fluidic component.
  • a self-regulating nozzle system can also be designed in such a way that with varying volume flows at the narrowest point (inlet opening, outlet opening or point in the main flow channel), which result from varying inlet pressures, the same pressure reduction takes place within the fluidic component.
  • the cross-sectional area (1 mm 2 ) increases by approx. 14% when the volume flow at the narrowest point increases from 1.4 l/min to 1.6 l/min.
  • elastically deformable sections of the boundary wall or the inner blocks can be used.
  • an increased (internal) force can act on the boundary wall and the inner blocks. This force causes a reversible (elastic) deformation of a section of the wall, which then causes a deformation of another section of the wall, depending on the operating principle.
  • a change in flow can also be achieved by adjusting the pressure loss coefficient.
  • the wall section delimiting the narrowest point can be designed such that it deforms this wall section elastically or reversibly depending on the increasing pressure, for example due to the elasticity (resilience) of the material.
  • the at least one deformable section of the boundary wall can form the at least one bypass channel in sections.

Changing the width of the orifice can result in a change in jet momentum and pressure drop across the orifice. By reducing the outlet width, the jet impulse can be increased while the internal pressure remains the same, which can lead to an increase in cleaning performance by focusing the jet force.
  • the axes of rotation can be provided as close as possible to the outlet opening.

  • a partition wall 171 can be provided in each case, which already separates the secondary flow channels 104a, 104b from the connecting channel 170 in the region of the openings 170a, 170b.
  • the position of the partition wall 170 can be changed by means of a mechanism that is not shown.
  • the component depth t of the fluidic component is shown as constant as an example. Alternatively, the component depth t cannot be constant.
  • an eccentric can be used instead of the axis of rotation. This makes it possible to reduce the connection between an angle change (e.g. the angle ⁇ or the angle ⁇ ) and a change in distance (e.g. the outlet width b EX or between the ends of the inner blocks 11a, 11b facing the inlet opening) or to change the angle, without changing the distance at the same time.
  • an angle change e.g. the angle ⁇ or the angle ⁇
  • a change in distance e.g. the outlet width b EX or between the ends of the inner blocks 11a, 11b facing the inlet opening
  • the movement of these parts can be coupled or independent of one another and can be simultaneous or staggered in time.
  • the speed at which the movement takes place can also be the same or different for the several parts.
