Definitions

  • the invention relates to a rotor nozzle for a high - pressure cleaning appliance having a housing which has at least one inlet tangentially opening into the housing and an outlet arranged on an end wall of the housing, on which a bearing with a pan - shaped, centrally perforated recess is arranged, and with a Housing arranged, having a through-channel and having a spherical end in the cup-shaped recess supporting nozzle body whose longitudinal axis is inclined to the longitudinal axis of the housing and is offset by the liquid flowing through the housing in a circulating movement, wherein the longitudinal axis of the nozzle body on a conical surface rotates and the nozzle body is supported with a contact surface at its periphery on a support surface, wherein downstream of the support surface on the wall of the housing a plurality of flow resistance elements are arranged in the circumferential direction at a distance from each other, each having a projecting into the interior impact surface for the impact of liquid.
  • a compact liquid jet revolving on a conical surface can be produced which, for example, can be directed onto a surface for cleaning purposes.
  • the inlet of the housing may be supplied with liquid under pressure from a high-pressure cleaner.
  • a nozzle body which is mounted only on one side of the pan-shaped recess and can move in the housing about the longitudinal axis of the housing, moreover.
  • the nozzle body has a passageway through which the liquid can pass through the perforated recess of the housing.
  • the longitudinal axis of the nozzle body is inclined relative to the longitudinal axis of the housing.
  • the nozzle body By virtue of the liquid entering tangentially into the housing, the nozzle body is pressed into the socket-shaped depression, which forms a bearing for the nozzle body, and at the same time the nozzle body is rotated about the housing longitudinal axis added.
  • the exiting liquid jet also describes the desired circular movement, so that when a comparable pressure with dot jet nozzles a relatively large area can be acted upon with liquid.
  • the supply of the pressurized fluid over the tangentially into the housing opening inlet ensures that fluid in the housing is rotated about the longitudinal axis of the housing and thereby rotates the nozzle body to the housing longitudinal axis by within the housing a rotating liquid column formed.
  • the nozzle body has a very high rotational speed about the longitudinal axis of the housing, this can result in the liquid jet emerging from the outlet fanning out and thereby reducing the cleaning effect of the liquid jet occurring on a surface.
  • the flow resistance elements are formed by fins, which are arranged at the upstream end of an insert insertable into the housing.
  • the insert is slidable in the longitudinal direction of the housing and has at its upstream end a plurality of slot recesses, which form the lamellae between them.
  • the lamellae each form a baffle surface for the liquid flowing around, wherein the baffle surface is directed opposite to the liquid.
  • the rotational speed which the nozzle body has in its rotation about the housing longitudinal axis is indirectly reduced by the flow resistance elements arranged on the inside of the housing in that the flow resistance elements act on the circulating liquid in a slower manner. It is desirable to limit the speed of the nozzle body as effectively as possible during its rotational movement about the housing longitudinal axis.
  • the startup behavior is understood to mean the start of the rotation of the nozzle body about the housing longitudinal axis.
  • the nozzle body Before the housing is supplied under pressure fluid, the nozzle body is relative to the housing at rest, so he does not perform any circulation movement around the housing longitudinal axis. If pressurized fluid is now supplied via the at least one tangential inlet, then the nozzle body must reliably be set in rotation. If the nozzle body then carries out the rotational movement, then the rotational speed of the nozzle body should not exceed a maximum rotational speed in order to avoid fanning of the liquid jet emerging from the outlet.
  • Object of the present invention is therefore to develop a rotor nozzle of the type mentioned in such a way that the speed which has the nozzle body in its rotational movement about the housing longitudinal axis, can be effectively limited without the startup behavior of the nozzle body is significantly affected.
  • each baffle surface based on the flow direction of the liquid immediately upstream a guide surface to which the baffle surface connects continuously, wherein the guide surface oriented obliquely to a radial plane with respect to the longitudinal axis of the housing is.
  • each baffle surface is preceded by a guide surface, to which the respective baffle surface continuously adjoins in the flow direction of the liquid.
  • the baffles are oriented obliquely to a radial plane with respect to the longitudinal axis of the housing.
  • the oblique orientation of the guide surfaces has the consequence that circulating liquid is supplied along the guide surfaces to the baffles, which counteract the circulation movement of the liquid.
  • a significant slowing of the liquid flow can be achieved, and this in turn has the consequence that the speed that the nozzle body has during its rotational movement about the housing longitudinal axis, can be effectively limited.
  • the flow resistance elements are arranged downstream of the support surface on which the nozzle body is supported on the inner wall of the housing. In the region between the at least one inlet of the housing and the support surface no flow resistance elements are arranged, which could affect the movement of the liquid. This ensures that the start-up behavior of the nozzle body is not noticeably impaired despite the use of the baffle and guide surfaces.
  • the speed can be limited by the use of the baffles and guide surfaces, which has the nozzle body in its orbital movement about the housing longitudinal axis, but it can also be kept low, that is, the rotation of the nozzle body, which has the nozzle body about its own longitudinal axis.
  • the liquid rotating in the housing not only causes the nozzle body to rotate around the housing longitudinal axis in accordance with the liquid. Rather, the nozzle body is driven in particular in its front, the cup-shaped recess immediately adjacent area of the circulating liquid to a rotation about the longitudinal axis of the nozzle body.
  • the self-rotation about the longitudinal axis of the nozzle body is superimposed on the orbital motion of the nozzle body on the conical surface of the housing.
  • the self-rotation has the consequence that the fluid jet flowing out of the nozzle body also gets into rotation about its longitudinal axis. This leads to an additional fanning of the liquid jet, which impairs its cleaning effect.
  • the positioning of the baffle and baffle surfaces downstream of the support surface against which the nozzle body rests against the wall of the housing results in a slowing down of the orbital motion of the liquid jet, particularly in the region of the nozzle body, in which the nozzle body is excited by the liquid jet to self-rotation. It can therefore be limited by the use of the baffles and fins not only the speed of the nozzle body in its orbital motion to the Housing longitudinal axis, but it can also be limited to the speed of self-rotation of the nozzle body.
  • the baffles counteract the circulation movement of the liquid.
  • the baffles are at least partially disposed in a radial plane relative to the longitudinal axis of the housing.
  • the circulating around the housing longitudinal axis liquid can thereby impinge perpendicular to the baffle at least in a region of the baffle and thereby experience a particularly strong deceleration.
  • the guide surfaces are arcuately curved at least in certain regions.
  • the guide surfaces are convexly curved at least in regions outwards, that is, in the direction away from the longitudinal axis of the housing.
  • the arcuate curvature leads to a particularly effective flow change of the liquid in the direction of the baffle surface immediately following the respective guide surface.
  • Each guide surface in combination with the baffle surface adjoining the guide surface, favorably forms a channel-shaped widening of the interior of the housing.
  • the channel-shaped extension extends in the direction of the outlet of the housing.
  • the channel-shaped extension is aligned obliquely to the longitudinal axis of the housing, in particular parallel to the longitudinal axis of the nozzle body.
  • each guide surface forms in combination with the adjacent to the guide surface baffle in one oriented perpendicular to the longitudinal axis of the housing level of an S-shaped or sawtooth contour. It has been found that a particularly effective slowing down of the liquid flow in a region between the support surface, on which the nozzle body is supported, and the outlet of the housing can be achieved.
  • the baffle extends in the circumferential direction of the housing conveniently over a larger area than the adjoining baffle. It is particularly favorable if the guide surface extends in the circumferential direction over an area that is at least twice as large as the impact surface following the guide surface. The liquid is thereby supplied over a relatively large peripheral region in each case a baffle and then effectively braked at this.
  • the flow resistance elements are formed in a wall of the housing.
  • the flow resistance elements form in such a configuration together with the housing of a one-piece component.
  • the flow resistance elements in combination with the housing form a one-piece injection-molded part, which is preferably made of a plastic material.
  • the flow resistance elements are formed by an insertable into the housing insert.
  • the housing may be formed relatively thin-walled, wherein it may have on its inside a relatively smooth surface without profiling.
  • the risk of cracks forming in the housing when the housing is subjected to high-pressure liquid can thus be kept to a minimum.
  • the insert can form a prefabricated unit that can be inserted into the housing. The insert thus forms an additional component that provides the flow resistance elements, without thereby affecting the mechanical strength of the housing.
  • the insert part has a constant wall thickness along its circumference. This facilitates the shaping of the insert part in an injection molding process.
  • the insert part has in such a configuration on its outer side a contour corresponding to the inside contour of the insert part.
  • the insert is rotatably connected to the housing and immovable axially connected.
  • the insert leads in such a configuration, in spite of its braking action, which it exerts on the circulating liquid, neither a rotational movement nor an axial movement relative to the housing. Such relative movements could lead to damage of the insert part and / or the housing.
  • the provision of a rotationally fixed and axially immovable connection between the insert part and the housing thus allows a longer life of the rotor nozzle.
  • the insert is screwed to the housing and it has a stop surface, which rests in the end position of the insert on an inner shoulder of the housing.
  • the insert can be screwed so far into the housing in such an embodiment of the invention until it rests with its stop surface on an inner shoulder of the housing. A further rotational or axial movement of the insert relative to the housing is then no longer possible.
  • the insert part comprises an external thread which cooperates with a first internal thread of the housing.
  • the external thread of the insert is conveniently located downstream of the flow resistance elements.
  • the housing has, upstream of the cup-shaped depression, a complementary internal thread to the external thread of the insert part.
  • the screwing of the insert is identical to the circulation movement of the liquid within the housing.
  • the in the case circulating liquid thus pushes the insert in the end position in which the insert rests with its stop surface on the inner shoulder of the housing.
  • the circulating liquid thus ensures that the screw connection between the insert part and the housing can not be accidentally released.
  • the internal thread of the housing is preferably designed to be more continuous. This has the advantage that the insert part for producing a stable screw connection has to be twisted only slightly relative to the multiple thread. For example, it can be provided that the insert part has to be rotated by less than 360 ° relative to the housing in order to reach its end position.
  • pressurized fluid is supplied to the inlet of the housing during use of the rotor nozzle.
  • the rotor nozzle can have a connection part which can be connected to the housing for connection to a liquid supply line.
  • connection part is rotatably connected to the housing.
  • the connector advantageously has an external thread which can be screwed into a second internal thread of the housing.
  • the direction of rotation of the second internal thread coincides with the direction of rotation of the first internal thread.
  • a matching direction of rotation of the two internal threads facilitates the shaping of the housing and allows a particularly cost-effective production.
  • the direction of rotation of the second internal thread is opposite to the direction of rotation of the first internal thread.
  • the screwing-in direction of the insert part corresponds to the circulating movement of the liquid within the housing.
  • the Insert is thereby pressed by the liquid in its end position.
  • the reaction force of the housing does not lead to a loosening of the screw connection between the housing and the connecting part, the direction of rotation of the second internal thread is favorably opposite to the direction of rotation of the first internal thread.
