Definitions
- the invention relates to a pane wash nozzle for producing at least two nozzle jets for cleaning a vehicle pane, in particular for cleaning the windshield or rear window.
- a pane wash nozzle is shown, for example in EP 2 144 702 B l .
- a nozzle chip which has a plurality of openings for different spray jets is present there. If the spray pattern of such a nozzle is intended to be asymmetrical, different nozzle chips are necessary for the driver's side and front passenger's side.
- the object is achieved by a pane wash nozzle for a motor vehicle, wherein the pane wash nozzle has a liquid inlet, an insert body with a first nozzle opening predominantly formed by the insert body, and an insert body holder into which the insert body is insertable or inserted in a receptacle, wherein the insert body holder has a second nozzle opening predominantly formed by the insert body holder.
- the object is furthermore achieved in particular by a method for producing a pane wash nozzle, containing the following steps:
- the pane to be cleaned with the pane wash nozzle can be, for example, a windowpane (for example windshield), a headlight lens or a camera lens of the vehicle.
- the pane wash nozzle is preferably designed as a compact module.
- one pane wash nozzle is provided for the driver's side and one for the front passenger's side of the windshield.
- the motor vehicle preferably has one pane wash nozzle for the driver's side and one for the front passenger's side of the windshield.
- the pane wash nozzle is preferably suppliable with washing liquid via the liquid inlet.
- a hose of the washing liquid system of the vehicle is connected to the liquid inlet.
- An insert body is known in the prior art. It is preferably a nozzle chip, and the insert body holder is then correspondingly a nozzle chip holder.
- a structure for producing an oscillating liquid jet is frequently introduced in the prior art, and this is preferably also the case here.
- the predominantly formed component forms the largest portion of the border of the nozzle opening.
- the first nozzle opening of the insert body can be formed predominantly by the insert body and at the same time, but not predominantly, by the insert body holder, wherein the insert body forms three sides of the opening and/or the opening edge over a circumferential angle about the opening center point of more than 180°, while the insert body holder forms only one side and/or less than 180° of the opening edge.
- the nozzle opening is a nozzle opening of the insert body.
- a nozzle opening is preferably understood as meaning an outlet opening which forms the end of a liquid channel of the pane wash nozzle, after which outlet opening the liquid then leaves the pane wash nozzle as a whole.
- the liquid preferably exits from the nozzle opening into the open air.
- the first nozzle opening is preferably a nozzle opening for producing a fan jet, in particular a fan jet produced by an oscillating jet.
- the second nozzle opening is preferably a nozzle opening for producing a spot jet.
- spot jet here should be understood relative to a fan jet and not exclusively ideally physically.
- the first and second nozzle opening are preferably arranged on a same end side of the pane wash nozzle, wherein the end side then expediently faces the pane to be cleaned.
- the insert body holder is preferably mountable onto the vehicle. It preferably has an adjustment device, for example an adjustment mechanism, by means of which it is mountable adjustably on the vehicle.
- an adjustment device for example an adjustment mechanism, by means of which it is mountable adjustably on the vehicle.
- the liquid inlet it preferably has a liquid outlet. From the liquid inlet (and outlet, if present) there is a duct system which diverts liquid to the two nozzle openings.
- the second nozzle opening is partially bounded by an outer side of the insert body.
- the second nozzle opening can advantageously be formed in the insert body holder, in particular by means of injection molding.
- the insert body holder has a shaft as receptacle, and a liquid duct leading to the second nozzle opening is formed on an inner wall of the shaft.
- the shaft preferably has an inner contour corresponding to the outer contour of the insert body in such a manner that the insert body can be inserted into the shaft.
- the insert body is preferably fixable in the shaft by means of an interference fit.
- the liquid duct preferably runs outside the insert body and connects the second nozzle opening fluidically to the liquid inlet.
- the liquid duct is preferably at least partially bounded by an outer wall of the insert body.
- the liquid duct is formed as a groove in the inner wall.
- the groove preferably extends in the longitudinal direction of the shaft.
- the insert body holder has a liquid branching-off portion by means of which two separate liquid flows can be produced, one to the first nozzle opening and another to the second nozzle opening.
- the liquid branching-off portion is preferably formed by two separate passages in the shaft of the insert body holder, preferably passages through the bottom region of the shaft.
- the insert body holder with the second nozzle opening has a symmetrical configuration such that it is useable both for cleaning on the driver's side and for cleaning on the front passenger's side of the motor vehicle, and a spray pattern, which is symmetrical with respect to the center axis between driver's side and front passenger's side, of the second nozzle opening is produced.
- the insert body holder is useable more universally.
- the symmetrical design is preferably present by the insert body holder being axially symmetrical to a horizontal axis, wherein, in the state installed in the vehicle, the horizontal axis is oriented parallel to the y axis according to the system of co-ordinates of the vehicle.
- the center axis between driver's side and front passenger's side preferably lies in the x-z plane according to the system of co-ordinates of the vehicle.
- the pane wash nozzle and/or the spray pattern thereof is preferably symmetrical to a preferably horizontal axis, parallel to the y axis and asymmetrical to a preferably vertical axis which is perpendicular thereto and is parallel to the z axis.
- the receptacle has a height h which, in the state installed in the vehicle, is substantially perpendicular to the plane of the carriageway, and the second nozzle opening is arranged at half of the height h.
- the insert body has the first nozzle opening preferably centrally with respect to the insert body width, wherein the insert body width is oriented perpendicularly to the height h of the receptacle.
- the first nozzle opening is preferably arranged on the upper or lower edge of the insert body eccentrically with respect to the height of the insert body, wherein the height of the insert body is oriented parallel to the height h of the receptacle. This eccentric arrangement is advantageous in particular if the first nozzle opening is intended to produce an oscillating jet since the structure necessary for this purpose can then be simply formed on the upper side and/or lower side of the insert body.
- perpendicular to the plane of the carriageway is preferably the z direction according to the system of co-ordinates of the vehicle.
- the insert body holder is injection molded, and, during the injection molding process, the second nozzle opening is formed by the injection molding die.
- the insert body holder is injection molded, and, after the injection molding, the second nozzle opening is formed in a subsequent material removal step.
- This achieves great production flexibility since it is possibly intended for not all of the pane wash nozzles to obtain a second nozzle opening and this can be decided by omitting or carrying out the material removal step.
- the second nozzle opening is preferably completely formed in the material removal step.
- the second nozzle opening is particularly preferably already preformed during the injection molding, for example a material weakening is introduced at the future location of the second nozzle opening, and then the second nozzle opening is finally formed by means of the material removal step.
