WINDSHIELD CLEANER APPARATUS
DESCRIPTION The invention concerns an apparatus for glass cleaner with a fluidic nozzle body having a washing nozzle for spraying cleaning liquid sprayed and having a fitting for the connection of a liquid feed pipe of 1 imp. The glass cleaner apparatuses of the above class are used in current motor vehicles especially for windshield spraying and, therefore, are generally known. In known glass cleaning apparatuses, the body of the fluid nozzle is fixed to the body of the vehicle by means of retaining parts. It is disadvantageous to note here that the area of the body on which the body of the fluid nozzle is fixed has relatively large tolerances. This leads to the fact that the necessary exact orientation of the washing nozzle with respect to the glass is not always provided. This is especially disadvantageous in glass cleaning apparatuses in which the cleaning process is carried out by means of a simple spray with the cleaning liquid without a subsequent rubbing with a windscreen wiper, since in such systems the cleaning action requires a very exact spray of a liquid. determined area. Conventional washing nozzles are commonly configured as a spherical head which is seated in a spherical bowl of a washing nozzle holder and which can be oriented exactly with respect to the glass after its assembly. However, this configuration would be very complicated and expensive in fluidized nozzles that are increasingly diffusing, since they must have a relatively large fluidic nozzle body that is not configured with rotational symmetry. The invention is based on the problem of configuring a glass cleaner apparatus of the kind mentioned at the beginning so that it can perform as easily as possible an orientation of a body of the fluid nozzle. This problem is solved according to the invention because the connection has at least one retaining part for its invariable attachment to a part of the body and a spherical head at its end turned towards the body of the fluidic nozzle, and because the body of the nozzle fluidic is retained with a spherical cup on this spherical head in a sealing manner, but tiltable to all sides and rotating around its longitudinal axis in relation to the fitting. In a glass cleaner installation of this kind, the fitting is fixed to a part of the body instead of fixing the body of the fluid nozzle. This connection is connected to the body of the fluid nozzle by means of a ball joint. In this way, the body of the fluidic nozzle can be tilted to all sides and, moreover, rotate about its axis, which runs in the direction of the jet of ejected liquid. The latter is advantageous when the washing nozzle has an elongated spray field which must be oriented as accurately as possible in the main extension direction of a glass to be sprayed. The assembly of the glass cleaner apparatus can be carried out particularly quickly when the spherical cup is configured as an elastic mounting part that can be snapped onto the spherical head. This embodiment also makes it possible to rapidly swing the body of the nozzle outwards when, for example, a heating system provided in the same is defective. The heating system provided frequently in the present washing nozzles, by means of which freezing in case of frost is prevented, can be easily processed in the glazing apparatus according to the invention, making the body of the fluidic nozzle above its surface. spherical cup a cable channel with an electric cable and an electric heating element is provided inside the body of the fluidic nozzle above a fluidic element. The invention is illustrated in its preferred embodiment, in the single accompanying figure, showing in longitudinal section the apparatus of the invention. The drawing shows a fitting 1 having on one side retaining parts 2 for immovably fastening to a body part not shown. At its left end, seen in the drawing, the connector 1 has a cone 3 that serves to plug a hose, not shown either, intended to feed cleaning liquid. At its other end the fitting is provided with a spherical head 4. On this spherical head 4 a fluidic nozzle body 5 with a spherical cup 6 fits. This is of elastic configuration, so that the body 5 of the fluidic nozzle it can be plugged onto the spherical head 4 and remains retained by the elasticity on it with a sealing effect, but a tilting towards all sides and a rotation about the longitudinal axis of the fitting 1. In the body 5 of the fluid nozzle is possible. A fluidic element 7 is disposed. The cleaning fluid fed through the fitting 1 is sprayed from the body 5 of the fluidic nozzle by a washing nozzle 8. Within the body 5 of the fluidic nozzle flows over the spherical cup 6 a cable channel 9 through which a cable 10 extends to a heating element 11. In this way, electric heating of the washing nozzle 8 and the entire body 5 of the nozzle flow is possible Dica. Although the preferred way of carrying out the invention has been described, it is evident that different forms of execution can be made without departing from the scope of the invention, which should be contemplated in its broadest sense, limited only by the following clauses.
