Definitions
- High-pressure cleaners especially for cleaning dirty stone or wooden floors, are now widely used in normal households. Such high-pressure cleaners are used in particular for cleaning dirty surfaces.
- garden pond cleaners or swimming pool cleaners are known in the prior art, for example, which are used for cleaning garden ponds or swimming pools. These known cleaners are connected to a tap of the normal domestic water supply via a hose. These well-known swimming pool and garden pond cleaners work with the principle of negative pressure. The inflowing tap water is fed into the cleaner in such a way that a negative pressure is generated and the dirt or sludge is sucked in from bottom to top. The sucked-in water-dirt mixture can then be pressed into a filter bag. In these known cleaners, however, it is disadvantageous that the suction power is too low because the water pressure in the water pipe is not high enough.
- the nozzle device is constructed in such a way that it comprises a first nozzle and a second nozzle.
- the nozzles are each connected to a high pressure line.
- the two nozzles are arranged relative to one another in such a way that the nozzle openings of the nozzles are directed in different directions. It can thereby be achieved according to the invention that the one nozzle is directed downward, for example, so that dirt can be loosened from underwater surfaces with this nozzle and through the second nozzle directed in another direction
- a negative pressure can be generated, so that the dirt can be sucked in and removed, for example, via a line.
- the use of high pressure ensures that, in addition to being suitable for soiling, a large negative pressure can also be generated in order to be able to reliably suck in dirt, etc.
- the nozzles are preferably oriented essentially opposite one another. This enables a particularly simple structure to be achieved.
- the nozzles are particularly preferably oriented opposite one another by approximately 180 °. It should be noted that a deviation from the value of 180 ° is possible in a range of approximately ⁇ 15 ° without relevant functional impairments occurring.
- the regulation of the nozzle or of the two nozzles takes place in each case via a regulating screw.
- This rule screw can be adjusted manually.
- the regulating screw is particularly preferably designed such that, in particular, it can completely close the pressure nozzle, which serves to loosen the dirt. If, on the other hand, the suction nozzle is completely closed by means of a regulating screw, the nozzle device works like a conventional nozzle of a high-pressure cleaner and can also be used over water like a conventional high-pressure cleaner.
- the nozzle device is preferably arranged in a housing comprising a first part and a second part.
- the first part is connected to the second part by means of an articulated connection.
- the housing or the two parts of the housing can be arranged at a certain angle to one another, so that corners or inclined planes in particular can be easily cleaned and vacuumed.
- the articulated connection is particularly preferably designed as a bellows.
- the two nozzles have different nozzle diameters.
- the filter device is preferably arranged in the suction path in front of the nozzles in order to prevent the nozzles from becoming blocked by large-volume or large-area dirt particles.
- the nozzle device according to the invention can be used in particular for retrofitting or as an adaptive additional element for high-pressure cleaners.
- Corresponding connections for the high-pressure cleaner must simply be formed so that the additional element with the nozzle device can be used to convert it into a combined suction-high-pressure cleaning device if necessary.
- threaded connections or snap-in connections can be provided as simple connecting elements to the high-pressure cleaner.
- the nozzles of the nozzle device are preferably provided interchangeably, so that if one nozzle is damaged, only the nozzle has to be replaced.
- a high-pressure cleaner is also provided with a nozzle device as described above, which, in particular if it is designed with a cleaning or suction nozzle with different diameters or with two adjustable nozzles, is used both as a normal high-pressure cleaner and as an exclusive suction cleaner or as a combined cleaning-suction system. Device can be used.
- Fig. 2 is a schematic, partially sectioned perspective view of a nozzle device according to a second embodiment of the present invention.
- the nozzle device 1 further comprises a housing which consists of a first, essentially cylindrical part 7 and a second, funnel-shaped part 8.
- the two parts 7 and 8 of the 'housing are articulated by means of a bellows 9.
- the second part 8 can be aligned at a certain angle to the first part 7.
- the nozzles 2, 3 are immovable themselves, the suction direction can be varied with the funnel-shaped part 8 of the housing at a certain angle.
- the funnel shape also supports the suction process.
- the nozzles 2, 3 it is also possible for the nozzles 2, 3 to be firmly connected to the housing part 8 and to be adjustable accordingly.
- a threaded connection 10 is provided on the first part 7 of the housing, in order to connect a hose or the like, for example, in order to be able to discharge the sucked-in liquid or the sucked-in dirt.
- the function of the nozzle device 1 according to the invention is as follows.
- a high-pressure fluid is fed into the connecting piece 4 via the high-pressure line 5.
- the fluid can be discharged through both the first nozzle 2 and the second nozzle 3.
- a jet is generated by the part of the high-pressure fluid discharged via the first nozzle 2, which jet is directed downward, for example to loosen dirt from a swimming pool floor by the jet directed downward.
- the other part is guided upwards via the second nozzle 3, so that a negative pressure is created in the region of the funnel-shaped second part 8 of the housing, so that dirt or water laden with dirt can be sucked in.
- a larger or smaller part of the high pressure fluid supplied can be passed through the first nozzle 2.
- the connection to the first nozzle 2 is interrupted, so that the complete fluid flow is discharged through the second nozzle 3.
- a suction effect is achieved on the second part 8 of the housing.
- Naturally Liche nozzle orifices of the first nozzle and the second nozzle 2 can 3, predefined, different volume flows can be achieved by the two nozzles 2, 3, which can be optimized by the control screw 6 by gentle predetermined difference ⁇ .
- FIG. 2 A second exemplary embodiment of a nozzle device according to the invention is described below with reference to FIG. 2. The same or functionally the same parts are designated with the same reference numerals as in the first embodiment.
- the two nozzles 2, 3 and the connecting piece 4 are arranged in the upper first part 7 of the housing. As a result, an adjustment of the housing part 8 is not hindered by the nozzle device.
- an exchangeable brush device 11 is provided at the lower end of the second part 8 of the housing, which is arranged around the entire outer circumference of the second part 8. Furthermore, a grid 12 is provided as a filter device on the second part 8 to large-volume or large-area parts such. B. to hold leaves or the like.
- the function of the nozzle device 1 according to the second exemplary embodiment corresponds to the first exemplary embodiment, so that reference can be made to the description given there.
- the present invention relates to a nozzle device for a high-pressure cleaner with a first nozzle 2 and one second nozzle 3.
- the first nozzle 2 and the second nozzle 3 are connected to a high pressure line 5.
- the first nozzle 2 is preferably arranged opposite the second nozzle 3 by approximately 180 °.
