Definitions
- the present invention relates to a dishwasher according to the preamble of claim 1.
- a dishwashing machine with pulsating nozzles wherein an arm has a plurality of nozzles which are supplied to one another via different channels.
- a channel is in connection with so-called auxiliary nozzles, wherein the supply of rinsing liquid to these auxiliary nozzles can be shut off via a valve. This ensures that the rinsing liquid exits pulsating and partially the spraying of rinsing liquid from the iö auxiliary nozzles is avoided.
- a dishwasher with a spray arm is known in which individual spray nozzles can be activated or deactivated without the use of additional actuators. Depending on the change in the pump pressure, a pulsation of the spraying of the dishes can be achieved in order to allow effective cleaning.
- elastic means are provided which can open and close the individual nozzles.
- the spray jet in the prior art nozzles always exits according to the nozzle opening. It is not intended that the spray jets be changed in geometry and therefore may not enter well in problem areas such as pots, sink corners or other hard to reach areas. Because despite the
- At least one spray arm is used, in which a rotating element generates pulsating spray jets in the interior.
- the present invention poses the problem of providing a dishwasher in which the exiting rinsing liquid in the spray jet can be at least partially adapted from simply constructed spray arms.
- a dishwasher having the features of claim 1.
- a flow obstacle for changing the geometry of the spray jet is provided within the spray arm in front of at least one nozzle. It has been found that by a flow obstacle adjacent to the nozzle but within the spray arm, the geometry of the exiting spray jet can be changed so that it not only straight out of the spray arm, but also has other geometries, which increases the effectiveness of the cleaning performance. Because, in particular, by changing the geometry of the spray can also poorly accessible areas, as well as in pots or corners reach.
- the spray arm is formed as a hollow body and a flow obstacle is held on the opposite to the nozzle inner wall of the hollow body.
- defined flow channels are formed within the spray arm, so that the exiting fluid generates a spray jet in accordance with the design of the flow obstacle and the nozzle.
- the flow obstacle may protrude to just before the exit surface of the spray jet at the nozzle, for example in a range of less than 4 mm.
- the flow obstacle is movable relative to the adjacent nozzle.
- a plurality of nozzles are provided distributed over the spray arm, each associated with a flow obstacle.
- a suitable flow obstruction of the nozzle can be assigned depending on the seat of the nozzle.
- flow obstacles are advantageous, which produce a somewhat wider spray jet, while radially inner nozzles on the spray arm can produce a narrower, more powerful jet.
- the flow obstacle may preferably be formed as a pin with a rounded surface, so that there is a conical spray. It is also possible to form the flow obstruction as a V-shaped ramp, as a helix, or as a pin to produce a particular spray.
- FIG 1 is a sectional side view of an embodiment of a spray arm according to the invention
- FIGS. 2A to 2E show several detailed views of different flow obstacles for a spray arm
- Figure 3 is a sectional side view of a second embodiment of a spray arm according to the invention.
- Figures 4A and 4B show a detail view of the spray arm of Figure 3 with a flow obstruction in different positions;
- Figure 5 is a sectional side view of a spray arm according to a third
- Figure 6A is a detail view of a flow obstruction of the spray arm of Figure 5
- Figure 6 B is a detail view of a modified flow obstacle for a
- a spray arm 1 is arranged in a washing compartment of a dishwasher, not shown in more detail. It is designed as a hollow body 2 and provided centrally at a central opening with a connection 3 for connection to a pipe system of the dishwasher. Thus, rinsing fluid can be pumped into the spray arm 1 via a pump, also not shown.
- the connection 3 is arranged on a central axis of rotation A of the spray arm 1.
- nozzles 5 On the hollow body 2 a plurality of nozzles 5 are formed in a first wall 4, can be sprayed via the rinsing liquid not shown in detail ware. Furthermore, one or more drive nozzles 6 can be provided, which ensure a rotation of the spray arm 1 during the rinsing operation.
- the nozzles 5 may be directed upward as shown in the figures. Alternatively, downward orientation is also conceivable in order to clean dishes under the spray arm.
- flow obstacles 8 are arranged in the hollow body 2, which extend from the opposite wall 7 of the hollow body 2 in the direction of the nozzles 5.
- Each flow obstacle 8 is associated with a nozzle 5.
- FIG. 2A shows a nozzle 5 of a spray arm, as used in the prior art.
- the nozzle 5 is directed upwards and has an exit surface 9, through which the rinsing liquid emerges in a punctiform jet 10. Due to the volume flow, the jet 10 can be varied in intensity in flushing liquid, but not in the geometry. The beam shape thus remains the same.
- FIG. 2B shows the spray arm 1 according to the invention with the flow obstacle 8, which is designed as a journal and has a rounded surface, preferably a hemisphere, which is arranged adjacent to the nozzle 5.
- the flow obstacle 8 is arranged directly adjacent to the nozzle 5 in front of the circular exit surface 9, so that the flow of the rinsing liquid on the way into the nozzle 5 is influenced.
- the shape of a jet 11 is changed out of the nozzle 5, so that due to the peg-shaped flow obstacle 8, the jet emerges from the outlet surface 9 in a cone shape.
- This jet shape can cover a larger area, which is supplied with rinsing liquid.
- a modified flow obstruction 18 is arranged in the spray arm 1, which is designed as a thin pin projecting through the nozzle 5.
- a tip 19 is arranged outside the exit surface 9 of the nozzle 5.
- a spray jet 20 is formed, which is designed as a hollow cone. Due to the conical spreading of the beam, a relatively large spray area is covered on the one hand and on the other hand the volume flow in the region of the i 5 outer surface of the hollow conical jet 20 is greater than a full cone beam 1.
- a ramp is formed on the bottom 7 of the hollow body which extends in the form of a wall and is V-shaped adjacent to the nozzle 5, so that bevels 29 are formed which are directed toward the nozzle 5.
- the spray jet 30 emerging from the exit surface 9 is designed as a flat jet 20 which widened in a wedge shape.
- FIG. 2E shows a further embodiment of a flow obstacle 38, which is provided as a helix with a helical channel 39. This helix ends shortly before the exit surface 9 of the nozzle 5, so that the outgoing jet 40 is formed as a vortex jet.
- washing compartment of a dishwasher can be achieved.
- An adjustment is not provided in this embodiment, since the flow obstacles 8, 18, 28 and 38 are fixedly connected to the bottom 7 of the spray arm 1.
- a spray arm 1 is provided, which in turn is designed as a hollow body 2 with a central connection 3, wherein the connection 3 long of a central axis of rotation A is arranged.
- the hollow body 2 has in its upper wall 4 nozzles 5 and also one or more drive nozzles 6.
- nozzles 5 extends within the hollow body 2, starting from the opposite wall 7 each have a flow obstacle 8 'in the direction of a nozzle which is adjustable on the bottom 7 of the Low spray 2 s is maintained.
- the flow obstacle 8 ' is designed as a pin with a rounded surface, wherein on the pin 8' an external thread 9 'is formed, which is in engagement with a thread (not shown) on the wall 7. As a result, the flow obstacle can be moved closer to the nozzle 5 or away from the nozzle 5 by turning the pin 8 '.
- the hemispherical surface is arranged immediately adjacent to the nozzle 5, so that the flow path of the rinsing liquid 15 to the nozzle 5 is relatively strongly influenced so that the outgoing jet has a further fanned out geometry, as in the position shown in FIG.
- the user can adjust the geometry of the spray jet by manually screwing or unscrewing the pins 8 'on the spray arm 1'.
- FIG. 5 shows a further embodiment of a spray arm 1 according to the invention, which is designed as a hollow body 2 and has a connection 3 around a central axis of rotation 4.
- the hollow body 2 has a plurality of nozzles 5 distributed over the length, with drive nozzles 6 also being provided as a rotary drive.
- Adjacent to the nozzles 5 are provided as flow obstacles pins 8 "with a rounded surface, but these are not fixedly arranged on the nozzle 5 opposite wall 7 of the hollow body 2, but via a spring element 9" movable.
- the distance of the flow obstruction 8 "to the nozzle 5 is dependent on the pressure within the spray arm 1, so that with increased pump speed the flow obstacles 8" are pushed further away from the nozzle 5 than at low pump speed.
- the spray jet is varied from the nozzles 5 depending on the pressure within the spray arm 1.
- 5 shows the mounting of the flow obstruction 8 "shown in FIG. 5.
- the journal 8" is mounted on a helical spring 9 ", preferably made of steel, wherein the spring 9" bears against a receptacle 10 "on the wall 7 of the spray arm 1 "is supported.
- the flow obstacles 8 are either fixedly mounted on the bottom 7, adjustable on the bottom 7 or resiliently on the bottom 7. It is of course also possible to provide different flow obstacles 8 on a spray arm, which are partially fixed, partially adjustable and partially spring-mounted.
- the geometry of the flow obstacles within a spray arm can deviate, so that different borrowed geometries of spray jets at the individual nozzles 5 can be generated. In this case, instead of a circular exit surface on the nozzle 5, a slot hole or another geometry may be provided.
