Definitions
- the invention relates to a dishwasher with a washing container in which at least one Spray arm is arranged in the washing container by at least approximately vertical Axis is rotatably mounted.
- the spray arm is equipped with spray nozzles, which have a Circulation pump to be fed with rinsing liquid.
- spray arms which are designed such that they in particular Consider problem areas in the washing container.
- EP 0 974 302 a dishwasher for a dishwasher, which has a spray arm, the has corner nozzles, which are fed separately and only in defined Rotary positions of the washing or rinsing arm can be acted upon with rinsing liquid.
- the spray arm on a subdivided chamber system wherein the one Main spray nozzles are supplied with rinsing liquid, and wherein the other chamber, the Ecksprühdüsen supplied with rinsing liquid.
- the separate supply takes place via separate outlet openings in the hub region of the mounted spray arm, wherein defined in Rotary positions of the spray arm, the second chamber in flow communication for feeding the Ecksprühdüsen stands.
- the invention thus poses the problem of the efficiency of a spray arm to improve spray nozzles, in particular the spray jets higher Cover the washroom should give.
- the achievable with the invention advantages are that the use of the Pressure in the spray arm (for example, influenced by the change in the circulation pump speed) and the concomitant geometry change requires no additional actuators, which is achieved in particular by elastic means in the area of the spray arm are provided, due to the variable pump pressure different positions for Activation or deactivation of arranged on the spray arm spray nozzles.
- the elastic means for controlling in addition to Spray arm provided spray nozzles and / or Sprüharm Symposium Berlinen be provided.
- the elastic means are designed as spring elements, either an immediate Closure or opening of the nozzle opening effect, or that they are in operative connection with pivotable or displaceable arm areas are, for activation or Deactivation of these arm areas, respectively the spray nozzles.
- the spring element may be formed as an elastic molded part, which as a result the pressure increase the opening cross-section of the nozzle releases, the other way round due to the Pressure reduction an automatic closure by the elastic molded part again is caused.
- the elastic molding of a lip-like Ring element consist, which as a result of its elastic recovery in pressure drop to Closing the nozzle opening leads.
- the elastic molding as Membrane designed to deform only at a certain pressure.
- An at the Diaphragm-mounted slider ensures that when deformed membrane an additional Nozzle, which was previously closed, is released again. Further advantages of this solution it is that, irrespective of the diaphragm, the or switch off and an intensive flushing zone is generated without additional actuators for Spray jet change are required.
- the spray jet variety the selected program can be specified or changed accordingly.
- the spring element comprises a return spring, which cooperates with a displaceably mounted closure element which covers the opening cross-section of the nozzle.
- the return spring does the same job, such as the membrane.
- a return spring cooperates with a sliding arm mounted on the spray arm, which covers a plurality of nozzles or releases them again when the pressure increases.
- a return spring cooperates with a free, displaceably mounted end region of the spray arm, so that a change in length of the spray arm is caused, which in particular by centrifugal force, also caused by pressure increase, can be caused.
- the return spring interacts with pivotally mounted additional spray arms on the main spray arm, wherein the return spring pivots the additional spray arm at a certain speed back to its original position. If the speed is increased by increasing the pressure of the spray arm, the corresponding additional spray arms swing out and thus cover additional areas in the spray room.
- the subject invention relates to a dishwasher, which does not detail in detail in which a washing container is provided, in which at least one spray arm. 1 is arranged, which is rotatably mounted in the spray chamber about a vertical axis 2, wherein the spray arm 1 is equipped with spray nozzles 3 and 13, which also has no closer shown circulating pump to be fed with rinsing liquid.
- the activation or deactivation of special components on Spray arm 1 shown within a drawing.
- the nozzles 13 are permanently open.
- the elastic means 4 are provided, which due to the variable pump pressure a first closed, and a second open position, to take in this way, provided on the spray arm 1 spray nozzles. 3 either to activate or deactivate.
- the elastic means 4 can thus for Control of additional provided on the spray arm 1 nozzles 3 and / or Sprüharm Societyen be provided.
- the elastic means 4 as spring elements formed, either an immediate closure or opening of the nozzle opening effect (see Figures 1, 2, 3, 4 and 5) or in operative connection with pivoting or slidable arm areas (see Figures 6, 7, 8, 9 and 10) are, for activation or for Deactivation of these arm areas, respectively the spray nozzles 3.
- Figure 1 and 2 shows a spring element, as an elastic molding is trained.
- a slider 5 acts with a Membrane 6 together, so that due to the pressure increase in the spray arm 1, the membrane 6 after 1 b, and thus in particular the slider 5 from the opening of the Pull the spray nozzle 3 away.
- the membrane pushes 6 the slider 5 back to the opening of the spray nozzle 3, as shown in the figure 1a is.
- Another embodiment of the opening or self-closing due to the changing pressure is shown in the figure 2a, 2b, wherein in the region of the nozzle opening.
- FIGS. 3a and 3b show another embodiment, which corresponds in the operation of the embodiment of Figure 1 a, 1 b, wherein in this Embodiment, the spring element comprises a return spring 9, with a displaceable mounted closure element 10 cooperates, which also has the opening cross-section the nozzle 3 either releases or closes, as in the synopsis of Figure 1 to recognize.
- the movement of the Closure element 10 not directly by the prevailing in the spray arm 1 water pressure, but on the dependent on the rotational speed of the spray arm 1 Centrifugal force. As the speed of the spray arm 1 but also directly from the pump pressure is dependent on an activation of the nozzle 3 by influencing the Pump pressure done.
- FIG. 6a and 6b Another variant of the invention is the figure 6a and 6b, wherein a return spring 29th with a freely slidably mounted end portion 11 of the spray arm 1 cooperates. It It goes without saying that if, due to the increasing centrifugal force, the Return spring 29 is stretched and the end portion 11 then against the force of Return spring 29 moves, so that the spray arm 1, shown in Figure 6a, extended is detected and in this way the spray arm 1 an extended area in the washing.
- FIGS. 7, 8, 9 and 10 show in particular further embodiments of the invention, it is the characteristic of these embodiments that not shown here Return springs with pivotally mounted additional spray arms 12 on the main spray arm 1 work together.
- the figure 7a and 7b on the portions of the main spray 1 in each case a Hilfssprüharm 12.1 and 12.2, because of the inner added weight 16 pivots due to increased rotational speed, shown in Figure 7b and 8a, and at low pump pressure and associated reduction in the Sprüharm beau is pivoted in an inactive position, as shown in Figure 7b is shown.
- FIG. 8a illustrates that both in the spray arm 1 and in the Hilfssprüharmen 12.1 and 12.2 each have an opening cross section 14 and 15 in the form a quarter circle is arranged.
- FIGS 9 and 10 show further embodiments according to the figure 7a, 7b, wherein here freely mounted Hilfssprüharme 12 are arranged, which individually or in angular position to each other are arranged pivotably on the main spray 1. These Hilfsssprüharme 12 act against the force of a spring, wherein the supply is also dependent on the pump pressure.
- the pump pressure such to adjust that the generated force is just able to the activatable nozzles 3 to to open.
- the volume flow decreases through the Nozzles 3 and 13 and thus the pressure of the liquid, whereby the nozzles 3 closed again become.
- the pressure is increased again, which in turn Opening the nozzles 3 leads.

Abstract
Description
Auch ist es denkbar, dass die Rückstellfeder mit schwenkbar gelagerten zusätzlichen Sprüharmen am Hauptsprüharm zusammenwirkt, wobei die Rückstellfeder den zusätzlichen Sprüharm bei einer bestimmen Drehzahl wieder in seine Ausgangslage zurück verschwenkt. Wird die Drehzahl durch Druckerhöhung des Sprüharmes erhöht, schwenken die entsprechenden zusätzlichen Sprüharme aus und überstreichen somit zusätzliche Bereiche im Sprühraum.
