Dispensing device for liquid and / or powder treatment agents for use in a washing machine, with at least one chamber (6.1) for storing the treatment agent, being arranged in the chamber (6.1) for storing the liquid treatment agent and / or powder an additional separate container (8) for storing an additional liquid treatment agent, which can be inserted into the chamber (6.1) forming a gap (9) between the wall (10) of the container and the wall (11) of the chamber, and with nozzles (7, 16) arranged above the chamber, through which water is conducted on the treatment agent, characterized in that the nozzles (7, 16) are divided into at least a first (7 ) and a second subset (16), the first subset of nozzles (7) being arranged in side sections above said chamber (6.1) and the second subset of nozzles (16) in a central section above said chamber (6.1 ) or of the container (8) inserted, and because the introduction of water through the first subset of nozzles (7) and the second subset of nozzles (16) can be selectively controlled, the first subset of nozzles (7) being directed toward the gap (9) to dispense the water in the chamber (6.1).
The invention relates to a dispensing device for liquid and / or powder treatment agents for use in a washing machine, with at least one chamber for storing the treatment agent, being arranged in the chamber for storing the liquid treatment agent and / or powder an additional separate container for storing an additional liquid treatment agent, which can be inserted into the chamber by forming a gap between the wall of the container and the wall of the chamber, and with nozzles arranged above the chamber, through from which water is conducted on the treatment agent.
A dispensing device of this type is known from US 2005/229652 A1. The dispensing device disclosed in this case has cameras for storing powder treatment agents. Additional dispensing containers are provided to dispense liquid treatment agents, which can be inserted into the chamber forming an interstitium with respect to the chamber wall. The liquid treatment agent remains in the container until, with the help of water introduced through nozzles from the upper side, it is ejected from the chamber and then led to the tank. For each chamber a set of nozzles is provided in each case, which spray the entire chamber with water, so that only one agent that must be used instead of the powder can be dispensed into the inserted container.
From US 2003/145633 A1 a dispensing device is known, which has cameras for storing powder treatment agents. For dispensing liquid treatment agents, additional cuvette-shaped containers are provided which, being inserted into the chambers, are bathed in place of the chamber.
In the prior art, detergent boxes are also known, which are equipped with a dispensing device. Through the dispensing device, running water is passed through the chambers of the box, so that the powdered detergent or liquid stored therein is dragged and mixed with the dispensed water, to be supplied to the washing process. This is known, for example by document DE 101 50 878 A1 or document DE 75 13 925 U1, a distribution drawer for a washing machine with different conduction channels, through which the different detergents can be extracted. Another embodiment of a detergent box is known from EP 0 685 587 A1, in which a reservoir is arranged in one of the chambers that can be reserved for storing a liquid bleaching agent.
Furthermore, according to DE 195 05 292 A1, a box for a detergent dispensing device, which also has several chambers, is known according to the state of the art, in which one of the chambers is designed to store the liquid detergent and acts together with a so-called siphon device, with which the liquid detergent can be extracted easily and safely. From DE 34 04 247 A1 a detergent dispensing device is known, in which the separation wall between two adjacent chambers has an additional fixed shaped chamber for liquid detergents.
The invention is based on the objective of providing a detergent dispensing device for use in a washing machine, which makes it possible to simply load and dispense additional treatment agents.
According to the invention, the objective is solved with the characteristics of independent claim 1. Advantageous configurations and improvements of the invention are obtained from dependent claims 2 to 10.
The advantage that can be achieved with the invention is that, in a chamber for storing a first liquid or powder treatment agent, for example detergent, at least two different treatment agents can be stored simultaneously. For this purpose, an additional separate container for storing an additional liquid treatment agent, for example a bleaching agent, is inserted into the chamber to store the detergent. To dispense the treatment agent, nozzles are arranged above the chamber, through which water is directed to the chamber or to the container on the respective treatment agent. For the dispensing of the treatment agent from the chamber, a first subset of nozzles is provided, which are arranged in lateral sections above the chamber. For dispensing the treatment agent from the separate container, a second subset of nozzles is provided, which are arranged in a central section above the chamber or the inserted container. The introduction of water through the first and second subset of nozzles can be selectively controlled, so that the dispensing of the respective treatment agent takes place depending on the stage within a washing program or treatment program.
For reliable dispensing, the container can be inserted into the chamber in such a way that a gap is formed between the wall of the chamber into the chamber. The subset of nozzles for dispensing the treatment agent from the chamber are directed towards the interstitium. Through the lateral gap between the container and the walls of the chamber, the nozzles of the first subset pass the water through the lateral walls and therefore laterally below the detergent.
In this way a clean expulsion is obtained, which takes place without caking the detergent.
In an advantageous embodiment, the nozzles are disposed above the gap directed inclined towards the chamber wall. The nozzles therefore spray the water on the wall of the chamber, so that it runs downwardly as a film through the wall of the chamber and, consequently, in the lower area of the chamber causes the treatment agent, by example powder detergent, bathe completely. The formation of the water film prevents adhesion to the chamber wall, since water continues to flow permanently through the first subset of nozzles until the chamber has been emptied. The first subset of nozzles is disposed in this regard in the dispensing device such that they are directed along the wall of the chamber.
In order to empty the container it is convenient that the second subset of nozzles be arranged essentially centered above the container. The container as such has in this respect a cover, which contains an elongated opening, through which water can also be injected for emptying through the dispensing device. The second subset of nozzles is located above this opening, to provide reliable dispensing of water into the container.
In an advantageous development, a pivotally arranged lid is provided for loading the container in the front area of the container.
In a convenient embodiment, the spacers are arranged on the outside in order to save the gap, a space being kept underneath the container, through which the treatment agent is expelled out of the chamber. This gives the container in the chamber a certain stable position, providing a complete bath essentially without dipping points and a reliable dispensing of the treatment agent from the chamber.
In an advantageous development, the separators are configured in cross-section, from the point of view of their shape, as a wing. This form influences the water flowing through them in that they avoid or at least reduce points not bathed in the separators, whereby caking and residual formation of powder treatment agents on the walls of the chamber are avoided or on the walls of the container.
In a further embodiment, the container has a device for virtually complete emptying. To this end, the bottom of the container has an inclined or domed shape, which ends at an end side with a siphon as the back wall of the container. If tap water is then applied to the container through the dispensing device, then a level that allows the fluid to enter the so-called drop tube for emptying is adjusted with respect to the siphoning device, so that the container is automatically emptied.
In a convenient embodiment, the container has on its outer wall means to fix its position inside the chamber. In this sense, it is convenient to arrange an interlocking means on the rear wall, which is locked in a certain position in an opening of the rear wall of the chamber, whereby the position of the container in the container is adopted and reliably maintained. longitudinal direction in the chamber.
An embodiment of the invention is explained in more detail by the following figures 1 to 7; in this regard they show:
Figure 1: a perspective representation of a washing machine with the box partially removed;
Figure 2: a top view of a box;
Figure 3: a perspective representation of the dispensing device;
Figure 4: a cross-sectional representation in its transverse extension of the dispensing device, along the line IV-IV in Figure 3;
Figure 5: A sectional representation of the dispensing device in its longitudinal extension, along the line V-V in Figure 3;
Figure 6: a detailed perspective representation of the container with the front lid open and
Figure 7: an additional perspective representation of the box with the container inserted without upper part.
Figure 1 shows in the perspective representation a fragment of a washing machine 1, a removable box 3a being arranged on the front side of the washing machine 1. The box 3a contains one or more chambers for storing treatment agents, a dispensing device 2 for dispensing the treatment agents from the chambers being arranged inside the washing machine 1. The box 3a of the dispensing device 2 is best represented in the detailed view of figure 2. Figure 3 shows the dispensing device 2 in perspective, a flat shaped upper part 3 being arranged above the box 3a. For the selective guidance of the water supply to the interior of the upper part 3 a controllable water distributor 4 is provided, which is preferably arranged on the rear side, directed towards the interior of the washing machine 1, of the upper part 3. The water distributor 4 conducts the water, which is supplied through a conduit 5, to the individual channels 15, 15.1, 15.2, which run through the interior of the upper part 3 and have, above the chambers 6.1, 6.2 individual openings 7, 16 that act as nozzles (figure 4). Through these nozzles 7, 16, the individual chambers 6.1 or 6.2 present in the box 3a are then filled with water, as shown in the sectional view of Figure 4 of the dispensing device 3. The treatment agent introduced into the respective chamber 6.1, 6.2 is ejected from the chamber 6.1, 6.2 with the water entering, dispensing to the tank (not shown) of the washing machine 1.
It is understood that the upper part 3 of the dispensing device 2, as shown in Figure 3, is fixedly arranged in the housing of the washing machine, and the box 3a, as shown in Figure 2, can be removed from the front side of the washing machine 1. The box 3a comprises two chambers 6.1 and 6.2 in this respect, the chamber 6.1 being designed for storing treatment agents, and in this case in particular powder detergent, for a main wash cycle. The treatment agent, as outlined in Figure 4, is ejected out of chamber 6.1 or 6.2 by means of the upper part 3 disposed above the box 3a by adding water to the washing process. In this regard, the upper part 3 comprises on its lower side nozzles 7, which are directed towards chambers 6.1 and 6.2. According to the invention it is now proposed that in one of the chambers 6.1, 6.2, and in this case in particular in the chamber 6.1, a separate container 8 is arranged to store a liquid additive, such as bleaching agent, which can be inserted into the chamber 6.1 forming a gap 9 between the wall 10 of the container and the wall 11 of the chamber, the nozzles 7 of the upper part 3 being directed towards the gap 9 to introduce the water into the detergent chamber 6.1.
In Fig. 4 it is further clarified that the water jets 12 caused by the nozzles 7 run down each side along the wall 11 of the chamber, so that a kind of wall can be formed on the wall 11 liquid film The two films of water running down the side walls 11.1 and 11.2 cause a kind of bath below the treatment agent stored in the lower zone 13 of the chamber, so that a caking or adhesion of the agent can not occur treatment, for example powder detergent, in the chamber 6.1. For this, the nozzles 7 are directed in particular inclined towards the wall 11.1 and 11.2 of the chamber, being arranged in their position above the gap 9 in the upper part 3.
As can be recognized from Figure 2 by the nozzles 7 outlined as points, the nozzles 7 are arranged in the dispensing device 3 along the side wall 11.1, 11.2 of the chamber and the front wall 11.3, so which, as already mentioned, form this liquid film also on the front wall 11.3. It is now understood, in view of the representation of Figure 4, that through the upper channels 15, 15.1, 15.2 within the upper part 3 the water supply takes place, providing the selective introduction of water into the channels 15, 15.1,
15.2 by means of the water distributor 4, as shown in figure 3. To empty the container 8 inserted in the chamber 6.1, there are provided centrally between the nozzles 7, additional nozzles 16 for the detergent chamber 6.1. Also these nozzles 16 are arranged in this respect inclined in the upper part 3. To selectively dispense the water through these nozzles 16, a separate channel 15 is provided in the upper part 3 which, depending on the stage to be executed in the washing program, is released or blocked by the water distributor. water for water inlet 5. The nozzles 7 for dispensing the treatment agent from the chamber 6.1 are associated with the channel 15.1. The nozzles 7.1 for dispensing the treatment agent from chamber 6.2 are associated with channel 15.2.
Figure 5 shows in the sectional representation in particular the nozzles 16 which allow the addition of water to the container 8. In this sense, the container 8 has on the cover 17 an elongated opening 18 for the water supply. In the rear area of the container 8, an interlocking means 24 can be arranged as a means for fixing the container 8 inside the chamber 6.1, which can be interlocked in a corresponding interlocking opening or edge in the rear wall of the chamber 6.1. A detailed representation of the container 8 is shown in Figure 6.
The separate configured container 8, shown in FIG. 6, has a lid 19 pivotally arranged in the front area for loading liquid treatment agent which, when the box 3a is removed, can be opened to introduce the agent therein of liquid or viscous treatment, for example bleaching agent. As can be recognized from figure 6, although also from figure 2, they are formed on the outside in the container 8 separators 20 to save the gap 9. This makes it clear that the container 8 can be easily inserted into the chamber 6.1 conically shaped, the gap 9 being obtained by inserting the container 8 into the chamber 6.1 as a consequence of the spacers 20 and thus guaranteeing in any case the bathing of the space 13 below the container 8.
In an improvement, in particular of the spacers 20, the spacers 20 are configured in cross-section, as can be recognized for example in Figure 6, from the point of view of their shape, as a wing. It is now understood that, for example, the formation of the water film on the walls 11.1, 11.2, 11.3 of the chamber does not produce points that have not been bathed due to the spacers 20, since they do not form any non-pulverized point that could result in a caking or adhesion of detergents.
In a convenient refinement, the bottom 21 of the container 8, as can be recognized in particular from Figure 5, has a bulged shape in section, a siphon 22 forming on the end side of the bulge the rear wall of the container 8. The siphon 22 operates in a known manner, the siphon 22 consisting essentially of a drop tube 23, through which, upon raising the level of liquid in the container 8, the discharge of the liquid from the container 8 takes place. In this regard the liquid then rises through the tube 23, when for example water is added through the nozzles 16, until the horizon of the drop tube 23 is reached at the upper end, so that, due to the joint action, it takes place emptying through the suction effect.
The invention also relates to the container 8, as shown in Figures 6 and 7, which is designed for a dispensing device 2 for use in a washing machine 1 for storing treatment agents, such as bleaching agents. In this regard, the container 8 can be inserted into one of the chambers 6.1, 6.2 of a washing agent box 3a, in particular in the chamber 6.1 for storing the detergent, as a separate container 8 for storing the separate treatment agent, such as bleaching agent, forming in the chamber 6.1 an interstitium 9 for bathing below the lower space 13 of the chamber between the wall 10 of the container and the wall 11 of the chamber. The container 8 has in this sense a cover 17, in which an elongated opening 18 for the water supply is arranged. In the front area of the container 8 there is provided a lid 19 pivotally arranged to load the bleaching agent, which, when the box 2 is removed, can be easily opened. In a refinement, in particular of the container 8, to introduce the container 8 into the chamber 6.1 are formed on the outside in the container 8 separators 20 to save the gap 9 for the bath below. In this regard, the separators 20 are configured in cross-section, from the point of view of their shape, as a wing, and must in particular prevent the formation of uncovered points, so that the detergent can not be caked in space 13 bottom of the camera. The container 8 as such is configured in this respect, from the point of view of its bottom 21, in the form of an arc, the container 8 being limited by a siphon 22, which also forms the rear wall of the container 8.
