Description

The invention relates to a flushing device for liquid and / or powdery treatment agent for use in a washing machine, with at least one chamber for storing the treatment agent, and above the chamber arranged nozzles through which water is passed to the treatment agent.

Drawers for detergents are known from the prior art, which are equipped with a flushing device. Via the flushing device, fresh water is flushed through the chambers of the drawer so that the powdered or liquid detergent stored therein is entrained and mixed with the washed-in water in order to supply it to the washing process. For example, from the DE 101 50 878 A1 or the DE 75 13 925 U1 a distribution box for a washing machine with different guide channels known, over which the different detergents can be removed. Another embodiment of a drawer for laundry detergents is known from EP 0 685 587 A1 known, in which a verable tank for storing a liquid bleaching agent is arranged in one of the chambers. Next is from the prior art according to the DE 195 05 292 A1 a drawer for a detergent dispenser known, which also has a plurality of chambers, one of the chambers for the storage of the liquid detergent is determined and cooperates with a so-called siphon device with which the liquid detergent can be removed easily and safely. From the DE 34 04 247 A1 a detergent dispenser is known in which the partition wall between two adjacent chambers has an additional solid molded liquid detergent compartment.

The invention has for its object to provide a detergent dispensing device for use in a washing machine, which allows in a simple way, the loading and flushing of additional treatment agents.

According to the invention the object is achieved with the features of the independent claims 1 or 12. Advantageous embodiments and developments of the invention will become apparent from the dependent claims 2 to 11 and 13 to 18.

The advantage achievable with the invention is that at the same time at least two different treatment agents can be stored in a chamber for storing a first liquid or pulverulent treatment agent, for example detergent. For this purpose, an additional, separate is in the chamber for storing the detergent Container for storing a further liquid treatment agent, for example bleach used. For flushing the treatment agent nozzles are arranged above the chamber through which water is passed into the chamber or in the container to the respective treatment agent. For the flushing of the treatment agent from the chamber, a first subset of nozzles is provided, which are arranged in lateral sections above the chamber. For the flushing of the treatment agent from the separate container, a second subset of nozzles is provided, which are arranged in a central portion above the chamber or the container used. The introduction of the water via the first and second subset of nozzles is selectively controllable, so that the flushing of the respective treatment agent takes place in dependence on the step within a washing program or treatment program.

For reliable flushing, the container can be inserted into the chamber so that a gap between the chamber wall is formed in the chamber. The subset of nozzles for the flushing of the treatment agent from the chamber are directed into the gap. Through the lateral gap between the container and the walls of the chamber, the nozzles of the first subset flush the water to the side walls and thus laterally under the detergent. This results in a clean rinse, which takes place without clumping of the detergent.

In an advantageous embodiment, the nozzles are arranged directed above the gap space inclined to the chamber wall. The nozzles thus spray the water on the chamber wall, so that it runs like a film on the chamber wall and thus causes in the lower region of the chamber, a rinsing of the treatment agent, for example, powdered detergent. The formation of the water film inhibits caking on the chamber wall, as water continues to run over the first subset of nozzles until the chamber is emptied. The first subset of nozzles is arranged in the flushing device such that they are aligned along the chamber wall.

For emptying the container, it is expedient that the second subset of nozzles is arranged substantially centrally above the container. The container as such in this case has a lid which includes an elongated opening through which water can also be injected via the flushing device for emptying. The second subset of nozzles is located above this opening to provide a reliable flushing of the water into the container.

In an advantageous development for the loading of the container in the front region of the container, a pivotally arranged flap is provided.

In an expedient embodiment, spacers for bridging the gap space are arranged on the outside of the container, wherein a space is kept free below the container, through which the treatment agent is flushed out of the chamber. This gives the container in the chamber a certain stable position, providing a substantially shadow-free rinsing and reliable flushing of the treating agent from the chamber.

In an advantageous development, the spacers are formed wing-like in cross-section of their shape. This shape influences the passing water in such a way that mud shadow on the spacers are avoided or at least reduced, whereby clumping and residual formation of powdered treatment agents on the chamber walls or container walls are avoided.

In a further embodiment, the container has a device for almost complete emptying. For this purpose, the bottom of the container has an inclined or curved shape, which terminates at the end with a siphon as the rear wall of the container. Thus, if fresh water is applied to the container via the flushing device, a level is established with respect to the suction lever device which allows the fluid to penetrate into the so-called drop tube for emptying, so that the container automatically deflates.

In an expedient embodiment, the container has on its outer wall means for fixing its position within the chamber. It is expedient to arrange a locking means on the rear wall, which engages in the intended position in an opening of the rear chamber wall, whereby the position of the container in the longitudinal direction in the chamber reliably taken and held.

The invention likewise relates to a container for a flushing device of a washing machine for storing liquid treatment agent, wherein the container can be inserted into a chamber of a flushing device. The chamber is designed for storing liquid or pulverulent treatment agents, such as washing powder. The container storage of another liquid treatment agent, such as bleach, is separately used to form a gap between the container and chamber wall in the chamber.

In an expedient embodiment, the container has a lid with an elongated opening for the water supply, wherein in the front region of the container for the loading pivotally arranged flap is provided.

So that in particular a shadow-free rinsing of the container according to the invention can take place, are on the outside of the container spacers for bridging the gap arranged, wherein the spacers are formed wing-like in cross section of their shape. This training ensures on the one hand, that the container can be used in a Stabillage in the chamber, without here the flushing with fresh water impairs the container in any way, as a result of the shape of the spacer is given a low-shadow possible flushing.

In a further development, the bottom of the container has a curvature on average, which forms the rear wall of the container with a siphon end. Due to this design, a drainage mechanism is provided in particular in the container, which is fed via the flushing device, so that an automatic emptying of the container takes place.

1 shows a perspective view of a detail of a washing machine 1, wherein in the front of the washing machine 1, an extendable drawer 3a is arranged. The drawer 3a includes one or more chambers for storing treatment agents, wherein within the washing machine 1, a flushing device 2 is arranged for flushing the treatment agent from the chambers. The drawer 3a of the flushing device 2 is shown in more detail in the individual view in FIG. FIG. 3 shows the flushing device 2 in perspective, a flat upper part 3 being arranged above the drawer 3a. For selective steering of the water supply within the upper part 3, a controllable water separator 4 is provided, which is preferably arranged on the rear, to the interior of the washing machine 1 side facing the upper part 3. The water diverter 4 directs the water, which is supplied via a line 5, in the individual Channels 15, 15.1, 15.2, which run within the upper part 3 and above the individual chambers 6.1, 6.2 as openings acting nozzles 7, 16 (Fig. 4). By means of these nozzles 7, 16, in turn, the individual chambers 6.1 or 6.2 present in the drawer 3a, as represented in the sectional view of FIG. 4 of the flushing device 3, are filled with water. The treatment agent filled in the respective chamber 6.1, 6.2 is flushed out of the chamber 6.1, 6.2 into the tub (not shown) of the washing machine 1 with the incoming water.

It goes without saying that the upper part 3 of the flushing device 2, as shown in Figure 3, is fixedly arranged in the washing machine housing, wherein the drawer 3a, as it appears in Figure 2, from the front of the washing machine 1 pull out. The drawer 3a comprises two chambers 6.1 and 6.2, wherein the chamber 6.1 for storing treatment agent, and in particular of powdered detergent, is intended for a main wash. The treatment agent is, as sketched in FIG. 4, rinsed out of the chamber 6.1 or 6.2 by means of the upper part 3 arranged above the drawer 3a through the addition of water for the washing process. In this case, the upper part 3 comprises on its underside nozzles 7, which are aligned with the 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 here in particular in the chamber 6.1, a separate container 8 for storing a liquid adding agent, such as bleach, is arranged, which forms a gap space 9 between container wall 10 and chamber wall 11 is inserted into the chamber 6.1, wherein the nozzles 7 of the upper part 3 are directed into the gap 9 for introducing 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 each run down along the chamber wall 11, so that a kind of liquid film can form on the chamber wall 11. The two water films running down on the side walls 11.1 and 11.2 cause a kind of under-flushing of the stored treatment agent in the lower chamber area 13, so that a clumping or caking of the treatment agent, for example detergent powder, in the chamber 6.1 can not take place. For this purpose, in particular the nozzles 7 are directed at an inclination to the chamber wall 11.1 and 11.2, wherein they are arranged in their position above the gap space 9 in the upper part 3.

As can be seen from FIG. 2 with reference to the nozzles 7 sketched as dots, the nozzles 7 are arranged in the flushing device 3 along the lateral chamber wall 11.1, 11.2, and the end wall 11.3, so that, as already mentioned, this liquid film also form on the front wall 11.3. It goes without saying, 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, wherein the selective introduction of water into the upper channels 15, 15.1, 15.2 through the water diverter 4, as shown in Figure 3, is provided. To empty the container used in the chamber 6.1 8 more nozzles 16 are provided centrally between the nozzles 7 for the detergent chamber 6.1. These nozzles 16 are arranged at an inclination in the upper part 3. For selective flushing of the water through these nozzles 16, a separate channel 15 is provided in the upper part 3, which is enabled or disabled depending on the step to be processed in the wash program through the water gate for the water inlet 5. The nozzles 7 for the flushing of the treatment agent from the chamber 6.1 are assigned to the channel 15.1. The nozzles 7.1 for the flushing of the treatment agent from the chamber 6.2 are assigned to the channel 15.2.

FIG. 5 shows, in the sectional view, in particular the nozzles 16 which allow the addition of water to the container 8. In this case, the container 8 in the lid 17 an elongated opening 18 for the supply of water. In the rear region of the container 8, a latching means 24 is arranged as a means for fixing the container 8 within the chamber 6.1, which can be latched into a corresponding latching edge or opening in the rear wall of the chamber 6.1. An individual representation of the container 8 is shown in FIG.

The separately formed receptacle 8 shown in Fig. 6 has a hinged flap 19 in the forward area for liquid processing agent loading which, when the drawer 3a is pulled out, can be opened to contain the liquid or viscous treating agent therein Bleach to fill. As can be seen from FIG. 6 but also from FIG. 2, spacers 20 are formed on the outside of the container 8 for bridging the gap 9. Thus, it is clear that the container 8 can be easily inserted into the conically shaped chamber 6.1, wherein when using the container 8 in the chamber 6.1 as a result of the spacer 20, the gap 9 results and thus the under-flushing of the space 13 below the container 8 guaranteed in any case.

In a further development, in particular the spacer 20, the spacers 20 in cross-section, as can be seen for example in Figure 6, formed from their shape wing-like. It now goes without saying that now, for example, the water film forms on the chamber walls 11.1, 11.2, 11.3, it can come to any rinse shadows due to the spacer 20, because they form their flow orientation forth no spray shadow that a clumping or caking of Detergents would result.

In an expedient development, the bottom 21 of the container 8, as can be seen in particular from Figure 5, in section a curved shape, wherein the end of the curvature of a siphon 22 forms the rear wall of the container 8. The siphon 22 operates in a known manner, wherein the siphon 22 consists essentially of a drop tube 23, takes place through the increase of the liquid level in the container 8, the removal of the liquid from the container 8. In this case, the liquid then rises in the tube 23, if, 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 then the emptying takes place due to the suction effect.

The invention also relates to the container 8, as shown in Figures 6 and 7, which is intended for a flushing device 2 for use in a washing machine 1 for storing treatment agents, such as bleaching agents. The container 8 is in one of the chambers 6.1, 6.2 of a detergent drawer 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 bleach, forming a gap 9 for flushing the lower chamber space thirteenth be used between container wall 10 and chamber wall 11 in the chamber 6.1. The container 8 in this case has a lid 17, in which an elongated opening 18 is arranged for the water supply. In the front region of the container 8, a flap 19 is arranged for the loading of the bleach, which, when the drawer 2 is pulled out, is easy to open. In a further development, in particular of the container 8 for the introduction of the container 8 in the chamber 6.1, 8 spacers 20 are formed on the outside of the container for bridging the gap 9 for the scouring. In this case, the spacers 20 are formed wing-like in cross-section of their shape, which should in particular prevent that form rinse shadows, so that it can come to no clumping of the detergent in the lower chamber space 13. The container 8 as such is arcuately formed from its bottom 21 ago, wherein the container 8 is bounded by a siphon 22, which also forms the rear wall of the container 8.
