According to the invention this object is achieved by a siphon with the features of the main claim. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

The invention offers the advantage that capillary effects in the area of the siphon can be avoided by separating the mold above a storage level of the dispenser or in the area of a transitional arch of the siphon. Advantageously, such a siphon also requires less space compared to a design with inner tube and siphon cap.

It is presented a siphon for a Einspülkasten a washing machine, the siphon having the following features:
a first suction-cup part and a second suction-cup part, wherein the first suction-cup part and the second suction-cup part are connected or connectable to a tube having a suction port, an outlet port, and a transitional arc disposed between the suction port and the outlet port, a division plane between the first suction-port part and the first suction-cup part second Saugheberteil in the operating state of the siphon extends at least partially above a maximum level of the Einspülkastens representing level level and / or intersects the transition arc.

Under a siphon can be understood a tube-like device for sucking a textile treatment agent or water from the Einspülkasten. Under a Einspülkasten, for example, a Wassereinspülkasten be understood with a pre-wash, main wash or softener compartment. Under a washing machine can alternatively be understood a washer-dryer. Under a first or second Saugheberteil may be a tubular or semi-tubular, straight or curved portion of the Suction lifter be understood. A division level can be understood as a level of a shape division. A filling level can be understood as meaning a storage level of the Einspülkastens. For example, the siphon may be a one- or two-part injection molded part. Under a transition arc, a suction pipe and the outlet opening interconnecting curved pipe section of the siphon can be understood. For example, the suction opening or, additionally or alternatively, the outlet opening in the operating state of the siphon may be facing a bottom of the Einspülkastens.

According to one embodiment, the dividing plane in the operating state of the siphon can extend horizontally at least in sections. As a result, capillary effects in the division plane can be avoided particularly effectively.

According to a further embodiment, the tube may have an intake pipe with the intake opening and an outlet pipe with the outlet opening. In this case, the transitional bend connecting the intake manifold and the outlet pipe to a U-shaped tube. The intake pipe or the outlet pipe may, for example, be a pipe that runs for the most part in a straight line. This can ensure that there is no connection between an intake side and an outlet side of the siphon, which extends into the storage level.

Advantageously, the first Saugheberteil the intake pipe or, additionally or alternatively, form the outlet pipe.

It is also advantageous if the first suction-cup part forms a first part-section of the transitional arc and the second suction-cup part forms a second part-section of the transitional arc. This allows easy demolding of the siphon.

According to a further embodiment, the first suction-cup part and the second suction-cup part can be pushed into one another or pushed into one another. As a result, a positive connection between the two Saugheberteilen be created. Thus, the stability of the siphon can be increased.

Depending on the embodiment, the first Saugheberteil and the second Saugheberteil can be connected or connectable by form or material connection or by form and material connection. This allows the siphon to be made very stable.

FIG. 4 shows a schematic representation of a siphon 400 according to an embodiment. The siphon 400 for a dispenser box of a washing machine comprises a first suction-cup part 402 and a second suction-cup part 404, which can be combined with one another by way of example here as a U-shaped tube. According to this embodiment, the first Saugheberteil 402 forms a lower part of the siphon 400. The lower part comprises an intake tube 406 with a suction port 408 and an outlet pipe 410 with an outlet opening 412. Exemplarily, the two tubes 406, 410 largely formed in a straight line and a likewise the Lower part associated first portion 414 of a transition arc 416 of the U-shaped tube, here a lower half of the transition arc 416, U-shaped interconnected. Similarly, the second Saugheberteil 404 forms a second portion 418 of the transition arc 416, here corresponding to an upper half of the transition arc 416th

According to one embodiment, the two suction lever parts 402, 404 are slidable into one another and thus can be connected to one another in a form-fitting manner. This is in FIG. 4 through a big vertical arrow indicated. Depending on the exemplary embodiment, the two suction lever parts 402, 404 can additionally or alternatively be connected to one another by material engagement, for example by welding or gluing.

A division plane 420 between the two suction-lift parts 402, 404, schematically indicated here by a dashed-dotted line, is selected, for example, such that it runs above a level 422 in the operating state of the siphon 400, the level representing a maximum level or a storage level of the Einspülkastens. The level 422 is indicated schematically by a further dashed line. It is particularly advantageous if the dividing plane 420, as in FIG FIG. 4 to see at least partially horizontally.

Depending on the type of washing machine, the siphoning principle of a softener compartment can not always be due to the space used, as is the case in FIG. 1 is shown to be applied. Alternatively, a siphon in the form of an upside down U can be realized, which is divided in the longitudinal direction in two parts to demold the component can, as shown in the Figures 2 and 3 is shown. The two parts are welded together in the longitudinal direction. However, this can lead to different capillary effects outside of the siphon, which should be avoided if possible.

For this reason, the approach presented here, the siphon 400, in particular in the form of an upside-down U, which is not divided in the longitudinal direction, but is separated horizontally, the component separation is above the storage level. As a result, in contrast to a siphon with inner tube and siphon cap, which requires a spout down, space can be saved. Due to the horizontal separation, capillary effects on the component partitions can be avoided. Furthermore, will an up to the storage level reaching connection between intake and outlet side avoided.

It is particularly advantageous if the siphon 400 has a horizontal separation in the region of the transitional bend 416. The separation is outside the storage level. The siphon 400 consists in particular of a lower part 402 and an upper part 404, wherein the intake tube 406, the outlet tube 410 and the lower half 414 of the transitional bend 416 are located in the lower part 402. In the upper part 404, however, is the upper half 418 of the transition sheet 416. According to one embodiment, the upper half 418 of the transition sheet 416 immersed in mounting the siphon 400 in the lower part 402 and thereby forms a completely U-shaped siphon, as in FIG. 5 shown. Both components 402, 404 are easy to demould, since only one Entformrichtung is necessary. Thus, there are no more unwanted capillary effects. The media is then rinsed in when needed.
