- The invention relates to a device for pumping out lye having a return flow tank, the volume of which is measured such that with the lye pump off, a predefined quantity of lye can flow back through the lye pump below the washing drum under gravity and having a lower pumping-out connecting element and an upper pumping-out connecting element.
- DE 35 06 761 C2 and DE 100 58 413 A1 disclose a washing machine of this type with a device for pumping out lye, which comprises a lower pumping-out connecting element connected to the pressure side of the lye pump, an upper pumping-out connecting element which can be connected for instance to an outflow and an interposed return flow tank. The return flow tank is manufactured in two pieces in DE 35 06 761 C2 and in one piece in DE 100 58 413 A1. The pumping-out connecting element and the return flow tank are connected to one another using conventional means such as a pipe coupling etc. The volume of the device for pumping out lye is measured such that with the lye pump off, a predefined quantity of lye can flow out of the device for pumping out lye back through the lye pump below the washing drum under gravity. This can take place by means of a simple backflow of the lye, but also by the back-flowing lye introducing a valve ball of the drain hose into a sealing seat for instance.
- With the known devices for pumping out lye, it is disadvantageous that the manufacture and assembly are comparatively costly.

The volume of the device for pumping out lye is measured such that with the lye pump off, a predefined quantity of lye can flow back through the lye pump below the washing drum under gravity, if necessary with the use of a return flow valve. The lower pumping-out connecting element, the return flow tank and the upper pumping-out connecting element are designed in one piece or seamlessly in the form of at least one partially flexible tube, with the tube being routed at least partially through a tube holding device, i.e. molded and/or fixed. In a minimal design, the device for pumping out lye thus only has two parts, namely the tube and tube holding device. In general, the device for pumping out lye only needs to fulfill the functions of the known return flow tank and the pumping-out connecting element in respect of the lye backflow. It does not need to recreate the form of the known device for pumping out lye. The function of the return flow tank and the pumping-out connecting element(s) can thus also be combined in a tube section.
- The provision of the inventive device for pumping out lye firstly simplifies and reduces costs involved in the manufacture, secondly facilitates the assembly and thirdly increases reliability.
- In an advantageous embodiment of the device for pumping out lye, at least one intermediate part is integrated in the tube, particularly if the intermediate part takes the form of a smooth connection with a ventilation hole. The connection is expediently so short, that the flexibility of the tube in the region of the tube holding device and/or its assembly is not noticeably restricted. The device for pumping out lye can however also comprise several intermediate parts, e.g. a further connection having a ventilation facility, e.g. for attaching sensors such as pressure or fluid sensors.
- It is a particularly advantageous embodiment if the device for pumping out lye features a tube holding device, which has a sealing area comprising a preferably cylindrical and/or annular tube feedthrough in the horizontal cross-section which is inserted therein as well as a connection attached thereto, and if the smooth connection can be introduced into the tube feedthrough of the sealing area of the tube holding device in a sealed manner. The outer shape of the sealing area is not established.
- The smooth connection in the sealing area is favorably sealed by means of sealing elements such as O-rings, particularly if the connection is restricted on both sides by the O-rings.
- It is advantageous for effective ventilation if the ventilation hole can be positioned accurately in the region of the connection. This can be assisted for instance by means of guide elements, such as rails, grooves for example etc.
- The tube can advantageously be fixed in the sealing area.
- The inner volume of the tube can generally be designed in a simple manner such that the volume corresponding to the known device for pumping out lye is adjusted over the length or the internal diameter of the tube for instance.
- If is favorable if the tube is at least partially a corrugated tube, preferably made out of plastic, in particular polypropylene.
- It is advantageous for a safe assembly and improved operational reliability, inter alia also a primary clamp trap, if the internal diameter of the tube is dimensioned differently and/or variably, particularly if it has an enlarged diameter in the connection region to the washing machine.
- Advantageously, the tube holding device has a first straight subarea facing the device connection, said first straight subarea merging via a curved area into a second straight subarea which runs perpendicular to the first straight subarea. The sealing area is favorably integrated in the second straight subarea.
- In the case of a device mounted on the washing machine, it can be advantageous for volume enlargements if the tube can be positioned in a circular or arched manner in the connection region to the device and comprises a corresponding length.
- In the following exemplary embodiments, the device for pumping out lye is described schematically in more detail, in which;
-
FIG. 1 shows a schematic representation of a vertical section of a washing machine with a device for pumping out lye, -
FIG. 2 shows a perspective view of a tube holding device, -
FIG. 3 shows a further perspective view of the tube holding device, -
FIG. 4 shows a perspective view of a device for pumping out lye with the tube holding device fromFIGS. 2 and 3 and with a suitable tube and -
FIG. 5 shows a side view of a section from the tube according toFIG. 4 . - In a drum-
shaped lye container 2 surrounded by themachine housing 14 of the washing machine 4 shown inFIG. 1 according to the prior art, awashing drum 6 is mounted in a rotatable fashion about a horizontal axis. Water can be fed to thelye container 2 by way of aline 8, amagnetic valve 10 and adetergent feed facility 12. Themaximum water level 16 that can be reached in thelye container 2 is illustrated schematically using a dashed line. Adischarge line 20 is connected to thebase 18 of thelye container 2, said discharge line running past afluff filter 22 to the intake side of alye pump 24. Adrain hose lye pump 24, said drain pump consisting of a lower pumping-out connectingelement 25 and an upper pumping-out connectingelement 26, which are connected with one another by way of areturn flow tank 30, with the two pumping-out connecting elements being flexible and preferably being so-called corrugated tubes. The upper pumping-out connectingelement 26 can be connected to an outflow or can be attached to a water outflow reservoir 28. - The volume of the
return flow tank 30 is dimensioned such that after pumping out lye, if thelye pump 24 is stopped, the lye flowing back out of thedrain hose return flow tank 30 through thelye pump 24 comes to rest at a level which is somewhat higher than thebase area 18 of thelye container 2. This ensures that if detergent is subsequently added from thedetergent feed facility 12, this detergent does not disappear in thedischarge line 20 on thebase 18 of thelye container 2, but is instead fed by water from thewater line 8 which also has to be introduced into thewashing drum 6 again. -
FIG. 2 shows a slanted perspective of atube holding device 1. This has a first straight subarea 9 directed downwards in the direction of the YO axis, said subarea 9 merging via a curved region in a secondstraight subarea 11, which lies perpendicular to the first straight subarea in the direction of the ZO axis. A cylindrical and/orannular sealing area 13 in the horizontal cross-section is integrated into the secondstraight subarea 11, saidsealing area 13 having aconnection 3 attached to the side. Thetube holding device 1 is provided with through holes for improved installability, weight and cost savings and is open on the side outside thesealing area 13. Retainers and/orinstallation aids 15 are also integrated into thesealing area 13. -
FIG. 3 shows the same tube holder device 1 (FIG. 1 ) in another view, which emerges from the axis of coordinates. - In a view similar to that of
FIG. 3 ,FIG. 4 shows a device for pumping out lye 5 having atube holding device 1 and atube 17 guided therein. This device for pumping out lye 5 replaces said device known from the prior art and referred to inFIG. 1 with 25, 26, 30. Thelower opening 19 is provided to allow a connection to the pressure side of thelye pump 24 of a washing machine, theupper opening 21 is intended for a connection to the outlet, e.g. to an outflow 28 (FIG. 1 ). -
FIG. 5 shows a sketch of a section of thetube 17 associated with thesealing area 13. Thetube 18 essentially consists of corrugated tube segments made out of polypropylene (PP). A smooth, cylindrical or connection-like section is integrated into thetube 17 as aventilation facility 27. For improved perceptibility of the details of the tube design in thesealing area 13, this part of the tube is detached from the overall length of thetube 17 and is illustrated larger than the remaining parts of thetube 17. At an axial distance from aventilation hole 29, which, in the assembled state, is positioned below theconnection 3 of thetube holding device 1, sealing O-rings 23 are attached to the exterior of theventilation facility 27. Upon insertion of thetube 17 into thesealing area 13 of thetube holding device 1, the O-rings 23 axially seal the internalannular sealing area 13 on theventilation facility 27 and thus theconnections 3. Theventilation hole 29 is ideally positioned in front of theconnection 3, this being possible for instance by means of corresponding guides. Nevertheless, provided the annular area at the level of theventilation hole 29 is at a sufficient distance from the internal wall of thetube holding device 1, positioning of the ventilation hole 28 precisely opposite the input of theconnection 3 is not necessary. - In the sealing
area 13 of thetube holding device 1, thetube 17 is provided with theventilation facility 27 of thetube 17 which is sealed in the axial direction (see alsoFIG. 5 .) The seal (here O-rings 23) ensures that liquid lye or lye steam running out of thetube 17 through theventilation facility 27 can be drained throughconnection 3 and a ventilation tube (FIG. 4 ) disposed in a sealed manner thereupon, and does not escape into the environment at the open ends of the sealingarea 13. - In the sealing
area 13, thetube 17 is logically fixed to thetube holding device 1, e.g. by means of a pressure connection by way of the O-rings 23, or however by means of other methods such as adhesive, catch mechanisms, screws etc. - In the region of the
lower opening 19, it is advantageous for providing an adequate liquid volume and for the function as a collection container and/or primary clamp trap, if the internal diameter of thetube 17 is comparatively enlarged there. - During connection to a washing machine, the
tube 17 can expediently be so long that it is positioned in the area of the device connection in an arc, so that this arc creates additional volume. An enlargement of the internal diameter can simultaneously create more volume in this area. - The length of the
tube 17 can be adjusted as needed. - In general, the device for pumping out lye 5 can be adapted to the structural conditions, e.g. as a result of varying the shape, diameter, length, material etc.
