Definitions

  • the invention relates to a washing machine with a tub arranged in a machine housing in which a drum is rotatably mounted, wherein the tub cooperates with a Umflutpumpe and with a drain pump with at least one filter insert for separating foreign bodies from the wash liquor, and wherein arranged in a filter housing Filter insert is accessible from the outside of the machine housing for cleaning purposes.
  • lint filters or heavy body traps are used. While buttons, curtains rolls, etc. are deposited with a heavy body trap, finer foreign bodies such as threads or lint can be retained with a lint filter.
  • the filter insert is in this case used in a filter housing, which is also provided with a lint filter in addition to a labyrinth-like flow channel in order to meet in this way, in particular, the retention of fine particles.
  • the use of the filter and the Umflutgeophuses is designed in each case labyrinth-shaped, so that foreign bodies are filtered out and do not block the pump.
  • the use of the Umflutgeophuses must be particularly streamlined in terms of lint and threads, since the entire amount of alkali is pumped several times during the wash phase.
  • washing machines such as in the EP 1 295 980 A1 described flooding systems are installed.
  • two pumps are used, namely a drain pump and a circulating pump.
  • circulating pumps which are self-sufficient positioned in the washing machine housing and circulating pumps, which are flanged to the filter housing.
  • These filter housings have only one access, for example a turn out insert. This has the consequence that the access to the drain pump or the access to the pump blade is given, however, the access to the circulating pump is not present.
  • this error can not be eliminated in the circulating pump.
  • the foreign body can not be removed. It is therefore considered disadvantageous that there is no accessibility to the pump head or to the pump blade. Blockage of the circulating pump by a foreign object or by a thread ball can not be eliminated by the customer. In this case, the customer service should be called.
  • the invention is thus based on the object to further develop a washing machine in which the circulating pump and the drain pump can be easily maintained.
  • the solution is that advantageously two parallel, connected filter housing with two rotatable filter cartridges and two pumps are held.
  • the filter housing of the two pumps is in one piece or in this case consists of a component.
  • This unit consists of the pumping unit and the circulating unit. In the middle of the junction, these systems are brought together or fluidically in operative connection. In the present case, they are welded together.
  • a detachable connection is also conceivable, such as a bayonet or a screw cap.
  • the circulating pump is positioned on the left and the drain pump on the right. With respect to the position to each other are both housing parallel as horizontal in the washing machine housing inclined backwards.
  • both systems are parallel or horizontal, wherein the systems can also be positioned at an angle of 0 ° to 90 ° to each other, so that the systems can also be arranged one above the other.
  • the pump blades are accessible from the front through a service door. Both systems can be cleaned separately and independently. Both systems are self-sufficient in terms of pumps and filter cartridges. Different filter inserts or different labyrinths can be used separately from each other.
  • the foreign body insensitivity of the structural design is designed so that the downstream dimensions of the circulating system are each designed with respect to the previous dimension by a factor in the range of 1.05 to 1.2 larger.
  • the entire structural design is thus designed so that when a foreign body is sucked in, the downstream components can always happen. The same can also be transmitted to the drainage system, which is also occupied by a widening factor.
  • both the circulating pump and the drainage pump each comprise a filter housing with a removable filter insert, wherein both filter housings are arranged in the machine housing such that the filter inserts are accessible from the outside for revision.
  • the filter housings are arranged parallel next to each other in the machine housing.
  • the filter housings are connected to each other here.
  • the filter housing as a unit, made here of a component.
  • the filter housings are connected centrally by means of a flow channel.
  • the filter housing are slightly inclined backwards approximately between 5 ° - 25 ° arranged in the machine housing. It is of particular advantage that between the filter housings a slight gradient of about 1 ° - 5 ° is provided, which in particular causes an automatic venting of the two mutually parallel housing.
  • filter cartridges with labyrinth-like flow channels are respectively arranged in the filter housings.
  • the single filter insert can be inserted into the filter housing by means of a screw cap. After removing the filter cartridges from the filter housings, the pump impellers of the circulating pump and the drain pump are freely accessible.
  • the flow path to the discharge nozzle is dimensioned such that the dimensions of the discharge nozzle are larger by a factor than the dimension of the intake. According to the flow path and the discharge nozzle in the diameter is also sized by a factor greater than the diameter of the connecting tube between the circulating pump and discharge nozzle. The factor is about 1.1 for widening the flow path.
  • FIG. 1 shows in perspective a washing machine 1 with a arranged in a housing 2 tub 3, in which a drum 4 is rotatably mounted.
  • the tub 3 acts in this case with a circulating pump 5 and with a drain pump 6 with at least one filter insert 7 for separating foreign bodies from the wash liquor together. It is, as in particular from the view of FIG. 1 can be seen, arranged in a filter housing 8 filter insert 7 accessible from the outside of the machine housing 2 forth for cleaning purposes. From the FIG.
  • drain pump 6 and circulating pump 5 each include a filter housing 8.1 and 8.2 with removable filter cartridges 7.1 and 7.2, wherein both filter housing 8.1 and 8.2 in the machine housing 2 in such a way arranged that the filter cartridges 7.1 and 7.2 from the outside for inspection purposes, such as the regular cleaning, are accessible ( Fig. 2 ).
  • a closure 2b which can be closed with a flap, is arranged for this purpose.
  • the circulating pump 5 or its filter housing 8.1 is connected via a discharge hose 9 and the interposition of the filter housing 8.2 of the drain pump 6 with the tub 3, wherein the wash liquor through a connecting hose 10, which forms the pressure line for the pump 5, again during the washing process is returned to the drum 4.
  • the other filter housing 8.2 of the drain pump 6 is connected to the outlet hose 9, wherein the drain hose 11 is connected to the so-called return valve 12 in which forms a water column to effect in this way the seal on the tub outlet 13.
  • the drain safety is also the removal of the wash.
  • the filter housing 8.1 and 8.2 are arranged parallel to each other lying in the machine housing 2.
  • the filter housing 8.1 and 8.2 are interconnected, as shown in particular in the FIG. 4 can be seen.
  • the nozzle 14 can be seen, for the outlet hose 9, which cooperates in direct connection with the drain seal of the tub outlet 13.
  • the filter housing 8.1 and 8.1 are hereby made as a unit of one component.
  • the filter housing 8.1 and 8.2 are connected centrally by means of a flow channel 15.
  • the arrangement of the filter housing 8.1 and 8.2 in the machine housing 2 is such that the filter housing 8.1 and 8.2 are arranged slightly inclined backwards, this is especially in the FIG. 2 to recognize where the inclination can be between 5 to 25 °. Also exists between the two filter housings 8.1 and 8.2 a slight slope of about 1 to 5 °, which in particular in the FIG. 3 is indicated.
  • the filter cartridges 7.1 and 7.2 are provided with labyrinth-like flow channels 16.1 and 16.2.
  • the individual filter element 7.1, 7.2 can be inserted into the filter housing 8.1, 8.2 by means of a screw cap.
  • the individual filter element 7.1, 7.2 take out, so that then the open situation, as in the FIG. 5 shown, results. There are then after removing the filter sets 7.1 and 7.2 to recognize the pump wheels 17.1 and 17.2, which are then easily accessible to make cleaning work here.
  • the circulating pump 5 is dimensioned with its filter housing 7.1 with respect to the flow path to the discharge nozzle 18 such that the dimensions of the pressure port 19 is greater by a factor than the dimension of the intake manifold 20.
  • the discharge nozzle 18 dimensioned in diameter also by a factor greater than the diameter of the connecting tube 10 between the circulating pump 5 and discharge nozzle 18.
  • the Drain in which case the inner diameter of the intake manifold 14 is formed smaller than the inner diameter of the pressure port 11 a, wherein the inner diameter of the drain hose 11 is in turn formed larger than the discharge nozzle 11 a.
  • the extent of the expansion with respect to the respective diameter is about 1.1 mm, or is in a range of 1.05 to 1.2 mm.
  • Umflutsystem the inner diameter of the intake manifold 20 is 10mm, the pressure port 19 11 mm, the hose 10 12mm and the nozzle or the output in the door seal 13 mm.
