Definitions

  • the invention relates to a household washing machine with lines for the distributed switched supply of fresh water, for the discharge of used Alkali and for the guidance of pressure equalization air.
  • Such washing machines are known and used (DE 37 34 117 A1) and regularly use more or less flexible pipe or pipe for the said pipes Hose sections for the respective connection of nozzles at different Locations of water or air treatment facilities located in the washing machine.
  • flexible hose lines between the nozzles of electrically switched solenoid valves and the inlet port of a detergent dispenser as well as an equally flexible hose line from the pressure compensation connection an overflow bend on the drain line with a corresponding one
  • sockets on the detergent dispenser to compensate used by pressure differences.
  • individual risers mostly made of flexible hoses between a drain pump and one Plastic overflow bend and - if available - a downpipe from the drain socket of a detergent dispenser to the drain pump housing in the form of a flexible hose line.
  • the invention has for its object in a household washing machine described above the most cost-effective system for water supply within the washing machine. It should be ensured that the for the system required individual parts in terms of numbers and manufacturing technology Require expenses.
  • this object is achieved in that for leading the lines a common plastic cable body from their supply points to their discharge points is provided, the feed line mouths via elastic Sealing sleeves sealingly connected to the supply and discharge locations and mechanically are held.
  • the lines for the Fresh water supply on the input side directly through the outputs of solenoid valves connected.
  • the immediate one is also advantageous in this context output connection of the lines for the supply of fresh water with the inputs of a detergent dispenser. This usually allows two or three individual hose lines between the solenoid valves and the Detergent dispenser along with those needed for sealing Avoid hose clips.
  • the line body also contains a line for guidance of overflow water.
  • Overflow water can, for example, via the detergent dispenser and from there via a directional drain to a drip pan be guided in the level sensor switchgear for overflow protection are arranged.
  • a pressure compensation line is also particularly advantageous in the line body can be integrated to guide pressure equalization air, the input side with a Vent pipe of the detergent dispenser and on the outlet side with a Overflow bend is directly connected.
  • the greatest advantage is a further development of the invention, in which the line body a standpipe and a downpipe for the discharge of the used lye and one contains these two pipes connecting overflow bend. Is of particular advantage thereby that the overflow bend to a return tank lying in the course of the riser pipe connected to retain an amount of lye required for backwashing is.
  • the integration of lye laxatives into the line body offers compared to the manufacture, logistics and assembly of individual line parts and hoses with their connecting elements have the greatest advantage in the integral Design of the management body.
  • the line body can be designed in a simple manner by that it is molded from a plastic blow molded part.
  • At least one tab on the lead body for provisionally holding the lead body is molded on before installing the cable connections.
  • Such tabs can be used for provisional holding of the line body Edges or slits are hung in the housing parts of the washing machine.
  • the invention is based on an exemplary embodiment shown in the drawing explained below.
  • a solenoid valve block on the rear wall 2 3 with two outlets and a detergent dispenser 4 attached.
  • the detergent dispenser 4 has on its rear underside (not visible) two inlet connections for the supply of fresh water and one Overflow nozzle for the removal of from the tub, not shown via the detergent supply line (also not shown) and the detergent dispenser 4 overflowing water.
  • the detergent dispenser has 4 another vent that connects to the free atmosphere Has. This ventilation nozzle regularly serves to remove air from the free atmosphere into an overflow bend in the drainage system so that if the delivery is interrupted of the drain pump, the water column in the riser pipe of the drain removal system tears off and not about the suction cup principle the contents of the tub sucks.
  • a line body 5 is provided, on the riser pipe 6 a water line 7 (individual component) is connected by a drain pump, not shown lye to be pumped out.
  • the integration of line 7 in the Conductor body 5 would be technically possible, for reasons of handling However, assembly is not recommended because the drain pump is very far from the rear wall, namely as far as possible on the front wall of the washing machine should be. Therefore, the lead body 5 would be much too bulky and would for this reason, logistical handling and assembly difficulties prepare.
  • a hose line 9 is connected, which is not closer to one here shown point out of the machine housing 1 and therefore on a Part of their length is shown in dashed lines.
  • the return tank 10 is piping in the course of an overflow bend (Fig. 2) and is designed quite flat and in front of one rear housing edge 11 guided around this edge, on the one hand as much as possible To offer content, but on the other hand as little as possible from the swinging tub assembly to occupy the required vibration space.
  • tabs 12 and 13 are attached to the line body, which by assigned Slots can be inserted in the rear wall of the housing and the cable body 5 give a movable hold in the longitudinal direction of the lines.
  • the line body 5 shown in detail in FIG. 2 contains those already discussed Riser and downpipes 6 and 8 and those arranged in the course of the overflow bend 14 Return tank 10.
  • the liquor to be pumped out of the connecting pipe 7 fills up the nozzle 15 and the riser 6 the return tank 10 before they over the Overflow bend 14 and the downpipe 8 reaches the drain hose 9.
  • the pump pressure subsides in the riser 6
  • the line body 5 also contains fresh water supply lines 17 and 18, the inlet side sockets 19 and 20 via elastic sealing sleeves 21 and 22nd connected to outlet ports (not shown) of the solenoid valves 3, (Fig. 1) are. In the same way, the outlet ports 23 and 24 of the lines 17 and 18 via sealing sleeves 25 and 26 with the inlet port, not shown Detergent dispenser 4 connected. Between the feed lines 17 and 18, a line 27 for guiding overflow water is arranged in the line body 5. At its inlet port 28 is also a sealing sleeve 29 Not visible overflow connection in the detergent dispenser 4 connected.
  • the outlet-side connector 30 of the line 27 can either be free or via a Sealing sleeve 31 open into a water guiding device that discharges Overflow water in a floor pan 32 (Fig. 1) leads, where not shown safety switching devices if necessary, signal the presence of overflow water.
  • the invention is not restricted to the exemplary embodiment shown.
  • the cable routing to the particular circumstances in a washing machine adapt, which also affects the position and position of the connecting piece.
  • further lines can be provided in the line body, for example a fresh leakage water line according to DE 37 34 117 A1. Should the feeder of fresh water and detergent from the detergent dispenser 4 not be connected in the upper part of the tub, but over a longer one Open the line into any area below in the tub, then it is also recommended to integrate the water / detergent line into the Conductor body 5.
