Definitions

  • Household appliance in particular dishwasher with a water softener.
  • the invention relates to a household appliance, in particular a dishwasher, with functional devices for controlling the work processes, for circulating and pumping out liquid, and a device for softening water with a salt vessel for treating regeneration brine.
  • the salt vessels for softening devices in dishwashers and the like are arranged in the known systems in such a way that the water overflowing when the salt is refilled and, if appropriate, also the spilled salt can run off into the sump of the machine.
  • the filler neck of the salt vessels in the interior of the rinsing container are usually fastened in a liquid-tight manner in the bottom of the rinsing container.
  • This arrangement has the disadvantage that the filler neck is difficult to access because the operator has to reach over the opened dishwasher door and at least remove the lower crockery basket.
  • This known arrangement also has the disadvantage that if stainless steel inner containers are used, corrosion can occur if the salt container is not rinsed immediately after filling and the brine is thus removed from the container.
  • the invention is based on the object of avoiding the disadvantages described above by means of a suitable design and nevertheless ensuring full functional reliability.
  • this object is achieved in that at least the salt vessel of the functional devices is arranged in the machine base via flexible lines in such a way that it can be moved operationally to the loading side in front of the machine front.
  • both service and operational maintenance work can be significantly simplified and thus improved without additional effort if, together with the salt vessel, other components, in particular e.g. the wastewater pump, but also valves and possibly control elements can be moved out to the front because they are easily accessible in this position.
  • other components in particular e.g. the wastewater pump, but also valves and possibly control elements can be moved out to the front because they are easily accessible in this position.
  • an overflow container to the salt container, e.g. to be assembled in one piece with the salt vessel.
  • the overflow vessel can be connected to the waste water pump by switching on a float valve or the like in such a way that it is pumped empty each time there is a pumping process.
  • the salt vessel and the overflow container are also advantageous to provide with a suitable pouring rim that catches spilled salt so that it then e.g. can be wiped into the overflow tank.
  • an overflow vessel can be avoided according to a development of the invention in that the salt vessel via a lockable overflow line with a Drain shaft or the inlet of a sewage pump of the device is connected.
  • This overflow pipe must be designed so that it is in the B e-operating state of the device shut off, so that the brine is forced into the Enthärtergefäß and not in the overflow during the regeneration process. To avoid unnecessary salt loss, it is advisable to arrange the mouth of the overflow pipe in the salt vessel above the fill level. This also has the advantage that the overflow line can be closed by a stopper which is held in the liquid-tight, but movable, wall of the salt vessel.
  • Figure 1 shows a schematic representation of a dishwasher with a salt vessel arranged in the machine base.
  • Figures 2 and 3 show in side and plan view a salt vessel with an attached overflow tank.
  • Figures 4 and 5 show in side and plan view a dishwasher with a plurality of functional elements arranged in the base and a salt vessel.
  • FIG. 6 shows a salt vessel according to FIGS. 4, 5 in detail in section.
  • FIG. 1 shows a dishwasher with the machine body 1, the loading door 2, a cover plate 3 and a base panel 4 in a side view.
  • the base cover 4 is connected to the machine body 1 via a guide 5 connected in such a way that it can be moved out operationally.
  • a salt vessel 6 is held on the base panel 4 or the guide 5 and is connected to the functional devices of the dishwasher via flexible lines 7.
  • FIGS. 2 and 3 show in side and plan view, partly in section, a salt vessel 10 used for processing the regeneration brine with an inlet nozzle 11 and an outlet nozzle 12.
  • the salt vessel 6 has a filler neck 13 which is provided with a closure cap 14.
  • the closure cap 14 has a cylindrical collar 15 which bears against a conical surface 16 of the filler neck 13 with the interposition of an annular seal 17.
  • openings 18 are formed in the filler neck, which allow the salt water to pass from the salt vessel 10 into the collecting container 19.
  • the collecting container 19 is closed with a lid 20.
  • the opening 21 serves on the one hand for ventilation of the vessel and on the other hand forms a passage for spilled salt.
  • both the salt vessel 10 and the overflow vessel 19 connected to it are provided with a pouring rim 22.
  • the overflow vessel 19 has on the bottom a connection 23 which, provided with a float valve 24, establishes the connection to a sewage pump, not shown.
  • the cap 14 is removed and salt is poured into the vessel 10, the displaced water runs through the openings 18 In the overflow vessel 19. Spilled salt can be wiped from the area given by the pouring rim 22 through the opening 21 into the overflow vessel 19. The overflowing salt water runs through connection 23 to the sewage pump and into the sump of the machine.
  • the closure lid 14 can be held in the closed position via a screw thread or via a bayonet closure.
  • connection 23 If water is let into the dishwasher for operation, the line to connection 23 is also filled.
  • the float valve 24 floats and remains closed until the corresponding line is emptied again by the waste water pump.
  • FIGS. 4 and 5 show a side view and a top view of the lower part of a dishwasher with the side wall 31 and the feet 32.
  • functional elements of the dishwasher are arranged on rails 33 which are extendable and connected to the base panel 34.
  • a multi-way valve 35 and a waste water pump 36 are given as an example.
  • a salt vessel 37 is arranged, the open lid 38 of which carries the closure 39 for the salt filling opening and an actuating plunger 40.
  • a Sight glass 51 covers the salt concentration indicator.
  • the salt vessel 37 is connected via flexible lines 61, 62 to a water supply softening vessel and a sewage pump.
  • FIG. 6 shows in section details of a salt vessel 37 with the container 42, in which a sieve insert 43 is inserted on the bottom side.
  • the salt vessel 37 in the wall 57 has a holder 44 for a float indicator, a pipe socket 45, which is closed off by a membrane 46, an intermediate floor 47 and a collar-like part 48, which forms the fill opening 49.
  • the vessel is rectangular and has a hinge 50 on one longitudinal edge, with the aid of which the lid 38 can be brought into the closed position.
  • FIG. 6 shows the cover 38 in the closed position, the right half in the open position.
  • An actuating plunger 40 and a sight glass 51 are attached or formed on the cover 38 in addition to the sealing plug 39.
  • the cover 38 is held in the closed position by a catch 52 arranged on the front.
  • a bellows 53 is placed around the collar 48, which facilitates the filling of the salt through the opening 49 as a funnel. The bellows 53 is pressed into the folded position shown in the left half of FIG. 6 when the cover 38 is closed.
  • the actuating plunger 40 is arranged in such a way that when the cover 38 is closed it presses on the membrane 46 in such a way that the sealing plug 54 fastened to the membrane closes the overflow line 55.
  • the transparent cap 41 of the holder 44 is inserted tightly into the wall 57.
  • the salt container 37 is moved out of the base of the machine 1, 31 and brought into the position shown in FIGS. 4 and 5.
  • other suitable holders can also be used, in particular those in which the salt vessel 37 executes not only a horizontal but also a vertical movement in front of the machine 31 in order to increase the gradient from the salt vessel 37 to the downcomer.
  • the filling opening 49 and the overflow 55 are free and the bellows 53 in the funnel-shaped position, so that salt can be easily filled.
  • the water volume displaced by the filling of the salt runs through the released overflow pipe 55 and the flexible line 61 connected to the nozzle 60 into the drainage shaft, from which it can then be drained or pumped out.
  • This described embodiment has the additional advantage that the extendable base can be brought into the operating position only when the lid 38 is closed, that is to say only when the salt vessel 37 is closed and when the overflow line 55 is closed.
  • an electrical lock can ensure that the machine can only be started when the base is retracted.
  • the overflow line 55 is expediently connected directly to the waste water pump 36 via the connecting piece 60.
  • Line savings also result e.g. through the direct connection of one of the water valves 35 to the salt vessel 37.
  • several functional units can also be combined to form an assembly unit and stored in the pull-out device base. Molded plastic parts can also form common housings for different functional units.
