Definitions

  • the invention relates to a program-controlled dishwasher, in particular a commercial cleaning or disinfecting machine with a washing container and a safety overflow connected to the washing container, wherein the safety overflow disposed in a Spül instructerwand opening with an overflow edge and a water reservoir forming overflow chamber with a lying over the overflow edge Has outlet.
  • the flushing chamber is liquid-conducting connected to a safety overflow. This has an overflow edge to the washing room and an opening into the sewage network or in a drip tray drain, wherein the overflow edge is disposed above the present during flushing in the washing compartment liquid level.
  • An above-described dishwasher is from the DE 103 17 787 B3 known.
  • the first chamber overflow chamber opens into a second chamber, which in turn is equipped with a drain pipe.
  • the opening into the second chamber outlet of the overflow chamber is arranged above the overflow edge of an opening between the washing and overflow chamber, so that forms a siphon-like closure of the opening when the overflow chamber is filled.
  • moisture and odors are prevented from escaping from the washing, on the other hand, the washing can be sealed during the execution of a drying program.
  • Due to the known design of the overflow chamber a collecting volume is formed in which contaminated rinsing liquid is carried off into the later program sections and even into the subsequent rinses. In particular, in commercial cleaning and disinfection machines the retention of rinsing liquid in the overflow chamber must be prevented.
  • the invention thus raises the problem of avoiding the carryover of alkali in the region of the overflow chamber in a dishwasher of the type mentioned.
  • the means comprise a drain with a valve switchable by the program control.
  • the means comprise a suction line opening into the overflow chamber. This eliminates the need for valves, which can clog because of their small opening cross-section and also resist chemical and thermal stresses either not or only with great expense. It is particularly advantageous if the suction line opens into the drain area of the washing container in front of a drain pump or a drain valve. This allows the overflow chamber in a simple manner, d. H. be exhausted by using the suction lever effect with already existing means simultaneously with the washing container.
  • the fresh water inlet opens into the overflow chamber to the washing.
  • this makes it possible to fill the overflow chamber in a program-controlled manner, thus achieving, for example, the necessary sealing of the rinsing tank for the drying process.
  • this protects in a very simple manner the water inlet area from splashes of spray in the washing. Such protection is required if water is sucked back into the supply network via the fresh water inlet.
  • FIG. 1 shows a safety overflow 1 for a known per se and therefore not shown in their complete training program-controlled dishwasher 2.
  • This has a washing container 3, which is closed on the front page 4 by a door, not shown.
  • the rinse tank 3 is fluidly connected to the safety overflow 1 mounted on a housing outer wall 5 of the dishwasher 2, shown in detail in FIG.
  • an opening 6 is provided in the washing container 3, to which the housing side a container 7 connects.
  • the lower edge of the opening 6 defines an overflow edge 8, through which the water from the washing container 3 to the container 7 and vice versa can flow.
  • a downwardly open angle plate 9 generates a siphon-like, symbolized by the arrow 10 deflection, which closes the rinsing tank 3 airtight to the outside environment 11 in the filled state.
  • a partition wall 12 divides the container 7 in an overflow chamber 13 with the deflection and a drain chamber 14 with a drain pipe 15.
  • the upper edge of the partition wall 12 defines the outlet 16 of the overflow chamber and is higher than the overflow edge 8.
  • In the overflow chamber 13 opens via an opening 17 in the angle plate 9 of the water inlet 18, wherein optionally or in combination tap water, softened water or demineralized water can be used.
  • the washing container 3 is formed in the lower region to form a collecting trough 20, which opens into a collecting pot 21. From there, the rinsing fluid passes through a first branch 22 into the intake 23 of a drain pump 24 and a second branch 25 in the intake manifold 26 of a circulation pump 27.
  • the drain pump 24 conveys the liquid through its discharge nozzle 28 in a sewer, not shown, the circulation pump 27th distributes the liquid via a first discharge port 29 to spray, which are arranged in a known manner in the washing container 3.
  • Figure 1 shows only the supply line 30 to the spraying devices not shown, which may be formed, for example, as spray arms or injector nozzles.
  • a second pressure port 31 of the circulation pump 27 is guided to a bypass line 32, which in turn opens into a suction line 33.
  • the suction line dives with its one end 34 in the overflow chamber 13 into the bottom region and is guided with the other end 35 to a branched junction 36 on the intake 23 of the drain pump 24.
  • the collection pot 21 directed edge of the junction 36 is provided with a storage edge 37.
  • the circulation pump 27 is switched off and then the liquid is emptied from the washing container 3.
  • the drain pump 24 is turned on and conveyed the liquid in the sewer.
  • the overflow chamber 13 is then the reaching to the overflow edge water mask stand.
  • a negative pressure in the suction line 33 is generated by the storage edge 37.
  • the liquid which is the water mask in the one end 34 of the suction pipe 33, raised above the highest point 38.
  • the entire contents of the overflow chamber 13 emptied by the siphon principle in the intake 23 of the drain pump 24 and is transported into the sewer.
  • the above-described program sequence takes place during all water-bearing program sections.
