Definitions
- the invention relates to a method for carrying out a cleaning program in a dishwashing machine, in particular in a domestic dishwasher, with a washing container, in the lower region of which a collecting sieve covered by a sieve is arranged, wherein the collecting pot a circulating pump for a rinsing liquid circulation system and a Emptying device is connected, and wherein the method comprises a screen cleaning section, in which by reducing the circulation pump delivery rate increases the level of the washing liquid from lying below the flat screen level on a level above the flat screen and then by increasing the circulation pump capacity again is lowered to a level lying under the flat screen.
- Such a method is from the EP 1 649 797 A1 known.
- a shutdown of the circulation pump As a result, the level of rinsing liquid is increased to a level above the flat screen and the deposits on the sieve are welded on.
- the circulation pump is switched on again and thus the level of the rinsing liquid is lowered to a level below the flat screen.
- the circulation pump is switched off and the flushing liquid emptied.
- the switching off of the circulation pump before emptying the rinsing liquid causes a renewed Aufschissemmen the deposits from the discharge area and they can settle again on the flat screen.
- the invention thus presents the problem to disclose a method for carrying out a cleaning program of the type mentioned, in which an effective and residue-free cleaning of the flat screen is achieved.
- the delivery rate of the circulating pump is lowered after the beginning of the flushing liquid emptying.
- noises are prevented at the end of the emptying process. It is expedient if the reduction of the delivery occurs continuously.
- further sieve cleaning sections are carried out in the course of the water-conducting program section.
- the filter cleaning sections can be performed with different, adapted to the cleaning of different screen areas circulating pump speed profiles, so that shadow zones are avoided and a complete screen cleaning is achieved. This is possible in a simple manner by the use of a variable-speed, in particular speed-adjustable circulating pump.
- the sieve cleaning sections should usefully be carried out in the pre-rinse and / or cleaning program section, because the highest amount of dirt prevails in these program sections.
- the washing container 1 has the shape of an upside down truncated cone with a circular cutout in the lower area.
- This section of the collecting pot 2 is used, which is usually made of plastic.
- a first nozzle 5 is formed, via which the inflow of softened fresh water (not shown) takes place.
- a second nozzle is used to connect the intake 31 of a circulating pump 3, which conducts the rinsing liquid in a circulation system via lines to different spray arms.
- the dishes are irrigated via spray nozzles with the rinsing liquid, then collected in the collecting pot 2.
- the lower spray arm 7 and its supply line 8 are shown in FIG.
- a third neck is formed centrally in the bottom 21 of the collecting pot 2, it is connected to the intake 41 of a drain pump 4.
- a sieve combination is used, consisting of a surface sieve 9, a coarse sieve 10 and a microfilter 11.
- a possible structure of such a sieve combination is from the DE 42 36 931 C2 known.
- the flat screen 9 filters food particles and the like from the circulated liquid and thereby prevents on the one hand a blockade of the circulation pump 3, on the other hand, a re-applying the dishes is avoided with these impurities.
- a recess into which the coarse sieve 10 is inserted In the middle of the surface sieve 9 is a recess into which the coarse sieve 10 is inserted. It forms with the microfilter 11 a downcomer 12, which leads to the intake 41 of the drain pump 4. Due to the arrangement of these two filters 10 and 11, the deposits located on the surface sieve 9, insofar as they do not adhere there, are rinsed into the downcomer 12 and held there during the rinsing liquid circulation. When you turn the drain pump 4, they are then sucked and transported into the sewer. Foreign bodies such. B. large food debris and fruit cores that could jeopardize the functioning of the drain pump are retained by the coarse screen 10.
- the amount of incoming water is so dimensioned in a water-conducting program section that, without operation of the circulation pump 3, a rinsing liquid level L o sets, which lies above the flat sieve 9.
- a rinsing liquid level L o sets, which lies above the flat sieve 9.
- a part of the washing liquid is transported in the rinsing liquid circuit, another part is located on the dishes.
- the sum of these two parts depends on the capacity of the pump 3, this in turn of the speed.
- a rinsing liquid level L u is reached during the circulation, which is below the flat wire. Compliance with the two levels can be ensured by level sensing or sensing the amount of water flow, taking into account empirical values for the amounts of water in the rinsing fluid circuit and for the wetting of dishes.
