Definitions

  • the invention relates to a washing method for dishwashers with at least two spray devices and dishwashers with at least two spray devices in which the washing method is intended for use.
  • Dishwashers with alternating operation of the spray levels have long been known, for example from DE 24 28 901.
  • the spraying devices are simultaneously fed with the liquid conveyed by a circulating pump.
  • This so-called two-basket or multi-basket rinsing has the advantage on the one hand that the force acting on the items to be washed by the water jet is relatively high, and thus the detachment of the food residues takes place relatively quickly.
  • high water and energy consumption and the associated high level of noise have proven to be disadvantageous in two-basket or multi-basket rinsing.
  • interchangeable basket rinsing In addition to dual-basket or multi-basket rinsing, so-called interchangeable basket rinsing is also known, in which the respective spray levels are specifically controlled in alternating operation. Although the low water and energy consumption and the associated low noise development are advantageous, the low mechanical effect of the water jet due to the alternating spraying processes on the items to be washed is disadvantageous and lead to an extension of the washing program runtime.
  • the object of the present invention is therefore, while maintaining the washing performance, to reduce both the washing program running time of a dishwasher and the noise development caused by the impacting water.
  • washing method according to the invention with the features according to claim 1 or with the dishwashing machines according to the invention according to claim 5.
  • Advantageous developments of the invention are characterized in the subclaims.
  • a substantial period of the washing program runtime is divided into a plurality of sub-time units, with essentially each sub-time unit consisting of at least two time sections and with washing liquid flowing through all the spray devices during a first time section and during a second Only the lowermost or the uppermost of the spraying devices is flowed through by washing liquid.
  • two time periods are provided in a sub-time unit, in which the action by the upper and the lower spraying device alternate.
  • the first time period advantageously borders directly on the second time period.
  • the length of the respective time segments can be determined in accordance with the respective wash program selection.
  • the second time period in which only the bottom of the spraying devices is flushed with washing liquid is expediently longer than in the case of a wash program in which the washware located in the upper basket only is insignificantly less dirty than the items to be washed in the lower basket, so that the first and second time periods are essentially of the same length in this case.
  • the washing method according to the invention when using the washing method according to the invention, in the second period, while only the lowermost or uppermost of the spraying devices are flushed with washing liquid, the items in the lowest or uppermost crockery basket are subjected to a higher mechanical hydropower, so that the cleaning performance for those in the lower or upper crockery basket existing wash ware is significantly increased.
  • the running time of the washing program is reduced and by at least temporarily washing the basket, with only the lower spraying device being actuated, the noise development is advantageously reduced.
  • the rinsing method according to the invention is intended for use, it has been possible to reduce the rinsing program runtime of the dishwasher as well as the noise that is caused by the impacting water while maintaining the rinsing performance.
  • Fig. 1 shows a variant of the flushing method according to the invention with only two time periods, so that a lower basket rinsing and a two-basket rinsing is carried out and
  • FIG. 2 shows an embodiment variant of the flushing method according to the invention during a complete flushing program with several time periods, so that a lower basket flush, two basket flush and upper basket flush are carried out.
  • the washing program running time t is plotted on the X axis and the noise development dB to be measured during the washing program is plotted on the Y axis.
  • the washing program runtime 4 is divided into an essential time period 5, which in turn is divided into a plurality of sub-time units 3.
  • the lengths of the sub-time units 3 depend on the respective wash program setting, which in turn depends on the degree of soiling or the choice of temperature.
  • the sub-time unit 3 is divided into a first time period 2 and a second time period 1 a, which directly adjoin one another. After the end of the time period 2, a time period 1 a begins again, at the end of which another time period 2 follows.
  • the length of the first or second time period 2, 1a depends on the duration of the washing program.
  • the noise generated by the spray devices changes in the respective time sections 2, 1a, with washing liquid being applied to the upper and lower basket simultaneously in the time section 2 and thus a higher noise level B being present, while in the time section 1a only washing liquid is applied to the lower basket via the spray device and therefore the noise level only reaches level A.
  • a plurality of time periods 5 can begin and end during the washing program runtime 4, depending on the respective washing program. By selecting such a program, it is therefore possible to assign different characteristics to the different washing programs by selecting the washing times.
  • the rinsing liquor conveyed by the circulating pump is passed into the respectively activated pipe sections via a water separator, which is not explained in greater detail, and which is controlled by the respective rinsing program, in order to flow through the spraying devices or spraying device in accordance with the rhythm shown.
  • a complete washing program sequence with two variants is shown in the diagram according to FIG. 2, the respective washing program sections being identified by means of Roman numerals.
  • the sub-time unit 3 is divided into time sections 1a and 1b, so that a so-called interchangeable basket rinsing is carried out between the lower and upper basket.
  • this wash program phase I two noise levels A and A * are reached, with A reflecting the level of noise generated in the lower basket and A * reflecting the level in the upper basket.
  • the wash program phase I follows the wash program phase II in which the washing liquor is heated up.
  • the wash program phase III In which all the spray devices are acted on with rinsing liquid and thus the noise level B is reached.
  • the wash program phase Na is used, for example, for other countries, such as in particular for the USA, to heat up the washing liquid, followed by the washing program phase IV, in which a distinction is made between two-basket washing and single-basket washing for cleaning, so that the time segments 2 and 1a follow each other.
  • rinsing phase of intermediate rinsing V follows, in which periods 1a and 1b are carried out alternately, and finally, after the rinse aid has been added, rinsing program phase VI begins, in which the items to be washed likewise follow the rhythm of the periods 1a and 1b are rinsed clear.

Abstract

L'objectif de l'invention est de réduire la durée du programme de lavage d'un lave-vaisselle et le bruit provoqué par l'impact de l'eau à l'intérieur de ce dernier, sans affecter le rendement de lavage dudit lave-vaisselle. A cet effet, le procédé de lavage selon l'invention, destiné à être mis en oeuvre dans des lave-vaisselle comprenant au moins deux unités de pulvérisation, consiste à diviser un intervalle de temps principal (5) de la durée du programme de lavage (4) en une pluralité de sous-unités de temps (3) de différentes longueurs. Pratiquement chaque sous-unité de temps (3) est constituée d'au moins deux laps de temps (1a, 1b, 2). Pendant un premier laps de temps (2), le liquide de lavage passe à travers toutes les unités de pulvérisation, et, pendant un deuxième laps de temps (1a, 1b), il traverse uniquement l'unité de pulvérisation supérieure ou l'unité de pulvérisation inférieure. L'objectif de l'invention est également atteint au moyen de lave-vaisselle comprenant au moins deux unités de pulvérisation et permettant la mise en oeuvre dudit procédé de lavage.
