Problems solved by technology

[0006] Often, clogging of the filter adversely affects the cleaning ability of the dishwasher, resulting in poor cleaning performance and indirectly increasing water and energy consumption
[0007] Another drawback of these filtration solutions is that both filtration and filter cleaning (if applicable) are driven by circulation pumps
Therefore, the design of the cleaning cycle is limited because the filtration process cannot be controlled independently
In addition, dirt particles are recirculated through the circulation system, not only causing clogging of the filter unit

Embodiment Construction

[0042] figure 1 A dishwasher 1 according to a first variant of the first embodiment of the invention is shown. The dishwasher comprises a washing tank 2 in which dirty dishes can be loaded into a dish basket (not shown) to be washed. Two spray arms 3 , 4 are arranged in the washing tank 2 . During operation of the dishwasher 1 , washing liquid is sucked out of the sump 5 by the circulation pump 6 and recirculated into the washing tank 2 via the spray arms 3 , 4 . The cleaning fluid passes through a flat fine filter 8 located in the storage tank 5 while circulating in the first circulation system 7 . In this variant, the fine filter 8 is part of the filter device 9 of the first circulation system 7 . However, the filtration in the first circulation system 7 relies on the actuation of the circulation pump 6 and does not utilize microfiltration. A coarse filter 25 may be provided in the sump 5 from which the washing liquid is drained.

Abstract

Dishwasher, comprising a first wash circulation system (7) with a wash circulation pump (6) to circulate washing liquid from a sump (5) to at least one spray device (3, 4) arranged in a wash tank (2), wherein a second circulation system (10) comprising a further pump and a filtration device (11) is provided to filter washing liquid independently from actuation of the circulation pump (6) of the first circulation system (7).

Description

technical field [0001] The invention relates to a dishwasher comprising a first rinsing circuit with a rinsing circulation pump for circulating rinsing liquid from a sump to at least one spray device arranged in the rinsing tank. Background technique [0002] In known dishwashers, washing liquid is usually drawn from a sump at the bottom of the washing tank, pumped by a circulation pump into a spray arm which distributes the washing liquid into the washing tank to remove Remove dirt from the dishes in the dish basket located in the slot. [0003] In order to prevent the redistribution of dirt onto the dishes, various filter arrangements are known. These filters separate dirt from the circulating cleaning fluid. Two basic approaches are known in the art. [0004] In one variant, the strainer or strainer is arranged on the outlet side of the circulation pump. Fine filters or even microfine filters can be used. However, there is a risk of filter clogging. Typically, a bac...
