Abstract

The present invention relates to a dishwasher (1) comprising a washing chamber (3) arranged for holding soiled items to be washed, a filter (11), a circulation pump (37), which is operable to create a circulation flow (43) of washing liquid through the washing chamber (3), through the filter (11) and back to the washing chamber (3). The washing chamber (3) is such arranged that, when the flow (43) of washing liquid passes through the washing chamber (3), soil (31) is released from the items to be washed and caught in the flow (43). The filter (11) is such arranged that, when the flow (43) of washing liquid with soil (31) passes through the filter, soil (31) is separated from the flow (43) of washing liquid and caught at the filter (11). The dishwasher (1) further comprises a soil trap (15), which is located separate from the circulation flow (43), and a soil removing unit (25, 26) comprising a transport unit (25) for transport of the soil (31) caught at the filter (11) into the soil trap (15).

Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a dishwasher comprising a washing chamber arranged for holding soiled items to be washed, a filter and a circulation pump. The circulation pump is operable to create a circulation flow of washing liquid through the washing chamber, through the filter and back to the washing chamber. The washing chamber is such arranged that, when the flow of washing liquid passes through the washing chamber, soil is released from the items to be washed and caught in the flow. The filter is such arranged that, when the flow of washing liquid with soil passes through the filter, soil is separated from the flow of washing liquid and caught at the filter.BACKGROUND ART A problem with dishwashers of the above mentioned type is that the filter has a tendency to clog by soil particles that are caught at the filter. Therefore, conventional dishwashers are normally equipped with two filters, i.e. a fine-mesh filter and a coarse-mesh filter. Th...
