Embodiment Construction

[0016] FIG. 1 shows a schematic perspective view of a flat sieve 1 which can be installed in the bottom region of the rinsing chamber of a dishwasher. In the middle, a central opening 2 is formed, into which opening a coarse / fine strainer can be fitted in a conventional manner. The rinsing liquid collected at the bottom or in the dishwasher sink passes through the holes of the planar sieve 1 into the cavity below it, from which a circulating pump draws the rinsing liquid, and the rinsing liquid Dispenses again via the spray arms to the items to be washed in the dishwasher compartment. The rinsing liquid flowing through the central opening 2 into the coarse / fine sieve either passes through the fine sieve of the coarse / fine sieve also into the cavity below the flat sieve 1 or reaches a drain In the extraction region of the empty pump, the empty pump extracts the extracted rinsing liquid from the dishwasher.

[0017] A recess 3 is formed in the rear region of the flat sieve 1 ,...

Abstract

The invention relates to a sieve device for a dishwasher, comprising a sieve area (2) and a plurality of holes that are formed within the sieve area. According to the invention, the holes in the sieve area are embodied with different sizes.

Description

technical field [0001] The invention relates to a sieve arrangement for a dishwasher, which is arranged in the bottom region of the dishwasher and which traps coarse dirt from the suction region of the circulation pump. Background technique [0002] In conventional flat sieves for dishwashers, all the sieve holes have the same diameter. If items to be cleaned are placed in the dishwasher with soil consisting of many dirt particles of the same size, this can lead to extensive clogging of the filter pores, when the dirt remains When the size is approximately within the range of the hole size described. This is the case, for example, in the case of coffee grounds, in which case the ground coffee particles are not broken down any further during the rinsing process, but which, depending on the grinding strength, have particle size within. Clogging of the flat filter by these dirt particles can lead to impaired rinsing results or rinsing operations. Contents of the invention ...
