Problems solved by technology

[0005] However, according to the conventional dishwasher, since foreign matter keeps accumulating in the above-mentioned filter device when washing a plurality of tableware, the problem that the above-mentioned foreign matter causes the filter device to be clogged occurs.
[0006] In addition, since the foreign matter accumulated in the above-mentioned filter device acts as a flow resistance against the wash water, the flow rate and flow velocity of the wash water passing through the above-mentioned filter device are reduced.
As a result, as the amount of washing water supplied to the above-mentioned washing water injection device decreases, the cleaning performance of the dishwasher also decreases, thereby causing a problem that the washing water suction unit that sucks the washing water is also overloaded.
[0007] Moreover, if the foreign matter continues to accumulate in the filter device, the above-mentioned foreign matter will stick to at least one side of the filter, making it difficult to remove, and there will also be a problem that a bad smell will be generated inside the cleaning space due to the decay of the foreign matter.
