[0002] A dishwasher with automatic slag removal function is a kitchen appliance that automatically completes the cleaning, disinfection, drying and storage of tableware through the combined action of mechanical and chemical processes. It is widely used in homes, restaurants, hotels and other settings.
[0003] In existing technology, household dishwashers with automatic food waste removal functions clean dishes using a circulating water flow. To obtain a relatively clean circulating water flow, impurities are primarily filtered through a filtration unit. After the water flows through the filtration unit, impurities in the water are filtered onto the filter screen, and food residue is also filtered out with the water flow. Inevitably, food residue and impurities will remain on the filter screen, especially on the finer filter screens, where some more difficult-to-clean food residue and impurities may remain. These food residues and impurities are difficult to remove, and if not cleaned promptly, they can breed bacteria or produce odors on the filter screen, leading to secondary contamination of the dishes.
[0004] Therefore, it is necessary to provide a new dishwasher with automatic slag removal function to solve the above-mentioned technical problems. Utility Model Content
