Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically an automatic cleaning dishwasher. Background Technology

[0002] Traditional dishwashers mainly rely on a combination of high-pressure spraying and high-temperature water rinsing to clean dishes.

[0003] While this method can effectively remove most stains, it is often less effective at cleaning stubborn stains such as dried grease, limescale, or sticky food residue. These stubborn stains tend to remain on the surface or in the crevices of dishes, requiring manual cleaning by the user. This not only increases the user's workload but also reduces the automation level of the dishwasher and the user experience. In addition, during the cleaning process, food residue that falls off in traditional dishwashers can easily scatter with the water flow, leading to secondary pollution or clogging of the drainage system.

[0004] Therefore, we propose an automatic cleaning dishwasher. Utility Model Content
