Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a dishwasher with a dynamic water circulation and separation function. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. It achieves cleaning by spraying water under high temperature and pressure to thoroughly rinse the surface of the tableware, greatly improving efficiency. The high temperature environment effectively kills bacteria, ensuring the tableware is clean and hygienic.

[0003] Against the backdrop of global water scarcity and increasingly stringent environmental regulations, the dynamic separation technology of circulating water in commercial dishwashers is experiencing rapid development. According to data from the United Nations Environment Programme, the catering industry accounts for 12% of global freshwater consumption, and traditional dishwashers consume as much as 15 to 20 liters of water per cycle, which is quite wasteful. As countries successively introduce stringent emission standards (such as the EU's EU2021 / 1187, which reduces the COD limit for catering wastewater to 50 mg / L), the industry urgently needs breakthrough water-saving technologies.
