Description

Technical Field

[0001] This utility model belongs to the field of dishwasher valve anti-clogging technology, and specifically relates to an anti-clogging device for a water inlet converter valve of a dishwasher. Background Technology

[0002] A dishwasher is a household or commercial appliance used to automatically clean dishes, cookware, and other kitchen utensils. It removes food residue and grease by spraying high-pressure hot water and detergent, followed by rinsing and drying. During operation, dishwashers are connected to a water source via pipes. This water source often contains impurities of varying sizes. These impurities can accumulate inside the dishwasher's inlet valve as it passes through. Over time, this buildup can obstruct water flow or cause blockages, leading to clogging of the inlet valve. This blockage can affect the dishwasher's normal operation, causing water inlet abnormalities, triggering equipment errors and shutdowns, and impacting user experience. Furthermore, the common design using external filters presents maintenance challenges.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
