[0002] A dishwasher is a device used to automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. In the process of cleaning tableware, in addition to washing away oil residue, it is often necessary to sterilize and disinfect the tableware. However, most existing dishwashers only have the ability to clean tableware. A small number of dishwashers that can disinfect tableware use high-temperature steam or ultraviolet light to sterilize the tableware.

[0003] Traditional sterilization modules rely on screws for fixing, which takes a long time to install and allows water to seep through the thread gaps, causing the module to fail under high-pressure spray conditions. Furthermore, vibration can easily cause the screws to loosen. In addition, existing dishwasher UVC sterilization modules use only UVC sterilization, which cannot decompose organic residues, requiring an additional spray rinsing step. Summary of the Invention
