[0002] As people's pursuit of quality of life continues to improve, the popularity and intelligence of home appliances are also increasing, and dishwashers are entering more and more families. Generally speaking, a light source is set inside the dishwasher to provide light when the door is opened, so as to facilitate the storage and retrieval of tableware such as bowls and chopsticks in the dishwasher tank. However, for dishwashers with larger capacity and deeper tanks, ordinary light sources cannot provide enough light for the space in the tank.

[0003] When installing the existing downlight structure, sealants are mostly used at the joints to achieve overall sealing of the downlight. The overall sealing method is relatively simple. When the sealant is partially damaged, it is easy for water vapor in the dishwasher to enter the downlight through the gap and cause the lamp beads to be damaged by moisture. Therefore, a downlight structure is needed to assist in solving this problem. Utility Model Content
