Description

technical field

[0001] The invention belongs to the field of household appliances, and in particular relates to an observation window installation structure. Background technique

[0002] The clothes inlet of the existing drum washing machine is provided with an observation window, which is connected to the front plate of the drum washing machine through a hinge, which not only plays a role of sealing the washing machine to prevent the water in the drum from overflowing, but also helps the user to check the clothes in the drum. Observe the laundry condition. However, as an important part of the appearance design, the observation window of the drum washing machine is an important element of the appearance design. In the trend of appearance design, the diameter design of the observation window is getting larger and larger, and the front plate is likely to cause strength loss after being rounded. Therefore, it is necessary to solve the strength reliability problem in the desig...
