One end of the outer cylinder 200 is sealed as an outer cylinder bottom, the other end of the outer cylinder 200 is provided with an opening to form an outer cylinder opening, and the outer cylinder opening is connected with the front plate of the shell 100 through the window pad 500, so that the distance between the outer cylinder opening and the front plate of the shell can be sealed by the window pad 500, and the outer cylinder 200 can be vibrated without interference with the shell 100 by utilizing the telescopic deformation of the window pad 500. In addition, the casing 100 is provided with a door 400 which can be opened and closed, and the door 400 is matched with the window pad 500, so that the closed door 400 can correspondingly close the cylinder opening of the outer cylinder, and a water containing cavity is formed in the outer cylinder 200.

In order to facilitate the user to observe the working condition inside the outer cylinder, an observation window made of transparent glass is generally disposed on the door 400, at least a portion of the observation window protrudes toward the inner side of the outer cylinder, so that a glass protruding portion extending into the hollow region of the window pad is formed on the door, and a gap is formed between the glass protruding portion and the window pad 500. In order to meet the requirements of the existing drum washing machine for the design, the center of the observation window is generally higher than that of the outer drum 200, so that the gap between the observation window glass and the observation window pad 500 is relatively large, and the laundry washed in the drum is easy to drop into the gap.

After the clothes fall into the gap, the clothes are clamped by the gap, and the inner cylinder 300 which is still rotating still drives other clothes to lift, so that the clothes are worn, even the clothes are damaged, and the like.

In order to realize the vibration connection with the outer cylinder opening, the window pad 500 is generally provided with wrinkles capable of generating elastic deformation, and clothes entering a gap between the observation window glass and the observation window pad are easily clamped by the wrinkles, so that the abrasion of the clothes is further increased, and even when the clamped clothes are too much, the motor can not drive the inner cylinder 300 to rotate.

In view of this, the present invention has been made.
