Abstract: An anti-overflow device at a drum water injection port for a drum washing machine comprises a water flow baffle. The water flow baffle extends along an outer drum to an inner drum and is installed at the water injection port, and water flow is blocked to run back into the water injection port along with the inner drum at a high speed. The anti-overflow device further comprises a blocking rib, and the blocking rib is arranged on the inner side of the water injection port and close to the outer drum. The drum washing machine comprises the anti-overflow device at the drum water injection port. The principle of fluid mechanics is adopted in the anti-overflow device at the drum water injection port, the change of liquid flow in the drum is realized, and the anti-overflow effect is good.

Abstract: A door for a drum washing machine comprises an inner frame, a glass tub, a middle frame, a window screen and an outer frame which are arranged sequentially from the inner side of the door to the outer side of the door. The middle frame is in welded connection with the inner frame, the glass tub is clamped between the inner frame and the middle frame, the outer frame is in snapped connection with the middle frame and/or the inner frame, and the window screen is clamped between the outer frame and the middle frame. The window screen is free of snap jaw, so that the structure is simplified, and production of the window screen is accelerated.

Abstract: An outer drum of a washing machine is provided, and relates to the technical field of washing machines. Two opposite side walls of the outer drum of the washing machine are formed as non-circular surfaces to avoid collision with side plates of a housing. A washing machine having the above outer drum is further provided.
