Abstract: An air supply system for a washing apparatus, and a washing apparatus having same including: a fan; an air duct chamber, a first air passage duct and a second air passage duct, which are spaced apart from each other, are arranged in the air duct chamber; an air supply pipe, where the air supply pipe can be in communication with an exhaust port of the fan by the first air passage duct, and the air supply pipe is positioned so as to be able to supply air to a window pad of a washing apparatus by running the fan. With this system, residual water in the window pad can be effectively removed to prevent bacteria breeding and odor generation caused by residual water; also, moist air can be discharged out of the washing apparatus in a timely manner to prevent the moist air from causing pipeline pollution and component erosion.

Abstract: Provided are a front door assembly of a drum washing machine and a drum washing machine. The front door assembly includes an observation bowl glass. The observation bowl glass includes an edge portion, a central portion, and a transition portion connecting the edge portion with the central portion. The central portion protrudes relative to the edge portion. The front door assembly further includes at least one protrusion. The at least one protrusion is arranged at a junction of the central portion and the transition portion. A protruding direction of the at least one protrusion is the same as a protruding direction of the central portion relative to the edge portion.
