Abstract (en)
Laundry treating appliance including a hollow mechanism (4, 6) including a first member and a second member, the first member having a first flat surface before assembly, the second member having a second flat surface before assembly, the first member and the second member being fixedly connected through friction welding of the first flat surface and the second flat surface to form the hollow mechanism, and at least one of the first flat surface and the second flat surface having protruding welding ribs (7) that constitute edges of several closed geometric units (70) joined to each other. The welding ribs (7) that form the closed geometric units (70) joined to each other have a longer welding line, a larger area, and higher welding strength, thus achieving a firmer and more reliable connection between the first member and the second member and higher tightness of welding points.
