Abstract: Large capacity is an important direction of the development of washing machine. The so-called large capacity washing machine is based on the situation of constant width, constant depth or little change of the whole machine. It mainly improves the capacity of the whole machine by increasing the diameter of the drum and optimizing the design of the parts in the depth direction of the whole machine. Because the width of cabinet is constant and the diameter of drum increases, the gap between the drum with the tub and the gap between the tub with the cabinet will be reduced. In this paper, through the system design and test of the width direction of the whole machine, the capacity of the whole machine is improved in the range of safety clearance.

Key words: Gap, Measurement, Width direction, Washing machine
