Title:
INNER TUB FOR WASHING MACHINE
Document Type and Number:
Japanese Patent JP3510907
Kind Code:
B2
Abstract:
PURPOSE: To provide a uniform washing effect by a simple structure by providing a main body provided with many embossing projection parts formed so as to reduce frictional force from an upper part to a lower part and a bottom plate provided with a pulsator for constituting an inner tub together with the main body.
CONSTITUTION: On the inner peripheral surface of the main body 5a of this inner tub 5, the plural embossing projection parts 5c whose size is formed gradually small so as to reduce the frictional force from the upper part to the lower part are projectingly formed. Also, in the inner tub 5, plural elliptic embossing projection parts 5e for strength reinforcement formed long in a vertical direction are projectingly formed. Further, plural dehydration holes 5f are formed among the projection parts 5c and 5e. Then, the inner tub 5 of a stainless material is constituted of a cylindrical main body 5a where the projection parts 5c and 5e and the dehydration holes 5f are formed on the inner peripheral surface and the bottom plate 5b where a hub for supporting a clutch so as to be connected is connected to a lower surface. Thus, a laundry frictional effect uniformly is exerted at the upper and lower parts of the inner tub.
