Preferably, the base assembly is provided with a dehydrating shaft 20, the dehydrating shaft 20 is connected to the inner tub 10, a central axis of the inner tub 10 extends in a vertical direction, and the inner tub 10 is rotatable about its central axis. Specifically, one end of the dewatering shaft 20 is connected with a driving device on the base assembly, the other end of the dewatering shaft is connected with the bottom of the inner barrel 10, the inner barrel 10 is arranged inside the outer barrel and can freely rotate, water outlet holes are formed in the bottom and the side wall of the inner barrel 10, and the water outlet holes penetrate through the wall of the inner barrel 10.

Thus, according to the washing machine 100 of the embodiment of the present invention, the driving device drives the inner tub 10 to rotate through the dehydrating shaft 20 by directly connecting the dehydrating shaft 20 with the inner tub 10, and the water drops on the laundry are removed by using the centrifugal force provided by the high-speed rotation of the inner tub 10, so that the washing machine 100 can dehydrate the laundry while having a washing function, the use function of the washing machine 100 is increased, the stability between the inner tub 10 and the dehydrating shaft 20 is increased, the structural separation of the inner tub 10 and the dehydrating shaft 20 due to the excessive stress is prevented, and the use time of the inner tub 10 and the dehydrating shaft 20 is prolonged.

Specifically, the length of the washing machine 100 in the horizontal direction is a and the width is b, and the height of the washing machine 100 in the vertical direction is h, where h=0.618× (a+b) ×k, a+b+h <1.1m,0.8< k <1.2.

In other words, the length a, the width b and the height h of the washing machine 100 satisfy h=0.618× (a+b) ×k, a+b+h <1.1m,0.8< k <1.2, and thus, the length, the width and the height of the washing machine 100 can be optimally designed, on one hand, the occupied space of the washing machine 100 can be reduced, so that the washing machine 100 can be conveniently moved and carried, the convenience of use of the washing machine 100 can be improved, and on the other hand, a plurality of different types of washing machines 100 can be produced according to the design proportion, so as to meet the needs of different crowds.

The bottom of the inner tub 10 is provided with a boss 11 protruding downwards, the boss 11 is directly connected with the dehydrating shaft 20, specifically, the inner tub 10 is connected with the dehydrating shaft 20 through the boss 11, the boss 11 is arranged at the bottom of the inner tub 10, the boss 11 is provided with a connecting piece for fixing the dehydrating shaft 20, in the dehydrating process of the washing machine 100, the driving device drives the dehydrating shaft 20 to rotate, the dehydrating shaft 20 drives the boss 11 to rotate, and the inner tub 10 is driven to rotate together in the rotating process of the boss 11.

The dewatering shaft 20 and the inner barrel 10 are connected into a whole through the boss 11, so that the normal dewatering function of the washing machine 100 can be ensured, the relative sliding between the dewatering shaft 20 and the inner barrel 10 can be prevented, the inner barrel 10 can be prevented from being damaged when the torque of the dewatering shaft 20 is overlarge, the strength of the inner barrel 10 is improved, and the service life of the inner barrel 10 is prolonged.

Preferably, the boss 11 is formed into a circular boss 11, the cross section of the boss 11 is circular, and is connected to the bottom of the circular inner barrel 10, so that the stability of connection between the boss 11 and the inner barrel 10 can be improved, the shaking of the inner barrel 10 and the boss 11 during high-speed rotation can be prevented, the stability of the washing machine 100 in the working process is improved, the failure rate of the washing machine 100 is reduced, the noise in the dewatering process of the washing machine 100 is weakened, and a comfortable experience environment can be provided for a user.

Advantageously, the boss 11 is arranged coaxially with the inner tub 10, that is, the central axis of the inner tub 10 coincides with the central axis of the boss 11.

The boss 11 and the inner tub 10 focus that coaxial setting all fall on the center pin, can the at utmost reduce the swing when inner tub 10 and boss 11 rotate when the rotation of dehydration axle 20 drive inner tub 10, increase the rotatory stability of inner tub 10, prevent that inner tub 10 from rocking the outer tub and other equipment that damage washing machine 100, from this, can improve the rotational speed of inner tub 10, the centrifugal force that the increase inner tub 10 produced, increase washing machine 100's dehydration efficiency, and then shorten the dehydration time, can also reduce the damage of boss 11 to dehydration axle 20 simultaneously, the bending moment of dehydration axle 20 during operation reduces, increase the live time of dehydration axle 20.

Optionally, the radial dimension of the inner tub 10 is L, and the radial dimensions of the boss 11 are M, where L and M satisfy: l > M >1/2L, that is, the radial dimension of the boss 11 at the bottom of the inner tub 10 is affected by the radial dimension of the inner tub 10, the edge of the boss 11 cannot exceed the bottom edge of the inner tub 10, and the boss 11 cannot be too small or otherwise be disabled, the diameter of the boss 11 is smaller than the diameter of the inner tub 10 and larger than the radius of the inner tub 10.

Therefore, by optimizing the sizes of the inner tub 10 and the boss 11 of the washing machine 100, not only the volume of the washing machine 100 can be prevented from being increased due to the overlarge occupation space of the radial size of the boss 11, but also the radial size of the boss 11 can be prevented from being too small to lose effect, the inner tub 10 is driven to rotate at a high speed by the dewatering shaft 20 in the working process of the washing machine 100, the moment between the dewatering shaft 20 and the boss 11 is large, the boss 11 is easily damaged due to the undersize of the boss 11, the dewatering shaft 20 is easily separated from the inner tub 10, and the normal operation of the washing machine 100 is affected. Therefore, the boss 11 with reasonable design size not only can ensure the normal operation of the washing machine 100, but also can reduce the production cost and the failure rate of the washing machine 100.

Preferably, the axial height of the boss 11 is 1-5mm, which not only ensures stable connection of the dehydrating shaft 20 and the inner tub 10, but also shortens the distance between the dehydrating shaft 20 and the inner tub 10, thereby reducing the volume of the washing machine 100 and providing convenience for movement and carrying of the washing machine 100.
