Problems solved by technology

However, when the items to be washed are small loads, due to the large difference between the load volume and the capacity of the inner cylinder, it is likely that even after multiple adjustments, the state of uniform distribution cannot be achieved, resulting in a dehydration success rate when washing small loads with existing washing machines The low problem will also greatly prolong the washing time due to multiple adjustments, and the waste of water resources will be caused by multiple water inflows

Embodiment 1

[0066] The washing machine described in this embodiment includes an inner tub for storing loads to be washed. An eccentric member is arranged on the wall of the inner cylinder, and the eccentric member can absorb water to increase its weight, and the rotation speed of the inner cylinder can be greater than the set rotation speed V 0 Lose water and lose weight.

[0067] like Figure 1 to Figure 8 As shown, in this embodiment, the eccentric member includes a housing 600 with a hollow chamber and a water-absorbing member 110 arranged inside the housing 600. Several water inlet holes 401 are provided on the housing 600, and the water-absorbing member 110 can absorb water to increase own weight.

[0068] In this embodiment, the water-absorbing member 110 is a water-absorbable material with a specific water absorption rate, such as a water-absorbing sponge.

[0069] Further, inside the housing 600 there is a partition plate 300 arranged perpendicular to the radial direction of th...

Embodiment 2

[0103] like Figure 9 As shown, this embodiment provides a control method for the washing machine described in the first embodiment above, the washing machine has a small-load dehydration program, and the small-load dehydration program specifically includes the following steps:

[0104] S1, the washing machine detects the eccentric value of the inner cylinder, and the eccentric value of the inner cylinder is less than L 1 , control the speed of the inner cylinder to rise to V 1 and last for a certain period of time;

[0105] S2, control the inner cylinder to reduce the speed and detect the eccentric value, the eccentric value of the inner cylinder is less than L 2 , control the speed of the inner cylinder to rise to V 2 and last for a certain period of time;

[0106] S3, control the inner cylinder to reduce the speed and detect the eccentric value, the eccentric value of the inner cylinder is less than the preset eccentric value L 0 , control the speed of the inner cylind...

Abstract

The invention belongs to the technical field of washing machines, and discloses a washing machine and a control method thereof. The washing machine comprises an inner barrel, an eccentric part is arranged on the barrel wall of the inner barrel, the eccentric part can absorb water to increase weight, and water loss weight reduction can be achieved when the rotating speed of the inner barrel is larger than the set rotating speed V<0>. According to the washing machine, the eccentric part capable of absorbing water to increase weight is arranged on the barrel wall of the inner barrel, so that whenthe washing machine washes a small load, the eccentric part capable of absorbing the water to increase weight can counteract at least part of eccentricity generated by the load in the barrel after water is drained, and the inner barrel can reach a balanced state so as to start dehydration; and in the dehydration process, when the rotating speed of the inner barrel is larger than the set rotatingspeed V<0>, the eccentric part and the load synchronously dehydrate, the balance state of the inner barrel is kept, and smooth dehydration is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine and a control method thereof. Background technique [0002] When the existing washing machine washes small loads, it is limited by the difference between the load volume and the capacity of the inner tub, and it is difficult for the load in the tub to form a uniform state in the tub after the drainage is completed. In this way, in the dehydration stage, the load in the cylinder tends to stick to one side of the cylinder wall under the action of inertia, resulting in a large eccentricity of the inner cylinder, which is easy to cause the outer cylinder to hit the cabinet or the washing machine during the dehydration process of the high-speed rotation of the inner cylinder The phenomenon of the whole machine shifting. As for the washing machine with its own eccentric protection program, the rotation speed of the inner drum may not be raised to...
