Example two
Referring to fig. 3-4, the present embodiment provides a washing machine, including a casing 10, wherein a damper assembly according to the first embodiment is disposed in the casing 10, and a first driving device 300, a flywheel 400 and a second driving device 600 are disposed between an outer tub 100 and the casing 10.
Specifically, the upper part of the casing 10 of the present embodiment is further provided with a plurality of fixing tables 11, and the fixing tables 11 are connected to the outer tub 100 through a hanger rod 12, so that the outer tub 100 is suspended in the casing 10 through the hanger rod 12.
Alternatively, four fixing tables 11 may be provided in the cabinet 10, and the four fixing tables 11 are provided at four corners of the cabinet 10, respectively. The four fixed tables 11 are each connected with a boom 12, and the boom 12 can be connected to the corresponding fixed table 11 by means of a hanger 13, for example. The boom 12 and the outer tub 100 may be connected by a fastener such as a screw. Damping parts such as springs may be provided in the hanger rod 12 so as to facilitate damping of vibration of the outer tub 100.
In this embodiment, the upper end of the casing 10 is further provided with a cover 14, and the cover 14 can be opened or closed relative to the casing 10, so that a user can conveniently open the cover 14 to take and put clothes, or close the cover 14 to wash the clothes.

The feet 15 may be provided, for example, in four, at the four corners of the washing machine, respectively, to level the washing machine by adjusting the height of the different feet 15.
Because the damping component of the first embodiment is provided in the washing machine of this embodiment, when the washing machine is dehydrated, the inner tub 200 is driven by the first driving device 300 to rotate, if the load weight of the inner tub 200 is uneven, the inner tub 200 will drive the outer tub 100 to vibrate simultaneously, so that the outer tub 100 is offset, the outer tub 100 offset will drive the second driving device 600, the shaft sleeve 310 and the inner ring of the aligning bearing 500 to be offset, and the outer ring of the aligning bearing 500 and the flywheel 400 will not be offset temporarily; since the second driving device 600 is further provided, the second driving device 600 drives the flywheel 400 to rotate to generate angular momentum, so that the offset of the outer tub 100 can be reduced by using the angular momentum of the flywheel 400, thereby reducing the vibration amount of the washing machine during dehydration.
Example III
Referring to fig. 5, the present embodiment provides a damping method for a washing machine, the washing machine including a damping assembly according to the first embodiment, the method including:
step S110: and acquiring a washing instruction.
For example, a control panel of the washing machine may be provided with a plurality of different program buttons, such as standard, quick washing, down jackets, wool, and strong washing, and each button corresponds to an operation program, and a complete operation program may generally include a plurality of different operation states such as water inlet, washing, water drainage, and dehydration, and a user inputs a washing instruction to the washing machine after pressing any button.
Step S120: based on the washing instruction, an initial load weight and laundry material in the inner tub are obtained.
For example, an initial load weight of the inner tub may be obtained before the water is fed into the washing machine to determine the water feed amount and the detergent feed amount. The clothing material can be the clothing material of user input, for example can set up the button of multiple material on washing machine's control panel, and the user can press the button of corresponding material to the material of input clothing. The water absorption of different materials has larger difference, and each material has a fixed residual water proportion after water is discharged. For example, cotton fabrics have high water absorption, high initial weight before dehydration, and high eccentric probability; the chemical fiber fabric has low water absorption rate, easy dehydration and small eccentric probability; and the fabrics such as outdoor clothes, outdoor jacket and the like have poor water permeability, are easy to pocket water and are more easy to eccentric, so that the initial running speed of the flywheel is required to be increased.
Step S130: the load weight of the inner tub after the end of the draining is determined based on the initial load weight in the inner tub and the laundry material.
For example, the main control module of the washing machine may store the load weight of the inner tub after the water discharge is completed under different load weights and laundry materials in advance.
Step S140: the initial rotational speed of the flywheel is determined based on the load weight of the inner tub after the water discharge is completed.
For example, the main control module of the washing machine may store in advance the initial rotation speed corresponding to the flywheel under different load weights and clothes materials.
Step S150: the operating state of the washing machine is obtained.
The main control module of the washing machine can acquire the current running state of the washing machine in real time.
Step S160: if the running state of the washing machine is drainage, the flywheel is controlled to rotate at the initial rotating speed after the preset time.
When the washing machine is operated in a water discharge state, the main control module of the washing machine may send a control command to the second driving device after a preset time, so that the second driving device drives the flywheel to rotate at a corresponding initial rotation speed. The preset time can be set according to the requirement.
Since the drainage state and the dehydration state of the washing machine are generally two states of continuous operation, and since the load weight in the inner tub is maximum at the time of initial dehydration of the washing machine, the driving force of the output of the first driving means is also maximum, and at this time, the vibration amount of the inner tub and the outer tub is maximum, and the offset amount generated by the outer tub is also maximum. If the flywheel is started after the outer barrel is deviated, the deviation amount of the outer barrel cannot be reduced in advance, so that the effect is poor. Therefore, after the preset time is run in the drainage state, the flywheel is controlled to rotate in advance before the dewatering program is run, so that the offset of the outer tub can be better resisted, and the offset of the outer tub during dewatering of the washing machine is reduced.
In an alternative implementation, the method of this embodiment further includes:
obtaining the output current of the second driving device; the rotational speed of the flywheel is adjusted based on the output current of the second drive means.
Because the load weight in the inner barrel is continuously changed when the washing machine is in different times under the dewatering program, the eccentric amount of the flywheel and the outer barrel under the corresponding time can be judged by detecting the output current of the second driving device.
If the output current of the second driving device increases, the offset of the outer barrel increases, so that the rotating speed of the flywheel can be increased to offset the offset of the outer barrel.
If the output current of the second driving device is reduced, the offset of the outer barrel is reduced, so that the rotating speed of the flywheel can be reduced, and the energy consumption is reduced. Specifically, the outer barrel can be lowered in a step manner, for example, the outer barrel can be lowered for 10 circles/min, the outer barrel can be lowered continuously if no obvious eccentricity occurs, and the rotating speed can be stopped to be lowered if the eccentricity exists.
