When the detector detects that no water flows through the drain valve, the motor is controlled to rotate slowly, and the process is repeated. A time threshold is set at which the body 4 is rotated all the time, and if water outflow is not detected all the time, it is considered that dehydration is completed.

In some embodiments, the cylinder 4 comprises a cylinder, the axis of the cylinder is arranged horizontally, one end of the cylinder is connected with the door body 5 in a sealing manner, and the other end of the cylinder is arranged on the bracket component; the drainage device 8 is arranged on the side wall of the cylinder 4.

The door body 5 is directly connected with the cylinder in a sealing way and rotates along with the cylinder, so that the door seal is cancelled, and the formation of residues on the door seal is avoided.

In some embodiments, the door body 5 is provided with a water inlet device at the axial position, and a water outlet end of the water inlet device is communicated with the inside of the cylinder 4.

In order to conveniently inject water into the cylinder, the water inlet device is arranged on the door body 5 with the axis, and water can be fed without being influenced by the rotation of the cylinder.

In some embodiments, the water inlet device includes a water inlet pipe 52 and a bearing 51, and the bearing 51 is sleeved between the water inlet pipe 52 and the door body 5.

The concrete structure of the water inlet device can adopt a water inlet pipe 52 combined with a bearing 51, a hole is formed in the circle center position of the door body 5, the bearing 51 is installed on the inner side of the water inlet pipe 52, and the inner ring of the bearing 51 is installed together with the hole.

The rotating shaft 10 is a hollow shaft for installing the electric wire and the signal transmission line of the drainage device 8. The drainage device 8 is fixed on the side wall of the cylinder 4 and consists of a drainage valve and a flowmeter. The door body 5 is used for sealing the cylinder body 4 and water inlet and plays a role of an original water box. The bearing 51 seat of the rotating shaft 10 and the roller bracket 6 are designed into a whole and play a role of supporting the roller. The sewage collecting device 3 is fixed with the roller bracket 6 and is stationary. The first compression spring 7 and the second compression spring 9 play roles in vibration reduction and vibration isolation.

The door body 5 is arranged at the throwing opening of the cylinder body 4 and rotates along with the cylinder body 4, so that the aim of sealing the cylinder opening is fulfilled. The door body 5 is of a hollow structure, water can be stored in the door body, and water outlets 53 are formed in the periphery of the part, extending into the barrel 4, of the door body 5, so that water can conveniently flow into the barrel 4. A hole is formed in the circle center position of the door body 5, a bearing 51 is installed on the inner side of the water inlet pipe 52, and the inner ring of the bearing 51 is installed with the hole in the door body 5. The design can ensure that the water inlet pipe 52 can not be wound on the drum body 4 to cause accidents when the drum body 4 rotates, and meanwhile, the water inlet of the washing machine is not influenced.

When the drain 8 is rotated below the liquid level, the water flows along the drain into the waste water collecting device 3 and is then discharged. In the process, the flow meter of the drainage device 8 detects that water flows through the drainage valve, and sends a signal to control the direct drive motor 1 to brake, so that the barrel 4 stops at the current position and does not rotate until the flow meter does not detect that liquid passes through the drainage device 8. When the flowmeter detects that no water flows through the drain valve, a signal is sent to control the direct drive motor 1 to slowly rotate again, and the process is repeated. A time threshold is set, the cylinder body 4 rotates all the time, if the flow meter cannot detect the water outflow all the time, the cylinder is considered to be anhydrous, and the water drainage is finished.

The second pressure spring 9 is arranged on the side surface of the roller bracket 6, forms a certain included angle with the horizontal plane and can be regarded as a negative stiffness element. When the washing machine operates, vibration is transmitted to the bearing 51 seat firstly and then to the whole drum support 6, the first pressure spring 7 is subjected to vertical pressure, and the second pressure spring 9 is subjected to a horizontal component force more. Since the second compression spring 9 is a negative stiffness elastic element, the overall stiffness of the damper system is lower than the overall stiffness of the first compression spring 7, but the supporting force generated by the damper system is greater than the total reaction force generated by the compression of the first compression spring 7. The whole system keeps smaller rigidity under the condition of obtaining larger supporting force, and a better vibration isolation effect is achieved.
