Therefore, the pulsator washing machine can realize three different washing actions, thereby meeting various washing demands of users.

When the washing machine is dehydrated, as shown in fig. 1, the water in the inner tub may be drained through the drain valve 7, and then the clutch 6 may be switched to the first station, so that the inner tub 1 and the pulsator 2 rotate synchronously. The rotational speed during dehydration is faster and the rotational speed during washing is slower. Wherein, the drain valve 7 can be connected with a drain motor 8, and the control unit of the washing machine controls the opening and closing of the drain valve 7 by controlling the drain motor 8.

In various implementations of the clutch 6, for example, an electromagnetic clutch 6 with three stations may be selected, in one embodiment of the present application, as shown in fig. 2 and 3, the clutch 6 includes a fixing frame 61, a connector 62 and a switching device 63, the dewatering shaft 5 is disposed on the fixing frame 61 in a penetrating manner and rotates relative to the fixing frame 61, the connector 62 is disposed on the dewatering shaft 5 in a driving manner, the connector 62 can slide along an axial direction of the dewatering shaft 5, torque can be transmitted between the connector 62 and the dewatering shaft 5, an upper end face of the connector 62 is provided with an upper engaging tooth 621, a lower end face of the connector 62 is provided with a lower engaging tooth 622, the driving device 3 includes a rotor 31 disposed below the fixing frame 61, the rotor 31 is in driving connection with the washing shaft 4, the connector 62 is disposed between the rotor 31 and the fixing frame 61, an upper end face of the rotor 31 is provided with a rotor engaging tooth 311, a lower end face of the fixing frame 61 is provided with a fixing tooth 611, and the switching device 63 can drive the connector 62 to slide along the dewatering shaft 5. When the clutch 6 is switched to the first station, as shown in fig. 4, the switching device 63 drives the connector 62 to slide to the first position, and the lower engaging teeth 622 of the connector 62 engage with the rotor engaging teeth 311 of the rotor 31, so that the connector 62 connects the rotor 31 and the dewatering shaft 5 in a driving manner, and the rotor 31 can drive the dewatering shaft 5 and the washing shaft 4 to rotate synchronously; when the clutch 6 is switched to the second station, as shown in fig. 5, the switching device 63 drives the connector 62 to slide to the second position, and the upper engaging teeth 621 of the connector 62 are engaged with the fixing teeth 611 of the fixing frame 61, so that the connector 62 is locked by the fixing teeth 611 of the fixing frame 61, and the dewatering shaft 5 is locked, and at this time, when the rotor 31 drives the washing shaft 4 to rotate, the dewatering shaft 5 and the inner tub do not rotate; when the clutch 6 is switched to the third station, as shown in fig. 3, the switching device 63 drives the connector 62 to slide to the third position, the connector 62 is not in contact with the rotor 31 and the fixing frame 61, the connector 62 is in the middle suspended position and is not limited by rotation, so that the inner tub is in a free state, and when the rotor 31 drives the washing shaft 4 to rotate, the inner tub can realize delayed reverse rotation. The clutch 6 can realize the switching of three stations, and has simple structure and stable transmission.

Specifically, as shown in fig. 2, the arrangement positions of the washing shaft 4 and the dehydrating shaft 5 may be such that the washing shaft 4 is disposed through the dehydrating shaft 5 in the axial direction, the washing shaft 4 is rotatable with respect to the dehydrating shaft 5, the connector 62 is connected to the dehydrating shaft 5 by a first spline transmission extending in the axial direction of the dehydrating shaft 5, and the rotor 31 is connected to the washing shaft 4 by a second spline transmission extending in the axial direction of the washing shaft 4. The structure can realize the coaxial rotation of the inner barrel and the pulsator 2, and saves the arrangement space of the washing shaft 4 and the dewatering shaft 5.

The movement and the resetting of the connector 62 may be realized by the driving of the switching device 63, or the resetting of the connector 62 may be realized by a resetting member, as shown in fig. 2, and a resetting spring 64 may be disposed between the connector 62 and the fixing frame 61.

Therefore, when the inner cylinder 1 rotates, the water-shifting ribs 9 can wave the water flow in the inner cylinder, so that the fluidity of the water flow is enhanced, and the washing effect is improved.

In order to further improve the washing effect, as shown in fig. 1, the water-repellent ribs 9 are preferably provided in plural, and the water-repellent ribs 9 are distributed along the circumferential direction of the inner sidewall of the inner cylinder 1. Therefore, the fluidity of water flow can be further enhanced, and the washing effect is better.

The extending direction of the water-drawing rib 9 may be selected in various ways, for example, may extend along the axial direction of the inner barrel, or may be inclined with respect to the axial direction of the inner barrel, which is not limited herein. In order to enhance the water-repellent effect, the water-repellent ribs 9 may be provided as a solid structure, on which no holes are provided.
