The pulsator assembly 100 according to one embodiment of the present invention includes a pulsator body 11, a driver 12, and a plurality of water-repellent ribs 13. The periphery of the impeller body 11 is provided with a water inlet which is communicated with the inlet of the flow channel, the middle part of the impeller body 11 is provided with a water outlet 101, and the water outlet 101 is communicated with the outlet of the flow channel.
Further, the driver 12 is used for driving the pulsator body 11 to rotate, for example, the driver 12 may be a motor. A plurality of water stirring ribs 13 are arranged on the upper surface of the impeller body 11. The pulsator assembly 100 is configured to form a water flow by rotating a portion of water by the water stirring rib 13 when the driver 12 drives the pulsator body 11 to rotate, and to eject a portion of water entering the first or second flow passage 102 or 103 from the water outlet 101 to form a water flow.

According to an alternative embodiment of the present invention, the water outlet 101 includes a plurality of water outlets 101, and the plurality of water outlets 101 are communicated with the outlet of each flow channel. For example, a water passing cavity is provided between the outlets of the plurality of flow channels and the plurality of water outlets 101 in the flow direction of the water flow, and when the driver 12 drives the pulsator body 11 to rotate, the water in each flow channel flows from the water outlets 101 to the water passing cavity, and is finally ejected from the plurality of water outlets 101 under the action of the water pressure, so that a plurality of strong impact water flows are formed.
According to another alternative embodiment of the present invention, the water outlets 101 include a plurality of water outlets 101, and the plurality of water outlets 101 are communicated with the outlets of the plurality of flow channels in a one-to-one correspondence. That is, when the driver 12 drives the pulsator body 11 to rotate, water in each flow channel flows out from the corresponding water outlet 101, thereby forming a plurality of strong impact water streams.
In some examples, the plurality of water outlets 101 are arranged at intervals along the circumferential direction, and the plurality of water-stirring ribs 13 are located outside the circumference enclosed by the plurality of water outlets 101.
Specifically, the driver 12 drives the pulsator body 11 to rotate, the plurality of water stirring ribs 13 located on the upper surface of the pulsator body 11 can stir water around the pulsator body to rotate, so that water flow is formed on the outer ring of the pulsator body 11, and when the pulsator body 11 rotates, the water located in the flow channel can spirally flow along the extending direction of the flow channel and is finally sprayed out from the plurality of water outlets 101, so that water flow is formed in the middle of the pulsator body 11, and thus, the two parts of water flow can strongly impact the clothes, and the washing ratio of the clothes is improved.

That is, the inlet opening angle α of the flow channel is 5 ° to 25 °, for example, the inlet opening angle of the flow channel may be 16 °. By limiting the inlet opening angle of the flow channel within the above range, the flow rate and the strength of the water flow can be both considered, thereby improving the washing ratio of the clothes.
According to one embodiment of the invention, the included angle between the tangent lines of the two contour lines formed by the orthographic projection of the flow channel on the horizontal plane at the outlet of the flow channel is beta, wherein beta is more than or equal to 1 degree and less than or equal to 5 degrees. In other words, the outlet angle of the flow channel is 1 ° to 5 °, for example, the outlet angle β of the flow channel may be 3 °. By limiting the outlet angle of the flow passage within the above range, the flow rate and the strength of the water flow can be simultaneously achieved, thereby improving the washing ratio of the clothes.
According to one embodiment of the invention, the width of the flow channel is gradually decreasing in the flow direction of the water flow. Through setting the runner to its width dimension along the flow direction of rivers and reducing gradually, can increase water pressure along with the runner of rivers to improve the velocity of water in the exit of runner, thereby improve the impact strength of rivers, be favorable to promoting the washing of clothing and compare.
The spiral lifting angle of the flow channel in the application is gradually changed along with the increase of the height, in order to further improve the impact strength of the water flow, the included angle between the tangent line of the contour line formed by the orthographic projection of the flow channel on the horizontal plane at the inlet of the flow channel and the tangent line at the outlet of the flow channel is gamma, the angle is more than or equal to 90 degrees and less than or equal to 120 degrees, and the angle is 107 degrees for example.

When the driver 12 drives the pulsator body 11 to rotate counterclockwise (a direction shown in fig. 4), the plurality of water stirring ribs 13 drive water around the pulsator body 11 to rotate counterclockwise, so that water flow rotating counterclockwise is formed, and when the pulsator body 11 rotates, a part of water enters the first flow channel 102 from the inlet of the first flow channel 102 and gradually and spirally flows upwards along the extending direction of the first flow channel 102, so that water flow rotating clockwise is formed and finally is ejected from the plurality of water outlets 101, and in the process, no water exists in the second flow channel 103.
When the driver 12 drives the pulsator body 11 to rotate clockwise (in the direction shown by b in fig. 5), the plurality of water stirring ribs 13 drive water around the pulsator body 11 to rotate clockwise, so that a clockwise rotating water flow is formed, and when the pulsator body 11 rotates, a part of water enters the second flow channel 103 from the inlet of the second flow channel 103 and gradually and spirally flows upwards along the extending direction of the second flow channel 103, so that a counterclockwise rotating water flow is formed and finally is ejected from the plurality of water outlets 101, and in the process, no water exists in the first flow channel 102.
Therefore, no matter the driver 12 drives the pulsator body 11 to rotate clockwise or drives the pulsator body 11 to rotate anticlockwise, the water flows are sprayed out of the water outlets 101, so that two strong impact water flows in opposite directions are formed around the pulsator body 11, and the washing ratio of clothes is improved.
In some examples, the first flow channel 102 and the second flow channel 103 respectively include a plurality, and the plurality of first flow channels 102 are located above the plurality of second flow channels 103 and spaced apart from each other.
