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.

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. By arranging the first flow channels 102 and the second flow channels 103 at intervals in the vertical direction, a plurality of first flow channels 102 or a plurality of second flow channels 103 can be arranged on the same design surface, so that a certain number of flow channels are arranged, a certain amount of water flow is sprayed out when the pulsator body 11 rotates forward and backward, and the washing ratio of clothes is further improved.

In some examples, the first flow channel 102 and the second flow channel 103 respectively include a plurality of first flow channels 102 and second flow channels 103, which are arranged in a staggered manner on an orthogonal projection of the same horizontal plane.

Through dialling a plurality of muscle 13 and arranging along the circumferencial direction interval, a plurality of muscle 13 of dialling can stir the rotatory or reverse rotation of water forward around the impeller body 11 together to promote the intensity of rivers, form the impact rivers that more strengthen powerfully, and then promote the washing of clothing and compare.

In some examples, the middle part of impeller body 11 has the cylinder that upwards extends, and a plurality of delivery ports 101 are established on the cylinder and along the circumference interval arrangement of cylinder, and a plurality of muscle of dialling 13 are located the cylinder all around and along the circumference interval arrangement of cylinder, and wherein, a part in a plurality of muscle of dialling is first muscle of dialling, and the rest is the second muscle of dialling, and first muscle of dialling and the second muscle of dialling all extend along the radial of rim plate, and the length of first muscle of dialling is less than the length of second muscle of dialling.

In some specific examples, the plurality of first water-repellent ribs and the plurality of second water-repellent ribs are staggered and spaced along a circumferential direction of the wheel disc.

The laundry treating apparatus 200 according to an embodiment of the present invention includes the pulsator assembly 100 according to the above-described embodiment. Since the pulsator assembly 100 according to the embodiment of the present invention has the above technical effects, the laundry treating apparatus 200 according to the embodiment of the present invention also has the above technical effects, that is, the laundry treating apparatus 200 of the present application has a simple structure and a high washing ratio of laundry.

As shown in fig. 1, in some examples, the laundry treating apparatus 200 is a washing machine and includes a cabinet 21, an outer tub 22, and an inner tub 23, the cabinet 21 extending in an up-down direction and having a receiving cavity with an open top and a cover for opening and closing a top opening of the receiving cavity, the outer tub 22 provided in the cabinet 21 and extending in the up-down direction, the inner tub 23 rotatably provided in the outer tub 22, and the pulsator assembly 100 provided at a bottom of the inner tub 23 and rotatable with respect to the inner tub 23.

In some specific examples, the inner tube 23 has a plurality of water holes spaced apart from each other on the wall thereof, so as to communicate the inner tube 23 with the outer tube 22, so that water can freely pass through the water holes.

Other constructions and operations of the laundry treating apparatus 200 (e.g., a washing machine or a laundry dryer) according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples" or the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
