It will be apparent that the described embodiments are only some, but not all, embodiments of the application. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments of the present application.

Reference herein to "an embodiment" or "implementation" means that a particular feature, component, or characteristic described in connection with the embodiment or implementation may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The embodiment of the application provides a pulsator assembly and a washing machine, which are used for solving the problem that the washing effect of the existing washing machine is not ideal. This will be described below with reference to the accompanying drawings.

The pulsator assembly 10 provided by the embodiment of the application is suitable for a pulsator washing machine, wherein the pulsator washing machine can be a single-tub washing machine or a double-tub washing machine. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a portion of a pulsator washing machine according to an embodiment of the present application. The pulsator washing machine 100 may include a driving motor (not shown in the drawings), a tub 20, and a pulsator assembly 10, wherein the pulsator assembly 10 can rotate with respect to the tub 20 to turn laundry, thereby implementing a washing function. When the clothes are washed, the driving motor can drive the impeller assembly 10 to rotate in the forward and reverse directions to drive the clothes to turn over continuously up and down and left and right, so that soft friction is carried out among the clothes, between the clothes and the barrel wall in water, and decontamination cleaning is realized under the action of a detergent.

For a clearer description of the structure of the pulsator assembly 10, the pulsator assembly 10 will be described with reference to the accompanying drawings.

For example, referring to fig. 2, fig. 2 is a schematic structural diagram of a pulsator assembly according to an embodiment of the present application. The pulsator assembly 10 includes a pulsator 11 and a pulsator convex hull 12, the pulsator convex hull 12 is disposed on the pulsator 11, and the pulsator convex hull 12 is disposed on an upper surface of the pulsator 11, which is illustrated by taking a case that the pulsator assembly 10 is normally installed in the washing tub 20, as it can be understood that the pulsator convex hull 12 protrudes upward with respect to the pulsator 11. When the driving motor drives the pulsator 11 to rotate, the stirring convex hull 12 is disposed on the upper surface of the pulsator 11, so that the stirring convex hull 12 also rotates together. Because the stirring convex hull 12 protrudes upwards relative to the pulsator 11, the stirring convex hull 12 can play a role in stirring water flow and turning clothes in the rotating process of the pulsator 11, and the washing effect is improved.

In the conventional pulsator washing machine, dirt such as cotton and velvet falls off from clothes in the washing process, and water eddies generated by the pulsator cannot stir the clothes well, so that the washing effect of the washing machine is not ideal.

Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram illustrating another view of the pulsator assembly in fig. 2;

Fig. 5 is an exploded view of a pulsator assembly according to an embodiment of the present application. In order to fully agitate water flow, the impeller assembly 10 provided in the embodiment of the present application further provides an insert plate 13, wherein the insert plate 13 includes a water-shifting portion 132, and the water-shifting portion 132 and the agitating convex hull 12 provided in the embodiment of the present application are respectively located at two opposite sides of the impeller 11. It will be appreciated that, taking the example that the pulsator assembly 10 is normally installed in the washing tub 20 as an example, the water-stirring portion 132 and the stirring convex hull 12 are respectively located at two opposite sides of the pulsator 11, it will be understood that the stirring convex hull 12 is located at an upper side of the pulsator 11, and the water-stirring portion 132 is located at a lower side of the pulsator 11.

The stirring convex hull 12 is provided with a structure with a containing cavity 121, a water inlet 122 communicated with the containing cavity 121 is formed in the stirring convex hull 12, namely, a water inlet 122 communicated with the containing cavity 121 is formed in the side wall of the stirring convex hull 12, so that thread scraps can flow into the containing cavity 121 from the water inlet 122, and in order to collect the thread scraps in the containing cavity 121, the inserting plate 13 further comprises a thread scraps attaching part 131, the thread scraps attaching part 131 is arranged in the containing cavity 121, and the water poking part 132 penetrates out of the containing cavity 121, namely, the water poking part 132 is at least partially positioned outside the containing cavity 121. The thread scraps can be attached to the thread scraps attaching part 131 so as to prevent the thread scraps from flowing out of the accommodating cavity 121, and the water-shifting part 132 penetrating out of the accommodating cavity 121 can shift water flow when the impeller 11 rotates, and the stirring effect of the stirring convex hull 12 is added, so that the washing effect can be effectively improved. It will be appreciated that the insert 13 integrates the functions of adsorbing lint and agitating the water stream, and can enhance the washing effect while simplifying the structure of the pulsator assembly. Also, in comparison with the related art in which the filter is provided at the sidewall of the washing tub 20, the embodiment of the present application provides the lint attaching part 131 for adsorbing lint at the pulsator 11, i.e., at the bottom of the washing machine, to facilitate the collection of lint.

Of course, in other embodiments, the water-pulling portion 132 may not be perpendicular to the pulsator 11, and may be inclined at a certain angle.

In other embodiments, the plugboard 13 is detachably inserted on the stirring convex hull 12, and the plugboard 13 can be replaced according to actual situations, for example, when a related performance test, such as a washing machine washing ratio test, a clothes overturning effect test or a cloth circulation test, is performed, a plurality of impellers 11 with different specifications are not required to be manufactured, a plurality of plugboards 13 with different specifications are only required to be manufactured (the sizes of the water-shifting parts 132 on the different plugboards 13 can be set to be different), and the plugboard 13 can be replaced according to needs, so that the cost is saved, and convenience and rapidness are realized. And the plugboard 13 is made into a detachable structure, so that the plugboard 13 which is full of thread scraps can be replaced conveniently.
