Description

Technical Field

[0001] The present application relates to the technical field of electrical appliance manufacturing, and in particular to a pulsator assembly and a clothing processing device. Background Art

[0002] Currently, there are two types of fully automatic washing machines on the market: pulsator type and agitator type. The pulsator type uses the high-speed rotation of the pulsator to create a strong vortex that drives the clothes to tumble in the barrel, while the agitator type uses a stirring rod to slowly rub the clothes in three dimensions.

[0003] Although pulsator washing has a faster washing speed, it can easily cause accelerated aging of clothing fibers due to friction and entanglement, especially significant damage to high-end fabrics (such as silk and lace). Large pieces of clothing (such as quilt covers) can easily clump together in the vortex, making it difficult to thoroughly clean the inner layer. At the same time, pulsator washing requires a high water level to maintain water flow intensity, resulting in serious waste of water resources. The agitator washing method is gentler and can reduce damage to clothing, but the single washing cycle is longer, the energy consumption is higher, and the stirring rod occupies the central space of the inner barrel, which limits the single washing capacity. Users are forced to choose between pulsator washing machines and agitator washing machines, which cannot meet diversified needs. Summary of the Invention

Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0038] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0041] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0042] See also Figures 1 to 5An embodiment of the present application provides a pulsator assembly 100, including a pulsator 20 and a first stirring rod 30, wherein the first stirring rod 30 is slidingly connected to the pulsator 20, and the pulsator 20 has a first embedded space 25, and the first stirring rod 30 can slide in and out of the first embedded space 25, and is fixedly connected to the pulsator 20 at one or more nodes during the sliding process.

[0043] The pulsator assembly 100 provided in the embodiment of the present application can be applied to a washing machine. The pulsator assembly 100 includes a first stirring rod 30 and a pulsator 20 that are slidably connected. When the first stirring rod 30 slides into the first embedded space 25, the pulsator assembly 100 takes on the appearance of the pulsator 20. At this time, the washing machine exhibits the function of pulsator washing. When the first stirring rod 30 slides out of the first embedded space 25 and is fixedly connected to the pulsator 20, at this time, at least a portion of the first stirring rod 30 is located above the pulsator 20, so that the washing machine exhibits the function of stirring washing, so that the two washing modes can be switched using one washing machine, thereby meeting the diversified needs of users.

[0044] In the embodiments of the present application, a plurality refers to two or more, for example, three, four, five, six, seven, eight, etc.

[0045] It can be understood that when the first stirring rod 30 can be fixedly connected to the impeller 20 at one or more nodes during the sliding process, it can be fixedly connected to the impeller 20 by selecting different node positions, and the height of the part of the first stirring rod 30 exposed above the impeller 20 can be adjusted, thereby realizing the adjustment of the stirring rod height of the impeller assembly 100.

[0046] It should be noted that the characteristics of pulsator washing are: when the pulsator 20 rotates, it mainly generates "vortex water flow", that is, the clothes rotate with the pulsator 20 to form a circulating water flow with the center downward and the edge upward. It is more efficient when washing small pieces of clothing, but large pieces of clothing are prone to entanglement and knotting. At the same time, since pulsator washing requires a high water level to maintain water flow intensity, water resources are wasted more seriously.

[0047] It should be noted that the characteristics of agitator washing are: the impeller 20 rotates to form a vortex water flow, and the raised structure (fan blades) on the stirring rod cuts the water flow, generating up and down turbulence (similar to the rubbing action when rubbing with hands), making the clothes in the barrel show a three-dimensional motion of "up and down rolling + left and right friction", which can reduce entanglement and improve rolling uniformity. It can be seen that the agitator washing method is relatively gentle and can reduce damage to clothes, but the single washing cycle is longer and the energy consumption is higher. In addition, the stirring rod occupies the central space of the inner barrel, which limits the single washing capacity.

[0048] This application uses an innovative deformable structure to achieve hardware-level switching between two washing modes (pulsator washing and agitator washing) for the first time, which not only fills the market gap, but also provides a new technical path for the intelligence and greening of home appliances.

[0049] See also Figure 5 The impeller 20 includes a wheel disc 21, a first cylinder 22 and a plurality of first ribs 23. The wheel disc 21 is arranged on the periphery of the first cylinder 22 and is connected to the first cylinder 22. At least a portion of the first cylinder 22 protrudes from the upper surface of the wheel disc 21; a plurality of first ribs 23 are distributed on the periphery of the first cylinder 22 and are connected to the first cylinder 22. The internal spaces of the plurality of first ribs 23 are all connected to the internal space of the first cylinder 22. The first embedded space 25 includes the internal spaces of the plurality of first ribs 23 and the internal space of the first cylinder 22.

[0050] It should be noted that in the embodiments of the present application, the upper and lower positional relationships refer to the positional relationship of the impeller assembly when in use.

[0051] Exemplarily, the impeller 20 is prepared by one-piece molding (such as injection molding), that is, the wheel disc 21, the first cylinder 22 and the plurality of first ribs 23 are an integrated structure.

[0052] See also Figure 6 The first stirring rod 30 includes a first rod body 31 and a plurality of first blades 32. The plurality of first blades 32 are distributed on the periphery of the first rod body 31 and connected to the first rod body 31; see Figure 5 When the first stirring rod 30 enters the first embedded space 25 , the first blades 32 respectively enter the inner spaces of the first ribs 23 , and the first rod body 31 enters the inner space of the first cylinder 22 .

[0053] It can be understood that the first rib 23 can not only serve to accommodate the first blade 32 of the first stirring rod 30, but also the first rib 23 itself can serve as a fan blade. When the impeller assembly 100 rotates, the first rib 23 can cut the water flow, causing turbulent flow in the barrel, similar to the rubbing action when rubbing with hands, thereby improving the washing effect of clothes.

[0054] See also Figure 5The inner wall of the first cylinder 22 is provided with a plurality of first engaging grooves 221, the first engaging grooves 221 including a first groove portion 201 and a second groove portion 202, the first groove portion 201 and the second groove portion 202 being arranged in sequence in the first direction and being connected, the lower end of the first groove portion 201 is lower than the lower end of the second groove portion 202 in the second direction, and the second groove portion 202 is connected to the inner space of the first rib 23; see Figure 6 The first stirring rod 30 also includes a plurality of first protrusions 312, which are distributed on the periphery of the first rod body 31 and connected to the first rod body 31, and the first protrusions 312 are arranged below the first fan blade 32; the first protrusions 312 can pass through the second groove portion 202 from the internal space of the first rib 23 into the first groove portion 201 to achieve a fixed connection between the first stirring rod 30 and the impeller 20, and can pass through the second groove portion 202 from the first groove portion 201 into the internal space of the first rib 23 to achieve separation of the first stirring rod 30 from the impeller 20.

[0055] Exemplarily, the first direction and the second direction are perpendicular to each other.

[0056] Illustratively, in the first stirring rod 30 , the plurality of first protrusions 312 are respectively provided corresponding to the plurality of first blades 32 .

[0057] It can be understood that when the first stirring rod 30 is stretched out from the impeller 20 and the first stirring rod 30 is fixedly connected to the impeller 20, the first protrusion 312 of the first stirring rod 30 can be first lifted to the same level as the second groove portion 202, and then the first stirring rod 30 can be slightly rotated so that the first protrusion 312 first enters the second groove portion 202 and then enters the first groove portion 201. Since the position of the first groove portion 201 is lower, the first protrusion 312 is stuck in the first groove portion 201 and cannot rotate or move downward, thereby achieving fixed installation of the first stirring rod 30 and the impeller 20.

[0058] When the first stirring rod 30 needs to be hidden in the impeller 20, the first protrusion 312 of the first stirring rod 30 can be first lifted upward to the same level as the second groove 202, and then the first stirring rod 30 can be slightly rotated so that the first protrusion 312 first enters the second groove 202 and then enters the internal space of the first rib 23. At this time, the first stirring rod 30 can move downward, thereby realizing the nesting of the first stirring rod 30 and the impeller 20.

[0059] See also Figure 5For example, the first engaging groove 221 is arranged near the top end of the first cylinder 22 , and the first protrusion 312 is arranged near the bottom end of the first rod 31 .

[0060] See also Figure 5 For example, the upper end of the first groove portion 201 is flush with the upper end of the second groove portion 202 , and at this time, the first engaging groove 221 is L-shaped.

[0061] See also Figure 7 The impeller assembly 100 also includes a second stirring rod 40, which is slidingly connected to the first stirring rod 30; the first stirring rod 30 has a second embedded space 33, and the second stirring rod 40 can slide in and out of the second embedded space 33, and one or more nodes during the sliding process are fixedly connected to the first stirring rod 30.

[0062] See also Figure 6 The first rod body 31 and the multiple first blades 32 all have a hollow structure, the hollow structures of the multiple first blades 32 are all connected to the hollow structure of the first rod body 31, and the second embedded space 33 includes the hollow structures of the multiple first blades 32 and the hollow structure of the first rod body 31.

[0063] See also Figure 7 The second stirring rod 40 includes a second rod body 41 and a plurality of second blades 42. The plurality of second blades 42 are distributed on the periphery of the second rod body 41 and connected to the second rod body 41; see Figure 6 When the second stirring rod 40 enters the second embedded space 33 , the plurality of second blades 42 respectively enter the hollow structures of the plurality of first blades 32 , and the second rod body 41 enters the hollow structure of the first rod body 31 .

[0064] It can be understood that the first fan blade 32 has a dual function. First, the first fan blade 32 serves as a raised structure on the outer periphery of the first stirring rod 30, which can cut the water flow, so that turbulent flow is generated in the barrel, and the clothes are made to perform a three-dimensional movement of "up and down rolling + left and right friction" in the barrel, thereby improving the washing effect of the clothes. Secondly, since the first fan blade 32 has a hollow structure inside, when it is necessary to lower the height of the stirring rod of the impeller assembly 100, the second fan blade 42 of the second stirring rod 40 can also be embedded in the first fan blade 32 to achieve the nesting of the first stirring rod 30 and the second stirring rod 40.

[0065] See also Figure 6The inner wall of the first rod 31 is provided with a plurality of second engaging grooves 311, and the second engaging grooves 311 include a third groove portion 301 and a fourth groove portion 302. The third groove portion 301 and the fourth groove portion 302 are sequentially arranged and connected in the first direction. In the second direction, the lower end of the third groove portion 301 is lower than the lower end of the fourth groove portion 302, and the fourth groove portion 302 is connected to the hollow structure of the first fan blade 32; please refer to Figure 7 The second stirring rod 40 also includes a plurality of second protrusions 411, which are distributed on the outer periphery of the second rod body 41 and connected to the second rod body 41, and the second protrusions 411 are arranged below the second fan blade 42; the second protrusions 411 can pass through the fourth groove portion 302 from the hollow structure of the first fan blade 32 into the third groove portion 301 to achieve a fixed connection between the second stirring rod 40 and the first stirring rod 30, and can pass through the fourth groove portion 302 from the third groove portion 301 into the hollow structure of the first fan blade 32 to achieve separation of the second stirring rod 40 from the first stirring rod 30.

[0066] Exemplarily, the first direction and the second direction are perpendicular to each other.

[0067] Illustratively, in the second stirring rod 40 , the plurality of second protrusions 411 are respectively provided corresponding to the plurality of second blades 42 .

[0068] It can be understood that when the second stirring rod 40 needs to be stretched out from the first stirring rod 30 and the second stirring rod 40 and the first stirring rod 30 need to be fixedly connected, the second protrusion 411 of the second stirring rod 40 can be first lifted to the same level as the fourth groove 302, and then the second stirring rod 40 can be slightly rotated so that the second protrusion 411 first enters the fourth groove 302 and then enters the third groove 301. Since the position of the third groove 301 is lower, the second protrusion 411 is stuck in the third groove 301 and cannot rotate or move downward, thereby achieving fixed installation of the second stirring rod 40 and the first stirring rod 30.

[0069] When the second stirring rod 40 needs to be hidden in the first stirring rod 30, the second protrusion 411 of the second stirring rod 40 can be first lifted upward to the same level as the fourth groove 302, and then the second stirring rod 40 can be slightly rotated so that the second protrusion 411 first enters the fourth groove 302 and then enters the internal space of the first fan blade 32. At this time, the second stirring rod 40 can move downward, thereby realizing the nesting of the second stirring rod 40 and the first stirring rod 30.

[0070] See also Figure 6For example, the second engaging groove 311 is arranged close to the top end of the first rod 31 , and the second protrusion 411 is arranged close to the bottom end of the second rod 41 .

[0071] See also Figure 6 For example, the upper end of the third groove portion 301 is flush with the upper end of the fourth groove portion 302 , and at this time, the second engaging groove 311 is L-shaped.

[0072] See also Figure 1 and Figure 5 For example, the heights of the first stirring rod 30 and the second stirring rod 40 may be equal, and the height of the first embedding space 25 may be slightly greater than, equal to, or slightly less than the height of the first stirring rod 30 .

[0073] It should be noted that when the impeller assembly 100 includes both the first stirring rod 30 and the second stirring rod 40, the impeller assembly 100 can switch between three states:

[0074] See also Figure 8 、 Figure 9 and Figure 10 The first form is the pulsator form. At this time, the second stirring rod 40 enters the second embedded space 33 of the first stirring rod 30, and the first stirring rod 30 enters the first embedded space 25 of the pulsator 20. That is to say, the first stirring rod 30 and the second stirring rod 40 are both located in the first embedded space 25. The pulsator assembly 100 appears to be in the form of the pulsator 20. At this time, the washing machine including the pulsator assembly 100 has the function of pulsator washing.

[0075] The second form is a stirring rod form. At this time, the second stirring rod 40 enters the second embedded space 33 of the first stirring rod 30, but the first stirring rod 30 protrudes from the impeller 20 and is fixedly connected to the impeller 20, or, the first stirring rod 30 enters the first embedded space 25 of the impeller 20, but the second stirring rod 40 protrudes from the first stirring rod 30 and is fixedly connected to the first stirring rod 30, that is, the structure protruding above the impeller 20 is the first stirring rod 30 or the second stirring rod 40. At this time, the washing machine including the impeller assembly 100 has the function of stirring washing, but the height of the stirring rod is relatively low.

[0076] See also Figure 1 、 Figure 2 and Figure 3The third form is also a stirring rod form. At this time, the second stirring rod 40 protrudes from the first stirring rod 30 and is fixedly connected to the first stirring rod 30. The first stirring rod 30 protrudes from the pulsator 20 and is fixedly connected to the pulsator 20. That is to say, the structure protruding above the pulsator 20 is a structure in which the first stirring rod 30 and the second stirring rod 40 are arranged in sequence in the vertical direction. At this time, the washing machine including the pulsator assembly 100 has the function of stirring washing, and the height of the stirring rod is relatively high.

[0077] It can be understood that although the second form and the third form are both stirring rod forms, due to the different heights of the stirring rods, the water flow characteristics generated during the washing process are also different, thereby forming different washing effects.

[0078] See also Figure 1 In the third form (stirring rod form), the first rib 23 on the impeller 20, the first blade 32 on the first stirring rod 30, and the second blade 42 on the second stirring rod 40 are staggered with each other. Therefore, during the washing process, the first rib 23, the first blade 32, and the second blade 42 can cut the water flow from different positions respectively, thereby achieving more complex water flow characteristics and enhancing the washing effect of clothes.

[0079] It should be noted that, in some other embodiments, the impeller assembly 100 may further include a third stirring rod, which is slidably connected to the second stirring rod 40. The second stirring rod 40 has a third embedded space. The third stirring rod can slide in and out of the third embedded space, and one or more nodes during the sliding process are fixedly connected to the second stirring rod 40. In this embodiment, the heights of the first stirring rod 30, the second stirring rod 40, and the third stirring rod can be equal, and the height of the first embedded space 25 is slightly greater than, equal to, or slightly less than the height of the first stirring rod 30.

[0080] It can be understood that the impeller assembly 100 can include multiple (for example, three or more) stirring rods, and the multiple stirring rods can be nested with each other, and the final structure formed is the height of one stirring rod. The multiple stirring rods can be unfolded and connected and fixed in sequence, and the final structure formed is the sum of the heights of the multiple stirring rods. By controlling the height of a single stirring rod and the number of stirring rods in the impeller assembly 100, the overall height of the stirring rod assembly of the impeller assembly 100 can be controlled.

[0081] See also Figure 5The impeller 20 also includes a plurality of blades 26, which are distributed on the outer periphery of the first cylinder 22. The outer surface of the first cylinder 22 and the upper surface of the wheel disc 21 are connected to the blades 26, and the plurality of blades 26 are staggered with the plurality of first ribs 23.

[0082] It can be understood that the blades 26 on the pulsator 20 can push the water flow to form different forms such as vortex or scrubbing during the rotation process, which can not only improve the efficiency of stain removal through mechanical flushing and friction, but also drive the clothes to roll evenly to prevent the clothes from being entangled.

[0083] Exemplarily, the impeller assembly 100 further includes a driving device, a driving shaft of which is connected to the impeller 20 to drive the impeller 20 to rotate.
