Description

Technical Field

[0001] This application relates to the field of electrical manufacturing technology, and in particular to a pulsator assembly and clothing processing equipment. Background Technology

[0002] In the laundry equipment industry, top-loading washing machines have become a common choice for both home and commercial settings due to their simple structure, low cost, and high washing efficiency. Traditional top-loading washing machines use a rotating impeller at the bottom to create a vortex of water flow, which causes the clothes to rub against the detergent to remove dirt. However, this method has obvious drawbacks. Because the impeller rotates continuously in one direction, the clothes tend to move in concentric circles with the water flow, causing the collars, trouser legs, and other parts to get tangled together. This tangling problem is particularly prominent when washing mixed materials or large items, resulting in incomplete washing and accelerated wear and tear on the clothes.

[0003] To alleviate the problem of clothes tangling, an anti-tangling rod is usually added to the impeller at the bottom of the washing machine drum. The anti-tangling rod can intervene in the water flow pattern through physical structure to reduce clothes tangling and improve the washing effect. However, during the operation of the washing machine, the anti-tangling rod is prone to swaying from side to side, which weakens the anti-tangling effect and makes it easy for the anti-tangling rod to fall off the impeller.

[0012] The impeller also includes a third connecting part, which is connected to one end of the third cylinder near the wheel, and the third connecting part is provided with a second through hole;

[0013] The drive shaft is provided with a threaded hole, and the impeller assembly also includes a screw, which passes through the first through hole and the second through hole into the threaded hole and is threadedly connected to the hole wall of the threaded hole.

[0014] In some embodiments, the third connecting portion is further provided with a third through hole, the second through hole and the third through hole are arranged sequentially in the direction from the protrusion to the wheel and are interconnected with each other, the cross-sectional area of ​​the third through hole is larger than the cross-sectional area of ​​the second through hole, and a portion of the drive shaft enters the third through hole.

[0015] In some embodiments, the impeller further includes a plurality of reinforcing ribs, one side of which is connected to the inner wall surface of the fourth cylinder, and the other side is connected to the outer surface of the third cylinder and the outer surface of the third connecting portion.

[0016] In some embodiments, the anti-winding rod further includes a plurality of first ribs, all of which are disposed on the outside of the first cylinder and connected to the first cylinder.

[0039] Please see Figures 1 to 5 This application provides a pulsator assembly 100, including a pulsator 20 and an anti-winding rod 30. The pulsator 20 includes a wheel 21 and a protrusion 22. The protrusion 22 is disposed on one side of the wheel 21 and connected to the wheel 21. The protrusion 22 has an inner cavity and a first top surface 221 disposed around the inner cavity.

[0040] The anti-winding rod 30 includes a first cylinder 31, a second cylinder 32, and a first connecting part 33. The cross-sectional area enclosed by the outer periphery of the second cylinder 32 is smaller than the cross-sectional area enclosed by the outer periphery of the first cylinder 31. The first connecting part 33 is disposed on the inner side of the bottom end of the first cylinder 31 and surrounds the top end of the second cylinder 32. Both the first cylinder 31 and the second cylinder 32 are connected to the first connecting part 33.

[0041] At least a portion of the second cylindrical body 32 enters the inner cavity of the protrusion 22, and the first top surface 221 of the protrusion 22 abuts against the bottom surface of the first connecting portion 33.

[0042] For example, the protrusion 22 is located at the center of the wheel 21.

[0043] The impeller assembly 100 provided in this application embodiment has a second cylindrical body 32 of the anti-winding rod 30 entering the inner cavity of the protrusion 22 of the impeller 20. At the same time, the first top surface 221 of the protrusion 22 of the impeller 20 abuts against the bottom surface of the first connecting part 33 of the anti-winding rod 30. The above-mentioned structure not only plays a guiding role in the installation process of the anti-winding rod 30 and the impeller 20, but also, since the second cylindrical body 32 enters the inner cavity of the protrusion 22, the protrusion 22 can restrict the horizontal movement of the anti-winding rod 30, thereby avoiding the phenomenon of left and right swaying of the anti-winding rod 30 during operation, and at the same time enhancing the connection stability between the anti-winding rod 30 and the impeller 20.

[0044] Please see Figure 8 , Figure 9 and Figure 10 The inner surface of the protrusion 22 is provided with a plurality of protrusion structures 202, please refer to [link / reference]. Figure 6 and Figure 7 The outer surface of the second cylinder 32 is provided with a plurality of recesses 321, and the plurality of recesses 321 all penetrate the bottom end of the anti-winding rod 30. Please refer to [link / reference]. Figure 5 The multiple protrusions 202 respectively enter the multiple recesses 321, and the top surfaces of the multiple protrusions 202 respectively abut against the inner wall surfaces of the multiple recesses 321.

[0045] It is understandable that by providing a protruding structure 202 on the inner surface of the protrusion 22 and a recessed portion 321 on the outer surface of the second cylinder 32, and by having the protruding structure 202 enter multiple recessed portions 321 respectively, on the one hand, the mutual cooperation between the protruding structure 202 and the recessed portion 321 can play a guiding role in the installation process of the anti-winding rod 30 and the impeller 20; on the other hand, since the protruding structure 202 is inserted into the recessed portion 321, the movement and rotation of the anti-winding rod 30 in the horizontal direction can be further restricted, thereby further enhancing the connection stability between the anti-winding rod 30 and the impeller 20 and preventing the anti-winding rod 30 from swaying or rotating left and right during operation.

[0046] It should be noted that the core function of the anti-tangling rod 30 relies on its fixed position to stably interfere with the water flow. When the anti-tangling rod 30 sways from side to side, the relative position of the first rib 35 on the surface of the anti-tangling rod 30 and the water flow will change randomly, resulting in unstable turbulence generation, failure of water flow guidance, and inability to effectively break the conditions for clothing tangling.

[0047] This application solves the problem of the anti-winding rod 30 swaying left and right during operation by setting the second cylinder 32 of the anti-winding rod 30 into the inner cavity of the protrusion 22 of the impeller 20, and designing the protrusion structure 202 on the inner surface of the protrusion 22 to cooperate with the recess 321 on the outer surface of the second cylinder 32. It also enhances the connection stability between the anti-winding rod 30 and the impeller 20.

[0048] For example, a plurality of the protruding structures 202 are arranged sequentially at intervals around the inner periphery of the third cylinder 223.

[0049] In the embodiments of this application, "multiple" refers to two or more, such as three, four, five, six, seven, eight, nine, ten, etc.

[0050] In some embodiments, the inner surface of the protrusion 22 is provided with two protrusion structures 202, which are symmetrically arranged, and the outer surface of the second cylinder 32 is provided with two recesses 321, which are symmetrically arranged.

[0051] Please see Figure 2 and Figure 5 The impeller assembly 100 further includes a drive device 40, which includes a connected device body 41 and a drive shaft 42. The drive shaft 42 is connected to the anti-winding rod 30 and the impeller 20 to drive the anti-winding rod 30 and the impeller 20 to rotate.

[0052] Understandably, by connecting the drive shaft 42 of the drive device 40 to the impeller 20, the impeller 20 can rotate to generate water flow and mechanical force, thereby achieving the washing, rubbing and cleaning of clothes.

[0053] It should be noted that the anti-tangling rod of a traditional pulsator washing machine is a fixed structure (e.g., the anti-tangling rod is directly welded to the bottom of the inner drum). It can meet the anti-tangling requirements through static physical barriers and water flow cutting. However, in this embodiment, the drive shaft 42 of the drive device 40 is connected to the anti-tangling rod 30, so that the anti-tangling rod 30 can rotate actively. During the rotation, the anti-tangling rod 30 can actively untangle tangled clothes (e.g., knotted sheets, bath towels, etc.). Compared with the fixed structure, the intervention is more direct, which is especially suitable for washing large or multiple items of clothing. Secondly, when the anti-tangling rod 30 and the pulsator 20 rotate synchronously, the water flow generated by the two will overlap to form a three-dimensional turbulent flow of "up and down tumbling + circular rotation", which makes the movement trajectory of the clothes in the drum more complex, the detergent penetration more even, and the stain removal efficiency further improved.

[0054] Please see Figure 9 and Figure 10The protrusion 22 includes a third cylindrical body 223 and a fourth cylindrical body 224 disposed around the third cylindrical body 223. The first top surface 221 is located between the top end of the third cylindrical body 223 and the top end of the fourth cylindrical body 224. Both the third cylindrical body 223 and the fourth cylindrical body 224 are connected to the first top surface 221. The inner cavity of the third cylindrical body 223 constitutes the inner cavity of the protrusion 22.

[0055] Please see Figure 7 The anti-winding rod 30 further includes a second connecting part 34, which is disposed in the inner cavity of the second cylinder 32 and connected to one end of the second cylinder 32 opposite to the first cylinder 31. The second connecting part 34 is provided with a first through hole 341.

[0056] Please see Figure 10 The impeller 20 also includes a third connecting part 50, which is connected to one end of the third cylinder 223 near the wheel 21. The third connecting part 50 is provided with a second through hole 51.

[0057] Please see Figure 5 The drive shaft 42 is provided with a threaded hole 421. The impeller assembly 100 also includes a screw 71, which passes through the first through hole 341 and the second through hole 51, enters the threaded hole 421, and is threadedly connected to the hole wall of the threaded hole 421.

[0058] It is understandable that by providing a first through hole 341 on the second connecting part 34, a second through hole 51 on the third connecting part 50, and a threaded hole 421 on the top of the drive shaft 42, the anti-winding rod 30, the impeller 20 and the drive device 40 can be connected with a single screw 71. This connection structure is relatively simple and can be quickly disassembled and assembled.

[0059] Please see Figure 5 and Figure 10 The third connecting part 50 is also provided with a third through hole 52. The second through hole 51 and the third through hole 52 are arranged sequentially and communicate with each other in the direction from the protrusion 22 to the wheel 21. The cross-sectional area of ​​the third through hole 52 is larger than the cross-sectional area of ​​the second through hole 51. A part of the drive shaft 42 enters the third through hole 52.

[0060] It is understandable that by setting the cross-sectional area of ​​the third through hole 52 to be larger than that of the second through hole 51, and by allowing a portion of the drive shaft 42 to enter the third through hole 52, the connection stability between the drive shaft 42 and the third connecting part 50 can be enhanced after the drive shaft 42 is connected to the third connecting part 50, thereby enhancing the connection stability between the drive device 40 and the impeller 20.

[0061] Please see Figure 11 The impeller 20 also includes a plurality of reinforcing ribs 62, one side of which is connected to the inner wall of the fourth cylinder 224, and the other side is connected to the outer surface of the third cylinder 223 and the outer surface of the third connecting part 50.

[0062] It is understandable that by providing multiple reinforcing ribs 62 in the impeller 20, with one side of the reinforcing rib 62 connected to the inner wall of the fourth cylinder 224 and the other side connected to the outer surface of the third cylinder 223 and the outer surface of the third connecting part 50, the reinforcing ribs 62 can connect the third cylinder 223 and the fourth cylinder 224 in the protrusion 22, thereby improving the mechanical strength and structural stability of the protrusion 22. At the same time, the reinforcing ribs 62 can connect the protrusion 22 and the third connecting part 50, thereby improving the overall mechanical strength and structural stability of the impeller 20.

[0063] Please see Figure 11 For example, a plurality of the reinforcing ribs 62 are arranged sequentially at intervals around the outer periphery of the third cylinder 223.

[0064] Please see Figure 1 and Figure 2 The anti-winding rod 30 also includes a plurality of first protruding ribs 35, which are all disposed on the outside of the first cylinder 31 and connected to the first cylinder 31.

[0065] It should be noted that by setting the first rib 35 on the anti-tangling rod 30, when the first rib 35 rotates with the anti-tangling rod 30, the first rib 35 will cut the annular water flow generated by the impeller 20 like a blade, turning the regular vortex into an irregular turbulence. When the direction and speed of the water flow in the turbulence are constantly changing, it can prevent clothes from gathering and tangling in the same direction (such as being more easily scattered when caught in the turbulence, rather than rolled into a ball). In addition, the first rib 35 can also directly hook or push open the edges of tangled clothes (such as shirt collars and trouser hems). Especially when washing multiple pieces of clothing, mechanical barriers can prevent clothes from tangling together and enhance the anti-tangling effect.

[0066] For example, a plurality of the first protruding ribs 35 are arranged sequentially at intervals around the outer periphery of the first cylinder 31.

[0067] For example, the extension direction of the plurality of first protruding ribs 35 is consistent with the extension direction of the anti-winding rod 30.

[0068] Please see Figure 1 and Figure 2For example, the first rib 35 includes a first extension 351 and a second extension 352. The first extension 351 and the second extension 352 are arranged in a single sequence and connected in the direction from the first cylinder 31 to the second cylinder 32. The width of the first extension 351 is smaller than the width of the second extension 352.

[0069] It should be noted that by setting the width of the first extension 351 on the first rib 35 to be smaller than the width of the second extension 352, the first extension 351 can be used to prevent light clothes from getting tangled, and the second extension 352 can be used to prevent heavy clothes from getting tangled. The narrower first extension 351 at the top has a weaker stirring effect, which can generate small water waves and push the light clothes to swing in a pendulum-like motion near the water surface, preventing the light clothes from gathering on the edge of the bucket wall and forming clumps due to excessive buoyancy. The wider second extension 352 at the bottom has a stronger stirring effect, which can quickly stir the water flow, causing the heavy clothes to repeatedly hit the bucket wall or the surface of the first rib 35 under the action of centrifugal force and impact force, and forcibly untangling them with mechanical force (the principle is similar to combing out knotted hair).

[0070] Please see Figure 1 and Figure 2 For example, the impeller 20 further includes a plurality of second ribs 61, all of which are disposed on the outer side of the protrusion 22 and connected to the protrusion 22.

[0071] For example, a plurality of second ribs 61 are arranged sequentially at intervals around the outer periphery of the protrusion 22.

[0072] For example, the extension direction of the plurality of second ribs 61 is consistent with the extension direction of the protrusion 22.

[0073] Please see Figure 1 and Figure 2 For example, the width of the second rib 61 is the same as the width of the second extension 352 of the first rib 35.

[0074] Please see Figure 1 and Figure 2 For example, a plurality of first ribs 35 and a plurality of second ribs 61 are respectively provided. When the anti-winding rod 30 is connected to the impeller 20, the bottom surface of the second extension 352 of the first rib 35 abuts against the top surface of the second rib 61.

[0075] Please see Figure 1 , Figure 2 and Figure 7 For example, the first cylindrical body 31 is provided with a plurality of hollowed-out portions 315.

[0076] It should be noted that by setting multiple hollow parts 315 on the first drum 31, the water flow on both sides of the anti-tangling rod 30 can produce a bidirectional penetration effect. When the anti-tangling rod 30 rotates, the water flow forms a cross flow through the hollow parts 315, breaking the inertia of the water flow in one direction, increasing the three-dimensional tumbling (up and down, left and right, rotation) of clothes in the washing drum, and reducing the tangling and knotting of clothes caused by one-way friction.

[0077] For example, the first connecting part 33 and the second connecting part 34 in the anti-winding rod 30 and the third connecting part 50 in the impeller 20 are all provided with through holes. These through holes allow the washing water that enters the anti-winding rod 30 from the hollow part 315 on the first cylinder 31 to flow downward and eventually return to the washing tub.

[0078] In some embodiments, a lint filter (not shown) may also be installed inside the first cylinder 31 and / or the second cylinder 32 of the anti-tangling rod 30. Lint, fibers and other impurities generated by clothing friction enter the anti-tangling rod 30 through the hollow part 315 on the first cylinder 31 with the water flow and are intercepted by the filter screen in the lint filter to prevent lint impurities from flowing back to the surface of the clothing.

[0079] Please see Figure 2 , Figure 3 and Figure 4 The impeller assembly 100 further includes a foreign object prevention cover 72, which is disposed at the end of the first cylinder 31 opposite to the second cylinder 32 and is detachably connected to the first cylinder 31. The foreign object prevention cover 72 is used to cover the opening at the end of the first cylinder 31 opposite to the second cylinder 32.

[0080] Understandably, the foreign object cover 72 can effectively prevent foreign objects from entering the interior of the anti-winding rod 30 from the top of the anti-winding rod 30, and prevent foreign objects from interfering with the normal operation of the anti-winding rod 30 or damaging the internal structure of the anti-winding rod 30.

[0081] For example, the foreign object protection cover 72 is connected to the first cylinder 31 by a snap-fit ​​connection.

[0082] This application also provides a garment processing device, including the impeller assembly 100 in any of the above embodiments.

[0083] For example, the garment handling equipment can be a top-loading washing machine or a top-loading washer-dryer combo.

[0084] The impeller assembly and garment processing equipment provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
