[0049] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0050] Reference below Figure 1-Figure 17 The impeller assembly 2 according to the first embodiment of the present invention is described.
[0051] like Figure 1 As shown, the pulsator assembly 2 according to the first embodiment of the present invention includes: a pulsator 21 and a clothes scrubbing element 22.
[0052] Specifically, the washing member 22 is disposed on the pulsator 21. In other words, the washing member 22 is movably disposed on the pulsator 21, and the washing member 22 is movable in the up-down direction relative to the pulsator 21. For example, a washing portion 221 may be formed on the surface of the washing member 22, and the washing portion 221 is suitable for washing clothes. Specifically, when the washing portion 221 and the clothes move relative to each other, the washing portion 221 can wash the clothes.
[0053] When the impeller 21 rotates, the impeller 21 can provide turning power and washing impact force for the clothes in the washing chamber. Since the clothes rubbing piece 22 is arranged on the impeller 21, and the clothes rubbing piece 22 can move up and down relative to the impeller 21, when the impeller 21 rotates, the clothes rubbing piece 22 can rotate together with the impeller 21, and the clothes rubbing piece 22 can also move in the up and down directions. Therefore, the clothes in the washing chamber can not only be rotated and washed by the rotation of the impeller 21, that is, the existence of the impeller 21 can realize horizontal washing, and the existence of the clothes rubbing piece 22 can also realize vertical washing, realizing a three-dimensional washing effect; in addition, the clothes rubbing part 221 of the clothes rubbing piece 22 can also be used to scrub the clothes in the washing chamber, thereby improving the cleaning ratio of the clothes.
[0054] Furthermore, if Figure 4 As shown, the washing assembly further includes: a guide 25, which is disposed below the impeller 21, and is used to guide the washing piece 22 to move up and down during the rotation of the impeller 21. Thus, the washing piece 22 can be moved up and down relative to the impeller 21 by using the guide 25. For example, the washing piece 22 can be slidably disposed on the guide 25, and when the washing piece 22 rotates with the impeller 21, the washing piece 22 moves along the guide 25. At this time, when the guide surface of the guide 25 is uneven on the sliding path of the washing piece 22, the washing piece 22 can be moved up and down.
[0055] Furthermore, if Figure 4 As shown, the lower end of the washing piece 22 may be provided with a driving part 223, the driving part 223 is located below the pulsator 21, and the driving part 223 is suitable for cooperating with the guide member 25 to drive the washing piece 22 to move up and down. In other words, the lower end of the washing piece 22 is provided with a driving part 223 for driving the washing piece 22 to move up and down, and the driving part 223 converts the rotation force of the washing piece 22 itself into a driving force for the washing piece 22 to move up and down by cooperating with the guide member 25, thereby driving the washing piece 22 to move up and down. As a result, the structure is simple, and there is no need to set a motor that independently drives the washing piece 22 to move up and down, thereby reducing costs.
[0056] According to the pulsator assembly 2 of the embodiment of the present invention, during the rotation of the pulsator 21 and the scrubbing piece 22, the driving part 223 of the scrubbing piece 22 can move in coordination with the guide piece, thereby driving the scrubbing piece 22 to move up and down, thereby utilizing the scrubbing piece 22 to scrub clothes up and down, thereby improving the cleaning ratio of clothes.
[0057] In addition, by providing the guide portion 251 for realizing the up and down movement of the clothes-washing piece 22, it is possible to omit the need for a motor for driving the clothes-washing piece 22 to move up and down, thereby reducing parts and components and lowering costs.
[0058] In a specific embodiment, the guide member is provided with a guide portion, and the guide portion 251 can be formed as a guide surface, and of course, the guide portion 251 can also be formed as a guide rail, and the driving portion 223 can be formed as a roller suitable for rolling on the guide surface or the guide rail. In this way, the free sliding of the driving portion 223 on the guide portion 251 can be easily achieved, the friction between the driving portion 223 and the guide portion 251 can be reduced, and the up and down movement of the washing member 22 can be achieved more easily.
[0059] In some embodiments of the present invention, reference Figure 4 , the guide part 251 can be formed into a ring shape connected end to end in the circumferential direction of the impeller 21, and the guide part 251 extends up and down in the circumferential direction of the impeller 21. That is to say, the guide part 251 is formed into a complete ring shape along the circumference of the impeller 21, and the guide part 251 extends up and down in the circumferential direction of the impeller 21. In this way, when the washing member 22 rotates, since the guide part 251 extends up and down in the circumferential direction of the impeller 21, the driving part 223 can slide up and down on the guide part 251 during the rotation process, thereby driving the washing member 22 to move up and down, and realizing the washing member 22 to move up and down relative to the impeller 21. In this way, the washing member 22 is used to wash clothes up and down.
[0060] Further, refer to Figure 4 The guide part 251 may include at least two undulating sections, which are arranged at intervals in the circumferential direction of the impeller 21, and each undulating section includes an ascending inclined surface and a descending inclined surface connected in the circumferential direction of the impeller 21. In the circumferential direction of the impeller 21, the vertical height of the ascending inclined surface gradually increases, and the vertical height of the descending inclined surface gradually decreases. In this way, when the driving part 223 moves along the undulating section, when the driving part 223 moves to the ascending inclined surface, the driving part 223 climbs up and drives the washing piece 22 to move upward. When the driving part 223 moves to the descending inclined surface, the driving part 223 descends down and drives the washing piece 22 to retract downward, thereby realizing the up and down movement of the washing piece 22.
[0061] Among them, the connecting position of the upward inclined surface and the downward inclined surface in the undulating section forms the crest of the guide part 251, and the middle position of two adjacent undulating sections forms the trough of the guide part 251. The driving part 223 passes through multiple crests and troughs in sequence in the circumferential direction of the impeller 21 to realize up and down undulating movement.
[0062] In some embodiments of the present invention, the number of the washing pieces 22 provided on the impeller 21 may be multiple, and the multiple washing pieces 22 are evenly spaced in the circumferential direction of the impeller 21, and the number of the undulating sections of the guide portion 251 may also include multiple, and the multiple undulating sections are evenly spaced in the circumferential direction of the impeller 21. Wherein, when the number of washing pieces 22 is equal to the number of undulating sections, or the number of undulating sections is an integral multiple of the number of washing pieces 22, in the process of washing clothes, the multiple washing pieces 22 synchronously pass through the undulating sections located below them, and at this time, the washing process of the multiple washing pieces 22 is synchronized, that is, they rise and fall at the same time, and the heights are consistent. When the number of washing pieces 22 is not equal to the number of undulating sections, or the number of undulating sections is not an integral multiple of the number of washing pieces 22, the washing process of the multiple washing pieces 22 is not synchronized, and the heights of the multiple washing pieces 22 are inconsistent at the same time.
[0063] In some specific embodiments, referring to Figure 4 The guide member 25 may include a plurality of guide members 25, and the plurality of guide members 25 are sequentially arranged in the circumferential direction of the pulsator 21. For example, the plurality of guide members 25 may be arranged at intervals in the circumferential direction of the pulsator 21, or the plurality of guide members 25 may be arranged end to end in the circumferential direction of the pulsator 21. In this way, when the pulsator 21 rotates one circle, the washing member 22 periodically moves up and down on the plurality of guide members 25 in sequence. Thus, the frequency of the up and down movement of the washing member 22 can be further increased, and the washing frequency can be increased.
[0064] Furthermore, if Figure 4 As shown, in the circumferential direction of the impeller 21, the driving portion 223 extends from one end of the guide member 25 (eg Figure 4 ) to the other end (eg Figure 4 The driving unit 223 drives the scrubbing member 22 to move up and down periodically at least once. It should be noted that one up and down movement of the scrubbing member 22 is one cycle of the scrubbing member 22 in the up and down direction. That is to say, when the driving unit 223 moves along the guiding unit, the driving unit 223 can drive the scrubbing member 22 to move up and down once, twice or more than twice. In this way, the number of up and down cycle movements of the scrubbing member 22 can be controlled, so that the frequency of scrubbing the clothes in the washing chamber can be determined to improve the washing degree.
[0065] In a specific example, if Figure 4As shown, the guide member 25 may include a guide surface that undulates up and down in the circumferential direction of the impeller 21, that is, the guide member 25 includes a guide surface, and the guide surface undulates up and down in the circumferential direction of the impeller 21. Further, the driving part 223 is a roller, and the roller is suitable for rolling on the guide surface. In this way, when the impeller 21 rotates, the impeller 21 drives the clothes-washing piece 22 to rotate together, and at the same time, the roller of the driving part 223 under the clothes-washing piece 22 rolls with the guide surface of the guide member 25. In other words, the roller always rolls on the guide surface. Since the guide surface undulates up and down, the roller rolls up and down on the guide surface, thereby driving the clothes-washing piece 22 to move up and down in the process of rotating with the impeller 21, so as to achieve washing clothes.
[0066] In some examples, such as Figure 4 As shown, during the up-and-down movement of the washing piece 22, the driving part 223 is always in contact with the guide surface. Thus, it can be ensured that the driving part 223 and the guide surface are always in real-time cooperation, and the up-and-down movement of the washing piece 22 is achieved. For example, when the driving part 223 moves uphill on the guide surface, the driving part 223 abuts against the guide part 251 to push the washing piece 22 to move upward. When the driving part 223 moves to the downward slope of the guide surface, the driving part 223 also keeps in contact with the guide surface to ensure that the driving part 223 can move downward along the downward slope, driving the washing piece 22 to move downward.
[0067] According to some embodiments of the present invention, Figure 7 As shown, the upper surface of the impeller 21 may be formed with upwardly protruding water-diverting ribs 212, which extend radially along the impeller 21. The water-diverting ribs 212 may include a plurality of water-diverting ribs 212, which are arranged at intervals along the circumference of the impeller 21. When the impeller 21 rotates, the water-diverting ribs 212 rotate to form a driving force, diverting the water flow for rotating and washing clothes.
[0068] Furthermore, if Figure 7 As shown, the washing piece 22 may include a plurality of washing pieces 22, which are arranged at intervals along the circumference of the impeller 21, and the washing pieces 22 and the water-repelling ribs 212 are arranged alternately in the circumference of the impeller 21. That is, a washing piece 22 is provided between each two adjacent water-repelling ribs 212, and a water-repelling rib 212 is formed between each two adjacent washing pieces 22, thereby further enhancing the washing ability of the clothes and improving the washing ratio.
[0069] In one embodiment of the present invention, Figure 3As shown, the pulsator 21 can be configured to drive the washing piece 22 to move in the up and down direction during the rotation process. In other words, when the pulsator 21 rotates, the rotation of the pulsator 21 can be converted into a driving force for driving the washing piece 22 to move back and forth in the up and down direction. Thus, it is possible to avoid directly setting a driving element (such as a motor or a driving cylinder, etc.) for driving the washing piece 22 to move up and down, thereby simplifying the structure and reducing the cost.
[0070] For example, a transmission assembly may be provided between the impeller 21 and the clothes-washing piece 22 . The transmission assembly is connected between the impeller 21 and the clothes-washing piece 22 , and the transmission assembly may convert the rotational motion of the impeller 21 in the horizontal plane into the linear motion of the clothes-washing piece 22 in the vertical direction.
[0071] Of course, the present invention is not limited to this. In other embodiments of the present invention, the impeller assembly 2 may further include a clothes-washing driving member, which may be a motor connected to the clothes-washing member 22 for driving the clothes-washing member 22 to move in the up and down directions.
[0072] According to some embodiments of the present invention, Figure 5 and Figure 8 As shown, the washing part 221 can be formed as a washing board, and a raised washing rib 2211 can be formed on at least one side surface of the washing board in the thickness direction. In other words, the washing part can be formed as a washing board in the shape of a plate, and the washing board is vertically (for example Figure 8 The washboard has two side surfaces in the thickness direction, and at least one of the two side surfaces is formed with a raised wash bar 2211. Specifically, the washboard may be formed with a wash bar 2211 on only one side surface in the thickness direction, and the wash piece 22 may also be formed with a wash bar 2211 on both side surfaces in the thickness direction. In this embodiment, by providing a wash part 221 formed in the shape of a plate body and forming a raised wash bar 2211, when the wash part 221 moves relative to the clothes, the clothes can be washed and rubbed, and the washing effect is better.
[0073] Furthermore, if Fig.14 As shown, the width of the washboard can be gradually reduced from bottom to top, thereby gradually reducing the width of the upper part of the washboard and reducing the space occupied by the washboard in the washing chamber. In addition, the washing section 221 with a gradually reduced width can also prevent clothes from being entangled on the washing section 221 during the washing process.
[0074] Furthermore, in the direction perpendicular to the thickness of the rubbing part 221, the outer contour of the rubbing part 221 is generally formed into a triangular shape. And the arc transition between the adjacent outer surfaces of the rubbing part 221, so that when there are a lot of clothes in the washing chamber, the triangular shaped rubbing part 221 has a small resistance and less wear on the clothes. In this embodiment, by setting the rubbing part 221 to a triangular shape, the wear of the clothes by the rubbing part 221221 during the washing process can be reduced. At the same time, when the load is heavy, compared with other shapes (such as a rectangle), the water resistance is smaller, which is conducive to increasing the agitation of the washing water flow and improving the washing ratio.
[0075] like Fig.14 As shown, the washboard is formed into a plate shape extending in the vertical direction, and the width of the washboard gradually decreases from bottom to top. Specifically, in the projection plane perpendicular to the thickness direction of the washboard, the outer contour of the washboard 221 is generally formed into an isosceles trapezoid or an isosceles triangle. Such a design can reduce the wear of the clothes by the washboard 221 during the washing process. At the same time, when the load is large, the water resistance is smaller than that of other shapes (such as rectangles), which is conducive to increasing the agitation of the washing water flow and improving the cleaning ratio. The washboard 221 has two opposite surfaces in the thickness direction formed with washboard rubbing bars 2211, wherein the washboard rubbing bars 2211 can include multiple, and the multiple washboard rubbing bars 2211 are evenly spaced or staggered on the washboard. The washboard rubbing bars 2211 can extend in the vertical direction, the washboard rubbing bars 2211 can also extend in the horizontal direction or in a direction inclined relative to the horizontal direction. Of course, the washboard rubbing bars 2211 can also extend in the vertical and horizontal directions. For example, a plurality of clothes-rubbing ribs 2211 are formed on both side surfaces of the clothes-rubbing portion 221 , and the plurality of clothes-rubbing ribs 2211 on each side surface extend in the horizontal direction and are evenly spaced in the vertical direction.
[0076] Further, in a projection plane perpendicular to the central axis of the impeller 21, the clothes-rubbing bar 2211 may extend along the circumference of the impeller 21, wherein the clothes-rubbing bar 2211 may extend along a straight line in the circumferential direction of the impeller 21, and the clothes-rubbing bar 2211 may also extend along an arc in the circumferential direction of the impeller 21. Of course, the present invention is not limited thereto, and the user may reasonably set the specific structure and extension direction of the clothes-rubbing bar 2211 according to actual needs.
[0077] like Fig.14 As shown, in a specific embodiment, the upper side surface of the clothes washing part 221 is formed as an arc-shaped surface convex upwards. Thus, clothes can be prevented from being entangled on the top of the clothes washing part 22.
[0078] According to some specific embodiments of the present invention, Figure 5 As shown, the impeller 21 may be provided with a mounting seat 23, and the mounting seat 23 is formed with a guide hole 231, and the guide hole 231 is along the vertical direction (for example Fig.12 ), and the guide hole 231 passes through the upper end surface of the mounting seat 23, the clothes-rubbing member 22 is arranged in the guide hole 231, and the clothes-rubbing portion 221 extends upward from the guide hole 231. In other words, the mounting seat 23 is formed with a guide hole 231 for mounting the clothes-rubbing portion 221, and the guide hole 231 is used to guide the clothes-rubbing portion 221 during the process of moving up and down. Therefore, the guide hole 231 can play a guiding role, ensuring that the clothes-rubbing portion 221 does not tilt during the process of moving up and down in the vertical direction, and ensuring the stability of the clothes-rubbing member during the movement.
[0079] Furthermore, if Fig.12 As shown, a guide rib 232 may be formed on the peripheral wall of the guide hole 231. The guide rib 232 protrudes from the inner peripheral wall of the guide hole 231 toward the inner side of the guide hole 231, and the guide rib 232 extends vertically from one end of the guide hole 231 (for example, Fig.12 ) extends to the other end (eg, Fig.12 In this embodiment, by providing the guide rib 232 in the guide hole 231, the gap between the guide rib 232 and the outer surface of the clothes rubbing part 221 can be made smaller, the guiding effect is better, and the stability of the clothes rubbing part 221 in the process of moving up and down is further improved.
[0080] like Fig.12 and Fig.13 As shown, the mounting seat 23 is integrally formed, and the mounting seat 23 includes an inner ring portion and an outer ring portion which are arranged inside and outside, the inner and outer portions and the outer ring portion are both formed into an annular cylindrical shape and extend vertically, the inner ring portion is arranged on the inner side of the outer ring portion, and an end plate portion is connected between the top of the inner ring portion and the top of the outer ring portion, the end plate portion is formed into an annular plate shape extending in a horizontal plane, the inner circumferential edge of the end plate portion is connected to the upper end edge of the inner ring portion, and the outer circumferential edge of the end plate portion is connected to the upper end edge of the outer ring portion.
[0081] like Fig.13 As shown, the inner side of the inner ring portion defines a guide hole 231 extending in the vertical direction, and the cross section of the guide hole 231 is generally formed in a rectangular shape. The inner surface of the inner ring portion is formed with a guide rib 232 protruding toward the inside, and the guide rib 232 extends vertically from the lower end of the inner ring portion to the upper end of the inner ring portion. The guide rib 232 includes a plurality of guide ribs 232, and the plurality of guide ribs 232 are arranged at intervals in the circumferential direction of the inner ring portion. Preferably, the end surface of the guide rib 232 located in the guide hole 231 is formed as a guide plane extending in the vertical direction, and the guide plane is suitable for providing guidance for the rubbing part 221 during the up and down movement. Further, the cross section of the guide rib 232 can be generally formed in a rectangular shape.
[0082] like Fig.12As shown, in the direction from top to bottom, the outer ring portion is formed into a plate shape extending downward and away from the inner ring portion. Further, the mounting seat 23 also includes a reinforcing plate, which is formed into a plate shape extending vertically, and the reinforcing plate extends in a length direction parallel to the guide hole 231. The reinforcing plate is arranged between the inner ring portion and the outer ring portion and is connected to the inner ring portion and the outer ring portion respectively. The reinforcing plates include two, and the two reinforcing plates are respectively arranged on both sides of the width direction of the inner ring portion.
[0083] In a specific example, if Fig. 9 As shown, a limiting protrusion 234 may be provided on the inner peripheral wall of the guide hole 231, and the limiting protrusion 234 is formed by the inner peripheral wall of the guide hole 231 protruding inwardly, and a limiting boss 222 protruding outwardly in the horizontal direction is formed on the outer surface of the washing piece 22. When the washing piece 22 moves upward to the maximum height relative to the pulsator 21, the limiting boss 222 abuts against the lower side of the limiting protrusion 234. Therefore, the limiting boss 222 cooperates with the limiting protrusion 234 to limit the maximum displacement of the washing piece 22 moving upward, and prevent the washing piece 22 from moving excessively upward and escaping from the guide hole 231.
[0084] like Fig. 9 , Fig.12 and Fig.14 As shown, a limiting protrusion 234 is formed on the mounting seat 23, and the limiting protrusion 234 is formed on the circumference of the upper end of the guide hole 231. The limiting protrusion 234 includes two, and the two limiting protrusions 234 extend in the horizontal direction. The two limiting protrusions 234 are respectively located at the two end edges of the length direction of the guide hole 231. A limiting boss 222 is formed on the washing piece 22. The limiting boss 222 includes two, and the two limiting bosses 222 correspond to the two limiting protrusions 234 one by one. The two limiting bosses 222 extend in the horizontal direction in directions away from each other. The washing piece 22 can move between the lowest position and the highest position in the up-down direction. When the washing piece 22 moves upward to the highest position, the upper end surface of the limiting boss 222 contacts the lower end surface of the limiting protrusion 234.
[0085] In a specific example, the rubbing member 22 can move up and down between the highest position and the lowest position. When the rubbing member 22 moves to the highest position, the rubbing portion 221 of the rubbing member 22 extends upward from the guide hole. When the rubbing member 22 is at the lowest position, at least part of the rubbing portion 221 retracts downward into the guide hole. Preferably, when the rubbing member 22 moves downward to the lowest position, part of the rubbing portion 221 (for example, the lower part of the rubbing portion 221) retracts downward into the guide hole. Thus, not only the moving distance of the rubbing member 22 in the up and down direction is increased, and the washing force of the clothes is increased, but also when the rubbing member 22 moves downward, the rubbing member 22 partially retracts into the guide hole, which can also reduce the rotational resistance of the clothes and the water flow in the circumferential direction. In addition, the rubbing portion 221 partially retracts into the guide hole, and it can also prevent the rubbing portion 221 from completely retracting into the guide hole so that the clothes fall into the gap between the rubbing portion 221 and the guide hole.
[0086] In some specific examples of the present invention, Figure 5 and Figure 6 As shown, the pulsator 21 can be detachably connected to the mounting seat 23. Thus, the mounting seat 23 can be easily installed and removed, and the installation and removal of the clothes washing member 22 are also convenient, so that maintenance and replacement are convenient.
[0087] like Figure 5 and Figure 6 As shown, the impeller 21 may be formed with a first fixing hole 211 that vertically passes through the impeller 21, and the mounting seat 23 may be formed with a second fixing hole 233. The mounting seat 23 is connected to the impeller 21 by screws passing through the first fixing hole 211 and the second fixing hole 233. Specifically, the mounting seat 23 may be arranged on the upper side of the impeller 21, and a plurality of second fixing holes 233 may be formed on the mounting seat 23. The plurality of second fixing holes 233 may be arranged at intervals around the circumference of the inner ring portion, for example Fig.13 As shown in , a plurality of fixing columns are provided between the inner ring portion and the outer ring portion, and the plurality of fixing columns are symmetrically arranged on both sides of the width direction of the inner ring portion, and a second fixing hole 233 is formed on each fixing column. A plurality of first fixing holes 211 are provided on the impeller 21, and the plurality of first fixing holes 211 correspond to the plurality of second fixing holes 233 one by one and are opposite to each other up and down. The first fixing holes 211 on the impeller 21 are all formed as countersunk holes, and screws pass through the first fixing holes 211 and the second fixing holes 233 from bottom to top to realize the connection between the impeller 21 and the mounting seat 23.
[0088] According to some embodiments of the present invention, referring to Figure 4 As shown, the clothing processing device 100 may include a washing tub 1 and a water tub arranged inside and outside, a balancing ring may be provided on the top of the washing tub 1, and a impeller assembly 2 is arranged on the inner side of the washing tub 1. The clothing processing device 100 also includes a driving motor 3, which is connected to the washing tub 1 and the impeller assembly 2 and is used to drive the washing tub 1 and / or the impeller assembly 2 to rotate.
[0089] Furthermore, the guide member 25 can be arranged at the bottom of the washing tub 1. The guide member 25 can be integrally formed with the washing tub 1 or separately arranged. When the guide member 25 and the washing tub 1 are separately arranged, the guide member 25 and the washing tub 1 can be detachably connected, such as by snap-fitting or screwing.
[0090] According to some embodiments of the present invention, the washing assembly may further include: a reset elastic member 28, which has a force that always drives the driving part 223 to contact the guide member 25. Thus, the elastic force of the reset elastic member 28 can be used to push the driving part 223 to move toward the guide member 25, ensuring that the driving part 223 and the guide surface always cooperate in real time, with higher reliability and better stability of the up and down periodic movement of the washing member 22.
[0091] According to some embodiments of the present invention, Fig.14 and Fig.15 As shown, the washing piece 22 may further include: a main body 224 connected to the lower end of the washing part 221, a first connecting hole 2241 extending upward may be formed on the lower side surface of the main body 224, the pulsator 21 is provided with a second connecting hole 213 penetrating the pulsator 21, and the washing piece 22 is movably connected to the pulsator 21 through the first connecting hole 2241 and the second connecting hole 213 via a fastener 26. Thus, the washing piece 22 and the pulsator 21 can be easily installed and removed, and the washing piece 22 can be easily repaired and replaced.
[0092] In some examples, the first connection hole 2241 may be formed as a threaded hole. The fastener 26 may be a bolt, and a threaded connection section of the bolt may extend into the first connection hole 2241 and be connected to a peripheral wall of the first connection hole 2241 .
[0093] In other examples, such as Fig.17 As shown, a connecting nut 27 may be embedded in the first connecting hole 2241, and the connecting nut 27 is integrally injection molded with the main body 224. Thus, the connection reliability between the connecting nut 27 and the main body 224 can be improved, and at the same time, the connection reliability between the connecting nut 27 and the fastener 26 can be ensured.
[0094] like Figure 14-16As shown, the outer contour of the main body 224 of the washing member 22 is formed in a rectangular parallelepiped shape, and two first connection holes 2241 arranged at intervals are formed at the bottom of the main body 224. The two first connection holes 2241 are symmetrically arranged in the length direction of the main body 224. The inner sides of the two first connection holes 2241 are both embedded with connection nuts 27. The connection nuts 27 are located at the end of the first connection holes 2241 close to the pulsator 21, and the lower end edge of the connection nut 27 is spaced a predetermined distance from the lower end edge of the first connection hole 2241. Two second connection holes 213 corresponding to the two first connection holes 2241 are formed on the pulsator 21, and the two second connection holes 213 penetrate the pulsator 21 in the up-down direction. The fastener 26 passes through the second connection hole 213 and the first connection hole 2241 in sequence from bottom to top, and is threadedly connected with the connection nut 27 located in the first connection hole 2241.
[0095] According to some specific embodiments of the present invention, Fig. 9 As shown, the washing piece 22 may further include: a reset elastic member 28, the reset elastic member 28 is connected between the impeller 21 and the fastener 26, that is, the fastener 26 is connected to the impeller 21 through the reset elastic member 28. In this way, when the impeller 21 rotates, since the guide portion 251 that fluctuates up and down is provided below the impeller 21, the driving portion 223 (such as a roller) provided on the guide portion 251 will move up and down. Since the impeller 21 has only one degree of freedom of rotation and no degree of freedom of up and down, when the roller goes uphill, the washing piece 22 will compress the reset elastic member 28, overcome the force of the reset elastic member 28 and extend upward. When the roller goes downhill, the washing piece 22 will retract downward under the action of the reset elastic member 28, so that the washing piece 22 can stretch and retract up and down to wash the clothes when the impeller 21 rotates, thereby improving the washing ratio.
[0096] In some specific examples, such as Fig. 9 As shown, a positioning groove 214 that is recessed upward may be formed on the impeller 21, a second connecting hole 213 is formed on the top wall of the positioning groove 214, and the resetting elastic member 28 may be formed as a spring, the spring is sleeved on the fastener 26, and the upper end of the spring is fixed in the positioning groove 214, or the upper end of the spring abuts against the top wall of the positioning groove 214, and the lower end of the spring is fixed on the fastener 26. In this embodiment, by setting the positioning groove 214, the spring can be positioned in the positioning groove 214, and the positioning groove 214 can not only play a role in limiting the movement of the spring in the horizontal plane, but also facilitate the assembly of the spring and improve the assembly efficiency. At the same time, by sleeve-arranging the spring on the fastener 26, the fastener 26 can provide guidance during the deformation of the spring, prevent the spring from being skewed and deformed, and ensure the stability of the washing piece 22 during the up and down movement.
[0097] Furthermore, the lower end of the fastener 26 may be provided with a flange 261 protruding radially outward, and the lower end of the spring is connected to the flange 261, or the lower end of the spring abuts against the upper surface of the flange 261. The flange 261 may be formed in an annular shape, and the maximum radial dimension of the flange 261 in the horizontal direction is larger than the radial dimension of the spring, so that the spring can always be confined between the flange 261 and the bottom wall of the positioning groove 214, preventing the spring from falling off from the lower end of the fastener 26.
[0098] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, a through hole 215 which vertically penetrates the pulsator 21 may be formed on the pulsator 21, and the clothes-washing part 22 may further include: a connecting rod 225, the connecting rod 225 extending vertically, the upper end of the connecting rod 225 connected to the clothes-washing part 221, the lower end of the connecting rod 225 passing through the through hole 215, and the driving part 223 connected to the lower end of the connecting rod 225. Thus, the connecting rod 225 can connect the clothes-washing part 221 located above the pulsator 21 with the driving part 223 located below the pulsator 21, and the structure is compact, so as to avoid occupying the washing space above the pulsator 21.
[0099] In some specific examples, such as Fig. 9 and Fig.14 As shown, the lower end of the connecting rod portion 225 can be formed with two relatively arranged fixing plates 2252, and an axial hole is formed on the fixing plate 2252. The two axial holes are provided with fixing shafts 2251, and the fixing shafts 2251 extend in the horizontal direction. The driving portion 223 is rotatably mounted on the fixing shafts 2251. For example, the driving portion 223 is formed as a roller, and the roller is mounted on the fixing shaft 2251.
[0100] Optionally, the connecting rod portion 225 can be connected to the main body portion 224 of the clothes washing member 22 by welding.
[0101] Furthermore, if Fig.15 As shown, two first connection holes 2241 may be formed on the main body 224, and the two first connection holes 2241 are symmetrically arranged on both sides of the connecting rod 225. In this way, the clothes washing member 22 can be subjected to a more uniform force during the up and down movement.
[0102] In a specific embodiment, an upwardly concave shaft hole is formed on the lower surface of the impeller 21, and the shaft hole is used to connect the drive motor 3. A spline is embedded in the shaft hole, and the impeller 21 is connected to the drive shaft of the drive motor 3 through the spline. Preferably, the spline and the impeller 21 are integrally injection molded.
[0103] During the installation of the impeller assembly 2 of the embodiment of the present invention, the guide member 25 is first installed on the bottom of the washing tub 1, specifically, the guide member 25 is installed on the bottom of the washing tub 1 by screws or welding. Then, the clothes-washing member 22 and the impeller 21 are assembled. Specifically, the roller is first installed on the connecting rod 225 of the clothes-washing member 22, and then the connecting rod 225 is welded to the main body 224 of the clothes-washing member 22, and then the clothes-washing member 22 is inserted into the guide hole 231 of the mounting seat 23, and then the clothes-washing member 22 and the mounting seat 23 are installed together on the front of the impeller 21, and the mounting seat 23 is fixed on the back of the impeller 21 by screws; then the spring is sleeved on the fastener 26, and then the spring is inserted into the positioning groove 214, and the fastener 26 is inserted into the first connecting hole 2241 and the second connecting hole 213 and threadedly connected with the connecting nut 27. Finally, the impeller assembly 2 is installed on the impeller 21 shaft of the clutch of the laundry processing device 100 and fixed with screws.
