[0044] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0045] Please see Figures 1 to 5 This application provides a washing device, including a washing drum 200 and a pulsator assembly 100 according to any embodiment of this application. A clothes handling chamber 210 is provided inside the washing drum 200. The pulsator assembly 100 is rotatably disposed within the washing drum 200.

[0046] It should be noted that the washing equipment can be an agitator washing machine, a top-loading washing machine, a washer-dryer combo, etc., and there are no restrictions here.

[0047] The washing drum 200 is used to hold laundry items, such as clothes, shoes, carpets, etc. The top side of the washing drum 200 has an opening through which the user can put in or take out laundry items.

[0048] Taking an agitator-type washing machine as an example, the agitator-type washing machine may only include a washing drum 200. In this case, the washing drum 200 can hold both washing water and clothes. The agitator-type washing machine may also include an outer drum, with the washing drum 200 disposed inside the outer drum. The outer drum is used to hold washing water, and the washing drum 200 is used to hold clothes. Of course, in some embodiments, the agitator-type washing machine may include a washing drum 200 and an outer drum. The washing drum 200 can hold both washing water and clothes, and the water in the washing drum 200 will not enter the outer drum.

[0049] The impeller assembly 100 is rotatably disposed within the washing drum 200. It is understood that the impeller assembly 100 rotates when the washing device is in the washing state. For example, in some embodiments, the washing device includes a motor and a reducer, the motor shaft of which drives the impeller assembly 100 to rotate via the reducer to wash the laundry.

[0050] The rotation direction of the impeller assembly 100 is not limited. For example, it can rotate clockwise and counterclockwise. Clockwise and counterclockwise rotation are only used to indicate that the rotation directions are opposite and do not specifically refer to any particular direction.

[0051] It should be noted that during the washing process, the impeller assembly 100 rotates, while the washing drum 200 may or may not rotate; there is no restriction on this.

[0052] Please see Figures 3 to 11 This application provides a pulsator assembly 100, which includes a pulsator 10, a transmission assembly 30, and at least one washbasin 20. The pulsator 10 has a plurality of water-spraying ridges 11 protruding from its surface, spaced apart. The washbasin 20 is rotatably disposed on the pulsator 10 and located between adjacent water-spraying ridges 11. The pulsator 10 is connected to the washbasin 20 via the transmission assembly 30; wherein, the pulsator 10 rotates to drive the washbasin 20 to rotate around its rotation center, and the transmission assembly 30 drives the washbasin 20 to rotate on its own axis.

[0053] For example, the impeller assembly 100 also includes a scrubbing stick 40 disposed on the impeller 10, which is located at the bottom of the washing drum 200, and the scrubbing stick 40 extends along the height direction of the washing device.

[0054] The specific structure of the impeller 10 is not limited. For example, such as... Figure 3 As shown, the upper surface of the impeller 10 is provided with multiple water-dispelling ridges 11. During the rotation of the impeller 10, the water-dispelling ridges 11 agitate the water flow and the washings, thereby enhancing the agitation effect on the water flow.

[0055] The specific shape of the impeller 10 is not limited. For example, the impeller 10 can be a circular structure, which facilitates the rotation of the impeller 10.

[0056] It should be noted that the height of the washing equipment is basically parallel to the axial direction of the wash stick 40.

[0057] The axial direction of the wash stick 40 is as follows Figure 7 As shown in L.

[0058] The axial direction of the wash stick 40 is its extension direction. When used in a washing machine, the axial direction of the wash stick 40 is basically parallel to the height direction of the washing machine.

[0059] The cross-sectional shape of the wash stick 40 in a plane perpendicular to its axis is not limited. For example, it can be elliptical, polygonal, circular, or other irregular shapes.

[0060] The connection method between the wash stick 40 and the impeller 10 is not limited. For example, the wash stick 40 and the impeller 10 are separate structures. The separate wash stick 40 and the impeller 10 can be fastened together by bolts, screws or other fasteners, or connected by welding, snap-fit ​​or other methods.

[0061] For example, the bottom of the wash stick 40 is connected to the impeller 10, and the internal space of the wash stick 40 is connected to the internal space of the impeller 10. That is to say, the liquid in the internal space of the wash stick 40 can flow to the back of the impeller 10, and then return to the washing drum 200 under the agitation of the water-spraying ridge 11 on the back of the impeller 10.

[0062] The wash stick 40 is detachably connected to the impeller 10, which facilitates the maintenance, replacement or cleaning of the wash stick 40.

[0063] The number of washbasins 20 can be one or more.

[0064] In the embodiments of this application, "multiple" refers to two or more items.

[0065] As the impeller 10 rotates, the washbasin 20 agitates the water and the laundry, enhancing the agitation of the water flow and scrubbing the clothes, thus improving the washing effect.

[0066] The specific shape of the washbasin 20 is not limited. For example, the washbasin 20 can be a circular structure, which facilitates the rotation of the washbasin 20.

[0067] The washbasin 20 is rotatably mounted on the impeller 10, meaning that the washbasin 20 can rotate relative to the impeller 10, which helps to further enhance the agitation and scrubbing effect of the water flow.

[0068] The impeller 10 is connected to the washbasin 20 via the transmission assembly 30. In other words, the washbasin 20 does not require external power supply when rotating, thus achieving passive rotation of the washbasin 20.

[0069] The impeller assembly 100 of this application embodiment features a scrubbing disc 20 mounted on an impeller 10. The scrubbing disc 20 is positioned between adjacent water-spreading ridges 11. The impeller 10 can drive the scrubbing disc 20 to rotate around its rotation center, thereby improving the washing effect by scrubbing clothes. Furthermore, during the rotation of the impeller 10 and the scrubbing disc 20, the impeller 10 can also drive the scrubbing disc 20 to rotate via a transmission assembly 30, resulting in high-speed rotation of the scrubbing disc 20 to further scrub clothes and improve the washing effect. In this embodiment, the impeller 10 drives the scrubbing disc 20 to rotate via the transmission assembly 30, achieving passive rotation of the scrubbing disc 20. This means the scrubbing disc 20 does not require external power during rotation, reducing the number of components while improving the washing effect by enabling both rotation and revolution of the scrubbing disc 20.

[0070] The specific structure of the transmission component 30 is not limited.

[0071] In some embodiments, please refer to Figures 3 to 5 The transmission assembly 30 includes a rotating shaft 31 and a meshing gear ring 32 and a gear 33. The washboard 20 is rotatably mounted on the impeller 10 via the rotating shaft 31. The gear 33 is fixed to the rotating shaft 31. The impeller 10 rotates to drive the gear 33 to rotate around the gear ring 32.

[0072] In other words, as long as the impeller 10 rotates, it can drive the washbasin 20 to rotate. There is no need to set up a control device to control the washbasin 20, nor is there a need to set up an external power source to power the washbasin 20.

[0073] For example, the gear ring 32 is fixed to the bottom of the washing drum 200, the wash disc 20 is rotatably mounted on the impeller 10 via the rotating shaft 31, and the gear 33 is fixed on the rotating shaft 31. The gear ring 32 and the gear 33 mesh with each other. In this way, the impeller 10 drives the wash disc 20 mounted on the impeller 10 to rotate, so that the gear 33 rotates around the gear ring 32, which can realize the high-speed rotation of the wash disc 20, thereby realizing the passive rotation of the wash disc 20. This structure is simple and reliable.

[0074] The specific number of water-splashing ridges 11 and washbasins 20 is not limited here.

[0075] In some embodiments, please refer to Figures 3 to 5There are multiple washboards 20, and each washboard 20 is alternately arranged with each water-spraying ridge 11. Each washboard 20 corresponds to a gear 33 and a rotating shaft 31. All gears 33 are arranged at intervals along the gear ring 32.

[0076] In other words, all the washbasins 20 share a single gear ring 32, so that the corresponding gears 33 of all the washbasins 20 surround the circumference of the gear ring 32. This helps to reduce the number of parts and improve the compactness and stability of the structure.

[0077] For example, there are three water-splashing ridges 11 and three washbasins 20, which are arranged alternately. This helps to enhance the agitation and washing effect of the water flow.

[0078] In some embodiments, please continue reading Figures 3 to 5 The surface of the impeller 10 is recessed to form a groove 12, at least a portion of the washbasin 20 is accommodated in the groove 12, the bottom wall of the groove 12 is provided with a through hole 13, the rotating shaft 31 is provided through the through hole 13, and the gear 33 is provided on the side of the impeller 10 away from the washbasin 20.

[0079] For example, the transmission assembly 30 includes a bushing 34, which is fixed at the through hole 13, and the rotating shaft 31 passes through the bushing 34 to achieve rotation relative to the impeller 10.

[0080] For example, the lowest point of the edge of the washbasin 20 is not higher than the groove 12.

[0081] For example, the highest point of the edge of the washbasin 20 is not higher than the groove 12, that is, the highest point of the edge of the washbasin 20 does not protrude from the groove 12.

[0082] The surface of the impeller 10 is recessed to form a groove 12. By accommodating at least a portion of the washbasin 20 in the groove 12, the edge of the washbasin 20 can be accommodated in the groove 12. During rotation, the edge of the washbasin 20 can be prevented from getting tangled in clothing to a certain extent, thereby improving the reliability of the impeller assembly 100.

[0083] In some embodiments, please refer to Figures 6 to 8 The impeller assembly 100 also includes a wash stick 40 disposed on the impeller 10. The wash stick 40 includes a wash part 42 with lifting ribs 421 formed on its surface. The wash part 42 can move relative to the impeller 10 in the up-down direction of the impeller assembly 100.

[0084] The circumferential surface of the scrubbing part 42 is provided with lifting ribs 421. As the scrubbing stick 40 rotates with the impeller 10, the clothes can be scrubbed by the lifting ribs 421 of the scrubbing part 42, thereby improving the washing effect of the clothes.

[0085] For example, the wash section 42 may have lifting ribs 421 on some sides and no lifting ribs 421 on some sides.

[0086] The number of lifting ribs 421 is not limited here. For example, there may be one or more lifting ribs 421.

[0087] For example, multiple lifting ribs 421 are arranged along the height direction of the wash section 42.

[0088] The scrubbing part 42 can move relative to the impeller 10 along the vertical direction of the impeller assembly 100. When the impeller 10 rotates, it provides the clothes in the washing chamber with the power to tumble and the impact force of washing. Since the scrubbing stick 40 is located on the impeller 10, and the scrubbing part 42 can move vertically relative to the impeller 10, the scrubbing part 42 can rotate with the impeller 10 when the impeller 10 rotates. At the same time, the scrubbing part 42 can also move vertically. Thus, the clothes in the washing chamber can not only be washed by the rotation of the impeller 10 (i.e., the impeller 10 can achieve horizontal washing), but the scrubbing part 42 can also achieve vertical washing, achieving a three-dimensional washing effect. In addition, the scrubbing part 42 of the scrubbing stick 40 can be used to scrub the clothes in the washing chamber, thereby improving the washing effect of the clothes.

[0089] When the impeller 10 rotates in both directions, the scrubbing part 42 will be subject to the resistance of water or load, causing it to not rotate or rotate very slowly, which may affect the washing effect. Therefore, by setting the scrubbing part 42 to be able to move relative to the impeller 10 in the vertical direction of the impeller assembly 100, the scrubbing part 42 will rise or fall, impacting and patting the load, and will also generate a strong upward impact water flow to wash the load, further improving the washing effect on clothes.

[0090] Here, by setting up a scrubbing section 42 and a scrubbing disc 20, both the scrubbing section 42 and the scrubbing disc 20 can move relative to the impeller 10. The scrubbing disc 20 scrubs the clothes at the bottom of the washing drum 200, while the scrubbing section 42 scrubs the clothes in the middle of the washing drum 200, so as to achieve three-dimensional scrubbing of the clothes, that is, to scrub the clothes from multiple directions, which is conducive to improving the washing effect and washing efficiency.

[0091] In some embodiments, please refer to Figures 6 to 8 The wash stick 40 also includes a guide screw 41 and a pin 43. The guide screw 41 is connected to the impeller 10, and the wash part 42 is movably sleeved on the guide screw 41 along the vertical direction. The side wall of the guide screw 41 is recessed to form a guide groove 411, and the wash part 42 has an insertion hole 422. The pin 43 passes through the insertion hole 422 and extends into the guide groove 411, and the wash part 42 moves along the guide groove 411 through the pin 43.

[0092] For example, the scrubbing part 42 can move spirally upward relative to the guide screw 41.

[0093] In other words, the wash section 42 is connected to the impeller 10 via the guide screw 41.

[0094] For example, the inside of the scrubbing part 42 forms an installation channel, and the scrubbing part 42 is movably sleeved on the guide screw 41 through the installation channel, thereby realizing the up and down movement of the scrubbing part 42.

[0095] The scrubbing part 42 has a socket 422 that penetrates the side wall of the scrubbing part 42. Thus, by fixing the pin 43 to the scrubbing part 42, the pin 43 passes through the socket 422 and extends into the guide groove 411. The scrubbing part 42 moves along the guide groove 411 via the pin 43, thereby realizing the movement of the scrubbing part 42 relative to the guide screw 41 in the up and down direction of the impeller assembly 100.

[0096] For example, the wash stick 40 also includes a pressure plate 44, which covers the insertion hole 422 to confine the pin 43 within the insertion hole 422 and to prevent the pin 43 from scratching the clothes.

[0097] For example, the pressure plate 44 is fastened to the wash section 42.

[0098] There are various structural forms of the guide groove 411.

[0099] In some embodiments, please refer to Figure 7 and Figure 8 The guide groove 411 extends spirally upward along the side wall of the guide screw 41.

[0100] In this way, the scrubbing part 42 can move spirally upward relative to the guide screw 41, which helps to further improve the situation where the scrubbing part 42 does not rotate or rotates very slowly due to the resistance of water or load.

[0101] In some embodiments, please refer to Figure 7 The wash stick 40 also includes a first elastic element 45, and the pin 43 extends into the guide groove 411 under the elastic force of the first elastic element 45.

[0102] For example, the pin 43 is provided with a flange protruding in the circumferential direction, and the through hole 13 is formed with a stepped surface 423. The flange abuts against the stepped surface 423. In this way, the pin 43 can be limited, which can prevent the pin 43 from getting stuck due to extending too much into the guide groove 411.

[0103] For example, the first elastic element 45 may be a spring.

[0104] For example, by clamping the first elastic member 45 between the stepped surface 423 and the pressure plate 44, the pin 43 extends into the guide groove 411 under the elastic force of the first elastic member 45. During the movement of the washing part 42 relative to the guide screw 41, if the pin 43 is subjected to external force, the pin 43 can be squeezed into the insertion hole 422 and the first elastic member 45 can be compressed. This helps to improve the reliability and smoothness of the movement of the washing part 42.

[0105] In some embodiments, please refer to Figures 9 to 11 The washing equipment includes a spray plate assembly 300 disposed inside the washing drum 200. The spray plate assembly 300 includes a spray plate 310 and a washboard 320. The spray plate assembly 300 extends along the height direction of the washing drum 200, and the spray plate 310 is provided with a spray nozzle. A water spraying channel 330 communicating with the spray nozzle is formed between the spray plate 310 and the inner wall of the washing drum 200. The bottom side of the water spraying channel 330 is open. The washboard 320 is movably disposed on the spray plate 310 along the vertical direction of the spray plate 310.

[0106] During the washing process, the impeller 10 agitates the water below it. Under the action of centrifugal force, the water rushes towards the inner wall of the washing drum 200, enters the spray channel 330 through the opening, rises along the spray channel 330 and sprays out from the spray nozzle. The spray water from the spray nozzle sprays onto the clothes in the clothes treatment chamber 210, enhancing the rinsing effect of the spray water. It can quickly wet the clothes floating on the water surface and effectively rinse away residual floating foam, thus improving the washing effect.

[0107] It should be noted that the spray nozzle is positioned relatively high, allowing water to be sprayed from top to bottom onto the clothes. For example, the spray nozzle is positioned above the maximum allowable washing water level of the washing machine.

[0108] It should be noted that the maximum allowable washing water level of the washing equipment refers to the maximum water level designed for the washing equipment. During normal washing, the water level will not exceed this maximum water level.

[0109] The number of waterfall panel assemblies 300 can be one or more. In embodiments where the number of waterfall panel assemblies 300 is multiple, the multiple waterfall panel assemblies 300 are arranged at circumferential intervals along the washing drum 200.

[0110] The washboard 320 is movably mounted on the spray plate 310 along the vertical direction. When the impeller 10 rotates, the water flow rising along the spray channel 330 will push the washboard 320 upward to wash the clothes, thereby further improving the washing effect of the clothes.

[0111] For example, the spray panel 310 is provided with an opening, and the washboard 320 is movably disposed at the opening.

[0112] In some embodiments, please refer to Figures 9 to 11 The waterfall panel assembly 300 also includes a second elastic element 340, which is disposed between the waterfall panel 310 and the washboard 320. The washboard 320 moves upward under the action of water flow in the water channel 330, and the second elastic element 340 undergoes elastic deformation. The second elastic element 340 drives the washboard 320 to move downward by restoring its elastic deformation.

[0113] For example, the second elastic element 340 may be a spring.

[0114] For example, by placing the second elastic member 340 between the spray plate 310 and the washboard 320, the washboard 320 is reset by the second elastic member 340, thereby realizing up-and-down movement.

[0115] Specifically, when the impeller 10 rotates, the force exerted by the water flow rising along the water spray channel 330 on the washboard 320 is greater than the force exerted by the second elastic element 340 on the washboard 320, thereby pushing the washboard 320 to move upward. When the rotation stops, the second elastic element 340 undergoes elastic deformation, and the second elastic element 340 drives the washboard 320 to move downward by restoring its elastic deformation.

[0116] In some embodiments, please continue reading Figures 9 to 11 The washboard 320 is recessed on the side facing the water spray channel 330, so that the side of the washboard 320 away from the water spray channel 330 forms a protrusion to form a washboard protrusion 321, and the surface of the washboard protrusion 321 protrudes to form a washboard rib 322.

[0117] For example, the surface of the scrubbing protrusion 321 is provided with a plurality of scrubbing ribs 322, which are spaced apart along the height direction of the washing drum 200.

[0118] The washboard 320 has a protrusion forming a washboard protrusion 321 on the side opposite to the water spray channel 330. The surface of the washboard protrusion 321 has a protrusion forming a washboard rib 322. On the one hand, it can facilitate the washboard rib 322 of the washboard protrusion 321 to wash the clothes. On the other hand, it can also facilitate the water flow in the water spray channel 330 to impact the concave area, so as to generate an upward force on the washboard 320, thereby driving the washboard 320 to move upward.

[0119] For example, the washboard 320 may also have other areas forming a water-facing surface, so that the water flow rising along the spray channel 330 impacts the water-facing surface, thereby driving the washboard 320 to move upward.

[0120] In some embodiments, please refer to Figure 9 The washboard 320 has a first abutting surface 323 on its top and a second abutting surface 311 on its top. The two ends of the second elastic member 340 abut against the first abutting surface 323 and the second abutting surface 311, respectively.

[0121] Here, the first abutting surface 323 and the second abutting surface 311 are arranged opposite to each other so that the two ends of the second elastic member 340 abut against the first abutting surface 323 and the second abutting surface 311 respectively.

[0122] For example, the first abutment surface 323 is provided with a first guide post 324, the second abutment surface 311 is provided with a second guide post 312, and the two ends of the second elastic member 340 are respectively sleeved on the first guide post 324 and the second guide post 312 to improve the installation stability of the second elastic member 340.
