DETAILED DESCRIPTION OF THE MODALITIES

[0044] The modalities of the present disclosure will be described in Petition 870250105399, dated 11 / 18 / 2025, p. 10 / 100 / 76 details below with reference to examples thereof, as illustrated in the attached drawings, along which identical or similar elements, or elements with identical or similar functions, are indicated by the same reference numerals or by similar reference numerals. The embodiments described below with reference to the drawings are merely illustrative and are intended to explain, and not limit, the embodiments of this disclosure.

[0045] A washing machine typically includes an outer tub, an inner tub, an agitator, a drive mechanism, a drive unit, and a control unit. The agitator is usually mounted at the bottom of the inner tub. During washing, the agitator can rotate relative to the inner tub and drive the water flow in the inner tub to rotate, thus performing the wrinkling and cleaning of the clothes by agitating the water flow. However, because the agitator is mounted at the bottom of the inner tub, the agitation force of the agitator on the water flow gradually decreases from the bottom to an opening of the inner tub, and the drive capacity on the water flow also gradually decreases, resulting in uneven washing of the clothes. In view of this, some conventional agitators are provided with a four-inlet water spray structure.The water spray system can spray water into the inner tub to increase the intensity of the laundry wash at the upper end of the inner tub.

[0046] In the related technique, the water flow from an agitator rod that sprays water into four inlets on the cleaning apparatus is dispersed. The drive capacity of the agitator rod on the water flow is weak, resulting in a poor water spraying effect and uneven washing intensity for the laundry, which would decrease the washing quality and therefore lead to a poor user experience.

[0047] A stirring device 2 according to an embodiment Petition 870250105399, dated 11 / 18 / 2025, page 11 / 100 / 76 of the present disclosure is described below with reference to Figure 1 to Figure 12.

[0048] As illustrated in Figure 1 and Figure 6, the agitation device 2 according to the embodiment of the present disclosure may include a main body and an agitation housing 22. The main body may provide mounting locations for some components of the agitation device 2 and provide support and fixation for some components of the agitation device 2. The main body may be disposed at the bottom of the inner tank in the cleaning apparatus 1. In addition, the main body may be connected to a power component in the cleaning apparatus 1 to perform the operation of the main body. The agitation housing 22 is disposed on the main body. In addition, a circulation channel 23 is defined between the agitation housing 22 and the main body.The circulation channel 23 has a first inlet and a second inlet located on the lower surface of the main body. Furthermore, the first inlet is separated from the second inlet in a circumferential direction from the main body. When the cleaning apparatus 1 is in a washing stage, the washing water in the inner tank can enter the circulation channel 23 through the first and second inlets on the lower surface of the main body, respectively, and can flow out of the circulation channel 23 to implement water spraying from the agitation device 2 into the inner tank.

[0049] In the embodiments of the present disclosure, by providing the main body and the agitation housing 22 to define the circulation channel 23 between the agitation housing 22 and the main body, which projects the circulation channel 23 to have the first inlet and the second inlet located on the lower surface of the main body, the washing water in the inner tank can enter the circulation channel 23 from the first and second inlets on the lower surface of the main body, respectively, and can drain out of the circulation channel 23, so as to perform the spraying function of Petition 870250105399, dated 11 / 18 / 2025, page 12 / 100 / 76 water from agitation device 2. In the related technique, the water flow from the agitation rod to spray water into four inlets is dispersed. The drive capacity of the agitation rod in the water flow is weak, resulting in a poor water spraying effect. In the embodiments of the present disclosure, the circulation channel 23 has two inlets, namely, the first inlet and the second inlet, which are separated from each other in the circumferential direction of the main body. The two inlets can allow the washing water to enter the circulation channel 23 more intensely, which increases the force of the washing water flow from a bottom to an opening of the inner tub, thus improving the water spraying intensity of the agitation device 2. In addition, a more uniform washing of the laundry is achieved, which effectively increases the washing effect of the laundry by the cleaning apparatus 1.

[0050] Furthermore, in an exemplary embodiment of the present disclosure, the main body is connected to a motor disposed in the cleaning apparatus 1. The motor can drive the main body to rotate clockwise or counterclockwise in the inner tub. When the cleaning apparatus 1 is in the washing stage, the main body rotates counterclockwise, which causes the washing water inside the inner tub to gain an overall counterclockwise velocity. Then, the main body is switched to rotate clockwise. Due to inertia, the washing water in the circulation channel 23 still maintains a counterclockwise flow, which causes the washing water to move in the circulation channel 23 and finally be sprayed to a high position after overcoming gravity.Therefore, by relying on the main body to alternately rotate counterclockwise and clockwise in a cyclical manner, the water spraying function of agitation device 2 can be performed.

[0051] According to an embodiment of the present revelation, an angle of each of the first and second entries in relation to the center of Petition 870250105399, dated 11 / 18 / 2025, page 13 / 100 / 76 main body is α, where 45°<α<140°. In an exemplary embodiment of the present disclosure, the wash water enters the circulation channel 23 from the first inlet and the second inlet, respectively. By defining the angle between each of the first inlets and the second inlet and the center of the main body, a flow field of the wash water can be controlled to a pattern that is more conducive to concentrated flow in the circulation channel 23. By defining the angle between each of the first inlets and the second inlet and the center of the main body within the above range, an appropriate spacing distance is formed between the first inlet and the second inlet in the circumferential direction of the main body.Therefore, the concentrated entry of wash water into the circulation channel 23 through the first and second inlets is facilitated, which helps to further increase the flow force of the wash water in the circulation channel 23 and the flow rate of the wash water entering the circulation channel 23 through the first and second inlets. Furthermore, the water spraying effect of the agitation device 2 is enhanced, so as to achieve more uniform washing of the clothes by the wash water and thus improve the washing quality.

[0052] Furthermore, in an exemplary embodiment of the present disclosure, the angle between each of the first and second inlets and the center of the main body is set at 135°, so as to achieve an enhanced flow effect when the wash water enters the circulation channel 23, and a water spray effect further intensified by the agitation device 2.

[0053] As illustrated in Figure 7, Figure 4 and Figure 9, according to one embodiment of the present disclosure, the agitation device 2 may additionally include flow guide ribs 24. In this embodiment, the flow guide ribs 24 may be arranged such that the flow guide ribs 24 are present only in the main body and Petition 870250105399, dated 11 / 18 / 2025, p. 14 / 100 / 76 are not present in the agitation housing 22. In this embodiment, the flow guide ribs 24 can also be arranged so that the flow guide ribs 24 are positioned only in the agitation housing 22 and are not arranged in the main body. In this embodiment, the flow guide ribs 24 can also be arranged so that the flow guide ribs 24 are positioned both in the main body and in the agitation housing 22. At least part of the flow guide ribs 24 is received in the circulation channel 23 and divides the circulation channel 23 into a plurality of subcirculation channels. In this way, the wash water can enter through the first inlet or the second inlet along the plurality of subcirculation channels, respectively.

[0054] By providing flow guide ribs 24, on the one hand, flow guidance can be provided for the wash water in such a way that the wash water can flow along a predetermined path to allow the agitation device 2 to spray water into the inner tank. On the other hand, by arranging the flow guide ribs 24 in the main body and / or agitation housing 22, at least part of the flow guide ribs 24 can divide the circulation channel 23 into a plurality of circulation subchannels, which eliminates the potential energy of entry when the wash water flows into the circulation subchannel through the first or second inlet. In this way, a flow field pattern of the wash water at the first and second inlets is better, and the wash water can be uniformly distributed in each subcirculation channel.Therefore, the smoothness of the wash water flowing into the first and second inlets can be improved, and thus the volume of wash water inlet can be increased, which optimizes the water spraying performance of agitation device 2.

[0055] According to one embodiment of the present disclosure, the main body includes a base 211 and a disc portion 212. In this Petition 870250105399, dated 11 / 18 / 2025, page 15 / 100 / 76. In this embodiment, the base 211 can be configured to be connected to the power supply component in the cleaning apparatus 1, in order to enable the assembly, fixing and operation of the main body. In this embodiment, the disc portion 212 is disposed in at least part of the outer periphery of the base 211. Furthermore, the disc portion 212 extends outward from the base 211. A surface of the disc portion 212 is separated from an inner surface of the agitation housing 22. At least part of the flow guide ribs 24 is situated between a lateral surface of the disc portion 212 and the inner surface of the agitation housing 22. The first inlet and the second inlet are formed between two lateral edges of the disc portion 212 in the circumferential direction and the agitation housing 22.By providing the base 211 and the disc portion 212, the base 211 can be configured to be connected to the power component in the cleaning apparatus 1, so as to perform the assembly and fixing of the base 211 and the disc portion 212 in the cleaning apparatus 1, as well as ensuring the normal operation of the base 211 and the disc portion 212. Furthermore, as illustrated in Figure 10, since the disc portion 212 has a predetermined inclination, and the first and second inlets are formed between two lateral edges of the disc portion 212 in the circumferential direction and the agitation housing 22, when the wash water enters the first or second inlet, the inclination of the disc portion 212 promotes the axial flow of the wash water gradually towards the inner tank. Therefore, a favorable flow direction of the wash water can be guaranteed, and thus the water spraying performance of the agitation device 2 can be improved.

[0056] According to one embodiment of the present disclosure, the main body additionally includes a column segment 213. In this embodiment, the column segment 213 is disposed on the base 211. Furthermore, the column segment 213 extends in the axial direction from the base 211. Petition 870250105399, dated 11 / 18 / 2025, page 16 / 100 / 76 It should be understood that column segment 213 also extends in the axial direction of disc portion 212, in the opposite direction of disc portion 212. At least part of the agitator housing 22 is fitted onto the outer periphery of column segment 213. Furthermore, the inner surface of the agitator housing 22 is separated from the outer surface of column segment 213. An outlet of the circulation channel 23 is formed between a free end of column segment 213 and the agitator housing 22. By providing column segment 213 on base 211 and designing column segment 213 to extend in the axial direction of base 211, and forming the outlet of the circulation channel 23 between the free end of column segment 213 and the agitator housing 22, when cleaning apparatus 1 washes clothes, the washing water can enter the circulation channel 23 from the first inlet and the second inlet, respectively.Furthermore, after sequentially passing through disc portion 212 and column segment 213, the wash water can be sprayed out of the outlet located at the free end of column segment 213 to wash the clothes. Since disc portion 212 is disposed at least partly on the outer periphery of base 211 and extends outward from base 211, and column segment 213 is disposed over base 211 and projects in the axial direction of base 211, the wash water can flow from the two lateral edges of disc portion 212, in the circumferential direction, towards the center of disc portion 212, and then flow from disc portion 212 towards column segment 213, and flows in the axial direction of column segment 213.Column segment 213 diverts the wash water, allowing the wash water entering the circulation channel 23 in the circumferential direction of the disc portion 212 to be sprayed out by the outlet located at the free end of column segment 213, which is positioned in the axial direction of the base 211. Finally, under the action of gravity, the wash water can fall into the inner tub to wash the clothes, which intensifies the washing effect of the cleaning device 1 on the clothes. Petition 870250105399, dated 11 / 18 / 2025, page 17 / 100 / 76

[0057] According to one embodiment of the present disclosure, the flow guide ribs 24 are formed on a surface of the disc portion 212. The flow guide ribs 24 extend from the first inlet and / or the second inlet to an edge of the disc portion 212 near the column segment 213. In an exemplary embodiment of the present disclosure, at least part of the flow guide ribs 24 is positioned between the surface of the disc portion 212 and the inner surface of the agitation housing 22, in order to guide the wash water flowing over the surface of the disc portion 212. One end of the flow guide rib 24 on the surface of the disc portion 212 is located on one side and / or both lateral edges of the disc portion 212 in the circumferential direction, and the other end of the flow guide rib 24 on the surface of the disc portion 212 extends to the edge of disk portion 212 near column segment 213.Since the flow guide rib 24 can provide flow direction for the wash water, by designing the flow guide rib 24 to extend from the first inlet and / or the second inlet to the edge of the disc portion 212 near the column segment 213, on the one hand, it is ensured that when the wash water enters the first or second inlet, the wash water can flow from the edge of the disc portion 212 in a circumferential direction towards the edge of the disc portion 212 near the column segment 213, which ensures that the wash water can enter the circulation channel 23 on the outer surface of the column segment 213 along a predetermined path, in addition to further enhancing the precise control of the water jet direction by the agitator device 2.On the other hand, by designing the flow guide rib 24 to extend from the first inlet and / or the second inlet to the edge of the disc portion 212 near the column segment 213, it is also ensured that the wash water can flow along the plurality of circulation subchannels, respectively, after entering the first inlet or. Petition 870250105399, dated 11 / 18 / 2025, page 18 / 100 / 76 in the second entry. In this way, the wash water can always present a good flow field pattern on the surface of the disc portion 212, which increases the flow force of the wash water from the surface of the disc portion 212 to the outer surface of the column segment 213. Therefore, the spray intensity of the wash water from the outlet at the free end of the column segment 213 is increased.

[0058] As illustrated in Figures 9 to 12, according to one embodiment of the present disclosure, the plurality of flow guide ribs 24 is arranged, respectively, on both sides of the disc portion 212 in the circumferential direction. The plurality of flow guide ribs 24 can provide flow guidance and flow diversion for the wash water. The plurality of flow guide ribs 24 includes a first flow guide rib 241 and a second flow guide rib 242. In this embodiment, one end of the first flow guide rib 241 is connected to the disc portion 212 at the outer edge of the first or second inlet orifice, and the other end of the first flow guide rib 241 extends to the radial inner edge of the disc portion 212 and is connected to the speaker segment 213.In this embodiment, one end of the second flow guide rib 242 is connected to the disc portion 212 at the inner edge of the first or second inlet, and the other end of the second flow guide rib 242 extends to the radial inner edge of the disc portion 212 and is connected to the column segment 213. The first flow guide rib 241 is separated from the second flow guide rib 242 in the circumferential direction of the disc portion 212. By providing the first flow guide rib 241 and the second flow guide rib 242, i.e., by spacing the first flow guide rib 241 and the second flow guide rib 242 from each other in the circumferential direction of the disc portion 212, at least part of the first circulation channel 23 or the second circulation channel 23 can be defined between a. Petition 870250105399, dated 11 / 18 / 2025, page 19 / 100 / 76 surface of the disc portion 212 and the inner surface of the agitation housing 22, jointly by the first flow guide rib 241 and the second flow guide rib 242. Each of the first circulation channels 23 and the second circulation channel 23 may have a plurality of subcirculation channels. The first circulation channel 23 and the second circulation channel 23 correspond to the first inlet and the second inlet, respectively. Therefore, the washing water can flow into the respective first circulation channel 23 and second circulation channel 23 through the first inlet and second inlet, and then flow out of a first outlet of the first circulation channel 23 and a second outlet of the second circulation channel 23 at the free end of the column segment 213. As a result, a good water spraying effect is obtained from the agitation device 2.

[0059] According to one embodiment of the present disclosure, the flow guide ribs 24 additionally include a third flow guide rib 243. The third flow guide rib 243 is disposed between the first flow guide rib 241 and the second flow guide rib 242. The third flow guide rib 243 is separated from the first flow guide rib 241 and the second flow guide rib 242, respectively, in the circumferential direction of the disc portion 212. In an exemplary embodiment of the present disclosure, one end of the third flow guide rib 243 is connected to the disc portion 212 at the outer edge of the first or second inlet, and the other end of the third flow guide rib 243 extends to the radial inner edge of the disc portion 212.The third flow guide rib 243 is separated from the first flow guide rib 241 and the second flow guide rib 242 by a predetermined distance in the circumferential direction of the disc portion 212. By providing the third flow guide rib 243, the flow guiding effect on the wash water can be enhanced. Furthermore, the... Petition 870250105399, dated 11 / 18 / 2025, page 20 / 100 / 76 The first circulation channel 23 or the second circulation channel 23 can be divided into different subcirculation channels through the third flow guide rib 243, which can cause the wash water to be diverted from the first inlet or the second inlet to a subcirculation channel in the first circulation channel 23 or a subcirculation channel of the second circulation channel 23. Therefore, the wash water can always present a good flow field pattern when entering the first inlet orifice and the second inlet orifice, as well as the surface of the disc portion 212. Furthermore, it can be ensured that the wash water has sufficient ejection force when flowing out of the free end outlet of the column segment 213.

[0060] Furthermore, in some exemplary embodiments of the present disclosure, one end of each of the first flow guide rib 241, second flow guide rib 242 and third flow guide rib 243 is bent from an inner edge of the first inlet or an inner edge of the second inlet toward the radial inner edge of the disc portion 212, in the same direction along the circumferential direction of the disc portion 212, to allow wash water to enter the first circulation channel 23 or the second circulation channel 23 from the first inlet or the second inlet in the circumferential direction of the disc portion 212. Therefore, a greater amount of wash water entering the first circulation channel 23 and the second circulation channel 23 can be increased.

[0061] According to one embodiment of the present disclosure, a plurality of third flow guide ribs 243 is provided. Furthermore, the plurality of third flow guide ribs 243 is arranged at intervals in the circumferential direction of the disc portion 212. In an exemplary embodiment of the present disclosure, each of the several third guide ribs 243 is arranged between the first flow guide rib 241 and the Petition 870250105399, dated 11 / 18 / 2025, p. 21 / 100 / 76 second flow guide rib 242. One end of each of the several third guide ribs 243 is connected to the disc portion 212 at the inner edge of the first inlet or at the inner edge of the second inlet, respectively, and the other end of the third guide rib 243 extends towards the inner radial edge of the disc portion 212. By providing a plurality of third guide ribs 243, a flow guiding effect of the third flow guide rib 243 on the wash water is further enhanced. In addition, the first circulation channel 23 and the second circulation channel 23 can be separated into a plurality of subcirculation channels, respectively. As a result, it is further ensured that the wash water can always present a good flow field pattern when entering the first inlet hole and the second inlet hole, as well as on the surface of the disc portion 212.Furthermore, it can be ensured that the wash water has sufficient ejection force as it flows out of the free end outlet of column segment 213.

[0062] According to one embodiment of the present disclosure, a fourth flow guide rib 244 and a fifth flow guide rib 245, extending in the axial direction of column segment 213, are formed on the outer surface of column segment 213. The fourth flow guide rib 244 is constructed as a plurality of fourth flow guide ribs 244 in one-to-one correspondence with the first flow guide ribs 241. Furthermore, one end of each of the fourth flow guide ribs 244 is connected to the first flow guide rib 241, and the other end of the fourth flow guide rib 244 extends to the free end of column segment 213. The fifth flow guide ribs 245 are constructed as a plurality of fifth flow guide ribs. 245 corresponding one to one with the second flow guide ribs 242.In addition, one end of each of the fifth flow guide ribs 245 is connected to the second. Petition 870250105399, dated 11 / 18 / 2025, p. 22 / 100 / 76 flow guide rib 242, and the other end of the fifth flow guide rib 245 extends to the free end of the column segment 213. The fourth flow guide rib 244 is separated from the fifth flow guide rib 245 in the circumferential direction of the column segment 213. By providing the fourth flow guide rib 244 and the fifth flow guide rib 245, and connecting the end of the fourth flow guide rib 244 to the first flow guide rib 241 and the end of the fifth flow guide rib 245 to the second flow guide rib 242, another part of the first channel or second channel is defined by the fourth flow guide rib and the fifth flow guide rib, the outer surface of the column segment 213, and the agitation housing. 22 together.Therefore, the entire first channel or the entire second channel is defined by the first flow guide rib 241, the second flow guide rib 242, the third flow guide rib 243, the fourth flow guide rib 244, and the fifth flow guide rib 245, as well as by the surface of the disc portion 212, the outer surface of the column segment 213, and the agitation housing 22. As a result, the washing water can flow smoothly along at least part of the first circulation channel 23 or the second circulation channel 23 in the disc portion 212 to another part of the first circulation channel 23 or the second circulation channel 23 on the outer surface of the column segment 213, and finally sprayed through the first outlet or the second outlet orifice, thus completing the spraying and washing of the clothes by the agitation device 2.

[0063] In some embodiments of the present disclosure, an extension direction of the fourth flow guide rib 244 and an extension direction of the fifth flow guide rib 245 are parallel to a geometric axis of the column segment 213, to enable axial flow of wash water along the column segment 213 in the first channel or in the second channel in Petition 870250105399, dated 11 / 18 / 2025, page 23 / 100 / 76 external surface of column segment 213. Therefore, it is beneficial to increase the water spray intensity of the agitation device 2 and expand the water spray coverage of the inner tub of the agitation device 2. In addition, the cleaning effect of the cleaning device 1 on the clothes can be improved.

[0064] According to one embodiment of the present disclosure, a stirring rib 221 is formed on the outer surface of the stirring housing 22. The stirring rib 221 projects in a radial direction. By providing the stirring rib 221, when the drive unit in the cleaning apparatus 1 drives the stirring housing 22 to rotate, the stirring rib 221 rotates together with the stirring housing 22, which increases the force of the washing water flow in the inner tub and intensifies the washing effect on the clothes. In addition, the stirring rib 221 can also increase the frictional force between the stirring housing 22 and the clothes, which further enhances the washing effect of the stirring device 2 on the clothes.

[0065] Furthermore, in some embodiments of the present disclosure, the agitation rib 221 is constituted by a plurality of agitation ribs 221 arranged at intervals in the circumferential direction of the agitation housing 22, in order to further optimize the washing effect of the agitation device 2 on the clothes.

[0066] In other embodiments of the present disclosure, the agitation housing 22 also has an agitation groove 222, recessed towards the column segment 213 and formed on the outer surface of the agitation housing 22. The agitation groove 222 can increase the frictional force between the outer surface of the agitation housing 22 and the clothes, in addition to further enhancing the washing effect of the agitation device 2 on the clothes.

[0067] Cleaning device 1, according to the modalities of Petition 870250105399, dated 11 / 18 / 2025, page 24 / 100 / 76, the present disclosure is briefly described below.

[0068] Since the cleaning apparatus 1, according to the embodiments of the present disclosure, includes the agitation device 2 according to any of the embodiments above, the circulation channel 23 is formed between the agitation housing 22 and the main body of the agitation device 2 in the cleaning apparatus 1. The washing water can enter the circulation channel 23 through the first inlet and the second inlet to perform the water spraying function of the agitation device 2, which results in the good water spraying effect of the agitation device 2. Therefore, the washing effect of the cleaning apparatus 1 on the clothes can be improved, leading to a good user experience.

[0069] In summary, the agitation device 2, according to the embodiments of the present disclosure, includes a main body, an agitation housing 22, and flow guide ribs 24. The agitation housing 22 is disposed on the main body. The circulation channel 23 is defined between the agitation housing 22 and the main body. The circulation channel 23 has a first inlet and a second inlet that are located on a lower surface of the main body. The first inlet is separated from the second inlet in a circumferential direction from the main body. The flow guide ribs 24 are disposed on the main body and / or the agitation housing. At least part of the flow guide ribs 24 are received in the circulation channel 23. Furthermore, the circulation channel 23 is divided into a plurality of subcirculation channels by at least part of the flow guide ribs 24.The main body includes a column segment disposed over base 211 and extending in the axial direction of base 211.

[0070] At least part of the agitation housing 22 is coated over the column segment 213 and separated from an outer surface of the column segment 213. An outlet communicating with the channel Petition 870250105399, dated 11 / 18 / 2025, page 25 / 100 / 76. Circulation channel 23 is formed between a free end of column segment 213 and the agitation housing 22. When the cleaning apparatus 1 is in the washing phase, the wash water can enter the circulation channel 23 from the first and second inlets on the lower surface of the main body, respectively, and finally exit through the outlet of the circulation channel 23 at the free end of column segment 213, which allows the agitation device 2 to have good water spraying. As two inlets, namely the first inlet and the second inlet, are arranged in the main body, the two inlets can allow the wash water to enter the circulation channel 23 in a more concentrated manner, which increases the flow force of the wash water along the bottom to the opening of the inner tank and improves the water spraying intensity of the agitation device 2.Furthermore, a more uniform wash is performed on the clothes, which effectively intensifies the washing effect of the cleaning appliance 1.

[0071] A washing machine typically includes an outer tub, an inner tub, an agitator, a drive mechanism, a drive unit, and a control unit. The agitator is usually mounted at the bottom of the inner tub. During washing, the agitator can rotate relative to the inner tub and drive the water flow in the inner tub to rotate, thus agitating and cleaning the clothes by agitating the water flow. However, because the agitator is mounted at the bottom of the inner tub, the agitation force of the agitator on the water flow gradually decreases from the bottom to the opening of the tub, and the drive capacity on the water flow also gradually decreases, resulting in uneven washing of the clothes. In view of this, some existing agitators are provided with a water spray structure.The water spray system can spray water into the inner tub to increase the washing intensity of the clothes at the upper end of the tub. Petition 870250105399, dated 11 / 18 / 2025, page 26 / 100 / 76 internal. A water sprinkler structure circulation channel generally has an inlet segment as a horizontal segment and an outlet segment as a vertical segment.

[0072] In the related technique, in the water spray structure of the agitator rod of the cleaning apparatus, a circulation channel close to a water inlet segment is the horizontal segment, which leads to a steep inclination of a transition segment circulation channel between a horizontal segment circulation channel and a vertical segment circulation channel. In this way, the resistance to the flow of water in the circulation channel is increased, which results in a poor water spray effect. As a result, an uneven washing intensity for the laundry may occur, which reduces the washing quality and thus results in a poor user experience.

[0073] A stirring assembly 2 according to an embodiment of the present disclosure is described below with reference to Figure 1, and Figure 13 to Figure 20.

[0074] As illustrated in Figure 1 and Figure 17, the agitation assembly 2, according to the embodiments of the present disclosure, includes a main body and an agitation housing 22. The main body can provide mounting locations for some components in the agitation assembly 2 and provide support and fixation for some components in the agitation assembly 2. The main body can be mounted on the lower wall of the inner tub of the cleaning apparatus 1. In addition, the main body can be connected to the power component in the cleaning apparatus 1 to perform the operation of the main body. The main body has a first surface and a central geometric axis extending in a height direction. An agitation housing 22 is disposed in the main body and has a second surface. At least part of the second surface of the agitation housing 22 is separated from the first surface to define the channel of Petition 870250105399, dated 11 / 18 / 2025, page 27 / 100 / 76 circulation 23. When the cleaning apparatus 1 is in the washing phase, the washing water in the inner tank can flow into the circulation channel 23 and exit the circulation channel 23 to allow the agitation assembly 2 to spray water into the inner tank. The second surface includes a first annular surface 225 formed by extending an outer edge of the agitation housing 22 away from the geometric axis towards the geometric axis. The first annular surface 225 has a width of d1, and the width from the outer edge of the agitation housing 22 to the central geometric axis is d2, where d2 / d1>18. The first annular surface is inclined away from the first surface in a direction that radially approaches the central geometric axis. Therefore, at least part of the circulation channel 23 is defined by the first annular surface 225, and the first surface has a predetermined slope.

[0075] In embodiments of the present disclosure, when providing the main body and the agitation housing 22, at least a portion of the second surface of the agitation housing 22 is separated from the first surface of the main body to define the circulation channel 23, which allows the wash water in the inner tank to flow into the circulation channel 23 and exit the circulation channel 23, so as to perform the water spraying function of the agitation assembly 2. In embodiments of the present disclosure, the second surface of the agitation housing 22 includes the first annular surface 225. Furthermore, the first annular surface 225 is inclined away from the first surface in a direction that approaches radially from the central geometric axis. Therefore, at least the portion of the circulation channel 23 defined by the first annular surface 225 and the first surface has a predetermined inclination.The slope of the entire circulation channel 23 can be determined by the ratio between the width of the first annular surface 225 and the width from the outer edge of the agitation housing 22 to the central geometric axis. Therefore, by defining the ratio between the width d1 of the first... Petition 870250105399, dated 11 / 18 / 2025, page 28 / 100 / 76 annular surface 225 and the width d2 from the outer edge of the agitation housing 22 to the geometric axis so as to satisfy d2 / d1>18, the uniformity of the overall slope of the circulation channel 23 between the first surface and the second surface can be improved, the flow force of the wash water in the circulation channel 23 can be increased, and the water spray intensity of the agitation assembly 2 can be intensified. In the related technique, the flow channel of the transition segment between the circulation channel of the horizontal segment and the circulation channel of the vertical segment of the water spray structure has a steep slope, which would increase the resistance to water flow in the circulation channel and result in a deficient water spray effect.In the embodiments of the present disclosure, for the agitation assembly 2, under the condition that the agitation housing 22 has the same size, the first annular surface 225 is arranged in an inclined manner, and the ratio of the width of the first annular surface 225 to the outer edge of the agitation housing 22 from the geometric axis is smaller. Therefore, the inclination of other partial surfaces on the second surface, located on one side of the first annular surface 225 close to the geometric axis of the main body, can be reduced, which improves the overall uniformity of the inclination of the circulation channel 23 between the first surface and the second surface.Furthermore, the inclined arrangement of the first annular surface 225 also reduces the slope difference between two adjacent segments of the circulation channel 23, which are formed respectively between the first annular surface 225 and the first surface, and between the other partial surfaces on the second surface and the first surface. Therefore, the flow force of the washing water can be increased, which increases the water spray intensity of the agitation assembly 2. Therefore, a more uniform washing of the clothes is achieved, which effectively intensifies the washing effect of the cleaning apparatus 1 on the clothes. Petition 870250105399, dated 11 / 18 / 2025, page 29 / 100 / 76

[0076] Furthermore, in an exemplary embodiment of the present disclosure, the main body is connected to the motor disposed in the cleaning apparatus 1. The motor can drive the main body to rotate clockwise or counterclockwise in the inner tub. When the cleaning apparatus 1 is in the washing stage, the main body rotates counterclockwise, which causes the washing water inside the inner tub to gain an overall counterclockwise velocity. Then, the main body is switched to rotate clockwise. Due to inertia, the washing water in the circulation channel 23 still maintains the counterclockwise flow, which causes the washing water to move in the circulation channel 23 and finally be sprayed out of the high position after overcoming gravity.Therefore, by relying on the main body to alternately rotate counterclockwise and clockwise in a cyclical manner, the water spraying function of agitation assembly 2 can be performed.

[0077] According to one embodiment of the present disclosure, d1<5 mm. As the first annular surface 225 is formed by extending the outer edge of the agitation housing 22 away from the geometric axis towards the geometric axis, on the one hand, by setting the width of the first annular surface 225 within the range mentioned above, the first annular surface 225 has an adequate width. In this way, when the cleaning apparatus 1 is in the washing phase, the washing water in the inner tank can easily enter the circulation channel 23 between the first annular surface 225 and the first surface of the main body, which can be more beneficial to increase the amount of water spraying and the intensity of water spraying of the agitation assembly 2.On the other hand, by defining the width of the first annular surface 225 within the mentioned range, it can be ensured that the ratio of the width of the first annular surface 225 to the outer edge of the agitation housing 22 from the geometric axis is within a favorable range. Petition 870250105399, dated 11 / 18 / 2025, page 30 / 100 / 76 to improve the uniformity of the overall slope of the circulation channel 23. Therefore, the flow force of the washing water in the circulation channel 23 is greater, resulting in more uniform washing of the clothes by the washing water. Therefore, the washing quality of the cleaning device 1 on the clothes is improved.

[0078] According to one embodiment of the present disclosure, the agitation housing 22 includes a peripheral wall portion 223 and a conical portion 224. In this embodiment, the peripheral wall portion 223 is constructed in an annular shape. The peripheral wall portion is arranged around an outer peripheral edge of the main body and extends axially away from the main body. One axial end of the peripheral wall portion is connected to at least part of the outer peripheral edge of the main body. In this embodiment, the conical portion 224 has an outer edge connected to another axial end of the peripheral wall portion. The conical portion 224 extends obliquely from the main body towards the center of the peripheral wall portion. The second surface is formed on a surface of the conical portion 224 facing the main body.By providing the peripheral wall portion 223 and the conical portion 224, the second surface on one side of the conical portion 224 facing the main body is inclined away from the main body towards the center of the peripheral wall portion 223. Therefore, the circulation channel 23 extending obliquely from the main body towards the center of the peripheral wall portion 223 is formed between the peripheral wall portion 223, the conical portion 224, and the main body. Furthermore, the wash water can flow along the obliquely extending circulation channel to perform the water spraying function of the agitation assembly 2.

[0079] According to an embodiment of the present disclosure, the main body includes a base 211, a disk portion 212 and a segment Petition 870250105399, dated 11 / 18 / 2025, page 31 / 100 / 76 of column 213. In this mode, base 211 can be configured to be connected to the power supply component in cleaning device 1, in order to enable the assembly, fixing and operation of the main body. In this embodiment, the disc portion 212 is disposed over at least part of the outer periphery of the base 211. Furthermore, the disc portion 212 extends outward from the base 211. The first surface is formed on the disc portion 212. A first inlet and a second inlet of the circulation channel 23 are formed between two lateral edges of the disc portion 212 in the circumferential direction and the second surface of the agitation housing 22. In this embodiment, the column segment 213 is disposed over the base 211 and extends in the axial direction of the base 211. It should be understood that the column segment 213 also extends away from the disc portion 212 in the axial direction of the disc portion 212.At least part of the agitation housing 22 is fitted onto the column segment 213. Furthermore, the agitation housing 22 is separated from the outer surface of the column segment 213. The outlet of the circulation channel 23 is formed between the free end of the column segment 213 and the agitation housing 22.

[0080] By arranging the base 211 so that the base 211 is connected to the power supply component in the cleaning apparatus 1, the mounting and fixing of the base 211, the disc portion 212 and the column segment 213 in the cleaning apparatus 1 are carried out, thus ensuring the normal operation of the base 211, the disc portion 212 and the column segment 213. The disc portion 212 is arranged so that the first surface is formed on the disc portion 212 and is separated from the second surface.The second surface is inclined away from the main body towards the center of the peripheral wall portion, and the disc portion 212 has the first and second inlets between the two lateral edges in the circumferential direction of the disc portion 212 and the agitation housing 22. As a result, when the wash water enters the first or second orifice. Petition 870250105399, dated 11 / 18 / 2025, page 32 / 100 / 76 of the inlet, the axial flow of the washing water towards the inner tub is gradually achieved by an inclination of the disc portion 212, so as to ensure the proper direction of the washing water flow and enhance the water spraying performance of the agitator assembly 2. Since the column segment 213 is arranged on the base 211 and extends in the axial direction of the base 211, and the outlet of the circulation channel 23 is formed between the free end of the column segment 213 and the agitator housing 22, respectively, when the cleaning apparatus 1 performs the washing of clothes, the washing water can enter the circulation channel 23 from the first inlet and the second inlet, respectively.Furthermore, after passing sequentially through disc portion 212 and column segment 213, the wash water can be sprayed from the outlet orifice located at the free end of column segment 213 to wash the clothes. As disc portion 212 is disposed on at least part of the outer periphery of base 211 and extends outward from base 211, and column segment 213 is disposed on base 211 and projects in the axial direction of base 211, the wash water flows from two lateral edges of disc portion 212, in the circumferential direction towards the center of disc portion 212, and then flows from disc portion 212 towards column segment 213 along the axial direction of column segment 213.Column segment 213 diverts the wash water, allowing the wash water entering the circulation channel 23 in the circumferential direction of the disc portion 212 to be sprayed from the outlet located at the free end of column segment 213, which is positioned in the axial direction of the base 211. Finally, under the action of gravity, the wash water falls into the inner tub to wash the clothes, which intensifies the washing effect of the cleaning apparatus 1 on the clothes.

[0081] According to one embodiment of the present disclosure, two lateral edges of disk portion 212, in the circumferential direction, exhibit Petition 870250105399, dated 11 / 18 / 2025, page 33 / 100 / 76 arc shape and project outwards from the main body. Since the first and second inlets of the circulation channel 23 are formed between the two lateral edges of the disc portion 212 in the circumferential direction and the second surface of the agitation housing 22, by configuring the two lateral edges of the disc portion 212 in the circumferential direction in an arc shape and causing the two lateral edges of the disc portion 212 in the circumferential direction to project away from the main body, it is possible to increase the washing water flow area of ​​the first inlet and the washing water flow area of ​​the second inlet, as well as increasing the water inlet volume of the circulation channel 23. Therefore, the water spray volume of the agitation assembly 2 can be increased, which is conducive to improving the washing effect of the cleaning apparatus 1.

[0082] According to one embodiment of the present disclosure, a segment splitting rib of column 2131 is formed on an outer circumferential surface of column segment 213. Furthermore, the segment splitting rib of column 2131 is formed by a plurality of segment splitting ribs of column 2131 arranged at intervals in the circumferential direction of column segment 213, and the circulation channel 23 is divided into a plurality of subcirculation channels by the plurality of segment splitting ribs of column 2131. Each of the plurality of subcirculation channels has a width of W, and a distance between the outer circumferential surface of column segment 213 and an inner wall surface of the agitation housing 22 is L, wherein 2 <W / L<6.By arranging the plurality of dividing ribs of column segment 2131 at intervals in the circumferential direction of column segment 213, circulation channel 23 is divided into a plurality of subcirculation channels. In this way, after entering the first or second inlet, the wash water can flow along the plurality of subcirculation channels, respectively, in such a way that the water... Petition 870250105399, dated 11 / 18 / 2025, page 34 / 100 / 76. The washing process can always have a good flow field pattern on the outer circumferential surface of column segment 213. Therefore, the flow force of the washing water on the outer circumferential surface of column segment 213 and the spray intensity of the washing water from the free end outlet of column segment 213 can be increased. By defining a ratio between the width of the subcirculation channel in the circumferential direction and the distance between the outer circumferential surface of column segment 213 and the inner wall surface of the agitation housing 22 within the mentioned range, each subcirculation channel acquires a shape and size more suitable for optimizing the flow field pattern of the washing water. Therefore, the flow force of the washing water is increased, which further increases the spray intensity of the agitation assembly 2.

[0083] Furthermore, in an exemplary embodiment of the present disclosure, the width W of the subcirculation channel in the circumferential direction and the distance L between the outer circumferential surface of the column segment 213 and the inner wall surface of the agitation housing 22 satisfy W / L=5.2. In this way, a better flow field pattern of the washing water is achieved in each subcirculation channel, which further optimizes the water spraying performance of the agitation assembly 2.

[0084] According to one embodiment of the present disclosure, a plurality of dividing ribs of disc portion 24 is arranged, respectively, on both sides of disc portion 212 in the circumferential direction. Each of the several dividing ribs of disc portion 24 includes a first dividing rib of disc portion 241 and a second dividing rib of disc portion 242. In this embodiment, one end of the first dividing rib of disc portion 241 is connected to disc portion 212 at the inner edge of the first entry or the second entry, and the other end of the first dividing rib of the Petition 870250105399, dated 11 / 18 / 2025, page 35 / 100 / 76 disc portion 241 extends to the radial inner edge of disc portion 212 and is connected to column segment 213. In this embodiment, one end of the second split rib of disc portion 242 is connected to disc portion 212 at the inner edge of the first or second entry, and the other end of the second split rib of disc portion 242 extends to the radial inner edge of disc portion 212 and is connected to column segment 213. The first split rib portion of disc 241 is separated from the second split rib portion of disc 242 in the circumferential direction of disc portion 212.By allowing the first split rib of disc portion 241 to be separated from the second split rib of disc portion 242 in the circumferential direction of disc portion 212, the first split rib of disc portion 241 and the second split rib of disc portion 242 can form, together with the surface of disc portion 212 and the surface of the inner wall of the agitation housing 22, the circulation channel 23. The circulation channel 23 can have a plurality of subcirculation channels. In this way, the wash water can flow into the plurality of subcirculation channels from the first inlet and the second inlet, respectively, and then flow out through the outlet at the free end of the column segment 213.

[0085] According to one embodiment of the present disclosure, the dividing rib of disc portion 24 additionally includes a third dividing rib of disc portion 243. The third dividing rib of disc portion 243 is disposed between the first dividing rib of disc portion 241 and the second dividing rib of disc portion 242. Furthermore, the third dividing rib of disc portion 243 is separated from the first dividing rib of disc portion 241 and the second dividing rib of disc portion 242, respectively, in the circumferential direction of disc portion 212. Petition 870250105399, dated 11 / 18 / 2025, p. 36 / 100 / 76

[0086] In an exemplary embodiment of the present disclosure, one end of the third split rib of disc portion 243 is connected to disc portion 212 at the outer edge of the first or second inlet, and the other end of the third split rib of disc portion 243 extends to the inner radial edge of disc portion 212. The third split rib of disc portion 243 is separated from the first split rib of disc portion 241 and the second split rib of disc portion 242 by a predetermined distance in the circumferential direction of disc portion 212. By providing the split rib of the third disc portion 243, the flow-directing effect on the wash water can be enhanced.Furthermore, the circulation channel 23 can be divided into different circulation subchannels by means of the dividing rib of the third disc portion 243, which can cause the wash water to be diverted from the first inlet or the second inlet to each circulation subchannel. Therefore, the wash water can always present a good flow field pattern when entering the first inlet orifice and the second inlet orifice, as well as on the surface of the disc portion 212. In addition, it can be ensured that the wash water has sufficient ejection force when flowing out of the free end outlet of the column segment 213.

[0087] Furthermore, in some embodiments of the present disclosure, the split rib end of the first disc portion 241, the split rib end of the second disc portion 242, and the split rib end of the third disc portion 243 curve from the inner edge of the first or second inlet, in the same circumferential direction as the disc portion 212 towards the radial inner edge of the disc portion 212, respectively, which allows the wash water to enter the circulation channel 23 from the first or second inlet in the circumferential direction of the disc portion 212. Therefore, Petition 870250105399, dated 11 / 18 / 2025, page 37 / 100 / 76 a greater quantity of wash water entering the circulation channel 23 can be facilitated.

[0088] In other embodiments of the present disclosure, the agitation housing 22 has an agitation rib 221 formed on the outer surface of the agitation housing 22. The agitation rib 221 projects in the radial direction. By providing the agitation rib 221, when the drive unit in the cleaning apparatus 1 drives the agitation housing 22 to rotate, the agitation rib 221 rotates together with the agitation housing 22, which increases the force of the wash water flow in the inner tub and intensifies the washing effect on the clothes. In addition, the agitation rib 221 can also increase the frictional force between the agitation housing 22 and the clothes, which further enhances the washing effect of the agitation assembly 2 on the clothes.

[0089] In some other embodiments of the present disclosure, the agitation housing 22 also features an agitation groove 222 that is recessed toward the column segment 213 formed on the outer surface of the agitation housing 22. The agitation groove 222 can increase the frictional force between the outer surface of the agitation housing 22 and the clothes, as well as further enhancing the washing effect of the agitation assembly 2 on the clothes.

[0090] A cleaning apparatus 1 according to the embodiments of the present disclosure is briefly described below.

[0091] As the cleaning apparatus 1, according to the embodiments of the present disclosure, includes the agitator assembly 2 in any of the embodiments above, the circulation channel 23 is formed between the agitator housing 22 and the main body of the agitator assembly 2 in the cleaning apparatus 1. The washing water can enter the circulation channel 23 through the first inlet and the second inlet to perform the water spraying function of the agitator assembly 2, resulting in the good effect of Petition 870250105399, dated 11 / 18 / 2025, page 38 / 100 / 76 water spray from agitation unit 2. Therefore, the washing effect of cleaning device 1 on the clothes can be improved, leading to a good user experience.

[0092] In summary, the agitation assembly 2, according to the embodiments of the present disclosure, includes the main body and the agitation housing 22. The main body has a first surface and a central geometric axis extending in a height direction. An agitation housing is disposed on the main body and has a second surface. At least part of the second surface is separated from the first surface to define the circulation channel 23. The second surface includes a first annular surface 225 formed by extending an outer edge of the agitation housing 22 away from the geometric axis towards the geometric axis. The first annular surface 225 is inclined away from the first surface in a direction radially approaching the central geometric axis.The ratio between the width d1 of the first annular surface 225 and the width d2 from the outer edge of the agitation housing 22 to the central geometric axis is defined so as to satisfy d2 / d1>18. The main body includes the base 211, the disc portion 212, and the column segment 213. A first inlet and a second inlet of the circulation channel 23 are formed between two lateral edges of the disc portion 212 in the circumferential direction and the agitation housing 22. An outlet of the circulation channel 23 is formed between a free end of the column segment 213 and the agitation housing 22. When the cleaning apparatus 1 is in the washing phase, the washing water can enter the circulation channel 23 from the first inlet and the second inlet on the lower surface of the main body, respectively, and finally flow out of the outlet of the circulation channel 23 at the free end of the column segment 213.As a result, the agitation device 2 has good water spraying. Since the first annular surface 225 is inclined. Petition 870250105399, dated 11 / 18 / 2025, page 39 / 100 / 76, in relation to the first surface in the radial direction of approach to the central geometric axis, and the ratio between the width d1 of the first annular surface 225 and the width d2 from the outer edge of the agitation housing 22 to the central geometric axis satisfies d2 / d1>18, at least part of the circulation channel defined by the first annular surface 225 and the first surface has a predetermined inclination, which effectively improves the overall smoothness of the inclination of the circulation channel 23. Furthermore, the water spray intensity of the agitation assembly 2 can be improved, so as to achieve a more uniform wash for the laundry and effectively intensify the washing effect of the cleaning apparatus 1 on the laundry.

[0093] An agitation device 2 for a cleaning apparatus 1 according to an embodiment of the present disclosure is described below with reference to Figure 21 to Figure 33. The agitation device 2 can be applied to various cleaning apparatus 1. As an example, in an embodiment of the present disclosure, the agitation device 2 is described as being applied to a pulsator-type washing machine.

[0094] As illustrated in Figures 23 to 33, according to one embodiment of the present disclosure, the agitation device 2 includes an agitation body 10 and a flow guide element 20. The agitation body 10 has a circulation channel 23. The circulation channel 23 extends in the direction of the height of the agitation device 2. For example, in the direction of the height of the agitation device 2 (i.e., a top-down direction shown in Figure 25), the circulation channel 23 extends from bottom to top. The agitation body 10 has a liquid outlet 1033 located in the upper half of the circulation channel 23. The upper half can be interpreted as meaning that the liquid outlet 1033 is located at the top of the circulation channel 23, or the liquid outlet 1033 is located slightly above the middle of the circulation channel 23. Petition 870250105399, dated 11 / 18 / 2025, page 40 / 100 / 76

[0095] The flow guide member 20 is disposed in the agitator body 10. Furthermore, the flow guide member 20 is adapted to block the liquid flowing out of the liquid outlet 1033 to divert the liquid. In an exemplary embodiment of the present disclosure, at least part of the flow guide element 20 may be disposed above the liquid outlet 1033. When the liquid is sprayed out of the liquid outlet 1033, the liquid is blocked by the flow guide member 20 and thus diverts the liquid. In an exemplary embodiment of the present disclosure, the liquid may be sprayed towards the outer radial side of the agitator 2 due to the blockage by the flow guide element 20. This arrangement may not only increase the coverage area of ​​liquid discharged from the agitator 2, but also increase the speed (an impact force) when the liquid comes into contact with the clothing.Therefore, the liquid discharged from agitation device 2 can come into sufficient contact with the laundry located in an upper layer of cleaning device 1, which is beneficial for improving the washing effect of cleaning device 1.

[0096] Therefore, by providing the flow guide member 20, a spray direction of the liquid exiting the liquid outlet 1033 can be changed, which allows the liquid to be sprayed towards the radial outer side of the agitation device 2. In this way, the coverage area of ​​the sprayed liquid from the agitation device 2 can be increased and thus the washing effect of the cleaning apparatus 1 can be improved.

[0097] In some embodiments of the present disclosure, as illustrated in Figure 23, Figure 25, Figure 27 and 30, the agitator body 10 further has a liquid inlet 1034 communicating with the liquid outlet 1033 through the circulation channel 23. Furthermore, in the direction of the height of the agitator device 2 (i.e., the top-down direction shown in Figure 25), the liquid outlet 1033 is located above the liquid inlet 1034. In an exemplary embodiment of the present disclosure, Petition 870250105399, dated 11 / 18 / 2025, page 41 / 100 / 76 the height of the liquid outlet 1033 is higher than the maximum water level in the cleaning device 1.

[0098] When the agitator 2 rotates, the liquid flows from the liquid inlet 1034 to the circulation channel 23 and in the circulation channel 23 to flow to the liquid outlet 1033. A plurality of circulation channels 23 can be formed. For example, two circulation channels 23 can be formed. The two circulation channels 23 can be separated from each other in the circumferential direction of the agitation device 2. In an exemplary embodiment, four circulation channels, six circulation channels or eight circulation channels 23 can be formed. The present disclosure is not limited in this respect. A number of liquid outlet 1033 and a number of liquid inlet 1034 can be equal to a number of circulation channels 23. Furthermore, a plurality of circulation channels 23, a plurality of liquid outlets 1033 and a plurality of liquid inlets 1034 can be arranged in one-to-one correspondence with each other.In an exemplary embodiment, the quantity of liquid output 1033 and the quantity of liquid input 1034 may differ from the number of circulation channels 23. For example, the plurality of liquid outputs 1033 corresponds to one circulation channel 23, or the plurality of liquid inputs 1034 corresponds to one circulation channel 23, or one liquid output 1033 corresponds to the plurality of circulation channels 23, or one liquid input 1034 corresponds to the plurality of circulation channels 23. The present disclosure is not limited in this respect.

[0099] It must be explained that an angle is formed between the liquid inlet 1034 and a horizontal plane. That is, a plane in which the liquid inlet 1034 is located is not parallel to the horizontal plane, or it can also be understood that a line normal to the plane where the liquid inlet 1034 is located is not parallel to a central geometric axis of the stirring device 2. Petition 870250105399, dated 11 / 18 / 2025, p. 42 / 100 / 76

[00100] As an example, the agitator body 10 with two liquid inlets 1034 is described below. In the case where the two liquid inlets 1034 are arranged opposite each other in the circumferential direction of the agitator device 2 (i.e., as illustrated in Figure 30), when the agitator 2 rotates clockwise, the liquid in the cleaning apparatus 1 can be driven to rotate clockwise. When the agitator 2 stops rotating and rotates in the opposite direction instantaneously or after a short delay (rotates counterclockwise), the driven liquid can maintain a previous movement tendency (i.e., clockwise rotation) under the action of inertia.Therefore, the liquid can enter the circulation channel 23 from one of the pluralities of liquid inlets 1034 under the action of inertia and then overcome gravity and flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033. When the agitation device 2 stops rotating and rotates again in the opposite direction instantaneously or after a small delay (the opposite rotation again is clockwise rotation), since the agitation device 2 rotates counterclockwise for a predetermined time, the liquid in the cleaning apparatus 1 may maintain a tendency to rotate counterclockwise due to inertia.Therefore, under the action of inertia, the liquid can enter the circulation channel 23 through the other liquid inlet 1034, then overcome gravity and flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033.

[00101] As illustrated in Figure 30, which is described as an example, when the agitator 2 rotates clockwise, the liquid in the cleaning apparatus 1 can be caused to rotate clockwise. When the agitator 2 stops rotating and rotates in the opposite direction (rotates counterclockwise) instantaneously or after a short delay, Petition 870250105399, dated 11 / 18 / 2025, page 43 / 100 / 76 the actuated liquid can maintain its previous movement tendency (i.e., clockwise rotation) under the action of inertia. Therefore, under the action of inertia, the liquid can enter the circulation channel 23 through the liquid inlet 1034 located above in Figure 30. (It should be explained that in the liquid inlet 1034 located above in Figure 30, the term above refers only to top-down, as shown in Figure 30, which is intended for ease of understanding and does not refer to the top-down direction of the agitation device 2). Then, the liquid can overcome the action of gravity, flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033.When agitator 2 stops rotating and then instantly or after a short delay, the opposite rotation is again clockwise, since agitator 2 rotates counterclockwise for a predetermined time, the liquid in the cleaning apparatus 1 still tends to rotate counterclockwise due to inertia. Therefore, under the action of inertia, the liquid can enter the circulation channel 23 through the liquid inlet 1034 located below in Figure 30. (It should be explained that in the liquid inlet 1034 located below in Figure 30, the term "below" refers only to "from top to bottom," as shown in Figure 30, which is intended for ease of understanding and does not refer to the top-to-bottom direction of the agitation device 2). Then, the liquid can overcome the action of gravity, flow upwards along the circulation channel 23 to the liquid outlet 1033, and finally be sprayed out of the liquid outlet 1033.

[00102] Furthermore, the two liquid inlets 1034 can also be arranged apart from each other in the circumferential direction of the stirring device 2. It should be understood that, in a case where the two liquid inlets 1034 are arranged opposite each other in the circumferential direction of the stirring device 2 (i.e., as shown in Figure 30), the Petition 870250105399, dated 11 / 18 / 2025, page 44 / 100 / 76 liquid can be sprayed out of liquid outlet 1033 every time the agitator 2 changes direction of rotation. In the case where the two liquid inlets 1034 are arranged apart from each other in the circumferential direction of the agitator 2, the liquid can be sprayed out of liquid outlet 1033 each time the direction of rotation of the agitator 2 changes twice.

[00103] When agitation device 2 is placed in the pulsator washing machine, agitation device 2 can perform rotation and agitation, which reduces the likelihood of tangling of the clothes to improve the washing effect of the pulsator washing machine. Furthermore, since the clothes located in the top layer have less contact with the washing water and may not be fully soaked, when agitation device 2 of the present disclosure rotates, agitation device 2 can drive the liquid from liquid inlet 1034 to liquid outlet 1033 in order to spray the liquid out of agitation device 2. The liquid sprayed out of agitator 2 can come into contact with the clothes located in the top layer of the cleaning apparatus 1. Therefore, the washing effect of the cleaning apparatus 1 can be improved.In addition, agitation device 2 can allow the liquid in the pulsator washing machine to circulate, which is beneficial for increasing the detergent dissolution rate.

[00104] In an exemplary embodiment of the present disclosure, the pulsator washing machine is equipped with a drive motor. The agitation device 2 can be arranged in the pulsator washing machine and connected to a motor shaft 50 of the drive motor. The drive motor is adapted to drive the agitation device 2 to rotate via the motor shaft 50. The central geometric axis of the agitation device 2 can coincide with a central geometric axis of the pulsator-type washing machine.

[00105] In some forms of the present disclosure, as Petition 870250105399, dated 11 / 18 / 2025, page 45 / 100 / 76 illustrated in Figure 25, Figure 29 and Figure 32, in the direction of the height of the agitation device 2 (that is, the top-down direction shown in Figure 25), the agitation body 10 has a first end 104 and a second end 105 opposite to each other. The first end 104 is located above the second end 105. The first end 104 has a liquid outlet 1033. The second end 105 has a liquid inlet 1034. This arrangement allows the liquid to be sprayed from a higher position, which is beneficial for increasing the coverage area of ​​the sprayed liquid from the agitator 2. Therefore, the sprayed liquid from the agitator 2 can be more sufficiently in contact with the laundry located in the upper layer of the cleaning apparatus 1, which is beneficial for improving the washing effect of the cleaning apparatus 1.

[00106] In some embodiments of the present disclosure, the liquid outlet 1033 is located in the upper half of the circulation channel 23. Furthermore, the liquid outlet 1033 is not formed at the first end 104 of the agitator body 10. In this way, the liquid sprayed from the agitator 2 has a larger coverage area.

[00107] In some embodiments of the present disclosure, as illustrated in Figure 23, Figure 25 and Figure 32, the circulation channel 23 may include a first flow channel segment 1031 and a second flow channel segment 1032 communicating with the first flow channel segment 1031. Furthermore, the first flow channel segment 1031 and the second flow channel segment 1032 may be arranged in the direction of the height of the agitation device 2 (i.e., in the vertical direction illustrated in Figure 32). Because the first flow channel segment 1031 and the second flow channel segment 1032 are arranged in the direction of the height of the agitation device 2, the liquid can be efficiently guided to the liquid outlet 1033.

[00108] In some forms of the present disclosure, as Petition 870250105399, dated 11 / 18 / 2025, page 46 / 100 / 76 illustrated in Figure 23, Figure 25 and Figure 32, the second segment of the flow channel 1032 and the liquid outlet 1033 are in communication with each other through the first segment of the flow channel 1031. The first segment of the flow channel 1031 extends in the direction of the height of the agitation device 2. The first segment of the flow channel 1031 and the liquid inlet 1034 are in communication with each other through the second segment of the flow channel 1032.

[00109] In some exemplary embodiments of the present disclosure, in the vertical direction shown in Figure 25, one end of the second segment of the flow channel 1032 distant from the first segment of the flow channel 1031 (i.e., a lower end of the second segment of the flow channel 1032) is in fluid communication with the liquid inlet 1034. One end of the first segment of the flow channel 1031 distant from the second segment of the flow channel 1032 (i.e., an upper end of the first segment of the flow channel 1031) is in fluid communication with the liquid outlet 1033. One end of the first segment of the flow channel 1031 is close to one end of the second segment of the flow channel 1032 (i.e., a lower end of the first segment of the flow channel 1031 and an upper end of the second segment of the flow channel 1032 are close to each other), and these two ends are in fluid communication with each other.The liquid can enter the second segment of the flow channel 1032 from the liquid inlet 1034, then enter the first segment of the flow channel 1031 from the second segment of the flow channel 1032 and be sprayed from the liquid outlet 1033 out of the agitation device 2. By configuring the first segment of the flow channel 1031 to extend in the direction of the height of the agitation device 2, the liquid can reach the liquid outlet 1033 after flowing a relatively short distance, which helps to increase the water spraying rate of the agitation device 2. Petition 870250105399, dated 11 / 18 / 2025, page 47 / 100 / 76

[00110] In some embodiments of the present disclosure, as illustrated in Figure 23, Figure 25, and Figure 32, the second segment of the flow channel 1032 has an inclined flow guide surface 10321 on an inner wall of the second segment of the flow channel 1032. When the agitator 2 rotates, the inclined surface of the flow guide 10321 directs the liquid flowing into the circulation channel 23 to the first segment of the flow channel 1031. The inclined surface of the flow guide 10321 may be constructed in an arc-shaped inclined surface. For example, the inclined surface of the flow guide 10321 may be constructed in a circular arc-shaped inclined surface or in an elliptical arc-shaped inclined surface. The arc-shaped inclined surface of the flow guide 10321 may project away from the liquid inlet 1034.This arrangement allows the liquid entering the second segment of the flow channel 1032 through the liquid inlet 1034 to flow smoothly into the first segment of the flow channel 1031. Therefore, the impact of the liquid on an inner wall of the circulation channel 23 is reduced, thus increasing the liquid flow rate.

[00111] In some embodiments of the present disclosure, as illustrated in Figure 33, the flow guide member 20 has a first flow guide segment 201. In the direction of the height of the agitator device 2 (i.e., the top-down direction shown in Figure 32), the first flow guide segment 201 may be located above the liquid outlet 1033. Furthermore, the first flow guide segment 201 may be opposite the liquid outlet 1033 and may be separated from the liquid outlet 1033. When liquid is sprayed out of the liquid outlet 1033, the liquid may reach the first flow guide segment 201 under the action of inertia. Then, the liquid may be sprayed in a direction extending the first flow guide segment 201. In this way, the liquid sprayed out of the liquid outlet 1033 may flow in the direction extending the first Petition 870250105399, dated 11 / 18 / 2025, page 48 / 100 / 76 flow guide segment 201, which facilitates the expansion of the coverage area of ​​the sprayed liquid outside the agitation device 2.

[00112] In some embodiments of the present disclosure, as illustrated in Figure 33, in the first direction, a spacing distance between the first flow guide segment 201 and the liquid outlet 1033 is H, where 5 mm <H<8 mm. Em uma modalidade exemplar da presente revelação, na direção de altura do dispositivo de agitação 2 (isto é, na direção vertical mostrada na Figura 32), a distância de espaçamento entre o primeiro segmento guia de fluxo 201 e a saída de líquido 1033 pode ser qualquer valor entre 5 mm e 8 mm. Por exemplo, a distância de espaçamento pode ser de 5 mm, 6 mm, 7 mm ou 8 mm.

[00113] The spacing distance between the first flow guide segment 201 and the liquid outlet 1033 can refer to a spacing distance between an outer wall of a structure forming the liquid outlet 1033 and the first flow guide segment 201. Furthermore, the first flow guide segment 201 and the outer wall of the structure forming the liquid outlet 1033 can together define a liquid discharge port 205. In the direction of the height of the agitator 2 (i.e., the top-down direction shown in Figure 32), the height of the liquid discharge port 205 can be any value between 5 mm and 8 mm. This arrangement can cause the liquid guided by the first flow guide segment 201 to take the form of a water film and fall on all parts of a top layer of liquid in the cleaning apparatus 1. Therefore, the washing effect of the cleaning apparatus 1 is improved.

[00114] In some embodiments of the present disclosure, the first flow guide segment 201 is arranged at an angle relative to the axial direction of the liquid outlet 1033. For example, the first flow guide segment 201 is arranged at an angle α relative to the axial direction of the liquid outlet 1033. By adjusting the angle between the first flow guide segment Petition 870250105399, dated 11 / 18 / 2025, page 49 / 100 / 76 201 and the axial direction of the liquid outlet 1033, a flow direction of the liquid sprayed out of the agitation device 2 can be changed. In this way, an agitation device 2 with different spray directions can be produced as desired, which is beneficial for improving the product's competitiveness.

[00115] In some embodiments of the present disclosure, as illustrated in Figure 33, the first flow guide segment 201 can be perpendicular to the axial direction of the liquid outlet 1033. That is, the angle between the first flow guide segment 201 and the axial direction of the liquid outlet 1033 is 90 degrees. In this way, the liquid can be sprayed out of the agitator 2 in the horizontal direction. Furthermore, the liquid sprayed from the agitator 2 can be spread relatively uniformly over all parts of the upper layer of liquid in the cleaning apparatus 1.

[00116] In some embodiments of the present disclosure, as illustrated in Figure 33, the flow guide member 20 further has a second flow guide segment 202 adjacent to the first flow guide segment 201 and connected to the agitator body 10. The second flow guide segment 202 may be constructed in the form of an arc. The second flow guide segment 202 may be adapted to block the liquid exiting the liquid outlet 1033 to divert the liquid. In an exemplary embodiment of the present disclosure, one end of the second flow guide segment 202 is connected to the agitator body 10, and the other end of the second flow guide segment 202 is connected to the first flow guide segment 201. The second flow guide segment 202 may be constructed in the form of a circular arc or in the form of an elliptical arc. The second arc-shaped flow guide segment 202 may project away from the liquid outlet 1033.In another exemplary embodiment of the present disclosure, the second flow guide segment 202 may project outward from the liquid outlet 1033 and in the axial direction of the device. Petition 870250105399, dated 11 / 18 / 2025, page 50 / 100 / 76 agitation 2. In an exemplary embodiment of the present disclosure, the second flow guide segment 202 is tangent to the agitation body 10. Furthermore, the second flow guide segment 202 is tangent to the first flow guide segment 201.

[00117] Both the first flow guide segment 201 and the second flow guide segment 202 are adapted to block the liquid exiting the liquid outlet 1033. For example, at least part of the second flow guide segment 202 is adapted to block the liquid exiting the liquid outlet 1033. In addition, at least part of the first flow guide segment 201 is adapted to block the liquid exiting the liquid outlet 1033. When the liquid is sprayed out of the liquid outlet 1033, the liquid may come into contact at least partially with the second flow guide segment 202. The second flow guide segment 202 may guide the liquid in contact with the second flow guide segment 202 to the first flow guide segment 201. Then, the liquid may be sprayed in the direction of extension of the first flow guide segment 201.By constructing the second flow guide segment 202 in an arc shape, the impact between the liquid and the flow guide member 20 can be reduced, which is beneficial for reducing the loss of kinetic energy of the liquid and thus can increase the spray distance of the liquid.

[00118] In some embodiments of the present disclosure, as illustrated in Figure 25 and Figure 32, the circulation channel 23 has an inner channel wall 101 and an outer channel wall 102. The outer channel wall 102 is located on a radial outer side of the inner channel wall 101. One end of the flow guide member 20 may be connected to the inner channel wall 101. Furthermore, the flow guide member 20 may extend toward the outer channel wall 102. In the direction of the height of the agitator 2 (i.e., the top-down direction shown in Figure 32), an orthographic projection of the other end of the member of Petition 870250105399, dated 11 / 18 / 2025, page 51 / 100 / 76 flow guide 20 is located outside an orthographic projection of the circulation channel 23. That is, the orthographic projection of the other end of the flow guide member 20 is located on a radial outer side of an orthographic projection of the outer wall of the channel 102. With this arrangement, all the liquid exiting the liquid outlet 1033 can be guided, which can ensure a flow guiding effect of the flow guide member 20.

[00119] In some embodiments of the present disclosure, as illustrated in Figure 33, a guide channel 204 is formed between the flow guide member 20 and the liquid outlet 1033. The guide channel 204 may have one end in fluid communication with the liquid outlet 1033 and the other end as the liquid discharge port 205. A liquid flow area of ​​the other end of the guide channel 204 is equal to a liquid flow area of ​​a portion of the circulation channel 23 that is close to the liquid outlet 1033. That is, a liquid flow area of ​​the upper half of the circulation channel 23 remains unchanged, meaning that there is no way in which a circulation path gradually expands or contracts in the upper half of the circulation channel 23. Furthermore, the liquid flow area of ​​the upper half of the circulation channel 23 is equal to a liquid flow area of ​​the liquid discharge port 205.This arrangement can reduce the loss of liquid pressure in a flow process, allowing the liquid sprayed out of the agitation device 2 to have greater kinetic energy, which is beneficial for increasing the coverage area of ​​the liquid sprayed out of the agitation device 2.

[00120] In some embodiments of the present disclosure, as illustrated in Figure 33, the flow guide element 20 may have a flow guide portion 203 formed at the other end of the flow guide element 20. The flow guide portion 203 may extend towards a position under the agitation device 2. In another exemplary embodiment of the present disclosure, the flow guide portion 203 may be constructed in Petition 870250105399, dated 11 / 18 / 2025, page 52 / 100 / 76 arc shape. The flow guide portion 203 may extend towards the outer radial side of the agitation device 2 and extend to a position below the agitation device 2. Furthermore, the arc-shaped flow guide portion 203 may project away from the liquid outlet 1033 and away from the axial direction of the agitation device 2.

[00121] In an exemplary embodiment of the present disclosure, as illustrated in Figure 33, the flow guide element 20 may include a first flow guide section 201, a second flow guide section 202, and a flow guide portion 203. One end of the second flow guide segment 202 is connected to the agitator body 10, and the other end of the second flow guide segment 202 is connected to one end of the first flow guide segment 201. The first flow guide segment 201 is connected to the flow guide portion 203 at the other end of the first flow guide segment 201. By providing the flow guide portion 203, the liquid discharged through the liquid discharge orifice 205 can be directed to change the flow direction of the liquid sprayed by the agitator device 2.Furthermore, by configuring the flow guide portion 203 in an arc shape, it is possible to reduce the impact between the liquid and the flow guide portion 203, which helps to decrease the loss of kinetic energy of the liquid and, consequently, increase the spray distance of the liquid.

[00122] In some embodiments of the present disclosure, as illustrated in Figure 33, in a radial direction of the agitation device 2, the flow guide portion 203 is located externally to the liquid outlet 1033. In an exemplary embodiment, it should be understood that, in the height direction of the agitation device 2 (i.e., in the vertical direction shown in Figure 32), an orthographic projection of the flow guide portion 203 is located outside an orthographic projection of the liquid outlet orifice 1033 (i.e., on one side of the orthographic projection of the outlet orifice). Petition 870250105399, dated 11 / 18 / 2025, page 53 / 100 / 76 liquid 1033 opposite the agitation device 2). Thus, an arrangement of the flow guide portion 203 may be suitable, and the coverage area of ​​the liquid sprayed from the agitation device 2 may be enlarged.

[00123] In some embodiments of the present disclosure, the flow guide element 20 can be detachably connected to the agitator body 10. In another exemplary embodiment of the present disclosure, the flow guide element 20 can be connected to the agitator body 10 by fitting, or the flow guide element 20 can be connected to the agitator body 10 by means of a thread, or the flow guide element 20 can be connected to the agitator body 10 by other removable means. It should be understood that the user can change the direction of the liquid sprayed out of the agitator 2 by replacing the flow guide member 20. By constructing the flow guide member 20 and the agitator body 10 to be detachably connected to each other, the flow guide member 20 can be easily replaced by the user. As a result, the direction of the liquid sprayed from the agitator 2 can be changed by the user as desired.

[00124] A cleaning apparatus 1, according to the embodiments of the present disclosure, includes the agitation device 2 as embodied above. The cleaning apparatus 1 may be a pulsating washing machine, but is not limited to a pulsating washing machine. The agitation device 2, according to the embodiments of the present disclosure, may guide the liquid from the liquid inlet 1034 to the liquid outlet 1033, in order to be sprayed out of the agitation device 2 when it is rotating. The liquid sprayed out of the agitation device 2 may fall back into the upper layer of liquid in the cleaning apparatus 1. Therefore, the detergent content of the liquid in the upper layer and the detergent content of the liquid in the lower layer may be equal, which is beneficial. Petition 870250105399, dated 11 / 18 / 2025, page 54 / 100 / 76 to improve the washing effect of cleaning device 1.

[00125] An agitation device 2 for a cleaning apparatus 1 according to the embodiments of the present disclosure is described below with reference to Figure 21 to Figure 30. The agitation device 2 can be applied to various cleaning apparatus 1. As an example, in one embodiment of the present disclosure, the agitation device 2 is described as being applied to a pulsator-type washing machine.

[00126] As illustrated in Figures 23 to 30, the agitation device 2, according to one embodiment of the present disclosure, includes an agitation body 10 provided with a circulation channel 23. In some exemplary embodiments of the present disclosure, the circulation channel 23 may extend in the height direction of the agitation device 2. For example, in the height direction of the agitation device 2 (i.e., the top-down direction shown in Figure 25), the circulation channel 23 extends from bottom to top. The agitation body 10 has a liquid inlet 1034 and a liquid outlet 1033. The liquid inlet 1034 is in communication with the liquid outlet 1033 through the circulation channel 23. The liquid outlet 1033 is located above the liquid inlet 1034. In one exemplary embodiment of the present disclosure, the height of the liquid outlet 1033 is higher than the maximum water level in the cleaning apparatus 1.

[00127] In the direction of the height of the agitator 2, the liquid inlet 1034 is located at a lower end of the agitator body 10. Furthermore, a lower wall of the liquid inlet 1034 is arc-shaped. In some exemplary embodiments of the present disclosure, the lower wall 10341 of the liquid inlet 1034 may be constructed in the shape of a circular arc, or the lower wall 10341 of the liquid inlet 1034 may be constructed in the shape of an elliptical arc. Furthermore, the lower wall 10341 of the liquid inlet 1034 projects away from the agitator body 10. That is, in the direction of the height of the agitator 2, the lower wall 10341 of the liquid inlet Petition 870250105399, dated 11 / 18 / 2025, page 55 / 100 / 76 liquid 1034 projects downwards.

[00128] Therefore, by constructing the lower wall 10341 of the liquid inlet 1034 in an arc shape and constructing the lower wall 10341 of the liquid inlet 1034 in a structure that projects away from the agitation body 10, the liquid flow area of ​​the liquid inlet 1034 can be increased and the liquid inlet volume of the agitation device 2 can be enlarged, which increases the water spray volume of the agitation device 10. Therefore, the washing effect of the cleaning apparatus 1 is improved.

[00129] In some exemplary embodiments of the present disclosure, the lower wall 10341 of the liquid inlet 1034 extends gradually upward from an outer radial side of the agitator body 10 to an inner radial side of the agitator body 10. When the agitator 2 rotates, the liquid flows from the liquid inlet 1034 to the circulation channel 23 and flows to the liquid outlet 1033 along the circulation channel 23.

[00130] As an example, the agitator body 10 with two liquid inlets 1034 is described below. In the case where the two liquid inlets 1034 are arranged opposite each other in the circumferential direction of the agitator device 2 (i.e., as illustrated in Figure 30), when the agitator 2 rotates clockwise, the liquid in the cleaning apparatus 1 can be driven to rotate clockwise. When the agitator 2 stops rotating and rotates in the opposite direction instantaneously or after a short delay (rotates counterclockwise), the driven liquid can maintain a previous movement tendency (i.e., clockwise rotation) under the action of inertia.Therefore, the liquid can enter the circulation channel 23 from one of the pluralities of liquid inlets 1034 under the action of inertia and then overcome the action of gravity and flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033. When the agitator 2. Petition 870250105399, dated 11 / 18 / 2025, p. 56 / 100 / 76 interrupts the rotation and rotates again in the opposite direction instantaneously or after a short delay (the opposite rotation is again the clockwise rotation), because the agitator 2 rotates counterclockwise for a predetermined time, the liquid in the cleaner 1 may maintain a tendency to rotate counterclockwise due to inertia. Therefore, under the action of inertia, the liquid may enter the circulation channel 23 through the other liquid inlet 1034, then overcome the action of gravity and flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033.

[00131] As illustrated in Figure 30, which is described as an example, when the agitator 2 rotates clockwise, the liquid in the cleaning apparatus 1 can be caused to rotate clockwise. When the agitator 2 stops rotating and rotates in the opposite direction (rotates counterclockwise) instantaneously or after a short delay, the driven liquid can maintain the previous movement tendency (i.e., clockwise rotation) under the action of inertia. Therefore, under the action of inertia, the liquid can enter the circulation channel 23 through the liquid inlet 1034 located above in Figure 30. (It should be explained that in the liquid inlet 1034 located above in Figure 30, the term above refers only to top-down, as shown in Figure 30, which is intended for ease of understanding and does not refer to the top-down direction of the agitator 2).Then, the liquid can overcome the action of gravity, flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033. When the agitator 2 stops rotating and then rotates in the opposite direction instantly or after a short delay (the opposite rotation is again clockwise), as the agitator 2 rotates counterclockwise for a predetermined time, the liquid in the cleaning apparatus 1. Petition 870250105399, dated 11 / 18 / 2025, page 57 / 100 / 76 still maintains the tendency to rotate counterclockwise due to inertia. Therefore, under the action of inertia, the liquid can enter the circulation channel 23 through the liquid inlet 1034 located below in Figure 30. (It should be explained that in the liquid inlet 1034 located below in Figure 30, the term below refers only to top-down, as shown in Figure 30, which is intended for ease of understanding and does not refer to the top-down direction of the agitation device 2). Then, the liquid can overcome the action of gravity, flow upwards along the circulation channel 23 to the liquid outlet 1033 and finally be sprayed out of the liquid outlet 1033.

[00132] Furthermore, the two liquid inlets 1034 can also be arranged apart from each other in the circumferential direction of the agitator 2. It should be understood that, in a case where the two liquid inlets 1034 are arranged opposite each other in the circumferential direction of the agitator 2 (i.e., as shown in Figure 30), the liquid can be sprayed out of the liquid outlet 1033 each time the agitator 2 changes its direction of rotation. In the case where the two liquid inlets 1034 are arranged apart from each other in the circumferential direction of the agitator 2, the liquid can be sprayed out of the liquid outlet 1033 each time the direction of rotation of the agitator 2 changes twice.

[00133] When agitation device 2 is placed in the pulsator washing machine, agitation device 2 can perform rotation and agitation, which reduces the likelihood of tangling of the clothes to improve the washing effect of the pulsator washing machine. Furthermore, since clothes located in the top layer have less contact with the washing water and may not be fully soaked, when agitation device 2 of the present disclosure rotates, agitation device 2 can drive the liquid from liquid inlet 1034 to liquid outlet 1033, a Petition 870250105399, dated 11 / 18 / 2025, page 58 / 100 / 76, in order to spray the liquid out of the agitation device 2. The liquid sprayed out of the agitation device 2 can come into contact with the laundry located in the upper layer of the cleaning apparatus 1, which can improve the washing effect of the cleaning apparatus 1. In addition, the agitation device 2 can cause the liquid in the pulsator washing machine to circulate upwards, which is beneficial for increasing the detergent dissolution rate. Furthermore, the detergent content of the liquid in the upper layer and the detergent content of the liquid in the lower layer can be equalized, which is beneficial for improving the washing effect of the cleaning apparatus 1.

[00134] In an exemplary embodiment of the present disclosure, the pulsating washing machine is equipped with a drive motor. The agitation device 2 can be disposed in the pulsating washing machine and connected to the motor shaft of the drive motor. The drive motor is adapted to drive the agitation device 2 to rotate via the motor shaft. The central geometric axis of the agitation device 2 can coincide with the central geometric axis of the pulsating washing machine. In an exemplary embodiment of the present disclosure, the agitation device 2 is placed in a holding tank.

[00135] In some embodiments of the present disclosure, as illustrated in Figure 22 and Figure 25, a lower end 10342 of the lower wall 10341 of the liquid inlet 1034 is separated from a lower wall 30 of the holding tank of the cleaning apparatus 1. That is, in the direction of the height of the agitator 2 (i.e., the top-down direction shown in Figure 25), there is a predetermined distance between the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 and the lower wall 30 of the holding tank of the cleaning apparatus 1. Therefore, when the agitator 2 rotates, the agitator 2 does not interfere with the holding tank, which prevents damage to the agitator 2 and / or the holding tank, which is beneficial for Petition 870250105399, dated 11 / 18 / 2025, page 59 / 100 / 76 improve the reliability of the use of agitator 2.

[00136] It should be noted that the holding tub can be configured to hold the laundry. For example, a holding tub on a pulsating washing machine is configured to hold the laundry.

[00137] In some embodiments of the present disclosure, a spacing distance between the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 and the lower wall 30 of the holding tank is H, where 4 mm <H<10 mm. Em uma modalidade exemplar da presente revelação, na direção de altura do dispositivo de agitação 2 (isto é, na direção vertical mostrada na Figura 25), a distância de espaçamento entre a extremidade inferior 10342 da parede inferior 10341 da entrada de líquido 1034 e a parede inferior 30 da cuba de retenção pode ser qualquer valor entre 4 mm e 10 mm. Por exemplo, a distância de espaçamento pode ser de 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm ou 10 mm.It should be understood that if the spacing distance between the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 and the lower wall 30 of the holding tank is too small, the agitation device 2 may interfere with the lower wall 30 of the holding tank during rotation. If the spacing distance between the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 and the lower wall 30 of the holding tank is too large, the liquid flow area of ​​the liquid inlet 1034 may be relatively small, affecting the liquid inlet volume. Therefore, the spacing distance between the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 and the lower wall 30 of the holding tank is defined as any value between 4 mm and 10 mm.Therefore, interference with the lower wall 30 of the holding tank can be avoided when the stirring device 2 rotates, thus increasing the liquid inlet volume of the stirring device 2.

[00138] In some embodiments of the present disclosure, H may Petition 870250105399, dated 11 / 18 / 2025, p. 60 / 100 / 76 satisfy 5 mm <H<8 mm. Em uma modalidade exemplar da presente revelação, a distância de espaçamento entre a extremidade inferior 10342 da parede de fundo 10341 da entrada de líquido 1034 e a parede de fundo 30 da cuba de retenção pode ser qualquer valor entre 5 mm e 8 mm. Por exemplo, a distância de espaçamento pode ser de 5 mm, 6 mm, 7 mm ou 8 mm. Em uma modalidade exemplar da presente revelação, a distância de espaçamento entre a extremidade inferior 10342 da parede inferior 10341 da entrada de líquido 1034 e a parede inferior 30 da cuba de retenção é de 5 mm. Essa disposição pode tornar a distância de espaçamento entre a extremidade inferior 10342 da parede inferior 10341 da entrada de líquido 1034 e a parede inferior 30 da cuba de retenção mais razoável, o que melhora ainda mais a confiabilidade do uso do dispositivo de agitação 2.

[00139] In some embodiments of the present disclosure, in a radial direction of the agitation device 2, a liquid flow area of ​​the liquid inlet 1034 gradually increases from an outer radial side of the agitation body 10 to an inner radial side of the agitation body 10. That is, the liquid flow area of ​​the liquid inlet 1034 gradually decreases from the inner radial side of the agitation body 10 to the outer radial side of the agitation body 10. Therefore, the liquid inlet 1034 can be constructed in a more reasonable form such that there is no large eddy current in the liquid at the liquid inlet 1034. As a result, resistance to liquid flow can be reduced. In this way, the liquid can flow smoothly from the liquid inlet 1034 to the circulation channel 23, which is conducive to increasing the liquid inlet volume of the agitation device 2.

[00140] In some embodiments of the present disclosure, as illustrated in Figure 23, Figure 25, Figures 27 and 30, the liquid inlet 1034 is open in the circumferential direction of the stirring device 2. That is, an angle is formed between the liquid inlet 1034 and the plane Petition 870250105399, dated 11 / 18 / 2025, page 61 / 100 / 76 horizontal. That is, the plane in which the liquid inlet 1034 is located is not parallel to the horizontal plane, or it should also be understood that the line normal to the plane where the liquid inlet 1034 is located is not parallel to the central geometric axis of the agitation device 2. In this way, the liquid driven by the agitator 2 can smoothly enter the circulation channel 23 from the liquid inlet 1034 under the action of inertia, which is beneficial to increase the liquid inlet volume of the agitator 2.

[00141] In some embodiments of the present disclosure, as illustrated in Figure 23, Figure 25, Figure 27 and 30, a plurality of liquid inlets can be formed. At least two of the plurality of liquid inlets have different opening orientations. That is, at least two of the plurality of liquid inlets are arranged opposite each other in the circumferential direction of the agitator 2 (i.e., as shown in Figure 30). That is, one liquid inlet 1034 opens clockwise and the other liquid inlet 1034 opens counterclockwise. With this arrangement, liquid can be sprayed out of the liquid outlet 1033 every time the agitator 2 changes its direction of rotation, which increases the frequency with which the agitator 2 sprays liquid.

[00142] In some embodiments of the present disclosure, as illustrated in Figure 27 and Figure 30, the plurality of liquid inlets 1034 can be arranged sequentially at intervals in the circumferential direction of the agitation device 2. In some exemplary embodiments of the present disclosure, the plurality of liquid inlets 1034 can be arranged at uniform intervals in the circumferential direction of the agitation device 2. For example, four liquid inlets 1034 can be formed. The four liquid inlets 1034 can be arranged at uniform intervals sequentially in the circumferential direction of the agitation device 2. That is, the angle between each two adjacent liquid inlets 1034 is 90 degrees. In an exemplary embodiment, the Petition 870250105399, dated 11 / 18 / 2025, page 62 / 100 / 76. A plurality of liquid inlets 1034 can be arranged at sequential intervals in the circumferential direction of the agitation device 2, with a non-uniform interval angle. For example, four liquid inlets 1034 can be arranged at sequential intervals in the circumferential direction of the agitation device 2. Furthermore, an angle between two adjacent liquid inlets 1034 of the four liquid inlets 1034 is 60 degrees, and an angle between two other adjacent liquid inlets 1034 of the four liquid inlets 1034 is 120 degrees. This arrangement can allow the plurality of liquid inlets 1034 to be arranged in a variety of patterns to suit different actual needs.

[00143] In some embodiments of the present disclosure, the spacing distance between two adjacent liquid inlets 1034 is the same.In this way, the liquid inlet volume of each liquid inlet 1034 can be approximately equal, and the mass distribution everywhere when the stirring device 2 rotates can be uniform, which prevents a center of gravity from shifting when the stirring device 2 rotates. Therefore, the stirring device 2 can be prevented from tilting during rotation, which is beneficial for improving the reliability of the use of the stirring device 2.

[00144] In some embodiments of the present disclosure, the lower end 10342 of the bottom wall 10341 of each liquid inlet 1034 is offset from the bottom wall 30 of the holding vessel by the same distance. For example, two liquid inlets 1034 may be formed. A distance between a lower end 10342 of a bottom wall 10341 of each of the two liquid inlets 1034 and the bottom wall 30 of the holding vessel is 5 mm. In this way, a liquid flow area of ​​each liquid inlet 1034 can be the same, and a liquid inlet volume of each liquid inlet 1034 can be the same, which allows for mass distribution at all positions when the agitation device Petition 870250105399, dated 11 / 18 / 2025, page 63 / 100 / 76 rotates, be uniform. Furthermore, the center of gravity can be prevented from shifting when the agitation device 2 rotates, which is beneficial for improving the reliability of the use of the agitation device 2.

[00145] In some embodiments of the present disclosure, as illustrated in Figure 27, Figure 29 and Figure 30, the lower wall 10341 of each of the pluralities of liquid inlets 1034 has a lower end 10342 at an end of the lower wall 10341 distant from the circulation channel 23. In another embodiment, it should be understood that, in the radial direction of the agitation device 2, an outer radial end of the lower wall 10341 of the liquid inlet 1034 has the lowest end 10342. Furthermore, the lowest end 10342 is tangent to a plane where the lower end of the agitation body 10 is located.

[00146] As illustrated in Figure 27, the agitator body 10 may have a flange 11. In a radial direction of the agitator body 10, the flange 11 is located at the radial outer end of the agitator body 10. That is, a plane is defined. The plane is perpendicular to the central geometric axis of the agitator device 2 (it should also be understood that the line normal to the plane is parallel to the central geometric axis of the agitator device 2). An orthographic projection of the flange 11 onto the plane is located on a radial outer side of the liquid inlet 1034. The flange 11 extends in the direction of the height of the agitator device 2. The lower wall 10341 of the liquid inlet 1034 has its lower end 10342 connected to a lower end of the flange 11.

[00147] Furthermore, the lower end 10342 of the lower wall 10341 of the liquid inlet 1034 is tangent to the plane where the lower end of the agitator body 10 is located. In an exemplary embodiment of the present disclosure, a plane X is defined. Plane X is perpendicular to the central geometric axis of the agitator device 2 (it must Petition 870250105399, dated 11 / 18 / 2025, page 64 / 100 / 76, also understands that a line normal to plane X is parallel to the central geometric axis of the agitation device 2). The plane where the lower end of the agitator body 10 is located is plane X. The lowest end 10342 is tangent to plane X. With this arrangement, the liquid flow area of ​​the liquid inlet 1034 can be further increased, which is beneficial for increasing the liquid inlet volume of the agitator 10, increasing the water spray volume of the agitator 10, and thus improving the washing effect of the cleaning apparatus 1.

[00148] In some embodiments of the present disclosure, as illustrated in Figure 25 and Figure 29, in the direction of the height of the agitator 2 (i.e., the top-down direction shown in Figure 25), the agitator body 10 has the first end 104 and the second end 105 opposite each other.The first end 104 is located above the second end 105. The first end 104 has the liquid outlet 1033. The second end 105 has the liquid inlet 1034. This arrangement allows the liquid to be sprayed from a higher position, which is beneficial for increasing the coverage area of ​​the sprayed liquid from the agitator 2. Therefore, the sprayed liquid from the agitator 2 can be more sufficiently in contact with the laundry located in the upper layer of the cleaning apparatus 1, which is beneficial for improving the washing effect of the cleaning apparatus 1.

[00149] In some embodiments of the present disclosure, the liquid outlet 1033 is located in the upper half of the circulation channel 23. Furthermore, the liquid outlet 1033 is not formed at the first end 104 of the agitator body 10. As a result, the liquid sprayed from the agitator device 2 can have a larger coverage area.

[00150] In some embodiments of the present disclosure, as illustrated in Figures 23 and 25, the circulation channel 23 may include the first segment of the flow channel 1031 and the second segment of the flow channel. Petition 870250105399, dated 11 / 18 / 2025, page 65 / 100 / 76 1032 in communication with the first segment of the flow channel 1031. Furthermore, the first segment of the flow channel 1031 and the second segment of the flow channel 1032 can be arranged in the direction of the height of the agitation device 2 (i.e., in the vertical direction illustrated in Figure 32). By arranging the first segment of the flow channel 1031 and the second segment of the flow channel 1032 in the direction of the height of the agitation device 2, the liquid can be smoothly guided to the liquid outlet 1033.

[00151] In some embodiments of the present disclosure, as illustrated in Figures 23 and 25, the second segment of the flow channel 1032 and the liquid outlet 1033 are in communication with each other through the first segment of the flow channel 1031. The first segment of the flow channel 1031 extends in the direction of the height of the agitation device 2. The first segment of the flow channel 1031 and the liquid inlet 1034 are in communication with each other through the second segment of the flow channel 1032.

[00152] In some exemplary embodiments of the present disclosure, in the vertical direction shown in Figure 25, one end of the second segment of the flow channel 1032 distant from the first segment of the flow channel 1031 (i.e., the lower end of the second segment of the flow channel 1032) is in fluid communication with the liquid inlet 1034.One end of the first segment of the flow channel 1031, distant from the second segment of the flow channel 1032 (that is, the upper end of the first segment of the flow channel 1031), is in fluid communication with the liquid outlet 1033. The end of the first segment of the flow channel 1031 is close to the end of the second segment of the flow channel 1032 (that is, the lower end of the first segment of the flow channel 1031 and the upper end of the second segment of the flow channel 1032 are close to each other), and these two ends are in fluid communication with each other. Liquid can enter the second segment of the flow channel 1032 from the liquid inlet 1034, then enter the... Petition 870250105399, dated 11 / 18 / 2025, page 66 / 100 / 76 first segment of flow channel 1031 from the second segment of flow channel 1032 and be sprayed from liquid outlet 1033 out of agitation device 2. By configuring the first segment of flow channel 1031 to extend in the direction of the height of agitation device 2, the liquid can reach liquid outlet 1033 after flowing a relatively short distance, which can increase the water spray rate from agitation device 2.

[00153] In some embodiments of the present disclosure, as illustrated in Figures 23 and 25, the second segment of the flow channel 1032 has the inclined surface of the flow guide 10321 on the inner wall of the second segment of the flow channel 1032. When the agitator 2 rotates, the inclined surface of the flow guide 10321 directs the liquid flowing into the circulation channel 23 to the first segment of the flow channel 1031. The inclined surface of the flow guide 10321 can be constructed in the form of an arc. For example, the inclined surface of the flow guide 10321 can be constructed in the form of a circular arc or an elliptical arc. The inclined surface of the arc-shaped flow guide 10321 can be arranged to project away from the liquid inlet 1034.This arrangement allows the liquid entering the second segment of the flow channel 1032 through the liquid inlet 1034 to flow smoothly into the first segment of the flow channel 1031. Therefore, the impact of the liquid on the inner wall of the circulation channel 23 is reduced, thus increasing the liquid flow rate.

[00154] In some embodiments of the present disclosure, as illustrated in Figure 25, Figure 27, Figure 29 and Figure 30, the agitator body 10 may have a flow guide structure 40. The flow guide structure 40 may be disposed of at the liquid inlet 1034. One flow guide structure 40 may be provided. A plurality of flow guide structures 40 may also be provided. For example, two flow guide structures of Petition 870250105399, dated 11 / 18 / 2025, page 67 / 100 / 76. Flow guides 40 can be arranged at each liquid inlet 1034. The flow guide structure 40 may extend beyond the circulation channel 23 or may not extend beyond the circulation channel 23. The flow guide structure 40 is located at an upper end of the lower wall 10341 of the liquid inlet 1034. Furthermore, the flow guide structure 40 has a lower end connected to an upper surface of the lower wall 10341 of the liquid inlet 1034.

[00155] The flow guide structure 40 can be constructed in the form of an arc. For example, the flow guide structure 40 can be constructed in the form of a circular arc, or the flow guide structure 40 can be constructed in the form of an elliptical arc. By providing the flow guide structure 40, the flow field pattern at the liquid inlet 1034 can be changed. As a result, there is no large eddy current in the liquid at the liquid inlet 1034. Therefore, the resistance to liquid flow can be reduced. In this way, the liquid inlet volume of the agitator 2 can be increased.

[00156] In some embodiments of the present disclosure, a plurality of circulation channels 23, a plurality of liquid inlets 1034, and a plurality of liquid outlets 1033 are formed. The plurality of circulation channels 23, the plurality of liquid inlets 1034, and the plurality of liquid outlets 1033 are arranged in one-to-one correspondence with each other. For example, two circulation channels 23 may be formed. The two circulation channels 23 may be separated from each other in the circumferential direction of the agitation device 2. In an exemplary embodiment, four, six, or eight circulation channels 23 may be formed. The present disclosure is not limited in this respect. The number of liquid outlets 1033 and the number of liquid inlets 1034 are equal to the number of circulation channels 23.Furthermore, the plurality of circulation channels 23, the plurality of liquid outputs 1033, and the plurality of liquid inputs 1034 are arranged in a one-to-one correspondence. With this... Petition 870250105399, dated 11 / 18 / 2025, page 68 / 100 / 76 provision, the liquid sprayed from agitator 2 can be spread uniformly in the circumferential direction of agitator 2, which is beneficial to balance the detergent content of the liquid around agitator 2. Therefore, it is beneficial to improve the washing effect of cleaning apparatus 1.

[00157] In some embodiments of the present disclosure, as illustrated in Figure 25 and Figure 29, the agitation device 2 may further include a flow guide member 20. The flow guide member 20 may be disposed in the agitation body 10. Furthermore, the flow guide member 20 is adapted to block the liquid exiting the liquid outlet 1033 in order to divert the liquid. In an exemplary embodiment of the present disclosure, at least part of the flow guide element 20 may be disposed above the liquid outlet 1033. When the liquid is sprayed out of the liquid outlet 1033, the liquid is blocked by the flow guide member 20 and thus diverted. In an exemplary embodiment of the present disclosure, the liquid may be sprayed towards the outer radial side of the agitation device 2 due to the blockage by the flow guide element 20.This arrangement can not only increase the coverage area of ​​the liquid discharged from agitator device 2, but also increase the speed (impact force) when the liquid comes into contact with the laundry. Therefore, the liquid discharged from agitator device 2 can come into more sufficient contact with the laundry located in the upper layer of cleaning apparatus 1, which is beneficial for improving the washing effect of cleaning apparatus 1.
