Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular to a pulsator assembly and a clothing processing device having the same. Background Art

[0002] In the prior art, there are mainly two ways of filtering dandruff. One is to set a filter on the inner wall of the washing tub, and use the rotation of the impeller to lift the washing water along the filtering circulation waterway and enter the filter to collect and filter the dandruff. The second is also to set a filter on the inner wall of the washing tub. The difference is that the flow of washing water during washing is used to naturally flow into the filter to filter the dandruff.

[0003] However, the first filtering method requires lifting water into the filtering circulation waterway, so it consumes more energy, and the filtering effect will be worse when washing at a low water level; the second filtering method is passive filtration with low filtration efficiency, especially when running the quick wash program, the filtering effect is greatly reduced, and when washing at a low water level, the contact area between the filter and water becomes smaller, the filtering effect will also be greatly reduced, thereby affecting the working performance of the washing machine.

[0004] In the prior art, in order to solve the above problems, a filter is usually arranged on the bottom wall of the washing tub. However, during the operation of the washing machine, it cannot be guaranteed that the washing water can effectively flow through the filter, thereby reducing the filtering effect. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

Because the filter is arranged at the water inlet, the washing water will first flow through the filter during the water absorption process, that is, it is ensured that the washing water can effectively flow through the filter, so that the washing water can be filtered by the filter to ensure the cleanliness of the washing water.

[0070] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0071] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0072] The impeller assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0073] like Figure 1 As shown, a pulsator assembly 100 according to an embodiment of the present invention includes: a pulsator body 110 , a back plate 120 , a plurality of water guides 140 and a filter 160 .

[0074] Among them, Figure 2 As shown, a water inlet 111 is provided in the middle of the impeller body 110 .

[0075] Combination Figure 1 , Figure 3 and Figure 4 As shown, the back plate 120 is arranged on one side of the impeller body 110 in the thickness direction, and a circumferentially open flow cavity 130 is formed between the back plate 120 and the impeller body 110, and the flow cavity 130 is connected to the water inlet 111. The thickness direction mentioned here can be understood as Figure 3 The up and down directions shown in .

[0076] That is to say, the back plate 120 is arranged on one side of the impeller body 110 in the up and down directions, and a flow cavity 130 is formed between the back plate 120 and the impeller body 110. The flow cavity 130 has a circumferential opening to realize the connection between the flow cavity 130 and the external space, thereby facilitating the discharge of water in the flow cavity 130.

[0077] It should also be noted that the flow cavity 130 formed between the back plate 120 and the impeller body 110 mentioned here can be understood as the flow cavity 130 formed between the entire back plate 120 and the impeller body 110 .

[0078] At the same time, by connecting the flow chamber 130 with the water inlet 111 , the water flowing through the water inlet 111 can flow into the flow chamber 130 , so as to realize water delivery into the flow chamber 130 .

[0079] In summary, water can be delivered to the flow chamber 130 through the water inlet 111 on the impeller body 110, and at the same time, the water in the flow chamber 130 can be discharged through the circumferential opening so that the water in the flow chamber 130 can circulate.

[0080] Combination Figure 1 , Figure 3 and Figure 4 As shown, a plurality of water guides 140 are disposed between the back plate 120 and the impeller body 110 and are arranged in a circumferential direction of a circle, and a flow passage 150 is formed between two adjacent water guides 140. In other words, a plurality of water guides 140 are disposed in the flow chamber 130 and form a flow passage 150 in the flow chamber 130, and because the plurality of water guides 140 are arranged in a circumferential direction of a circle, when the impeller assembly 100 rotates, the plurality of water guides 140 can be used to move the water in the flow chamber 130, so as to drive the water flow in the flow chamber 130 to perform centrifugal rotational motion, so that the water flow in the flow chamber 130 can be smoothly discharged through the circumferential opening of the flow chamber 130, so as to realize that the water in the flow chamber 130 can circulate.

[0081] It should be noted that the circumference mentioned above can be understood as the circumference located in the middle of the impeller body 110. In this way, when multiple water guiding members 140 are arranged circumferentially of the circle, the multiple water guiding members 140 can be evenly distributed on the impeller body 110, thereby ensuring the balance of the impeller body 110 during the rotation process, so as to ensure the working performance of the impeller body 110.

[0082] It should also be noted that the present application sets a back plate 120 on one side in the thickness direction of the impeller body 110, so that when the impeller body 110 rotates, the back plate 120 can be driven to rotate at the same time. At this time, the impeller body 110, the back plate 120 and the water guide member 140 cooperate to realize the water in the flow chamber 130 to be thrown out, so as to form a negative pressure zone in the flow chamber 130, thereby facilitating the forced pumping of water into the flow chamber 130, that is, to enable the water to effectively enter the flow chamber 130 and realize the circulation of water.

[0083] Combination Figure 2 , Figure 3 and Figure 4 As shown, the filter 160 is disposed at the water inlet 111. Thus, when water enters the flow chamber 130 through the water inlet 111, the water can effectively flow through the filter 160, so that the filter 160 can be used to filter the washing water in the laundry processing device 1000 to ensure the cleanliness of the washing water, thereby ensuring the working quality of the laundry processing device 1000.

[0084] It is worth noting that the present application is provided with a back plate 120, so that when the impeller body 110 rotates, the water can be forced to be pumped into the flow chamber 130. In other words, the present application can force the washing water to be sucked into the filter 160, reducing the difficulty of filtering, thereby achieving the purpose of filtering the washing water.

[0085] In addition, the filter 160 is arranged at the water inlet 111, and the filter 160 can also be arranged in the middle of the impeller body 110. In this way, while the filter 160 is supported by the impeller body 110, the structural balance of the impeller assembly 100 can be ensured to ensure the stability of the impeller assembly 100 during rotation, thereby ensuring the working performance of the impeller assembly 100.

[0086] As can be seen from the above structure, the impeller assembly 100 of the embodiment of the present invention is provided with a filter 160 at the water inlet 111 of the impeller body 110, a back plate 120 is provided on one side in the thickness direction of the impeller body 110, and a flow cavity 130 with a circumferential opening is formed between the back plate 120 and the impeller body 110, and a plurality of water guides 140 are provided between the back plate 120 and the impeller body 110. During the rotation of the impeller assembly 100, due to the action of centrifugal force, the back plate 120 and the impeller body 110 can form a structure similar to a centrifugal pump, so as to force the washing water to be sucked into the filter 160 for filtration, thereby ensuring the filtering effect.

[0087] It can be understood that compared with the prior art in which a filter is set on the inner wall of the washing tub, the present application does not need to lift the water; compared with the prior art in which a filter is directly set on the bottom wall of the washing tub, the present application is provided with a back plate 120, which can realize forced suction of the washing water into the filter 160, thereby ensuring that the filter 160 can effectively filter the washing water. At the same time, the washing water can circulate more times in the same time, the filtration efficiency is higher, and the influence of the low water level on the filtration efficiency is avoided.

[0088] In a specific example, through the above-mentioned arrangement, during the rotation of the impeller assembly 100, due to the special centrifugal pump effect formed by the impeller body 110 and the back plate 120, under the action of the water guide 140, centrifugal force is generated, and the water in the flow cavity 130 formed between the impeller body 110 and the back plate 120 will be thrown out to form a negative pressure, thereby causing the flow cavity 130 to generate suction. At this time, the washing water inside the clothing treatment drum 200 is forced to pass through the filter 160, so that the hair mixed in the washing water can be filtered and collected by the filter 160. The filtered and collected water is then discharged into the clothing treatment drum 200 through the circumferential opening of the flow cavity 130 to ensure the cleanliness of the washing water and allow the washing water to circulate.

[0089] The hair debris described here includes but is not limited to fluff, dust, paper scraps and / or hair, etc.

[0090] It should be noted that the pulsator assembly 100 with lint collection function of the present application is not only applicable to ordinary pulsator / agitator type clothing processing device 1000, but also applicable to clothing processing devices 1000 with only a single-layer clothing processing drum 200 (such as Fig. 22 shown), where Fig.21 and Fig. 22 The arrows in FIG. 1 show the flow direction of the wash water during the filtration process.

[0091] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0092] In some embodiments, Figure 1 As shown, the water guide 140 extends radially along the circumference. The circumference here is the circumference surrounded by multiple water guides 140, and the radial direction of the circumference can also be understood as the radial direction of the impeller body 110. By setting the water guide 140 to extend radially along the circumference, the flow channel 150 can extend radially along the circumference, so that the flow channel 150 can be used to guide the washing water in the flow cavity 130 to flow radially along the circumference, so that the water flow in the flow cavity 130 can be smoothly discharged through the circumferential opening of the flow cavity 130, so that the water in the flow cavity 130 can circulate, so as to filter the washing water by the filter 160.

[0093] In some embodiments, Figure 1 As shown, a plurality of water guides 140 diverge radially along the circumference. It can also be understood that two adjacent water guides 140 extend obliquely from the middle to the outside in the radial direction of the impeller body 110 in a direction away from each other, so as to increase the area of ​​the flow passage 150 formed between the two adjacent water guides 140, thereby facilitating rapid and large-scale discharge of the washing water in the flow chamber 130, increasing the number of circulating filtration times of the washing water, and thus improving the filtration efficiency.

[0094] Alternatively, if Figure 1 As shown, the plurality of water guides 140 extend in a straight line along the radial direction of the impeller body 110 , so that the plurality of water guides 140 are formed in a straight line shape in the radial direction of the impeller body 110 , thereby reducing the difficulty of forming the plurality of water guides 140 .

[0095] At the same time, compared with setting multiple water guide members 140 as arc-shaped members, the straight water guide members 140 can ensure that water can be pumped during both forward and reverse rotation of the impeller assembly 100, and the water pumping effect is good, so that the impeller assembly 100 can facilitate the filter 160 to filter the washing water during both forward and reverse rotation, further improving the number of circulation filtration times of the washing water.

[0096] In some embodiments, Figure 1 As shown, the water guide 140 extends radially along the circumference and extends to the outer periphery of the back plate 120, so that the water guide 140 is also formed on the outer periphery of the flow chamber 130, so that the water guide 140 can be used to guide the water discharged from the flow chamber 130 to ensure the water circulation path.

[0097] In some embodiments, in combination Figure 7 and Figure 8 As shown, the radius of the impeller body 110 is R1, and the radius of the back plate 120 is R2, wherein R1-R2≥15mm. That is, the radius of the impeller body 110 is greater than the radius of the back plate 120, and the impeller body 110 exceeds the back plate 120 by at least 15mm, so as to ensure the water rejection performance of the impeller assembly 100, that is, to ensure that during the rotation of the impeller assembly 100, the washing water in the flow chamber 130 can be smoothly thrown out, thereby ensuring the water circulation speed and filtering effect, so as to ensure the working performance of the impeller assembly 100.

[0098] At the same time, the above-mentioned setting can also avoid water absorption noise caused by excessive centrifugal force, that is, it can reduce the noise of the impeller assembly 100 during operation and improve the user experience.

[0099] In some embodiments, one of the back plate 120 and the impeller body 110 is an integral part with the water guide 140, and the other of the back plate 120 and the impeller body 110 abuts against at least part of the water guide 140. That is, when the water guide 140 and one of the back plate 120 and the impeller body 110 are formed as an integral part, at least part of the water guide 140 abuts against the other of the back plate 120 and the impeller body 110, so as to realize that the water guide 140 is disposed between the back plate 120 and the impeller body 110, and ensure the cooperation effect of the water guide 140 with the back plate 120 and the impeller body 110.

[0100] In some embodiments, the back plate 120 and the other of the impeller body 110 have a positioning groove (not shown in the figure), and the water guide 140 cooperates with the positioning groove. What is meant here is that when the water guiding member 140 abuts against the other one of the back plate 120 and the impeller body 110, a positioning groove is provided on the back plate 120 and the impeller body 110, and the water guiding member 140 is fitted in the positioning groove. While achieving the abutment cooperation between the water guiding member 140 and the other one of the back plate 120 and the impeller body 110, the abutment strength and sealing of the water guiding member 140 and the other one of the back plate 120 and the impeller body 110 can be guaranteed. In this way, while the water guiding member 140 can be stably arranged between the back plate 120 and the impeller body 110, it can also be ensured that under the manipulation of the water guiding member 140, the washing water can effectively flow along the flow channel 150 to the circumferential opening of the flow chamber 130, so as to facilitate the discharge of the washing water, thereby facilitating the formation of negative pressure in the flow chamber 130, so as to facilitate the filtering of the washing water by the filter 160.

[0101] In some embodiments, the impeller body 110 and the water guide member 140 are integrated, and a positioning groove is provided on the back plate 120 . The water guide member 140 cooperates with the positioning groove to stop the water guide member 140 against the back plate 120 .

[0102] It should be noted that, compared with the back plate 120, the impeller body 110 has a certain structural strength. By configuring the impeller body 110 and the water guide member 140 as an integrated part, the difficulty of molding the water guide member 140 can be reduced. At the same time, it is also convenient to use the impeller body 110 to support the water guide member 140, thereby improving the position stability of the water guide member 140 and ensuring the working performance of the water guide member 140.

[0103] In some embodiments, reinforcing ribs are provided on the impeller body 110 , which are used to improve the structural strength of the impeller body 110 to extend the service life of the impeller body 110 , and can further reduce the molding difficulty of the water guide member 140 and ensure the position stability of the water guide member 140 .

[0104] In some embodiments, in combination Figure 5 , Figure 6 and Figure 7As shown, the back plate 120 is detachably connected to the impeller body 110 by a fastener 170. In this way, while realizing that the back plate 120 is arranged on one side of the thickness direction of the impeller body 110, the connection difficulty of the back plate 120 and the impeller body 110 can be reduced, the connection efficiency can be improved, and the connection strength of the back plate 120 and the impeller body 110 can be ensured, so that the relative position of the back plate 120 and the impeller body 110 is stable, thereby increasing the structural strength of the flow chamber 130, and facilitating the use of the back plate 120 and the impeller body 110 to support the water guide 140, so as to improve the position stability of the water guide 140, thereby ensuring the working performance of the water guide 140.

[0105] Optionally, the fastener 170 is a fastening bolt or a fastening screw, etc., so as to further reduce the difficulty of connecting the back plate 120 and the impeller body 110.

[0106] In some embodiments, in combination Fig. 9 and Fig.10 As shown, at least one water guide 140 and / or at least one radial extension line of the water guide 140 has a connection hole 141, and at least one fastener 170 cooperates with the connection hole 141. The radial extension line of the water guide 140 mentioned here can be understood as a straight line that is consistent with the extension path of the water guide 140 and is located on the outer periphery of the water guide 140, that is, the connection hole 141 can be provided on at least one water guide 140, can also be provided on the radial extension line of at least one water guide 140, and can also be provided on at least one water guide 140 and the radial extension line of at least one water guide 140 at the same time, so as to achieve the purpose of realizing the detachable connection between the back plate 120 and the impeller body 110 by using the fastener 170.

[0107] It should be noted here that, combined with Figure 5 , Figure 6 and Fig. 9 As shown, when the water guide member 140 and the impeller body 110 are formed as an integral piece, a first matching hole 121 is provided on the back plate 120 which is opposite to the connecting hole 141, and one end of the fastener 170 passes through the first matching hole 121 on the back plate 120 and is matched and connected with the connecting hole 141 on the water guide member 140, thereby realizing a detachable connection between the back plate 120 and the impeller body 110.

[0108] Correspondingly, when the water guide member 140 and the back plate 120 are formed as an integral piece, a second matching hole (not shown in the figure) is provided on the impeller body 110 and is opposite to the connecting hole 141. One end of the fastener 170 passes through the second matching hole on the impeller body 110 and is matched and connected with the connecting hole 141 on the water guide member 140, thereby realizing a detachable connection between the back plate 120 and the impeller body 110.

[0109] Alternatively, if Figure 5As shown, when the water guide 140 and the impeller body 110 are formed as an integral piece, the outer periphery of the back plate 120 is fixedly connected to the water guide 140 via fasteners 170, and the inner periphery of the back plate 120 is fixedly connected to the impeller body 110 via fastening connectors.

[0110] In some embodiments, in combination Figure 5 , Figure 6 and Fig.12 As shown, a plurality of third matching holes 122 are provided in the middle of the back plate 120, and a fixing hole 114 facing the third matching hole 122 is provided on the impeller body 110. The fastening connector passes through the third matching hole 122 on the back plate 120 and is matched and connected with the fixing hole 114 on the impeller body 110 to realize a detachable connection between the back plate 120 and the impeller body 110, thereby making the connection between the back plate 120 and the impeller body 110 stable.

[0111] The fastening connector mentioned here may be a fastening bolt or a fastening screw, etc.

[0112] In summary, when the water guide 140 and the impeller body 110 are formed as an integrated piece, the back plate 120 is not only fixedly connected to the impeller body 110 by the fastener 170, but also fixedly connected to the impeller body 110 by the fastening connector to ensure the connection strength between the back plate 120 and the impeller body 110.

[0113] In some embodiments, in combination Figure 5 and Figure 7 As shown, there are multiple fasteners 170, and multiple fasteners 170 are arranged at intervals in the circumferential direction of the back plate 120. In order to realize the use of fasteners 170 to fix different positions on the back plate 120, thereby improving the connection strength between the back plate 120 and the impeller body 110.

[0114] At the same time, by arranging multiple fasteners 170 at circumferential intervals on the back plate 120, the fixing force at multiple locations of the back plate 120 can be uniform, so that the position of the back plate 120 relative to the impeller body 110 is stable to ensure the working performance of the impeller assembly 100.

[0115] In some embodiments, in combination Fig. 9 , Fig.10 and Fig.12As shown, the plurality of water guides 140 are connected by at least one annular rib 180 extending in the circumferential direction of the circumference. That is, the pulsator assembly 100 includes at least one annular rib 180 extending in the circumferential direction of the circumference, and the plurality of water guides 140 are connected by the annular rib 180, so that the plurality of water guides 140 can support each other, so as to improve the position stability of the plurality of water guides 140, thereby ensuring the working performance of the plurality of water guides 140, that is, ensuring that during the rotation of the pulsator assembly 100, the plurality of water guides 140 can effectively move the washing water in the flow cavity 130 to flow, so as to facilitate the washing water in the flow cavity 130 to be thrown out.

[0116] In some embodiments, in combination Fig. 9 , Fig.10 and Fig.12 As shown, the impeller body 110 and the plurality of water guides 140 are an integral part, and the annular rib 180 is connected to the impeller body 110. Here, it means that when the impeller body 110 and the plurality of water guides 140 are formed as an integral part, the annular rib 180 is connected to the impeller body 110, so that while ensuring that the plurality of water guides 140 can be connected through the annular rib 180, the annular rib 180 can also be supported by the impeller body 110 to improve the position stability of the annular rib 180, thereby facilitating the use of the annular rib 180 to improve the position stability of the plurality of water guides 140.

[0117] At the same time, by connecting the annular rib 180 to the impeller body 110 , the annular rib 180 can also be used to increase the structural strength of the impeller body 110 to enhance the supporting performance of the impeller body 110 and help extend the service life of the impeller body 110 .

[0118] Optionally, the annular rib 180 is an integral part with the impeller body 110. In this way, while the annular rib 180 is connected to the impeller body 110, the connection difficulty of the annular rib 180 and the impeller body 110 can be reduced, and the connection quality of the annular rib 180 and the impeller body 110 can be ensured, thereby improving the position stability of the annular rib 180.

[0119] In some embodiments, in combination Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the other side of the impeller body 110 in the thickness direction has a plurality of water-repelling protrusions 112, which are arranged in the circumferential direction of the circle, and the water-repelling protrusions 112 define a hollow cavity 1121, and the annular ribs 180 are also connected to the cavity wall of the hollow cavity 1121. By arranging a plurality of water-repelling protrusions 112 on the other side in the thickness direction of the impeller body 110, it is possible to respectively arrange the back plate 120 and the plurality of water-repelling protrusions 112 on opposite sides in the thickness direction of the impeller body 110, so that during the rotation of the impeller assembly 100, the plurality of water-repelling protrusions 112 can be used to move the clothes and washing water in the clothes processing drum 200, so as to facilitate the treatment of the clothes.

[0120] At the same time, by connecting the annular rib 180 to the cavity wall of the hollow cavity 1121 , the annular rib 180 is used to support the water-repelling protrusion 112 , so as to improve the structural strength and stability of the water-repelling protrusion 112 , thereby ensuring the working performance of the water-repelling protrusion 112 .

[0121] In addition, by defining the hollow cavity 1121 by the water-repelling protrusion 112, on the one hand, the weight of the impeller body 110 can be reduced, thereby reducing the difficulty of rotating the impeller body 110, and on the other hand, the material used for the impeller body 110 can be reduced to reduce the manufacturing cost of the impeller body 110.

[0122] Alternatively, if Fig.11 As shown, the plurality of water-repelling protrusions 112 extend in a radial straight line along the impeller body 110. This ensures that the plurality of water-repelling protrusions 112 can repel water during both forward and reverse rotation of the impeller assembly 100, and the water-repelling effect is good, so that the impeller assembly 100 can process clothes during both forward and reverse rotation, thereby improving the clothes processing quality of the clothes processing device 1000.

[0123] In some embodiments, in the thickness direction of the impeller body 110, the water guide 140 is located between two adjacent water-repelling protrusions 112. Here, it means that in the thickness direction of the impeller body 110, a water guide 140 is provided between each two adjacent water-repelling protrusions 112, so that the water guide 140 and the water-repelling protrusions 112 are staggered in the thickness direction of the impeller body 110, so as to achieve reasonable utilization of the space on the impeller body 110, and make the structure on the impeller body 110 evenly distributed after the impeller body 110 is formed, so as to ensure that the structure of the impeller body 110 is stable when rotating, and ensure the working performance of the impeller assembly 100.

[0124] It is worth noting that since the water-repelling protrusion 112 defines a hollow cavity 1121, the present application arranges the water guiding member 140 to be located between two adjacent water-repelling protrusions 112, so that water guiding members 140 are provided on both opposite sides of the hollow cavity 1121, and thus the flow channel 150 between some adjacent two water-repelling members 140 can be arranged directly opposite the hollow cavity 1121 to increase the flow rate of the flow channel 150, thereby ensuring that the washing water in the flow cavity 130 can be quickly discharged, so as to increase the number of circulation filtration times of the washing water, thereby improving the filtration efficiency and filtration quality.

[0125] That is to say, the present application can also enable part of the flow channel 150 to be arranged directly opposite to the hollow cavity 1121 by locating the water guide 140 between two adjacent water-repelling protrusions 112, so as to facilitate the rapid removal of washing water.

[0126] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the annular rib 180 has a plurality of flow gaps 181, and the plurality of flow gaps 181 correspond to the plurality of flow channels 150 one by one. That is, the annular rib 180 located in the flow channel 150 is provided with a flow gap 181, and the flow gap 181 is used to avoid washing water, so that the washing water flowing through the annular rib 180 can smoothly flow toward the circumferential opening of the flow chamber 130, that is, to ensure that the washing water in the flow channel 150 can be discharged smoothly, so as to form a negative pressure in the flow chamber 130, thereby ensuring that the washing water can flow to the filter 160 for filtration.

[0127] In some embodiments, Figure 2 As shown, the impeller body 110 is provided with a plurality of flow openings 113, and the flow cavity 130 and the water inlet 111 are connected through the plurality of flow openings 113. This ensures that the water flowing through the water inlet 111 can smoothly flow into the flow cavity 130, so as to achieve the purpose of sending water toward the flow cavity 130 and realize the circulation of water, so that water can be continuously inflowed at the water inlet 111, so as to facilitate the use of the filter 160 to filter the washing water.

[0128] In some embodiments, in combination Figure 7 and Figure 8 As shown, the radius of the back plate 120 is R2, and the maximum distance between the flow port 113 and the center of the impeller body 110 is R3, where R2≥1.5R3. The maximum distance mentioned here can be understood as the distance between the side wall of the flow port 113 away from the center of the impeller body 110 and the center of the impeller body 110.

[0129] Through the above arrangement, the size of the flow chamber 130 can be guaranteed, thereby ensuring the suction force of the flow chamber 130, so as to achieve the speed of water circulation and the filtering effect, thereby improving the filtering quality of washing water.

[0130] In summary, R1-R2≥15mm and R2≥1.5R3, so as to effectively ensure the working performance of the impeller assembly 100.

[0131] In some embodiments, Fig.13 and Fig.14 As shown, the filter 160 includes a filter body 161 and a filter element, a filter cavity 1611 is formed in the filter body 161, the filter cavity 1611 is communicated with the water inlet 111, and the filter element is arranged in the filter cavity 1611. In this way, the washing water flowing into the water inlet 111 can enter the filter cavity 1611, so that the washing water is filtered by the filter element in the filter cavity 1611, thereby ensuring the cleanliness of the washing water and achieving the filtering effect of the filter 160.

[0132] Optionally, the filter element is formed as a filter net, and the filter net is used to filter the washing water, which can reduce the difficulty of filtering and ensure the filtering effect.

[0133] In some embodiments, the filter element is fixedly connected in the filter cavity 1611 to improve the position stability of the filter element, thereby ensuring the filtering effect of the filter element.

[0134] In some embodiments, in combination Fig.13 , Fig.15 and Fig.16 As shown, the filter 160 also includes a switch valve 163, which is movably disposed in the filter chamber 1611 for controlling the opening and closing of the inlet 1612 and the outlet 1613 of the filter chamber 1611. The switch valve 163 is configured to open when water enters the filter chamber 1611 to connect the inlet 1612 and the outlet 1613. That is to say, the filter chamber 1611 has an inlet 1612 and an outlet 1613, and the switch valve 163 can be opened when water enters the filter chamber 1611 to control the inlet 1612 and the outlet 1613 to be connected. Of course, the switch valve 163 can also control the inlet 1612 and the outlet 1613 of the filter chamber 1611 to be disconnected, wherein, when the inlet 1612 and the outlet 1613 are controlled to be connected when water enters the filter chamber 1611, the washing water can effectively enter the filter chamber 1611 through the inlet 1612 and be discharged through the outlet 1613. Since the filter element is arranged in the filter chamber 1611, the filter element can be used to filter the detergent at this time to ensure the cleanliness of the washing water, thereby ensuring the working quality of the clothing processing device 1000.

[0135] In some embodiments, in combination Fig.15 and Fig.16 As shown, the switch valve 163 is formed as a rotating plate, which is configured to open by the impact force of water when water enters the filter chamber 1611 to connect the inlet 1612 and the outlet 1613, thereby controlling the on and off of the filter chamber 1611.

[0136] Furthermore, by providing the on-off valve 163 as a rotating plate, it is possible to simplify the structure of the on-off valve 163.

[0137] In some embodiments, the switch valve 163 is arranged near the inlet 1612 of the filter chamber 1611, and the filter element is arranged near the outlet 1613 of the filter chamber 1611. In this way, while it is convenient to use the switch valve 163 to control the opening and closing of the inlet 1612 and the outlet 1613, it can also avoid the filter element from hindering the rotation of the switch valve 163 and ensure that the filter element can effectively filter the washing water.

[0138] In some embodiments, in combination Fig.17 and Fig.18 As shown, the inlet 1612 and the outlet 1613 each include a plurality of inlets 1612 and a plurality of outlets 1613 , and the plurality of inlets 1612 and the plurality of outlets 1613 cooperate to ensure the flow rate of the washing water, thereby improving the filtering effect of the washing water.

[0139] In some embodiments, in combination Fig.15 and Fig.16 As shown, an elastic member 164 is provided between the switch valve 163 and the filter body 161, and the elastic member 164 is used to drive the switch valve 163 to disconnect the inlet 1612 and the outlet 1613. In this way, when the filter cavity 1611 is not filled with water, the washing water in the filter cavity 1611 can be prevented from entering the clothes treatment drum 200 through the inlet 1612, thereby preventing the hair scraps in the filter cavity 1611 from entering the clothes treatment drum 200, so as to ensure the cleanliness of the clothes treatment drum 200, thereby ensuring the working performance of the clothes treatment device 1000.

[0140] That is to say, the switch valve 163 of the present application connects the inlet 1612 and the outlet 1613 when water enters the filter chamber 1611, and disconnects the inlet 1612 and the outlet 1613 when water does not enter the filter chamber 1611. In this way, while filtering the washing water by using the filter 160, it can also prevent the washing water in the filter chamber 1611 from entering the clothing processing drum 200 through the inlet 1612.

[0141] Optionally, the elastic member 164 is a rectangular spring, and the switch valve 163 is rotatably connected to the rectangular spring. When water enters the filter chamber 1611 and the impact force of the water flow is greater than the driving force of the rectangular spring, the switch valve 163 rotates to connect the inlet 1612 and the outlet 1613 (such as Fig.16 When the filter chamber 1611 is not filled with water, the spring controls the switch valve 163 to rotate to disconnect the inlet 1612 and the outlet 1613 (as shown in FIG. Fig.15 shown).

[0142] Of course, in some other embodiments, the elastic member 164 may also be a torsion spring or other structural member that can generate elastic deformation.

[0143] It should be noted that in other embodiments, the elastic member 164 is not limited to be provided, and the switch valve 163 may also be formed as a one-way valve or a solenoid valve. The one-way valve or the solenoid valve may also control the conduction between the inlet 1612 and the outlet 1613 and prevent hair debris from entering the clothing processing drum 200 from the inlet 1612.

[0144] Optionally, the filter 160 is detachably arranged at the water inlet 111. The filter 160 is detachably connected to the impeller body 110, which reduces the difficulty of assembling the filter 160 and the impeller body 110 and facilitates the removal of the filter 160, thereby facilitating the cleaning of the filter 160, reducing the difficulty of cleaning the filter 160, and ensuring the filtering quality of the filter 160.

[0145] It should be noted that the detachable connection mentioned here can be a snap connection, a buckle connection or a bolt connection, etc.

[0146] In a specific example, through the above-mentioned arrangement, when the impeller assembly 100 rotates to form a negative pressure zone in the flow chamber 130, the washing water outside the filter 160 first flows toward the water inlet 111. Since the filter chamber 1611 is arranged at the water inlet 111, the washing water can enter the filter chamber 1611 through the inlet 1612 of the filter chamber 1611 and impact the switch valve 163, so that the switch valve 163 opens to guide the washing water through the filter chamber 1611, the inlet 1612 and the outlet 1613, so that the washing water can flow toward the outlet 1613, thereby facilitating the use of the filter element to filter the washing water. The filtered washing water flows to the outlet 1613 of the filter chamber 1611. After being discharged from the outlet 1613, the washing water will enter the flow chamber 130 through the flow port 113, and then the flow chamber 130 is thrown out by the rotation of the impeller assembly 100 to form a negative pressure zone in the flow chamber 130. This cycle is repeated to achieve the purpose of filtering the washing water and ensure the filtering effect.

[0147] The laundry treating apparatus 1000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0148] like Figure 19-22 As shown, a laundry processing device 1000 according to an embodiment of the present invention includes: a laundry processing drum 200 and a pulsator assembly 100 .

[0149] Among them, Fig.19 and Fig. 20 As shown, the pulsator assembly 100 is the aforementioned pulsator assembly 100, and the pulsator assembly 100 is rotatably disposed in the clothing processing drum 200, and the specific structure of the pulsator assembly 100 is not described again.

[0150] It should be noted that, by rotatably arranging the impeller assembly 100 in the clothing processing drum 200, the rotation of the impeller assembly 100 can be controlled during the operation of the clothing processing device 1000, so that the rotation of the impeller assembly 100 drives the clothes in the clothing processing drum 200 to be turned over, so that the clothes and the clothes and the wall of the clothing processing drum 200 can continuously rub against each other, so as to achieve the purpose of cleaning the clothes.

[0151] In addition, since the clothes processing device 1000 adopts the aforementioned impeller assembly 100, when the impeller assembly 100 rotates, the washing water can be forcibly sucked into the filter 160 to achieve the purpose of filtering the washing water and ensure the working quality of the clothes processing device 1000.

[0152] That is to say, it can be seen from the above structure that the clothing processing device 1000 of the embodiment of the present invention, by adopting the aforementioned impeller assembly 100, can realize the filtering treatment of washing water by using the impeller assembly 100 and ensure the filtering effect to ensure the cleanliness of the washing water, thereby ensuring the clothing processing effect of the clothing processing device 1000 on the clothes.

[0153] In some embodiments, Fig.19 and Fig. 20 As shown, the clothing processing device 1000 further includes a driving member 300 , which is connected to the pulsator assembly 100 and is used to drive the pulsator assembly 100 to rotate, thereby ensuring the working performance of the pulsator assembly 100 and reducing the difficulty of controlling the pulsator assembly 100 .

[0154] Optionally, the driving member 300 is a rotary motor.

[0155] Alternatively, if Fig.19 , Fig. 20 and Fig.21 As shown, the laundry processing drum 200 includes an inner drum 210 and an outer drum 220 , the inner drum 210 is disposed in the outer drum 220 and can rotate relative to the outer drum 220 , and the pulsator assembly 100 is rotatably disposed in the inner drum 210 .

[0158] like Figure 1 As shown, the pulsator assembly 100 includes a pulsator body 110 , a back plate 120 , twelve water guides 140 and a filter 160 .

[0159] Among them, combined Figure 2 and Fig. 9 As shown, the middle part of the impeller body 110 has a water inlet 111 and six flow ports 113 , and the upper side of the impeller body 110 in the thickness direction has six water-repelling protrusions 112 , which are arranged circumferentially of a circle and define a hollow cavity 1121 .

[0160] Combination Figure 1 , Figure 3 and Figure 7 As shown, the back plate 120 is detachably connected to the lower side of the impeller body 110 in the thickness direction through six fasteners 170, the radius of the impeller body 110 is R1, the radius of the back plate 120 is R2, R1-R2≥15mm, the six fasteners 170 are arranged at intervals in the circumferential direction of the back plate 120, the back plate 120 is provided with a positioning groove, and a circumferentially open flow cavity 130 is formed between the back plate 120 and the impeller body 110, the flow cavity 130 is connected to the water inlet 111 through six flow ports 113, the maximum distance between the flow port 113 and the center of the impeller body 110 is R3, R2≥1.5R3.

[0161] Combination Figure 1 , Fig. 9 and Fig.10 As shown, the water guiding member 140 and the impeller body 110 are an integral part, and twelve water guiding members 140 are arranged between the back plate 120 and the impeller body 110. The twelve water guiding members 140 are arranged in the circumferential direction of a circle and extend radially along the circumference. The twelve water guiding members 140 are connected by annular ribs 180 extending in the circumferential direction of the circle. The annular ribs 180 are connected to the impeller body 110 and the cavity wall of the hollow cavity 1121. The annular ribs 180 have flow notches 181. A flow channel 150 is provided between two adjacent water guiding members 140, and the flow notches 181 are connected to the flow channels 150 in a one-to-one correspondence.

[0162] like Fig.10 As shown, a portion of the water guide 140 has a connecting hole 141 , and the fastener 170 cooperates with the connecting hole 141 .

[0163] Combination Fig.13 , Fig.14 and Fig.15As shown, the filter 160 includes a filter body 161, a filter element and a switch valve 163. The filter body 161 is arranged at the water inlet 111. A filter chamber 1611 is formed in the filter body 161. The filter chamber 1611 is communicated with the water inlet 111. The filter element is arranged in the filter chamber 1611. The switch valve 163 is movably arranged in the filter chamber 1611 and an elastic member 164 is provided between the filter body 161. The switch valve 163 is used to control the opening and closing of the inlet 1612 and the outlet 1613 of the filter chamber 1611. The switch valve 163 is configured to open when water enters the filter chamber 1611 to connect the inlet 1612 and the outlet 1613. The elastic member 164 is used to drive the switch valve 163 to disconnect the inlet 1612 and the outlet 1613.

[0164] Through the above arrangement, during the specific operation of the clothing treatment device 1000, the impeller assembly 100 is controlled to rotate. When the impeller assembly 100 rotates, the water-repelling protrusion 112 drives the washing water in the clothing treatment drum 200 to rotate, and the water guide 140 drives the water flow in the flow chamber 130 to perform centrifugal rotation. At this time, the water flow in the flow chamber 130 can return to the clothing treatment drum 200 through the circumferential opening of the flow chamber 130, and the flow chamber 130 forms a negative pressure area, so that a pressure difference is formed on both sides of the impeller body 110, so that the washing water in the clothing treatment drum 200 will be sucked into the impeller assembly 100 (such as Fig.21 and Fig. 22 As shown in the figure, since the filter 160 is arranged at the water inlet 111, the washing water sucked into the impeller assembly 100 first enters the filter 160 and impacts the switch valve 163, so that the switch valve 163 opens to guide the water through the filter chamber 1611 and the inlet 1612 and the outlet 1613, so as to allow the water flow carrying hair debris to enter the filter chamber 1611, so as to facilitate the filtering treatment of the washing water by the filter element.
