[0022] A washing drum, the washing drum including a bottom cover and a peripheral sidewall; the bottom cover is disposed at one axial end of the peripheral sidewall; and a water spray structure as described above;

[0023] The main body is fixedly connected to the peripheral wall of the washing drum; the bottom cover is provided with a third clearance hole, the water injection pipe head passes through the third clearance hole, and the water injection pipe head is fixedly connected to the bottom cover.

When the wash water enters the washing drum, it has an initial velocity in the direction of drum rotation, enriching the water flow pattern. Compared to existing technologies, this results in stronger rinsing power, less or no detergent residue, and a higher washing efficiency. Attached Figure Description

[0047] Detailed Implementation

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0050] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0052] After the main wash stage of the garment processing equipment is completed, one or more rinses are required to remove the detergent from the clothes. In existing technology, the rotation of the washing drum drives the water flow to mechanically interact with the clothes, thus separating the detergent from the clothes and into the wash water. However, in this method, the water flow is powered solely by the rotation of the washing drum, resulting in limited water flow patterns and a technical problem of incomplete detergent rinsing.

[0053] Therefore, such as Figure 1 As shown, this application provides a water spray structure. Figure 1 and Figure 2 As shown, the water spray structure is located on the washing drum 10. Figure 1 and 2 As shown, the water spray structure includes:

[0054] A lifting rib 30 includes a body 310 and a water inlet box 320 disposed within the body 310; the body 310 is fixed to the peripheral side wall 110 of the washing drum 10; the water inlet box 320 has a water inlet cavity S1; the body 310 or the water inlet box 320 has a drain outlet 330 communicating with the water inlet cavity S1; the drain outlet 330 is used to spray washing water into the washing drum 10; and

[0055] Water injection pipe head 410 is fixedly connected to the lifting rib 30 and communicates with the water inlet cavity S1 for injecting water into the water inlet cavity S1; the water injection pipe head 410 is used to connect to the water pipe 70.

[0056] In the technical solution of this application embodiment, the body 310 of the lifting rib 30 is used to fix the peripheral sidewall 110 of the washing drum 10 so as to fix the water spray structure to the washing drum 10; the body 310 is provided with a water inlet box 320, and the water inlet box 320 is provided with a water inlet cavity S1; the body 310 or the water inlet box 320 is provided with a drain outlet 330 communicating with the water inlet cavity S1 so as to spray washing water into the washing drum 10. The water injection pipe head 410 is fixedly connected to the lifting rib 30 and communicates with the water inlet cavity S1 for injecting water into the water inlet cavity S1. Water inlet nozzle 410 connects to water pipe 70 to inject water into water inlet chamber S1, allowing drain outlet 330 to spray washing water into washing drum 10, directly applying water to the clothes inside the washing drum 10. During the rinsing stage, the washing drum 10 rotates, and water is injected into water inlet chamber S1 through water inlet nozzle 410. Washing water is then sprayed from drain outlet 330 into washing chamber S2. Because the lifting ribs 30 are located on the peripheral wall 110 of the washing drum 10, the sprayed water has an initial velocity, directly rinsing the clothes and mixing with the water already inside the washing drum 10, enriching the water flow pattern and providing strong force to act on the clothes, causing them to expel detergent. When the washing water enters the washing drum 10, it has an initial velocity in the direction of rotation of the washing drum 10, enriching the water flow pattern. Compared to existing technologies, this results in stronger rinsing force on clothes, less or no detergent residue, and a higher washing efficiency.

[0057] In some embodiments, the water inlet housing 320 and the main body 310 may be two separate parts. The water inlet housing 320 is fixed inside the main body 310 by fasteners such as threaded parts and snap-fit ​​parts. The water inlet housing 320 is provided with a drain outlet 330. The main body 310 is provided with a relief opening corresponding to the drain outlet 330 to expose the drain outlet 330 so that washing water can be sprayed into the washing chamber S2.

[0058] In some embodiments, at least a portion of the water inlet box 320 can be integrally formed with the body 310; that is, at least a portion of the body 310 can be used to form the water inlet cavity S1; in this structure, a drain outlet 330 is formed on the body 310, and the drain outlet 330 communicates with the water inlet cavity S1. Further, since it is quite difficult to integrally form the water inlet box 320 with the sealed water inlet cavity S1 on the body 310, in some embodiments, the water inlet cavity S1 formed on the body 310 has an opening O, which can be sealed by the peripheral sidewall 110 when the lifting rib 30 is engaged with the peripheral sidewall 110.

[0059] In some embodiments, the water inlet head 410 may be a threaded water pipe 70 connector, which mates with the water inlet housing 320 to introduce water into the water inlet chamber S1. The water inlet head 410 may also be a flange connector, etc.

[0060] Furthermore, since the lifting rib 30 needs to fit with the peripheral wall 110, and there are some gaps in the fit, the sealing of the water inlet cavity S1 by the peripheral wall 110 places requirements on the fit between the two and the shape of the opening O. Therefore, this method presents higher difficulties and costs in assembly and parts manufacturing. Therefore, as an alternative to the above embodiment, such as... Figure 3 , Figure 4 and Figure 5 As shown, the water inlet box 320 includes a box wall 321 and a box cover 322. The box wall 321 is integrally formed with the body 310 and has a cavity with an open opening O. This structure is relatively easy to manufacture on the body 310 of the lifting rib 30 and can be manufactured through molding. By setting the cover at the open opening O and sealing the open opening O, the cavity becomes a sealed water inlet cavity S1. This does not interfere with the fit between the lifting rib 30 and the peripheral wall 110. There are no restrictions on the shape design of the open opening O, and the assembly structure between the lifting rib 30 and the peripheral wall 110 can use existing structures. The difficulty in manufacturing and assembling the parts is significantly reduced, and the cost is lower.

[0061] As an optional embodiment of the above embodiments, the box cover 322 and / or the box wall 321 are provided with sealing grooves, and the sealing grooves are arranged around the opening O. Figure 6As shown, a sealing groove is provided on the covering surface (the side facing the box wall 321) of the lid 322. In some other embodiments, the sealing groove may also be provided on the lid 322. In some other embodiments, both the lid 322 and the box wall 321 are provided with sealing grooves; these two sealing grooves are staggered. The water inlet box body 320 also includes a first sealing member 323, which is disposed in the sealing groove, and the opposite sides of the first sealing member 323 abut against the lid 322 and the box wall 321 respectively. In this embodiment, the first sealing member 323 is provided in the sealing groove, thereby sealing the water inlet chamber S1.

[0062] like Figure 6 As shown, the edge protrusion at the opening O of the water inlet box 320 extends into the sealing groove, causing the first seal 323 to be in a compressed state, thereby improving the reliability of the seal.

[0063] As an optional implementation of the above embodiments, such as Figure 4 and Figure 5 As shown, the water inlet box 320 is provided with a limiting post 316, which abuts against the side of the box cover 322 facing away from the box wall 321. In an embodiment, the limiting post 316 can be configured to snap back, abutting against the side of the box cover 322 facing away from the box wall 321, so that the box cover 322 is securely placed on the opening O, and can apply pressure to the first sealing member 323 to ensure a reliable seal. In an embodiment, there can be multiple limiting posts 316, which are spaced apart around the box wall 321. And / or

[0064] The box wall 321 is provided with a first positioning structure 312, and the box cover 322 is provided with a second positioning structure 324. The first positioning structure 312 and the second positioning structure 324 cooperate with each other. In some embodiments, one of the first positioning structure 312 and the second positioning structure 324 can be a positioning post, and the other can be a positioning hole. The positioning post and the positioning hole cooperate to pre-position the box cover 322, which can play a role in preventing mistaken positioning. In some embodiments, both the first positioning structure 312 and the second positioning structure 324 include fixing holes. The fixing holes can be connected by a connector to fix the box cover 322 to the water inlet box body 320.

[0065] As an optional implementation of the above embodiments, in the axial direction of the water inlet head 410, the width of the water inlet cavity S1 gradually decreases or tapers away from the water inlet head 410. In this embodiment, after the washing water enters the water inlet cavity S1 through the water inlet head 410, the cross-sectional area of ​​the water inlet cavity S1 gradually or tapers away due to the gradual or step-narrowing width of the water inlet cavity S1, which helps to increase the water pressure and thus improve the flushing force.

[0066] For example, in some embodiments, the width of the water inlet cavity S1 gradually decreases linearly in the direction away from the water inlet pipe head 410.

[0067] For example, such as Figure 1 and Figure 3 As shown, in some embodiments, the water inlet chamber S1 has multiple sequentially connected cavities of different widths, and the width of the cavities decreases sequentially in the direction away from the water injection pipe head 410. For example, the water inlet chamber S1 has three cavities, which are sequentially designated as a first cavity S11, a second cavity S12, and a third cavity in the direction away from the water injection pipe head 410; the first width of the first cavity S11 is greater than the second width of the second cavity S12, and the second width of the second cavity S12 is greater than the third width of the third cavity. In this embodiment, the width direction of the water inlet chamber S1 is perpendicular to the axial direction of the water injection pipe head 410.

[0068] like Figure 1 and Figure 3 As shown, in an optional embodiment of the above example, the water inlet chamber S1 has a first chamber S11 and a second chamber S12, which are connected. The first width of the first chamber S11 is greater than the second width of the second chamber S12. The water injection head 410, extending into the water inlet chamber S1, is located within the first chamber S11. In this embodiment, the water injection head 410 extends at least partially into the first chamber S11, allowing washing water to be directly injected into it. Since the second width of the second chamber S12 is smaller than the first width of the first chamber S11, the water pressure increases, thereby increasing the water jet pressure and enhancing the scouring force of the water flow, which helps to squeeze out the detergent from the clothes.

[0069] As an optional implementation of the above embodiments, Figure 1 As shown, there are multiple drain outlets 330, which are spaced apart on the lifting ribs 30. In this embodiment, the drain outlets 330 are spaced apart on the lifting ribs 30, which can spray water from different positions and form different water flows in the washing chamber S2, thereby enriching the water flow pattern in the washing chamber S2 and improving the washing ratio.

[0070] For example, in some embodiments, the drain outlet 330 can be configured as a ring array; for example, in some embodiments, the drain outlet 330 can be configured as a linear array.

[0071] As an optional implementation of the above embodiments, at least two of the plurality of drain outlets 330 are configured to discharge water in different directions. In this embodiment, having at least two of the drain outlets 330 discharge water in different directions can increase the coverage area of ​​the water flow, allowing for direct rinsing of multiple garments during the rinsing stage and increasing the probability of direct contact with detergent during the washing stage, thereby improving the washing efficiency.

[0072] In some embodiments, the water outlet direction of the drain 330 is the velocity direction of the water as it exits the drain 330; for example, in some embodiments, the water outlet direction of some drains 330 is parallel to the radial direction of the washing drum 10 (the water flow sprays towards the center of the washing drum 10); in some embodiments, the water outlet direction of some drains 330 may have a radial component and a component in the rotation direction of the washing drum 10 (the water flow sprays towards the center of the washing drum 10 and towards the side in the rotation direction); in some embodiments, the water outlet direction of some drains 330 may have a radial component and a circumferential component in the washing drum 10 (the water flow sprays towards the center of the washing drum 10 and towards the side in the axial direction).

[0073] As an optional implementation of the above embodiments, Figure 1 As shown, the drain outlets 330 are arranged at intervals in a preset direction, which has a component along the axial direction of the water inlet head 410 or is parallel to the axial direction of the water inlet head 410. In an embodiment, the drain outlets 330 are arranged at intervals along the preset direction, and this preset direction has a component along the axial direction of the water inlet head 410 or is parallel to the axial direction of the water inlet head 410. Thus, drain outlets 330 are provided at different positions along the axial direction of the water inlet head 410, so that water streams can be sprayed at different positions along the axial direction of the water inlet head 410. For a drum washing machine, the water streams sprayed from the drain outlets 330 at different positions along the axial direction of the water inlet head 410 can form water columns spaced apart in the depth direction (front-back direction), allowing direct rinsing of clothes at different depths.

[0074] In this embodiment, the axial direction of the water inlet head 410 is parallel to the axial direction of the rotating shaft 20, which is used to drive the washing drum 10 to rotate.

[0075] As an optional implementation of the above embodiments, the water outlet direction of the drain 330 has a radial component in the washing drum 10. In embodiments, the water outlet direction of the drain 330 is the velocity direction of the water as it exits the drain 330; for example, in some embodiments, the water outlet direction of some drains 330 is parallel to the radial direction of the washing drum 10 (the water flow is sprayed towards the center of the washing drum 10); in some embodiments, the water outlet direction of some drains 330 may have a radial component and a component in the rotation direction of the washing drum 10 (the water flow is sprayed towards the center of the washing drum 10 and towards the side in the rotation direction); in some embodiments, the water outlet direction of some drains 330 may have a radial component and a circumferential component in the washing drum 10 (the water flow is sprayed towards the center of the washing drum 10 and towards the side in the axial direction). Setting the water outlet direction of the drain 330 to have a radial component in the washing drum 10 means that the water flow is directed towards the radial edge of the washing drum 10 and towards the interior.

[0076] As an optional implementation of the above embodiments, such as Figure 1 As shown, the washing drum 10 has a peripheral sidewall 110; the lifting rib 30 is mounted on the peripheral sidewall 110; the lifting rib 30 has a boss wall 313, which is the cavity wall of the water inlet chamber S1; the boss wall 313 is disposed away from the peripheral sidewall 110; the boss wall 313 has a water spray surface, and the drain outlet 330 penetrates the boss wall 313 from the water spray surface. In some embodiments, the lifting rib 30 has a boss wall 313 and a first sidewall 314 and a second sidewall 315 in the circumferential direction of the washing drum 10. The first sidewall 314 and the second sidewall 315 abut against the peripheral sidewall 110, and the side of both away from the peripheral sidewall 110 is connected by the boss wall 313. The water spray surface and the peripheral sidewall 110 are spaced apart. The drain outlet 330 passes through the boss wall 313 from the water spray surface to connect to the water inlet chamber S1, so that water can be sprayed into the washing chamber S2.

[0077] As an optional implementation of the above embodiments, such as Figure 4 As shown, the main body 310 has a bottom shell 311, which has a first clearance hole 3111; the water inlet box 320 has a second clearance hole. The water injection pipe head 410 passes through the first clearance hole 3111 and the second clearance hole, extending at least partially into the water inlet cavity S1. A second sealing member 420 is fitted onto the water injection pipe head 410, and the second sealing member 420 is interference-fitted with the second clearance hole. In an embodiment, the water injection pipe head 410 passes from outside the main body 310 through the first clearance hole 3111 into the lifting rib 30, and through the second clearance hole into the water inlet cavity S1, extending partially into the water inlet cavity S1 to inject washing water into the water inlet cavity S1. A second sealing element 420 is fitted onto the water injection pipe head 410, and the water injection pipe head 410 is provided with a first limiting protrusion 412 and a second limiting protrusion 413 spaced apart. The two ends of the second sealing element 420 in the axial direction are axially positioned by the first limiting protrusion 412 and the second limiting protrusion 413. The second sealing element 420 is interference-fitted with the second clearance hole to achieve a sealing effect.

[0078] Figure 1 and Figure 7 As shown in the illustration, this application also proposes a washing drum assembly 1, which includes a washing drum 10 and a water spray structure. The water spray structure employs some or all of the embodiments described above. Figure 1 As shown, the washing drum 10 includes a bottom cover 120 and a peripheral sidewall 110; the bottom cover 120 is disposed at one axial end of the peripheral sidewall 110; wherein, the body 310 is fixedly connected to the peripheral sidewall 110 of the washing drum 10. Figure 9 and Figure 10 As shown, the bottom cover 120 is provided with a third clearance hole 122, the water injection pipe head 410 passes through the third clearance hole 122, and the water injection pipe head 410 is fixedly connected to the bottom cover 120.

[0079] In the technical solution of the embodiment, the main body 310 and the peripheral side wall 110 of the washing drum 10 are fixed using a structure in the prior art, such as the hook on the main body 310 being hooked onto the hook interface of the peripheral side wall 110. The fixing between the bottom cover 120 and the peripheral side wall 110 also adopts a solution in the prior art.

[0080] The water inlet nozzle 410 extends from the outside of the bottom cover 120 to the inside of the bottom cover 120 (in the washing chamber S2) through the third clearance hole 122. The buckle 411 on the water inlet nozzle 410 is snapped upside down onto the inside of the bottom cover 120, with the buckling surface 4111 abutting against the inside of the bottom cover 120. The water inlet nozzle 410 also has a third limiting protrusion 414, which abuts against the outside of the bottom cover 120, thus securing it to the bottom cover 120. The buckle 411 is elastic; after deforming through the third clearance hole 122, it returns to its original shape and abuts against the inside of the bottom cover 120.

[0081] In some embodiments of the technical solution, combined with Figure 4 and Figure 8 As shown, the bottom shell 311 of the lifting rib 30 abuts against the inside of the bottom cover 120.

[0082] As an optional embodiment of the above embodiments, there are multiple lifting ribs 30, which are arranged at intervals along the circumference of the washing drum 10; there are multiple water pipes 70; each water pipe 70 is connected to a water inlet cavity S1 of one of the lifting ribs 30. In some embodiments, there are three lifting ribs 30, each of which has a water inlet cavity S1; each water pipe 70 is connected to one water inlet cavity S1. In this way, when water is introduced, the three lifting ribs 30 spray water into the washing cavity S2 at different positions, which can directly rinse the clothes during the rinsing stage and increase the probability of direct mixing with detergent during the washing stage. For example, as Figure 9 As shown, the bottom cover 120 of the washing drum 10 has three mounting areas 121 for lifting ribs 30, with the lifting ribs 30 respectively located within these mounting areas 121. The three lifting ribs 30 are evenly distributed. In this way, when water enters, the water flow can be sprayed from three different circumferential positions, resulting in a rich water flow pattern.

[0083] This application also proposes a garment processing device, which further includes a drive assembly and a washing drum assembly 1. The drive assembly includes a rotating shaft 20 and a support frame 50; the rotating shaft 20 is fixedly connected to the support frame 50; the rotating shaft 20 is provided with a water inlet channel 21 for connecting to a washing water source; the support frame 50 is fixedly connected to the washing drum 10; and a water pipe 70 connects the water inlet channel 21 and the water injection head 410.

[0084] As an optional embodiment of the above embodiments, the washing drum assembly 1 further includes a support frame 50, which is connected to the rotating shaft 20 and the washing drum 10; the water pipe 70 is fixedly connected to the support frame 50. In this embodiment, the support frame 50 can be a tripod (three support arms 510), or a support frame 50 with other numbers of support arms 510. The ends of the support arms 510 away from the rotating shaft 20 are fixedly connected to the washing drum 10, and the fixing structure adopts existing technology. The support frame 50 also includes an annular disc 520, which is fixedly connected to the rotating shaft 20, and the fixing structure adopts existing technology. The support arms 510 are spaced apart along the axial direction of the annular disc 520.

[0085] In this embodiment, the water pipe 70 has a certain extension length because it needs to guide water flow from the rotating shaft 20 into the lifting rib 30 away from the rotating shaft 20. Therefore, to prevent the water pipe 70 from falling off during rotation, it is fixed to the support arm 510 to improve its stability. Since the support arm 510 extends radially, and the water pipe 70 extends approximately radially, the water pipe 70 is fixed to the support arm 510. In some embodiments, the water pipe 70 can be fixed to the support arm 510 using clips. Multiple clips can be used to securely fix the water pipe 70. In some embodiments, the support arm 510 has a locking groove into which at least part of the water pipe 70 is engaged.

[0086] In some embodiments of this application, the fixing structure 720 can fix the water pipe 70 at or near the mid-span to the support frame 50. In other embodiments, multiple fixing structures 720 can be provided, and the multiple fixing structures 720 are arranged at intervals along the extension direction of the water pipe 70 to fix multiple positions of the water pipe 70 to the support frame 50.

[0087] As an optional implementation of the above embodiments, the fixing structure 720 includes a connecting body and a connecting member. Figure 14 and Figure 15As shown, the support frame 50 is provided with a first connecting hole, and the connecting body is provided with a second connecting hole 721; the connecting body is connected to the water pipe 70; the connector connects the first connecting hole and the second connecting hole 721. In the technical solution of this application embodiment, the connecting body of the fixing structure 720 is connected to the water pipe 70; the first connecting hole on the support frame 50 and the second connecting hole 721 on the connecting body are connected by the connector, thereby fixing the connecting body to the support frame 50.

[0088] As an optional implementation of the above embodiments, the axial directions of the first connecting hole and the second connecting hole 721 are parallel to the axial direction of the rotating shaft 20; or the axial directions of the first connecting hole and the second connecting hole 721 are parallel to the rotation direction of the rotating shaft 20. In some embodiments, combined with Figure 14 As shown, the axial direction of the second connecting hole 721 is perpendicular to the axial side surface 511 on the support frame 50 along the axial direction of the rotating shaft 20, that is, the opening of the second connecting hole 721 is located on the axial side surface 511. In some other embodiments, such as Figure 15 As shown, the axial direction of the second connecting hole 721 is perpendicular to the circumferential side surface 512 on the support frame 50 in the rotation direction of the rotating shaft 20, that is, the opening of the second connecting hole 721 is located on the circumferential side surface 512.

[0089] In some embodiments, the fixing structure 720 has multiple components; wherein the axial directions of the second connecting holes 721 on the connecting bodies of at least two fixing structures 720 are different from each other; there are two fixing structures 720, one of which has a second connecting hole 721 on its connecting body parallel to the axial direction, and the other is parallel to the rotation direction of the rotating shaft 20. In this structure, the water pipe 70 is constrained in both the axial and rotational directions, further improving the robustness of the water pipe 70.

[0090] As an optional implementation of the above embodiments, such as Figure 2 As shown, the water pipes 70 include multiple pipes, which are arranged at intervals along the circumference of the rotating shaft 20; the support frame 50 includes multiple support arms 510, which are arranged at intervals along the circumference of the rotating shaft 20; each water pipe 70 is fixed to at least one support arm 510 by the fixing structure 720. In this embodiment, in order to achieve uniform distribution of detergent in the washing chamber S2 and to rinse clothes in different areas, multiple water pipes 70 are provided, and the water pipes 70 are arranged at intervals along the circumference of the rotating shaft 20, so as to guide the washing water to different positions in the washing chamber S2. Each water pipe 70 is fixed to a support arm 510. In this embodiment, the support frame 50 is usually a tripod. Therefore, three water pipes 70 are provided, and each water pipe 70 is fixed to one of the three support arms 510 of the corresponding tripod.

[0091] like Figure 14 and Figure 15 As shown, the support frame 50 includes a receiving groove S5, the opening of which faces the rotation direction of the rotating shaft 20 or the opposite direction of rotation of the rotating shaft 20; the water pipe 70 is at least partially received within the receiving groove S5. In an embodiment, the support frame 50 has a recessed receiving groove S5 on one side of the rotation direction or on the opposite side of the rotation direction, so that the water pipe 70 can be at least partially placed into the receiving groove S5, reducing the space occupied by the water pipe 70.

[0092] In some embodiments, the receiving groove S5 is provided with a limiting rib, the shape of which is adapted to the water pipe 70, so that the water pipe 70 can be limited by the limiting rib, thereby further improving the stability of the water pipe 70.

[0093] In some technical solutions of the embodiments of this application, the tube can be either an elastic hose or a rigid tube; the elastic hose is such as EPDM. The rigid tube can be made by blow molding or is a metal tube, such as stainless steel.

[0094] The water inlet via the rotating shaft 20 is one type of water inlet method for clothing processing equipment. In the prior art, the water inlet via the rotating shaft 20 enters from the central area of ​​the washing drum 10; because the water inlet position is close to the central area, this water inlet method has the technical problem of low washing efficiency for clothes; the main problems are: uneven dissolution of detergent and limited rinsing ability for clothes.

[0095] Therefore, this application provides a garment processing device that introduces washing water from the rotating shaft 20 through a water pipe 70 onto the lifting ribs 30 on the washing drum 10, and then sprays it into the washing chamber S2 through the drain outlet 330 on the lifting ribs 30. Because the lifting ribs 30 are far from the center area, the sprayed water flow gains a greater speed due to the rotation of the rotating shaft 20, and the lifting ribs 30 rotate with the washing drum 10, allowing the sprayed water flow to circulate around the washing chamber S2. During the rinsing stage, the greater speed provides a powerful wash for the garments, and the water flow circulating around the washing chamber S2 ensures even contact between the water and the garments, reducing detergent residue and improving the cleanliness of the garments. During the washing stage, the sprayed water flow circulating around the washing chamber S2 allows for sufficient contact with the detergent for complete dissolution, and the initial force of the water flow allows for diffusion, resulting in a uniform detergent concentration.

[0096] For example, during the rinsing stage, the rotating shaft 20 rotates at a certain speed. At this time, the washing water is introduced into the lifting ribs 30. The sprayed water will gain a greater speed with the help of the rotation of the rotating shaft 20, so as to vigorously wash the clothes. The lifting ribs 30 will rotate with the washing drum 10, and the sprayed water can surround the washing chamber S2, so that the water can come into even contact with the clothes, reduce detergent residue, and help the clothes to be flushed by the water flow during rinsing to remove the detergent and improve the cleanliness of the clothes.

[0097] In addition, during the washing stage, detergent is added to the washing chamber S2 in a certain way (manually or intelligently). The rotating shaft 20 rotates at a certain speed, at which time the washing water is introduced into the lifting rib 30, and the sprayed water can surround the washing chamber S2, so that the water can fully contact the detergent to fully dissolve the detergent. With the help of the initial force of the water flow, it can spread, so that the concentration of detergent is uniform.

[0098] It should be noted that the lifting rib 30 is a key component in the garment processing equipment for realizing garment washing. It can drive the clothes to rotate from bottom to top, and the continuous rotation of the washing drum 10 enables the lifting rib 30 to tumble the clothes up and down. The lifting rib 30 is set on the peripheral side wall 110 of the garment processing equipment and extends along the axial direction of the washing drum 10.

[0099] In some embodiments, the water outlet connector 710 of the water pipe 70 is sealed to the rotating shaft 20.

[0100] In some other embodiments, the garment processing device further includes a water distribution box 60. The water distribution box 60 is fixedly connected to the support frame 50 and has a water distribution cavity S4, which communicates with the water inlet channel 21. The water distribution box 60 is provided with at least two water outlets, which communicate with the water distribution cavity S4. The at least two water outlets are used to connect different positions of the washing chamber S2 of the washing drum 10.

[0101] In the technical solution of this application embodiment, the water inlet channel 21 of the rotating shaft 20 is connected to the water distribution chamber S4 of the water distribution box 60. The water distribution chamber S4 has at least two water outlets, which can divert the water flow entering the water inlet channel 21 to at least two water outlets, so as to distribute the water to different positions in the washing chamber S2, so that the concentration of laundry detergent in the washing chamber S2 is uniform, and the clothes in different positions can be rinsed to reduce laundry detergent residue and improve the washing ability of the clothes processing equipment.

[0102] In some embodiments, the water distribution box 60 may include a box body and a water inlet provided on the box body, the water inlet being sealed to the outlet of the water inlet channel 21 of the rotating shaft 20. The box body may be fixed to the support frame 50 by threaded fittings.

[0103] In other embodiments, the water distribution cavity S4 has an opening; the support frame 50 covers the opening and seals it. In some embodiments, the water distribution cavity S4 has an opening, the support frame 50 covers the opening and seals it, thus making the water distribution cavity S4 a sealed cavity.

[0104] In some embodiments, the support frame 50 and the water distribution box 60 can be sealed by welding. For example, after the support frame 50 is placed over the opening, the assembly gap between the support frame 50 and the water distribution box 60 is welded. For example, the support frame 50 and the water distribution box 60 can be made of the same metal material, and the two can be welded together to seal the assembly gap.

[0105] As an optional implementation of the above embodiments, such as Figure 13 As shown, the support frame 50 is provided with a settling tank S3, which is connected to the water inlet channel 21. Figure 13 As shown, the water distribution box 60 is at least partially embedded in the settling trough S3, and the bottom cover 120 of the settling trough S3 is located at the opening, and the settling trough S3 and the water distribution chamber S4 are connected. In some embodiments, the space between the support frame 50 and the bottom of the washing drum 10 is limited. Therefore, a settling trough S3 is provided on the support frame 50, which allows the water distribution box 60 to be partially submerged in the support frame 50 without adjusting the space between the support frame 50 and the bottom of the washing drum 10, thus eliminating the need for structural modifications to the washing drum 10. In an embodiment, the settling trough S3 and the water distribution chamber S4 together form a sealed cavity, which is connected to the water inlet channel 21. Water flowing in through the rotating shaft 20 enters this sealed cavity.

[0106] In an embodiment, such as Figure 13 As shown, the sidewall of the water distribution box 60 is at least partially embedded in the settling tank S3, and the end of the sidewall facing the support frame 50200 is an open opening. The end face of the sidewall of the water distribution box 60 abuts against the bottom of the tank, such that the bottom cover 120 of the settling tank S3 is located at the opening. In an embodiment, the side of the sidewall abuts against the sidewall of the settling tank S3.

[0107] As an optional implementation of the above embodiments, such as Figure 13 As shown, a second sealing groove is formed on the support frame 50; the second sealing groove surrounds the settling tank S3; the water distribution assembly also includes a third sealing element 530; the third sealing element 530 is disposed within the second sealing groove; the water distribution box 60 abuts against the third sealing element 530. In this embodiment, water leakage can be prevented by the abutting between the water distribution box 60 and the third sealing element 530.

[0108] In an embodiment, such as Figure 13As shown, a sealing protrusion 610 is formed on the end face of the side wall of the water distribution box 60. This sealing protrusion 610 abuts against the third sealing member 530 to achieve a seal. Specifically, the sealing protrusion 610 is embedded in the second sealing groove, pressing the third sealing member 530 tightly. In this embodiment, the water distribution box 60 is provided with a first threaded hole, and the bottom of the groove is provided with a second threaded hole. The first threaded hole and the second threaded hole are locked together by a threaded component, thereby fixing the water distribution box 60 to the support frame 50 and generating pressure, causing the sealing protrusion 610 to be embedded in the second sealing groove, pressing the third sealing member 530 tightly.

[0109] The third seal 530 can be a sealing ring.

[0110] As an optional implementation of the above embodiments, such as Figure 13 As shown, the water distribution chamber S4 is annular; the at least two water outlets are evenly distributed around the circumference of the water distribution box 60. In this embodiment, the water distribution chamber S4 is annular, and the at least two water outlets are evenly distributed around the circumference of the water distribution box 60, so that the water flow rate distributed to each water outlet is basically the same, thereby ensuring that the water flow rate at the inlet position in the washing chamber S2 is basically the same. In a specific embodiment, combined with... Figure 12 As shown, there are three water outlets. There can also be two or more water outlets.

[0111] As an optional implementation of the above embodiments, Figure 13 As shown, the water inlet channel 21 has a channel outlet. The radial distance from the channel outlet to the at least two water outlets is the same. In this embodiment, the radial distance from the at least two water outlets to the channel outlet is the same, so that the water flow rate distributed to each water outlet is substantially the same, thereby ensuring that the water flow rate at the water inlet position in the washing chamber S2 is substantially the same.

[0112] It is understandable that at least two outlets are located on the same circle centered on the center of the channel outlet.

[0113] As an optional implementation of the above embodiments, such as Figure 13 As shown, a relief groove is formed on the support frame 50; the water outlet is connected to the water outlet connector 710; the water outlet connector 710 is at least partially embedded in the relief groove. In this embodiment, the water outlet connector 710 is used to lead water from the water outlet to the water distribution chamber S4. Embedding the water outlet connector 710 at least partially in the relief groove serves two purposes: firstly, the relief groove constrains the water outlet connector 710, reducing water flow disturbance that could cause large displacement of the water outlet connector 710 and lead to leakage; secondly, it reduces the axial space occupied by the water outlet connector 710 between the support frame 50 and the washing drum 10.

[0114] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
