Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] The laundry tub assembly includes a laundry tub 3 and an internal component positioned within the tub. At least a portion of the tub's surface is coated with a PP-Si layer 2, a novel elastomer formed by the perfect combination of silicone and polyolefin. Through specialized compatibility and dynamic vulcanization techniques, fully vulcanized silicone rubber is evenly dispersed throughout the polyolefin as soft, microparticle islands, creating a unique sea-island structure that offers a wide range of hardness, exceptional softness, and resilience, significantly reducing wear on clothing.

[0043] See Figure 1 The components inside the barrel include a pulsator 11. The upper surface and the peripheral side surfaces of the pulsator 11 are provided with a PP-Si layer 2, that is, the PP-Si layer 2 completely covers the pulsator 11. The PP-Si layer 2 is embedded in the pulsator 11 through a connecting member 21. The peripheral side surfaces of the pulsator 11 are provided with an embedding groove. The connecting member 21 is connected to the embedding groove. The PP-Si layer 2 is embedded in the embedding groove through the connecting member 21 to prevent the PP-Si layer 2 from falling off.

[0044] See Figures 2 to 4 The impeller 11 is also provided with a plurality of water-repelling blades 112 and a plurality of drainage holes 113. The PP-Si layer 2 covers the water-repelling blades 112, and a connecting member 21 is also provided at the corresponding position of the PP-Si layer 2 and the drainage hole 113. The connecting member 21 extends into the drainage hole 113 and extends to the bottom of the drainage hole 113. The connecting member 21 is connected to an anti-slip structure 22. The anti-slip structure 22 and the connecting member 21 together form an inverted "T" shape to prevent the PP-Si layer 2 from bulging or falling off.

[0045] In this preferred embodiment, the PP-Si layer completely covers the impeller 11 and covers the water-repelling blades 112 on the impeller 11, but this is not restrictive. The PP-Si layer 2 can also be covered only on the surface of the water-repelling blades 112, or it can be covered in other areas. Those skilled in the art can set it according to actual conditions.

[0046] In another embodiment, an anti-slip structure is also provided at the end of the connecting member 21 on the peripheral side of the PP-Si layer 2 in the embedding direction to further prevent the peripheral side from falling off.

[0047] Furthermore, since the connecting member 21 extends into the drainage hole 113 , it will block the drainage hole 113 and affect drainage. Therefore, a drainage hole 211 is provided on the connecting member 21 so that water can be discharged from top to bottom.

[0048] In addition, see Figure 1 and 3 The circumferential side of the impeller 11 is provided with a plurality of protrusions 111, and the PP-Si layer 2 is provided with through holes at positions corresponding to the protrusions 111, and the protrusions 111 pass through the through holes and extend to the outside of the through holes. Figure 1 The direction shown is the reference direction, and the right side of the protrusion 111 is located to the right of the right side of the PP-Si layer 2. Figure 3 The direction shown is the reference direction. The left side of the protrusion 111 is located to the left of the left side of the PP-Si layer 2. When the impeller rotates, if an offset occurs, the protrusion 111 will be rubbed first, preventing the PP-Si layer 2 on the peripheral side from being worn.

[0049] See next Figure 5 ,like Figure 5 As shown, the clothing processing barrel 3 includes an outer barrel 31 and an inner barrel 32 arranged in the outer barrel 31. The internal components of the barrel include a lint filter 12. Part of the lint filter 12 is located in the inner barrel 32. A plurality of PP-Si layers 2 are arranged in an array in a partial area on the surface of the lint filter 12. At this time, the PP-Si layer 2 is a plurality of raised scattered points to prevent wear on the clothes when the clothes hit the lint filter 12.

[0050] Continue reading Figure 5 The inner part of the barrel also includes a friction cleaning block 13, which is arranged on the inner wall of the inner cylinder 32. A PP-Si layer 2 is arranged on the friction cleaning block 13, and the PP-Si layer 2 completely covers the friction cleaning block 13. Specifically, refer to Figure 6 ,like Figure 6 As shown in FIG, the peripheral area a of the PP-Si layer 2 is embedded in the friction cleaning block 13 through a connecting member 21, and an anti-slip structure 22 is provided at the end of the embedding direction of the connecting member 21 to prevent the peripheral area a from falling off. The non-peripheral area of ​​the PP-Si layer 2 (i.e. Figure 6 The area between the two a's is also provided with a connecting member 21, and the non-peripheral area is also embedded in the friction and decontamination block 13 through the connecting member 21, and an anti-slip structure 22 is provided at the end of the embedding direction to avoid bulging or bulging in the middle area.

[0051] Figure 5 The connection method between the PP-Si layer 2 on the lint filter 12 and the lint filter 12 is not shown in the figure. Instead, the connection method between the friction cleaning block 13 and the PP-Si layer 2 can be adopted. It will be understood by those skilled in the art that the PP-Si layer 2 can cover the entire exposed surface of the lint filter 12 and the friction cleaning block 13, or it can cover a portion of the surface. Those skilled in the art can determine the connection method based on actual conditions.

[0052] See next Figure 7The inner part of the barrel also includes a spray water channel 14, which is arranged on the inner wall of the inner cylinder 32. The inner cylinder 32 is provided with a pulsator 11. Under the rotation of the pulsator 11, the water in the inner cylinder 32 enters the spray water channel 14 and is finally sprayed from the nozzle 141 of the spray water channel 14 to the interior of the inner cylinder 32. The PP-Si layer 2 is a plurality of convex structures arranged on the surface of the spray water channel 14, such as Figure 8 As shown, the PP-Si layer 2 is embedded into the inner wall of the spray channel 14 via a connecting member 21, and an anti-slip structure 22 is provided at the end of the connecting member 21 in the embedding direction. Of course, this is only one preferred arrangement. In another embodiment, the PP-Si layer 2 is a layered structure covering the outer surface of the spray channel 14, covering the entire outer surface of the spray channel 14, leaving a position for the nozzle 141.

[0053] In order to realize the circulating spraying of water, the utility model adopts the rotation of the impeller 11 to provide power, but this is not restrictive. In another embodiment, a water receiving chamber is provided below the impeller 11, and a driving water pump is provided in the water receiving chamber. The water receiving chamber and the spray water channel 14 are connected. A drainage hole is provided on the impeller 11, and the water in the inner cylinder 32 is discharged into the water receiving chamber through the drainage hole, driving the water pump, driving the water into the spray water channel 14, and finally spraying it out through the nozzle 141. Those skilled in the art can set it by themselves according to actual conditions.

[0054] Continue reading Figure 4 The spray hole 23 is located in the middle position of the axis direction of the clothing processing barrel 3, and the spray hole 23 penetrates the PP-Si layer 2 and the connecting component 21 and the anti-slip structure 22 located in the middle position and is connected to the spray water channel 14. Based on the above structural setting, the water entering the spray water channel 14 is divided into two parts, one part is sprayed out from the spray hole 23, and the other part is sprayed out from the nozzle 141. The two parts of three-dimensional washing water flow spray on the clothes to improve the cleaning effect.

[0055] Furthermore, an accommodating groove 142 is provided on the inner surface of the inner wall of the spray water channel 14 , and the accommodating groove 142 can accommodate the anti-slip structure 22 . Based on the above arrangement, it is possible to avoid occupying the water flow space in the spray water channel 14 .

[0056] Furthermore, the PP-Si layer 2 is a raised structure arranged on the surface of the spray water channel 14, and a groove 143 is provided at the corresponding position of the PP-Si layer 2. The raised structure portion is located in the groove 143, and the other portion of the raised structure is exposed outside the groove 143 and extends a preset distance in the direction away from the spray water channel 14. The setting of the groove 143 can protect the PP-Si layer 2. When the lower side of the PP-Si layer 2 is hit by clothing, the upper side of the groove 143 will provide an opposite force to offset it. When the lower side of the PP-Si layer 2 is hit by clothing, the upper side of the groove 143 will provide an opposite force to offset it, thereby avoiding large displacement or offset of the PP-Si layer 2 after being hit by a large collision force.

[0057] Next, see Figures 9 to 11 A lifting rib 15 is provided on the inner wall of the inner tube 32, and a PP-Si layer 2 is provided on the lifting rib 15. The PP-Si layer 2 is embedded in the lifting rib 15 through a connecting member 21, and an anti-slip structure 22 is provided at the end of the embedding direction. The peripheral area and the middle area of ​​the PP-Si layer 2 are connected to the lifting rib 15 through the connecting member 21 and the anti-slip structure 22 to avoid stripping or bulging in the middle area. A first embedding hole 151 is provided in the peripheral area of ​​the lifting rib 15, and the peripheral connecting member 21 is matched and connected with the first embedding hole 151. A support member 152 is provided in the middle position of the lifting rib 15, and a second embedding hole 1521 is provided on the support member 152. The second embedding hole 1521 passes through the lifting rib 15 and the support member 152, and the connecting member 21 located in the middle is matched and connected with the second embedding hole 1521.

[0058] See Figure 12 In another embodiment, the connection method between the PP-Si layer 2 and the lifting rib 15 is the same as Figure 11 The same as in the embodiment of the present invention, the only difference is that the portion of the PP-Si layer 2 outside the lifting rib 15 is a convex structure, and a protective groove 153 is provided at the corresponding position of the lifting rib 15, the convex structure portion is located in the protective groove 153, and the other portion of the convex structure is exposed outside the protective groove 153 and extends a preset distance in the direction away from the lifting rib 15. The setting of the protective groove 153 can protect the PP-Si layer 2. When the left side of the PP-Si layer 2 is hit by clothing, the right side of the protective groove 153 will provide an opposite force to offset it. When the right side of the PP-Si layer 2 is hit by clothing, the left side of the protective groove 153 will provide an opposite force to offset it, thereby avoiding a large displacement or offset of the PP-Si layer 2 after being subjected to a large collision force.
