[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0051] The embodiment of the present application provides a spray assembly and a laundry treatment device to solve the problem that when the existing washing machine dispenses detergent, the dissolution time of the detergent is short, resulting in a low dissolution rate of the detergent. The following will be described with reference to the accompanying drawings.

[0052] The spray assembly provided by the embodiment of the present application is applied to a laundry treatment device. The laundry treatment device includes a detergent box 5 and a washing tub 6. The spray assembly includes a housing 1 and a diverter 2. Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the spray assembly provided by the embodiment of the present application. Figure 2 which is an exploded view of the spray assembly provided by the embodiment of the present application. An accommodation space is provided inside the housing 1, and the accommodation space communicates with the detergent box 5 and the washing tub 6. The diverter 2 is arranged in the accommodation space. A baffle groove 23 is formed by a depression on one side of the diverter 2 close to the detergent box 5. The diverter 2 includes side walls 21 that enclose to form the baffle groove 23. Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the diverter of the spray assembly provided by the embodiment of the present application. Diversion holes 211 are provided through the side walls 21. An overflow channel 111 is formed between the side walls 21 and the housing 1. The diversion holes 211 communicate the baffle groove 23 and the overflow channel 111.

[0053] For the spray assembly provided by the embodiment of the present application, the baffle groove 23 of the diverter 2 blocks the liquid on the liquid flow path, so that bubbles are generated when the liquid impacts the baffle groove 23. When the bubbles burst, a large number of tiny droplets will be generated. These droplets can be better mixed with the detergent, thereby improving the dissolution rate of the detergent. At the same time, the bubbles increase the contact area between the detergent and water, which helps the detergent dissolve faster. Meanwhile, diversion holes 211 are provided on the side walls 21 of the baffle groove 23, so that the liquid in the baffle groove 23 can flow out of the baffle groove 23 through the diversion holes 211 and enter the washing tub 6 through the overflow channel 111.

[0054] Optionally, an air inlet hole 1211 is further provided on the housing 1. At least part of the air inlet hole 1211 is located downstream of the overflow channel 111 along the liquid flow direction. The cross-sectional area of the overflow channel 111 gradually decreases along the liquid flow direction, so that negative pressure suction is formed when the liquid flows through the air inlet hole 1211.

[0055] Since the cross-sectional area of the overflow channel 111 gradually decreases along the liquid flow direction, when the liquid flows through the tail section of the overflow channel 111, the flow rate is large and the pressure is small. Also, since at least part of the air inlet hole 1211 is located downstream of the overflow channel 111, that is, the flow rate of the liquid flowing through the air inlet hole 1211 is large and the pressure is small. Thus, gas can be adsorbed into the accommodation space of the housing 1 through the air inlet hole 1211 to increase the bubble content in the liquid, thereby increasing the dissolution rate of the detergent, the foam performance, reducing the surface tension of the washing solution, etc., and realizing the second foaming effect on the washing solution.

[0056] Optionally, please refer to Figure 5 , Figure 5This is an assembly cross-sectional view of the flow divider and the straightening ring of the spray assembly provided by the embodiments of the present application. The housing 1 includes a straightening ring 11. The straightening ring 11 is sleeved on the flow divider 2. An overflow channel 111 is formed by clamping between the straightening ring 11 and the side wall 21. The straightening ring 11 includes a first end face 112 facing the washing cylinder 6. The first end face 112 is located downstream of the diversion hole 211 along the liquid flow direction.

[0057] Since the first end face 112 of the straightening ring 11 is located downstream of the diversion hole 211, and at least part of the air inlet hole 1211 is located downstream of the overflow channel 111, that is, at least part of the air inlet hole 1211 is located downstream of the straightening ring 11, which is equivalent to the straightening ring 11 separating the diversion hole 211 and the air inlet hole 1211, preventing the diversion hole 211 and the air inlet hole 1211 from being in the same plane in the direction perpendicular to the liquid flow, and thus avoiding the liquid flowing out directly from the air inlet hole 1211 when flowing out of the diversion hole 211. That is, along the liquid flow direction, the liquid flowing out of the diversion hole 211 is always guided by the straightening ring 11. The cross-sectional area of the overflow channel 111 formed by clamping between the straightening ring 11 and the flow divider 2 becomes narrower from wide, realizing negative pressure suction of the liquid at the air inlet hole 1211, and thus increasing the bubble content in the washing solution.

[0058] In some examples, the straightening ring 11 includes a straightening rotating surface facing the flow divider 2 and surrounding the periphery of the flow divider 2. The inner diameter of the straightening rotating surface gradually becomes smaller along the liquid flow direction. The side wall 21 of the flow divider 2 can be a rotating body with a constant outer diameter along the liquid flow direction. At this time, the longitudinal section (the plane along the liquid flow direction) of the overflow channel 111 is approximately a right trapezoid. At the same time, since the straightening rotating surface is inclined towards the side wall of the flow divider, it guides the liquid in the overflow channel, so that the liquid in the overflow channel flows towards the middle of the accommodating space, avoiding the liquid flowing out of the overflow channel from leaking out through the air inlet hole.

[0059] In other examples, the straightening ring 11 includes a straightening rotating surface facing the flow divider 2 and surrounding the periphery of the flow divider 2. The inner diameter of the straightening rotating surface gradually becomes smaller along the liquid flow direction. The side wall 21 of the flow divider 2 can be a rotating body with an outer diameter gradually becoming smaller along the liquid flow direction. And the angle between the side wall 21 of the flow divider 2 and the vertical direction is smaller than the angle between the straightening rotating surface and the vertical direction, that is, ensuring that the cross-sectional area of the overflow channel 111 gradually becomes smaller along the liquid flow direction. At the same time, since the straightening rotating surface is inclined towards the side wall of the flow divider, it guides the liquid in the overflow channel, so that the liquid in the overflow channel flows towards the middle of the accommodating space, avoiding the liquid flowing out of the overflow channel from leaking out through the air inlet hole.

[0060] Optionally, please refer to Figure 4 , Figure 4It is a schematic structural diagram of the foam generator of the spray component provided by the embodiment of the present application. The housing 1 further includes a foam generator 12. The foam generator 12 is sleeved on one end of the rectifying ring 11 close to the washing cylinder 6. An overcurrent space 123 is provided in the foam generator 12. The overcurrent space 123 communicates with the overcurrent channel 111 and the washing cylinder 6. A plurality of air inlet holes 1211 penetrate through the foam generator 12.

[0061] By separately arranging the rectifying ring 11 and the foam generator 12, the overcurrent cross-section of the overcurrent channel 111 gradually becomes smaller along the liquid flow direction, and the air inlet holes 1211 are arranged downstream of the overcurrent channel 111, making the structure of each component simpler and facilitating processing and manufacturing. At the same time, since the air inlet holes 1211 are arranged on the foam generator 12, there is a certain interval between the air inlet holes 1211 and the liquid flowing out of the overcurrent channel 111 in the direction perpendicular to the liquid flow, further preventing the liquid from escaping from the air inlet holes 1211 and ensuring the air intake effect of the air inlet holes 1211.

[0062] In some examples, the plurality of air inlet holes 1211 are arranged at intervals along the circumferential direction of the foam generator 12.

[0063] Further, the air inlet hole 1211 includes a first part and a second part. The first part is located downstream of the rectifying ring 11, and the second part has a positive projection on the rectifying ring 11. That is, one part of the air inlet hole 1211 is misaligned with the rectifying ring 11 in the liquid flow direction, and the other part is aligned with a part of the rectifying ring 11 in the liquid flow direction. At this time, the first part of the air inlet hole 1211 ensures the negative pressure suction effect achieved by the cooperation of the air inlet hole 1211 and the liquid inlet channel, and the second part of the air inlet hole 1211 further improves the air intake efficiency of the air inlet hole 1211. Moreover, due to the shielding of the rectifying ring 11, no liquid will escape from the second part of the air inlet hole 1211. The shape of the air inlet hole 1211 is not further limited here and can be a round hole, a square hole, a diamond hole, etc.

[0064] Optionally, please refer to Figure 6 , Figure 6 It is an assembly sectional view of the diverter, rectifying ring and foam generator of the spray component provided by the embodiment of the present application. The foam generator 12 includes a surrounding plate 121 and a foam net 122. The surrounding plate 121 is sleeved on one end of the rectifying ring 11 close to the washing cylinder 6. A plurality of air inlet holes 1211 are provided on the surrounding plate 121, and an overcurrent space 123 is provided inside the surrounding plate 121; the foam net 122 is arranged in the overcurrent space 123, and a plurality of mesh holes 1221 are arranged at intervals on the foam net 122. The shape of the mesh holes 1221 is not further limited here and can be a honeycomb hole, a round hole or a square hole, etc.

[0065] That is, after the liquid flows out of the flow-through channel 111, it enters the flow-through space 123 of the baffle 121. When flowing through the foaming net 122, it collides with the foaming net 122 and generates bubbles. When the bubbles burst, a large number of tiny droplets are produced. These droplets can be better mixed with the detergent, thereby increasing the dissolution rate of the detergent. Moreover, the bubbles increase the contact area between the detergent and water, contributing to the faster dissolution of the detergent. The third foaming of the washing solution is achieved through the foaming net 122.

[0066] Optionally, the inner side of one end of the baffle 121 close to the rectifying ring 11 is recessed with an installation groove, and a clamping portion is protruded on the outer side of the rectifying ring 11. The clamping portion is clamped in the installation groove to realize the clamping and fixing of the baffle 121 and the rectifying ring 11.

[0067] In some examples, the baffle 121 includes a fixing portion, a plurality of connecting ribs and a plate body. The fixing portion is connected to the rectifying ring 11 and is provided with an installation groove. The plate body is annular and a foaming net 122 is installed inside the plate body. The plurality of connecting ribs are spaced and connected between the fixing portion and the plate body, and air inlet holes 1211 are formed between adjacent connecting ribs.

[0068] Optionally, the diverter 2 further includes a bottom wall 22 surrounding to form a flow blocking groove 23, and a drain hole 2211 is formed through the bottom wall 22. By providing the drain hole 2211, it is prevented that due to the slow flow rate of the diversion holes 211, the liquid in the flow blocking groove 23 stays, resulting in an overly slow supply rate of the washing solution. That is, through the drain hole 2211, it is prevented that the flow blocking groove 23 is blocked to ensure the supply rate of the washing solution.

[0069] Optionally, a plurality of flow disturbing protrusions 2212 are spaced on the side of the bottom wall 22 facing the detergent box 5, and the plurality of flow disturbing protrusions 2212 are spaced from the drain hole 2211.

[0070] By providing the flow disturbing protrusions 2212 on the bottom wall 22, the flow distance of the liquid is increased on the path of the liquid flowing from the bottom wall 22 of the flow blocking groove 23 to the side wall 21 of the flow blocking groove 23. At the same time, the flow disturbing protrusions 2212 also have a certain impact foaming effect on the liquid, further improving the foaming effect of the liquid in the flow blocking groove 23 and increasing the dissolution rate of the washing solution.

[0071] Optionally, the bottom wall 22 includes a base plate 221 and a boss 222. The base plate 221 is connected to the side wall 21; the boss 222 protrudes on the side of the base plate 221 facing the detergent box 5, the drain hole 2211 penetrates through the boss 222 and the base plate 221, and the plurality of flow disturbing protrusions 2212 are spaced on the boss 222 and / or the base plate 221 and are located in the flow blocking groove 23.

[0072] Since there is a height difference between the boss 222 and the substrate 221 in the flow direction of the liquid, when the liquid falls from the boss 222 to the substrate 221, it will first hit the boss 222 and then further hit the substrate 221. The boss 222 and the substrate 221 with a height difference realize two impacts on the liquid flow path, thereby increasing the foaming rate of the liquid.

[0073] In some examples, a plurality of spoiler protrusions 2212 are arranged at intervals on the boss 222; in some examples, a plurality of spoiler protrusions 2212 are arranged at intervals on the substrate 221; in some examples, some spoiler protrusions 2212 are arranged at intervals on the boss 222, and another portion of spoiler protrusions 2212 are arranged at intervals on the substrate 221. The shape of the spoiler protrusion 2212 is not further limited here, for example, it can be spherical, block-shaped, etc.

[0074] Optionally, an annular groove is provided on the side of the rectifying ring 11 close to the detergent box 5, and the side wall 21 of the diverter 2 may include a mounting plate and a plurality of connecting ribs. The mounting plate is annular and is installed in the annular groove. The plurality of connecting ribs are connected between the mounting plate and the bottom wall 22 at intervals. Diverter holes 211 are formed between adjacent connecting ribs, and the connecting ribs are connected to the side of the mounting plate away from the rectifying ring 11. Therefore, the connecting ribs and the mounting plate are offset from each other in a direction perpendicular to the flow direction of the liquid, thereby further increasing the effective impact area of ​​the diverter 2 on the liquid and improving the foaming rate of the washing solution.

[0075] That is, the diverter 2 divides the inside of the rectifying ring 11 into two spaces in the flow direction of the liquid, and the two spaces are connected through the diverter hole 211 of the diverter 2, so that the liquid is diverted and foamed by the diverter 2 before entering the flow channel 111.

[0076] Optionally, the clothes processing device further includes a door seal 4, and the spray assembly further includes a connecting seat 3, and the connecting seat 3 includes a seat body 31 and a connecting pipe 32. The seat body 31 is installed on the door seal 4, and the seat body 31 is provided with a connecting hole 311. The housing 1 is connected to one side of the seat body 31, and the accommodating space connects the connecting hole 311 of the seat body 31 with the washing tub 6; the connecting pipe 32 connects the connecting hole 311 of the seat body 31 with the detergent box 5.

[0077] The connection seat 3 is used to fix the spray assembly to the door seal 4, and to connect the housing 1 to the detergent box 5 and the washing drum 6. The fixing structure of the seat 31 and the door seal 4 is not further limited here. In some examples, the seat 31 is provided with a fixing hole, and the seat 31 is fixed to the door seal 4 by a fixing member passing through the fixing hole. In other examples, the seat 31 is provided with a fixing member, and the door seal 4 is provided with a fixing hole, and the fixing member is installed in the fixing hole. The fixing member can be a latch, a screw, a rivet, etc.
